Description

Technical Field

[0001] This application relates to the field of laminating machine technology, and more particularly to an automatic cutting laminating machine. Background Technology

[0002] Laminating machines are essential tools in the printing industry, used to apply a translucent film to the surface of materials such as paper, printed materials, or paintings and calligraphy. Through hot pressing or cold lamination processes, laminating machines tightly adhere the translucent film to the material surface, achieving waterproofing, stain resistance, fade prevention, and enhanced durability.

[0003] In order to ensure that the permeable membrane is completely attached to the material surface, the permeable membrane is first attached to the material surface in a manner slightly larger than the material surface size, and then the excess permeable membrane is cut off along the material edge, thereby achieving the purpose of completely attaching the permeable membrane to the material surface.

[0004] In existing technologies, because the laminating machine cannot remove excess permeable membrane, after the material enters the laminating machine to be coated with the permeable membrane, the material needs to be collected and transferred to another trimming device to remove the excess permeable membrane. Since the material needs to be collected and transferred during the removal of excess permeable membrane, this reduces the efficiency of coating the permeable membrane onto the material surface. Furthermore, because the material is thin, it is easily damaged during the collection and transfer process. Utility Model Content

[0005] To address the aforementioned technical problems and achieve at least one advantage of this application, this application provides an automatically cutting laminating machine, wherein the automatically cutting laminating machine comprises:

[0006] The device body includes an mounting body, a pair of pressing rollers, a releasing roller, and a recovery roller. The pair of pressing rollers are rotatably mounted on the mounting body in a relative manner, forming a pressing channel between them. The releasing roller and the recovery roller are both rotatably mounted on the mounting body. The releasing roller has a film roll consisting of a transparent film and a backing paper wound around it. The releasing roller is used to rotate and continuously release the film roll. The pressing channel is used to simultaneously enter the material to be coated and the transparent film separated from the film roll, so that the transparent film separated from the film roll is pressed and adhered to the surface of the material to be coated by the pair of pressing rollers. The recovery roller is used to rewind the backing paper separated from the transparent film in the film roll released from the releasing roller.

The two cutting movement units are respectively used to drive the corresponding cutting element to move horizontally upwards towards the material along a direction perpendicular to the conveying direction of the film-coated material passing through the film pressing channel. The two detection elements are respectively disposed on the two cutting movement units in a manner that allows them to move synchronously with their respective cutting elements, so that when the two detection elements are respectively cut by the corresponding cutting elements... When the edge moving unit is activated, the two detection elements detect in real time the positions of the two sides of the conveying direction of the material covered with the permeable membrane passing through the pressing channel. Then, the two edge moving units move the two edge cutting elements to the two sides of the conveying direction of the material covered with the permeable membrane passing through the pressing channel. The two edge cutting elements are respectively set at the output ends of the two edge adjusting elements. The two edge adjusting elements are used to push the two edge cutting elements to the two sides of the conveying direction of the material covered with the permeable membrane passing through the pressing channel, so that the two edge cutting elements continuously cut off the excess permeable membrane on both sides of the conveying direction of the material covered with the permeable membrane passing through the pressing channel.

The extension direction of the output end of the driving member of each cutting edge moving unit, the extension direction of the corresponding driving member, and the extension direction of the corresponding guide member are all consistent. The moving member of each cutting edge moving unit is threadedly connected to the corresponding driving member and can slide along the extension direction of the corresponding guide member, and is penetrated by the corresponding driving member and the corresponding guide member.

The take-up roller is used to take up the material coated with the translucent film after the excess translucent film has been removed.

[0010] According to one embodiment of this application, the main body of the device further includes a film-bearing roller, which is rotatably disposed on the mounting body and disposed close to one of the pressing rollers. Two cutting edges are disposed on both sides of the material covered with a permeable film that passes through the pressing channel, in a manner that keeps them opposite to the film-bearing roller. Both cutting edges are disposed between the film-bearing roller and one of the pressing rollers.

[0013] According to one embodiment of this application, the pressurizing assembly further includes two pairs of retaining rings, which are respectively disposed on a pair of sliding parts.

