It is mainly used to cut rubber products, plastics and non-metallic materials into specific sizes or shapes. It adopts automatic feeding and cutting functions, which can realize continuous production process, reduce manual intervention and improve production efficiency. However, when using existing automatic cutting equipment, it lacks the function of guiding rubber products. Longer rubber products will be offset in position as they are conveyed by the conveyor belt and cut frequently by the cutting blade, thus affecting the shape of the final rubber strip. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic rubber product cutting device to solve the problem that the automatic cutting device mentioned in the background art lacks a guiding function for rubber products. As long rubber products are transported by the conveyor belt and cut frequently by the cutting blade, their position will shift, thus affecting the shape of the final rubber strip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic rubber product cutting device, comprising:

[0006] The machine body includes an automatic cutting machine, the surface of which is provided with cutting blades;

[0007] A guiding mechanism includes a connecting groove fixedly connected to the surface of an automatic cutting machine. A guide knob is rotatably connected to the surface of the connecting groove.

[0016] 1. By connecting the connecting groove and the guide knob, and connecting the guide knob and the clockwise threaded rod, the clockwise threaded rod can rotate following the rotation of the guide knob. Then, by connecting the clockwise threaded rod and the connecting rod, and connecting the connecting rod and the counterclockwise threaded rod, the clockwise and counterclockwise threaded rods can rotate synchronously. By connecting the clockwise threaded rod and the connecting plate, and connecting the counterclockwise threaded rod and the connecting plate, the two sets of connecting plates can move towards each other following the rotation of the clockwise and counterclockwise threaded rods. Finally, by connecting the connecting plate and the guide rod, and connecting the guide plate and the damping spring, the deformation of the damping spring can drive the guide plate to flexibly clamp onto the surface of the rubber product, achieving the effect of guiding the rubber product.

[0017] 2.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] An automatic rubber product cutting device, comprising:

[0027] The machine body includes an automatic cutting machine 1, and a cutting blade 11 is provided on the surface of the automatic cutting machine 1. Both the automatic cutting machine 1 and the cutting blade 11 are existing products and are not considered as technical protection points of this application. They will not be described in detail here.

[0028] The guiding mechanism includes a connecting groove 2, which is fixedly connected to the surface of the automatic cutting machine 1 for connecting a clockwise threaded rod 22 and a counterclockwise threaded rod 24. A guide knob 21 is rotatably connected to the surface of the connecting groove 2 for driving the clockwise threaded rod 22 and the counterclockwise threaded rod 24 to rotate. A clockwise threaded rod 22 is fixedly connected to the surface of the guide knob 21 for driving the connecting plate 25 to move by its own rotation. A connecting rotating rod 23 is fixedly connected to the end of the clockwise threaded rod 22 away from the guide knob 21 for connecting the clockwise threaded rod 22 and the counterclockwise threaded rod 24. A counterclockwise threaded rod 24 is fixedly connected to the end of rod 23 away from the clockwise threaded rod 22, which is used to drive the connecting plate 25 to move by its own rotation. The surface of the clockwise threaded rod 22 is threadedly fitted with the connecting plate 25, which is used to drive the guide plate 27 to move. The surface of the connecting plate 25 is movably connected with the guide rod 26, which is used to limit the movement position of the guide plate 27. The surface of the guide rod 26 is fixedly connected with the guide plate 27, which is used to guide the rubber product. The surface of the guide rod 26 is wound with a damping spring 28, which is used to drive the guide plate 27 to act on the surface of the rubber product by its own deformation.

[0029] Furthermore, the clockwise threaded rod 22 is internally rotatably connected to the connecting groove 2 via the guide knob 21, and the counterclockwise threaded rod 24 is internally rotatably connected to the connecting groove 2 via the guide knob 21. Rotating the guide knob 21 can drive the clockwise threaded rod 22, the connecting rod 23, and the counterclockwise threaded rod 24 to rotate synchronously. The thread grooves on the surfaces of the clockwise threaded rod 22 and the counterclockwise threaded rod 24 rotate in opposite directions, thereby causing the connecting plates 25 on their surfaces to move in opposite directions.

