Therefore, the bag carrying station is required to be reserved, so that the transverse size of the equipment is large, and the equipment is not friendly to factories with small factory areas. Therefore, improvements in the art are needed.

Therefore, in order to solve the problems, the utility model discloses a linear film coating machine which comprises a box pushing device, a processing table, a film feeding device, a film pulling device and a cutter device. The film feeding device is used for conveying the plastic packaging film, the plastic packaging film is pulled to the processing table through the film pulling device, at the moment, the box pushing device pushes the box to be subjected to plastic packaging into the plastic packaging film, and finally the cutter device cuts corners of the plastic packaging film for sealing. Therefore, the linear film coating machine provided by the utility model does not need separate film making and film carrying processes, so that the production efficiency is improved, and the equipment volume is reduced.

For ease of understanding, the following detailed description of the embodiments of the present application is provided with reference to the accompanying drawings.

In an embodiment of the present utility model, referring to fig. 1 and 2, the linear film coating machine provided in the embodiment of the present application includes a box pushing device 100, a processing table 200, a film feeding device 500, a film pulling device 300, a film opening device 400 and a cutter device, wherein the film feeding device 500 is located at a first side 210 of the processing table 200, and the film pulling device 300 is used for clamping an end portion of the plastic package film sent by the film feeding device 500 and pulling the plastic package film to a second side 220 of the processing table 200; the first side 210 and the second side 220 are opposite sides of the processing station 200; the film opening device 400 is used for opening the plastic package film; the box pushing device 100 is used for pushing a box to be coated into the processing table 200 so as to enable the box to enter the plastic packaging film; the cutter device is used for cutting off the plastic package film pulled out by the film pulling device 300.

In this embodiment, the plastic packaging film used is not a finished plastic packaging bag, but is a double-layered plastic packaging film, and the plastic packaging film needs to be heat-sealed by a cutter device to form a bag. Specifically, the processing table 200 is a table for coating a cassette, and most of the processes are performed around the processing table 200. Referring to fig. 1 to 3, the processing table 200 is provided with a first side 210 and a second side 220 opposite to each other, and a third side 230 and a fourth side 240 perpendicular to the first side 210 and the second side 220, and the film feeding device 500 is located on the first side 210 of the processing table 200 and is used for conveying the plastic package film to the processing table 200; the cutters include a first cutter 600 and a second cutter 610, the first cutter 600 being disposed above the first side 210 of the processing station 200 and the second cutter 610 being disposed above the fourth side 240 of the processing station 200.

Thus, at the film feeding device 500, the plastic sealing film is fed to the first side 210 of the processing table 200, and the first cutting device 600 has performed the first hot cutting of the double-layered plastic sealing film in the previous processing procedure, at which time one end of the plastic sealing film has been sealed. Then, the film pulling device 300 pulls the sealed side of the plastic sealing film to the second side 220 of the processing table 200, and the first cutting device 600 performs a second hot cutting on the plastic sealing film located at the first side 210 of the processing table 200. And after twice hot cutting, both ends of the plastic packaging film are sealed. Then, the double-layer plastic packaging films are opened by the film opening device 400 to enable the box to enter the space, and the box is pushed between the double-layer plastic packaging films by the box pushing device 100. Finally, the cassette pushed into the plastic film continues to be pushed by the cassette pushing device 100 in the process traveling direction.

Therefore, the linear film coating machine provided in the embodiment of the application omits the film carrying device, and the film pulling device 300 directly pulls the plastic packaging film sent by the film sending device 500 onto the processing table 200. On the one hand, the film carrying device is omitted, so that the transverse movement distance of the film carrying device is reduced, the whole equipment is narrower in size, and the film carrying device is more friendly to factories with smaller factory building areas. On the other hand, the film carrying time of the film carrying device is not needed, so that the processing efficiency is improved, and the equipment is more efficient.

It should be noted that, the film pulling device 300 is used to pull the plastic package film from the first side 210 to the second side 220 of the processing table 200 after clamping, and various embodiments of the present application are provided as follows to ensure the horizontal movement of the film pulling device 300. In an embodiment of the present utility model, referring to fig. 1 to 3, a processing table 200 is provided with a channel 250, a film pulling device 300 is provided with a first moving mechanism 310, and after the film pulling device 300 clamps a plastic package film, the first moving mechanism 310 drives the film pulling device 300 to move from a first side 210 to a second side 220 in the channel 250.

It should be noted that, referring to fig. 4, the first moving mechanism 310 further includes a first sliding rail 311 and a second sliding rail 312, the clamping portion 330 and the film pulling hook 340 are slidably connected to the first sliding rail 311, and two ends of the first sliding rail 311 are slidably connected to the second sliding rail 312. The clamping parts 330 can slide on the first slide rail 311, so that the distance between the two clamping parts 330 can be adjusted to meet the requirements of clamping plastic package films with different specifications. Meanwhile, the first moving mechanism 310 may drive the first sliding rail 311 to move on the second sliding rail 312, that is, may drive the clamping portion 330 and the film pulling hook 340 to move on the second sliding rail 312 at the same time, so as to pull the plastic package film from the first side 210 to the second side 220 of the processing table 200.

