Description

TECHNICAL FIELD

[0002] In the field of glass product processing, the process of processing a single glass tube into two containers with bottoms is concerned due to efficient use of raw materials and improved production capacity. When sealing the bottom of the glass tube, a clamp is used to clamp the glass tube to ensure its stability during processing. Meanwhile, the clamp is also used in subsequent processing procedures (notching or edge grinding, etc.) after the sealing of the bottom.

[0003] When sealing the bottom of the glass tube, a common clamping and sealing operation mode in the prior art is as follows: the glass tube is placed between two rotating rollers, then a cylinder drives the extrusion disc to move downward, so that the extrusion disc contacts the outer upper end of the straight tube glass, the glass tube is limited by the extrusion disc and the two rotating rollers, during the sealing operation, the two rotating rollers synchronously rotate to drive the straight tube glass to synchronously rotate, at this time, the extrusion disc also rotates, then the middle part of the glass tube is heated and softened, and the glass tube is stretched left and right to seal the bottom and process two containers with bottoms.

[0004] However, this clamping mode has certain deficiencies in application. During the rotation and stretching of the glass tube, only the extrusion disc and the two rotating rollers are used to limit and support the glass tube, which is difficult to ensure the stability of the glass tube during rotation and stretching, and may cause the glass tube to shake due to unbalanced force in the radial direction, thereby affecting the sealing and strength of the container after the bottom is sealed, and even causing the sealing to fail.

[0045] Referring to Figure 3 and Figure 4 , the extrusion assembly 34 comprises a sliding rail 341 fixedly arranged on the side of the limiting plate 33 away from the moving plate 31, the sliding rail 341 is slidably provided with a motor sliding block 342, the two motor sliding blocks 342 are fixedly provided with a rectangular plate 343, the side of the rectangular plate 343 close to the limiting plate 33 is slidably provided with a plurality of vertical rods 344, the bottom of the vertical rod 344 is fixedly provided with a rectangular block 345, the outer side of the vertical rod 344 is sleeved with a reset spring two 346, the two ends of the reset spring two 346 are connected with the rectangular plate 343 and the rectangular block 345 respectively, the side of the rectangular block 345 away from the limiting plate 33 is fixedly provided with a connecting shaft 347, and the end of the connecting shaft 347 away from the rectangular block 345 is rotatably provided with an extrusion disc 348.

[0046] In order to improve the stability of the glass tube 12 during the bottom sealing process, after the glass tube 12 is placed between the corresponding two rotating rollers 32, the bolt 7 is loosened to cancel the locking of the moving block 6, at this time, the U-shaped plate 352 and the disc 353 are moved downward under the action of gravity, at this time, the support rod 356 moves downward together with the disc 353 and does not contact the inner wall of the glass tube 12, then the motor sliding block 342 works to drive the rectangular plate 343 to move downward, the rectangular plate 343 moves downward to drive the extrusion disc 348 to move downward, when the extrusion disc 348 moves downward to contact the outer upper end of the glass tube 12, the rectangular plate 343 stops moving, and the preliminary limiting of the outer upper end of the glass tube 12 is completed.

[0047] Then the gas cylinder 91 works to push the horizontal plate 92 to move, the horizontal plate 92 moves to drive the linkage plate 93 to drive the moving rod 94 to move, the moving rod 94 moves to drive the circular table 95 to move to extrude the sliding block 355, the sliding block 355 is extruded to extrude the reset spring one 357 and drive the support rod 356 to move, the three support rods 356 gradually fit the inner wall of the glass tube 12 during the moving process, and the disc 353 and the U-shaped plate 352 are further moved during the fitting process to adapt to the placement position of the glass tube 12, so that the three support rods 356 can be closely fitted to the inner wall of the glass tube 12, when the three support rods 356 are closely fitted to the inner wall of the glass tube 12, at this time, the outer lower end of the glass tube 12 contacts the rotating roller 32, and the disc 353 moves to the same coaxial center as the glass tube 12 (such as Figure 3The glass tube 12 is guaranteed in radial and axial position accuracy, and then the bolt 7 is tightened to re-lock the moving block 6, so as to fix the position of the U-shaped plate 352, the disc 353 and the supporting rod 356, at this time, the glass tube 12 is supported from the inside through the supporting rod 356, the glass tube 12 is extruded and limited from the outside upper end by the extrusion disc 348, and the glass tube 12 is supported from the outside lower end by the rotating roller 32, so that the glass tube 12 is stably clamped in the inside and outside double-direction and multi-point cooperation, and for the glass tubes 12 of the same size in the same batch, the use position of the supporting rod 356 only needs to be adjusted before starting the bottom sealing, and the use position of the supporting rod 356 does not need to be adjusted again when the glass tubes 12 of the same size are sealed.

