Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to a heavy-duty winding arm device for a slitting machine. Background Technology

[0002] A slitting machine is a device that cuts wide materials into multiple narrow strips. During operation, several side-by-side winding assemblies wind the slit material into several slit film rolls. Currently, the winding assembly of a slitting machine typically includes two winding arms equipped with winding chucks. One winding arm is driven, and the other is non-driven. The driven winding arm has a motor that drives the corresponding winding chuck to rotate, while the non-driven winding arm's winding chuck is not powered. In practical applications, the winding assembly clamps the winding core cylinder using the winding chucks on the two winding arms, with the chucks extending into the inner holes at both ends of the core cylinder. Then, the motor on the driven winding arm drives the winding chucks to rotate, winding the slit material into slit film rolls.

[0003] Current slitting machines' winding assemblies rely solely on a motor on the winding arm to drive the winding core. For large-diameter, high-weight film rolls (slitting rolls can reach 1.5 meters in diameter and weigh 1-2 tons), insufficient driving force during the later stages of winding, as the roll diameter and weight increase, can negatively impact winding efficiency and quality. For example, Chinese Patent Publication No. CN116424936B, an invention titled "Slitting and Winding Machine," also uses a single winding motor to wind multiple narrow strips of material after slitting, and suffers from the same problem.

[0004] On the other hand, the motors in the winding assembly of current slitting machines are generally located on the outside of the winding arm, occupying a certain space between two adjacent winding assemblies, which affects the compactness of the layout structure of the two adjacent winding assemblies. Utility Model Content

[0005] The purpose of this invention is to provide a heavy-duty winding arm device for a slitting machine that is not only suitable for applications involving large-mass film rolls, providing sufficient driving force for winding large-mass film rolls, but also adaptable to winding film rolls with smaller widths, and conducive to improving the compactness of the layout structure between the winding components.

[0006] The technical solution of this utility model is: A heavy-duty take-up arm device for a slitting machine, comprising: The base has horizontally distributed tracks; Several winding assemblies are sequentially distributed along the track. Each winding assembly includes: Two winding arms that slide along the track; Each winding clamp, corresponding to a winding arm, is rotatably mounted on the top of the winding arm via a drive shaft. The winding drive mechanism, corresponding to each winding arm, includes a winding motor located at the bottom of the winding arm and a belt drive mechanism connecting the winding motor and the drive shaft. The winding motors of the same winding assembly are located between the two winding arms, and the winding motors on the two winding arms of the same winding assembly are staggered in the direction perpendicular to the track. The winding arm of the heavy-duty winding arm device of a slitting machine in this solution adopts a dual-drive design. Each winding arm of the winding assembly is equipped with a winding motor for driving the rotation of the winding chuck. Thus, during the winding process, the winding motors of the two winding drive mechanisms can drive the same winding film roll to rotate, providing double the winding drive force. This is particularly suitable for large-diameter, high-weight winding film rolls (the diameter of the slit winding film roll can reach 1.5 meters, and the weight can reach 1-2 tons). In the later stages of winding the slit material, as the diameter and weight of the film roll increase, it ensures double the winding drive force, avoiding insufficient winding drive force that could affect winding efficiency and quality.

[0007] Meanwhile, since the two take-up motors of the same take-up assembly are located between the two take-up arms, and the take-up motors on the two take-up arms of the same take-up assembly are staggered in the direction perpendicular to the track, this avoids the problem of the take-up motors being located outside the take-up arms and occupying the space between two adjacent take-up assemblies, thus affecting the compactness of the layout structure of the two adjacent take-up assemblies and improving the structural compactness of the distribution of each take-up assembly along the track. On the other hand, since the take-up motors are arranged between the two take-up arms of the same take-up assembly, the take-up motors occupy a certain space between the two take-up arms. When the two take-up arms of the same take-up assembly are close to each other, they will be affected by the take-up motors. In order to reduce the impact of the take-up motors on the closeness of the two take-up arms of the same take-up assembly, this solution staggers the take-up motors on the two take-up arms of the same take-up assembly in the direction perpendicular to the track. In this way, the two take-up arms of the same take-up assembly can be brought closer together, so that the film rolls with smaller widths can be wound between the two take-up arms of the take-up assembly, thus accommodating the winding of film rolls with smaller widths.

