Description

Technical Field

In addition, the existing hot gate nozzles do not take into account the demand for ultra-large flow, which may lead to low glue application efficiency and glue waste. These shortcomings will lead to poor glue flow control and reduced overall glue application quality. For this reason, a fan-shaped hot gate nozzle is proposed. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, a fan-type gate hot nozzle provided by an embodiment of the utility model includes a hot nozzle body 01, and the bottom outer side and the top inner side of the hot nozzle body 01 are both provided with positioning areas, which helps to ensure the correct installation and positioning of other components. It also includes:

[0024] The sealing nozzle head 02 cooperates with the positioning area on the inner side of the top of the hot nozzle body 01 to ensure the precise position of the sealing nozzle head 02, which is very important for controlling the flow of glue; the sealing nozzle head 02 is provided with a positioning area to further provide positioning function for other components.

[0025] The heat-conducting nozzle core 03 achieves a more uniform temperature distribution by configuring the nozzle core, which is crucial to ensuring the fluidity of the glue and the quality of the product; the heat-conducting nozzle core 03 is provided with a square gate 31, which provides a larger glue outlet cross-section.

[0026] The positioning seat 04 is fixedly arranged at the bottom of the heat conducting nozzle 03 and cooperates with the positioning area in the sealing nozzle 02. The positioning seat 04 is provided with a positioning groove to further ensure the correct installation and stability of the components.

[0027] The flat torpedo nozzle 05 has a nozzle tip 51 which is fan-shaped and designed for super large flow, which can directly reach the product without a water outlet, thereby improving the gluing efficiency and reducing waste; the nozzle tip of the flat torpedo nozzle 05 is close to the part 53 which is waterfall-shaped, making the glue flow smoother, helping to improve the flow path of the glue, reducing blockage and improving the gluing quality; the flat torpedo nozzle 05 has inclined surfaces 52 on both sides of the nozzle tail, which drain the flow and reduce the shear force, thereby helping to protect the properties of the glue and reduce the degradation of the glue caused by shearing.

[0028] The positioning seat 2 06 is fixedly connected to the flat torpedo nozzle core 05, and the positioning seat 2 06 is adapted to the positioning groove to ensure the stability and accuracy of the entire assembly.

[0029] In the embodiment of the present invention, the sealing nozzle head 02 is assembled in the positioning area on the inner side of the top of the hot nozzle body 01, and the thermal conductive nozzle core 03 is assembled with the sealing nozzle head 02 through the mutual cooperation of the positioning seat 1 04 and the positioning area inside the sealing nozzle head 02, and the flat torpedo nozzle core 05 is assembled with the sealing nozzle head 02 through the mutual cooperation of the positioning seat 2 06 and the positioning groove, thereby completing the installation of the fan-shaped gate hot nozzle.

[0030] like Figure 4 and Figure 5 As shown, as a preferred embodiment of the utility model, the positioning seat 2 06 is provided with four reinforcing ribs 07. This design allows the flat torpedo mouth core 05 to be more evenly stressed and less prone to deformation, thereby enhancing the durability and stability of the structure.

[0031] like Figure 3-5 As shown, as a preferred embodiment of the utility model, the flat torpedo nozzle core 05 is provided with a protruding positioning seat 2 06 at the nozzle tail, which is convenient for installation and maintenance, while ensuring the correct position of the nozzle tip 51 and the flow path of the glue.

[0032] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
