Description

Technical Field

[0001] This utility model relates to the field of gluing machine technology, and in particular to a heating structure for a gluing machine. Background Technology

[0002] In order to change the physical properties of the glue and make it more suitable for automated production and achieve better process results, the glue needs to be heated before use.

[0003] Chinese Patent Authorization Announcement No.: CN218423847 U, Authorization Announcement Date: February 3, 2023. This utility model relates to a glue dispensing structure for a glue applicator, including a hollow heating tube, an electric heating wire, a dispensing tube, a detachable head, and a cover plate. The dispensing tube is located at the bottom of the hollow heating tube, and a detachable head is fixedly connected to the outer side of the bottom end of the dispensing tube by a locking screw. A cross-shaped partition plate is located at the bottom of the detachable head, and an arc-shaped glue dispensing groove is formed through the bottom of the detachable head near the bottom end of the cross-shaped partition plate. The drawback of this technical solution is that the glue, heated by the electric heating wire on the outside of the heating tube, is prone to uneven heating (external heat and internal cold), which affects the glue application effect.

[0004] In summary, the existing heating structure has the drawback of uneven heating of the adhesive. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing heating structures in terms of uneven heating of adhesives, and provides a heating structure for a glue applicator that improves heating uniformity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A heating structure for a gluing machine, comprising: The heating element has a feed inlet at the top and a discharge outlet at the bottom. The feed tube sheet is detachably connected to the feed inlet, and the feed tube sheet is connected to the feed tube. The heating coil has a spiral limiting groove on the outer side of the heating tube, and the heating coil is sleeved with the spiral limiting groove. The feed tube plate is connected to a support rod, and several guide rings are provided and connected to the support rods. The guide rings are placed between the recesses of the spiral limiting groove. The discharge short pipe is detachably connected to the discharge port. Insulation sleeve one, which is connected to the heating tube.

[0007] Material is input into the heating tube through the feed pipe at the upper inlet and output through the discharge short pipe at the lower end. Both the feed pipe plate and the discharge short pipe are detachable and connected to the heating tube for easy assembly and maintenance of accessories. The spiral limiting groove is a structure with an inwardly recessed surface and a protruding inner wall, which allows the heating coil to be placed closer to the core of the material flow within the heating tube. Simultaneously, in conjunction with the guide ring connected to the inner cavity support rod of the heating tube, the position of the heating coil is staggered with the guide ring, making it easier for the material to "spread out" within the heating tube, resulting in uneven heating and overflow from the heating structure, affecting the glue application quality. An insulation sleeve maintains the temperature inside the heating tube. This achieves the effects of improving the heating uniformity of the glue application machine's heating structure, ensuring glue application quality, and facilitating the assembly and maintenance of accessories.

[0008] Preferably, the feed pipe includes a main pipe and several branch pipes. The feed pipe plate has several branch inlets, one end of each branch pipe is connected to a branch inlet, and the other end of each branch pipe is connected to the main pipe. The main pipe is used for adding adhesive, and the branch pipes are used to distribute the added adhesive, ensuring that the adhesive is added evenly and smoothly into the heating pipe, preventing "blockage" and "interaction" of the adhesive. This achieves the effect of improving the feeding smoothness and heating efficiency of the heating structure.

[0009] Preferably, the inner wall of the guide ring is connected to the support rod, and the cross-sectional shape of the guide ring is conical. The connection between the support rod and the inner hole of the guide ring, with its arc-shaped edge, allows for smoother flow under the inclined surface of the conical shape, ensuring even heating and smoothing of the colloid. This achieves the effect of improving the heating uniformity and smoothness of the structure.

[0010] Preferably, the heating tube is fitted with an outer sleeve, and the heating coil is placed between the outer sleeve and the heating tube. The outer sleeve is positioned between the heating tube and the insulation sleeve, and a fixing screw is inserted into the outer sleeve. The heating tube has mounting screw holes, and the fixing screw is threaded into the mounting screw holes. The outer sleeve, which covers the heating tube, provides insulation while protecting and limiting the heating coil. Furthermore, the fixing screw facilitates disassembly and maintenance. This achieves the effect of improving the heating insulation performance and assembly stability of the heating structure.

[0011] Preferably, the wall of the discharge port is provided with internal threads, and the upper outer side of the discharge short tube is provided with external threads that are compatible with the internal threads. The discharge short tube is threadedly connected to the discharge port. The discharge short tube is screwed into the discharge port through the threaded connection, allowing for quick installation and removal of the discharge short tube, which facilitates maintenance of the heating tube's inner cavity. This improves the ease of assembly and maintenance of the heating structure.

[0012] Preferably, a limiting ring is connected to the discharge port, and the end face of the discharge short tube is in contact with the limiting ring. Several anti-slip protrusions are connected to the outer side of the discharge short tube. The discharge port is connected to the end of the discharge port near the inner cavity of the heating tube via the limiting ring to limit the installation of the discharge short tube, thereby improving assembly accuracy. In addition, several vertically arranged anti-slip protrusions are connected to the outer side of the discharge short tube to prevent slippage during disassembly and assembly. This achieves the effect of improving the assembly and maintenance accuracy and convenience of the heating structure.

[0013] Preferably, the discharge short pipe is connected to a discharge tube plate, which has several branch discharge ports. The outlet of the discharge short pipe is connected to the discharge tube plate, allowing the heated glue to be discharged through each branch discharge port. This achieves a stable and smooth discharge effect from the heating mechanism.

[0014] Preferably, the discharge short pipe is fitted with an insulation sleeve II. The insulation sleeve II is used to insulate the heated adhesive and prevent it from losing temperature immediately before discharge, thus improving its usability. This enhances the heating and insulation efficiency of the heating structure.

[0015] The beneficial effects of this utility model are: improving the heating uniformity of the heating structure of the gluing machine; ensuring the quality of gluing; facilitating the assembly and maintenance of accessories; improving the heating smoothness of the structure; improving the assembly and maintenance accuracy and convenience of the heating structure; and improving the heating and heat preservation efficiency of the heating structure.
