Description

Technical Field

[0001] The present application relates to the technical field of wet curtain gluing, and in particular to a wet curtain transfer and shaping device and a wet curtain gluing machine. Background Art

[0002] The corrugated paper on the surface of the wet curtain needs to be glued on one side. The lower surface of the glued corrugated paper is sticky. This corrugated paper will be attached to the previous corrugated paper. The multiple layers of corrugated paper are stacked and bonded together using glue to form the main structure of the wet curtain. The shape of the wet curtain is then regularized by cutting the edges. Because the lower surface of the corrugated paper is already sticky after gluing, the corrugated paper will shift during the transfer process, which will affect the regularity of the adhesion between the corrugated papers when stacked. A corrugated paper shaping mechanism is required to adjust the position of the corrugated paper to avoid excessive displacement of the corrugated paper during the stacking process. This will cause deviations in the stacking of the corrugated paper and reduce the yield rate of the wet curtain. An existing wet curtain automatic gluing machine with publication number CN114472097A uses a shaping mechanism to shape the wet curtain before and after gluing. However, the shaping mechanism can only meet the shaping requirements in one direction, and the shaping mechanism needs to be adjusted once during each transfer of corrugated paper. Depending on the size of the corrugated paper, multiple shaping mechanisms may need to be added, which results in high cost and low shaping efficiency. Summary of the Invention

[0065] See also Figures 1 to 3 , this embodiment provides a wet curtain transfer and shaping device, including a first transfer component 1 and a shaping component 2; the first transfer component 1 is arranged on a frame 5, including a first driving unit 11 and a plurality of transfer clamping arms 12, the plurality of transfer clamping arms 12 are distributed in an array along a first direction, and a first gap 13 is provided between two adjacent transfer clamping arms 12, the output end of the first driving unit 11 is connected to the plurality of transfer clamping arms 12, for driving the transfer clamping arms 12 to move along a second direction, and the transfer clamping arms 12 are used to transfer the corrugated paper 9; the shaping component 2 is arranged on the frame 5, including a first whole shaping component and a second shaping component, the first shaping component includes a plurality of first shaping brackets 21, the first shaping brackets 21 are distributed in an array along the first direction, and a first shaping bracket 21 is placed in a first gap 13, which is used to limit the movement position of the corrugated paper 9 in the second direction during the transfer process; the second shaping component is arranged adjacent to the first shaping component, and the second shaping component includes a plurality of second shaping brackets 22, the second shaping brackets 22 are distributed in an array along the second direction on the outside of the first transfer component 1, which is used to limit the movement position of the corrugated paper 9 in the first direction during the transfer process.

[0066] Figure 2 The x direction in the figure represents the first direction, and the y direction represents the second direction. The distribution of the first transfer component 1 and the first shaping bracket 21 and the second shaping bracket 22 can be combined. Figure 2 Understand.

[0067] Please refer to Figure 2 The transfer clamping arm 12 is connected to the first drive unit 11 through an adapter frame and a transmission assembly. The transmission assembly can be a chain drive, a belt drive, a gear rack drive, etc. A plurality of transfer clamping arms 12 are distributed in an array along the first direction on one side of the adapter frame, and the other side of the adapter frame is connected to the transmission assembly, and the transmission assembly is connected to the output end of the first drive unit 11. A slide rail is also provided on the adapter frame, and the adapter frame is movably connected to the frame 5 through the slide rail to support the plurality of transfer clamping arms 12. Through the rotation of the first drive unit 11, the plurality of transfer clamping arms 12 can simultaneously move forward or backward in the second direction to realize the action of transferring the textured paper 9.

[0068] In some embodiments, the adapter frame is detachably connected to the plurality of transfer clamp arms 12, and a plurality of spare adjustment holes are provided on the adapter frame. The transfer clamp arms 12 can be arranged in the adjustment holes of the adapter frame by means of bolt connections or snap connections. When the size of the first gap 13 between the transfer clamp arms 12 needs to be adjusted, this can be achieved by disassembling the transfer clamp arms 12. Corrugated paper 9 of different thicknesses has different bending radii. In order to prevent the corrugated paper 9 from excessively bending during the transfer process of the transfer clamp arms 12, resulting in irregular stacking, the size of the first gap 13 can be adjusted to control the density between the transfer clamp arms 12, thereby allowing the first transfer assembly 1 to adapt to corrugated paper 9 of various specifications and sizes.

