[0072] Specifically, the film storage device 32 is fixed to the bottom of the film feeding mounting frame 31, and the film storage device 32 includes a film storage roller 326, on which the rolled plastic film to be transported is sleeved; the film storage station 321 is formed on the film storage roller 326; a protective partition is also provided on the side of the film storage device 32 close to the bagging roller component 20.

[0073] The film opening device 33 is provided between the film storage device 32 and the film guiding device 34. The film opening device 33 includes a film opening spacer 331. The film opening spacer 331 is used to be placed in the plastic film to separate the inner layer of the plastic film.

[0074] The film guiding device 34 includes a film guiding drive 341, a conveying guide roller 342, a film pressing assembly 343 and a film guiding plate 344; the film guiding drive 341 is a servo motor, and the film guiding drive 341 has an output shaft, and the output shaft of the film guiding drive 341 is connected to the conveying guide roller 342 through a synchronous wheel transmission assembly; the film pressing assembly 343 is arranged on one side of the conveying guide roller 342, and the film pressing assembly 343 is used to press the plastic film against the surface of the conveying guide roller 342, and the film guiding plate 344 is arranged on one side of the conveying guide roller 342 in the film discharging direction; the film guiding drive 341 drives the conveying guide roller 342 to rotate so that the plastic film is delivered to the film discharging station 345 through the film guiding plate 344.

[0075] During use, the rolled plastic film is placed on the film storage roller 326, and the film opening rod 331 is placed inside the plastic film. The film opening rod 331 blocks the inner wall of the plastic film, separating the layers of the plastic film that are tightly attached together. After being layered by the film opening rod 331, the plastic film is wrapped around the conveying guide roller 342. The film pressing assembly 343 provides pressure to press the plastic film against the surface of the conveying guide roller 342, increasing the friction between the plastic film and the surface of the conveying guide roller 342. The film guide drive 341 is activated, and the power provided by the film guide drive 341 drives the conveying guide roller 342 to rotate, sending the plastic film through the film guide plate 344 to the film discharge station 345, thereby ensuring that the plastic film layers can be independently and smoothly conveyed to the subsequent processing stage without interruption. By pre-layering the plastic film during the film feeding process, the subsequent bag opening efficiency of the bagging machine is greatly improved, thereby improving the bagging success rate of the bagging machine.

[0076] Specifically, the film storage device 32 of this embodiment further includes a film feeding drive 322 , a film feeding active roller 323 , a film feeding support roller 324 and a film storage support frame 325 ;

[0077] Both ends of the film storage roller 326 are connected to the top of the film storage support frame 325 through sliding bearing seats, so that the film storage roller 326 can rotate relative to the film storage support frame 325, and the film storage roller 326 can move in the vertical direction relative to the film storage support frame 325.

[0078] The active film feeding roller 323 and the film feeding support roller 324 are respectively arranged on the opposite sides of the bottom of the film storage support frame 325; so that the film storage roller 326 is located above the active film feeding roller 323 and the film feeding support roller 324 in the direction of gravity. During the operation of the equipment, as the plastic film on the film storage roller 326 is consumed, the film storage roller 326 can slide downward under the action of its own mass and gravity, so that the surface of the plastic film at the bottom of the film storage roller 326 can always be in contact with the top of the active film feeding roller 323 and the film feeding support roller 324.

[0079] The film feeding drive 322 is a servo motor, which has an output shaft. The output shaft of the film feeding drive 322 is connected to the film feeding active roller 323 through a synchronous belt drive assembly; the film feeding drive 322 provides power to drive the film feeding active roller 323 to rotate and feed the plastic film into the film opening device 33.

[0080] The film-opening spacer rod 331 of this embodiment is a slender cylindrical rod, and the number of the film-opening spacer rod 331 is 2;

[0081] The film-opening device 33 also includes a first limiting assembly 332 and a second limiting assembly 333. The first limiting assembly 332 and the second limiting assembly 333 are respectively arranged on opposite sides of the film-opening spacer 331, and are used to limit the film-opening spacer 331 between the first limiting assembly 332 and the second limiting assembly 333. The first limiting assembly 332 is arranged below the second limiting assembly 333 in the direction of gravity; the plastic film delivered by the film storage device 32 passes through the first limiting assembly 332 and the second limiting assembly 333 from bottom to top, and the film-opening spacer 331 is wrapped by the plastic film between the first limiting assembly 332 and the second limiting assembly 333. Under the action of gravity, it always stays close to the second limiting assembly 333 below, effectively preventing deviation.

