Description

Technical Field

[0001] This utility model relates to the technical field of quartz product processing equipment, specifically a four-station dotting machine for glass products. Background Technology

[0002] In the current glass tube processing field, the process of marking glass tubes with dots (such as scales, markings, etc.) still has the following technical limitations: some production scenarios rely on manual operation, using handheld tools or fixed devices to mark the glass tubes. This method is not only slow and inconsistent, but also prone to marking position deviation due to operator fatigue or error, making it difficult to meet the needs of industrialized mass production.

[0003] In existing automated equipment, the heating flame (used to locally soften the glass tube to assist in marking) and the marking mechanism are usually fixed on the same horizontal straight line, lacking dynamic adjustment capability. Position adjustment relies on manual intervention: the horizontal position of the heating flame needs to be manually adjusted to adapt to glass tubes of different diameters or shapes, leading to production interruptions and reduced overall efficiency. The height is not adjustable: the marking mechanism cannot automatically rise and fall according to changes in the height or curvature of the glass tube, resulting in uneven marking depth or inability to accurately contact the tube surface, especially in the processing of irregularly shaped glass tubes (such as conical or curved tubes), where defects are significant.

[0004] Due to the poor linkage between the heating flame and the marking mechanism, the marking speed usually needs to be reduced to wait for manual calibration in order to avoid marking errors, which further restricts production capacity.

[0005] Therefore, we propose a four-station marking machine for glass products. Utility Model Content

[0006] The purpose of this invention is to provide a four-station dotting machine for glass products to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a four-station marking machine for glass products, comprising a walking cylinder, a mounting frame, a mounting base ring, a glass tube gripper, and a glass tube lifting cylinder; A cylinder mounting bracket is fixedly installed on the right end of the mounting bracket; The slide rail is fixedly installed on the top of the mounting bracket; A dotting device mounting plate is mounted on the slide rail.

[0014] Preferably, one end of the travel cylinder is connected to the steering plate via a pin.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The traveling cylinder pushes the steering plate to move, which in turn moves the dotting device mounting plate. The dotting device mounting plate moves on the slide rail, and the needle rod and needle head mounted on the dotting device mounting plate move accordingly. During the movement of the steering plate, the left half of the steering plate is tilted, and the steering plate pushes the steering wheel to rotate. The steering wheel drives the air intake copper pipe to rotate through the clamping mechanism. The burner at the end of the air intake copper pipe rotates and moves away from the needle head, so that the needle head performs dotting work on the glass tube. This device drives the burner to rotate by the movement of the steering plate. When dotting the glass tube, there is no need to manually move the position of the burner, thereby improving the efficiency of dotting the glass tube. Moreover, the four-station dotting process speeds up the dotting efficiency of the glass tube and improves the mass production of glass tubes.

[0016] 2. Rotate the threaded rod, and the threaded hole on the fixed block will engage with the threaded rod, causing the fixed block to move up or down. The fixed block will then move the connecting plate up or down via the lifting plate, which in turn will move the mounting frame up or down. The marking device on the mounting frame will then move up or down, thereby marking different height positions on the glass tube. Attached Figure Description

For marking work on the glass tube, the glass tube is fixed using the glass tube claw clamp 15, and the glass tube is pushed up to the marking position by the glass tube lifting cylinder. At this time, the air inlet copper pipe 12 is connected to the gas tank, and hydrogen or propane is introduced into the air inlet copper pipe 12. The gas is then ignited by the burner 13 and sprayed out to heat the glass tube. When the glass tube is heated to the temperature required for the marking work, the travel cylinder 1 is activated. The travel cylinder 1 pushes the steering plate 9 to move, and the steering plate 9 drives the marking device mounting plate 3 to move, thus rotating the marking device mounting plate. The mounting plate 3 moves on the slide rail 21, and the needle rod 6 and needle 7 mounted on the mounting plate 3 of the dotting device move accordingly. During the movement of the steering plate 9, the left half of the steering plate 9 is tilted, and the steering plate 9 pushes the steering wheel 10 to rotate. The steering wheel 10 drives the air intake copper pipe 12 to rotate through the clamping mechanism 24. The burner 13 at the end of the air intake copper pipe 12 rotates and moves away from the needle 7, so that the needle 7 performs dotting work on the glass tube. This device drives the burner 13 to rotate by moving the steering plate 9. When dotting the glass tube, it is not necessary to manually move the position of the burner, thereby improving the efficiency of dotting the glass tube.

[0020] Reference embodiment: A through groove 19 is provided in the middle of the vertical adjustment plate 5. A fixing block 23 is provided in the through groove 19. A threaded rod 26 is provided on the fixing block 23. A retaining ring 20 is provided on the threaded rod 26. The through groove 19 passes through the vertical adjustment plate 5. The fixing block 23 passes through the through groove 19 and is fixedly connected to the lifting plate 18. A threaded hole that mates with the threaded rod 26 is provided in the middle of the fixing block 23. The bottom end of the threaded rod 26 is connected to the bottom of the through groove 19 by a bearing. When the threaded rod 26 is rotated, the threaded hole on the fixing block 23 mates with the threaded rod 26, causing the fixing block 23 to move up or down. The fixing block 23 drives the connecting plate 22 to move up or down through the lifting plate 18. The lifting plate 18 and the vertical adjustment plate 5 are connected by a dovetail plate structure. The connecting plate 22 drives the mounting frame 4 to move up or down. The dotting device mounting plate 3 on the mounting frame 4 moves up or down, thereby performing dotting work at different height positions of the glass tube.

The upper clamping plate 241 and the lower clamping plate 241 fix the air intake copper pipe 12 by using a bolt passing through the fixing hole 244 and using a nut to cooperate with the bolt. The needle bar pressure block 8 adopts the same structure as the clamping mechanism 24 to fix the needle bar 6. The difference is that the lower part of the pressure block 8 is provided with a threaded hole, and the upper part is the same fixing hole. The bolt passes through the fixing hole and connects with the threaded hole to fix the needle bar 6.

[0022] Reference embodiment: The left half of the steering plate 9 is set as an inclined surface. During the movement of the steering plate 9, the air intake copper pipe 12 is set as an L-shape and passes through the burner frame 11. The air intake copper pipe 12 is movably connected to the inner wall of the burner frame 11. The steering plate 9 pushes the steering wheel 10 to rotate. The steering wheel 10 drives the air intake copper pipe 12 to rotate through the clamping mechanism 24. The air intake copper pipe 12 rotates in the burner frame 11, adjusting the position of the burner 13 so that the burner 13 rotates away from the needle bar 6, and will not affect the dotting work of the needle bar 6 and the needle 7.

[0023] Reference embodiment: One end of the travel cylinder 1 is connected to the steering plate 9 by a pin. The travel cylinder 1 pushes the steering plate 9 to move, which in turn moves the dotting device mounting plate 3 to dot the glass tube.
