Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a cleaning device and a material conveyor. Background Technology

[0002] In a tobacco processing line, a material conveyor is used to transport tobacco shreds. After processing in the previous stage, the shredded tobacco falls onto the conveyor belt and is transported to the next stage for further processing. The conveyor belt is equipped with a first material baffle, a second material baffle, and a third material baffle. The tobacco falls vertically, and the first, second, and third material baffles are used to prevent leakage. However, after the tobacco shreds have been transported, tobacco shreds, tobacco dust, and other materials accumulate on the edge-pressing strips on both sides of the conveyor belt. This accumulation of material on the edge-pressing strips over time is detrimental to product quality and pest control.

[0003] During routine maintenance and cleaning of the conveyor belt, cleaning personnel typically stand on an elevated platform and use a handheld compressed air machine to blow air across the conveyor belt from bottom to top, sweeping away any material that is not covered by baffles. Because the conveyor belt is positioned high up, the manual cleaning process is time-consuming and also poses certain personal safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device and a material conveyor to solve the problems of difficult and inefficient cleaning of the edge strips on both sides of the conveyor belt, thereby improving cleaning efficiency and safety.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A cleaning device for cleaning a conveyor belt and edge strip within a cleaning area enclosed by a first baffle, a second baffle, and a third baffle, characterized in that the cleaning device comprises:

[0007] Two jetting assemblies can be installed on the side of the first baffle plate near the conveyor belt and the side of the second baffle plate near the conveyor belt, respectively. The jetting assembly includes a plurality of nozzles spaced apart along the conveying direction of the conveyor belt. The nozzles are used to blow the material on the pressing strip onto the conveyor belt.

[0008] The pusher assembly includes a push rod and a pusher plate connected to each other. The push rod can pass through the third baffle plate and slide along the conveying direction. The pusher plate is located in the area to be cleaned, and the bottom of the pusher plate is in contact with the surface of the conveyor belt. The pusher plate can reciprocate between a first position and a second position to scrape the material on the conveyor belt away from the area to be cleaned when the conveyor is stationary.

[0009] As an alternative to the cleaning device, the jet assembly includes a main pipe and multiple branch pipes. The main pipe of one jet assembly is connected to the first baffle plate, and the main pipe of another jet assembly is connected to the second baffle plate. Multiple first ends of the multiple branch pipes of each jet assembly are connected to the corresponding main pipe, and each second end of each branch pipe is connected to a nozzle. Positive pressure airflow is transported along the main pipe to the multiple branch pipes connected thereto, and the material on the edge strip is blown onto the conveyor belt through the nozzle.

[0010] As an alternative to the cleaning device, the centerline of the nozzle is set perpendicular to the conveying direction, so that the spraying direction at the center of the nozzle spraying area is perpendicular to the conveying direction.

[0011] As an alternative to the cleaning device, along the conveying direction, the area covered by the positive pressure airflow ejected by any of the nozzles in the jet assembly on the surface of the edge strip partially overlaps with the area covered by the positive pressure airflow ejected by the adjacent nozzle on the surface of the edge strip.

[0012] As an alternative to the cleaning device, the distances from the multiple nozzles of the jet assembly to the pressure strip are equal.

[0013] As an alternative to the cleaning device, the multiple nozzles of the jet assembly are arranged at equal intervals along the conveying direction.

[0014] As an optional solution for the cleaning device, the third baffle plate is provided with two baffles at intervals. The side wall of the first baffle abuts against the first baffle plate, and the bottom wall of the first baffle abuts against the pressing strip connected to the first baffle plate. The side wall of the second baffle abuts against the second baffle plate, and the bottom wall of the second baffle abuts against the pressing strip connected to the second baffle plate. When the push plate is in the first position, the two side walls of the push plate abut against the sides of the two baffles that are close to each other, and the pushing surface of the push plate is coplanar with the blocking surfaces of the two baffles.

