[0002] Film winding machines, as a powerful assistant in the modern packaging industry, with their efficient and precise packaging performance, escort the transportation safety of various products. Through an automated control system, they evenly stretch and tightly wind the film around the goods, not only enhancing the stability of the packaging but also improving the packaging efficiency and reducing labor costs.

[0003] In the Chinese patent with the application number CN202322428745.5, a film winding machine is disclosed, which includes a chassis, a load-carrying disk rotatably connected to the chassis, a driving motor installed on the chassis, and a winding assembly. A turntable is rotatably arranged on the chassis and rotates around the outer periphery of the load-carrying disk. The winding assembly is arranged on the turntable and located on the outer periphery of the load-carrying disk. A linkage assembly for driving the turntable and the load-carrying disk to rotate coaxially in opposite directions is connected between the driving motor and the load-carrying disk and the turntable, having the following advantages and effects: the winding working efficiency of the film winding machine is higher, the service life is long, and the operation is convenient, etc.

[0004] In the above patent during operation, although the material is wound with the film, when the film is cut after the winding is completed, usually the tail end of the film is adsorbed on the surface of the previous layer of film by means of static electricity. Due to the limited strength of static electricity adsorption, especially in the case of high humidity or when there is dust, oil stains, etc. on the film surface, the static electricity adsorption effect will be greatly reduced, making the tail end of the film easy to come loose, resulting in a reduction in the stability of the packaging.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0021] Embodiment 1 In order to solve the technical problem of how to improve the stability of film winding, as Figures 1-8 and Figure 10 shown, the following preferred technical solutions are provided A film winding machine for transporting corrugated cardboard, comprising a conveyor 1, a column 2 is arranged on one side of the conveyor 1, a winding machine body 3 is fixedly installed on the lower surface of the column 2, a bracket mechanism 6 for winding the film is arranged on the inner wall of the winding machine body 3, a tray 4 is fixedly installed on the upper surface of the conveyor 1, and a cardboard body 5 is fixedly installed on the upper surface of the tray 4.

[0022] The bracket mechanism 6 includes a housing 61 arranged on the inner wall of the winding machine body 3, a moving plate 62 is movably arranged inside the housing 61, a cutting assembly 63 for cutting the film is movably installed on one side of the moving plate 62, a flattening member 64 for flattening the film is movably arranged on one side of the housing 61, a support plate 65 is movably arranged inside the housing 61, and a film body 651 is arranged inside the support plate 65; The flattening member 64 includes a flattening plate 641 movably arranged on one side of the housing 61, an extrusion assembly 645 for extruding glue is movably arranged inside the flattening plate 641, a downward pressing assembly 642 for driving the extrusion assembly 645 to discharge glue at a fixed point is arranged on one side of the flattening plate 641. After the film winding is completed, the flattening member 64 can flatten the film against the surface of the tray 4, making the film present a right-angled state, and then cutting it through the cutting assembly 63. During the cutting process of the cutting assembly 63, the cutting assembly 63 will contact the downward pressing assembly 642, causing the downward pressing assembly 642 to descend. As the downward pressing assembly 642 descends, the extrusion assembly 645 located inside the flattening plate 641 will move horizontally, thereby spraying the glue onto the inner wall of the tail end of the film, making the tail end of the film fit against the surface of the previous layer of film, and finally making the tail end of the film firmly adhere to the surface of the previous layer of film through the viscosity of the glue, thereby improving the stability of the film.

[0023] A motor A611 is fixedly installed on one side of the housing 61, and a threaded rod A612 is arranged at the output end of the motor A611; A long plate B647 is movably arranged on one side of the flattening plate 641, the long plate B647 is sleeved on the outer surface of the threaded rod A612, a clamping column 6471 is fixedly installed on the upper surface of the long plate B647, and a limiting plate 649 is fixedly installed on one side of the flattening plate 641. By starting the motor A611, the threaded rod A612 drives the long plate B647 to move, and the limiting plate 649 drives the film to move horizontally. Since the film passes through the gap between the flattening plate 641 and the limiting plate 649, when the limiting plate 649 moves, the film will adhere to the inner wall of the limiting plate 649. Moreover, since one end of the limiting plate 649 is close to the outer surface of the tray 4, the film can be flattened and then cut through the cutting assembly 63 to prevent the tail end of the film from moving randomly during cutting.

