Description

Technical Field

[0001] The utility model relates to the technical field of cloth preshrinkage, in particular to a cloth preshrinkage shaping device. Background Art

[0002] After the fabric is put into water, it is soaked by water, the fibers swell, the yarn diameter becomes thicker, the curvature of the warp and weft yarns increases, thereby increasing the weaving shrinkage rate, the warp and weft density increases accordingly, the area of ​​the cloth deforms and shrinks, the thickness and density increase, and it cannot be restored by drying. If this kind of fabric is directly cut and sewn without pre-shrinkage treatment, the made garments may become smaller in size or distorted in shape after washing or wearing.

[0003] In order to prevent the fabric from shrinking after being made into clothing, a high-temperature steam shrinking machine is often used to perform high-temperature steam shrinkage treatment on the fabric after the fabric is woven. Under certain temperature, humidity and pressure conditions, the elastic shrinkage deformation of the fabric itself and the penetration and swelling principle of the fabric and fiber are used to eliminate the potential shrinkage of the clothing fabric. The fabric shrinkage treatment equipment in the prior art often places the fabric on a flat mesh belt and heats the fabric with steam to shrink the fabric. Since it is necessary to cool and dry as much as possible after wetting and heating, otherwise the wet fabric is prone to creases during the process of folding into bundles for storage, which affects the quality of the fabric. In order to ensure the cooling and shaping effect, the cooling area occupies a large area, the production line is long, and installation and transportation are difficult.

[0004] For example, a new type of shaping preshrinking machine disclosed in Chinese Patent No.: ZL201620912741.1 includes a cloth feeding device in a cloth feeding section, a steam device in a steam section, a drying device in a drying section, an air drying device in a cooling section, and a cloth stacking device in a cloth outlet section. Each section is spliced ​​into a frame using side boxes on both sides, and a transmission device is installed on the frame; the steam device includes a first side box and a steam cover and a steam plate installed on the first side box; the steam plate is located below the mesh conveyor belt; the steam cover is located above the mesh conveyor belt; the drying device includes a second side box, an electric heating pipe cover and a radiator installed on the second side box, and an electric heating pipe installed on the inner side of the electric heating pipe cover; the electric heating pipe cover is located above the mesh conveyor belt; the radiator is located below the mesh conveyor belt; the air drying device includes a third side box and a cold air cover and a cold air plate installed on the third side box ; The cold air cover is located above the mesh conveyor belt; the cold air plate is located below the mesh conveyor belt; the transmission device is connected to a vibration mechanism, and steam is introduced through the steam plate below the mesh conveyor belt. Under the agitation of the fan, the steam continuously floats upward, thereby humidifying the fabric. After entering the drying stage, the electric heating tube and the radiator work together to dry the fabric. Finally, the cold air plate and the cold air cover are used to discharge air to cool the fabric. However, the cooling section of the device is short, and the fabric immediately enters the cooling section for air drying and folding after passing through the drying section, resulting in water vapor still existing in the fabric that is not completely air dried. Immediate folding is not conducive to the discharge of water vapor, so that creases are formed in the process of folding the fabric into bundles for storage. If the cooling section is extended to increase the cooling time, the floor space of the equipment will be increased, which is not conducive to the transportation and installation of the equipment. Summary of the invention

[0005] The technical problem to be solved by the utility model is how to improve the cooling efficiency of the cloth after pre-shrinking and shaping, and how to improve the pre-shrinking and shaping effect of the cloth while reducing the floor space. The purpose of the utility model is to provide a cloth pre-shrinking and shaping device which can improve the cooling efficiency of the cloth and avoid the formation of creases in the process of folding the cloth into bundles for storage after pre-shrinking due to residual water vapor in the cloth.

[0006] The technical scheme adopted by the utility model is: a cloth pre-shrinking and shaping device, comprising a cloth unwinding frame and a frame, the cloth unwinding frame is installed on one side below the frame, a plurality of rollers arranged in an arc shape are installed at the bottom of the cloth unwinding frame, the plurality of rollers are parallel to each other, and two mutually parallel limiting rods are installed at the top of both ends of the cloth unwinding frame; a moistening area, a drying area and a cooling area are arranged in the frame, the moistening area is arranged above the drying area, the drying area is arranged above the cooling area, the drying area and the cooling area are separated by a partition, a through hole is provided on one side of the partition, and the cooling area is provided with a cooling mesh belt group composed of a plurality of cooling mesh belts arranged from top to bottom.

