[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] The present solution provides a colorant adding mechanism, comprising: an annular track 100 and a plurality of discharging units 200 movably connected to the annular track 100;

[0049] A glass tube may be inserted into the annular track 100;

[0050] The two sides of the annular track 100 are respectively a first side and a second side, and a plurality of discharge units 200 are disposed on both the first side and the second side;

[0051] The discharge unit 200 is provided with a nozzle 210 and a baffle 220. The baffle 220 can perform telescopic movement to block or open the nozzle of the nozzle 210. The baffle 220 can pull the solidified glass slag at the edge of the nozzle 210 when moving away from the nozzle of the nozzle 210, thereby opening the passage of the nozzle 210.

[0052] Adjacent discharging units 200 on the first side or the second side of the annular track 100 may be merged upward along the annular track;

[0053] The two opposite discharging units 200 on both sides of the annular track 100 may be combined along the axis direction.

[0054] The colorant adding mechanism provided in the present invention adds colorant on the rotating tube, so the colorant can be integrated into the glass liquid with a certain viscosity. By controlling the position, frequency and time of adding colorant, the size and shape of the color block can be adjusted, so the local color of the glass tube can be fully regulated.

[0055] In the colorant adding mechanism provided by the present scheme, the flow rate of the colorant sprayed in the annular direction can be increased by merging the two discharging units 200 in the annular direction, and the flow rate of the colorant sprayed in the axial direction can be increased by merging the two discharging units 200 in the axial direction. By regulating the flow rates in the annular direction and the axial direction, the size of the color block on the glass tube can be regulated.

[0056] The discharging unit 200 provided in the present solution is provided with a baffle plate 220, which can be extended and retracted to block or open the nozzle of the nozzle 210. Since the discharging unit 200 is intermittently fed, and the material provided is a high-temperature molten liquid, such as a glass liquid containing a colorant, or a pure colorant, the glassy material will solidify after cooling, and it is easy to block the outlet of the nozzle. In the long run, it is easy to block the nozzle. Therefore, the present solution sets a baffle plate 220 at the nozzle, and the baffle plate 220 can pull the solidified glass slag at the edge of the nozzle 210 in the process of moving away from the nozzle of the nozzle 210, thereby opening the channel of the nozzle 210.

[0057] Regarding the shape and structure of the baffle 220, specifically:

[0058] The baffle 220 includes a connecting portion 221 and an extending portion 222 . The extending portion 222 protrudes from the connecting portion 221 . The connecting portion 221 is connected to the motor shaft of the first motor 230 . The axial direction of the first motor 230 is perpendicular to the discharge direction of the nozzle 210 . The extending portion 222 is attached to the outer wall of the nozzle 210 .

[0059] For details, please see the attached Figure 4 , Figure 4 It is a cross-sectional view. It can be seen from the cross-sectional view that a part of the baffle 220 is connected to the motor shaft of the screw motor 320, and the other part extends upward and close to the nozzle 210. The extended part is the extension part 222. The extension part 222 extends forward with the movement of the screw motor 320. During the extension process, the residual material at the nozzle 210 mouth will be removed to prevent the residual material from contaminating the glass tube. When the nozzle 210 mouth needs to be opened, the extension part 222 will retract under the drive of the screw motor 320, thereby driving the solidified glass solidified at the nozzle 210 mouth to break, thereby preventing glass slag from clogging the nozzle 210 mouth.

[0060] The discharging unit 200 can move along the annular track 100, and the specific movement mechanism is as follows:

[0062] For details, please see Figure 2 and Figure 4 , Figure 4 In the embodiment, the second motor 240 is disposed inside the discharging unit 200. Figure 4From the perspective of the invention, the discharging unit 200 is arranged in a horizontal position, and its motor shaft faces the direction of the nozzle 210. As the motor shaft of the second motor 240 rotates, the gear is driven to rotate, and the gear is engaged with the meshing teeth of the annular track 100, thereby realizing annular motion. The discharging unit 200 realizes the addition action of any point of the glass tube through annular motion.

