[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Embodiment 1:

[0026] Please combine Figure 1-4The present embodiment is a rubber strip cutting device for tire production, comprising a box body 1, wherein both sides of the box body 1 are provided with slide grooves for the extension rod 5 to slide, and a switch door is installed on one side of the box body 1. When the cut rubber strips are stacked and collected in the box body 1, the rubber strips can be taken out by opening the switch door, wherein both sides of the inner wall of one side slide groove are provided with vertical grooves for the rack 7 and the piston rod 6 to slide, and the inner wall of the other slide groove is also provided with a vertical groove for the other piston rod 6 to slide. By using the vertical groove, the stability of the rack 7 and the piston rod 6 during movement can be ensured, and a hydraulic rod 2 is installed on the top of the box body 1, and the model of the hydraulic rod 2 is ZYNC35 / 250-YT hydraulic rod. The bottom end of the hydraulic rod 2 is fixedly connected to a connecting plate 3, and a cutting knife 4 is fixedly installed at the bottom of the connecting plate 3. Extension rods 5 are fixedly connected to both sides of the connecting plate 3, and one side of the two extension rods 5 is fixedly connected to the piston rod 6, and one side of one of the extension rods is fixedly connected to the rack 7.

[0027] A discharge plate 8 capable of discharging the cut rubber strips is rotatably connected to the inner side of the box body 1. One side of the top of the discharge plate 8 is rotatably connected to a transmission rod 9 through a connecting piece. One end of the transmission rod 9 is rotatably connected to a U-shaped rod 10. One end of the U-shaped rod 10 is fixedly connected to a transmission gear 11. The intermediate shaft of the transmission gear 11 is rotatably connected to the inner wall of the box body 1. One side of the transmission gear 11 is meshedly connected to a ratchet 12. One side of the ratchet 12 is rotatably connected to a matching wheel 13. The intermediate shaft of the matching wheel 13 is rotatably connected to the inner wall of the box body 1. The inner side of the matching wheel 13 is rotatably connected to a pawl. The surface of the pawl abuts against a spring sheet installed on the surface of the matching wheel 13. The matching wheel 13 meshes with the rack 7.

[0028] A workbench 14 capable of conveying rubber strips is fixedly connected to one side of the box body 1, and transmission tubes 15 are fixedly connected to both sides of the workbench 14. One end of a piston rod 16 is slidably connected to the inside of one end of the transmission tube 15, and a piston rod 2 16 is slidably connected to the inside of the other end of the transmission tube 15. One end of the piston rod 2 16 is fixedly connected to a bearing with a seat, so that when the piston rod 16 moves downward to squeeze the medium water or air in the transmission tube 15, the piston rod 2 16 can drive the transmission cylinder 17 away from the rotating cylinder 18, so that the rotation of the transmission cylinder 18 no longer drives the rubber strip to feed, and the inner side of the bearing with a seat is rotatably connected to the transmission cylinder 17, and one side of the workbench 14 and the top of the transmission cylinder 17 are rotatably connected to the transmission cylinder 18, and one side of the rotating cylinder 18 is connected to a driving motor 19, and both ends of the rotating cylinder 18 are rotatably connected to two connecting seats, and the bottom of the driving motor 19 is connected to the connecting seat through a mounting seat, and a through groove is opened on the surface of the connecting seat, and both ends of the intermediate shaft of the transmission cylinder 17 are slidably arranged in the through groove.

[0029] When the rotating cylinder 18 rotates, since the transmission cylinder 17 is close to the rotating cylinder 18, the friction of the rotating cylinder 18 can make the transmission cylinder 17 rotate through the rubber strip, thereby achieving the effect of rubber strip feeding.

[0030] The implementation principle of a rubber strip cutting device for tire production in the embodiment of the present application is as follows: when cutting is required, the rubber strip is passed through the transmission cylinder 17 and the rotating cylinder 18 and placed on the workbench, the driving motor 19 is started, the hydraulic rod 2 is started, the hydraulic rod 2 drives the connecting plate 3 to move, the connecting plate 3 drives the cutting knife 4 and the extension rod 5 to move downward, after the cutting is completed, the hydraulic rod 2 moves upward, the extension rod 5 drives the rack 4 to move upward, the rack 4 drives the matching wheel 13 to rotate, the matching wheel 13 drives the ratchet 12 to rotate, the ratchet 12 drives the transmission gear 11 to rotate, and the transmission gear 11 makes the U-shaped rod 10 rotates, the U-shaped rod 10 drives the transmission rod 9 to move, and the transmission rod 9 makes the discharge plate 8 complete a reciprocating motion, automatically collecting the rubber strip into the box body 1, and while the hydraulic rod 2 rises, the extension rod drives the piston rod 1 6 upward, and drives the piston rod 2 16 upward through the transmission tube 15, and the piston rod 2 16 drives the transmission cylinder 17 to rise at the same time, so that the rubber strip moves forward. When the rubber strip moves to a suitable position, the hydraulic rod 2 descends and the transmission cylinder 17 separates, so that the rubber strip stops moving at a fixed length, which is convenient for controlling the length of the rubber strip cut, making it more convenient to cut the rubber strip at a fixed length.

[0031] When the length of the rubber strip to be cut needs to be adjusted, the time from the stop to the start of the hydraulic rod 2 is controlled, and the length of the rubber strip to be cut is controlled by controlling the time difference.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
