Description

Technical Field

[0001] This utility model relates to the field of material conveying and automation equipment technology, and in particular to an automatic zinc borate feeder. Background Technology

[0002] In the production and processing of zinc borate, automatic feeding machines are one of the key pieces of equipment to ensure continuous and automated production. Zinc borate, as an important inorganic flame retardant additive, is widely used in industries such as plastics, rubber, and coatings. Its production process requires extremely high precision and stability in raw material delivery. Automatic feeding machines can automatically transport zinc borate from storage devices to production equipment, reducing manual intervention and providing a stable supply of raw materials for subsequent batching and mixing processes. This is a crucial link in improving production efficiency and ensuring product quality. Existing automatic zinc borate feeders typically employ either screw conveyors or belt conveyors. Screw conveyors use a motor to drive a rotating screw blade within a conveying pipe, using the thrust of the blade to push the zinc borate to a designated location. Belt conveyors rely on the continuous movement of the conveyor belt, using friction to move the zinc borate along the belt before a feeding mechanism completes the material transfer. These traditional structures primarily rely on mechanical transmission for material transport; their technical principle is based on the mechanical force pushing or bearing the material, adjusting the conveying volume by controlling factors such as motor speed. However, existing feeding machines are prone to inaccurate material feeding during actual operation. Because zinc borate material itself is prone to uneven particle size and variations in flowability, traditional conveying structures struggle to accurately control the amount of material fed each time. This leads to deviations between the actual proportion of zinc borate added during the batching process and the preset value, thus adversely affecting the quality stability of the final product. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an automatic zinc borate feeder, which aims to improve the problem that the inaccurate feeding amount of traditional feeders may lead to deviations in the zinc borate mixing ratio, thus affecting product quality.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic zinc borate feeder, comprising a support frame, a conveying pipe disposed above the support frame, a quantitative feeding component disposed above the support frame, an anti-blocking component disposed above the support frame, and a conveying component disposed above the support frame; The quantitative feeding assembly includes a second filter cylinder, which is positioned above a first support. A second support is fixedly connected to the upper surface of the first support, and a frame is fixedly connected to the inner wall of the second support. A turntable is rotatably connected to the inner wall of the frame, and the first filter cylinder is fixedly connected to the inner wall of the frame. The second filter cylinder is fixedly connected to the inner wall of the turntable. A first rotating shaft is fixedly connected to the lower surface of the turntable, and a baffle is rotatably connected to the outer wall of the first rotating shaft. A second support is fixedly connected to the upper surface of the first support, and a fixed column is fixedly connected to the outer wall of the second support. A third support is fixedly connected to the inner wall of the second support, and a second motor is fixedly connected to the upper surface of the third support. A turntable is fixedly connected to the output end of the second motor, and a scraper is attached to the upper surface of the turntable.

[0005] Furthermore, the anti-blocking component includes a guide post, which is disposed above the first bracket. A fixing plate is fixedly connected to the lower surface of the guide post, and a hopper is fixedly connected to the outer wall of the fixing plate. An air hole is opened on the outer wall of the guide post. An air pipe is fixedly connected to the lower surface of the guide post. A rotating shaft is rotatably connected to the inner wall of the air pipe. A nozzle is rotatably connected to the outer wall of the rotating shaft. A support is fixedly connected to the outer wall of the first bracket. An air pump is fixedly connected to the upper surface of the support. An air pipe is fixedly connected to the output end of the air pump. The outer wall of the air pipe is fixedly connected to the inner wall of the guide post.

[0006] Furthermore, the conveying assembly includes an auger rod, which is disposed above a support. A base is fixedly connected to the outer wall of the support. A motor is fixedly connected to the upper surface of the base. A transmission shaft is fixedly connected to the output end of the motor. An auger rod is rotatably connected to the inner wall of the conveying pipe. The transmission shaft is rotatably connected to the outer wall of the auger rod. A belt is disposed above the support. The outer walls of the transmission shaft and the transmission shaft are meshed with the belt and fixedly connected to the inner wall of the frame. The outer wall of the funnel cylinder is in close contact with the inner wall of the funnel cylinder.

[0007] Furthermore, the upper surface of the baffle plate is fitted and connected to the outer wall of the second inlet cylinder, and the outer wall of the second inlet cylinder is rotatably connected to the upper surface of the second support.

[0008] Furthermore, the guide post is disposed on the inner wall of the hopper, and the outer wall of the air pipe is fixedly connected to the inner wall of the hopper.

[0009] Furthermore, the second support is located below the turntable, and the outer wall of the second support is fixedly connected to the inner wall of the frame.

[0010] Furthermore, one end of the funnel is attached to the upper surface of the turntable.

