The sliding driving piece 42 is in the embodiment in a mode of setting a motor to match with a worm gear reducer, and correspondingly, a rack matched with the motor is arranged on the cutting table 1, a gear meshed with the rack is coaxially fixed through an output shaft of the worm gear reducer, and the driving seat 41 is driven to slide relatively on the cutting table 1 through controlling the forward and reverse rotation of the motor. In addition, the driving seat 41 and the cutting table 1 may be matched by various linear modules or sprocket transmission to realize sliding connection of the driving seat 41, which is not described herein.

The cutter tube 65 is fixed on the cutter seat 62 in a tight manner and extends towards the direction close to the driving clamping mechanism 4, and a cutter 66 with a downward cutter edge is arranged on one side, away from the cutter seat 62, of the cutter tube 65 in a detachable connection manner, and the cutter 66 is used for abutting against the inner wall of the glass tube to score the inner wall of the glass tube.
Generally, when a glass tube is waiting to be cut, the cutter holder 62 is first lifted by the lifting driving member 63 so that the cutter tube 65 can be inserted into the glass tube without contacting the inner wall of the glass tube, and then the cutter holder 62 is controlled by the lifting driving member 63 to slide downward, so as to drive the cutter 66 on the cutter tube 65 to contact the inner wall of the glass tube, and the glass tube rotates relative to the glass tube under the mutual cooperation of the driving and clamping mechanisms 4, so that the cutter 66 scores the inner wall of the glass tube.

And in the process of driving the cylinder to return, the compression spring 67 can play a role of buffering the lowering of the cutter seat 62, so that the cutter 66 is prevented from directly striking the glass tube. In general, the cutter 66 on the cutter tube 65 is worn and gradually passivated as the apparatus is repeatedly cut, so that the pressure applied to the compression spring 67 by the cutter holder 62 needs to be changed by artificially increasing the number of the weights 69 as the apparatus is used for a longer period of time.
Referring to fig. 1 and 4, further, a rotary support mechanism 7 for supporting the scoring position of the glass tube is provided on the cutting table 1 at the cutting station, and the rotary support mechanism 7 includes a synchronizing plate 71, a plurality of rotary disks 72 rotatably connected to the synchronizing plate 71, and a support driving device for driving the synchronizing plate 71 to lift.

Referring to fig. 3 and 4, it should be noted that when the cutter 66 is scribing the inner wall of the glass tube, the portion of the rotating disc 72 supporting the glass tube needs to be located directly below the cutter 66, i.e. the force applied by the cutter 66 to the glass tube and the supporting force applied by the rotating disc 72 to the glass tube are located on the same vertical plane.
Referring to fig. 4, as an alternative embodiment, the rotation support mechanism 7 may be provided on the cutting table 1 in total with two. One of the rotary supporting mechanisms 7 is used for being matched with the cutting knife mechanism 6, and the other rotary supporting mechanism 7 is used for supporting one end of the glass tube far away from the driving clamping mechanism 4. Wherein, a rotatory supporting mechanism 7 for supporting glass pipe one end can slide through the slide rail and closely fix fixed cooperation mode and wholly slide and connect on cutting table 1, and then can change the interval between two rotatory supporting mechanism 7 through adjusting this part, and then can adapt to the glass pipe with the different required cutting length of cooperation.
Referring to fig. 1 and 4, the flaming mechanism 5 includes a support bracket 51 provided on the cutting table 1, a rotary driving member 52 provided on the support bracket 51, and a flaming assembly 53 provided on a driving end of the rotary driving member 52, the flaming assembly 53 having a flaming head 531 flaming downward to face the glass tube and a detection switch 532 for detecting whether the glass tube is deficient. The support bracket 51 slides on a sliding rail connected with the driving clamping mechanism 4 in a sliding way, and the support bracket 51 further realizes relative fixation relative to the cutting table 1 in a fastening way. One side of the support bracket 51 extends upward, and the rotary driving member 52 is fixed at the portion extending upward, the rotary shaft of the rotary driving member 52 extends horizontally, the vertical plane of the rotary shaft is perpendicular to the axial direction of the glass tube, and the space between the flaming component 53 and the cutting table 1 is used for the glass tube to pass through.
Thus, the rotary driving member 52 drives the flame spraying assembly 53 to rotate as a whole, and in a preferred embodiment, the rotary driving member 52 rotates by 90 ° in a stroke, that is, after the rotary driving member 52 operates, the flame emitted by the flame spraying head 531 is far away from the glass tube and is sprayed in a substantially horizontal direction, and when the flame spraying assembly 53 operates, the flame sprayed by the flame spraying head 531 is directed against the glass tube and is sprayed in a substantially vertical direction.
