Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a rolling mill used for nonwoven fabric production. Background Technology

[0002] Hot rolling is a crucial process in the production of nonwoven hot-rolled fabrics. It is widely used due to its advantages such as high heat and uniform fiber filament distribution. In the processing of nonwoven fabrics, hot rolling and bonding is a key process affecting the surface appearance quality of the nonwoven fabric, determining its tensile strength, elongation, appearance, and hand feel. In existing rolling mills used for nonwoven fabric production, the formed nonwoven fabric is directly wound up and then slit for use. Due to the lack of high-temperature and high-pressure treatment, the nonwoven fabric has poor toughness and insufficient water absorption, significantly reducing its service life. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a rolling mill for nonwoven fabric production, which can precisely control the pressure and temperature of the nonwoven fabric, improve the working stability of the rolling mill for nonwoven fabric production, and ensure the production efficiency of nonwoven fabric.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A rolling mill for nonwoven fabric production includes: a frame, a hot pressing section, and a cooling section, both of which are mounted on the frame; the hot pressing section includes a heating roller and a pressure roller, the pressure roller being movably mounted above the heating roller via a first driving device; the cooling section includes a guide roller, a cooling roller, and a recovery assembly, the guide roller being located between the heating roller and the cooling roller; the recovery assembly includes a recovery roller, a rotating roller, and a second driving device for driving the rotating roller to rotate, the rotating roller being located between the cooling roller and the recovery roller; a limiting block cooperating with the recovery roller is provided on the frame.

[0006] The aforementioned rolling mill for nonwoven fabric production has at least the following beneficial effects: by setting up a hot pressing section and a cooling section, the heating roller and pressure roller can heat the formed nonwoven fabric, and the cooling roller can cool the high-temperature nonwoven fabric, so as to accurately control the pressure and temperature of the nonwoven fabric, improve the working stability of the rolling mill for nonwoven fabric production and the production efficiency of nonwoven fabric; by setting up guide rollers and recovery rollers, the nonwoven fabric that has completed hot pressing and cooling can be stably and quickly wound up, improving the winding efficiency and working stability of the rolling mill for nonwoven fabric production.

[0007] Furthermore, a connecting block is provided between the pressure roller and the driving end of the first driving device. By providing the connecting block, the first driving device can stably drive the pressure roller to move up and down, improving the connection flexibility between the pressure roller and the first driving device.

[0008] Furthermore, the connecting block is provided with connecting holes, and both ends of the pressure roller are inserted into the connecting holes and movably connected to the connecting block. By providing connecting holes, the pressure roller can stably press against the heating roller, improving the heat-pressing stability of the nonwoven fabric and ensuring the production efficiency of the nonwoven fabric.

[0009] Furthermore, a recovery trough is provided at the end of the frame away from the hot pressing section, and the limiting blocks are located on both sides of the recovery trough. By setting the recovery trough, the recovery roller can be quickly conveyed into the recovery trough after completing the winding operation and fixed between the limiting blocks and the second drive device, preventing the recovery roller from falling off and improving the operating efficiency and stability of the rolling mill used for nonwoven fabric production.

[0010] Furthermore, the recovery roller is movably connected to the frame via a limiting groove. By providing the limiting groove, the recovery roller can be flexibly positioned on the frame, allowing the nonwoven fabric to be quickly and stably wound up on the recovery roller, thus ensuring the operational stability of the mill used for nonwoven fabric production.

[0011] Furthermore, a third driving device is provided between the limiting groove and the frame. The third driving device drives the limiting groove to rotate, so that the recovery roller is conveyed onto the recovery groove. By setting up the third driving device, after the recovery roller completes the winding operation, the third driving device can drive the limiting groove and the recovery roller to be stably and quickly conveyed onto the recovery groove, thereby improving the operating efficiency of the rolling mill used for nonwoven fabric production.

[0012] Furthermore, the first driving device is a hydraulic cylinder, while the second and third driving devices are both electric motors. Hydraulic cylinders have the advantages of high thrust and simple structure; using a hydraulic cylinder in the first driving device effectively ensures that the pressure roller presses stably against the heating roller, improving the thermal pressing stability of the nonwoven fabric. Electric motors have the advantages of high control precision, high torque, and low noise; using electric motors in the second and third driving devices effectively improves the winding efficiency of the nonwoven fabric.

[0013] Furthermore, the frame is also equipped with a slider for supporting the recovery roller, the height of which gradually decreases towards the limiting block.

By setting the heating wires and heat dissipation grooves, the heating roller can perform precise heating of the nonwoven fabric, and the cooling roller can perform precise cooling of the nonwoven fabric, thereby improving the temperature control accuracy of the rolling mill used for nonwoven fabric production.

[0015] Furthermore, an indicator light is provided at the upper end of the frame, and the indicator light is electrically connected to the first drive device and the second drive device. By providing the indicator light, operators can intuitively observe the working status of the first drive device and the second drive device, improving the ease of use of the rolling mill for nonwoven fabric production.

