Abstract
Description
Technical Field
[0001] The invention relates to the technical field of ceramic production, in particular to an automatic grinding device for ceramic production. Background Art
[0002] The ceramic cup is a product that is processed through a series of processes. The processing will inevitably cause burrs or unevenness on the rim of the cup. Since the rim of the cup is where people's lips must touch when drinking water, the rim of the cup needs to be polished. At the same time, in the existing ceramic cup production, the bottom of the ceramic cup also needs to be polished.
[0003] In the existing grinding device, the rim and bottom of the ceramic cup need to be grinded separately, but another clamping device is also needed to clamp the cup body. Since the ceramic cup itself is relatively brittle, directly clamping the cup body may lead to over-clamping. In order to better maintain the temperature of the liquid in the cup, the rim of the existing ceramic cup is usually designed to be thicker to reduce heat loss, and the bottom of the ceramic cup is usually firmer, so it is better to clamp at both ends. However, clamping at both ends can easily affect the grinding of both ends of the cup, and in actual use, the vacuum cleaner is not effective in directly removing the grinding dust at some corners or dust stuck to the cup, which in turn affects subsequent processing.

DETAILED DESCRIPTION
[0015] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below with reference to specific diagrams. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.
[0016] See also Figure 1 - Fig. 9 The embodiment of the present invention provides a technical solution: an automatic grinding device for ceramic production, comprising a base 1 and a cylinder 2 fixed to the upper end of the base 1, dust covers 3 are provided on the opposite sides of the upper and lower ends of the base 1, and an air suction pump 4 is provided on one side of the dust cover 3 located on the base 1, and the opposite ends of the two dust covers 3 are fixed to motors 6, the upper motor 6 is fixed to the bottom end of the cylinder 2, the upper and lower motors 6 are fixed to the opposite ends to the connecting blocks 7, and the bottom end of the connecting block 7 is fixed to a rotating frame 51, and the rotating frame 51 is penetrated by air suction holes 8, and the air suction holes 8 are connected to the air suction pump 4, and also includes: The alternating clamping mechanism 5 is convenient for alternately clamping and polishing the mouth and bottom of the ceramic cup, and the alternating clamping mechanism 5 is arranged in the dust cover 3; The gas storage mechanism 9 can make the gas rush out in the reverse direction through the suction of the suction pump 4, thereby impacting impurities such as dust; The trigger mechanism 10 cooperates with the gas storage mechanism 9 to enable the gas sucked out by the suction pump 4 to produce two effects. The trigger mechanism 10 is arranged in the alternating clamping mechanism 5 .
[0017] Specifically, when the grinding head 52 is facing the cup, the suction of the suction pump 4 can make the bottom end of the grinding head 52 close to the cup mouth, thereby improving the grinding effect, and no spring is needed to prevent the spring from being insufficient in elasticity after long-term use; The grinding head 52 rotates to the other side, that is, after grinding, due to the suction force of the air pump 4, the linkage block 99 moves upward to pull the linkage frame 910 downward, so that the push plate 93 at the bottom of the linkage frame 910 sprays the gas between the bottom of the push plate 93 and the rotating frame 51 downward, which can spray away the grinding dust at the inner corners of the cup or the stubborn dust stuck on the cup, thereby improving the subsequent dust suction effect. In addition, this process does not require the elastic force of the spring to cause the gas to spray out, and after the gas is sprayed downward, the bottom end of the suction hole 8 is connected to the outside, so that the suction pump 4 can absorb the sprayed impurities through the suction hole 8; The suction of the air suction pump 4 produces two effects in different states, and the setting of the air storage mechanism 9 can further promote the dust suction effect of the air suction pump 4; It should be noted that the air pump 4 usually realizes its function through a specific rotation direction. If the air pump 4 is to be reversed, a special air pump 4 is required, which will undoubtedly increase the purchase cost of the air pump 4. Secondly, the reversal of most air pumps 4 will also significantly reduce the performance of the air pump 4 and consume more electricity. Therefore, the device does not allow the air pump 4 to reverse, and can also achieve spraying through the air pump 4, and does not require the setting of a spring to prevent spring fatigue.
[0018] In another embodiment provided by the present invention, the alternating clamping mechanism 5 includes a rotating frame 51, and slides 56 are horizontally slidably arranged at the opposite ends of the two rotating frames 51, an electric push rod 57 is connected between one end of the slide 56 and the rotating frame 51, a motor 55 is fixedly connected to the slide 56, a rotating shaft 58 is fixedly connected to the output end of the motor 55, a rotating plate 54 is fixedly connected to the outer wall of the rotating shaft 58, and an arc groove 53 is provided at one end of the rotating plate 54 away from the central axis of the rotating frame 51, a grinding head 52 is movably inserted into the bottom end of the rotating plate 54, a ventilation groove 510 is provided on the outer wall of the rotating shaft 58, one end of the ventilation groove 510 is connected to the slide groove where the grinding head 52 is located, and the other end of the ventilation groove 510 is connected to a hose 59, the hose 59 is tightly attached to one end of the rotating shaft 58, and the hose 59 is tightly attached to the outer wall of one end of the rotating shaft 58 and fixed in the rotating frame 51.
[0019] Specifically, by setting the alternating clamping mechanism 5, the grinding of the two ends of the cup can be maintained even when the two ends are clamped, and the grinding and clamping can be switched by one power source, which has a simple structure and lower cost.
