Description

Technical Field

[0001] The present invention relates to the technical field of glass tempering production, and specifically to a continuous glass tempering process and equipment. Background Art

[0002] Tempered glass is actually a kind of prestressed glass. To improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass bears external forces, the surface stress is first offset, thereby improving the bearing capacity and enhancing the advantages of the glass itself such as wind pressure resistance, cold and heat resistance, and impact resistance. The advantages of tempered glass are as follows: First, the strength is several times higher than that of ordinary glass, and the bending resistance is excellent; second, it is safe to use. Its increased bearing capacity improves the fragile property. Even if the tempered glass is damaged, it will break into small pieces without sharp corners, greatly reducing the damage to the surrounding environment when it breaks. The resistance to rapid cooling and heating of tempered glass is 3 - 5 times higher than that of ordinary glass. Generally, it can withstand a temperature difference change of more than 250 degrees Celsius, which has an obvious effect on preventing thermal cracking.

[0003] When continuously producing tempered glass, a glass tempering furnace is required. The glass tempering furnace is an important equipment in the glass processing process. However, if the heating time of the glass in the furnace is insufficient, the temperature in the furnace is uneven, or there are local defects in the glass itself, it is easy to cause the glass to break when it moves to the air grid for blowing and cooling; at the same time, when the glass is moving, if there is a sudden rigid contact or violent vibration, it is also easy to cause the glass to break. The broken glass accumulates under the air grid and on the discharge rollers, making it difficult to clean.

[0004] In order to achieve the purpose of facilitating the cleaning and collection of the broken glass, a continuous glass tempering process and equipment are provided. Summary of the Invention

[0016] A continuous glass tempering process, the specific steps are as follows:

[0017] Step 1: Heating, place the glass on the ceramic feeding roller in the feeding part. The ceramic feeding roller drives the glass into the heating part for heating. Heat the ordinary flat glass to a temperature close to its softening temperature of about 600 °C to release the thermal stress inside the glass;

[0018] Step 2: Tempering, the heated glass moves to the cooling part, and high-pressure cold air is sprayed on both sides of the glass through a multi-nozzle to quickly and evenly cool it to room temperature. This rapid cooling causes compressive stress on the glass surface and tensile stress inside, thereby improving the strength of the glass;

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By setting up a cleaning mechanism, the broken glass falls into the collection box for collection, and the motor runs to drive the movable frame to reciprocate; when the movable frame moves towards the discharge port, the scraper contacts the bottom end of the inner wall of the collection box, pushing the glass slag into the discharge port and falling into the collection box for collection operation; this design facilitates the collection of broken glass. When the movable frame moves towards the discharge port, the glass slag is scraped into the collection box for collection. When the movable frame moves away from the discharge port, the scraper separates from the bottom end of the collection box, preventing the glass slag from being pushed away from the discharge port.

[0022] 2. By setting up a positioning mechanism, the collection box is placed below the discharge port, and the positioning frame moves downward. The positioning frame moves into the inner wall of the collection box to position the collection box; when the positioning frame moves upward out of the collection box, the positioning of the collection box is cancelled, and at the same time, the two baffles rotate and contact each other to close the discharge port, facilitating the fixing and removal of the collection box for cleaning. Also, when the collection box is removed, it prevents the glass slag from falling from the discharge port. At the same time, after the collection box is removed, it prevents the scraper from contacting the bottom end of the inner wall of the collection box and pushing the glass slag to accumulate in the discharge port.

The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0037] A continuous glass tempering process, the specific steps are as follows:

[0038] Step 1: Heating. Place the glass on the ceramic feeding roller 5 in the feeding section 1. The ceramic feeding roller 5 drives the glass into the heating section 2 for heating. Heat the ordinary flat glass to a temperature close to its softening temperature of about 600 °C to release the thermal stress inside the glass.

[0039] Step 2: Tempering. The heated glass moves into the cooling section 3, and high-pressure cold air is sprayed onto both sides of the glass through a multi-nozzle to quickly and evenly cool it to room temperature. This rapid cooling causes compressive stress to be generated on the glass surface and tensile stress to be generated inside, thereby improving the strength of the glass.

[0040] Step 3: Discharging. The tempered glass is conveyed to the discharging section 4 through the ceramic feeding roller 5. The broken glass during cooling is collected by the cleaning mechanism 6.

