Description

Technical Field

[0001] This invention relates to the field of underwear fabric production technology, specifically to a winding device for underwear fabric production. Background Technology

[0002] Underwear fabrics are mainly divided into two categories: natural fibers and synthetic fibers. Different materials have their own characteristics in terms of comfort, breathability and functionality.

[0003] After the production of lingerie fabrics is completed, they need to be rolled up for transportation. Currently, a rolling device is generally used to roll up the lingerie fabrics. However, the rolling devices currently used generally roll up the lingerie fabrics by pulling them directly. When rolling up some elastic lingerie fabrics, the lingerie fabrics will be in a taut state after rolling. This state will cause the elastic lingerie fabrics to become soft, resulting in a decrease in their elasticity and affecting the production quality of elastic lingerie. Summary of the Invention

[0004] The purpose of this invention is to provide a winding device for producing underwear fabrics, so as to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] This invention relates to a winding device for producing underwear fabric, comprising a base plate, a support plate fixedly connected to the top of the base plate, a motor fixedly connected to the surface of the support plate, a winding rod fixedly connected to the output end of the motor, a fixing plate fixedly connected to the top of the base plate, a limit frame fixedly connected to the top of the fixing plate, a feeding frame fixedly connected to the end of the limit frame away from the fixing plate, and a discharging frame fixedly connected to the end of the feeding frame; a pushing component is provided inside the feeding frame, a pulling component is provided at the end of the feeding frame, and a pressing component is provided on the surface of the support plate;

[0007] The pushing component includes a gearbox, the surface of which is fixedly connected to the surface of the feeding frame. A power unit is fixedly connected to the end of the gearbox away from the feeding frame. A circular hole rod is fixedly connected to the inner wall of the limiting frame. A rotating rod is rotatably connected to the inner wall of the circular hole rod. A central rod is fixedly connected to the surface of the rotating rod. A spring rod is fixedly connected to the surface of the central rod. A pushing plate is fixedly connected to the end of the spring rod away from the central rod. A gear is fixedly connected to the surface of the rotating rod.

[0008] Furthermore, the discharge rack is located at the end of the feed rack near the winding rod, and the end of the winding rod away from the motor passes through the support plate and extends to the outer end of the support plate. The number of the round hole rods is set to four, and the four round hole rods are set to two groups, with two rods in each group.

[0009] Furthermore, the two sets of circular hole rods are symmetrically arranged vertically around the feed rack. The end of the rotating rod passes through the circular hole rod and extends to the outer end of the circular hole rod. The end of the rotating rod near the gearbox passes through the gearbox and is fixedly connected to the output end of the power device. The gear is located inside the gearbox.

[0010] Furthermore, there are two gears, with their ends meshing together. The central rod is located inside the limiting frame. There are eight pusher plates, arranged in two groups of four, with each group containing four pusher plates. The four pusher plates are arranged in a circle around the central rod.

[0011] Furthermore, the material pulling component includes a turntable, the surface of which is fixedly connected to the end of a rotating rod. There are two turntables, and a pulling plate is rotatably connected to one end of each turntable that is close to the other. A sliding plate is fixedly connected to the surface of the feeding frame, and a movable frame is slidably connected to the surface of the sliding plate. The end of the pulling plate away from the turntable is sleeved on the surface of the movable frame. A mounting frame is fixedly connected to the top of the movable frame, and a positioning plate is fixedly connected to the surface of the mounting frame. A through-hole frame is fixedly connected to the bottom of the positioning plate, and an opening and closing plate is hinged to the top of the inner wall of the through-hole frame.

[0012] Furthermore, there are two slide plates, which are symmetrically arranged around the feed rack. The ends of the slide plates extend to the outer end of the feed rack, and the through-hole rack is located at the end of the feed rack away from the discharge rack.

[0013] Furthermore, the end of the pull plate near the turntable is eccentrically positioned, the bottom of the opening and closing plate extends to the bottom outer end of the through-hole frame, and the turntable is located at the end of the rotating rod away from the gearbox.

