Description

Technical Field

[0001] The invention relates to the technical field of luxury stone preparation, and in particular to an artificial quartz luxury stone and a preparation method thereof. Background Art

[0002] In the processing of artificial luxury stone, the raw materials (fine powder after grinding of stone) and auxiliary materials (special resin processing agent) are mixed and then pressed under high temperature and high pressure conditions. The special nature of luxury stone is created due to factors such as the non-fixed nature of its components, the internal characteristics of the raw materials, and the characteristics of the grain direction. Its essence can refer to the current preparation method of artificial stone, and specifically refer to the relevant content mentioned in the publication number CN114751716A.

[0003] The processes of adjusting patterns and laying materials / colors in the preparation process must be performed by experienced craftsmen, and the processes of batching, stirring and mixing mainly rely on mechanical control. However, it should be noted that the subsequent polishing and glazing are key steps in the overall processing process, and the process parameters of polishing and glazing are levelness, glaze thickness, glaze color, etc. The current polishing and glazing process still relies on experienced craftsmen to operate, and they judge the above process parameters based on their hand feel and their own experience. However, manual judgment cannot fully guarantee the overall polishing and glazing effect, especially because the degree of polishing and grinding leads to a lack of levelness on the stone surface, and subsequent problems such as uneven color distribution and glaze cross-flow will occur.

[0004] This application proposes a solution to this problem. Summary of the invention

[0005] The purpose of the present invention is to provide an artificial quartz luxury stone and a preparation method thereof, especially for the polishing and glazing process in the preparation process of artificial quartz luxury stone. Because the process relies on manual touch and personal experience to judge parameters such as levelness, glaze thickness, and glaze color, the judgment method is too single and cannot fully guarantee the overall polishing and glazing effect, and even causes related problems such as uneven thickness, uneven color distribution, and glaze cross-flow that affect product quality.

[0006] The purpose of the present invention can be achieved through the following technical solutions: a method for preparing an artificial quartz luxury stone, comprising four process steps of raw material mixing, pattern adjustment and material spreading, curing and polishing and glazing, wherein a luxury stone semi-finished product is obtained through the three process steps of raw material mixing, pattern adjustment and material spreading, and curing, and a grinding device is used in the polishing and glazing process step of the luxury stone semi-finished product, wherein the grinding device comprises a working frame, a flexible polishing belt, a working roller shaft and a main driving motor, and the flexible polishing belt is arranged in a mirror-symmetrical manner with the center line plane of the working frame along the horizontal direction;

[0007] The positions of the two flexible polishing belts close to each other in the vertical direction are set as a grinding area, and the positions of the two flexible polishing belts away from each other in the vertical direction are set as a buffer area. The grinding area in the flexible polishing belt is used to grind the luxury stone semi-finished product obtained in the curing process step;

[0008] The working frame is provided with an inner orientation frame and a compensation roller corresponding to the grinding area. The inner orientation frame is rotatably installed with a limiting roller at the inner position corresponding to the flexible polishing belt. The limiting roller and the compensation roller are located at the inner position of the flexible polishing belt.

[0009] It is further configured as follows: the working roller shaft is rotatably installed in the working frame in a direction parallel to the width of the flexible polishing belt, and the setting position of the working roller shaft corresponds to the two end positions of the flexible polishing belt, and the output shaft end of the main drive motor is fixedly connected to the center point of the working roller shaft.

[0010] It is further configured that: the two flexible polishing belts rotate in opposite directions through the working roller shaft and the main driving motor.

[0011] It is further configured as follows: the setting direction of the compensation roller and the limiting roller is parallel to the width direction of the flexible polishing belt, a sliding seat is provided on the inner wall position of the working frame corresponding to the inner orienting frame, the upper end position of the inner orienting frame is rotatably connected to the sliding seat, and an auxiliary drive motor corresponding to the inner orienting frame is installed on the sliding seat.

