Description

Technical Field

[0001] This utility model belongs to the technical field of ore processing equipment, and specifically relates to a polishing device for quartz stone processing. Background Technology

[0002] Artificial quartz stone, as a new type of building decoration material, is widely used in countertops, floors, and other fields due to its excellent physical properties and decorative effects. In the production process of quartz stone slabs, the surface polishing process is a crucial step that determines the product's appearance quality. Currently, the industry generally uses automated polishing equipment for continuous processing, employing multiple sets of grinding heads to progressively grind and polish the slab surface.

[0003] However, existing quartz polishing equipment has significant technical drawbacks in practical applications: traditional slab fixing devices mostly employ rigid clamping mechanisms, typically using multi-point clamping to prevent slab displacement during polishing. This fixing structure results in the area of ​​the slab covered by the clamps not making contact with the polishing head, creating a surface polishing blind zone of approximately 5-8%. Especially when processing large-sized slabs, the unpolished areas formed by the clamps require manual repositioning and repolishing, which not only significantly reduces production efficiency but also easily leads to color differences in subsequent polishing processes, resulting in a lower product qualification rate. Furthermore, the secondary dust pollution generated during the repeated positioning process exacerbates equipment wear and increases maintenance costs.

[0004] Although some existing technologies have attempted to use vacuum adsorption fixing devices, in practical applications, they have revealed problems with insufficient adsorption stability, especially when processing non-standard sized plates, which are prone to displacement and pose safety hazards.

[0005] Therefore, this utility model provides a polishing device for processing quartz stone. Utility Model Content

The fifth lead screw is installed at the top of the housing, the fifth motor is installed at the top of the housing, and the output end of the motor is connected to the end of the fifth lead screw away from the opening. The fifth slider is threadedly connected to the fifth lead screw. The fifth slider is symmetrically installed at both ends of the fifth lead screw.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Next, refer to Figures 1 to 3 The embodiments are described in detail to enable those skilled in the art to better understand the present invention:

[0026] A polishing device for quartz stone processing:

[0027] An opening is provided on one side of the housing 1. A push rod hinge on one side of the door panel 2 is rotatably mounted on the opening. Sound insulation material is filled inside the housing 1 and the door panel 2. During polishing, the opening can be closed through the door panel 2 to reduce noise generated during production. The first lead screw 7 is rotatably mounted on the bottom of the housing 1 via a bearing seat. The first motor 9 is installed inside the housing 1, and the output end of the first motor 9 is connected to the end of the first lead screw 7 away from the opening via a coupling. The first slider 8 is threadedly connected to the first lead screw 7. The first slider 7 is restricted from rotation by a baffle or slide groove. When the first motor 9 drives the first lead screw 7 to rotate, the first slider 8 slides along the axis of the first lead screw 7. The second lead screw 10 is rotatably mounted on the top of the housing 1. The second motor 12 is installed inside the housing 1, and the output end of the second motor 12 is connected to the end of the second lead screw 10 away from the opening via a coupling. The second slider 11 is threadedly connected to the second lead screw 10. The second slider 11 is restricted from rotation. When the second motor 12 drives the second lead screw 10 to rotate, the second slider 11 slides along the axis of the second lead screw 10.

[0028] Support plates 13 are mounted on both the first slider 8 and the second slider 11. An array of first rollers 61 is mounted on the support plates 13, supporting the sides of the quartz plate. A sixth lead screw 64 is mounted on the support plate 13 via an array of bearing seats. Sixth sliders 65 are symmetrically mounted at both ends of the sixth lead screw 64, and are threadedly connected to it. The sixth lead screw 64 is a bidirectional lead screw; therefore, when the operator rotates the sixth lead screw 64 with a wrench, the sixth sliders 65 will move closer or further apart to accommodate quartz plates of different thicknesses and ensure the quartz plate is centered. A support frame 63 is vertically mounted on the sixth sliders 65. A sliding groove is provided at the end of the support frame 63 furthest from the support plate 13. A telescopic rod 14 is slidably mounted within the sliding groove, and a spring is installed within the sliding groove, with its two ends elastically abutting against the bottom of the sliding groove and one end of the telescopic rod 14, respectively. A second roller 62 is mounted at the end of the telescopic rod 14 furthest from the spring. When adjusting the distance between the second rollers 62 on the same sixth lead screw 64, the operator can adjust the distance between the second rollers to be less than the thickness of the quartz plate. The spring force clamps the quartz plate, further increasing its fixation. Furthermore, the spring pushes the telescopic rod 14 to adaptively extend and retract, allowing the second rollers 62 to better fit the surface of the quartz plate. This prevents gaps from appearing during movement of the second rollers 62 on the quartz plate surface due to dimensional errors, thus avoiding damage. Moreover, when loading and unloading, the operator does not need to adjust the sixth lead screw 64 each time; by squeezing the spring, the quartz plate can be directly removed and loaded, improving work efficiency.

[0029] In another embodiment, the width adjustment unit can also be implemented using a telescopic drive device, such as a combination of a pneumatic cylinder, an electric push rod, and a cylinder in conjunction with a regulating valve to achieve linear transmission.

[0030] Rubber pads are fitted onto the first roller 61 and the second roller 62 to prevent damage to the surface of the quartz plate. The rubber pads deform under pressure, increasing the contact area with the quartz plate, thereby preventing excessive pressure at the contact points between the quartz plate and the first roller 61 and the second roller 62, which could lead to damage.

