Novel steam spray pipe capable of achieving rapid and efficient film packaging

Abstract

The invention discloses a novel steam spray pipe capable of achieving rapid and efficient film packaging. The novel steam spray pipe comprises a vertical steam supply pipe. The steam outlet end of the steam supply pipe is connected with two hollow communicating pipes which are oppositely arranged and communicate with the steam supply pipe. The included angle ranging from 120 degrees to 135 degrees is formed between each communicating plate and the steam supply pipe. Hollow spray plates which are horizontally arranged are connected to the bottom ends of the communicating plates. One ends of the spray plates communicate with the communicating plates. The other ends of the spray plates are opened, and the spray plates are located between the two communicating plates and hinged to the communicating plates. The steam spray pipe can solve the problems that an existing steam spray pipe is uneven in jetting, and bubbles, wrinkles and the like happen to films. The communicating plates are arranged and then connected with the spray plates, and therefore the steam jetting area is increased; and compared with previous hole jetting, strip-shaped jetting is adopted in the novel steam spray pipe, the area between the novel steam spray pipe and the films is increased, and the film packaging quality is improved.

Description

technical field [0001] The invention relates to a packaging device, in particular to a novel steam spray tube capable of fast and efficient film packaging. Background technique [0002] After the bottled water is filled with water and sealed, it is necessary to pack a cover-like film on the mouth of the barrel so that the film can wrap the mouth of the barrel to avoid contamination of the mouth of the barrel, so that when people need to put the bottled water When installed on a water dispenser, tearing off the film on the mouth of the barrel can ensure that the mouth of the barrel will not be polluted when drinking; traditional film packaging uses hot air, but it has the following disadvantages: small thermal inertia, large temperature changes, The shrinkage of the film is uneven, and it is prone to "wrinkle" and "bubble", especially for plastic bottles; in addition, because the hot air is heated by an electric heating tube, the power consumption is large and the operating c...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing steam nozzle cannot heat the film evenly, and because it is arranged on both sides of the conveyor belt, when the steam reaches the packaging film, it has already dissipated part of the heat, resulting in uneven heat distribution. The coating has a certain influence, and the purpose is to provide a new type of steam nozzle for fast and efficient film packaging, which can make the steam spray evenly cover the mouth of the bucket, thereby improving the efficiency and quality of the coating
