Description

Technical Field

[0001] This invention belongs to the field of conveying, processing and screening technology, specifically an automatic cleaning device for a high-level vibrating conveyor. Background Technology

[0002] Tobacco processing refers to the handling and processing of raw tobacco materials to transform them into finished tobacco products. This process includes multiple stages, such as procurement, processing, formulation, processing, packaging, and quality control. First, suitable raw tobacco materials are procured. Next, the procured tobacco leaves need to undergo processing, including dehydration, fermentation, and drying, to achieve the desired state. These processing steps all affect the taste, aroma, and nicotine content of the tobacco leaves.

[0003] The shredder in a tobacco processing workshop plays a crucial role in the tobacco leaf processing process. It cuts whole tobacco leaves into fine shreds, sorts and grades them according to specifications, and performs special tobacco shredding treatments. This processing meets the production needs of different types of cigarettes, ensuring the tobacco shreds meet specific requirements for length, width, softness, and moisture content, providing a good raw material foundation for subsequent blending and manufacturing. The efficient operation and precise cutting capabilities of the shredder have a significant impact on the quality and production efficiency of tobacco products.

[0004] In traditional tobacco processing workshops, after the tobacco shredder finishes its work, a conveyor belt drives the material through a screen located below. In the tobacco processing workshop, the shredder uses a vertical feeding method, employing a high-level vibrating conveyor to transport the material vertically to the shredder's hopper. There, the upper and lower copper chains of the shredder compact the material into a "tobacco cake" which is then conveyed to the cutting gate. During production, the team discovered that the high-level vibrating conveyor frequently experienced screen clogging during transport, preventing timely removal of tobacco leaf fragments and thus affecting the subsequent shredding process.

[0005] This invention provides a solution to the problems of easy clogging of screen holes and unclean upper surface of vibrating screen in traditional tobacco processing workshops. Summary of the Invention

[0006] The purpose of this invention is to solve the problems mentioned above, such as easy clogging of screen holes and unclean upper surface of vibrating screen in traditional tobacco processing workshops, and to provide an automatic cleaning device for high-level vibrating conveyors.

[0007] The technical solution adopted in this invention is as follows: an automatic cleaning device for a high-level vibrating conveyor, including a main vibrating screen, a high-frequency vibrating motor fixedly connected to the lower surface of the main vibrating screen, an auxiliary vibrating screen provided below the main vibrating screen, the main vibrating screen and the auxiliary vibrating screen being connected by a number of linkage springs, side support frames provided on both sides of the main vibrating screen, a cleaning device body provided on the side support frames, a cleaning brush provided on the cleaning device body, and the position of the cleaning brush corresponding to the position of the main vibrating screen.

[0008] The aforementioned automatic cleaning device for a high-position vibrating conveyor has chains on the side support frames on both sides, and displacement teeth on the cleaning equipment body corresponding to the chain. The side support frames and the cleaning equipment body are connected by chains and displacement teeth. The cleaning equipment body is equipped with a main cylinder, and a cleaning support shell is provided at the output end of the main cylinder. A high-power motor is connected to the end of the cleaning support shell away from the main cylinder, and the high-power motor is connected to the cleaning brush.

[0009] In the above-mentioned automatic cleaning device for a high-position vibrating conveyor, the main cylinder is located in the groove of the main body of the cleaning equipment and is not higher than the main body of the cleaning equipment. An auxiliary cylinder is provided above the main cylinder. The two sides of the auxiliary cylinder are fixed to the upper surface of the main body of the cleaning equipment by support blocks. The output end of the auxiliary cylinder is opposite to that of the main cylinder. The output end of the auxiliary cylinder is fixed to the vertical end of the inclined plate. The inclined plate is L-shaped, and the horizontal end of the inclined plate is inserted between the main cylinder and the main body of the cleaning equipment.

[0010] The aforementioned automatic cleaning device for a high-position vibrating conveyor has a displacement power body at one end of the side support frame near the inclined plate. The displacement power body contains a high-precision motor, and the output end of the high-precision motor has an active tooth that meshes with the driven tooth on the transmission rod. Both ends of the transmission rod have active wheels that drive the chain to move.

