Description

Technical Field

[0001] The utility model relates to the technical field of textile processing, in particular to an edge blowing device which utilizes compressed air to stretch curled edges. Background Art

[0002] During the finishing and shearing process of textiles (especially knitted fabrics), due to the action of tension, some knitted fabrics will have curling on both sides of the fabric (commonly known as curling), which has an adverse effect on the shearing process.

[0003] In the prior art, knitted fabrics are usually tightly attached to the surface of a steel wire roller in a semi-wrap manner, and the steel wire roller expands the width of the knitted fabric to reduce the curling of the fabric edge.

[0004] However, currently, knitted fabrics are inevitably deflected laterally along their conveying direction during transport. As the fabric passes through steel rollers, the friction generated by the steel rollers on the fabric edges can easily cause the fabric to deflect, leading to wrinkles. Therefore, the present invention proposes a side-blowing device that uses compressed air to stretch the curled edges to address this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a blowing device for stretching the curled edge by using compressed air, so as to solve the problem of curling and wrinkling of knitted fabrics during transportation proposed in the above background technology.

[0022] See also Figures 1 to 2 , the utility model provides a technical solution:

[0023] In a first embodiment, a device for blowing an edge using compressed air to stretch a curled edge comprises:

[0024] The guide rail beam 17 is arranged above the knitted fabric and perpendicular to the conveying direction thereof. Figure 1As shown, the conveying direction of the knitted fabric is the up-down direction, the length direction of the guide rail beam 17 is the left-right direction, a guide rail 8 is fixedly connected to the guide rail beam 17, and a slider 9 is slidably installed on the outer side of the guide rail 8. The slider 9 can slide horizontally left and right along the width direction of the knitted fabric to adjust its own position. A mounting base plate 10 is fixedly connected to one side of the slider 9. The mounting base plate 10 is vertically arranged, and a sensor mounting base 19 is installed at the lower end. The sensor in the sensor mounting base 19 can detect the edge of the knitted fabric. The sensor mounting base 19 is close to the knitted fabric from top to bottom, and an air blowing pipe 20 for blowing air to the edge of the knitted fabric is installed on the side of the sensor mounting base 19. The air blowing pipe 20 The blowing direction is from the middle to the edge of the knitted fabric surface, so that when the knitted fabric has curling or wrinkles, the knitted fabric will be stretched and smoothed, ensuring that the surface of the knitted fabric is flat during transportation. In addition, when the sensor in the sensor mounting seat 19 detects that the knitted fabric has shifted left and right during transportation, the position of the air blowing tube 20 can be changed by adjusting the left and right sliding of the slider 9 to ensure that the air blowing tube 20 can always work effectively. A retractable telescopic part 21 is provided in the middle of the mounting seat plate 10. The setting of the retractable part 21 makes the mounting seat plate 10 as a whole have a certain amount of retractability in the vertical direction, which is used to adapt to the vertical jump generated during the transportation of the knitted fabric.

[0025] In order to detect the edge of the knitted cloth, the telescopic part 21 of the present application is a telescopic rod with a built-in spring, which can be extended and reset by itself. It is a structure known in the prior art and will not be described here. The lower surface of the sensor mounting seat 19 is equipped with an edge detection sensor facing the knitted cloth. When the knitted cloth is laterally offset, the distance and direction that the slider 9 will slide next is determined by real-time detection.

[0026] In order to limit the sliding of the slider 9, the present application also has a sliding limiter 7 installed on the guide rail beam 17. The sliding limiter 7 is set in two groups and is located at both ends of the sliding stroke of the slider 9. It can be used to limit the sliding position and distance of the slider 9. In addition, Figure 1 As shown, the sliders 9 of the device are provided with two groups and distributed at the two edges of the knitted cloth, ensuring that there are two groups of blowing pipes 20 blowing at the two edges of the knitted cloth respectively, ensuring the flatness of the surface of the knitted cloth.

[0027] In order to drive the sliding of the slider 9, the present application also has a driving screw 6 parallel to the guide rail beam 17 provided on one side of the driving screw 6, and a screw sleeve 12 is provided on the outer side of the driving screw 6 through a threaded sleeve, and the upper surface of the screw sleeve 12 is fixedly connected to a connecting plate 11, and one end of the connecting plate 11 is fixedly connected to the slider 9. When the driving screw 6 rotates, the screw sleeve 12 can be driven by the thread to slide along the length direction of the sliding limiter 7, and then through the connection of the connecting plate 11, the slider 9 can be driven to slide synchronously. That is to say, the left and right sliding of the slider 9 is controlled by the forward and reverse rotation of the driving screw 6.

[0028] In order to position the driving screw 6, the present application also has a screw positioning seat 13 fixedly connected to the guide rail beam 17 at one end of the driving screw 6, and a bearing seat 15 is installed on the screw positioning seat 13. One end of the driving screw 6 is rotatably inserted into the bearing seat 15 to ensure that the driving screw 6 can only rotate without position displacement.

[0029] In order to drive the driving screw 6 to rotate, the present application also has a mounting base 3 provided at the other end of the driving screw 6, and a reducer 1 is installed on the surface of the mounting base 3. The reducer 1 and the driving screw 6 maintain a transmission connection through the belt transmission component 2 and the screw shaft seat 5. The mounting base 3 and the guide rail beam 17 are both fixedly installed on the frame 18. The reducer 1 is controlled by the motor. When working, the screw shaft seat 5 is driven to rotate through the transmission of the belt transmission component 2, thereby driving the driving screw 6 to rotate.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
