[0002] Medical single sheets are a common type of medical supplies. Currently, when producing medical single sheets, usually, a roll of non-woven fabric is transported and folded to form a semi-finished product of the medical single sheet to be cut, and then a cutting device is used to cut the semi-finished product of the medical single sheet into the required length specifications of the medical single sheet. However, when the existing cutting device cuts the semi-finished product of the medical single sheet, some use manual assistance to feed the semi-finished product of the medical single sheet forward. In this way, during use, it is necessary to continuously measure the length to be cut, which is not convenient for cutting the semi-finished product of the medical single sheet and will affect the production efficiency of the medical single sheet. Therefore, there are still drawbacks and deficiencies in the prior art. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the purpose, technical solutions and beneficial effects of the utility model clearer, the following further describes the embodiments of the utility model in detail with reference to the drawings.

[0022] As shown Figures 1 to 4 in the figure, the utility model provides a cutting device for the production of medical single sheets, which includes a workbench 7. A feeding mechanism 6, a pressing mechanism 4 that can be telescoped in the vertical direction, and a lifting mechanism 3 are sequentially installed on the tabletop of the workbench 7. The feeding mechanism 6, the pressing mechanism 4, and the lifting mechanism 3 are relatively positioned. Specifically, during use, the feeding mechanism 6 can guide the semi-finished medical single sheet 8; the pressing mechanism 4 can press the semi-finished medical single sheet 8 in the extended state; and the lifting mechanism 3 can lift the end of the semi-finished medical single sheet 8 to a horizontal state in the extended state. A cutting mechanism 5 that can be telescoped in the vertical direction is installed on the side of the pressing mechanism 4 away from the feeding mechanism 6. The cutting mechanism 5 can cut the semi-finished medical single sheet 8. The cutting mechanism 5 is located on the side of the lifting mechanism 3 away from the pressing mechanism 4 and obliquely above the lifting mechanism 3. A horizontal displacement mechanism 2 is installed on the side of the cutting mechanism 5 away from the pressing mechanism 4. The horizontal displacement mechanism 2 is installed on the tabletop of the workbench 7, and a grasping mechanism 1 that can reciprocate along the horizontal displacement mechanism 2 and can be opened and closed is installed on the horizontal displacement mechanism 2. The grasping mechanism 1 is relatively positioned with the pressing mechanism 4. Specifically, the grasping mechanism 1 can release the semi-finished medical single sheet 8 in the open state; and in the closed state, the grasping mechanism 1 can grasp the semi-finished medical single sheet 8.

[0023] During use, when the cutting mechanism 5 cuts the semi-finished medical single sheet 8, the pressing mechanism 4 and the grasping mechanism 1 can respectively fix the two sides of the cutting position on the semi-finished medical single sheet 8, which can facilitate the cutting mechanism 5 to cut the semi-finished medical single sheet 8. Then, after cutting is completed, the medical single sheet finished product 8 can be taken off from the grasping mechanism 1 manually or by setting a material taking mechanism. At the same time, the end of the semi-finished medical single sheet 8 can be lifted to a horizontal state by the lifting mechanism 3. At this time, the horizontal displacement mechanism 2 can drive the grasping mechanism 1 to grasp the semi-finished medical single sheet 8, then retract the pressing mechanism 4, and then drive the grasping mechanism 1 to move in the reverse direction by the horizontal displacement mechanism 2 to drive the semi-finished medical single sheet 8 to feed forward until the semi-finished medical single sheet 8 is moved to a suitable position, then retract the lifting mechanism 3, and then when the pressing mechanism 4 presses the semi-finished medical single sheet 8, cutting can be carried out again. In this way, during cutting, the semi-finished medical single sheet 8 can be automatically driven to feed forward, which is convenient for cutting the semi-finished medical single sheet 8 and can improve the production efficiency of medical single sheets.

[0024] The specific setting method of the pressing mechanism 4 is as follows: As Figure 1 shown Figure 2As shown, the pressing mechanism 4 includes a support platform 41 installed on the workbench 7, and a top plate 42 is arranged above the support platform 41. Specifically, four vertically oppositely distributed first legs 43 are fixedly connected to the support platform 41, and the top plate 42 is installed between the top ends of the four first legs 43; a vertically distributed first electric telescopic rod 44 is installed on the bottom surface of the top plate 42, and the first electric telescopic rod 44 can be set as an electric push rod; the bottom end of the first electric telescopic rod 44 is a telescopic end and is connected to a pressing plate 45. Specifically, in the initial state, the telescopic end of the first electric telescopic rod 44 is in a retracted state; when in use, the medical single semi-finished product 8 is located between the pressing plate 45 and the support platform 41, and then when the telescopic end of the first electric telescopic rod 44 is extended, it can drive the pressing plate 45 to press the medical single semi-finished product 8.

[0025] The specific configuration of the material lifting mechanism 3 is as follows: Figure 1 and Figure 2 As shown, the lifting mechanism 3 includes a second electric telescopic rod 31 vertically mounted on the workbench 7, and the second electric telescopic rod 31 can be set as an electric push rod; the top of the second electric telescopic rod 31 is a telescopic end and is connected to a lifting plate 32, and the lifting plate 32 is located on the side of the cutting mechanism 5 away from the horizontal displacement mechanism 2. Specifically, the lifting plate 32 is horizontally arranged. In the initial state, the telescopic end of the second electric telescopic rod 31 is in a retracted state. At this time, the lifting plate 32 is located below the medical single semi-finished product 8 and does not affect the cutting of the medical single semi-finished product 8 by the cutting mechanism 5; and when the cutting is completed, after the telescopic end of the second electric telescopic rod 31 is extended, the lifting plate 32 can be driven to lift the end of the medical single semi-finished product 8 to a horizontal state. At this time, the end of the medical single semi-finished product 8 close to the grasping mechanism 1 is located outside the lifting plate 32, so that the grasping mechanism 1 can grasp the medical single semi-finished product 8.

[0026] The specific configuration of the cutting mechanism 5 is as follows: Figure 1 , Figure 2 and Figure 4 As shown, the cutting mechanism 5 includes a vertically distributed third electric telescopic rod 51, which can be set as an electric push rod; the bottom end of the third electric telescopic rod 51 is a telescopic end and is connected to a horizontally arranged cutting knife 52, and the top end of the third electric telescopic rod 51 is connected to a bearing plate 53, and the bearing plate 53 and the top plate 42 are connected by a second leg 54, and the cutting knife 52 is located on the side of the lifting mechanism 3 away from the pressing mechanism 4 and is located obliquely above the lifting mechanism 3. Specifically, in the initial state, the telescopic end of the third electric telescopic rod 51 is in a retracted state. At this time, the cutting knife 52 is located above the medical single semi-finished product 8; and during cutting, after the telescopic end of the third electric telescopic rod 51 is extended, the cutting knife 52 can be driven to cut the medical single semi-finished product 8.

[0027] To improve the stability of the cutting knife 52 during the lifting process, therefore, as Figure 1 , Figure 2 and Figure 4 show, two vertically opposite telescopic rods 55 are installed between the cutting knife 52 and the bearing plate 53. The third electric telescopic rod 51 is located between the two telescopic rods 55. Specifically, during use, when the third electric telescopic rod 51 drives the cutting knife 52 to lift, the telescopic rods 55 can synchronously expand and contract, thereby improving the stability of the cutting knife 52 during the lifting process.

[0028] The specific setting method of the horizontal displacement mechanism 2 is as follows: as Figures 1 to 3 shows, the horizontal displacement mechanism 2 includes two support seats 21 that are vertically opposite and installed on the workbench 7. Two horizontally opposite guide rods 22 are fixedly connected between the two support seats 21. A lead screw 23 parallel to the guide rods 22 is arranged between the two guide rods 22. Both ends of the lead screw 23 are rotatably connected to the support seats 21, and one end of the lead screw 23 is drivingly connected to a forward and reverse motor 24. A moving plate 25 is also sleeved and threadedly connected on the lead screw 23. Both sides of the moving plate 25 are respectively sleeved on the guide rods 22 and slidably connected to the guide rods 22. The material grabbing mechanism 1 is installed on the moving plate 25. Specifically, during use, the horizontal displacement mechanism 2 is located on one side of the conveying direction of the semi-finished medical single 8 and is parallel to the conveying direction of the semi-finished medical single 8. Then, when the forward and reverse motor 24 is started, the lead screw 23 can be driven to rotate. During the rotation of the lead screw 23, the moving plate 25 can be driven to move along the guide rods 22, so that the material grabbing mechanism 1 can grab the semi-finished medical single 8 and can move the material grabbing mechanism 1 in the reverse direction to drive the semi-finished medical single 8 to feed forward; in addition, the distance when the horizontal displacement mechanism 2 drives the material grabbing mechanism 1 to move in the reverse direction can be adjusted to facilitate cutting medical singles of different length specifications.

[0029] The specific setting method of the material grabbing mechanism 1 is as follows: as Figures 1 to 3As shown, the grasping mechanism 1 includes a mounting plate 11 horizontally mounted on a movable plate 25, and a side of the mounting plate 11 close to the pressing mechanism 4 is fixedly connected to a carrier frame 13 through a connecting rod 12, and the carrier frame 13 is arranged parallel to the mounting plate 11 and opposite to the pressing mechanism 4. Specifically, the carrier frame 13 is located outside the side of the horizontal displacement mechanism 2 close to the medical single semi-finished product 8; and two relatively arranged finger cylinders 14 are installed on the side of the carrier frame 13 away from the mounting plate 11, and each finger cylinder 14 is equipped with two openable and closable jaws 15, specifically, in an initial state, the two jaws 15 on the finger cylinder 14 are in an open state; when in use, the finger cylinder 14 is connected to an external air source, and then when the two jaws 15 on the finger cylinder 14 are in a closed state, the medical single semi-finished product 8 can be grasped; and when the two jaws 15 on the finger cylinder 14 are opened again, the medical single finished product 8 can be removed from the grasping mechanism 1.

[0030] The specific configuration of the material guiding mechanism 6 is as follows: Figure 1 and Figure 2 As shown, the material guiding mechanism 6 includes two supporting plates 61 which are vertically opposite to each other and installed on the workbench 7, and two material guiding rollers 62 which are horizontally opposite to each other and spaced apart are rotatably connected between the two supporting plates 61 from top to bottom, and a material guiding space which is opposite to the position of the pressing mechanism 4 can be formed between the two material guiding rollers 62. Specifically, when in use, the medical single semi-finished product 8 is located between the two guide rollers 62, and then when the grabbing mechanism 1 moves in the opposite direction to drive the medical single semi-finished product 8 to feed forward, the material guiding mechanism 6 can guide the medical single semi-finished product 8.

[0031] Furthermore, a controller is installed on the workbench 7, and the controller is electrically connected to the pressing mechanism 4, the lifting mechanism 3, the cutting mechanism 5, the horizontal displacement mechanism 2 and the grasping mechanism 1. Specifically, the controller is a PLC controller in the prior art. When in use, the controller can control the pressing mechanism 4, the lifting mechanism 3, the cutting mechanism 5, the horizontal displacement mechanism 2 and the grasping mechanism 1 to automatically perform related operations, thereby realizing automatic cutting of the medical single semi-finished product 8.
