Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production equipment, in particular to a hot glue gun assembly. Background Art

[0002] The hot glue gun assembly is one of the core accessories of the strip carton packing machine in the tobacco production industry. The glue is heated in an external glue machine until it becomes liquid, and then it is pressurized and pressed into the glue path channel of the hot glue gun assembly through a pipeline. When glue is needed, it is ejected through the spray nozzle after the electrical instruction to open the spray nozzle, thus completing the gluing action.

[0003] In the existing hot glue gun assemblies, as Figure 1 shown, multiple modules are detachably connected and jointly form a glue path channel. Higher installation and positioning accuracy and reliable sealing are required between the modules. Slight errors or poor sealing will lead to failures. At the same time, maintenance is time-consuming and laborious because the multiple modules are arranged and installed in sequence. If a certain module is damaged, all the modules need to be removed together for maintenance. This brings great trouble to the on-site installation and maintenance personnel, and the maintenance efficiency is extremely low. At the same time, the hot glue gun is a precision and easily damaged accessory in production practice. Damage or abnormality will cause the whole equipment to stop. In addition, the existing glue gun has a complex structure, and maintenance is time-consuming and laborious, with poor economy. Summary of the Utility Model

[0028] As Figures 2 to 4 shown, a hot glue gun assembly includes a housing body 1. The housing body 1 includes a plurality of detachable plate members, and one side of the housing body 1 is open. Specifically, it includes a top plate 11, a back plate 12, a bottom plate 13 and two side plates. The top plate 11 and the back plate 12 are formed by bending, and are connected to the bottom plate 13 through a bolt assembly. The two side plates have the same structure and are arranged oppositely, and are respectively arranged at both ends of the frame structure formed by the top plate 11, the back plate 12 and the bottom plate 13. The side plate structure includes an upper connecting member 14 and a lower connecting member 15. The upper connecting member 14 is respectively screwed to the top plate and the back plate, and the lower connecting member is respectively screwed to the bottom plate and the back plate. The upper connecting member and the lower connecting member 15 are screwed together and enclose to form a mounting hole.

[0029] As Figure 2 shown, a fixing block 2 is provided in the housing body 1. The fixing block 2 is integrally formed and made of aluminum alloy. Both ends of the fixing block 2 extend into the mounting hole to facilitate fixed connection with the housing body 1; a closed glue path channel 3 is formed in the fixing block 2. The glue path channel 3 is a blind hole and extends along the axial direction of the fixing block 3. The glue path channel 3 forms a glue inlet 4 on one end face of the fixing block 2. In addition, the glue path channel 3 is also communicated with two glue spraying nozzles 5. The pressurized glue liquid entering through the glue inlet 4 can be sprayed out through the glue spraying nozzles 5. The control element in the glue spraying nozzle 5 is electrically connected to an external controller through an electric wire, and a valve is provided at the glue inlet 4 and is electrically connected to the external controller through an electric wire.

[0030] As Figure 4 shown, it further includes a plurality of heating tubes 21. The fixing block 2 is provided with blind holes for accommodating the heating tubes 21. The heating tubes 21 are embedded and fixed in the blind holes. The heating tubes 21 include heating wires. The fixing block 2 serves as a conductor, and the heating wires can transfer heat to the glue liquid in the glue path channel 2 through the fixing block 2 to heat the glue liquid. As Figure 2 shown, the glue spraying nozzles 5 are arranged facing the opening. It further includes brackets 8 provided corresponding to the glue spraying nozzles 5 one by one. One end of the bracket 8 is fixedly provided on the housing body 1. The other end of the bracket 8 includes a groove surrounding the glue spraying nozzle 5. Specifically, a long hole 9 corresponding to the position of the bracket 8 is provided on the bottom plate 13 of the housing body 1. A screw assembly passes through the long hole 9 and the through hole on the bracket 8 to fixedly set the bracket 8 on the housing body 1, which is convenient for assembly and positioning and has good applicability.

[0031] As Figure 2 and 4As shown, it further includes a cover plate 7. The side wall of the fixing block 2 facing the opening is recessed inward to form a cavity 6 for accommodating electric wires. The upper end of the cover plate 7 is detachably fixed to the fixing block 2 by screws, and the lower end of the cover plate 7 is close to the bottom plate 13 of the housing body 1, so as to mask the cavity 6. Compared with the prior art solution in which accommodating grooves for electric wires are formed inside multiple modules, the arrangement of the cavity 6 in this application can, on the one hand, be used to accommodate electric wires, improving the flatness of the overall appearance; on the other hand, it can also reduce the volume of the fixing block 2, which is beneficial to cost reduction and also convenient for the maintenance of electric wires.

[0032] As Figure 2 and 3 As shown, a corrugated pipe 10 is sleeved outside the electric wire extending out of the hot melt glue gun assembly, and a connector is connected to the end of the electric wire.
