Description

Technical Field

[0001] This application relates to the field of hot melt adhesive heating, and more particularly to a hot melt adhesive heating tank. Background Technology

[0002] Hot melt adhesive, a type of malleable binder, is solid at room temperature but melts into a viscous liquid upon heating. Currently, hot melt adhesives are primarily used in efficient and environmentally friendly bonding and adhesion applications. Most hot melt adhesive equipment is self-heating, meaning that hot melt sticks or other forms of hot melt adhesive are placed into the container and automatically heated before use. However, this method typically involves directly mounting the heating source onto the adhesive container, posing a risk of burns to workers who may accidentally touch the heat source.

[0012] By adopting the above technical solution, the cavity is used to install the heating wire, thereby improving the stability of the heating wire on the barrel.

[0013] Preferably, the heating wire is arranged in a wavy, annular shape along the side wall of the barrel.

[0014] By adopting the above technical solution, the heating wire is arranged in a wavy ring along the side wall of the barrel, which facilitates the improvement of the uniformity of the heating range of the heating wire.

[0015] Preferably, the heating wire is spirally arranged along the side wall of the barrel.

[0016] By adopting the above technical solution, the heating wire is spirally arranged along the side wall of the barrel, which improves the uniformity of the heating range of the heating wire.

[0019] Preferably, the side wall of the barrel is provided with a partition block located between the top cover and the connector seat.

[0020] By adopting the above technical solution, the separator is used to isolate the temperature between the barrel body and the connector, preventing high temperature from affecting the plug harness.

[0021] Preferably, the upper end of the tubing is provided with a positioning block located above the upper cover.

[0022] By adopting the above technical solution, the positioning block is easy for workers to install or disassemble.

[0023] Preferably, the base has a positioning groove on the side facing the receiving chamber for inserting the dispensing end of the tube.

[0024] By adopting the above technical solution, the positioning groove improves the stability of the hose and facilitates its placement.

[0025] In summary, this application can offset the effects of environmental heat dissipation in real time during continuous operation, thereby improving the viscosity stability of hot melt adhesive; ensure rapid heating of the hot melt adhesive inside the hose while maintaining temperature uniformity throughout the entire section, avoiding localized overheating or curing of the hose; and reduce the impact of heating wire heating on joints and other components, ensuring structural stability during use.

They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] This application discloses a hot melt adhesive heating tank. (Refer to...) Figure 1 and Figure 2The device includes a base 1, a barrel 2 mounted on the base 1, and a heating component 5 installed inside the barrel 2. The barrel 2 has a receiving chamber 3, and an inlet communicating with the receiving chamber 3 is located on the top surface of the barrel 2. A glue tube 4 for loading hot melt adhesive is located inside the receiving chamber 3. The bottom of the glue tube 4 has an outlet for hot melt adhesive to flow out, and the top surface of the glue tube 4 has an inlet for hot melt adhesive to enter. The base 1 has a positioning groove on the side facing the outlet of the glue tube 4 for insertion into the outlet, thus avoiding obstruction of the glue tube 4's outlet. After the hot melt adhesive is placed inside the glue tube 4, the heating component 5 heats the glue tube 4, providing real-time temperature replenishment. To facilitate the removal of the glue tube 4, a positioning block 11 is fixed to the upper end of the glue tube 4, located above the top cover 9. In this embodiment, two positioning blocks 11 are symmetrically arranged to facilitate the insertion or removal of the glue tube 4.

[0032] Reference Figure 1 and Figure 2 The outer wall of the barrel body 2 is fitted with a connector 6 that connects to the heating assembly 5. The heating assembly 5 includes a heating wire 51 and a thermocouple 52 installed inside the side wall of the barrel body 2. The thermocouple 52 is connected to the connector 6 by welding. In this embodiment, the thermocouple 52 is located at the top of the barrel body 2 and on the side of the heating wire 51 closest to the connector 6. The thermocouple 52 is used for temperature feedback. An installation groove 8 for installing the thermocouple 52 is provided inside the side wall of the barrel body 2 to improve the stability of the thermocouple 52 on the barrel body. In specific implementation, the thermocouple 52 is electrically connected to the controller, which facilitates the controller to receive the information feedback from the thermocouple 52 in real time. In this embodiment, the heating wire 51 is electrically connected to the controller, which is used by the controller to control the heating wire 51 to heat the barrel body 2, and at the same time, it is convenient for the operator to control the temperature of the barrel body 2, thereby controlling the temperature received by the hose 4. A cavity is provided inside the side wall of the barrel body 2 to accommodate the heating wire 51, which improves the stability of the heating wire 51 on the barrel body 2. The heating wire 51 is spirally arranged along the side wall of the barrel 2 and then wrapped around the outer wall of the rubber tube 4 to even out the heating range inside the barrel 2; or the heating wire 51 is arranged in a wave shape along the side wall of the barrel 2, and the wave-shaped heating wire 51 is arranged in a ring along the barrel 2 to ensure the uniformity of heating of the barrel 2.

[0033] Reference Figure 1 and Figure 2 To improve the stability of connector 6, a connector seat 7 for positioning connector 6 is fixedly installed on the outer wall of the barrel body 2, and connector 6 is installed on connector seat 7. To improve the stability of the connection between connector 6 and thermocouple 52, a top cover 9 is installed at the upper end of the barrel body 2. The top surface of the top cover 9 has a through hole communicating with the receiving chamber 3 for inserting the rubber tube 4 into the barrel body 2. In this embodiment, the top cover 9 is fixedly installed on the barrel body 2 by bolts. In actual implementation, the top cover 9 can be installed by fitting or snap-fit ​​connection.

[0034] Reference Figure 1 and Figure 2 In order to improve the stability of the connector 6 in subsequent use, the side wall of the barrel 2 is provided with a partition block 10 located between the top cover 9 and the connector seat 7. The partition block 10 is mainly used to isolate the heat transferred from the barrel 2 to the connector seat 7, reducing the possibility that the temperature of the barrel 2 is too high and will affect the normal use of the connector 6.

[0035] The implementation principle of the hot melt adhesive heating bucket in this application embodiment is as follows: hot melt adhesive is placed into the adhesive tube 4, and then the adhesive tube 4 is placed into the bucket body 2. The bucket body 2 is heated by the heating wire 51, thereby heating the hot melt adhesive in the adhesive tube 4. The bucket body 2 can replenish the temperature of the adhesive tube 4 in real time, ensuring uniform heating, improving the melting efficiency and quality of the hot melt adhesive, reducing the possibility of uneven heating of the hot melt adhesive in the adhesive tube 4, and making it convenient for workers to use.
