Description

Technical Field

[0001] The present invention relates to a steel cord cutting and splicing device, and particularly to an auxiliary conveying mechanism for the splicing tip of a steel cord. Background Art

[0002] A steel cord is a tire component with rubber coated on a steel cord.

[0003] The steel cord roll is unrolled on a steel cord cutting and splicing device and cut into single steel cord sheets (parallelogram shape) with a certain angle and width. After the head and tail of each steel cord sheet are spliced, they are wound into a roll for use by a forming machine.

[0004] The splicing process of the steel cord is as follows: The long steel cord strip on the splicing conveyor belt is in a waiting state. The feeding conveyor belt conveys the triangular head of the steel cord sheet and aligns it with the triangular tail of the long steel cord strip. The splicing wheel aligns and splices the head and tail edges of the two steel cord sheets together. The splicing conveyor belt conveys the spliced long steel cord strip forward while leaving the tail at the splicing position, waiting for the next steel cord sheet to be conveyed and aligned for splicing.

[0005] During the splicing process of the steel cord, the long steel cord strip stays on the stationary splicing conveyor belt. The single steel cord sheet is conveyed from the feeding conveyor belt. The triangular head of the steel cord sheet rushes into the splicing conveyor belt by inertia and just positions at the tail of the long steel cord strip.

[0006] The steel cord is a soft thin sheet and has a certain viscosity. Especially when the triangular head of the single steel cord sheet is too wide and too long, due to the resistance, the triangular head of the steel cord sheet cannot be conveyed to the splicing position, and the splicing wheel cannot squeeze the head and tail sides of the steel cord together, resulting in possible splicing failure. Summary of the Invention

[0007] Aiming at the deficiencies of the prior art, the present invention proposes an auxiliary conveying mechanism for the splicing tip of a steel cord that conveys the triangular tip head of the single steel cord sheet in place during splicing.

[0008] The auxiliary conveying mechanism for the splicing tip of a steel cord that can solve the above technical problems includes a tip auxiliary conveyor belt arranged side by side outside the splicing conveyor belt. The tip auxiliary conveyor belt is flush with the front entrance of the splicing conveyor belt and is arranged at the rear exit of the feeding conveyor belt. A pressing wheel that acts on the tip auxiliary conveyor belt to provide conveying power for the steel cord sheet is provided at the entrance of the tip auxiliary conveyor belt. Driven by respective independent servo motors, the tip auxiliary conveyor belt, the splicing conveyor belt, and the feeding conveyor belt can operate independently, or the tip auxiliary conveyor belt can operate synchronously with the feeding conveyor belt, or the tip auxiliary conveyor belt, the feeding conveyor belt, and the splicing conveyor belt can operate synchronously.

[0009] To prevent the spliced long steel cord strip from being carried away by the tip auxiliary conveyor belt during operation, one measure is to set a partition between the outer side of the isolated long steel cord strip (already spliced) and the tip auxiliary conveyor belt at the rear of the splicing line.

[0010] To prevent the spliced long steel cord strip from being carried away by the tip auxiliary conveyor belt during operation, another measure is to set a point magnetic suction plate at the rear of the splicing line that can suck the outer side of the long steel cord strip (already spliced) away from the tip auxiliary conveyor belt.

[0011] Advantages of the present invention:

[0012] 1. The steel cord splicing tip auxiliary conveying mechanism of the present invention is suitable for splicing steel cord sheets with angles and widths, can solve the problem of inaccurate transmission of wide steel cord sheets, and improves the accuracy and efficiency of steel cord joints.

[0013] 2. In the structure of the present invention, the three conveyor belts adopt the same transmission parameters, which is easy to realize the synchronous operation of each conveyor belt and is convenient for control.

[0014] 3. The present invention uses a tip auxiliary conveyor belt to assist in the transmission of the tip of the steel cord sheet. When the tip of the steel cord sheet enters the splicing conveyor belt area, although the splicing conveyor belt does not move, the tip auxiliary conveyor belt runs synchronously with the feeding conveyor belt, enabling the steel cord sheet to obtain auxiliary conveying power and accurately reach the splicing position. The tip auxiliary conveyor belt does not require a backward movement, the synchronous distance is not limited, and the synchronous accuracy is high.

[0015] 4. The present invention uses a tip auxiliary conveyor belt to force the transmission of the tip of the steel cord sheet. The tip auxiliary conveyor belt does not require a backward movement, does not need to increase the travel of the steel cord sheet, and does not affect the splicing efficiency of conventional-width steel cord sheets.

