Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic raw material production and processing, in particular to a ceramic raw material grinding machine. Background Art

[0002] Common ceramic raw material grinders use two grinding discs rotating at high speed for grinding. Since the grinding discs are in surface contact, the friction resistance is greater and more energy is consumed. Secondly, the grinding of the two grinding discs against each other may produce particles. If they are not cleaned or handled in time, the particles may be mixed into the ceramic raw materials. In addition, the amount of ceramic raw materials that can be ground at a time is also small, and the ground ceramic raw materials are also likely to remain between the grinding discs. Utility Model Content

[0003] In order to solve the problems in the above-mentioned prior art, the utility model proposes a ceramic raw material grinder, which uses a grinding roller to crush and grind the ceramic raw material. The resistance between the grinding roller and the shell is smaller and more energy-efficient, and a larger amount of ceramic raw material can be ground at one time. The ceramic raw material is easy to take out and not easy to remain.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a ceramic raw material grinder, comprising a shell, a first motor, a driving shaft, a rotating arm, a connecting rod and a grinding mechanism; a feed port is provided at the top of the shell, the first motor is fixed at the bottom of the shell, the driving shaft extends into the shell from the bottom of the shell, the first motor drives the driving shaft to rotate, a rotating arm is provided at the top of the driving shaft, the bottom of the end of the rotating arm is connected to the grinding mechanism through the connecting rod, the grinding mechanism comprises a bracket and a grinding roller, the bracket is fixed to the bottom of the connecting rod, the grinding roller is installed on the bracket, and the grinding roller is rotatable; the grinding roller contacts the bottom of the inner wall of the shell, and the bottom of the inner wall of the shell is a grinding surface. The first motor drives the driving shaft to rotate, drives the rotating arm to rotate, and causes the grinding roller to rotate around the driving shaft. The grinding roller rotates around its own axis due to friction, and crushes and grinds the ceramic raw materials. The contact between the grinding roller and the bottom of the inner wall of the shell is line contact, which has less resistance and is more energy-efficient. It will not block the input and removal of ceramic raw materials, and the grinding roller can be pushed at any time to leave space for convenient removal of ceramic raw materials, which is more convenient to use.

[0005] Furthermore, the grinding mechanism further includes a second motor and a brush shaft, both of which are mounted on the bracket, and the brush shaft surface is provided with bristles, and the second motor drives the brush shaft to rotate; when the brush shaft rotates, the ceramic raw material in the housing is swept toward the grinding roller, so as to avoid the ceramic raw material from accumulating in front of the grinding roller and being constantly pushed by the grinding roller, resulting in poor grinding effect, and can also sweep the compacted ceramic raw material to avoid agglomeration.

[0006] Furthermore, it also includes a support roller, which is arranged at the top of the end of the rotating arm and abuts against the inner top wall of the shell. The ceramic raw material may lift the grinding roller and cause the rotating arm to bend upward, resulting in an increase in the gap between the grinding roller and the bottom of the shell, resulting in poor grinding effect. The support roller can be arranged to abut against the rotating arm to prevent the grinding roller from being lifted up.

[0007] Furthermore, a discharge port is provided at the bottom of the shell, an embedded sieve plate is installed at the discharge port, sieve holes are evenly arranged on the embedded sieve plate, and a raw material collecting tank is provided below the embedded sieve plate. Ceramic raw materials with sufficiently small particle size can pass through the sieve holes and fall into the raw material collecting tank.

[0008] Furthermore, the top surface of the embedded sieve plate is flush with the bottom surface of the inner wall of the shell to avoid height difference. If it is higher than the bottom surface of the inner wall, it may interfere with the grinding mechanism. If it is lower than the bottom surface of the inner wall, a groove is formed, which may easily cause ceramic raw materials to accumulate and block the sieve holes.

[0009] Furthermore, a brush ring is fixed at the bottom of the driving shaft, and when the driving shaft rotates, the brush ring is driven to rotate, and the bristles on the brush ring sweep the ceramic raw material toward the grinding mechanism.

