Description

Technical Field

[0001] The utility model relates to the field of nozzles, and particularly relates to an edge-type nozzle structure. Background Technique

[0002] Nozzles are designed to work under a variety of different spraying conditions. Therefore, a suitable nozzle needs to be selected to achieve the best working performance during use. The characteristics of nozzles are mainly reflected in the spray type of the nozzle, that is, the shape formed when the liquid leaves the nozzle orifice and its operating performance. The naming of nozzles is divided into fan-shaped, conical, liquid column flow, air atomization, and flat nozzles according to the spray shape. Among them, conical nozzles are further divided into two categories: hollow conical and solid conical.

[0003] When performing mold-making work, a nozzle is required to feed the rubber material. However, when applied to medical products, due to the relatively special structure of medical products and the particularly high requirements for appearance, after the existing nozzles work, obvious gate marks will be left on the products, and at the same time, the filling balance of the nozzles cannot be guaranteed, resulting in the inability to well meet the requirements during the processing of medical products.

[0004] Therefore, it is necessary to propose an edge-type nozzle structure to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide an edge-type nozzle structure, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

The back of the servo motor is fixedly connected with a gear through a first rotating shaft. The gear meshes with a second gear. A bearing seat is fixedly connected to the inner cavity of the feed pipe. The crushing ring is rotatably connected to the inner cavity of the bearing seat. The outer wall of the fixed pile is fixedly connected with a crushing rod.

[0011] Preferably, the connecting nozzle is threadedly connected to the back of the main nozzle housing. The discharge pipe is fixedly connected to the back of the connecting nozzle. The inner cavities of the main nozzle housing, the connecting nozzle, and the discharge pipe are interconnected.

[0012] Preferably, copper sleeves are fixedly connected to the inner walls of the connecting nozzle, the discharge pipe, and the connecting nozzle. Heating coils are wound around the outer walls of the copper sleeves. The heating coils are thermocouples. The heating coils are used to heat and control the temperature of the nozzle when injecting glue. The copper sleeves are used to ensure uniform heating.

A feed pipe 2 is fixedly connected to the center of the front surface of the pretreatment component 1. A crushing ring 7 is rotatably connected to the inner cavity of the feed pipe 2. A filter screen 9 is fixedly connected to the front surface of the feed pipe 2. The pretreatment component 1 is a cavity structure with the front and back communicating with the outside. The pretreatment component 1 communicates with the inner cavities of the main nozzle housing 10 and the feed pipe 2. A second gear is fixedly connected to the back surface of the turntable 3. The back surface of the servo motor 4 is fixedly connected to the gear 5 through a first rotating shaft. The gear 5 meshes with the second gear. A bearing seat 6 is fixedly connected to the inner cavity of the feed pipe 2. The crushing ring 7 is rotatably connected to the inner cavity of the bearing seat 6. A crushing rod is fixedly connected to the outer wall of the fixed pile 8. The connecting nozzle 13 is threadedly connected to the back surface of the main nozzle housing 10. The discharge pipe 14 is fixedly connected to the back surface of the connecting nozzle 13. The inner cavities of the main nozzle housing 10, the connecting nozzle 13, and the discharge pipe 14 communicate with each other. By providing the filter screen 9, the rubber material entering the inner cavity of the feed pipe 2 can be filtered. By starting the provided servo motor 4, the gear 5 can be driven to rotate. The gear 5 can mesh with the second gear, so that the crushing ring 7 can be driven to rotate through the turntable 3. Cooperating with the provided fixed pile 8, the rubber material can be secondary processed, thereby ensuring the accuracy of the rubber material and effectively improving the quality of the finished product.

[0026] As Figure 1 , 3As shown in Figures 3 and 4, an edge-type nozzle structure is provided. A main nozzle housing 10 is fixedly connected to the back surface of the pretreatment assembly 1. A connecting nozzle 13 is provided on the back surface of the main nozzle housing 10. A discharge pipe 14 is provided on the back surface of the connecting nozzle 13. Copper sleeves 11 are fixedly connected to the inner walls of the connecting nozzle 13, the discharge pipe 14, and the connecting nozzle 13. Heating coils 12 are wound around the outer walls of the copper sleeves 11. The heating coils 12 are thermocouples. The heating coils 12 are used to heat the nozzle for injecting glue and control the temperature. The copper sleeves 11 are used to ensure uniform heating. A convex ring 15 is fixedly connected to the back surface of the outer wall of the discharge pipe 14. A runner transfer insert 16 is fixedly connected to the front surface of the inner cavity of the discharge pipe 14. An edge-type TIP structure 17 is installed on the outer wall of the runner transfer insert 16. The runner transfer insert 16 is used to fix the edge-type TIP structure 17. The edge-type TIP structure 17 is used to split the glue. It can be used for medical products.

The servo motor 4 is started to drive the gear 5 to rotate, so that the gear 5 can mesh with the second gear. At this time, the turntable 3 can be driven to rotate. The turntable 3 can drive the crushing ring 7 to rotate in the inner cavity of the bearing seat 6. The crushing ring 7 and the fixed pile 8 cooperate to perform secondary treatment on the glue. After the treatment is completed, it only enters the inner cavity of the main nozzle housing 10. The temperature is controlled by the heating coils 12 and the copper sleeves 11. Then it enters the inner cavity of the edge-type TIP structure 17 through the runner transfer insert 16. Finally, it flows into the mold cavity. After cooling and pressure holding, the mold is opened to take out the product, thus completing the production of the product.
