Description

Technical Field

[0001] This invention relates to the field of plastic woven bag production technology, and in particular to a winding device for producing plastic woven bags. Background Technology

[0002] Plastic woven bags are made primarily from polypropylene resin, which is extruded and stretched into flat filaments, then woven and manufactured into bags. After weaving, the plastic woven bags need to be rolled up into rolls for storage or transport to the next stage of production.

[0003] Chinese utility model patent CN222159190U discloses a winding machine for plastic woven bags, including an L-shaped bracket, a hollow winding shaft with one end rotatably connected to the side wall of the L-shaped bracket, a rotating device for driving the rotation of the hollow winding shaft, a winding drum slidably sleeved on the hollow winding shaft, a pair of elongated holes opened on the side wall of the hollow winding shaft and communicating with its interior, a pair of elongated plates respectively slidably inserted into the two elongated holes, two pairs of fixing plates respectively fixed on the two elongated plates, two pairs of fixing slots respectively opened at both ends of the winding drum for the fixing plates to be inserted, a sliding rod sliding inside the hollow winding shaft and coaxial with the hollow winding shaft, a sliding device for driving the sliding rod to slide relative to the hollow winding shaft, and two pairs of connecting rods with one end jointly hinged to the side wall of the sliding rod and the other end respectively hinged to one side of the two elongated plates. The aforementioned winding machine uses a card plate and card slot type winding drum fixing method, which will not cause wear to the inner wall of the winding drum. Moreover, the structure is simple and stable, and the fixed winding drum is not prone to slippage or winding center deviation.

[0004] The winding machine disclosed in the aforementioned utility model patent winds up woven bags by rotating a hollow shaft and a winding drum. Because woven bags have a certain degree of flexibility, they are prone to wrinkling and piling up during the winding process, resulting in the woven bags forming a roll that is fluffy and bulky, which is not conducive to the transportation and storage of the roll. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a winding device for the production of plastic woven bags, which solves the problem that woven bags wrinkle during the winding process, resulting in a fluffy and bulky roll.

[0006] According to an embodiment of the present invention, a winding device for producing plastic woven bags includes a frame, on which a winding assembly, a pressing assembly, and a drive assembly are provided. The winding assembly includes a winding roller with detachable mounting seats at both ends, the two mounting seats being rotatably connected to the frame. The pressing assembly includes a first lifting plate movably mounted on the frame, with a rotatable pressing roller on the first lifting plate located directly above the winding roller. The drive assembly includes a drive motor, a first drive shaft, a second drive shaft, and a third drive shaft, the first drive shaft, the second drive shaft, and the third drive shaft being arranged horizontally and rotatably connected to the frame. The first drive shaft, second drive shaft, and third drive shaft are sequentially connected for transmission. The two ends of the first drive shaft are respectively engaged with a drive motor and one of the mounting seats. The drive assembly also includes a telescopic rod. The two ends of the telescopic rod are respectively provided with universal couplings, and the two universal couplings are respectively engaged with the second drive shaft and the pressure roller. The drive assembly also includes a lead screw, which is vertically mounted on the frame and rotatably connected to the frame. The third drive shaft is provided with a first bevel gear, and the lead screw is provided with a second bevel gear that meshes with the first bevel gear. The lead screw is provided with a first threaded part, and the first lifting plate is provided with a first threaded hole that mates with the first threaded part.

[0007] Compared with the prior art, the present invention has the following beneficial effects: The first drive shaft is driven by a drive motor to rotate, thereby rotating the mounting base and the winding roller to wind up the plastic woven bag. Simultaneously, the second and third drive shafts, which are connected to the first drive shaft, rotate synchronously, causing the pressing roller to rotate synchronously with the winding roller under the drive of the second drive shaft, pressing the plastic woven bag tightly onto the winding roller. This ensures a tight fit between the plastic woven bag and the winding roller, preventing wrinkles from forming. At the same time, the third drive shaft drives the lead screw to rotate, and through the engagement of the first threaded part and the first threaded hole, drives the first lifting plate to move vertically... The upward movement of the pressure roller causes it to gradually move away from the take-up roller as the diameter of the roll increases. This ensures that the plastic woven bag is continuously pressed against the take-up roller during the winding process. As the pressure roller rises, the telescopic rod gradually extends along with it. Through universal couplings at both ends of the telescopic rod, the pressure roller rotates smoothly under the drive of the second drive shaft. This solves the technical problem of wrinkles in the woven bag during winding, resulting in a fluffy and bulky roll. It also ensures that the plastic woven bag is tightly wound on the take-up roller, facilitating subsequent transportation and storage of the roll. Attached Figure Description

[0015] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention proposes a winding device for the production of plastic woven bags, which is used to wind up the woven plastic woven bags into rolls during the production process of plastic woven bags.

