Description

Technical Field

[0001] This utility model relates to the field of quartz sand grinding technology, specifically a quartz sand grinding device with a coarseness adjustment structure. Background Technology

[0002] Quartz sand is quartz particles produced by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is an important industrial mineral raw material. Quartz sand grinding mills are currently the most adaptable, advanced, and efficient grinding equipment, with the narrowest grinding chamber, the smallest lever gap, and the most concentrated grinding energy. Combined with a high-performance cooling system and automatic control system, continuous material processing and continuous discharge can be achieved, greatly improving production efficiency. Among them, Chinese Patent No. CN202410925385.6 discloses a quartz sand grinding equipment, including a crushing component, a screening component installed at the end of the crushing component, and a grinding component installed at the end of the screening component. The crushing component is used to crush quartz sand, the screening component is used to screen the crushed quartz sand, and the grinding component is used to grind the screened quartz sand. The crushed quartz sand flows into the filter cylinder through the first discharge hole. The second motor drives the filter cylinder to rotate, filtering the quartz sand. Quartz sand that does not meet the standards will be retained inside the filter cylinder. The non-standard quartz sand inside the filter cylinder can be discharged into the guide plate through the pallet. The inclined guide plate discharges the non-standard quartz sand back into the installation box, thus fully crushing and processing the quartz sand and ensuring that the quartz sand is fully filtered.

[0003] Based on the above, the inventors have discovered the following problems: the above-mentioned device can fully crush and process quartz sand, so that the quartz sand can be fully filtered, but it cannot process quartz sand of different sizes, and its applicability is low. When it is necessary to process quartz sand of different sizes, the grinding components need to be replaced, which not only increases the cost but also increases labor consumption. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quartz sand grinding device with a coarseness adjustment structure, comprising a support base, a roller, and a transmission belt assembly. Both ends of the roller are provided with connecting rings, and bearings are mounted on the connecting rings. The bearings are connected to the support base. One end of the roller is provided with a conveying mechanism, and the upper end of the conveying mechanism has a feeding port. The end of the roller away from the conveying mechanism is provided with a toothed ring, and a motor is mounted on one side of the toothed ring. The output end of the motor is provided with a gear, which meshes with the toothed ring. A toothed disc is also meshed on the toothed ring, and a roller is connected to the toothed disc. The roller is mounted on the support base via another bearing. A grinding assembly is provided inside the roller. The grinding assembly includes a connecting shaft. One end of the connecting shaft passes through the connecting ring and is connected to the support base via a bearing. The portion of the connecting shaft located outside the roller is connected to the roller via the transmission belt assembly.

[0005] Furthermore, the grinding assembly includes a connecting shaft, a grinding arc plate, and a telescopic sleeve. The connecting shaft contains a bidirectional lead screw, which is connected to a second motor. A telescopic sleeve is located at the center below the connecting shaft and is movably connected to the bidirectional lead screw. A connecting rod is located at the lower end of the telescopic sleeve. Different threaded sections of the bidirectional lead screw are threadedly connected to movable seats, and a pair of connecting parts are movably connected to the movable seats. The other end of the connecting parts is connected to the connecting rod. A grinding arc plate is located at the lower end of the connecting rod. Scraping assemblies are located on both sides of the grinding arc plate, and baffles are located at both ends of the grinding arc plate.

[0006] Furthermore, the scraping assembly includes a connecting rod, which is disposed on the grinding arc plate. The connecting rod is movably connected to a connecting frame, and a spring is provided between the connecting frame and the connecting rod. One end of the spring is connected to the connecting rod, and the other end of the spring is connected to the connecting frame. The connecting frame is connected to a scraper, and the scraper is in contact with the inner wall of the roller.

[0007] Furthermore, the upper end of the roller is provided with a feeding port, and both sides of the non-support base of the roller are provided with receiving grooves.

[0008] Furthermore, the conveying mechanism is connected in a through-hole connection with the roller.

[0009] Furthermore, the transmission belt assembly includes a driving pulley, a driven pulley, and an annular belt. The driving pulley is located at one end of the roller, and the driven pulley is located at one end of the connecting shaft. The driving pulley and the driven pulley are connected by an annular belt.

[0010] Furthermore, the lower end of the second motor is supported by a support base, and the connecting ring and the connecting shaft are also connected by a bearing.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the quartz sand grinding equipment with a coarseness adjustment structure is reasonable and has the following advantages:

[0012] (1) With the cooperation of motor 2, double-acting screw, moving seat and connecting parts, the distance between the grinding arc plate and the inner wall of the drum can be adjusted, so that quartz sand products of different coarse and fine sizes can be processed according to requirements. Its core advantage is that the grinding degree of quartz sand can be adjusted according to the needs of different batches during the production process without stopping the machine or manual operation. Traditionally, this adjustment usually requires manual operation, which is not only inefficient, but may also have inconsistent adjustment results, increasing the error and time cost in the production process. In contrast, the automated adjustment system can significantly improve production efficiency and reduce manual intervention. Among them, with the cooperation of motor 1, gear, gear ring, gear plate, roller and transmission belt group, the drum and grinding arc plate can be moved in a relative misalignment. At this time, the quartz sand is ground back and forth in the drum. This method can effectively improve the grinding efficiency of quartz sand. Since the opposite movement of the drum and the grinding arc plate is driven by the same motor, the energy utilization of the system is more efficient and unnecessary energy waste is avoided.

