Description

Technical Field

[0001] This utility model relates to the technical field of plastic bucket production equipment, and in particular to a precision blow molding, cooling and shaping device for plastic buckets. Background Technology

[0002] The blow molding mechanism in plastic bucket processing refers to the components and working principle of the blow molding machine used to produce plastic buckets. In the blow molding production process of plastic buckets, cooling and shaping after blow molding is a crucial step, as the effect of cooling and shaping directly affects the dimensional accuracy, appearance quality, and physical properties of the plastic bucket.

[0003] For example, Chinese patent CN219055294U discloses a cooling mechanism for blow molding production of plastic buckets, including a basic component and a cooling system. The basic component includes a base and a turntable, with the turntable movably mounted on the base. The cooling system includes a blower, a distribution box, and a water cooling system. The blower and the distribution box are fixedly mounted on the upper end of the base, and the air outlet of the blower is connected to one side of the distribution box.

[0004] Currently, existing plastic buckets are usually cooled directly indoors by natural cooling or by simple air cooling after blow molding. This results in low cooling efficiency and uneven cooling, which not only leads to a long production cycle and increased production costs, but also easily causes quality defects such as deformation and uneven surface, reducing the product qualification rate. To address these issues, a precision blow molding cooling and shaping device for plastic buckets is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, and to propose a precision blow molding, cooling and shaping device for plastic buckets.

The moving device includes a transport plate for placing the plastic buckets. The cooling device includes a cooling box, a shell, a conveying pipe, a return pipe, and a fan. A concentrically arranged inner shell is fixedly installed on the inner wall of the shell. A concentrically arranged outer sealing ring and an inner sealing ring are fixedly connected to the top of the transport plate. The bottom of the shell is inserted into the top of the transport plate. A spiral cooling pipe is fixedly connected between the shell and the inner shell, surrounding the outer wall of the inner shell. The fan is fixedly installed on the top of the shell, and a guide hood is fixedly connected to the bottom of the fan. The bottom end of the guide hood passes through the shell and extends into the inner shell.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figures 1-4As shown, this utility model provides a precision blow molding cooling and shaping device for plastic buckets, including a moving device 1 and a cooling device 2. The moving device 1 includes a conveying plate 16 for placing the plastic buckets. The cooling device 2 includes a cooling box 23, a shell 24, a conveying pipe 27, a return pipe 28, and a fan 29. A concentrically arranged inner shell 210 is fixedly installed on the inner wall of the shell 24. A concentrically arranged outer sealing ring 18 and inner sealing ring 19 are fixedly connected to the top of the conveying plate 16. The bottom of the shell 24 is inserted into the top of the conveying plate 16. A spiral cooling pipe 211 is fixedly connected between the shell 24 and the inner shell 210, surrounding the outer wall of the inner shell 210. The fan 29 is fixedly installed on the top of the shell 24, and a guide shroud 213 is fixedly connected to the bottom of the fan 29. The bottom end of the shroud 213 passes through the outer shell 24 and extends into the inner shell 210. The bottom of the shroud 213 is fixedly connected to a disc 212, and the bottom of the disc 212 is provided with a number of air outlet holes 214 in a ring array. The bottom end of the cooling box 23 is fixedly connected to a cooling pump 26. One end of the cooling pump 26 is fixedly connected to one end of the spiral cooling pipe 211 through a delivery pipe 27. The other end of the spiral cooling pipe 211 is fixedly connected to a return pipe 28, and one end of the return pipe 28 is connected to the cooling box 23. The top of the outer shell 24 is fixedly installed with a protective cover 25 located outside the fan 29. Support frames 21 are symmetrically welded on both sides of the outer shell 24. The outer side of one of the support frames 21 is fixedly installed on the controller 22, and the bottom of the support frame 21 is fixedly installed on the base 11.

