As a basic component of many rubber products, the dimensional accuracy, surface quality, and cutting efficiency of rubber strips are directly related to the quality and efficiency of subsequent forming processing. This trend has prompted manufacturers to seek higher-standard processing technologies to ensure the reliability and competitiveness of final products.

[0004] For the numerical control strip cutting machine designed in the above-mentioned disclosed patent with a limiting function, the position of the limiting plate is adjusted through the adjusting component on the mounting frame, and the distance between the two limiting plates can be adjusted according to the width of the material to limit the movement of the material. However, only the position of the limiting plate is adjusted by a threaded rod, and this mechanical adjustment method may have certain limitations in actual operation. Since there is no designed matching guiding mechanism while limiting the strip cutting raw material, it is easy for the strip cutting raw material to bulge during the continuous pushing process, resulting in unstable and reduced cutting accuracy. Therefore, how to design a high-precision limit numerical control strip cutting machine has become a problem to be solved currently. Summary of the Utility Model
[0005] In order to overcome the defect that when the numerical control strip cutting machine in the prior art cuts strips only by limiting, the strip cutting raw material is prone to bulge or shift, the utility model provides a high-precision limit numerical control strip cutting machine.

[0012] The beneficial effects of the present utility model are as follows: 1. By designing the limiting plate I and the limiting plate II, both can slide along the guide rod and can adjust their positions through threaded connection. At the same time, the left and right sides and the top surface of the rubber plate are limited, and a rotating wheel is provided to assist the limiting plate I in limiting the rubber plate, which can effectively prevent the rubber plate from bulging or shifting during the transmission process, ensuring the stability and accuracy of the material during the cutting process.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which the presently preferred embodiments of the present utility model are shown. However, the present utility model can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.
[0020] Embodiment: A high-precision limiting numerical control strip cutting machine, as Figure 1 、 Figure 2 and Figure 4As shown in the figure, it includes a machine base 1, on which a conveying module 2 for conveying rubber strips is installed. There are multiple cutting grooves on one side of the conveying module 2. It also includes: a mounting frame 3 installed on the top of the machine base 1; a motor 4 installed on one side of the mounting frame 3; a rotating rod 41 installed on the output shaft of the motor 4, and the end of the rotating rod 41 is installed on the other side of the mounting frame 3 through a bearing; multiple blades 5 installed on the rotating rod 41, and the blades 5 are respectively located in the cutting grooves of the conveying module 2; a conveyor belt 6 arranged on the conveying module 2; two groups of guide rods I 7 arranged on the machine base 1, and the two groups of guide rods I 7 are arranged across the conveyor belt 6 of the conveying module 2; two groups of support plates 8 fixedly connected to the machine base 1, and the support plates 8 respectively fit the guide rods I 7; a bidirectional lead screw 9 rotatably installed between the support plates 8 of the same group; a limit plate I 10 symmetrically slidably connected to the guide rods I 7, and the limit plate I 10 is symmetrically threadedly connected to the bidirectional lead screw 9; a limiting member arranged on the conveying module 2, and the limiting member is used to limit the height of the rubber plate conveyed on the conveyor belt 6 to prevent the rubber plate from bulging during limited conveying; the overall shape of the blade 5 is a crescent structure, and the blade 5 is detachably installed on the rotating rod 41 through bolts, and the blades 5 on the rotating rod 41 can be flexibly increased or decreased as needed.
[0021] As Figure 2 shown, the limiting member includes guide rods II 11, a threaded rod 12 and a limit plate II 13. The two guide rods II 11 are respectively installed at positions on the conveying module 2 corresponding to the guide rods I 7. The threaded rod 12 is symmetrically rotatably installed on the opposite sides of the guide rods II 11 on the conveying module 2. The limit plate II 13 is correspondingly arranged between the corresponding guide rods II 11 and the threaded rod 12. The limit plate II 13 is slidably connected to the guide rods II 11 and threadedly connected to the threaded rod 12. By screwing the threaded rod 12, the limit plate II 13 is limited to the rubber plate conveyed on the conveyor belt 6 to prevent the rubber plate from bulging.
[0022] As Figure 1 and Figure 2 shown, it also includes a fixed shaft 14 and a rotating wheel 15. The planes of the limit plate I 10 and the limit plate II 13 for limiting the rubber plate are both processed with smooth chamfers; the limit plate I 10 is an inverted U-shaped plate structure. The fixed shaft 14 is fixedly connected inside the limit plate I 10. The rotating wheel 15 is rotatably installed at the lower end of the fixed shaft 14, and the rotating wheel 15 is used to guide the rubber plate limited by the limit plate I 10.
[0023] As Figure 3As shown, the guiding contact surface of the rotating wheel 15 slightly protrudes from the opposite sides of the limiting plate I 10. The rotating wheel 15 can rotate and press on the rubber plate, facilitating the smooth conveyance of the rubber plate on the conveying module 2 under the limitation of the limiting plate I 10.
[0024] Place the rubber plate to be cut on the left side of the conveying module 2. When the rubber plate contacts the conveyor belt 6, by enabling the conveyor belt 6, the conveyor belt 6 will drive the rubber plate to slide from left to right on the conveying module 2. When the rubber plate moves between the limiting plates I 10, temporarily turn off the conveyor belt 6, and by turning the bidirectional lead screw 9, the bidirectional lead screw 9 drives the symmetric limiting plates I 10 on it to contract inward and clamp the rubber plate. Before the limiting plates I 10 are about to clamp the rubber plate, the rotating wheel 15 will contact the rubber plate in advance, and the rotating wheel 15 will rotate and press on the two side edges of the rubber plate. Then the user turns the threaded rod 12 to drive the limiting plate II 13 on the guide rod II 11 to move downward until the limiting plate II 13 moves down and adheres to the top surface of the rubber plate. The limiting plate II 13 can horizontally limit the top surface of the rubber plate, further improving the limiting accuracy of the rubber plate. After enabling the conveyor belt 6 again, the rubber plate can move smoothly under the combined action of the guiding of the rotating wheel 15 and the limitation of the limiting plate II 13. Finally, after installing the blade 5 on the rotating rod 41, enable the motor 4 to drive the rotating rod 41 and the blade 5 on it to rotate at a high speed, thereby cutting the rubber plate conveyed under stable limitation with high precision.
[0025] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
