[0033] ​​​​​​​​The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figures 1 to 9 The paint stripper shown includes a housing 1, which has a paint stripping station 21 and a washing station 22 adjacent to the paint stripping station 21. A suction device 3 is provided on the upper side of the paint stripping station 21, and a first filter housing 4 is connected to both the suction device 3 and the paint stripping station 21. The washing station 22 has a second filter housing assembly 6 connected to the suction device 3. This invention, by setting the paint stripping station and washing station in close proximity, not only improves production efficiency by further reducing the time spent between the paint stripping and washing processes, but also reduces the time operators spend in contact with the paint stripper. Furthermore, the suction device, the first filter housing, and the second filter assembly reduce the risk of operators directly contacting large amounts of paint stripper vapor, and prevent paint stripper from dripping onto the ground and equipment during workpiece transfer, further improving the working environment.

[0035] Since paint removers often have a pungent odor, the suction device installed above the paint remover station can promptly remove the paint remover vapors generated during the process, preventing them from spreading throughout the workshop. This effectively improves air quality and creates a healthier, more comfortable working environment for operators, reducing potential health problems caused by prolonged inhalation of paint remover vapors. The first filter housing connecting the paint remover station and the suction device filters the suction-upflowed mixture of paint remover components, ensuring that the emitted gas meets standards.

[0036] Optionally, in some embodiments, the first filter housing can separate and collect the paint remover from the mixed gas, enabling the paint remover to be recycled and reused, reducing the consumption cost of the paint remover and improving resource utilization. Furthermore, by providing a second filter assembly adjacent to the first filter assembly, a portion of the paint remover vapor is transferred from the outlet of the first filter chamber to the suction device, and a portion of the vapor is transferred from the outlet of the second filter chamber to the suction device, forming a multi-positional filtration structure. The first filter housing above the paint removal station provides a better "smoke collection effect," and the second filter assembly effectively collects or absorbs the steam and smoke generated by the residual heat during the transfer of the workpiece from the paint removal station to the washing station.

[0037] By placing the paint stripping and washing stations close together, workpieces can be quickly transferred to the washing station after paint stripping, achieving a seamless connection between the two processes. This reduces time loss during workpiece transfer, minimizes steam and fumes, shortens operator contact time with paint stripper and reduces risks, and prevents paint stripper from dripping onto the ground or equipment during workpiece transfer. This contributes to improved overall paint stripping efficiency and a smoother, more efficient production process. Because the workpiece can quickly enter the washing stage after paint stripping, any residual paint stripper on the workpiece surface is washed away before it is fully dry and adhered firmly, resulting in a better washing effect. This more thoroughly removes paint stripper and residual impurities from the workpiece surface, ensuring the quality of subsequent workpiece processing.

[0038] like Figures 1 to 5 The illustrated paint stripping machine includes a paint stripping station 21 with a paint stripping tank 211, a first opening 212 located on the upper side of the paint stripping tank 211 for placing a fixture, and a second opening 213 communicating with the first filter housing 4. The paint stripping tank 211 has a slot baffle 2111 located on the upper side of the first opening 212, and a first heating element 2112 for heating the liquid. Furthermore, the slot baffle in the paint stripping tank is located above the first opening for placing the fixture. When a workpiece enters and exits the paint stripping tank through the fixture for paint stripping, the slot baffle effectively prevents the paint stripping agent liquid in the paint stripping tank from splashing out due to shaking or workpiece entry and exit. This reduces the possibility of paint stripping agent dripping onto the ground and causing pollution and corrosion, and also prevents paint stripping agent from splashing onto the operator and harming their health, greatly improving the safety of the operation. At the same time, the slot baffle reduces the direct escape of paint stripping agent vapor, minimizing the area of ​​paint stripping agent vapor diffusion when not in operation.

[0039] The paint stripping tank is equipped with a first heating element for heating the liquid, which heats the paint stripper liquid to a more suitable stripping temperature. A suitable temperature helps accelerate the chemical reaction between the paint stripper and the paint layer on the workpiece surface, thereby removing the paint layer from the workpiece more efficiently, shortening the stripping time for individual workpieces, and improving the overall efficiency of the paint stripping operation.

[0040] The paint stripping tank is provided with a second opening communicating with the first filter housing. During the paint stripping process, the steam generated by the heated paint stripper can enter the first filter housing through the second opening, thereby facilitating the centralized collection and treatment of the paint stripper steam by the first filter housing and preventing the steam from spreading in the workshop environment and causing air pollution. Optionally, in some embodiments, the paint stripper can also be recycled and reused through the filtration effect of the first filter housing, reducing the waste of paint stripper and meeting the requirements of environmental protection and resource conservation.

