Description

Technical Field

[0001] The invention relates to the field of glass processing clamping, in particular to a multi-station clamp for glass processing. Background Art

[0002] In the field of glass processing, the process of sealing the bottom of a single glass tube into two containers with bottoms has attracted much attention due to its efficient use of raw materials and increased production capacity. During the bottom sealing process, a clamp is used to hold the glass tube in place to ensure stability during processing. The clamp is also used in subsequent processing steps (such as cutting and edging) after the bottom sealing is completed.

[0003] When sealing the bottom of a glass tube, there is a common clamping and sealing operation method in the prior art: the glass tube is placed between two rotating rollers, and then the cylinder drives the squeezing plate to move downward so that the squeezing plate contacts the outer upper end of the straight tube glass. The glass tube is limited by the squeezing plate and the two rotating rollers. When performing the bottom sealing operation, the two rotating rollers rotate synchronously to drive the straight tube glass to rotate synchronously. At this time, the squeezing plate also rotates accordingly, and then the middle part of the glass tube is heated and softened, and the glass tube is stretched to the left and right at the same time to seal the bottom into two containers with bottoms.

[0004] However, this clamping method has certain drawbacks in practice. During the rotation and stretching of the glass tube, relying solely on the squeeze plate and two rotating rollers to limit and support the glass tube makes it difficult to ensure its stability during the rotation and stretching process. This can easily lead to radial force imbalance and vibration in the glass tube, which can cause uneven thickness at the bottom seal, affecting the sealing and strength of the container after sealing, and may even cause the bottom seal to fail. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present application provides a multi-station clamp for glass processing, which ensures the stability of the glass tube during stretching and movement by clamping the glass tube in a bidirectional, multi-point coordinated manner inside and outside when the glass is bottom-sealed, thereby ensuring the quality of the glass tube after bottom sealing.

[0036] The following is combined with Figure 1 - Figure 11 This application is described in further detail.

[0037] Please refer to Figure 1 and Figure 2 A multi-station fixture for glass processing includes a frame 1, with two guide rails 2 symmetrically distributed front and back disposed on the upper portion of the frame 1. A clamping mechanism 3 for clamping a glass tube 12 is disposed on both guide rails 2. The clamping mechanism 3 includes a movable plate 31 slidably disposed between the two guide rails 2. A plurality of rotating rollers 32 are rotatably mounted on each movable plate 31 to provide external support for the glass tube 12. A limit plate 33 is fixedly mounted on the side of the movable plates 31 adjacent to each other. Each limit plate 33 is equipped with a squeezing assembly 34 for squeezing the glass tube 12 and a supporting assembly 35 for internal support.

[0038] See Figure 1 and Figure 2 A motor 37 is fixedly provided on the side where the two movable plates 31 are away from each other. The output shaft of the motor 37 is connected to one end of one of the rotating rollers 32. The multiple rotating rollers 32 are connected through a pulley assembly. The end of the rotating roller 32 away from the movable plate 31 passes through the limit plate 33. Electric push rods 38 are provided on both sides of the upper part of the frame 1. The telescopic end of the electric push rod 38 is connected to the side of the movable plate 31 away from the limit plate 33.

[0039] See Figure 5 、 Figure 7 and Figure 8The support assembly 35 includes a mounting plate 351 rotatably mounted on the limiting plate 33, a U-shaped plate 352 is provided on the side of the mounting plate 351 close to the movable plate 31, a plurality of disks 353 with hollow structures are fixedly provided on the inner horizontal section of the U-shaped plate 352, three mounting blocks 354 are provided inside the disk 353, a slider 355 is slidingly provided inside the mounting block 354, and a support rod 356 is rotatably provided on the side of the slider 355 away from the movable plate 31.

[0040] See Figure 9 A rectangular opening is provided on the mounting plate 351 , in which a limit block 10 is fixedly provided. A rubber pad 11 is fixedly provided on the side of the limit block 10 away from the movable plate 31 .

