Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sterilization paper plastic bag, concretely to a medical sterilization paper plastic bag production facility. BACKGROUND

[0002] Sterilization paper plastic bag is a kind of packaging material used in medical and laboratory environment, mainly used for sterilization treatment to medical instruments, tools and equipment. It combines the advantages of paper and plastic, with good air permeability and waterproofness, suitable for packaging and storage in the sterilization process.

[0003] At present, in the production process of sterilization paper plastic bag, the uneven part of its two side edges needs to be cut off, so that the remaining part reaches the size required by production, but the cut-off part directly falls to the two sides of the equipment, which makes the later cleaning work more complex and time-consuming, and the cut-off part may enter the interior or mechanical components of the equipment, causing equipment failure or damage, affecting production efficiency and product quality. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a medical sterilization paper plastic bag production facility to solve the problems raised in the above background.

[0005] To achieve the above object, the technical scheme of the utility model is as follows.

[0006] A medical sterilization paper plastic bag production facility, including workbench, the one side of workbench upper surface is provided with vertical board, the outer surface of vertical board is rotatably installed with tensioning roller, first winding roller, second winding roller and cutting roller respectively, the outer surface of vertical board is rotatably installed with press roller on the two sides of cutting roller. Transmission is provided with driving mechanism between the end of first winding roller and second winding roller, the outer surface of cutting roller is provided with two cutting knives, the inside of cutting roller is provided with adjusting mechanism that can adjust the distance between two cutting knives.

[0007] Therefore, the paper plastic bag is pressed on the upper surface of the workbench by the two press rollers, so that the cutting knife can be rotated during winding by the first winding roller, and the purpose of cutting the two side edges is achieved, and the cut-off part can be wound on the outer surface of the second winding roller. The driving mechanism can drive the first winding roller and the second winding roller to rotate synchronously, so that the paper plastic bag and the edge part are wound together, thereby avoiding the cut-off part falling directly to the two sides of the equipment, making the later cleaning work more complex and time-consuming, and causing equipment failure or damage, affecting production efficiency and product quality. The adjusting mechanism can adjust the distance between the two cutting knives, so that the paper plastic bag of different sizes can be produced conveniently, and the flexibility is strong.

[0008] Furthermore, the driving mechanism includes a motor installed on the outer surface of the vertical plate, a driving gear is installed at the end of the motor output shaft, a driven gear is installed at the end of the first winding roller, and the driven gear is meshed and connected with the driving gear, and a pulley group is arranged between the ends of the first winding roller and the second winding roller.

[0009] When the motor is started, its output shaft drives the driving gear to rotate. Since the driving gear and the driven gear are engaged with each other, the first winding roller can be driven to rotate to rewind the paper-plastic bag. Moreover, through the transmission action of the pulley group, the second winding roller can be driven to rotate synchronously, so that the cut edge part can be rewound.

[0010] Furthermore, the adjustment mechanism includes a first threaded rod having a pair of reverse threads rotatably mounted inside the cutting roller, nuts being mounted on both reverse threads of the first threaded rod, through grooves being provided on both sides of the outer surface of the cutting roller along its length direction, connecting rods being mounted on the outer surfaces of both sides of the nut, and the ends of the connecting rods passing through the through grooves are connected to the cutting blades.

[0011] When the first threaded rod is rotated, the two nuts can be driven to move inward or outward at the same time through the setting of the reverse thread on its surface. Therefore, the two cutting knives can be driven to move through the connecting action of the connecting rod, thereby achieving the purpose of adjusting the distance between the two cutting knives. The operation is simple and easy to use.

[0012] Furthermore, a groove is provided on one side of the upper surface of the workbench, a lifting plate is provided inside the groove, and the vertical plate is installed on the upper surface of the lifting plate. The lower surface of the lifting plate is rotatably connected to a second threaded rod, and the end of the second threaded rod passes through the bottom of the workbench and is threadedly connected to it. Limit rods are connected on both sides of the lower surface of the lifting plate, and the ends of the limit rods pass through the bottom of the workbench.

[0013] Since the limiting rod limits the lifting plate, when the second threaded rod is rotated, the lifting plate and the vertical plate can be driven to rise and fall vertically, and the pressing roller and the cutting knife can be driven to rise and fall. When placing paper-plastic bags, the pressing roller and the cutting knife can be raised first, leaving a certain distance between their bottom and the workbench. After the paper-plastic bags are placed, the pressing roller and the cutting knife can be lowered and pressed on the paper-plastic bags. This makes it easy to place the paper-plastic bags and improves production efficiency.

[0014] Furthermore, the end of the first threaded rod passes through the outside of the cutting roller and is installed with a knob.

[0015] The setting of the knob makes it easy to rotate the first threaded rod.

[0016] Furthermore, a U-shaped block is installed on the outer surface of the cutting roller, a bolt is passed through the interior of the U-shaped block and is threadedly connected, and a pressure block is installed on the end of the bolt.

[0017] In order to prevent the first threaded rod from rotating during the rotating process of the cutting roller and causing the cutting knife to be displaced, the bolt can be screwed to press the pressing block against the outer surface of the knob, so that the first threaded rod can be fixed to avoid rotating, and the product precision is ensured.

[0018] Further, the support columns are installed at the four corners of the lower surface of the workbench, and the bottom of each support column is provided with an anti-skid pad.

[0019] Through the support columns and the anti-skid pads, the bottom of the workbench can be supported to improve the stability.

[0020] Further, the bottom of the second threaded rod is provided with a hand wheel, and the outer surface of the hand wheel is provided with a rubber pad.

[0021] Through the hand wheel, the second threaded rod can be rotated conveniently, and the hand slipping during the rotating process is reduced. BRIEF DESCRIPTION OF DRAWINGS
