In the production process of warp knitted fabric, edge trimming is generally required to ensure continuous weaving and high-speed weaving requirements.

[0003] At present, warp knitted fabrics are generally cut using a selvedge cutting machine. The cutter in the selvedge cutting machine is a rotary cutter. During the process of conveying the warp knitted fabric into the selvedge cutting machine, the high-speed rotating rotary cutter contacts the surface of the warp knitted fabric, thereby cutting off the selvedge of the warp knitted fabric.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0023] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] It should be noted that during the fabric edge cutting process, the warp knitted fabric 8 is transported by multiple round rollers; the warp knitted fabric 8 is wound around multiple round rollers and can move at a constant speed with the multiple round rollers and can remain taut throughout the process, making it easier for the cutter to cut the fabric edge.

[0026] When the current fabric edge cutting machine processes the warp knitted fabric 8, the existing rotary tool, when in contact with the surface of the warp knitted fabric 8, will first cause the fibers on the warp knitted fabric 8 to be deformed by the downward pressure, and then be cut off by the blade of the rotary tool. During this process, the fibers on the warp knitted fabric 8 are easily greatly deformed when squeezed by the tool, thereby causing uneven fabric edge cuts and structural damage of the warp knitted fabric 8, affecting the production quality of the warp knitted fabric 8.

[0027] Please also read Figures 1 to 4 Now, the cloth edge cutting assembly provided by the present application is described. The cloth edge cutting assembly comprises a bracket 1, two rotating blades 2 and a driving assembly.

[0028] The bracket 1 is made of metal material and is used to be installed on the above-mentioned round roller conveying device for the warp knitted fabric 8; the bracket 1 made of metal material can also absorb the static electricity on the warp knitted fabric 8 and transmit it to the ground through the grounding wire to avoid static electricity attracting the cut fabric edges and causing interference.

[0029] The two rotating blades 2 are both rotatably connected to the bracket 1 and are axially fitted together, or the two rotating blades 2 are closely arranged with only a slight distance between them; the two rotating blades 2 are each provided with a plurality of cutting edges for connecting with the warp knitted cloth 8, and the two rotating blades 2 rotate in opposite directions; the two rotating blades 2 rotate synchronously, and the two corresponding cutting edges on the two rotating blades 2 mutually form a gap for the warp knitted cloth 8 to enter, and when the warp knitted cloth 8 moves with the round roller conveying device, the warp knitted cloth 8 can enter one of the gaps on the two rotating blades 2 for cutting.

[0030] A rotating shaft is coaxially connected to a side of each rotating blade 2 facing away from the other rotating blade 2 , and each rotating shaft is rotatably connected to the bracket 1 .

[0031] The driving assembly is respectively connected to the two rotating blades 2 for driving the rotating shafts connected to the two rotating blades 2 to rotate, so as to drive the two rotating blades 2 to rotate synchronously; the driving assembly can use two motors to drive the two rotating blades 2 respectively, and the rotation directions of the two motors are opposite; the driving assembly can also use one motor to drive the two rotating blades 2 at the same time.

[0032] The two rotating blades 2 are respectively used to contact the upper and lower surfaces of the warp knitted fabric 8 to cut the warp knitted fabric 8 .

[0033] In the embodiment of the present application, the bracket 1 is installed on a horizontal workbench and the driving assembly is turned on to drive the two rotating blades 2 to rotate at the same time. Since the rotation directions of the two rotating blades 2 are opposite, when the warp knitted cloth 8 is fed into the cutting area of ​​the rotating blades 2, the two rotating blades 2 are suitable for respectively connecting with the upper and lower surfaces of the warp knitted cloth 8 to cut the warp knitted cloth 8 synchronously; in this process, the fibers on the warp knitted cloth 8 are subjected to the extrusion pressure from the two rotating blades 2, and the two extrusion pressures can offset each other.

[0034] Compared with the prior art, the cloth edge cutting assembly provided in the embodiment of the present application has two rotating blades 2 that can be synchronously connected with the upper and lower surfaces of the warp knitted cloth 8, and the forces on the upper and lower surfaces of the warp knitted cloth 8 offset each other, thereby avoiding deformation of the fibers on the warp knitted cloth 8, thereby making the cloth edge cuts of the warp knitted cloth 8 tighter and neater, and improving the production quality of the warp knitted cloth 8.

[0035] In some embodiments, please refer to Figures 2 to 4 As a specific embodiment of the cloth edge cutting assembly provided by the present invention, the driving assembly includes two groups of first transmission components 3 and a driving motor 5.

