Description

Technical Field

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

[0002] In the plastic film production process, a winding device is usually required to wind up the finished film.

[0003] Existing plastic film winding devices typically include a support base and a drive mechanism mounted on the support base. During use, the winding rollers are usually connected to the drive mechanism to transmit the driving force provided by the drive mechanism to the winding rollers, causing them to rotate. The rotating winding rollers then wind up the plastic film. However, in existing plastic film winding devices, once the length or diameter of the plastic film wound on the winding rollers meets the requirements, the winding operation of that set of winding rollers is complete. Afterward, the operator needs to remove this set of winding rollers and transfer them using a transport tool before using hoisting or other auxiliary tools to install new winding rollers and reconnect them to the drive mechanism to continue the winding operation. This operation method is complex, and the need for multiple tools reduces winding efficiency, thus reducing the production efficiency of plastic film. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a plastic film winding device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a plastic film winding device, comprising a support base and a winding roller, wherein the support base is provided with a driving mechanism for driving the winding roller to rotate, the driving mechanism comprising a driving column rotatably disposed on the support base, a rotating plate disposed on the driving column, a driving sleeve slidably disposed on the driving column, a driving friction plate cooperating with the winding roller disposed on the driving sleeve, a driving support rod rotatably disposed on the driving support rod, a driving slider rotatably disposed on the driving support rod and slidably connected to the rotating plate, a driving clamping block disposed on the driving slider, a power roller cooperating with the driving clamping block rotatably disposed on the support base, a synchronization mechanism for driving the driving friction plate to move disposed on the support base, a clamping mechanism for clamping the winding roller by opening and closing as the driving friction plate moves disposed on the support base, a placement box disposed on the support base, and a lower roller mechanism disposed on the placement box for causing the winding roller to fall one by one into the clamping mechanism as the driving friction plate moves.

[0006] As an improvement, the drive sleeve is provided with a movable rotating column connected to the drive friction plate. The movable rotating column has an H-shaped cross-section. The synchronization mechanism includes a synchronization slide plate that is slidably disposed on the support base. The synchronization slide plate is provided with a synchronization rack. The support base is provided with a synchronization gear that meshes with the synchronization rack. The synchronization slide plate is provided with a mating slide plate. The mating slide plate is provided with a drive lever. The drive lever rotates and engages with the movable rotating column.

[0007] As an improvement, the clamping mechanism includes a support frame mounted on a supporting base, a connecting slider slidably mounted on the support frame, a connecting rack mounted on the connecting slider, a clamping block symmetrically rotatably mounted on the support frame, a clamping gear on the clamping block meshing with the connecting rack, a clamping arm on the clamping block, a fixing rod mounted on the supporting base, a linkage rod rotatably mounted on the fixing rod and connected to the rotation of the drive lever, and a clamping connecting rod rotatably mounted on the connecting slider and connected to the linkage rod.

[0008] As an improvement, the lower roller mechanism includes a lower roller guide roller rotatably disposed in the placement box, a one-way rotating plate at one end of the lower roller guide roller, a positioning groove on the one-way rotating plate, a positioning spring in the positioning groove, a positioning slider connected to the positioning spring slidably disposed in the positioning groove, a mating rotating plate rotatably disposed on the supporting base, a key on the mating rotating plate engaging with the positioning slider, a lower roller gear on one side of the mating rotating plate, a lower roller bracket on the connecting slider, and a lower roller rack on the lower roller bracket engaging with the lower roller gear.

[0009] As an improvement, a guiding mechanism for guiding the plastic film is provided on one side of the supporting base. The guiding mechanism includes a horizontal guide roller and a vertical guide roller rotatably disposed on one side of the supporting base. The horizontal guide roller and the vertical guide roller are arranged perpendicular to each other.

[0010] As an improvement, the support base is equipped with a winding motor, the output end of the winding motor is equipped with a winding groove wheel, one side of the power roller is equipped with a power groove wheel, and a winding belt is provided between the winding groove wheel and the power groove wheel.

[0011] As an improvement, the placement box is provided with an adjustment mechanism that allows the take-up rollers to enter the lower guide rollers in sequence. The adjustment mechanism includes a support plate set in the placement box, an adjustment plate that slides on the support plate, a guide plate that is arc-shaped at one end of the adjustment plate, and an electric push rod that is connected to the adjustment plate at the output end of the electric push rod.

