Description

Technical Field

[0001] This utility model relates to the field of nose bridge strip processing technology, specifically a cutting device for injection molding processing of all-plastic nose bridge strips for face masks. Background Technology

[0002] A face mask is a hygiene and epidemic prevention product, generally worn over the mouth and nose to filter the air entering the mouth and nose in order to block viruses and other substances. The nose bridge strip is an important component of the mask. Its function is to position the mask between the two sides of the nose to prevent unfiltered air from being directly inhaled into the body and causing viral infection.

[0003] Existing nose bridge strip segmentation cutting devices for face masks lack the function of flattening and guiding the nose bridge strips during automatic conveying and cutting. Because the nose bridge strip material is relatively soft, it bends and deforms during conveying, and multiple nose bridge strips cannot be stably transported in a straight line before and after cutting, affecting the cutting quality and accuracy. Therefore, we propose a cutting device for injection molding of all-plastic nose bridge strips for face masks. Utility Model Content

[0004] To address the shortcomings of existing devices that lack the function of flattening and guiding nose bridge strips, and the inadequacy of stable linear transport of multiple nose bridge strips before and after cutting, which affects the cutting quality and accuracy of nose bridge strips, this utility model provides a cutting device for injection molding of all-plastic nose bridge strips for face masks. It has the advantages of ensuring stable transport of the cut nose bridge strips and realizing batch cutting of nose bridge strips, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A cutting device for injection molding of all-plastic nose bridge strips for face masks includes a processing table, with conveyor belts rotatably connected to both ends of the processing table, and a support seat connected to the processing table between the two conveyor belts. Multiple annular limiting plates are equidistantly connected to the surface of the conveyor belts, forming a channel between adjacent annular limiting plates. A cutting mechanism connected to the processing table is arranged directly above the support seat. Second brackets are symmetrically arranged on both sides of the cutting mechanism, and mounting seats are raised and lowered at both ends of the second brackets. A second connecting roller is rotatably connected between the two mounting seats through a rotating shaft, and one end of the rotating shaft is coaxially connected to a second motor. Multiple second limiting grooves are equidistantly opened on the outer wall of the second connecting roller and are coaxially arranged therewith. The number of second limiting grooves and channels are equal and their positions correspond.

[0006] Optionally, the second bracket has symmetrically opened mounting cavities on both sides, and vertical rods that penetrate the mounting base are vertically connected inside the mounting cavities. Reset springs coaxial with the vertical rods are symmetrically connected on both sides of the mounting base. The end of the reset spring at the bottom layer is fastened to the inner wall of the mounting cavity. A top plate is slidably connected to the vertical rod. The end of the reset spring at the top layer is fastened to the top plate. The top plate is connected to the second bracket through an adjustment mechanism.

[0007] Optionally, the adjustment mechanism includes an adjustment screw, which is rotatably connected to the top of the top plate and passes through and is threadedly connected to the second bracket.

[0008] Optionally, a handle is coaxially connected to the top of the adjusting screw.

[0009] Optionally, the cutting mechanism includes a first bracket fastened to the top of the support base, a first connecting roller rotatably connected inside the first bracket, and a third motor coaxially connected to one end of the first connecting roller; a cutting blade is axially connected to the outer surface of the first connecting roller, and a plurality of first limiting grooves coaxially arranged with it are equidistantly connected to the outside of the first connecting roller, the number of first limiting grooves being equal to the number of second limiting grooves.

[0010] Optionally, multiple openings are equidistantly made at one end of the support seat near the conveyor belt, with the end of the annular limiting plate located within the openings.

[0011] Optionally, multiple rotating rollers are connected inside the processing table via connecting shafts, and conveyor belts are connected to the outside of the rotating rollers. Pulleys are connected to the connecting shafts at one end of the two conveyor belts, and the two pulleys are connected to each other via belts. A first motor is fixedly connected to one of the connecting shafts.

[0012] Compared with the prior art, this utility model can realize the linear transportation of nose bridge strips through the limiting action of the second limiting groove and the first limiting groove. At the same time, the rotating cutting blade can quickly cut the nose bridge strip. After cutting, the nose bridge strip can be stably transported under the limiting action of the annular limiting plate. This utility model not only realizes the batch cutting and processing of nose bridge strips, but also greatly improves the practicality of the device and brings great convenience to production and processing.

