Description

Technical Field

[0001] This invention relates to the field of carton overhead conveying machinery technology, specifically to a carton air cushion packing machine and its usage method. Background Technology

[0002] With the continuous improvement of cigarette packaging machine technology, Ke Zhaohui et al. designed an air cushion packing machine using aerodynamic principles and applied it to the YF611A carton storage and conveying system. This effectively improved the carton conveying efficiency and solved the problem that the packing machine speed could not meet the needs of high-speed cigarette packing.

[0003] However, during the operation of the air cushion packing machine, when the airtight valve below the transparent air duct opens to release the cigarette packs stored in the transparent air duct, the rotating cigarette-dispensing mechanism next to the overhead conveyor belt cannot stop, and the cigarette packs continue to be dispensed into the transparent air duct. At this time, the airtight valve at the bottom of the transparent air duct is in the open state, and the cigarette packs fall freely due to gravity, causing the cigarette packs that continue to be dispensed into the transparent air duct to fall too fast and collide with the cigarette packs below at high speed, resulting in quality defects such as deformation of the cigarette packs or packs.

[0004] Meanwhile, after prolonged use of the air cushion packing machine, dust adheres to the surface of the packing boxes due to static electricity during the conveying process. When the packing boxes pass through the acrylic glass channel wall, they generate relative friction with the dust. After long-term operation, the inner surface of the acrylic glass channel wall will become blurry and rough. The transparent BOPP film wrapped around the packing boxes and PMMA acrylic glass are both plastics, which do not dissipate heat easily, causing the same resin-bonded scratches to appear on the surface of the packing boxes. Summary of the Invention

[0005] The purpose of this invention is to provide a carton air cushion type packing machine and its usage method. When the airtight valve is open, the air vent sealing component closes the exhaust ports of the lower smoke channel and the stacking buffer channel, thereby reducing sudden gas loss when the airtight valve is open. Simultaneously, an ion air replenishment component supplies negative ion high-pressure air to the transparent air duct, isolating the descending smoke cartons and slowing their descent speed to reduce quality defects such as carton deformation. During the repetitive packing and releasing process of the packing machine, negative ion high-pressure air is repeatedly used to eliminate static electricity and dust in the transparent air duct, preventing scratches on the carton surface. Furthermore, before the airtight valve is fully closed, the ion air replenishment component supplies airflow to the transparent air duct, allowing the transparent air duct to quickly return to normal stacking buffer operation.

[0006] Specifically, this invention proposes a carton air cushion type packing machine, including M vertically arranged transparent air channels, an inclined sliding channel connected to a smoke-blocking device at the upper part of the transparent air channels, an airtight valve at the lower part of the transparent air channels, and a sliding soft rubber sheet. The transparent air channel is a cylindrical body with a rectangular cross-section, composed of two wide sides made of stainless steel and two narrow sides made of plexiglass. The upper part of the transparent air channel is a lower smoke channel, and the wide side of the lower smoke channel is provided with a first exhaust hole. The lower part of the transparent air channel is a stacking buffer channel, and the side wall of the stacking buffer channel is provided with a second exhaust hole. The distance between the first exhaust hole and the second exhaust hole gradually decreases, and the hole diameter gradually decreases. The transparent air channel also includes an air hole sealing component and an ion wind replenishment component. The air hole sealing component is located at the upper and lower ends of the wide side and is used for intermittently and automatically sealing and releasing the first exhaust hole and the second exhaust hole. The ion wind replenishment component is fixedly located on the narrow side of the stacking buffer channel and is used to intermittently replenish negative ion wind into the transparent air channel when the airtight valve of the transparent air channel is opened and closed.

[0007] In a preferred embodiment of the present invention, the narrow face of the stacked cache channel is provided with multiple high-pressure ion nozzles at equal intervals, and at least two single-layer high-pressure ion nozzles are arranged side by side on each narrow face.

[0008] In a preferred embodiment of the present invention, the jetting direction of the high-pressure ion nozzle forms an angle of 30°-50° with the inner wall surface of the narrow face.

[0009] In a preferred embodiment of the present invention, the above-mentioned ion wind supplementation component includes an ion wind generator and an air supply duct network. The ion wind generator is fixedly mounted on the frame of the transverse conveyor belt. The air inlet and outlet of the air supply duct network are respectively connected to the ion wind output end of the ion wind generator and the high-pressure ion nozzle.

