Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, specifically a blow molding machine for cosmetic bottle production. Background Technology

[0002] In the cosmetic packaging industry, plastic blow molding machines are a key piece of equipment, widely used to manufacture plastic bottles of various shapes and sizes, especially containers for liquid or cream products such as cosmetics and skincare products. Blow molding machines work by blowing air into the preform inside a mold to make it expand. The shape and pattern of the bottle body are formed by the shape and pattern inside the mold. However, due to the wide variety of bottle types and the differences in surface patterns even for bottles of the same size, different types of molds are required when blow molding machines are needed to form different types of bottles. Existing molds are basically installed inside the cylinder by multiple bolts. When different molds need to be changed according to the needs of the bottle, the bolts need to be tightened repeatedly to disassemble or install them, making the installation and disassembly cumbersome and inconvenient for users.

[0003] A search of Chinese Patent Publication No. CN202421186103.7 reveals a blow molding mechanism for a blow molding machine. This device, through its disassembly mechanism, allows for quick installation and removal of molds. When different types of molds need to be changed according to the bottle size, it effectively saves the time and effort required by traditional methods of repeatedly tightening bolts, making it more convenient to use. Furthermore, the faster replacement speed reduces the time spent on mold changes, allowing the equipment to enter the blow molding process more quickly, thus relatively increasing the production speed of blow molding. However, some problems still exist in actual use. After the bottle is blown, it needs to be manually removed. However, the bottle is still hot when it is freshly formed, and removing it can easily cause deformation or leave marks, as well as burns from the heat of the bottle itself. Additionally, the device requires manual insertion of the preform for blow molding, and manual removal after blowing is complete, which is time-consuming and labor-intensive, reducing bottle production efficiency.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0026] like Figures 1-7 As shown, a blow molding machine for cosmetic bottle production includes: a mounting frame 1, a housing 11 fixedly mounted on the top of the mounting frame 1, a feed cylinder 12 and a discharge cylinder 13 fixedly connected to one side of the housing 11, an annular guide rail conveyor 14 fixedly mounted on the top of the mounting frame 1, the annular guide rail conveyor 14 being located inside the housing 11, the feed cylinder 12 and the discharge cylinder 13, and a plurality of equidistantly distributed feeding seats 15 fixedly mounted on one side of the chain of the annular guide rail conveyor 14; a blow molding assembly, the blow molding assembly being located inside the housing 11 for blow molding the preform; and a cooling assembly, the cooling assembly being located inside the discharge cylinder 13 for cooling the blow-molded cosmetic bottle.

[0027] In the production of cosmetic bottles, the preform is placed on the loading seat 15 and conveyed to the feeding cylinder 12 by the annular guide rail conveyor 14. A heating module can be installed on one side of the inner wall of the feeding cylinder 12 to heat the preform, which helps the preform to be blow-molded. After the heated preform moves into the shell 11, it is blow-molded into the shape of a cosmetic bottle by the blow molding assembly. The molded cosmetic bottle enters the discharge cylinder 13 and is cooled down by the cooling assembly to make the cosmetic bottle harden quickly and avoid deformation and twisting. In conjunction with the annular guide rail conveyor 14, it can carry out continuous processing and improve the production efficiency of cosmetic bottles. Example

[0028] Based on Embodiment 1, the blow molding assembly includes: mounting plate 2, cylinder a21, molding die 22, guide rod 23, moving plate 24, blow molding head 25, and cylinder b26. Two mounting plates 2 are provided inside the housing 11. Cylinder a21 is fixedly mounted on each of the two mounting plates 2. Molding die 22 is fixedly mounted on both ends of cylinder a21. Multiple guide rods 23 are fixedly connected to the bottom plate of the mounting frame 1 at positions opposite to the molding die 22. The moving plate 24 is slidably connected to the outside of the multiple guide rods 23. Blow molding head 25 is fixedly mounted on the top of the moving plate 24. Cylinder b26 is fixedly mounted on the bottom plate of the mounting frame 1. The output end of the top of cylinder b26 is connected to the bottom of the moving plate 24. Air holes 27 are provided inside the feeding seat 15. Through holes 28 are provided at the top of the mounting frame 1 at positions opposite to the blow molding head 25. Induction coils 29 are fixedly mounted on the bottom of the feeding seat 15. A position sensor 210 is fixedly mounted on the top of the moving plate 24.

