Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, in particular to a filter rod pipeline cleaning device and a filter rod conveying device. Background Art

[0002] In cigarette production, the filter rod conveying device includes a filter rod transmitter, a filter rod conveying pipeline and a filter rod receiver. The filter rod is blown through the filter rod conveying pipeline to the filter rod receiver by compressed air at the filter rod transmitter end. The filter rod conveying pipeline is an important part in filter rod conveying. In the workshop layout, the filter rod conveying pipeline is long and has many turns. When the filter rod is conveyed in the pipeline, it will be affected by the frictional force of the pipe wall on the filter rod, the lateral pressure of the pipe wall on the filter rod during turning, the resistance of the pipeline connection to the front end of the filter rod, the obstruction of the sediment in the pipeline to the filter rod, etc., resulting in phenomena such as the end of the filter rod touching the head, the forming paper being damaged, and the filter rod being bent in the conveying pipeline, leading to the blockage of the filter rod. However, when the filter rod is blocked in the pipeline, the transmitter end will not immediately stop the filter rod emission and conveying. After the filter rod enters the conveying pipeline, it directly hits the blockage point. After the filter rod is squeezed front and back, it will cause serious deformation and even further aggravate the blockage. Moreover, the sediment will increase continuously with the use time of the pipeline, thereby increasing the probability of filter rod blockage. After the filter rod is blocked, the operator will pull out the filter rod conveying pipeline and use compressed air to blow the filter rod conveying pipeline back and forth many times for dredging. Even the operator needs to check the filter rod conveying pipeline section by section and disassemble the pipeline for dredging and cleaning. This not only has a large labor intensity but also has a low dredging operation efficiency. Content of the Utility Model

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0039] The following will be combined with Figures 1 - 7 and further illustrate the technical solutions of the present utility model through specific embodiments.

[0040] In cigarette production, the filter rod conveying equipment includes a filter rod transmitter, a filter rod conveying pipeline, and a filter rod receiver. The filter rods are sent to the filter rod receiver through the filter rod conveying pipeline by compressed air at the filter rod transmitter end. During the conveying process, the filter rods are subject to the frictional force of the pipe wall on the filter rods, the lateral pressure of the pipe wall on the filter rods during turning, the resistance of the pipe joint to the front end of the filter rods, and the obstruction of the filter rods by the deposits in the pipeline, etc., resulting in phenomena such as the end contact of the filter rods, the damage of the forming paper, and the bending of the filter rods in the conveying pipeline, causing blockage of the filter rods in the filter rod conveying pipeline.

[0041] To solve the above problems, as Figure 1 and Figure 2 shown, an embodiment of the present invention provides a filter rod conveying equipment, which includes a filter rod transmitter, a filter rod conveying pipeline, a filter rod receiver, and two filter rod pipeline cleaning devices. One end of the filter rod conveying channel 11 of one of the filter rod pipeline cleaning devices is connected to the transmitting pipeline of the filter rod transmitter, and the second connection port 212 and the fifth connection port 222 are selectively connected to one end of the filter rod conveying pipeline. One end of the filter rod conveying channel 11 of the other filter rod pipeline cleaning device is connected to the receiving pipeline of the filter rod receiver, and the second connection port 212 and the fifth connection port 222 are selectively connected to the other end of the filter rod conveying pipeline.

[0042] Among them, the filter rod pipeline cleaning device includes a guiding component 1 and a connecting component 2. The guiding component 1 is provided with a filter rod conveying channel 11 and a blocked filter rod discharge channel 12. One end of the filter rod conveying channel 11 is connected to the transmitting pipeline of the filter rod transmitter or the receiving pipeline of the filter rod receiver; the connecting component 2 includes a first connecting component 21 and a second connecting component 22. The first connecting component 21 includes a first connection port 211, a second connection port 212, and a third connection port 213. The first connection port 211 is connected to the other end of the filter rod conveying channel 11. Both the first connection port 211 and the third connection port 213 are connected to the second connection port 212. The third connection port 213 is used to access compressed air so that the compressed air flows into the filter rod conveying pipeline; the second connecting component 22 includes a fourth connection port 221, a fifth connection port 222, and a sixth connection port 223. The fourth connection port 221 is connected to both the fifth connection port 222 and the sixth connection port 223. The fourth connection port 221 is connected to one end of the blocked filter rod discharge channel 12. The second connection port 212 and the fifth connection port 222 are selectively connected to the filter rod conveying pipeline. The sixth connection port 223 is used to access compressed air, and the compressed air flows into the blocked filter rod discharge channel 12.

