Description

Technical Field

[0001] This utility model relates to the field of quartz processing technology, specifically a quartz powder grinding mechanism. Background Technology

[0002] Quartz powder is made from natural quartz, whose main mineral component is SiO2. Quartz powder is a material produced by sorting, crushing, washing, purifying, drying, removing iron, grinding, and grading. Generally, products with a fineness of less than 120 mesh are called quartz sand, while products with a fineness of more than 120 mesh are called quartz powder. Quartz powder can be used to make glass.

[0003] A search of utility model publication CN220657812U reveals a quartz powder grinding mechanism. The grinding chamber contains an adjustment mechanism and a disassembly assembly. The adjustment mechanism includes a mounting plate fixedly installed between the left and right side walls of the grinding chamber's inner cavity. Two filter screens are fixedly installed inside the mounting plate. A motor is fixedly installed at the bottom of the mounting plate, and an electric push rod is fixedly installed on the motor's output shaft via a coupling. A grinding block is fixedly installed at the bottom of the electric push rod. A fixing plate is fixedly installed between the left and right side walls of the grinding chamber's inner cavity. A screening screen block with one end penetrating and extending to its bottom is movably installed on the top of the fixing plate. This quartz powder grinding mechanism, by incorporating the adjustment mechanism, achieves the goal of grinding quartz sand of different particle sizes, thereby expanding the grinding range and increasing grinding efficiency. This improves the applicability, practicality, and working efficiency of the quartz powder grinding mechanism.

[0004] The aforementioned grinding mechanism utilizes the relative movement of grinding blocks and screening screen blocks for grinding. The grinding distance is variable by connecting the grinding blocks with electric push rods, allowing for adjustments to the grinding of quartz powder of different mesh sizes. However, in actual use, the reaction force on the grinding blocks is borne by the electric push rods, leading to increasing axial offset and excessive stress on the bearing fixing positions. This can damage the equipment's self-locking structure and rapidly shorten its service life. Furthermore, the self-rotating grinding method of the grinding blocks results in a small grinding coverage area, with quartz concentrated on the periphery of the grinding blocks, leading to poor grinding performance. Therefore, this application designs a quartz powder grinding mechanism to address these shortcomings of the existing technology. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a quartz powder grinding mechanism, which has the advantages of replacing the electric push rod with a threaded locking structure to improve the axial stability of the grinding block connection, and improving the grinding coverage and grinding effect by using a crank to drive the grinding in combination with the locking structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quartz powder grinding mechanism, comprising a grinding disc built into a grinding box, a grinding block located in the grinding disc, three support legs, and a planetary disk mechanism connecting the support legs and the grinding block, wherein a first driving mechanism is provided at the bottom of the grinding disc for pulling the planetary disk mechanism to move;

[0007] The planetary disk mechanism includes a triangular disk, a guide tube fixedly installed above the triangular disk, and an extension tube integrally extending to the outside of the triangular disk.

[0008] The extension tube is provided with a height adjustment mechanism for controlling the extension distance of the grinding block toward the grinding disc. The height adjustment mechanism includes a threaded rod rotatably installed in the extension tube, a connecting handle connected to the threaded rod, and a vertical rod fixedly connected between the connecting handle and the grinding block.

[0009] One end of the connecting handle is fixed to the upper end of the upright, and a sliding sleeve is fixedly connected to the other end of the connecting handle. The sliding sleeve is slidably connected to the extension tube. An extension key is fixedly connected to the inner wall of the sliding sleeve, and a threaded sleeve is fixedly connected to the other end of the extension key. The threaded sleeve and the sliding sleeve are concentric circles, and the threaded sleeve and the threaded rod are threadedly connected to each other. A sliding groove is also provided through the outer wall of the extension tube, and the extension key is slidably connected to the sliding groove.

[0010] Compared to the method of grinding by rotating grinding blocks, the above technical solution has a wider coverage area, resulting in fewer quartz particles between the grinding block and the grinding disc, and thus a finer grinding finish.

[0011] As a preferred embodiment of this utility model, a bracket is fixedly installed at the bottom of the grinding disc;

[0012] The first drive mechanism includes a servo motor fixedly mounted on the bracket, a first pulley fixedly connected to the output end of the servo motor, a second pulley rotatably mounted on one of the support legs, and a transmission belt sleeved between the first pulley and the second pulley.

[0013] The above technical solution can control the planetary disk to perform circumferential trajectory grinding around the grinding disc.

[0014] As a preferred embodiment of this utility model, the triangular disk is composed of three extended legs corresponding to the support legs, extending from a circular frame corresponding to the size of the grinding disc. The grinding block is slidably connected to the guide tube and extends through to the outside of the guide tube.