[0017] Please refer to Figure 1, Figure 2 and Figure 3The plastic woven bag production winding device includes a frame 100, on which a winding assembly 200, a pressing assembly 300, and a drive assembly 400 are mounted. The winding assembly 200 includes a winding roller 201, with detachable mounting seats 202 at both ends. The two mounting seats 202 are rotatably connected to the frame 100. During winding, the plastic woven bag is wound around the winding roller 201 to form a roll. The pressing assembly 300 includes a first lifting plate 301 that is vertically and vertically mounted on the frame 100. A rotatable pressing roller 302 is mounted on the first lifting plate 301 and is located directly above the winding roller 201. The pressing roller 302 is used to press the plastic woven bag tightly onto the winding roller 201 to prevent wrinkles from forming. The drive assembly 400 includes a drive motor 401, a first drive shaft 402, a second drive shaft 403, and a third drive shaft 404. The first drive shaft 402, the second drive shaft 403, and the third drive shaft 404 are respectively arranged horizontally and rotatably connected to the frame 100. The first drive shaft 402, the second drive shaft 403, and the third drive shaft 404 are sequentially connected for transmission. The opposite ends of the first drive shaft 402 are respectively engaged with the drive motor 401 and one of the mounting seats 202. When the first drive shaft 402 rotates under the drive of the drive motor 401, it drives the take-up roller 201 to rotate, so that the plastic woven bag can be wound on the take-up roller 201. The drive assembly 400 also includes a telescopic rod 405, with universal couplings 406 at opposite ends. The two universal couplings 406 are respectively matched with the second drive shaft 403 and the pressure roller 302. The second drive shaft 403 and the pressure roller 302 are connected through the telescopic rod 405 and the universal couplings 406, so that the pressure roller 302 rotates synchronously with the take-up roller 201, and the rotation direction of the pressure roller 302 is opposite to that of the take-up roller 201 to smooth the plastic woven bag. The drive assembly 400 further includes a lead screw 407, which is vertically mounted on the frame 100 and rotatably connected to the frame 100. The third drive shaft 404 is provided with a first bevel gear 408, and the lead screw 407 is provided with a second bevel gear 409 that meshes with the first bevel gear 408. The lead screw 407 is provided with a first threaded portion 410, and the first lifting plate 301 is provided with a first threaded hole that mates with the first threaded portion 410. When the third drive shaft 404 rotates, it drives the lead screw 407 to rotate and drives the first lifting plate 301 to rise vertically, so that the pressing roller 302 gradually moves away from the taking-up roller 201 as the diameter of the roll wound on the taking-up roller 201 increases, ensuring that the pressing roller 302 remains in contact with the plastic woven bag.