[0021] Reference Figures 1 to 5 This utility model provides a technical solution: a cutting device for injection molding of all-plastic nose bridge strips for face masks, including a processing table 15, with conveyor belts 16 rotatably connected to both ends of the processing table 15. Multiple rotating rollers 17 are connected inside the processing table 15 via connecting shafts 5, and the conveyor belts 16 are connected to the outside of the rotating rollers 17. Figure 1 , 2 As shown, pulleys 4 are connected to the connecting shafts 5 at one end of the two conveyor belts 16. The two pulleys 4 are connected by a belt, and a first motor 1 is fixedly connected to one of the connecting shafts 5. Driven by the first motor 1, the two conveyor belts 16 can rotate and transport.

[0022] like Figure 2As shown, a support base 12 connected to a processing table 15 is provided between two conveyor belts 16. Multiple annular limiting plates 13 are equidistantly connected to the surface of the conveyor belts 16. A channel for placing nose bridge strips is formed between adjacent annular limiting plates 13. Multiple openings 11 are equidistantly opened at one end of the support base 12 near the conveyor belt 16. The ends of the annular limiting plates 13 are located in the openings 11, so that the nose bridge strips can be stably moved from the top of the conveyor belt 16 to the top of the support base 12. In actual use, the nose bridge strips are placed in adjacent channels in sequence, thereby realizing the synchronous transportation and cutting of multiple nose bridge strips, which improves the processing efficiency.

[0023] like Figure 1 , 3 As shown, a cutting mechanism connected to a processing table 15 is provided directly above the support base 12. The cutting mechanism includes a first bracket 7 fastened to the top of the support base 12, a first connecting roller 8 rotatably connected inside the first bracket 7, and a third motor 3 coaxially connected to one end of the first connecting roller 8. A cutting blade 19 is axially connected to the outer surface of the first connecting roller 8, and multiple first limiting grooves 9 coaxially connected to the outside of the first connecting roller 8 at equal intervals. The nose bridge strip is transported to the first connecting roller 8 through the channel, and under the guidance of the first limiting grooves 9, the nose bridge strip can be stably transported and cut, which not only ensures the cutting quality of the nose bridge strip, but also improves the production efficiency of the nose bridge strip.

[0024] like Figure 1 , 4 As shown in Figure 5, second brackets 10 are symmetrically arranged on both sides of the cutting mechanism, and mounting seats 18 are raised and lowered at both ends of the second brackets 10. The two mounting seats 18 are rotatably connected to the second connecting roller 21 through a rotating shaft. One end of the rotating shaft is coaxially connected to the second motor 2. Mounting cavities 14 are symmetrically opened on both sides of the second brackets 10. Vertical rods 23 that penetrate the mounting seats 18 are vertically connected in the mounting cavities 14. Return springs 20 coaxial with the vertical rods 23 are symmetrically connected on both sides of the mounting seats 18. The end of the return spring 20 at the bottom layer is fastened to the inner wall of the mounting cavity 14. A top plate 24 is slidably connected to the vertical rod 23. The end of the return spring 20 at the top layer is fastened to the top plate 24. The top plate 24 is connected to the second bracket 10 through an adjustment mechanism. Under the guidance of the second connecting roller 21, the nose bridge strip can be further ensured to move linearly, thereby ensuring that the nose bridge strip is cut accurately.

[0025] In summary, when using the cutting device for injection molding of the all-plastic nose bridge strip of the mask, the adjustment mechanism includes an adjustment screw 6, which is rotatably connected to the top of the top plate 24. The adjustment screw 6 is also threaded through the second bracket 10. In actual use, a handle is coaxially connected to the top of the adjustment screw 6, and multiple second limiting grooves 22 are equidistantly opened on the outer wall of the second connecting roller 21 and are coaxially arranged therewith. The number of second limiting grooves 22 and channels is equal and their positions correspond, and the number of first limiting grooves 9 is equal to that of second limiting grooves 22.

[0026] like Figure 1 , 3 As shown in Figure 4, under the clamping and limiting action of the second limiting groove 22, the nose bridge strip can be stably transported. After being limited by the second limiting groove 22 on one side, the nose bridge strip can be stably transported to the first connecting roller 8. Under the limiting action of the first limiting groove 9 and the limiting action of the annular limiting plate 13, the nose bridge strip can be transported in a straight line. At the same time, under the action of the rotating cutting blade 19, the nose bridge strip is quickly cut. After being cut, the nose bridge strip can be stably transported under the limiting action of the annular limiting plate 13. At the same time, batch cutting of nose bridge strips is also realized, which greatly improves the practicality of the device.
