[0002] The glass heating device mainly uses physical or chemical methods to form a compressive stress layer on the surface of the glass and a tensile stress layer inside the glass, thereby achieving the purpose of improving the strength of the glass. The glass is heated to the softening temperature point through a glass tempering furnace, so that the particles in the glass have a certain migration ability and adjust the structure. Then the glass is blown and quenched, so that the glass produces a uniform and regularly distributed internal stress, thereby improving the strength of the glass.

[0034] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] refer to Figure 1-18 A hollow glass heating device includes a frame 1, a cleaning box 101, a heating chamber 102, and a cooling chamber 103 are sequentially arranged on the top of the frame 1, a feeding device is arranged in the frame 1, and the feeding device includes a synchronous pulley mechanism and a conveying roller mechanism. The cleaning box 101 is arranged on the top of the frame 1 and is located on the top of the synchronous pulley mechanism. The heating chamber 102 and the cooling chamber 103 are both arranged on the top of the frame 1 and are located on the top of the conveying roller mechanism. The synchronous pulley mechanism is arranged at the bottom of the cleaning box 101, which can prevent the synchronous belt from being affected by thermal expansion and contraction, thereby maintaining the stability of the synchronous belt, and further ensuring the stability and reliability of the transmission.

[0036] A cleaning roller 104 is rotatably connected inside the cleaning box 101, and a plurality of scrapers 105 for scraping dust off the surface of the insulating glass are provided on the cleaning roller 104, and each scraper 105 is circumferentially arranged with the cleaning roller 104 as the center. A driving component for switching the scrapers 105 back and forth is provided inside the cleaning box 101, and a cleaning mechanism for cleaning dust on the surface of the scrapers 105 after switching is provided inside the cleaning box 101.

[0037] Through the provided driving assembly and cleaning mechanism, the insulating glass is first placed on the synchronous pulley mechanism for transportation. When the insulating glass is transported to the inside of the cleaning box 101, the first scraper 105 will scrape the dust on the surface of the insulating glass. Subsequently, the insulating glass will enter the heating chamber 102 under the action of the synchronous pulley mechanism and the conveying roller mechanism. The cleaning roller 104 under the action of the driving assembly will automatically rotate a certain angle so that the other scraper 105 switches to the position of the first scraper 105. Since the surface of the other scraper 105 is clean, it will not cause secondary pollution to the surface of the subsequent insulating glass, thereby improving the cleaning efficiency of the scraper 105. At the same time, the provided cleaning mechanism will clean the dust on the surface of the switched scraper 105, so that the scraper 105 can be reused, thereby improving practicality.

[0038] Specifically, the synchronous pulley mechanism includes a first synchronous pulley 2, a second synchronous pulley 201, and a rotating motor 202. The first synchronous pulley 2 is arranged on a side of the frame 1 away from the cleaning box 101 and is rotatably connected to the frame 1. The second synchronous pulley 201 is arranged on a side of the frame 1 located inside the cleaning box 101, and the second synchronous pulley 201 is close to the heating chamber 102. The second synchronous pulley 201 is rotatably connected to the frame 1. The first synchronous pulley 2 is connected to the second synchronous pulley 201 through a first synchronous belt 203. The output end of the rotating motor 202 is fixedly connected to the first synchronous pulley 2. The transmission method of the synchronous pulley mechanism is to transmit through the meshing of gears. Power, compared with the traditional belt drive, there is no sliding, no sliding loss, and the transmission efficiency can be improved (a number of third synchronous pulleys can be set between the first synchronous pulley 2 and the second synchronous pulley 201, and the third synchronous pulleys are all rotatably connected to the frame 1, and each third synchronous pulley is connected to the first synchronous belt 203 and linked. Through the set third synchronous pulleys, when the operator places the insulating glass on the surface of the first synchronous belt 203, the third synchronous pulley can play a supporting role to prevent the insulating glass from collapsing on the surface of the first synchronous belt 203 due to excessive weight, thereby improving the stability of the first synchronous belt 203 when transporting the insulating glass).

