Description

Technical Field

[0001] This utility model relates to the field of bottle making machine technology, specifically a rotary bottle making machine lifting mechanism. Background Technology

[0002] In the glass bottle manufacturing industry, the lifting mechanism of the bottle-making machine plays a crucial role. It is responsible for adjusting the height of the mold or preform to ensure that bottles with stable shape and high quality can be obtained during the blowing process. However, the existing bottle-making machine lifting mechanism has the problem of inconvenient adjustment.

[0003] Chinese patent discloses a rotary bottle-making machine lifting mechanism (authorization announcement number CN204897702U). This patented technology includes a lifting plate and a base. The lower end of the lifting plate is fitted inside the base, and an adjusting handwheel is fitted at the bottom of the base. The adjusting handwheel is connected to an adjusting rod, which extends into the base and is threadedly connected to the lifting plate. A bearing cover plate is connected to the upper end of the base, and the lower end of the lifting plate passes through the bearing cover plate and extends into the base. The lifting plate has a keyway, and the bearing cover plate has protrusions that match the keyway. This invention integrates speed regulation and lifting, offering good adjustment feel and convenient adjustment to meet the needs of different bottle heights.

[0004] However, it has certain drawbacks: during the production process, the adjusting rod is prone to rotation due to accidental contact or vibration during long-term operation of the equipment. This will cause the lifting plate connected to it to rise or fall, thereby changing the height of the turntable and making it impossible for the bottle making machine to maintain the set working parameters. Utility Model Content

[0005] The purpose of this utility model is to provide a rotary bottle making machine lifting mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotary bottle making machine lifting mechanism includes a base, a base plate is fixedly connected to the upper end of the outer surface of the base, and a bearing sleeve is fixedly connected to the lower end of the base. An adjusting rod is installed inside the bearing sleeve, and a lifting component is provided inside the base.

[0008] The front surface of the base is provided with a positioning mechanism, which includes an L-shaped plate. A rotating tube is rotatably connected through the lower end of the L-shaped plate. A rotating rod is threadedly connected inside the rotating tube. A positioning block is fixed to the rear end of the rotating rod. A positioning rod is fixed to the upper end of the front surface of the positioning block. A ratchet is fixed to the outside of the rotating tube in front of the L-shaped plate. A limit mechanism is provided on the front surface of the L-shaped plate above the rotating tube.

[0009] As a further embodiment of this utility model: the lifting component includes an adjusting tube, with fixing rods fixedly connected to both the left and right surfaces of the adjusting tube, and a fixing disc fixedly connected to the upper end of the adjusting tube.

[0010] As a further embodiment of this utility model: the limiting mechanism includes a pawl, the right end of which is rotatably connected to a limiting rod, and a spring is fixedly connected to the upper surface of the pawl, with a limiting block fixedly connected to the upper end of the spring.

[0011] As a further embodiment of this utility model: the upper end of the L-shaped plate is fixed to the front surface of the base, the positioning block is directly opposite the adjusting rod, and the positioning rod movably passes through the L-shaped plate.

[0012] As a further embodiment of this utility model: the adjusting rod is threadedly connected to the inside of the adjusting tube, and both the adjusting tube and the fixing rod are slidably connected to the base.

[0013] As a further embodiment of this utility model: the pawl is attached to the ratchet, and the rear ends of the limiting rod and the limiting block are both fixed to the front surface of the L-shaped plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses the rotating adjusting rod to raise and lower the adjusting tube connected to it by thread, thereby driving the turntable of the bottle making machine to rise and fall through the fixed plate, which is suitable for glass bottles of different heights.

[0016] 2. This utility model is equipped with a positioning mechanism. Rotating the rotating tube in the positioning mechanism counterclockwise causes the rotating rod to move backward, which in turn drives the positioning block to press the adjusting rod. This prevents the adjusting rod from rotating due to accidental contact or vibration during equipment operation, thus ensuring that the height of the turntable remains unchanged after adjustment. The pawl engages with the ratchet, preventing the rotating tube from rotating clockwise, which in turn ensures that the positioning block always presses the adjusting rod, further improving the stability of the adjusting rod.

