Description

Technical Field

[0002] In cigarette production, a filter rod conveying device includes a filter rod emitter, a filter rod conveying pipeline and a filter rod receiving station. The filter rod is blown to the filter rod receiving station through the filter rod conveying pipeline by compressed air at the filter rod emitter end.

[0003] During the conveying process of the filter rod, the filter rod may be blocked due to reasons such as being horizontal, squeezed and deformed, or the belt of the filter rod receiving station slipping or falling off. After the filter rod is blocked, the receiving station stops running and sends a signal to the emitter to stop the filter rod emission. However, before that, the filter rods that have already entered the conveying pipeline continue to move forward under the action of inertia and compressed air, resulting in a large number of filter rods being blocked in the pipeline. If the defective filter rods in the conveying pipeline are not discharged in time before restarting, it is very easy to cause the filter rod receiving station to be blocked again. Therefore, the operator will unplug the filter rod conveying pipeline for dredging operations. The dredging operations are carried out above the cigarette machine, which has great potential safety hazards. Moreover, the dredging operations require multiple forward and reverse air blows on the filter rod conveying pipeline using compressed air, which not only has a high labor intensity but also has a low dredging efficiency.

[0035] The following will be combined with Figures 1 - 3 and further illustrate the technical solution of the present utility model through specific implementation manners.

[0036] In cigarette production, the filter rod conveying equipment includes a filter rod emitter, a filter rod conveying pipeline and a filter rod receiving station. The filter rod is blown through the filter rod conveying pipeline to the filter rod receiving station by compressed air at the filter rod emitter end. During the conveying process, the filter rod may be horizontal, squeezed and deformed, or the filter rod receiving station belt may slip or fall off, etc., which may cause the filter rod to be blocked. Before restarting the machine, in order to ensure the normal operation of the filter rod conveying equipment, it is necessary to timely discharge the filter rods with quality defects in the conveying pipeline. Therefore, the operator will unplug the filter rod conveying pipeline for dredging operations. The dredging operations are carried out above the cigarette machine, which has relatively large safety hazards and low dredging operation efficiency.

[0037] To solve the above problems, an embodiment of the present utility model provides a filter rod conveying device, which includes a filter rod transmitter, a filter rod conveying pipeline, a filter rod receiving station, and two filter rod dredging devices. The filter rod dredging device includes a fixed component 1 and a movable member 2. The fixed component 1 is provided with a first connection hole 121 and a first half groove 111. The first half groove 111 communicates with the first connection hole 121, and the first connection hole 121 is used for introducing compressed air. The movable member 2 is provided with a second half groove 21. The movable member 2 is slidably matched with the fixed component 1, and the movable member 2 has a first position and a second position relative to the fixed component 1. The first position is that the fixed component 1 abuts against the movable member 2, and the first half groove 111 and the second half groove 21 enclose a filter rod channel. The second position is that the fixed component 1 and the movable member 2 are spaced apart. When the movable member 2 is in the first position, the filter rod dredging device normally conveys the filter rod or the compressed air device introduces compressed air into the filter rod channel. When the movable member 2 is in the second position, the movable member 2 moves away from the fixed component 1, and the filter rod dredging device discharges the blocked filter rod in the filter rod conveying pipeline. This device avoids the safety hazards of the operator performing dredging operations above the cigarette machine, and has a simple structure, convenient operation, and improves the dredging operation efficiency.

[0038] Specifically, one end of the filter rod channel on one of the filter rod dredging devices close to the first connection hole 121 is communicated with the emission pipeline of the filter rod transmitter, and the other end of the filter rod channel is communicated with one end of the filter rod conveying pipeline. One end of the filter rod channel on the other filter rod dredging device close to the first connection hole 121 is communicated with the receiving pipeline of the filter rod receiving station, and the other end of the filter rod channel is communicated with the other end of the filter rod conveying pipeline. When the filter rod conveying device operates normally, the movable member 2 is in the first position, and the filter rod is emitted from the filter rod transmitter end and sent to the filter rod receiving station through the filter rod channel and the filter rod conveying pipeline. When the filter rod is blocked, when the filter rod conveying pipeline on the side close to the filter rod receiving station is blocked, the filter rod dredging device at the end close to the filter rod transmitter introduces compressed air into the filter rod conveying pipeline through the first connection hole 121. At the same time, the movable member 2 of the filter rod dredging device at the filter rod receiving station end moves from the first position to the second position, and the movable member 2 moves away from the fixed component 1. The blocked filter rod in the filter rod conveying pipeline is discharged from the filter rod dredging device at the filter rod receiving station end under the action of the compressed air. When the filter rod conveying pipeline on the side close to the filter rod transmitter is blocked, the filter rod dredging device at the end close to the filter rod receiving station introduces compressed air into the filter rod conveying pipeline through the first connection hole 121. At the same time, for the filter rod dredging device at the filter rod transmitter end, the movable member 2 moves from the first position to the second position, and the movable member 2 moves away from the fixed component 1. The blocked filter rod in the filter rod conveying pipeline is discharged from the filter rod dredging device at the filter rod transmitter end under the action of the compressed air.

[0039] In this embodiment, the fixing component 1 includes a fixing member 11 and a connecting member 12. The first half groove 111 is provided on the fixing member 11. One end of the fixing member 11 is provided with a first through hole, and the first through hole communicates with the first half groove 111. One end of the connecting member 12 is inserted into the first through hole. The first connection hole 121 is provided on the connecting member 12. The connecting member 12 is provided with a second through hole 122, and the first connection hole 121 communicates with the second through hole 122. The other end of the connecting member 12 communicates with the emission pipeline of the filter rod transmitter or the receiving pipeline of the filter rod receiving station. This setting facilitates the processing of the fixing component 1 and also facilitates the connection of the filter rod conveying device to other pipelines.