[0039] The conveying roller mechanism includes a plurality of conveying rollers 204 and a power assembly that drives each conveying roller 204 to rotate at the same time. Each conveying roller 204 is respectively arranged on the other side of the frame 1 and is rotatably connected to the frame 1. Each conveying roller 204 is located at the bottom of the heating chamber 102 and the cooling chamber 103. The first synchronous pulley 2 has the same rotation direction as each conveying roller 204, and the horizontal height of the first synchronous belt 203 is equal to the horizontal height of each conveying roller 204. When in use, the insulating glass is placed on the surface of the first synchronous belt 203. The insulating glass enters the cleaning box 101 under the transportation of the first synchronous belt 203. After cleaning, one end of the insulating glass will contact the surface of the conveying roller 204. Under the action of friction, the insulating glass enters the heating chamber 102 for heating. After heating, the insulating glass enters the cooling chamber 103 for cooling under the push of the conveying roller 204, completing the final process.

[0040] The power assembly includes a drive motor 6. Each transport roller 204 is rotatably connected to the frame 1 via a fourth rotating shaft 602. Insulation blocks 601 are provided on both sides of the interior of the frame 1. Each fourth rotating shaft 602 extends into the insulation block 601 and is fixedly connected to a third gear 603. Each third gear 603 is connected via a second synchronous belt 604. The output end of the drive motor 6 is fixedly connected to the fourth rotating shaft 602. The rotation direction of the drive motor 6 is consistent with that of the rotating motor 202.

[0041] Furthermore, at least four scrapers 105 are provided, and each scraper 105 is fixedly connected to the cleaning roller 104. The driving assembly includes a first gear 3 and a plurality of racks 301 that rotate the first gear 3 a quarter of a turn, and each of the racks 301 is arranged at intervals (it should be noted that two or three scrapers 105 can be provided, but the length of the racks 301 must be set according to the number of scrapers 105. For example, if two scrapers 105 are provided, the length of the racks 301 needs to be sufficient to rotate the first gear 3 a quarter of a turn). The first gear 3 is arranged on the cleaning roller 104 and is fixedly connected to the cleaning roller 104. The rack 301 is arranged on the first synchronous belt 203, and the first gear 3 is meshed with the rack 301.

[0042] When in use, the operator needs to place the insulating glass between the two racks 301, and start the rotating motor 202 and the driving motor 6. The output end of the rotating motor 202 will drive the first synchronous pulley 2 to rotate clockwise, and the second synchronous pulley 201 will rotate clockwise under the action of the synchronous belt. At the same time, the first synchronous belt 203 will drive the insulating glass to move in the direction of the cleaning box 101. When the insulating glass moves into the cleaning box 101, the rack 301 at the front end of the first synchronous belt 203 will make the first gear 3 rotate a quarter of a turn, thereby achieving the purpose of switching the scraper 105. When the scraper 105 is switched into place, the scraper 105 will clean the dust on the surface of the insulating glass under the action of the first synchronous belt 203. When the insulating glass is separated from the scraper 105, the rack 301 set at the tail of the synchronous belt will engage with the first gear 3, so that the scraper 105 with dust is switched, and so on. In addition, in order to make the surface of the first synchronous belt 203 cleaner and tidier, a brush 10 is arranged on the side of the frame 1 away from the cleaning box 101, and the brush 10 is in contact with the surface of the first synchronous belt 203. When the first synchronous belt 203 is transported, the arranged brush 10 can brush off the dust on the first synchronous belt 203, thereby preventing the dust on the first synchronous belt 203 from adhering to the surface of the insulating glass, thereby improving the quality of the hot forming of the insulating glass.

[0043] The drive assembly in this embodiment does not require additional motors or other energy devices to drive the automatic switching of the scraper 105, thereby saving energy costs and equipment operating costs, while reducing operator intervention and improving production efficiency and production continuity.