[0043] Specifically, the filter rod dredging equipment has two working states, namely the normal filter rod conveying state and the state of cleaning blocked filter rods. As Figure 3As shown, the filter rod conveying channel 11 is used to convey filter rods when the filter rod pipeline cleaning device is working properly, and the blocked filter rod discharge channel 12 is used to discharge the blocked filter rods in the filter rod conveying pipeline. In this embodiment, both ends of the filter rod conveying channel 11 are at the same height, which is conducive to the normal conveyance of filter rods. Along the direction from one end of the filter rod conveying channel 11 to the other end, the blocked filter rod discharge channel 12 deviates away from the filter rod conveying channel 11, that is, the blocked filter rod discharge channel 12 is inclined, so that the blocked filter rods can be discharged more easily. Moreover, the diameter of the blocked filter rod discharge channel 12 is larger than that of the filter rod conveying channel 11, which is more conducive to the discharge of the squeezed and deformed filter rods after being blocked.

[0044] When the filter rods are conveyed normally, the second connection ports 212 of the two filter rod pipeline cleaning devices are respectively connected to one end of the filter rod conveying pipeline. The filter rods are emitted by the filter rod transmitter and sent to the filter rod receiver through the filter rod conveying channel 11 of the filter rod pipeline cleaning device and the filter rod conveying pipeline.

[0045] When the filter rod conveying pipeline near the filter rod receiver is blocked, the second connection port 212 in the filter rod pipeline cleaning device near the filter rod transmitter end is communicated with one end of the filter rod conveying pipeline, and compressed air is introduced through the third connection port 213 at this end. The fifth connection port 222 in the filter rod pipeline cleaning device near the filter rod receiver end is communicated with the other end of the filter rod conveying pipeline, and compressed air is introduced through the sixth connection port 223 at this end. The compressed air at the third connection port 213 blows the blocked filter rods and sediments in the filter rod conveying pipeline. The compressed air at the sixth connection port 223 causes a pressure difference between one end of the fourth connection port 221 and one end of the fifth connection port 222. The pressure at the fifth connection port 222 end is less than the pressure at the fourth connection port 221 end, so as to generate a negative pressure to suck the blocked filter rods in the filter rod conveying pipeline. By setting the filter rod management and cleaning device, the front end of the blocked filter rod is quickly loosened under the action of the negative pressure, reducing the degree of filter rod blockage. Together with the compressed air acting on the rear end of the filter rod, the blocked filter rods are quickly discharged from the blocked filter rod discharge channel 12. By blowing and sucking the blocked filter rods with compressed air at the same time, the dredging operation is efficient and reliable. Moreover, during the dredging process, the filter rod conveying pipeline can also be blown to clean the inside of the pipeline and prevent sediment accumulation from causing filter rod blockage.

[0046] When the filter rod conveying pipeline near the filter rod transmitter is blocked, the second connection port 212 in the filter rod pipeline cleaning device near the filter rod receiver end is communicated with one end of the filter rod conveying pipeline, and the fifth connection port 222 in the filter rod pipeline cleaning device near the filter rod transmitter end is communicated with the other end of the filter rod conveying pipeline. The process of unblocking the blocked filter rods is the same as that in the case near the filter rod receiver side, which will not be elaborated here.