[0041] Please refer to Figures 1 to 11 , in the embodiment of the present invention, a continuous glass tempering device includes a glass tempering furnace. The glass tempering furnace is divided into a feeding section 1, a heating section 2, a cooling section 3, and a discharging section 4. A ceramic feeding roller 5 for driving the glass to move is installed on the glass tempering furnace. The broken glass in the cooling section 3 and the discharging section 4 is collected by the cleaning mechanism 6.

[0042] The cleaning mechanism 6 includes a collection frame 601. The collection frame 601 is arranged below the cooling section 3 and the discharging section 4. One end of the bottom of the collection frame 601 is provided with a discharge port 602. A collection box 603 is arranged below the discharge port 602. A motor 604 is installed at one end of the collection frame 601. The output end of the motor 604 is connected to a first threaded rod 605. An activity frame 606 is slidably connected to the inner wall of the collection frame 601. The first threaded rod 605 penetrates through the activity frame 606. A scraping plate 607 is slidably connected to the bottom end of the activity frame 606. A second threaded rod 608 extending into the scraping plate 607 is rotatably connected inside the activity frame 606. The top end of the second threaded rod 608 is fixedly connected to a spur gear 609. An activity groove 610 is opened on the outer wall of the activity frame 606 on one side of the spur gear 609. A fixing groove 611 is opened at the top end of the activity groove 610. An activity plate 612 is slidably connected to the inner wall of the activity groove 610. A displacement plate 613 is slidably connected inside the activity plate 612. A first spring 614 is connected between the bottom end of the displacement plate 613 and the activity plate 612. The top end of the displacement plate 613 is fixedly connected to two symmetrically arranged fixing blocks 615 extending above the activity plate 612. Oblique grooves 616 are symmetrically opened on both sides of the displacement plate 613. Extrusion rods 617 extending out of the activity plate 612 are symmetrically slidably connected inside the activity plate 612. The position of the collection box 603 is positioned by a positioning mechanism 7.

[0043] In this embodiment: The broken glass on the cooling part 3 and the discharging part 4 falls into the collection frame 601 for collection. The motor 604 is started, and the rotation of the motor 604 drives the first threaded rod 605 to rotate. The rotation of the first threaded rod 605 drives the movable frame 606 to displace, and the motor 604 drives the movable frame 606 to reciprocate.

[0044] When the movable frame 606 moves towards the discharge port 602, the scraper 607 contacts the bottom end of the inner wall of the collection frame 601. The displacement of the movable frame 606 drives the scraper 607 to displace, and the displacement of the scraper 607 pushes the glass slag to move, pushing the glass slag into the discharge port 602 and falling into the collection box 603 for collection operation; then when the movable frame 606 moves to one end of the collection frame 601, the extrusion rod 617 first contacts the collection frame 601, pushing the extrusion rod 617 to displace. The displacement of the extrusion rod 617 drives the displacement plate 613 to displace, squeezing the first spring 614. The displacement of the displacement plate 613 drives the fixed block 615 to displace, and the fixed block 615 displaces out of the fixed groove 611, canceling the fixation of the movable plate 612. Then the movable plate 612 contacts the collection frame 601, pushing the movable plate 612 to slide in the movable groove 610 until the movable frame 606 moves to one end of the inner wall of the collection frame 601. During this process, the displacement of the movable plate 612 drives the spur gear 609 to rotate, and the rotation of the spur gear 609 drives the second threaded rod 608 to rotate. The rotation of the second threaded rod 608 drives the scraper 607 to move upward and separate from the bottom end of the inner wall of the collection frame 601; when the movable frame 606 moves away from the discharge port 602, the extrusion rod 617 separates from the collection frame 601, and the displacement plate 613 displaces under the elastic force of the first spring 614. The displacement of the displacement plate 613 drives the fixed block 615 to displace into the fixed groove 611 to fix the position of the movable plate 612; when the movable frame 606 moves to the other end of the collection frame 601, similarly, the movable plate 612 slides in the movable groove 610 again, driving the scraper 607 to move downward and contact the bottom end of the inner wall of the collection frame 601, facilitating the collection of the broken glass again. When the movable frame 606 moves towards the discharge port 602, the glass slag is scraped into the collection box 603 for collection. When the movable frame 606 moves away from the discharge port 602, the scraper 607 separates from the bottom end of the collection frame 601, preventing the missed glass slag from being pushed away from the discharge port 602.