[0024] The lower surface of the moving plate 62 is provided with an inclined groove 621. The upper surface of the moving plate 62 is fixedly installed with a motor B 622. The output end of the motor B 622 is provided with a threaded rod B 623. The bottom of the moving plate 62 is fixedly installed with a long plate A 624. The surface of the long plate A 624 is provided with a reciprocating groove 625. The inclined groove 621 is slidably connected with the clamping column 6471. Through the cooperation of the clamping column 6471 and the inclined groove 621, when the smoothing member 64 smooths the thin film, it can drive the moving plate 62 to move, so that the cutting assembly 63 can fit onto the outer surface of the cardboard body 5, preparing for subsequent cutting.

[0025] The cutting assembly 63 includes a rectangular plate 631 movably arranged on one side of the moving plate 62. A knife groove 632 and a hole groove 633 are formed inside the rectangular plate 631. The knife groove 632 is communicated with the hole groove 633. A through groove is formed on the surface of the rectangular plate 631, and the through groove is adapted to the long plate A 624. A cutting knife 635 is movably arranged inside the knife groove 632. A guide rod 636 is fixedly installed on one side of the cutting knife 635. The guide rod 636 is adapted to the reciprocating groove 625. A spring plate 634 is arranged on one side of the rectangular plate 631. Through the connection of the guide rod 636 and the reciprocating groove 625, then by starting the motor B 622, the threaded rod B 623 drives the cutting assembly 63 to descend. At this time, the descending cutting knife 635 will perform reciprocating cutting due to the cooperation of the guide rod 636 and the reciprocating groove 625, thereby improving the efficiency of thin film cutting.

[0026] A glue cavity 6411 is formed inside the smoothing plate 641, and a block groove 6419 is also formed inside the smoothing plate 641; The extrusion assembly 645 includes a trapezoidal block 6451 movably arranged inside the smoothing plate 641. The trapezoidal block 6451 is slidably connected inside the block groove 6419. A push rod 6452 and a spring D 6459 are fixedly installed on one side of the trapezoidal block 6451. The spring D 6459 is located below the push rod 6452. One end of the spring D 6459 is fixedly connected to the glue cavity 6411. A push plate 6453 is fixedly installed on one side of the push rod 6452. The push plate 6453 is movably connected inside the glue cavity 6411. A T-shaped groove 6454 is formed on the lower surface of the trapezoidal block 6451. A T-shaped block 6455 is movably arranged inside the T-shaped groove 6454. A magnet B 6456 is fixedly installed on one side of the T-shaped block 6455. Through the cooperation of the trapezoidal block 6451, when the pressing-down assembly 642 descends, it can drive the trapezoidal block 6451 to move, so that the push rod 6452 drives the push plate 6453 to move, thereby extruding the glue inside the glue cavity 6411 and spraying it onto the surface of the front-layer thin film through the pipeline. Subsequently, when the pressing-down assembly 642 passes through a set of extrusion assemblies 645, the spring D 6459 will drive the trapezoidal block 6451 to reset, waiting for the next spot spraying of glue.

[0027] A bottom plate 6457 is fixedly installed on the lower surface of the T-shaped block 6455. A groove 6458 is formed on the surface of the bottom plate 6457. A rack 646 is sleeved on the outer surface of the bottom plate 6457; A magnetic block B6461 is fixedly installed on the lower surface of the rack 646. A rectangular groove 6462 is formed on one side of the rack 646. The rectangular groove 6462 is adapted to the bottom plate 6457. A short plate 6463 is movably arranged inside the rectangular groove 6462. A spring C6464 is fixedly installed on one side of the short plate 6463. One end of the spring C6464 is fixedly connected to the inner wall of the groove 6458. The groove 6458 is adapted to the short plate 6463. Through the cooperation of the spring C6464, the short plate 6463 and the groove 6458, when the ladder block 6451 resets, it can drive the coating assembly 643 to work, so as to prepare for improving the bonding strength between the glue and the film subsequently.

