[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0039] like Figure 1-3 As shown, the utility model provides an automatic paint stripping device for stripping defective products, comprising:

[0040] The tank body 100 has a receiving space that can be opened or closed;

[0041] A plurality of spray pipes 110 are provided in the accommodation space;

[0042] The hanger 200 is provided with a rotating shaft 210 at the bottom. The rotating shaft 210 is driven by a motor 211 to rotate and drive the hanger 200 to rotate. The hanger 200 is placed in the accommodating space and located between multiple spray pipes 110. As the spray pipes 110 spray the agent, the hanger 200 continues to rotate to increase the contact area between the product and the agent, thereby improving the paint stripping effect.

[0043] The automatic paint stripping device provided in this embodiment has at least the following advantages:

[0044] 1. Improve paint stripping efficiency: The rotation of the hanger increases the contact area between the product and the agent, allowing the paint stripping agent to cover the product surface more evenly, thereby improving the efficiency and quality of paint stripping;

[0045] 2. Reduce the proportion of paint peeling defects: The combination of the spray system and the rotation of the hanger can effectively remove the dead paint on the product surface and reduce the proportion of paint peeling defects;

[0046] 3. Reduced drug consumption: The combination of the spray system and the rotation of the hanger 200 improves the utilization rate of the drug and reduces drug consumption;

[0047] 4. Easy to operate and maintain: The device is movable and detachable. It can be removed by forklift before and after paint stripping, which is convenient and easy to operate. At the same time, the closed design also helps to simplify daily cleaning and maintenance work.

[0048] 5. Reduce the cost of paint residue treatment: the closed design and effective spray system reduce the generation of paint residue and reduce the cost of subsequent paint residue treatment;

[0049] Preferably, the hanger 200 includes a plurality of product mounting plates 220, and a connecting rod 230 is provided on the side of the product mounting plates 220. The product mounting plates 220 are spaced apart in the vertical direction and connected by the connecting rod 230, thereby forming a layered structure for hanging products.

[0050] Furthermore, a connecting sleeve 240 is provided on the side of the product mounting plate 220, and the connecting rod 230 is inserted into the connecting sleeve 240 and fastened by a fastener 250, so that the multiple product mounting plates 220 form a layered structure with adjustable height;

[0051] Through the height-adjustable layered structure design, the distance between the product mounting plates 220 can be adjusted according to products of different lengths, thereby adapting to products of various specifications and improving the versatility of the device.

[0052] In addition, a number of positioning grooves 221 are evenly distributed on the product mounting plate 220 at the bottom, and a number of through holes 222 are evenly distributed on other product mounting plates 220. The products pass through the through holes 222 of each product mounting plate 220 and rest on the positioning grooves 221, thereby ensuring that the products will not shake or fall off during the paint stripping process, ensuring the smooth progress of the paint stripping process, and maintaining a reasonable distance between adjacent products to ensure that the agent can fully contact the surface of each product, thereby improving the paint stripping efficiency.

[0053] Preferably, the hanger 200 further includes a bottom plate 260, a plurality of vertically upward fixing rods 270 are provided on the side of the bottom plate 260, and a placement space is formed on the top surface of the bottom plate 260, and a layered structure composed of multiple product mounting plates 220 is located in the placement space;

[0054] Among them, the rotating shaft 210 is located at the bottom center of the base plate 260, and the motor 211 drives the rotating shaft 210 to rotate through the chain 212, and drives the base plate 260 to rotate. Therefore, as the base plate 260 rotates, the layered structure used to hang the product can be driven to rotate, thereby achieving the purpose of increasing the contact area between the product and the medicine.

[0055] Preferably, the tank body 100 is provided with an exhaust system, through which the gas generated by the reaction in the tank body 100 is extracted outward through the exhaust duct 120 and sent to the external acid mist tower for treatment, thereby effectively controlling the emission of harmful gases, avoiding pollution to the surrounding environment, and improving environmental protection performance.

[0056] Preferably, a rolling shutter door 130 is provided on the front of the trough body 100. When the rolling shutter door 130 is lowered, a closed accommodation space is formed in the trough body 100, which reduces the volatilization of the paint stripping agent and its impact on the environment and improves the safety of the production process; when the rolling shutter door 130 is raised, the hanger 200 can be moved out from the trough body 100 to facilitate loading and unloading and processing of the product.

[0057] Preferably, a liquid storage tank 140 is further included, which is located outside the tank body 100 and communicated with the inside of the tank body 100 , and the sprayed medicine in the tank body 100 flows into the liquid storage tank 140 .

[0058] Among them, the liquid storage tank 140 and the spray pipe 110 are connected by pipelines and a circulation pump 150. The circulation pump 150 is used to transport the medicine in the liquid storage tank 140 to the spray pipe 110 for reuse, which greatly reduces the consumption of the medicine, improves the utilization rate of the medicine, and reduces operating costs.
