Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to an automatic feeding device for a cotton cleaning machine. Background Technology

[0002] Opening and cleaning is the first step in cotton processing in cotton mills. It is also known as cotton cleaning and cleaning. Its purpose is to remove impurities such as fibrous fibers and foreign fibers from the raw cotton and produce cotton laps of qualified length and weight for the next step of carding. Cotton needs to be cleaned and cleaned during the processing. Since cotton is usually piled up together before being fed to the cleaning and cleaning machine, it is currently usually fed to the cleaning and cleaning machine manually by hand with forks or by centrifugal fans.

[0003] The existing centrifugal fan feeding mechanism requires manual movement of cotton to the centrifugal fan inlet. During the feeding process, the thickness of the cotton must be ensured. If the cotton is fed too thickly at once, it will cause jamming and poor cleaning effect. The existing centrifugal fan feeding mechanism relies entirely on the worker's skill to push the cotton to the centrifugal fan inlet. However, manual feeding usually involves a large amount of cotton, making it impossible to control the feeding amount. The existing feeding device cannot flexibly adjust the amount of cotton entering the cleaning machine according to the processing capacity of the cleaning machine. If not controlled, it will cause blockage of the inlet, affecting the normal use of the device, reducing work efficiency, and making it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding device for a cotton cleaning machine, which solves the above-mentioned technical problems, flexibly adjusts the feeding amount of the cotton cleaning machine, and is convenient for disassembly and cleaning.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic feeding device for a cotton cleaning machine, including a centrifugal fan, a square feed pipe at the air inlet of the centrifugal fan, a discharge pipe at the air outlet, and a dispersing component and a quantity control component arranged sequentially from right to left on the feed pipe.

[0006] The quantity control component includes an arc-shaped folding telescopic plate, which is located inside the feed pipe and is detachably connected to the feed pipe on the fixed side. Limiting blocks are threaded to the upper and lower ends of the movable side of the folding telescopic plate. Arc-shaped through grooves are provided at both the upper and lower ends of the feed pipe. When the limiting block is movably connected in the arc-shaped through groove and the bottom of the limiting block abuts against the arc-shaped through groove, the movable side of the folding telescopic plate is fixed. The convex surface of the folding telescopic plate is set close to the disintegration component.

[0007] By adopting the above technical solution, a dispersing component is set up to disperse the cotton sucked in by the centrifugal fan from the feed pipe. Before turning on the centrifugal fan to feed the cotton, the control component is adjusted. The adjustment process is as follows: Since the fixed side of the folding telescopic plate is restricted and fixed inside the feed pipe, and the upper and lower ends of the movable side are slidably connected inside the feed pipe, the distance between the fixed end and the movable end of the folding telescopic plate is adjustable. It is only necessary to rotate the limit block upward and then pull the movable end of the folding telescopic plate to make it slide in the arc-shaped groove. This realizes the adjustment of the feed channel part blocked by the folding telescopic plate, thereby adjusting the feed range in the feed pipe and thus achieving the purpose of controlling the feed amount of the cotton cleaning machine. After the adjustment is completed, the limit block is tightened downward to press and fix it in the arc-shaped groove, thereby limiting the movable side. This has the advantage of flexibly adjusting the feed amount of the cotton cleaning machine. The convex surface of the folding telescopic plate is a smooth plane and is set close to the dispersing component, which can prevent cotton from getting tangled on the folding telescopic plate and improve the feeding efficiency of the cotton cleaning machine.

[0008] A further feature of this invention is that the dispersing component includes a rotating shaft, with multiple dispersing plates evenly fixed to the end of the rotating shaft that passes vertically through the side wall of the feed pipe and is located inside the feed pipe, for dispersing cotton. It also includes a drive motor for driving the rotating shaft to rotate.

[0009] By adopting the above technical solution, a drive motor is set to drive the rotating shaft to rotate, thereby driving the dispersing plate to rotate. The dispersing plate disperses the cotton, avoiding blockage of the subsequent feed inlet and improving the smoothness and efficiency of feeding.

[0010] The present invention is further configured as follows: four dispersing plates are provided, the four dispersing plates are arranged in a cross shape, a cross-shaped through groove is opened on the side wall of the feed pipe for the dispersing plates to pass through, a cross-shaped sealing strip is provided in the through groove, and the rotating shaft is rotatably connected to the cross-shaped sealing strip.

[0011] By adopting the above technical solution and setting a cross-shaped through groove, during installation, the shaft is held and the cross-shaped dispersing plate is inserted into the feed pipe through the cross-shaped through groove. Then the shaft and drive motor are installed. Next, the cross-shaped sealing strip blocks the cross-shaped through groove, which facilitates the installation and disassembly of the dispersing plate. It has the advantages of convenient installation, disassembly and cleaning of the dispersing plate and the shaft.

