Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing equipment, in particular to an improved non-woven fabric hot pressing equipment. Background Art

[0002] Non-woven fabric, also known as non-woven cloth, as the name implies, is a fabric formed by bonding and reinforcing a long filament or short fiber web. It is a textile that does not require weaving or knitting processing, has diverse properties, and can have different functions depending on the variety and use. The short fibers are formed into non-woven fabric after being mixed, opened, laid, reinforced, hot pressed, and wound. Among them, hot pressing is an important link to endow the non-woven fabric with good stiffness, hardness, air permeability and other basic properties, and most non-woven fabrics are hot pressed by steel rollers.

[0003] In the existing hot pressing equipment, usually two steel rollers with the same diameter, one on the top and one on the bottom, are used to hot press the non-woven fabric. Although a distance adjusting device is provided between the two steel rollers, the accuracy is too low to be accurately adjusted according to the properties of different non-woven fabrics. Therefore, the surface of the non-woven fabric after this hot pressing is extremely smooth. When it is compounded with other non-woven fabrics, even if it is fixed with glue, the problems of slitting and splitting still exist. In addition, the hardness is too hard and the air permeability is too low. Therefore, the existing hot pressing equipment cannot well meet the basic properties of the non-woven fabric. At the same time, the existing device lacks cleaning measures for the hot pressing steel rollers. Due to the strong adhesion of fibers or fine hairs and other impurities, the effect of ordinary cleaning and removal is not ideal. In view of this, it is necessary to design an improved non-woven fabric hot pressing equipment. Summary of the Utility Model

[0004] In view of the deficiencies in the prior art, the utility model provides an improved non-woven fabric hot pressing equipment.

[0005] An embodiment of the utility model provides an improved non-woven fabric hot pressing equipment, including:

[0006] A machine body, a main body steel roller is fixedly connected between the inner side walls of the machine body, sliding grooves are arranged on both inner side walls of the machine body, two first cylinders are fixedly connected to the upper surface of the machine body through brackets, the output ends of the two first cylinders penetrate through the upper surface of the machine body and extend into the two sliding grooves respectively, the output ends of the two first cylinders are fixedly connected with bearing blocks, and an auxiliary steel roller is rotatably connected between the adjacent side walls of the two bearing blocks;

[0007] An auxiliary cleaning mechanism, the auxiliary cleaning mechanism includes a rubber roller, a guiding roller assembly and a cleaning assembly.

[0008] Further, the rubber roller and the guiding roller assembly include multiple groups of cylinder components fixedly connected to the inner walls on both sides of the machine body through brackets. Each group of cylinder components includes two corresponding No. 2 cylinders. Fixed sleeves are fixedly connected to the output ends of the two No. 2 cylinders in each group of cylinder components. A rubber roller is rotatably connected between the fixed sleeves at the output ends of the two No. 2 cylinders in each group of cylinder components. A No. 1 guiding roller is rotatably connected between the inner walls of the machine body. No. 2 cylinders are fixedly connected to the side walls on both sides of the machine body through brackets. Mounting sleeves are fixedly connected to the output ends of the two No. 2 cylinders. A No. 2 guiding roller is rotatably connected between the two mounting sleeves.

[0009] Further, the cleaning assembly includes a motor fixedly connected to the inner bottom surface of the machine body through a bracket. Multiple connecting plates are equidistantly and fixedly connected to the inner bottom surface of the machine body. A No. 1 rotating shaft is fixedly connected to the output end of the motor. The No. 1 rotating shaft passes through and is rotatably connected to the side walls of the multiple connecting plates through bearings. Above the multiple connecting plates, there are No. 2 rotating shafts. The multiple No. 2 rotating shafts are respectively rotatably connected to the inner bottom surfaces of the multiple connecting plates through bearings. Multiple No. 1 bevel gears are fixedly connected to the circumference of the No. 1 rotating shaft at equal intervals. No. 2 bevel gears are fixedly connected to the bottom ends of the multiple No. 2 rotating shafts. The multiple No. 1 bevel gears are respectively meshed with the multiple No. 2 bevel gears. Blowing fan blades are fixedly connected to the top ends of the multiple No. 2 rotating shafts.

[0010] Further, multiple placing rollers are rotatably connected between the inner walls on both sides of the machine body.

[0011] Further, the multiple rubber rollers are arranged in a ring around the main steel roller, and the included angle between two adjacent rubber rollers is sixty degrees.

[0012] Further, the number of the rubber rollers is five, and the number of the placing rollers is three.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, the combination of the steel roller and the rubber roller is adopted to avoid the problem of the single structure that the surface of the non-woven fabric after hot pressing treatment is too smooth. The surface of the non-woven fabric in contact with the steel roller is smooth, and the surface of the non-woven fabric extruded near the rubber roller has a burr structure. This burr structure greatly increases the probability of compounding with other non-woven fabrics by using the entanglement phenomenon between fibers, solves the problems of slitting and splitting of the composite non-woven fabric, and improves the service performance of the composite non-woven fabric.