[0011] The above-mentioned automatic cleaning device for a high-level vibrating conveyor has a dust collection box below the auxiliary vibrating screen. A support fine-tuning base and a threaded rod are arranged sequentially on the bottom surface of the dust collection box. The threaded rod passes through the auxiliary vibrating screen, and an adjusting wheel is provided below the auxiliary vibrating screen and on the threaded rod.

[0012] The aforementioned automatic cleaning device for a high-position vibrating conveyor has a swing arm connected to the output end of a high-torque motor, and the swing arm is connected to a support rod at the bottom of the debris collection box.

[0013] The aforementioned automatic cleaning device for a high-position vibrating conveyor has a mechanical housing surrounding the high-torque motor.

[0014] The aforementioned automatic cleaning device for a high-level vibrating conveyor has several pairs of opposing swing arms on both sides of the dust collection box, and the corresponding swing arms on both sides are connected by a support beam.

[0015] The aforementioned automatic cleaning device for a high-level vibrating conveyor has a support body fixedly connected to the lower surface of the side support frame.

[0016] By adopting the above technical solution, during use, tobacco enters the upper surface of the main vibrating screen from above. The high-frequency vibrating motor below generates high-frequency vibration on the main vibrating screen, mechanically shaking the tobacco leaves conveyed above the screen. This causes the tobacco leaves to shift, facilitating the shaking off of tobacco leaf fragments to the bottom, where they pass through the screening mesh of the main vibrating screen and are collected in the fragment collection box. The auxiliary vibrating screen has a similar effect to the main vibrating screen, providing buffering during the high-frequency vibration of the main vibrating screen. Together with the linkage spring, it enhances the frequency of back-and-forth shaking during screening, reducing screen clogging, improving efficiency, and reducing fragmentation in the subsequent shredding process. The side support frame and the main body of the cleaning equipment work together to support the back-and-forth movement of the main cylinder above the equipment. The main cylinder can extend forward to clean the upper surface of the main vibrating screen. By turning on the high-power motor, the cleaning brush rotates and rolls, allowing residual tobacco leaves on the upper surface of the main vibrating screen to be cleaned when not in use, preparing for the next operation. The cleaning support shell provides a buffering effect.

[0017] The beneficial effects of this invention are:

[0018] In this invention, during use, tobacco leaves enter the upper surface of the main vibrating screen through the upper section of the vibrating groove. The high-frequency vibrating motor below generates high-frequency vibration on the main vibrating screen, mechanically shaking the tobacco leaves conveyed above the screen, thereby displacing the tobacco leaves and facilitating the shaking off of tobacco leaf fragments to the bottom. These fragments then pass through the screening mesh of the main vibrating screen and are collected in the fragment collection box. The auxiliary vibrating screen has a similar effect to the main vibrating screen, providing buffering during the high-frequency vibration of the main vibrating screen. Together with the linkage spring, it enhances the frequency of the back-and-forth shaking during screening, reducing screen clogging, improving efficiency, and reducing fragmentation in the subsequent shredding process. The side support frame and the main body of the cleaning equipment work together to support the back-and-forth movement of the main cylinder above the equipment.

By turning on the high-power motor, the cleaning brush rotates and rolls, allowing residual tobacco leaves and other debris to be cleaned from the upper surface of the main vibrating screen when not in use, preparing it for the next operation. The cleaning support shell provides a buffering effect. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] An automatic cleaning device for a high-level vibrating conveyor includes a main vibrating screen 1, a high-frequency vibrating motor 4 fixedly connected to the lower surface of the main vibrating screen 1, an auxiliary vibrating screen 2 below the main vibrating screen 1, the main vibrating screen 1 and the auxiliary vibrating screen 2 being connected by a number of linkage springs 3, side support frames 5 on both sides of the main vibrating screen 1, a cleaning equipment body 6 on the side support frames 5, and a cleaning brush 10 on the cleaning equipment body 6, the position of the cleaning brush 10 corresponding to the position of the main vibrating screen 1.

