Description

Technical Field

[0001] The invention relates to a cavity with a rotation function. Background Art

[0002] When workpieces are cleaned or dried in a through-type device, if the workpieces cannot rotate inside the cleaning chamber, there will be dead corners during cleaning, especially for workpieces with concave structures on the upper surface. During the cleaning process, the accumulated water in the concave structure on the upper surface will seriously affect the cleaning and drying effect and efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect in the prior art that workpieces cannot rotate in the cleaning chamber when being cleaned and dried in a through-type device, especially cannot rotate up and down, and provide a chamber with a rotating function.

[0004] In order to solve the above technical problems, the present invention provides a cavity with a rotating function, which is used to achieve full contact between the workpiece and the fluid used for cleaning and drying and the function of rotating drainage.

[0005] A cleaning chamber with a rotating function includes a frame, a rotating frame and a lifting plate installed horizontally in the frame. A row of rollers for placing workpieces is provided in the rotating frame. An automatic workpiece pressing device is also provided on the rotating frame. The automatic workpiece pressing device includes a spring assembly, a pressure plate and a pressure device mounting plate. One end of the spring assembly is connected to the pressure device mounting plate, and the other end is fixed on the pressure plate. The pressure device mounting plate is fixed on the rotating frame; the pressure plate is placed on the lifting plate. When the lifting plate falls, the pressure plate falls to the upper surface of the workpiece, and the spring remains in a compressed state; the rotating frame rotates around its axis under the drive of the power device.

[0006] Furthermore, the spring assembly includes a spring, a sliding shaft, a sliding sleeve, and a card. One end of the sliding shaft is fixedly connected to the pressure plate, and the other end passes through the sliding sleeve on the clamping device mounting plate. The card is mounted on the end. The spring is sleeved on the outside of the sliding shaft. When the pressure plate falls and there is no workpiece placed on the roller, the card contacts the sliding sleeve, stopping the pressure plate from falling.

[0007] Furthermore, an upper chamber cover and a lower chamber cover are provided outside the rotating frame. The upper chamber cover is provided with a lifting mechanism, and there are two lifting plates, one on each side wall of the upper chamber cover. Of course, the chamber cover can also be omitted. To prevent splashing of cleaning agent, the entire cleaning chamber can be placed in a sealing mechanism.

[0008] Furthermore, when the lifting mechanism lifts the upper chamber cover, the plane where the roller is located is parallel to the upper part of the lower chamber cover, so that automatic loading and unloading can be achieved. The workpiece enters the cleaning chamber directly under the drive of the power device and the roller, and is output from the other side along the roller after cleaning is completed.

[0009] Furthermore, the rotating frame is composed of two retaining rings and a plurality of retaining bars installed between the two retaining rings; the rotating frame is installed in the cavity through a rotating bracket.

[0010] Furthermore, the rotating bracket is composed of rollers, shafts and bearing seats; there are two groups of bearing seats, each group of bearing seats is equipped with a shaft, rollers are provided at both ends of the shaft, and the retaining ring is placed on the two rollers on the same side thereof.

[0011] Furthermore, the retaining ring may have a smooth end and a boss at the other end. The smooth end is placed on a roller, and a chain is mounted on the boss. The chain, driven by the power unit, drives the rotating frame to rotate on the bracket. Alternatively, the retaining ring may have a smooth outer surface and be placed on two rollers on the same side, while a device that engages with the gears of the power unit or multiple stages of conversion are provided inside the retaining ring. As long as the rotating frame can be supported and rotated, the supporting method of the rotating frame and the method of causing the rotating frame to rotate are not specifically limited.

[0012] Furthermore, a sealing ring is provided at the end surface where the upper cavity cover and the lower cavity cover overlap, and the sealing ring can be provided on the upper cavity cover or on the lower cavity cover.

[0013] The working process of the present invention is:

[0014] 1) When the lifting plate is lifted, the pressing plate of the automatic pressing device is lifted, the spring of the automatic pressing device is in a compressed state, and the plane formed by the multiple rollers installed on the rotating frame is parallel to the horizontal plane;

[0015] 2) After the conveying mechanism passes the workpiece through the roller into the cavity, the lifting plate descends, and the pressing plate loses the lifting of the lifting plate. The pressing plate falls to the upper plane of the workpiece under the action of its own gravity and the elastic force of the spring. Since the spring is still in a compressed state, the pressing plate presses the workpiece tightly;

[0016] 3) Start the cleaning or drying process inside the cavity. During cleaning or drying, the workpiece pressed between the roller and the pressing plate rotates around its axis along with the rotating frame;

[0017] 4) After cleaning or drying is completed, the plane formed by the multiple rollers is parallel to the horizontal plane, and the workpiece is sent out of the cavity to the front through the rollers by the conveying mechanism.

[0018] The beneficial effects achieved by the present invention are:

[0019] 1) The present invention uses a rotating frame installed horizontally in the frame to drive the workpiece inside to rotate along the axis of the rotating frame during cleaning or drying, thereby achieving full contact between the workpiece and the fluid used during cleaning and drying and the function of rotational drainage. In addition, during the rotation of the workpiece, the liquid remaining on the upper part of the workpiece can flow out, enhancing the liquid exchange during the cleaning process and the drainage before drying.

[0020] 2) After the workpiece enters from one side of the cavity, it is sent out along the roller after cleaning and enters the next process. It does not need to be taken out from the entrance, thus facilitating automated operation. BRIEF DESCRIPTION OF THE DRAWINGS
