Description

Technical Field

[0001] This utility model relates to the field of wire feeding frame technology, specifically a wire feeding frame that facilitates the disassembly of the wire feeding roller. Background Technology

[0002] The pressure roller frame of an extra-large yarn take-up machine is an important component used in extra-large yarn take-up machines. It is mainly used to control the tension and winding process of yarn or wire. When winding the wire, a wire release frame is used. The winding of the wire can be completed by rotating the wire release roller on the wire release frame.

[0003] A wire feeding frame is a device for winding and unwinding wire. In existing wire feeding frames, when disassembling the wire feeding roller, the drive device moves the brackets and connecting shafts on both sides of the wire feeding roller to disengage it from the wire feeding roller, and then the wire feeding roller is removed. However, this method of disassembling the wire feeding roller requires personnel to support it from the bottom, otherwise the wire feeding roller will fall directly. This method of disassembling the wire feeding roller is cumbersome and inconvenient for disassembling the wire feeding roller on the wire feeding frame. Utility Model Content

[0004] The purpose of this invention is to provide a wire feeding frame that facilitates the disassembly of the wire feeding roller, thereby solving the problem mentioned in the background art that the existing wire feeding frames are not convenient for disassembling the wire feeding roller.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire feeding frame for easy disassembly of the wire feeding roller, comprising: a body and a lifting mechanism; a movable frame is slidably connected to the top of the body; a wire feeding roller body is provided on one side of the movable frame; a servo motor is installed on one side of the body; a bidirectional threaded rod is fixedly connected to the output end of the servo motor; the outer side of the bidirectional threaded rod is threadedly connected to the movable frame; a lifting mechanism is provided at the top of the body; the lifting mechanism includes a movable block threadedly connected to the outer side of the bidirectional threaded rod; a connecting rod is movably connected to the top of the movable block via a rotating shaft; a connecting plate a is movably connected to one end of the connecting rod via a rotating shaft; multiple sets of sliding rods are slidably connected inside the connecting plate a; a support plate is fixedly connected to the top of the sliding rods; and a limiting mechanism for restricting the movement of the sliding rods is provided inside the connecting plate a.

[0006] Preferably, a drive motor is installed on one side of the movable frame, and a connecting shaft is fixedly connected to the output end of the drive motor. The outer side of the connecting shaft is slidably connected to the wire feeding roller body.

[0007] Preferably, a protrusion is fixedly connected to one end of the connecting shaft, the outer side of the protrusion is slidably connected to the body of the feeding roller, a spring a is sleeved on the outer side of the slide rod, and the bottom of the spring a abuts against the connecting plate a.

[0008] Preferably, the top of the spring a abuts against the support plate, the outer side of the moving block is slidably connected to the machine body, and the top of the support plate is arc-shaped.

[0009] Preferably, the limiting mechanism includes a locking block that engages with the slide rod, and the slide rod has multiple sets of locking slots that match the locking block, and the multiple sets of locking slots are equidistantly distributed.

[0010] Preferably, a connecting rod is fixedly connected to one side of the locking block, and a spring b is sleeved on the outside of the connecting rod, with one end of the spring b abutting against the locking block.

[0011] Preferably, one end of the spring b abuts against the connecting plate a, and one end of the connecting rod is fixedly connected to the connecting plate b.

[0012] Compared with the prior art, the beneficial effect of the wire feeding frame for convenient disassembly of the wire feeding roller described in this utility model is as follows: When disassembling the wire feeding roller body, the servo motor is started to drive the bidirectional threaded rod to perform threaded transmission with the two sets of moving blocks and the moving frame. The moving frame will drive the connecting shaft and the protrusion to gradually disengage from the inside of the wire feeding roller body, while the two sets of moving blocks will move in opposite directions. When the moving blocks move, they will drive the connecting rod at the top to rotate, thereby driving the connecting plate a at the top to move upward, so that the support plate contacts the wire feeding roller body at the top. When the wire is wound on the outside of the wire feeding roller body, the diameter of the wire feeding roller body will increase. Therefore, when the support plate continues to move upward with the connecting plate a, it will squeeze the spring a at the bottom, thereby adapting to the diameter of the wire feeding roller body. In this way, the above operation can automatically support the wire feeding roller body when disassembling it, making it convenient to disassemble the wire feeding roller body.

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.

[0020] Please see Figures 1-5 The present invention provides a wire feeding frame for easy disassembly of the wire feeding roller, comprising: a body 1 and a lifting mechanism 6, a movable frame 2 slidably connected to the top of the body 1, and a wire feeding roller body 3 provided on one side of the movable frame 2.

