Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] See Figures 1 to 5 According to an embodiment of this utility model, an automatic padding cloth feeding device is provided, including: a frame 1; a conveying assembly including a main shaft 2, a drive motor 3, and at least two sets of pressure rollers 4; the drive motor 3 is fixedly mounted on the frame 1, and the output end of the drive motor 3 is coaxially connected to the main shaft 2; the pressure rollers 4 are sleeved on the main shaft 2, and the pressure rollers 4 are provided with a conveying part 7 for contacting the padding cloth 100; a cutting mechanism including a blade holder 8, a cutting blade 9, and a cutting motor 14; the cutting blade 9 is movably connected to the blade holder 8; the cutting motor 14 is used to drive the cutting blade to move; wherein, the conveying part 7 is detachably connected to the pressure rollers 4.

[0022] Specifically, the frame 1 is equipped with bearings, and the main shaft 2 passes through the bearings; this provides rigid support for the entire device, ensuring stable operation of all components. The main shaft 2 is coaxially connected to the drive motor 3, enabling precise control of the conveying length of the pad 100, avoiding uneven fabric delivery caused by manual operation. Pressure rollers 4 are mounted on the main shaft 2, and multiple sets of pressure rollers synchronously transmit the pad, eliminating the problem of misalignment. The detachable conveyor 7 allows for easy replacement of the appropriate conveyor according to the pad thickness, improving versatility. The cutting motor 14 drives the cutting blade 9 to move, achieving fully automatic cutting and eliminating the risks of excessively long, excessively short, or fragmented residue caused by manual cutting.

[0023] By adopting the above configuration, the safety risks and quality defects of manual operation are completely eliminated through automated coordination of conveying and cutting. By replacing the conveyor section 7 with different specifications and adjusting the gap between the pressure roller 4 and the transfer plate 13 to accommodate padding cloth 100 of different thicknesses, the technical problem of low efficiency in the padding cloth application process during tire production in related technologies is solved.

[0024] Specifically, in the automatic padding fabric feeding device of this embodiment, the drive motor 3 controls the conveying length of the padding fabric 100 according to the tire parameters and the parameters of the padding fabric 100, and the pressure roller 4 conveys the padding fabric 100 to the cutting station of the cutting mechanism through the friction of the conveying part 7. The drive motor 3 controls the conveying length according to the tire parameters; thus, the conveying volume is accurately calculated by combining parameters such as tire diameter and padding fabric thickness, reducing plastic padding fabric waste. The conveying part 7 conveys the padding fabric through friction, ensuring that the padding fabric enters the cutting station flat and avoiding folding of the fabric or tilted cutting. In this way, the padding fabric conveying can be made more precise and adaptive, improving the yield rate of subsequent cutting processes.

[0025] In the automatic padding fabric feeding device of this embodiment, the tire parameters include the tire diameter. The tire diameter, as a core control parameter, is directly related to the circumference of the padding fabric roll, avoiding deviations in the bonding length caused by diameter estimation errors. Thus, using key parameters to drive the control logic improves system reliability.

[0026] See Figure 1 , Figure 2 In the automatic padding device of this embodiment, the output shaft of the cutting motor 14 is linked to the cutting blade 9 through the belt 10 to drive the cutting blade 9 to reciprocate.

[0027] With the above configuration, the cutting motor 14 is linked to the cutting blade 9 via the belt 10. The belt drive enables the cutting blade to reciprocate at high speed, ensuring a smooth, burr-free cut. This simplifies the transmission structure, improves cutting efficiency, and avoids the tilting problem caused by manual cutting.

[0028] See Figure 1 , Figure 2 In the automatic padding device of this embodiment, the cutting blade 9 is a wallpaper blade; the cutting blade 9 is detachably fixed to the back plate of the blade holder 8 by a self-locking screw 11 and a locking piece 12; the cutting motor 14 drives the blade holder 8 to reciprocate radially along the main shaft 2.

[0029] Specifically, the cutting blade 9 uses a wallpaper blade, which is inexpensive and easy to replace. The cutting blade is secured by a self-locking screw 11 and a locking plate 12, enabling quick blade removal and installation, improving maintenance efficiency by 50%. The blade holder 8 moves radially along the main shaft, ensuring the cutting blade covers the full width of the padding cloth, preventing missed cuts. This balances economy and maintainability, reducing long-term operating costs.

[0030] In the automatic pad feeding device of this embodiment, the conveying part 7 is made of rubber. The rubber material of the conveying part 7 provides high friction without damaging the surface of the pad, and the gap between it and the transfer plate 13 is adaptively adjusted by the rubber's elasticity. This ensures the conveying stability of pads of different thicknesses and eliminates the risk of slippage. Preferably, a sealing ring can be used.

[0031] In the automatic padding cloth feeding device of this embodiment, the cutting blade 9 has a blade length greater than the padding cloth width of 100mm; the back plate of the blade holder 8 is provided with a through-type sliding groove, and the locking plate 12 is adjustable along the sliding groove by means of a self-locking screw 11.

[0032] Specifically, the cutting blade 9 has a blade length greater than the width of the padding fabric, ensuring a complete cut in one go. The locking plate 12 can be adjusted to accommodate padding fabrics of different widths, increasing the device's flexibility. This solves the problem of leftover fragments caused by insufficient width adaptation during manual cutting.

[0033] The automatic pad feeding device in this embodiment also includes safety protection components, including an infrared sensor and an emergency stop switch; the infrared sensor is installed above the pressure roller 4, and the emergency stop switch is electrically connected to the drive motor 3.

[0034] Specifically, an infrared sensor monitors the area above pressure roller 4, detecting foreign object intrusion in real time and triggering an emergency stop. The emergency stop switch, in conjunction with the drive motor, can cut off power in a short time, completely eliminating the risk of entanglement. This achieves proactive safety protection and meets safety production standards.

[0035] In the automatic pad feeding device of this embodiment, the outer surface of the pressure roller 4 is recessed with a groove 19; the groove 19 is arranged around the pressure roller 4; the conveying part 7 is arranged in the groove 19.

[0036] Specifically, the pressure roller 4 has an annular groove 19 on its surface to limit the radial displacement of the transmission part 7 and prevent it from falling off during operation. The transmission part 7 is embedded in the groove 19 to improve transmission stability and reduce pad shifting caused by vibration. This enhances the reliability of the mechanical coupling between the pressure roller and the transmission part.

[0037] In the automatic pad feeding device of this embodiment, the conveying part 7 includes a mounting part 71 disposed in the groove 19 and a contact part 72 located outside the groove 19; the contact part 72 has a contact surface 721 for contacting the pad 100; the contact surface 721 is a curved surface.

[0038] Specifically, the contact surface 721 of the conveying part 7 is curved, increasing the contact area with the pad 100 and evenly distributing the friction force. The mounting part 71 is confined within the groove to prevent the rubber ring from moving radially during operation. By adopting the above configuration, the force distribution on the pad can be optimized, avoiding slippage or tearing caused by localized wear.

[0039] The automatic padding device in this embodiment operates as follows: 1. Secure the cutting blade 9 to the blade holder 8; 2. Insert the beginning of the plastic pad into the equipment; 3. The drive motor 3 drives the main shaft 2 to rotate, and at the same time drives the pressure roller 4 to rotate, which in turn drives the plastic pad forward by friction. 4. After the plastic pad has completely passed through the wheel device, after a certain period of time, the blade holder 8 drives the cutting blade 9 to move and quickly cut the pad to complete the bonding.
