The following will be described by referring to the drawings Figures 1-8 The described embodiments are exemplary and are intended to explain the embodiments of the utility model, and cannot be understood as a limitation of the utility model.

For ordinary skilled in the art, the specific meaning of the above terms in the embodiments of the utility model can be understood according to the specific circumstances.

[0037] In an embodiment of the utility model, as Figures 1-8As shown, an automatic laminating machine is provided for applying film to products. It includes a base 100, an input mechanism 200, a film feeding and positioning frame 120, a lifting mechanism 300, a cutting mechanism 400, a flattening mechanism 500, and an output mechanism 240. A gantry frame 110 is mounted on the base 100. The input mechanism 200 is located on the base 100 and is used to convey unlaminated products. The film feeding and positioning frame 120 is located on the base 100, and the film material is fitted onto the film feeding and positioning frame 120 for positioning and conveying the film material. A lifting mechanism 300 is mounted on the gantry frame 110. The driving end of the lifting mechanism 300 is connected downwards to two parallel support plates 310 to drive them in lifting motion. Several guide rollers 311 and a support frame 312 are provided between the two support plates 310. A guide roller 304 is provided on the front side of the support frame 312. The film passes through the bottom ends of the guide rollers 311 and the support frame 312 and acts on the lower end of the guide roller 304. An adjustment mechanism 600 is also provided on the support plate 310 to support the film. A cutting mechanism 400 is movably mounted on the support plate 310 for cutting the film after it has been coated. A flattening mechanism 500 is mounted on the gantry frame 110 and located on the other side of the lifting mechanism 300 for flattening the cut film onto the product. An output mechanism 240 is connected to the outlet end of the input mechanism 200 for conveying the coated product.

[0038] Specifically, the input mechanism 200 begins conveying uncoated products into the working area. The products first stop at a designated position, and the lifting mechanism 300 presses down, causing the guide roller 304 to press against the exit end of the film and onto the surface of the product. The input mechanism 200 continues to operate, moving the product forward using friction. Simultaneously, under the adhesive force of the film and the pressure of the lifting mechanism 300, the film is successively extracted from the film material in the film feeding and positioning frame 120, and the film is flattened onto the entire product surface. After sensing that the film application is complete, the cutting mechanism 400 moves laterally to cut and separate the applied film quickly. Then, the flattening mechanism 500 presses down to smooth the film, and finally, the output mechanism 240 sends the coated product out. The independent film feeding, positioning, cutting, and flattening mechanisms 500 ensure that each product receives precise and high-quality coating, significantly improving the overall capacity of the production line.

[0039] Furthermore, such as Figures 1-2As shown, the lifting mechanism 300 includes a lifting motor 301 and a connecting rod 302, and the gantry 110 is provided with a fixed table 303, the lifting motor 301 is installed on the fixed table 303, the driving end of the lifting motor 301 is connected with the connecting rod 302, the other end of the connecting rod 302 is connected with a downward vertical plate 305, the back end of the vertical plate 305 is slidably connected to the fixed table 303 through a sliding assembly 306; the lower end of the vertical plate 305 is connected with a cross beam, and the two ends of the cross beam are respectively connected with two support plates 310 to drive the support frame 312 to make lifting movement. Specifically, when the lifting motor 301 is started, the driving end thereof pushes the vertical plate 305 to make vertical movement in the sliding assembly 306 of the fixed table 303 through the connecting rod 302. The vertical plate 305 drives the cross beam and the support plates 310 at the two ends thereof to make synchronous lifting, so as to adjust the height of the guide roller 311, the support frame 312 and the guide roller shaft 304 to adapt to products of different thicknesses or heights, and press the guide roller shaft 304 against the film to be close to the product. The lifting mechanism 300 adopts the design of the connecting rod 302 and the sliding assembly 306, so that the whole mechanism is compact in structure and small in space occupation, which is beneficial to realizing efficient lifting function in limited equipment space. The sliding assembly 306 includes a sliding rail 307 and a sliding block 308, the sliding rail 307 is arranged on the fixed table 303, and the sliding block 308 is arranged at the back end of the vertical plate 305, the sliding block 308 is connected with the sliding rail 307, so that the vertical plate 305 is stable and accurate during lifting, and the decline of the film pasting quality caused by shaking or deflection is avoided.

[0040] Further, as shown in Figure 1 、 4 , the cutting mechanism 400 includes a cutter 410, a translation motor 420, a track, a clamping assembly 430 and a matching wheel 440, the driving end of the translation motor 420 arranged at one end of the support plate 310 is positioned at the left extreme end of the track and drives the track to rotate, the other end of the support plate 310 is provided with the matching wheel 440, and the matching wheel 440 is positioned at the right extreme end of the track; the clamping assembly 430 is sleeved on the track, and the other end of the clamping assembly 430 is connected with the cutter 410 to drive the cutter 410 to move back and forth in the horizontal direction. Specifically, when it is sensed that the product is pasted with the film, the translation motor 420 is started, and the driving end of the translation motor 420 drives the track to rotate. The track drives the clamping assembly 430 and the cutter 410 to move left and right along the horizontal direction. Since the matching wheel 440 is positioned at the right extreme end of the track, it plays a role in supporting and guiding the track to rotate, and ensures the stable operation of the track. The clamping assembly 430 and the cutter 410 move with the movement of the track, and precise cutting of the film is realized.

[0041] Further, as shown in Figure 1 、 4As shown, the cutter 410 is close to the guide roller 304, and the lowest point of the cutter 410 is lower than the lowest point of the guide roller 304. The cutter 410 is designed to be close to the guide roller 304, and the lowest point of the cutter 410 is lower than the lowest point of the guide roller 304. This means that during the cutting process, after the product film is applied, the cutter 410 can closely follow the guide roller 304 to cut along the lower film separation, ensuring accurate cutting. Because the cutter 410 is designed to be close to and slightly lower than the guide roller 304, it can precisely cut off excess film while the film adheres tightly to the product surface.