[0021] A servo motor 4 is installed on one side of the body 1. A bidirectional threaded rod 5 is fixedly connected to the output end of the servo motor 4. The outer side of the bidirectional threaded rod 5 is threadedly connected to the moving frame 2. A lifting mechanism 6 is provided on the top of the body 1. The lifting mechanism 6 includes a moving block 601 that is threadedly connected to the outer side of the bidirectional threaded rod 5. A connecting rod 602 is movably connected to the top of the moving block 601 through a rotating shaft. A connecting plate a603 is movably connected to one end of the connecting rod 602 through a rotating shaft. Multiple sets of sliding rods 604 are slidably connected inside the connecting plate a603. A support plate 606 is fixedly connected to the top of the sliding rods 604. A limiting mechanism 7 that restricts the movement of the sliding rods 604 is provided inside the connecting plate a603.

[0022] A drive motor 8 is installed on one side of the movable frame 2. A connecting shaft 9 is fixedly connected to the output end of the drive motor 8. The outer side of the connecting shaft 9 is slidably connected to the wire feeding roller body 3. A protrusion 10 is fixedly connected to one end of the connecting shaft 9. The outer side of the protrusion 10 is slidably connected to the wire feeding roller body 3. A spring a605 is sleeved on the outer side of the slide rod 604. The bottom of the spring a605 abuts against the connecting plate a603. The top of the spring a605 abuts against the support plate 606. The outer side of the movable block 601 is slidably connected to the machine body 1. The top of the support plate 606 is arc-shaped. The connecting rod 602 forms a rotating structure with the movable block 601 through a rotating shaft. The connecting plate a605... The internal part of the 03 has a through hole that matches the slide rod 604. The slide rod 604 and the connecting plate a603 form a sliding structure. The limiting mechanism 7 includes a locking block 701 that engages with the slide rod 604. The internal part of the slide rod 604 has multiple sets of locking slots 704 that match the locking block 701, and the multiple sets of locking slots 704 are equidistantly distributed. A connecting rod 703 is fixedly connected to one side of the locking block 701. A spring b702 is sleeved on the outside of the connecting rod 703. One end of the spring b702 abuts against the locking block 701. One end of the spring b702 abuts against the connecting plate a603. One end of the connecting rod 703 is fixedly connected to the connecting plate b705.

[0023] In specific implementation, the wire feeding frame that facilitates the disassembly of the wire feeding roller, when disassembling the wire feeding roller body 3, drives the bidirectional threaded rod 5 to rotate by starting the servo motor 4. The bidirectional threaded rod 5 will be threadedly driven by the two sets of moving blocks 601 and the moving frame 2. The moving frame 2 will drive the connecting shaft 9 and the protrusion 10 to gradually disengage from the inside of the wire feeding roller body 3, while the two sets of moving blocks 601 will move in opposite directions. When the moving blocks 601 move, they will drive the connecting rod 602 at the top to rotate, thereby driving the connecting plate a603 at the top to move upward, so that the support plate 606 contacts the wire feeding roller body 3 at the top. When the wire is wound on the outside of the wire feeding roller body 3, the diameter of the wire feeding roller body 3 will increase. Therefore, when the support plate 606 continues to move upward with the connecting plate a603, it will squeeze the spring a605 at the bottom, thereby adapting to the diameter of the wire feeding roller body 3.

[0024] The slide bar 604 moves inside the connecting plate a603 and contacts the locking block 701 through the inclined surfaces of multiple sets of slots 704, causing the locking block 701 to move. When the connecting shaft 9 is completely disengaged from the inside of the pay-off roller body 3, the support plate 606 will completely support the pay-off roller body 3. If the weight of the pay-off roller body 3 is too heavy, the spring a605 will continue to contract until it can no longer contract. At this time, because the locking block 701 is engaged with the slots 704, the slide bar 604 and the support plate 606 cannot move upward, thus preventing the spring from moving upward. Spring a605 continuously contracts, causing the support plate 606 to move continuously, affecting the stability of the wire feeding roller body 3. This allows for the disassembly of the wire feeding roller. After the wire feeding roller body 3 is removed, the connecting plate b705 can be pulled to drive the two sets of connecting rods 703 to pull the locking block 701 to move and disengage from the sliding rod 604, so that spring a605 pushes the support plate 606 to reset. In this way, the above operation can automatically support the wire feeding roller body 3 during disassembly, making it convenient to disassemble the wire feeding roller body 3.

[0025] In summary: When using a wire feeding frame that facilitates the disassembly of the wire feeding roller, first start the servo motor 4 to drive the connecting shaft 9 at one end to rotate. The connecting shaft 9 will engage with the wire feeding roller body 3 through the protrusion 10 at the end, thereby driving the wire feeding roller body 3 to rotate and feed the wire.
