Description

Technical Field

[0001] This utility model belongs to the field of protective clothing processing technology, specifically a punching device for processing protective clothing. Background Technology

[0002] Protective clothing, as the name suggests, is clothing used for protection. Common types include health-type protective clothing, safety-type protective clothing, and hygiene-type work clothes. Protective clothing generally consists of a hood, top, and pants, forming a one-piece structure, but two-piece structures are also available. Its structure is reasonable, easy to wear, and the joints are tight. Elastic bands are often used at the cuffs, ankles, and hood to ensure a seal. Materials range from natural materials such as cotton, wool, silk, and lead, to synthetic materials such as rubber, plastics, resins, and synthetic fibers, as well as modern functional materials and composite materials. During the manufacturing process, protective clothing usually requires perforations. Perforations in appropriate areas increase airflow and improve the wearer's comfort, especially for medical personnel and industrial workers who wear protective clothing for extended periods, effectively reducing stuffiness. Perforations can also be used to install accessories, such as ventilation valves and connecting pipes, to meet specific protective or functional requirements.

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.

[0030] like Figures 1 to 5As shown, this utility model provides a punching device for processing protective clothing, including a base 1, a frame 2 fixed on the top of the base 1, a hole opener pressing component 3 installed on the frame 2, a hole opener changing component 4 provided above the base 1, and a hole opener 5 connected to the hole opener changing component 4.

[0031] The hole punching device changing assembly 4 includes a mounting platform 41 rotatably connected to the frame 2. The mounting platform 41 is provided with multiple evenly distributed reset mechanisms 42. Each reset mechanism 42 is connected to a hole punch 5 with a different hole diameter. The position of the hole punch 5 corresponds vertically to the position of the hole punch pressing assembly 3, and the hole punch pressing assembly 3 drives the corresponding hole punch 5 to move down. The top of the mounting platform 41 is connected to a rotary drive mechanism 43. When it is necessary to change the hole punch 5 to a different size, the corresponding hole punch 5 can be quickly adjusted to the corresponding position for drilling, without the need to disassemble and replace the hole punch 5, thus improving processing efficiency.

[0032] Specifically, the hole opener pressing assembly 3 includes a hydraulic cylinder 31 mounted on the frame 2. The piston rod of the hydraulic cylinder 31 is connected to a pressure head 32, which is movably connected to the corresponding hole opener 5 below it, for applying pressure to press the hole opener 5 onto the protective clothing.

[0033] Furthermore, a guide rod 6 is fixedly connected to the center of the top of the inner cavity of the hole opener 5. A push-out spring 7 is sleeved on the outside of the guide rod 6. The top of the push-out spring 7 is connected to the inner wall of the hole opener 5, and the bottom of the push-out spring 7 is connected to a push-out ring 8. The push-out ring 8 moves up and down inside the hole opener 5. The bottom of the guide rod 6 is located inside the push-out ring 8, pushing the generated waste material downward.

[0034] Furthermore, the reset mechanism 42 includes a mounting cavity 421 opened on the mounting platform 41. A movable block 422 is provided in the mounting cavity 421. A reset spring 423 is connected to the bottom of the movable block 422. A connecting block 424 is fixedly connected to the side of the movable block 422. The connecting block 424 is fixedly connected to the hole opener 5. A limit groove 425 is opened on the mounting platform 41 at the position corresponding to the connecting block 424. The connecting block 424 passes through the limit groove 425. When the hydraulic cylinder 31 retracts, the hole opener 5 can be reset upward.

[0035] It is worth noting that the top of the hole opener 5 is fixedly connected to a corresponding block 9, the top of the corresponding block 9 is provided with a corresponding groove 10, and the bottom of the pressure head 32 is provided with a corresponding protrusion 11 corresponding to the corresponding groove 10, to ensure the stability of the connection.

[0036] It is worth noting that the rotary drive mechanism 43 includes a rotary shaft 431 fixedly connected to the mounting platform 41. A driven gear 432 is fixedly connected to the top of the rotary shaft 431. The driven gear 432 is meshed with a drive gear 433. The drive gear 433 is connected to a drive motor 434 through a motor shaft, which is used to drive the mounting platform 41 to rotate in order to change different hole openers 5.

[0037] It is worth mentioning that a connecting rod 12 is fixedly connected to the bottom center of the mounting platform 41, and a placement platform 13 is fixedly connected to the bottom end of the connecting rod 12. The bottom of the placement platform 13 is rotatably connected to the base 1. A through hole 14 is opened on the placement platform 13 at the position corresponding to the hole punch 5. A guide hole 15 is opened on the base 1 at the position corresponding to the hole punch pressing component 3. A collection drawer 16 is installed on the base 1. The position of the guide hole 15 matches the collection drawer 16, so that the waste generated during drilling is guided into the collection drawer 16 for easy collection.

[0038] Hydraulic cylinder 31 and drive motor 434 are existing technologies and will not be described in detail. In addition, this utility model also includes power supply, controller and switch, which are not the main technical points of this patent and will not be described in detail.

[0039] Working principle and process: Select the appropriate size hole punch 5 according to the requirements, start the drive motor 434 of the rotary drive mechanism 43, which in turn drives the driven gear 432 to rotate, and then the rotating shaft 431 drives the mounting platform 41 to rotate, so that the required hole punch 5 is directly below the hole punch pressing assembly 3. At the same time, the connecting rod 12 drives the placement platform 13 to rotate, so that the through hole 14 matches the hole punch 5 of the corresponding size. Place the punching position of the protective clothing on the placement platform 13, and make the punching position correspond to the position of the corresponding through hole 14. Start the hole punch pressing. The hydraulic cylinder 31 of component 3 extends, and the pressure head 32 moves down to the corresponding block 9, and the corresponding protrusion 11 extends into the corresponding groove 10. Then the corresponding block 9 drives the hole opener 5 to move down, so that the hole opener 5 presses on the punching position of the protective clothing, and a hole can be punched out. At the same time as the waste is generated, under the elastic force of the push spring 7, the push ring 8 will push the waste out of the inside of the hole opener 5. Then the waste falls into the collection drawer 16 through the through hole 14 and the guide hole 15. When the hydraulic cylinder 31 retracts, the hole opener 5 is reset under the action of the reset mechanism 42, and the punching work of the protective clothing can be completed.