[0022] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0023] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] refer to Figures 1 to 5 An automatic cutting laminating machine according to a preferred embodiment of the present application will be described in detail below, wherein the automatic cutting laminating machine includes a device body 10 and at least two cutting edge assemblies 20.

[0026] Specifically, the main body 10 of the device includes a mounting body 11, a pair of pressing rollers 12, a releasing roller 13, and a taking-back roller 14. The pair of pressing rollers 12 are rotatably disposed on the mounting body 11 in a relative manner. A pressing channel 101 is formed between the pair of pressing rollers 12. The releasing roller 13 and the taking-back roller 14 are both rotatably disposed on the mounting body 11. The releasing roller 13 is wound with a coating roll 92 consisting of a transparent film and a backing paper, and the releasing roller 13 is used to rotate and continuously release the coating roll 92. The pressing channel 101 is used to simultaneously enter a material 91 to be coated and the transparent film separated from the coating roll 92, so that the transparent film separated from the coating roll 92 is adhered to the surface of the material 91 to be coated by the clamping of the pair of pressing rollers 12. In other words, as the material 91 to be coated and the permeable film separated from the coating roll 92 continuously and synchronously pass through the pressing channel 101, the material 91 continuously exiting the pressing channel 101 will be coated with the permeable film, thereby achieving the purpose of coating the surface of the material 91 with the permeable film. The recovery roller 14 is used to wind up the backing paper separated from the permeable film in the coating roll 92 released from the unloading roller 13. In other words, after the coating roll 92 is released from the unloading roller 13 and the backing paper constituting the coating roll 92 separates from the permeable film, the backing paper constituting the coating roll 92 will be wound up by the recovery roller 14, and the permeable film constituting the coating roll 92 will be passed into the pressing channel 101 and coated onto the surface of the material 91.

[0027] Both of the aforementioned edge-cutting assemblies 20 include an edge-cutting element 21, an edge-cutting moving unit 22, a detection element 23, and an edge-cutting adjusting element 24. The two edge-cutting elements 21 are respectively disposed on the two edge-cutting moving units 22 via corresponding edge-cutting adjusting elements 24, and the two edge-cutting elements 21 are respectively positioned on opposite sides of the material 91 conveying direction passing through the film-forming channel 101. The two edge-cutting moving units 22 are respectively used to drive the corresponding edge-cutting element 21 to move horizontally upwards towards the material 91 along a direction perpendicular to the conveying direction of the membrane-coated material 91 passing through the film-forming channel 101.

[0028] Two detection elements 23 are respectively disposed on two cutting edge moving units 22 in a manner that allows them to move synchronously with their corresponding cutting edge elements 21. The two detection elements 23 are used to detect in real time the positions of the two sides of the conveying direction of the membrane-coated material 91 passing through the film pressing channel 101 while moving synchronously with the corresponding cutting edge element 21. This allows the two cutting edge moving units 22 to control the movement of the two cutting edge elements 21 to their respective sides in the conveying direction of the membrane-coated material 91 passing through the film pressing channel 101.

[0029] The two cutting edges 21 are respectively disposed at the output ends of the two cutting edge adjusting members 24. The two cutting edge adjusting members 24 are used to push the two cutting edges 21 toward the two sides of the conveying direction of the material 91 covered with the permeable membrane passing through the pressing channel 101, so as to continuously cut off the excess permeable membrane on both sides of the conveying direction of the material 91 covered with the permeable membrane passing through the pressing channel 101 by the two cutting edges 21.

[0030] It is worth mentioning that, after the material 91 covered with the permeable membrane is conveyed out of the pressure channel 101, under the real-time detection of the two detection elements 23, the two cutting elements 21 can move to both sides of the conveying direction of the material 91 covered with the permeable membrane passing through the pressure channel 101 under the drive of the corresponding cutting element moving unit 22. At the same time, the two cutting element adjusting elements 24 can press the two cutting elements 21 against both sides of the conveying direction of the material 91 covered with the permeable membrane passing through the pressure channel 101, and continuously cut off the excess permeable membrane protruding from its sides through the two cutting elements 21. Thus, while the permeable membrane is applied to the surface of the material 91 passing through the pressure channel 101, the excess permeable membrane on the surface of the material 91 conveyed out of the pressure channel 101 is cut off in real time, thereby improving the efficiency of applying the permeable membrane to the surface of the material 91.

