Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting molds for sterile dressing substrates, and in particular to a die-cutting mold for sterile dressing substrates. Background Technology
[0002] As a surgical medical product, sterile dressings are often used to bandage wounds to prevent infection and worsening of injuries, following medical advice. In order to improve production efficiency, sterile dressings are often produced using special die-cutting molds to cut the substrate into the required specifications.
[0003] Common die-cutting dies, when used for die-cutting sterile dressing substrates, employ hydraulic rods to drive the die to close and, during this process, use a flat die to cut the sterile dressing substrate into the shape specified by the die. While common die-cutting dies for sterile dressing substrates generally provide good die-cutting results, some problems still exist:
[0004] 1. When using common sterile dressing substrate punching dies, because the sterile dressing substrate is relatively flexible, the punched and formed sterile dressing substrate is easily adsorbed near the cutting tool due to the extrusion after punching, which affects the feeding of the formed sterile dressing substrate.
[0005] 2. When using common die-cutting dies for sterile dressing substrates, the substrates have good flexibility, and the pressing action of the die during the cutting process can easily cause a certain degree of tensile deformation. Utility Model Content
[0006] The purpose of this invention is to provide a die for cutting sterile dressing substrates, which solves the problem that existing die for cutting sterile dressing substrates does not easily separate the formed sterile dressing substrate from the cutting die after the cutting operation.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a die for cutting a sterile dressing substrate, comprising a support plate and a top die, with guide rods fixedly connected to both sides of the support plate, a top die disposed above the support plate, and a bottom die disposed below the support plate, with linkage auxiliary structures fixedly connected to both sides inside the support plate, the linkage auxiliary structures including a mounting frame, a slide rail, a gear seat, and a drive rack, the mounting frame being fixedly connected to both sides inside the support plate, pressing structures fixedly connected to both sides of the bottom end of the top die, a tool holder mounted at the bottom end of the top die, and a multi-hole suction cup mounted at the top end of the bottom die.
[0008] In use, the support plate is installed at the designated production equipment. Then, the sterile dressing substrate is passed through the middle of the support plate and the top mold. The sterile dressing substrate is moved and stopped by a special traction device. At the same time, a corresponding hydraulic device is installed on the top of the top mold. Driven by the hydraulic device, the top mold is quickly pressed down towards the support plate. During this process, the cutter holder quickly punches the sterile dressing substrate.
[0009] Preferably, the pressing structure includes a first fixed frame, a scissor frame, a second fixed frame, a pressing plate, a sliding rod, a spring, and a sliding sleeve seat. The first fixed frame is fixedly connected to both sides of the bottom of the top mold. A scissor frame is provided below the first fixed frame, and a second fixed frame is provided below the scissor frame. A pressing plate is fixedly connected to the bottom end of the second fixed frame. A sliding rod is fixedly connected to both ends inside the second fixed frame. A spring is sleeved on the outside of the sliding rod. A sliding sleeve seat is hinged to both ends of the scissor frame. Under the elastic force of the spring, the scissor frame continuously presses the pressing plate, and the pressing plate flattens and presses the sterile dressing substrate.
[0010] Preferably, the second fixing frame is in a sliding structure with the sliding sleeve seat via a sliding rod, so that the scissor frame can be quickly unfolded and closed.
[0011] Preferably, the pressing pads are symmetrically distributed about the vertical center line of the top mold, so that the top two sides of the sterile dressing substrate are pressed and supported.
[0012] Preferably, both ends of the mounting bracket are fixedly connected to slide rails, the mounting bracket is rotatably connected to a gear seat, and the slide rails are slidably connected to a drive rack, so that the two sets of drive racks move in opposite directions under the linkage of the gear seat.
[0013] Preferably, the slide rails are symmetrically distributed about the vertical center line of the mounting bracket, thereby enabling the drive rack to move quickly.
[0014] Preferably, the gear seat and the drive rack are meshed, thereby enabling coordinated linkage between the gear seat and the drive rack.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the porous suction cup, in cooperation with the linkage auxiliary structure, makes the porous suction cup adhere tightly to the bottom of the molded sterile dressing substrate, and under the action of air pressure adsorption, the molded sterile dressing substrate is quickly detached. At the same time, during the top die pressing and punching process, the pressing plate continuously presses the two sides of the sterile dressing substrate under the action of spring, so that it maintains good flatness during the punching process.
[0016] 1. Under the meshing structure of the gear seat and the drive rack, the top die moves down while the bottom die moves up in the opposite direction at the same speed, and finally drives the porous suction cup to contact the bottom of the tool seat. At this time, the activated porous suction cup will generate a strong suction negative pressure and adsorb the sterile dressing substrate that has been punched and formed, so that it can be quickly separated and unloaded.
