Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a fabric anti-pleat cutting device. Background Technology

[0002] Woven fabric is a fabric made by interlacing two systems of yarns, arranged perpendicularly to each other (the transverse and longitudinal systems), on a loom according to a certain pattern. The fabric needs to be cut during the production process.

[0003] For example, Chinese patent document CN221918694U discloses a cutting device for processing knitted fabric, comprising: a conveying device having a starting end and an ending end for conveying the knitted fabric; a cutting device mounted on the top of the conveying device for cutting the knitted fabric; and a pressure plate assembly disposed on both sides of the cutting device for pressing the knitted fabric.

[0004] In the above technical solution, the knitted fabric is pressed by multiple pressure plate components, which facilitates cutting. However, the pressure plate components are only set at the edge of the fabric and can only press the fabric, not across the entire fabric. As a result, the unpressed areas of the fabric are still prone to curling up and wrinkling during cutting, which affects the cutting quality of the fabric. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fabric anti-wrinkle cutting device that can fully press the fabric to prevent it from curling up during cutting and ensure the cutting quality of the fabric.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fabric anti-wrinkle cutting device, comprising a machine base, a gantry frame that can move along the length of the machine base, a hydraulic cylinder that can move along the length of the gantry frame, a cutting head connected to the output end of the hydraulic cylinder, symmetrical pressure rollers on both sides of the cutting head, the pressure rollers extending along the width of the machine base, and the pressure rollers moving with the movement of the gantry frame.

[0007] The present invention is further configured such that: connecting angle steel is provided on both sides of the gantry frame, and the two ends of the pressure roller are respectively connected to the connecting angle steel on both sides.

[0008] The present invention is further configured such that: the gantry frame is provided with a through waist hole, the waist hole extends in a vertical direction, the connecting angle steel is provided with a through connecting hole, the connecting hole can be opposite to the waist hole, and the connecting hole and the waist hole are fixed by a locking member.

[0009] The present invention is further configured such that: the pressure roller is provided with connecting flanges at both ends, and the connecting angle steel on both sides is provided with a first connecting seat and a second connecting seat respectively, and the connecting flanges on both sides are respectively connected to the outer wall of the first connecting seat and the outer wall of the second connecting seat.

[0010] The present invention is further configured such that: a rotatable bidirectional lead screw and a guide rod are respectively provided on both sides of the gantry frame; a first connecting seat is respectively fitted at both ends of the bidirectional lead screw and forms a threaded engagement; the second connecting seat is fitted on the outer periphery of the guide rod and forms a sliding engagement; the bidirectional lead screw rotates to drive the first connecting seats on both sides to move towards each other or away from each other, thereby realizing the adjustment of the distance between the pressure rollers on both sides.

[0011] The present invention is further configured such that one end of the bidirectional lead screw extends outward as a driving end, and the driving end is provided with an axially recessed internal hexagonal groove.

[0012] The present invention is further configured such that: the outer periphery of the driving end is provided with an external thread, and a locking nut that can form a threaded engagement with the driving end is fitted on the outer periphery of the driving end.

[0013] The present invention is further configured such that the end of the pressure roller is rotatably connected to the connecting flange.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Because symmetrical pressure rollers are provided on both sides of the cutting head, these pressure rollers are used to press the fabric on the machine table. The pressure rollers extend along the width direction of the machine table, allowing them to traverse the fabric across its width. This solves the technical problem of insufficient pressing of the fabric in existing technologies. Furthermore, the pressure rollers are connected to the gantry, so they can move with the gantry, maintaining relative restraint between the pressure rollers and the cutting head and preventing blade collisions. Since the pressure rollers are located on both sides of the cutting head's blade, it ensures that the pressure rollers always contact the fabric first when the cutting head cuts along the length of the machine table. As the gantry moves, the pressure rollers can smooth the fabric surface with their own weight, preventing wrinkles in the fabric along the subsequent movement path of the cutting head. When the cutting head cuts along the width direction of the machine table, the pressure rollers on both sides press the fabric, preventing the fabric from lifting between the two pressure rollers, thus ensuring the cutting quality of the fabric.

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for 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 invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 4 As shown, this utility model discloses a fabric anti-wrinkle cutting device, including a machine base 1, a gantry frame 2 that can move along the length of the machine base 1, a hydraulic cylinder 3 that can move along the length of the gantry frame 2, and a cutting head 4 connected to the output end of the hydraulic cylinder 3. Through the moving structure of the gantry frame 2 and the hydraulic cylinder 3, the cutting head 4 can be driven to move along the length and width of the machine base 1 respectively, so as to cut the fabric laid on the machine base 1 in multiple directions. The movement of the gantry frame 2 and the hydraulic cylinder 3 is powered by gears and racks. This is an existing structure, so it will not be described in detail.

