Description

Technical Field

[0001] This utility model belongs to the technical field of fabric production equipment, and in particular relates to a fabric cutting frame. Background Technology

[0002] In existing fabric cutting equipment, the cutting blades are usually fixedly mounted on the frame, and their cutting height is not adjustable. When processing fabrics of different thicknesses or materials (such as thin yarn and thick canvas), frequent blade changes or equipment adjustments are required, resulting in low efficiency and safety hazards. Although some equipment offers limited height adjustment functions, it relies on manual disassembly or complex tool operation, resulting in low adjustment accuracy and poor stability. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a fabric cutting frame that enables rapid and precise adjustment of the blade height, supporting a single operator to independently complete the cutting of multiple specifications of fabric.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a fabric cutting frame, comprising a mounting frame mounted on a fabric cutting machine frame and fabric cutting components mounted on the mounting frame. The fabric cutting components include a base frame mounted on the mounting frame, a rotatable rotating blade holder mounted on the base frame, a blade fixed to the rotating blade holder, and a rotation drive element for driving the rotating blade holder to rotate. The rotation drive element is mounted on the base frame, and its output end is connected to the rotating blade holder. With the drive of the rotation drive element, the rotating blade holder can be driven to rotate relative to the base frame, and the height of the blade will change accordingly. The mounting frame is provided with a plurality of fabric cutting components.

[0005] Preferably, the rotary tool holder includes a rotating part and a mounting part fixedly connected to the lower side of the rotating part. A rotating groove is provided on the base frame, and the rotating part is fitted into the rotating groove and can rotate relative to the base frame along the guide of the rotating groove. The tool is fixedly mounted on the mounting part.

[0006] Preferably, the rotary drive element is a hydraulic cylinder, one end of which is hinged to the base frame and the other end of which is hinged to one side of the rotary tool holder.

[0007] Preferably, the mounting frame includes a mounting rod fixedly mounted on the fabric cutting machine frame and a track platform fixedly connected to the mounting rod. The track platform extends along the axial direction of the mounting rod. The base frame is sleeved on the mounting rod and has a track groove. The base frame slides with the track platform through the track groove.

[0008] Preferably, the track platform and the mounting rod are separate structures.

[0009] Preferably, the track platform is provided with a plurality of positioning holes evenly distributed along its length, and the base frame is provided with fixing blocks on both sides. Each fixing block is provided with a fixing hole, and a threaded component is provided in the fixing hole. The threaded component passes through the fixing hole and its end is threadedly engaged with the positioning hole. The fixing block generates a compressive force on the base frame from the fixing block to the base frame.

[0010] Preferably, a compensation block is provided between the fixing block and the base frame.

[0011] The technical effect of this utility model is as follows: Through innovative structural design, the height of the cutter can be quickly and accurately adjusted, supporting a single operator to independently complete the cutting of multiple specifications of fabric.

[0017] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0018] like Figures 1-4 As shown, a fabric cutting frame includes a mounting frame 1 and a fabric cutting assembly 2. The mounting frame 1 is a prior art device and can be an integrally fixed mounting frame to an existing fabric cutting device frame. The mounting frame 1 is fixedly installed with a mounting rod 3 at the processing station of the fabric cutting function. A strip groove is opened at the top of the mounting rod 3, and a track platform 4 is inserted in the strip groove. The track platform 4 is detachably fixed to the mounting rod 3 by bolts. The track platform 4 extends along the length direction of the mounting rod 3, and its top is higher than the opening of the strip groove.

[0019] Furthermore, multiple sets of fabric cutting components 2 are installed on the mounting rod 3. The fabric cutting component 2 includes a base frame 5, a rotating blade holder 6, a blade 7, and a rotating drive element 8. The base frame 5 is sleeved on the mounting rod 3 and has a track groove. A slider is installed in the track groove and slides with the track platform 4.

[0020] Furthermore, in some embodiments, the track platform 4 is provided with a plurality of positioning holes 9 evenly distributed along its length, and the base frame 5 is provided with fixing blocks 10 on both sides. The fixing blocks 10 are provided with fixing holes, and the fixing holes are provided with threaded parts 11. The threaded parts 11 are bolts, which pass through the fixing holes and their ends are threaded into the positioning holes 9. One side of the fixing block 10 presses against the base frame 5. In other embodiments, if there is still a gap between the fixing block 10 and the base frame 5 when the fixing block 10 is fixed by bolts, a suitable compensation block 12 is selected accordingly. The compensation block 12 is located between the fixing block 10 and the base frame 5 to ensure the limiting and fixing of the base frame 5.

[0021] Furthermore, the base frame 5 is provided with a rotating groove 13, and the rotating tool holder 6 includes a rotating part 14 and a mounting part 15. The rotating part 14 is a ring structure, which is rotatably sleeved in the rotating groove 13 and can rotate around the center of the mounting rod 3. The mounting part 15 is a plate structure, which is integrally fixed to the rotating part 14 and is located at an obliquely lower position of the rotating part 14. The rotating drive element 8 is a hydraulic cylinder. A mounting plate is fixedly connected to one side of the base frame 5. One end of the hydraulic cylinder is hinged to the mounting plate, and the other end is hinged to the rotating part 14. By extending and retracting the hydraulic cylinder, the rotating tool holder 6 can be driven to rotate relative to the rotating groove 13. A cutting tool 7 is fixedly installed on the end of the mounting part 15 away from the rotating part 14. The cutting tool 7 is of the prior art.
