Description

A cooling device for preform production Technical Field

[0001] This utility model relates to the field of bottle preform production technology, specifically a cooling device for bottle preform production. Background Technology

[0002] Bottle preforms are semi-finished products produced by injection molding, where raw materials are filled into a mold under specific temperature and pressure. They are then blow molded into the final product. After injection molding, bottle preforms typically retain residual heat, requiring cooling before packaging and transportation. Therefore, providing a cooling device for bottle preform production is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a cooling device for bottle preform production, thereby solving the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for bottle preform production, comprising a housing, an inlet pipe connected to one side of the upper part of the housing, and an outlet pipe connected to the other side of the lower part of the housing. A rotatable belt is installed inside the housing via a pair of pulleys. One of the pulleys is connected to the power output end of a motor. Multiple partitions are fixedly installed on the outside of the belt. When the belt rotates, the partition located below the inlet pipe can move downwards. A chamber for accommodating bottle preforms is formed between the partitions, the housing, and the belt. Each partition has multiple through holes, and each through hole also has a one-way ventilation structure. When the partition moves downwards, the one-way ventilation structure opens, allowing gas to pass through the partition. An air inlet is provided at the bottom of the housing, vertically corresponding to the side of the partition that moves downwards. An air outlet is provided at the top of the housing near the inlet pipe.

[0005] Preferably, a cooler and a fan are fixedly installed on the outside of the housing, the air outlet of the fan is connected to the air inlet of the cooler, and the air outlet of the cooler is connected to the air inlet through an air supply pipe.

[0006] Preferably, the air outlet is connected to the air inlet of the fan via a recovery pipe.

[0007] Preferably, the one-way ventilation structure includes a mounting cylinder fixedly connected to one end of the through hole. A side hole is provided on the side wall of the mounting cylinder, and a piston block is slidably disposed inside the mounting cylinder. When the partition moves downward, the mounting cylinder is located below the through hole. At this time, the piston block can move to below the side hole by its own weight, allowing the gas below the partition to enter the through hole through the side hole, thus realizing gas flow. When the block moves upward, the mounting cylinder is located above the through hole. At this time, the piston block can block the through hole due to its own weight.

[0008] Preferably, a pair of support plates are provided inside the housing on the inner side of the belt.

[0009] Beneficial effects

[0010] This utility model provides a cooling device for bottle preform production, which has the following advantages: Bottle preforms can be placed on a conveyor belt with baffles; the residence time of the preforms in the chamber can be controlled by controlling the belt's rotation speed, thereby controlling the cooling time. The air inlet is located at the bottom, so when cold air enters the chamber, it first contacts the bottommost preform, ensuring cooling when it exits. Simultaneously, the cold air is appropriately heated before contacting the newly entered preforms, preventing excessive temperature differences between the preforms and the cold air. Because a one-way ventilation structure is designed on the through-hole, the through-hole opens only when the baffle moves downwards and closes when the baffle moves upwards, restricting the gas flow path and achieving efficient utilization of cold air, thus avoiding energy waste.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please refer to Figures 1-3. This utility model provides a technical solution: a cooling device for bottle preform production, including a housing 1. A feed pipe 2 is connected to one side of the upper part of the housing 1, and a discharge pipe 3 is connected to the other side of the lower part of the housing 1. A rotatable belt 5 is provided inside the housing 1 via a pair of pulleys 4. The belt 5 is a toothed belt, and the pulleys 4 are matched with the toothed belt. One of the pulleys 4 is connected to the power output end of a motor (not shown in the figure). The motor drives the pulley 4 to rotate. Multiple partitions 6 are fixedly installed on the outside of the belt 5. When the belt 5 rotates, the partition 6 located below the feed pipe 2 can move downwards, forming a chamber for accommodating the preform between the partition 6, the box body 1, and the belt 5. Each partition 6 has multiple through holes 7 for gas to pass through, and each through hole 7 also has a one-way ventilation structure. When the partition 6 moves downwards, the one-way ventilation structure can be opened, allowing gas to pass through the partition 6. An air inlet 8 is provided at the bottom of the box body 1, and the air inlet 8 is vertically aligned with the side of the partition 6 that moves downwards. An air outlet 9 is provided at the top of the box body 1 near the feed pipe 2.

[0017] As an embodiment of this utility model, a cooler 10 and a fan 11 are fixedly installed on the outside of the housing 1. The air outlet of the fan 11 is connected to the air inlet of the cooler 10, and the air outlet of the cooler 10 is connected to the air inlet 8 through the air supply pipe 12.

[0018] As an embodiment of this utility model, the air outlet 9 is connected to the air inlet of the fan 11 through the recovery pipe 13.

[0019] As an embodiment of this utility model, the one-way ventilation structure includes a mounting cylinder 14 fixedly connected to one end of the through hole 7. A side hole 15 is provided on the side wall of the mounting cylinder 14. A piston block 16 is slidably disposed inside the mounting cylinder 14. When the partition 6 moves downward, the mounting cylinder 14 is located below the through hole 7. At this time, the piston block 16 can move to below the side hole 15 by its own weight, so that the gas below the partition 6 can enter the through hole 7 through the side hole 15 to realize the flow of gas. When the block moves upward, the mounting cylinder 14 is located above the through hole 7. At this time, the piston block 16 can block the through hole 7 due to its own weight.

[0020] As an embodiment of this utility model, a pair of support plates 17 are provided inside the box 1 on the inner side of the belt 5. The support plates 17 can support the belt 5 and prevent the gap between the end of the partition 6 and the inner wall of the box 1 from being too large.

[0021] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0022] The working principle and usage process of this utility model are as follows: In use, the feed pipe 2 is connected to the discharge end of the injection molding machine. Starting the motor causes the pulley 4 to rotate, which in turn drives the belt 5 to rotate within the housing 1. This causes the partition 6 located below the feed pipe 2 to move downwards, allowing the preform discharged from the feed pipe 2 to fall onto the partition 6 by its own weight. Starting the fan 11 and the cooling fan 10 allows cold air to be blown into the housing 1 through the air inlet 8. The cold air passes through the through-hole 7 to cool the preform on the partition 6. Since the air inlet 8 is located at the bottom, when the cold air enters the housing 1, it first contacts the bottommost preform, ensuring that the preform is cooled upon discharge. Simultaneously, the cold air is appropriately heated before contacting the newly entered preform. The preforms in the chamber 1 are in contact with each other, which also prevents the temperature difference between the preforms and the cold air from being too large. The time the preforms stay in the chamber 1 can be controlled by controlling the speed of the belt 5, thereby adjusting the cooling time of the preforms. Since a one-way ventilation structure is set on the through hole 7, the through hole 7 can only be opened when the partition 6 moves downward and the through hole 7 is closed when the partition 6 moves upward, which restricts the flow path of the gas, realizes the efficient use of cold air, and avoids energy waste. When the partition 6 rotates to the bottom and is in a vertical state, the preforms on the partition 6 can fall into the bottom of the chamber 1 by their own weight. The bottom of the chamber 1 has a bucket-shaped structure, and the discharge pipe 3 is connected to the lowest point of the bucket-shaped structure. Finally, the cooled preforms are discharged from the chamber 1 through the discharge pipe 3.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