[0015] As an alternative to the cleaning device, the length A of the pusher plate is equal to the width B of the conveyor belt.

[0016] As an alternative to the cleaning device, the pusher assembly also includes a drive member, which is fixedly disposed and whose output end is connected to the end of the push rod away from the pusher plate. The drive member is used to drive the push rod to slide along the conveying direction.

[0017] A material conveyor, characterized in that it includes a first baffle plate, a second baffle plate, a third baffle plate, a conveyor belt, a pressing strip, and a cleaning device. The pressing strip is provided on both sides of the conveyor belt. The first baffle plate and the second baffle plate are respectively arranged on both sides of the conveyor belt along the conveying direction and connected to the pressing strip. The third baffle plate is respectively connected to the end of the first baffle plate and the second baffle plate opposite to the conveying direction. The cleaning device is used to clean the conveyor belt and the pressing strip in the area to be cleaned enclosed by the first baffle plate, the second baffle plate, and the third baffle plate.

[0018] Beneficial effects:

[0019] This invention provides a cleaning device and a material conveyor. The cleaning device includes two jetting assemblies and a pusher assembly. When cleaning the material conveyor, the conveyor is stopped, the conveyor belt is stationary, and jetting assemblies are installed on the side walls of the first and second baffles. Each jetting assembly has multiple nozzles arranged along the conveying direction, pointing towards the corresponding edge-pressing strip, and blowing the material on the edge-pressing strip onto the conveyor belt. Subsequently, the pusher assembly operates, with a push rod passing through the third baffle to push the pusher plate from a first position to a second position, thereby scraping the material on the conveyor belt away from the area to be cleaned enclosed by the first, second, and third baffles. Under the precise action of the cleaning device, the material on the edge-pressing strip is blown away onto the conveyor belt and then transported outside the area to be cleaned. This significantly improves cleaning efficiency, greatly reduces manual intervention, lowers the safety risks associated with manual cleaning, ensures the safety of workers, and enhances the operational stability and material transport quality of the material conveyor.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part of the device. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper" and "lower," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] This embodiment provides a material conveyor, such as Figure 1 and Figure 2As shown, the material conveyor includes a first baffle plate 101, a second baffle plate 102, a third baffle plate 103, a conveyor belt 104, a pressing strip 105, and a cleaning device. Pressing strips 105 are provided on both sides of the conveyor belt 104. The first baffle plate 101 and the second baffle plate 102 are respectively arranged on both sides of the conveyor belt 104 along the conveying direction and connected to the pressing strips 105. The third baffle plate 103 is located between the first baffle plate 101 and the second baffle plate 102, and is respectively connected to the ends of the first baffle plate 101 and the second baffle plate 102 opposite to the conveying direction. The cleaning device is used to clean the conveyor belt and pressing strip within the area to be cleaned enclosed by the first baffle plate 101, the second baffle plate 102, and the third baffle plate 103. The cleaning device can centrally clean the area to be cleaned, quickly removing tobacco material accumulated on both sides of the conveyor belt 104 and on the conveyor belt 104, reducing the workload and time of manual cleaning and improving overall cleaning efficiency. By promptly cleaning residual material, it prevents residual material from mixing with the new material being transported subsequently, ensuring the purity of the material and guaranteeing the quality of transportation.

