[0049] See also Figure 1-Figure 9 The fully automatic spiral packaging machine of the utility model comprises:

[0050] A packaging frame 1, on which a transverse movement mechanism 2 is installed;

[0051] The packaging trolley 3 includes a base 31, on which a mounting frame 32 is rotatably connected via a bearing, and on the mounting frame 32 are mounted a rotating mechanism 33 for driving the packaging paper to rotate, a lifting mechanism 34 for driving the rotating mechanism 33 to carry the packaging paper up and down, a film cutting mechanism 35 for film packaging, and an angle swinging mechanism 36 for driving the mounting frame 32 to swing.

[0052] As a further improvement of the present invention, please refer to Figure 1 The transverse movement mechanism 2 includes slide rails 21 installed on both sides of the packaging frame 1, a transverse movement motor 22 for driving the packaging trolley 3 to move transversely on the slide rails 21, and a transverse movement timing belt 23 for moving the packaging trolley 3. A slider 24 connected to the transverse movement timing belt 23 is installed in the slide rails 21, and the slider 24 is connected to the base 31 of the packaging trolley 3.

[0053] By setting the transverse movement mechanism 2, the packaging trolley 3 can be effectively carried to move horizontally on the packaging frame 1, so that it is convenient to wrap materials of different lengths with wrapping paper of the same width. Compared with the existing parallel packaging using wrapping paper compatible with the wrapped material, the width of the wrapping paper does not need to be changed accordingly according to the width of the paper roll, which has higher practicality.

[0054] As a further improvement of the present invention, please refer to Figure 2 and Figure 3 The lifting mechanism 34 includes a lifting motor 341 and a lifting frame 342. The lifting frame 342 is vertically slidably connected to the inner wall of the mounting frame 32. The lifting motor 341 is installed on the top of the mounting frame 32 and is connected to the lifting frame 342 through a lifting synchronous belt 343.

[0055] The rotating mechanism 33 includes a driving shaft 331 that passes horizontally through the lifting frame 342, and a rotating motor 332 for driving the driving shaft 331 to rotate. The rotating motor 332 is installed on the lifting frame 342 and moves synchronously with the lifting frame 342. The driving shaft 331 is installed on the lifting frame 342 through a bearing. A roller 333 for carrying packaging paper is installed at one end of the driving shaft 331 away from the rotating motor 332.

[0056] When the wrapping paper is mounted on the roller 333, the rotating motor 332 in the rotating mechanism 33 is started, so that the driving shaft 331 can rotate with the wrapping paper through the roller 333, so that the wrapping paper can enter the laminating and cutting mechanism 35 in an orderly manner; and the setting of the lifting mechanism 34, through the starting of the lifting motor 341, can carry the lifting frame 342 to move up and down inside the mounting frame 32 through the lifting synchronous belt 343. The up and down movement of the lifting frame 342 can make the rotating mechanism 33 and the wrapping paper move up and down, thereby changing the distance between the roller 333 and the packaging frame 1, so as to adapt to wrapping paper rolls of different diameters.

[0057] As a further improvement of the present invention, please refer to Figure 4-Figure 7 The laminating and cutting mechanism 35 includes a paper feeding frame 351 fixedly connected to the mounting frame 32, and a conveying unit 352 for driving the packaging paper, a guiding unit 353 for guiding the packaging paper, and a cutting unit 354 for cutting the packaging paper are sequentially installed on the paper feeding frame 351;

[0058] The conveying unit 352 includes a paper feeding roller 3521 and a driven roller 3522. The driven roller 3522 is installed below the paper feeding roller 3521 for carrying the packaging paper. A channel for the packaging paper to pass through is provided between the driven roller 3522 and the paper feeding roller 3521.

[0059] The guide unit 353 is arranged on the paper outlet side of the paper feeding roller 3521, and is used to guide the packaging paper into the cutting unit 354 for cutting, and at the same time limit the end of the packaging paper after cutting. The guide unit 353 includes a supporting plate 3531 on the same tangent line as the driven roller 3522, and a limiting plate 3532 is horizontally arranged directly above the supporting plate 3531. The limiting plate 3532 and the side of the supporting plate 3531 close to the channel are bent outward to form a guide part 3533 for facilitating the packaging paper to enter the supporting plate 3531 and the limit.