[0015] 2. In the utility model, the combined use of the rubber rollers, on the one hand, endows the non-woven fabric with a burr structure, and on the other hand, the application of the cylinders enables the extrusion of the rubber rollers on the non-woven fabric to be kept within a reasonable range, endowing the non-woven fabric with good air permeability and stiffness, so that the non-woven fabric after hot pressing is not rigid and inflexible.

[0016] 3. In the present utility model, the included angle between adjacent rubber rollers is stably maintained at sixty degrees, ensuring the uniform stress of non-woven fabric extrusion and avoiding the "pitting" problem on the surface of the hot-pressed non-woven fabric caused by unstable roller shafts due to too large or too small included angles.

[0017] 4. In the present utility model, through the arranged cleaning assembly, a single power output drives multiple cleaning components to work. While saving the usage cost, the fiber fine hairs attached to the steel roller are removed by wind power, which has a higher cleaning efficiency compared with the traditional cleaning method.

[0027] An auxiliary cleaning mechanism, which includes a rubber roller, a guiding roller assembly and a cleaning assembly. The rubber roller and the guiding roller assembly include a plurality of groups of cylinder components fixedly connected to the two inner side walls of the machine body 1 through brackets. Each group of cylinder components includes two corresponding second cylinders 7. The output ends of the two second cylinders 7 in each group of cylinder components are fixedly connected with fixing sleeves 8. A rubber roller 9 is rotatably connected between the fixing sleeves 8 at the output ends of the two second cylinders 7 in each group of cylinder components. A first guiding roller 10 is rotatably connected between the inner walls of the machine body 1. Second cylinders 7 are fixedly connected to both side walls of the machine body 1 through brackets. The output ends of the two second cylinders 7 are fixedly connected with mounting sleeves 11. A second guiding roller 12 is rotatably connected between the two mounting sleeves 11. A plurality of rubber rollers 9 are arranged in a ring around the main body steel roller 2, and the included angle between two adjacent rubber rollers 9 is sixty degrees. By arranging a plurality of equidistant rubber rollers 9 around the main body steel roller 2, the force on the non-woven fabric is more uniform during the hot pressing process. The number of rubber rollers 9 is five, and the number of placing rollers 20 is three. The diameter of all five rubber rollers 9 is 200 mm;

[0028] The cleaning assembly includes a motor 13 fixedly connected to the inner bottom surface of the machine body 1 through a bracket. A plurality of connecting plates 14 are fixedly connected to the inner bottom surface of the machine body 1 at equal intervals. The output end of the motor 13 is fixedly connected with a first rotating shaft 15. The first rotating shaft 15 passes through and is rotatably connected to the side walls of the plurality of connecting plates 14 through bearings. A plurality of second rotating shafts 16 are provided above the plurality of connecting plates 14. The plurality of second rotating shafts 16 are respectively rotatably connected to the inner bottom surfaces of the plurality of connecting plates 14 through bearings.

[0029] The detailed working process of the present utility model is as follows:

[0030] During use, an oil heating device is connected inside the main steel roller 2. After being heated, the heat-conducting oil enters the hollow main steel roller 2 to heat the main steel roller 2. The heating temperature is 140 - 190 °C. The heating temperature of the main steel roller 2 is determined according to the melting point of the non-woven fabric and the fiber ratio. After that, the raw material is hot-pressed into non-woven fabric under the cooperation of the main steel roller 2 and the auxiliary steel roller 6. During processing, multiple rubber rollers 9 are precisely controlled by multiple second cylinders 7. At the same time, the auxiliary steel roller 6 is also precisely controlled by the first cylinder 4. The precise control is achieved by the precision pressure regulating valves installed on each cylinder, and the pressure of the air pump is 0.1 - 0.6 MPa, so as to precisely adjust the hot-pressing distance and be accurately adjusted according to the performance of different non-woven fabrics. After the hot-pressing operation of the non-woven fabric is completed under the cooperation of the main steel roller 2, the auxiliary steel roller 6 and multiple rubber rollers 9, the finished non-woven fabric is wound up by the first guiding roller 10 and the second guiding roller 12 to complete the collection of the finished non-woven fabric;

[0031] After subsequent use, since it is a hot-pressing operation for non-woven fabric, some fine fiber hairs will adhere to the main steel roller 2, the auxiliary steel roller 6 and the rubber roller 9. When cleaning is required, start the motor 13. The motor 13 drives the first rotating shaft 15 to rotate, and then drives multiple first bevel gears 17 to rotate. Through meshing transmission, it drives multiple second bevel gears 18 and the second rotating shaft 16 to rotate, thereby driving multiple blowing fan blades 19 to rotate, generating wind to clean the surfaces of the main steel roller 2, the auxiliary steel roller 6 and the rubber roller 9. Compared with wiping and cleaning operations, the wind removing impurities such as adhered fine fiber hairs will have a better cleaning effect.
