Description

Technical Field

[0001] This utility model relates to the field of coated valve body technology, specifically to a high-efficiency circulating heating module assembly. Background Technology

[0002] Thin-film coating valves are widely used in electronic circuit board protection (such as conformal coating), lithium battery electrode coating, semiconductor packaging, and other fields. Their core function is to form a uniform thin film through non-atomized spraying, improving coating accuracy and material utilization. The viscosity of certain adhesives varies with temperature, requiring a circulating feeding system and a heater structure to ensure high efficiency and stable temperature response. Existing heating tanks, by increasing the size of the adhesive flow channel, do not significantly improve heating efficiency. Changing the flow channel structure significantly increases processing costs, but the results are not ideal. Increasing the flow channel length inevitably leads to dead angles and cavities caused by multiple bends in the flow channel. Therefore, a heating module component with a simple structure and improved heating efficiency is needed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a novel high-efficiency circulating heating module assembly to solve the problem of poor heating efficiency in existing coated valve body heating module assemblies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency circulating heating module assembly for circulating heating of glue in a heating tank includes a heating rod, a spiral heating tank, a heating sleeve, and an outer shell. The spiral heating tank has a through mounting hole along its central axis, and the heating rod passes through the mounting hole of the spiral heating tank. The spiral heating barrel has a spiral annular groove along its outer periphery, and the heating sleeve is sleeved on the outside of the spiral heating barrel to cooperate with the spiral annular groove to form an adhesive passage; There is a gap between the inner side of the heating sleeve and the outer side of the spiral heating barrel; the outer shell is fitted onto the outside of the heating sleeve; an outlet pipe and an inlet pipe are respectively provided at both ends of the spiral heating barrel, and both the outlet pipe and the inlet pipe are connected to the spiral annular groove.

[0005] Furthermore, a fixing seat is provided at each end of the spiral heating barrel, and the two fixing seats are provided with positioning grooves on the side close to each other to fit the end of the spiral heating barrel.

[0006] Furthermore, each of the two fixing seats is provided with at least one first screw hole that penetrates through itself and extends to the end of the spiral heating barrel. A first screw is provided in the first screw hole. The fixing seat and the spiral heating barrel are connected by inserting the first screw into the first screw hole of the fixing seat and the spiral heating barrel.

[0007] Furthermore, each end of the outer casing is provided with at least one second screw hole that penetrates itself and extends to the fixing base along its periphery. A second screw is provided in the second screw hole. The outer casing and the fixing base are connected by inserting the second screw into the second screw holes of the outer casing and the fixing base.

[0008] Furthermore, a mounting base is provided on the lower side of the fixed base at the lower end of the spiral heating barrel. The mounting base is provided with at least one third screw hole that penetrates itself and extends to the fixed base. A third screw is provided in the third screw hole. The mounting base and the fixed base are connected by inserting the third screw into the third screw holes of the mounting base and the fixed base.

[0009] Furthermore, at least one sealing groove is provided at both ends of the spiral heating barrel along its circumference, and the sealing groove is filled with a sealing rubber ring.

[0010] Furthermore, each end of the heating sleeve is provided with at least one fourth screw hole that penetrates itself and extends to the spiral heating barrel along its circumference. A fourth screw is provided in the fourth screw hole. The heating sleeve and the spiral heating barrel are connected by inserting the fourth screw into the fourth screw hole of the heating sleeve and the spiral heating barrel.

[0011] Furthermore, the inlet pipe is located at the bottom of the spiral heating barrel, with one end connected to the bottom end of the spiral annular groove, and the other end passing through the heating sleeve and protruding from the outer surface of the outer shell.

[0012] Furthermore, the upper part of the spiral heating barrel is provided with a detection port, and a sensor is installed in the detection port.

[0013] Furthermore, the gap is greater than 0.06 mm and less than 0.1 mm.

[0014] Compared to existing technologies, the advantages of this invention are that, by adopting the above solution, the structure is simple and suitable for use with a coating valve body in a circulating heating system. The outlet and inlet pipes at the upper and lower ends of the spiral heating barrel are connected to both ends of the spiral annular groove, and a heating rod is inserted into the spiral heating barrel, with a heating sleeve fitted over the outside of the barrel. During use, the adhesive enters through the bottom inlet pipe and flows upwards along the spiral annular groove on the outer circumference of the spiral heating barrel, exiting through the outlet pipe. During this flow, the heating rod in the middle of the spiral heating barrel heats it, and the adhesive spiral slowly ascends around the heating rod. There is a gap between the inner side of the heating sleeve and the outer side of the spiral heating barrel. A very small amount of external glue falls back along this gap and then rises again with the glue, achieving sufficient and uniform heating. Compared with the previous pipe method, this increases the glue heating contact area, improves heating efficiency, and makes the glue heated more thoroughly and evenly. In terms of heating effect, as the spiral ring groove of the spiral heating barrel gradually rises, the temperature can rise uniformly, with good temperature transfer. Within a certain heating barrel volume, the heat transfer area is larger, the pressure loss is smaller, and the surface convection heat transfer coefficient is higher. Moreover, the structure is simple and easy to maintain, making it highly valuable for market applications. Attached Figure Description

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0019] One embodiment of this utility model is as follows: Figure 1 , 2 As shown, this high-efficiency circulating heating module assembly is used to circulate and heat the glue in the heating tank. It includes a heating rod 1, a spiral heating tank 2, a heating sleeve 3, and an outer shell 4. The spiral heating tank 2 has a through mounting hole along its central axis, and the heating rod 1 passes through the mounting hole of the spiral heating tank 2. The spiral heating barrel 2 has a spiral annular groove 21 along its outer periphery, and the heating sleeve 3 is sleeved on the outside of the spiral heating barrel 2 to cooperate with the spiral annular groove 21 to form an adhesive passage. There is a gap between the inner side of the heating sleeve 3 and the outer side of the spiral heating barrel 2; the outer shell 4 is sleeved on the outer side of the heating sleeve 3; the two ends of the spiral heating barrel 2 are respectively provided with an outlet pipe 22 and an inlet pipe 23, and both the outlet pipe 22 and the inlet pipe 23 are connected to the spiral annular groove 21.

