Description

Technical Field

[0001] This utility model relates to the field of polyester powder coating production technology, and in particular to a grinding device for polyester powder coating production and processing. Background Technology

[0002] Polyester powder coating is a thermosetting powder coating with hydroxyl polyester resin as the main component. It has good weather resistance and decorative properties. It is commonly used in building materials, home appliances and general industrial fields, such as doors and windows, road signs, automobile and motorcycle parts, etc. Polyester powder coating is composed of hydroxyl polyester resin, curing agent, pigment, filler and additives. It has good weather resistance and is not prone to yellowing. The paint film has high fullness. When processing polyester powder coating, a grinding device is needed to grind the polyester powder. Grinding uses abrasive particles coated or embedded on a grinding tool. The relative movement between the grinding tool and the workpiece under a certain pressure is used to finish the processed surface.

[0003] To address this, patent publication CN212549739U discloses a grinding device for powder coating processing, comprising a housing, a worm gear fixedly mounted at the end of the output shaft of a stepper motor, a support mechanism between the lower outer end of the worm gear and the housing, worm wheels rotatably mounted on one side of the housing, one end of a transmission shaft passing through a limiting bearing on the housing and extending to the inner side of the housing, rollers fixedly mounted on the outer side of the transmission shaft inside the housing, a gap being provided between two rollers, and multiple grinding teeth uniformly welded to the outer surfaces of the two rollers, with the grinding teeth on the two rollers being staggered. This invention achieves the grinding effect on blocky coatings through the opposite rotation of two rollers, and the ground coating is mixed with water in powder form, thus improving the quality of the coating.

[0004] 1. The above-mentioned grinding device for powder coating processing proposes to achieve the grinding effect of block coating by rotating two rollers in opposite directions. The ground coating is mixed with water in the form of powder to improve the quality of the coating. However, the box is prone to displacement during discharge, which affects the collection of powder.

[0005] 2. During grinding, some powder will be adsorbed on the grinding wheel. This powder is difficult to handle and will also make it difficult to completely discharge the powder. Utility Model Content

[0006] The purpose of this utility model is to provide a grinding device for the production and processing of polyester powder coatings, so as to solve the defects of existing grinding devices for the production and processing of polyester powder coatings, which are difficult to limit the position of the box and difficult to clean the grinding wheel.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grinding device for polyester powder coating production and processing, including support legs;

[0008] A mounting block is installed at the top of the support leg, a base plate is installed at the bottom of the support leg, a box is installed at the top of the base plate, and a limit structure is installed on both sides of the box.

[0009] The limiting structure includes a connecting plate, a spring, a first limiting plate guide rod, and a second limiting plate. The second limiting plate is installed on one side of the top of the base plate, the connecting plate is installed on one side of the top of the base plate, a spring is installed on one side of the connecting plate, and the first limiting plate is installed on one side of the spring.

[0010] The mounting block has a housing at its top and an outlet at its bottom. A filter structure is installed inside the outlet. An inlet is installed at the top of the housing. A guide plate is installed inside the housing. A grinding wheel is installed inside the housing. A servo motor is installed at one end of the grinding wheel. Cleaning structures are installed on both sides inside the housing.

[0011] In use, the material is first loaded into the housing through the inlet. The servo motor then drives the grinding wheel to rotate, which grinds the material. After grinding, the material is guided by the guide plate to the next set of grinding wheels for further grinding. The grinding effect can be improved by grinding three times. Finally, the powder is discharged into the housing through the outlet.

[0012] Furthermore, the cleaning structure includes a fixing block, a brush, a fixing plate, and fixing screws. The fixing block is installed on both sides inside the housing. A brush is installed on one side of the fixing block. Fixing plates are installed at both the top and bottom of the fixing block, and fixing screws are installed on one side of the fixing plates. The polishing wheel can be cleaned by the brush.

[0013] Furthermore, the outer sidewall of the fixing screw is uniformly provided with external threads, and the inner sidewall of the fixing plate is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the fixing plate are threadedly connected, and the fixing block can be fixed by the fixing screw.

[0014] Furthermore, the spring is helical in shape, and the spring and the first limiting plate form an elastic connection, thus the spring is elastic.

[0015] Furthermore, a guide rod is installed on one side of the first limiting plate, and the guide rod is symmetrically distributed about the central axis of the first limiting plate, so that the guide rod can guide the first limiting plate.

[0016] Furthermore, the filtration structure includes a filter screen, a filter box, a cover, a handle, and a scraper. The filter box is installed at the bottom of the outlet. A cover is installed on one side of the filter box, a handle is installed on one side of the cover, a filter screen is installed on one side of the cover, and a scraper is installed on one side inside the filter box. The discharged material can be filtered through the filter screen.

[0017] Furthermore, a slot is provided on one side of the filter box, and a locking block is provided on one side of the cover. The filter box and the cover form a locking structure, which facilitates disassembly.

[0018] The grinding device for polyester powder coating production and processing provided by this utility model has the following advantages: it can achieve better grinding effect by using multiple sets of grinding wheels, and at the same time, it can limit the box body by the cooperation of the first limiting plate and the second limiting plate to prevent the box body from shifting, allowing the box body to collect powder, and at the same time, it can clean the grinding wheels with a brush.

[0019] By installing a connecting plate on one side of the top of the base plate, the connecting plate and the first limiting plate are connected by a spring and a guide rod. The spring is elastic, and its elasticity will drive the first limiting plate to move. After the box is placed between the first limiting plate and the second limiting plate, the first limiting plate and the second limiting plate can clamp the box in the middle to prevent the box from shifting during material collection. The guide rod can extend and retract, and the guide rod can guide the movement of the first limiting plate to prevent the first limiting plate from shifting. In this way, the grinding device for polyester powder coating production and processing can easily limit the position of the box.

[0020] By installing fixing plates on both sides inside the outer casing, and the fixing plates and fixing screws forming a threaded connection, the fixing plates and brushes can be fixed by fixing screws. When the grinding wheel is grinding, after the grinding wheel rotates to the position of the brush, the brush can clean the grinding wheel and remove the powder on the grinding wheel to prevent the powder from adhering to the grinding wheel. This achieves the purpose of making it easy to clean the grinding wheel of the grinding device used in the production and processing of polyester powder coatings. Attached Figure Description
