Description

Technical Field

[0001] The utility model relates to the technical field of glass tube sealing, in particular to a glass tube end sealing device. Background Technique

[0002] During the production of glass tubes, flame cutting and sealing are required. The existing sealing devices have relatively complex processes, which affect the processing efficiency of glass tubes. Moreover, during hot melt sealing, the heating is uneven, affecting the sealing quality.

[0003] A medicinal glass tube end sealing device proposed in Patent CN111606555A can complete the sealing in only three steps through the designed preheating mechanism, heating mechanism and sealing mechanism. The process is simple and easy to control, which speeds up the processing efficiency of medicinal glass tubes. Moreover, the energy consumption required for heating is reduced, saving gas and achieving the purpose of energy conservation and emission reduction. Through the evenly distributed flame spraying ports on the arc-shaped mounting plate and the cooperation between the tooth grooves of the transportation mechanism and the moving seat, the periphery of the glass tube is preheated evenly, and through the uniform heating of the heating mechanism, the glass tube quickly reaches a high-quality hot melt state, thus improving the sealing quality.

[0004] In the above solution, the glass tube is heated and melted by a cyclic rotation method and then sealed in cooperation with the subsequent process. However, during the production of glass tubes, it is usually necessary to cool down the glass tube after hot melt sealing. During this process, the glass tube needs to be transferred to a cooling device for cooling treatment, and manual operation during the transfer is likely to cause burns. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a glass tube end sealing device to solve the problems raised in the above background technology. The structure of the utility model is novel. Through the clamping assembly, glass tubes with different diameters can be clamped, and the front end is pushed into the heating assembly for hot melting. Through the rotation of the rotating cylinder, the port of the glass tube is heated more evenly. After the sealing is completed, the glass tube is directly pushed out by the insertion rod at the end of the rotating cylinder and sent into the blowing ring for heat dissipation, thus saving the intermediate transfer process and avoiding being scalded by humans or damaging the glass tube.

[0006] To achieve the above object, the utility model is realized through the following technical solutions: A glass tube end sealing device includes a bottom plate. A clamping assembly is provided on the top of the bottom plate. The clamping assembly includes a rotating cylinder. Two clamping frames are symmetrically provided at the front end of the rotating cylinder. A first electric push rod is fixed to the outer end of the rotating cylinder corresponding to the clamping frame. The extending end of the first electric push rod is fixed to the outside of the clamping frame. A moving groove is formed on the surface of the bottom plate, and a mounting seat is slidably installed inside the moving groove. The rotating cylinder is rotatably installed on the mounting seat through a bearing. A heating assembly is provided on the surface of the bottom plate on the other side of the clamping frame. The heating assembly includes an igniter. There are two groups of igniters arranged up and down. A blowing ring is installed at the rear end of the bottom plate where the heating assembly is located.

[0007] Further, a driving lead screw is rotatably installed in the moving groove through a bearing, and the mounting seat is meshed and sleeved on the driving lead screw.

[0008] Further, a toothed ring is fixed on the surface of the rotating cylinder. A motor is fixed on one side of the mounting seat where the rotating cylinder is located, and a gear is fixed to the output end of the motor. The gear is meshed and connected to the toothed ring.

[0009] Further, a plug rod is slidably inserted into the tail end of the rotating cylinder, and a push plate is fixed to the end of the plug rod that penetrates into the rotating cylinder. A spring is sleeved on the outer surface of the plug rod at the outer end of the rotating cylinder, and the other end of the spring is fixed to the rotating cylinder.

[0010] Further, an annular elastic layer is provided on the inner wall of the rotating cylinder, and the size of the push plate of the plug rod is smaller than the inner diameter of the elastic layer.

[0011] Further, the heating assembly further includes a vertical frame. Vertical frames are fixed on both sides of the bottom plate where the igniters are located, and two groups of mounting plates are slidably installed inside the vertical frames. The two igniters are respectively fixed on the surfaces of the mounting plates.

[0012] Further, a bidirectional electric push rod is fixed between the two groups of mounting plates on the inner wall of the vertical frame, and the extending end of the bidirectional electric push rod is fixedly connected to the mounting plate.

[0015] The utility model drives two sets of mounting plates to slide along the vertical frame through a bidirectional electric push rod, adjusts the distance between the upper and lower two sets of igniters, so as to be applicable to glass tubes with different calibers, and at the same time keeps the surface of the igniter close to the port of the glass tube for hot melting.

[0016] The utility model adjusts the distance between two sets of clamping frames through the first electric push rod on the periphery of the rotating cylinder.

[0017] The utility model drives the gear to rotate and mesh with the gear ring through the motor, and then the rotating cylinder rotates, so that the surface of the port of the glass tube is heated more evenly.

Detailed Description of the Preferred Embodiments

[0024] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.

