Description

Technical Field

[0001] The invention relates to the technical field of casting varnish dipping equipment, and in particular discloses a varnish dipping device for casting processing. Background Art

[0002] Castings refer to metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance. The produced castings need to be treated with varnishing using a varnishing device to achieve the purpose of rust prevention and anti-adhesion, thereby extending the service life of the castings.

[0003] A Chinese patent with announcement number CN213825607U discloses a paint dipping device for small mechanical castings, including a blanking table and a paint dipping tank, one side of the blanking table is fixedly connected to the paint dipping tank, and two brackets are fixedly connected to the two sides of the blanking table. The utility model is provided with an overflow chamber. When too much paint liquid is poured into the paint dipping tank, the paint liquid will flow into the overflow chamber, so that the liquid level in the paint dipping chamber is in the best position for paint dipping, and will not cause excessive paint dipping. After the paint dipping is completed, the utility model places the casting on a placement rack. During the drying process, the excess paint liquid on the surface of the casting will drip onto the blanking table through the placement rack, and then slide back to the paint dipping tank on the blanking table, avoiding the waste of paint liquid caused by volatilization. The utility model is provided with a stirring device. During the paint dipping process, the stirring blades rotate simultaneously, so that the anti-rust paint of the casting is always in a flowing state under the stirring of the blades of the stirring mechanism during the paint dipping process, thereby preventing a large amount of precipitation of the anti-rust paint, making the casting evenly paint-dipped, and greatly improving the paint dipping quality of the casting surface. However, the above-mentioned paint dipping device cannot dry the casting after the paint dipping, which is not conducive to the firm connection between the anti-rust paint and the casting. The above-mentioned paint dipping device is not convenient for placing the casting into the paint dipping tank before paint dipping, and taking it out of the paint dipping tank after paint dipping. In addition, when the cast after the paint dipping is placed on the placement rack for paint dipping, as the anti-rust paint evaporates, the anti-rust paint on the casting is easily adhered to and remains on the placement rack, which leads to uneven paint dipping after the casting is removed from the placement rack, affecting the quality of the casting paint dipping. Therefore, in order to solve the above-mentioned problems, the present invention proposes a paint dipping device for casting processing. Summary of the invention

A transparent observation panel is provided inside the side panel to facilitate observation of the movement and drying conditions of the castings inside the oven so as to adjust the drying rhythm of the oven. Three second grid plates are evenly spaced at the top of the oven to disperse the high-temperature airflows blown out by the first, second and third hot air blowers.

[0010] As a further arrangement of the above scheme, a plurality of first hot air blowers, second hot air blowers and third hot air blowers are respectively arranged longitudinally along the short side of the top surface of the oven above the three second grid plates, so as to control the switching conditions of the three hot air blowers according to the drying conditions of the castings, so as to save resources while ensuring the drying quality. The air outlet ends of the first hot air blowers, the second hot air blowers and the third hot air blowers all pass through the top of the oven. A fourth hot air blower is arranged on one side of the oven, and the air outlet end of the fourth hot air blower is connected to the interior of the trough. A first bracket is connected to the bottom of the fourth hot air blower, which can dry the paint liquid on the surface of the casting from below the casting and make the paint liquid and the casting more firmly connected through high temperature.

[0011] As a further configuration of the above scheme, two slide grooves are symmetrically connected to the bottom of the second bracket, and a plurality of sliders are arranged at equal intervals inside the slide grooves, and the sliders are slidably connected to the slide grooves, and a screw rod is arranged through the inside of the slider, and the slider is threadedly connected to the screw rod, and a second motor is arranged at one end of the screw rod, which can drive the screw rod to rotate through the rotation of the motor and then drive a plurality of sliders to slide synchronously in the slide groove, laying a foundation for the position adjustment of the casting, and a third bracket is arranged on the outside of the second bracket, which can provide stable support for the second bracket and its connecting parts, and two sealing plates are connected to the third bracket and the second bracket at one end close to the drying mechanism, so as to facilitate the removal of the sealing plate from between the third bracket and the second bracket during the assembly of the device, so that the second bracket and the slide groove can pass through the drying mechanism smoothly.

