Abstract
Description
Technical Field
[0001] This application relates to the field of feeding technology, and in particular to a feeding device and tobacco production equipment. Background Technology
[0002] Cigarette processing is a crucial step in cigarette production. In this process, tobacco leaves are finely cut into thin shreds, which are then processed through drying, puffing, and flavoring to achieve specific moisture content, density, color, and aroma to meet the demands of subsequent cigarette manufacturing. Feeding is a key step in cigarette processing; using a quantitative feeding device allows for precise control and uniform mixing of the raw tobacco leaves, thereby improving the process parameters and control accuracy, and contributing to achieving the goal of refined processing.
[0003] However, in the relevant technologies, the feeding device does not have a good emergency means. Once the motor in the feeding device fails and needs to be repaired, the tobacco shreds will accumulate inside the feeding device, making it difficult to feed. This not only affects the transportation of tobacco shreds, but also affects the production quality of tobacco shreds if the accumulation time is too long. Utility Model Content
[0004] Therefore, it is necessary to provide a feeding device and tobacco production equipment to address the problem of the lack of effective emergency measures for feeding devices.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

The storage cavity is used to store materials, and the discharge port is located below the storage cavity along the direction of gravity and communicates with the unloading bin.
[0011] In one embodiment of the first aspect, the feeding device further includes a support assembly for supporting the storage bin;
[0012] The support assembly includes two supports arranged opposite each other, the unloading box and the feeding box are both arranged between the two supports, and the two ends of the uniform roller are rotatably connected to the two supports respectively.
[0013] In one embodiment of the first aspect, the support includes a column and a base, the base being fixed below the column in the direction of gravity.
[0014] In one embodiment of the first aspect, the support assembly further includes a mounting base, the two ends of which are respectively connected to the two brackets, and the storage box is mounted on the mounting base.
[0015] In one embodiment of the first aspect, the mounting base has a mounting groove in the middle, and one end of the storage box with a discharge port passes through the mounting groove.

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.
[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.
[0032] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist.

Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] 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.
[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on 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.
[0036] See Figure 1 As shown, an embodiment of this application provides a feeding device 100, which can be used for tobacco feeding operations in the cigarette production process and can meet the emergency feeding needs in case of device failure, so as to avoid material blockage and thus affect product quality.
[0037] It should be noted that the feeding device 100 provided in this application is not limited to tobacco feeding scenarios, but can also be applied to other material supply scenarios. For ease of understanding, the embodiments of this application only use the tobacco feeding scenario as an example.
[0038] Specifically, the feeding device 100 includes a feeding assembly 110, a discharging assembly 120, and a handle 130. The feeding assembly 110 disperses and guides the tobacco shreds downwards to the discharging assembly 120, which is located downstream of the feeding assembly 110 and discharges the material from the feeding assembly 110 to the corresponding production line conveyor belt. The discharging assembly 120 operates synchronously with the feeding assembly 110 to ensure steady material transport, uniform feeding, and prevent outlet blockage. The handle 130 is connected to both the discharging assembly 120 and the feeding assembly 110 to provide a manual emergency discharge method in case of a malfunction in the feeding assembly 110, preventing prolonged material accumulation due to maintenance and ensuring the quality of tobacco production.
[0039] Continue reading Figure 2As shown, in some embodiments, the feeding assembly 110 includes a feeding box 111 and a dispensing component 112. The feeding box 111 is provided with a feeding port, and the dispensing component 112 is at least partially disposed within the feeding box 111 and configured to be able to rotate in a controlled manner.
[0040] Specifically, the top of the feeding box 111 is open to facilitate the entry of materials, and the bottom of the feeding box 111 is provided with a feeding port to convey the materials to the discharge assembly 120. The material separating component 112 is provided inside the feeding box 111 to disperse and guide the tobacco shreds during feeding, thereby preventing the tobacco shreds from accumulating and causing blockage of the feeding port, and improving the feeding rate.
[0041] Furthermore, the material distribution component 112 includes a rotating shaft 1121 and multiple material distribution plates 1122. The rotating shaft 1121 rotates through the unloading box 111, and each material distribution plate 1122 is equidistantly distributed on the periphery of the rotating shaft 1121 and located inside the unloading box 111.
[0042] For example, the number of distributing plates 1122 can be two, three, four, five, six, etc., and can be reasonably set according to the size of the feeding box 111 and the tobacco conveying rate, and is not specifically limited here. In this specific embodiment, there are four distributing plates 1122. The four distributing plates 1122 are fixed at equal intervals around the circumference of the rotating shaft 1121, so that under the drive of external force, the rotating shaft 1121 drives each distributing plate 1122 to rotate. During the rotation, the distributing plates 1122 break up the accumulated tobacco and guide it to the discharge assembly 120 in batches.
[0043] Furthermore, the feeding assembly 110 also includes a motor 113, which is connected to one end of the rotating shaft 1121.
[0044] Specifically, the motor 113 can be a servo motor 113, which can precisely control the position, speed and torque to achieve high-precision motion control. Driven by the motor 113, the rotating shaft 1121 drives the material distribution plate 1122 to rotate, and can reasonably adjust the corresponding speed according to the amount of tobacco accumulated.
[0045] Continue reading Figure 3 As shown, in some embodiments, the discharge assembly 120 includes a feeding box 121 and a uniform roller 122. The feeding box 121 is connected to the discharge port and has a feeding port. The feeding port is located on the side of the feeding box 121 away from the discharge box 111. The uniform roller 122 is rotatably mounted inside the feeding box 121 and is drivenly connected to the material distribution component 112. A handle 130 is connected to one end of the uniform roller 122 and can controllably drive the uniform roller 122 to rotate.
[0046] Specifically, the upper part of the feeding box 121 is also open and located below the unloading box 111 to communicate with the unloading port and receive the tobacco from the unloading box 111. The equalizing roller 122 is located inside the feeding box 121 and is drivenly connected to the rotating shaft 1121 so that when the motor 113 drives the rotating shaft 1121 to rotate, the equalizing roller 122 rotates synchronously to disperse the tobacco entering the feeding box 121 and evenly guide the falling material through the feeding port onto the conveyor belt below, preventing the tobacco from piling up on the conveyor belt.
[0047] When the motor 113 fails and the rotating shaft 1121 cannot rotate automatically, the material accumulates in the feeding box 111. At this time, the handle 130 can be turned manually to make the uniform roller 122 rotate, which in turn drives the rotating shaft 1121 and the distributing plate 1122 to rotate, so as to realize the emergency discharge of the material and avoid the problem of product quality deterioration due to the accumulation of tobacco shreds for too long.
[0048] Furthermore, the discharge assembly 120 also includes a transmission rod 123, one end of which is connected to the uniform roller 122, the other end of which is connected to the handle 130, and is connected to the rotating shaft 1121 in a transmission connection.
[0049] Specifically, the transmission rod 123 enables the uniform roller 122 and the material distribution component 112 to rotate synchronously when the material distribution component 112 rotates. In case of emergency discharge due to motor 113 failure, the transmission rod 123 can be rotated by the handle 130 to rotate the material distribution component 112 and discharge the accumulated tobacco.
[0050] Furthermore, the feeding assembly 110 also includes a first pulley 114 and a drive belt 115, with the first pulley 114 mounted on the rotating shaft 1121. The discharging assembly 120 also includes a second pulley 124, which is mounted on the transmission rod 123, and the drive belt 115 is wound around the first pulley 114 and the second pulley 124 in sequence.
[0051] Specifically, the transmission belt 115 passes around the first pulley 114 and the second pulley 124 in sequence, so that when either the rotating shaft 1121 or the transmission rod 123 rotates, the transmission belt 115 can achieve synchronous operation and maintain stable feeding and conveying.
[0052] In some embodiments, the feeding device 100 further includes a storage box 140, which has a storage cavity 141 and a discharge port. The storage cavity 141 stores materials, and the discharge port is opened below the storage cavity 141 along the direction of gravity and communicates with the unloading box 111.
[0053] Specifically, the storage bin 140 stores a large amount of tobacco shreds through the storage chamber 141, and the tobacco shreds fall into the feeding bin 111 through the discharge port. The feeding bin 111 is located below the storage bin 140, and the tobacco shreds are transferred to the feeding bin 121 through the material distribution component 112.
[0054] Continue reading Figure 4 As shown, in some embodiments, the feeding device 100 further includes a support assembly 150 for supporting the storage bin 140. The support assembly 150 includes two supports 151 arranged opposite to each other, with the discharge bin 111 and the feeding bin 121 both disposed between the two supports 151, and the two ends of the uniform roller 122 rotatably connected to the two supports 151 respectively.
[0055] Specifically, the support assembly 150 is used to fix the entire device to the ground or work platform to achieve the installation and fixation of each component. The storage bin 140 is located above the bracket 151, and the feeding bin 111 and the feed bin 121 are installed sequentially from top to bottom. One bracket 151 has holes for mounting the motor 113 to ensure the stable installation of the feeding assembly 110. At the same time, the two ends of the uniform roller 122 are respectively inserted through the two brackets 151 so that it can rotate relative to the two brackets 151 and follow the rotation under the drive of the feeding assembly 110.
[0056] Preferably, for ease of operation, the handle 130 is installed on the end of the uniform roller 122 near the motor 113.
[0057] In some embodiments, the bracket 151 includes a column 1511 and a base 1512, with the base 1512 fixed below the column 1511 along the direction of gravity.
[0058] Specifically, both the column 1511 and the base 1512 are square rods, with the column 1511 vertically fixed to the center of the base 1512, forming a T-shaped structure. In this way, the horizontally positioned base 1512 contacts the ground, increasing the contact area and ensuring the overall stability of the device.
[0059] In some embodiments, the support assembly 150 further includes a mounting base 152, with its two ends connected to two brackets 151 respectively, and the storage box 140 mounted on the mounting base 152.
[0060] Specifically, the mounting base 152 is positioned above the bracket 151, and then the storage box 140 is installed on the mounting base to facilitate the stable installation of the storage box 140.
[0061] In some embodiments, the mounting base 152 has a mounting groove 1521 in the middle, and the end of the storage box 140 with a discharge port passes through the mounting groove 1521.
[0062] Specifically, the mounting base 152 has bosses at both ends to form recessed mounting grooves 1521, and the mounting grooves 1521 penetrate through the bottom of the mounting base 152. The storage box 140 has a tapered opening structure at the bottom. The upper end of the mounting groove 1521 is larger than the lower through hole size, so that the lower end of the storage box 140 passes through the lower through hole of the mounting groove 1521. The upper part of the storage box 140 is restricted and fixed by the side of the mounting base 152 due to its larger size, so that the storage box 140 is suspended and fixed on the mounting base 152.
[0063] Embodiments of this application also provide a tobacco shred production apparatus, including the feeding device 100 in any of the above embodiments.
[0064] This embodiment has the feeding device 100 of any of the above embodiments, and therefore has all the beneficial effects of the feeding device 100 of any of the above embodiments, which will not be described in detail here.
[0065] The technical features of the above embodiments can be combined in any way. 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.
[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
