Technical Field

[0001] This utility model belongs to the technical field of glass tempering furnaces, specifically relating to a slag removal device for glass tempering furnaces. Background Technology

[0002] A glass tempering furnace is an industrial heating device that uses physical or chemical methods to form a compressive stress layer on the surface of the glass and a tensile stress layer inside. When the glass is subjected to external forces, the compressive stress layer can offset some of the tensile stress, preventing the glass from breaking and thus increasing the strength of the glass.

[0003] Existing methods for slag removal in glass tempering furnaces mostly involve manual cleaning after shutdown or simple mechanical scraping. However, manual cleaning requires shutdown and cooling, which affects production efficiency. On the other hand, a single slag removal mechanism is insufficient to remove all glass fragments and molten material adhering to the furnace rollers, resulting in poor cleaning performance and making it inconvenient for slag removal inside the glass tempering furnace.

[0015] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 3 The embodiments are described in detail below.

[0016] This embodiment provides a slag removal device for a glass tempering furnace, as shown in the attached diagram. Figure 1As shown, the assembly includes a mounting plate 1 and a horizontal support 2. The mounting plate 1 can be horizontally fixedly installed inside the glass tempering furnace. A first horizontal drive mechanism 3 is provided on the side of the mounting plate 1, and the movable end of the first horizontal drive mechanism 3 is driven to the horizontal support 2, which can move along the direction of the mounting plate 1. The first horizontal drive mechanism 3 can drive the horizontal support 2 to move laterally back and forth along the direction of the mounting plate 1, thereby adjusting the position of the overall mechanism below the horizontal support 2. A second horizontal drive mechanism 4 is provided on the lower surface of the horizontal support 2, and the movable end of the second horizontal drive mechanism 4 is driven to the translation support 5. The second horizontal drive mechanism 4 can drive the translation support 5 and the overall mechanism below it to move horizontally. In cooperation with the first horizontal drive mechanism 3, the scraping mechanism 8 and the cleaning mechanism 9 below can be arbitrarily adjusted in the horizontal direction. An electric push rod 6 is fixedly connected to the lower surface of the translation support 5, and the movable end of the electric push rod 6 is fixed to the horizontal position of the translation support 5. The lower support plate 7 is fixedly connected, and the electric push rod 6 can easily adjust the height of the slag scraping mechanism 8 and the cleaning mechanism 9. It works in conjunction with the first transverse drive mechanism 3 and the second transverse drive mechanism 4 to adjust the slag scraping mechanism 8 and the cleaning mechanism 9 freely within the three-dimensional moving space, so as to match the slag scraping mechanism 8 and the cleaning mechanism 9 with different furnace rollers. One side of the lower surface of the lower support plate 7 is provided with a slag scraping mechanism 8 that can scrape the molten slag on the surface of the furnace roller. The slag scraping mechanism 8 can fit against the top of the furnace roller. When the furnace roller rotates, the second transverse drive mechanism 4 drives the slag scraping mechanism 8 to scrape the molten slag on the surface of the furnace roller. The other side of the lower surface of the lower support plate 7 is provided with a cleaning mechanism 9 that can further clean the outside of the furnace roller. The cleaning mechanism 9 can brush and clean the slag on both sides of the furnace roller and can perform fine dust removal on the brushed parts to ensure the smoothness of the furnace roller surface, thereby ensuring the high-quality tempering of the glass.

[0017] In one alternative implementation, such as Figure 3 As shown, the slag scraping mechanism 8 includes a sleeve 801, a spring 802, a downward pressure rod 803, and an arc-shaped scraper 804. The sleeve 801 is fixedly connected to the lower surface of the lower support plate 7. The spring 802 is built into the inside of the sleeve 801, and the top end of the spring 802 is fixedly connected to the inner top wall of the sleeve 801. The downward pressure rod 803 is fixedly connected to the bottom end of the spring 802 and inserted into the inside of the sleeve 801. The sleeve 801, the spring 802, and the downward pressure rod 803 form a spring bar. There are at least two spring bars, and the arc-shaped scraper 804 is fixedly connected to the bottom end of several downward pressure rods 803. The spring bars provide elastic downward pressure on the arc-shaped scraper 804, which can ensure that the arc-shaped scraper 804 is pressed tightly against the outside of the furnace roller and has a certain dynamic range of motion, avoiding the increased risk of damage due to the rigid connection of the arc-shaped scraper 804.

