Description

Technical Field

[0002] Rubber sheet is a sheet product with a certain thickness and a large area made of rubber as the main material through vulcanization. It is referred to as rubber sheet. Rubber sheet is made of mixed rubber through calendering, laminating or extrusion, and vulcanized with a flat vulcanizer or continuously vulcanized with a drum vulcanizer.

[0003] For example, a rubber product cutting device with publication number CN219854850U generates an outward lateral force and a downward pressure on the bottom plate through a mounting plate and a rotating plate, and fixes the rubber product under the pressure to facilitate cutting. Under the action of the outward lateral force, the two bottom plates are moved away from each other and a pulling force is generated on both ends of the rubber product to straighten the rubber product and improve the cutting accuracy. However, in the process of cutting the rubber sheet, the rubber sheet is mainly broken by the downward pressure of the cutting knife. The main pressure of the cutting knife is concentrated on the middle part of the mounting plate during the cutting process, and the cutting force on the rubber sheet is not uniform. As a highly elastic material, the rubber sheet may encounter greater resistance when directly cut, which affects the flatness of the cut portion of the rubber sheet and increases the wear of the cutting knife. Moreover, if the cutting knife is not replaced in time after long-term use, the cutting knife will become blunt, which will affect the cutting quality of the rubber sheet and has certain use defects.

[0022] By adopting the above technical solution, it is convenient for users to limit the adjustment rod, thereby facilitating the adjustment of the angle of the rubber plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: when the cutting device for processing rubber products with an adjustment mechanism is cutting the rubber sheet, the cutter can move back and forth during the downward movement, so that the cutter moves back and forth to cut the rubber sheet, and the back and forth movement for cutting can apply the cutting force more evenly, avoiding the uneven force on the cutter affecting the cutting effect, and the reciprocating cutting of the cutter can disperse the cutting force, so that the impact and wear of the cutter during the cutting process will be reduced accordingly, thereby extending the service life of the cutter and helping to improve the cutting quality and cutting effect; 1. A cutting assembly is arranged in the middle of the workbench. When the rubber sheet is cut, the rubber sheet is positioned by adjusting the assembly, and the hydraulic push rod is started to drive the movable plate to move downward. During the downward movement of the movable plate, the guide rod slides on the mounting plate. During the downward movement of the movable plate, the rotating gear can be driven to move. The engagement of the rotating gear and the rack can drive the rotating shaft to rotate. After the rotating shaft rotates, the first pulley can be driven to rotate. The first pulley can drive the rotating rod to rotate rapidly through the cooperation with the second pulley, thereby making the two cams rotate synchronously in opposite directions. After the cam rotates, the mounting seat can be pushed to reciprocate through the sliding connection with the push plate. During the movement, the positioning sleeve of the mounting seat slides on the cross plate to limit the position, and during the downward movement of the movable plate, the roller and the rubber The rubber plate contacts, and the movable plate continues to descend, so that the roller shaft rotates on the rubber plate, and drives the rotating plate to rotate on the mounting frame, driving the torsion spring to deform. Under the action of the damping bearing, the roller shaft rotates to flatten the rubber plate, which is convenient for subsequent cutting. The rubber plate is cut by the reciprocating movement of the cutter. When the rubber plate is cut, the cutter can move back and forth during the downward movement through the cutting assembly, so that the cutter reciprocates to cut the rubber plate. The back and forth movement cutting can apply the cutting force more evenly, avoiding the uneven force on the cutter affecting the cutting effect. If the cutter reciprocates to cut, the cutting force can be dispersed, so that the impact and wear of the cutter during the cutting process will be reduced accordingly, thereby extending the service life of the cutter and helping to improve the cutting quality and cutting effect; 2. After the cutter has finished cutting the rubber sheet, it continues to drive the movable plate downward, so that the cutter continues to move downward, and sandpaper is attached to the two inclined plates, so that the cutter can contact the inclined plates. The continued movement of the cutter can be close to the inclined plates, and the inclined plates are pushed to drive the sliding rod to slide in the sliding groove, so that the telescopic spring can be stretched, and the cutter reciprocates on one side of the inclined plate. The cutter can be polished by sandpaper to ensure the sharpness of the cutter, thereby increasing the service life of the cutter; 3. Adjustment components are symmetrically arranged on both sides of the top of the workbench. When cutting the rubber sheet, the two hand wheels can be turned to drive the screw rod to rotate. The screw rod rotates and moves through the threaded connection with the support frame. After the rubber sheet is fixed, the pull rod can be pulled to drive the movable rod to slide on the support block according to the cutting requirements. The reset spring can be stretched to drive the card teeth on the arc sleeve to leave the limit gear, so that the adjusting rod loses the limit. The positioning plate can be rotated to drive the adjusting rod to rotate on the U-shaped plate. The position of the pointer on the scale line can be observed to adjust the angle of the positioning plate. After adjustment, the pull rod is released. Under the action of the reset spring, the card teeth on the arc sleeve are stuck between the teeth of the limit gear, and the reset spring is in a stretched state, which can prevent the adjusting rod from rotating, and then the rubber sheet can be placed between the two positioning plates. The cutting position of the rubber sheet can be adjusted through the adjustment component to improve the overall applicability. BRIEF DESCRIPTION OF THE DRAWINGS

