[0002] As a key material for photovoltaic modules to combat the PID effect, the slitting accuracy of film directly impacts the yield of downstream products. However, traditional slitting equipment faces technical bottlenecks in terms of rewinding efficiency and quantitative film winding control.

[0003] First, the existing slitting equipment is time-consuming and cumbersome to load and unload the rolls, making the overall process too complicated. Steps like unfastening bolts and replacing old rolls are time-consuming, significantly reducing work efficiency. Furthermore, during long-term operations, operators frequently touch the edges of the film, which can easily introduce dust or grease, negatively impacting product quality. Secondly, film lengths can often be customized to meet specific customer requirements. However, in practice, encoder measurement often overlooks the material's elastic deformation. During the rewinding phase, tension fluctuations can cause deviations between the film's actual length and the preset length, directly impacting the accuracy of length measurement.

[0014] A method for using a high-precision slitting device for producing anti-PID film, characterized in that the high-precision slitting device for producing anti-PID film according to any one of claims 1 to 9 is used to perform a film cutting operation, comprising: S1: Record the pre-load weight. Before rewinding, calculate and record the number of revolutions the rewinding roller needs to make and the weight converted from the film length. Then, place the rewinding roller in the placement rack. The lifting rack is lowered so that the lower end of the rewinding roller contacts the electronic scale. Record the weight of the unloaded rewinding roller. S2: Winding operation, the winding roller is reset and the two sets of sliding frames are driven close to each other, so that the motor 2 and the counter are connected to the winding roller. At this time, the motor 2 is running to drive the winding roller to rotate for the winding operation; S3: Primary calibration: Before winding, the number of turns that the winding roller needs to wind is recorded in the counter. When the counter records the appropriate number of turns, the winding operation is stopped. S4: Secondary calibration: After the counter records the appropriate number of turns, the lifting frame and the winding roller are driven down again to contact the electronic scale. The weight of the winding roller with the object is recorded and compared with the weight of the film length to be wound. If the difference is too large, the winding roller needs to be driven back or rewound. S5: Cutting operation: After two calibrations to obtain the precise length and weight of the winding roller, the cutter descends to contact the film and cuts the film by sliding the sliding block, completing the cutting operation. S6, discharge operation, after the cutting is completed, the lifting frame continues to rise, causing the push rod to push the limit rod to retract, so that the ejector rod can extend out of the lifting frame, and then the ejector rod continues to rise, pushing the winding roller out of the placement rack, and then the lifting frame descends, and the limit rod is pulled out to the lower end of the lifting frame, waiting for the second operation.

[0015] The technical effects achieved by the present invention are: The placement assembly and ejection assembly of the present invention can adjust the height of the winding roller according to needs so as to perform operations such as weighing or discharging. When in use, the winding roller is placed in the placement frame and placed on the lifting frame. Then, the placement assembly drives the lifting frame to lift and adjust the height of the winding roller so as to weigh the winding roller. When the winding roller needs to be discharged, after the lifting frame is raised to the top, the ejection rod will extend from the lifting frame and lift the winding roller out of the placement frame to discharge it, thereby realizing the lifting and discharging of the winding roller and improving the efficiency and effect of the work. The winding assembly of the present invention can be quickly connected to the winding roller and quickly disconnected as needed to facilitate height adjustment and quick loading and unloading. When in use, the two sets of sliding frames move away from each other along the inner cavity of the slide rail, so that the second motor and the counter are both away from the winding roller. At this time, the winding roller can be raised or lowered, and when it is necessary to connect to the winding roller, the two sets of sliding frames move closer to each other, so that the second motor and the counter are connected to the winding roller. At this time, the second motor can drive the winding roller to rotate for the winding operation, and the counter will also rotate synchronously with the winding roller to record the number of rotations of the winding roller, so as to record the length of the winding. The electronic scale, winding assembly and placement assembly of the present invention can verify whether the winding length meets the standard through double verification, avoiding the influence of tension on the winding length being too short, which affects the use; before winding, the empty winding roller will record the empty weight through the electronic scale, and when in use, the counter will record the number of rotations of the winding roller to judge whether it meets the standard. After the number of rotations meets the standard, the lifting frame will drop so that the lower end of the winding roller contacts the electronic scale. At this time, the total weight of the wound film can be subtracted from the empty weight to obtain the total weight of the wound film, which is converted into length by weight to judge whether the length of the wound film meets the standard, thereby improving the accuracy.