[0042] Furthermore, such as Figure 1 , 3 As shown, a retaining plate 320 is provided at the bottom of the support plate 310, and the lower cut surface of the retaining plate 320 is parallel to the product; a connecting cavity 321 is provided between the retaining plate 320 and the support plate 310, and the film passes around the guide roller 311 in sequence, passes through the connecting cavity 321, and finally acts on the lower end of the guide roller 304.

[0043] Furthermore, such as Figure 1 , 3 As shown, the adjustment mechanism 600 includes an adjustment cylinder 610 and an L-shaped plate 620. The adjustment cylinder 610 is mounted on the support plate 310, and its drive end is connected to the L-shaped plate 620 to drive the L-shaped plate 620 to move up and down. The lower plate of the L-shaped plate 620 is in close contact with the lower end of the support plate 310. The L-shaped plate 620 has a through-hole 630 at its web position. The film passes around the guide roller 311, through the through-hole 630, and through the connecting cavity 321, finally acting on the lower end of the guide roller 304. Specifically, when it is necessary to adjust the contact pressure or positional relationship between the film and the guide roller 304, the adjustment cylinder 610 is activated. Its drive end pushes or pulls the L-shaped plate 620, causing the L-shaped plate 620 to move up and down along the support plate 310. Because the L-shaped plate 620 has a through-hole 630 at its web position, the film can sequentially pass around the guide roller 311, through the through-hole 630, and continue through the connecting cavity 321, finally acting on the lower end of the guide roller 304. By adjusting the position of the L-shaped plate 620, the contact angle and pressure between the support plate 310 and the film can be changed, thereby achieving precise control over the cutting effect and film adhesion when the lifting mechanism 300 resets after cutting.

[0044] Furthermore, such as Figure 1 , 6As shown in Figure 7, the input mechanism 200 includes a rotating shaft 210, an input motor 220, and two column plates 230. The two column plates 230 are mounted on the base 100, and several parallel rotating shafts 210 are arranged between the two column plates 230. The input motor 220 is mounted on the base 100, and its drive end is connected to one of the rotating shafts 210 via a track. This rotating shaft 210 is connected to all the rotating shafts 210 via a linkage belt to drive all the rotating shafts 210 to rotate. Specifically, when the input motor 220 starts, its drive end drives one of the rotating shafts 210 to start rotating via the track. Since this rotating shaft 210 is connected to all the other rotating shafts 210 via the linkage belt, the other rotating shafts 210 will also rotate synchronously. In this way, the product mounted on the rotating shaft 210 will be continuously transported to the next designated position.

[0045] Furthermore, such as Figure 1 , 6 As shown in Figure 7, the base 100 is also provided with a limiting assembly 800, which includes a left translation plate 820, a right translation plate 830, a rotating handle 840, a screw 850, a tailstock 860, and a nut seat 810. The tailstock 860 is mounted on the base 100, and the upper end of the tailstock 860 is fixed with the right translation plate 830 passing through the rotating shaft 210. One end of the screw 850 is slidably connected to the tailstock 860, and the other end is coaxially connected to the rotating handle 840. The screw 850 is also provided with a nut seat 810 threadedly connected to it. The upper end of the nut seat 810 is provided with a left translation plate 820 passing through the rotating shaft 210. Driven by the rotating handle 840, the left translation plate 820 moves towards or away from the right translation plate 830. Specifically, when it is necessary to adjust the position of the rotating shaft 210, the screw 850 is driven to rotate by rotating the rotating handle 840. Since the screw 850 is threadedly connected to the nut seat 810, the rotation of the screw 850 is converted into linear motion of the nut seat 810. When the nut seat 810 moves, the left translation plate 820 at its upper end also moves accordingly, thereby changing the distance between the left translation plate 820 and the right translation plate 830. In this way, the position of the rotating shaft 210 can be precisely adjusted, thereby constraining the guiding direction of the product.

[0046] Furthermore, such as Figure 1 , 6 As shown in Figure 7, the output mechanism 240 includes a drive belt 250 and an end shaft 260. The end shaft 260 is connected between the ends of the two column plates 230. One end of the drive belt 250 is sleeved on the rotating shaft 210 connected to the input motor 220, and the other end is sleeved on the end shaft 260. Input and output can be realized through a single motor, and the friction of the drive belt 250 is greater than that of the rotating shaft 210, which facilitates providing a reasonable position for applying film to the product.

[0047] Furthermore, such as Figure 7As shown, the lower end of the column plate 230 is further provided with a photoelectric sensor 270, and an open cavity 280 is arranged corresponding to the position of the column plate 230, and the output end of the photoelectric sensor 270 passes through the open cavity 280 and senses the product above. When the product enters the film pasting area, the photoelectric sensor 270 emits from the open cavity 280 to sense the front end of the product, so that the lifting mechanism 300 starts to cover the film, and after the processing is completed, the photoelectric sensor senses the rear end of the product to drive the cutting mechanism 400 to cut and separate the film.

[0048] Further, as shown in Figure 1 、 6 , the flattening mechanism 500 includes a flattening cylinder 510, a support table 520 and a flattening roller 530, the support table 520 is arranged on the gantry 110 and located at the back side of the fixed table 303, the flattening cylinder 510 is arranged on the support table 520, and the driving end thereof is downwardly connected with the flattening roller 530 to drive the flattening roller 530 to move up and down. Through the driving of the flattening cylinder 510, the flattening roller 530 can quickly move up and down, thereby realizing the quick flattening of the film on the product.

[0049] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
