Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Embodiments of this application provide a cleaning device for a negative pressure dust removal pipeline in tobacco production, including a negative pressure conveying pipe 100, a negative pressure dust removal pipe body 110, a filter plate 120, a rebound drive assembly 140, and a vibration assembly 130.

[0024] like Figure 1 As shown, the negative pressure dust removal pipe body 110 is connected to the negative pressure conveying pipe 100.

[0025] For example, the negative pressure delivery pipe 100 is L-shaped.

[0026] like Figure 2 or Figure 3 As shown, the filter plate 120 is movably installed in the negative pressure dust removal pipe body 110.

[0027] like Figures 1 to 3 As shown, the vibration assembly 130 is installed in the negative pressure dust removal pipe and is used to drive the filter plate 120 to move in order to clean the debris on the filter plate 120.

[0028] The rebound drive assembly 140 is disposed in the negative pressure dust removal pipe and is used to drive the filter plate 120 to reset.

[0029] The vibration component 130 drives the filter plate 120 to move, and the rebound drive component 140 drives the filter plate 120 to reset. The rebound drive component 140 and the vibration component 130 work together to make the filter plate 120 vibrate back and forth, thereby cleaning the filter plate 120.

[0030] The filter plate 120 is used to filter waste such as paper scraps, so that the waste continues to be transported by the negative pressure conveying pipe 100, while the tobacco raw materials pass through the filter plate 120 and are transported and collected by the negative pressure dust removal pipe body 110, reducing the waste of tobacco raw materials and reducing economic losses. At the same time, the vibration component 130 and the rebound drive component 140 drive the filter plate 120 to vibrate, preventing the filter plate 120 from clogging.

[0031] like Figure 2 As shown, in one embodiment, the vibration assembly 130 includes a telescopic rod 138, one end of which is fixedly connected to the filter plate 120, for example by welding, snap-fitting, or bolting.

[0032] The other end of the telescopic rod 138 is fixedly connected to the inner wall of the negative pressure dust removal pipe body 110. The telescopic rod 138 extends and retracts to drive the filter plate 120 to move back and forth, thereby cleaning the filter plate 120.

[0033] The telescopic rod 138 is fixed to the negative pressure dust removal pipe body 110 by means of welding, snap-fitting or bolt connection, etc.

[0034] For example, the telescopic rod 138 includes, but is not limited to, a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, an electric actuator telescopic mechanism, a threaded screw telescopic mechanism, or a linear motor 131.

[0035] Unlike the technical solution in the above embodiments where the vibration component 130 includes a telescopic rod 138, such as... Figure 3 and Figure 4 As shown, in another embodiment, the vibration assembly 130 includes a motor 131, a rotating shaft 132, a rotating block 133, a movable rod 134, a moving frame 135, a moving rod 136, and a vibration bar 137.

[0036] The motor 131 is fixedly connected to the inner wall of the negative pressure dust removal pipe body 110, and the fixing method is, for example, welding, gluing, snap-fitting or bolt connection.

[0037] The output shaft of motor 131 is vertically fixed to one end of rotating shaft 132 by means of welding, snap-fit ​​or bolt connection.

[0038] The other end of the rotating shaft 132 is vertically fixed to one end of the rotating block 133 by means of welding, snap-fit ​​or threaded connection.

[0039] The other end of the rotating block 133 is vertically fixed to one end of the movable rod 134 by means of welding, snap-fitting or bolt connection.

[0040] The movable frame 135 is provided with a sliding groove, and the other end of the movable rod 134 is slidably installed in the sliding groove of the movable frame 135.

[0041] A sliding groove is provided on the inner wall of the negative pressure dust removal pipe body 110. The movable frame 135 is slidably installed in the sliding groove on the inner wall of the negative pressure dust removal pipe body 110. The side of the movable frame 135 closest to the filter plate 120 is connected to the filter plate 120 via a transmission.

[0042] During use, the motor 131 rotates, driving the rotating shaft 132 and the rotating block 133 to rotate. The rotating block 133 rotates, driving the movable rod 134 to rotate around the output shaft of the motor 131. The movable rod 134 rotates, driving the moving frame 135 to move back and forth. The moving frame 135 moves back and forth, driving the filter plate 120 to move, thereby cleaning the filter plate 120 by vibration.

