Description

Technical Field

[0001] The invention relates to the technical field of cigar processing, and in particular to a cigar fixed-length cutting device and a cutting method. Background Art

[0002] The cigar is made up of a binder wrapped around the cigar core to form a cigar embryo, and a wrapper wrapped around the cigar embryo to form a cigarette. Figure 1 As shown in the figure, after the cigar wrapper is wrapped around the embryo, there will be extra cigar wrapper at both ends of the cigarette. If the cigarette is not trimmed, the lighting end of the cigarette will be uneven and there will be no suction port at the suction end of the cigarette. Therefore, the fixed length cutting process can complete the fixed length and cutting of the cigarette. In traditional cigar processing, after the operator rolls the cigar, he manually places the cigarette on the cutting table and uses the cutting table to manually complete the fixed length cutting function. The characteristic is that the operator rolls a cigar and cuts it to the fixed length once, which wastes a lot of time.

[0003] A Chinese patent (publication number CN113729264A, publication date 20211203) discloses a cigar rolling machine, in which the inner bag of cigars cut by the inner bag cutting mechanism is transferred to the cigar rolling mechanism, and the shaping mechanism shapes and shapes the inner cigar blank, and then transfers it to the outer wrapping assembly through the outer bag conveying mechanism. At this time, the outer bag wrapper cut by the outer bag cutting mechanism is also transferred to the outer wrapping assembly, and the outer wrapping assembly wraps the outer bag wrapper on the inner cigar blank to form a cigar, and then the wrapped cigar is conveyed after the end shaping and length cutting by the discharge conveying mechanism, and the discharge conveyor of the front mechanism is used. When the cigar is clamped by the structure and reaches the slot position of the right scissor pair and the left scissor pair, the cutting motor drives the right scissor pair and the left scissor pair to cut the cigar to the specified length. It still adopts the solution of rolling a single cigar and then cutting it individually. In batch production, the upstream cigarette rolling speed is faster, while the cutting speed is slower. In order to match the cutting demand, the cigarette rolling speed needs to be reduced, resulting in low production efficiency of the entire production line. If the method of centralized cutting of the wrapper at the end of the cigarette is adopted, it is still necessary to manually feed the stacked cigarettes to the cutting component one by one, resulting in low feeding efficiency and difficulty in meeting the production efficiency requirements. Summary of the invention

[0004] The purpose of the present invention is to provide a cigar fixed-length cutting device and cutting method in view of the defects existing in the prior art, and to configure a supply device for temporarily storing cigarettes and a cutting device for cutting cigarettes to a fixed length. The supply device forms a storage bin for accommodating cigarettes through structures such as a frame, a side plate, a front baffle, a bracket, and a rear baffle, thereby providing a temporary storage space for cigarettes. One side of the side plate is rotatably connected to the front baffle, and the other side abuts the bracket, and the setting of the baffle and the rear baffle on the bracket ensures that the storage bin structure is stable and can effectively accommodate cigarettes; under the action of the cigarette pushing drive, the cigarette pushing block cooperates with the conveyor belt to cover the bottom opening of the storage bin, and pushes the cigarettes onto the conveyor belt to realize the orderly transportation of cigarettes. The supply device cooperates with the cutting device, and the cutting device receives and cuts the cigarettes transported by the supply device. Since the supply device can efficiently and stably transport cigarettes, the cutting device is no longer limited by the problems of slow upstream single-piece cutting speed and low manual feeding efficiency, thereby improving the production efficiency of the entire cigar fixed-length cutting device.

[0005] The first object of the present invention is to provide a cigar cutting-to-length device, which adopts the following scheme:

[0006] It includes a supply device and a cutting device, and the supply device includes:

[0007] frame;

[0009] A bracket is mounted on the frame, and is provided with a stopper abutting against the side plate and a rear stopper covering the opening on the other side of the storage bin;

[0010] The conveying assembly includes a cigarette pushing block and a rotating conveyor belt, one side of the conveyor belt extends below the bottom opening of the storage bin, and the other side extends outside the storage bin, one side of the conveyor belt and the cigarette pushing block jointly cover the bottom opening of the storage bin, the cigarette pushing block is connected to a cigarette pushing driving member, and a cigarette storage part for receiving and storing cigarettes is provided on the conveyor belt;

[0011] The cutting device receives and cuts the cigarettes delivered by the supply device.

[0012] Furthermore, the two side panels are respectively rotatably connected to the front baffle, and the stopper releases the other side of the side panel to allow the side panel to rotate relative to the front baffle, thereby opening or closing the accommodating compartment.

