Description

Technical Field

[0001] This invention relates to the field of unpacking machines for thin and medium-length cigarette packs, and particularly to an unpacking machine for thin and medium-length cigarette packs. Background Technology

[0002] Slim cigarettes are placed in boxes and need to be removed for order allocation. Conventionally, this is done manually, with the boxes opened and the cigarettes fed into an order allocation device. This method is inefficient and labor-intensive. To address this issue, the inventor designed a slim cigarette box opening machine (publication number CN117533618A). However, this machine can only open boxes of slim cigarettes and cannot accommodate boxes with different sizes. It has low utilization, high equipment cost, and is difficult to adapt to. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a box opener for slim and medium-sized cigarettes that can be directly adapted to both slim and medium-sized cigarettes without the need for equipment conversion, thereby greatly improving utilization and reducing equipment costs.

[0004] To solve the technical problem addressed by this invention, the technical solution adopted by this invention is as follows: a box-opening machine for thin-walled cigarettes, comprising a center seam opening device, an upper ear opening device, a lower ear opening device, a single-sided flipping upper and lower ear device, and a cigarette-clamping and pushing device. The discharge end of the center seam opening device is connected to the feed end of the upper ear opening device, the discharge end of the upper ear opening device is connected to the feed end of the lower ear opening device, the discharge end of the lower ear opening device is connected to the feed end of the single-sided flipping upper and lower ear device, and the feed end of the cigarette-clamping and pushing device is connected to the discharge end of the single-sided flipping upper and lower ear device. The center seam opening device is used for... The device cuts the tape bonding between the upper and lower ear plates on both sides of the box and sends the box out. The upper ear opening device is used to open the upper ear plate by cutting the tape bonding at both ends of the upper ear plate on both sides of the box and send the box out. The lower ear opening device is used to open the lower ear plate by cutting the tape bonding at both ends of the lower ear plate on both sides of the box and send the box out. The upper and lower ear opening devices have the function of centering the box. The single-sided flipping upper and lower ear device is used to flip open the upper and lower ear plates on one side of the box. The clamping and pushing device is used to clamp the box and extend it towards the side where the upper and lower ear plates are opened to push out the cigarette pack.

[0005] The beneficial effects of this invention are as follows: Compared with the prior art, this invention uses a vertical plate of the upper pusher head attached to a front plate set on the front side of the lower pusher head, which increases the rigidity of the pusher head's pushing part, thereby enabling a smooth and reliable push of the cigarette packs and improving the reliability of the cigarette pushing device. Furthermore, the addition of an upper pusher head guide rod and an upper pusher head linear bearing connected to the two vertical plates increases the lifting and supporting stability of the upper pusher head, avoiding the problem of weak rigidity due to excessive cantilever caused by the original pusher head only having a slider guide rail pair connected to it. This improves the overall pushing rigidity and strength of the pusher head. Moreover, the cylinder has a certain elastic buffering protection function to prevent damage to the cigarette packs. The height-adjustable pusher head can adapt to the pushing of cigarette packs inside boxes of different heights and sizes. When the pushing area is increased, the pushing is more stable. The height can be adjusted according to the size of the cigarette pack, making adjustment convenient and quick. Attached Figure Description

[0050] The present invention will be further described below with reference to specific embodiments.

[0051] Example 1: Refer to Figure 1-44A box-opening machine for thin-walled cigarettes includes a center seam opening device 1, an upper ear opening device 2, a lower ear opening device 3, a single-sided flipping upper and lower ear device 4, and a packing and pushing device 5. The discharge end of the center seam opening device 1 is connected to the feed end of the upper ear opening device 2, the discharge end of the upper ear opening device 2 is connected to the feed end of the lower ear opening device 3, the discharge end of the lower ear opening device 3 is connected to the feed end of the single-sided flipping upper and lower ear device 4, and the feed end of the packing and pushing device 5 is connected to the discharge end of the single-sided flipping upper and lower ear device 4. The center seam opening device 1 is used to bond the upper ear plates 7 and lower ear plates 8 on both sides of the box body 6. The tape is cut and sent out of the box 6. The upper ear opening device 2 is used to open the tape at both ends of the upper ear plates 7 on both sides of the box 6 and send out the box 6. The lower ear opening device 3 is used to open the tape at both ends of the lower ear plates 8 on both sides of the box 6 and send out the box 1. The upper ear opening device 2 and the lower ear opening device 3 have the function of finding the center of the box 6. The single-sided flipping upper and lower ear device 4 is used to flip open the upper ear plate 7 and the lower ear plate 8 on one side of the box 6. The clamping and pushing cigarette device 5 is used to clamp the box 6 and extend into and push out the cigarettes towards the side where the upper ear plate 7 and the lower ear plate 8 are opened.

[0052] Among them, reference Figure 3-8 As shown, the center-opening device includes a width-adjustable centering mechanism 144, a left-opening assembly 101, a right-opening assembly 102, a conveyor 103, and a box-pushing mechanism 105. The left-opening assembly 101 and the right-opening assembly 102 are symmetrically installed on both sides of the central frame assembly 106. The conveyor 103 is installed at the bottom center of the central frame assembly 106. The box-pushing mechanism 105 is installed at the top of the central frame assembly 106. The width-adjustable centering mechanism 144 is installed on both sides of the central frame assembly 106 and below the left-opening assembly 101 and the right-opening assembly 102, used to center the conveyed cigarette boxes 145. It also includes a parking device assembly 104 installed on the conveyor 103, which, through the left-opening assembly, ... Under the movement of the pusher mechanism and the conveyor, the right-slit assembly cuts the center seam tape on the left and right sides of the cigarette box. The parking device assembly acts as a longitudinal limiter, and the width-adjustable centering mechanism acts as a left and right limiter. After the limit is set, it is convenient for the left-slit assembly 101 and the right-slit assembly 102 to perform the action positioning. The width-adjustable centering mechanism is set up to center and press after the cigarette box enters a certain distance. On the one hand, it can adapt to the width centering requirements of different cigarette boxes, reduce equipment costs, and also avoid damage to the cigarette boxes and the cigarettes inside. On the other hand, after the width is adjustable, the cylinder elastically presses and, under the action of the pusher mechanism, it is more conducive to directional and stable movement, and it is more conducive to the cutting blade to stably cut the center seam tape of the cigarette box, improving cutting stability and cutting more thoroughly.

