[0049] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0050] The following combination Figures 1 to 5 , the automatic film tearing and recycling device for the outer coating of the packaging material roll assembly provided by the embodiment of the present invention is described in detail through specific embodiments and application scenarios.

[0051] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides an automatic film tearing and recycling device 2 for the outer film of a packaging material roll assembly, comprising: an outer film tearing device 21 and an outer film recycling device 22.

[0052] The outer film tearing device 21 includes: a mounting frame 211, a film cutting assembly 212 and a film stripping assembly 213; the mounting frame 211 is arranged on the upper side of the packaging material conveyor line, and the packaging material conveyor line is used to convey the packaging material roll assembly 300; the film cutting assembly 212 and the film stripping assembly 213 are respectively arranged on the mounting frame 211.

[0053] The film cutting assembly 212 includes a moving mechanism 2121 and a film cutting tool 2122. The moving mechanism 2121 and the film cutting tool 2122 are connected. The moving mechanism 2121 is used to drive the film cutting tool 2122 to move horizontally and vertically relative to the packaging material roll assembly 300 to cut the outer film on the top and side surfaces of the packaging material roll assembly 300 in sequence; the film stripping assembly 213 is used to be connected to the outer film to drive the outer film to be peeled off from the surface of the packaging material roll assembly 300.

[0054] The outer film recovery device 22 is used to recover the outer film peeled off from the surface of the packaging material roll assembly 300 .

[0055] It is understood that on the packaging material conveyor line, several packaging material rolls are stacked vertically, each coated with an outer film, to form the packaging material roll assembly 300 shown in this embodiment. The central axis of the packaging material roll assembly 300 is arranged vertically. The outer film tearing device 21 and the outer film recovery device 22 are both located at the same station, and the packaging material roll assembly 300 performs the film cutting, stripping, and recovery operations in this device.

[0056] Since the number of packaging material rolls in the packaging material roll assembly 300 is not fixed, the heights of the packaging material roll assemblies 300 are inconsistent. Therefore, when the film cutting tool 2122 performs film cutting operations on different packaging material roll assemblies 300, the height of the film cutting tool 2122 needs to be adjusted. When the film cutting tool 2122 cuts the side of the packaging material roll assembly 300, the height of the film cutting tool 2122 also needs to be adjusted. At the same time, when the film cutting tool 2122 cuts the top surface of the packaging material roll assembly 300, the horizontal position of the film cutting tool 2122 needs to be adjusted, and thus the position of the film cutting tool 2122 also needs to be adjusted. The moving mechanism 2121 can drive the film cutting tool 2122 to move in the horizontal and vertical directions to adjust the spatial position of the film cutting tool 2122. In this embodiment, the order of movement of the film cutting tool 2122 in the horizontal and vertical directions is not limited. The film cutting tool 2122 can move in the horizontal direction first and then in the vertical direction, or it can move in the vertical direction first and then in the horizontal direction.

[0057] Specifically, the moving component may be a robotic arm or a structure composed of two linear modules.

[0058] In actual application, the packaging material roll assembly 300 is transported and placed on the packaging material conveyor line, and is transported to the mounting rack 211 by the packaging material conveyor line. The moving mechanism 2121 drives the film cutting tool 2122 to move in the horizontal and vertical directions in turn, cutting the top and side surfaces of the outer film of the packaging material roll assembly 300 in turn. The film stripping assembly 213 peels off the cut coating from the surface of the packaging material roll assembly 300, and the outer film recovery device 22 recovers the peeled outer film.

[0059] The present invention provides an automatic film tearing and recycling device 2 for the outer coating of a packaging material roll assembly. An outer coating film tearing device 21 and an outer coating film recycling device 22 are provided, and a mounting frame 211, a film cutting assembly 212 and a film stripping assembly 213 are provided in the outer coating film tearing device 21. The moving mechanism 2121 of the film cutting assembly 212 drives the film cutting tool 2122 to cut the top surface and the side surface of the outer coating film in sequence, so that the packaging material roll assembly 300 can automatically realize the cutting, stripping and recycling of the outer coating of the packaging material roll assembly 300 in the device without manual intervention, avoiding dependence on manual operation, and being conducive to realizing the automation of cutting, stripping and recycling of the outer coating, and improving the efficiency and quality of cutting, stripping and recycling of the outer coating, ensuring the reliability of the entire film tearing, stripping and recycling operation process.