[0044] In this embodiment, fixed boxes 302 are provided on both sides of the cleaning box 101, and each fixed box 302 is provided with a rotating groove 303 on one side close to the cleaning roller 104. A rolling bearing 304 is provided in the rotating groove 303. The outer ring of the rolling shaft is fixedly connected to the rotating groove 303, and the first rotating shaft 305 is fixedly connected to the inner ring of the rolling bearing 304. The rolling bearing 304 is a deep groove ball bearing. The deep groove ball bearing has a low friction coefficient, which can reduce energy loss during operation and improve the rotation efficiency of the cleaning roller 104.

[0045] A accommodating space 306 is provided on one side of the rotating groove 303 away from the rolling bearing 304, and one end of the first rotating shaft 305 extends into the accommodating space 306. The inner wall of the accommodating space 306 is provided with at least four slots 307 (it should be noted here that the number of the slots 307 needs to be set according to the number of scrapers 105. For example, if two scrapers 105 are provided, two slots 307 are also provided accordingly, and so on), and each slot 307 is circumferentially arranged with the first rotating shaft 305 as the center. The first rotating shaft 305 is arranged in the accommodating space 306. 06, and a slide groove 308 is provided on one end thereof, and close to the slot 307 on one side (the same structure can be provided on the other side of the first rotating shaft 305 to improve stability), the slide groove 308 is provided with a block 309 engaged with the slot 307, and an elastic component is provided at the bottom of the slide groove 308 to make the block 309 disengage from the slot 307. The elastic component can prevent the cleaning roller 104 from rotating due to excessive resistance between the insulating glass and the scraper 105, thereby improving the stability of the scraper 105 in cleaning the surface of the insulating glass and the cleaning efficiency.

[0046] Specifically, the elastic component includes a first elastic member 310 and a slider 311. The first elastic member 310 is a cylindrical compression spring. One end of the first elastic member 310 is fixedly connected to the bottom of the slide groove 308, and the other end of the first elastic member 310 is fixedly connected to the slider 311. The slider 311 is slidably connected to the inner wall of the slide groove 308. The block 309 is arranged on the side of the slider 311 away from the first elastic member 310 and is fixedly connected to the block 309. The cross-section of each slot 307 is a triangular structure (the specific shape of the slot 307 is a quadrangular pyramid), the side of the block 309 close to the slot 307 is an arc-shaped structure, and the block 309 is slidably connected to the slot 307.

[0047] When the scraper 105 cleans the surface of the insulating glass, the elastic component is provided to prevent the cleaning roller 104 from rotating. When the rack 301 meshes with the first gear 3, the first gear 3 rotates, thereby driving the first rotating shaft 305 to rotate. The first rotating shaft 305 only needs to overcome the force of the first elastic member 310 to drive the block 309 to disengage from the slot 307. The sliding connection of the slider 311 with the inner wall of the slide slot 308 can prevent the block 309 from being offset or misaligned during movement, improve the stability of the block 309 during movement, and ensure that the first elastic member 310 is evenly stressed, thereby increasing the service life of the first elastic member 310 (it should be noted that the elastic coefficient of the first elastic member 310 is greater than the resistance between the scraper 105 and the insulating glass, and less than the resistance of the meshing of the rack 301 and the first gear 3).