[0030] Chains 14 are installed on the side support frames 5 on both sides. Displacement teeth 15 are installed on the main body 6 of the cleaning equipment at positions corresponding to the chains 14. The side support frames 5 and the main body 6 of the cleaning equipment are connected by the chains 14 and the displacement teeth 15. A main cylinder 7 is installed on the main body 6. A cleaning support shell 8 is installed at the output end of the main cylinder 7. A high-power motor 9 is connected to the end of the cleaning support shell 8 away from the main cylinder 7. The high-power motor 9 is connected to the cleaning brush 10. The displacement teeth 15 are fixed at the main body 6 and engaged with the chains 14. The main body 6 of the cleaning equipment moves back and forth through the transmission of the chains 14, thereby moving the entire unit.

[0031] The main cylinder 7 is located in the groove of the main body 6 of the cleaning equipment and is not higher than the main body 6 of the cleaning equipment. An auxiliary cylinder 12 is provided above the main cylinder 7. The two sides of the auxiliary cylinder 12 are fixed to the upper surface of the main body 6 of the cleaning equipment through support blocks 11. The output end of the auxiliary cylinder 12 is opposite to that of the main cylinder 7. The output end of the auxiliary cylinder 12 is fixed to the vertical end of the inclined plate 13. The inclined plate 13 is L-shaped, and the horizontal end of the inclined plate 13 is inserted between the main cylinder 7 and the main body 6 of the cleaning equipment.

[0032] The extension and retraction of the auxiliary cylinder 12 drives the inclined plate 13. The inclined block below the inclined plate 13 is inserted into the gap between the main body 6 of the cleaning equipment and the main cylinder 7. Under normal circumstances, the center of gravity of the main cylinder 7 is close to the main body 6 of the cleaning equipment. The overall cleaning structure, including the cleaning support shell 8, the high-power motor 9, and the cleaning brush 10, is slightly tilted downwards. After the inclined plate 13 is inserted, the main cylinder 7 tilts downwards at a larger angle at the main body 6 of the cleaning equipment, making it easier for the cleaning brush 10 to clean the main vibrating screen 1. The position of the cleaning brush 10 can be adjusted by the depth of the inclined plate 13 inserted into the main cylinder 7 and the main body 6 of the cleaning equipment, thereby achieving the cleaning of the main vibrating screen 1.

[0033] The overall function is to shift the center of gravity of the auxiliary cylinder 12 to the main body 6 of the cleaning equipment, ensuring the stability of the cleaning structure when the main body 6 of the cleaning equipment moves back and forth.

[0034] A displacement power unit 19 is located at one end of the inclined plate 13 of the side support frame 5. A high-precision motor 21 is installed inside the displacement power unit 19. The output end of the high-precision motor 21 has a drive gear 20, which meshes with the driven gear on the transmission rod 18. Both ends of the transmission rod 18 have drive wheels 17, which drive the chain 14. The displacement power unit 19 provides the installation conditions for the overall transmission equipment. The driven wheel 16 and drive wheel 17 ensure the cyclic operation of the chain 14 within the side support frame 5, guaranteeing the stability of the chain 14. The transmission rod 18 provides the necessary conditions for the force transmission of the equipment. The high-precision motor 21 is fixed inside the displacement power unit 19, providing mechanical power for the forward and backward movement of the cleaning equipment body 6. The drive gear 20 ensures stable and effective force transmission of the equipment.

[0035] Below the auxiliary vibrating screen 2 is a dust collection box 23. On the bottom surface of the dust collection box 23 are a supporting fine-tuning base 22 and a threaded rod 25. The threaded rod 25 passes through the auxiliary vibrating screen 2. Below the auxiliary vibrating screen 2 and on the threaded rod 25, an adjusting wheel 24 is located. The adjusting wheel 24 can rotate above the threaded rod 25, thereby pushing the dust collection box 23 up or down. This ensures more efficient entry of tobacco leaves and facilitates rapid screening of dust.

[0036] The output end of the high-torque motor 30 is connected to a swing rod 29, which is connected to a support rod 28 at the bottom of the debris collection box 23. The swing rod 29, through force transmission, provides cyclical operation for the equipment, causing the main vibrating screen 1, auxiliary vibrating screen 2, linkage spring 3, and debris collection box 23 to vibrate as a whole, accelerating the screening process. After receiving the electrical signal, the high-torque motor 30 and the high-frequency vibrating motor 4 operate simultaneously, allowing the main vibrating screen 1 to vibrate at a higher frequency, dislodging the stalks and debris blocking the mesh.

