Description

Technical Field

[0001] The utility model belongs to the technical field of cutting devices and relates to a cutting device, in particular to a fabric cutting device and a fabric cutting system. Background Art

[0002] Currently, PVC and polyester fabrics are typically cut with a utility knife after being laminated. Conventional products do not have the problem of lint adhering to the product surface after cutting. The main reason is that the polyester filaments used in conventional products are made from a single strand in both the warp and weft directions, running from front to back or left to right. The filaments are a complete single strand, so even when cutting, there is virtually no polyester filament dragged out. Furthermore, nearly all products have PVC on both the top and bottom layers, with the polyester fabric in the middle, for a total of three layers. This further reduces the risk of polyester filament dragged out.

[0003] Due to the development of new products, the fabric is still made of polyester yarn, but the key point is that the polyester yarn used in the weaving of the fabric is cut short, and these staple fibers are used for textile production. That is, although the fabric looks like a whole on the surface, it is actually composed of many staple fibers. Moreover, this type of product is different from conventional products. It has only two layers, the surface layer is PVC, and the bottom layer is a fabric made of polyester staple fibers. Therefore, it is easy to bring out the staple fibers during cutting after the PVC and fabric are compounded, causing a lot of staple fiber fluff to accumulate on the cutting knife, and also causing the staple fiber fluff to be adsorbed on the surface of the product. The most important use of this type of product is printing, and this type of fluff is adsorbed on the surface, so it will be printed on the fluff during printing. However, because the fluff and the finished product are simply adsorbed and easily separated, once the fluff is cleaned or falls off, the location where the fluff is located will obviously lack the printing effect, which will be easily discovered, seriously affecting the quality of the final product.

[0004] In view of this, there is an urgent need to design a new cutting method to overcome at least some of the above-mentioned defects of the existing cutting method. Utility Model Content

The same or similar existing technical means and some technical features of the embodiments are interchangeable and fall within the scope of the description and protection of the present invention.

[0029] The term “connection” in the specification includes both direct connection and indirect connection.

[0030] The utility model discloses a fabric cutting device. Figure 1 This is a schematic diagram of the structure of a fabric cutting device in one embodiment of the present invention; Figure 1 The fabric cutting device includes: a cutting mechanism 1, a suction pipe 2 and a suction mechanism, the suction pipe 2 is connected to the suction mechanism, and the suction pipe 2 is arranged on one side of the cutting mechanism 1.

[0031] The cutting mechanism 1 includes a knife holder 13 , a first cutting knife 11 , and a second cutting knife 12 . The first cutting knife 11 and the second cutting knife 12 are arranged based on the knife holder 13 .

[0032] The first end of the suction pipe 2 is provided with a notch 21. A sleeve 22 is provided at the first end of the suction pipe 2. The sleeve 22 is nested within the suction pipe 2 and can move along the area of the suction pipe 2 near the first end. The sleeve 22 is equipped with a fixing mechanism 23 that secures the sleeve 22 to a designated area of the suction pipe 2. The fixing mechanism 23 can be a screw. The notch 21 is located in the middle of the first end of the suction pipe 2. In a first state, the sleeve 22 covers the notch 21. In a second state, the sleeve 22 is located below the notch 21, exposing the notch 21.

[0033] In one embodiment, when the cutting blade is switched, the sleeve 22 is located below the notch 21 , thereby exposing the notch 21 ; a portion of the cutting blade in the working position is disposed in the notch 21 .

[0034] The suction pipe 2 may include a first tube body 24, a switching elbow 26 and a second tube body 25; one end of the switching elbow 26 is connected to the second end of the first tube body 24, the second end of the switching elbow 26 is connected to the first end of the second tube body 25, and the second end of the second tube body 25 is connected to the suction mechanism.

[0035] The outer diameter of the first tube body 24 corresponds to the inner diameter of the first end of the adapter elbow 26, and the inner diameter of the sleeve 2 is larger than the outer diameter of the first tube body 24; a portion of the first tube body 24 is exposed from the adapter elbow 26; the first tube body 24 is arranged longitudinally, and the adapter elbow 26 serves as a limiting mechanism for the sleeve 2, limiting the sleeve 2 to move within the exposed area of the first tube body 24.