[0018] Specifically, the working process of the winding device for producing plastic woven bags provided in this embodiment when winding plastic woven bags is as follows: First, the winding roller 201 is installed on the mounting base 202. Then, the drive motor 401 is turned on to drive the first drive shaft 402 to rotate, thereby driving the winding roller 201 to rotate and winding the plastic woven bag. During the rotation of the first drive shaft 402, the second drive shaft 403 and the third drive shaft 404 rotate synchronously. The pressure roller 302 rotates synchronously with the winding roller 201 under the drive of the second drive shaft 403. The pressure roller 302 presses the plastic woven bag onto the winding roller 201 while smoothing the plastic woven bag, so that the plastic woven bag is tightly attached to the winding roller 201 to prevent wrinkles from forming. At the same time, the third drive shaft 404 drives the lead screw 407 to rotate and passes through the first drive shaft 404 to rotate the lead screw 407. The engagement of a threaded portion 410 with the first threaded hole drives the first lifting plate 301 to rise vertically, causing the pressure roller 302 to gradually move away from the take-up roller 201 as the diameter of the roll on the take-up roller 201 increases. This ensures that the plastic woven bag is continuously pressed against the take-up roller 201 by the pressure roller 302 during the winding process. As the pressure roller 302 rises, the telescopic rod 405 gradually extends with the movement of the pressure roller 302. Through the universal couplings 406 located at both ends of the telescopic rod 405, the pressure roller 302 rotates smoothly under the drive of the second drive shaft 403. After winding is completed, the drive motor 401 is turned off and the take-up roller 201 is removed from the mounting base 202. The take-up roller 201, along with the plastic woven bag, can then be removed from the plastic woven bag production winding device. The plastic woven bag production winding device provided in this embodiment uses the pressure roller 302 to press the plastic woven bag onto the winding roller 201, and the rotation of the pressure roller 302 flattens the plastic woven bag. The pressure roller 302 moves as the diameter of the roll increases, which prevents the plastic woven bag from wrinkling during the winding process, causing the roll to be fluffy and bulky. This ensures that the plastic woven bag is tightly wound on the winding roller 201, and facilitates the subsequent transportation and storage of the roll.

[0019] like Figure 2 and Figure 3As shown, the take-up roller 201 has a first flange 203 at each end, and the mounting base 202 has a second flange 204 that mates with the first flange 203. The take-up roller 201 is fixed to the mounting base 202 by bolting the first flange 203 onto the second flange 204, ensuring a secure connection between the take-up roller 201 and the mounting base 202 and preventing the take-up roller 201 from detaching from the mounting base 202 during the winding process. After winding is complete, the bolts are removed and the first flange 203 and the second flange 204 are separated, allowing the take-up roller 201 and the roll to be removed from the plastic woven bag production winding device. Then, other take-up rollers 201 can be replaced for continuous winding operations.

[0020] like Figure 3 As shown, the first lifting plate 301 is provided with a first lifting frame 303 that can be raised and lowered vertically and a first spring 304 that abuts against the first lifting frame 303. The pressure roller 302 is rotatably connected to the first lifting frame 303. The first spring 304 drives the first lifting frame 303 to move closer to the winding roller 201. By providing a movable first lifting frame 303 on the first lifting plate 301 for mounting the pressure roller 302, the pressure roller 302 can move vertically within a certain range relative to the first lifting plate 301. The elastic force provided by the first spring 304 keeps the pressure roller 302 in contact with the plastic woven bag, preventing the pressure roller 302 from detaching from the plastic woven bag during the winding process. This helps to improve the reliability of the winding device for plastic woven bag production.

[0021] Please refer to Figure 2 and Figure 3 The first drive shaft 402 is provided with a first gear 411, and the second drive shaft 403 is provided with a second gear 412 that meshes with the first gear 411. The first drive shaft 402 and the second drive shaft 403 are connected by the engagement of the first gear 411 and the second gear 412, ensuring that the power output by the drive motor 401 can be smoothly transmitted to the second drive shaft 403 and drive the second drive shaft 403 to rotate.

[0022] In this embodiment, a first sprocket 413 is provided on the second drive shaft 403, and a second sprocket 414 is provided on the third drive shaft 404. The first sprocket 413 and the second sprocket 414 are connected by a transmission chain 415. When the second drive shaft 403 rotates under the drive motor 401, the first sprocket 413, the transmission chain 415, and the second sprocket 414 transmit power to the third drive shaft 404, causing the third drive shaft 404 to rotate stably under the drive motor 401 and drive the first lifting plate 301 to move, thereby ensuring the stable operation of the winding device for producing plastic woven bags.

[0023] like Figure 3 and Figure 4 As shown, the telescopic rod 405 includes a first rod body 416 and a second rod body 417 sleeved on the first rod body 416. One end of the first rod body 416 is provided with an external spline 418, and the second rod body 417 is provided with an internal spline 419 that mates with the external spline 418. The first rod body 416 and the second rod body 417 are combined through the engagement of the external spline 418 and the internal spline 419, allowing the first rod body 416 to slide relative to the second rod body 417 to extend or shorten the telescopic rod 405. Simultaneously, the first rod body 416 and the second rod body 417 rotate synchronously under the drive of the second drive shaft 403, thereby ensuring that the power output by the drive motor 401 can be smoothly transmitted to the pressure roller 302 through the second drive shaft 403 and the telescopic rod 405.