[0012] The advantages of this invention compared to existing technologies are as follows: The synchronizing mechanism drives the driving mechanisms to move away from each other. At this time, the winding roller on the driving mechanism, having completed its winding, falls under gravity to complete the winding. Afterwards, the synchronizing mechanism drives the clamping mechanism to close via the driving mechanism. During this process, the lower roller mechanism rotates, and a new winding roller falls to the clamping mechanism, thus continuing the winding operation of the plastic film. This conveniently realizes the placement, individual lowering, clamping, driving, and release of the winding rollers. It eliminates the need for manual disassembly and assembly of the winding rollers and the need for external tools to transfer them. The process is simple, improving the winding efficiency of plastic film and thus increasing the production efficiency of plastic film. Specifically:

[0013] 1. When the take-up roller needs to be wound up, the driving friction plate moves the positioning friction block closer to the take-up roller until the driving friction plate abuts against the take-up roller. The two sets of driving clamps move closer to each other until they abut against the power roller. At this time, the power of the power roller can be transmitted to the take-up roller through the driving friction plate, and the take-up roller can rotate to perform the winding operation. When the take-up roller needs to be released after winding is completed, the driving friction plate moves the positioning friction block away from the take-up roller until the driving friction plate separates from the take-up roller. At this time, the take-up roller falls under the action of gravity, the driving sleeve slides along the mating column, and the driving sleeve drives the driving slider to slide along the rotating plate through the driving support rod. The two sets of driving clamps move away from each other until they separate from the power roller. At this time, the take-up roller loses power and stops rotating. The switching between winding and unwinding can be achieved simply by moving the friction plate. No external tools are needed. The process is simple, easy to control, and improves the winding efficiency of plastic film.

[0014] 2. When the drive block moves closer to the clamping block, it drives the linkage rod to rotate. Simultaneously, the linkage rod rotates, causing the connecting slider to move downwards via the clamping linkage. The connecting rack moves downwards, and the connecting rack, through its meshing clamping gear, drives the clamping block to rotate and open. The clamping arm rotates and opens, allowing the take-up roller to fall under gravity. Conversely, when the drive block moves away from the clamping block, the connecting rack, through its meshing clamping gear, drives the clamping block to rotate and close, and the clamping arm rotates and closes. The closed clamping arm supports the take-up roller. No external power components are needed; the opening and closing states of the clamping arm can be switched simply by moving the drive block, thus conveniently clamping and releasing the take-up roller, further improving take-up and unwinding efficiency and increasing the production efficiency of plastic film.

[0015] 3. When the connecting slider moves upward, the lower roller bracket drives the lower roller rack to move upward synchronously, the lower roller gear rotates, and the rotating plate rotates synchronously. The rotating plate rotates in one direction through the engagement of the key and the positioning slide column, and the lower roller guide roller rotates synchronously. The take-up roller moves and falls between the clamping arms, which facilitates the subsequent take-up operation. Thus, after one take-up roller has finished taking up the film, the new take-up roller can be automatically released to the take-up point for take-up operation, improving the roller changing efficiency and further improving the take-up efficiency of plastic film.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Combined with appendix Figure 1 Appendix Figure 2 With appendix Figure 3As shown, a plastic film winding device includes a support base 1 and a winding roller 25. The support base 1 is provided with a drive mechanism 2 for driving the winding roller 25 to rotate. The support base 1 is provided with a synchronization mechanism 4 for driving the drive mechanism 2 to move. The support base 1 is provided with a clamping mechanism 3 for clamping the winding roller 25 by opening and closing as the drive mechanism 2 moves. The support base 1 is provided with a placement box 11. The placement box 11 is provided with a lower roller mechanism 6 for causing the winding roller 25 to fall one by one to the clamping mechanism 3 as the drive mechanism 2 moves. A guide mechanism 8 for guiding the plastic film is provided on one side of the support base 1. The guide mechanism 8 includes a horizontal guide roller 81 and a vertical guide roller 82 rotatably arranged on one side of the support base 1. There are at least two sets of horizontal guide rollers 81 and the vertical guide rollers 82 are symmetrically arranged. The horizontal guide rollers 81 and the vertical guide rollers 82 are arranged perpendicular to each other.

