[0045] In the description of the utility model, it should be explained that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0046] As shown in Figures 1 to 4 In an embodiment, the pre-stripping module 51 is used to separate the cover film 11 of the film material 1 and the base paper 12 of the film material 1, wherein the cover film 11 covers the base paper 12. The pre-stripping module 51 comprises a stripping knife 511, a pre-stripping support frame 512 and a first pre-stripping driving assembly 514; the pre-stripping support frame 512 is connected to the first pre-stripping driving assembly 514; the stripping knife 511 is connected to the pre-stripping support frame 512 and can cause the base paper 12 to be bent; the first pre-stripping driving assembly 514 can drive the stripping knife 511 to reciprocate in the first direction, so that the stripping knife can apply force to the cover film 11 on the side of the base paper 12 away from the cover film 11 to separate the cover film 11 from the base paper 12, thereby facilitating the cover film module 3 to take away the cover film 11 from the base paper 12.

[0047] In Figure 1 And Figure 2 The first direction is parallel to the X axis in the direction shown. Wherein, the first direction can be the front-back direction.

[0048] When the first pre-stripping driving assembly 514 drives the stripping knife 511 to move in the first direction, the stripping knife 511 can be moved to the edge of the cover film 11. Since the base paper 12 is bent at the stripping knife 511, the stripping knife 511 can apply a force to the base paper 12 towards the cover film 11, thereby applying a force to the edge of the cover film 12 in the direction from the base paper 11 to the cover film 12, so that the edge of the cover film 12 is separated from the base paper, which is beneficial to reduce the adhesion between the cover film and the base paper, thereby facilitating the cover film module 3 to take away the cover film 11 from the base paper 12.

[0049] Moreover, during operation, the stripping knife 511 can be driven to move forward to the front edge of the cover film 11, then the stripping knife 511 is driven to reciprocate in the first direction to roll up the front edge of the cover film 11, so that the front edge of the cover film 11 is separated from the base paper 12, then the cover film 11 can be grabbed by the cover film module 3, then the stripping knife 511 is moved relative to the film material 1 from front to back until the stripping knife 511 reaches the rear edge of the cover film 11, during which the stripping knife 511 can continuously apply a force to the front edge of the area of the cover film 11 contacting the base paper 12, which is beneficial to separate the cover film 11 from the base paper 12, and during this process, the cover film module 3 can move forward or can not move.

[0050] Moreover, the movement of the stripping knife 511 relative to the film material 1 from front to back can mean that the film material is stationary and the stripping knife 511 moves from front to back, or the stripping knife 511 is stationary and the film material 1 moves from back to front (for example, the process of unwinding by the film material unwinding module and winding by the film material winding module), or the film material 1 moves from back to front and the stripping knife 511 moves from front to back.

[0051] The "pre-stripping module 51 is used to separate the cover film 11 of the film material 1 and the base paper 12 of the film material 1" can mean that the pre-stripping module 51 separates the edge of the cover film 11 and the base paper 12, or can mean that the pre-stripping module 51 cooperates with other devices (for example, the locking device 2 or the cover film module 3 described below) to separate the cover film and the base paper. This operation is equivalent to pre-separation of the cover film 11 and the base paper 12, and the pre-stripping module 51 will further cooperate with the cover film module 3 to completely separate the cover film 11 and the base paper 12 of the required length.

[0052] The "first pre-stripping driving assembly 514 drives the stripping knife 511 to reciprocate in the first direction" can mean that the first pre-stripping driving assembly 514 drives the pre-stripping support frame 512 to reciprocate in the first direction, thereby driving the stripping knife 511 to reciprocate in the first direction.

[0053] In addition, the first pre-stripping driving assembly 514 is connected to the rack to support the pre-stripping module 51 by the rack, and the rack can be placed on the ground.

