Description

Technical Field

[0001] The present invention relates to the technical field of cigar processing, and in particular to a mechanical device and method for quantitatively pushing cigarettes into a small cigar box. Background Art

[0002] Cigars are a special tobacco product consisting of three parts: filler, binder, and wrapper. Depending on the materials used to make these three parts, they are categorized as full-leaf rolled cigars, half-leaf rolled cigars, and cigar-shaped cigarettes. Depending on the processing method, they are further divided into handmade cigars and machine-made cigars. Traditionally, cigars are full-leaf rolled handmade cigars, meaning the filler, binder, and wrapper are all made of tobacco leaves, and the entire production process is done entirely by hand.

[0003] After cigars are made, they need to be packaged, and the first step in this process is boxing. In existing cigar box packaging processes, cigarettes are manually loaded into boxes. This is inefficient, typically producing 8 to 12 boxes per minute. The manual removal and loading process can easily lead to cigarette breakage, missing cigarettes, and quality defects. Summary of the Invention

[0004] In response to the shortcomings of the prior art, the present invention aims to provide a mechanical cigar box quantitative pusher and device and method. By integrating multiple devices, including a cigarette conveyor, a cigarette group counting device, and a cigarette group pusher, the device reduces cigarette breakage, eliminates missing cigarettes and quality defects, improves box packing efficiency, and overcomes the problems of the prior art. To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] In a first aspect, the present invention provides a mechanical cigar box quantitative push device, comprising:

[0006] A cigarette conveying device is provided with a transmission belt for conveying cigarettes;

[0007] a cigarette group counting device for receiving cigarettes conveyed by the cigarette conveyor, comprising a block structure and a counter; a waiting area is provided between the block structure and the conveying end of the cigarette conveyor, the waiting area being wide enough to accommodate a set number of cigarette groups; the counter is used to count cigarettes entering the waiting area and control the suspension of subsequent cigarettes from entering once the set number is reached;

[0008] The cigarette group pushing device is provided with a cigarette group pushing handle, which can push out a fixed amount of cigarette groups in the waiting area from its length direction.

[0009] As a further implementation, the cigarette conveying device further includes cigarette blocking blocks provided on both sides of the conveyor belt and a cigarette pressing block provided above the conveyor belt, and the distance between the two cigarette blocking blocks is adjustable.

[0010] As a further implementation method, the cigarette pressing block is supported by at least two pressing mechanisms, and the pressing mechanism includes a swingable bracket, one end of which is connected to the cigarette pressing block, and the other end is connected to a spring and under the action of the elastic force, the end connected to the cigarette pressing block has downward pressure.

[0011] As a further implementation, the block structure includes a block and a cylinder, and the cylinder can drive the block to move to adjust the width of the waiting area.

[0012] As a further implementation method, the cigarette group counting device also includes a pressure plate structure, which includes a pressure plate and a bracket supporting the pressure plate. The pressure plate is arranged above the waiting area, and the bracket is provided with two screws connected to the pressure plate. The pressure plate is kept in a horizontal state by adjusting the two screws.

[0013] As a further implementation, the cigarette group counting device further comprises the pressing block structure, which comprises a pressing block and a cylinder for driving the pressing block to rise and fall, and the pressing block is located above the conveying end of the conveyor belt.

[0014] As a further implementation method, the cigarette group pushing device also includes a bracket supporting the cigarette group pusher, and the bracket is swingable; during the pushing process, the bracket drives the cigarette group pusher to lower to push the cigarette group, and during the return process, drives the cigarette group pusher to raise to avoid subsequent cigarette groups.

[0015] As a further implementation method, the cigarette group pushing device also includes a return guide rail structure, the return guide rail structure includes a guide rail with a raised profile in the middle, a roller is provided on the bracket to cooperate with the guide rail, and the guide rail is equipped with a cylinder. When the cigarette group pusher pushes, the cylinder drives the guide rail to retreat and disengage from the roller.

