Currently, calenders are widely used in textile finishing, paper processing, and film processing. Due to the varying materials and thicknesses of different sheets, adjustments to the roller spacing and temperature are necessary. Existing calenders only have one type of roller, requiring companies to purchase multiple units, increasing production costs. For example, prior art publication (announcement number): CN218196477U discloses a calender including a gantry frame; a fixed pressure roller horizontally rotatably connected to the gantry frame via two bearing seats fixed to it; and at least one adjustable pressure roller spaced below the fixed pressure roller. Each adjustable pressure roller is horizontally connected to the gantry frame via two drive components. The drive components automatically control the gap between the rollers, adapting to the adjustment needs of multi-roll calenders.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] like Figure 1, Figure 2 As shown, the present invention relates to a multi-roll calender for puncture-resistant fabric, comprising a frame 1, which is vertically arranged, with multiple staggered rollers 2 arranged sequentially from top to bottom. Receiving grooves for the rollers 2 to move up and down are opened at opposite ends of the frame 1. The ends of the rollers 2 pass through the receiving grooves, and the intersection of the rollers 2 and the receiving grooves is connected by bearings. In use, a hydraulic pressurizing device drives the rollers 2 to move synchronously up and down along the receiving grooves via a synchronous drive device. Each roller 2 is equipped with an independent temperature control component, which consists of an annular heat transfer oil channel built into the roller 2, a PID temperature controller, and a circulating pump group. The annular heat transfer oil channel is used to receive and circulate heat transfer oil. The PID temperature controller is connected to a heating and cooling device, which is used to heat and cool the heat transfer oil to achieve temperature control and adjustment. The temperature control range of this component is set to 50-250℃ to adapt to the calendering of most sheet products.

[0016] like Figure 1 As shown, the multiple rollers 2 include carbide rollers 21 and elastic rubber rollers 22, which are staggered with an angle of 30-45°, forming an "S"-shaped fabric channel. The length of this channel is 2.5-3.5m. The fabric passes through the multiple rollers 2 sequentially, and the tension between the rollers 2 keeps the fabric taut. The outer surface of the carbide rollers 21 is plated with a hard chrome layer with a thickness of 0.3-0.5mm. All rollers 2 are installed behind the frame 1, and a synchronous drive device is installed below the lowest roller 2. The synchronous drive device has... There is a crossbeam 4, and at the opposite ends of the crossbeam 4, there are upward extending supports 5. Multiple slots 6 are arranged sequentially from bottom to top on the supports 5. The supports 5 pass through the gaps between multiple rollers 2. Each slot 6 corresponds to a roller 2. A bearing is installed in the slot 6, and one end of the roller 2 extends into the bearing. The synchronous drive device realizes the synchronous movement of the rollers 2 through the supports 5 that support the rollers 2. The driving force of this movement comes from the hydraulic pressurizing device below the crossbeam 4. The hydraulic pressurizing device has a hydraulic cylinder. The output shaft of the hydraulic cylinder is connected to the crossbeam 4, driving the rollers 2 to move up and down, thereby realizing the adjustment of the gap between the rollers 2.

[0017] like Figure 1 , Figure 2As shown, the composite shock-absorbing base 3 located at the bottom of the frame 1 includes a base, a rubber damping layer, and a hydraulic buffer. The frame 1 is mounted on the base, and the rubber damping layer and hydraulic buffer are placed inside the base, with the rubber damping layer positioned below the hydraulic buffer. The composite shock-absorbing base 3 provides good shock absorption for the frame 1, which helps maintain the stability of the frame 1. The vertical multi-roll calender has a simple structure and reasonable layout. The staggered arrangement of multiple rollers 2 facilitates the guidance of the fabric through. Each roller 2 has an independently set temperature control component, which can adjust the temperature on the roller 2 and also achieve different temperatures for different rollers 2, facilitating the hot pressing of products of varying thicknesses. The hydraulic pressurizing device, in conjunction with the synchronous drive device, can achieve synchronous lifting and lowering of the rollers 2, reducing the interval between the rollers 2, improving the application range of the calender, shortening the workflow, and increasing production efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