[0036] Two groups of first transmission components 3 are respectively arranged on the bracket 1; the two groups of first transmission components 3 are transmission-connected with the two rotating blades 2 in a one-to-one correspondence, and each group of first transmission components 3 is connected to the rotating shaft on the corresponding rotating blade 2.

[0037] The driving motor 5 is arranged on the bracket 1 , and the output end of the driving motor 5 is connected to the input ends of the two groups of first transmission components 3 through the reversing mechanism 4 , so that the output ends of the two groups of first transmission components 3 have opposite transmission directions.

[0038] By adopting the above technical solution, using the driving motor 5 and the reversing mechanism 4, it is possible to use one motor to drive the two rotating blades 2 to rotate, and the rotation directions of the two rotating blades 2 are opposite. The setting of the reversing structure reduces the number of motors used and reduces the overall cost of the equipment.

The first gear 42 and the second gear 43 that mesh with each other rotate in opposite directions, and one end is connected to the corresponding first transmission member 3. The first transmission member 3 is used to transmit the rotation opposite to the rotation direction of the first gear 42 to another rotating blade 2.

[0043] By adopting the above technical solution, the first gear 42 and the second gear 43 are meshed with each other to realize the conversion of the rotation of the drive motor 5 into two rotations in opposite directions, and the reversal is realized by the mechanical structure. The structure is simple, reliable and easy to repair and replace.

[0044] In some embodiments, please refer to Figures 2 to 5 As a specific embodiment of the cloth edge cutting assembly provided by the present invention, the first transmission member 3 includes a first synchronous wheel 31, a second synchronous wheel 32 and a transmission belt 33.

[0045] The first synchronous wheel 31 is connected to the rotating shaft of the corresponding rotating blade 2, and the first synchronous wheel 31 and the rotating shaft are connected in the form of a key and a keyway to avoid relative rotation between the first synchronous wheel 31 and the rotating shaft.

[0046] The second synchronous wheel 32 is connected to the rotating shaft of the corresponding first gear 42 / second gear 43, and the rotating shaft of the second synchronous wheel 32 and the first gear 42 / second gear 43 adopts a key and keyway connection form to avoid relative rotation between the second synchronous wheel 32 and the first gear 42 / second gear 43.

[0047] The specific number of teeth of the first synchronous wheel 31 and the second synchronous wheel 32 can be adjusted by the staff according to the actual situation on site so that the two rotating blades 2 can obtain the most suitable rotation speed.

[0048] The transmission belt 33 is wrapped around the first synchronous wheel 31 and the second synchronous wheel 32. The inner wall of the synchronous belt has a plurality of tooth-shaped protrusions that match the tooth shapes on the first synchronous wheel 31 and the second synchronous wheel 32, so as to make the first synchronous wheel 31 and the second synchronous wheel 32 rotate synchronously and avoid belt slippage affecting product quality.

[0049] In some embodiments, please refer to Figures 1 to 3 As a specific embodiment of the cloth edge cutting assembly provided by the present invention, the bracket 1 has two parallel side panels 11; wherein the two rotating blades 2, the first gear 42 and the second gear 43 are all located between the two side panels 11; the second transmission member 41 is arranged on the outer side surface of one of the side panels 11, and the two groups of first transmission members 3 are respectively arranged on the outer side surfaces of the two side panels 11.

[0050] By adopting the above technical solution, the bracket 1 can separate the two rotating blades 2, the first gear 42, the second gear 43, the first transmission member 3 and the second transmission member 41, the layout is more reasonable, and each part is not interfered with, which is easy to repair and replace later.

[0052] By adopting the above technical solution, the guide plate 12 can block the rotating shaft of the rotating blade 2 and the rotating part of the first transmission member 3, so that the cut cloth can move to both sides along the guide plate 12, avoiding the cloth from being rolled into the rotating mechanism, avoiding the equipment from getting stuck, and improving the overall safety and stability of the equipment.

[0053] In some embodiments, please refer to Figure 5 and Figure 6 As a specific embodiment of the cloth edge cutting assembly provided by the present invention, the two rotating blades 2 are connected via a mosaic structure 6.

[0054] Due to friction, direct contact rotation will generate a lot of heat, which will cause the rotating blade 2 to deform and affect the cutting effect. By adopting the above technical solution, the interlocking mechanism can avoid direct contact rotation of the two rotating blades 2, improve the stability of the fitting rotation of the two rotating blades 2, and avoid heat accumulation.