[0060] In some embodiments, as Figure 3 As shown, the moving mechanism 2121 of this embodiment includes a lifting driving component 21211 , a translation driving component 21212 and a transfer arm 21213 .

[0061] The lifting driving member 21211 is disposed on the mounting frame 211 , and the lifting driving member 21211 is connected to the translation driving member 21212 to drive the translation driving member 21212 to move in the vertical direction.

[0062] The translation driving member 21212 is connected to the first end of the transfer arm 21213 , and the second end of the transfer arm 21213 is connected to the film cutting tool 2122 ; the translation driving member 21212 is used to drive the transfer arm 21213 to move horizontally along the radial direction of the packaging material roll assembly 300 .

[0063] It can be understood that when the lifting drive component 21211 drives the translation drive component 21212 to move in the vertical direction, the translation drive component 21212 drives the transfer arm 21213 to move in the vertical direction, which can not only adjust the height of the transfer arm 21213 according to the packaging material roll assembly 300 with different heights, but also enable the transfer arm 21213 to drive the film cutting tool 2122 to move up and down to cut the covering film on the side of the packaging material roll assembly 300; when the translation drive component 21212 drives the transfer arm 21213 to move horizontally along the radial direction of the packaging material roll assembly 300, the transfer arm 21213 can drive the film cutting tool 2122 to move horizontally along the top surface of the packaging material roll assembly 300 to cut the covering film on the top surface of the packaging material roll assembly 300.

[0064] Among them, the lifting drive component 21211 can be any one of an electric push rod, a linear motor and a cylinder, and the translation drive component 21212 can also be any one of an electric push rod, a linear motor and a cylinder.

[0065] Furthermore, the adapter arm 21213 of this embodiment is connected to the film cutting tool 2122 through an adapter frame. The adapter frame includes a fixed adapter frame, a floating adapter frame and an elastic component. The fixed adapter frame is arranged on the adapter arm 21213, the floating adapter frame is movably arranged on the fixed adapter frame in the vertical direction, the elastic component is arranged between the fixed adapter frame and the floating adapter frame, and the film cutting tool 2122 is arranged on the floating adapter frame.

[0066] The floating adapter frame can move vertically, and the elastic member can create an elastic force between the fixed adapter frame and the floating adapter frame, so that when the film cutting knife 2122 cuts the outer film of the packaging material roll assembly 300, the film cutting knife 2122 and the outer film always maintain flexible contact, ensuring the cutting effect. The film cutting knife 2122 does not exert excessive cutting force on the outer film, thus avoiding damage to the packaging material roll assembly 300 caused by the rigid contact between the film cutting knife 2122 and the packaging material roll assembly 300. The elastic member can be a spring.

[0067] In some embodiments, as Figure 3 As shown, the transfer arm 21213 of this embodiment is arranged horizontally, and the second end of the transfer arm 21213 is configured to extend toward the central axis of the packaging material roll assembly 300.

[0068] It can be understood that since the top surface of the outer film of the packaging material roll assembly 300 is extended in the horizontal direction, the second end of the adapter arm 21213 of this embodiment extends toward the central axis of the packaging material roll assembly 300, which can ensure that the film cutting tool 2122 is located directly above the central axis of the packaging material roll assembly 300, so that when the film cutting tool 2122 cuts the outer film, the adapter arm 21213 drives the film cutting assembly 212 to cut the outer film in the horizontal direction, and the cutting path passes through the center of the top surface of the packaging material roll assembly 300, which makes the incision of the film cutting tool 2122 on the top surface of the outer film the longest, so that the cutting efficiency of the top surface of the outer film is higher.