[0010] In a preferred embodiment of the present invention, the above-mentioned air supply network includes: a 1-to-N pipe, a 1-to-M pipe, and a second 1-to-M pipe. The main pipe of the 1-to-N pipe is connected to the air outlet of the air compressor, and N first branch pipes extend to the corresponding height of the high-pressure ion nozzles on each layer. Each of the N first branch pipes on the 1-to-N pipe is equipped with a first solenoid valve. The main pipe of the 1-to-M pipe is connected to a first branch pipe on the corresponding layer, and M second branch pipes are sequentially connected to two high-pressure ion nozzles corresponding to the narrow face of a single stacked buffer channel. The main pipe of the second 1-to-M pipe is connected to the output end of the ion wind generator, and the tail of the branch pipe of the second 1-to-M pipe is equipped with a flat-mouth air outlet. The flat-mouth air outlet is installed on the upper part of the inclined sliding channel of the smoke-blocking device and the transparent air duct. The high-pressure exhaust air output by the flat-mouth air outlet forms an air curtain, and the air curtain contacts the upper surface of the strip box during the sliding process.

[0011] In a preferred embodiment of the present invention, the ion wind generator includes a high-voltage negative ion output unit, a controller, a PWM output unit, an air compressor control unit, and an air compressor connected in sequence.

[0012] In a preferred embodiment of the present invention, an airtight valve is provided at the tail end of the transparent airway. The airtight valve includes: a rotating shaft, a baffle, an electric telescopic component, and a clamping component. The rotating shaft is fixedly disposed at the lower part of the wide surface. The baffle is rotatably connected to the rotating shaft. An airtight gasket matching the size of the transparent airway is disposed on the upper surface of the baffle. An airbag gasket is disposed on the inner ring of the airtight gasket. A linear groove is disposed on the side of the baffle. A slider is assembled in the groove. The electric telescopic component is fixedly disposed at the tail end of the transparent airway and located in the middle of the narrow surface. The retractable part of the electric telescopic component is connected to the slider. The clamping component is disposed at the lower part of the wide surface on the opposite side of the rotating shaft.

[0013] In a preferred embodiment of the present invention, the airtight valve further includes an airtight sensor, which is disposed at the center of the airbag, and the height of the airtight sensor is less than the minimum height to which the airbag is compressed.

[0014] A method of using a carton air cushion packing machine, comprising any of the carton air cushion packing machines described above, wherein the method of use includes: When the transparent air passage's bar stack buffer is complete and the airtight valve below opens, the air vent sealing assembly is simultaneously activated to block the first and second exhaust vents. When all the buffer cartridges are discharged and the airtight valve is closed, the ion wind replenishment component is simultaneously activated to inject intermittent, short bursts of high-pressure negative ion wind into the stack buffer channel until the airtight valve is completely closed.

[0015] In a preferred embodiment of the present invention, when the airtight valve is completely closed, the ion air replenishment component switches to injecting flat high-pressure exhaust air into the inclined sliding channel of the push smoke device and the transparent air duct to form a blocking air curtain, and the surface dust is removed by high-pressure exhaust air during the downward movement of the smoke strip.

[0016] The present invention achieves the following technical effects compared to the prior art: 1. When the airtight valve is opened, the sealing component is activated simultaneously to close the exhaust vents at the lower smoke passage and the stack buffer passage, thereby reducing the rate of gas loss in the transparent air passage and preventing the bar box in the lower smoke passage from falling too quickly. 2. When the airtight channel is closed, the ion air replenishment component is activated at the same time to intermittently replenish the transparent air channel with short bursts of high-pressure negative ion air, so that the bottom sides of the cigarette pack falling from the upper smoke channel are supported by high-pressure negative ion air at the same time, which can further reduce the descent speed of the pack until the airtight channel is closed and the normal packing operation is started. 3. The ion air replenishment component replenishes high-pressure negative ion air into the transparent air duct, removing static electricity and dust generated inside the transparent air duct, thus preventing scratches on the surface of the carton.

[0026] Please see Figure 1-6 This embodiment provides a carton air cushion type packing machine, which includes M vertically arranged transparent air channels 1, a high-altitude conveying channel 2 set at the top of the transparent air channels 1, and a transverse conveyor belt 3 set at the bottom of the transparent air channels 1. The carton 001 is turned from transverse to longitudinal by the push-blocking smoke device 4 of the packing machine in the high-altitude conveying channel 2, and the carton 001 naturally enters the vertical transparent air channel 1. The transparent air channel 1 and the transverse conveyor belt 3 are connected by an arc-shaped sliding soft rubber sheet 5, which makes the carton 001 descend vertically from the high-altitude conveying channel 2 onto the transverse conveyor belt 3 at a slower speed.

