Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco conveying equipment cleaning, and particularly relates to a cleaning device for a conveyor belt conveying device and a tobacco conveyor. BACKGROUND

[0002] In the process of tobacco production and processing, a conveyor belt conveyor, as a key conveying device for tobacco leaves, tobacco shreds and other materials, directly affects the quality of tobacco products in terms of running stability and cleanliness. Due to the light and dusty characteristics of tobacco materials, tobacco dust, dust, tobacco shreds and other impurities are easily adhered to the surface and bottom of the conveyor belt during conveying. If the impurities are not cleaned in time for a long time, the conveyor belt will be seriously worn and its service life will be shortened due to friction of the impurities, and the tobacco raw materials will be polluted and the quality of finished tobacco will be affected due to the impurities falling into the materials in the subsequent process. Meanwhile, the impurities accumulation can cause the conveyor belt to deviate and slip, thereby interfering with the continuity of production and increasing the cost of equipment maintenance.

[0003] At present, the cleaning of the tobacco conveyor mainly depends on manual operation, and common methods include manual blowing with a dust blower or wiping with a brush. However, the cleanliness of the production environment is highly required in the tobacco industry. When manually blowing, tobacco dust and dust are easily scattered in the air of the workshop, which not only causes waste of tobacco raw materials and pollution of the production environment, but also does not meet the hygiene standards of tobacco production and can be inhaled by the operator, thereby endangering health. Moreover, manual cleaning is inefficient, especially for hidden areas such as the bottom of the conveyor belt, and the cleaning is not thorough, and the problem of impurity residue is prominent.

[0004] Therefore, there is an urgent need for a cleaning device for a conveyor belt conveying device, which can solve the problem of traditional manual soot blowing causing soot scattering and polluting the workshop environment and the problem of manual soot blowing cleaning not being in place. SUMMARY

[0019] As an optional solution of the cleaning device for the conveying belt conveying equipment, the adsorption plate and the adsorption surface of the adsorption plate are arranged vertically with the conveying belt surface of the conveying belt, and the adsorption plate can adsorb the dust diffused in an adsorption space surrounded by the conveying belt, the frame and the adsorption plate and on the conveying belt.

[0020] As an optional solution of the cleaning device for the conveying belt conveying equipment, the adsorption plate is arranged at an angle with the conveying belt, and the bottom end of the adsorption plate is arranged at an angle with the dust collecting box.

[0021] As an optional solution of the cleaning device for the conveying belt conveying equipment, the buffering assembly is arranged on both sides of the frame in the left-right direction, and the buffering assembly comprises:

[0022] A hinged connecting rod set is arranged, one end of the hinged connecting rod set is hinged with the frame, and the other end of the hinged connecting rod set is hinged with the adsorption plate;

[0028] The second link has one end of the first link hinged to one end of the second link, the other end of the second link hinged to the adsorption plate, and the other end of the connecting rod hinged to the hinge joint of the first link and the second link.

[0029] As an alternative to the cleaning device for the conveyor belt conveyor, the cleaning device for the conveyor belt conveyor further includes a sliding assembly mounted on the frame, the sliding assembly comprising:

[0048] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] This embodiment provides a cleaning device for conveyor belt conveying equipment, such as... Figure 1As shown, in this embodiment, the cleaning device 10 for the conveyor belt conveying equipment includes a frame 1, a cleaning component 2, a drive component, and a buffer component 3. The frame 1 is installed at the bottom of the conveyor belt 20 and is arranged at both ends of the conveyor belt 20 in the left-right direction. The cleaning component 2 includes an adsorption plate 21, which is slidably connected to the frame 1 and extends in the left-right direction. The two ends of the adsorption plate 21 in the left-right direction are respectively slidably connected to the corresponding parts of the frame 1 in the up-down direction. The drive component is installed inside the frame 1, and the output end of the drive component is connected to the adsorption plate 21. The drive component is used to drive the adsorption plate 21 to rise to the working position, so that the adsorption plate 21 abuts against the bottom of the conveyor belt 20 to achieve adsorption cleaning. The drive component is also used to drive the adsorption plate 21 to descend to the avoidance position, so that the adsorption plate 21 is stored at the bottom of the frame 1 to achieve cleaning of the bottom of the conveyor belt 20. The buffer assembly 3 is connected to the adsorption plate 21 to avoid the impact of the driving force of the drive component. The conveyor belt 20, the frame 1 and the adsorption plate 21 can form a closed space for the cleaning process. The adsorption plate 21 can directly lock the soot, which can solve the problem of secondary pollution caused by the soot scattering and falling to the ash receiving plate after traditional manual blowing. It can also improve the cleanliness of the conveyor belt 20. When the conveyor belt 20 is working, the adsorption plate 21 is against the bottom of the conveyor belt 20. The adsorption plate 21 and the conveyor belt 20 slide relative to each other and adsorb, so as to complete the cleaning operation synchronously without the need for additional shutdown cleaning steps. At the same time, the cleaning device 10 for the conveyor belt conveying equipment can also lower the adsorption plate 21 to the avoidance position to quickly maintain the conveyor belt 20 when the adsorption plate 21 is not in use, shortening the downtime.

