Description

Technical Field

[0001] This utility model belongs to the field of fabric cutting technology, specifically a cutting device for curtain fabric production. Background Technology

[0002] Curtains are made of materials such as cloth, linen, gauze, aluminum sheets, wood sheets, or metal, and have the functions of shading, heat insulation, and regulating indoor light. Curtains used in different occasions have different sizes, so they need to be cut according to specific requirements. Existing cutting equipment involves installing sharp cutting blades on an automatic cutting head, laying the fabric flat, and then turning on the equipment to drive the cutting blades to cut the fabric. Smaller pieces of fabric can be straightened manually, but larger pieces are difficult to straighten manually, which affects the cutting accuracy. Moreover, if the blade sharpness decreases, it can cause the fabric to be pulled or even cut incorrectly, resulting in damage to the fabric. Therefore, it is necessary to develop a new type of cutting equipment for curtain fabric production to overcome the shortcomings of existing technology. Summary of the Invention

[0003] To address the problems mentioned in the background art, this utility model provides a cutting device for curtain fabric production, which has the advantage of good cutting effect.

[0005] The cutting assembly includes a first linkage frame that is slidably engaged inside the cutting seam. A cutting blade is fixedly engaged on both the left and right sides of the outer surface of the first linkage frame. Two adapter frames are fixedly connected to the outer surface of the first linkage frame. One adapter frame has a pressure roller installed on both the front and rear sides, and the other adapter frame has a drag roller installed on both the front and rear sides. A linkage assembly is fixedly connected to the bottom of the adapter frame. A linkage rack is engaged at the lower end of the linkage assembly. An adjustment assembly is provided inside the adapter frame, connecting the front and rear pressure rollers and the drag roller. An adjustment wheel is connected inside the adjustment assembly. The upper end of the linkage assembly is driven by the adjustment assembly and the pressure rollers and the drag roller.

[0007] Preferably, the lower end of the cutting blade extends into the interior of the cutting seam, and the bottoms of the adapter, pressure roller, and drag roller are all located above the curtain fabric at the top of the cutting table.

[0008] Preferably, the linkage rack is embedded in the front and rear sides of the first linkage frame, the outer surface of the linkage rack does not contact the first linkage frame, the two ends of the linkage rack are fixedly connected to the left and right ends of the inner cavity of the cutting seam, and ball bearings are embedded in the front and rear sides of the first linkage frame, the outer surface of the ball bearings extends to the outside of the first linkage frame and rolls in contact with the front and rear sides of the inner wall of the cutting seam.

[0009] Preferably, the drag roller and the pressure roller have the same structure, the outer surface roughness of the pressure roller is greater than that of the drag roller, and the outer circumferential diameter of the drag roller is smaller than that of the pressure roller;

[0010] Both the drag roller and the pressure roller are composed of a pressure roller body and an anti-slip sleeve. The side of the pressure roller body is provided with several evenly distributed grooves, and the anti-slip sleeve is fixedly fitted into the grooves.

[0011] Preferably, the adjusting assembly includes two limiting tubes fixedly sleeved between the front and rear pressure roller bodies. The limiting tubes are rotatably sleeved inside the adapter frame via bearings. The distal ends of the two limiting tubes extend into the interior of the front and rear pressure roller bodies.

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides a cutting device for producing curtain fabric, including a cutting table 1, a cutting slit 2 in the middle of the cutting table 1, a curtain fabric on top of the cutting slit 2, a cutting component 3 slidably engaged inside the cutting slit 2, and the upper end of the cutting component 3 passing through the cutting slit 2 and extending above the curtain fabric.