[0007] The following beneficial effects can be achieved by using the cloth pre-shrinking and shaping device provided by the utility model:

[0008] (1) The cloth roll is placed on the cloth unwinding rack, and the end of the cloth after unwinding is placed in the rack. The cloth is wetted in the wetting area to reduce the force between various groups inside the cloth, and the cloth shrinks freely without tension. The cloth is then dried in the drying area to increase the temperature of the wet cloth and accelerate the evaporation of water. The cloth falls to the cooling area, and the cloth is pre-shrunk and shaped without pressure or stretching. The structure is compact, the pre-shrinking efficiency is high, and it is easy to use.

[0009] (2) A rotating rod is inserted into the core of the cloth roll and then placed between two limit rods at both ends of the cloth unwinding frame. The limit rods limit the displacement of the cross bar to prevent the cloth roll from falling off the cloth unwinding frame during the cloth unwinding process, and the cloth unwinding process is stable.

[0010] (3) After being moistened and dried, the fabric still contains some moisture. The cooling mesh belt group composed of multiple cooling mesh belts arranged from top to bottom in the cooling zone drives the fabric to move and flip repeatedly in a Z-shape, thereby extending the cooling path of the fabric, accelerating the efficiency of moisture dissipation of the fabric, making the fabric completely dry, and preventing the moisture-containing fabric from forming creases during the process of folding into bundles for storage, thereby improving the effect of fabric pre-shrinkage and greatly reducing the floor space occupied by the cooling zone, making installation and transportation more convenient.

[0011] (4) The fabric is fed from top to bottom. After the end of the fabric in the fabric roll is placed in, no manual traction is required. The fabric only changes its moving direction during the process of falling under gravity, so that the fabric is moistened, dried and cooled in sequence without being subjected to tension or traction, thereby stabilizing the pre-shrinkage effect of the fabric. The method is easy to use and has a good pre-shrinkage effect.

[0012] Preferably, the wet zone includes forward and reverse thread rollers, a speed limiting cam, a first mesh belt, a pressure wheel, a second mesh belt and a steam nozzle; the forward and reverse thread rollers and the first mesh belt are arranged in the wet zone outside the frame, a speed limiting cam is provided on the side of the first mesh belt away from the forward and reverse thread rollers, a pressure wheel is also provided on the side above the first mesh belt away from the forward and reverse thread rollers, and the bottom of the pressure wheel is in close contact with the upper surface of the first mesh belt.

[0013] The first mesh belt drives the cloth to move toward the wet area, the pressure wheel provides traction for loosening the cloth roll and initial movement of the cloth, and the speed limiting cam slows down the speed of the cloth when it enters the second mesh belt to avoid preshrinkage failure caused by pressure or traction when the cloth is wet.

[0014] Preferably, one end of the forward and reverse threaded roller away from the first transmission chain is connected to the first mesh belt through a transmission chain.

[0015] When the cloth is put in, it is placed on the upper surface of the positive and negative threaded rollers and then placed on the first mesh belt. When the positive and negative threaded mesh belts rotate synchronously with the first mesh belt, the wrinkles formed when the warp is loosened by the cloth unwinding frame are spread out horizontally through the threaded surfaces at both ends of the positive and negative threaded rollers, so that the cloth enters the frame smoothly, preventing the cloth wrinkles from causing uneven or incomplete wetting of the warp.

[0016] Preferably, the speed limiting cam, the pressure wheel and the second mesh belt are arranged in a wet area in the frame, and the jet outlet of the steam nozzle faces the lower surface of the upper side of the second mesh belt.

[0017] By facing the lower surface of the upper side of the second mesh belt with the air jet port, the steam can immediately contact the cloth entering the second mesh belt after passing through the second mesh belt, thereby improving the efficiency of wetting the cloth. Both high-temperature steam and low-temperature steam are applicable.

