Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette packaging equipment, in particular to a cigarette supply mechanism. BACKGROUND

[0002] The cigarette supply mechanism is a key functional module of the cigarette packaging equipment, mainly used for realizing automatic transmission, accurate positioning and orderly arrangement of cigarettes from the storage bin to the packaging station. Its performance directly affects the production efficiency, product qualification rate and equipment operation stability of cigarette packaging, and is one of the core technologies for realizing high-speed and intelligent production of the tobacco industry.

[0003] In related technologies, the cigarette supply mechanism generally adopts negative pressure adsorption technology as the basic transmission scheme, and the typical structure includes a vacuum pump, a distribution valve group, an adsorption chamber and a pressure sensor. In the primary adsorption process, the vacuum pump outputs-60kPa negative pressure, and the air flow is distributed to 12 groups of adsorption chambers through the distribution valve, covering the filter end and the burning end of the cigarette. In the dynamic compensation process, when the transmission speed of the cigarette reaches 7000 cigarettes per minute, the pressure sensor monitors the pressure fluctuation of the adsorption chamber in real time, and triggers the compensation algorithm to maintain the stability of the negative pressure. In the staged release process, the electromagnetic valve is used to close the negative pressure in stages, so that the cigarette is separated from the adsorption force when entering the packaging station, and the inertial slip is avoided.

[0004] For the above-mentioned related technologies, the circular adsorption chamber has uneven adsorption force distribution for cigarettes with asymmetric cross sections such as cigarettes with edges, oval-shaped blasting beads and the like, resulting in a cigarette deviation of ±1.2mm during transmission, which causes packaging misalignment. INVENTION CONTENTS

[0005] In order to improve the problem of uneven adsorption force distribution of the adsorption chamber for asymmetric cigarettes by negative pressure adsorption, and prevent the phenomenon of packaging misalignment caused by cigarette deviation, the present application provides a cigarette supply mechanism.

[0006] The cigarette supply mechanism provided by the present application adopts the following technical scheme:

[0007] A cigarette supply mechanism, comprising a cigarette stock bin for containing a plurality of cigarettes, a cigarette group conveying belt arranged in a cigarette packaging equipment and located below the cigarette stock bin, a receiving plate assembly for receiving the cigarettes falling from the cigarette stock bin, and a pushing assembly for pushing the receiving plate assembly to approach / away from the cigarette group conveying belt, the cigarette stock bin is arranged at an upper position between the cigarette group conveying belt and the receiving plate assembly;

[0008] The cigarette material preparation warehouse comprises a cigarette warehouse back plate installed on a cigarette packaging device, a cigarette warehouse side plate arranged on both sides of the cigarette warehouse back plate, and a plurality of cigarette drop hoppers arranged at one side of the cigarette warehouse back plate.

[0009] By adopting the above technical solutions, the cigarette material preparation warehouse, the receiving plate assembly, the pushing assembly, and the cigarette group conveying belt are cooperatively arranged, so that the orderly transmission of the cigarettes from the material preparation warehouse to the packaging station is realized. The cigarettes are first dropped to the receiving plate assembly from the material preparation warehouse, and then are pushed close to the cigarette group conveying belt by the pushing assembly. This step-by-step transmission mode makes the cigarette transmission process more stable and controllable, and helps to improve the accuracy and efficiency of the cigarette transmission. In view of the problem that the existing circular adsorption chamber has uneven adsorption force distribution on the cross-section of the asymmetric cigarette, the technical solutions provided in the present application do not rely on the traditional circular adsorption chamber negative pressure adsorption mode, and the cigarette transmission structure is improved, the offset problem caused by uneven adsorption force on the asymmetric cigarette is reduced, the offset of the cigarette in the transmission process is effectively prevented, and the packaging misalignment phenomenon caused by the offset of the cigarette is avoided, the adaptability to the cross-section asymmetric cigarette such as the cigarette with an angle and the oval-shaped blasting bead cigarette is improved, and the application range of the cigarette supply mechanism is expanded.

