The glass tubes on the glass tube conveyor belt move to the right side of the glass tube conveyor belt under the action of the glass tube right lateral shifting device.

By extending and shortening the electric push rod, the angle between the glass tube baffle 205 and the buffer device support bracket 203 is adjusted.
[0032] The glass tube receiving drum mounting flange 207 is installed on both sides of the glass tube receiving drum 206 through bolts. The glass tube receiving drum mounting flange 207 is a hollow tube. The buffer device support solid shaft 210 and the buffer device support hollow shaft 212 pass through the glass tube receiving drum mounting flange 207 respectively and are axially aligned, and are installed on the buffer device bracket 203 by using the buffer device support bearing 209; the buffer device support hollow shaft 212 can be externally connected to a gas source. The receiving drum drive sprocket 208 is fixed on the glass tube receiving drum mounting flange 207 and is connected to an external power source, so as to drive the glass tube receiving drum 206 to rotate and keep the buffer blowing air pipe 211 stationary.

There is an included angle between the center line of the buffer blowing air guiding pipe 2112 and the center line of the buffer blowing air pipe main body 2111, and the range of the included angle is 25° - 50°, so as to provide buffering for the falling glass tube. The buffer blowing air pipe counterweight 2113 is fixed below the buffer blowing air pipe main body 2111 to ensure that the center of mass of the buffer blowing air pipe 211 is below the center line of the buffer blowing air pipe main body 2111 to ensure the operation stability of the buffer blowing air pipe 211.
[0034] The glass tube receiving drum 206 includes a glass tube receiving plate 2061, a receiving drum air outlet hole 2062, a glass tube receiving drum main body 2063, a glass tube receiving drum outer mounting flange 2064 and a glass tube receiving drum inner mounting flange 2065. One end of the glass tube receiving plate 2061 is fixed on the glass tube receiving drum main body 2063, and the other end of the glass tube receiving plate 2061 is bent to reduce the sliding speed of the glass tube.
[0035] A buffer blowing area is provided between the glass tube receiving plates on the glass tube receiving drum main body 2063. The buffer blowing area is arranged with receiving drum air outlet holes 2062, and the arrangement position of the receiving drum air outlet holes 2062 corresponds to that of the buffer blowing air guiding pipe 2112. There is an included angle between the receiving drum air outlet hole 2062 and the center line of the glass tube receiving drum main body 2063, and the range of the included angle is 25° - 50°. And the included angle between the receiving drum air outlet hole 2062 and the center line of the glass tube receiving drum main body 2063 should be equal to the included angle between the center line of the buffer blowing air guiding pipe 2112 and the center line of the buffer blowing air pipe main body 2111, so as to reduce the loss of gas between the buffer blowing air guiding pipe 2112 and the receiving drum air outlet holes 2062.
[0036] The installation flanges 2064 of the glass tube receiving drum are installed on both sides of the glass tube receiving drum body 2063, and the glass tube receiving drum 206 is fixed to the glass tube receiving drum installation flange 207 through bolts. If it is necessary to maintain the compactness of the glass tube receiving drum 206, the glass tube receiving drum installation flange 207 can be installed on the inner installation flange 2065 of the glass tube receiving drum; by adjusting the relative position of the buffer device support bearing 209 on the buffer device bracket 203, the distance between the glass tube receiving drum 206 and the glass tube baffle 205 can be changed to ensure that the glass tubes meeting the production quality requirements fall onto the glass tube slide 202, and the glass tubes not meeting the production quality requirements are blocked by the glass tube baffle 205 and fall into the waste pit.
[0037] The glass tube leftward transverse movement device has three levels, including two first-level glass tube leftward transverse movement devices 305, two second-level glass tube leftward transverse movement devices 306, and two third-level glass tube leftward transverse movement devices 307 respectively.

[0038] Each glass tube transverse movement device is suspended above the glass tube conveyor belt through a transverse movement suspension device 303. The transverse movement suspension device 303 includes a transverse movement suspension bracket 3031 and a transverse movement suspension frame 3032. The transverse movement suspension bracket 3031 is provided with a T-shaped cross-section groove, so that the transverse movement suspension frame 3032 can be installed on the transverse movement suspension bracket 3031 and can move left and right. The transverse movement suspension frame 3032 is fixed to each glass tube transverse movement device through bolts respectively.