[0027] After prolonged use of the air cushion packing machine, dust adheres to the surface of carton 001 due to static electricity during the conveying process. When carton 001 passes through the acrylic channel wall, it generates relative friction with the dust. After long-term operation, the inner surface of the acrylic channel wall becomes blurry and rough. The transparent BOPP film wrapped around carton 001 is a plastic, just like PMMA acrylic glass, which does not dissipate heat easily, causing the same resin-bonded scratches to appear on the surface of carton 001.

[0028] In this embodiment, the transparent airway 1 is composed of two wide stainless steel sides 110 and two narrow acrylic glass sides 120, forming a rectangular cylindrical body. Its clear dimensions are similar to the external dimensions of the upright cigarette pack, and are 1 to 3 millimeters larger on each side than the projected dimensions of the cigarette pack when it falls vertically. The length of the transparent airway 1 is 2.5-4.5 meters.

[0029] In this embodiment, the wide surface 110 of the transparent air duct 1 is replaced with stainless steel, which prevents welding scratches from forming on the wide surface 110 of the carton 001 after long-term use. Furthermore, the narrow surface 120 of the transparent air duct 1 is made of acrylic glass, ensuring visibility. Additionally, the narrow surface 120 of the carton 001 is a folded surface with thicker transparent paper, providing better abrasion resistance, thus significantly reducing scratches on the carton 001 after it has passed through the packing machine.

[0030] Please see Figure 2The upper part of the transparent air passage 1 is the lower smoke passage 130, and the wide surface 110 of the lower smoke passage 130 is provided with a first exhaust hole 131; the lower part of the transparent air passage 1 is the stacking buffer passage 140, and the wide surface 110 of the stacking buffer passage 140 is also provided with a second exhaust hole 141. The center distance between adjacent exhaust holes on the same side wall is equal to the height of the cigarette when it falls vertically. A proximity switch 150 is provided between the stacking buffer passage 140 and the lower smoke passage 130. When the number of cigarette boxes 001 in the stacking buffer passage 140 meets the release conditions, the airtight valve 160 at the bottom is opened to remove the cigarette boxes 001 in the stacking buffer passage 140.

[0031] When the cigarette pack is pushed into the transparent air passage by the rotating cigarette-dispensing mechanism next to the overhead conveyor belt, the airtight valve 160 at the bottom of the transparent air passage is sealed. The cigarette pack falls due to gravity, forcing the air in the lower air chamber to be squeezed along the four periphery of the cigarette pack and discharged through the symmetrical exhaust holes on both sides.

[0032] In this embodiment, the discharge speed of the sealing gas is controlled by controlling the size and number of vent holes, thereby controlling the descent speed of the strip box 001 to meet different production speed requirements. Specifically, in this embodiment, the number of the first vent hole 131 to the second vent hole 141 gradually decreases, and the hole diameter also gradually decreases, thereby reducing the flow rate of gas overflow and slowing down the descent speed of the strip box 001, which can buffer the strip box 001 during the normal packing process.

[0033] The stack buffer channel 140 is used to control that there is always a strip box 001 at the bottom to form a seal for the transparent air passage 1. When multiple strip boxes 001 are stored in the transparent air passage 1, a rapid release is performed to release the strip boxes 001 stored at the bottom of the channel to the belt conveyor. The number of strip boxes 001 stored in the stack buffer channel 140 can be set according to the actual situation.

[0034] When the airtight valve 160 at the bottom of the transparent air passage 1 opens to release the cigarette pack 001, the rotating cigarette-dispensing mechanism next to the overhead conveyor belt continues to dispense the cigarette packs into the transparent air passage. The cigarette packs fall freely due to gravity, causing them to fall too fast and collide with the cigarette packs below at high speed, resulting in quality defects such as deformation of the cigarette packs or packs.

