Description

Technical Field

[0001] The invention relates to the technical field of winding machines, and in particular to a winding machine for winding a silk thread. Background Art

[0002] As a widely used equipment in industrial production, the winding machine is used to wind wire materials (such as silk threads, cables, etc.) on the core shaft according to certain rules to form a wire coil for easy storage, transportation and use. Its working principle can be briefly described as follows: the drive device drives the relatively fixed axis of the reel to rotate, transfers the material to the surface of the reel, and then controls the tension and position of the material through the tension system and positioning system, and finally cuts the wound material to achieve the purpose of winding.

[0003] A technical solution for aluminum alloy cable manufacturing equipment is disclosed in a Chinese patent with publication number CN117902125A. In this technical solution, the cable is wound up by rotating the winding roller clockwise, and then rotating it counterclockwise. On the one hand, the cable is cut, and on the other hand, the winding tape is attached to the winding roller. Then, the winding roller is rotated clockwise again to bundle the cable, and finally, the winding roller is rotated counterclockwise again to release the restriction on the rack through the limit reset mechanism, thereby driving the rack, winding tape, and compression and cutting mechanism to reset.

[0004] During the operation of the winding machine, it is necessary to frequently replace the reel. However, the patent does not improve the reel replacement, and the existing reel fixing and disassembly process is too cumbersome, usually requiring staff to manually operate screws or clamping devices to fix the reel. This operation method is not only time-consuming, but also further reduces work efficiency; in addition, the surface of the reel is smooth, making it difficult to firmly fix the silk thread on it.

[0005] In addition, this patent requires that the cable can only be cut by rotating the winding roller counterclockwise after the cable is rolled up by rotating the winding roller clockwise. The cable cannot be cut during the winding process of the winding roller. The process is cumbersome. The cutting mechanism and the winding roller are designed to be separated and are far apart. After the cutting mechanism cuts the cable, there is still a part of the wire that has not been rolled up. The remaining part can only be rolled up when the winding roller is rotated clockwise to bundle the cable.

[0006] However, the lack of a guide structure between the cutting mechanism and the winding roller causes the remaining cable to easily swing, resulting in uneven winding or collision with other components. If the cable end is not handled properly, it will lead to poor product appearance or reduced performance. Summary of the invention

[0007] The purpose of the present invention is to facilitate the fixing and installation of the wire and the winding drum, and to automatically cut and fix the wire after winding.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a winding machine for winding a silk thread, comprising a support column and a motor mounted on a workbench, the support column being rotatably connected to a driving column, a first ratchet wheel being arranged in the driving column, the first ratchet wheel being engaged with a first pawl on a driving rod, one end of the driving rod passing through the driving column and being connected to the motor through a belt, and the other end being connected to a reciprocating protrusion structure in the driving column; The outer ring of the driving column is sleeved with a winding drum, which includes a fixed drum and a rotating drum clamped with the driving column, the rotating drum is rotatably connected with a connecting ring, a plurality of first springs fixed with the fixed drum are fixed on the connecting ring, and a locking structure is provided on the rotating drum; A positioning device is installed on the workbench, the motor and the positioning device are driven by a belt, a linear reciprocating structure driven by a driving rod is installed on the support column, and a cutting blade and a pressing plate are installed on the top of the linear reciprocating structure.

[0009] As a further description of the above technical solution: the reciprocating protrusion structure includes a rectangular plate, a sliding plate is slidably connected to the rectangular plate, the top of the sliding plate passes through the driving column, a push block is fixed to the top of the sliding plate, and a driving disk fixed to the driving rod is rotatably connected to the rectangular plate, and the driving disk is engaged with the inner ring of the sliding plate.

[0010] As a further description of the above technical solution: the locking structure includes an L-shaped groove arranged on the rotating cylinder, a sliding column fixed to the fixed cylinder is slidably connected in the L-shaped groove, the L-shaped groove is connected to a rectangular groove, and a protrusion engaged with the rotating cylinder is fixed on the driving column.