[0082] Specifically, the first limiting assembly 332 includes a first limiting fixed roller and a first limiting movable roller. The first limiting fixed roller and the first limiting movable roller are arranged in parallel. A first limiting gap is formed between the first limiting fixed roller and the first limiting movable roller. The first limiting gap allows the plastic film to pass through. The maximum width of the first limiting gap is smaller than the diameter of the film-opening spacer 331 to prevent the film-opening spacer 331 from escaping from the first limiting gap. The second limiting assembly 333 includes a second limiting fixed roller and a second limiting movable roller. The second limiting fixed roller and the second limiting movable roller are arranged in parallel. A second limiting gap is formed between the second limiting fixed roller and the second limiting movable roller. The second limiting gap allows the plastic film to pass through. The maximum width of the second limiting gap is smaller than the diameter of the film-opening spacer 331 to prevent the film-opening spacer 331 from escaping from the first limiting gap. In this way, the film-opening spacer 331 is controlled between the first limiting assembly 332 and the second limiting assembly 333.

[0083] In this embodiment, a plurality of tension guide rollers 35 are provided between the film storage device 32 and the film opening device 33, and a plurality of tension guide rollers 35 are provided between the film opening device 33 and the film guiding device 34. By winding the plastic film around each tension guide roller 35 in sequence, the direction of the plastic film is guided, and at the same time, the wrap angle of the plastic film on the tension guide roller 35 is increased, so that the tension of the plastic film is adjusted to ensure that the plastic film will not be damaged or twisted during the transmission process, thereby maintaining the stability and neatness of the plastic film.

[0084] The film pressing assembly 343 of this embodiment includes a rotating rod 3431 and a pressure rod 3432.

The pressure rod 3432 is provided with a pressure roller 3433, and a plurality of the pressure rollers 3433 are evenly distributed along the axial direction of the pressure rod 3432. The rotating rod 3431 is rotated to drive the pressure rollers 3433 on the pressure rod 3432 toward or away from the conveying guide roller 342. The pressure rollers 3433 can apply pressure to the plastic film under the action of their own weight, pressing it against the surface of the conveying guide roller 342.

[0085] The rotating rod 3431 is provided with a rocker, which drives the rotating rod 3431 to rotate; by swinging the rocker to rotate the rotating rod 3431 counterclockwise, the pressure wheel 3433 can be driven away from the conveying guide roller 342, so as to make a channel between the pressure wheel 3433 and the conveying guide roller 342 for the loading of the plastic film; by swinging the rocker to rotate the rotating rod 3431 clockwise, the pressure wheel 3433 presses the plastic film toward the conveying guide roller 342; by applying pressure by the pressure wheels 3433 arranged at several intervals on the pressure rod 3432, the layered plastic films can be squeezed and stuck together again.

[0086] Furthermore, an elastic member is provided at the end of the rocker arm, which may be a tension spring. One end of the elastic member is connected to the end of the rocker arm, and the other end of the elastic member is fixed to the film feeding mounting frame 31.

After the plastic film is delivered by the conveying guide roller 342, it enters the film guide channel from the wide end, and is guided and automatically adjusted by the plurality of spring plates spaced apart on both sides, so that the plastic film maintains its flatness, ensuring that the plastic film is delivered to the film discharge station 345 through the film guide plate 344.

[0088] A plastic film length measuring device is also provided near the film discharging station 345. The plastic film length measuring device is a plurality of sensors provided near the film discharging station 345. The device is used to measure the length of the plastic film passing through the film discharging station 345. When the length of the plastic film passing through the film discharging station 345 reaches a preset length, the sensor sends a signal to the main control system to stop the film feeding component 30 from feeding the film.

