[0002] The tread is the only part of the tire that comes into contact with the ground, and it largely determines the safety performance of the car. During the tire production process, bubbles may appear at the bottom of the tread, resulting in the tread and reinforcement layer being delaminated, posing a major safety hazard.
[0003] At present, a Chinese patent discloses a tire embryo surface puncturing device, and its application number is 202322321697X. In the technical solution of this application, the tire embryo is fixed by a tire pressure roller, a puncturing roller and a centering roller, so as to process the tire embryo.
[0004] In combination with the above-mentioned disclosed technical solution, when processing the tire blank, since the tire blank needs to be restricted by the centering roller during the fixed rotation process, the tire blank needs to bypass the centering roller when loading and unloading the tire blank. Therefore, when the processed tire blank is manually removed, it not only increases the use of manpower but also reduces work efficiency. Therefore, we propose a tire embryo surface puncturing device to solve this problem. Utility Model Content

[0029] Two mounting bars 16 are fixedly connected to the inner side of the workbench 1, and a toothed plate assembly 13 is slidably connected to the bottom of the mounting bars. The toothed plate assembly 13 includes a rack, two tooth blocks and four telescopic rods. Both sides of the rack and the tooth blocks are fixedly connected by telescopic rods. The telescopic rods are composed of sleeves and support rods and can be stretched and retracted. Springs are sleeved on the outer sides of the telescopic rods. The bottom of the toothed plate assembly 13 is meshedly connected with a gear 7. A connecting shaft 10 is fixedly connected between the two gears 7. One end of the connecting shaft passes through the workbench 1 and is connected to a second motor 2 that drives the connecting shaft 10 to rotate. A slide groove is provided on the surface of the mounting strip 16, and a U-shaped rod 11 is slidably connected to the inner side of the slide groove. The two ends of the U-shaped rod 11 are respectively connected to two tooth plate assemblies 13 that drive the U-shaped rod 11 to move. A moving block 8 is sleeved on the middle part of the outer side of the U-shaped rod 11, and an oblique groove 15 is provided in the middle part of the moving block 8 to enable the moving block 8 to move up and down and forward and backward. The front end of the oblique groove 15 is sloped, and the rear end of the oblique groove 15 is straight. A fixed shaft 12 is penetrated through the inner side of the oblique groove 15, and the two ends of the fixed shaft 12 are respectively fixedly connected to the surfaces of the two mounting strips 16.
[0030] Two rollers 5 for fixing the tire blank, one end of the intermediate shaft of the roller 5 is rotatably connected to the surface of the moving block 8, the front end of the roller 5 is abutted against a support frame 6 for supporting the roller 5, and both ends of the support frame 6 are fixedly connected to the inner wall of the workbench 1, and the two rollers 5 are respectively located below the licker-in roller 9 and the pressure wheel 14.
[0031] The implementation principle of a fetal embryo surface puncturing device in the embodiment of the present application is as follows: start the second motor 2 to drive the connecting shaft 10 to rotate, and the connecting shaft 10 rotates to drive the gear 7 to rotate, and the gear 7 rotates to drive the toothed plate assembly 13 to move, and the toothed plate assembly 13 moves to drive the U-shaped rod 11 to slide in the slide groove on the surface of the mounting plate 16, and the sliding of the U-shaped rod 11 drives the movement of the moving block 8, and the movement of the moving block 8 causes the fixed shaft 12 to slide in the oblique groove 15, and when the fixed shaft 12 slides in the straight strip part in the oblique groove 15, the front end of the roller 5 is separated from the support of the support frame 6, and when the fixed shaft 12 slides to a slope in the oblique groove 15, the moving block 8 and the roller 5 are inclined, and because the rack on the toothed plate assembly 13 is connected to the tooth block by a telescopic rod, the gear 7 reaches the tooth block. When the gear 7 reaches the tooth block, the fixed shaft 12 reaches one end of the oblique groove 15, so that the fixed shaft 12 stops moving when it reaches both ends of the oblique groove 15. At this time, the tire embryo is placed on the roller 5, and the second motor 2 is reversed to make the front end of the roller 5 contact the support frame 6 again, so that the tire embryo is squeezed and fixed by the roller 5, the licker-in roller 9 and the pressure wheel 14, and due to the action of the support frame 6, the tire embryo will not fall out during processing. At this time, the first motor 3 is turned on to rotate the licker-in roller 9, and the rotation of the licker-in roller 9 drives the tire embryo to rotate, and the pores on the surface of the tire embryo are punctured. When the tire embryo is punctured, the first motor 3 is turned off, and the second motor 2 is reversed to make the moving block 8 move backward and then tilted, so that the tire embryo on the roller 5 falls into the collecting tank 4.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
