Description

Technical Field

[0001] This utility model belongs to the field of sterile paper-plastic packaging bag production technology, and in particular relates to a cutting device for the production of sterile paper-plastic packaging bags. Background Technology

[0002] Sterilized paper-plastic bags are used for packaging medical devices. They allow for sterilization, aseptic handling (such as clean opening), provide acceptable microbial barrier properties, protect the product before and after sterilization, and maintain a sterile internal environment for a certain period (the stated expiration date) after sterilization. During packaging, the medical device is first placed into the bag and sealed. The bag then undergoes sterilization using a semi-permeable process where sterilizing agents pass through but bacteria cannot.

[0003] The problem with existing technology is that traditional methods require manual control of the sterilized paper-plastic packaging bags to be positioned appropriately under the blade when cutting them. This can be very busy for workers when the workload is large, and the method can easily result in different sizes of the sterilized paper-plastic packaging bags being cut. Therefore, we propose a cutting device for the production of sterilized paper-plastic packaging bags. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for the production of sterilized paper-plastic packaging bags, so as to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a cutting device for the production of sterile paper-plastic packaging bags includes a base plate, a support platform fixedly connected to the middle of the upper surface of the base plate, two sets of support plates fixedly connected to the middle of the upper surface of the support platform, and conveying components arranged on both sides of the upper surface of the support platform. The conveying components are used to convey the sterile paper-plastic packaging bags to be cut. A fixing frame is fixedly connected to the middle of one side of the upper surface of the base plate, and a cylinder is fixedly connected to the lower surface of the fixing frame. A blade is fixedly connected to the piston end of the cylinder.

[0006] As a preferred embodiment of the present invention, the conveying assembly includes a mounting shell, two sets of mounting shells are respectively fixedly connected to both sides of the upper surface of the support platform, and a sliding rod is fixedly connected between both sides of the inner wall of the two sets of mounting shells.

[0007] As a preferred embodiment of this utility model, both sets of sliding rods are movably connected to a movable shell, and both sides of the upper end of the movable shell are fixedly connected to a fixing plate.

[0008] As a preferred embodiment of this utility model, each of the two sets of fixed plates is movably connected to two sets of pull rods, and each of the two sets of pull rods is fixedly connected to a spring between itself and the fixed plate. Each of the two sets of pull rods is fixedly connected to a clamping pad at one end.

[0009] As a preferred embodiment of this utility model, connecting plates are fixedly connected to both sides of the surface of the movable shell, and mounting plates are fixedly connected to both sides of one end of the upper surface of the bottom plate. A tension spring is fixedly connected between the two sets of mounting plates and connecting plates.

[0010] In a preferred embodiment of this invention, a connecting rod is fixedly connected to the upper surface of one set of the fixing plates, and a fixing rod is fixedly connected to one end of the upper surface of the base plate.

[0011] In a preferred embodiment of this utility model, a motor is fixedly connected to one corner of the upper surface of the base plate, and a take-up rod is fixedly connected to the output end of the motor. A pull strap is provided between the take-up rod, the fixed rod, and the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the design of a base plate, support platform, conveying assembly, fixing frame, cylinder, blade and support plate, fixes the sterilized paper-plastic packaging bag inside the conveying assembly and conveys it back and forth during use. After being conveyed to the appropriate position, the cylinder is activated to drive the blade to descend, so that the cylinder cuts the sterilized paper-plastic packaging bag, thus saving the trouble of manual cutting for a long time.

[0014] 2. This utility model, through the design of a mounting shell, sliding rod, movable shell, fixing plate, pull rod, spring, and clamping pad, allows the sterilized paper-plastic packaging bag to be placed on the upper end of the movable shell. The spring will push the pull rod to clamp and fix the sterilized paper-plastic packaging bag. The movable shell can slide on the surface of the sliding rod inside the mounting shell, thus facilitating the movement of the sterilized paper-plastic packaging bag and clamping and fixing it.

[0015] 3. This utility model, through the design of a connecting plate, tension spring, mounting plate, connecting rod, pull strap, fixing rod, take-up rod, and motor, allows the motor to rotate when the stop bar starts the motor. During the rotation, the take-up rod collects the pull strap on the surface of the connecting rod and fixing rod, thereby moving the movable shell. When the motor rotates in the reverse direction, it releases the collected pull strap, causing the tension spring to move the movable shell in the opposite direction. This achieves the effect of automatically conveying sterilized paper-plastic packaging bags back and forth, facilitating cutting. Attached Figure Description

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 3 As shown in the figure, the present invention provides a cutting device for producing sterile paper-plastic packaging bags, including a base plate 1, a support platform 2 fixedly connected to the middle of the upper surface of the base plate 1, two sets of support plates 7 fixedly connected to the middle of the upper surface of the support platform 2, and conveying components 3 jointly provided on both sides of the upper surface of the support platform 2. The conveying components 3 are used to convey the sterile paper-plastic packaging bags that need to be cut. A fixing frame 4 is fixedly connected to the middle of one side of the upper surface of the base plate 1, a cylinder 5 is fixedly connected to the lower surface of the fixing frame 4, and a blade 6 is fixedly connected to the piston end of the cylinder 5.

