Description

Technical Field

[0001] This utility model relates to the field of calendering machine technology, and specifically to an adjustment mechanism for a fabric calendering machine. Background Technology

[0002] In the modern textile industry, fabric calendering is one of the important processes for improving fabric quality. A fabric calender applies pressure and temperature to the fabric, making its surface smoother and flatter, thereby improving its appearance and performance.

[0003] However, existing fabric calenders face some problems in practical applications. When the fabric itself has uneven thickness, thicker areas will bear relatively greater pressure during calendering, while thinner areas will receive less pressure. This is mainly because existing calenders typically operate based on overall pressure settings and cannot automatically adjust for localized thickness differences in the fabric. If the fabric is unevenly woven or has thickness variations after previous processing, uneven pressure can easily occur during calendering. This uneven pressure will affect the calendering effect. Utility Model Content

[0004] To overcome the aforementioned technical problems, the practical purpose of this invention is to provide an adjustment mechanism for a fabric calendering machine. Multiple rollers apply pressure to the fabric. When one roller applies localized pressure to a thicker section of the fabric, the other parallel rollers effectively limit the pressure, preventing uneven tension that could lead to fabric deformation and affect quality. This significantly improves calendering stability. A primary motor drives the extrusion unit to the location requiring localized pressure, and a secondary motor drives the corresponding roller to apply localized pressure to the thicker sections of the fabric. This makes the fabric thickness closer to the average level, improving the overall smoothness of the fabric, enhancing product quality, and making its gloss closer to that of the thinner sections, resulting in a more uniform and consistent gloss across the entire fabric.

[0046] Specifically, during operation, the pressure application unit 110 applies pressure to the fabric as a whole according to the set pressure. The electric telescopic rod 211 drives the square shell 212 to move downwards, with the same pressure set by the pressure application unit 110, driving multiple rollers 215 to simultaneously apply pressure to the fabric. An ultrasonic thickness sensor is fixed on the calender near the calendering adjustment mechanism 100. The fabric passes between the probes.

When it detects that the thickness at a certain point is greater than the average thickness, the first motor 222 drives the spur gear 223 to rotate and mesh with the rack 221, driving the extrusion unit... When component 230 moves to the designated position, motor 232 drives threaded rod 233 to rotate and engage with round tube 234, causing telescopic rod 237 to press down on the corresponding inclined block 219. This causes roller 215 to apply localized pressure to the thicker parts of the fabric. When the thicker parts of the fabric are large, dual-axis motor 241 drives two threaded rods 242 to rotate and engage with square rod 243. This causes inclined block 244 to move to one side until it contacts roller 215 next to the corresponding roller 215 and applies pressure. This allows the three adjacent rollers 215 to apply pressure to the fabric simultaneously, expanding the pressure range.

[0047] Example 1

[0048] like Figures 2-4 As shown, in this embodiment, the pressurizing unit 210 includes the following parts: its electric telescopic rod 211 is fixed to the calender support frame, a square shell 212 is fixedly connected to the outer wall of one end of the electric telescopic rod 211, its long rod 213 is fixed to the bottom end of the square shell 212 located on one side, a plurality of rotating seats 214 are slidably inserted into the outer wall of the long rod 213, and rollers 215 are rotatably connected to the rotating seats 214, its square plate 218 is fixed to the outer wall of the rotating seats 214, an inclined block 219 is fixedly connected to the outer wall of the square plate 218, and its spring 216 is fixed between the outer wall of the rotating seats 214 and the inner wall of the square shell 212.

[0049] In this embodiment, the pressure application unit 110 drives the fabric to be pressurized as a whole according to the set pressure. The electric telescopic rod 211 drives the square shell 212 to move downward, and the same pressure is set as the pressure application unit 110. This drives multiple rollers 215 to pressurize the fabric simultaneously. When one roller 215 applies local pressure to a thicker fabric, the other rollers 215 in parallel can effectively limit the pressure, avoid uneven tension, fabric deformation, and affect quality, and effectively improve the stability of calendering.

[0050] like Figure 3 and Figure 5As shown, in this embodiment, the local calendering mechanism 200 includes the following parts: a square rod 220 is fixed to one side of the bottom end of a square shell 212; a rack 221 is fixedly connected to the outer wall of the square rod 220; the extrusion unit 230 includes a T-shaped shell 231, the outer wall of the T-shaped shell 231 is slidably inserted into the outer wall of the square rod 220; a first motor 222 is fixed to the outer wall of the T-shaped shell 231; a spur gear 223 is fixedly connected to the shaft of the first motor 222; and the spur gear 223 is connected to... The rack and pinion 221 engages in a transmission, and its second motor 232 is fixed inside the T-shaped shell 231. A threaded rod 233 is fixedly connected to the shaft of the second motor 232, and a round tube 234 is screwed onto the outer wall of the threaded rod 233. A telescopic rod 237 is fixedly connected to the outer wall of one end of the round tube 234. The ring frame 235 slides on the outer wall of the round tube 234. Two fixed rods 236 are fixedly connected at equal angles to the outer wall of the ring frame 235, and the outer wall of the fixed rods 236 is fixed to the inner wall of the T-shaped shell 231.

[0051] In practice, when a thickness greater than the average is detected at a certain point, motor 222 drives spur gear 223 to rotate and mesh with rack 221, moving extrusion unit 230 to a designated position. Motor 232 drives threaded rod 233 to rotate and screw into round tube 234, causing telescopic rod 237 to press down on the corresponding inclined block 219, which in turn drives roller 215 to apply localized pressure to the thicker parts of the fabric. By driving motor 222, extrusion unit 230 can be quickly moved to the position requiring localized pressure, and motor 232 drives roller 215 to apply localized pressure to the thicker parts of the fabric, making the thickness closer to the average level. This improves the overall smoothness of the fabric, enhances the quality of the product, and makes its gloss closer to that of the thinner parts, resulting in a more uniform and consistent gloss across the entire fabric.

[0052] Example 2

[0053] like Figure 5 As shown, in this embodiment, the diffuser unit 240 includes the following parts: its dual-axis motor 241 is fixed to the inner wall of the T-shaped shell 231, and threaded rods 242 are fixedly connected to the rotating shafts at both ends of the dual-axis motor 241. One end of the threaded rod 242 is rotatably connected to the outer wall of the T-shaped shell 231. Its square rod 243 is screwed onto the outer wall of the threaded rod 242 and is slidably inserted into the inner wall of the T-shaped shell 231. The inclined block 244 slides on the outer wall of the square rod 243 and is fixed to the outer wall of one end of the telescopic rod 237.

[0054] In the specific implementation, when the range of the thicker part of the fabric is large, the biaxial motor 241 drives the two threaded rods 242 to rotate and engage with the square rod 243, drives the inclined block 244 to move to the side to contact the roller 215 near the corresponding position roller 215, and pressurizes, so that the adjacent three rollers 215 simultaneously pressurize the fabric, expand the pressurization range, and through the pressure expansion unit 240, multiple rollers 215 can be simultaneously pressurized, the pressurization range is expanded, each part of the thicker part can be uniformly pressurized, so that the entire fabric has a high degree of uniform flatness after calendering, and the strainability and linkage are effectively improved.