[0047] Further, during the process of unclogging the filter rod, compressed air is introduced through the sixth connection port 223. The sixth connection port 223 is communicated with the fourth connection port 221, and the compressed air flows rapidly in the direction of the fourth connection port 221. According to Bernoulli's principle, the greater the flow rate, the smaller the pressure. As a result, the pressure at one end of the fourth connection port 221 is less than the pressure at one end of the fifth connection port 222, creating a pressure difference between the two ends. The gas at one end of the fifth connection port 222 flows towards the end of the fourth connection port 221, causing the pressure at the fifth connection port 222 to drop. With the continuous introduction of compressed air, the pressure continues to drop, thereby generating a negative pressure to suck the clogged filter rod in the filter rod conveying pipeline into the clogged filter rod discharge channel 12 and discharging it. It should be noted that Bernoulli's principle is a prior art and will not be elaborated here.

[0048] As Figure 5 shown, the second connector 22 is provided with a channel. The fourth connection port 221 is arranged at one end of the channel, and the fifth connection port 222 is arranged at the other end of the channel. The second connector 22 is provided with an annular cavity 224. The annular cavity 224 is sleeved on the channel, and the annular cavity 224 is communicated with the sixth connection port 223. The second connector 22 is provided with a plurality of first through holes 2241. The plurality of first through holes 2241 are arranged on the side of the annular cavity 224 close to the fourth connection port 221. The first through holes 2241 communicate the annular cavity 224 with the fourth connection port 221. Compressed air flows into the annular cavity 224 from the sixth connection port 223 and then flows towards the fourth connection port 221 through the plurality of first through holes 2241. The arrangement of the plurality of first through holes 2241 makes the flow rate of the compressed air greater, thereby enabling the generation of a negative pressure at the fifth connection port 222 end faster to suck the clogged filter rod. Further, the plurality of first through holes 2241 are evenly distributed around the axis of the channel, so that the compressed air flows uniformly towards the fourth connection port 221, and thus the negative pressure generated in the filter rod conveying pipeline is relatively uniform, which is more conducive to the discharge of the clogged filter rod.

[0049] Further, a guiding surface 225 is arranged on the inner wall of the channel. The guiding surface 225 faces the plurality of first through holes 2241, and the guiding surface 225 can guide the flow direction of the compressed air so that the compressed air flows into the fourth connection port 221 through the guiding surface 225. Specifically, the guiding surface 225 encloses a conical hole. The small-diameter end of the conical hole is communicated with the fourth connection port 221, and the large-diameter end is opposite to the annular cavity 224.

[0050] Further, as Figure 6 and Figure 7As shown, for the convenience of processing the plugging filter rod discharge channel 12, the guiding assembly 1 is provided as a split type, which includes a guiding block 13 and a guiding block cover plate 14. The guiding block cover plate 14 is arranged on the guiding block 13. A first half groove 131 is provided on the guiding block 13, and a second half groove 141 is provided on the guiding block cover plate 14. The first half groove 131 and the second half groove 141 enclose to form the plugging filter rod discharge channel 12. The first half groove 131 and the second half groove 141 are processed separately, and then the guiding block cover plate 14 and the guiding block 13 are fixedly connected, and thus the plugging filter rod discharge channel 12 can be formed, which is convenient for processing and has low cost.

[0051] Specifically, a notch is provided on the guiding block 13, and the guiding block cover plate 14 is accommodated in the notch. The side wall of the guiding block cover plate 14 abuts against the side wall of the notch, which can play an anti-misalignment role for the installation of the guiding block cover plate 14, and then the guiding block cover plate 14 and the guiding block 13 are fixedly connected by fasteners. Further, a first connection hole 132 and a second connection hole 133 are provided on the guiding block 13. One end of the first connection port 211 on the first connecting member 21 is inserted into the first connection hole 132, and the first connection hole 132 communicates with the filter rod conveying channel 11. One end of the fourth connection port 221 on the second connecting member 22 is inserted into the second connection hole 133, and the second connection hole 133 communicates with the plugging filter rod discharge channel 12, which also makes the installation of the first connecting member 21 and the second connecting member 22 more convenient.

