Description

They can be widely used in chemical industry, aerospace, military, family, hospital and other fields.
[0003] In the existing glass tube cutting, in order to keep the cut of the glass tube neat, the staff fully combines the physical properties of the glass and the effect of thermal stress. A scratch is made on the surface of the glass tube with a glass cutter, and then the inner wall area of the glass tube near the scratch is heated to generate thermal stress in the scratch area of the glass. When heated to a certain temperature, the stress accumulation in the scratch area reaches a critical point, and the glass tube breaks naturally, thereby achieving the precise division of the long glass tube into several small sections.
[0004] However, when using this method for cutting, the worker needs to stick the glass cutter to the surface of the glass tube, which will easily cause the scratch position to shift, thus affecting the cutting accuracy. In addition, when the glass tube breaks naturally, there may still be some areas between the glass tubes that are not completely broken, which require manual gentle pushing, making the entire cutting process more cumbersome and increasing the difficulty and uncertainty of manual operation.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model provides Figure 1-Figure 4 A glass tube cutting device is shown, including a cutting table 1, the cutting table 1 is used to place devices required for glass tube cutting, a heating device 4 is fixedly installed on one side of the cutting table 1, and the heating device 4 is composed of common equipment in the prior art, including a nozzle (the nozzle is annular in structure, and can heat the inner wall of the glass tube more evenly), a flame spray gun, an electric telescopic rod and other components, and the flame is sprayed from the nozzle by the flame spray gun, so as to heat the inner wall area of the glass tube near the scratch.
[0025] A rotating device 2 is fixedly installed on one side of the cutting table 1 away from the heating device 4. The rotating device 2 is composed of common equipment in the prior art, including components such as a motor, a transmission shaft and a hosting wheel. The hosting wheel is driven by the motor to rotate, thereby realizing the rotation of the glass tube on the rotating device 2. In cooperation with the glass cutter, a ring-shaped scratch can be quickly formed on the glass tube.
[0026] A lifting device 3 is provided between the heating device 4 and the rotating device 2. The lifting device 3 is composed of common equipment in the prior art, including components such as an electric slide rail, a slider, and a baffle, which will not be described in detail here.
[0027] The lifting device 3 is fixedly installed on the cutting table 1 .
[0028] Considering that during cutting, the worker needs to stick the glass cutter to the surface of the glass tube, cutting and scratching the surface of the glass tube, which may easily cause the position of the cut scratch to shift, thereby affecting the cutting accuracy. Therefore, a clamping mechanism is arranged above the cutting table 1, and the clamping mechanism includes a connecting block 7, and the connecting block 7 is slidably connected to the lifting device 3. A push rod 9 is movably penetrated on the connecting block 7, and the push rod 9 is used to connect the glass cutter for cutting the glass tube (the glass cutter includes a knife seat 8 and a cutting head 11).
[0029] Rotating rods 13 are fixedly mounted on both sides of the push rod 9 . The rotating rods 13 are used to connect the connecting block 7 and the push rod 9 . The rotating rods 13 are rotatably connected to the inner wall of the connecting block 7 .
[0030] Specifically, the knife holder 8 is fixedly installed at the bottom of the push rod 9, and the knife holder 8 is used to install the cutting head 11. The cutting head 11 is rotatably connected to the bottom of the knife holder 8. The electric cylinder 6 is fixedly installed on the top of the connecting block 7. The top of the push rod 9 is hinged on the telescopic end of the electric cylinder 6. The electric cylinder 6 is used to control the push rod 9 to rotate slightly with the rotating rod 13 as the center, so that the cutting head 11 fits with the surface of the glass tube.
[0031] During operation, the electric cylinder 6, the rotating device 2 and the heating device 4 are started, and the push rod 9 is pushed by the electric cylinder 6 to make the cutting head 11 fit the surface of the glass tube, and the rotating device 2 drives the glass tube to rotate, so that the cutting head 11 cuts a scratch on the surface of the glass tube, and then the nozzle is extended into the interior of the glass tube through the heating device 4 to heat the inner wall area of the glass tube near the scratch, thereby realizing the segmentation of the glass tube.
