[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0041] like Figure 1 to Figure 2 As shown, the utility model provides an improved laminating machine feeding device, including a frame 10, and the frame 10 is used to carry various mechanisms and parts. A film feeding unit 50 is arranged below the frame 10, and the function of the film feeding unit 50 is to roll the film material and output the film material. The film material here is a double-layer film folded once, that is, one side of the entire film is connected to each other, and the cross-section of the entire film material is V-shaped. A film pulling unit 20 for pulling the film material is slidably arranged at one end of the frame 10 to pull and traction the film material. A film cutting unit 30 for bonding and cutting the film material is slidably arranged at the other end of the frame 10 away from the film pulling unit 20. A power unit 40 for driving the film pulling unit 20 and the film cutting unit 30 to slide relative to each other is arranged below the film pulling unit 20 and the film cutting unit 30.

[0042] like Figures 1 to 3As shown, the film pulling unit 20 includes a first fixing frame 201, on which a plurality of clamping components 202 for clamping the film material are arranged, and the clamping components 202 are used to clamp the film material. A film hook component 203 for maintaining the opening of the film material is arranged on the first fixing frame 201. Because one side of the film material is not closed, an opening is required for the product to be placed, so the film hook component 203 is placed between the openings to prevent closing, and in the process of pulling, it also plays an auxiliary pulling role on the opening area of ​​the film material.

[0043] There are two clamping assemblies 202 and they are located on the same side of the hook film assembly 203, wherein one clamping assembly 202 close to the hook film assembly 203 is fixedly arranged on the first fixed frame 201, and the other clamping assembly 202 is slidably arranged on the first fixed frame 201. In this way, the movable clamping assembly 202 can adjust the position according to the film materials of different widths to meet the clamping of different positions, thereby increasing the applicability of the feeding device. The specific structure of the clamping assembly 202 includes a third base 2021, a second cylinder 2022 is fixedly arranged on the third base 2021, a clamping claw 2023 is fixedly arranged and driven on the second cylinder 2022, a first slider 205 is fixed under the third base 2021, and a first slide rail 206 for the first slider 205 to slide is arranged on the first fixed frame 201. The clamping assembly 202 includes a drive motor 204 for driving and positioning the first slider 205 on the first slide rail 206 as a power source for the sliding clamping assembly 202. The driving motor 204 is a synchronous motor and is vertically arranged upward. The synchronous motor drives a synchronous belt, and the synchronous belt is connected to the first slider 205. The synchronous belt moves under the rotation of the driving motor 204, thereby achieving the purpose of driving and positioning the first slider 205.

[0044] A sensing sheet 207 is fixedly mounted on the first slider 205, and a photoelectric sensor 208 is mounted on the first fixing frame 201 at one end away from the hook film assembly 203. Photoelectric sensing is used to determine the position of the clamping assembly 202 and prevent the danger caused by separation.

[0045] like Figure 4 and Figure 7 As shown, the specific structure of the hook film assembly 203 also includes a first base 2031, on which a first cylinder 2032 is fixedly arranged, and the first cylinder 2032 is fixedly connected to a second base 2033 along the film material movement direction, and a hook claw 2034 with an L-shaped front end is fixedly arranged on the second base 2033. A third cylinder 2035 is fixedly arranged on the first fixed frame 201 along the vertical film material movement direction, and the output end of the third cylinder 2035 is fixedly connected to the first base 2031.

[0046] A layered plate 304 for fixing the film opening is provided at the gap between the cutting assembly 302 and the heat sealing assembly 303. The layered plate 304 is fixed at one end and movable at the other end. The fixed end is thickened and provided with a receiving cavity 3041 for accommodating the hook claw member 2034. The layered plate 304 is detachably provided with a plurality of adjustment rods 3042, and the adjustment rods 3042 are provided with a clearance groove 3043 adapted to the clamping claw member 2023. The hook claw member 2034 is pushed out by the push of the third cylinder 2035. When it moves to the corresponding position, the hook claw member 2034 retracts into the receiving cavity 3041. At this time, the L-shaped notch of the hook claw member 2034 just abuts against the opening side of the film material, so that the film material opening is prevented from closing, which facilitates the smooth pushing of the product in the subsequent process and increases the work efficiency.

[0047] After the film is bonded and cut, it is sleeved on the outside of the layered plate 304, so the recess 3043 is needed to allow the clamping jaws 2023 to smoothly clamp the film when the film is sleeved, so as to smoothly pull out the film to be set in length.

[0048] like Figure 5 As shown, the film cutting unit 30 includes a second fixing frame 301, and the second fixing frame 301 is movably provided with a cutting component 302 and a heat sealing component 303. The cutting component 302 and the heat sealing component 303 can abut against each other for heating and cutting the film material. The function of this part is to heat-seal and bond the two layers of film by the heat sealing component 303 when the required length is selected, and at the same time, the film is cut and separated by the cutter on the cutting component 302. In this way, one action can complete two functions on the film, improve work efficiency, and save equipment space. When a unit of film material is pulled down, bonding and cutting are performed again, so that the heat sealing of the three sides of the film is completed, and only one side of the unclosed opening is left for the placement of the gift box in the subsequent process.

[0049] like Figure 6 As shown, the power unit 40 also includes a first motor 401, and the output shaft of the first motor 401 is connected to a bidirectional screw 402, and the two ends of the bidirectional screw 402 are slidably provided with support seats 403 for fixing the film-drawing unit 20 and the film-breaking unit 30. Second slide rails are arranged in parallel on both sides of the bidirectional screw 402, and a second slider 404 for fixing the film-drawing unit 20 and the film-breaking unit 30 is arranged on the second slide rail. Through the rotation of the first motor 401, under the action of the positive and negative bidirectional screw 402, the film-drawing unit 20 and the film-breaking unit 30 move toward each other, so that the stroke of the film-drawing material becomes shorter, further increasing the efficiency. The power unit 40 is placed below the film-drawing unit 20 and the film-breaking unit 30. In addition to providing support, it also further optimizes the overall structure, making the equipment more compact and reducing the occupied space.

[0050] like Figure 5As shown, a lifting assembly 305 is provided above the cutting assembly 302 and below the heat sealing assembly 303. The lifting assembly 305 is provided to move against each other, shorten the working stroke, and increase the working efficiency. A guide roller 306 is provided between the film feeding unit 50 and the layering plate 304, so as to guide the film, adjust the tension of the film material, and facilitate the direction of the film material in different spaces.

[0051] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
