In this embodiment, the electric push rod as the material blocking driving device 122 drives the first material blocking block 123 to reciprocate with a small distance, which is beneficial to shortening the reciprocating time and improving the working speed.

In an alternative embodiment, the first stop block 123 is connected to the second stop block 125 through a linkage mechanism, the second stop block 125 is movably connected to the stop frame 121 through a stop block mounting member, the second stop block 125 has a first protrusion 127 at an end away from the first stop block 123, and the linkage mechanism is configured to drive the stop block to move so that the first protrusion 127 has different positions in a direction perpendicular to the sliding direction of the vacuum tube and/or in the sliding direction of the vacuum tube.

The second stopper block 125 is moved by the linkage mechanism so that the first protrusion 127 of the second stopper block 125 has different positions in a direction sliding along the vacuum tube or a direction perpendicular to the vacuum tube. The movement of the first material blocking block 123 can be converted into the movement of the second material blocking block 125, so as to block the vacuum tubes adjacent to the vacuum tube which falls through the falling hole 112, thereby avoiding the interference of falling of a plurality of vacuum tubes at one time to the subsequent tube falling process.

In an alternative embodiment, the material blocking block mounting member includes a material blocking block shaft 128, and the second material blocking block 125 is rotatably connected with the material blocking frame 121 through the material blocking block shaft 128.

By adopting the mode, the dead point problem of the connecting rod mechanism can not occur, and the transmission is simple and reliable.

In addition, in the present embodiment, the vacuum tube printing labeling machine further comprises a printing device 210, a pressing device, and a test tube rotating device, specifically, the test tube rotating device comprises a rotation driving motor 221 and a gear transmission device 222, and each rotating roller 223 is fixedly connected with one driven gear. The rotation driving motor 221 transmits power to the two rotation rollers 223 through the gear transmission device 222, and drives the driven gears of the two rotation rollers 223 to be engaged with the same transmission gear, so that the vacuum tube can be driven to rotate in the same direction in the printing process. The upper ends of the two rotating rollers 223 are lower than the lower surface of the vacuum tube receiving portion 201. In addition, the pressing device includes a pressing driving device 231, the pressing driving device 231 is connected with the pressing roller 233 through the pressing roller holder 232, and the pressing roller 233 is rotatably mounted on the pressing roller holder 232. The upper ends of the pressure roller holder 232 and the pressure roller 233 are lower than the lower surface of the vacuum tube receiving part 201. The pressing driving device 231 is used for driving the labeling press roller 233 to move in a direction far away from or close to the rotating rollers 223, when the labeling press roller 233 moves towards the vacuum tube, the two rotating rollers 223 and one labeling press roller 233 form a three-roller supporting structure to clamp the vacuum tube, then the vacuum tube can be driven to rotate, and the label printed by the printing device 210 is pasted into the vacuum tube along the circumferential direction of the vacuum tube in the rotating process. Further, the printing device 210 of the vacuum tube printing labeler may employ a printing device of an existing vacuum tube printing labeler, such as a label printer in CN1045555407A published on 12, 25/2014.

It should be noted that, in the drawings used in this embodiment, only one movable material blocking device is drawn for clarity of the drawings, in fact, the vacuum tube storage rack 110 shown in the drawings is provided with 8 oblique sliding grooves 111, one movable material blocking device is arranged corresponding to each oblique sliding groove 111, and in total, 8 movable material blocking devices are actually arranged, but considering that too many movable material blocking devices are drawn in the drawings, the drawing of too many vacuum tubes has no practical significance, but is not beneficial to clear expression, so only one row of vacuum tubes and one corresponding movable material blocking device are drawn.

The operation principle of the embodiment is as follows:

the vacuum tubes are stored in a row on the vacuum tube storage rack 110 as an initial state.

At this time, the output end of the blocking driving device 122 is in an extended state, so that the first blocking block 123 is in the first station, and the first blocking block 123 blocks a vacuum tube closest to the falling hole 112, so that the vacuum tube cannot slide down to the lower left in the drawing along the inclined sliding groove 111.

