Description

Technical Field

[0001] This utility model relates to the field of yarn changing in a doubling twister, and more particularly to a yarn changing device for a doubling twister. Background Technology

[0002] After spinning, the yarn bobbins on the take-up bar of the doubling machine need to be manually removed one by one by workers and placed into the handcart. However, due to the low height of the yarn bobbins, workers need to bend over to pick up the yarn, which causes significant damage to their backs over a long period of time. Therefore, based on this technical problem, we designed a yarn changing device for the doubling machine. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a yarn changing device for a doubling machine, including a take-up trolley, auxiliary take-up rollers, and a guide baffle. The main body of the take-up trolley is a trough structure that is completely penetrated from the top. Push wheels are arranged around the take-up trolley. Multiple auxiliary take-up rollers are arranged in a vertical array on one side of the take-up trolley. The auxiliary take-up rollers are arranged horizontally and are driven by a motor. The auxiliary take-up rollers are attached to the yarn bobbin of the doubling machine and lift the yarn bobbin upward. A guide baffle is provided above, which is inclined to guide the yarn bobbin to one side of the take-up trolley. The yarn bobbin that has detached from the take-up rod of the doubling machine is fed into the take-up trolley by inertia along the guide baffle.

[0004] There are three auxiliary take-up rollers. The height of the uppermost auxiliary take-up roller is higher than the height of the take-up bar of the twisting machine, and the height of the lowermost auxiliary take-up roller is at the middle of the yarn bobbin on the take-up bar of the twisting machine.

[0005] The auxiliary receiving roller on one side of the moving front end of the receiving trolley is provided with a conical guide surface to facilitate pushing in; the rotating shafts on both sides of the auxiliary receiving roller are rotatably limited on the bracket.

[0006] A gear is installed on the shaft of the uppermost auxiliary receiving roller that passes through the bracket on the side away from the conical guide surface. A gear is installed on the shaft of the motor. The two lower auxiliary receiving rollers are each equipped with two gears. The gears of the uppermost and middle auxiliary receiving rollers are driven by a chain. The other gear of the middle auxiliary receiving roller and one gear of the lower auxiliary receiving roller are driven by a chain. The other gear of the lower auxiliary receiving roller and the gear on the motor are driven by a chain.

[0007] A guide groove is provided on one side of the lower part of the twister along its length, and an opening is provided on one side of the upper part of the guide groove along its length. Multiple limiting bearings are provided on the side of the take-up trolley near the twister. The limiting bearings extend into the guide groove from one end of the guide groove and are limited to rolling. The limiting bearings are connected to the take-up trolley through the opening of the guide groove via a connecting rod in the shape of "┌".

[0008] The outer ring of the auxiliary receiving roller is made of rubber.

[0009] The beneficial effects of this utility model are as follows: Multiple upward-rolling auxiliary take-up rollers quickly deliver the yarn bobbin, which is then turned by a guide baffle and falls into the take-up trolley. The whole process is quick and efficient; a worker can complete the yarn collection by pushing the bobbin through one loop. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments: See Figure 1-5 .

[0014] This utility model discloses a yarn changing device for a doubling twister, including a take-up trolley 1, auxiliary take-up rollers 2, and a guide baffle 3. The main body of the take-up trolley is a trough structure that extends completely through the top. Pushing wheels 4 are arranged around the take-up trolley. Multiple auxiliary take-up rollers are arranged in a vertical array on one side of the take-up trolley. The auxiliary take-up rollers are horizontally arranged and driven by a motor 5. The auxiliary take-up rollers are attached to the yarn bobbin 7 of the doubling twister 6, lifting the yarn bobbin upward. A guide baffle is provided above, tilting towards one side of the take-up trolley. The yarn bobbin detached from the take-up rod 8 of the doubling twister is fed into the take-up trolley by inertia along the guide baffle. When the yarn bobbin 7 is pushed out of the take-up rod 8, it has a certain speed and is guided into the take-up trolley 1 by colliding with the guide baffle.

[0015] There are three auxiliary take-up rollers. The height of the uppermost auxiliary take-up roller is higher than the height of the take-up bar of the twisting machine, and the height of the lowermost auxiliary take-up roller is in the middle of the yarn bobbin on the take-up bar of the twisting machine. Since the yarn on the yarn bobbin 7 is wound in the middle, a little space is reserved at both ends where no yarn is spun. This arrangement of the auxiliary take-up rollers allows the yarn bobbin 7 to have a certain speed inertia when it moves out of the take-up bar 8.

[0016] The auxiliary take-up roller on one side of the moving front end of the take-up trolley is provided with a conical guide surface 9 to facilitate pushing in; the rotating shafts on both sides of the auxiliary take-up roller are rotatably limited on the bracket 10. Because the auxiliary take-up roller and the yarn bobbin are interference-fitted, pushing in directly in a loose state may cause jamming. Therefore, the conical guide surface 9 is provided to prevent this from happening.

[0017] A gear 11 is installed on the shaft of the uppermost auxiliary receiving roller that passes through the bracket on the side away from the conical guide surface. A gear is installed on the shaft of the motor. The two lower auxiliary receiving rollers are each equipped with two gears. The gears of the uppermost and middle auxiliary receiving rollers are driven by a chain. The other gear of the middle auxiliary receiving roller and one gear of the lower auxiliary receiving roller are driven by a chain 12. The other gear of the lower auxiliary receiving roller and the gear on the motor are driven by a chain 12.

[0018] A guide groove 13 is provided along the length of the lower side of the twister, and an opening 14 is provided along the length of the upper side of the guide groove. Multiple limiting bearings 15 are provided on the side of the take-up trolley near the twister. The limiting bearings extend into the guide groove from one end and are limited in their rolling motion. The limiting bearings are connected to the take-up trolley via a connecting rod 16 in a "┌" shape that passes through the opening of the guide groove. The limiting bearings 15 are engaged within the guide groove to prevent the take-up trolley from shifting.

[0019] The outer ring of the auxiliary take-up roller is made of rubber. The rubber material, combined with the elasticity of the yarn on the yarn bobbin, allows the auxiliary take-up roller and the yarn bobbin to be in an interference fit, increasing friction and thus quickly pushing the yarn bobbin out.

[0020] Specific usage: First, parallelize the take-up trolley 1 and the twister 6, insert the limit bearing 15 from one end of the guide groove 13, and push the take-up trolley 1; start the motor to drive the auxiliary take-up roller 2 to rotate quickly, and smoothly bring the yarn of the auxiliary take-up roller and the yarn bobbin together and quickly upward through the action of the conical guide surface 9. When the take-up rod 8 is separated from the take-up rod, it is quickly hit on the guide baffle and turns and falls into the take-up trolley 1.

[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
