Detailed Implementation

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] Currently, cigarettes are produced using cigarette rolling machines. The exit height of the cigarette rolling machine is relatively high. The cigarettes are usually fed from the cigarette rolling machine by operators who need to catch the cigarette material at a high altitude, then carry the cigarette material to a designated location and then lower it down. This operation results in cigarette scattering and low feeding efficiency.

[0024] Please see Figure 1To address the aforementioned problems, this application provides a feeding device 100, which includes a conveying mechanism 1 and a sorting mechanism 2. The conveying mechanism 1 includes a conveying channel 12, a guiding component 13, and a blocking component 14. The conveying channel 12 includes a first end 121 and a second end 122 along its length. The first end 121 is used to receive materials. The blocking component 14 is located within the conveying channel 12. The guiding component 13 drives the blocking component 14 to move between the first end 121 and the second end 122 of the conveying channel 12. The blocking component 14 has a closed state for blocking materials and an open state for allowing materials to pass through. The sorting mechanism 2 includes a receiving body 21 and a material sorting unit 22. The receiving body 21 has a receiving cavity communicating with the second end 122 of the conveying channel 12. The material sorting unit 22 is located within the receiving cavity and is used to arrange and sort the materials entering the receiving cavity. It is understood that the first end 121 of the conveying channel 12 of the conveying mechanism 1 can receive the material output from the outlet of the cigarette machine 200, and the baffle assembly 14 in the conveying channel 12 is in a closed state, which can support the material input at the first end 121. The guide assembly 13 drives the baffle assembly 14 to move towards the second end 122, thereby conveying the material to the second end 122. Then, the baffle assembly 14 is in an open state, thereby releasing the material into the receiving body 21 of the sorting mechanism 2, and the material sorting unit 22 of the receiving body 21 can arrange and sort the material. Thus, the feeding device 100 of this embodiment can complete the receiving, conveying and feeding of high-altitude cigarette materials. By setting the conveying channel 12 and the baffle assembly 14, the cigarette materials can be confined within a certain space, which can reduce the scattering of cigarette materials; by setting the guide assembly 13, the cigarette materials can be transferred, which improves the conveying efficiency of cigarette materials.

[0025] In the embodiments of this application, please refer to Figure 1 , Figure 1 The AA direction is the first direction, which is the horizontal direction. Figure 1 The BB direction is the second direction, which is the vertical direction, and can also be understood as the height direction of the cigarette machine at 200.

[0026] Please see Figure 1In some embodiments, the conveying mechanism 1 further includes a buffer channel 11 for receiving materials. The buffer channel 11 extends along a first direction and is connected to the first end 121 of the conveying channel 12. The conveying channel 12 extends along a second direction, which intersects with the first direction. The buffer channel 11 is connected to the outlet of the cigarette machine 200. The cigarette materials exiting the cigarette machine 200 enter the buffer channel 11 and gradually accumulate. Since the cigarette machine 200 produces cigarette materials in batches and quantities, the buffer channel 11 can store a batch of cigarette materials. Combined with the conveying channel 12, it can realize the batch feeding of cigarette materials. At the same time, the cigarette materials that do not enter the conveying channel 12 can be temporarily stored in the buffer channel 11, thus increasing the storage capacity of the feeding device 100.

[0027] In an optional implementation, the buffer channel 11 may be a conveying pipe, conveyor belt, conveyor trough, etc.

[0028] In an optional embodiment, the conveying channel 12 is a conveying pipe. The shape of the conveying channel 12 extending along the second direction can be a straight line, a curve, or a spiral, etc.

[0029] In some embodiments, the buffer channel 11 includes a third end 111 and a fourth end 112 along its length. The third end 111 is used to receive materials, and the fourth end 112 is connected to the first end 121 of the conveying channel 12. The conveying mechanism 1 also includes a position sensor 15, which is electrically connected to the guide assembly 13. The position sensor 15 is located within the buffer channel 11 and is positioned close to the fourth end 112. It is understood that cigarette materials gradually accumulate within the buffer channel 11 and move to the fourth end 112 of the buffer channel 11. The fourth end 112 is connected to the first end 121 of the conveying channel 12, meaning the cigarette materials gradually move to the baffle assembly 14 at the first end 121 and accumulate there. The position sensor 15, positioned close to the fourth end 112, can detect the cigarette materials there and, through the control system, move the guide assembly 13, causing the guide assembly 13 to move the baffle assembly 14 towards the second end 122 of the conveying channel 12, thus transferring the cigarette materials. The position sensor 15 enables the guide assembly 13 to promptly transfer the cigarette material conveyed by the conveying channel 12.