[0016] The beneficial effects of the aforementioned rolling mill for nonwoven fabric production are as follows: By setting up a heating section and a recovery section, the heating section can easily heat the solution in the heating guide block and absorb the waste gas generated by the nonwoven filaments through the air inlet, thereby reducing the temperature of the nonwoven filaments passing through the spinneret and improving the uniformity of spinneret production and the production efficiency of nonwoven fabrics; by setting up a feeding block and a spinneret, the solution can stably enter the filament exit plate through the feeding hole and pass through the heating guide hole and spinneret to form nonwoven filaments for outward transmission, improving the working stability of the rolling mill for nonwoven fabric production; by setting up an air duct, the connection stability between the fan and the air inlet is effectively improved, allowing the fan to efficiently and continuously absorb the waste gas generated by the nonwoven filaments during the forming process, improving the environmental performance of the rolling mill for nonwoven fabric production; by setting up protrusions and positioning grooves, the heating guide block and spinneret are accurately positioned and installed, ensuring the positioning accuracy of the heating guide hole and the spinneret, and improving the working stability of the rolling mill for nonwoven fabric production.

[0032] The working principle of this utility model will be further explained below.

[0033] During the assembly process, firstly, according to the on-site installation environment and the production requirements of nonwoven fabric, heating wires of the corresponding specifications are selected as heating wires 211 and fixedly installed in the heating roller 210 so that the heating wires are evenly distributed between the heating rollers 210; heat dissipation grooves 321 are set in the cooling roller 320 and connected to the cooling circulation system; then, the heating roller 210, pressure roller 220, guide roller 310, recovery roller 331 and rotating roller 332 are installed on the frame 100, wherein the pressure roller 220 is movably set above the heating roller 210 through the first drive device 230, the rotating roller 332 is movably connected to the second drive device 333, and the recovery roller 331 is inserted into the limiting groove 334 and movably connected to the third drive device 335; Specifically, the two ends of the pressure roller 220 are inserted into the connecting holes 241 and movably connected to the connecting block 240, so that the first driving device 230 drives the pressure roller 220 to move up and down reciprocally through the connecting block 240. Then, a spare recovery roller 331 is placed on the slider 130 to improve the replacement efficiency of the recovery roller 331. According to the production requirements of nonwoven fabric, the distance between the heating roller 210 and the pressure roller 220, the distance between the guide roller 310 and the recovery assembly 330, and the distance between the cooling roller 320 and the rotating roller 332 are adjusted so that the nonwoven fabric can be hot-pressed between the heating roller 210 and the pressure roller 220 under the drive of the rotating roller 332, and then conveyed to the cooling roller 320 by the guide roller 310, and finally completed in the recovery roller 331 for winding. In this way, the assembly of the rolling mill for nonwoven fabric production is completed. The entire assembly process is efficient and controllable and can be flexibly adjusted according to the needs of the site.

[0034] During use, the formed nonwoven fabric is passed sequentially between the heating roller 210 and the pressure roller 220, between the two guide rollers 310, and between the cooling roller 320 and the rotating roller 332, and finally wound into the recovery roller 331. Next, the first drive device 230, the heating wire, and the second drive device 333 are activated, so that the first drive device 230 drives the pressure roller 220 to move downward, so as to ensure that the nonwoven fabric is hot-pressed between the pressure roller 220 and the heating roller 210. Then, driven by the rotating roller 332, the nonwoven fabric passes between the guide rollers 310 and is quickly transferred to the cooling roller 320 and the rotating roller 332. Since the heat dissipation groove 321 is connected to the cooling circulation system, it can continuously remove the heat of the nonwoven fabric, thereby making the nonwoven fabric cool down and set quickly. Finally, the nonwoven fabric is wound onto the recovery roller 331. After the recovery roller 331 completes winding, the third drive device 335 is activated. The third drive device 335 drives the limiting groove 334 to rotate, so that the recovery roller 331 is transferred to the recovery groove 120. Then, the third drive device 335 drives the limiting groove 334 to reset, and the operator moves the recovery roller 331 on the slider 130 into the limiting groove 334 for winding on the next recovery roller 331. During the production process, the operator can visually observe the working status of the first drive device 230 and the second drive device 333 through the indicator light 140, ensuring the convenience of using nonwoven filaments and the production efficiency of nonwoven fabrics in the rolling mill used for nonwoven fabric production.

[0035] As can be seen from the above description, the rolling mill for nonwoven fabric production of this utility model, by setting up a heating section and a recovery section, facilitates the heating section to heat the solution in the heating guide block, and absorbs the waste gas generated by the nonwoven filaments through the air inlet, thereby reducing the temperature of the nonwoven filaments passing through the spinneret and improving the uniformity of spinneret production and the production efficiency of nonwoven fabric. By setting up a feeding block and a spinneret block, the solution can stably enter the filament exit plate through the feeding hole, and then pass through the heating guide hole and the spinneret hole to form nonwoven filaments for outward transmission, improving the working stability of the rolling mill for nonwoven fabric production. By setting up an air duct, the connection stability between the fan and the air inlet is effectively improved, and the fan can efficiently and continuously absorb the waste gas generated by the nonwoven filaments during the forming process, improving the environmental performance of the rolling mill for nonwoven fabric production. By setting up protrusions and positioning grooves, the heating guide block and the spinneret block can be accurately positioned and installed, ensuring the positioning accuracy of the heating guide hole and the spinneret hole, and improving the working stability of the rolling mill for nonwoven fabric production.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
