Description
Technical Field
The utility model belongs to the technical field of film production, and particularly relates to an online lip-hanging and sucking device for BOPP film production.
Background
Biaxially oriented polypropylene film BOPP is generally a multilayer coextrusion film, and is prepared by coextrusion casting polypropylene particles to form a sheet, and then stretching in longitudinal and transverse directions. In the production process of the BOPP film, polypropylene melt is extruded from a lip of a film head, then is cast on the roller surface of a rotating chilled roller, and is cooled by the chilled roller and a cooling water tank to prepare a sheet. When the melt is extruded from the film head, some low-molecular substances in the melt can be precipitated at the lip of the die head to form hanging lips, and the hanging lips of the lip of the die head, which are condensed at one side of the chill roll, can be more due to the small space between the lip of the die head and the chill roll, narrow space and the requirement of the production process due to the specificity of the additive used in the melt at one side of the chill roll. During production, the hanging lips can fall off and are clamped between a melt and a chilling roller, the hanging lips are embedded into a sheet in the process of casting the sheet to the chilling roller, the sheet embedded with the hanging lips can break due to concentrated tensile stress during stretching, the production continuity is affected, and the machine is stopped when serious; although the smaller hanging lip does not necessarily cause production interruption, the appearance of the film can be blemished due to the hanging lip, and the quality of the product is affected.
Therefore, the application provides an online lip-hanging and sucking device for BOPP film production.
Disclosure of utility model
The utility model aims to provide an online lip-hanging and sucking device for BOPP film production, which can suck lip-hanging objects on a film head lip in the film production process.
In order to solve the technical problems, the utility model adopts the following technical scheme:
an online lip-hanging and sucking device for BOPP film production comprises a suction head, a conduit, a filter and a vacuum pump,
The guide pipe is a hollow pipe with openings at two ends, the two ends of the guide pipe are connected with the vacuum pump through a hose, and a filter is arranged between the vacuum pump and the guide pipe;
The suction heads are sleeved on one side of the guide pipe and are communicated with the guide pipe, a plurality of suction heads are arranged, and the suction heads are arranged in series through the guide pipe to form a row.
Further, the suction head is an aluminum 3D printing profile.
Further, the guide pipe includes a middle pipe and both end pipes, the both end pipes are disposed at both ends of the middle pipe, and the diameter of the both end pipes is larger than that of the middle pipe.
Further, the suction head comprises a suction head opening and a channel, the channel is connected with the guide pipe, the suction head opening is arranged at the front end of the channel, and the suction head opening is arranged obliquely upwards.
The working principle of the utility model is as follows:
When the utility model is used, the suction head opening arranged at one side of the die head lip close to the cold roller faces the die head lip, the distance between the suction head opening and the die head lip is 0.5-1.0mm, and then the vacuum pump is started to adsorb the melt precipitate hanging lip at the die head lip.
Compared with the prior art, the utility model has at least the following beneficial effects:
A cleaning and sucking mechanism is arranged on one side of the lip of the die head, which is close to the cold roller, and a plurality of lip hanging suction heads are matched with a vacuum pump to adsorb and treat the melt precipitate hanging lips of the lip of the die head, so that the precipitate hanging lips of the lip of the die head can be timely cleaned and sucked off by the vacuum pump under the negative pressure of the suction heads, operators do not need to perform manual adsorption continuously, and the safety risk of the operators is reduced while the production efficiency and the quality of finished products are improved.