[0030] In an optional implementation, the position sensor 15 may be an inductive proximity switch or a capacitive proximity switch.

[0031] In an optional implementation, the guide assembly 13 may be a ball screw linear module, a synchronous belt pulley linear module, a gear and rack linear module, etc.

[0032] Please see Figure 1 and Figure 2In some embodiments, the guide assembly 13 includes a support member 131 and a drive member 132. The support member 131 is connected to the conveying channel 12, and the drive member 132 is connected to the support member 131 and the stop assembly 14. The drive member 132 is used to drive the stop assembly 14 to move between the first end 121 and the second end 122 of the conveying channel 12. The support member 131 can support the drive member 132 and the stop assembly 14. In optional embodiments, the drive assembly can be driven by a motor screw assembly or by a motor synchronous pulley assembly, etc.

[0033] Please see Figure 2 In some embodiments, the driving component 132 includes a drive motor 1321, a lead screw 1322, and a slide 1323. One end of the lead screw 1322 is connected to the support component 131, and the other end is connected to the output shaft of the drive motor 1321. The slide 1323 is driven by the lead screw 1322 and is connected to the stop assembly 14. The drive motor 1321 drives the lead screw 1322 to rotate, and the slide 1323 is driven by the lead screw 1322, converting the rotational motion of the lead screw 1322 into the linear motion of the slide 1323. This causes the slide 1323 to slide along the lead screw 1322, and the slide 1323 drives the stop assembly 14 to move between the first end 121 and the second end 122 of the output channel. Using the lead screw 1322 and the slide 1323 to drive the stop assembly 14 results in high transmission efficiency, high rigidity and stability, and the ability to withstand large radial and axial loads while maintaining stable movement.

[0034] Please see Figure 1 In an optional embodiment, the material blocking assembly 14 may be a gate, a tilting baffle, a telescopic baffle, or the like.

[0035] Please see Figure 1 In some embodiments, the material blocking assembly 14 includes a drive member 141 and a material blocking member 142 located within the conveying channel 12. The drive member 141 is connected to the guide assembly 13, and the drive member 141 drives the material blocking member 142 to rotate relative to the conveying channel 12 to form a closed state that blocks material and an open state that allows material to pass through. The drive member 141 causes the material blocking member 142 to rotate within the conveying channel 12, resulting in a compact structure and improved space utilization.

[0036] In an alternative embodiment, the stop 142 may be flipped toward the first end 121 of the conveying channel 12 or toward the second end 122 of the conveying channel 12.

[0037] Please see Figure 1In some embodiments, the driving member 141 includes a first driver 1411 and a second driver 1412, the blocking member 142 includes a first blocking member 1421 and a second blocking member 1422, and the guiding assembly 13 includes a first guiding assembly 133 and a second guiding assembly 134. The first guiding assembly 133 and the second guiding assembly 134 are respectively disposed on both sides of the conveying channel 12. The first driver 1411 is connected to the first guiding assembly 133 and is driven to the first blocking member 1421. The second driver 1412 is connected to the second guiding assembly 134 and is driven to the second blocking member 1422. The first driver 1411 is used to drive the first blocking member 1421 to flip, and the second driver 1412 is used to drive the second blocking member 1422 to flip. The first blocking member 1421 and the second blocking member 1422 are combined to form a closed state that blocks the material, or the first blocking member 1421 and the second blocking member 1422 are moved away from each other to form an open state that allows the material to pass through. By setting up a reversible first stop 1421 and a second stop 1422, the material release speed can be increased. The material can enter the sorting mechanism 2 under the guidance of the first stop 1421 or under the guidance of the second stop 1422, which makes the material feeding smoother.