[0053] To simplify the structure, the width-adjustable centering mechanism 144 includes a left centering rod 146 and a right centering rod 147 symmetrically arranged on both sides of the central frame assembly 106. The left centering rod 146 and the right centering rod 147 are respectively fixedly connected to the cylinder rods of the first double-rod telescopic cylinder 148 and the second double-rod telescopic cylinder 149. The cylinder seats of the first double-rod telescopic cylinder 148 and the second double-rod telescopic cylinder 149 are fixedly connected to the central frame assembly 106 through the mounting bracket 150. By directionally pushing the two centering rods relative to each other through the two double-rod telescopic cylinders, the cigarette box can be quickly centered. The width is adjustable, sensitive and fast, the pushing is stable and reliable, and the cylinder clamping is reliable.

[0054] To facilitate the installation of the centering rod, a connecting plate 151 is fixedly connected to the cylinder rod end of the first double-rod telescopic cylinder 148 and the cylinder rod end of the second double-rod telescopic cylinder 149. The two connecting plates 151 are fixedly connected to the left centering rod 146 and the right centering rod 147 respectively. The installation is convenient and quick because the connecting plates are fixedly connected to the centering rod.

[0055] To ensure stable compression of the tobacco box, both the left centering rod 146 and the right centering rod 147 are flat tubes, longer than the length of the tobacco box 145 and higher than the conveying rollers on the conveyor 103. Inclined guide parts 138 are provided at the inlet and outlet ends of the left centering rod 146 and the right centering rod 147 on the side near the tobacco box. The flat tube structure of the centering rods enables stable compression of the tobacco box, thereby ensuring more stable guiding during the cutting process. The inclined guide parts facilitate guiding.

[0056] To facilitate the installation of the double-rod telescopic cylinder and the adjustment of its position, the mounting bracket 150 is an inverted L-shaped structure. Its horizontal plate has four symmetrical strip holes 152. Four bolts are used to fix the bracket to the cylinder seat of the first double-rod telescopic cylinder 148 or the cylinder seat of the second double-rod telescopic cylinder 149 through the four strip holes 152 respectively. The vertical plate of the mounting bracket 150 is fixedly connected to the longitudinal beam of the central frame assembly 106. The L-shaped mounting bracket has a simple structure, stable support, and low cost.

[0057] Among them, reference Figure 9The aforementioned left slit assembly 101 and right slit assembly 102 are arranged symmetrically, each including a slit blade 107 and a pressing wheel assembly 108. Two slit blades 107 are fixedly connected to the blade holder 109, one at the front and one at the back. The two blades perform slit cutting, resulting in a more thorough cut and preventing the first blade from failing to cut properly due to the elasticity of the tape. The blade holder 109 has an L-shaped cross-section with a horizontally inclined groove 127 on its upper surface. The slit blade 107 is placed in the groove 127 and pressed down by a blade pressure plate 128. The bottom surface of the blade pressure plate 128 has a boss with a width smaller than the groove 127, which presses against the upper surface of the slit blade 107. The blade pressure plate 128 is fixedly connected to the blade holder 109 with screws. This blade fixing structure facilitates length adjustment and is easy to adjust. The device is quick and stable with a press-fit mechanism. The blade is tilted for easy cutting of the tape through the center seam. A center seam pressure plate 129 is fixedly connected to the outer end of the blade holder 109. The center seam pressure plate 129 has a strip-shaped through hole 130 on its surface where the tip of the cutting blade 107 extends. The center seam pressure plate facilitates pressing the tape, ensures smooth cutting during the process, and acts as a limiter to prevent excessive cutting depth and damage to the internal tape. Both ends of the center seam pressure plate 129 have outward bending portions to guide the tape during the pressing process and prevent it from jamming the housing 6. The blade holder 109 is telescopically connected to the central connecting rod 111 of the parallelogram mechanism 110 via a blade telescopic mechanism. The pressing wheel assembly 108 is rotatably connected to the roller frame 112. 12 is cantilevered and fixedly connected to the top connecting rod 114 of the parallelogram mechanism 110 via the seat plate 113, with the roller frame 112 and the slit blade 107 in the same direction. A roller assembly is provided to enable rolling movement while the box is pressed, reducing friction. The side connecting rod of the parallelogram mechanism 110 is hinged to one end of the drive cylinder 115, and the other end of the drive cylinder 115 is hinged to the middle frame assembly 106. Working principle: When the drive cylinder extends, the parallelogram mechanism swings, thereby driving the roller assembly to press down. When it presses to the top of the box, the blade extension mechanism extends the blade, and the blade tip engages with the tape. Under the push of the box-pushing mechanism, the center seam is cut. The roller assembly, the two side center seam pressing plates, the conveyor rollers, and the width adjustable centering are all included. Under the comprehensive guiding effect of the mechanism, the cutting process is more stable, avoiding the problem of poor cut quality caused by shaking, and the cut is more precise. The parallelogram mechanism works in tandem, achieving precise vertical center positioning of the blade connected in the middle while pressing, greatly simplifying the structure. To enhance the swing stability of the parallelogram mechanism 110, a second parallelogram mechanism 131 is connected in parallel to the outside of the parallelogram mechanism 110. The two top hinge points of the second parallelogram mechanism 131 are hinged to the two side connecting rods of the parallelogram mechanism 110 through the hinge shaft 132. The second parallelogram mechanism 131 swings with the parallelogram mechanism 110. With the auxiliary reinforcement of the second parallelogram mechanism 131, the swing is more stable.The pressing mechanism ensures greater stability of the housing. The second parallelogram mechanism 131 is lower than the blade telescopic mechanism, preventing interference during its extension and retraction. The lower ends of the connecting rods on both sides of the parallelogram mechanism are hinged to the portal-shaped main support. Each lower end of the portal-shaped main support is secured to the crossbeam of the central frame assembly 106 by two screws, with each screw locked in place by two nuts, allowing for height adjustment. The connecting rods on both sides of the second parallelogram mechanism 131 are hinged to an auxiliary mounting plate, which is fixedly connected to one side of the portal-shaped main support.

