Description

Technical Field

[0001] The utility model relates to the technical field of web forming machines, in particular to a non-woven fabric web forming machine. Background Art

[0002] A non-woven fabric web forming machine is a professional equipment for non-woven fabric production. Its main function is to form uniform and tough non-woven fabric through specific technological processes for the pre-treated fiber raw materials, such as carding, web forming, drying, pressing, etc. Air-laid web forming machine: It uses air flow to blow and deposit fibers on the mesh belt to form a fiber web, which has the characteristics of high production efficiency and low energy consumption. Wet-laid web forming machine: It uniformly wets the fibers through a sprayer, and then conducts directional stratification and shortening through a forming mesh to finally form non-woven fabric. The wet-laid web forming machine can manufacture non-woven fabric with better air permeability and water permeability.

[0003] When dealing with broken filaments and lumps in traditional web forming machines, generally workers clean them with a brush or a scouring pad in their hands behind the web forming machine. Due to the long width of the conveyor belt of the web forming machine and the fast conveyor speed, the cleaning range that workers can cover is limited, resulting in low cleaning efficiency and thus affecting the finished product quality of non-woven fabric. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a non-woven fabric web forming machine to solve the problem that when dealing with broken filaments and lumps in traditional web forming machines, generally workers clean them with a brush or a scouring pad in their hands behind the web forming machine. Due to the long width of the conveyor belt of the web forming machine and the fast conveyor speed, the cleaning range that workers can cover is limited, resulting in low cleaning efficiency and thus affecting the finished product quality of non-woven fabric as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A non-woven fabric web forming machine includes a machine shell. A positioning roller is rotatably connected inside the machine shell, and non-woven fabric is wound around the positioning roller. Two rotating rollers are rotatably connected in the machine shell, and the rotating rollers are wound with the non-woven fabric. A fixed seat is fixedly connected to the side wall of the machine shell, and a winding roller is rotatably connected in the fixed seat. The output end of a servo motor is fixedly connected to the central position of the winding roller.

[0007] Furthermore, an electrostatic eliminator is fixedly arranged on the inner side wall of the machine shell.

[0008] Furthermore, a first synchronous pulley is fixedly sleeved on the output end of the servo motor. A transmission belt is sleeved outside the first synchronous pulley, and the other end of the transmission belt is sleeved with a second synchronous pulley. A rotating shaft is fixedly sleeved in the second synchronous pulley.

[0009] Furthermore, two brush rollers are rotatably arranged inside the casing, and spur gears that are meshed with each other are fixedly sleeved on the ends of the two brush rollers.

[0010] Furthermore, two boxes are symmetrically arranged in the casing. A suction port is formed in the box, and the suction port is sleeved on the brush roller. Two connecting seats that are fixedly connected to the inner wall of the casing are symmetrically and fixedly connected to the opposite outer walls of the box. A collection hood that communicates with the inside of the box is fixedly connected to the box. One end of a tee pipe that communicates with the inside of the collection hood is fixedly connected to the end of the collection hood, and the other end of the tee pipe is fixedly connected to the input end of a suction pump.

[0011] Furthermore, comb teeth bars that are fixedly connected to the box are arranged on both sides of the suction port.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The output end of the servo motor drives the winding roller to wind the non-woven fabric. The non-woven fabric is horizontally transported between the winding roller and the rotating roller. The output end of the servo motor can also drive the first synchronous wheel to rotate, and then the second synchronous wheel and the rotating shaft are driven to rotate under the action of the transmission belt. The two spur gears rotate meshingly, and in this way, the brush rollers on the upper and lower parts of the non-woven fabric are driven to rotate in the reverse direction through the rotating shaft. Therefore, the broken filaments and lumps on the upper and lower surfaces of the non-woven fabric can be easily brushed and cleaned by the brush rollers, so that the surface of the non-woven fabric can be automatically treated during the transportation process of the non-woven fabric, and the surface cleaning efficiency of the non-woven fabric is improved.

[0014] 2. Boxes are arranged outside both brush rollers. The comb teeth bars arranged on both sides of the suction port of the box are used to dredge the brush rollers during the rotation of the brush rollers, and then the broken filaments cleaned by the brush rollers are easily removed. Since the box is connected with a tee pipe and a suction pump, the broken filaments removed are sucked into the collection hood by the suction pump for collection through the tee pipe, so that the cleaning effect of the brush rollers on the non-woven fabric can be ensured.

[0015] 3. The static eliminator in the casing facilitates the elimination of static electricity on the surface of the non-woven fabric. Since static electricity will cause the accumulation of surface charges on the non-woven fabric, affecting the appearance and performance of the product. Removing static electricity can significantly reduce this accumulation phenomenon, making the product surface smoother and flatter, improving the overall quality of the product. Static electricity may also have an adverse impact on the hand feeling and air permeability of the non-woven fabric. Removing static electricity can keep these characteristics undamaged.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a non-woven fabric forming machine includes a machine shell 101. A positioning roller 102 is rotatably connected inside the machine shell 101, and a non-woven fabric is wound around the positioning roller 102. Two rotating rollers 103 are rotatably connected in the machine shell 101, and the rotating rollers 103 are wound around the non-woven fabric. A fixed seat 202 is fixedly connected to the side wall of the machine shell 101, and a winding roller 201 is rotatably connected in the fixed seat 202. The output end of a servo motor 203 is fixedly connected to the central position of the winding roller 201; Two brush rollers 209 are rotatably arranged inside the machine shell 101, and spur gears 207 that are meshed with each other are fixedly sleeved at the ends of the two brush rollers 209.

[0024] Specifically, the output end of the servo motor 203 drives the winding roller 201 to wind the non-woven fabric. The non-woven fabric is horizontally transmitted between the winding roller 201 and the rotating roller 103. The output end of the servo motor 203 can also drive the first synchronous wheel 204 to rotate. Then, under the action of the transmission belt 205, the second synchronous wheel 206 and the rotating shaft 208 are driven to rotate. Through the meshing rotation of the two spur gears 207, the brush rollers 209 on the upper and lower parts of the non-woven fabric are driven to rotate in the opposite direction by the rotating shaft 208. Therefore, the broken filaments and lumps on the upper and lower surfaces of the non-woven fabric can be easily brushed and cleaned by the brush rollers 209, so that the surface of the non-woven fabric can be automatically treated during the transportation process of the non-woven fabric, improving the surface cleaning efficiency of the non-woven fabric.

[0025] Embodiment 1

[0027] In this embodiment, the electrostatic eliminator 104 in the machine shell 101 facilitates the elimination of static electricity on the surface of the non-woven fabric. Since static electricity can cause the accumulation of surface charges on the non-woven fabric, affecting the appearance and performance of the product. Removing static electricity can significantly reduce this accumulation phenomenon, making the product surface more flat and smooth, improving the overall quality of the product.
