Description

Technical Field

[0001] The utility model relates to the technical field related to bottle blowing machines, in particular to a lotus head device. Background Art

[0002] At present, most of the blow molding production equipment uses manual operation to insert and unload the preforms during production, and some automated blow molding equipment uses translation molds. Therefore, the production efficiency is low and it is easy to contaminate the produced bottles. In the field of mechanical processing and production, lotus heads are often used. A lotus head with good quality and easy installation will greatly improve the production efficiency. However, we found that the existing conveyor chains are connected to the conveyor chain of the blow molding machine by a separate lotus head device. Each lotus head device will bear tension. The conveyor chain is generally longer, and generally 100 lotus head devices are invested to form a conveyor chain. Therefore, the overall conveyor chain is heavier, and each lotus head device will bear a relatively large tensile stress. The conveyor chain is always running, so the lotus head device will always be under tension.

[0003] The production efficiency of a single blow-molded preform is not high, and the pulling of the lotus head device alone will also cause its deformation due to uneven force. The existing rotating sleeve assembly, patent number CN202320913849.2, includes a pair of symmetrically distributed rotating sleeves, the pair of rotating sleeves are hinged, the rotating sleeves are provided with plug-in through holes, the hole walls of the plug-in through holes are radially provided with hinge holes, a pin is inserted between the rotating sleeves, the pin passes through the opposite side wall of the rotating sleeve, a pair of rotating sleeves are rotatably connected through the pin passing through the hinge hole, at least one rotating sleeve is equipped with a single-row angular contact ball bearing, the single-row angular contact ball bearing is coaxially arranged with the hinge hole, the hinge hole in one rotating sleeve extends outward from the edge and is recessed to form a limit hole, and the single-row angular contact ball bearing is arranged on the limit hole through the pin. The bottle embryo holder (lotus head device) is connected to the bottle embryo holder (lotus head device) in an embracing form. The use of 7075 aluminum alloy can reduce its weight, reduce the pulling force required during operation, and reduce the occurrence of deformation.

[0004] Therefore, in order to improve the overall efficiency of the bottle blowing machine and minimize the error, a lotus head device made based on the above-mentioned rotating sleeve assembly is needed. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0025] like Figure 1-3As shown, in this embodiment, a lotus head device is provided, including a pair of preform holders, a connecting seat 3 is sleeved between the preform holders, and both side walls of the connecting seat 3 are symmetrically extended outward to be provided with a pair of collars, and the connecting seat 3 is sleeved with the preform holder through the collars, and the preform holder includes a flange-type quick-change sleeve 2, and the flange-type quick-change sleeve 2 is sleeved with a rotating sleeve assembly 4 and passes through the connecting seat 3, and the flange-type quick-change sleeve 2 can withstand the traction force of the rotating sleeve assembly 4, and at the same time exert traction force on the connecting seat 3 to drive the entire lotus head device to move, and a threaded hole is provided on the surface of the middle part of the connecting seat 3 for convenient installation of a pair of bearings.

[0026] In this embodiment, the preform holder also includes an aluminum sleeve 1, which is sleeved on the flange-type quick-change sleeve 2. A pair of annular grooves are provided at one end of the flange-type quick-change sleeve 2 after passing through the connecting seat 3. The annular grooves are provided with elastic retaining rings 7. The elastic retaining rings 7 are buckled on the flange-type quick-change sleeve 2 through the above-mentioned annular grooves. The elastic retaining rings 7 are arranged on the top and bottom side walls of the aluminum sleeve 1 to limit the position of the aluminum sleeve 1 on the flange-type quick-change sleeve 2.

[0027] In this embodiment, a pair of preform holders include an upper sprocket shaft 10 and a lower sprocket shaft 11 arranged adjacent to each other. Regardless of the upper sprocket shaft 10 or the lower sprocket shaft 11, the sprocket shaft is a component in one of the preform holders. The difference between the upper sprocket shaft 10 and the lower sprocket shaft 11 is that the sprockets are arranged in different places. When any one of the two is displaced, the respective sprockets will be collinear and meshed. That is, in the working state, when one of the preform holders rotates, the other preform holder will also rotate. The top end of the upper sprocket shaft 10 is integrally provided with a first sprocket 5, and a first disc is provided below the first sprocket 5. The top end of the lower sprocket shaft 11 is integrally provided with a second disc, and a second sprocket 6 is provided below the second disc.

[0028] In this embodiment, the upper sprocket shaft 10 and the lower sprocket shaft 11 respectively penetrate their corresponding flange quick-change sleeves 2 and are slidingly connected to their corresponding flange quick-change sleeves 2; under normal use, since the sprocket shaft is solid and has a high rigidity, and the sprocket shaft and the flange quick-change sleeve 2 are adapted to be assembled together, when the flange quick-change sleeve 2 is subjected to compressive stress, it will be distributed to the sprocket shaft to avoid stress deformation.

[0029] In this embodiment, both side walls of the connection seat 3 provided with the collar are inwardly recessed to form arc-shaped concave surfaces. The rotating sleeve assembly 4 needs to swing, and the overall profile of the rotating sleeve assembly 4 is an oblong ellipse in cross section, that is, both sides of the swing are arc-shaped extensions. In order to prevent interference and collision when the rotating sleeve assembly 4 rotates, the arc-shaped concave surface matches the two ends of the rotating sleeve assembly 4.

[0030] In this embodiment, one end of the flange-type quick-change sleeve 2 is integrally provided with a mounting head, and one end of the mounting head extends outwardly to form a mounting platform 12 and is provided with a group of threaded holes. The mounting platform 12 can be used to be threadedly connected with the unloading sleeve through bolts and the above-mentioned threaded holes. The mounting and fixing is also integrally provided with a limited convex edge 9 extending outwardly, and the limited convex edge 9 is located below the mounting platform 12. One side wall of the connecting seat 3 extends outwardly to form an integrally provided limited stop pin 8, and the limited stop pin 8 is used to abut against the limited convex edge 9 to limit the axial rotation of the flange-type quick-change sleeve 2. The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of the description of this specification. For ordinary technicians in this field, several deformations and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
