Description

Technical Field

[0001] This utility model relates to the field of coating machine extrusion heads, and in particular to a coating machine extrusion head with a heating structure. Background Technology

[0002] The extrusion head of a coating machine is the core component of coating equipment. It is used to uniformly extrude and apply coating to the surface of the substrate. Its structure typically includes an inlet, an extrusion chamber, and an outlet. By precisely controlling the flow rate and pressure of the coating, it ensures that the coating thickness is uniform and consistent.

[0003] During the coating feeding process, the poor flowability of the coating, coupled with the increased temperature of the external environment, may cause coating blockage and hinder normal operation. In addition, coatings applied directly to the surface of the device require subsequent drying, which increases the working pressure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating machine extrusion head with a heating structure, which ensures the stability of the device's operation and improves the convenience of subsequent processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A coating machine extrusion head with a heating structure includes:

[0007] The lower die head is used for lower side support. The top of the lower die head is fixedly connected to the upper die head. The front side of the bottom end of the upper die head is provided with a discharge slot. The interior of the lower die head is provided with a buffer slot. A flipping component is installed inside the buffer slot. Multiple feeding components are installed on the rear side of the lower die head to agitate the internal coating. An air cavity is provided inside the lower die head. A heating rod is fixedly connected inside the air cavity to heat the inside of the air cavity.

[0008] A drying air frame is used for the lower rear end of the lower mold head. A transmission air frame is fixedly connected to the front end of the drying air frame. The outer front end of the transmission air frame penetrates into the interior of the air cavity. A fan is fixedly connected to the left side of the drying air frame. A drying transmission assembly is installed at the bottom end of the lower mold head to achieve the solidification of the coating.

[0009] Furthermore, the drying and conveying assembly includes a conveying air duct located at the bottom of the lower die head, with a support frame fixedly connected to both sides of the conveying air duct, and a traction cylinder rotatably connected to the inner side of the support frame to achieve traction support for coating.

[0010] Furthermore, the flipping assembly includes a rotating rod that rotates inside the buffer slot, a rotating roller that is fixedly connected to the outside of the rotating rod, and multiple stirring plates that are evenly fixedly connected to the outside of the rotating roller.

[0011] Furthermore, the multiple feeding assembly includes multiple separate transmission pipes located on the rear side of the top of the lower die head, and a transfer pipe is fixedly connected to the rear end of each separate transmission pipe.

[0012] Furthermore, a feed pipe is fixedly connected to the right side of the transfer pipe for adding coatings.

[0013] Furthermore, the interior of the air cavity is wider at the rear and narrower at the front, and it communicates with the interior of the transmission air duct.

[0014] Furthermore, both sides of the outlet of the transmission duct are fixedly connected with converging baffles to achieve the convergence of the drying airflow.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the coating inside the buffer tank is heated by a heating rod and then transferred to the inside of the buffer tank through multiple separate transmission pipes. The pressure of the transmission agitates the stirring plate, thereby improving the fluidity of the liquid inside the device, preventing blockage, and ensuring the stability of the device's operation.

[0017] 2. In this utility model, air is drawn inward by a fan, thereby accelerating its entry into the drying air frame. The air is then conveyed into the air cavity through the air frame, thereby drawing the high-temperature air inside out through the air duct, thus drying the coating surface and improving the convenience of subsequent processing of the device.

Detailed Implementation

[0024] 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.

[0025] Reference Figure 1 , and 3 and Figure 4 This utility model provides an embodiment of a coating machine extrusion head with a heating structure, comprising: a lower die head 1 for lower side support, an upper die head 2 fixedly connected to the top of the lower die head 1, a discharge slot 19 opened on the front side of the bottom end of the upper die head 2, a buffer slot 15 opened inside the lower die head 1, a flipping component installed inside the buffer slot 15, a multi-feed component installed on the rear side of the lower die head 1 for agitating the internal coating, and an air cavity 16 opened inside the lower die head 1. A heating rod 17 is connected to heat the inside of the air cavity 16. The flipping assembly includes a rotating rod 14 that rotates inside the buffer slot 15. A rotating roller 11 is fixedly connected to the outside of the rotating rod 14. Multiple stirring plates 12 are evenly fixedly connected to the outside of the rotating roller 11. The multi-feed assembly includes multiple split transmission pipes 13 located behind the top of the lower die head 1. A transfer pipe 8 is fixedly connected to the rear end of the split transmission pipe 13. A feed pipe 7 is fixedly connected to the right side of the transfer pipe 8 for adding paint.

