Description

Technical Field

[0001] The invention relates to the field of seal stone grinding, in particular to a dust-free seal stone grinding device. Background Art

[0002] Seals, also known as stamps, are stationery used to print on documents to indicate identification or signature. Traditional seals are made from stone. In the process of stone processing (seal carving), manual sandpaper or non-professional large-scale grinding machines are generally used. The problems with these two methods are:

[0003] Problems with manual polishing:

[0004] 1. It takes a lot of time and energy to grind the entire stamp with manual sandpaper;

[0005] 2. Uneven manual grinding can cause irreparable damage to the seal stone;

[0006] 3. Due to the hardness of the seal stone, it requires a lot of force to grind, but it is still difficult to grind the seal surface flat, and it increases the labor intensity of both hands;

[0007] 4. During the stamp grinding process, a large amount of stone chips and / or dust will be inhaled into the body, affecting health and causing pollution to the operating environment;

[0008] 5. The part that uses sandpaper for manual grinding is operated, but some of it is not used due to different points of application; thus, the sandpaper cannot be used to the maximum extent;

[0009] Problems with grinding with non-professional large grinders:

[0010] 1. Due to its large size, it needs to be placed in a specific place for use;

[0011] 2. Since it is not a professional seal stone grinding equipment, it is impossible to fix the seal stone;

[0012] 3. It is not a device for a specific purpose, so the corresponding functions are not used, resulting in increased costs;

[0013] 4. The overall size of the equipment is large, and the early operation process will be accompanied by large noise, which will affect the surrounding environment;

[0014] Then, in the prior art, although there is a printing bed tool; when engraving a stamp (seal), the stamp needs to be clamped for engraving, and the clamping tool uses a printing bed. The printing bed in the prior art is composed of a printing bed table, a push screw and a clamping plate arranged on the printing bed table; when using, according to the size of the engraved stamp, the number of clamping plates is selected, the stamp is placed between the clamping plates, and the push screw is turned to clamp the stamp at a diagonal position, and then the subsequent stamp engraving operation is carried out;

[0015] There are three common printing beds in the prior art:

[0016] 1. Rotatable printing bed: including a rotatable hardwood printing bed or a metal rotating printing bed, etc.

[0017] 2. Non-rotatable printing bed: including copper printing bed, bakelite printing bed, mahogany printing bed, etc.

[0018] 3. Portable printing bed: metal, wood and plastic.

[0019] The above three types of printing beds all rely on a pushing screw to tighten the seal in a diagonal position or use a wedge-shaped wood to squeeze the seal; and this method will have protruding parts on the basis of the original size of the printing bed, which will hinder the seal engraver and affect the seal engraving operation.

[0020] In summary, there is an urgent need for a device with a simple structure that can efficiently perform seal carving on seal stones without affecting the use of the seal carver. Summary of the invention

[0063] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] like Figure 1-4 As shown, the present invention provides a dust-free stone grinding device, comprising:

[0065] The clamping mechanism 1 is used to fix the seal stone; wherein the clamping mechanism 1 comprises:

[0066] The upper shell 11 and the adjustment group 12 movably arranged inside the upper shell 11; the upper shell 11 is connected to the grinding and collecting mechanism through a plurality of connecting columns 13; Figure 1 As shown, the adjustment group 12 is arranged in the upper shell 11 and can rotate in the upper shell 11; the clamping group 14 is arranged on the upper shell 11 and is adjusted in position under the drive of the adjustment group 12; that is, the position of the clamping group 14 is adjusted under the drive of the adjustment group 12, so as to fix the seal stone through the clamping group 14; and,

[0067] In the present invention, the adjustment group 12 includes a rotating gear 121 and a limit adjustment gear 122. The rotating gear 121 is movably arranged in a slot (not shown in the figure) inside the upper shell 11; the limit adjustment gear 122 is penetrated on the upper shell 11, one end of which is placed at the lower part of the rotating gear 121, and the other end is placed outside the upper shell 11; specifically, the other end of the limit adjustment gear 122 is protruding and arranged outside the upper shell 11. When operating, the other end of the limit adjustment gear 122 can be operated to make the limit adjustment gear 122 partially pulled The upper housing 11 is pulled out and the limit adjustment gear 122 is rotated. Since the limit adjustment gear 122 is meshed with the rotating gear 121, the rotating gear 121 is driven to rotate in the slot in the upper housing 11 while the limit adjustment gear 122 is rotated. Since the limit adjustment gear 122 is placed under the rotating gear 121, in addition to rotating the rotating gear 121 through the limit adjustment gear 122, the rotation of the rotating gear 121 itself can also be limited, that is, the movement of the rotating gear 121 is limited by the limit adjustment size.