[0011] As a further description of the above technical solution: a second spring is fixed to the inner wall of the rectangular groove, a limit block slidably connected to the rectangular groove is fixed to the second spring, and a paddle is fixed to the top of the limit block.

[0012] As a further description of the above technical solution: the positioning device includes two support plates, between which a reciprocating screw is rotatably connected and a sliding column is fixedly connected, on which an adjustment block is fixed and a guide is slidably connected, and at the bottom of the guide a transmission rod engaged with the reciprocating screw is rotatably connected, and the reciprocating screw and the motor are driven by a belt.

[0013] As a further description of the above technical solution: the linear reciprocating structure includes a slide fixed on a support column, a slide rod sliding on the slide, the slide rod is fixed with a height-adjustable connector by bolts, a support frame is fixed on the workbench, a drive rod passes through the inner cavity of the transmission column and is rotatably connected to its inner wall, and a lock for locking the drive column and the transmission column is fixed on the support column.

[0014] As a further description of the above technical solution: the connecting piece is fixed to the cutting blade and the clamping plate, the transmission column passes through the support frame and is rotatably connected thereto, the support column is connected to a rotating rod, and a first protruding rod is fixed to the sliding rod.

[0015] As a further description of the above technical solution: the transmission column is fixed with a second protruding rod, the first protruding rod and the second protruding rod both pass through the groove on the surface of the rotating rod, and a second ratchet is arranged inside the transmission column, and the second ratchet is engaged with a second pawl fixed on the driving rod.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The motor drives the winding drum and the positioning device at the same time, so that the winding drum rotates clockwise to reel in the silk thread. At the same time, the positioning device can accurately control the position of the silk thread during the reeling process. The single-motor drive method simplifies the transmission system. The movement of the winding drum and the positioning device is synchronized, which ensures the uniform winding of the silk thread, thereby reducing production costs and improving production efficiency.

[0017] 2. When the motor rotates clockwise, the linear reciprocating structure converts the rotational motion of the drive rod into linear reciprocating motion, thereby prompting the cutting blade and the pressing plate to move up and down. During the descent of the cutting blade, the wire is cut off. At this time, the linear reciprocating structure stops moving, and the pressing plate fixes the cut wire. Through linear motion, the cutting blade and the pressing plate are directly driven, avoiding complex mechanical transmission and thus improving work efficiency.

[0018] 3. A linear reciprocating structure, a cutting blade and a pressing plate are arranged near the winding drum. The cutting blade can cut the wire, and the remaining wire is short and does not need to be rewound, thus avoiding unnecessary winding process and improving production efficiency. The end of the wire after cutting is pressed and fixed to prevent loosening, thereby improving product quality.

[0019] 4. One end of the wire is placed between the fixed cylinder and the rotating cylinder. When the motor rotates counterclockwise, the ratchet and the pawl will not drive the winding cylinder, the cutting device and the linear reciprocating structure to move. The driving rod drives the reciprocating protrusion structure to protrude from the driving column, and squeezes the fixed cylinder toward the rotating cylinder. While fixing the winding cylinder, the wire is fixed before winding. When the motor rotates clockwise, the locking structure will automatically fix the fixed cylinder and the rotating cylinder, and the locking structure can be released manually.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 11 The present invention provides a winding machine for winding silk thread, comprising a support column 11 and a motor 12 installed on a workbench 10, wherein a driving column 20 is rotatably connected to the support column 11, and the driving column 20 is a hollow cylinder. A first ratchet 201 is arranged inside the driving column 20, and the first ratchet 201 is engaged with a first pawl 211 on a driving rod 21; when the driving rod 21 rotates clockwise, the first pawl 211 drives the first ratchet 201 to rotate the driving column 20, and when the driving rod 21 rotates counterclockwise, the first pawl 211 cancels the transmission to the first ratchet 201.