[0011] This utility model has the following beneficial effects: In this invention, when the first funnel cylinder is in contact with each of the second funnel cylinders on the turntable, the zinc borate in the first funnel cylinder falls into the second funnel cylinder. During rotation, the baffle limits the zinc borate in the second funnel cylinder. When the rotation reaches the gap in the second support, the baffle releases its obstruction, allowing the zinc borate to flow out. Then, when the rotation reaches the fixed column, the baffle blocks again. This solves the problem that the traditional feeding machine may have inaccurate feeding, leading to deviations in the zinc borate mixing ratio and affecting product quality. It improves product quality, speeds up the production pace, increases overall production efficiency, reduces material waste, and lowers raw material costs.

[0012] In this invention, the guide column guides the zinc borate to fall into the discharge port, and the air holes on the guide column disperse the zinc borate. Then, the nozzle sprays air freely under the action of gas through the rotating shaft, dispersing the zinc borate remaining on the inner wall of the discharge port, preventing material blockage at the discharge port, ensuring continuous and stable conveying of zinc borate, thereby improving overall production efficiency and reducing material waste.

[0015] 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.

[0016] Reference Figure 1 - Figure 3 An embodiment of this utility model is provided: an automatic zinc borate feeder, including a support frame 1, a conveying pipe 2 arranged above the support frame 1, a quantitative feeding component arranged above the support frame 1, an anti-blocking component arranged above the support frame 1, and a conveying component arranged above the support frame 1. The quantitative feeding assembly includes a second funnel 16, which is positioned above a first support 1. A second support 10 is fixedly connected to the upper surface of the first support 1, providing support for the frame 13. The frame 13 is fixedly connected to the inner wall of the second support 10, and a turntable 15 is rotatably connected to the inner wall of the frame 13. A first funnel 14 is fixedly connected to the inner wall of the frame 13, and a second funnel 16 is fixedly connected to the inner wall of the turntable 15. When the turntable 15 rotates with the first funnel 14, the second funnel 16 comes into contact with the turntable 15. When the turntable rotates and the second funnel 16 comes into contact with the first funnel 14, zinc borate is quantitatively fed into the second funnel 16. A first rotating shaft 22 is fixedly connected to the lower surface of the turntable 15, and a baffle 21 is rotatably connected to the outer wall of the first rotating shaft 22. The baffle 21 blocks the feeding port of the second funnel 16 to prevent zinc borate from leaking out. A second support 11 is fixedly connected to the upper surface of the first support 1. The baffle 21 is guided. When the baffle 21 rotates to the notch of the support 2 11, the baffle 21 releases the obstruction of the discharge port of the filter cylinder 2 16 through the rotating shaft 1 22, allowing zinc borate to be quantitatively discharged into the hopper 12. The outer wall of the support 2 11 is fixedly connected to the fixing column 29, which limits the baffle 21, causing the baffle 21 that has released the filter cylinder 2 16 to return to its original position and block the discharge port of the filter cylinder 2 16 again, so that zinc borate can be quantitatively discharged, reducing zinc borate waste and lowering the cost of zinc borate. The inner wall of the support 2 11 is fixedly connected to the support 3 20, and the upper surface of the support 3 20 is fixedly connected to the motor 2 19. The output end of the motor 2 19 is fixedly connected to the turntable 15, and the upper surface of the turntable 15 is attached to the scraper 18. As the turntable 15 rotates, the scraper 18 scrapes the zinc borate that is missed on the turntable 15 into the filter cylinder 2 16, reducing the waste of zinc borate and the cost.

[0017] Specifically, motor 19 drives turntable 15 to rotate within frame 13. Simultaneously, turntable 15 drives four funnel cylinders 16 to rotate. During rotation, when funnel cylinder 14, which is in contact with turntable 15, comes into contact with funnel cylinder 16, zinc borate from funnel cylinder 14 enters funnel cylinder 16. Each baffle 21 at the discharge port of each funnel cylinder 16 then blocks the flow to prevent leakage. When the plate rotates to the notch of support 21, the baffle 21 rotates through the rotating shaft 22 to release its obstruction of the discharge port of the filter cylinder 26, allowing the zinc borate in the filter cylinder 26 to fall quantitatively into the hopper 12. When the baffle 21, which has released its obstruction, rotates to the fixed column 29, the fixed column 29 limits the baffle 21, causing the baffle 21 to rotate to the discharge port of the filter cylinder 26 and block it again. Then, the baffle 21 continues to be limited by the guide of support 21 until it rotates to the notch. Then, the zinc borate that is leaking on the turntable 15 is scraped into the filter cylinder 26 by the scraper 18 that is in contact with it during the rotation of the turntable 15, thus avoiding the waste of zinc borate.