[0012] It is further configured as follows: an electric push rod is installed on the position of the sliding seat on the inner wall of the working frame, the sliding seat is slidably connected to the working frame along the length direction of the flexible polishing belt through the electric push rod, and a transverse adjustment groove corresponding to the sliding seat is opened on the working frame.

[0013] It is further configured that: a vertical adjustment slot is provided at a position of the working frame corresponding to the compensation roller, and the compensation roller is linearly and equidistantly arranged along the length direction of the flexible polishing belt;

[0014] Directional movable blocks are arranged at both ends of the compensation roller shaft. The directed movable blocks are slidably connected in the vertical adjustment groove along the vertical direction, and a vertically arranged inner sliding column is installed on the directed movable block. An air sleeve corresponding to the inner sliding column is installed on the working frame, and an air pipe is installed between each of the air sleeves.

[0015] It is further configured as follows: the inner sliding column on the directional movable block corresponding to the upper position is installed at the upper position of the directional movable block, and the inner sliding column on the directional movable block corresponding to the lower position is installed at the lower position of the directional movable block.

[0018] The present invention has the following beneficial effects:

[0019] 1. The overall device is aimed at the polishing process in the preparation of artificial luxury stone. Compared with the conventional polishing process, the overall process includes single-layer and double-layer polishing and grinding actions. Specifically, two synchronously rotating flexible polishing belts are used. The two flexible polishing belts move at a relative speed and in opposite directions of rotation, so that the two flexible polishing belts are used to apply two friction forces in opposite directions and with the same force to the artificial luxury stone. Compared with the conventional polishing process, a double-sided leveling grinding effect can be achieved;

[0020] 2. In combination with the above content, it is explained again that the overall process is to "wrap" the luxury stone semi-finished product with two flexible polishing belts, actively adjust the grinding area of ​​the luxury stone semi-finished product through the limit roller, and use pneumatic means to drive each compensation roller to provide opposite direction force to the luxury stone semi-finished product. Therefore, in the single-layer / double-layer polishing and grinding process, the polishing processes of the upper and lower surfaces of the luxury stone semi-finished product are interrelated and affect each other, which is used to improve the polishing level of the luxury stone.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0030] Embodiment 1:

[0031] Artificial luxury stone is prepared through processes such as batching, mixing, spreading / coloring, pressing, curing, and polishing. For the polishing process, because it relies on manual touch and experience to judge parameters such as levelness, glaze thickness, and glaze color, the judgment method is too single and cannot fully guarantee the overall polishing and glazing effect. There may even be problems such as uneven thickness, uneven color distribution, and glaze cross-flow that affect product quality. The following technical solutions are proposed:

[0032] Reference Figures 1 to 6 In this embodiment, a method for preparing an artificial quartz luxury stone comprises four process steps of raw material mixing, pattern adjustment and material spreading, curing and polishing and glazing. A luxury stone semi-finished product is obtained through the three process steps of raw material mixing, pattern adjustment and material spreading, and curing. A grinding device is used in the polishing and glazing process step of the luxury stone semi-finished product. The grinding device comprises a working frame 1, a flexible polishing belt 2, a working roller shaft 6 and a main driving motor 3. The flexible polishing belt 2 is arranged in a mirror-symmetrical manner with the center line plane of the working frame 1 along the horizontal direction;

[0033] The positions of the two flexible polishing belts 2 close to each other in the vertical direction are set as a grinding area, and the positions of the two flexible polishing belts 2 away from each other in the vertical direction are set as a buffer area. The grinding area in the flexible polishing belt 2 is used to grind the luxury stone semi-finished product obtained in the curing process step;

[0034] The working frame 1 is provided with an inner orienting frame 9 and a compensating roller 11 in the corresponding grinding area. The inner orienting frame 9 is rotatably installed with a limiting roller 10 on the inner side of the flexible polishing belt 2. The limiting roller 10 and the compensating roller 11 correspond to the inner side of the flexible polishing belt 2. The working roller 6 is rotatably installed in the working frame 1 in a direction parallel to the width of the flexible polishing belt 2, and the setting position of the working roller 6 corresponds to the two end positions of the flexible polishing belt 2. The output shaft end of the main drive motor 3 is fixedly connected to the center point of the working roller 6, and the two flexible polishing belts 2 rotate in opposite directions through the working roller 6 and the main drive motor 3.