Referring to fig. 4 and 5, it should be noted that the flame-spraying heads 531 should be disposed in a staggered manner with respect to the rotary supporting mechanism 7, and as a preferred embodiment, the flame-spraying heads 531 are located at a side far from the driving clamping mechanism 4 with respect to the rotary supporting mechanism 7, that is, after the glass tube is scored by the cutter mechanism 6, the driving clamping mechanism 4 should be relatively advanced toward a direction close to the cutting station, so that the scored portion is opposite to the flame-spraying heads 531.
Referring to fig. 1, 6 and 7, the structure of the feeding mechanism 2 and the structure of the discharging mechanism 3 are similar, each of the feeding mechanism and the discharging mechanism comprises a base bracket 21 and a connecting bracket 22 which is connected to the base bracket 21 in a sliding manner in the vertical direction, a transferring bracket 23 is connected to the upper side of the connecting bracket 22 in a sliding manner in the horizontal direction, a vertical driving piece 24 for driving the connecting bracket 22 to slide in the vertical direction is connected between the base bracket 21 and the connecting bracket 22, and a transverse driving piece 25 for driving the transferring bracket 23 to slide in the horizontal direction is connected between the connecting bracket 22 and the transferring bracket 23. The sliding connection mode between the connection bracket 22 and the base bracket 21 and the sliding connection between the transfer bracket 23 and the connection bracket 22 can be realized by adopting a sliding rail and sliding block type sliding mode.
The transition support 23 is used for supporting the glass tube, a plurality of transition limiting grooves 231 used for limiting the glass tube to roll are formed in the upper end face of the transition support 23 at equal intervals along the driving direction of the transverse driving piece 25, transition supporting pieces 26 located on two sides of the transition support 23 are arranged on the base support 21, the transition supporting pieces 26 are used for supporting two ends of the glass tube, and a plurality of transition limiting grooves 261 used for limiting the glass tube to roll are formed in the upper end face of the transition supporting pieces 26 at equal intervals along the driving direction of the transverse driving piece 25. As a preferred embodiment, the transition limit groove 261 and the transition limit groove 231 are both triangular grooves so that both side groove walls thereof can be simultaneously contacted with the outer surface of the glass tube, and the interval between adjacent transition limit grooves 231 is the same as the interval between adjacent transition limit grooves 261.
In this arrangement, when the vertical driving member 24 drives the connecting bracket 22 to move up to the top dead center, the bottom surface of the transfer limiting groove 231 needs to be higher than the upper end surface of the transition receiving member 26, and when the vertical driving member 24 drives the connecting bracket 22 to move down to the bottom dead center, the bottom of the transition limiting groove 261 needs to be higher than the upper end surface of the transfer bracket 23. Specifically, when the vertical driving member 24 drives the connecting bracket 22 to go up to the top dead center, the glass tube is relatively fixed on the transferring bracket 23, and the glass tube on the transferring bracket 23 can be driven by the transverse driving member 25 to move relatively relative to the transition receiving member 26. When the vertical driving member 24 descends to the bottom dead center, the glass tube is relatively separated from the transfer bracket 23 and relatively fixed with the transition receiving member 26, and at this time, the transfer bracket 23 moves relative to the glass tube by driving the transverse driving member 25. Furthermore, by the cooperation of the vertical driving piece 24 and the horizontal driving piece 25, the glass tube can be advanced step by step relative to the base bracket 21, thereby realizing the transportation of the glass tube.
However, it should be noted that the conveying direction of the feeding mechanism 2 is opposite to that of the discharging mechanism 3, that is, the feeding mechanism 2 drives the glass tube to approach the feeding station step by step, and the discharging mechanism 3 drives the glass tube to move step by step in a direction away from the cutting station. In addition, the transfer rack 23 of the loading mechanism 2 needs to be movable above the cutting table 1, and when the transfer rack 23 moves above the cutting table 1, it waits for the clamping mechanism 4 to be driven to clamp the glass tube. Similarly, the transfer rack 23 of the blanking mechanism 3 is required to be movable above the cutting table 1, and when the glass tube is waiting to be cut, the transfer rack 23 is required to be positioned below the glass tube to wait for receiving the cut glass tube. The vertical driving member 24 and the horizontal driving member 25 may be one or more of an air cylinder, an oil cylinder and a linear motor, and the specific installation manner is a conventional technical means provided by those skilled in the art, which is not described herein.
With reference to fig. 7, further, the transition receiving members 26 on both sides may be connected to the base frame 21 in a sliding connection manner, so that the glass tubes with different lengths may be better supported by changing the interval between the transition receiving members 26 on both sides. In general, the glass tube used as the raw material input to the loading station is generally fixed in length, while the length of the glass tube after cutting is changed, so that the transition receiving piece 26 can be arranged in a sliding connection manner only on the blanking mechanism 3.