[0012] A further feature of this invention is that it includes a fastening bolt. The upper and lower ends of the fixed side of the folding telescopic plate are respectively provided with threaded holes. The fastening bolt passes through the arc-shaped through groove and is threaded into the threaded hole to fix the fixed side of the folding telescopic plate.

[0013] By adopting the above technical solution, the fastening bolts are tightened into the threaded holes until they are pressed into the arc-shaped through groove. At this time, the fastening bolts are fixed, thereby fixing the folding telescopic plate and realizing the detachable connection between the folding telescopic plate and the feed pipe. When it is necessary to disassemble and clean the folding telescopic plate, simply unscrew the fastening bolts to release the limit on the fixed side, unscrew the limit block to release the limit on the moving end, and pull the folding telescopic plate out from the arc-shaped slide groove. This makes it convenient to clean and replace the folding telescopic plate.

[0014] A further feature of this invention is that a support rod is fixedly connected between the upper and lower limiting blocks, the support rod passes through the folding telescopic plate, and the upper and lower ends of the support rod are provided with external threads, with the limiting blocks threadedly connected to the support rod.

[0015] By adopting the above technical solution and setting a support rod, the threaded connection between the limiting block and the movable side of the folding telescopic plate is realized, which makes it easy to release the limiting block from the folding telescopic plate and makes the operation simple and convenient.

[0016] A further feature of this invention is that an arc-shaped sealing strip is provided inside the arc-shaped through groove.

[0017] By adopting the above technical solution, an arc-shaped sealing strip is set to block the arc-shaped through groove when the feeding device is working, so as to avoid air leakage affecting the feeding efficiency of the centrifugal fan.

[0018] A further feature of this invention is that the width of the arc-shaped through groove is greater than the width of the folding telescopic plate when it is fully folded.

[0019] By adopting the above technical solution, the folding telescopic plate is prevented from getting stuck in the arc-shaped through groove and thus cannot be folded, ensuring that the folding telescopic plate can be folded smoothly.

[0020] A further feature of this invention is that the top of the feed pipe, away from the centrifugal fan, is connected to a feed inlet, which is funnel-shaped.

[0021] By adopting the above technical solution, a funnel-shaped feed hopper is set up, which makes it convenient for manual labor or conveyor belts to feed cotton into the feed hopper.

[0022] A further feature of this invention is that a fixing plate is provided at one end of the feed pipe near the feed inlet for sealing the feed pipe, and a sealing ring is provided at the contact point between the fixing plate and the feed inlet.

[0023] By adopting the above technical solution, a sealing plate is set to block the feed pipe, and the sealing plate prevents air leakage, thus ensuring the suction efficiency of the centrifugal fan.

[0024] A further feature of this invention is that the quantity control component is provided in two sets, and the two sets of quantity control components are arranged symmetrically in front of and behind each other.

[0025] By adopting the above technical solution, two sets of material control components are set up, and a material passage is formed between the two movable sides of the folding telescopic plates, ensuring that the centrifugal fan always draws cotton evenly from the middle of the feed pipe and avoids clogging of the feed pipe.

[0026] The beneficial effects of this utility model are:

[0027] 1. Before turning on the centrifugal fan to feed material, this application first adjusts the quantity control component. Since the fixed side of the folding telescopic plate is restricted and fixed inside the feed pipe, and the upper and lower ends of the movable side are slidably connected inside the feed pipe, the distance between the fixed end and the movable end of the folding telescopic plate is adjustable. It is only necessary to rotate the limit block upward and then pull the movable end of the folding telescopic plate to make it slide in the arc-shaped through groove. This realizes the adjustment of the feed channel part blocked by the folding telescopic plate, thereby adjusting the feed range in the feed pipe and thus achieving the purpose of controlling the feed amount of the cleaning machine. After the adjustment is completed, the limit block is tightened downward to press and fix it in the arc-shaped through groove, thereby limiting the movable side. It has the advantage of flexibly adjusting the feed amount of the cleaning machine.

