Description

Technical Field

[0001] This utility model relates to the field of laminated glass technology, specifically a laminated glass pressing device with a stable structure. Background Technology

[0002] Laminated glass is a composite glass product consisting of two or more pieces of glass with one or more layers of organic polymer interlayer sandwiched between them. After special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure processes, the glass and interlayer are permanently bonded together.

[0003] When producing laminated glass, pressing is required to ensure that the bonding of each part of the laminated glass is more stable. However, the existing pressing device directly presses the glass surface through a hydraulic rod. During the operation, the pressing force is not uniform and the pressing mechanism is not stable, which affects the product quality. Utility Model Content

[0008] The telescopic ends of the electric push rods are all fixedly connected to a pressing mechanism, and the bottom of the base is longitudinally provided with a connecting groove, and a control mechanism is movably connected inside the connecting groove.

[0009] Furthermore, the pressing mechanism includes a connecting seat, a driving bar, a driving block, a lower pressing block, a pressing roller, and a connecting bar. The two ends of the driving block are movably connected to the opposite sides of the connecting seat through a set of left-right symmetrical rotating shafts. The driving bars are respectively sleeved on the outside of the rotating shafts connecting the driving block and the connecting seat. The two ends of the pressing roller are respectively movably connected to the opposite side of the driving bar away from the driving block through rotating shafts. The lower pressing blocks are respectively fixedly connected to the opposite sides of the driving bars, and the connecting bars are respectively sleeved on the outside of the rotating shafts connecting both ends of the lower pressing blocks.

[0010] Furthermore, both sides of the drive block are arc-shaped, and the lower pressing block has arc-shaped grooves on both sides away from the drive bar. The arc-shaped grooves are adapted to the corresponding drive block and pressing roller. The telescopic ends of the electric push rod are respectively fixedly connected to the top of the connecting seat.

[0011] Furthermore, each end of the connecting strip away from the pressing roller is movably connected to a pulley on its inner side. The pulley is slidably connected inside the groove, and the connecting strip is slidably connected to the base through the pulley and the groove.

[0012] Furthermore, the control mechanism includes a return spring, a steel cable, guide wheels, a drive wheel, and a connecting shaft. The drive wheels are fixedly connected to both ends of the connecting shaft. The guide wheels are located on the front and rear sides above the drive wheels, and are movably connected to the outer sides of the four corners of the base via rotating shafts. The middle position of the steel cable is attached to the hub of the drive wheel, and the other two ends of the steel cable slide through the hubs of the guide wheels and are fixedly connected to the outer sides of the connecting bar. The return spring is sleeved on both ends of the steel cable.

[0013] Furthermore, the control mechanism also includes a drive motor, a drive rod, a push bar, and a collar. The output end of the drive motor is fixedly connected to one side of the drive rod, and a set of positive and negative threads for driving are opened on the outer side of the drive rod. There are two push bars, and one end of each push bar is movably connected to the top of the collar through a rotating shaft. The other end of each push bar is movably connected to the outer side of the drive rod through positive and negative threads.

[0014] Furthermore, the bottom of the drive motor is fixedly connected to a mounting bracket, and the two ends of the mounting bracket are respectively fixedly connected to the inner sides of the base. The drive rod is movably connected to the inside of the connecting groove through a bearing. The connecting shaft is located laterally directly below the base, and a collar is fitted in the middle of the connecting shaft.

[0015] Compared with the prior art, this laminated glass pressing device with a stable structure has the following advantages:

[0016] I. This utility model uses a pressing mechanism to push the connecting seat downwards by controlling the telescopic end of the electric push rod. At this time, it is pulled by the connecting strip, causing the pressing roller to roll and press on both sides of the laminated glass surface until the drive strip is parallel to the laminated glass. At this time, the two sides of the drive block are placed inside the arc groove. Furthermore, the bottom of the lower pressing block and the drive block are close to and pressed on the surface of the laminated glass. This helps to ensure that air is discharged from each adhesive layer inside the laminated glass before pressing, avoiding any missed areas. Secondly, it ensures that the laminated glass is pressed with uniform force.

