Description

Technical Field

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

[0002] Plastic caps are a common form of packaging for bottles, cans, and barrels, especially in the beverage, chemical, and pharmaceutical industries. Based on their uses, they can be divided into breathable plastic caps and non-breathable plastic caps. Plastic bottle caps are generally made of polyolefins as the main raw material. They are made into various shapes of plastic products using plastic molding molds on injection molding equipment. They are then processed through injection molding, hot pressing, and other processes. The injection molding process involves steps such as quantitative feeding, melting and plasticizing, pressure injection, mold filling and cooling, and mold opening and part removal.

[0003] Existing bottle caps are naturally cooled on a conveyor belt after production. The cooling efficiency is greatly affected by the temperature. When the temperature is high, the bottle caps will still have a certain temperature when they are transported to the next process, which will affect the production efficiency of the bottle caps. In order to solve the above problems, this application proposes a cooling device for the production of plastic bottle caps. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] like Figure 1-4 As shown, the present invention proposes a cooling device for the production of plastic bottle caps, including a machine body 1, wherein a cooling roller 2 is rotatably provided in the inner cavity of the machine body 1, the cooling roller 2 is inclined at a 10-degree angle to the horizontal plane, and the feeding end of the cooling roller 2 is higher than the discharging end.

[0028] The inner wall of the cooling drum 2 is welded with a spiral pusher blade 9, and the inner wall of the cooling drum 2 is welded with a lifting plate 10. The lifting plate 10 is arranged in a ring at equal intervals on the inner wall of the cooling drum 2, and the lifting plate 10 penetrates the spiral pusher blade 9. Both ends of the spiral pusher blade 9 and the lifting plate 10 extend to both ends of the inner cavity of the cooling drum 2.

[0029] The bottom of the inner cavity of the machine body 1 is provided with a cooling cover 7. The upper surface of the cooling cover 7 has an arc structure, and the cooling cover 7 is connected to the surface of the cooling roller 2 with a gap.

[0030] The cooling shroud 7 has air intake fans 8 installed at both ends of its sidewall, and the air intake fans 8 are arranged symmetrically.

[0031] It should be noted that the cooling roller 2 is inclined at a 10-degree angle to the horizontal plane, and the feed end of the cooling roller 2 is higher than the discharge end. At the same time, the spiral pusher blade 9 can push the bottle cap to move towards the discharge end. During the movement, the air intake fan 8 and the cooling cover 7 work together to blow cold air into the cooling roller 2, which can quickly cool the bottle cap as it moves forward.

[0032] In this embodiment, as Figure 2 As shown, a drive gear ring 3 is provided at one end of the outer wall surface of the cooling drum 2. The drive gear ring 3 is fixed on the cooling drum 2. An installation groove 14 is opened through the top surface of the machine body 1. The installation groove 14 corresponds to the position of the drive gear 5. A drive motor 4 is installed in the inner cavity of the installation groove 14. The drive gear 5 is connected to the power output end of the drive motor 4. The drive gear 5 is meshed with the drive gear ring 3.

[0033] It should be noted that the drive motor 4 drives the drive gear ring 3 through the drive gear 5, thereby enabling the cooling roller 2 to rotate inside the machine body 1.

[0034] In this embodiment, as Figure 2 As shown, the cooling drum 2 is rotatably connected to two ends of a rotating shaft ring 6. The rotating shaft ring 6 plays a guiding role when the cooling drum 2 rotates. A fixed bracket 13 is welded to the outer wall of the rotating shaft ring 6, and the rotating shaft ring 6 is welded to the inner wall of the machine body 1 through the fixed bracket 13.

[0035] It should be noted that the fixed bracket 13 can fix the rotating shaft ring 6, and the rotating shaft ring 6 can limit the rotation of the cooling drum 2, thereby improving the stability of the cooling drum 2 when it rotates.

[0036] In this embodiment, as Figure 2 As shown, air guide pipes 11 are provided on both sides of the cooling roller 2. The two ends of the air guide pipes 11 are connected to the fixed bracket 13. At the same time, air nozzles 12 are installed at equal intervals on the lower surface of the air guide pipes 11. The air guide pipes 11 are connected to the cooling cover 7 through air pipes.

[0037] It should be noted that during the rotation of the cooling drum 2, the lifting plate 10 can lift the bottle cap on the inner wall of the cooling drum 2. At the same time, the air guide pipe 11 and the air nozzle 12 work together to blow air onto the bottle cap on both sides of the cooling drum 2, which can increase the contact area between the bottle cap and the airflow, thereby improving the cooling efficiency of the bottle cap. Meanwhile, the airflow ejected from the air nozzle 12 can blow the lifted bottle cap off the lifting plate 10, preventing the bottle cap from rising too high, reducing the impact force when the bottle cap falls, and improving the protection of the bottle cap.

[0038] The working principle and usage process of this utility model are as follows: Bottle caps are fed into the cooling roller 2 through the inlet. The drive motor 4 drives the drive gear ring 3 through the drive gear 5, thereby allowing the cooling roller 2 to rotate within the machine body 1. The rotating shaft ring 6 is fixed inside the machine body 1 by the fixed bracket 13. Both ends of the cooling roller 2 are rotatably connected to the rotating shaft ring 6, which guides the rotation of the cooling roller 2. The cooling roller 2 is inclined at a 10-degree angle to the horizontal plane, and the inlet end of the cooling roller 2 is higher than the outlet end. At the same time, the spiral pusher blades 9 push the bottle caps towards the outlet end. During the movement, the air intake fan... 8, when paired with the cooling shroud 7, can blow cold air into the cooling drum 2, which can quickly cool the bottle cap as it moves forward. At the same time, as the cooling drum 2 rotates, the lifting plate 10 can lift the bottle cap on the inner wall of the cooling drum 2. Meanwhile, the air guide pipe 11, paired with the jet nozzle 12, can blow air onto the bottle cap on both sides of the cooling drum 2, which can increase the contact area between the bottle cap and the airflow, thereby improving the cooling efficiency of the bottle cap. At the same time, the airflow ejected from the jet nozzle 12 can blow the lifted bottle cap off the lifting plate 10, preventing the bottle cap from rising too high, reducing the impact force when the bottle cap falls, and improving the protection of the bottle cap.