[0048] In this embodiment, the cleaning mechanism includes a dust box 4 and a cleaning block 401 for cleaning dust on the surface of the scraper 105 (bristles can be provided on the cleaning block 401 to improve the cleaning efficiency). The dust box 4 is arranged on the side of the cleaning roller 104 close to the heating chamber 102, and the dust box 4 is fixedly connected to the inner wall of the cleaning box 101 through a connecting frame 402. The side of the dust box 4 close to the cleaning roller 104 is rotatably connected to a dust guide plate 403 through a rotating shaft 404, and a dust guide plate 403 is sleeved on the rotating shaft 404. Torsion spring 405, dust guide plate 403 is tilted, the side of dust guide plate 403 away from dust box 4 abuts against the bottom of horizontally placed scraper 105, and the length of dust guide plate 403 is greater than the length of scraper 105, the top of dust box 4 is fixedly connected with accommodating block 407 through several supporting frames 406, cleaning block 401 is set on accommodating block 407 and slidably connected with accommodating block 407, and a traction mechanism is provided inside cleaning box 101 to enable cleaning block 401 to clean dust on the surface of scraper 105.

[0049] When the operator starts the traction mechanism, the traction mechanism will drive the cleaning block 401 to scrape the dust on the surface of the cleaning scraper 105, and the dust guide plate 403 will be abutted against the bottom of the scraper 105, which can prevent the scraped dust from falling on the surface of the synchronous belt, thereby improving the cleanliness of the synchronous belt surface. In addition, the dust guide plate 403 is tilted, so that the dust can automatically fall into the integrated box under the influence of gravity, thereby improving the dust collection efficiency. When the scraper 105 is switched, the scraper 105 will rotate the dust guide plate 403 around the rotating shaft 404, the torsion spring 405 will be twisted, and the dust on the dust guide plate 403 will automatically roll into the dust box 4 under the influence of gravity, further improving the dust collection efficiency, and facilitating the staff to clean the dust in a centralized manner. When the scraper 105 passes over the dust guide plate 403, the torsion spring 405 will quickly restore the deformation, thereby driving the dust guide plate 403 to reset.

[0050] Furthermore, the traction mechanism includes two winding components, the winding components include a traction rope 501, a winding wheel 502, a second gear 503, a sliding groove 504 is provided on the side of the accommodating block 407 close to the scraper 105, the sliding groove 504 is slidably connected with a sliding block 505, the cleaning block 401 is fixedly connected to the sliding block 505, and the second gear 503 in one of the winding components is rotatably connected to the inner wall of one side of the cleaning box 101 through the second rotating shaft 506, and the center distance between the second gear 503 and the first gear 3 is greater than the length of the rack 301, and the second gear 503 is arranged on the side opposite to the cleaning block 401, The second gear 503 is meshed with the rack 301, and the winding wheel 502 is rotatably connected to the inner wall of the cleaning box 101 through the third rotating shaft 507. The second rotating shaft 506 and the third rotating shaft 507 are connected by a speed increasing mechanism. One end of the traction rope 501 is fixedly connected to the sliding block 505, and the other end of the traction rope 501 is fixedly connected to the winding wheel 502 through the pulley 11. Another winding assembly is arranged on the inner wall on the other side of the cleaning box 101, and the center distance between the two winding assemblies is greater than the length of the rack 301. The two winding assemblies have the same structure, and the traction rope 501 in the other winding assembly is fixedly connected to the sliding block 505.

[0051] The speed increasing mechanism comprises a first conveyor pulley 508 and a second conveyor pulley 509. The diameter of the first conveyor pulley 508 is twice the diameter of the second conveyor pulley 509. The first conveyor pulley 508 is arranged on the second rotating shaft 506 and is fixedly connected to the second rotating shaft 506. The second conveyor pulley 509 is arranged on the third rotating shaft 507 and is fixedly connected to the third rotating shaft 507. The first conveyor pulley 508 and the second conveyor pulley 509 are connected by a conveyor belt 510. When the second rotating shaft 506 rotates one circle driven by the second gear 503, the first conveyor pulley 508 will rotate one circle, and the second conveyor pulley 509 will rotate two circles driven by the conveyor belt 510. The second conveyor pulley 509 will drive the winding wheel 502 to rotate two circles through the third rotating shaft 507 (it should be noted that the winding wheel 502 has a sufficient circumference to enable the traction rope 501 to drive the cleaning block 401 to clean the surface of the scraper 105).