[0031] In contrast to the method where the material 91 covered with a permeable membrane, conveyed from the pressing channel 101, is collected and transferred to another device for cutting off excess permeable membrane, the automatic cutting laminating machine of this application can prevent damage to the material 91 and / or the permeable membrane on the surface of the material 91 due to the collection and transfer of the material 91 covered with the permeable membrane, thus ensuring the overall quality of the material 91 covered with the permeable membrane.

[0032] Preferably, both of the pressing rollers 12 are equipped with rubber rollers to prevent the material 91 and / or the permeable film from being damaged as the material 91 to be coated and the permeable film separated from the coating roll 92 continuously and synchronously pass through the pressing channel 101 and are continuously clamped by the pair of pressing rollers 12. Simultaneously, since both of the pressing rollers 12 are equipped with rubber rollers and are elastic, the tightness of the clamping of the material 91 to be coated and the permeable film separated from the coating roll 92 by the pair of pressing rollers 12 can be improved, thereby ensuring that the permeable film is tightly adhered to the surface of the material 91 to be coated.

[0033] It should be noted that at least one of the film pressing rollers 12 is rotatably disposed at both ends of the telescopic cylinder in such a way that it can approach and move away from the other film pressing roller 12, so as to compress the film pressing channel 101 by bringing one of the film pressing rollers 12 close to the other film pressing roller 12, thereby making the material 91 to be coated and the translucent film separated from the coating roll 92 more tightly clamped by the pair of film pressing rollers 12.

[0034] In this embodiment, each of the cutting edge moving units 22 includes a driving member 221, a driving member 222, at least one guide member 223, and a moving member 224. The driving member 221 and the guide member 223 of each cutting edge moving unit 22 are mounted on the mounting body 11. The driving member 222 of each cutting edge moving unit 22 is disposed at the output end of the corresponding driving member 221 in a manner that allows it to be driven by the corresponding driving member 221. The extending direction of the driving member 222 of each cutting edge moving unit 22 is perpendicular to the conveying direction of the membrane-coated material 91 conveyed from the film pressing channel 101. The extending directions of the output end of the driving member 221, the corresponding driving member 222, and the corresponding guide member 223 of each cutting edge moving unit 22 are all consistent. The movable element 224 of each of the cutting edge moving units 22 is threaded through the corresponding driving element 222 and the corresponding guide element 223 in a manner that maintains a threaded connection to the corresponding driving element 222 and is slidable along the extension direction of the corresponding guide element 223. The detection element 23 and the corresponding cutting edge adjusting element 24 of each cutting edge assembly 20 are mounted on the movable element 224 of the corresponding cutting edge moving unit 22.

[0035] As an example, when the driving member 221 of each of the cutting edge moving units 22 drives the corresponding driving member 222, since the moving member 224 of each of the cutting edge moving units 22 is threadedly connected to the corresponding driving member 222 in such a way that it is penetrated by the corresponding driving member 222 and the corresponding guide member 223, the moving member 224 of each of the cutting edge moving units 22 cannot follow the rotation of the corresponding driving member 222. As a result, the moving member 224 of each of the cutting edge moving units 22 slides along the extension direction of the corresponding moving member 224, so that the corresponding detection member 23, the corresponding cutting edge adjusting member 24 and the corresponding cutting member 21 move as a whole along the conveying direction perpendicular to the conveying direction of the material 91 covered with the permeable membrane conveyed from the pressure film channel 101.

[0036] In each of the cutting edge moving units 22, the driving component 221 is implemented to include a drive motor. The driving component 222 of each of the cutting edge moving units 22 is implemented to include a lead screw.

[0037] In another modified embodiment, each of the cutting edge moving units 22 includes a telescopic cylinder in real time, and the telescopic direction of each cutting edge moving unit 22 is perpendicular to the conveying direction of the membrane-coated material 91 conveyed from the film pressing channel 101. The detection element 23 and the corresponding cutting edge adjusting element 24 of each cutting edge assembly 20 are disposed at the output end of the corresponding cutting edge moving unit 22, so that when the output end of each cutting edge moving unit 22 is telescopic, the corresponding detection element 23, the corresponding cutting edge adjusting element 24 and the corresponding cutting element 21 are moved as a whole along the conveying direction perpendicular to the conveying direction of the membrane-coated material 91 conveyed from the film pressing channel 101.

