DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As mentioned in the background art, when disassembling the roller body in the prior art, it is necessary to pull the pins on both sides simultaneously and then the roller body can be removed. Therefore, it is difficult for a single person to disassemble. The present utility model provides a rubber pulling device for rubber production.

[0023] Embodiment 1

[0024] Referring to Figures 1 to 2 , a rubber pulling device for rubber production includes a workbench 1, a winding mechanism 2 and a bracket 3 are arranged on the workbench 1, and a cylinder 4 is arranged on the bracket 3;

[0025] Connecting rods 5 are arranged at the output end of the cylinder 4 and on the workbench 1;

[0026] Support plates 6 are arranged on the opposite sides of the two connecting rods 5, and rollers 7 are inserted on the opposite sides of the two support plates 6. One end of the rubber is passed through the bracket 3 and fixed to the winding roller of the winding mechanism. The upper roller 7 is lowered by the cylinder 4 until the distance between the two rollers 7 is appropriate for squeezing the rubber. At this time, the winding mechanism 2 is started, and the winding mechanism 2 will wind the rubber. Pins 8 inserted on the rollers 7 penetrate through both sides of the support plate 6, and a return spring 9 connected to the support plate 6 is arranged on the pin 8. The above are all prior arts;

[0027] In order to facilitate the simultaneous removal of the pins 8 on both sides, convex rods 10 are arranged on the pins 8 on both sides;

[0028] A through groove 11 is formed in the connecting rod 5. Push rods 12 penetrate horizontally through both sides of the through groove 11. The two push rods 12 face the convex rods 10 on both sides respectively. Moving the push rod 12 can move the convex rod 10, and thus the pin 8 can be moved;

[0029] Moving components are arranged on the two connecting rods 5. The moving components are connected to the two push rods 12, and the moving components are used to drive the two push rods 12 to move in opposite directions.

[0030] Two moving components are provided in this solution and are respectively installed on the two connecting rods 5, or can be provided separately. When one of the rollers 7 needs to be disassembled, the moving component can be installed on this connecting rod 5 for use, which can reduce costs.

[0031] In order to prevent the push rod 12 from disengaging from the through groove 11 due to excessive force, stop pieces are arranged on the opposite sides of the two push rods 12, and the two stop pieces are both located in the through groove 11.

[0032] The moving component includes a guide rod 13 vertically connected inside the connecting rod 5. A slider 14 is slidably sleeved on the guide rod 13. A support spring 16 connected to the connecting rod 5 is provided on the slider 14. Oblique rods 15 hinged to the push rod 12 are hinged on both sides of the slider 14. By moving the slider 14 in the direction close to the roller 7, the support spring 16 is compressed, so that the oblique rods 15 can push the push rods 12 on both sides to squeeze the convex rods 10 on both sides, realizing the simultaneous movement of the pins 8 on both sides, so as to facilitate pushing the slider 14 with one hand and taking out the roller 7 with the other hand.

[0033] In order to guide the support spring 16, the support spring 16 is sleeved outside the guide rod 13.

[0034] Embodiment 2

[0035] Referring to Figure 2 , in order to facilitate the movement of the slider 14, the front end of the slider 14 is located on the front side of the front end of the connecting rod 5, so as to reduce the obstruction of the connecting rod 5 during movement.

[0036] All the other structures are the same as those in Embodiment 1.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
