Description

Technical Field

[0001] This utility model relates to the technical field of injection molding cooling devices for plastic bottle production, specifically a plastic bottle injection molding cooling device. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials, adding appropriate organic solvents, and then heating at high temperatures before being molded into plastic containers through blow molding, extrusion blow molding, or injection molding. However, existing equipment still has some shortcomings; for example…

[0003] For example, a cooling device for plastic bottle production, as described in announcement number CN213563853U, includes a frame. Shafts are located on both sides of the upper end of the frame, with a conveyor belt wound around the outside of the shafts. One end of the shaft extends out of the frame and is mounted in front of a motor. A housing is located at the upper end of the frame, and a water collection tank is located at the bottom of the housing. A water tank is located outside the frame, and a pipe connects the water tank and the water collection tank. A water pump is located outside the housing and is bolted to the outside of the housing. The water pump and the water tank are connected by a conduit, with the upper end of the conduit extending into the housing. Multiple nozzles are located at the bottom of the conduit inside the housing. This device has some problems. While it can be used effectively to quickly cool plastic bottles after production, it typically only cools the same type of plastic bottles. Because it is not suitable for cooling different types of plastic bottles, the cooling effect is difficult to achieve the desired results. Therefore, we propose a cooling device for injection molding of plastic bottles to solve the aforementioned problems. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-4This utility model provides a technical solution: a cooling device for injection molding in plastic bottle production, comprising a machine body 1, a conveyor belt 2 connected to the top of the machine body 1, and through holes 3 arranged in an array on the surface of the conveyor belt 2. The machine body 1 is internally connected to a moving mechanism and a baffle 9. The moving mechanism includes a push rod 4, a connecting block 5, a connecting rod 6, an adjusting plate 7, a sliding rod 8, and the baffle 9. The push rod 4 is fixedly connected to the inside of the machine body 1, and the front end of the push rod 4 is fixedly connected to the connecting block 5. The connecting block 5 is slidably connected to the inside of the machine body 1, and the connecting block 5 is hinged to the connecting rod 6. The end and the adjusting plate 7 are hinged, and the adjusting plate 7 and the slide rod 8 are slidably connected. The slide rod 8 is fixedly connected to the inside of the machine body 1. The adjusting plate 7 and the baffle 9 are fixedly connected. The moving mechanism is symmetrically arranged about the center of the machine body 1, and the front end of the moving mechanism is connected to the baffle 9. The baffle 9 is arranged on both sides of the conveyor belt 2. The machine body 1 is equipped with a water tank 10, and the water tank 10 is connected to the nozzle 11. The nozzle 11 is arranged in an array below the water tank 10, and the nozzle 11 is connected to the water pump inside the water tank 10. The machine body 1 is equipped with a collection box 12, and the collection box 12 is connected to the water tank 10 through the water supply pipe 13.

[0021] During use, after the injection-molded plastic bottle is placed above the conveyor belt 2, the push rods 4 on both sides inside the machine body 1 are activated to move the connecting block 5. After the connecting block 5 slides inside the machine body 1, the connecting block 5 drives the connecting rod 6 through the hinge shaft to adjust it. The connecting rod 6 drives the adjusting plate 7 to slide above the slide rod 8. Then, the adjusting plate 7 drives the baffle 9 to move to the sides of the plastic bottle to prevent the plastic bottle from falling during the conveying process. After the conveyor belt 2 is activated to transport the plastic bottle into the machine body 1, the spray nozzle 11 inside the machine body 1 is activated to spray the cold water in the water tank 10 onto the surface of the plastic bottle to cool it quickly. The excess cold water generated during the cooling process enters the collection box 12 below through the through hole 3 on the surface of the conveyor belt 2 for collection. Since the surface of the newly injection-molded plastic bottle is clean, the cold water collected in the collection box 12 can be pumped into the water tank 10 through the water pipe 13 for reuse.

[0022] The machine body 1 has an air storage chamber 24 inside, and a hot air mechanism is installed inside the air storage chamber 24. The hot air mechanism includes an air pump 14, a filter screen 15, an electric heating wire 16, and the air storage chamber 24. The air pump 14 is installed above the air storage chamber 24, and the filter screen 15 and electric heating wire 16 are installed inside the air storage chamber 24. The machine body 1 is connected to the adjustment block 22 through an adjustment mechanism. The adjustment mechanism includes a motor 18, a first gear 19, a half-shaft gear 20, a support plate 21, and an adjustment block 22. The machine body 1 is fixedly connected to the motor 18, and the motor 18 is connected to the first gear 19. The first gear 19 meshes with the half-shaft gear 20. The half-shaft gear 20 is hinged to the support plate 21, and the half-shaft gear 20 is fixedly connected to the adjustment block 22. The surface of the adjustment block 22 is connected to the nozzle 23, and the nozzle 23 is connected to the inside of the air storage chamber 24 through an air supply pipe 17.

[0023] At this time, the cooled plastic bottles are conveyed by conveyor belt 2. At the same time, the air pump 14 is started to draw air into the air storage chamber 24. After being filtered by the internal filter screen 15, the air is heated by the heating wire 16. The heated air is then drawn into the nozzle 23 through the air supply pipe 17 and sprayed onto the surface of the plastic bottle for drying. Due to the different shapes and structures of the bottles, the motor 18 can be started to drive the first gear 19 to rotate. Since the first gear 19 meshes with the half-shaft gear 20, the half-shaft gear 20 is adjusted around the support plate 21, which drives the adjusting block 22 to adjust. The adjusting block 22 then drives the multiple nozzles 23 on the surface to adjust, so as to better dry the bottles with different shapes and structures and change the airflow direction of the nozzles 23, so that the moisture on the surface of the plastic bottle evaporates quickly.

[0024] Working Principle: When using the injection molding cooling device for plastic bottle production, after the injection-molded plastic bottle is placed above the conveyor belt 2, the push rods 4 on both sides inside the machine body 1 are activated to move the connecting block 5. After the connecting block 5 slides inside the machine body 1, the connecting block 5 drives the connecting rod 6 through the hinge shaft to adjust. The connecting rod 6 then drives the adjusting plate 7 to slide above the slide rod 8. At this time, the adjusting plate 7 drives the baffle 9 to move to the sides of the plastic bottle to prevent the plastic bottle from falling during the conveying process. Then, the conveyor belt 2 is activated to transport the plastic bottle into the machine body 1. Then, the nozzles 11 inside the machine body 1 are activated to spray cold water from the water tank 10 onto the surface of the plastic bottle to quickly cool it. The excess cold water generated during the cooling process enters the collection box 12 below through the through holes 3 on the surface of the conveyor belt 2 for collection. Since the surface of the freshly injection-molded plastic bottle is clean, the cold water collected in the collection box 12 can be pumped into the water tank 10 through the water pipe 13. Inside, the plastic bottles are reused. After cooling, they are conveyed by conveyor belt 2. At the same time, the air pump 14 is activated to draw air into the air storage chamber 24. After being filtered by the internal filter screen 15, the air is heated by the heating wire 16. The heated air is then drawn into the nozzle 23 through the air supply pipe 17 and sprayed onto the surface of the plastic bottle for drying. Due to the different shapes and structures of the bottles, the motor 18 can be activated to drive the first gear 19 to rotate. Since the first gear 19 meshes with the half-shaft gear 20, the half-shaft gear 20 is adjusted around the support plate 21, which in turn drives the adjusting block 22 to adjust. The adjusting block 22 then drives the multiple nozzles 23 on the surface to adjust, thus better drying bottles of different shapes and structures. The airflow direction of the nozzles 23 is changed, so that the moisture on the surface of the plastic bottle evaporates quickly, thereby completing a series of operations. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
