Description

Technical Field

[0001] This utility model relates to the field of double-sided adhesive application, and specifically to a double-sided adhesive application device. Background Technology

[0002] In the manufacturing process of corrugated cardboard boxes, gluing is a crucial step. This step ensures that the layers of corrugated cardboard are firmly bonded together, thereby improving the box's compression and bursting strength and preventing problems such as delamination and deformation during transportation and storage.

[0003] When applying glue to corrugated cardboard boxes, it is usually applied to one side. However, for sandwich-type corrugated cardboard boxes, the cardboard in the middle layer needs to be glued to both sides. In this case, applying glue to one side is not sufficient to meet the work requirements. In addition, the storage box containing glue during the glue application process does need to be cleaned regularly to prevent the glue from deteriorating. However, some glue application devices that directly immerse the glue roller in glue leave a large amount of glue residue at the bottom of the storage box, which is difficult to remove and also affects the cleaning of the storage box. Utility Model Content

[0004] Based on the above description, this utility model provides a double-sided adhesive applicator to solve the problem that some adhesive inside the glue storage box of existing adhesive applicators is difficult to pick up.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a double-sided adhesive applicator, including a workbench;

[0006] A power unit is installed at the bottom of the workbench;

[0007] The power assembly includes an electric telescopic rod, a top plate, and a limiting block, with a liquid storage tank installed on the top of the top plate;

[0008] A bracket is installed on the top of the workbench, and a first glue-applying roller is installed on the side wall of the bracket.

[0009] The top of the workbench is equipped with an installation plate, on which a liquid inlet tank, a liquid inlet pipe, and a second coating roller are installed.

[0010] The first and second coating rollers are positioned one above the other and distributed between the liquid storage tank and the liquid inlet pipe.

[0011] Furthermore, the workbench includes a support plate, a support column installed at the bottom of the support plate, and a through slot opened at one end of the support plate, with the top plate located in the inner cavity of the through slot.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, one side of the top plate is fixedly connected to the telescopic end of the electric telescopic rod, the limiting block is fixedly installed on the top of the top plate, and the top view of the limiting block is designed as a rectangle. The liquid storage tank is movably placed on the top plate, and the liquid storage tank is located at the center of the limiting block.

[0014] Furthermore, the two ends of the first coating roller are movably mounted on the bracket via a rotating shaft and bearings, and a rotating rod is fixedly connected to one end of the rotating shaft of the first coating roller.

[0015] Furthermore, a base block is fixedly installed at the bottom of the inner cavity of the liquid storage tank. The middle part of the base block is designed as a concave arc shape, and the two sides of the base block are set as inclined.

[0016] Furthermore, the liquid inlet pipe is fixedly installed at the bottom of the liquid inlet tank and is connected to the inner cavity of the liquid inlet tank. The opening of the liquid inlet pipe is located above the second coating roller.

[0017] Based on the above technical solution, the present invention can be further improved as follows.

[0018] Furthermore, a sealing part is installed on the side wall of the inlet pipe. The sealing part includes a fixing plate, a threaded rod, a sealing block, a sealing plate, and a limiting rod. The fixing plate is fixedly installed on the side wall of the inlet pipe, and one end of the threaded rod is connected to the sealing block and the sealing plate.

[0019] Furthermore, one end of the sealing block is fixedly connected to one side of the sealing plate, and the sealing block movably penetrates the side wall of the inlet pipe. One end of the threaded rod is threaded through the fixed plate and then movably connected to one end of the sealing block through a bearing.

[0020] Furthermore, one end of the limiting rod is fixedly connected to one end of the sealing block, and the end of the limiting rod away from the sealing block moves through the fixing plate.

[0021] Furthermore, the inlet pipe is divided into upper and lower parts, and a connecting plate is fixedly installed between the upper and lower parts of the inlet pipe. The two connecting plates are fixed together by bolts and nuts.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0023] 1. This utility model uses a power assembly on the workbench to push the liquid storage tank upward by using an electric telescopic rod in the power assembly, so that the glue inside the liquid storage tank can actively adhere to the first glue application roller, thus avoiding the problem of the glue at the bottom of the liquid storage tank not being picked up.

[0024] 2. By setting a bottom block in the inner cavity of the liquid storage tank and designing the top of the bottom block to be arc-shaped, the glue can be concentrated on the top of the bottom block. By concentrating the glue, the problem of glue residue in some parts of the inner cavity of the liquid storage tank is avoided, making it easier for the first glue application roller to pick up the glue.

[0040] Please see Figure 1 and Figure 2 A double-sided adhesive applicator, comprising a worktable 1;

[0041] A power unit 2 is installed at the bottom of the workbench 1;

[0042] The power assembly 2 includes an electric telescopic rod 201, a top plate 202 and a limiting block 203, and a liquid storage tank 3 is installed on the top of the top plate 202;

[0043] A support 4 is installed on the top of the workbench 1, and a first glue-applying roller 5 is installed on the side wall of the support 4.

[0044] A mounting plate 8 is installed on the top of the workbench 1, and an inlet tank 9, an inlet pipe 10, and a second coating roller 12 are installed on the mounting plate 8.

[0045] The first coating roller 5 and the second coating roller 12 are distributed one above the other between the liquid storage tank 3 and the liquid inlet pipe 10.