[0028] 2. In this application, the fastening bolts are tightened into the threaded holes of the folding telescopic plate until the fastening bolts are pressed into the arc-shaped through groove. This fixes the fastening bolts and thus the folding telescopic plate, enabling a detachable connection between the folding telescopic plate and the feed pipe. When the folding telescopic plate needs to be disassembled and cleaned, simply unscrew the fastening bolts to release the limit on the fixed side and unscrew the limit block to release the limit on the moving end, then pull the folding telescopic plate out of the arc-shaped slide groove. This facilitates cleaning and replacement of the folding telescopic plate. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] An example is an automatic feeding device for a cotton cleaning machine, such as... Figures 1-3 As shown, it includes a centrifugal fan 1, a square feed pipe 2 at the air inlet of the centrifugal fan 1, a discharge pipe 3 at the air outlet, and a dispersing component 4 and a volume control component 5 arranged sequentially from right to left on the feed pipe 2.

[0036] The quantity control component 5 includes an arc-shaped folding telescopic plate 50, which is located inside the feed pipe 2 and is detachably connected to the feed pipe 2 on its fixed side. The upper and lower ends of the movable side of the folding telescopic plate 50 are threadedly connected to limit blocks 51. The upper and lower ends of the feed pipe 2 are provided with arc-shaped through grooves 52. When the limit block 51 is movably connected in the arc-shaped through groove 52 and the bottom of the limit block 51 abuts against the arc-shaped through groove 52, the movable side of the folding telescopic plate 50 is fixed. The convex surface of the folding telescopic plate 50 is a smooth plane and is located close to the dispersing component 4. An arc-shaped sealing strip is provided in the arc-shaped through groove 52. The top of the feed pipe 2 away from the centrifugal fan 1 is connected to a horn-shaped feed inlet 8. A fixing plate 9 is provided at the end of the feed pipe 2 near the feed inlet 8 to block the feed pipe 2. A sealing ring is provided at the contact point between the fixing plate 9 and the feed inlet 8. The quantity control component 5 is provided in two sets, and the two sets of quantity control components 5 are symmetrically arranged front and back.

[0037] Specifically, such as Figure 1 , Figure 3 As shown, the cotton dispersing component 4 includes a rotating shaft 40, which passes vertically through the side wall of the feed pipe 2 and has multiple dispersing plates 41 evenly fixed on its end circumference inside the feed pipe 2 for dispersing cotton. It also includes a drive motor 42 for driving the rotating shaft 40 to rotate, dispersing cotton and preventing cotton blockage.

[0038] Specifically, such as Figure 1 , Figure 3As shown, there are four dispersing plates 41 arranged in a cross shape. The side wall of the feed pipe 2 is provided with a cross-shaped through groove 43 for the dispersing plates 41 to pass through. A cross-shaped sealing strip 44 is provided in the through groove. The rotating shaft 40 is rotatably connected to the cross-shaped sealing strip 44 to facilitate the disassembly and assembly of the dispersing plates 41.

[0039] Specifically, such as Figure 2 As shown, it also includes a fastening bolt 6. The upper and lower ends of the fixed side of the folding telescopic plate 50 are respectively provided with threaded holes. The fastening bolt 6 passes through the arc-shaped through groove 52 and is threaded into the threaded hole to fix the fixed side of the folding telescopic plate 50.

[0040] Specifically, such as Figure 2 As shown, a support rod 7 is fixedly connected between the upper and lower limit blocks 51. The support rod 7 passes through the folding telescopic plate 50. The upper and lower ends of the support rod 7 are provided with external threads.

[0041] Specifically, the width of the arc-shaped through groove 52 is greater than the width of the folding telescopic plate 50 when it is fully folded, so as to prevent the folding telescopic plate 50 from getting stuck when folded.

[0042] Its working principle is as follows: The discharge pipe 3 is connected to the feed inlet 8 of the cleaning machine to connect the cleaning machine with this feeding device. The folding telescopic plate 50 is inserted into the arc-shaped through groove 52, and the threaded fastening bolt 6 is threaded into the threaded hole on the fixed side of the folding telescopic plate 50 until the nut of the fastening bolt 6 is tightly abutted against the arc-shaped through groove 52, thus fixing the fixed side of the folding telescopic plate 50. Then, the movable end of the folding telescopic plate 50 is pulled to slide within the arc-shaped through groove 52, adjusting the shape between the movable sides of the two folding telescopic plates 50. Adjust the size of the material passage to a suitable position to control the feed amount of the cotton cleaning machine. After adjustment, tighten the limit block 51 downwards to connect the limit block 51 to the arc-shaped through groove 52, thereby limiting and fixing the movable side of the folding telescopic plate 50. This has the advantages of flexibly adjusting the feed amount of the cotton cleaning machine and improving feeding efficiency. Finally, turn on the centrifugal fan 1 to suck the cotton from the feed port 8 to the discharge port, turn on the drive motor 42 to drive the rotating shaft 40 to rotate, thereby driving the dispersing plate 41 to rotate, and the dispersing plate 41 disperses the cotton.
