Description

Technical Field

[0001] This utility model relates to the field of parts processing equipment technology, and in particular to a parts immersion and spin-drying device. Background Technology

[0002] In industrial coating processes, immersion and spin-drying are key steps to ensure the uniformity and quality of coatings on the surface of parts. Parts are completely immersed in the immersion liquid through an immersion device to achieve coverage, and then excess immersion liquid is removed by high-speed spin-drying, thereby forming a uniform film thickness.

[0003] In daily production, common impregnation and spin-drying devices employ a matching structure of a cylindrical paint tank and an impregnation basket. The cylindrical paint tank requires a large amount of impregnation liquid to reach the required liquid level. The impregnation basket is also cylindrical, and its internal parts are impregnated and then rotated and spin-dried as a whole. During this process, the impregnation basket is driven by a drive mechanism to rotate, relying on centrifugal force to discharge excess impregnation liquid from the surface of the parts. However, the combination of the cylindrical paint tank and the impregnation basket requires a large amount of impregnation liquid to meet the liquid level requirements, resulting in high impregnation liquid consumption and high production costs. Furthermore, during spin-drying, the centrifugal force in the central area of ​​the cylindrical impregnation basket is much lower than that in the outer area, causing residual impregnation liquid on the surface of the central parts to not be effectively removed, resulting in poor coating uniformity and easy scrapping of parts. Therefore, there is an urgent need for a part impregnation and spin-drying device to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a part immersion and spin-drying device, which solves the technical problems of large amount of immersion liquid used and uneven spin-drying caused by parts accumulating in the central area of ​​the immersion basket.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A parts immersion and spin-drying device, comprising:

[0007] An impregnation tank with an open top, wherein the impregnation tank has a cavity inside;

[0008] A central column is centrally located within the cavity;

[0009] A spin-drying basket is provided with a plurality of filter holes. The spin-drying basket is rotatably disposed in a cavity. The spin-drying basket includes an outer frame, an inner frame, and an annular bottom plate. The inner frame is sleeved on a central column. The outer frame is coaxially sleeved on the outside of the inner frame. The annular bottom plate is disposed at the bottom of the outer frame and the inner frame. The inner and outer edges of the annular bottom plate are respectively connected to the inner frame and the outer frame.

[0010] A drive mechanism for driving the spin-drying basket to rotate.

[0011] Based on the above structure, the principle of the part impregnation and spin-drying device is as follows: First, the part to be impregnated is placed in the spin-drying basket, and the impregnation liquid is injected into the cavity to a preset height. The impregnation liquid enters the spin-drying basket through the filter holes. Next, the drive mechanism is activated to drive the spin-drying basket to rotate around the axis of the central column in the cavity at a preset impregnation speed, so that the part in the spin-drying basket is fully in contact with the impregnation liquid, ensuring that the part is fully impregnated. The central column is set to reduce the amount of impregnation liquid used in the cavity and improve economy. After the part is impregnated, the spin-drying basket and the impregnation liquid are removed from the cavity. The process involves separating the impregnation liquid from the coating. A drive mechanism drives the spin-drying basket to perform the spin-drying operation. The spin-drying basket rotates around the axis of the central column within the cavity at a preset spin-drying speed. The centrifugal force generated by the rotation of the spin-drying basket is used to remove excess impregnation liquid from the surface of the parts. The impregnation liquid is discharged through filter holes. The hollow design of the spin-drying basket prevents parts from accumulating in the middle of the basket. When the spin-drying basket rotates, the parts avoid the area in the middle of the basket where the centrifugal force is relatively small. This prevents the parts from being unable to be effectively spin-dried due to being in a weak centrifugal force area, thereby ensuring a uniform overall coating thickness and improving the spin-drying quality.

