Description

Technical Field

[0001] This utility model relates to the field of mask cutting technology, specifically a mask processing cutting device with a waste collection mechanism. Background Technology

[0002] Ultrasonic roller cutting machines utilize the principle of instantaneous heat generation through ultrasonic vibration and friction. Under the pressure of a cylinder, the mask cutting roller contacts the ultrasonic vibration surface, thereby achieving the effects of cutting, welding, or perforating. The cut or perforated edges are automatically sealed, preventing blackening, scorching, hardening, or fraying, and providing a comfortable feel and excellent sealing effect. Using mask cutting rollers to cut masks not only allows for one-time forming but also offers high production efficiency.

[0003] Existing ultrasonic roller cutters feed a complete piece of fabric into the machine when cutting masks. After being cut, the fabric is shaped into a mask in the middle. As the fabric passes the tail of the cutter, it falls along with the cut mask, resulting in waste fabric that cannot be separated from the mask and requires manual sorting. To address this, we propose a mask-making cutting device with a waste collection mechanism. Utility Model Content

[0022] 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.

[0023] Reference Figures 1 to 5 This utility model provides a technical solution: a cutting device for mask processing with a waste collection mechanism, including a support platform 16, support legs 17 at the four corners of the bottom of the support platform 16, and an ultrasonic roller cutting device at the top of the support platform 16. Figure 1 and Figure 4As shown, the specific structure of the ultrasonic roller cutting device includes an installation port 22 opened on the support platform 16, and a pressing device and an ultrasonic generating device respectively set on the upper and lower sides of the installation port 22. First, the pressing device needs to be explained. Its specific structure includes a U-shaped frame 15 with the opening facing downwards. During installation, the two ends of the bottom of the U-shaped frame 15 are connected to the support platform 16 respectively. A U-shaped seat 28 with the opening facing downwards is provided inside the U-shaped frame 15. A mask cutting roller 25 is provided inside the U-shaped seat 28. The two ends of the mask cutting roller 25 are rotatably connected to the two ends of the U-shaped seat 28 respectively. One end of the mask cutting roller 25 is connected to the drive mechanism. Under the drive of the drive mechanism, the mask cutting roller 25 rotates. Next, a cylinder 14 is vertically installed at the top center of the U-shaped seat 28. The top of the cylinder 14 is connected to the U-shaped frame 15. The cylinder 14 can drive the U-shaped seat 28 to move up and down in a straight line. In order to make the up and down movement of the U-shaped seat 28 more stable, at least two guide support shafts 13 are also provided on one side of the cylinder 14, which are parallel to it. The guide support shafts 13 are movably installed in the U-shaped frame 15, and the top of the guide support shafts 13 is installed on the connecting seat 12. In this way, the top of all the guide support shafts 13 is fixed, and they can provide support when the U-shaped seat 28 moves up and down in a straight line, making the U-shaped seat 28 more stable. like Figure 2 and Figure 4 As shown, the drive mechanism that drives the mask cutter roller 25 to rotate specifically includes a second motor 11 set on the top of the connecting seat 12. Both the rotating shaft of the second motor 11 and one end of the mask cutter roller 25 are provided with sprockets. The two sprockets are connected by a transmission chain. In order to prevent the transmission chain from touching the U-shaped frame 15, an opening 10 corresponding to the transmission chain is provided on the U-shaped frame 15, allowing the transmission chain to pass through the opening 10.