[0054] When the pre-stripping module 51 is applied to the film laminating machine, the pre-stripping module 51 can cooperate with the locking device to separate the cover film and the base paper. The locking device 2 can lock or unlock the film material 1 on both sides in the first direction of the pre-stripping module 51. When the locking device 2 locks the film material 1, it can prevent the film material 1 from moving in the first direction; when the locking device 2 unlocks the film material 1, it can allow the film material 1 to move in the first direction for unwinding and winding.

[0055] In addition, "the locking device 2 locks the film material 1" means that the locking device 2 locks the film material 1 on both sides in the first direction of the pre-stripping module 51; at the same time, "the locking device 2 unlocks the film material 1" means that the locking device 2 unlocks the film material 1 on both sides in the first direction of the pre-stripping module 51.

[0056] When the pre-stripping module 51 is applied to the film laminating machine, it can cooperate with the film material unwinding module of the film laminating machine and the film material winding module of the film laminating machine, wherein the film material 1 is usually in the form of a roll, the film material unwinding module is used to unwind the film material 1 roll, and the film material winding module is used to wind the base paper 12. Moreover, the film material unwinding module and the film material winding module are arranged along the first direction and are spaced apart, and the pre-stripping module 51 is located between the two. The film material 1 unwound by the film material unwinding module will first pass through the stripping knife 511 and then reach the film material winding module. At this time, the cover film 11 on the film material 1 has been removed, and only the base paper 12 of the film material 1 reaches the film material winding module.

[0057] At this time, the locking device 2 can include the film material unwinding module and the film material winding module described above, so that the locking and unlocking of the film material 1 can be realized through the film material unwinding module and the film material winding module. Specifically, neither the film material unwinding module nor the film material winding module rotates, so that the film material 1 unwound will not move, and at this time the film material 1 can be regarded as being locked. Moreover, when the film material unwinding module and the film material winding module rotate for unwinding and winding, the film material 1 unwound can move along the first direction, thereby realizing the unlocking of the film material 1.

[0058] Reference Figure 4 In some embodiments, the locking device 2 can also be arranged in other ways. For example, the locking device 2 includes a first film material clamping module 21 and a second film material clamping module 22, and the pre-stripping module 51 is arranged between the first film material clamping module 21 and the second film material clamping module 22 in the first direction. The first film material clamping module 21 and the second film material clamping module 22 are both used to clamp or release the film material 1.

[0059] When it is necessary to lock the film material 1, the first film material clamping module 21 and the second film material clamping module 22 can clamp the film material 1 at the same time; when it is necessary to unlock the film material 1, the first film material clamping module 21 and the second film material clamping module 22 can release the film material 1 at the same time.

[0060] In addition, the stripping knife 511 reciprocates along the first direction while being kept between the first film material clamping module 21 and the second film material clamping module 22.

[0061] In addition, in the first direction, the first film material clamping module 21 and the second film material clamping module 22 are both located between the film material unwinding module and the film material winding module, and the first film material clamping module 21 is located between the film material unwinding module and the pre-stripping module 51, and the second film material clamping module 22 is located between the film material winding module and the pre-stripping module 51.

[0062] In an embodiment, the first film material clamping module 21 comprises a film clamping driving member, a first film clamping plate and a second film clamping plate, wherein the film clamping driving member is capable of driving at least one of the first film clamping plate and the second film clamping plate to move, so that the distance between the first film clamping plate and the second film clamping plate can be increased or decreased. When the distance between the first film clamping plate and the second film clamping plate is increased, the film material 1 between the first film clamping plate and the second film clamping plate can be released; when the distance between the first film clamping plate and the second film clamping plate is decreased, the film material 1 between the first film clamping plate and the second film clamping plate can be clamped.

[0063] In an embodiment, the film clamping driving member comprises a cylinder, the first film clamping plate is connected to the cylinder body of the cylinder, and the second film clamping plate is connected to the piston rod of the cylinder. The cylinder can drive the second film clamping plate to move, so that the second film clamping plate moves towards or away from the first film clamping plate, so as to clamp or release the film material 1 between the first film clamping plate and the second film clamping plate.

