If the glue supply is insufficient, it will affect the product quality. Content of the Utility Model

[0028] Example

[0029] like Figures 1 to 6 As shown, a fast-melting, easy-to-clean, large-capacity glue machine includes a glue cylinder 1. A heating and slitting device is provided at the feeding end of the glue cylinder 1. An extrusion device is provided above the heating and slitting device to extrude the hot-melt glue block 7 placed on the heating and slitting device. The extrusion device moves to extrude the hot-melt glue block 7 placed on the heating and slitting device, and the hot-melt glue strips are cut into a plurality of thin strips by the heating and slitting device and fall into the glue cylinder 1 for heating. A weight sensor 41 is installed on the bottom of the glue cylinder 1 for detecting the actual weight of the hot-melt glue liquid in the glue cylinder 1 in real time. With this structure, a heating and slitting device and an extrusion device are provided, that is, the extrusion device can extrude the hot melt adhesive block 7 placed on the heating and slitting device. Under the heat cutting action of the slitting opening 24 of the heating and slitting device, the large hot melt adhesive block 7 can be heat-cut into thin strips of semi-molten hot melt adhesive and fall into the glue cylinder 1 for heating, thereby greatly improving the melting efficiency; by installing a weight sensor 41 on the bottom of the glue cylinder 1, that is, the weight sensor 41 can detect the actual weight of the hot melt adhesive liquid in the glue cylinder 1 in real time, so that the glue in the cylinder can be replenished in time to ensure the quality of the product.

[0030] like Figure 1 and Figure 2 As shown, six legs 4 are symmetrically mounted on the bottom of the glue tank 1, each of which is equipped with a weight sensor 41. This structure, by properly arranging the number and distribution of weight sensors 41, allows for accurate, real-time detection of the actual weight of the hot melt adhesive liquid within the glue tank 1.

[0031] As shown in Figure 3, the glue cylinder 1 is provided with a glue cylinder opening 9 on one side. A horizontally arranged glue cylinder heating groove 5 is disposed within the interior of the glue cylinder 1, housing a second heating rod 51. This structure aligns the cleaning direction of the glue cylinder 1 with the glue cylinder opening, allowing for a low-lying opening, making it easier to clean carbides within the glue cylinder 1. This solves the problem of existing hot melt adhesive machines with high-ground openings and complex, intersecting heating grooves within the glue cylinder 1, making cleaning difficult.

[0032] like Figure 3 and Figure 4As shown in the figure, a gear pump 81 is provided on one outer side of the glue cylinder 1, and a hot melt adhesive outlet 6 connected to the output port of the gear pump 81 is provided on the other outer side of the glue cylinder 1; among them, the gear pump 81 is connected to the gear pump drive motor 82. Starting the gear pump drive motor 82 can drive the gear pump 81 to rotate, and then the hot melt adhesive liquid in the glue cylinder 1 can be transported to the hot melt adhesive outlet 6 and output to the next process through the hot melt adhesive outlet 6 for use.

[0033] As Figure 5 and Figure 6 shown in the figure, the heating and slitting device includes a heating base 21 connected to the glue cylinder 1. A heating and slitting plate 22 is provided in the middle of the heating base 21. An inward concave strip-shaped groove 23 is provided on the heating and slitting plate 22, and a slitting opening 24 penetrating through the upper and lower surfaces of the heating and slitting plate 22 is provided in each inward concave strip-shaped groove 23; a number of first heating rods 25 are horizontally distributed on the heating base 21. With this structure, that is, under the action of the heating and slitting plate 22, the slitting opening 24 and the extrusion assembly, the slitting opening 24 can hot-slit the large hot melt adhesive block 7 into thin strips to facilitate the heating and melting of the glue cylinder 1.

[0034] As Figure 5 shown in the figure, the extrusion device includes an extrusion plate 31 and an extrusion drive cylinder 3 connected to the extrusion plate 31; the extrusion drive cylinder 3 moves to drive the extrusion plate 31 to move in a direction close to or away from the heating and slitting device. With this structure, among them, the extrusion drive cylinder 3 is a cylinder. With this structure, when it is necessary to extrude the hot melt adhesive block 7 placed on the heating and slitting plate 22, control the movement of the extrusion drive cylinder 3. The extension rod of the extrusion drive cylinder 3 extends, driving the extrusion plate 31 connected to it to move downward to be able to extrude the hot melt adhesive block 7 placed on the heating and slitting plate 22 downward.

[0035] As Figure 5 and Figure 6 shown in the figure, a fixed cylinder 33 is provided on the top of the glue cylinder 1. The extrusion plate 31 is arranged in the fixed cylinder 33. The cylinder body of the extrusion drive cylinder 3 is fixedly connected to the top of the fixed cylinder 33. The tail of the extension rod of the extrusion drive cylinder 3 extends into the fixed cylinder 33 and is fixedly connected to the extrusion plate 31. With this structure, it is beneficial to drive the movement of the extrusion plate 31.

[0036] As Figure 1 shown in the figure, a feeding port 331 is provided on one side of the fixed cylinder 33; among them, the feeding port 331 is located above the heating and slitting assembly. With this structure, it is beneficial to the feeding of the hot melt adhesive block 7.

[0037] Working principle:

[0038] A large piece of hot melt adhesive block 7 is fed into the heating and slitting plate 22 from the feeding port 331. The thrust generated by the downward movement of the extrusion driving cylinder 3 is used to thermally cut the hot melt adhesive block 7 into thin strip-shaped semi-molten hot melt adhesive strips, which then fall into the glue cylinder 1 and continue to be heated and melted into a liquid. The real-time actual weight of the hot melt adhesive liquid in the glue cylinder 1 can be detected by these six weight sensors 41, and finally it is transported to the glue outlet 6 through the gear pump 81.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
