Description

A cooling mechanism for blow molding of plastic bottles Technical Field

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

[0002] The cooling mechanism for blow molding of plastic bottles is a crucial component in the plastic bottle production process. It primarily serves to rapidly cool the plastic bottles after blow molding to ensure shape stability and dimensional accuracy. Existing technology includes a patent (CN 221365798 U) that discloses a plastic bottle blow molding cooling machine, comprising a worktable, a blow molding assembly, a traveling assembly, and a cooling assembly. The worktable has a support on its lower surface and a blow molding chamber on the front side of its upper surface. The blow molding assembly is located inside the blow molding chamber. The traveling assembly is located inside the worktable. The cooling assembly is located on the rear side of the upper surface of the worktable and also includes a microcontroller. During the cooling process, because the fan position is fixed, cooling air is blown in from the top of the cooling chamber, leading to uneven air distribution. Cooling air is mainly concentrated in the upper part of the plastic bottle, while the lower part experiences relatively poor cooling. This uneven cooling results in different cooling rates between the upper and lower parts of the plastic bottle, causing deformation or inconsistent dimensions. Therefore, we propose a cooling mechanism for blow molding of plastic bottles. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a cooling mechanism for blow molding of plastic bottles. Through the cooperation of the connecting plate and the transmission plate, the fan can be driven to perform lateral reciprocating motion, thereby dynamically adjusting the distribution of cooling air so that the cooling air can cover the surface of the plastic bottle more evenly, improving the uniformity of the cooling effect, solving the problem of plastic bottle deformation or inconsistent size caused by uneven cooling, and effectively solving the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cooling mechanism for blow molding of plastic bottles, comprising a cover and a cooling assembly;

[0005] Cooling assembly: It includes mounting rods, connecting plates, transmission plates, and cooling seats. The mounting rods are rotatably connected to the middle of the front and rear walls of the cover. Connecting plates are provided in the middle of the outer arc surface of the mounting rods. Transmission plates are rotatably connected to the left and right sides of the end of the connecting plate near the center of the inside of the cover. Cooling seats are provided on the front and rear sides of the inside of the cover. The end of the transmission plate near the center of the inside of the cover is rotatably connected to the middle of the end of the cooling seat away from the center of the inside of the cover. Through the cooperation of the connecting plates and transmission plates, the fan can be driven to perform lateral reciprocating motion, thereby dynamically adjusting the distribution of cooling air, so that the cooling air can cover the surface of the plastic bottle more evenly, improving the uniformity of the cooling effect, and solving the problem of plastic bottle deformation or inconsistent size caused by uneven cooling.

The outer arc surface of the cam contacts the left surface of the horizontally adjacent vertical plate, which can drive the rack plate to move through the vertical plate.

[0011] Furthermore, motors are respectively installed on the lower side of the end of the protective cover away from the center of the cover. The end of the motor output shaft near the center of the cover is fixedly connected to the end of the longitudinally adjacent output rod away from the center of the cover.

[0018] 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.

[0019] Please refer to Figures 1-3. This embodiment provides a technical solution: a cooling mechanism for blow molding of plastic bottles, including a cover 1 and a cooling component 3;

[0020] Cooling assembly 3 includes mounting rods 31, connecting plates 32, transmission plates 33, and cooling seats 35. The mounting rods 31 are rotatably connected to the middle of the front and rear walls of the cover 1. Connecting plates 32 are provided at the middle of the outer arc surface of each mounting rod 31. Transmission plates 33 are rotatably connected to the left and right sides of the end of the connecting plate 32 closest to the center of the cover 1. Cooling seats 35 are provided on the front and rear sides inside the cover 1. The end of the transmission plate 33 closest to the center of the cover 1 is rotatably connected to the middle of the end of the cooling seat 35 furthest from the center of the cover 1. Cooling assembly 3 also includes a crossbar 34, a fan 36, and an air inlet 37. Rods 34 are respectively set on the upper and lower sides inside the protective cover 4. Two vertically adjacent horizontal rods 34 are slidably connected to the sliding holes corresponding to the left end of the cooling seat 35. A fan 36 is set in the middle of the front end of the cooling seat 35. An air inlet 37 is set on the upper side of both the front and rear ends of the cover 1. Through the cooperation of the connecting plate 32 and the transmission plate 33, the fan 36 can be driven to perform horizontal reciprocating motion, thereby dynamically adjusting the distribution of cooling air, so that the cooling air can cover the surface of the plastic bottle more evenly, improving the uniformity of the cooling effect, and solving the problem of plastic bottle deformation or inconsistent size caused by uneven cooling.