[0016] As a further implementation method, the cigarette group pusher is equipped with a cylinder that drives its pushing or returning movement, and a safety lock is provided between the cylinder piston and the bracket. The safety lock includes a round head provided at the end of the cylinder piston, a ball provided on the bracket and cooperating with the round head, and a spring sheet that compresses the two to cooperate.

[0017] In a second aspect, the present invention provides a method for operating the mechanical cigar box quantitative pusher according to the first aspect, comprising the following steps:

[0018] The manufactured cigarettes are placed on the conveyor belt of the cigarette conveying device one after another and are conveyed to the cigarette group counting device; the counter outputs a signal to lift the pressing block of the pressing block structure, and the cigarettes are driven by the conveyor belt into the waiting area below the pressing plate, and the counter starts counting until the set number is reached, after which the counter sends a signal to stop the movement of the conveyor belt and causes the pressing blocks of the pressing block structure to descend and press the cigarettes, the block structure pre-compresses a fixed amount of cigarette groups, and then the cigarette group pusher of the cigarette group pushing device pushes the pre-compressed cigarette groups out of the waiting area; after the cigarette groups are pushed out by the cigarette group pusher, the counter sends a signal to cause the conveyor belt to continue running and lift the pressing block again, and cigarettes are input into the waiting area below the pressing plate again, and the block structure pre-compresses and pushes them out again through the cigarette group pusher.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The cigarette conveying device provided in the present invention can be used for conveying cigarettes, and the cigarette group counting device provided can accurately measure the number of cigarettes. The quantitative cigarette groups can be pushed out by the cigarette group pushing device for boxing. The cooperation of multiple devices such as the cigarette conveying device, the cigarette group counting device and the cigarette group pushing device can reduce the cigarette breakage rate, eliminate the quality defects of missing cigarettes, and improve the cigarette boxing efficiency, with a speed of up to 40 boxes / min.

[0021] 2. The present invention has extremely flexible production capabilities. The cigarette conveying device can be adjusted according to the diameter and length of the cigarettes, and can realize the transportation of cigars with different circumferences. It can realize the quantitative function of cigarette groups of 5 cigars, 6 cigars, 8 cigars, 10 cigars, etc.

[0022] 3. The cigarette group counting device of the present invention is equipped with a pressure plate structure. The height of the pressure plate can be adjusted according to the diameter of the cigarettes. The adjustment requirement is to ensure that the pressure plate is 0.5-1mm higher than the cigarette group, thereby ensuring that the cigarettes are closely arranged and do not jump when the cigarette group moves in the X and Y directions.

[0023] 4. The cigarette group counting device of the present invention features a block structure equipped with a cylinder. This block, while forming a holding area between the block and the conveyor belt that can accommodate a set number of cigarette groups, also pre-compresses the cigarette groups. This pre-compression ensures smooth discharge of cigarette groups after they enter the push channel, reducing the likelihood of blockage within the channel and protecting the group pusher.

[0024] 5. The cigarette group pusher provided in the cigarette group pushing device of the present invention cooperates with the return guide rail in such a way that the return guide rail is separated from the contact with the cigarette group pusher roller during the pushing process, so that the cigarette group can be pushed out of the waiting area normally. During the return process, the return guide rail is in contact with the cigarette group pusher roller again. Since the contour of the return guide rail is higher in the middle and lower on both sides, the cigarette group pusher is raised during the return process, which can avoid interference with the subsequent cigarette groups entering the waiting area.

[0025] 6. The cylinder of the cigarette group pusher of this invention is equipped with a mechanical safety lock. The rounded end of the cylinder piston rod is fitted with a ball bearing, and a spring sheet presses against the ball bearing. The friction between the spring sheet and the ball bearing transmits the cylinder's motion to the cigarette group pusher. If the cigarette group pusher is overloaded, the spring sheet disengages from the ball bearing, disconnecting the power transmission and protecting the cigarette group pusher.

