[0065] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0066] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0067] As shown in Figure 1-36, this invention is an automatic tire trimming machine, including a trimming machine body 2. A tire inlet device 1 is provided on the tire inlet side of the trimming machine body 2, and a tire outlet device 3 is provided on the tire outlet side. The tire inlet device 1 includes a tire inlet frame 1.1 and a tire clamping and centering mechanism 1.4 mounted on the tire inlet frame 1.1. Tires conveyed horizontally by the conveyor line enter the tire inlet device 1 and are adjusted to a vertical position. The tire clamping and centering mechanism 1.4 adjusts the tire so that its center in the tire width direction coincides with the center of the tire inlet side of the trimming machine body 2. A 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 trimming machine body 2. In actual production, the tire inlet device 1 can be arbitrarily set on the left or right side of the trimming machine body 2; that is, the tire inlet device 1 has a left-right interchangeable structure, which can adapt to the diverse functional requirements of the factory and achieve adjustment of the tire inlet direction.

[0068] As shown in Figure 3, a lower tire roller conveyor 1.2 is installed on the tire inlet frame 1.1. The lower tire roller conveyor 1.2 is used to adjust the horizontal tire to a vertical position.

[0069] 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 barcode reader assembly 1.5.4 is also installed on the tire inlet frame 1.1 to read the tire barcode.

[0070] As shown in Figures 3 and 4, the first embodiment of the tire lowering roller conveyor 1.2 includes a vertical tire-stopping roller and an arc-shaped roller slide. During operation, after the tire is horizontally conveyed from the external conveyor line, it slides downwards along the arc-shaped roller slide until it reaches a vertical position. It is understood that, to ensure reliable tire entry, the upper end of the arc-shaped roller slide is lower than the top surface of the tire entry frame 1.1.

[0071] As shown in Figure 5, the second embodiment of the tire lowering roller conveyor 1.2 includes a vertical tire-stopping roller and a set of non-powered rollers capable of flipping. Multiple rollers are rotatably mounted at both ends of the support of the non-powered rollers. In this structure, the horizontally conveyed tire is guided and limited by the rollers on both sides of the non-powered rollers, and is flipped by the drive cylinder of the non-powered rollers, thus turning the horizontal tire to a vertical position. Under this condition, the conveyor line can operate smoothly even with a tire entry height lower than required, avoiding unnecessary on-site modifications. The vertically arranged tire-stopping rollers are the same as in the previous structure.

[0072] As shown in Figure 10-12, the tire rotation drive assembly 1.5.3 includes a first mounting base 1.5.1 and a second mounting base 1.5.2. A belt bracket 1.5.3.2 is mounted on both the first and second mounting bases 1.5.1 and 1.5.2, respectively. A driven shaft and a drive shaft are mounted at both ends of the belt bracket 1.5.3.2 along its length. A flat belt 1.5.3.3 is tensioned on the driven shaft and the drive shaft. The drive shaft is driven by a drive 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 during operation.

[0073] In practical applications, to adapt to processes without code reading requirements, as shown in Figure 11, the tire rotation drive assembly 1.5.3 can also be optionally equipped with a fixed tire support plate 1.5.3-2, which is the second structure of the tire rotation drive assembly 1.5.3. As shown in Figure 12, the second mounting base 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 handle production processes that require tire discharge at the tire inlet device. When working, the lifting assembly 1.5.2-2 raises the tire rotation drive assembly 1.5.3, and the tire rolls out of the tire inlet device towards the motor side under the action of gravity.

[0074] As shown in Figure 6-8, the tire clamping and centering mechanism 1.4 includes a tire clamping plate 1.1.1, a tire clamping plate mounting seat 1.4.2, a linear bearing assembly 1.4.3, a fixed seat 1.4.4, a clamping cylinder 1.4.5, and a Z-shaped connecting rod 1.4.6.

[0075] Two sets of linear bearing assemblies 1.4.3 are respectively mounted on corresponding fixed seats 1.4.4 at both ends. Two sets of tire clamping 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 clamping plate mounting seats 1.4.2 are centrally symmetrically linked by a Z-shaped connecting rod. A clamping cylinder 1.4.5 is installed between the two fixed seats 1.4.4 on one side. The piston rod of the clamping cylinder 1.4.5 is connected to the corresponding tire clamping plate mounting seat 1.4.2. A tire clamping plate 1.4.1 is installed on the tire clamping plate mounting seat 1.4.2.

[0076] As shown in Figure 7, the two 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 mounted on the connecting rod. Each end rod is hinged to one end rod at both ends of the middle rod. The other end of the end rod is hinged to the corresponding clamp plate mounting seat 1.4.2.

[0077] As shown in Figures 8 and 9, in specific applications, the linear bearing assembly is designed with high-precision and low-precision options. Linear bearing assembly 1.4.3 is a high-precision configuration, while roller slide bar 1.4.3.1 is a medium-to-low precision configuration, which can meet the needs of different customers. The roller slide bar 1.4.3.1 mainly replaces the 4 sets of linear bearings in linear bearing assembly 1.4.3 with 16 sets of concave rollers, which reduces costs and assembly difficulty, while also reducing production costs and shortening the lead time.

[0078] As shown in Figures 13 and 14, 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. An upper blade assembly lifting mechanism 2.2 is provided at the upper part of the power chamber, and an upper blade assembly mechanism 2.3 is connected to the upper blade assembly lifting mechanism 2.2. A lower blade assembly lifting mechanism 2.7 is provided at the lower part of the power chamber, and a lower blade assembly mechanism 2.8 is connected to the lower blade assembly lifting mechanism 2.7. Both the upper blade assembly mechanism 2.3 and the lower blade assembly mechanism 2.8 are located in the working chamber. A tire kicking mechanism 2.10 is provided at the drive roller mechanism 2.4, and the tire kicking mechanism 2.10 is arranged along the tire exit direction.

