A four-station tubular film packaging machine is an automated device used to package products in continuous rolls of film (also known as roll film). It is commonly used in packaging processes in the food, pharmaceutical, cosmetic, and daily necessities industries.

[0003] The existing four-station roll film packaging machine operates as follows: First, the product is placed into the feeding position via a conveyor mechanism. Then, the roll film is stretched and conveyed to the sealing area above the product. Next, the roll film is heat-sealed to form a sealed bag or package. Simultaneously with sealing, the roll film is also cut as needed to ensure each package is intact.

[0004] However, it also has many problems, such as an insufficiently compact structure and a lack of labeling mechanisms and processes. Therefore, there is an urgent need to provide a four-station tubular film packaging machine to solve at least one of the above-mentioned problems. Utility Model Content

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0085] refer to Figure 1-6The embodiments of this application provide a four-station tubular film packaging machine, which includes a turntable 1, a clamping assembly 2, a bag opening assembly 3, a filling assembly 4, and a sealing assembly 5. Turntable 1 is capable of rotating around its own axis; turntable 1 may include a drive motor to drive turntable 1 to rotate; clamping assembly 2 is disposed on turntable 1, clamping assembly 2 is configured to receive and clamp the packaging bag to be filled at the film-applying station and sequentially transfer it through the opening station, filling station, and sealing station, the film-applying station, opening station, filling station, and sealing station array surrounding turntable 1; bag opening assembly 3 includes a first suction cup gripper 31 and a second suction cup gripper 32 disposed on one side of the opening station, the first suction cup gripper 31 and the second suction cup gripper 32 can move closer or further away from each other to grasp the bag opening of the packaging bag located at the opening station and open the bag opening; filling assembly 4 is disposed on one side of the filling station, filling assembly 4 is configured to align with the bag opening of the packaging bag located at the opening station for filling; sealing assembly 5 is disposed on one side of the sealing station, sealing assembly 5 is configured to heat seal the bag opening of the packaging bag located at the sealing station.

[0086] Since the film-attaching station, opening station, filling station, and sealing station are arranged around the turntable 1, and similarly, the bag-opening component 3, filling component 4, and sealing component 5 are arranged around the turntable 1, the overall layout is compact and the space is used efficiently. In addition, by rotating the turntable 1, the clamping component 2 is driven to pass through the film-attaching station, opening station, filling station, and sealing station in sequence, and the bag-opening component 3, filling component 4, and sealing component 5 can be used to automate the opening, filling, and sealing of the packaging bag.

[0087] In some implementations, reference Figure 1-6 There are four sets of clamping components 2. The four sets of clamping components 2 are fixed on the turntable 1 in a circumferential array, so that the synchronous operation of each station can be realized. The opening, bagging and sealing processes of the four packaging bags are carried out synchronously in sequence, thereby improving work efficiency.

[0088] refer to Figure 1-6In some embodiments, the clamping assembly 2 includes a first column 21, a first cantilever 22, a first linear actuator 23, a first gripper actuator 24, a second column 25, a second cantilever 26, a second linear actuator 27, and a second gripper actuator 28; the first column 21 is fixed to the turntable 1; the first cantilever 22 is fixed to the first column 21; the first linear actuator 23 is fixed to the first cantilever 22; the first gripper actuator 24 is fixed to the output end of the first linear actuator 23; the second column 25 is fixed to the turntable 1; the second cantilever 26... The first linear actuator 23 is fixed to the second column 25; the second linear actuator 27 is fixed to the second cantilever 26; the second gripper actuator 28 is fixed to the output end of the second linear actuator 27. The first linear actuator 23 and the second linear actuator 27 are arranged opposite each other at intervals on the horizontal plane. The first linear actuator 23 and the second linear actuator 27 are configured to drive the corresponding first gripper actuator 24 and the second gripper actuator 28 to move away from each other in the horizontal direction to form a clearance space to avoid the packaging bag, or to move closer to each other to grip both sides of the packaging bag. The first linear actuator 23, the first gripper actuator 24, the second linear actuator 27, and the second gripper actuator 28 can adopt existing pneumatic or hydraulic structures, and are not specifically limited. The first column 21 and the first cantilever 22 suspend the first linear actuator 23 and the first gripper actuator 24 in mid-air, while the second column 25 and the second cantilever 26 suspend the second linear actuator 27 and the second gripper actuator 28 in mid-air. This allows them to grip the packaging bag in mid-air, with the bag opening facing upwards and the bottom downwards, placing the bag in a suspended, top-down position. The first column 21 and the second column 25 can be detachably connected to the turntable 1 for easy replacement and adjustment.

