DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1-Figure 5 As shown, a cloth cutting device of a warp knitting machine of the utility model comprises a table top 18, a shell 3 is fixedly connected to the upper outer portion of the table top 18, a first slider 8 is penetrated through and slidably connected to the top front portion of the shell 3, a second cutting wire 21 is penetrated through and slidably connected to the bottom rear portion of the first slider 8, a second electric push rod 14 is fixedly connected to the top of the first slider 8, and the output end of the second electric push rod 14 is penetrated through and fixedly connected to the second cutting wire 21, a laser lamp 10 is fixedly connected to the bottom front portion of the first slider 8, two first limiting rods 2 are penetrated through and slidably connected to the top rear side of the shell 3, a heating plate 20 is fixedly connected between the bottoms of the first limiting rods 2, and a first cutting wire 16 is fixedly connected to the bottom of the heating plate 20.

[0027] During operation, when it is necessary to start cutting the cloth, the cloth is firstly cut longitudinally by the second cutting wire 21 , and when the cutting length is sufficient, the cloth is then cut longitudinally by the first cutting wire 16 .

[0028] Further, such as Figure 4As shown, a threaded rod 7 penetrates and is threadedly connected to the middle part of the right side of the first slider 8, and the threaded rod 7 penetrates and is rotatably connected to the outer shell 3. A second limit rod 19 penetrates and is slidably connected to the front right side of the first slider 8, and the second limit rod 19 is fixedly connected to the outer shell 3. A drive motor 6 is fixedly connected to the front right side of the outer shell 3, and the output end of the drive motor 6 penetrates and is fixedly connected to the threaded rod 7.

[0029] During operation, the threaded rod 7 is driven to rotate by the driving motor 6, and then the first slider 8 is moved left and right in cooperation with the first slider 8. Under the action of the second limiting rod 19, the movement of the first slider 8 is more stable.

[0030] Further, such as Figure 3 As shown, a second slider 9 is fixedly connected to the top front of the laser lamp 10 , a third limiting rod 12 passes through and is slidably connected to the middle of the right side of the second slider 9 , and the third limiting rod 12 is fixedly connected to the housing 3 .

[0031] During operation, the cooperation between the second slider 9 and the third limiting rod 12 increases the stability of the movement of the laser lamp 10 and prevents it from falling.

[0032] Further, such as Figure 3 As shown, a first electric push rod 1 is arranged between the first limiting rods 2 , the first electric push rod 1 is fixedly connected to the housing 3 , and an output end thereof passes through and is fixedly connected to the heating plate 20 .

[0033] During operation, the heating plate 20 is driven to move up and down by the first electric push rod 1 .

[0034] Further, such as Figure 1 As shown, two square grooves 11 are opened on the top of the table 18, and the two square grooves 11 correspond to the second cutting wire 21 and the first cutting wire 16 respectively.

[0035] During operation, the second cutting wire 21 and the first cutting wire 16 can extend into the square groove 11 to cut the fabric more decisively and avoid adhesion.

[0036] Further, such as Figure 5 As shown, evenly distributed air inlet holes 17 are opened on the top of the table 18 , and two fans 15 are passed through and fixedly connected to the right side of the table 18 , and the fans 15 correspond to the air inlet holes 17 .

[0037] During operation, the negative pressure generated around the air inlet 17 exerts a certain binding force on the fabric, making it fit the table top 18 more closely, and the air inside the table top 18 is sucked out to the outside through the fan 15 .

[0038] Further, such as Figure 5As shown, pressure rollers 5 are fixedly connected to both the front and rear sides of the table top 18 , and the pressure rollers 5 correspond to the table top 18 , and support feet 4 are fixedly connected to the four corners of the bottom of the table top 18 .

[0039] During operation, the position and height of the cloth are stabilized by the pressing roller 5 , and the equipment is supported by the supporting feet 4 .

[0040] Further, such as Figure 1 As shown, a scale 13 is provided on the front side of the top of the table 18 , and the scale 13 corresponds to the laser lamp 10 .

[0041] During operation, the cutting position that cannot be determined is determined by comparing the scale 13 and the laser light 10 with each other.

[0042] Working principle: When it is necessary to start cutting the cloth, first turn on the laser light 10 and the driving motor 6, and the driving motor 6 drives the threaded rod 7 to rotate, and then drives the first slider 8 to move left and right on the housing 3, and then cooperates with the laser light 10 and the scale 13 to determine the required cutting position, and then pass the cloth through the inside of the pressure roller 5 on the side away from the first cutting wire 16, and then pass the front end of the cloth through the pressure roller 5 on the other end, and then fix the front end of the cloth on the winding roller, and then drive the cloth to move through the winding roller, and at the same time turn on the second electric push rod 14, the second cutting wire 21 and the fan 15, and drive the cloth to move through the second electric push rod 14. The second cutting wire 21 is driven to move downward, and the second cutting wire 21 reaching a predetermined temperature cuts the cloth longitudinally, and the air flow inside the table 18 is driven by the fan 15, so that the air is discharged and a certain negative pressure is generated around the air inlet 17, and the cloth is made to fit the table 18 by the atmospheric pressure, so that the cut cloth is more regular. When it is no longer necessary to cut the cloth, the first electric push rod 1 and the heating plate 20 are started, the first cutting wire 16 is heated by the heating plate 20, and then the heating plate 20 and the first cutting wire 16 are driven downward by the first electric push rod 1 to cut the cloth transversely.

[0043] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
