Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, specifically to a hot air circulation energy-saving structure for a drying oven in a glue coating production line. Background Technology

[0002] A drying oven is an industrial drying equipment constructed from welded steel profiles and thin plates. It is primarily used in industrial and research fields such as material drying, resin curing, pharmaceuticals, and electronic component processing. Its structure combines robustness and aesthetics. The working chamber is equipped with sample shelves or mobile carts. The space between the outer shell and the working chamber is filled with insulation materials such as aluminum silicate fiber and polyester foam to enhance thermal insulation performance. Forced air convection via a blower ensures temperature uniformity, and air circulation is regulated using valves on the top of the blower.

[0003] However, in the existing technology, when drying the glued parts, hot air is blown to dry and cure the glue. However, the hot air is not circulated during the drying process, so the hot air is discharged after blowing once. Moreover, when there is too much moisture in the glue, it is necessary to blow hot air for a longer time, which easily leads to waste and is not energy-saving and environmentally friendly.

The gear is fixedly mounted on the output end of the motor, and the gear meshes with the gear ring.

[0006] Furthermore, the piping assembly includes an installation pipe, a filter tank, a round pipe, two corrugated pipes, two fixing pipes, and two buckle plates.

[0007] Furthermore, the fixing assembly includes two movable plates, two rectangular openings, two push plates, and a bidirectional pneumatic rod. The two movable plates are respectively fixedly installed on two fixed pipes. The two rectangular openings are respectively opened on the outer surface of the mounting box. The two push plates are respectively fixedly installed on the top of the two movable plates. The bidirectional pneumatic rod is fixedly installed on the outer surface of the mounting box, and the two output ends of the bidirectional pneumatic rod are respectively fixedly connected to the two push plates.

[0008] Furthermore, an installation opening is provided on the outer wall of the installation box, and a sealing door is provided inside the installation opening. The sealing door is fixedly connected to the installation box by fasteners.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention, through the setting of a replaceable component, addresses the issue of excessive moisture in the adhesive during drying. In this case, a bidirectional pneumatic rod is activated, extending and pushing a push plate. The push plate moves a moving plate within a rectangular opening, which in turn moves a fixed tube away from the circular tube. The fixed tube then moves a buckle plate away from the circular tube, compressing the corrugated tube and causing it to retract. This unlocks the circular tube, stops the bidirectional pneumatic rod, and starts the motor. The motor drives a gear to rotate, which meshes with a gear ring. This meshing rotation of the gear ring causes the circular plate to rotate, which in turn rotates the slide plate. The circular plate then rotates the slide rail, which slides within the rail. After the circular plate rotates 180 degrees, the motor stops. The positions of the pipe, installation pipe, and filter tank are swapped. The bidirectional pneumatic rod is restarted to reset the buckle plate, clamping and connecting the installation pipe and filter tank. If the hot air is blown and dried at this time, the recovered hot air carries moisture evaporated from the glue. When the hot air is introduced into the filter tank through the recovery pipe, the lime in the filter tank reacts with the moisture and releases high temperature. Before the hot air enters the air inlet pipe, it carries the heat emitted by the lime, further increasing the temperature of the blown hot air. This further heats and dries the glue, accelerating the drying speed. It has the advantages of circulating the hot air and increasing the drying temperature and efficiency when heating and drying glue with high water content, thus saving drying energy consumption.

