[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] According to an embodiment of the utility model, an annealing furnace for glass products is provided.

[0025] Embodiment 1;

[0026] like Figure 1-5 As shown, the annealing furnace for glass products according to the embodiment of the utility model includes a mounting plate 1, on which a transmission structure 2 is installed, and the transmission structure 2 includes a support frame 204, and the support frame 204 is fixedly installed on the mounting plate 1, and a furnace body 3 is also fixedly installed on the support frame 204, and an adjustment structure 4 is installed on the top of the furnace body 3.

[0027] The mounting plate 1 is fixedly installed on the floor of the workshop, and the transmission structure 2 transmits the glass products so that the glass products can enter the furnace body 3 and be heated and annealed through the adjustment structure 4. At the same time, a certain temperature adjustment can be performed through the temperature control structure 5 and the transmission structure 2 can be preheated.

[0028] The transmission structure 2 includes a transmission belt 201, a transmission roller 202, a driving roller 203, a support frame 204, and a transmission slot 205. The transmission belt 201 is matched with a transmission roller 202, and a driving roller 203 is matched on one side of the transmission roller 202. The angle between the driving roller 203 and the transmission belt 201 is greater than one hundred and twenty degrees. The transmission roller 202 and the driving roller 203 are both installed on the support frame 204. The support frame 204 is provided with a transmission slot 205, and the transmission belt 201 is connected to the transmission slot 205.

[0029] The conveyor belt 201 is mainly driven by the motor of the driving roller 203, and supported and transmitted by the conveyor roller 202. The conveyor slot 205 on the support frame 204 facilitates the introduction of the conveyor belt 201 into the air inlet hood 501 of the temperature control structure 5, so that the conveyor belt 201 can be preheated to prevent the temperature difference between the conveyor belt 201 and the glass products from being too large to cause quality control problems. At the same time, the waste heat of the electric heater 408 can be utilized to maximize the utilization of its heat.

[0030] The adjustment structure 4 includes an adjustment plate 401, a support rod 402, a connecting plate 403, a connecting ear 404, an oblique support rod 405, a connecting seat 406, a hydraulic lifting rod 407, and an electric heater 408. The adjustment plate 401 is fixedly installed with a support rod 402, the support rod 402 is fixedly connected with a connecting plate 403, both sides of the connecting plate 403 are fixedly connected with connecting ears 404, the connecting ears 404 are fixedly connected with oblique support rods 405, the top of the oblique support rod 405 is fixedly connected with a connecting seat 406, the connecting seat 406 connects adjacent oblique support rods 405, the bottom end of the connecting seat 406 is installed with a hydraulic lifting rod 407, the driving end of the hydraulic lifting rod 407 is fixedly connected to the connecting seat 406, the bottom end of the adjustment plate 401 is fixedly connected with an electric heater 408, and the hydraulic lifting rod 407 is fixedly installed on the top of the furnace body 3.

[0031] The height of the hydraulic lifting rod 407 is adjusted by the driving end, so that the height of the connecting plate 403 can be adjusted through the connecting seat 406, the connecting ear 404 and the diagonal support rod 405. Since the connecting plate 403 is fixedly connected to the support rod 402 and the adjustment plate 401, the height of the adjustment plate 401 can be adjusted. The height of the adjustment plate 401 is adjusted by the electric heater 408. The electric heater 408 generates heat through electric energy and anneals the glass products on the conveyor belt 201 through thermal radiation. The support rod 402 and the furnace body 3 are connected in a sliding and sealed manner.

[0032] The temperature control structure 5 includes an air inlet cover 501 , an air outlet 502 , and an industrial fan 503 . The bottom end of the air inlet cover 501 is the air outlet 502 , and the air outlet 502 is connected to the industrial fan 503 .

[0033] The industrial fan 503 rotates to introduce the airflow in the furnace body 3 through the air inlet hood 501. Since the air inlet hood 501 is facing the conveyor belt 201, the temperature around the glass products is adjusted by controlling the fan to prevent them from overheating. At the same time, the hot air is guided by the industrial fan 503 and introduced into the conveyor belt 201 at the bottom through the air outlet 502. The conveyor belt 201 at the bottom is preheated without contacting the glass products, thereby reducing the temperature difference with the glass products and making full use of the waste heat.

[0034] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0035] In actual application, the mounting plate 1 is fixedly installed on the floor of the workshop, and the transmission structure 2 transmits the glass products so that the glass products can enter the furnace body 3 and be heated and annealed through the adjustment structure 4. At the same time, the temperature control structure 5 can be used to adjust the temperature and preheat the transmission structure 2. The transmission belt 201 is mainly driven by the motor of the driving roller 203, and is supported and driven by the transmission roller 202. The transmission groove 205 on the support frame 204 is convenient for introducing the transmission belt 201 into the air inlet hood 501 of the temperature control structure 5, so that the transmission belt 201 can be preheated to prevent the temperature difference between the transmission belt 201 and the glass products from being too large to cause quality control problems. At the same time, the waste heat of the electric heater 408 can be used to maximize the utilization of its heat. The hydraulic lifting rod 407 is adjusted by the height of the driving end to connect the connecting plate 403 through the connecting seat 406, the connecting ear 404 and the diagonal support rod 405. The height of the adjusting plate 401 can be adjusted. The connecting plate 403 is fixedly connected to the supporting rod 402 and the adjusting plate 401, so that the height of the adjusting plate 401 can be adjusted. The adjusting plate 401 is height-adjusted by the electric heater 408. The electric heater 408 generates heat by electric energy and anneals the glass products on the conveyor belt 201 by thermal radiation. The supporting rod 402 and the furnace body 3 are connected in a sliding and sealed manner. The industrial fan 503 rotates to introduce the airflow in the furnace body 3 through the air inlet cover 501. Since the air inlet cover 501 is facing the conveyor belt 201, the temperature around the glass products is adjusted by controlling the fan to prevent them from overheating. At the same time, the hot air is guided by the industrial fan 503 through the air outlet 502 to the conveyor belt 201 at the bottom. The conveyor belt 201 at the bottom is preheated without contacting the glass products, thereby reducing the temperature difference with the glass products and making full use of the waste heat.

[0036] The above description is only a preferred embodiment of the present invention and is 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.