[0030] Furthermore, the connecting plates 25 are symmetrically distributed in two sets on both sides of the connecting rod 23. The connecting plates 25 are movably connected to the surface of the connecting groove 2 via the clockwise threaded rod 22 and the connecting plate 2 via the counterclockwise threaded rod 24. The two sets of connecting plates 25 move towards each other as the clockwise threaded rod 22 and the counterclockwise threaded rod 24 rotate, thereby driving the two sets of guide plates 27 to move towards each other.

[0031] Furthermore, the guide rods 26 are evenly distributed on the surface of the connecting plate 25, and the guide plate 27 is movably connected to the surface of the connecting plate 25 through the guide rods 26. The distribution of multiple sets of guide rods 26 is to prevent the guide plate 27 from shifting its position or tilting itself during the guiding process, which would affect the guiding efficiency of the rubber product.

[0032] Furthermore, the two ends of the damping spring 28 are fixedly connected to the surfaces of the connecting plate 25 and the guide plate 27. The guide plate 27 is movably connected to the surfaces of the connecting plate 25 through the damping spring 28. The two sets of guide plates 27 move towards each other as the two sets of connecting plates 25 move, thereby acting on the surface of the rubber product. The damping spring 28 is deformed by the compression of the guide plate 27, thereby making the guide plate 27 flexibly clamped on the surface of the rubber product without affecting the conveying of the rubber product.

[0033] Furthermore, the limiting mechanism includes a connecting rod 3, which is fixedly connected to the surface of the cutting blade 11 and used to connect a fixed shaft 31. The surface of the connecting rod 3 is fixedly connected to the fixed shaft 31 and used to connect a rotating pressure roller 33. A damping torsion spring 32 is wound around the surface of the fixed shaft 31 and used to drive the rotating pressure roller 33 to act on the surface of the rubber product through its own deformation. The surface of the fixed shaft 31 is rotatably connected to the rotating pressure roller 33 and used to pre-press it onto the surface of the rubber product.

[0034] Furthermore, the connecting rods 3 are evenly distributed in four groups on the surface of the cutting blade 11, and the fixed shafts 31 are symmetrically distributed in two groups on the surface of the connecting rods 3. The four groups of connecting rods 3 are used to connect the four groups of fixed shafts 31, so that the four groups of rotating pressure rollers 33 act alternately on the surface of the rubber product.

[0035] Furthermore, the rotating pressure roller 33 is rotatably connected to the surface of the cutting blade 11 via the fixed shaft 31. The two ends of the damping torsion spring 32 are fixedly connected to the surface of the fixed shaft 31 and the interior of the rotating pressure roller 33. The rotating pressure roller 33 is rotatably connected to the surface of the fixed shaft 31 via the damping torsion spring 32. When the cutting blade 11 moves downward to cut the rubber product, the connecting rod 3 will cause the rotating pressure roller 33 to contact the rubber product first, thereby causing the damping torsion spring 32 to deform and cause the rotating pressure roller 33 to press against the surface of the rubber product, preventing the rubber product from shifting during cutting.

[0036] Working principle: When using the automatic cutting machine 1, the rubber product is first placed on the surface of the automatic cutting machine 1. Then, as needed, the guide knob 21 is rotated to drive the clockwise threaded rod 22, the connecting rod 23, and the counterclockwise threaded rod 24 to rotate synchronously. The two sets of connecting plates 25 move towards each other following the rotation of the clockwise threaded rod 22 and the counterclockwise threaded rod 24. The two sets of guide plates 27 move towards each other following the movement of the two sets of connecting plates 25, thus acting on the surface of the rubber product. The damping spring 28 is deformed by the compression of the guide plate 27, so that the guide plate 27 is flexibly clamped on the surface of the rubber product without affecting the conveying of the rubber product. Then, the rubber product is cut. When the cutting blade 11 moves downward to cut the rubber product, the connecting rod 3 drives the rotating pressure roller 33 to contact the rubber product first. This causes the damping torsion spring 32 to deform and drive the rotating pressure roller 33 to press firmly on the surface of the rubber product, preventing the rubber product from shifting during cutting.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
