Description

Technical Field

[0001] The present invention belongs to the technical field of master roll packaging equipment, and particularly relates to a master roll paper wrapping and sealing mechanism and a master roll packaging production line. Background Art

[0002] Before the semi-finished tape master roll is stacked and stored, it needs to be packaged to prevent the master roll body from being contaminated by the outside world. Specifically, the packaging layer includes a paper layer and a film layer. Specifically, after the paper layer is wound around the outer side wall of the master roll body, it is sealed and locked with a sealing tape, and then the plastic film is wrapped around the paper layer, thereby completing the packaging process of the tape master roll.

[0003] In the prior art, the paper layer needs to be completed by a paper winding machine. The paper winding machine includes a paper material conveying mechanism and a rotary driving mechanism. After the paper material conveying mechanism conveys the paper material to the tape master roll, the rotary driving mechanism drives the master roll to rotate, so that the paper material is wrapped around the outer side wall of the master roll, and manual operation is used to seal the adhesive on the paper roll.

[0004] It is true that the manual sealing method, on the one hand, adds labor positions, resulting in an increase in the production cost of the enterprise. On the other hand, the manual operation efficiency is low, which affects the automation process, reduces the material transfer efficiency, and leads to a decrease in the overall master roll packaging production efficiency, which is not conducive to the development of the enterprise.

[0005] The paper roll is generally sealed with a sealing tape, and the sealing tape is a kind of single-sided adhesive. If a bionic adhesive operation is carried out by an automatic roller or a clamping manipulator, the adhesive surface of the tape is easily adhered to the rolling surface of the roller or the clamping end of the clamping manipulator. And the non-adhesive surface of the tape is in a smooth state. If a clamping manipulator is used for clamping, the clamping difficulty is relatively large; if a roller structure is selected, the sealing tape needs to be rewound onto the corresponding roller. On the one hand, the adhesiveness of the adhesive surface decreases. On the other hand, the rewinding prolongs the packaging time, instead reducing the packaging production efficiency, which is not worth the candle.

[0006] Therefore, the traditional master roll packaging equipment has always been unable to achieve automatic sealing after paper winding, resulting in the production efficiency not being effectively improved, and there is an urgent need for improvement. Summary of the Invention

[0007] The purpose of the present invention is to provide a master roll paper wrapping and sealing mechanism and a master roll packaging production line, aiming to solve the technical problem that in the sealing process after the master roll is wrapped with paper in the prior art, due to the special nature of the tape material, the existing automatic feeding equipment cannot effectively clamp and convey the tape, the automatic sealing process is blocked, manual sealing is required, and the master roll packaging efficiency cannot be improved.

[0008] To achieve the above object, an adhesive sealing mechanism for a master roll wrapping paper provided by an embodiment of the present invention includes a tape supply assembly, a tape pulling assembly, a tape cutting assembly, and a tape suction assembly. The tape supply assembly is used to provide the sealing tape for the sealing paper roll; the tape pulling assembly is arranged between the tape supply assembly and the master roll and is used to pull the tape towards the master roll, and the tape pulling assembly is connected to the adhesive surface of the sealing tape; the cutting end of the tape cutting assembly can extend between the tape pulling assembly and the master roll and is used to cut off the sealing tape; the tape suction assembly is located between the tape cutting assembly and the tape pulling assembly and is used to adsorb the non-adhesive surface of the cut end of the sealing tape. The adsorption end of the tape suction assembly is arranged in a movable structure and can move away from or close to the tape pulling assembly; a sticky surface for pulling the tape is arranged on the tape pulling assembly, and the adhesion between the sticky surface and the sealing tape is less than the adhesion between the sealing tape and the paper material; when the tape suction assembly moves towards the master roll wrapped with paper material, the adhesive surface of the tape between the tape suction assembly and the tape pulling assembly is bonded to the paper material.

[0009] Optionally, the tape supply assembly includes a mounting seat and a buffer member. A moving seat is slidably connected to the mounting seat; the buffer member is arranged between the mounting seat and the moving seat; the tape suction assembly is arranged on the moving seat, and the buffer member is used to absorb the impulse when the tape suction assembly and the tape pulling assembly contact the master roll.

