Description

Technical Field

[0001] This utility model relates to the field of co-extruded film surface treatment technology, specifically to a surface treatment device for an antibacterial multilayer co-extruded film. Background Technology

[0002] Antibacterial multilayer co-extruded film is a specially designed plastic film with the ability to inhibit or kill surface microorganisms, such as bacteria and mold. It achieves this function by integrating antibacterial agents into the film structure. This film is made by compounding multiple layers of different polymer materials in one step through a co-extrusion process.

[0003] Existing multilayer co-extruded films produce low molecular weight precipitates during extrusion, such as slip agents and opening agents. These precipitates form a weak interfacial layer, which seriously affects the corona treatment effect, printing adhesion, composite strength, heat sealing strength, and the effectiveness of antibacterial function, thus impacting subsequent practical use. Utility Model Content

[0004] The purpose of this invention is to provide a surface treatment device for antibacterial multilayer co-extruded film, so as to solve the problem mentioned in the background art that the precipitates generated during the extrusion of multilayer co-extruded film will affect subsequent use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a surface treatment device for an antibacterial multilayer co-extruded film, comprising a treatment box, wherein inlet and outlet slots are symmetrically arranged at both ends of the treatment box and the inlet and outlet slots communicate with the interior of the treatment box;

[0006] Also includes:

[0007] A fixing frame is installed inside the processing box, and two sets of fixing frames are respectively located on both sides of the inside of the processing box. Adsorption rollers are installed inside the processing box, and two sets of adsorption rollers are respectively located on the upper and lower sides between the two fixing frames. Adsorption holes are provided on the surface of the adsorption rollers, and a number of adsorption holes are provided and evenly distributed on the surface of the adsorption rollers. The adsorption holes are connected to the inside of the adsorption rollers. One end of the adsorption roller is connected to a suction tube, and one end of the suction tube is provided with two sets of suction nozzles, which are respectively connected to one end of the two adsorption rollers. A first fan is installed at the upper end of the processing box, and the other end of the suction tube is connected to the first fan.

[0008] Preferably, the adsorption roller is provided with connecting rings at both ends, and the circular hole on the surface of the connecting ring near the suction tube is connected to the inside of the adsorption roller. The fixing frame and the adsorption roller are connected by a first bearing, and the connecting ring is movably engaged in the inner hole of the first bearing.

[0009] Preferably, the suction tube has a connector at the nozzle, the connector is connected to the connecting ring via a second bearing, the connector is inserted into the inner hole of the second bearing, and the second bearing is inserted into the connecting ring at the corresponding position, and a shielding plate is provided between the connector and the suction tube.

[0010] Preferably, a connecting pipe is installed inside the processing box. The connecting pipe has a U-shaped structure and is located on one side of the adsorption roller. A nozzle is provided on the inner surface of the connecting pipe. Several nozzles are provided and evenly distributed on the inner surface of the connecting pipe. The nozzle outlets are inclined towards the adsorption roller. A second fan is provided on the outside of the processing box and is connected to one end of the connecting pipe.

[0011] Preferably, the processing box is equipped with a support frame inside, and two sets of the support frame are symmetrically arranged and located inside the two inlet and outlet slots respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) Two sets of adsorption rollers are set up. The adsorption rollers are connected to the same suction pipe, and the other end of the suction pipe is connected to the first blower. The multilayer co-extruded film enters the processing chamber from the inlet and outlet groove at one end, passes between the two sets of adsorption rollers, and then moves out from the inlet and outlet groove at the other end. The supply film is wound up by the winding mechanism. When the co-extruded film moves, the adsorption roller rotates on the surface of the co-extruded film. The first blower generates negative pressure and directly removes the precipitate powder from the surface of the co-extruded film by the porous structure on the surface of the adsorption roller. The other end of the first blower is connected to an external collection device to extract the precipitate powder to the collection device for unified collection and processing.

[0015] (2) By setting a blower mechanism behind the two sets of adsorption rollers, the second blower is a mechanism for blowing air into the processing box. External air is blown out through the nozzle to the surface of the co-extruded film, and the residual loose precipitates on the surface are blown up, which is convenient for the adsorption rollers to pick up. Thus, the precipitates that are not picked up in time are blown away from the surface of the co-extruded film, thereby improving the cleanliness of the surface of the co-extruded film.

The device includes a treatment chamber 1, with inlet and outlet slots 2 symmetrically arranged at both ends of the treatment chamber 1, and the inlet and outlet slots 2 communicating with the interior of the treatment chamber 1. This invention primarily addresses the problem that precipitates generated during the extrusion of multilayer co-extruded films can affect subsequent use.

[0023] For the device provided by this utility model, please refer to Figure 1-4 The following is a detailed introduction.

[0024] A fixing frame 5 is installed inside the processing box 1, and two sets of fixing frames 5 are respectively located on both sides of the inside of the processing box 1. An adsorption roller 10 is installed inside the processing box 1. Two sets of adsorption roller 10 are respectively located on the upper and lower sides between the two fixing frames 5. Adsorption holes 11 are provided on the surface of the adsorption roller 10. Several adsorption holes 11 are provided and evenly distributed on the surface of the adsorption roller 10. The adsorption holes 11 are connected to the inside of the adsorption roller 10. One end of the adsorption roller 10 is connected to a suction pipe 13. One end of the suction pipe 13 is provided with two sets of suction nozzles and is respectively connected to one end of the two adsorption rollers 10. A first fan 3 is installed at the upper end of the processing box 1, and the other end of the suction pipe 13 is connected to the first fan 3.

[0025] Please see Figure 2To further explain, a connecting pipe 8 is installed inside the processing box 1. The connecting pipe 8 has a U-shaped structure and is located on one side of the adsorption roller 10. A nozzle 9 is provided on the inner surface of the connecting pipe 8. Several nozzles 9 are provided and evenly distributed on the inner surface of the connecting pipe 8. The nozzle outlets of the nozzles 9 are inclined towards the adsorption roller 10. A second fan 4 is provided on the outside of the processing box 1 and is connected to one end of the connecting pipe 8. The second fan 4 is a mechanism for blowing air into the processing box 1. It is designed with a blowing mechanism to blow external air through the nozzles 9 to the surface of the co-extruded film, blowing away the residual loose precipitates on the surface, which are then easily absorbed by the adsorption roller 10.

[0026] Please see Figure 4 To further explain, the adsorption roller 10 has connecting rings 16 at both ends, and the circular hole on the surface of the connecting ring 16 near the suction tube 13 communicates with the interior of the adsorption roller 10. The fixing frame 5 is connected to the adsorption roller 10 through a first bearing 17, and the connecting ring 16 is movably engaged in the inner hole of the first bearing 17. The first bearing 17 is set to connect the adsorption roller 10 and the fixing frame 5, thereby enabling the adsorption roller 10 to rotate.

At the same time, the shielding plate 14 can shield the outside of the second bearing 18, so that air will not escape from the gap of the second bearing 18 during suction.

[0027] Please see Figure 3 To further explain, heating rods 12 are symmetrically arranged on both sides of the inner wall of the processing box 1, and several heating rods 12 are arranged and evenly distributed on the inner wall surface of the processing box 1, so that the internal temperature of the processing box 1 is raised to 60℃-80℃. This temperature is lower than the softening point of the co-extruded film, allowing the slip agent / opening agent inside to have more time to diffuse evenly into the interior, reducing surface enrichment caused by rapid cooling of the surface layer.

[0028] Please see Figure 3 To further explain, the processing box 1 is equipped with a bracket 6, and two sets of brackets 6 are symmetrically arranged and located on the inner side of the two inlet and outlet slots 2 respectively.