[0013] (2) Through the design of spring and scraper, when adjusting the distance between the grinding arc plate and the inner wall of the drum, the scraper can always be in contact with the inner wall of the drum, ensuring that the quartz sand can be smoothly scraped into the feed port. This not only reduces the need for manual cleaning, but also improves the efficiency of material flow, so that the quartz sand can maintain a stable conveying speed during the processing, further improving production efficiency; and the side of the scraper is arc-shaped, which can reduce the friction between the scraper and the inner wall of the drum during the grinding operation, ensuring that the grinding work continues smoothly, and can maintain good performance after long-term work.

[0020] 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.

[0021] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0022] Example:

[0023] In this embodiment, a quartz sand grinding device with a coarseness adjustment structure includes a support base 9, a roller 3, and a transmission belt assembly. Both ends of the roller 3 are provided with connecting rings, and bearings are mounted on the connecting rings. The bearings are connected to the support base 9. One end of the roller 3 is provided with a conveying mechanism 2, and the upper end of the conveying mechanism 2 is provided with a feeding port 1. The end of the roller 3 away from the conveying mechanism 2 is provided with a toothed ring 12, and a motor 7 is provided on one side of the toothed ring 12. The output end of the motor 7 is provided with a gear 8, which meshes with the toothed ring 12. A toothed disc 11 also meshes with the toothed ring 12, and a roller is connected to the toothed disc 11. The roller is mounted on the support base 9 via another bearing. A grinding assembly is provided inside the roller 3. The grinding assembly includes a connecting shaft 16. One end of the connecting shaft 16 passes through the connecting ring and is connected to the support base 9 via a bearing. The portion of the connecting shaft 16 located outside the roller 3 is connected to the roller via the transmission belt assembly.

[0024] The aforementioned transmission mechanism 2 is an existing transmission device, such as... Figure 2 As shown, this will not be elaborated upon here;

[0025] By starting motor 7, gear 8 is driven to rotate forward, which causes gear ring 12 to rotate in the opposite direction, and then gear disc 11 to rotate forward. Under the action of roller, drive wheel 6 is driven to rotate forward, and then driven wheel 10 is driven to rotate forward under the action of annular belt 13, which causes connecting shaft 16 to rotate forward synchronously, thereby causing grinding arc plate 15 to rotate forward in drum 3. Meanwhile, the reverse rotation of gear ring 12 causes drum 3 to rotate in the opposite direction. Through the relative misalignment of drum 3 and grinding arc plate 15, comprehensive grinding of quartz sand can be performed.

[0026] The starting mechanism of the aforementioned motor 7 can be as follows: after the motor 7 starts in the forward direction and rotates the gear ring 12 by 45 degrees, it immediately starts in the reverse direction and rotates the gear ring 12 in the reverse direction by 45 degrees. This allows the quartz sand to be reciprocated and ground at the lower end of the drum 3, increasing the efficiency and comprehensiveness of the quartz sand grinding.

[0027] The grinding assembly includes a connecting shaft 16, a grinding arc plate 15, and a telescopic sleeve 22. A bidirectional lead screw 19 is installed inside the connecting shaft 16, and the bidirectional lead screw 19 is connected to a motor 14. The telescopic sleeve 22 is located at the center of the lower part of the connecting shaft 16 and is movably connected to the bidirectional lead screw 19. A connecting rod 21 is located at the lower end of the telescopic sleeve 22. Different threaded sections of the bidirectional lead screw 19 are threadedly connected to movable seats 23, and a pair of connecting parts 20 are movably connected to the movable seats 23. The other end of each connecting part 20 is connected to the connecting rod 21. A grinding arc plate 15 is located at the lower end of the connecting rod 21. Scraping assemblies are located on both sides of the grinding arc plate 15, and baffles 17 are located at both ends of the grinding arc plate 15.

[0028] By starting motor 14, the bidirectional lead screw 19 is driven to rotate, causing the moving seats 23 to move closer together on the bidirectional lead screw 19. With the cooperation of connecting piece 20, the connecting rod 21 is pushed to move closer to the inner wall of the drum 3, causing the grinding arc plate 15 to move in the same direction. Thus, by adjusting the distance between the grinding arc plate 15 and the inner wall of the drum 3, different coarse and fine sizes of quartz sand can be processed. The telescopic sleeve 22 limits the movement of the connecting rod 21, and the baffle 17 can prevent the quartz block from falling onto the upper end of the grinding arc plate 15, so that the quartz block can be ground evenly.

[0029] The scraping assembly includes a connecting rod 18, which is mounted on the grinding arc plate 15. A connecting frame 26 is movably connected to the connecting rod 18, and a spring 25 is provided between the connecting frame 26 and the connecting rod 18. One end of the spring 25 is connected to the connecting rod 18, and the other end of the spring 25 is connected to the connecting frame 26. A scraper 24 is connected to the connecting frame 26, and the scraper 24 is in contact with the inner wall of the roller 3.

