[0001] The present invention relates to the technical field of automatic wire pay-off for enameled round copper wire, and particularly to an automatic wire pay-off device for the production of enameled round copper wire. Background Art
[0002] As a key raw material for the manufacture of electrical equipment such as motors, transformers, and relays, enameled round copper wire is widely used in the fields of electric power industry, household appliances, etc. With the development of various industries, the market demand for enameled round copper wire continues to grow, and higher requirements are also put forward for production efficiency and product quality. In the wire pay-off part of the traditional enameling machine, operators need to spend a lot of energy and physical strength to replace the wire pay-off reels. Frequent wire replacement not only has a high labor intensity, but also the joints are prone to quality problems, which may further cause equipment operation failures. At the same time, the wire breakage problem also brings many troubles to the production of enameled round copper wire.

A wire pay-off device is correspondingly connected to the hollow part inside the housing. The wire pay-off device includes a support device and a sliding device. The support device will push the sliding device to move left and right, so as to achieve position adjustment. The bottom end of the sliding device is fixedly connected with a wire breakage device. As the sliding device moves, the wire breakage device can be accurately pushed to the designated position for cutting the enameled round copper wire.
[0005] As a preferred technical solution of the present invention, the support device includes two support rods. The protruding parts at the tops of the two support rods are fixedly connected with a first cylinder. The output shaft end of the first cylinder is fixedly connected with a connecting block, and the bottom of the connecting block is fixedly connected with a first sliding block.
[0006] As a preferred technical solution of the present invention, two first sliding rods are movably connected to the rear end of the first sliding block, and the rear ends of the two first sliding rods are fixedly connected to the front ends of the tops of the two support rods. Two second sliding rods are fixedly connected to the front end of the first sliding block. A long strip board is fixedly connected to the bottoms of the two second sliding rods. A second cylinder is fixedly connected to the center of the long strip board. A sliding device is fixedly connected to the output shaft end of the second cylinder.
[0007] As a preferred technical solution of the present invention, the sliding device includes two movable long blocks, and the rear ends of the two movable long blocks are movably connected to the outer surfaces of the two second sliding rods. A second sliding block is fixedly connected to the front ends of the two movable long blocks, and the inner side of the second sliding block is fixedly connected to the output shaft end of the second cylinder.

[0008] As a preferred technical solution of the present invention, annular blocks are fixedly connected to both sides of the bottom of the third sliding rod. A wire breaking device is fixedly connected to the bottom of the annular block. A moving block is movably connected to the outer surface of the third sliding rod. A connecting column is fixedly connected to the center of the front end of the moving block. A second wire pay-off reel is fixedly connected to the top end of the connecting column.
[0009] As a preferred technical solution of the present invention, the wire breaking device includes a double-output cylinder. The top of the double-output cylinder is fixedly connected to the groove at the bottom of the annular block. Semi-circular blocks are fixedly connected to both ends of the double-output cylinder. Polygonal plates are movably connected to the groove centers of the two semi-circular blocks. Cutting plates are fixedly connected to the bottoms of the two polygonal plates.
[0010] As a preferred technical solution of the present invention, arc-shaped connecting blocks are movably connected to the convex parts on the inner sides of the centers of the two polygonal plates.

[0011] Compared with the prior art, the beneficial effects of the present invention are: An automatic wire pay-off device for enameled copper round wire production. By connecting the output shaft end of the first cylinder to the top of the connecting block, when the first cylinder is started, the telescopic movement of its output shaft will push the movement of the connecting block. Since the bottom of the connecting block is fixedly connected to the top of the first sliding block, the movement of the connecting block will drive the first sliding block to reciprocally slide on the outer surfaces of the two first sliding rods.
[0012] An automatic wire pay-off device for the production of enameled copper round wire. After the first sliding block slides, it will drive the second sliding rod connected to its front end to move synchronously. The bottom of the second sliding rod is connected to the second cylinder. When the second sliding rod moves to the corresponding position, the second cylinder will start to push the sliding device connected to it to move further to one side. This two-stage linkage movement mode effectively increases the movement range of the sliding device and the wire-breaking device fixedly connected to its bottom. During the production of enameled copper round wire, it can better meet the need for quickly cutting the enameled copper round wire.
[0013] An automatic wire pay-off device for the production of enameled copper round wire. By movably connecting the movable long block to the outer surface of the second sliding rod, the movable long block can reciprocate on the outer surface of the second sliding rod. When the second cylinder starts and pushes the second sliding block to move to one side and reaches the appropriate position, the moving block will slide up and down on the outer surface of the third sliding rod. This sliding mode can adjust the height of the moving block. Since the moving block is fixedly connected to the second wire pay-off disc through the connecting column, the height of the second wire pay-off disc can be synchronously increased. During the wire pay-off process of the enameled copper round wire, by adjusting the height of the second wire pay-off disc, the enameled copper round wire can be in a better tension state, thereby effectively preventing the enameled copper round wire from breaking during the wire pay-off process.
