Description

Technical Field

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

[0002] Artificial quartz stone is a high-grade building decoration material with high hardness, high toughness, high temperature resistance, and corrosion resistance. Its production process mainly includes three stages: raw material processing, slab production, and polishing. Raw material processing involves screening, washing, crushing, and grinding natural quartz ore into quartz sand and quartz powder. Slab production involves mixing the quartz powder with auxiliary materials, then pressing the powder into shape in a mold using a pressing device, and finally curing the slabs in a curing oven. Polishing involves cutting and surface treatment of the slabs, followed by final packaging.

[0003] In the process of mixing raw materials and auxiliary materials, existing artificial quartz stone cannot agitate the materials in every corner of the mixing chamber. As a result, it is easy to cause uneven mixing of raw materials and auxiliary materials. During vacuum vibration compression molding, cracks, board breakage, and gaps are likely to occur, which directly affects the performance of the board.

[0004] Therefore, this utility model provides a mixing device for artificial quartz stone raw materials. Utility Model Content

The support rods are arranged in a circumferential array at the bottom of the mixing drum. The top of the mixing drum has an opening, and the first cover plate is installed at the opening. One end of the feed pipe is connected to the side wall of the mixing drum. An air jet hole is opened on the inner side wall of the mixing drum. One end of the air inlet pipe is connected to the air jet hole, and the other end is connected to the air pump. The air jet hole is located directly below the feed pipe. The mixing mechanism is installed on the cover plate and is used to mix the raw materials. The side wall anti-sticking mechanism is installed inside the mixing drum to prevent the raw materials from adhering to the inner side wall of the mixing drum. A solenoid valve is installed at the bottom of the mixing drum, and one end of the discharge pipe is connected to the solenoid valve.

[0007] Preferably, the jet nozzle is a flared shape and the jet nozzle faces downwards at an angle.

The housing is mounted on the first cover plate, and the second cover plate is mounted on the top of the housing. A through hole is provided on the first cover plate. One end of the fixed shaft is fixedly mounted on the second cover plate. The sun gear is fixedly mounted on the fixed shaft. The middle part of the planetary carrier is rotatably mounted on the fixed shaft. The first planetary gear and the second planetary gear are rotatably mounted at both ends of the planetary carrier. The gear ring is fixedly mounted on the inner side wall of the housing. The first planetary gear and the second planetary gear mesh with the sun gear and the gear ring, respectively. The motor is vertically mounted on the second cover plate. The output end of the motor passes through the second cover plate and is located inside the housing. The drive gear is fixedly mounted on the output end of the motor and meshes with the gear ring. One end of the first rotating shaft is fixedly connected to the first planetary gear, and one end of the second rotating shaft is fixedly connected to the second planetary gear. Both the first rotating shaft and the second rotating shaft pass through the through hole and enter the stirring drum. Multiple stirring rods are evenly mounted on the first rotating shaft and the second rotating shaft.

[0009] Preferably, it also includes a dustproof plate, a sliding groove is provided on the side wall of the through hole, the dustproof plate is rotatably mounted on the sliding groove, and a clearance hole is provided on the dustproof plate for the first rotating shaft and the second rotating shaft to pass through.

[0010] Preferably, the clearance hole is in transition fit with the first rotating shaft and the second rotating shaft, and a sealing ring is installed in the clearance hole.

[0011] Preferably, the length of the stirring rod is greater than the distance between the axis of the first rotating shaft and the axis of the stirring drum, and the stirring rods on the first rotating shaft and the second rotating shaft are staggered along the axis of the stirring drum.

[0012] Preferably, the sidewall anti-sticking mechanism includes a support frame, a support shaft, and a scraper.

[0014] Compared with existing technologies, this utility model has the following beneficial effects:

[0015] 1. This utility model involves opening air jet holes on the inner wall of the mixing drum. When the raw material powder and auxiliary material powder enter the mixing drum from the feed pipe, the air pump is activated to input gas through the air inlet pipe and spray it out through the air jet hole. Since the air jet hole is located directly below the feed pipe, the material entering the mixing drum from the feed pipe will pass through the air jet hole, and the gas will evenly disperse the material, allowing the raw materials and auxiliary materials to be evenly mixed, thereby improving the uniformity of material mixing and the mixing effect of the mixing device.

[0016] 2. This utility model drives the first and second rotating shafts through a planetary gear mechanism, so that the first and second rotating shafts rotate around the axis of the mixing drum while also rotating on their own axis. Therefore, the stirring rod can stir the material in the central area of ​​the mixing drum towards the inner wall, and stir the material on the inner wall towards the central area. It can also stir any position in the mixing drum, further improving the uniformity of material mixing and the stirring effect of the stirring device.