[0058] The aforementioned blade extension mechanism includes a guide mounting plate 116, a blade guide shaft 117, and a telescopic cylinder 118. The guide mounting plate 116 has a horizontal strip hole facing the blade groove 127 to increase the blade extension adjustment range. The blade holder 109 is fixedly connected to the guide mounting plate 116. Two blade guide shafts 117 are used, with the same end fixedly connected to both sides of the guide mounting plate 116. The blade guide shafts 117 are connected to the central connecting rod 111 through two linear bearings 119. The cylinder rod of the telescopic cylinder 118 is fixedly connected to the connecting lug in the middle of the top side of the guide mounting plate 116. The cylinder seat of the telescopic cylinder 118 is fixedly connected to the side of the central connecting rod 111 through an L-shaped cylinder bracket 133. The telescopic cylinder pushes the guide mounting plate to move, thereby realizing the position movement of the blade holder, so that the center seam blade can be inserted into the center seam tape on the side of the box. The linear bearings provide precise guidance, and the extension is smooth and reliable.

[0059] Among them, reference Figure 10 As shown, the aforementioned push-box mechanism 105 includes a push plate 120 and a rodless cylinder assembly 121. The push plate 120 is connected to the bottom of the slider of the rodless cylinder assembly 121 via a slide plate assembly 122. A top plate is fixedly connected to the rear side of the push plate 120 via two stiffeners. The push plate 120 is vertically suspended and hinged to a connecting lug 124 provided at the bottom of the slide plate assembly 122. A vertical baffle 125 is provided on the front side of the connecting lug 124. An elastic protective layer 126 is provided on the rear end face of the vertical baffle 125, which abuts against the top plate on the rear side of the push plate 120. The vertical baffle 125 rotates freely around its hinge axis without interfering with the vertical baffle. The elastic protective layer 126 can play a role in shock absorption and noise reduction. The rodless cylinder assembly 121 is installed on the top of the middle frame assembly 106 through the fixed hangers 123 at both ends. When the box needs to be pushed into the conveyor, the push plate automatically rotates inward during the pushing process. When the box moves to the baffle position of the parking device assembly, the push plate automatically falls down. The center seam cutting action on both sides presses the box tightly and the blade extends into the center seam tape. The rodless cylinder is controlled to contact the push plate with the box and push it backward. Under the pressing action of the center seam blade and roller group, the center seam is cut smoothly. After the center seam is cut, the box is pushed into the next station.

[0060] Reference Figure 11-12As shown, the conveyor 103 includes multiple rollers 134, a conveyor frame 135, and a conveyor motor 136. The multiple rollers 134 are evenly spaced and rotated on the top of the conveyor frame 135. Adjacent rollers 134 are connected and driven by a multi-wedge belt 137. One of the rollers 134 is connected to the motor shaft of the conveyor motor 136 through the multi-wedge belt. The conveyor motor 136 is installed inside the conveyor frame 135. Driven by the conveyor motor 136, all rollers are driven to rotate in one direction. The parking device assembly 104 includes an L-shaped baffle 139 and a limiting telescopic cylinder 140. The baffle 139 is fixedly connected to the upper ends of two stop-start guide rods 141. The two stop-start guide rods 141 are connected to a crossbeam 143 through a stop-start linear bearing 142. The crossbeam 143 is fixedly connected to the conveyor frame 135. The cylinder rod of the limiting telescopic cylinder 140 is fixedly connected to the middle of the baffle 139. The two stop-start guide rods 141 are arranged on both sides. The cylinder seat of the limiting telescopic cylinder 140 is fixedly connected to the crossbeam 143. By the action of the limiting telescopic cylinder, the baffle is controlled to extend or retract in the direction of the roller 134, thereby realizing the parking and opening of the box. The baffle has an L-shaped cross section and good rigidity.