[0035] The transparent airway 1 in this embodiment also includes an air hole sealing component 170 and an ion wind replenishment component 180. The air hole sealing component 170 is disposed at the upper and lower ends of the wide surface 110 and is used to intermittently and automatically seal and release the first exhaust port 131 and the second exhaust port 141 during the packing process. The ion wind replenishment component 180 is fixedly disposed on the narrow surface 120 of the stack buffer channel 140 and is used to intermittently and automatically replenish ion wind into the transparent airway 1 during the opening and closing of the airtight valve 160.

[0036] The vent sealing assembly 170 can take many forms, and as long as it can intermittently and automatically seal and release the first vent 131 and the second vent 141, it belongs to the same concept of the present invention.

[0037] This embodiment provides a feasible and preferred solution, wherein the pore sealing assembly 170 includes: a metal strip 171, a guide post 172, a first adsorption plate 173, and a second adsorption plate 174. Please refer to [link to relevant documentation]. Figure 4 .

[0038] A metal strip 171, which can be an iron strip, is provided on the stainless steel wide surface 110. The metal strip 171 is provided on both sides of the first exhaust hole 131 / second exhaust hole 141, and the metal strip 171 is an embedded design, which embeds the metal strip 171 in the stainless steel wide surface 110 to prevent the adsorption plate from generating tiny gaps during the sealing process.

[0039] Guide posts 172 are provided at the upper and lower ends of the metal strip 171 of the stainless steel wide surface 110. Springs 178 are sleeved on the guide posts 172, and welding nuts 175 are provided at the ends of the guide posts 172. The first adsorption plate 173 and the second adsorption plate 174 have the same structure and are located on the lower smoke channel 130 and the stack buffer channel 140, respectively. An electromagnet 176 is provided inside the adsorption plate. The position of the electromagnet 176 matches the position of the metal strip 171, and the adsorption range of the electromagnet 176 is larger than the area of ​​the metal strip 171. A silicone pad layer 177 for sealing the exhaust hole is provided on the inner side of the adsorption plate, and smooth through grooves matching the size and position of the guide posts 172 are provided on both sides of the adsorption plate.

[0040] Furthermore, in order to ensure the airflow effect during normal stacking, the first adsorption plate 173 and the second adsorption plate 174 are provided with large-area perforations or densely packed holes in non-blocked positions.

[0041] The assembly and usage of the vent sealing assembly 170 are as follows: A spring 178 is fitted onto the guide post 172; the inner side of the adsorption plate is aligned with the stainless steel wide surface 110; the four smooth through slots of the adsorption plate are assembled onto the guide post 172; nuts are fitted to the ends of the guide post 172 and welded in place; and the adsorption plate is powered on to complete the assembly. When it is necessary to seal the vent, the adsorption plate is powered on. The power supply and solenoid valve control process are controlled by the chip inside the adsorption plate. The electromagnet 176 attracts the metal strip 171, and the adsorption plate compresses the spring 178, pressing the silicone pad 177 on the adsorption plate against the vent, thus sealing the vent. When it is necessary to release the vent, the adsorption plate is de-powered, the electromagnet 176 and the metal strip 171 lose their attraction, the spring 178 resets, and the adsorption plate is pushed out, thus releasing the vent. Therefore, when the airtight valve 160 is opened, the air hole sealing component 170 quickly seals the first exhaust hole 131 and the second exhaust hole 141, which can reduce the large amount of gas loss inside the transparent air passage 1 to a certain extent, thereby reducing the speed at which the cigarette strips continuously fall down the lower smoke passage 130.

[0042] When the first exhaust port 131 and the second exhaust port 141 are closed, a large amount of gas is still lost inside, and the bar box 001 will still fall at a relatively fast speed. For this reason, this embodiment also provides an ion wind supplement component 180, which includes multiple high-pressure ion nozzles 121 evenly spaced on the narrow surface 120 of the stack buffer channel 140. The high-pressure ion nozzles 121 are conventional high-pressure gas nozzles to spray high-pressure columnar gas.

[0043] Please see Figure 3 High-pressure ion nozzles 121 are evenly spaced, and at least two high-pressure ion nozzles 121 are provided on the same layer. At least four jets of high-pressure gas are sprayed from both sides at the same time to decelerate the strip box 001 at multiple height positions.

[0044] The high-pressure ion nozzle 121 is angled at 30°-50° to the inner wall of the narrow surface 120, so that the ejected high-pressure columnar gas can be sprayed to the bottom two ends of the strip box 001, rather than the middle of the strip box 001. Each layer is provided with at least 4 high-pressure ion nozzles 121, which respectively support the four sides of the bottom of the strip box 001, while also facilitating the airflow to overflow upwards from all sides of the strip box 001, preventing the strip box 001 from tipping over, and at the same time carrying away static electricity and dust attached to the transparent air passage 1.