[0041] The first opening specially used for placing the jig is arranged, so that the operator can conveniently and accurately place the jig loaded with the workpiece on the paint removal tank body to perform the paint removal operation, thereby improving the convenience and accuracy of the operation, facilitating the daily production operation, and facilitating the standardized operation of the paint removal process.

[0042] As shown in Figures 1 to 5 a paint removal machine, the water washing station 22 is provided with a water washing tank body 221, a third opening 222 located on the upper side of the water washing tank body 221 and used for placing the jig, and an ultrasonic assembly 223 located on the water washing tank body 221. The water washing tank body 221 is provided with a second heating member 2211 used for heating the liquid.

[0043] The ultrasonic assembly arranged in the water washing tank body can generate high-frequency vibrations. During the cleaning process, these high-frequency vibrations can form countless micro cavitation bubbles in the water washing liquid. When the bubbles burst, a strong impact force is generated and acts on the surface of the workpiece, which can completely remove some stubborn impurities, fine particles, and paint remover residues left on the surface of the workpiece after paint removal, greatly improving the cleaning effect of the water washing and ensuring that the workpiece can enter the subsequent process in a cleaner state.

[0044] The water washing tank body is provided with a second heating member used for heating the liquid. By heating the water washing liquid, its physical and chemical properties can be changed, such as reducing its surface tension, improving its solubility for dirt, etc. The appropriate temperature also makes the chemical reaction more easily, speeds up the cleaning speed, and makes various pollutants on the surface of the workpiece faster to separate from the workpiece surface into the water washing liquid, thereby effectively shortening the water washing time of a single workpiece, improving the working efficiency of the entire water washing process, and ensuring the efficient operation of the production process.

[0045] The third opening located on the upper side of the water washing tank body and used for placing the jig facilitates the operator to accurately and easily place the jig loaded with the workpiece into the water washing tank body for cleaning operation, facilitates the standardized and normalized water washing operation process, reduces the operation error, and improves the convenience of daily production operation.

[0046] As shown in Figure 2 and Figure 7The first filter housing 4 is provided with a first filter cavity 40 communicated with the paint removal tank 211, a first barrier part 41 communicated with the first filter cavity 40 and contacted with steam, and a first collection assembly 42 for collecting liquid, the first barrier part 41 is used to drive steam to condense into liquid and transfer to the first collection assembly 42, the first collection assembly 42 comprises a reflux groove 421 communicated with the first barrier part 41 and the operation station 2, and a first filter opening 422 communicated with the reflux groove 421 and the first filter cavity 40 respectively, and the reflux groove 421 is arranged in an inclined manner. By arranging the first barrier part, the moving stroke of the paint removal agent steam in the first filter cavity is prolonged, the paint removal agent steam is condensed to form liquid drops, the paint removal agent liquid is transferred to the first collection assembly, the waste caused by directly sucking away a large amount of steam is avoided, the consumption of the paint removal agent is reduced, the number of times of adding the paint removal agent by the operator is reduced, and the paint removal efficiency is further improved and manpower is saved.

[0047] Specifically, the suction device located on the upper side of the paint removal tank and the first filter cavity communicated with the suction device and the paint removal tank are arranged in the housing, thereby forming a relatively complete steam treatment system. The suction device can suck away the paint removal agent steam generated by the paint removal tank, and the first filter housing provides a relatively closed space environment. When the paint removal agent steam contacts the first barrier part, the first barrier part increases the moving stroke of the steam, a part of the steam is attached to the surface of the first barrier part, and then the heat of the steam is lost, so that the condensation phenomenon occurs, and the steam changes from the gaseous state to the liquid state. The first collection assembly collects the liquid condensed by the first barrier part, realizes the recycling of the paint removal agent steam which would be directly wasted, avoids the loss of the paint removal agent in the paint removal tank, and reduces the subsequent demand for supplementing the paint removal agent.

[0048] Further, the first barrier part is arranged to promote the condensation and collection of the paint removal agent steam, the problem of waste of the paint removal agent caused by directly sucking away the steam by the existing steam suction device is solved, the paint removal agent can be recycled, the production cost is reduced, and the use efficiency of the paint removal agent is improved. The steam suction device effectively solves the problem of frequent supplement of the paint removal agent, so that the paint removal work can be more continuous and smooth, the time delay caused by supplementing the paint removal agent is reduced, the paint removal work amount per unit time is improved, and the overall efficiency of the paint removal is improved.