[0060] The cutting unit 354 includes a cutting roller 3541 and a fixed knife component 3543 . A cutting knife 3542 is mounted on the cutting roller 3541 . The cutting knife 3542 is obliquely mounted on the cutting roller 3541 .

[0061] The fixed knife component 3543 includes a fixed knife frame 35431 and a fixed knife block 35432 . The fixed knife frame 35431 is installed inside the paper feeder frame 351 via an adjusting screw 35435 for adjusting the height.

[0062] A first screw 35433 and a second screw 35434 are respectively provided at the bottom and the paper feeding side of the fixed knife block 35432. A movable hole for the first screw 35433 to move left and right is opened on the fixed knife frame 35431. The first screw 35433 is mounted on the fixed knife frame 35431 through a nut.

[0063] The second screw rod 35434 on the fixed blade block 35432 is mounted on the paper feed side of the fixed blade holder 35431 through a nut.

[0064] One end of the support plate 3531 away from the guide portion 3533 is bent downward to form a mounting portion 3531a. The mounting portion 3531a of the support plate 3531 is in contact with the paper feed side of the fixed blade block 35432, and a mounting hole for the second screw rod 35434 to penetrate is provided on the mounting portion 3531a.

[0065] A tensioning assembly 355 is also installed on the paper feeding side of the paper feeder frame 351. The tensioning assembly 355 includes a driving cylinder 3551, a rotating shaft 3552 and a tensioning roller 3553. The driving cylinder 3551 is connected to the rotating shaft 3552 through a swing arm 3554, and the two ends of the rotating shaft 3552 are fixedly connected to the two ends of the tensioning roller 3553 through a connecting rod 3555.

[0066] The wrapping paper that has passed through the laminating and cutting mechanism 35 is pulled around the tensioning assembly 355 by the rotation of the material and enters between the paper feeding roller 3521 and the driven roller 3522, and then enters the guide unit 353. Since the guide portion 3533 in the guide unit 353 is bent outward, it is convenient for the wrapping paper to enter between the carrying support plate 3531 and the limiting plate 3532. Since the fixed knife block 35432 is flush with the carrying support plate 3531, the wrapping paper will move toward the paper outlet side of the paper feeding frame 351 after passing through the fixed knife block 35432.

[0067] When the wrapping paper has wrapped the material, the cutting roller 3541 rotates under the drive of the corresponding motor. Since the cutting knife 3542 on the cutting roller 3541 is arranged obliquely, that is, the cutting knife 3542 simulates the action of scissors cutting paper, the wrapping paper can be cut from one end to the other. The whole cutting process is fast and reliable, and the packaging process can be carried out without stopping.

[0068] The swing angle mechanism 36 includes a rotating shaft 365 vertically arranged on the base 31, and the rotating shaft 365 is connected to the arc frame 362 through the mounting frame 32 to be swung; the arc frame 362 is suspended on the base 31, and the center of the arc frame 362 is located on the axis of the rotating shaft 365, and the outer edge of the arc frame 362 coincides with the rotation path of the arc frame 362. A driving component 363 for driving the arc frame 362 to rotate around the rotating shaft 365 as the axis is also installed on the base 31;

[0069] A support frame 361 vertically parallel to the rotating shaft 365 is further provided on the base 31 , and the top of the support frame 361 is connected to the top of the rotating shaft 365 via a connecting piece.

[0070] The driving component 363 includes a driving wheel 3633 and a driven wheel 3634, between which a swing angle synchronous belt 3632 connected to the arc frame 362 is wound, and the driving wheel 3633 is driven by a driving motor 3631;

[0071] The axes of the driving wheel 3633 and the driven wheel 3634 are located on a line parallel to the chord of the arc frame 362;

[0072] The length of the side of the swing angle synchronous belt 3632 close to the arc frame 362 is greater than the side away from the arc frame 362 , and the side of the swing angle synchronous belt 3632 close to the arc frame 362 is bent by the arc frame 362 into an arc shape that matches the arc frame 362 .

[0073] At least two limiting ears 368 for limiting the rotation angle of the rotating shaft 365 are installed on the base 31 , and the two limiting ears 368 are respectively installed on the swing path of the mounting frame 32 or the arc frame 362 .