[0061] Among them, reference Figure 13-17As shown, the upper ear opening device 2 includes an upper ear centering and cutting assembly 201, a pressure plate 202, and a second-station conveyor 203. The upper ear centering and cutting assembly 201 is installed on the upper ear centering frame 228 and is used to press the lower ear plates 8 on both sides of the housing 6 and cut the tape on both sides of the upper ear plate 7. Two vertical connecting arms 239 are provided at the left and right ends of the upper ear centering frame 228. The two vertical connecting arms 239 are connected to the upper ear frame assembly 204 through the upper ear lifting linkage drive mechanism. The pressure plate 202 is connected to the upper ear lifting linkage drive mechanism. The actuator and the upper ear centering frame 228 work together to center and lock the box body through cutting. The pressure plate 202 is vertically slidably connected to the top of the upper ear frame assembly 204. The second station conveyor 203 is installed in the middle of the bottom side of the upper ear frame assembly 204. The upper ear centering and cutting assembly 201 centers the box body and cuts the tape at both ends of the upper ear plate on both sides. The pressure plate cylinder presses down on the box body to prevent shaking or movement. The second station conveyor 203 transports the box body and has the same structure as the first station conveyor, and also includes a second The parking device assembly 212, which has the same structure as the first parking device assembly 104, is installed on the second station conveyor 203 and extends out of the roller gap of the second station conveyor 203 for a limit stop. When the box is conveyed by the second station conveyor and reaches the second parking device assembly 212, it is limited. The upper ear lifting linkage drive mechanism drives the pressure plate 202 to descend and drives the upper ear centering and cutting assembly 201 to descend in a linkage manner to center and press the box 6. The upper ear centering and cutting assembly is controlled to align and fix the upper ear plate and glue both ends. After the cutting is completed, the control linkage pressure plate 202 rises and drives the upper ear centering cutting component 201 to rise and release the centering box 6, and retract the limit of the second parking component 212. Under the power of the second station conveyor 212, it enters the next station (the lower ear opening device opens the lower ear). The upper ear lifting linkage drive mechanism is used to link the upper ear centering cutting component and the pressure plate 1 (same as above and below) to realize the centering of the box, which facilitates the centering and adsorption of the upper ear and adapts to the needs of different box height changes.

[0062] Specifically, the upper ear lifting linkage drive mechanism includes an upper ear vertical slider guide rail pair 240, a frame lifting drive arm 241, a drive shaft 242, a pressure plate lifting drive arm 243, a pressure plate lifting guide rod 244, and an upper ear lifting power mechanism 245. The two ends of the drive shaft 242 are rotatably connected to the inner top of the upper ear frame assembly 204 via bearing seats. Two vertical connecting arms 239 are connected to both sides of the upper ear frame assembly 204 via two upper ear vertical slider guide rail pairs 240. Two symmetrically arranged frame horizontal slide grooves 246 are fixedly connected to the upper ends of the two vertical connecting arms 239. The grooves of the two frame horizontal slide grooves 246 are arranged horizontally relative to each other. Two frame lifting drive arms 243 are used, with one end symmetrically fixed via a sleeve connection (using screw locking). A frame drive roller 233 is rotatably connected to a drive shaft 242 at one end and a frame drive roller 233 at the other end. The frame drive roller 233 is placed in a frame horizontal slide groove 246 and can move within the frame horizontal slide groove 246. The frame lifting drive arm 241, which rotates around the drive shaft 242, can drive the two vertical connecting arms 243 to move up and down along the upper ear vertical slider guide rail pair 240. One end of the pressure plate lifting drive arm 243 is fixedly connected to the middle of the drive shaft 242 and is parallel to the frame lifting drive arm 241 on the same side of the drive shaft 242. The length of the frame lifting drive arm 241 is half the length of the pressure plate lifting drive arm 243. That is, when the box is pressed together: when the pressure plate 202 descends a distance of 2H, the upper ear is aligned with the middle frame. The frame 228 descends a distance H to open the housing. When the housing is released, the pressure plate 202 and the upper ear centering frame 228 rise and move in opposite directions. The other end of the pressure plate lifting drive arm 243 is rotatably connected to a pressure plate drive roller 247. The top surface of the pressure plate 202 has a horizontal sliding groove 234, which consists of two symmetrical strip-shaped through holes located on the two side walls along the length of the upper-opening strip-shaped groove. The pressure plate drive roller 247 is symmetrically positioned within the two strip-shaped through holes of the horizontal sliding groove 234. Two pressure plate lifting guide rods 243 are symmetrically fixed to the front, rear, and center of the top surface of the pressure plate 202. These guide rods are connected via a pressure plate lifting linear bearing 235. At the top of the upper ear frame assembly 204, the pressure plate lifting drive arm 243, which rotates around the drive shaft 242, can drive the pressure plate 202 to move up and down along the pressure plate lifting guide rod 244. The drive shaft 242 is connected to the upper ear lifting power mechanism 245 that drives its rotation. The upper ear lifting power mechanism 245 is mounted on the top of the upper ear frame assembly 204 and includes an upper ear drive motor 236 and a double-row sprocket transmission mechanism 237. The upper ear drive motor 236 is fixedly connected to the top of the upper ear frame assembly 204. The driving double-row sprocket of the double-row sprocket transmission mechanism 237 is fixedly connected to the motor shaft of the upper ear drive motor 236, and the driven double-row sprocket of the double-row sprocket transmission mechanism 237 is fixedly connected to the drive shaft 242.It adopts a double-row chain drive, providing ample power to ensure the power requirements and transmission stability for lifting, pressing, and other functions.

[0063] The working principle of the upper ear lifting linkage drive mechanism is as follows: When it is necessary to press the box 1, the box stops on the supporting conveyor (the second station conveyor 203, and the lower ear lifting linkage drive mechanism is the third station conveyor). The upper ear lifting power mechanism drives the rotating shaft to rotate, and the pressure plate lifting drive arm 243 drives the pressure plate 202 to descend along the pressure plate lifting guide rod 244 until it is pressed against the top surface of the box. At the same time, the frame lifting drive arm 241 synchronously drives the upper ear centering frame 228 to descend, so that the upper ear centering cutting component 201 descends synchronously, and finally ensures that the suction cup adsorbs the ear plate of the box (the pressure plate descends 2H, and the upper ear centering cutting component 201 descends H). After the box is finally pressed, the adsorption and cutting of the ear plate are completed by the upper ear centering cutting component 201.