[0024] The cutting assembly 3 includes a first linkage frame 31 that slides and engages inside the cutting seam 2. A cutting blade 32 is fixedly engaged on both the left and right sides of the outer surface of the first linkage frame 31. Two adapter frames 33 are fixedly connected to the outer surface of the first linkage frame 31. One adapter frame 33 has a pressure roller 34 installed on both its front and rear sides, and the other adapter frame 33 has a drag roller 35 installed on both its front and rear sides. A linkage assembly 36 is fixedly connected to the bottom of the adapter frame 33, and a linkage rack 37 is engaged at the lower end of the linkage assembly 36. A connecting mechanism is provided inside the adapter frame 33. An adjusting assembly 38 is located between the front and rear pressure rollers 34 and the drag roller 35. An adjusting wheel 39 is connected inside the adjusting assembly 38. The upper end of the linkage assembly 36 is connected to the pressure rollers 34 and the drag roller 35 through the adjusting assembly 38. Due to the setting of the pressure rollers 34 and the drag roller 35, with the cooperation of the linkage assembly 36 and the linkage rack 37, the part of the cutting blade 32 that contacts the curtain fabric is always between the two pressure rollers 34 and the drag roller 35 during continuous cutting. This ensures that the curtain fabric is always kept straight when the cutting blade 32 cuts, thereby effectively improving the cutting effect.

[0025] like Figure 2 As shown, a lead screw is mounted on the bottom of the cutting table 1 via a bearing. One end of the lead screw is connected to a drive motor. A transmission sleeve 4 is threaded onto the outside of the lead screw. The top of the transmission sleeve 4 is fixedly connected to the bottom of the first linkage frame 31.

[0026] like Figure 1 and Figure 2 As shown, the lower end of the cutting blade 32 extends into the interior of the cutting seam 2, and the bottoms of the adapter frame 33, pressure roller 34 and drag roller 35 are all located above the top curtain fabric of the cutting table 1.

[0027] like Figure 2 As shown, the linkage rack 37 is embedded in the front and rear sides of the first linkage frame 31. The outer surface of the linkage rack 37 does not contact the first linkage frame 31. The two ends of the linkage rack 37 are fixedly connected to the left and right ends of the inner cavity of the cutting seam 2. Ball bearings are embedded in both the front and rear sides of the first linkage frame 31. The outer surface of the ball bearings extends to the outside of the first linkage frame 31 and rolls in contact with the front and rear sides of the inner wall of the cutting seam 2. Due to the setting of the ball bearings, the frictional resistance between the first linkage frame 31 and the inner wall of the cutting seam 2 can be effectively reduced. It also ensures that the movement of the first linkage frame 31 can be restricted inside the cutting seam 2 by the ball bearings, so as to prevent the first linkage frame 31 from rotating. This ensures that the lead screw can move the first linkage frame 31 laterally and reciprocally through the transmission sleeve 4.

[0028] like Figure 3 and Figure 4As shown, the drag roller 35 and the pressure roller 34 have the same structure. The outer surface roughness of the pressure roller 34 is greater than that of the drag roller 35, and the outer circumferential diameter of the drag roller 35 is smaller than that of the pressure roller 34. Since the diameter of the pressure roller 34 is greater than that of the drag roller 35, the relative sliding speed between the bottom of the drag roller 35 and the top of the curtain fabric is greater than that between the bottom of the pressure roller 34 and the top of the curtain fabric. This ensures that while the pressure roller 34 presses the curtain fabric, the drag roller 35 can drag the curtain fabric, thereby achieving the effect of straightening the curtain fabric.

[0029] Both the drag roller 35 and the pressure roller 34 are composed of a pressure roller body 341 and an anti-slip sleeve 342. The side of the pressure roller body 341 is provided with several evenly distributed slots, and the anti-slip sleeve 342 is fixedly fitted into the slots. Due to the setting of the anti-slip sleeve 342, it is not only convenient for the operator to adjust the diameter of the pressure roller 34 and the drag roller 35 with the cooperation of the adjustment component 38 and the adjustment wheel 39, but the anti-slip sleeve 342 also helps to improve the roughness of the outer surface of the pressure roller 34 and the drag roller 35.