[0030] By adjusting the distance between the grinding arc plate 15 and the inner wall of the drum 3, the scraper 24 can always be in contact with the inner wall of the drum 3. This allows the scraper 24 to always scrape the quartz sand into the feed port 5. The side of the scraper 24 is arc-shaped, which can reduce the friction between the scraper 24 and the inner wall of the drum 3 during the grinding operation, so that the grinding operation can proceed normally.

[0031] The roller 3 has a feeding port 5 at its upper end, and the roller 3 has a receiving groove 4 on both sides of its non-support seat 9.

[0032] After the quartz sand is ground, the motor 7 is started and rotated 90 degrees, so that the discharge port 5 is rotated from the top of the drum 3 to the side of the drum 3. At the same time, the scrapers 24 on both sides of the grinding arc plate 15 rotate in the opposite direction at the same angle, which can push the quartz sand to the position of the discharge port 5. Then the quartz sand falls from the discharge port 5 into the receiving trough 4, thus realizing the discharge operation of quartz sand.

[0033] The conveying mechanism 2 is connected to the roller 3.

[0034] The transmission belt assembly includes a driving pulley 6, a driven pulley 10, and an annular belt 13. The driving pulley 6 is located at one end of the roller, and the driven pulley 10 is located at one end of the connecting shaft 16. The driving pulley 6 and the driven pulley 10 are connected by the annular belt 13.

[0035] Through the above-mentioned transmission belt assembly design, the rotation of the toothed disc 11 can drive the connecting shaft 16 to rotate in the same direction, thereby driving the grinding arc plate 15 to rotate in the same direction. This makes the movement of the grinding arc plate 15 and the roller 3 relative to each other, thereby increasing the grinding efficiency of the quartz sand. Furthermore, the relative movement of the roller 3 and the grinding arc plate 15 is driven by the same power, reducing energy consumption.

[0036] The lower end of the motor 14 is supported by the support base 9, and the connecting ring and the connecting shaft 16 are also connected by a bearing;

[0037] The connection relationship between the above-mentioned motor 14 and the support base 9 is as follows: Figure 2 As shown.

[0038] Working principle: During use, quartz blocks are fed from the feed inlet 1 into the conveying mechanism 2, and then conveyed by the conveying mechanism 2 into the drum 3. The grinding components do not obstruct the movement of the quartz blocks into the drum 3. When the quartz blocks reach the bottom of the drum 3, the motor 14 is started, driving the bidirectional lead screw 19 to rotate. This causes the moving seats 23 to move closer together on the bidirectional lead screw 19. With the cooperation of the connecting piece 20, the connecting rod 21 is pushed closer to the inner wall of the drum 3, causing the grinding arc plate 15 to move in the same direction. Thus, by adjusting the distance between the grinding arc plate 15 and the inner wall of the drum 3, different coarse sizes of quartz sand can be processed. The telescopic sleeve 22 plays a role in the movement of the connecting rod 21. The limit function and the baffle 17 can prevent the quartz block from falling onto the upper end of the grinding arc plate 15, so that the quartz block can be fully ground. Then, the motor 7 is started, which drives the gear 8 to rotate in the forward direction, thereby causing the gear ring 12 to rotate in the reverse direction, and then the gear disk 11 to rotate in the forward direction. Under the action of the roller, the driving wheel 6 is driven to rotate in the forward direction. Then, under the action of the annular belt 13, the driven wheel 10 is driven to rotate in the forward direction, and the connecting shaft 16 also rotates synchronously in the forward direction, thereby causing the grinding arc plate 15 to rotate in the forward direction in the drum 3. The reverse rotation of the gear ring 12 causes the drum 3 to rotate in the reverse direction. Through the relative misalignment of the drum 3 and the grinding arc plate 15, the quartz sand can be fully ground.

[0039] Furthermore, after the motor 7 starts in the forward direction and rotates the gear ring 12 by 45 degrees, it immediately starts in the reverse direction and rotates the gear ring 12 by 45 degrees in the opposite direction. This allows the quartz sand to be reciprocated and ground at the lower end of the drum 3, increasing the efficiency and comprehensiveness of the quartz sand grinding. After the quartz sand is ground, the motor 7 is started and rotated 90 degrees, causing the discharge port 5 to rotate from the upper end of the drum 3 to the side of the drum 3. The scrapers 24 on both sides of the grinding arc plate 15 can push the quartz sand to the position of the discharge port 5, and then it falls from the discharge port 5 into the receiving trough 4, realizing the discharge operation of the quartz sand. Through the design of the spring 25, when adjusting the distance between the grinding arc plate 15 and the inner wall of the drum 3, the scraper 24 can always be in contact with the inner wall of the drum 3. This allows the scraper 24 to always scrape the quartz sand into the discharge port 5. The side of the scraper 24 is arc-shaped, which can reduce the friction between the scraper 24 and the inner wall of the drum 3 during the grinding operation.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