[0069] In some embodiments, as Figure 3 As shown, at least one of the lifting drive component 21211 and the translation drive component 21212 of this embodiment is configured as a screw drive component.

[0070] It is understandable that the screw drive component is a mechanical device used for linear displacement adjustment, which is usually composed of components such as a screw, a nut and a supporting structure.

[0071] In this embodiment, at least one of the lifting drive component 21211 and the translation drive component 21212 is set as a screw drive component. By rotating the screw, the nut moves on the thread on the screw, thereby realizing the adjustment of linear displacement, so that the lifting drive component 21211 or the translation drive component 21212 has high transmission efficiency, high positioning accuracy and large load-bearing capacity.

[0072] In some embodiments, as Figure 3 As shown, the film cutting tool 2122 of this embodiment is vertically arranged and is equipped with a first cutting edge and a second cutting edge.

[0073] The first cutting edge is connected to the second cutting edge. The first cutting edge is extended in a vertical direction, and the second cutting edge is extended in a horizontal direction.

[0074] It can be understood that in this embodiment, the first cutting edge is extended in the vertical direction and the second cutting edge is extended in the horizontal direction, so that the film cutting tool 2122 can cut the outer film along the top and side surfaces of the packaging material roll assembly 300. The cutting of each surface of the outer film can ensure that the outer film of the packaging material roll assembly 300 is divided into multiple parts after multiple cuttings, which is convenient for subsequent film stripping operations.

[0075] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 As shown, the mounting frame 211 of this embodiment is a gantry frame, and the film cutting assembly 212 and the film stripping assembly 213 are relatively separately arranged on two vertical beams of the gantry frame.

[0076] It can be understood that in this embodiment, the outer film is cut on one side of the packaging material roll assembly 300 and the outer film is peeled off on the other side. The film cutting assembly 212 and the film peeling assembly 213 will not interfere with each other, and the outer film is peeled off after cutting. The structure of the entire device is compact, which is conducive to improving the efficiency of film tearing.

[0077] This embodiment sets the mounting frame 211 as a gantry frame, which has a stable structure and strong bearing capacity, and can realize the relative arrangement of the film cutting assembly 212 and the film stripping assembly 213, which is conducive to the scientific planning and layout of the outer film tearing device 21.

[0078] In some embodiments, as Figure 1 and Figure 2 As shown, the film stripping assembly 213 of this embodiment includes a first film stripping claw 2131 and a second film stripping claw 2132 .

[0079] The first end of the first film stripping claw 2131 and the first end of the second film stripping claw 2132 are close to each other and are both rotatably disposed on the mounting frame 211 ; the film stripping assembly 213 has a first film stripping state and a second film stripping state.

[0080] When the film stripping assembly 213 is in the first film stripping state, the second end of the first film stripping claw 2131 and the second end of the second film stripping claw 2132 are clamped on opposite sides of the peripheral wall of the packaging material roll assembly 300 and connected to the outer film.

[0081] When the film stripping assembly 213 is in the second film stripping state, the second end of the first film stripping claw 2131 and the second end of the second film stripping claw 2132 are away from the peripheral wall of the packaging material roll assembly 300 to peel the outer film from the surface of the packaging material roll assembly 300.

[0082] It is understandable that the first film stripping claw 2131 and the second film stripping claw 2132 can be connected to the outer film by rotating relative to the mounting frame 211 and peel the outer film from the surface of the packaging material roll assembly 300.

[0083] When the film stripping assembly 213 is in the first film stripping state, the covering film can be adsorbed onto the first and second film stripping claws 2131 and 2132 by using an adsorption assembly, or the covering film can be clamped onto the first and second film stripping claws 2131 and 2132 by using a clamping assembly.

[0084] This embodiment provides a first film peeling claw 2131 and a second film peeling claw 2132 in the film peeling assembly 213, and through the rotation of the first film peeling claw 2131 and the second film peeling claw 2132 around the mounting frame 211, it can achieve connection with the outer film when the first film peeling claw 2131 and the second film peeling claw 2132 are clamped on the peripheral wall of the packaging material roll assembly 300, and can also peel off the outer film as the first film peeling claw 2131 and the second film peeling claw 2132 move away from the packaging material roll assembly 300. The structure is compact and the film peeling efficiency is high.

