Description

Technical Field

[0001] This invention relates to the field of case opening machine technology, and in particular to a center-seam opening device for opening cases of slim cigarettes. Background Technology

[0002] Slim cigarettes are placed in boxes and need to be removed for order allocation. Conventionally, they are opened manually and sent to an order allocation device for distribution. This method is inefficient and labor-intensive. To address this problem, the inventor designed an automatic box opener. However, when opening the center seam, it was found that using a conveyor to directly push the cigarettes for cutting resulted in poor cutting stability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a center-slit opening device for opening boxes of slim cigarettes, so as to solve the technical problem of poor cutting stability.

[0004] The technical solution adopted by the present invention is as follows: a center-opening device for opening a box of slim cigarettes, including a left-opening component, a right-opening component, a first-station conveyor and a box-pushing mechanism. The left-opening component and the right-opening component are respectively symmetrically installed on both sides of the central frame component. The first-station conveyor is installed in the middle of the bottom side of the central frame component, and the box-pushing mechanism is installed on the top of the central frame component.

[0005] Furthermore, both the left and right slit assembly include slit blades and pressing wheel sets. The slit blades are two pieces, fixedly connected to the blade holder at the front and rear. The blade holder is telescopically connected to the central connecting rod horizontally and parallelly hinged in the middle of the parallelogram mechanism through a blade telescopic mechanism. The pressing wheel set is rotatably connected to the roller frame. The roller frame is fixedly connected to the top connecting rod hinged at the top of the parallelogram mechanism through a seat plate cantilever and is in the same direction as the slit blades. The side connecting rod of the parallelogram mechanism is hinged to one end of the drive cylinder, and the other end of the drive cylinder is hinged to the central frame assembly.

[0006] Furthermore, the aforementioned blade telescopic mechanism includes a guide mounting plate, a blade guide shaft, and a telescopic cylinder. The blade holder is fixedly connected to the guide mounting plate. Two blade guide shafts are used, with the same end fixedly connected to both sides of the guide mounting plate. The blade guide shafts are connected to the central connecting rod through two linear bearings. The cylinder rod of the telescopic cylinder is fixedly connected to the guide mounting plate, and the cylinder seat of the telescopic cylinder is fixedly connected to the central connecting rod.

[0007] The beneficial effects of the present invention are as follows: Compared with the prior art, the present invention, through the left slit assembly, the right slit assembly, the first station conveyor and the box pushing mechanism, enables the left slit assembly and the right slit assembly to achieve slit cutting between the two sets of ears on the left and right sides of the box body under the action of the conveyor and the box pushing mechanism. The cutting is stable and reliable. Relying solely on the conveyor to push, the existence of cutting resistance will cause the inability to move forward and cut stably. Attached Figure Description

Detailed Implementation

[0009] The present invention will be further described below with reference to specific embodiments.

[0010] Example 1: Refer to Figure 7-18 As shown, a center seam opening device for opening a box of slim cigarettes is provided. The center seam opening device 1 includes a left seam opening component 101, a right seam opening component 102, a first station conveyor 103, and a box pushing mechanism 105. The left seam opening component 101 and the right seam opening component 102 are symmetrically installed on both sides of the central frame component 106. The first station conveyor 103 is installed in the middle of the bottom side of the central frame component 106. The box pushing mechanism 105 is installed on the top of the central frame component 106. The device also includes a first stopper component 104 installed on the first station conveyor 103. The left and right seam opening components cut the center seam tape on the left and right sides of the box as the box pushing mechanism and the first station conveyor move. The first stopper component acts as a limiter, which facilitates the positioning of the left and right seam opening components 101 and 102.

