Description

Technical Field

[0001] This utility model relates to the technical field of fancy twisting machines, specifically to an output roller of a fancy twisting machine. Background Technology

[0002] The output roller of a fancy twisting machine plays a crucial role. It works in conjunction with other components to ensure that the yarn is output at a stable speed and with appropriate tension.

[0003] According to CN206502910U, a technical solution disclosed in this paper is as follows: "It includes a roller core, and an output sleeve is sleeved on the outside of the roller core. The output sleeve includes a left half for outputting cotton fiber fancy yarn and a right half for outputting chemical fiber fancy yarn. Both ends of the roller core are coaxially provided with a rotation center shaft. The positioning grooves at both ends of the roller core are symmetrically distributed. That is, when two symmetrical positioning grooves are selected to position the fixing frame, the rotation center line of the two positioning grooves is located at the center line of the roller core. When the left half of the yarn needs to be used, a positioning groove away from the left half of the yarn is selected on the rotation center shaft near the left half of the yarn, and a positioning groove near the right half of the yarn is selected on the rotation center shaft near the right half of the yarn. At this time, the rotation centers of the two fixing frames are located on the left half of the yarn, ensuring dynamic balance at the left half of the yarn."

[0004] Although the above design has two different output sleeves on the roller, which can make the yarn even and improve the quality of fancy yarn, the surface will gradually wear down due to continuous friction and pressure during long-term twisting. The anti-slip protrusions on the outer surface of the roller core make it inconvenient to disassemble and replace the left and right halves, reducing the effectiveness of the device. Therefore, we propose an output roller for fancy twisting machines to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an output roller for a fancy twisting machine. This solves the problem that during long-term twisting operations, the surface will gradually wear down due to continuous friction and pressure, and the anti-slip protrusions on the outer surface of the roller core make it inconvenient to disassemble and replace the left and right halves, thus reducing the effectiveness of the device.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an output roller of a fancy twisting machine, including a central shaft and a roller core rotatably connected to the central shaft via bearings, wherein the outer surface of the roller core is fitted with symmetrically arranged roller sleeves;

[0007] The roller core is equipped with a disassembly and assembly mechanism that can lock the roller sleeve. The roller sleeve can be easily disassembled and assembled through the disassembly and assembly mechanism. The two sets of roller sleeves are divided into a left half and a right half.

[0008] Preferably, the disassembly and assembly mechanism includes two sets of locking pins arranged symmetrically inside the roller core near the rubber roller sleeve, and a locking groove formed on the inner side wall of the rubber roller sleeve that matches the locking pins, wherein a rack is fixed inside the locking pin;

[0009] Inside the roller core, near the side of the rubber roller sleeve, there is a symmetrically arranged rotating rod connected to the roller core via a bearing. A gear that meshes with a rack is fixed on the surface of the rotating rod. A rectangular hole is opened inside the locking pin. The gear and rack are located in the rectangular hole of the locking pin. A square rod is fixed to one end of the rotating rod. A rotating disk slides on the surface of the square rod. A symmetrically arranged locking strip is fixed on the surface of the rotating disk. A fixed disk is fixed on the surface of the square rod. A spring is fixed between the fixed disk and the rotating disk.

[0010] Preferably, a circular groove adapted to the rotating disk is provided on one side of the roller core, and a limiting groove adapted to the card strip is provided on the side of the roller core near the circular groove. The rotating disk slides on the square rod through the through hole.

[0011] Preferably, the surface of the roller core is provided with a movable groove adapted to the locking pin, and the locking pin and the roller core are slidably connected through this movable groove.

[0012] Preferably, a limiting rod is fixed to the outer surface of the locking pin, and a groove adapted to the limiting rod is opened inside the roller core. The limiting rod and the roller core are slidably connected through the limiting groove.

[0013] Preferably, the limiting rod slides within the limiting groove to limit the angle of the locking pin.

[0014] Beneficial effects

[0015] This invention provides an output roller for a fancy twisting machine. Compared with the prior art, it has the following advantages:

[0016] When the locking pin of the output roller of this fancy twisting machine is not moved, the locking pin is inserted into the locking groove inside the roller sleeve, which is equivalent to an anti-slip protrusion. When the locking pin moves, it disengages from the locking groove, thereby releasing the locking of the roller sleeve, which makes it easier to disassemble and replace the roller sleeve. This structure has higher disassembly efficiency and improves the use effect of the device. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 As shown:

[0023] An output roller of a fancy twisting machine includes a central shaft 101 and a roller core 102 rotatably connected to the central shaft 101 via bearings.

[0024] In this implementation plan: The existing device {publication (announcement) number}: CN206502910U discloses an output roller for a fancy twisting machine. To solve the technical problems existing in this prior art, as disclosed in the background art above, "When the above design is used, although the roller is equipped with two different output sleeves, the output can make the yarn uniform and improve the quality of fancy yarn. However, during long-term twisting work, due to continuous friction and pressure, the surface will gradually wear down. The outer surface of the roller core 102 is provided with anti-slip protrusions, which makes it inconvenient to disassemble and replace the left and right halves, reducing the effectiveness of the device." In terms of use, this problem is obviously a real and difficult problem to solve.

