Furthermore, the internal flow guiding structure and nozzle of the hose are difficult to clean, easily leading to glue residue or blockage. Replacing the nozzle is also inconvenient. In addition, some heating devices have unreasonable nozzle cavity designs, resulting in uneven heat distribution and low outlet temperature, further affecting the performance of the mixed glue. To solve the above problems, a glue mixing hose heating device is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a heating device for a mixed glue tube, including a hexagonal sleeve 1 and a heat-conducting bundle tube 2. The hexagonal sleeve 1 is used to fix the device on the glue outlet of the glue applicator, and the inner wall of the hexagonal sleeve 1 is provided with a raised edge 1a.

[0025] The heat-conducting tube 2 is located at the bottom end of the hexagonal sleeve 1 and is connected to the hexagonal sleeve 1. It is used to transport and heat the mixed adhesive. The heat-conducting tube 2 consists of an outer sleeve 21 and an inner sleeve 22. A cavity 23 is formed between the outer sleeve 21 and the inner sleeve 22 to provide installation space for the heat-conducting wire 3. The heat-conducting tube 2 has a connecting part 24 that slides into the spray nozzle 5 to realize the connection and sealing with the spray nozzle 5, ensuring that the mixed adhesive enters the spray nozzle 5 smoothly.

[0026] The heat-conducting wire 3 is set in the cavity 23 and spirals on the outer wall of the inner sleeve 22. The spiral arrangement can make the inner sleeve 22 heat more evenly, thereby heating the mixed adhesive inside evenly, avoiding the problem of solidification or reduced bonding effect caused by uneven heating of the mixed adhesive, and improving the performance of the mixed adhesive.

[0027] Temperature controller 4 is installed on the outer wall of heat-conducting tube 2 and electrically connected to heat-conducting wire 3. It is used to adjust the heating temperature of heat-conducting wire 3. It can precisely control the heating temperature according to different types of mixed adhesives and ambient temperature, ensuring that the mixed adhesive is used at a suitable temperature and further improving the bonding effect.

[0028] The glue spray head 5 is detachably mounted at the bottom of the heat-conducting tube 2 and connected to the bottom box of the heat-conducting tube 2 via two fixing parts 6. It is used to spray out the heated mixed glue. The internal cavity of the glue spray head 5 is tapered and gradually decreases in diameter from one end of the heating tube to the glue outlet. Compared with the traditional heating cavity, which is mostly cylindrical, this tapered and gradually decreasing design makes it less likely for heat to accumulate at both ends of the cavity, avoiding the situation that the temperature at the middle glue outlet is too low. This ensures that the temperature of the mixed glue is uniform when it is sprayed out of the glue outlet, thus improving the bonding quality.

[0029] The carrier sleeve 7 penetrates the hexagonal sleeve 1 and extends into the inner sleeve 22 for mounting the spiral guide frame 8. The top edge of the carrier sleeve 7 has a skirt 71, which fits against the raised edge 1a and has a sealing ring 72 on the top. Through the cooperation with the raised edge, the carrier sleeve 7 is sealed and positioned to ensure the sealing of the mixed adhesive during the conveying process and prevent leakage. The carrier sleeve 7 can be slid out of the hexagonal sleeve 1 to facilitate cleaning of the spiral guide frame 8 and the inner wall of the inner sleeve 22, avoiding mixed adhesive residue or blockage and ensuring long-term stable operation of the device.

[0030] The spiral guide frame 8 is set at the bottom of the bearing sleeve 7 and fits against the inner wall of the inner sleeve 22. It is used to guide the flow of the mixed adhesive in the heat-conducting tube 2, so that the mixed adhesive can fully contact the inner sleeve 22 and be heated evenly, thereby improving the heating effect.

[0031] Specifically, refer to Figure 2-3 The fastener 6 includes a fastening block 61 disposed on the outer wall of the outer sleeve 21. The fastening block 61 has an inclined surface to facilitate the fitting of the fastening plate 63. A connecting plate 62 disposed on the outer wall of the spray nozzle 5 is used to connect the fastening plate 63. The fastening plate 63 is disposed on the outer wall of the connecting plate 62 and fits over the fastening block 61. When the fastening plate 63 passes the fastening block 61, it deforms under the guidance of the inclined surface of the fastening block 61 and gradually fits over the outer wall of the fastening block 61. Once it is completely fitted over the outer wall of the fastening block 61, the spray nozzle 5 can be fixed. This fixing method is simple to operate and can quickly replace the spray nozzle 5, improving production efficiency.

[0032] Working principle

[0033] In use, the external adhesive supply device delivers the mixed adhesive through the hexagonal sleeve 1 into the heat-conducting tube 2; the temperature controller 4 controls the heating of the heat-conducting wire 3. Since the heat-conducting wire 3 is spirally coiled on the outer wall of the inner sleeve 22, the inner sleeve 22 is heated evenly, thereby heating the mixed adhesive inside evenly; when the mixed adhesive flows in the heat-conducting tube 2, the spiral guide frame 8 guides the mixed adhesive to fully contact the inner sleeve 22, further ensuring the uniformity of heating and avoiding insufficient solidification time and reduced bonding effect of the mixed adhesive in low-temperature environments;

[0034] The heated adhesive mixture enters the spray nozzle 5 through the connection part 24 of the heat-conducting tube 2. The tapered and gradually changing cavity design inside the spray nozzle 5 ensures uniform heat distribution and avoids low outlet temperature. The adhesive mixture is evenly sprayed out from the spray nozzle 5 for bonding operations.

[0035] When it is necessary to clean the inside of the device, the bearing sleeve 7 can be slid out to remove the spiral guide frame 8, and the spiral guide frame 8 and the inner wall of the inner sleeve 22 can be cleaned to prevent the mixed glue residue or blockage. If it is necessary to replace the glue spray head 5, simply remove the fixing plate 63 from the fixing block 61 to quickly replace the glue spray head 5. The operation is simple.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
