Description

Technical Field

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

[0002] A feeding bin is a tobacco feeding device and one of the important auxiliary equipment in the tobacco processing workshop of a tobacco company. Its main function is to buffer materials and work with electronic belt scales and metering tubes to stabilize the material flow in subsequent processes. It is an essential pre-processing device in each process section of the tobacco processing line. Its structure generally includes a storage mechanism and a lifting mechanism.

[0003] During actual production, there is some material adhesion and leakage at the straight conveyor belt of the storage mechanism and the inclined belt of the lifting mechanism, as well as at their connection point. A large amount of residual tobacco leaves (or shredded tobacco) remains in the receiving box at the bottom of the feeding hopper. According to the cigarette quality process requirements, after each batch of tobacco leaves is produced, the material in the receiving box must be returned to the current batch to reduce material loss during the tobacco processing and ensure the integrity of the cigarette batch formula.

[0004] Currently, the material recovery process generally relies on manual labor. For example, workers have to manually pull out and clean the receiving box, and then stand on a shared platform to pour the material into the feeding hopper. This material recovery method requires a lot of manual intervention, which not only consumes labor but also increases the safety hazards for operators. Furthermore, it is easy for batches of material to be not mixed back in time, resulting in quality risks of mixed brands and batches.

[0005] Therefore, how to achieve automatic recycling of materials in the receiving box to reduce manpower input and improve recycling efficiency and quality is an urgent problem to be solved in the tobacco industry. Utility Model Content

[0006] The purpose of this invention is to provide a tobacco feeding device that can automatically recycle materials in the receiving box, thereby reducing manpower input and improving recycling efficiency and quality.

[0017] As an optional solution to the above-mentioned tobacco feeding device, the cleaning mechanism includes:

[0018] The brush assembly is movable within the receiving mechanism;

[0019] A drive component, connected to the brush assembly, is used to drive the brush assembly to move relative to the receiving mechanism to sweep the material to the designated position.

[0020] As an alternative to the above-mentioned tobacco feeding device, the brush assembly extends along a first horizontal direction, and the output end of the drive assembly reciprocates along a second horizontal direction, wherein the first horizontal direction and the second horizontal direction are perpendicular.

[0021] As an alternative to the aforementioned tobacco feeding device, the cleaning mechanism further includes a drive protective cover, which is disposed outside the drive assembly.

[0026] As an alternative to the aforementioned tobacco feeding device, the return pipe includes a flexible hose.

[0027] The beneficial effects of this utility model are:

[0028] The tobacco feeding device provided by this utility model uses a receiving mechanism to receive leaked material and a cleaning mechanism to concentrate the material in the receiving mechanism to a designated position. Then, the suction force generated by the negative pressure suction mechanism is used to recover the material at the designated position back to the feeder, realizing automatic recovery of leaked material.

Detailed Implementation

[0035] 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.

[0036] In the description of this utility model, unless otherwise explicitly 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; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] 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.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," 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.

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides a tobacco feeding device, including a frame 10, a feeder 50, a storage mechanism (not shown in the figure), and a lifting mechanism (not shown in the figure). A transmission channel 11 is formed within the frame 10. The storage mechanism includes a straight conveyor belt assembly for transporting materials, and the lifting mechanism includes an inclined lifting belt assembly for transporting materials. The inclined lifting belt assembly transports materials at an angle from bottom to top and can also receive materials transported by the straight conveyor belt. Both the straight conveyor belt assembly and the inclined lifting belt assembly are disposed within the transmission channel 11. When the tobacco feeding device is in operation, the materials released by the feeder 50 are transported sequentially through the straight conveyor belt assembly and the inclined lifting belt assembly.

[0040] It should be noted that both the straight conveyor belt assembly and the inclined belt assembly are belt conveyor assemblies, and their structures are existing technologies in this field, so they will not be described in detail here.

[0041] During the operation of the tobacco feeding device, both the straight conveyor belt assembly and the inclined conveyor belt assembly experience material sticking and leakage during transportation, causing some material to fall into the transmission channel 11. This requires manual cleaning, collection, and recycling, which is labor-intensive, poses safety hazards, and is prone to the phenomenon of not timely mixing of the same batch of material, resulting in quality risks of mixed brands and batches.

