[0043] Combine the following Figures 1 to 6 Embodiments of the present invention are described.

[0044] This embodiment relates to a buckling structure, comprising: a frame 1, a clamping device and a belt winding device 300;

[0045] The clamping device includes a first clamping mechanism 210 and a second clamping mechanism 220. The first clamping mechanism 210 includes a first clamping slide 211 slidably arranged on the frame 1 along the front-back direction and a first clamping plate 212 rotatably arranged on the first clamping slide 211.

[0046] The second clamping mechanism 220 includes a second clamping slide 221 slidably arranged on the frame 1 along the front-back direction and a second clamping plate 222 rotatably arranged on the second clamping slide 221, the first clamping plate 212 and the second clamping plate 222 are arranged in a front-to-back interval, and a film roll clamping position is formed between the first clamping plate 212 and the second clamping plate 222;

[0047] The tape winding device 300 includes a tape winding slide 310 arranged on the first clamping slide 211, a tape winding roller 320 rotatably arranged on the tape winding slide 310, a tape pressing wheel 330 rotatably arranged on the tape winding slide 310, and a tape breaking knife 340 arranged on the tape winding slide 310. The tape winding slide 310 is driven to move back and forth toward the film roll clamping position, and the tape breaking knife 340 is driven to move back and forth toward the film roll clamping position.

[0048] The first clamping plate 212 and the second clamping plate 222 move laterally to clamp the film roll; the protective tape 11 is pre-placed on the winding roller 320 and the protective tape 11 is led out and placed on the side of the pressure roller 330 pointing to the film roll, the winding slide 310 is driven to move toward the film roll, and the head of the protective tape 11 is adhered to the film roll. Then the first clamping plate 212 and the second clamping plate 222 rotate synchronously to drive the film roll to rotate, so that the adhesive surface of the protective tape 11 is continuously wrapped around the film roll, the tape wrapping is automatically realized, and the corners of the film roll are automatically reinforced.

[0049] Further references Figure 3 to Figure 4 The tape winding device 300 further includes a tape folding mechanism 350, which includes a tape folding driver 351 disposed on the tape winding slide 310, a tape folding plate 352 driven by the tape folding driver 351, and a tape folding wheel 353 rotatably disposed on the tape folding plate 352, the tape folding wheel 353 being located on the side of the tape winding roller 320 facing away from the second clamping plate 222, and the tape folding wheel 353 being used to press the portion of the adhesive tape protruding from the film roll toward the inner side of the film roll. The tape folding wheel 353 is located on the side of the tape winding roller 320 facing away from the second clamping plate 222, and spatially facing the portion of the protective tape 11 protruding from the film roll. The folding mechanism 350 and the folding wheel 353 are used in conjunction with the tape winding roller 320. When the tape winding roller 320 winds the tape, the position is adjusted so that part of the tape is attached to the film roll and the other part protrudes out of the film roll. The folding drive drives the folding wheel 353 to extend and press the protruding part against the side of the film roll, forming an "L"-shaped protective tape 11, which can better protect the corners of the film roll and further enhance the protective performance of the protective tape 11 on the film roll.

[0050] The tape winding device 300 further includes a tape winding guide roller 360, which is arranged on the tape winding slide 310 and is located between the tape cutting knife 340 and the tape winding roller 320. When the protective tape 11 is cut by the tape cutting knife 340, the portion where the head of the protective tape 11 contacts the tape pressing wheel 330 is cut off. If it is necessary to reset the head of the protective tape 11 to the side of the tape pressing wheel 330 facing the film roll clamping position, a common method is to set a power at the tape winding guide roller 360 to extend the head of the protective tape 11 to the tape pressing wheel 330. Although the method of setting power can also be implemented, since the head of the protective tape 11 is relatively soft, the protective tape 11 is prone to deviation during the process of being driven to extend to the tape pressing wheel 330, and manual intervention is required for adjustment, and the operation stability is poor. In addition, the method of setting power also has the problems of high cost and high system complexity.

[0051] In this embodiment, the tape guide roller 360 is configured to improve the problem of poor continuous running stability after the head of the protective tape 11 is cut off. The tape guide roller 360 in this embodiment is located between the tape winding roller 320 and the tape cutting knife 340. When the head of the protective tape 11 extends to the tape pressing wheel 330, it needs to cross the tape guide roller 360, the tape cutting knife 340 and the tape pressing wheel 330 in sequence. After the tape cutting knife 340 cuts the protective tape 11, one end of the head of the protective tape 11 still crosses the tape guide roller 360. When the protective tape 11 needs to be attached to the next film roll, the tape guide roller 360 contacts the film roll, and the head of the protective tape 11 can be pressed onto the film roll, thereby ensuring that the head of the protective tape 11 is reliably bonded to the film roll. Subsequently, by rotating the film roll toward the tape winding roller 320, the protective tape 11 can be continuously wound on the film roll. The tape winding guide pressure roller 360 not only plays the role of pressing the protective tape 11 onto the film roll, but also plays a guiding role. After the tape breaking knife 340 cuts off the tape head of the protective tape 11, it can ensure the correct position of the tape head, cleverly achieving continuous, automatic and stable adhesion of the tape head of the protective tape 11 to the film roll, and no additional power is required. The structure is relatively simple and reliable.

