[0017] As attached Figure 2-8 As shown, the present invention provides a glass product sintering apparatus that can achieve the following: Figure 1 The diagram shows the gradual processing of glass tubes into drawn and sealed glass tubes.

[0018] The specific structure of this invention includes a cabinet, a wire drawing and forming mechanism 100, a rotary pressing mechanism 200, and a lamp holder translation mechanism 400 arranged sequentially on the cabinet along the process flow. A sealing and forming mechanism 300 is provided on one side between the rotary pressing mechanism 200 and the lamp holder translation mechanism 400. The glass tube is located on the rotary pressing mechanism 200. The lamp holder translation mechanism 400 is used to heat one end of the glass tube so that the sealing and forming mechanism 300 can perform a shrinking and sealing operation on that end. At the same time, the wire drawing and forming mechanism 100 is used to perform the wire drawing and forming operation on the glass tube. After the sealing and wire drawing processing of one end of the glass tube is completed, the rotary pressing mechanism 200 drives the glass tube to turn around and perform sealing processing on the other end of the glass tube, finally producing the product shown in the image. Figure 1 The image shows a drawn and sealed glass tube.

[0019] Specifically, the rotary clamping mechanism 200 is as shown in the attached figure. Figure 3 As shown, the system includes a base 201, an active roller 202 positioned above the base 201, a driven roller 203 positioned on one side of the active roller 202 and parallel to its axis, and a pressing roller 205 positioned above the active and driven rollers. The pressing roller 205 is adjusted in vertical position by a vertically positioned slide cylinder 204. Preferably, an inverted Y-shaped mounting bracket is provided on the slide cylinder 204, and pressing rollers 205 are installed at both ends of the bottom of the Y-shaped mounting bracket. The glass tube is located between the active roller 202, the driven roller 203, and the two pressing rollers 205. The pressing rollers 205 move up and down to press and release the glass tube.

[0020] The active idler roller 202 is mounted on the active idler roller shaft, and the driven gear 206 is mounted on the active idler roller shaft. A stepper motor with the active gear is set on the base 201. The active gear and the driven gear mesh to drive the active idler roller 202.

[0021] A planetary reducer 208 is fixedly installed inside the cabinet. A rotating disk 207 is set on the output shaft of the planetary reducer 208. The base 201 is fixedly connected to the rotating disk 207. The output end of the planetary reducer 208 is connected to the output shaft of the servo motor 209. The servo motor 209 and the rotating disk 207 are used to realize the rotation of the base 201, thereby driving the glass tube located on the main and driven rollers to deflect 180°, so as to realize the processing operation of both ends of the glass tube.

[0022] As attached Figure 4 , 5 As shown, the lamp head translation mechanism 400 includes a lamp holder bottom plate 401 fixed on the cabinet, a linear guide rail A402 set on the lamp holder bottom plate 401, a linear module A set on the linear guide rail A402, a movable support plate 403 fixed on the linear module A, and a sintered lamp head set on the movable support plate 403. The linear module A is used to drive the sintered lamp head to move closer to or away from the end of the glass tube that needs to be heated.

[0023] The sintering lamp head includes a hollow outer shell 404 and a liquefied gas chamber 405 disposed inside the outer shell 404. A gap is left between the liquefied gas chamber 405 and the outer shell 404 as an oxygen chamber. An oxygen inlet flange 408 is fixedly disposed at the bottom of the outer shell 404. An oxygen inlet port 406 is provided on the side wall of the oxygen inlet flange 408. The oxygen chamber is connected to the oxygen inlet port 406. A liquefied gas inlet port 407 is provided at the center of the bottom of the liquefied gas chamber 405. Several liquefied gas outlets 409 are arranged in a straight line at the top of the liquefied gas chamber 405. The liquefied gas outlets 409 are vertically upward. The oxygen chamber is connected to the liquefied gas outlets 409 through oxygen outlets 410. Each liquefied gas outlet 409 is connected to a separate oxygen outlet 410 on both sides. In this embodiment, the oxygen outlets 410 are horizontally disposed.

[0024] The liquefied gas tank 405 and the outer shell 404 are cylindrical. In this embodiment, the top of the liquefied gas tank 405 and the two sides of the liquefied gas outlet 409 are tapered, making the two sides of the liquefied gas outlet 409 inclined planes. A nearly semi-circular cover plate 411 is provided between the top of the liquefied gas tank 405 and the top of the outer shell 404. The oxygen inlet flange 408 is fixedly connected to the movable support plate 403. An igniter should also be provided on the outside of the liquefied gas outlet 409 for ignition operation.

[0025] The liquefied petroleum gas (LPG) in the sintering lamp head is ignited through the top elongated LPG outlet 409, forming a strip-shaped flame. Oxygen, through the oxygen chamber formed by the interlayer and the elongated oxygen outlets 410 located on both sides of the LPG outlet 409, assists in the combustion of the LPG. The oxygen's participation in combustion at the base of the flame effectively prevents detonation, making it safer and enabling the formation of a stable strip-shaped sintering flame.