[0024] One end of the driving rod 21 passes through the driving column 20 and is connected to the motor 12 through a belt. The motor 12 can make the driving rod 21 rotate clockwise or counterclockwise. The other end of the driving rod 21 is connected to the reciprocating protrusion structure 30 in the driving column 20; when the driving rod 21 rotates clockwise, the driving column 20 and the reciprocating protrusion structure 30 will rotate clockwise synchronously, and the driving rod 21 cannot drive the reciprocating protrusion structure 30 to move. When the driving rod 21 rotates counterclockwise, the driving rod 21 will not drive the driving column 20 to rotate counterclockwise, but will cause the reciprocating protrusion structure 30 to move, thereby generating a bulge on the outer ring of the driving column 20.

[0025] The outer ring of the driving column 20 is provided with a winding drum 60, and the winding drum 60 includes a fixed drum 61 and a rotating drum 62 clamped with the driving column 20. Therefore, when the driving column 20 rotates clockwise, the rotating drum 62 will rotate clockwise due to the clamping relationship between them.

[0026] A connecting ring 621 is connected to the rotating cylinder 62, and a plurality of first springs 611 are fixed on the connecting ring 621. A locking structure 63 is provided on the rotating cylinder 62. When the silk thread needs to be fixed, the silk thread is placed in the gap between the fixed cylinder 61 and the rotating cylinder 62. Then, through the movement of the reciprocating protrusion structure 30, a bulge is generated on the outer ring of the driving column 20, so that the fixed cylinder 61 is squeezed toward the rotating cylinder 62. The fixed cylinder 61 and the rotating cylinder 62 cooperate with each other to clamp the silk thread, which is convenient for fixing the silk thread and improves the production efficiency. When the winding drum 60 rotates clockwise, the locking structure 63 will automatically lock the fixed cylinder 61 and the rotating cylinder 62 without manual operation, thereby improving the production efficiency. Even if the winding drum 60 is removed from the driving column 20, the locking structure 63 will not be unlocked, thereby ensuring the stability of the locking.

[0027] A positioning device 70 is installed on the workbench 10, and the motor 12 is connected to the positioning device 70 through a belt drive. The single motor 12 drive method simplifies the transmission system. The movement of the winding drum 60 and the positioning device 70 is synchronized, ensuring the uniform winding of the silk thread, thereby reducing production costs and improving production efficiency.

[0028] At the same time, a linear reciprocating structure 80 is also installed on the support column 11. The linear reciprocating structure 80 is driven by the driving rod 21 and can realize linear reciprocating motion. A cutting blade 40 and a pressing plate 50 are installed on the top of the linear reciprocating structure 80.

[0029] When the driving rod 21 rotates clockwise, the linear reciprocating structure 80 will drive the cutting blade 40 and the clamping plate 50 to move back and forth. As the wire is continuously wound on the winding drum 60, the thickness of the wire on the winding drum 60 will continue to increase, and the wire will contact the cutting blade 40. The cutting blade 40 will cut the wire. At this time, the movement of the motor 12 will stop, and the clamping plate 50 will press on the wire on the outer circle of the winding drum 60.

[0030] The cutting blade 40 and the pressing plate 50 are arranged near the winding drum 60. The remaining wire after being cut by the cutting blade 40 is short and does not need to be rewound, thus avoiding unnecessary winding process and improving production efficiency. The end of the wire after cutting is pressed and fixed to prevent loosening, thereby improving product quality.

[0031] Furthermore, the reciprocating protrusion structure 30 includes a rectangular plate 31, on which a sliding plate 32 is slidably connected, the top of the sliding plate 32 passes through the driving column 20, a push block 33 is fixed to the top of the sliding plate 32, and a driving disk 34 fixed to the driving rod 21 is rotatably connected to the rectangular plate 31, and the driving disk 34 is engaged with the inner ring of the sliding plate 32.

