Description

Technical Field

[0001] This utility model relates to the field of mask cutting technology, specifically a non-woven fabric cutting device for mask production with automatic feeding capability. Background Technology

[0002] A laser fabric cutting machine is a device that uses laser technology to cut fabric. Its core lies in a high-energy-density laser beam that precisely irradiates the fabric surface, instantly melting or vaporizing it to achieve a cut. Unlike traditional machining, laser cutting does not require contact with the fabric, avoiding deformation problems caused by contact between the cutting tool and the fabric. Laser fabric cutting machines are also used in the mask cutting industry, as they can operate continuously and offer high cutting precision.

[0003] However, current laser fabric cutting machines require the fabric to be laid out on the bed before cutting, and cannot automatically feed the fabric, thus reducing cutting efficiency. For example, the specification of a cutting device for producing willow-leaf shaped masks, as proposed in document number "CN219986548U", describes in section

[0043] that when there is raw material to be cut, the operator first places the raw material on the upper part of the cutting device body, then rotates the bidirectional lead screw, which drives two sliding blocks to move in opposite directions. At the same time, the guide rod makes the sliding blocks move more smoothly. When it moves to the appropriate position, the adjusting handle is rotated, which makes the fixed plate move downward. At the same time, the limiting plates on both sides make the two ends of the fixed plate evenly stressed, achieving the effect of pressing the raw material flat. This cutting process requires picking up the cut mask and fabric together from the bed, and then laying the new fabric again, which greatly reduces the efficiency of mask cutting. To address this, we propose an automatic feeding non-woven fabric cutting device for mask production. Utility Model Content

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 5This utility model provides a technical solution: an automatic feeding non-woven fabric cutting device for mask production, including a support bed 1, with a conveyor 2 installed at one end of the support bed 1. The conveyor 2 can be a belt conveyor, a mesh chain conveyor, or a chain plate conveyor. A three-axis robot 12 is installed above the conveyor 2, mounted on the top of the support bed 1, and a laser cutter 11 is installed on the free end of the three-axis robot 12. The conveyor 2 is within the working area of ​​the three-axis robot 12, allowing the three-axis robot 12 to drive the laser cutter 11 to any point on the surface of the conveyor 2.

[0023] Next, two parallel support rollers 8 are installed at the top of the end of the support bed 1 furthest from the conveyor 2. Both ends of the support rollers 8 are rotatably connected to the support bed 1, specifically by rotatably mounting both ends of the support rollers 8 in bearing seats, which are then installed on the support bed 1. One end of each of the two support rollers 8 is driven to rotate by the same drive device. Figure 1 and Figure 3 As shown, the driving device includes a first drive motor 5, which is installed below the support bed 1. The first drive motor 5 and one end of the support roller shaft 8 are respectively provided with double-row sprockets. The double-row sprockets are connected by a transmission chain. So when the first drive motor 5 rotates, the first drive motor 5 can drive the two support roller shafts 8 to rotate synchronously.

[0024] A certain gap is provided between the two support rollers 8 to ensure that they do not contact each other. This also increases the placement space between the two support rollers 8, because in actual use, the fabric roll needs to be placed on the two support rollers 8, and the gap between the two support rollers 8 can accommodate fabric rolls with larger diameters. To make the fabric roll more stable, such as... Figure 3 As shown, two annular baffles 20 are movably fitted on each support roller shaft 8. An annular seat 6 is movably fitted on one side of the annular baffle 20 and is coaxially mounted on the support roller shaft 8. The annular seat 6 is provided with fasteners, which are bolts threaded onto the annular seat 6. Tightening the bolts can position the annular seat 6, thereby adjusting the position of the annular baffles 20. In actual use, the fabric roll is placed between the annular baffles 20 to prevent the fabric roll from shifting.

[0025] like Figure 5 As shown, the rotation speed of the support roller 8 should match the rotation speed of the conveyor 2. When the support roller 8 rotates, it can drive the fabric roll to rotate, thereby allowing the fabric roll to be gradually unloaded. The free end of the fabric is placed on the conveyor 2, allowing the conveyor to deliver the fabric to the working area of ​​the three-axis robot 12. However, there is a slight distance between the support roller 8 and the conveyor 2. Therefore, to prevent the fabric from settling, a pressing drive mechanism is installed above the end of the conveyor 2 near the support roller 8. Figure 2As shown, the pressing drive mechanism includes a U-shaped frame 16 with its opening facing downward and both ends connected to the support bed 1. A lifting mechanism is provided in the middle of the top surface of the U-shaped frame 16. The lifting mechanism includes a cylinder 15 vertically installed in the middle of the U-shaped frame 16. Guide shafts 14 are provided parallel to each other on both sides of the cylinder 15. The guide shafts 14 are movably connected to the U-shaped frame 16. Specifically, the guide shafts 14 are movably placed in the guide seat, and then the guide seat is installed on the U-shaped frame 16.

