[0002] Rubber injection vulcanization equipment is a new technology for the production of rubber molded products. It is mainly used in the production of rubber products, such as insulating parts, shock absorbers, automotive seals, etc. Recently, it has been increasingly widely used at home and abroad. In the rubber injection vulcanization equipment, the shape of the rubber used is not arbitrary and irregular. Generally, strip-shaped rubber is used as the raw material of the injection vulcanization equipment.

[0003] Currently, the Chinese utility model patent: CN 206242129 U has been published, which discloses a rubber material slitting machine for injection vulcanization equipment. The hob on the new model is a cylindrical structure and a blade with a circular ring structure is arranged on the outer periphery. A plurality of hobs are detachably arranged on the driven shaft, so the spacing between the hobs is adjustable, thereby adjusting the width of the rubber sheet after slitting. Therefore, the utility model has high adjustability and can adapt to a variety of different rubber sheets, which not only greatly reduces the labor intensity of workers, but also improves production efficiency.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: when the rubber material slitting machine is in use, the rollers on the driven shaft can be disassembled and assembled, and the spacing between the rollers can be adjusted, thereby adjusting the width of the rubber sheet after slitting. However, the rubber directly enters the interior of the slitting machine for shearing. Since the rubber is not limited and guided before shearing, the rubber is easily offset during shearing, affecting the quality of the rubber shearing and slitting. Utility Model Content

If there is a description of first and second, it is only for the purpose of distinguishing technical features, and it cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the order of the indicated technical features. In the description of the present utility model, unless otherwise clearly defined, the terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meaning of the above terms in the present utility model in combination with the specific content of the technical solution.

[0020] See also Figure 1-4 The utility model provides a technical solution: an automatic rubber slitting device, comprising a frame 1 and a rubber guide limit device, a conveyor belt 2 is arranged on the left side of the frame 1, two support frames 3 are fixedly connected to the top of the frame 1, longitudinal shearing slitting knives 4 (one each at the top and the bottom, arranged in a scissor-like staggered manner) are installed inside the two support frames 3, a positioning guide wheel 5 is installed on the top (right side) of the frame 1, and four protrusions 6 are fixedly connected to the right side (front and rear positions) of the frame 1.

[0021] When the rubber automatic slitting equipment is in use, the rubber gradually slides from the upper side of the positioning guide wheel 5 to the left side and enters the position between the longitudinal slitting knives 4. At this time, the longitudinal slitting knife 4 can shear and slit the rubber. The slitting rubber moves to the left side to the surface of the conveyor belt 2, and the slitting rubber is transported by the conveyor belt 2.

[0022] The rubber guide limit device includes a guide rod 7, two slides 8, two guide frames 9, a side roller 11, a bidirectional threaded rod 12 and a circular turntable 13. The guide rod 7 is fixedly installed inside the two upper protrusions 6. The two slides 8 are slidably sleeved on the surface of the guide rod 7. The two guide frames 9 are respectively welded on the top of the two slides 8. The surfaces of the two guide frames 9 are provided with grooves 10. The side roller 11 is rotatably installed inside the groove 10. The bidirectional threaded rod 12 is threadedly sleeved inside the two slides 8. The front and rear ends of the bidirectional threaded rod 12 are provided with threads in opposite directions. The bidirectional threaded rod 12 is rotatably installed inside the two lower protrusions 6. The circular turntable 13 is fixedly connected to the rear end of the bidirectional threaded rod 12. The two guide frames 9 are respectively located on both sides of the positioning guide wheel 5.

[0023] The staff rotates the bidirectional threaded rod 12 through the circular turntable 13. The rotation of the bidirectional threaded rod 12 can drive the two slide plates 8 to slide relative to each other, and the two slide plates 8 are guided and limited by the guide rod 7, so as to ensure that the two slide plates 8 slide back and forth horizontally. The relative sliding of the two slide plates 8 can drive the two guide frames 9 on the top to slide relative to each other. The two guide frames 9 slide and drive the side rollers 11 on both sides to slide and clamp the surface of the rubber. When the rubber slides, the side rollers 11 can be driven to rotate by friction, and then the rubber is guided and limited by the side rollers 11 on both sides, so that the rubber slides horizontally for shearing, thereby preventing the rubber from deviating during shearing, and improving the quality of rubber shearing and stripping.

[0024] An annular groove 14 is formed inside the two slide plates 8 , and a ball 15 is slidably mounted in a circular shape inside the annular groove 14 , and the surface of the ball 15 contacts the surface of the guide rod 7 .

[0025] During the sliding of the two slides 8 on the surface of the guide rod 7, the slides 8 slide and drive the ball 15 to roll on the surface of the guide rod 7 through the annular groove 14, and then the friction of the slide 8 sliding on the surface of the guide rod 7 is reduced through the rolling of the ball 15. By converting the sliding friction into rolling friction, the resistance of the two slides 8 sliding on the surface of the guide rod 7 is reduced, ensuring that the staff can drive the two slides 8 to slide stably back and forth through the bidirectional threaded rod 12.

[0026] Working principle: In the rubber automatic slitting equipment, the staff rotates the bidirectional threaded rod 12 through the circular turntable 13. The rotation of the bidirectional threaded rod 12 can drive the two slide plates 8 to slide relative to each other, and the two slide plates 8 are guided and limited by the guide rod 7. The relative sliding of the two slide plates 8 can drive the two guide frames 9 on the top to slide relative to each other. The two guide frames 9 slide and drive the side rollers 11 on both sides to slide and clamp the surface of the rubber. When the rubber slides, the side rollers 11 can be driven to rotate by friction, and then the rubber is guided and limited by the side rollers 11 on both sides, so that the rubber slides horizontally for shearing. The slide plate 8 slides and drives the ball 15 to roll on the surface of the guide rod 7 through the annular groove 14, and then the friction of the slide plate 8 sliding on the surface of the guide rod 7 is reduced by the rolling of the ball 15, ensuring that the staff drives the two slide plates 8 to slide back and forth stably through the bidirectional threaded rod 12.

[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