[0043] For example, in order to ensure that the moving frame 135 moves smoothly back and forth within the negative pressure dust removal pipe body 110, a sliding fit groove is provided on each of the two oppositely arranged inner walls of the negative pressure dust removal pipe body 110, so that each end of the moving frame 135 is located in a sliding fit groove, thereby ensuring that both ends of the moving frame 135 can move back and forth in the sliding fit groove.

[0044] like Figure 3 As shown, in one embodiment, the vibration assembly 130 further includes a moving rod 136 and a vibration bar 137.

[0045] One end of the moving rod 136 is fixedly connected to the side wall of the moving frame 135 near the filter plate 120 by welding, snap-fit ​​or bolt connection, and the other end of the moving rod 136 is fixedly connected to the vibrating strip 137 by welding, snap-fit ​​or bolt connection, and the vibrating strip 137 abuts against the filter plate 120.

[0046] The vibration strip 137 increases the contact area with the filter plate 120, making the force exerted by the moving frame 135 on the filter plate 120 more balanced, thereby making the vibration of the filter plate 120 more stable.

[0047] like Figure 3 As shown, in one embodiment, the vibration bar 137 includes a mounting base 1371, which is fixedly connected to the other end of the moving rod 136 by means of welding, snap-fitting or bolting.

[0048] The reciprocating movement of the moving rod 136 drives the mounting base 1371 to reciprocate, and the mounting base 1371 is used to drive the filter plate 120 to move.

[0049] like Figure 3 As shown, in one embodiment, the vibration bar 137 further includes a flexible block 1372, which is fixedly mounted on the mounting base 1371. The flexible block 1372 abuts against the filter plate 120 so that the flexible block 1372 can push the filter plate 120 to move away from the motor 131, and then the rebound drive assembly 140 resets the filter plate 120.

[0050] The flexible block 1372 is provided to protect the filter plate 120 from direct impact from the mounting base 1371.

[0051] For example, the flexible block 1372 is made of a flexible material, which is at least one of the following: sponge, silicone, latex, rubber, polyurethane, polystyrene, natural / synthetic fibers, etc.

[0052] In one embodiment, the spring-loaded drive assembly 140 includes a spring, one end of which is fixedly disposed on the inner wall of the negative pressure dust removal pipe body 110, and the other end of which is fixedly connected to the filter plate 120. The spring can extend and retract to push back and reset the filter plate 120.

[0053] Unlike the spring-driven assembly 140 in the above embodiments, such as Figure 3 and Figure 5 As shown, in another embodiment, the rebound drive assembly 140 includes a housing 141, a connecting rod 142, and an elastic element 143.

[0054] The housing 141 is fixedly installed on the inner wall of the negative pressure dust removal pipe body 110, and the fixing method is such as welding, snap-fitting or bolt connection.

[0055] A sliding through hole is provided on the housing 141.

[0056] The connecting rod 142 has two ends. One end of the connecting rod 142 passes through the sliding through hole of the housing 141 and is slidably installed in the housing 141 and connected to the elastic element 143. The other end of the connecting rod 142 is fixedly connected to the filter plate 120.

[0057] The elastic element 143 drives the connecting rod 142 to reset, and the connecting rod 142 drives the filter plate 120 to reset.

[0058] For example, the elastic element 143 includes, but is not limited to, helical springs, wave springs, disc springs, ring springs, leaf springs, steel leaf springs, rubber springs, air springs, etc.

[0059] To prevent external debris from entering the housing 141, such as Figure 5 As shown, in one embodiment, a sealing ring 144 is provided at the sliding through hole of the housing 141. The sealing ring 144 is sleeved on the connecting rod 142 and is in a sealing fit with the connecting rod 142.

[0060] The sealing ring 144 is, for example, a rubber ring or a silicone ring.

[0061] In order for the connecting rod 142 to return to its original position smoothly, such as Figure 5 As shown, in one embodiment, a sliding rod 145 is vertically mounted on one end of the connecting rod 142, and a sliding groove is provided on the inner wall of the housing 141. The sliding rod 145 is slidably mounted in the sliding groove, and the inner wall of the sliding groove limits the movement path of the sliding rod 145, thereby limiting the movement path of the connecting rod 142.

[0062] To ensure the smooth reset of the filter plate 120, such as Figure 3 As shown, in one embodiment, two rebound drive components 140 are provided. One rebound drive component 140 is provided on one of the inner walls of the negative pressure dust removal pipe body 110, and the other rebound drive component 140 is provided on the opposite inner wall of the negative pressure dust removal pipe body 110.

[0063] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
