Abstract
The utility model discloses a rosin injection pen used for a solder wire extruding machine. According to the key point of the technical scheme, the rosin injection pen comprises a pipe body with an injection cavity and an injection head provided with a hole cavity, wherein the pipe body is fixedly connected with the injection head; the hole cavity of the injection head and the injection cavity are communicated; a one-way piece group capable of being opened or closed is fixedly arranged at the other end, opposite to the pipe body, of the injection head; the one-way piece group comprises a plurality of one-way pieces annularly distributed around the injection head; the other end, opposite to the pipe body, of each one-way piece forms an injection end; when being closed, the one-way pieces adopt an enclosed conical structure; when liquid rosin stored in the injection cavity of the pipe body is conveyed into the hole cavity of the injection head and slowly conveyed to the one-way piece group, the one-way pieces are opened under stress, therefore, the liquid rosin enters the hole cavity of the solder wire; as the one-way piece group is in a closed state at the beginning and the air cannot enter, the possibility that air enters the rosin liquid is avoided from the source.
Description
Technical field
The utility model belongs to liquid rosin conveying technology field, is specifically related to a kind of rosin injection pen for soldering tin wire extruder.
Background technology
Soldering tin wire extruder, for tin post is squeezed into hollow solder stick, is injected to rosin based scaling powder in the vestibule of solder stick simultaneously, in the time of injection rosin scaling powder, need to use rosin injection pen.Traditional rosin injection pen has the following disadvantages: air easily enters from the injection port of rosin injection pen, and this air bubble finally can enter in the vestibule of solder stick, causes the phenomenon that in solder stick, rosin line interrupts, and affects product quality.
For above-mentioned weak point, those skilled in the art have carried out relevant improvement.Application number is that 201120031563 Chinese patent discloses a kind of rosin injection pen for soldering tin wire extruder, it comprises and is provided with the tube body of injecting cavity and the tapered portion being connected with tube body, on described tube body periphery wall along apart from tapered portion from being closely provided with successively location division, the first external screw thread district, the fastening boss of hexagonal, the second external screw thread district to direction far away; Described tapered portion outboard end end face is sealing surface, and sealing face centre is provided with along the tubulose injection head of tube body central axial direction projection, and the vestibule of injection head is communicated with injecting cavity.
Although this kind of structure, owing to having sealing surface, when use, is against sealing face on the injection surface that is injected container, thereby effectively prevent that air from entering in the vestibule of rosin liquid and solder stick, avoid the phenomenon that occurs that in solder stick, rosin line interrupts; But because its injection port position is always in open condition, more or less still having some air enters via injection port, be difficult to cause this air bubble finally to enter in the vestibule of solder stick with avoiding, cause the phenomenon that in solder stick, rosin line interrupts, affect product quality.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of and effectively prevents that air from entering the rosin injection pen for soldering tin wire extruder in rosin liquid.
For achieving the above object, the utility model provides following technical scheme: a kind of rosin injection pen for soldering tin wire extruder, comprise and be provided with the tube body of injecting cavity and the injection head being connected with vestibule, tube body is fixedly connected with injection head, and the vestibule of injection head is communicated with injecting cavity, the other end of the relative tube body of described injection head is fixed with expansible or unidirectional closed group, described unidirectional group comprises some unidirectional of distributing ringwise around injection head, described each unidirectional is all sector structure setting, unidirectional one end is fixedly connected with formation stiff end with injection head, the other end forms free end, between stiff end and free end, form main paragraph, each unidirectional two the unidirectional stack of mutually conflicting in main paragraph place being all adjacent when closed, the position of every two unidirectional adjacent stack of mutually conflicting is respectively equipped with the sealing guide rail and the possum belly that are tightly connected, each the unidirectional mutual seamless formula of free end when closed conflicted and connected.
By adopting technique scheme, in the time that the liquid rosin in the injecting cavity that is stored in tube body is delivered to the vestibule of injection head, liquid rosin is slowly delivered to unidirectional group position, unidirectional stressed opening, thereby make liquid rosin enter the vestibule of solder stick, due at the beginning, unidirectional group is in closure state, air has no way of entering, and enters the possibility in rosin liquid so stopped air from source.
The utility model is further set to: described tube body and the junction of injection head are provided with location convex shoulder, and location convex shoulder is placed in the outer surface of tube body.
The utility model is further set to: described location convex shoulder is circulus.
By adopting technique scheme, when use, this location convex shoulder is against on the injection surface that is injected container, further effectively prevent that air from entering in the vestibule of rosin liquid and solder stick, avoid the phenomenon that occurs that in solder stick, rosin line interrupts.
The utility model is further set to: described tube body and injection head removably connect.
The utility model is further set to: described tube body is connected with injection head spiral.
By adopting technique scheme, when unidirectional on injection head open performance or closed performance when reducing or damaging, can only need to change injection head, without discarded whole injection head, economize on resources.

Detailed description of the invention
Referring to figs. 1 through Fig. 3, the utility model is described further for the rosin injection pen embodiment of soldering tin wire extruder.
A kind of rosin injection pen for soldering tin wire extruder, comprise and be provided with the tube body 1 of injecting cavity 11 and the injection head 2 being connected with vestibule 21, tube body 1 is fixedly connected with injection head 2, and the vestibule 21 of injection head 2 is communicated with injecting cavity 11, the other end of described injection head 2 relative tube bodies 1 is fixed with expansible or unidirectional closed group, described unidirectional group comprises some unidirectional 3 of distributing ringwise around injection head 2, described each unidirectional 3 is all sector structure setting, unidirectional 3 one end are fixedly connected with injection head 2 and form stiff end 31, the other end forms free end 33, between stiff end 31 and free end 33, form main paragraph 32, two unidirectional 3 stack of mutually conflicting in main paragraph 32 places being all adjacent when each unidirectional 3 closure, the position of every two unidirectional 3 adjacent stack of mutually conflicting is respectively equipped with the sealing guide rail 34 and the possum belly 35 that are tightly connected, each the unidirectional mutual seamless formula of free end 33 when closed conflicted and connected (seamless formula is herein conflicted to connect and referred to that sealing guide rail 34 is completely closely embedded in possum belly 35).