[0085] In some embodiments, as Figure 1 and Figure 2 As shown, the first film stripping claw 2131 and the second film stripping claw 2132 of this embodiment have the same structure, and both include: a driving member 21311 , a claw body 21312 and an adsorption member 21313 .

[0086] The driving member 21311 is disposed on the mounting frame 211 , a first end of the claw body 21312 is rotatably disposed on the mounting frame 211 , and the adsorption member 21313 is disposed on a second end of the claw body 21312 .

[0087] The driving member 21311 and the claw body 21312 are connected by power coupling to drive the claw body 21312 to swing relative to the mounting frame 211, and the adsorption member 21313 is used to be adsorbed on the surface of the outer film.

[0088] It can be understood that when the first film stripping claw 2131 and the second film stripping claw 2132 are clamped on the peripheral wall of the packaging material roll assembly 300, the adsorption member 21313 adsorbs the outer film on the first film stripping claw 2131 and the second film stripping claw 2132. Since the outer film is light in weight and thin in thickness, the adsorption member 21313 is used to adsorb the outer film, which can better connect the second ends of the first film stripping claw 2131 and the second film stripping claw 2132 with the outer film, and the outer film is not easy to fall off from the first film stripping claw 2131 and the second film stripping claw 2132.

[0089] The driving member 21311 of this embodiment drives the claw body 21312 to swing relative to the mounting frame 211. When the outer film is adsorbed on the claw body 21312, the claw body 21312 can peel off the outer film from the surface of the packaging material roll assembly 300, thereby achieving the effect of quickly and conveniently peeling off the outer film.

[0090] Among them, the driving component 21311 can be an electric motor or a hydraulic motor; the adsorption component 21313 can be a negative pressure suction nozzle device.

[0091] In some embodiments, as Figure 2 As shown, in this embodiment, a plurality of adsorption members 21313 are provided, and the plurality of adsorption members 21313 are arranged in sequence along the axial direction of the packaging material roll assembly 300 .

[0092] It is understandable that multiple adsorption components 21313 can simultaneously adsorb the outer film after cutting, increasing the contact points for adsorption of the outer film, and when the side of the outer film is cut vertically by the film cutting tool 2122, a vertical cutting seam is obtained. The adsorption components 21313 of this embodiment are arranged along the axial direction of the packaging material roll assembly 300, which is the same as the arrangement direction of the cutting seam, and is more conducive to peeling the outer film from the surface of the packaging material roll assembly 300, thereby improving the adsorption efficiency of the outer film and having a good traction effect on the outer film.

[0093] In some embodiments, as Figure 2 As shown, the mounting frame 211 of this embodiment is provided with a film penetration opening 2111 , and the film penetration opening 2111 is located between the first end of the first film stripping claw 2131 and the first end of the second film stripping claw 2132 .

[0094] The film penetration port 2111 is used for the peeled outer film to penetrate and reach the outer film recovery device 22 of the packaging material roll assembly.

[0095] It can be understood that since an outer film recovery device 22 is provided on the side of the mounting frame 211 close to the film stripping assembly 213, the outer film stripped by the first film stripping claw 2131 and the second film stripping claw 2132 can pass through the mounting frame 211 through the film penetration port 2111, and the traction and pulling applied to the outer film by the outer film recovery device 22 can also be operated through the film penetration port 2111.

[0096] In this embodiment, a film penetration port 2111 is provided so that a penetration channel for the coating film is formed on the side of the mounting frame 211. Through the penetration channel, the coating film can be peeled off on the packaging material roll conveyor line and enter the outer film recovery device 22 provided on the other side of the mounting frame 211. The penetration channel connects the cutting, peeling and recovery stations of the packaging material roll assembly 300, making the structural setting more compact, avoiding manual operation, and having a high level of automation.