[0014] An automatic wire pay-off device for the production of enameled copper round wire. By respectively arranging semi-circular blocks at both ends of the double-output cylinder, the double-output cylinder can push the semi-circular blocks to move to both sides. When the double-output cylinder starts, under the action of its thrust, the semi-circular blocks will drive the multi-sided plate movably connected to the central groove of the semi-circular blocks to shift towards the center. At this time, the cutting plates fixed to the bottoms of the two multi-sided plates will simultaneously move closer to the center, thereby performing a cutting operation on the enameled copper round wire to be cut. In addition, long rods are movably connected to the convex parts on the inner sides of the two multi-sided plates. When the multi-sided plates move towards the middle, the long rods will extend horizontally and be straightened. With the straightening action of the long rods, it can play a stabilizing and guiding role, prompting the two multi-sided plates on both sides to approach each other more stably and ensuring the cutting effect of the cutting plates on the enameled copper round wire.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Embodiment 1: Please refer to Figure 1 - Figure 2 , an automatic wire-releasing device for the production of enameled copper round wire, including an outer shell 1. One end of the top of the outer shell 1 is provided with a motor 2, and the bottom of the motor 2 is fixedly connected to one end of the top of the outer shell 1. The motor 2 is used to drive the first wire-releasing disc 3 to rotate. Two first wire-releasing discs 3 are provided at the front end of the outer shell 1, and the front end of the outer shell 1 is movably connected to the inner sides of the two first wire-releasing discs 3. The two first wire-releasing discs 3 are used to wind the enameled copper round wire and rotate and release the wire under the drive of the motor 2. Since the enameled copper round wire is wound on the first wire-releasing disc 3, the rotation of the first wire-releasing disc 3 realizes the wire-releasing operation of the enameled copper round wire, providing a continuous supply of enameled copper round wire for the subsequent production process. A wire-releasing device 4 is provided at the hollow part inside the outer shell 1, and the hollow part inside the outer shell 1 is correspondingly connected to the outer surface of the wire-releasing device 4. The wire-releasing device 4 includes a support device 41 and a sliding device 42. The support device 41 will push the sliding device 42 to move left and right, thereby realizing position adjustment. The bottom end of the sliding device 42 is fixedly connected to a wire-breaking device 43. As the sliding device 42 moves, the wire-breaking device 43 can be accurately pushed to the designated position for cutting the enameled copper round wire.
[0019] Embodiment 2: On the basis of Embodiment 1, as Figure 3 - 8As shown, the support device 41 includes two support rods 411. On the protruding parts at the tops of the two support rods 411, there is a first cylinder 412, and the protruding parts at the tops of the two support rods 411 are fixedly connected to the bottom end of the first cylinder 412. At the output shaft end of the first cylinder 412, there is a connecting block 413, and the output shaft end of the first cylinder 412 is fixedly connected to the top of the connecting block 413. By connecting the output shaft end of the first cylinder 412 to the top of the connecting block 413, when the first cylinder 412 is started, the telescopic movement of its output shaft will push the connecting block 413 to move. Since the bottom of the connecting block 413 is fixedly connected to the top of the first sliding block 414, the movement of the connecting block 413 will drive the first sliding block 414 to slide reciprocally on the outer surfaces of the two first sliding rods 415. At the bottom of the connecting block 413, there is a first sliding block 414, and the bottom of the connecting block 413 is fixedly connected to the top of the first sliding block 414.
[0020] At the rear end of the first sliding block 414, there are two first sliding rods 415, and the rear end of the first sliding block 414 is movably connected to the front ends of the two first sliding rods 415. The rear ends of the two first sliding rods 415 are both fixedly connected to the front ends at the tops of the two support rods 411. At the front end of the first sliding block 414, there are two second sliding rods 416, and the front end of the first sliding block 414 is fixedly connected to the rear ends of the two second sliding rods 416. At the bottoms of the two second sliding rods 416, there is a long strip plate 417, and the bottoms of the two second sliding rods 416 are fixedly connected to the inner sides of both ends of the long strip plate 417. At the center of the long strip plate 417, there is a second cylinder 418, and the center of the long strip plate 417 is fixedly connected to the outer surface of the bottom of the second cylinder 418. At the output shaft end of the second cylinder 418, there is a sliding device 42. After the first sliding block 414 slides, it will drive the second sliding rods 416 connected to its front end to move synchronously. The bottom of the second sliding rod 416 is connected to the second cylinder 418. When the second sliding rod 416 moves to the corresponding position, the second cylinder 418 will start to push the connected sliding device 42 to move further to one side. This two-stage linkage movement mode effectively increases the movement range of the sliding device 42 and the wire-breaking device 43 fixedly connected to its bottom. During the production process of enameled copper round wire, it can better meet the requirement of quickly cutting the enameled copper round wire, and can accurately adjust the wire-breaking device 43 to the best cutting starting position, thereby improving the cutting efficiency and cutting quality. And the output shaft end of the second cylinder 418 is fixedly connected to the rear end of the sliding device 42.