[0031] Specifically, the material conveyor also includes two pulleys 106, which are installed at both ends of the conveyor belt 104. A motor drives one of the pulleys 106 to rotate, and the friction between the pulley 106 and the conveyor belt 104 drives the conveyor belt 104 to circulate, thereby conveying materials. To ensure that the conveyor belt 104 always maintains a good working condition, the material conveyor is equipped with a tensioning device. The tensioning device ensures that the conveyor belt 104 remains taut during operation. With increased usage time, the conveyor belt 104 may loosen due to elastic fatigue and wear of its own material. The tensioning device can manually adjust the tension according to the actual condition of the conveyor belt 104, compensating for the elongation of the conveyor belt 104, ensuring that the conveyor belt 104 remains taut at all times. A flat conveyor belt 104 provides a stable bearing surface for materials, preventing spillage and accumulation during transportation due to undulations, wrinkles, or deviation of the conveyor belt 104, thus significantly improving the stability and accuracy of material conveying. The taut conveyor belt 104 also facilitates the cleaning work. The flat conveyor belt 104 allows the cleaning device to act more evenly and effectively on the area to be cleaned enclosed by the first baffle 101, the second baffle 102 and the third baffle 103, and can better cover and clean the material residue on the surface of the edge strip 105 and the conveyor belt 104, ensuring the cleanliness and efficient operation of the entire material conveying system.

[0032] In this embodiment, the conveyor belt 104 is set at an angle to the horizontal direction, and there is a height difference between the two ends of the conveyor belt 104. The first baffle plate 101, the second baffle plate 102 and the third baffle plate 103 are all set in the vertical direction to facilitate the receiving of falling materials. The third baffle plate 103 is set at the lower end of the conveyor belt 104, and the first baffle plate 101 and the second baffle plate 102 are connected to the pressing strip 105 on the corresponding side.

[0033] like Figure 1 and Figure 2 As shown, the cleaning device includes two jet assembly 1 and a pusher assembly 2. The two jet assembly 1 can be respectively installed on the side of the first baffle 101 near the conveyor belt 104 and the side of the second baffle 102 near the conveyor belt 104. The jet assembly 1 includes a plurality of nozzles 13 spaced apart along the conveying direction of the conveyor belt 104. The plurality of nozzles 13 face the edge pressing strip 105 and are used to blow the material on the edge pressing strip 105 onto the conveyor belt 104. The pusher assembly 2 includes a push rod 21 and a pusher 22 connected to each other. The push rod 21 can pass through the third baffle 103 and can slide along the conveying direction. The pusher 22 is located in the area to be cleaned enclosed by the first baffle 101, the second baffle 102 and the third baffle 103, and the bottom of the pusher 22 is in contact with the surface of the conveyor belt 104. The pusher 22 can reciprocate between a first position and a second position to scrape the material on the conveyor belt 104 away from the area to be cleaned when the conveyor is stationary.

[0034] When cleaning the material conveyor, the conveyor stops, and the conveyor belt 104 remains stationary. Air jet components 1 are installed on the side walls of the first baffle plate 101 and the second baffle plate 102, respectively. Each air jet component 1 has multiple nozzles 13 arranged along the conveying direction, pointing towards the corresponding edge-pressing strip 105 and blowing the material on the edge-pressing strip 105 onto the conveyor belt 104. Subsequently, the pusher plate assembly 2 operates, with the push rod 21 passing through the third baffle plate 103 to push the pusher plate 22 from a first position to a second position. This causes the pusher plate 22 to scrape the material on the conveyor belt 104 away from the area to be cleaned, enclosed by the first baffle plate 101, the second baffle plate 102, and the third baffle plate 103. Under the precise action of the cleaning device, the material on the edge-pressing strip 105 is blown away onto the conveyor belt 104 and then transported outside the area to be cleaned. This significantly improves cleaning efficiency, greatly reduces manual intervention, lowers the safety risks associated with manual cleaning, ensures the safety of workers, and enhances the operational stability and material transport quality of the material conveyor.

[0035] Specifically, when the pusher plate 22 abuts against the third baffle plate 103, the position of the pusher plate 22 is defined as the first position. When the pusher plate 22 completes the material pushing action of the area to be cleaned and completely pushes out of the area of ​​the conveyor belt 104 covered by the first baffle plate 101 and the second baffle plate 102, the position of the pusher plate 22 at this time is defined as the second position.