[0097] In some embodiments, as Figure 4 and Figure 5 As shown, the outer film recovery device 22 of this embodiment includes: a film stripping component 221, a conveying component 222 and a recovery component 223.

[0098] The demolding member 221 includes a moving part 2211 and a pulling member 2212 . The moving part 2211 and the pulling member 2212 are connected to drive the pulling member 2212 to move between the first target position and the second target position.

[0099] A first end of the conveying member 222 is disposed opposite to the packaging material roll assembly 300 , and a second end of the conveying member 222 is connected to the recovery member 223 .

[0100] When the pulling member 2212 is at the first target position, the pulling member 2212 is located at the first end of the conveying member 222 and is connected to the outer film on the surface of the packaging material roll assembly 300 .

[0101] When the pulling member 2212 is at the second target position, the pulling member 2212 is close to the second end of the conveying member 222 and releases the outer film on the conveying member 222 .

[0102] It can be understood that the moving component 2211 can drive the traction member 2212 to move in a straight line direction so that the traction member 2212 can be connected to the outer film and pull the outer film from the first target position to the second target position, that is, the outer film is pulled from the first end of the conveying member 222 to near the second end. At the position where the conveying member 222 is near the second end, the traction member 2212 no longer applies traction force to the outer film, so that the outer film is placed on the conveying member 222.

[0103] The conveying member 222 may be a belt conveyor assembly or a chain plate conveyor; the traction member 2212 may be a suction cup for adsorbing and connecting the outer film; the traction member 2212 may also be a clamping assembly for clamping and connecting the outer film;

[0104] The recycling member 223 may be a recycling trough structure to receive and store the outer film transported by the transport member 222, so as to avoid the cut outer film being scattered in the factory, thereby keeping the operating site clean and tidy, and also facilitating the centralized transportation of discarded outer films.

[0105] This embodiment provides a film stripping component 221, a conveying component 222 and a recovery component 223, and provides a moving component 2211 and a traction component 2212 in the film stripping component, so that the traction component 2212, driven by the moving component 2211, pulls the outer film of the packaging material roll assembly 300 from the first end of the conveying component 222 to near the second end, and releases it on the conveying component 222, so that the outer film is conveyed to the recovery component 223, thereby realizing full automation of the film stripping, conveying and recovery of the outer film, and improving the recovery efficiency of the outer film.

[0106] In some embodiments, as Figure 4 and Figure 5 As shown, the traction member 2212 of this embodiment includes a suction nozzle member; the suction nozzle member is located on the upper side of the conveying member 222, and the moving part 2211 is connected to the suction nozzle member to drive the suction nozzle member to move back and forth along the extension direction of the conveying member 222.

[0107] It can be understood that the suction nozzle component is connected to the negative pressure device, and can adsorb the outer film and pull the outer film from the first end of the conveying component 222 to near the second end. Since the outer film has the characteristics of light weight and thin thickness, the suction nozzle component is used to pull the outer film, which can ensure good adsorption effect, convenient operation, high adsorption efficiency, and can quickly achieve adsorption and release of the outer film by controlling the negative pressure device.

[0108] Specifically, the moving component 2211 is a linear motor module, and the slide of the linear motor module is connected to the suction nozzle component; the linear motor module is arranged on one side of the conveying component 222 and extends along the conveying direction of the conveying component 222.

[0109] The linear motor module has a fast response speed and high positioning accuracy, and can ensure the stability and reliability of the reciprocating movement of the suction nozzle component along the extension direction of the conveying component 222.

[0110] In some embodiments, as Figure 4 and Figure 5 As shown, in this embodiment, a plurality of suction nozzle components are provided, and the suction nozzle components are sequentially arranged side by side along the axial direction of the packaging material roll assembly 300 .

[0111] It is understandable that the multiple suction nozzle components can simultaneously adsorb the cut outer film, which increases the contact points for adsorption of the outer film, thereby improving the adsorption efficiency of the outer film and achieving a good traction effect on the outer film.

