Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a device for drying iron parts after impregnation with adhesive. Background Technology

[0002] With the rapid development of automotive parts manufacturing technology, manufacturing equipment and auxiliary devices are becoming increasingly efficient and sophisticated. For example, most automotive parts such as engine blocks, cylinder heads, reducers, axle housings, clutch plates, cylindrical gear housings, and balance shaft supports have achieved automated processing.

[0003] Key components in industries such as automobiles, tractors, rail transportation, and CNC machine tools, including engine blocks, cylinder heads, reducers, axle housings, clutch plates, cylindrical gear housings, and balance shaft supports, are generally made of cast iron. Cast iron, due to its high strength, excellent thermal conductivity and resistance to thermal fatigue, and good machinability, has become an irreplaceable metallic material widely used in the production of components in mechanical industries with complex stresses and high requirements for strength, toughness, and wear resistance. However, the complex structure, multifaceted and porous nature of cast iron mechanical parts, the complex coating process, and the stringent performance requirements of coating manufacturers necessitate that water-based anti-corrosion coatings not only address production safety, environmental protection, and health issues during construction, but also meet or exceed the technical specifications of similar solvent-based anti-corrosion coatings. Furthermore, water-based anti-corrosion coatings must have strong application adaptability and meet the process specifications of existing solvent-based anti-corrosion coating equipment and construction requirements, posing a significant challenge to the "oil-to-water" coating technology. The ideal conventional spraying process is to use an automated dip coating line. Currently, China has established a complete production line for standardized dip coating processes of water-based industrial anti-corrosion coatings, particularly for cast iron machinery parts. This production line includes shot blasting, dip coating, and drying of the iron parts. Operators hang the workpieces on a suspended chain in the loading area. The chain operates in a step-by-step manner, carrying the iron parts along the production line sequentially through shot blasting, dust removal, preheating, base coating, first coating application, hot air drying, second coating application, base coating curing, cold air drying, top coating application, first coating application, hot air drying, second coating application, top coating curing, cold air drying, and finally, unloading. However, existing dip coating methods are inconvenient; the adhesive cannot be effectively maintained at the required temperature, resulting in low dip coating efficiency and consequently, low production line efficiency. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a glue-drying device for iron parts that is convenient to use, improves glue-drying efficiency, and has a good glue-drying effect.

[0005] To solve this technical problem, the present invention adopts the following solution: a metal parts dipping and drying device, comprising a controller, a suspension chain on a production line, multiple hangers on the suspension chain, a dipping mechanism, a scraping mechanism, and a drying mechanism. The suspension chain transports the metal parts on each hanger to the dipping mechanism for dipping and then to the scraping mechanism for scraping. After scraping, the suspension chain transports the metal parts on each hanger to the drying mechanism for drying and then to the next process on the production line. The dipping mechanism includes a frame, a glue supply tank, a dipping tank, a first liquid pump, a second liquid pump, and a lifting mechanism. The glue supply tank is located at the lower part of the frame, and the dipping tank is vertically movable via the lifting mechanism. The upper part of the frame and the dip tank are located above the glue supply tank. The first liquid pump is located on the frame and its inlet is connected to the glue supply tank. The outlet of the first liquid pump is connected to the dip tank to pump the glue solution from the glue supply tank into the dip tank. The second liquid pump is located on the frame and its inlet is connected to the dip tank. The outlet of the second liquid pump is connected to the glue supply tank to pump the glue solution from the dip tank into the glue supply tank. The upper part of the dip tank is provided with an overflow port, which is connected to the glue supply tank through a pipe. The first liquid pump, the second liquid pump and the lifting mechanism are all connected and controlled by a controller.

[0006] In a further improvement, the impregnation mechanism also includes a first stirring mechanism and a second stirring mechanism, which are respectively located at the bottom center of the glue supply tank and the impregnation tank.

[0007] In a further improvement, the dipping mechanism also includes a first pusher mechanism and a second pusher mechanism. The first pusher mechanism and the second pusher mechanism are respectively located at the bottom of the glue supply tank and the dipping tank, and horizontally push the glue liquid back and forth. The middle part of the pusher plate of the first pusher mechanism and the second pusher mechanism is provided with a groove to avoid the stirring shaft of the first stirring mechanism or the second stirring mechanism.

[0008] In a further improvement, the impregnation mechanism also includes a water cooling mechanism and two temperature sensors. The water cooling mechanism includes a coil and a chiller connected to the coil. The coil is placed in the glue supply tank to cool the glue solution. The two temperature sensors are respectively placed in the glue supply tank and the impregnation tank to detect the temperature of the glue solution in the glue supply tank and the impregnation tank and send the data to the controller. The controller is connected to and controls the water cooling mechanism.

[0009] As a further improvement, both the first and second pumps are diaphragm pumps.

[0010] In a further improvement, the glue-scraping mechanism includes a second lifting mechanism, a support plate, and a glue-scraping sponge. The glue-scraping sponge is located on the upper surface of the support plate. The support plate is vertically raised and lowered below the suspension chain via the second lifting mechanism, allowing the glue-scraping sponge to scrape the glue off the bottom of the iron parts on each hanger transported by the suspension chain.

[0011] As a further improvement, the bottom of the impregnation tank is provided with a cleaning discharge port.