Referring to fig. 1 and 2, in addition, a lifting support mechanism 8 is disposed on the cutting table 1 and on the traveling track of the driving clamping mechanism 4, and a plurality of lifting support mechanisms 8 may be disposed opposite to each other and arranged on the cutting table 1 at intervals. The lifting support mechanism 8 comprises a support plate 81 sliding in the vertical direction relative to the cutting table 1, a groove 82 for the glass tube to penetrate is formed in the upper end of the support plate 81, and sliding of the support plate 81 relative to the cutting table 1 can be achieved through driving modes of an air cylinder, an oil cylinder and even a linear motor. When the driving clamping mechanism 4 does not pass through the lifting supporting mechanism 8, the supporting plate 81 slides upwards relative to the cutting table 1 so that the supporting plate 81 contacts with the bottom surface of the glass tube, and the glass tube is relatively limited in the groove 82 formed above the supporting plate 81. When the driving clamping mechanism 4 approaches the lifting support mechanism 8 and is ready to pass through the lifting support mechanism 8, the corresponding support plate 81 descends to be separated from the glass tube, and at this time, the lifting support mechanism 8 does not influence the normal movement of the driving clamping mechanism 4, i.e. the support plate 81 is separated from the horizontal movement track of the driving clamping mechanism 4.
Referring to fig. 2 and 4, the cutting table 1 is further provided with a guide hopper 9 for receiving waste material at both ends of the glass tube, and as a preferred embodiment, one guide hopper 9 is located between adjacent rotary support mechanisms 7, and the other guide hopper 9 is located at a side of the lifting support mechanism 8 away from the cutting station. In the initial stage of processing the glass tube, the flame mechanism 5 and the cutter mechanism 6 first partially slit one end of the glass tube to level it, and the partial waste falls into the hopper 9 located between the adjacent rotary support mechanisms 7. After the glass tube has been cut successively, the drive of the gripping mechanism 4 is reversed, and the grippers 43 loosen the remaining waste and drop it into the hopper 9 during the passage of the other hopper 9.
As an alternative, the glass tube fixed-length cutting apparatus disclosed in the present application can process two or even more glass tubes at the same time, so that the number of the groups of the clamping head 43 on the driving clamping mechanism 4, the groove 82 on the lifting supporting mechanism 8, the fire head 531 on the fire mechanism 5, the rotating disc 72 on the rotating supporting mechanism 7, and the cutter tube 65 are set to be the number corresponding to the simultaneous processing number of the glass tubes, and the number of the groups of the transfer limiting grooves 231 for limiting the glass tubes when the feeding mechanism 2 and the discharging mechanism 3 extend above the cutting table 1 are also equal accordingly.
The implementation principle of the glass tube fixed-length cutting equipment provided by the embodiment of the application is as follows: firstly, the glass tube is manually placed in the feeding mechanism 2, the feeding mechanism 2 transfers the glass tube into the feeding mechanism 2 step by step and waits for the driving clamping mechanism 4 to clamp, after that, as the clamping of the glass tube by the driving clamping mechanism 4 is completed, the supporting plate 81 in the lifting driving mechanism can support the glass tube, and the transferring bracket 23 of the feeding mechanism 2 can be retracted into the feeding mechanism 2. Then, the clamping mechanism 4 is driven to move the whole glass tube to the cutting station, and when the other end of the glass tube moves into the cutting station, the rotary supporting mechanism 7 acts to support the glass tube by the rotary plate. The cutter mechanism 6 then extends the cutter 66 into the glass tube and scores a score in the glass tube by cooperating with the rotation of the glass tube driven by the driving clamping mechanism 4, and after scoring is completed, the cutter mechanism 6 retreats and the glass tube is driven by the driving clamping mechanism 4 to continue to advance to wait for the subsequent operation of the flame spraying mechanism 5. Thereafter, the rotary driving member 52 is operated to heat the flame emitted from the flame-spraying head 531 in alignment with the scribing portion, the scribing portion is broken by rapid temperature rise, and the waste material at one end of the glass tube is dropped into the guide hopper 9. Then, the clamping mechanism 4, the cutter mechanism 6 and the fire spraying mechanism 5 are driven to be matched with each other continuously to cut the glass tube into a required length, but at this time, the transferring support 23 of the blanking mechanism 3 is inserted to receive the cut glass tube, and then the cut glass tube is transferred out of the cutting station through the action of the blanking mechanism 3.
It should be noted that the glass tube transferred out through the blanking mechanism 3 can be matched with other equipment to adapt to automatic production, and the cut fixed-length glass tube can also be transferred into other processing equipment in a manual storage mode.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