[0049] Further, the reflux groove is located below the first barrier part and communicates with the paint removal tank body, which can effectively collect the paint remover liquid condensed by the first barrier part. After the paint remover vapor condenses into liquid under the action of the first barrier part, it will flow into the reflux groove under the action of gravity, avoiding the situation that the condensed paint remover liquid flows everywhere and cannot be collected, ensuring the effective recovery of the paint remover. Specifically, the reflux groove collects the paint remover that would otherwise be lost, and then returns it to the paint removal tank body through the channel of the reflux groove, realizing the recycling of the paint remover, reducing the waste of the paint remover, improving the utilization rate of the paint remover, and reducing the production cost.

[0050] Specifically, the first filter opening communicates with the reflux groove and the first filter cavity, respectively. On the one hand, part of the paint remover vapor flows through the reflux groove to the first filter cavity, which increases the path of vapor transfer and speeds up the flow of vapor. On the other hand, the paint remover vapor can flow smoothly into the reflux groove after condensing in the first filter cavity, forming an orderly liquid flow path to ensure that the condensed liquid can flow smoothly into the reflux groove for collection. In addition, the inclined reflux groove can block the vapor and reduce the rising speed of the vapor, so that part of the energy of the rising vapor is dissipated and converted into droplets before entering the first filter cavity, and on the other hand, the paint remover forming droplets can be moved from the reflux groove to the operating station.

[0051] As shown in a paint removal machine, Figure 6 The first barrier part 41 is provided with a first barrier part body 411 connected in the first filter cavity 40, a first flap 412 connected on one side of the first barrier part body 411, and a second flap 413 connected on the other side of the first barrier part body 411. The first flap 412 and the second flap 413 are inclined, the first barrier part body 411 is provided with an opening 4111, and the first barrier part body 411 extends in the transverse direction. The side wall of the first filter housing 4 is provided with a first connecting part 43, and the end of the first barrier part body 411 is provided with a first matching part 4112. The first connecting part 43 and the first matching part 4112 are connected, so that the extension direction of the first barrier part 41 intersects with the moving direction of the vapor. Further, the first flap and the second flap are inclined, which increases the contact area and contact time of the paint remover vapor with the first barrier part. When the vapor enters the first filter cavity, it will fully contact the inclined first flap and the second flap. The vapor is more likely to exchange heat during the flow on the surface of the first flap and the second flap, which promotes the condensation of the vapor and helps to improve the condensation efficiency of the paint remover vapor, thereby more effectively converting the vapor into liquid and realizing the recovery of the paint remover and reducing waste.

[0052] Specifically, the first baffle body is provided with an opening, so that when the steam passes through the first baffle body, part of the steam can pass through the opening, forming a complex airflow channel. This not only allows the steam to continuously contact the first baffle body and the first and second flaps during its passage through the first baffle body, but also causes the flow rate and direction of different parts of the steam to change when passing through the opening, further increasing the opportunity for the steam to contact the first baffle, strengthening the condensation process, and improving the recovery efficiency of the paint stripper steam.

[0053] In addition, part of the steam located on the first baffle body can move downward through the opening, avoiding the accumulation of liquid on the first baffle body. The opening can guide the liquid droplets to flow back to the first collection assembly under the action of gravity, reducing the step of manually transferring the cooled paint stripper. Preferably, the first flap 412 and the second flap 413 are arranged in a spreader shape. Further, the first flap 412 and the second flap 413 are symmetrically arranged.

[0054] Specifically, the side wall of the first filter housing is provided with a first connecting portion, and the end portion of the first baffle body is provided with a first matching portion, and the two are connected so that the extension direction of the first baffle intersects the moving direction of the steam. This connection method can make the first baffle more stably installed in the first filter cavity, ensuring that the first baffle will not easily displace or shake under the impact of the steam, which is conducive to the device to continuously and stably perform its functions of condensing and collecting paint stripper, avoiding performance degradation or failure due to loose or displaced parts. Optionally, in some embodiments, the first connecting portion is a groove, and the first matching portion is a protrusion. Optionally, in some embodiments, the first connecting portion is a protrusion, and the first matching portion is a groove. Optionally, in some embodiments, the first connecting portion is a magnetic attraction piece, and the first matching portion is a magnetic attraction piece.

