Description

Technical Field

[0001] This utility model relates to the field of preform cooling technology, and more specifically, to a preform adsorption refrigeration device. Background Technology

[0002] A preform is the embryo or prototype of a bottle. It is usually a semi-finished product obtained by processing plastic granules into liquid plastic at high temperature and then transporting it to a preform mold to cool and solidify. The preform plays the role of an intermediate in the bottle processing and is a necessary stage before the molding of plastic bottles, glass bottles and other containers. After PET masterbatch is melted and extruded into preforms in an injection molding machine, there is residual material at the tail. Before entering the next process, the residual material at the tail of the preform needs to be trimmed on a tail trimming machine. When trimming the tail of the preform, the preform must be in a cooled and rigid state. However, since the freshly extruded preform is still hot and in a hot and sticky state, it needs to be cooled.

[0003] A search revealed a bottle preform cooling device disclosed in Chinese Patent Publication No. CN 222271178 U. Although the vertical movement of the lifting plate drives the vertical movement of the fan, thereby adjusting the height of the fan and reducing the labor intensity of the workers, and improving the cooling effect on the bottle preform, the cooling speed of the bottle preform is relatively slow because the airflow generated by the fan is blown onto the bottle preform for cooling, and the airflow is at room temperature, which affects the cooling efficiency of the bottle preform. Based on this, this utility model designs a bottle preform adsorption refrigeration device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a preform adsorption refrigeration device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A preform adsorption refrigeration device includes a base platform, an adsorption refrigeration unit, and heat exchange tubes. A conveying assembly is installed on the base platform. The adsorption refrigeration unit is fixedly mounted above the base platform via a bracket. An electric push rod is fixedly installed inside the bracket. A lifting seat is fixedly installed at the telescopic end of the electric push rod. A blower motor is fixedly installed on the lifting seat. A fan is fixedly connected to the drive shaft of the blower motor. A wind guide shroud is fixedly installed at the bottom of the lifting seat outside the fan. The heat exchange tubes are fixedly installed inside the wind guide shroud and located below the fan. An L-shaped water guide pipe and an L-shaped return water pipe are fixedly connected to both ends of the heat exchange tubes, respectively. A cooling water outlet pipe and a cooling water inlet pipe are fixedly connected to the inlet and outlet ends of the adsorption refrigeration unit, respectively. The cooling water outlet pipe is slidably sleeved outside the upper end of the L-shaped water guide pipe, and the cooling water inlet pipe is slidably sleeved outside the upper end of the L-shaped return water pipe.

[0007] As a preferred embodiment of the present invention, the conveying assembly includes a conveying motor, a conveyor belt, and two rollers. The conveying motor is fixedly installed on the side of the base platform, and the two rollers are rotatably connected to the inner ends of the base platform. The conveyor belt is tumbled between the two rollers, and the end of one roller is fixedly connected to the drive shaft of the conveying motor.

[0008] As a preferred embodiment of this utility model, two guide columns are symmetrically and fixedly connected between the base and the support, and the lifting seat is slidably sleeved on the outside of the guide columns.

[0009] As a preferred embodiment of this utility model, a side seat is fixedly installed on the side of the bracket, and the side seat is fixedly sleeved on the outside of the cooling water outlet pipe and the cooling water inlet pipe.

[0010] As a preferred embodiment of this utility model, the heat exchange tube has a serpentine cross-sectional shape and is a component made of copper.

