[0031] The utility model provides a glue-spraying device, which is used for fully mixing multi-component glue.

[0032] See also Figure 1-Figure 5 In an embodiment of the utility model, the glue-spraying device comprises a material box 1 and a rubber mixing tube 2; the material box 1 is provided with a first inner cavity, in which a partition plate 102 is provided, the partition plate 102 is used to divide the inner cavity into two accommodating chambers 101, and the outer wall of the material box 1 is provided with a first feed port 103 and a first discharge port 104 connected to the accommodating chamber 101; one end of the rubber mixing tube 2 is connected to the first discharge port 104, and a plurality of stop plates 201 are provided on the tube wall of the rubber mixing tube 2, and the plurality of stop plates 201 are connected in sequence along the axial direction of the rubber mixing tube 2, and the surfaces of two adjacent stop plates 201 have an angle.

[0033] In the technical solution of the present invention, the material box 1 is cylindrical or square cylindrical, and its shape can also be changed according to specific needs. The first inner cavity is divided into two accommodating chambers 101 by a partition plate 102. The two accommodating chambers 101 are used to store glue of different components. Each accommodating chamber 101 has a first feed port 103 and a first discharge port 104. That is, in this embodiment, the number of accommodating chambers 101, the first feed port 103 and the first discharge port 104 are two. Therefore, the present invention can mix glue of two different components. The number of partition plates 102 can also be changed according to the number of glue components. The mixing tube 2 is connected to the material box 1. During use, the glue inside the material box 1 enters the mixing tube. The inside of the rubber tube 2 uses multiple stopper plates 201 connected in sequence. The stopper plates 201 are elliptical plates. There is a gap between the side wall of the stopper plate 201 and the inner wall of the rubber mixing tube 2. In this way, it can be ensured that the glue can flow inside the rubber mixing tube 2. During the gluing process, the glue enters the gap. During the flow, it contacts and collides with the stopper plate 201. The glue is dispersed and polymerized. The mixed glue flows out from the upper end of the rubber mixing tube 2. When facing multi-component glue, no additional mixing process is required. Among them, multiple stopper plates 201 are fixed to the rubber mixing tube 1. When the glue enters the rubber mixing tube 1, the pressure generated by the glue is prevented to push the stopper plate 201 out of the rubber mixing tube 1.

[0034] See also Figure 1 and Figure 2 In one embodiment of the present invention, the material box 1 has an upper end and a lower end in the height direction, the first feed port 103 is located at the lower end of the material box 1 , and the first discharge port 104 is located at the upper end of the material box 1 .

[0035] In the technical solution of the utility model, the glue enters the accommodating chamber 101 from the first feed port 103 and then flows out from the first discharge port 104. A push plate may also be provided inside the accommodating chamber 101, and its cross section is the same as that of the accommodating chamber 101. During use, the push plate can be pushed to provide pressure to the glue.

[0036] See also Figure 1 and Figure 3 In one embodiment of the utility model, the rubber mixing tube 2 and the material box 1 are movably connected.

[0037] In the technical solution of the utility model, a movable connection is adopted, and the mixing hose 2 or the material box 1 can be quickly replaced. Before use, a plurality of material boxes 1 can be prepared and filled with glue. When the glue is used up, a new material box 1 can be directly replaced to continue gluing. If the mixing hose 2 is damaged, the mixing hose 2 can be directly replaced.

[0038] See also Figure 1-Figure 3 In one embodiment of the utility model, the rubber mixing tube 2 and the material box 1 are movably connected via a connecting piece 6 .

[0039] In the technical solution of the utility model, the connector 6 is movably connected, so that the material box 1 or the mixing hose 2 can be quickly replaced.

[0040] See also Figure 2 In one embodiment of the utility model, the connecting member 6 is a hollow tubular structure with openings at both ends. One end of the connecting member 6 is connected to the first discharge port 104. The outer wall of the connecting member 6 is provided with an external thread. The lower end of the mixing tube 2 is provided with an internal thread matching the external thread. The end of the connecting member 6 opposite to the material box 1 is connected to the mixing tube 2 through an external thread and an internal thread.

[0041] In the technical solution of the utility model, if it is necessary to replace the material box 1 or the mixing tube 2 during use, the material box 1 or the mixing tube 2 can be replaced by rotating the material box 1 or the mixing tube 2 to separate them. It is convenient to replace the material box 1 or the mixing tube 2.