[0010] Further, each of the cigarette drop hoppers is arranged along the height direction of the cigarette warehouse back plate, the height of each of the cigarette drop hoppers is sequentially increased, and the top side of each of the cigarette drop hoppers is at the same horizontal plane.

[0011] By adopting the above technical solutions, each of the cigarette drop hoppers is arranged along the height direction of the cigarette warehouse back plate and has a height sequentially increased, and the top side of each of the cigarette drop hoppers is at the same horizontal plane, so that the cigarettes dropped from the drop hoppers at different heights can be sequentially arranged in a specific order. The subsequent cigarettes need to form a cigarette group arranged in multiple layers for packaging, and the height difference ensures that the cigarettes can be stacked in an orderly manner, and each layer of cigarettes can be accurately dropped to the predetermined position, thereby improving the accuracy of the cigarette group formation.

[0012] Further, the cigarette drop hoppers are internally arranged with a plurality of partition plates, the thickness of each of the partition plates gradually decreases from top to bottom, and the minimum gap between each of the partition plates is matched with the diameter of the cigarette.

[0013] By adopting the technical scheme, multiple partition plates are arranged in the cigarette drop hopper at intervals, the thickness of the partition plates gradually decreases from top to bottom, the minimum gap between the partition plates matches the diameter of the cigarette, and the cigarettes are accurately screened. During the falling process of the cigarettes, the irregularly shaped cigarettes are blocked by the partition plates at the larger gap above, and the cigarettes with the standard diameter can smoothly pass through the gradually narrowing gap and slide downward. The specifications of the cigarettes finally entering the cigarette group are consistent, the quality of the cigarette group is improved, the number and rhythm of the falling cigarettes are accurately controlled, the situation of multiple cigarettes piling up and falling or blocking is avoided, and the stability of the cigarette supply is ensured.

[0014] Further, the back plate of the cigarette warehouse is provided with a first guide block between the two side plates, and the first guide block is provided with a first guide slope on both sides for the falling of the cigarettes.

[0015] By adopting the technical scheme, the first guide block is arranged between the two side plates of the back plate of the cigarette warehouse, and the first guide slope is arranged on both sides of the first guide block to provide a clear and accurate guide path for the falling of the cigarettes. When the cigarettes fall from the cigarette drop hopper, the cigarettes smoothly slide along the first guide slope, avoiding the situation of random deviation or jamming during the falling process of the cigarettes, ensuring that the cigarettes stably and orderly move downward, and improving the accuracy of the falling of the cigarettes. The first guide slope optimizes the falling track of the cigarettes, and by reasonably setting the angle and position of the guide slope, the cigarettes can obtain a suitable speed and direction during the falling process, so as to better enter the subsequent link.

[0016] Further, the back plate of the cigarette warehouse is provided with a second guide block between the two side plates, the second guide block is located at the middle position of the upper side of the two cigarette drop hoppers, the horizontal height of the second guide block is below the first guide block, and the second guide block is provided with a second guide slope on both sides for the falling of the cigarettes.

[0017] By adopting the technical scheme, the second guide block is arranged at the middle position of the upper side of the two cigarette drop hoppers and below the first guide block, and the second guide slope on both sides of the second guide block provides secondary accurate guidance for the falling of the cigarettes. When the cigarettes fall from the drop hoppers, the cigarettes are first guided by the first guide block and then adjusted by the second guide block, further ensuring that the cigarettes slide downward with more accurate position and posture, reducing the accumulated deviation that may occur during the long-distance falling of the cigarettes, enabling the cigarettes to more accurately reach the receiving plate assembly or the cigarette group conveying belt, improving the overall accuracy of the falling of the cigarettes, and further improving the reliability of the cigarette supply process.

[0018] Further, the receiving plate assembly comprises a plurality of supporting plates corresponding to each of the cigarette drop hoppers and a pushing seat for mounting each of the supporting plates, each of the supporting plates is arranged in a stepped manner on the upper side of the pushing seat to match the opening position of each of the cigarette drop hoppers, each of the supporting plates is vertically oriented to the cigarette group conveying belt, and the pushing seat is mounted on the pushing assembly.

