Detailed Description

In the following description of the present invention, it is understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention and to simplify the description, but not to indicate or imply that the indicated device or element must have a specific direction, be constructed and operated in a specific direction, and thus should not be construed as limiting the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

As shown in fig. 1, 2, 3 and 4, the efficient hemming device for producing the tear-resistant backpack comprises a machine body 1 and a needle 2, wherein a driving rod 3 is arranged in the machine body 1, and the needle 2 is mounted at the bottom of the driving rod 3. The driving rod 3 can move vertically in the machine body 1 and drive the needle 2 to perform sewing work. And a cooling mechanism is arranged in the machine body 1 and comprises a cooling jacket 4, a liquid storage tank 5 and a liquid guide pipe 7. The liquid storage tank 5 is fixedly arranged inside the machine body 1 and extends to the outside of the machine body 1, and cooling liquid for cooling the sewing needle 2 can be stored in the liquid storage tank 5. The liquid storage tank 5 is provided with a liquid feeding hole at a position outside the machine body 1, and an operator can add cooling liquid into the liquid storage tank 5 through the liquid feeding hole. And the liquid feeding hole is also provided with a screw cap 6, and the screw cap 6 can play the roles of sealing the liquid storage tank 5 and preventing dust from entering the liquid storage tank 5.

The cooling jacket 4 is arranged below the liquid storage tank 5, a second sleeve 9 is arranged on the cooling jacket 4, a first sleeve 8 is arranged on the liquid storage tank 5, and the first sleeve 8 is in threaded connection with the second sleeve 9. Therefore, the operator can adjust the distance between the cooling jacket 4 and the liquid storage tank 5 by rotating the second sleeve 9. And the driving rod 3 is sleeved with the cooling jacket 4, and the driving rod 3 penetrates from the top end of the liquid storage tank 5 to the bottom end of the cooling jacket 4. A cooling cavity 10 is arranged in the cooling jacket 4, and two ends of the liquid guide pipe 7 are respectively communicated with the cooling cavity 10 and the liquid storage tank 5. The cooling liquid in the liquid storage tank 5 flows into the cooling chamber 10 along the liquid guide tube 7. When the driving rod 3 carries the needle 2 to move upwards, the needle 2 slides into the cooling cavity 10 and is immersed by the cooling liquid, so that the heat on the needle 2 is quickly conducted and dissipated. And when the machine needle 2 works, the machine needle can be continuously immersed by the cooling liquid, so that the cooling effect is ensured. Thereby make the sewing needle 2 when the car hole, can not scald the fibre of its contact because overheated, prevent the hole increase of the car play to make the knapsack of sewing compact more firm, the intensity of surface fabric can not impaired.