[0014] This invention features a circulation system. Upon opening the drying chamber, the glued parts are placed sequentially on the ventilation plate. The drying chamber is then closed, and the external hot air equipment is activated via the control cabinet. Hot air is blown into the inlet pipe of the hot air equipment box and guided into the top cover. The top cover diffuses the hot air and blows it into the drying chamber, heating and drying the parts inside. The blown hot air then enters the side cover, which gathers the hot air and pours it into the recovery pipe. The recovery pipe discharges the hot air into a circular pipe, through which the still relatively hot air is reintroduced into the inlet pipe for circulation. This system offers the advantages of hot air infusion and guidance, heating and drying of glued parts, and hot air recycling. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides, for example Figures 1-4As shown, a hot air circulation energy-saving structure for a drying box in an adhesive coating production line includes a drying component 1, a replacement component 2, and a circulation component 3. The drying component 1 is used to dry the coated parts. The replacement component 2 is mounted on the drying component 1 for replacing pipes and increasing the temperature. The circulation component 3 is mounted on the drying component 1 for circulating hot air. The replacement component 2 includes a rotating component, a pipe component, and a fixing component. The rotating component is mounted on the drying component 1, the pipe component is mounted on the rotating component, and the fixing component is mounted on the rotating component. The rotating component includes a mounting box 201, a slide rail 202, a sliding plate 203, a circular plate 204, a gear ring 205, a motor 206, and a gear 207. Mounting box 201 is mounted on drying assembly 1. Slide rail 202 is fixedly mounted on the inner wall of mounting box 201. Slide plate 203 is slidably mounted inside slide rail 202. Circular plate 204 is fixedly mounted on slide plate 203. Gear ring 205 is fixedly mounted on one outer wall of circular plate 204. Motor 206 is fixedly mounted on the inner wall of mounting box 201. Gear 207 is fixedly mounted on the output end of motor 206. Gear 207 meshes with gear ring 205. More specifically, during drying, if the adhesive contains a large amount of moisture, a bidirectional pneumatic rod 217 is activated. The bidirectional pneumatic rod 217 extends and pushes push plate 216 to move. Push plate 216 drives moving plate 214 at rectangular opening 21. 5. Moving plate 214 drives fixed tube 212 to move away from round tube 210. Fixed tube 212 drives buckle plate 213 to move and disengage from round tube 210. When fixed tube 212 moves, it squeezes bellows 211, causing bellows 211 to retract. At this time, round tube 210 is unlocked, bidirectional pneumatic rod 217 is stopped and motor 206 is started. Motor 206 drives gear 207 to rotate. Gear 207 meshes with gear ring 205. Gear ring 205 rotates due to meshing and drives round plate 204 to rotate. Round plate 204 drives slide plate 203 to rotate. Slide plate 203 slides in slide rail 202. After round plate 204 rotates 180 degrees, motor 206 stops. At this time, round tube 210, installation tube 208 and filter tank 2 The position of 09 is reversed, and the bidirectional pneumatic rod 217 is restarted to reset the buckle plate 213, clamping and connecting the installation pipe 208 and the filter tank 209. If the hot air is blown and dried at this time, the recovered hot air carries the moisture evaporated from the glue. When the hot air is introduced into the filter tank 209 by the recovery pipe 305, since the filter tank 209 is filled with lime, the lime reacts when it comes into contact with the moisture and emits high temperature. Before the hot air enters the air inlet pipe 303, it will carry the heat emitted by the lime, which will further increase the temperature of the blown hot air, further heating and drying the glue, accelerating the drying speed. It has the advantages of circulating the hot air and improving the drying temperature and efficiency when heating and drying glue with high water content, saving drying energy consumption.

[0022] In addition, the piping assembly includes an installation pipe 208, a filter tank 209, a round pipe 210, two corrugated pipes 211, two fixed pipes 212, and two buckle plates 213. The installation pipe 208 is fixedly installed on the round plate 204, the filter tank 209 is threadedly installed on the installation pipe 208, the round pipe 210 is fixedly installed on the round plate 204, the two corrugated pipes 211 are both fixedly installed on the inner wall of the installation box 201, the two fixed pipes 212 are respectively fixedly installed on the two corrugated pipes 211, and the two buckle plates 213 are respectively fixedly installed on the two fixed pipes 212.

[0023] In addition, the fixing assembly includes two movable plates 214, two rectangular openings 215, two push plates 216, and a bidirectional pneumatic rod 217. The two movable plates 214 are respectively fixedly installed on two fixed tubes 212. The two rectangular openings 215 are respectively opened on the outer surface of the mounting box 201. The two push plates 216 are respectively fixedly installed on the top of the two movable plates 214. The bidirectional pneumatic rod 217 is fixedly installed on the outer surface of the mounting box 201, and the two output ends of the bidirectional pneumatic rod 217 are respectively fixedly connected to the two push plates 216.

[0024] In addition, an installation opening is provided on the outer wall of the installation box 201, and a sealing door is provided inside the installation opening. The sealing door is fixedly connected to the installation box 201 by fasteners.