The first fixed seat is arranged on the mounting seat; the sliding rod is slidably connected to the first fixed seat, and one end of the sliding rod is fixedly connected to the moving seat; both ends of the elastic member are respectively connected or abutted to the first fixed seat and the other end of the sliding rod; when the tape suction assembly contacts the master roll, the kinetic energy generated by the master roll on the tape suction assembly is converted into the elastic potential energy of the elastic member through the sliding rod and the moving seat.

[0011] Optionally, the tape suction assembly includes a connecting frame, a telescopic unit, a mounting frame, and an adsorption seat. The connecting frame is arranged on the tape supply assembly; the telescopic unit is arranged on the connecting frame; the mounting frame is arranged at the telescopic end of the telescopic unit; the adsorption seat is arranged on the mounting frame; a suction hole is arranged at the end of the adsorption seat away from the mounting frame, and the suction hole is connected to an external negative pressure device through a pipeline.

[0012] Optionally, the glue pulling assembly includes a driving source, a glue pulling roller, and a first glue pressing wheel. The glue pulling roller is rotatably connected to the paper output end of the mother roll packaging production line; the first glue pressing wheel is rotatably connected to the adsorption end of the glue suction assembly; the driving source is drivingly connected to the glue pulling roller, and the glue sticking surface is formed on the glue pulling roller. When cutting the glue, the first glue pressing wheel is driven by the adsorption assembly to abut against and clamp the adhesive tape with the glue pulling roller, and the driving source drives the glue pulling roller to cooperate with the first glue pressing wheel to pull the adhesive tape in the direction of the mother roll.

[0013] Optionally, the glue pulling roller includes a main shaft and a abutting member. The main shaft is rotatably connected to the paper output end of the mother roll packaging production line; multiple groups of the abutting members are evenly laid on the outer side wall of the main shaft; a gap is provided between the ends of any two adjacent groups of abutting members away from the main shaft, and the ends of multiple groups of the abutting members away from the main shaft form the glue sticking surface.

[0014] Optionally, the abutting member includes a connecting rod and an abutting block. One end of the connecting rod is fixedly connected to the main shaft; the abutting block is arranged in a spherical structure and is fixedly arranged at the end of the connecting rod away from the main shaft.

[0016] Optionally, a non-stick layer is coated on the driving roller. The glue pulling assembly further includes a second glue pressing wheel. The second glue pressing wheel is rotatably connected to the adsorption end of the glue suction assembly. The adsorption assembly can drive the second glue pressing wheel to move towards the driving roller. When the driving roller and the second glue pressing wheel can respectively abut against the glue surface and the non-glue surface of the sealing tape, the driving roller and the second glue pressing wheel clamp the sealing tape.

[0017] One or more of the above technical solutions in the mother roll wrapping and sealing mechanism provided by the embodiments of the present invention have at least one of the following technical effects:

[0018] After the tape is sealed, the adsorption end of the glue suction component moves towards the mother roll. While the tape cutting component cuts the tape, the glue suction component tightly sucks the cut end of the tape. The tape pulling component drives the tape to move a short distance towards the mother roll, and the adsorption end of the glue suction component resets, so that the tape between the adsorption end and the tape pulling component unfolds and the glue surface faces the direction of the mother roll. When the next mother roll wrapped with paper moves close to the tape pulling component and the glue suction component, the outer wall of its paper roll is bonded to the glue surface of the tape. Since the adhesive force of the adhesive surface on the tape pulling component to the tape is less than the adhesive force of the paper material to the tape, when the glue suction component releases the tape, the tape naturally adheres tightly to the paper roll and moves with the paper roll to achieve tape sealing. Compared with the prior art in the tape sealing process after the mother roll is wrapped with paper, due to the special nature of the tape material, the existing automatic feeding equipment cannot effectively clamp and convey the tape, resulting in the obstruction of the automatic tape sealing process and the need for manual tape sealing, and the packaging efficiency of the mother roll cannot be improved. The mother roll paper wrapping and tape sealing mechanism provided by the embodiment of the present invention uses a tape driving roller with appropriate adhesive force and a controllable adsorption component to pull and unfold the tape, effectively realizing automatic tape pasting, overcoming the technical problem that the tape cut direction after cutting cannot be controlled in the traditional paper wrapping device, greatly improving the paper wrapping efficiency, and being beneficial to the development of the enterprise.

