Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and in particular to an automatic steam shrinking machine. Background Art

[0002] The steam shrink machine uses the constant temperature and uniform temperature distribution of steam to work, which makes its effect surpass that of ordinary electric infrared heating shrink machines. Steam shrink machines are widely used in the food and beverage industry such as barrels or small bottles of mineral water, purified water, soda and tea beverages, as well as cosmetics, shampoo and hardware electronics that require shrink film packaging.

[0003] The steam shrinking machine in the related art generally includes a chassis, a conveyor belt and a steam nozzle. The conveyor belt transports the product through the chassis, and the product is pre-covered with a shrink film, and text and pattern information are printed on the surface of the shrink film. Multiple steam nozzles are installed in the chassis, and the heater outside the chassis heats water to generate steam. The steam is ejected from the steam nozzle through the pipe, so that the shrink film shrinks when heated and adheres closely to the surface of the product, thereby realizing the packaging of the product.

[0004] However, some products have different cross-sectional areas at different heights, so the shrink film needs different shrinkage amounts at different heights. In the related art, steam is ejected from the steam nozzle, so that different areas of the shrink film shrink at the same time, which easily leads to wrinkles on the surface of the product. In addition, since different areas of the shrink film shrink at the same time, the shrink film lacks positioning, which easily leads to the shrink film being offset when shrinking. Summary of the invention

[0005] In order to improve the situation where wrinkles and deviations occur in shrink films, the present application provides an automatic steam shrinking machine.

[0006] The present application provides an automatic steam shrinking machine, which adopts the following technical solution: An automatic steam shrinking machine, comprising: frame; A chassis connected to the rack; A transport assembly, the transport assembly is connected to the frame, and the transport assembly drives the product through the chassis; A mobile component, wherein the mobile component is disposed in the chassis; A steam outlet component is connected to the moving component, the steam outlet component comprises a steam ring, the steam ring is sleeved on the circumference of the product, the steam ring is provided with a steam outlet hole, and the steam is sprayed toward the shrink film from the steam outlet hole; the moving component drives the steam ring to move from one end of the product to the other end.

[0007] By adopting the above technical solution, the transport component transports the product into the chassis, and the moving component drives the steam outlet component to move from one end of the product to the other end, so that the steam ring gradually sprays steam from one end of the product to the other end, thereby gradually shrinking the shrink film on the product, which can reduce the shrink film from wrinkling on the product surface. In addition, shrinking one end of the shrink film first can fix the position of the shrink film, which can reduce the shrink film from deviating during the subsequent shrinking process.

[0008] Optionally, the chassis is provided with a guide ring groove, and a plurality of the steam outlet components are provided, and the moving component drives the steam outlet component to move in a circular motion along the guide ring groove, so that the steam outlet component moves with the product.

[0009] By adopting the above technical solution, the moving component enables multiple steam guide components to move cyclically along the guide ring groove, so that the steam outlet component can move with the product. The steam outlet component can also move from one end of the product to the other end while moving with the product, so that the shrink film can be shrunk to the product surface while the product keeps moving, thereby improving processing efficiency.

The steam ring and the rotating member can rotate relative to each other, so that the steam ring can remain horizontal under the action of its own gravity, improving the coaxiality of the steam ring and the product, which is conducive to the steam ring being sleeved around the product and outputting a uniform amount of steam to the product.

[0018] Optionally, the moving assembly further comprises a connecting block, and the connecting block is respectively connected to the rotating member and the supporting belt body.

The inclined section of the support belt body 52 is adapted to the inclined steam flow section 311. The moving component 5 drives the steam outlet component 6 to move, so that the steam ring 61 moves with the product 100. When the steam ring 61 passes through the inclined section of the support belt body 52, the support belt body 52 drives the steam ring 61 to move from one end of the product 100 to the other end, thereby gradually spraying steam from one end of the product 100 to the other end, so that the shrink film 200 is more closely attached to the surface of the product 100.

The sealing film 64 is located on the inner side of the chassis 3, and the sealing film 64 blocks the guide ring groove 31, so that the steam flow section 311 of the guide ring groove 31 forms a cavity structure. When the moving component 5 drives the steam ring 61 to pass through the steam flow section 311, the sealing film 64 can reduce the leakage of steam in the steam flow section 311, which is conducive to the steam entering the steam ring 61 and improving the utilization rate of the steam.

[0044] Embodiment 3: Embodiment 3 of the present application provides an automatic steam shrinking machine. The difference between Embodiment 3 of the present application and Embodiment 2 is that: refer to Figure 6 The sealing film 64 is annular, and the shape of the sealing film 64 matches the shape of the guide ring groove 31. The sealing film 64 is slidably connected to the guide ring groove 31, and the sealing film 64 blocks the guide ring groove 31, so that the steam circulation section 311 forms a cavity structure. The sealing film 64 is provided with through holes, and the through holes of the sealing film 64 are respectively connected with the steam circulation section 311 and the circulation cavity of the steam ring 61. The steam in the steam circulation section 311 passes through the through holes of the sealing film 64 and the circulation cavity and then sprays out from the steam outlet of the steam ring 61. The sealing film 64 contacts the blocking strip 4 in the steam-free section 312, thereby reducing the steam from entering the steam-free section 312, so that the steam is more concentrated in the steam circulation section 311.