[0068] Of course, in the present invention, the other end of the limit adjustment gear 122 can be always located outside the upper housing 11 and connected via a motor, so that when the rotating gear 121 needs to be adjusted, the limit adjustment gear 122 can be driven by the motor to rotate, and when the rotation stops, the rotation gear 121 is limited by the cooperation between the motor and the limit adjustment gear 122;

[0069] The clamping group 14 includes: a first telescopic fixing group 141 and a second telescopic fixing group 142. One end of the first telescopic fixing group 141 is arranged on the upper shell 11, and the other end is meshed with the rotating gear 121; one end of the second telescopic fixing group 142 is arranged on the upper shell 11 and is arranged diagonally with one end of the first telescopic fixing group 141, and the other end is meshed with the rotating gear 121; in this way, during the rotation of the rotating gear 121, the first telescopic fixing group 141 and the second telescopic fixing group 142 can be driven to move simultaneously, and then the seal stone is clamped by the first telescopic fixing group 141 and the second telescopic fixing group 142;

[0070] Moreover, the first telescopic fixing group 141 includes a telescopic fixing rod 1411 and a movable card slot 1412. One end of the telescopic fixing rod 1411 is fixed to the upper shell 11 by a bolt, and the other end is meshed with the rotating gear 121. Specifically, a card tooth (not shown in the figure) adapted to the rotating gear 121 is provided on the other end of the telescopic fixing rod 1411, so that when the rotating gear 121 rotates, the telescopic fixing rod 1411 can be driven to rotate with the bolt as the center. The movable card slot 1412 is penetrated on the telescopic fixing rod 1411; during the movement of the telescopic fixing rod 1411, the movable card slot 1412 is driven to move simultaneously.

[0071] In addition, in the present invention, the structure of the second telescopic fixing group 142 is the same as that of the first telescopic fixing group 141, and only in the process of connecting with the upper shell 11, the telescopic fixing rod 1411 is fixed diagonally by bolts, so that when the rotating gear 121 is actuated, the first telescopic fixing group 141 and the second telescopic fixing group 142 will respectively rotate with the bolt as the center of the circle, thereby realizing that the two movable card slots 1412 in the first telescopic fixing group 141 and the second telescopic fixing group 142 are gradually approached, so as to realize the blessing of the seal stone;

[0072] It should be noted that, in the present invention, the first telescopic fixing group 141 and the second telescopic fixing group 142 need to be arranged on the lower side of the rotating gear 121, so as to limit the position of the rotating gear 121, and when one end of the first telescopic fixing group 141 and the second telescopic fixing group 142 are connected by bolts, the bolt holes need to be arranged on the outer side of the card slot on the upper shell 11, so as to avoid affecting the movement of the rotating gear 121 after the bolts are inserted;

[0073] The grinding and collecting mechanism 2 is connected to the clamping mechanism 1; the clamping mechanism 1 is installed through the grinding and collecting mechanism 2, and the stone clamped by the clamping mechanism 1 is ground in cooperation with the clamping mechanism 1, and the stone chips and / or dust after grinding are collected; wherein,

[0074] The grinding and collecting mechanism 2 includes a lower shell 21, a collecting plate 22 and a grinding group 23. The lower shell 21 is connected to the clamping mechanism 1, supported by the lower shell 21, and performs stone chips and / or dust storage. Specifically, the clamping mechanism 1 is connected to the lower shell 21 through a plurality of connecting columns 13. A plurality of connecting holes (not shown in the figure) are provided on the upper shell 11. A plurality of connecting columns 13 are respectively passed through the connecting holes and then penetrated on the lower shell 21. The lower shell 21 is provided with mounting holes (not shown in the figure) adapted to the connecting columns 13. A plurality of connecting columns are penetrated in the mounting holes on the lower shell 21. In addition, it should be noted that the position of the connecting hole needs to satisfy the position of the card slot for installing the rotating gear 121, that is, the connecting hole is arranged on the periphery of the card slot on the upper shell 11.

