Description

Technical Field

[0001] The present invention relates to the technical field of webbing processing, and specifically to a webbing loosening machine for cleaning the wool yarn on the surface of the webbing. Background Art

[0002] A webbing is a narrow fabric or tubular fabric made of various yarns. Among them, the variety of ribbon fabrics is numerous and the application is the most extensive. It is widely used in various industrial sectors such as clothing, shoe materials, luggage, industry, agriculture, military supplies, transportation, etc. The webbing is generally woven and processed by a webbing machine, and during the processing, a webbing loosening machine is also used to comb, spread, and sort the webbing.

[0003] However, when the existing webbing loosening machine combs, spreads, and sorts the webbing, due to the equipment pulling and stretching the webbing during the conveying process, it is easy to cause the surface of the webbing to fuzz, resulting in a wire drawing phenomenon, which affects the quality of the webbing and also affects the decorative effect of the webbing. Moreover, it is not convenient to clean the wool yarn on the surface of the webbing after winding. Therefore, further improvement can be made. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides a webbing loosening machine for cleaning the wool yarn on the surface of the webbing, which has the advantages of being convenient for cleaning the wool yarn on the surface of the webbing and avoiding wire drawing of the webbing, etc., and solves the problems mentioned above.

[0006] (II) Technical Solutions

[0007] To solve the problems mentioned above, the present invention provides the following technical solutions: A webbing loosening machine for cleaning the wool yarn on the surface of the webbing, including a machine body. A workbench is fixedly installed on the top of the machine body. Webbing loosening rollers are rotatably connected to the inner walls on both sides of the workbench. Brackets are fixedly installed on the outer walls on both sides of the workbench. A housing is fixedly installed between the two brackets. An intermittent transmission component is arranged inside the housing, and a wool yarn cleaning component is arranged inside the housing and behind the intermittent transmission component.

[0008] Further, the intermittent transmission component includes a runner and a special-shaped plate rotatably connected inside the housing, and the special-shaped plate is located below the runner. An arc surface is arranged on the outer side of the special-shaped plate corresponding to the outer side of the runner. Chute grooves are opened at the four corners of the special-shaped plate. A rotating plate assembly is arranged on the opening side of the runner. The rotating plate assembly includes a fixed cylinder fixedly installed on the opening side of the runner. A sliding plate is slidably connected inside the fixed cylinder. A rotating column is rotatably connected to one side of the front surface of the sliding plate. A limiting frame is fixedly installed on the inner wall of the fixed cylinder. A sliding rod is slidably connected inside the limiting frame. A compression spring is sleeved on the outer side of the section of the sliding rod located inside the limiting frame.

[0009] Further, the runner is fixedly installed at one end of the output shaft of the built-in motor. The slide plate is located on the back side of the special-shaped plate. As the runner rotates, the rotating column will slide into the chute. The rotation of the runner will drive the entire rotating plate assembly to rotate synchronously. As a result, the rotating column will rotate into the chute. Then, as the runner rotates, it will drive the rotating column to squeeze the special-shaped plate along the inner wall of the chute, causing the special-shaped plate to rotate by a quarter turn.

[0010] Further, one end of the slide rod is fixedly installed on the side of the slide plate inside the fixed cylinder. A sleeve plate is fixedly installed on the outer side of one end of the slide rod. The compression spring is fixedly installed between the sleeve plate and the inner wall of the limit frame. When the rotating column slides into the chute and squeezes the special-shaped plate, the slide plate will slide into the fixed cylinder, thereby compressing the compression spring to prevent the rotating column from jamming when squeezing the special-shaped plate along the inner wall of the chute. Then, the compression spring will drive the slide plate to reset outward.

[0011] Further, the wool cleaning component includes a rotating cylinder fixedly installed on the back side of the special-shaped plate. A shaft rod is fixedly installed at the center of the inside of the rotating cylinder. A triangular scraping plate is fixedly installed on the outer side of the rotating cylinder. The inner wall of the rotating cylinder is rotatably connected to a turntable, and the turntable is sleeved on the outer side of the shaft rod. A collection box is fixedly installed at the bottom of the turntable. An extraction component is arranged on the left side inside the rotating cylinder, and an inner wall cleaning component is arranged on the front side of the turntable.