[0018] Preferably, the ends of the first mesh belt, the second mesh belt and the speed limiting cam are provided with transmission shafts for transmission, and the transmission shafts extend out of the frame. A first transmission motor is fixed to the outside of the frame, and the transmission shafts on the first mesh belt, the second mesh belt and the speed limiting cam are connected to the first transmission motor through a first transmission chain.

[0019] The first transmission chain is driven to rotate by the motor, and the first mesh belt, the second mesh belt and the transmission shaft at the end of the speed limiting cam driven by the first transmission chain rotate synchronously, so that the first mesh belt, the second mesh belt and the speed limiting cam rotate synchronously, which is convenient for sending the cloth after being loosened by the cloth unwinding rack into the wet zone, reducing the number of installed motors, thereby reducing the energy consumed when the cloth is moved.

[0021] When the steam-moistened cloth passes through the drying area where the vibrating conveyor is located, the drying efficiency of the cloth is accelerated by vibrating and heating at the same time. The speed limiting cam and the vibrating conveyor prevent the cloth from being subjected to pressure or tension during the drying process. In the initial stage of placing the cloth, there is no need for manual traction to change the movement path of the cloth, which is easy to use.

[0022] Preferably, the cooling zone includes a staggered mesh belt group, a guide sprocket, a third transmission motor and a second transmission chain. The staggered mesh belt group is composed of multiple parallel cooling mesh belts arranged from top to bottom, and the ends of the multiple cooling mesh belts are staggered with each other; one end of the transmission shaft that plays a transmission role in the staggered mesh belt group extends out of the frame and is fixedly connected to the transmission sprocket, the outer sides of the frame above and below the staggered mesh belt group are rotatably connected to the guide sprocket, and the third transmission motor is fixed outside the frame.

[0023] By arranging a plurality of parallel cooling mesh belts from top to bottom, only the moving direction of the cloth from the drying zone to the cooling zone is changed by the running direction of the multi-layer cooling mesh belts. At the same time, the length of the cooling zone is greatly reduced by the plurality of cooling mesh belts arranged from top to bottom, thereby reducing the footprint of the device and facilitating installation and transportation. The ends of the plurality of cooling mesh belts are staggered with each other, and the cloth can be caught by the cooling mesh belt below when it falls from the upper cooling mesh belt to the lower cooling mesh belt, utilizing the moving path that cannot be changed by the cooling mesh belts, and preventing the cloth from falling vertically by the cooling mesh belts staggered at the ends, so that the cloth can be cooled by the staggered mesh belt group during the movement process, thereby making the dryness of the cloth consistent.

[0024] Preferably, the second transmission chain passes through the outside of multiple transmission sprockets and wraps around the two guide sprockets at the top and bottom to be connected to the third transmission motor. When the third transmission motor rotates, each layer of cooling mesh belt is driven to rotate through the second transmission chain, and the movement directions of two adjacent cooling mesh belts are opposite.

[0025] The second transmission chain is driven to rotate by the third transmission motor, and the direction of the second transmission chain around the third transmission motor and the transmission sprocket is changed by the guide sprocket. After the second transmission chain rotates around the guide sprocket, it drives multiple transmission sprockets connected to the cooling mesh belt to rotate synchronously, so that all cooling mesh belts in the staggered mesh belt group can rotate synchronously, and the movement directions of two adjacent cooling mesh belts are opposite, so that the cooling time of the cloth in the cooling zone is extended through the staggered mesh belt group, and the cloth can be quickly cooled in the process of continuous movement and turning, the water vapor content and temperature in the cloth are reduced, and the cooling efficiency of the cloth is improved.

[0026] Preferably, the rack is provided with an air inlet, a first air outlet, and a second air outlet, the air inlet is arranged on one side of the bottom of the rack, the first air outlet is arranged on the top of the rack, a centrifugal exhaust fan is also arranged on the top of the first air outlet, one end of the second air outlet is opposite to the air inlet and is arranged on a side of the bottom of the rack away from the air inlet, and the other end of the second air outlet is connected to the bottom of the first air outlet.