[0038] Please see Figure 1 and Figure 2 In an optional embodiment, the first guide assembly 133 includes a support component 131 and a drive component 132. The drive component 132 includes a drive motor 1321, a lead screw 1322, and a slide 1323. The slide 1323 is connected to the first driver 1411 and the first stop component 1421.

[0039] Please see Figure 1 and Figure 2 In an optional embodiment, the second guide assembly 134 includes a support component 131 and a drive component 132. The drive component 132 includes a drive motor 1321, a lead screw 1322, and a slide 1323. The slide 1323 is connected to the second driver 1412 and the second stop component 1422.

[0040] Please see Figure 1 In some embodiments, the sorting mechanism 2 further includes a separator 23 disposed within the receiving cavity to divide the cavity into a first flow channel 24 and a second flow channel 25. Along the height direction of the receiving body 21, the first flow channel 24 and the second flow channel 25 are located at the top of the material sorting unit 22. The separator 23 in the sorting structure can guide materials to the first flow channel 24 and the second flow channel 25 respectively, allowing the accumulated materials to be sorted and diverted, thereby improving the sorting efficiency of the material sorting unit 22.

[0041] Please seeFigure 1 In some embodiments, the receiving body 21 includes a first part 211 and a second part 212 connected to each other, forming a receiving cavity. The first part 211 is connected to the conveying channel 12. A separator 23 is disposed in the first part 211, dividing it into a first flow channel 24 and a second flow channel 25. A material sorting unit 22 is disposed in the second part 212. The cross-sectional area of ​​the first part 211 gradually increases from the conveying channel 12 towards the second part 212. In other words, the first part 211 is a receiving cavity that is narrower at the top and wider at the bottom, with the cavity wall of the first part 211 being a slope. Guided by the slope, it is easier for materials to enter the first flow channel 24 and the second flow channel 25. At the same time, because the cross-sectional area of ​​the first part 211 gradually increases, the material sorting unit 22 has sufficient area to contact the materials, thereby improving the sorting efficiency of the material sorting unit 22.

[0042] Please see Figure 1 In an optional embodiment, when both the first baffle 1421 and the second baffle 1422 move to the second end 122 of the conveying channel 12, the first baffle 1421 can be flipped to abut the cavity wall of the first part 211 of the receiving body 21, and the second baffle 1422 can be flipped to abut the cavity wall of the second part 212 of the receiving body 21, which facilitates the entry of materials into the material sorting unit 22.

[0043] Please see Figure 1 In some embodiments, the material sorting unit 22 includes a plurality of combing needles 221, all of which are spaced apart. The combing needles 221 can disperse and sort the material, so that the cigarettes are arranged parallel to the combing needles 221.

[0044] In other alternative embodiments, the material sorting unit 22 may be a comb plate, a vibratory plate, a guide block, etc.

[0045] The working principle of the feeding device 100 of this application will be specifically described below with reference to specific embodiments:

[0046] Please see Figure 1 and Figure 2The third end 111 of the buffer channel 11 receives cigarette material from the outlet of the cigarette machine. The cigarette material gradually accumulates in the buffer channel 11 and moves to the fourth end 112 of the buffer channel 11 and the first end 121 of the conveying channel 12. The first stop 1421 and the second stop 1422 located at the first end 121 of the conveying channel 12 support the cigarette material. The position sensor 15 detects the cigarette material accumulated at the fourth end 112 and controls the drive motor 1321 of the guide components 13 on the left and right sides of the conveying channel 12 to drive the first driver 1411, the first stop 1421, the second driver 1412, and the second stop 1422 toward the second end 122 through the lead screw 1322 and the slide table 1323. When the material reaches the second end 122 of the conveying channel 12, the first driver 1411 drives the first stop 1421 to flip, and the second driver 1412 drives the second stop 1422 to flip, so that the first driver 1411 and the second driver 1412 are relatively far apart from each other and are in the open state. The cigarette material is released into the first part 211 of the receiving body 21 of the sorting mechanism 2. Under the guidance of the inclined cavity wall and the separator 23 of the first part 211, the material enters the first flow channel 24 and the second flow channel 25 respectively, and enters the material sorting unit 22 of the second part 212 from the first flow channel 24 and the second flow channel 25, where it is sorted by the combing needles 221.

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

[0050] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
