Description

Technical Field

[0001] This application relates to the technical field of textile fabric post-processing equipment, and in particular to a polyester fabric anti-wrinkle heat setting machine. Background Technology

[0002] Fabric heat setting machines are core equipment in the textile finishing process. They are specialized machines that use controlled high temperatures, pressures, and time to physically or chemically modify fabrics, thereby stabilizing fabric dimensions and improving their appearance and functionality. Essentially, they utilize heat energy to break some of the molecular bonds within the fabric fibers, and then use cooling to fix the new molecular arrangement, thus optimizing and stabilizing fabric performance.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN205329351U, which discloses a relaxation heat setting machine, including a dehumidification zone, a body in the dehumidification zone, an air inlet and an air outlet on the body, the air inlet being located on the lower side of the body, the air outlet being located on the upper side of the body, a heat exchanger, a first fan and a second fan being provided outside the body, the air outlet duct of the first fan passing through the heat exchanger and then connected to the air inlet, the air outlet duct of the second fan passing through the heat exchanger and then discharged to the outside; the air intake of the first fan is located outside the body, and the air intake of the second fan is connected to the air outlet.

[0004] However, during the operation of the aforementioned setting machine, the fabric surface is relatively loose, so the fabric is easily wrinkled and deformed when subjected to wind force, which is not conducive to the subsequent unwinding and winding of the fabric. Utility Model Content

[0005] To address the problems of existing heat setting machines causing fabrics to wrinkle and deform due to surface relaxation, hindering subsequent unwinding and winding, and resulting in uneven setting effects and poor wrinkle resistance, this application provides a wrinkle-resistant heat setting machine for polyester fabrics.

[0006] This application provides a wrinkle-resistant heat setting machine for polyester fabrics, which adopts the following technical solution: A heat-setting machine for wrinkle-resistant polyester fabric includes a machine body with a setting cavity inside. A guiding mechanism is provided on the machine body to guide the fabric into the setting cavity. A heating mechanism is provided on the machine body to heat and set the fabric within the setting cavity. An ironing mechanism is also provided on the machine body to iron the heat-set fabric, the ironing mechanism comprising: The upper ironing roller and the lower ironing roller are rotatably mounted on the machine body. The upper ironing roller is located above the lower ironing roller. Both the upper ironing roller and the lower ironing roller are equipped with heating wires. A fabric spreading assembly, which is disposed on the machine body and is used to flatten the fabric that enters between the upper ironing roller and the lower ironing roller; An elastic pressing component is provided on the machine body. The elastic pressing component is used to adjust the position of the upper ironing roller in the vertical direction. Under the action of the elastic pressing component, the upper ironing roller cooperates with the lower ironing roller to clamp the fabric.

[0007] By adopting the above technical solution, the fabric is guided by the guiding mechanism and smoothly enters and exits the shaping cavity. The heating mechanism is used to shape the fabric in the shaping cavity at high temperature. The electric heating wire can heat the upper and lower ironing rollers when energized, so that the fabric can be ironed twice under the dual action of "heating + pressing" when passing through the upper and lower ironing rollers, eliminating wrinkles that may be generated during the heating and shaping process. At the same time, thanks to the adaptive design of the elastic pressing component, it can ensure that the fabric is stably clamped and avoid damage to the fabric due to excessive roller pressure, thus improving the adaptability of the equipment to fabrics of different specifications.

[0008] Optionally, the display assembly includes: Mounting bracket, which is mounted on the machine body; Two spreading rollers are rotatably mounted on a mounting frame and symmetrically arranged along the width of the fabric. The two spreading rollers are distributed in a figure-eight shape. Spreading ridges extending spirally along their axes are integrally formed on the outer peripheral wall of each spreading roller. The spiral directions of the spreading ridges on the two spreading rollers are opposite.

[0009] By adopting the above technical solution, when the fabric passes through the two spreading rollers, the spiral convex strips that rotate with the spreading rollers will "spread" the fabric to both sides in the width direction, eliminating the lateral looseness and wrinkles of the fabric in advance, providing a flat fabric base for the subsequent ironing process, and further improving the wrinkle resistance effect.

[0010] Optionally, the elastic holding component includes: The slider has a vertical sliding groove on its inner side wall, and the slider is slidably mounted on the sliding groove. The upper ironing roller is rotatably mounted on the slider. A spring, one end of which is disposed on the top wall of the sliding groove, and the other end of which is connected to the top of the slider.

[0011] By adopting the above technical solution, the spring force can always provide downward pressure to the upper ironing roller. When the fabric passes between the two rollers, the spring will compress adaptively according to the fabric thickness, ensuring that the upper ironing roller always fits the fabric surface, avoiding insufficient or excessive pressure due to fabric thickness fluctuations, and ensuring the stability of the ironing effect.

[0012] Optionally, the guiding mechanism includes an infeed guiding component and an outfeed guiding component. The infeed guiding component includes an infeed frame fixed to the infeed end of the machine body and two infeed guiding rollers spaced apart vertically. The outfeed guiding component includes an outfeed frame fixed to the outfeed end of the machine body and two outfeed guiding rollers spaced apart vertically.