When cutting the rubber sheet, the two hand wheels 304 can be turned to drive the screw rod 302 to rotate. The screw rod 302 rotates and moves through the threaded connection with the support frame 301. After the rubber sheet is fixed, the pull rod 315 can be pulled to drive the movable rod 310 to slide on the support block 309.

[0033] Working principle: When using the cutting device for rubber products processing with an adjustment mechanism, first, Figure 1-Figure 9As shown, the two hand wheels 304 are rotated to drive the screw rod 302 to rotate. The screw rod 302 rotates and moves through the threaded connection with the support frame 301. After the rubber plate is fixed, the pull rod 315 can be pulled to drive the movable rod 310 to slide on the support block 309.

The positioning plate 307 can be rotated to drive the adjustment rod 305 to rotate on the U-shaped plate 303. The position of the pointer 308 on the scale line can be observed to adjust the angle of the positioning plate 307. After adjustment, the pull rod 315 is released and the reset spring is released. Under the action of the spring 314, the latching tooth 312 on the arc sleeve 311 is stuck between the teeth of the limiting gear 313, and the reset spring 314 is in a stretched state, which can prevent the adjustment rod 305 from rotating, and then the rubber plate can be placed between the two positioning plates 307, and the hydraulic push rod 203 is started to drive the movable plate 204 to move downward.

After the cam 219 rotates, it can push the mounting seat 209 to move back and forth through the sliding connection with the push plate 2091. During the movement of the mounting seat 209, the positioning sleeve 208 slides on the cross plate 207 to limit the position, and the movable plate 204 makes the roller shaft 222 contact with the rubber plate during the downward movement. The movable plate 204 continues to descend to make the roller shaft 222 rotate on the rubber plate, and drives the rotating plate 221 to rotate on the mounting frame 220, driving the torsion spring 2211 to deform, and under the action of the damping bearing, the roller shaft 222 rotates. The rubber sheet can be stretched flat to facilitate subsequent cutting. The rubber sheet is cut by the reciprocating movement of the cutter 210. After the cutter 210 completes cutting of the rubber sheet, it continues to drive the movable plate 204 downward, so that the cutter 210 continues to move downward, and sandpaper is adhered to the two inclined plates 224. The cutter 210 can contact the inclined plates 224. The continued movement of the cutter 210 can be close to the inclined plates 224, pushing the inclined plates 224 to drive the sliding rod 225 to slide in the sliding groove 226, so that the telescopic spring 228 can be stretched, and the cutter 210 reciprocates on one side of the inclined plate 224.