[0019] By adopting the above technical solution, the plurality of supporting plates in the receiving plate assembly are correspondingly arranged with each of the cigarette drop hoppers, and are arranged in a stepped manner to match the opening position of the drop hoppers, which can accurately receive the cigarettes falling from the drop hoppers at different heights. When the supporting plate is pushed to the lower side of the opening of the cigarette drop hopper by the pushing seat and the pushing assembly, each supporting plate can accurately correspond to the corresponding drop hopper, and the cigarette can directly and stably fall into the supporting plate, reducing the risk of deviation and falling of the cigarette during the receiving process, ensuring the position accuracy of the cigarette in the receiving link, providing a basis for the subsequent transfer of the cigarette to the cigarette group conveying belt, and improving the reliability of the receiving link in the cigarette supply process. The supporting plate is vertically oriented to the cigarette group conveying belt, which is adapted to the direction of the falling cigarette and the subsequent direction of the transfer to the conveying belt, and conforms to the motion trajectory of the cigarette, so that the cigarette does not need to be adjusted in a large range during the process of falling into the supporting plate from the drop hopper and being pushed by the pushing assembly to the cigarette group conveying belt, reducing the energy loss and position deviation of the cigarette during the transmission process. The stepped arrangement of the supporting plate corresponds to the increasing height of the drop hoppers, and cooperates with the rhythm of the falling cigarette to optimize the entire cigarette transmission process and improve the transmission efficiency.

[0020] Further, a plurality of cigarette group receiving hoppers are arranged at equal intervals on the cigarette group conveying belt, and the width of the cigarette group receiving hopper matches the width of the supporting plate.

[0021] By adopting the above technical solution, the plurality of cigarette group receiving hoppers arranged at equal intervals on the cigarette group conveying belt have a width matching the width of the supporting plate, which provides accurate docking conditions for the transfer of the cigarette from the supporting plate to the cigarette group conveying belt. When the pushing assembly pushes the supporting plate carrying the cigarette to the cigarette group conveying belt, the cigarette can be accurately pushed into the corresponding cigarette group receiving hopper, reducing the deviation and falling of the cigarette during the transfer process, ensuring that each cigarette can accurately reach the predetermined position, and improving the reliability and accuracy of the transfer of the cigarette into groups.

[0022] Further, two limit blocks for controlling the number of cigarettes in each row of the cigarette group are symmetrically arranged on the inner wall of the cigarette group receiving hopper.

[0023] By adopting the above technical solution, the limit blocks symmetrically arranged on the two sides of the inner wall of the cigarette group receiving hopper can accurately control the number of cigarettes in each row, ensure the constant number of cigarettes in each row, and control the uniformity of the specifications of the cigarette group.

[0024] Further, the pushing assembly comprises a mounting base mounted on the cigarette packaging equipment and a pushing rod arranged on the mounting base, and the pushing seat is fixedly connected to the pushing rod away from one side of the cigarette group conveying belt.

[0025] By adopting the above technical scheme, the mounting base is fixed on the cigarette packaging equipment to provide a support base for the pushing assembly, the pushing rod is connected to the mounting base, and the pushing seat is fixed to the pushing rod away from one side of the cigarette group conveying belt, so that stable and continuous pushing force can be obtained for the pushing seat and the supporting plate for carrying the cigarettes during the pushing process, and the pushing rod is prevented from shaking or deviating due to equipment vibration or external force interference during the pushing process, thereby ensuring that the cigarettes can be accurately and stably pushed from the supporting plate assembly to the cigarette group conveying belt, and the reliability of the cigarette conveying link is improved.