[0064] In addition, the cylinder can drive the second film clamping plate to move up and down, so that the second film clamping plate moves towards or away from the first film clamping plate. The first film clamping plate can be located below the second film clamping plate, or the first film clamping plate can be located above the second film clamping plate.

[0065] In addition, the second film material clamping module 22 and the first film material clamping module 21 are provided with the same structure. In addition, the first film material clamping module 21 and the second film material clamping module 22 can also be provided with other structures capable of clamping or releasing the film material 1 in the prior art, and the present embodiment does not make too many limitations.

[0066] It should be noted that the part of the film material 1 clamped by the first film material clamping module 21 has the cover film 11 and the base paper 12; and the part of the film material 1 clamped by the second film material clamping module 22 has the base paper 12, but does not have the cover film 11, that is, the second film material clamping module 22 actually clamps the base paper 12.

[0067] In the prior art, the cutting device of the film laminating machine also needs to lock the film 1 to ensure the cutting accuracy. Specifically, the film 1 needs to be locked on both sides in the first direction of the cutting device. In actual scenarios, the locking device 2 described above can be a device used in cooperation with the cutting device. The pre-stripping module 51 of the present application is equivalent to cooperating with the locking device 2 in the prior art to separate the film 1.

[0068] As shown in Figure 2 In an embodiment, the stripping knife 511 can be a triangular prism structure, and its cross section can be a right triangle or an isosceles triangle, etc. During operation, the base paper 12 can be bent at one of its edges. Of course, in other embodiments, the cross section of the stripping knife 511 can also be a prism structure of other shapes, or the stripping knife 511 can also be a cylindrical structure, etc.

[0069] In addition, the driving pre-stripping support frame 512 moves the stripping knife 511 to the edge of the cover film 11, mainly referring to the movement of the edge of the stripping knife 511 to the edge of the cover film 11.

[0070] As shown in Figure 1 In an embodiment, the pre-stripping module 51 further comprises a pre-stripping guide 513 connected to the pre-stripping support frame 512 and spaced apart from the stripping knife 511. The stripping knife 511 can bend the base paper 12 passing between the stripping knife 511 and the pre-stripping guide 513. In use, the base paper 12 can first pass around the stripping knife 511, then extend between the stripping knife 511 and the pre-stripping guide 513, and then pass around the pre-stripping guide 513, wherein the base paper 12 is bent into a Z shape by the stripping knife 511 and the pre-stripping guide 513.

[0071] In addition, in use, the base paper 12 with the cover film 11 can be manually passed between the stripping knife 511 and the pre-stripping guide 513, and the stripping knife 511 is located on the side of the base paper 12 away from the cover film 11, and the length of the base paper 12 is greater than the length of the cover film 11 (i.e. a part of the area of the base paper 12 is not covered by the cover film 11), so that when the base paper 12 is bent at the stripping knife 511, the cover film 11 can not be bent at the stripping knife 511. When the first pre-stripping driving assembly 514 drives the stripping knife 511 to move in the first direction, the stripping knife 511 can be moved to the edge of the cover film 11. Since the base paper 12 is bent at the stripping knife 511, the stripping knife 511 can exert a force on the base paper 12 towards the cover film 11, thereby exerting a force on the cover film 11 along the direction from the base paper 12 to the cover film 11, thereby facilitating the separation of the edge of the cover film 11 from the base paper 12.

[0072] In one embodiment, the pre-peeling guide 513 is rotatable about its own axis relative to the pre-peeling support 512; the axis of the pre-peeling guide 513 is parallel to the second direction. This reduces friction between the pre-peeling guide 513 and the film 1.

[0073] The pre-stripping guide 513 can be a cylindrical structure with pre-stripping support frame 512 connected to both ends.