[0012] Furthermore, in this application, a part impregnation and spin-drying device is provided, wherein the filter holes are disposed on an outer frame, an inner frame, and an annular base plate. On the outer frame and the inner frame, the filter holes are respectively spaced apart along the axial and circumferential directions of the spin-drying basket, and on the annular base plate, the filter holes are respectively spaced apart along the radial and circumferential directions of the annular base plate. As a preferred embodiment of this application, in this part impregnation and spin-drying device, the filter holes are used for the impregnation liquid to enter and exit the spin-drying basket. The filter holes on the outer frame, the inner frame, and the annular base plate are all evenly spaced, which allows the impregnation liquid to smoothly enter the interior of the spin-drying basket during the impregnation process and fully contact the parts placed in the spin-drying basket, ensuring that all parts of the parts are evenly coated with the impregnation liquid, achieving a good impregnation effect. During the spin-drying process, the evenly distributed filter holes facilitate the discharge of excess impregnation liquid from different directions and positions through the filter holes under the action of centrifugal force, ensuring a uniform spin-drying effect, making the coating thickness on the part surface more uniform, and improving the production quality and consistency of the parts.

[0013] Furthermore, the part immersion and spin-drying device of this application further includes: an adjustment mechanism, which is used to adjust the height of the spin-drying basket in the cavity. The adjustment mechanism includes: a liftable platform and a lifting drive device. The immersion tank is disposed on the liftable platform, and the lifting drive device is used to lift the liftable platform. As a preferred embodiment of this application, the part immersion and spin-drying device of this application uses the lifting drive device to drive the liftable platform to adjust the height of the spin-drying basket in the cavity, thereby separating the spin-drying basket from the immersion liquid. Since the immersion tank is installed on the liftable platform, the immersion tank will move up and down with the liftable platform, while the spin-drying basket is placed in the cavity of the immersion tank. When it is necessary to remove the spin-drying basket from the immersion liquid, the lifting drive device is activated, causing the liftable platform to move away from the spin-drying basket. The liftable platform drives the immersion tank to move away from the spin-drying basket, thus completing the separation of the spin-drying basket from the immersion liquid.

[0014] Furthermore, in a parts immersion and spin-drying device of this application, the liftable platform is provided with a receiving trough corresponding to the immersion barrel, the receiving trough being used to accommodate the immersion barrel. As a preferred embodiment of this application, the receiving trough of the parts immersion and spin-drying device of this application can accurately place the immersion barrel at a preset position on the liftable platform. When the immersion barrel needs to be cleaned or replaced, the operator can remove the immersion barrel from the liftable platform, and during installation, the immersion barrel can be accurately placed in the correct position; and when the liftable platform rises or falls, the receiving trough can radially limit the immersion barrel, preventing the immersion barrel from moving on the liftable platform, thereby ensuring the safe operation of the device.

[0015] Furthermore, in a parts immersion and spin-drying device of this application, a limiting edge is provided at the upper opening of the immersion tank. The limiting edge extends radially outward along the immersion tank, and an extension corresponding to the limiting edge is provided on the outer side wall of the outer frame. When the spin-drying basket is placed into the cavity, the limiting edge is used to limit the spin-drying basket. As a preferred embodiment of this application, when the spin-drying basket is placed into the cavity, the limiting edge and the extension work together to limit the spin-drying basket, preventing the spin-drying basket from excessively entering the cavity and avoiding collision between the spin-drying basket and the bottom of the immersion tank, thereby protecting the structural integrity of the spin-drying basket and the immersion tank.

[0016] Furthermore, in this application, a part immersion and spin-drying device includes a driving mechanism comprising: a rotation driving device and a set of clamping parts. The set of clamping parts is evenly spaced along the circumference of the spin-drying basket, and the clamping parts are radially adjustable along the spin-drying basket. Each clamping part has a clamping groove corresponding to an extension portion, the groove being used to accommodate the extension portion. The rotation driving device is used to rotate the set of clamping parts around the axis of a central column. As a preferred embodiment of this application, the part immersion and spin-drying device, with its set of clamping parts evenly spaced along the circumference of the spin-drying basket and radially adjustable, ensures uniform force distribution on the spin-drying basket during clamping, preventing deformation or damage. The uniform force distribution during rotation avoids the risk of deformation due to stress concentration at a single point. The clamping parts can be adjusted according to the actual size of the spin-drying basket to accommodate different specifications. When clamping the spin-drying basket, the clamping parts can be radially moved to... The clamping part is positioned close to the spin-drying basket to grip it. When the basket is not needed, the clamping part can move radially away from it for easy loading and unloading. During the clamping process, the extension part cooperates with the clamping groove to securely grip the basket, ensuring that it will not loosen or fall off during rotation, thus guaranteeing the stability and safety of the device. After the clamping part grips the basket, the rotation drive device is activated, causing the clamping part to rotate around the axis of the central column, which in turn drives the spin-drying basket to rotate, thus realizing the immersion and spin-drying operations of the parts.