[0033] The working principle of this invention: Multiple sets of take-up rollers 25 are filled in the placement box 11. The lower roller mechanism 6 blocks the take-up rollers 25 to prevent them from falling under gravity. The synchronization mechanism 4 drives the drive mechanisms 2 to move away from each other. At this time, the take-up rollers 25 that have finished winding on the drive mechanism 2 fall under gravity to complete winding. Afterwards, the synchronization mechanism 4 drives the clamping mechanism 3 to close via the drive mechanism 2. During this process, the drive mechanism 2 drives the lower roller mechanism 6 to rotate, and one set of take-up rollers 25 falls to the clamping mechanism 3 under gravity. The synchronization mechanism 4 drives the drive mechanism 2 to approach each other and clamp and fix the take-up roller 25. During this process, the drive mechanism 2 drives the clamping mechanism 3 to open, and the lower roller mechanism 6 remains stationary. The plastic film passes through the vertical guide roller 82 and the horizontal guide roller 81 in sequence and is then wound onto the take-up roller 25, thereby performing the plastic film winding operation. There is no need for manual disassembly and assembly of the take-up roller 25, nor is there a need for external tools to transfer the take-up roller 25. The process is simple, which improves the winding efficiency of plastic film and the production efficiency of plastic film.

[0034] Combined with appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 With appendix Figure 14As shown, the driving mechanism 2 includes a driving column 21 rotatably mounted on the support base 1, a rotating plate 211 on the driving column 21, a rotating groove 2111 on the rotating plate 211, a mating column 212 on the rotating plate 211, a mating slider 2121 on the mating column 212, a driving sleeve 22 slidably mounted on the mating column 212, a driving friction plate 221 on the driving sleeve 22 that mates with the take-up roller 25, and a positioning friction block 2211 on the driving friction plate 221. Both sides of the roller 25 are provided with clamping grooves 251 that cooperate with the positioning friction block 2211. The drive sleeve 22 is rotatably provided with a drive support rod 223. The drive support rod 223 is rotatably provided with a drive slider 224 that is slidably connected to the rotating plate 211. The drive slider 224 is provided with a drive slide rail 226 that is slidably cooperated with the rotating slide groove 2111. The drive slider 224 is provided with a drive clamping block 225. The support base 1 is provided with a fixed plate. The fixed plate is rotatably provided with a power roller 23 that cooperates with the drive clamping block 225.

[0035] The support base 1 is equipped with a winding motor 24, and a winding groove wheel 241 is rotatably provided on the fixed plate. The output end of the winding motor 24 is connected to the winding groove wheel 241. A power groove wheel 231 is provided on one side of the power roller 23, and a winding belt 242 is provided between the winding groove wheel 241 and the power groove wheel 231.

[0036] Working principle of drive mechanism 2: The take-up motor 24 drives the take-up groove wheel 241 to rotate. The take-up groove wheel 241 drives the power groove wheel 231 to rotate through the take-up belt 242. When it is necessary to provide take-up power to the take-up roller 25, the drive friction plate 221 drives the positioning friction block 2211 to move closer to the take-up roller 25 until the drive friction plate 221 abuts against the take-up roller 25. The positioning friction block 2211 is engaged in the clamping groove 251. During this process, the drive sleeve 22 slides along the mating post 212. Due to the presence of the mating slider 2121, the drive sleeve 22 will not rotate. The drive sleeve 22 drives the drive slider 224 to slide along the rotating plate 211 through the drive support rod 223. The drive slide rail 226 slides along the drive slide groove. The two sets of drive clamps 225 move closer to each other until they abut against the power roller 23. At this time, the power of the power roller 23 can be transmitted to the take-up roller 25 through the drive friction plate 221, and the take-up roller 25 can rotate. Conversely, when it is necessary to release the take-up roller 25, the drive friction plate 221 drives the positioning friction block 2211 to move away from the take-up roller 25 until the drive friction plate 221 separates from the take-up roller 25. At this time, the take-up roller falls under the action of gravity. During this process, the drive sleeve 22 slides along the mating column 212. The drive sleeve 22 drives the drive slider 224 to slide along the rotating plate 211 through the drive support rod 223. The two sets of drive clamps 225 move away from each other until they separate from the power roller 23. At this time, the take-up roller 25 loses power and stops rotating.