[0089] The bag sealing and cutting component 40 of this embodiment includes a bag sealing and cutting mounting frame 41 , which provides support and mounting base for various components and mounts the bag sealing and cutting component 40 inside the frame 10 .

[0094] During use, the plastic film is sent to the film discharge station 345 by the film feeding component 30. When the length of the plastic film passing through the film discharge station 345 reaches a preset length, the plastic film stops being transported; the opening and closing driving component 423 of the opening and closing device 42 provides power to drive the first support seat 421 and the second support seat 422 to approach each other, clamping the plastic film between the first clamping surface and the second clamping surface; the knife disc driving component 441 of the bag cutting device 44 drives the rotating knife disc 442 to rotate, cutting the plastic film fixed in the film passing channel, and the sealing device 43 seals the plastic film in the film passing channel, thereby realizing continuous cutting and sealing of the plastic film. Compared with the existing fixed blade, the setting of the rotating knife disc 442 has the characteristics of good cutting effect, which can ensure that the incision is neat and there is no pulling, thereby ensuring the sealing and integrity of the bag.

[0095] Specifically, an upper pressure plate 4211 and a lower pressure plate 4212 are provided on the first clamping surface of this embodiment, and an upper buffer bar 4221 and a lower buffer bar 4222 are provided at the corresponding positions of the second clamping surface, so that the upper buffer bar 4221 and the lower buffer bar 4222 are respectively arranged opposite to the upper pressure plate 4211 and the lower pressure plate 4212; the upper buffer bar 4221 and the lower buffer bar 4222 have the characteristic of elastic deformation under force; when the first support seat 421 and the second support seat 422 approach each other, the upper buffer bar 4221 and the lower buffer bar 4222 respectively abut against the upper pressure plate 4211 and the lower pressure plate 4212, thereby clamping the plastic film in the film passing channel, providing a more stable and reliable clamping effect for the plastic film.

[0096] The sealing device 43 of this embodiment includes a hot knife 431, a heating element, and a stop plate 433. The hot knife 431 is disposed between the upper pressing plate 4211 and the lower pressing plate 4212, and the stop plate 433 is disposed between the upper buffer bar 4221 and the lower buffer bar 4222.

The plastic film cutting area is clamped on both sides between the upper pressure plate 4211 and the upper buffer strip 4221, and the lower pressure plate 4212 and the lower buffer strip 4222, respectively. This prevents displacement during the cutting process, ensuring a smooth and complete cut of the plastic film. A rodless cylinder acts as a driving element, driving the rotating cutter disc 442 back and forth along the length of the second support base 422 to perform the cutting. This provides the rotating cutter disc 442 with efficient, space-saving, and reliable linear power, further improving the bag cutting device 44's effectiveness in cutting the plastic film.

The bag assembly 64 is adjusted in the horizontal direction to align the box plates on opposite sides of the carton with the gap between the first inner bag support structure 631 and the first outer bag support structure 632 of the first bag support assembly 63, and the gap between the second inner bag support structure 641 and the second outer bag support structure 642 of the second bag support assembly 64. The first outer bag support structure 632 and the second outer bag support structure 642 fold the mouth of the plastic bag on the outside of the upper edge of the carton during the process of descending. The first inner bag support structure 631 and the second inner bag support structure 641 are lowered. During the process, the bag slides along the inner wall of the carton, pressing the inner plastic film of the plastic bag to the inner wall of the carton. Then, the opening device 62 drives the first bag-stretching component 63 and the second bag-stretching component 64 to aggregate, so that the plastic bag changes from a tightened state to a relaxed state. Finally, the lifting device 61 drives the opening device 62 and the bag-stretching device to rise, thus completing the entire bagging action. This ensures that the mouth of the plastic bag is stably supported at the mouth of the carton, and the inner plastic film of the plastic bag fits perfectly with the wall of the carton, and the bag mouth of the plastic bag is not easy to fall off during the subsequent material filling process.

