Description

Technical Field

[0001] This utility model relates to the field of fabric cutting machine technology, specifically a fabric cutting machine with a fabric pressing structure. Background Technology

[0002] Fabric cutting machines are widely used in the textile, apparel, home furnishing, and bag industries. In the apparel industry, they can precisely cut various fabrics into garment pieces according to patterns, supporting batch multi-layer cutting and improving efficiency. In the home furnishing sector, they are used for cutting fabrics such as curtains and sofa covers to size. In addition, they are also suitable for special scenarios such as industrial fabrics and automotive interiors.

[0003] A novel fabric cutting machine, as disclosed in authorization announcement number CN205368857U, includes a machine body, guide wheels, a fabric pulling wheel, a motor, a cutting knife, a hydraulic inner arm, a cutting table, and hydraulic pipes. The machine body has a feed inlet and a support frame mounted on its upper side, with a feed groove on the feed inlet. A hydraulic pipe with a hydraulic gauge mounted on its upper side is also mounted on the machine body. Inside the machine body, a guide wheel is installed, and below the guide wheel is a fabric pulling wheel. Below the fabric pulling wheel is a conveying device connected to the motor via a belt. Inside the machine body, a hydraulic outer arm is mounted on its upper side, and below it is a hydraulic inner arm. A shock absorber is mounted below the hydraulic inner arm, and below the shock absorber is a cutting knife. Below the cutting knife is a cutting table, and on the right side of the cutting table is a discharge port. This invention includes a measuring device inside the upper side of the machine body, which can effectively detect the length of the cut fabric.

[0004] Although the above-mentioned solution can effectively detect the length of the fabric by installing a measuring device on the upper side inside the fabric cutting machine body, the structure of the fabric cutting machine is relatively complex and lacks a pressing measure for the fabric during cutting. This makes it easy for the cutting blade to cause the fabric to wrinkle or shift when cutting the fabric, affecting the cutting accuracy and neatness. To this end, we propose a fabric cutting machine with a pressing structure, which solves the problem of the lack of fabric pressing measures during fabric cutting, improves the stability of the fabric during cutting, and reduces the problems of uneven cut edges and poor accuracy caused by fabric wrinkles or shifts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This fabric cutting machine with a fabric pressing structure, through the fabric pressing mechanism set on both sides of the fabric cutting knife, when the fabric cutting knife moves towards the top surface of the cutting table, because the horizontal height of the strip pressing plate is lower than the height of the fabric cutting knife in the relaxed state, the strip pressing plate contacts the fabric before the fabric cutting knife. As the fixed frame continues to move downward, the strip pressing plate is blocked by the cutting table. At this time, the movable rod slides upward along the limiting slide groove, and the return spring is compressed. The elastic potential energy of the return spring is used to make the strip pressing plate press the fabric tightly, thereby providing a more stable cutting surface for the cutting knife to cut, avoiding the fabric wrinkles during the cutting process from affecting the cutting accuracy and the flatness of the cut edge, and improving the production quality.

[0014] 2. This fabric cutting machine with a fabric pressing structure allows workers to quickly and accurately locate the cutting position of the fabric by using a reference scale perpendicular to the pre-reserved slit on the top surface of the cutting table, thereby improving production efficiency.

[0015] 3.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model 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 this utility model.

[0023] Example: A fabric cutting machine with a fabric pressing structure, such as Figures 1-3 As shown, the device includes a cutting table 1, a vertical plate 2 fixedly mounted on one side of the cutting table 1, a support platform 3 fixedly mounted on the top of the vertical plate 2, a hydraulic lifting rod 4 fixedly mounted on the top surface of the support platform 3, the bottom end of the hydraulic lifting rod 4 extending through the support platform 3 toward the cutting table 1, a cutting mechanism 5 fixedly connected to the bottom end of the hydraulic lifting rod 4, a fabric pressing mechanism 6 provided at the bottom end of the cutting mechanism 5, the cutting mechanism 5 including a fixed frame 51, a servo motor 52 fixedly mounted on one side of the fixed frame 51, a fabric cutting knife 53 fixedly connected to the output end of the servo motor 52, the cutting mechanism 5 also including a protective cover 54, the protective cover 54 located outside the fabric cutting knife 53 and fixedly mounted inside the fixed frame 51, the rotation shaft of the fabric cutting knife 53 passing through the protective cover 54 and fixedly connected to the output end of the servo motor 52, a reserved slit 11 opened on the top surface of the cutting table 1, the reserved slit 11 located directly below the fabric cutting knife 53, a reference scale 12 fixedly mounted on the top surface of the cutting table 1, the reference scale 12 being perpendicular to the reserved slit 11.

