Description

Technical Field

[0001] This utility model relates to the field of medical tape technology, and in particular to a slitting device for the production of medical tape. Background Technology

[0002] In the medical field, medical tape is a basic consumable widely used in wound dressing, medical device fixation, catheter bonding, and other scenarios. Its quality directly affects the treatment effect and safety of patients. Therefore, the slitting process in the production of medical tape is crucial. The slitting accuracy, efficiency, and the flatness of the tape edges after slitting all directly determine the quality of the product. A slitting device for medical tape production is a piece of equipment used in the production process of medical tape. Its main function is to slit large rolls of medical tape into smaller rolls or segments that meet specific size requirements.

[0003] Currently, most slitting devices do not secure larger medical tapes during the slitting process. Because medical tapes are soft and elastic, the unsecured tapes are prone to displacement, wrinkling, or twisting under the force generated by the high-speed rotation of the slitting blade. This results in uneven tape widths and jagged edges, failing to meet the strict dimensional standards of medical tapes and directly affecting product quality. Therefore, we propose a slitting device for medical tape production. Utility Model Content

[0004] The purpose of this invention is to provide a slitting device for the production of medical tape, in order to solve the problem that most current slitting devices do not fix larger-sized medical tapes during the slitting process. Because medical tapes are soft and have a certain degree of elasticity, the unfixed tapes are prone to displacement, wrinkling or twisting under the force generated by the high-speed rotation of the slitting blade. This will result in uneven width and jagged edges of the slitting tapes, failing to meet the strict size standards of medical tapes and directly affecting product quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slitting device for medical tape production, comprising a workbench and a tape body. A fixing device is fixedly installed on the front side of the workbench surface, and an adjusting device is fixedly installed on the rear side of the workbench surface. The adjusting device is equipped with multiple sets of electric slitting blades. The fixing device includes limiting seats fixedly installed at both ends of the front side of the workbench surface.

The first hinge rod is connected to a clamping block through a second hinge rod. The movable ring is connected to a positioning plate through a movable sleeve. The positioning plate is fixedly connected to a fixing block through an L-shaped connecting rod. The positioning plate is connected to a rotating disk through a threaded rod.

[0006] As a preferred embodiment, the fixing plate is fixedly installed on the surface of the limiting seat, the fixing shaft is fixedly installed on one side surface of the fixing plate, the movable ring is slidably connected to the circumferential surface of the fixing shaft, three sets of first hinge rods are provided, and one end of each first hinge rod is rotatably installed on the circumferential surface of the movable ring. Three sets of second hinge rods are provided, and one end of each first hinge rod is rotatably connected to the circumferential surface of one end of the fixing shaft. The ends of the three sets of first hinge rods away from the movable ring are respectively rotatably connected to the surfaces of the three sets of second hinge rods. Three sets of clamping blocks are provided, and each clamping block is rotatably connected to the ends of the three sets of second hinge rods away from the fixing shaft.

[0007] As a preferred embodiment, the side surface of the clamping block away from the second hinge rod is arc-shaped and adapted to the inner wall of the tape body.

[0008] As a preferred embodiment, one end of the movable sleeve is fixedly connected to the movable ring, and the other end is fixedly connected to the positioning plate. Both the movable sleeve and the positioning plate are slidably connected to the circumferential surface of the fixed shaft. Two sets of threaded rods are provided, each threadedly connected to the inside of the fixed plate. One end of each set of threaded rods is rotatably connected to the inside of the positioning plate. The rotating disk is fixedly installed at the end of the threaded rod away from the positioning plate. Multiple sets of L-shaped connecting rods are provided, with one end fixedly installed on both sides of the positioning plate. Multiple sets of fixing blocks are provided, each fixedly installed on the other end of the multiple sets of L-shaped connecting rods.

[0009] As a preferred embodiment, the adjustment device includes a fixed frame fixedly installed on the rear side of the workbench surface. Small motors are fixedly installed on both sides of the rear end of the workbench surface, and lead screws are fixedly installed on the output ends of the two sets of small motors. Fixed rods are fixedly installed on both sides between the top of the fixed frame and the surface of the workbench. Threaded sliders are threadedly connected to the circumferential surfaces of the two sets of lead screws, and the two sets of threaded sliders are slidably connected to the circumferential surfaces of the two sets of fixed rods.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting a fixing device, when fixing the tape body, the limiting groove on the surface of the limiting seat first positions it laterally to prevent displacement during the cutting process. Then, the operator rotates the rotating disk to drive the threaded rod to rotate, so that the positioning plate moves along the fixed axis. The moving sleeve drives the moving ring, which in turn pulls the first hinge rod and the second hinge rod to realize the opening and closing of the three sets of clamping blocks, so as to adaptively clamp the tape body. At the same time, the movement of the positioning plate will also push the L-shaped connecting rod and the fixing block to make them fit tightly against both ends of the tape body, further enhancing the fixing effect, ensuring the stability of the tape body during the cutting process, and effectively improving the cutting accuracy.

