Description

Technical Field

[0001] This utility model relates to the technical field of feeding and testing equipment, specifically to an automatic feeding and testing device for abrasive cloth used in the production of leaf rollers. Background Technology

[0002] In the manufacturing process of polishing wheels (blades), abrasive cloth, as the main substrate, needs to undergo multiple processes such as cutting, layering, sewing, or bonding to form its shape. During continuous feeding or winding, if a break in the thread or the end of the abrasive cloth is encountered, it needs to be detected promptly and the equipment stopped to avoid material waste, processing defects, or equipment idling. Traditional detection methods, such as optical sensors, cannot reliably detect the abrasive cloth due to its characteristics. Therefore, an automatic abrasive cloth feeding detection device for blade wheel production is proposed to solve this problem. Utility Model Content

[0003] In view of this, the present invention provides an automatic detection device for feeding abrasive cloth in the production of flap wheels. The present invention can make the moving contact structure and the stationary contact structure electrically connected to the control box contact by rotating the swing arm structure, thereby controlling the equipment to stop when the wire is broken or the end is reached.

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic detection device for feeding abrasive cloth in the production of flap wheels, including a control box, a side liner plate on the control box, a swing arm structure rotatably mounted on the side liner plate, a moving contact plate structure that follows the movement of the swing arm structure, and a stationary contact plate that matches the moving contact plate structure on the side liner plate. Both the moving contact plate structure and the stationary contact plate are electrically connected to the control box.

[0005] The swing arm structure includes a rotating shaft rotatably mounted on a side liner plate. The corresponding side liner plate is provided with a mounting hole that matches the rotating shaft. A bearing assembly is provided in the mounting hole. A swing rod is provided at one end of the rotating shaft, and a moving contact plate structure is installed at the other end. A roller assembly is provided on the other side of the swing rod.

[0006] The rotating shaft has a spline at one end of the moving contact piece. The moving contact piece structure includes a key sleeve mounted on the spline, and the key sleeve has a contact piece body.

[0007] The rotating shaft has a fastening bolt at one end of the spline, and the corresponding rotating shaft has a threaded hole at that end that matches the fastening bolt.

[0008] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0009] 1. The rotation of the swing arm structure causes the moving contact structure and the stationary contact structure of the control box electrical connection to come into contact, thereby stopping the control equipment when the wire is broken or the end is reached.

[0010] 2. The spline and key sleeve allow the contact body to rotate stably with the rotating shaft, thus avoiding slippage and resulting detection problems. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] The effect of this utility model solution is as follows: Figure 1-3 As shown: It includes a control box 1, a side plate 2 on the control box 1, a swing arm structure 3 rotatably mounted on the side plate 2, a moving contact structure 4 that follows its movement on the swing arm structure 3, and a stationary contact 5 that matches the moving contact structure 4 on the side plate 2. Both the moving contact structure 4 and the stationary contact 5 are electrically connected to the control box 1.

[0018] like Figure 1-3 As shown, the swing arm structure 3 includes a rotating shaft 31 rotatably mounted on the side liner 2. The corresponding side liner 2 is provided with a mounting hole 21 that matches the rotating shaft 31. A bearing assembly 22 is provided in the mounting hole 21. A swing rod 32 is provided at one end of the rotating shaft 31, and a moving contact plate structure 4 is installed at the other end. A roller assembly 33 is provided on the other side of the swing rod 32.

[0019] like Figure 1-3As shown, the rotating shaft 31 has a spline 311 at one end where the moving contact is mounted. The moving contact structure 4 includes a key sleeve 41 mounted on the spline 311. The key sleeve 41 has a contact body 42. The spline 311 and the key sleeve 41 work together to ensure that the contact body 42 can stably follow the rotating shaft 31 to rotate, thereby avoiding slippage and resulting in poor detection.

[0020] like Figure 1-3 As shown, the rotating shaft 31 has a fastening bolt 6 at one end of the spline 311, and the corresponding rotating shaft 31 has a threaded hole 312 at the same end that matches the fastening bolt 6.

[0021] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
