Description

Technical Field

[0001] This utility model relates to an automatic detection device for columnar desiccants, and more particularly to an automatic detection and feeding device for columnar desiccants. Background Technology

[0002] In industrial production, columnar desiccants are widely used in moisture-proof packaging for the food, pharmaceutical, and electronics industries. To ensure the quality and performance of the desiccant, its appearance integrity and dimensional specifications must be strictly inspected, and damaged or substandard products must be rejected.

[0003] A search revealed Chinese patent CN202420696731.3, which discloses an automatic detection and dispensing device for columnar desiccants. This patent features a first drive module that normally opens a blocking slide to ensure there is material in the feeding position. A first detection module detects the presence of material in the feeding position. Once material is present, subsequent desiccants accumulate in the preparation position. When a second detection module detects material in the preparation position, the second drive module compresses the desiccant there, blocking subsequent material. After the feeding mechanism delivers the bottle to its designated position, the first drive mechanism releases the desiccant from the feeding position, allowing it to slide into the positioned bottle. Simultaneously, the blockage in the preparation position ensures "one bottle, one desiccant." The first drive module then resets, and the second drive module releases the desiccant from the preparation position back into the feeding position, repeatedly limiting subsequent desiccant replenishment. This automatic detection and dispensing device replaces manual operation, improves production efficiency, and avoids problems such as over- or under-dispensing of desiccants and human-caused desiccant damage.

[0004] However, this device is mainly designed to detect damage or deformation of desiccants and cannot accurately screen the size specifications of desiccants. Some desiccant products that do not meet the size requirements may be mixed with qualified products, affecting subsequent packaging or use. In addition, the desiccant may cause detection errors due to accumulation or collision during transportation, further reducing the sorting accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic detection and feeding device for columnar desiccants, which has a screening function and can simultaneously detect appearance defects and sort by size and specifications of the desiccant, thereby improving sorting accuracy and production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic detection and feeding device for columnar desiccants is provided, including a screening chamber. A screening motor is installed on the outer wall of the screening chamber. A turntable is fixedly connected to the output end of the screening motor. A linkage column is provided on the outer wall of the turntable. A screening box is provided inside the screening chamber. Multiple through rods are fixedly connected to the outer wall of the screening box. A circular plate is fixedly connected to one end of each through rod. A spring is fixedly connected to the side of the circular plate facing the screening box. One end of the spring is fixedly connected to the outer wall of the screening box. A fixed plate is installed, and one end of the linkage column extends into the interior of the fixed plate. Positioning plates are fixedly connected to both outer walls of the screening box. Through grooves are opened on both outer walls of the screening chamber. Rollers are movably connected to the bottom of the inner wall of the through groove. The positioning plate passes through the through groove. Baffles are fixedly connected to both sides of the bottom of the screening box. A support plate is fixedly connected between the two baffles. An electric push rod is installed on the top of the support plate. A slider is fixedly connected to the top of the electric push rod. A flip plate is movably connected to the bottom of the screening box. A guide groove is opened at the bottom of the flip plate. The slider is located inside the guide groove. Optionally, the screening motor is located on the outer rear wall of the screening chamber, the turntable is located on the rear inner wall of the screening chamber, the through rod passes through the outer wall of the screening chamber, the guide groove is located between the two baffles, the front end of the guide groove is movably connected to the front bottom of the screening box via a hinge, and the guide groove has filter holes inside.

[0007] Optionally, the outer wall of the screening box is provided with a hollow groove, the hollow groove is located between the two through rods on the same side, a transparent acrylic plate is installed inside the hollow groove, and a camera assembly is installed on the outer wall of the screening chamber.

[0008] Optionally, a conveyor frame is fixedly connected to the bottom of the inner wall of the screening chamber, and a conveyor roller is movably connected to the inner wall of the conveyor frame. There are multiple conveyor rollers, and a conveyor belt is installed on the outside of the multiple conveyor rollers. A conveyor motor is installed on the outer wall of the conveyor frame, and the output end of the conveyor motor is fixedly connected to one end of the right-side conveyor roller.

