Description

Technical Field

[0001] This utility model relates to the field of storage device technology, specifically a raw material storage device for bottle preform injection molding. Background Technology

[0002] Bottle preforms are formed by filling the mold with raw materials under specific temperature and pressure during injection molding. They are then formed under the working conditions of the injection molding machine and become intermediate semi-finished products through injection molding. They are then blow molded into final products. Bottle preform injection molding raw materials need to be stored before entering the injection molding machine for use.

[0003] However, when high humidity air enters the tank, the raw materials are easily damp, affecting the injection molding quality. Therefore, providing a moisture-proof storage device that can prevent external humid air from entering the tank and can efficiently dry the raw materials is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a raw material storage device for preform injection molding, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material storage device for preform injection molding, comprising a tank body, an exhaust pipe fixedly disposed at the center of the tank body, multiple annular air supply cylinders of different heights fixedly disposed on the inner wall of the tank body, an air supply pipe fixedly disposed on the outer side of the tank body, each annular air supply cylinder being connected to the air supply pipe via a connecting pipe, a valve being disposed on the connecting pipe, a filter box being connected to the air supply pipe, an exhaust fan being connected to the exhaust pipe, a feed pipe being connected to the top of the tank body, and a discharge pipe being connected to the bottom of the tank body.

[0006] Preferably, a gas heater is provided on the gas supply pipe at the gas outlet of the filter box.

[0007] Preferably, the filter box contains a filter plate one, a filter plate two, and a desiccant arranged sequentially along the gas flow direction.

[0008] Preferably, the feed pipe is equipped with a second valve.

[0009] Preferably, the upper end of the annular air supply cylinder is inclined towards the inner side of the tank.

[0010] Beneficial effects

[0011] This utility model provides a raw material storage device for bottle preform injection molding, which has the following beneficial effects: starting the exhaust fan can draw outside air into the tank; the desiccant in the filter box can prevent humid air from entering the tank; the annular air supply cylinder can make the gas outlet located at the side wall of the tank, so that the gas passes through the raw material from the outside to the inside, reducing the dead zone of gas flow; and the gas heater can heat the gas entering the air supply pipe, improving the drying efficiency of the raw material.

[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 see Figures 1-2 This utility model provides a technical solution: a raw material storage device for bottle preform injection molding, including a tank body 1, an exhaust pipe 2 fixedly installed at the center of the tank body 1, multiple annular air supply cylinders 3 of different heights fixedly installed on the inner wall of the tank body 1, an air supply pipe 6 fixedly installed on the outer side of the tank body 1, each annular air supply cylinder 3 being connected to the air supply pipe 6 via a connecting pipe 4, a valve 5 installed on the connecting pipe 4, a filter box 7 connected to the air supply pipe 6, an exhaust fan 8 connected to the exhaust pipe 2, a feed pipe 9 connected to the top of the tank body 1, and a discharge pipe 10 connected to the bottom of the tank body 1. Activating the exhaust fan 8 allows the material to pass through the exhaust pipe at the center of the tank body 1. The air pipe 2 extracts the gas from the tank 1, creating a negative pressure inside the tank 1. This negative pressure draws in outside air, which is filtered by the filter box 7 before entering the tank 1. The gas is then discharged through the air supply pipe 6 and the connecting pipe 4 via the annular air supply cylinder 3. The annular air supply cylinder 3 allows the gas outlet to be located on the side wall of the tank 1, enabling the gas to pass through the raw material from the outside in, reducing dead zones in the gas flow. Depending on the storage conditions of the raw material in the tank 1, closing valve 5 controls the exhaust of the annular air supply cylinder 3 at different heights, preventing the gas from being directly sucked out by the exhaust pipe 2 without passing through the raw material.

[0017] Furthermore, a gas heater 11 is installed on the gas supply pipe 6 at the gas outlet of the filter box 7. The gas heater 11 can heat the gas entering the gas supply pipe 6, thereby improving the drying efficiency of the raw materials.

[0018] Specifically, filter box 7 is provided with filter plate 12, filter plate 13 and desiccant 14 arranged in sequence along the gas flow direction. Filter plate 12 and filter plate 13 can filter dust in the gas, and desiccant 14 can adsorb moisture in the air.

[0019] Furthermore, a valve 2 15 is installed on the feed pipe 9. Except for discharging material into the tank 1, the valve 2 15 is normally closed to prevent external air from entering the tank 1 through the feed pipe 9 when the exhaust fan 8 is working.

[0020] Furthermore, the upper end of the annular air supply cylinder 3 is inclined towards the inside of the tank body 1 to avoid raw materials remaining on the annular air supply cylinder 3.

[0021] 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.
