[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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.

[0024] The present invention provides two technical solutions:

[0025] Figures 1-5 The first implementation manner is shown: A carton film covering packaging device includes a first belt conveyor 1, a vertical plate 2, and a mounting frame 5. A mounting plate 11 is installed at the bottom of the first belt conveyor 1. The number of vertical plates 2 is set to two. Hot melt assemblies 3 are provided on the opposite sides of the two vertical plates 2. A moving assembly 4 is arranged between the two vertical plates 2 for replacing the film roll. Rotating assemblies 6 are provided on both the mounting frame 5 and the mounting plate 11 for driving the film roll to rotate;

[0026] The moving assembly 4 includes a first motor 41 and synchronous pulleys 42. The number of synchronous pulleys 42 is set to two and they are vertically distributed on the outer surface of one of the vertical plates 2 facing outwards. A lead screw 44 is installed at the end of the synchronous pulley 42. The outer surface of the lead screw 44 movably penetrates through the outer surface of one of the vertical plates 2 and extends to the other side. A moving frame 45 is threadedly installed on the outer wall of the lead screw 44. A plurality of unwinding rollers 46 are installed on the inner wall of the moving frame 45. By driving the synchronous pulley 42 and the lead screw 44 to rotate through the first motor 41, the moving frame 45 moves, so as to realize the position adjustment of the film roll on the unwinding roller 46 and facilitate the quick replacement of the film roll.

[0027] On the left and right outer surfaces of the first belt conveyor 1, first guide plates 12 are installed. A second belt conveyor 13 is arranged downstream of the first belt conveyor 1. On the surface of the second belt conveyor 13 facing the first belt conveyor 1, a support plate 14 is installed. On the left and right outer surfaces of the second belt conveyor 13, second guide plates 15 are installed. A roller conveyor 8 is arranged downstream of the second belt conveyor 13. On the top of the roller conveyor 8, a heat shrinker 81 is installed. At a position above the support plate 14 on the inner top of the mounting frame 5, a fourth cylinder 7 is installed. The telescopic end of the fourth cylinder 7 is equipped with a fusing knife 71. The fusing knife 71 is arranged in parallel with the support plate 14. The first guide plates 12 and the second guide plates 15 guide the unfolded part of the film to avoid deviation. The fourth cylinder 7 pushes the fusing knife 71 to cooperate with the support plate 14, so as to fuse and cut the film, and complete the preliminary film covering of the carton. The heat shrinker 81 performs heat shrinkage treatment on the carton after film covering, so that the film fits tightly on the carton.

[0028] At a position above the two vertical plates 2, two first limiting rods 21 are installed. At a position below the two vertical plates 2, a second limiting rod 22 is installed. The two vertical plates 2 limit the movement of the moving frame 45 to ensure the stability of the device operation. Among them, the first limiting rod 21 and the second limiting rod 22 play a guiding role for the film roll.

[0029] Figures 1-5 The second implementation mode is shown. The main difference from the first implementation mode is that: both of the two hot melting assemblies 3 include a first cylinder 31, a hot melting plate 32 and a fixing plate 33. The first cylinder 31 is installed on the vertical plate 2 through a bracket. The hot melting plate 32 is installed at the telescopic end of the first cylinder 31. The fixing plate 33 is installed on the vertical plate 2, and the fixing plate 33 is arranged in parallel with the hot melting plate 32 front and back. The first cylinder 31 pushes the hot melting plate 32 to cooperate with the fixing plate 33, so as to fuse the joint of the new film roll and complete the pre-installation, improving the efficiency of replacing the film roll.

[0030] The first motor 41 is fixedly installed on the surface of one of the vertical plates 2 facing the outside. The output shaft end of the first motor 41 is fixedly connected with one of the synchronous pulleys 42. A synchronous belt 43 is connected in transmission between the two synchronous pulleys 42. A guide rod 47 penetrates through the lower part of the surface of the moving frame 45 in a sliding manner. The guide rod 47 is arranged in parallel with the lead screw 44. The two ends of the guide rod 47 are respectively fixedly installed on the two vertical plates 2. The first motor 41 drives the lead screw 44 to rotate through the synchronous pulley 42 and the synchronous belt 43. The guide rod 47 ensures the smooth movement of the moving frame 45 and realizes the accurate position adjustment of the film roll on the uncoiling roller 46.

[0031] The two rotating components 6 each include a second cylinder 61, wherein one second cylinder 61 is mounted on the mounting plate 11, and the other second cylinder 61 is mounted on the inner top of the mounting frame 5. The telescopic ends of the two second cylinders 61 are fixedly mounted with a telescopic frame 62, and a third cylinder 63 is mounted on one side of the telescopic frame 62. The telescopic end of the third cylinder 63 slides through the telescopic frame 62 and extends inwardly, and a pressure plate 64 is rotatably provided at the telescopic end of the third cylinder 63. A second motor 65 is mounted on the other side of the telescopic frame 62, and the output shaft of the second motor 65 movably penetrates the telescopic frame 62 and extends inwardly, and a turntable 66 is mounted on the output shaft of the second motor 65. The second cylinder 61 can adjust the height of the telescopic frame 62, and the third cylinder 63 drives the pressure plate 64 to clamp the film roll, and the second motor 65 drives the turntable 66 to rotate out the film, thereby cooperating with the conveyor to realize the carton lamination.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] When in use, the third cylinder 63 in the two rotating assemblies 6 drives the pressing plate 64 to move inward to clamp the film roll, and the second motor 65 drives the turntable 66 to rotate, so that the two film rolls can be output and the packaging box is transported on the first belt conveyor 1 and the second belt conveyor 13 to wrap the film on the carton. As the packaging box moves to the second belt conveyor 13, the fourth cylinder 7 pushes the fuse knife 71 to move downward, and the fuse knife 71 contacts the support plate 14 to fuse and cut the film roll, so that the carton completes the initial coating. After that, the carton is transported to the inside of the heat shrink machine 81 together with the film. The heat shrink machine 81 generates high temperature to shrink the film and fit tightly to the carton to achieve the coating effect. In the continuous coating production process, the staff uses the time gap of production to pre-place new film rolls on the upper and lower take-off rollers 46 and on the outward side, and pull out the upper and lower two rolls respectively. The joint of each film roll is placed between the hot melting plate 32 and the fixed plate 33, and then the hot melting plate 32 is pushed to move by the first cylinder 31 and contact with the fixed plate 33. Under the action of the high temperature of the hot melting plate 32, the joints of the upper and lower film rolls are fused together, thereby completing the pre-installation of the two film rolls. After the original two film rolls are used up, the pressure plate 64 is retracted and the film roll is no longer fixed. The telescopic frame 62 is pulled up to a suitable height by the second cylinder 61. Then, the two screw rods 44 are driven to rotate synchronously by the first motor 41. At this time, the moving frame 45 moves and moves the used film roll on the take-off roller 46 to the outside side of the device. At the same time, the new film roll on the outside side is moved to the middle position of the device, thereby achieving the effect of quick replacement. The operation is simple and convenient, and the downtime is greatly reduced. After that, the used film roll is removed and a new film roll is installed.