[0066] Among them, reference Figure 18-24The lower ear opening device 3 includes a lower ear centering and cutting assembly 301, a second pressure plate 302, and a third-station conveyor 303. The lower ear centering and cutting assembly 301 is installed on the lower ear centering frame 328 and is used to press the upper ear plates 7 on both sides of the box 6 and remove the tape on both sides of the lower ear plates 8. Two vertical connecting arms 335 are provided at the left and right ends of the lower ear centering frame 328. The two vertical connecting arms 335 are connected to the lower ear frame assembly 304 through the lower ear lifting linkage drive mechanism. The second pressure plate 302 is connected to the lower ear lifting linkage drive mechanism and moves in conjunction with the lower ear centering frame 328 to center and lock the box for cutting.

The third-station conveyor 303 is installed in the middle of the bottom side of the lower ear frame assembly 304. The second pressure plate 302 is connected to the first pressure plate 202. Similar to the first parking assembly 312, it also includes a third parking assembly 312, which is installed on the third station conveyor 303 and extends out of the roller gap of the third station conveyor 303. When the box 6 is conveyed by the third station conveyor 312, it reaches the third parking assembly 312 and is limited. The lower ear lifting linkage drive mechanism controls the lower plate 302 to descend and the third station conveyor to descend to press the box. The lower ear centering cutting assembly is controlled to align and fix the lower ear plate and cut the tape at both ends. After the cutting is completed, the pressure plate cylinder assembly is controlled to release the box and retract the limit of the third parking assembly. Under the power of the conveyor, it enters the next station. The lower ear lifting linkage drive mechanism is used to link the lower ear centering cutting assembly and the pressure plate ear (same as above and below) to realize the centering of the box, which facilitates the centering and adsorption fixation of the lower ear and adapts to the needs of different box heights.

The length of the frame lifting drive arm 337 is half the length of the pressure plate lifting drive arm 339, that is, when the box is pressed together, the frame lifting drive arm 337 is also connected to the drive shaft 338. When the pressure plate 302 descends a distance of 2H, the lower ear centering frame 328 descends a distance of H, realizing the housing. When the housing is released, the pressure plate 302 and the upper ear centering frame 328 rise and move in opposite directions. The other end of the pressure plate lifting drive arm 339 is rotatably connected to the pressure plate drive roller 348. The top surface of the pressure plate 302 is provided with a pressure plate horizontal slide groove 344.

The push plate 308 can push the upper ear and its housing inward to avoid affecting the movement of the scrubbing blade. After pressing, it is easier to form a gap with the suction cup, which facilitates the entry of the scrubbing blade and increases the scrubbing blade's movement space.

[0069] The working principle of the lower ear centering cutting component 301 is similar to that of the upper ear centering cutting component 301: When the box reaches the position of the third stopper component, the third station conveyor is stopped, the pressure plate 2 302 is started to press the box, the lifting component 2 309 is controlled to be in the lowest position and the longitudinal movement component 2 is controlled to make the two scribers 2 in the innermost position, the lateral movement component 2 is controlled to press the push plate 2 to the lower ear parts on both sides of the box, the suction cup extension component 2 is controlled to move to suction the upper ear and pull it outward, forming a cavity between the upper ear and the box, the lifting component 2 309 is controlled to rise, allowing the scribers 2 to enter the cavity, the longitudinal movement component 2 is controlled to move the two scribers 2 outward to cut the tape on both sides of the upper ear, after the cutting is completed, the scribers are controlled to return along the original path, exit the push plate 2, the pressure plate 2 is released, the limit of the third stopper component is released, and under the action of the third station conveyor, it is sent to the next process.

Furthermore, it includes a fourth stop assembly 427, which has the same structure as the first stop assembly and is installed on the fourth station conveyor 403 and extends from the fourth... The roller gap extension limiter of the workstation conveyor 403 stops the box when it reaches the fourth parking device assembly 427 under the conveyor of the fourth workstation. The four workstation conveyors then extend two auxiliary telescopic positioning components 432 to initially position the box. Then, the single-sided flap telescopic abutment plate assembly 428 is extended to push the box towards the auxiliary telescopic positioning component 432. Finally, the pressure plate cylinder assembly presses down on the box, retracting the auxiliary telescopic positioning component 432 and the single-sided flap telescopic abutment plate assembly. The plate assembly 428 and the flap opening and pressing mechanism 401 open and press the upper and lower flaps (upper flap plate 7 and lower flap plate 8) of the box 6 that need to be opened, forming an outward V-shape. After the upper and lower flaps are opened, the control plate cylinder assembly releases the box and retracts the limit of the fourth stop assembly, and starts the fourth station conveyor. Under its conveying power, the box on the side with the upper and lower flaps in the open state enters the upper and lower flap limiting mechanism of the next station.

The push plate 405 has two pairs of guide plates 406 on both its upper and lower sides, facing the telescopic lifting mechanism 408. The upper and lower guide plates 406 are inclined towards the horizontal center of the push plate 405 to facilitate access to the upper and lower flaps of the housing. The pressing guide plate 407 is fixedly connected to the cylinder rod of the lower guide plate telescopic cylinder 409. The inner end of the pressing guide plate 407 has a sloping structure, which better fits the lower flap of the single-sided upper and lower flaps, which are shaped like an "8". The cylinder seat of the lower guide plate telescopic cylinder 408 is horizontally fixedly connected to the flap frame assembly 404 via a cylinder bracket 410. Structure 408 includes a push plate horizontal guide rod 411, a lead screw and nut pair 412, an ejector motor 413, a power mounting plate 414, a push plate vertical guide rod 415, and a push plate vertical cylinder 416.