[0028] The pressing-down assembly 642 includes a lower pressing plate 6421 movably arranged on one side of the flattening plate 641. There are two groups of the lower pressing plates 6421. One group of the lower pressing plates 6421 is fixedly connected to one side of the flattening plate 641, and the other group of the lower pressing plates 6421 is movably connected to the flattening plate 641. A fixing rod 6425 is arranged between the two groups of the lower pressing plates 6421. The fixing rod 6425 is fixedly connected to one group of the lower pressing plates 6421 and movably connected to the other group of the lower pressing plates 6421. A short rod 6422 is fixedly installed on one side of one group of the lower pressing plates 6421. A sliding plate 6423 is fixedly installed on one side of the short rod 6422. A cylinder is fixedly installed at one end of the sliding plate 6423. A slope 6424 is arranged on one side of the sliding plate 6423. The slope 6424 is attached to one side of the ladder block 6451. A spring A6426 is fixedly installed between the two groups of the lower pressing plates 6421. The lower pressing plate 6421 and the threaded rod B623 are on the same horizontal line. Through the movable lower pressing plate 6421 and the threaded rod B623, when the threaded rod B623 descends, the threaded rod B623 will drive one group of the lower pressing plates 6421 to descend, so that the sliding plate 6423 will descend together. The descending sliding plate 6423 will squeeze the ladder block 6451, so that the ladder block 6451 will squeeze out the glue inside the glue cavity 6411. When the cutting assembly 63 resets, the movable lower pressing plate 6421 will be reset due to the reset of the spring A6426.

[0029] Communication holes 6412 and plate grooves 6413 are formed inside the flattening plate 641. There are two groups of the plate grooves 6413. The two groups of the plate grooves 6413 are located on both sides of the sliding plate 6423. The plate grooves 6413 are communicated with the communication holes 6412. A magnetic steel A is fixedly installed on the inner wall of one group of the plate grooves 6413; The isolation component 644 includes a linkage plate 6441 movably arranged inside the flattening plate 641. A dial plate 6442 is fixedly installed on the upper surface of the linkage plate 6441. An isolation plate 6443 is fixedly installed on one side of the linkage plate 6441. A magnet B is fixedly installed at one end of the isolation plate 6443. The isolation plate 6443 is slidably arranged inside the plate groove 6413. A spring B 6444 is fixedly installed on the inner wall of one group of plate grooves 6413. A baffle 6445 is fixedly installed at one end of the spring B 6444. Both the baffle 6445 and the isolation plate 6443 are adapted to the plate groove 6413. The isolation plate 6443 and the baffle 6445 are arranged in a mirror image. By sliding the linkage plate 6441, the isolation plate 6443 is located inside the left plate groove 6413. At this time, multiple communication holes 6412 are communicated. Subsequently, glue is added into the communication holes 6412 through a pipeline. At this time, the baffle 6445 ejected by the spring B 6444 can prevent the infiltration of glue. After the glue fills each glue cavity 6411 through the communication holes 6412, the linkage plate 6441 is slid again to make the isolation plate 6443 move into the right communication hole 6412, thereby squeezing the spring B 6444 to make the magnet A and the magnet B attract each other, so as to fix the isolation plate 6443 inside the communication hole 6412 and prevent the upper glue from flowing to the lower layer, resulting in a reduction in the glue output of the upper glue.

[0030] Specifically, when the film winding of the cardboard body 5 is completed, start the motor A611 to make the threaded rod A612 drive the flattening plate 641 to move. As the flattening plate 641 moves, the clamping posts 6471 located on the surface of the long plate B647 will move along the moving plate 62. Since the film is located between the flattening plate 641 and the limiting plate 649, when the flattening plate 641 moves, the film can not only be flattened by the limiting plate 649 to further fit the surface of the previous layer of film, but also drive the moving plate 62 to extend, so that the cutting assembly 63 moves to the film cutting point. At this time, the film will form a right angle with the cardboard body 5 along the inner wall of the limiting plate 649. At this time, one side of the extended cutting assembly 63 will fit the cardboard body 5. Then start the motor B622 to make the motor B622 drive the cutting assembly 63 to descend. At this time, the guide rod 636 inside the rectangular plate 631 will reciprocate along the reciprocating groove 625, so as to cut the film. As the cutting assembly 63 extends, the spring plate 634 that has been in a compressed state will reset, so that during the descending process, it will drive the lower pressing plate 6421 to descend together. Since one side of the sliding plate 6423 is in contact with one side of the ladder block 6451, when the sliding plate 6423 descends, the ladder block 6451 will be pushed, so that the ladder block 6451 drives the push rod 6452 and the push plate 6453 to move, and the push plate 6453 squeezes out the glue inside the glue cavity 6411, and the glue is squeezed onto the surface of the previous layer of film. Since there are three sets of extrusion assemblies 645 and the three sets of extrusion assemblies 645 are not connected, when the sliding plate 6423 passes the first set of extrusion assemblies 645 and reaches the second set of extrusion assemblies 645, the first set of extrusion assemblies 645 will be reset by the spring D6459, so as to drive the push plate 6453 to reset. At this time, the glue will be sprayed onto the surface of the previous layer of film in a dot spray manner. Finally, after the film cutting is completed, the tail end of the film will contact the glue on the surface of the previous layer of film, so as to fix the tail end of the film, thus improving the stability of the film packaging.