[0020] The specific settings and functions of this embodiment are described below: When the hydraulic cylinder 15 pushes the conveying plate 16 and the plastic bucket upward until the plastic bucket is sent into the cooling chamber of the inner shell 210, the bottom end of the outer shell 24 engages with the top of the conveying plate 16. The outer sealing ring 18 and the inner sealing ring 19 are respectively attached to the outer edge and the inner edge of the inner shell 210. Both the outer sealing ring 18 and the inner sealing ring 19 are made of uniformly elastic rubber material, so that the outer sealing ring 18 and the inner sealing ring 19 are tightly attached to the inner shell 210, achieving a good sealing effect and preventing the cold air in the cooling chamber from leaking out, so that the cooling device 2 can cool the plastic bucket better. The controller 22 starts the fan 29 and the cooling pump 26 to begin cooling and shaping the plastic bucket. During the cooling process, the cold air generated by the fan 29 enters the disc 212 through the air guide shroud 213, and finally blows evenly into the cooling chamber through multiple air outlets 214 to cool the plastic bucket. A spiral cooling pipe 211 is arranged between the outer shell 24 and the inner shell 210. The spiral cooling pipe 211 can increase the contact area with the cooling chamber and improve the cooling effect. The cooling pump 26 delivers the cooling water in the cooling tank 23 to the spiral cooling pipe 211 through the delivery pipe 27. In the cooling pipe 211, the cooling water absorbs heat in the spiral cooling pipe 211 and then flows back to the cooling box 23 through the return pipe 28. After passing through the filter in the cooling box 23 to remove impurities, it is recycled again. The cooling device 2, through the combined action of air cooling and water cooling water, can quickly and effectively remove the heat generated by the plastic bucket during the blow molding process, which greatly improves the cooling efficiency. At the same time, the reasonable layout of the air cooling component and the water cooling component can make the plastic bucket cool evenly, avoiding problems such as deformation and uneven surface caused by uneven cooling, thus improving the quality of the product.

[0021] Example 2: Figures 1-3 As shown, the mobile device 1 also includes a base 11, a lead screw 12, a conveying motor 13, a sliding seat 14, and a hydraulic cylinder 15. The output end of the conveying motor 13 is fixedly connected to one end of the lead screw 12. The sliding seat 14 is slidably mounted on the top of the base 11. The inner wall of the sliding seat 14 is threadedly engaged with the outer wall of the lead screw 12. The hydraulic cylinder 15 is fixedly mounted on the top of the sliding seat 14, and the top output end of the hydraulic cylinder 15 is fixedly connected to the transport plate 16. Telescopic rods 17 are symmetrically arranged at both ends of the sliding seat 14, and the top of the telescopic rods 17 is fixedly connected to the bottom of the transport plate 16.

[0022] The overall effect of this embodiment is as follows: after the plastic bucket is blow-molded, the robotic arm smoothly places the plastic bucket on the transport plate 16. The controller 22 automatically controls the start of the conveyor motor 13, which drives the lead screw 12 to rotate, thereby causing the sliding seat 14 and the transport plate 16 to move along the base 11 until the transport plate 16 moves to the cooling position at the bottom of the inner shell 210. Then, the conveyor motor 13 stops running, and the controller 22 automatically controls the start of the hydraulic cylinder 15. The hydraulic cylinder 15 pushes the transport plate 16 and the plastic bucket upward until the plastic bucket is sent into the cooling chamber of the inner shell 210. When the cooling time reaches the set value, the controller 22 shuts off the fan 29 and the cooling pump 26, and at the same time controls the hydraulic cylinder 15 to move the transport plate 16 and the cooled plastic bucket downward to the original height. The conveyor motor 13 drives the lead screw 12 to rotate, thereby conveying the cooled plastic bucket out. The device has a reasonable structural design and is simple and convenient to operate. The operator only needs to control the conveyor motor 13, the hydraulic cylinder 15 and the cooling system to complete the cooling and shaping operation of the plastic bucket.

[0023] The usage and working principle of this device are as follows: After the plastic bucket is blow-molded, the robotic arm places the plastic bucket stably on the conveying plate 16. The conveying motor 13 drives the lead screw 12 to rotate, and the sliding seat 14 and the conveying plate 16 move along the base 11 until the conveying plate 16 moves to the cooling position at the bottom of the inner shell 210. Then, the hydraulic cylinder 15 pushes the conveying plate 16 and the plastic bucket upward until the plastic bucket is sent into the cooling chamber of the inner shell 210. At this time, the bottom end of the outer shell 24 is engaged with the top of the conveying plate 16, so that the outer sealing ring 18 and the inner sealing ring 19 are tightly fitted with the inner shell 210 to prevent the cold air in the cooling chamber from leaking out. The controller 22 starts the fan 29 and the cooling pump 26. During the cooling process, the cold air generated by the fan 29 is blown evenly into the cooling chamber through multiple air outlets 214. A spiral cooling pipe 211 is arranged in a spiral shape between the outer shell 24 and the inner shell 210. The cooling pump 26 delivers the cooling water in the cooling tank 23 to the spiral cooling pipe 211. After absorbing heat in the spiral cooling pipe 211, the cooling water flows back to the cooling tank 23 through the return pipe 28. The cooling device 2 can quickly and effectively remove the heat generated by the plastic bucket during the blow molding process by the combined action of air cooling and water cooling water, thereby improving the cooling efficiency. When the cooling time reaches the set value, the controller 22 turns off the fan 29 and the cooling pump 26. At the same time, it controls the hydraulic cylinder 15 to move the conveying plate 16 and the cooled plastic bucket down to the original height. The conveying motor 13 drives the lead screw 12 to rotate, thereby conveying the cooled plastic bucket out.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