[0008] Preferably, the assembly also includes a plug shaft, with the drive shafts on the winding arms of each winding assembly being coaxially distributed, and each drive shaft having a plug hole that mates with the plug shaft. The openings of the plug holes on the drive shafts of the two winding arms of the same winding assembly are distributed facing away from each other. When two adjacent take-up assemblies approach each other, the insertion shaft can be simultaneously inserted into the insertion holes of two adjacent take-up arms in the two take-up assemblies. Once inserted, the insertion shaft and the insertion hole cannot rotate relative to each other. This allows for a greater winding drive force to be provided between the two take-up arms of the same take-up assembly, accommodating the winding of film rolls with larger diameters and weights. Specifically, When the winding motors on the two winding arms of a winding assembly (hereinafter referred to as the working winding assembly) that is in the winding operation still experience insufficient winding drive force while driving the film roll to rotate, an adjacent winding assembly (which is not in the winding operation, hereinafter referred to as the non-working winding assembly) can be brought close to the working winding assembly and its insertion shaft can be inserted into the insertion holes of two adjacent winding arms of the two winding assemblies. In this way, the winding motor on one winding arm of the adjacent non-working winding assembly can also provide winding drive force to the working winding assembly, that is, it can provide three times the winding drive force to the working winding assembly (three winding motors provide winding drive force simultaneously), in order to adapt to the winding of film rolls with larger diameters and weights. If three times the winding drive force is still insufficient, the two non-working winding assemblies adjacent to the working winding assembly can be brought closer to the working winding assembly. One insertion shaft is inserted into the insertion holes of two adjacent winding arms in the working winding assembly and the left non-working winding assembly, and another insertion shaft is inserted into the insertion holes of two adjacent winding arms in the working winding assembly and the right non-working winding assembly. In this way, the winding motor on one winding arm in each of the two adjacent left and right non-working winding assemblies can also provide winding drive force to the working winding assembly, which can provide four times the winding drive force to the working winding assembly (four winding motors provide winding drive force simultaneously), in order to accommodate the winding of film rolls with larger diameters and weights.

[0009] Preferably, the inner wall of the insertion hole is provided with a keyway, and the insertion shaft is provided with a corresponding convex key; or the cross-section of the insertion hole is a regular polygon, and the cross-section of the insertion shaft is also a regular polygon. In this way, after the insertion shaft is inserted into the insertion hole, the insertion shaft and the insertion hole cannot rotate relative to each other, ensuring that the drive shafts of the two adjacent winding arms in two adjacent winding assemblies can stably transmit power through the insertion shaft.

[0010] Preferably, the system also includes a translation drive mechanism, which comprises: The rack is fixed to the base and parallel to the track; The gears correspond one-to-one with the take-up arms and are located at the bottom of the corresponding take-up arms. The gears mesh with the racks. Each take-up arm is paired with a corresponding shift motor, which is fixed to the bottom of the take-up arm and drives the corresponding gear to rotate. In this way, each take-up arm can be driven by the shift motor to rotate the gear, thereby moving the take-up arm along the track. The displacement of the take-up arm can be precisely controlled by controlling the rotation angle of the shift motor.

[0011] Preferably, the winding motors on the two winding arms of the same winding assembly are located at the same height, and the winding motors on the two winding arms of a winding assembly are staggered horizontally upwards perpendicular to the track. The winding motors on both winding arms of this same winding assembly can be arranged at the bottom of the winding arm, thereby lowering the overall center of gravity of the winding arm and improving its movement stability.

[0012] Preferably, the take-up arm has a receiving cavity, and the belt drive mechanism is located in the receiving cavity of the corresponding take-up arm. This effectively improves the structural compactness of the take-up assembly itself, and at the same time, it avoids the belt drive mechanism occupying the space outside the take-up arm, thus preventing it from affecting the compact layout of two adjacent take-up assemblies.

[0013] Preferably, the belt drive mechanism is a synchronous belt drive mechanism, which also includes a tension pulley, which is also located in the receiving cavity of the corresponding take-up arm.

[0014] Preferably, the take-up arm is also equipped with a motor baffle, with the take-up motor located below the baffle and the baffle close to the take-up motor. This protects the take-up motor and prevents the film roll from colliding with it.

[0015] Preferably, the width of the take-up arm gradually increases from top to bottom. This improves the structural stability of the take-up arm and lowers its overall center of gravity, which in turn enhances its movement stability.

[0016] Preferably, the drive shaft is rotatably mounted on the top of the take-up arm via a bearing, and the drive shaft is parallel to the track.

