[0051] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0052] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. The described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0053] like Figure 1-36As shown, the present invention is an automatic tire trimmer, including a trimmer body 2, a tire inlet device 1 is arranged on the tire inlet side of the trimmer body 2, and a tire outlet device 3 is arranged on the tire outlet side of the trimmer body 2, the tire inlet device 1 includes a tire inlet frame 1.1 and a tire clamping and centering mechanism 1.4 installed on the tire inlet frame 1.1, the tire transported horizontally by the conveyor line enters the tire inlet device 1 and is adjusted to a vertical state, and the tire clamping and centering mechanism 1.4 adjusts the tire to the center of the tire width direction coincident with the center of the tire inlet side of the trimmer body 2, and the tire rotation drive assembly 1.5.3 is also installed on the tire inlet frame 1.1 to drive the tire to rotate and transport the tire to the trimmer body 2. In specific production, the tire inlet device 1 can be arbitrarily arranged on the left or right side of the trimmer body 2, that is, the tire inlet device 1 is a left-right interchangeable structure, which can adapt to the functions required by the factory for diversification and achieve the adjustment of the tire inlet direction.

[0054] like Figure 3 As shown, a tire lower roller 1.2 is installed on the tire inlet frame 1.1, and the tire lower roller 1.2 is used to adjust the tire in a horizontal state to a vertical state.

[0055] A pneumatic cabinet 1.3 is installed at the lower part of the tire inlet frame 1.1. The pneumatic cabinet 1.3 is a highly integrated design product. A code reader assembly 1.5.4 is also installed on the tire inlet frame 1.1 to read the barcode of the tire.

[0056] like Figure 3 , 4 As shown, the first embodiment of the tire lowering roller 1.2: the tire lowering roller 1.2 includes a vertical tire blocking roller and an arc-shaped roller slide. When working, after the tire is horizontally conveyed from the external conveyor line, it slides downward along the arc-shaped roller slide until it becomes a vertical state. It can be understood that in order to ensure reliable tire feeding, the upper end of the arc-shaped roller slide is lower than the top surface of the tire feeding frame 1.1.

[0057] like Figure 5 As shown, the second implementation of the lower tire roller 1.2: the lower tire roller 1.2 includes a vertical tire blocking roller and a group of unpowered rollers that can be turned over. The two ends of the bracket of the unpowered roller are rotatably provided with multiple rollers. Under this structure, the horizontally transported tire is guided and limited by the rollers on both sides of the unpowered roller, and is driven by the driving cylinder of the unpowered roller to turn over, thereby turning the horizontal tire to a vertical state. Under this working condition, the conveyor line that is lower than the required tire feeding height can also be smoothly produced, avoiding unnecessary modifications on site, and the vertically arranged tire blocking roller is the same as in the previous structure.

[0058] like Figure 10-12As shown, the tire rotation drive assembly 1.5.3 includes a first mounting seat 1.5.1 and a second mounting seat 1.5.2, on which a belt bracket 1.5.3.2 is mounted, and a driven shaft and a driving shaft are mounted at both ends of the belt bracket 1.5.3.2 in the length direction, respectively, and a flat belt 1.5.3.3 is tensioned on the driven shaft and the driving shaft, and the driving shaft is driven by a driving motor 1.5.3.1 mounted on the belt bracket 1.5.3.2. A barcode reader assembly 1.5.4 is mounted on the side of the flat belt 1.5.3.3, and reads the barcode on the tire when working.

[0059] In actual practice, in order to adapt to processes without code reading requirements, such as Fig.11 As shown, the tire rotation drive assembly 1.5.3 can also be equipped with a fixed tire bearing plate 1.5.3-2, which is the second structure of the tire rotation drive assembly 1.5.3. Fig.12 As shown, the second mounting seat 1.5.2 in the tire rotation drive assembly 1.5.3 can also be optionally equipped with a lifting assembly 1.5.2-2, which can cope with the production process that requires tire removal at the tire inlet device. The lifting assembly 1.5.2-2 lifts the tire rotation drive assembly 1.5.3 when working, and the tire rolls out of the tire inlet device to the motor side under the action of gravity.

[0060] like Figure 6-8 As shown, the tire clamp centering mechanism 1.4 includes a tire clamp plate 1.1.1, a tire clamp plate mounting seat 1.4.2, a linear bearing assembly 1.4.3, a fixing seat 1.4.4, a clamping cylinder 1.4.5 and a Z-shaped connecting rod 1.4.6.

[0061] The two ends of the two sets of linear bearing assemblies 1.4.3 are respectively installed on the corresponding fixed seats 1.4.4, and two sets of tire plate mounting seats 1.4.2 are slidably arranged on the two sets of linear bearing assemblies 1.4.3. The two sets of tire plate mounting seats 1.4.2 are centrally symmetrically linked through a Z-shaped connecting rod. A clamping cylinder 1.4.5 is installed between the two fixed seats 1.4.4 on one side, and the piston rod of the clamping cylinder 1.4.5 is connected to the corresponding tire plate mounting seat 1.4.2, and the tire plate 1.4.1 is installed on the tire plate mounting seat 1.4.2.

[0062] like Figure 7 As shown, the two sets of linear bearing assemblies 1.4.3 are connected by a connecting rod, the middle rod of the Z-shaped connecting rod 1.4.6 is rotatably set on the connecting rod, the two ends of the middle rod are respectively hinged to an end rod, and the other end of the end rod is hingedly connected to the corresponding tire clamping plate mounting seat 1.4.2.

[0063] like Figure 8 , 9As shown, in specific applications, the linear bearing assembly is designed with high-precision and low-precision options. The linear bearing assembly 1.4.3 is a high-precision configuration, and the roller slide bar 1.4.3.1 is a medium-to-low-precision configuration, which can meet the needs of different customers. The pulley slide bar 1.4.3.1 mainly replaces the 4 sets of linear bearings in the linear bearing assembly 1.4.3 with 16 sets of concave rollers, which reduces the cost and assembly difficulty, while reducing production costs and shortening construction time.

[0064] like Fig.13 , 14 As shown, the trimmer body 2 includes a frame 2.1, which is divided into a power chamber and a working chamber by a partition to effectively ensure the service life of the components.

[0065] During operation, the tire to be processed enters from the left or right side of the frame 2.1 through the tire inlet device 1, rolls to the middle position of the frame 2.1, and is finally placed on the driving roller mechanism 2.4. The upper pressure roller mechanism 2.5 limits the upper part of the tire, and then the upper knife group mechanism 2.3 moves downward under the action of the upper knife group lifting mechanism 2.2 until the upper knife group mechanism 2.3 corresponds to the tire tread. At the same time, the lower knife group lifting mechanism 2.7 moves upward to the position where the lower knife group mechanism 2.8 cleans the sidewall. The driving roller mechanism 2.4 rotates the tire at high speed, and the corresponding parts of the upper knife group mechanism 2.3 and the lower knife group mechanism 2.8 remove excess rubber strips and rubber edges by relative motion. After the cutting work is completed, the driving roller slows down, and the kicking mechanism 2.10 is activated at the same time to lift one radial side of the bottom of the tire, and use the kinetic energy of the tire rotation to roll it from the other side of the tire inlet direction to the tire outlet device.

[0066] A driving roller mechanism 2.4 for supporting the tire is arranged in the middle of the working chamber, an upper pressing roller mechanism 2.5 cooperating with the driving roller mechanism 2.4 is arranged in the upper part of the working chamber, and a waste rubber strip collecting assembly 2.6 is arranged at the bottom of the working chamber to collect tire scraps.