[0039] The structures of the first-level glass tube leftward transverse movement device 305, the second-level glass tube leftward transverse movement device 306, the third-level glass tube leftward transverse movement device 307, the first-level glass tube rightward transverse movement device 309, the second-level glass tube rightward transverse movement device 310, and the third-level glass tube rightward transverse movement device 311 are the same. Taking the third-level glass tube leftward transverse movement device 307 as an example for illustration, the third-level glass tube leftward transverse movement device 307 includes a transverse movement device support bearing seat 312, a transverse movement conveyor belt 313, a transverse movement conveyor belt driving drum 314, a transverse movement conveyor belt driving drum support shaft 315, a long transverse movement elastic column 316, and a short transverse movement elastic column 317. The short transverse movement elastic column 317 is installed between two long transverse movement elastic columns 316 to form a concave curve, thereby increasing the contact area between the short transverse movement elastic column 317, the long transverse movement elastic column 316, and the glass tube.
[0040] The first-stage leftward transverse movement device 305 for the glass tube, the second-stage leftward transverse movement device 306 for the glass tube, the third-stage leftward transverse movement device 307 for the glass tube, the first-stage rightward transverse movement device 309 for the glass tube, the second-stage rightward transverse movement device 310 for the glass tube, and the third-stage rightward transverse movement device 311 for the glass tube are all installed on the transverse movement suspension bracket 3032 through the transverse movement device support bearing seat 309. The transverse movement suspension bracket 3031 is installed above the transverse movement device bracket 301. The relative position between the transverse movement suspension bracket 3031 and the transverse movement device bracket 301 can be adjusted to adjust the relative position between the transverse movement device 3 and the glass tube conveyor belt 302.
[0041] The first-stage leftward transverse movement device 305 for the glass tube, the second-stage leftward transverse movement device 306 for the glass tube, the third-stage leftward transverse movement device 307 for the glass tube, the first-stage rightward transverse movement device 309 for the glass tube, the second-stage rightward transverse movement device 310 for the glass tube, and the third-stage rightward transverse movement device 311 for the glass tube only have length differences. The length of the first-stage leftward transverse movement device 305 for the glass tube is less than the length of the second-stage leftward transverse movement device 306 for the glass tube, and the length of the second-stage leftward transverse movement device 306 for the glass tube is less than the length of the third-stage leftward transverse movement device 307 for the glass tube; the length of the first-stage rightward transverse movement device 309 for the glass tube is less than the length of the second-stage rightward transverse movement device 310 for the glass tube, and the length of the second-stage rightward transverse movement device 310 for the glass tube is less than the length of the third-stage rightward transverse movement device 311 for the glass tube.
[0042] To ensure the compactness of the glass tube transverse movement device 3, the spacing between the first-stage leftward transverse movement device 305 for the glass tube, the second-stage leftward transverse movement device 306 for the glass tube, the third-stage leftward transverse movement device 307 for the glass tube, the first-stage rightward transverse movement device 309 for the glass tube, the second-stage rightward transverse movement device 310 for the glass tube, and the third-stage rightward transverse movement device 311 should be ensured to be between 100 mm and 300 mm. According to the glass tube defect judgment result, the tractor 1 cuts out glass tubes of various lengths; when the length of the glass tube meets the maximum length required for production, the first-stage leftward transverse movement device 305 for the glass tube, the second-stage leftward transverse movement device 306 for the glass tube, the third-stage leftward transverse movement device 307 for the glass tube, the first-stage rightward transverse movement device 309 for the glass tube, the second-stage rightward transverse movement device 310 for the glass tube, and the third-stage rightward transverse movement device 311 do not start; when the length of the glass tube is less than the maximum length required for production, the first-stage leftward transverse movement device 305 for the glass tube, the second-stage leftward transverse movement device 306 for the glass tube, the third-stage leftward transverse movement device 307 for the glass tube, the first-stage rightward transverse movement device 309 for the glass tube, the second-stage rightward transverse movement device 310 for the glass tube, and the third-stage rightward transverse movement device 311 start to work.