[0036] like Figure 1 As shown, the jet assembly 1 includes a main pipe 11 and multiple branch pipes 12. The main pipe 11 of one jet assembly 1 is connected to a first baffle plate 101, and the main pipe 11 of another jet assembly 1 is connected to a second baffle plate 102. Multiple first ends of the multiple branch pipes 12 of each jet assembly 1 are connected to the corresponding main pipe 11, and each second end of each branch pipe 12 is connected to a nozzle 13. Positive pressure airflow is transported along the main pipe 11 to the multiple branch pipes 12 connected to it, and the material on the edge pressing strip 105 is blown onto the conveyor belt 104 through the nozzles 13. The positive pressure airflow generated by the jet assembly 1 acts concentrated on the edge pressing strip 105 through multiple nozzles 13, which can quickly and effectively blow the material adhering to the edge pressing strip 105 onto the conveyor belt 104, greatly reducing material residue on the edge pressing strip 105 and keeping the edge pressing strip 105 clean. Multiple nozzles 13 connected by multiple branch pipes 12 can cover a large area of ​​the edge pressing strip 105, avoiding cleaning dead corners, ensuring material cleaning of all parts of the edge pressing strip 105, and improving the comprehensiveness of cleaning.

[0037] Specifically, the jet assembly 1 also includes an air source connected to the main duct 11 to generate a positive pressure airflow. The air source is fixed outside the area to be cleaned, and the main duct 11 passes through a third baffle 103 and connects to either the first baffle 101 or the second baffle 102. The air source can be an air compressor, a fan, or an air pump.

[0038] Furthermore, such as Figure 1 As shown, the main pipe 11 is arranged horizontally, and multiple branch pipes 12 are arranged vertically. The first baffle plate 101 and the second baffle plate 102 are both provided with arc-shaped receiving grooves on their adjacent sides to accommodate the main pipe 11, branch pipes 12 and nozzles 13, so as to prevent material from falling onto the main pipe 11 of the jet assembly 1 during the operation of the material conveyor, causing material accumulation that is difficult to clean and obstructs the discharge.

[0039] Furthermore, the centerline of the nozzle 13 is set perpendicular to the conveying direction, so that the spray direction at the center of the nozzle 13's spray area is perpendicular to the conveying direction. This allows the positive pressure airflow to be concentrated and act directly on the edge-pressing strip 105. This allows the material adhering to the edge-pressing strip 105 to be subjected to a greater impact force in the vertical direction, making it easier to be blown off onto the conveyor belt 104, significantly improving the cleaning effect and efficiency of the edge-pressing strip 105.

[0040] Furthermore, along the direction perpendicular to the conveying direction, the area covered by the positive pressure airflow ejected from any nozzle 13 of one jet assembly 1 on the surface of the edge pressing strip 105 partially overlaps with the area covered by the positive pressure airflow ejected from its adjacent nozzle 13 on the surface of the edge pressing strip 105. This ensures that the entire surface of the edge pressing strip 105 is affected by the airflow. Even if there are weak cleaning edge areas in a single nozzle 13, they will be covered by the airflow from the adjacent nozzle 13, avoiding cleaning dead zones with material residue and greatly improving the cleanliness of the edge pressing strip 105.

[0041] Furthermore, such as Figure 1 As shown, the distances from the multiple nozzles 13 of the jet assembly 1 to the edge-pressing strip 105 are equal. This ensures that when the positive pressure airflow ejected from each nozzle 13 acts on the edge-pressing strip 105, the pressure and impact force are basically consistent. In this way, the cleaning force received by all parts of the edge-pressing strip 105 is uniform, and there will be no situation where some areas are over-cleaned and some areas are under-cleaned, thus making the cleaning effect of the entire edge-pressing strip 105 more uniform.

