Description

Technical Field

[0001] The utility model relates to the technical field of ethylene-propylene rubber processing, in particular to a rubber cutting device for ethylene-propylene rubber processing. Background Art

[0002] Ethylene-propylene rubber is a synthetic rubber with ethylene and propylene as the main monomers. According to the different monomer compositions in the molecular chain, there are EPDM rubber and EPDM rubber. The former is a copolymer of ethylene and propylene, and the latter is a copolymer of ethylene, propylene and a small amount of a third non-conjugated diene monomer. The two are collectively referred to as EPDM rubber, which is widely used in automotive parts, waterproof materials for construction, wire and cable sheaths, heat-resistant hoses, tapes, automotive seals, lubricant additives and other products.

[0003] After searching, the applicant found that a Chinese patent disclosed "a rubber cutting device for rubber processing", and its publication (announcement) number is "CN218837855U". The patent mainly sets a collection mechanism. The movable seat moves downward to drive the cutting knife to cut the rubber strip. If the rubber block pops out, the baffle will block the rubber block to prevent it from popping out. At the same time, the rubber block falls into the collection box along the baffle for collection. When the movable seat moves upward, the movable seat contacts the displacement block, driving the rotating block to rotate. The rotation of the rotating block drives the rotating plate to rotate.

[0025] like Figure 1 and Figure 3 As shown, the adjustment component 3 includes two slide grooves 301 opened on the top surface of the support frame 1 and adjustment grooves 304 opened on both sides of the surface of the support frame 1, the inner walls of the two slide grooves 301 are slidably connected with sliders 302, the top surfaces of the two sliders 302 are commonly fixedly connected with a baffle 303, the opposite sides of the two sliders 302 are fixedly connected with fastening bolts 306, the opposite ends of the two fastening bolts 306 pass through the corresponding two adjustment grooves 304 respectively, and the opposite ends of the two fastening bolts 306 are threadedly connected with fastening nuts 307, and scale lines 305 are provided on both sides of the surface of the support frame 1. The scale lines 305 make it easy to see the position of the baffle 303, so as to facilitate the adjustment of the length of the rubber cutting.

[0026] like Figure 1 and Figure 2As shown, the fixing assembly 2 includes a fixing box 202 and four moving holes 206 opened on both sides of the top surface of the moving box 12. The upper end of the outer wall of the fixing box 202 is slidably connected to the inner wall of the moving box 12. Two reset rods 203 are fixedly connected to both sides of the top surface of the fixing box 202. The rod walls of the four reset rods 203 are all sleeved with reset springs 204. The reset springs 204 can return the fixing box 202 to its original position after the cutting is completed. The rod walls at the top of the four reset rods 203 are respectively slidably connected to the inner walls of the four moving holes 206. A knife groove 201 is opened inside the fixing box 202. The knife groove 201 can facilitate the cutting knife 9 to cut the rubber after the rubber is fixed.

[0027] like Figure 2 As shown, the limiting assembly 4 includes two limiting grooves 401 opened on opposite sides of the inner wall of the fixed frame 5, the inner walls of the two limiting grooves 401 are slidably connected to the limiting blocks 402, and the two limiting blocks 402 cooperate with the two limiting grooves 401 to support and limit the moving box 12 to ensure that the moving box 12 can remain stable during movement, and the opposite sides of the two limiting blocks 402 are fixedly connected to the opposite sides of the surface of the moving box 12 respectively.

[0028] like Figure 1 and Figure 5 As shown, the size of the knife groove 201 is consistent with the size of the rubber cutting opening 10, and the cutting knife 9 is located directly above the rubber cutting opening 10, so that the cutting knife 9 is convenient for cutting the rubber.

[0029] like Figure 2 As shown, the cross section of the fixed box 202 is T-shaped, and the bottom surface of the raised portion around the top of the fixed box 202 contacts the bottom surface of the inner wall of the moving box 12, thereby preventing the fixed box 202 and the moving box 12 from falling off.

[0030] like Figure 1 As shown, the two scale lines 305 are located directly below the two corresponding adjustment slots 304 , and the two scale lines 305 are consistent in length with the two corresponding adjustment slots 304 , thereby facilitating the adjustment of the baffle 303 to a specified position.

[0031] like Figure 2 and Figure 4 As shown, the four moving holes 206 are evenly distributed on both sides of the top surface of the moving box 12 and correspond one-to-one to the four reset rods 203, thereby ensuring that the fixed box 202 does not deviate when it is extended and retracted in the moving box 12.

[0032] Working principle of the utility model: when the rubber cutting device is used, first rotate the two fastening nuts 307, and release the restriction of the two sliders 302 by the fastening nuts 307 by loosening the two fastening nuts 307, and then adjust the positions of the two sliders 302 according to the scale lines 305 on both sides of the support frame 1, that is, adjust the position of the baffle 303 on the support frame 1, and then when the baffle 303 is adjusted to the length of the cut as required, fit one end of the rubber to be cut with one side of the baffle 303, and then start the hydraulic rod 6, and then the hydraulic rod 6 drives the moving box 12 to move downward after starting, and at the same time, the cooperation between the two limit blocks 402 and the two limit grooves 401 can ensure that the moving box 12 does not deviate during movement, and then As the movable box 12 moves downward, the bottom of the fixed box 202 first touches the cut rubber, and then the knife groove 201 at the bottom of the fixed box 202 is aligned with the rubber cutting port 10, and fixes the rubber on both sides of the rubber cutting port 10, and then the fixed box 202 remains stationary, and the movable box 12 continues to move downward, thereby moving the cutting knife 9 downward until the rubber is cut. At the same time, after the fixed box 202 fixes the rubber, the four reset rods 203 on the top surface of the fixed box 202 move out of the four movable holes 206 as the movable box 12 moves downward, and at the same time, the reset springs 204 on the four reset rods 203 are compressed, so that after the rubber is cut, the fixed box 202 automatically rebounds and returns to the initial position.