[0038] To enable those skilled in the art to understand this application, in at least one embodiment of this application, the example is provided by assuming that each of the cutting edge moving units 22 includes the driving member 221, the driving member 222, at least one of the guide members 223 and the moving member 224.

[0039] In this embodiment, each of the detection elements 23 is implemented to include a laser sensor.

[0040] As an example, during the process of each of the moving members 224 driving the corresponding detection member 23, the corresponding edge adjustment member 24, and the corresponding edge member 21 to move along the conveying direction perpendicular to the conveying direction of the material 91 covered with the permeable membrane from the pressing channel 101, each detection member 23 will monitor the positions of both sides of the material 91 covered with the permeable membrane passing through the pressing channel 101 in real time. After each detection member 23 detects the two sides of the material 91 covered with the permeable membrane, it will again control each driving member 221 to drive the corresponding driving member 222. Under the drive of the moving member 224 of each edge moving unit 22, the corresponding edge member 21 will be directed toward the two sides of the material 91 covered with the permeable membrane. The two edge adjustment members 24 will push the two edge members 21 toward the two sides of the conveying direction of the material 91 covered with the permeable membrane passing through the pressing channel 101 and cut off the excess permeable membrane.

[0041] Preferably, both of the edge adjusting members 24 include telescopic cylinders. Both edge cutting members 21 include blades, and are detachably mounted to the output ends of the corresponding edge adjusting members 24 by screws. The telescopic direction of the output ends of the two edge adjusting members 24 is such that the corresponding edge cutting member 21 can be pushed towards both sides of the conveying direction of the membrane-coated material 91 passing through the pressure film channel 101.

[0042] It is understood that when at least one of the cutting edge members 21 needs to be replaced due to wear, the worn cutting edge member 21 is removed and replaced by unscrewing the corresponding screw.

[0043] Specifically, the main body 10 of the device further includes an unwinding roller 15 and a take-up roller 16. Both the unwinding roller 15 and the take-up roller 16 are rotatably mounted on the mounting body 11. The unwinding roller 15 winds the material 91 to be coated, continuously releasing the material 91 through rotation. The take-up roller 16 is used to reel in the coated material 91 after excess film has been removed, facilitating transport and transfer.

[0044] Compared to manually feeding the material 91 to be coated into the film-pressing channel 101, the continuous feeding of the material 91 to be coated from the unwinding roller 15 into the film-pressing channel 101 reduces the probability of relative displacement between the material 91 to be coated entering the film-pressing channel 101 and the permeable film entering the film-pressing channel 101, thereby improving the stability of the material 91 to be coated when it enters the film-pressing channel 101 and is coated with the permeable film.

[0045] Preferably, the take-up roller 16 is located on the conveying path of the material 91 covered with permeable film, which is conveyed out from the film pressing channel 101 and has had excess permeable film removed, so that the take-up roller 16 can take up the material 91 covered with permeable film after the excess permeable film has been removed.

[0046] In this embodiment, one end of the pressing roller 12, the take-up roller 14, the unwind roller 15 and the take-up roller 16 are respectively connected to the output end of the drive motor, so that the pressing roller 12, the take-up roller 14, the unwind roller 15 and the take-up roller 16 are driven by the corresponding drive motors.

[0047] Preferably, the main body 10 of the device further includes a film-bearing roller 17. The film-bearing roller 17 is rotatably disposed on the mounting body 11, and the film-bearing roller 17 is disposed close to one of the pressing rollers 12. The two cutting edges 21 are respectively disposed on both sides of the material 91 covered with a permeable film passing through the pressing channel 101, in a manner that maintains opposition to the film-bearing roller 17. Both cutting edges 21 are disposed between the film-bearing roller 17 and one of the pressing rollers 12.