[0026] As attached Figure 6 , 7 As shown, the sealing forming mechanism includes a sealing fixing plate 301 fixed on the mounting cabinet, a linear guide rail B horizontally arranged on the sealing fixing plate 301, a linear module B mounted on the linear guide rail B, a mounting plate 303 fixed on the linear module B, and a sealing forming plate fixed at the end of the mounting plate 303. The linear module B drives the sealing forming plate to move closer to or away from the end of the glass tube.

[0027] The sealing forming plate has an outward convex shape on the side facing the glass tube, including a flat portion 304 and beveled portions 305 disposed on the left and right sides of the flat portion 304. The beveled portions 305 are used to complete the narrowing action, and the flat portion 304 is used to complete the sealing action. The sealing forming plate is made of heat-resistant stainless steel 310S.

[0028] As attached Figure 8 As shown, the wire drawing forming mechanism 100 includes a wire drawing bottom plate fixed to the cabinet, a linear guide rail C101 mounted on the bottom plate, a linear module C mounted on the linear guide rail C101, a wire drawing fixing plate 102 mounted on the linear module C, a rodless cylinder 103 mounted on the wire drawing fixing plate 102, a stepped ejector pin 104 mounted on the rodless cylinder 103, and a glass tube stop block 105 fixed to the wire drawing fixing plate 102 and located at the end of the ejector pin 104. A bearing 106 for contacting the glass tube is provided on the glass stop block 105, and the tip of the ejector pin 104 faces the glass tube. The axes of the ejector pin 104 and the bearing 106 are collinear with the axis of the glass tube on the rotary pressing mechanism 200 to ensure good processing accuracy. The linear module C drives the wire drawing fixing plate 102 to move as a whole. The rodless cylinder 103 adopts a magnetic coupling rodless cylinder, which drives the ejector pin 104 to move to perform the wire drawing action, and ejects the molten glass into fine wires.

[0029] The process flow of this invention is as follows: 1. Loading: Align the left end of the glass tube with the glass tube stop 105 on the drawing and forming mechanism, and place the glass tube onto the two active rollers 202 and driven rollers 203 of the rotary pressing mechanism 200. The slide cylinder 204 retracts, driving the pressing roller 205 to press the glass tube firmly. The motor drives the active roller shaft to rotate, thereby causing the active roller 202 to drive the glass tube to rotate indefinitely.

[0030] 2. Sealing: The lamp head translation mechanism moves the sintering lamp head 400 degrees to the right end of the glass tube opening (as shown in the attached diagram). Figure 2 Near the point shown, the flame heats the glass tube opening to a molten state, and the sealing forming plate in the sealing forming mechanism 300 extends out. The inclined part 305 of the sealing forming plate first contacts the glass tube opening, realizing the glass tube narrowing action. The sealing forming plate continues to extend forward, and the flat part 304 of the sealing forming plate realizes the sealing forming of the glass tube.

[0031] 3. Stringing: After sealing is completed, the sealing and forming mechanism 300 returns to its initial state; The lamp head translation mechanism 400 returns to its initial state; The magnetically coupled rodless cylinder on the wire drawing forming mechanism 100 drives the ejector pin 104 to move, pushing the molten sealing end face into a fine wire shape. After a few seconds of waiting for the glass to cool, the ejector pin 104 retracts, completing the wire drawing forming.

[0032] 4. Rotation: The wire drawing process ends, and the wire drawing and forming mechanism returns to its initial state; The servo motor 209 drives the rotating disk 207 to rotate, thereby causing the base 201, active roller 202, driven roller 203 and pressing roller 205 located on it to rotate. The wire drawing end face rotates to the left, the wire drawing mechanism 100 moves to the working position, and the glass tube stop 105 fits against the wire drawing end face, restricting the glass tube from moving to the left.

[0033] 5. Sealing: The lamp head translation mechanism 400 pushes the sintering lamp head to the sintering station again, and the sealing and forming mechanism 300 extends forward again to complete the sealing operation on the other end.

[0034] 6. Material feeding: After sealing is completed, the lamp head translation mechanism 400 and the sealing forming mechanism 300 return to their initial state.

[0035] The active roller 202 of the rotary pressing mechanism 200 stops rotating, the slide cylinder 204 extends, the pressing roller 205 disengages from the glass tube, and the formed glass tube is manually removed.

[0036] This invention provides a rotary pressing mechanism 200 to drive the glass tube to rotate and deflect 180°. A lamp head translation mechanism 400, located on one side of the rotary pressing mechanism 200, heats the end of the glass tube to facilitate sealing by a sealing and forming mechanism 300. A wire drawing mechanism 100, located on the other side of the rotary pressing mechanism 200, draws the glass tube into wires. These multiple workstations work together to process a conventional glass tube into one sealed and wire-drawn glass tube. The entire device requires only manual loading and unloading; the rest is automated. The process is simple, efficient, and saves labor costs.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
