Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile equipment, and particularly relates to an anti-slip traction mechanism. Background Art
[0002] The pilot machine is a test equipment that simulates the production of dipped cords. It is built in the open space of the factory workshop. It has the advantages of small equipment, compact structure and fast production. It can quickly produce small quantities of test products, so as to improve and adjust the production process of dipped cords while saving production materials.
[0003] The production process of the pilot machine is basically pulling-dipping-drying-dipping-drying-winding. The current way of feeding the yarn is to use the rotation of the light roller to pull the yarn to move. This method can effectively protect the yarn, but because the production volume of the pilot machine is small, generally only 8-12 yarns, the density between the yarns is small during pulling, the tension of the yarn itself is small, and the friction between the yarn and the light roller is small, so it is easy to slide horizontally and entangle with each other, causing breakage, or slide longitudinally and cause uneven feeding. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides an anti-slip traction mechanism.
[0005] The technical solution adopted by the utility model is an anti-slip traction mechanism, including a first traction roller arranged at the front end of a dipping machine and a second traction roller arranged at the front end of a winding machine, a plurality of wire grooves are evenly spaced on the surfaces of the first traction roller and the second traction roller, and the cross-section of the wire groove is V-shaped, and the yarn is located in the wire groove and passes around the first traction roller and the second traction roller.
[0006] Preferably, a rubber layer is provided on the surface of the wire trough.
[0007] Preferably, the depth of the wire groove is 3-6 mm, and the angle is 40°-50°.
[0008] Preferably, a third traction roller, a fourth traction roller and a fifth traction roller are arranged side by side between the first traction roller and the second traction roller, wire grooves are opened on the surfaces of the third traction roller and the fifth traction roller, the fourth traction roller is a smooth roller, and the diameters of the third traction roller, the fourth traction roller and the fifth traction roller are all 200 mm.
[0009] Preferably, the ends of the rotating shafts of the third traction roller, the fourth traction roller and the fifth traction roller are all engaged with the chain through a sprocket, and the chain is connected to the rotating motor.
[0010] Compared with the prior art, the beneficial effect of the present invention is that the present invention respectively arranges a first traction roller and a second traction roller with wire grooves at the front and rear ends of the entire process equipment to pull the yarn forward. The wire grooves are V-shaped and the surface is covered with a rubber layer, which has a certain clamping and separation effect on the yarn, preventing the yarn from slipping longitudinally and transversely during the feeding process, solving the problem of yarn breakage or longitudinal slippage and uneven feeding caused by yarn transverse slippage and entanglement, which is beneficial to maintaining stable feeding of the process. At the same time, the third, fourth and fifth traction rollers are arranged in the middle of the entire process, and the three rollers are used to supplement traction, which avoids stagnation of yarn feeding and has the effect of balancing tension, further promoting yarn tensioning, and is beneficial to subsequent yarn feeding.

[0014] The present invention will be further explained below with reference to the accompanying drawings to facilitate better understanding by those skilled in the art.
[0015] Example 1
[0016] like Figure 1-3 As shown, an anti-slip traction mechanism includes a first traction roller 1, a second traction roller 2, a third traction roller 3, a fourth traction roller 4 and a fifth traction roller 5. The first traction roller 1 is arranged at the front end of the dipping machine, the second traction roller 2 is arranged at the front end of the winding machine, the third traction roller 3, the fourth traction roller 4 and the fifth traction roller 5 are arranged side by side and arranged between the first traction roller 1 and the second traction roller 2 (mainly arranged between the first dryer and the second dipping machine). A plurality of wire grooves 6 are evenly spaced on the surfaces of the first traction roller 1, the second traction roller 2, the third traction roller 3 and the fifth traction roller 5. The cross-section of the wire groove 6 is V-shaped. The yarn is located in the wire groove 6 and passes around the first traction roller 1, the second traction roller 2, the third traction roller 3 and the fifth traction roller 5. The fourth traction roller 4 is a smooth roller. The diameters of the third traction roller 5, the fourth traction roller 4 and the fifth traction roller 6 are all 200 mm.
[0017] The first traction roller 1 and the second traction roller 2 provided with wire grooves 6 are respectively provided at the front and rear ends of the entire process equipment to pull the yarn forward. The wire grooves 6 are V-shaped and have a certain clamping effect on the yarn to prevent the yarn from slipping in the longitudinal and transverse directions during the feeding process, solving the problem of yarn breakage caused by lateral slippage and entanglement or uneven feeding caused by longitudinal slippage, which is conducive to maintaining the stability of the process feeding. At the same time, the third, fourth and fifth traction rollers are provided in the middle of the entire process. The three rollers are used to supplement the traction, avoid the yarn from stagnating in the feeding, and have the effect of balancing the tension, further promoting the tension of the yarn, which is conducive to the subsequent feeding of the yarn. Among them, the third and fifth traction rollers have wire grooves, and the fourth traction roller is a smooth roller, which has a buffering effect on the yarn to avoid yarn breakage caused by excessive tension.
[0018] In order to increase the friction between the yarn and the groove 6 and prevent the groove 6 from damaging the yarn, a rubber layer 7 is provided on the surface of the groove 6; the groove 6 has a depth of 3-6mm and an angle of 40°-50°, which is suitable for the production of products of most specifications.
[0019] The ends of the rotating shafts of the third traction roller 3, the fourth traction roller 4 and the fifth traction roller 5 are all engaged with the chain through a sprocket, and the chain is connected to the rotating motor. The rotating motor is uniformly used to drive the third traction roller, the fourth traction roller and the fifth traction roller to rotate at the same time and maintain synchronous rotation.
[0020] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications and improvements made by those skilled in the art to the technical solution of the present invention without departing from the spirit and principles of the present invention shall fall within the scope of protection defined by the claims of the present invention.