[0055] Specifically, the extension direction of the first baffle intersects the moving direction of the steam, changing the original flow path of the steam, allowing the steam to more fully contact the first baffle, helping to improve the steam treatment effect, further improving the collection and recovery effect of the paint stripper steam, while avoiding the steam being directly sucked away without being fully treated, reducing the waste of paint stripper, and improving the overall work efficiency of the steam suction device. Preferably, the first baffle is arranged in a horizontal direction. Optionally, in some embodiments, when the paint stripper steam enters the first filter cavity, the steam will be guided to various positions of the first filter cavity and contact and condense on the surface of the first baffle due to the vertical extension direction of the first baffle body and the paint stripper steam inlet direction. This design can increase the residence time of the steam in the first baffle body, thereby improving the condensation efficiency.

[0056] Further, the first matching part is arranged along the extending direction of the first barrier part body, the first flap extends away from the second flap, the second flap extends away from the first flap, and the extending directions of the first flap and the second flap are arranged in an eight-shaped manner. Optionally, in some embodiments, when the first flap is located on the upper side of the first barrier part body, the liquid drops formed by the steam inside the first flap will move from the first flap to the first barrier part body and be collected, or move to the opening, and the liquid drops will drip down from the opening; when the first flap is located on the lower side of the first barrier part body, the steam will drip down from the first flap.

[0057] Further, the plurality of first upper barrier parts are arranged on the same horizontal line, and the plurality of first lower barrier parts are arranged on the same horizontal line. In some embodiments, in the vertical direction, the first upper barrier parts and the first lower barrier parts are arranged in a staggered manner, the first upper barrier parts are arranged between two groups of first lower barrier parts in the vertical direction, and the first lower barrier parts are arranged between two groups of first upper barrier parts in the vertical direction. In some embodiments, in the horizontal direction, the first upper barrier parts and the first lower barrier parts are arranged in a staggered manner, and a spacing space is arranged between two first lower barrier parts. The first upper barrier part located on the lower side of the first lower barrier part or on the upper side of the first lower barrier part is arranged on the upper side or the lower side of the spacing space between the two first lower barrier parts. The steam needs to pass through the space between the two adjacent first upper barrier parts and then be transferred to the space between the two adjacent first lower barrier parts, thereby further prolonging the moving distance of the steam.

[0058] Optionally, in the present embodiment, the length of the first barrier part body is close to the length direction of the first filter shell, the width of the first barrier part body is smaller than the width of the first filter shell, the first flap of the first upper barrier part is close to the first flap of the first lower barrier part, the first flap of the first upper barrier part is arranged in parallel with the first flap of the first lower barrier part, the second flap of the first upper barrier part is away from the second flap of the first lower barrier part, and the second flap of the first upper barrier part is arranged in parallel with the second flap of the first lower barrier part. Such arrangement forms a narrow channel between the adjacent first upper barrier part and the first lower barrier part, and the steam passing through the narrow channel will reduce the speed, thereby further prolonging the moving time of the steam in the inner cavity of the steam suction cover shell.

[0059] As Figures 1 to 5The paint removal machine shown, the paint removal tank body 211 is provided with a paint removal tank body supporting part 2113 for supporting the jig, the water washing tank body 221 is provided with a water washing tank body supporting part 2212 for supporting the jig, the paint removal tank body 211 and the water washing tank body 221 are arranged adjacent to each other, the first heating element 2112 is located outside the paint removal tank body 211, and the second heating element 2211 is located outside the water washing tank body 221. The paint removal tank body supporting part provided by the paint removal tank body and the water washing tank body supporting part provided by the water washing tank body can provide stable supporting effect for the jig. When the operator places the jig containing the workpiece into the paint removal tank body or the water washing tank body, the supporting part can ensure that the jig is placed stably, avoid the jig from shaking, tilting or even falling into the tank body during the paint removal or water washing process, ensure the smooth operation of the paint removal and water washing operation, and improve the accuracy and convenience of the operation.

[0060] The paint removal tank body and the water washing tank body are arranged adjacent to each other, so that the workpiece can be transferred to the water washing station for water washing operation very conveniently and quickly after completing paint removal at the paint removal station, the transfer time and distance of the workpiece between the two processes are maximally shortened, the time loss in the production process is reduced, the efficient connection of the entire paint removal and water washing process is helped to realize, and thus the overall production efficiency is improved, and the production can be more smoothly and continuously promoted.

[0061] The first heating element is located outside the paint removal tank body, and the second heating element is located outside the water washing tank body. This external design makes it more convenient for maintenance personnel to operate the heating element when it needs to be repaired or replaced, without the need to enter the complex environment inside the tank body, reduces the difficulty and workload of maintenance, facilitates the daily maintenance and repair of the equipment, and reduces the production stagnation time caused by equipment failure.

