Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric composite machines, in particular to a multi-layer non-woven fabric composite device. Background Art

[0002] The multi-layer non-woven fabric composite device is a device used for hot pressing and laminating multi-layer non-woven fabrics. It is usually composed of rollers, a heating system, a pressure system, etc. Due to its high production efficiency, it is widely used in non-woven fabric production enterprises.

[0003] The multi-layer non-woven fabric composite device in the prior art conveys the multi-layer non-woven fabric material to the composite area through the conveying mechanism when working. The composite area is usually composed of a hot pressing roller and a rubber-coated roller. The hot pressing roller is heated to a suitable temperature to heat the multi-layer non-woven fabric so that the non-woven fabric material rotates between the hot pressing roller and the rubber-coated roller to apply pressure, so that the multi-layer non-woven fabric is tightly bonded together, thereby completing the composite of the multi-layer non-woven fabric.

[0004] During the hot pressing process of the multi-layer non-woven fabric in the existing multi-layer non-woven fabric composite device, due to the relatively high temperature of the surface of the hot pressing roller, when the hot pressing roller contacts the multi-layer non-woven fabric, part of the fiber filaments on the surface of the non-woven fabric will adhere to the surface of the hot pressing roller. The fiber filaments on the surface of the hot pressing roller will melt for a long time and easily stick to the surface of the hot pressing roller. The operator needs to regularly clean the residual molten fiber filaments on the surface of the hot pressing roller, and the cleaning is relatively troublesome, so there are shortcomings. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a multi-layer non-woven fabric composite device, which is used to solve the problem that the melted fiber filaments on the surface of the hot pressing roller in the existing multi-layer non-woven fabric composite device are easily adhered to the surface of the hot pressing roller and are relatively troublesome to clean.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A multi-layer non-woven fabric composite device comprises a hot pressing roller and a rubber-coated roller which are arranged one above the other inside a machine body, and a conveying roller and a winding roller which are respectively arranged upstream and downstream of the machine body; a fixing frame corresponding to the hot pressing roller is horizontally arranged on one side of the machine body close to the conveying roller; a negative pressure groove which corresponds to the hot pressing roller and is connected to an industrial vacuum cleaner is movably mounted on the fixing frame; a scraper which contacts the surface of the hot pressing roller is fixedly connected between the hot pressing roller and the fixing frame and is located at the bottom of the negative pressure groove.

[0008] Preferably, the negative pressure groove is in a structure with the tops of the negative pressure grooves corresponding to the hot pressing roller close to each other and the bottoms far away from each other.

[0009] Preferably, the distance between the top of the negative pressure groove corresponding to one side of the hot pressure roller and the hot pressure roller does not exceed CM.

[0010] Preferably, the fixing frame and the negative pressure tank as well as the negative pressure tank and the scraper are fixedly connected by bolts.

[0011] Preferably, the scraper is provided with an adjustment groove corresponding to the bolt for laterally adjusting the distance from the hot pressing roller.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model provides a negative pressure groove and a scraper. When the hot pressing roller and the rubber-coated roller are rotating to hot-press the multi-layer non-woven fabric, the scraper intercepts and scrapes the fiber filaments attached to the surface of the hot pressing roller. The scraped loose fiber filaments are adsorbed and collected by the negative pressure groove connected to the industrial vacuum cleaner, thereby reducing the adhesion of the fiber filaments on the surface of the hot pressing roller, eliminating the need for frequent manual cleaning, and reducing labor intensity. The utility model solves the problem that the molten fiber filaments on the surface of the hot pressing roller in the existing multi-layer non-woven fabric composite device are easily adhered to the surface of the hot pressing roller, which is relatively troublesome to clean.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3As shown, the utility model provides a technical solution: a multi-layer non-woven fabric composite device, comprising a hot pressing roller 101 and a rubber-coated roller 102 arranged one above and one below inside a machine body 1, and a conveying roller 103 and a winding roller 104 respectively arranged upstream and downstream of the machine body 1, a fixing frame 2 corresponding to the hot pressing roller 101 is horizontally arranged on one side of the machine body 1 close to the conveying roller 103, and a negative pressure tank 3 corresponding to the hot pressing roller 101 and connected to an industrial vacuum cleaner is movably installed on the fixing frame 2;

[0020] The negative pressure groove 3 on the side corresponding to the hot pressing roller 101 is in a structure with the top close to the bottom and far away from the top, which is convenient for air circulation and improves the suction force of the negative pressure groove 3 on the non-woven fiber filaments intercepted by the scraper 4. The distance between the top of the side corresponding to the hot pressing roller 101 of the negative pressure groove 3 and the hot pressing roller 101 does not exceed 1CM;

[0021] A scraper 4 in contact with the surface of the hot pressure roller 101 is fixedly connected between the hot pressure roller 101 and the fixed frame 2 and located at the bottom of the negative pressure groove 3. The fixed frame 2 and the negative pressure groove 3 as well as the negative pressure groove 3 and the scraper 4 are fixedly connected by bolts. The scraper 4 is provided with an adjustment groove 401 corresponding to the bolt for laterally adjusting the distance from the hot pressure roller 101.

[0022] Working principle: The multi-layer non-woven fabric is conveyed by the conveying roller 103 and the winding roller 104, so that the hot pressing roller 101 and the rubber-coated roller 102 perform hot pressing and compounding on the non-woven fabric. When the hot pressing roller 101 rotates, the scraper 4 contacts the surface of the hot pressing roller 101 to intercept and scrape the non-woven fabric fiber filaments on the surface of the hot pressing roller 101. The non-woven fabric fiber filaments that are scraped loose are adsorbed and collected by the negative pressure tank 3 connected to the industrial vacuum cleaner, thereby completing the cleaning of the non-woven fabric fiber filaments and reducing the non-woven fabric fiber filaments sticking to the surface of the hot pressing roller 101. The operator does not need to clean frequently, which reduces the labor intensity.