[0012] As a further configuration of the above scheme, a telescopic rod is connected to the bottom of the slider to facilitate adjusting the height of the casting during the paint dipping process, and the telescopic end of the telescopic rod is connected to a second mounting plate, and two connecting plates are provided at both ends of the second mounting plate, and a pin is connected between the two connecting plates at the same end, and a hook is rotatably connected to the outer side of the pin to facilitate hooking the casting to be painted on the hook, so that workers do not directly contact the casting immersed in paint during the paint dipping process.

[0013] As a further configuration of the above scheme, a PLC controller is provided on one side of the third bracket, and the PLC controller is connected to the terminal device via a data cable, so as to facilitate the transmission of the edited operating program in the terminal device to the PLC controller, so as to use the PLC controller to control the operation of relevant components in the device.

[0014] As a further configuration of the above scheme, a plurality of universal brake wheels are connected to the bottom of the servo conveyor belt to facilitate adjustment of the position of the servo conveyor belt and to facilitate workers to clean and maintain the paint dipping mechanism.

[0015] The second motor in the present invention is a servo motor.

[0016] The paint dipping device for casting processing, during use, uses a PLC controller to start the first motor, so that the first motor drives the stirring rod to rotate, stirs the paint liquid in the paint storage box, and conveys the casting to be dipped in paint to the bottom of the conveying mechanism through the servo conveyor belt. The worker hooks the casting on the hook below the telescopic rod closest to the drying mechanism, and uses the PLC controller to start the second motor, so that the second motor drives the screw rod to rotate, and then drives the slider to slide in the slide slot, and moves the telescopic rod on the servo conveyor belt together with the casting hooked on the hook below the telescopic rod to the top of the paint storage box, and then turns off the second motor. At this time, another telescopic rod connected to an empty hook is synchronously moved to the top of the servo conveyor belt, and the telescopic rod above the paint storage box is controlled to extend, so that the casting is completely immersed in the paint liquid in the paint storage box. After a period of time, the telescopic rod is controlled to contract to pull the casting out of the paint liquid. The second motor is then turned on and off to move the paint-dipped castings to the top of the drain plate and then closed. The paint on the castings drips onto the drain plate and then gathers at the paint return port and flows back to the paint storage box through the hose. After a period of time, the second motor is automatically turned on to drive the multiple sliders to move synchronously again to move the paint-dipped castings to the oven for drying. The second motor is then turned on for a period of time and then turned off until all the paint-dipped castings under the sliders in the two slides are sent out from the end of the oven away from the paint dipping mechanism. The castings that have been dipped and dried are removed from the hooks in turn and placed on the corresponding storage device. The second motor is controlled to rotate to move all the sliders in a single slide and the telescopic rods connected thereto to the end of the second bracket away from the oven. The above operation is then repeated to allow the remaining castings to be dipped in paint.

[0017] The present invention has the following beneficial effects in practical application: The device has the functions of painting, draining and drying castings to ensure the quality of painting. The use of multiple universal brake wheels under the servo conveyor belt in the device makes it easy to adjust and fix the position of the servo conveyor belt so that the castings to be painted can be conveyed to the bottom of the second bracket, and the distance between the castings and the ground can be increased, so that workers can hook the castings without bending over excessively. When maintenance of the painting mechanism is required, one side of the painting mechanism driven by the servo conveyor can be moved away by rotating the universal brake wheel so that workers can carry out maintenance operations on the painting mechanism.

[0018] The use of the first grid in the paint dipping mechanism can slow down the fluctuation of the paint liquid on the side of the first grid away from the motor, thereby avoiding the impact of excessive fluctuation of the paint liquid on the quality of the casting dipping. The use of multiple first hot air blowers, second hot air blowers and third hot air blowers in the drying mechanism makes it convenient for workers to adjust the switching conditions of the above three hot air blowers according to the drying conditions of the castings, thereby ensuring the drying quality of the castings and saving resources. The use of the fourth hot air blower can dry the bottom of the casting and improve the drying efficiency of the castings.