[0069] Please refer to Figure 2 , multiple first shaping brackets 21 are distributed in an array along the first direction, and a first shaping bracket 21 is placed in a first gap 13. Optionally, the first shaping bracket 21 does not contact the transfer clamping arms 12 on both sides. The first shaping bracket 21 and the second shaping bracket 22 can be made of square tubes, or alloy profiles, or hollow round tubes, lean tubes, hard non-metallic pipes, etc. Since the first shaping bracket 21 and the second shaping bracket 22 are mainly used to block the movement of the corrugated paper 9, the force applied to the first shaping bracket 21 and the second shaping bracket 22 is relatively small, and they can be directly made of alloy profiles or lean tubes, or thicker steel wires or steel ropes, etc. As a preferred embodiment, the first shaping bracket 21 and the second shaping bracket 22 are made of alloy profiles, which are beautiful and low in cost, and have a certain load strength. The second shaping bracket 22 is used to limit the displacement of the corrugated paper 9 in the first direction. Optionally, the second shaping bracket 22 close to the input end of the corrugated paper 9 is tilted at a certain angle so that the second shaping bracket 22 has a preliminary guiding function, making the shaping of the corrugated paper 9 in the first direction smoother.

[0070] The first shaping component and the second shaping component are arranged adjacent to each other. In some embodiments, when the shape of the corrugated paper 9 is irregular, the first shaping component and the second shaping component can be tilted at a certain angle. By setting multiple mounting holes with tilted angles on the frame 5, the structural characteristics of the profile can be utilized to realize the disassembly and assembly of the first shaping component and the second shaping component to meet the production requirements of irregular corrugated paper 9.

[0071] Please refer to Figure 3Taking the corrugated paper 9 after gluing as an example, the specific working process of the transfer and shaping device is as follows: the corrugated paper 9 after gluing is output from the gluing component 8, and the first transfer component 1 is driven by the first driving unit 11 to move horizontally along the second direction to the output end of the gluing component 8. The corrugated paper 9 is driven by the gluing roller of the gluing component 8 to move into the transfer clamping arm 12. After the corrugated paper 9 is completely moved into the transfer clamping arm 12, the first driving unit 11 drives the transfer clamping arm 12 to move in the opposite direction of the second direction, driving the corrugated paper 9 on the transfer clamping arm 12 to move in the opposite direction of the second direction. When the transfer clamping arm 12 moves to the position where the first shaping bracket 21 is located, the corrugated paper 9 will stop at the side of the first shaping bracket 21. At this time, the transfer clamping arm 12 continues to move in the opposite direction of the second direction, causing the corrugated paper 9 to gradually detach from the transfer clamping arm 12 and finally fall on the upper surface of the previous corrugated paper 9 below, completing the shaping action. During this process, the second shaping bracket 22 is arranged along the second direction to limit the displacement of the corrugated paper 9 in the first direction. When the corrugated paper 9 moves from the gluing component 8 to the transfer clamp arm 12, the corrugated paper 9 can be shaped in real time in the first direction during the movement of the transfer clamp arm 12.

[0072] The above embodiment is different from the shaping idea adopted in the prior art. The corrugated paper 9 shaping in the prior art and other conventional shaping methods all set the shaping mechanism in a movable form, and use the movement of the shaping mechanism to achieve the regular shape of the cardboard. In the embodiment described in the present application, the shaping component 2 is fixed on the frame 5, and the moving function of the transfer mechanism is used to make the corrugated paper 9 close to the shaping component 2, thereby achieving the shaping effect of the corrugated paper 9, which reduces the cost of the shaping component 2 and does not require the drive unit required to drive the shaping component 2. The structure of the shaping component 2 is also simpler and does not require the customization of special-shaped workpieces. It can be achieved by using standard pipe materials. Moreover, the corrugated paper 9 can be shaped during the transfer process, saving the time required for first transferring and then shaping in the existing idea. Transferring and shaping are carried out simultaneously, which improves the shaping efficiency of the corrugated paper 9, thereby improving the efficiency of the entire wet curtain gluing process.

