[0002] With the continuous advancement of the medical industry and the increasing demands of consumers for product quality, transparent PU film waterproof dressings with cores, as an important medical dressing, are experiencing a sustained increase in market demand. In the production process of transparent PU film waterproof dressings with cores, shearing equipment is required to accurately and efficiently cut the transparent PU film waterproof dressings with cores.

[0003] However, existing cutting equipment for producing transparent PU film core waterproof dressings is not convenient for fixing the transparent PU film core waterproof dressing during cutting. The transparent PU film core waterproof dressing may move or misalign during the cutting process, resulting in problems such as uneven cut edges and dimensional deviations. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for the production of transparent PU film core waterproof dressings. By setting a fixing mechanism, it solves the problems of existing cutting devices for transparent PU film core waterproof dressing production, which are inconvenient to fix the transparent PU film core waterproof dressing during cutting, and the transparent PU film core waterproof dressing may move or be misaligned during the cutting process, resulting in uneven cutting edges and dimensional deviations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a cutting device for producing transparent PU film core waterproof adhesive, including two support legs, and several fixing mechanisms and pressing mechanisms are provided on the two support legs;

[0007] A rectangular plate is provided above the two supporting legs. The fixing mechanism includes two fixing blocks fixedly connected to the bottom of the rectangular plate. A sliding rod is fixedly connected between the two fixing blocks. Two sliders are slidably connected to the outer wall of the sliding rod. A spring is fixedly connected to the side of the two sliders that are far apart from each other. The side of the two springs that are far apart from each other is fixedly connected to the two sliders respectively. A spring sheet is fixedly connected between the two sliders.

[0008] Furthermore, a plurality of sliding rods 2 are passed through the rectangular plate, and the plurality of sliding rods 2 are slidably connected to the rectangular plate. The bottom of the plurality of sliding rods 2 is fixedly connected to a clamping plate, and the top of the clamping plate is fixedly connected to a spring sheet.

[0009] Furthermore, a workbench is fixedly connected between the two support legs, and a shearing blade is fixedly connected to the bottom of the rectangular plate.

[0010] Furthermore, the pressing mechanism includes a support frame fixedly connected to the top of the two support legs, and the support frame has a rectangular groove.

[0011] Furthermore, a hinge rod one is hingedly provided inside the rectangular groove, a hinge rod two is provided inside the rectangular groove, and two hinge rods three are hingedly provided at the bottom of both the hinge rod one and the hinge rod two.

[0012] Furthermore, a connecting block is hinged between several of the hinge rods, and the bottom of the connecting block is fixedly connected to the rectangular plate.

[0013] Furthermore, a hinge block is fixedly connected to the top of the support frame, and a hydraulic cylinder is hinged to the top of the hinge block. The output shaft of the hydraulic cylinder is hinged to the hinge rod one, and a hinge rod four is hinged to the right side of the two hinge rods three located on the right side.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting a fixing mechanism, when the pressing mechanism drives the rectangular plate down, the fixing mechanism will also descend. The clamping plate in the fixing mechanism will first contact the adhesive and be squeezed, thereby transmitting the force to the spring plate. The spring plate stretches and drives the two sliders to move away from each other, thereby compressing the two springs. At this time, the elastic force of the spring and the spring plate will be transmitted back to the clamping plate, thereby fixing the adhesive below it. The rectangular plate then descends and drives the shearing blade to cut the adhesive. Thus, the cutting of one adhesive is completed. This allows the adhesive to be pressed and fixed before cutting the transparent PU film waterproof adhesive with core, thereby avoiding the adhesive from moving or misaligning during the cutting process, resulting in uneven cutting edges and dimensional deviations.