[0048] It should be noted that when the two cutting edges 21 are moved to the sides of the conveying direction of the material 91 covered with permeable film passing through the film pressing channel 101 by the cutting edge adjusting member 24, the two ends of the material 91 covered with permeable film passing through the film pressing channel 101 are supported by the film receiving roller 17 and one of the film pressing rollers 12, respectively. This makes the material 91 covered with permeable film passing through the film pressing channel 101 more stable and makes it easier to keep the material 91 covered with permeable film passing through the film pressing channel 101 taut. This makes it easier to remove excess permeable film from the material 91 covered with permeable film passing through the film pressing channel 101 by the two cutting edges 21.

[0049] Preferably, the main body 10 of the device further includes a material support member 18. The material support member 18 is fixed to the mounting body 11. The material support member 18 is located between the unwinding roller 15 and the pressing roller 12. The material support member 18 is used to support the material 91 to be coated released from the unwinding roller 15, so that the material 91 to be coated is in a flat state before entering the pressing channel 101, thereby preventing the material 91 to be coated from being damaged by wrinkles when entering the pressing channel 101.

[0050] In this embodiment, the automatically cutting laminating machine further includes a pressure assembly 30. The pressure assembly 30 includes a pair of sliding mounting members 31 and a pressure roller 32. The pair of sliding mounting members 31 are mounted to the mounting body 11 in a relatively opposing manner, and are positioned above the film-feeding roller 13 in the direction of gravity. Each pair of sliding mounting members 31 has a sliding channel 3101 formed along directions that allow them to approach and move away from the film-feeding roller 13. That is, the bottoms of the two sliding channels 3101 in the direction of gravity are close to the film-feeding roller 13. The pressure roller 32 includes a film-pressing portion 321 and a pair of rotating portions 322. The pair of rotating portions 322 are positioned at both ends of the film-pressing portion 321 in the axial direction of the film-pressing portion 321 in a manner that maintains coaxiality with the film-pressing portion 321. The pair of sliding portions 322 of the pressure roller 32 are rotatably held inserted into the sliding channels 3101 of the pair of sliding mounts 31 in such a way that they can slide along the corresponding sliding channels 3101, and the film pressing portion 321 of the pressure roller 32 is held in contact with the film roll 92 wound by the film unloading roller 13.

[0051] It is understood that as the film-releasing roller 13 continuously rotates to release the film roll 92, and the radius of the film roll 92 wound by the pressure roller 12 gradually decreases, under the action of gravity, a pair of sliding portions 322 of the pressure roller 32 will slide down in the corresponding sliding channels 3101, so that the pressure portion 321 of the pressure roller 32 will always remain pressed against the film roll 92 wound by the film-releasing roller 13 under the action of gravity.

[0052] It should be noted that, due to the tension of the coating roll 92 itself, when the unwinding roller 13 continuously rotates to unwind the coating roll 92, the coating roll 92 wound on the unwinding roller 13 will wobble, which will affect the stability of the unwinding roller 13 as it continuously rotates to unwind the coating roll 92. However, because the pressing part 321 of the pressure roller 32 is always kept pressed against the coating roll 92 wound on the unwinding roller 13 under the action of gravity, the unwinding roller 13 remains stable as it continuously rotates to unwind the coating roll 92.

[0053] Preferably, the radial dimension of the pair of sliding portions 322 is smaller than the radial dimension of the pressing portion 321. The pressurizing assembly 30 also includes a pair of bearing members 33. The pair of bearing members 33 are respectively held in the pair of sliding channels 3101 in a manner that allows them to slide along the pair of sliding channels 3101 respectively. The pair of bearing members 33 are rotatably sleeved on the pair of sliding portions 322 of the pressure roller 32 respectively.

[0054] In this embodiment, both of the bearing components 33 are implemented to include bearings.

[0055] Understandably, during the continuous rotation of the film-releasing roller 13 to release the coated roll 92, the film-pressing portion 321 of the pressure roller 32 remains pressed against the coated roll 92, thereby driving a pair of sliding portions 322 to rotate within a pair of sliding channels 3101. Simultaneously, since a pair of bearing members 33 are rotatably mounted on the pair of sliding portions 322, they are lifted to prevent jamming when the pair of sliding portions 322 rotate within the pair of sliding channels 3101, thereby improving the overall smoothness of rotation of the pressure roller 32 and preventing jamming during rotation of the pressure roller 32 from hindering the continuous rotation of the film-releasing roller 13 to release the coated roll 92.

