Description

Technical Field

[0001] This utility model relates to the field of nose pad processing technology, and in particular to a nose pad blank cutting machine. Background Technology

[0002] In the eyewear manufacturing industry, nose pads, as a key component that comes into direct contact with the wearer's nose, are crucial in terms of precision, comfort, and appearance. Nose pads are typically made of materials such as silicone and plastic. During production, preforms of specific shapes must be precisely separated from sheet or strip substrates. Therefore, efficient nose pad preform cutting equipment is an indispensable part of automated eyewear accessory production lines, directly impacting production efficiency and product quality. A nose pad preform cutting machine capable of precise, efficient, and automated cutting with reliable collection capabilities is of great significance for improving the level of eyewear manufacturing.

[0003] The nose pad blank cutting machines in the existing technology are mainly divided into two categories in terms of cutting method. One type adopts a rotary cutting structure, in which a cutting blade driven by a motor rotates at high speed to complete the cutting. The other type usually adopts a die-cutting process, in which a die-cutting component equipped with a cutting blade is driven by a motor or hydraulic drive device to perform vertical reciprocating motion to achieve cutting.

[0004] However, when using the existing die-cutting process, the rigid clamping method during the downward pressing and cutting process of the die-cutting component can easily cause the blank to be deformed or slightly displaced, affecting the cutting accuracy. After the cutting is completed, the cut finished product is easily stuck in the cutter or bottom mold cavity and is difficult to reliably remove. This jamming phenomenon can not only cause damage to the finished product or generate scrap, but may also interrupt the continuous operation of the equipment and require frequent manual intervention to clean it. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a nose pad blank cutting machine, which aims to improve the problem that when using the die-cutting process in the prior art, the rigid clamping method easily affects the cutting accuracy, and the cut finished products are easily stuck in the cutter or bottom mold cavity, making it difficult to reliably remove them. This not only causes damage to the finished products or generates scrap, but may also interrupt the continuous operation of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nose pad preform cutting machine, comprising a support, a bracket fixedly connected to the upper surface of the support, guide rails symmetrically arranged on the inner wall of the bracket, a toothed frame slidably connected to the inner wall of the guide rail, a motor fixedly connected to one side of the outer wall of the bracket, a rotating shaft fixedly connected to the output end of the motor, a half gear fixedly connected to the outer wall of the rotating shaft, the tooth end of the half gear meshing with the tooth end of the toothed frame, and a die-cutting assembly arranged on the opposite side of the toothed frame;

[0007] The die-cutting assembly includes a cutter, the outer wall of which is disposed inside the toothed frame. A mold base is fixedly connected to the upper surface of the cutter. A slide tube is fixedly connected inside the mold base. A slide rod is slidably connected to the inner wall of the slide tube. A slider is fixedly connected to one end of the slide rod. The outer wall of the slider is slidably connected to the inner wall of the cutter. A connecting plate is fixedly connected to the upper surface of the mold base. The outer wall of the connecting plate is fixedly connected to the opposite side of the toothed frame.

[0008] Furthermore, a spring is sleeved on the outside of the slide rod, one end of the spring is fixedly connected to the lower surface of the slide tube, and the other end of the spring is fixedly connected to the upper surface of the slider.

[0009] Furthermore, a slide tube is fixedly connected to the inner wall of the mold base, and a slide rod is slidably connected to the inner wall of the slide tube. A pressure plate is fixedly connected to one end of the slide rod.

[0010] Furthermore, a second spring is sleeved on the outside of the second slide rod. One end of the second spring is fixedly connected to the lower surface of the second slide tube, and the other end of the second spring is fixedly connected to the upper surface of the pressure plate.

[0011] Furthermore, a second motor is fixedly connected to one side of the outer wall of the support, and a conveyor belt is provided at the output end of the second motor. A positioning groove is opened on the outer wall of the conveyor belt, and the outer wall of the conveyor belt is set on the inner wall of the support.

[0012] Furthermore, a support plate is fixedly connected to one side of the outer wall of the support, a guide rod is fixedly connected to the upper surface of the support plate, a mounting plate is fixedly connected to one end of the guide rod, a hydraulic rod is fixedly connected to the upper surface of the mounting plate, an inclined block is fixedly connected to the output end of the hydraulic rod, and the inner wall of the inclined block is slidably connected to the outer wall of the guide rod.

[0013] Furthermore, a spring three is sleeved on the outside of the guide rod. One end of the spring three is fixedly connected to the upper surface of the support plate one, and the other end of the spring three is fixedly connected to the lower surface of the inclined block.