[0019] The technical solutions of the present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0020] The auxiliary conveying mechanism for the tip of the spliced steel cord fabric of the present invention includes a tip auxiliary conveyor belt 2 provided outside the spliced conveyor belt 1. The tip auxiliary conveyor belt 2 is arranged parallel and side by side with the spliced conveyor belt 1. The front end inlet of the spliced conveyor belt 1 is flush with the front end inlet of the tip auxiliary conveyor belt 2 and is jointly arranged at the rear end outlet of the feeding conveyor belt 3. The spliced conveyor belt 1 adopts a conventional conveyor belt width, and the width of the tip auxiliary conveyor belt 2 is a supplement to the width of the spliced conveyor belt 1. The total width between the tip auxiliary conveyor belt 2 and the spliced conveyor belt 1 (including the spacing distance between the two) is equal to the width of the feeding conveyor belt 3; above the front parts of the tip auxiliary conveyor belt 2 and the spliced conveyor belt 1, there is a splicing mechanism with an adjustable angle. The direction of the splicing mechanism, that is, the splicing line 5, is an oblique direction inclined backward and outward, and this oblique angle corresponds to the degree of the tip triangular area of the steel cord fabric sheet 9, such as Figure 1 , Figure 2 shown.

[0021] The tip auxiliary conveyor belt 2, the spliced conveyor belt 1, and the feeding conveyor belt 3 are respectively driven by their own independent servo motors. According to the requirements of the production process, the tip auxiliary conveyor belt 2, the spliced conveyor belt 1, and the feeding conveyor belt 3 can operate independently respectively. The tip auxiliary conveyor belt 2 can also operate synchronously with the feeding conveyor belt 3. The tip auxiliary conveyor belt 2, the spliced conveyor belt 1, and the feeding conveyor belt 3 can also operate synchronously together, such as Figure 1 , Figure 2 shown.

[0022] At the front end inlet of the tip auxiliary conveyor belt 2, there is a pressing wheel 4 (with its own power) pressing on the tip auxiliary conveyor belt 2. The position of the pressing wheel 4 corresponds to the front tip of the triangular head of the steel cord fabric sheet 9, and the pressing wheel 4 can be adjusted left and right according to the position of the tip of the steel cord fabric sheet 9 with different widths, such as Figure 1 , Figure 2 shown.

[0023] A partition 6 is arranged at the rear side of the splicing line 5 and is in position alignment with the tip auxiliary conveyor belt 2. The partition 6 isolates between the outside of the long steel cord fabric strip 8 (already spliced) and the tip auxiliary conveyor belt 2, such as Figure 1 shown.

[0024] Or an electromagnetic suction plate 7 is arranged at the rear side of the splicing line 5 and is in position alignment with the tip auxiliary conveyor belt 2. The electromagnetic suction plate 7 can suck up the outside of the long steel cord fabric strip 8 (already spliced) and separate it from the tip auxiliary conveyor belt 2, such as Figure 2 shown.

[0025] The process steps for splicing the steel cord fabric using the present invention are as follows:

[0026] 1. The cut steel cord fabric sheets 9 are conveyed on the feeding conveyor belt 3 towards the spliced conveyor belt 1 and the tip auxiliary conveyor belt 2.

[0027] 2. When the steel cord fabric sheet 9 is conveyed close to the tip auxiliary conveyor belt 2, the servo motor starts to drive the tip auxiliary conveyor belt 2 to run synchronously with the feeding conveyor belt 3. When the tip of the triangular head of the steel cord fabric sheet 9 enters the tip auxiliary conveyor belt 2, under the forced feeding action of the pressing wheel 4 pressing on the tip, the tip auxiliary conveyor belt 2 and the feeding conveyor belt 3 jointly convey the triangular head of the steel cord fabric sheet 9 to the splicing line.

[0028] Due to the isolation by the partition plate 6 or the upward adsorption by the electromagnetic suction plate 7 on the outer side of the spliced long steel cord fabric strip 8, when the tip auxiliary conveyor belt 2 and the feeding conveyor belt 3 run synchronously, the long steel cord fabric strip 8 is not driven and stays at the splicing position.

[0029] 3. After splicing is completed, the feeding conveyor belt 3, the splicing conveyor belt 1 and the tip auxiliary conveyor belt 2 run synchronously together to convey the triangular tail end of the steel cord fabric sheet 9 spliced on the long steel cord fabric strip 8 to the splicing line 5.

[0030] When the feeding conveyor belt 3, the splicing conveyor belt 1 and the tip auxiliary conveyor belt 2 run synchronously, the electromagnetic suction plate 7 loses power and places the outer side of the long steel cord fabric strip 8 on the tip auxiliary conveyor belt 2.
