Description

Technical Field

[0001] This invention belongs to the field of cutting bed technology, specifically, it relates to a high-precision synchronous cutting device for multi-layer fabrics. Background Technology

[0002] Currently, traditional multi-layer fabric cutting devices use vacuum adsorption platforms and adjustable pressure plates to fix the fabric, which is then used in conjunction with the cutting device for cutting. While the vacuum adsorption platform can effectively fix the fabric and improve cutting accuracy, the adsorption effect is inconsistent due to differences in fabric thickness, material, and breathability during the multi-layer fabric cutting process, causing some fabric to still move during the cutting process. In addition, although the adjustable pressure plate can press the fabric tightly, the pressure distribution of the pressure plate is uneven, which causes the fabric to still misalign between layers when subjected to cutting force, resulting in unstable product quality and low production efficiency.

Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0031] One embodiment of this application provides a high-precision synchronous cutting device for multi-layer fabrics, such as... Figure 1 As shown, it includes: a frame 1, which serves as a support for the entire cutting device;

[0032] The fabric positioning unit is installed on the frame 1. The fabric positioning unit fixes and positions the multi-layer fabric to ensure that the multi-layer fabric does not move during the cutting process.

The cutting mechanism includes a cutting blade and a blade drive unit. The blade drive unit is connected to the frame 1. The cutting blade is connected to the movable end of the blade drive unit. The cutting blade is driven by the blade drive unit to realize the cutting of the multi-layer fabric. This structure and process are existing technologies and will not be described in detail.

[0034] The control system is connected to the frame 1. The tool drive unit is connected to the control system. The control system is used to control the movement speed and position of the cutting tool in the cutting mechanism to ensure that the multi-layer fabric is cut with high precision and synchronously during the cutting process.

[0035] A sensor group, connected to the frame 1, includes a first displacement sensor and a first pressure sensor. Both the first displacement sensor and the first pressure sensor are existing technologies, and their structures will not be described in detail. The first displacement sensor and the first pressure sensor are respectively connected to the control system. The first displacement sensor is used to monitor the displacement information of the cutting tool in real time, and the first pressure sensor is used to monitor the pressure change of the cutting tool during the cutting process in real time. The first displacement sensor and the second pressure sensor respectively feed back the obtained data to the control system to realize closed-loop control.

[0036] In one embodiment, the fabric positioning unit includes a vacuum adsorption platform and an adjustable pressure plate 3. The vacuum adsorption platform is mounted on the frame 1. The vacuum adsorption platform firmly adsorbs multiple layers of fabric onto the vacuum adsorption platform through negative pressure. The adjustable pressure plate 3 is connected to the frame 1 to press the multiple layers of fabric on the vacuum adsorption platform to prevent misalignment between the multiple layers of fabric during the cutting process.

[0037] In one embodiment, such as Figure 2 As shown, the vacuum adsorption platform includes a platform body 21, on which several independent adsorption units 22 are arranged at intervals. Each adsorption unit 22 is connected to the control system, which independently controls the several independent adsorption units 22 and divides them into different areas. According to the thickness and material of the multi-layer fabric, the adsorption force of each area can be independently adjusted to ensure that the multi-layer fabric can be uniformly and firmly adsorbed, thus solving the problem of adsorption accuracy.

[0038] In one embodiment, the surface of the vacuum adsorption platform is provided with a breathable adsorption layer, which is microporous silica gel, to improve the adsorption effect and reduce the impact of negative pressure suction on multi-layer fabrics.

[0039] In one embodiment, the adsorption unit 22 is a small vacuum pump or a suction cup. It should be noted that the small vacuum pump or suction cup adsorbs multi-layer fabrics through the principle of vacuum adsorption, which is existing technology and will not be described in detail here. For example, the suction cup is connected to a vacuum generator, and the vacuum negative pressure generated by the vacuum generator is transmitted through the suction cup to adsorb multi-layer fabrics.

[0040] In one embodiment, such as Figure 3As shown, each adsorption unit 22 is connected to a control valve 23 for controlling the adsorption state, which can independently control the adsorption state of each adsorption unit 22, such as adsorption or release; the adsorption force of each area can be adjusted as needed by the control valve 23 to achieve firm fixation of the multi-layer fabric; a second displacement sensor or a second pressure sensor is installed on each adsorption unit 22 to monitor the magnitude of the adsorption force of each adsorption unit 22 and the fixation state of the multi-layer fabric in real time; the second displacement sensor or the second pressure sensor feeds back the monitoring data to the control system for real-time adjustment; each adsorption unit 22 is connected to the control system through a communication line to receive instructions from the control system in real time and adjust its own adsorption state according to the instructions.

[0041] In this embodiment, each adsorption unit 22 is designed as a modular structure, and each adsorption unit 22 is independent and easy to disassemble and assemble; in this way, when a certain adsorption unit 22 needs maintenance or cleaning, it can be easily removed and processed separately without affecting the normal operation of other adsorption units 22.

[0042] In this embodiment, a dust cover or protective net is set around the vacuum adsorption platform to reduce the probability of dust and debris entering the adsorption unit 22; this can reduce the frequency of maintenance and cleaning, and at the same time extend the service life of the adsorption unit 22.

