[0002] Drying refers to the process of removing the solvent and retaining the solid content in a certain way. It usually refers to the process of passing hot air to evaporate and take away the water in the material. According to the three ways of heat transmission, heat conduction, heat convection, and heat radiation, there are also three corresponding ways of drying: drum drying, hot air drying, and far-infrared drying. At the same time, glass ink, which can be printed on glass and can adhere firmly, is divided into high-temperature glass ink, tempered glass ink, glass baking ink, low-temperature glass ink, and ordinary glass ink according to the processing temperature.

[0003] However, during the use of the prior art, there is an uneven distribution of air volume and temperature, which can easily cause uneven heating of the glass ink, resulting in poor drying effect, and then it is necessary to increase the drying time or dry it multiple times. In the process of increasing the drying time or drying it multiple times, the production efficiency is greatly reduced, and the energy consumption is greatly increased.

[0004] Therefore, a screen printing circulating heating and drying system is provided to solve the above problems. Summary of the invention

[0005] The purpose of the utility model is to address the problem that during use of the prior art, there is uneven distribution of air volume and temperature, which easily causes uneven heating of the glass ink, resulting in poor drying effect, and then the need to increase the drying time or dry it multiple times. In the process of increasing the drying time or drying it multiple times, the production efficiency is greatly reduced and the energy consumption is greatly increased.

[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0007] A screen printing circulating heating and drying system comprises a shell, both sides of which are movably connected with baffles and are threadedly connected with bolts at the clamping points, one side of the baffle is movably connected with an installation box, both sides of the surface of one side of the installation box are penetrated and clamped with hoses, the extraction end of the hose is fixedly connected with a conversion tube, one side of the conversion tube is movably connected with a seal, one side of the seal is provided with a through hole, and a heating resistor wire is fixedly connected to the inner arc wall of the through hole, the other side of the seal is movably connected with a three-way pipe, one side of the upper surface of the shell is fixedly connected with a bracket, the top of the bracket is fixedly connected with a fan, and the air inlet of the fan is fixedly connected to the air outlet of the three-way pipe.

[0008] As a preferred technical solution of the present application, an air duct is fixedly connected to the middle of the inner top wall of the shell, both ends of the air duct are fixedly connected to air pipes, and both sides of the air pipe are fixedly connected to exhaust pipes.

[0009] As a preferred technical solution of the present application, an air supply pipe is fixedly connected to the middle of the surface of one side of the air duct, one end of the air supply pipe is inserted through and clamped on the shell, and is fixedly connected to the air outlet of the fan.

[0010] As a preferred technical solution of the present application, there are several exhaust ducts, which are evenly and equidistantly distributed on both sides of the duct, and air outlet holes are opened at the bottom of the outer arc surface of the exhaust duct, and the air outlet holes are evenly and equidistantly distributed on the exhaust duct.

[0011] As a preferred technical solution of the present application, the bottom of the outer arc surface of the exhaust duct is located at the edge of the exhaust duct and is fixedly connected to a support rod, the bottom end of the support rod is fixedly connected to an obstruction member, and the upper surface of the obstruction member is provided with an arched protrusion.

[0012] As a preferred technical solution of the present application, grooves adapted to the screen drying machine table are provided on both sides of the lower surface of the shell, and connecting bolts are threadedly connected to the bottom of both side surfaces of the shell.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the scheme of this application:

[0015] By setting the fan, heating resistor wire, hose, exhaust pipe and obstruction, the staff can more conveniently inject hot air into the internal glass ink of the shell for drying. In the process of hot air discharge, the hot air is dispersed by the obstruction, so that the hot air discharged from a single air outlet is evenly dispersed to the surroundings. At this time, the synchronous air outlet of multiple air outlets can form a uniform air outlet, so that the temperature and air volume inside the shell are more uniform, so as to improve the drying efficiency of the glass ink, and effectively avoid uneven temperature and air volume, and the occurrence of local undrying. The problem of uneven air volume and temperature distribution in the use of the prior art is solved, which easily causes uneven heating of the glass ink, and then makes the drying effect poor, and then needs to increase the drying time or multiple drying. In the process of increasing the drying time or multiple drying, the production efficiency is greatly reduced, and the energy consumption is greatly increased. BRIEF DESCRIPTION OF THE DRAWINGS
