Technical Field

[0001] This utility model relates to the technical field, specifically to a pretreatment device for nickel plating on the surface of metal alloy powder. Background Technology

[0002] For mechanical parts used in specific applications, when both aesthetics and good corrosion resistance are required, people often solve the problem by electroplating a layer of corrosion-resistant metal onto the surface of the parts, such as chromium plating, nickel plating, etc.

[0003] The effect of electroplating nickel is affected by the cleanliness of the metallized ceramic surface and the purity of the plating solution. Defects such as peeling, blistering, pitting, and black spots are prone to occur. Electroless nickel plating is very sensitive to impurities. Various impurities may exist on the surface of the metal alloy powder, which may affect the effect of nickel plating.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent with publication number CN209974958U and application date of 2019-02-18) discloses a nickel plating pretreatment device, including a base, a bracket set on the base, a housing with an opening on the top surface of the bracket, a conveyor roller set in the middle of the housing, three parallel cleaning support rods set on the top of the housing, each cleaning support rod having a cavity and cleaning nozzles evenly fixed on the bottom surface of the cleaning support rod, a strip groove fixed on the side of the cleaning support rod, a transmission screw set in the strip groove, a drive motor fixed on the side of the housing, limit switches fixed at both ends of the strip groove, a slider threadedly connected to the transmission screw set in the strip groove, a cleaning brush fixed on the bottom surface of the slider, a waste liquid collection tank fixed on the bracket, and a filter screen fixed in the middle of the waste liquid collection tank. The structure of this utility model is reasonable, which helps to improve the efficiency and quality of cleaning. At the same time, it can collect and filter the cleaning liquid, which helps to reduce environmental pollution. It has strong applicability and good practicality.

[0005] While the existing design can solve the above problems, it is too complicated to clean the surface of the parts when nickel plating is required, lacks good applicability, is not stable enough, and requires cleaning before processing. After cleaning, the surface remains damp, which is not conducive to production efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a pretreatment device for nickel plating on the surface of metal alloy powder, in order to solve the problems mentioned in the background art, such as the overly complex surface cleaning design of parts that need to be nickel plated, which lacks good applicability and is not stable in operation, and the need for cleaning before processing, which leaves the surface damp after cleaning, thus hindering production efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for nickel plating on the surface of metal alloy powder, comprising a support base, a sliding fixing frame mounted on the upper surface of the support base, and a sliding transmission mechanism for moving a transmission cleaning plate back and forth inside the sliding fixing frame, the sliding transmission mechanism comprising a drive motor, the drive motor being fixedly mounted on the upper surface of the support base, a fixed rotating disk mounted on the upper output end of the drive motor, a hollow transmission rod mounted on the upper outer surface of the fixed rotating disk, a transmission cleaning plate mounted inside the other end of the hollow transmission rod, a limit sliding rod mounted on the upper surface of the transmission cleaning plate, a sliding inner groove opened at the top of the sliding fixing frame, and an engaging sliding mechanism for rotating a first drying fan mounted inside the sliding inner groove.

[0008] Furthermore, the meshing sliding mechanism includes a heightening support frame, and a rotating fixed frame is installed above the heightening support frame. A second drying fan is installed inside the rotating fixed frame, and a driving fixed gear is installed at the center of the second drying fan. A fixed rack is installed at the top of the limiting sliding rod, and the fixed rack meshes with the driving fixed gear.

[0009] Furthermore, a synchronous transmission belt is installed on the outer surface of the center position of the second drying fan, and the first drying fan is installed inside the rotating fixed frame, with the other side of the synchronous transmission belt slidably installed on the outer surface of the first drying fan.

[0010] Furthermore, a sliding fixing frame is installed on the upper surface of the support base, and the sliding fixing frame is a hollow design. The end of the limiting sliding rod slides along the inside of the sliding fixing frame, and a waste liquid collection box is installed inside the support base.