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0021] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0022] Example 1: Please refer to the attached Figure 1 、 Figures 4 to 10 、 Figures 12 to 13 As shown, this embodiment provides a high-precision slitting device for producing anti-PID film, comprising: The main body 10 has a storage rack 11 on the left side thereof and a conveying roller 14 in the inner cavity thereof; The placement assembly 20 includes a placement rack 21, which is fixedly connected to the upper end of the storage rack 11, and a lifting rack 23 is provided in the inner cavity of the placement rack 21, and a winding roller 25 is placed on the lifting rack 23; The ejection assembly 30 includes a push rod 32, which is disposed in the inner cavity of the placement rack 21. The inner cavity of the lifting rack 23 is provided with an ejection rod 35, and the lower end of the ejection rod 35 is provided with a limit rod 36; The winding assembly 40 includes a slide rail 41, which is disposed at the lower end of the storage rack 11. Slide racks 42 are disposed at both ends of the slide rail 41. A motor 45 is disposed on the slide rack 42 located at the front side of the storage rack 11, and a counter 48 is disposed on the slide rack 42 located at the rear side of the storage rack 11. The cutting assembly 50 includes a sliding block 52 , which is disposed above the main body 10 and has a cutter 56 disposed therein; An electronic scale 60, which is fixedly connected to the upper end of the storage rack 11; When the winding roller 25 is placed on the lifting frame 23, the lifting frame 23 descends so that the winding roller 25 contacts the electronic scale 60 to record the weight, and then rises so that the winding roller 25 is connected to the motor 2 45 and the counter 48. The counter 48 is used to record the number of rotations of the winding roller 25, and controls the lifting frame 23 to descend after the number of rotations is reached, so that the winding roller 25 contacts the electronic scale 60 again to obtain the weight of the film.

[0023] It should be noted that in order to prevent the electronic scale 60 from being unable to record the initial weight of the winding roller 25 due to the winding roller 25 being too thin, a replaceable tray should be provided on the electronic scale 60 to facilitate supporting both ends of the winding roller 25 for weighing; The upper end of the tray on the electronic scale 60 is an arc-shaped structure to prevent the winding roller 25 from sliding and affecting the weighing accuracy; Preferably, in order to ensure the accuracy of the second weighing, the winding operation should be stopped before the second weighing, but the conveying operation should not be stopped until the film becomes redundant on the right side of the winding roller 25, and then the conveying is stopped. At this time, when the second descending weighing is performed, the redundant film part is in a suspended state and cannot pull the winding roller 25, thereby avoiding the influence of the weighing data due to pulling the winding roller 25.

[0024] In this embodiment, during use, the winding roller 25 is placed in the placement rack 21. The lifting rack 23 then descends, bringing the unloaded winding roller 25 into contact with the electronic scale 60 to record the unloaded weight. The lifting rack 23 then ascends, returning the winding roller 25 to its original position, preparing for the winding process. During the winding process, the two sets of sliding racks 42 approach each other along the guide rails 41, connecting the drive sleeve 46 and counter 48 to the rotating shaft of the winding roller 25. Then, motor 2 45 drives the winding roller 25 to rotate, winding the film. Simultaneously, the counter 48 rotates synchronously with the winding roller 25, recording the number of revolutions of the winding roller 25 and thereby calculating the length of the film. When the number of revolutions recorded by the counter 48 reaches a preset value, motor 2 45 stops the winding process. At this point, the lifting rack 23 descends again, bringing the wound winding roller 25 into contact with the electronic scale 60 to record the weight of the load. By comparing the empty weight and the loaded weight, the weight of the wound film can be calculated, which is then converted into the length of the wound film and compared with the length recorded by the counter 48 to achieve double verification and ensure the accuracy of the wound length. If the difference in the comparison results is too large, it means that there may be an error in the winding process, and it is necessary to drive the winding roller 25 to reflow or rewind the film until the requirements are met. After the winding is completed, the cutting assembly 50 is started, the cutter 56 descends to contact the film, and the sliding block 52 slides to cut the film, completing the cutting operation. Subsequently, the ejection assembly 30 is started, and the lifting frame 23 continues to rise, causing the push rod 32 to push the limit rod 36 back, causing the ejection rod 35 to extend from the lifting frame 23, and eject the winding roller 25 out of the placement rack 21, completing the discharge operation.

