Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic additive preparation technology, specifically relating to a weighable automatic feeding machine suitable for photovoltaic additive preparation. Background Technology

[0002] Photovoltaic additives refer to chemicals or auxiliary materials added to photovoltaic pastes, adhesives, coatings, and other materials during the production of photovoltaic materials. These additives play a role in improving material properties, increasing production efficiency, enhancing product quality, or optimizing processes during the manufacturing of photovoltaic products. When producing photovoltaic materials, photovoltaic additives need to be automatically added to the photovoltaic production process according to a predetermined ratio. Therefore, automatic feeding machines are one of the indispensable pieces of equipment in modern photovoltaic manufacturing.

[0003] An existing patent, CN216140920U, describes an automatic feeding machine. This patent includes a hopper and a conveyor. The hopper is surrounded by a weighing module and a vibration module. The weighing module includes a weighing sensor, and the vibration module includes a vibrator. The weighing sensor and vibrator are electrically connected to a PLC automatic controller, which is located within a control panel. The control panel has a display screen and control buttons, which are electrically connected to the PLC automatic controller. This device can achieve fully automatic weighing and metering of materials, which is more accurate than manual operation and operates in a fully sealed state, reducing dust pollution. However, in practical use, it still has the following shortcomings: Practically speaking, this device stores photovoltaic additive raw materials through the hopper, but lacks a stirring mechanism. The photovoltaic additive raw materials are prone to clumping or agglomeration due to static placement. The presence of clumping prevents the raw materials from flowing evenly, affecting subsequent feeding operations.

[0004] Therefore, there is a need for a weighable automatic feeding machine suitable for photovoltaic additives, which can solve the problem in the existing technology that photovoltaic additive raw materials are prone to clumping when left to stand, affecting subsequent feeding operations. Utility Model Content

[0005] The purpose of this invention is to provide a weighable automatic feeder suitable for photovoltaic additive preparation, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic weighing feeder suitable for photovoltaic additive preparation, comprising a frame, a plurality of support columns fixedly connected to the bottom of the frame, pulleys fixedly connected to the bottom of each of the support columns, a storage tank fixedly connected to the top of the frame, two conveying pipes fixedly connected to the top of the storage tank, two filter discs detachably connected to the top of each of the two conveying pipes, two feeding troughs detachably connected to the top of each of the two filter discs, a stirring mechanism provided inside the storage tank, a discharge pipe fixedly connected to the bottom of the storage tank, a switching valve installed inside the discharge pipe, a weighing sensor fixedly connected to the upper surface of the bottom of the frame, a weighing platform fixedly connected to the top of the weighing sensor, a cylinder fixedly connected to one side of the weighing platform, a pusher plate fixedly connected to the output end of the cylinder through one side of the weighing platform, a through groove corresponding to the weighing platform on the other side of the frame, and a hand-held push rod fixedly connected to one side of the frame.

[0007] It should be noted in the solution that all of the pulleys are universal self-locking wheels.

[0008] It is worth noting that the feed pipe is threadedly rotatably connected to the filter disc, and the filter disc is threadedly rotatably connected to the feed trough.

[0009] Furthermore, it should be noted that the stirring mechanism includes a servo motor fixedly connected to the center of the top of the storage tank. The output end of the servo motor passes through the top of the storage tank and is fixedly connected to a rotating shaft. Multiple sets of evenly distributed stirring blades are fixedly connected to the outer wall of the rotating shaft, and cleaning scrapers are fixedly connected to the outer ends of the multiple stirring blades.

[0010] In a preferred embodiment, the outer walls of the plurality of cleaning scrapers are all in contact with the inner wall of the storage tank.

[0011] In a preferred embodiment, the outer wall of the pusher plate is in contact with the inner wall of the weighing platform.

[0012] In a preferred embodiment, the outer wall of the push rod is fixedly connected with an anti-slip sleeve.

[0013] Compared with the prior art, the automatic weighing feeder provided by this utility model, suitable for the preparation of photovoltaic additives, has at least the following beneficial effects:

[0014] (1) By setting up a stirring mechanism and turning on the servo motor to drive the rotating shaft, multiple stirring blades can evenly disperse the photovoltaic additive raw materials inside the storage tank, preventing the photovoltaic additive raw materials from clumping due to standing, maintaining their fluidity and looseness, thereby ensuring the uniformity and accuracy of each feeding.

[0015] (2) By setting pulleys and hand push rods together, the device becomes more flexible, making it easier for staff to adjust the position, angle and operation status of the feeding machine according to actual needs, greatly reducing labor intensity and improving work efficiency.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a weighable automatic feeder suitable for photovoltaic additive preparation, including a frame 1, with multiple support columns 2 fixedly connected to the bottom of the frame 1, and pulleys 3 fixedly connected to the bottom of each support column 2. A storage tank 4 is fixedly connected to the top of the frame 1, and two conveying pipes 5 are fixedly connected to the top of the storage tank 4. Two filter discs 6 are detachably connected to the top of each of the two conveying pipes 5, and two feeding troughs 7 are detachably connected to the top of each of the two filter discs 6. A stirring mechanism 8 is provided inside the storage tank 4. A discharge pipe 9 is fixedly connected to the bottom of the storage tank 4, and a switch valve 10 is installed inside the discharge pipe 9. A weighing sensor 11 is fixedly connected to the upper surface of the bottom of the frame 1, and a weighing platform 12 is fixedly connected to the top of the weighing sensor 11. A cylinder 13 is fixedly connected to one side of the weighing platform 12, and a pusher plate 14 is fixedly connected to the output end of the cylinder 13 through one side of the weighing platform 12. A through groove 15 corresponding to the weighing platform 12 is opened on the other side of the frame 1, and a hand push rod 16 is fixedly connected to one side of the frame 1.