[0019] The combination of two sets of slide grooves, sliders, screw rods and the second motor in the conveying mechanism makes it easy to simultaneously drive the movement of multiple sliders connected to the outside of the screw rod through the same second motor, thereby realizing the synchronous adjustment of the positions of multiple telescopic rods and their connecting parts and castings, and then changing the positions of castings hooked under different telescopic rods, thereby changing the paint dipping step of the castings, ensuring that there are castings in the paint storage box, draining table and drying oven at the same time, so as to ensure the continuity of the casting dipping operation and improve the efficiency of casting dipping.

[0033] like Figure 1 and Fig. 9 As shown, a PLC controller 5 is provided on one side of the third bracket 32, and the PLC controller 5 is connected to the terminal device via a data cable, so as to facilitate the transmission of the edited operating program in the terminal device to the PLC controller 5, so as to use the PLC controller 5 to control the operation of relevant components in the device.

[0034] like Figure 1 As shown, a plurality of universal brake wheels 41 are connected to the bottom of the servo conveyor belt 4 to facilitate adjustment of the position of the servo conveyor belt 4 and to facilitate workers to clean and maintain the paint dipping mechanism 1.

[0035] The paint dipping device for casting processing disclosed in the present embodiment, after a sufficient amount of paint liquid is injected into the paint storage box 11 before use, uses the PLC controller 5 to start the first motor 14, so that the first motor 14 drives the stirring rod 15 to rotate, and stirs the paint liquid in the paint storage box 11 on one side of the first grid plate 16, so that the paint liquid flows on both sides of the first grid plate 16, speeding up the speed of breaking up the precipitation in the paint liquid and avoiding the precipitation of the paint liquid, and uses the PLC controller 5 to start the fourth hot air blower 28, multiple first hot air blowers 24, the second hot air blower 25 and the third hot air blower 26 in sequence to preheat the interior of the oven 21.

[0036] The PLC controller 5 is used to control the opening and closing of the servo conveyor belt 4 so that the servo conveyor belt 4 conveys the casting to be dipped in paint to the bottom of the conveying mechanism 3. The sliders 34 connected to the outside of the same screw rod 35, three of which are taken as an example here, are named A slider 34, B slider 34 and C slider 34 according to the distance from the second motor 36, and the sliders 34 outside another screw rod 35 are named a slider 34, b slider 34 and c slider 34 according to the distance from the other second motor 36. The worker picks up the casting on the servo conveyor belt 4 and hooks them on the hooks 39 connected below the telescopic rod 37 below the A slider 34 and the a slider 34, and uses the PLC controller 5 to start the two second motors 36 at the same time, so that the two second motors 36 drive the screw rods respectively. 35 rotates, thereby driving the slider 34 connected to the outside of the paint to slide in the slide groove 33, and the A slider 34 and the a slider 34 together with the telescopic rods 37 and the castings on the hooks 39 below them are moved to the top of the paint storage box 11, and then the second motor 36 is turned off. At this time, the telescopic rods 37 connected to the bottom of the B slider 34 and the b slider 34 are synchronously moved to the top of the servo conveyor belt 4, and the workers hook the castings on the hooks 39 below the B slider 34 and the b slider 34 respectively, and use the PLC controller 5 to control the extension of the telescopic rods 37 under the A slider 34 and the a slider 34. After the castings are completely immersed in the paint liquid in the paint storage box 11 for a period of time, the PLC controller 5 is used to control the contraction of the telescopic rods 37 under the A slider 34 and the a slider 34 to pull the castings out of the paint liquid.

[0037] At this time, the second motor 36 is started again, and drives the multiple sliders 34 to move synchronously in the slide rails again, and moves the A slider 34 and the a slider 34 to the top of the drain plate 125. At this time, the B slider 34 and the b slider 34 drive the telescopic rods 37 below them and the castings hooked on the hooks 39 to move to the top of the paint storage box 11, and the C slider 34 and the c slider 34 move to the top of the servo telescopic rod 37.
