Abstract

The utility model relates to a bottle blank separating device used in two-step manufacture of hollow blow-molded containers. The bottle blank separating device comprises a base, and a separating chain and a reset piece which are arranged on the base. The bottle blank separating device is characterized in that the separating chain at least comprises a straight working section; picks capable of limiting rotary motion are arranged on the separating chain at equal intervals; the reset piece is positioned at one end of the working section of the separating chain; bottle blanks are separated by using the picks arranged at equal intervals on the separating chain performing rectilinear motion, so that intervals meeting the process requirement are formed between the bottle blanks; and the picks are reset by using the reset piece and act on the side walls of the bottle blanks, thereby effectively preventing the phenomena that the inner chambers of the bottle blanks are contaminated and the mouths of the bottle blanks are damaged. Therefore, the automation in bottle blank separating is achieved, the mechanical structure is simplified, the manufacturing cost is lowered, and potential safety hazards in the production process are eliminated.

The specific embodiment

Be further described below in conjunction with Figure of description and the specific embodiment substantive distinguishing features the utility model.

A kind of bottle base as shown in the figure divides apart from device; By base 1, place branch on the base 1 apart from chain 2 and return unit 4; It is characterized in that described branch has line active section always at least apart from chain 2, but described branch apart from the plectrum that is provided with limit rotation 5 of chain 2 equal intervals, described return unit 4 is positioned at the end of described branch apart from chain 2 active sections; Utilization is done straight-line branch and is carried out branch apart from operation apart from the 5 pairs of bottle bases of equidistance plectrum on the chain 2, and utilizes 4 pairs of plectrums 5 of return unit to play reset response; Described plectrum 5 is L-shaped, and the link that said plectrum 5 is positioned at corner region on the chain link 16 of chain 2, is that center do rotate freely motion with pin-and-hole 15 through the pin-and-hole 15 rotating branches that are connected; Described plectrum 5 be positioned at branch apart from the free end in chain 2 outsides for dividing apart from the working end, be positioned at branch and be provided with the limit projection 13 that turns up apart from chain 2 inboard free ends, inboard contiguous pin-and-hole 15 places are provided with in the limit and change projection 14; Said plectrum 5 inboard free end thickness limit the projection 13 that turns up to play the effect that restriction plectrum 5 rotates greater than its working end thickness, have guaranteed the support to plectrum 5; Bottle base can accurately be dialled leave, when the branch of minute accomplishing bottle bases apart from chain 2 after operation, when bottle base is transported to subsequent processing, can plectrum 5 working ends be hit branch apart from chain 2 one sides; Play restriction with changeing projection 14 in the time limit, guaranteed that plectrum 5 can be because of the bottle base collision excessively can't not reset, described return unit 4 is conflicted by the shell that is provided with step-like perforate 6 ﹑ and is formed at spring on the endoporus step surface 7 and the latch 8 that passes shell 6 perforates and conflict on spring 7; Described latch 8 working ends are dome shape, through the position-limiting action of spacing block set 14, plectrum 5 are effectively supported; Bottle base can accurately be dialled divides, when the branch of minute accomplishing bottle bases apart from chain 2 after operation, through the folder blank will divide apart from after bottle base go out minute apart from device along conveying trough 10 translations; When bottle base is moved out of; Bottle base promotes the plectrum 5 in the place ahead, and to make plectrum 5 be the center of circle with the tie point to minute rotating and draw close apart from chain 2, when plectrum 5 with minute when chain 2 motions contact with return unit 4; Because the conflict of spring 7; It is that homing action is carried out in the center of circle that plectrum 5 receives behind the resistance of latch 8 working ends with the fixing point, and when plectrum 5 resets, the limit of plectrum 5 projection 13 that turns up is conflicted when minute on chain, being supported; The working end of latch 8 is stressed; And extrusion spring 7 makes on the latch 8 and moves, and when the distance of 1 of latch 8 working ends and base during greater than plectrum 5 working end thickness, return unit 4 is streaked in the working end of plectrum 5; Described base 1 has at least one section profile corresponding apart from chain 2 active sections with described branch; And be provided with a profile and said base 1 corresponding guide plate 9; 9 on described base 1 and described guide plate are provided with conveying trough 10; Described branch is provided with one lets the bottleneck projecting ring section of bottle base conflict on base 1 and guide plate 9 apart from chain 2 active sections tops through the adjustable limiting plate 11 that is suspended on the base 1 of support; Guide effect through base 1 and guide plate 9 limits the mobile route of bottle base, and conflicting at the lower surface of limiting plate 11 in the top of bottle base, guarantees that bottle base keeps vertical state when being pushed away translation by plectrum 5.