[0025] Next, please refer to Figures 1 to 3 Two sets of long rods are provided on the side of the upper end of the storage rack 11 close to the main body 10, and the side of the two sets of long rods close to each other is rotatably connected to an auxiliary roller 12 through a ball bearing, and the middle part of the inner cavity of the main body 10 is rotatably connected to an auxiliary roller 2 13 through a ball bearing; There are two groups of conveying rollers 14, both of which are rotatably connected to the inner cavity of the main body 10 through ball bearings, and the rear ends of the two groups of conveying rollers 14 pass through the main body 10 and are fixedly connected to gears 15, and the outer rings of the two groups of gears 15 are meshed with each other. A motor 16 is fixedly installed at the rear end of the main body 10, and the output shaft of the motor 16 is fixedly connected to the center of the gear 15 located on the lower side. A mounting bracket 17 is fixedly installed at the upper end of the main body 10.

[0026] It should be noted that the outer rings of the two sets of conveying rollers 14 are provided with rubber anti-skid material pads; The main body 10 is provided with a protective shell on the outer ring of the gear 15 and the motor 16.

[0027] In this embodiment, motor 16 drives the lower gear 15 to rotate. Since the two sets of gears 15 mesh with each other, they drive the upper conveyor roller 14 to rotate synchronously, achieving synchronized conveying between the two sets of conveyor rollers 14. The film passes between the two sets of auxiliary rollers 12 and is then pulled onto the outer ring of the winding roller 25 for winding. The provision of auxiliary rollers 12 and 13 serves to guide and support the film.

[0028] Next, please refer to Figure 5 , Figures 9 and 10 , there are two groups of placement racks 21, which are respectively installed on the front and rear sides of the upper end of the storage rack 11. The placement assembly 20 also includes a lifting slot 22. The inner cavities of the two groups of placement racks 21 are both provided with lifting slots 22, and the inner cavities of the two groups of lifting slots 22 are both slidably connected with lifting racks 23; Hydraulic rods 24 are fixedly installed on the front and rear sides of the lower end of the storage rack 11 through auxiliary frames, and the upper ends of the two groups of hydraulic rods 24 pass through the storage rack 11 and the placement rack 21 and are placed below the corresponding lifting racks 23.

[0029] It should be noted that a slope is provided on the left side of the upper end of the placement rack 21, so that the subsequent winding roller 25 can be ejected and discharged by sliding down the slope. A stopper is provided at the upper end of the lifting slot 22 to limit the range of motion of the lifting frame 23; There are two groups of hydraulic rods 24 , which are connected in series. This is to control the two groups of hydraulic rods 24 to run synchronously, and to avoid the hydraulic rods 24 running one after the other, which may damage the winding roller 25 .

[0030] Preferably, in order to ensure the normal operation of the device, a set of receiving or transfer components should be provided on the left side of the storage rack 11, which is designed to receive the winding roller 25 discharged from the placement rack 21, so as to improve the transfer and efficiency.

[0031] In this embodiment, when in use, the winding roller 25 is placed in the placement rack 21 and placed in the lifting rack 23 , and then the hydraulic rod 24 is activated to control the lifting operation of the lifting rack 23 .

