Description

Technical Field

[0001] The present invention relates to the technical field of sheet material film laminating equipment, and particularly relates to a double-sided film laminating device for flat sheet materials and film materials. Background Art

[0002] The double-sided film laminating process for sheet materials is to press the vertically arranged sheet material downward to the center of the horizontally placed film material and pass through a pair of pressure rollers to achieve double-sided film lamination of the sheet material. Before performing the film laminating function, it is necessary to clamp the lower end of the sheet material to move the whole sheet material and film material, so that the lower ends of the sheet material and film material move between a pair of pressure rollers, and then move a pair of pressure rollers to press the film material on both sides of the sheet material. The above actions need to be completed in two working beats. The inventor believes that the above action control is complex and the working efficiency is not high, which needs to be improved. Summary of the Invention

[0003] To overcome the deficiencies of the above prior art, the present invention provides a double-sided film laminating device for flat sheet materials and film materials, which realizes the linkage movement of the moving seat and the sliding seat and improves the production efficiency.

[0004] To achieve the above object, the present invention is realized by the following technical solutions:

[0005] A double-sided film laminating device for flat sheet materials and film materials, comprising

[0006] a frame, on which a film material placement plate is provided, and a slot is provided in the center of the film material placement plate,

[0007] a conveying module, the conveying module includes a moving seat and a first driving device for driving the moving seat to move in the vertical direction, and a clamping device is provided on the moving seat;

[0008] a film pressing assembly, the film pressing assembly includes a pair of sliding seats, the sliding seats are horizontally slidably arranged on the frame, the pair of sliding seats are arranged on both sides below the slot, the pair of sliding seats are symmetrically arranged on both sides of the moving seat, a roller body driven by rotation is provided on the sliding seat, a transmission connecting rod is rotatably connected to the sliding seat, and the end of the transmission connecting rod away from the sliding seat is rotatably arranged on the moving seat;

[0009] The clamping device is used for clamping the bottom of the sheet material inserted into the slot, and the first driving device is used for driving the moving seat to move downward to the position where the material to be film laminated is at the same height as the center of the roller body. Due to the transmission connection of the transmission connecting rod, the pair of sliding seats move synchronously in the horizontal direction to make the pair of roller bodies fit on both sides of the material.

[0010] Based on the above structure, when a double-sided film laminating device for flat sheet materials and film materials is used, it includes the following steps:

[0011] S1. Lay the flat film material flat on the film material placement plate. There is a groove preset in the center of the flat film material, and the groove is aligned with the insertion slot. The lower end of the sheet material is provided with an extension plate passing through the groove. On both sides of the proximal end of the extension plate (i.e., the end of the extension plate close to the sheet material), there is a pair of bottom edges. The sheet material is vertically placed above the insertion slot. The extension plate penetrates into the groove from top to bottom so that the bottom edges are attached to the upper end of the flat film material. At this time, the extension plate penetrates into the insertion slot.

[0012] S2. Clamp the bottom of the sheet material through the clamping device.

[0013] S3. The first driving device is used to drive the moving seat to move downward to the position where the material to be coated with film is located, that is, the height of the proximal end of the extension plate is the same as the center height of the roller body. At this time, the pair of sliding seats move synchronously in the horizontal direction relative to each other until the pair of roller bodies are attached to both sides of the sheet material, and the lower end of the flat film material is pressed on the sheet material.

[0014] S4. The clamping device releases the sheet material.

[0015] S5. Rotate to drive the pair of roller bodies. The rotation directions of the pair of roller bodies are opposite. The pair of roller bodies press the film materials on both sides of the groove on both sides of the sheet material respectively, and at the same time push the sheet material with the film coated downward. After the sheet material and the flat film material completely pass through the pair of roller bodies, the flat film material adheres to both sides of the sheet material.

[0016] Furthermore, in a double-sided film coating device for flat sheet film materials in the present application, the first driving device is a driving cylinder. The fixed component of the driving cylinder is installed on the frame, and the movable component of the driving cylinder is connected to one of the sliding seats. The driving cylinder is used to drive the sliding seat to move horizontally. As a preferred solution of the present application, the driving cylinder is arranged horizontally as a whole, and drives the horizontal movement of the sliding seat to drive the moving seat to move vertically synchronously.

