Description

Technical Field

[0001] The utility model is applicable to the technical field of Dacromet coating, and particularly relates to a Dacromet coating centrifugal device. Background Art

[0002] At present, Dacromet, also known as Dacromet and Dicloron, is named zinc-chromium coating in China. It is a new type of anti-corrosion coating with zinc powder, aluminum powder, chromic acid and deionized water as the main components.

[0003] However, when coating the surface of a workpiece with Dacromet for anti-corrosion treatment, the workpiece is often immersed in a frame containing Dacromet coating for coating. After coating, the workpiece needs to be centrifuged and dried using a centrifuge. Between the coating and centrifugal drying processes, workers need to move the workpiece out of the Dacromet coating frame and then move it to the centrifugal dryer for centrifugal treatment. During the movement process, not only are there too many steps required for operation and control, which is time-consuming and labor-intensive, but workers are also very likely to come into contact with any dripping Dacromet coating, which can affect their health. Therefore, we propose a Dacromet coating centrifugal device. Utility Model Content

[0004] The main purpose of the utility model is to provide a Dacromet coating centrifugal device, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A Dacromet coating centrifugal device comprises a mounting frame, a containing frame is fixedly mounted inside the mounting frame, and a centrifugal frame is rotatably mounted inside the containing frame;

[0007] The inner surface of the mounting frame is fixedly provided with a hollow frame at both ends, and a rotating screw is rotatably installed inside the hollow frame through a bearing. The outer surface of each rotating screw is movably sleeved with a lifting sleeve through a thread, and a transmission rod is fixedly installed laterally at the middle end of the outer side of each lifting sleeve. A connecting plate is slidably fitted on the outer surface of each mounting frame, and a side of the transmission rod away from the lifting sleeve is fixedly connected to the outer side of the connecting plate. A connecting frame is fixedly installed on the outer surface of each connecting plate at both ends, and the bottom of the connecting frame is slidably fitted on the top surface of the centrifugal frame.

[0008] A rotating rod is vertically and slidably installed inside the middle of the centrifugal frame, and limit blocks are fixedly installed on the outer end surfaces of the rotating rod. Sliding grooves are opened on both sides of the bottom of the centrifugal frame, and the limit blocks are slidably inserted into the sliding grooves.

[0009] By adopting the above technical solution, the centrifugal frame is lifted and moved out from the inside of the containing frame by the rotating screw rod under the rotation transmission action of the lifting sleeve, and the sliding groove is guided and limited by the limit block. At the same time, the workpieces stacked inside the centrifugal frame can be driven to rotate and centrifuge, reducing the number of operation steps between the workpiece coating and centrifugation steps, and avoiding the random dripping of Dacromet paint when the workpiece is moved, which may cause a safety hazard to the staff.

[0010] As an optional solution of the technical solution of the present application, a limiting block is fixedly installed on the bottom surface of each connecting frame, a rotation groove is opened on the top of the centrifugal frame, and the limiting block is slidably inserted into the rotation groove.

[0011] By adopting the above technical solution, the rationality of the connection transmission between the connecting frame and the centrifugal frame is ensured by the clamping and rotation guiding processing of the limiting clamping block by the rotating groove.

[0012] As an optional solution to the technical solution of the present application, a rotating motor is fixedly installed on the middle surface of the bottom of the mounting frame, and the top of the rotating motor transmission shaft is fixedly connected to the bottom of the rotating rod through a coupling. A servo motor is fixedly installed on the middle surface of the top of each hollow frame, and the bottom of the servo motor transmission shaft is fixedly connected to the top of the rotating screw through a coupling.

[0013] By adopting the above technical solution, the power required for the adjustment transmission of the entire device can be provided by the driving action of the rotating motor and the servo motor.

[0014] As an optional solution of the technical solution of the present application, a limiting groove is provided at the middle end of the side of the hollow frame, and the transmission rod passes through and is slidably inserted into the limiting groove.

[0015] By adopting the above technical solution, the transmission rationality of the entire device is ensured by the guiding and limiting effect of the limiting groove on the transmission rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A Dacromet coating centrifugal device according to the technical solution of the present application connects a sliding plate and a top of a centrifugal frame with a mesh outer wall through a connecting frame, and under the cooperative action of a limit block and a sliding groove, and then under the rotation transmission action of a rotating screw on a lifting sleeve, the limit block can move vertically inside the sliding groove, while driving the centrifugal frame to be lifted and moved out from the inside of the containing frame, and then after the workpiece is removed from the inside of the Dacromet coating liquid, the rotating rod can drive the centrifugal frame to rotate synchronously under the driving action of a rotating motor, and can drive the workpieces stacked inside the centrifugal frame to rotate and centrifuge, thereby reducing the number of operating steps between the workpiece coating and centrifugal steps, and avoiding the arbitrary dripping of Dacromet coating when the workpiece is moved, which may cause a safety hazard to the staff.

[0018] 2. A Dacromet-coated centrifugal device according to the technical solution of the present application is provided with a limiting block at the bottom of the connecting frame and a rotation groove at the top of the centrifugal frame. The limiting block and the rotation groove arranged in an inverted T shape cooperate with each other, so that when the centrifugal frame rotates, the bottom of the connecting frame does not rotate accordingly, thereby ensuring that the connecting frame can transmit the vertical movement force of the lifting sleeve to the top of the containing frame, thereby ensuring the rationality of the vertical movement and circumferential rotation transmission of the centrifugal frame.