[0040] Further, the first connection hole 121 communicates with one end of the filter rod channel, and the axis of the first connection hole 121 forms an obtuse angle with the axis of the filter rod channel, which can enable the compressed air to flow better into the filter rod conveying pipeline.

[0041] Optionally, the filter rod dredging device further includes a first joint 4. One end of the first joint 4 is inserted into the first connection hole 121, and the other end is connected to the compressed air equipment. Through the first joint 4, the filter rod channel can be directly communicated with the compressed air pipeline of the compressed air equipment, which is convenient to operate and has better sealing performance during the process of introducing compressed air.

[0042] As Figure 1 shown, in order to prevent residual filter rods from existing in the filter rod channel after dredging, in this embodiment, the fixing component 1 is provided with a second connection hole 112. The second connection hole 112 is provided on one side of the fixing member 11, and the second connection hole 112 communicates with the first half groove 111. Compressed air is introduced through the second connection hole 112 to blow the inside of the device, so as to avoid the filter rod channel being blocked by filter rods. Optionally, in this embodiment, the number of the second connection holes 112 is two, and the two second connection holes 112 are arranged on the fixing member 11 at intervals.

[0043] As Figure 2 and Figure 3 shown, when the movable member 2 is in the first position, the movable member 2 abuts against the fixing member 11. Optionally, one of the fixing member 11 and the movable member 2 is provided with a sliding groove 113, and the other is provided with a guiding block 22. The guiding block 22 slides in the sliding groove 113, so as to realize the sliding fit between the fixing member 11 and the movable member 2, ensuring the accuracy of the reset of the movable member 2 when it moves from the second position to the first position. Exemplarily, the sliding groove 113 is provided on the fixing member 11 and the guiding block 22 is provided on the movable member 2, or the sliding groove 113 is provided on the movable member 2 and the guiding block 22 is provided on the fixing member 11. Further, the guiding block 22 is set to be V-shaped at the end where the fixing member 11 and the movable member 2 are close to each other, further ensuring the accuracy of the reset of the movable member 2.

[0044] In this embodiment, the fixing member 11 includes a first long arm and a second short arm. The first long arm and the second short arm are arranged in an L shape. The movable member 2 includes a second long arm and a second short arm. The second long arm and the second short arm are arranged in an L shape. When the movable member 2 is in the first position, the first long arm is in contact with the second long arm, the second short arm abuts against the first long arm along the axial direction of the filter rod channel, and the second long arm abuts against the first short arm along the axial direction of the filter rod channel, thereby restricting the axial movement of the movable member 2 along the filter rod channel and ensuring the stability of the device during the dredging operation.

[0045] As Figure 2 shown, the filter rod dredging device further includes a driving member 3. The driving member 3 can drive the movable member 2 to slide relative to the fixing assembly 1 between the first position and the second position. When a filter rod is blocked in the filter rod conveying pipeline, the driving member 3 can be directly started, thereby driving the movable member 2 to move, so that the movable member 2 moves from the first position to the second position. After the blocked filter rod is removed, the driving member 3 drives the movable member 2 to move from the second position to the first position, ensuring the accuracy of the position of the movable member 2 and further improving the dredging operation efficiency of the device.

[0046] Optionally, in this embodiment, the driving member 3 is a cylinder, which has a simple structure and is easy to install and maintain. The cylinder body of the cylinder is arranged on the fixing member 11, and the piston rod passes through the fixing member 11 and is fixedly connected to the movable member 2. The piston rod drives the movable member 2 to perform reciprocating motion to realize the switching of the movable member 2 between the first position and the second position.

[0047] In this embodiment, the filter rod dredging device further includes a air pressure detection component 5, which is arranged at one end of the filter rod channel away from the first connection hole 121 and can detect the internal air pressure of the filter rod channel, so as to determine whether the dredging work is completed. Optionally, the air pressure detection component 5 adopts an air pressure detection sensor, which has high precision and fast response. Specifically, when the filter rod is normally transported, it is set that the pressure detected by the air pressure detection sensor at the filter rod transmitter end is P1, and the pressure detected by the air pressure detection sensor at the filter rod receiving station end is P2, where P2 < P1. Taking the dredging operation of the filter rod conveying pipeline near the filter rod receiving station end being blocked as an example: the filter rod dredging device at the filter rod transmitter end is connected to compressed air to blow the filter rod conveying pipeline, and at the same time, the moving part 2 in the filter rod dredging device at the filter rod receiving station end moves to the second position to discharge the blocked filter rod. The pressure detected by the air pressure detection sensor at the filter rod receiving station end is P. If P2 < P < P1, the filter rod conveying pipeline has been dredged; if P is not within this range, the filter rod conveying pipeline has not been dredged and is still blocked, then reverse dredging is carried out. The filter rod dredging device at the filter rod receiving station end is connected to compressed air to blow the filter rod channel, and at the same time, the moving part 2 in the filter rod dredging device at the filter rod transmitter end moves to the second position to discharge the blocked filter rod. At this time, the pressure detected by the air pressure detection sensor at the filter rod receiving station end is P0. If P2 < P0 < P1, the filter rod conveying pipeline has been dredged.

[0048] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