[0026] The combined surfaces of the lower die head 1 and the upper die head 2 are tightly attached to the coating surface of the raw material. The raw material moves forward under the guidance of the traction cylinder 4 and the transmission air duct 3 and adheres to the outside of the traction cylinder 4. At the same time, the coating enters the transfer pipe 8 through the feed pipe 7 and is diverted to the buffer trough 15 through multiple split transmission pipes 13. Under pressure, the coating contacts the stirring plate 12, driving the rotating roller 11 to rotate and stir, so that the coating is evenly mixed. After the heating rod 17 is started, it heats the coating in the buffer trough 15, softens it and improves its fluidity, ensuring that the coating is smoothly discharged through the discharge trough 19. This design not only improves the fluidity and coating uniformity of the coating, but also effectively avoids the clogging problem, ensuring the stability and efficiency of the device operation.

[0027] Reference Figure 2 and Figure 4 A drying air frame 9 is used for the lower rear end of the lower die head 1. A transmission air frame 18 is fixedly connected to the front end of the drying air frame 9. The outer front end of the transmission air frame 18 penetrates into the interior of the air cavity 16. A fan 10 is fixedly connected to the left side of the drying air frame 9. A drying transmission assembly is installed at the bottom of the lower die head 1 to achieve the solidification of the coating. The drying transmission assembly includes a transmission air duct 3 located at the bottom of the lower die head 1. Support frames 6 are fixedly connected to both sides of the transmission air duct 3. A traction cylinder 4 is rotatably connected to the inner side of the support frame 6 to achieve the pulling support of the coating. The interior of the air cavity 16 is wider at the back and narrower at the front and communicates with the interior of the transmission air duct 3. Converging baffles 5 are fixedly connected to both sides of the outlet of the transmission air duct 3 to achieve the convergence of the drying airflow.

[0028] After the coating is applied, the heating rod 17 heats the inside of the air cavity 16, raising the air temperature. Then, the fan 10 is started to accelerate the delivery of hot air into the drying air frame 9, and the hot air is introduced into the transmission air duct 3 through the transmission air frame 18. The hot air is concentrated and discharged outward under the action of the converging baffle 5, making uniform contact with the coating surface and achieving rapid drying. This design not only improves the efficiency and uniformity of coating drying, but also enhances the convenience of subsequent processing, ensures rapid curing of the coating surface, and further improves the overall working efficiency and processing quality of the device.

[0029] Working principle: The combined surfaces of the lower die head 1 and the upper die head 2 are in contact with the coating surface of the raw material. The raw material passes through the inner side of the traction cylinder 4 and the transmission air duct 3, pulling the raw material forward so that it adheres to the outside of the traction cylinder 4. At this time, the raw material is driven, and the coating is added into the interior of the transfer pipe 8 through the feed pipe 7. It is also distributed into the interior of the buffer tank 15 through multiple split transmission pipes 13. The pressure generated by this contacts the stirring plate 12, thereby rotating and stirring the rotating roller 11 to agitate the internal liquid. At the same time, the heating rod 17 is activated to heat the coating inside the buffer tank 15. This softens the material, ensuring it can be smoothly discharged outwards through the discharge trough 19 for coating. As the coating is fed, the heating rod 17 heats the inside of the air chamber 16, raising the internal air temperature. The fan 10 is then activated to accelerate the air transfer into the drying air frame 9. The air enters the drying air frame 9 and is transferred into the transfer air frame 18. The air draws the hot air inside the air chamber 16 into the transfer air duct 3, where it is then gathered outwards by the gathering baffle 5, thus contacting the coating surface and drying it evenly, improving the convenience of subsequent processing.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