[0018] Reference Figure 1 - Figure 6The anti-blocking component includes a guide post 23, which is positioned above the support frame 1. A fixing plate 24 is fixedly connected to the lower surface of the guide post 23. Four annularly arranged fixing plates 24 fix the guide post 23. A hopper 12 is fixedly connected to the outer wall of the fixing plate 24. Air holes 25 are provided on the outer wall of the guide post 23. The air holes 25 utilize the impact force of airflow to break up clumps and remove adhering zinc borate, preventing blockage of the discharge port of the hopper 12. An air pipe 26 is fixedly connected to the lower surface of the guide post 23. A rotating shaft 27 is rotatably connected to the inner wall of hopper 12. A nozzle 28 is rotatably connected to the outer wall of the rotating shaft 27. The nozzle 28 rotates freely through the rotating shaft 27 under the action of airflow, allowing the nozzle 28 to spray air in multiple directions. This disperses the zinc borate remaining on the inner wall of hopper 12 to the discharge port of hopper 12, avoiding waste of zinc borate, reducing costs, and preventing blockage. A support 4 is fixedly connected to the outer wall of bracket 1. An air pump 6 is fixedly connected to the upper surface of support 4. An air pipe 1 is fixedly connected to the output end of air pump 6. 7. The outer wall of the air pipe 17 is fixedly connected to the inner wall of the guide column 23. The conveying assembly includes an auger roller 3, which is positioned above the support 1. A support 4 is fixedly connected to the outer wall of the support 1. A motor 5 is fixedly connected to the upper surface of the support 4. A drive shaft 8 is fixedly connected to the output end of the motor 5. The auger roller 3 is rotatably connected to the inner wall of the conveying pipe 2. A drive shaft 7 is rotatably connected to the outer wall of the auger roller 3. A belt 9 is positioned above the support 1. The drive shaft 8 and the drive shaft 7 are meshed with the belt 9. The outer wall of scraper 18 is fixedly connected to the inner wall of frame 13. The outer wall of funnel 14 is fitted to the inner wall of funnel 2 16. The upper surface of baffle 21 is fitted to the outer wall of funnel 2 16. The outer wall of funnel 2 16 is rotatably connected to the upper surface of support 2 11. Guide column 23 is set on the inner wall of hopper 12. The outer wall of air pipe 17 is fixedly connected to the inner wall of hopper 12. Support 2 11 is set below turntable 15. The outer wall of support 2 11 is fixedly connected to the inner wall of frame 13. One end of funnel 14 is fitted to the upper surface of turntable 15. Specifically, a fixed amount of zinc borate falls onto the guide column 23 inside the hopper 12. The air holes 25 on the guide column 23 are connected to the air pump 6 and air pipe 17 to the airflow inside the guide column 23. This airflow breaks up any agglomerated zinc borate or removes any zinc borate adhering to the hopper 12 and the guide column 23, preventing blockage of the discharge port. The nozzle 28 rotates freely through the rotating shaft 27 under the action of the airflow, thereby dispersing the zinc borate remaining on the inner wall of the discharge port of the hopper 12 to the discharge port from multiple directions. This prevents blockage of the discharge port from causing equipment downtime, reduces the cost of zinc borate, and improves production efficiency.

[0019] Working principle: When using an automatic zinc borate feeder, to determine the required quantity of feed, motor 19 is first started. Motor 19 drives turntable 15 to rotate within frame 13. Turntable 15, in turn, drives four funnels 16 to rotate simultaneously. During rotation, when each funnel 16 comes into contact with funnel 14, zinc borate is quantitatively dropped onto the inner wall of each funnel 16. Four baffles 21 respectively limit the amount of zinc borate in the four funnels 16. During rotation, when the baffles 21 rotate to the notch near the top of the conveying pipe 2 on support 11, The baffle 21 is rotated by the rotating shaft 22 to move away from the discharge port of the second 16 of the filter cylinder, thereby releasing the zinc borate in the second 16 of the filter cylinder and allowing the zinc borate to fall quantitatively into the hopper 12. Then, when it rotates to the fixed column 29, the baffle 21 is blocked back to limit the discharge port of the second 16 of the filter cylinder. Then, it rotates along the support 21 to continue to limit the discharge port of the second 16 of the filter cylinder until it rotates to the notch. Then, the zinc borate left in other areas of the turntable 15 is scraped into the second 16 of the filter cylinder by the scraper 18 during the rotation of the turntable 15, preventing the zinc borate from remaining on the turntable 15. In addition, when anti-blocking is required, zinc borate is first metered into the hopper 12 and falls onto the guide column 23. Then, the air holes 25 on the guide column 23 disperse the zinc borate through the air pump 6, so that the zinc borate is not left on the guide column 23. Then, the nozzles 28 on the lower surface of the guide column 23 blow away the zinc borate remaining on the inner wall of the discharge port of the hopper 12. Then, the nozzles 28 rotate freely through the rotating shaft 27 under the action of the gas, thereby achieving multi-directional air jetting, and then achieving anti-blocking of the discharge port. Then, the zinc borate is conveyed in the conveying pipe 2 by the auger roller 3 and the motor 5.
