Description

Technical Field

[0001] The utility model relates to the technical field of fabric cutting, and particularly relates to a cutting mechanism for non-woven fabric clothing fabrics. Background Art

[0002] Non-woven fabric, also known as non-woven cloth, has no warp and weft threads, is very convenient for cutting and sewing, and is light in weight and easy to shape, so it is deeply loved by handicraft enthusiasts. Clothing is made of fabrics, which are the materials used to make clothing. Clothing made of non-woven fabric has the excellent characteristics of non-woven fabric and is one of the preferred materials in the current clothing industry. When making clothing with non-woven fabric, it is necessary to cut the non-woven fabric into specific shapes required for making clothing. Therefore, an auxiliary processing system for non-woven fabric clothing fabrics is proposed to meet the needs of making clothing with non-woven fabric.

[0003] The utility model patent with the patent authorization announcement number CN 221255020 U discloses a device for cutting a fixed length of clothing production fabric, including a cutting main body. The cutting main body includes a workbench and a frame. A clamping mechanism and a cutting mechanism are arranged above the workbench, and a feeding mechanism is arranged in front of the frame. The clamping mechanism includes a clamping component and a sliding component, and the cutting mechanism includes a cutting knife. The clamping component includes clamping claws placed above the workbench, and a fixing component is arranged below the clamping claws. The sliding component includes slide rails arranged on both sides of the workbench and sliding claws placed above the workbench. The utility model adopts the above device for cutting a fixed length of clothing production fabric, which has a simple structure, is easy to operate, realizes the fixed-length cutting of the fabric, ensures the quality of the cut fabric, and saves manpower.

[0004] However, there are still some disadvantages when the above device is actually used. The more obvious one is that when the cutting knife performs edge cutting on the fabric on the processing table, it is difficult to stably place some fabrics at the bottom of the cutting knife during the conveying process, resulting in difficulty for some devices to accurately cut the edges of the fabric. At the same time, some fabrics are prone to wrinkles before being conveyed and cut, making some fabrics prone to deviate from the cutting line during the cutting process, resulting in large cutting errors for some fabrics, reducing the working efficiency and practicability of the device.

[0005] Therefore, it is very necessary to invent a cutting mechanism for non-woven fabric clothing fabrics to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a cutting mechanism for non-woven fabric clothing fabrics. By arranging a cutting component, the flattened non-woven fabric is located above the base. When both sides of the pressing block come into contact with the non-woven fabric, the non-woven fabric in the contact cutting area can be straightened. Since the non-woven fabric passes between the pressing block and the base, a pressing area is formed on the surface of the non-woven fabric passing through the pressing block. Furthermore, when the pressing block moves, the convex strip serves as a guide in the guiding groove, enabling the originally parallel fabric to be embedded in the guiding groove. Since the fabric has elasticity, the embedded fabric is in a taut state, so that fabrics with consistent width and neat cut edges can be cut. Compared with the method of cutting with scissors, the cutting efficiency can be significantly improved, so as to solve the problems proposed in the above background technology, that is, it is difficult to stably place some fabrics at the bottom of the cutting knife during the conveying process, resulting in difficulty for some devices to precisely trim the edges of the fabrics, and at the same time, some fabrics are prone to wrinkles before being conveyed and cut.

[0007] According to one aspect of the present disclosure, the following technical solution is provided: a cutting mechanism for non-woven fabric clothing fabrics, including a substrate, a first side plate is provided at the rear end of the substrate, second side plates are provided on both sides of the extended end of the substrate, and a cutting component is fixedly installed on the upper surface of the substrate;

A cutter fixing member is placed on the upper surface of the pressing block. A second avoidance groove is opened on the upper surface of the cutter fixing member. A disc cutter is fixedly installed on the inner side wall of the second avoidance groove through screws. The outer arc surface of the disc cutter penetrates into the guiding groove.

[0009] According to a cutting mechanism for non-woven fabric clothing fabrics of at least one embodiment of the present disclosure, the number of the first side plates is two.

The transmission components include synchronous wheels movably connected to the surfaces of the first side plates. A synchronous belt is movably sleeved on the outer arc surfaces of the synchronous wheels. A driven gear is fixedly installed on the back of one of the synchronous wheels.

[0010] According to a cutting mechanism for non-woven fabric clothing fabrics of at least one embodiment of the present disclosure, the outer arc surface serrations of the driven gear are meshed with a driving gear. The back of the driving gear is movably connected to one of the first side plates. A driving motor is fixedly installed on the back of the driving gear. The backs of both first side plates are fixedly installed with guiding members through bolts. One side of the guiding member is provided with an inclined end.

[0011] A non-woven fabric clothing fabric cutting mechanism according to at least one embodiment of the present disclosure. The number of the second side plates is two. A roller assembly is movably connected to one side surface of the two second side plates. The roller assembly includes a connecting shaft A movably connected to the bottom of the second side plate. A driving roller is movably clamped to one side of the connecting shaft A. A pulling plate is movably connected to the side of the second side plate away from the connecting shaft A.

