Abstract
The invention discloses a winding core covered with a soft material, which comprises a winding core body and a soft material layer covering the outside surface of the winding core body, wherein the soft material layer flatly covers the outside of the winding core body. The winding core of the invention overcomes the drawback that the conventional common winding core for producing polaroids is susceptible to causing unqualified products on a part close to the winding core during winding, can effectively avoid forming unqualified products, and is simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of volume core that the rolling used in the polaroid process is used of producing.
Background technology
The coventional type rolling that the production polaroid is used is a kind of column type volume core of making of plastic material with the volume core.Mainly there is following shortcoming in common rolling with its function of volume core: when using the rolling of volume core with the coventional type rolling, because polaroid directly is wrapped in the outside face of volume core, when some is arrived in rolling, because rolling will be used tension force, damaged by pressure the formation defective products so cause close volume in-core layer segment product can twine tighter and tighter and make near volume core segment product.Take-up diameter is big more, and the defective products that forms near volume core segment product is just many more.
Summary of the invention
The technical problem to be solved in the present invention is: overcome coventional type rolling that existing production polaroid uses and form the defective of defective products when the rolling easily near the volume core segment with the volume core, propose a kind of volume core that is surrounded by soft material that can effectively avoid forming defective products.
In order to solve the problems of the technologies described above, the present invention proposes following technical scheme: a kind of volume core that is surrounded by soft material, comprise a volume core body, this volume core comprises that also one is coated on the soft material layer on this this external surface of volume core, and this soft material layer entirely is coated on the outside of this volume core body.
Preferably, this soft material layer is made with soft material.
Preferably, the thickness range of this soft material layer is 0.5-10mm.
Patent of the present invention has following beneficial effect: among the present invention, volume core body is existing common volume core, outside face at volume core body directly coats one deck soft material and forms a soft material layer, because polaroid is not directly to contact with the outside face of volume core body during rolling, but polaroid is wrapped on the soft material layer of rolling up on this external surface of core.Because the soft material layer has certain elasticity and shrink space, certain compensator or trimmer pressure effect is arranged, so polaroid can not prevent to form defective products near the portioned product of volume core body by actv. because of rolling tension force more around tight more, it is simple, easy to use that the present invention rolls up cored structure.
Description of drawings
Fig. 1 is a kind of block diagram that is surrounded by the volume core of soft material of the present invention.
Fig. 2 is a kind of schematic cross-section that is surrounded by the volume core of soft material of the present invention.
Fig. 3 is the schematic cross-section of the other direction of a kind of volume core that is surrounded by soft material of the present invention.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of volume core 1 that is surrounded by soft material comprises the soft material layer 14 that a volume core body 12, is coated on this volume core body 1 outside face.
This soft material layer 14 entirely is coated on the outside of this volume core body 12.
This soft material layer 14 can be made with any suitable soft material, and the thickness range of this soft material layer 14 is 0.5-10mm.
Use this volume core that is surrounded by soft material 1 rolling polaroid when (figure does not show), polaroid is twisted in the outside face of this soft material layer 14, and polaroid contacts with above-mentioned soft material layer 14.
The definition of term and symbol in the patent specification of the present invention is hereinafter described.
(1) height of the volume core body 12 that refers to of symbol " H ";
(2) symbol " R " refers to the outside radius of volume core body 12;
(3) symbol " L " refers to the girth of volume core body 12.
The first method that making the present invention is surrounded by the volume core 1 of soft material comprises the steps:
Step 1: measure the outside radius R and the height H of the core body 12 that makes the test earlier, calculate the perimeter L of the core body 12 that makes the test, L=2* π * R;
Step 2: cut out the size dimension that coats the soft material of rolling up core body 12 needs according to the perimeter L of the volume core body 12 that calculates and the height H of volume core body 12, and respectively paste three Acrylic Foam Tapes along length L direction upper, middle and lower at soft material;
Step 3: the soft material that will be stained with Acrylic Foam Tape is entirely tightly pasted along the length L direction and the outside face of volume core body 12, and soft material is pasted with adhesive tape in the outside face intersection of volume core body 12 again.
The second method that making the present invention is surrounded by the volume core 1 of soft material comprises the steps:
Step 1: select a kind of suitable rubber by batching, sample preparation, a series of programs of tested for hardness;
Step 2: the rubber that chooses wrapped in according to ad hoc approach and technology be placed on oven for baking behind the steel die outside face and be shaped, this steel die external diameter R is identical with the external diameter size of the volume core body 12 that needs coating;
Step 3: will be inserted in the volume core body 12 that need to coat from the shaping gum cover after the steel die demoulding, and carry out the polishing of gum cover surface accurate then and be machined to the composite demand outward appearance and get final product.
Among the present invention, volume core body 12 is existing common volume cores, outside face at volume core body 12 directly coats one deck soft material and forms a soft material layer 14, because polaroid is not directly to contact with the outside face of volume core body 12 during rolling, but polaroid is wrapped on the soft material layer of rolling up on core body 12 outside faces 14.Because soft material layer 14 has certain elasticity and shrink space, certain compensator or trimmer pressure effect is arranged, so polaroid can be because of rolling tension force more around not tight more, can actv. prevent to form defective products near the portioned product of volume core body 12, it is simple in structure, easy to use that the present invention is surrounded by the volume core 1 of soft material.
