[0018] 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.

[0019] Please see Figures 1-7 This utility model proposes an automatic hot cutting device for plastic rolls, including an operating table 1, a slide groove 11 on the operating table 1, a hot cutting mechanism 2 and a conveying roller 4 on the outer wall of the operating table 1, a conveyor belt 3 below the hot cutting mechanism 2, and a traction device on the operating table 1.

[0020] In an embodiment of this utility model, in order to traction the roll material, the traction device specifically includes a second screw 51, which passes through and is slidably connected to the moving rod 52. A rod body 522 is connected to the outer wall of the moving rod 52. The rod body 522 passes through and is slidably connected to the pressing rod 26. A return spring is provided between the pressing rod 26 and the outer wall of the moving rod 52. The moving rod 52 is slidably connected to the slide groove 11. The moving rod 52 has a through groove 521. An L-shaped rod 54 is slidably connected to the through groove 521. The L-shaped rod 54 passes through and is slidably connected to the moving rod 52. A pressure plate 53 is connected to the end of the L-shaped rod 54. A rubber pad 531 is connected to the outer wall of the pressure plate 53. A limit block 541 is connected to the outer wall of the L-shaped rod 54. An elastic rod 55 passes through and is slidably connected to the moving rod 52. A locking block 551 is connected to the outer wall of the elastic rod 55. Furthermore, the hot cutting mechanism 2 includes a support plate 21, with an inclined block 20 connected to the outer wall of the support plate 21. A pressing rod 26 is provided inside the support plate 21. The pressing rod 26 is driven by an electric cylinder. A base plate 22 is provided below the pressing rod 26. The base plate 22 has a notch 221. The support plate 21 is penetrated by a screw 23 and is rotatably connected to the screw 23. The screw 23 is fitted with a threaded block, and a hot cutting blade 24 is connected to the outer wall of the threaded block. The threaded block is penetrated by a guide rod 25 and is slidably connected to the guide rod 25. Furthermore, the outer wall of the operating table 1 is connected to a side plate 12, the side plate 12 is provided with a sliding groove 13, the outer wall of the side plate 12 is provided with a scale line 14, the sliding groove 13 is slidably connected to a protrusion 15, the protrusion 15 is penetrated by a screwing block 17 and is threadedly connected to the screwing block 17, and a pointer 16 is connected to the outer wall of the protrusion 15. In this invention, during use, the roll material on the conveyor roller 4 is first pulled to the outer surface of the base plate 22, and then the motor is started to drive the screw 51 to rotate. Under the transmission action of the screw 51, the moving rod 52 moves towards the hot cutting mechanism 2; when the moving rod 52 is about to approach the support plate 21, the inclined plate 20 will contact the L-shaped rod 54 and generate compression, forcing the L-shaped rod 54 to move downward.

[0021] When the L-shaped rod 54 moves downward, the pressure plate 53, which is fixedly connected to it, moves downward synchronously, and the return spring is compressed and undergoes elastic deformation. When the moving rod 52 aligns with the notch 221, the limiting block 541 on the outer wall of the L-shaped rod 54 will squeeze the locking block 551, causing the elastic rod 55 to contract inward into the moving rod 52, and its internal spring deforms accordingly. After the squeezing force of the limiting block 541 on the locking block 551 disappears, the locking block 551 will spring into the limiting block 541 under the action of the spring force, thereby limiting and fixing the pressure plate 53. At this time, the pressure plate 53 and the moving rod 52 cooperate to firmly clamp the roll material.

[0022] Next, control motor one to rotate in the opposite direction, driving the moving rod 52 to move in the opposite direction, pulling the roll material to the specified position, and then turn off the motor. Then start the hydraulic cylinder to push the pressing rod 26 to move upward, compacting the roll material; then start motor two to drive screw one 23 to rotate, and through the transmission action of the threaded block, make the hot cutting blade 24 move along the direction of screw one 23 to complete the hot cutting process of the roll material; After the heat cutting process is completed, motor 1 is restarted to drive the moving rod 52 to continue moving away from the heat cutting mechanism 2. During the movement of the moving rod 52, the elastic rod 55 on its side wall will contact the protrusion 15 on the equipment frame. The protrusion 15 will apply a squeezing force to the elastic rod 55, forcing the elastic rod 55 to retract into the moving rod 52 again, thereby causing the locking block 551 to disengage from the limiting block 541.

[0023] At this point, the limiting constraint on the pressure plate 53 is released, and it will move upward back to its initial position under the elastic force of the return spring, thereby releasing the clamping and fixing of the roll material. Then, the conveyor belt 3 is started. When the conveyor belt 3 is running, it will drive the hot-cut roll material forward and transport it to the next process, completing the connection between the entire hot-cutting process and the conveying process.

[0024] It should be noted that the protrusion 15 and the sliding groove 13 of the equipment frame adopt a sliding connection structure. The operator can push the protrusion 15 along the sliding groove 13 according to the required hot cutting length of the roll material and adjust its position on the side plate 12. After the position is determined, simply tighten the screwing block 17 on the side of the protrusion 15 to firmly fix the protrusion 15 in the sliding groove 13 through friction, ensuring the stability of the position when the elastic rod 55 is squeezed later.

[0025] Meanwhile, the outer wall of the side plate 12 of the equipment is marked with clear scale lines 14. When adjusting the position of the two sets of protrusions 15, the values ​​can be read by referring to the scale lines 14, so that the two sets of protrusions 15 are aligned with the same scale and are on the same horizontal line. This avoids uneven force on the elastic rods 55 on both sides due to the deviation of the protrusion position, thereby ensuring that the pressure plate 53 is released from clamping at the same time, and improving the stability of equipment operation and the accuracy of roll material processing.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
