Description

Technical Field

[0001] The invention relates to a semiconductor electric heating film spraying processing device for the inner wall of a fast heating glass tube, which can perform semiconductor electric heating film spraying processing on the inner wall of the heating tube. Background Art

[0002] The production process of electric heating film tubes includes spraying semiconductor electric heating film on the glass tube wall, and then placing electrodes on the semiconductor electric heating film layer to form a heating tube assembly. With the continuous improvement of the semiconductor electric heating film formula and the glass tube body, fast heating glass tubes with fast heating effect have begun to be used.

[0003] The existing rapid heating glass tube has a broad market prospect, but due to the difficulty of mass production, its production cost remains high, which makes the existing rapid heating glass tube relatively limited in practical application. The existing equipment for spraying semiconductor electric heating film onto the inner wall of the glass tube mainly includes a heating furnace, a glass tube fixing tool, and a spray gun, and the spray gun is connected to the external semiconductor electric heating film liquid source by a pump connection. During the spraying process: the glass tube fixing tool with the glass tube installed is transferred to the heating furnace through the corresponding driving mechanism, and then the spray gun is extended to the corresponding glass tube, so as to effectively spray the semiconductor electric heating film material onto the inner wall of the glass tube under the heating environment, thereby forming a heating tube with a semiconductor electric heating film. After the semiconductor electric heating film is sprayed, the glass tube and the spray gun are reset respectively, and then removed after the glass tube is cooled. Such spraying equipment has the defect of extremely low production efficiency during actual use. In order to improve production efficiency, glass tube fixing tools that can fix multiple glass tubes at the same time have begun to be put into use. In this way, although the production efficiency has been improved to a certain extent, after the glass tubes are sprayed with semiconductor electric heating films, they still need to be reset in the glass tube fixing tool and the spray gun respectively, and the glass tubes need to be cooled and taken out before they can enter the production of the next batch of heating tubes. The production efficiency is still relatively low.

[0004] The present invention aims to provide a rapid heating glass tube inner wall semiconductor electric heating film spraying processing equipment, which can realize the rapid connection of the spraying process, thereby greatly improving the spraying efficiency of the inner wall semiconductor electric heating film of the heating glass tube, thereby effectively reducing the production cost of the rapid heating glass tube, so as to enhance the market competitiveness of its products.

[0027] 5) The present invention can adjust the position of the limit plate to adjust the compression force of the compression spring, thereby effectively adjusting the spraying pressure of the electric heating film material, so as to further improve the controllability of the electric heating film spraying of the present invention.

[0028] 6) A spherical abutment portion is provided on the outer side of the connecting shaft of the present invention. Under the elastic force of the compression spring, the inner end of the baffle plate is sealed and abutted against the discharge section of the injection hole, while the middle part of the baffle plate abuts against the spherical abutment portion of the connecting shaft to prevent the electrothermal film liquid from leaking along the gap between the baffle plate and the connecting shaft, thereby effectively further ensuring the practical effect of the invention.

The third driving mechanism 504 drives the glass tube clamping claw 503 to move inward, so that the glass tubes 7 respectively pass through the feed holes 102 and enter the heating furnace 1. Then, the fourth driving mechanism 602 drives the spray gun 601 to move inward, so that the nozzles of the spray gun 601 respectively pass through the corresponding glass tubes 7. The spray gun 601 is started to spray the electrothermal film liquid uniformly onto the inner wall of the glass tube 7. In this process, the first driving mechanism 3 drives the rear side of the support frame 2 to enter the heating furnace 1. The electrothermal film spray gun 601 is driven by the first driving mechanism 3 to drive the rear side of the support frame 2 to enter the heating furnace 1.

[0039] During the spraying process, multiple glass tubes 7 can be clamped between the same group of horizontal clamping plates 501, and then the glass tubes 7 are driven to penetrate into the heating furnace 1 respectively. Thereafter, the spray gun 601 is moved inward to penetrate into the corresponding glass tubes 7 respectively; the electrothermal film liquid is evenly sprayed onto the inner wall of the glass tube 7 by starting the spray gun 601.

The liquid inlet end of the coolant inlet pipe 37 is connected to an external coolant collection pool through a corresponding circulation pump, and the liquid outlet end of the coolant outlet pipe 38 is connected to the external coolant collection pool. Under the action of the coolant, the support tube 6011 can be prevented from being significantly deformed due to excessive heat, and the electrothermal film liquid can be cooled during the transportation process, thereby effectively ensuring the spraying effect of the electrothermal film.

[0057] The nozzle 6012 includes a nozzle body 60121 with a fixing groove, and a nozzle cover 60122 with the spray hole 29 is fixedly connected to the outer side of the nozzle body 60121.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