[0017] 3. By rotatably connecting the support frame with the first and second rotating shafts, the support frame can rotate around the axis of the mixing drum when the motor starts. Therefore, the scraper on the support shaft can scrape off the material adhering to the inner wall of the mixing drum and allow it to participate in the mixing process. This avoids material waste and further improves the uniformity of material mixing and the mixing effect of the mixing device. Attached Figure Description

[0027] 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.

[0028] Next, refer to Figure 1 and Figure 6 The embodiments are described in detail to enable those skilled in the art to better understand the present invention:

[0029] A mixing device for artificial quartz stone raw materials, reference Figures 1 to 4 Support rod 2 is installed at the bottom of mixing drum 1 via a circumferential array of bolts to support mixing drum 1. An opening is provided at the top of mixing drum 1, and a first cover plate 3 is bolted to the opening. A sealing ring is used between the first cover plate 3 and mixing drum 1 to enhance the sealing effect. One end of the feed pipe 4 is connected to the side wall of mixing drum 1 and communicates with the interior of mixing drum 1, used to add raw materials and auxiliary materials into mixing drum 1. Multiple feed pipes 4 can be set according to actual needs. An air jet hole 10 is provided on the inner side wall of mixing drum 1. One end of the air inlet pipe 5 is connected to the air jet hole 10, and the other end is connected to an air pump. The air jet hole 10 is located directly below the feed pipe 4. When the raw material powder and auxiliary material powder enter the mixing drum 1 from the feed pipe 4, the air pump starts and inputs gas through the air inlet pipe 5 to the jet hole 10. Since the jet hole 10 is located directly below the feed pipe 4, the material entering the mixing drum 1 from the feed pipe 4 will pass through the jet hole 10. The gas will evenly disperse the material, allowing the raw materials and auxiliary materials to be mixed evenly, thereby improving the uniformity of the material mixing and the mixing effect of the mixing device.

[0030] The jet nozzle 10 is a funnel shape, which can increase the range of the raw materials and auxiliary materials being dispersed, and increase the uniformity of the mixing between them. The jet nozzle 10 is oriented at an angle downward, which can prevent the material entering the mixing drum 1 from the feed pipe 4 from falling into the jet nozzle 10 and causing blockage.

[0031] A solenoid valve 7 is bolted to the bottom of the mixing drum 1. One end of the discharge pipe 6 is connected to the solenoid valve 7. After the raw materials and auxiliary materials are mixed, the operator can activate the solenoid valve 7 to open it, allowing the mixed material to be discharged from the discharge pipe 6. An observation window is provided on the first cover plate 3. The observation window is fitted with a transparent material, such as glass or plastic, to facilitate the operator's observation of the internal condition of the mixing equipment.

[0032] Mixing mechanism reference Figures 3 to 6 The housing 813 is bolted to the first cover plate 3, and the second cover plate 812 is mounted on top of the housing 813. The first cover plate 3 has a through hole for the first rotating shaft 89 and the second rotating shaft 810 to enter the mixing drum 1. One end of the fixed shaft 83 is fixedly mounted to the second cover plate 812, and the sun gear 81 is welded to the fixed shaft 83, preventing it from rotating. The planetary carrier 85 is rotatably mounted on the fixed shaft 83 in the middle, and the first planetary gear 82 and the second planetary gear 84 are rotatably mounted at both ends of the planetary carrier 85. The gear ring 87 is fixedly mounted on the inner wall of the housing 813. The planetary gears mesh with the sun gear 81 and the gear ring 87 respectively, so the first planetary gear 82 and the second planetary gear 84 can rotate around the sun gear 81 while also rotating on their own axes. The motor 86 is vertically mounted on the second cover plate 812 by bolts. The output end of the motor 86 passes through the second cover plate 812 and is located inside the housing 813. The drive gear 88 is mounted on the output end of the motor 86 by a key connection and an elastic retaining ring. The drive gear 88 meshes with the gear ring 87. One end of the first rotating shaft 89 is fixedly connected to the first planetary gear 82, and one end of the second rotating shaft 810 is fixedly connected to the second planetary gear 84. Both the first rotating shaft 89 and the second rotating shaft 810 pass through the through hole and enter the stirring drum 1. Multiple stirring rods 811 are evenly mounted on the first rotating shaft 89 and the second rotating shaft 810.

