Description

Technical Field

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

[0002] During the production and processing of medical masks (such as disposable flat masks), after processes such as ear loop welding and folding, irregular edges or fabric wrinkles caused by welding are usually left on the left and right sides. These edges not only affect the overall appearance of the mask, but may also cause discomfort during wear and even affect the product's sealing performance. Therefore, in subsequent processing, the left and right sides are mainly trimmed to remove the irregular edges left after welding the ear loops, in order to improve the aesthetics and wearing comfort of the finished product.

[0003] However, when dealing with such edges, operators usually need to place the welded and folded masks one by one on the conveyor belt. After the equipment completes the edge cutting operation, the finished products are then taken out manually. The entire edge cutting process relies on manual operation, which not only increases labor intensity but also slows down the operation of the production line. On the other hand, operators are prone to fatigue during frequent repetitive operations, which leads to unstable mask placement and affects the edge cutting accuracy and finished product quality.

[0004] Therefore, it is necessary to design an edge-cutting device for medical mask processing. Utility Model Content

[0005] In order to overcome the shortcomings of existing edge-cutting operations that rely on manual loading and unloading, which affects the overall production rhythm, this utility model provides an edge-cutting device for medical mask processing.

An elastic element 11 is connected between the extrusion plate 10 and the blade holder 7. The initial horizontal height of the extrusion plate 10 is lower than the height of the cutters 8 on both sides. The controller 2 is electrically connected to the motor 5 and the first electric push rod 9.

[0021] like Figure 1 and Figure 4 As shown, it also includes a disinfectant storage tank 12 and a spray nozzle 13. The disinfectant storage tank 12 is installed on the upper side of the middle part of the frame 1. The disinfectant storage tank 12 is located on the right side of the mounting frame 6. Multiple spray nozzles 13 are connected and communicated at the lower part of the disinfectant storage tank 12.

[0022] like Figure 1 , Figure 4 and 5As shown, it also includes a blower 14, a baffle 15, and a waste collection frame 16. The blower 14 is installed on the rear right side of the frame 1. The blower 14 is electrically connected to the controller 2. The blower 14 is located on the rear side of the partition plate 4. The baffle 15 is provided on the front right side of the frame 1. The baffle 15 is "T" shaped, and the blower 14 is horizontally aligned with the baffle 15. The waste collection frame 16 is installed on the front right side of the frame 1. The waste collection frame 16 is located in front of the baffle 15.

[0023] like Figure 1 and Figure 4 As shown, it also includes a push block 17, an infrared detector 18, a second electric push rod 19, and a feeding plate 20. The push block 17 is slidably provided on the rear right side of the frame 1. The push block 17 is located behind the partition plate 4. The infrared detector 18 is installed on the right side of the frame 1. The second electric push rod 19 is installed on the rear right side of the frame 1. The telescopic end of the second electric push rod 19 is connected to the push block 17. The infrared detector 18 and the second electric push rod 19 are both electrically connected to the controller 2. The feeding plate 20 is fixedly connected to the front right side of the frame 1. The feeding plate 20 is located directly in front of the push block 17.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes foot pads 101. Multiple foot pads 101 are provided on the lower part of the frame 1 to improve the stability and anti-slip performance of the equipment during operation and ensure operational safety.

[0025] In actual use, the user places the masks requiring edge trimming one by one onto the conveyor belt 3, positioned between two adjacent partition plates 4. The partition plates 4 separate and position the masks, ensuring consistent spacing and position for each mask during transport and preventing deviations from affecting subsequent processing. Then, the controller 2 controls the motor 5 to drive the conveyor belt 3, sequentially transporting the masks to the edge trimming station. When the mask reaches the trimming area, the controller 2 activates the first electric push rod 9, pushing the cutter holder 7 downwards along the guide column. Simultaneously, the cutters 8 on both sides of the cutter holder 7 press down, precisely trimming the left and right edges of the mask, removing irregular corners or fabric wrinkles generated during previous processing, thereby improving the mask's appearance consistency and wearing comfort.

[0026] Before the cutting process begins, the extrusion plate 10 in the middle of the blade holder 7, under the action of the elastic element 11, first contacts the surface of the mask, serving to position and compress it, preventing the mask from shifting or deforming during the cutting process, thereby improving cutting accuracy and finished product quality. The extrusion plate 10 is made of soft plastic material, which can avoid damaging the mask surface. After the cutting is completed, the mask continues to be conveyed forward by the conveyor belt 3 and enters the disinfection area. This area is equipped with a disinfectant storage tank 12, below which is a spray nozzle 13. When the mask passes through, the spray nozzle 13 sprays a small amount of medical-grade disinfectant to disinfect the mask surface online, further improving the hygiene standards and safety of the mask.

[0027] Subsequently, the mask enters the cleaning area. At this time, the blower 14 is activated, blowing air towards the back of the mask to blow the scraps and debris generated during the cutting process forward. Since the cutting process mainly affects the left and right sides of the mask, the scraps are mostly attached to the edges of the mask. Under the action of the blower, they can be easily detached from the mask body. The baffle 15 is set in a "T" shape in front of the cleaning area to prevent the mask body from moving with the wind, while guiding the scraps and debris into the waste collection box 16 at the front. This structural design effectively avoids the accumulation of waste inside the equipment, ensuring the stability and cleanliness of the equipment operation.

[0028] Finally, the mask enters the unloading area. The infrared detector 18 detects in real time whether the mask has reached the unloading position. When the mask is detected to be in place, the controller 2 controls the second electric push rod 19 to move, pushing the push block 20 forward, pushing the mask out from between the partition plates 4, and sliding down the unloading plate 21 into the collection container, completing the automatic unloading and finished product collection. The entire workflow reduces manual intervention and improves production efficiency and product consistency.

[0029] It is worth noting that the conveyor belt 3 needs to be stopped during edge cutting and material discharge. The relevant coordination can be achieved through basic electrical control. Those skilled in the art can also directly understand the relevant operation through this technical solution to achieve the technical effect to be achieved.