[0017] 2. When the top mold moves down, the first fixed frame and the sliding sleeve seat inside the scissor frame slide quickly along the slide rod through the scissor frame, thereby compressing the spring, which in turn causes the pressing plate to press and smooth the sterile dressing substrate that has passed through the bottom.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] Please see Figures 1-5This utility model provides a die for cutting sterile dressing substrate, including a support plate 1 and a top mold 3. Guide rods 2 are fixedly connected to both ends of the support plate 1. The top mold 3 is provided above the support plate 1, and a bottom mold 5 is provided below the support plate 1. A cutter holder 7 is installed at the bottom end of the top mold 3, and a perforated suction cup 8 is installed at the top end of the bottom mold 5. A linkage auxiliary structure 6 is fixedly connected to both sides inside the support plate 1. The linkage auxiliary structure 6 includes a mounting frame 601, a slide rail 602, a gear seat 603, and a drive rack 604. The mounting frame 601 is fixedly connected to both sides inside the support plate 1. The slide rail 602 is fixedly connected to both ends inside the mounting frame 601. The gear seat 603 is rotatably connected inside the mounting frame 601, and the drive rack 604 is slidably connected inside the slide rail 602. The slide rail 602 is symmetrically distributed about the vertical center line of the mounting frame 601, and the gear seat 603 and the drive rack 604 are meshed.
[0026] See attached document Figure 1 , Figure 3 and Figure 4 During the blanking operation of the sterile dressing substrate blanking die, the top die 3 is rapidly moved towards the support plate 1 under the drive of the hydraulic equipment, thereby causing the cutter holder 7 to blank the sterile dressing substrate. During this process, due to the strong adsorption and flexibility of the sterile dressing substrate, the blanked sterile dressing substrate easily adheres to the surface of the cutter holder 7, resulting in the inability to effectively unload the substrate. Therefore, mounting brackets 601 are fixed on both sides inside the support plate 1. During the downward movement of the top die 3, a set of driving... The rack 604 is driven to move downwards, and at the same time, the movement of one set of drive racks 604 will drive the gear seat 603 to rotate, which in turn drives the other set of drive racks 604 to move upwards in the opposite direction. Since the two sets of drive racks 604 are fixed to the top mold 3 and the bottom mold 5 respectively, the bottom mold 5 will move upwards in the opposite direction at the same speed as the top mold 3 moves downwards, and finally drive the porous suction cup 8 to contact the bottom of the tool holder 7. At this time, the activated porous suction cup 8 will generate a strong suction negative pressure and adsorb the sterile dressing substrate that has been punched and shaped, so that it can be quickly separated and unloaded.
[0027] A pressing structure 4 is fixedly connected to both sides of the bottom end of the top mold 3. The pressing structure 4 includes a first fixed frame 401, a scissor frame 402, a second fixed frame 403, a pressing piece 404, a sliding rod 405, a spring 406, and a sliding sleeve seat 407. The first fixed frame 401 is fixedly connected to both sides of the bottom of the top mold 3. A scissor frame 402 is provided below the first fixed frame 401. A second fixed frame 403 is provided below the scissor frame 402. A pressing piece 404 is fixedly connected to the bottom end of the second fixed frame 403. A sliding rod 405 is fixedly connected to both ends inside the second fixed frame 403. A spring 406 is sleeved on the outside of the sliding rod 405. A sliding sleeve seat 407 is hinged to both ends of the scissor frame 402. The second fixed frame 403 slides with the sliding sleeve seat 407 through the sliding rod 405. The pressing piece 404 is symmetrically distributed about the vertical center line of the top mold 3.
[0028] See attached document Figure 1 and Figure 5 In the process of punching sterile dressing substrate, in order to avoid wrinkles or unevenness in the sterile dressing substrate, which would prevent the sterile dressing substrate from being formed after punching, a first fixing frame 401 is fixed on both sides of the bottom of the top mold 3. When the top mold 3 moves down, the first fixing frame 401 and the sliding sleeve seat 407 inside the scissor frame 402 slide quickly along the slide rod 405 through the scissor frame 402, thereby compressing the spring 406. As the top mold 3 gradually moves down, the spring 406 will also gradually compress and deform, increasing its elasticity, thereby causing the pressing plate 404 to press the sterile dressing substrate that has passed through the bottom, so that the sterile dressing substrate maintains good flatness when being punched.
[0029] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