[0021] The sliding device 42 includes two movable long blocks 421. The rear ends of the two movable long blocks 421 are movably connected to the outer surfaces of the two second sliding rods 416. At the front ends of the two movable long blocks 421, there are second sliding blocks 422, and the front ends of the two movable long blocks 421 are fixedly connected to the rear ends of the second sliding blocks 422. The inner sides of the second sliding blocks 422 are fixedly connected to the output shaft ends of the second cylinders 418. At the center of the front end of the second sliding block 422, there is a third sliding rod 423, and the center of the front end of the second sliding block 422 is fixedly connected to the rear end of the third sliding rod 423.
[0022] On both sides of the bottom of the third sliding rod 423, there are annular blocks 427, and both sides of the bottom of the third sliding rod 423 are fixedly connected to the hollow parts at the bottom ends of the annular blocks 427. At the groove at the bottom of the annular block 427, there is a wire breaking device 43, and the groove at the bottom of the annular block 427 is fixedly connected to the top of the wire breaking device 43. On the outer surface of the third sliding rod 423, there is a moving block 424, and the outer surface of the third sliding rod 423 is movably connected to the groove of the moving block 424. At the center of the front end of the moving block 424, there is a connecting column 425, and the center of the front end of the moving block 424 is fixedly connected to the bottom of the connecting column 425. By movably connecting the movable long block 421 to the outer surface of the second sliding rod 416, the movable long block 421 can reciprocate on the outer surface of the second sliding rod 416. When the second cylinder 418 is started and the second sliding block 422 is pushed to move to one side and reaches a proper position, the moving block 424 will slide up and down on the outer surface of the third sliding rod 423. This sliding method can adjust the height of the moving block 424. Since the moving block 424 is fixedly connected to the second wire releasing disc 426 through the connecting column 425, the height of the second wire releasing disc 426 can be synchronously increased. During the wire releasing process of the enameled copper round wire, by adjusting the height of the second wire releasing disc 426, the enameled copper round wire can be in a better tension state, which helps to ensure that it has good mechanical strength, and further effectively prevents the enameled copper round wire from breaking during the wire releasing process. At the top end of the connecting column 425, there is a second wire releasing disc 426, and the top end of the connecting column 425 is fixedly connected to the rear end of the second wire releasing disc 426.
[0023] The wire breaking device 43 includes a double-output cylinder 431. The top of the double-output cylinder 431 is fixedly connected to the groove at the bottom of the annular block 427. At both ends of the double-output cylinder 431, there are semi-circular blocks 432, and both ends of the double-output cylinder 431 are fixedly connected to the bottoms of the semi-circular blocks 432. In the central grooves of the two semi-circular blocks 432, there are multi-sided plates 433, and the central grooves of the two semi-circular blocks 432 are movably connected to both sides of the tops of the multi-sided plates 433. At the bottoms of the two multi-sided plates 433, there are cutting plates 434, and the bottoms of the two multi-sided plates 433 are fixedly connected to the tops of the cutting plates 434.
[0024] Arc-shaped connecting blocks 435 are provided on the inner convex parts at the centers of the two multi-sided plates 433, and the inner convex parts at the centers of the two multi-sided plates 433 are movably connected to the bottoms of the arc-shaped connecting blocks 435. Rotating shafts 436 are provided at both ends of the two arc-shaped connecting blocks 435, and both ends of the two arc-shaped connecting blocks 435 are movably connected to both ends of the rotating shafts 436. By providing semi-circular blocks 432 at both ends of the double-acting cylinder 431 respectively, the double-acting cylinder 431 can push the semi-circular blocks 432 to move to both sides. When the double-acting cylinder 431 is started, under the action of its thrust, the semi-circular block 432 will drive the multi-sided plate 433 movably connected to the central groove of the semi-circular block 432 to shift towards the center. At this time, the cutting plates 434 fixed to the bottoms of the two multi-sided plates 433 will move towards the center simultaneously, so as to perform a cutting operation on the enameled copper round wire to be cut. In addition, a long rod 437 is movably connected to the inner convex parts of the two multi-sided plates 433. When the multi-sided plates 433 move towards the middle, the long rod 437 will extend horizontally and be straightened. With the straightening action of the long rod 437, it can play a role in stabilizing and guiding, prompting the multi-sided plates 433 on both sides to approach each other more accurately and stably, ensuring the cutting effect of the cutting plate 434 on the enameled copper round wire, and guaranteeing the reliability and stability of the cutting action. A long rod 437 is provided at the center of the two rotating shafts 436, and the centers of the two rotating shafts 436 are movably connected to both ends of the long rod 437.