[0042] To solve the above problems, such as Figures 1-3 As shown, the tobacco feeding device also includes a receiving mechanism 20, a cleaning mechanism 30, and a negative pressure suction mechanism 40. The receiving mechanism 20 is located below the feeder 50 and is used to receive dropped materials. The cleaning mechanism 30 is connected to the receiving mechanism 20 and is used to collect the materials in the receiving mechanism 20 to a designated location. The negative pressure suction mechanism 40 connects the receiving mechanism 20 and the feeder 50 and is used to transfer the materials in the receiving mechanism 20 to the feeder 50. This tobacco feeding device uses the receiving mechanism 20 to receive spilled materials and the cleaning mechanism 30 to concentrate the materials in the receiving mechanism 20 to a designated location. Then, using the suction force generated by the negative pressure suction mechanism 40, the materials at the designated location are recovered into the feeder 50, achieving automatic recovery of spilled materials. This reduces manual labor, improves recovery efficiency and quality, and avoids the quality risks of untimely material return and mixed brands / batch.

[0043] In some embodiments, the receiving mechanism 20 includes a receiving box 21 and a receiving hopper 22 connected to the receiving box 21. The top of the receiving box 21 is provided with an opening to facilitate the leakage of material into the receiving box 21. The receiving hopper 22 is connected to the negative pressure suction mechanism 40. By concentrating the leakage of material in the receiving hopper 22 and then cooperating with the negative pressure suction mechanism 40 for recycling, the recycling effect of the leakage of material can be improved and material residue can be avoided.

[0044] In some implementations, the cross-sectional area of ​​the receiving hopper 22 gradually decreases from top to bottom, and the bottom end of the receiving hopper 22 is connected to the negative pressure suction mechanism 40 so that the material entering the receiving hopper 22 can move downward under its own gravity, which is beneficial for material recycling.

[0045] In some embodiments, the receiving hopper 22 is located below the receiving box 21 and communicates with the receiving box 21, so as to facilitate the cleaning mechanism 30 to clean and collect the material in the receiving box 21 into the receiving hopper 22.

[0046] In some embodiments, the receiving box 21 has a flat box structure and a large area to ensure that leaked material can fall into the receiving box 21; the receiving box 21 has a shallow depth to reduce the height of the receiving box 21, thereby reducing the space occupied by the receiving box 21 and helping to reduce the overall size of the tobacco feeding device.

[0047] In some embodiments, two receiving hoppers 22 are provided, with one receiving hopper 22 connected to each of the opposite ends of the receiving box 21 to facilitate the collection of leaked material. In other embodiments, the number and location of the receiving hoppers 22 can be set according to actual needs.

[0048] In some embodiments, the bottom height of the receiving box 21 can gradually decrease from the middle to the edge of the receiving hopper 22, thereby guiding the material and facilitating its entry into the receiving hopper 22.

[0049] To facilitate thorough cleaning of the receiving mechanism 20, in some embodiments, the receiving mechanism 20 also includes a traveling wheel assembly 23. The traveling wheel assembly 23 is located at the bottom of the receiving box 21 and can move the position of the receiving box 21 freely, so that the operator can easily pull the receiving box 21 out from under the frame 10 for thorough cleaning of the inside of the receiving box 21.

[0050] In some embodiments, the walking wheel assembly 23 includes a support foot and a walking wheel rotatably disposed at the bottom of the support foot. The support foot is connected to the bottom of the receiving box 21 to raise the receiving box 21, thereby providing installation space for the receiving hopper 22.

[0051] In some embodiments, the wheels can be casters to facilitate the movement of the material receiving mechanism 20.

[0052] To collect the material in the receiving box 21 into the receiving hopper 22, in some embodiments, the cleaning mechanism 30 includes a brush assembly 31 and a drive assembly 32. The brush assembly 31 is movably disposed in the receiving box 21, and the drive assembly 32 is connected to the brush assembly 31 to drive the brush assembly 31 to move relative to the receiving box 21, thereby sweeping the material into the receiving hopper 22 through the movement of the brush assembly 31. This cleaning mechanism 30 has a simple structure, can avoid dust scattering, and has a good cleaning effect.

