Description

Technical Field

[0001] The present invention relates to the technical field of film laminating and cutting, and specifically to a film laminating and cutting machine for plates. Background Art

[0002] In the processing of wooden plates, it is generally necessary to sand the plates to make them smoother, flatter, and have a uniform thickness. After the finished product is processed, a laminating machine is generally required to wrap a protective film on the surface of the plates for packaging to avoid frictional wear on the surface of the plates during transportation. Therefore, corresponding laminating machines have been developed to achieve automatic film lamination.

[0003] For example, CN217456492U discloses a plate laminating machine. It conveys the plates through a conveyor belt, and the positioning blocks on the positioning belt are used to hold the front end of the plates, so as to ensure that the gaps between each plate are the same; the protective film is attached between adjacent plates through the cooperation of a heating roller and a pressure lower roller; the punching head moves downward through a punching cylinder and punches the protective film between adjacent plates.

[0004] However, there are the following defects:

[0005] 1. The gap between each plate is only limited on the conveyor belt, and the plates coming out of the conveyor belt still need to be conveyed through an upper conveying roller, a lower conveying roller, a heating roller, a pressure lower roller, and a conduction roller group in sequence, and then to the film laminating and cutting mechanism. However, the upper conveying roller, the lower conveying roller, the heating roller, the pressure lower roller, and the conduction roller group are respectively driven by different driving devices, so it is difficult to ensure that their running speeds are consistent. When each plate is conveyed to the position of the film laminating and cutting mechanism, it is difficult to ensure that the gaps between them are the same.

[0006] 2. When the upper conveying roller, the lower conveying roller, the heating roller, the pressure lower roller, and the conduction roller group convey the plates, different frictions will be generated on each plate. Especially when conveying large-sized plates or when the plates are conveyed over a long distance, the distance between adjacent plates at the position of the film laminating and cutting mechanism will be larger or smaller, resulting in the punching head being unable to accurately punch the protective film between adjacent plates and easily hurting the plates.

[0007] 3. When the punching head moves downward, it will generate a downward force on the protective film, and this downward force will be converted into a pulling force acting on the adjacent plates, causing the adjacent plates to move towards each other, resulting in collisions between adjacent plates or collisions between the plates and the punching head, damaging the plates or the punching head.

[0008] 4. It is impossible to minimize the distance between adjacent plates, that is, the distance reserved between adjacent plates is relatively large, and more protective film is required to achieve the wrapping and protection of the plates, resulting in waste.

[0009] Therefore, it is necessary to further improve. Summary of the Invention

[0051] 4. The cutting and laminating machine cuts the film for the front and rear adjacent plates in a sliding manner, without generating a downward pulling force on the adjacent plates, thereby avoiding problems such as the adjacent plates moving towards each other's positions during film cutting, resulting in collision between adjacent plates or collision between the plates and the cutting and laminating machine, and further ensuring the unity of the gaps between adjacent plates.

[0125] A supporting plate 75, a film cutting and laminating conveyor belt tensioning roller group 76, and a film cutting and laminating conveyor belt pressing roller 77 are also arranged on the film cutting and laminating frame 47.

[0126] The pallet 75 is located below the film cutting device H, and its front and rear ends are flush with the film cutting and laminating conveyor belts 44 on the film cutting and laminating feeding rack 40 and the film cutting and laminating discharging rack 41 respectively, enabling the pallet 75 to support the board so that the board can smoothly enter the pallet 75 from the film cutting and laminating feeding rack 40 and enter the film cutting and laminating discharging rack 41 from the pallet 75.

[0127] The pallet 75 is provided with an avoidance groove 78 corresponding to the film cutting knife. When the film cutting knife works, it slides into the avoidance groove 78 from one side and cuts the protective film 51.

[0128] The film cutting and laminating conveyor belt tensioning roller group 76 is rotatably arranged on the film cutting and laminating machine frame 47 in an adjustable manner to realize the adjustment of the tension of the film cutting and laminating conveyor belt 44.

[0129] The film cutting and laminating conveyor belt 44 is wound around the driving end roller 42, the film cutting and laminating conveyor belt tensioning roller group 76, and the driven end roller 43.

[0130] The film cutting and laminating conveyor belt pressing roller 77 is located below the pallet 75 and presses down on the film cutting and laminating conveyor belt 44, and is rotatably arranged on the film cutting and laminating machine frame 47; the film cutting and laminating machine frame 47 is also provided with an encoder 79 corresponding to the rotation of the film cutting and laminating conveyor belt pressing roller 77.

