[0033] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0034] Figure 1 The manual laminating machine 100 using the present invention is shown, comprising a frame 1, a laminating assembly 2, a guide mechanism 3, a pressure roller device 4, a motor 5, a drive shaft 6, and a rotary joint 7. The laminating assembly 2, the guide mechanism 3, and the pressure roller device 4 are arranged at the top of the frame 1, with the guide mechanism 3 and the pressure roller device 4 located on opposite sides of the laminating assembly 2. The motor 5 is arranged in the lower middle portion of the frame 1, and the drive shaft 6 connects the output end of the motor 5 to the laminating assembly 2. The motor 5 drives the laminating assembly 2 to rotate via the drive shaft 6. A control switch (not shown) for controlling the start and stop of the motor 5 is provided on the frame 1. The control switch of the motor 5 can be a manual switch or a foot-operated switch. The rotary joint 7 is connected to the bottom of the drive shaft 6, and various connecting wires are passed through the rotary joint 7 to prevent the connecting wires from getting tangled as the drive shaft 6 rotates.

[0035] like Figure 1 、 Figure 2 As shown, the laminating assembly 2 is fixedly connected to the drive shaft 6 via a base 21. Several linear guides 22 are circumferentially disposed on the base 21, and the linear guides 22 are arranged radially. Movable discs 23 are slidably mounted on the linear guides 22 via sliders. Several of the movable discs 23 are shaped like a disk. Each movable disc 23 is fixedly connected to a winding disc 24. Several of the winding discs 24 are shaped like a disk. The winding discs 24 are connected to the movable discs 23 via connecting keys 25. Each winding disc 24 has connecting slots 241 formed therein. The connecting keys 25 are inserted into the connecting slots 241 to position the winding discs 24. A first cylinder 26 is positioned in the center of the top surface of the base 21. The top of the piston rod of the first cylinder 26 is connected to a movable block 27, which is equipped with several pull rods 28. Each pull rod 28 corresponds to a movable disk 23. One end of the pull rod 28 is hinged to the movable block 27, and the other end is hinged to a connecting seat 29, which is fixed to the movable disk 23. The first cylinder 26 can be extended or retracted by pulling or pushing the movable disk 23 along the linear guide 22 via the pull rod 28, thereby driving the winding disk 24 to retract inward or expand outward. A switch (not shown) is provided on the frame 1 to control the extension and retraction of the first cylinder 26. The frame 1 can also be equipped with a pressure regulating device for the first cylinder 26 to adjust the pressure of the first cylinder 26.

[0036] like Figure 1As shown, the guide mechanism 3 is fixed to the frame 1 via a bracket 31. The bracket 31 is provided with a plurality of guide rollers 32 and a guide plate 33. The guide plate 33 is located on the side near the winding disk 24. Part of the guide plate 33 extends below the winding disk 24, and a certain vertical gap is left between the guide plate 33 and the winding disk 24. This ensures that the apex is better guided onto the winding disk 24 while avoiding interference with the movement of the winding disk 24. The first connecting hole 331 connecting the guide plate 33 to the bracket 31 is an arc-shaped elongated hole with sufficient adjustment space. The guide plate 33 can be adjusted according to actual conditions to better guide the apex onto the winding disk 24.

[0037] like Figure 1 As shown, the pressure roller device 4 is fixedly connected to the frame 1 through the support plate 41, and the support plate 41 is connected to the pressure roller assembly 42 and the fixing frame 43 through the connecting shaft 45; the second connecting hole 411 on the connecting shaft 45 connecting the support plate 41 is an oblong hole with an adjustment space to adjust the position of the pressure roller assembly 42. The pressure roller assembly 42 is hinged on the connecting shaft 45, and the fixing frame 43 is fixed on the connecting shaft 45. The second cylinder 44 is set on the fixing frame 43, and the piston rod of the second cylinder 44 is hinged to the pressure roller assembly 42. The second cylinder 44 can extend and retract to drive the pressure roller assembly 42 to compress or release the apex rubber. Figure 3 、 Figure 4 As shown, the pressure roller assembly 42 includes a C-shaped connecting plate 421. An adjustment plate 422 is provided at the upper end of the connecting plate 421. An adjustment shaft 423 is passed through the adjusting plate 422. A rollable pressure roller 424 is provided at the lower end of the adjusting shaft 423. A handwheel 425 is provided at the upper end of the adjusting shaft 423. A bearing is provided between the pressure roller 424 and the adjusting shaft 423. The adjustment plate 422 is connected to the connecting plate 421 via a connecting bolt 426, one end of which is provided with a handle 427. The adjustment hole 4221 connecting the adjustment plate 422 to the connecting plate 421 is an arc-shaped elongated hole with sufficient adjustment space. The handle 427 can be used to adjust the angle of the adjustment plate 422, thereby adjusting the angle of the pressure roller 424 to better press the pressure roller 424 onto the apex. The adjustment shaft 423 is threadedly connected to the adjusting plate 422. By turning the handwheel 425, the height of the adjustment shaft 423 can be adjusted, thereby adjusting the height position of the pressure roller 424. The lower end of the pressure roller 424 is provided with a conical surface 4241. This allows the pressure roller 424 to press against the apex, providing more stable and reliable pressure and facilitating the proper fit of the apex. The lower end of the connecting plate 421 is fitted with a hinge shaft 428 and a connecting sleeve 429. The piston rod of the second cylinder 44 is hinged to the hinge shaft 428, and the connecting shaft 45 is inserted into the connecting sleeve 429. A bearing is provided between the connecting shaft 45 and the connecting sleeve 429. A switch (not shown) is provided on the frame 1 to control the extension and retraction of the second cylinder 44. The frame 1 can also be equipped with a pressure regulating device for the second cylinder 44 to adjust the pressure therein.

[0038] The manual laminating machine 100 has a simple structure and is easy to operate, and is suitable for the production of unconventional tire rims with low demand or special specifications.

[0039] Figure 5 The figure shows a dual-station laminating device, comprising both manual and automatic gluing stations. A manual laminating machine 100 is positioned at the manual gluing station, while an automatic laminating machine 200 is positioned at the automatic gluing station. The manual and automatic laminating machines 100 and 200 are arranged side by side. A guide frame 300 is located atop the automatic laminating machine 200, from which the apex bead is fed to the manual laminating machine 100. The dual-station laminating device combines both manual and automatic gluing stations, allowing the appropriate station to be selected based on actual production requirements. The dual-station system can produce both general and specialized tire tire specifications, broadening its applicability and reducing equipment investment costs.