[0014] Furthermore, a finished product basket is fixedly connected to the inner wall of the first support plate, a second support plate is fixedly connected to one side of the outer wall of the first support plate, a waste roller and a guide roller are rotatably connected to the inner wall of the second support plate, a third motor is fixedly connected to one side of the outer wall of the second support plate, and a waste roller is fixedly connected to the output end of the third motor.

[0016] 1. In this utility model, the motor drives the half gear to make the tooth frame and the die-cutting assembly move vertically and reciprocally. When moving downward, the pressure plate first contacts the blank, and under the action of the spring, it slides in the slide tube through the slide rod, applying a flexible clamping force to prevent the blank from shifting. After the cutter cuts, the slider is compressed by the spring. After completion, the spring rebounds and pushes out the finished product to prevent it from getting stuck in the cutter.

The finished product is then pushed out by the slider to ensure continuous operation, thereby improving the practicality of the device.

[0017] 2. In this utility model, the hydraulic rod is activated to push the inclined block down along the guide rod. The inclined surface of the inclined block guides the cut nose pads to slide into the finished product basket. At the same time, the motor is activated to drive the waste roller to rotate. With the assistance of the guide roller, the waste is wound onto the waste roller for collection. The finished product is guided into the basket by the inclined surface, and the waste roller automatically winds up the waste, thereby improving the collection efficiency, reducing manual intervention, and thus improving the practicality of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4 This utility model provides an embodiment of a nose pad preform cutting machine, including a support 1. A second motor 19 is fixedly connected to one side of the outer wall of the support 1. A conveyor belt 20 is provided at the output end of the second motor 19. The outer wall of the conveyor belt 20 has a positioning groove 21 for fixing the position of the nose pad preform on the conveyor belt 20. The outer wall of the conveyor belt 20 is set on the inner wall of the support 1. A bracket 2 is fixedly connected to the upper surface of the support 1. The inner wall of the bracket 2 is symmetrically provided with guide rails 3 for limiting the movement trajectory of the toothed frame 4 to ensure that the die-cutting assembly moves vertically without deviation. The inner wall of the guide rails 3 is slidably connected to... A gear frame 4 and a bracket 2 have a motor 6 fixedly connected to one side of their outer wall for providing rotational power. A rotating shaft 7 is fixedly connected to the output end of the motor 6. A half-gear 5 is fixedly connected to the outer wall of the rotating shaft 7, and the tooth ends of the half-gear 5 mesh with the tooth ends of the gear frame 4. A die-cutting assembly is provided on the opposite side of the gear frame 4. The die-cutting assembly includes a cutter 14 for cutting and separating the blank. The outer wall of the cutter 14 is located inside the gear frame 4. A mold base 9 is fixedly connected to the upper surface of the cutter 14. A slide tube 10 is fixedly connected inside the mold base 9. A slide rod 11 is slidably connected to the inner wall of the slide tube 10. One end of the slide rod 11 is fixedly... A slider 13 is fixedly connected to the cut nose bridge piece, directly contacting and pushing it. The outer wall of the slider 13 is slidably connected to the inner wall of the cutter 14. A connecting plate 8 for connecting the toothed frame 4 and the mold base 9 is fixedly connected to the upper surface of the mold base 9. The outer wall of the connecting plate 8 is fixedly connected to the opposite side of the toothed frame 4. A spring 12 is sleeved on the outside of the slide rod 11 for storing elastic force when squeezed by the slider 13 during die cutting, and releasing the elastic force to push the slider 13 downward after die cutting. One end of the spring 12 is fixedly connected to the lower surface of the slide tube 10, and the other end of the spring 12 is fixedly connected to the upper surface of the slider 13. A slide tube 2 15 is fixedly connected to the inner wall of the die holder 9. A slide rod 2 16 is slidably connected to the inner wall of the slide tube 2 15. A pressure plate 18 is fixedly connected to one end of the slide rod 2 16. The pressure plate 18 is made of compressible colloid material. Its function is to first contact the blank when the die-cutting assembly moves downward. Under the action of the spring 2 17, it applies a flexible pressure force to the blank to prevent the blank from shifting or warping. At the same time, the colloid material can avoid damaging the blank. The slide rod 2 16 is fitted with a spring 2 17. One end of the spring 2 17 is fixedly connected to the lower surface of the slide tube 2 15, and the other end of the spring 2 17 is fixedly connected to the upper surface of the pressure plate 18.