[0045] The ion wind supplementation component 180 includes an ion wind generator 181 and an air supply duct network. The ion wind generator is mounted on the frame of the transverse conveyor belt 3. The air inlet and outlet of the air supply duct network are respectively connected to the ion wind output end of the ion wind generator 181 and the high-pressure ion nozzle 121. Multiple solenoid valves for controlling the air supply effect are installed on the air supply duct network.

[0046] The specific ion wind generator includes a high-pressure negative ion output unit, a controller, a PWM output unit, an air compressor control unit, and an air compressor connected in sequence. The air compressor provides compressed air, and the high-pressure negative ion output unit generates negative ions, which are then output to the air duct network via high-pressure airflow. The controller, PWM output unit, and air compressor control unit control the operating status of the high-pressure negative ion output unit, the air compressor, and the duct network solenoid valves. In this embodiment, the ion wind generator 181 uses high-pressure negative ion air, which serves two purposes: firstly, to reduce the speed of the strip box 001, and secondly, to remove static electricity from the transparent air duct 1, thereby further preventing the transparent air duct 1 from becoming blurred.

[0047] In this embodiment, only one ion wind generator 181 needs to be installed on the entire air cushion type packing machine. The high-pressure negative ion wind is guided to each stack buffer channel 140 through the air supply duct network. For the sake of the equipment's aesthetics, the air supply duct network is introduced from the narrow side 120 at the back of the equipment.

[0048] The air supply duct network includes two types of one-to-many ducts, namely one-to-N duct 182, one-to-M duct 183, and a second one-to-M duct 184.

[0049] The first main pipe of the N-way pipe 182 is connected to the air outlet of the ion wind generator 181, and the N first branch pipes extend to the corresponding height of the high-pressure ion nozzles 121 on each floor. The high-pressure negative oxygen ion wind enters the high-pressure ion nozzles 121 at different heights from the ion wind generator 181 through the N-way pipe 182. Each of the N first branch pipes on the N-way pipe 182 is equipped with a first solenoid valve 185, which is used to intermittently open and close the first solenoid valve 185 according to the different descent speed of the strip box 001 to decelerate the strip box 001 at each height position, so as to ensure that the air outlet speed and time of the high-pressure ion nozzles 121 on each floor are consistent. The main pipe of the M-type pipe 183 is connected to a branch pipe of the corresponding layer. M second branch pipes are sequentially connected to two high-pressure ion nozzles 121 corresponding to the narrow face 120 of a single stacked buffer channel 140. In this embodiment, a single layer of a single stacked buffer channel 140 is provided with 4 high-pressure ion nozzles 121. Therefore, the corresponding second branch pipe is a 1-to-4 pipe. The main pipe of the second branch pipe is led out from the middle of the two wide faces 110. The 4 branch pipes are divided into 2 groups and are respectively connected to the two high-pressure ion nozzles 121 of the same layer of the two narrow faces 120. The pipe distance and pipe diameter of the 4 branch pipes to the first narrow face 120 and the second narrow face 120 are the same.

[0050] When the high-pressure negative oxygen ion air enters the high-pressure ion nozzle 121 at the corresponding height, it is transmitted to the four high-pressure ion nozzles 121 corresponding to the single stack buffer channel 140 through a one-to-M pipe 183. The second branch pipe is a one-to-four pipe to ensure that the air outlet speed and time of the four high-pressure ion nozzles 121 on the same floor are consistent. A second solenoid valve 187 is installed on the main pipe of the one-to-four pipe.

[0051] While the airtight valve 160 is open, the second solenoid valve 187 remains normally open. The first solenoid valve 185 intermittently opens and closes, causing the high-pressure ion nozzles 121 on each floor to simultaneously perform support-release operations, thus achieving a speed reduction effect. When the airtight valve 160 is closed but not completely sealed, the high-pressure ion nozzles 121 continue to eject gas to replenish the lost gas volume inside the transparent air passage 1. The control of each solenoid valve is programmed through a controller and PWM output unit.

