Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

Embodiment 1

This embodiment is used to solve the problem that the characteristics of engineering tire cords are large width, large steel wire diameter, heavy cord weight, and high requirements on splicing quality. As a result, defects in the spliced cords need to be detected on the unloading conveyor belt, and the defects cannot be detected in time. The defective spliced cords are subject to effective supervision and targeted remedial treatment, which leads to quality control problems in the finished tire spliced cords.

The end face of the manual suture device 4 is provided with a support frame 403 connected to the body of the combined bracket 104. The end of the swing conveyor belt 101 away from the support frame 403 is movably connected. The glued conveyor belt 3, the glued conveyor belt 3 and the swing conveyor belt 101 are equipped with a lifting platform 2 on the side; a frame 201 is provided at the bottom of the lifting platform 2, a control panel 5 is provided on the outer wall of the bottom of the frame 201, and a control panel 5 is provided on the top of the frame 201 A platform 205 is provided, and a safety carpet 206 is provided on the top of the platform 205;

The control panel 5 is internally provided with a processor, a data acquisition module, a self-test feedback module and a signal execution module; the data acquisition module is used to collect the cloth deviation value Q and the docking gap value W within the curtain time threshold, and combine the cloth deviation value Q and the docking gap value The gap value W is sent to the self-test feedback module through the processor, and 60 minutes within the device's glue-bonding and docking transportation time period is set as the time threshold;

It should be noted that the fabric deviation value Q is expressed as the maximum and minimum values of the left and right deviation angles of the cord splicing obtained within the time threshold, and the value of the fabric deviation value Q reflects the splicing fit of the cord. The larger the value, the The lower the fit of the cord splicing, the easier it is for splicing gaps between multiple sets of cords to occur. The butt gap value W represents the size of the gap that exists in the splicing area of multiple sets of cords within the time threshold. In addition, the cloth deviation value Q is located in the unloading mechanism 1 is collected by the electro-optical correction sensor installed above, and the gap deviation value W is collected by the infrared scanning sensor installed above the swing conveyor belt 101;

After receiving the fabric deviation value Q and the docking gap value W, the self-test feedback module immediately analyzes the docking fit efficiency of the equipment. The specific analysis process is as follows:

Obtain the cloth deviation value Q and the butt gap value W of the cord within the time threshold, and use the formula Obtain the fitting efficiency coefficient Di, where a and b are the proportional coefficients of the cloth deviation value Q and the docking gap value W respectively, a>b>0, Di represents the fitting efficiency coefficient, and the stored preset is immediately retrieved from the processor Comparative analysis of the fit efficiency coefficient Fi and the fit efficiency coefficient Di;

If the fit efficiency coefficient Di ≥ the preset fit efficiency coefficient Fi, it is determined that the butt-jointed cords on the swing conveyor belt 101 and the adhesive conveyor belt 3 have an assembly abnormality, an auxiliary splicing signal is generated, and the generated auxiliary splicing signal is sent to the signal execution via the processor module, the signal execution module immediately controls the lifting platform 2 to operate after receiving the auxiliary splicing signal. When the spliced assembled abnormal cord is transported to the unloading mechanism 1, the lifting platform 2 drives the step 205 to adjust the position upward through the lifting cylinder 202. The platform 205 moves along the guide shaft 203, and cooperates with the linear bearing 204 to rise and slide upward until the platform 205 slides up and is lifted close to the unloading mechanism 1 and close to the swing conveyor belt 101. When the platform 205 rises and stabilizes, the operator Climb and move to the lifting platform 2 via the external ladder frame, and walk along the platform 205 to the safety carpet 206. When someone stops on the safety carpet 206, the lifting platform 2 cannot be operated. The operator who stops on the safety carpet 206 holds a manual The stitching device 4 releases the restriction of the winding drum 402. The winding drum 402 is driven by an internal micromotor to pay off the thread. The operator holds the manual stitching device 4 to manually splice the cord fabrics with large gaps in the splicing combination;

If the fitting efficiency coefficient Di < the preset fitting efficiency coefficient Fi, no signal is generated.
