Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, and more specifically, to a blow molding machine stretching mechanism with protective function. Background Technology

[0002] A blow molding machine is an automated device used to rapidly heat and blow mold plastic preforms into shape. Its working principle involves softening the preform at high temperature, then using high-pressure gas to expand it into the shape of a mold, and finally cooling and solidifying it into a high-precision, high-strength plastic bottle. However, the stretching shaft of the stretching mechanism in currently used blow molding machines is basically driven by gears on only one side during movement. This makes it prone to tilting forward or backward during movement, and the overall direction of movement is easily deviated, resulting in poor balance.

[0003] To solve the above problems, a search revealed CN221365807U, which discloses a high-speed blow molding machine stretching mechanism with close-packed heating in the field of structural telescopic. The specification states that racks and first linear guides are added to both sides of the telescopic shaft. The first linear guide ensures that the telescopic shaft can only move in the direction of the first linear guide during lifting and lowering operations, and there is no positional deviation during the movement. The first linear guide is used in conjunction with the rack on the other side, which greatly improves the balance of both sides of the telescopic shaft under the control of motor drive.

[0004] However, in practical applications, the stretching mechanism of this blow molding machine still has certain limitations. Although the above-mentioned technical solution uses sliding fit structures such as linear guides to reduce positional misalignment, and can reduce friction and ensure smooth movement by applying lubricating oil, thereby avoiding problems such as lifting jamming and shortened equipment life caused by rigid friction, the light base oil component of traditional lubricating oil is highly volatile under high-temperature conditions. This not only causes a rapid decrease in the amount of lubricating oil, but also leads to an imbalance in the additive ratio, thereby weakening the lubrication effect and requiring frequent oil replenishment to maintain normal operation. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a blow molding machine stretching mechanism with protective function, so as to solve the problem that in the prior art, some blow molding machine stretching mechanisms use linear guides to reduce offset, but high temperature causes lubricating oil to evaporate and additives to become unbalanced, requiring frequent oil replenishment, which affects the lubrication effect and service life.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a blow molding machine stretching mechanism with protective function, comprising...

[0007] A substrate has a telescopic drive mechanism in its middle. The bottom end of the telescopic drive mechanism is connected to a movable plate. The middle of the movable plate has a plurality of air blowing pipe bodies, and the outer surfaces of the plurality of air blowing pipe bodies are slidably installed with the inner surface of the bottom of the substrate. Both ends of the movable plate are fixedly installed with sliders. The middle of the sliders is slidably installed with guide rails. The surface of the guide rails is fixedly installed with the side of the substrate. The top of the guide rails is provided with a self-lubricating mechanism.

[0008] The self-lubricating mechanism includes an oil tank, a connecting pipe fixedly installed at the bottom of the oil tank, an oil outlet pipe slidably installed on the inner surface of the connecting pipe, a U-shaped frame fixedly sleeved on the outer surface of the bottom end of the oil outlet pipe, and a spring fixedly connected to the top of both ends of the U-shaped frame, with the top of the spring fixedly connected to the bottom of the oil tank.

[0009] The oil tank has an injection port at the top, and a cover plate is threaded onto the outer surface of the injection port. The top of the oil outlet pipe is sealed, and a through hole is provided on the side wall of the top.

[0010] The telescopic drive mechanism includes a motor, which is fixedly mounted on the surface of one side of the back of the substrate. A gear is fixedly sleeved on the output end of the motor. A rack meshes with the outer edge of the gear. A guide rail is fixedly mounted on the side of the rack away from the gear. A slider is slidably mounted on the outer surface of the guide rail. The surface of the slider is fixedly mounted to the surface of one side of the front of the substrate. A connecting block is fixedly mounted on the bottom end of the rack. The bottom of the connecting block is fixedly mounted to the upper surface of the middle of the movable plate.

[0011] The fuel tank has a quick-release installation mechanism on one side of its back.