An arc-shaped tail pull plate 422 is fixedly connected between the upper ends of the two vertical push plate guide rods 415. The arc-shaped structure facilitates the installation of the vertical push plate cylinder 416 and avoids interference. The two vertical push plate guide rods 415 are connected to both sides of the horizontal plate 420 along its length direction via linear bearings. The horizontal plate 420 is fixedly connected to the support assembly 421, which is fixedly connected to the flap frame assembly 404.

The support assembly 421 includes two support members 422 and two support members. The second support 423 and two third support 424 are fixedly connected by a horizontal plate 420 between the two first support 422. Each first support 422 is in the shape of an angle steel, with a reinforcing rib on one side of the inner corner, and is fixedly connected to a second support 423. The two second support 423 are fixedly connected by a reinforcing horizontal beam 426. The second support 423 is a vertical beam structure, with both ends fixedly connected to the fourth support 425 and the third support 424 respectively. The fourth support 425 is fixedly connected to the top of the flap frame assembly 404. The third support 424 is an inverted L-shaped structure, with its lower end fixedly connected to the side horizontal beam of the flap frame assembly 404. The vertical cylinder 416 of the push plate drives the power mounting plate to move up and down, thereby driving the power telescopic mechanism mounted on the power mounting plate to move up and down.This, in turn, causes the push plate to move up and down. Driven by the power telescopic mechanism, the push plate extends and retracts. As the entire device moves up and down and back and forth, the push plate enters the inner side between the upper and lower ears. By pressing down on the lower ear guide plate, the lower ear is limited, and the push plate limits the upper ear, thus opening the upper and lower ears.

[0076] Working principle of the single-sided flip-up and down-down ear device 4: When the guide ear plate 407 is pressed down, it is in the retracted state. The push plate 405 and the guide ear plate 406 are in the front end and vertical middle positions. After the upper and lower ears of the box are cut, they are sent to the single-sided flip-up and down-down ear device station. The upper and lower ears of one side of the box will be placed on the guide ear plate 406 under the guidance of the push plate 405 and the guide ear plate 406. The fourth parking device assembly 427 is in the extended state. Under the power transmission of the fourth station conveyor, when it reaches the fourth parking device assembly 427, it is limited and the fourth station conveyor stops. The pressure plate cylinder assembly 402 is activated to press the box and control the extension and retraction of the single-sided flip-up ear abutment plate assembly 428 to extend. The abutment plate rests against the side of the housing without the upper and lower ears open, and the push plate 405 is moved down a certain distance to ensure that the lower ear can be opened and limited after the guide plate 407 is pressed out. After completion, the push plate is moved up, and the upper ear is opened under the action of the guide plate 406, so that the upper ear is also in the open state, forming an outward V-shape with the lower ear. At this time, the abutment plate is retracted, the pressure plate cylinder assembly 402 is released, and the limit of the fourth stop assembly is retracted. Under the action of the fourth station conveyor, the housing with the upper and lower ears in the open state is sent to the next station. The open upper and lower ears are kept in the open state under the limit of the upper and lower ear limit mechanism of the next station.

[0077] Among them, reference Figures 31-44The cigarette pushing and clamping device 5 includes a cigarette pushing mechanism assembly 501, a top clamping mechanism 502, a fifth-station conveyor 503, and a buffer belt conveyor unit 504. The buffer belt conveyor unit 504 and the cigarette pushing mechanism assembly 501 are respectively arranged on the left and right sides of the cigarette pushing frame assembly 505. The cigarette pushing mechanism assembly 501 can push the cigarette packs out of the box 6 and feed them onto the buffer belt conveyor unit 504. The buffer belt conveyor unit 504 is composed of two sets connected together, and a first vertical baffle mechanism 574 is provided at the connection point. The two sets of buffer belt conveyor units 504 are connected together. 04 can buffer two independent cartons of cigarettes, thus increasing the buffer capacity. The top clamping mechanism 502 and the fifth station conveyor 503 are respectively installed at the top and bottom middle of the cigarette pushing frame assembly 501. The top clamping mechanism 502 is used to clamp the front and rear ends of the box 1 placed on the fifth station conveyor 503. The fifth station conveyor 503 has the same structure as the first station conveyor 103, and also includes a fifth stop assembly 526 and an upper ear limiting mechanism. The fifth stop assembly 526 has the same structure as the first stop assembly and is installed on... The upper ear limiting mechanism extends and is limited from the roller gap of the fifth station conveyor 503. It includes a smoke-pushing inlet guide rod 527, which is fixedly connected to the dual-shaft end of the vertical telescopic dual-shaft cylinder 528 via an inlet push rod plate 529. The cylinder seat of the vertical telescopic dual-shaft cylinder 528 is fixedly connected to the smoke-pushing frame assembly 505 via a connecting seat 530. The smoke-pushing inlet guide rod 527 keeps the upper ear, which was opened in the previous process, in an open state. The end facing the previous process has an outward arc-shaped bending structure, which serves as a guide. When the box is conveyed by the fifth station conveyor, it is stopped at the fifth stop assembly 526. The fifth station conveyor stops, and the front and rear ends of the box are clamped by the top clamping mechanism 502. The cigarette pushing mechanism assembly 501 pushes the cigarettes out of the box 6. Two buffer belt conveyor units and the first vertical baffle mechanism are added for limiting and blocking isolation, which can buffer two boxes of cigarettes, ensuring the continuity of subsequent sorting and processing, and the production cycle is not affected, resulting in high sorting efficiency.