[0036] The two sides of the tool holder 13 are respectively provided with a first tool fixing position and a second tool fixing position, which are used to fix the first cutting knife 11 and the second cutting knife 12 respectively; among the first cutting knife 11 and the second cutting knife 12, one cutting knife is used as a working cutting knife and the other is used as a spare cutting knife. When the spare cutting knife needs to be replaced, the operation of the working cutting knife is not affected.

[0037] The fabric cutting device may further include a position drive mechanism, which is connected to the tool holder and can drive the position of the tool holder. The fabric cutting device may further include a main control circuit and a position sensing module. The position sensing module is used to sense the distance of the distance setting object. The output end of the position sensing module is connected to the input end of the main control circuit to send the sensed distance data to the main control circuit; the output end of the main control circuit is connected to the input end of the position drive mechanism and can send a control signal to the position drive mechanism to control its operation. Through the above-mentioned structural setting, the fabric width can be input into the main control circuit through the input module (which can be input through the touch screen display). The main control circuit can then use the position drive mechanism to drive the position of the tool holder according to the position information sensed by the position sensing module, thereby achieving the purpose of automatically adjusting the tool holder and improving work efficiency and accuracy.

[0038] When the fabric cutting device of the present invention is used, the fabric includes a PVC layer 3 and a fabric layer 4 , and the suction pipe 2 is arranged on one side of the fabric layer 4 to absorb the short fiber fluff generated by the fabric layer 4 .

[0039] The utility model also discloses a fabric cutting system, which includes: a fabric conveying mechanism and at least one of the above-mentioned fabric cutting devices; the fabric conveying mechanism is connected to the fabric and can drive the fabric to move; each fabric cutting device is located at a set position on the fabric, cuts the fabric being conveyed and absorbs the short fiber fluff generated during the cutting process.

[0040] In one use scenario of the present invention, the present invention mainly connects a suction pipe below the cutting blade, and uses the suction device to suck away the short fiber fluff generated by cutting, thereby achieving the purpose of reducing the fluff on the surface of the product. The suction pipe is placed just below the intersection of the cutting blade and the product, and the suction device is turned on. The short fiber fluff generated during the cutting process will be sucked away, and the closer the suction port is to the intersection point, the better the effect of sucking away the short fiber fluff. However, the cutting blade needs to be replaced frequently. The cutting blade is installed on the tool holder, with one cutting blade on the upper and lower parts of the tool holder. One cutting blade is used and one cutting blade is spare. When the cutting blade needs to be replaced, the upper cutting blade is turned downward to replace it with a new cutting blade to work. However, the suction port is relatively close to the cutting point. When the cutting blade is replaced, the cutting blade head will hit the suction port. Therefore, a notch is cut at the suction port to ensure that the cutting blade passes through the notch during rotation, so that it will not hit the suction pipe. At the same time, considering that the existence of the gap will affect the suction effect to a certain extent, a sleeve is installed below the gap, and a small hole is opened on the sleeve to install screws. When normal operation does not require changing the cutting blade, the sleeve is completely covered with the gap and fixed to the suction pipe with screws. When the cutting blade needs to be replaced, the sleeve is moved down to expose the gap. After replacing the cutting blade, the sleeve is moved up again, covering the gap and fixing it with screws. This ensures the utilization rate of the suction device and achieves a better effect of sucking away lint.

[0041] In summary, the fabric cutting device and fabric cutting system proposed in this utility model, by using a suction device to remove the short fiber lint produced during cutting, can reduce or even prevent the short fiber lint from adhering to the product surface due to the severing of polyester staple fiber fabric during cutting, thereby improving the integrity of the product printing and ensuring the print quality of the finished product. This utility model can be used for products made of staple fiber fabrics where the short fiber lint is carried out during cutting and adsorbed on the product surface.