[0073] See also Figure 3In some embodiments, the transfer clamping arm 12 includes a first side clamping arm 121 and a second side clamping arm 122. The first side clamping arm 121 and the second side clamping arm 122 are arranged opposite each other, with a second gap 14 defined between them. The corrugated paper 9 is positioned within the second gap 14. The first side clamping arm 121 and the second side clamping arm 122 are made of cylindrical material to accommodate the larger size of the corrugated paper 9 in the cooling pad. The arrow in the figure indicates the direction of movement of the transfer clamping arm 12. The corrugated paper 9 is positioned within the second gap 14. In some embodiments, the first transfer assembly 1 is arranged before the corrugated paper 9 is glued, and the first side clamping arm 121 and the second side clamping arm 122 can move toward each other to clamp the corrugated paper 9 to prevent excessive deviation between the corrugated paper 9 and the predetermined gluing position, which would affect the gluing effect. In other embodiments, the first transfer assembly 1 is arranged after the corrugated paper 9 is glued, and the second gap 14 between the first side clamping arm 121 and the second side clamping arm 122 is fixed. After gluing, the corrugated paper 9 can automatically move into the second gap 14 under the drive of the output end of the gluing assembly 8. Since the bottom surface of the corrugated paper 9 now has glue, it can be fixed relative to the transfer clamping arm 12 in the second gap 14 without the need for clamping. At this time, the size of the second gap 14 should be greater than the thickness of the corrugated paper 9. As a preferred embodiment, the ends of the first side clamping arm 121 and the second side clamping arm 122 are V-shaped openings to facilitate the introduction of the corrugated paper 9 into the second gap 14. The first side clamping arm 121 and the second side clamping arm 122 are provided to firmly clamp the corrugated paper 9 and prevent the corrugated paper 9 from falling off the transfer clamping arm 12 due to external wind or other factors, thereby affecting the gluing efficiency of the wet curtain.

[0074] Please refer to Figure 3 In some embodiments, the height of the first side clamping arm 121 is lower than that of the second side clamping arm 122, and the first side clamping arm 121 is provided with an arc surface on the side close to the corrugated paper 9. When the first transfer assembly 1 is used to transfer the corrugated paper 9 after gluing, the height of the first side clamping arm 121 is lower than that of the second side clamping arm 122, and the bottom surface of the corrugated paper 9 contacts the upper surface of the first side clamping arm 121. Since there is glue on the bottom surface of the corrugated paper 9, the corrugated paper 9 is easily adhered to the upper surface of the first side clamping arm 121, affecting the subsequent shaping steps. Therefore, the first side clamping arm 121 is provided with an arc surface on the side close to the corrugated paper 9, so that the contact between the corrugated paper 9 and the upper surface of the first side clamping arm 121 is line contact, which greatly reduces the probability of the corrugated paper 9 adhering to the first side clamping arm 121, and also reduces the adhesion strength of the corrugated paper 9, facilitating the subsequent shaping steps. In some preferred embodiments, the first side clamping arm 121 can also be made into a wavy shape, so that the contact between the corrugated paper 9 and the upper surface of the first side clamping arm 121 is intermittent point contact, which greatly reduces the probability of the corrugated paper 9 sticking to the first side clamping arm 121, and also reduces the adhesion strength of the corrugated paper 9, which facilitates the subsequent shaping steps.

[0075] Please refer to Figure 2 In some embodiments, the wet curtain transfer and shaping device also includes a second drive unit 3, which is arranged on the frame 5. The output end of the second drive unit 3 is connected to the first transfer component 1, and the second drive unit 3 is used to drive the first transfer component 1 to move along the first direction to adjust the clamping position of the transfer clamp arm 12.

[0076] The second drive unit 3 can be a pneumatic cylinder, a motor, a hydraulic cylinder, or other drive device. The output end of the second drive unit 3 is connected to the first transfer assembly 1. Specifically, the output end of the second drive unit 3 can be connected to an adapter frame, which is provided with a slide rail arranged along the first direction to support the entire first transfer assembly 1 in the first direction. The provision of the second drive unit 3 enables the first transfer assembly 1 to be adjusted along the first direction, facilitating the second shaping bracket 22 to adjust the corrugated paper 9 of different sizes. The specific adjustment process is: when the size of the corrugated paper 9 used for the wet curtain produced is different in the first direction, before the corrugated paper 9 is glued, the second shaping component is fixed on one side of the first transfer component 1. This structural feature is utilized, and the position of the first transfer component 1 relative to the second shaping component is controlled by the second driving unit 3, so that the distance between one side of the corrugated paper 9 and the second shaping component is always maintained within one size. For example, it can be set so that the distance between the side edge of the corrugated paper 9 and the second shaping component is maintained within a width range of 2 cm, so that the second shaping bracket 22 in the second shaping component can adjust the offset of the corrugated paper 9 in the first direction.