[0037] The high-torque motor 30 provides mechanical power for the shaking of the dust collection box 23. The high-torque motor 30 is equipped with a mechanical housing 31. The mechanical housing 31 protects the high-torque motor 30, preventing accidental contact by the user and facilitating overall weight support for the equipment.

[0038] The waste collection box 23 has several pairs of opposing swing arms 26 on both sides, and the corresponding swing arms 26 on both sides are connected by support beams 27. The upper part of the swing arms 26 corresponds to the waste collection box 23, and the support beams 27 facilitate the fixation of the equipment, thereby allowing the swing arms 26 to mechanically shake the screening part of the equipment.

[0039] A support body 32 is fixedly connected to the lower surface of the side support frame 5. The support body 32 provides support for the entire equipment.

[0040] In use, tobacco enters the upper surface of the main vibrating screen 1 from above. The high-frequency vibrating motor 4 below generates high-frequency vibration on the main vibrating screen 1, mechanically shaking the tobacco leaves conveyed above the screen. This causes the tobacco leaves to shift, making it easier to shake off tobacco fragments to the bottom, thus passing through the screening mesh of the main vibrating screen 1 to the fragment collection box 23 for collection. The auxiliary vibrating screen 2 has a similar effect to the main vibrating screen 1, providing a buffer during the high-frequency vibration of the main vibrating screen 1. Together with the linkage spring 3, it strengthens the frequency of the back-and-forth shaking of the screen, reduces screen blockage, improves efficiency, and reduces the breakage in the subsequent shredding process. The side support frame 5 and the main body of the cleaning equipment 6 work together to support the main cylinder 7 above the equipment to move back and forth. The main cylinder 7 can extend forward to clean the upper surface of the main vibrating screen 1. By turning on the high-power motor 9, the cleaning brush 10 rotates and rolls to clean the residual tobacco leaves on the upper surface of the main vibrating screen 1, providing conditions for the next operation. The cleaning support shell 8 provides a buffering effect.

[0041] The implementation principle of an embodiment of the automatic cleaning device for a high-level vibrating conveyor of the present invention is as follows:

[0042] In operation, tobacco enters the upper surface of the main vibrating screen 1 from above. The high-frequency vibrating motor 4 below generates high-frequency vibration on the main vibrating screen 1, mechanically shaking the tobacco leaves and causing them to shift. This facilitates the shaking of tobacco fragments onto the auxiliary vibrating screen 2, which then vibrates mechanically, causing any fragments that pass through it to fall into the fragment collection box 23 for collection. The high-frequency vibration of the main vibrating screen 1 provides a buffer, working in conjunction with the linkage spring 3 to increase the frequency of the shaking before and after screening, reducing screen blockage, improving efficiency, and minimizing fragmentation in subsequent shredding processes. The main cylinder 7 and high-power motor 9 on the main body 6 of the cleaning equipment are activated, causing the cleaning brush 10 to rotate. The high-precision motor 21 is then activated, sequentially driving the drive gear 20, transmission rod 18, chain 14, displacement gear 15, and the main body 6 of the cleaning equipment to rotate. The cleaning brush 10 cleans residual tobacco leaves and other debris from the upper surface of the main vibrating screen 1, preparing it for the next operation. The cleaning support shell 8 provides a buffer for the cleaning brush 10.

[0043] The extension and retraction of the auxiliary cylinder 12 drives the inclined plate 13. The inclined block below the inclined plate 13 is inserted into the gap between the main body 6 of the cleaning equipment and the main cylinder 7. Under normal circumstances, the center of gravity of the main cylinder 7 is close to the main body 6 of the cleaning equipment. The overall cleaning structure, including the cleaning support shell 8, the high-power motor 9, and the cleaning brush 10, is slightly tilted downwards. After the inclined plate 13 is inserted, the main cylinder 7 is between the main body 6 of the cleaning equipment, making the downward tilt angle of the main cylinder 7 larger, which makes it easier for the cleaning brush 10 to clean the main vibrating screen 1. The overall function is to move the center of gravity of the auxiliary cylinder 12 into the main body 6 of the cleaning equipment, ensuring the stability of the cleaning structure when the main body 6 of the cleaning equipment moves back and forth.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