[0017] II. This utility model utilizes a control mechanism to drive a drive motor to rotate a drive rod. The drive rod, driven by the opposing threads, slides towards the opposite side at one end while simultaneously pushing the connecting shaft downwards via a collar at the other end. The drive wheel then pulls the steel cable downwards to the middle position, causing the connecting strips at both ends to move synchronously to both sides via pulleys. Simultaneously, a return spring compresses and contracts, causing the steel cable to slide along the guide wheel hub. This facilitates uniform speed control of the pressing roller, ensuring smooth and even pressing of the clamped glass. Furthermore, it reduces the difficulty of equipment operation and improves production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a laminated glass pressing device with a stable structure, including a base 1, with sliding grooves 2 on both sides of the base 1, and the sliding grooves 2 having a convex cross-section, a pressing groove 3 on the top surface of the base 1, and support frames 4 on the outer side of the base 1. A set of left-right symmetrical electric push rods 5 are fixedly connected to the top of the inner part of the support frame 4, and a pressing mechanism 6 is fixedly connected to the telescopic end of the electric push rods 5. A connecting groove 7 is longitudinally opened at the bottom of the base 1, and a control mechanism 8 is movably connected inside the connecting groove 7.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the pressing mechanism 6 includes a connecting seat 601, a drive bar 602, a drive block 603, a lower pressing block 604, a pressing roller 605, and a connecting bar 606. The two ends of the drive block 603 are movably connected to opposite sides of the connecting seat 601 via a set of symmetrical rotating shafts. The drive bars 602 are respectively sleeved on the outer side of the rotating shaft connecting the drive block 603 and the connecting seat 601. The two ends of the pressing roller 605 are movably connected to opposite sides of the drive bar 602 away from the drive block 603 via rotating shafts. The lower pressing block 604 is fixedly connected to opposite sides of the drive bar 602, and the connecting bar... 606 is respectively sleeved on the outer side of the connecting shaft at both ends of the lower pressure block 604. Both sides of the drive block 603 are arc-shaped, and the lower pressure block 604 has arc-shaped grooves 9 on both sides away from the drive bar 602. The arc-shaped grooves 9 are adapted to the corresponding drive block 603 and pressing roller 605. The telescopic ends of the electric push rod 5 are respectively fixedly connected to the top of the connecting seat 601. The inner side of the end of the connecting bar 606 away from the pressing roller 605 is movably connected to the pulley 10. The pulley 10 is slidably connected to the inside of the slide groove 2, and the connecting bar 606 is slidably connected to the base 1 through the pulley 10 and the slide groove 2.

[0027] By controlling the telescopic end of the electric push rod 5 to push the connecting seat 601 downward, it is pulled by the connecting strip 606, causing the pressing roller 605 to roll and press on both sides of the laminated glass surface until the drive strip 602 is parallel to the laminated glass. At this time, the two sides of the drive block 603 are placed inside the arc groove 9. Then, the bottom of the lower pressing block 604 and the drive block 603 are close to and pressed on the surface of the laminated glass. This helps to ensure that air is discharged from each adhesive layer inside the laminated glass before pressing, avoiding any missed areas, and also ensuring that the laminated glass is pressed with uniform force.

[0028] like Figure 2 , Figure 3 and Figure 4As shown, the control mechanism 8 includes a return spring 801, a steel cable 802, a guide wheel 803, a drive wheel 804, and a connecting shaft 805. The drive wheel 804 is fixedly connected to both ends of the connecting shaft 805. The guide wheels 803 are located on the front and rear sides above the drive wheel 804, and are movably connected to the outer sides of the four corners of the base 1 via rotating shafts. The middle position of the steel cable 802 is attached to the hub of the drive wheel 804, and the other two ends of the steel cable 802 slide through the hubs of the guide wheels 803 and are fixedly connected to the outer sides of the connecting bar 606. The return spring 801 is sleeved on both ends of the steel cable 802. The control mechanism 8 also includes a drive motor 806, a drive rod 807, a push bar 808, and a collar. 809, the output end of the drive motor 806 is fixedly connected to one side of the drive rod 807, and a set of positive and negative threads for driving are opened on the outer side of the drive rod 807. There are two push bars 808, and one end of each push bar 808 is movably connected to the top of the collar 809 through a rotating shaft. The other end of each push bar 808 is movably connected to the outer side of the drive rod 807 through positive and negative threads. The bottom of the drive motor 806 is fixedly connected to a mounting bracket 11, and the two ends of the mounting bracket 11 are respectively fixedly connected to the inner sides of the base 1. The drive rod 807 is movably connected to the inside of the connecting groove 7 through a bearing. The connecting shaft 805 is located laterally directly below the base 1, and the collar 809 is sleeved in the middle position of the connecting shaft 805.

[0029] The drive motor 806 drives the drive rod 807 to rotate, which in turn is driven by the positive and negative threads to make the drive rod 807 slide to the opposite side at one end and push the connecting shaft 805 vertically downward through the collar 809 at the other end. Then, the drive wheel 804 pulls the steel cable 802 to the middle position, so that its two ends pull the connecting strip 606 to move synchronously to both sides through the pulley 10. At the same time, the return spring 801 compresses and contracts, and the steel cable 802 slides along the hub of the guide wheel 803. This facilitates uniform speed control of the pressing roller 605, ensuring that it presses the clamped glass at a uniform speed and smoothly. In addition, it reduces the difficulty of equipment operation and improves equipment production efficiency.

[0030] Working principle: During use, the laminated glass to be pressed is placed inside the pressing groove 3. The drive motor 806 is then activated, causing the drive rods 807 to rotate. Driven by the opposing threads, the drive rods 807 slide towards each other at opposite ends, while at the ends closer together, they push the connecting shaft 805 downwards via the collar 809. Simultaneously, the drive wheel 804 pulls the steel cable 802 downwards to its middle position, causing both ends to pull the connecting strips 606 to move synchronously to both sides via the pulleys 10. When the reset spring 801 is compressed and contracted, the steel cable 802 slides along the hub of the guide wheel 803. During this process, the telescopic end of the synchronous control electric push rod 5 pushes the connecting seat 601 downward. At this time, it is pulled by the connecting bar 606, causing the pressing roller 605 to roll and press on both sides of the laminated glass surface until the drive bar 602 is parallel to the laminated glass. At this time, the two sides of the drive block 603 are placed inside the arc groove 9. Then, the bottom of the lower pressing block 604 and the drive block 603 are close to and pressed on the surface of the laminated glass.