[0077] The above embodiment adopts a shaping idea opposite to the prior art, and fixes the second shaping component on one side of the first transfer mechanism. By adding a second drive unit 3, the first transfer mechanism has the function of adjusting along the first direction to adapt to the adjustment requirements of corrugated paper 9 of different sizes. The simultaneous transfer and shaping method is used to replace the existing operation steps of first transferring and then shaping, which saves shaping time, improves the transfer and shaping efficiency of the corrugated paper 9, and further improves the gluing efficiency of the wet curtain.

[0078] Please refer to Figure 4, this embodiment also provides a wet curtain gluing machine, including a frame 5, a first tray 6, a second transfer assembly 4, a gluing assembly 8, a wet curtain transfer and shaping device and a second tray 7; the first tray 6 is arranged on the frame 5, for placing the corrugated paper 9 to be glued; the second transfer assembly 4 is arranged above the first tray 6, and includes: a negative pressure structure 41 with negative pressure, for sucking the corrugated paper 9 to be glued; a third driving unit 42 is connected to the negative pressure structure 41, for driving the negative pressure structure 41 to move along the second direction; the gluing assembly 8 is arranged on the opposite side of the second transfer assembly 4 along the second direction, for gluing the corrugated paper 9 to be glued sucked by the second transfer assembly 4; the wet curtain transfer and shaping device is the wet curtain transfer and shaping device mentioned above, which is arranged on the other side of the gluing assembly 8, for transferring and shaping the corrugated paper 9 after gluing; the second tray 7 is arranged below the wet curtain transfer and shaping device, for placing the corrugated paper 9 that has been glued.

[0079] The first tray 6 also includes a first tray transfer mechanism, specifically comprising a first tray drive unit, a transmission assembly, and a first tray slide. The first tray 6 is movably connected to the frame 5 via the first tray slide. The transmission assembly can be a chain drive or a pulley drive, and the first tray 6 is in transmission connection with the first tray drive unit via the transmission assembly. The first tray drive unit can be a drive device such as a motor. The first tray 6 can be gradually raised in height according to the number of corrugated paper sheets 9 to be glued, so that the corrugated paper sheets 9 to be glued and the gluing assembly 8 are always kept on the same horizontal plane, facilitating the second transfer mechanism to absorb the corrugated paper sheets 9 into the gluing assembly 8.

[0080] The second transfer assembly 4 includes a negative pressure structure 41 and a third drive unit 42. The third drive unit 42 is used to drive the negative pressure structure 41 to move in the second direction to transfer the corrugated paper 9 to be glued to the gluing assembly 8 for gluing. The third drive unit 42 can be a cylinder, and the negative pressure structure 41 can be a device with a negative pressure function, such as a vacuum suction cup, etc., which uses the pressure difference between the inside and the outside to adsorb the corrugated paper 9 on the negative pressure structure 41, and then send it into the gluing assembly 8. In some embodiments, the second transfer assembly 4 also includes a second transfer slide rail, and the negative pressure structure 41 is movably connected to the frame 5 through the second transfer slide rail. The negative pressure structure 41 only needs to adsorb the upper surface of the corrugated paper 9 to meet the use requirements. At the same time, the negative pressure structure 41 has multiple negative pressure adsorption holes. Therefore, it can be compatible with corrugated paper 9 of different sizes, and does not need to be equipped with a size adjustment device, thereby reducing the manufacturing cost of the second transfer assembly 4.

[0081] The gluing assembly 8 specifically includes an upper glue roller, a lower glue roller, a glue feed roller, a glue box, a glue drive unit, and a glue support. The upper, lower, and glue feed rollers are vertically arranged on the glue support from top to bottom and are in driving connection with the glue drive unit. The gap between the upper and lower glue rollers accommodates the corrugated paper 9. The glue feed roller is positioned within the glue box, with its upper portion exposed and in contact with the lower portion of the lower glue roller, delivering the glue liquid. Rotation ensures that the outer surface of the lower glue roller is in full contact with the lower surface of the corrugated paper 9, enabling gluing of the lower surface of the corrugated paper 9.

[0082] The second tray 7 further includes a second tray transfer mechanism, specifically comprising a second tray drive unit, a transmission assembly, and a second tray slide rail. The second tray 7 is movably connected to the frame 5 via the second tray slide rail. The transmission assembly may be a chain drive or a pulley drive, and the second tray 7 is in transmission connection with the second tray drive unit via the transmission assembly. The second tray drive unit may be a drive device such as a motor. The second tray 7 can be gradually lowered in height according to the amount of glued corrugated paper 9, so that the glued corrugated paper 9 and the first transfer assembly 1 are always kept on the same horizontal plane, facilitating the first transfer assembly 1 to transfer the corrugated paper 9.