[0014] Furthermore, the extrusion component includes a limiting plate, an arc plate fixedly connected to the end of the limiting plate, a connecting plate fixedly connected to the surface of the limiting plate, a bidirectional electric actuator fixedly connected to the surface of the connecting plate, the surface of the bidirectional electric actuator fixedly connected to the surface of the support plate, a right-angle plate fixedly connected to the surface of the support plate, an electric rod fixedly connected to the surface of the right-angle plate, a circular hole ring fixedly connected to the telescopic end of the electric rod, and a sliding groove provided at the end of the support plate away from the motor.

[0015] Furthermore, there are two slides, which are symmetrically arranged with the winding rod as the center. The end of the limiting plate away from the arc plate contacts the inner wall of the slide, and the winding rod is located inside the circular hole ring.

[0016] Furthermore, the surface of the circular hole ring is in contact with the surface of the support plate, and there are two connecting plates, which are symmetrically arranged around the bidirectional electric actuator.

[0017] The present invention has the following beneficial effects:

[0018] This invention involves feeding the finished lingerie fabric through a feeding frame and winding it onto the surface of a take-up rod. A motor is then started to rotate the take-up rod, winding the lingerie fabric. After the fabric is placed inside the feeding frame, a power unit is activated to rotate a rotating rod inside a circular hole rod. As the rotating rod rotates, it drives a pusher plate to rotate inside the feeding frame via a connection between a central rod and a spring rod. Two central rods are located inside the feeding frame, and their internal rotating rods are connected by gears. The two rotating rods rotate in opposite directions. The two central rods cooperate to push the fabric through the pusher plate... The lingerie fabric is fed to one end of the feed rack, causing a small amount of fabric to accumulate near the feed rack. When the winding rod winds the fabric, it easily pulls it out and winds it up, avoiding the need to pull the fabric during winding, which would cause the fabric to be in an elastically expanded state after winding, affecting the production quality of the lingerie. At the same time, a gap is provided between the inner wall of the feed rack and the lingerie fabric to prevent excessive friction between the fabric and the inner wall of the feed rack, which would result in excessive tension during winding. The feed rack can also smooth out the lingerie fabric.

[0019] When the rotating rod of this invention rotates, it drives the turntable to rotate. Because the pull plate and the turntable are eccentrically set, the turntable pushes the moving frame to slide on the surface of the slide plate through the pull plate when it rotates. When the slide plate moves, it drives the through-hole frame to move through the connection between the mounting frame and the positioning plate. When the through-hole frame moves towards the feeding frame, the opening and closing plate in the through-hole frame will be stuck on the surface of the through-hole frame due to the friction with the underwear fabric. At this time, the through-hole frame and the opening and closing plate cooperate to pull the underwear fabric and convey the underwear fabric into the interior of the feeding frame, improving the conveying efficiency of the push plate on the underwear fabric and avoiding insufficient friction between the push plate and the underwear fabric, which affects the transmission effect. When the through-hole frame moves away from the end of the feeding frame, the opening and closing plate will be in a slightly open state so that the through-hole frame can slide on the surface of the underwear fabric. At this time, the through-hole frame moves back and forth at the end of the feeding frame with the rotation of the turntable, and conveys the underwear fabric into the interior of the feeding frame to complete the conveying operation during the movement. This reduces the pulling force of the winding rod on the underwear fabric when winding, and avoids the underwear fabric being in a state of elastic expansion for a long time, which affects its quality.