[0024] Secondly, the ultrasonic generator needs to be described. Its specific structure includes a mounting plate 18 located below the support platform 16. The four corners of the mounting plate 18 are connected to the support legs 17 to fix the mounting plate 18. A transducer 19 is provided at the bottom of the mounting plate 18. The top of the transducer 19 is connected to the amplitude transformer 20. The top of the amplitude transformer 20 is connected to the U-shaped bracket 24 with the opening facing the direction. A lower extrusion roller 23 is provided inside the top of the U-shaped bracket 24. The two ends of the lower extrusion roller 23 are rotatably connected to the U-shaped bracket 24. The lower extrusion roller 23 is placed inside the mounting opening 22 and is located directly below the mask cutting roller 25. It should be noted that the surface of the lower extrusion roller 23 is flush with the top surface of the support platform 16. In actual use, the transducer 19 is connected to the ultrasonic generator through a wire, so that the ultrasonic generator controls the operation of the transducer 19. The transducer 19 transmits ultrasonic vibration to the U-shaped bracket 24 through the amplitude transformer 20. Therefore, under the drive of the amplitude transformer, both the U-shaped bracket 24 and the lower extrusion roller 23 will generate ultrasonic vibration. To make the U-shaped bracket 24 more stable, at least one guide support rod 26 is provided at the bottom of the U-shaped bracket 24. The guide support rod 26 is parallel to the amplitude rod 20 and is movably arranged in the mounting plate 18.

[0025] Based on the above embodiments, it should be noted that the shearing device proposed in this application is only a part of the mask production equipment. The specific working process of the shearing device is as follows: Figure 5 As shown, when the fabric enters between the mask cutting roller 25 and the lower extrusion roller 23, ultrasonic vibration is generated between the lower extrusion roller 23 and the mask cutting roller 25, so that the mask cutting roller 25 cuts the fabric passing below it. To ensure that the upper and lower mask cutting rollers 25 and the lower extrusion roller 23 rotate synchronously, such as Figure 4 As shown, the end of the mask cutting roller 25 away from the drive mechanism is provided with a second gear 29, and the end of the lower extrusion roller 23 is provided with a first gear 27 corresponding to the second gear 29. When the mask cutting roller 25 is placed on the lower extrusion roller 23, the second gear 29 and the first gear 27 mesh, so when the mask cutting roller 25 rotates, it can simultaneously drive the lower extrusion roller 23 to rotate.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, two parallel guide shafts 9 are provided on the discharge side of the ultrasonic roller cutting device. Both ends of the guide shafts 9 are rotatably connected to supports 8, and the supports 8 are connected to the support platform 16. Figure 5 As shown, the fabric below the mask cutting roller 25 is cut and shaped. Since the shaped part of the mask needs to be removed from the original fabric, the fabric cut by the ultrasonic roller cutting device needs to pass through the guide shaft 9 from bottom to top, so that the shaped part in the middle of the fabric will automatically fall off, while the rest of the fabric will pass over the guide shaft 9. It should be noted that, because the fabric has been sheared by the mask cutting roller 25, the forming part of the mask has already separated from the fabric. When the fabric moves to below the guide shaft 9, as... Figure 5 As shown, the guide shaft 9 can bend the fabric, so the forming part of the mask will automatically separate from the middle of the fabric. To facilitate the collection of discarded fabric, a support 6 is vertically mounted on the top of the base 1. A winding shaft 4 rotatably mounts on the support 6. One end of the winding shaft 4 is driven to rotate by a drive device, which includes a first motor 2 mounted on the base 1. Both the shaft of the first motor 2 and the end of the winding shaft 4 near the first motor 2 are equipped with sprockets, connected by a transmission chain. Fabric passing through the guide shaft 9 is wound onto the winding shaft 4, as detailed below. Figure 5 As shown, a baffle 5 is provided at one end of the winding shaft 4 near the bracket 6, and a clamping seat 3 is threadedly installed at the other end of the winding shaft 4 away from the bracket 6. A winding drum is movably sleeved on the winding shaft 4, and the clamping seat 3 clamps and fixes the winding drum. The fabric is actually wound on the winding drum, which makes it convenient to replace the winding drum. like Figure 5 As shown, the top of the bracket 6 is equipped with a stop bar 7 that is parallel to the winding shaft 4. The fabric coming from the guide shaft 9 passes over the stop bar 7 and then winds onto the winding drum, which allows the fabric to be better supported.

[0027] In order to enable the rapid collection of the formed parts of the mask, such as Figure 1 As shown, a downward-sloping guide plate 21 is provided below the guide shaft 9. In actual use, such as... Figure 5 As shown, a container for taking masks can be placed below the guide plate 21.

[0028] 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.