[0021] It also includes a control switch group 2, which is located at the front end of the cover 1. The input end of the control switch group 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0022] Among them: protective covers 4 are respectively provided on the lower sides of the front and rear ends of the cover 1. Hexagonal sliding columns 5 are provided in the middle between the left and right walls of the protective cover 4. A rack plate 6 is slidably connected to the right side of the outer surface of the hexagonal sliding column 5. A gear 7 is provided on the side of the outer arc surface of the mounting rod 31 away from the inner center of the cover 1. The gear 7 is meshed with the vertically adjacent rack plate 6. During the movement, the rack plate 6 will drive the gear 7 to rotate through the meshing connection. During the rotation, the gear 7 will drive the connecting plate 32 to rotate through the mounting rod 31.

[0023] Among them, springs 8 are respectively installed between the right end of the rack plate 6 and the right wall of the protective cover 4. The springs 8 are all sleeved on the outside of the right side of the hexagonal sliding column 5. The thrust generated by the extension of the spring 9 will drive the rack plate 6 to move to the left and reset.

[0024] Specifically: a vertical plate 9 is provided on the right side of the lower end of the rack plate 6, and an output rod 10 is rotatably connected to the lower side inside the protective cover 4. A cam 11 is provided in the middle of the outer arc surface of the output rod 10. The outer arc surface of the cam 11 contacts the left surface of the horizontally adjacent vertical plate 9. When the contact point between the cam 11 and the vertical plate 9 changes from the proximal to the distal, the vertical plate 9 will be pushed to the right by the cam 11. During the movement of the vertical plate 9, the rack plate 6 will move to the right.

[0025] Among them, motors 12 are respectively installed on the lower side of the end of the protective cover 4 away from the center of the inside of the cover 1. The end of the output shaft of the motor 12 near the center of the inside of the cover 1 is fixedly connected to the end of the longitudinally adjacent output rod 10 away from the center of the inside of the cover 1. The input end of the motor 12 is electrically connected to the output end of the control switch group 2. The motor 12 starts to run through the control switch group 2. The output shaft of the motor 12 drives the cam 11 to rotate through the output rod 10.

[0026] The working principle of the plastic bottle blow molding cooling mechanism provided by this utility model is as follows: Before use, the cover 1 is installed and connected with the external conveying equipment to support and fix the cover 1 and the internal equipment. Subsequently, during the operation of the plastic bottle blow molding cooling mechanism, when the external conveying equipment sends the blown plastic bottle into the interior of the cover 1, the fan 36 starts to run through the control switch group 2. The fan 36 generates airflow through high-speed rotation, and the external cooling air enters the interior of the cover 1 through the air inlet 37. Then, the fan 36 cools the air... Air is blown onto the surface of the plastic bottle. As the plastic bottle moves inside the enclosure 1, the cooling air comes into contact with the surface of the plastic bottle. At this time, the cooling air carries away the heat from the plastic bottle through heat transfer (mainly convection heat transfer), thereby reducing the temperature of the plastic bottle. During the operation of the fan 36, the motor 12 starts to run through the control switch group 2. The output shaft of the motor 12 drives the cam 11 to rotate through the output rod 10. When the contact point between the cam 11 and the vertical plate 9 changes from proximal to distal, the vertical plate 9 will be pushed to the right by the cam 11. The movement process causes the rack plate 6 to move to the right, and the spring 8 to contract. During the movement, the rack plate 6 drives the gear 7 to rotate through meshing. During the rotation of the gear 7, the connecting plate 32 is driven to rotate through the mounting rod 31. At this time, the connecting plate 32 provides a thrust to the cooling seat 35 through the transmission plate 33, thereby causing the connecting plate 32 to drive the fan 36 to move away from the center of the housing 1. When the contact point between the cam 11 and the vertical plate 9 changes from the distal center to the proximal center, the thrust generated by the extension of the spring 9 will drive the rack plate 6 to move towards the center. When the rack plate 6 moves to the left and resets, it will drive the gear 7 to rotate through meshing during the movement. During the rotation of the gear 7, it will drive the connecting plate 32 to rotate through the mounting rod 31. At this time, the connecting plate 32 will exert a pulling force on the cooling seat 35 through the transmission plate 33, thereby causing the connecting plate 32 to drive the fan 36 to move towards the end closer to the center of the inside of the cover 1 through the transmission plate 33. This will drive the fan 36 to perform a lateral reciprocating motion, so that the cooling air can be blown evenly to the plastic bottle from multiple directions, ensuring that all parts of the plastic bottle are fully cooled.

[0027] It is worth noting that the motor 12 disclosed in the above embodiments can be ECMA-C20604RS, the fan 36 can be ME92252V1-000C-A99, and the control switch group 2 is provided with control buttons corresponding to the fan 36 and the motor 12 for controlling their switching.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
