[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] like Figure 1-6 As shown, a packaging printing and reeling anti-wrinkle mechanism includes a printed product 9 and a base frame 1, on which the following are arranged:

[0027] The primary support roller group 31, the secondary support roller group 32 and the winding roller 2 are sequentially arranged to rotate in the horizontal direction;

[0028] The anti-wrinkle component 4 includes a rotating frame 41 rotatably arranged between the secondary support roller group 32 and the winding roller 2, a tensioning wheel 42 is rotatably arranged on the first end of the rotating frame 41, a pressing wheel 43 is rotatably arranged on the second end of the rotating frame 41, and elastic members 44 are arranged at both ends of the rotating frame 41. The rotating frame 41 is driven to rotate by the elastic member 44 so that the tensioning wheel 42 tensions the printed product 9 between the secondary support roller group 32 and the winding roller 2 to be inclined, and the pressing wheel 43 rolls and presses the printed product 9 on the winding roller 2.

[0029] Specifically, Figure 1 As shown, the primary support roller group 31, the secondary support roller group 32 and the winding roller 2 in the base frame 1 are sequentially arranged to rotate in the horizontal direction, and the rotating frame 41 is rotatably arranged between the secondary support roller group 32 and the winding roller 2, as shown in FIG. Figure 2 As shown, the left end of the rotating frame 41 is the first end, and the right end is the second end. The left end of the rotating frame 41 is rotatably provided with a tensioning wheel 42, and the right end is rotatably provided with a pressure wheel 43, and an elastic member 44 is provided on the rotating frame 41 to rotate the rotating frame 41, thereby driving the pressure wheel 43 to rotate close to the winding roller 2. Therefore, when the printed product 9 passes through the primary support roller group 31, the secondary support roller group 32 and the rotating frame 41 in sequence and is wound on the winding roller 2, the tensioning wheel 42 is located below the secondary support roller group 32 in the horizontal direction to tension the printed product 9, thereby avoiding the problem that the printed product 9 is damaged due to subsequent winding wrinkles caused by the relaxation of the printed product 9 during the transportation process. Secondly, it can also improve the stability of the transportation of the printed product 9, avoid the problem that the printed product 9 slips and is difficult to be wound and formed, and improve the uniformity of winding; and as shown Figure 2 As shown, the pressure wheel 43 presses the finished printed product 9 on the winding roller 2. As the winding roller 2 rolls, the finished printed product 9 is continuously wound into shape. The pressure wheel 43 contacts the finished printed product 9 and applies downward pressure to flatten the finished printed product 9 to be wound up, thereby further ensuring the flatness of the finished printed product 9 during the winding process, and further avoiding the problem of damage to the pattern thereon due to subsequent winding wrinkles caused by the looseness of the finished printed product 9 during the transportation process.

[0030] Furthermore, the elastic member 44 can be replaced by a spiral spring, a tension spring, an air bag, or other elastic workpieces known to those skilled in the art.

[0031] In the above technical solution, the rotating frame 41 of the anti-wrinkle component 4 is rotated by the elastic member 44, so that the tensioning wheel 42 is located below the horizontal direction of the secondary support roller group 32 to tension the finished printed product 9, and the pressure wheel 43 contacts the finished printed product 9 and applies downward pressure to flatten the finished printed product 9 to be rolled up, thereby further ensuring the flatness of the finished printed product 9 during the rolling process, and avoiding the problem of damage to the pattern thereon due to subsequent rolling wrinkles caused by the looseness of the finished printed product 9 during the transportation process.

[0032] As a further embodiment provided by the present invention, it also includes an air pipe 51 arranged on the rotating frame 41, the pressure wheel 43 is hollow, and a breathable plate 52 is arranged in a circular array on the pressure wheel 43, and the outer periphery of the pressure wheel 43 rolls and presses the printed product 9 on the winding roller 2 so that the breathable plate 52 rotates circumferentially in turn to contact the printed product 9.

[0033] Specifically, Figure 3 As shown, the interior of the pressure wheel 43 is hollow and an air permeable plate 52 is arranged circumferentially thereon, and the air pipe 51 is connected with the interior of the pressure wheel 43. When the pressure wheel 43 presses the finished printed product 9 on the winding roller 2, the pressure wheel 43 follows the rolling to flatten the finished printed product 9 due to the pressure on the finished printed product 9. The pressure wheel 43 rolls to make the air permeable plate 52 rotate in turn and contact the upper side of the finished printed product 9, and the air pipe 51 fills the pressure wheel 43 with clean gas. The clean gas impacts the surface of the finished printed product 9 through the air permeable plate 52, thereby blowing away the dust deposited on the upper side of the finished printed product 9, avoiding the problem of winding wrinkles caused by dust accumulation in the subsequent collection process due to dust deposition on the upper side of the finished printed product 9, further improving the uniformity and stability of the winding, and avoiding the problem of pattern damage during the winding process of the finished printed product 9.