[0015] As a preferred embodiment of this utility model, the three extension legs of the triangular disk and the three supporting legs have the same extension angle and are opposite to each other in pairs, and the corresponding supporting legs and the extension legs of the triangular disk are rotatably connected by cranks.

[0016] By adopting the above technical solution, the stability of the grinding block can be improved when the extension distance relative to the triangular disk is adjusted.

[0017] As a preferred technical solution of this utility model, a platform is integrally extended from the outer edge of the triangular disk, and a second drive mechanism for pulling the threaded rod is provided on the platform.

[0018] The second drive mechanism includes a first conical tooth fixedly connected to the lower end of the threaded rod, a support seat fixed to the platform, and a second conical tooth rotatably mounted on the support seat, wherein the first conical tooth and the second conical tooth mesh with each other.

[0019] The above technical solution allows users to easily adjust the traction grinding block to change the extension distance.

[0020] As a preferred embodiment of this utility model, the extension tube is hollow inside, and bearings are fixed at both ends of the extension tube, with the two ends of the threaded rod connected to the inner ring of the bearing.

[0021] By adopting the above technical solution, the rotational stability of the threaded rod inside the extension tube can be improved.

[0022] As a preferred embodiment of this utility model, a door panel can be installed in the middle of the grinding disc, and a locking device for locking the door panel is provided at the bottom of the grinding disc.

[0023] The above technical solution facilitates the unloading of quartz powder.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] This quartz powder grinding mechanism features a threaded rod and a threaded sleeve connected by threads. A sliding sleeve and a connecting handle are added to the outside of the threaded sleeve to extend and connect the grinding block. This design ensures good support stability of the grinding block after adjustment, and the self-locking structure of the threads further enhances structural stability. It also effectively mitigates axial deviation of the grinding block. In addition, three sets of support legs and cranks are used to pull the grinding block for oscillating grinding. This not only improves the frictional fineness of the contact between the grinding block and the quartz, but also reduces the force deviation of the grinding block in a single position, thus improving the practicality of the device.

[0032] 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.

[0033] Please see Figures 1 to 5 The quartz powder grinding mechanism in this embodiment includes a grinding disc 1 built into a grinding box, a grinding block 6 located in the grinding disc 1, three support legs 2, and a planetary disk mechanism connecting the support legs 2 and the grinding block 6. The planetary disk mechanism is used to pull the grinding block 6 to swing evenly along the exposed surface above the grinding disc 1.

[0034] In this application, a planetary disk mechanism is used to guide the grinding block 6 to move in a circular trajectory within the grinding disk 1 for grinding. Compared with the method of grinding by rotating the grinding block 6, it has a wider coverage area, so there is less quartz between the grinding block 6 and the grinding disk 1, and the grinding fineness is higher.

[0035] Furthermore, a first drive mechanism 7 is provided at the bottom of the grinding disc 1 for traction of the planetary disk mechanism. A bracket 102 is fixedly installed at the bottom of the grinding disc 1. The first drive mechanism 7 includes a servo motor 701 fixedly installed on the bracket 102, a first pulley 702 fixedly connected to the output end of the servo motor 701, a second pulley 703 rotatably installed on a support leg 2, and a transmission belt 704 sleeved between the first pulley 702 and the second pulley 703.

[0036] In this embodiment, the planetary disk mechanism includes a triangular disk 4, a guide tube 5 fixedly installed above the triangular disk 4, and an extension tube 8 integrally extending to the outside of the triangular disk 4. The triangular disk 4 is composed of three extension legs corresponding to the support legs 2 extending from a circular frame corresponding to the size of the grinding disk 1. The grinding block 6 is slidably connected to the guide tube 5 and extends through to the outside of the guide tube 5.

[0037] This design allows for better stability when the grinding block 6 is adjusted in terms of its extension distance relative to the triangular disk 4.

[0038] It should be noted that the upper end of the support leg 2 connected to the second pulley 703 is connected to the crank 3 via a pin. At the same time, the support leg 2 is fixed to the grinding disc 1 by a fixing bracket so that the crank 3 connected to it can be driven to rotate synchronously by the second pulley 703, which can also maintain the stability of the support leg 2.

[0039] Furthermore, the three extension legs of the triangular disc 4 and the three support legs 2 have the same extension angle and are opposite to each other in pairs. The corresponding support legs 2 and the extension legs of the triangular disc 4 are all rotatably connected by cranks 3.

[0040] This design allows the triangular disk 4 to be connected by three cranks 3, so that the triangular disk 4 and the grinding disc 1 form an eccentric circle, and the eccentric distance corresponds to the cranks 3, thereby achieving the traction of the circular swing trajectory of the grinding block 6.