[0011] Among them, reference Figure 12-15Both the left slit assembly 101 and the right slit assembly 102 mentioned above include slit blades 107 and pressing wheel sets 108. Two slit blades 107 are used, fixedly connected front and rear to a blade holder 109. The blade holder 109 has an L-shaped cross-section, with a horizontally inclined groove 127 on its upper surface. The slit blades 107 are placed in the groove 127 and pressed tightly 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 blades 107. The blade pressure plate 128 is fixedly connected to the blade holder 109 with screws. A center slit pressure plate 129 is fixedly connected to the outer end of the blade holder 109, and the center slit pressure plate 129 is provided with slit blades 107. The blade tip of 07 extends out of the strip-shaped through hole 130 on the surface of the center-slit pressure plate 129. The center-slit pressure plate is set to facilitate pressing the tape, ensure smooth cutting during the cutting process, and limit the cutting depth to prevent damage to the internal tape. The center-slit pressure plate 129 has outward-bent parts at both ends to facilitate guidance during the pressing process and prevent jamming of the box body 6. The blade holder 109 is telescopically connected to the middle connecting rod 111, which is horizontally and parallelly hinged in the middle of the parallelogram mechanism 110, through the blade telescopic mechanism. The pressing wheel group 108 is rotatably connected to the roller frame 112. The roller frame 112 is cantilevered and fixedly connected to the top connecting rod 114, which is hinged at the top of the parallelogram mechanism 110, through the seat plate 113 and is kept in contact with the slit blade 107. Holding in the same direction, 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: As 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 is inserted into the tape. Under the push of the box-pushing mechanism, the center seam cutting is completed. With the combined guiding effect of the roller assembly, the two side center seam pressure plates, and the rollers of the first station conveyor, the cutting process is more stable, avoiding the problem of poor cutting quality caused by shaking, resulting in more precise cutting. The parallelogram mechanism works in tandem, achieving pressing while the blade connected in the middle also... The precise vertical center positioning greatly simplifies 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 first parallelogram mechanism. The top two hinge points of the second parallelogram mechanism 131 are hinged to the two side connecting rods of the parallelogram mechanism 110 via a 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, and the pressing of the box is more stable. The height of the second parallelogram mechanism 131 is lower than that of the blade telescopic mechanism to avoid interference during the extension and retraction of the blade telescopic mechanism. The lower ends of the two connecting rods of the parallelogram mechanism are hinged to the portal-shaped main support. The two lower ends of the portal-shaped main support are each 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 two connecting rods of the second parallelogram mechanism 131 are hinged to the auxiliary mounting plate, and the auxiliary mounting plate is fixedly connected to the portal-shaped main bracket.

[0012] 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 facilitate the adjustment range of the blade extension. 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.

[0013] Example 2: Figure 1-65 As shown, a cigarette pack opening device includes a center seam opening device 1, an upper ear opening device 2, a lower ear opening device 3, a flip-up upper and lower ear opening device 4, and a cigarette-clamping 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 flip-up upper and lower ear opening device 4, and the feed end of the cigarette-clamping and pushing device 5 is connected to the discharge end of the flip-up upper and lower ear opening device 4. The center seam opening device 1... The device is used to cut the tape between the upper ear plates 7 and the lower ear plates 8 on both sides of the box body 6 and send the box body 6 out. The upper ear opening device 2 is used to cut the tape between the two ends of the upper ear plates 7 on both sides of the box body to open the upper ear plates and send the box body 6 out. The lower ear opening device 3 is used to cut the tape between the two ends of the lower ear plates 3 on both sides of the box body to open the lower ear plates 3 and send the box body out. The lower ear flipping device 4 is used to flip open the upper ear plates 6 and the lower ear plates 7 on both sides of the box body 6. The cigarette clamping and pushing device 5 is used to clamp the box body 5 and push out the cigarette pack. This invention involves placing the ear-shaped opening device into the center seam opening device, which opens a slit in the tape between the upper and lower ear-shaped opening devices on both sides of the box. Then, the upper ear opening device is pushed in to cut the tape at both ends of the upper ear-shaped opening devices on both sides of the box, thereby loosening the tape on the upper ear-shaped opening devices. The lower ear opening device is then inserted to cut the tape at both ends of the lower ear-shaped opening devices on both sides of the box, thus loosening the lower ear-shaped opening devices. The upper and lower ear-folding devices are then inserted to fold open the upper and lower ear-shaped opening devices. After folding open the upper and lower ear-shaped opening devices, the cigarette packing and pushing devices are inserted to clamp and push out the cigarette pack inside the box, thus completing the opening of the cigarette pack box.

