Description

Technical Field

[0001] The utility model relates to the field of glass bottle manufacturing, in particular to a glass tube dropping buffer and precise height positioning device. Background Art

[0002] When a controlled bottle manufacturing machine places a glass tube, there are two common methods. One is to use a manipulator to place the glass tube into the bottle manufacturing machine, and the other is to use a push tube device to push the glass tube placed in the glass tube supporting frame into the bottle manufacturing machine. Under the action of gravity, the glass tube falls into the designated position. However, when using a special manipulator to place the glass tube in the bottle manufacturing machine, there is a problem that due to the inaccurate initial position of the glass tube, the positioning of the glass tube in the bottle manufacturing machine is also inaccurate. When using the push tube method, since the glass tube may bounce during the falling process and impact with the buffer device, there are also situations where the glass tube breaks due to the impact with the buffer device. Neither method can accurately position the glass tube, and thus the front section of the glass tube cannot be made into a bottle, resulting in waste of the glass tube and affecting the utilization rate of the glass tube. Summary of the Invention

[0003] In order to overcome the above deficiencies in technology, the utility model provides a glass tube dropping buffer and precise height positioning device that can accurately place the glass tube at a specified height and prevent the glass tube from being damaged.

[0004] The technical solution adopted by the utility model to overcome its technical problems is as follows:

[0005] A glass tube dropping buffer and precise height positioning device, comprising:

[0006] A bottom plate, installed on the controlled bottle manufacturing machine;

[0007] A machine base, installed at the upper end of the bottom plate through a guiding mechanism, and the machine base moves relative to the bottom plate in the vertical direction through the guiding mechanism;

[0008] A height adjusting mechanism, used to drive the machine base to move up and down relative to the bottom plate;

[0009] A sliding table cylinder I, installed above the machine base, and a connecting plate is installed on its sliding platform;

[0010] A rotating plate, the middle part of the lower end of which is rotatably installed on the connecting plate through a rotating shaft, and an elastic plate is installed on the outer side of the upper end of the rotating plate;

[0011] A buffer mechanism, arranged on the connecting plate. After the sliding table cylinder I drives the rotating plate to move outward relative to the controlled bottle manufacturing machine, the glass tube falls onto the elastic plate, and when the rotating plate rotates, the buffer mechanism absorbs the impact force; and

[0012] A sliding table cylinder II, installed above the machine base, and a rigid plate is installed on its sliding platform through screws, and the upper end surface of the rigid plate is located below the upper end surface of the elastic plate.

[0013] Further, the guiding mechanism includes an optical axis vertically installed at the lower end of the machine base and a linear bearing installed on the bottom plate. The axis of the optical axis is arranged vertically, and the optical axis is inserted into the linear bearing.

[0014] Further, the height adjusting mechanism includes a support I installed at the upper end of the bottom plate and a support II installed at the lower end of the machine base. Screw holes are arranged vertically in both the support I and the support II. One end of the left - right screw is screwed into the screw hole of the support I, and the other end is screwed into the screw hole of the support II.

[0015] For the convenience of operation, a handwheel is arranged on the left - right screw.

[0016] Further, the buffering mechanism includes a hydraulic buffer installed on the connecting plate.

[0017] Further, the elastic plate is made of polyurethane or polytetrafluoroethylene material.

[0018] Further, the rigid plate is made of metal material.

[0019] For the convenience of resetting, a spring is further included. The upper end of the spring is connected to the rotating plate, and the lower end is connected to the connecting plate. When the spring is in a free state, the rotating plate is in a horizontal state.

[0020] For achieving limiting, a nut I is further included and arranged outside the upper end of the connecting plate, and a nut II is arranged inside the upper end of the connecting plate. Bolt I is screwed into the nut I, and bolt II is screwed into the nut II. When the rotating plate is in a horizontal state, its lower end surface contacts the top of bolt II. When the rotating plate rotates to trigger the hydraulic buffer, its lower end surface contacts the top of bolt I.

[0021] The beneficial effects of the present utility model are as follows: When the glass tube drops to the elastic plate, since the elastic plate is made of a flexible material and the connecting plate rotates through the rotating shaft and the buffering mechanism is used to absorb the impact force of the falling glass tube, the glass tube can be effectively prevented from being damaged. Then, after the upper clamp of the glass tube manufacturing machine clamps and fixes the glass tube, the glass tube manufacturing machine rotates until the glass tube is located directly above the rigid plate. Since the rigid plate is located below the elastic plate, after the upper clamp is released, the glass tube falls onto the rigid plate, and the height of the glass tube is fixed by adjusting the height adjusting mechanism. The upper clamp of the glass tube manufacturing machine clamps and fixes the glass tube again, and then the glass tube manufacturing machine rotates to the processing area, and the glass tube with a fixed height can be processed. The buffering during the falling of the glass tube and the precise positioning of the initial position of the glass tube are realized. Description of the Drawings

Specific embodiments

[0026] The following further describes the present utility model with reference to the attached Figure 1 , attached Figure 2 , attached Figure 3 drawings.