[0025] Furthermore:

[0026] like Figures 1-3 As shown:

[0027] In summary: the outer surface of the roller core 102 is fitted with symmetrically arranged rubber roller sleeves 103;

[0028] The roller core 102 is equipped with a disassembly and assembly mechanism 2 that can lock the roller sleeve 103. The roller sleeve 103 can be easily disassembled and assembled through the disassembly and assembly mechanism 2. The two sets of roller sleeves 103 are divided into a left half and a right half.

[0029] The disassembly and assembly mechanism 2 includes two sets of locking pins 201 arranged symmetrically inside the roller core 102 near the roller sleeve 103, and a locking groove 207 that is adapted to the locking pins 201 on the inner side wall of the roller sleeve 103. A rack 202 is fixed inside the locking pins 201.

[0030] Inside the roller core 102, near the side of the rubber roller sleeve 103, there are symmetrically arranged rotating rods 204 rotatably connected by bearings. The surface of the rotating rod 204 is fixed with a gear 203 that meshes with the rack 202. The locking pin 201 has a rectangular hole inside, and the gear 203 and rack 202 are located in the rectangular hole of the locking pin 201. One end of the rotating rod 204 is fixed with a square rod 212. A rotating disk 208 slides on the surface of the square rod 212. The surface of the rotating disk 208 is fixed with symmetrically arranged locking strips 209. The surface of the square rod 212 is fixed with a fixing disk 211. A spring 210 is fixed between the fixing disk 211 and the rotating disk 208.

[0031] A circular groove adapted to the rotating disk 208 is provided on one side of the roller core 102, and a slot adapted to the card strip 209 is provided on the side of the roller core 102 near the circular groove. The rotating disk 208 slides on the square rod 212 through the through hole, and the through hole has a square structure.

[0032] The surface of the roller core 102 is provided with a movable groove that matches the locking pin 201, and the locking pin 201 and the roller core 102 are slidably connected through this movable groove.

[0033] In this implementation scheme: When the output roller of the fancy twisting machine needs to be disassembled due to wear of the roller sleeve 103, the rotating disk 208 is first pulled, causing it to slide on the square rod 212. The rotating disk 208 stretches the spring 210 until it drives the locking strip 209 to disengage from the circular groove and the locking slot in the roller core 102, respectively. Then, the rotating disk 208 is rotated, which in turn drives the rotating rod 204 to rotate. As the rotating rod 204 rotates, it drives the gear 203 to rotate. Since the gear 203 and the rack 202 are meshed, the rack 202 is moved, causing the rack 202 to move the locking pin 201, thus moving the rotating disk 208. The moving locking bar 209 is rotated 180°, and then the rotating disk 208 is released. At this time, the spring 210 rebounds and contracts, driving the rotating disk 208 and the locking bar 209 to re-insert into the circular groove and the locking slot. At this time, the locking pin 201 disengages from the locking groove 207 opened in the roller sleeve 103, thereby releasing the lock on the roller sleeve 103. Through this operation, when the locking pin 201 is not moving, the locking pin 201 is inserted into the locking groove 207 inside the roller sleeve 103, which is equivalent to an anti-slip protrusion. When the locking pin 201 moves, it disengages from the locking groove 207, thereby releasing the lock on the roller sleeve 103, which facilitates the disassembly and replacement of the roller sleeve 103. This structure has higher disassembly efficiency and improves the use effect of the device.

[0034] Furthermore;

[0035] In an optional embodiment, a limiting rod 205 is fixed to the outer surface of the locking pin 201, and a limiting groove 206 adapted to the limiting rod 205 is provided inside the roller core 102. The limiting rod 205 and the roller core 102 are slidably connected through the limiting groove 206.

[0036] The limiting rod 205 slides within the limiting groove 206, which can limit the angle of the locking pin 201.

[0037] In this embodiment: while the locking pin 201 moves, it drives the limiting rod 205 to slide in the limiting groove 206. By setting the limiting rod 205, the locking pin 201 can be limited, thereby preventing the locking pin 201 from rotating and affecting the meshing effect of the rack 202 and the gear 203, and further improving the use effect of the device.

[0038] The working principle and usage process of this utility model: When the output roller of this fancy twisting machine needs to be disassembled due to wear of the roller sleeve 103, firstly, pull the rotating disk 208, causing it to slide on the square rod 212. The rotating disk 208 stretches the spring 210 until it drives the locking strip 209 to disengage from the circular groove and the locking slot opened in the roller core 102, respectively. Then, rotate the rotating disk 208, which in turn drives the rotating rod 204 to rotate. As the rotating rod 204 rotates, it drives the gear 203 to rotate. Since the gear 203 and the rack 202 are meshed, the rack 202 moves, causing the locking pin 201 to move, thus moving the rotating disk... 208 drives the locking strip 209 to rotate 180°, and then releases the rotating disk 208. At this time, the spring 210 rebounds and contracts, and drives the rotating disk 208 and the locking strip 209 to re-insert into the circular groove and the slot. At this time, the locking pin 201 disengages from the locking groove 207 opened in the roller sleeve 103, thereby releasing the lock on the roller sleeve 103. Through this operation, when the locking pin 201 does not move, the locking pin 201 is inserted into the locking groove 207 inside the roller sleeve 103, which is equivalent to an anti-slip protrusion. When the locking pin 201 moves, it disengages from the locking groove 207, thereby releasing the lock on the roller sleeve 103, which facilitates the disassembly and replacement of the roller sleeve 103. This structure has higher disassembly efficiency and improves the use effect of the device.