[0052] The air supply duct is also equipped with a pressure sensor to detect the air pressure of the air supply duct and a second branch M pipe 184. The main pipe of the second branch M pipe 184 is connected to the output end of the ion air generator 181. The branch pipe of the second branch M pipe 184 is equipped with a push-block smoke device 4 to form an air curtain 002 before the strip box 001 enters the transparent air duct 1, remove dust from the surface of the strip box 001, and prevent dust from entering the transparent air duct 1 to generate static electricity and friction. The pressure sensor and the pressure relief valve are set on the main pipe of the branch N pipe 182.

[0053] The ion wind generator 181 needs to remain open when the bagging machine is turned on. When the airtight valve 160 is opened, the N-pipe 182 and the M-pipe 183 are also opened. However, due to the intermittent opening and closing of the first solenoid valve 185, the internal air pressure of the first solenoid valve 185 increases when it is closed. At this time, the pressure relief valve is used to regulate the air pressure of the pipeline.

[0054] When the airtight valve 160 is fully closed, the main pipe of the N-pipe 182 is closed, and the second solenoid valve 187 is closed. Then the second M-pipe 184 is opened to guide the high-pressure ion air to the position of the push-block smoke device 4.

[0055] Specifically, the second branch M-pipe 184 is equipped with a flat-headed air outlet 186 at its end. This outlet is located above the inclined sliding channel of the smoke-blocking device 4 and the transparent air duct 1. The high-pressure exhaust forms a 30°-45° angle with the transparent air duct 1, creating an air curtain with the flat-headed air outlet 186. Each of the M branch pipes of the second branch M-pipe 184 is equipped with a third solenoid valve. The third solenoid valve ejects flat, high-pressure exhaust air, which serves two purposes: firstly, to remove dust from the surface of the carton 001; and secondly, when the carton 001 enters the inclined sliding channel 003, the flat exhaust provides pressure against the carton 001, preventing it from tilting in the sliding channel.

[0056] In this embodiment, the tail end of the transparent airway 1 is provided with an airtight valve 160. Please refer to [link / reference]. Figure 5 and Figure 6 The airtight valve 160 includes a rotating shaft 161, a baffle 162, an electric telescopic component 163, and a clamping component 164. The rotating shaft 161 is fixedly installed at the lower part of the wide surface 110. The baffle 162 is rotatably connected to the rotating shaft 161. An airtight gasket 165 matching the size of the transparent air passage 1 is provided on the upper surface of the baffle 162. An airbag gasket 166 is provided on the inner ring of the airtight gasket 165. A linear groove 167 is provided on the side of the baffle 162, and a slider 168 is assembled in the groove. The electric telescopic component 163 is fixedly installed at the end of the transparent air passage 1 and located in the middle of the narrow surface 120. The retractable part of the electric telescopic component 163 is hinged to the slider 168. The clamping component 164 is located at the lower part of the wide surface 110 on the opposite side of the rotating shaft 161.

[0057] To further prevent cigarette packs from falling freely due to gravity when the airtight valve 160 is open, causing them to fall too quickly into the transparent air passage 1 and collide with cigarette packs below at high speed, resulting in quality defects such as deformation of the cigarette pack or pack, this embodiment also redesigns the airtight valve 160. The rotating shaft 161 of the airtight valve 160 is equipped with a motor for rotating the shaft 161. When the output shaft of the motor rotates rapidly to close the airtight valve 160, the electric telescopic component 163 quickly retracts, thereby reducing the closing time. Furthermore, the electric telescopic component 163, while retracting, can improve the clamping effect of the airtight gasket 165 and the transparent air passage 1, thereby allowing the transparent air passage 1 to quickly return to the normal stacking state of the pack 001, ensuring the airtightness of the transparent air passage 1. Then, clamping member 164 is used to clamp baffle 162. The inner ring of baffle 162 is provided with air cushion 166 to prevent carton 001 from directly contacting baffle 162 and causing damage to the appearance of carton 001.

[0058] In this embodiment, the airtight valve 160 also includes an airtight sensor 169 for detecting the state of the airtight valve, ensuring that the air chamber forms a sealed space as quickly as possible. The airtight sensor 169 is located at the center of the airbag pad 166, and the height of the airtight sensor 169 is less than the minimum height of the compressed airbag pad 166. The airtight sensor 169 detects the airtightness of the stack buffer channel 140. The airtight sensor 169 is communicatively connected to the controller. When the air pressure value of the airtight sensor 169 decreases, the air vent sealing assembly 170 is controlled to seal the first exhaust port 131 and the second exhaust port 141. When the air pressure value of the airtight sensor 169 recovers, the solenoid valves of the one-way N pipe 182 and the one-way M pipe 183 are closed.

