Description

Technical Field

[0001] This invention belongs to the field of flexible plastic film winding technology, and specifically relates to a winding device for flexible plastic film. Background Technology

[0002] With the rapid development of industries such as packaging, electronics, medical and agriculture, the demand for flexible plastic film is increasing day by day, which also puts forward higher requirements for its production efficiency and product quality. After the film casting, blow molding or stretching and other forming processes, winding is the last key process in production, which directly determines the final shape and quality of the product.

[0003] Currently, the winding devices commonly used in the industry are mostly dual-station rotary or swing-arm structures. When the film on the main winding roller reaches the preset length or diameter, the equipment stops operating. The film is cut and transferred to the prepared empty winding roller through a pneumatic or hydraulic drive mechanism. Then, the operator removes the fully wound roll from the shaft and reinstalls the empty core to prepare for the next switch. Since each roll switch requires the equipment to be stopped, the operation is cumbersome and limits the capacity improvement of the entire line. After winding and cutting, the surface of the fully wound flexible plastic film is not limited, and the outer film is prone to loosening and deformation during unwinding, affecting subsequent slitting and usage requirements. Summary of the Invention

[0004] In view of this, the present invention provides a winding device for flexible plastic film, which can achieve continuous winding and unwinding without stopping through automatic feeding, alternating switching of winding rollers, top pressing and compaction structure and rapid cutting mechanism, significantly improving production efficiency, while avoiding loose winding or deformation caused by inertia during unwinding, and ensuring stable finished product quality.

[0005] To solve the above-mentioned technical problems, the present invention provides a winding device for flexible plastic film, including a support frame and a winding mechanism disposed therein. The winding mechanism includes a rotating frame rotatably connected to one end of the inner cavity of the support frame. A top support assembly is provided between the two ends of the inner cavity of the rotating frame. The outer arc surface of the circular discs at both ends of the rotating frame is provided with a plurality of bearing slots. The other end of the support frame is provided with a feeding assembly that cooperates with the plurality of bearing slots. A plurality of auxiliary rollers are rotatably connected in each bearing slot. A motor is provided on one side of the support frame. The output shaft of the motor is fixedly connected to one end of the rotating frame. That is, through automatic feeding, alternating switching of the winding rollers, top pressing and compaction structure and rapid cutting mechanism, continuous winding and unloading without stopping are realized, significantly improving production efficiency, while avoiding loose winding or deformation caused by inertia during unloading, ensuring stable finished product quality.

[0006] The winding mechanism also includes a U-shaped plate located on the upper end of the support frame, near the top of the rotating frame. A mounting plate is slidably connected to the upper end of the U-shaped plate, and a cutting assembly is provided inside the mounting plate. Drive rollers are rotatably connected to the lower ends of both sides of the inner cavity of the mounting plate. A drive component is provided at one end of the mounting plate to drive one of the drive rollers to rotate. An electric telescopic rod is provided in the mounting opening at the upper end of the U-shaped plate. The lower end of the telescopic end of the electric telescopic rod is fixedly connected to the upper end of the mounting plate, thus achieving the winding function.

[0007] The winding mechanism also includes arc-shaped guide plates respectively set on the outer arc surfaces of the circular discs at both ends of the rotating frame on both sides of the inner cavity of the support frame. The center of the circle of the inner arc surface of the arc-shaped guide plate coincides with the center of the rotating frame, which serves as a limiting function.

[0008] The driving component includes a pulley 1 located at the outer end of one of the driving rollers. A second pulley is rotatably connected to the end of the mounting plate near the pulley 1. The second pulley and the pulley 1 are connected by belt drive. A second motor is located at the upper end of the mounting plate. The output shaft of the second motor is fixedly connected to one end of the second pulley, thus achieving the function of rapid driving.

[0009] The top support assembly includes several sliding grooves respectively set on the inner side of the circular discs at both ends of the rotating frame. The several sliding grooves are respectively set with the adjacent bearing grooves on the same side. Each sliding groove is slidably connected with a slider. A top roller is rotatably connected between two adjacent sliders at both ends. A spring is provided between the slider and the sliding groove it is in, so as to dynamically maintain the roll body tightly without gaps.