[0010] Furthermore, a slope is provided on the top of the driving shaft to prevent the ceramic raw material from staying on the top of the driving shaft when poured in, and ensure that the ceramic raw material falls into the bottom of the shell.

[0011] The beneficial effects of a ceramic raw material grinding machine of the utility model are as follows: a first motor is provided to drive the driving shaft to rotate, drive the rotating arm to rotate, and make the grinding roller rotate around the driving shaft. Due to friction, the grinding roller will rotate around its own axis to crush and grind the ceramic raw material. The contact between the grinding roller and the bottom of the inner wall of the shell is line contact, which has less resistance and is more energy-saving. It will not block the input and removal of the ceramic raw material, and the grinding roller can be pushed at any time to leave space for convenient removal of the ceramic raw material, which is more convenient to use; a brush shaft is provided, and the second motor drives the brush shaft to rotate; when the brush shaft rotates, the ceramic raw material in the shell is swept toward the grinding roller, so that the ceramic raw material is prevented from accumulating in front of the grinding roller and being constantly pushed by the grinding roller, resulting in poor grinding effect, and the compacted ceramic raw material can also be swept to avoid agglomeration; a discharge port is provided at the bottom of the shell, and an embedded sieve plate is installed at the discharge port, and the embedded sieve plate is evenly provided with sieve holes, and a raw material collecting trough is provided below the embedded sieve plate, and the ceramic raw material with a sufficiently small particle size can pass through the sieve holes and fall into the raw material collecting trough, which can be automatically discharged, and is more convenient to use.

DETAILED DESCRIPTION

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-3As shown, the utility model is a ceramic raw material grinder, comprising a shell 1, a first motor 2, a driving shaft 3, a rotating arm 4, a connecting rod 5 and a grinding mechanism 6; a feed port 11 is provided on the top of the shell 1, the first motor 2 is fixed to the bottom of the shell 1, the driving shaft 3 extends into the shell 1 from the bottom of the shell 1, the first motor 2 drives the driving shaft 3 to rotate, a rotating arm 4 is provided on the top of the driving shaft 3, the bottom of the end of the rotating arm 4 is connected to the grinding mechanism 6 through the connecting rod 5, the grinding mechanism 6 comprises a bracket 61 and a grinding roller 62, the bracket 61 is fixed to the bottom of the connecting rod 5, the grinding roller 62 is installed on the bracket 61, and the grinding roller 62 is rotatable; the grinding roller 62 contacts with the bottom of the inner wall of the shell 1, and the bottom of the inner wall of the shell 1 is a grinding surface. The first motor 2 drives the driving shaft 3 to rotate, drives the rotating arm 4 to rotate, and causes the grinding roller 62 to rotate around the driving shaft 3. The grinding roller 62 rotates around its own axis due to friction, and crushes and grinds the ceramic raw materials. The contact between the grinding roller 62 and the bottom of the inner wall of the shell 1 is line contact, which has less resistance and is more energy-efficient. It will not block the input and removal of the ceramic raw materials, and the grinding roller 62 can be pushed at any time to leave space for convenient removal of the ceramic raw materials, which is more convenient to use.

[0019] Furthermore, it also includes a support roller 7, which is arranged at the top of the end of the rotating arm 4, and the support roller 7 abuts against the inner top wall of the housing 1. The ceramic raw material may lift the grinding roller 62 to make the rotating arm 4 bend upward, resulting in an increase in the gap between the grinding roller 62 and the bottom of the housing 1, resulting in poor grinding effect. The support roller 7 can be arranged to abut against the rotating arm 4 to prevent the grinding roller 62 from being lifted.

If it is higher than the bottom surface of the inner wall, it may interfere with the grinding mechanism 6. If it is lower than the bottom surface of the inner wall, a groove is formed, which may easily cause ceramic raw materials to accumulate and block the sieve holes.

[0022] Furthermore, a brush ring 31 is fixed at the bottom of the driving shaft 3. When the driving shaft 3 rotates, the brush ring 31 is driven to rotate, and the bristles on the brush ring 31 sweep the ceramic raw material toward the grinding mechanism 6.
