Description

High-efficiency rubber strip opening machine

technical field

The utility model relates to a slitting cutting for materials such as rubber, leather, and soft materials. It is especially suitable for cutting rubber strips with different widths after rubber mixing, and is the necessary equipment for vulcanizing machines before vulcanization and molding.

Background technique

Traditionally used slitting machines for cutting soft materials such as rubber are all straight cutting. The straight cutting knife fixed on the beam of the gantry reciprocates up and down to cut the strips. Since the straight cutting knife cannot be made very long, its The length of the cutting strip is limited by the length of the blade; in addition, due to the strong adhesion between soft materials such as rubber and the smooth blade surface, the cut film will be lifted up, which directly affects the production efficiency and cutting quality.

Contents of the invention

The purpose of the utility model is to provide a high-efficiency rubber material stripping machine capable of cutting multiple strips of any desired length at one time.

The utility model high-efficiency rubber strip opening machine mainly includes a feed table, a discharge table, parallel main cutter shafts and auxiliary cutter shafts. The two shafts are synchronously reversed by gear meshing. The sleeve constitutes the main knife roller, and the rotary knife ring and the shaft sleeve are set at intervals on the auxiliary knife shaft to form the auxiliary knife roller. The motor is connected with the main knife shaft or the auxiliary knife shaft through a transmission device. The rotary cutter rings are interleaved to form a rotary shearing mechanism, and the intervals between the rotary blades correspond to the intervals between the rotary cutter rings.

The above-mentioned feeding platform is composed of a platform frame and its supporting frame, and a plurality of rollers parallel to the main knife roller are arranged in the platform frame.

The rollers of the feed table and the discharge table are made of stainless steel. There is a stainless steel transition platform between the rollers and the feed ports of the main and auxiliary knife rollers, and the discharge table is inclined downward.

Above-mentioned transmission device is made up of driving sprocket, driven sprocket and the chain between them.

A baffle is fixed at the frame position behind the main cutter roller, and the front end of the baffle extends to the rear lower side of the rotating blade of the main cutter roller.

The above-mentioned rotary blade is made into a single sharp edge surface, and the lower end of the flat edge surface of the knife tip is flatly attached to one side of the rotary knife ring on the auxiliary knife roller.

The rotary blade and the rotary knife ring of the utility model are interleaved to form a rotary shearing mechanism, which can clamp the film and cut it into rubber strips of any length, which can replace many people's heavy hand-cut strips, reduce labor intensity, and open The strips are uniform and accurate. If you replace the bushings with different heights, you can cut a variety of strips with different widths at the same time. For example, if the distance between the blades is adjusted to 30, 40, and 50mm, the width can be 30, 40, and 50mm. The length is not limited. The rubber strip; the baffle plate device can prevent the rubber strip from following the knife; the feed table roller, transition platform and discharge table made of stainless steel can reduce friction, not stick glue, and improve production efficiency.

Detailed ways

With reference to accompanying drawing, electric motor 3 is contained in the frame 6, drives driving sprocket 4 after decelerating by cycloid reduction mechanism, and sprocket 4 drives driven sprocket 14 to rotate through short-pitch roller chain 5, and driven sprocket 14 Drive the auxiliary cutter shaft 16 to rotate, and the driving gear 22 fixed on the right end of the auxiliary cutter shaft 16 meshes with the driven gear 21 fixed on the right end of the main cutter shaft 17 to form a synchronous reverse rotation structure of the main cutter shaft 17 and the auxiliary cutter shaft 16. Clamp the film and move it backwards. A flat key 13 is respectively provided between the sprocket 4 and the sprocket 14 and their shafts. On the main cutter shaft 17, the rotating blade 8 and the shaft sleeve 7 are set at intervals to form the main cutter roller. On the auxiliary cutter shaft 16, the rotating cutter ring 11 and the bushing 10 are arranged at intervals to form the auxiliary cutter roller. The position between the rotating blade 8 and the rotating cutter ring 11 is One-to-one correspondence, the rotary blade 8 is made into a single edge surface, and the lower end of the flat edge surface of the knife tip slightly extends into the space between the rotary knife ring 11 and the bushing 10, and is intersected with the 8 rotary knife ring 11 side planes to form a joint Rotary shear mechanism. The feeding table is composed of a stainless steel table frame 24 and its support frame 25. A plurality of stainless steel rollers 23 parallel to the main cutter roller are arranged in the table frame 24, and stainless steel rollers are arranged between the rollers 23 and the feeding ports of the main and auxiliary cutter rollers. The transition platform 29, when the film is clamped by the main knife roller and the auxiliary knife roller, the subsequent film is smoothly moved backward along the rollers 23 and the transition platform 29, and the cut rubber strip slides from the downwardly inclined discharge platform 33 to Finished container. Because the rubber product is relatively sticky, in order to prevent the rubber strip from following the knife, a bar plate 30 is fixed at the frame position behind the main knife roller according to the interval of the rotating knife ring 11, and the front end of the bar plate 30 extends behind the rotary blade 8 of the main knife roller the lower side to scrape off the rubber strip of the heel knife.

Main cutter shaft 17 two ends adopt self-aligning bearing, and wherein one end bearing adopts tapered hole, easy dismounting. In order to adapt to the cutting of films of different thicknesses, a left distance adjustment 18 and a right distance adjustment 20 are respectively installed at the two ends of the main cutter shaft 17 to adjust the distance between the main cutter shaft 17 and the auxiliary cutter shaft 16 .