[0017] The beneficial effects of this utility model are: Firstly, the winding arm of the winding assembly adopts a dual-drive design. Each winding arm of the winding assembly is equipped with a winding motor for driving the winding chuck to rotate. In this way, during the winding process, the winding motors of the two winding drive mechanisms can drive the same winding film roll to rotate, providing double the winding driving force. This is especially suitable for winding film rolls with large diameter and high weight (the diameter of the slit winding film roll can reach 1.5 meters and the weight can reach 1-2 tons). In the later stage of winding the slit material, as the diameter and weight of the film roll increase, it ensures that double the winding driving force is provided for winding, avoiding the problem of insufficient winding driving force, which affects winding efficiency and winding quality.

[0018] Secondly, since the two winding motors of the same winding assembly are located between the two winding arms, and the winding motors on the two winding arms of the same winding assembly are staggered in the direction perpendicular to the track, this avoids the problem of the winding motors being located outside the winding arms and occupying the space between two adjacent winding assemblies, thus affecting the compactness of the layout structure of the two adjacent winding assemblies, thereby improving the structural compactness of the distribution of each winding assembly along the track. On the other hand, since the winding motors are arranged between the two winding arms of the same winding assembly, the winding motors occupy a certain space between the two winding arms, and the two winding arms of the same winding assembly will be affected when they are close to each other. In order to reduce the impact of the winding motors on the closeness of the two winding arms of the same winding assembly, this solution staggers the winding motors on the two winding arms of the same winding assembly in the direction perpendicular to the track. In this way, the two winding arms of the same winding assembly can be brought closer together, so that the film rolls with smaller widths can be wound between the two winding arms of the winding assembly, thus accommodating the winding of film rolls with smaller widths.

[0024] Specific Implementation Example 1, such as Figure 1 , Figure 2 As shown, a heavy-duty winding arm device for a slitting machine includes a base 1 and several winding assemblies 2. The base 1 is provided with horizontally distributed tracks 1.1. The winding assemblies 2 are sequentially distributed along the tracks 1.1.

[0025] The winding assembly 2 includes two winding arms 2.1 that slide along the track 1.1, a winding chuck 2.2 corresponding to each winding arm 2.1, and a winding drive mechanism 2.4 corresponding to each winding arm 2.1.

[0026] The take-up chuck 2.2 is rotatably mounted on the top of the take-up arm 2.1 via a drive shaft 2.3. The drive shafts 2.3 on the two take-up arms 2.1 of the same take-up assembly 2 are coaxially distributed. The two take-up chucks 2.2 of the same take-up assembly 2 are located between the two take-up arms 2.1. The drive shaft 2.3 on the same take-up arm 2.1 is coaxially distributed with the take-up chuck 2.2.

[0027] The winding drive mechanism 2.4 includes a winding motor 2.41 located at the bottom of the winding arm 2.1 and a belt drive mechanism 2.42 connecting the winding motor 2.41 and the drive shaft 2.3. The winding motor 2.41 of the same winding assembly 2 is located between the two winding arms 2.1. The winding motors 2.41 on the two winding arms 2.1 of the same winding assembly 2 are staggered in a direction perpendicular to the track 1.1.

[0028] The winding arm 2.1 of the heavy-duty winding arm device of the slitting machine in this embodiment adopts a dual-drive design. Each winding arm 2.1 of the winding assembly 2 is equipped with a winding motor 2.41 for driving the winding chuck 2.2 to rotate. In this way, during the winding process, the winding motors 2.41 of the two winding drive mechanisms 2.4 can drive the same winding film roll to rotate, providing double the winding driving force. It is especially suitable for winding film rolls with large diameter and large weight (the diameter of the winding film roll after slitting can reach 1.5 meters and the weight can reach 1-2 tons). In the later stage of winding the slitting material, as the diameter and weight of the film roll increase, it ensures that double the winding driving force is provided for winding, avoiding the problem of insufficient winding driving force, which affects the winding efficiency and winding quality.

