[0002] In the process of product packaging, lamination of sheet-like products (such as capsule aluminum foil sheets, test cards, or test boxes) is a common process. It can effectively protect the contents of sheet-like products from moisture, contamination, or damage, while also improving the overall appearance quality of sheet-like products. However, most existing sheet-like product lamination devices have problems such as complex structure, inconvenient operation, low lamination efficiency, and unsatisfactory heat sealing effect.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a film coating device for plate-shaped products.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The length of the heat-sealing rollers is adapted to the longitudinal height of the packaging film. A flange corresponding to the upper edge of the packaging film is provided at the upper end of the heat-sealing rollers. A heat-sealing strip extending along its generatrix is ​​provided on the heat-sealing rollers. The outer surface of the heat-sealing strip is arc-shaped so as to longitudinally heat-seal the packaging film as the heat-sealing rollers rotate, so that the packaging film forms multiple independent cavities corresponding to the plate-shaped products.

[0013] Preferably, the outer wall of the heat-sealing strip and the outer wall of the flange are located on the same cylindrical surface, and a cutting protrusion is provided in the middle of the heat-sealing strip of one of the heat-sealing rollers, the cutting protrusion extending upward to the flange;

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0029] like Figure 1-3 As shown, a sheet-like product coating device includes a conveying track 3, a support member, and a heat sealing mechanism. The conveying track 3 has a U-shaped opening, and a U-shaped folded packaging film 4 is provided inside the conveying track 3 to serve as a loading station. The front end of the conveying track 3 is provided with a loading mechanism to facilitate the loading of sheet-like products to be coated. The discharge port of the loading mechanism extends to the top of the conveying track 3, and the end of the conveying track 3 extends to the heat sealing mechanism.

[0030] The feeding mechanism is a vibrating feeding plate 1 or a feeding suction cup. The vibrating feeding plate 1 is a conventional commercially available structure and is only used for feeding. No further restrictions are placed on the vibrating feeding plate 1. The bottom of the vibrating feeding plate 1 is equipped with a vibration mechanism, which is a vibration motor. Inside the vibrating feeding plate 1, there is a spirally rising feeding track. The plate-shaped product is spirally raised along the feeding track through vibration.

[0031] Above the vibrating feeding plate 1, there is a horizontally extending feeding channel 2 corresponding to the feeding track. One end of the feeding channel 2 extends to the end of the feeding track of the vibrating feeding plate 1, and the other end extends to the feeding station. The feeding channel 2 has a guide groove corresponding to the plate-shaped product. Specifically, the feeding channel 2 can be a channel steel. The opening of the channel steel is folded inward to form a square inner cavity corresponding to the plate-shaped product as a guide groove.

[0032] Two support members are located at the two ends of the conveyor track 3, and form a U-shaped channel with the interior of the conveyor track 3 corresponding to the packaging film 4, thereby ensuring that the packaging film 4 always maintains an open shape in the conveyor track 3, so as to facilitate the conveying of the plate-shaped product into the packaging film 4.

[0033] The heat sealing mechanism is equipped with a heat sealing channel 9 corresponding to the conveying track 3. An assembly box 5 is provided on the side of the heat sealing channel 9. The side of the assembly box 5 is equipped with a conveying component, a longitudinal heat sealing component, and a transverse heat sealing component that extend into the heat sealing channel 9. Driven by the conveying component, the packaging film 4 is driven on the conveying track 3, so that it moves synchronously after the plate-shaped product is placed in it. With the heat sealing of the longitudinal heat sealing component and the transverse heat sealing component, each plate-shaped product has an independent outer film inside.

[0034] In an optional embodiment, a limiting mechanism is disposed at one end of the feeding channel 2 corresponding to the feeding station, for precise control of the plate-shaped product, so that the plate-shaped product falls into the feeding station in sequence. The limiting mechanism includes a mounting plate, a lever 14, limiting plugs 15 and a driving mechanism. The mounting plate is fixed to the side of the feeding channel 2 away from the opening, and both ends of the mounting plate extend outward to both sides of the feeding channel 2. The lever 14 rotates on the mounting plate in the middle, and two limiting plugs 15 are respectively hinged to both ends of the lever 14. The distance between the two limiting plugs 15 is adapted to the width of the plate-shaped product. The side of the feeding channel 2 is provided with a corresponding insertion port for the two limiting plugs 15. The insertion port extends in the horizontal direction. As the driving mechanism is connected to the lever 14, the two limiting plugs 15 extend into the feeding channel 2 in sequence to stop the plate-shaped product in the feeding channel 2.

[0035] Specifically, the lever 14 drives the upper and lower limit plugs 15 to work together. When the lower limit plug 15 stops the plate-shaped product, no material is fed. When the lower limit plug 15 retracts, the upper limit plug 15 stops one plate-shaped product above it, and only one plate-shaped product between the two falls down, thus ensuring accurate feeding. Furthermore, when the lower limit plug 15 is inserted again, the upper limit plug 15 is pushed out, causing the plate-shaped product to move down one position. The above operation is repeated to ensure that only one plate-shaped product is fed each time.

[0036] In one optional embodiment, the mounting plate is adapted to the feeding channel 2. Specifically, the portions of the mounting plate extending beyond the feeding channel 2 at both ends need to meet the assembly requirements of the limiting plugs 15 and the levers 14. To ensure the feeding accuracy of the plate-shaped product, a set of limiting plugs 15 is provided at each end of the mounting plate to stop the plate-shaped product on both sides of the feeding channel 2. The rotating shafts of the two levers 14 are respectively connected to a stepper motor, and the two stepper motors drive the two levers 14 to ensure that the limiting plugs 15 on both sides are inserted and removed from both sides of the plate-shaped product.