[0012] A non-woven fabric clothing fabric cutting mechanism according to at least one embodiment of the present disclosure.

[0013] A non-woven fabric clothing fabric cutting mechanism according to at least one embodiment of the present disclosure. The outer arc surface of the pressure roller is attached to the surface of the driving roller. A tension spring is penetrated through the hole on one side of the swinging arm. One end of the tension spring is fixedly installed with a limit post. The end of the limit post is fixedly installed on the second side plate.

[0014] The technical effects and advantages of the present utility model:

[0015] 1. By placing the smoothed non-woven fabric above the base, when both sides of the pressing block come into contact with the non-woven fabric, the non-woven fabric in the contact cutting area can be straightened. Since the non-woven fabric passes between the pressing block and the base, a pressing area is formed on the surface of the non-woven fabric passing through the pressing block. Furthermore, when the pressing block moves, the convex strips serve as a guide in the guiding groove, enabling the originally parallel fabric to be embedded in the guiding groove. Since the fabric has elasticity, the embedded fabric is in a taut state, thus enabling the cutting of fabric with a consistent width and neat cut edges. Compared with the cutting method using scissors, the cutting efficiency can be significantly improved.

[0016] 2. When the angle between the connecting arm and the swinging arm is acute at the fabric conveying position, the pressure roller abuts against the driving roller to clamp the fabric, thereby facilitating the stable forward conveyance of the fabric while rotating with the driving roller. Under the self-gravity of the pressure roller, the wrinkles of the conveyed fabric can be smoothed, thus avoiding the situation where some fabrics are prone to deviate from the cutting line during the cutting process, resulting in fabric waste.

[0017] 3. By controlling the forward and reverse rotation of the driving motor, the circular cutting knife can move back and forth on the synchronous belt, thereby avoiding the situation where manual cutting affects the accuracy, realizing the fixed-length cutting of non-woven fabric, ensuring the quality of the cut fabric, and saving manpower.

[0031] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "over", "upper", and "side (e.g., as in "side wall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawing is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Additionally, the device can be positioned otherwise (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted.

[0032] Figure 4 is a disassembled structural schematic diagram of a cutting assembly 2 of a non-woven fabric garment fabric cutting mechanism according to an embodiment of the present disclosure.

[0033] As Figures 1-4 shown, a non-woven fabric garment fabric cutting mechanism of the present disclosure may include a substrate 1. A first side plate 11 is provided at the rear end of the substrate 1. Second side plates 12 are provided on both sides of the extended end of the substrate 1. A cutting assembly 2 is fixedly installed on the upper surface of the substrate 1. The cutting assembly 2 includes a base 21 fixedly installed on the upper surface of the substrate 1. A guide groove 22 is formed in the middle of the upper surface of the base 21. A strip-shaped groove is provided in the guide groove 22 of the base 21. A pressing block 23 is slidably clamped on the inner side wall of the guide groove 22. A convex strip 24 is provided in the middle of the lower surface of the pressing block 23. A first avoidance groove 25 is formed on the upper surface of the pressing block 23. A cutter fixing member 26 is placed on the upper surface of the pressing block 23. A second avoidance groove 27 is formed on the upper surface of the cutter fixing member 26. A disc cutter 28 is fixedly installed on the inner side wall of the second avoidance groove 27 by screws. The outer arc surface of the disc cutter 28 penetrates into the guide groove 22.

[0034] Thus, it is convenient for the non-woven fabric to be disposed above the guide groove 22, so that the smoothed non-woven fabric is located above the base 21. When both sides of the pressing block 23 come into contact with the non-woven fabric, the non-woven fabric in the contact cutting area can be straightened. Since the non-woven fabric passes between the pressing block and the base 21, an oppression area is formed on the surface of the non-woven fabric passing through the pressing block 23. Furthermore, when the pressing block moves, the convex strip 24 serves as a guide in the guide groove 22, enabling the originally parallel fabric to be embedded in the guide groove 22. Since the fabric has elasticity, the embedded fabric is in a taut state.

[0035] Subsequently, the disc cutter 28 is arranged such that at least part of its cutting edge can extend to the bottom surface of the guiding groove 22. The cutting edge of the disc cutter 28 is arranged towards the feeding direction of the fabric, and an angle of 10 - 80° can be formed between the cutting edge of the disc cutter 28 and the bottom surface of the guiding groove 22 to form a cutting opening for cutting the fabric. The position of the cutting opening can be set according to the cutting width of the fabric.