DETAILED DESCRIPTION

[0043] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0044] Example 1

[0045] In a typical embodiment of the present invention, referring to Figure 1 As shown, a mechanical cigar box cigarette quantitative pushing device includes a cigarette conveying device 1, a cigarette group counting device 2 and a cigarette group pushing device 3.

[0046] The cigarette conveying device 1 can be used to convey cigarettes 118, and the cigarette group counting device 2 can accurately measure the number of cigarettes 118. The quantitative cigarette groups 202 can be pushed out by the cigarette group pushing device 3 for boxing. The cooperation of multiple devices such as the cigarette conveying device 1, the cigarette group counting device 2 and the cigarette group pushing device 3 can reduce the breakage rate of cigarettes 118, eliminate the quality defects of missing cigarettes 118, and improve the boxing efficiency of cigarettes 118, with a speed of up to 40 boxes / min.

[0047] like Figure 2 As shown, the cigarette conveying device 1 is used to convey cigarettes to the cigarette group counting device 2, and includes a frame 119 and a transmission mechanism, a cigarette block, a cigarette pressing block and a pressing mechanism located thereon.

[0048] The transmission mechanism includes a driving roller 102, a driven roller 113, an idler roller 111, and a drive motor 101 located on a frame 119. The drive motor 101 provides power to the cigarette 118 transmission mechanism. It utilizes variable frequency control to adjust the speed of the cigarette 118 transmission mechanism. The drive motor 101 and driving roller 102 are coaxially connected at 1083. The conveyor belt 112 wraps around the three transmission rollers once before closing. The conveyor belt 112 is made of rubber, which offers a certain degree of wear resistance and toughness. The cigarettes 118 can be transported along the conveyor belt 112.

[0049] There are two cigarette blockers, arranged along the conveying direction of cigarettes 118, with an adjustable distance between them. Their length extends to the cigarette group counting device 2. Specifically, the two cigarette blockers are a first cigarette block 103 and a second cigarette block 105. The lower portion of the cigarette blocker connecting to the frame 119 is a long hole structure. Loosening the first bolt 106, the second bolt 109, the third bolt 114, and the fourth bolt 117 can adjust the distance between the first cigarette block 103 and the second cigarette block 105. If the length of a cigarette 118 changes, the cigarette blockers are moved toward both ends based on the centerline of the frame 119 to ensure that the distance between the two cigarette blockers is 1-2 mm greater than the length of the cigarette 118.

[0050] Two cigarette pressing blocks are provided, also arranged along the conveying direction of the cigarettes 118, in the same direction as the cigarette blocking blocks. However, the difference is that the cigarette pressing blocks are positioned above the cigarettes 118. Specifically, the two cigarette pressing blocks are a first cigarette pressing block 104 and a second cigarette pressing block 107. Under the pressure of the two cigarette pressing blocks, the arranged cigarettes 118 are pressed to prevent them from jumping during conveyance.

[0051] like Figure 2 As shown, each cigarette pressing block is supported by two pressing mechanisms. Specifically, the pressing mechanisms are mounted on a frame 119. The four pressing mechanisms are a first pressing mechanism 108, a second pressing mechanism 110, a third pressing mechanism 115, and a fourth pressing mechanism 116. The first cigarette pressing block 104 is supported by the second and third pressing mechanisms 110, 115, while the second cigarette pressing block 107 is supported by the first and fourth pressing mechanisms 108, 116.

[0052] like Figure 3 As shown, the four clamping mechanisms have the same structure. This embodiment will only describe the first clamping mechanism 108. It has a base 1081, which is bolted to the cigarette block. Two vertical support rods are mounted on the base 1081, which are hingedly connected to a first bracket 1084 via an axis 1083. One end of the first bracket 1084 is connected to a first spring 1082, and the other end is provided with a connecting block 1086, which is connected to the cigarette clamp via a fifth bolt 1085.

