[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0031] like Figure 1-13 As shown, a film-coating machine includes: a frame 100, a loading platform 110 at the center of the frame 100 in the height direction, a vertically extendable lifting mechanism 300 at the center of the loading platform 110, the lifting mechanism 300 being installed at the bottom of the frame 100, and material-carrying mechanisms 200 on the loading platforms 110 on both sides of the lifting mechanism 300, the material-carrying mechanisms 200 transferring the products to be coated from one end of the loading platform 110 to the other end, and side-mounted material-lifting mechanisms 800 at the center of the frame 100 on both sides of the material-carrying mechanisms 200. The material feeding mechanism 800 is positioned opposite to the lifting mechanism 300. The frame 100 is provided with lifting and sliding structures on both sides. A bag sealing mechanism 400 is provided across the lifting and sliding structure. The bag sealing mechanism 400 is symmetrically arranged on both sides of the corresponding position of the lifting mechanism 300. A bag feeding mechanism 500 is provided at the top of the frame 100. A bag tube frame 510 is provided on one side of the frame 100. The bag feeding mechanism 500 guides the bag material on the bag tube frame 510 to the top of the frame 100. The bottom of the outlet of the bag feeding mechanism 500 is provided with a top sealing mechanism 600.

[0032] In a preferred embodiment, the material loading mechanism 200 includes two material loading plates 210, each with a feeding support rod 220 and a discharging support rod 230 at both ends, and each with a horizontal moving mechanism at the bottom.

[0033] In a preferred embodiment, the pull-to-seal bag mechanism 400 includes: symmetrically arranged pull-to-seal bag mounting seats 410, the two ends of which are connected to an up-and-down lifting mechanism, a heat-sealing and bag-cutting structure 430 on the pull-to-seal bag mounting seat 410, and a bag-suction structure 420 at the lower part of the heat-sealing and bag-cutting structure 430.

[0034] It should be noted that the side top feeding mechanism 800 and the pull-sealing bag mechanism 400 are respectively paired and symmetrically arranged around the lifting mechanism 300. The heat-sealing and bag-cutting structure 430 and the bag suction structure 420 are both installed on the horizontal telescopic structure, so that after adsorbing the flat double-layer bag tube, the two sides shrink to form an open bag tube structure, which is convenient to be put on the product to be filmed.

[0035] In a preferred embodiment, the suction bag structure 420 is a vacuum suction cup 421, and the vacuum suction cup 421 is provided with pressure claws 422 on its outer side.

[0036] It should be noted that the pressure claw 422 is equipped with an upper and lower telescopic cylinder and a horizontal telescopic cylinder, so that when it is not working, it retracts to the inner side below the vacuum suction cup 421, and when it is working, it extends to the outer side of the surface of the vacuum suction cup 421 and presses it, thereby mechanically pressing the contents adsorbed by the bag film.

[0037] In a preferred embodiment, the lifting mechanism 300 includes: a lifting mechanism base 310, a primary lifting body 320 is installed inside the lifting mechanism base 310, a secondary lifting body 330 is installed inside the primary lifting body 320, and a pair of lifting material wheels 340 are provided on the top of the secondary lifting body 330.

[0038] It should be noted that the lifting mechanism 300 is usually lower than the lowest point of the feeding support rod when it is at its lowest point, and the position of the lifting mechanism 300 when it is at its highest point corresponds to the position of the side lifting mechanism 800.

[0039] In a preferred embodiment, the lifting wheel 340 is equipped with a wheel power unit 341.

[0040] It should be noted that the material-carrying wheel power device 341 is an electric motor. The material-carrying wheel power device 341 is connected to the lifting material-carrying wheel 340 through a transmission belt. One of the lifting material-carrying wheels 340 has a pulley that cooperates with the transmission belt. This structure allows the radial film bag to be pressed and flattened by the weight of the product to be filmed after the first layer of film bag is installed, which facilitates the installation of the second layer of film bag.

[0041] In a preferred embodiment, a bag vacuum suction device 350 is installed inside the lifting mechanism 300. The bag vacuum suction device 350 is mounted on the lifting structure and can extend or retract from the top of the lifting mechanism 300.

[0042] It should be noted that the vacuum suction device 350 for the bag body usually has an air extraction tube, which has a certain length so that it can be inserted into the middle of the bag body to extract air.

[0043] In a preferred embodiment, a side bag-pulling structure 700 is installed on the frame 100 on one side of the side top material mechanism 800, and the side bag-pulling structure 700 fixes the bag tube to the side.

[0044] In a preferred embodiment, each of the side-pull bag structures 700 has a plurality of bag clips 710 arranged vertically at intervals. The bag clips 710 are mounted on a horizontal telescopic device, and the side-top material mechanism 800 is also provided with a telescopic structure.

[0045] It should be noted that the side top material mechanism 800 described on each side is arranged in pairs on both sides of the side bag pulling structure 700, thereby avoiding the vertical movement path of the side bag pulling structure 700. The side bag pulling structure 700 is provided with a vertical lifting structure, which can be achieved by the cooperation of the mounting base as a slide groove and a transmission belt, thereby cooperating with the pulling and opening effect of the bag sealing mechanism 400.

[0046] In a preferred embodiment, the bag holder 510 is provided with servo lifting structures at both ends, so that the bag holder 510 can be raised and lowered in the vertical direction.

[0047] It should be noted that this structure makes the height of the bag holder 510 adjustable. It can be lowered when it needs to be filled, making it easier for operators to use, and raised during normal bagging to prevent interference with the products to be bagged.

[0048] Brief description of working principle: The feeding mechanism places the product to be filmed onto the feeding support rods 220 of the loading mechanism 200. The two feeding support rods 220 support the annular surface of the disc-shaped product, moving and transporting the product to the position of the lifting mechanism 300. The lifting mechanism 300 lifts the product. The bag-sealing mechanism 400 moves upward to suction and pull down the flat bag tube at the bag feeding mechanism 500. The suction here is achieved by the vacuum suction cup 421 sucking the outer side of the bag film and pressing the outer side with the pressure claw 422, forming a two-stage fixation to increase stability. During the process, the vacuum suction cup 421 contracts with the telescopic structure, separating the film bags on both sides, thus opening the bag tube to be fitted onto the product during the lowering process. During the process, the top sealing mechanism 600 cuts the bag tube and performs a top seal. Then, the side lifting mechanism 800 extends horizontally to support the product. This process is for temporary support, allowing the lifting mechanism 300 to move down away from the film bag. The lifting mechanism descends, pulling the bag... The vacuum suction device 350 extends to vacuum the top-sealed film bag. After completion, the heat-sealing and cutting structure 430 of the bag-pulling mechanism 400 moves closer to each other to perform the sealing and cutting actions. During the process, the vacuum suction device 350 retracts, and then the lifting mechanism 300 rises again, the side material feeding mechanism 800 retracts, and the lifting material loading wheel 340 rotates, driving the product to rotate circumferentially on its upper part to press the sealed film bag. Then, the bag-pulling and sealing action is performed again to achieve the effect of double-layer film covering. After completion, the material loading mechanism 200 returns to its position so that the discharge support rod 220 corresponds to the position of the lifting mechanism 300. The lifting mechanism 300 descends to place the product on the discharge support rod 230, and at the same time, another product to be covered is placed on the infeed support rod 230. Then, the material loading mechanism 200 moves, and the new product is covered. The unloading mechanism is used to remove and transfer the completed product. The entire process realizes unmanned, standardized and efficient operation.