[0029] The preform on the loading seat 15 is conveyed into the housing 11 via the annular guide rail conveyor line 14. When the loading seat 15 moves to the position of the through hole 28, the induction coil 29 is aligned with the position sensor 210. The position sensor 210 detects the induction coil 29 and controls the annular guide rail conveyor line 14 to stop working. At this time, the air hole 27, the through hole 28, and the blow molding head 25 are aligned. Then, the two cylinders a21 are activated to push the two molding dies 22 to move relative to each other, clamping the preform along with the loading rod at the top of the loading seat 15. Then, the cylinder b26 is activated to push the moving plate 24 upward. The moving plate 24 moves smoothly along the outside of the guide rod 23. The moving plate 24 pushes the blow molding head 25 upward to enter the through hole 28 and insert it into the air hole at the bottom of the loading seat 15. In the hole 27, the blow molding head 25 starts working and delivers compressed gas into the hole 27. The compressed gas enters the preform through the hole 27. After being heated, the preform has good ductility and blows the preform into the shape inside the plastic molding die 22, completing the processing of the cosmetic bottle. Then, the cylinder b26 retracts and drives the moving plate 24 to move downward, so that the top of the blow molding head 25 is pulled out from the hole 27, and the gas inside the cosmetic bottle is discharged from the hole 27. The two cylinders a21 retract and drive the two molding dies 22 to separate and complete the demolding. The annular guide rail conveyor line 14 starts working again. The molded cosmetic bottle enters the discharge cylinder 13 under the drive of the annular guide rail conveyor line 14, and then is removed from the discharge cylinder 13. The cosmetic bottle can be manually removed from the loading seat 15. Example

[0030] Based on Embodiment 1, the cooling assembly includes: a fan 3, a housing 31, a partition plate 32, a water storage chamber 33, a spray chamber 34, ventilation holes 35, and a wet curtain 36. The fan 3 is fixedly installed at the bottom of the discharge cylinder 13, and the housing 31 is fixedly installed on one side of the fan 3. The partition plate 32 is fixedly connected between the inner walls of the housing 31. The partition plate 32 can divide the interior of the housing 31 into the water storage chamber 33 and the spray chamber 34. Ventilation holes 35 are opened on opposite sides of the spray chamber 34. The wet curtain 36 is fixedly installed inside the spray chamber 34. A water pump 37 is installed inside the water storage chamber 33. A water supply pipe 38 is fixedly connected to the output end of the water pump 37. One end of the water supply pipe 38 is connected to the input end of the top of the wet curtain 36. A drain outlet 39 is opened on the partition plate 32.

[0031] During the production of cosmetic bottles, clean water is added into the water storage chamber 33. Then, the water pump 37 and the blower fan 3 are started. After the water pump 37 starts, the clean water inside the water storage chamber 33 is extracted and transported to the top of the wet curtain 36 through the water delivery pipe 38. The clean water flows down from the top of the wet curtain 36 and then flows back into the water storage chamber 33 through the drain outlet 39. After the blower fan 3 starts, fresh air from outside is drawn into the spray chamber 34 through the ventilation hole 35. The temperature of the fresh air is reduced as it passes through the wet curtain 36. It is then drawn into the discharge cylinder 13 by the blower fan 3. When the cosmetic bottle moves in the discharge cylinder 13, the cold air blown out by the blower fan 3 cools the cosmetic bottle, allowing it to solidify quickly and preventing deformation when it is removed.