[0017] Furthermore, in a double-sided film coating device for flat sheet film materials in the present application, the hinge point of the transmission connecting rod at one end of the sliding seat is the rotation axis core of the roller body, and the position of the hinge point of the transmission connecting rod at one end of the sliding seat is obliquely above the hinge point on the moving seat.

[0018] Furthermore, in a double-sided film coating device for flat sheet film materials in the present application, there is a positioning block between the pair of sliding seats. When the pair of sliding seats move horizontally in the opposite direction, they are finally limited to both sides of the positioning block. At this time, the pair of roller bodies are attached to both sides of the material. As a preferred solution of the present application, the positioning block is used to limit the movement of the pair of sliding seats in the opposite direction.

[0019] Furthermore, a double-sided film laminating device for flat sheet material in the present application further includes a set of right-angle positioning blocks. The right-angle positioning blocks are arranged on the material placing plate. The set of right-angle positioning blocks respectively correspond to the 4 right angles of the rectangular placing area on the material placing plate, and the right-angle contour of the right-angle positioning blocks linearly increases from bottom to top. As a preferred solution of the present application, the right-angle positioning blocks are used to position the four corners of the flat sheet material placed on the material placing plate. The right-angle contour of the right-angle positioning blocks linearly increases from bottom to top, which is convenient for placing the flat sheet material from top to bottom into the placing cavity formed by the right-angle positioning blocks.

[0020] Furthermore, a double-sided film laminating device for flat sheet material in the present application further includes a pressing wheel assembly, and the pressing wheel assembly includes:

[0021] A pressing wheel frame is arranged outside the material placing plate. An installation rod is rotatably arranged on the pressing wheel frame, and the front end of the installation rod extends towards the material placing area of the material placing plate;

[0022] A pressing wheel is rotatably installed at the front end of the installation rod, and the radial cross-section of the outer edge of the pressing wheel is arc-shaped;

[0023] The pressing wheel assemblies are arranged in pairs on both sides of the material placing plate.

[0024] During use, by rotating the installation rod, the pressing wheel is pressed against the upper end of the flat sheet material. The rotation direction of the pressing wheel corresponds to the moving direction of the flat sheet material on the material placing plate, ensuring that the flat sheet material is attached to the material placing plate before entering the insertion slot and preventing the flat sheet material from warping or wrinkling during movement. Furthermore, in a double-sided film laminating device for flat sheet material in the present application, the pressing wheel frame includes a hinge seat, the installation rod is arranged on the hinge seat, the pressing wheel frame further includes a locking seat, the locking seat is arranged on the side of the hinge seat close to the material placing plate, an arc-shaped groove is provided on the locking seat, the center of the arc-shaped groove is the same as that of the hinge seat, and the arc-shaped groove axially penetrates through the upper end and is open;

[0025] It further includes a locking component, and the locking component is used to lock the installation rod in the arc-shaped groove.

[0026] The installation rod is rotated upwards out of the outside of the arc-shaped groove to place the flat sheet material on the material placing plate. Subsequently, the installation rod is rotated into the range of the arc-shaped groove and pressed above the flat sheet material, and the installation rod is locked to the arc-shaped groove through the locking component to ensure the stability of the pressing wheel pressing on the flat sheet material.

[0027] Further, in a double-sided laminating device for flat sheet film materials in the present application, the roller body is a hot pressing roller. As a preferred solution of the present application, the hot pressing laminating process is adopted to realize the lamination of the flat film material and the sheet material. A hot melt adhesive material is attached to the sides of the flat film material and the sheet material to be laminated, so as to avoid using a room temperature adhesive layer. When the flat film material passes through the slot, there is a risk of lamination between the flat film material and the sheet material.