[0112] In some embodiments, as Figure 4 and Figure 5 As shown, the film stripping component 221 of this embodiment further includes a conveying roller set 2213 .

[0113] The conveying roller set 2213 is disposed at the first end of the conveying member 222 . The conveying roller set 2213 has a clamping gap for the outer film to pass through. The conveying roller set 2213 is used to drive the outer film to move toward the traction direction of the traction member 2212 .

[0114] When the traction member 2212 is at the first target position, at least a portion of the traction member 2212 passes through the clamping gap of the conveying roller set 2213 and is connected to the outer film.

[0115] It can be understood that when the traction member 2212 is connected to the outer film and pulls the outer film, the conveying roller group 2213 provides driving force for the outer film, so that the outer film moves from the first end of the conveying member 222 toward the second end. When the outer film extends into the clamping gap and is pulled forward by the traction member 2212, the conveying roller group 2213 provides continuous conveying power for the outer film, so that the outer film passes through the clamping gap and is conveyed to the conveying member 222.

[0116] The clamping gap is extended in the vertical direction, and the covering film cut in the vertical direction can more easily pass through the vertical clamping gap, thereby being more conducive to the traction drive of the covering film.

[0117] In this embodiment, a conveying roller group 2213 is provided so that when the outer film is pulled by the traction member 2212, a driving force is provided to make the outer film extend into the clamping gap and pull the outer film onto the conveying member 222, so as to ensure that the entire outer film enters the conveying member 222, thereby realizing the automatic transfer of the outer film from the outer film tearing device 21 to the outer film recovery device 22.

[0118] In some embodiments, as Figure 4 and Figure 5 As shown, the conveying roller set 2213 of this embodiment includes a first vertical driving roller 22131 and a second vertical driving roller 22132 , and the first vertical driving roller 22131 and the second vertical driving roller 22132 are configured to rotate in opposite directions.

[0119] It can be understood that after the outer film is cut and peeled off in the film tearing device, it reaches one side of the conveying roller group 2213 through the film penetration port 2111 on the mounting frame 211, and the outer film is in a vertically peeled state. The clamping gap between the first vertical driving roller 22131 and the second vertical driving roller 22132 can accommodate the outer film to pass through, and the first vertical driving roller 22131 and the second vertical driving roller 22132 can provide continuous power to promote the vertical conveying of the outer film.

[0120] The first vertical drive roller 22131 and the second vertical drive roller 22132 of this embodiment rotate in opposite directions, which can ensure that the outer coating film entering the clamping gap can be driven by driving forces in the same direction on the left and right sides, so that the outer coating film can move more efficiently along the traction direction of the traction member 2212, so that the outer coating film can be quickly transported to the upper side of the conveying member 222.

[0121] In some embodiments, as Figure 4 and Figure 5 As shown, the outer film recovery device 22 of this embodiment further includes a pressing component 224 .

[0122] The pressing member 224 is provided on the upper side of the conveying member 222 and has a first pressing height and a second pressing height relative to the conveying member 222 .

[0123] When the pressing member 224 is at the first pressing height, an escape space is formed between the pressing member 224 and the conveying member 222 , and the escape space is used for the traction member 2212 to pass through.

[0124] When the pressing member 224 is at the second pressing height, a pressing space is formed between the pressing member 224 and the conveying member 222 , and the pressing space is used to press the outer film.

[0125] It is understandable that when the traction member 2212 is in the first target position and adsorbs the outer film, the pressing member 224 is higher than the height of the traction member 2212, and the avoidance space can allow the traction member 2212 to pass through to avoid interference between the pressing member 224 and the traction member 2212; when the traction member 2212 pulls the outer film, the outer film extends into the clamping gap, and then moves along with the traction member 2212 with the assistance of the conveying roller group 2213. When the traction member 2212 returns to the second target position, the pressing member 224 descends vertically to press the outer film on the conveying member 222. The pressing member 224 can press the outer film in the pressing space to facilitate the outer film to be close to the conveying surface of the conveying member 222.