[0133] As Figures 18 - 21 shown, the jacking and conveying process of this embodiment is as follows:

[0134] First, the first board is placed on the feeding conveyor device A manually or by other mechanical devices, and then the feeding conveyor belt group E conveys the first board;

[0135] Second, the first board is positioned on the conveying positioning plate 80. After the lifting photoelectric sensor senses that the first board is conveyed in place, the lifting photoelectric sensor sends a signal to the longitudinal driver 5, and the longitudinal driver 5 drives the lifting frame 6 to rise, so that the first board is lifted and separated from the feeding conveyor belt group E;

[0136] III. After the first sheet leaves the feeding conveyor belt group E, the transverse sliding seat 2 slides towards the direction of the cutting and laminating conveying device B driven by the transverse driver 3, so that the first sheet is conveyed above the cutting and laminating feeding rack 40. At the same time, the second sheet is conveyed onto the feeding conveyor device A manually or by other mechanical devices, and then the feeding conveyor belt group E conveys the second sheet;

[0137] IV. After the descending photoelectric sensor senses that the first sheet is conveyed in place, the descending photoelectric sensor sends a signal to the longitudinal driver 5, and the longitudinal driver 5 drives the lifting frame 6 to descend, so that the first sheet is placed on the cutting and laminating conveyor belt 44 of the cutting and laminating feeding rack 40;

[0138] V. The cutting and laminating conveyor belt 44 starts to work driven by the cutting and laminating conveyor 39 and conveys the first sheet towards the direction of the cutting and laminating machine D. At the same time, the transverse sliding seat 2 slides towards the direction of the feeding conveyor device A driven by the transverse driver 3, so that the lifting frame 6 is reset and is again located below the feeding conveyor belt group E, and continues to perform the lifting operation on the second sheet positioned on the conveying and positioning plate 80;

[0139] VI. When the first sheet is conveyed to the cutting and laminating machine D, the upper pressing film roller 58 of the feeding end pressing film roller group 49 slides towards the direction of the lower driving roller 59 driven by the screw elevator 61, and presses the protective film 51 on the first sheet. Subsequently, the cutting and laminating conveyor 39 stops working, and the cutting and laminating conveyor belt 44 of the cutting and laminating feeding rack 40 is emptied and waits for the second sheet; ( Figure 18 as shown)

[0140] VII. Repeat steps II to V, and convey the second sheet, so that the distance between the front end face of the second sheet and the rear end face of the first sheet is unified and minimized;

[0141] VIII. When the distance between the first and second sheets is below the film cutting device H, the film cutting knife is inclined driven by the film cutting knife floating cylinder 73. At the same time, the synchronous belt 71 starts to work driven by the film cutting knife driving motor 66 and drives the film cutting knife sliding seat 72 to slide, so that the film cutting knife enters the distance between the first and second sheets from one side and exits from the other side of the distance between the first and second sheets, so as to cut off the protective film 51;

[0142] IX. After the protective film 51 is cut off, the film cutting knife is leveled driven by the film cutting knife floating cylinder 73. At the same time, the synchronous belt 71 starts to work driven by the film cutting knife driving motor 66 and drives the film cutting knife sliding seat 72 to perform a reset sliding and wait for the next work; Subsequently, the cutting and laminating conveyor belt 44 starts to work driven by the cutting and laminating conveyor 39, and continues to convey the first and second sheets after laminating;

[0143] 10. The upper film pressing roller 58 of the film pressing roller set 50 at the discharge end slides downward in the direction of the lower driving roller 59 under the drive of the screw lift 61, and presses the protective film 51 on the first and second laminated plates again to ensure that the protective film 51 can be attached to the first and second laminated plates;

[0144] 11. The first and second laminated plates after film lamination are conveyed to the film cutting and discharging rack 41 through the film cutting and conveying belt 44 and are discharged.

[0145] Among them, the conveying direction of the plate is as shown by the X arrow in Figure 3 . The moving direction of the lifting and conveying device C is as shown by the Y arrow in Figure 3 . The moving direction of the protective film 51 is as shown by the Z arrow in Figure 3 and Figure 4 .

[0146] In this embodiment, the lifting and conveying device C uses a series of actions such as lifting, sliding, and descending to convey the plates, so that the distance between adjacent plates conveyed from the feeding conveying device A to the film cutting and conveying device B can be unified and minimized. Moreover, since the entire film cutting and conveying device B is driven by a single power source, and the entire film cutting and conveying device B also adopts the method of stopping the front plate at the designated position of the film cutting machine D and waiting for the rear plate to be conveyed in place by the lifting and conveying device C before continuing to convey the plates, it can be ensured that the distance between adjacent plates conveyed through the film cutting and conveying device B will not change when entering the film cutting machine D, and it can be ensured that the distance between adjacent plates is within 5 mm, so that the film cutting machine D can laminate the plates with less protective film 51 and can accurately cut the protective film 51 of adjacent plates.

[0147] The above is the preferred solution of the present invention, which shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