[0012] Further, four groups of triangular scraping plates are arranged in an array on the outer side of the rotating cylinder. A storage groove is opened inside the triangular scraping plate, and a through groove is opened on the outer side of the rotating cylinder corresponding to the storage groove. When the special-shaped plate drives the rotating cylinder to rotate, the latter group of triangular scraping plates will replace the previous ones. Thus, when the webbing is transported forward, the wool on the surface of the webbing will be scraped and cleaned by the triangular scraping plates, and the cleaned wool will be collected into the storage groove.

[0013] Further, the extraction component includes a micro air pump fixedly installed on the front side of the turntable and a sealing cover fixedly installed on the left side of the turntable. The sealing cover abuts against the inner wall of the rotating cylinder. One end of the air extraction port of the micro air pump is fixedly installed with an air extraction pipe, and the other end of the air extraction pipe communicates with the inside of the sealing cover. The sealing cover corresponds to the left through groove. One side of the air outlet of the micro air pump is fixedly installed with an exhaust pipe, and the other end of the exhaust pipe is located inside the collection box. By starting the micro air pump, the inside of the sealing cover will be evacuated along the air extraction pipe, thereby sucking the wool collected in the left through groove, and finally discharging it into the collection box through the exhaust pipe.

[0014] Further, the inner wall cleaning assembly includes a base fixedly installed on one side of the front surface of the turntable. A rotating rod is rotatably connected to the middle of the base. The other end of the rotating rod is rotatably connected to a swing rod. A upper wedge block is fixedly installed at the bottom end of the swing rod. A lower wedge block is fixedly installed on the outer side of the shaft rod, and five groups of the lower wedge blocks are arranged in an array around the shaft rod. A brush is fixedly installed at the top end of the swing rod, and the brush abuts against the inner wall of the rotating cylinder. As the shaft rod rotates with the rotating cylinder, the lower wedge block will drive to squeeze the upper wedge block, causing the swing rod to deflect with the rotating rod as the axis.

[0015] Further, a torsion spring is fixedly installed on one side of the front surface of the base, and the torsion spring is sleeved on the outer side of the rotating rod. Fixed columns are fixedly installed at both ends of the torsion spring, and the two fixed columns are respectively located on both sides of the swing rod. As the swing rod deflects, the fixed columns will be squeezed to compress the torsion spring, and the compressed torsion spring will drive the swing rod to rotate reversely and reset, causing the swing rod to swing back and forth.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a weft releasing machine for cleaning the wool on the surface of a woven belt, having the following beneficial effects:

[0018] 1. In this weft releasing machine for cleaning the wool on the surface of a woven belt, through the intermittent rotation of the rotating cylinder, the latter set of triangular scraping plates will replace the previous ones, and the wool on the surface of the woven belt is scraped and cleaned by the triangular scraping plates. So when the wool in the through groove is full, it rotates to the right side, and then by starting the micro air pump, air is pumped into the sealing cover along the air suction pipe. Therefore, the wool collected in the left through groove is sucked, and finally discharged into the collection box through the exhaust pipe, thus achieving the effect of conveniently cleaning the wool on the surface of the woven belt and avoiding the woven belt from being drawn.

[0019] 2. In this weft releasing machine for cleaning the wool on the surface of a woven belt, the lower wedge block drives to squeeze the upper wedge block through the shaft rod, which will cause the swing rod to deflect and swing with the rotating rod as the axis. Then the fixed column is squeezed to compress the torsion spring, and the compressed torsion spring will drive the swing rod to rotate reversely and reset. So the swing rod swings back and forth, which will drive the brush to clean the wool attached to the inner wall of the rotating cylinder back and forth. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the compression spring 656 will drive the sliding plate 652 to reset outward.