[0032] Next, please refer to Figures 10 to 14 The ejection assembly 30 also includes a groove 31, which is opened at the four corners of the outer ring of the lifting frame 23. Push rods 32 are slidably connected to the left and right sides of the upper end of the inner cavity of the placement frame 21, and the outer ring of the push rod 32 is in contact with the surface of the groove 31 and connected together. The ends of the two sets of push rods 32 facing the inner cavity of the placement frame 21 are fixedly connected to springs 1 33, and the other ends of the two sets of springs 1 33 are fixedly connected to the middle of the inner cavity of the placement frame 21; A through slot is provided in the middle of the lifting frame 23, and the upper end of the ejection rod 35 is slidably connected in the through slot. The ejection assembly 30 also includes a pushing frame 34, the lower end of the ejection rod 35 is fixedly connected to the middle of the upper end of the pushing frame 34, and the upper end of the hydraulic rod 24 is fixedly connected to the middle of the lower end of the pushing frame 34, the upper end and left and right sides of the pushing frame 34 are slidably connected to the inner cavity of the lifting frame 23, and empty slots are provided on the left and right sides of the lower end of the pushing frame 34, and the limit rods 36 are slidably connected in the empty slots, the part of the limit rod 36 extending out of the lower end of the pushing frame 34 is in contact with the lower end of the lifting frame 23, and one end of the two groups of limit rods 36 facing the inner cavity of the pushing frame 34 is fixedly connected to a spring 2 37, and the other ends of the two groups of springs 2 37 are fixedly connected to the middle of the inner cavity of the pushing frame 34.

[0033] It should be noted that the upper and lower ends of the ejector rod 35 are provided with slopes, and the groove 31 is also provided with a slope, so that when the lifting frame 23 is raised or lowered, the slope in the groove 31 can be used to push the ejector rod 35 back into the inner cavity of the placement frame 21; The extended length of the push rod 32 is greater than the distance between the lower ends of the push frame 34 and the inner wall of the placement frame 21, so that after the push rod 32 is fully extended, the limit rod 36 can be pushed back into the push frame 34; The elastic force of spring 1 33 should be greater than the contraction force of spring 2 37 , so that spring 1 33 can drive the push rod 32 to push the limit rod 36 to move; The upper end of the ejector rod 35 is provided with a slope, and the lower end of the slope is inclined to the left side of the placement rack 21. When fully extended, the height should be slightly higher than the upper end of the placement rack 21. This is so that after the ejector rod 35 completely ejects the winding roller 25, the slope at its upper end can be used to allow the winding roller 25 to slide to the left by gravity. The lower end of the limiting rod 36 is provided with a slope, and the lower end of the inner cavity of the lifting frame 23 is also provided with a slope. This is designed so that after the limiting rod 36 is retracted into the inner cavity of the lifting frame 23, during the descent process, the limiting rod 36 can be pushed back into the push frame 34 by relying on the slope on its surface, so that the lower end of the push frame 34 can be extended again from the lower end of the lifting frame 23. A square groove is formed at the lower end of the inner cavity of the placement frame 21. The depth of the square groove should be greater than the depth of the lower end of the push frame 34 that can extend out of the lifting frame 23. This is intended to limit the range of motion of the lifting frame 23. Even if the lifting frame 23 cannot descend, the push frame 34 can still rely on the square groove at the lower end to continue to descend, thereby pulling the limit rod 36 out of the lifting frame 23 to avoid affecting the ascent of the lifting frame 23. Two sets of semicircular bearings are provided on the inner ring of the upper end of the lifting frame 23 to assist the winding roller 25 in rotating.

