Description

Technical Field

[0001] This utility model relates to the technical field of paperboard production equipment, specifically a corrugated paperboard gluing and bonding device. Background Technology

[0002] Corrugated cardboard, as a commonly used packaging material, is widely used in various industries. In the production process of corrugated cardboard, gluing and lamination is a crucial step, directly affecting the quality and performance of the cardboard. A Chinese patent (publication number: CN220500130U) discloses an adjustable anti-warping mechanism and a cardboard hot-pressing lamination device, including a conveyor frame. This device laminates corrugated cardboard using a hot-press plate; however, this device still has certain shortcomings in use and needs further improvement.

[0003] In existing laminating devices, an electric conveyor belt is used to transport corrugated cardboard to the underside of a hot press plate for lamination. However, due to the lack of limiting the position of the corrugated cardboard, it cannot accurately reach the position directly under the hot press plate while being transported by the electric conveyor belt. This makes it easy for the position of the corrugated cardboard to cause poor lamination effect during hot pressing. The corrugated cardboard may also shift during hot pressing, affecting the lamination quality and causing inconsistent lamination of different parts of the cardboard. This requires operators to spend extra time and effort to adjust and correct, reducing production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a corrugated cardboard gluing and bonding device, which limits the corrugated cardboard by setting a horizontal plate and a threaded rod, thus solving the problem of corrugated cardboard displacement.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a corrugated cardboard gluing and bonding device, comprising a conveyor and a horizontal plate. The conveyor is equipped with a glue box and a frame, and the frame is equipped with a bonding part. A block is provided on the conveyor, and a first through hole and a second through hole are provided in the block. A threaded rod is fitted in the first through hole, and a horizontal bar is fitted in the second through hole. The horizontal plate is equipped with a threaded hole and a through hole. The threaded rod is threaded into the threaded hole, and the horizontal bar is fitted into the through hole.

[0007] Furthermore, a base block is installed at the end of the crossbar, and a rotating groove is opened in the base block, with the end of the threaded rod fitting into the rotating groove.

[0008] Furthermore, an L-shaped block is installed on the outer surface of the conveyor. A third through hole is opened on the L-shaped block, and a first rotating shaft is fitted inside the third through hole. A second rotating shaft is set at the bottom of the L-shaped block, and the end of the second rotating shaft is connected to the bottom of the block. Both the second rotating shaft and the first rotating shaft are fitted with bevel gears, and the two bevel gears mesh.

[0009] Furthermore, a stop is installed on the outer surface of the L-shaped block, and the stop is in contact with the outer surface of the block.

[0010] Furthermore, two fixing blocks are installed on the outer surface of the conveyor, and the glue box is installed on the two fixing blocks.

[0011] Furthermore, the bonding part has a cylinder and a hot plate, the cylinder is installed on the frame, and the hot plate is installed at the output end of the cylinder.

[0012] This utility model has the following beneficial effects:

[0013] This utility model effectively solves the problem of corrugated cardboard offset during lamination by setting a horizontal plate and threaded rod to limit the position of the corrugated cardboard. It can position and fix the corrugated cardboard when it is transported to the bottom of the hot press plate, ensuring that the corrugated cardboard is accurately placed under the hot press plate, thereby improving the lamination accuracy, reducing the lamination failure rate caused by position deviation, and improving the overall quality and consistency of the product.

[0014] This invention uses bevel gears and stops to move the horizontal plate. After the corrugated cardboard is laminated, the drive source is activated to rotate the first rotating shaft, which in turn drives the bevel gear on the first rotating shaft to rotate. At this time, the bevel gear on the meshing second rotating shaft rotates, causing the block to move away from the conveyor along with the second rotating shaft, thus avoiding obstructing the transmission of the corrugated cardboard and ensuring that the transmission of the corrugated cardboard is not affected. When it is necessary to limit the corrugated cardboard, the drive source is activated again to rotate the horizontal plate onto the conveyor, and the block is stopped by the stops to prevent excessive rotation angle, thereby increasing the practicality of this device.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a corrugated cardboard gluing and bonding device, including a conveyor 1 and a horizontal plate 7. Two fixing blocks 2 are installed on the outer surface of the conveyor 1. A glue tank 3 is installed on the two fixing blocks 2. During the conveying of the corrugated cardboard, glue is applied to the corrugated cardboard through the glue tank 3 to facilitate subsequent hot-pressing bonding. The conveyor 1 is equipped with the glue tank 3 and a frame 4. The frame 4 is equipped with a bonding section, which includes a cylinder 401 and a hot-press plate 402. The cylinder 401 is mounted on the frame 4, and the hot-press plate 402 is installed at the output end of the cylinder 401. After the conveyor 1 transports the corrugated cardboard to the bottom of the hot-press plate 402, the cylinder 401 is activated to push the hot-press plate 402 to the bottom for hot-pressing bonding of the corrugated cardboard. The conveyor 1 is equipped with a block 5, which has a first through hole. The first through hole 501 and the second through hole 502 are connected to a threaded rod 6, which is externally connected to a drive source. The second through hole 502 is connected to a crossbar 9, and a bottom block 8 is installed at the end of the crossbar 9. A rotating groove is opened in the bottom block 8, and the end of the threaded rod 6 is fitted into the rotating groove. The cross plate 7 has a threaded hole 701 and a through hole 702. The threaded rod 6 is threaded into the threaded hole 701, and the crossbar 9 is fitted into the through hole 702. When the corrugated cardboard is conveyed by the conveyor 1, the glue in the glue box 3 is applied to the corrugated cardboard and then transferred to the bottom of the hot press plate 402. At this time, the drive source is started to drive the threaded rod 6 to rotate. Since the cross plate 7 slides along the crossbar 9 through the through hole 702, the crossbar 9 limits the movement of the cross plate 7, so that the threaded rod 6 can drive the cross plate 7 to move to the outside of the hot press plate 402 when it rotates, thus limiting the movement of the corrugated cardboard.

[0023] An L-shaped block 10 is mounted on the outer surface of the conveyor 1. A third through hole is provided on the L-shaped block 10, and a first rotating shaft 11 fits inside the third through hole. The first rotating shaft 11 is externally connected to a drive source. A second rotating shaft 12 is located at the bottom of the L-shaped block 10. The end of the second rotating shaft 12 is connected to the bottom of the block 5, and the top of the second rotating shaft 12 is welded to the bottom of the block 5. The bottom end of the second rotating shaft 12 is rotatably fitted onto the base plate of the L-shaped block 10. Both the second rotating shaft 12 and the first rotating shaft 11 are fitted with bevel gears 13, which mesh. A stop 14 is installed on the outer surface of the 0, and the stop 14 contacts the outer surface of the block 5. After the corrugated cardboard is pasted, the drive source is started to drive the first rotating shaft 11 to rotate, which in turn drives the bevel gear 13 on the first rotating shaft 11 to rotate. At this time, the bevel gear 13 on the meshing second rotating shaft 12 is driven to rotate, so that the block 5 moves away from the conveyor 1 with the second rotating shaft 12 to avoid obstructing the transmission of the corrugated cardboard. When it is necessary to limit the corrugated cardboard, the drive source is started again to drive the horizontal plate 7 to rotate onto the conveyor 1, and the block 5 is held in place by the stop 14.