[0030] like Figure 4 As shown, the adjusting assembly 38 includes two limiting tubes 381 fixedly sleeved between the front and rear pressure roller bodies 341. The limiting tubes 381 are rotatably sleeved inside the adapter frame 33 via bearings. The distal ends of the two limiting tubes 381 extend into the interior of the front and rear pressure roller bodies 341. The adjusting wheel 39 is disposed between the opposing surfaces of the two limiting tubes 381. Due to the setting of the limiting tubes 381, the pressure rollers 34 and the drag rollers 35 can be restricted with the cooperation of the adapter frame 33, so that the two can rotate smoothly and continuously with the linkage assembly 36. Moreover, the polygonal structure inside the limiting slider 382 and the outer surface of the limiting slider 382 can restrict the rotation of the limiting slider 382 and the adjusting tube 383. Thus, when the adjusting wheel 39 drives the adjusting rod 384 to rotate, the two limiting sliders 382 can be driven to move closer or further away from each other through the adjusting tube 383.

[0031] like Figure 4 As shown, a limiting slider 382 is slidably sleeved inside the limiting tube 381. An adjusting tube 383 is fixedly connected to the side of the outer surface of the limiting slider 382 near the adjusting wheel 39. An adjusting rod 384 is threaded inside the adjusting tube 383. The near ends of the two adjusting rods 384 pass through the adjusting tube 383 and extend to the outside of the limiting tube 381 and are fixedly connected to both sides of the adjusting wheel 39.

[0032] like Figures 2 to 4As shown, the linkage assembly 36 includes two front and rear second linkage frames 361 fixedly connected to the bottom of the adapter frame 33. The bottom of the two second linkage frames 361 facing each other are rotatably connected by bearings to a linkage gear 363 meshing with the bottom of the linkage rack 37. A transmission belt 362 is sleeved between the linkage gear 363 and the limiting tube 381. A limiting ring 364 is fixedly sleeved on the outer surface of the limiting tube 381. The transmission belt 362 is restricted between the limiting ring 364 and the inner wall of the adapter frame 33. The outer diameter of the linkage gear 363 is the same as the outer diameter of the pressure roller 34.

[0033] Working principle and usage process of this utility model:

[0034] Turning on the drive motor will cause the transmission sleeve 4 to move left and right via the lead screw, which in turn causes the first linkage frame 31 to move left and right. As the first linkage frame 31 moves, the cutting blade 32 can cut the curtain fabric laid flat on the top of the cutting table 1.

[0035] Rotating the adjusting wheel 39 will drive the two adjusting rods 384 to rotate synchronously. Then, under the restriction of the adjusting tube 383 by the adapter 33, the limiting tube 381 and the limiting slider 382, ​​the two adjusting rods 384 can push the two limiting sliders 382 away from each other with the cooperation of the adjusting tube 383. This will force the gas at both ends of the limiting tube 381 into the pressure roller 34 or the drag roller 35, which will cause the anti-slip sleeve 342 to expand, thereby pressing the pressure roller 34 and the drag roller 35 tightly against the top of the curtain fabric of different thicknesses.

[0036] When the first linkage frame 31 moves continuously, the linkage gear 363 rotates continuously in cooperation with the linkage rack 37. This, in turn, drives the pressure roller body 341 to rotate continuously via the transmission belt 362 and the adjusting component 38. Since the diameter of the pressure roller 34 is the same as the diameter of the linkage gear 363, when the linkage gear 363 rotates continuously with the movement of the first linkage frame 31 in cooperation with the linkage rack 37, it can ensure that the bottom of the pressure roller 34 can roll continuously along the top of the cutting table 1, pressing the curtain fabric while minimizing relative sliding with the top of the cutting table 1. In other words, it will not drag the curtain fabric. Since the outer diameter of the dragging roller 35 is smaller than that of the pressure roller 34, i.e. the outer diameter of the linkage gear 363, when the linkage gear 363 rotates continuously with the movement of the first linkage frame 31 in cooperation with the linkage rack 37, the bottom of the dragging roller 35 can rotate continuously along the top of the cutting table 1 and slide relative to the top surface of the cutting table 1, thereby dragging the curtain fabric during continuous movement. Due to the pressing action of the pressure roller 34 with a larger roughness, the curtain fabric is straightened and will not be dragged.