[0062] Specifically, in some embodiments, the paint remover may contain a large amount of flammable solvents. Direct heating of the solvent by the first heating element can easily pose a safety hazard, potentially causing a fire or explosion during the heating process. Furthermore, if the first heating element is located inside the paint stripping tank, the paint residue from the workpiece can easily adhere to its surface, hindering heat conduction and leading to localized overheating of the first heating element and excessively high local temperatures within the paint stripping tank. Similarly, if the second heating element is located inside the washing tank, the paint residue from the workpiece can easily adhere to its surface, hindering heat conduction and leading to localized overheating of the second heating element and excessively high local temperatures within the washing tank. Externalizing the first and second heating elements avoids prolonged direct contact between them and the paint remover liquid or washing liquid, reducing potential electrical safety hazards such as short circuits and leakage due to liquid leaks. It also reduces the safety risks of localized overheating and liquid boiling / splashing that could occur if the first and second heating elements were inside the tank, ensuring the personal safety of operators and the normal, safe operation of the equipment.

[0063] like Figure 1 The paint stripper shown includes a purification component 5 on the upper side of the paint stripping station 21, which is connected to the first filter housing 4 and the suction device 3 respectively. Further, the purification component can perform further purification treatment on the paint stripper vapor or condensed liquid that has not been completely treated by the first filter housing. Specifically, during the paint stripping process, some impurities, tiny particles, or other pollutants may be mixed in with the paint stripper vapor. Even after preliminary treatment by the first baffle and the first collection component, some impurities may still remain. The purification component can filter, adsorb, or perform other purification operations on these impurities to ensure that the fluid entering the suction device is purer, improving the quality of the recovered paint stripper and the purity of the emitted gas. This not only helps improve the working environment of the workshop and reduce health hazards to operators, but also meets environmental protection requirements, reduces environmental risks caused by pollutant emissions, and makes the operation of the paint stripper more environmentally friendly.

[0064] Specifically, impurities such as paint stripping powder and metal can accumulate inside the suction device if they enter, affecting its performance and causing problems such as blockage, wear, or corrosion. Over time, this reduces the suction device's efficiency and may even lead to damage, requiring more frequent maintenance or replacement. Purifying the steam with a purification component reduces the amount of impurities entering the suction device, lightens its workload, lowers the risk of damage, extends its lifespan, reduces maintenance costs and downtime, and improves the overall stability and reliability of the paint stripper.

[0065] Optionally, in some embodiments, the purification assembly can be filtering the gas through a filtering device, such as using filters of different sizes, filtering through fiber structures; or neutralizing by passing into a chemical solution, such as using sodium hydroxide alkaline absorbent to neutralize the acidic components in the paint remover vapor, or using absorbents with specific functional groups to react with certain active ingredients in the paint remover, thereby changing its chemical properties, making it easier to handle or discharge later; or through multiple condensation treatments of the paint remover vapor, different boiling point components can be gradually separated, realizing the staged purification and recovery of different substances in the vapor, improving the recovery purity and effect of the paint remover.

[0066] As shown in a paint remover, the first barrier part 41 includes a first upper barrier part 414 and a first lower barrier part 415 arranged in the vertical direction, the first upper barrier part 414 is provided with a plurality of and arranged at intervals, the first lower barrier part 415 is provided with a plurality of and arranged at intervals, the first flap 412 and the second flap 413 of the first upper barrier part 414 are inclined towards the first lower barrier part 414, and the first upper barrier part 414 and the first lower barrier part 415 are staggered. Figure 6 Further, the first upper barrier part and the first lower barrier part are arranged in layers in the vertical direction and staggered, forming a multi-level structure. When the paint remover vapor enters the first filtering cavity, it will flow between the different levels of the first upper barrier part and the first lower barrier part. Due to the staggered arrangement between them, the vapor needs to shuttle in this complex structure, prolonging the residence time of the vapor in the first filtering cavity.

