The lifting assembly 5 is provided with a bracket 501, the two sides of the bracket 501 are provided with sliding blocks, and each of the two sliding blocks is provided with a lifting sliding rail 502. The top ends of the two lifting sliding rails 502 are provided with a lifting fixed seat 503 arranged horizontally. The top of the bracket 501 is provided with a lifting lead screw 504 and a servo motor 505 for driving the lifting lead screw 504. The top of the lifting lead screw 504 is connected with the lifting fixed seat 503, and the height of the lifting fixed seat 503 can be adjusted through the lifting lead screw 504.

[0033] As a preferred embodiment, the displacement assembly 2 comprises at least two sliding blocks mounted on the lifting fixed seat 503, and displacement sliding rails 201 in sliding cooperation with the sliding blocks. The displacement sliding rails 201 are provided with telescopic beams 202, and are further provided with telescopic cylinders 203 for driving the telescopic beams 202 to move linearly relative to the sliding blocks. Under the driving of the telescopic cylinders 203, the telescopic beams 202 can stably slide along the displacement sliding rails 201, and then realize the linear movement of the vacuum chuck assembly 1. This design enables the vacuum chuck assembly 1 to accurately and quickly adhere to the tail belt 7, and prepares for the subsequent adsorption and cutting operation.

[0034] As a preferred embodiment, the lifting fixed seat 503 is further provided with a positioning cylinder 6, and at least one positioning tip 601 is mounted on the output end of the positioning cylinder 6. The positioning tip 601 is below the telescopic beam 202. When the telescopic beam 202 moves to a specified position, the positioning tip 601 can be driven by the positioning cylinder 6 to insert into the telescopic beam 202 to position it, so as to ensure the accuracy of the position.

[0035] As a preferred embodiment, the swing mechanism 4 comprises a swing arm 401 and a swing cylinder 402. The swing arm 401 is connected to the telescopic beam 202, and the vacuum chuck assembly 1 is mounted on one end of the swing arm 401. The swing cylinder 402 is in transmission connection with the other end of the swing arm 401. After the tail belt 7 is cut, the swing cylinder 402 is started to drive the swing arm 401 to rotate around the shaft joint point, so that the vacuum chuck assembly 1 swings to a specified position, and the cut tail belt 7 is loosened and falls into a recycling box or other specified recycling position. During the swinging process, the vacuum chuck assembly 1 still maintains the adsorption force on the tail belt 7 to prevent the tail belt 7 from falling off, and ensures the smooth progress of the recycling work.

[0036] As a preferred embodiment, the vacuum chuck assembly 1 of the utility model comprises at least two telescopic shaft shaft seats 101 fixed at the end of the swing arm 401 and telescopic shafts 102 installed in the telescopic shaft shaft seats 101, the telescopic shaft 102 is provided with a spring 103, the end of the telescopic shaft 102 is provided with a telescopic shaft mounting seat 104, the telescopic shaft mounting seat 104 is fixed with front and rear supports 106, the front and rear supports 106 extend forward and backward to the telescopic shaft mounting seat 104, the telescopic shaft mounting seat 104 is pivotally connected with a fixed plate 107, the fixed plate 107 is installed with at least two telescopic shaft shaft seats 108, the telescopic shaft shaft seats 108 are installed with telescopic shafts 105, the tail end of the telescopic shaft 105 is provided with a joint 105a clamped in the inclined groove 106a arranged at the rear end of the front and rear supports 106, the front end of the telescopic shaft 105 is installed with a vacuum chuck body 109, the telescopic shaft mounting seat 104 is further provided with a pull-down gas cylinder 1010 for driving the telescopic shaft 105 to rotate around the pivot joint, so that the front end of the telescopic shaft 105 is retracted backward and moves downward. It should be noted that the main function of the telescopic shaft 102 is to enable the vacuum chuck body 109 to abut against the tail belt 7, and the spring 103 is used to enable the vacuum chuck body 109 to stably adsorb the tail belt 7. After adsorption, the pull-down gas cylinder 1010 is actuated, the front end of the telescopic shaft 105 is retracted backward and moves downward, the tail belt 7 is separated from the product, and the subsequent cutting operation is facilitated, the cutting assembly 3 can more accurately complete the cutting work, and the product is prevented from being damaged during the cutting process.