[0050] Preferably, such as Figure 1 As shown, in this embodiment, the cleaning component 2 also includes a negative pressure chamber 22, an air supply pipe 23, a negative pressure pump, and a pressure dividing valve 24. The negative pressure chamber 22 is located below the adsorption plate 21 and is connected to the adsorption plate 21. One end of the air supply pipe 23 is connected to the negative pressure chamber 22, and the other end of the air supply pipe 23 is connected to the negative pressure pump. The pressure dividing valve 24 is installed on the air supply pipe 23. The negative pressure generated by the negative pressure pump is transmitted to the negative pressure chamber 22 connected to the adsorption plate 21 after being adjusted by the air supply pipe 23 and the pressure dividing valve 24. This allows the adsorption plate 21 to form a stable and controllable adsorption force, which enhances the locking and adsorption effect on the soot at the bottom of the conveyor belt 20. The pressure dividing valve 24 flexibly adjusts the adsorption intensity to adapt to different cleaning needs, avoids secondary pollution caused by soot scattering, improves the cleanliness of the conveyor belt 20, and does not interfere with the switching of the adsorption plate 21 between the working position and the avoidance position, ensuring the convenience of equipment maintenance and the reduction of downtime.

[0051] Preferably, in this embodiment, the negative pressure chamber 22 includes a grooved structure and a dust receiving plate molded from ABS plastic. The bottom end of the dust receiving plate is connected to the grooved structure, and the top end of the dust receiving plate is connected to the adsorption plate 21. This allows the negative pressure chamber 22 to form a stable negative pressure channel with the ABS plastic-molded grooved structure and the dust receiving plate. The properties of ABS plastic ensure the structural strength and sealing of the negative pressure chamber 22, ensuring that the adsorption force is stably transmitted to the adsorption plate 21 to enhance the ash locking effect. The dust receiving plate also collects the adsorbed ash, preventing secondary pollution caused by the accumulation or dispersion of ash in the negative pressure chamber 22. The combination design of the grooved structure and the dust receiving plate is adapted to the installation and connection requirements of the adsorption plate 21, without affecting the lifting, switching, cleaning, and obstacle avoidance functions of the adsorption plate 21. Together with components such as the negative pressure pump and the pressure dividing valve 24, it continuously improves the efficiency and cleanliness of the conveyor belt 20.

[0052] Preferably, such as Figure 1 As shown, in this embodiment, the adsorption surface of the adsorption plate 21 is provided with adsorption holes 211 arranged in a matrix. The adsorption holes 211 are evenly distributed along the length and width directions of the adsorption plate 21. The adsorption holes 211 are connected to the negative pressure chamber 22 to form a negative pressure adsorption channel. The matrix-distributed adsorption holes 211 can expand the adsorption contact range between the adsorption plate 21 and the bottom of the conveyor belt 20, improve the adsorption uniformity, comprehensively lock and adsorb the soot at all parts of the bottom of the conveyor belt 20, enhance the stability of negative pressure adsorption, avoid secondary pollution caused by local soot residue or dispersion, and improve the cleanliness and efficiency of the conveyor belt 20. In other embodiments, the adsorption holes 211 can also be arranged in a honeycomb or staggered pattern.

[0053] Preferably, in this embodiment, 6-8 fine sealing holes of 2-3mm are distributed per 10 square centimeters, with the hole diameter matching the diameter of the ash particles. This achieves precise locking, avoids missed suction, and reduces the possibility of particles clogging the pores. At the same time, the reasonable density of 6-8 fine sealing holes per 10 square centimeters ensures uniform transmission of adsorption force, resulting in a comprehensive cleaning effect on the ash at the bottom of the conveyor belt 20. The negative pressure chamber 22 is adapted to the existing air source system in the workshop, without the need for additional modification of the air source equipment. The pressure distribution valve 24 is a graded regulating valve that is adjustable from 0.02-0.05MPa, which can adjust the adsorption force according to the differences in ash in processes such as shredding and drying. It can lock and adsorb different types of ash, avoiding missed suction or over-adsorption that could damage the conveyor belt 20.