[0042] Furthermore, such as Figure 1 As shown, multiple nozzles 13 of the jet assembly 1 are arranged at equal intervals along the conveying direction. This allows the positive pressure airflow to uniformly cover the entire conveying path of the edge pressing strip 105. Each nozzle 13 is responsible for cleaning a certain area, and the equally spaced layout ensures that the cleaning areas of adjacent nozzles 13 can be connected in an orderly manner, avoiding cleaning blind spots and ensuring that the material on all parts of the edge pressing strip 105 can be effectively cleaned, thereby achieving a comprehensive and uniform cleaning effect.

[0043] like Figure 2 As shown, the third baffle plate 103 is provided with two baffle blocks 1031 spaced apart. The side wall of the first baffle block 1031 abuts against the first baffle plate 101, and the bottom wall of the first baffle block 1031 abuts against the pressing strip 105 connected to the first baffle plate 101. The side wall of the second baffle block 1031 abuts against the second baffle plate 102, and the bottom wall of the second baffle block 1031 abuts against the pressing strip 105 connected to the second baffle plate 102. When the push plate 22 is in the first position, the two side walls of the push plate 22 abut against the side of the two baffle blocks 1031 that are close to each other, and the pushing surface 221 of the push plate 22 is coplanar with the blocking surface 10311 of the two baffle blocks 1031. Figure 1 As shown, the push plate 22 is perpendicular to the conveying direction, and the third baffle plate 103 is set in the vertical direction. When the push plate 22 is in the first position, the push plate 22 and the third baffle plate 103 are set at an angle. The third baffle plate 103 has baffles 1031 on both sides of the push plate 22 to prevent the falling material from entering the dead corner area formed by the push plate 22 and the third baffle plate 103 during the operation of the material conveyor, thus preventing the formation of a cleaning dead corner.

[0044] like Figure 2 As shown, the length A of the pusher plate 22 is equal to the width B of the conveyor belt 104. This allows the pusher plate 22 to cover the entire width of the conveyor belt 104 during movement. During material conveying, regardless of how the material is distributed along the width of the conveyor belt 104, the pusher plate 22 can push it away from the conveyor belt 104 in one go, effectively preventing material residue from remaining on the edge of the conveyor belt 104, achieving comprehensive cleaning of the material on the conveyor belt 104, and ensuring the cleanliness of the conveyor belt 104.

[0045] Furthermore, the pusher assembly 2 also includes a drive component (not shown). The drive component is fixedly installed, and its output end is connected to the end of the push rod 21 away from the pusher plate 22. The drive component is used to drive the push rod 21 to slide along the conveying direction. This allows the pusher plate 22 to automatically reciprocate between the first and second positions. After the jet assembly 1 blows the material onto the conveyor belt 104, the pusher plate 22 can promptly push the material out, and after completing the cleaning task, it can return to the first position to wait for the next cleaning instruction, without manual intervention, thus improving the automation level of material cleaning. Specifically, the drive component is an electric push rod or a hydraulic cylinder.

[0046] Specifically, the start and stop of the cleaning device are controlled by the operator. Using a PLC program, the operating time, interval, and number of operations for the jet assembly 1 and the pusher assembly 2 can be precisely set. For example, appropriately extending the operating time allows the positive pressure airflow generated by the jet assembly 1 to act on the pressure strip 105 for a sufficient amount of time, effectively blowing off stubbornly attached material; it also allows the pusher assembly 2 enough time to completely push the material away from the conveyor belt 104. Setting a reasonable interval allows material to accumulate naturally on the conveyor belt 104 for a certain period, facilitating subsequent centralized cleaning. Increasing the number of operations according to actual cleaning needs allows for multiple cycles of cleaning of the area. By flexibly adjusting these parameters, cleanliness can be effectively improved, avoiding cleaning dead zones in a single operation or incomplete cleaning due to insufficient jetting or pushing time. Simultaneously, the material conveyor and the cleaning device employ an interlocking mode; the cleaning device can only be started when the material conveyor stops operating, thus preventing simultaneous operation from affecting the normal transport of materials.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