[0010] The feeding assembly includes electric conveyors symmetrically arranged at the other end of the support frame. Several placement seats are provided on the outer arc surface of the conveyor belts of the two electric conveyors. Guide plates are provided at the end of the two electric conveyors near the rotating frame, which serves as an automatic feeding function.

[0011] The feeding assembly also includes rollers placed between two adjacent placement seats at both ends. The outer arc surface of the rollers is provided with an adhesive layer, which is used to initially position the flexible plastic film.

[0012] The cutting assembly includes a sliding plate vertically slidably connected within a mounting plate. Sliding blades are slidably connected to symmetrically arranged slots at the lower end of the sliding plate. A drive plate is rotatably connected to the center of the top wall of the inner cavity of the sliding plate. Guide rods are provided at the center of the upper ends of the cutting blades. Guide openings at both ends of the sliding plate are movably engaged with adjacent guide rods on the same side. A third motor is located at the upper end of the sliding plate, and the output shaft of the third motor is rotatably connected to the upper end of the drive plate. An electric push rod is located on the mounting plate, and the telescopic end of the electric push rod is fixedly connected to the upper end of the sliding plate, thus enabling precise and rapid cutting of flexible plastic film.

[0013] It also includes a storage component, which includes a base frame located at the lower end of the support frame near the bottom of the rotating frame. Storage racks are provided on the upper sides of both ends of the base frame, which serves to facilitate quick storage.

[0014] The storage assembly also includes a mounting rod located on the inner side of the base frame cavity. Both ends of the outer arc surface of the mounting rod are equipped with spring clips to suppress loosening or inertial deformation of the roll.

[0015] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0016] 1. The feeding assembly feeds the film onto the roller. One end of the flexible plastic film is then fixed to the roller with an adhesive layer, ensuring the initial position of the flexible plastic film is stable. The electric telescopic rod then drives the mounting plate and its auxiliary mechanisms to move downwards, causing the two drive rollers to clamp the surface of the roller. The drive roller then rotates synchronously and cooperates with another drive roller, using friction to drive the roller to rotate at a constant speed, thus continuously winding the flexible plastic film. Simultaneously, when the flexible plastic film roll reaches a certain size, it will contact the top roller. At this time, the spring in the groove constantly presses against the outer layer of the wound film through the top roller, elastically contracting as the roll diameter increases, dynamically maintaining a tight roll without gaps. At the same time, during the uniform retraction of the electric telescopic rod, in conjunction with the continuous supply of film material, it prevents the roll from being too tight or too loose. When the roll diameter reaches... When the appropriate size is reached, the electric telescopic rod drives the mounting plate and its auxiliary mechanisms to reset. The motor drives the rotating frame to rotate 90 degrees, causing the fully wound roll to rotate 90 degrees synchronously under the constraint of the arc-shaped guide plate. Then, the feeding assembly operates again to move the empty roll to the take-up position. The electric telescopic rod then drives the mounting plate and its auxiliary mechanisms to move down again, so that the two drive rollers press the flexible plastic film onto the adhesive layer on the surface of the roll to fix it. Then, the cutting assembly precisely and quickly cuts the flexible plastic film, and then prepares for a new round of take-up, forming a fully automatic cycle of take-up, switching, and unwinding. Through automatic feeding, alternating roll switching, top-pressing and compacting structure, and rapid cutting mechanism, continuous take-up and unwinding without downtime are achieved, significantly improving production efficiency. At the same time, it avoids loose take-up or deformation caused by inertia during unwinding, ensuring stable finished product quality.

[0017] 2. The two electric conveyors run synchronously at a constant speed, thereby driving the waiting rollers on the placement seat to move synchronously. The foremost roller will detach from the placement seat due to gravity, be guided by the inclined guide plate, and slide precisely into the bearing slot at the top of the rotating frame. Then the two electric conveyors stop running synchronously, thereby realizing continuous feeding operation.

[0018] 3. The motor drives the plate to rotate. When the plate rotates, the guide rod moves the two dividing blades in opposite directions synchronously, thereby accurately and quickly cutting the flexible plastic film.

