Description

Technical Field

[0001] The present invention relates to a food machine, in particular to a candy film coating device. Background Art

[0002] Coating candies is an effective means of ensuring the hygiene and safety of candies and extending their shelf life. In the production process of many types of candies, candies need to be wrapped with candy packaging film, forming the candy packaging film into a bag to wrap the candies. To further ensure the shelf life of the candies, a shrinking process is added after the candy packaging is finalized. The candy packaging film is heated and shrunk so that it fits the candy packaging film around the candy. This prevents the candy from coming into contact with air, thereby improving the shelf life. However, the bag-shaped candy packaging film formed during the candy production coating process is naturally filled with air. During the heating and shrinking process, the air in the bag-shaped candy packaging film is difficult to expel, making it difficult to isolate the candy from air, and thus failing to achieve the ideal coating effect. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a candy perforation and film coating device, which can not only conveniently coat the candy, but also facilitate the subsequent film shrinking process to discharge the air inside the film.

[0004] In order to solve the above technical problems, the present invention provides a candy perforation and coating device, including a film roll mounting shaft, a plurality of film feed guide rollers, and a film coating device. A perforation roller is provided in the film feeding path formed by the plurality of film feed guide rollers, and a perforation needle is provided on the periphery of the perforation roller; the film coating device is located at the end of the film feeding path, a film guide inclined plate is provided at the front end of the film coating device, and a film coating sealing and cutting assembly is provided below the discharge end of the film coating device.

[0005] In the above structure, since a perforated roller is provided in the film feeding path formed by the plurality of film feeding guide rollers, and a perforated needle is provided on the periphery of the perforated roller, the candy packaging film used to wrap the candy will bypass the perforated roller during the process of being conveyed to the film wrapper, and the perforated needle provided on the periphery of the perforated roller will pierce a small hole in the candy packaging film at intervals. The distance between adjacent small holes will correspond to the length of the candy to be wrapped, and the position of the small hole is in the middle of adjacent candies. In this way, in the subsequent shrinking process, the air in the bag-shaped candy packaging film during the heating and shrinking process of the candy packaging film can be discharged through the small holes, and the candy packaging film can be well fitted with the candy to be packaged and isolated from the air. After the shrinking is completed, the two ends of the candy will be heated and fused to seal, and the excess packaging film at both ends of the candy will be cut off. The position of the small hole is located at the cut-off part, and there is no possibility of air leakage for the wrapped candy.

[0006] Since the film wrapper is located at the end of the film feeding path, a film guide inclined plate is provided at the front end of the film wrapper, and a film sealing and cutting assembly is provided below the discharge end of the film wrapper, the perforated candy packaging film enters the film wrapper under the guidance of the film guide inclined plate, and its two sides are folded toward the lower middle part in the film wrapper to form a bag shape, wrapping the candy entering the film wrapper, and the two sides of the candy packaging film are led out from the film sealing lead-out groove in the lower middle part of the film wrapper, and are heat-sealed and the excess part is cut off by the film sealing and cutting assembly provided below the discharge end of the film wrapper, thereby conveniently realizing the film wrapping process of the candy, and the small holes punched in the candy packaging film enable the subsequent shrinking process to smoothly discharge the air in the film.

[0007] In a preferred embodiment of the present invention, the perforating needle is located in the middle of the perforating roller in the width direction. This embodiment ensures that the small holes perforated in the candy packaging film remain within the bag-shaped packaging film formed by the film wrapper and are not cut away by the film sealing and cutting assembly.

[0008] In another preferred embodiment of the present invention, the film guide ramp is mounted at the front end of the film wrapper base. Side panels are mounted on either side of the film wrapper base. The lower edges of the side panels are provided with inwardly facing lower hems. The lower hems of the side panels, together with the lower side of the film wrapper base, form a film wrapping channel. The distance between the lower hems of the side panels defines a film sealing outlet slot. With this embodiment, the film guide ramp mounted at the front end of the film wrapper base allows the candy packaging film to smoothly enter the film wrapping channel. After wrapping the candy conveyed into the film wrapping channel, the excess film on either side is drawn out through the film sealing outlet slot in the lower center portion of the film wrapper, thereby completing the candy wrapping process.

[0009] In another preferred embodiment of the present invention, an upper folding edge facing outward is provided on the upper edge of the side panel. By adopting this embodiment, the side panel can be strengthened and its rigidity can be improved.

[0010] In a further preferred embodiment of the present invention, a brush is positioned above the coating device and extends between the two side plates behind the coating device base. This embodiment allows the brush to apply gentle pressure to the coated candy, maintaining it at the bottom of the coating channel and maintaining a stable coating state.

[0011] In another preferred embodiment of the present invention, the film-sealing and cutting assembly includes a film-drawing wheel and a sealing and cutting disc mounted on a sealing and cutting wheel shaft. The sealing and cutting disc is fixedly connected to an electric heating element located within the inner cavity of the film-drawing wheel. The sealing and cutting wheel shaft is rotatably supported on a frame, and a sealing and cutting counter-roller is provided on the outer periphery of the sealing and cutting disc. In this embodiment, the film-drawing wheel of the film-sealing and cutting assembly can pull the excess portions of the candy packaging film that are drawn out of the film-drawing notch in the lower middle portion of the film-drawing device after wrapping, maintaining the excess portions of the candy packaging film toward the output end of the film-drawing device. The sealing and cutting disc of the film-sealing and cutting assembly then heats and seals the excess portions of the candy packaging film that are drawn out of the film-drawing notch via the sealing and cutting counter-roller, fusing the two sides together and separating the excess portions, thereby sealing and cutting the candy film.

[0012] In a further preferred embodiment of the present invention, the film sealing and cutting assemblies are arranged in pairs, with one cutting wheel shaft rotatably supported on a cutting shaft seat via an eccentric sleeve, and the other cutting wheel shaft rotatably supported on the cutting shaft seat, which is fixedly connected to the frame. With this embodiment, the paired film sealing and cutting assemblies can more conveniently seal and cut candy packaging film. Furthermore, the eccentric sleeve on one cutting wheel shaft can be used to adjust the spacing between the two film sealing and cutting assemblies to accommodate the sealing and cutting requirements of different candy packaging film thicknesses and materials, ensuring optimal operating conditions.

[0013] In a further preferred embodiment of the present invention, film-drawing teeth are provided on the outer circumference of the film-drawing wheel, and the film-drawing teeth of the two film-drawing wheels mesh with each other. With this embodiment, the film-drawing wheels use the meshing film-drawing teeth to clamp and pull the excess portion of the candy packaging film on both sides of the candy packaging film drawn out from the film-drawing notch, resulting in a stable film-drawing effect.

[0014] In another further preferred embodiment of the present invention, the outer peripheral sealing and cutting rollers of the sealing and cutting disks have an arc-shaped cross-section, and the opposing points of the sealing and cutting rollers in the two film sealing and cutting assemblies are located below the film sealing outlet slot. With this embodiment, the opposing points of the sealing and cutting rollers in the two film sealing and cutting assemblies can achieve point-like contact at the sealing and cutting locations on both sides of the candy packaging film, completing the sealing and cutting of the candy packaging film during the rotation of the two sealing and cutting disks, resulting in excellent performance. The opposing points of the sealing and cutting rollers in the two film sealing and cutting assemblies are located below the film sealing outlet slot, ensuring that the candy packaging film is sealed and cut immediately after being drawn out of the film sealing outlet slot.