[0031] Please refer to Figure 4 , the wool cleaning component 7 includes a rotating cylinder 71 fixedly installed on the back side of the special-shaped plate 62. A shaft rod 72 is fixedly installed at the center inside the rotating cylinder 71. A triangular scraping plate 73 is fixedly installed on the outer side of the rotating cylinder 71. A storage groove 731 is opened inside the triangular scraping plate 73. A through groove 732 is opened on the outer side of the rotating cylinder 71 corresponding to the storage groove 731. By the rotation of the special-shaped plate 62 driving the rotating cylinder 71, the latter group of triangular scraping plates 73 will replace the previous triangular scraping plates 73. Then, when the woven belt is transmitted forward, the wool on the surface of the woven belt will be scraped and cleaned by the triangular scraping plates 73, and the cleaned wool will be collected into the storage groove 731; Four groups of triangular scraping plates 73 are arranged in an array on the outer side of the rotating cylinder 71. A rotating disk 74 is rotatably connected to the inner wall of the rotating cylinder 71, and the rotating disk 74 is sleeved on the outer side of the shaft rod 72. A collection box 75 is fixedly installed at the bottom of the rotating disk 74. An extraction component 76 is arranged on the left side inside the rotating cylinder 71.

Fixed columns 7712 are fixedly installed at both ends of the torsion spring 7711, and the two fixed columns 7712 are respectively located on both sides of the swing rod 773. When the swing rod 773 deflects, it will squeeze the fixed column 7712 to compress the torsion spring 7711, and the compressed torsion spring 7711 will drive the swing rod 773 to rotate reversely and reset, thereby causing the swing rod 773 to swing back and forth, and driving the brush 776 to clean the wool back and forth, improving the cleaning effect.

[0035] Working principle: Please refer to Figure 1-6, first, the webbing is transported and sorted by the releasing roller 3, and then the built-in motor is started to drive the rotating wheel 61 to rotate, which will cause the rotating column 653 to rotate into the sliding groove 64. Then, as the rotating wheel 61 rotates, it will drive the rotating column 653 to squeeze the special-shaped plate 62 along the inner wall of the sliding groove 64, causing the special-shaped plate 62 to drive the rotating cylinder 71 to rotate a quarter of a circle. Therefore, the latter set of triangular scraping plates 73 will replace the previous triangular scraping plates 73. Then, when the webbing is transported forward, the wool on the surface of the webbing will be scraped and cleaned by the triangular scraping plates 73, and the scraped wool will be collected in the storage groove 731;

[0036] Among them, due to the intermittent rotation of the rotating cylinder 71, when the through groove 732 is full, it will rotate to the right side. Then, by starting the micro air pump 761, air will be pumped into the sealing cover 762 along the air extraction pipe 763. Therefore, the wool collected in the left through groove 732 will be sucked, and finally discharged into the collection box 75 through the exhaust pipe 764, so that the wool on the surface of the webbing can be continuously cleaned;

[0037] At the same time, the rotation of the shaft rod 72 will drive the lower wedge block 775 to squeeze the upper wedge block 774, which will cause the swing rod 773 to deflect and swing around the rotating rod 772. At the same time, it will squeeze the fixed column 7712 to compress the torsion spring 7711. Then, the compressed torsion spring 7711 will drive the swing rod 773 to rotate and reset in the reverse direction. Therefore, the swing rod 773 will swing back and forth, which will drive the brush 776 to clean the wool attached to the inner wall of the rotating cylinder 71 back and forth.

[0038] In summary, for the webbing releasing machine for cleaning the wool on the surface of the webbing, due to the intermittent rotation of the rotating cylinder 71, the latter set of triangular scraping plates 73 will replace the previous triangular scraping plates 73. The wool on the surface of the webbing is scraped and cleaned by the triangular scraping plates 73. When the through groove 732 is full of wool, it will rotate to the right side. Then, by starting the micro air pump 761, air will be pumped into the sealing cover 762 along the air extraction pipe 763. Therefore, the wool collected in the left through groove 732 will be sucked, and finally discharged into the collection box 75 through the exhaust pipe 764, so as to achieve the effect of conveniently cleaning the wool on the surface of the webbing and avoiding the webbing from being drawn.

[0039] The rotation of the shaft rod 72 drives the lower wedge block 775 to squeeze the upper wedge block 774, which will cause the swing rod 773 to deflect and swing around the rotating rod 772. Then, it will squeeze the fixed column 7712 to compress the torsion spring 7711. The compressed torsion spring 7711 will drive the swing rod 773 to rotate and reset in the reverse direction, so that the swing rod 773 will swing back and forth, which will drive the brush 776 to clean the wool attached to the inner wall of the rotating cylinder 71 back and forth.