[0019] 4. When the fully rolled film moves to the bottom, it slides down onto the storage rack of the base frame under gravity. At this time, the spring contact touches the outer arc surface of the roll to inhibit loosening or inertial deformation.

[0020] 5. When motor 2 starts, its output shaft drives pulley 2 to rotate synchronously. When pulley 2 rotates, it drives pulley 1 and the drive roller fixedly connected to it to rotate synchronously through the belt. It also cooperates with another drive roller to drive the winding roller to rotate at a constant speed by using friction, so that the flexible plastic film is continuously wound by the winding roller.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figure 1-7The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0030] This embodiment provides a winding device for flexible plastic film, such as... Figure 1-7 The structure includes a support frame 100 and a winding mechanism disposed therein. The winding mechanism includes a rotating frame 200 rotatably connected to one end of the inner cavity of the support frame 100. A top support assembly is provided between the two ends of the inner cavity of the rotating frame 200. Several bearing slots 201 are provided on the outer arc surface of the circular discs at both ends of the rotating frame 200, and these bearing slots 201 are evenly distributed in a ring. A feeding assembly that cooperates with the bearing slots 201 is provided at the other end of the support frame 100. Several auxiliary rollers 202 are rotatably connected within each bearing slot 201. The auxiliary rollers 202 reduce the coefficient of friction and ensure smooth rotation. A motor 208 is provided on one side of the support frame 100, and the output shaft of the motor 208 is fixedly connected to one end of the rotating frame 200. The winding mechanism also includes components disposed on the support frame 100. The upper end of the frame 100 is near the top of the rotating frame 200, with a U-shaped plate 203. The upper end of the U-shaped plate 203 is slidably connected to a mounting plate 204. The mounting plate 204 is also equipped with a cutting assembly. The lower ends of both sides of the inner cavity of the mounting plate 204 are rotatably connected to drive rollers 205. One end of the mounting plate 204 is equipped with a drive component to drive one of the drive rollers 205 to rotate. An electric telescopic rod 206 is provided in the mounting opening at the upper end of the U-shaped plate 203. The lower end of the telescopic end of the electric telescopic rod 206 is fixedly connected to the upper end of the mounting plate 204. The winding mechanism also includes arc-shaped guide plates 207 respectively provided on both sides of the inner cavity of the support frame 100 near the outer arc surface of the circular discs at both ends of the rotating frame 200. The center of the circle of the inner arc surface of the arc-shaped guide plate 207 coincides with the center of the rotating frame 200.

[0031] The feeding assembly feeds the roll 503, then the electric telescopic rod 206 drives the mounting plate 204 and its auxiliary mechanisms to move downwards, causing the two drive rollers 205 to clamp the surface of the roll 503. The driving component then drives the fixedly connected drive roller 205 to rotate synchronously, cooperating with the other drive roller 205. Using friction, the roll 503 rotates at a constant speed, allowing the flexible plastic film to be continuously wound around it. Simultaneously, when the flexible plastic film roll reaches a certain size, it contacts the top support assembly. At this time, the top support assembly presses against the outer layer of the wound film, elastically contracting as the roll diameter increases, dynamically maintaining a tight, gapless roll. Meanwhile, during the uniform retraction of the electric telescopic rod 206, in conjunction with the continuous supply of film material, it prevents the roll from becoming too tight or too loose. When the roll diameter reaches the appropriate size, the electric telescopic rod 206 drives the mounting plate 204 and its auxiliary mechanisms to reset, and the motor... The drive frame 200 rotates 90 degrees, causing the fully wound roller 503 to rotate 90 degrees synchronously under the constraint of the arc-shaped guide plate 207. Then, the feeding assembly moves the empty roller 503 to the winding position again. Then, the electric telescopic rod 206 drives the mounting plate 204 and its auxiliary mechanisms to move down again, so that the drive rollers 205 on both sides press the flexible plastic film onto the adhesive layer 504 on the surface of the roller 503 for fixation. Then, the cutting assembly precisely and quickly cuts the flexible plastic film, and then prepares for a new round of winding. The fully wound film is constantly under the continuous light pressure of the top support assembly to ensure its tightness, forming a fully automatic cycle of winding, switching and unwinding. Through automatic feeding, alternating switching of the roller 503, top pressure and tightness structure and rapid cutting mechanism, continuous winding and unwinding without stopping are achieved, which significantly improves production efficiency, while avoiding loose winding or deformation caused by inertia during unwinding, ensuring stable finished product quality.

