Problems solved by technology

[0004] When one-stage stamping is used, due to the insufficient stamping speed of the cylinder during stamping, it is easy to cause defects such as the filter paper cannot be completely dropped or the filter paper has burrs.
In addition, when a tubular die is used, the knife edge of the tubular die will be dull or curled after long-term use, res

Embodiment 1

[0020] As shown in Figure 1, the filter paper punching device of the automatic infusion set assembly machine is fixed by a support 3, and a paper roll conveying mechanism 2 is fixedly connected to the support 3. A paper punching die 4 is fixed on the bottom of the support 3, and several die holes 10 are arranged on the paper punching die 4, and each die hole 10 is arranged in a row. The paper punching die 4 is provided with a transversely extending paper feed slot 4a for the filter paper belt to pass through, and the paper feed slot 4a separates each die hole 10 into an upper die hole 10a and a lower die hole 10b. The lower die hole 10b has a supporting effect on the filter paper. When the punching rod 5 is inserted into the die hole 10, it can be easily punched down, while the upper die hole 10a has a guiding effect. Above the punching die 4, there is a punching rod 5 arranged vertically in one-to-one correspondence with the die holes 10, and the punching rod 5 is fixed on a ...

Embodiment 2

[0024] As shown in FIG. 2 , the structure and principle of this embodiment are basically the same as those of the first embodiment, except that the length of the punching rod 5 is greater than the distance between the second cylinder 9 and the punching rod guide seat 11 . The punching rod 5 passes through the punching rod guide seat 11 and grows a part, so that the filter paper punched down can be directly sent into products with deep notches such as bottle inserting needles.

Abstract

The invention provides a filter paper punching device of an automatic assembly machine of an infusion device, belongs to the field of mechanical technology, and solves the concave wrinkles and deckle edges phenomena that occur on the filter papers punched by the present filter paper punching device of the automatic assembly machine of the infusion device. The filter paper punching device of the automatic assembly machine of the infusion device comprises a stent, and a paper punching mold is fixed at the stent, and at least a mold hole is opened in the paper punching mold, and a paper punching rod which is arranged in one to one correspondence to the mold hole along the vertical direction is arranged at the upper part of the paper punching mold, and the paper punching rod is fixed at a punching mechanism that is arranged at the stent; the front end of the paper punching rod is provided with a punching plane which is used for punching the filter papers. The filter paper punching device of the automatic assembly machine of the infusion device which uses the secondary punching is fast in speed, big in punching force and can punch and drop off the filter papers easily and completely. The filter paper punching device of the automatic assembly machine of the infusion device, which can be punched down completely and be punched to the installation position correctly, is not prone to be destroyed and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an automatic assembling machine for infusion sets, in particular to a filter paper punching device for the automatic assembling machine for infusion sets. Background technique [0002] Many medical devices in clinical medicine have filters, such as disposable infusion sets, inflatable bags, bottle insertion needles and other components. The disposable infusion set is to introduce the medicinal liquid in the medicinal liquid bottle into the human body. The vast majority of liquid medicine bottles have a rubber stopper. When in use, the connection end on the infusion set needs to be inserted into the stopper. During the insertion process, some small rubber particles will be produced from the stopper. These Small rubber particles will enter the medicinal solution along with the plug-in end of the infusion set. If no filter is set in the infusion set, these small rubber particles m...