[0053] In some embodiments, the drive assembly 32 drives the brush assembly 31 to reciprocate linearly to gather the material in the receiving box 21 to the opposite ends of the receiving box 21. The receiving hopper 22 is connected to the bottom end of the receiving box 21 to facilitate the material entering the receiving hopper 22 under the action of the drive assembly 32.

[0054] Optionally, the brush assembly 31 extends along a first horizontal direction, and the output end of the drive assembly 32 reciprocates along a second horizontal direction. The output end of the drive assembly 32 is connected to the brush assembly 31. At least one end of the receiving box 21 along the second horizontal direction is provided with a receiving hopper 22, wherein the first horizontal direction and the second horizontal direction are perpendicular. This arrangement allows the material in the receiving box 21 to be swept into the receiving hopper 22 by the linear motion of the brush assembly 31, thereby achieving material collection.

[0055] For example, the receiving box 21 is a rectangular box, the first horizontal direction is the width direction of the receiving box 21, the second horizontal direction is the length direction of the receiving box 21, the brush assembly 31 extends along the width direction of the receiving box 21, and can move along the length direction of the receiving box 21 under the drive of the drive assembly 32, so as to collect the material in the receiving box 21 into the receiving hopper 22.

[0056] In some embodiments, the brush assembly 31 includes a brush holder and a brush disposed on the brush holder, the brush holder being connected to the drive assembly 32 to drive the brush to move.

[0057] In some embodiments, the drive assembly 32 includes a drive motor 321, a lead screw, and a nut. The drive motor 321 is disposed in the receiving box 21, and its output end is connected to the lead screw to drive the lead screw to rotate. The nut is threadedly engaged with the lead screw and is connected to the brush assembly 31. When the lead screw rotates under the drive of the drive motor 321, the nut moves along the length of the lead screw to drive the brush assembly 31 to move linearly.

[0058] In some embodiments, the drive assembly 32 further includes a mounting base 322, which is disposed on the upper end of the receiving box 21, and the drive motor 321 is disposed on the mounting base 322.

[0059] In other embodiments, the drive assembly 32 may also be a linear motor, cylinder, hydraulic cylinder, rack and pinion drive assembly, or other drive structures capable of outputting linear motion.

[0060] To prevent spilled material from contacting the drive assembly 32 and affecting its normal operation, in some embodiments, the cleaning mechanism 30 further includes a drive protective cover 33. The drive protective cover 33 is placed over the drive assembly 32 to protect the drive assembly 32 and prevent spilled material from affecting its normal operation.

[0061] In some embodiments, the drive protective cover 33 includes a first top cover and a second top cover arranged at an angle, the top ends of the first top cover and the second top cover are connected, and the distance between the first top cover and the second top cover gradually increases from top to bottom so that the drive protective cover 33 forms a sharp angle, and the material falling on the drive protective cover 33 can move downward along the first top cover and the second top cover under the action of gravity to avoid accumulating on the drive protective cover 33.

[0062] In some embodiments, the negative pressure suction mechanism 40 includes a return pipe 41 and a negative pressure generating component 42 connected together. The return pipe 41 is connected to the receiving mechanism 20, and the negative pressure generating component 42 is connected to the feeder 50. The negative pressure generating component 42 can be a blower.

[0063] In some embodiments, the receiving mechanism 20 is connected to the bottom end of the frame 10, and the negative pressure generating component 42 is located at the top end of the frame 10. The return pipe 41 needs to connect the receiving mechanism 20 at the bottom end and the negative pressure generating component 42 at the top end, which causes the return pipe 41 to bend. In order to facilitate the connection between the receiving mechanism 20 and the negative pressure generating component 42, the return pipe 41 includes a flexible hose 411. The flexible hose 411 can bend adaptively, thereby adapting to the overall structure to meet the connection requirements.

[0064] In order to avoid the bending of the return pipe 41 from affecting the return effect, in some embodiments, the hose 411 is a steel hose, so that it has a certain strength while being able to bend, and avoids the hose 411 collapsing and affecting the material transmission while bending.