[0037] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 11 With appendix Figure 13 As shown, the drive sleeve 22 is provided with a movable rotating column 222 connected to the drive friction plate 221. The movable rotating column 222 has an H-shaped cross-section. The synchronization mechanism 4 includes a synchronization slide plate 41 slidably disposed on the support base 1. Two sets of synchronization slide plates 41 are provided. The synchronization slide plate 41 is provided with a synchronization rack 411. The support base 1 is rotatably provided with a synchronization gear 43 that meshes with the synchronization rack 411. The synchronization gear 43 can be driven by a motor. The synchronization slide plate 41 is provided with a mating slide plate 42. The mating slide plate 42 is provided with a synchronization groove 421. The synchronization groove 421 on one set of synchronization slide plates 41 is slidably connected to the other set of synchronization slide plates 41. The mating slide plate 42 is provided with a drive lever 227. The drive lever 227 is rotatably engaged with the movable rotating column 222.

[0038] The supporting base 1 is provided with a feeding bracket 5, and the feeding bracket 5 is provided with a feeding groove 51 that slides with the winding roller 25. The feeding groove 51 has an arc-shaped structure, and a feeding baffle 52 is provided at one end of the feeding groove 51.

[0039] Working principle of synchronization mechanism 4: The motor drives the synchronization gear 43 to rotate. The synchronization gear 43 drives the synchronization slide plate 41 to move synchronously through the synchronization rack 411 meshing with it. The synchronization slide plate 41 slides relative to the corresponding synchronization groove 421. When the two sets of synchronization slide plates 41 approach each other, the synchronization slide plate 41 drives the drive block 227 to move through the mating slide plate 42 connected to it. The two sets of drive blocks 227 approach each other. The drive blocks 227 drive the drive friction plates 221 to approach each other through the moving rotating column 222. When the drive friction plates 221 abut against the take-up roller 25, the take-up roller 25 moves with the drive... The friction plate 221 rotates to perform winding. Conversely, when the two sets of synchronous slide plates 41 move away from each other, the synchronous slide plate 41 drives the drive block 227 to move through the connecting slide plate 42. The two sets of drive blocks 227 move away from each other, and the drive blocks 227 drive the friction plates 221 to move away from each other through the moving column 222. When the drive friction plate 221 separates from the winding roller 25, the winding roller 25 stops rotating and falls under the action of gravity. The winding roller falls into the feeding bracket 5 under the action of gravity and slides along the feeding chute 51 until it contacts the feeding baffle 52, completing the winding operation.

[0040] Combined with appendix Figure 3 Appendix Figure 5 Appendix Figure 7 With appendix Figure 8As shown, the clamping mechanism 3 includes a support frame 31 mounted on a support base 1, a connecting slider 32 slidably mounted on the support frame 31, a support groove 311 mounted on the support frame 31, a connecting slide rail 321 slidably engaged with the support groove 311 mounted on the connecting slider 32, a connecting rack 322 mounted on the connecting slider 32, two sets of connecting racks 322 symmetrically arranged, a clamping block 33 symmetrically rotatably mounted on the support frame 31, a clamping gear 331 meshing with the connecting rack 322 mounted on the clamping block 33, a clamping arm 332 mounted on the clamping block 33, a fixing rod 36 mounted on the support base 1, a linkage rod 35 rotatably mounted on the fixing rod 36 and rotatably connected to the drive lever 227, and a clamping connecting rod 34 rotatably mounted on the connecting slider 32 and rotatably connected to the linkage rod 35.

[0041] Working principle of clamping mechanism 3: When the drive block 227 moves closer to the clamping block 33, the drive block 227 drives the linkage rod 35 to rotate. At the same time, the linkage rod 35 rotates and drives the connecting slider 32 to move downward through the clamping connecting rod 34. The connecting slide rail 321 slides downward along the support slide groove 311, and the connecting rack 322 moves downward. The connecting rack 322 drives the clamping block 33 to rotate and open through the clamping gear 331 that meshes with it. The clamping arm 332 rotates and opens. At this time, the take-up roller 25 can fall under the action of gravity. Conversely, when the drive block 227 moves away from the clamping block 33, the drive block 227 drives the linkage rod 35 to rotate. At the same time, the linkage rod 35 rotates and drives the connecting slider 32 to move upward through the clamping linkage 34. The connecting slide rail 321 slides upward along the support slide groove 311, and the connecting rack 322 moves upward. The connecting rack 322 drives the clamping block 33 to rotate and close through the clamping gear 331 that meshes with it. The clamping arm 332 rotates and closes. At this time, the closed clamping arm 332 can support the take-up roller 25.

