Description

Technical Field

[0001] This utility model relates to the field of automatic welding equipment technology, and in particular to a hot melt welding device for hollow plate box assembly. Background Technology

[0002] The hollow plastic box is made from extruded sheet material. After extrusion, the cross-section of the sheet material has a hollow structure. When manufacturing folding plastic boxes, the assembly method of the box body can be snap-fit, screw fixing, hot melt welding, adhesive, or riveting and plugging. The choice can be made according to customer needs or performance requirements.

[0003] Our company primarily uses hot-melt welding for the assembly of the enclosures, which offers advantages such as high weld strength, tight and seamless welds, a neat and aesthetically pleasing appearance, and rapid assembly. The traditional method involves manually assembling the joints and welding them with a welding gun, which is less efficient.

[0004] Existing technology provides a hot-melt pressing and sealing device. This device, through components such as a mold table on a frame, a lower die, a mold table support mechanism, a side plate docking mechanism, a heat lamp and its driving mechanism, as well as a sealing knife lifting cylinder and an upper die, achieves heating and pressing sealing of the outer ends of two outer side plates of a plastic sheet after they are docked in a "human" shape on the lower die. The disadvantages of this device are: it contains multiple precision mechanical and electronic components, making the equipment overly complex and increasing maintenance costs; the heating efficiency of using heat lamps as heating units is low, while energy consumption is relatively high, increasing production costs; and the stability of pressing temperature and pressure control may be insufficient.

[0005] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0010] The hot air gun is connected to the crossbeam via a moving mechanism, and its heating end can be moved up, down, left, or right to enter or exit the hot melt position.

[0011] The front pressure roller assembly, located on the front side of the hot melt guide plate, is used to convey the box plate;

[0012] The rear pressure roller assembly is located behind the hot-melt position and is used to press the hot-melt box panels together.

[0013] Furthermore, a heat insulation sheet is provided on the right side of the hot melt inlet plate, which extends rearward to isolate the heating end from the lower box plate.

[0028] Please see Figures 1 to 4 The first embodiment of this utility model provides a hot-melt welding device for hollow slab box assembly, comprising:

[0029] The frame 1 has a working surface 11 and a crossbeam 12. The working surface 11 is provided with a box plate positioning strip 111, which extends along the transmission direction of the box plate 8 to complete the positioning of the box plate. The crossbeam 12 is erected above the working surface 11 to support other structures.

[0031] The hot air gun 6 is connected to the crossbeam 12 via the moving mechanism 5. By moving up, down, left, and right, its heating end can enter or exit the hot melt position.

[0032] A heat insulation sheet is installed on the right side of the hot melt inlet plate 4 and extends to the rear side to isolate the heating end from the lower box plate;

[0033] The front pressure roller group 2 is located on the front side of the hot melt guide plate 4 and is used to convey the box plate;

[0034] The rear pressure roller group 7 is located behind the hot melt position and is used to press the hot melt box plate together;

[0035] The front pressure roller group 2 and the rear pressure roller group 7 each include an upper connecting seat 22, an upper pressure roller 23, a lower connecting seat 24, and a lower pressure roller. The upper connecting seat 22 is connected to the crossbeam 12 through an elastic mechanism 21. The upper pressure roller 23 is rotatably mounted in the upper connecting seat 22 and is a driven roller. The lower connecting seat 24 is fixed below the working surface 11. The lower pressure roller is rotatably mounted in the lower connecting seat 24 and is a driven roller, driven by the pressure roller motor 25. The distance between the upper and lower pressure rollers is set according to the pressure required for conveying the box plate and pressing the hot-melt box plate.

[0036] Specifically, an introductory wheel is also provided on the front side of the upper pressure wheel 23 of the rear pressure wheel group 7. The introductory wheel is connected to the crossbeam 12 through the second connecting frame.