[0013] Furthermore, the stopper is a magnetic block, and a magnetic portion is provided at a position of the side plate corresponding to the contact position of the stopper, and the stopper uses magnetic force to absorb the magnetic portion to hold the side plate.

[0014] Furthermore, the front baffle and the rear baffle are respectively slidably mounted on the frame and are respectively equipped with locking members so as to be locked after the distance between the two side plates is adjusted and the two side plates correspond to the distance between the rear baffle.

[0015] Furthermore, the rear baffle is provided with an inclined section inclined toward a side close to the accommodating bin, the inclined section is spaced apart from the conveyor belt, and the smoke storage portion passes through a gap between the inclined section and the conveyor belt under the drive of the conveyor belt.

[0016] Furthermore, the conveyor belt is provided with a plurality of cigarette storage sections, which are distributed at intervals along the rotation direction of the conveyor belt.

[0017] Furthermore, it also includes a transfer device, which includes a transfer robot arm and a transfer clamp. The transfer clamp is installed at the end of the transfer robot arm. The transfer clamp clamps the cigarettes on the cigarette storage part and transports them to the cutting device.

[0018] Furthermore, it also includes an output device, on which is provided a conveyor belt for receiving the cut cigarettes output by the cutting device; the cutting device includes a cigarette pushing rod and a cutter, the cigarette pushing rod receives the cigarettes conveyed by the transfer clamp, and cutters are respectively provided on both sides of the cigarette pushing rod.

[0019] The second object of the present invention is to provide a cutting method of the cigar fixed-length cutting device as described in the first object, comprising:

[0020] A side plate is rotated to open, and the cut cigarettes are stacked in the storage bin. The side plate is rotated to close, and the cigarettes at the bottom of the storage bin are stacked on the cigarette pushing block and the conveyor belt.

[0021] The conveyor belt rotates to move the cigarette storage section along the conveyor belt. When the cigarette storage section rotates to the bottom of the storage bin, the cigarette pusher shakes to promote the loosening of the cigarettes. The cigarettes fall into the cigarette storage section and move with the cigarette storage section to the outside of the storage bin. After being clamped by the transfer device, they are fed to the cutting device. The transfer device resets and waits for the next cigarette to be clamped.

[0022] The cutting device cuts the cigarettes into fixed lengths and then outputs them.

[0023] Furthermore, the size of the accommodating bin can be changed by adjusting the relative position of the front baffle and the frame, and adjusting the relative position of the bracket and the frame, so as to accommodate cigarettes of different sizes.

[0024] Compared with the prior art, the present invention has the following advantages and positive effects:

[0025] Cigar rolling machines use a single-rod cutting method after rolling, which affects production efficiency. A supply device is configured to temporarily store cigarettes and a cutting device is configured to cut cigarettes to a fixed length. The supply device forms a storage bin for cigarettes through a frame, side panels, front baffles, brackets, rear baffles and other structures to provide temporary storage space for cigarettes. One side of the side panel is rotated to connect to the front baffle, and the other side abuts the bracket. The setting of the baffle and rear baffle on the bracket ensures that the storage bin structure is stable and can effectively accommodate cigarettes. Under the action of the cigarette push drive, the cigarette push block cooperates with the conveyor belt to cover the bottom opening of the storage bin and push the cigarettes onto the conveyor belt to achieve orderly transportation of cigarettes. The supply device cooperates with the cutting device, and the cutting device receives and cuts the cigarettes transported by the supply device. Since the supply device can efficiently and stably transport cigarettes, the cutting device is no longer limited by the problems of slow upstream single-rod cutting speed and low manual feeding efficiency, thereby improving the production efficiency of the entire cigar fixed-length cutting equipment.

[0026] The two side panels are rotatably connected to the front baffle, and the block can release the other side of the side panel so that the side panel can rotate relative to the front baffle, thereby opening or closing the storage compartment. This design facilitates the placement and removal of cigarettes. When it is necessary to stack cigarettes in the storage compartment, the side panel can be rotated to open, and then rotated to close after the operation is completed, which improves the convenience of stacking cigarettes. The block adopts a magnetic block, and a magnetic part is provided at the corresponding position of the side panel. The position of the side panel is maintained by magnetic adsorption. Compared with the traditional mechanical fixing method, the operation is simpler, and while ensuring the stable fixation of the side panel, it is easy to open and close the side panel quickly, thereby improving the use efficiency.