[0011] Furthermore, the waste liquid collection tank is equipped with a support mesh inside, and the lower surface of the transmission cleaning plate is in contact with the upper surface of the support mesh. Moreover, the waste liquid collection tank and the support mesh are designed as a single unit.

[0012] Furthermore, the inner surface of the hollow transmission rod contacts the upper outer surface of the transmission cleaning plate to form a sliding structure, and the outer surface of the limiting sliding rod contacts the inner surface of the sliding fixing frame to form a sliding structure. Moreover, the fixed rotating disk contacts the upper outer surface of the transmission cleaning plate through the inner surface of the hollow transmission rod to form a transmission structure.

[0013] Furthermore, the outer surface of the fixed rack contacts the outer surface of the driving fixed gear to form a meshing structure, and the outer surface of the limiting sliding rod contacts the inner surface of the sliding inner groove to form a sliding structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the pretreatment device for nickel plating on the surface of metal alloy powder needs to be prepared before nickel plating, the workpiece is first placed above the support screen, the drive motor is started to drive the fixed rotating disk to rotate, and at the same time the rotation of the fixed rotating disk drives the transmission cleaning plate to slide back and forth on the support screen to achieve the purpose of cleaning the surface of the workpiece. The water on the surface of the workpiece will drip through the support screen into the waste liquid collection box for collection. This design makes the outer surface of the workpiece more effectively cleaned.

[0015] Furthermore, the sliding of the transmission cleaning plate drives the fixed rack to move synchronously through the limiting sliding rod. When the fixed rack slides, it drives the second drying fan again through the fixed gear. The second drying fan drives the first drying fan through the synchronous transmission belt. The design of the first and second drying fans being aligned with the support mesh ensures that the workpiece is dried on the outside at the same time during the cleaning operation.

[0016] Furthermore, when the transmission cleaning plate and the limiting sliding rod are driven to slide back and forth, the front end of the limiting sliding rod is nested inside the sliding fixed frame, making the sliding trajectory more stable. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a pretreatment device for nickel plating on the surface of metal alloy powder, comprising a support base 1, a sliding fixed frame 8 installed on the upper surface of the support base 1, and a sliding transmission mechanism for moving a transmission cleaning plate 6 back and forth inside the sliding fixed frame 8, the sliding transmission mechanism comprising a drive motor 2, the drive motor 2 being fixedly installed on the upper surface of the support base 1, a fixed rotating disk 4 being installed at the upper output end of the drive motor 2, a hollow transmission rod 5 being installed on the upper outer surface of the fixed rotating disk 4, a transmission cleaning plate 6 being installed inside the other end of the hollow transmission rod 5, a limiting sliding rod 7 being installed on the upper surface of the transmission cleaning plate 6, a sliding inner groove 9 being opened at the top of the sliding fixed frame 8, and an engaging sliding mechanism for rotating a first drying fan 12 being installed inside the sliding inner groove 9.

[0026] like Figure 1 , Figure 3 , Figure 6 The technical solution shown herein, in order to address the problem that the existing cleaning parts are too complex and lack applicability, discloses the following: A sliding fixing frame 8 is installed on the upper surface of the support base 1, and the sliding fixing frame 8 is a hollow design. The end of the limiting sliding rod 7 slides along the inside of the sliding fixing frame 8. A waste liquid collection tank 3 is installed inside the support base 1, and a supporting strainer 17 is installed inside the waste liquid collection tank 3. The lower surface of the transmission cleaning plate 6 is in contact with the upper surface of the supporting strainer 17, and the waste liquid collection tank 3 and the supporting strainer 17 are an integral design. The inner surface of the hollow transmission rod 5 contacts the upper outer surface of the transmission cleaning plate 6 to form a sliding structure. The outer surface of the limiting sliding rod 7 contacts the inner surface of the sliding fixing frame 8 to form a sliding structure. The fixed rotating disk 4 forms a transmission structure by contacting the inner surface of the hollow transmission rod 5 with the upper outer surface of the transmission cleaning plate 6.