[0116] Specifically, the first inner support bag structure 631 includes an inner support plate 6311, and the inner support plate 6311 has a vertically arranged upright portion and a horizontally arranged horizontal portion, and the upright portion and the horizontal portion respectively smooth and fit the inner plastic film of the plastic bag on the side wall and the bottom wall of the carton; the surface of the inner support plate 6311 is evenly distributed with a number of hollow holes, and the air pressure on both sides of the inner support plate 6311 is connected through the hollow holes to avoid the formation of air pressure difference to generate air flow stirring and cause the plastic film to shift; the edges of the inner support plate 6311 are formed with transition fillets, and the transition fillets prevent the inner support plate 6311 from damaging and pulling the plastic film during the contact with the plastic bag.

[0117] Furthermore, the first inner support bag structure 631 of this embodiment also includes an inner support connecting frame 6312 and an inner support driving member 6313. The top end of the inner support connecting frame 6312 is fixed to the bottom of the first opening plate 622, and the inner support connecting frame 6312 is slidably connected to the inner support plate 6311, so that the inner support plate 6311 can be translated in the height direction relative to the inner support connecting frame 6312; specifically, circular flange linear bearings are fixed at both ends of the bottom of the inner support connecting frame 6312, and a guide column is connected in the circular flange linear bearing, and the guide column is vertically arranged, and the bottom end of the guide column is connected to the horizontal part of the inner support plate 6311; so that the inner support connecting frame 6312 is slidably connected to the inner support plate 6311, and the inner support plate 6311 can be translated in the height direction relative to the inner support connecting frame 6312. The inner support driving member 6313 has a fixed end and a telescopic end. The fixed end of the inner support driving member 6313 is fixed to the inner support connecting frame 6312, and the telescopic end of the inner support driving member 6313 is connected to the inner support plate 6311. When the first inner support bag structure 631 enters the carton, the inner support driving member 6313 provides power to drive the inner support plate 6311 to move back and forth in the height direction of the inner support connecting frame 6312, causing the inner support plate 6311 to slide along the inner wall of the carton, further increasing the contact area between the inner support plate 6311 and the carton. At the same time, the back and forth movement can squeeze out the air between the plastic bag and the carton, thereby improving the fit of the plastic bag to the inner wall of the carton.

[0118] The first outer support bag structure 632 of this embodiment includes a first outer support plate 6321 and a second outer support plate 6322. The first outer support plate 6321 is connected to one end of the first opening plate 622 through a first adjusting block 6323, and the second outer support plate 6322 is connected to the other end of the first opening plate 622 through a second adjusting block 6324. The first outer support plate 6321 and the second outer support plate 6322 are arranged opposite to each other; the positions of the first outer support plate 6321 and the second outer support plate 6322 correspond to two adjacent folding corners of the carton, and inner folding corners are formed on the inner sides of the first outer support plate 6321 and the second outer support plate 6322, and the inner folding corners are adapted to the outer edges of the carton; the opening of the plastic bag is folded and pushed along the vertical edges of the carton through the first outer support plate 6321 and the second outer support plate 6322, thereby improving the fit between the opening of the plastic bag and the opening of the carton and the bagging efficiency. Both ends of the first opening plate 622 are provided with long grooves along their length, each of which is threaded with a screw. One end of the screw is connected to the first adjustment block 6323 or the second adjustment block 6324, thereby allowing the first adjustment block 6323 or the second adjustment block 6324 to slide with the first opening plate 622. By loosening the screw, the first adjustment block 6323 or the second adjustment block 6324 slides relative to the first opening plate 622. Tightening the screw locks the relative position of the first adjustment block 6323 or the second adjustment block 6324 with the first opening plate 622, thereby adjusting the relative position of the first outer support plate 6321 and the second outer support plate 6322 to adapt to the bagging requirements of cartons of different sizes. The edges of the first outer support plate 6321 and the second outer support plate 6322 are formed with transition fillets to prevent the first outer support plate 6321 or the second outer support plate 6322 from damaging or pulling the plastic film during contact with the plastic bag.

[0119] The second bag-supporting assembly 64 of this embodiment has the same structure as the first bag-supporting assembly 63 , and the two are arranged relative to each other, which can be understood by those skilled in the art and will not be described in detail here.

[0120] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
