Technical Field

[0001] This utility model relates to the field of industrial belt production, and in particular to an industrial belt trimming device. Background Technology

[0002] Industrial belts are generally manufactured using a thermoforming process, which involves extruding molten rubber through a mold. During this extrusion process, excess rubber forms burrs around the belt, necessitating trimming at the edges to achieve the desired finish. The common cleaning method involves hand-held cutting devices, which is inefficient and generates dust during the cutting process. This dusty environment negatively impacts worker health and causes environmental pollution. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0016] Reference Figure 1-2An industrial belt trimming device includes a traction and winding assembly 1 and a cutting assembly 2 mounted on a workbench. The cutting assembly 2 includes a clamping part 21 and a cutting part 22. A gap is provided between the clamping part 21 and the workbench for the belt to pass through. When the belt passes through the gap, the clamping part 21 abuts against the surface of the belt. The edge of the newly formed belt is clamped by the clamping part 21, but it can be pulled by the traction and winding assembly 1. The belt can be pulled and wound up simultaneously with the clamping. This allows the belt to pass through the cutting part 22 in sequence, and then be cut using the traction force of the traction and winding assembly 1 when passing through the cutting part 22. This completes both the belt trimming and the belt winding work. The cutting process generates virtually no dust and greatly speeds up the belt trimming efficiency.

[0017] The traction winding assembly 1 in this embodiment includes a winding roller 11 and a traction belt 12. A support frame 13 is erected on the workbench for mounting the traction winding assembly 1. One end of the traction belt 12 is fixed to the winding roller 11, and the other end of the traction belt 12 is detachably fixed to the end of the belt. The winding roller 11 is rotatably connected to the support frame 13, and a motor is provided on the support frame 13 for driving the winding roller 11 to rotate.

[0018] Specifically, the cutting part 22 is located at the end of the clamping part 21, and the traction winding assembly 1 is located on the worktable for pulling the belt through the gap. When the clamping part 21 is pressed down, the end of the cutting part 22 contacts the worktable, and the cutting edge 221 of the cutting part 22 faces the belt. When the belt moves, the cutting edge 221 is used to cut the edge of the belt. In actual use, the boundary to be cut can be determined by changing the position of the clamping part 21. That is, the boundary to be cut is actually determined by the clamping part 21, so that the belt trimming can be achieved.

[0019] Correspondingly, in this embodiment, a support frame 13 is fixed on the end face of the workbench for mounting the clamping part 21. The clamping part 21 includes a clamping plate 211 and a clamping drive cylinder 212. The clamping drive cylinder 212 is fixed on the support frame 13 and positioned above the workbench. The clamping plate 211 is fixed on the push shaft of the clamping drive cylinder 212. The clamping drive cylinder 212 drives the clamping plate 211 to move towards the workbench and press against it. A rotating wheel 213 is provided on the end face of the clamping plate 211 facing the belt. When the winding assembly 1 pulls the belt, the belt drives the rotating wheel 213 to rotate. The surface of the rotating wheel 213 can be covered with rubber to increase the friction between the belt and the rotating wheel 213 and reduce the possibility of belt deviation during movement, resulting in more precise trimming.

[0020] The cutting section 22 includes a cutting seat 222, which is disposed on the side wall of the pressure plate 211 and positioned between the traction winding assembly 1 and the pressure plate 211. The cutting seat 222 has a cutting edge 221 on the side facing the pressure plate 211. The pressure plate 211 has a pair of limiting ears on its side wall, and a sliding shaft 225 passes between the pair of limiting ears. The cutting seat 222 has a through hole 223, and is sleeved onto the sliding shaft 225 through the through hole 223. A compression spring 224 is provided between the upper end face of the cutting seat 222 and the ear plates. When the pressure plate 211 presses the belt, the cutting seat 222 contacts the worktable and pushes the compression spring 224 to compress. In this embodiment, there is a pair of pressure plates 211, which can press against the edges on both sides of the belt. Each pressure plate 211 is matched with a set of cutting seats 222. In the initial state, the lower end face of the cutting seat 222 is slightly lower than the clamping plate 211. When pressed down, the cutting seat 222 first contacts the worktable, and then the clamping plate 211 presses against the belt. The compression spring 224 provides a reverse pressure after being compressed, so that the cutting seat 222 can fit tightly against the worktable. This enables the cutting of the belt edge.

[0021] In this embodiment, the cutting seat 222 is L-shaped, and the through hole 223 is opened on the long side of the cutting seat 222. The short side of the cutting seat 222 is perpendicular to the long side of the cutting seat 222 and extends towards the workbench. The end of the short side of the cutting seat 222 is lower than the lower end face of the clamping plate 211, and the cutting edge 221 is provided on the short side.

[0022] Compared to existing technologies, this invention allows for direct traction of the belt after it has been formed by the take-up roller 11. During traction, the untrimmed belt passes under the pressure plate 211 of this device. The pressure plate 211 then presses down on the edge of the belt, which, during its movement, passes sequentially through the cutting edge 221 for trimming. This trimming process generates virtually no dust and significantly accelerates the efficiency of belt trimming.

[0023] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
