Description

Technical Field

[0001] The utility model relates to the technical field of fabric production equipment, and particularly relates to a fabric warp knitting machine. Background Art

[0002] Fabric is the material used to make clothing. It can not only interpret the style and characteristics of clothing, but also directly influence the color and shaping performance of clothing. According to the tissue characteristics of the fabric, it can be divided into knitted fabric and woven fabric. Among them, knitted fabric is formed by using knitting needles to form loops of yarn or filament and then stringing the loops together. Due to the loop structure characteristics of knitted fabric, the amount of stored yarn per unit length is relatively large, so most of them have good elasticity. Woven fabric is a fabric formed by interweaving warp yarns and weft yarns perpendicular to each other.

[0003] A warp knitting machine is an important textile machine for producing warp knitted fabrics, which has the advantages of high production efficiency and can quickly weave a large amount of fabrics.

[0004] In the patent document of a mercerized velvet fabric warp knitting machine with the publication number of CN215757883U, it includes a cutting mechanism and a warp knitting machine main body. A cutting mechanism is installed on the right side of the top of the bearing platform. The cutting mechanism is composed of a bearing frame, an electric telescopic rod, a cutting plate, an electric guide rail, a hydraulic rod, a roller and a cutter. An electric guide rail is installed on the top of the bearing frame. The output end of the electric guide rail is installed with an electric telescopic rod. The output end of the electric telescopic rod is installed with a cutter. A hydraulic rod is installed on the left side of the bearing frame. The output end of the hydraulic rod is installed with a roller. The inner side wall of the bearing frame is installed with a cutting plate. By installing a cutting mechanism on the right side of the top of the bearing platform, the cutter can shear the fabric, which is convenient for personnel to use. However, the above patent document still has the following defects in the implementation process:

[0005] When the device cuts the fabric, since the fabric is in an unclamped and fixed state, the fabric is not only prone to movement and wrinkles, resulting in the cutting line deviating from the predetermined trajectory, making the size of the cut fabric inaccurate and the shape irregular. At the same time, due to inaccurate cutting and poor cutting surface quality, a large amount of fabric will become waste, increasing the waste of raw materials and raising the production cost. Therefore, we propose a fabric warp knitting machine to solve the above problems. Summary of the Utility Model

[0006] The main purpose of the utility model is to provide a fabric warp knitting machine, which can effectively solve the above problems.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

Specifically, when the fabric needs to be cut, two electric push rods are opened to drive the telescopic rods to contract, so that the first rotating rod drives the pressing block to move downward, fixing the fabric on the surface of the machine body, making the fabric in a pressed and fixed state during cutting. The fabric will not deviate from the predetermined track of the cutting line, enabling the size of the cut fabric to be more accurate.

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0026] Embodiment 1

[0027] As Figure 1 and Figure 2 shown, a fabric warp knitting machine includes a base 1, a warp knitting support 11 is fixedly connected to the center of the top of the base 1, a machine body 12 is fixedly connected to the top of the base 1, an adjusting component 2 is arranged inside the machine body 12, and a pressing component 3 is arranged inside the machine body 12.

[0028] Specifically, in order to achieve the purpose of preventing the fabric from moving and wrinkling during cutting, which may cause the cutting line to deviate from the predetermined trajectory, referring to Figure 5 and Figure 6 , in this embodiment, the pressing component 3 includes a hollow frame 31, the bottom of the hollow frame 31 is fixedly connected to the top of the machine body 12, two electric push rods 37 are fixedly connected to the top of the hollow frame 31, the two electric push rods 37 are symmetrically arranged with respect to the center of the hollow frame 31, the output end of the electric push rod 37 is fixedly connected to a telescopic rod 38, the end of the telescopic rod 38 far from the electric push rod 37 is fixedly connected to a moving frame 36, and the bottom of the moving frame 36 is slidably connected to a slide rail 35, and the bottom of the slide rail 35 is fixedly connected to the top of the hollow frame 31.

[0029] During the implementation process, turn on the two electric push rods 37 to drive the telescopic rods 38 to contract. During the contraction of the telescopic rods 38, the moving frame 36 will be driven to move towards the center of the hollow frame 31. By setting the slide rail 35, the moving frame is made more stable during the movement.

[0030] Further, referring to Figure 6, in this embodiment, rotating rods II 34 are rotatably connected to both the front and back of the moving frame 36. Rotating rods I 321 are rotatably connected to the bottoms of the two rotating rods II 34. Pressing blocks 33 are rotatably connected to the tops of the two rotating rods I 321. Fixed blocks I 32 are rotatably connected to the sides of the two rotating rods I 321 away from the rotating rods II 34. The ends of the two fixed blocks I 32 close to each other are fixedly connected to the outer surface of the hollow frame 31.

[0031] During the implementation process, when the moving frame 36 moves, it will drive the two rotating rods II 34 to rotate. When the rotating rods II 34 rotate, they will drive the rotating rods I 321 to rotate. When the rotating rods I 321 rotate, they will drive the pressing blocks 33 to move downward, fixing the fabric on the surface of the machine body 12, so that the fabric is in a state of being tightly fixed during cutting. The fabric will not deviate from the predetermined trajectory of the cutting line, making the size of the cut fabric more accurate. At the same time, the quality of the cut surface of the fabric is improved, reducing the probability of the fabric becoming a waste product and lowering the production cost.

[0032] Further, referring to Figure 7 , in this embodiment, a motor 39 is fixedly connected to the right end of the hollow frame 31. A threaded rod 391 is fixedly connected to the output end of the motor 39. A cutting knife 392 is threadedly connected to the outer surface of the threaded rod 391. The outer surface of the top of the cutting knife 392 contacts the inner wall of the hollow frame 31.