[0019] To achieve the above object, a mother roll packaging production line provided by an embodiment of the present invention includes the above-mentioned mother roll paper wrapping and tape sealing mechanism.

[0020] One or more of the above technical solutions in the mother roll packaging production line provided by the embodiment of the present invention have at least one of the following technical effects:

[0021] Since the master roll packaging production line adopts the above-mentioned master roll paper wrapping and sealing mechanism, after the tape is sealed, the adsorption end of the glue suction component moves towards the master roll. While the tape cutting component cuts the tape, the glue suction component sucks and tightens the cut end of the tape. The tape pulling component drives the tape to move a short distance towards the master roll, and the adsorption end of the glue suction component resets, so that the tape between the adsorption end and the tape pulling component unfolds and the glue surface faces the direction of the master roll. When the next master roll wrapped with paper moves close to the tape pulling component and the glue suction component, the outer wall of its paper roll adheres to the glue surface of the tape. Since the adhesive force of the adhesive surface on the tape pulling component to the tape is less than the adhesive force of the paper to the tape, when the glue suction component releases the tape, the tape naturally adheres tightly to the paper roll and moves with the paper roll to achieve sealing. Compared with the prior art in the process of sealing after wrapping the master roll with paper, due to the special nature of the tape material, the existing automated feeding equipment cannot effectively hold and convey the tape, resulting in the obstruction of the automatic sealing process and the need for manual sealing, and the packaging efficiency of the master roll cannot be improved. The master roll paper wrapping and sealing mechanism provided by the embodiment of the present invention uses a tape driving roller with appropriate adhesive force and a controllable adsorption component to pull and unfold the tape, effectively realizing automatic tape sticking, overcoming the technical problem that the tape cut direction after cutting cannot be controlled in the traditional paper wrapping device, greatly improving the paper wrapping efficiency, and being beneficial to the development of enterprises.

[0046] In the embodiments of the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0047] In one embodiment of the present invention, as Figures 1 to 13 shown, a master roll production line is provided, including a transfer device 100 and a paper wrapping device. The paper wrapping device includes a paper material conveying mechanism 200 and a master roll paper wrapping and sealing mechanism 300. The paper material conveying mechanism 200 is used to convey a single sheet of paper for wrapping the master roll to the paper wrapping station of the master roll production line.

[0048] As Figures 1 to 2As shown in the figure, the mother roll wrapping tape sealing mechanism 300 includes a tape supply assembly 310, a tape pulling assembly 320, a tape cutting assembly 330, and a tape suction assembly 340. The tape supply assembly 310 is used to provide the sealing tape for the sealed paper roll. The tape pulling assembly 320 is arranged between the tape supply assembly 310 and the mother roll and is used to pull the tape towards the mother roll. The tape pulling assembly 320 is connected to the adhesive surface of the sealing tape. The cutting end of the tape cutting assembly 330 can extend between the tape pulling assembly 320 and the mother roll and is used to cut off the sealing tape. The tape suction assembly 340 is located between the tape cutting assembly 330 and the tape pulling assembly 320 and is used to adsorb the non-adhesive surface of the cut end of the sealing tape. The adsorption end of the tape suction assembly 340 is arranged in a movable structure and can move away from or close to the tape pulling assembly 320. A glue sticking surface 400 for pulling the tape is arranged on the tape pulling assembly 320, and the adhesion between the glue sticking surface 400 and the sealing tape is less than the adhesion between the sealing tape and the paper material.

[0049] In this embodiment, both the tape supply assembly 310 and the tape pulling assembly 320 are arranged at the paper outlet end of the paper conveying mechanism 200, and both the tape cutting assembly 330 and the tape suction assembly 340 are arranged on the glue material supply assembly.

[0050] Specifically, as Figures 3 to 6 shown in the figure, since the above-mentioned mother roll wrapping tape sealing mechanism 300 is adopted in the mother roll packaging production line, when the tape sealing is completed, the adsorption end of the tape suction assembly 340 moves towards the mother roll. While the tape cutting assembly 330 cuts off the tape, the tape suction assembly 340 sucks and tightens the cut end of the tape. The tape pulling assembly 320 drives the tape to move a short distance towards the mother roll. The adsorption end of the tape suction assembly 340 resets, so that the tape between the adsorption end and the tape pulling assembly 320 unfolds, and the adhesive surface is aligned with the mother roll direction.