[0052] When the rack 301 is meshed with the second gear 503, the second gear 503 will rotate one circle counterclockwise, the second shaft 506 will rotate one circle counterclockwise under the drive of the second gear 503, the first conveyor pulley 508 will rotate one circle counterclockwise, and the second conveyor pulley 509 will rotate two circles counterclockwise under the drive of the conveyor belt 510, and the second conveyor pulley 509 will drive the winding wheel 502 to rotate two circles counterclockwise through the third shaft 507. When the winding wheel 502 rotates, the traction rope 501 will drive the cleaning block 401 to move so that the cleaning block 401 cleans the surface of the scraper 105. When the rack 301 is disengaged from the second gear 503, the rack 301 will continue to move forward. When the rack 301 is meshed with the second gear 503 in another winding assembly, similarly, the winding wheel 502 will rotate two circles counterclockwise, so that the traction rope 501 drives the sliding block 505 to return to the original state. The same applies when the next rack 301 meshes with the second gear 503. In addition, the traction mechanism in this embodiment does not require an additional motor or other energy device to drive the cleaning block 401 to clean the surface of the scraper 105, thereby saving energy costs and equipment operating costs, while reducing operator intervention and improving production efficiency and production continuity.

[0053] Working principle:

[0054] When in use, the operator needs to place the insulating glass between the two racks 301 and start the rotating motor 202 and the driving motor 6. The output end of the rotating motor 202 will drive the first synchronous pulley 2 to rotate clockwise, and the second synchronous pulley 201 will rotate clockwise under the action of the synchronous belt. At the same time, the first synchronous belt 203 will drive the insulating glass to move toward the cleaning box 101. When the insulating glass moves into the cleaning box 101, the rack 301 at the front end of the first synchronous belt 203 will cause the first gear 3 to rotate a quarter of a turn, thereby achieving the purpose of switching the scraper 105. When the scraper 105 is switched into place, the first synchronous belt 203 will cause the insulating glass to continue to move forward. When the surface of the insulating glass contacts the scraper 105, the scraper will clean the dust on the surface of the insulating glass.

[0055] After cleaning is completed, the insulating glass will continue to move forward under the transportation of the first synchronous belt 203. When the rack 301 on the first synchronous belt 203 engages with the second gear 503, the second gear 503 will rotate counterclockwise for one circle, and the second rotating shaft 506 will rotate counterclockwise for one circle under the drive of the second gear 503. The first conveyor pulley 508 will rotate counterclockwise for one circle, and the second conveyor pulley 509 will rotate counterclockwise for two circles under the drive of the conveyor belt 510. The second conveyor pulley 509 will drive the winding wheel 502 to rotate counterclockwise for two circles through the third rotating shaft 507. When the winding wheel 502 rotates, the traction rope 501 will drive the cleaning block 401 to move in the sliding groove 504 so that the cleaning block 401 cleans the surface of the scraper 105. At the same time, the winding wheel 502 in the winding assembly arranged on the other side of the cleaning box 101 will relax, so that one end of the traction rope 501 moves with the cleaning block 401. When the rack 301 is disengaged from the second gear 503, the rack 301 will continue to move forward, and when the rack 301 is meshed with the second gear 503 in another winding assembly, similarly, the winding wheel 502 will rotate counterclockwise for two turns to wind up the traction rope 501, so that the traction rope 501 drives the sliding block 505 back to the original state. The same is true when the rear rack 301 is meshed with the second gear 503. The dust scraped off by the cleaning block 401 will fall into the dust box 4 through the dust guide plate 403, which is convenient for the operator to collect. After cleaning, one end of the insulating glass will contact the surface of the transport roller 204, and under the action of friction, the insulating glass enters the heating chamber 102 for heating. After heating, the insulating glass enters the cooling chamber 103 for cooling under the push of the transport roller 204, thereby completing the final process.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