[0026] A horizontal support beam 10 is provided below the U-shaped frame 16. The support beam 10 is connected to the lifting mechanism. Specifically, the guide shaft 14 and the free end of the cylinder 15 are connected to the support beam 10 respectively, allowing the cylinder 15 to extend and retract, thereby driving the support beam 10 to move up and down. A pressure roller 9 is provided parallel below the support beam 10. The two ends of the pressure roller 9 are rotatably installed in the support 7, and the top of the support 7 is connected to the support beam 10. Figure 1 and Figure 2 As shown, a second drive motor 13 is provided at the top of one end of the support beam 10. Both the second drive motor 13 and the pressure roller 9 are provided with sprockets at one end. The two sprockets are connected by a chain. When the second drive motor 13 rotates, it can drive the pressure roller 9 to rotate.

[0027] It should be emphasized that the rotation speed of the pressure roller 9 is the same as that of the conveyor 2. When the pressure roller 9 is placed on the conveyor 2, the conveyor 2 and the pressure roller 9 clamp the fabric, and then the pressure roller 9 and the conveyor 2 together drive the fabric forward, which can prevent the fabric from settling.

[0028] Furthermore, such as Figure 4 As shown, at least one guide rod 17 is provided between the support roller shaft 8 and the conveyor 2. Both ends of the guide rod 17 are rotatably connected to the support bed 1, as shown below. Figure 5 As shown, the fabric passes under the guide rod 17. When there are multiple guide rods 17, the fabric bends in an S-shape as it passes under the guide rods 17. The guide rods 17 can guide the fabric to the pressure roller 9, and the guide rods 17 can also flatten the fabric.

[0029] There is a certain gap between the guide rod 17 and the support roller shaft 8. This prevents the fabric from being directly clamped by the conveyor 2 and the pressure roller 9 when it comes out of the fabric roll. This gap is used for cushioning the fabric, allowing it to self-adjust during unloading. Figure 4 As shown, a strip frame 19 is provided between the guide rod 17 and the support roller shaft 8, and a detector 18 is provided in the middle of the strip frame 19. The strip frame 19 is located below the guide rod 17 and the support roller shaft 8.

[0030] It should be noted that during the actual fabric feeding process, the feeding speed should be slightly greater than the conveying speed of conveyor 2. This can prevent the fabric from being pulled, such as... Figure 5The dotted line indicates that when the fabric is laid to a certain length, the fabric between the guide rod 17 and the support roller shaft 8 will sink and bend. The sinking fabric will be placed on the detector 18, and the state of the fabric at this time will be sensed by the detector 18.

[0031] This application also includes a control cabinet 3, which contains a controller, which is either a host or a PLC logic controller. The controller is connected to the first drive motor 5 and the detector 18. When the detector 18 senses the fabric settling, the first drive motor 5 stops moving. The detector 18 is a distance detector, such as a laser distance detector or an ultrasonic distance detector, which mainly detects the distance between the fabric and the detector. When the fabric settles to a preset value, the first drive motor 5 stops. When the fabric height rises to a certain level, the first drive motor 5 continues to rotate to release the fabric, thereby achieving the balance of releasing the fabric.

[0032] The controller is also connected to the conveyor 2, laser cutter 11, second drive motor 13, and cylinder 15, respectively. This allows the controller to control each component individually, ensuring each component operates according to a pre-defined pattern. Figure 1 and Figure 4 As shown, an operation panel 4 is also installed on one side of the supporting bed 1 via a bracket. The operation panel 4 is connected to the controller, and the device can be operated through the operation panel 4.

[0033] Based on the above embodiments, when this application is used, such as Figure 5 As shown, the fabric roll is placed on the support roller shaft 8. The fabric roll is steadily released as the support roller shaft 8 rotates. The released fabric is pressed under the pressure roller 9. Then, the rotating pressure roller 9 and the conveyor 2 together transport the fabric forward, allowing the fabric to travel into the working area of ​​the three-axis robot 12. Then, the three-axis robot 12 drives the laser cutter 11 to cut the fabric. The cut mask falls down with the conveyor. Therefore, in actual use, a container for collecting masks can be placed at the end of the support bed 1. It should be noted that the operator should separate the waste fabric and masks to avoid them piling up together.

[0034] Based on the above embodiments, further optimizations can be made to prevent the gears at the end of the support roller shaft 8 from being exposed, such as... Figure 2 As shown, a sealing cover can be installed at the end of the support roller shaft 8 to seal the gear set and prevent foreign objects from being rolled into the gear.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
