Description

Technical Field

[0001] This utility model relates to the field of positioning and guiding technology, specifically to a dialysis paper cutting positioning and guiding device. Background Technology

[0002] As a core material for medical sterilization packaging, dialysis paper requires precise slitting quality to ensure the sealing and sterilization effect of subsequent sealing. Its slitting accuracy is directly related to the safety of medical device packaging.

[0003] In existing dialysis paper slitting processes, tension control is the core element determining slitting quality, and the tension stability of the cutting area is particularly critical. Current slitting devices employ global tension adjustment methods, such as using tension rollers, floating rollers, or roll diameter calculations to achieve overall paper web tension control. However, it is difficult to compensate for tension in the localized cutting area below the cutter. During slitting, fluctuations in paper web transport, changes in roll diameter, or uneven material properties can easily lead to insufficient local tension in the cutting area, resulting in burrs, adhesion, or even incomplete cutting.

[0018] 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.

[0019] Please see Figure 1-4The present invention provides a dialysis paper cutting and positioning guide device, comprising: a cutting table 1, and a guide frame 2 installed on the top outer wall of the cutting table 1. An electric push rod 3 is installed in the middle of the top inner wall of the guide frame 2, and a lifting assembly 4 is slidably connected to the outer wall of the guide frame 2. The bottom of the piston rod of the electric push rod 3 is connected to the lifting assembly 4, and a rolling assembly 5 is rotatably connected to each of the four ends of the lifting assembly 4. A flattening assembly 6 is rotatably connected between two oppositely arranged rolling assemblies 5, and positioning plates 7 are installed at both ends of the top outer wall of the cutting table 1.

[0020] It should be noted that: the paper to be cut is placed on the table of the cutting table 1, and the cutter 9 is installed at the bottom of the lifting assembly 4 to complete the assembly of the material and the cutter before cutting; the positioning plates 7 at both ends of the top outer wall of the cutting table 1 can fit with the two sides of the paper to play a lateral positioning role, so as to prevent the paper from shifting laterally during the cutting process and ensure the cutting position is accurate.

[0021] When the electric push rod 3 is activated, the piston rod of the electric push rod 3 extends downward, driving the lifting assembly 4 connected to it to slide downward along the outer wall of the guide frame 2. The guide frame 2 provides a fixed trajectory for the lifting movement of the lifting assembly 4 through sliding cooperation with the lifting assembly 4, preventing the lifting assembly 4 from shaking or deviating during the descent, and ensuring that the cutter 9 at the bottom of the lifting assembly 4 can be stably aligned with the paper cutting position.

[0022] When the lifting assembly 4 moves downward, its four ends will synchronously push the rolling assembly 5 connected to it, so that the rolling assemblies 5 on both sides of the lifting assembly 4 will roll away from the lifting assembly 4. During the rolling process, the two oppositely arranged rolling assemblies 5 will drive the flattening assembly 6 connected to them to move synchronously - it moves laterally with the movement of the rolling assembly 5, and also rotates in the opposite direction under the drive of the rolling assembly 5. The reverse rotation of the flattening assembly 6 will generate friction with the paper surface, pushing the two sides of the paper below the lifting assembly 4 towards the two ends of the slitting table 1, so that the slitting area of ​​the paper directly below the cutter 9 is tightened, avoiding problems such as rough edges and sticking when the cutter 9 cuts the paper due to insufficient paper tension, and ensuring a crisp and clean cutting effect.

[0023] In a preferred embodiment, the lifting assembly 4 includes a lifting plate 401, guide openings 402 formed at both ends of the top outer wall of the lifting plate 401, and traction rods 403 rotatably mounted at both ends of the outer walls on both sides of the lifting plate 401.

[0024] It should be noted that the traction rods 403, which are rotatably installed at both ends of the outer walls on both sides of the lifting plate 401, are rotatably connected at one end to the rolling assembly 5. When the lifting plate 401 is lowered by the electric push rod 3, the traction rods 403 will push the rolling assembly 5 to roll away from the lifting plate 401.

[0025] In a preferred embodiment, the rolling assembly 5 includes a mounting frame 501, a roller 502 rotatably mounted on the inner wall of the mounting frame 501, and a drive gear 503 mounted on one end of the roller 502, and the bottom end of the traction rod 403 is rotatably connected to the top of the corresponding mounting frame 501.

[0026] It should be noted that the traction rod 403 will push the mounting bracket 501 to move, which in turn will drive the roller 502 to roll, which in turn will drive the drive gear 503 at one end of the roller 502 to rotate.

[0027] In a preferred embodiment, guide rails 8 are installed at the four corners of the top outer wall of the slitting table 1.

[0028] It should be noted that the guide rail 8 can guide the roller 502 and reduce friction.

[0029] In a preferred embodiment, the leveling assembly 6 includes a hollow roller 601, driven gears 602 mounted at both ends of the hollow roller 601, a hexagonal prism 603 mounted on the inner wall of one side of the hollow roller 601, a plurality of push blocks 604 movably inserted into the outer wall of the hollow roller 601 at equal intervals, and a plurality of elastic rods 605 disposed on the outer wall of the side opposite to the push blocks 604 and the hexagonal prism 603 at equal intervals.