[0016] 2. By setting up a pressing mechanism, first place the device in the corresponding position, then place the transparent PU film core waterproofing tape to be cut on the worktable, align the cutting position with the shearing blade, and then open the hydraulic cylinder on the hinge block to control its stretching. The hydraulic cylinder drives the hinge rod one in the rectangular groove to rotate. The hinge rod one drives the two hinge rods three behind it to rotate through the hinge rod four. At the same time, the hinge rod one also drives the hinge rod three below it to rotate, so that the four hinge rods three drive the connecting block below to descend. The connecting block drives the rectangular plate to descend, and the descending of the rectangular plate will drive the fixing mechanism to descend to complete the cutting. This allows the pressing mechanism to automatically descend with the shearing blade and pressure roller to perform fixing and cutting, reducing the time and steps of manual operation, reducing the impact of human fatigue or distraction, and further ensuring the continuity and stability of the production line.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-5As shown, this utility model is a cutting device for producing transparent PU film core waterproof dressings. It includes two support legs 1, with several fixing mechanisms 2 and a pressing mechanism 3 mounted on the two support legs 1. A rectangular plate 111 is positioned above the two support legs 1. The fixing mechanisms 2 include two fixing blocks 211 fixedly connected to the bottom of the rectangular plate 111. A sliding rod 212 is fixedly connected between the two fixing blocks 211. Two sliders 213 are slidably connected to the outer wall of the sliding rod 212. Springs 214 are fixedly connected to the sides of the two sliders 213 that are far apart from each other. Two sliders 213 are fixedly connected to each other, and a spring plate 215 is fixedly connected between the two sliders 213. Several sliding rods 216 pass through the rectangular plate 111, and the sliding rods 216 are all slidably connected to the rectangular plate 111. A clamping plate 217 is fixedly connected to the bottom of the sliding rods 216, and the top of the clamping plate 217 is fixedly connected to the spring plate 215. A worktable 112 is fixedly connected between the two support legs 1, and a shearing blade 113 is fixedly connected to the bottom of the rectangular plate 111. By setting up a fixing mechanism, the transparent PU film core waterproof adhesive can be pre-cut before cutting. The adhesive is pressed down and fixed to prevent the adhesive from moving or misaligning during the cutting process, which would result in uneven cut edges and dimensional deviations. The pressing mechanism 3 includes a support frame 311 fixedly connected to the top of the two support legs 1. A rectangular groove 312 is provided on the support frame 311. A hinge rod 313 and a hinge rod 314 are hinged in the rectangular groove 312. Two hinge rods 315 are hinged at the bottom of both the hinge rod 313 and the hinge rod 314. Connecting blocks 316 are hinged between several hinge rods 315. The bottom is fixedly connected to the rectangular plate 111, and the top of the support frame 311 is fixedly connected to the hinge block 317. The top of the hinge block 317 is hinged to the hydraulic cylinder 318. The output shaft of the hydraulic cylinder 318 is hinged to the hinge rod 313. The right side of the two hinge rods 315 on the right side is hinged to the hinge rod 319. By setting the pressing mechanism, the pressing mechanism 3 can automatically lower the shearing blade and pressure roller to fix and shear, reducing the time and steps of manual operation, reducing the impact of human fatigue or distraction, and further ensuring the continuity and stability of the production line.

[0028] A specific application of this embodiment is as follows: In use, first place the device in the corresponding position, then place the transparent PU film core waterproof adhesive to be cut on the workbench 112, align the area to be cut with the cutting blade 113, and then open the hydraulic cylinder 318 on the hinge block 317 to control its extension. The hydraulic cylinder 318 drives the hinge rod 313 in the rectangular groove 312 to rotate. The hinge rod 313 drives the two rear hinge rods 315 to rotate via the hinge rod 319. Simultaneously, the hinge rod 313 also drives the hinge rod 315 below it to rotate, thus rotating the four hinge rods 315. The connecting block 316 below it descends, which in turn causes the rectangular plate 111 to descend. The descent of the rectangular plate 111 causes the fixing mechanism 2 to descend. The clamping plate 217 in the fixing mechanism 2 will first contact the adhesive and be squeezed, thereby transmitting the force to the spring plate 215. The spring plate 215 stretches and causes the two sliders 213 to move away from each other, thereby compressing the two springs 214. At this time, the elastic force of the springs 214 and the spring plate 215 will be transmitted back to the clamping plate 217, thereby fixing the adhesive below it. The rectangular plate 111 then descends and causes the shearing blade 113 to cut the adhesive, thus completing the cutting of one adhesive application.