[0028] Further, in a double-sided laminating device for flat sheet film materials in the present application, a vertically penetrating cavity is provided on the moving seat. The cavity is located below the slot and is directly opposite to the slot. A positioning tongue is movably provided on the moving seat. The positioning tongue is driven by a second driving device, and the second driving device is used to drive the positioning tongue to move so that the positioning tongue extends into or out of the cavity.

[0029] In the initial state, the moving seat moves to the highest position. The sheet material is vertically placed on the film material placing plate. The lower end of the sheet material passes through the slot and enters the cavity. The positioning tongue is used to position the lower end of the sheet material. A pair of limiting notches are clamped on the edges on both sides of the sheet material to perform horizontal positioning on the vertically placed sheet material. Before the sheet material moves relative to the moving seat, the second driving device drives the positioning tongue out of the cavity. Specifically, the second driving device is a first air cylinder. The first air cylinder is horizontally arranged, and the positioning tongue is arranged at the front end of the first air cylinder.

[0030] Further, in a double-sided laminating device for flat sheet film materials in the present application, the clamping device includes a chuck and a clamping plate respectively arranged on both sides of the cavity. The chuck is driven to move by a driving device so that the chuck moves towards the near side or the far side of the clamping plate. During the process of the chuck moving towards the near side of the clamping plate, it can clamp the sheet material positioned above the positioning tongue. As a preferred solution of the present application, the clamping device clamps the lower end of the sheet material between the chuck and the clamping plate. When the chuck and the positioning tongue both move out of the outside of the cavity, the sheet material can move downward out of the cavity.

[0031] From the above technical solutions, it can be seen that the present invention has the following beneficial effects:

[0032] The present invention provides a double-sided laminating device for flat sheet film materials. By realizing the linkage movement of the moving seat and the sliding seat through the transmission connecting rod, the synchronous operation of the vertical positioning of the sheet material and the horizontal positioning of the roller body is realized, and an overall driving device is used, so the manufacturing cost is reduced and the production efficiency is improved.

[0057] Combined with Figure 1 、 2 A double-sided film laminating device shown, including

[0058] Frame 1, on which a film material placement plate 14 is provided, and a slot 141 is provided at the center of the film material placement plate 14;

[0059] Figure 6 The conveying module shown, the conveying module includes a moving seat 21 and a first driving device for driving the moving seat 21 to move in the vertical direction, and a clamping device is provided on the moving seat 21;

[0060] The film pressing assembly 3 includes a pair of sliding seats 32 which are horizontally slidably arranged on the frame 1. The pair of sliding seats 32 are arranged on both sides below the insertion slot 141. The pair of sliding seats 32 are symmetrically arranged on both sides of the moving seat 21. A roller body 31 driven to rotate is provided on the sliding seat 32. A transmission connecting rod 33 is rotatably connected to the sliding seat 32. One end of the transmission connecting rod 33 far from the sliding seat 32 is rotatably arranged on the moving seat 21;

[0061] The clamping device is used to clamp the bottom of the sheet material 9 inserted into the insertion slot 141. The first driving device is used to drive the moving seat 21 to move downward to the position where the material to be covered with film is located, and the center height of the roller body 31 is the same. Due to the transmission connection of the transmission connecting rod 33, the pair of sliding seats 32 move synchronously and relatively in the horizontal direction until the pair of roller bodies 31 are attached to both sides of the material.

[0062] The double-sided film covering process for the sheet material is to press the vertically arranged sheet material down onto the center of the horizontally placed film material and pass it through a pair of pressure rollers to achieve double-sided film covering of the sheet material. Before performing the film covering function, it is necessary to clamp the lower end of the sheet material to move the sheet material and the film material as a whole, so that the lower ends of the sheet material and the film material move between the pair of pressure rollers, and then move the pair of pressure rollers to press the film material on both sides of the sheet material. The above actions need to be completed in two working beats. The inventor believes that the above action control is complex and the working efficiency is not high, which needs to be improved.