[0034] In this embodiment, when the hydraulic rod 24 extends, it drives the push frame 34 and the limit rod 36 to rise synchronously, thereby driving the lifting frame 23 to rise. At this time, the upper end of the lifting frame 23 contacts the push rod 32, pushing it toward the inner cavity of the placement frame 21. At this time, the spring 1 33 is compressed. Then, it continues to rise until the outer end of the push rod 32 is placed at the lower end of the lifting frame 23. At this time, the spring 1 33 rebounds, driving the push rod 32 to extend outward, pushing the limit rod 36 into the push frame 34, allowing the push frame 34 to fully enter the inner cavity of the lifting frame 23. Continuing to rise, it can push the upper end of the ejection rod 35 out of the lifting frame 23, and then use the ejection rod 35 to eject the winding roller 25. When the hydraulic rod 24 contracts, it drives the push frame 34 and the lifting frame 23 downward. When the lifting frame 23 reaches the bottom, the push frame 34 continues to be driven downward. At this time, the limit rod 36 located in the inner cavity of the lifting frame 23 contacts the slope at the lower end of the inner cavity of the lifting frame 23 and uses the slope to push the limit rod 36 back into the inner cavity of the push frame 34. At this time, the lower end of the push frame 34 and the limit rod 36 can be separated from the inner cavity of the lifting frame 23. The rebound of the spring 2 37 pushes the limit rod 36 to re-engage the lower end of the lifting frame 23, thereby retracting the ejection rod 35 into the lifting frame 23 and driving the lifting frame 23 to rise again for the next operation. When the winding roller 25 is placed in the lifting frame 23, it is necessary to first drive the winding roller 25 downward to contact the electronic scale 60 to record the unloaded weight of the winding roller 25. Then, the lifting frame 23 drives the winding roller 25 to return to its original position and prepare for the winding operation. After the winding is completed, the winding roller 25 is controlled to descend again, contacting the electronic scale 60 to record the weight after winding, and subtracting the empty and full weights, converting the difference into length, and comparing it with the value of the counter 48 to achieve accurate control of the winding length. After the winding operation is completed, the winding roller 25 can be ejected by the ejection rod 35.

[0035] Please refer again Figures 5 to 8The slide rail 41 is installed in the middle of the lower end of the storage rack 11. The winding assembly 40 also includes a bidirectional motor 43. The output shafts on both sides of the bidirectional motor 43 are fixedly connected with screw rods 44, and the outer rings of the two sets of screw rods 44 are respectively threadedly connected to the middle of the lower ends of the two sets of sliding racks 42. Motor 2 45 is installed at the upper end of the front sliding rack 42, and the output shaft of motor 2 45 is fixedly connected with a drive sleeve 46. The drive sleeve 46 is movably inserted in the outer ring of the rotating shaft of the winding roller 25. The upper end of the sliding rack 42 located at the rear side is rotatably connected with a linkage sleeve 47 through a ball bearing. The linkage sleeve 47 is movably inserted in the outer ring of the rotating shaft at the rear end of the winding roller 25, and the rear end of the linkage sleeve 47 is engaged with a chain 49, and the lower end inner ring of the chain 49 is engaged with the rotating shaft of the counter 48.

[0036] It should be noted that a long rod is fixedly connected to the middle of the placement rack 21 on the front side, and the outer ring of the long rod is movably sleeved on the middle of the sliding rack 42 on the front side, in order to improve the sliding stability of the sliding rack 42; The bidirectional motor 43 is a motor with two sets of output shafts, and the spiral directions of the two sets of screw rods 44 are opposite, so that when the bidirectional motor 43 is running, it can simultaneously drive the two sets of sliding frames 42 to move closer or farther away; The counter 48 is an encoder that records the number of rotations of the linkage sleeve 47, and the rear ends of the counter 48 and the linkage sleeve 47 are both provided with sprockets, and the two sets of sprockets are connected together by a chain 49; The sliding frame 42 is provided with a protective shell in the area of ​​the chain 49 and the outer ring of the counter 48; The inner cavities of the drive sleeve 46 and the linkage sleeve 47 are both provided with hexagonal through grooves, and the entrance positions of the drive sleeve 46 and the linkage sleeve 47 are both rounded, and hexagonal blocks are also provided at both ends of the winding roller 25, so that the drive sleeve 46 and the linkage sleeve 47 can be quickly connected to the winding roller 25, and use the hexagonal structure to drive or rotate synchronously with the winding roller 25.

[0037] Preferably, in order to ensure the normal use of the device, cables should be set on the storage rack 11, and the mains electricity should be connected to each group of electrical equipment to provide energy for each group of electrical equipment.

