Description

Technical Field

[0001] This application belongs to the field of calendering machine technology, and in particular relates to a fabric calendering machine. Background Technology

[0002] Fabric calendering is a textile process that uses the plasticity of fibers under high pressure or high temperature to flatten or roll out parallel fine diagonal lines on the surface of the fabric to enhance its luster. A fabric calendering machine is a piece of equipment used for fabric calendering.

[0003] Existing fabric calenders can calender fabrics, but their heating rollers are usually heated by electric heating wires directly heating the rollers, which can easily lead to uneven heating. This needs to be improved. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a fabric calendering machine that can improve the heating uniformity during fabric calendering and ensure the quality of fabric calendering.

[0005] This application provides a fabric calender, including a calender body, the calender body comprising:

[0006] A jetting device used to eject water vapor;

[0007] Guide rollers, several of which are mounted on the calender body, are used to guide the movement of the fabric;

[0008] A heating roller is movably mounted on the body of a calender. The heating roller includes a roller body, end seats, a heating shaft, and heating wires. The end seats are mounted at both ends of the roller body. The heating shaft is provided with a shaft portion that is connected to the end seats by a bearing. The heating wires are installed in the heating shaft. The roller body contains a heat-conducting medium that completely immerses the heating shaft.

[0009] The pressure roller, in conjunction with the heating roller, calenders the fabric.

[0010] The end seat is provided with a sealing oil plug.

[0011] The jetting device has nozzles connected to a steam-generating device. Hot steam is ejected through the jetting device and applied to the fabric, humidifying it and increasing its plasticity. The fabric is guided as it moves by guide rollers. After passing through heating rollers and pressure rollers, the fabric is calendered. The heating rollers are heated by heating wires connected to a power source. The heating wires are mounted on a heating shaft, and the heat from the heating wires is transferred to the heating shaft. The entire heating shaft is immersed in a heat-conducting medium, which can be oil or water. The fluidity of the heat-conducting medium ensures uniform heat transfer to the roller, resulting in a uniform temperature distribution on the roller surface and further guaranteeing the calendering quality of the fabric. End seats are installed at both ends of the roller and are connected to the roller by bolts or other fasteners. The end seats are connected to the shaft on the heating shaft by bearings, allowing the roller to rotate as the fabric moves during calendering. The pressure roller is hinged to the calender and a sealing oil plug facilitates the addition of heat-conducting medium to the roller.

[0012] Furthermore, the heating shaft includes:

[0013] A spiral heat-conducting plate is placed on the outer wall of the heating shaft;

[0014] The spiral heat-conducting plate includes two spiral plates with different spiral directions, which are respectively disposed at both ends of the heating shaft.

[0015] Spiral heat-conducting plates are welded to the outer wall of the heating shaft. The spiral heat-conducting plates increase the heat conduction efficiency between the heating shaft and the heat-conducting medium. With two spiral heat-conducting plates with opposite spiral directions distributed on the heating shaft, when the roller body and the heating shaft rotate relative to each other, the heat-conducting medium will not flow in one direction, making the heat-conducting medium more evenly distributed in the roller body, thereby ensuring the uniformity of heat distribution on the roller body.

[0016] Furthermore, the heating shaft also includes:

[0017] The mounting holes are provided in several sizes and are evenly distributed around the axis of the heating shaft.

[0018] The mounting holes are machined on the heating shaft by drilling. The axis of the mounting holes is parallel to the axis of the heating shaft. The mounting holes are distributed at both ends of the heating shaft, and the mounting holes at both ends are evenly distributed around the axis of the heating shaft. Compared with a single heating wire installed at the axis of the heating shaft, it has the performance of being able to heat the outer wall surface of the heating shaft more evenly and quickly.

[0019] Furthermore, the heating shaft also includes:

[0020] The annular groove connects to the mounting hole and is located at the end of the heating shaft;

[0021] The sealing cap is installed and connected to the annular groove.

[0022] The annular groove is formed by turning or milling. The annular groove at the same end of the Weiyu heating shaft is connected to the mounting hole. After the heating wire is installed in the mounting hole, the sealing cover fits into the annular groove. The sealing cover and the annular groove are connected by bolts. The sealing cover can prevent the heat transfer medium from flowing into the annular groove and the mounting hole, ensuring the electrical stability of the heating wire. The heating wire and the heating shaft are fixed in the annular groove by bolts and other fasteners.

[0023] Furthermore, the heating shaft also includes:

[0024] Wiring hole, connecting the end face of the shaft to the annular groove.

[0025] The wiring hole in the shaft extends along its axis, extending inward from the end face of the shaft to the corresponding annular groove position. Then, the wiring hole in the annular groove extends radially along the heating shaft into the annular groove. The wiring hole facilitates the passage of the conductive wire on the heating wire used for connecting the power supply.

[0026] Furthermore, the roller body includes:

[0027] The grooves are provided with several evenly distributed grooves on the inner wall surface of the roller.

[0028] The grooves can improve the efficiency of heat transfer from the heat transfer medium to the roller body, and the grooves can give the roller body higher structural strength. The grooves can also make the heat transfer medium flow more stably in the roller body.

[0029] Furthermore, the calender body also includes:

[0030] The adjusting seat is movably mounted to the pressure roller;

[0031] The screw is installed between the adjusting seat and the calender body.

