Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coating removal technology, and specifically relates to a continuous line for coating product removal and rework. Background Technology
[0002] Existing coated products may require rework and decoating processes due to various needs such as usage requirements and other process requirements. This involves cleaning the coated product to peel off the coating, also known as the product coating removal and rework step. Specifically, multiple cleaning tanks are set up, and different cleaning solutions are placed in different tanks and heated according to the cleaning process. The product requiring decoating is then passed through each tank sequentially to achieve the desired decoating removal.
[0003] Existing methods for removing and repairing coated products typically have the following two problems:
[0004] 1. In order to achieve better heating effect in the cleaning tank, the cleaning fluid is usually heated to 100℃. However, this is energy-intensive, and the high temperature will also affect the safety of the processing.
[0005] 2. Existing cleaning tanks are all designed to be open, meaning the opening is wide. Since the cleaning fluid is heated, the open structure of the cleaning tank will cause the cleaning fluid to evaporate and a large amount of heat to dissipate, thereby increasing the overall energy consumption of the device.
[0006] Based on the above problems, there is an urgent need for a device that can solve these problems. Utility Model Content
[0007] To address the aforementioned problems, the primary objective of this invention is to provide a continuous line for the removal and rework of coated products, which reduces energy consumption and provides a good removal effect.
[0008] To achieve the above objectives, the technical solution of this utility model is as follows.
[0009] A continuous line for the removal and rework of coated products, comprising:
[0010] The machine frame has a processing channel.
[0011] Multiple cleaning tanks are arranged sequentially in the processing channel, and at least one cleaning tank is equipped with a heating mechanism for heating the cleaning fluid.
[0012] The transfer mechanism is movably connected to the frame to transfer the products to be cleaned between different cleaning tanks;
[0013] The continuous line also includes at least one cleaning tank equipped with an ultrasonic mechanism for generating and transmitting ultrasonic waves into the cleaning tank. Each cleaning tank has an opening, and at least one cleaning tank opening is covered with a sealing cap. In practice, it is preferable to place the product to be cleaned on a cleaning basket, and a transfer mechanism moves the cleaning basket between different cleaning tanks, thereby enabling the product to be cleaned to move between different cleaning tanks.
[0014] In this invention, by setting a heating mechanism and an ultrasonic mechanism on the cleaning tank, ultrasonic waves can be generated simultaneously with heating. The combined effect of heating and ultrasonic waves can improve the cleaning effect without heating the cleaning solution to boiling. In addition, a sealing cap is set on the opening of the cleaning tank, which can reduce the evaporation and heat loss of the cleaning solution after it is heated, thereby reducing energy consumption and ensuring the temperature stability inside the cleaning tank to a certain extent, thus improving the cleaning and stripping effect.
[0015] Furthermore, the cleaning tank includes a high-manganese tank, a water trough, a first spray tank, a dewaxing tank, a second spray tank, and a rinsing tank arranged in sequence. The high-manganese tank, the dewaxing tank, and the rinsing tank are all equipped with heating and ultrasonic mechanisms. The high-manganese tank is used to hold potassium permanganate, the water trough is used to hold clean water or tap water or other specialized cleaning solutions, the first and second spray tanks are used to spray clean water or tap water, the dewaxing tank is used to hold dewaxing liquid, and the rinsing tank is used to hold clean water or tap water.
[0016] Furthermore, there are twelve high-manganese tanks, three water-passing tanks, one first spray tank, one dewaxing tank, one second spray tank, and two rinsing tanks. The combination of these tanks achieves good stripping and cleaning effects.
[0017] Furthermore, the continuous line also includes an inlet pipe, a liquid pump, a connecting pipe, and an outlet pipe. The inlet pipe is connected to the last water tank for water supply. Each adjacent water tank is connected via a connecting pipe. The outlet pipe is connected to the first water tank. Multiple liquid pumps are used to sequentially pump the liquid from the last water tank to the previous water tank until the first water tank. This structure allows for full utilization of the liquid in the water tanks. Because the contamination level gradually decreases from the first water tank to the last, when the liquid in the first water tank is no longer usable, it is discharged from the outlet pipe and then pumped from the next water tank to the previous water tank via the connecting pipe. This cyclical arrangement ensures continuous operation while guaranteeing full utilization of the liquid in each water tank.