[0032] During operation, the driving rod 21 rotates counterclockwise, thereby driving the driving disk 34 to rotate counterclockwise. The movement of the driving disk 34 further drives the sliding plate 32 to slide back and forth on the rectangular plate 31. Subsequently, the sliding plate 32 drives the push block 33 to intermittently pass through the driving column 20. The push block 33 is close to one side of the fixed cylinder 61, and its inclined surface matches the inclined surface of the inner circle of the fixed cylinder 61.

[0033] When the push block 33 passes through the driving column 20, the fixed cylinder 61 and the rotating cylinder 62 can be quickly fixed to the driving column 20, and the push block 33 allows the fixed cylinder 61 to move toward the rotating cylinder 62, and at the same time realizes the fixation of the silk thread before winding, without manual operation, shortening the production cycle and improving the production efficiency of the winding machine.

[0034] Furthermore, the locking structure 63 includes an L-shaped groove 631 arranged on the rotating cylinder 62, in which a sliding column 632 fixed to the fixed cylinder 61 is slidably connected, the L-shaped groove 631 is connected to a rectangular groove 633, a second spring 634 is fixed to the inner wall of the rectangular groove 633, the second spring 634 is fixed to a limit block 635 slidably connected to the rectangular groove 633, and a paddle 636 is fixed to the top of the limit block 635; a protrusion 202 engaged with the rotating cylinder 62 is fixed on the driving column 20, and when the driving column 20 rotates clockwise, the rotating cylinder 62 can be driven to rotate clockwise through the protrusion 202.

[0035] During operation, when the fixed cylinder 61 moves toward the rotating cylinder 62, the sliding column 632 will move in the L-shaped groove 631 from the side close to the first spring 611 to the side away from the first spring 611. After contacting the inner wall of the L-shaped groove 631, the sliding column 632 stops moving; and when the driving column 20 rotates clockwise, the rotating cylinder 62 will also rotate clockwise, causing the limit block 635 to move toward the sliding column 632. Under the squeezing action of the sliding column 632, the limit block 635 will move into the rectangular groove 633. When the sliding column 632 moves to the other side of the inclined surface of the limit block 635, the limit block 635 will be reset under the drive of the second spring 634, thereby fixing the sliding column 632 at this position.

[0036] When the limit block 635 fixes the slide post 632 in this position, the fixed cylinder 61 and the rotating cylinder 62 will keep the wire clamped, and the locking structure 63 will not be unlocked even if the winding drum 60 is removed from the driving column 20; after the wound wire is removed from the fixed cylinder 61 and the rotating cylinder 62, the limit block 635 can release the fixation of the slide post 632 by toggling the paddle 636, thereby allowing the fixed cylinder 61 and the rotating cylinder 62 to release the clamping of one end of the wire.

[0037] During the wire winding process, the locking structure 63 can automatically complete the locking without manual intervention, thereby improving work efficiency; in addition, the operation of the locking structure 63 does not rely on additional power drive, effectively reducing energy consumption; the unlocking operation only requires moving the paddle 636, which is simple and convenient to operate.

[0038] Furthermore, the positioning device 70 includes two support plates 71, between which a reciprocating screw 72 is rotatably connected and a sliding column 73 is fixedly connected, and the sliding column 73 is respectively fixed with an adjustment block 74 and a guide 75 is slidably connected, and the adjustment block 74 is detachably fixed to the sliding column 73 by bolts, and the moving range of the guide 75 can be limited by the adjustment block 74. The wire passes through the guide 75, and the wire can be evenly wound onto the outer ring of the winding drum 60 through the guide 75. The bottom of the guide 75 is rotatably connected to a transmission rod 76 meshing with the reciprocating screw 72, and the reciprocating screw 72 and the motor 12 are driven by a belt.

[0039] During operation, the reciprocating screw rod 72 rotates clockwise under the drive of the motor 12, and then drives the guide 75 to slide back and forth on the sliding column 73 through the transmission rod 76. Through the reciprocating motion of the guide 75, the wire can be evenly wound on the winding drum 60, thereby improving the winding quality.

