Technical Field

[0001] The utility model relates to the technical field of fabric production, in particular to a melt - blowing device for non - woven fabrics. Background Art

[0002] Non - woven fabrics have the characteristics of moisture - proof, breathable, flexible, recyclable, etc., and can be used in different industries, such as masks, clothing, medical use, filling materials, etc. Non - woven fabrics are mostly made of polypropylene pellets as raw materials and are produced by a continuous one - step method of high - temperature melting, spinning, laying, hot - pressing and coiling. A melt - blowing device is required in the production process of non - woven fabrics.

[0003] After the melt - blowing device releases the melt - blown material onto the non - woven fabric, the melt - blown material is easily adhered to the bottom end of the nozzle on the melt - blowing device. As the number of melt - blowing times increases, the melt - blown material adhered to the bottom end of the nozzle gradually increases, thus affecting the release of the melt - blown material by the nozzle. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the melt - blown material adhered to the bottom end of the nozzle in the prior art gradually increases, thus affecting the release of the melt - blown material by the nozzle, and to propose a melt - blowing device for non - woven fabrics.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Design a melt - blowing device for non - woven fabrics, including a support frame. A belt conveyor is connected to the support frame. Fixed plates are fixedly connected to both sides of the support frame. A melt - blowing mechanism is fixedly connected between the two fixed plates. A plurality of nozzles are communicated with the bottom end of the melt - blowing mechanism. A wiping mechanism for cleaning the nozzles is connected to the fixed plate.

[0007] The wiping mechanism includes a mounting plate. The mounting plate is fixedly connected to the fixed plate. An electric telescopic rod is fixedly connected to the mounting plate. A movable frame is fixedly connected to the telescopic end of the electric telescopic rod. A rotating roller is rotatably connected to the movable frame. A cleaning sleeve is sleeved on the rotating roller. The cleaning sleeve is in contact with the nozzle.

[0008] Preferably, an anti - corrosion layer is sprayed on the support frame.

[0009] Preferably, a guide rod is fixedly connected to the mounting plate. The guide rod passes through the movable frame.

[0010] Preferably, a collection mechanism is connected to the movable frame. The collection mechanism includes two symmetrically arranged connecting plates, the two symmetrically arranged connecting plates are fixedly connected to the movable frame, a collection frame is fixedly connected between the two symmetrically arranged connecting plates, the collection frame is located below the cleaning sleeve, a scraping plate is fixedly connected to the collection frame, and the scraping plate is in contact with the cleaning sleeve.

[0012] Preferably, through holes are formed at the bottom end of the collection frame, a collection box is clamped at the bottom end of the collection frame, and the collection box communicates with the through holes.

[0013] A meltblown device for non-woven fabrics proposed by the present utility model has the beneficial effects that:

[0014] After the meltblowing of the non-woven fabric is completed, the electric telescopic rod is activated to drive the movable frame to move a set distance and then reset. The movable frame drives the rotating roller to move, and the rotating roller rolls and contacts the bottom end of the nozzle through the cleaning sleeve to clean the bottom end of the nozzle, preventing the meltblown material from sticking to the bottom end of the nozzle, so as not to affect the release of the meltblown material by the nozzle.

Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Embodiment 1: Refer to Figures 1-3 , a meltblown device for non-woven fabrics, including a support frame 1, an anti-corrosion layer is sprayed on the support frame 1, a belt conveyor 2 is connected to the support frame 1, fixing plates 3 are fixedly connected to both sides of the support frame 1, a meltblown mechanism 4 is fixedly connected between the two fixing plates 3, a plurality of nozzles 5 are communicated with the bottom end of the meltblown mechanism 4, and a wiping mechanism 6 for cleaning the nozzles 5 is connected to the fixing plate 3;

[0022] The wiping mechanism 6 includes a mounting plate 61, the mounting plate 61 is fixedly connected to the fixing plate 3, an electric telescopic rod 62 is fixedly connected to the mounting plate 61, a movable frame 63 is fixedly connected to the telescopic end of the electric telescopic rod 62, a rotating roller 64 is rotatably connected to the movable frame 63, a cleaning sleeve 65 is sleeved on the rotating roller 64, the cleaning sleeve 65 is in contact with the nozzle 5, and a guide rod 66 is fixedly connected to the mounting plate 61, and the guide rod 66 passes through the movable frame 63.

[0023] Working process:

[0024] The non-woven fabric moves along with the belt conveyor 2. When the non-woven fabric passes through the meltblown mechanism 4, the meltblown mechanism 5 releases the meltblown material through the nozzles 5 to perform meltblown treatment on the non-woven fabric. After the meltblown of the non-woven fabric is completed, the electric telescopic rod 62 is started to drive the movable frame 63 to move a set distance and then reset. The movable frame 63 drives the rotating roller 64 to move. The rotating roller 64 rolls in contact with the bottom end of the nozzle 5 through the cleaning sleeve 65 to clean the bottom end of the nozzle 5, avoiding the adhesion of the meltblown material to the bottom end of the nozzle 5, so as not to affect the release of the meltblown material by the nozzle 5.

[0025] Embodiment 2: Refer to Figures 3-4, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that a collection mechanism 7 is connected to the movable frame 63. The collection mechanism 7 includes two symmetrically arranged connecting plates 71, and the two symmetrically arranged connecting plates 71 are fixedly connected to the movable frame 63. A collection frame 72 is fixedly connected between the two symmetrically arranged connecting plates 71. The collection frame 72 is located below the cleaning sleeve 65. A scraper 73 is fixedly connected to the collection frame 72. The scraper 73 is in contact with the cleaning sleeve 65. The scraper 73 is inclined towards the cleaning sleeve 65. A through hole is formed at the bottom end of the collection frame 72. A collection box 74 is clamped at the bottom end of the collection frame 72. The collection box 74 communicates with the through hole. During the rotation of the cleaning sleeve 65, some of the sprayed melt on the cleaning sleeve 65 falls into the collection frame 72. At the same time, during the rotation of the cleaning sleeve 65, it contacts the scraper 73. The scraper 73 scrapes the surface of the cleaning sleeve 65, so that the sprayed melt is separated from the cleaning sleeve 65. The separated sprayed melt falls into the collection frame 72. The sprayed melt in the collection frame 72 passes through the through hole and enters the collection box 74, preventing the sprayed melt from falling onto the belt conveyor 2.

[0026] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