[0042] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 9 Appendix Figure 10 With appendix Figure 12As shown, the lower roller mechanism 6 includes a lower roller guide roller 61 rotatably disposed in the placement box 11. The lower roller guide roller 61 is provided with a lower roller guide groove 611. Multiple sets of lower roller guide grooves 611 are equidistantly arranged around the circumference of the lower roller guide roller 61. One end of the lower roller guide roller 61 is provided with a one-way rotating plate 62. The one-way rotating plate 62 is provided with a positioning groove 621. A positioning spring 622 is provided in the positioning groove 621. A positioning slider 623 connected to the positioning spring 622 is slidably disposed in the positioning groove 621. The positioning slider 623 has a wedge-shaped structure. The supporting base 1 is rotatably provided with a mating rotating plate 63. The mating rotating plate 63 is provided with a key that meshes with the positioning slider 623. A lower roller gear 631 is provided on one side of the mating rotating plate 63. The connecting slider 32 is provided with a lower roller bracket 64. The lower roller bracket 64 is provided with a lower roller rack 641 that meshes with the lower roller gear 631.

[0043] The placement box 11 is provided with an adjustment mechanism 7 that allows the take-up roller 25 to enter the lower guide roller 61 in sequence. The adjustment mechanism 7 includes a support plate 71 disposed in the placement box 11, an adjustment plate 73 slidably disposed on the support plate 71, a guide plate 731 disposed at one end of the adjustment plate 73, the guide plate 731 having an arc-shaped structure, and an electric push rod 72 disposed on the support plate 71, the output end of the electric push rod 72 being connected to the adjustment plate 73.

[0044] Working principle of the lower roller mechanism 6: The electric push rod 72 is operated to extend and retract, and the electric push rod 72 drives the adjusting plate 73 to move. The distance between the adjusting plate 73 and the support plate 71 is adjusted so that a single winding roller 25 can pass through, so that the winding roller 25 can enter the lower roller guide groove 611 on the lower roller guide roller 61 in sequence.

[0045] When the connecting slider 32 moves upward, the lower roller bracket 64 drives the lower roller rack 641 to move upward synchronously, the lower roller gear 631 rotates, and the lower roller gear 631 drives the mating rotating plate 63 to rotate synchronously. The mating rotating plate 63, through the engagement of the key with the positioning slide post, drives the one-way rotating plate 62 to rotate. The one-way rotating plate 62 drives the lower roller guide roller 61 connected to it to rotate, thereby moving the take-up roller 25 and dropping it between the clamping arms 332, facilitating subsequent take-up operations. Conversely, when the connecting slider 32 moves downward, the lower roller bracket 64 drives the lower roller rack 641 to move downward synchronously, the lower roller gear 631 rotates in the opposite direction, and the lower roller gear 631 drives the mating rotating plate 63 to rotate in the opposite direction synchronously. The mating rotating plate 63, through the key, presses the positioning slide post, and the positioning slide post slides downward along the positioning groove 621. The positioning slide post presses the positioning spring 622, and the positioning spring 622 contracts under force. At this time, the one-way rotating plate 62 remains stationary, thus blocking the take-up roller 25.

[0046] In a specific implementation of the present invention, the distance between the adjusting plate 73 and the support plate 71 is adjusted by the electric push rod 72, so that the take-up roller 25 can enter the lower roller guide roller 61 in sequence. Multiple sets of take-up rollers 25 are placed into the placement box 11. The take-up rollers 25 enter the lower roller guide groove 611 on the lower roller guide roller 61 in sequence. The take-up motor 24 is started, and the take-up motor 24 drives the power roller 23 to rotate. The motor drives the synchronous gear 43 to rotate, so that the synchronous slide plates 41 move closer or further away from each other synchronously. The synchronous slide plates 41 drive the corresponding mating slide plates 42 to move synchronously, and drive the toggle block 227 to move synchronously.

[0047] The drive blocks 227 are moved away from each other, and the drive friction plates 221 are moved away from each other. The two sets of clamping arms 332 are closed, the lower guide roller 61 rotates, and the take-up roller 25 falls onto the clamping arms 332 under the action of gravity. Then, the drive blocks 227 are brought closer to each other, and the drive friction plates 221 are brought closer to each other until they abut against the two ends of the take-up roller 25. The drive friction plates 221 drive the take-up roller 25 to rotate through friction, thereby completing the winding. At this time, the clamping arms 332 are separated. By repeating the above operation, the take-up roller 25 can be quickly replaced after it is finished winding, thus improving the winding efficiency of plastic film.

[0048] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