[0020] After the winding rod of this invention completes the winding of the underwear fabric, the bidirectional electric actuator is activated to push the two connecting plates to move closer to each other. When the connecting plates move, they push the limiting plate to slide inside the slide groove. The slide groove limits the limiting plate and improves the stability of the arc plate during operation. When the arc plates move closer to each other, they will squeeze the underwear fabric. At this time, the storage bag can be put on the surface of the arc plate. The electric rod is activated to start the operation. The electric rod pushes the circular ring to move, and during the movement, it pushes the wound underwear fabric to separate from the surface of the winding rod. Because the storage bag is put on the surface of the arc plate, the underwear fabric separated from the winding rod will be directly pushed into the interior of the storage bag for storage, improving the convenience of packaging and transporting underwear fabric.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] Please see Figures 1-8 As shown, the present invention is a winding device for producing underwear fabric, including a base plate 1, a support plate 3 fixedly connected to the top of the base plate 1, a motor 4 fixedly connected to the surface of the support plate 3, a winding rod 2 fixedly connected to the output end of the motor 4, a fixing plate 5 fixedly connected to the top of the base plate 1, a limit frame 8 fixedly connected to the top of the fixing plate 5, a feeding frame 7 fixedly connected to the end of the limit frame 8 away from the fixing plate 5, and a discharging frame 6 fixedly connected to the end of the feeding frame 7; a pushing component 9 is provided inside the feeding frame 7, a pulling component 10 is provided at the end of the feeding frame 7, and a pressing component 11 is provided on the surface of the support plate 3;

[0035] The pushing component 9 includes a gearbox 20, the surface of which is fixedly connected to the surface of the feed rack 7. A power unit 21 is fixedly connected to the end of the gearbox 20 away from the feed rack 7. A circular hole rod 27 is fixedly connected to the inner wall of the limiting frame 8. A rotating rod 26 is rotatably connected to the inner wall of the circular hole rod 27. A center rod 24 is fixedly connected to the surface of the rotating rod 26. A spring rod 23 is fixedly connected to the surface of the center rod 24. A pushing plate 25 is fixedly connected to the end of the spring rod 23 away from the center rod 24. A gear 22 is fixedly connected to the surface of the rotating rod 26. The pushed material will then push the finished product... The underwear fabric passes through the feed rack 7 and is wrapped around the surface of the take-up rod 2. At this time, the motor 4 is started to drive the take-up rod 2 to rotate and take up the underwear fabric. After the underwear fabric is placed inside the feed rack 7, the power device 21 is started to drive the rotating rod 26 to rotate inside the round hole rod 27. When the rotating rod 26 rotates, it drives the pusher plate 25 to rotate inside the feed rack 7 through the connection between the center rod 24 and the elastic rod 23. There are two center rods 24 inside the feed rack 7, and the rotating rods 26 inside the two center rods 24 are connected by gears 22.

[0036] The discharge rack 6 is located at the end of the feed rack 7 near the take-up rod 2. The end of the take-up rod 2 away from the motor 4 passes through the support plate 3 and extends to the outer end of the support plate 3. There are four round hole rods 27, which are set in two groups, and each group has two rods. The two rotating rods 26 rotate in opposite directions. At this time, the two center rods 24 cooperate with each other to convey the underwear fabric to one end of the discharge rack 6 through the push plate 25, so that the underwear fabric will be piled up in a small amount at the end of the feed rack 7 near the discharge rack 6. At this time, when the take-up rod 2 takes up the underwear fabric, it will easily pull it out and roll it up, avoiding the need to pull the underwear fabric when taking up the underwear fabric.

[0037] Two sets of circular hole rods 27 are symmetrically arranged vertically around the feed rack 7. The end of the rotating rod 26 passes through the circular hole rod 27 and extends to the outer end of the circular hole rod 27. The end of the rotating rod 26 near the gearbox 20 passes through the gearbox 20 and is fixedly connected to the output end of the power unit 21. The gear 22 is located inside the gearbox 20.

[0038] There are two gears 22, and the two gears 22 mesh with each other at their close ends. The center rod 24 is located inside the limit frame 8. There are eight pusher plates 25, which are set in two groups, and each group has four pusher plates 25 arranged around the center rod 24.