[0067] Specifically, the vapor fully contacts the plurality of spaced first upper barrier parts and first lower barrier parts and their flaps, increasing the contact area and contact opportunities between the vapor and the barrier parts, providing more time and space conditions for condensation of the vapor, allowing the vapor to more fully exchange heat with the barrier parts, thereby significantly improving the condensation efficiency, and further converting more paint remover vapor into liquid, facilitating the recovery and reuse of the paint remover, and reducing waste of the paint remover. Specifically, the first flap and the second flap of the first upper barrier part are inclined towards the first lower barrier part, guiding the vapor to flow orderly between the barrier parts at different levels. This inclined design changes the natural flow path of the vapor, causing it to form a circuitous flow trajectory when passing through the first barrier part, further enhancing the interaction between the vapor and the barrier parts. Of course, in some embodiments, the first flap and the second flap of the first lower barrier part are inclined towards the first upper barrier part.

[0068] Specifically, the first upper barrier part and the first lower barrier part are arranged in a central symmetric manner, and the cavity formed by the first upper barrier part and the cavity formed by the first lower barrier part are arranged opposite to each other.

[0069] As Figure 2 and Figure 4 The second filter assembly 6 is located on the upper side of the water washing tank body 221, and is provided with a second filter cavity 60, a second barrier portion 61 located in the second filter cavity 60 and in contact with the steam, and a second collection assembly 62 in communication with the second barrier portion 61. The second barrier portion 61 is used to drive the steam to condense into liquid and be transferred to the second collection assembly 62. The lower side of the second filter assembly 6 is provided with a second filter assembly opening 63. The second collection assembly 62 includes a second collection portion 621 in communication with the second filter assembly opening 63, and a second collection port 622 in communication with the second collection portion 621. The second barrier portion 61 is inclined from top to bottom and from outside to inside. Specifically, the second barrier portion can drive the steam to condense into liquid and be collected by the second collection assembly. The second filter assembly improves the overall condensation and collection efficiency, further reduces the possibility of the paint stripper steam being directly sucked away by the suction device, thereby more effectively recovering the paint stripper and reducing the waste of the paint stripper.

[0070] Specifically, since the second filter assembly cooperates with the first filter assembly, even if part of the paint stripper steam is not sucked on the first filter shell during the paint stripping process, or the paint stripper steam is scattered during the jig transfer process, the second filter assembly can continue to play a certain role in suction, condensation and collection, ensuring that the transfer of the steam is not affected by the scattering position and the work position transfer position, reducing the risk of a large amount of paint stripper loss due to the limited suction range of a single filter assembly, and ensuring that the paint stripping machine can work continuously and stably.

[0071] In addition, the second filter cavity, the second barrier portion and the second collection assembly in the second filter assembly can more accurately process the steam. When the paint stripper steam contacts the second barrier portion, the second barrier portion increases the moving stroke of the steam, and a part of the steam adheres to the surface of the second barrier portion, thereby causing the heat of the steam to dissipate, resulting in condensation phenomenon, from gaseous state to liquid state. The second collection assembly receives the liquid condensed by the second barrier portion, realizes the recovery of the paint stripper steam that would be directly wasted, avoids its dissipation in gaseous form, and thereby reduces the loss of the paint stripper in the chemical tank and reduces the subsequent demand for replenishing the paint stripper.

[0072] Further, the second filter assembly opening on the lower side of the second filter assembly is in communication with the second collection portion, facilitating the collection of the condensed liquid paint remover. When the paint remover vapor condenses into liquid under the action of the second barrier portion, the liquid will naturally flow into the second collection portion through the second filter assembly opening under the action of gravity, ensuring that the liquid can flow orderly to the second collection portion, avoiding the accumulation of liquid in the second filter assembly, improving the efficiency and convenience of liquid collection, so that the recovered paint remover can be better collected and stored for subsequent reuse. Specifically, the second barrier portion is inclined from top to bottom and from outside to inside. This inclined manner guides the paint remover vapor to flow gradually inward and downward. When the vapor flows in the second filter cavity, due to the inclination of the second barrier portion, the vapor will flow along the surface of the second barrier portion, prolonging the contact time and contact area of the vapor with the second barrier portion.

[0073] Additionally, the vapor will continuously exchange heat with the inclined second barrier portion during the flow process, which is more conducive to the condensation of the vapor, so that more vapor can be converted into liquid, improving the condensation efficiency of the paint remover vapor and reducing the waste of paint remover caused by vapor escape. Specifically, the second collection portion is in a plate structure to facilitate liquid collection and drainage, and the second collection opening is connected to the paint removal tank body through a pipeline to realize the recycling of the paint removal liquid.