[0041] When the bottom of the glass tube 12 is sealed, the electric push rod 38 can drive the movable plate 31 to slide on the guide rail 2. The movement of the movable plate 31 drives the limit plate 33 to move. The movement of the limit plate 33 drives the multiple support rods 356 to move synchronously (such as Figure 10 As shown in FIG, after the movable plate 31 moves to a suitable position, the multiple glass tubes 12 can be placed between the corresponding two rotating rollers 32, and the multiple support rods 356 at the corresponding positions on the left and right sides are all located on the inner side of the glass tube 12. Then, the electric push rod 38 continues to work to drive the limit plate 33 to move. When the rubber pad 11 on the limit block 10 contacts the end of the glass tube 12, the electric push rod 38 stops working, and the preliminary clamping and positioning of the glass tube 12 is completed.

[0042] See Figure 7 and Figure 8 A return spring 357 is fixedly installed inside the mounting block 354, and the end of the return spring 357 away from the mounting block 354 is connected to the slider 355. The mounting block 354 and the side of the disc 353 away from the movable plate 31 are both provided with a sliding opening for the support rod 356 to move.

[0043] See Figure 5 and Figure 6 A guide plate 5 symmetrically distributed front and back is fixedly provided on one side of the mounting plate 351 close to the movable plate 31, and a moving block 6 is slidably provided on the guide plate 5. The moving block 6 and the guide plate 5 are locked by bolts 7, and one side of the moving block 6 is fixedly connected to the U-shaped plate 352.

[0044] See Figure 2 、 Figure 5 and Figure 7A driving assembly 9 for driving the support rod 356 to move is provided on the U-shaped plate 352. The driving assembly 9 includes a cylinder 91 fixedly arranged on the horizontal section outside the U-shaped plate 352. A cross plate 92 is fixedly arranged on the telescopic end of the cylinder 91. A plurality of linkage plates 93 are fixedly arranged on the side of the cross plate 92 away from the cylinder 91. A moving rod 94 is fixedly arranged on the side of the linkage plate 93 close to the disc 353. The end of the moving rod 94 away from the linkage plate 93 passes through the interior of the disc 353 and is fixedly provided with a round table 95 used in conjunction with the slider 355.

[0045] See Figure 3 and Figure 4 The extrusion assembly 34 includes a slide rail 341 fixedly arranged on the side of the limiting plate 33 away from the movable plate 31, and an electric slider 342 is slidably arranged on the slide rail 341. The two electric sliders 342 are jointly fixed with a rectangular plate 343, and a plurality of vertical rods 344 are slidably arranged on the side of the rectangular plate 343 close to the limiting plate 33. A rectangular block 345 is fixedly arranged at the bottom of the vertical rod 344, and a return spring 346 is sleeved on the outer side of the vertical rod 344. The two ends of the return spring 346 are respectively connected to the rectangular plate 343 and the rectangular block 345. A connecting shaft 347 is fixedly arranged on the side of the rectangular block 345 away from the limiting plate 33, and an extrusion disk 348 is rotatably provided on the end of the connecting shaft 347 away from the rectangular block 345.

[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 release the lock on the moving block 6. At this time, the U-shaped plate 352 and the disc 353 move downward due to gravity. At this time, the support rod 356 moves downward with the disc 353 and does not contact the inner wall of the glass tube 12. Then the electric slider 342 works to drive the rectangular plate 343 to move downward. The downward movement of the rectangular plate 343 drives the squeezing plate 348 to move downward. When the squeezing plate 348 moves down to contact the outer upper end of the glass tube 12, the rectangular plate 343 stops moving, completing the preliminary limiting of the outer upper end of the glass tube 12.