[0063] Based on the above structure, when a flat sheet material film covering device is used, it includes the following steps:

[0064] S1. Lay the flat film material 8 on the film material placing plate 14. A groove portion 81 is preset in the center of the flat film material 8. The groove portion 81 is aligned with the insertion slot 141. An extension plate 91 is provided at the lower end of the sheet material 9 and passes through the groove portion 81. A pair of bottom edges 92 are provided on both sides of the sheet material 9 corresponding to the proximal end of the extension plate 91 (i.e., the end of the extension plate 91 close to the sheet material 9). The sheet material 9 is vertically placed above the insertion slot 141. The extension plate 91 penetrates into the groove portion 81 from top to bottom so that the bottom edges 92 are attached to the upper end of the flat film material 8. At this time, the extension plate 91 penetrates into the insertion slot 141;

[0065] S2. As shown in Figure 16 Clamp the bottom of the sheet material 9 through the clamping device;

[0066] S3. As shown in Figure 17 The first driving device is used to drive the moving seat 21 to move downward to the position where the material to be covered with film is located, that is, the proximal end of the extension plate 91 is at the same center height as the roller body 31. At this time, the pair of sliding seats 32 move synchronously and relatively in the horizontal direction until the pair of roller bodies 31 are attached to both sides of the sheet material 9, and the lower end of the flat film material 8 is pressed on the sheet material 9;

[0067] S4. The clamping device releases the sheet material 9;

[0068] S5. As shown inFigure 18 As shown, a pair of roller bodies 31 are rotated and driven. The rotation directions of the pair of roller bodies 31 are opposite. The pair of roller bodies 31 press the film materials on both sides of the groove portion 81 against both sides of the sheet material 9 respectively, and at the same time push the sheet material 9 with the film attached downward. After the sheet material 9 and the flat film material 8 completely pass through the pair of roller bodies 31, the flat film material 8 adheres to both sides of the sheet material 9.

[0069] Therefore, in a double-sided film laminating device for flat sheet film materials of the present application, the transmission connecting rod 33 is used to realize the linkage movement of the moving seat 21 and the sliding seat 32, so as to realize the synchronous operation of the vertical positioning of the sheet material 9 and the horizontal positioning of the roller body 31. And the whole uses one driving device, so the manufacturing cost is reduced and the production efficiency is improved.

[0070] In this embodiment, the first driving device is a driving cylinder 4. The fixed component of the driving cylinder 4 is installed on the frame 1, and the movable component of the driving cylinder 4 is connected to one of the sliding seats 32. The driving cylinder 4 is used to drive the sliding seat 32 to move horizontally. The driving cylinder 4 is horizontally arranged on the outside of the sliding seat 32 as a whole, and drives the horizontal movement of the sliding seat 32 to drive the synchronous vertical movement of the moving seat 21. In other embodiments, the driving cylinders 4 are arranged in pairs and drive a pair of sliding seats 32 synchronously respectively.

[0071] In this embodiment, the hinge point of the transmission connecting rod 33 at one end of the sliding seat 32 is the rotation axis core of the roller body 31, and the position of the hinge point of the transmission connecting rod 33 at one end of the sliding seat 32 is obliquely above the hinge point on the moving seat 21.

[0072] In this embodiment, as Figure 6 shown, a positioning block 321 is arranged between a pair of sliding seats 32. When the pair of sliding seats 32 move horizontally in the opposite direction, they are finally limited to both sides of the positioning block 321. At this time, the pair of roller bodies 31 are attached to both sides of the material. The positioning block 321 is used to limit the movement of the pair of sliding seats 32 in the opposite direction. In this embodiment, a top plate 3211 is arranged at the upper end of the positioning block 321. The top plate 3211 is fixed on the sliding seat 32, and the positioning block 321 extends to the front end of the sliding seat 32. The positioning block 321 is arranged on the sliding seat 32 on the side close to the driving cylinder 4.

[0073] As Figure 3 shown, in this embodiment, it further includes a group of right-angle positioning blocks 142. The right-angle positioning blocks 142 are arranged on the film material placing plate 14. The group of right-angle positioning blocks 142 respectively correspond to the 4 right angles of the rectangular placing area on the film material placing plate 14. The right-angle contour of the right-angle positioning blocks 142 linearly increases from bottom to top. The right-angle positioning blocks 142 are used to position the four corners of the flat film material 8 placed on the film material placing plate 14. The right-angle contour of the right-angle positioning blocks 142 linearly increases from bottom to top, which is convenient for putting the flat film material 8 into the placing cavity formed by the right-angle positioning blocks 142 from top to bottom.