[0026] In summary, the present application has at least one of the following beneficial technical effects:

[0027] 1. The cigarettes sequentially fall from the material preparation library through multiple levels of guidance, the first level of guidance block and the second level of guidance block provide precise guidance for the falling of the cigarettes, and ensure that the cigarettes slide down in a suitable posture. The supporting plates of the supporting plate assembly correspond one-to-one with the cigarette drop hoppers and are arranged in a stepped manner, which can accurately receive the cigarettes and reduce deviation and falling during receiving. The thickness of the partition plates in the cigarette drop hoppers gradually decreases from top to bottom, the minimum gap between the partition plates matches the diameter of the cigarettes, the cigarettes are accurately screened, only the cigarettes meeting the standards can smoothly slide down, the specifications of the cigarettes entering the cigarette group are consistent, and the quality of the cigarette group is improved.

The cigarette stocker 1 comprises a stocker back plate 11, a stocker side plate 12 and a plurality of cigarette drop hoppers 13. The stocker back plate 11 is fixedly connected to the side wall of the cigarette packaging device, and the stocker side plate 12 is symmetrically arranged and is fixedly connected to the two sides of the stocker back plate 11 perpendicularly. In actual use, the stocker 1 is provided with a front side baffle (not shown in the drawings) on the front side of the stocker side plate 12 to prevent the cigarettes from falling.

[0039] The number of cigarette drop hoppers 13 in this embodiment is three, so that the cigarette group forms a three-row structure arranged vertically. Each cigarette drop hopper 13 is arranged along the height direction of the back plate 11 of the cigarette warehouse, and the opening of the cigarette drop hopper 13 is arranged downward. Each cigarette drop hopper 13 is arranged at intervals on the side wall of the back plate 11 of the cigarette warehouse and below the two side plates 12 of the cigarette warehouse. The height of each cigarette drop hopper 13 increases in turn, and the top side of each cigarette drop hopper 13 is at the same horizontal plane. The discharge direction of the cigarette drop hopper 13 is perpendicular to the conveying direction of the cigarette group conveying belt 2.

[0040] Each cigarette drop hopper 13 is arranged with multiple partition plates 14 at intervals inside. The thickness of each partition plate 14 gradually decreases from top to bottom, and the minimum gap between each partition plate 14 matches the diameter of the cigarette. In the two side cigarette drop hoppers 13, the number of partition plates 14 is 6, so as to form 7 gaps for the falling of cigarettes together with the cigarette drop hopper 13. In the middle cigarette drop hopper 13, the number of partition plates 14 is 5, so as to form 6 gaps for the falling of cigarettes together with the cigarette drop hopper 13. The three cigarette drop hoppers 13 cooperate together, so that in the subsequent cigarette group, the three rows of cigarettes maintain a 7-6-7 arrangement.

[0041] The back plate 11 of the cigarette warehouse is arranged and fixedly connected with one first guide block 15 and two second guide blocks 16 between the two side plates 12 of the cigarette warehouse. The second guide blocks 16 are respectively located at each gap position on the upper side of the three cigarette drop hoppers 13, and the horizontal height of the second guide blocks 16 is below the first guide block 15. The first guide block 15 is provided with a first guide inclined surface 151 on both sides for the falling of cigarettes, and the second guide block 16 is provided with a second guide inclined surface 161 on both sides for the falling of cigarettes.

[0042] Referring to Figure 3 , the receiving plate assembly 3 includes a pushing seat 31 and multiple supporting plates 32. The number of supporting plates 32 is three and corresponds to each cigarette drop hopper 13. The pushing seat 31 is arranged at intervals on the upper side and integrally connected with a stepped block 311 for mounting each supporting plate 32. Each supporting plate 32 is arranged one by one and fixedly connected to each stepped block 311. The three supporting plates 32 are arranged in a stepped manner and vertically face the cigarette group conveying belt 2, so as to match the opening position of each cigarette drop hopper 13. The side of the pushing seat 31 away from the cigarette group conveying belt 2 is fixedly connected to the pushing rod 42.

[0043] Referring to Figure 3 and Figure 4A plurality of cigarette groups receiving hoppers 21 are arranged at equal intervals on the cigarette group conveying belt 2, and the width of the cigarette group receiving hopper 21 matches the width of each supporting plate 32. The inner wall of the cigarette group receiving hopper 21 is symmetrically arranged and integrally connected with two limit piece 22 for controlling the number of cigarettes in each row of the cigarette group.