[0048] When the bottom is sealed, the motor 37 works to drive the rotating rollers 32 to rotate synchronously through the belt wheel assembly, the rotating rollers 32 drive the glass tube 12 to rotate, the extrusion disc 348 and the supporting rod 356 rotate synchronously when the glass tube 12 rotates, at the same time, the flame head of the rack 1 is opened to spray flame towards the middle part of the outer side of the glass tube 12 to soften the middle part of the glass tube 12, when the middle part of the glass tube 12 is softened, the electric push rod 38 works to drive the two moving plates 31 to move away from each other to apply a stretching force to the glass tube 12, so that the glass tube 12 is gradually stretched at the softened part, in the stretching process, the glass tube 12 is effectively balanced in the radial direction through the inside and outside double-direction support, so as to prevent the glass tube 12 from shaking due to lack of internal support when stretched, and ensure that the glass tube 12 always remains stable during rotation and stretching, thereby ensuring the quality of the bottom sealing of the glass tube 12.

[0049] Referring to Figure 5 , Figure 6 and Figure 8 , the disc 353 is provided with two adjusting assemblies 36 for adjusting the use positions of the two mounting blocks 354 away from the mounting plate 351. The mounting block 354 at the upper end in the disc 353 is fixedly connected with the inner wall of the disc 353, two arc-shaped openings symmetrically arranged in front and back are formed in the side of the disc 353 away from the mounting plate 351, the adjusting assembly 36 comprises an arc-shaped block 361 fixedly arranged in the arc-shaped opening, a connecting rod 362 is slidably arranged on the arc-shaped block 361, one end of the connecting rod 362 away from the moving plate 31 penetrates into the inside of the disc 353 and is connected with the corresponding mounting block 354, a threaded hole is formed in the outer side of the other end of the connecting rod 362 away from the mounting block 354, and a fastening ring 363 is threadedly arranged in the threaded hole, and the side of the fastening ring 363 close to the disc 353 is tightly attached to the disc 353.

[0050] Referring to Figure 6The disc 353 is provided with a notch groove in communication with the arc-shaped opening at a position close to the arc-shaped opening. The outer side of the connecting rod 362 is fixedly provided with an indicating block 8 located in the notch groove. The disc 353 and the guide plate 5 are both provided with scales on the side away from the mounting plate 351.

[0051] In order to stably clamp glass tubes 12 of different sizes, the contact positions of the glass tubes 12 of different sizes with the rotating rollers 32 are different when the glass tubes 12 are placed between the corresponding two rotating rollers 32. When the three supporting rods 356 are all in close contact with the inner wall of the glass tube 12 after the cylinder 91 works, the worker can then rotate the fastening ring 363 on the connecting rod 362 to move away from the disc 353, so as to cancel the limiting of the connecting rod 362. Then the connecting rod 362 can be moved to slide on the arc-shaped block 361. The movement of the connecting rod 362 drives the corresponding mounting block 354 to move, and the movement of the mounting block 354 can drive the corresponding supporting rod 356 to move along the inner wall of the glass tube 12, so that the supporting rod 356 is moved to the corresponding position of the contact position of the glass tube 12 with the rotating roller 32. Then the fastening ring 363 is rotated again to be in close contact with the outer side of the disc 353 to limit the connecting rod 362. Thus, by changing the position of the corresponding supporting rod 356, the glass tube 12 of different sizes can be stably supported from the inside.

[0052] During the adjustment of the use position of the connecting rod 362, the worker can refer to the scales on the disc 353 and the indicating block 8 on the connecting rod 362. By observing the relative position of the indicating block 8 and the scales, the accuracy of the position adjustment of the corresponding supporting rod 356 on the multiple discs 353 can be ensured more accurately. Similarly, for the same batch of glass tubes 12 of the same size, the adjustment can be completed before the bottom sealing, and the subsequent processing of the glass tubes 12 of the same size does not need to be adjusted again.