[0014] Among them, reference Figure 7-18As shown, the aforementioned center seam opening device 1 includes a left seam opening component 101, a right seam opening component 102, a first station conveyor 103, and a box pushing mechanism 105. The left seam opening component 101 and the right seam opening component 102 are symmetrically installed on both sides of the central frame component 106. The first station conveyor 103 is installed in the middle of the bottom side of the central frame component 106. The box pushing mechanism 105 is installed on the top of the central frame component 106. It also includes a first parking device component 104 installed on the first station conveyor 103. By the movement of the left seam opening component and the right seam opening component along the box pushing mechanism and the first station conveyor, the center seam tape on the left and right sides of the box is cut. The first parking device component plays a limiting role. After the limiting is completed, it is convenient for the left seam opening component 101 and the right seam opening component 102 to perform movement positioning.

[0015] Among them, reference Figure 12-15The 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 used, fixedly connected to the blade holder 109 front and rear. 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. Convenient and quick, the pressing method provides stable and reliable fixation. The blade is placed at an angle for easy cutting of the center seam tape. The outer end of the blade holder 109 is fixedly connected to the center seam pressure plate 129. The center seam pressure plate 129 is provided with a strip-shaped through hole 130 on the surface of the center seam pressure plate 129, through which the tip of the slit blade 107 extends. The center seam pressure plate facilitates pressing the tape, ensures smooth cutting during the cutting process, and acts as a limit to prevent excessive cutting depth and damage to the internal tape. The two ends of the center seam pressure plate 129 are provided with outward bending parts to facilitate guidance during the pressing process and prevent jamming of the box body 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. The wheel frame 112 is cantilevered and fixedly connected to the top connecting rod 114 hinged to the top of the parallelogram mechanism 110 via the seat plate 113. The roller frame 112 and the slit blade 107 are aligned in the same direction. The roller assembly enables the box to be pressed down while rolling, 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, which in turn drives the roller assembly to press down. When it presses down to the top of the box, the blade extension mechanism extends the blade, and the blade tip is inserted into 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, and the rollers of the first station conveyor are all included. Under the comprehensive guiding effect of the cylinder, 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.

[0016] 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.

[0017] Among them, reference Figure 16 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 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 first station conveyor, the push plate automatically rotates inward during the pushing process. When the box moves to the baffle position of the first 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.

[0018] Reference Figure 17-18As shown, the first station conveyor 103 includes multiple rollers 134, a first conveyor frame 135, and a first conveyor motor 136. The multiple rollers 134 are evenly spaced and rotated on the top of the first conveyor frame 135. Adjacent rollers 134 are connected and driven by a multi-wedge belt 137. One roller 134 is connected to the motor shaft of the first conveyor motor 136 via the multi-wedge belt. The first conveyor motor 136 is installed inside the first conveyor frame 135. Driven by the first conveyor motor 136, all rollers rotate in one direction. Two limiting baffles 138 are symmetrically arranged on both sides of the top of the frame 135. The two limiting baffles 138 are located inside the tip of the slit blade after it is retracted, which provides initial positioning of the box and prevents it from hitting the blade. The two limiting baffles 138 are connected to the side of the first conveyor frame 135 by two L-shaped support plates. The bolt through holes at the connection between the L-shaped support plates and the two limiting baffles 138 are strip holes to facilitate position adjustment. The two ends of the two limiting baffles 138 are symmetrically V-shaped to serve as guides. Each limiting baffle 138 has an integrated connecting plate at the bottom to facilitate installation and improve support rigidity. The first stopper 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 stopper guide rods 141. The two stopper guide rods 141 are connected to a crossbeam 143 via a stopper linear bearing 142. The crossbeam 143 is fixedly connected to the first conveyor frame 135. The cylinder rod of the limiting telescopic cylinder 140 is fixedly connected to the middle of the baffle 139. The two stopper guide rods 141 are arranged on both sides. The cylinder seat of 40 is fixedly connected to the crossbeam 143. Through the action of the limit telescopic cylinder, the baffle is controlled to extend or retract from the roller 134, thereby realizing the parking and opening of the box. The baffle has an L-shaped cross section and good rigidity. The first station conveyor 103, the second station conveyor, the third station conveyor, the fourth station conveyor and the fifth station conveyor have the same structure. The second station conveyor, the third station conveyor, the fourth station conveyor and the fifth station conveyor have the same structure and will not be described again.