[0074] AsFigure 4 and 5 As shown in 5 , in this embodiment, it further includes a pressing wheel assembly 15, and the pressing wheel assembly 15 includes:

[0075] A pressing wheel frame 152 is arranged outside the film placing plate 14. A mounting rod 153 is rotatably arranged on the pressing wheel frame 152, and the front end of the mounting rod 153 extends towards the film placing area of the film placing plate 14;

[0076] A pressing wheel 151 is rotatably mounted at the front end of the mounting rod 153, and the radial cross-section of the outer edge of the pressing wheel 151 is arc-shaped;

[0077] The pressing wheel assemblies 15 are arranged in pairs on both sides of the film placing plate 14.

[0078] During use, the pressing wheel 151 is pressed against the upper end of the flat film material 8 by rotating the mounting rod 153. The rotation direction of the pressing wheel 151 corresponds to the moving direction of the flat film material 8 on the film material placing plate 14, ensuring that the flat film material 8 is attached to the film material placing plate 14 before entering the slot 141, and preventing the flat film material 8 from warping or wrinkling during movement. In this embodiment, when the pressing wheel 151 is pressed on the flat film material 8, the rotation axis core of the pressing wheel 151 is parallel to the film material placing plate 14 and perpendicular to the moving direction of the flat film material 8 on the film material placing plate 14. Specifically, the radial cross-section of the outer edge of the pressing wheel 151 is semi-circular. Two pairs of pressing wheel assemblies 15 are provided on each side of the slot 141. To prevent the pressing wheel 151 from leaving marks on the flat film material 8, the flat film material 8 is wider than the transverse dimension of the sheet material 9 in the width direction, and the pressing wheel 151 presses on the part of the flat film material 8 that extends beyond the outer edge of the sheet material 9. In this embodiment, the pressing wheel frame 152 includes a hinge seat 1521, the mounting rod 153 is arranged on the hinge seat 1521, the pressing wheel frame 152 further includes a locking seat 1522, the locking seat 1522 is arranged on the side of the hinge seat 1521 close to the film material placing plate 14, an arc-shaped groove 1520 is provided on the locking seat 1522, the center of the arc-shaped groove 1520 coincides with that of the hinge seat 1521, and the arc-shaped groove 1520 axially penetrates through the upper end opening; it further includes a locking component for locking the mounting rod 153 in the arc-shaped groove 1520. Rotate the mounting rod 153 upward out of the outside of the arc-shaped groove 1520 to place the flat film material 8 on the film material placing plate 14. Subsequently, rotate the mounting rod 153 into the range of the arc-shaped groove 1520, press it above the flat film material 8, and lock the mounting rod 153 on the arc-shaped groove 1520 through the locking component to ensure the stability of the pressing wheel 151 pressing on the flat film material 8. In this embodiment, the locking component includes a limit screw 154 and a locking nut 155. The limit screw 154 is installed on the mounting rod 153, the radial dimension of the limit screw 154 is adapted to the width of the arc-shaped groove 1520, and the locking nut 155 is arranged at the front end of the mounting rod 153; when the mounting rod 153 rotates into the range of the arc-shaped groove 1520, the limit screw 154 axially penetrates through the arc-shaped groove 1520, and at this time, tighten the locking nut 155, and the mounting rod 153 can be locked on the arc-shaped groove 1520. Specifically, the locking seats 1522 are arranged in pairs on both sides of the mounting rod 153. When locking, a pair of locking seats 1522 are respectively clamped between the screw head of the limit screw 154 and the mounting rod 153 and between the mounting rod 153 and the locking nut 155.