[0052] In order to ensure the stability of the filter rod pipeline cleaning device, in this embodiment, the filter rod pipeline cleaning device further includes a base 3. The base 3 is provided with a receiving cavity. A second through hole 31 is provided on the side wall of the receiving cavity. One end of the second through hole 31 communicates with the filter rod conveying pipeline. The guiding assembly 1 is slidably arranged in the receiving cavity and has a first position and a second position relative to the base 3. The first position is that the second connection port 212 communicates with the other end of the second through hole 31, and the second position is that the fifth connection port 222 communicates with the other end of the second through hole 31. The guiding assembly 1 is slidably arranged on the base 3. When the filter rod is blocked, the second connection port 212 on the filter rod pipeline cleaning device communicates with the second through hole 31 and can be immediately switched to the fifth connection port 222 communicating with the second through hole 31, that is, the guiding assembly 1 is switched from the first position to the second position, and then the dredging operation is carried out. After the blocked filter rod is removed, the guiding assembly 1 is switched from the second position to the first position, that is, the second connection port 212 is communicated with the second through hole 31 to carry out the normal conveyance of the filter rod.

[0053] Specifically, when the filter rod conveying pipeline on the side close to the filter rod receiver is blocked, the guiding component 1 in the filter rod pipeline cleaning device at one end close to the filter rod transmitter is in the first position, and compressed air is introduced into the third connection port 213 in the filter rod pipeline cleaning device at this end to blow the filter rod conveying pipeline. The guiding component 1 in the filter rod pipeline cleaning device close to the filter rod receiver end switches to the second position, and compressed air is introduced into the sixth connection port 223 in the filter rod pipeline cleaning device at this end; when the filter rod conveying pipeline on the side close to the filter rod transmitter is blocked, the guiding component 1 in the filter rod pipeline cleaning device at one end close to the filter rod receiver is in the first position, and compressed air is introduced into the third connection port 213 in the filter rod pipeline cleaning device at this end to blow the filter rod conveying pipeline. The guiding component 1 in the filter rod pipeline cleaning device close to the filter rod transmitter end switches to the second position, and compressed air is introduced into the sixth connection port 223 in the filter rod pipeline cleaning device at this end.

[0054] Furthermore, a third through hole 32 is also provided on the base 3. The third through hole 32 is arranged on the side wall of the accommodating cavity and is opposite to the side wall where the second through hole 31 is located. One end of the third through hole 32 is communicated with the transmitting pipeline of the filter rod transmitter or the receiving pipeline of the filter rod receiver, and the other end is communicated with the filter rod conveying channel 11. When in the first position, the filter rod conveying channel 11 is opposite to and communicated with the other end of the third through hole 32. Through the third through hole 32, support can be provided for the transmitting pipeline of the filter rod transmitter or the receiving pipeline of the filter rod receiver, improving the stability of the base 3. Furthermore, a fourth through hole 33 is also provided on the side wall of the accommodating cavity where the third through hole 32 is located. One end of the fourth through hole 33 is communicated with the blocked filter rod discharge channel 12 for discharging the blocked filter rods.

[0055] The filter rod pipeline cleaning device further includes a driving member 4. The driving member 4 can drive the guiding component 1 to switch between the first position and the second position relative to the base 3. When the filter rods in the filter rod conveying pipeline are blocked, the driving member 4 can be directly started, thereby driving the guiding component 1 to act, so that the guiding component 1 moves from the first position to the second position. After the blocked filter rods are removed, the driving member 4 drives the guiding component 1 to move from the second position to the first position, ensuring the accuracy of the position of the guiding component 1 and further improving the dredging operation efficiency of the device.

[0056] Optionally, the driving member 4 is a cylinder, which has a simple structure and is easy to install and maintain. Preferably, a double-guide rod cylinder is used. The cylinder body of the double-guide rod cylinder is arranged outside the base 3, and the guide rods are fixedly connected to the guiding component 1. The guiding component 1 is driven to reciprocate through the guide rods, realizing the switching of the guiding component 1 between the first position and the second position. The double-guide rod cylinder has good stability and can effectively ensure the smooth sliding of the guiding component 1 relative to the base 3 and the accurate movement.

[0057] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
