Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing, in particular to a uniform coating mechanism of a Dacromet production line. Background Art

[0002] The Dacromet production line is a combination of production equipment used to perform Dacromet treatment on metal products. Dacromet is a new surface treatment technology with excellent corrosion resistance, heat resistance, and no hydrogen embrittlement. The Dacromet production line usually includes multiple links such as cleaning, shot blasting, coating, and curing. Among them, the uniform coating mechanism is an important component of the Dacromet production line. The uniform coating mechanism is mainly used to evenly apply the Dacromet coating to the surface of the metal product. Dacromet coating is generally composed of zinc powder, aluminum powder, chromic acid, etc. Through a specific coating process, it can form a dense protective coating on the metal surface.

[0003] Under the current existing technical conditions, the common coating mechanism of the Dacromet production line has exposed some more significant technical shortcomings. Among them, the most prominent is that its installation method is relatively fixed. This feature has caused a series of problems in the actual application process. Specifically, when the coating mechanism needs to be disassembled and cleaned, due to its fixed installation mode, the operation process becomes extremely cumbersome, and it takes a lot of time and energy to complete the disassembly steps. Moreover, during the cleaning process, it is also difficult to thoroughly clean some key parts due to the limitations of the installation structure. Similarly, when maintaining and replacing the coating mechanism, this fixed installation method also brings great inconvenience. The entire maintenance and replacement time is extended, which to a certain extent affects the production efficiency of the Dacromet production line. In order to improve it, a uniform coating mechanism for the Dacromet production line is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5, the uniform coating mechanism of the Dacromet production line includes a bracket 1, a placement rack 3 is rotated on the bracket 1 through a stabilizing rack 4, a rotating motor 2 connected to the placement rack 3 is provided on the bracket 1, a lifting port 7 and a limit port 8 are provided on the bracket 1, a lifting screw 12 is provided in the lifting port 7, a lifting motor 9 connected to the lifting screw 12 is provided on the bracket 1, a lifting nut 14 is provided on the lifting screw 12 through a threaded sleeve of a limit mechanism, a coating rack 10 is provided on the lifting nut 14 through an insertion mechanism, a coating head 16 is provided on the coating rack 10 through a feeding pipe 11, an extrusion groove 22 is provided on the coating rack 10, a limit block 23 is provided in the limit port 8 through an extrusion mechanism in the extrusion groove 22, a cavity is provided inside the placement rack 3, an adjusting screw 18 is provided on the inner wall of the cavity, an adjusting motor 17 is provided on the upper inner wall of the cavity, the adjusting motor 17 is connected to the adjusting screw 18 through a transmission mechanism, a positioning plate 6 is provided on the outside of the placement rack 3, and the positioning plate 6 is connected to the adjusting screw 18 through a connecting mechanism.

[0024] The limiting mechanism includes a limiting rod 13 installed in the lifting port 7, the limiting rod 13 is parallel to the lifting screw 12, and the limiting rod 13 slides through the lifting screw 12. The limiting rod 13 limits the lifting nut 14 to prevent it from rotating with the lifting screw 12.

[0025] The interlocking mechanism includes an insert rod 21 mounted on the coating rack 10. The curved outer wall of the lifting nut 14 is provided with a slot corresponding to the insert rod 21. The structure of the insert rod 21 is already known, and the corresponding slot is easy to imagine, so its specific shape is not described here. Once the insert rod 21 is inserted into the slot, the lifting nut 14 is raised or lowered to raise or lower the coating rack 10. Furthermore, the coating rack 10 is provided with a connecting groove 15 corresponding to the lifting nut 14, and the insert rod 21 is mounted on the inner wall of the connecting groove 15.

[0026] The extrusion mechanism includes a spring 24 disposed within the extrusion groove 22. The ends of the spring 24 are elastically connected to the outer wall of the stopper 23 and the inner wall of the extrusion groove 22, respectively. The spring 24 squeezes the stopper 23 until it enters the stopper opening 8, thereby preventing the coating rack 10 from horizontally disengaging from the lifting nut 14.

[0027] The transmission mechanism includes a driving gear 19 mounted on the output shaft of the adjustment motor 17, and an adjustment screw 18 equipped with a transmission gear that meshes with the driving gear 19. As shown in the figure, both the driving gear 19 and the transmission gear are bevel gears with a vertical meshing relationship. Accordingly, the thread orientation of the adjustment screw 18 is set according to its rotation direction, ensuring that the multiple adjustment nuts 20 can move closer or farther together.

[0028] The connection mechanism includes a connection rod 5 mounted on the adjustment nut 20, which slides through the inner wall of the cavity and is fixedly connected to the positioning plate 6. The connection rod 5 has its own limit to avoid rotating with the adjustment screw 18.

[0029] When the present invention is in use, as shown in the figure, the cylindrical product to be processed can be sleeved on the outside of the placement rack 3, and the adjustment motor 17 is started to cooperate with the driving gear 19 and the transmission gear to drive the adjustment screw 18 to rotate. At this time, the adjustment nut 20 cooperates with the connecting rod 5 to drive the positioning plate 6 to move, squeezing the inner wall of the cylindrical product to be processed, and then the feeding pipe 11 is used to feed the material and the coating head 16 is used to coat the outer wall of the cylindrical product to be processed. At this time, the rotating motor 2 is started to drive the placement rack 3 to rotate, thereby driving the cylindrical product to be processed to rotate. Correspondingly, starting the lifting motor 9 can drive the lifting screw 12 to rotate, so that the coating head 16 can be raised and lowered, thereby realizing a comprehensive coating operation.

[0030] In this solution, the coating head 16 needs to be periodically cleaned, maintained, or replaced. At this time, the limit block 23 in the limit opening 8 is pressed, and the limit block 23 squeezes the spring 24 and shrinks into the extrusion groove 22. Then, the coating frame 10 is moved horizontally relative to the lifting nut 14 to complete the disassembly operation. After disassembly, it is convenient to clean, maintain, or replace it.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