[0074] Additionally, the pre-stripping guide 513 can be located below the stripper 511, with the two spaced apart in the vertical direction. Figure 1 and Figure 2 In the directions shown, the vertical direction is parallel to the Z-axis. At this time, the film material 1 can be bent downwards at the peeling blade 511 to wrap around the pre-peeling guide 513. Wherein, Figure 4 In the direction shown, the film material extends forward (i.e., along the direction of the arrow on the X-axis), bends downward at the front end of the peeling blade 511, and wraps around the pre-peeling guide 513. After wrapping around the pre-peeling guide 513, the film material 1 (actually the backing paper 12) continues to extend forward.

[0075] like Figure 1 As shown, in one embodiment, multiple pre-peeling guides 513 are provided, and the multiple pre-peeling guides 513 are arranged sequentially and spaced apart below the peeling blade 511 in a vertical direction. When the backing paper 12 passes between the peeling blade 511 and the different pre-peeling guides 513, the bending angle of the backing paper 12 is different. This allows the bending angle of the backing paper 12 to be adjusted according to actual needs, improving the separation effect between the cover film 11 and the backing paper 12.

[0076] Among them, Figure 1 In the example shown, there are two pre-stripping guides 513.

[0077] Furthermore, the first direction, the second direction, and the up / down direction are all perpendicular to each other. In this case, the first direction can be front / back, and the second direction can be left / right. Figure 1 and Figure 2 Of the directions shown, the second direction is parallel to the Y-axis, while the X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0078] In one embodiment, the first pre-peeling drive component 514 may be a drive system composed of components such as a rotary motor, a lead screw transmission mechanism, and a guide mechanism, capable of driving the linear motion of an object; or, the first pre-peeling drive component 514 may also be a device such as a linear motor capable of driving the linear motion of an object.

[0079] like Figure 1 and Figure 2As shown, in one embodiment, the pre-peeling module 51 further includes a pre-peeling platform 515, which is disposed on the pre-peeling support frame 512; the pre-peeling platform 515 and the peeling blade 511 are arranged along a first direction; the pre-peeling platform 515 is used to support and place the film material 1. This can improve the support effect on the film material 1.

[0080] Furthermore, the pre-peeling platform 515 is also used in conjunction with the cutting device, so that the cutting device can cut the cover film 11 of the film material 1 placed on the pre-peeling platform 515, so that the film coating module 3 can take away the cover film 11 of the required length.

[0081] like Figure 1 As shown, in one embodiment, the pre-peeling platform 515 has a pre-peeling support surface 5151, and the film material 1 placed on the pre-peeling platform 515 is actually placed on the pre-peeling support surface 5151.

[0082] In some scenarios, the pre-peeling support surface 5151 is the upper surface of the pre-peeling platform 515. Moreover, the pre-peeling support surface 5151 can be a plane. At the same time, when the module is placed on the pre-peeling support surface 5151, the backing paper 12 of the portion of the film material 1 located on the pre-peeling support surface 5151 can be located between the cover film 11 of that portion of the film material 1 and the pre-peeling support member 51b2.

[0083] In the embodiment where the peeling blade 511 is a triangular prism, one side of the peeling blade 511 may be flush with the pre-peeling support surface 5151. The other sides of the peeling blade 511 and the two end faces in the axial direction are all located below this side. In use, the backing paper 12 passes around the edge of the triangular prism from this side.

[0084] like Figure 1 and Figure 2 As shown, in one embodiment, the pre-peeling module 51 further includes a first pre-peeling pressing member 516 and a pre-peeling pressing drive member 517; the pre-peeling pressing drive member 517 is connected to the pre-peeling support frame 512 and connected to the first pre-peeling pressing member 516; the pre-peeling pressing drive member 517 is used to drive the first pre-peeling pressing member 516 so that the first pre-peeling pressing member 516 can cooperate with the pre-peeling platform 515 to clamp or release the film material 1 placed on the pre-peeling platform 515.