[0019] Among them, reference Figure 19-28The aforementioned upper ear opening device 2 includes an upper ear centering and cutting assembly 201, a pressure plate cylinder assembly 202, and a second-station conveyor 203. The upper ear centering and cutting assembly 201 is installed on the upper ear frame assembly 204 and is used to press the lower ears on both sides of the box 6 and cut the tape on both sides of the upper ear. The pressure plate cylinder assembly 202 is installed on 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 and cuts the tape at both ends of the upper ear on both sides. The pressure plate cylinder presses down on the box to prevent shaking or movement. The second-station conveyor 203... 3. The conveyor for transporting the box is the same as the conveyor at the first station. It also includes a second parking device assembly 212, which is the same as the first parking device assembly 104. It is installed on the second station conveyor 203 and extends out of the roller gap of the second station conveyor 203 for a limit. When the box is transported by the second station conveyor, it reaches the second parking device assembly 212 and is limited. The box is pressed by the pressure plate cylinder assembly, and the upper ear centering cutting assembly is controlled to cut the tape at both ends of the upper ear. After the cutting is completed, the pressure plate cylinder assembly is controlled to release the box and retract the limit of the second parking device assembly. Under the power of the conveyor, it enters the next station.

The arc-shaped surface of the slicing blade 205 faces upward. Two sets of arc-shaped slicing blades 205 are used, with each set consisting of two blades arranged opposite each other and capable of moving relative to each other under the drive of the longitudinal and transverse lifting and moving mechanism 206 to simultaneously cut the tape on both sides. Each set of slicing blades 205 is connected to the left and right sides of the upper ear centering frame 228 through the longitudinal and transverse lifting and moving mechanism 206. The telescopic suction cup assembly 207 is installed on the longitudinal and transverse lifting and moving mechanism 206 to adsorb the upper ear. The push plate 208 is installed in front of the slicing blade 205 to press the lower ear and the housing 6 together. The longitudinal and transverse lifting and moving mechanism 206 includes... The assembly includes a lifting component 209, a longitudinal moving component 210, and a lateral moving component 211. Two lifting components 209 are used, each connected to a scriber 205.

The pressure plate cylinder assembly 3 402 has the same structure as the pressure plate cylinder assembly 1 202. It also includes a fourth parking device assembly 427, which has the same structure as the first parking device assembly, is installed on the fourth-station conveyor 403, and extends from the gap between the rollers of the fourth-station conveyor 403. When the box body is conveyed by the fourth station conveyor and reaches the fourth parking device assembly 427, it is stopped. The fourth station conveyor stops, and the box body is pressed down by the pressure plate cylinder assembly three. The flap opening and pressing mechanism 401 is controlled to open and press the upper and lower ears to a V-shape. After the upper and lower ears are opened, the pressure plate cylinder assembly three is controlled to release the box body and retract the limit of the fourth parking device assembly. The fourth station conveyor is started. Under its conveying power, the upper and lower ears remain open and enter the upper and lower ear limiting mechanism of the next station. The upper and lower ear limiting mechanism keeps the upper and lower ears on both sides of the box body in an open state. The flap opening and pressing mechanism 401 includes a push plate 405, a guide plate 406, and a pressing guide plate 407. The push plate 405 is extended and retracted. The lowering mechanism 408 is connected to the flap frame assembly 404. The upper and lower sides of the push plate 405 are each provided with two pairs of guide plates 406 facing the side of 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 ears of the housing. The lower guide plate 407 is fixedly connected to the cylinder rod of the lower guide plate telescopic cylinder 409. The inner end of the lower guide plate 407 has a sloping structure, which better fits the lower ear of the single-sided upper and lower ears that are outwardly V-shaped. 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. The telescopic lifting mechanism 408 includes a push plate horizontal guide rod 411, a lead screw and nut pair 412, an ejection motor 413, a power mounting plate 414, and a push... The vertical guide rod 415 and the vertical cylinder 416 of the push plate are provided. Two horizontal guide rods 411 are used for the push plate. One end of the two horizontal guide rods 411 is fixedly connected to both sides of the push plate 405 and connected to the fixed plate 417 through two linear bearings. The fixed plate 417 is vertically fixedly connected to the bottom of the power mounting plate 414. The other end of the two horizontal guide rods 411 is fixedly connected to the push plate 418. The nut of the lead screw nut pair 412 is fixedly connected to the middle of the push plate 418. The two ends of the lead screw of the lead screw nut pair 412 are respectively rotatably connected to the bearing seat 419 and the middle of the fixed plate 417, and the end extending out of the bearing seat 419 is fixedly connected to the motor shaft of the push motor 413. The lower ends of the two vertical guide rods 415 of the push plate are fixedly connected to the upper surface of the mounting plate 414.Two vertical guide rods 415 are fixedly connected at their upper ends to an arc-shaped tail pull plate 422. The arc-shaped structure facilitates the installation of the vertical cylinder 416 and avoids interference. The two vertical guide rods 415 are connected to both sides of the horizontal plate 420 along its length 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, two support members 423, and two support members 424. The horizontal plate 420 is fixedly connected between the two support members 422. Each support member 422 is in the shape of an angle steel, with a reinforcing rib on one side of its inner corner. On support member 2 423, two support members 2 423 are fixedly connected by a reinforcing crossbeam 426. Support member 2 423 is a vertical beam structure, with both ends fixedly connected to support member 425 and support member 3 424 respectively. Support member 425 is fixedly connected to the top of the flap frame assembly 404. Support member 3 424 is an inverted L-shaped structure, with its lower end fixedly connected to the side crossbeam 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, which in turn drives the push plate to move up and down. Driven by the power telescopic mechanism, the push plate moves telescopically. When the whole device moves up and down and back and forth, the push plate enters the inner side between the upper and lower ears, and the lower ear is limited by the lower guide plate pressed down by the lower side, and the upper ear is limited by the push plate, so that the flaps of the upper and lower ears open.