[0017] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0018] The purpose of this invention is to provide a part impregnation and spin-drying device. By using a central column design, the amount of impregnating liquid used is reduced, thus improving economy. The double-layer hollow annular spin-drying basket is used to prevent parts from accumulating in the central area of ​​the spin-drying basket during the part spin-drying process, which would prevent residual impregnating liquid from being effectively removed from the part surface, thus ensuring uniform coating thickness. Furthermore, the adjustable height adjustment mechanism is used to adapt to the impregnation needs of parts of different sizes, improving the versatility of the device. Attached Figure Description

Detailed Implementation

[0023] like Figure 1 , 2 As shown in Figure 3, a part immersion and spin-drying device includes:

[0024] An impregnation tank 1 with an open top, wherein the impregnation tank 1 is provided with a cavity 10;

[0025] Central column 2, which is centrally located within the cavity 10;

[0026] A spin-drying basket 3 is provided with a plurality of filter holes 30. The spin-drying basket 3 is rotatably disposed in a cavity 10. The spin-drying basket 3 includes an outer frame 31, an inner frame 32, and an annular bottom plate 33. The inner frame 32 is sleeved on the central column 2. The outer frame 31 is coaxially sleeved on the outside of the inner frame 32. The annular bottom plate 33 is disposed at the bottom of the outer frame 31 and the inner frame 32. The inner and outer edges of the annular bottom plate 33 are respectively connected to the inner frame 32 and the outer frame 31.

[0027] Drive mechanism 4, which is used to drive the spin-drying basket 3 to rotate.

[0028] Based on the above structure, the principle of the part impregnation and spin-drying device is as follows: First, the part to be impregnated is placed in the spin-drying basket 3, and the impregnation liquid is injected into the cavity 10 to a preset height. The impregnation liquid enters the spin-drying basket 3 through the filter holes 30. Next, the drive mechanism 4 is started, driving the spin-drying basket 3 to rotate around the axis of the central column 2 in the cavity 10 at a preset impregnation speed, so that the part in the spin-drying basket 3 is fully in contact with the impregnation liquid, ensuring that the part is fully impregnated. The central column 2 is set to reduce the amount of impregnation liquid used in the cavity 10 and improve economy. After the part is impregnated, the spin-drying basket 3... Separated from the impregnation liquid, the spin-drying basket 3 is driven by the drive mechanism 4 to perform spin-drying. The spin-drying basket 3 rotates around the axis of the central column 2 in the cavity 10 at a preset spin-drying speed. The centrifugal force generated by the rotation of the spin-drying basket 3 is used to spin-dry the excess impregnation liquid on the surface of the parts. The impregnation liquid is discharged through the filter hole 30. The hollow design of the spin-drying basket 3 prevents the parts from accumulating in the middle of the spin-drying basket 3. When the spin-drying basket 3 rotates, the parts avoid the area with less centrifugal force in the middle of the spin-drying basket 3. This prevents the parts from being unable to be effectively spun dry due to being in the area with weak centrifugal force, thereby ensuring that the overall coating thickness of the parts is uniform and improving the spin-drying quality.

[0029] In this embodiment, the filter holes 30 are disposed on the outer frame 31, the inner frame 32, and the annular base plate 33. On the outer frame 31 and the inner frame 32, the filter holes 30 are respectively spaced apart along the axial and circumferential directions of the spin-drying basket 3. On the annular base plate 33, the filter holes 30 are respectively spaced evenly along the radial and circumferential directions of the annular base plate 33. The filter holes 30 are used for the impregnation liquid to enter and exit the spin-drying basket 3. The filter holes 30 on the outer frame 31, the inner frame 32, and the annular base plate 33 are all spaced apart, which allows the impregnation liquid to smoothly enter the interior of the spin-drying basket 3 during the impregnation process and fully contact the parts placed in the spin-drying basket 3. This ensures that all parts of the parts are evenly coated with the impregnation liquid, achieving a good impregnation effect. During the spin-drying process, the evenly distributed filter holes 30 facilitate the discharge of excess impregnation liquid from different directions and positions on the surface of the parts under the action of centrifugal force, ensuring a uniform spin-drying effect and making the coating thickness on the surface of the parts more uniform, thereby improving the production quality and consistency of the parts.