[0034] Furthermore, due to the presence of the air permeable plate 52 , dust that may be carried in the clean gas can be filtered out in the pinch wheel 43 , thereby preventing the problem of dust impacting the printed product 9 at high speed and causing damage to the surface pattern of the printed product 9 .

[0035] The cleaning gas may be clean nitrogen or clean oxygen, and the air pipe 51 is connected to an external air pump, which will not be described in detail here.

[0036] As a further embodiment of the present invention, it also includes a sliding seat 61 symmetrically arranged on the rotating frame 41, a vacuum tube 62 is arranged on the sliding seat 61, and a suction groove 611 connected to the vacuum tube 62 is opened on the sliding seat 61. The rotating frame 41 is driven to rotate so that the tensioning wheel 42 tensions the printed product 9, and makes the side of the printed product 9 parallel and aligned with the suction groove 611.

[0037] Specifically, Figure 4 As shown, a suction groove 611 is provided on the sliding seat 61. Figure 2As shown, when the tensioning wheel 42 tensions the printed product 9, the suction groove 611 on the sliding seat 61 is parallel to and aligned with the side of the printed product 9. At this time, the dust adhering to the printed product 9 can be further adsorbed and removed through the vacuum tube 62 and the suction groove 611, thereby avoiding the problem of subsequent wrinkles caused by the dust adhering to the printed product 9. Secondly, since the pressure wheel 43 is blown in a positive direction through the air permeable plate 52, and the suction groove 611 is located on the side of the printed product 9 for suction, that is, the air flow flows along the surface of the printed product 9 and then leaves along the side, and the flow of the air flow is used to pull the printed product 9 to unfold for subsequent leveling and rolling, thereby further improving the rolling flatness of the printed product 9.

[0038] The vacuum tube 62 is connected to an external vacuum pump, which will not be described in detail here.

[0039] As an embodiment further provided by the present invention, the sliding seat 61 is slidably disposed on the rotating frame 41, and an exhaust hole 612 connected to the vacuum tube 62 is provided on the sliding seat 61, a connecting hole 431 connected to the interior of the pressure wheel 43 is provided, and a through hole 411 coaxially connected to the connecting hole 431 is provided on the rotating frame 41, and the sliding seat 61 is driven to slide so that the exhaust hole 612 is aligned and connected with the through hole 411.

[0040] Specifically, Figure 3 As shown, the sliding seat 61 is slidably arranged on the rotating frame 41, as shown in FIG. Figure 4 As shown, an exhaust hole 612 is provided on the sliding seat 61. When the winding work is not performed, the sliding seat 61 can be slid on the rotating frame 41 to allow the exhaust hole 612 to move to align with and connect with the through hole 411. At this time, the vacuum tube 62 can be opened to allow the exhaust hole 612 to generate suction, thereby adsorbing and removing dust in the pressure wheel 43, avoiding the problem of clogging of the air permeable plate 52 and causing a slowdown in the flow rate, thereby increasing the stability of the air permeable plate 52.

[0041] As an embodiment further provided by the present invention, a sliding groove 613 is provided on the sliding seat 61, and a sliding portion 412 is symmetrically provided on the rotating frame 41. The sliding portion 412 is slidably provided in the sliding groove 613, and the sliding seat 61 is driven to slide so that the exhaust hole 612 slides parallel to the sliding portion 412.

[0042] Specifically, a sliding groove 613 is provided on the sliding seat 61, and a sliding part 412 is symmetrically provided on the rotating frame 41. The sliding part 412 is slidably arranged in the sliding groove 613. The sliding seat 61 can be pushed by hand to make the sliding groove 613 slide on the sliding part 412, thereby improving the sliding stability of the sliding seat 61. Secondly, since the air suction hole 612 slides parallel to the sliding part 412, when the winding work is performed, the sliding seat 61 is located in the default position. At this time, the air suction hole 612 is aligned with the sliding part 412. The suction force of the vacuum tube 62 makes the air suction hole 612 aligned and adsorbed on the sliding part 412, thereby realizing the self-locking of the sliding seat 61 during the winding process, thereby increasing the stability of use.

[0043] As an embodiment further provided by the present invention, the rotating frame 41 is made of polyphenylene sulfide plastic.

[0044] Specifically, the rotating frame 41 is made of polyphenylene sulfide plastic to reduce its weight while increasing the high temperature resistance of the rotating frame 41 and prolonging the service life of the rotating frame 41 .

[0045] As an embodiment further provided by the present invention, the pressure wheel 43 is made of polyphenylene sulfide plastic.

[0046] Specifically, the clamping wheel 43 is made of polyphenylene sulfide plastic to reduce its weight while increasing the high temperature resistance of the clamping wheel 43 and improving the service life of the clamping wheel 43 .

[0047] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
