Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, and in particular to a lifting platform device for an all-electric blow molding machine. Background Technology

[0002] Traditional blow molding machines' lifting platforms are designed for low- to medium-speed production scenarios, such as... Figure 1 As shown, chain drive is typically used for lifting. However, this technology has the following drawbacks: 1. Insufficient dynamic performance: transmission lag, vibration, and start-stop impact. The multi-link meshing of the chain causes a delay in power transmission at the driven end, leading to mold positioning deviation during high-speed lifting, resulting in misalignment of the bottle neck thread forming and increasing the scrap rate. When the motor stops suddenly, the chain bears impact loads, which accelerates guide rail wear and shortens the equipment's service life. 2. Precision control bottleneck: significant cumulative errors, sensitivity to thermal deformation, and the tendency to manufacture tolerances in multi-stage sprocket drives, leading to overall straightness deviations in the transmission system. Such deviations cannot meet the precision machining requirements of PET bottle neck threads. In addition, chain materials (such as 45 steel) have the characteristic of expanding at high temperatures. In the working conditions of a blow molding workshop, the chain is stretched by heat, requiring frequent adjustments to the tensioning device to maintain accuracy. 3. Limited chain reliability: there is a risk of chain breakage and foreign object intrusion. The chain link pin bearings have limited resistance to alternating shear stress. Under low-speed, high-torque conditions, the probability of chain wear and breakage will increase significantly after long-term use. In addition, the open chain structure easily attracts plastic debris, causing chain links to jam, and the cleaning process is time-consuming and pollutes the production environment.

[0003] Therefore, when there are high requirements for ease of maintenance, quiet operation, transmission accuracy, or environmental adaptability, the current chain drive needs to be improved. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a lifting platform device for an all-electric blow molding machine.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A lifting platform device for a fully electric blow molding machine includes a blow molding machine base and a lifting platform. The lifting platform is disposed above the blow molding machine base. Multiple columns are vertically arranged on the blow molding machine base. A worm gear screw lifting assembly is installed on the top of the multiple columns. The worm gear screw lifting assembly drives the lifting platform to move up and down.

[0007] Furthermore, the worm gear screw jack assembly includes a first worm gear screw jack, a second worm gear screw jack, a geared motor, a first drive shaft, and a second drive shaft. Four columns are vertically arranged on the blow molding machine base in a rectangular configuration. A crossbeam is fixedly connected between every two closely spaced columns. The first worm gear screw jack is fixedly installed on the top of each of the two closely spaced columns. The first worm gear screw jack has a first input end and a second input end that are perpendicular to each other. The second worm gear screw jack is fixedly installed on the top of the other two columns. The lifting platform has an independent input end, and a reduction motor is arranged between the two first worm gear screw jacks. The reduction motor is fixed on the crossbeam and has two coaxially arranged output ends. The two output ends of the reduction motor are respectively connected to the first input ends of the two first worm gear screw jacks through the first transmission shaft. The second input ends of the two first worm gear screw jacks are respectively connected to the independent input ends of the two second worm gear screw jacks through the second transmission shaft. The output screws of the first and second worm gear screw jacks are rotatably mounted on the lifting platform.

[0008] Furthermore, the column is a hollow cylindrical shape, and the lifting screws of the first and second worm gear screw jacks are respectively located inside the corresponding column.

[0009] The beneficial effects of this utility model are as follows: Replacing chain drive with a worm gear screw lifting assembly significantly improves safety, eliminates the risk of chain breakage, and automatically locks in case of power failure, ensuring the safety of operators and equipment; the axially integrated design of the worm gear screw reduces the size of the transmission unit, adapting to the multi-station layout requirements of the narrow space in a blow molding machine; the worm gear screw lifting assembly has stronger operational stability, no vibration or noise, and precise control of lifting height, improving bottle forming accuracy; no need to lubricate the chain or replace vulnerable parts, resulting in a low failure rate over long-term use and significantly reduced maintenance costs; compared to chain drive, the worm gear screw lifting assembly is better suited to harsh working conditions and is suitable for the high-temperature and high-pressure production environment of blow molding machines.

[0015] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] like Figures 2-4 As shown, a lifting platform device for a fully electric blow molding machine includes a blow molding machine base 1 and a lifting platform 2. The lifting platform 2 is positioned above the blow molding machine base 1. Four columns 3 are vertically mounted on the blow molding machine base 1 in a rectangular arrangement. A crossbeam 4 is fixedly connected between every two closely spaced columns 3. A first worm gear screw jack 5 is fixedly installed on the top of the two columns 3 on the right side of the blow molding machine base 1. The first worm gear screw jack 5 has a first input end 51 and a second input end 52 that are perpendicular to each other. A second worm gear screw jack 6 is fixedly installed on the top of the two columns 3 on the left side of the blow molding machine base 1. The second worm gear screw jack 6 has an independent input end 61. A reduction motor 7 is arranged between the two first worm gear screw jacks 5 and is fixed to the blow molding machine base 1. On the right-side crossbeam 4, the geared motor 7 has two coaxially arranged output ends 71. The two output ends 71 ​​of the geared motor 7 are connected to the first input ends 51 of the two first worm gear screw jacks 5 through a first drive shaft 8. The second input ends 52 of the two first worm gear screw jacks 5 are connected to the independent input ends 61 of the two second worm gear screw jacks 6 through a second drive shaft 9. The output screws of the first worm gear screw jacks 5 and the second worm gear screw jacks 6 are rotatably installed at the bottom of the lifting platform 2. Specifically, the top of the output screws of the first worm gear screw jacks 5 and the second worm gear screw jacks 6 are respectively rotatably sleeved with a first flange sleeve 53 and a second flange sleeve 62. The first flange sleeve 53 and the second flange sleeve 62 are both fixed to the bottom of the lifting platform 2 by screws.

[0017] In actual operation, the worm wheels of the two first worm screw jacks 5 are driven to rotate by the geared motor 7. The first worm screw jacks 5 transmit power to the second worm screw jacks 6 through the second transmission shaft 9, so that the screws of the two first worm screw jacks 5 and the two second worm screw jacks 6 rotate synchronously, thereby driving the lifting platform 2 to rise and fall.

[0018] In this embodiment, the column 3 is a hollow square tube shape. The output screws of the first worm gear screw jack 5 and the second worm gear screw jack 6 are respectively located inside the corresponding column 3. This design hides the screws of the worm gear screw jack inside the column 3, making it more concise and aesthetically pleasing.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
