Description

Technical Field

[0001] The utility model belongs to the technical field of knitted cotton production, in particular to a needle loom edge trimming device. Background Art

[0002] Knitted cotton, also known as non-woven fabric or needle-punched cotton, is made of polyester fiber and polyester fiber. It has different textures and hardness depending on the material and production process. It is usually made using a needle-punching machine.

[0003] The needle loom is a blanket-making device that compacts and needles a refractory fiber blanket of a certain thickness to weave it into a refractory fiber blanket. Its structure includes a needle plate, needles, and a pressing plate structure. The needles are injected into the needle plate through the pressing edge structure to drive the silk thread to produce knitted cotton.

[0004] When the existing needle loom machine trims the needle-punched cotton produced, the knitted cotton has a soft texture, which causes the cloth to curl during trimming. This will cause the knitted cotton surface to deform and the trimming area to be irregular. Therefore, a needle loom trimming device is proposed to address the above problems. Utility Model Content

The No. 1 rotating rod 15 is provided with a No. 2 rotating rod 18 on the side away from the circular saw 33. The No. 2 rotating rod 18 is fixed to the outside of the bearing support 10 by a No. 1 bearing 19. The other ends of the No. 1 rotating rod 15 and the No. 2 rotating rod 18 are respectively connected to both sides of the No. 2 fixing plate 22 by the No. 2 bearing 16 and the No. 3 bearing 11. The top side of the No. 2 fixing plate 22 is provided with a No. 4 bearing 23, and the No. 4 bearing 23 is connected to the No. 3 rotating rod 24. , the other end of the No. 3 rotating rod 24 is provided with a No. 5 bearing 25, the outside of the No. 5 bearing 25 is provided with a wheel 26, the top of the wheel 26 is provided with a No. 3 fixing plate 27, one side of the No. 3 fixing plate 27 is provided with a spring 28, the other end of the spring 28 is fixed to the bottom end of the No. 2 fixing plate 22; when performing the edge trimming work, the operator starts the No. 1 motor 6 and toggles the switch 21 of the No. 2 motor 20. At this time, the No. 1 motor 6 drives the stretching rod 7 to lower the No. 1 fixing plate 8. At this time, the support columns 9 fixed around the No. 1 fixing plate 8 push the bearing support The column 10 is driven by the bearing support 10 to lower the circular saw 33. When the wheels 26 at the four corners of the circular saw 33 contact the conveyor belt 3, the wheels are lifted by the conveyor belt 3, thereby driving the third rotating rod 24, and the third rotating rod 24 drives the second fixed plate 22. Due to the displacement of the second fixed plate 22, the first rotating rod 15 and the second rotating rod 18 are driven to move. Due to the positional structural relationship between the first rotating rod 15 and the second rotating rod 18, the wheel 26 is pushed forward by them and pulled by the spring 28 above the wheel 26, thereby making the wheel close to the conveyor belt.

[0021] A protective tube 17 is welded to the outside of the circular saw housing 32, and the top of the protective tube 17 is connected to the No. 2 motor 20. A switch 21 is provided on one side of the No. 2 motor 20. The bottom output end of the No. 2 motor 20 is connected to the driving rod 29, and a driving gear 30 is welded to the bottom end of the driving rod 29. The driving gear 30 is meshed and connected with a transmission gear column 31, and the other end of the transmission gear column 31 passes through the circular saw housing 32 and is fixedly connected to the circular saw 33; the No. 1 rotating rod and the No. 2 rotating rod are mirror-imaged with the same structure corresponding to the No. 2 fixed plate. When the No. 2 motor 21 is started, the driving rod 29 drives the driving gear 30 to rotate, and thereby drives the transmission gear column 31 to rotate, thereby driving the circular saw 33. At this time, the stretching rod 7 brings the circular saw 33 to the conveyor belt 3, and the circular saw 33 passes through the conveyor belt 3 and enters the incision 5 to trim the knitted cloth.

[0022] Working principle: When trimming, the operator starts the No. 1 motor 6 and turns the switch 21 of the No. 2 motor 20. At this time, the No. 1 motor 6 drives the stretching rod 7 to lower the No. 1 fixed plate 8. At this time, the support column 9 fixed around the No. 1 fixed plate 8 pushes the bearing support 10, and the bearing support 10 drives the circular saw 33 to descend; when the No. 2 motor 21 is started, the driving rod 29 drives the driving gear 30 to rotate, and thereby drives the transmission gear column 31 to rotate, thereby driving the circular saw 33. At this time, the stretching rod 7 brings the circular saw 33 to the conveyor belt 3, and the circular saw 33 is moved to the conveyor belt 3. The saw 33 passes through the conveyor belt 3 and enters the incision 5, thereby cutting the edge of the knitted cloth. When the wheels 26 located at the four corners of the circular saw 33 touch the conveyor belt 3, the wheels are lifted up by the conveyor belt 3, thereby driving the No. 3 rotating rod 24, and the No. 3 rotating rod 24 drives the No. 2 fixed plate 22. Due to the displacement of the No. 2 fixed plate 22, the No. 1 rotating rod 15 and the No. 2 rotating rod 18 are driven to move. Due to the positional structural relationship between the No. 1 rotating rod 15 and the No. 2 rotating rod 18, the wheel 26 is pushed forward by them and pulled by the spring 28 above the wheel 26, thereby making the wheel close to the conveyor belt.