[0032] like Figure 1-5 As shown, the driving component includes a pulley 300 located at the outer end of one of the driving rollers 205. A second pulley 301 is rotatably connected to one end of the mounting plate 204 near the pulley 300. The second pulley 301 and the pulley 300 are connected by a belt drive. A second motor 302 is provided at the upper end of the mounting plate 204. The output shaft of the second motor 302 is fixedly connected to one end of the second pulley 301.

[0033] When motor 2 302 starts, its output shaft drives pulley 2 301 to rotate synchronously. When pulley 2 301 rotates, it drives pulley 1 300 and drive roller 205 fixedly connected to it to rotate synchronously through the belt. It also cooperates with another drive roller 205 to drive the winding roller 503 to rotate at a constant speed by using friction, so that the flexible plastic film is continuously wound by the winding roller 503.

[0034] like Figure 1-4As shown, the top support assembly includes several sliding grooves 400 respectively disposed on the inner side of the circular discs at both ends of the rotating frame 200. The several sliding grooves 400 are respectively disposed corresponding to the adjacent bearing grooves 201 on the same side. A slider 401 is slidably connected in each sliding groove 400. A top roller 402 is rotatably connected between two adjacent sliders 401 at both ends. A spring 403 is provided between the slider 401 and the sliding groove 400 it is located in.

[0035] When the flexible plastic film roll reaches a certain specification, it will come into contact with the top roller 402. At this time, the spring 403 in the chute 400 will always press the outer layer of the wound film through the top roller 402. As the roll diameter increases, it will elastically contract and dynamically maintain the roll body tightly without gaps.

[0036] like Figure 1-4 As shown, the feeding assembly includes electric conveyors 500 symmetrically arranged at the other end of the support frame 100. Each of the two electric conveyors 500 has several placement seats 501 on the outer arc surface of the conveyor belt. Each of the two electric conveyors 500 has a guide plate 502 at one end near the rotating frame 200. The feeding assembly also includes a roller 503 placed between two adjacent placement seats 501 at both ends. The outer arc surface of the roller 503 is provided with an adhesive layer 504. The auxiliary roller 202 reduces the coefficient of friction and ensures the smooth rotation of the roller 503.

[0037] Two electric conveyors 500 operate synchronously and at a constant speed, thereby driving the standby rollers 503 on the placement seat 501 to move synchronously. The foremost roller 503 will detach from the placement seat 501 due to gravity, be guided by the inclined guide plate 502, and slide precisely into the bearing slot 201 at the top of the rotating frame 200. Then the two electric conveyors 500 stop operating synchronously, thereby realizing continuous feeding operation.

[0038] like Figure 1-7 As shown, the cutting assembly includes a sliding plate 600 vertically slidably connected within the mounting plate 204. Sliding blades 601 are slidably connected to symmetrically arranged slots at the lower end of the sliding plate 600. A drive plate 602 is rotatably connected to the center of the top wall of the inner cavity of the sliding plate 600. Guide rods 603 are provided at the center of the upper end of each of the dividing blades 601. Guide openings at both ends of the sliding plate 600 are movably engaged with adjacent guide rods 603 on the same side. A motor 604 is provided at the upper end of the sliding plate 600. The output shaft of the motor 604 is rotatably connected to the upper end of the drive plate 602. An electric push rod 605 is provided on the mounting plate 204. The telescopic end of the electric push rod 605 is fixedly connected to the upper end of the sliding plate 600. The lower end of the dividing blades 601 has evenly distributed cutting edges.