[0065] In some embodiments, two hoses 411 are provided, with one hose 411 connected to each receiving hopper 22, so that the material in each receiving hopper 22 is recycled into the feeder 50.

[0066] To ensure the effective connection between the return pipe 41 and the negative pressure generating component 42, the return pipe 41 also includes a connecting pipe 412. One end of the connecting pipe 412 is connected to each hose 411, and the other end of the connecting pipe 412 is connected to the negative pressure generating component 42. The connecting pipe 412 can be a rigid pipe to ensure a secure connection with the negative pressure generating component 42.

[0067] In some embodiments, the connecting pipe 412 is a bend so that the flexible hose 411 can extend downward to connect to the receiving hopper 22.

[0068] In some embodiments, the tobacco feeding device further includes a first detection component, which is used to detect the amount of material in the receiving mechanism 20 (specifically, the amount of material in the receiving box 21). The first detection component is communicatively connected to the cleaning mechanism 30. When the first detection component detects that the amount of material in the receiving mechanism 20 reaches a first preset value, the first detection component communicates with the cleaning mechanism 30, and the cleaning mechanism 30 is activated to collect the material in the receiving box 21 into the receiving hopper 22.

[0069] In some embodiments, the first detection component includes a first distance sensor, which is disposed above the receiving box 21 and is used to detect the distance between itself and the bottom surface of the receiving box 21. As the amount of material in the receiving box 21 increases, the distance value detected by the first distance sensor decreases. When the distance value reaches a first distance value, it is determined that the amount of material in the receiving box 21 has reached a first preset value, so that the cleaning mechanism 30 can be activated to clean the material in the receiving box 21 in a timely manner.

[0070] For example, the first distance sensor can be an infrared sensor, a laser sensor, a radar sensor, or a photoelectric sensor, as long as it can detect distance.

[0071] In some embodiments, the tobacco feeding device further includes a power distribution box 60, which is mounted on the frame 10. The power distribution box 60 is electrically connected to the first detection component and the cleaning mechanism 30. The first detection component sends the detected signal to the power distribution box 60. The power distribution box 60 determines whether the amount of material in the receiving box 21 has reached a first preset value based on the received signal. If it has, it controls the cleaning mechanism 30 to start.

[0072] Optionally, the distribution box 60 includes a main control board, which is electrically connected to the first detection component and the cleaning mechanism 30 respectively to control the cleaning.

[0073] In some embodiments, the tobacco feeding device further includes a second detection component for detecting the amount of material in the feeder 50. The second detection component is communicatively connected to the feeder 50. When the second detection component detects that the amount of material in the feeder 50 has reached a second preset value, the feeder 50 starts and discharges material to prevent the material in the feeder 50 from overflowing.

[0074] In some embodiments, the second detection component and the feeder 50 are electrically connected to the power distribution box 60, respectively. The detection component sends the detected signal to the power distribution box 60, and the power distribution box 60 determines whether the amount of material in the feeder 50 has reached a second preset value based on the received signal. If it has, the feeder 50 is controlled to start.

[0075] like Figure 4 As shown, the feeder 50 includes a feed hopper 51, a bin door 53, and an opening and closing drive assembly 54. The bottom end of the feed hopper 51 is provided with a feed port. The bin door 53 is movably disposed at the bottom end of the feed hopper 51 to open or close the feed port. The opening and closing drive assembly 54 is connected to the bin door 53 and is used to drive the bin door 53 to move relative to the feed hopper 51 to realize the opening and closing of the feed port.

[0076] In some embodiments, the hopper door 53 is rotatably connected to the feeding hopper 51, and the opening and closing drive assembly 54 includes a rotary motor, the output end of which is connected to the hopper door 53 to drive the hopper door 53 to open or close the feeding port.

[0077] In some embodiments, the feeding hopper 51 is provided with a window 511, and a window plate 52 is detachably or movably connected to the window 511 to open or close the window 511 so as to observe the situation inside the feeding hopper 51.

[0078] Optionally, the window panel 52 and the feeding hopper 51 are connected by screws for easy disassembly.

[0079] Alternatively, the window panel 52 may be made of a transparent material.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
