For those skilled in the art, the specific meaning of the above terms in this case can be understood according to the specific circumstances.

[0027] First, please refer to Figure 2 The double-layer paper holder involved in the present application is a practical packaging material used in the transportation and storage of high-security protection fields such as precision detection equipment, medical equipment, etc. Its features include the upper paper holder 100, which is provided with a concave structure of the equipment packaging cavity, and the equipment to be packaged is placed on the front face of the upper paper holder 100. The corresponding back face is a hollow structure, and in order to ensure excellent cushioning performance and structural strength, the lower paper holder 200 is embedded in the hollow back face.

[0028] At this time, glue needs to be applied to the outer edge 110 of the upper paper holder 100, and then the lower paper holder 200 is buckled and pressed. When the glue and pressing of the double-layer paper holder as described above are performed, the stability and work efficiency need to be considered.

[0029] Please refer to Figure 1 For this purpose, the double-layer paper holder glue spraying production system of the present application includes a glue spraying area P3 for spraying glue on the back face of the upper paper holder 100, that is, spraying glue on the outer edge 110. The glue spraying area P3 is provided with an automatic glue spraying device 1, and a feeding area P2 for supplying the upper paper holder 100 and the lower paper holder 200 is provided on the working area side of the glue spraying area P3. At the same time, a glue supply area P1 is provided for supplying glue to the glue spraying area P3, and the glue supply area P1 is provided with a glue feeding pump 2 and a glue tank 21. By means of automatic pumping, the consistency of the amount of glue sprayed each time can be ensured.

[0030] At this time, the automatic glue spraying device 1 can make the glue evenly distributed, further improving the stability of the double-layer paper holder 300. In the subsequent drawings and embodiments, the reference number of the double-layer paper holder 300 will be used, and the effect after the lower paper holder 200 is buckled to the upper paper holder 100 will be shown. The same figure of the lower paper holder 200.

[0031] On the other hand, a storage area P4 is set perpendicular to the glued area P3 to temporarily store the upper paper tray 100 and the lower paper tray 200 that are attached to the glued area P3. The storage area P4 holds the semi-finished product that has not been pressed after the double-layer paper tray 300 has been snapped together. The snapping operation can be performed by snapping the lower paper tray 20 onto the glued area P3 directly after the glue has been applied.

[0032] Adjacent to the storage area P4, a hot pressing area P5 is arranged to press the double-layer paper trays 300 in the storage area P4 together, and a unloading area P6 is arranged to unload and store the pressed double-layer paper trays 300. A hot press 3 is provided in the hot pressing area P5. The hot press 3 can adopt a mold pressing method, which is a common technical means in the industry and is not specifically limited thereto.

[0033] This application mainly utilizes the vertically arranged storage area P4, hot pressing area P5, and unloading area P6 to optimize the material flow path, making production smoother, reducing the waiting time between gluing and hot pressing, and improving production continuity and efficiency.

[0034] The automatic glue application equipment 1 is described in detail below. Please refer to the following description. Figure 3 and Figure 4 The automatic glue application equipment 1 is a robotic arm device. The use of robotic arms in automated equipment is primarily due to cost considerations. Therefore, a simple linear axial robotic arm is preferred for achieving precise glue application across the entire plane.

[0035] Therefore, the automatic glue application equipment 1 includes a glue application table 10 as the glue application work surface, and X-axis arms 11 are arranged on both sides of the glue application table 10. The X-axis arms 11 can provide a track for Y-axis arms 12 to move back and forth, that is, the Y-axis arms 12 are arranged at the upper end of the X-axis arms 11.

[0036] Furthermore, the Z-axis arm 13 moves left and right on the Y-axis arm 12, and the glue applicator 14 moves up and down on the Z-axis arm 13. At this time, the driving devices for the Y-axis arm 12, Z-axis arm 13, and glue applicator 14 are motors. A stable robotic arm structure can be achieved through simple means.

[0037] Furthermore, the glue applicator 14 is equipped with a glue gun 141, and the glue pump 2 is connected to the glue gun 141. The glue applicator 14 is also equipped with a pressure adjusting device 142 for adjusting the amount of glue applied.

[0038] As the limiting device to the position of the upper paper tray 100, a limiting frame 15 is arranged on the upper end of the gluing table 10. The number of the limiting frame 15 can be adjusted according to the rhythm of the production operation, and four limiting frames 15 are applied in the embodiment. In order to facilitate the loading and unloading of the paper tray, the inner frame of the limiting frame 15 is arranged to be larger than the outer frame of the upper paper tray 100, and the outer frame refers to the outer frame of the outer edge 110 at this time.

[0039] At this time, there is a hidden danger that the upper paper tray 100 is offset during gluing. In this regard, preferably, a non-slip pad 16 is laid at the bottom of the limiting frame 15, and the non-slip pad 16 is provided with a plurality of non-slip holes 161. First, the non-slip pad 16 can be made of plastic or a plate-shaped resin plate with a non-slip effect. And the arrangement of the non-slip hole 161 can also play a limiting role to the upper paper tray 100, and can also accommodate the overflowed glue to prevent the glue from spreading on the operation table.

[0040] As described above, the application protects a double-layer paper tray glue spraying production system, and all technical solutions the same as or similar to the application should be shown to fall within the protection scope of the application.