[0027] Specifically, the half-gear 5, in conjunction with the gear frame 4, transmits power, converting the rotational motion of motor 6 into the vertical reciprocating motion of gear frame 4. Through the partial meshing characteristics of the half-gear 5, gear frame 4 is alternately subjected to force to achieve reciprocating motion, thus providing power to the die-cutting assembly. The rotating shaft 7, in conjunction with motor 6 and half-gear 5, transmits power, transferring the rotational motion of motor 6 to half-gear 5, causing half-gear 5 to rotate synchronously with the motor, achieving accurate power transmission and ensuring synchronous transmission. The slide rod 11, in conjunction with slider 13 and spring 12, moves. When slider 13 is compressed, it slides upward to compress spring 12; when spring 12 returns to its original position, it pushes slider 13 downward, achieving force transmission to eject the finished product. Spring 17, in conjunction with slide rod 16, elastically extends and retracts. When the pressure plate 18 contacts the blank, it continuously presses down, achieving a stable and adaptive pressure force, preventing damage to the blank from hard impacts.

[0028] Reference Figure 2 and Figure 5 A support plate 22 is fixedly connected to one side of the outer wall of the support 1. A guide rod 23 is fixedly connected to the upper surface of the support plate 22 to guide the inclined block 24 to move vertically, thus limiting the movement direction of the inclined block 24 and achieving the effect of smooth movement of the inclined block 24. One end of the guide rod 23 is fixedly connected to a mounting plate 32 for fixing and installing a hydraulic rod 25. The upper surface of the mounting plate 32 is fixedly connected to the hydraulic rod 25. The output end of the hydraulic rod 25 is fixedly connected to the inclined block 24, whose inclined surface is designed to guide the finished product to slide down. The inner wall of the inclined block 24 is slidably connected to the outer wall of the guide rod 23. A spring is sleeved on the outside of the guide rod 23. 26. One end of spring 3 26 is fixedly connected to the upper surface of support plate 1 22, and the other end of spring 3 26 is fixedly connected to the lower surface of inclined block 24. A finished product basket 27 is fixedly connected to the inner wall of support plate 1 22. A support plate 28 is fixedly connected to one side of the outer wall of support plate 1 22. A waste roller 30 and a guide roller 31 for assisting in guiding the waste generated by cutting into the waste roller 30 are rotatably connected to the inner wall of support plate 28 to prevent the waste from shifting or getting tangled during the conveying process. A motor 3 29 is fixedly connected to one side of the outer wall of support plate 28. The output end of motor 3 29 is fixedly connected to waste roller 30.

[0029] Specifically, the inclined block 24, in conjunction with the hydraulic rod 25 and the guide rod 23, moves up and down. Driven by the hydraulic rod 25, it descends along the guide rod 23, guiding the finished nose pads through its inclined surface to slide into the finished product basket 27, achieving the effect of guiding and collecting the finished products. The finished product basket 27 is used to collect the cut nose pads that slide down the inclined surface of the inclined block 24, realizing the centralized storage of finished products, facilitating subsequent sorting and processing of finished products, and improving production efficiency. The waste roller 30, in conjunction with the motor 29 and the guide roller 31, rotates. Driven by the motor 29, it rotates and winds the waste guided by the guide roller 31 onto its own surface, achieving the effect of centralized waste collection and keeping the working area clean.

[0030] Working principle: When it is necessary to cut and separate the nose pad preform with connecting adhesive, the nose pad preform is first placed in the positioning groove 21 of the conveyor belt 20. The motor 19 is started to transport the preform to the die-cutting station. Then, the motor 6 is started to drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the half gear 5 to rotate, thereby realizing that the half gear 5 drives the gear frame 4 to move vertically back and forth along the guide rail 3, thereby driving the die-cutting assembly to move vertically back and forth. During the downward movement of the die-cutting assembly, the pressure plate 18 first contacts the preform. As the die-cutting assembly continues to move downward, the pressure plate 18, under the action of the spring 17, slides in the slide tube 15 through the slide rod 16, applying a stable and flexible clamping force to the preform to prevent the preform from shifting or warping during cutting. Then, the cutter 14 contacts the preform to complete the cutting of the nose pad preform. At the same time, the slider 13 is subjected to The blank is pressed and slides along the slide bar 11, compressing the spring 12. After die cutting, the spring 12 releases its elasticity, pushing the slider 13 to push the cut nose pad product downward from the inner cavity of the cutter 14, preventing the product from getting stuck in the cutter 14. After the product is pushed out, it is conveyed by the conveyor belt 20 or pushed by the blank behind it to fall onto the inclined block 24. Then, the hydraulic rod 25 is activated to push the inclined block 24 down along the guide rod 23 and compress the spring 26. The inclined surface of the inclined block 24 guides the cut nose pad to slide into the finished product basket 27. At the same time, the motor 29 is activated to drive the waste roller 30 to rotate. The waste is wound onto the waste roller 30 for collection with the assistance of the guide roller 31. By controlling the speed of the motor 6 to synchronize with the intermittent rhythm of the conveyor belt 20, a continuous automated cutting cycle is achieved.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