[0012] The quick-release installation mechanism includes a slide rail, the side of which is fixedly installed to the surface of the oil tank. A fitting plate is slidably installed on the inner surface of the middle part of the slide rail. The fitting plate is fixedly installed on the surface of the base plate. A frame is provided at the top of the fitting plate. The bottom of the frame is fixedly installed to the upper surface of the base plate. A second spring is provided in the middle of the frame. Both ends of the second spring are connected to L-shaped blocks. The outer surface of the L-shaped blocks is slidably installed to the inner surface of the end of the frame. A misalignment block is fixedly installed on the side of the bottom of the L-shaped blocks. Connecting ropes are connected to the surfaces of the two L-shaped blocks that are close to each other at their top ends. Adjusting blocks are fixedly connected to the ends of the two connecting ropes that are close to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above scheme, the self-lubricating mechanism achieves automatic lubrication through the movement of slider one. When slider one slides along guide rail one to its highest point, it pushes the U-shaped frame upward, causing the oil outlet pipe to slide upward within the connecting pipe, while simultaneously compressing spring one. When the opening at the top of the oil outlet pipe enters the oil tank, lubricating oil flows into the oil outlet pipe through the opening, and then drips onto the top of guide rail one and the top of slider one, where it is evenly coated on the guide rail surface under the action of gravity or the movement of the slider. When slider one descends, the elastic restoring action of spring one resets the oil outlet pipe and other components, automatically cutting off the lubricating oil supply. This design achieves automatic lubrication synchronized with the movement of the slider, effectively improving the smoothness of the operation of guide rail one and slider one, reducing wear, and extending the service life of the equipment.

[0015] In the above design, the quick-release installation mechanism makes the maintenance of the self-lubricating mechanism more convenient. During disassembly, pulling the adjusting block upwards causes the two L-shaped blocks to slide along the frame and move closer together via the connecting rope, compressing the second spring and aligning the misaligned block with the mating plate. At this point, the oil tank, along with the slide rail, can be pulled out from the tracks of the mating plate and misaligned block for easy cleaning, inspection, or replacement of parts. This quick-release structure significantly improves the ease of maintenance and practicality of the device. Attached Figure Description

Detailed Implementation

[0023] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a blow molding machine stretching mechanism with protective function, including...

[0024] The substrate 1 has a telescopic drive mechanism 2 in the middle and a movable plate 3 connected to the bottom of the telescopic drive mechanism 2.

The surface of the guide rails 5 is fixedly installed with the side of the substrate 1. The top of the guide rails 5 is provided with a self-lubricating mechanism 7.

[0025] The self-lubricating mechanism 7 includes an oil tank 70, a connecting pipe 71 fixedly installed at the bottom of the oil tank 70, an oil outlet pipe 72 slidably installed on the inner surface of the connecting pipe 71, a U-shaped frame 73 fixedly sleeved on the outer surface of the bottom end of the oil outlet pipe 72, and springs 74 fixedly connected to the top of both ends of the U-shaped frame 73, with the top of the springs 74 fixedly connected to the bottom of the oil tank 70.

[0026] The oil tank 70 has an injection port 75 at the top, and a cover plate is threaded onto the outer surface of the top of the injection port 75. The top of the oil outlet pipe 72 is sealed, and a through hole is opened on the side wall of the top.

[0027] The telescopic drive mechanism 2 includes a motor 20, which is fixedly installed on the surface of one side of the back of the base plate 1. A gear 21 is fixedly sleeved at the output end of the motor 20. A rack 22 meshes with the outer edge of the gear 21. A guide rail 23 is fixedly installed on the side of the rack 22 away from the gear 21. A slider 24 is slidably installed on the outer surface of the guide rail 23. The surface of the slider 24 is fixedly installed on the surface of one side of the front of the base plate 1. A connecting block 25 is fixedly installed at the bottom end of the rack 22. The bottom of the connecting block 25 is fixedly installed on the upper surface of the middle part of the movable plate 3.

[0028] The fuel tank 70 has a quick-release installation mechanism 8 on one side of its back.

