[0050] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0051] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.
[0052] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.
[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0054] It should be noted that during the edge cutting process, the warp-knitted fabric 8 is conveyed by multiple rollers; the warp-knitted fabric 8 is wound on multiple rollers and can move at a uniform speed with multiple rollers, and can remain taut throughout the process, which facilitates the cutting of the edge by the cutter.
[0055] When the current selvage cutting machine processes the warp-knitted fabric 8, the existing rotating blade first causes the fibers on the warp-knitted fabric 8 to deform under downward pressure when it comes into contact with the surface of the warp-knitted fabric 8, and then it is cut by the blade. During this process, the fibers on the warp-knitted fabric 8 are prone to large deformation when squeezed by the blade, which in turn causes uneven selvage cuts and structural damage to the warp-knitted fabric 8, affecting the production quality of the warp-knitted fabric 8.
[0056] Please refer to the following: Figures 1 to 4 The selvage cutting assembly provided in this application will now be described. The selvage cutting assembly includes a support 1, two rotating blades 2, and a drive assembly.
[0057] The bracket 1 is made of metal and is used to install on the aforementioned warp-knitted fabric 8 roller conveyor. The metal bracket 1 can also absorb static electricity on the warp-knitted fabric 8 and transmit it to the ground through the grounding wire, so as to avoid static electricity attracting the cut fabric edge and causing interference.
[0058] Both rotating blades 2 are rotatably connected to the bracket 1 and are axially fitted together, or the two rotating blades 2 are close to each other with only a slight distance between them; both rotating blades 2 have multiple cutting edges for contacting the warp-knitted fabric 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 form a notch for the warp-knitted fabric 8 to enter. When the warp-knitted fabric 8 moves with the roller conveyor, the warp-knitted fabric 8 can enter one of the notches on the two rotating blades 2 for cutting.
[0059] Each rotating blade 2 has a rotating shaft coaxially connected to the side facing away from the other rotating blade 2, and each rotating shaft is rotatably connected to the bracket 1.
[0060] The drive assembly is connected to the two rotating blades 2 respectively, and is used to drive the rotating shaft connected to the two rotating blades 2 to rotate, so as to drive the two rotating blades 2 to rotate synchronously. The drive assembly can use two motors to drive the two rotating blades 2 respectively, and the two motors rotate in opposite directions. Alternatively, the drive assembly can use one motor to drive the two rotating blades 2 simultaneously.
[0061] The two rotating blades 2 are used to contact the upper and lower surfaces of the warp-knitted fabric 8 respectively to cut the warp-knitted fabric 8.
[0062] In this embodiment, by mounting the bracket 1 on a horizontal workbench and activating the drive assembly to simultaneously drive the two rotating blades 2 to rotate, since the two rotating blades 2 rotate in opposite directions, when the warp-knitted fabric 8 is fed into the cutting area of the rotating blades 2, the two rotating blades 2 are adapted to contact the upper and lower surfaces of the warp-knitted fabric 8 respectively, and simultaneously cut the warp-knitted fabric 8; during this process, the fibers on the warp-knitted fabric 8 are subjected to the squeezing force from the two rotating blades 2, and the two squeezing forces can cancel each other out.
[0063] Compared with the prior art, the selvage cutting assembly provided in this application embodiment can make synchronous contact with the upper and lower surfaces of the warp-knitted fabric 8 with the two rotating blades 2, and the forces on the upper and lower surfaces of the warp-knitted fabric 8 cancel each other out, thus avoiding the deformation of the fibers on the warp-knitted fabric 8, thereby making the selvage cut of the warp-knitted fabric 8 tighter and neater, and improving the production quality of the warp-knitted fabric 8.
[0064] In some embodiments, please refer to the following: Figures 2 to 4 As a specific embodiment of the fabric edge cutting component provided by the present invention, the driving component includes two sets of first transmission components 3 and a drive motor 5.
[0065] Two sets of first transmission components 3 are respectively mounted on the bracket 1; the two sets of first transmission components 3 are connected to the two rotating blades 2 in a one-to-one transmission connection, and each set of first transmission components 3 is connected to the rotating shaft on the corresponding rotating blade 2.
[0066] The drive motor 5 is mounted on the bracket 1. The output end of the drive motor 5 is connected to the input end of the two sets of first transmission components 3 through the reversing mechanism 4, so that the output ends of the two sets of first transmission components 3 are in opposite directions.
