Description

The speed reduction mechanism of the four wheels of the cigarette pack forming equipment

Technical Field

The present invention relates to the technical field of cigarette pack forming equipment, and in particular to the structural improvement of four wheels of cigarette pack forming equipment.

Background technique

The existing cigarette pack forming equipment has four wheels that move intermittently. There is a Martha gear mechanism inside the gear box of the four wheels, which can control the angle of each mold box rotated by the four wheels. In other words, each mold box will pause once. The original four wheels have 24 mold boxes, so the four wheels will pause 24 times for one rotation. The reason for the pause is that when the cigarette packs are transferred from the third wheel to the fourth wheel, the two wheels cannot rotate.

With the needs of cigarette box packaging, when it is necessary to increase the heating and ironing time of the folded cigarette boxes, the existing four-wheel cigarette pack forming equipment cannot achieve this. If the rotation speed of the four-wheel is simply slowed down, it will affect the synchronous cooperation with the three-wheel, and the power output equipment must also be modified. Not only is the modification cost high, it also directly affects production efficiency.

Summary of the invention

In summary, the purpose of the present invention is to solve the technical deficiency that the four wheels of the existing cigarette pack forming equipment cannot extend the heating and ironing time of the cigarette pack in the four wheels, and to propose a speed reduction mechanism for the four wheels of the cigarette pack forming equipment.

In order to solve the technical problem proposed by the present invention, the technical solution adopted is:

The reduction mechanism of the four wheels of the cigarette pack forming equipment is characterized in that: the reduction mechanism includes an active internal gear fixedly connected to the power output shaft of the power output device, the active internal gear is connected to the driven external gear through more than three sets of planetary gear sets in the same direction of reduction transmission, and the driven external gear is fixedly connected to the mold box wheel cocentrically; the planetary gear set is movably connected to the planetary gear bracket through the shaft, and the planetary gear bracket is fixedly connected to a clamping device for fixed connection to the shell of the power output device.

The end of the clamp is provided with a flange, which is fixedly connected to the planetary gear bracket via a connecting seat.

The connecting seat includes a fixing plate, the upper side of the fixing plate is provided with an upper boss axially slidably connected to the flange of the clamp, and the lower side of the fixing plate is provided with a lower boss inserted into the planetary gear bracket; a fastening screw is also provided between the fixing plate and the planetary gear bracket.

The mold box wheel comprises a mold box rear base fixedly connected to the driven external gear, and 36 mold boxes are installed on the mold box rear base in a circumferential distribution.

The beneficial effects of the present invention are as follows: the present invention realizes the deceleration of the mold box wheel while keeping the rotation speed of the original power output device unchanged, and increases the number of mold boxes to adapt to the synchronous cooperation with the three wheels. In order to maximize the pause time of the cigarette pack in the four wheels, the number of the four-wheel mold boxes is increased to 36, so that the four wheels need to pause 36 times for each rotation, and each rotation is 360/36=10 degrees. To reduce the four wheels from the original 15-degree pause once to 10-degree pause once, an angle conversion is required, so as to achieve the effect of extending the heating and ironing time of the cigarette pack in the four wheels.

Detailed ways

The structure of the present invention is further described below in conjunction with the accompanying drawings and preferred specific embodiments of the present invention.

1 to 5, the four-wheel speed reduction mechanism of the cigarette pack forming equipment of the present invention includes an active internal gear 1 fixedly connected to the power output shaft of the power output device, the active internal gear 1 is connected to the driven external gear 3 through more than three sets of planetary gear sets 2 in the same direction by speed reduction transmission, and the driven external gear 3 is fixedly connected to the mold box wheel 4 cocentrically; the planetary gear set 2 is movably connected to the planetary gear bracket 5 through the shaft, and the planetary gear bracket 5 is fixedly connected to the clamp 6 used for being fixedly connected to the housing of the power output device.

When the power output shaft of the power output device drives the active internal gear 1 to rotate at the original speed, since the planetary gear bracket 5 and the clamp 6 are fixed and do not make circular motion, the active internal gear 1 drives the driven external gear 3 to reduce the circular motion through the planetary gear set 2, and the mold box wheel 4 moves synchronously with the driven external gear 3. In this embodiment, each set of planetary gear sets 2 is composed of two planetary gears meshing with each other, ensuring that the driven external gear 3 can rotate asynchronously with the active internal gear 1 in the same direction.

In order to realize that one mold box can cooperate synchronously with the three wheels every time the mold box wheel stops running, the mold box wheel 4 includes a mold box rear base 41 fixedly connected to the driven outer gear 3, and 36 mold boxes 42 are circumferentially installed on the mold box rear base 41. That is, the original 24 mold boxes are increased to 36 mold boxes, and the residence time of the cigarette pack in the mold box 42 is increased, thereby achieving the effect of extending the heating and ironing time of the cigarette pack in the four wheels.

The end of the clamp 6 is provided with a flange 61, which is fixedly connected to the planetary gear bracket 5 through a connecting seat 62, thereby ensuring that the planetary gear bracket 5 does not make a circular motion. In order to achieve appropriate axial sliding between the clamp 6 and the planetary gear bracket 5 and improve adaptability; the connecting seat 62 includes a fixing plate 621, the upper side of which is provided with an upper boss 622 axially slidably connected to the flange 61 of the clamp, and the lower side of the fixing plate 621 is provided with a lower boss 623 inserted into the planetary gear bracket 5; a fastening screw is also provided between the fixing plate 621 and the planetary gear bracket 5.

In order to enhance the dust-proof effect, a dust cover 63 is provided between the flange 61 of the clamp 6 and the planetary gear bracket 5 , and an inner dust cover 64 is also provided on the inner side of the dust cover 63 .

The invention meets the demand of extending the heating and ironing time of the four wheels without making any improvement to the original power output device and the three wheels, and the transformation cost is low.