[0054] Preferably, such as Figure 1As shown, in this embodiment, the cleaning component 2 also includes a dust collection box, which is set at the bottom of the conveyor belt 20. The dust collection box is used to collect the dust falling from the adsorption plate 21 and to catch the dust that the adsorption plate 21 cannot adsorb in time, forming a double protection of precise adsorption and bottom catching, avoiding secondary pollution caused by dust drifting or falling into the workshop environment, and realizing the centralized and unified collection and convenient treatment of all dust.

[0055] Preferably, such as Figure 1 As shown, in this embodiment, the adsorption plate 21 and its adsorption surface are arranged perpendicularly to the surface of the conveyor belt 20. The adsorption plate 21 can adsorb the dust that is diffused in the adsorption space formed by the conveyor belt 20, the frame 1 and the adsorption plate 21 and on the conveyor belt 20. It can directly adsorb the dust on the conveyor belt 20 and lock the dust diffused in the space. This avoids the secondary pollution caused by the scattering of soot and falling onto the dust receiving plate caused by traditional manual blowing from the source. It enhances the locking and adsorption effect of the adsorption plate 21 on the dust at the bottom of the conveyor belt 20 and improves the cleanliness of the conveyor belt 20.

[0056] In other embodiments, the adsorption plate 21 and the conveyor belt 20 are set at an angle, with the bottom end of the adsorption plate 21 inclined against the ash collection box. This optimizes the sealing of the enclosed cleaning space, bringing the adsorption plate 21 and the conveyor belt 20 closer together, thus improving the locking and adsorption efficiency of ash. At the same time, the inclined structure guides any dust that is not completely locked on the adsorption plate 21 to slide down the inclined surface to the ash collection box, forming a more comprehensive double protection with the ash collection box. This avoids secondary pollution caused by dust scattering or falling, without affecting the switching of the adsorption plate 21 between the working position and the avoidance position with the drive component, and without interfering with the synchronous cleaning operation of the conveyor belt 20. It also reduces the dust residue on the adsorption plate 21, improves the cleanliness of the conveyor belt 20, and facilitates the centralized and unified collection and treatment of dust, ensuring convenient equipment maintenance and shortening downtime.

[0057] Preferably, such as Figure 1As shown, in this embodiment, the buffer assembly 3 is disposed on both sides of the frame 1 along the left-right direction. The buffer assembly 3 includes a hinged connecting rod assembly 31, a connecting rod 32, a spring 33, and a fixing member 34. One end of the hinged connecting rod assembly 31 is hinged to the frame 1, and the other end is hinged to the adsorption plate 21. One end of the connecting rod 32 is hinged to the internal hinge of the hinged connecting rod assembly 31. One end of the spring 33 is connected to the corresponding end of the connecting rod 32, and the other end of the spring 33 is connected to the fixing member 34. The fixing member 34 is fixedly installed on the external fixing structure. When the driving member drives the adsorption plate 21 to rise, the hinged connecting rod assembly 31 is compressed, causing the connecting rod 32 to rise, which in turn causes the spring 33 to stretch. Since the fixing member 34 is fixed, the spring 33 is stretched. The device is fixedly installed on an external structure. The spring force of the spring 33 can buffer the impact of the driving force of the drive component. When the spring 33 is stretched to its elastic limit, that is, when the adsorption plate 21 reaches the working position, the buffer component 3 can limit the adsorption plate 21 from rising too much and avoid rigid compression damage to the conveyor belt 20. When the drive component drives the adsorption component to descend, the hinged linkage 31 is stretched, the connecting rod 32 descends and drives the spring 33 to reset and be compressed. When the spring 33 reaches its compression limit, that is, when the adsorption plate 21 reaches the avoidance position, the buffer component can limit the adsorption plate 21 from falling too much and avoid rigid collision between the adsorption plate 21 and the bottom of the frame 1 and other structures at the bottom of the adsorption plate 21.