[0043] The third-level horizontal translation device 311 for the rightward movement of the glass tube should be located in the middle part of the horizontal translation device bracket 301. The remaining third-level horizontal translation devices 311 for the rightward movement of the glass tube, the second-level horizontal translation device 310 for the rightward movement of the glass tube, and the first-level horizontal translation device 309 for the rightward movement of the glass tube are translated 100 - 200 mm to the right in sequence to ensure the continuous rightward translation and conveyance of the glass tube to the right side of the horizontal translation device bracket 301. The right side of the third-level horizontal translation device 307 for the leftward movement of the glass tube is aligned with the right side of the first-level horizontal translation device 309 for the rightward movement of the glass tube. The remaining third-level horizontal translation devices 307 for the leftward movement of the glass tube, the second-level horizontal translation device 306 for the leftward movement of the glass tube, and the first-level horizontal translation device 305 for the leftward movement of the glass tube are translated 100 - 200 mm to the left in sequence to ensure the continuous leftward translation and conveyance of the glass tube to the left side of the horizontal translation device bracket 301.
[0044] In this embodiment, the glass tube conveyor belt 302 is provided with open grooves to better receive the glass tubes.
[0045] In this embodiment, glass tube horizontal translation limit plates 304 are provided on the left and right sides of the glass tube conveyor belt 302. The glass tube horizontal translation limit plates 304 are installed on the horizontal translation device bracket 301 through glass tube horizontal translation limit plate support columns 308 to prevent the horizontal translation device 3 from removing the glass tubes from the glass tube conveyor belt 302.
[0046] The working process of the present invention is as follows: Under the traction of the tractor 1, the glass tube moves forward and is cut into glass tubes of a certain length according to the actual situation. After being cut, the glass tube makes an oblique downward throwing motion under the action of its own inertia and gravity.
[0047] According to the traction speed of the glass tube, the rotation speed of the glass tube receiving roller 206 is adjusted to facilitate the smooth entry of the glass tube into the grooves between the glass tube receiving plates 2061. The buffer device support hollow shaft 212 is externally connected to an air source to supply air into the buffer air blowing pipe 211. Since the center of mass of the buffer air blowing pipe 211 is below the center line of the buffer air blowing pipe 211, when the glass tube receiving roller 206 rotates, the buffer air blowing pipe 211 remains stationary. When the buffer air blowing guide pipe 2112 in the buffer air blowing pipe 211 starts to overlap with the air outlet holes 2062 of the receiving roller, the buffer air flow flows out from the air outlet holes 2062 of the receiving roller and starts to generate an opposite acting force on the obliquely downward thrown glass tube to reduce the impact caused by the self-gravity and self-inertia of the glass tube. When the glass tube lands in the grooves between the glass tube receiving plates 2061 under the action of the buffer air flow, the speed of the air flow at the air outlet holes 2062 of the receiving roller is adjusted according to the length and diameter of the glass tube to ensure that the glass tube is located in the middle position of the glass tube receiving roller 206.
[0048] As the glass tube receiving plate 2061 rotates, the glass tube, under the support of the glass tube receiving plate 2061, moves rotationally downward along with the glass tube receiving plate 2061; due to the bend at the tail of the glass tube receiving plate 2061, the bend angle can be set to 30° - 50°, which can effectively reduce the falling speed of the glass tube; when the glass tube is a defective product, the electric push rod 201 extends to drive the glass tube baffle adjustment disc 204 to rotate, so that the glass tube baffle 205 remains vertical, preventing the defective glass tube from entering the glass tube slide plate 202. At this time, the angle between the glass tube baffle 205 and the top horizontal plane of the buffer device support 203 should be maintained at 80° - 90°.
[0049] When the glass tube meets the production requirements, the electric push rod 201 extends to drive the glass tube baffle adjustment disc 204 to rotate, so that the glass tube baffle 205 deflects towards the direction of the glass tube receiving roller 206, thus forming a transfer bridge between the glass tube receiving plate 2061 and the glass tube slide plate 202, and smoothly transferring the qualified glass tube to the glass tube slide plate 202; the angle between the glass tube baffle 205 and the top horizontal plane of the buffer device support 203 should be maintained at 30° - 60°.