[0011] As a preferred embodiment of this utility model, two ventilation openings are provided on the inner surface of the base, and the two ventilation openings are symmetrically distributed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes an adsorption chiller to generate cooling water, which enters the heat exchange tube through a cooling water outlet pipe and an L-shaped guide pipe. The water then returns to the adsorption chiller through a cooling water inlet pipe and an L-shaped return pipe. A blower motor drives a fan to rotate, and the ambient temperature airflow generated by the fan exchanges heat with the cooling water flowing in the heat exchange tube, thereby obtaining a low-temperature airflow that is blown onto the preform. This allows for rapid cooling of the preform, improving the cooling efficiency. If the height of the fan needs to be adjusted, an electric push rod drives the lifting seat and the fan to move up and down. The L-shaped guide pipe and the L-shaped return pipe slide along the cooling water outlet pipe and the cooling water inlet pipe, respectively, allowing the fan to be adjusted to the desired height.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, this utility model provides a bottle preform adsorption refrigeration device, including a base platform 1, an adsorption refrigeration unit 2, and a heat exchange tube 3. A conveying assembly is provided on the base platform 1. The adsorption refrigeration unit 2 is fixedly installed above the base platform 1 via a bracket 101. An electric push rod 4 is fixedly installed inside the bracket 101. A lifting seat 5 is fixedly installed at the telescopic end of the electric push rod 4. A blower motor 6 is fixedly installed on the lifting seat 5. A fan 601 is fixedly connected to the drive shaft of the blower motor 6. The bottom end of the lifting seat 5 is fixed outside the fan 601. The air guide shroud 501 is installed, and the heat exchange tube 3 is fixedly installed inside the air guide shroud 501. The heat exchange tube 3 is located below the fan 601. The two ends of the heat exchange tube 3 are respectively fixedly connected to the L-shaped water guide pipe 301 and the L-shaped return water pipe 302. The cooling water inlet and outlet ends of the adsorption chiller 2 are respectively fixedly connected to the cooling water outlet pipe 201 and the cooling water inlet pipe 202. The cooling water outlet pipe 201 is slidably sleeved on the upper outside of the L-shaped water guide pipe 301, and the cooling water inlet pipe 202 is slidably sleeved on the upper outside of the L-shaped return water pipe 302.

[0022] Among them, such as Figure 2As shown, the conveying assembly includes a conveyor motor 102, a conveyor belt 103, and two rollers 104. The conveyor motor 102 is fixedly installed on the side of the base platform 1. The two rollers 104 are rotatably connected to the inner ends of the base platform 1, and the conveyor belt 103 is tumbled between the two rollers 104. The end of one roller 104 is fixedly connected to the drive shaft of the conveyor motor 102. The motor 102 drives the roller 104 to rotate, which in turn drives the conveyor belt 103 to move and convey the preforms.

[0023] Among them, such as Figure 5 As shown, two guide columns 105 are symmetrically and fixedly connected between the base 1 and the bracket 101. The lifting seat 5 is slidably sleeved on the outside of the guide columns 105, which achieves the purpose of providing a good guiding effect for the lifting seat 5.

[0024] Among them, such as Figure 2 As shown, a side seat 7 is fixedly installed on the side of the bracket 101. The side seat 7 is fixedly sleeved on the outside of the cooling water outlet pipe 201 and the cooling water inlet pipe 202, thereby improving the stability of the assembly structure of the cooling water outlet pipe 201 and the cooling water inlet pipe 202.

[0025] Among them, such as Figure 3 As shown, the heat exchange tube 3 has a serpentine cross-sectional shape and is made of copper, which achieves the purpose of making the heat exchange tube 3 have a good heat exchange effect.

[0026] Among them, such as Figure 1 As shown, two ventilation openings 106 are provided on the inner surface of the base 1. The two ventilation openings 106 are symmetrically distributed to ensure the ventilation performance of the overall structure.

[0027] The working principle of this utility model:

[0028] During use, after the PET masterbatch is melted and extruded into a preform in the injection molding machine, it is conveyed to the area below the fan 601 via the conveying assembly. The cooling water generated by the adsorption chiller 2 enters the heat exchange tube 3 through the cooling water outlet pipe 201 and the L-shaped water guide pipe 301, and then returns to the adsorption chiller 2 through the cooling water inlet pipe 202 and the L-shaped water return pipe 302. The fan 601 is driven to rotate by the blower motor 6. The room temperature airflow generated by the fan 601 can exchange heat with the cooling water flowing in the heat exchange tube 3, thereby obtaining a low temperature airflow that is blown onto the preform, which can quickly cool the preform. If it is necessary to adjust the height of the fan 601, the lifting seat 5 is driven by the electric push rod 4 to move the fan 601 up and down. The L-shaped water guide pipe 301 and the L-shaped water return pipe 302 slide along the cooling water outlet pipe 201 and the cooling water inlet pipe 202, respectively, so that the fan 601 can be adjusted to the required height position.
