Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a cutting machine for mask production. Background Technology

[0002] The technological development of cutting machines for mask production is closely linked to the core needs of large-scale mask production for cutting precision, processing efficiency, and material compatibility, forming a positive trend of coordinated advancement with the progress of epidemic prevention material manufacturing technology. In the industrial production of masks, the forming of various products such as flat masks and KN95 masks highly depends on the stable performance of the cutting process.

[0003] However, existing mask cutting machines have the following drawbacks:

[0004] (1) In the existing cutting machines, the degree of automation is insufficient, and most of them rely on manual assistance to complete the cutting action. Operators need to manually push the fabric to the cutting position or adjust the fabric tension in real time during the cutting process. This not only increases labor costs, but also makes it difficult to ensure that the cutting rhythm of each mask fabric is consistent. The fabric cutting size is prone to fluctuation due to deviation in the human operation rhythm, which affects the connection accuracy of subsequent welding, forming and other processes.

[0005] (2) The existing blade adjustment methods of cutting machines are limited and cannot flexibly adapt to the cutting needs of different sizes of fabrics. The blade position of some equipment is fixed. If the cutting size needs to be changed, the blade needs to be disassembled and the installation position recalibrated. The operation steps are cumbersome and time-consuming. Even some equipment with adjustable blades has a narrow adjustment range. In addition, the machine needs to be stopped multiple times for measurement and calibration during the adjustment process. It is difficult to achieve rapid and accurate movement and adjustment of the blade, resulting in low efficiency when switching between different specifications of masks and difficulty in meeting the flexible production needs of small batches and multiple varieties.

[0006] Therefore, this utility model provides a cutting machine for mask production. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem solved by this utility model is to provide a highly practical cutting machine for mask production, which solves the problems of insufficient automation and limited blade adjustment methods in existing cutting machines mentioned in the background art.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: A cutting machine for mask production includes a base plate, an operating table fixedly connected to the top of the base plate, a groove formed on the surface of the operating table, a dual-axis motor fixedly connected to the inner wall of the groove, a first transmission rod splinedly connected to the output end of the dual-axis motor, a first threaded rod fixedly connected to one end of the first transmission rod, an internal threaded block threadedly connected to the surface of the first threaded rod, a cutting blade fixedly connected to the top of the internal threaded block, a support rod fixedly connected to the top of the base plate, a movable plate fixedly connected to the top of the support rod, a groove formed at the bottom of the movable plate, one side of the cutting blade slidably connected to the inside of the groove, and a threaded groove formed on the surface of the movable plate. The system has a threaded hole with a second threaded rod internally connected to it. A turntable is fixedly connected to the top of the second threaded rod, and a rotating cylinder is threadedly connected to the bottom of the second threaded rod. A limit plate is fixedly connected to the bottom of the rotating cylinder. A circular hole is provided on one side of the limit plate, and a pressure roller is rotatably connected inside the circular hole. A driven wheel is fixedly connected to the surface of the pressure roller. A motor support is fixedly connected to the other end of the base plate. A motor housing is fixedly connected to the top of the motor support. A motor is fixedly connected to the inner wall of the motor housing. A second transmission rod is splined to the output end of the motor. A roller shaft is fixedly connected to one end of the second transmission rod, and a rotating wheel is fixedly connected to the surface of the roller shaft. A protective side plate is rotatably connected to the other side of the roller shaft.

[0011] Optionally, a handle is fixedly connected to the top of the turntable. The handle and the turntable are integrally formed. The integrally formed structure can enhance the connection strength between the handle and the turntable and reduce the risk of loosening after long-term use.

[0012] Optionally, the surface of the throttle is fitted with an anti-slip sleeve made of rubber. The elasticity of the rubber material can improve the comfort of gripping, and the fine texture on its surface can effectively prevent slippage when the hands are sweaty.

