Description

Technical Field

[0001] This utility model relates to the technical field of coating production grinding equipment, specifically a coating production grinding equipment. Background Technology

[0002] In the preparation of coatings, the materials for granular coatings need to be ground into powder particles before further processing, which improves the quality of the coating and helps to increase its adhesion.

[0003] An existing coating production grinding device consists of a grinding chamber, a drive motor, and grinding wheels. During use, because the feed inlet is not equipped with a device to control the material feeding, when a large amount of material is fed in, the material gets stuck between the two rollers, which not only affects the grinding uniformity but also the grinding efficiency. Therefore, a new coating production grinding device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a coating production grinding device that allows materials to be intermittently placed between two rollers, reducing the possibility of material blockage and thus improving grinding efficiency and grinding uniformity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating production grinding device, comprising a base, a grinding box, and two rollers installed inside the grinding box. The upper end of the grinding box is connected to a feeding hopper. A storage box is slidably connected inside the feeding hopper. Two symmetrically distributed support plates are movably connected to the bottom of the storage box via torsion springs. A support rod is fixedly connected between the left and right ends inside the feeding hopper. A vertical rod is fixedly connected to the upper end of the support rod, and a horizontal rod is fixedly connected to the upper end of the vertical rod. Two symmetrically distributed sliders are slidably connected to the outer wall of the horizontal rod. The other ends of the two sliders are movably connected to the two support plates via rotating shafts. An mounting plate is fixedly connected to the outer wall of the storage box. A drive plate is fixedly connected to the front end of the mounting plate. Support blocks are fixedly connected to both the left and right ends of the feeding hopper. Two symmetrically distributed elastic telescopic rods are fixedly connected between the two support blocks and the mounting plate.

[0006] The grinding box is internally fixedly connected to two inclined scrapers that abut against two rollers respectively;

[0007] The front end of the drive board is provided with a drive mechanism.

[0008] In order to drive the drive plate to move up and down, as a preferred embodiment of the coating production grinding device of this utility model, the drive mechanism includes a motor installed on the front end of the grinding box, an eccentric shaft fixedly connected to the output end of the motor, a connecting rod movably connected to the front end of the eccentric shaft through a rotating shaft, and the other end of the connecting rod movably connected to the drive plate through a rotating shaft.

[0009] In order to seal the storage box and prevent material spillage, in a preferred embodiment of the coating production grinding device of this utility model, a first electric push rod is installed on the front end face of the drive plate, and the output end of the first electric push rod passes through the drive plate and is fixedly connected to a cover plate.

[0010] In order to control the opening and closing of the discharge port, as a preferred embodiment of the coating production grinding device of this utility model, a second electric push rod is installed at the bottom of the grinding box, a baffle is fixedly connected to the output end of the second electric push rod, and a discharge port is opened at the lower end of the grinding box.

[0011] In order to collect the ground paint powder, as a preferred embodiment of the paint production grinding device of this utility model, the front end of the grinding box is fixedly connected to the base, and the base is provided with a storage bin located below the discharge port.

[0012] In order to control the operation of each component, as a preferred embodiment of the coating production grinding device of this utility model, a controller is installed on the front end face of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a drive device to reciprocate the movement of a drive plate, mounting plate, and storage bin against an elastic telescopic rod, causing them to move up and down. This brings the opposite ends of two support plates together, stopping the material feeding. When the storage bin moves upward, it drives the two support plates to move in the opposite direction. The two support plates then drive the connected slider to slide in the opposite direction on the outer wall of the crossbar. At this point, the material inside the storage bin falls through the gap between the two support plates into the space between the two rollers, resulting in intermittent material flow between them. This reduces the possibility of material blockage, thereby improving grinding efficiency and uniformity. Attached Figure Description

[0022] The grinding box 2 has two inclined scrapers 16 that abut against two rollers 15 respectively.

[0023] The front end of the driver board 6 is equipped with a drive mechanism.

[0024] In this embodiment: During use, the coating particles to be ground are placed inside the storage box 9. The two rollers 15 are rotated relative to each other by an external drive motor. Then, the drive plate 6, mounting plate 7, and storage box 9 are reciprocated to press the elastic telescopic rod 10 up and down by a drive device. During the downward movement of the storage box 9, the two support plates 14 are driven to move relative to each other, so that the opposite ends of the two support plates 14 abut together. At this time, the feeding stops. When the storage box 9 moves upward, the two support plates 14 are driven to move in the opposite direction. At this time, the two support plates 14 drive the slider 24 connected to them to slide in the opposite direction on the outer wall of the crossbar 13. The material falls between the two rollers 15 through the gap between the two support plates 14, so that the material falls intermittently into the two rollers 15, reducing the possibility of material blockage.

An eccentric shaft 4 is fixedly connected to the output end of the motor 3. A connecting rod 5 is movably connected to the front end of the eccentric shaft 4 through a rotating shaft. The other end of the connecting rod 5 is movably connected to the drive plate 6 through a rotating shaft.

[0026] In this embodiment: the motor 3 can drive the eccentric shaft 4 to rotate, and the rotation of the eccentric shaft 4 drives the connecting rod 5 to move. When the connecting rod 5 moves, it pulls the drive plate 6 to move up and down.

[0027] As a technical optimization of this utility model, a first electric push rod 21 is installed on the front end face of the drive plate 6, and the output end of the first electric push rod 21 passes through the drive plate 6 and is fixedly connected to a cover plate 22.

[0032] In this embodiment, the ground coating powder can be collected through the storage silo 19.

[0033] As a technical optimization of this utility model, a controller is installed on the front end face of the base 1.

[0034] In this embodiment, the controller is electrically connected to the motor 3, the first electric actuator 21, and the second electric actuator 17, and the controller can control the operation of the motor 3, the first electric actuator 21, and the second electric actuator 17.

[0035] Working principle: During use, the paint particles to be ground are placed inside the storage box 9. The two rollers 15 are rotated relative to each other by an external drive motor. Then, the eccentric shaft 4 is driven to rotate by the motor 3. At the same time, the eccentric shaft 4 drives the connecting rod 5 to move. When the connecting rod 5 moves, it pulls the drive plate 6, the mounting plate 7, and the storage box 9 to reciprocate and press the elastic telescopic rod 10 to move up and down, so that the opposite ends of the two support plates 14 abut together. At this time, the feeding stops. When the storage box 9 moves upward, it drives the two support plates 14 to move in the opposite direction. At this time, the two support plates 14 drive the slider 24 connected to them to slide in the opposite direction on the outer wall of the crossbar 13. The material falls between the two rollers 15 through the gap between the two support plates 14, so that the material falls intermittently into the two rollers 15, reducing the possibility of material blockage.