[0025] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a glass tube end sealing device, including a bottom plate 1. A clamping assembly 2 is provided on the top of the bottom plate 1. The clamping assembly 2 includes a rotating cylinder 24. Two clamping frames 25 are symmetrically provided at the front end of the rotating cylinder 24. A first electric push rod 26 is fixed to the outer end of the rotating cylinder 24 corresponding to the clamping frame 25. The extending end of the first electric push rod 26 is fixed to the outside of the clamping frame 25. A moving groove 11 is formed on the surface of the bottom plate 1, and a mounting seat 12 is slidably installed inside the moving groove 11. The rotating cylinder 24 is rotatably installed on the mounting seat 12 through a bearing. A heating assembly 3 is provided on the surface of the bottom plate 1 on the other side of the clamping frame 25. The heating assembly 3 includes an igniter 34. There are two groups of igniters 34 arranged up and down. A blowing ring 4 is installed at the rear end of the bottom plate 1 where the heating assembly 3 is located. When using the device, insert the tail end of the glass tube into the rotating cylinder 24, and then clamp and fix the glass tube by the two clamping frames 25. The port of the glass tube is exposed, and then push it along the moving groove 11 to send the port of the glass tube into the heating assembly 3 for hot melting. After the hot melting is completed, seal the glass tube by manual extrusion (this part is a common manual operation for sealing, which can seal or cut off the glass tube), and then send the port of the glass tube into the blowing ring 4 for heat dissipation.

[0026] In this embodiment, a driving lead screw 13 is rotatably installed in the moving groove 11 through a bearing. The mounting seat 12 is meshed and sleeved on the driving lead screw 13. The driving lead screw 13 is composed of an existing driving motor and a screw rod, which can drive the mounting seat 12 to move along the inside of the moving groove 11, so as to facilitate moving the clamping assembly 2 away from the heating assembly 3 and facilitate the insertion and clamping and fixing of the glass tube.

[0027] In this embodiment, a gear ring 23 is fixed on the surface of the rotary drum 24. A motor 21 is fixed on one side of the mounting seat 12 and located at the rotary drum 24, and a gear 22 is fixed at the output end of the motor 21. The gear 22 is meshed with the gear ring 23. A plug rod 28 is slidably inserted into the tail end of the rotary drum 24, and a push plate is fixed at one end of the plug rod 28 that penetrates into the rotary drum 24. A spring 29 is sleeved on the outer end surface of the rotary drum 24 of the plug rod 28, and the other end of the spring 29 is fixed to the rotary drum 24. An annular elastic layer 27 is arranged on the inner wall of the rotary drum 24, and the size of the push plate of the plug rod 28 is smaller than the inner diameter of the elastic layer 27. By adjusting the distance between the two clamping frames 25 through the first electric push rod 26 on the periphery of the rotary drum 24, and in cooperation with the arrangement of the elastic layer 27 on the inner wall of the rotary drum 24, glass tubes with different diameters and lengths can be accommodated and clamped. At the same time, the tail end of the glass tube will be in pressing contact with the push plate of the plug rod 28 after being inserted, so as to push the plug rod 28 out of the tail end of the rotary drum 24, which is convenient to push out the glass tube through the plug rod 28. The motor 21 drives the gear 22 to rotate and mesh with the gear ring 23, and then the rotary drum 24 rotates, making the surface of the glass tube port heat more evenly. After heating is completed, after part of the residual heat on the surface of the glass tube dissipates, manually push the plug rod 28 to push the glass tube out from the rear end, so that the port of the glass tube passes through the heating assembly 3 and enters the inside of the blowing ring 4.

[0028] In this embodiment, the heating assembly 3 further includes vertical frames 31. The bottom plate 1 is fixed with vertical frames 31 on both sides of the igniter 34, and two mounting plates 33 are slidably installed inside the vertical frames 31. The two igniters 34 are respectively fixed on the surfaces of the mounting plates 33. A bidirectional electric push rod 32 is fixed between the two mounting plates 33 on the inner wall of the vertical frame 31, and the extending end of the bidirectional electric push rod 32 is fixedly connected to the mounting plate 33. The two mounting plates 33 are driven by the bidirectional electric push rod 32 to slide along the vertical frame 31 to adjust the distance between the upper and lower igniters 34, so as to be applicable to glass tubes with different diameters, and at the same time keep the surface of the igniter 34 close to the glass tube port for hot melting.

[0029] In this embodiment, air holes 41 are equidistantly arranged on the inner wall surface of the blowing ring 4, and a small fan 42 is fixed at the bottom of the blowing ring 4. The air outlet of the small fan 42 is communicated with the inner cavity of the blowing ring 4. The small fan 42 blows cold air out from the air holes 41 through the inner cavity of the blowing ring 4 to cool the end of the glass tube sealed in the blowing ring 4.

[0030] When using the device, insert the tail end of the glass tube into the inside of the rotating cylinder 24, and then clamp and fix the glass tube through two sets of clamping frames 25. The port of the glass tube is exposed, and then it is pushed along the moving groove 11 to send the port of the glass tube into the heating assembly 3 for hot melting. The two-way electric push rod 32 drives the two mounting plates 33 to slide along the vertical frame 31 to adjust the distance between the upper and lower igniters 34, so as to be applicable to glass tubes of different calibers. At the same time, keep the surface of the igniter 34 close to the port of the glass tube for hot melting. The motor 21 drives the gear 22 to rotate and engage with the gear ring 23, and then the rotating cylinder 24 rotates, making the surface of the port of the glass tube heat more evenly. After the hot melting is completed, the glass tube is sealed by manual extrusion. Manually push the insertion rod 28 to push the glass tube out from the rear end, so that the port of the glass tube passes through the heating assembly 3 and enters the inside of the blowing ring 4. The small fan 42 blows cold air out from the air holes 41 through the inner cavity of the blowing ring 4 to cool the end of the glass tube sealed inside the blowing ring 4.
