Description
Technical Field
The utility model relates to a blowing instrument technical field, in particular to dialysis bucket blowing is with blowing needle.
Background
The dialysis bucket is the packing material of hemodialysis concentrate product is exclusively used in, and it forms through the production of blowing process generally, when carrying out the blowing operation to the dialysis bucket, must use and blow the needle device, but because its structural design defect among the original needle device that blows leads to dialysis bucket bung hole inner wall unsmooth, will appear sealed not tight phenomenon when holding the hemodialysis concentrate, in order to solve this problem, the utility model provides a simple structure, high efficiency, novel in design to the uneven blowing machine of solution bung hole inner wall that can be fine blows the needle device.
Disclosure of Invention
The utility model aims at the problem in the background art with not enough, provide a dialysis bucket blowing needle structure for blowing.
The utility model provides a dialysis bucket blowing is with blowing needle, is including blowing the needle, blow the inside through-hole that prolongs its axial direction and extend that is equipped with of needle, blow needle through-hole upper end and be the inlet end, blow needle through-hole lower extreme for giving vent to anger the end, blow the needle upper end and be equipped with and blow the connecting portion that the needle frame is connected, the connecting portion outer wall is equipped with the external screw thread, the connecting portion lower extreme is blown and is equipped with annular sealing rubber ring holding tank on the needle, sealing rubber ring holding tank internal connection has sealing rubber ring, is connected with the incision ring on the needle is blown to sealing rubber ring holding tank lower part, is equipped with annular secondary extrusion portion on the needle is blown to incision ring lower part, is equipped with annular primary extrusion portion on the needle, is equipped with the hemisphere guide portion on the annular primary extrusion portion lower part blows the needle, annular primary extrusion portion diameter is less than annular secondary extrusion portion.
The utility model has the advantages that:
the utility model discloses a special design's blow needle structure, the bung hole mirror surface of the dialysis bucket of producing is level and smooth, when taking up hemodialysis concentrate product, has avoided the not tight phenomenon of product seal, has improved the quality of product greatly.

Fig. 2 is a sectional view of the present invention.
Fig. 3 is a schematic view of the local enlargement at a position of the present invention.
Detailed Description
Referring to fig. 1 to 3, a blowing needle for blow molding of a dialysis barrel comprises a blowing needle, wherein a through hole 1 extending along an axial direction of the blowing needle is formed in the blowing needle, an air inlet end is formed at the upper end of the through hole 1 of the blowing needle, an air outlet end is formed at the lower end of the through hole 1 of the blowing needle, a connecting portion 2 connected with a blowing needle frame is formed at the upper end of the blowing needle, external threads are formed on the outer wall of the connecting portion 2, an annular sealing rubber ring accommodating groove 3 is formed in the blowing needle at the lower end of the connecting portion 2, a sealing rubber ring is connected in the sealing rubber ring accommodating groove 3, a notch ring 4 is connected to the blowing needle at the lower portion of the sealing rubber ring accommodating groove 3, an annular secondary extrusion portion 5 is formed on the blowing needle at the lower portion of the notch ring 4, an annular primary extrusion portion 6 is formed on the blowing needle at the lower portion of the annular secondary extrusion portion 5, and a hemispherical guide portion 7 is formed on the blowing needle at the lower portion of the annular primary extrusion portion 6; the diameter of the annular primary extrusion part 6 is smaller than that of the annular secondary extrusion part 5.
Furthermore, the blow pin through hole 1 is concentrically arranged with the blow pin.
Furthermore, the outer diameter of the annular secondary extrusion part 5 is equal to the inner diameter of the bung.
Furthermore, the outer wall of the blowing needle is coated with an anti-sticking layer.
The utility model discloses a theory of operation and use:
referring to fig. 1 to 3, the blowing pin structure realizes automatic lifting by using a hydraulic device of the device, and realizes primary extrusion and primary cooling processes by using a hemispherical guide part 7 and an annular primary extrusion part 6 at the front end of the blowing pin structure, so that the blowing pin is primarily contacted with the inner wall of the bung for extrusion, cooling and shaping.
And in the continuous falling process, the material contacts the annular secondary extrusion part 5 to realize secondary extrusion cooling of the inner wall of the barrel opening, so that the material can form a super-saturated high-concentration state between the blowing needle and the die 10, the complete shaping and cooling of the inner wall of the barrel opening are realized, and the surface is smooth and flat.
And the material contacts the position of the notch ring 4 in the continuous falling process, the notch ring 4 presses the material between the blowing needle and the mould 10 at high pressure again, presses the material again and cuts the leftover material of the opening of the bucket, and the high-density supersaturation state of the material between the blowing needle and the mould is kept.
The bung hole is through blowing needle structure cooling cycle and mould cooling cycle, realizes the rapid design process, accomplishes whole production use.