[0056] Preferably, the pressurizing assembly 30 further includes two pairs of retaining rings 34. The two pairs of retaining rings 34 are respectively disposed on a pair of sliding portions 322. Each pair of retaining rings 34 is located on opposite sides of the corresponding bearing member 33 along its axial direction, one closer to and one further away from the pressing portion 321. The radial dimension of each pair of retaining rings 34 is larger than the radial dimension of the corresponding bearing member 33.

[0057] The two pairs of retaining rings 34 prevent the pressure roller 32 and the pair of bearing members 33 from moving axially as a whole, thereby preventing the pair of sliding parts 322 of the pressure roller 32 from driving the pair of bearing members 33 to fall out of the corresponding sliding channel 3101.

[0058] Specifically, the pressing part 321 has several grooves on its circumferential side along the axial direction to increase the friction between the pressing part 321 and the coating roll 92 wound on the unwinding roller 13, so that the pressing part 321 is driven to rotate by the coating roll 92 in a timely manner, reducing the probability of relative displacement between the pressing part 321 and the coating roll 92, and thus reducing the probability of the pressing part 321 scratching the film in the coating roll 92.

[0059] Preferably, the film-releasing roller 13 includes a winding shaft 131 and a fixed shaft 132. The winding shaft 131 is rotatably mounted on the fixed shaft 132 via bearings. The winding shaft 131 is wound with the film-coating roll 92 consisting of a transparent film and a backing paper, so that the film-coating roll 92 is continuously released by the rotation of the winding shaft 131 of the film-releasing roller 13. The mounting body 11 has a pair of insertion slots 1101. The pair of insertion slots 1101 are respectively used to receive the two ends of the fixed shaft 132. The automatically cutting laminating machine also includes a pair of fixing components 40. The pair of fixing components 40 are movably disposed between the two ends of the fixed shaft 132 and the mounting body 11 so as to press and fix the two ends of the fixed shaft 132 into the pair of insertion slots 1101 respectively.

[0060] Specifically, each pair of fixing components 40 includes a pressure shaft body 41 and a fixing unit 42. The pair of pressure shaft bodies 41 are respectively held against the two ends of the fixing shaft 132 in a manner opposite to the opening direction of the pair of insertion slots 1101. One end of each pair of pressure shaft bodies 41 is rotatably connected to the mounting body 11. A snap-fit ​​slot 4101 is formed at the other end of each pair of pressure shaft bodies 41, away from the connection to the mounting body 11. Each pair of fixing units 42 includes a rotating member 421 and a fixing member 422. The pair of rotating members 421 are rotatably connected to the mounting body 11 in a manner that allows them to rotatably and partially snap into the corresponding snap-fit ​​slots 4101. The pair of fixing members 422 are threadedly connected to the corresponding rotating members 421 in a manner that allows them to move along the extension direction of the corresponding rotating member 421 and respectively press the pair of pressure shaft bodies 41 against the two ends of the fixing shaft 132.

[0061] It is understood that after the pair of pressure shaft bodies 41 rotate at the mounting body 11 and press against the two ends of the corresponding fixed shaft 132, the pair of rotating members 421 will rotate at the mounting body 11 and partially engage with the corresponding engaging groove 4101. During the process of the pair of fixing members 422 moving along the rotating member 421 and pressing against the corresponding pressure shaft body 41 while maintaining a threaded connection to the rotating member 421, the pair of fixing members 422 will press the pair of pressure shaft bodies 41 against the two ends of the fixed shaft 132, thereby pressing and fixing the two ends of the fixed shaft 132 into the pair of engaging grooves 1101 to prevent the two ends of the fixed shaft 132 from detaching from the engaging grooves 1101.

[0062] It should be noted that, since the winding shaft 131 is rotatably sleeved on the fixed shaft 132 via bearings, when both ends of the fixed shaft 132 are respectively pressed and fixed by a pair of pressure shaft bodies 41, the winding shaft 131 of the film-releasing roller 13 can rotate relative to the fixed shaft 132 and continuously release the film-coated roll 92. Specifically, since both ends of the fixed shaft 132 are respectively pressed and fixed by a pair of pressure shaft bodies 41, the winding shaft 131 is more stable during rotation, allowing it to stably release the film-coated roll 92 without skewing.