[0031] Embodiment 2 To solve the technical problem of how to further improve the stability of the film, such as Figures 7-9 and Figure 11As shown in the figure, the following preferred technical solutions are provided: An application component 643 for evenly applying glue is fixedly installed inside the screed board 641. The application component 643 includes a rotating column fixedly installed inside the screed board 641. A gear 6431 is sleeved on the outer surface of the rotating column. A short column 6432 is fixedly installed on one side of the gear 6431. A receiving rod 6433 is movably sleeved on the outer surface of the short column 6432. A support rod 6434 is movably arranged inside the receiving rod 6433. One end of the support rod 6434 is provided with a roller 6435. The outer surface of the roller 6435 is attached to the end of the film. The gear 6431 meshes with a rack 646. By the movement of the rack 646, the rotation of the gear 6431 can be driven. The rotating gear 6431 will drive the receiving rod 6433 to perform a circular motion, thereby driving the roller 6435 to perform a lifting motion, so that the roller 6435 evenly applies the sprayed glue, thereby increasing the contact area between the glue and the surface of the front film layer.

[0032] A vertical groove 648 is also provided inside the screed board 641. The sliding plate 6423 is located inside the vertical groove 648. An annular groove 6414 is formed on the inner wall of the vertical groove 648. The annular groove 6414 is adapted to the cylinder at one end of the sliding plate 6423. A sliding groove 6416, a magnet A 6415 and a return groove 6417 are formed on the inner wall of the screed board 641. The magnet A 6415 is fixedly installed on the inner wall of the sliding groove 6416. The magnet A 6415 attracts the magnet B 6456. A magnetic block A 6418 is fixedly installed on the inner wall of the return groove 6417. The magnetic block A 6418 repels the magnetic block B 6461. The return groove 6417 is slidably connected to the magnetic block B 6461. The sliding groove 6416 is slidably connected to the T block 6455. By the magnetic attraction between the magnet A 6415 and the magnet B 6456, when the ladder block 6451 moves to one end of the block groove 6419, the T block 6455 can still move a certain distance, thereby increasing the rotation angle of the gear 6431 and further increasing the lifting distance of the roller 6435. Then, by the magnetic repulsion between the magnetic block A 6418 and the magnetic block B 6461, when the magnetic block B 6461 comes to the left side of the return groove 6417 along the return groove 6417, the spring C 6464 will eject the rack 646, so that the teeth of the rack 646 mesh with the teeth of the gear 6431, thereby driving the gear 6431 to rotate. When the rack 646 moves to the position of the magnetic block A 6418, due to the magnetic repulsion, the spring C 6464 is compressed, so that the rack 646 disengages from the gear 6431. Finally, when the sliding plate 6423 descends to the lowest point, the cylinder will move along the ring at one end of the annular groove 6414, so that the sliding plate 6423 is misaligned with the ladder block 6451, thereby enabling the sliding plate 6423 to reset.

[0033] Specifically, when the ladder block 6451 moves, the magnetic block B6461 will also move along the meandering groove 6417. When the ladder block 6451 moves to the inner wall of the block groove 6419, at this time, the magnet A6415 and the magnet B6456 will attract each other, driving the T block 6455 to continue moving, so that the T block 6455 moves to the inner wall of the T groove 6454. At this time, the ladder block 6451 will reach the leftmost end of the meandering groove 6417, and then the spring C6464 will reset, causing the magnetic block B6461 to move a certain distance again at the leftmost end along the meandering groove 6417. At this time, the rack 646 will mesh with the gear 6431. Subsequently, when the ladder block 6451 resets, the meshed rack 646 will drive the gear 6431 to rotate counterclockwise, so that the storage rod 6433 drives the roller 6435 to reciprocate up and down, thereby evenly applying the glue sprayed out point by point. Finally, the magnetic block B6461 will move to the magnetic block A6418. Under the repulsive magnetic action of the magnetic block A6418, the rack 646 moves a certain distance again to wrap the bottom plate 6457. Thus, through the reciprocating up and down of the roller 6435, the glue can be evenly applied, increasing the area of the film tail end in contact with the glue, thereby further improving the stability of the film.