[0032] Furthermore, a connecting rod 12 is movably sleeved on the rotating rod 13, and a clamping block 10 is fixedly installed between the two connecting rods 12. The clamping block 10 is used to cooperate with the knife seat 8 so that the glass tube is clamped during the cutting process to avoid deviation during cutting. An arc-shaped groove is provided on one side of the clamping block 10 close to the knife seat 8, and the arc-shaped groove can fit well on the surface of the tubular object.
[0033] Specifically, a torsion spring 14 is fixedly connected to one side of the connecting rod 12. The torsion spring 14 is used to provide pre-tightening force to the clamping block 10 and help the clamping block 10 to reset. The torsion spring 14 is movably mounted on the rotating rod 13, and one end of the torsion spring 14 away from the connecting rod 12 is fixedly connected to the inner wall of the connecting block 7.
[0034] During operation, the glass tube is passed through the clamp block 10, and the clamp block 10 cooperates with the knife holder 8 to clamp the glass tube, thereby avoiding the position deviation of the scratches cut by the cutting knife head 11 and improving the cutting accuracy.
[0035] Taking into account that after the glass tube breaks naturally, there may still be some areas between the glass tubes that are not completely broken, which require manual pushing, making the entire cutting process more cumbersome and increasing the difficulty and uncertainty of manual operation. Therefore, a first ratchet 15 is fixedly installed on the side of the connecting rod 12 away from the torsion spring 14, and the first ratchet 15 is movably mounted on the rotating rod 13. The first ratchet 15 is meshed with a second ratchet 16, and the second ratchet 16 is slidably connected to the rotating rod 13. It should be noted that the second ratchet 16 can only slide laterally along the rotating rod 13.
[0036] Specifically, a spring 17 is fixedly connected to the second ratchet 16 , and the spring 17 is used to help the second ratchet 16 to reset. The spring 17 is movably sleeved on the rotating rod 13 , and one end of the spring 17 away from the second ratchet 16 is fixedly connected to the push rod 9 .
[0037] During specific operation, after the glass tube is cut, the electric cylinder 6 retracts, so that the knife seat 8 is separated from the surface of the glass tube. Since the planes on the first ratchet 15 and the second ratchet 16 are in contact with each other, the second ratchet 16 drives the first ratchet 15 to rotate together, thereby driving the clamping block 10 to rotate with the rotating rod 13 as the center, pushing the cut glass tube to separate from the main body, thereby realizing the extraction of the glass tube that is not completely broken, so that the entire cutting process is completed in an instant, reducing the difficulty of manual operation.
[0038] When this operation is completed, the electric cylinder 6 extends out and the knife seat 8 is attached to the surface of the glass tube. Since the inclined surfaces on the first ratchet 15 and the second ratchet 16 are in contact with each other, the second ratchet 16 compresses the spring 17 during rotation, so that the second ratchet 16 does not drive the first ratchet 15 to rotate together. Due to the pre-tightening force of the torsion spring 14 of the first ratchet 15, the clamp 10 returns to its original position, thereby preparing for the next cutting.
[0039] Considering the need to ensure that the length of the cut glass tubes is consistent during cutting, an inclined block 5 is provided below the knife seat 8. The inclined block 5 is used to facilitate the rapid collection of the cut glass tubes. The inclined block 5 is fixedly mounted on the cutting table 1. A stopper 18 is slidably connected to the inclined block 5. The stopper 18 is used to block the glass tube and limit the length of the glass tube.
[0040] During operation, the stopper 18 is slidably set at a position of a specified length to limit the cutting length of the glass tube. After cutting, the glass tube slides into a pre-prepared box through the inclined block 5, thereby achieving rapid collection and further reducing labor costs.