[0023] The above solution, through the design of base plate 1, support platform 2, conveying component 3, fixing frame 4, cylinder 5, blade 6 and support plate 7, fixes the sterilized paper-plastic packaging bag inside the conveying component 3 and conveys it back and forth. After being conveyed to the appropriate position, the cylinder 5 is activated to drive the blade 6 to descend, so that the cylinder 5 cuts the sterilized paper-plastic packaging bag, thus saving the trouble of manual cutting for a long time.

[0024] refer to Figure 2 and Figure 3 The conveying assembly 3 includes a mounting shell 301. Two sets of mounting shells 301 are fixedly connected to both sides of the upper surface of the support platform 2. A slide rod 302 is fixedly connected between the two sides of the inner wall of the two sets of mounting shells 301. A movable shell 303 is movably connected between the two sets of slide rods 302. A fixing plate 304 is fixedly connected to both sides of the upper end of the movable shell 303. Two sets of pull rods 305 are movably connected inside the two sets of fixing plates 304. A spring 306 is fixedly connected between the two sets of pull rods 305 and the fixing plate 304. A clamping pad 307 is fixedly connected to one end of the two sets of pull rods 305.

[0025] The above solution, through the design of mounting shell 301, sliding rod 302, movable shell 303, fixing plate 304, pull rod 305, spring 306 and clamping pad 307, when the sterilized paper-plastic packaging bag is placed on the upper end of the movable shell 303, the spring 306 will push the pull rod 305 to drive the clamping pad 307 to clamp and fix the sterilized paper-plastic packaging bag. In addition, the movable shell 303 can slide on the surface of the sliding rod 302 inside the mounting shell 301, which achieves the effect of facilitating the movement of the sterilized paper-plastic packaging bag and clamping and fixing the sterilized paper-plastic packaging bag.

[0026] refer to Figure 2 Both sides of the movable shell 303 are fixedly connected to connecting plates 308. Both sides of the upper surface of the base plate 1 are fixedly connected to mounting plates 310. Both sets of mounting plates 310 and connecting plates 308 are fixedly connected to tension springs 309. One set of fixing plates 304 is fixedly connected to a connecting rod 311 on its upper surface. One end of the upper surface of the base plate 1 is fixedly connected to a fixing rod 313. A motor 315 is fixedly connected to a corner of the upper surface of the base plate 1. A take-up rod 314 is fixedly connected to the output end of the motor 315. A pull strap 312 is provided between the take-up rod 314, the fixing rod 313 and the connecting rod 311.

[0027] The above solution employs a design incorporating a connecting plate 308, a tension spring 309, a mounting plate 310, a connecting rod 311, a pull strap 312, a fixing rod 313, a take-up rod 314, and a motor 315. When the stop lever starts the motor 315, the motor 315 drives the take-up rod 314 to rotate. During this rotation, the take-up rod 314 collects the pull straps 312 from the surfaces of the connecting rod 311 and the fixing rod 313, thereby moving the movable shell 303. When the motor 315 rotates in the opposite direction, it releases the collected pull straps 312, causing the tension spring 309 to drive the movable shell 303 to move in the opposite direction. This achieves the effect of facilitating the automatic back-and-forth transport of sterilized paper-plastic packaging bags and making cutting easier.

[0028] The working principle of this utility model:

[0029] In use, when the sterilized paper-plastic packaging bag is placed on the upper end of the movable shell 303, the spring 306 will push the pull rod 305 to drive the clamping pad 307 to clamp and fix the sterilized paper-plastic packaging bag. The movable shell 303 can slide on the surface of the slide rod 302 inside the mounting shell 301, which facilitates the movement of the sterilized paper-plastic packaging bag and the clamping and fixing of the sterilized paper-plastic packaging bag. When the stop rod starts the motor 315, the motor 315 will drive the take-up rod 314 to rotate. During the rotation, the take-up rod 314 will collect the pull strip 312 on the surface of the connecting rod 311 and the fixing rod 313, thereby driving the movable shell 303 to move. When the motor 315 rotates in the opposite direction, it will release the collected pull strip 312, thereby causing the tension spring 309 to drive the movable shell 303 to move in the opposite direction, which facilitates the automatic back-and-forth conveying of the sterilized paper-plastic packaging bag and makes it convenient for cutting.

[0030] In summary, this cutting device for producing sterile paper-plastic packaging bags, through its structure of conveying component 3, mounting shell 301, slide bar 302, moving shell 303, fixing plate 304, pull rod 305, spring 306, clamping pad 307, connecting plate 308, tension spring 309, mounting plate 310, connecting rod 311, pull belt 312, fixing rod 313, take-up rod 314, and motor 315, solves the problem that traditional methods require manual control of the sterile paper-plastic packaging bags to be positioned appropriately under the blade during cutting. This is problematic because it can be very busy for workers when the workload is large, and it can also lead to inconsistencies in the size of the cut sterile paper-plastic packaging bags.