[0024] Please combine Figure 1 , Figure 2 and Figure 3 The frame 100 is also provided with a support assembly 500. The support assembly 500 includes a second lifting plate 501 that can be lifted and lowered on the frame 100. The lead screw 407 is provided with a second threaded portion 420 and the rotation direction of the second threaded portion 420 is opposite to that of the first threaded portion 410. The second lifting plate 501 is provided with a second threaded hole that cooperates with the second threaded portion 420. Two support rollers 502 are spaced apart on the second lifting plate 501 and the support rollers 502 are located below the take-up roller 201. The support roller 502 is used to support the drum wound on the take-up roller 201. During the rotation of the lead screw 407, the second lifting plate 501 is driven to descend vertically, so that the support roller 502 moves synchronously away from the take-up roller 201 as the diameter of the drum increases, ensuring that the support roller 502 remains in contact with the drum. At the same time, the support roller 502 can support the drum during the disassembly of the take-up roller 201, preventing the drum from falling off during the removal of the take-up roller 201 from the mounting base 202.

[0025] In detail, the second lifting plate 501 is provided with a second lifting frame 503 that can be raised and lowered vertically and a second spring 504 that abuts against the second lifting frame 503. The support roller 502 is rotatably connected to the second lifting frame 503. The second spring 504 drives the second lifting frame 503 to move closer to the take-up roller 201. The support roller 502 is movably mounted on the second lifting plate 501 through the cooperation of the second lifting frame 503 and the second lifting plate 501. The elastic force provided by the second spring 504 keeps the support roller 502 in contact with the roll, preventing the support roller 502 from disengaging from the roll during the winding process of the plastic woven bag production take-up device, making the support assembly 500 more reliable.

[0026] like Figure 3 As shown, the frame 100 is also provided with a guide rail 101, the length direction of which is consistent with the vertical direction. The first lifting plate 301 and the second lifting plate 501 respectively cooperate with the guide rail 101. The first lifting plate 301 and the second lifting plate 501 are installed on the frame 100 through cooperation with the guide rail 101, and the guide rail 101 restricts the direction of movement of the first lifting plate 301 and the second lifting plate 501 on the frame 100, preventing the first lifting plate 301 and / or the second lifting plate 501 from deviating from the preset direction when moving, which helps to improve the structural stability of the winding device for producing plastic woven bags.

[0027] like Figure 1 and Figure 5 As shown, the frame 100 is also provided with a leveling component 600. The leveling component 600 includes a leveling seat 601 fixedly connected to the frame 100, and the leveling seat 601 is provided with a rotatable lower leveling roller 602. The lower leveling roller 602 is arranged parallel to the take-up roller 201. The leveling seat 601 is provided with a liftable first adjusting frame 603, and the first adjusting frame 603 is provided with a rotatable upper leveling roller 604. The upper leveling roller 604 is arranged parallel to the lower leveling roller 602. Before being wound onto the take-up roller 201, the plastic woven bag passes between the upper leveling roller 604 and the lower leveling roller 602. The upper leveling roller 604 and the lower leveling roller 602 flatten the plastic woven bag, preventing wrinkles from forming on the plastic woven bag when it reaches the take-up roller 201. The upper leveling roller 604 can move on the leveling seat 601 as the first adjusting frame 603 rises and falls, so as to adjust the distance between the upper leveling roller 604 and the lower leveling roller 602, making the leveling component 600 adaptable to plastic woven bags of various thicknesses.

