DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses a fabric flat width shaping device, referring to Figure 1 , including a plurality of guide rollers 1, which are horizontally arranged and parallel to each other. Under the action of the end winding device, the fabric passes through the plurality of guide rollers 1 in sequence and moves forward.

[0025] Reference Figure 1 and Figure 2 The shaping equipment also includes a spray mechanism, shaping devices arranged on both sides of the spray mechanism, a drying device arranged downstream, and a cleaning mechanism arranged upstream of the spray mechanism to clean the surface of the fabric. The spray mechanism is used to spray water vapor at high temperature to remove wrinkles on the surface of the fabric and achieve shaping at the same time. The shaping device is used to pull the fabric horizontally, on the one hand to flatten the fabric for shaping by the spray mechanism, and on the other hand to remove impurities such as fibers on the surface of the fabric.

[0026] Reference Figure 1 The cleaning mechanism includes two spray pipes 2, which are parallel to each other and located on both sides of the fabric. A plurality of cleaning nozzles 3 for spraying the fabric are installed on the spray pipes 2. Under the action of the water pump, clean water enters the spray pipes 2 and is sprayed out from the cleaning nozzles 3. The high-pressure water column acts on the surface of the fabric to flush impurities such as fibers and hair on the surface of the fabric. The connecting lines of the plurality of cleaning nozzles 3 on the spray pipes 2 are located on the same straight line and are evenly distributed along the straight line. The plurality of cleaning nozzles 3 on the spray pipes 2 are inclined from the middle toward the outside in the width direction of the fabric, so that the impurities on the surface of the fabric move along both sides of the width direction of the fabric during the cleaning process.

[0027] Reference Figure 1 and Figure 2 The shaping device includes a rotating wheel rotatably connected to the frame, the lower surface of the fabric contacts the surface of the rotating wheel, the two rotating wheels rotate in opposite directions under the action of the motor, and the two rotating wheels stretch and position the fabric horizontally during the rotation process. The rotating wheel is hollow inside, and a plurality of air inlet holes 4 are opened on the side wall of the rotating wheel. The plurality of air inlet holes 4 are evenly distributed along the circumference of the rotating wheel. A suction fan is fixed to the frame by bolts, and the suction fan is connected to the rotating wheel through a pipeline. When the suction fan is working, air enters the rotating wheel from the air inlet hole 4, and under the action of negative pressure, the fabric is adsorbed on the side wall of the rotating wheel, which is convenient for stretching and positioning the fabric.

[0028] Reference Figure 2 and Figure 3 The rotating wheel includes two coaxial and hollow positioning wheels 5, and a mounting wheel 6 coaxially fixed to the inner wall of the corresponding positioning wheel 5. The mounting wheel 6 is hollow inside and connected to the positioning wheel 5. A plurality of connecting cylinders 7 are rotatably connected to the mounting wheel 6. The plurality of connecting cylinders 7 are connected to the two corresponding mounting wheels 6. The axis of the connecting cylinder 7 is parallel to the mounting wheel 6. The plurality of connecting cylinders 7 are evenly distributed along the circumference of the mounting wheel 6, and the side walls of the connecting cylinder 7 protrude from the side walls of the positioning wheel 5, so that the connecting cylinder 7 beats the fabric to a certain extent during the rotation of the mounting wheel 6, so as to clean the impurities on the surface of the fabric and shape the fabric.

[0029] Reference Figure 2 and 3 A connecting pulley 8 is coaxially fixed on the rotating shaft of the connecting cylinder 7, and a connecting belt 9 is arranged on the connecting pulley 8 to surround a plurality of connecting pulleys 8 on the same positioning wheel 5. A connecting motor 10 is fixed on the mounting wheel 6 to drive one of the pulleys 8 to rotate, and the plurality of connecting cylinders 7 rotate in the direction of lateral stretching of the fabric. The plurality of connecting cylinders 7 rotate with the positioning wheel 5 on the one hand, and rotate around their own axis on the other hand, and apply lateral tension to the fabric at the same time, so that the fabric can be fixed more firmly.

[0030] Reference Figure 3 and Figure 4, a plurality of ventilation holes 11 are provided on the connecting tube 7, and a plurality of connecting holes 12 are provided on the rotating shaft of the connecting tube 7 to connect the connecting tube 7 with the mounting wheel 6. The suction fan acts on the positioning wheel 5 and the connecting tube 7 at the same time, so as to firmly adsorb the fabric on the positioning wheel 5 and the connecting tube 7. The connecting tube 7 includes a plurality of coaxially fixed connecting rings, and the connecting ring includes two semicircular rings. The ventilation holes 11 are provided on one of the semicircular rings. The ventilation holes 11 on the two adjacent connecting rings are staggered. The ventilation holes 11 on the two connecting tubes 7 at the same position on the relative mounting wheels 6 face in opposite directions. Such a design structure ensures that the force acting on the fabric is always in the width direction, and on the other hand, it is to achieve better lateral stretching of various parts of the fabric.

[0031] Reference Figure 1 A blower 13 is fixed above the upstream shaping device. The blower 13 is located above the fabric. A blast pipe 14 is fixed on the air outlet pipe of the blower 13. The blast pipe 14 is parallel to the fabric. The blast pipe 14 is provided with a plurality of blast holes for blowing away impurities on the surface of the fabric.

[0032] Reference Figure 1 and Figure 2 A cleaning pool 15 for immersing part of the positioning wheel 5 and the connecting tube 7 is provided below the positioning wheel 5. The cleaning pool 15 is filled with clean water. A scraper plate 16 for scraping off impurities on the positioning wheel 5 and the connecting tube 7 is fixed in the cleaning pool 15. A collecting bucket 17 for collecting impurities is provided in the cleaning pool 15. A circulating pump 18 for making clean water flow along the collecting bucket 17 is also provided in the cleaning pool 15. During the flow of clean water, impurities are collected in the collecting bucket 17.

[0033] Reference Figure 1 The spray mechanism includes two vertically arranged and parallel spray plates 19. The fabric passes through the two spray plates 19 in the vertical direction. The spray plates 19 are equipped with a plurality of spray heads 20 for spraying high-temperature steam on both sides of the fabric. The distances from both sides of the fabric to the spray heads 20 are equal. The high-temperature steam acts on the fabric to facilitate the removal of fabric wrinkles, thereby ensuring the subsequent drying and shaping.

[0034] Reference Figure 1 The drying device includes a drying box 21 with openings at the upper and lower ends. Two vertically arranged and parallel electric heating plates 22 are fixed in the drying box 21. The fabric passes between the two electric heating plates 22 in the vertical direction. The distances from both sides of the fabric to the electric heating plates 22 are equal to ensure the consistency of temperature on both sides.

[0035] The implementation principle of the embodiment of the present application is as follows: the fabric is flushed by the cleaning nozzle 3, so that the impurities adsorbed on the surface of the fabric are separated from the fabric toward the two sides of the fabric. After the cleaned fabric is initially squeezed, it passes through the shaping device. During the rotation of the positioning wheel 5, under the joint action of the positioning wheel 5 and the connecting tube 7, the fabric is driven to be stretched in the width direction. On the one hand, the suction fan is used to make the fabric more firmly adsorbed on the positioning wheel 5, and on the other hand, it is used to absorb the impurities remaining on both sides of the fabric, so as to achieve the effect of spreading the fabric and cleaning the impurities. At the same time, the adsorbed impurities enter the cleaning tank 15 for collection, and the fabric is dewrinkled and shaped under the action of the high-temperature steam of the spray head 20, and the shaping is completed under the action of the drying device at a later stage.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