[0037] This application is particularly applicable to aluminum foil plates for capsules or antigen test cards. Specifically, by vibrating the feeding tray 1, the capsule side of the aluminum foil plate is made to open the feeding channel 2. The width of the plate is greater than the thickness of the feeding channel 2. A corresponding groove for the limiting plug 15 is provided on the side of the feeding channel 2, so that the limiting plug 15 can be inserted into the feeding channel 2. Since there is an arc chamfer on the edge of the aluminum foil plate, the sharp end of the limiting plug 15 is inserted between two adjacent aluminum foil plates.

[0038] In an optional embodiment, the conveying component includes two conveying rollers 6 that clamp the upper edge of the packaging film 4. The assembly box 5 is provided with a support arm on the side. The conveying rollers 6 are made of rubber, so as to clamp the packaging film 4 and ensure that the upper edge of the packaging film 4 is pinched for subsequent heat sealing. When the conveying rollers 6 clamp the packaging film 4, they rotate to drive the packaging film 4 to move forward. One of the conveying rollers 6 is connected to a first conveying motor.

[0039] The side of the assembly box 5 is also provided with a support arm for a transverse heat sealer. The transverse heat sealer is located behind the conveyor and is used to heat seal the packaging film 4 that passes through. The transverse heat sealer is used to heat seal the upper edge of the packaging film 4. The transverse heat sealer includes two heat seal plates 7 that clamp the upper edge of the packaging film 4 to heat seal the packaging film 4 that passes through the two heat seal plates 7. One of the heat seal plates 7 is fixed on the connecting plate. The connecting plate is slidably assembled along the packaging film 4 through the guide post. A compression spring is provided at one end of the guide post that passes through the connecting plate to ensure that there is a corresponding compression force between the heat seal plates 7 and the packaging film 4, thereby improving the heat sealing effect. An inclined surface is provided at the end of the heat seal plate 7 near the conveyor to ensure the guidance of the packaging film 4.

[0040] The longitudinal heat-sealing component includes two heat-sealing rollers 8 that clamp the packaging film 4. The side of the assembly box 5 is also provided with a support arm for the longitudinal heat-sealing component. The length of the heat-sealing roller 8 is adapted to the longitudinal height of the packaging film 4, and the circumference of the heat-sealing roller 8 is adapted to the length of the pre-set packaging film 4 after heat sealing. A flange 11 corresponding to the upper edge of the packaging film 4 is provided at the upper end of the heat-sealing roller 8. The flange 11 is annular and its thickness is adapted to the heat-sealing width of the upper edge of the packaging film 4. The flanges 11 on the two heat-sealing rollers 8 are respectively squeezed to the heat-sealing position of the upper edge of the packaging film 4, so as to ensure the driving of the packaging mold. A heat-sealing strip 12 extending along its generatrix is ​​provided on the heat-sealing roller 8. The outer surface of the heat-sealing strip 12 is arc-shaped, and the outer wall of the heat-sealing strip 12 and the outer wall of the flange 11 are on the same cylindrical surface, so as to perform longitudinal heat sealing on the packaging film 4 with the rotation of the heat-sealing roller 8, so that the packaging film 4 forms multiple independent cavities corresponding to the plate-shaped products.

[0041] Both the heat-sealing strip 12 and the heat-sealing plate 7 are electrothermal materials. A brush is provided at the upper end of the heat-sealing roller 8 to keep the circuit open during rotation and ensure that the heat-sealing roller 8 supplies power to the heat-sealing strip 12 during rotation. The distance between the two heat-sealing rollers 8 is greater than the thickness of the plate-shaped product to be protected. Since the outer wall of the heat-sealing strip 12 and the outer wall of the flange 11 are located on the same cylindrical surface, the protective film between the two adjacent plate-shaped products is formed by extrusion during the rotation of the heat-sealing roller 8.

[0042] To facilitate subsequent packaging, a cutting protrusion 13 is provided in the middle of the heat sealing strip 12 of one of the heat sealing rollers 8. The cutting protrusion 13 extends upward along the generatrix of the columnar surface corresponding to the heat sealing strip 12 to the flange 11; a cutting groove corresponding to the cutting protrusion 13 is provided in the middle of the heat sealing strip 12 of the other heat sealing roller 8.

[0043] One of the heat-sealing rollers 8 is connected to a second conveyor motor. A heat insulation layer is provided between the heat-sealing strip 12 and the heat-sealing roller 8. During the rotation of the heat-sealing roller 8, the packaging film 4 is cut by the squeezing of the cutting protrusion 13 and the cutting groove.

[0044] In this embodiment, the bottom of the heat-sealing channel 9 is equipped with a conveyor belt corresponding to the plate-shaped product, thereby conveying the cut packaging film 4 backward. The end of the heat-sealing channel 9 is equipped with a counter 10 corresponding to the plate-shaped product. The counter 10 is an infrared counting module.

[0045] In an optional embodiment, the support member includes support rollers for a U-shaped plate, the U-shaped plate being adapted to the U-shaped inner cavity formed by folding the packaging film 4, and support rollers being rotatably connected to the bottom and sides of the U-shaped plate respectively. The distance between the support rollers and the inner wall of the conveyor track 3 is adapted to the packaging film 4, and the upper end of the support member extends out of the conveyor track 3 and folds to both sides, and then the folded part is fixed to both sides of the conveyor track 3 by bolts.

[0046] The bottom and sides of the U-shaped plate are provided with corresponding support roller slots, which are used to rotate and connect the support rollers.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