[0051] As Figures 7 to 8 shown in the figure, when the next mother roll wrapped with paper material moves close to the tape pulling assembly 320 and the tape suction assembly 340, the outer side wall of its paper roll is bonded to the adhesive surface of the tape. Since the adhesion of the glue sticking surface 400 on the tape pulling assembly 320 to the tape is less than the adhesion of the paper material to the tape, when the tape suction assembly 340 releases the tape, the tape naturally adheres tightly to the paper roll and moves with the paper roll to achieve tape sealing.

[0052] Compared with the prior art in the post-sealing process of wrapping the mother roll with paper, due to the special nature of the tape material, the existing automatic feeding equipment cannot effectively clamp and convey the tape, the automatic tape sealing process is blocked, manual tape sealing is required, and the mother roll packaging efficiency cannot be improved. The mother roll wrapping tape sealing mechanism 300 provided by the embodiment of the present invention uses a tape driving roller with appropriate adhesion and a controllable adsorption assembly to pull and unfold the tape, effectively realizing automatic tape pasting, overcoming the technical problem that the tape cutting direction cannot be controlled in the traditional paper wrapping device, greatly improving the paper wrapping efficiency, and being beneficial to the development of enterprises.

[0053] As Figure 1 、 Figure 2 and Figure 9 shown, further, the tape supply assembly 310 includes a loading roller, a mounting base 311 and a buffer member 312. A moving base 313 is slidably connected to the mounting base 311, and the loading roller is rotatably connected to the moving base 313. In this embodiment, the moving base 313 is slidably adapted to the mounting base 311 through a guide rail pair; the buffer member 312 is disposed between the mounting base 311 and the moving base 313; the glue sucking assembly 340 is disposed on the moving base 313. The buffer member 312 is used to absorb the impulse when the glue sucking assembly 340 and the glue pulling assembly 320 contact the master roll. Using the buffer member 312 to reduce the impact momentum between the glue sucking assembly 340 and the glue pulling assembly 320 and the master roll is beneficial to prevent damage to the master roll, the glue sucking assembly 340 or the glue pulling assembly 320, and improve the structural stability among the tape supply assembly 310, the glue pulling assembly 320 and the glue sucking assembly 340.

[0054] As Figure 9 shown, further, the buffer member 312 includes a first fixed seat 314, a slide rod 315 and an elastic member 316. The first fixed seat 314 is disposed on the mounting base 311; the slide rod 315 is slidably connected to the first fixed seat 314, and one end of the slide rod 315 is fixedly connected to the moving base 313; both ends of the elastic member 316 are respectively connected or abutted to the first fixed seat 314 and the other end of the slide rod 315; when the glue sucking assembly 340 contacts the master roll, the kinetic energy generated by the master roll on the glue sucking assembly 340 is converted into the elastic potential energy of the elastic member 316 through the slide rod 315 and the moving base 313. In this embodiment, the elastic member 316 is a compression spring. The elastic member 316 is sleeved on the slide rod 315. A T-shaped head is provided at the end of the slide rod. The end of the elastic member 316 abuts against the end face of the T-shaped head, and the other end of the elastic member 316 abuts against the moving base 313. When the glue pulling assembly 320 or the glue sucking assembly 340 is subjected to a large impact force, the acting force drives the moving base 313 to move in the direction of the first fixed seat 314 against the elastic force of the elastic member 316. During this process, the kinetic energy generated by the acting force is converted into the elastic potential energy of the elastic member 316, effectively preventing the overall structure from being damaged by excessive impulse. Among them, the structure of the elastic member 316 is flexible. In other embodiments, the elastic member 316 can be a spring sheet or a hydraulic buffer valve.

