Description

Technical Field

[0001] This utility model relates to the field of water-based paint processing technology, specifically to a grinding device for processing water-based paint. Background Technology

[0002] Water-based paint is an environmentally friendly coating that uses water as the main diluent. Compared with traditional oil-based paint (which uses organic solvents as diluents), it has a lower VOC (volatile organic compound) content and is more friendly to human health and the environment.

[0003] To make water-based paints more delicate, the raw materials need to be ground during the processing. Existing grinding equipment has a relatively simple grinding method, and the grinding product is obtained through a single grinding. This can easily lead to insufficient grinding, which greatly affects the processing effect of water-based paints. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a grinding device for processing water-based paint, which can perform double grinding on water-based paint raw materials, making the grinding more thorough and greatly improving the grinding effect.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a grinding device for processing water-based paint, including a support frame, a grinding jar fixedly connected to the upper end of the support frame, a discharge port provided at the lower end of the grinding jar, a first grinding disc fixedly connected to one end of the grinding jar, a feed hole provided at the center of the first grinding disc, an L-shaped feed pipe fixedly connected to one end of the grinding jar communicating with the feed hole, a rotating shaft rotatably connected inside the L-shaped feed pipe and arranged coaxially with the feed hole, a first motor for driving the rotating shaft to rotate fixedly connected to the support frame, and one end of the rotating shaft fixedly connected to the first motor. A second grinding disc is fixedly connected to one side of the first grinding disc, and a grinding gap is provided between the first grinding disc and the second grinding disc; a grinding cylinder is inserted into the grinding jar and arranged coaxially, and a grinding pad is fixedly connected to the inner wall of the grinding cylinder; a fixed cylinder is fixedly connected to the other end of the second grinding disc and arranged coaxially, and at least one movable sleeve is fixedly connected to the outer wall of the fixed cylinder; a movable block is slidably inserted into one end of the movable sleeve, and a grinding block that cooperates with the grinding pad is fixedly connected to one end of the movable block extending outside the movable sleeve; an adjustment mechanism for driving the movable block to slide is provided inside the fixed cylinder.

[0006] As an improvement, the adjustment mechanism includes a telescopic cylinder fixedly connected inside the fixed cylinder, and adjusting arms are hinged to both ends of the movable block. The two adjusting arms are respectively hinged to the output end of the telescopic cylinder and the outer wall of the cylinder body.

[0007] As an improvement, a spiral guide auger that mates with the L-shaped feed pipe and the inner wall of the feed hole is fixedly sleeved on the outer wall of the rotating shaft.

[0008] As an improvement, a screen plate is fixedly connected between the two grinding pads on the grinding cylinder.

[0009] As an improvement, an external gear ring is rotatably connected to one end of the grinding jar, a gear that meshes with the external gear ring is rotatably connected inside the grinding jar, a second motor that drives the gear to rotate is fixedly connected to the grinding jar, a limiting slot is provided on the inner wall of the external gear ring, a limiting insert that mates with the limiting slot is fixedly connected to one end of the grinding cylinder, and an installation hole that mates with the grinding cylinder is provided at one end of the grinding jar.

[0010] As an improvement, a brush plate is fixedly connected to the outer wall of the fixed cylinder.

[0011] The advantages of this utility model compared with the prior art are as follows: After the raw material enters between the first grinding disc and the second grinding disc through the L-shaped feed pipe, the first grinding disc and the second grinding disc rotate to achieve preliminary grinding. The preliminarily ground raw material falls into the grinding cylinder, and the grinding block rotates to further grind the raw material through the rotation of the second grinding disc. Through two grinding methods, the raw material is double-ground, which greatly improves the grinding effect. Attached Figure Description