[0040] Furthermore, the linear reciprocating structure 80 includes a slide table 81 fixed on the support column 11, and a slide rod 82 slides on the slide table 81. A connecting piece 83 with adjustable height is fixed to the slide rod 82 by bolts. The connecting piece 83 is fixed to the cutting blade 40 and the clamping plate 50. By changing the position of the connecting piece 83, the height of the cutting blade 40 and the clamping plate 50 can be adjusted, and the wire can be cut when the wire is wound to different thicknesses, thereby improving the practicality of the device. A support frame 84 is fixed on the workbench 10, and the drive rod 21 passes through the inner cavity of the transmission column 85 and is rotatably connected to the inner wall. A lock 13 for locking the drive column 20 and the transmission column 85 is fixed on the support column 11.

[0041] The locker 13 is composed of an electric telescopic rod and a pressure plate. When the driving rod 21 rotates counterclockwise, the electric telescopic rod drives the pressure plate to move toward the driving column 20 and the transmission column 85, and the pressure plate squeezes the driving column 20 and the transmission column 85 so that they will not rotate.

[0042] The transmission column 85 passes through the support frame 84 and is rotatably connected thereto. A rotating rod 86 is rotatably connected to the support column 11. A first protruding rod 821 is fixed to the sliding rod 82. A second protruding rod 851 is fixed to the transmission column 85. Both the first protruding rod 821 and the second protruding rod 851 pass through grooves provided on the surface of the rotating rod 86. A second ratchet 852 is provided in the transmission column 85. The second ratchet 852 engages with the second pawl 212 on the driving rod 21.

[0043] During operation, when the driving rod 21 rotates counterclockwise, under the action of the lock 13, the transmission column 85 will not rotate counterclockwise, and the cutting blade 40 and the clamping plate 50 will not move; when the driving rod 21 rotates clockwise, through the transmission of the second pawl 212, the second ratchet 852 rotates clockwise, and the transmission column 85 also rotates clockwise. The transmission column 85 drives the rotating rod 86 to perform a fan-shaped reciprocating motion through the second protruding rod 851, and the rotating rod 86 drives the sliding rod 82 to perform a linear reciprocating motion through the first protruding rod 821, thereby driving the cutting blade 40 and the clamping plate 50 to move up and down.

[0044] During use, the winding drum 60 is installed on the driving column 20, and the end of the wire is placed between the fixed cylinder 61 and the rotating cylinder 62. Subsequently, the locking device 13 is used to lock the driving column 20 and the transmission column 85. Then, driven by the motor 12, the driving rod 21 rotates counterclockwise in the driving column 20 and the transmission column 85. Through the sliding plate 32 and the driving disk 34, the driving rod 21 allows the push block 33 to pass through the driving column 20. When the push block 33 passes through the driving column 20, the fixed cylinder 61 and the rotating cylinder 62 can be quickly fixed to the driving column 20, and the push block 33 causes the fixed cylinder 61 to move toward the rotating cylinder 62, thereby achieving fixation of the wire before winding.

[0045] The locker 13 releases the lock on the drive column 20 and the transmission column 85. The drive rod 21 drives the drive column 20 and the transmission column 85 to rotate synchronously clockwise through the ratchet and the pawl. The drive column 20 drives the winding drum 60 to rotate clockwise to rewind the wire. During the rotation, the locking structure 63 automatically locks the fixed cylinder 61 and the rotating cylinder 62. The transmission column 85 drives the sliding rod 82 to perform linear reciprocating motion through the rotating rod 86, thereby driving the cutting blade 40 and the clamping plate 50 to move up and down. The cutting blade 40 can cut the wire. The remaining wire is short and does not need to be rewound, which avoids unnecessary winding process and improves production efficiency. The end of the wire after cutting is pressed and fixed to prevent loosening, thereby improving product quality.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
