[0032] See also Figure 2In order to prevent the cut medical bag from being folded in half, the lifting mechanism 2 in this embodiment includes an infrared ranging sensor 201, a protection box 202, a lifting plate 203, an electric push rod 204, four connecting rods 205, a positioning plate 206, a support plate 207 and a forward assembly. The infrared ranging sensor 201 and the protection box 202 are both fixed on the upper surface of the conveying device 4. The model of the infrared ranging sensor 201 is KTR-GP2D12. The electric push rod 204 is fixed on the bottom wall of the inner cavity of the protection box 202. The lifting plate 203 is fixed on the outside of the output shaft of the electric push rod 204.

Two positioning plates 206 are fixed on the upper surface of the support plate 207. The forward assembly is arranged on the back wall of the inner cavity of the support plate 207.
[0033] The protection box 202 is in the shape of a rectangular parallelepiped with a hollow interior and a missing upper surface. A rubber pad is fixed to the upper surface of the protection box 202, so that the output shaft of the electric push rod 204 can extend upward to drive the lifting plate 203 to move upward.

An installation groove is provided on the front wall of the inner cavity of the support plate 207, and a bearing is fixed inside the installation groove. The rotating rod 208 is fixed inside the bearing, so that the rotating rod 208 rotates with the roller 209 without driving the support plate 207 to rotate together.
[0035] It should be noted that the lifting mechanism 2 detects the height of the lifting plate 203 through the infrared ranging sensor 201, and thus cooperates with the controller to control the electric push rod 204 to drive the lifting plate 203 to rise each time, and then controls the support plate 207 to rise each time so that the height of the medical bag that has not been cut is lower than the height of the medical bag that has not been cut, thereby avoiding the problem of the medical bag colliding with the medical bag that has been cut before and causing it to be folded.
[0036] See also Figure 3 In order to stack the medical bags to a certain number, the shielding mechanism 3 in this embodiment includes a limit rod 301, a fixed box 302, a limit block 303, a cylinder 304, an interception seat 305 and a rubber plate 306. The fixed box 302 is fixed on the upper surface of the conveying device 4, the cylinder 304 is fixed on the top wall of the inner cavity of the fixed box 302, the interception seat 305 is fixed on the outer side of the output shaft of the cylinder 304 and the interception seat 305 is located inside the conveying device 4, the two limit rods 301 are fixed to the inside of the interception seat 305, the limit rod 301 is slidably connected to the inside of the fixed box 302, the two limit blocks 303 are respectively fixed on the upper surfaces of the two limit rods 301, and the rubber plate 306 is fixed on the lower surface of the interception seat 305. When the rubber plate 306 is in contact with the conveying device 4, the distance between the interception seat 305 and the support plate 207 is greater than one to three millimeters of the length of the medical bag after cutting.
[0037] In this embodiment, a limiting hole is provided on the lower surface of the fixed box 302 for the limiting rod 301 to pass through, and the limiting rod 301 is slidably connected to the fixed box 302 through the limiting hole, and a limiting groove is provided inside the fixed box 302 for the limiting block 303 to be slidably connected. The control method of this application is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model no longer explains the control method and circuit connection in detail.
[0038] It should be noted that the shielding mechanism 3 blocks the medical bags through the cooperation of the limit rod 301, the fixed box 302, the limit block 303, the interception seat 305 and the rubber plate 306, so that the medical bags can be stacked together, and the interception is released when a certain number of medical bags are stacked, so that a certain number of medical bags can be stacked into a group for subsequent packaging and processing.
[0039] The working principle of the above embodiment is:
[0040] (1) When the conveyor 4 is started, the upper surface of the conveyor belt on the support plate 207 is attached. At this time, the cut medical bag transported by the conveyor 4 moves along the slope on the right side of the support plate 207 to the support plate 207. After the medical bag moves to the set position, the conveyor 4 stops transporting. At this time, the cutting device starts to cut the medical bag. Then the drive motor 211 is started. The drive motor 211 drives the rotating shaft 210 to rotate through the output shaft, thereby driving the roller 209 to rotate. The roller 209 cooperates with the outer rubber pad to drive the cut medical bag to move to the left, leave the support plate 207 and fall onto the conveyor 4. At the same time, the conveyor 4 is started again, and the electric push rod 204 is started. The electric push rod 204 drives the lifting plate 203 through the output shaft. The lifting plate 203 moves upward, and drives the support plate 207 to move upward a distance through the connecting rod 205. At the same time, the infrared distance sensor 201 measures the rising height of the lifting plate 203. After the lifting plate 203 rises to the set height each time, the electric push rod 204 is closed, so that the height of the uncut medical bag is higher than the cut medical bag. The lifting mechanism 2 detects the height of the lifting plate 203 through the infrared distance sensor 201, and thus cooperates with the controller to control the electric push rod 204 to drive the lifting plate 203 to rise each time, and then controls the support plate 207 to rise each time, so that the height of the uncut medical bag can be lower than the height of the uncut medical bag, thereby avoiding the problem of the medical bag colliding with the previously cut medical bag after cutting, causing it to be folded in half.
[0041] (2) When the conveyor 4 is started, the cylinder 304 is started. The cylinder 304 drives the interception seat 305 to move downward through the output shaft. The interception seat 305 drives the limit block 303 to move downward together through the limit rod 301. At the same time, the rubber plate 306 moves downward together with the interception seat 305. When the limit block 303 slides to the lowest side of the limit groove, the cylinder 304 is closed. At this time, the rubber plate 306 fits with the conveyor belt and cooperates with the interception seat 305 to block the movement of the medical bags, so that the medical bags are stacked together. When the support plate 207 rises to a certain height and then falls again to fit with the conveyor belt, The cylinder 304 is started again, driving the interception seat 305 to move upward together to release the interception of the stacked medical bags so that they are transported to the left along with the conveying device 4, and after they are free from the interception, the interception seat 305 is moved down again to intercept the subsequent medical bags. The shielding mechanism 3 blocks the medical bags through the cooperation of the limit rod 301, the fixed box 302, the limit block 303, the interception seat 305 and the rubber plate 306, so that the medical bags can be stacked together, and the interception is released when a certain number of medical bags are stacked, so that a certain number of medical bags can be stacked into a group for subsequent packaging and processing.
