Description

Technical Field

[0001] The utility model belongs to the technical field of coating production, in particular to an extrusion device for coating production. Background Art

[0002] Icing is a widespread phenomenon in nature, especially in low temperature and high humidity environments. In various fields such as aviation, electric power transportation, communications, and ground transportation, icing has a very adverse effect on industrial facilities including transportation systems, telecommunications systems, and energy systems, often causing catastrophic safety problems and huge economic losses. In related technologies, constructing passive anti-icing / de-icing materials and surfaces that can repel water droplets, inhibit ice formation, reduce ice adhesion strength, and have zero energy consumption is also one of the most economical and effective methods to prevent icing. In the process of producing anti-ice adhesion coatings, extrusion processing is often required through a screw extruder.

[0003] For example, the Chinese patent with publication number CN215791632U discloses an extrusion device for nano coating production, including an extrusion device body, the extrusion device body including a base and a screw extruder arranged on the base, the extrusion device body is provided with an adjustable feeding mechanism, the adjustable feeding mechanism includes a feeding swivel arranged on the screw extruder, a feeding container arranged on the feeding swivel, a slow motor fixedly installed on the feeding container, a stirring rod arranged on the inner side of the feeding container, a positioning frame fixed on the side wall of the feeding container, an adjustment table movably installed outside the feeding container, a displacement block arranged in the adjustment table and an external combination frame fixed thereto. The extrusion device for nano coating production has a simple overall structure, and can be adjusted accordingly to meet the feeding requirements of different directions, and the structure is stable and reliable after the adjustment is completed. At the same time, the device is very convenient and safe to operate, so it is convenient to promote and use.

[0004] This patent has some shortcomings when in use, such as: the device in this patent only sets a stirring mechanism in the feeding container, and uses the rotation of the stirring mechanism to avoid material blockage at the feeding pipe. In the actual production process, due to the relatively large mass of the feeding container and the material in the container, the device lacks a corresponding support force sharing device, so that the weight of the material above the extruder is concentrated on the feeding pipe, and the feeding pipe is subjected to greater stress. The feeding pipe is still prone to blockage, causing the extruder to be unable to discharge materials normally. In addition, in order to avoid the problem of its own large weight, the feeding container in the device has a relatively small capacity, requiring the operator to add materials frequently and continuously, and the overall production process is relatively cumbersome and inefficient. In view of this, we propose an extrusion device for coating production. Utility Model Content

[0005] The purpose of the utility model is to provide an extrusion device for coating production to solve the problems raised in the above background technology.

[0006] In view of this, the utility model provides an extrusion device for coating production, comprising:

[0040] See also Figure 1 - Figure 5 As shown, this embodiment provides an extrusion device for coating production, comprising:

[0041] A base 1, an extruder body 2 is installed on the upper surface of the base 1, side plates 3 are symmetrically fixed on both sides of the base 1, and support plates 4 are fixed on the upper surfaces of the two side plates 3, a raw material barrel 5 is symmetrically arranged directly above the support plate 4, a plurality of support columns 6 are fixed on the lower surface of the raw material barrel 5, and the bottom ends of the support columns 6 are fixed to the upper surface of the support plate 4;

[0042] A U-shaped tube 11 is located directly below the two raw material barrels 5, and the two top feed ports of the U-shaped tube 11 are respectively plugged and installed at the discharge ports on the lower surfaces of the two raw material barrels 5. A through tube 12 is fixed in the middle and lower position of the U-shaped tube 11, and the bottom of the through tube 12 is fixed to the feed port of the extruder body 2 by bolts;

[0043] Two stirring components, the two stirring components are respectively located in the two raw material barrels 5 and are used to stir the raw materials in the raw material barrels 5;

[0044] Two mounting plates 16 are symmetrically arranged and fixedly mounted on the lower surface of the support plate 4. The two mounting plates 16 are respectively located on both sides of the through tube 12. The inner cavity of the through tube 12 is rotatably connected with a cross bar 14, and the two ends of the cross bar 14 respectively penetrate the inner wall of the through tube 12 and rotatably cooperate with the mounting plates 16 on both sides. A bearing seat 17 is fixed on the inner side of the mounting plate 16 on one side, and the cross bar 14 is coaxially connected with the bearing seat 17. The mounting plate 16 on the other side is fixedly mounted with a second motor 18 on the outer side wall, and the output shaft of the second motor 18 penetrates the outer wall of the mounting plate 16 on this side and is coaxially connected to the cross bar 14. A plurality of spikes 15 evenly arranged are fixed on the cross bar 14 and located at the inner cavity of the through tube 12.

[0045] Among them, before using the device, the operator first injects raw materials into the inner cavities of the two raw material barrels 5, and then starts the extruder body 2 and the stirring components on the two raw material barrels 5. At this time, the operator opens one of the control valves 13 on the U-shaped tube 11 and starts the motor 2 18. The raw materials in the raw material barrel 5 on the upper side of the control valve 13 open and begin to slide along the U-shaped tube 11 into the inner cavity of the through tube 12 and further enter the inner cavity of the extruder body 2 to be processed and extruded. In this process, the stirring component continuously stirs the raw materials in the inner cavity of the raw material barrel 5 to prevent the raw materials from agglomerating in the inner cavity of the raw material barrel 5 and clogging at the discharge port on the lower surface of the raw material barrel 5. Further, the motor 2 18 works, the output shaft of the motor 2 18 rotates and drives the cross bar 14 to rotate, and the multiple spikes 15 located in the through tube 12 rotate, so that the raw materials in the inner cavity of the through tube 12 can pass through the through tube 12 more quickly to enter the extruder. The inner cavity of the main body 2 and the plurality of spikes 15 will further break up and differentiate the raw materials in the inner cavity of the through tube 12 to avoid blockage of the raw materials in the inner cavity of the through tube 12. In addition, the side plates 3, support plates 4 and a plurality of support columns 6 in the device can provide good support for the two raw material barrels 5 to avoid the raw material barrels 5 and the raw materials in the inner cavity of the raw material barrels 5 from exerting a large pressure on the through tube 12 due to their own excessive gravity, thereby damaging the through tube 12. In the present application, the extruder main body 2 is the existing public technology of those skilled in the art, and the present application will not describe it in too much detail. The coating raw materials that finally enter the extruder main body 2 are discharged from the extrusion port of the extruder main body 2 under the action of the extruder main body 2; further, when the raw materials in one of the raw material barrels 5 are insufficient, the operator can open the control valve 13 on the other side and close the control valve 13 on that side. At this time, the control valve 13 on the other side starts to discharge the material.

[0046] By providing side plates 3, support plates 4 and a plurality of support columns 6, the support plates 4 are supported by the two side plates 3, and the two raw material barrels 5 are supported by the support plates 4 and the plurality of support columns 6, so that the weight of the two raw material barrels 5 and the raw materials in the raw material barrels 5 can be evenly distributed, and the extrusion force generated by the larger gravity is prevented from being excessively concentrated at the connection between the extruder body 2 and the through pipe 12, thereby ensuring the stability of the device during operation. In addition, by providing two raw material barrels 5 and using the two raw material barrels 5 for feeding, the device can realize uninterrupted feeding while reducing the tediousness of frequent feeding by the operator. At the same time, by providing a stirring assembly in the raw material barrel 5, and providing a cross bar 14 and spikes 15 in the through pipe 12, the stirring assembly and the cross bar 14 and the spikes 15 are rotated, so that when the raw material flows between the raw material barrel 5 and the U-shaped tube 11 and the through pipe 12, the agglomeration and blockage can be avoided, thereby ensuring the feeding stability of the device.