[0083] In the above embodiment, the wet curtain transfer and shaping device is installed in the corrugated paper 9 transfer process after gluing, so that the corrugated paper 9 can be shaped and transferred simultaneously after gluing, saving the time of separate shaping of the corrugated paper 9 and improving the shaping efficiency. At the same time, the second transfer assembly 4 is added. The second transfer assembly 4 uses the principle of negative pressure adsorption to achieve the feeding action of the corrugated paper 9, which is adaptable to a wider range of specifications of the corrugated paper 9 and reduces production costs.

[0084] Please refer to Figure 5 and Figure 6In some embodiments, the negative pressure structure 41 includes a suction platform 412 and a first cavity 411. The suction platform 412 is disposed below the first cavity 411. The first cavity 411 has a negative pressure. The suction platform 412 has multiple suction holes. The negative pressure within the first cavity 411 draws the corrugated paper 9 to be glued through the suction holes. The suction platform 412 is disposed below the first cavity 411 to facilitate suction of the corrugated paper 9. The multiple suction holes on the suction platform 412 create a pressure difference between the inside and outside of the suction holes due to the negative pressure within the first cavity 411, enabling suction to the upper surface of the corrugated paper 9, thereby achieving suction of the corrugated paper 9. The shape and number of the suction holes are not limited, and can be easily configured and adjusted according to actual conditions. Each of the multiple adsorption holes has negative pressure. When facing corrugated paper 9 of different sizes, as long as the number of adsorption holes can cover most of the area of ​​the corrugated paper 9, the corrugated paper 9 can be adsorbed onto the adsorption platform 412. The smaller the corrugated paper 9, the smaller its mass, the less adsorption force required, and the fewer adsorption holes to cover. Therefore, the adsorption holes can adsorb corrugated paper 9 of different sizes. By providing the adsorption platform 412 and adsorption holes, the negative pressure structure 41 can adapt to corrugated paper 9 of various sizes, improving the universality of the second transfer mechanism.

[0085] Please refer to Figure 4 and Figure 5 In some embodiments, the second transfer assembly 4 further includes a negative pressure fan 43 for generating negative pressure; the negative pressure structure 41 further includes a receiving pipe 413, one end of which is in communication with the first chamber 411, and the other end of which is in communication with the negative pressure fan 43. The receiving pipe 413 can be a bellows or other metal pipe fittings. For example, in this embodiment, a pipe fitting made of a thin plate is combined with the bellows, so that the receiving pipe 413 has a certain degree of flexibility, which facilitates smoother movement of the negative pressure structure 41 in the second direction. At the same time, the elastic properties of the bellows are utilized to improve the sealing performance of the receiving pipe 413, and it will not become loose or ruptured due to frequent movement. Negative pressure can be generated by a negative pressure generator. In this embodiment, negative pressure can also be generated by the negative pressure fan 43. Compared with the negative pressure generator, the negative pressure fan 43 can provide a higher power negative pressure and is also lower in cost, which is more suitable for the use in this embodiment. The negative pressure fan 43 is in communication with the first chamber 411 through the receiving pipe 413 , and extracts gas from the first chamber 411 so that the first chamber 411 is always kept in a negative pressure state.

[0086] Please refer to Figure 5 and Figure 7In some embodiments, a first opening is provided on the side wall of the receiving pipe 413, and the second transfer assembly 4 further includes a first switch assembly 44. The first switch assembly 44 includes a flap 441, which is provided on the receiving pipe 413 to cover the first opening. The first switch assembly 44 is used to adjust the negative pressure in the negative pressure structure 41; the first switch assembly 44 can be placed in an open position or a closed position. When the first switch assembly 44 is placed in the open position, the flap 441 disengages from the first opening to allow air to enter, thereby reducing the negative pressure in the negative pressure structure 41. When the first switch assembly 44 is placed in the closed position, the flap 441 covers the first opening, isolating the air to maintain the negative pressure in the negative pressure structure 41.