[0047] Then the cylinder 91 works to push the horizontal plate 92 to move. The movement of the horizontal plate 92 drives the moving rod 94 to move through the linkage plate 93. The movement of the moving rod 94 drives the circular table 95 to move and squeeze the slider 355. After the slider 355 is squeezed, it squeezes the return spring 357 and drives the support rod 356 to move. The three support rods 356 gradually fit with the inner wall of the glass tube 12 during the movement. During the fitting process, the disc 353 and the U-shaped plate 352 will be driven to move further to adapt to the placement position of the glass tube 12, ensuring that the three support rods 356 can all fit closely with the inner wall of the glass tube 12. When the three support rods 356 are all tightly fitted with the inner wall of the glass tube 12, the outer lower end of the glass tube 12 is in contact with the rotating roller 32, and the disc 353 moves to be coaxial with the glass tube 12 (such as Figure 3As shown in FIG, the radial and axial position accuracy of the glass tube 12 is ensured, and the bolts 7 are then tightened to re-lock the movable block 6, thereby fixing the positions of the U-shaped plate 352, the circular disk 353, and the support rod 356. At this time, the support rod 356 supports the glass tube 12 from the inside, the squeezing disk 348 squeezes and limits the glass tube 12 from the outside upper end, and the rotating roller 32 supports the glass tube 12 from the outside lower end, thereby achieving a stable internal and external bidirectional, multi-point coordinated clamping of the glass tube 12. When sealing the bottoms of glass tubes 12 of the same size and the same batch, it is only necessary to adjust the use position of the support rod 356 before starting the bottom sealing. When sealing the bottoms of glass tubes 12 of the same size and the same batch, it is not necessary to adjust the use position of the support rod 356 again when sealing the bottoms of glass tubes 12 of the same size subsequently.

[0048] During bottom sealing, the motor 37 operates via a pulley assembly to drive the multiple rotating rollers 32 to rotate synchronously. The rotation of the rotating rollers 32 drives the glass tube 12 to rotate. As the glass tube 12 rotates, the squeezing plate 348 and the support rod 356 rotate synchronously. At the same time, the flame head of the frame 1 is turned on to spray flames toward the outer middle portion of the glass tube 12 to soften the middle portion of the glass tube 12. When the middle portion of the glass tube 12 is softened, the electric push rod 38 operates to drive the two movable plates 31 away from each other, applying a tensile force to the glass tube 12, gradually stretching the glass tube 12 at the softened portion. During this stretching process, the bidirectional internal and external support of the glass tube 12 effectively balances the radial forces acting on the glass tube 12, preventing the glass tube 12 from shaking due to lack of internal support during stretching. This ensures that the glass tube 12 remains stable during the rotation and stretching process, thereby ensuring the quality of the bottom sealing of the glass tube 12.

[0049] See Figure 5 、 Figure 6 and Figure 8 Two adjustment assemblies 36 for adjusting the position of the corresponding two mounting blocks 354 are provided on the side of the disc 353 away from the mounting plate 351. The mounting block 354 at the upper end of the disc 353 is fixedly connected to the inner wall of the disc 353. Two arc-shaped openings symmetrically arranged in front and back are opened on the side of the disc 353 away from the mounting plate 351. The adjustment assembly 36 includes an arc block 361 fixedly arranged in the arc opening. A connecting rod 362 is slidably arranged on the arc block 361. The end of the connecting rod 362 away from the movable plate 31 passes through the interior of the disc 353 and is connected to the corresponding mounting block 354. The outer side of the end of the connecting rod 362 away from the mounting block 354 is threaded and threaded with a fastening ring 363. The fastening ring 363 is tightly attached to the disc 353 on the side close to the disc 353.

[0050] See Figure 6A notch groove connected to the arc-shaped opening is provided on the disc 353 near the arc-shaped opening, and an indicator block 8 located in the notch groove is fixedly provided on the outer side of the connecting rod 362. 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 glass tubes 12 of different sizes with the rotating rollers 32 are different when placed between the corresponding two rotating rollers 32. When the cylinder 91 is operated so that the three support rods 356 are all in contact with the inner wall of the glass tube 12, the staff can then twist the fastening ring 363 on the connecting rod 362 to move it away from the disk 353, thereby canceling the limit on the connecting rod 362. The staff can then move the connecting rod 362 to slide on the arc block 361. The movement of the connecting rod 362 drives the corresponding mounting block 354 to move. The movement of the mounting block 354 can drive the corresponding support rod 356 to move along the inner wall of the glass tube 12, so that the support rod 356 moves to the corresponding position where the glass tube 12 contacts the rotating roller 32. The staff can then twist the fastening ring 363 again to make it tightly contact the outer side of the disk 353 to limit the connecting rod 362. By changing the position of the corresponding support rod 356, the glass tubes 12 of different sizes can continue to be stably supported internally.