[0053] Referring to Figure 9 The upper part of the limiting plate 33 is provided with a rectangular groove, and the mounting plate 351 is located in the rectangular groove. The front and rear sides of the limiting plate 33 are both rotatably provided with rotating rods 4. The ends of the two rotating rods 4 close to each other are both fixedly connected with the mounting plate 351. One end of one of the rotating rods 4 is connected with an external driving component for driving the rotating rod 4 to rotate.

[0054] When the glass tube 12 is sealed at the bottom to form two containers with bottoms, and the containers with bottoms after cooling need to be subjected to processes such as cutting or edge grinding, the external driving component works to drive the mounting plate 351 to rotate by ninety degrees through the rotating rod 4. The rotation of the mounting plate 351 drives the disc 353 and the supporting rod 356 to rotate by ninety degrees (as shown in FIG. 6B). Figure 11After cooling, the container with bottom can be directly sleeved on the corresponding three supporting rods 356, and then the supporting rods 356 can be driven to move in contact with the inner wall of the container with bottom by the operation of the air cylinder 91, so that the container with bottom can be clamped and fixed, and then the container with bottom can be conveniently processed in a notch or an edge, and the supporting rods 356 can be rotated to switch the use angle, so that the glass tube 12 (or the processed container with bottom) can be clamped and fixed in different processes of processing the glass tube 12.

[0055] In particular, when the glass tube 12 needs to be clamped and fixed by the clamp during bottom sealing processing, the glass tube 12 can be first placed on the corresponding two rotating rollers 32, and the supporting rods 356 are located on the inner side of the glass tube 12, and then the rubber pad 11 on the limiting block 10 is brought into contact with the end of the glass tube 12 by the movement of the moving plate 31 driven by the electric push rod 38, so that the glass tube 12 is preliminarily clamped and positioned.

[0056] Then, in order to stably support the inside of the glass tube 12, the bolts 7 are loosened to cancel the locking of the moving block 6, and the corresponding three supporting rods 356 are brought into contact with the inner wall of the glass tube 12 by the driving assembly 9, at this time, the outer lower end of the glass tube 12 is in contact with the rotating roller 32, and the disc 353 is coaxial with the glass tube 12, which ensures the position accuracy of the glass tube 12 in the radial and axial directions, and then the bolts 7 are tightened to re-lock the moving block 6, so as to fix the positions of the U-shaped plate 352, the disc 353 and the supporting rods 356, thereby realizing the stable clamping of the glass tube 12 from inside and outside.

[0057] In order to make the clamp adapt to glass tubes 12 of different sizes, the use position of the corresponding supporting rod 356 can be adjusted by the adjusting assembly 36, so as to ensure that the corresponding supporting rod 356 can move to the contact position of the glass tube 12 and the rotating roller 32 when supporting the inside of the glass tube 12 of different sizes, thereby realizing the stable clamping of the glass tube 12 of different sizes.

[0058] Then, during the bottom sealing of the glass tube 12, the rotating roller 32 and the glass tube 12 are rotated by the motor 37 cooperating with the pulley assembly, the flame head softens the middle part of the glass tube 12 by spraying flame, and the moving plate 31 is driven by the electric push rod 38 to move away from each other to stretch the glass tube 12 to seal the bottom. During the stretching process, the glass tube 12 is effectively balanced in the radial direction by being supported from inside and outside, which prevents the glass tube 12 from shaking due to lack of internal support during stretching, ensures that the glass tube 12 remains stable during rotation and stretching, and thus ensures the quality of the bottom sealing of the glass tube 12.

[0059] In order to make the clamp meet the clamping requirements of different processing procedures of the glass tube 12, after the glass tube 12 is sealed to form a bottom container, the rotating rod 4 is driven to rotate 90 degrees by the external driving part, the mounting plate 351, the disc 353 and the supporting rod 356 are driven to rotate, the bottom container is sleeved on the supporting rod 356, the air cylinder 91 drives the supporting rod 356 to move to contact the inner wall of the bottom container to complete clamping and fixing, so that the notch or edge grinding processing is carried out, and the applicability of the clamp in the use process is improved.