[0085] When the pre-peeling module 51 is applied to the laminating machine, the film material 1 unwound by the unwinding module of the film unwinding device will be placed on the pre-peeling platform 515. During operation, after the unwinding module of the film unwinding device unwinds a certain length of film material 1, the pre-peeling pressing drive 517 can drive the first pre-peeling pressing component 516 to approach the pre-peeling platform 515 in order to clamp the film material 1. Then, the first pre-peeling drive assembly 514 can drive the pre-peeling support frame 512 to move a predetermined distance along the first direction. Then, the cutting device cuts the cover film 11, so that the length of the cut film unit meets the requirements.

[0086] In the prior art, the length of the film material 1 unwound is usually calculated by the number of turns of the unwinding module of the film material unwinding device, and then used as the basis for the length of the film unit cut by the cutting device. However, as the unwinding operation proceeds, the diameter of the film material 1 roll continuously decreases, and the length of the film material 1 unwound per turn also continuously decreases, so there is an error in calculating the length of the film unit. The arrangement of the present embodiment can more accurately calculate the length of the film material 1 unwound, thereby improving the accuracy of the length of the film unit cut.

[0087] In addition, the cutting position of the cutting device can be located between the first pre-stripping pressing piece 516 and the stripping knife 511.

[0088] In an embodiment, in the first direction, the stripping knife 511 can be located between the pre-stripping platform 515 and the winding module of the film material winding device, and the first pre-stripping pressing piece 516 can be located between the stripping knife 511 and the unwinding module of the film material unwinding device. Moreover, in the first direction, the first pre-stripping pressing piece 516 is arranged spaced apart from the stripping knife 511.

[0089] In an embodiment, the first pre-stripping pressing piece 516 can be a pressing plate, and the pre-stripping pressing drive 517 can be a pneumatic cylinder. The first pre-stripping pressing piece 516 presses the film material 1 against the pre-stripping platform 515, which actually means that the first pre-stripping pressing piece 516 presses the film material 1 against the pre-stripping support surface 5151.

[0090] Of course, in other embodiments, the pre-stripping pressing drive 517 can also be an electric cylinder or other device capable of driving the first pre-stripping pressing piece 516 to move linearly.

[0091] In an embodiment, the first pre-stripping pressing piece 516 is located above the pre-stripping platform 515, the pre-stripping pressing drive 517 is located below the pre-stripping platform 515 and is used to drive the first pre-stripping pressing piece 516 to move up and down, and the first direction is perpendicular to the up-down direction. This makes it more convenient to install and arrange the pre-stripping module 51, which is conducive to reducing the space occupied by the pre-stripping module 51.

[0092] In addition, the pre-stripping platform 515 can be provided with a relief hole, and the pre-stripping pressing drive 517 can pass through the pre-stripping platform 515 from the relief hole to connect the first pre-stripping pressing piece 516.

[0093] In an embodiment, the pre-stripping module 51 can include two pre-stripping pressing drives 517, which can be arranged spaced apart along the second direction and used to simultaneously drive the first pre-stripping pressing piece 516 to move. In operation, the film material 1 can pass between the two pre-stripping pressing drives 517.

[0094] AsFigure 1 and Figure 2 As shown, in one embodiment, the pre-peeling module 51 further includes a pre-peeling air blowing assembly 518, which is connected to the pre-peeling support frame 512 and is capable of blowing up the cover film 11 on the base paper 12 bent by the peeling blade 511. Specifically, the pre-peeling air blowing assembly can blow air onto the cover film 11 on the base paper 12 that has passed through the peeling blade 511 along the direction from the pre-peeling guide 513 to the peeling blade 511. This arrangement facilitates the separation of the cover film 11 from the base paper 12.

[0095] like Figure 2 As shown, in one embodiment, the pre-peeling air blowing assembly 518 includes an air outlet pipe 5181, which is used to connect to the source and to blow air onto the film material 1. In a first direction, the air outlet pipe 5181 is located between the peeling blade 511 and the unwinding module of the film material unwinding device; in the vertical direction, the air outlet pipe 5181 is located below the peeling blade 511; the air outlet pipe 5181 extends along a second direction and is provided with an air outlet hole, through which gas in the air outlet pipe 5181 can flow out and blow the cover film 11.

