Description

Technical Field

[0001] The utility model belongs to the technical field of yarn clamps, and particularly relates to a wear-resistant yarn clamp. Background Art

[0002] Textile machinery refers to various mechanical equipment required to process natural fibers or chemical fibers into textiles. Although the machinery for producing chemical fibers includes various chemical engineering machinery, it is now considered an extension of textile machinery and belongs to the broad sense of textile machinery. The processes required to process different fibers such as cotton, linen, silk, and wool into textiles are not all the same, and some are completely different, so the required machines are also various and numerous. Textile machinery is usually classified according to the production process, including: spinning equipment, weaving equipment, printing and dyeing equipment, finishing equipment, chemical fiber spinning equipment, silk reeling equipment, and non-woven fabric equipment. Among them, the yarn clamp is an important component in textile machinery, mainly used for clamping and guiding the yarn to ensure that the yarn can be stably and smoothly transmitted during the textile process.

[0003] At present, during the use of the existing yarn clamp, a connecting sleeve is usually sleeved on its outer wall, and after connection, the yarn clamp still needs to be driven to rotate to guide the yarn. However, after long-term use, the contact surface on the outer wall of the yarn clamp is prone to wear. When there is wear on the outer wall of the yarn clamp, the worn yarn clamp may be affected during the process of guiding the yarn, resulting in a reduction in textile processing efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wear-resistant yarn clamp, aiming to solve the problem that during the use of the existing yarn clamp, a connecting sleeve is usually sleeved on its outer wall, and after connection, the yarn clamp still needs to be driven to rotate to guide the yarn. However, after long-term use, the contact surface on the outer wall of the yarn clamp is prone to wear. When there is wear on the outer wall of the yarn clamp, the worn yarn clamp may be affected during the process of guiding the yarn, resulting in a reduction in textile processing efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A wear-resistant yarn clamp includes a yarn clamp body. A groove is provided on the outer wall of the yarn clamp body, and an annular slot is provided at the top of the yarn clamp body. A wear-resistant sleeve is inserted into the annular slot.

[0006] Two clamping grooves are provided on the outer wall of the wear-resistant sleeve. Two pull rods are inserted through the outer wall of the yarn clamp body. One end of each of the two pull rods is connected to a connecting block. One end of the connecting block is connected to a clamping pin. Springs are sleeved on the outer walls of the two pull rods. The ends of the two pull rods away from the connecting blocks are connected to a pulling block.

[0007] Preferably, as a wear-resistant yarn clip of the utility model, the two card slots are symmetrically distributed on the outer wall of the wear-resistant sleeve.

[0008] Preferably, as a wear-resistant yarn clip of the utility model, one end of the pin penetrates and extends into the internal of the annular slot.

[0009] Preferably, as a wear-resistant yarn clip of the utility model, the wear-resistant sleeve is sleeved on the outer wall of the yarn clip body.

[0010] Preferably, as a wear-resistant yarn clip of the utility model, the wear-resistant sleeve can form an elastic clamping structure with the yarn clip body through the annular slot, card slot, pull rod, connecting block, pin, spring and pull block.

[0011] Preferably, as a wear-resistant yarn clip of the utility model, the size of the annular slot is adapted to one end of the wear-resistant sleeve.

[0012] Preferably, as a wear-resistant yarn clip of the utility model, the wear-resistant sleeve is made of aluminum alloy.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By pulling the pull rod through the pull block, the connecting block drives the pin to contract. At this time, the wear-resistant sleeve is sleeved on the outer wall of the yarn clip body, and the wear-resistant sleeve is inserted into the internal of the annular slot. Then, by rotating the wear-resistant sleeve, the card slot on its outer wall can correspond to the position of the pin. After the correspondence, the pin will be inserted into the card slot on the outer wall of the wear-resistant sleeve under the action of the spring. At this time, the wear-resistant sleeve can be fixedly sleeved on the outer wall of the yarn clip body, thereby improving the wear resistance of the yarn clip body by using the wear-resistant sleeve made of aluminum alloy, and at the same time improving the service life of the yarn clip body and reducing the occurrence of situations affecting work efficiency.