[0063] Furthermore, a hollow portion is provided at the bottom of the discharging unit 200 , and the hollow portions of the two discharging units 200 are connected to form a space for the annular track 100 to pass through.

[0065] The top of the discharging unit 200 is provided with an annular fixing portion 250, which includes a plurality of fixing points 251 provided on the top of the discharging unit 200. The fixing points 251 of two adjacent discharging units 200 are respectively connected by a locking member 252 between the discharging units 200 in the annular direction to lock the two discharging units 200. Furthermore, at least four fixing points 251 are provided, and the four fixing points 251 are arranged on the top of the discharging unit 200 in a roughly rectangular manner.

[0066] For details, please see Figure 2 , Figure 2 The two discharging units 200 are fixed by two annular fixing parts 250, so that the two discharging units 200 can move synchronously and discharge materials together, thereby increasing the discharge flow rate.

[0067] Two axially adjacent discharging units 200 can be combined, specifically:

[0068] The discharging unit 200 is also provided with a longitudinal fixing part 260, which is arranged at both ends of the discharging unit 200 along the radial direction of the annular track; the longitudinal fixing part 260 includes a latch part 261 arranged on one of the longitudinally arranged discharging units 200 and a socket 262 on the other discharging unit 200, and the two longitudinally arranged discharging units 200 are fixed by matching the latch and socket 262.

[0069] For details, please see Figure 4 , Figure 4It is a schematic diagram of the combined state of two axially adjacent discharging units 200, which are fixed by two longitudinal fixing parts 260 on both sides, wherein two latches 261 are provided at both ends of the upper discharging unit 200, and two insertion holes 262 are provided at both ends of the lower discharging unit 200. Of course, the above structure also has the following deformation forms, for example, two insertion holes 262 are provided at both ends of the upper discharging unit 200, and two latches 261 are provided at both ends of the two lower discharging units 200, or one end of the upper discharging unit 200 is provided with a latch 261 and the other end is provided with a insertion hole 262, and one end of the lower discharging unit 200 is provided with a insertion hole 262 and the other end is provided with a latch 261.

[0070] The colorant adding mechanism can also move laterally along the axis of the glass tube. Specifically:

[0071] The colorant adding mechanism further includes a transverse moving part 300 , and the transverse moving part 300 includes an annular moving member 310 disposed outside the annular track 100 , and the discharging unit 200 is connected to the annular moving member 310 .

[0072] The annular moving member 310 is connected to the lead screw motor 320 , and the axial direction of the lead screw is parallel to the axial direction of the glass tube.

[0073] Embodiment 2

[0074] This embodiment provides a glass tube production device, including the colorant adding mechanism described in the first embodiment, so as to have all the beneficial effects of the colorant adding mechanism.

[0075] In summary:

[0076] The colorant adding mechanism provided in the present invention adds colorant on the rotating tube, so the colorant can be integrated into the glass liquid with a certain viscosity. By controlling the position, frequency and time of adding colorant, the size and shape of the color block can be adjusted, so the local color of the glass tube can be fully regulated.

[0077] In the colorant adding mechanism provided by the present scheme, the flow rate of the colorant sprayed in the annular direction can be increased by merging the two discharging units 200 in the annular direction, and the flow rate of the colorant sprayed in the axial direction can be increased by merging the two discharging units 200 in the axial direction. By regulating the flow rates in the annular direction and the axial direction, the size of the color block on the glass tube can be regulated.

[0078] The discharging unit 200 provided in the present solution is provided with a baffle plate 220, which can be extended and retracted to block or open the nozzle of the nozzle 210. Since the discharging unit 200 is intermittently fed, and the material provided is a high-temperature molten liquid, such as a glass liquid containing a colorant, or a pure colorant, the glassy material will solidify after cooling, and it is easy to block the outlet of the nozzle. In the long run, it is easy to block the nozzle. Therefore, the present solution sets a baffle plate 220 at the nozzle, and the baffle plate 220 can pull the solidified glass slag at the edge of the nozzle 210 in the process of moving away from the nozzle of the nozzle 210, thereby opening the channel of the nozzle 210.