[0023] In this embodiment, symmetrical pressure rollers 5 are provided on both sides of the cutting head 4. These pressure rollers 5 are used to press the fabric on the machine table 1. The pressure rollers 5 extend along the width direction of the machine table 1, allowing them to traverse the fabric across its width. The pressure rollers 5 are connected to the gantry 2, enabling them to move with the gantry 2. This maintains a relative distance between the pressure rollers 5 and the cutting head 4, preventing blade collisions. Furthermore, since the pressure rollers 5 are positioned on both sides of the cutting head 4's blade... This ensures that when the cutting head 4 cuts along the length of the machine table 1, the pressure roller 5 always contacts the fabric first. As the gantry 2 moves, the pressure roller 5 can smooth the surface of the fabric by its own weight, preventing wrinkles from appearing on the fabric along the subsequent movement path of the cutting head 4. When the cutting head 4 cuts along the width of the machine table 1, the pressure rollers 5 on both sides can press the fabric, preventing the fabric between the two pressure rollers 5 from lifting up, thus ensuring the cutting quality of the fabric.

[0024] In this embodiment, the connection structure between the pressure roller 5 and the gantry frame 2 is as follows: connecting angle steel 6 is provided on both sides of the gantry frame 2, and the gantry frame 2 is provided with a through waist hole 21 extending vertically. The connecting angle steel 6 is provided with a through connecting hole, which can be opposite to the waist hole 21. The two ends of the pressure roller 5 are respectively connected to the connecting angle steel 6 on both sides. By providing the waist hole 21 extending vertically, the vertical position of the connecting angle steel 6 can be easily adjusted when the connecting angle steel 6 is installed, thereby facilitating the adjustment of the distance between the pressure roller 5 and the machine base 1. When the connecting angle steel 6 is moved to the target position, the connecting hole and the waist hole 21 are fixed by a locking component. The locking component can be a long bolt and a nut. When the long bolt is passed through the waist hole 21 from one side of the gantry frame 2, the connection between the connecting angle steel 6 and the gantry frame 2 can be completed by screwing in the nut for locking.

[0025] Furthermore, the connection structure between the pressure roller 5 and the connecting angle steel 6 is as follows: connecting flanges 7 are provided at both ends of the pressure roller 5; a first connecting seat 8 and a second connecting seat 9 are respectively provided on the connecting angle steel 6 on both sides; the connecting flanges 7 on both sides are fixed to the outer walls of the first connecting seat 8 and the second connecting seat 9 respectively by threaded connection; a rotatable bidirectional screw 10 and a guide rod 11 are respectively provided on both sides of the gantry frame 2; bearing seats and bases are respectively provided on the connecting angle steel 6 on both sides; the two ends of the bidirectional screw 10 are rotatably connected to the bearing seats through the bearings of the bearing seats; and the two ends of the guide rod 11 are... The two-way lead screw 10 is fixed to the base on both sides. The first connecting seat 8 is respectively fitted on both ends of the lead screw 10 and they form a threaded engagement. The second connecting seat 9 is fitted on the outer periphery of the guide rod 11 and forms a sliding engagement. By rotating the two-way lead screw 10, the first connecting seats 8 on both sides can be driven to move towards each other or away from each other under the guidance of the guide rod 11 and the second connecting seat 9. This realizes the adjustment of the distance between the two pressure rollers 5, so as to adapt to the different specifications of the cutting head 4, avoid the collision of the blades, and improve the efficiency of adjusting the distance between the two pressure rollers 5.

[0026] In this embodiment, one end of the bidirectional lead screw 10 extends outward as a drive end 101. The drive end 101 is provided with an axially recessed internal hexagonal groove 102. When it is necessary to drive the bidirectional lead screw 10 to rotate, an internal hexagonal wrench adapted to the internal hexagonal groove 102 can be used to rotate the bidirectional lead screw 10 through the drive end 101, thereby facilitating the rotation of the bidirectional lead screw 10.

[0027] In this embodiment, the threads on the outer periphery of the first connecting seat 8 and the bidirectional lead screw 10 can achieve self-locking. To further prevent the bidirectional lead screw 10 from rotating erroneously, an external thread is further provided on the outer periphery of the drive end 101. A locking nut 12 that can form a threaded engagement with the drive end 101 is fitted on the outer periphery of the drive end 101. When the distance between the two pressure rollers 5 is adjusted to the target distance, the locking nut 12 can be screwed into the outer periphery of the drive end 101 to lock the bidirectional lead screw 10 and prevent the bidirectional lead screw 10 from rotating erroneously. When it is necessary to drive the bidirectional lead screw 10 to rotate, the locking nut 12 can be loosened.

[0028] In this embodiment, the end of the pressure roller 5 is rotatably connected to the connecting flange 7 via a pin. Thus, as the pressure roller 5 moves with the gantry 2 and comes into contact with the fabric on the machine platform 1, the pressure roller 5 can rotate around its axis, so that the friction generated by contact with the fabric is rolling friction, thereby reducing the wear on the fabric when smoothing it.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
