Abstract
Description
Technical Field
[0001] This utility model relates to the field of material strip cutting technology, specifically to a PAD bandage fixed-length cutting machine. Background Technology
[0002] PAD bandages typically refer to bandages with padding (PAD). These bandages generally have a multi-layered structure. The outermost layer is the wrapping layer, usually made of materials such as gauze and elastic fibers, used for fixation and providing pressure. The padding layer (PAD) is located inside and can be made of soft materials such as cotton, non-woven fabric, and foam. Using appropriate tooling, the bandages are assembled and packaged. For example, some medical PAD bandages have bubble wrap as the padding, which forms part of the varicose vein medication kit. The function of this pad is to concentrate the compression force on the treated vein, minimizing the possibility of residual blood clots.
[0003] Bandages are typically manufactured in rolls, which facilitates large-scale continuous production, and the roll shape takes up relatively little space for storage. In actual use, the required length of the bandage varies depending on the bandaging site, bandaging method, wound size, and dressing application. Therefore, roll bandages need to be cut to a fixed length to meet the needs of different usage scenarios. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a PAD bandage fixed-length cutting machine. After the material pulling mechanism pulls the material strip to a certain length, it is cut by the cutting pliers. During the material pulling process, the material feeding mechanism moves left and right to change the feeding direction, which can realize the folding and collection of the material in the material frame.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A PAD bandage fixed-length cutting machine includes a base, on which a frame is mounted. A feeding mechanism for feeding material strips is located at the top of the frame. A pulling mechanism for pulling material strips to a fixed length is located on the front side of the frame. Below the pulling mechanism is a cutting clamp for cutting the material strip. Below the cutting clamp is a material frame that moves horizontally along the X-axis. A material-pushing mechanism that moves horizontally along the Y-axis is located between the material frame and the cutting clamp. One end of the material strip is wound around the feeding mechanism, and the other end passes sequentially through the output ends of the pulling mechanism, the cutting clamp, and the material-pushing mechanism before falling into the material frame.
[0007] Optionally, the material pulling mechanism includes a drive motor installed inside the frame, the output end of the drive motor extending to the front side of the frame and equipped with a drive wheel, a driven wheel rotatably mounted on one side of the drive wheel, the material strip passing between the outer circumferential surfaces of the drive wheel and the driven wheel, and an encoder connected to one end of the driven wheel, the encoder being located inside the frame.
[0008] Optionally, the feeding mechanism includes a Y-axis linear module installed inside the frame. The output end of the Y-axis linear module is connected to a support plate, and two levers parallel to the X-axis direction are fixedly installed on the support plate. A guide groove parallel to the Y-axis direction is opened on the front side of the frame. The levers extend through the guide groove to the front side of the frame, and the material strip passes between the two levers.
[0009] Optionally, the feeding mechanism includes a bracket fixedly installed on the top of the frame, a feeding motor installed on the rear side of the bracket, a material tray installed at the output end of the feeding motor, one end of the material strip being wound on the material tray, and the material tray being located on the front side of the bracket.
[0010] Optionally, a guide roller assembly is installed above the material pulling mechanism, and a support roller assembly is installed on the side of the guide roller assembly near the material feeding mechanism. One end of the material strip passes through the material pulling mechanism from above, successively around the support roller assembly and the guide roller assembly.
[0011] Optionally, a sensing component for detecting the position of the material strip is also provided on the front side of the frame, and the sensing component is located diagonally below the support roller assembly.
[0012] Optionally, the base is equipped with an X-axis linear module and a slide rail parallel to the X-axis direction. Both are located at the bottom of the material frame, and the material frame is fixedly connected to the output end of the X-axis linear module and slidably connected to the slide rail.
[0013] Optionally, a clearance hole is provided on the front side of the frame, and the material frame extends through the clearance hole to the inside of the frame.
[0014] Optionally, a protective frame is also fixedly installed on the upper part of the frame. The protective frame has a U-shaped structure, and the support roller assembly, the guide roller assembly, and the sensing assembly are all located inside the protective frame.
[0015] Optionally, two feeding mechanisms are provided, symmetrically distributed on the top of the frame.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] (1) In this utility model, after the feeding mechanism finishes feeding the material strip, the pulling mechanism pulls it to a specified length. During the pulling process, the material feeding mechanism moves left and right along the Y-axis to change the feeding direction, thereby realizing the folding and collection of the material in the material frame. Then, the material strip is cut by the cutting pliers to complete the fixed-length cutting. The structure of this device is simple and the design is ingenious. It can not only complete the fixed-length cutting of the material strip, but also realize the folding and collection of the material in the material frame. It is easy to operate and has high work efficiency.