[0013] By adopting the above technical solutions, the infeed guide roller can guide the fabric to enter the setting cavity accurately, avoiding fabric deviation and uneven setting; the outfeed guide roller can guide the set fabric to exit the machine body smoothly, reducing friction damage between the fabric and the machine body edge, and at the same time, it can cooperate with the subsequent cooling mechanism to achieve orderly conveying.

[0014] Optionally, a tensioning assembly is provided between the fabric guide assembly and the ironing mechanism. The tensioning assembly includes a tensioning frame and a tensioning roller. The tensioning frame has a vertical waist-shaped hole. The two ends of the tensioning roller are slidably inserted into the waist-shaped hole. An adjusting bolt for adjusting the height of the tensioning roller is threaded through the top of the tensioning frame.

[0015] By adopting the above technical solution, rotating the adjusting bolt can drive the tension roller to move up and down along the waist-shaped hole: rotating the adjusting bolt clockwise moves the tension roller down, increasing the fabric tension; rotating it counterclockwise moves the tension roller up, decreasing the tension. By precisely adjusting the tension, the fabric can be kept taut during the conveying process, avoiding slack and wrinkles, while providing stable conditions for subsequent cooling and winding.

[0016] Optionally, the heating mechanism includes: An electric heating element is provided, and the electric heating element is evenly distributed along the length of the molding cavity on the inner top wall and bottom wall of the molding cavity; A temperature sensor is disposed on the inner wall of the middle part of the molding cavity; A thermostat is mounted on the machine body and is electrically connected to both the electric heating element and the temperature sensor.

[0017] By adopting the above technical solution, the operator sets the target setting temperature through the temperature controller, which then activates the electric heating elements upon receiving the setting command. The electric heating elements, staggered along the inner top and bottom walls, heat the air inside the setting chamber simultaneously. A temperature sensor collects real-time temperature data from the chamber and transmits it to the temperature controller. If the temperature is lower than the set value, the temperature controller increases the power of the electric heating elements; if the temperature is higher than the set value, the temperature controller reduces the power or stops heating, maintaining a stable temperature inside the chamber. This ensures that the fabric completes molecular bond recombination under a constant high-temperature environment, achieving dimensional stability and wrinkle-resistant setting.

[0018] Optionally, the machine body is provided with a cooling mechanism for cooling the fabric discharged from the fabric guide roller. The cooling mechanism includes: A cooling roller, which is rotatably mounted on the machine body, has an annular cavity inside. The cooling roller has an inlet pipe and an outlet pipe, which are respectively connected to both ends of the cooling roller and to the cavity. A coolant circulation pump is connected to the outside of the inlet pipe, and a coolant tank is connected to the outside of the outlet pipe.

[0019] By adopting the above technical solution, the coolant circulation pump can pump low-temperature coolant into the annular cavity of the cooling roller, and achieve heat exchange through the contact between the surface of the cooling roller and the fabric, thereby quickly reducing the fabric temperature, avoiding secondary deformation of the fabric due to residual heat, and improving the convenience of subsequent winding.

[0020] Optionally, the machine body is provided with a drive assembly for driving the lower ironing roller to rotate, the drive assembly including: A drive motor is mounted on the outer wall of the machine body; A drive gear, which is mounted on the output shaft of the drive motor; A driven gear is mounted on the shaft of the lower ironing roller and meshes with a driving gear. The diameter of the driving gear is smaller than that of the driven gear.

[0021] By adopting the above technical solution, the drive motor can reduce the rotation speed of the lower ironing roller through the reduction transmission of "small driving gear + large driven gear", ensuring stable fabric conveying speed and avoiding fabric stretching deformation or insufficient shaping due to speed fluctuations.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By energizing the heating wire, the upper and lower ironing rollers can be heated, allowing the fabric to be ironed twice under the dual action of "heating + pressing" when passing through the upper and lower ironing rollers. This eliminates wrinkles that may be generated during the heating and shaping process. At the same time, thanks to the adaptive design of the elastic pressing component, it can ensure that the fabric is stably clamped and avoid damage to the fabric due to excessive roller pressure, thereby improving the equipment's adaptability to fabrics of different specifications. 2. The spring force can always provide downward pressure to the upper ironing roller. When the fabric passes between the two rollers, the spring will compress adaptively according to the fabric thickness, ensuring that the upper ironing roller always fits the fabric surface, avoiding insufficient or excessive pressure due to fluctuations in fabric thickness, and ensuring the stability of the ironing effect. 3. A coolant circulation pump can pump low-temperature coolant into the annular cavity of the cooling roller. Heat exchange is achieved through the contact between the surface of the cooling roller and the fabric, which quickly reduces the fabric temperature and prevents secondary deformation of the fabric due to residual heat. At the same time, it improves the convenience of subsequent winding. Attached Figure Description

The end shaft of the tensioning roller 52 slides through the waist-shaped hole. An adjusting bolt 53 is threaded through the top of the tensioning frame 51 and is threadedly connected to the shaft of the tensioning roller 52.