[0032] The adjusting seat and the pressing roller are connected by bearings, and the adjusting seat and the screw are connected by threads. By rotating the screw, the movement of the adjusting seat can be controlled, thereby adjusting the distance between the pressing roller and the heating roller, and realizing the adjustment and control of the pressing force.

[0033] Furthermore, the calender body also includes:

[0034] A temperature detection device is used to detect the surface temperature of the heating roller.

[0035] The temperature detection device uses an infrared temperature sensor to detect the temperature of the heating roller surface, which in turn is used to adjust and control the working state of the heating wire, ensuring the stability of the heating roller surface temperature and further ensuring the quality of fabric calendering.

[0036] The beneficial effects of this application are:

[0037] 1. The heating shaft is completely immersed in the heat-conducting medium of the roller body. Through the efficient flow of the heat-conducting medium, the heat conduction to the roller body is kept uniform, so that the temperature distribution on the surface of the roller body is uniform.

[0038] 2. Two spiral heat-conducting plates with opposite spiral directions are distributed on the heating shaft. When the roller rotates relative to the heating shaft, the heat-conducting medium has two-way flow, which improves the uniformity of the heat-conducting medium distribution.

[0039] 3. The mounting holes, ring grooves, end caps, and wiring holes facilitate the installation of the heating wire and the laying of the power supply wires. Attached Figure Description

[0050] Jet device 110, used to eject water vapor;

[0051] Guide rollers 120 are provided, and several are installed on the calender body 100 to guide the movement of the fabric.

[0052] A heating roller 200 is movably mounted on the calender body 100. The heating roller 200 includes a roller body 210, an end seat 220, a heating shaft 230, and a heating wire 240. The end seat 220 is mounted at both ends of the roller body 210. The heating shaft 230 is provided with a shaft portion 231 that is connected to the end seat 220 by a bearing. The heating wire 240 is installed in the heating shaft 230. The roller body 210 contains a heat-conducting medium that completely immerses the heating shaft 230.

[0053] The pressure roller 300, in conjunction with the heating roller 200, calenders the fabric.

[0054] The end seat 220 is provided with a sealing oil plug 221.

[0055] The jetting device 110 has a nozzle connected to a steam-generating device. Hot steam is ejected through the jetting device 110 and applied to the fabric, humidifying it and increasing its plasticity. The fabric is guided as it moves along the guide roller 120. After passing through the heating roller 200 and the pressure roller 300, the fabric is calendered. The heating roller 200 is heated by a heating wire 240 connected to a power source. The heating wire is mounted on a heating shaft 230, and the heat from the heating wire is transferred to the heating shaft 230. The heating shaft 230 is entirely immersed in the heat-conducting medium of the roller body 210. The heat-conducting medium is oil or... Water conducts heat, and the fluidity of the heat transfer medium ensures uniform heat transfer to the roller body 210, resulting in a uniform temperature distribution on the surface of the roller body 210. This further guarantees the calendering quality of the fabric by the heating roller 200. End seats 220 are installed at both ends of the roller body 210 and are connected to the roller body 210 by bolts or other fasteners. The end seats 220 are connected to the shaft portion 231 on the heating shaft 230 by bearings, allowing the roller body 210 to rotate as the fabric moves during calendering. The pressure roller 300 is hinged to the calender and the addition of heat transfer medium to the roller body 210 is facilitated by the sealing oil plug 221.

[0059] The spiral heat-conducting plate 232 includes two spiral plates with different spiral directions, which are respectively disposed at both ends of the heating shaft 230.

[0060] The spiral heat-conducting plate 232 is welded to the outer wall of the heating shaft 230. The spiral heat-conducting plate 232 increases the heat conduction efficiency between the heating shaft 230 and the heat-conducting medium. With two spiral heat-conducting plates 232 with opposite spiral directions distributed on the heating shaft 230, when the roller body 210 and the heating shaft 230 rotate relative to each other, the heat-conducting medium will not flow in one direction, making the heat-conducting medium more evenly distributed in the roller body 210, thereby ensuring the uniformity of heat distribution on the roller body 210.

Compared with a single heating wire 240 installed at the axis of the heating shaft 230, it has the performance of being able to heat the outer wall surface of the heating shaft 230 more evenly and quickly.

[0064] Furthermore, the heating shaft 230 also includes:

[0067] The annular groove 234 is formed by turning or milling. The annular groove 234 at the same end of the heating shaft 230 is connected to the mounting hole 233. After the heating wire 240 is installed in the mounting hole 233, the sealing cover 235 cooperates with the annular groove 234. The sealing cover 235 and the annular groove 234 are connected by bolts. The sealing cover 235 can prevent the heat transfer medium from flowing into the annular groove 234 and the mounting hole 233, ensuring the energization stability of the heating wire 240. The heating wire 240 and the heating shaft 230 are fixed in the annular groove 234 by bolts and other fasteners.

[0068] Furthermore, the heating shaft 230 also includes:

[0069] Wiring hole 236 is connected between the end face of shaft 231 and annular groove 234.

[0070] The wiring hole 236 in the shaft portion 231 extends along its axis, extending inward from the end face of the shaft portion 231 to the corresponding position of the annular groove 234. Then, the wiring hole 236 in the annular groove 234 is provided to extend radially along the heating shaft 230 into the annular groove 234.