[0041] In another embodiment, a friction strip 101 is also provided in the inner cavity of the grinding disc 1. The friction strip 101 is distributed along the spiral direction to increase the friction effect. At the same time, the thickness of the friction strip 101 should correspond to the grinding mesh of the quartz powder. In order to reduce the gap between the friction strip 101 and the inner cavity wall of the grinding disc 1, the friction strip 101 transitions to an arc shape between the inner cavity surface of the grinding disc 1.

[0042] In this embodiment, an adjustment mechanism is provided inside the extension tube 8 to control the extension distance of the grinding block 6 toward the grinding disc 1. The adjustment mechanism includes a threaded rod 801 rotatably installed inside the extension tube 8, a connecting handle 9 connected to the threaded rod 801, and a vertical rod 10 fixedly connected between the connecting handle 9 and the grinding block 6.

[0043] The extension tube 8 is hollow inside, and bearings are fixed at both ends of the extension tube 8. The two ends of the threaded rod 801 are connected to the inner ring of the bearings so that the threaded rod 801 can rotate inside the extension tube 8.

[0044] Furthermore, one end of the connecting handle 9 is fixed to the upper end of the upright 10, and a sliding sleeve 901 is fixedly connected to the other end of the connecting handle 9. The sliding sleeve 901 is slidably connected to the extension tube 8. Through the sliding connection of the sliding sleeve 901 relative to the extension tube 8, the position of the upright 10 can be easily changed by the connecting handle 9 relative to the extension tube 8, that is, the position of the grinding block 6 can be raised or lowered.

[0045] Furthermore, an extension key 902 is fixedly connected to the inner wall of the sliding sleeve 901, and a threaded sleeve 903 is fixedly connected to the other end of the extension key 902. The threaded sleeve 903 and the sliding sleeve 901 are concentric circles, and the threaded sleeve 903 and the threaded rod 801 are threadedly connected to each other.

[0046] In practical use, the threaded sleeve 903 can be moved relative to the threaded rod 801 by rotating the threaded rod 801.

[0047] In this embodiment, a groove 805 is also provided through the outer wall of the extension tube 8. The extension key 902 is slidably connected to the groove 805. By sliding the extension key 902 relative to the groove 805, the rotation of the threaded sleeve 903 can be restricted, thereby avoiding motion interference.

[0048] In order to rotate the threaded rod 801, a platform 401 is integrally extended from the outer edge of the triangular disk 4, and a second drive mechanism for traction of the threaded rod 801 is provided on the platform 401.

[0049] The second drive mechanism includes a first conical tooth 802 fixedly connected to the lower end of the threaded rod 801, a support seat 804 fixed on the platform 401, and a second conical tooth 803 rotatably mounted on the support seat 804. The first conical tooth 802 and the second conical tooth 803 mesh with each other, and the first conical tooth 802 can be rotated by rotating the second conical tooth 803, that is, the threaded rod 801 can be rotated.

[0050] To facilitate the unloading of quartz powder, a door panel 11 can be installed in the middle of the grinding disc 1, and a locking device is provided at the bottom of the grinding disc 1 for locking the door panel 11 when it is opened and closed.

[0051] The working principle of the above embodiment is as follows: by feeding the crushed quartz into the interior of the grinding disc 1, the servo motor 701 of the first drive mechanism 7 is controlled to run. When the servo motor 701 is running, it drives the first pulley 702 connected to its output end to rotate. The first pulley 702 pulls the second pulley 703 to rotate under the drive of the transmission belt 704.

[0052] Under the rotational traction of the second pulley 703, the crank 3 connected to the second pulley 703 drives the triangular disk 4 connected to the crank 3 to swing around the support leg 2 outside the grinding disk 1 in a circular trajectory. At this time, the grinding block 6 connected to the triangular disk 4 can realize swing grinding.

[0053] When it is necessary to change the extension distance of the grinding block 6, the second conical tooth 803 located on the outer platform 401 of the triangular disk 4 is rotated. The second conical tooth 803 rotates and drives the first conical tooth 802 to rotate by meshing with the tooth profile of the first conical tooth 802. Since the first conical tooth 802 and the threaded rod 801 are fixedly connected, the threaded rod 801 can rotate inside the extension tube 8.

[0054] When the threaded rod 801 rotates, it engages with the threaded sleeve 903, causing the threaded sleeve 903 to slide along the axial direction of the threaded rod 801. Since the upright rod 10 fixedly connected to the grinding block 6 and the connecting handle 9 outside the threaded sleeve 903 are fixedly connected, the grinding block 6 can slide relative to the guide tube 5 to change the distance that the grinding block 6 extends into the grinding disc 1.

[0055] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
