Description

Technical Field

[0001] The invention belongs to the technical field of insulating paper gluing devices, and in particular relates to a composite quantitative gluing device for insulating paper. Background Art

[0002] Insulating paper production requires gluing. Existing gluing devices typically dip a gluing roller into a gluing tank, where it absorbs the glue and then applies it to the paper. However, the glue in the tank easily solidifies, and impurities easily enter the tank, making it difficult to filter out impurities between the tank and the gluing roller. Furthermore, the gluing roller is located at the top of the tank, making it difficult to fully utilize the glue at the bottom. The gluing thickness varies depending on the type and size of the insulating paper. Existing gluing devices offer a single gluing thickness, limiting their applicability. Summary of the Invention

[0003] The object of the present invention is to provide a composite quantitative gluing device for insulating paper with different gluing thicknesses.

[0005] Furthermore, a row of cylindrical rollers of the same height are connected to the receiving box, and sealing strips are provided on the front and rear sides of each cylindrical roller, and each sealing strip is fixedly connected to the receiving box.

[0006] Furthermore, a glue leakage port communicating with the receiving box is provided at the bottom of the glue box, and a push cover is installed on the glue leakage port; a sealing ring is installed at the top of the receiving box, and the receiving box and the glue box are detachably connected.

[0007] Furthermore, each cylindrical roller includes a sprocket located at both ends thereof, and a chain cooperating with the sprocket is connected between every two adjacent cylindrical rollers; mounting grooves are provided on the left and right walls of the accommodating box, and the sprocket and chain are both arranged in the mounting grooves, and a gap is provided between the sprocket and the sponge layer of each cylindrical roller.

[0008] Furthermore, the bottom of the glue box is a tilted wedge-shaped block structure, and a vertical filter plate is fixedly connected to the bottom of the glue box. The filter plate divides the glue box into a loading chamber and a glue leakage chamber, and the bottom surface of the loading chamber is higher than the bottom surface of the glue leakage chamber.

[0009] Furthermore, the glue leakage port is opened at the lowest point of the glue leakage chamber.

[0010] Furthermore, a stirring and heating integrated blade is provided in the feeding chamber; an air blowing port is provided above the compacting roller; an insulating paper limiter is provided between the glue box and the conveying flattening roller, and an insulating paper limiter is provided between the glue box and the compacting roller.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention arranges a containing box below the glue box and arranges a cylindrical roller inside the containing box, which can fully utilize the glue in the glue box. Compared with the glue trough, the glue box and the containing box of the present invention improve the utilization rate of the glue; the sponge layer on the outer layer of the cylindrical roller can be compressed to different thicknesses and release different amounts of glue. The lifting mechanism is arranged on the conveying flattening roller and the compacting roller, which can drive the conveying flattening roller and the compacting roller in front and behind the glue box to move up and down, and then drive the insulating paper between the conveying flattening roller and the compacting roller to move up and down, so that the insulating paper provides different pressures on the sponge layer, changes the amount of glue released by the sponge layer, and changes the glue thickness.

[0013] Arranging the cylindrical rollers in a row can increase the contact area between the sponge layer and the insulating paper, and increase the maximum gluing thickness; setting sealing strips on both sides of the cylindrical rollers can prevent glue leakage and make the gluing process of the insulating paper stable.

[0014] The detachable connection between the receiving box and the glue box facilitates the disassembly and assembly of the receiving box, and facilitates the replacement of the cylindrical roller when the glue on the cylindrical roller solidifies, thereby improving production efficiency.

[0015] A sprocket and a chain are arranged to connect the cylindrical rollers together, so that the cylindrical rollers rotate synchronously and the amount of glue applied remains uniform; a mounting groove is arranged in the wall of the accommodating box to prevent the sprocket and the chain from contacting the glue.

[0016] The bottom of the glue box is tilted, with one end higher and the other lower, allowing glue to flow from the loading chamber through the filter plate to the glue drain chamber, giving the glue box an automatic filtering effect. The glue drain port is located at the lowest point of the glue drain chamber, facilitating glue draining and fully utilizing the glue in the glue box. This reduces glue residue after the glue is drained.

[0017] The integrated stirring and heating blades can heat the glue in the glue box evenly to prevent solidification; the air blower can quickly solidify the glue on the insulating paper, improving production efficiency; the insulating paper limiter can prevent the insulating paper from shaking left and right during transportation, ensuring the stability of the production process.

The cylindrical roller 4-2 is parallel to the conveyor flattening roller 1. The cylindrical roller 4-2 includes an outer sponge layer 4-2-2, which prevents glue from flowing out when not subjected to external force. The greater the external force, the more glue flows out, thereby controlling the amount of glue applied. The lower portion of the sponge layer 4-2-2 is located below the container 4-1. The roller support frame 12 and the drying support frame 8 are both connected to a lifting mechanism. Each of the roller support frame 12 and the drying support frame 8 is connected to a set of vertical pneumatic push rods 11. The lower air inlet valves of the pneumatic push rods 11 are connected to the air pump via pipes. The rise distance of the pneumatic push rods 11 is controlled by controlling the air flow in and out of the air pump.

[0028] Each cylindrical roller 4-2 includes a cylindrical body, and the sponge layer 4-2-2 and the sprocket 4-2-1 are both arranged on the cylindrical body; a long screw 4-2-3 is installed at the lower part of the accommodating box 4-1, and each cylindrical body is coaxial with a long screw 4-2-3 and is sleeved on a long screw 4-2-3 and rotatably arranged; a semicircular notch equal to the diameter of the cylindrical body is opened on the inner wall of the installation groove, and the semicircular notch is stuck in the gap 4-2-4 between the sprocket 4-2-1 and the sponge layer 4-2-2, so that the inner wall of the installation groove separates the sprocket 4-2-1 from the sponge layer 4-2-2.

[0029] The bottom of the glue box 5 is an inclined wedge-shaped structure. A vertical filter plate 5-5 is fixedly attached to the bottom of the glue box 5. The filter plate 5-5 divides the glue box 5 into a loading chamber 5-2 and a glue leakage chamber 5-1. The filter plate 5-5 is evenly distributed with filter holes 6. The bottom surface of the loading chamber 5-2 is higher than the bottom surface of the glue leakage chamber 5-1.

An insulating paper limiter 3 is provided between the glue box 5 and the conveying flattening roller 1, and an insulating paper limiter 3 is provided between the glue box 5 and the compacting roller 10.

[0031] Example 2

[0032] This embodiment is a composite quantitative gluing device for insulating paper using the following method, including the following steps:
