Description

A slitting machine for producing medical cold compresses Technical Field

This invention relates to the technical field of cutting cold compresses, specifically to a cutting machine for producing medical cold compresses.

Background Technology

Cooling compresses are gel patches that use the principle of cooling therapy. They are made of polymer hydrogel and can effectively lower the temperature of the human body surface through the evaporation of water molecules. Medical cooling compresses are a type of skin care product.

A slitting machine is a mechanical device that cuts wide sheets of paper, mica tape, or film into multiple narrow strips. Existing slitting machines, when producing cold compresses, require embossing rollers to press and divide the cold compresses into specified sizes. Then, cutting rollers cut the embossed areas of the cold compresses laterally and longitudinally to obtain individual cold compresses. During operation, the cutting blades on the embossing roller are fixed at equal intervals, making it inconvenient to adjust the distance between the blades to ensure a consistent length of the cold compress. Similarly, the cutting blades on the cutting roller are fixedly mounted, making it difficult to adjust the blades to ensure consistent longitudinal and transverse cut widths and lengths. It is also difficult to adjust the horizontal position of multiple cutting blades on the slitting machine, thus hindering the ability to change the spacing between them. This prevents the simultaneous production of cold compresses of different specifications, reducing its practicality. Furthermore, when different cold compresses need to be cut, the embossing roller and cutting roller must be replaced, increasing the labor intensity of workers and reducing the processing efficiency of cold compresses.

Summary of the Invention

The purpose of this invention is to provide a medical cold compress production slitting machine that can cut cold compresses of different specifications and improves the ease of operation for workers, so as to solve the problems mentioned in the background art.

To achieve the above objectives, the present invention provides the following technical solution: a slitting machine for producing medical cold compresses, comprising an operating table, arc-shaped pressure blocks, circular pressure rings, a first cutter, a second cutter, a first distance adjustment assembly, a lifting assembly, a second distance adjustment assembly, a push-pull assembly, and a drive assembly. One end of the operating table has an inclined surface. Multiple arc-shaped pressure blocks are arranged in a circumferential array at equal intervals on the outer side of the rotating roller. The arc-shaped pressure blocks indent the cold compresses in the vertical direction of their movement. Multiple circular pressure rings are arranged at equal intervals on the outer side of the rotating shaft. A pressure ring indents the cold compress in the direction of its movement.

A second cutter is installed at one end of the operating table and near the inclined surface, cutting the indentations in the direction perpendicular to the movement of the cold compress to separate it into individual blocks. A first distance adjustment assembly is installed inside the rotating roller to adjust the distance between the arc-shaped pressure block and the outer wall of the rotating roller. A lifting assembly is installed... Mounted at both ends of the rotating roller, when the first adjusting assembly adjusts the position of the arc-shaped pressure block, the lifting assembly adjusts the height of the rotating roller.

[Corrected according to detailed rules 91, April 22, 2025]
Please refer to Figures 1-3 and 11. The push-pull assembly shown in the figures also includes a sleeve 36 that is slidably sleeved on the U-shaped rod 30. A spring 37 is sleeved between the sleeve 36 and the rectangular frame 31 and on the U-shaped rod 30. A fixing rod 38 is fixedly provided on one side of the sleeve 36. The fixing rod 38 is fixedly connected to the frame 39 on both sides of the operating table 1.

When cutting cold compresses: First, place the cold compresses to be cut on the operating table 1. Then, adjust the positions of the arc-shaped pressure block 2 and the circular pressure ring 4 according to the size specifications of the blocks to be cut. During adjustment, first adjust the distance between the arc-shaped pressure block 2 and the rotating roller 3 through the first distance adjustment component. During adjustment, rotate the handle 14 at the end of the screw 9. The rotation of the handle 14 can drive the screw 9 to rotate. At the same time, the rotation of the screw 9 can drive the nuts 10 on the positive and negative thread sections at both ends to move. Since the side wall of the nut 10 is fixed with a protrusion 11 that is slidably connected to the slide groove 8, the protrusion 11 can limit the nut 10, preventing the nut 10 from rotating synchronously with the screw 9 when the screw 9 rotates. The nut 10 is limited by the protrusion 11, so that when the screw 9 rotates, the two nuts 10 connected to the positive and negative thread sections at both ends of the screw 9 can move towards each other or in opposite directions. When the nuts 10 move towards each other, it can... The movable rod 12 between the nut 10 and the arc-shaped pressure block 2 acts as a pusher, increasing the angle between the movable rod 12 and the horizontal direction. This pushes the arc-shaped pressure block 2 away from the rotating roller 3, increasing the distance between the arc-shaped pressure block 2 and the rotating roller 3. Consequently, the distance between two adjacent arc-shaped pressure blocks 2 increases, resulting in a larger indentation distance of the arc-shaped pressure block 2 in the vertical direction of the cold compress movement, thus increasing the cutting length of the cold compress. Similarly, when the nuts 10 move in the opposite direction, the nuts 10 pull the movable rod 12, decreasing the angle between the movable rod 12 and the axial direction of the rotating roller 3. At this time, the arc-shaped pressure block 2 moves closer to the rotating roller 3, decreasing the distance between two adjacent arc-shaped pressure blocks 2. This results in a smaller indentation distance of the arc-shaped pressure block 2 in the vertical direction of the cold compress movement, thus reducing the cutting length of the cold compress. Once the arc-shaped pressure block 2 is adjusted according to the required cutting size of the cold compress, the rotation of the crank handle 14 can be stopped.

