Description

Technical Field

[0001] The utility model relates to the technical field of pearl grinding, in particular to a pearl grinding mechanism and a full-automatic pearl grinding device. Background Art

[0002] The existing pearl grinding equipment is a grinding wheel with upper and lower profiling molds. It uses a motor to drive the upper profiling mold to rotate, and at the same time uses the lever principle to apply a certain force to the upper profiling mold. The pearls are ground in the slide groove of the profiling mold. When the grinding time is certain, the pearls are taken out for measurement and classification.

[0003] However, this grinding equipment has the following defects:

[0004] 1) The surface smoothness of the pearls after grinding is inconsistent due to uncontrolled pressure during grinding;

[0005] 2) Currently, loading and unloading are done manually, and the pearls need to be laid flat manually, which is labor-intensive and inefficient.

[0006] 3) Grinding pearls of different sizes requires different grinding times, but these require experience, so not everyone can do it simply. The differences in experience and ability of personnel lead to differences in the roundness and smoothness of the ground pearls.

[0119] A plurality of second sliding elements 1022 are distributed in an array on the first bracket element 1021 .

[0140] With the mold element 1012 pressed against the pearl, the first support element 1021 continues to move downward;

[0141] The distance monitoring element 1032 monitors the distance between the first support element 1021 and the base element 1011. When the distance reaches a preset threshold, the distance monitoring element 1032 sends a signal to stop the external force and prevent the first support element 1021 from moving further downward.

[0142] The technical effects of the utility model are as follows:

[0143] The distance monitoring unit is used to monitor the distance between the first bracket unit and the grinding unit to prevent the first bracket unit from squeezing the grinding unit, thereby preventing the grinding unit from excessively squeezing the pearls and avoiding damage to the pearls.

[0144] Example 2

[0145] This embodiment is a variation of embodiment 1.

[0146] like Figure 5 As shown, the pearl grinding mechanism 1000 further includes a buffer unit 1040. The buffer unit 1040 is disposed between the grinding unit 1010 and the first bracket unit 1020, and is connected to the grinding unit 1010 and the first bracket unit 1020 respectively.

The buffer elements 1041 are distributed between the grinding unit 1010 and the first bracket unit 1020, and are respectively connected to the grinding unit 1010 and the first bracket unit 1020 for buffering.

[0148] Specifically, a plurality of buffer elements 1041 are distributed between the base element 1011 and the first bracket element 1021 , and are respectively sleeved with corresponding first sliding elements 1013 .

[0149] The buffer element 1041 has a ring-shaped structure.

Generally, the radial dimension of the inner edge surface of the buffer element 1041 is not smaller than the radial dimension of the first sliding element 1013, and the axial dimension of the buffer element 1041 is smaller than the axial dimension of the first sliding element 1013.

[0151] Generally, the axial dimension of the buffer element 1041 is smaller than the distance between the first support element 1021 and the base element 1011 .

[0152] The number of the buffer elements 1041 matches the number of the first sliding elements 1013. Generally, the number of the buffer elements 1041 is equal to the number of the first sliding elements 1013.

[0153] In some embodiments, the buffer element 1041 is a buffer structure, including but not limited to an elastic buffer sleeve.

[0154] The method of using this embodiment is as follows:

[0155] Under the action of external force, the base element 1011 moves downward along with the first bracket element 1021;

[0156] With the mold element 1012 pressed against the pearl, the first support element 1021 continues to move downward;

[0157] When the first support element 1021 contacts the buffer element 1041 , the buffer element 1041 buffers the downward force applied by the first support element 1021 .

[0158] The distance monitoring element 1032 monitors the distance between the first support element 1021 and the base element 1011. When the distance reaches a preset threshold, the distance monitoring element 1032 sends a signal to stop the external force and prevent the first support element 1021 from moving further downward.

[0159] The technical effects of this embodiment are as follows:

[0160] The buffer unit is used to buffer the force applied by the first bracket unit to the grinding unit, so as to prevent the first bracket unit from squeezing the grinding unit, thereby preventing the grinding unit from excessively squeezing the pearls and damaging the pearls; the buffer unit can maintain a certain pre-pressure to prevent damage to the pearls caused by excessive pressure.

[0228] In some embodiments, the third bracket unit 1110 is a fixed bracket.

[0229] The method of using this embodiment is as follows:

[0230] The mobile drive element 1084 operates, driving the first mobile element 1082 to rotate, thereby moving downward along the second mobile element 1083. This, in turn, drives the grinding drive unit 1050, the first bracket unit 1020, the distance monitoring unit 1030, the buffer unit 1040, the grinding unit 1010, and the constant pressure unit 1060 from the grinding waiting position to the grinding position via the second mounting element 1081 and the second bracket unit 1070. (Stable movement is achieved through the sliding cooperation of the fourth sliding element 1101 and the fifth sliding element 1102.)

[0231] After the first position monitoring element 1091 corresponds to the second position monitoring element 1092 in the grinding position, the moving driving element 1084 stops working; alternatively, the distance monitoring element 1032 monitors the distance between the first support element 1021 and the base element 1011. When the distance reaches a first preset threshold, the distance monitoring element 1032 sends a signal to the outside, and the moving driving element 1084 stops working.

[0232] The constant pressure unit 1060 works to control the contact pressure between the mold element 1012 and the upper part of the pearl to avoid crushing the pearl;

[0233] The grinding drive element 1052 rotates, driving the second transmission element 1053 to rotate, thereby driving the first transmission element 1051 to rotate through the third transmission element 1054, and further driving the first support element 1021 to rotate, thereby driving the mold element 1012 to rotate through the base element 1011 to perform the pearl grinding process;

[0234] After the pearl grinding process is completed, the grinding drive element 1052 stops working, and the moving drive element 1084 starts working, driving the first moving element 1082 to rotate, thereby moving upward along the second moving element 1083, and then driving the grinding drive unit 1050, the first bracket unit 1020, the distance monitoring unit 1030, the buffer unit 1040, the grinding unit 1010 and the constant pressure unit 1060 from the grinding position to the grinding waiting position through the second mounting element 1081 and the second bracket unit 1070; (stable movement is achieved under the sliding cooperation of the fourth sliding element 1101 and the fifth sliding element 1102);

[0235] After the first position monitoring element 1091 corresponds to the second position monitoring element 1092 in the grinding waiting position, the mobile driving element 1084 stops working; or, the distance monitoring element 1032 monitors the distance between the first bracket element 1021 and the base element 1011. When the distance reaches a second preset threshold, the distance monitoring element 1032 sends a signal to the outside and the mobile driving element 1084 stops working.

[0236] Repeat the above steps until all the pearls have been polished.

[0237] The technical effects of this embodiment are as follows:

[0238] The mobile unit is used to realize the automatic up and down shift of the grinding unit, which is convenient for the subsequent pearl collecting process.