[0063] Furthermore, the pair of fixing members 422 move along the rotating member 421 and away from the corresponding pressure shaft body 41 while maintaining a threaded connection to the rotating member 421. After the pair of rotating members 421 rotate and move away from the corresponding pressure shaft body 41 while connected to the mounting body 11, the pair of pressure shaft bodies 41 can rotate and move away from the two ends of the corresponding fixing shaft 132 while connected to the mounting body 11. This allows the entire film-releasing roller 13 that has released the film roll 92 to be removed so that a new film-releasing roller 13 with the film roll 92 wound on it can be replaced.

[0064] Preferably, each of the pair of fixing components 40 further includes a spacer 43. The pair of spacers 43 are respectively disposed between the two ends of the pair of pressure shaft bodies 41 and the fixing shaft 132.

[0065] As an example, the separator 43 is made of cardboard.

[0066] It should be noted that, since both the pressure shaft body 41 and the fixed shaft 132 are made of metal, in order to prevent the two ends of the pressure shaft body 41 from being unable to hold and fix the two ends of the fixed shaft 132 due to excessive smoothness at the contact points between the two ends of the pressure shaft body 41 and the fixed shaft 132, the provision of a pair of isolation members 43 can enhance the friction at the contact points between the two ends of the pressure shaft body 41 and the fixed shaft 132, so that the two ends of the fixed shaft 132 are more stably held and fixed by the pair of pressure shaft bodies 41.

[0067] Specifically, each of the pair of sliding mounting members 31 is further provided with a temporary space 3102. The pair of temporary spaces 3102 are respectively adapted to the pair of bearing members 33. The pair of temporary spaces 3102 are respectively connected to the top of the pair of sliding channels 3101 in the direction of gravity via a connecting channel. The height of the connecting channel in the direction of gravity near the corresponding sliding channel 3101 is not lower than the height of the connecting channel near the corresponding temporary space 3102.

[0068] As an example, the pressure roller 32, the pair of bearing members 33, and the two pairs of retaining rings 34 are raised as a whole along the extending direction of the sliding channel 3101. After the pair of bearing members 33 pass through the corresponding sliding channel 3101 and the corresponding connecting channel in sequence and are placed into the corresponding temporary space 3102, the pressure roller 32, the pair of bearing members 33, and the two pairs of retaining rings 34 are kept away from the film-releasing roller 13. This makes it easier to remove the film-releasing roller 13 after releasing the film roll 92, and thus facilitate the replacement of a new film-releasing roller 13 with the film roll 92 wound on it.

[0069] Specifically, since the gravity direction height of the pair of connecting channels near the corresponding sliding channel 3101 is not lower than the gravity direction height near the corresponding temporary space 3102, when the pair of bearing members 33 respectively enter the corresponding connecting channels, it prevents the pair of bearing members 33 from sliding back to the corresponding sliding channel 3101 under the action of gravity, so as to prevent damage when the worker takes out the film-releasing roller 13 as a whole after releasing the film roll 92.

[0070] Preferably, the automatically cut laminating machine further includes a plurality of guide rollers 50. The plurality of guide rollers 50 are rotatably disposed on the mounting body 11. At least one of the guide rollers 50 is disposed between the unwinding roller 15 and the material carrier 18, so as to guide the material 91 to be laminated, released from the unwinding roller 15, to the surface of the material carrier 18 via the guide roller 50 located between the unwinding roller 15 and the material carrier 18. At least one of the guide rollers 50 is disposed between the film-bearing roller 17 and the take-up roller 16, so as to guide the material 91, after excess film has been removed by the film-bearing roller 17 and laminated, to the take-up roller 16 for winding via the guide roller 50 located between the film-bearing roller 17 and the take-up roller 16.

[0071] It is understood that the axial directions of the pair of pressing rollers 12, the unloading rollers 13, the take-up rollers 14, the unwinding rollers 15, the take-up rollers 16, the receiving rollers 17, the pressure rollers 32, and the plurality of guide rollers 50 are kept parallel.

The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