[0046] A power assembly 2 is installed on the workbench 1. The electric telescopic rod 201 in the power assembly 2 is used to lift the liquid storage tank 3, so that the glue inside the liquid storage tank 3 can be attached to the bottom of the first glue application roller 5 to complete the glue application work. In addition, this allows the first glue application roller 5 to also apply glue to the bottom of the inner cavity of the liquid storage tank 3.

[0047] Please see Figure 2 and Figure 3 The workbench 1 in this embodiment includes a support plate 101, a support column installed at the bottom of the support plate 101, and a through groove 102 opened at one end of the support plate 101. The top plate 202 is located in the inner cavity of the through groove 102.

[0048] The top plate 202 is located in the through groove 102 of the support plate 101, which facilitates the electric telescopic rod 201 to lift the top plate 202, allowing the top plate 202 to pass through the through groove 102, thereby driving the liquid storage tank 3 to move upward. The through groove 102 is opened so that one end extends through to the side wall of the support plate 101, which facilitates the removal of the liquid storage tank 3 from the top plate 202 and allows it to be moved away along the direction of the through groove 102.

[0049] Please see Figure 2 and Figure 3 In this embodiment, one side of the top plate 202 is fixedly connected to the telescopic end of the electric telescopic rod 201, the limiting block 203 is fixedly installed on the top of the top plate 202, and the top view of the limiting block 203 is designed as a rectangle. The liquid storage tank 3 is movably placed on the top plate 202, and the liquid storage tank 3 is located at the center of the limiting block 203.

[0050] A limiting block 203 is installed on the top plate 202 to limit the liquid storage tank 3, ensuring that the liquid storage tank 3 remains stable as the top plate 202 moves upward.

[0051] Please see Figure 2 In this embodiment, the two ends of the first glue-applying roller 5 are movably mounted on the bracket 4 via a rotating shaft and bearings, and a rotating rod 6 is fixedly connected to one end of the rotating shaft of the first glue-applying roller 5.

[0052] Rotating the rotating rod 6 can drive the first glue-applying roller 5 to rotate, allowing the first glue-applying roller 5 to pre-apply glue.

[0053] Please see Figure 3 In this embodiment, a bottom block 7 is fixedly installed at the bottom of the inner cavity of the liquid storage tank 3. The middle part of the bottom block 7 is designed as a concave arc shape, and the two sides of the bottom block 7 are set as inclined.

[0054] The middle part of the bottom block 7 is designed in an arc shape so that the glue can be concentrated in the middle of the bottom block 7, which makes it convenient for the first glue roller 5 to pick up the glue when the liquid storage tank 3 moves upward.

[0055] Please see Figure 1 In this embodiment, the liquid inlet pipe 10 is fixedly installed at the bottom of the liquid inlet tank 9, and the liquid inlet pipe 10 is connected to the inner cavity of the liquid inlet tank 9. The opening of the liquid inlet pipe 10 is located above the second coating roller 12.

[0056] An inlet pipe 10 is installed at the bottom of the inlet tank 9, and the glue inside the inlet tank 9 is guided to the second glue coating roller 12 by the inlet pipe 10.

[0057] Please see Figure 4 and Figure 5 In this embodiment, a sealing part 11 is installed on the side wall of the inlet pipe 10. The sealing part 11 includes a fixing plate 111, a threaded rod 112, a sealing block 113, a sealing plate 114, and a limiting rod 115. The fixing plate 111 is fixedly installed on the side wall of the inlet pipe 10, and one end of the threaded rod 112 is connected to the sealing block 113 and the sealing plate 114.

[0058] A sealing part 11 is provided to seal the inlet pipe 10, thereby enabling the inlet pipe 10 to be opened and closed.

[0059] Please see Figure 4 and Figure 5 In this embodiment, one end of the sealing block 113 is fixedly connected to one side of the sealing plate 114, and the sealing block 113 movably penetrates the side wall of the liquid inlet pipe 10. One end of the threaded rod 112 is threaded through the fixing plate 111 and then movably connected to one end of the sealing block 113 through a bearing.

[0060] Tighten the threaded rod 112 so that one end of the threaded rod 112 pushes the sealing block 113 to move. After the sealing block 113 enters the inner cavity of the liquid inlet pipe 10, it will seal the inner cavity of the liquid inlet pipe 10.

[0061] Please see Figure 4 and Figure 5 In this embodiment, one end of the limiting rod 115 is fixedly connected to one end of the sealing block 113, and the end of the limiting rod 115 away from the sealing block 113 moves through the fixing plate 111.

[0062] The limit rod 115 is designed to prevent the sealing block 113 from rotating arbitrarily when it moves.

[0063] Please see Figure 4 and Figure 5 In this embodiment, the liquid inlet pipe 10 is divided into upper and lower parts, and a connecting plate 13 is fixedly installed between the upper and lower parts of the liquid inlet pipe 10. The two connecting plates 13 are fixed together by bolts and nuts.

[0064] The upper and lower parts of the liquid inlet pipe 10 are connected by the connecting plate 13, which makes it easy to disassemble the upper and lower parts of the liquid inlet pipe 10 and to clean them, thus avoiding the solidification and blockage of the glue on the inner wall.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
