As shown in fig. 4, the paper film laminating apparatus 100 further includes a base 90, the base 90 is used for supporting the first conveying mechanism 20, the second conveying mechanism 30, and the like, and the first conveying mechanism 20 and the second conveying mechanism 30 are sequentially and alternately disposed on the base 90 along the conveying direction of the film 102.
With continued reference to fig. 4, the film feeding mechanism 10 is suspended from the base 90. The film feeding mechanism 10 may be supported on the base 90, or may be supported on another member having a supporting function. In one embodiment, the film feeding mechanism 10 is located above the base 90 in a direction perpendicular to the base 90, so that when the film feeding mechanism 10 releases the film 102, the film 102 naturally vertically descends onto the first conveying member 22, and power is saved. In other embodiments, the position where the film feeding mechanism 10 is disposed is not limited to the above, for example, the film feeding mechanism 10 may be disposed horizontally with the first conveying member 22 or below the first conveying member 22 relatively.
In one embodiment, the film feeding mechanism 10 includes a film feeding roller 11 and a film feeding motor (not shown), and the film feeding roller 11 is wound with a film 102 to form a roll of the film 102. The film feeding motor is connected with the film feeding roller 11 and drives the film feeding roller 11 to rotate, so that the film placing or film conveying 102 action is realized. Of course, the type of the film feeding mechanism 10 is not limited to the above-described structure, and other structures having a function of feeding the film 102 may be adopted.
In one embodiment, referring to fig. 4, the paper film laminating product further comprises a slitting mechanism 80, the slitting mechanism 80 being disposed adjacent to the second conveyor 32 for cutting the film 102 on the second conveyor 32. When the paper film laminated product formed by laminating the film 102 and the paper board 101 is conveyed to the slitting mechanism 80 by the second conveying member 32, the slitting mechanism 80 slits the film 102, and the slit paper film laminated product is conveyed to a storage station or a storage basket.
Referring to fig. 4, the slitting mechanism 80 is disposed on the base 90, and the first conveying mechanism 20, the second conveying mechanism 30 and the slitting mechanism 80 are sequentially disposed on the base 90 at intervals along the length direction of the first conveying member 22, so that the mechanisms are arranged along the processing procedure, the layout is compact, the space is saved, and the mechanisms are connected to each other for processing, which is beneficial to improving the processing efficiency.
In one embodiment, as shown in fig. 4, the slitting mechanism 80 comprises a slitting blade 81 and a fifth driving member 83 (not shown), and the fifth driving member 83 is connected to the slitting blade 81 for driving the slitting blade 81 to move and slit the film 102. Since the second conveying member 32 is continuously operated while the film 102 is extended, so that the excessive film 102 exists between the two adjacent paper-film-covered products, the cutting knife 81 needs to perform two cutting operations to cut the films 102 at both ends of each paper sheet 101 having been paper-film-covered.
Further, referring to fig. 4, the slitting mechanism 80 further includes a rocker 82, one end of the rocker 82 is connected to a fifth driving member 83, the other end of the rocker 82 is connected to the slitting knife 81, and the fifth driving member 83 drives the rocker 82 to control the slitting knife 81 to move up and down for slitting.

It should be noted that the first conveying member 22 and the second conveying member 32 are disposed at an interval, and the distance between the two members is the extended gap 35, but of course, an opening or a gap for the film 102 to pass through and to sink in an extended manner may be specially formed between the two members and on the base 90.
In one embodiment, referring to fig. 4 to 6, the first conveying mechanism 20 further includes a first suction device (not shown), the first conveying device 22 is provided with a first suction hole 23, and the first suction device sucks the film 102 onto the surface of the first conveying device 22 through the first suction hole 23, so as to suck the film 102 and convey the film 102. Of course, in other embodiments, the manner in which the first conveyance member 22 sucks the film 102 is not limited to the above, and for example, a plurality of suction pads or the like may be provided on the first conveyance member 22.
In one embodiment, the first suction device is a suction pump, and suction by the suction pump generates a suction air flow at the first suction holes 23, so as to suck the film 102 on the first conveying member 22. In other embodiments, other suction devices may be used for the first conveying member 22.