[0055] As Figure 9As shown in the figure, further, the glue suction assembly 340 includes a connecting frame 341, a telescopic unit 342, a mounting frame 343, and a suction seat 344. The connecting frame 341 is arranged on the tape supply assembly 310; the telescopic unit 342 is arranged on the connecting frame 341; the mounting frame 343 is arranged at the telescopic end of the telescopic unit 342; the suction seat 344 is arranged on the mounting frame 343; a suction hole 345 is arranged at the end of the suction seat 344 away from the mounting frame 343, and the suction hole 345 is connected to an external negative pressure device through a pipeline. In this embodiment, the telescopic unit 342 is a cylinder. The connecting frame 341 is arranged on the mounting seat 311 and extends upward. The telescopic unit 342 is arranged at the end of the connecting frame 341 away from the mounting seat 311. The push rod of the telescopic unit 342 moves in the vertical direction. The number of the suction holes 345 is multiple groups, and the multiple groups of suction holes 345 are distributed at intervals at the end of the suction seat 344. The external negative pressure device is an air compressor. The negative pressure device generates negative pressure in the suction holes 345 so that the suction holes 345 can generate an adsorption force on the non-glue surface of the tape. Using a controllable air suction structure to imitate the action of an operator pinching the tape not only helps with the automation of glue sealing but also can replace manual labor and improve the glue sealing efficiency.

[0056] As Figures 10 to 11 shown in the figure, further, the tape pulling assembly 320 includes a driving source 321, a tape pulling roller 322, and a first glue pressing wheel 323. The tape pulling roller 322 is rotatably connected to the paper material output end of the mother roll packaging production line; the first glue pressing wheel 323 is rotatably connected to the adsorption end of the glue suction assembly 340; the driving source 321 is drivingly connected to the tape pulling roller 322, and the glue sticking surface 400 is formed on the tape pulling roller 322. When cutting the glue, the first glue pressing wheel 323 is driven by the adsorption assembly to abut against and clamp the tape with the tape pulling roller 322, and the driving source 321 drives the tape pulling roller 322 to cooperate with the first glue pressing wheel 323 to pull the tape in the direction of the mother roll.

[0057] In this embodiment, the number of the first glue pressing wheels 323 is two groups. The suction seat 344 includes an extension plate 346 and a suction block 347. The extension plate 346 is arranged at the end of the push rod of the telescopic unit 342, and the extension plate 346 is arranged in the horizontal direction. The suction block 347 is arranged at one end of the extension plate 346, and the suction hole 345 is formed on the suction block 347. The two groups of the first glue pressing wheels 323 are respectively rotatably connected to both ends of the suction block 347. The multiple groups of suction holes 345 form a suction end surface at the end of the suction block 347. The shape of the suction end surface is adapted to and flush with the rolling surface of the first glue pressing wheel 323.

[0058] When it is necessary to drive the tape to move, the first glue pressing wheel 323 cooperates with the tape pulling roller 322 to rotate to drive the tape during the process of pushing the tape. At this time, the negative pressure device stops working; when it is necessary to adsorb the tape after cutting the glue, the negative pressure device sucks the tape tightly through the suction holes 345. The first glue pressing wheel 323 and the suction seat 344 cooperate with each other to realize the pulling and sucking of the tape, with excellent structure and remarkable automatic glue sealing effect.

[0059] like Figure 11 As shown, further, the glue-pulling roller 322 includes a main shaft 324 and abutment 325, the main shaft 324 is rotatably connected to the paper output end of the mother roll packaging production line; multiple groups of abutment 325 are evenly laid on the outer wall of the main shaft 324; a gap is set between the ends of any two adjacent groups of abutment 325 away from the main shaft 324, and the ends of the multiple groups of abutment 325 away from the main shaft 324 form an adhesive surface 400.

[0060] In this embodiment, the main shaft 324 is arranged above the paper outlet of the paper conveying mechanism 200, and the sealing tape and the paper are respectively moved from the upper and lower ends of the main shaft 324 to the paper wrapping station; since the adhesive surface 400 is formed by a plurality of groups of abutment members 325 with spaced ends, when the adhesive surface 400 contacts the adhesive surface of the sealing tape, in fact, the ends of the plurality of groups of abutment members 325 are bonded to the adhesive surface of the sealing tape. Compared with the surface-to-surface bonding between the paper and the adhesive surface of the tape, in this embodiment, the adhesive surface 400 formed by the spaced abutment members 325 is bonded to the adhesive surface of the tape in a point-to-surface bonding manner through a plurality of groups of gaps, and the adhesion force is reduced, thereby allowing the tape to smoothly detach from the adhesive surface 400 to the parent roll of paper, which can not only realize the glue pulling action, but also prevent the tape from staying on the glue pulling roller 322 due to excessive adhesion, thereby realizing automatic glue sealing.