[0043] In one embodiment, in order to improve the adsorption effect of the adsorption unit 22, a heating device is also included to preheat the multi-layer fabric. The preheated multi-layer fabric is pressed by the adjustable pressure plate 3 to make it flatter and easier to adsorb and cut.

[0044] The heating device is built into a vacuum adsorption platform, which has a heating channel. The heating device includes a heater for supplying hot gas to the heating channel; the structure of the heater is existing technology and will not be described further. It also includes a hot gas transfer shroud 31 connected to a groove on the vacuum adsorption platform. Figure 3 As shown, the heating machine is connected to the bottom of the hot gas transmission cover 31 through the heating channel; the hot gas transmission cover 31 is fixed on the groove by the fixing plate 32, and the hot gas transmission cover 31 has a hot gas containing space, which is connected to the vacuum adsorption platform, and the hot gas in the hot gas containing space heats the vacuum adsorption platform.

[0045] In one embodiment, the heat transfer hood 31 is funnel-shaped to facilitate heat diffusion. The interior of the heat transfer hood 31 is provided with a first heat filter layer 33 and a second heat filter layer 34 arranged at intervals. The first heat filter layer 33 is located above the second heat filter layer 34. The first heat filter layer 33 is a nonwoven fiber layer with a plurality of pores, each pore consisting of a first through-hole with a diameter between 15-35 micrometers and a second through-hole with a diameter greater than 50 micrometers. The percentage of the number of first through-holes to the total number of pores is greater than 50%, and the percentage of the number of second through-holes to the total number of pores is less than 0.5%. The second heat filter layer 34 is a jet-sprayed short fiber layer to prevent impurities in the heat from adversely affecting the multi-layered fabric.

[0046] In this embodiment, a self-test program is added to the control system to periodically check the adsorption unit 22. If any abnormality is found, such as abnormal adsorption force or insufficient vacuum, the control system will automatically clean it or prompt the user to perform maintenance.

[0047] In this embodiment, the internal structure and channels of the adsorption unit 22 are made of materials that are easy to clean and do not easily attract dust, thereby reducing the difficulty of cleaning and further solving the technical problem of cleaning after adsorption.

[0048] In one embodiment, the adjustable pressure plate 3 is designed as a multi-point adjustable structure, that is, multiple independent pressure adjustment points are set on the pressure plate; by adjusting the pressure of each adjustment point, more uniform fabric pressing is achieved, reducing the possibility of interlayer misalignment; specifically, the adjustable pressure plate 3 includes a pressure plate body, on which a plurality of adjustment drive parts are provided at intervals, and a pressure head is connected to the free end of each adjustment drive part, and each adjustment drive part is connected to the control system; the pressure head is made of an elastic material, such as silicone or polyurethane, to increase the contact area with the fabric and provide a more uniform pressure distribution.

[0049] In one embodiment, an auxiliary fixing mechanism is also included. The auxiliary fixing mechanism is connected to the perimeter of the vacuum adsorption platform. The auxiliary fixing mechanism is a pneumatic gripper or a mechanical clamping device, which is existing technology and will not be described in detail here. For example, a mechanical gripper. The auxiliary fixing mechanism is adjusted according to the size and shape of the multi-layer fabric to provide additional fixing force to ensure that the multi-layer fabric does not move during the cutting process.

[0050] In this embodiment, the fabric positioning unit is integrated with the control system, and the fixation status of the multi-layer fabric is monitored in real time through displacement and pressure sensors. Once the multi-layer fabric is detected to have a tendency to move or loosen, the control system immediately adjusts the adsorption force of the vacuum adsorption platform, the pressure of the adjustable pressure plate 3, or the clamping force of the auxiliary fixing mechanism to maintain the stable positioning of the multi-layer fabric and solve the problem of pressure displacement.

[0051] As further explained, the tool drive unit adopts a servo motor, which is connected to the cutting tool through a reducer to realize high-speed and precise movement of the cutting tool.

[0052] As further explained, the control system uses a PLC controller, which receives feedback signals from the sensor group and adjusts the motion parameters of the cutting tool in real time to ensure high-precision synchronous cutting of multi-layer fabrics.

[0053] As a further explanation of the present invention, the first displacement sensor is a laser displacement sensor, which has the characteristics of high precision and non-contact measurement and can monitor the minute displacement of the cutting tool in real time; the first pressure sensor is a piezoelectric pressure sensor, which has the characteristics of high sensitivity and fast response and can monitor the pressure changes during the cutting process in real time.

[0054] This embodiment improves the stability and reliability of the fabric positioning unit through refined design schemes such as improving the vacuum adsorption platform, optimizing the adjustable pressure plate design, introducing auxiliary fixing mechanisms, and integrating an intelligent control system. This ensures precise positioning of multi-layer fabrics during the cutting process and prevents interlayer misalignment. By designing the adsorption unit as a modular structure, each unit is independent and easy to assemble and disassemble. Thus, when a unit requires maintenance or cleaning, the adsorption unit achieves more effective adsorption capacity through a heating device.