[0018] (2) During the above material pulling process, the motor drives the drive wheel to rotate, and the drive wheel then drives the driven wheel to rotate, so that the material belt located between the two can be continuously and stably conveyed downwards. The driven wheel drives the encoder to work, and the length of the material belt can be accurately calculated by the rotation of the encoder.
[0019] (3) When the sensing component does not detect the material belt, the feeding motor starts feeding the material until the sensing component detects the material and the feeding motor stops feeding the material. This design can avoid the material belt length being inaccurate due to excessive force during the feeding process. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0027] Example 1
[0028] like Figures 1-4 As shown, a PAD bandage fixed-length cutting machine includes a base 1, a frame 2 fixedly installed on the base 1, a feeding mechanism 4 provided on the top of the frame 2, and a pulling mechanism, a cutting pliers 10, a pushing mechanism and a material frame 3 arranged sequentially from top to bottom on the front side of the frame 2. One end of the material strip is wound around the feeding mechanism 4, and the other end passes through the output ends of the pulling mechanism, the cutting pliers 10 and the pushing mechanism in sequence before falling into the material frame 3.
[0029] Since the uncut bandages are stored in rolls, the function of the feeding mechanism 4 is to output the rolls of bandages in strip form. The pulling mechanism then pulls the released strip to a fixed length so that it can fall into the material frame 3. After the pulling mechanism pulls the specified length, the cutting pliers 10 are activated to cut the strip, completing the fixed-length cutting. During the pulling process, the material feeding mechanism moves left and right along the Y-axis to change the feeding direction, so that the strip can be folded and collected in the material frame 3, making it convenient to retrieve later and avoiding tangling.
[0030] Among them, the cutting pliers 10 is existing technology, with a structure similar to scissors, and is driven by a motor to cut the material strip.
[0031] The material pulling mechanism includes a drive motor installed inside the frame 2. The output end of the drive motor extends to the front of the frame 2 and is equipped with a drive wheel 8. A driven wheel 9 is rotatably installed on one side of the drive wheel 8. The material belt passes between the outer circumferential surfaces of the drive wheel 8 and the driven wheel 9. An encoder 14 is connected to one end of the driven wheel 9. The encoder 14 is located inside the frame 2.
[0032] The drive motor is preferably a servo motor, which can drive the drive wheel 8 to rotate clockwise. The drive wheel 8 then drives the driven wheel 9 to rotate counterclockwise. After the material belt passes through the circumference of the two wheels, it is continuously and stably conveyed downward under the action of extrusion and friction. During this process, the driven wheel 9 drives the encoder 14 to rotate. The length of the material belt that has been pulled can be accurately calculated by the rotation of the encoder 14.
[0033] The feeding mechanism includes a Y-axis linear module 15 installed inside the frame 2. The output end of the Y-axis linear module 15 is connected to a support plate 16. Two levers 11 parallel to the X-axis direction are fixedly installed on the support plate 16. A guide groove 202 parallel to the Y-axis direction is opened on the front side of the frame 2. The levers 11 extend through the guide groove 202 to the front side of the frame 2, and the material strip passes between the two levers 11.
[0034] The Y-axis linear module 15 can drive the support plate 16 to move horizontally along the Y-axis direction. The support plate 16 then drives the lever 11 to move left and right along the guide groove 202. The material strip passes between the two levers 11. During the movement of the lever 11, the feeding direction is changed, thereby realizing the folding and collection of the material in the material frame 3. This can avoid the problem of the material strips getting tangled together. After cutting, the material head can be placed on the edge of the material frame 3 by the material feeding mechanism, which is convenient for the staff to pick up later.
[0035] An X-axis linear module 12 and a slide rail 13 are mounted on the base 1. Both are parallel to the X-axis direction and located at the bottom of the material frame 3. The material frame 3 is fixedly connected to the output end of the X-axis linear module 12 and slidably connected to the slide rail 13.
[0036] The X-axis linear module 12 can drive the material frame 3 to move along the slide rail 13. After the cut material strip is placed into the material frame 3, the material frame 3 moves a certain distance along the X-axis and then the next material strip is placed in. This can avoid the overlap between multiple material strips and make it easier to pick up later.
[0037] The X-axis linear module 12 and the Y-axis linear module 15 both adopt existing technologies, such as electric cylinders, pneumatic cylinders or hydraulic cylinders, with electric cylinders being preferred here.
