Description

Technical Field

[0001] The invention relates to a cutting device for rubber sheet strips used in tire manufacturing, in particular to a multi-blade framing cutting machine for thin rubber sheet strips. Background Art

[0002] The rubber manufacturer calenders the wide and long rubber and PE lining together to form a wide thin tape, and uses a rotating reel to wind the wide thin tape into a roll, which is then provided to the tire manufacturer for the manufacture of green tires; however, in the actual production of tires, the tire manufacturer needs to cut the wide thin tape roll obtained from the rubber manufacturer longitudinally into several small (narrow) width thin rubber tape reels to meet the actual production needs.

[0003] For example, a multi-knife longitudinal cutting machine disclosed in the Chinese utility model patent (CN2625124Y) has a surplus material collecting device 5, a rolling cutting device 3 and a passive winding device 4 on the same chassis, and its rolling cutting device 3 and the passive winding device 4 form an integral linkage device according to the friction contact of the rolling cutting roller 12; its basic working principle is: first, the film roll is placed on the guide square bar 6 and the film is guided by the friction damping wheel, then, after passing through the traction roller 8, the cloth guide roller 9 and the receiving platform 2, it enters the rolling cutting system, the film is closely attached between the cutting knife 20 and the rolling cutting roller 12, the cylinder drives the cutting knife 20 to cut, and the cut rubber strip is wound around the winding core wheel 16 by the friction between the rolling cutting roller 12 and the winding core wheel 16 on the swing arm 15, and finally, the discarded rubber strip edge and the plastic pad after cutting are wound by the collection roller 18 on the surplus material collecting device 5, thereby completing the whole process from guiding → cutting → winding → surplus material processing. The main problems of the above-mentioned multi-blade longitudinal cutting machine are as follows: ① The disadvantages of the cutting → winding → waste material processing device being assembled into one: ⅰ. The waste material collecting device 5 shares the chassis with the rolling cutting device 3 and the passive winding device 4. Although it solves the synchronization of cutting and winding, the collecting roller 18 of the waste material collecting device 5 is located in the limited space below the chain transmission mechanism and the cutter of the frame 19. It is neither safe nor convenient to take the waste material from the collecting roller 18 for reuse; ⅱ. The rubber strip cut by rolling is tightly attached to the rolling cutting roller 12 and The tape is wound around the core wheel 16 passively by the friction between the rolling roller 12 and the winding core wheel 16, so as to control the tightness of the tape wound into a reel; since the circular blade 21 cuts the film into sections, the slits of the two adjacent films are still close to each other, and the films after sectioning are rolled up on the winding core wheel 14 to form reels of tape, and the surfaces of the reels are still tightly adhered together, and are not obviously separated. If the rolled tape wheel is loose, the tape will be pulled to the side and deformed when the two reels are separated, which may cause serious damage. The adhesive tape is loosened from the reel and scattered, tangled into a ball and becomes waste; ⅲ. After the film roll is unwound, it passes through the traction roller 8, the guide roller 9, and the receiving platform 2 before entering the rolling cutting. The film is not flattened and wrinkle-proofed in the width direction, which will cause the wrinkled film to enter the rolling cutting device 3 for cutting, making the edges of the film strips cut by framing uneven. The defective adhesive tape cannot be used to produce tires, causing production waste; ② Since the rolling cutting device 3, the passive winding device 4, and the winding core wheel 16 share the rolling cutting roller 12, the rolling cutting device As soon as the film strip cut by device 3 is cut, it is guided to the passive winding device 4 for winding by the winding core wheel 16 in a loose and tight manner. Since the distance between the three is very close, once a defective product with uneven edges of the cut film strip appears, it cannot be found by the naked eye; that is, the cause of the defective product cannot be seen at a glance from the running equipment, and the equipment cannot be stopped and repaired in the first time to eliminate the fault; ③ It can only cut out rubber strips with a width of more than 40 mm, while tire production often requires the use of tape strips with a width of less than 40 mm.

The width-fixing tape guide roller 54 of the present invention is provided with a plurality of slip rings 541 for limiting the width of the framing tape 101 at intervals, and each slip ring 541 is radially mounted with a tightening screw 542 for tightening the width-fixing tape guide roller 54 to position and fix the slip ring 541. By sliding left and right to adjust the spacing between adjacent slip rings 541, and locking and fixing them with the tightening screw 542, the spacing between adjacent slip rings 541 can be set to match the width of the limited framing tape 101, so that the width-fixing tape guide roller 54 can flatten a plurality of framing tapes 101 and limit the guiding direction. The groove bottom countersunk hole of the width-fixing guide groove plate 56 of the present invention is installed with the anchor screw 561 which is anchored and locked on the straight groove rail B; the groove width of the width-fixing guide groove plate 56 is selected to correspond to and be equal to the spacing between the two slip rings 541 on the width-fixing tape guide roller 54 corresponding to the front thereof, and the width-fixing guide groove plate 56 can slide left and right on the straight groove rail B to adjust the position, and is locked and fixed by the anchor screw 561. The above-mentioned slit tape rollers 53, slip rings 541 and fixed width guide groove plates 56 are all located on the equipment at a position convenient for manual adjustment, and the working status of the slit tape 101 after slit separation, leveling and limiting transmission and fixed width guiding can be checked by the naked eye; once there is a problem with the quality of the slit tape 101 cut by the width guide cutting machine 10, or there is a problem in the process of winding up the slit tape 101, the root cause of the problem can be found immediately, and the machine can be stopped to eliminate it, so as to ensure the production quality of the tape slit cutting and winding.