[0078] like Figure 36As shown, the first vertical baffle mechanism 574 includes a first smoke baffle plate 575, a smoke baffle slide 576, a rodless cylinder 577, a smoke baffle guide rod 578, and a smoke baffle linear bearing 579. The first smoke baffle plate 575 has two sets of upper limit grooves 580 and lower limit grooves 581 embedded on its vertical sides. The two sets of upper limit grooves 580 and lower limit grooves 581 are respectively fixedly connected to both sides of the smoke pushing frame assembly 505 and located on the upper and lower sides of the belt of the buffer belt conveyor unit 504. The bottom of the first smoke baffle plate 575 is fixedly connected to the horizontal strip-shaped smoke baffle slide 576. The middle part of the smoke baffle slide 576 is fixedly connected to the cylinder seat of the rodless cylinder 577. The two ends of the cylinder rod of the rodless cylinder 577 are vertically fixedly connected to the baffle frame 583 through the rodless cylinder seat 582. The baffle frame 583 is fixedly connected to the smoke pushing frame assembly 505, thus baffled the smoke. Two guide rods 578 are used, which are connected to the two ends of the smoke baffle slide 576 near one side through two smoke baffle linear bearings 579 respectively. The two ends of the smoke baffle guide rods 578 are vertically fixed to the baffle frame 581 through guide rod seats 580. Two limit seats 584 are fixedly connected to the top of the smoke baffle slide 576. The baffle frame 581 is fixedly connected to the limit seats 584 near the bottom and to the limit posts 585. After the limit seats are lowered, they will rest on the limit posts. By controlling the rodless cylinder 577, the first smoke baffle 575 is pushed to move in a directional direction in the limit groove, which can realize the single-box strip buffer of the first buffer belt conveyor unit, prevent the entry of the buffer belt conveyor unit, and play the role of isolating the two smoke boxes. The limit groove plays the role of directional reinforcement of the smoke baffle, and the limit seats 582 and the limit posts play the role of limiting the descent of the smoke baffle.

[0079] Reference Figure 37-41 As shown, the cigarette pushing mechanism assembly 501 includes a height-variable push head 506, a push head guide rod 508, a linear bearing 509, a support base 510, and a push head cylinder 507; the height-variable push head 506 includes an upper push head 532 and a lower push head 531; wherein, the lower push head 531 includes a base plate 5310, a front side plate 5311, a rear side plate 5312, and two upright plates 5313, the front side plate 5311 and the rear side plate 5312 are respectively fixedly connected to the front and rear ends of the base plate 5310, the two upright plates 5313 are fixedly connected to the two ends of the front side plate 5311 and the rear side plate 5312 and are fixedly connected to the base plate 5310, the two upright plates 5313 are provided with weight reduction holes 5314, and the rear side plate 5312 is provided with through holes for wires and air pipes to extend into. The lower push head of this structure has high support stability;

[0080] The upper pusher head 532 is an inverted L-shaped plate. Its top plate bottom is connected to two upper pusher head linear bearings 587 via two vertical upper pusher head guide rods 586 and to the lower pusher head 531 via a lifting drive mechanism. The upper pusher head linear bearings 587 are fixedly connected to the inner side of the vertical plates 5313 set on the left and right sides of the lower pusher head 531. The vertical plate of the upper pusher head 532 is attached to the front side plate 5311 set on the front side of the lower pusher head 531. The lifting drive mechanism is installed on the lower pusher head 531 and can drive the upper pusher head 532 to move up and down. During the lifting and lowering process, the vertical plate of the upper pusher head 532 always keeps in contact with the front side plate 5311 (the maximum lifting amount can ensure that partial contact and overlap are always maintained), which improves the rigidity and pushing stability of the cigarette pack.

[0081] Four pusher guide rods 508 are used, with one end symmetrically fixedly connected to the rear side plate 5312 located near the four corners on the rear side of the lower pusher 531; four linear bearings 509 are used, correspondingly sleeved on the four horizontally arranged pusher guide rods 508; the support base 510 is fixedly connected to the four linear bearings 509; the cylinder rod of the pusher cylinder 507 is fixedly connected to the rear side plate 5312 through a flange fixedly connected to it, the cylinder seat of the pusher cylinder 507 is fixedly connected to the support base 510, and the support base 510 is fixedly connected to the smoke pusher support frame 511.

[0082] During the process of pushing out cigarette packs opened on one side, the inventors found that the existing variable lifting pusher head with a comb-tooth structure was prone to jamming, making it difficult to achieve stable pushing. Therefore, improvements were made by attaching the vertical plate of the upper pusher head to the front plate set on the front side of the lower pusher head. This increases the rigidity of the pusher head's pushing part, thereby enabling a smooth and reliable pushing of the cigarette packs and improving the pushing reliability of the cigarette pushing mechanism. Furthermore, the upper pusher head guide rod and upper pusher head linear bearing are added to connect to the two vertical plates, increasing the lifting and supporting stability of the upper pusher head and avoiding the excessive cantilever and weak rigidity caused by the original upper pusher head only being connected by a slider guide pair. This design addresses the issue of inconsistent pusher head height, thereby improving the overall pushing rigidity and strength of the pusher head. Furthermore, the cylinder provides elastic buffering protection to prevent damage to the cigarette packs. The height-adjustable pusher head can adapt to pushing out cigarette packs from boxes of varying heights and sizes. Increasing the pushing area results in more stable pushing. The height can be adjusted according to the size of the cigarette box, making adjustment convenient and quick. The 507 pusher head cylinder drives the variable pusher head to move along the pusher head guide rod and pusher head linear bearing, entering the box to push out the cigarette packs. The movement is smooth and reliable. The height-adjustable pusher head enables pushing out cigarette packs from boxes of varying heights, reducing costs, increasing the contact area, and making pushing more stable.