[0050] Under the action of the self - gravity of the glass tube, the glass tube on the glass tube slide plate 202 slides along the glass tube slide plate 202 into the groove on the glass tube conveyor belt 302; according to the distance between the glass tube conveyor belt 302 and the glass tube along the glass tube slide plate 202, the telescopic length of the electric push rod 201 can be adjusted to adjust the angle between the glass tube slide plate 202 and the buffer device support 203; in order to prevent the glass tube from sliding down quickly and causing damage to the glass tube, the angle between the glass tube slide plate 202 and the top horizontal plane of the buffer device support 203 should be maintained at 5° - 20°.
[0051] When the length of the glass tube meets the maximum length required by production, the first - stage left - shift cross - transfer device 305 for glass tubes, the second - stage left - shift cross - transfer device 306 for glass tubes, the third - stage left - shift cross - transfer device 307 for glass tubes, the first - stage right - shift cross - transfer device 309 for glass tubes, the second - stage right - shift cross - transfer device 310 for glass tubes, and the third - stage right - shift cross - transfer device 311 for glass tubes are not started, and the glass tube moves along with the glass tube conveyor belt 302.
[0052] When the length of the glass tube is less than the maximum length required for production, the glass tube rightward first-stage transverse movement device 309, the glass tube rightward second-stage transverse movement device 310, and the glass tube rightward third-stage transverse movement device 311 are activated; the glass tube located at the middle position of the glass tube conveyor belt 302 first moves to the right side of the glass tube conveyor belt 302 under the clockwise rotation of the long transverse movement elastic column 316 and the short transverse movement elastic column 317 on the glass tube rightward third-stage transverse movement device 311; subsequently, under the further action of the glass tube rightward second-stage transverse movement device 310 and the glass tube rightward first-stage transverse movement device 309, it further moves to the right side of the glass tube conveyor belt 302 until it reaches the predetermined position; the long transverse movement elastic column 316 and the short transverse movement elastic column 317 have a certain elasticity, and the distance from them to the glass tube conveyor belt 302 should be 1 - 3 mm to provide sufficient power for the movement of the glass tube; after the glass tube reaches the rightmost side, the round-mouth operation of one end starts; in order to ensure the quality and time of the round-mouth operation, the distance between the glass tube rightward first-stage transverse movement device 309 and the glass tube leftward third-stage transverse movement device 307 should be 500 - 600 mm.
[0053] The glass tube leftward third-stage transverse movement device 307 uses the counterclockwise rotation of the long transverse movement elastic column 316 and the short transverse movement elastic column 317 to horizontally move the glass tube located on the right side of the glass tube conveyor belt 302 to the left side of the glass tube conveyor belt 302; subsequently, the glass tube leftward second-stage transverse movement device 306 and the glass tube leftward first-stage transverse movement device 305 further horizontally move the glass tube to the left side of the glass tube conveyor belt 302 until it reaches the predetermined position for the round-mouth operation of the other end.
[0054] Whether the glass tube moves left or right, a three-stage transverse movement strategy is adopted; the glass tube rightward third-stage transverse movement device 311 and the glass tube leftward third-stage transverse movement device 307 first achieve a large-distance horizontal movement of the glass tube, and the horizontal movement distance range is 500 - 700 mm; the horizontal movement distances of the glass tube leftward second-stage transverse movement device 306 and the glass tube rightward second-stage transverse movement device 310 are all reduced compared with those of the glass tube rightward third-stage transverse movement device 311 and the glass tube leftward third-stage transverse movement device 307, and the horizontal movement distance range is 300 - 600 mm; the horizontal movement distances of the glass tube rightward first-stage transverse movement device 309 and the glass tube leftward first-stage transverse movement device 305 for the glass tube are the smallest, and the horizontal movement distance range is 50 - 300 mm; by adjusting the running speed of the transverse movement conveyor belt 313, the precise translation of the glass tube is achieved.
[0055] To prevent the glass tube from having too large a horizontal movement amount and detaching from the glass tube conveyor belt 302, glass tube horizontal movement limit plates 304 are installed on both sides of the glass tube conveyor belt 302.
[0056] Through the cooperation of the transverse movement device, the present invention can horizontally move the ends of glass tubes of different lengths to the left and right sides of the production line for rounding operations, so as to adapt to the production of glass tubes of different lengths, improve the yield rate of glass tubes and reduce production costs.