[0018] In one alternative implementation, such as Figure 3As shown, the cleaning mechanism 9 includes a first motor 901, a drive gear 902, a driven gear 903, brush rods 904, and dust removal rods 905. The first motor 901 is fixedly mounted on the upper surface of the lower support plate 7, and the drive gear 902 is connected to the output end of the first motor 901 via a spline. There are two brush rods 904 and two dust removal rods 905, and the tops of both brush rods 904 and two dust removal rods 905 are fixedly connected to the driven gears 903. The brush rod 904 consists of an inner rod and an externally fixed brush sleeve with deformable capabilities. The brush sleeve is made of a compressible material with a certain friction. Both the brush sleeve and the dust removal cotton can be inserted into the gap between the two furnace rollers, and their sides are respectively in close contact with the furnace rollers on both sides. The direction between the two brush rods 904 and the two dust removal rods 905 corresponds to the direction of the mounting plate 1, and the direction between the brush rods 904 and the dust removal rods 905 corresponds to the direction of the transverse support 2. The driven gears 903 at the top of rod 904 and dust removal rod 905 mesh around the drive gear 902. The first motor 901 drives the drive gear 902 to rotate, which in turn drives the two brush rods 904 and dust removal rod 905 to rotate synchronously at high speed through the driven gears 903. The two brush rods 904 can be inserted into the gaps on both sides of the corresponding furnace rollers under the drive of the electric push rod 6, and the sides of the two brush rods 904 that are far apart from each other contact the sides of the adjacent furnace rollers on both sides. The two dust removal rods 905 are the same as the two brush rods 904. After the brush rods 904 and dust removal rods 905 are inserted into the gaps on both sides of the furnace rollers, they are driven to rotate at high speed by the first motor 901, while the furnace rollers are also rotating slowly. This allows the brush rods 904 on both sides to thoroughly brush the outside of the furnace rollers. By using frictional resistance, the residual slag that has been scraped off by the slag scraping mechanism 8 on the outside of the furnace rollers is brushed and cleaned at high speed, improving the cleaning effect of the slag on the outside of the furnace rollers. While cleaning, the top second transverse drive mechanism 4 can drive the slag scraping mechanism 8 and the cleaning mechanism 9 to move along the axis of the furnace roller, so that the slag scraping mechanism 8 can initially scrape off the molten slag on the outside of the furnace roller, while the high-speed rotating brushing bar 904 and dust removal bar 905 can sequentially brush and remove dust from the parts scraped by the arc-shaped scraper 804, thereby improving the cleaning effect of the furnace roller and ensuring that the furnace roller is smooth and clean overall.

[0019] In one alternative implementation, such as Figure 2As shown, the first transverse drive mechanism 3 includes a second motor 301 and a first lead screw 302. The first lead screw 302 is connected to the output end of the second motor 301 via a spline and is horizontally rotatably connected to the side of the mounting plate 1. There are two mounting plates 1, which are respectively set at both ends of the transverse bracket 2. A guide rod 10 is horizontally fixedly connected to the top of the side of the other mounting plate 1. A lead screw sleeve 11 is fixedly connected to one end of the transverse bracket 2 near the first lead screw 302, and the lead screw sleeve 11 is connected to the outside of the first lead screw 302 via a threaded drive. The transverse bracket 2 is close to the guide rod 10. One end of the guide rod 10 is fixedly connected to a sliding sleeve 12, which is slidably connected to the outside of the guide rod 10. The guide rod 10 can guide and limit the movement of the transverse support 2. The second motor 301 drives the first lead screw 302 to rotate, which can drive the transverse support 2 to move back and forth along the direction of the guide rod 10. The bottom of the two mounting plates 1 on the side close to each other is fixedly connected to a slide rail 13. The two ends of the transverse support 2 are slidably connected to the outside of the two slide rails 13, so that the transverse support 2 can only move horizontally back and forth along the direction of the slide rail 13, and can provide support for the transverse support 2.