[0018] Furthermore, the heating mechanism includes a heating plate, and the ultrasonic mechanism includes an ultrasonic transducer, with both the heating plate and the ultrasonic transducer mounted on the outer surfaces of the high-manganese tank, the dewaxing tank, and the rinsing tank. Preferably, the heating plate is fixed to the front and rear outer surfaces of the high-manganese tank, the dewaxing tank, and the rinsing tank; the ultrasonic transducer is fixed to the left and right outer surfaces of the high-manganese tank, the dewaxing tank, and the rinsing tank. Mounting the heating plate and the ultrasonic transducer on the outer surfaces of the high-manganese tank, the dewaxing tank, and the rinsing tank prevents corrosion from the liquid inside the tank, improves the service life of the heating plate and the ultrasonic transducer, and allows for more uniform heat and ultrasonic wave conduction through the tank walls.
[0019] Furthermore, the material transfer mechanism includes a gantry robotic arm.
[0020] This utility model also provides a method for repairing coated products after removal, including:
[0021] Feeding: The product to be cleaned is fed into the high manganese tank through a transfer mechanism;
[0022] Stripping: The product to be cleaned is passed through each high-manganese tank in sequence and left to stand in each high-manganese tank for a specified time;
[0023] Cleaning: The products to be cleaned are sequentially fed from the last high-manganese tank into each water tank and left to stand in each water tank for a specified time.
[0024] One-time spraying: The product to be cleaned is sent from the last water tank into the first spray tank, and clean water is sprayed in the first spray tank for a specified time;
[0025] Dewaxing: The product to be cleaned is sent from the first spray tank into the dewaxing tank and left to stand in the dewaxing tank for a specified time;
[0026] Secondary spraying: The product to be cleaned is sent from the dewaxing tank into the second spraying tank, and clean water is sprayed in the second spraying tank for a specified time;
[0027] Rinsing: The products to be cleaned are sequentially fed from the second spray tank into each rinsing tank and left to stand in the rinsing tank for a specified time.
[0028] The specified time is determined based on the specific products to be cleaned.
[0029] Furthermore, the rinsing step is followed by a slow-pull step: the product to be cleaned is pulled out of the last rinsing tank at a speed of 20mm / s-30mm / s using a transfer mechanism. This slow-pull step ensures that the product is pulled out dry due to the water temperature and surface tension, preventing water from being brought up with it, thus ultimately guaranteeing the cleanliness of the product.
[0030] Furthermore, the temperatures of the high-manganese tank, dewaxing tank, and rinsing tank are maintained between 25℃ and 65℃. To better adapt to various scenarios, a maximum temperature setting of 85℃ is sufficient to meet the needs of various scenarios, without the need to set it to 100℃.
[0031] Furthermore, the ultrasonic mechanism of the high manganese tank, dewaxing tank, and rinsing tank has a frequency of 28KHz and a power of 6000W.
[0032] The beneficial effects of this utility model are as follows: by setting a heating mechanism and an ultrasonic mechanism on the cleaning tank, ultrasonic waves can be generated while heating. The combined effect of heating and ultrasonic waves can improve the cleaning effect without heating the cleaning solution to boiling. In addition, the top cover with a sealing cap on the opening of the cleaning tank can reduce the evaporation and heat loss of the cleaning solution after it is heated, thereby reducing energy consumption and ensuring the temperature stability inside the cleaning tank to a certain extent, thus improving the cleaning and stripping effect.

[0052] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0053] See Figure 1-9 This embodiment provides a continuous line for the removal and rework of coated products, including:
[0054] The machine frame 1 is provided with a processing channel 11, a loading position 12 and a unloading position 13.
[0055] Multiple cleaning tanks 2 are arranged sequentially in the processing channel 11, and at least one cleaning tank 2 is equipped with a heating mechanism 3 for heating the cleaning liquid;
[0056] The transfer mechanism 4 is movably connected to the frame 1 to transfer the products to be cleaned in different cleaning tanks 2;
[0057] The continuous line also includes at least one cleaning tank 2 equipped with an ultrasonic mechanism 5 for generating and transmitting ultrasonic waves into the cleaning tank 2. Each cleaning tank 2 has an opening, and at least one cleaning tank 2 has a sealing cover 6 covering the opening. In actual operation, the product to be cleaned is placed on a cleaning basket, and the transfer mechanism 4 moves the cleaning basket between different cleaning tanks 2, thereby enabling the product to be cleaned to move between different cleaning tanks 2.
[0058] In this invention, by setting a heating mechanism 3 and an ultrasonic mechanism 5 on the cleaning tank 2, ultrasonic waves can be generated while heating. The combined effect of heating and ultrasonic waves can improve the cleaning effect without heating the cleaning liquid to boiling. In addition, a sealing cap 6 is set on the opening of the cleaning tank 2, which can reduce the evaporation and heat loss of the cleaning liquid after it is heated, thereby reducing energy consumption and ensuring the temperature stability inside the cleaning tank 2 to a certain extent, thus improving the cleaning and stripping effect.
