Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber felt processing technology, specifically to a fiber open needle cloth that is easy to install. Background Technology
[0002] In industries such as textiles, papermaking, and fiber processing, fiber opening is a crucial step. It involves dispersing and fluffing tightly packed or tangled fiber bundles to facilitate subsequent processing.
[0003] Traditional fiber opening needle cloths often focus on the arrangement, shape, and material of the needle teeth to ensure that they can effectively act on the fibers and achieve the ideal opening effect. However, most existing fiber opening needle cloths adopt standardized size designs, that is, the width, length, and arrangement of the needle teeth of the needle cloth are fixed. Although this design is convenient for production and management, it brings great limitations in practical applications. This is because in actual production lines, the specifications of rollers often vary depending on the equipment model and production requirements. If the size of the needle cloth remains unchanged, it is difficult to achieve a perfect fit with all specifications of rollers.
[0004] When encountering rollers with large or small diameters, traditional fixed-size needle cloths are inadequate. If forced to install, the fit between the needle cloth and the roller may be loose, leading to problems such as loosening or misalignment, which in turn affects the opening and loosening effect. In addition, due to the loose fit, it may also increase the wear and noise of the equipment and reduce its service life.
[0005] Therefore, in response to the above problems, the applicant needs to design a fiber opening needle cloth that is easy to install to solve the problem. Utility Model Content
[0006] The purpose of this invention is to provide a fiber opening needle cloth that is easy to install, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a fiber opening needle cloth that is easy to install, comprising a fixing belt for being sleeved on the outside of a roller, and an opening needle being provided on the fixing belt.
[0008] It also includes: an adjustment mechanism installed on a fixed belt, the adjustment mechanism comprising a connecting belt, and the connecting belt being provided with a second loosening pin, the connecting belt being provided with a connecting strip, and the connecting strip being provided with a limiting hole;
[0009] An installation mechanism is provided on a fixed belt, and the installation mechanism includes a fixing block that is fixedly connected to the fixed belt. The fixing block has a slot, and a rotatable limiting block is provided inside the slot. The limiting block cooperates with the limiting hole to lock the fixed belt and the connecting belt.
[0010] Furthermore, a fixing nail is provided on the connecting belt, and one end of the fixing nail passes through the connecting belt and extends into the interior of the connecting belt.
[0011] The above structural design utilizes fixing nails to facilitate a secure connection between the connecting belt and the connecting strap.
[0012] Furthermore, a rotating block is fixedly provided on the limiting block, and a support ring is rotatably provided inside the rotating block.
[0013] Through the above structural design, the support ring facilitates the support of the rotating block and facilitates the directional rotation of the rotating block, which in turn drives the limiting block to rotate in the same direction.
[0014] Furthermore, a connecting rod is fixedly provided on the support ring, and the end of the connecting rod away from the support ring is fixedly connected to the inner wall of the fixing block.
[0015] The above structural design utilizes connecting rods to facilitate support of the support ring, thereby improving the stability of the support ring.
[0016] Furthermore, a reset spring is fixedly provided on one side of the limiting block, and a fixing post is fixedly provided at the end of the reset spring away from the limiting block, and the fixing post is fixedly connected to the fixing block.
[0017] With the above structural design, the return spring can easily push the limit block during use, and after the adjustment mechanism is installed, the return spring can easily push the limit block to lock the connecting belt, thereby firmly connecting the adjustment mechanism and the fixed belt.
[0018] Furthermore, the connecting strap is made of nylon fabric.
[0019] Through the above structural design, nylon fabric has high strength, which is three times that of viscose fiber. It can withstand greater tensile force without easily breaking. In addition, nylon fabric also has good fatigue resistance. Even under long-term repeated use, it can maintain good performance and is not prone to aging or damage.
[0020] Furthermore, both the first and second slugging needles are identical, and both the first and second slugging needles are provided with inclined surfaces, the angle between the inclined surfaces and the bottom surface of the slugging needles being in the range of 15° to 35°.
[0021] Through the above structural design, the angle and structure of the opening needles are better and more effective for the uniformity of the fibers formed by airflow web formation, thereby improving the opening degree.
[0022] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-install fiber opening needle cloth is equipped with an easy-to-install adjustment mechanism, which facilitates the change of the size and specifications of the opening needle cloth, thereby adapting to rollers of different specifications and having a wide range of applications. The specific details are as follows:
[0023] When using this easy-to-install fiber opening needle cloth, to expand the size of the opening needle cloth, external force is used to press the limiting block. The limiting block will push the return spring to move, and the return spring will generate elastic force. Then, the connecting belt is inserted into the fixing block through the limiting hole. After the connecting belt is installed, the external force is released from the limiting block, and the return spring will push the limiting block to spread out, which will facilitate the secure connection between the connecting belt and the fixing belt through the limiting hole. The installation is convenient, and the opening needle cloth of different sizes can be adapted to rollers of different sizes, making it widely applicable. Attached Figure Description

[0033] A fixing nail 23 is provided on the connecting belt 22, and one end of the fixing nail 23 passes through the connecting belt 22 and extends into the interior of the connecting belt 20. The fixing nail 23 facilitates a secure connection between the connecting belt 22 and the connecting belt 20.
[0034] A rotating block 33 is fixedly mounted on the limiting block 32, and a support ring 34 is rotatably mounted inside the rotating block 33. The support ring 34 facilitates the support of the rotating block 33 and allows the rotating block 33 to rotate in a specific direction. The rotation of the rotating block 33 will drive the limiting block 32 to rotate in a specific direction. A connecting rod 35 is fixedly mounted on the support ring 34, and the end of the connecting rod 35 away from the support ring 34 is fixedly connected to the inner wall of the fixed block 30. The connecting rod 35 facilitates the support ring 34 and improves the stability of the support ring 34. A return spring 36 is fixedly mounted on one side of the limiting block 32, and a fixing post 37 is fixedly mounted on the end of the return spring 36 away from the limiting block 32. The fixing post 37 is fixedly connected to the fixed block 30.