[0013] Optionally, a directional wheel is fixedly connected to the bottom of the movable plate. The directional wheel rolls on the operating table. The guiding nature of the directional wheel can prevent the fabric from shifting during movement and ensure the positioning accuracy of the cutting knife.

[0014] Optionally, a sliding bearing is fixedly connected to one side of the limiting plate. The inner hole of the sliding bearing is adapted to the outer diameter of the pressure roller, which enables the limiting plate to slide smoothly along the guide rod and reduces frictional loss between the two.

[0015] Optionally, a baffle is fixedly connected to the top of the operating table. The height of the baffle is higher than the table surface, and its edge is designed with a rounded transition. This not only prevents fabric scraps generated during cutting from splashing outside the operating table and keeping the production environment clean, but also limits the edge of the fabric during conveying, preventing the fabric from deviating and affecting the cutting accuracy.

[0016] (III) Beneficial Effects

[0017] This utility model provides a cutting machine for mask production, which has the following advantages:

[0018] 1. This mask production cutting machine, when cutting mask fabric, rotates the second threaded rod with a turntable, which drives the limit plate to move up and down through the rotating drum, adjusting the distance between the pressure roller and the operating table to accommodate fabrics of different thicknesses; the motor drives the roller shaft to rotate, and the cooperation between the rotating wheel and the driven wheel achieves stable fabric conveying; the protective side plate can isolate the rotating parts and improve operational safety; the overall structure has multiple adjustable designs to meet the production needs of various specifications of masks, improving the versatility and ease of operation of the equipment.

[0019] 2. This mask production cutting machine, when needing to adapt to mask fabrics of different widths, starts with a dual-axis motor that drives the first threaded rod to rotate via the first transmission rod. This causes the internal threaded block to move the cutting blade smoothly along the slide groove of the movable plate, achieving automated cutting and reducing errors caused by manual intervention. At the same time, the pressure roller at the bottom of the limit plate can compact the fabric before cutting, which, in conjunction with the movement trajectory of the cutting blade, ensures that the cutting size of each piece of mask fabric is uniform, improves the product qualification rate, and avoids material waste.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4This utility model provides a technical solution: a cutting machine for mask production, including a base plate 1, an operating table 2 fixedly connected to the top of the base plate 1, a groove on the surface of the operating table 2, a dual-axis motor 3 fixedly connected to the inner wall of the groove, a first transmission rod splinedly connected to the output end of the dual-axis motor 3, a first threaded rod 4 fixedly connected to one end of the first transmission rod, the first threaded rod 4 converts the rotational power of the dual-axis motor 3 into the linear motion of the internal threaded block 5 through threaded engagement with the internal threaded block 5, thereby driving the cutting blades 6 to move in position, thereby adjusting the spacing between the cutting blades 6 to meet the cutting needs of mask fabrics of different sizes, the surface of the first threaded rod 4 is threaded... The base plate 1 is connected to an internally threaded block 5, with a cutting blade 6 fixedly connected to its top. A support rod 7 is fixedly connected to its top, and a movable plate 8 is fixedly connected to its top. A groove is formed at the bottom of the movable plate 8, and one side of the cutting blade 6 is slidably connected inside the groove. A threaded hole is formed on the surface of the movable plate 8, and a second threaded rod 9 is threadedly connected inside the threaded hole. A turntable 10 is fixedly connected to the top of the second threaded rod 9, and a rotating cylinder 11 is threadedly connected to the bottom of the second threaded rod 9. The rotating cylinder 11 serves as a connecting transition component between the second threaded rod 9 and the limiting plate 12, converting the rotational motion of the second threaded rod 9 into the vertical linear motion of the limiting plate 12. Meanwhile, its threaded connection structure allows the second threaded rod 9 to rotate, and through its fixed relationship with the limiting plate 12, drive the limiting plate 12 to precisely adjust its height, thereby controlling the pressing force of the pressure roller 13 on the fabric, adapting to the conveying and cutting needs of fabrics of different thicknesses. The bottom of the rotating drum 11 is fixedly connected to the limiting plate 12, and a circular hole is opened on one side of the limiting plate 12. The pressure roller 13 is rotatably connected inside the circular hole. The surface of the pressure roller 13 is fixedly connected to the driven wheel 14. The other end of the base plate 1 is fixedly connected to the motor support base 15. The top of the motor support base 15 is fixedly connected to the motor housing 16. The inner side wall of the motor housing 16 is fixedly connected to the motor 17. The output end of the device is splinedly connected to a second transmission rod. The second transmission rod serves as a power transmission component between the motor 17 and the roller shaft 18. It can stably transmit the rotational power of the motor 17 to the roller shaft 18, causing the roller shaft 18 and the rotating wheel 19 on its surface to rotate synchronously. The rotating wheel 19 can cooperate with the driven wheel 14 on the surface of the pressure roller 13 to form a transmission relationship, thereby realizing continuous and uniform feeding of the mask fabric, providing a stable material supply for the subsequent cutting process, and ensuring the matching of the fabric feeding speed and the cutting speed. One end of the second transmission rod is fixedly connected to the roller shaft 18, the surface of the roller shaft 18 is fixedly connected to the rotating wheel 19, and the other side of the roller shaft 18 is rotatably connected to the protective side plate 20.

