[0001] This utility model relates to the field of adhesive supply technology, specifically to an adhesive supply device. Background Technology

[0002] In the prior art, glue supply devices typically use a single glue supply tank to supply the coating device with the coating glue, and the glue supply tank can only hold one filter element to filter the glue, resulting in a small volume of glue supply tank. The above-mentioned glue supply devices have the following problems: on the one hand, the filtration rate is low, the glue supply rate is low, which affects the coating efficiency of the glue; the filter element needs to be replaced frequently; on the other hand, once the glue supply device malfunctions or the filter element needs to be replaced, the operation of the glue supply device needs to be stopped, which greatly reduces the glue supply efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the defects in the existing technology and provide a glue supply device that improves the glue supply rate and increases the production efficiency of glue supply and coating.

[0004] To achieve the above-mentioned technical effects, the technical solution of this utility model is as follows: a glue supply device, comprising a glue storage tank, a screw pump and a coating device arranged in sequence, wherein a glue supply flow path is provided between the glue storage tank and the coating device, and the glue supply flow path is provided with three or more glue supply flow paths arranged in parallel.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figure 1-4 As shown in the embodiment, an adhesive supply device includes an adhesive storage tank 1, a screw pump 2 and a coating device 3 arranged in sequence. An adhesive supply path is also provided between the adhesive storage tank 1 and the coating device 3. The adhesive supply path is provided with three or more adhesive supply paths arranged in parallel.

[0029] The screw pump 2 includes a first screw pump 21 disposed between the glue storage tank 1 and the glue supply path, and a second screw pump 22 disposed between the glue supply path and the coating device 3;

[0030] A first valve 4 and a glue supply tank 5 are provided on any glue supply flow path, with the first valve 4 located at the glue inlet end of the glue supply tank 5;

[0031] The glue supply tank 5 includes a lid 51, a body 52 and a bottom 53 arranged sequentially from top to bottom. The body 52 includes a side wall 521 and a bottom wall 522. The side wall 521 is provided with a heating component 56, and the bottom wall 522 is provided with a plurality of receiving through holes 523. The receiving through holes 523 contain filter elements 57.

[0032] like Figure 1 As shown, each glue supply path is equipped with a first valve 4 and a glue supply tank 5. The opening and closing of the first valve 4 controls the opening and closing of the glue supply path it is located in, and also facilitates the maintenance of the glue supply tank 5 and the glue supply path. By setting multiple glue supply paths in parallel, on the one hand, more glue can be filtered and processed at the same time, increasing the supply of coating glue; on the other hand, if any glue supply path is closed, such as if the glue supply path malfunctions, the glue supply tank 5 needs maintenance, or the filter element 57 in the glue supply tank 5 needs to be replaced, there are still other glue supply paths to transmit glue, which does not affect the supply of coating glue.

[0033] At least three glue supply paths are provided to improve glue supply efficiency; furthermore, one of the glue supply paths serves as a backup path so that when the glue supply tank 5 is replacing the filter element 57 or is being repaired, there are two glue supply paths simultaneously supplying glue to the coating device 3.

[0034] The heating component 56 is designed to increase the fluidity and uniformity of the adhesive. Each glue supply tank 5 is equipped with multiple filter elements 57 to filter the adhesive, thereby improving the coating quality, filtration rate, and supply speed of the adhesive, thus increasing the production efficiency of adhesive coating.

[0035] Furthermore, the heating component 56 can be an electric heating tube, which can heat the adhesive liquid in the glue supply tank 5 after being powered on.

[0036] In this embodiment, the side wall 521 of the barrel 52 has a double-layer structure, and a space for accommodating the heating component 56 is provided between the two layers.

[0037] Furthermore, in this embodiment, the glue supply tank 5 is equipped with five filter elements 57 to filter the glue liquid.

[0038] like Figure 3 As shown, in another preferred embodiment, the bottom wall 522 divides the glue supply tank 5 into two parts: an upper cavity 541 and a lower cavity 542; the glue liquid is filtered from the upper cavity 541 through the filter element 57 and then enters the lower cavity 542.

[0039] The upper cavity 541 contains unfiltered adhesive liquid, while the lower cavity 542 contains filtered adhesive liquid.