[0020] This high-efficiency circulating heating module is suitable for use in circulating heating systems with coated valve bodies. It increases the contact area and contact time between the heating barrel and the medium while facilitating control of processing precision, thereby improving heating efficiency. The outlet pipe 22 and inlet pipe 23 at the upper and lower ends of the spiral heating barrel 2 are respectively connected to the two ends of the spiral annular groove 21. The heating rod 1 is inserted into the spiral heating barrel 2, and then the heating sleeve 3 is fitted onto the outside of the spiral heating barrel 2. During use, the adhesive enters from the bottom inlet pipe 23 and flows upward along the spiral annular groove 21 on the outer periphery of the spiral heating barrel 2, exiting from the outlet pipe 22. During the flow, the heating rod 1, located in the middle of the spiral heating barrel 2, heats it. The adhesive spirals around the heating rod 1 and slowly climbs upward. Due to the heating... There is a gap between the inner side of the sleeve 3 and the outer side of the spiral heating barrel 2. A very small amount of external glue falls back along this gap and then rises again with the glue, achieving sufficient and uniform heating. Compared with the previous pipe method, this increases the glue heating contact area, improves heating efficiency, and makes the glue heating more sufficient and uniform. At the same time, in terms of heating effect, as the spiral ring groove 21 of the spiral heating barrel 2 gradually rises, the temperature can rise uniformly, with good temperature transfer. Within a certain heating barrel volume, the heat transfer area is larger, the pressure loss is smaller, the surface convection heat transfer coefficient is higher, and the structure is simple and easy to maintain.

[0023] In this embodiment, as Figure 2 , 3 As shown, both of the fixing seats 24 are provided with at least one first screw hole that passes through themselves and extends to the end of the spiral heating barrel 2. A first screw 25 is provided in the first screw hole. The fixing seat 24 and the spiral heating barrel 2 are connected by inserting the first screw 25 into the first screw hole of the fixing seat 24 and the spiral heating barrel 2.

First, the heating rod 1 is inserted into the through hole of the spiral heating barrel 2, and then it is sleeved onto the end of the spiral heating barrel 2 through the positioning groove on the fixing seat 24. Then, the first screw 25 is screwed into the first screw holes of the fixing seat 24 and the spiral heating barrel 2, so that the fixing seat 24 and the spiral heating barrel 2 can be detachably connected.

Each of the upper and lower ends of the outer shell 4 is provided with four second screw holes. The second screws 41 are screwed into the second screw holes of the outer shell 4 and the fixing seats 24 to make the outer shell 4 and the fixing seats 24 detachably connected.

[0027] In this embodiment, as Figure 2 As shown, a mounting base 5 is provided on the lower side of the fixed base 24 located at the lower end of the spiral heating barrel 2. The mounting base 5 is provided with at least one third screw hole that penetrates itself and extends to the fixed base 24. A third screw 51 is provided in the third screw hole. The mounting base 5 and the fixed base 24 are connected by inserting the third screw 51 into the third screw hole of the mounting base 5 and the fixed base 24.

[0028] Specifically, the mounting base 5 is located on the lower side of the fixed base, and the third screw 51 is screwed into the third screw hole of the mounting base 5 and the fixed base to connect the mounting base 5 and the fixed base. The mounting base 5 facilitates the installation of the heating module assembly.

[0029] In this embodiment, as Figure 2 , 4 As shown, at least one sealing groove 26 is provided at both ends of the spiral heating barrel 2 along its periphery, and the sealing groove 26 is filled with a sealing rubber ring 27.

[0030] Specifically, a sealing groove 26 is provided at each of the upper and lower ends of the spiral heating barrel 2, and the sealing ring 27 protrudes from the sealing groove 26 to seal the heating sleeve 3 with the spiral heating barrel 2.

[0032] Specifically, the sealing grooves 26 at both ends of the spiral heating barrel 2 are located inside the fourth screw hole. After the heating sleeve 3 is fitted onto the spiral heating barrel 2 and sealed by the sealing ring 27, the fourth screw 31 is screwed into the fourth screw hole of the heating sleeve 3 and the spiral heating barrel 2, so that the heating sleeve 3 and the spiral heating barrel 2 can be detachably connected.

[0033] In this embodiment, as Figure 2 As shown, the inlet pipe 23 is located at the bottom of the spiral heating barrel 2, one end of which is connected to the bottom end of the spiral annular groove 21, and the other end passes through the heating sleeve 3 and protrudes from the outer surface of the outer shell 4.

[0034] Specifically, the inlet pipe 23 is located at the bottom of the spiral heating barrel 2, and the outlet pipe 22 is located at the top of the spiral heating barrel 2.

[0038] Specifically, the heat insulation cover 7 is located between the heating sleeve 3 and the outer shell 4, and is secured by two fixing seats 24 to prevent heat from dissipating outward.

[0039] In this embodiment, as Figure 2 As shown, the gap is greater than 0.06 mm and less than 0.1 mm.