[0027] A handle 21 is fixedly connected to the top of the turntable 10. The handle 21 enhances the connection strength between the handle 21 and the turntable 10, reduces the risk of loosening after long-term use, and facilitates workers to adjust the height of the pressure roller 13 to adapt to fabrics of different thicknesses.

[0028] The surface of the throttle 21 is fitted with an anti-slip sleeve 22. The anti-slip sleeve 22 can improve the comfort of gripping, and its fine texture can effectively prevent slipping when the hands are sweaty.

[0029] The bottom of the movable plate 8 is fixedly connected with a directional wheel 23. The directional wheel 23 can prevent the fabric from shifting during movement and ensure the positioning accuracy of the cutter 6.

[0030] A sliding bearing 24 is fixedly connected to one side of the limiting plate 12. The sliding bearing 24 enables the limiting plate 12 to slide smoothly along the guide rod, reducing frictional loss between the two.

[0031] A baffle 25 is fixedly connected to the top of the operating table 2. The baffle 25 can prevent fabric scraps generated during cutting from splashing outside the operating table 2, keeping the production environment clean, and can also limit the edge of the fabric during conveying, preventing the fabric from deviating and affecting the cutting accuracy.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When cutting mask fabric, the operating platform 2 fixedly connected to the top of the base plate 1 provides a stable platform for the overall operation. After the motor 17 starts, it drives the roller shaft 18 and the rotating wheel 19 on the surface to rotate through the second transmission rod. The rotating wheel 19 cooperates with the driven wheel 14 on the surface of the pressure roller 13 to transport the fabric from the feeding end to the cutting area of ​​the operating platform 2. The protective side plate 20 plays a protective and limiting role for the roller shaft 18, ensuring that the fabric conveying process is stable and orderly.

[0034] The second step: When it is necessary to adjust the spacing of the cutters 6 to fit different sizes of masks, start the dual-axis motor 3. Its output end drives the first threaded rod 4 to rotate through the first transmission rod. Since the first threaded rod 4 is threadedly connected to the internal threaded block 5, the internal threaded block 5 will move along the axial direction of the first threaded rod 4, thereby driving the cutters 6 to slide in the groove at the bottom of the movable plate 8, so as to achieve precise adjustment of the spacing between the cutters 6 on both sides. At the same time, the turntable 10 is rotated to drive the second threaded rod 9 to rotate, and the rotating cylinder 11 drives the limiting plate 12 and the pressure roller 13 to move up and down, adjusting the pressure between the pressure roller 13 and the operating table 2 to ensure that the fabric is flat and does not shift during cutting, so as to meet the cutting needs of fabrics of different thicknesses.
