Detailed Description
The invention is described in further detail below with reference to the figures and preferred embodiments.
As shown in fig. 1 and 2, the driving device for a stretching rod of a bottle blowing machine includes: installing support 1, the vertical two guide rails 2 that are provided with on installing support 1, two guide rails 2 are the mutual interval and parallel and set up, all are provided with slider 3 on every guide rail 2, and the equal fixedly connected with rack of slider 3 on every guide rail 2. In order to improve the running stability of the rack in the embodiment, each guide rail 2 is provided with a pair of sliding blocks 3, and each pair of sliding blocks 3 is fixedly connected with the upper end and the lower end of the corresponding rack. The two racks are respectively a driving rack 4 and a driven rack 5, the stretching rod 6 is fixedly connected to the lower end portion of the driven rack 5, specifically, the upper end portion of the stretching rod 6 is clamped by a clamping block 61, and the clamping block 6 is fixed to the lower end portion of the driven rack 5 through a bolt. The stretching rod 6 is fixed with the driven rack 5 by adopting the structure, and has the advantages that: the installation height of the stretching rod 6 can be adjusted conveniently.
The driving rack 4 is connected with a driving part, the driving part is a cylinder 7, the cylinder 7 is installed on the installation support 1, a piston rod of the cylinder 7 is connected with the driving rack 4, and the piston rod of the cylinder 7 extends downwards to drive the driving rack 4 to move downwards. In this embodiment, the mounting bracket 1 below the driving rack 4 is provided with a limit stop 9, and the limit stop 9 can stop the slider 3 at the lower end of the driving rack 4.
A speed change mechanism is arranged on the mounting bracket 1 between the driving rack 4 and the driven rack 5. The speed change mechanism comprises: the mounting base 8 is provided with a first mounting shaft 81 and a second mounting shaft 82 on the mounting base 8, a first gear 811 is mounted on the first mounting shaft 81, a double-row gear of an integrated structure is mounted on the second mounting shaft 82, the double-row gear sequentially comprises a second gear 821 and a third gear 822 from inside to outside, the diameter of the first gear 811 is smaller than that of the second gear 821, and the first gear 811 and the second gear 821 are meshed with each other. The mounting seat 8 can be installed on the mounting bracket 1 in a forward direction or a reverse direction, in this embodiment, the upper end portion and the lower end portion of the mounting seat 8 are respectively and symmetrically provided with a pair of bolt holes 800, and the mounting seat 8 is detachably and fixedly installed on the mounting bracket 1 through bolts. As shown in fig. 1, when the mounting seat 8 is mounted on the mounting bracket 1 in the forward direction, the first gear 811 is engaged with the driving rack 4, and the third gear 822 is engaged with the driven rack 5; as shown in fig. 3 and 4, when the mount is reversely mounted on the mounting bracket 1, the third gear 822 is engaged with the driving rack 4, and the first gear 811 is engaged with the driven rack 5. Under the driving of a driving part, namely an air cylinder 7, the driving rack 4 moves downwards to drive the driven rack 5 to drive the stretching rod 6 to move downwards, so that the bottle blank is stretched axially.
The working principle is as follows: when the forward installation of mount pad 8, the piston rod of cylinder 7 stretches out downwards and drives initiative rack 4 downstream, and initiative rack 4 drives first gear 811 and rotates, and first gear 811 orders about second gear 821 and rotates, and third gear 822 then follows and rotates together, and third gear 822 then can drive driven rack 5 downstream, and tensile pole 6 will downstream like this to the bottom that downwards supports and presses the bottle base makes the bottle base axial obtain stretching. When the slide block 3 at the lower end of the driving rack 4 is abutted against the limiting block 9, the stretching rod 6 moves downwards to the limit position. Since the diameter of the first gear 811 is smaller than the diameter of the second gear 821, the driven rack 5 moves downward at a lower speed than the driving rack 4 when the mount 8 is mounted in the forward direction. When the reverse installation of mount pad 8, the piston rod of cylinder 7 stretches out downwards, and the drive is initiative rack 4 downstream, and initiative rack 4 drives third gear 822 and rotates, and second gear 821 then follows and rotates together, and second gear 821 orders about first gear 811 and rotates, and first gear 811 then can drive driven rack 5 downstream, and tensile pole 6 will downstream like this to the bottom that downwards supports and presses the bottle base makes the bottle base axial obtain stretching. When the mounting seat 8 is reversely mounted, the downward movement speed of the driven rack 5 is greater than that of the driving rack 4.
From the above, the forward or reverse installation of the installation seat 8 can be used to adjust the downward movement speed of the driven rack 5, i.e. the downward stretching speed of the bottle preform by the stretching rod 6, so that the stretching speed of the stretching rod 6 can be adapted to different bottle types. Therefore, the driving device of the stretching rod in the bottle blowing machine can be suitable for blowing different bottle types, the mounting seat can be installed in the forward direction or the reverse direction according to the bottle type requirements in the actual production process, and the speed of the stretching rod 6 can be adjusted very conveniently. In addition, the whole stretching rod driving device has low noise in the action process, which greatly improves the working environment of workers.
