Description

Technical Field

[0001] This utility model relates to the field of bottom sealing machine technology, and in particular to a bottom sealing machine for lampworking glass tubes. Background Technology

[0002] The raw material for lampworking products is glass tubes. Before the glass tubes are blown, one end is heated to soften the glass and then sealed to serve as the bottom. The task of sealing the bottom of lampworking glass tubes requires the use of a bottom sealing machine.

[0003] In existing lampwork glass tube sealing machines, the flame outlet used to heat the end of the glass tube is usually directly exposed during use. After the end of the glass tube is heated, softened, and sealed, the flame outlet usually still maintains a certain temperature. The exposed flame outlet is at risk of being accidentally touched by humans. Manually covering the flame outlet is not only troublesome but also not timely enough. The sealing machine cannot automatically cover the flame outlet when not in use. Summary of the Invention

[0004] This utility model relates to a lampworking glass tube bottom sealing machine. It features a flame gun mounted on a movable mounting plate. When the machine is not in use, the flame gun automatically descends and is concealed within a protective casing, eliminating the risk of burns from residual heat. The glass tube is clamped onto a manual clamp, which is then indirectly driven by a rotary motor to rotate at a constant speed. During this rotation, the flame from the flame gun heats the end of the glass tube. The uniform rotation ensures even heating of the glass tube end. Furthermore, since there are four manual clamps, this invention can seal the bottoms of four glass tubes simultaneously, increasing production capacity.

[0005] In a first aspect, this utility model provides a lampsmith glass tube sealing machine, specifically comprising: a frame; feed motors fixedly mounted on the left and right sides of the top of the frame; a feed screw rotatably mounted at the center of the top of the frame; guide rail structures fixedly mounted on the front and rear sides of the top of the frame; mounting slides slidably mounted on the guide rail structures; a manual clamp rotatably mounted on the top of the inner part of the mounting slide; a rotary motor fixedly mounted inside the mounting slide; pushers fixedly mounted on the front and rear ends of the bottom of the mounting slide; a force-bearing groove formed inside the pusher; a protective component fixedly mounted at the center of the guide rail structure; guide posts fixedly mounted on the front and rear sides of the bottom of the protective component; the guide posts are cylindrical structures; a mounting plate slidably mounted on the guide posts; a flame gun body fixedly mounted on the top of the mounting plate; a connecting hose fixedly connected to the bottom of the flame gun body; and conversion components fixedly mounted on the front and rear sides of the bottom of the mounting plate.

[0006] Furthermore, the outer end of the feed screw is connected to the feed motor via a spline; the mounting slide is connected to the feed screw via threads; and a sprocket is fixedly mounted on the outer end of the manual clamp.

[0007] Furthermore, a sprocket is also fixedly mounted on the output shaft of the rotating motor, and the sprocket is connected to the sprocket at the outer end of the manual clamp via a chain; the bottom end of the force groove has an inclined structure.

[0008] Furthermore, a spring is embedded in the top of the mounting plate; the other end of the spring is embedded in the bottom of the protective component; and the flamethrower body is located inside the protective component.

[0009] Furthermore, the left and right ends of the conversion component are inclined; the outer end of the conversion component is also inserted into the inside of the force-receiving groove, and the inclined surface of the end of the conversion component is in close contact with the inclined surface of the force-receiving groove.

[0010] Furthermore, when the mounting slide moves the pushing member and the force-receiving groove inward, the inclined surface of the force-receiving groove will push against the inclined surface of the conversion member.

[0011] Furthermore, the inclined surface of the conversion component, after being pushed upwards, will move the mounting plate and the flamethrower body upwards.

[0012] This utility model provides a lampworker's glass tube bottom sealing machine, which has the following beneficial effects:

[0013] 1. By setting the flame gun body on a movable mounting plate, the flame gun body automatically descends and is stored inside the protective component when the bottom sealing machine is not in use, eliminating the risk of burns from the residual heat of the flame gun body. When the bottom sealing machine is ready to be used, the flame gun body will automatically rise to a suitable position with the end of the glass tube, so that the flame gun body can heat the end of the glass tube for bottom sealing.