[0074] As shown in a paint removal machine, Figure 4 Further, the third flap and the fourth flap are inclined, increasing the contact area of the paint remover vapor with the second barrier portion. When the vapor enters the second filter cavity, it will contact these inclined third and fourth flaps. When the vapor flows on the surface of the third and fourth flaps, its flow path will be lengthened and it will be more fully in contact with the surface of the third and fourth flaps. This helps to increase the heat exchange opportunities of the vapor with the second barrier portion, making it easier for the vapor to condense, thereby converting more vapor into liquid and improving the condensation efficiency of the paint remover vapor.

[0075] Specifically, due to the inclined arrangement of the third and fourth flaps, they can guide the steam to flow along a specific path within the second filtering cavity. This guidance can make the steam form an orderly flow within the second baffle, avoiding the situation that part of the steam is not treated sufficiently and passes through. By guiding the steam flow, it ensures that the steam stays on the surface of the second baffle for a long enough time to fully utilize the condensation function of the second baffle, thereby improving the recovery effect of the paint stripper.

[0076] In addition, the vertically extended structure of the second baffle body is beneficial to the layered treatment of steam. Steam at different heights can contact the third and fourth flaps and the second baffle body at different positions, making the condensation treatment of steam more uniform and efficient, improving the efficiency of the entire second baffle in condensation and collection of paint stripper, and further reducing the waste of paint stripper. Preferably, the third and fourth flaps are arranged in a figure-eight shape. Further, the third and fourth flaps are symmetrically arranged.

[0077] As shown in a paint stripper, Figure 4 The second baffle 61 includes a second front baffle 614 and a second rear baffle 615 arranged in the horizontal direction. The second front baffle 614 is provided with multiple and spaced second front baffles 614, and the second rear baffle 615 is provided with multiple and spaced second rear baffles 615. The third and fourth flaps 612 and 613 of the second front baffle 614 are inclined towards the second rear baffle 615. A second front opening 6141 is provided between two adjacent second front baffles 614 to communicate with the operating station 2. A second rear opening 6151 is provided between two adjacent second rear baffles 615 to communicate with the second front opening 6141 and the second filtering cavity 60. The second front baffle 614 and the second rear baffle 615 are staggered. Further, the second front baffle and the second rear baffle are staggered in the horizontal direction, and the third and fourth flaps of the second front baffle are inclined towards the second rear baffle. This layout increases the contact area and contact opportunity of the paint stripper steam with the second baffle. When the steam enters the second filtering cavity, it will shuttle between the staggered second front baffle and the second rear baffle. Due to the inclination of the third and fourth flaps, the steam will continuously collide with and contact the third and fourth flaps and the second baffle body during the flow process, prolonging the contact time of the steam with the second baffle. The steam flows in this complex structure, making the steam fully exchange heat on the surface of the second baffle at different positions, more easily realizing the transformation from gas to liquid, improving the efficiency of steam condensation into liquid, and further effectively recovering the paint stripper and reducing the waste of paint stripper caused by steam escape.

[0078] Specifically, the second front opening and the second rear opening are arranged to prolong the flow path of the steam in the second filter cavity, guide the steam to flow between different positions of the second baffle part, and the zigzag flow path can uniformly distribute the steam in the second filter cavity, avoiding the straight-line flow of the steam.

[0079] Specifically, the second front baffle part and the second rear baffle part are arranged in a central symmetry manner, and the cavity formed by the second front baffle part and the cavity formed by the second rear baffle part are arranged opposite to each other.

[0080] The third flap of the second front baffle part is close to the third flap of the second rear baffle part, and the third flap of the second front baffle part is arranged in parallel with the third flap of the second rear baffle part. The fourth flap of the second front baffle part is away from the fourth flap of the second rear baffle part, and the fourth flap of the second front baffle part is arranged in parallel with the fourth flap of the second rear baffle part. Such an arrangement forms a narrow channel between the adjacent second front baffle part and the second rear baffle part, and the steam passing through the narrow channel will reduce the speed, further prolonging the moving time of the steam in the second filter cavity.

[0081] A control method of a paint stripping machine, comprising the paint stripping machine as described above, and further comprising a heating device, an ultrasonic cleaning device, and an interactive component 7, comprising the following steps:

[0082] S1, setting a working mode in the interactive component 7, and starting the suction device 3, the heating device, and the ultrasonic cleaning device; the interactive component will prompt the working state in each process, so that the operator clearly knows whether the current process is a paint stripping process or a water washing process, and how long the process will be completed, etc., realizing the visualization of the working process, facilitating the operator to reasonably arrange the working rhythm, and avoiding misoperation or time waste due to unclear process progress.