[0089] In some implementations, reference Figure 1-6The first suction cup gripper 31 includes a first displacement drive source 311 and a first suction cup 312, with the first suction cup 312 fixed to the output end of the first displacement drive source 311. The second suction cup gripper 32 includes a second displacement drive source 321 and a second suction cup 322, with the second suction cup 322 fixed to the output end of the second displacement drive source 321. The first suction cup 312 and the second suction cup 322 are arranged radially at intervals on the turntable 1 to form an opening station. The first displacement drive source 311 and the second displacement drive source 321 are configured to drive the first suction cup 312 and the second suction cup 322 to reciprocate nearing and faring movements radially on the turntable 1, thereby gripping the opening of the packaging bag located at the opening station and opening the bag. The first suction cup 312 and the second suction cup 322 can use existing structures and are not specifically limited. The first displacement drive source 311 and the second displacement drive source 321 can be linear cylinders. The first suction cup 312 and the second suction cup 322 grip the two opposite sides of the packaging bag like suction cups, then tear open the bag opening. During the tearing process, the two ends of the clamping assembly 2 that grip the packaging bag can move closer together, thus relaxing the packaging bag and facilitating the removal of the bag opening. The two ends of the clamping assembly 2 that grip the packaging bag can be the positions of the first gripper actuator 24 and the second gripper actuator 28, and their distance from each other can be adjusted by the first linear actuator 23 and the second linear actuator 27.

[0090] In some implementations, reference Figure 1-6 The loading assembly 4 includes a lifting drive source 41 and a discharge hopper 42. The discharge hopper 42 is located at the output end of the lifting drive source 41. The discharge hopper 42 is positioned directly above the loading station. The lifting drive source 41 is configured to drive the discharge hopper 42 downwards to insert its bottom outlet into the opening of the packaging bag at the loading station. The lifting drive source 41 is also configured to drive the discharge hopper 42 upwards to avoid the packaging bag at the loading station. The top opening of the discharge hopper 42 facilitates the introduction of material, guiding it from the bottom outlet into the packaging bag. The lifting drive source 41 can adjust the lifting height of the discharge hopper 42, allowing it to lower when needed and rise when not in use to avoid the clamping assembly 2. The structure is simple and easy to operate.

[0091] refer to Figure 1-6In some embodiments, the sealing assembly 5 includes a first linear drive source 51, a first heating head 52, a second linear drive source 53, and a second heating head 54. The first heating head 52 is disposed at the output end of the first linear drive source 51; the second heating head 54 is disposed at the output end of the second linear drive source 53. The first heating head 52 and the second heating head 54 are arranged radially spaced on the turntable 1 to form a sealing station. The first linear drive source 51 and the second linear drive source 53 are configured to drive the first heating head 52 and the second heating head 54 to reciprocate nearing and faring movements radially on the turntable 1 to heat-seal the bag opening of the packaging bag located at the sealing station. The first linear drive source 51 and the second linear drive source 53 employ existing linear cylinders; one of the first heating head 52 and the second heating head 54 has a heating rod, which generates a suitable temperature through electric heating to heat-seal the bag opening of the packaging bag.

[0092] In some implementations, reference Figure 1-6 The four-station tubular film packaging machine also includes an unloading conveyor belt 6, which is positioned directly below the sealing station. The clamping assembly 2 is configured to unload the sealed packaging bags onto the unloading conveyor belt 6. The unloading conveyor belt 6 can automatically transfer the sealed packaging bags out, further improving the overall level of automation.

[0093] In some implementations, reference Figure 1-9 The four-station tubular film packaging machine also includes a feeding mechanism 7, a tensioning and film feeding mechanism 8, a marking mechanism 9, a cutting mechanism 10, and a transfer mechanism 100. The feeding mechanism 7 is used to provide tubular film; the tensioning and film feeding mechanism 8 is located downstream of the feeding mechanism 7 and is used to tension the tubular film stretched from the feeding mechanism 7 and drive the tensioned tubular film to be conveyed; the marking mechanism 9 is located on one side of the tensioning and film feeding mechanism 8 and is used to mark the surface of the tubular film passing through the tensioning and film feeding mechanism 8; the cutting mechanism 10 is located downstream of the tensioning and film feeding mechanism 8 and is used to heat-cut and heat-seal the tubular film passing through the cutting mechanism 10 to obtain a packaging bag with one end open; the transfer mechanism 100 is located downstream of the cutting mechanism 10 and is used to clamp the packaging bag obtained by heat-cutting and heat-sealing and transfer the packaging bag to the film receiving station.