[0030] It should be noted here that: the rotation of the driving gear 503 drives the driven gear 602 to rotate in the opposite direction, which in turn drives the hollow roller 601 to rotate;

[0031] The push block 604, which is movably inserted into the outer wall of the hollow roller 601, has an arc-shaped structure at one end, and its outer surface can contact the paper surface. The elastic rod 605 between the push block 604 and the hexagonal prism 603 will apply continuous elastic pressure to the push block 604, so that the push block 604 is tightly attached to the paper surface. When the hollow roller 601 rotates in the opposite direction and moves laterally with the rolling assembly 5, the push block 604 will push the two sides of the paper towards both ends of the slitting table 1 under the compound action of "rotation + movement", and finally tighten the paper below the cutter 9 to ensure the slitting quality.

[0032] In a preferred embodiment, the elastic rod 605 includes a fixed tube 605-1, a movable rod 605-2 slidably connected to the inner wall of the fixed tube 605-1, and a spring 605-3 disposed inside the fixed tube 605-1.

[0033] It should be noted that when the push block 604 contacts the paper and is subjected to the reaction force of the paper, the movable rod 605-2 will retract into the fixed tube 605-1, compressing the spring 605-3. After being compressed, the spring 605-3 will generate a reverse elastic force, which is transmitted to the push block 604 through the movable rod 605-2, so that the push block 604 always maintains close contact with the paper, ensuring that the leveling component 6 has a stable leveling effect on the paper, while avoiding rigid contact that could cause indentations or damage to the paper surface.

[0034] Working principle: The dialysis paper to be cut is placed on the table of the cutting table 1, and the cutter 9 is installed at the bottom of the lifting component 4 to complete the assembly of the material and the cutter before cutting; the positioning plates 7 at both ends of the top outer wall of the cutting table 1 are attached to the two sides of the paper to play a lateral positioning role, so as to prevent the paper from shifting laterally during the cutting process and ensure accurate cutting position.

[0035] The electric push rod 3 installed in the middle of the inner wall of the top of the guide frame 2 is activated. The piston rod of the electric push rod 3 extends downward, driving the lifting assembly 4 connected to it to slide down along the outer wall of the guide frame 2. The guide frame 2 provides a fixed trajectory for the lifting movement of the lifting assembly 4 through sliding cooperation with the lifting assembly 4, preventing the lifting assembly 4 from shaking or deviating when it descends, and ensuring that the cutter 9 at the bottom of the lifting assembly 4 is stably aligned with the paper cutting area.

[0036] When the lifting plate 401 inside the lifting assembly 4 descends under the drive of the electric push rod 3, the traction rods 403 rotatably mounted on both ends of its outer walls move synchronously—the traction rods 403 rotate around their connection point with the lifting plate 401, and at the same time apply a thrust to the mounting frame 501 of the rolling assembly 5; under the action of the thrust, the mounting frame 501 drives the rollers 502 rotatably mounted on the inner wall to move, and the rollers 502 roll along the guide rail 8, so that the rolling assemblies 5 on both sides of the lifting assembly 4 move smoothly away from the lifting assembly 4; at the same time, the drive gear 503 mounted on one end of the roller 502 rotates synchronously with the roller 502 as it rolls.

[0037] The driving gear 503 of the rolling assembly 5 meshes with the driven gear 602 of the flattening assembly 6. When the driving gear 503 rotates, it drives the driven gear 602 to rotate in the opposite direction, thereby driving the hollow roller 601 to rotate synchronously in the opposite direction. The hexagonal prism 603 installed on one side of the inner wall of the hollow roller 601 provides fixed support for multiple elastic rods 605. One end of the fixing tube 605-1 of the elastic rod 605 is connected to the hexagonal prism 603, and the other end is connected to the outer wall of the hollow roller 601 through the movable rod 605-2. The movable push block 604 is connected; the push block 604 is tightly attached to the paper surface under the action of the elastic rod 605. When the push block 604 contacts the paper and is subjected to a reaction force, the movable rod 605-2 retracts into the fixed tube 605-1, compressing the spring 605-3 inside the fixed tube 605-1. The reverse elastic force generated by the spring 605-3 is transmitted to the push block 604 through the movable rod 605-2, ensuring that the push block 604 is always attached to the paper surface.

[0038] While the hollow roller 601 of the flattening component 6 rotates in the opposite direction, it moves laterally along with the rolling component 5. Under the combined action of "rotation + lateral movement", the pushing block 604 pushes the two sides of the paper below the lifting component 4 towards both ends of the slitting table 1, so that the slitting area of ​​the paper directly below the cutter 9 is tightened. After the paper tension stabilizes, the lifting component 4 continues to descend, driving the cutter 9 to contact and cut the paper, avoiding problems such as rough edges and adhesion caused by insufficient paper tension, and ensuring a crisp and clean cutting effect.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