[0038] In this embodiment, a bidirectional motor 43 rotates two sets of screws 44, driving the two sets of slide frames 42 toward or away from each other along the slide rails 41. When the winding roller 25 needs to be connected to the drive sleeve 46 and linkage sleeve 47, the bidirectional motor 43 drives the two sets of slide frames 42 toward each other until the drive sleeve 46 and linkage sleeve 47 are movably connected to the rotating shafts at the front and rear ends of the winding roller 25. At this point, the second motor 45 rotates the drive sleeve 46, driving the winding roller 25 to rotate synchronously, completing the film winding operation. Simultaneously, the linkage sleeve 47 rotates with the rotation of the winding roller 25, driving the rotating shaft of the counter 48 via the chain 49. The counter 48 records the number of rotations of the winding roller 25, thereby calculating the length of the wound film. When the predetermined winding length is reached, the second motor 45 stops, completing the winding operation. Subsequently, the bidirectional motor 43 is started again to drive the two sets of sliding frames 42 away from each other, so that the driving sleeve 46 and the linkage sleeve 47 are separated from the rotating shaft of the winding roller 25, preparing for the next winding operation.

[0039] Please refer again Figure 4 The cutting assembly 50 also includes an electric guide rail 51, which is mounted on the upper end of the inner cavity of the mounting frame 17, and a sliding block 52 is fixedly mounted on the slider in the inner cavity of the electric guide rail 51. An electric push rod 53 is fixedly mounted on the upper end of the inner cavity of the sliding block 52, and a lifting plate 54 is fixedly connected to the output end of the electric push rod 53. Extrusion wheels 55 are hinged on the left and right sides of the lower end of the lifting plate 54, and a cutter 56 is fixedly connected to the middle part of the lower end of the lifting plate 54.

[0040] It should be noted that the main body 10 is provided with a strip groove below the cutter 56 in order to improve the cutting effect of the cutter 56; The lower end of the sliding block 52 is provided with three sets of through slots, and the two sets of extrusion wheels 55 and the cutter 56 are extended out of the sliding block 52 through the through slots; The outer ring of the extrusion wheel 55 is provided with a rubber anti-skid pad, which is intended to limit and fix the two sides of the cutting part by using the extrusion wheel 55 during cutting; During the cutting operation, the conveying roller 14 and the winding roller 25 can be driven to run in opposite directions, thereby tightening the film under the cutter 56 to improve the cutting accuracy and effect.

[0041] In this embodiment, the electric push rod 53 drives the lifting plate 54 downward, simultaneously lowering the cutter 56 and the extrusion wheel 55 until the cutter 56 contacts the film. The sliding block 52 then slides within the electric guide rail 51, driving the cutter 56 to move and cut the film. Simultaneously, the extrusion wheel 55 positions the film on both sides of the cutting area to prevent it from shifting during cutting. Once the cut is complete, the electric push rod 53 drives the lifting plate 54 upward, simultaneously raising the cutter 56 and the extrusion wheel 55 and returning them to their initial positions, ready for the next cutting operation.

[0042] Example 2: A method for using a high-precision slitting device for producing anti-PID films, wherein the method is used to cut the films using the high-precision slitting device for producing anti-PID films, comprising: S1: Record the pre-load weight. Before winding, calculate and record the number of revolutions required for the winding roller 25 to wind the film and the weight converted from the film length. Then, place the winding roller 25 in the placement rack 21. Then, lower the lifting rack 23 so that the lower end of the winding roller 25 contacts the electronic scale 60. Record the weight of the unloaded winding roller 25. S2: Winding operation, the winding roller 25 is reset, and the two sets of sliding frames 42 are driven to approach each other, so that the second motor 45 and the counter 48 are connected to the winding roller 25. At this time, the second motor 45 is running to drive the winding roller 25 to rotate and perform the winding operation; S3: A primary check. Before winding, the number of turns that the winding roller 25 needs to wind is recorded in the counter 48. When the counter 48 records the appropriate number of turns, the winding operation is stopped. S4: Secondary verification. After the counter 48 records the appropriate number of turns, the lifting frame 23 and the winding roller 25 are driven down again to contact the electronic scale 60. The weight of the winding roller 25 with the load is recorded and compared with the weight of the film to be wound. If the difference is too large, the winding roller 25 needs to be driven back or wound again. S5: Cutting operation. After two checks to determine the precise length and weight of the film reeled by the reel 25, the cutter 56 descends to contact the film and cuts the film by sliding the sliding block 52, completing the cutting operation. S6, discharge operation, after the cutting is completed, the lifting frame 23 continues to rise, causing the push rod 32 to push the limit rod 36 to retract, so that the ejection rod 35 can extend out of the lifting frame 23, and then the ejection rod 35 continues to rise, pushing the winding roller 25 out of the placement rack 21, and then the lifting frame 23 descends, and the limit rod 36 is pulled out to the lower end of the lifting frame 23, waiting for the second operation.