[0094] The marking mechanism 9 can be an existing one, which can be mounted on the frame and located on the path of the film conveyor. The marking part of the marking mechanism 9 faces the side of the passing film, thus marking on the side. The tensioning and feeding mechanism 8 includes multiple tension rollers, with an active driving tension roller 81 and a driven tension roller 82 at the end closest to the cutting mechanism 10. A narrow seal is formed between the active driving tension roller 81 and the driven tension roller 82 for the marked film to pass through. The active driving tension roller 81 and the driven tension roller 82 press the passing film, and the film is fed to the cutting mechanism 10 by the rotation of the active driving tension roller 81. The feeding mechanism 7 may include a rotatable roll on which the film is wound, and the film is stretched and fed by rotation.

[0095] In some implementations, reference Figure 1-9 The cutting mechanism 10 includes a first linear cylinder 101, a first heat-sealing head 102, a second heat-sealing head 103, a second linear cylinder 104, and a cutting blade 105. The first heat-sealing head 102 is disposed at the output end of the first linear cylinder 101. The second heat-sealing head 103 is disposed at an interval opposite to the first heat-sealing head 102, and a vertical channel for the tubular film to pass through is formed between the first heat-sealing head 102 and the second heat-sealing head 103. Along the vertical channel from top to bottom, the first heat-sealing head 102 has an upper end and a lower end, and the upper end has a heating part for heat-sealing the tubular film. The second linear cylinder 104 is disposed at the first heat-sealing head 102. The cutting blade 105 is disposed at the output end of the second linear cylinder 104 and is located between the upper end and the lower end. The cutting blade 105 is used to cut the tubular film.

[0096] The first heat-sealing head 102 has an upper end and a lower end. The upper end has a heating part for heat-sealing the tubular film. The cutting blade 105 is located between the upper end and the lower end. This design of the cutting mechanism 10 can ensure that the heat-sealed edge formed during each cut is located upstream of the cutting line. That is, each cut can cut a packaging bag from the tubular film. The bottom of the packaging bag is the end that is sealed by heat sealing, and the top of the packaging bag is the open end. In this way, the packaging bag can be directly transferred horizontally without turning the packaging bag upside down.

[0097] In some implementations, reference Figure 1-9The transfer mechanism 100 includes a translation component 1001, a first lifter 1002, a first drive gripper 1003, a second lifter 1004, and a second drive gripper 1005.

The second drive gripper 1005 and the first drive gripper 1003 are arranged alternately. The translation component 1001 is configured to drive the first drive gripper 1003 and the second drive gripper 1005 to reciprocate. The device moves between the film exit station and the film receiving station, with the film exit station located downstream of the cutting mechanism 10 and upstream of the film receiving station. The first drive gripper 1003 and the second drive gripper 1005 are configured to rise at the film exit station via the first lifter 1002 and the second lifter 1004 to clamp both sides of the packaging bag at the film exit station. The first drive gripper 1003 and the second drive gripper 1005 are also configured to descend at the film receiving station via the first lifter 1002 and the second lifter 1004 to allow the clamping assembly 2 located at the film receiving station to receive and clamp the packaging bag to be filled.

[0098] refer to Figure 1-9 In some embodiments of this application, the transfer mechanism 100 transfers the packaging bags cut by the cutting mechanism 10 to the film-attaching station, enabling the various mechanisms to achieve more reasonable spatial coordination and collaborative arrangement.

[0099] Among them, reference Figure 1-9 The second drive gripper 1005 and the first drive gripper 1003 can adopt the same structure. Specifically, the second drive gripper 1005 includes a main body, a first finger 10051 and a second finger 10052 connected to the main body. The first finger 10051 is stationary, while the second finger 10052 reciprocates at a 90° angle relative to the main body. The second finger 10052 can rotate back and forth and stop at a clamping position and a releasing position. In the clamping position, the second finger 10052 and the first finger 10051 clamp the packaging bag side by side.
