Description

Technical Field

[0001] This utility model belongs to the field of plastic bottle production technology, specifically a piece of equipment for producing plastic bottles. Background Technology

[0002] Plastic bottles are mainly made from materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials, adding appropriate organic solvents, and then, after being heated at high temperatures, are formed into plastic containers through blow molding, extrusion blow molding, or injection molding using plastic molds.

[0003] When plastic bottles are made using plastic molds, existing molds can often only produce one type of plastic material. When different types of plastic bottles need to be made, the molds need to be changed, which requires machine downtime. This not only affects efficiency but also consumes a lot of workers' time and energy. Utility Model Content

[0004] This utility model provides a plastic bottle production equipment to overcome the deficiencies in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A plastic bottle production device includes a frame with two opposing electric telescopic rods fixedly mounted horizontally on the frame. A movable block is fixedly mounted on the movable end of each electric telescopic rod. A groove is formed on the opposite side of the movable block. A mold is rotatably connected to the groove through a pin. The mold is locked by a locking mechanism. The cross-section of the mold is an equal hexagon, and each side of the module is provided with a mold groove corresponding to a plastic bottle of different sizes. A guide hole extends upward through the module from the upper part of the mold groove.

[0007] In use, the preform is placed on the corresponding mold groove. When the electric telescopic rod extends, it drives the two moving blocks to move in opposite directions, thereby driving the two molds to move in opposite directions and limiting the main preform. Then, the blow pipe passes through the guide hole and enters the corresponding preform for blow molding, thus realizing the production of plastic bottles. When different plastic bottles need to be produced, both molds are rotated so that the required mold grooves on the two molds are aligned, and the molds are locked by the locking mechanism, thus enabling the production of plastic bottles of different shapes.

[0008] Preferably, the locking mechanism includes a screw, with screw holes at the four corners of each side of the mold. The screw is threaded onto the movable block and can pass through the corresponding screw holes, engaging with them threadedly. Rotating the screw causes it to pass through the corresponding screw holes, thereby achieving a fixed connection between the screw and the corresponding mold, and consequently, a fixed connection between the movable block and the corresponding mold.

[0009] Preferably, four electric telescopic rods are provided, and the upper and lower sides of each moving block are fixedly connected to the movable end of the electric telescopic rod, while the fixed end of the electric telescopic rod is fixedly connected to the corresponding frame. This makes the moving block more stable when moving laterally.

[0010] Preferably, a crossbar is fixedly installed on the frame, and the lower part of the crossbar is supported by a triangular beam fixedly installed on the frame. A sliding groove is formed on the crossbar, and a slider slides within the groove. The slider is fixedly connected to a corresponding moving block. The support of the crossbar reduces the downward force on the electric telescopic pole, thus ensuring its long-term use.

[0011] Preferably, a guide plate is fixedly installed on the frame, and the guide plate is inclined downward from back to front. The guide plate can guide the bottles, thereby preventing the blow-molded bottles from accumulating under the frame.

[0012] The beneficial effects of this utility model are as follows: With the mold having six sides and corresponding mold grooves on each side, it is possible to process six different bottle shapes with one mold. This not only increases the range of equipment use, but also avoids the time and effort spent disassembling the mold to process different types of plastic bottles, and improves the corresponding efficiency.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A type of equipment for producing plastic bottles, such as Figures 1-3 As shown, the device includes a frame 1, on which two opposing electric telescopic rods 9 are horizontally fixed. A movable block 2 is fixedly mounted on the movable end of each electric telescopic rod 9. A groove is formed on the opposite side of the movable block 2, and a mold 3 is rotatably connected to the groove via a pin. The mold 3 is locked by a locking mechanism, which includes a screw 5. Each side of the mold 3 has four screw holes 6 at its corners. The screw 5 is threaded onto the movable block 2 and can pass through and thread-fit the corresponding screw hole 6. The mold 3 has a hexagonal cross-section, and each side of the module has a mold groove 4 corresponding to different sized plastic bottles. A guide hole extends upwards from the upper part of the mold groove 4, penetrating the module. The opposite sides of the mold 3 are located outside the movable block 2.

[0021] In use, the preform is placed on the corresponding mold groove 4 of the mold 3. When the electric telescopic rod 9 extends, it drives the two moving blocks 2 to move in opposite directions, thereby moving the two molds 3 in opposite directions and confining the preform. Then, the blow molding pipe passes through the guide hole and enters the corresponding preform for blow molding, thus producing a plastic bottle. When different plastic bottles need to be produced, both molds 3 are rotated so that the required mold grooves on the two molds 3 are aligned, and the molds 3 are locked using a locking mechanism. The rotating screw 5 passes into the corresponding screw hole 6, thereby fixing the screw 5 to the corresponding mold 3, and thus fixing the moving block 2 to the corresponding mold 3. This allows for the production of plastic bottles of different shapes.

[0022] The electric telescopic rod 9 is provided with four sections, and the upper and lower sides of each moving block 2 are fixedly connected to the movable end of the electric telescopic rod 9. The fixed end of the electric telescopic rod 9 is fixedly connected to the corresponding frame 1. This makes the moving block 2 more stable when moving laterally.

[0023] A crossbar 7 is fixedly installed on the frame 1. The lower part of the crossbar 7 is supported by a triangular beam 10 fixedly installed on the frame 1. A sliding groove is provided on the crossbar 7, and a slider 8 is slidably fitted in the groove. The slider 8 is fixedly connected to the corresponding moving block 2. The support of the crossbar 7 can reduce the downward force on the electric telescopic rod 9, thereby ensuring the long-term use of the electric telescopic rod 9.

[0024] A guide plate 11 is fixedly installed on the frame 1, and the guide plate 11 is inclined downward from back to front. The guide plate 11 can play a guiding role, thereby preventing the blow-molded bottles from accumulating under the frame 1.

[0025] The use of this application, since the mold 3 has six sides, each with a corresponding mold groove 4, enables the processing of six different bottle shapes through one mold 3. This not only increases the range of equipment use, but also avoids the time and effort spent disassembling the mold 3 to process different types of plastic bottles, and improves the corresponding efficiency.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