[0014] 2. By clamping the glass tube onto a manual clamp, and then indirectly driving the manual clamp and the glass tube to rotate at a constant speed by a rotary motor, the end of the glass tube is heated by the flame emitted from the flame gun during the uniform rotation process. Due to the uniform rotation, the end of the glass tube can be heated evenly, which greatly improves the sealing effect of this bottom sealing machine on the glass tube and makes it less likely to have problems such as uneven ends or crooked bottoms.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please refer to Figures 1 to 5 Example 1:

[0027] This utility model proposes a lampworking glass tube sealing machine, comprising: a frame 1, with feed motors 2 fixedly installed on the left and right sides of the top of the frame 1; a feed screw 3 rotatably installed at the center of the top of the frame 1; guide rail structures 4 fixedly installed on the front and rear sides of the top of the frame 1; mounting slides 5 slidably installed on the guide rail structures 4; a manual clamp 6 rotatably installed at the top of the inside of the mounting slide 5; a rotary motor 7 fixedly installed inside the mounting slide 5; pushers 8 fixedly installed at the front and rear ends of the bottom of the mounting slide 5; force grooves 9 opened inside the pushers 8; a protective component 10 fixedly installed at the center of the guide rail structure 4; and a protective component 10 at the bottom front of the protective component 10. Guide columns 11 are fixedly installed on both sides of the rear. The guide columns 11 are cylindrical structures. Mounting plates 12 are slidably installed on the guide columns 11. A flame gun body 14 is fixedly installed on the top of the mounting plate 12. A connecting hose 15 is fixedly connected to the bottom of the flame gun body 14. Converters 16 are fixedly installed on the front and rear sides of the bottom of the mounting plate 12. By inserting the four glass tubes into the four manual clamps 6 respectively, and then starting the feed motor 2, it drives the feed screw 3 to rotate. The feed screw 3 rotates and drives the two mounting slides 5 to move inward relative to each other along the guide rail structure 4, so that the ends of the four glass tubes move toward the area of ​​the flame gun body 14.

[0028] In Example 2, based on Example 1, the outer end of the feed screw 3 is splined to the feed motor 2; the mounting slide 5 is connected to the feed screw 3 via threads; a sprocket is fixedly mounted on the outer end of the manual clamp 6; a sprocket is also fixedly mounted on the output shaft of the rotating motor 7, and this sprocket is connected to the sprocket at the outer end of the manual clamp 6 via a chain; the bottom end of the force groove 9 has an inclined structure; one end of the spring 13 is embedded in the top of the mounting plate 12; the other end of the spring 13 is embedded in the bottom of the protective member 10; the flame gun body 14 is located inside the protective member 10. During the movement of the mounting slide 5, the inclined surface of the force groove 9 will push against the inclined surface of the conversion member 16, causing it to be forced to move the mounting plate 12 and the flame gun body 14 upwards, so that the flame gun body 14 can rise from inside the protective member 10 and successfully rise to the processing area.

[0029] In Example 3, based on Example 2, the left and right ends of the conversion component 16 are inclined; the outer end of the conversion component 16 is also inserted into the inside of the force groove 9, and the inclined surface of the end of the conversion component 16 is in contact with the inclined surface of the force groove 9; when the mounting slide 5 drives the pusher 8 and the force groove 9 to move inward, the inclined surface of the force groove 9 will push against the inclined surface of the conversion component 16; after being pushed, the inclined surface of the conversion component 16 will move upward with the mounting plate 12 and the flame gun body 14. By starting the flame gun body 14 and the rotating motor 7, the rotating motor 7 indirectly drives the manual clamp 6 and the glass tube to rotate at a uniform speed, while the end of the glass tube is uniformly heated by the flame gun body 14, thus completing the sealing work of the end of the glass tube.

[0030] Working principle: In use, four glass tubes are inserted into the four manual clamps 6 respectively. Then, the feed motor 2 is started, which rotates the feed screw 3. The feed screw 3 rotates and moves the two mounting slides 5 inward along the guide rail structure 4, so that the ends of the four glass tubes move toward the area of ​​the flame gun body 14. During the movement, the inclined surface of the force groove 9 pushes against the inclined surface of the conversion part 16, so that the mounting plate 12 and the flame gun body 14 move upward. The flame gun body 14 rises and separates from the inside of the protective part 10, and at the same time rises to the processing area. Then, the flame gun body 14 and the rotating motor 7 are started, so that the rotating motor 7 indirectly drives the manual clamps 6 and the glass tubes to rotate at a constant speed. At the same time, the ends of the glass tubes are evenly heated by the flame gun body 14, thus completing the sealing work of the ends of the glass tubes.