[0075] The collecting plate 22 is disposed on the lower shell 21 and is connected to the lower shell 21 through the inlet 25; the grinding group 23 is disposed on the collecting plate 22; in the present invention, a collecting groove is disposed on the collecting plate 22, so that the stone chips and / or dust after grinding by the grinding group 23 will fall into the collecting groove; specifically,

[0076] The grinding group 23 includes a driving motor 231 and a grinding disc 233; the driving motor 231 is arranged on the collecting plate 22, and a fixing block 232 is arranged at one end of the output shaft; the grinding disc 233 is arranged on a fixing frame, and the fixing frame is penetrated on the fixing block 232; in actual use, the driving motor 231 drives the grinding disc 233 to rotate, thereby realizing the grinding of the seal stone;

[0077] like Figure 2 and 3 As shown, an L-shaped connecting shaft is provided between the output shaft of the driving motor 231 and the fixed block 232, so that after the fixed block 232 is connected through the L-shaped connecting shaft, the fixed block 232 is eccentrically arranged relative to the output shaft of the driving motor 231, thereby increasing the grinding range of the grinding disc 233; in the present invention, preferably, the grinding disc 233 is a diamond grinding disc or a flocking grinding disc;

[0078] It should be noted that, in the present invention, the diameter of the grinding disc 233 is smaller than the diameter of the collecting plate 22, so as to ensure that the stone chips and / or dust after grinding by the grinding disc 233 will fall into the collecting groove on the collecting plate 22 at the edge of the grinding disc 233; and because the fixing block 232 is eccentrically arranged, it is necessary to set the size of the L-shaped connecting shaft according to the size of the collecting plate 22, so as to avoid the grinding disc 233 from contacting the upper shell 11 during the rotation process, thereby limiting the rotation of the grinding disc 233; the specific size depends on the actual product, and the present invention will not further limit this;

[0079] In addition, in the present invention, the fixing frame includes a plurality of fixing arms 234, one end of the fixing arm 234 is connected to the fixing block 232, and the other end is connected to the grinding disc 233; thus, when the driving motor 231 is driven, the fixing frame will rotate simultaneously with the grinding disc 233;

[0080] Considering that the downward force of the grinding disc 233 and the fixing frame as a whole acts on the output shaft of the driving motor 231 during the rotation, in this case, long-term use may cause the output shaft to deform. Therefore, in the present invention, it is preferred to further provide a plurality of support arms 24, one end of which is provided on the collecting plate 22, and the other end is connected to the grinding disc 233; specifically, a slide groove (not shown in the figure) is provided at the other end of the support arm 24, and the grinding disc 233 is provided in the slide groove, so that on the one hand, the grinding disc 233 is supported by the slide groove, and on the other hand, the rotation of the grinding disc 233 driven by the driving motor 231 is not affected;

[0081] When the stone is continuously polished by the polishing disc 233, the stone chips and / or dust on the stone will fall from the edge of the polishing disc 233 into the collection slot on the collection plate 22. If the polishing is not cleaned for a long time, the collection slot will be filled with stone chips and / or dust. Therefore, in the present invention, a cleaning arm 26 is preferably provided. The cleaning arm 26 is connected to the output shaft of the driving motor 231 and rotates simultaneously with the output shaft. The cleaning arm 26 is used to sweep the stone chips and / or dust on the polishing disc 233 into the inlet 25, and pass through the lower shell 21 to be stored by the lower shell 21;

[0082] like Figure 3 As shown, a cleaning head is provided on the cleaning arm 26; when the output shaft of the driving motor 231 rotates, the cleaning arm 26 drives the cleaning head to rotate, and cleans the collecting groove on the collecting plate 22 through the cleaning head. When the cleaning position reaches the position of the inlet 25, the cleaned stone chips and / or dust pass through the inlet 25 into the lower shell 21.

[0083] In addition, in the present invention, since the upper shell 11 and the lower shell 21 are connected by a plurality of connecting columns 13, the upper shell 11 and the lower shell 21 can be separated as needed, and the upper shell 11 can be used alone to bless the seal stone, or the grinding and collecting device can be used alone to grind the seal stone, and then the use can be selected according to different stages of seal stone processing, making seal stone engraving more flexible.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
