[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] It should be noted that when a component is referred to as being "fixed on" or "disposed on" another component, it may be directly or indirectly located on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and cannot be understood as limitations on the present technical solution. The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0045] The preform mold is generally composed of a core plate, a separation plate and a cavity plate, wherein the core plate and the separation plate together serve as a movable mold plate, and the cavity plate serves as a fixed mold plate. The movable mold plate is molded together with the fixed mold plate to form one or more mold cavities. The preform manufacturing melt is injected into the mold cavity through the runner under high pressure. The preform manufacturing melt in the mold cavity is formed into a preform by cooling.

[0046] After the preform is formed and the mold is opened, the preform needs to be taken out of the mold by a robot and placed on a conveyor belt to be transported to the next station. Since the placement direction of the conveyor belt is in a different direction from the mold closing direction, in order to save time, the existing robot is usually fixed with a preform removal device and a preform suction device. After the preform is taken away by multiple preform removal cylinders on the preform removal device (by suction), the preform suction device (by suction) receives the preform on the preform removal cylinder and places the preform on the conveyor belt.

[0047] However, after being used for a long time, the sucker in the existing sucking device is prone to long-term wear, which leads to the leakage of suction force of the sucker when it is docked with the sucking tube and fails to suck the bottle blanks. The spring of the sucker is also prone to elastic deformation and loss of resilience after being used for a long time, resulting in the sucker being unable to work normally. In this way, the entire sucking plate and the sucker need to be replaced before they can be used again, which is a great waste of resources.

[0048] For this purpose, see Figure 1 , Figure 5 , Figure 6 and Figure 7 A blank suction device provided in a first aspect of an embodiment of the present application comprises a blank suction plate 1, a blank suction assembly 2 and a suction power source (not shown in the figure), wherein the blank suction assembly 2 comprises a plurality of blank suction devices 21, and the plurality of blank suction devices 21 are all arranged on the blank suction plate 1, and the blank suction device 21 comprises a base 211, a blank suction head 212, a guide rod 213 and an elastic member 214, wherein the base 211 is arranged on the blank suction plate 1, the blank suction head 212 is arranged above the base 211, one end of the guide rod 213 passes through the blank suction head 212 and is connected to the base 211, and one end of the guide rod 213 is away from the base 211 A hexagonal column groove 2131 is provided, the elastic member 214 is sleeved on the guide rod 213 and is located between the base 211 and the blank suction head 212, one end of the elastic member 214 is against the base 211, and the other end is against the blank suction head 212, the elastic force of the elastic member 214 is used to make the blank suction head 212 away from the base 211, the suction power source is arranged on the side of the blank suction plate 1 away from the blank suction assembly 2, the suction power source, the blank suction plate 1 and the blank suction device 21 are connected in sequence, and the bottle blank 8 is sucked into the blank suction head 212 through the guide rod 213 through the suction power source.

[0049] It can be understood that when the blank sucker 21 is required to suck the bottle blank 8 from the blank removal cylinder 9, the suction power source provides suction and sucks the bottle blank 8 through the blank sucker 21. At this time, the bottle blank 8 passes through the guide rod 213 and is sucked into the blank sucking head 212, and the elastic member 214 is in a compressed state; when the blank sucker 21 is required to place the sucked bottle blank 8 on the transmission belt, the suction power source retracts the suction, and the elastic member 214 stretches under its own elastic state to make the blank sucking head 212 move away from the base 211, and the bottle blank 8 is released onto the transmission belt.

In order to prevent the suction board 1 from deforming, the suction board 1 is thickened, and a hollow groove 11 is opened on the suction board 1. Fig.11 The hollowed-out groove 11 is arranged at a position which does not affect the strength and use of the suction board 1 , so that the strength of the suction board 1 can be ensured and the weight of the suction board 1 can be reduced.

For example, assuming that there are four groups of blank taking components, there is one group of blank suction components 2 and three groups of blowing components 3. Among them, the blank suction plate 1 takes blanks from the four groups of blank taking components in turn, and replenishes the idle blank taking components in time to ensure that the four groups of blank taking components can all take the bottle blanks 8, and the blank suction component 2 is connected to one of the four groups of blank taking components in turn to place the bottle blank 8 on the conveyor belt, and the remaining three groups of blank taking components will be connected to the three groups of blowing components 3 to cool the bottle blanks 8 on the blank taking components, so that the bottle blanks 8 sucked away by the blank suction component 2 are finally fully cooled before being placed on the conveyor belt.

[0056] Optional, see Figure 1 and Figure 3 In one embodiment, the end of the blowing pipe 311 away from the blank suction plate 1 passes through the blowing pipe sleeve 312 and is configured to match the conformal structure of the bottle blank 8.

It can be understood that when the blank sucker 21 is required to suck the bottle blank 8 from the blank removal cylinder 9, the suction power source provides suction and sucks the bottle blank 8 through the blank sucker 21. At this time, the bottle blank 8 passes through the guide rod 213 and is sucked into the blank sucking head 212, and the elastic member 214 is in a compressed state; when the blank sucker 21 is required to place the sucked bottle blank 8 on the transmission belt, the suction power source retracts the suction, and the elastic member 214 stretches under its own elastic state to make the blank sucking head 212 move away from the base 211, and the bottle blank 8 is released onto the transmission belt.