[0012] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: By installing the dipping tank, which can be raised and lowered on the upper part of the frame via a lifting mechanism, the iron parts on the various hangers conveyed by the suspension chain are dipped in the rising dipping tank. This reduces the volume of the dipping tank, saves adhesive, and allows for rapid completion. The dipping process is convenient, efficient, and yields good results. The controller sets the pumping volume of the first pump to be greater than that of the second pump. The first pump continuously delivers adhesive into the dipping tank, and the excess adhesive overflows through the overflow port back to the supply tank. Simultaneously, the second pump draws adhesive from the dipping tank to the supply tank, allowing the adhesive to circulate between the supply tank and the dipping tank. This prevents the adhesive in the dipping tank from heating up due to the temperature of the iron parts, ensuring a smooth and efficient dipping process. The first and second stirring mechanisms, as well as the first and second pusher mechanisms, are designed to prevent sedimentation of the adhesive, ensuring uniformity and improving the impregnation effect. The water-cooling mechanism and two temperature sensors maintain the adhesive temperature within the effective impregnation range. When the temperature reaches a preset threshold, the controller activates the water-cooling mechanism to cool the adhesive, allowing the low-temperature adhesive from the electrically supplied adhesive tank to enter the impregnation tank for neutralization and further cooling, thus maintaining the adhesive within the effective temperature range and improving the impregnation effect on the iron parts. The scraping mechanism includes a second lifting mechanism, allowing for appropriate scraping of iron parts of different sizes and lengths by adjusting the height of the support plate, making it more convenient to use and suitable for widespread application.

For example, the drying mechanism has been disclosed in Chinese patent document CN201711098708.5, "An Impregnation Process of Water-based Industrial Anti-corrosion Coating for Cast Iron Mechanical Parts". Therefore, the following embodiments will not describe them in detail.

[0015] refer to Figure 1The preferred iron part dipping and drying device of this utility model includes a controller, a suspension chain 1 of the production line, multiple hangers 2 on the suspension chain 1, a dipping mechanism, a scraping mechanism 4, and a drying mechanism. The suspension chain 1 transports iron parts 5 from each hanger 2 to the dipping mechanism for dipping and then to the scraping mechanism 4 for scraping. The scraping mechanism 4 includes a second lifting mechanism 41, a support plate 42, and a scraping sponge 43. The second lifting mechanism 41 is a cylinder. The scraping sponge 43 is disposed on the surface of the support plate 42. The support plate 2 is vertically raised and lowered below the suspension chain 1 via the second lifting mechanism 41, so that the scraping sponge 43 scrapes the bottom of the iron parts 5 on each hanger 2 transported by the suspension chain 1. After the glue application is completed, the overhead chain 1 transports the iron parts 5 on each hanger 2 to the drying mechanism for drying, and then sends them to the next process on the production line. The glue dipping mechanism includes a frame 31, a glue supply tank 32, a glue dipping tank 33, a first liquid pump 34, a second liquid pump 35, a lifting mechanism 36, a water cooling mechanism 37, two temperature sensors 38, a first stirring mechanism 39, and a second stirring mechanism 310. The first liquid pump 34 and the second liquid pump 35 are both diaphragm pumps. The lifting mechanism 36 consists of two cylinders located on both sides of the glue supply tank 32, with the output ends of the two cylinders connected to both sides of the glue dipping tank 33. The glue supply tank 32 is located at the lower part of the frame 31, and the glue dipping tank 33 can be moved up and down via the lifting mechanism 36. The lifting mechanism is located on the upper part of the frame 31, and the dipping tank 33 is located above the glue supply tank 32. The first stirring mechanism 39 and the second stirring mechanism 310 are respectively located at the bottom center of the glue supply tank 32 and the dipping tank 33. The bottom of the dipping tank 33 is provided with a cleaning and discharge port 331. The first liquid pump 34 is located on the frame 31, and the inlet of the first liquid pump 34 is connected to the inside of the glue supply tank 32. The outlet of the first liquid pump 34 is connected to the dipping tank 33 to pump the glue liquid in the glue supply tank 32 into the dipping tank 33. The second liquid pump 35 is located on the frame 31, and the inlet of the second liquid pump 35 is connected to the inside of the dipping tank 33. The outlet of the second liquid pump 35 is connected to the glue supply tank 32. The glue solution in the dipping tank 33 is pumped to the glue supply tank 32 through the connection of the tank 32. The dipping tank 33 is provided with an overflow port 332 at the top. The overflow port 332 is connected to the glue supply tank 32 through a pipe. The water cooling mechanism 37 includes a coil and a chiller connected to the coil. The coil is located in the glue supply tank 32 to cool the glue solution. Two temperature sensors 38 are respectively located in the glue supply tank 32 and the dipping tank 33 to detect the temperature of the glue solution in the glue supply tank 32 and the dipping tank 33 and send it to the controller. The first liquid pump 34, the second liquid pump 35, the lifting mechanism 36, the chiller of the water cooling mechanism 37, the first stirring mechanism 39 and the second stirring mechanism 310 are all connected and controlled by the controller.

[0016] In the above embodiments, the dipping mechanism can also be supplemented with a first pusher mechanism and a second pusher mechanism. The first and second pusher mechanisms are respectively positioned at the bottom of the glue supply tank and the dipping tank, horizontally pushing the glue back and forth. The pusher plates of the first and second pusher mechanisms have grooves in the middle to avoid obstructing the stirring shaft of the first or second stirring mechanism, preventing sedimentation at the bottom of the glue supply tank and the dipping tank. Both the lifting mechanism and the second lifting mechanism can be hydraulic cylinders or screw motors. Alternatively, the lifting mechanism can use only one cylinder, hydraulic cylinder, or screw motor to drive the lifting of the dipping tank. Setting two symmetrical mechanisms to drive the lifting simultaneously makes the lifting of the dipping tank more stable. Furthermore, to facilitate smooth lifting of the dipping tank, redundant configurations can be made for the outlet pipe connected to the first liquid pump and the inlet pipe connected to the second liquid pump, ensuring that the outlet and inlet pipes remain within the dipping tank even when it reaches its highest position.