[0027] The front baffle and the rear baffle are slidably mounted on the frame and equipped with locking parts, so that after adjusting the distance between the two side panels and the distance between the two side panels and the rear baffle, they can be locked by the locking parts. Its advantage is that the size of the storage bin can be flexibly adjusted according to cigarettes of different sizes, which enhances the adaptability of the equipment to cigarettes of various specifications.

[0028] The conveyor belt is provided with a plurality of cigarette storage sections which are spaced apart along the rotating direction, so as to ensure that during the continuous operation of the conveyor belt, there are cigarette storage sections to continuously receive the cigarettes dropped from the storage bin, thereby realizing the continuous transportation of cigarettes and providing a stable material supply for the subsequent cutting process.

DETAILED DESCRIPTION

[0040] Example 1

[0041] In a typical embodiment of the present invention, Figure 1-Figure 9 As shown, a cigar fixed-length cutting device is provided.

[0042] There are two problems in the existing cigar fixed-length cutting technology. First, in the solution of cutting a single cigarette after rolling, the upstream cigarette rolling speed 8 is fast but the cutting speed is slow. In order to match the cutting, the rolling speed needs to be reduced, resulting in low production efficiency of the entire production line; second, in the method of centralized cutting of the end wrapper of the cigarette 8, the stacked cigarettes 8 are manually fed to the cutting component one by one, and the feeding efficiency is low, which makes it difficult to meet the production efficiency requirements. Based on this, this embodiment provides a cigar fixed-length cutting device, which is equipped with a supply device 1 for temporarily storing cigarettes 8 and a cutting device 3 for cutting the cigarettes 8 to a fixed length. A storage bin 11 for accommodating cigarettes 8 is formed in the supply device 1, which can stack cigarettes 8, and a conveyor belt 12 is used to take out the stacked cigarettes 8 from the bottom and transport them to the cutting device 3. The supply device 1 can efficiently and stably transport the cigarettes 8, so that the cutting device 3 is no longer limited by the problems of slow upstream single-piece cutting speed and low manual feeding efficiency, thereby improving the production efficiency of the entire cigar fixed-length cutting device.

[0043] like Figure 1-Figure 9 As shown, the cigar fixed-length cutting device includes a supply device 1, a cutting device 3, a transfer device 2 and an output device 4. The transfer device 2 transfers the cigarettes 8 output by the supply device 1 to the cutting device 3, and the cutting device 3 cuts the cigarettes 8 and then puts the cigarettes 8 into the output device 4 for unloading.

[0044] like Figure 2 As shown, the supply device 1 mainly includes a frame 5, a side plate 7, a bracket and a conveying assembly. The frame 5 serves as the supporting structure of the entire supply device 1, providing a mounting base for other components to ensure that the relative positions of the components remain stable during operation. Figure 1 As shown, the frame 5 is a frame structure, and the containing bin 11 and the conveying assembly are placed in the frame structure of the frame 5.

[0045] like Figure 3 As shown, two side panels 7 are provided, and the two side panels 7 are spaced apart from each other to form a receiving bin 11 for receiving cigarettes 8, which is used to store the cigarettes 8 to be cut. One side of each side panel 7 is rotatably connected to the front baffle 6, and the other side is abutted against the bracket. Through this connection mode, the relative position between the side panels 7 can be ensured, and the receiving bin 11 can be opened or closed by rotating the side panels 7 when needed, so as to facilitate the insertion and removal of cigarettes 8.

[0046] The front baffle 6 is installed on the frame 5, covering the opening on one side of the storage bin 11, preventing the cigarettes 8 from scattering from one side of the front baffle, and the front baffle 6 assists the side panel 7 to form the storage bin 11 for accommodating cigarettes 8, preventing the cigarettes 8 from falling from this side, and at the same time provides a rotation connection point for the side panel 7. The front baffle 6 is installed on the frame 5, maintaining its own position and providing a stable structural foundation for the installation of the side panel 7. The side panel 7 and the front baffle 6 can be connected by hinges, hinges, etc.

[0047] The bracket is mounted on the frame 5, and a stopper 9 and a rear stopper 10 are provided on the bracket. On the one hand, the stopper 9 on the bracket abuts against the side plate 7, assisting in maintaining the relative position of the side plate 7 and enhancing the structural stability of the storage bin 11; on the other hand, the rear stopper 10 is mounted on the bracket to cover the opening on the other side of the storage bin 11, further improving the sealing of the storage bin 11 and ensuring the stable storage of the cigarettes 8.

