Technical Field

[0001] The utility model relates to the technical field of fabric calendering, in particular to a fabric calendering machine. Background Art

[0002] Calendering is a common textile finishing process that aims to improve the surface finish and smoothness of fabrics through physical or chemical means. This process typically involves heating and pressing the fabric with high-temperature, high-pressure rollers. This method aligns the fibers tightly and reduces surface hairiness, resulting in a better gloss and feel.

[0003] According to the Chinese patent announcement number: CN220844777U, a fabric calender feeding tension control device includes a box body, in which a tension control component and a calendering component are provided; the tension control component includes a tension roller, which is arranged between two guide rollers and connected to the cylinder through a crossbeam; the cylinder includes a shell, a piston is slidably arranged in the shell, and the piston is fixedly installed with a piston rod, and the end of the shell away from the piston rod is threadedly connected to a mounting plate through a mounting port, and the mounting plate is penetrated by two mounting holes, which are respectively threadedly connected to an air intake component and an adjustable safety valve; the adjustable safety valve includes a valve body, an exhaust groove and an adjustment groove are provided in the valve body, the exhaust groove and the adjustment groove are connected through a trapezoidal groove, and the side wall of the adjustment groove is provided with an exhaust port, the adjustment groove is threadedly connected to an adjusting rod, the trapezoidal groove is provided with an adjusting ball, and an adjusting spring is connected between the adjusting ball and the adjusting rod.

[0004] In the above scheme, the fabric is calendered by a pressure roller that is rotatably arranged on the box body, which still has the following disadvantages: the two pressure rollers calender the fabric face to face close to each other, and the thickness of the fabric may be different. The pressure applied by the pressure rollers to the fabric is fixed, and the calendering effect on the fabric is reduced when calendering fabrics of different thicknesses. Utility Model Content

[0005] The purpose of the utility model is to provide a fabric calender to solve the problem that the thickness of the fabric may be different, and the pressure applied by the pressure roller to the fabric is fixed, which reduces the calendering effect of the fabric when calendering fabrics of different thicknesses.

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] Preferably, a positioning plate is fixed to the top surface of the mounting plate, and a rotating rod is rotatably inserted into the positioning plate.

[0008] Preferably, a sliding opening is provided on one side of the mounting plate, a support plate is rotatably provided inside the sliding opening, and an arc-shaped opening is provided on the top surface of the support plate.

[0009] Preferably, limiting grooves are respectively provided on both sides of the interior of the sliding opening, a limiting plate is slidably provided inside the sliding opening, and both sides of the limiting plate are slidably inserted into the two limiting grooves.

[0010] Preferably, two blocking discs are fixed on the top surface of the limiting plate, and a lifting ring is fixed on the top surface of the limiting plate.

[0011] Preferably, two stabilizing plates are fixed on the top surface of the mounting plate, a moving rod is slidably inserted on the stabilizing plate, an extrusion bar is slidably provided above the mounting plate, one side of the extrusion bar is fixed to one end of the moving rod, a push spring is wrapped around the moving rod, one end of the push spring is fixed to one side of the stabilizing plate, and the other end of the push spring is fixed to one side of the extrusion bar.

[0012] Compared with the existing technology, a fabric calender adopting the above technical solution has the following beneficial effects:

[0013] First, the fabric is calendered between two hot-pressing rollers. As the thickness of the fabric increases the height of the upper hot-pressing roller, the lifting plate is also raised, and the extrusion spring is stretched. Therefore, the upper hot-pressing roller, under the action of its own gravity and the pulling force provided by the contraction and recovery of the extrusion spring, can increase the pressure on the fabric between the two hot-pressing rollers. When the thickness of the fabric is different, the length of the extrusion spring is also different, so the pulling force exerted by the extrusion spring on the lifting plate can be adaptively adjusted, thereby improving the calendering effect for fabrics of different thicknesses;

[0014] Second, the uncalendered fabric will be wound on the reel mounted on the rotating rod. When the fabric on the reel is calendered, the staff will apply an upward force to the limit plate through the pull ring to pull the limit plate out of the limit slot. Then the staff can apply a rotating force to the support plate, so that the support plate changes from being perpendicular to the mounting plate to being parallel to each other. At this time, the staff can pull out the reel on the rotating rod and replace it with a new reel with fabric wrapped around it. The reel can be quickly replaced to add fabric, which increases the calendering efficiency of the fabric.