[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that all of the pulleys 3 are omnidirectional self-locking wheels. The omnidirectional self-locking wheels make the movement of the equipment smoother and more stable, reducing the need for the operator to push or pull the equipment. At the same time, the omnidirectional self-locking wheels have a self-locking function, which can lock the wheels after the equipment reaches the predetermined position to prevent the equipment from accidentally sliding or deviating. This can prevent the equipment from shifting during operation, ensure the stable operation of the feeder, and avoid errors or material waste.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the feed pipe 5 is threadedly connected to the filter disc 6, and the filter disc 6 is threadedly connected to the feeding trough 7. The threaded connection design allows the filter disc 6 and the feeding trough 7 to be easily disassembled and cleaned. The threaded connection design makes the assembly and disassembly process simpler and more efficient. By rotating the connecting parts, the filter disc 6 can be quickly connected or disconnected from the feed pipe 5 or the feeding trough 7, avoiding the complex processes and additional operations that may be brought about by traditional connection methods. This simplified assembly and disassembly method can improve production efficiency and reduce production line downtime.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the outer wall of the pusher plate 14 is in contact with the inner wall of the weighing platform 12, ensuring that the pusher plate 14 can push the photovoltaic additive raw materials on the weighing platform 12 so that they automatically fall into the next production line.

[0026] Further as Figure 1 As shown, it is worth noting that the outer wall of the hand push rod 16 is fixedly connected with an anti-slip sleeve. The anti-slip sleeve increases the friction of the hand push rod 16, thereby reducing the risk of the operator's hand slipping when pushing the equipment and improving the operational safety of the equipment. At the same time, the anti-slip sleeve is usually made of soft and durable materials, which can improve the tactile feel of the hand push rod 16 and make the operator's hand feel more comfortable during long-term operation.

[0027] As can be seen from the above working process, by setting pulley 3 and hand push rod 16 in combination, the device becomes more flexible, making it easier for workers to adjust the position, angle and operating status of the feeding machine according to actual needs, which greatly reduces labor intensity and improves work efficiency.

[0028] Further as Figure 4As shown, it is worth noting that the stirring mechanism 8 includes a servo motor 801 fixedly connected to the center of the top of the storage tank 4. The output end of the servo motor 801 passes through the top of the storage tank 4 and is fixedly connected to a rotating shaft 802. Multiple sets of evenly distributed stirring blades 803 are fixedly connected to the outer wall of the rotating shaft 802. Each of the multiple stirring blades 803 has a cleaning scraper 804 fixedly connected to its outer end. By setting up the stirring mechanism 8, the servo motor 801 is turned on to drive the rotating shaft 802 to rotate, so that the multiple stirring blades 803 evenly disperse the photovoltaic additive raw materials inside the storage tank 4, preventing the photovoltaic additive raw materials from clumping due to standing, maintaining their fluidity and looseness, thereby ensuring the uniformity and accuracy of each feeding.

[0029] Further as Figure 4 As shown, it is worth noting that the outer walls of multiple cleaning scrapers 804 are all in contact with the inner wall of the storage tank 4, so that the cleaning scrapers 804 can automatically remove material residues on the inner wall of the storage tank 4, avoid photovoltaic additive raw materials from adhering to the tank wall, reduce the risk of cross-contamination, and ensure the consistency of product quality between different batches.

[0030] This solution has the following working process: In actual use, push the hand lever 16 to move the device to the designated position, then the multiple pulleys 3 self-lock to keep the device stable, pour the photovoltaic additive raw material to be configured into the two feeding troughs 7, the filter disc 6 can filter impurities and foreign objects in the raw material, and the filtered photovoltaic additive raw material enters the storage tank 4 through the conveying pipe 5, then turn on the servo motor 801 to drive the rotating shaft 802 to rotate, so that the multiple stirring blades 803 evenly disperse the photovoltaic additive raw material in the storage tank 4. When feeding, turn on the switch. Valve 10 discharges photovoltaic additive raw materials from feed pipe 10. The raw materials fall onto weighing platform 12 for weighing. When the set weight is reached, switch valve 10 automatically closes, cylinder 13 automatically opens and drives pusher plate 14 to push photovoltaic additive raw materials on weighing platform 12, so that they automatically fall into the next production line. When the configuration work is completed and the inner wall of storage tank 4 needs to be cleaned, clean water is added to storage tank 4, servo motor 801 is turned on to drive stirring blade 803 to rotate, so that multiple cleaning scrapers 804 scrape and clean the residue on the tank wall.

[0031] In summary: By setting up the stirring mechanism 8 and turning on the servo motor 801 to drive the rotating shaft 802 to rotate, multiple stirring blades 803 can evenly disperse the photovoltaic additive raw materials inside the storage tank 4, preventing the photovoltaic additive raw materials from clumping due to standing, maintaining their fluidity and looseness, thereby ensuring the uniformity and accuracy of each feeding; by setting up pulleys 3 and hand push rods 16 in combination, the device becomes more flexible, allowing staff to adjust the position, angle and operating status of the feeding machine according to actual needs, greatly reducing labor intensity and improving work efficiency.