[0031] The bottom of the housing 1 has a mounting groove. The third lead screw 41 is mounted in the mounting groove via a bearing seat. The third motor 43 is mounted in the mounting groove via bolts, and the output end of the third motor 43 is connected to one end of the third lead screw 41 via a coupling. The third slider 42 is threadedly connected to the third lead screw 41, and the third slider 42 is restricted from rotation. When the third motor 43 drives the third lead screw 41 to rotate, the third slider 42 moves along the axis of the third lead screw 41. The fourth lead screw 44 is vertically mounted on the third slider 42 via a support housing and bolts. The fourth motor 46 is bolted to the end of the fourth lead screw 44 away from the third slider 42. The fourth slider 45 is threadedly connected to the fourth lead screw 44 via a coupling, and the fourth slider 45 is restricted from rotation. When the fourth motor 46 drives the fourth lead screw 44 to rotate, the fourth slider 45 moves along the axis of the fourth lead screw 44. One end of the first push rod 47 is horizontally mounted on the fourth slider 45 via bolts, and the grinding machine 3 is mounted on the output end of the first push rod 47. The third lead screw 41 is used to drive the grinding machine 3 to move horizontally, and the fourth lead screw 44 is used to drive the grinding machine 3 to move vertically, so that the grinding machine 3 can polish both sides of the quartz plate from all angles and avoid dead corners. The first push rod 47 is used to adjust the distance between the grinding machines 3 to accommodate quartz plates of different thicknesses.

[0032] The fifth lead screw 51 is mounted on the top of the housing 1 via a bearing seat. The fifth motor is bolted to the top of the housing 1, and its output end is connected to the end of the fifth lead screw 51 furthest from the opening via a coupling. The fifth slider is threadedly connected to the fifth lead screw 51, restricting its rotation. The fifth sliders are symmetrically mounted at both ends of the fifth lead screw 51. The fifth lead screw 51 is a bidirectional lead screw, so when the fifth motor drives the sixth lead screw 64 to rotate, the fifth sliders will move closer or further apart to accommodate quartz plates of different lengths and ensure that the quartz plates are centered. One end of the second push rod 52 is bolted vertically onto the slider. The output end of the second push rod 52 is bolted to the sixth motor 53, and one end of the baffle 54 is mounted on the output end of the sixth motor 53. The sixth motor 53 drives the baffle 54 to rotate, keeping the baffle 54 in a vertical or horizontal state, thereby achieving avoidance or limitation of the quartz plates. The operator can adjust the distance between the baffles 54 according to the length of the quartz plate. When the grinding machine 3 and the fixed support unit 6 move, the baffles 54 will hinder the movement of the quartz plate, thereby allowing the quartz plate to move relative to the other two, ensuring that the entire surface of the quartz plate is polished. The second push rod 52 allows the baffles 54 to adapt to quartz plates of different widths and can also avoid the grinding machine 3 when it approaches.

[0033] In another embodiment, contact sensors can be installed on the baffles 54. The system controls the fifth motor to start, causing the baffles 54 to move closer together. When the contact sensor on any baffle 54 is triggered, the baffle 54 continues to move and pushes the quartz plate. When the contact sensors on both baffles 54 are triggered, the fifth motor is turned off. After each polishing cycle, the fifth motor starts, driving the fifth slider to move to the two ends of the fifth lead screw 51.

[0034] All of the above motors are servo motors capable of forward and reverse rotation.

[0035] The spacing between the width adjustment units is greater than the diameter of the grinding block 31, thereby avoiding interference between the grinding block 31 and the support plate 13 and the second roller 62.

[0036] In summary, before using this device, open door panel 2, start the first motor 9 and the second motor 12, and move the first slider 8 and the second slider 11 to the position closest to the opening. At this time, half of the support plate 13 is outside the housing 1. The operator adjusts the sixth lead screw 64 with a wrench according to the thickness of the quartz plate, thereby adjusting the width between the second rollers 62. Then, the operator places the lower end of the quartz plate on the first roller 61 through the equipment and pushes the quartz plate forward until the midpoint of the quartz plate roughly coincides with the midpoint of the support plate 13. Then, the operator can control the first motor 9 to start. The first motor 9 reverses and drives the first slider 8 to move to the initial position in the middle of the housing 1. At this time, the grinding machine 3 is located between the two second rollers 62 but does not contact them. The operator adjusts the distance between the grinding machines according to the length of the quartz plate, and then starts the entire equipment. The position adjustment unit 4 drives the grinding machine 3 to move and polish the entire surface of the quartz plate. During the movement of the grinding machine 3, the first motor 9 and the second motor 12 start, driving the fixed support unit 6 to move synchronously with the grinding machine 3, thereby avoiding interference with the grinding machine 3. Furthermore, since there are multiple sets of second rollers 62 and the length of the support plate 13 is greater than that of the quartz plate, the fixed support unit 6 remains fixed to the quartz plate during movement, preventing the quartz plate from shaking or tipping over. Simultaneously, the baffles 54 at both ends of the quartz plate hinder its movement under friction, thus allowing relative movement between the quartz plate and the other two components, ensuring that the entire surface of the quartz plate is polished. After polishing, the first slider 8 and the second slider 11 are moved to the position closest to the opening to remove the quartz plate. Then, a new quartz plate is pushed into the fixed support unit 6. When processing quartz plates of the same size, there is no need to readjust the distance between the second rollers 62 and the baffles 54.