[0079] In this embodiment, the roller body 31 is a hot pressing roller. The hot pressing film laminating process is adopted to realize the lamination of the flat film material 8 and the sheet material 9. A hot melt adhesive material is attached to the side surfaces of the flat film material 8 and the sheet material 9 to be laminated to avoid using a normal temperature adhesive layer. When the flat film material 8 passes through the slot 141, there is a risk of lamination between the flat film material 8 and the sheet material 9. Specifically, the hot melt adhesive material can be selected as hot melt TPU.

[0080] As Figure 7 and 8 shown, in this embodiment, the moving seat 21 includes a pair of clamping plates 211 arranged at intervals and a pair of connecting plates 212. The cavity 210 is arranged between the pair of clamping plates 211. The pair of connecting plates 212 are arranged at both ends of the clamping plates 211, and the connecting plates 212 connect the pair of clamping plates 211. Specifically, a pair of vertically extending guide rods 11 are provided on the frame 1. The pair of connecting plates 212 are respectively slidably arranged on the pair of guide rods 11. Linear bearings 2121 are installed on the connecting plates 212, and the linear bearings 2121 are slidably matched with the guide rods 11. In this embodiment, a vertically penetrating cavity 210 is provided on the moving seat 21. The cavity 210 is located below the insertion slot 141 and is directly opposite to the insertion slot 141. A positioning tongue 221 is movably arranged on the moving seat 21. The positioning tongue 221 is driven by a second driving device, and the second driving device is used to drive the positioning tongue 221 to move so that the positioning tongue 221 extends into or out of the cavity 210.

[0081] In the initial state, the moving seat 21 moves to the highest position. The sheet material 9 is vertically placed on the film material placing plate 14. The lower end of the sheet material 9 passes through the insertion slot 141 and enters the cavity 210. The positioning tongue 221 is used to position the lower end of the sheet material 9. A pair of limiting notches 132 are clamped on the edges of both sides of the sheet material 9 to perform horizontal positioning on the vertically placed sheet material 9. Before the sheet material 9 moves relative to the moving seat 21, the second driving device drives the positioning tongue 221 to move out of the cavity 210. Specifically, the second driving device is a first cylinder 23. The first cylinder 23 is horizontally arranged, and the positioning tongue 221 is arranged at the front end of the first cylinder 23. Limiting frames 13 are provided on both sides of the frame 1. The limiting frames 13 include rod bodies 133 fixed on the frame 1 and mounting seats 134 sleeved on the rod bodies 133. Adjusting handwheels are provided on the mounting seats 134. The adjusting handwheels penetrate through the mounting seats 134 and are sleeved on the side walls of the rod bodies 133. The adjusting handwheels are threadedly connected to the mounting seats 134. The front ends of the adjusting handwheels abut against the rod bodies 133. Positioning plates 131 are provided on the limiting frames 13. The positioning plates 131 are slidably arranged on the mounting seats 134 along the width direction of the film material placing plate 14. Long holes extending in the same direction as the sliding direction are provided on the positioning plates 131. Corresponding to the long holes, limiting screws are penetrated through the mounting seats 134. The limiting screws pass through the long holes, and a pair of nuts are provided on the limiting screws to lock the mounting seats 134 and the positioning plates 131. Limiting notches 132 with front sides and upper and lower openings are provided at the adjacent ends of the pair of positioning plates 131.

[0082] In this embodiment, the clamping device includes a chuck 222 and a clamping plate 211 respectively arranged on both sides of the cavity portion 210. The chuck 222 is driven by a driving device to move, so that the chuck 222 moves proximally or distally toward the clamping plate 211. During the process of the chuck 222 moving toward the proximal side of the clamping plate 211, it can clamp the sheet material 9 positioned above the positioning tongue 221. The clamping device clamps the lower end of the sheet material 9 between the chuck 222 and the clamping plate 211. When the chuck 222 and the positioning tongue 221 are simultaneously moved out of the outside of the cavity portion 210, the sheet material 9 can be moved downward out of the cavity portion 210.