[0045] Please refer specifically to Figures 7 to 11, the positioning mechanism 7 includes a positioning frame 701. The positioning frame 701 is slidably sleeved on the outer wall of the discharge port 602. The inner wall of the discharge port 602 is symmetrically and rotatably connected with baffles 702. The inner wall of the discharge port 602 is symmetrically and fixedly connected with limit blocks 703 below the baffles 702. The inner wall of the positioning frame 701 is symmetrically and fixedly connected with push frames 704. A third threaded rod 705 extending into the positioning frame 701 is rotatably connected inside the collection box 601. The top end of the third threaded rod 705 is fixedly connected with a first bevel gear 706. A second bevel gear 707 is rotatably connected to the outer wall of the first bevel gear 706 inside the collection box 601. One end of the second bevel gear 707 is fixedly connected with a rotating column 708. A fixing ring 709 is fixedly connected to the outside of the rotating column 708 at one end of the collection box 601. A clamping groove 710 is formed in the inner wall of the fixing ring 709. A clamping block 711 extending outside the rotating column 708 is slidably connected inside the rotating column 708. A second spring 712 is connected between the clamping block 711 and the rotating column 708. The positioning mechanism 7 further includes a cross bar 713. The cross bar 713 is slidably connected to the bottom end of the collection box 601. A horizontal groove 714 is formed at one end of the inner wall of the collection box 601. A shielding frame 715 extending into the inner cavity of the horizontal groove 714 is slidably connected inside the collection box 601. The shielding frame 715 is located at one end of the cross bar 713. A third spring 716 is connected between the shielding frame 715 and the collection box 601.

[0046] In this embodiment: When positioning the collection box 603, place the collection box 603 below the discharge port 602, push the clamping block 711 to displace, compress the second spring 712, the clamping block 711 displaces out of the clamping groove 710, cancel the fixation of the rotating column 708, rotate the rotating column 708, the rotating column 708 rotates to drive the second bevel gear 707 to rotate, the second bevel gear 707 rotates to drive the first bevel gear 706 to rotate, the first bevel gear 706 rotates to drive the third threaded rod 705 to rotate, the third threaded rod 705 rotates to drive the positioning frame 701 to displace downward, the positioning frame 701 displaces into the inner wall of the collection box 603 to position the collection box 603, so that the glass slag can enter the collection box 603 through the discharge port 602 for collection.

[0047] When removing the collection box 603, rotate the rotating column 708, the rotating column 708 rotates to drive the positioning frame 701 to displace upward, the positioning frame 701 displaces out of the collection box 603 to cancel the positioning of the collection box 603. At the same time, the positioning frame 701 moves upward, driving the push frame 704 to displace. The push frame 704 displaces and contacts the baffle 702, pushing the baffle 702 to rotate. The two baffles 702 rotate and contact each other to close the discharge port 602, preventing the glass slag from falling from the discharge port 602. This design facilitates the fixation and removal of the collection box 603 for cleaning, and prevents the glass slag from falling from the discharge port 602 when the collection box 603 is removed.

[0048] When the collection box 603 is taken out, the positioning frame 701 moves upward. The displacement of the positioning frame 701 pushes the cross bar 713 to displace. The displacement of the cross bar 713 pushes the shielding frame 715 to displace, squeezing the third spring 716 and canceling the shielding of the horizontal groove 714. When the movable frame 606 moves to one end away from the discharge port 602, the movable plate 612 can displace into the horizontal groove 714, thereby preventing the scraping plate 607 from moving downward to contact the bottom end of the collection frame 601. When the collection box 603 is positioned, the positioning frame 701 is separated from the cross bar 713, and the shielding frame 715 displaces under the elastic force of the third spring 716. The displacement of the shielding frame 715 shields the horizontal groove 714, thereby preventing the movable plate 612 from moving into the horizontal groove 714, enabling the movable plate 612 to displace and drive the scraping plate 607 to move downward to contact the bottom end of the collection frame 601, facilitating the prevention of the scraping plate 607 from contacting the inner wall bottom end of the collection frame 601 after the collection box 603 is taken out, and pushing the glass slag to displace and accumulate in the discharge port 602.

[0052] In this embodiment: The movable plate 612 slides in the movable groove 610 until the movable frame 606 moves to one end of the inner wall of the collection frame 601.
