[0015] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0016] Detailed implementation method: combined with Figure 1-4As shown, a rubber cutting device includes a belt conveyor 1 and a controller 3, and a frame 2. The frame 2 has a channel 26 extending through both sides. The belt conveyor 1 is located on one side of the frame 2. The bottom surface of the channel 26 is on the same plane as the upper surface of the conveyor belt on the belt conveyor 1, or the bottom surface of the channel 26 is slightly lower than the upper surface of the conveyor belt on the belt conveyor 1. On the side of the bottom surface of the channel 26 away from the belt conveyor 1, there are multiple vertically extending notches 21 connected end-to-end. The two sides of each notch 21 are parallel and perpendicular to the extension direction of the belt conveyor 1, respectively. These multiple notches 21 form a step-like shape, and the extension direction of this step is parallel to the belt conveyor 1. The extension direction of machine 1 is inclined. A knife holder 23 is slidably connected to the frame 2. The knife holder 23 is located in the channel 26. A cutter 231 is provided on one side of the bottom of the knife holder 23, which cooperates with the multiple notches 21 connected end to end. The cutter 231 can cut the rubber located below it from the notch 21. A pressure seat 24 is also placed above the knife holder 23 and slidably connected to it. A pressure plate 241 is provided on one side of the pressure seat 24. The pressure plate 241 is located on the side of the cutter 231 (and the notch 21) close to the belt conveyor 1. When the bottom surface of the pressure seat 24 contacts the top surface of the knife holder 23, the lower end of the pressure plate 241 is lower than the lower end of the cutter 231. The top surface of the knife holder 23 is connected to the piston of the hydraulic cylinder 25 located on the top of the frame 2. In use, a sheet of rubber is placed on the belt conveyor 1. The belt conveyor 1 is then started so that the front end of the rubber extends from the notch 21 closest to the belt conveyor 1, with the extended length not exceeding the length of the notch 21 (the length is parallel to the extension direction of the belt conveyor 1). The belt conveyor 1 then stops running, and the cutter head 23 falls. The pressure plate 241 first contacts the part of the rubber near the notch 21. The cutter head 23 continues to fall, at which point almost all the weight of the pressure seat 24 is borne by the pressure plate 241, which presses the part of the rubber near the notch 21 firmly into place. On the bottom surface of channel 26, the cutter holder 23 continues to fall, causing the cutter 231 to cut the rubber at the notch 21, cutting off a small piece of rubber. Then, the cutter holder 23 rises, and when its top surface contacts the bottom surface of the pressure plate 24, it rises along with the rubber. The pressure plate 241 then detaches from the rubber, and the belt conveyor 1 continues to run, repeating the above cutting process. Each time, the distance the rubber is conveyed forward is slightly less than the length of the notch 21. Because the cutter 231 is stepped, it can simultaneously cut the portion of the rubber extending beyond the notch 21 in both length and width directions, obtaining multiple small pieces. When the first piece of rubber is almost finished cutting, the second piece of rubber is placed behind it, with the front of the second piece of rubber close to the rear of the first piece of rubber to improve cutting efficiency. This device can cut rubber simultaneously in both length and width directions without the need for separate transverse and longitudinal cutting devices.

[0017] Multiple rollers 261 are rotatably connected to the bottom surface of the channel 26, which reduces the friction between the rubber and the bottom surface of the channel 26.

[0018] The frame 2 is provided with a collecting hopper 22 on the side away from the belt conveyor 1. The collecting hopper 22 is inclined downward from the direction near the gap group (the gaps 21 connected end to end form the gap group) to the direction away from the gap group and the width gradually decreases. The collecting hopper 22 is provided with side guards on both sides and a discharge port is provided on the side away from the gap group. A collection box can be placed below the discharge port to collect the rubber blocks.

[0019] A pressure roller 11 is installed above one end of the belt conveyor 1 near the frame 2. The clockwise direction of the pressure roller 11 is opposite to that of the belt conveyor 1. The pressure roller 11 can be driven by a separate motor, or a meshing gear can be installed at one end of the drive roller of the belt conveyor 1 and one end of the pressure roller 11. The pressure roller 11 presses against the upper surface of the rubber, making it less likely to slip between the pressure roller 1 and the belt conveyor 1.

[0020] Guide posts 232 are provided on both sides of the top surface of the tool holder 23, and guide holes for sliding connection with the guide posts 232 are provided on both sides of the pressure seat 24. This structure realizes the sliding connection between the pressure seat 24 and the tool holder 23. The pressure seat 24 is also provided with a through hole for the piston of the hydraulic cylinder 25 to pass through.

[0021] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