[0083] S2, placing a jig containing a workpiece to the paint stripping station 21 to perform a paint stripping process, and the interactive component 7 prompts the working state. The paint stripping agent steam is sucked by the suction device 3 to the first filter housing 4 for treatment, and after the operation reaches the set time, the interactive component 7 prompts the operator to perform a cleaning process; the working mode can be conveniently set through the interactive component. The operator can quickly adjust the corresponding parameters and operation mode according to the paint stripping and water washing requirements of different workpieces, without the need for complex manual adjustment of each device, so that the operation process is more concise and clear, easy to understand, and improves the operation convenience of the entire paint stripping operation.

[0084] S3, the tool containing the paint removal finished workpiece is placed in the water washing station 21 to perform the water washing process, the paint remover vapor is sucked by the suction device 3 to the second filter assembly 6 for treatment, until the operation reaches the set time, the interactive assembly 7 prompts the operator that the operation is completed, and the operator places the workpiece completing all processes for storage; in the paint removal process and the water washing process, the suction device respectively sucks the paint remover vapor to the first filter housing and the second filter assembly for treatment, so that the paint remover vapor can be avoided from diffusing in the workshop environment at will, the pollution to the air in the workshop is reduced, the air quality in the workshop and the health of the operators are protected. At the same time, after the filtering treatment, the paint remover can be recycled and reused, the consumption of the paint remover is reduced, the utilization rate of resources is improved, and the requirements of environmental protection and sustainable development are met.

[0085] By setting the specific operation steps of the paint removal process and the water washing process and the set time, each workpiece can be processed according to the standard process and time length, the stability of the paint removal and water washing effect is ensured, the quality problems such as incomplete paint removal or unclean water washing caused by random human operation are avoided, the high-quality paint-removed workpieces can be stably output, and the requirements of subsequent production and processing are met.

[0086] S4, repeat steps S2 and S3. Through the design of repeating steps S2 and S3, the paint removal and water washing treatment of multiple workpieces can be continuously and efficiently realized, a stable and efficient production circulation process is formed, the overall production efficiency is greatly improved on the basis of ensuring the processing quality of each workpiece, large-scale and continuous production operation is facilitated, and the applicability and production capacity of the paint removal machine in actual production are improved.

[0087] Further, in some embodiments, each paint removal tank and water washing tank is provided with an independently controllable illuminating lamp above, which facilitates the observation of the paint removal condition by the operator. Further, in some embodiments, the paint removal machine is also provided with an automatic liquid supplementing system, and the paint removal tank is provided with an automatic paint remover supplementing system. With the evaporation of the paint remover, the system can supplement the paint removal tank according to the set paint remover level. The cleaning agent in the water washing tank can be water or a specific cleaning agent, which can be automatically added, discharged or circulated by the system.

[0088] The display screen on the interactive assembly can set the cleaning mode, cleaning intensity and cleaning time length of the ultrasonic cleaning process. When the paint removal process of a batch of workpieces is completed, the alarmer above the corresponding paint removal tank emits a buzzing sound and flashes to prompt that the paint removal operation is completed. When the cleaning process of a batch of workpieces is completed, the alarmer above the water washing tank emits a buzzing sound and flashes to prompt that the cleaning is completed. The heating device is provided with a temperature control system, which can ensure that the paint removal agent in the paint removal tank is heated to the set temperature to achieve the maximum paint removal effect.

[0089] Preferably, in order to improve production efficiency, two paint removal tanks and one water washing tank can be arranged, and the water washing tank is located between the two paint removal tanks, and the two paint removal tanks and the water washing tank are arranged in a straight line.

[0090] In the process of manufacturing inductors and reactors, the coils are usually wound with enameled copper wire or enameled aluminum wire. Therefore, when manufacturing inductors and reactors, the insulating paint on the pins needs to be removed. After the paint is removed, the pin will expose the smooth surface of the enameled wire base material copper or aluminum, and through the subsequent pin tinning process, the inductor product can effectively conduct electricity with other elements, thereby providing good electrical connection and transmission performance. The existing paint removal equipment generally uses manual paint scraping, which is quite time-consuming and labor-intensive. Further, the paint removal machine of the present application is applied in the field of paint removal of the pins of electromagnetic coils, as shown in Figure 10 The jig 10 of the present application is used to place the enameled coil 100, and the jig can allow the vertically placed enameled coil pins to extend into the paint removal liquid in the paint removal tank. The two ends of the jig can abut against the paint removal tank support part or the water washing tank support part for stable placement, and the high-temperature paint remover can effectively remove the insulating paint on the pins.
