Description

Technical Field

[0001] This utility model relates to the field of tire component production equipment, specifically to a soft connection hook unloading device for tire bead laying. Background Technology

[0002] The tire bead is a key component of a tire, primarily used in radial tires to secure the tire to the rim. The tire bead typically consists of a steel wire ring and a triangular rubber strip. The steel wire ring and triangular rubber strip are bonded together on a bonding machine. The bonded tire bead, commonly known as a bead lay-up, needs to be orderly stacked with the spacer ring using a gripping mechanism. Currently, the hook-and-grip device for bead lay-up consists of a guide rod, upper cylinder, lower cylinder, cylinder connector, slider, linear bearing, rigid hook fixing seat, and hook. The hooking and unloading action is completed by detecting the upper, middle, and lower position proximity switches. Due to the complexity of this structure, frequent equipment failures occur when the hook reaches the rotating frame chain section due to inaccurate positioning of the rotating frame or photoelectric position misalignment. The hook gets tangled in the chain, causing cascading damage to the cylinder, guide rod, linear bearing, slider, and other components, resulting in unnecessary waste, production interruptions, and a significant reduction in production efficiency.

[0021] The present invention will now be described in detail with reference to the embodiments and accompanying drawings. Example 1

[0022] See Figure 1 and Figure 2 A flexible hook unloading device for tire bead siding includes an upper cylinder, a lower cylinder, a left guide rod, a right guide rod, a slider 1, and a hook 7. The piston rods of the upper and lower cylinders are connected vertically. The slider is fixed to the lower cylinder and slides up and down along the left and right guide rods. This is the existing structure and will not be described in detail here. Importantly, this device also includes an upper fixed seat 3, a lower fixed seat 6, a central connecting spring 12, and a central safety pin 11. The upper fixed seat 3 is fixed to the lower part of the slider 1, and the upper part of the hook 7 is fixed to the lower part of the lower fixed seat 6. All fixed seats 6 are cylindrical. The upper fixed seat 3 and the lower fixed seat 6 are assembled in a corresponding split manner. The central connecting spring 12 is arranged inside the upper fixed seat 3 and the lower fixed seat 6. The axis of the central connecting spring 12 is consistent with the axis of the upper fixed seat 3 and the lower fixed seat 6. The central safety pin 11 is arranged inside the central connecting spring 12. The axis of the central safety pin 11 is consistent with the axis of the central connecting spring 12. The upper ends of the central connecting spring 12 and the central safety pin 11 are fixed to the upper fixed seat 3, and the lower ends of the central connecting spring 12 and the central safety pin 11 are fixed to the lower fixed seat 6. Example 2

[0023] See Figure 1 and Figure 2 A flexible hook unloading device for tire bead siding, based on the technical solution described in Example 1, features a hollow safety pin 11, which is more easily broken under tension to better serve its safety function. The central safety pin 11 is made of nylon, also known as polyamide fiber, which is non-toxic, lightweight, easy to process and mold, and has excellent mechanical strength, wear resistance, and corrosion resistance. Example 3

[0024] See Figure 1 and Figure 2 A flexible hook unloading device for tire bead siding, based on the technical solution described in Embodiment 1, wherein the upper ends of the central connecting spring 12 and the central safety pin 11 are fixed to the upper fixing seat 3 by screws 4; the upper fixing seat 3 is provided with two threaded holes 5 arranged vertically for tightening the screws 4; the lower ends of the central connecting spring 12 and the central safety pin 11 are fixed to the lower fixing seat 6 by screws 4; the lower fixing seat 6 is provided with two threaded holes 5 arranged vertically for tightening the screws 4. The screws 4 are preferably hexagonal socket head cap screws for easy operation with a wrench. The two threaded holes 5 facilitate adjustment of the screw 4 position. Example 4

[0025] See Figure 1 and Figure 2A flexible hook unloading device for tire bead slats, based on the technical solution described in Embodiment 1, wherein the upper fixed seat 3 is fixed to the lower part of the slider 1 by a fixed plate 2, and the upper fixed seat 3 and the fixed plate 2 are connected by a horizontal tube 10 to enhance the firmness and operability. Example 5

[0026] See Figure 1 and Figure 2 A flexible hook unloading device for tire bead siding, based on the technical solution described in Example 1, wherein the upper part of the hook 7 is fixed to the lower part of the lower fixing seat 6 by welding to enhance its firmness.

[0027] The basic working principle of this utility model is as follows:

[0028] The present invention is assembled according to the above technical solution. The fixed positions of the central connecting spring 12 and the central safety pin 11 can be flexibly controlled by adjusting the installation positions of the adjusting screw 4 in the two threaded holes 5 of the upper fixed seat 3 and the two threaded holes 5 of the lower fixed seat 6. Under the combined drive of the upper and lower cylinders, the slider 1 slides up and down along the left and right guide rods, and the hook 7 moves up and down accordingly, sequentially completing the tasks of hooking the tire bead liner 9 and releasing the tire bead liner 9 onto the two conveyor chains 8. Under normal working conditions, the hook 7 is in the middle position of the two conveyor chains 8. During the unloading process, it will not get stuck on the conveyor chains 8, but will rise to complete the subsequent cyclic hooking and unloading tasks. When in abnormal working condition, hook 7 is significantly deviated from the middle position of the two conveyor chains 8. During the unloading process, it gets stuck on one of the conveyor chains 8. Since hook 7 is welded to the lower fixed seat 6 and the upper fixed seat 3 and the lower fixed seat 6 are separate structures, the lower fixed seat 6 is also pulled. The central safety pin 11 breaks first during the pulling process, and then the central connecting spring 12 is stretched obliquely to prevent damage to the lower fixed seat 6 and the slider 1 and other components. After replacing the central safety pin 11, it can operate normally again.