[0024] In this embodiment, using the reference scale 12 set on the top surface of the cutting table 1, the worker first lays the fabric to be cut flat on the cutting table 1 and finds the cutting position. The hydraulic lifting rod 4 drives the fixing frame 51 to move down to the top surface of the cutting table 1, and the servo motor 52 drives the cutting knife 53 to rotate, thereby achieving the cutting effect of the fabric.

[0025] like Figures 1-4As shown, the fabric pressing mechanism 6 includes a strip-shaped pressing plate 61. A movable rod 62 is fixedly installed on the top surface of the strip-shaped pressing plate 61. The top end of the movable rod 62 is slidably connected to the fixed frame 51. A return spring 63 is sleeved on the outer side of the lower end of the movable rod 62. There are two sets of fabric pressing mechanisms 6, which are symmetrically arranged around the fabric cutter 53. A limiting groove 67 is opened inside the fixed frame 51. A limiting block 64 is fixedly installed on the top end of the movable rod 62. The limiting block 64 and the limiting groove 67 are in contact with each other and slidably connected. The bottom end of the return spring 63 is fixedly connected to the top surface of the strip-shaped pressing plate 61, and an annular sleeve 65 is fixedly connected to its top end. The annular sleeve 65 is sleeved on the movable rod. On the outside of 62, the outer diameter of the annular sleeve 65 is larger than the inner diameter of the limiting slide groove 67. A retaining ring 66 is fixedly installed on the inner wall of the limiting slide groove 67 near one end of the strip pressure plate 61. A movable rod 62 is slidably connected inside the retaining ring 66. The two ends of the strip pressure plate 61 are rounded. There are two movable rods 62, which are symmetrically arranged with respect to the center line of the long side of the strip pressure plate 61. The strip pressure plate 61 is made of metal material with a smooth bottom surface. An auxiliary lighting lamp 7 is fixedly installed on the side of the upright plate 2 near the cutting table 1. A PLC control panel 8 is fixedly installed on the side wall of the cutting table 1. The PLC control panel 8 is electrically connected to the hydraulic lifting rod 4 and the servo motor 52.

[0026] In this embodiment, the hydraulic lifting rod 4 drives the fixed frame 51 to move downward, and simultaneously drives the fabric pressing mechanism 6 to move downward. Since the horizontal height of the strip pressure plate 61 is lower than the height of the cutting knife 53 when the cutting knife 53 moves down to the fabric, the strip pressure plate 61 contacts the fabric before the cutting knife 53. As the hydraulic lifting rod 4 extends, the fixed frame 51 continues to move downward, while the strip pressure plate 61 is blocked by the cutting table 1. At this time, the movable rod 62 slides upward along the limiting slide groove 67, and the return spring 63 is compressed. The elastic potential energy of the return spring 63 makes the strip pressure plate 61 press the fabric, thereby providing a more stable cutting surface for the cutting operation of the cutting knife 53 and avoiding the fabric wrinkles affecting the cutting accuracy during the cutting process.

[0027] In this embodiment, a fabric cutting machine with a pressing structure is used. First, the fabric to be cut is laid flat on the cutting table 1 using the reference scale 12 set on the top surface of the cutting table 1, and the cutting position is found. Then, the hydraulic lifting rod 4 is extended through the PLC control panel 8, which causes the telescopic rod to move the cutting knife 53 and the strip pressing plate 61 downward. Since the horizontal height of the strip pressing plate 61 is lower than the height of the cutting knife 53 when the cutting knife 53 moves down to the fabric, the strip pressing plate 61 contacts the fabric before the cutting knife 53. As the hydraulic lifting rod 4 extends, the fixed frame 51 continues to move downward, while the strip pressing plate 61 is blocked by the cutting table 1. At this time, the movable rod 62 slides upward along the limiting slide groove 67, and the return spring 63 is compressed. The elastic potential energy of the return spring 63 makes the strip pressing plate 61 press the fabric tightly, thereby providing a more stable cutting surface for the cutting operation of the cutting knife 53 and avoiding the influence of fabric wrinkles on cutting accuracy during the cutting process. Finally, the servo motor 52 is started via the PLC control panel 8 to drive the fabric cutter 53 to rotate, thereby achieving the cutting effect on the fabric. After cutting is completed, the servo motor 52 is turned off first, and then the hydraulic lifting rod 4 is controlled to retract, so that the next round of cutting can begin.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
