Description

Technical Field

[0001] The invention relates to a knife clamping turntable for an automatic cutting machine, which is mainly used for clamping, rotating and cooling a cutting knife of the automatic cutting machine. Background Art

[0002] The knife clamping turntable (also called the cutting knife presser foot) used in the current automatic cutting machine has the function of clamping the cutting knife to rotate and slide up and down to cut the fabric. Because this traditional knife clamping turntable adopts an air-cooled structure for clamping the cutting knife, and the friction parts are all metal roller friction, coupled with the high-speed friction between the cutting knife and the fabric when cutting the fabric, the cutting knife heats up very much, so that the automatic cutting machine has difficulty in cutting those fusible chemical fiber fabrics, because the heating of the cutting knife causes the chemical fiber fabric to melt and stick together. Therefore, until now, the automatic cutting machine still has difficulty in cutting those chemical fiber fabrics in batches, and cutting a small number of layers is too costly and not economically cost-effective, so chemical fiber fabrics are still mainly cut manually.

[0003] In addition, it is also a problem for current automatic cutting machines to cut those airtight fabrics. At present, most of them are still at the technical level of a small number of layers. Because the airtight fabrics are pumped with negative pressure, the atmospheric pressure only acts on the surface layer of the fabric. The fabric below is not airtight and cannot be locked by the pressure after the negative pressure is pumped like those breathable fabrics. Once the cutter cuts the upper fabric, the atmospheric pressure will be greatly reduced, causing the lower layer of fabric to slide when the cutter is cutting the fabric, resulting in the fabric being cut non-standardly, and serious deviations will even cause it to be scrapped.

[0004] Furthermore, the current automatic cutting machine has a knife sharpening function which is a system independent of the knife clamping turntable. The knife sharpening system is complex, the knife sharpening wheel is large, and the production cost is high. Since the knife sharpening wheel is a consumable, the cost of use is also high, which directly affects the cost of using the cutting machine.

[0005] In addition, because the knife clamping turntable of the current automatic cutting machine is installed at the upper position of the knife clamping turntable, and the clamping wheel is also installed on the upper part of the knife clamping turntable, this causes the length of the cutter hanging from the working surface below to be too long, and the cutter is a slender tool. When cutting the fabric, the cutter is easily offset or even broken due to the long hanging length below the cutter and the great resistance when cutting the fabric. Summary of the invention

[0006] The object of the present invention is to provide a knife clamping turntable for an automatic cutting machine to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention is a kind of automatic cutting machine knife clamping turntable designed, comprising: a knife clamping disc body, a film laminating opening, a cutting knife support seat, a cutting knife groove, a knife clamping wheel, a controllable dripping head, a universal ball assembly, a sharpening wheel, a knife sharpening motor, a knife clamping disc mounting hole, and a controllable liquid flow device; the knife clamping disc body is provided with a film laminating opening which passes through the upper and lower surfaces of the knife clamping disc body; the knife clamping disc body is provided with a cutting knife groove which passes through the upper and lower surfaces of the knife clamping disc body, and a cutting knife support seat is installed at one end of the cutting knife groove, and the cutting knife support seat passes through the upper and lower surfaces of the knife clamping disc body and is fixedly installed; the controllable dripping head is fixedly installed on any one side or both sides of the cutting knife groove; the sharpening wheel and the sharpening motor are installed on one side or both sides of the cutting knife groove; the universal ball assembly is rotatably installed on the lower end of the knife clamping disc body, and the ball protrudes from the lower surface of the knife clamping disc.

[0008] The grinding wheel can be coaxially connected to the grinding motor to form an integrated structure, or the grinding wheel can be fixedly installed on the grinding wheel seat and then separately installed with the grinding motor and driven to rotate by belt connection. The grinding wheel moving device is fixedly installed on the grinding wheel seat or one end or one side of the grinding motor, and the output end of the grinding wheel moving device is elastically connected to the grinding wheel motor (or the grinding wheel seat 12) by a spring.

[0009] The laminating opening is located at one end of the cutting groove near the cutting knife support, and has a slot passing through the upper and lower surfaces of the cutting knife disc body. The shape of the laminating opening is not limited as long as it can satisfy the function of allowing flexible film materials to pass through the opening.

[0010] The universal ball assembly can use either a spring-loaded retractable ball assembly or a non-elastic universal ball assembly. The material of the universal ball assembly is not limited. The number of the universal ball assembly is at least two or more, and they are arranged in unequal intervals. The universal ball assembly can be arranged in an irregular manner with unequal intervals or can be installed in an equidistant regular arrangement. The universal ball assembly includes any component that can roll and rotate in a universal direction, such as a universal ball, a universal wheel, a universal ball, etc.

[0011] The controllable dripper can be in a square, circular or other shape, as long as it can satisfy the function of liquid passing through. There is at least one controllable dripper.

[0012] The controllable flow liquid device is composed of a hollow tube and a valve capable of controlling the flow rate of the liquid. The valve can be fixedly installed on the main body of the knife clamping disc or installed outside the knife clamping disc. The liquid flows through the valve through the tube to the controllable drip head, the cutter holder and the grinding wheel. Beneficial effects of the present invention:

[0013] In summary, according to the existing problems, the present invention provides a new technical solution to these problems, and its beneficial effects are as follows: The liquid cooling technology solution is adopted, so that the cutter can be directly cooled by liquid to achieve a better cooling effect. It is no longer a problem to cut those fusible chemical fiber fabrics.

[0014] The cutter holder that passes through the upper and lower surfaces of the knife clamping plate extends to a position close to the fabric, which greatly reduces the suspended length of the cutter and provides better protection for the twisting of the cutter. While correcting the problem of easy cutter breakage, it also protects the cutter from easy deviation, making the cut fabric more accurate.

[0015] The film covering openings that pass through the upper and lower surfaces of the knife clamping disc allow the film on the automatic cutting bed to pass through this opening to re-cover the cut fabric, thereby achieving the effects of energy saving, pressure maintenance and instant re-sealing of highly elastic fabrics, solving the problem of being unable to mass-produce those highly elastic and difficult-to-cut fabrics.