[0052] Furthermore, the tape winding device 300 further includes a tape retreat drive assembly disposed on the tape winding slide 310, and a tape retreat swing block 370 rotatably connected to the tape winding slide 310. The tape retreat swing block 370 is driven by the retreat drive assembly to swing back and forth toward the center of the first clamping plate 212. The tape winding guide roller 360, the tape winding roller 320, the tape pressure wheel 330 and the tape breaking knife 340 are all disposed on the tape retreat swing block 370. The tape retreat swing block 370 is configured, and the retreat drive assembly drives the tape retreat swing block 370 to swing, so that the tape winding roller 320, the tape pressure wheel 330 and the tape breaking knife 340 can quickly leave the surface of the film roll, thereby preventing the tape breaking knife 340 from cutting the protective tape 11 when cutting the film roll. In addition, when the tape winding guide pressure roller 360, the tape winding roller 320, the tape pressure wheel 330 and the tape breaking knife 340 are swung, the tape winding guide pressure roller and the tape pressure wheel 330 cooperate with each other. When the tape winding roller 320 is swung in the direction away from the film roll, the tape winding roller 320, the tape winding guide pressure roller 360 and the tape pressure wheel 330 are disabled and can still form a certain tension on the protective tape 11 so that the tape breaking knife 340 can reliably cut off the protective tape roll. Furthermore, by adopting the swinging form, the tape winding guide pressure roller 360 and the tape pressure wheel 330 can better fit the film rolls of different diameters.

[0053] This embodiment provides two forms of reinforcing the film roll. The first form is: directly wrapping the edge of the film material with tape and then bending the portion of the tape that exceeds the edge of the film roll inward.

[0054] The first reinforcement form is achieved by the tape winding device 300 in this embodiment, and its specific working process is as follows: first, the protective tape 11 is rolled and fixed on the tape winding roller 320, and the head of the protective tape 11 is guided to the tape pressure wheel 330 after passing through the tape winding guide roller 360; then, the film roll is fixed on the film roll clamping position by moving the first clamping slide 211 and the second clamping slide 221; then, the tape pressure wheel 330 is leaned against the film roll to press the adhesive side of the protective tape 11 against the peripheral wall of the film roll, and then the first clamping plate 212 rotates to drive the film roll to rotate so that the protective tape 11 is wrapped around the film roll. After wrapping, the protruding part of the protective tape 11 is bent to the end face of the film roll through the tape folding mechanism 350, so as to form an "L"-shaped protective angle at the corner of the film roll.

[0055] The second form is: two protective side panels 12 are placed at the two end surfaces of the film roll, the protective side panels 12 protrude circumferentially from the film roll, the outer edges of the two protective side panels 12 are bent inward to wrap the film roll to form a folded section, and then the tape is wrapped around the folded section of the protective side panels 12, and the folded part of the protective side panels 12 is wrapped around the rolled film, so that the protective side panels 12 on both sides are fixed to the film roll as a whole, completing the reinforcement and packaging of the film roll.

[0056] When implementing the second form of reinforcement structure, film roll protection side plates 12 are placed on both sides of the film roll and the three are clamped as a whole on the film roll clamping position. The protruding part of the protection side plate 12 is bent by the folding device 400 to form a folded section, and then wrapped with the winding device 300 to obtain the reinforced film roll.

[0057] Further references Figure 5 The buckling structure further includes a folding plate device 400, which is used to fold the portion of the protective side plate 12 protruding from the film roll toward the peripheral wall of the film roll. By configuring the folding plate device 400, the folding of the paperboard can be automatically realized, and the film roll can be conveniently reinforced in the second form in cooperation with the winding device 300.

