[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Please see Figures 1-8 This embodiment provides a sheet metal part pretreatment spraying and degreasing device, including a degreasing machine body 1, an adjustment plate 2 is provided in the inner cavity of the degreasing machine body 1, and the adjustment plate 2 is wavy. The surface of the adjustment plate 2 is provided with grooves 3. A spraying device is provided above the inner cavity of the degreasing machine body 1. A fixing block 10 is fixedly connected to the bottom of the inner cavity of the degreasing machine body 1. The surface of the fixing block 10 is provided with an immersion tank 11.
[0027] In this embodiment, the wave-shaped structure of the adjustment plate 2 causes the sheet metal part to be pushed and squeezed towards the adjustment plate 2 under the conveyor belt 14, causing one end of the sheet metal part to be raised and the part to be gripped to be suspended in the groove 3. At this time, the hook on the surface of the first conveyor belt 12 can hook the sheet metal part during normal conveying and then convey it to the spraying device for spraying and degreasing. The arc-shaped structure on the surface of the wave-shaped adjustment plate 2 can reduce the friction on the sheet metal part, thereby reducing the risk of wear or deformation of the sheet metal part.
[0028] In this embodiment, a hollow shaft 4 and a support rod 21 are rotatably connected to the inner cavity of the degreasing machine body 1. A groove 5 is provided on the surface of the adjustment plate 2. The support rod 21 is rotatably connected to the adjustment plate 2 through the groove 5. A flip plate 22 is fixedly connected to the surface of the hollow shaft 4. The flip plate 22 is located below the adjustment plate 2 and squeezes the adjustment plate 2 by rotation.
[0029] In this embodiment, the rotation of the hollow shaft 4 causes the flipping plate 22 to press the adjustment plate 2, causing the adjustment plate 2 to rotate around the support rod 21. As a result, the bottom of the adjustment plate 2 is lifted upward, allowing the feeding conveyor belt 14 to transport the sheet metal parts to the area below the adjustment plate 2 for immersion degreasing. By controlling the rotation of the adjustment plate 2, different sheet metal parts can be transported to the spray degreasing area or the immersion degreasing area. The two degreasing methods can be switched easily, increasing the scope of use of the equipment, saving floor space, and automating the internal degreasing process, thus saving labor costs.
[0030] In this embodiment, the control rod 6 slides in the inner cavity of the locking slot 7 via the locking block 8 to move closer to or further away from the degreasing machine body 1, and enables the control rod 6 and the hollow shaft 4 to rotate synchronously, making the rotation of the debugging plate 2 controllable. This makes it easier to control and select the degreasing method for sheet metal parts. The structure is simple and the operation is convenient.
[0031] In this embodiment, the first conveyor belt 12 transports the sheet metal parts by spraying oil removal, the second conveyor belt 13 performs immersion oil removal on the sheet metal parts, and the feeding conveyor belt 14 transports different sheet metal parts to the inner cavity of the oil removal machine body 1.
[0032] In this embodiment, the shafts of the drive wheels of the first conveyor belt 12 and the second conveyor belt 13 respectively pass through the surface of the degreasing machine body 1 and extend thereto. Two linkage gears 23 are provided on the surface of the degreasing machine body 1, and the two linkage gears 23 are respectively fixedly connected to the shaft surfaces of the drive wheels of the first conveyor belt 12 and the second conveyor belt 13.
[0033] In this embodiment, while the control lever 6 controls the hollow shaft 4 and the groove 5 to rotate the adjustment plate 2, it can also drive the conversion gear 9 to rotate and adjust. A three-phase asynchronous motor is fixedly connected to one side of the degreasing machine body 1. One end of the motor output shaft passes through the surface of the degreasing machine body 1 through a coupling and extends into the interior, and is fixedly connected to the drive wheel of the feeding conveyor belt 14. The other end of the drive wheel of the feeding conveyor belt 14 passes through the surface of the degreasing machine body 1 and is fixedly connected to a gear. A gear rotates on the surface of the degreasing machine body 1. The gear meshes with the linkage gear 23 that is rotatably connected to the first conveyor belt 12. While controlling the adjustment plate 2 to rotate and select the degreasing method for the sheet metal parts, the control lever 6 can also drive the conversion gear 9 to the designated position. Then, the control lever 6 is pushed to slide inside the snap-fit groove 7, so that the conversion gear 9 meshes with the corresponding gear, and then drives the first conveyor belt 12 or the second conveyor belt 13 to rotate through the linkage gear 23. After selecting the degreasing method, the corresponding device is driven to operate. The conversion speed is fast, the structure is simple, and energy is saved.
[0034] In this embodiment, the filter screen 15 filters the degreasing agent. The filtered degreasing agent is discharged through the slot 16 and is then transported to the spraying device and sprayed out by the pressure pump 17 connected to the slot 16 for degreasing. The sprayed degreasing agent continuously falls into the soaking tank 11, and the immersed sheet metal parts are also degreased inside the soaking tank 11. Therefore, a large number of impurities will be mixed in. After being filtered by the filter screen 15, the pressure pump 17 will not be blocked by impurities. Furthermore, the degreasing agents of the two degreasing methods are all in the soaking tank 11, which is convenient for cleaning and replenishment.
[0035] In this embodiment, the inner wall of the degreasing machine body 1 is provided with a groove 18, and a slider 19 is slidably connected to the inner cavity of the groove 18. A connecting rod 20 is fixedly connected to the surface of the second conveyor belt 13. The connecting rod 20 is fixedly connected to the slider 19. The surface of the connecting rod 20 can support the basket for immersion in degreasing and can transport the sheet metal parts in the basket as it rotates. Furthermore, the degreasing agent sprayed by the spraying device above will not spill a large amount on the surface of the second conveyor belt 13, thus maintaining the operation of the second conveyor belt 13 and preventing the degreasing agent from accidentally removing the lubricating oil that maintains the operation of the second conveyor belt 13.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
