[0026] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0027] See also Figures 1-4 The utility model provides a rubber cutting machine for polymer material production, including a support platform 1 and a cutter 3. A through cutter groove 11 for the cutter 3 to enter is provided in the middle of the support platform 1. Vertical frames 12 extending vertically upward are symmetrically fixed on both sides of the support platform 1. A suspension 13 is fixed to the top of the two vertical frames 12. A guide rod 2 is slidably installed on the suspension 13. A first driving mechanism 4 is provided above the suspension 13. The first driving mechanism 4 is used to drive the guide rod 2 to move vertically up and down. The cutter 3 is fixed to the bottom end of the guide rod 2 and corresponds to the position of the cutter groove 11.

[0028] When the rubber cutting machine provided by the present invention cuts rubber materials, the rubber materials are placed on the support platform 1, and the first driving mechanism 4 drives the guide rod 2 to descend vertically, thereby driving the cutter 3 to descend and enter the knife groove 11, and the cutter 3 can be used to cut the rubber material. The first driving mechanism 4 continues to work, and can drive the guide rod 2 to move upward, thereby driving the cutter 3 to move upward and reset, thereby completing the entire step of cutting the rubber material.

[0029] Specifically, a vertically extending sleeve 14 is fixed on the suspension 13, the sleeve 14 passes through the suspension 13, and the guide rod 2 is slidably installed in the sleeve 14. By arranging the sleeve 14 on the suspension 13 and sliding the guide rod 2 in the sleeve 14, the sleeve 14 can provide a limiting guide and support effect for the sliding of the guide rod 2, ensuring that the lifting and lowering process of the guide rod 2 is smooth and stable enough.

[0030] Specifically, the first driving mechanism 4 includes a fixed seat 41, a first driving motor 42, a rotating disk 43, an eccentric rod 44 and a limiting plate 45. The first driving motor 42 is fixed above the suspension 13 through the fixed seat 41. The rotating disk 43 is fixedly mounted on the output shaft end of the first driving motor 42. The eccentric rod 44 is rotatably mounted on the rotating disk 43 and deviates from the output shaft end of the first driving motor 42. The limiting plate 45 is fixed to the top end of the guide rod 2 and extends horizontally. The limiting plate 45 is provided with a limiting groove 451 extending along its length direction. The eccentric rod 44 fits in the limiting groove 451 and can slide along the inner wall of the limiting groove 451. When the first driving motor 42 works, its output shaft drives the rotating disk 43 to rotate, thereby driving the eccentric rod 44 to swing eccentrically. Under the limiting action of the eccentric rod 44 and the limiting groove 451, the limiting plate 45 and the guide rod 2 can be driven to periodically rise and fall as a whole, thereby providing drive for the lifting action of the cutter 3.

[0031] The utility model drives the turntable 43 to rotate by the first drive motor 42, which can drive the eccentric rod 44 to swing eccentrically and drive the limit plate 45 and the guide rod 2 to rise and fall, so as to realize the cutting and resetting action of the cutter 3. Compared with the traditional technology, the method of using the spring for resetting is eliminated, and there is no need to consider the influence of the spring elastic failure. The operation is stable, and there is no need to regularly shut down for maintenance and replacement of accessories. It is easy to use and has high processing efficiency.

[0032] Specifically, two mounting frames 5 are symmetrically arranged on both sides of the support platform 1, and a conveyor belt 6 is installed on each mounting frame 5. The rubber material is placed on the support platform 1 and between the conveyor belts 6 on both sides to ensure that both sides of the rubber material are in contact with the conveyor belts 6 respectively. When the conveyor belts 6 are in operation, the friction force can be used to drive the rubber material forward, thereby realizing the feeding and transportation of the rubber material.

[0033] Specifically, there is a gap 61 between the two mounting frames 5 on the same side, and the position of the cutter 3 corresponds to the position of the gap 61 on both sides. In order to avoid the cutter 3 from being blocked and colliding with the mounting frame 5 and the conveyor belt 6 as a whole, a gap 61 is reserved between the two mounting frames 5 on the same side to avoid the cutter 3 from colliding with the mounting frame 5 and the conveyor belt 6 as a whole.

[0034] Specifically, a second driving mechanism 7 is provided at the bottom of the support platform 1. The second driving mechanism 7 is used to drive the mounting frames 5 on both sides to move closer to or away from each other. The second driving mechanism 7 drives the mounting frames 5 on both sides to move closer to or away from each other, so that the distance between the conveyor belts 6 on both sides can be adjusted to adapt to the transportation of rubber materials of different widths, which greatly increases the versatility of the rubber cutting machine.

[0035] Specifically, the second drive mechanism 7 includes a guide seat 71, a bidirectional threaded rod 72, a second drive motor 73, a pair of nut seats 74, a pair of mounting plates 75 and four C-shaped connecting arms 76. The guide seat 71 is fixed to the lower surface of the support platform 1. A guide groove 711 is provided on the guide seat 71. The bidirectional threaded rod 72 is rotatably mounted in the guide groove 711. The second drive motor 73 is fixed to one end of the guide seat 71. The output shaft of the second drive motor 73 is fixedly connected to one end of the bidirectional threaded rod 72. The two nut seats 74 are symmetrically limited and slidably mounted in the guide groove 711 and threadedly matched. On both sides of the bidirectional threaded rod 72, the lower ends of the two nut seats 74 are fixed with mounting plates 75, and two C-shaped connecting arms 76 are symmetrically fixed on the mounting plate 75. The ends of the four C-shaped connecting arms 76 are fixedly connected to the four mounting brackets 5 in a one-to-one correspondence. The second drive motor 73 works, and its output shaft drives the bidirectional threaded rod 72 to rotate. The rotating bidirectional threaded rod 72 can threadably drive the two nut seats 74 to approach or move away from each other. Under the fixed connection between the mounting plate 75 and the C-shaped connecting arm 76, the mounting brackets 5 on both sides can be driven to approach or move away from each other.

[0036] Since the rubber material is soft and has a large friction force with the surface of the support platform 1, placing the rubber directly on the upper surface of the support platform 1 will result in large friction resistance during transportation, making transportation difficult and not smooth. In order to solve this problem, the present invention makes the following improvements:

[0037] Specifically, mounting grooves 101 are provided on both sides of the knife groove 11 on the upper surface of the support platform 1. Guide rollers 102 are installed in an array in the two mounting grooves 101 in a rotating manner along the rubber conveying direction. By arranging the guide rollers 102 above the support platform 1, the rubber material is placed on the guide rollers 102. When conveying the rubber, the guide rollers 102 can roll, thereby reducing the friction resistance of the rubber material when it moves forward, ensuring that the rubber material conveying process is smooth, fluent and labor-saving.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