[0027] A glass tube drop tube buffering and precise height positioning device, comprising: a bottom plate 1, installed on a control bottle manufacturing machine; a machine base 2, installed at the upper end of the bottom plate 1 through a guiding mechanism, and the machine base 2 moves relative to the bottom plate 1 in the vertical direction through the guiding mechanism; a height adjusting mechanism, used to drive the machine base 2 to move up and down relative to the bottom plate 1; a slide cylinder I 9, installed above the machine base 2, and a connecting plate 11 is installed on its sliding platform; a rotating plate 10, the middle part of the lower end of which is rotatably installed on the connecting plate 11 through a rotating shaft 12, and an elastic plate 13 is installed on the outer side of the upper end of the rotating plate 10; a buffering mechanism, arranged on the connecting plate 11, after the slide cylinder I 9 drives the rotating plate 10 to move outward relative to the control bottle manufacturing machine, the glass tube falls onto the elastic plate 13, and when the rotating plate 10 rotates, the impact force is absorbed through the buffering mechanism; and a slide cylinder II 15, installed above the machine base 2, and a rigid plate 16 is installed on its sliding platform through a screw 17, and the upper end surface of the rigid plate 16 is located below the upper end surface of the elastic plate 13. The pipe holding frame of the control bottle manufacturing machine rotates to rotate the glass tube to be processed to directly above the elastic plate 13, and the pipe pushing device pushes down the glass tube placed in the pipe holding frame, and the glass tube falls to the elastic plate 13. Since the elastic plate 13 is made of a flexible material and the connecting plate 11 rotates through the rotating shaft 12 and the buffering mechanism absorbs the impact force of the glass tube falling, the glass tube can be effectively prevented from being damaged. Then, after the upper clamp of the control bottle manufacturing machine clamps and fixes the glass tube, the control bottle manufacturing machine rotates until the glass tube is directly above the rigid plate 16. Since the rigid plate 16 is located below the elastic plate 13, after the upper clamp is released, the glass tube falls onto the rigid plate 16, and the height of the glass tube is determined by adjusting the height adjusting mechanism. The upper clamp of the control bottle manufacturing machine clamps and fixes the glass tube again, and then the control bottle manufacturing machine rotates to the processing area to process the glass tube with a determined height. The buffering when the glass tube falls and the precise positioning of the initial position of the glass tube are realized. The height of the machine base 2 can be adjusted through the height adjusting mechanism, so that the entire device can adjust the height according to the glass tube specifications to adapt to the manufacture of control bottles of different specifications.

[0028] In an embodiment of the present invention, the guiding mechanism includes an optical axis 4 installed vertically at the lower end of the machine base 2 and a linear bearing 3 installed on the bottom plate 1. The axis of the optical axis 4 is arranged vertically, and the optical axis 4 is inserted into the linear bearing 3. When the machine base 2 moves up and down, it can move smoothly under the guidance of the optical axis 4 in the linear bearing 3, with a simple structure and reliable operation.

[0029] In an embodiment of the present utility model, the height adjustment mechanism includes a support I 5 installed at the upper end of the bottom plate 1 and a support II 6 installed at the lower end of the machine base 2. Screw holes are provided vertically in both the support I 5 and the support II 6. One end of the positive and negative lead screw 7 is screwed into the screw hole of the support I 5, and the other end is screwed into the screw hole of the support II 6. When the positive and negative lead screw 7 is rotated, since the thread directions at the upper and lower ends of the positive and negative lead screw 7 are opposite, when it rotates in the screw holes of the support I 5 and the support II 6, the machine base 2 will move up and down under the guidance of the guiding mechanism. In this embodiment, a hand wheel 8 is provided on the positive and negative lead screw 7. By providing the hand wheel 8, it is convenient to drive the rotation of the positive and negative lead screw 7, further improving the convenience of operation.

[0030] In an embodiment of the present utility model, the above-mentioned buffer mechanism includes a hydraulic buffer 14 installed on the connecting plate 11. When the glass tube falls onto the elastic plate 13, the rotating plate 10 rotates, and after it is disengaged from the hydraulic buffer 14, the hydraulic buffer 14 absorbs the impact force to achieve buffering of the impact of the glass tube falling and prevent damage to the glass tube.

[0031] In an embodiment of the present utility model, preferably, the elastic plate 13 is made of polyurethane or polytetrafluoroethylene material. The rigid plate 16 is made of metal material.

[0032] In an embodiment of the present utility model, a spring 18 is further included. The upper end of the spring 18 is connected to the rotating plate 10, and the lower end is connected to the connecting plate 11. When the spring 18 is in a free state, the rotating plate 10 is in a horizontal state. When the glass tube falls, the rotating plate 10 rotates, and at this time the spring 18 stretches and stores energy. After the hydraulic buffer 14 absorbs the impact force, the spring 18 releases energy to pull the rotating plate 10 to the horizontal state, realizing the reset of the rotating plate 10.

[0033] In an embodiment of the present utility model, a nut I 19 is further included on the outer side of the upper end of the connecting plate 11 and a nut II 21 is included on the inner side of the upper end of the connecting plate 11. A bolt I 20 is screwed into the nut I 19, and a bolt II 22 is screwed into the nut II 21. When the rotating plate 10 is in a horizontal state, its lower end surface contacts the top of the bolt II 22. When the rotating plate 10 rotates to trigger the hydraulic buffer 14, its lower end surface contacts the top of the bolt I 20. By providing the bolt I 20 and the bolt II 22, a hard limit function is achieved to prevent the rotating plate 10 from rotating beyond the limit, further improving the reliability of use.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