[0013] 2. By setting up an adjustment device, the operator can flexibly slide the positioning slider on the circumferential surface of the metal rod to adjust the position of the electric slitting blade according to the slitting specifications of the medical tape. Precise positioning and fixation are achieved by tightening the locking bolt. At the same time, the small motor drives the lead screw to rotate, and the threaded slider moves smoothly under the guidance of the lead screw and the fixed rod, driving the electric slitting blade to move quickly and accurately. This electric adjustment method replaces the traditional manual operation, significantly improving adjustment efficiency and positioning accuracy, greatly shortening adjustment time, reducing errors, and effectively ensuring the quality and efficiency of medical tape slitting operations.

Detailed Implementation

[0020] 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.

[0021] Please see the appendix Figure 1 - Appendix Figure 2 and appendix Figure 4 - Appendix Figure 5 A slitting device for producing medical tape includes a workbench 1 and a tape body 2. A fixing device 4 is fixedly installed on the front side of the surface of the workbench 1, and an adjusting device 5 is fixedly installed on the rear side of the surface of the workbench 1. The adjusting device 5 is equipped with multiple sets of electric slitting blades 3. The fixing device 4 includes limiting seats 401 fixedly installed at both ends of the front side of the surface of the workbench 1. The surfaces of the two sets of limiting seats 401 are provided with limiting grooves 402 that are adapted to the tape body 2. A fixing shaft 404 is fixedly installed on the surface of the limiting seat 401 through a fixing plate 403. The fixing shaft 404 is connected to a first hinge rod 406 through a movable ring 405. The first hinge rod 406 is connected to a clamping block 408 through a second hinge rod 407. The movable ring 405 is connected to a positioning plate 410 through a movable sleeve 409. The positioning plate 410 is fixedly connected to a fixing block 414 through an L-shaped connecting rod 413. The positioning plate 410 is connected to a rotating disk 412 through a threaded rod 411.

[0022] A fixed plate 403 is fixedly installed on the surface of a limiting seat 401. A fixed shaft 404 is fixedly installed on one side surface of the fixed plate 403. A movable ring 405 is slidably connected to the circumferential surface of the fixed shaft 404. Three sets of first hinge rods 406 are provided, each with one end rotatably mounted on the circumferential surface of the movable ring 405. Three sets of second hinge rods 407 are provided, each with one end rotatably connected to the circumferential surface of one end of the fixed shaft 404. The ends of the three sets of first hinge rods 406 away from the movable ring 405 rotate respectively. The clamping blocks 408 are provided with three sets and are rotatably connected to the ends of the three sets of second hinge rods 407 away from the fixed shaft 404. The ends of the three sets of first hinge rods 406 away from the moving ring 405 are rotatably connected to the middle of the three sets of second hinge rods 407. The three sets of clamping blocks 408 are rotatably connected to the ends of the three sets of second hinge rods 407 away from the fixed shaft 404. This hinge design allows the clamping blocks 408 to be adaptively adjusted according to the size of the tape body 2.

[0023] The side surface of the clamping block 408 away from the second hinge rod 407 is arc-shaped and adapted to the inner wall of the tape body 2. When fixing the tape body 2, the contact area with the tape body 2 can be increased, making the fixation more secure.

[0024] One end of the movable sleeve 409 is fixedly connected to the movable ring 405, and the other end is fixedly connected to the positioning plate 410. Both the movable sleeve 409 and the positioning plate 410 are slidably connected to the circumferential surface of the fixed shaft 404. Two sets of threaded rods 411 are provided and are threadedly connected to the inside of the fixed plate 403. One end of the two sets of threaded rods 411 is rotatably connected to the inside of the positioning plate 410. The rotating disk 412 is fixedly installed on the end of the threaded rods 411 away from the positioning plate 410. Multiple sets of L-shaped connecting rods 413 are provided and one end is fixedly installed on both sides of the positioning plate 410. Multiple sets of fixing blocks 414 are provided and fixedly installed on the other end of the multiple sets of L-shaped connecting rods 413. Multiple sets of L-shaped connecting rods 413 are installed on both sides of the positioning plate 410, and the other end is connected to multiple sets of fixing blocks 414. The positioning plate 410 moves to push the fixing blocks 414, which helps to fix both ends of the tape body 2 and strengthens the fixing effect.

[0025] Specifically, the limiting groove 402 on the surface of the limiting seat 401 initially positions the tape body 2, preventing lateral displacement during the cutting process. Simultaneously, rotating the rotating disk 412 drives the threaded rod 411 to rotate, causing the positioning plate 410 to move on the fixed shaft 404. This, in turn, drives the moving ring 405 to move through the moving sleeve 409, pulling the first hinge rod 406 and the second hinge rod 407. This causes the three sets of clamping blocks 408 to move closer or further apart, adaptively clamping and fixing the tape body 2. At the same time, the movement of the positioning plate 410 pushes multiple L-shaped connecting rods 413 and fixing blocks 414 to move, ensuring that the fixing blocks 414 are in complete contact with both ends of the tape body 2, guaranteeing the stability of the tape body 2 during cutting and effectively improving cutting accuracy.