After the arc-shaped pressure block 2 is adjusted, the height of the rotating roller 3 on the operating table 1 can be adjusted by using the lifting assembly. This allows the height between the arc-shaped pressure block 2 and the operating table 1 to be adjusted so that the arc-shaped pressure block 2 makes contact with the operating table 1 when it rotates to its lowest point. In specific operation, first hold the handle and rotate the screw 18. Since the screw 18 is threadedly connected to the threaded hole 16 at the top of the guide rail 15, the screw 18 can be raised and lowered in the vertical direction of the guide rail 15 when rotated. Since one end of the screw 18 is rotatably connected to the lifting block 17, and the lifting block 17 is slidably mounted on the guide rail 1... 5. The lifting block 17 can be limited. Under the action of the screw 18, the lifting block 17 can slide up and down inside the guide rail 15. The lifting block 15 is rotatably connected to the hollow tube 13, and one end of the hollow tube 13 is fixedly connected to the rotating roller 3. When the lifting block 17 moves up and down inside the guide rail 15, it can synchronously drive the rotating roller 3 to move up and down in the vertical direction. The movement of the rotating roller 3 can synchronously drive the arc-shaped pressure block 2 to move up and down. When the arc-shaped pressure block 2 rotates to the lowest point, it contacts and presses against the table surface of the operating table 1. At this time, the rotation of the screw 18 can be stopped.

When adjusting the lifting assembly, the lifting assembly can synchronously drive the movement of the second adjusting assembly on one side. When the screw 18 in the lifting assembly drives the lifting block 17 to move up and down in the vertical direction of the guide rail 15, it can synchronously drive the lifting plate 22 on one side to move up and down in the vertical direction through the support rod 26. Since a vertical groove 23 is opened in the middle of the lifting plate 22, and inclined grooves 24 are symmetrically opened on both sides of the vertical groove 23, and a hanging rod 58 is slidably installed inside both the vertical groove 23 and the inclined groove 24, when the lifting plate 22 is raised and lowered, the inclined groove 24 can push the hanging rod 58, while the hanging rod 58 in the vertical groove 23 remains stationary. This allows the hanging rods 58 on both sides to move away from or closer to the middle hanging rod 58, thereby adjusting the distance between two adjacent hanging rods 58. Since a slider 20 is fixedly installed at one end of the hanging rod 58, and the slider 20... The slider 20 is located inside the slide rail 21. When the rod 58 is pushed by the inclined groove 24, the slider 20 moves in the horizontal direction of the slide rail 21, thus realizing the horizontal movement of the rod 58 and avoiding the vertical movement of the rod 58. This improves the stability of the slider 20 and the rod 58 sliding in the horizontal direction. Since the end of the rod 58 away from the slider 20 is fixedly connected to one side of the arc-shaped cover 19, the rod 58 can drive the arc-shaped cover 19 to move horizontally in sync. Since the arc-shaped cover 19 is placed on the circular pressure ring 4, the movement of the arc-shaped cover 19 can drive the circular pressure ring 4 to move in different directions, thus adjusting the distance between two adjacent circular pressure rings 4. The circular pressure rings 4 rotate synchronously under the rotation of the rotating shaft 5 to make indentations on the cold compress. At this time, the distance between two adjacent circular pressure rings 4 is adjustable, which can realize the adjustment of the distance between two adjacent indentations.

When the lifting block 17 moves upward, the distance between adjacent arc-shaped pressure blocks 2 increases, and the lifting block 17 drives the lifting plate 22 to rise, which increases the distance between two adjacent hanging rods 58 and increases the distance between the circular pressure rings 4. This allows for the widening and lengthening of the cold compress. When the lifting block 17 moves downward, the distance between two adjacent arc-shaped pressure blocks 2 decreases, and the lifting block 17 drives the lifting plate 22 to fall, which decreases the distance between two adjacent hanging rods 58 and reduces the distance between the circular pressure rings 4. This allows for the shortening and narrowing of the cold compress.