[0052] When adjusting the use position of the connecting rod 362, the staff can refer to the scale on the disk 353 and the indicator block 8 on the connecting rod 362. By observing the relative position of the indicator block 8 and the scale, the accuracy of the position adjustment of the corresponding support rods 356 on multiple disks 353 can be more accurately ensured. Similarly, for the glass tubes 12 of the same size in the same batch, it is only necessary to adjust them before sealing the bottom. There is no need to adjust them again when processing the glass tubes 12 of the same size later.

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

[0054] When a glass tube 12 is sealed to form two bottomed containers, and the bottomed containers need to be cut or edged after subsequent cooling, the external driving component can drive the mounting plate 351 to rotate ninety degrees by using the rotating rod 4. The rotation of the mounting plate 351 drives the disc 353 and the support rod 356 to rotate ninety degrees (such as Figure 11As shown), the cooled bottomed container can be directly placed on the corresponding three support rods 356, and then the cylinder 91 can drive the support rods 356 to move and contact the inner wall of the bottomed container, so that the bottomed container can be clamped and fixed, and the cutting or edging of the bottomed container is facilitated. By rotating the support rods 356 to switch the use angle, the glass tube 12 (or the processed bottomed container) can be clamped and fixed in different steps of processing the glass tube 12.

[0055] During specific operation, when sealing the bottom of the glass tube 12, a clamp needs to be used to stably clamp it. The glass tube 12 can be placed on the corresponding two rotating rollers 32 first, so that the support rod 356 is located inside the glass tube 12. Then, the electric push rod 38 drives the movable plate 31 to move so that the rubber pad 11 on the limit block 10 fits with the end of the glass tube 12, completing the preliminary clamping and positioning of the glass tube 12.

[0056] Then, in order to provide stable support for the interior of the glass tube 12, the bolts 7 are loosened to release the lock on the movable block 6. The driving assembly 9 can be used to drive the corresponding three support rods 356 to fit the inner wall of the glass tube 12. At this time, the outer lower end of the glass tube 12 is in contact with the rotating roller 32, and the disk 353 is coaxial with the glass tube 12, ensuring the radial and axial position accuracy of the glass tube 12. The bolts 7 are then tightened to re-lock the movable block 6, thereby fixing the positions of the U-shaped plate 352, the disk 353 and the support rods 356. At this time, a two-way, multi-point coordinated and stable clamping of the glass tube 12 is achieved.

[0057] In order to make the clamp adaptable to glass tubes 12 of different sizes, the adjustment assembly 36 can be used to adjust the use position of the corresponding support rod 356 to ensure that when internally supporting glass tubes 12 of different sizes, the corresponding support rod 356 can be moved to the contact position between the glass tube 12 and the rotating roller 32, thereby achieving stable clamping of glass tubes 12 of different sizes.

[0058] Then, when sealing the bottom of the glass tube 12, the motor 37 works in conjunction with the pulley assembly to drive the rotating roller 32 and the glass tube 12 to rotate, the flame head sprays flame on the middle part of the glass tube 12 to soften it, and the electric push rod 38 drives the movable plates 31 to move away from each other to stretch the glass tube 12 to seal the bottom. During this stretching process, the force on the glass tube 12 in the radial direction is effectively balanced by providing internal and external bidirectional support for the glass tube 12, preventing the glass tube 12 from shaking due to lack of internal support during stretching, ensuring that the glass tube 12 always remains stable during the rotation and stretching process, thereby ensuring the quality of the bottom sealing of the glass tube 12.

[0059] In order to enable the clamp to meet the clamping requirements of different processing steps of the glass tube 12, after the bottom of the glass tube 12 is sealed to form a container with a bottom, the rotating rod 4 is driven by an external driving component to rotate ninety degrees, driving the mounting plate 351, the disc 353 and the support rod 356 to rotate, and the container with a bottom is placed on the support rod 356. The cylinder 91 drives the support rod 356 to move and contact the inner wall of the container with a bottom to complete the clamping and fixing, so as to perform cutting or edging processing, thereby improving the applicability of the clamp during use.