[0053] The first spring 1082 is a compression spring. Under the elastic force of the first spring 1082, a vertical upward force F1 is always maintained on the A end of the first bracket 1084, so that the first bracket 1084 rotates around the axis 1083, and a vertical downward force F2 is always maintained at the B end.

[0054] like Figure 4 As shown, the cigarette group counting device 2 is used to receive cigarettes 118 conveyed by the cigarette conveying device 1, and includes a pressing block structure 201, a pressing plate structure 203, a blocking block structure 204 and a counter 205.

[0055] like Figure 5As shown, the pressing block structure 201 includes a pressing block 20110 and an actuator that drives its up and down motion. The pressing block 20110 is located above the conveyor end of the conveyor belt 112. The actuator includes a first cylinder 2012 and guide shafts. The first cylinder 2012 is mounted on a second bracket 2011, which is in an inverted L-shape and mounted on the frame 119 as a support structure for the first cylinder 2012. The piston of the first cylinder 2012 faces upward. The third bracket 2015 is connected to the piston via a sixth bolt 2016. The third bracket 2015 is bolted to a first guide shaft 2018 and a second guide shaft 2019 at each end. These two guide shafts pass through the second bracket 2011 and are connected to the pressing block 20110. The pressing block 20110 is positioned at the bottom of each guide shaft. Driven by the first cylinder 2012, the two guide shafts drive the pressing block 20110 to move up and down.

[0056] A second spring 2017 is mounted on the two guide shafts and supported between the second bracket 2011 and the third bracket 2015. The second spring 2017 is a compression spring. Under the elastic force of the second spring 2017, the first guide shaft 2018 and the second guide shaft 2019 are constantly subjected to a vertical downward force F, thereby ensuring that the pressing block 20110 is always pressed against the cigarette 118, preventing the cigarette 118 from moving.

[0057] The first cylinder 2012 is a single-acting cylinder. When compressed air is introduced into the air inlet 2013, the piston of the first cylinder 2012 moves upward, driving the third bracket 2015 to move upward. Through the transmission of motion, the pressing block 20110 moves upward. At this time, the cigarette 118 is free, and driven by the conveyor belt 112, the cigarette 118 moves to the right.

[0058] When the compressed air is disconnected from the air inlet 2013, the compressed air in the first cylinder 2012 is discharged through the exhaust port 2014, and the piston of the first cylinder 2012 is free. Under the elastic force of the second spring 2017, the pressing block 20110 moves downward to press the cigarette 118. The pressure exerted by the pressing block 20110 on the cigarette 118 depends on the spring force.

[0059] like Figure 6 As shown, the function of the pressing plate structure 203 is to press the cigarette group 202 to ensure that the cigarette group 202 does not jump when moving along the Y direction (all Figure X YZ direction is unified).

[0060] The fourth bracket 2038 is mounted on the frame 119, and a support rod 20311 is mounted on the fourth bracket 2038. The fourth bracket 2038 has a groove, and the support rod 20311 fits into the groove of the fourth bracket 2038. One end of the support rod 20311 is bent and hooked on a first hook 20312 and a second hook 20313, which are mounted on the sixth bracket 20314. The other end has two studs, a first stud 2034 and a second stud 2035, side by side. The lower end of the studs is connected to the pressure plate 2031. The two studs each engage two nuts, for a total of four nuts: a seventh nut 2032, an eighth nut 2033, a ninth nut 2036, and a tenth nut 2037. A fifth bracket 20310 is also provided on the fourth bracket 2038. The fifth bracket 20310 is provided between the groove and the hook. An eleventh bolt 2039 is provided on the fifth bracket 20310. By adjusting the eleventh bolt 2039, the support rod 20311 can be tightened.

[0061] After the support rod 20311 is tightened, the height position of the head of the support rod 20311 is determined. At this time, the height of the pressing plate 2031 is adjusted according to the diameter of the cigarette 118. The adjustment requirement is to ensure that the pressing plate 2031 is 0.5 to 1 mm higher than the cigarette group 202, thereby ensuring that the cigarette group 202 is tightly arranged and does not jump when moving along the X and Y directions.

