Description

Technical Field

[0001] This utility model relates to the technical field of fabric textiles, and in particular to a calendering device with adjustable pressure. Background Technology

[0002] A calender is a piece of equipment used in the textile process to improve the luster, smoothness, and uniformity of fabrics. It flattens the fabric to prevent wrinkles from appearing on its surface.

[0003] Existing calendering devices, such as the adjustable multi-roller calendering device disclosed in utility model patent application number 201620784620.3, mainly include a base and two columns fixed on the base. One side of the column is the input end, which is equipped with a lifting conveyor table. The other side of the column is the calendering end, and a calendering seat extends from the top of the column at the calendering end. A limiting guide rail is provided on the column below the calendering seat, and a fixed seat is fixed in the middle of the limiting guide rail. A fabric support roller is installed between the two fixed seats, and an upper calendering roller is provided above the fabric support roller. An upper adjusting cylinder is provided on the calendering seat. In use, the distance between the calendering roller and the fabric support roller can be adjusted by the upper and lower adjusting cylinders to adapt to calendering fabrics of different thicknesses, and to calender fabrics of the same thickness to different degrees. The lifting conveyor table can be adjusted arbitrarily according to the thickness of the fabric.

[0004] However, most existing calendering devices do not clean the fabric before calendering. Impurities accidentally rolled into the fabric can easily affect the calendering effect. Moreover, most existing calendering devices only perform one roller press, which makes it difficult to achieve the predetermined calendering requirements. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an adjustable pressure calendering device that not only cleans and blows the fabric before calendering to avoid impurities affecting the calendering effect, but also enhances the calendering effect by adding pressure rollers and heating the fabric.

[0006] This utility model discloses an adjustable pressure calendering device, including a support mechanism; it also includes a tensioning mechanism, a traction mechanism, a cleaning mechanism, a blowing mechanism, and a calendering mechanism. The tensioning mechanism is installed on the support mechanism and tensions the fabric. The traction mechanism is installed on the support mechanism and drives the tensioning mechanism to reciprocate. The cleaning mechanism is installed on the traction mechanism and cleans the surface of the fabric. The blowing mechanism is installed on the cleaning mechanism and blows the fabric. The calendering mechanism is installed on the support mechanism and calenders the fabric. The fabric to be calendered is placed on the support mechanism. The tensioning mechanism prevents the fabric from loosening and spreads the fabric out. The calendering mechanism drives the fabric forward and calenders it. Before calendering, the traction mechanism drives the cleaning mechanism to clean the surface of the fabric. At the same time, the blowing mechanism blows the cleaned impurities out of the calendering range of the fabric to prevent impurities from affecting subsequent calendering.

[0007] Preferably, the support mechanism includes a worktable, two sets of limiting plates, a take-up roller, and two sets of retaining rings. The bottom end of the worktable is connected to the ground, and the bottom ends of the two sets of limiting plates are connected to the top end of the worktable. Each set of limiting plates has a positioning groove. The take-up roller is rotatably installed in the positioning groove of the two sets of limiting plates, and the two sets of retaining rings are installed on the take-up roller. The fabric to be calendered is rolled up on the take-up roller, and the two sets of retaining rings are used to position both sides of the fabric. Then, the take-up roller is placed in the positioning groove of the two sets of limiting plates to facilitate the unfolding of the fabric. One end of the fabric is placed on the calendering mechanism, and the calendering mechanism is adjusted to press the fabric tightly.

[0008] Preferably, the tensioning mechanism includes a rotating shaft, two sets of springs, two sets of connecting rods, and a tensioning roller. The rotating shaft is rotatably mounted between two sets of limiting plates. The two sets of springs are respectively mounted on the two sets of limiting plates and are both connected to the rotating shaft. The two sets of connecting rods are both mounted on the rotating shaft. The tensioning roller is rotatably mounted between the two sets of connecting rods. The tensioning roller presses down on the fabric on the take-up roller to prevent the fabric from loosening. As the fabric decreases, the two sets of springs rebound and drive the rotating shaft to rotate. When the rotating shaft drives the two sets of connecting rods to rotate, the tensioning roller gradually presses down to keep the fabric taut.

[0009] Preferably, the traction mechanism includes a lead screw box, a motor, a reducer, a first transmission shaft, a reciprocating lead screw, two sets of pulleys, and a belt. The lead screw box is mounted on two sets of limit plates and has a sliding groove. The bottom end of the motor is connected to the top end of the lead screw box, the bottom end of the reducer is connected to the top end of the lead screw box, and the output end of the motor is connected to the input end of the reducer. The first transmission shaft is mounted on the reducer, and the reciprocating lead screw is rotatably mounted in the sliding groove of the lead screw box. The two sets of pulleys are respectively mounted on the first transmission shaft and the reciprocating lead screw, and the belt is tensioned between the two sets of pulleys. When the motor is started, the motor drives the first transmission shaft to rotate through the reducer. The first transmission shaft drives the pulley connected to it to rotate, and the pulley drives the other set of pulleys and the reciprocating lead screw to rotate through the belt. The reciprocating lead screw drives the cleaning mechanism to move back and forth.

[0010] Preferably, the cleaning mechanism includes a slider, two sets of telescopic rods, two sets of springs, and a cleaning brush. The slider is slidably installed in the groove of the screw box. The top ends of the two sets of telescopic rods are connected to the bottom ends of the slider. The two sets of springs are respectively fitted onto the two sets of telescopic rods. The top end of the cleaning brush is connected to the bottom ends of the two sets of telescopic rods. The reciprocating screw drives the slider to move back and forth. By setting two sets of telescopic rods and two sets of springs, the cleaning brush can be kept at the surface of the fabric. The cleaning brush cleans the fabric back and forth, preventing impurities from entering the calendering mechanism with the fabric.

[0011] Preferably, the purging mechanism includes a second drive shaft, an air pump, an air extraction pipe, an air delivery hose, and nozzles. The second drive shaft is mounted on a reducer. The bottom end of the air pump is connected to the top end of the lead screw box, and the input end of the air pump is connected to the second drive shaft. The air extraction pipe is mounted on the air pump, and the air delivery hose is mounted on the cleaning brush. Both sets of nozzles are mounted on the cleaning brush and communicate with the inside of the air delivery hose. The reducer drives the second drive shaft to rotate, and the second drive shaft drives the air pump to extract air. The air pump draws air in through the air extraction pipe and then delivers it to the two sets of nozzles through the air delivery hose. The two sets of nozzles purge the fabric, accelerating the removal of impurities from the fabric.

[0012] Preferably, the calendering mechanism includes a heating roller, a transmission control box, three sets of idler rollers, multiple sets of hydraulic cylinders, a connecting frame, and three sets of pressure rollers.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the fabric to be calendered is placed on the support mechanism, and the tensioning mechanism is set to prevent the fabric from loosening. The fabric is spread out, and the calendering mechanism drives the fabric forward to calender it. Before calendering, the traction mechanism drives the cleaning mechanism to clean the surface of the fabric, and at the same time, the blowing mechanism blows the cleaned impurities out of the calendering range of the fabric to avoid impurities affecting the subsequent calendering.
