Description

Technical Field

[0001] This utility model relates to the field of plastic bottle production technology, specifically to a plastic bottle production trimming device. Background Technology

[0002] Plastic bottles are generally produced using blow molding, which has two main processes. The first is extrusion blow molding, which involves adding plastic raw material to an extruder, heating and melting it to extrude a molten preform, closing a mold to clamp the preform, cutting off one end, introducing compressed air to inflate and shape it, cooling and solidifying it before removing it from the mold, and trimming the edges to obtain the finished product. This process is mainly used to produce polyethylene and polyvinyl chloride (PVC) plastic bottles, such as milk bottles and soy sauce bottles. The second is injection blow molding, which involves injecting plastic raw material into a tubular preform using an injection molding machine, then placing it into a bottle mold for stretch blow molding, and cooling to obtain the finished product. This process is mainly used to produce PET plastic bottles, such as mineral water bottles, cola bottles, and Sprite trays. Extrusion blow molding has advantages such as high production efficiency, low equipment cost, and a wide range of mold and machinery options. Currently, 75% of blow-molded products are manufactured using extrusion blow molding.

[0003] Currently, plastic bottles produced through blow molding often have waste scraps that need to be removed before they can be used. These scraps are typically removed manually using blades, but this process is time-consuming, difficult to control in terms of quality, and results in low production efficiency.

[0031] like Figure 1-5As shown in the embodiment of this utility model, a plastic bottle production trimming device includes: a base 10, an extruder 20, a clamping module 30, a conveying module 40, a pressing module 50, and a trimming module 60; the base 10 includes a discharge platform 11 and a worktable 12, the extruder 20 is disposed on the discharge platform 11, the clamping module 30 is disposed on the side of the extruder 20 near the discharge platform 11, the conveying module 40 is disposed on the worktable 12, the pressing module 50 is movably disposed on the conveying module 40, and the trimming module 60... Module 60 is positioned on the workbench 12 near the pressing module 50. The extruder 20 extrudes material towards the pressing module 50, and after clamping, shaping, and cooling the product via the clamping module 30, it is conveyed to the trimming module 60 via the transfer module 40 for trimming the plastic bottle. The trimming module 60 includes a first trimming component 61 and a second trimming component 62, which simultaneously or sequentially trim the upper and lower ends of the plastic bottle on the pressing module 50. In this embodiment, the extruder 20, clamping module 30, transfer module 40, pressing module 50, and trimming module 60 form a highly efficient and automated plastic bottle production line. This integrated design not only optimizes the production process but also significantly improves production efficiency and reduces labor costs. The base 10, with its discharge platform 11 and worktable 12, provides stable support and operating space for the extruder 20, clamping module 30, conveying module 40, pressing module 50, and trimming module 60. The extruder 20, positioned on the discharge platform 11, can precisely extrude molten plastic into shape, while the clamping module 30, located close to the extruder 20, promptly clamps, shapes, and cools the product to ensure the stability of the plastic bottle's shape. This allows the shaped plastic bottle to be smoothly and quickly transported to the next process for trimming. The first trimming component 61 and the second trimming component 62 can simultaneously or sequentially trim the upper and lower ends of the plastic bottle on the pressing module 50, improving trimming accuracy and efficiency. This also ensures that the trimmed plastic bottle has a neat appearance, uniform size, and high practicality.

[0032] like Figures 1 to 3 As shown, the extruder 20 includes an inlet 21, an outlet 22, and a feeding rack 23. A drive unit 24 is provided at one end of the feeding rack 23.

The clamping plate 311 fixes the clamping rod 32 and the clamping cylinder 33 to the clamping frame 311 via the mounting nut 312. The clamping cylinder 33 drives the clamping rod 32 to clamp towards the pressing module 50. In this embodiment, the clamping frame 31, with its clamping plate 311 and mounting nut 312, securely mounts the clamping rod 32 and the clamping cylinder 33. The structure is compact and highly stable, effectively ensuring trimming accuracy and smooth operation of the production line.

[0035] Two sets of clamping rods 32 are provided, each with a through hole 321 facing the pressing module 50. The clamping cylinder 33 drives the adsorption holes on the clamping rods 32 to adsorb the product on the pressing module 50. In this embodiment, by cooperating with the adsorption holes on the two sets of clamping rods 32, the driving force of the clamping cylinder 33 can accurately and stably adsorb the plastic bottle product on the pressing module 50. This allows the pressing module 50 to then transfer the product, after being clamped, cooled, and shaped, to the trimming module 60 via the transfer module 40 for trimming the top and bottom ends of the plastic bottle. This ensures that the product's position is fixed during the trimming process, improving the accuracy and efficiency of trimming, reducing the defect rate caused by product movement, and enhancing the overall stability of the production line and product quality.

[0036] like Figures 4 to 5 As shown, the transmission module 40 includes transmission rods 41 and transmission seats 42.

In this embodiment, the pressing frame 52 and the pressing plate 53 can be firmly fixed by the pressing locking element 511 on the pressing rod 51, making the trimming operation precise and reliable. At the same time, the pressing frame 52 passes through the pressing rod 51, and the pressing plate 53 moves flexibly, making it easy to adjust according to different specifications of plastic bottles, thus enhancing its practicality.

[0038] The pressing plate 53 includes a first pressing block 54 and a second pressing block 55. The first pressing block 54 is provided with a positioning hole 541, and the second pressing block 55 is provided with a positioning pin 551. One end of the positioning pin 551 is inserted into the positioning hole 541 to form a pressing cavity 535. In this embodiment, the pressing plate 53 is formed by the first pressing block 54 and the second pressing block 55; and the positioning hole 541 of the first pressing block 54 and the positioning pin 551 of the second pressing block 55 are interlocked, ensuring the stable formation of the pressing cavity 535, improving positioning accuracy; simplifying the assembly process, and improving production efficiency.

[0039] The first trimming assembly 61 includes a trimming frame 611, a trimming transmission assembly 612, and a first trimming element 613.

There are two sets of lifting and rotating elements 616, and each set of lifting and rotating elements 616 is equipped with a first trimming element 613. The first trimming element 613 is a flat-headed first trimming element 613. In this embodiment, the trimming transmission assembly 612 is cleverly mounted on the trimming frame 611, integrating linear transmission, lateral transmission, and lifting / rotating functions. Both the linear transmission element 614 and the lifting / rotating element 616 are deployed on the lateral transmission element 615, ensuring the flexibility and precision of the trimming action. Two sets of lifting / rotating elements 616 are provided, each equipped with a flat-headed first trimming element 613, enabling them to work collaboratively to efficiently trim the plastic bottles on the pressing module 50.