[0096] Specifically, the air outlet extends from the outer side of the air outlet pipe 5181 to the inner surface of the air outlet pipe 5181.

[0097] In one embodiment, there may be multiple air outlets, which are spaced apart along the length of the air outlet duct 5181. Alternatively, the air outlets may be elongated slot structures that extend along the length of the air outlet duct 5181.

[0098] like Figure 2 and Figure 3 As shown, in one embodiment, the pre-peeling module 51 further includes a second pre-peeling drive assembly 519 and a pre-peeling drive roller 51a; the second pre-peeling drive assembly 519 and the pre-peeling drive roller 51a are both connected to the pre-peeling support frame 512; the second pre-peeling drive assembly 519 is used to drive the pre-peeling drive roller 51a to rotate, so that the pre-peeling drive roller 51a can drive the film material 1 wrapped on the pre-peeling drive roller 51a.

[0099] The second pre-peeling drive assembly 519 driving the pre-peeling drive roller 51a to rotate actually means that the second pre-peeling drive assembly 519 provides driving force to the pre-peeling drive roller 51a, enabling the pre-peeling drive roller 51a to rotate around its own axis.

[0100] In addition, the axis of the pre-peeling drive roller 51a can be parallel to the second direction.

[0101] During operation, the backing paper 12 can be wound around the pre-peeling drive roller 51a. When the pre-peeling drive roller 51a rotates, it can increase the driving force for unwinding the film 1, and it can also accelerate the separation of the cover film 11 and the backing paper 12.

[0102] In one embodiment, the second pre-peeling drive assembly 519 may include a rotary motor and a synchronous belt drive mechanism. The cylinder of the rotary motor may be connected to the pre-peeling support frame 512, and the motor shaft of the rotary motor may be connected to the driving pulley of the synchronous belt drive mechanism. The driven pulley of the synchronous belt drive mechanism may be connected to the pre-peeling drive roller 51a. In this way, the driving force of the rotary motor can be transmitted to the pre-peeling drive roller 51a through the synchronous belt drive mechanism, thereby driving the pre-peeling drive roller 51a to rotate.

[0103] Of course, in other embodiments, the second pre-peeling drive assembly 519 may include a rotary motor but not a synchronous belt drive mechanism. In this case, the motor shaft of the rotary motor may be directly connected to the pre-peeling drive roller 51a. Furthermore, in other embodiments, the rotary motor may be connected to the pre-peeling drive roller 51a via a speed reducer or the like.

[0104] In one embodiment, the pre-peeling drive roller 51a is located below the peeling blade 511 and on the side of the peeling blade 511 close to the pre-peeling platform 515. Specifically, in the first direction, the pre-peeling drive roller 51a may be located between the peeling blade 511 and the first pre-peeling pressing member 516. Furthermore, in the first direction, the rotation motor of the second pre-peeling drive assembly 519 may be located between the pre-peeling drive roller 51a and the first pre-peeling pressing member 516.

[0105] like Figure 3 As shown, in one embodiment, the pre-peeling module 51 further includes a third pre-peeling drive assembly 51b and a second pre-peeling pressing member 51c; the third pre-peeling drive assembly 51b is connected to the pre-peeling support frame 512 and connected to the second pre-peeling pressing member 51c; the third pre-peeling drive assembly 51b is used to drive the second pre-peeling pressing member 51c closer to or further away from the pre-peeling drive roller 51a, so that the second pre-peeling pressing member 51c and the pre-peeling drive roller 51a can clamp or release the backing paper 12. This arrangement can improve the driving force of the pre-peeling drive roller 51a on the film material 1.