[0026] Please see the appendix Figure 1 - Appendix Figure 3The adjusting device 5 includes a fixed frame 501 fixedly installed on the rear side of the workbench 1 surface. Small motors 502 are fixedly installed on both sides of the rear end of the workbench 1 surface, and lead screws 503 are fixedly installed at the output ends of both sets of small motors 502. Fixed rods 504 are fixedly installed on both sides between the top of the fixed frame 501 and the surface of the workbench 1. Threaded sliders 505 are threadedly connected to the circumferential surfaces of both sets of lead screws 503, and the two sets of threaded sliders 505 are slidably connected to the circumferential surfaces of the two sets of fixed rods 504. Two sets of metal rods 506 are fixedly installed between the two sets of threaded sliders 505. Multiple sets of positioning sliders 507 are slidably connected to the circumferential surface of rod 506. Multiple sets of electric slitting blades 3 are fixedly installed on one side surface of the multiple sets of positioning sliders 507. The circumferential surface of screw 503 is threadedly connected to threaded slider 505. The threaded slider 505 is slidably connected to fixed rod 504 to ensure smooth movement. Two metal rods 506 are fixed between two sets of threaded sliders 505. Multiple sets of positioning sliders 507 are slidably connected to the circumferential surface of metal rod 506. The electric slitting blades 3 are fixed to one side of the positioning sliders 507. The layout of electric slitting blades 3 can be flexibly adjusted by adjusting the position of positioning sliders 507 to meet different tape slitting requirements.

[0027] The ends of the two sets of lead screws 503 away from the worktable 1 are rotatably connected to the top inner side of the fixed frame 501. The internal threads of the multiple sets of positioning sliders 507 are all connected to locking bolts 508. After the operator adjusts the position of the positioning sliders 507 and the electric slitting blade 3, he tightens the locking bolts 508 to fix the positioning sliders 507 on the metal rod 506, so as to prevent the electric slitting blade 3 from shifting during slitting and to ensure slitting accuracy and safety.

[0028] Specifically, multiple sets of positioning sliders 507 can slide on the circumferential surface of the metal rod 506. The operator can flexibly adjust the position of each electric slitting blade 3 according to specific slitting requirements, and then fix it by tightening the locking bolts 508. This meets the production of medical tapes with different specifications and slitting requirements. The small motor 502 drives the lead screw 503 to rotate, so that the threaded slider 505 can move smoothly under the cooperation of the lead screw 503 and the fixed rod 504. This adjustment method can move the electric slitting blade 3 quickly and accurately to slit the tape body 2. Compared with manual adjustment, it greatly improves the adjustment efficiency and accuracy, reduces the adjustment time and error, and further improves the efficiency and quality of the slitting operation.

[0029] Working principle of this utility model: This utility model is a slitting device for medical tape production. First, the tape body 2 is placed on the limiting seat 401 of the fixing device 4 on the front side of the workbench 1. The limiting groove 402 on the surface of the limiting seat 401 initially positions the tape body 2 to prevent lateral displacement during slitting. Next, the operator rotates the rotating disk 412, which drives the threaded rod 411 to rotate, causing the positioning plate 410 to move on the fixed shaft 404. The positioning plate 410 drives the moving ring 405 to move through the moving sleeve 409, pulling the first hinge rod 406 and the second hinge rod 407, so that the three sets of clamping blocks 408 move away from each other and abut against the inner wall of the tape body 2, thus adaptively clamping and fixing the tape body 2. At the same time, the movement of the positioning plate 410 pushes multiple L-shaped connecting rods 413 and fixing blocks 414 to move until the fixing blocks... 414 is in complete contact with both ends of the tape body 2 to ensure the stability of the tape body 2 during the slitting process. Before slitting, the operator can flexibly adjust the position of the electric slitting blade 3 on the adjusting device 5 according to the specific slitting requirements. Multiple sets of positioning sliders 507 can slide on the circumferential surface of the metal rod 506. After the operator adjusts the position of the electric slitting blade 3, the locking bolts 508 inside the positioning sliders 507 are tightened for fixation. Then, the small motors 502 on both sides of the rear end of the worktable 1 are started. The small motors 502 drive the lead screw 503 to rotate, so that the threaded slider 505 moves smoothly under the cooperation of the lead screw 503 and the fixed rod 504, thereby driving the electric slitting blade 3 to slit the fixed tape body 2. This adjustment method can move the electric slitting blade 3 quickly and accurately, improving the efficiency and quality of the slitting operation. The whole process is over.

[0030] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
