Description

Technical Field

[0001] This utility model belongs to the field of gemstone processing technology, specifically relating to a material fine grinding device with guide grooves. Background Technology

[0002] Gemstones refer to stones or minerals that, after being cut and polished, meet the requirements for jewelry setting. These are precious minerals with beautiful colors, high hardness, and unchanging properties under atmospheric and chemical influences. They can be used as instrument bearings, abrasives, and decorative items, among other things.

[0003] In the gemstone processing process, the rough stone is first sliced, then the slices are cut into strips, and the strips are further cut into granules. The resulting granules are rectangular. If they need to be further processed into instrument bearings or similar parts, the edges need to be coarsely and finely ground to transform the original rectangular cross-section into a cylindrical shape.

[0004] Chinese patent document with application number CN201720700192.6 discloses a dust-removing sapphire coarse and fine grinding integrated machine, including a grinding part and a water storage tank; a motor is arranged at the center of the bottom end of the grinding part; a first rotating shaft is arranged at the center of the upper end of the motor; a large gear is arranged at the center of the first rotating shaft; a support rod is vertically fixed to the left side of the bottom end of the grinding part; a second rotating shaft is arranged above the support rod; small gears are fixed to the upper and lower ends of the second rotating shaft.

[0005] Further research by the applicant revealed that the technical solution, which involves coarse grinding of the edges of rectangular gemstone materials, is not suitable for grinding large batches of cylindrical materials. In particular, fine grinding requires multiple grinding operations to change the grinding amount, resulting in low efficiency and making it unsuitable for processing batches of parts and materials of various specifications.

[0032] like Figure 1 - Figure 4 As shown, the present invention provides a material grinding equipment with guide grooves, including a frame 1, a first roller assembly 2, a second roller assembly 3, a power source 4, and a pushing assembly 6;

[0033] The first roller assembly 2 includes a first grinding rod 20;

[0034] The second roller assembly 3 has a second grinding rod 30 arranged parallel to the first grinding rod 20, and a grinding gap 31 for placing the gemstone material 9 is provided between the first grinding rod 20 and the second grinding rod 30.

[0035] The power source 4 is connected to the frame 1 and is used to force the first roller assembly 2 and / or the second roller assembly 3 to operate;

[0036] Guide grooves 5 are symmetrically arranged on both sides of the first grinding rod 20 and the second grinding rod 30, and the guide grooves 5 are collinear with the grinding gap 31.

[0037] The first rotating roller assembly 2 and the second rotating roller assembly 3 are used, and the guide groove 5, which is collinear with the grinding gap 31, is set on the outer side of both. The cylindrical material to be processed can move along the length direction of the guide groove 5 simultaneously under the action of the external push rod, and be polished one by one by the first grinding rod 20 and the second grinding rod 30. In this way, the gemstone material 9 does not need to stop moving, and can be polished within the length range of the first grinding rod 20 and the second grinding rod 30, and then moved out from the other end. It is suitable for mass processing of cylindrical gemstone material 9 and has high polishing efficiency.

[0038] The first roller assembly 2 and the second roller assembly 3 should also include bearings and bearing seats. A sliding plate (not shown in the figure) is connected to the upper end face of the frame 1 by a guide rail. The first roller assembly 2 or the second roller assembly 3 is connected to the sliding plate through the bearing seat. Under the action of external force, the first roller assembly 2 or the second roller assembly 3 can slide along the direction of the guide rail.

[0039] The pushing component 6 is located on the side of the second grinding rod 30 away from the first grinding rod 20 and is connected to the upper end of the frame 1;

[0040] At least one of the first roller assembly 2 and the second roller assembly 3 can move along the width direction of the grinding gap 31 under the action of the pushing assembly 6, so that the first grinding rod 20 and the second grinding rod 30 move closer to or further away from each other.

[0041] In this technical solution, a shifting component 6 is used to adjust the position of the first rotating roller assembly 2 and / or the second rotating roller assembly 3, thereby changing the size of the grinding gap 31 between the first grinding rod 20 and the second grinding rod 30 to meet the processing requirements of materials of various sizes. Simultaneously, this method allows for changing the grinding amount during material grinding, applying the material multiple times and progressively according to the grinding process requirements to meet the precision grinding process requirements. Of course, the shifting component 6 can also adopt other structural forms, such as a telescopic cylinder.

[0042] like Figure 4As shown, specifically, the pushing assembly 6 includes a base 70 connected to the upper end of the frame 1, a connecting plate 73 slidably connected to the upper end of the base 70, and a pusher 74 connected to the connecting plate 73. The pusher 74 is connected to the second roller assembly 3.

[0043] The second roller assembly 3 has push arms 76 disposed on both sides of the second grinding rod 30 and connected to the rotating shaft 300.

A screw mechanism 71 is disposed between the base 70 and the connecting plate 73, and a pair of slide rails are disposed on both sides of the screw mechanism 71. The slide rails have a dovetail tenon and mortise structure in cross-section. This arrangement makes the movement of the second grinding rod 30 smoother under the action of the connecting plate 73 and the push head 74.

[0044] A handle 710 or knob connected to the screw mechanism 71 is provided on the outside of the base 70. The upper connecting plate 73 and the push head 74 can be moved by manually turning it.

[0045] The front of the pusher head 74 is provided with a push plate 75 that is connected to the push arm 76.

[0046] Among them, the power source 4 drives the first roller assembly 2 to operate through the cooperation of the belt 40 and the pulley.

[0047] A spray assembly 8 is also provided on the upper part of the first roller assembly 2 and / or the second roller assembly 3. The function of the spray assembly 8 is to cool the material by spraying water and remove the powder from the grinding process.