[0035] Working principle: The polishing process in the preparation process of artificial luxury stone is improved. The similarity with the conventional polishing process is that the polishing belt is used to polish and grind the stone surface, but the difference is that the movement mode in the polishing process is improved and combined with Figure 2 and Figure 6 To illustrate, during the working process, the semi-finished luxury stone product to be processed is put into the middle position of the two flexible polishing belts 2, and the flexible polishing belts 2 are driven by the main driving motor 3 and the working roller shaft 6 to rotate synchronously. It should be noted that the rotation speeds of the two flexible polishing belts 2 are exactly the same, but the rotation directions of the two are opposite. Figure 6 For example, if the flexible polishing belt 2 at the upper position rotates counterclockwise, and then the flexible polishing belt 2 at the lower position rotates clockwise, its essence is: the flexible polishing belt 2 is used to synchronously polish and grind the surface of the luxury stone semi-finished product, and the upper position of the luxury stone semi-finished product is subjected to force in the right direction, while the lower position of the luxury stone semi-finished product is subjected to force in the left direction, and then on the basis of meeting the polishing requirements, it is used to maintain the position stability of the luxury stone semi-finished product.

[0036] Embodiment 2:

[0037] Further explanation on the polishing process of the semi-finished luxury stone products with two flexible polishing belts:

[0038] The setting direction of the compensation roller 11 and the limiting roller 10 is parallel to the width direction of the flexible polishing belt 2. A sliding seat 12 is arranged on the inner wall position of the working frame 1 corresponding to the inner orienting frame 9. The upper end position of the inner orienting frame 9 and the sliding seat 12 are rotationally connected. The sliding seat 12 is installed with an auxiliary driving motor 4 corresponding to the inner orienting frame 9. An electric push rod 13 is installed on the inner wall of the working frame 1 corresponding to the sliding seat 12. The sliding seat 12 is slidably connected on the working frame 1 along the length direction of the flexible polishing belt 2 through the electric push rod 13. The working frame 1 is provided with a transverse adjustment groove 7 corresponding to the sliding seat 12.

[0039] Because the sizes of artificial luxury stones are different, the specific polishing and grinding process is set up with the following action process:

[0040] S1: After the semi-finished luxury stone product to be processed is put in, the angle of the inner orientation frame 9 needs to be adjusted according to the length of the semi-finished luxury stone product. The specific essence is: the electric push rod 13 drives the sliding seat 12 to move left and right, and on this basis, the inner orientation frame 9 is further rotated by the auxiliary drive motor 4, so that the limiting roller 10 is completely in contact with the inner side of the flexible polishing belt 2. However, because the contact point position of the limiting roller 10 and the flexible polishing belt 2 is different, the length of the grinding area is changed, specifically, to ensure that the flexible polishing belt 2 corresponding to the grinding area is completely in contact with the semi-finished luxury stone product, which will not interfere with the rotation process of the flexible polishing belt 2, and the distance between the two flexible polishing belts 2 can also be further changed, so that the distance between the two is equal to the thickness of the semi-finished luxury stone product;

[0041] S2: In combination with S1, the air pipe 14 can also be inflated by a structure such as an air pump, wherein the inner sliding column 15 and the air sleeve 17 form a piston cylinder structure, thereby driving the directional movable block 16 at the upper side to move downward, and the directional movable block 16 at the lower side to move upward, so as to Figure 6 For example, the compensation roller 11 at the lower position provides an upward supporting force to the luxury stone semi-finished product, while the compensation roller 11 at the upper position provides a downward pressure to the luxury stone semi-finished product, and cooperates with the function of the limiting roller 10 to ensure that the flexible polishing belt 2 in the grinding area remains horizontal, avoiding the curvature of the flexible polishing belt 2 in this position and affecting the polishing effect.