[0048] like Figure 4 As shown, the conveying assembly includes a conveyor belt 12 and a cigarette pushing block 15, and the cigarette pushing block 15 is connected to a cigarette pushing driving member 16, and together with one side of the conveyor belt 12, covers the bottom opening of the storage bin 11. During operation, the cigarette pushing block 15 can shake under the action of the cigarette pushing driving member 16, so as to promote the loosening of the cigarettes 8 at the bottom of the storage bin 11, so that the cigarettes 8 fall into the cigarette storage portion 14 on the conveyor belt 12, and play the role of pushing and assisting the cigarettes 8 to fall.

[0049] The conveyor belt 12 rotates, with one side extending to the bottom opening of the storage bin 11 to receive the cigarettes 8, and the other side extending to the outside of the storage bin 11 to transport the cigarettes 8 out of the storage bin 11. The cigarette storage part 14 on the conveyor belt 12 is used to receive and store the cigarettes 8 to ensure the stability of the cigarettes 8 during the conveying process.

[0050] The cutting device 3 can receive the cigarettes 8 delivered by the supply device 1 and cut them, completing the key operation of cutting the cigars to a fixed length.

[0051] like Figure 5 and Figure 4 As shown, through the design of the storage bin 11, cigarettes 8 can be stacked in batches, which greatly improves the loading efficiency compared to manually loading one by one to the cutting component. At the same time, the automated operation of the conveying component, such as the rotary conveying of the conveyor belt 12 and the auxiliary dropping of the cigarette pushing block 15, further ensures the continuity and efficiency of the supply of cigarettes 8, and solves the problem of low loading efficiency in the centralized cutting method.

[0052] The supply device 1 can efficiently and stably convey the cigarettes 8 to the cutting device 3, so that the cutting device 3 is no longer limited by the problem of slow single-piece cutting speed upstream. The cutting device 3 can perform cutting operations continuously, thereby improving the production efficiency of the entire cigar fixed-length cutting equipment, solving the problem of low production efficiency caused by the cutting link in the existing production line, and realizing efficient cigar fixed-length cutting production.

[0053] It is not convenient enough when stacking and taking out cigarettes 8, and the operation efficiency is low. In this regard, in this embodiment, the two side panels 7 are respectively rotatably connected to the front baffle 6, and the accommodating chamber 11 can be flexibly opened or closed to facilitate the batch placement and removal of cigarettes 8. The block 9 is a magnetic block, and the side panel 7 is provided with a magnetic suction part, which uses magnetic force to adsorb and maintain the position of the side panel 7. The operation is simple and the fixation is reliable. The efficiency of stacking and taking out cigarettes 8 is improved, and the time and difficulty of manual operation are reduced. At the same time, the magnetic fixation method is more convenient than the traditional mechanical fixation, which improves the convenience of equipment use.

[0054] In a cigar production line, different types of cigarettes 8 often have different lengths. Existing equipment is difficult to adapt to cigarettes 8 of different sizes and specifications, and has poor versatility. In this regard, in this embodiment, the front baffle 6 and the rear baffle 10 are respectively slidably mounted on the frame 5 and are equipped with locking members. The distance between the two side panels 7 and the distance between the two side panels 7 and the rear baffle 10 can be adjusted according to the size of the cigarettes 8. After the adjustment is completed, the locking is completed, so that the storage bin 11 can adapt to cigarettes 8 of different specifications.

[0055] like Figure 3 As shown, a slide groove for matching the locking piece is preset on the frame 5, and the locking piece is connected to the front baffle 6 or the rear baffle 10 after sliding into the slide groove. The locking piece connected to the front baffle 6 can adjust the positions of the two front baffles 6 corresponding to the two side panels 7, and can be locked after adjustment; the locking piece connected to the rear baffle 10 can adjust the positions of the two rear baffles 10, and can be locked after adjustment. It can be understood that when the locking piece connected to the rear baffle 10 adjusts the position of the rear baffle 10, it also drives the block 9 to move, so that the distribution position of the block 9 matches the position of the side panel 7 to adapt to different width adjustments. The locking piece can be a bolt, a screw, etc.

[0056] The front baffle 6 and the rear baffle 10 are respectively slidably mounted on the frame 5, thereby enhancing the adaptability of the equipment to cigarettes 8 of various specifications, improving the versatility of the equipment, and reducing the cost of replacing equipment for enterprises to produce cigars of different specifications.