[0029] Meanwhile, since the two take-up motors 2.41 of the same take-up assembly 2 are located between the two take-up arms 2.1, and the take-up motors 2.41 on the two take-up arms 2.1 of the same take-up assembly 2 are staggered in the direction perpendicular to the track 1.1, this avoids the problem of the take-up motors 2.41 being located outside the take-up arms 2.1 and occupying the space between two adjacent take-up assemblies 2, thus affecting the compactness of the layout structure of the two adjacent take-up assemblies 2, thereby improving the structural compactness of the distribution of each take-up assembly 2 along the track 1.1; on the other hand, since the take-up motors 2.41 are arranged between the two take-up arms 2.1 of the same take-up assembly 2, the take-up motors... 2.41 occupies a certain space between the two take-up arms 2.1. When the two take-up arms 2.1 of the same take-up assembly 2 are close to each other, they will be affected by the take-up motor 2.41. In order to reduce the influence of the take-up motor 2.41 on the two take-up arms 2.1 of the same take-up assembly 2 to get close to each other, this solution distributes the take-up motors 2.41 on the two take-up arms 2.1 of the same take-up assembly 2 in a staggered manner in the direction perpendicular to the track 1.1. In this way, the two take-up arms 2.1 of the same take-up assembly 2 can get closer together, so that the film roll with a smaller width can be wound between the two take-up arms 2.1 of the take-up assembly 2, in order to accommodate the winding of the film roll with a smaller width.

[0030] Specific embodiment two, such as Figure 1 , Figure 2 As shown, a heavy-duty take-up arm device for a slitting machine includes a base 1, a translation drive mechanism 4, and several take-up assemblies 2. The base 1 is provided with horizontally distributed tracks 1.1. The take-up assemblies 2 are sequentially distributed along the tracks 1.1.

[0031] The winding assembly 2 includes two winding arms 2.1 that slide along the track 1.1, a winding chuck 2.2 corresponding to each winding arm 2.1, and a winding drive mechanism 2.4 corresponding to each winding arm 2.1.

[0032] The translation drive mechanism 4 drives the take-up arm 2.1 to slide along the track 1.1. For example, the translation drive mechanism 4 can be an electric cylinder, a pneumatic cylinder, or a linear module. In this embodiment, the translation drive mechanism 4 includes a rack 4.1, a gear 4.2, and a shift motor 4.3. The rack 4.1 is fixed to the base 1 and parallel to the track 1.1. The rack 4.1 is fixed to the base 1 by bolts. The gear 4.2 corresponds one-to-one with the take-up arm 2.1 and is located at the bottom of the corresponding take-up arm 2.1. The gear 4.2 meshes with the rack 4.1. The shift motor 4.3 corresponds one-to-one with the take-up arm 2.1 and is fixed to the bottom of the take-up arm 2.1, driving the corresponding gear 4.2 to rotate. In this way, each take-up arm 2.1 can be driven to move along the track 1.1 by rotating the gear 4.2 through the corresponding shift motor 4.3, and the displacement of the take-up arm 2.1 can be precisely controlled by controlling the rotation angle of the shift motor 4.3.

[0033] The take-up chuck 2.2 is rotatably mounted on the top of the take-up arm 2.1 via a drive shaft 2.3. In this embodiment, the drive shaft 2.3 is rotatably mounted on the top of the take-up arm 2.1 via a bearing, and the drive shaft 2.3 is parallel to the track 1.1. The drive shafts 2.3 on the two take-up arms 2.1 of the same take-up assembly 2 are coaxially distributed. The two take-up chucks 2.2 of the same take-up assembly 2 are located between the two take-up arms 2.1. The drive shaft 2.3 on the same take-up arm 2.1 is coaxially distributed with the take-up chuck 2.2.

[0034] The winding drive mechanism 2.4 includes a winding motor 2.41 located at the bottom of the winding arm 2.1 and a belt drive mechanism 2.42 connecting the winding motor 2.41 and the drive shaft 2.3. The winding motor 2.41 of the same winding assembly 2 is located between the two winding arms 2.1. The winding motors 2.41 on the two winding arms 2.1 of the same winding assembly 2 are staggered in a direction perpendicular to the track 1.1.

[0035] The specific use of the heavy-duty take-up arm device of the slitting machine in this embodiment is as follows. Place the take-up mandrel 3 (which is a hollow structure with open ends at both ends of its inner hole) between the two take-up arms 2.1 of the take-up assembly 2; Bring the two take-up arms 2.1 of the take-up assembly 2 closer together, so that the take-up chucks 2.2 at the top of the two take-up arms 2.1 of the take-up assembly 2 are inserted into both ends of the take-up mandrel 3 and clamped to the take-up mandrel; Next, the winding motor 2.41 drives the winding chuck 2.2 to rotate, which in turn drives the winding mandrel 3 to rotate, thereby winding up the slit material to form a slit winding film roll.