By driving the liftable platform 51 with the lifting drive device to adjust the height of the spin-drying basket 3 within the cavity 10, the spin-drying basket 3 is separated from the impregnation liquid. Since the impregnation tank 1 is mounted on the liftable platform 51, the impregnation tank 1 will move up and down together with the liftable platform 51. The spin-drying basket 3 is placed within the cavity 10 of the impregnation tank 1. When it is necessary to remove the spin-drying basket 3 from the impregnation liquid, the lifting drive device is activated, causing the liftable platform 51 to move away from the spin-drying basket 3. The liftable platform 51 drives the impregnation tank 1 to move away from the spin-drying basket 3, thus completing the separation of the spin-drying basket 3 from the impregnation liquid. The lifting drive device adopts a hydraulic drive device (not shown). This design also allows the device to flexibly adjust the position of the spin-drying basket 3 in the impregnation liquid according to the impregnation requirements of different parts, thereby improving the versatility of the device.

The receiving groove 50 can accurately place the immersion tank 1 at a preset position on the lifting platform 51. When the immersion tank 1 needs to be cleaned or replaced, the operator can remove the immersion tank 1 from the lifting platform 51, and it can also be accurately placed in the correct position during installation. Furthermore, when the lifting platform 51 rises or falls, the receiving groove 50 can radially limit the immersion tank 1, preventing it from moving on the lifting platform 51 and ensuring the safe operation of the device. The lifting platform 51 is provided with a stop 52, which is arranged along the circumference of the immersion tank 1. The stop 52 is located on the outside of the immersion tank 1, and the outer wall of the immersion tank 1 and the inner wall of the stop 52 abut against each other radially.

[0032] In this embodiment, a limiting edge 11 is provided at the upper opening of the impregnation tank 1. The limiting edge 11 extends radially outward along the impregnation tank 1. An extension 311 corresponding to the limiting edge 11 is provided on the outer side wall of the outer frame 31. When the spin-drying basket 3 is placed into the cavity 10, the limiting edge 11 is used to limit the spin-drying basket 3. When the spin-drying basket 3 is placed into the cavity 10, the limiting edge 11 and the extension 311 work together to limit the spin-drying basket 3, prevent the spin-drying basket 3 from entering the cavity 10 excessively, and avoid the spin-drying basket 3 from colliding with the bottom of the impregnation tank 1, thereby protecting the structural integrity of the spin-drying basket 3 and the impregnation tank 1.

The set of clamping parts 41 are evenly spaced along the circumference of the spin-drying basket 3. The clamping parts 41 are movably adjustable along the radial direction of the spin-drying basket 3.

The rotation driving device is used to rotate the set of clamping parts 41 around the axis of the central column 2. A set of clamping parts 41 are evenly spaced along the circumference of the spin-drying basket 3, and the clamping parts 41 are adjustable and movable along the radial direction of the spin-drying basket 3. This design ensures that the spin-drying basket 3 is subjected to uniform force when clamped, avoiding deformation or damage to the spin-drying basket 3; the spin-drying basket 3 is subjected to uniform force when rotating, avoiding the risk of deformation caused by stress concentration at a single point. The clamping parts 41 can be adjusted according to the actual size of the spin-drying basket 3 to accommodate different specifications of spin-drying basket 3. When it is necessary to clamp the spin-drying basket 3, the clamping parts 41 can move radially closer to the spin-drying basket 3 to achieve clamping of the spin-drying basket 3; when When the spin-drying basket 3 is not needed, the clamping part 41 can move radially away from the spin-drying basket 3, facilitating the loading and unloading of the spin-drying basket 3.