[0083] Specifically, the lifting drive mechanism includes a lifting pusher cylinder 588, a vertical sliding plate 589, a vertical linear slider guide rail pair 534, a pusher screw and nut pair 535, a belt drive mechanism 536, and a lifting drive motor 537. The lifting pusher cylinder 588 is a dual-shaft cylinder, with its two output shafts fixedly connected to the bottom of the horizontal plate of the upper pusher 532 via a flange 533. The cylinder seat of the lifting pusher cylinder 588 is fixedly connected to the front side of the vertical sliding plate 589. The slider of the vertical linear slider guide rail pair 534 is fixedly connected to the rear side of the vertical sliding plate 589, and the guide rail of the vertical linear slider guide rail pair 534 is fixedly connected to the rear plate 5312. The pusher screw and nut pair 535... The screw nut of 535 is fixedly connected to the rear side of the vertical sliding plate 589. The two ends of the screw of the push head screw nut pair 535 are rotatably connected to the front side of the rear plate 5312 through bearing seats. The driven pulley of the belt drive mechanism 536 is fixedly connected to the lower end of the screw of the push head screw nut pair 535 that extends out of the bearing seat. The motor shaft of the lifting drive motor 537 is fixedly connected to the driving pulley of the belt drive mechanism 536. The housing of the lifting drive motor 537 is fixedly connected to the base plate 5310 of the lower push head 531 through the motor frame. Through the double lifting formed by the lifting push head cylinder and the screw nut, the lifting height is higher, which can adapt to the pushing of cigarette packs stacked in higher boxes, and the pushing is more stable and reliable. Specifically, an elastic rubber limit post 538 is installed directly below the slider of the vertical linear slider guide rail pair 534. The rubber limit post 538 is fixedly connected to the base plate of the lower push head. The elastic rubber limit post 538 prevents the slider from falling off the guide rail during the descent and plays an elastic buffer protection role. The vertical sliding plate 589 is fixedly connected to the slider of the vertical linear slider guide pair 534 via a pad. The rear side plate 5312 and the front side plate 5311 are fixedly connected at both ends via a vertical plate 5313.

[0084] Rubber pusher head 1 590 and rubber pusher head 2 591 are fixedly connected to the front side of the vertical plate of the upper pusher head 531 and the lower front side of the front plate 5311 of the lower pusher head 532, respectively. Rubber pusher head 1 590 and rubber pusher head 2 591 are fixedly connected to the front side of the vertical plate of the upper pusher head 531 and the front side of the front plate 5311 of the lower pusher head 532 respectively through two columns. During the process of pushing the cigarette pack, the rubber heads avoid damaging the cigarette pack shell. The column connection realizes a suspended structure, which is more conducive to playing an elastic buffer role. Rubber pusher head 1 590 and rubber pusher head 2 591 are provided with a sloping surface 592 facing the side of the box, which facilitates the guiding role. To ensure smooth cigarette ejection and avoid the impact of the lower ear resetting, an inlet lower ear pressing limit plate 539 is installed below the cigarette pushing mechanism assembly 501. The inlet lower ear pressing limit plate 539 is fixedly connected to the cylinder rod connecting plate 541 of the lower ear limiting directional telescopic cylinder 540. The cylinder seat of the lower ear limiting directional telescopic cylinder 540 is fixedly connected to the cigarette pushing support frame 511 through the cylinder seat bracket 542. The inlet lower ear pressing limit plate 539 faces the previous process section and opens outward to facilitate its guiding function, allowing the lower ear opened in the previous process to continuously enter the current station and remain open. The open lower ear avoids the impact during the cigarette ejection process and the problem of difficulty in maintaining downward tilting due to its own weight.

[0085] Reference Figures 42-44As shown, the top clamping mechanism 502 includes two clamping plates 512, which are vertically fixed to the bottom of two horizontal hanging plates 513. Both clamping plates 512 have a rubber layer 543 on their inner sides, which increases friction and makes clamping more stable and reliable. Reinforcing ribs are provided on the back of both clamping plates 512 to improve clamping rigidity. Both hanging plates 513 are connected to the front and rear parts of the upper surface of the lifting main plate 515 via a slider guide pair 514. The lifting main plate 515 has a U-shaped notch 502 larger than the width of the clamping plate corresponding to the clamping plate 512. 16. The lifting main board 515 is fixedly connected to the upper pull plate 518 via four lifting rods 517. The upper pull plate 518 is connected to the clamp bracket 520 via the clamp lifting assembly 519. The clamp bracket 520 is a gantry structure, with its two lower ends fixedly connected to the top of the smoke pushing frame assembly 505. It also includes side ear suction cups 521 for adsorbing and pushing material side ears. Two sets of side ear suction cups 521 are provided, and each set of side ear suction cups 521 is fixedly connected to the connecting seat 522. The connecting seat 522 is an inverted L-shape, with its upper free end fixedly connected to the lower end of the inverted L-shaped crank arm shaft 523. The upper free end of 523 is connected to the rotary cylinder 525 via a flange shaft 524. The rotary cylinder 525 is fixedly connected to the bottom of the extension section of the hanging plate 513 facing the cigarette pushing mechanism. The rotary cylinder is controlled to rotate. When the suction cups adhere to the two ears, the rotary cylinder is controlled to rotate in the opposite direction to open the two ears, thereby reducing the obstruction force during the pushing of the cigarette and providing pushing stability and reliability. The clamp lifting assembly 519 includes a clamp lifting cylinder 544, a clamp lifting guide rod 545, and a clamp mounting plate 546. The cylinder rod of the clamp lifting cylinder 544 is hinged to the upper pull plate 5.

The feed end of the buffer belt conveyor unit 504 is provided with a cantilevered transition plate 567 with the belt flush with it. The transition plate 567 facilitates docking with the fifth station conveyor, thereby feeding the pushed-out cigarette packs into the buffer belt conveyor unit 504.A transition plate 567 facing the fifth station conveyor is equipped with an outlet pressing limit plate 568.