[0039] Motor 604 drives drive plate 602 to rotate. When drive plate 602 rotates, it moves two dividing blades 601 synchronously in opposite directions through guide rod 603, thereby accurately and quickly cutting the flexible plastic film. After cutting, each mechanism resets.

[0040] like Figure 1-4 As shown, it also includes a storage component, which includes a base frame 700 located at the lower end of the support frame 100 near the bottom of the rotating frame 200. Storage racks 701 are provided on the upper sides of both ends of the base frame 700. The storage racks 701 have a U-shaped structure to prevent the fully rolled film from sliding out of the storage area. An installation rod 702 is provided on the inner side of the inner cavity of the base frame 700. Spring pieces 703 are provided on both ends of the outer arc surface of the installation rod 702.

[0041] When the full roll of film moves to the bottom, it slides down onto the storage rack 701 of the base frame 700 under gravity. At this time, the spring sheet 703 abuts against the outer arc surface of the roll to suppress loosening or inertial deformation.

[0042] The working principle of the flexible plastic film winding device provided by this invention is as follows: Two electric conveyors 500 run synchronously at a uniform speed, thereby driving the waiting rolls 503 on the placement seat 501 to move synchronously. The foremost roll 503 will detach from the placement seat 501 due to gravity, be guided by the inclined guide plate 502, and accurately slide into the bearing slot 201 at the top of the rotating frame 200. Then, the two electric conveyors 500 stop running synchronously. Subsequently, one end of the flexible plastic film is fixed to the roll 503 by the adhesive layer 504 to ensure the initial position of the flexible plastic film is stable. Then, the electric telescopic rod 206 is activated to drive the mounting plate 204 and its auxiliary mechanism to move down, thereby causing the drive rollers 205 on both sides to clamp the roll. On surface 503, motor 302 starts, and its output shaft drives pulley 301 to rotate synchronously. As pulley 301 rotates, it drives pulley 300 and the drive roller 205 fixedly connected to it to rotate synchronously via a belt. This, in conjunction with another drive roller 205, uses friction to drive the winding roller 503 to rotate at a constant speed, thus continuously winding the flexible plastic film. Simultaneously, when the flexible plastic film roll reaches a certain size, it contacts the top roller 402. At this time, the spring 403 in the groove 400 constantly presses against the outer layer of the wound film through the top roller 402, elastically contracting as the roll diameter increases, dynamically maintaining a tight, gapless roll. Meanwhile, the electric telescopic rod 206 retracts at a constant speed. To ensure continuous supply of film raw materials and prevent over- or under-winding, when the roll diameter reaches the appropriate size, the electric telescopic rod 206 drives the mounting plate 204 and its auxiliary mechanisms to reset. Motor 1 208 drives the rotating frame 200 to rotate 90 degrees, causing the fully wound roll 503 to rotate synchronously 90 degrees under the constraint of the arc-shaped guide plate 207. Then, the two electric conveyors 500 run synchronously and at a uniform speed again, moving the empty roll 503 to the take-up position. The electric telescopic rod 206 then drives the mounting plate 204 and its auxiliary mechanisms to move downwards again, causing the drive rollers 205 on both sides to press the flexible plastic film onto the adhesive layer 504 on the surface of the roll 503 for fixation. Then, motor 3 604 drives the drive plate 602 to rotate. 2. During rotation, the guide rod 603 moves the two dividing blades 601 synchronously in opposite directions, thereby accurately and quickly cutting the flexible plastic film. Then, a new round of winding is prepared. The full roll of film is constantly under the light pressure of the top roller 402 to ensure its compactness. When the full roll of film moves to the bottom, it slides down onto the storage rack 701 of the base frame 700 under gravity. At this time, the spring sheet 703 abuts against the outer arc surface of the roll to suppress loosening or inertial deformation, forming a fully automatic cycle of winding, switching, and unwinding. Through automatic feeding, alternating switching of the winding rollers 503, top pressure compaction structure, and rapid cutting mechanism, continuous winding and unwinding without stopping are achieved, significantly improving production efficiency. At the same time, it avoids loose winding or deformation caused by inertia during unwinding, ensuring stable finished product quality.

[0043] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0044] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