[0027] Air is transported through the air inlet at the bottom of the frame to speed up the air flow rate in the cooling zone, thereby increasing the speed at which heat and water vapor from the fabric in the cooling zone are discharged; excess heat and water vapor in the wet zone are discharged through the first air outlet and the centrifugal exhaust fan on top of the first air outlet. The centrifugal exhaust fan can also introduce air mixed with heat and water vapor in the cooling zone after entering from the air inlet into the first air outlet for discharge together, thereby speeding up the dissipation of moisture and heat from the fabric after wet pre-shrinkage, and preventing residual moisture in the fabric from forming creases during the process of folding into bundles for storage.

[0028] Preferably, a cloth outlet is provided at the bottom of the frame.

[0029] The cloth outlet at the bottom of the frame allows the cloth to move from top to bottom and fall from the outlet after pre-shrinking and drying, thereby preventing the cloth from being pulled and deformed, stabilizing the pre-shrinking and shaping effect, and facilitating the storage of the cloth after it falls from the outlet.

Then, the end of the cloth is pulled out from the cloth roll, and placed on the first mesh belt 253 from above the positive and negative threaded rollers 251. Then, the device is started, and the pressing wheel 254 and the first mesh belt 253 form a downward pulling force on the end of the cloth to pull the cloth upward into the wet area 25 in the frame 2. The speed limiting cam 252 rotates to make the cloth under the pulling force The cloth recovers the relaxed state under the action of the speed limiting cam 252, and then falls on the second mesh belt 255 under the action of gravity and moves with the second mesh belt 255. During the movement, the steam sprayed from the steam nozzle 256 in the middle of the second mesh belt 255 passes through the upper surface of the second mesh belt 255 to wet the cloth, and the stress of the cloth is reduced through the principle of cloth penetration and swelling, so that the force between various groups inside the cloth is reduced, and the cloth freely shrinks in a tension-free state. The wetted cloth continues to move and fall with the second mesh belt 255 and enters the drying area 26;

[0057] After entering the drying area 26, the cloth falls on the vibrating conveyor 261 and moves in the opposite direction with the third mesh belt 2611 on the vibrating conveyor 261. At the same time, the wet cloth is heated by the heater 262 in the third mesh belt 2611, so that the water absorbed by the cloth begins to evaporate. Combined with the centrifugal exhaust fan 23 on the first exhaust port 22 on the frame 2, the water vapor containing a large amount of water is sucked into the first exhaust port 22 and discharged to the outside of the frame 2. At the same time, the cloth is vibrated up and down quickly by the vibrator 2612 in the vibrating conveyor 261, which speeds up the drying speed of the cloth, avoids the cloth from being subjected to tension or traction, and facilitates the shrinkage of the cloth. The dried cloth passes through the through hole on the partition 263 and falls downward into the cooling area 27;

[0058] The cloth entering the cooling zone 27 falls on the staggered mesh belt group 271, and the cloth falls layer by layer through the multi-layer cooling mesh belts 2711 arranged from top to bottom in the staggered mesh belt group 271. At the same time, since the movement directions of the two adjacent layers of cooling mesh belts 2711 are opposite, the cloth moves in a Z shape with the cooling mesh belts 2711 during the downward falling process, and is turned over after each layer falls downward. The airflow introduced from the air inlet 21 on the frame 2 accelerates the evaporation speed of the water in the cloth, so that the evaporated water vapor enters the second air outlet 24 with the air flow and is discharged to the outside of the frame 2 through the suction action of the centrifugal exhaust fan 23 with the second air outlet 24;

[0059] The cloth falls and turns over many times, and the evaporation rate of water vapor is accelerated by ventilation, so that the moisture in the pre-shrunk cloth can be discharged as much as possible, and creases can be prevented from being generated in the subsequent folding process of the cloth into bundles. Since the cloth in the cooling zone 27 falls naturally from top to bottom under the action of gravity, and the movement direction of the cloth is a Z-shaped reciprocating movement, the cooling zone 27 is extended as long as possible to discharge moisture while reducing the volume of the cooling zone 27, thereby reducing the overall footprint of the device, thereby achieving pre-shrinking and shaping of the cloth without pressure and stretching, and making the cloth thoroughly dry, thereby improving the quality of the pre-shrunk cloth. The structure is compact, easy to use, easy to transport and install, and has a wide range of promotion and application value in the technical field of cloth pre-shrinkage.