[0057] When the cigarettes 8 fall from the storage bin 11 into the cigarette storage section 14 on the conveyor belt 12, problems such as jamming and blocking are likely to occur, which affects the conveying efficiency. In response to this, an inclined section 13 is provided on the rear baffle 10. The inclined section 13 is inclined toward the side close to the storage bin 11 and is arranged at intervals from the conveyor belt 12. The cigarette storage section 14 passes through the gap between the two under the drive of the conveyor belt 12. The inclined section 13 can guide the cigarettes 8 to fall smoothly into the cigarette storage section 14, avoiding poor conveying of the cigarettes 8. The conveying process of the cigarettes 8 from the storage bin 11 to the conveyor belt 12 is optimized, the stability and efficiency of the conveying of the cigarettes 8 are improved, and the continuity of the feeding device 1 to the cutting device 3 is ensured.

[0058] The conveyor belt 12 with a single cigarette storage section 14 cannot meet the demand for continuous and efficient transportation of cigarettes 8, affecting the overall production efficiency. In this regard, in this embodiment, multiple cigarette storage sections 14 are spaced apart along the rotation direction on the conveyor belt 12. When the conveyor belt 12 is running, there can be a continuous cigarette storage section 14 to receive the cigarettes 8 falling from the storage bin 11, so as to realize the continuous transportation of cigarettes 8. The conveyor belt 12 has a higher capacity for transporting cigarettes 8, providing a continuous and stable supply of cigarettes 8 to the cutting device 3, and further improving the production efficiency of the entire cutting device.

[0059] It should be pointed out that if Figure 5 As shown, the cigarette storage section 14 can be formed by setting baffles, baffles, etc. The cigarette storage section 14 can be a groove structure. When the cigarette pushing driving member 16 pushes the cigarette pushing block 15, the cigarette 8 moves slightly in the accommodating bin 11. At this time, the cigarette 8 enters the cigarette storage section 14 and is taken away. The cigarette storage section 14 of appropriate size is selected to ensure that each cigarette storage section 14 can only store one cigarette 8. Even if two cigarettes 8 are stacked and transported in the cigarette storage section 14, as the conveyor belt 12 rotates, the excess cigarettes 8 will still fall out of the cigarette storage section 14 under the resistance of other cigarettes 8 outside or the blocking effect of the inclined section 13, thereby meeting the demand for transporting a single cigarette 8.

[0060] like Figure 6 As shown, the transfer device 2 is composed of a transfer mechanical arm 18 and a transfer clamp 17. The transfer clamp 17 is installed at the end of the transfer mechanical arm 18, which can accurately clamp the cigarettes 8 on the cigarette storage part 14 and transport them to the cutting device 3. After the loading is completed, it resets and waits for the next operation. The automatic and accurate transfer of cigarettes 8 from the supply device 1 to the cutting device 3 is realized, the error that may be caused by manual transfer is reduced, the transfer efficiency and accuracy are improved, and the efficient cutting process is guaranteed.

[0061] Specific, combined Figure 6 and Figure 7 The transport robot arm 18 is composed of a base and a plurality of connecting rods to form a four-bar linkage. According to the rod length condition, the four-bar linkage is a double rocker mechanism, the base is used as the frame rod of the double rocker mechanism, the connecting rods of the double rocker mechanism are respectively connected to the base through the connecting rods, one of the connecting rods is connected to the driving motor, and the transport fixture 17 is connected to the hinge shaft between the connecting rod and the connecting rod, so that it follows the movement of the connecting rod during the transport process, and its movement trajectory meets the needs of transporting cigarettes 8.

[0062] The drive motor provides power for the planar four-bar linkage. By controlling the rotation direction and phase of the drive motor, the four-bar linkage can be controlled to move left and right. Figure 1 In the posture shown, the left extreme position of the four-bar linkage is the position for placing the cigarette 8 into the cutting device 3 , and the right extreme position is the position for picking up the cigarette 8 from the conveyor belt 12 of the supply device 1 .

[0063] The transfer fixture 17 includes two clamping plates, which are respectively fixed on the gear shafts by bolts, the two gear shafts are meshed with each other, and the gear shafts are connected to the driving motor. By controlling the rotation direction and phase of the driving motor, the opening and closing of the clamping plates can be controlled, and the opening angle of the clamping plates can be adjusted.