[0028] Specifically, the leveling base 601 is also equipped with a first adjusting screw 605 and a third spring 606. The first adjusting screw 605 and the third spring 606 respectively abut against the upper and lower surfaces of the first adjusting frame 603. The third spring 606 is positioned at the bottom of the first adjusting frame 603 to support it, and the first adjusting screw 605 is positioned on the leveling base 601 to abut against the top of the first adjusting frame 603. When the first adjusting screw 605 rotates, it moves vertically on the leveling base 601. When the first adjusting screw 605 approaches the lower leveling roller 602, it pushes the first adjusting frame 603 and the upper leveling roller 604 closer to the lower leveling roller 602. At this time, the distance between the upper leveling roller 604 and the lower leveling roller 602 decreases, and the third spring... 606 is further compressed, and when the first adjusting screw 605 moves away from the lower leveling roller 602, the third spring 606 extends and pushes the first adjusting frame 603 and the upper leveling roller 604 away from the lower leveling roller 602 by the elastic force provided by the third spring 606. At this time, the distance between the upper leveling roller 604 and the lower leveling roller 602 increases. That is, rotating the second adjusting screw 705 can easily adjust the distance between the upper leveling roller 604 and the lower leveling roller 602 to match the thickness of the plastic woven bag, ensuring that the plastic woven bag remains flat when passing through the leveling component 600.

[0029] Please refer to Figure 5 The leveling component 600 further includes a first handle 607, which is fixedly connected to the first adjusting screw 605. By operating the first handle 607, the direction and number of rotations of the first adjusting screw 605 can be controlled, thereby controlling the direction and stroke of the lifting of the first adjusting frame 603, achieving precise adjustment of the position of the first adjusting frame 603.

[0030] Please refer to Figure 1 and Figure 6The frame 100 is also provided with a smoothing assembly 700. The smoothing assembly 700 includes a smoothing seat 701 fixedly connected to the frame 100, and a rotatable lower smoothing roller 702 is provided on the smoothing seat 701. The angle between the axis of the lower smoothing roller 702 and the axis of the take-up roller 201 is an acute angle. The smoothing seat 701 is provided with a liftable second adjusting frame 703, and a rotatable upper smoothing roller 704 is provided on the second adjusting frame 703. The upper smoothing roller 704 is arranged parallel to the lower smoothing roller 702. The smoothing component 700, through the upper smoothing roller 704 and the lower smoothing roller 702 positioned at an acute angle to the take-up roller 201, straightens and smooths the plastic woven bag during the conveying process of the plastic woven bag to the take-up roller 201, preventing wrinkles from forming during the conveying process. Furthermore, the distance between the upper smoothing roller 704 and the lower smoothing roller 702 can be adjusted by raising and lowering the second adjusting frame 703 on the smoothing seat 701, so that the distance between the upper smoothing roller 704 and the lower smoothing roller 702 is adapted to the thickness of the plastic woven bag, which helps to improve the versatility of the smoothing component 700.

[0031] In detail, the smoothing seat 701 is also provided with a second adjusting screw 705 and a fourth spring 706, which respectively abut against the upper and lower surfaces of the second adjusting frame 703. The fourth spring 706 provided on the smoothing seat 701 is used to support the second adjusting frame 703, and the height of the second adjusting frame 703 is adjusted by the second adjusting screw 705. When the second adjusting screw 705 rotates, it moves vertically on the smoothing seat 701. When the second adjusting screw 705 approaches the lower smoothing roller 702, it pushes the second adjusting frame 703 and the upper smoothing roller 704 closer to the lower smoothing roller 702. At this time, the upper smoothing roller 704... As the distance between the upper smoothing roller 702 and the lower smoothing roller 702 decreases, the fourth spring 706 is further compressed. When the second adjusting screw 705 moves away from the lower smoothing roller 702, the fourth spring 706 extends and pushes the second adjusting bracket 703 and the upper smoothing roller 704 away from the lower smoothing roller 702, thereby increasing the distance between the upper smoothing roller 704 and the lower smoothing roller 702. That is, rotating the second adjusting screw 705 can easily adjust the distance between the upper smoothing roller 704 and the lower smoothing roller 702.

[0032] like Figure 6As shown, the smoothing assembly 700 also includes a second handle 707, which is fixedly connected to the second adjusting screw 705. The second handle 707 is used to rotate the second adjusting screw 705, thereby adjusting the height of the second adjusting frame 703 to adapt the distance between the lower smoothing roller 702 and the upper smoothing roller 704 to the thickness of the plastic woven bag.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
