Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a grinder for unburned bricks. Background Art

[0002] Unfired bricks are a new type of wall material made from fly ash, coal slag, coal gangue, tailings, chemical slag, natural sand, and coastal mud (one or more of the above materials) as the main raw materials, without high-temperature calcination. Using a rational scientific formula, a coagulant and trace chemical additives are added in a certain proportion. The particle size, moisture content, and mixing level are optimized using appropriate equipment and processes to achieve an optimal plastic state. The bricks are then formed through high-pressure pressing. Polishing is a necessary step in the production of unfired bricks.

[0003] For example, Chinese patent application No. 202022120003.2 provides a double-sided grinding type unburned brick grinding machine, which places the unburned brick between two clamping blocks, and drives the two clamping blocks to slide relative to each other on the outer surfaces of two limit rods through two reset springs, thereby clamping the unburned brick. When the external power supply is turned on, the threaded rod is driven to rotate by the forward and reverse motors, and the two moving blocks are driven to slide back and forth on the outer surfaces of the sliding rod and the threaded rod, thereby cooperating with the grinding mechanism to achieve multiple grinding and improve the grinding accuracy;

[0004] In the above solution, the grinding cylinder will be worn out after a long period of grinding and needs to be replaced regularly to ensure the grinding effect. In order to solve the above problem, we have designed a fire-free brick grinding machine. Utility Model Content

One of the support frames 2 is provided with a rotating structure, and two support plates 11 are fixedly connected to the base 1. A second screw 13 is rotatably connected to the side wall between the two support plates 11, and four threaded plates 14 are threadedly connected to the second screw 13. A clamping structure is provided between every two threaded plates 14, and a first motor 12 is fixedly connected to the side wall of one of the support plates 11. The output end of the first motor 12 passes through the side wall of the support plate 11 and is fixedly connected to one end of the second screw 13. A limiting rod 18 is fixedly connected to the side wall between the two support plates 11, and the limiting rod 18 passes through the side walls of the four threaded plates 14.

[0026] In an optional embodiment, the rotating structure includes a motor plate 22, which is fixedly connected to the side wall of the support frame 2, and a second motor 19 is fixedly connected to the bottom side wall of the motor plate 22, and the output end of the second motor 19 is fixedly connected to one end of one of the second rotating rods 4, wherein the output end of the other second rotating rod 4 and the second motor 19 are both fixedly connected to a sprocket 21, and the two sprockets 21 are connected by a chain 20.

[0027] It should be noted that the rotation of the second motor 19 causes the sprocket 21 at the output end to rotate, which, under the transmission action of the chain 20, can drive the other second rotating rod 4 to rotate, and one motor controls the rotation of two grinding rollers 5 at the same time.

[0028] In an optional embodiment, the clamping structure includes two fixing rods 15, which are fixedly connected to the side wall between the two threaded plates 14.

[0035] It should be noted that the anti-slip pattern can increase the friction between the clamping plate 17 and the unfired bricks, thereby playing an anti-slip role.

[0036] The working principle of the present invention is: when in use, by rotating the first screw 10 clockwise and counterclockwise, the support frame 2 threadedly connected thereto is rotated left and right, and the first rotating rod 3 is moved out of the clamping hole 6, so that the grinding roller 5 can be replaced, which is very convenient. When grinding, the output end of the first motor 12 rotates forward and reversely, which can drive the two clamping mechanisms to move left and right, and at the same time, the output end of the second motor 19 rotates. Under the action of the sprocket 21 and the chain 20, the two second rotating rods 4 can be rotated at the same time, so that the two grinding rollers 5 can be rotated to complete the grinding of both sides of the unfired brick. There are two clamping mechanisms. When one of the clamping mechanisms is grinding the unfired brick, the unfired brick that has been polished on the other clamping mechanism can be taken down and the unfired brick to be polished can be placed. Compared with having only one clamping structure, it is faster and the efficiency is much improved.
