[0035] As shown in the figure, Figs. 1 to 6 The embodiment provides a bottle embryo automatic circulating feeding mechanism, which comprises a circulating conveying belt 1, a heat dissipation assembly 2 and a tail shearing assembly 3 are sequentially arranged above the circulating conveying belt 1, a plurality of bottle embryo jigs 4 are arranged on the circulating conveying belt 1,

[0036] The bottle embryo jig 4 comprises a jig base 401, a limiting lug 402 is arranged at the top center of the jig base 401, and a bottle embryo 5 is vertically sleeved outside the limiting lug 402.

[0037] In actual use,

[0038] I. The bottle preform 5 made by injection molding machine can be placed into the bottle preform fixture 4 upstream of the heat dissipation assembly 2 by a mechanical arm (not shown in the figure) on the side of the circulating conveyor belt 1. In this embodiment, the front of the heat dissipation assembly 2 is provided with a limiting guide groove 6 to guide the bottle preform fixture 4, and the bottle preform fixture 4 is fixed by the telescopic stop lever 603, so that the bottle preform fixture 4 can be accurately positioned to the discharge position of the mechanical arm, and the automatic feeding of the bottle preform 5 is quickly completed.

[0039] II. Subsequently, the bottle preform 5 passes through the heat dissipation assembly 2 and the tail cutting assembly 3 in turn, and the excess part of the tail of the bottle preform 5 is first cooled and shaped by blowing, and then the excess part of the tail of the bottle preform 5 is cut off by the tail cutting assembly 3.

[0040] III. The bottle preform 5 sent out of the tail cutting assembly 3 can be taken out by another mechanical arm to the next device such as a bottle blowing machine for subsequent processing, and the empty bottle preform fixture 4 is transported back to the upstream of the heat dissipation assembly 2 by the circulating conveyor belt 1 to wait for the placement of a new bottle preform 5.

[0041] The jig base 401 is cylindrical, and the limiting protrusion 402 is conical. The cylindrical jig base 401 has high stability and firm support when placed, and can avoid tilting of the bottle preform 5 when placing the bottle preform 5. The conical limiting protrusion 402 can smoothly and quickly penetrate into the inverted bottle preform 5, clamp the opening of the bottle preform 5, and play a positioning role.

[0042] The circulating conveyor belt 1 includes an upstream conveying belt 101 and a reset conveying belt 102 arranged adjacent to each other. The upstream conveying belt 101 and the reset conveying belt 102 have the same length and opposite directions. The upstream conveying belt 101 and the reset conveying belt 102 are both provided with a jig transplanting assembly at both ends. The design of the double linear conveying belt cooperating with the jig transplanting assembly has a compact volume, which can reduce the occupied space of the equipment.

[0043] The jig transplanting assembly includes a jig clamping seat 103, which is slidingly connected to a translation sliding table 104. The bottle preform fixture 4 transported to the end will be automatically clamped into the jig clamping seat 103, and then the translation sliding table 104 starts to push the jig clamping seat 103 together with the bottle preform fixture 4 to the conveying belt in the opposite direction, completing the change of direction of the jig.

[0044] The telescopic push rod 105 is slidingly sleeved on the translation sliding table 104, and the jig clamping seat 103 is installed at the front end of the telescopic push rod 105. Since the jig clamping seat 103 needs to be reset to clamp a new bottle preform fixture 4 after pushing the bottle preform fixture 4 to another conveying belt, and the jig clamping seat 103 is prone to collide with the bottle preform fixture 4 waiting for change of direction on the conveying belt during the resetting process, the telescopic push rod 105 is provided to retract the jig clamping seat 103 backward during the resetting process of the jig clamping seat 103 to avoid collision.

[0045] The heat dissipation assembly 2 comprises a vertically downward heat dissipation fan 201, which is installed at the inner top of a heat dissipation sleeve 202. The air cooling mechanism using the heat dissipation fan 201 to blow air is simple and efficient, and the heat dissipation sleeve 202 can constrain the airflow blown by the heat dissipation fan 201, so as to align the excess part of the tail of the bottle preform 5 and increase the air flow rate.

[0046] The tail cutting assembly 3 comprises left and right parallel rotary blades 301, which are installed on a lifting seat 302. The inner side portions of the left and right parallel rotary blades 301 are stacked up and down, and when the excess part of the tail of the bottle preform 5 passes between the two rotary blades 301, the excess part of the tail of the bottle preform 5 is cut off to form a horizontal cut.

[0047] A waste material through slot 7 is arranged through the circulating conveying belt 1 at the rear end of the tail cutting assembly 3. The cut-off waste material can fall out through the waste material through slot 7, which is convenient for the workers to collect and avoids the waste material from piling up on the conveying belt to hinder the forward movement of the bottle preform jig 4.

[0048] The front ends of the heat dissipation assembly 2 and the tail cutting assembly 3 are provided with limiting guide grooves 6, and the widths of the limiting guide grooves 6 are equal to the width of the bottle preform jig 4. Since the bottle preform jig 4 is not fixed on the conveying belt, the limiting guide grooves 6 are arranged to guide the bottle preform jig 4 to align the working positions of the heat dissipation assembly 2 and the tail cutting assembly 3. The number of the limiting guide grooves 6 can be arranged according to the equipment specifications and the production scale, for example, two limiting guide grooves 6 are arranged side by side in the embodiment.

[0049] One side of the limiting guide groove 6 is provided with an adjusting baffle 601, and one end of the adjusting baffle 601 is slidably sleeved in a width adjusting sliding groove 602. By sliding the adjusting baffle 601 in the width adjusting sliding groove 602, the width of the limiting guide groove 6 can be adjusted according to the bottle preform jig 4 of different sizes.

[0050] The above is a further detailed description of the present application in combination with the specific preferred embodiments, and the specific implementation of the present application cannot be limited to these descriptions. Any changes and modifications made within the scope of the present application should still be included in the scope of the present application.