[0079] During operation, the tire to be processed enters from the left or right side of the frame 2.1 through the tire infeeding device 1, rolls to the middle position of the frame 2.1, and is finally placed on the drive roller mechanism 2.4. The upper pressure roller mechanism 2.5 limits the upper part of the tire. Then, the upper cutter group mechanism 2.3 moves downward under the action of the upper cutter group lifting mechanism 2.2 until the upper cutter group mechanism 2.3 corresponds to the tire tread. At the same time, the lower cutter group lifting mechanism 2.7 moves upward to the position where the lower cutter group mechanism 2.8 cleans the tire sidewall. The drive roller mechanism 2.4 makes the tire rotate at high speed. The excess rubber strips and rubber edges are removed by the corresponding parts of the upper cutter group mechanism 2.3 and the lower cutter group mechanism 2.8 using relative motion. After the cutting work is completed, the drive roller decelerates, and at the same time, the tire kicking mechanism 2.10 is activated to lift one radial side of the bottom of the tire. Using the kinetic energy of the tire rotation, it rolls from the other side of the tire infeeding direction to the tire exiting device.

[0080] A drive roller mechanism 2.4 for supporting the tire is provided in the middle of the working chamber, an upper pressure roller mechanism 2.5 that cooperates with the drive roller mechanism 2.4 is provided in the upper part of the working chamber, and a waste rubber strip collection assembly 2.6 is provided at the bottom of the working chamber to collect tire lint. As shown in Figure 32, the tire kicking mechanism 2.10 includes a tire kicking cylinder 2.10.1, a tire kicking rod 2.10.2, and a rotating shaft assembly 2.10.3. The rotating shaft assembly 2.10.3 is installed in the middle of the frame 2.1. The tire kicking rod 2.10.2 is connected to the rotating shaft assembly 2.10.3. The mounting part of the tire kicking cylinder 2.10.1 is fixed to the tire-out direction side of the middle of the frame 2.1. The piston rod of the tire kicking cylinder 2.10.1 is connected to one end of the tire kicking rod 2.10.2. When the tire kicking cylinder 2.10.1 moves, it drives the other side of the tire kicking rod 2.10.2 to move upward, pushing the tire so that the tire can be smoothly discharged from the trimmer body 2 using its rotational inertia. A guide mechanism 2.11 is provided on the frame 2.1 to guide the tire discharge. It can be understood that the tire kicking rod 2.10.2 is used to push the tire, and a tire kicking plate is fixed at one end to achieve a reliable tire kicking action.

[0081] As shown in Figures 15-17, the upper blade assembly lifting mechanism 2.2 includes an upper blade assembly lifting base 2.2.1 and an upper blade assembly lifting screw 2.2.2 mounted on the upper blade assembly lifting base 2.2.1. An upper blade assembly lifting screw nut 2.2.7 is threaded onto the upper blade assembly lifting screw 2.2.2, and the upper blade assembly lifting screw nut 2.2.7 is fixedly connected to the upper blade assembly lifting screw nut fixing seat 2.2.8.

[0082] A first slide rail 2.2.3 is installed on the upper blade assembly lifting base 2.2.1. An upper blade assembly fixing plate 2.2.5 is slidably guided onto the first slide rail 2.2.3. The upper blade assembly fixing plate 2.2.5 is securely connected to the upper blade assembly lifting screw nut fixing seat 2.2.8. A first centralized lubrication assembly 2.2.6 is also fixedly connected to the upper blade assembly lifting screw nut fixing seat 2.2.8. The first centralized lubrication assembly 2.2.6 provides centralized lubrication to corresponding lubrication points via a hose. First telescopic bellows covers 2.2.9 are fixedly connected to both ends of the upper blade assembly lifting base 2.2.1 and to the upper blade assembly fixing plate 2.2.5 to protect the first slide rail 2.2.3 and the upper blade assembly lifting screw 2.2.2, extend their service life, and reduce machine maintenance costs. A first lifting motor 2.2.4 is installed on the side of the upper blade assembly lifting base 2.2.1, which drives the upper blade assembly lifting screw 2.2.2 to rotate.

[0083] As shown in Figures 20-22, the upper tool assembly mechanism 2.3 includes an upper tool assembly base 2.3.12. A servo motor 2.3.19 is installed on one side of the upper tool assembly base 2.3.12. The servo motor 2.3.19 is connected to a transverse lead screw 2.3.15 located in the upper tool assembly base 2.3.12 via a coupling. Linear slide rods 2.3.14 are respectively installed on both sides of the transverse lead screw 2.3.15. A lead screw nut seat is threaded onto the transverse lead screw 2.3.15, which can... The understanding is that a screw nut seat is threaded to each of the left and right sides of the transverse lead screw 2.3.15. The screw nut seat is slidably connected to the linear slide bar 2.3.14. An upper tool holder slide plate 2.3.16 is mounted on the screw nut seat, and a tool assembly device 2.3.18 is mounted on the upper tool holder slide plate 2.3.16. The tool assembly devices 2.3.18 on the left and right sides are symmetrically arranged and have a certain tilt angle. The nuts in the screw nut seats on the left and right sides can be in the same direction or in opposite directions. When the nuts are in the same direction, the upper tool holder slide plates 2.3.16 on the left and right sides move in the same direction under the action of the transverse lead screw 2.3.15; when the nuts are in opposite directions, the upper tool holder slide plates 2.3.16 on the left and right sides move towards each other under the action of the transverse lead screw 2.3.15.