[0036] The winding arm 2.1 of the heavy-duty winding arm device of the slitting machine in this embodiment adopts a dual-drive design. Each winding arm 2.1 of the winding assembly 2 is equipped with a winding motor 2.41 for driving the winding chuck 2.2 to rotate. In this way, during the winding process, the winding motors 2.41 of the two winding drive mechanisms 2.4 can drive the same winding film roll to rotate, providing double the winding driving force. It is especially suitable for winding film rolls with large diameter and large weight (the diameter of the winding film roll after slitting can reach 1.5 meters and the weight can reach 1-2 tons). In the later stage of winding the slitting material, as the diameter and weight of the film roll increase, it ensures that double the winding driving force is provided for winding, avoiding the problem of insufficient winding driving force, which affects the winding efficiency and winding quality.

[0037] Meanwhile, since the two take-up motors 2.41 of the same take-up assembly 2 are located between the two take-up arms 2.1, and the take-up motors 2.41 on the two take-up arms 2.1 of the same take-up assembly 2 are staggered in the direction perpendicular to the track 1.1, this avoids the problem of the take-up motors 2.41 being located outside the take-up arms 2.1 and occupying the space between two adjacent take-up assemblies 2, thus affecting the compactness of the layout structure of the two adjacent take-up assemblies 2, thereby improving the structural compactness of the distribution of each take-up assembly 2 along the track 1.1; on the other hand, since the take-up motors 2.41 are arranged between the two take-up arms 2.1 of the same take-up assembly 2, the take-up motors... 2.41 occupies a certain space between the two take-up arms 2.1. When the two take-up arms 2.1 of the same take-up assembly 2 are close to each other, they will be affected by the take-up motor 2.41. In order to reduce the influence of the take-up motor 2.41 on the two take-up arms 2.1 of the same take-up assembly 2 to get close to each other, this solution distributes the take-up motors 2.41 on the two take-up arms 2.1 of the same take-up assembly 2 in a staggered manner in the direction perpendicular to the track 1.1. In this way, the two take-up arms 2.1 of the same take-up assembly 2 can get closer together, so that the film roll with a smaller width can be wound between the two take-up arms 2.1 of the take-up assembly 2, in order to accommodate the winding of the film roll with a smaller width.

[0038] The take-up motors 2.41 on the two take-up arms 2.1 of the same take-up assembly 2 are located at the same height, and the take-up motors 2.41 on the two take-up arms 2.1 of the same take-up assembly 2 are staggered horizontally upwards perpendicular to the track 1.1. The take-up motors 2.41 on the two take-up arms 2.1 of the same take-up assembly 2 can be arranged at the bottom of the take-up arm 2.1, thereby lowering the overall center of gravity of the take-up arm 2.1 and improving the movement stability of the take-up arm 2.1.

[0039] Furthermore, such as Figure 1 , Figure 2 As shown, the take-up arm 2.1 has a receiving cavity 2.8. The belt drive mechanism 2.42 is located in the receiving cavity 2.8 of the corresponding take-up arm 2.1. In this way, the structural compactness of the take-up assembly 2 itself can be effectively improved. At the same time, it can also avoid the belt drive mechanism 2.42 occupying the space outside the take-up arm 2.1, thus avoiding affecting the compactness of the layout structure of the two adjacent take-up assemblies 2.

[0040] In this embodiment, the belt drive mechanism 2.42 is a synchronous belt drive mechanism, which also includes a tension pulley 2.43, which is also located in the receiving cavity of the corresponding winding arm 2.1.

[0041] Furthermore, such as Figure 2As shown, a motor baffle 2.5 is also provided on the winding arm 2.1, and the motor baffle is fixed on the corresponding winding arm 2.1. The winding motor 2.41 is located below the motor baffle, and the motor baffle is close to the winding motor 2.41. In this way, the winding motor 2.41 can be protected on the one hand, and the collision between the film roll and the winding motor 2.41 can be avoided on the other hand.

[0042] Furthermore, such as Figure 2 As shown, the width of the winding arm 2.1 gradually increases from top to bottom. This improves the structural stability of the winding arm 2.1 and lowers its overall center of gravity, which is beneficial for improving its movement stability.

[0043] In this specific embodiment, the remaining structure is the same as in specific embodiment one or specific embodiment two, except that... like Figure 3 , Figure 4 As shown, a heavy-duty take-up arm device for a slitting machine also includes a plug-in shaft 2.7.