[0042] See also Figure 1 Furthermore, in one embodiment of the utility model, the gluing device also includes a temporary storage box 3, which is provided with a second inner cavity, and the outer wall of the temporary storage box 3 is provided with a second feed port 301 and a second discharge port 302 connected to the second inner cavity, and the end of the mixing tube 2 away from the material box 1 is connected to the second feed port 301, and the second discharge port 302 is provided with a glue nozzle structure.

[0043] In the technical solution of the utility model, during use, a temporary storage box 3 is provided. Since a second inner cavity is provided inside the temporary storage box 3, after the glue enters the second inner cavity, the glue mixing pipe 2 below it continues to discharge glue, which generates pressure on the glue that has entered the second inner cavity, causing the glue that has entered the second inner cavity to move irregularly, which can achieve mixing of the glue to a certain extent, further improving the mixing effect of the glue.

[0044] See also Figure 1 and Figure 3 In one embodiment of the utility model, the glue nozzle structure includes a glue outlet tube 401 and a glue outlet nozzle 402. One end of the glue outlet tube 401 is connected to the second discharge port 302, and one end of the glue outlet nozzle 402 is connected to the end of the glue outlet tube 401 opposite to the second discharge port 302. The glue outlet is provided at the end of the glue outlet nozzle 402 opposite to the glue outlet tube 401.

[0045] In the technical solution of the present utility model, the number of second discharge ports 302 is three, and each second discharge port 302 is provided with a glue discharge pipe 401. The number of second discharge ports 302 and glue discharge pipes 401 can be changed according to actual needs. When in use, the glue enters the glue discharge pipe 401 from the temporary storage box 3, and then flows into the glue discharge nozzle 402 through the glue discharge pipe 401. The glue discharge nozzle 402 has glue discharge ports of different shapes and sizes. The glue discharge pipe 401 with glue discharge ports of different sizes and shapes can be selected according to specific needs.

[0046] See also Figure 1 In one embodiment of the utility model, an end of the discharge pipe 401 connected to the second discharge port 302 is provided with an external thread, and an internal thread is provided in the second discharge port 302, and the discharge pipe 401 and the temporary storage box 3 are threadedly connected.

[0047] In the technical solution of the utility model, the rubber outlet pipe 401 and the temporary storage box 3 are connected by a threaded connection that is easy to disassemble. During use, if the rubber outlet pipe 401 is blocked or damaged, the rubber outlet pipe 401 can be directly unscrewed and replaced.

[0048] See also Figure 1 In one embodiment of the utility model, the end of the glue nozzle 402 connected to the glue nozzle 402 is provided with an external thread, and the end of the glue pipe 401 opposite to the temporary storage box 3 is provided with an internal thread, and the glue nozzle 402 is threadedly connected to the glue pipe 401.

[0049] In the technical solution of the utility model, the glue nozzle 402 and the glue pipe 401 are connected by a threaded connection that is easy to disassemble. During use, if the glue nozzle 402 is blocked, the glue nozzle 402 can be directly unscrewed and replaced.

[0050] See also Figure 6 The utility model also provides a glue gun 5, which includes a piston rod 501 and a glue device. The specific structure of the glue device refers to the above embodiment. Since the glue gun 5 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the piston rod 501 extends into the interior of the accommodating cavity 101.

[0051] In the technical solution of the utility model, the material box 11 is installed on the glue gun 5, the piston rod 501 of the glue gun 5 is inserted into the accommodating chamber 101, and the material box 11, the mixing tube 22, the temporary storage box 33 and the glue outlet component 4 are assembled, and it can be used. During the movement of the multi-component glue in the glue device, they will contact and collide with the stopper 201, disperse and reorganize, so as to achieve mixing. The glue enters the temporary storage box 3. Since a second inner cavity is arranged inside the temporary storage box 3, after the glue enters the second inner cavity, the mixing tube 2 below continuously discharges glue, which generates pressure on the glue that has entered the second inner cavity, causing the glue that has entered the second inner cavity to move irregularly, which can achieve mixing of the glue to a certain extent, further improving the mixing effect of the glue, and then the glue enters the glue outlet component 4 and flows out from the glue outlet nozzle 402 of the glue outlet component 4.