The cold compress is made by two arc-shaped pressure blocks 2 with equidistant indentations on the surface along the axial direction of the rotating roller 3. When the circular pressure ring 4 rotates, it can make indentations on the cold compress along its movement direction, and the indentations are perpendicular to the indentations made by the arc-shaped pressure blocks 2. At this time, the entire cold compress can be divided into block-shaped cold compresses by indentation, and the hydrogel on the cold compress moves to the center position on both sides of the indentation, reducing the amount of hydrogel at the indentation position and avoiding the leakage of hydrogel during cutting, which can effectively reduce the waste of hydrogel.

After the whole cold compress is pressed into block-shaped cold compresses by the arc-shaped pressing block 2 and the circular pressing ring 4, the first cutter 6 and the second cutter 7 are used to cut the indentation, so that the pressed cold compresses are formed into independent block-shaped cold compresses.

During installation, the first cutter 6 is installed on one side of the arc-shaped cover 19, so that when the distance between two adjacent arc-shaped covers 19 is adjusted, the distance between two adjacent first cutters 6 can also be adjusted. The first cutter 6 is located at the center of one side of the circular pressure ring 4. After the circular pressure ring 4 makes an indentation on the cold compress in the moving direction, the first cutter 6 will cut the center of the indentation. At this time, the cold compress can be cut into strips and conveyed by the drive assembly. The strips of cold compress are then conveyed to the second cutter 7 for secondary cutting.

When the cold compress strip, cut by the first cutter 6, is conveyed by the drive assembly to the second cutter 7, the drive assembly drives the push-pull assembly to rotate, causing the active tooth 35 in the push-pull assembly to rotate. The rotation of the active tooth 35 drives the driven tooth 34 on one side to rotate. When the driven tooth 34 rotates, it drives the rotating rod 33 on one side of the driven tooth 34 to rotate, which in turn causes the push rod 32 to rotate. The rotation of the push rod 32 pushes the rectangular frame 31. When the push rod 32 pushes the rectangular frame 31 downward, the rectangular frame 31 simultaneously drives the second cutter 7 to descend via the U-shaped rod 30. As the second cutter 7 descends, it cuts the indentation made by the arc-shaped pressure block 2 on the strip cold compress. This allows the cold compress to be cut into individual block-shaped cold compresses. The cold compresses are free of hydrogel at the edges, with the hydrogel in the center, avoiding adhesion between the hydrogel at the edges and the packaging bag during subsequent packaging operations, thus improving the convenience of cold compress packaging. This also facilitates the cutting of the cold compresses after indentation.

The device has a simple structure and is easy for operators to use. By adding an arc-shaped pressure block 2, a circular pressure ring 4, a first cutter 6, a second cutter 7, a first distance adjustment component, a lifting component, a second distance adjustment component, a push-pull component, and a drive component, the distance between two adjacent arc-shaped pressure blocks 2 and two adjacent circular pressure rings 4 can be adjusted. This facilitates the cutting of the entire cold compress into individual blocks of different sizes, avoiding the need to replace the pressure ring roller and the cutting roller when cutting different cold compresses into different sizes. This effectively reduces the labor intensity of operators and improves the work efficiency of the hot compress cutting operation.

The figures show an operating table 1, an arc-shaped pressure block 2, a circular pressure ring 4, a first cutter 6, a second cutter 7, a first adjustment assembly, a lifting assembly, a second adjustment assembly, a push-pull assembly, and a drive assembly. One end of the operating table 1 has an inclined surface. Multiple arc-shaped pressure blocks 2 are arranged in a circumferential array at equal intervals on the outside of the rotating roller 3, and the arc-shaped pressure blocks 2 indent the cold compress in the vertical direction of its movement.

Near the inclined end, the second cutter 7 cuts the indentation in the vertical direction of the cold compress movement, cutting the cold compress into individual pieces; the first distance adjustment component is installed inside the roller 3 to adjust the distance between the arc-shaped pressure block 2 and the outer wall of the roller 3; the lifting component is installed at both ends of the roller 3, and when the first distance adjustment component adjusts the position of the arc-shaped pressure block 2, the lifting component adjusts the height of the roller 3; the second distance adjustment component is installed on one side of the circular pressure ring 4 to adjust the distance between two adjacent circular pressure rings 4, and the second distance adjustment component is connected to the lifting component; the push-pull component is installed at both ends of the second cutter 7 to push and pull the second cutter 7 back and forth; the drive component is installed on both sides of the operating table 1 to drive the roller 3, the rotating shaft 5 and the push-pull component, and to convey the cold compress placed on the operating table 1;