[0027] When the workpiece needs to undergo pretreatment for nickel plating on its outer surface, the workpiece is first placed on top of the support mesh 17 fixedly installed inside the waste liquid collection tank 3. Since the waste liquid collection tank 3 is fixedly installed inside the support base 1, the workpiece remains in the same position. Then, the drive motor 2 fixedly installed on the upper surface of the support base 1 is started. After the drive motor 2 starts, it drives the fixed rotating disk 4 fixedly installed on the upper output end to rotate. A hollow transmission rod 5 is nested on the upper outer surface of the fixed rotating disk 4. Since a transmission cleaning plate 6 is slidably installed inside the other end of the hollow transmission rod 5, the transmission cleaning plate 6 is driven to slide back and forth along the upper surface of the support mesh 17 when the fixed rotating disk 4 is driven to rotate. Since two sets of limiting sliding rods 7 are fixedly installed on both sides of the upper surface of the transmission cleaning plate 6, the limiting sliding rods 7 slide synchronously. Two sets of sliding fixing frames 8 are fixedly installed on the upper surface of the support base 1, and the ends of the limiting sliding rods 7 are nested inside the sliding fixing frames 8. Therefore, the transmission cleaning plate 6 slides horizontally along the inside of the sliding fixing frames 8 through the ends of the limiting sliding rods 7.

[0028] like Figure 2 , Figure 4 , Figure 5 The technical solution shown herein, in order to solve the problem that the surface of the workpiece remains damp after cleaning, making subsequent processing inconvenient, discloses the following: A meshing sliding mechanism includes a heightening support frame 16, and a rotating fixed frame 11 is installed above the heightening support frame 16. A second drying fan 15 is installed inside the rotating fixed frame 11, and a driving fixed gear 14 is installed at the center of the second drying fan 15. A fixed rack 10 is installed at the top of the limiting sliding rod 7, and the fixed rack 10 meshes with the driving fixed gear 14. A synchronous transmission belt 13 is installed on the outer surface of the center of the second drying fan 15, and a first drying fan 12 is installed inside the rotating fixed frame 11. The other side of the synchronous transmission belt 13 is slidably installed on the outer surface of the first drying fan 12. The outer surface of the fixed rack 10 contacts the outer surface of the driving fixed gear 14 to form a meshing structure, and the outer surface of the limiting sliding rod 7 contacts the inner surface of the sliding inner groove 9 to form a sliding structure.

[0029] A heightening support frame 16 is fixedly installed above the support base 1, and two sets of rotating fixed frames 11 are fixedly installed above the heightening support frame 16. A second drying fan 15 is rotatably installed inside the left rotating fixed frame 11, and a driving fixed gear 14 is fixedly installed on the outer surface of the center position of the second drying fan 15. When the limiting sliding rod 7 slides, the fixed rack 10 fixedly installed at the upper end of the limiting sliding rod 7 is driven to slide synchronously, and the sliding of the fixed rack 10 is along the sliding inner groove 9 opened above the sliding fixed frame 8. The fixed rack 10 contacts the driving fixed gear 14 in the rotation trajectory, and the fixed rack 10 and the driving fixed gear 14 are connected. The contact of wheel 14 generates meshing motion, which drives the rotation of fixed gear 14 and causes the second drying fan 15 to rotate circumferentially inside the rotating fixed frame 11. At the same time as the second drying fan 15 rotates, the synchronous transmission belt 13, which is nested and slidably installed on its outer surface, is also driven to rotate. The first drying fan 12 is rotatably installed inside another set of rotating fixed frames 11, and the other end of the inner surface of the synchronous transmission belt 13 is slidably installed on the outer surface of the first drying fan 12. Therefore, the first drying fan 12 is driven to rotate synchronously by the synchronous transmission belt 13 as the second drying fan 15 rotates, and the action direction of the first drying fan 12 and the second drying fan 15 is aligned with the top of the support mesh 17.