[0059] The method of using the air cushion type packing machine for carton 001 in this embodiment is as follows: When the airtight valve 160 is closed, the push-block smoke device 4 turns the carton 001 from horizontal to vertical and enters the vertical transparent air duct 1 through the inclined sliding channel. At this time, the ion air replenishment component 180 is switched to the inclined sliding channel to form a blocking air curtain. At the same time, the carton 001 removes dust when passing through the blocking air curtain. The carton 001 in the transparent air duct 1 falls under the action of gravity, forcing the air in the lower air chamber to be squeezed along the four peripheries of the cigarette and discharged through the two symmetrical exhaust holes to form an air cushion to help slow down the cigarette while preventing the cigarette from contacting the inner wall of the transparent air duct 1 and causing wear on the appearance of the cigarette. When the number of cigarette packs in the stack buffer channel 140 is sufficient and the proximity switch 150 is triggered, the airtight valve 160 opens. At this time, a large amount of air is lost from the transparent air passage 1, and the air hole sealing component 170 is activated to block the first exhaust hole 131 and the second exhaust hole 141 to reduce the loss of air from the transparent air passage 1. At the same time, the high-pressure ion nozzle 121 in the uppermost row is activated to reduce the speed of the first cigarette pack 001 entering from the lower smoke passage 130. Then, the high-pressure ion nozzles 121 of each layer are activated sequentially from top to bottom. The opening sequence of the high-pressure ion nozzles 121 is obtained by programming the opening time of the solenoid valve. Without delaying the discharge of stacked cigarette packs, the descending cigarette packs are slowed down. The high-pressure ion nozzles 121 intermittently provide short bursts of high-pressure negative ion air to support the bottom of the cigarette pack 001 and slow down the falling speed of the cigarette pack 001 without affecting its descent, until the stacked cigarette pack 001 is discharged and the airtight valve 160 is completely closed. Even when the airtight valve 160 is closed but the seal is not completely completed, high-pressure negative ion air is still injected into the transparent airway 1, which helps the airflow in the transparent airway 1 to recover quickly. While the high-pressure ion nozzle 121 sprays high-pressure negative ion airflow, it can neutralize the static electricity in the transparent air passage 1 and move the dust brought in upward. This allows some of the dust inside the transparent air passage 1 to be discharged with the strip box 001 when the airtight valve 160 is opened, and some of it to be discharged upward through the high-pressure negative ion airflow. When the first exhaust port 131 is opened, it is discharged from the larger diameter first exhaust port 131. This intermittent dust removal and static electricity removal prevents scratches on the appearance of the strip box 001. When the airtight valve 160 is fully closed and the detection value of the airtight sensor 169 reaches the preset value, the high-pressure ion nozzle 121 is closed, and at the same time the air hole sealing component 170 is opened sequentially through the first exhaust hole 131 and the second exhaust hole 141. While discharging some dust and neutralizing airflow from the larger-diameter first exhaust hole 131, the bagging operation is gradually resumed. When the high-pressure ion nozzle 121 is closed, the air supply network switches the air supply point to the inclined sliding channel and injects flat high-pressure exhaust air to form a blocking air curtain. During the descent of the cigarette strip, on the one hand, it prevents the cigarette strip from tilting, and on the other hand, it can remove surface dust through high-pressure exhaust air.

[0060] In this embodiment, the various electronic detection and control components are controlled by a combination of electrical control circuits and PLC programming. The air cushion formed by the vertical channel is always used as a prerequisite for the falling of the packs, thus making up for the logical control loopholes of the air cushion packing machine.

[0061] After the implementation of this technology, no more transparent paper damage to the cigarette packs caused by the excessively fast falling speed of the rigid packs was found, reducing potential quality risks. In addition, the surface scratches of the packs were reduced, achieving excellent transmission performance for the rigid packs. Example 2

[0062] The technical solution of Embodiment 2 is largely the same as that of Embodiment 1, except that the location of the flat-head air outlet 186 of the second M-section pipe is different. Please refer to [link / reference needed]. Figure 7 A baffle can be installed on the wide side of the transparent air duct, and a flat-headed air outlet 186 can be installed on the baffle. The angle of the flat-headed air outlet 186 can be so that it can contact the surface of the falling cigarette.