When the vacuum tube needs to be dropped, the output end of the stop driving device 122 moves upward, so that the second stop block 125 moves upward along with the vacuum tube and is located at the second station. Due to the action of the downward component force generated by gravity and no longer being obstructed by the first material blocking block 123, the vacuum tube closest to the falling hole 112 in the inclined chute 111 slides downward along the inclined chute 111 into the falling hole 112. Since the inner diameter of the drop hole 112 is greater than the maximum transverse dimension of the vacuum tube, the vacuum tube falls from the drop hole 112 into the funnel-shaped inlet chute 401 and then into the vacuum tube printing labelling machine.

While the first stopper 123 is ascending, the linkage shaft 124 ascends along with the first stopper 123, the linkage shaft 124 makes a movement away from the stopper shaft 128 in the linkage chute 126, and the second stopper 125 swings clockwise as shown in fig. 3 and 4. The first protrusion 127 descends, and the first protrusion 127 appears in the moving space of the vacuum tube on the inclined chute 111, and blocks the upper portion of the second vacuum tube from below in the inclined chute 111, and the state at this time is shown in fig. 4. While the lowermost vacuum tube falls, the second vacuum tube may be blocked from falling into the entry chute 401 with the first vacuum tube. The problem that a plurality of vacuum tubes fall into the inlet slide channel 401 at the same time is avoided, so that only one vacuum tube can be accurately controlled to fall into the vacuum tube printing and labeling machine in each action. The state of the movable stop device at this time is shown in fig. 4.

Before the vacuum tube is dropped into the vacuum tube printing labelling machine, the longitudinal positioning drive 202 is extended so that the transverse opening of the vacuum tube bearing 201 is located just below the outlet end of the inlet chute 401. Because the bottom of the vacuum tube body 301 is a hemisphere, the bottom of the vacuum tube can automatically guide after meeting the edge of the transverse opening part, so that the vacuum tube body 301 falls into the transverse opening part. The lower surface of the flange 302 will ride over the upper edge of the lateral opening.

After the presence of a vacuum tube in the lateral opening portion is detected by the vacuum tube detection element 203 disposed above the lateral opening portion. The power output end of the pressing driving device 231 extends out, and pressure is applied to the vacuum tube body 301 through the pressing roller support 232 and the pressing roller 233, so that the lower half part of the vacuum tube body 301 is pushed to an opening formed by the two parallel side-by-side rotating rollers 223, and the pressing roller 233 and the two rotating rollers 223 clamp the lower half part of the vacuum tube body 301 together. It should be noted that the gap left between the width of the transverse opening and the lower half of the vacuum tube body 301 is enough to make the lower half of the vacuum tube body 301 move relative to the transverse opening in the direction of the opening width of the transverse opening, so that the lower half of the vacuum tube body 301 is clamped by the pressing roller 233 and the two rotating rollers 223.

The rotation driving motor 221 starts to rotate, the two rotating rollers 223 are driven to rotate through the gear transmission device 222, the two rotating rollers 223 rotate in the same direction, and the compression roller 233 and the two rotating rollers 223 drive the vacuum tube body 301 to rotate together. Due to the rotation of the vacuum tube body 301, the contact part of the pressure roller 233 relative to the vacuum tube body 301 moves along the circumferential direction of the vacuum tube body 301, and the printed label can be gradually attached to the vacuum tube body 301 along the circumferential direction of the vacuum tube body 301 by the extrusion force of the pressure roller 233. As for the printing of the label, and the feeding roller (not shown in the drawing) in the printing apparatus 210 to feed the label out of the printing apparatus 210 to a position in contact with the vacuum tube or capable of being pressed against the vacuum tube by the pressing roller 233, it may be performed before the rotation of the vacuum tube is started. When the vacuum tube is rotated, the pressure roller 233 presses the label so that the label is subjected to an outward pulling force, and the label is rolled out by the vacuum tube and adhered to the vacuum tube body 301.

After the label is completely adhered to the vacuum tube body 301, the rotating roller 223 may continue to drive the vacuum tube body 301 to rotate for several turns, so as to compact the label adhered to the lower half portion of the vacuum tube body 301 by the pressing roller 233, or the rotating roller 223 may not continue to rotate. The longitudinal positioning driving device 202 drives the vacuum tube supporting portion 201 to withdraw, so that the edge of the transverse opening portion is no longer located on the lower surface of the flange 302, and the pressing driving device 231 drives the pressing roller 233 to be separated from the lower edge of the vacuum tube body 301 through the pressing roller support 232. The vacuum tube body 301 is not subjected to an upward supporting force nor a frictional force due to the pressing force of the pressing roller 233 and the rotating roller 223, so that the vacuum tube falls from the outlet of the vacuum tube printer and enters a subsequent processing apparatus.