[0033] During the implementation process, the motor 39 is turned on to drive the threaded rod 391 to rotate clockwise. When the threaded rod 391 rotates, it will drive the cutting knife 392 to move to the left to cut the fabric. By driving the cutting knife 392 to move through the motor 39, the efficiency of cutting the fabric is improved.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, this embodiment restricts the position of the fabric on the round rod 24.

[0036] Specifically, in order to ensure that the fabric can remain flat during transmission and effectively prevent the fabric from wrinkling and locally deforming, referring to Figure 3 and Figure 4 , in this embodiment, the adjusting assembly 2 includes a bidirectional threaded rod 22. The outer surface of the bidirectional threaded rod 22 is rotatably connected to the inner wall of the machine body 12. A turning handle 21 is fixedly connected to the right end of the bidirectional threaded rod 22. Two moving blocks 241 are fixedly connected to the outer surface of the bidirectional threaded rod 22.

[0037] During the implementation process, according to the width of the knitted fabric, the positions of the two moving blocks 241 are adjusted. First, rotate the handle 21 clockwise to drive the bidirectional threaded rod 22 to rotate. While the bidirectional threaded rod 22 rotates, it will drive the two moving blocks 241 to move closer to each other. By continuously rotating the handle 21 clockwise, the distance between the two moving blocks 241 can be made the same as the width of the knitted fabric.

[0038] Further, referring to Figure 4 , in this embodiment, the two moving blocks 241 are symmetrically arranged with the center of the machine body 12 as the symmetry center. A square groove one is opened at the center of the moving block 241. A fixing rod 242 is fixedly connected to the inner wall of the square groove one. A slider 244 is slidably connected to the outer surface of the fixing rod 242. A spring 243 is sleeved on the outer surface of the fixing rod 242. The bottom of the spring 243 is fixedly connected to the inner wall of the bottom of the square groove one. The top of the spring 243 is fixedly connected to the bottom of the slider 244. One end of the slider 244 close to the center of the machine body 12 is fixedly connected to a rotating rod 245.

[0039] During the implementation process, one end of the knitted fabric after knitting is passed through between the round rod 24 and the rotating rod 245. Since the fabric has a certain thickness, when the fabric is between the round rod 24 and the moving block 241, it will push the slider 244 to move downward on the outer surface of the fixing rod 242 through the rotating rod 245. While the slider 244 moves downward, it will cause the spring 243 to deform. The deformed spring 243 will generate an upward elastic force, enabling the rotating rod 245 to clamp the fabric between the round rod 24 and the rotating rod 245, so that the fabric can be restricted to be conveyed within the length of the conveying roller with the same width, ensuring that the fabric can remain flat during the conveying process, effectively preventing the fabric from wrinkling and local deformation, reducing production interruptions and adjustment time caused by fabric conveying problems, and thus improving the overall production efficiency.

[0040] Further, referring to Figure 3 , in this embodiment, a round rod 24 is slidably connected to the inner walls of the two moving blocks 241 together. Support rods 23 are rotatably connected to the outer surfaces of the left and right sides of the round rod 24. The backs of the two support rods 23 are fixedly connected to the outer surface of the machine body 12.

[0041] During the implementation process, when the fabric is being conveyed, the round rod 24 will rotate along with the conveyance of the fabric. Through cooperation with the rotating rod 245, the phenomenon of the fabric shifting during conveyance can be avoided.

[0042] The lengths of the two rotating rods 245 can be customized according to the requirements of the actual production process to ensure the stability of the fabric during the implementation process and prevent it from falling or wrinkling.

[0043] The working principle of the present utility model is as follows: According to the width of the knitted fabric, the positions of the two moving blocks 241 are adjusted. First, rotate the handle 21 clockwise to drive the bidirectional threaded rod 22 to rotate. While the bidirectional threaded rod 22 rotates, it will drive the two moving blocks 241 to move closer to each other. By continuously rotating the handle 21 clockwise, the distance between the two moving blocks 241 can be made the same as the width of the knitted fabric. One end of the knitted fabric after knitting is passed between the round rod 24 and the rotating rod 245. Since the fabric has a certain thickness, when the fabric is between the round rod 24 and the moving block 241, it will push the slider 244 to move downward on the outer surface of the fixed rod 242 through the rotating rod 245. When the slider 244 moves downward, it will cause the spring 243 to deform. The deformed spring 243 will generate an upward elastic force, enabling the rotating rod 245 to clamp the fabric between the round rod 24 and the rotating rod 245, so that the fabric can be restricted to be conveyed within the length of the conveyor roller with the same width, ensuring that the fabric can remain flat during the transmission process, effectively preventing the fabric from wrinkling and locally deforming, reducing production interruptions and adjustment time caused by fabric transmission problems, and thus improving the overall production efficiency. When the fabric needs to be cut, two electric push rods 37 are opened to drive the telescopic rods 38 to contract. During the contraction of the telescopic rods 38, it will drive the moving frame 36 to move towards the center of the hollow frame 31. During the movement of the moving frame 36, it will drive the two second rotating rods 34 to rotate. While the second rotating rods 34 rotate, they will drive the first rotating rod 321 to rotate. The rotation of the first rotating rod 321 will drive the pressing block 33 to move downward to fix the fabric on the surface of the machine body 12. After the fabric is fixed, the motor 39 is turned on to drive the threaded rod 391 to rotate clockwise. While the threaded rod 391 rotates, it will drive the cutting knife 392 to move to the left to cut the fabric, so that the fabric is in a tightly fixed state during cutting, and the fabric will not deviate from the predetermined trajectory of the cutting line, making the size of the cut fabric more accurate. At the same time, the quality of the fabric cutting surface is improved, reducing the probability of the fabric becoming a waste product and lowering the production cost.

[0044] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
