Description
Technical Field
[0001] The utility model belongs to the technical field of die cutting of die pieces, and particularly relates to a die cutting device for die pieces in the production of medical rubber needle caps. Background Art
[0002] Medical rubber needle caps are an important type of medical consumables, mainly used to protect syringe needles and medical workers, while preventing cross-infection. Medical rubber needle caps are generally made of rubber or silica gel materials, with good elasticity and sealing performance, which can effectively prevent contamination and injury caused by needle exposure. They are mainly used in operations such as injection and blood collection in medical institutions to protect the needles from being contaminated and reduce the risk of injury to medical workers during the operation;
[0003] The rubber needle caps are formed by injection molding. To ensure the single injection volume, a certain number of rubber caps are integrally formed on the die piece, and then the rubber caps are punched out from the die piece through a cutting device to form finished products. The existing method is generally that the die piece and a certain amount of rubber caps are injection molded in the mold, and then manually taken out of the mold and transported to the cutting process. In this process, the steps of taking out the die piece from the mold, batch transporting the die piece, and loading the die piece onto the cutting machine are all manually operated, with low efficiency. Moreover, when cutting, it is necessary to align the rubber caps with the cutting die base, and the manual docking accuracy and efficiency are both low, which in turn affects the production progress of the rubber caps;
[0004] To solve the above problems, a die cutting device for die pieces in the production of medical rubber needle caps is proposed in this application. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a die cutting device for die pieces in the production of medical rubber needle caps, which solves the problems raised in the above background art.
[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0007] The utility model is a die cutting device for die pieces in the production of medical rubber needle caps, including a rotating component that drives the die piece to rotate. An elevating component for driving the die piece to ascend and descend is arranged on the rotating component. A material suction component for sucking the die piece is arranged on the elevating component. It also includes a punching component for cutting the die piece and the rubber caps, and a collecting hopper for collecting the cut rubber caps. The rotating component drives the die piece to be transported from the injection molding station to the cutting station. The elevating component demolds the die piece from the mold and docks it with the cutting station. The punching component separates the die piece and the rubber caps at the cutting station through the cooperation of the rotating component and the elevating component.
[0008] Further, the lifting component includes a lifting seat, a top plate located below the lifting seat, and a bottom plate fixed below the top plate.

[0010] Further, the punching component includes a tool holder located between the top plate and the bottom plate, and a tool seat fixed to the top of the collection hopper. A punching cylinder with its output end fixedly connected to the upper end of the tool holder is fixedly provided at the upper end of the top plate. When the diaphragm is slit, it is clamped between the tool holder and the tool seat by the downward movement of the lifting component.
[0011] Further, a cutting tool is provided at the bottom of the tool holder, and a movable hole for the cutting tool to penetrate and slide is opened in the bottom plate.

[0014] The utility model has the following beneficial effects:
[0015] By cooperating with the rotating component, the lifting component and the material suction component, the lifting component drives the material suction component to contact the diaphragm, the material suction component adsorbs the diaphragm, then the diaphragm is separated from the mold by the lifting component, and finally the diaphragm is aligned in the punching component and slit through the rotating component and the lifting component. The blanking, demoulding, and loading operations can be automated through the controller, effectively improving reliability, precision, efficiency, etc.
[0016] By providing a split tool holder and tool seat, the punching component crushes the rotating component, the lifting component, and the material suction component to rotate. The bottom of the tool seat is connected to the collection hopper. Through the rotation of the rotating component, the diaphragm can be rotated from the mold to above the collection hopper, then the diaphragm is pressed tightly by the lifting component, and finally the diaphragm is slit by the punching cylinder. The collection hopper can directly collect the slit rubber caps automatically.
[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.
[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.
[0028] Please refer to Figures 1-5 As shown in the figure, the utility model relates to a slitting device for medical rubber needle caps production die sheets, which includes a rotating component 1 that drives the die sheet to rotate. There is a lifting component 2 on the rotating component 1 that drives the die sheet to lift. There is a material suction component 3 on the lifting component 2 that sucks the die sheet. It also includes a punching component 4 that slits the die sheet and the rubber cap, and a collecting hopper 5 that collects the slit rubber caps. The rotating component 1 drives the die sheet to be transported from the injection molding station to the slitting station. The lifting component 2 demolds the die sheet from the mold and docks it with the slitting station. The punching component 4 separates the die sheet and the rubber cap at the slitting station through the cooperation of the rotating component 1 and the lifting component 2.
[0029] Among them, the lifting component 2 includes a lifting seat 21, a top plate 22 located below the lifting seat 21, and a bottom plate 23 fixed below the top plate 22. A lifting cylinder 24 that drives the top plate 22 and the bottom plate 23 to lift is fixed at the upper end of the lifting seat 21. The material suction component 3 is installed on the bottom plate 23 and is arranged in multiple groups. In this embodiment, while the top plate 22 is connected to the lifting seat 21 by the lifting cylinder 24, a linear sliding mechanism is also provided to ensure the reliability of lifting.