When the presence of a vacuum tube in the lateral opening portion is detected by the vacuum tube detection element 203 disposed above the lateral opening portion, that is, after it has been confirmed that the vacuum tube has fallen into the vacuum tube printing labeler. The output end of the material blocking driving device 122 drives the first material blocking block 123 to move downwards, and at the same time, the linkage shaft 124 makes a motion in the material blocking chute close to the material blocking block shaft 128 and applies a downward acting force to the linkage chute 126, so that the second material blocking block 125 swings counterclockwise as shown in fig. 3 and 4. The first protrusion 127 is lifted up and separated from the movement space of the bulb body in the inclined chute 111, so that the bulb originally blocked by the first protrusion 127 can slide obliquely downward and slide to the position blocked by the first blocking block 123. The state of the movable stop device at this time is shown in fig. 3.

Then, the next cycle can be started. When the inclined sliding grooves 111 are multiple and multiple rows of vacuum tubes are stored in the vacuum tube storage rack 110, the movable material blocking devices corresponding to the inclined sliding grooves 111 where the vacuum tubes to be labeled are located can be controlled to act according to needs.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; for example:

in the first embodiment and the first variation, the second material blocking block is rotatably connected with the material blocking rack by using the material blocking block shaft, and actually, the second material blocking block is rotatably arranged relative to the material blocking rack, and the second material blocking block can be slidably connected with the material blocking rack. Specifically, the first material blocking block can be pivoted with a connecting rod, the connecting rod can also be pivoted with a second material blocking block, and the second material blocking block can slide along the direction perpendicular to the length of the vacuum tube. When the first material blocking block descends, the upper end of the connecting rod descends together with the first material blocking block, the lower end of the connecting rod can push the second material blocking block to move towards the vacuum tube along the direction perpendicular to the vacuum tube, the second material blocking block can block the vacuum tube like a gate, and the situation that the second vacuum tube falls together with the first vacuum tube from the lower side is avoided. When the first material blocking block is lifted, the connecting rod can pull the second material blocking block to be separated from the area of the vacuum tube when the vacuum tube slides. Or the second blocking block can be arranged to slide along the horizontal direction, and the connecting rod can push the second blocking block to slide towards the vacuum tube.

In the second variation and the first embodiment, the vertical movement of the first material blocking block is realized in a manner that the linkage shaft slides in the kidney-shaped hole of the second material blocking block, and actually, the vertical movement can be realized through a link mechanism. For example, when the first material blocking block moves downwards, the second material blocking block is pushed to rotate clockwise, that is, the upper part of the material blocking block is pushed to rotate towards the right side in fig. 3 and 4, and when the first material blocking block moves upwards, the second material blocking block is driven to rotate anticlockwise, and as in the embodiment, the first protruding part of the second material blocking block is used for blocking the falling of the second vacuum tube from the lower part.

In the third variant and the first embodiment, an electric push rod is adopted to drive the first material blocking block to vertically move, in fact, a steering engine or a rotary cylinder can be adopted to drive the first material blocking block to swing, and the first material blocking block can push the second material blocking block to swing through a connecting rod mechanism to switch the angle of the second material blocking block so as to block the second vacuum tube below. For example, the first material blocking block may be pivotally connected to a connecting rod, the connecting rod may also be pivotally connected to the second material blocking block, and a pivotal position of the second material blocking block and the connecting rod is located at an end of the second material blocking block away from the vacuum tube. The first material blocking block swings from the vertical state to the left side in the figures 3 and 4, the vacuum tube at the lowest part is allowed to slide downwards and fall from the falling hole, the connecting rod drives the pivoting part of the second material blocking block to swing to the left side, and the lower end of the second material blocking block swings to the right side in the figures, so that the second vacuum tube from the lower part is blocked.

In the fourth variant and the first embodiment, the electric push rod is used as a power source for driving the first material blocking block to move, and actually, the air cylinder can be used for realizing the vertical movement of the first material blocking block.

And the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