[0058] Preferably, such as Figure 1 As shown, in this embodiment, the hinged linkage assembly 31 includes a first link 311 and a second link 312. One end of the first link 311 is hinged to the top of the frame 1, and the other end of the first link 311 is hinged to one end of the second link 312. The other end of the second link 312 is hinged to the adsorption plate 21, and the other end of the connecting rod 32 is hinged to the hinge joint of the first link 311 and the second link 312. This allows the adsorption plate 21 to be stably guided to move vertically through the relative rotation of the first link 311 and the second link 312 during its ascent or descent, while simultaneously controlling the displacement of the adsorption plate 21. The motion is transmitted to the connecting rod 32 to drive the spring 33 to extend and retract. The hinged connection between the connecting rods ensures the stability and accuracy of the motion trajectory of the adsorption plate 21 during lifting and lowering, preventing the adsorption plate 21 from shifting and affecting the adhesion effect with the conveyor belt 20 or the accuracy of the storage position. The motion of the adsorption plate 21 is converted into the elastic deformation of the spring 33, which can more efficiently cooperate with the buffer component 3 to buffer the impact of the driving force. When the adsorption plate 21 reaches the working position or avoidance position, the synergistic effect of the connecting rod and the spring 33 enhances the limiting effect, further protecting the conveyor belt 20 and the equipment structure, and improving the reliability of the cleaning device operation.

[0059] Preferably, in this embodiment, the cleaning device 10 for the conveyor belt conveying equipment further includes a sliding component. The sliding component is mounted on the frame 1 and includes a slide rail and a slider. The slide rail is mounted on the frame 1 and extends in the vertical direction. The slider is connected to the adsorption element and is slidably mounted on the slide rail. The slider can slide along the extension direction of the slide rail, enabling the adsorption element to slide smoothly and accurately in the vertical direction. This ensures that the path of the adsorption plate 21 when it rises to the working position is smooth and stable, and that the adsorption plate 21 reliably abuts against the bottom of the conveyor belt 20. This ensures the airtightness of the sealed space formed by the conveyor belt 20, the frame 1, and the adsorption plate 21, improves the ash locking effect and cleanliness, and also enables the adsorption plate 21 to descend smoothly and stably to the avoidance position, reducing jamming during the sliding process, extending the service life of the device, and ensuring the efficient and orderly conduct of cleaning operations and equipment maintenance.

[0060] Preferably, in this embodiment, the cleaning device 10 for the conveyor belt conveying equipment further includes a locking component. The locking component is a quick-release and quick-lock structure. The quick-lock structure is installed on the frame 1 and connected to the adsorption plate 21. It is used to quickly lock the position of the adsorption plate 21 when it rises to the working position or falls to the avoidance position. At the same time, it is easy to unlock and disassemble when adjustment is needed, ensuring the stability of the cleaning operation, simplifying the equipment adjustment process, shortening the downtime maintenance time, and enhancing the flexibility and convenience of the device.

[0061] Preferably, in this embodiment, the driving component is a cylinder, which stably outputs driving force to drive the adsorption plate 21 to slide up and down along the frame 1, accurately switching the adsorption plate 21 between the working position abutting the bottom of the conveyor belt 20 and the avoidance position stored at the bottom of the frame 1. The cylinder, together with the buffer component 3, can effectively buffer the impact, ensuring reliable contact between the adsorption plate 21 and the bottom of the conveyor belt 20 to form a closed cleaning space, avoiding secondary pollution caused by the scattering of soot from the source, improving the cleanliness of the conveyor belt 20, and completing the cleaning operation simultaneously when the conveyor belt 20 is working without additional downtime. When not in use, the adsorption plate 21 can be quickly lowered to the avoidance position for maintenance of the conveyor belt 20, further shortening downtime.

[0062] This embodiment also provides a tobacco transport aircraft, such as Figure 1As shown, in this embodiment, the tobacco conveyor includes a conveyor belt 20 and a cleaning device 10 for the conveyor belt. The cleaning device 10 is located below the conveyor belt 20 and is used to adsorb and remove tobacco dust, tobacco fragments, and impurities adhering to the bottom of the conveyor belt 20 in real time. This prevents the accumulation of pollutants from affecting the operational stability of the conveyor belt 20 and the cleanliness of the tobacco transport. It solves the problem of secondary pollution caused by traditional manual blowing, where tobacco ash scatters and falls onto the ash collection plate, still polluting the workshop environment. This improves the cleanliness of the conveyor belt 20 and allows the cleaning operation to be completed simultaneously with the conveyor belt 20 without additional machine downtime. When the cleaning function is not in use, the adsorption plate 21 can be lowered to a clearance position to achieve quick maintenance of the conveyor belt 20, further shortening downtime and ensuring the efficiency and cleanliness of tobacco transport.