Detailed Implementation

[0021] Please see Figure 1 In this embodiment of the utility model, a rotary bottle making machine lifting mechanism includes a base 1, a base plate 2 is fixedly connected to the upper end of the outer surface of the base 1, and a bearing sleeve 3 is fixedly connected to the lower end of the base 1. An adjusting rod 4 is installed inside the bearing sleeve 3. A lifting component 5 is provided inside the base 1. The lifting component 5 includes an adjusting tube 6. The adjusting rod 4 is threadedly connected to the inside of the adjusting tube 6. Fixed rods 7 are fixedly connected to both the left and right surfaces of the adjusting tube 6. The adjusting tube 6 and the fixed rods 7 are slidably connected to the base 1. A fixed plate 8 is fixedly connected to the upper end of the adjusting tube 6.

[0022] The entire mechanism is fixed to the rotary bottle-making machine via base plate 2;

[0023] Fixed plate 8 is fixed together with the turntable;

[0024] The bearing sleeve 3 includes a bearing housing and a bearing inside the bearing housing. The adjusting rod 4 is fixed in the inner ring of the bearing (the inner ring and the outer ring rotate relative to each other). Therefore, the adjusting rod 4 can rotate through the bearing, that is, the adjusting rod 4 and the bearing sleeve 3 rotate relative to each other.

[0025] Rotating the adjusting rod 4 will cause the adjusting tube 6 to raise or lower the fixed plate 8, which in turn raises or lowers the turntable of the bottle making machine, making the turntable suitable for glass bottles of different heights.

[0026] A rotating wheel is fixed to the lower end of the adjusting rod 4 to facilitate the rotation of the adjusting rod 4.

[0027] exist Figure 1 and Figure 2 In the middle: A positioning mechanism 9 is provided on the front surface of the base 1. The positioning mechanism 9 includes an L-shaped plate 10. The upper end of the L-shaped plate 10 is fixed to the front surface of the base 1. A rotating tube 11 is rotatably connected through the lower end of the L-shaped plate 10. A rotating rod 12 is threadedly connected inside the rotating tube 11. A positioning block 13 is fixed to the rear end of the rotating rod 12. A positioning rod 14 is fixed to the upper end of the front surface of the positioning block 13. The positioning block 13 is directly opposite the adjusting rod 4. The positioning rod 14 movably passes through the L-shaped plate 10.

[0028] Clamping the rotating tube 11 with pliers and rotating it counterclockwise will cause the rotating rod 12 to move backward, thereby causing the positioning block 13 to press the adjusting rod 4, preventing the adjusting rod 4 from rotating due to accidental contact or vibration during equipment operation, which would cause the height of the turntable to change.

[0029] exist Figures 1-3 In the middle: a ratchet 15 is fixedly connected to the outside of the rotating tube 11 in front of the L-shaped plate 10. A limiting mechanism 16 is provided on the front surface of the L-shaped plate 10 above the rotating tube 11. The limiting mechanism 16 includes a pawl 17, which is attached to the ratchet 15. A limiting rod 18 is rotatably connected through the right end of the pawl 17. A spring 19 is fixedly connected to the upper surface of the pawl 17. A limiting block 20 is fixedly connected to the upper end of the spring 19. The rear ends of the limiting rod 18 and the limiting block 20 are both fixedly connected to the front surface of the L-shaped plate 10.

[0030] The pawl 17 engages with the ratchet 15, allowing the rotating tube 11 to rotate counterclockwise but not clockwise, thus ensuring that the positioning block 13 can always press the adjusting rod 4.

[0031] After pulling the pawl 17 away from the ratchet 15, the rotating tube 11 can be rotated clockwise to move the rotating rod 12 forward.

[0032] The working principle of this utility model is as follows: The entire lifting mechanism is fixed to the bottle-making machine via the base plate 2, and the turntable is fixed to the fixed plate 8. Before use, the adjusting rod 4 is rotated as needed, and the adjusting tube 6 connected to it will drive the fixed plate 8 to rise and fall, thereby adjusting the height of the bottle-making machine turntable. After adjustment, the rotating tube 11 is rotated counterclockwise to drive the rotating rod 12 to move backward, thereby driving the positioning block 13 to move backward until it presses against the adjusting rod 4, so that the adjusting rod 4 cannot be rotated by hand. The next time the adjusting rod 4 needs to be rotated, the pawl 17 is pulled away from the ratchet 15, and then the rotating tube 11 is rotated clockwise to drive the rotating rod 12 to move forward, so that the positioning block 13 is away from the adjusting rod 4, and then the adjusting rod 4 can be rotated.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
