Description

Technical Field

[0001] The utility model relates to the technical field of fabric cutting detection, in particular to a device for detecting knife deviation during the cutting process of multi-layer fabrics. Background Art

[0002] Multi-layer cutting is to spread multiple layers of fabric on the bristle bed at the same time, and cut the fabric with a vibrating knife after vacuum adsorption, so that all the fabrics can be cut at one time. During the cutting process, when the cutting height after adsorption is too high, the two sides of the knife bear different pressures, resulting in non-verticality (knife deviation), so a knife deviation detection device is needed for real-time detection. The knife deviation detection device usually uses a physical contact sensor, which is installed in the knife disc groove on both sides of the knife. When the knife is offset, the sensor on one side senses the distance change. The sensor senses the signal and transmits the signal. The program responds in time to control the knife swing, thereby achieving deviation correction.

[0003] However, the contact sensor contact method device mainly used in the existing technology is difficult to install, and the head structure must be specially designed, otherwise the device will be difficult to function, and the contact device has poor accuracy, sensitivity, stability, and durability. When in use, the contact sensor is easily damaged when the knife vibrates at high speed. At the same time, the contact method has a longer response time due to the physical travel of the spring and gasket.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a device for detecting knife deviation during the cutting process of multi-layer fabrics is provided. Utility Model Content

When the knife is stationary, the distance measured by the high-precision distance measuring sensor 1 is the standard distance. A distance greater than this distance indicates a deviation to one side, and a distance less than this distance indicates a deviation to the other side.

A knife disc perforation 2 is provided inside the knife disc 1. The outlet width of the lower end of the knife disc perforation 2 is greater than the outlet width of the upper end, and the outlet width of the lower end of the knife disc perforation 2 is 3-10 mm. The knife disc perforation 2 is used for installing a vibrating knife 3. Its upper small and lower large setting makes the vibrating knife 3 have enough space for the knife to deviate, which is convenient for detection. The vibrating knife 3 is provided inside the knife disc perforation 2. The detection component 6 for efficient and anti-interference detection of knife deviation is provided inside the lower end of the knife disc 1. The detection component 6 includes a mounting groove 601 and a high-precision distance measuring sensor 602. A high-precision distance measuring sensor 602 is provided inside the mounting groove 601. The mounting groove 601 and the knife disc 1 are an integrated structure. The size of the mounting groove 601 is based on the sensor size and the physical structure requirements of the knife disc. The high-precision distance measuring sensor 602 detects The signal is transmitted facing the side of the knife. Since the knife direction and the sensor rotate synchronously with the cutter disc 1, the sensor detection signal is always facing the side of the knife. As the knife wears, it needs to be replaced when it reaches half the initial knife diameter. A fixed groove 4 is provided on the side of the lower surface of the cutter disc 1, and a high-precision distance sensor 2 5 is provided inside the fixed groove 4. The high-precision distance sensor 1 602 and the high-precision distance sensor 2 5 are detected in a non-contact manner. The module is wear-free, the detection efficiency is high, the sensitivity will not be reduced due to loss, and the service life is long. It can also eliminate inaccurate measurement accuracy caused by physical structure, metal fatigue, knife properties, debris, wear and tear, etc. At the same time, the high-precision distance sensor 2 5 faces the half position close to the side of the knife back. When the knife is stationary, the distance measured by the high-precision distance sensor 2 5 is the standard distance. A distance greater than this distance represents a deviation to one side, and a distance less than this distance represents a deviation to the other side.

[0021] like Figure 3 As shown, an auxiliary component 7 for laying useful lines is provided on the side of the installation groove 601, and the number of auxiliary components 7 is set in two groups. The auxiliary component 7 includes an auxiliary groove 701 and a power supply and signal transmission cable 702, and the interior of the auxiliary groove 701 is provided with a power supply and signal transmission cable 702. The auxiliary groove 701 makes it convenient to route and install the power supply and signal transmission cable 702 on the cutter head 1, and increases the neatness of the line. The installation groove 601 and the auxiliary groove 701 are connected to each other, and the auxiliary groove 701 and the power supply and signal transmission cable 702 are snap-connected.

[0022] In summary, the deflection knife detection device in the multi-layer fabric cutting process first Figure 1-Figure 3The structure shown in the figure is that the cutter disc 1 is installed on the fabric cutting machine through the cutter connecting frame, and the vibrating knife 3 is installed in the cutter disc perforation 2. The structure of the cutter disc perforation 2 being small at the top and large at the bottom allows the vibrating knife 3 to have enough space for the knife to deviate, and then the high-precision distance sensor 1 602 (model DT2-35V15) and the high-precision distance sensor 2 5 (model DT2-35V15) are respectively installed in the corresponding installation slots 601. At the same time, the auxiliary slot 701 is on the cutter disc 1, which makes it easy to install the power supply and signal transmission cable 702, thereby increasing the neatness of the line. When the vibrating knife 3 is cutting, the high-precision distance sensor 1 602 detects that the signal is emitted facing the side of the knife. Due to the direction of the knife and the sensor and The cutter disc 1 rotates synchronously, so the sensor detection signal is always facing the side of the cutter. As the cutter wears, it needs to be replaced when it reaches half the initial cutter diameter. At the same time, the high-precision distance measuring sensor 25 is facing the half position close to the side of the cutter back. When the cutter is stationary, the distance measured by the high-precision distance measuring sensor 25 is the standard distance. A distance greater than this distance represents a right deviation (in the direction of the cutter edge), and a distance less than this distance represents a left deviation. The high-precision distance measuring sensor 1602 and the high-precision distance measuring sensor 25 are detected in a non-contact manner. The module is wear-free, the detection efficiency is high, the sensitivity will not be reduced due to loss, the service life is long, and it can also eliminate inaccurate measurement accuracy caused by physical structure, metal fatigue, cutter properties, debris, wear and tear, etc.
