Description

Technical Field

[0001] This utility model relates to the field of fabric processing, and specifically to a curtain fabric cutting device. Background Technology

[0002] In existing technologies, fabrics are cut using scissors or cutting blades. However, since curtain fabrics are woven from warp and weft threads, cutting the warp or weft threads during the cutting process can cause the warp or weft threads at the edges to come loose or come undone. In severe cases, this can easily lead to fabric defects and affect the quality of the curtains.

[0003] Patent number CN202121290205.X relates to the field of curtain production equipment, specifically a curtain fabric cutting device. The device includes a cutting platform and columns and frames on both sides of the platform. A guide crossbar is positioned between the frames on both sides of the platform. A sliding frame is mounted on the guide crossbar, and two vertically downward connecting rods are mounted on the sliding frame. A bearing seat is located at the lower end of each connecting rod, and a rotating shaft passes through the bearing seat. A circular cutting disc is mounted on the rotating shaft. The circular cutting disc has a hollow interior and contains an electric heating element. This invention provides a curtain fabric cutting device that can neatly cut curtain fabric and ensures that the warp and weft threads are not easily loosened after cutting, achieving a smooth edge for the curtain fabric.

[0004] Although the device uses a heated circular cutting blade to cut the fabric and then heat-seal the edges, the rotating circular cutting blade causes the heat-sealable threads to splatter outwards under centrifugal force, affecting the environment.

[0005] Therefore, in order to overcome the shortcomings of existing technologies, it is necessary to design a curtain fabric cutting device with a simple structure. Utility Model Content

[0006] This invention provides a curtain fabric cutting device to solve the problems of the prior art.

[0007] The objective of this utility model can be achieved through the following technical solution: A curtain fabric cutting device includes a base, a cutting component, a pressing component, a hot-melt component, and a dust-collecting component. The base has a cutting hole in the middle. The cutting component includes a frame, a cutter, a motor, and a cylinder. The cutter is rotatably mounted on the frame and positioned directly opposite the cutting hole. The motor drives and connects to the cutter. The cylinder is positioned at the upper end of the frame. The pressing component includes a bracket, a pressure plate, and a cylinder. The pressure plate is positioned at the lower end of the bracket, and the cylinder is positioned at the upper end of the bracket. The cutter passes through the bracket. The hot-melt component includes a cylinder and a hot-melt head. The cylinder is positioned on the bracket near the cutter. The hot-melt head is positioned at the lower end of the cylinder and inside the pressure plate. The dust-collecting component is positioned at the lower end of the cutting hole.

[0008] In a further improvement, the chip collection assembly includes a suction nozzle, a fan, and a chip collection bag. The suction nozzle is located at the lower end of the cutting hole, the fan is connected to the suction nozzle through a pipe, and the chip collection bag is connected to the fan through a pipe.

[0009] In a further improvement, the diameter of the lower end of the cutting hole is increased downwards.

[0010] In a further improvement, the width of the cutting blade is set to be equal to the width of the cutting hole.

[0011] In a further improvement, the clamping assembly also includes a second pressure plate, which is detachably mounted on both sides of the cutting hole of the base. The distance between the inner side of the second pressure plate and the center of the cutting hole is greater than the distance between the inner side of the pressure plate and the center of the cutting hole. The hot melt head is located above the second pressure plate.

[0012] Compared with the prior art, the beneficial effects of this utility model curtain fabric cutting device are as follows:

[0013] After the curtain fabric is transferred to the base, cylinder two drives the bracket to move downwards, causing the pressure plate to press the fabric firmly. A motor drives the cutter to rotate, coordinating with the downward movement of the cylinder to cut the fabric. Then, a dust collection component collects and absorbs the fabric dust after cutting, improving the quality of subsequent edge sealing. The pressure plate ensures that the cut edge remains inside the pressure plate, allowing some fabric to remain inside for heat sealing. The heat sealing head, driven by cylinder three, moves downwards to heat seal the excess fabric edge. The cutter and dust collection component work together to collect dust, and the downward-pressing heat sealing prevents the warp and weft threads from loosening, resulting in smooth edges for the curtain fabric and eliminating excess dust.

[0019] The following describes the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.

[0020] Example 1

[0021] A curtain fabric cutting device includes: a base 1, a cutting component 2, a pressing component 3, a heat-sealing component 4, and a dust-collecting component 5. The base 1 has a cutting hole 11 in the center. The cutting component 2 includes a frame 21, a cutter 22, a motor 23, and a cylinder 24. The cutter 22 is rotatably mounted on the frame 21 and directly opposite the cutting hole 11. The motor 23 drives and connects to the cutter 22. The cylinder 24 is located at the upper end of the frame 21. The pressing component 3 includes a support... The frame 31, pressure plate 32, and cylinder 33 are provided. The pressure plate 32 is located at the lower end of the frame 31, and the cylinder 33 is located at the upper end of the frame 31. The cutter 22 passes through the frame 31. The hot melt assembly 4 includes cylinder 41 and hot melt head 42. Cylinder 41 is located on the frame 31 near the side of the cutter 22. The hot melt head 42 is located at the lower end of cylinder 41 and inside the pressure plate 32. The chip suction assembly 5 is located at the lower end of the cutting hole 11.

[0022] like Figures 1-2As shown, the working principle of this utility model is as follows: After the curtain fabric is transferred to the base 1, the support 31 is moved down by the second cylinder 33, so that the pressure plate 32 presses the fabric. The motor 23 drives the cutter 22 to rotate and cooperates with the first cylinder 24 to move down, cutting the fabric. Then, the dust collection component 5 is used to absorb and collect the fabric dust after cutting, which can improve the quality of subsequent edge sealing. The pressure plate 32 presses the fabric to ensure that the cut position of the fabric is always inside the pressure plate 32 after cutting, so that part of the fabric is located inside the pressure plate 32 for heat sealing. The heat sealing head 42 moves down under the drive of the third cylinder 41 to heat seal the cut edge of the fabric that exceeds the cut edge. The dust collection is achieved by the cutter and the dust collection component. The edge sealing of the cut fabric by downward heat sealing is not easy for the warp and weft threads to loosen, achieving the flatness of the curtain fabric edge and no excess dust is generated.

[0023] As a further preferred embodiment, the chip collection assembly 5 includes a suction nozzle 51, a fan 52, and a chip collection bag 53. The suction nozzle 51 is disposed at the lower end of the cutting hole 11, the fan 52 is connected to the suction nozzle 51 through a pipe, and the chip collection bag 53 is connected to the fan 52 through a pipe.

[0024] As a further preferred embodiment, the lower diameter of the cutting hole 11 is increased downwards, thereby increasing the suction area of ​​the suction nozzle 51 through the shape of the lower cutting hole 11.

[0025] As a further preferred embodiment, the width of the cutting blade 22 is set to be equal to the width of the cutting hole 11 to ensure cutting accuracy, so that the excess length of the fabric after cutting is small, thereby reducing the length of the edge sealing.

[0026] As a further preferred embodiment, the pressing assembly 3 also includes a second pressing plate 34, which is detachably disposed on both sides of the cutting hole 11 of the base 1. The distance between the inner side of the second pressing plate 34 and the center of the cutting hole 11 is greater than the distance between the inner side of the pressing plate 32 and the center of the cutting hole 11. The hot-melt head 42 is located above the second pressing plate 34. After multiple hot-melt processes on the fabric edge, edge-sealing waste is easily generated on the second pressing plate 34, which facilitates the disassembly and cleaning of the second pressing plate 34 and ensures the quality of subsequent edge sealing.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
