Description

Technical Field

[0001] This utility model relates to the field of glass tube processing technology, and in particular to an automatic burner for lampworking glass tubes. Background Technology

[0002] The automatic glass tube firing machine is a specialized piece of equipment for processing and handling glass products, particularly widely used in the lighting manufacturing industry. Its main function is to automatically fire the ends of glass tubes to ensure a smooth, burr-free, and crack-free surface, thereby improving product quality and safety. Traditional firing processes rely heavily on manual operation, which is not only inefficient but also prone to quality variations due to inconsistent skill levels among operators, impacting overall production efficiency and cost control. To address these issues, the automatic firing machine was developed. Its working principle involves precisely controlling the heating time and temperature of the glass tube, softening the glass within a designated heating zone to form the desired firing end. Equipped with an automated feeding system and discharge device, it enables continuous production, significantly improving efficiency.

[0003] During the use of the burnishing machine, since the cut surface of the pipe is not smooth, it is necessary to heat and soften the edge of the pipe to make it smooth and not sharp. If it is all done manually by workers, it will not only waste time but also reduce efficiency. Utility Model Content

The gear 102 meshes with the tooth groove on the rack ring 206, and the gear 102 on the shaft of the motor 101 will slowly rotate when the motor 101 is started. The gear 102 rotates slowly, causing the rack ring 206 and heating plate 204 to rotate. Simultaneously, the tray 205 on the heating plate 204 rotates and adjusts its position. During the rotation of the heating plate 204, it pauses for ten seconds after rotating only one tray 205. A heating furnace 2 is fixedly installed in the groove in the middle of the workbench 1. A fixing frame 3 is fixedly installed in the rectangular groove at the right end of the workbench 1, and a through-hole is opened in the middle of the upper end of the fixing frame 3. Symmetrical side plates 301 are fixedly installed on the lower side wall of the fixing frame 3, and through bolts are inserted at both ends of the side plates 301. The lower end of the fixing frame 3 is fixedly inserted into the rectangular groove of the workbench 1. The bolts on the side plates 301 are rotated and inserted into the screws on the workbench 1. In the groove, the side plate 301 and the fixed frame 3 are fixed and restricted, and the fixed frame 3 will not move when touched, so the fixed frame 3 can stably support the electric cylinder 304. The two ends of the inner side wall of the fixed frame 3 are respectively provided with parallel guide grooves 302. Symmetrical positioning strips 303 are fixedly installed on the inner side wall of the fixed frame 3. When the bearing plate 305 moves downward and comes into contact with the positioning strips 303, it will stop moving. The electric cylinder 304 is fixedly installed through the round hole at the upper end of the fixed frame 3. The lower end of the electric cylinder 304 is fixedly connected to the bearing plate 305. When the electric cylinder 304 moves the position of the bearing plate 305 up and down, the bearing plate 305 and the electric push rod 307 will also move. At the same time, the left end of the electric push rod 307 is fixed. The positioning plate 308 will also move up and down to adjust its position. A bearing plate 305 is slidably installed on the inner wall of the fixed frame 3, and a through circular hole is opened in the middle of the bearing plate 305. Parallel guide blocks 306 are fixedly installed on both sides of the bearing plate 305. The guide blocks 306 are slidably installed in the guide groove 302. When the bearing plate 305 slides up and down, the guide blocks 306 are restricted by the guide groove 302, and the bearing plate 305 can only slide up and down to prevent the bearing plate 305 from tilting when sliding up and down. A through electric push rod 307 is fixedly installed at the circular hole in the middle of the bearing plate 305, and an arc-shaped positioning plate 308 is fixedly installed at the left end of the electric push rod 307. A positioning sensor 309 is installed at the upper end of the positioning plate 308.After the glass tube opening is heated and softened, the electric cylinder 304 pulls the support plate 305 upward. Then, the electric push rod 307 moves the positioning plate 308 and positioning sensor 309 to the left. When the positioning sensor 309 senses the glass tube below, the positioning plate 308 is moved downward to insert into the glass tube. The positioning plate 308 is then moved to contact the inner wall of the glass tube. Next, the electric rod 311 pushes the clamping plate 312 to the left, so that the concave surface of the clamping plate 312 is tightly pressed against the outer wall of the glass tube. At this point, the positioning plate 308 and clamping plate 312 are fixedly clamped to the inner and outer walls of the glass tube, respectively. The processed glass tube is then securely clamped and the electric... Cylinder 304 moves upward, lifting the processed glass tube from tray 205. Then, electric push rod 307 moves the glass tube to the right. When the glass tube reaches above the access port of worktable 1, it is moved downward and released, passing through the access port into the lower access box. By simply changing the access box, the falling glass tubes can be frequently received. A cantilever plate 310 is fixedly installed on the left end of electric push rod 307, and a through-type electric rod 311 is fixedly installed on the lower end of the cantilever plate 310. An arc-shaped clamping plate 312 is fixedly installed on the left end of electric rod 311, allowing the clamping plate 312 to be moved left and right using electric rod 311.