[0028] Working principle of the top and bottom ear flipping 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 top and bottom ears of the box are cut, they are sent to the top and bottom ear flipping device station. The top and bottom ears on both sides 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 is started to press the box. The body controls the push plate 405 to move 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 moves up, and under the action of the guide plate 406, the upper ear is opened, so that the upper ear is also in an open state, forming an outward V-shape with the lower ear. At this time, the pressure plate cylinder assembly three is released, and the limit of the fourth parking device assembly is retracted. Under the action of the fourth station conveyor, the box with the upper and lower ears in an open state is sent to the next station. The open upper and lower ears are kept in an open state under the limit of the upper and lower ear limit mechanism of the next station.

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 top clamping mechanism 502 and the fifth-station conveyor 503 are respectively installed on the cigarette-pushing frame assembly 505. At the top and bottom center, a top clamping mechanism 502 is used to clamp the front and rear ends of the housing 6 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, is installed on the fifth station conveyor 503, and extends out of the roller gap of the fifth station conveyor 503 for limitation. The upper ear limiting mechanism includes a smoke-pushing inlet guide rod 5. 27 and the smoke-pushing end guide rod 528, the smoke-pushing end guide rod 527 is fixedly connected to the smoke-pushing frame assembly 505 through the inlet push rod bracket 529, and the smoke-pushing end guide rod 528 is fixedly connected to the smoke-pushing frame assembly 505 through the outlet push rod bracket 530. The smoke-pushing end guide rod 527 and the smoke-pushing end guide rod 528 keep the upper ear that was opened in the previous process in an open state. The ends of the smoke-pushing end guide rod 527 and the smoke-pushing end guide rod 528 facing the previous process have an outward V-shaped structure, which plays a guiding role. Under the conveyor of the fifth station, the cigarette pack reaches the fifth parking device assembly 526 and is stopped. 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 cigarette pack out of the box and retracts the limit of the fourth parking device assembly. The fourth station conveyor is started. Under its conveying power, the upper and lower ears remain open and enter the upper and lower ear limiting mechanism of the next station. The upper and lower ear limiting mechanism keeps the upper and lower ears on both sides of the box always open.

