Abstract
Description
Technical Field
[0001] This utility model relates to the field of topcoat production technology, specifically to a raw material grinding device for the production of acrylic drying topcoat. Background Technology
[0002] The most commonly used raw material grinding equipment in the production of acrylic baking topcoats is the sand mill. The sand mill uses a motor to drive a dispersing disc, causing the grinding media to move at high speed within the cylinder, subjecting the raw materials to intense impact and grinding. This grinds the particles in the raw materials to the required fineness, thereby improving the quality and performance of the acrylic baking topcoat.
[0003] The prior art discloses a raw material grinding device for alkyd topcoat production, application number 202322606040.8, including a main body and a grinding disc. A sealing baffle is installed at the lower end of the mounting cover, and a pneumatic cylinder is installed between the sealing baffle and the electric air pump. An integrally formed feed inlet is provided on the surface of the receiving disc, and a locking ring is installed between the receiving disc and the grinding disc. This device addresses the problems of uneven grinding performance, inconvenient operation, and difficult material guiding in traditional raw material grinding devices. The grinding disc drives the receiving disc to rotate, centrifuging the raw material on the surface of the receiving disc to the grinding disc surface for grinding. During operation, the pneumatic cylinder drives the sealing baffle to rise and fall, facilitating material collection. The pneumatic cylinder is rotatably connected to the sealing baffle via bearings, and the rotation of the sealing baffle does not affect the position of the pneumatic cylinder and the electric air pump. The sealing baffle presses down on the feed inlet, sealing it and enclosing the receiving disc, thus facilitating the grinding process.
[0004] However, the existing technology still has the following shortcomings. The above-mentioned device can transmit materials to the grinding position by setting a transmission device, but after the paint raw material is ground, it still needs to be filtered and ground a second time. Unqualified raw materials need to be ground again to ensure the quality of the raw material after grinding. The above-mentioned device also needs to screen the ground raw material and feed it into the grinding a second time, which is more troublesome to use. Therefore, it needs to be improved.

[0023] Please see Figure 1-4 The present invention provides the following technical solution: a raw material grinding device for the production of acrylic drying topcoat, comprising a support mechanism 1 and a grinding mechanism 2, wherein the grinding mechanism 2 is disposed inside the support mechanism 1.
[0024] The grinding mechanism 2 includes a grinding output unit and a filtration circulation unit. The grinding output unit is rotatably connected to the inside of the support mechanism 1, and the filtration circulation unit is located inside the support mechanism 1.
[0025] The support mechanism 1 consists of a support base 101, an insertion interface 102, a feed inlet 103, a pull-out box 104, and a handle 105. The insertion interface 102 is located on the side of the support base 101, the feed inlet 103 is fixedly connected to the top of the support base 101, the pull-out box 104 is inserted into the inside of the insertion interface 102, and the handle 105 is fixedly connected to the surface of the pull-out box 104, playing a major role in bearing load.
[0026] The grinding output unit consists of a grinding disc 201, an air pipe 202, a discharge pipe 203, a grinding tank 204, a discharge port 205, a filter screen 206, a motor 207, a rotating rod 208, and a grinding head 209. The grinding disc 201 is fixedly connected to the inside of the support base 101. The air pipe 202 and the discharge pipe 203 are located inside the grinding disc 201. The grinding tank 204 is located at the top of the grinding disc 201, and the discharge port 205 is located at the bottom of the grinding tank 204. The air pipe 202, the discharge port 205, and the discharge pipe 203 are interconnected, serving a conductive function. The filter screen 206 is fixedly connected to the bottom of the discharge port 205. The motor 207 is fixedly connected to the inside of the feed inlet 103. The rotating rod 208 is rotatably connected to the motor 209. At the bottom of 7, the grinding head 209 is fixedly connected to the bottom of the rotating rod 208, playing the main grinding role. The lower end of the grinding head 209 is attached to the inner wall of the grinding tank 204, playing the grinding role. The filter circulation unit consists of a blower 211, an air inlet pipe 212 and a return pipe 213. The blower 211 is fixedly connected to the side of the support base 101.

In the grinding output unit, the motor 207, fixed inside the inlet 103, drives the rotating rod 208, which in turn drives the grinding head 209, whose lower end is attached to the inner wall of the grinding tank 204, to grind the raw materials within the grinding tank 204 at the top of the grinding disc 201. During grinding, the material passes through the discharge port 205 at the bottom of the grinding tank 204 and is filtered by the filter screen 206. Qualified material is discharged, while unqualified material enters the discharge pipe 203, which is connected to the discharge port 205 and the air pipe 202. At this time, the filter circulation unit comes into play. The blower 211 on the side of the support base 101 blows air into the air pipe 202 through the air inlet pipe 212, blowing the unqualified material in the discharge pipe 203 into the return pipe 213. The return pipe 213 then precisely guides the material between the grinding head 209 and the grinding tank 204 for secondary grinding. This cycle completes the entire raw material grinding work.