[0026] The heating furnace 2 has a support platform 201 at its upper edge. When the heating furnace 2 is started, high temperatures are emitted from inside. These high temperatures are transmitted through the support platform 201 to heat the heating plate 204 above it. The heating plate 204 also heats the tray 205 above it, creating a high temperature. The glass tube is then placed in the tray 205 and heated to soften and smooth it. A connecting screw groove 202 is provided in the middle of the upper part of the heating furnace 2. A rotating ring 203 is rotatably mounted on the support platform 201, and a heating plate is fixedly mounted on the outer annular side wall of the rotating ring 203. 204, and a ring tray 205 is fixedly installed on the upper end of the heating plate 204. A rack ring 206 is fixedly installed on the outer annular side wall of the heating plate 204. A limiting cover 207 is installed on the top of the heating furnace 2. A handle is fixedly installed on the upper end of the limiting cover 207. Grasping the handle on the limiting cover 207 makes it easy to move or rotate. A connecting stud 208 is fixedly installed in the middle of the bottom of the limiting cover 207. The connecting stud 208 is rotated and inserted into the connecting screw groove 202. At this time, the bottom of the limiting cover 207 is attached to the top of the rotating ring 203.

[0027] Example 2, based on Example 1, such as Figure 1 and Figure 4As shown, symmetrical side plates 301 are fixedly installed on the side wall at the lower end of the fixed frame 3. Through bolts are inserted at both ends of the side plates 301. After removing the side plates 301 and bolts, the fixed frame 3 is fixedly welded to the workbench 1 to stabilize and restrict the fixed frame 3. This way, the fixed frame 3 will not tilt when touched, avoiding the bolts from loosening after long-term use and failing to stabilize the fixed frame 3. It also saves on parts costs.

[0028] The working principle of this embodiment is as follows: When in use, the heating furnace 2 emits high temperature, which heats the heating plate 204 above the support platform 201. The heating plate 204 also heats the tray 205 above, creating a high temperature. This heat softens the vertical lamp glass tube opening, causing it to adhere to the tray 205, temporarily restricting the glass tube. The gear 102 on the shaft of the starting motor 101 slowly rotates, driving the rack ring 206 and the heating plate 204 to rotate. Simultaneously, the tray 205 on the heating plate 204 rotates and adjusts its position. The glass tube opening, placed in the tray 205, softens and becomes smooth. The electric cylinder 304 pulls the support plate 305 upward, and then the electric push rod 307 moves it to the left. Positioning plate 308 and positioning sensor 309: When positioning sensor 309 senses the glass tube below, positioning plate 308 is moved downward to insert into the glass tube, and then positioning plate 308 is moved to fit against the inner wall of the glass tube. Then, electric rod 311 pushes clamping plate 312 to the left, and the concave surface of clamping plate 312 is pressed tightly against the outer wall of the glass tube. At this time, positioning plate 308 and clamping plate 312 will be fixedly clamped on the inner and outer walls of the glass tube respectively. The processed glass tube is firmly clamped and electric cylinder 304 is used to move it upward to lift the processed glass tube from the tray 205. Then, electric push rod 307 is used to move the glass tube to the right. When the glass tube moves to the top of the receiving port of worktable 1, the glass tube is moved downward and released to fall into the receiving box below through the receiving port.