[0083] Optionally, the chuck 222 is arranged at the end of the telescopic rod of a horizontally arranged cylinder (not shown). The cylinder body of the horizontally arranged cylinder is fixed on the moving seat 21. The moving direction of the chuck 222 is horizontal, and the chuck 222 is arranged above the positioning tongue 221. When the horizontally arranged cylinder is in the extended state, the chuck 222 can extend into the cavity portion 210 from one side of the cavity portion 210 to clamp the sheet material 9. When the horizontally arranged cylinder is in the retracted state, the chuck 222 moves out of the outside of the cavity portion 210.

[0084] In this embodiment, as Figure 8 , Figures 10 to 14 shown, the positioning tongue 221 and the chuck 222 are integrated on a movable block 22. Specifically, the movable block 22 is rotatably arranged on the moving seat 21, and the movable block 22 can be switched between a first posture, a second posture, and a third posture. The rotating shaft of the movable block 22 is arranged on one side of the cavity portion 210, and the positioning tongue 221 and the chuck 222 extend on the movable block 22.

[0085] As Figure 13 shown, when the movable block 22 is in the first posture, the positioning tongue 221 extends into the cavity portion 210 from one side of the cavity portion 210, and the positioning tongue 221 is used to support the bottom of the sheet material 9 penetrating into the cavity portion 210.

[0086] As Figure 14 shown, when the movable block 22 is in the second posture, the chuck 222 extends into the cavity portion 210 from one side of the cavity portion 210, and the sheet material 9 penetrating into the cavity portion 210 is pressed against the side wall of the cavity portion 210 away from the movable block 22 by the chuck 222.

[0087] As Figure 15 shown, when the movable block 22 is in the third posture, the positioning tongue 221 and the chuck 222 are rotated out of the outside of the cavity portion 210.

[0088] As Figure 8As shown in the figure, in this embodiment, one of the clamping plates 211 is the mounting plate 2111, and the movable block 22 is arranged on the mounting plate 2111. Correspondingly, an activity cavity 2110 for accommodating the rotation of the movable block 22 is provided on the mounting plate 2111, and a transmission guiding surface 223 is provided on the movable block 22; a first cylinder 23 in transmission connection with the movable block 22 is provided on the mounting plate 2111, and a roller 231 is provided at the upper end of the telescopic rod of the first cylinder 23; when the movable block 22 is in the first posture, the transmission guiding surface 223 extends out of the side of the mounting plate 2111 away from the cavity part 210, the first cylinder 23 is arranged below the transmission guiding surface 223, and the transmission guiding surface 223 is arranged opposite to the roller 231;

[0089] When the telescopic rod of the first cylinder 23 extends out, the roller 231 can push the transmission guiding surface 223 extending out of the mounting plate 2111 to rotate the movable block 22 to the second posture. Specifically, the number of the first cylinders 23 is 2, and they are arranged symmetrically along the width direction of the movable block 22. In this embodiment, the transmission guiding surface 223 is an inward concave arc surface tangent to the limiting hook part 224. When the movable block 22 is in the first posture and performs clamping, the roller 231 is pushed out by the first cylinder 23 to push the transmission guiding surface 223, so that the movable block 22 rotates to the second posture along the B direction. It should be noted that in this embodiment, during the process of the movable block 22 switching from the first posture to the second posture, the sheet material 9 will have a certain degree of downward trend, and the pressing wheel assembly 15 presses the flat film material 8 to generate a certain pulling force, which can overcome the downward movement of the sheet material 9 during this process. In this embodiment, a limiting hook part 224 is provided at the distal end of the transmission guiding surface 223. When the movable block 22 is in the second posture, the transmission guiding surface 223 rotates to the inside of the activity cavity 2110, the limiting hook part 224 extends out of the mounting plate 2111, the roller 231 abuts on the limiting hook part 224, and the limiting hook part 224 fits on the upper oblique side of the roller 231. It should be noted that: the "distal end" defined by the rotating parts of the present application is the end of each part away from the rotation axis core. In this embodiment, the inner side of the limiting hook part 224 is an arc surface adapted to the outer edge of the roller 231, and the limiting hook part 224 is used to limit the forward extension of the roller 231 and convert the forward pushing force of the roller 231 into the torsion force for the movable block 22 to rotate in the pressing direction.