[0025] like Figure 1 As shown, in some embodiments, the drying assembly 1 includes a base 101, a drying chamber 102, and a control cabinet 103. The drying chamber 102 is fixedly installed on the top of the base 101, the control cabinet 103 is fixedly installed on the top of the base 101, and the mounting box 201 is fixedly installed on the top of the drying chamber 102. The top of the drying chamber 102 is provided with a first vent, and three second vents are provided on one side of the outer wall of the drying chamber 102.

[0026] like Figure 1As shown, in some embodiments, the circulation assembly 3 includes a vent plate 301, a top cover 302, an air inlet pipe 303, two side covers 304, and a recovery pipe 305. The vent plates 301 are evenly distributed inside the drying chamber 102. The top cover 302 is fixedly installed on the top of the drying chamber 102. The air inlet pipe 303 is fixedly installed on the top of the top cover 302. The two side covers 304 are fixedly installed on one outer wall of the drying chamber 102. The recovery pipe 305 is fixedly installed on the two side covers 304. One end of the recovery pipe 305 is fixedly connected to the mounting box 201. More specifically, when the drying chamber 102 is opened, the glued parts are placed sequentially on the vent plate 301. At this time, the drying chamber is closed. The drying chamber 102 starts the external hot air equipment through the control cabinet 103, blowing hot air into the air inlet pipe 303 of the hot air equipment box. The hot air enters the air inlet pipe 303 and is guided into the top cover 302. The top cover 302 diffuses the hot air and blows it into the drying chamber 102 to heat and dry the parts inside the drying chamber 102. The blown hot air enters the side cover 304, which gathers the hot air and pours it into the recovery pipe 305. The recovery pipe 305 discharges the hot air into the round pipe 210. The round pipe 210 then reintroduces the still relatively hot air into the air inlet pipe 303 for circulation. This has the advantages of injecting and guiding hot air, heating and drying glued parts, and recycling hot air.

[0027] In some embodiments, a one-way valve is fixedly installed on the mounting box 201, the one-way valve is fixedly connected to the air inlet pipe 303, and the recovery pipe 305 is configured as a three-way valve.

[0028] Working principle:

[0029] Step 1: Hot air blowing. Open the drying chamber 102 and place the glued parts on the ventilation plate 301 in sequence. At this time, close the drying chamber 102 and start the external hot air equipment through the control cabinet 103 to blow hot air into the air inlet pipe 303. The hot air enters the air inlet pipe 303 and is guided into the top cover 302. The top cover 302 diffuses the hot air and blows it into the drying chamber 102 to heat and dry the parts in the drying chamber 102. The blown hot air enters the side cover 304. The side cover 304 gathers the hot air and pours it into the recovery pipe 305. The recovery pipe 305 discharges the hot air into the round pipe 210. The round pipe 210 then reintroduces the still relatively hot air into the air inlet pipe 303 for circulation blowing.

[0030] Step Two: Replace the pipes. During drying, if the adhesive contains a lot of moisture, activate the bidirectional pneumatic rod 217. The bidirectional pneumatic rod 217 extends and pushes the push plate 216 to move. The push plate 216 drives the moving plate 214 to move within the rectangular opening 215. The moving plate 214 drives the fixed tube 212 to move away from the round tube 210. The fixed tube 212 drives the buckle plate 213 to move and disengage from the round tube 210. When the fixed tube 212 moves, it squeezes the bellows 211, causing the bellows 211 to retract. At this time, the round tube 210 is unlocked, the bidirectional pneumatic rod 217 is stopped, and the motor 206 is started. The motor 206 drives the gear 207 to rotate. The gear 207 meshes with the gear ring 205, causing the gear ring 205 to rotate and drive the round plate 204 to rotate. The round plate 204 drives... The slide plate 203 rotates and slides within the slide rail 202. After the circular plate 204 rotates 180 degrees, the motor 206 stops. At this time, the positions of the circular tube 210, the mounting tube 208, and the filter tank 209 are swapped. The bidirectional pneumatic rod 217 is restarted to reset the buckle plate 213, clamping and connecting the mounting tube 208 and the filter tank 209. If the hot air is being blown and dried at this time, the recovered hot air carries moisture evaporated from the glue. When the hot air is introduced into the filter tank 209 by the recovery pipe 305, the lime in the filter tank 209 reacts when it comes into contact with the moisture and releases high temperature. Before the hot air enters the air inlet pipe 303, it carries the heat emitted by the lime, further increasing the temperature of the blown hot air, further heating and drying the glue, and accelerating the drying speed.