[0044] The drive shafts 2.3 on the winding arms 2.1 of each winding assembly 2 are coaxially distributed. Each drive shaft 2.3 is provided with a insertion hole 2.6 that mates with the insertion shaft 2.7. The openings of the insertion holes 2.6 on the drive shafts 2.3 of the two winding arms 2.1 of the same winding assembly 2 are distributed facing away from each other.

[0045] When two adjacent take-up assemblies 2 approach each other, the insertion shaft 2.7 can be simultaneously inserted into the insertion holes 2.6 of two adjacent take-up arms 2.1 of the two take-up assemblies 2. In this embodiment, "when two adjacent take-up assemblies 2 approach each other, the insertion shaft 2.7 can be simultaneously inserted into the insertion holes 2.6 of two adjacent take-up arms 2.1 of the two take-up assemblies 2" means that when two adjacent take-up assemblies 2 approach each other, one end of the insertion shaft 2.7 can be inserted into the insertion hole 2.6 of the take-up arm 2.1 of one of the take-up assemblies 2, and the other end of the insertion shaft 2.7 can be inserted into the insertion hole 2.6 of the take-up arm 2.1 of the other adjacent take-up assembly 2.

[0046] After the connector shaft 2.7 is inserted into the connector hole 2.6, the connector shaft 2.7 and the connector hole 2.6 shall not rotate relative to each other.

[0047] In one example, the inner wall of the insertion hole 2.6 is provided with a keyway, and the insertion shaft 2.7 is provided with a corresponding protruding key; for example, the insertion hole 2.6 is a spline hole, and the corresponding insertion shaft 2.7 is a spline shaft. In this way, after the insertion shaft 2.7 is inserted into the insertion hole 2.6, the insertion shaft 2.7 and the insertion hole 2.6 cannot rotate relative to each other, thereby ensuring that the drive shafts 2.3 of the two adjacent winding arms 2.1 in the two adjacent winding assemblies 2 can stably transmit power through the insertion shaft 2.7.

[0048] In another example, the cross-section of the insertion hole 2.6 is a regular polygon, and the corresponding cross-section of the insertion shaft 2.7 is also a regular polygon. Thus, after the insertion shaft 2.7 is inserted into the insertion hole 2.6, there is no relative rotation between the insertion shaft 2.7 and the insertion hole 2.6, ensuring that the drive shafts 2.3 of the two adjacent winding arms 2.1 in the two adjacent winding assemblies 2 can stably transmit power through the insertion shaft 2.7.

[0049] The heavy-duty take-up arm device of the slitting machine in this embodiment can provide a greater take-up driving force for the film roll between the two take-up arms 2.1 of the same take-up assembly 2, so as to accommodate the take-up of film rolls with larger diameters and masses. Specifically, When the winding motors 2.41 on the two winding arms 2.1 of a winding assembly 2 (hereinafter referred to as the working winding assembly 2) that is in the winding operation still experience insufficient winding driving force while driving the winding film roll to rotate, a winding assembly 2 adjacent to the working winding assembly 2 (this winding assembly 2 is not in the winding operation, referred to as the non-working winding assembly 2) can be brought close to the working winding assembly 2, and the insertion shaft 2.7 can be inserted into the insertion holes 2.6 of the two adjacent winding arms 2.1 of the two winding assemblies 2. In this way, the winding motor 2.41 on one winding arm 2.1 of the adjacent non-working winding assembly 2 can also provide winding driving force for the working winding assembly 2, that is, it can provide three times the winding driving force for the winding of the working winding assembly 2 (the three winding motors 2.41 provide winding driving force at the same time), so as to adapt to the winding of film rolls with larger diameter and mass. If three times the winding drive force is still insufficient, the two non-working winding assemblies 2 adjacent to the working winding assembly 2 can be brought closer to the working winding assembly 2. One insertion shaft 2.7 is inserted into the insertion holes 2.6 of the two adjacent winding arms 2.1 of the working winding assembly 2 and the left non-working winding assembly 2, and another insertion shaft 2.7 is inserted into the insertion holes 2.6 of the two adjacent winding arms 2.1 of the working winding assembly 2 and the right non-working winding assembly 2. In this way, the winding motor 2.41 on each of the two adjacent left and right non-working winding assemblies 2 can also provide winding drive force for the working winding assembly 2, that is, it can provide four times the winding drive force for the winding of the working winding assembly 2 (four winding motors 2.41 provide winding drive force at the same time), so as to adapt to the winding of film rolls with larger diameters and weights.

[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