[0067] By adopting the above technical solution, using the drive motor 5 and the reversing mechanism 4, it is possible to use one motor to drive two rotating blades 2 to rotate, and the two rotating blades 2 rotate in opposite directions. This reversing structure reduces the number of motors used and lowers the overall cost of the equipment.
[0068] In some embodiments, please refer to the following: Figures 2 to 4 As a specific embodiment of the fabric edge cutting component provided by the present invention, the reversing mechanism 4 includes a second transmission component 41, a first gear 42, and a second gear 43.
[0069] The second transmission component 41 is connected to the output end of the drive motor 5; the second transmission component 41 can be a synchronous belt drive mechanism, a chain drive mechanism or a belt drive mechanism.
[0070] The first gear 42 is rotatably connected to the bracket 1, and its rotation axis is parallel to the rotation axis of the rotating blade 2. One end of the first gear 42 is connected to the second transmission component 41, which is used to transmit the rotation of the drive motor 5 to the first gear 42 so as to drive the first gear 42 to rotate synchronously. The other end of the first gear 42 is connected to the corresponding first transmission component 3, which is used to transmit the rotation of the first gear 42 to the rotating blade 2 so as to drive the rotating blade 2 to rotate synchronously.
[0071] The second gear 43 is rotatably connected to the bracket 1 and meshes with the first gear 42. The first gear 42 and the second gear 43 mesh with each other and rotate in opposite directions. One end of each gear is connected to the corresponding first transmission member 3. The first transmission member 3 is used to transmit the rotation opposite to that of the first gear 42 to another rotating blade 2.
[0072] By adopting the above technical solution, the rotation of the drive motor 5 is converted into two rotations in opposite directions by utilizing the meshing structure of the first gear 42 and the second gear 43. The mechanical structure realizes the reversal, and the structure is simple, reliable, and easy to maintain and replace.
[0073] In some embodiments, please refer to the following: Figures 2 to 5 As a specific embodiment of the fabric edge cutting assembly provided by the present invention, the first transmission component 3 includes a first synchronous pulley 32, a second synchronous pulley 31 and a transmission belt 33.
[0074] The first synchronous pulley 32 is connected to the shaft of the corresponding rotating blade 2. The connection between the first synchronous pulley 32 and the shaft is a key and keyway connection to avoid relative rotation between the first synchronous pulley 32 and the shaft.
[0075] The second synchronous pulley 31 is connected to the shaft of the corresponding first gear 42 / second gear 43. The shafts of the second synchronous pulley 31 and the first gear 42 / second gear 43 are connected by a key and keyway to avoid relative rotation between the second synchronous pulley 31 and the first gear 42 / second gear 43.
[0076] The specific number of teeth on the first synchronous pulley 32 and the second synchronous pulley 31 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.
[0077] The transmission belt 33 is wrapped around the first synchronous pulley 32 and the second synchronous pulley 31. The inner wall of the synchronous belt has a plurality of toothed protrusions that are adapted to the tooth profile of the first synchronous pulley 32 and the second synchronous pulley 31, so as to enable the first synchronous pulley 32 and the second synchronous pulley 31 to rotate synchronously and avoid belt slippage affecting product quality.
[0078] In some embodiments, please refer to the following: Figures 1 to 3 As a specific embodiment of the fabric edge cutting assembly provided by the present invention, the bracket 1 has two parallel side plates 11; wherein, the two rotating blades 2, the first gear 42 and the second gear 43 are all located between the two side plates 11; the second transmission member 41 is disposed on the outer side of one of the side plates 11, and the two sets of first transmission members 3 are respectively disposed on the outer side of the two side plates 11.
[0079] 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 component 3 and the second transmission component 41, making the layout more reasonable and ensuring that each part is not disturbed, which is convenient for later maintenance and replacement.
[0080] In some embodiments, please refer to the following: Figures 2 to 5 As a specific embodiment of the fabric edge cutting assembly provided by the present invention, each side plate 11 has a guide plate 12; one end of the guide plate 12 is connected to the side plate 11, and the other end has a bent portion that is inclined toward the rotating blade 2. The bent portion is used to separate the fabric from the rotating blade 2; wherein, the side of the bent portion facing away from the rotating blade 2 also has an extension plate, which can cover the first transmission member 3 to prevent the fabric from being rolled in.
[0081] 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 component 3, allowing the cut fabric to move to both sides along the guide plate 12, preventing the fabric from getting caught in the rotating mechanism, avoiding jamming of the equipment, and improving the overall safety and stability of the equipment.