[0037] As a preferred embodiment, the cutting assembly 3 of the utility model comprises a blade 301 installed below the front end of the front and rear supports 106 and a blade driving gas cylinder 302 for driving the blade 301 to move linearly to cut the tail belt 7. When the blade driving gas cylinder 302 is started, it will push the blade 301 to move linearly to cut the tail belt 7 at a speed, so that the cut is neat and smooth, and the tail belt 7 is prevented from being left or incompletely cut.

[0038] The working process of the utility model comprises the following steps:

[0039] Firstly, the control system sends an instruction to the servo motor 505 of the lifting assembly 5 according to the specification of the tire and the approximate height information of the tail belt 7. The servo motor 505 is started, and drives the lifting lead screw 504 to rotate. Since the top of the lifting lead screw 504 is connected with the lifting fixed seat 503, along with the rotation of the lifting lead screw 504, the lifting fixed seat 503 will move vertically along the lifting slide rails 502 on the two sides of the bracket 501. By accurately controlling the rotation direction and the number of turns of the servo motor 505, the height of the lifting fixed seat 503 can be accurately adjusted, so that the vacuum chuck assembly 1 installed on the subsequent structure reaches the appropriate height position, and prepares for the subsequent tail belt 7.

[0040] When the vacuum chuck assembly 1 reaches the appropriate height, the control system sends an action command to the telescopic cylinder 203 of the displacement assembly 2. The telescopic cylinder 203 starts, pushing the telescopic beam 202 installed on the displacement slide rail 201 to move linearly along the slide block. The movement of the telescopic beam 202 drives the vacuum chuck assembly 1 associated therewith to move. Under the stable driving of the telescopic cylinder 203, the telescopic beam 202 can accurately and quickly push the vacuum chuck assembly 1 against the tail belt 7, so that the vacuum chuck assembly 1 can fully contact the tail belt 7, to ensure that the vacuum chuck assembly 1 can suck the tail belt 7. At this time, the telescopic shaft 102 uses the elastic action of the spring 103 thereon to enable the vacuum chuck body 109 to be self-adaptively abutted against the tail belt 7, to ensure that the vacuum chuck body 109 fully contacts the tail belt 7.

[0041] When the vacuum chuck assembly 1 stably sucks the tail belt 7, the control system sends a command to the pull-back and down cylinder 1010 on the running shaft mounting seat 104. The pull-back and down cylinder 1010 starts, driving the running shaft 105 to rotate around the pivot joint. Since the tail end of the running shaft 105 is provided with a joint 105a clamped in the inclined groove 106a arranged at the rear end of the front and rear supports 106, during the rotation, the front end of the running shaft 105 will be retracted backward and move downward, so that the tail belt 7 is pulled away from the tire product by a certain distance. This operation creates favorable space conditions for the subsequent cutting operation, avoiding damage to the tire product during the cutting process.

[0042] After the tail belt 7 is pulled away to the appropriate distance, the control system sends a command to the blade driving cylinder 302 of the cutting assembly 3. The blade driving cylinder 302 starts, pushing the blade 301 installed below the front end of the front and rear supports 106 to move linearly, so as to smoothly complete the cutting of the tail belt 7.

[0043] After the tail belt 7 is cut, the control system sends a command to the swing cylinder 402 of the swing mechanism 4. The swing cylinder 402 starts, driving the swing arm 401 pivotally connected with the telescopic beam 202 to rotate around the pivot joint. Since the vacuum chuck assembly 1 is installed at one end of the swing arm 401, the rotation of the swing arm 401 will drive the vacuum chuck assembly 1 to swing. During the swinging, the vacuum chuck assembly 1 still maintains the suction force on the cut tail belt 7, to prevent the tail belt 7 from falling. When the swing arm 401 rotates to the designated recovery position, the control system stops the work of the vacuum pump, and the vacuum chuck assembly 1 loses the suction force, so that the cut tail belt 7 falls into the recovery box or other designated recovery position, to complete the recovery of the tail belt 7.

[0044] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