[0030] Among them, the material suction component 3 includes an avoidance hole 31 opened in the bottom plate 23, an electric cylinder 32 fixedly installed at the upper end of the bottom plate 23, and a suction cup 33 located in the avoidance hole 31 and connected to the output end of the electric cylinder 32. In this embodiment, when not sucking the die sheet, the suction cup 33 is located inside the avoidance hole 31 under the action of the electric cylinder 32. The suction cup 33 can adopt an electric structure or be connected and cooperate with an external air source.
[0031] Among them, the punching component 4 includes a tool holder 41 located between the top plate 22 and the bottom plate 23, and a tool seat 42 fixed on the top of the collecting hopper 5. A punching cylinder 43 with an output end fixedly connected to the upper end of the tool holder 41 is fixedly installed at the upper end of the top plate 22. When the die sheet is slit, it is clamped between the tool holder 41 and the tool seat 42 by the downward movement of the lifting component 2. In this embodiment, the top plate 22 and the bottom plate 23 leave a moving space for the tool holder 41, which is convenient for the tool holder 41 to be loaded on the lifting component 2, so that the die sheet can be directly slit after being taken out, improving the structural cooperation degree.
[0032] Among them, a cutting knife 411 is arranged at the bottom of the tool holder 41, and a moving hole 44 for the cutting knife 411 to penetrate and slide is opened in the bottom plate 23. In this embodiment, the moving hole 44 not only serves as an avoidance for the punching of the cutting knife 411, but also plays a guiding and stabilizing role for it, enabling it to better integrate into the lifting component 2.
[0033] Among them, a die 421 for inserting a rubber cap and a cutting knife 411 is provided on the tool holder 42. In this embodiment, when the head of the cutting knife 411 is inserted into the die 421, the rubber cap is cut from the diaphragm at this time. The cutting knife 411 continues to move downward, and the rubber cap falls into the collection hopper 5 from below the die 421, realizing automatic collection after cutting.
[0034] Among them, the rotating member 1 includes a turntable 11 rotatably mounted on the base, a motor 12 mounted on the base and driving the turntable 11 to rotate, and a rotating frame 13 fixed on the turntable 11. The lifting seat 21 is fixed on the rotating frame 13. In this embodiment, in order to ensure that the lifting member 2, the material suction member 3, and the tool holder 41 are always used in a horizontal state, the rotating member 1 is an overall strengthened member.
[0035] It can be understood that, first, the cooperation of the set rotating member, lifting member, and material suction member can automatically realize the transfer of the diaphragm from the mold to the tool holder, saving the labor and auxiliary equipment costs of manual transfer. At the same time, it also improves the efficiency, accuracy, and reliability. At the same time, the set punching and cutting member can directly perform the cutting work on the diaphragm after transfer and automatically collect it in the collection hopper, improving the production efficiency of the plastic cap.
[0036] A specific application of this embodiment is as Figures 1-2 shown. The utility model cooperates with a mold for lifting a rubber cap, and the mold is located on the rotation path of the rotating member 1 driving the lifting member 2 and the material suction member 3. When the mold is injection-molded and the diaphragm is cooled, the upper mold of the mold opens upward at this time. The rotating member 1 drives the lifting member 2, the material suction member 3, and the tool holder 41 to rotate to directly above the lower mold. At this time, the lifting member 2 drives the material suction member 3 and the tool holder 41 to move downward, and the bottom of the bottom plate 23 contacts the top of the diaphragm. The electric cylinder 32 drives the suction cup 33 to extend downward and suck the diaphragm. The second lifting member 2 drives the material suction member 3, the tool holder 41, and the diaphragm to move upward, and the diaphragm is demolded on the lower mold base. The rotating member 1 rotates the lifting member 2, the material suction member 3, the tool holder 41, and the diaphragm to directly above the tool holder 42. At this time, the lifting member 2 descends, so that the rubber cap is inserted into the die 421, and the diaphragm is pressed between the tool holder 41 and the tool holder 42. The punching and cutting cylinder 43 pushes the tool holder 41 downward, and the cutting knife 411 cooperates with the die 421 to cut the rubber cap from the diaphragm. The cutting knife 411 enters the die 421, and then the cut rubber cap passes downward through the die 421 and falls into the collection hopper 5. Just place a collection basket at the outlet of the collection hopper 5;
[0037] The suction cup 33 after cutting is still in the adsorption state. The lifting member 2 rises and the rotating member 1 rotates. A basket for recovering the diaphragm is placed on the rotation path of the rotating member 1 driving the lifting member 2. After the rotating member 1 rotates in place, the suction cup 33 is disengaged from adsorption, and the diaphragm falls into the basket;
[0038] After the die piece is taken out of the mold, the mold can continue the injection molding work. At the same time of injection molding, the present utility model transports, cuts, and recycles waste of the die piece, making the production process of the rubber cap more compact and efficient.
