Description

Technical Field

[0001] This utility model relates to the technical field of cutting mechanisms and shearing devices for processing rubber products, specifically a cutting mechanism and shearing device for processing rubber products. Background Technology

[0002] In the field of rubber product manufacturing, rubber materials are widely used. With industrial development and the increasing market demand for rubber products, higher requirements are placed on the efficiency and quality of rubber product processing. Among them, the shearing process, as one of the key links in the rubber product processing process, directly affects the processing quality of the product.

[0003] The existing solution, CN219027658U, discloses a rubber product shearing device that uses a moving mechanism to move the cutting mechanism and an adjusting mechanism to adjust the height of the cutting mechanism. When the friction-reducing mechanism comes into contact with the rubber, the cutting mechanism can cut the rubber. The pressure plate can move with the movement of the cutting mechanism, that is, it always fixes the area to be cut by the cutting mechanism. This can fix soft rubber sheets and facilitate the operation of workers. However, after long-term use, the blades are not convenient for later maintenance and replacement. Utility Model Content

[0024] 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.

[0025] Please see the appendix Figure 1-6 This application provides the following technical solutions.

[0026] Example 1

[0027] A cutting mechanism includes a workbench 1, with a U-shaped support 2 at the upper end of the workbench 1. A threaded rod 202 is horizontally inserted through the U-shaped support 2 via a bearing. A slider 203 is movably connected to the threaded rod 202. Two lead screws 204 and two telescopic columns 205 are symmetrically arranged at the lower end of the slider 203. A module 206 is fixedly installed at the end of the telescopic column 205 away from the slider 203. The ends of the lead screws 204 away from the slider 203 are connected to the module 206 via lead screw sleeves. A sliding groove 209 is formed inside the module 206, and a cutting tool is slidably inserted into the sliding groove 209. The mounting assembly includes a hinge cover 211 and a cutting blade 213. The hinge cover 211 is movably connected to a support plate 212 via a hinge shaft. The support plate 212 has a through-hole for the cutting blade, and slots are provided on both sides of the through-hole. The cutting blade 213 is inserted through the through-hole. The upper end of the cutting blade 213 has locking blocks on both sides, which are located in the slots. The size of the cutting blade 213 is adapted to the size of the slot. The upper end of the cutting blade 213 abuts against the lower end of the hinge cover 211. The cutting blade 213 is stable and reliable after installation, and the design of the locking blocks ensures that the cutting blade 213 will not fall off.

[0028] Module 206 can move left and right via slider 203. The cutting blade 213 descends under the control of lead screw 204 and can perform horizontal cutting when it comes into contact with the rubber product to be processed. The hinge cover 211 and the bearing plate 212 are inserted into the sliding groove 209, and the stable fit ensures stability and reliability.

[0029] A limiting component is provided inside module 206. The limiting component includes a baffle 210. One side of the baffle 210 abuts against the hinge cover 211 and the support plate 212. A groove 208 is vertically provided in the sliding groove (209) on one side of the module 206. Limiting grooves 207 are symmetrically provided on both sides of the groove 208. One side of the baffle 210 is movably inserted into the groove 208. Anti-detachment blocks 215 are symmetrically provided on both sides of the baffle 210 in the groove 208. The two anti-detachment blocks 215 are movably inserted into the two limiting grooves 207 respectively. Thus, the baffle 210 can be prevented from falling off because the anti-detachment blocks 215 move up and down along the trajectory in the limiting grooves 207.

[0030] The sides of the baffle 210 that contact the hinge cover 211 and the support plate 212 are all inclined. A spring groove is formed inside the inclined surface of the baffle 210, and a limit pin 214 is horizontally inserted through the spring groove. A spring 216 is sleeved on the circumferential surface of the limit pin 214. A push plate is provided on one side of the limit pin 214 near the spring 216. A slot is formed inside the hinge cover 211 near the baffle 210, and the limit pin 214 passes through one end of the baffle 210. The side-mounted slot, hinge cover 211 and support plate 212 slide along sliding groove 209 to the bottom, press down baffle 210, the limiting pin 214 inside baffle 210 is engaged in the slot inside hinge cover 211, during which the inclined surface on one side of baffle 210 abuts against the inclined surface of hinge cover 211, so that baffle 210 presses the hinge cover 211 and support plate 212 toward the other side of sliding groove 209 during the pressing process, thereby keeping the entire tool mounting assembly more stable.

[0031] A rubber product processing shearing device, which has a cutting mechanism.