[0062] When adjusting the height of pressure plate 2031, adjust first stud 2034 and second stud 2035 simultaneously to ensure they are level and at the same height. To adjust, place a measuring rod with the same diameter as cigarette 118 under pressure plate 2031. Place a 0.5mm feeler gauge between the measuring rod and pressure plate 2031. Pull the feeler gauge out. Adjustment is complete when the feeler gauges under first stud 2034 and second stud 2035 are the same tight.

[0063] like Figure 7 As shown, the counter 205 generates an output signal to control the operation of the first cylinder 2012 in the pressing mechanism 201. Taking one cycle as an example, when the pressing mechanism 20110 is lifted, cigarettes 118, driven by the conveyor belt 112, enter the waiting area below the pressing plate 2031. The counter 205 begins counting. According to the counting rules (commonly used cigarette groups are 5, 6, 8, 10, etc.), when the number of cigarette groups 202 reaches the required number, the counter 205 generates a signal, the first cylinder 2012 shuts off the compressed air, and the pressing mechanism 20110 descends to press the cigarettes 118. At this point, no more cigarettes 118 are fed into the waiting area below the pressing plate 2031. Once the cigarette group 202 is formed, it waits for the cigarette group 202 pushing device 3 to operate. After the cigarette group 202 is pushed out by the cigarette group pushing device 3, the pressing mechanism 20110 is lifted again, and cigarettes 118 are once again fed into the waiting area below the pressing plate 2031.

[0064] In this embodiment, the cigarette group counting device cooperates with other devices, so that the entire device itself has extremely flexible production capabilities. The cigarette conveying device can be adjusted according to the diameter and length of the cigarettes, and cigars with different circumferences can be transported. The quantitative function of cigarette groups of 5 cigars, 6 cigars, 8 cigars, 10 cigars, etc. can be realized.

[0065] In this embodiment, a stopper 2041 is provided to pre-compress the cigarette group 202. The function of the pre-compression is to ensure that the cigarette group 202 is smoothly discharged after entering the cigarette pushing channel, reduce the probability of the cigarette group 202 being blocked in the cigarette pushing channel, and thus play a role in protecting the cigarette group pusher 301.

[0066] Second cylinder 20411 is mounted on seventh bracket 2047. Second cylinder 20411 is stationary. Eighth bracket 20410 moves with the piston of second cylinder 20411. Its piston is connected to two guide shafts: third guide shaft 2042 and fourth guide shaft 2043. Stoppers 2041 are mounted at the ends of third guide shaft 2042 and fourth guide shaft 2043. Seventh bracket 2047 is mounted on frame 119 via twelfth and thirteenth bolts 2044 and 2045.

[0067] The block provided in the block structure can, on the one hand, form a waiting area between the end of the conveyor belt and the conveyor belt that can accommodate a set number of cigarette groups, and on the other hand, the block can pre-compress the cigarette groups.

[0068] The second cylinder 20411 has a first A port 2048 and a first B port 2049. The upper end of the second cylinder 20411 is connected to a three-position four-way solenoid valve. When the pressure block 20110 is lifted to allow smoke to enter the waiting area, compressed air is introduced into the first B port 2049 and the first A port 2048 discharges compressed air. The piston of the second cylinder 20411 moves in the opposite direction of X, and the stopper 2041 moves to the left. The stopper 2041 exceeds the smoke pushing channel of the smoke group 202 by 1mm (when the cylinder is in the middle position in the normal state, the lower stopper 20411 is parallel to the smoke pushing channel), that is, the smoke group 202 is pre-compressed by 1mm.

[0069] After the cigarette group pusher 301 in the cigarette group pushing device 3 completes the cigarette pushing action, the cigarette group pusher 301 withdraws to the initial position. In order to prevent the cigarette group pusher 301 from hitting the stopper 2041 during the withdrawal action, compressed air is introduced into the first A port 2048 and the first B port 2049 discharges the compressed air. The piston of the second cylinder 20411 moves to the right, and the stopper 2041 moves in the X direction, and the stopper 2041 withdraws 2 mm.