[0087] Please refer to Figure 7 The first opening is provided on the side wall of the receiving pipe 413, and the flap 441 is used to cover the first opening. By controlling the opening and closing of the flap 441, the negative pressure in the receiving pipe 413 can be adjusted. The specific adjustment principle is as follows: when the first switch assembly 44 is in the open position, the flap 441 is disengaged from the first opening, and a large amount of air enters the receiving pipe from the outside. The negative pressure in the first chamber 411 decreases rapidly, and the adsorption force on the corrugated paper 9 also decreases synchronously, allowing the corrugated paper 9 to be brought in by the upper and lower rubber rollers and moved to the other end. When the first switch assembly 44 is in the closed position, the flap 441 covers the first opening, so that the receiving pipe 413 is kept in a sealed state again. The negative pressure value in the first chamber 411 then quickly returns to the set value and is maintained, which is used to adsorb the next piece of corrugated paper 9.

[0088] By setting the first switch component 44, the negative pressure in the negative pressure structure 41 can be adjusted to meet the usage requirements, avoiding the situation where the corrugated paper 9 is always adsorbed on the negative pressure structure 41 and cannot be fed into the gluing component 8, thereby improving the smoothness of the gluing action and the gluing efficiency of the wet curtain gluing machine.

[0089] Please refer to Figure 5 and Figure 7 The arrow in the figure indicates the direction of movement of this component. In some embodiments, the first switch assembly 44 includes a fourth drive unit 442, a swing arm 443, and a flip shaft 444. The swing arm 443 is disposed at the output end of the fourth drive unit 442. One end of the flip shaft 444 is sleeved with the swing arm 443, and the other end of the flip shaft 444 extends through the receiving pipe 413. The flap 441 is disposed at the portion of the flip shaft 444 disposed within the receiving pipe 413. The swing arm 443 is used to drive the flip shaft 444 and the flap 441 to rotate.

[0090] The fourth drive unit 442 can be hinged to the outside of the negative pressure structure 41, or can be set on the frame 5. In this embodiment, the fourth drive unit 442 is preferably set on the outside of the negative pressure structure 41. The swing arm 443 is hinged to the output end of the fourth drive unit 442, and one end of the flip shaft 444 is sleeved with the swing arm 443, and the other end of the flip shaft 444 passes through the receiving pipe 413 and is placed inside the receiving pipe 413. The flap 441 is fixedly connected to the flip shaft 444, and the output end of the fourth drive unit 442, the swing arm 443 and the flip shaft 444 form a connecting rod transmission assembly, which converts the linear motion of the fourth unit into the rotational motion of the flip shaft 444, thereby driving the flap 441 to rotate, realizing the opening and closing action of the flap 441 relative to the first opening, which can be specifically combined with Figure 7 For better understanding, the dotted line in the figure indicates the state where flap 441 is opened to a certain angle by the output of fourth drive unit 442, swing arm 443, and rotation of flip shaft 444. The provision of flip shaft 444 and swing arm 443 enables the opening and closing of flap 441, facilitating adjustment of the negative pressure within first chamber 411, thereby enabling automatic material receiving and unloading by second transfer assembly 4.

[0091] Please refer to Figure 5 In some embodiments, the negative pressure structure 41 further includes an air guide cavity 414 disposed between the receiving duct 413 and the first chamber 411. The cross-sectional area of ​​the connection between the air guide cavity 414 and the first chamber 411 is greater than the cross-sectional area of ​​the connection between the air guide cavity 414 and the receiving duct 413. The provision of the air guide cavity 414 allows the air in the first chamber 411 to circulate rapidly into the receiving duct 413, significantly improving the rate of regulating the negative pressure in the first chamber 411.

[0092] The above technical solution adopts a different idea from the existing technology. A plurality of transfer clamps 12 are arranged on the first transfer component 1. A first shaping bracket 21 is provided in the first gap 13 formed by two adjacent transfer clamps 12. The first shaping bracket 21 is arranged on the moving path of the first transfer component 1. The corrugated paper 9 is automatically abutted against the shaping component 2 by the first transfer component 1 during the process of transferring the corrugated paper 9. The first transfer component 1 continues to move, causing the corrugated paper 9 to fall off the transfer clamp 12. A second shaping bracket 22 is then added to limit the movement of the corrugated paper 9 in the other direction, thereby solving the shaping problem of the corrugated paper 9 in two directions after gluing. One shaping component 2 can adapt to corrugated paper 9 of multiple sizes, reducing the cost of the shaping mechanism. The corrugated paper 9 can be synchronously shaped during the transfer process, thereby improving the shaping efficiency.
