Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a glass tube precision cutting device. Background Technology

[0002] Pharmaceutical glass bottles are made from glass tubes. After the glass tubes are formed, they need to be cut to the required length. During the cutting process, a damp cloth needs to be placed above the cutting blade. As the cutting blade passes over the damp cloth, the cloth cools the blade and prevents the glass from cracking due to heat. In the past, the damp cloth was checked periodically to check its moisture level. Once it was dry, it was watered again. Sometimes, this was forgotten, which was not conducive to the glass cutting process. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a glass tube precision cutting device that automatically wets the cloth without affecting the glass cutting process.

[0004] To address the problems existing in the background technology, this utility model adopts the following technical solution: It includes a workbench with a cutting roller on it. A cutting blade is positioned above the cutting roller, connected to a connecting rod, which in turn is connected to a servo motor. The servo motor is fixed to a support frame. A wet cloth is suspended on the support frame, positioned above the cutting blade. A mineral water bottle is attached to the top of the support frame. The bottle cap at the bottom of the mineral water bottle passes through a drainage tube. One end of the drainage tube is inside the mineral water bottle, and the other end extends out of the bottle cap and connects to one end of a flexible hose. The flexible hose has a buffer tube and a flow regulator sequentially arranged from top to bottom. The other end of the hose extends downwards, with its bottom port positioned above the wet cloth.

[0005] The support frame is equipped with a fixing clip that passes through the hose and fixes the hose to the support frame. The beneficial effects of this utility model are its simple structure and ease of use. By using a mineral water bottle and a hose, it achieves the function of automatically watering the wet cloth, ensuring that the wet cloth cools the cutting blade at all times, thus preventing the cutting blade from overheating and cracking the glass. At the same time, the use of a buffer tube and a flow regulator achieves the purpose of regulating the water flow speed, ensuring that the wet cloth is moist but not dripping wet, preventing the glass from cracking again, reducing waste glass, and thus reducing production costs. Attached Figure Description

[0006] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0007] Reference Figure 1The present invention specifically adopts the following implementation method: It includes a workbench 1, on which a cutting roller 6 is provided. A cutting blade 7 is provided above the cutting roller 6. The cutting blade 7 is connected to a connecting rod 8, which is connected to a servo motor 13. The servo motor 13 is fixed on a support frame 11. A wet cloth 12 is suspended on the support frame 11, positioned above the cutting blade 7. A mineral water bottle 10 is tied to the top of the support frame 11. The cap of the mineral water bottle 10 passes through a drainage tube 9. One end of the drainage tube 9 is located inside the mineral water bottle 10, and the other end extends out of the cap of the mineral water bottle 10 and connects to one end of a flexible hose 2. The flexible hose 2 has a buffer tube 3 and a flow regulator 4 arranged sequentially from top to bottom. The other end of the flexible hose 2 extends downwards, with its bottom end positioned above the wet cloth 12. A fixing clip 5 is provided on the support frame 11, through which the flexible hose 2 passes, fixing the flexible hose 2 to the support frame 11.

[0008] When this glass tube precision cutting device is working, the formed glass tube is conveyed to the cutting roller 6, the servo motor 13 is started, and the servo motor 13 drives the cutting blade 7 on the connecting rod 8 to rotate through the connecting rod 8. The cutting blade 7 performs one cut for every rotation. The rotation period is constant, and the length of the glass tube being cut is constant.

[0009] As the cutting blade 7 rotates and cuts continuously, it becomes hot due to friction and heat generated during operation. When cutting glass again, the glass is prone to cracking due to the heat. Therefore, a wet cloth 12 is placed above the cutting blade 7. The wet cloth 12 is soaked in cold water. When the cutting blade 7 rotates to the top, it will come into contact with the wet cloth 12. The wet cloth 12 cools down the cutting blade 7, ensuring that the cutting blade 7 will not crack during cutting.

[0010] Cold water from mineral water bottle 10 enters hose 2 through drainage pipe 9. The cold water flows down hose 2 and eventually drips onto wet cloth 12. The continuous dripping water keeps the wet cloth 12 moist. To ensure that the wet cloth 12 is not slick, a buffer pipe 3 and a flow regulator 4 are installed sequentially on hose 2. The dripping cold water is first stored in the buffer pipe 3 and does not drip directly, thus slowing down the flow rate. The flow rate is then adjusted by the flow regulator 4. A lower flow rate results in a slower flow, and a higher flow rate results in a faster flow, thus adjusting the flow rate of the cold water to meet the production speed.

[0011] The flow regulator 4 passes through the hose 2. A ramp is provided on one side of the hose 2, and a roller is provided on the ramp. The roller rolls along the ramp and has a process of moving away from the hose 2 and then connecting tightly. When the roller moves away from the hose 2, the flow velocity is the maximum. When the roller is connected tightly to the hose 2, the flow velocity is the minimum.

[0012] To ensure that the bottom end of the hose 2 is always above the wet cloth 12, the bottom end of the hose 2 is fixed to the fixing clip 5, and the fixing clip 5 is fixed to the support frame 11 to ensure that the bottom of the hose 2 remains stationary.

[0013] In summary, this glass tube precision cutting device has a simple structure and is easy to use. By using a mineral water bottle and a flexible hose, it automatically wets the cloth, ensuring that the cloth constantly cools the cutting blade and preventing the glass from overheating and cracking. At the same time, the use of a buffer tube and a flow regulator allows for the adjustment of the water flow rate, ensuring that the cloth is moist but not slick, preventing glass from cracking, reducing waste glass, and thus lowering production costs.