[0029] The quick-release installation mechanism 8 includes a slide rail 80, the side of which is fixedly installed to the surface of the oil tank 70. A fitting plate 81 is slidably installed on the inner surface of the middle part of the slide rail 80. The fitting plate 81 is fixedly installed on the surface of the base plate 1. A frame 82 is provided at the top of the fitting plate 81. The bottom of the frame 82 is fixedly installed to the upper surface of the base plate 1. A spring 83 is provided in the middle of the frame 82. Both ends of the spring 83 are connected to L-shaped blocks 84. The outer surface of the L-shaped blocks 84 is slidably installed to the inner surface of the end of the frame 82. A misalignment block 85 is fixedly installed on the side of the bottom of the L-shaped blocks 84. Connecting ropes 87 are connected to the surfaces of the tops of the two L-shaped blocks 84 that are close to each other. Adjusting blocks 86 are fixedly connected to the ends of the two connecting ropes 87 that are close to each other.

[0030] By setting a self-lubricating mechanism 7 and a quick-release mounting mechanism 8, a set of self-lubricating mechanisms 7 and quick-release mounting mechanisms 8 are also installed on the top of the rack 22 by a vertical plate fixed in the middle of the base plate 1. The bottom of the set of self-lubricating mechanisms 7 is a T-shaped plate. The oil outlet pipe 72 can be lifted and pressed by a protruding post fixed to the top of the rack 22.

[0031] The working process of this utility model is as follows:

[0032] During the blow molding operation, the control motor 20 drives the gear 21 connected to the output end to rotate, causing the meshing rack 22 to move up and down, driving the guide rail 23 mounted on its side to slide along the inner surface of the slider 24. Through the connecting block 25, the connected movable plate 3 pulls the slider 6 connected at both ends to slide along the surface of the guide rail 5. Several blowing pipe bodies 4 installed in the middle of the movable plate 3 are pulled to move up and down, probing into the base material to perform the blow molding operation. With the cooperation of the guide rail 5, slider 6 and guide rail 23 and slider 24, the stability is improved.

[0033] Furthermore, each time slider 6 slides up to its highest point along the surface of guide rail 5, slider 6 pushes the U-shaped frame 73 located on the top side of the substrate 1 upwards, causing the oil outlet pipe 72, which is sleeved in the middle, to slide upwards along the inner surface of the connecting pipe 71. This compresses the spring 74 located at the junction of the bottom of the oil tank 70 and the top of the U-shaped frame 73. When the opening at the top of the oil outlet pipe 72 extends into the oil tank 70, the lubricating oil inside the oil tank 70 can flow into the oil outlet pipe 72 from the opening, and then drip down the oil outlet pipe 72 onto the guide rail 5. The top of rail 5 and the top of slider 6 are coated with oil under the action of gravity or the movement of slider 6, achieving lubrication treatment at the structural connection. After slider 6 descends, it is elastically reset by spring 74, and the oil outlet pipe 72 and other structures will reset, and the lubricating oil will no longer flow out. Thus, the self-lubricating mechanism 7 is used to configure the movement of slider 6 to automatically supply lubricating oil, effectively improving the smoothness of operation between rail 5, slider 6 and other structures, reducing rigid damage, providing protection for the equipment and extending its service life.

[0034] The self-lubricating mechanism 7 is installed using the quick-release installation mechanism 8, which facilitates disassembly and makes maintenance and cleaning easier. During disassembly, the adjusting block 86 is pulled upwards first, causing the two L-shaped blocks 84 connected to the adjusting block 86 by the connecting rope 87 to slide along the inner surfaces of both ends of the frame 82 and move closer to each other, squeezing the spring 83 between them. At this time, the misaligned block 85 connected to the bottom of the L-shaped block 84 is adjusted from being intersected with the fitting plate 81 to being in the same straight line as the fitting plate 81. Then, the oil tank 70 is moved upwards, and the slide rail 80 connected to its surface can slide out along the surface of the fitting plate 81 and the misaligned block 85, thus facilitating disassembly or installation, and making it easier to inspect and replace parts or clean the inside of the oil tank 70, thereby improving the practicality of the device.
