Description

Technical Field

[0001] The invention relates to a computer cutting bed with a lifting bridge and automatic film lamination, which is mainly used for cutting various cloth (surface) materials. Background Art

[0002] The bridge height across the working surface of current computer cutting machines is fixed, and most of them are divided into 5 cm, 7 cm, 9 cm, 11 cm, etc. This structure brings many problems. For example, when cutting some airtight leather fabrics and canvas bag fabrics, due to the airtightness of the fabrics and the high density of the structure, only a small number of layers can be cut. In this way, the bridge needs to be lower from the working surface. Most computer cutting machines use a bridge 5 cm away from the working surface to ensure the cutting accuracy and avoid the problem of easy knife breakage caused by too long a cutter. When cutting some medium-thickness fabrics, because there are more layers, the bridge needs to be higher from the working surface. At this time, 7 cm or even 9 cm is mostly used. The computer cutting bed with a height of centimeters, the same problem mentioned above, is that it is difficult to cut leather and Oxford fabrics with this specification of computer cutting bed; and there are a lot of fluffy fabrics on the market, such as: various thermal fabrics compounded with fluffy cotton, napped fabrics for thermal clothing, non-falling velvet, coral fleece, various imitation wool fabrics, etc., because of their lightness and fluffiness, only a few twenty layers are already piled very high. Although the computer cutting bed can draw negative pressure to flatten the fabric to a few centimeters when working and complete the cutting, but because the computer cutting bed consumes a lot of energy when working, plus various consumables and labor costs when laying the cloth, it is very uneconomical to use only dozens of layers. As a result, computer cutting machines are rarely used to cut fluffy fabrics. If the number of layers of fluffy fabrics is increased, the fatal problem is that the machine cannot work directly, because there are several problems that cannot be solved. One is that the fabrics are piled too high. First of all, the computer cutting machine requires edge inspection when aligning the fabrics and the cutting machine. The fabrics are too high and the bridge is too low to pass through. Even the 11-centimeter cutting machines with higher specifications on the market cannot pass through. If the fabrics are pressed down by vacuum pumping, and the machine passes through and is found to be not properly placed (improperly placed fabrics are a common condition in daily work), then the machine must be returned and the fabrics must be moved again. Repeating this process several times consumes a lot of energy, because the vacuum pumping The motor usually has an installed capacity of 20 kilowatts. In order to allow the bridge to pass without stopping the machine, a lot of energy is wasted. The second problem is that even if the fabric is aligned and can be cut normally, due to the limited length of the cutting table working surface, it is necessary to feed the remaining fabric forward through the brush conveyor belt after cutting one layout, and the negative pressure needs to be removed when feeding the fabric forward, because when there is negative pressure, the fabric will be tightly pressed against the working surface by the strong negative pressure, causing the brush conveyor belt to be unable to rotate, and once the negative pressure is removed, the fabric will immediately return to its fluffy state and become very high and thick, and because the bridge is only about ten centimeters above the working surface, the fabric cannot pass the bridge and subsequent work cannot be carried out.

[0003] At present, various fabrics with good elasticity and high bulkiness in the market cannot be cut normally with computer cutting beds, unless the cost is not taken into account for cutting in a small number of layers. If you want to complete the cutting on a computer cutting bed without changing the bed, it is unlikely to be completed when the number of economical layers is large. Because for such fabrics with good elasticity and high bulkiness, after covering the fabric with an airtight film and compressing the fabric into a thickness that can be cut by vacuuming, when the cutter cuts the film and fabric, air will enter from the incision, and the original airtight film will lose the compression force formed by the negative pressure little by little. Under the rebound of the elastic fabric, the incision will slowly become larger and larger, resulting in lower and lower negative pressure. When the air intake is greater than the air extraction volume that the vacuum extraction machine can extract, the negative pressure will eventually fail completely, and all the fabrics will be restored to their original height, because the fabric is far higher than the bridge, so the computer cutting bed will not be able to work; so at present, for the above-mentioned fabrics with huge consumption and wide application, they are basically still cut by manual electric scissors.

[0004] In addition, the existing computer cutting machines mostly use gas cooling to cool the cutters. When cutting fabrics that are easily melted and stick together when exposed to heat (various chemical fiber fabrics), the cutter and the fabric need to rub up and down at high frequency during cutting, which will cause heat. Since the blade of the cutter is mostly buried in the fabric when working, gas cooling cannot cool the cutter when working, causing the chemical fiber fabrics to stick together due to the heat and melting of the cutter and cannot be cut.

[0005] In addition, there are a large number of airtight fabrics, such as various leathers and airtight coated waterproof fabrics. They are not only airtight but also made of chemical fiber. When they are cut with a computer cutting bed, only the upper layer of fabric is pressed onto the working surface of the computer cutting bed due to the negative pressure when the negative pressure box is pumping negative pressure. When the top layer of fabric and the covering film are cut, the negative pressure disappears (because it is an airtight fabric). Unlike breathable fabrics, each layer will not have air pumped out and each layer will have a sense of negative pressure. Once cut, the fabric is easy to move because it loses the effect of negative pressure, resulting in inaccurate cutting and easy to damage. Therefore, the computer cutting bed can only cut a small number of layers of leather fabrics, and it is even more powerless for those waterproof fabrics that are thinner, slippery, and easily scalded and stuck (raincoats, rain ponchos, assault jackets, etc.).