As shown in fig. 4 and 6, the second conveying mechanism 30 further includes a second adsorbing member (not shown), the second conveying member 32 is provided with a second adsorbing hole 33, and the second adsorbing member adsorbs the combined paper sheet 101 and film 102 to the surface of the second conveying member 32 through the second adsorbing hole 33 for conveying. Of course, in other embodiments, the manner in which the second conveying member 32 sucks the film 102 is not limited to the above, and for example, a plurality of suction cups or the like may be provided on the second conveying member 32.
Suppose the first transfer member 22 is running at a speed V 1 ，T 1 The length of time the film 102 is conveyed by the first conveying member 22, the length L of the film 102 conveyed by the first conveying member 22 1 Is L 1 =V 1 *T 1 The second conveying member 32 is operated at a speed V 2 ，T 2 The length L of the film 102 conveyed by the second conveying member 32 for the length of time the film 102 is conveyed by the second conveying member 32 2 Is L 2 =V 2 *T 2 The lengthened length of the middle part of the film 102 is S, then S = V 1 *T 1 －V 2 *T 2 . As can be seen from the formula, the film 102 lengthening length S is related to the speed difference and time between the first conveying member 22 and the second conveying member 32. Therefore, the speed difference V between the first conveying member 22 and the second conveying member 32 in the unit time can be controlled in the embodiment 1 －V 2 To precisely control the extension S, it is also possible to fix the speed difference between the first conveying member 22 and the second conveying member 32, by controlling the time difference T 1 －T 2 So as to precisely control the lengthening length S of the film 102 and realize the infinite lengthening of the film 102.
It is to be noted that the speed V of the second transfer member 32 2 Which may be equal to zero, when the second conveyor 32 stops running and the first conveyor 22 continues to run, it may also be considered that there is a speed difference between the first conveyor 22 and the second conveyor 32, which may also achieve an extended accumulation of film 102.
In one embodiment, the first transfer mechanism 20 and the second transfer mechanism 30 are both belt transfer mechanisms, and thus the first conveyor 22 is a first belt, the second conveyor 32 is a second belt, and the relationship between angular velocity and rotational speed is: v 1 ω = 2n (where n represents a rotation speed of the conveyor belt and ω represents an angular velocity), it is known that the conveyor belt rotates by θ = ω t (where θ represents the rotation angle and t represents time) per unit time, so that the length L = (θ/360) 2 pi r = (ω t/360) 2 pi r = (2 pi nt/360) 2 pi r = which is taken away per unit timePi 2nrt/90, where pi is a fixed value as the radius r of the transfer axis, and the length L of the film 102 transferred is the same as the length of the belt traveled per unit time, assuming that the first belt is rotating at n 1 The second conveyor belt has a rotational speed n 2 The middle of the membrane 102 is lengthened by a length S = L in the same operation time period t 1 -L 2 =π2n 1 rt/90-π2n 2 rt/90=π2(n 1 -n 2 ) rt/90, from the equation, the speed difference n between the lengthened length of the film 102 and the conveyor belt 1 -n 2 And time t.

An embodiment of the present application further provides a paper film laminating method for packaging a film 102, which is implemented based on the paper film laminating apparatus 100 provided in any one of the above embodiments.
As shown in fig. 11, the paper film laminating method includes the steps of:
s10: controlling the film feeding mechanism 10 to feed the film 102;
s20: controlling the first conveying mechanism 20 to receive and convey the thin film 102 conveyed by the film conveying mechanism 10;
s30: controlling the second conveying mechanism 30 to receive the film 102 conveyed by the first conveying mechanism 20 for conveying; wherein, along the conveying direction of the film 102, the second conveying mechanism 30 and the first conveying mechanism 20 are arranged at intervals to form an extended gap 35;
s40: controlling the ratio of the running speed between the second conveying mechanism 30 and the first conveying mechanism 20 based on the paper film laminating ratio, so that part of the thin film 102 conveyed by the first conveying mechanism 20 is accumulated in the extension gap 35;
s50: the paper board conveying mechanism 50 is controlled to convey the paper boards 101, the paper boards 101 are erected at the extended gaps 35, and the paper boards 101 are respectively overlapped with the films 102 on the first conveying mechanism 20 and the second conveying mechanism 30.
