Description

Technical Field

[0001] The utility model relates to the technical field of rubber production, in particular to a rubber and plastic product cutting device. Background Art

[0002] Rubber products refer to various rubber products produced with natural and synthetic rubber as raw materials, and also include rubber products recycled from waste rubber. The output of synthetic rubber has greatly exceeded that of natural rubber, among which the largest output is styrene-butadiene rubber.

[0003] There are many varieties of rubber and plastic products, which can be divided into static sealing products and dynamic sealing products according to their working status. Some semi-finished rubber and plastic products need to be processed twice, and the cutting device is needed to cut or trim the rubber products to a certain length and size.

[0004] Application No. CN202122689989.X discloses a rubber and plastic product cutting device. Its technical solution includes: a main box body and a motor fixed to the left side of the main box body, the output shaft of the motor passes through the right side of the main box body and is fixedly connected to a reciprocating screw rod, and a reciprocating nut is movably sleeved on the reciprocating screw rod. It has the advantages of being able to automatically cut rubber and plastic products, maintain stability during cutting, and prevent rubber and plastic products from flying off during the cutting process, thereby improving safety.

[0005] In the production of rubber strip cutting, it is often necessary to cut multiple rubber strips of the same length. In order to prevent the rubber strip from swinging left and right during cutting, resulting in an uneven cut surface, the cutting device needs to clamp the rubber strip, and after cutting, the clamp needs to be loosened and the rubber strip needs to be pulled out. The length of the pulled rubber strip also needs to be measured, resulting in low cutting efficiency when preparing multiple rubber strips of equal length. For this reason, we propose a rubber and plastic product cutting device. Utility Model Content

The conveying component is used to drive the rubber strip to be cut and processed to move, thereby exposing the rubber strip of the required cutting length, so as to perform fixed-length multi-section cutting of the rubber strip. The surface of the rubber strip cutting table 1 is constructed with a limiting slide groove 10 and a through groove 11 arranged in parallel, and the internal structure of the rubber strip cutting table 1 is connected to the through groove 11. The cross section of the horizontal slide groove is a transverse T-shaped, and a motor frame 14 and a horizontal sliding block 15 fixed to the side wall of the motor frame 14 are slidably arranged in the horizontal slide groove, and a screw 16 that penetrates the horizontal sliding block 15 is also rotatably arranged in the horizontal slide groove. A reciprocating motor 17 for driving the screw 16 to rotate clockwise or counterclockwise is installed at the end of the rubber strip cutting table 1, a cutting motor is installed inside the motor frame 14, and a cutting blade 18 located in the through groove 11 is fixedly installed at the end of the output shaft of the cutting motor, and a rubber strip end clamping component is arranged in the limiting slide groove 10. The rubber strip end clamping component is used to limit and press the cutting end of the rubber strip to prevent the rubber strip end from swinging left and right during cutting and affecting the cutting effect. A protective frame 19 is fixed to the bottom of the rubber strip cutting table 1, and the protective frame 19 is arranged on the bottom periphery of the cutting blade 18. The protective frame 19 is used to shield the cutting blade 18 from the bottom to prevent safety accidents.

[0027] In order to facilitate the horizontal movement of the rubber strip to expose the rubber strip of the required length, the conveying component includes a vertical plate 5 horizontally arranged on the inner side of the top frame 2, a top frame 4 is fixed between the tops of the vertical plates 5, and the top frame 4 is fixed to the bottom of the lifting hydraulic cylinder 3, and a number of equally spaced conveying rollers 6 are rotatably arranged between the side walls of the vertical plates 5. The number of conveying rollers 6 is consistent with the number of rotating rollers 9, and the conveying rollers 6 are arranged directly above the rotating rollers 9. The side walls of the top frame 4 are installed with reduction motors 7 for driving the rotating shafts of the edge side conveying rollers 6 to rotate, and the rotating shafts of adjacent conveying rollers 6 are connected in turn by belts and pulleys. According to the needs of use, an external controller and circuit board can be connected to realize precise control of the rubber strip conveying distance by controlling the number of rotations of the reduction motor 7.

[0028] In order to facilitate the rapid tightening of the rubber strip and avoid excessive squeezing of the rubber strip so that the rubber strip cannot be moved and transported through the conveying component, the clamping component at the end of the rubber strip includes a penetrating rod 13 inserted and fixed in the limiting slide groove 10, and the penetrating rod 13 is penetrated by a limiting slider 12 symmetrically and slidably arranged in the limiting slide groove 10, a clamping plate 20 is fixed on the top of the limiting slider 12, and a rubber sheet 21 is bonded to the side wall of the clamping plate 20, the side of the clamping plate 20 close to the cutting blade 18 is flush with the side of the cutting blade 18 close to the clamping plate 20, and the outer periphery of the penetrating rod 13 is sleeved with a spring located on the side away from the limiting block, and a spring with a suitable elastic coefficient is selected to avoid excessive squeezing of the rubber strip by the clamping plate 20 so that the rubber strip cannot move after clamping, and to avoid the inability to stably clamp the rubber strip.

[0029] It should be noted that the utility model is a rubber and plastic product cutting device. When in use, the rubber strip to be cut is placed on the surface of the rotating roller 9, and then the lifting hydraulic cylinder 3 is extended to drive the conveying component to descend, thereby placing the rubber strip between the rotating roller 9 and the conveying roller 6, and the clamping plate 20 is moved to both sides and then the reduction motor 7 is started. The output shaft of the reduction motor 7 drives multiple rotating rollers 9 to rotate in the same direction at the same time through the belt and the pulley, and the rubber strip is moved to the side of the cutting blade 18 until the end of the rubber strip passes through the clamping plate 20. When the exposed part of the rubber strip is adapted to the required size, it is then disconnected. The reduction motor 7 is powered and the reciprocating motor 17 is started. The reciprocating motor 17 drives the screw 16 and the horizontal sliding block 15 to rotate relative to each other, so that the motor frame 14 slides horizontally in the horizontal sliding groove. The cutting blade 18 that moves therewith rotates at high speed under the action of the cutting motor, and moves to the edge side of the fitting splint 20 to cut off the exposed rubber strip. When one end of the rubber strip is cut off, the power of the reciprocating motor 17 and the cutting motor is disconnected, and then the reduction motor 7 is started to move the rubber strip for a distance, and then the reciprocating motor 17 and the cutting motor are started again, and this is repeated continuously to cut the rubber strip into multiple sections.