[0006] There are also current computer cutting beds, because a large amount of debris generated when cutting fabrics will fall into the brush conveyor belt, and the brush conveyor belt is an indispensable working surface for computer cutting beds. When the cutter is cutting the fabric, the cutter will extend into the brush conveyor belt to complete the cutting of the fabric. When the cutter extends into the brush conveyor belt to cut the fabric irregularly front, back, left and right, the bristles of the clean brush conveyor belt will have space to move left and right. Even if they are touched by the cutter, they will slide to the side by themselves and will not be easily cut off by the cutter. It can be used as the working surface of the computer cutting bed for a long time, and when the fabric debris generated during cutting continuously falls into the brush and gradually fills the gaps between the brushes, When the brush hits the cutter again, the gap next to it has been filled with debris, and the brush cannot slide to the side and is cut off by the cutter. This cycle is repeated, and the brush is damaged more and more, causing the working surface of the cutting table to be no longer flat. When the fabric is laid on it, if the working surface is not flat, the fabric will bend, pile up and deform there, and the cut workpiece will have a large error and cannot be accurately spliced ​​and combined with other workpieces. Therefore, when the working surface of the brush is not flat, it needs to be removed and replaced. Not to mention the high cost of the brush, and replacing the brush is a time-consuming and laborious task, which not only wastes time, but also makes the brush a consumable part, which wastes time and money, and increases the cost of using the computer cutting table.

The bottom sealing plate of the negative pressure box body is inclined to one end, and the inclination angle is between 2-86 degrees (measured from the low to the high). An ash outlet is opened at the lower position of the bottom sealing plate, and the ash outlet can be opened and closed. When cleaning, the ash outlet is opened to take out debris, and the ash cleaning port is closed again when cleaning is completed. There is more than one blowing port at the high position of the bottom sealing plate, and the air inlet pipe is provided with a switch device; the bottom sealing plate can be inclined from one end to the other end, one side to the other side, both sides (two ends) to the middle or all around to the middle, and vice versa. It can also be inclined from the middle to all around or both sides (two ends); the purpose of the inclination is to collect the debris cleaned from the brush conveyor belt to the ash outlet through the slope and the blowing device for easy cleaning. Beneficial Effects

[0025] By adding the function of lifting the bridge beam through design, fluffy fabrics that could not be cut in batches before can be mass-produced like other fabrics, thereby improving production efficiency, reducing labor costs and improving cutting accuracy. It is also able to adapt to the limitations of the bridge height required for fabrics of various thicknesses, and one machine can solve the limitation of the single specification of existing computer cutting beds due to the fixed bridge height.

[0026] The energy consumption of computer cutting machines has always been a problem that cannot be ignored. Because of the need to extract negative pressure, large motors of up to 20 kilowatts are configured. Because of the air leakage caused by the fabric being cut, although the existing computer cutting machines have a large-area film covering device, during production, because the fabric needs to be cut back and forth, when it runs back, the large-area covering device is reopened and leaks occur. This is repeated, resulting in the high-power negative pressure extraction machine running at almost full power without stopping, resulting in a large electricity cost; the present invention can instantly cover the cut edge with a film strip and be sucked by negative pressure, and it is an independent cover cut, which can cover the length of the cut edge, and will not reopen the cut edge due to the back and forth operation when cutting the fabric, so the air leakage loss is very small, so that the negative pressure extraction machine can be maintained at a small load operation, and can even be stopped and started intermittently within a certain range, which can save a lot of energy consumption costs and machine losses; while saving energy, it also solves the problem that those highly elastic and fluffy fabrics mentioned in the background technology cannot be mass-produced.

[0027] When the existing computer cutting machine is changing beds for cutting, the brush conveyor belt as a working table needs to rotate forward. In order to prevent the movement of the fabric, it needs to rotate forward with a slight negative pressure. At this time, because the mounting strip of the brush conveyor belt and the longitudinal support frame in the negative pressure box are moved by the friction of metal against metal, this not only causes the noise generated by abnormal noise, but also causes the wear of the brush mounting strip, which becomes a wearing part. The present invention can not only solve the abnormal noise and reduce the wear by installing arranged rollers on the longitudinal support frame, but also add a group of inner circulation conveyor belts on the inner circumference of the brush conveyor belt, which can better protect the brush conveyor belt from the noise and wear problem when it rotates. More importantly, when the computer cutting machine is in a high negative pressure working state while cutting and rotating, the synchronous rotation of the inner circulation conveyor belt and the brush conveyor belt solves the wear and resistance problem caused by the high negative pressure when the computer cutting machine is cutting and rotating.

[0028] The existing computer cutting machine adopts air cooling technology, which causes the cutter to fail to cool down during operation and causes friction and heating, and it is impossible to cut those easily fusible chemical fiber fabrics; the present invention adopts a liquid cooling solution, and cools the cutter through a controllable liquid flow device, which effectively reduces the temperature of the cutter and solves the problem of melting and sticking of chemical fiber fabrics; in addition, the design of the cutter assembly can increase the stroke of the cutter during up and down cutting by adjusting the fulcrum position of the No. 1 connecting rod, and reducing the cutting frequency can also greatly reduce the degree of heating of the cutter.

[0029] When cutting those airtight and slippery chemical fiber and leather fabrics, the current computer cutting machine can only cut a relatively small number of layers because of the airtight characteristics of the fabrics and poor adsorption capacity to prevent the fabrics from moving, and cannot be mass-produced. It is even more difficult to cut slippery fabrics such as raincoats, rain capes, and assault jackets. The rotary clamping knife disc assembly of the present invention is equipped with a universal ball bearing under the clamping knife disc, and cooperates with the automatic laminating device described above. When cutting the above difficult-to-cut fabrics, firstly, a stable negative pressure can be maintained to press the fabrics firmly on the working surface, and then the height of the rotary clamping knife disc can be adjusted to allow the universal ball bearing under the clamping knife disc to press the fabric with appropriate force, so as to prevent the cutter from turning up the fabric belt when cutting up and down, thereby solving the problem that these fabrics are difficult to cut in batches.