[0039] The material pulling component 10 includes a turntable 33, the surface of which is fixedly connected to the end of the rotating rod 26. Two turntables 33 are provided, and a pulling plate 36 is rotatably connected to one end of each turntable 33 that is close to the other. A sliding plate 30 is fixedly connected to the surface of the feeding frame 7, and a movable frame 31 is slidably connected to the surface of the sliding plate 30. The end of the pulling plate 36 away from the turntable 33 is sleeved on the surface of the movable frame 31. A mounting frame 32 is fixedly connected to the top of the movable frame 31, and a positioning plate 37 is fixedly connected to the surface of the mounting frame 32. A through-hole frame 34 is fixedly connected to the bottom of the positioning plate 37. The inner wall of the through-hole frame 34... The top is hinged with an opening and closing plate 35. When the rotating rod 26 rotates, it will drive the turntable 33 to rotate. Because the pull plate 36 and the turntable 33 are eccentrically set, when the turntable 33 rotates, it will push the moving frame 31 to slide on the surface of the slide plate 30 through the pull plate 36. When the slide plate 30 moves, it will drive the through hole frame 34 to move through the connection between the mounting frame 32 and the positioning plate 37. When the through hole frame 34 moves towards the feeding frame 7, the opening and closing plate 35 in the through hole frame 34 will be stuck on the surface of the through hole frame 34 due to the friction with the underwear fabric. At this time, when the through hole frame 34 moves, it cooperates with the opening and closing plate 35 to pull the underwear fabric.

[0040] There are two slide plates 30, which are symmetrically arranged around the feed rack 7. The ends of the slide plates 30 extend to the outer end of the feed rack 7. The through-hole frame 34 is located at the end of the feed rack 7 away from the discharge rack 6. When the through-hole frame 34 moves to the end away from the feed rack 7, the opening and closing plate 35 will be slightly open so that the through-hole frame 34 can slide on the surface of the underwear fabric. At this time, the through-hole frame 34 moves back and forth at the end of the feed rack 7 with the rotation of the turntable 33, and in the process of moving, it conveys the underwear fabric into the interior of the feed rack 7 to complete the conveying operation.

[0041] The end of the pull plate 36 near the turntable 33 is eccentrically positioned, the bottom of the opening and closing plate 35 extends to the bottom outer end of the through hole frame 34, and the turntable 33 is located at the end of the rotating rod 26 away from the gearbox 20.

[0042] The extrusion component 11 includes a limiting plate 40, an arc plate 42 fixedly connected to the end of the limiting plate 40, a connecting plate 47 fixedly connected to the surface of the limiting plate 40, a bidirectional electric push rod 43 fixedly connected to the surface of the connecting plate 47, the surface of the bidirectional electric push rod 43 fixedly connected to the surface of the support plate 3, a right-angle plate 46 fixedly connected to the surface of the right-angle plate 46, an electric rod 45 fixedly connected to the surface of the right-angle plate 46, and a circular hole ring 41 fixedly connected to the telescopic end of the electric rod 45. A groove 44 is provided at the end of the support plate 3 away from the motor 4. After the winding rod 2 finishes winding the underwear fabric, the bidirectional electric push rod 43 is activated to push the two connecting plates 47 to move closer to each other. When the connecting plates 47 move, they push the limiting plate 40 to slide inside the groove 44. The groove 44 limits the limiting plate 40 to improve the stability of the arc plate 42 during operation. When the arc plates 42 move closer to each other, they will extrude the underwear fabric.

[0043] There are two slides 44, which are symmetrically arranged with the winding rod 2 as the center. The end of the limiting plate 40 away from the arc plate 42 is in contact with the inner wall of the slide 44. The winding rod 2 is located inside the circular hole ring 41. The electric rod 45 is started to start the operation. The electric rod 45 pushes the circular hole ring 41 to move, and during the movement, it pushes the wound underwear fabric to separate from the surface of the winding rod 2, because the storage bag is covered on the surface of the arc plate 42.