[0025] The working principle of the present invention is as follows: After the equipment is started, the motor 2 at one end of the top of the housing 1 starts to work. The drive shaft of the motor 2 is connected to the first wire-releasing disc 3. When the motor 2 operates, it will drive the connected first wire-releasing disc 3 to rotate. Since the enameled copper round wire is wound around the first wire-releasing disc 3, the rotation of the first wire-releasing disc 3 realizes the wire-releasing operation of the enameled copper round wire, providing a continuous supply of enameled copper round wire for subsequent production processes; Principle of position adjustment of the wire-releasing device: The first cylinder 412 in the support device 41 plays a key role. When the first cylinder 412 is started, its output shaft will perform a telescopic action, pushing the moving of the connecting block 413 fixedly connected thereto. Since the bottom of the connecting block 413 is fixedly connected to the top of the first sliding block 414, the movement of the connecting block 413 will drive the first sliding block 414. The rear end of the first sliding block 414 is movably connected to the two first sliding rods 415, and the rear ends of the two first sliding rods 415 are both fixed to the front ends of the tops of the two support rods 411. Therefore, the first sliding block 414 will perform a reciprocating sliding on the outer surfaces of the two first sliding rods 415; Linkage of the sliding device: When the first sliding block 414 slides, it will drive the second sliding rod 416 connected to its front end to move synchronously. The bottom of the second sliding rod 416 is connected to a long strip 417, and a second cylinder 418 is fixed at the center of the long strip 417. After the second sliding rod 416 moves to the corresponding position, the second cylinder 418 will be activated, and its output shaft will push the connected sliding device 42 to move further to one side. This two-stage linkage movement mode, that is, the first cylinder 412 pushes the first sliding block 414 to move, which in turn drives the second sliding rod 416 to move, and then the second cylinder 418 pushes the sliding device 42, effectively increases the movement range of the sliding device 42 and the wire-breaking device 43 fixedly connected to its bottom, and can accurately adjust the wire-breaking device 43 to the optimal cutting starting position; Principle of height adjustment of the second wire pay-off reel: The movable long block 421 is movably connected to the outer surface of the second sliding rod 416, so that the movable long block 421 can reciprocate on the outer surface of the second sliding rod 416. When the second cylinder 418 is activated to push the second sliding block 422 to move to one side and reach the appropriate position, the moving block 424 will slide up and down on the outer surface of the third sliding rod 423. Since the front end of the moving block 424 is fixedly connected to the second wire pay-off reel 426 through a connecting column 425, the up and down sliding of the moving block 424 can adjust the height of the second wire pay-off reel 426. During the pay-off process of the enameled copper round wire, by adjusting the height of the second wire pay-off reel 426, the enameled copper round wire can be in a better tension state, which helps to ensure its good mechanical strength and effectively prevent the enameled copper round wire from breaking during the pay-off process; Principle of wire breaking and cutting: When it is necessary to cut the enameled copper round wire, the wire-breaking device 43 starts to work. Both ends of the double-output cylinder 431 are fixedly connected to semi-circular blocks 432. After the double-output cylinder 431 is activated, it pushes the semi-circular blocks 432 to move to both sides. The center groove of the semi-circular block 432 is movably connected to a multi-sided plate 433. When the semi-circular block 432 moves, it will drive the multi-sided plate 433 to shift towards the center. Since the bottoms of the two multi-sided plates 433 are fixedly connected to the cutting plate 434, when the multi-sided plates 433 shift towards the center, the cutting plates 434 will simultaneously move closer to the center, so as to cut the enameled copper round wire to be cut. At the same time, the convex parts on the inner sides of the two multi-sided plates 433 are movably connected to a long rod 437 through an arc-shaped connecting block 435 and a rotating shaft 436. When the multi-sided plates 433 move towards the middle, the long rod 437 will stretch horizontally and be straightened. The straightened long rod 437 plays a role in stabilizing and guiding, prompting the multi-sided plates 433 on both sides to approach each other more accurately and stably, ensuring the cutting effect of the cutting plate 434 on the enameled copper round wire, and guaranteeing the reliability and stability of the cutting action.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