[0009] Optionally, a collection box is installed inside the screening chamber, and the collection box is located at the front end of the conveyor.

[0010] Optionally, the top of the screening chamber is provided with a feed inlet, and the bottom of the screening chamber is fixedly connected with a support leg, and the number of support legs is multiple.

[0011] Optionally, the rear side of the inner wall of the screening box is inclined, and the filter holes are located at the front end of the guide groove and are evenly distributed.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model includes a screening motor, a turntable, a linkage column, a screening box, a through rod, a circular plate, springs, rollers, a baffle, a support plate, an electric push rod, and a slider. In use, material enters the screening box from the top through the feed inlet and falls onto the flip plate. Then, the screening motor runs, driving the turntable and linkage column to rotate synchronously. Because the linkage column is located inside the fixed plate connected to the rear end of the screening box, the springs cause the linkage column to move along the inside of the fixed plate during rotation, driving the fixed plate and the screening box to move back and forth. When the screening box moves to the right, the two springs on the right side are in a stretched state, while the two springs on the left side are in a compressed state; when the screening box moves to the left... The springs on both sides are in opposite states, and when the screening box moves left and right, the bottom of the positioning plates connected to both sides respectively engage with the corresponding rollers, reducing the resistance to the left and right movement of the screening box. This allows for the screening of desiccant particles inside the screening box. Smaller desiccant particles fall through the filter holes to the bottom, while desiccant particles that meet the size standard remain inside the screening box. After screening, the electric push rod retracts, and the slider at the top of the electric push rod descends simultaneously. Because the slider is located inside the guide groove at the bottom of the flip plate, the flip plate flips downwards with the front end as the center until the flip plate is tilted, and the granular desiccant slides down the flip plate. This utility model has a screening function, which can realize the simultaneous detection of desiccant appearance defects and size specification sorting, thereby improving sorting accuracy and production efficiency.

[0013] 2. This utility model is equipped with a camera component, a conveyor frame, a conveyor roller, a conveyor belt, and a conveyor motor. When the screening box moves back and forth, the amount of desiccant particles that meet the standard size will accumulate more and more. Through the acrylic glass set inside the hollow groove, the camera component can detect the accumulation height of the desiccant inside the screening box in real time, preventing the desiccant inside the screening box from overflowing due to excessive amount. When the desiccant reaches a certain height, the addition of granular desiccant to the feed inlet will stop. Attached Figure Description

[0021] Reference Figure 1-8 The present invention provides an automatic detection and feeding device for columnar desiccants. The device includes a screening chamber 1, a screening motor 2 mounted on the outer wall of the screening chamber 1, a turntable 3 fixedly connected to the output end of the screening motor 2, a linkage column 4 on the outer wall of the turntable 3, a screening box 5 inside the screening chamber 1, multiple through rods 6 fixedly connected to the outer wall of the screening box 5, a circular plate 7 fixedly connected to one end of each through rod 6, a spring 8 fixedly connected to the side of the circular plate 7 facing the screening box 5, one end of the spring 8 fixedly connected to the outer wall of the screening box 5, a fixing plate 9 mounted on the outer wall of the screening box 5, one end of the linkage column 4 extending into the interior of the fixing plate 9, positioning plates 10 fixedly connected to both outer walls of the screening box 5, and through grooves 11 formed on both outer walls of the screening chamber 1. The sieve box 5 is movably connected to a roller 12, and a positioning plate 10 passes through a through groove 11. Baffles 13 are fixedly connected to both sides of the bottom of the sieve box 5. A support plate 14 is fixedly connected between the two baffles 13. An electric push rod 15 is installed on the top of the support plate 14. A slider 16 is fixedly connected to the top of the electric push rod 15. A flip plate 17 is movably connected to the bottom of the sieve box 5. A guide groove 18 is opened at the bottom of the flip plate 17. The slider 16 is located inside the guide groove 18. The sieve motor 2 is located on the outer rear wall of the sieve chamber 1. The turntable 3 is located on the rear end of the inner wall of the sieve chamber 1. A through rod 6 passes through the outer wall of the sieve chamber 1. The guide groove 18 is located between the two baffles 13. The front end of the guide groove 18 is movably connected to the front bottom of the sieve box 5 through a hinge. Filter holes are opened inside the guide groove 18.