[0061] like Figure 11 As shown, further, the abutment 325 includes a connecting rod and an abutment block, one end of the connecting rod is fixedly connected to the main shaft 324; the abutment block is arranged in a spherical structure and is fixedly arranged at the end of the connecting rod away from the main shaft 324, and the structure of the abutment 325 is flexible, as long as the end of the abutment 325 away from the main shaft 324 can form an abutment surface with a gap similar to a frosted surface or a rolling surface of a car tire.

[0062] like Figure 10As shown in the figure, further, the glue pulling assembly 320 further includes a driving roller 326 and a transmission member 327. The driving roller 326 is rotatably connected to the paper output end of the master roll packaging production line and is spaced on one side of the glue pulling roller 322; one end of the transmission member 327 is drivingly connected to the end of the driving roller 326, and the other end of the transmission member 327 is drivingly connected to the glue pulling roller 322; the driving source 321 is drivingly connected to the driving roller 326. The driving roller 326 and the glue pulling roller 322 rotate synchronously through the transmission member 327, and the rotation directions of the driving roller 326 and the glue pulling roller 322 are the same. Specifically, the driving roller 326 is rotatably connected to the paper output end of the paper conveying mechanism 200 and is located between the glue pulling roller 322 and the tape supply assembly 310. The sealing tape is guided by the driving roller 326 and then adhered to the glue pulling roller 322. The multi-stage transmission is beneficial to preventing the tape from sagging and achieving the tape tensioning effect. In this embodiment, the driving source 321 is a brake motor, and the transmission member 327 is a sprocket chain transmission structure.

[0063] Further, a non-stick layer is coated on the driving roller 326. The glue pulling assembly 320 further includes a second glue pressing wheel 328. The second glue pressing wheel 328 is rotatably connected to the adsorption end of the glue sucking assembly 340. The adsorption assembly can drive the second glue pressing wheel 328 to move towards the driving roller 326. When the driving roller 326 and the second glue pressing wheel 328 can respectively abut against the adhesive surface and the non-adhesive surface of the sealing tape, the driving roller 326 and the second glue pressing wheel 328 clamp the sealing tape. In this embodiment, the second glue pressing wheel 328 is rotatably connected to one end of the extension plate 346 away from the adsorption seat block 347. The non-stick layer is made of nano-ceramic material. The non-stick layer is a structure with mature technology and formation, which will not be elaborated in this embodiment. The adoption of the non-stick layer and the second glue pressing wheel 328 corresponding to the driving roller 326 alone is beneficial to further improving the driving and clamping effects on the tape and improving the stability of tape transportation.

[0064] As Figure 13As shown, further, after the paper material is wound around the outer wall of the mother roll, a capping operation is also required, and the capping on both sides also needs to be tightened with sealing tape. Therefore, in this embodiment, the glue suction assembly 340, the tape supply assembly 310, and the glue cutting assembly 330 are three groups and are evenly distributed in sequence along the width direction of the paper material. The glue suction assembly 340, the glue cutting assembly 330, and the tape supply assembly corresponding to both ends of the paper material are used to cooperate with the glue pulling assembly 320 to perform a glue sealing operation on the paper cover. Among them, since the edge of the traditional paper cover needs to be bent and pressed on the paper tube through a bending structure during installation, there is a possibility that the bent part will return to its original shape. Therefore, in this embodiment, the mother roll paper wrapping and glue sealing mechanism 300 further includes a capping assembly 500. The capping assembly 500 includes a base frame 510, a pushing member 520, and a capping roller 530. The pushing member 520 is a cylinder. The base frame 510 is arranged at the paper outlet end of the paper material conveying mechanism 200. The pushing member 520 is arranged on the base frame 510 and is located above the paper wrapping station. The push rod of the pushing member 520 is aligned with the capping position of the paper material. The capping roller 530 is rotatably connected to the push rod end of the pushing member 520. After the tape adheres to the bent edge of the paper cover, the pushing member 520 pushes the capping roller 530 towards the paper cover, and the capping roller 530 presses the edge of the paper cover tightly on the paper material to improve the paper wrapping effect.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