[0020] In another embodiment provided by the present invention, the gas storage mechanism 9 includes a lifting chamber 91 opened in the rotating frame 51, and an upper plate 92 is slidably arranged in the lifting chamber 91, the lifting chamber 91 is connected to the suction pump 4, a push plate 93 is arranged on the lower side of the upper plate 92, and a circular groove is arranged on the lower side of the push plate 93 at the bottom end of the rotating frame 51, a semi-cylinder 94 is fixedly connected to the upper end of the upper plate 92, and the vertical side wall of the semi-cylinder 94 is in close contact with the rotating frame 51, and a slot 1 96 and a slot 2 97 are arranged in the semi-cylinder 94, and the slot 1 96 and the slot 2 97 are arranged in the semi-cylinder 94. A baffle 95 is horizontally slidably provided at the upper end of the second slot 97, a spring 912 is fixedly connected between one end of the baffle 95 and the semi-cylinder 94, a linkage block 99 and a linkage frame 910 are respectively slidably provided up and down in the slot 1 96 and the second slot 97, a pull rope 911 is connected between the bottom end of the linkage block 99 and the upper end of the linkage frame 910, a lifting block 98 is fixedly connected to one end of the linkage block 99, and the lifting block 98 is slidably provided in the rotating frame 51, a cavity is provided between the bottom end of the linkage block 99 and the upper plate 92, and this cavity is communicated with the hose 59.
[0021] Specifically, after polishing, the linkage block 99 moves upward to pull the linkage frame 910 downward, so that the push plate 93 at the bottom of the linkage frame 910 will spray the gas between the bottom of the push plate 93 and the rotating frame 51 downward, which can spray away the polishing dust at the inner corners of the cup or the stubborn dust stuck to the cup, thereby improving the subsequent dust collection effect, and this process does not require the elastic force of the spring to prompt the gas to spray out.
[0022] In another embodiment provided by the present invention, the trigger mechanism 10 includes an insertion strip 101 that is horizontally movably inserted into the rotating frame 51, and the insertion strip 101 is in conflict with the rotating plate 54. A pressure frame 105 is fixedly connected to the upper end of the insertion strip 101, and the other end of the pressure frame 105 is in conflict with the inclined surface on the baffle 95. A blocking plate 102 is slidably arranged at the bottom of the suction hole 8 in the rotating frame 51, and a spring 2 103 is fixedly connected between one end of the blocking plate 102 and the rotating frame 51. The blocking plate 102 blocks the suction hole 8, and a pull rope 2 104 is connected between the other end of the blocking plate 102 and the insertion strip 101.
[0023] Specifically, when the grinding head 52 is facing the cup, the air suction of the suction pump 4 can make the bottom end of the grinding head 52 close to the cup mouth, thereby improving the grinding effect, and there is no need to use a spring to prevent the spring from being insufficient after long-term use. After grinding, the bottom end of the suction hole 8 is connected to the outside, so that the suction pump 4 can suck away the sprayed impurities through the suction hole 8.
[0024] Working principle: Before use, the rotating plate 54 and the grinding head 52 can be moved by moving the electric push rod 57, so that different ceramic cups can be polished. When using the device, first place the ceramic cup on the rotating rack 51 at the bottom, place the protrusion at the bottom of the cup on the lower grinding head 52, and then start the cylinder 2 to move the dust cover 3 and the rotating rack 51 downward until the cup mouth can be located on the upper grinding head 52, and then start the lower motor 1 55 to make the lower rotating plate 54 face upward, and then the three rotating plates 54 on the lower side clamp the bottom of the cup through the arc groove 53, and then start the upper motor 2 6 to move the dust cover 3 and the rotating rack 51 downward through the upper grinding head 52. The grinding head 52 rotates to complete the grinding of the cup mouth. When the cup mouth is being ground, the air suction pump 4 is started, and the air suction pump 4 can suck the upper plate 92 upward, and at the same time can suck the linkage frame 910 upward, so that the linkage block 99 is pulled downward, and the lifting block 98 squeezes the gas in the lower cavity, so that the gas passes through the hose 59 and the ventilation groove 510 and enters the slide groove where the grinding head 52 is located. Therefore, the grinding head 52 is pressed downward, and the bottom end of the grinding head 52 can be pressed against the cup mouth. The squeezing force can be controlled by the air suction pump 4, and the pressure can be increased to improve the grinding effect, and there is no need to use a spring to prevent the spring from being insufficient in elasticity after long-term use. After the mouth of the cup is polished, the upper motor 55 is started, so that the upper rotating plate 54 faces downward to clamp the mouth of the cup. When the rotating plate 54 rotates, the rotating plate 54 will squeeze the insert 101 inward, so that the pressing frame 105 squeezes the baffle 95, and the baffle 95 moves toward the slot 1 96, so that the upper end of the slot 1 96 is connected with the lifting chamber 91, and the upper end of the slot 2 97 is no longer connected with the lifting chamber 91. Due to the suction force of the suction pump 4, the linkage block 99 can be moved upward, so that the volume of the inner cavity at the lower side of the linkage block 99 increases, thereby the grinding head 5 2 is sucked up quickly, thereby preventing the bottom end of the grinding head 52 from colliding with the cup mouth when rotating, and the upward movement of the linkage block 99 will pull the linkage frame 910 down, so that the push plate 93 at the bottom end of the linkage frame 910 will spray the gas between the bottom end of the push plate 93 and the rotating frame 51 downward, which can spray away the grinding dust at the inner corners of the cup or the stubborn dust stuck to the cup. After the spraying, the pull rope 104 is stretched straight, and the blocking plate 102 moves, so that the bottom end of the suction hole 8 is connected with the outside, so that the suction pump 4 can suck away the impurities sprayed away through the suction hole 8; Then start the motor 55 on the lower side. When starting the motor 55, reduce the suction force of the suction pump 4 so that the grinding head 52 has less force when it collides with the cup to prevent the cup from being squeezed. A rubber pad is provided on the lower side to prevent the cup from being damaged when the grinding head 52 on the lower side turns to the lower side and the cup falls downward with a small amplitude.
