DEVICE FOR IMMERSING BODIES IN LIQUID

The invention relates to a device for immersing bodies in liquid and for removing excess liquid from bodies using centrifugal force. The device can be applied for painting, impregnation, coating, etc.

Immersion coating devices are also known in the art, for example in EP 172 304 (B 05 C 3/02), U.S. Patents 2,419,260 (118-54) and 3,659,550 (B 05 C 11/12). These devices are much similar in structure. In the following presentation, reference is made to the first-mentioned patent publication. The run-10 gon of the device is formed by a leg 1 and a cylindrical basin 2. The pieces are placed in an immersion basket 12. The immersion basket is mounted at its lower end in a cage 6 and at its upper end in a sealable, openable lid 3 of the basin 2. At the bottom of the basin 2 there is a back from basin 15 2 to tank 20.

The device operates by raising the immersion liquid tank 20 with a working cylinder (not shown) so that the immersion basket 12 and the parts therein are surrounded by the immersion liquid, arrow 21. The tank 20 is then lowered back to the bottom of the basin 2 and the immersion basket 20 12 is rotated. excess liquid sin accumulates away from the pieces.

Only immersion baskets are suitable for the devices described above and thus can handle large quantities of small parts and pieces. Dip coating can also be applied to larger pieces and 25 finished subassemblies. These require piece hangers and fasteners similar to Figures 5, 6. They are made differently according to the shape to be processed. They are placed on the mounting spindle of the device.

Depending on the height of the object to be coated, the required immersion depth varies. In practice, the immersion depth should be freely determined for several reasons.

1. When handling shallow parts with the immersion basket, it is not necessary to immerse the entire basket in immersion liquid. This saves fluid and keeps the basket clean.

. · # 2 · 82396 2. Allows objects of different heights to be immersed so that the necessary piece fasteners and hangers do not come into contact with the immersion fluid used.

* 3. Cope with a lower immersion fluid tank.

„5 Immersion depth locking and rotational transmission in this area is also essential. Intricate shapes or a large number of parts in the immersion basket can be covered up to small holes and the narrowest cavities with immersion liquid if they are allowed to be immersed for some time, or even more effectively if they rotate there gently.

10 Similarly, the whisk used for mixing the immersion liquid, set exactly at the correct height by touching the bottom, can remove sediment deposits.

By means of the device according to the invention, the above-mentioned aspects can be solved. To achieve this, the device according to the invention is characterized by what is stated in the characterizing part of claim 1.

The main advantage of the invention can be considered that it enables the immersion coating of larger pieces using various piece fasteners and hangers. With the invention and many other structural solutions mentioned in this application, the usability of the immersion coating device is improved, the size and weight are reduced, and the price is reduced.

4. The inspection window 21 is closed.

5. The clamping sleeve 26 is opened and the lifting spindle 23 can be lowered so that the body 36 is completely surrounded by the immersion liquid in the tank 3.

4 82396 6. The lifting spindle 23 is raised and locked to the desired height in the upper position by a clamping sleeve 26.

7. The lifting spindle 23 is gently rotated by means of a power device 10 (the speed is infinitely adjustable). At the same time, warm drying air can be led from the opening 20 · 8. The rotation is allowed to continue until the run-off is smoothed out and no more liquid drips from the pieces.

9. The lifting spindle 23 is stopped.

10. The splitter half 7 is opened and the body 36 can be detached 10 from the lifting spindle 23 and removed from its holder 35.

Often errors when using the device are due to too high a viscosity of the liquid, incorrect position of the object in the device, too low a rotational speed. The parts must be placed in the device so that the coating liquid can "run" either downwards or sideways.

Here are some guidelines for making piece fasteners and hangers.

·; 1. Piece clamp - piece combination shall be designed to achieve the best possible dynamic balance.

2. Removing and attaching the part to the holder is quick and easy.

3. Anchorage points such that no untreated points remain.

• · 4. The liquid can "run" freely to the side and down.

8. Sufficiently strong structure of the fastener and hanger.

9. Fasten the mounting screws above the fluid surface.

The body of the device is L-type, made of sturdy angle iron; made. The frame consists of adjacent horizontal and vertical beams 1.2 in Figure 1 mold. Horizontal bars 1 fas-5 upotusnestesäiliölle raise the guide rails 3, so that the container can be easily moved in the directions of arrow 4, and the appropriate kokonaetn remove these guide rail. The horizontal beams 1 are connected at the front and rear by the support bars 5 according to Fig. 2.

10 A splash ring 7 »16 is attached to the vertical beams 2. according to Fig. 2, the vertical beams 2 are connected at their upper ends by a support beam 8. Attached to this is an intermediate plug 6 of the bearing housing tube 9, which also acts as a support for the splash guard 7.16. This provides a solid structure. A motor 10 is attached to a part of the body Talca-15. In order to make it easy to move the device from one place to another, swivel wheels 39 are attached to the horizontal beams 1.

The immersion liquid tank 3, as indicated above, can be moved and removed from the horizontal beams 1. In this way, several tanks and liquids can be used in connection with the same device and work. Liquids can also be stored in sealed containers.

k * According to Figures 1 and 8, the immersion liquid tank has 6 pivoting screw fasteners 11 for holding the removable lid 12 in place. The cover 12 has grooves at corresponding points so that the screw fasteners can be turned and screwed in place by hand. The screw fasteners are placed in a frame 14. This frame also serves as a base for the seal 13 as shown in Figure 8.

Above the spray circle 7,16 in Figure 1 is a rotation mechanism. The rotating mechanism consists of a lifting spindle 23, an ak-10 back lock 26,27, a bushing 28, a bearing housing 9, a pulley 29-, rolling bearings 30, a motor 10 and a transmission belt 31. The bushing 28 is mounted on its rolling bearings 30 and locked as shown in Fig. 9. Attached to the upper end of the blind sleeve 28 is a pulley 29 and a shaft lock 26,27 consisting of a threaded conical sleeve portion 27 and a clamping sleeve 26. The outer cylindrical surfaces of both sleeves are knurled to secure the hand grip, Figure 9. the lifting spindle 23 locks in place.

The lifting spindle 23 passing through the bushing 28 and the shaft lock 26,27 is a straight shaft which can be moved in the direction of its axis of symmetry and rotated about this 25. The upper end of the lifting spindle 23 has a knurled support 33 for the hand grip and the lower end is turned with a securing groove 34 for piece fasteners, Fig. 9. Figures 4-7 show different piece fasteners. Figure 4 shows a painting bracket 35 connected to the device for painting a palm made of a square tube. The crank is set at a slight angle to allow the paint to "run" better. Figure 5 shows a hanger suitable for mm pulleys. Attachment to the lifting spindle 23 is also shown.