[0022] Material enters from the top of the screening box 5 through the feed inlet 26 and falls onto the flip plate 17. Then, the screening motor 2 runs, driving the turntable 3 and the linkage column 4 to rotate synchronously. Since the linkage column 4 is located inside the fixed plate 9 connected to the rear end of the screening box 5, the spring 8 moves along the inside of the fixed plate 9 during rotation, causing the fixed plate 9 and the screening box 5 to move back and forth. When the screening box 5 moves to the right, the two springs 8 on the right side are in a stretched state, while the two springs 8 on the left side are in a compressed state. When the screening box 5 moves to the left, the springs 8 on both sides are in the opposite state. And when the screening box 5 moves left and right, the fixed plate 3 connected to the left and right sides... The bottom of the plate 10 is in contact with the corresponding roller 12, reducing the resistance to the left and right movement of the screening box 5. This allows for the screening of desiccant particles inside the screening box 5. Smaller desiccant particles fall through the filter holes to the bottom, while standard-sized desiccant particles remain inside the screening box 5. After screening, the electric push rod 15 retracts, and the slider 16 at the top of the electric push rod 15 descends simultaneously. Since the slider 16 is located inside the guide groove 18 at the bottom of the flip plate 17, the flip plate 17 flips downwards with its front end as the center until it is tilted. The granular desiccant then slides down the flip plate 17. This invention has a screening function, enabling simultaneous detection of desiccant appearance defects and size sorting, thereby improving sorting accuracy and production efficiency.

[0023] In another embodiment of this utility model, please refer to Figures 1 to 3 The outer wall of the screening box 5 has a perforated groove 19, which is located between two through rods 6 on the same side. A transparent acrylic plate is installed inside the perforated groove 19. A camera component 20 is installed on the outer wall of the screening chamber 1. When the screening box 5 moves back and forth, the amount of desiccant particles that meet the standard size will accumulate more and more. Through the acrylic glass installed inside the perforated groove 19, the camera component 20 can detect the accumulation height of the desiccant inside the screening box 5 in real time, preventing the desiccant inside the screening box 5 from overflowing due to excessive amount. When the desiccant reaches a certain height, the addition of granular desiccant to the feed inlet 26 is stopped.

[0024] In another embodiment of this utility model, please refer to Figures 1 to 7A conveyor frame 21 is fixedly connected to the bottom of the inner wall of the screening chamber 1. A conveyor roller 22 is movably connected to the inner wall of the conveyor frame 21. There are multiple conveyor rollers 22. A conveyor belt 23 is installed on the outside of the multiple conveyor rollers 22. A conveyor motor 24 is installed on the outer wall of the conveyor frame 21. The output end of the conveyor motor 24 is fixedly connected to one end of the right conveyor roller 22. A collection box 25 is installed inside the screening chamber 1. The collection box 25 is located at the front end of the conveyor frame 21 and below the filter hole of the flap 17. It can hold the small volume of desiccant passing through the flap 17. After the flap 17 is opened, the granular desiccant inside the screening box 5 slides down the flap 17 to the rear end and finally falls onto the conveyor belt 23. During this process, the conveyor motor 24 runs, driving the right conveyor roller 22 to rotate, thereby causing the conveyor belt 23 to rotate clockwise and transport the standard granular desiccant out of the screening chamber 1.

[0025] In another embodiment of this utility model, please refer to Figure 1 The top of the screening chamber 1 is provided with a feed inlet 26, and the bottom of the screening chamber 1 is fixedly connected with a support leg 27. There are multiple support legs 27. The rear side of the inner wall of the screening box 5 is inclined. The filter holes are located at the front end of the guide groove 18 and are evenly distributed.