[0106] In one embodiment, in the first direction, the second pre-peeling pressing member 51c is located on the side of the pre-peeling drive roller 51a away from the peeling knife 511, and the third pre-peeling drive assembly 51b can drive the second pre-peeling pressing member 51c to reciprocate along the first direction, so that the second pre-peeling pressing member 51c can move closer to or further away from the pre-peeling drive roller 51a.

[0107] When the second pre-peeling pressing member 51c approaches the pre-peeling drive roller 51a, the second pre-peeling pressing member 51c and the pre-peeling drive roller 51a can clamp the bottom paper 12 located between them; when the second pre-peeling pressing member 51c moves away from the pre-peeling drive roller 51a, the second pre-peeling pressing member 51c and the pre-peeling drive roller 51a can release the bottom paper 12 located between them.

[0108] In one embodiment, the second pre-peeling pressing member 51c is rotatable about its own axis relative to the third pre-peeling driving assembly 51b; the axis of the second pre-peeling pressing member 51c is parallel to the axis of the pre-peeling driving roller 51a and parallel to the second direction. This can reduce the frictional force between the second pre-peeling pressing member 51c and the backing paper 12. The third pre-peeling driving assembly 51b may be a cylindrical structure.

[0109] like Figure 3 As shown, in one embodiment, the third pre-peeling drive assembly 51b includes a pre-peeling drive member 51b1 and a pre-peeling support member 51b2. The pre-peeling drive member 51b1 is connected to the pre-peeling support frame 512 and the pre-peeling support member 51b2. The second pre-peeling pressing member 51c is connected to the pre-peeling support member 51b2. The pre-peeling drive member 51b1 drives the pre-peeling support member 51b2 to move, thereby driving the second pre-peeling pressing member 51c to move.

[0110] In one embodiment, the pre-peeling drive member 51b1 is a pre-peeling drive cylinder, the pre-peeling support member 51b2 is a pre-peeling support block, and the second pre-peeling pressing member 51c may be rotatably connected to the pre-peeling support block. Furthermore, there are two pre-peeling drive members 51b1 and two pre-peeling support members 51b2, with each pre-peeling drive member 51b1 connecting to its corresponding pre-peeling support member 51b2. The two ends of the second pre-peeling pressing member 51c are respectively connected to the two pre-peeling support members 51b2.

[0111] like Figure 1 and Figure 2 As shown, in one embodiment, the pre-peeling support frame 512 includes a first pre-peeling support plate 5121, a second pre-peeling support plate 5122, and a third pre-peeling support plate 5123; the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122 are spaced apart along a second direction and are both connected to the first pre-peeling drive assembly 514; the two ends of the third pre-peeling support plate 5123 are respectively connected to the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122, and the peeling blade 511 and the pre-peeling guide 513 can both be connected to the third pre-peeling support plate 5123.

[0112] Furthermore, the two ends of the pre-peeling platform 515 are respectively connected to the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122, and are located above the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122. The second pre-peeling drive assembly 519 is located below the pre-peeling platform 515. Moreover, after assembly, the third pre-peeling support plate 5123 can also be located below the pre-peeling platform 515.

[0113] The second pre-stripping driving assembly 519, the third pre-stripping driving assembly 51b and the pre-stripping driving roller 51a can be connected to any one of the first pre-stripping support plate 5121 and the second pre-stripping support plate 5122.

[0114] In addition, the pre-stripping pressing driving member 517 can be located between the first pre-stripping support plate 5121 and the second pre-stripping support plate 5122, so as to be shielded by the first pre-stripping support plate 5121 and the second pre-stripping support plate 5122. When the pre-stripping pressing driving member 517 can be not arranged between the first pre-stripping support plate 5121 and the second pre-stripping support plate 5122.

[0115] The utility model embodiment further provides a film sticking machine, the film sticking machine includes locking device 2 and the pre-stripping module described in any one embodiment, locking device 2 can lock or unlock film material 1 on both sides of the first direction of pre-stripping module.

[0116] In addition, the film sticking machine further includes a rack, and the locking device 2 and the pre-stripping module are arranged on the rack.