[0043] In this embodiment, when performing S4 operation, if the data obtained is different from S3, the data requirements of S4 should be given priority. In this case, even if there is a difference from the original winding length, it will only be more than or equal to the original winding length, avoiding the difference being less than the predetermined length and affecting subsequent use.

[0044] The present invention operates as follows: the winding roller 25 is placed in the placement rack 21. The hydraulic rod 24 then drives the lifting frame 23 downward, bringing the unloaded winding roller 25 into contact with the electronic scale 60 and recording its unloaded weight. The lifting frame 23 then rises again, returning the winding roller 25 to its original position and preparing for the winding operation. A bidirectional motor 43 then rotates the two sets of screws 44, driving the two sets of slide frames 42 toward each other along the slide rails 41 until the drive sleeve 46 and linkage sleeve 47 are respectively attached to the shafts at the front and rear ends of the winding roller 25. At this point, the second motor 45 rotates the drive sleeve 46, driving the winding roller 25 to rotate synchronously, winding the film. Simultaneously, the linkage sleeve 47 rotates with the winding roller 25, driving the shaft of the counter 48 via the chain 49. The counter 48 records the number of revolutions of the winding roller 25, thereby calculating the length of the wound film. When the predetermined winding length is reached, the second motor 45 stops. The bidirectional motor 43 is activated again, driving the two sets of slides 42 away from each other, causing the drive sleeve 46 and linkage sleeve 47 to separate from the rotating shaft of the winding roller 25. This then drives the lifting frame 23 down again, bringing the winding roller 25 into contact with the electronic scale 60 to record the weight of the winding. The weight of the unloaded and fully loaded weights are subtracted, and the resulting difference is converted into a length. This is then compared with the value in the counter 48 to accurately control the winding length. The electric push rod 53 then drives the lifting plate 54 down, driving the cutter 56 and squeeze wheel 55 to descend synchronously until the cutter 56 contacts the film. The slide block 52 then slides within the electric guide rail 51, driving the cutter 56 to move and cut the film. Once cutting and winding are complete, the hydraulic rod 24 extends, driving the push frame 34 and limit rod 36 upward. The upper end of the lifting frame 23 now contacts the push rod 32, pushing it toward the inner cavity of the storage rack 21. The lifting mechanism 21 is lifted and the lifting frame 23 is lifted. The lifting mechanism 21 is lifted and the lifting frame 23 is lifted. The lifting mechanism 21 is lifted and the lifting frame 23 is lifted. The lifting mechanism 21 is lifted and the lifting frame 23 is lifted. The lifting mechanism 21 is lifted and the lifting frame 23 is lifted. The lifting mechanism 21 is lifted and the lifting frame 23 is lifted. The lifting mechanism 21 is lifted and the lifting frame 23 is lifted. The lifting mechanism 21 is lifted and the lifting frame 23 is lifted. Then the hydraulic rod 24 contracts, driving the pushing frame 34 and the lifting frame 23 to descend. When the lifting frame 23 moves to the bottom, the limiting rod 36 contacts the slope at the lower end of the inner cavity of the lifting frame 23 and uses the slope to push the limiting rod 36 back into the inner cavity of the pushing frame 34. At this time, the lower end of the pushing frame 34 and the limiting rod 36 can be separated from the inner cavity of the lifting frame 23 again, and the rebound of the spring 2 37 is used to push the limiting rod 36 to be stuck in the lower end of the lifting frame 23 again, waiting for the next operation.

It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention.