[0070] like Figure 8 As shown, the cigarette group pushing device 3 includes a cigarette group pushing handle 301 , a cigarette pushing bracket 302 , and a return guide rail structure 303 .

[0071] like Figure 9 As shown, the cigarette group pusher 301 is equipped with a connecting bracket 3011, a pusher base 3012, and a cigarette pusher block 3013. The cigarette group pusher 301 includes the pusher base 3012, the cigarette pusher block 3013, and the connecting bracket 3011. To reduce the mass of the cigarette group pusher 301 and improve its dynamic performance, the pusher base 3012 is perforated to reduce its weight. The cigarette group pusher 301 is the actuator of the method and device for pushing cigarettes 118 from a cigar box.

[0072] To prevent damage to the push channel of the smoke group 202 when it becomes clogged, the smoke group pusher 301 is designed from a relatively low-strength, high-toughness aluminum alloy. If the smoke group pusher 301 is deformed due to a clogged channel, it can be reshaped using simple tools such as a vise or locking pliers.

[0073] like Figure 10 As shown, the cigarette group pusher 301 is installed on the cigarette pushing bracket 302. The cigarette pushing bracket 302 includes several brackets. Specifically, the cigarette group pusher 301 is connected to the tenth bracket 3022 by bolts, the tenth bracket 3022 is connected to the eleventh bracket 3023 by bolts, and the eleventh bracket 3023 is connected to the twelfth bracket 3026 by a pin 3025, so that the eleventh bracket 3023 can rotate around the pin 3025 by a certain angle.

[0074] The twelfth bracket 3026 is connected to the thirteenth bracket 3027 via bolts, the ninth bracket 3021 is connected to the eleventh bracket 3023 via bolts, and the roller 3028 is installed on the ninth bracket 3021 .

[0075] like Figure 11 As shown, the fifteenth bracket 3039 is fixed to the frame 119 by bolts, the third cylinder 3036 is fixed to the fifteenth bracket 3039, the cylinder piston is welded to the return guide rail 3031, and the return guide rail 3031 is slidably installed on the frame 119 through the sixteenth bracket 30310 and the fourteenth bracket 3032 (to achieve reciprocating motion of the return guide rail 3031 along the X direction), and the roller 3028 (fixedly connected to the cigarette pushing bracket 302, only the roller 3028 is marked here) contacts the return guide rail 3031 during the return stroke, and the roller 3028 does not contact the return guide rail 3031 during the pushing stroke.

[0076] The return guide rail 3031 is designed to coordinate the movement of the cigarette group pusher 301. Specifically, when the cigarette group pusher 301 is in the push stroke, the return guide rail 3031 is inoperative. The cigarette group pusher 301 moves in the Y direction without changing its height, effectively pushing the cigarette group 202 out of the channel. When the cigarette group pusher 301 is in the return stroke, the limit of its Y-direction movement has already exceeded the rearmost edge of the pressure plate 2031. At this point, a new cigarette group 202 has already formed. If the cigarette group pusher 301 is not raised during the return stroke, it will interfere with the newly formed cigarette group 202.

[0077] During the pushing process of the cigarette group pusher 301, compressed air is introduced into the second A port 3037 and discharged from the second B port 3038. The piston of the third cylinder 3036 retreats and the return guide rail 3031 moves along the X direction. At this time, the roller 3028 does not contact the return guide rail 3031. In order to increase the retreat speed of the cylinder piston, a tension spring is added at the third hook 3033 and the fourth hook 3035 to always maintain a pulling force along the X direction on the return guide rail 3031.