[0038] Furthermore, a clearance hole 201 is provided on the front side of the frame 2, through which the material frame 3 extends to the inside of the frame 2. In order to avoid the material frame 3 from colliding and interfering with the side of the frame 2 during its movement along the X-axis, and also to facilitate the material frame 3 to better collect the material strip, the clearance hole 201 allows one side of the material frame 3 to enter the interior of the frame 2, ensuring that the movement of the material frame 3 is provided with sufficient space.
[0039] The feeding mechanism 4 includes a bracket 401 fixedly installed on the top of the frame 2. A feeding motor 402 is installed on the rear side of the bracket 401. A material tray 403 is installed at the output end of the feeding motor 402. One end of the material strip is wound on the material tray 403, and the material tray 403 is located on the front side of the bracket 401.
[0040] The feeding motor 402 also adopts a servo motor, which can drive the material tray 403 to rotate, thereby causing the material belt to detach from the material tray 403 to achieve feeding; after feeding, the material belt is pulled into the material frame 3 by the traction of the driving wheel 8 and the driven wheel 9.
[0041] There are two feeding mechanisms 4, symmetrically distributed on the top of the frame 2; one serves as the main feeding mechanism, and the other provides spare material rolls to ensure that the cutting work will not be interrupted due to the replacement of the material tray 403, thereby improving its working efficiency.
[0042] Working principle:
[0043] First, the material strip is manually passed between the drive wheel 8 and the driven wheel 9 of the feeding mechanism. Then, the equipment is started, and the feeding motor 402 drives the material tray 403 to rotate, causing the material strip to detach from the material tray 403 to achieve feeding. The drive motor drives the drive wheel 8 to rotate clockwise, and the drive wheel 8 then drives the driven wheel 9 to rotate counterclockwise. After the material strip passes through the circumference of the two wheels, it is continuously and stably conveyed downward under the action of compression and friction. After reaching the specified length, the material strip is cut by the shearing pliers 10. During the feeding process, the material strip passes between the two levers 11. With the movement of the levers 11, the feeding direction is changed, thereby realizing the folding and collection of the material in the material frame 3.
[0044] Example 2
[0045] like Figure 1 , Figure 4 As shown, based on Embodiment 1, a guide roller assembly 6 is installed above the material pulling mechanism, and a support roller assembly 5 is installed on the side of the guide roller assembly 6 near the material feeding mechanism 4. One end of the material strip passes through the material pulling mechanism after passing over the support roller assembly 5 and the guide roller assembly 6 from above.
[0046] The guide roller assembly 6 and the support roller assembly 5 have the same structure, including a roller body and a limiting plate. The limiting plate is fixedly sleeved on the roller body, and one end of the roller body is fixedly installed on the front side of the frame 2, and the roller body is perpendicular to the front side of the frame 2. The guide roller assembly 6 and the support roller assembly 5 mainly play a supporting and guiding role to ensure that the material strip can be smoothly pulled by the pulling mechanism.
[0047] Furthermore, a sensing component 7 for detecting the position of the material strip is also provided on the front side of the frame 2. The sensing component 7 is located diagonally below the support roller assembly 5.
[0048] If the pulling speed is greater than the releasing speed, the material strip will be taut, and the length detected by the encoder 14 may be inaccurate. Therefore, before pulling the material, a section of the material strip is released first. Due to its own weight and supported by the guide roller assembly 6 and the support roller assembly 5, it can hang freely. When this section of the material strip is pulled, it will not be pulled between it and the material tray 403.
[0049] The sensing component 7 can use an existing infrared position sensor, which can detect whether there is a material strip in the front area. When the sensing component 7 does not detect the material strip, the feeding motor 402 starts feeding the material until the sensing component 7 detects the material. The feeding motor 402 stops feeding the material. This design can avoid the material strip length being inaccurate due to excessive force during the feeding process.
[0050] In addition, a protective frame 17 is fixedly installed on the upper part of the frame 2. The protective frame 17 has a U-shaped structure. The support roller assembly 5, guide roller assembly 6 and sensing assembly 7 are all located inside the protective frame 17. A control panel (touch screen) is also provided on the outside of the protective frame 17. This not only protects the support roller assembly 5, guide roller assembly 6 and sensing assembly 7, but also allows users to set the corresponding parameters through the control panel on the outside.
[0051] In summary, the bandage length cutting machine proposed in this utility model can not only automatically cut bandages to a fixed length, but also fold the cut material strips in an orderly manner and place them in the material frame 3. It has a simple structure, is easy to operate, and greatly saves manpower while improving the work efficiency of length cutting.
