DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0021] Please refer to Figures 1-3 As shown, this embodiment provides a cutting device for the production of rubber and plastic products, including a mounting frame 1. On both sides of the mounting frame 1, a pair of conveying rollers 2 are rotatably installed. A driving motor (not shown in the figure) for driving the rotation of the conveying rollers 2 is installed on the mounting frame 1. A fixed frame 3 is fixedly installed at the top of the mounting frame 1. A threaded rod 4 is rotatably installed at the top of the fixed frame 3. A driving motor for driving the rotation of the threaded rod 4 is installed on the fixed frame 3. A slider 5 threadedly connected to the threaded rod 4 is slidably installed through the top of the fixed frame 3. An electric telescopic rod 6 is fixedly installed at the bottom of the slider 5. A cutter 7 is installed at the bottom of the electric telescopic rod 6. An ultrasonic device for causing the cutter 7 to vibrate at high frequency is installed on the cutter 7, which is convenient for cutting rubber products and making the cutting more accurate. The two pairs of conveying rollers 2 are used to convey rubber products on the top of the mounting frame 1. The electric telescopic rod 6 is used to press the cutter 7 onto the rubber products, and then the rotating threaded rod 4 drives the cutter 7 to cut along the cutting line of the rubber products through the slider 5, so as to achieve the purpose of accurately cutting rubber products;

[0022] Chutes 8 are provided on both sides of the top of the mounting frame 1. Two symmetrically arranged push plates 9 are slidably installed through the chutes 8. A number of balls are rotatably installed on the opposite sides of the two push plates 9. A sliding plate 10 is slidably installed at the bottom of the top plate of the mounting frame 1. Two symmetrically arranged connecting plates 11 are rotatably installed at the positions of the sliding plate 10 corresponding to each pair of push plates 9. One end of the connecting plate 11 away from the sliding plate 10 is rotatably connected to the bottom of the corresponding push plate 9. A fixing plate 12 is fixedly installed on one side of the bottom of the top plate of the mounting frame 1. A sliding rod 13 is slidably installed through the fixing plate 12. One end of the sliding rod 13 is fixedly connected to one side of the sliding plate 10. A tension spring 14 sleeved on the outer peripheral wall of the sliding rod 13 is fixedly installed between the other end of the sliding rod 13 and the fixing plate 12;

[0023] When one push plate 9 moves away from another symmetrically arranged push plate 9, this push plate 9 will drive the sliding plate 10 to move backward in the conveying direction through the connecting plate 11, thereby driving the sliding rod 13 to act on the tension spring 14, making the tension spring 14 in a stressed state. At the same time, the other symmetrically arranged push plate 9 moves away from this push plate 9 by the same distance under the action of the other connecting plate 11. On the contrary, the two push plates 9 will approach each other by the same distance, that is, the two symmetrically arranged push plates 9 move towards each other. When the spring is in a stretched state, it has a tendency to rebound, so as to make the two symmetrically arranged push plates 9 tend to approach each other through the sliding rod 13, the sliding plate 10 and the connecting plate 11. When the rubber products deviate during conveying, the two pairs of push plates 9 tending to approach each other will correct the rubber products on both sides of the rubber products;

[0024] On both sides of the cutting knife 7, there are extrusion components 15. The extrusion component 15 includes a sliding bracket 151 that is slidably installed through the mounting bracket 1. At the bottom of the sliding bracket 151, a support frame 152 is fixedly installed. At the bottom of the support frame 152, a rotating cylinder 153 is rotatably installed. Between the top of the support frame 152 and the mounting bracket 1, a number of compression springs 154 are fixedly installed;

[0025] The support frame 152 can only drive the rotating cylinder 153 to move in the vertical direction under the restriction of the sliding bracket 151. The support frame 152 drives the rotating cylinder 153 to press against the top of the mounting bracket 1 under the extrusion of a number of compression springs 154. The rubber product is pressed against the top of the top plate of the mounting bracket 1 through the extrusion of the rotating cylinder 153, avoiding the cutting part of the rubber product from separating from the top of the mounting bracket 1 and reducing the cutting accuracy.

[0026] When the utility model is in use, the rubber product is installed between two pairs of conveying rollers 2 for conveying the rubber product. When the rubber product deviates during conveying, two pairs of oppositely moving push plates 9 will correct the deviated rubber product from both sides of the rubber product so that it will no longer deviate during conveying. Then, the two rotating cylinders 153 press the cutting part of the rubber product against the top of the top plate of the mounting bracket 1. Then, the cutting knife 7 is moved to the cutting area of the rubber product, and the cutting knife 7 is driven to move from one side of the rubber product to the other side by the rotating threaded rod 4 to complete the cutting of the rubber product.

[0027] The above is only a preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