[0036] A first avoidance groove 25 is provided on the pressing block 23, which penetrates from the top to the bottom of the pressing block 23. The disc cutter 28 is arranged to extend from the top of the pressing block 23 through the first avoidance groove 25 to the bottom surface of the guiding groove 22. A second avoidance groove 27 is provided on the bottom surface of the guiding groove 22, and the second avoidance groove 27 is used to provide an avoidance space for the disc cutter 28, so that the disc cutter 28 can penetrate the bottom surface of the guiding groove 22 through the second avoidance groove 27, thereby achieving a better cutting effect.

[0037] Figure 2 It is a front view plane structure schematic diagram of the transmission component 3 of a non-woven fabric clothing fabric cutting mechanism according to an embodiment of the present disclosure.

[0038] As Figure 2 shown, in the present disclosure, the number of the first side plates 11 is two. The fronts of the two first side plates 11 are both movably connected with a transmission component 3 through a rotating shaft. The transmission component 3 includes a synchronous pulley 31 movably connected to the surface of the first side plate 11. A synchronous belt 32 is movably sleeved on the outer arc surface of the synchronous pulley 31. A driven gear 33 is fixedly installed on the back of one of the synchronous pulleys 31. The outer arc surface serrated part of the driven gear 33 is meshed and connected with a driving gear 34. The back of the driving gear 34 is movably connected to one of the first side plates 11 on one side. A driving motor 35 is fixedly installed on the back of the driving gear 34. The backs of the two first side plates 11 are fixedly installed with a guiding member 4 through bolts. An inclined end 41 is provided on one side of the guiding member 4.

[0039] Thus, it is convenient for the driving gear 34 to rotate driven by the driving motor 35. During the rotation process, the engaged driven gear 33 rotates relatively, thereby driving the rotation of the synchronous pulley 31, and further driving the operation of the synchronous belt 32. And the cutter fixing member 26 is connected to the bottom end of the synchronous belt 32. Therefore, by controlling the forward and reverse rotation of the driving motor 35, the back-and-forth movement of the disc cutter 28 is realized, thereby avoiding the situation that manual cutting affects the accuracy, achieving the fixed-length cutting of the non-woven fabric, ensuring the quality of the cut fabric, and saving manpower.

[0040] Figure 6 It is a partial enlarged structure schematic diagram at position A of the roller assembly 5 of a non-woven fabric clothing fabric cutting mechanism according to an embodiment of the present disclosure.

[0041] As Figure 5and Figure 6 As shown, in a preferred embodiment, the number of the second side plates 12 is two. A roller assembly 5 is movably connected to one side surface of the two second side plates 12. The roller assembly 5 includes a connecting shaft A51 movably connected to the bottom of the second side plate 12. A driving roller 52 is movably clamped to one side of the connecting shaft A51. A pulling plate 53 is movably connected to the side of the second side plate 12 away from the connecting shaft A51. The bottom of one side surface of the pulling plate 53 is movably connected to a connecting arm 54 through a rotating shaft. One side surface of the connecting arm 54 is movably connected to a swinging arm 55 through a rotating shaft. A hole is formed in the middle of the front surface of the swinging arm 55. A connecting shaft B56 is fixedly installed at the connection between the swinging arm 55 and the connecting arm 54. A pressure roller 57 is movably connected to one side of the connecting shaft B56. The outer arc surface of the pressure roller 57 is attached to the surface of the driving roller 52. A tension spring 58 passes through a hole on one side of the swinging arm 55. One end of the tension spring 58 is fixedly installed with a limit post 59, and the end of the limit post 59 is fixedly installed on the second side plate 12.

[0042] Thus, by arranging the connecting arm 54 at the position on the connecting shaft A51 and simultaneously arranging the pressure roller 57 on the connecting shaft B56 at the position, in this way, the pressure roller 57 can move between the fabric conveying position and the fabric picking and placing position along with the swing of the swinging arm 55. It should be noted that when the included angle between the connecting arm 54 and the swinging arm 55 is acute and in the fabric conveying position, the pressure roller 57 abuts against the driving roller 52 to clamp the fabric, so as to facilitate the stable forward conveying of the fabric while the driving roller 52 rotates. When the included angle between the connecting arm 54 and the swinging arm 55 is obtuse, there is a certain distance avoidance gap between the pressure roller 57 and the driving roller 52, so as to facilitate the operator to place the fabric between the pressure roller 57 and the driving roller 52 or to adjust the position of the fabric between the two, thereby improving the use convenience of the fabric picking and placing device.

[0043] Moreover, when the pressure roller 57 abuts against and clamps the driving roller 52, under the self-gravity of the pressure roller 57, the wrinkles of the conveyed fabric can be smoothed, so as to avoid the situation that some fabrics are prone to deviate from the cutting line during the cutting process, resulting in fabric waste. Since the first end of the tension spring 58 is connected to the swinging arm 55, the tension spring 58 connected to the swinging arm 55 provides a restoring force for the pressure roller 57 to move towards the fabric conveying position.
