Description

Technical Field

[0001] The utility model belongs to the technical field of tinfoil production, and in particular relates to a colored tinfoil roll spraying device. Background Art

[0002] Tin foil has the advantages of being moisture-proof, anti-oxidation and environmentally friendly. Wrapping food can effectively extend the shelf life of the food. Placing it in the oven can control the baking time and temperature of the food, and prevent the food from being burnt or becoming brittle. During barbecue and baking, the high thermal conductivity of tin foil can help food be baked quickly and prevent the barbecue from absorbing too much grease. With the promotion of street stall economy and barbecue, the use of tin foil is increasing. When tin foil is produced, trademarks or patterns will be sprayed and printed on one side of the tin foil according to demand.

[0003] The commonly used tinfoil spray printing equipment will have a power mechanism at one end of the spraying mechanism to pull the tinfoil forward. Since tinfoil is not water-absorbent, the oil and water contained in the ink are difficult to be absorbed after spraying, making it difficult for the patterns sprayed and printed on the tinfoil to air-dry. These patterns are easily scratched and damaged when they hit the roller, affecting the effect of tinfoil spray printing. Utility Model Content

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] like Figure 1-4 As shown, a colored tinfoil roll spraying device includes a base 1 and an inkjet printer 2. The inkjet printer 2 is arranged on one side of the top of the base 1. An air-drying mechanism 3 is arranged on the other side of the top of the base 1. The air-drying mechanism 3 includes two air-drying drive components 31 for pulling the tinfoil forward and air-drying the ink sprayed on the tinfoil. The two air-drying drive components 31 are fixedly connected to the top of the base 1. A reduction motor 32 is arranged on one side of one of the air-drying drive components 31. A transmission component 33 is arranged between the two air-drying drive components 31. The two air-drying drive components 31 are connected through the transmission component 33.

[0021] According to the above structure, when in use, one of the air-drying drive components 31 is driven to work by the reduction motor 32, and the two air-drying drive components 31 work at the same time through the transmission of the transmission component 33. When the air-drying drive component 31 works, it pulls the tin foil forward, and the tin foil is dried while being transmitted, so as to prevent the ink sprayed on the tin foil from being accidentally scratched.

[0022] like Figure 3 and 4 As shown, the air-drying drive assembly 31 includes two correspondingly arranged support plates 311, and a bottom roller 312 and a hollow roller 313 are rotatably connected between the two support plates 311. The hollow roller 313 is arranged directly above the bottom roller 312, and the side wall of the hollow roller 313 is symmetrically provided with strip grooves 314. One end of the hollow roller 313 and one end of the bottom roller 312 are both provided with gears 318, and the two gears 318 are meshingly connected. The reduction motor 32 is arranged on one side of one of the support plates 311, and the output shaft of the reduction motor 32 is fixedly connected to the other end of the bottom roller 312. One end of the hollow roller 313 is fixedly connected to a pipe shaft 316, and the pipe shaft 316 is rotatably connected to one of the support plates 311 through a bearing, and one end of the pipe shaft 316 is rotatably connected to an air intake pipe 317 through a sealed bearing.

[0023] According to the above structure, before work, one end of the two air inlet pipes 317 is connected to the air outlet of the external hot air blower. During work, the reduction motor 32 drives the bottom roller 312 to rotate. After the transmission of the gear 318, the hollow roller 313 and the bottom roller 312 rotate in the opposite direction, thereby driving the tin foil passing between the bottom roller 312 and the hollow roller 313 to be transmitted forward. When the side wall of the hollow roller 313 cooperates with the side wall of the bottom roller 312 to drive the tin foil, the unprinted part of the tin foil is between the bottom roller 312 and the hollow roller 313, and the distance between the printed parts on the tin foil is equal to the distance between the two strip grooves 314. When the strip grooves 314 on the surface of the hollow roller 313 rotate to the upper surface of the tin foil, the hot air inside the hollow roller 313 is sprayed from the strip grooves 314 to the printed part of the tin foil surface, thereby drying the ink sprayed on the surface of the tin foil.

[0024] like Figure 3 and 4 As shown, the transmission assembly 33 includes two pulleys 331 respectively fixedly mounted on the outer walls of the two tube shafts 316, and the two pulleys 331 are connected by belt transmission. The bisector of the two strip grooves 314 on the side wall of one hollow roller 313 is h1, and the bisector of the two strip grooves 314 on the side wall of the other hollow roller 313 is h2, and h1 and h2 are perpendicular to each other.

[0025] According to the above structure, the strip grooves 314 on the surfaces of the two hollow rollers 313 rotate alternately to the upper surface of the tinfoil. When the strip grooves 314 of one of the hollow rollers 313 rotate to the upper surface of the tinfoil, the other hollow roller 313 cooperates with the corresponding bottom roller 312 to pull the tinfoil forward, and the two air-drying drive components 31 work in sequence to pull the tinfoil forward while air-drying the ink on the surface of the tinfoil.

[0026] like Figure 4 As shown, a C-shaped tile 315 with an opening facing downward is fixedly connected between the two support plates 311 , and the C-shaped tile 315 is arranged on the periphery of the hollow roller 313 .

[0027] According to the above structure, the overflow of hot air from the area other than the upper surface of the tin foil is reduced, thereby improving the air-drying effect.

[0028] The working principle of the utility model is as follows: when in use, one of the air-drying drive components 31 is driven to work by the reduction motor 32, and the two air-drying drive components 31 work at the same time through the transmission of the transmission component 33. When the air-drying drive component 31 works, it pulls the tinfoil forward, and the tinfoil is dried while being driven, so as to prevent the ink sprayed on the tinfoil from being accidentally touched and scratched. Before work, one end of the two air inlet pipes 317 is connected to the air outlet of the external hot air blower. When working, the reduction motor 32 drives the bottom roller 312 to rotate, and through the transmission of the gear 318, the hollow roller 313 rotates in the opposite direction to the bottom roller 312, thereby driving the tinfoil passing through the bottom roller 312 and the hollow roller 313 to be driven forward. When the side wall of the hollow roller 313 cooperates with the side wall of the bottom roller 312 to drive the tinfoil, there is no ink on the tinfoil. The printed part is between the bottom roller 312 and the hollow roller 313. The distance between the printed parts on the tinfoil is equal to the distance between the two strip grooves 314. When the strip grooves 314 on the surface of the hollow roller 313 rotate to the upper surface of the tinfoil, the hot air inside the hollow roller 313 is sprayed from the strip grooves 314 to the printed part of the tinfoil surface, thereby air-drying the ink sprayed on the surface of the tinfoil. The strip grooves 314 on the surfaces of the two hollow rollers 313 rotate alternately to the upper surface of the tinfoil. When the strip grooves 314 of one of the hollow rollers 313 rotate to the upper surface of the tinfoil, the other hollow roller 313 cooperates with the corresponding bottom roller 312 to pull the tinfoil forward. The two air-drying drive components 31 work in sequence to pull the tinfoil forward while air-drying the ink on the surface of the tinfoil.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