Please refer to Figures 1-3. The drive assembly shown includes a first conveying roller 40 and a second conveying roller 41 located on both sides of the rotating shaft 5. Gears 42 are fixedly provided at both ends of the first conveying roller 40, the second conveying roller 41, the rotating roller 3, and the rotating shaft 5. The gears 42 are connected by meshing with each other through a toothed chain 43. A guide wheel 44 is provided between the first conveying roller 40 and the rotating shaft 5 and located on the frame 39. The guide wheel 44 contacts the outer side wall of the toothed chain 43. The driving tooth 35 is fixedly sleeved on the second conveying roller 41. Both ends of the first conveying roller 40, the rotating shaft 5, and the second conveying roller 41, as well as one end of the rotating rod 33, are rotatably connected to the frame 39. The frame 39 is fixedly installed on the side wall of the operating table 1. A tensioning assembly is provided between the first conveying roller 40 and the rotating roller 3. One end of the rotating shaft 5 is connected to the output end of the motor 50.

Please refer to Figures 1-3, 11 and 12. The tensioning assembly shown includes a tensioning tooth 45 that meshes with the inner side of the toothed chain 43. A shaft 59 is fixedly provided on one side of the tensioning tooth 45. An adjusting block 46 is rotatably provided at the end of the shaft 59 away from the tensioning tooth 45. The adjusting block 46 is slidably disposed inside the adjusting groove 47. Multiple adjusting screw holes 48 are equally spaced on the side wall of the adjusting groove 47. The internal threads of the adjusting screw holes 48 are provided with locking bolts 49 that are threadedly connected to the adjusting block 46. One end of the adjusting groove 47 is fixedly connected to the side wall of the bracket 25.

In this embodiment, during use, by starting the motor 50 in the drive assembly, the rotating roller 3, rotating shaft 5, first conveying roller 40, second conveying roller 41 and push-pull assembly can be driven to work synchronously. When the motor 50 moves, it can drive the rotating shaft 5 at the output end to rotate. Gears 42 are fixedly provided at both ends of the rotating shaft 5 and at both ends of the rotating roller 3, the first conveying roller 40 and the second conveying roller 41. The gears 42 are meshed with each other through a toothed chain 43. When the rotating shaft 5 rotates, it can drive the rotating roller 3, the first conveying roller 40 and the second conveying roller 41 to rotate synchronously through the toothed chain 43. Since the first and second conveying rollers are in contact with the cold compress on the operating table 1, when the first and second conveying rollers rotate, they can push the cold compress, so that the cold compress moves on the operating table 1, realizing the conveying function of the cold compress.

The rotating roller 3 can drive the arc-shaped pressure block 2 installed on its side wall to make a first indentation on the moving cold compress. At the same time, the rotating shaft 5 drives the circular pressure ring 4 to make a second indentation on the cold compress. The first indentation and the second indentation are perpendicular to each other, so that the whole cold compress can be formed into a block-shaped cold compress.

When the second conveyor roller 41 rotates, it can drive the push-pull assembly to move, causing the second cutter 7 to rise and fall in the vertical direction, thus cutting at the position of the first indentation. This ensures the continuity of the first indentation, the second indentation, and the cutting during the cold compress cutting process, improving ease of use. The same motor can drive the rotating roller 3, the rotating shaft 5, the first conveyor roller 40, and the second conveyor roller 41 simultaneously, effectively reducing the investment in drive equipment and lowering costs.

After adjusting the lifting assembly, the tension of the gear chain in the drive assembly needs to be adjusted. To adjust, first unscrew the locking bolt 49 in the adjusting screw hole 48 on one side of the adjusting groove 47, which is threaded onto the adjusting block 46. Then, push the adjusting block 46 into the adjusting groove 47. At this point, the adjusting block 46 can drive the tensioning gear 45 at one end to rise and fall synchronously via the shaft 59. The tensioning gear 45 then provides external support to the inner side of the gear chain 43, keeping the gear chain 43 in a tensioned state. Once the tensioning gear 45 is in a tensioned state, stop adjusting the tensioning gear. The sliding of the adjusting block 46, and then the tightening bolt 49 is screwed into the corresponding adjusting screw hole 48 on one side of the adjusting block 46 and threadedly connected to the adjusting block 46, can fix the adjusting block 46. When the tensioning tooth 45 tensions the tooth chain 43 external support, it can improve the tightness of the meshing between the tooth chain 43 and the gear 42, realize the stability of the rotation driven by the tooth chain 43 and the gear 42, and avoid slippage between the tooth chain 43 and the gear 42, thereby improving the rotational stability of the rotating roller 3, the rotating shaft 5, the first conveying roller 40 and the second conveying roller 41.

Please refer to Figure 1. The operating table 1 in the figure is provided with a first roller 53 and a second roller 54 at the end away from the inclined plane. Both ends of the first roller 53 and the second roller 54 are rotatably connected to the mounting frame 55.