[0126] In this embodiment, a pressing component 224 is provided so that the outer coating film enters the upper side of the conveyor line after being driven by the conveying roller group 2213 and pulled by the traction member 2212, and is pressed on the conveyor line by the pressing component 224. The outer coating film with a fluffy and disordered appearance can be attached to the conveyor line in a regular shape after being squeezed by the pressing component 224, which is more conducive to the transportation of the outer coating film and improves the transportation efficiency of the outer coating film.

[0127] In some embodiments, as Figure 4 and Figure 5 As shown, the pressing member 224 of this embodiment includes: a pressing fixing frame 2241 , a pressing plate 2242 and a vertical moving component 2243 .

[0128] The pressing and fixing frame 2241 is disposed on the upper side of the conveying member 222 , and the vertical moving component 2243 is disposed on the pressing and fixing frame 2241 and connected to the pressing plate 2242 .

[0129] The vertical moving component 2243 is used to control the lifting and lowering of the pressing plate 2242 to press the outer film.

[0130] It is understandable that the pressing plate 2242 can be set as a square plate, which is arranged opposite to the conveying surface of the conveyor line. The vertical moving part 2243 drives the pressing plate 2242 to move in the vertical direction to squeeze the outer film to achieve automatic pressing of the outer film, thereby improving the pressing efficiency of the outer film.

[0131] The vertical moving component 2243 can be any one of an electric push rod, a linear motor and a cylinder.

[0132] In some embodiments, as Figure 4 and Figure 5As shown, the outer film recovery device 22 of this embodiment further includes: a limiting component 225.

[0133] The limiting assembly 225 is arranged on the upper side of the conveying member 222 and is equipped with a first limiting plate 2251 and a second limiting plate 2252; the first limiting plate 2251 and the second limiting plate 2252 are spaced from each other and arranged side by side; the first limiting plate 2251 and the second limiting plate 2252 are used to accommodate the outer film.

[0134] In the vertical direction, the projection of the pressing member 224 is located between the projection of the first limiting plate 2251 and the projection of the second limiting plate 2252 .

[0135] It is understandable that when the pressing member 224 presses the outer coating, the first limiting plate 2251 and the second limiting plate 2252 are used to stop both sides of the outer coating to prevent the outer coating from being squeezed out of the conveying member 222 when the pressing force is too large. Under the guidance of the first limiting plate 2251 and the second limiting plate 2252, the outer coating can be directionally extruded along the space between the first limiting plate 2251 and the second limiting plate 2252, ensuring that the limiting component 225 assists the pressing member 224 to extrude the outer coating into a regular shape, which is beneficial to the conveying of the outer coating.

[0136] In some embodiments, as Figure 4 As shown, in this embodiment, the first limiting plate 2251 and the second limiting plate 2252 are provided with an avoidance opening 22511 .

[0137] The avoidance opening 22511 is used to avoid the traction member 2212 , so that the traction member 2212 can pass through the first limiting plate 2251 and the second limiting plate 2252 in sequence under the drive of the moving component 2211 .

[0138] It is understandable that when the traction member 2212 moves between the first target position and the second target position under the drive of the moving part 2211, the traction member 2212 needs to pass through the first limit plate 2251 and the second limit plate 2252. The avoidance opening 22511 enables the traction member 2212 to pass through without being blocked by the first limit plate 2251 and the second limit plate 2252, thereby ensuring the reliability of the movement of the traction member 2212.

[0139] In some embodiments, as Figure 4 and Figure 5 As shown, the conveying component 222 of this embodiment includes a belt conveyor 2221 , and both sides of the belt conveyor 2221 are provided with limiting baffles 2222 , and the limiting baffles 2222 are extended along the conveying direction of the belt conveyor 2221 .

[0140] It can be understood that the belt conveyor 2221 of this embodiment can efficiently and reliably transport the outer coating film, and the limit baffles 2222 on both sides of the belt conveyor 2221 can block and limit the transported outer coating film to prevent the outer coating film from sliding from the belt conveyor 2221 to the bottom surface, thereby ensuring the reliability of the outer coating film transportation.

[0141] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
