[0002] In recent years, with the rapid development of my country's automobile industry, the tire industry has also entered a period of rapid growth. my country has become a major tire producer and consumer in the world. Generally, discarded tires are pyrolyzed to achieve recycling and reuse of discarded tires.

[0003] When the waste tires are centrally processed for cracking, the stacked waste tires are picked up one by one and in an orderly manner by a gripper and placed on a feeding conveyor. Under the conveyor, the waste tires are fed into the cracking furnace for cracking. However, the existing grippers generally use manipulators, but the cost of manipulators is relatively high; in addition, there are also grippers with fixed opening angles, but the gripping process of such grippers is inconvenient and unstable.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0016] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0017] Combination Figure 1-3As shown, the tire gripper includes a top seat 1, a pair of slides 2 are slidably provided at the bottom of the top seat 1, each slide 2 is provided with a pair of clamping rods 3 downwardly, a connecting frame 4 is provided downwardly on the top seat 1 and the connecting frame 4 is located below the slide 2, a spur rack 5 is provided on the top seat 1 for sliding toward the two slides 2 respectively, the outer ends of the spur racks 5 rotate with the slides 2 on the same side, a driving gear 6 is rotatably provided on the top seat 1 and the driving gear 6 is respectively meshed and installed with the two spur racks 5, a driving mechanism for rotating the driving gear 6 is also provided on the top seat 1, and an identification mechanism is provided on the bottom surface of the connecting frame 4 downwardly.

[0018] In recent years, with the rapid development of my country's automobile industry, the tire industry has also entered a period of rapid growth. my country has become a major tire producer and consumer in the world. Generally, discarded tires are pyrolyzed to achieve recycling and reuse of discarded tires.

[0019] When the waste tires are cracked, the stacked waste tires are firstly picked up one by one and in order by the device and placed on the feeding conveyor. Under the transportation of the feeding conveyor, the waste tires are fed into the cracking furnace for cracking.

[0020] In specific work, the top seat in the gripper is generally installed on a mechanical arm, and can also be installed on the moving end of the transplanting mechanism, through which the movement of the device is driven.

[0021] When clamping the waste tires, the gripper first moves toward the pile of waste tires, and the two pairs of clamping rods are respectively located at the two ends of the top seat. During the movement of the gripper, the position of the waste tire is identified and located by the identification mechanism. After the specific position of the waste tire is determined, the gripper moves toward the waste tire, and after moving into position, the waste tire is located between the two pairs of clamping rods. Then the driving mechanism drives the driving gear to rotate, and when the driving gear rotates in the opposite direction, the two spur racks move toward each other, and the two spur racks pull the slide on the same side to move inward, and then both pairs of clamping rods move toward the waste tire and clamp it. Finally, the gripper moves the waste tire to the feeding conveyor platform, and it is sent to the cracking furnace for cracking treatment.

[0022] As a preferred structure, a stopper 7 is fixed above each clamping rod 3, which can limit the tire. An anti-skid threaded sleeve 8 is provided on the clamping rod 3 and below the stopper 7. Under the friction of the anti-skid threaded sleeve, the clamping rod can clamp the tire more stably to prevent the tire from falling off.

[0023] In this device, if Figure 2The driving mechanism includes a pair of driving cylinders 17 mounted on the top seat 1, and the driving shaft of the driving cylinder 17 is rotatably connected to the slide 2. When the driving shafts of the two driving cylinders are retracted at the same time, the two pairs of clamping rods move toward each other to clamp the tire. Specifically, when the driving shafts of the two driving cylinders are retracted at the same time, the two slides slide toward each other, thereby pushing the two spur racks to slide toward each other, and the driving gear will rotate. In this way, the entire tire clamping process is more stable and reliable.

[0024] In this structure, if Figure 3 The identification mechanism includes a hollow box body 16, an industrial camera 9 is arranged in the box body 16, and fill lights 10 are arranged downwards on all four sides of the connecting frame 4.

[0025] When identifying and locating waste tires, the industrial camera is mainly used to determine the specific location of the waste tires through visual recognition, thereby achieving the purpose of locating the waste tires. This allows the gripper to accurately clamp the waste tires. During the identification process, four fill lights provide sufficient light sources for the industrial camera to improve the accuracy of identification.

[0026] Further as a preferred structure, Figure 1 A pair of fixing blocks 11 are provided around the connecting frame 4, and the fill light 10 is fixed on the same pair of fixing blocks 11. A pair of threaded holes are opened on the fixing blocks 11 (blocked in the figure). A pair of ear seats 12 are provided on the lamp holder of the fill light. An arc groove 13 and a locking hole (blocked in the figure) are opened at the upper and lower positions of each ear seat 12. Nuts 15 are respectively inserted into the arc groove 13 and the locking hole, and the nuts 15 are screwed into the threaded holes and locked.

[0027] In this structure, the fill lights are arranged downwards on all four sides of the connecting frame. With the help of the four fill lights, sufficient light source can be provided for the industrial camera. The fill lights are all detachable installation structures, which is convenient for later replacement. At the same time, the installation angle of the fill lights can also be adjusted according to the actual situation on site.

[0028] When the fill light needs to be replaced, first remove the fill light to be replaced, and then install the new fill light on the same pair of fixed blocks. Specifically: first align the two ear seats on the lamp holder with the fixed blocks on the same side according to the requirements, that is, the arc groove and locking hole on the ear seat are aligned with the two threaded holes on the fixed block on the same side, and then insert a nut into the arc groove and locking hole, and a gasket 14 is provided on the nut 15. The nut is screwed into the corresponding threaded hole, and the preliminary installation of the fill light is completed at this time.

[0029] When you need to adjust the installation angle of the fill light, just turn the lamp holder of the fill light. Finally, tighten all the nuts. In the process of turning the fill light, the nuts in the arc groove play a guiding role.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