[0040] The adhesive liquid in the upper cavity 541 is filtered by multiple filter elements 57 installed on the bottom wall 522 and then collected in the lower cavity 542, and supplied to the coating device 3 for adhesive coating.

[0041] A second valve 6 is also provided on the glue supply path, and the second valve 6 is located at the glue outlet end of the glue supply tank 5.

[0042] The second valve 6 is used to control whether glue is dispensed from the glue supply tank 5; the second valve 6 works in conjunction with the lower cavity 542 to allow the filtered glue to stand in the lower cavity 542 at the bottom 53 of the tank for a period of time, thereby further removing air bubbles from the glue and improving the glue coating quality.

[0043] like Figure 1-2 As shown, in another preferred embodiment, the side wall 521 is provided with an inlet 524, and the glue supply tank 5 is connected to the first valve 4 through the inlet 524; the bottom 53 of the tank is provided with an outlet 531, and the glue supply tank 5 is connected to the second valve 6 through the outlet 531.

[0044] The adhesive enters the upper cavity 541 of the glue supply tank 5 through the glue inlet 524 and flows out of the glue supply tank 5 through the glue outlet 531.

[0045] like Figure 2 As shown, in another preferred embodiment, the bottom 53 of the bucket is provided with a drain outlet 532.

[0046] The drain outlet 532 is designed to periodically remove long-term sediment from the lower cavity 542.

[0047] like Figure 4-6 As shown, in another preferred embodiment, the filter element 57 includes an upper cover plate 571, a filter element body 572 and a lower cover plate 573, and a limiting protrusion 574 is provided extending radially along the outer circle of the upper cover plate 571; the outer diameter of the limiting protrusion 574 is larger than the diameter of the accommodating through hole 523.

[0048] The outer diameter of the filter element 57 is equal to the diameter of the receiving through hole 523, so that the receiving through hole 523 can accommodate the filter element 57 and radially limit the filter element 57 in the radial direction; the outer diameter of the limiting protrusion 574 is greater than the diameter of the receiving through hole 523, so that the receiving through hole 523 can limit the filter element 57 in the vertical direction.

[0049] Furthermore, the filter element 57 is fixed in the receiving through hole 523, and a sealing ring is provided between the filter element 57 and the receiving through hole 523 to prevent the adhesive in the upper cavity 541 from leaking into the lower cavity 542 through the receiving through hole 523.

[0050] like Figure 3-5 As shown, in another preferred embodiment, a pressure plate 58 is also provided inside the glue supply tank 5. The pressure plate 58 is provided with a through hole 581 with the same diameter as the receiving through hole 523. The through hole 581 and the receiving through hole 523 are aligned and pressed onto the filter element 57.

[0051] The pressure plate 58 fixes the filter element 57 in the vertical direction, ensuring the stability of the filter element 57. At the same time, the pressure plate 58 increases the weight of the filter element 57, ensuring the tightness of the seal between the filter element 57 and the receiving through hole 523. The perforation 581 on the pressure plate 58 allows the adhesive liquid in the upper cavity 541 to pass through the perforation 581 and the filter element 57 in sequence into the lower cavity 542.

[0052] like Figure 3-5 As shown, in another preferred embodiment, an elastic abutment 59 that cooperates with the pressure plate 58 is also provided. One end of the elastic abutment 59 is pressed against the upper surface of the side wall 521 of the barrel 52, and the other end abuts against the pressure plate 58.

[0053] The elastic abutment 59 further secures the filter element 57, preventing it from shifting and affecting the filtration effect when the adhesive fluid moves within the glue supply tank 5.

[0054] like Figure 2-4 As shown, in another preferred embodiment, the bucket lid 51 is connected to a pressure gauge 55.

[0055] like Figure 2-4 As shown, in another preferred embodiment, the bucket lid 51 is provided with a vent 511.

[0056] The pressure inside the glue supply tank 5 is monitored in real time by pressure gauge 55; the vent 511 is designed to open and release gas from the glue supply tank 5 when the pressure is too high, preventing excessive pressure and potential explosion. Furthermore, a valve is installed at the vent 511 to control its opening and closing.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