[0044] The surface of the circular hole ring 41 is in contact with the surface of the support plate 3. There are two linkage plates 47, which are symmetrically arranged with the bidirectional electric push rod 43 as the center.

[0045] In use, the finished lingerie fabric is passed through the feed rack 7 and wound around the surface of the take-up rod 2. The motor 4 is then started to rotate the take-up rod 2 to wind the lingerie fabric. After the lingerie fabric is placed inside the feed rack 7, the power unit 21 is started to drive the rotating rod 26 to rotate inside the round hole rod 27. As the rotating rod 26 rotates, it drives the pusher plate 25 to rotate inside the feed rack 7 through the connection between the central rod 24 and the elastic rod 23. Inside the feed rack 7, there are two central rods 24, and the rotating rods 26 inside the two central rods 24 are connected by gears 22. At this time, the two rotating rods 26 rotate in opposite directions. The two central rods 24 cooperate to convey the lingerie fabric to one end of the discharge rack 6 through the pusher plate 25, allowing the lingerie fabric to be transported smoothly and efficiently. A small amount of fabric will accumulate at the end of the feed rack 7 near the output rack 6. When the winding rod 2 winds up the fabric, it easily pulls it out and winds it up, avoiding the need to pull the fabric during winding, which would cause the fabric to be in an elastically expanded state after winding, affecting the production quality of the underwear. Simultaneously, a gap is provided between the inner wall of the output rack 6 and the underwear fabric to prevent excessive friction between the fabric and the inner wall of the output rack 6, which would result in excessive tension during winding. The output rack 6 can also smooth out the underwear fabric. When the rotating rod 26 rotates, it drives the turntable 33 to rotate. Because the pull plate 36 and the turntable 33 are eccentrically set, the rotation of the turntable 33 pushes the moving frame 31 across the surface of the slide plate 30 via the pull plate 36. When the slide plate 30 moves, it drives the through-hole frame 34 to move through the connection between the mounting bracket 32 ​​and the positioning plate 37. When the through-hole frame 34 moves towards the feeding frame 7, the opening and closing plate 35 in the through-hole frame 34 will be stuck on the surface of the through-hole frame 34 due to the friction with the underwear fabric. At this time, the through-hole frame 34 and the opening and closing plate 35 cooperate to pull the underwear fabric and convey the underwear fabric into the inside of the feeding frame 7, improving the conveying efficiency of the pusher plate 25 for the underwear fabric and avoiding insufficient friction between the pusher plate 25 and the underwear fabric, which would affect the transmission effect. When the through-hole frame 34 moves away from the feeding frame 7, the opening and closing plate 35 will be in a slightly open state so that the through-hole frame 34 can slide on the surface of the underwear fabric. At this time, the through-hole frame 34 moves with the turntable 3 The rotation of rod 3 reciprocates at the end of the feeding rack 7, and during the movement, it conveys the underwear fabric into the inside of the feeding rack 7 to complete the conveying operation. This reduces the tension of the winding rod 2 on the underwear fabric during winding, preventing the underwear fabric from being in a state of elastic expansion for a long time, which would affect its quality. After the winding rod 2 has finished winding the underwear fabric, the bidirectional electric push rod 43 is activated to push the two connecting plates 47 to move closer to each other. When the connecting plates 47 move, they push the limiting plate 40 to slide inside the slide groove 44. The slide groove 44 limits the limiting plate 40, improving the stability of the arc plate 42 during operation. When the arc plates 42 move closer to each other, they will squeeze the underwear fabric. At this time, the storage bag can be put on the surface of the arc plate 42, and the electric rod 45 is activated to start the operation.The electric rod 45 pushes the circular ring 41 to move, and during the movement, it pushes the rolled-up underwear fabric to separate from the surface of the winding rod 2. Because the storage bag is fitted onto the surface of the arc plate 42, the underwear fabric separated from the winding rod 2 is directly pushed into the inside of the storage bag for storage, improving the convenience of packaging and transporting the underwear fabric.