[0064] There is no effective way to output the cut cigarettes 8, and the cutting efficiency and precision of the cutting device 3 need to be improved. In this regard, the conveyor belt 23 of the output device 4 receives the cut cigarettes 8 output by the cutting device 3, so as to achieve the rapid output of the cigarettes 8. The cigarette pusher 22 of the cutting device 3 receives the cigarettes 8 transported by the transport fixture 17, and the cutters 21 on both sides can quickly cut the cigarettes 8 to a fixed length. The output efficiency of the cut cigarettes 8 is improved, and the design of the cigarette pusher 22 of the cutters 21 on both sides improves the cutting efficiency and cutting precision, ensuring the efficient operation of the cigar fixed-length cutting equipment.

[0065] Specifically, Figure 8 As shown, the cutting device 3 is composed of a cutter 21, a cutting arm 20, a driving motor, a cigarette push rod 22 and other parts. The cutting principle is the same as that of scissors, which belongs to shearing. The driving motor is a stepping motor, which controls the corresponding driving shaft 19 respectively. The driving shaft 19 is installed on a rotating support, and the cutting arm 20 is installed on the driving shaft 19 through a clamp. Two cutting arms 20 are installed on each driving shaft 19 at intervals, and a cutter 21 is installed at the end of the cutting arm 20. The two cutting arms 20 fixed by different driving shafts 19 are a group, and a pair of shearing mechanisms are formed therebetween. The two stepping motors rotate in opposite directions and have the same phase. For example, when one of the stepping motors rotates clockwise, the other stepping motor rotates counterclockwise, and the four cutting arms 20 move from both ends to the middle cigarette 8 to realize the cutting function.

[0066] like Figure 8 As shown, the clamp corresponding to the cutting arm 20 is fixed by an adjusting bolt, and the positions of the two groups of cutting arms 20 can be adjusted respectively by adjusting the bolt. By adjusting the position of the cutting arm 20, the distance between the two groups of cutters 21 is ensured to be the length of the cigar after fixed length cutting. By setting the adjustment margin, it is ensured that the cutting device 3 can cut cigars of different diameters and different circumferences, and it is a flexible cutting device 3.

[0067] The push rod 22 is connected to one of the drive shafts 19. As the two sets of cutting arms 20 move toward each other (cutting action), after the cutting action is completed, the push rod 22 also rotates with the drive shaft 19, and the cigar on the push rod 22 is sent out and enters the conveyor belt 23. This movement realizes the delivery of the last cut cigar to the conveyor belt 23 of the output device 4.

[0068] The output device 4 is composed of a conveyor belt 23, a transmission roller, a motor, a bracket and other parts. The bracket is installed on the equipment base by bolts, and the drive motor and the drive roller are installed on the bracket. The cigarette push rod 22 sends the cigarette 8 to the conveyor belt 23. The drive motor rotates clockwise, driving the drive roller to rotate clockwise, and the drive roller drives the conveyor belt 23 to rotate clockwise. When the conveyor belt 23 collects a certain number of cigars, the operator takes out the cigars.

[0069] Example 2

[0070] In another typical embodiment of the present invention, Figure 1-Figure 9 As shown, a cutting method of a cigar fixed-length cutting device is provided, using the cigar fixed-length cutting device as in Example 1.

[0071] A cutting method of a cigar fixed-length cutting device, comprising:

[0072] A side plate 7 is rotated to open, and the cut cigarettes 8 are stacked in the storage bin 11. The side plate 7 is rotated to close, and the cigarettes 8 at the bottom of the storage bin 11 are stacked on the cigarette pushing block 15 and the conveyor belt 12.

[0073] The conveyor belt 12 rotates to move the cigarette storage section 14 along the conveyor belt 12. When the cigarette storage section 14 rotates to the bottom of the storage bin 11, the cigarette pusher 15 shakes to promote the loosening of the cigarette 8. The cigarette 8 falls into the cigarette storage section 14 and moves with the cigarette storage section 14 to the outside of the storage bin 11. The cigarette 8 is clamped by the transfer device 2 and then fed to the cutting device 3. The transfer device 2 is reset to wait for the next cigarette 8 to be clamped.

[0074] The cutting device 3 cuts the cigarettes 8 into fixed lengths and outputs them.

[0075] Through the coordinated work of the conveyor belt 12, the cigarette pushing block 15 and the transfer device 2, efficient and automatic transportation of the cigarettes 8 from the storage bin 11 to the cutting device 3 is achieved, solving the problem of low efficiency of manual loading in the prior art.

[0076] By adjusting the relative positions of the front baffle 6 and the frame 5, and adjusting the relative positions of the bracket and the frame 5, the size of the storage bin 11 can be changed to accommodate cigarettes 8 of different sizes. This ensures the efficient cutting process, and also reflects the versatility and flexibility of the equipment, which can meet different production needs.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