It should be further noted that, after the film pulling device 300 pulls the plastic package film from the first side 210 to the second side 220 of the processing table 200, the film pulling device 300 can return to the first side 210 of the processing table 200 after the completion of the box pushing process and the returning of the box pushing device 100 to the original position, which increases a lot of unnecessary waiting time. In this embodiment, for improving efficiency, a lifting mechanism 320 is added to the clamping portion 330 and the film pulling hook 340 by utilizing the space in the height direction, so that the clamping portion 330 and the film pulling hook 340 can be returned from the lower side of the processing table 200 while the box pushing process is performed, and a large amount of unnecessary working time is reduced.

In an embodiment of the present utility model, referring to fig. 4, the clamping portion 330 and the film pulling hook 340 are both provided with a lifting mechanism 320, and after the film pulling device 300 moves to the second side 220, the lifting mechanism 320 drives the clamping portion 330 and the film pulling hook 340 to descend below the processing table 200, and the first moving mechanism 310 drives the film pulling device 300 to return to the first side 210 from below the processing table 200. In this embodiment, the lifting mechanism 320 and the first moving mechanism 310 are added to cooperate, when the box pushing device 100 pushes the box into the plastic packaging film, the lifting mechanism 320 drives the clamping portion 330 and the film pulling hook 340 to descend below the processing table 200, and then the first moving mechanism 310 restores the film pulling device 300 to the first side 210 of the processing table 200, so that the two steps are performed simultaneously, the working time is shortened, and the efficiency is greatly improved.

It should be noted that, because the thickness of the plastic packaging film is relatively thin, a clamping mechanism needs to be added in the film pulling device 300 to clamp the plastic packaging film to prevent slipping. In the embodiment of the present application, the manner of clamping the plastic package film is not limited. For ease of understanding, a preferred embodiment is provided below.

In a preferred embodiment of the present utility model, the film pulling device 300 includes a clamping portion 330; the clamping part 330 is provided with a rubber pad or a sucker which is used for clamping the plastic packaging film.

In this embodiment, referring to fig. 4, a clamping jaw 331 and a small driving mechanism for controlling the opening and closing of the clamping jaw 331 are disposed on the clamping portion 330, wherein a contact surface between the clamping jaw 331 and the plastic sealing film is a rubber pad or a suction cup. Therefore, the clamping jaw 331 is controlled to open and close by the small driving mechanism to clamp the plastic packaging film, and the plastic packaging film can be stably pulled by utilizing the friction force of rubber or the suction force of the sucker.

It should be noted that, because the plastic packaging films are stacked in two layers at the beginning, before the box is pushed into the plastic packaging films, the two layers of stacked plastic packaging films need to be separated and kept in a separated state, so that a certain distance is formed between the two layers of plastic packaging films, thereby facilitating subsequent operations.

In one embodiment of the present utility model, the film pulling hook 340 further includes a traversing mechanism, where the traversing mechanism is used to cooperate with the first moving mechanism 310 to drive the film pulling hook 340 to extend into the plastic package film opening.

In this embodiment, referring to fig. 1 to 4, the front end of the film pulling hook 340 is configured as a hook shape, and the film pulling hook 340 has a certain thickness, so that the film pulling hook 340 hooks the end of the plastic package film sealed by the hot knife while separating the double-layer plastic package film, and cooperates with the clamping portion 330 to pull the plastic package film to the second side 220 of the processing table 200.

It should be noted that, before film pulling, the sealed end of the plastic sealing film shields the straight line of the film pulling hook 340, so that the film pulling hook 340 needs to bypass the plastic sealing film to enter the opening of the plastic sealing film and hook the opening. In this step, the film pulling hook 340 needs to be moved on the first sliding rail 311 to a position capable of avoiding the plastic packaging film under the driving of the traversing mechanism, then the first moving mechanism 310 drives the first sliding rail 311 to move on the second sliding rail 312 to be close to the plastic packaging film, then the film pulling hook 340 is moved on the first sliding rail 311 to enter the opening of the plastic packaging film to hook the plastic packaging film under the driving of the traversing mechanism, and finally the clamping part 330 is matched to clamp and pull the plastic packaging film.

It should be further noted that, when the film feeding device 500 conveys the double-layer plastic package film to the first side 210 of the processing table 200, the plastic package film needs to be layered in advance to enable the film pulling hook 340 to enter, which requires a film separating mechanism to separate the double-layer plastic package film on the first side 210 of the processing table 200. In the embodiment of the present application, the manner of separating the plastic packaging film is not limited. For ease of understanding, a preferred embodiment is provided below.

In one embodiment of the present utility model, the film pulling device 300 further includes a film separating rod 350, and the film separating rod 350 is located downstream of the film feeding device 500; the film separating rod 350 is used to separate the plastic sealing film so that the film pulling hook 340 can extend into the plastic sealing film.