[0058] Furthermore, the folding plate device 400 includes a folding plate push plate 410 and a guide plate driving mechanism, the first clamping plate 212 is provided with a plurality of folding plate guide grooves 2121, the folding plate guide grooves 2121 extend radially, the number of the folding plate push plates 410 is several, the folding plate push plates 410 slide along the folding plate guide grooves 2121, the guide plate driving mechanism includes a folding plate rotation driver, a folding plate transmission swivel seat 420 and a plurality of folding plate connecting rods 430, the folding plate rotation driver is arranged on the frame 1, the folding plate rotation driver is drivingly connected to the folding plate transmission swivel seat 420, and the two sides of the folding plate connecting rod 430 are respectively hinged to the folding plate transmission swivel seat 420 and the folding plate push plate 410. When the folding plate rotating driver rotates, the folding plate connecting rod 430 is driven to swing through the folding plate transmission device, and each guide plate push plate is dragged to slide along the guide plate slide groove by the folding plate connecting rod 430, thereby driving each folding plate push rod to rotate. With this structure, multiple folding plate connecting rods 430 can be driven to rotate at one time, thereby driving multiple folding plate connecting rods 430 to slide along the guide plate slide groove toward the center of the first clamping plate 212 at one time, and folding the edges at one time to achieve bending, which has the advantages of simple structure and flexible layout. It can be understood that in order to ensure that the protruding part of the protective side plate 12 can be bent inward smoothly, a number of notches are set on the protruding part of the protective side plate 12 to ensure that the various parts do not interfere with each other when bending inward, such as Figure 6 shown.

[0059] Furthermore, the tape winding device 300 further comprises a folding plate pressing wheel 380, and the folding plate pressing wheel 380 is located between the tape pressing wheel 330 and the tape winding roller 320. By configuring the folding plate pressing wheel 380, after each folding plate push plate 410 bends the protruding portion of the protective side plate 12 to form a folded section, the folding plate pressing wheel 380 is further pressed before being wrapped by the tape pressing wheel 330, so as to ensure that the tape pressing wheel 330 can wrap and fix the folded section together when wrapping the protective tape 11.

[0060] Furthermore, the belt winding device 300 also includes a folding plate guide plate 390, which is arranged on the side of the folding plate pressure wheel 380 facing away from the belt pressing wheel 330, and a folding plate guide surface 391 is provided on the folding plate guide plate 390, and the folding plate guide surface 391 is adjacent to the guide end of the folding plate pressure wheel 380 and away from the guide start end of the folding plate pressure wheel 380, and the guide end of the folding plate guide surface 391 is located between the folding plate pressure wheel 380 and the rotation axis of the first clamping plate 212, and the folding plate guide surface 391 tends to the central axis of the first clamping plate 212 in the process of extending from the guide start end to the guide end. In order to prevent the folding section from being reversely pressed when it contacts the folding plate pressure wheel 380, that is, pressed toward the side facing away from the first clamping plate 212 and the film roll, a folding plate guide plate 390 is also configured in this embodiment to protect the folding section of the side plate 12 from contacting the folding plate guide surface 391 of the folding plate pressure wheel 380 during the process of following the film roll rotation. Under the guiding action of the guide surface, the folding section can be pressed toward the side where the film roll is located, and the folding plate pressure wheel 380 can normally re-press the folding section, so that the folding section can be normally wrapped later. Specifically, in the embodiment including the winding belt retreat swing block 370, the folding plate pressure wheel 380 is rotatably arranged on the winding belt retreat swing block 370, and the folding plate guide block is arranged on the winding belt retreat swing block 370, and swings synchronously with the belt pressure wheel 330.

[0061] Furthermore, the invention also includes a roll supporting device 100, which includes a roll supporting block 110 arranged on the frame 1; the roll supporting device 100 also includes a roll supporting lifting driver 120 arranged on the frame 1, the number of the roll supporting lifting drivers 120 is multiple, the number of the roll supporting blocks 110 is multiple, the roll supporting lifting drivers 120 are drivingly connected to the roll supporting blocks 110, and the roll supporting blocks 110 are arranged side by side. By configuring multiple roll supporting lifting drivers 120 and multiple roll supporting blocks 110, and arranging the above-mentioned roll supporting blocks 110 side by side, the top surfaces of the multiple roll supporting blocks 110 jointly form a roll supporting position, and different numbers of roll supporting blocks 110 can be lifted and lowered as needed, and the size of the roll that can be supported can be conveniently adjusted to the corresponding size of the film roll.

[0062] The present disclosure also provides an embodiment of a packaging line, comprising a buckling structure of any one of the above embodiments.

[0063] Since the packaging line includes a buckling structure of any of the above embodiments, it also has the beneficial effects of any of the above buckling structures.

[0064] In this embodiment, the first clamping mechanism 210 and the second clamping mechanism 220 are symmetrically arranged along the front-to-back direction, and a belt winding device 300 and a folding device 400 are correspondingly arranged on the second clamping slide 221 of the second clamping mechanism 220 to realize packaging on both sides of the film roll.