[0042] Embodiment three:

[0043] Additional instructions for compensating rollers during polishing:

[0044] A vertical adjustment slot 8 is provided at a position of the working frame 1 corresponding to the compensation roller 11, and the compensation roller 11 is linearly and equidistantly arranged along the length direction of the flexible polishing belt 2;

[0045] Directional movable blocks 16 are arranged at both ends of the compensation roller shaft 11. The directional movable blocks 16 are slidably connected in the vertical direction in the vertical adjustment groove 8, and a vertically arranged inner sliding column 15 is installed on the directing movable block 16. An air sleeve 17 corresponding to the inner sliding column 15 is installed on the working frame 1, and an air pipe 14 is installed between each air sleeve 17. The inner sliding column 15 on the directing movable block 16 corresponding to the upper position is installed at the upper position of the directing movable block 16, and the inner sliding column 15 on the directing movable block 16 corresponding to the lower position is installed at the lower position of the directing movable block 16. A displacement sensor 5 corresponding to the directing movable block 16 is installed on the outer wall of the working frame 1, and the end of the transmission shaft of the displacement sensor 5 is connected to the directing movable block 16. The setting direction of the displacement sensor 5 is respectively set to the left end position, the middle section position and the right end position along the setting direction of the directing movable block 16.

[0046] In combination with the first and second embodiments, it is explained again that:

[0047] S3: Because the spacing between the two flexible polishing belts 2 is equal to the thickness of the semi-finished luxury stone product, and the compensation roller 11 only provides pressure and support, but there may be slight differences in the level of the surface of the semi-finished luxury stone product, so the compensation roller 11 can autonomously adapt to the level of the surface of the luxury stone. Because each air sleeve 17 is in a synchronous air supply state, when the surface of the luxury stone slowly tends to be completely horizontal, each directional block 16 drives the compensation roller 11 to completely approach the surface of the semi-finished luxury stone product. For this, it is necessary to add a displacement sensor 5 to detect the thickness of the semi-finished luxury stone product, and in order to improve the detection accuracy, refer to Figure 4 For example, each displacement sensor 5 is respectively arranged at the leftmost position, the rightmost position and the middle position relative to the setting direction of the vertical adjustment slot 8. When the detection values ​​of the displacement sensors 5 at the three positions are completely consistent, it means that the polishing process is slowly tending to be horizontal;

[0048] S4: It should be noted again that: because two flexible polishing belts 2 are provided in the present invention, the overall polishing process has two modes, single-layer and double-layer. Taking the single-layer mode as an example, the flexible polishing belt 2 in the upper or lower position has the ability to polish and grind the semi-finished luxury stone product, while the flexible polishing belt 2 in the other position does not have the ability to polish and grind, and only provides friction to maintain the position; in the double-layer mode, both flexible polishing belts 2 have the ability to polish and grind;

[0049] It should also be noted that: Figure 6 The buffer area shown in FIG. 1 is used as a processing structure of the flexible polishing belt 2 , for example, to clean and remove dust from the flexible polishing belt 2 in the buffer area.

[0050] In summary: For the polishing and glazing process of artificial quartz luxury stone, a flexible polishing and grinding method is adopted, which is essentially based on two flexible polishing belts. The overall process includes single-layer and double-layer polishing and grinding actions. Specifically, the luxury stone semi-finished product is completely "wrapped" by two flexible polishing belts, and the grinding area of ​​the luxury stone semi-finished product is actively adjusted by the limiting roller, and the compensation roller cooperates with the polishing and grinding process to perform an autonomous adjustment process. Compared with the conventional manual polishing method, the overall process can achieve a double-sided leveling grinding effect. The specific process is that the two flexible polishing belts exert friction in opposite directions on the luxury stone, and the grinding effects on both sides of the luxury stone semi-finished product are interrelated and affect each other, thereby ensuring the subsequent polishing and glazing effect of the luxury stone.