[0030] Reference Figures 52-57As shown, the aforementioned smoke-pushing mechanism assembly 501 includes a height-variable pusher head 506, a pusher head cylinder 507, and pusher head guide rods 508. The height-variable pusher head 506 is fixedly connected to one end of four pusher head guide rods 508, and the four pusher head guide rods 508 are arranged at the four corners on both sides. The cylinder rod of the pusher head cylinder 507 is fixedly connected to the middle of the height-variable pusher head 506. The four pusher head guide rods 508 are connected to the support 510 through pusher head linear bearings 509. The cylinder seat of the pusher head cylinder 507 is fixedly connected to the support 510, and the support 510 is fixedly connected to the smoke-pushing support frame. On 511, the pusher cylinder 507 drives the variable pusher to move along the pusher guide rod and the pusher linear bearing, entering the box to push out the cigarette packs inside. The movement is smooth and reliable. The height-variable pusher can push out cigarette packs inside the box at different heights, reducing costs, increasing the contact area, and making the pushing smoother. The height-variable pusher 506 includes a base head 531 and a lifting head 532. The base head 531 has an opening at the top and a comb-shaped groove at the front end. The lifting head 532 has an inverted L-shaped structure, and the front end has comb-shaped strips that intersect and align with the comb-shaped grooves. The comb-shaped strips are inserted into the comb-shaped grooves and fit together, maintaining overlap throughout the lifting process (the maximum lifting amount ensures that overlap is always maintained), improving the rigidity and pushing stability of the cigarette pusher. An inverted L-shaped pusher plate 533 is fixedly connected to the bottom of the lifting head 532. The sidewalls of the pusher plate 533 are fixedly connected to the sliders of the two pusher lifting slider guide rail pairs 534. The middle part of the pusher plate 533 is fixedly connected to the nut of the lifting screw nut pair 535 via a nut seat. The two ends of the lifting screw nut pair 535 are rotatably connected to the bearing seats. The base head 531 extends outwards from one end and is connected to the push head drive motor 537 via a belt drive mechanism 536. The push head drive motor 537 is fixedly installed inside the base head 531. The push head drive motor 537 drives the lead screw and nut pair, which in turn pushes the push plate to move up and down along the lifting slider guide rail pair 534, thereby realizing the adjustable lifting height of the push head. An elastic anti-collision post 538 is installed in the base head 531 directly below the slider of the push head lifting slider guide rail pair 534 to prevent the slider from falling off the guide rail during descent and to play an elastic buffer protection role.

[0031] To ensure a smooth cigarette ejection and avoid interference from the lower earpiece's repositioning, refer to... Figure 52 The lower end pressing limit plate 539 is installed below the cigarette pushing mechanism component 501. The lower end pressing limit plate 539 is fixedly connected to the cylinder rod connecting plate 541 of the lower end limiting directional telescopic cylinder 540. The cylinder seat of the lower end limiting directional telescopic cylinder 540 is fixedly connected to the cigarette pushing support frame 511 through the cylinder seat bracket 542. The lower end pressing limit plate 539 faces the previous process section and opens outward to facilitate the guiding function. It keeps the lower ear that was opened in the previous process continuously entering the current station and keeping it in an open state. The open lower ear avoids the influence during the process of pushing out the cigarette pack and the problem that it is difficult to keep tilting downward by its own weight.

[0032] Reference Figures 58-61 As 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 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.

The transition plate 567 facilitates docking with the fifth station conveyor, thereby feeding the pushed-out cigarette packs onto the buffer belt conveyor 504. The side of the transition plate 567 facing the fifth station conveyor is equipped with an outlet pressing limit plate 568. The outlet pressing limit plate 568 can limit the outlet lower ear of the previous station to prevent the lower ear from returning to its original position and affecting the pushing out of the cigarette packs. The lifting baffle assembly 548 includes a baffle plate 569, a baffle frame 570, a baffle telescopic cylinder 571, and baffle guide rods 572. The upper end of the baffle plate 569 is fixedly connected to the lower ends of two baffle guide rods 572. The two baffle guide rods 572 are connected to the U-shaped baffle frame 570 via linear bearings. The cylinder rod of the baffle telescopic cylinder 571 is fixedly connected to the middle of the upper end of the baffle plate 569, and the cylinder seat of the baffle telescopic cylinder 571 is fixedly connected to the baffle frame 570. Two sliding grooves 573 are embedded on both sides of the baffle plate 569. The two sliding grooves 573 are fixedly connected to the end face of the profile frame 559. The baffle telescopic cylinder 571 drives the baffle plate 569 to move up and down along the sliding grooves, achieving flush blocking of the cigarette packs.