[0059] In this embodiment, the cleaning tank 2 includes a high-manganese tank 21, a water tank 22, a first spray tank 23, a dewaxing tank 24, a second spray tank 25, and a rinsing tank 26 arranged in sequence. The high-manganese tank 21, the dewaxing tank 24, and the rinsing tank 26 are all equipped with a heating mechanism 3 and an ultrasonic mechanism 5. The high-manganese tank 21 is used to hold potassium permanganate, the water tank 22 is used to hold clean water or tap water or other special cleaning solutions, the first spray tank 23 and the second spray tank 25 are used to spray clean water or tap water, the dewaxing tank 24 is used to hold dewaxing liquid, and the rinsing tank 26 is used to hold clean water or tap water.
[0060] In this embodiment, there are twelve high-manganese plating tanks 21, three water rinsing tanks 22, one first spray tank 23, one dewaxing tank 24, one second spray tank 25, and two rinsing tanks 26. The combination of these tanks can achieve a better stripping and cleaning effect.
[0061] In this embodiment, the continuous line also includes an inlet pipe (not shown), a liquid pump 7, a connecting pipe 8, and an outlet pipe (not shown). The inlet pipe is connected to the last water tank 22 for water supply. Each adjacent water tank 22 is connected via the connecting pipe 8. The outlet pipe is connected to the first water tank 22. Multiple liquid pumps are used to sequentially pump the liquid from the last water tank 22 to the previous water tank 22 until the first water tank 22. This structure allows for full utilization of the liquid in the water tanks 22. Because the contamination level gradually decreases from the first water tank 22 to the last water tank 22, when the liquid in the first water tank 22 is no longer usable, the liquid is discharged from the outlet pipe and then pumped from the next water tank 22 to the previous water tank 22 via the connecting pipe. This cyclical arrangement ensures continuous operation while guaranteeing full utilization of the liquid in each water tank 22.
[0062] In this embodiment, both the inner surfaces of the first spray tank 23 and the second spray tank 25 are provided with mounting grooves 9, and spray heads 10 are installed in the mounting grooves 9, with the height of the spray heads 10 being lower than the depth of the mounting grooves 9. This structural arrangement allows for the concealed installation of the spray heads 10, preventing them from colliding with the product to be cleaned and maintaining a certain distance from it, thereby improving the cleaning effect.
[0063] In this embodiment, the heating mechanism 3 includes a heating plate 31, and the ultrasonic mechanism 5 includes an ultrasonic transducer 51. Both the heating plate 31 and the ultrasonic transducer 51 are installed on the outer surfaces of the high-manganese tank 21, the dewaxing tank 24, and the rinsing tank 26. The heating plate 31 is fixed to the front and rear outer surfaces of the high-manganese tank 21, the dewaxing tank 24, and the rinsing tank 26; the ultrasonic transducer 51 is fixed to the left and right outer surfaces of the high-manganese tank 21, the dewaxing tank 24, and the rinsing tank 26. Installing the heating plate 31 and the ultrasonic transducer 51 on the outer surfaces of the high-manganese tank 21, the dewaxing tank 24, and the rinsing tank 26 prevents corrosion from the liquid inside the tanks, improves the service life of the heating plate 31 and the ultrasonic transducer 51, and also allows for more uniform heat and ultrasonic wave conduction through the tank walls.

[0071] Secondary spraying: The product to be cleaned is sent from the dewaxing tank 24 into the second spraying tank 25, and clean water is sprayed in the second spraying tank 25 for a specified time.
[0072] Rinsing: The products to be cleaned are sequentially fed from the second spray tank 25 into each rinsing tank 26 and left to stand in the rinsing tank 26 for a specified time.
[0073] The specified time is determined based on the specific products to be cleaned.
[0074] In this embodiment, a slow-pull step is included after the rinsing step: the product to be cleaned is pulled out of the last rinsing tank 26 at a speed of 20mm / s-30mm / s by the transfer mechanism 4. Through the above-mentioned slow-pull step, the product to be cleaned is pulled out in a dry state under the action of water temperature and water tension, without bringing water up with it, thereby ultimately ensuring the cleanliness of the product to be cleaned.
[0075] In this embodiment, the temperatures of the high-manganese tank 21, the dewaxing tank 24, and the rinsing tank 26 are maintained between 25°C and 65°C. To better adapt to various scenarios, a maximum temperature setting of 85°C is sufficient to meet the needs of various scenarios, and there is no need to set it to 100°C.