It can be understood that by controlling the running speeds of the first conveying mechanism 20 and the second conveying mechanism 30 to have a speed difference, for example, controlling the running speed of the second conveying mechanism 30 to be smaller than the running speed of the first conveying mechanism 20, the speed of the second conveying mechanism 30 for conveying the film 102 is slower during the process of conveying the film 102, so that part of the film 102 naturally sinks from the extension gap 35 and is accumulated in the extension gap 35, and the extension of the film 102 is realized, that is, the length ratio of the film 102 to the paperboard 101 is greater than 1:1; and the length of extension of the film 102 is determined by the speed difference between the first transfer mechanism 20 and the second transfer mechanism 30 and the running time. For another example, when the first conveying mechanism 20 and the second conveying mechanism 30 run at the same speed, the film 102 cannot be stacked, so that the ratio of the combined length of the paper board 101 and the film 102 is 1: the length ratio of the paper film lamination can be adjusted without stopping the machine in the paper film lamination process, so that the working efficiency is effectively improved, and the lamination process is simplified.
There is no clear sequence between steps S10-S50. For example, step S10 and step S20 may be performed simultaneously, and the ratio of the operating speeds of the first transmission mechanism 20 and the second transmission mechanism 30 may be set in advance in step S40 compared to step S10 and step S20.
Assume that the first conveying member 22 is operated at a speed V 1 ，T 1 The length L of the film 102 conveyed by the first conveying member 22 for the length of time the film 102 is conveyed by the first conveying member 22 1 Is L 1 =V 1 *T 1 The second conveying member 32 is operated at a speed V 2 ，T 2 The length L of the film 102 conveyed by the second conveying member 32 for the time period during which the film 102 is conveyed by the second conveying member 32 2 Is L 2 =V 2 *T 2 The lengthened length of the middle part of the film 102 is S, then S = V 1 *T 1 －V 2 *T 2 . As can be seen from the formula, the film 102 lengthening length S is related to the speed difference and time between the first conveying member 22 and the second conveying member 32. Therefore, the speed difference V between the first conveying member 22 and the second conveying member 32 in the unit time can be controlled in the embodiment 1 －V 2 To precisely control the extension length S, it is also possible to fix the speed difference between the first transfer member 22 and the second transfer member 32 by controlling the time or time difference T of the operation of the first transfer member and the second transfer member 1 －T 2 To precisely control the lengthening length S of the film 102, and to realize infinite lengthening of the film 102, for example, if the first conveying member 22 and the second conveying member 32 run for equal time t, the lengthening length S = (V) of the film 102 is achieved 1 －V 2 ) T. It should be noted that the time difference between the operations of the first conveyor 22 and the second conveyor 32 may be controlled, and for example, when the first conveyor 22 operates for 10 seconds and the second conveyor 32 stops operating for 5 seconds, the time difference between the first conveyor 22 and the second conveyor 32 may be controlled.

In one embodiment, step S30 specifically includes the following steps: s31: controlling the second transfer mechanism 30 to adsorb the film 102 transferred by the first transfer mechanism 20; s32: the second transfer mechanism 30 is controlled to move so that the adsorbed film 102 is transferred as the second transfer mechanism 30 operates. At this time, if there is a speed difference between the second conveyance mechanism 30 and the first conveyance mechanism 20, the film 102 drops and is stacked in the extension gap 35, and the extension of the film 102 is realized.

Specifically, the rotating member 61 is controlled to rotate by the fourth driving member, so that the third adsorption member 51 on the rotating member 61 is driven to rotate to the storage station A1 for storing the paper board 101, and then the telescopic unit 52 is controlled to extend, so that the third adsorption member 51 is driven to move downwards to be close to the paper board 101 and adsorb the cut paper board 101; the retractable unit 52 retracts to drive the third absorbing member 51 and the paper board 101 to return to the initial height position, the rotating member 61 continues to rotate to drive the paper board 101 to reach the gluing station for gluing, after the gluing is finished, the rotating member 61 continues to rotate until the paper board 101 is driven to reach the upper part of the extended gap 35, and then the third driving member and the retractable unit 52 are controlled to drive the paper board 101 to move downwards and erect on the extended gap 35, so that the film 102 is bonded with the glued part of the paper board 101.