[0090] In this embodiment, a positioning surface 2211 is provided on one side of the positioning tongue 221. When the movable block 22 is in the first posture, the positioning surface 2211 faces upward to support the bottom of the sheet material 9;

[0091] As Figure 13 、 15As shown, a driving surface 2212 is provided on the side of the positioning tongue 221 away from the positioning surface 2211; it also includes a top piece 12, the top piece 12 is fixed on the frame 1, the top piece 12 is vertically arranged, and the top piece 12 is arranged below the movable block 22. Corresponding to the top piece 12, a through groove 21110 is provided at the lower end of the mounting plate 2111, and the through groove 21110 vertically extends into the movable cavity 2110;

[0092] When the movable block 22 is in the second posture, the driving surface 2212 is located at the lower end of the movable block 22, and the upper end of the top member 12 is directly opposite to the driving surface 2212. At this time, after the second driving device drives the movable seat 21 to descend a preset distance, the top member 12 is used to push the driving surface 2212 to make the movable block 22 rotate to the third posture. Specifically, the driving surface 2212 is arc-shaped, one end of the driving surface 2212 extends to intersect with the far end of the positioning surface 2211, and the other end of the driving surface 2212 is connected to the transmission guide surface 223. The driving surface 2212 on the movable block 22 is resisted by the top member 12, so that the movable block 22 rotates from the second posture to the third posture. During this process, the positioning tongue 221 rotates toward the side of the cavity 210, and on the contrary, the chuck 222 rotates toward the side away from the cavity 210. In the third posture, the positioning tongue 221 is still in the movable cavity 2110 as a whole, and the chuck 222 rotates into the movable cavity 2110 as a whole. At the same time, the limit hook 224 rotates downward synchronously, and the roller 231 is pressed by the limit hook 224, so that the telescopic rod of the first cylinder 23 is retracted as a whole. It should be noted that when the roller 231 is pressed downward when the first cylinder 23 is in the extended state, the roller 231, i.e., the telescopic rod of the cylinder, can be retracted to a preset size. At this time, the limit hook 224 is used to convert the force generated by the movable block 22 rotating toward the third posture into a force to press the roller 231 downward.

[0093] like Figure 15 As shown, the top of the top piece 12 is rotatably provided with a roller 121, and when the roller 121 is in contact with the driving surface 2212, it is tangent to point A in the cross section, and point A is on the side of the straight line near the cavity 210 where the rotation center of the movable block 22 is located. Specifically, the top piece 12 is always set in the through groove 21110. The top piece 12 is a vertically set plate.

[0094] like Figure 8As shown, in this embodiment, torsion springs 24 are provided on both sides of the movable block 22, and the torsion springs 24 are coaxially arranged with the rotating shaft of the movable block 22. A pair of extension legs 241 are provided at both ends of the torsion spring 24, and the pair of extension legs 241 are respectively connected to the movable block 22 and the moving seat 21. Specifically, spring grooves adapted to the extension legs 241 are provided on the movable block 22 and the moving seat 21, and a limiting surface 21101 is provided in the movable cavity 2110; the torsion spring 24 is used to apply a torque to the movable block 22 so that the movable block 22 abuts against the limited surface 21101 in a natural state, and the movable block 22 is in a first posture at this time; when the movable block 22 is in the second posture and the third posture, the torsion spring 24 is in a compressed energy storage state. When the first cylinder 23 retracts until the roller 231 is disengaged from the transmission guide surface 223, the torsion spring 24 can reset the movable block 22 to the first posture. In addition, in this embodiment, the mounting plate 2111 is connected to the mounting block 21111, the mounting block 21111 is embedded in the mounting plate 2111, the movable block 22 is rotatably arranged on the mounting block 21111, and the movable cavity 2110 is arranged on the mounting block 21111. Correspondingly, the torsion spring 24 is also arranged on the mounting block 21111, and the processing difficulty of the mounting plate 2111 can be reduced by the split mounting block 21111.