[0015] 3. When the hot pressing roller is rotated to pull the fabric wrapped on the reel, the extrusion strip will fit the surface of the outermost fabric. At this time, the push spring is in a compressed state. The compressed push spring will exert a force on the extrusion strip toward the fabric, which can flatten the fabric pulled away by the hot pressing roller and prevent the fabric from wrinkling when being calendered.

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, a fabric calender comprises a mounting plate 1, the top surface of the mounting plate 1 is fixed with two fixed plates 2, a lifting plate 3 is slidably arranged above the fixed plate 2, hot pressing rollers 4 are rotatably arranged between the two fixed plates 2 and the two lifting plates 3, the surfaces of the two hot pressing rollers 4 are in contact with each other, a motor 5 is fixed on one side of the fixed plate 2 and the lifting plate 3, a rotating hole 6 is opened on one side of the fixed plate 2 and the lifting plate 3, one end of the output shaft of the motor 5 passes through the rotating hole 6 and is fixed to one end of the hot pressing roller 4, two sliding grooves 7 are fixed on the top surface of the fixed plate 2, two sliding rods 8 are fixed on the bottom surface of the lifting plate 3, the sliding rods 8 and the sliding grooves 7 are slidably inserted, and an extrusion spring 9 is surrounded by the surface of the sliding rod 8, one end of the extrusion spring 9 is fixed to the bottom surface of the lifting plate 3, and the other end of the extrusion spring 9 is fixed to the top surface of the fixed plate 2.

[0023] During use, the fabric will be calendered between the two hot pressing rollers 4. Since the thickness of the fabric will increase the height of the upper hot pressing roller 4, the lifting plate 3 will also rise in height, and the extrusion spring 9 will be stretched. Therefore, the hot pressing roller 4 at the top will increase the pressure on the fabric between the two hot pressing rollers 4 under the action of its own gravity and the pulling force provided by the contraction and recovery of the extrusion spring 9. When the thickness of the fabric is different, the length of the extrusion spring 9 is stretched is also different, and the pulling force applied by the extrusion spring 9 to the lifting plate 3 can be adaptively adjusted, thereby increasing the calendering effect on fabrics of different thicknesses.

[0024] like Figure 2 and Figure 4 As shown, a positioning plate 10 is fixed to the top surface of the mounting plate 1, and a rotating rod 11 is rotatably inserted on the positioning plate 10. A sliding opening 12 is provided on one side of the mounting plate 1, and a support plate 13 is rotatably provided inside the sliding opening 12. An arc-shaped opening 14 is provided on the top surface of the support plate 13, and limiting grooves 15 are respectively provided on both sides of the interior of the sliding opening 12. A limiting plate 16 is slidably provided inside the sliding opening 12, and both sides of the limiting plate 16 are slidably inserted into the two limiting grooves 15 respectively. Two blocking disks 17 are fixed to the top surface of the limiting plate 16, and a pulling ring 18 is fixed to the top surface of the limiting plate 16.

[0025] During use, the uncalendered fabric will be wound on the reel mounted on the rotating rod 11. When the fabric on the reel is calendered, the staff will apply an upward force to the limit plate 16 through the pull ring 18 to pull the limit plate 16 out of the limit groove 15. Then the staff can apply a rotational force to the support plate 13, so that the support plate 13 changes from being perpendicular to the mounting plate 1 to being parallel to each other. At this time, the staff can pull out the reel on the rotating rod 11 and replace it with a new reel wrapped with fabric. The reel can be quickly replaced to add fabric, which increases the calendering efficiency of the fabric.

[0026] like Figure 4 As shown, two stabilizing plates 19 are fixed to the top surface of the mounting plate 1, and a moving rod 20 is slidably inserted on the stabilizing plate 19. An extrusion bar 21 is slidably provided above the mounting plate 1, and one side of the extrusion bar 21 is fixed to one end of the moving rod 20. A push spring 22 is wrapped around the moving rod 20, and one end of the push spring 22 is fixed to one side of the stabilizing plate 19, and the other end of the push spring 22 is fixed to one side of the extrusion bar 21.

[0027] During use, when the hot pressing roller 4 is rotated to pull the fabric wrapped on the reel, the squeezing strip 21 will fit the surface of the outermost fabric. At this time, the push spring 22 is in a compressed state. The compressed push spring 22 will apply a force toward the fabric on the squeezing strip 21, which can flatten the fabric pulled away by the hot pressing roller 4 and prevent wrinkles from appearing on the fabric when it is calendered.