[0020] In one alternative implementation, such as Figure 2 As shown, the second transverse drive mechanism 4 includes a third motor 401 and a second lead screw 402. The second lead screw 402 is connected to the output end of the third motor 401 via a spline and is horizontally rotatably connected to the bottom of the transverse support 2. The third motor 401 is fixedly installed on the side of the transverse support 2. When the third motor 401 drives the second lead screw 402 to rotate, it can drive the translation support 5 to reciprocate along the axial direction of the second lead screw 402, thereby adjusting the position of the lower structure in the direction of the furnace roller axis.

[0021] In one optional embodiment, limiting slide rods 14 are fixedly connected to both sides of the upper surface of the translation bracket 5, and limiting rods 15 are fixedly connected to the parts inside the transverse bracket 2 corresponding to the two limiting slide rods 14. The top ends of the two limiting slide rods 14 are respectively sleeved on the outside of the two limiting rods 15 and can move horizontally outside of them, which can limit and guide the translation bracket 5, ensuring that the third motor 401 drives the translation bracket 5 to move horizontally along the outside of the limiting rods 15 through the second lead screw 402.

[0022] The electric push rod 6, the first motor 901, the second motor 301 and the third motor 401 are all electrically connected to the external control unit and are all electrically connected to the external circuit through wires.

[0023] In summary, the slag removal device for glass tempering furnaces has the following operating steps: 1. When the internal temperature of the glass tempering furnace reaches a temperature that will not affect the operation of the equipment, the second motor 301 and the third motor 401 are started by the control unit. The second motor 301 drives the first lead screw 302 to rotate, and through the lead screw sleeve 11, it drives the transverse support 2 to move along the direction of the guide rod 10 and the slide rail 13, moving the transverse support 2 and all the mechanisms below it to the area directly above the target furnace roller that needs to be cleaned. The translation support 5 is initially located at the end of the transverse support 2. 2. The electric push rod 6 is activated by the control unit, which pushes the lower support plate 7 and the slag scraping mechanism 8 and cleaning mechanism 9 connected below it to descend as a whole until the arc-shaped scraper 804 of the slag scraping mechanism 8 is stably pressed against the top surface of the target furnace roller under the elastic force of the spring 802. The two brush rods 904 and the two dust removal rods 905 in the cleaning mechanism 9 are also inserted into the gap between the target furnace roller and the adjacent furnace roller. 3. Start the glass tempering furnace so that the furnace rollers begin to rotate slowly. At the same time, start the third motor 401 to drive the translation support 5 and the slag scraping mechanism 8 below to move slowly and uniformly along the axis of the furnace rollers. The rotation of the furnace rollers, combined with the axial movement of the slag scraping mechanism 8, allows the arc-shaped scraper 804 to scrape off most of the solidified slag on the surface of the furnace rollers. 4. When the third motor 401 starts, it also drives the first motor 901. The first motor 901 drives the drive gear 902 to rotate at high speed, which in turn drives the four driven gears 903 meshing with it to rotate. This causes the two brush rods 904 and the two dust removal rods 905 to start rotating at high speed. The high-speed rotating brush rods 904 brush the surface and sides of the furnace roller after slag scraping to remove the fine molten slag remaining after scraping. The high-speed rotating dust removal rods 905 follow closely behind to perform fine dust removal on the brushed area, further removing dust and making the surface of the furnace roller smooth. 5. When the device moves from one end of the furnace roller to the other end and completes the cleaning of the entire furnace roller, it controls each mechanism to disengage from the furnace roller and reset. Then, through the first transverse drive mechanism 3, it controls the slag scraping mechanism 8 and the cleaning mechanism 9 below to correspond with the other furnace roller and remove slag from the other furnace roller, thereby cleaning all the furnace rollers in sequence.

[0024] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