In the present embodiment, referring to fig. 1 and 6, the film separating rod 350 is disposed downstream of the film feeding device 500, i.e., between the film pulling device 300 and the film feeding device 500. One side of the film separating rod 350, which is in initial contact with the plastic packaging film, is provided with a gradient, before the equipment is started, the double-layer plastic packaging film is firstly separated and placed on the upper surface and the lower surface of the film separating rod 350, then the double-layer plastic packaging film is continuously separated by utilizing one end of the thinner slope bottom 352, and then reaches the slope top 353 through the slope, at the moment, a distance similar to the thickness of the film separating rod 350 is formed between the double-layer plastic packaging films, and the film pulling hooks 340 are convenient to extend into the space between the plastic packaging films.

It should be noted that, since the film pulling hook 340 needs to extend into the sealed end of the plastic packaging film, a space needs to be reserved at the side of the film separating rod 350 facing the film pulling hook 340 for the film pulling hook 340 to extend into.

In one embodiment of the present utility model, a groove 351 is formed on the side of the film separating rod 350 facing the film pulling hook 340, and the groove 351 is used for the film pulling hook 340 to extend into and pull out the plastic package film.

In this embodiment, referring to fig. 1, 4 and 6, since the film pulling hook 340 needs to enter the space formed between the two plastic sealing films from the sealed end of the plastic sealing film, the groove 351 needs to be configured to adapt to the shape of the front end of the film pulling hook 340, so that the film pulling hook 340 stretches into the groove 351 to pull the sealed end of the plastic sealing film, and then the plastic sealing film is pulled together with the film pulling device 300.

It should be noted that, because the thickness of the film separating rod 350 and the film pulling hook 340 is limited, and the height of the box requiring the film coating is often greater than the thickness, the distance between the two plastic films needs to be increased by providing the additional film opening device 400, so as to adapt to the boxes with various specifications.

In one embodiment of the present utility model, the film opening device 400 is further included, and the film opening device 400 includes a film opening assembly 410 and a second movement mechanism 420; the film opening assembly 410 is used for separating film openings of the plastic packaging film; the second movement mechanism 420 is used for driving the membrane opening assembly 410 to separate the membrane openings.

The lower film opening part 412 is used for clamping and fixing the lower plastic packaging film so that the upper film opening part 411 lifts the upper plastic packaging film, thereby forming a larger opening. Thus, the film opening assembly 410 is driven by the second moving mechanism 420 to move towards the direction of the processing table and is connected to the plastic packaging film from the film pulling device 300, the lower film opening member 412 clamps the lower plastic packaging film, and the upper film opening member 411 drives the upper plastic packaging film to be lifted to the height where the box can enter through the second moving mechanism 420. After the box pushing device 100 pushes the box between the plastic sealing films, the film opening assembly 410 is restored to the initial position under the drive of the second movement mechanism 420, and the next film opening operation is prepared.

It should be noted that, when the box is placed between the two plastic sealing films, a subsequent sealing process is required to complete the complete film coating operation, so in one embodiment of the present utility model, a cutter device is added, including a hot cutter for cutting the plastic sealing film; the hot cutter completes bag making and edge sealing while cutting the plastic packaging film.

In the present embodiment, referring to fig. 1 to 3, the cutter device includes a first cutter device 600 and a second cutter device 610, the first cutter device 600 is disposed above the first side 210 of the processing table 200, and the second cutter device 610 is disposed above the fourth side 240 of the processing table 200. In the operation state of the apparatus, when the plastic sealing film is conveyed to the first side 210, the first cutter device 600 performs a first hot-cutting plastic sealing on the plastic sealing film, then the film pulling device 300 pulls the sealed end of the plastic sealing film to the second side 220 of the processing table 200, the first cutter device 600 performs a second hot-cutting sealing on the plastic sealing film located at the first side 210 of the processing table 200, then the box pushing device 100 pushes the front end of the box located in the box pushing direction to the fourth side 240 of the processing table 200, at this time, the second cutter device 610 performs a third hot-cutting plastic sealing on the plastic sealing film, and finally the box pushing device 100 continues to push the rear end of the box located in the box pushing direction to the fourth side 240 of the processing table 200, at this time, the second cutter device 610 performs a fourth hot-cutting plastic sealing on the plastic sealing film. The four sides of the plastic film are sealed by hot cutting, and the box pushing device 100 continues to push the plastic film to perform the subsequent corner cutting process.

In order to maintain consistency of the coating process, the film feeding device 500 has both a storage function and a conveying function, so that frequent replacement of the plastic film roller is avoided.

In one embodiment of the present utility model, the film feeding device 500 includes a rotating wheel 510 mechanism, where the rotating wheel 510 mechanism includes a rotating wheel 510 coated with a plastic film and a rotating motor; the rotating motor is used for driving the rotating wheel 510 to rotate for film feeding.