[0033] When the motor 86 starts and drives the drive gear 88 to rotate, the drive gear 88 drives the gear ring 87 to rotate. The gear ring 87 drives the first planetary gear 82 and the second planetary gear 84 to rotate around the sun gear 81. The first planetary gear 82 and the second planetary gear 84 also rotate on their own axes. Therefore, the first rotating shaft 89 and the second rotating shaft 810 rotate synchronously with the first planetary gear 82 and the second planetary gear 84. Thus, the stirring rod 811 can stir the material in the central area of ​​the mixing drum 1 towards the inner wall, and stir the material on the inner wall towards the central area. It can also stir any position within the mixing drum 1, further improving the uniformity of material mixing and the stirring effect of the mixing device.

[0034] A sliding groove is formed on the side wall of the through hole, and a dustproof plate 814 is rotatably mounted on the sliding groove. The dustproof plate 814 has clearance holes for the passage of the first rotating shaft 89 and the second rotating shaft 810. The clearance holes are fitted with the first rotating shaft 89 and the second rotating shaft 810, and a sealing ring is installed inside the clearance holes. The dustproof plate 814 can prevent dust generated during the mixing of raw materials and auxiliary materials from entering the housing 813, thus avoiding affecting the stable operation of the gear transmission.

[0035] The length of the stirring rod 811 is greater than the distance between the axis of the first rotating shaft 89 and the axis of the mixing drum 1. Therefore, the rotation path of the stirring rod 811 will pass through the axis of the mixing drum 1, which better drives the material in the center of the mixing drum 1 towards the inner wall of the mixing drum 1. Since the stirring rods 811 on both the first rotating shaft 89 and the second rotating shaft 810 will pass through the axis of the mixing drum 1, the stirring rods 811 on the first rotating shaft 89 and the second rotating shaft 810 are staggered along the axis of the mixing drum 1. This avoids interference between the stirring rods 811 on the first rotating shaft 89 and the second rotating shaft 810, while increasing the stirring of different levels within the mixing drum 1, further enhancing the stirring effect.

[0036] Side wall anti-stick mechanism, see reference Figure 6 The support frame 91 is rotatably connected to both ends of the first rotating shaft 89 and the second rotating shaft 810, allowing the support frame 91 to rotate around the axis of the mixing drum 1 when the motor 86 starts. The support shafts 92 are vertically mounted on the support frame 91 and are arranged in a circular array on the support frame 91. Both ends of the support shafts 92 are rotatably connected to the support frame 91 via torsion springs. The width of the scraper 93 is greater than the distance between the support shaft 92 and the inner wall of the mixing drum 1. Therefore, under normal circumstances, the scraper 93 will adhere to the inner wall of the mixing drum 1 under the action of the torsion springs. When the support frame 91 rotates, the scraper 93 can scrape off the material adhering to the inner wall of the mixing drum 1, allowing it to participate in the mixing process. This avoids material waste and further improves the uniformity of material mixing and the mixing effect of the mixing device.

[0037] In summary, the usage process of this application is as follows: Color powder, resin, curing agent, coupling agent, quartz sand, and quartz powder are added to the mixer in the following order: first, quartz sand is added; second, resin (after adding color powder and mixing thoroughly) is added; and finally, quartz powder is added. Each addition must be thoroughly mixed before proceeding to the next step to ensure uniform bonding of all materials. Each time material is added, it enters the mixing drum 1 through the feed pipe 4. During material transfer, the air pump is running, and the material entering the mixing drum 1 is evenly dispersed within the drum 1 by the gas, where it is thoroughly mixed with the other auxiliary materials. When material transfer stops, the air pump is simultaneously shut off. The motor 86 starts synchronously during feeding, driving the drive gear 88 to rotate. The drive gear 88 drives the gear ring 87 to rotate, which in turn drives the first planetary gear 82 and the second planetary gear 84 to rotate around the sun gear 81. The first planetary gear 82 and the second planetary gear 84 also rotate on their own axes. Therefore, the first shaft 89 and the second shaft 810 rotate synchronously with the first planetary gear 82 and the second planetary gear 84. The stirring rod 811 agitates and mixes the materials inside the mixing drum 1. The support frame 91 rotates with the first shaft 89 and the second shaft 810. The scraper 93 scrapes off the material adhering to the inner wall of the mixing drum 1, allowing it to participate in the mixing process. After the raw materials and auxiliary materials are mixed, the motor 86 is turned off, and the operator can activate the solenoid valve 7 to open it, allowing the mixed material to be discharged from the discharge pipe 6.