[0082] In some embodiments, please refer to the following: Figure 5 and Figure 6 As a specific embodiment of the fabric edge cutting component provided by the present invention, the two rotating blades 2 are connected by a fitting structure 6.
[0083] Due to friction, direct contact rotation generates a lot of heat, which can deform the rotating blade 2 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 two rotating blades 2 in close contact, and avoid heat accumulation.
[0084] In some embodiments, please refer to the following: Figure 5 and Figure 6 As a specific embodiment of the fabric edge cutting component provided by the present invention, the fitting structure 6 includes a groove 61 and a boss 62.
[0085] The groove 61 is coaxially formed on one of the rotating blades 2.
[0086] The boss 62 is coaxially mounted on another rotating blade 2. When the two rotating blades 2 are in contact with each other, the boss 62 is adapted to be embedded in the groove 61, and a rotating bearing 63 is provided between the boss 62 and the groove 61. By adding lubricating oil to the rotating bearing 63, the friction between the two rotating blades 2 when they rotate relative to each other can be further reduced.
[0087] By adopting the above technical solution, direct contact and mutual rotation of the two rotating blades 2 can be avoided. The cooperation between the boss 62 and the groove 61 also improves the concentricity of the two rotating blades 2 when they rotate, and the two rotating blades 2 are less likely to deviate from each other in the radial direction.
[0088] In some embodiments, please refer to the following: Figures 1 to 4 As a specific embodiment of the fabric edge cutting assembly provided by the present invention, each rotating blade 2 includes a plurality of cutting blades spaced apart along its own circumference. The cutting blades on the two rotating blades 2 have opposite cutting directions, and the cutting blades form a bevel. The bevel is inclined toward the other rotating blade 2, and the two corresponding cutting blades together form a scissor structure. When the two rotating blades 2 are in contact with each other, the cutting blades on the two rotating blades 2 are in contact with each other.
[0089] Each cutting blade features an arc-shaped structure, which reduces the area in contact with the warp-knitted fabric 8, thereby increasing the pressure per unit area and improving the cutting effect.
[0090] By adopting the above technical solution, when the warp-knitted fabric 8 is fed into the cutting area of the two rotating blades 2, one set of cutting blades on the two rotating blades 2 is adapted to contact the upper and lower surfaces of the warp-knitted fabric 8 respectively, and cut the warp-knitted fabric 8 simultaneously; during this process, the fibers on the warp-knitted fabric 8 are subjected to the squeezing force from the two cutting blades, and the two squeezing forces can cancel each other out, avoiding deformation of the fibers on the warp-knitted fabric 8 and improving the cutting effect.
[0091] Please see Figure 1 The technical solution adopted in this application also provides an integrated fabric edge cutting machine, including two sets of fabric edge cutting components as described in any of the above and a synchronous drive mechanism 7.
[0092] The integrated selvage cutting machine has a worktable for supporting the warp-knitted fabric 8, which can move on the worktable with the roller conveyor mechanism.
[0093] Two sets of selvage cutting components are located on both sides of the workbench and are used to cut off the two selvages of the warp-knitted fabric 8 respectively.
[0094] The synchronous drive mechanism 7 is connected to two sets of fabric edge cutting assemblies, and is used to make the two sets of fabric edge cutting assemblies move towards or away from each other. The synchronous drive mechanism 7 can adopt a drive structure of a double-ended screw and two threaded sleeves. The double-ended screw has two threaded parts with opposite thread directions and is connected to a motor. The two threaded sleeves are respectively connected to the two sets of fabric edge cutting assemblies, and the two threaded sleeves are respectively threadedly connected to the two threaded parts. By controlling the motor to rotate forward or backward, the two sets of fabric edge cutting assemblies can move synchronously towards or away from each other.
[0095] By adopting the above technical solution, the staff can adjust the width of the two selvages of the warp-knitted fabric 8 to be cut off by adjusting the synchronous drive mechanism 7, thereby improving the applicability of the equipment.
[0096] Compared with the prior art, the integrated selvage cutting machine provided in this application embodiment can simultaneously cut the selvage of the two selvages of the warp-knitted fabric 8 with two sets of selvage cutting components. Moreover, the operator can adjust the required cutting width of the selvages on both sides of the warp-knitted fabric 8 by adjusting the synchronous drive mechanism 7. It has the advantages of simple operation and easy maintenance.
[0097] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