[0074] Two proximity switches 364 for controlling the driving component 363 to start or stop the driving motor 3631 are also installed on the base 31 . The two proximity switches 364 are installed outside the end point and the starting point of the rotation path of the arc frame 362 .

[0075] The driving motor 3631 in the driving component 363 is started. In this embodiment, the driving motor 3631 is started to rotate the swing angle synchronous belt 3632 through the driving wheel 3633. Since the swing angle synchronous belt 3632 is connected to the arc frame 362, it can effectively ensure that the arc frame 362 can rotate with the rotating shaft 365 as the axis. When the arc frame 362 carries the mounting frame 32 and rotates to contact with a limit ear 368, it will be sensed by a proximity switch 364, thereby effectively controlling the closing of the driving motor 3631. However, when the arc frame 362 carries the mounting frame 32 and contacts with another limit ear 368, the arc frame 362 will approach another proximity switch 364, thereby resetting it. Among them, since the driving point of the swing angle mechanism 36 is connected to the arc frame 362, it is convenient to finely adjust the swing angle, that is, to facilitate fine swing of the device at a small angle. At the same time, since the connection between the rotating shaft 365 and the arc frame 362 is connected through the mounting frame 32, it can effectively save installation space and make the device layout more reasonable.

[0076] When using this utility model:

[0077] By starting the driving motor 3631 in the driving component 363 of the swing angle mechanism 36, the driving wheel 3633 can carry the swing angle synchronous belt 3632 to rotate. Since the swing angle synchronous belt 3632 is connected to the arc frame 362, it can effectively ensure that the arc frame 362 can rotate around the rotating shaft 365 as the axis. When the arc frame 362 carries the mounting frame 32 to rotate to contact with a limit ear 368, it will be sensed by a proximity switch 364, thereby effectively controlling the closing of the driving motor 3631. However, when the arc frame 362 carries the mounting frame 32 to contact with another limit ear 368, the arc frame 362 will approach another proximity switch 364, thereby resetting it.

[0078] First, the lifting motor 341 in the lifting mechanism 34 needs to be started, so that the lifting synchronous belt 343 carries the lifting frame 342 to move up and down inside the mounting frame 32. The up and down movement of the lifting frame 342 can make the rotating mechanism 33 and the packaging paper move up and down, thereby changing the distance between the roller 333 and the packaging frame 1, so as to adapt to packaging paper rolls with different diameters;

[0079] Then, the packaging paper is transferred to the roller 333 of the rotating mechanism 33, and the rotating motor 332 in the rotating mechanism 33 is started, so that the driving shaft 331 can rotate with the packaging paper through the roller 333, so that the packaging paper enters the film-covering and cutting mechanism 35 in an orderly manner;

[0080] The wrapping paper that has passed through the laminating and cutting mechanism 35 is pulled around the tensioning assembly 355 by the rotation of the material and enters between the paper feeding roller 3521 and the driven roller 3522, and then enters the guide unit 353. Since the guide portion 3533 in the guide unit 353 is bent outward, it is convenient for the wrapping paper to enter between the carrying support plate 3531 and the limiting plate 3532. Since the fixed knife block 35432 is flush with the carrying support plate 3531, the wrapping paper will move toward the paper outlet side of the paper feeding frame 351 after passing through the fixed knife block 35432.

[0081] After the wrapping paper passes through the film-coating cutting mechanism 35 and contacts and connects with the material, since the material is rotating all the time, in order to prevent the wrapping paper from being entangled at the same place of the material, the transverse movement mechanism 2 needs to be started. The transverse movement motor 22 in the transverse movement mechanism 2 can be started to carry the packaging trolley 3 to move horizontally through the transverse movement synchronous belt 23 and the slider 24, so that the wrapping paper can be spirally wound on the material, so that the wrapping paper can wrap materials of different diameters. In the process of spiral wrapping, the angle adjustment of the packaging trolley 3 by the swing angle mechanism 36 can adapt to different spiral angles, so it is recommended to adapt to the wrapping of different materials in one step;

[0082] When the wrapping paper has wrapped the material, the cutting roller 3541 rotates under the drive of the corresponding motor. Since the cutting knife 3542 on the cutting roller 3541 is arranged obliquely, that is, the cutting knife 3542 simulates the action of scissors cutting paper, the wrapping paper can be cut from one end to the other. The whole cutting process is fast and reliable, and the packaging process can be carried out without stopping.