[0078] During the return stroke of the cigarette group pusher 301, compressed air is introduced into the second B port 3038 and discharged from the second A port 3037. The cylinder piston moves forward and the return guide rail 3031 moves in the opposite direction of X. At this time, the roller 3028 contacts the return guide rail 3031. When the return guide rail 3031 retreats in the opposite direction of Y, it moves along the contour of the guide rail. The cigarette group pusher 301 is first lifted to the middle position and then gradually lowered to the initial height.

[0079] The cigarette group pusher 301 and the return guide rail 3031 provided in the cigarette group pushing device 3 of this embodiment cooperate in such a way that the return guide rail 3031 is separated from the contact with the roller 3028 of the cigarette group pusher 301 during the pushing process, so that the cigarette group 202 can be pushed out of the waiting area normally. During the return process, the return guide rail 3031 re-contacts the roller 3028 of the cigarette group pusher 301. Since the contour of the return guide rail 3031 is higher in the middle and lower on both sides, the cigarette group pusher 301 is lifted up during the return process, which can avoid interference with the cigarette group 202 that subsequently enters the waiting area.

[0080] like Figure 12 As shown, the fourth cylinder 3043 provides power for the pusher of the smoke group 202. The fourth cylinder 3043 is a double-acting cylinder that performs reciprocating linear motion. The fourth cylinder 3043 is bolted to the frame 119. The spring plate 3046 is also bolted to the fourteenth bracket 3032. The fourteenth bracket 3032 is fixedly connected to the pusher of the smoke group 202.

[0081] When compressed air is introduced into the third A port 3041 and discharged from the third B port 3042, the piston rod 3044 moves in the reverse direction Y, driving the cigarette group pusher 301 to retreat. When compressed air is introduced into the third B port 3042 and discharged from the third A port 3041, the piston rod 3044 moves in the Y direction, driving the cigarette group pusher 301 to advance.

[0082] like Figure 12 and Figure 13 As shown, a ball 3047 is located within the rounded end of the piston rod 3044. A spring sheet 3046 presses against the ball 3047. The friction between the spring sheet 3046 and the ball 3047 transmits the motion of the fourth cylinder 3043 to the seventeenth bracket 3048. When the cigarette group pusher 301 is overloaded, the spring sheet 3046 disengages from the ball 3047, disconnecting the power transmission and protecting the cigarette group pusher 301.

[0083] When the piston rod 3044 is disengaged from the ball 3047, the cigarette group 202 pushing device is in a free state and can move freely along the Y direction. At this time, move the seventeenth bracket 3048 and reinsert the round end of the piston rod 3044 into the spring sheet 3046 to achieve reset.

[0084] A fifth guide shaft 3045 is also provided, and the cigarette group pushing device 3 moves along the fifth guide shaft 3045 .

[0085] Example 2

[0086] This embodiment provides a method for operating the mechanical cigar box cigarette quantitative pusher device according to the first embodiment, including the following steps:

[0087] like Figure 14 As shown, the manufactured cigarettes 118 are placed on the conveyor belt 112 of the cigarette conveying device 1 one after another and are conveyed to the cigarette group counting device 2; the counter 205 outputs a signal to lift the pressing block 20110 of the pressing block structure 201, and the cigarettes 118 are driven by the conveyor belt 112 into the waiting area below the pressing plate 2031. The counter 205 starts counting until the set number is reached, and then the counter 205 sends a signal to stop the conveyor belt 112 and lift the pressing block 20110 of the pressing block structure 201. The block structure 204 descends to press the cigarette 118, and pre-compresses a fixed amount of cigarette group 202. Then, the cigarette group pusher 301 of the cigarette group pushing device 3 is used to push the pre-compressed cigarette group 202 out of the waiting area. After the cigarette group 202 is pushed out by the cigarette group pusher 301, the counter 205 sends a signal to make the conveyor belt 112 continue to operate and to lift the pressing block 20110 again. The waiting area below the pressing plate 2031 is fed with cigarettes 118 again. After pre-compression by the block structure 204, it is pushed out again by the cigarette group 202 pusher, and this process is repeated.
