[0023] In order to explain the technical content, structural features, achieved objectives and effects of this application in detail, the technical solutions in the embodiments of this application will be described below in conjunction with the drawings in the embodiments of this application.

[0024] In this application, spatially relative terms such as "under," "beneath," "under," "down," "over," "up," "above," "higher," "side" (e.g., as in "sidewall"), etc., are used to describe the relationship of one element to another (other) element as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, an element described as "under" or "beneath" other elements or features would then be positioned "over" the other elements or features. Thus, the exemplary term "under" can include both above and below orientations. Furthermore, the device can be positioned otherwise (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.

[0025] like Figure 1-4 The present invention provides a cooling conveyor device 00, which can be deployed within a blow molding machine or between the blow molding machine and downstream equipment (such as a deflashing device for removing flash from blow-molded products) to cool blow-molded products while conveying them. Specifically, the cooling conveyor device 100 comprises a support frame 1 and a pair of horizontally arranged cooling conveyor units (not shown). Each cooling conveyor unit includes a conveying mechanism for conveying hollow products, as well as upper and lower cooling mechanisms for cooling. In other embodiments, the cooling conveyor device can also be adaptively configured with one or more cooling conveyor units based on the size of the blow-molded products and the required cooling capacity.

[0026] In the application, the conveying direction of the conveyor belt 22 is defined as the longitudinal direction; Figure 3 The direction perpendicular to the longitudinal direction on the paper is defined as the transverse direction; Figure 2 The direction perpendicular to the longitudinal direction on the paper is defined as the vertical direction.

[0027] The support frame 1 is constructed from multiple longitudinally or vertically extending steel bars. Specifically, it includes several bottom plates 11 at the bottom, several vertically extending support columns 12 fixedly mounted (either directly or via intermediate components) on a conveyor bracket 21 (described below), and a pair of product ribs 13 and a pair of flash ribs 14 fixedly mounted on these support columns 12.

[0028] A pair of product ribs 13 are located on the upper side of the conveyor belt 22 (see below) and are arranged in parallel in the transverse direction. Figure 4 The pair of product sidewalls 13 are respectively adjacent to the lateral edges of the pair of conveyor belts 22. The pair of product sidewalls are used to prevent the blow-molded product from deviating from its trajectory and falling off the cooling conveyor device 100 due to reasons such as mismatch in the conveying speeds of the pair of conveyor belts 22.

[0029] A pair of flash ribs 14 are located above the pair of product ribs 13, and the lateral spacing between the pair of flash ribs 14 is smaller than the lateral spacing between the pair of product ribs 13. The pair of flash ribs 14 are used to limit the flash of the blow-molded product and prevent the flash in the molten state from deforming and adhering to the blow-molded product.

[0030] Each conveying mechanism includes a longitudinally extending conveying bracket 21, a movable conveyor belt 22 mounted on the conveying bracket 21, and a drive assembly 23 for providing moving power to the conveyor belt 22. The conveyor belt 22 is used to carry the molded blow-molded products and transport them to downstream equipment.

[0031] The drive assembly 23 is the power source for the conveyor mechanism and consists of an electric motor (not shown), a speed reducer (not shown), a coupling (not shown), and a drive roller (not shown). The electric motor provides the power, the speed reducer converts the high-speed rotation of the motor into a low-speed, high-torque rotation suitable for the conveyor mechanism, the coupling connects the motor and speed reducer, and the drive roller drives the conveyor belt through friction.

[0032] Furthermore, the conveyor belt 22 of this embodiment is a chain-type conveyor belt, composed of multiple chain plates assembled into a chain-like structure through pins or other connecting means, forming the conveyor belt's load-bearing surface. This chain-type conveyor belt offers advantages such as high load-bearing capacity, long service life, and ease of cleaning and maintenance. Furthermore, due to the presence of gaps between the chain plates, compared to belt-type conveyor belts, this chain-type conveyor belt facilitates the cooling air generated by the lower cooling mechanism to pass through the conveyor belt 22 and cool the blow-molded products.

[0033] The upper cooling mechanism includes an upper cooling fan 31 fixedly mounted on the support frame 1, an upper cooling air duct 32 located above the conveyor belt 22 and extending from the upstream end to the downstream end of the conveyor belt 22, and a steel hose 33 located between the upper cooling fan 31 and the upper cooling air duct 32. The air outlet of the upper cooling fan 31, the steel hose 33, and the upper cooling air duct 32 are fixedly connected in sequence and fluidically communicated.

[0034] A laterally extending fan base 15 is mounted on the support base 1. An upper cooling fan 31 is mounted on this fan base 15 and provides the cooling air flow. The upper cooling air duct 32 has multiple upper cooling air outlets (not shown) facing the conveyor belt 22. These upper cooling air outlets are spaced longitudinally.

[0035] When the cooling conveying device 100 is working, the upper cooling fan 31 starts and draws in cooling air, which flows through the steel hose 33 and the upper cooling air duct 32 in turn, and is finally blown out from the upper cooling air outlet to cool the blow-molded products on the conveyor belt 22.

[0036] In this embodiment, the support frame 1 further includes a plurality of crossbeams 16 located at the top and extending laterally, and the upper cooling air duct 32 is fixedly mounted on the support frame 1 by hoisting.

[0037] Similarly, the lower cooling mechanism includes a lower cooling fan 41 fixedly mounted on the support frame 1 and a lower cooling duct 42 located below the conveyor belt 22 and extending from the upstream end to the downstream end of the conveyor belt 22. The lower cooling fan 41 and the lower cooling duct 42 are in fluid communication and are both fixedly mounted on the base plate 11 of the support frame 1. The lower cooling duct 42 has multiple lower cooling air outlets (not shown) facing the conveyor belt 22, spaced longitudinally.

[0038] When the cooling conveying device 100 is working, the lower cooling fan 41 starts and sucks in cooling air. This cooling air flows through the lower cooling air duct 42 and is finally blown out from the lower cooling air outlet to cool the blow-molded products on the conveyor belt 22.

[0039] The cooling conveyor device 100 provided by this utility model can transport blow-molded products, having been demolded by a blow molding machine, to downstream equipment. During the transport process, cooling air is supplied to the blow-molded products via upper and lower cooling mechanisms, rapidly cooling the blow-molded products. This cooling conveyor device 100 is simple to arrange and does not require additional operating time, thereby improving the efficiency of the blow molding line.

[0040] The above embodiments are intended only to illustrate the technical concepts and features of this application. Their purpose is to enable those familiar with the art to understand the content of this application and implement it accordingly. They are not intended to limit the scope of protection of this application. Any equivalent changes or modifications made in accordance with the spirit of this application shall be included in the scope of protection of this application.
