Description

Technical Field

[0001] This utility model relates to the field of tempered glass production technology, and in particular to a device for preventing glass from clogging the tempering furnace. Background Technology

[0002] There are various designs and implementation methods for devices to prevent glass from clogging the tempering furnace's air vents. These devices generally include the tempering furnace body, conveyor rollers, mounting base, air vent assembly, monitoring and alarm components, and breakage components. This device can promptly alarm and automatically handle glass blockage at the furnace outlet, preventing glass from becoming stagnant and trapped inside the furnace, and ensuring that any glass shards that shatter can be quickly and safely disposed of.

[0003] Chinese utility model patent application number 201720087865.5 proposes a device to prevent glass from clogging the furnace vents of a tempering electric furnace. The device includes a roller conveyor frame, transmission rollers, an electric furnace vent, a photoelectric emitter group, a PLC controller, and an opening mechanism. The photoelectric emitter group consists of a first photoelectric emitter and a second photoelectric receiver. Several transmission rollers are rotatably fixed side-by-side on the roller conveyor frame. The electric furnace vent is fixed above the transmission rollers. Both the first photoelectric emitter and the second photoelectric receiver are fixed on the roller conveyor frame, with the first photoelectric emitter and the second photoelectric receiver facing each other. A pair of first photoelectric emitters and second photoelectric receivers is arranged directly below each electric furnace vent. The PLC controller is connected to both the first photoelectric emitter and the second photoelectric receiver, and is also connected to the opening mechanism. When the second photoelectric receiver does not receive the radiation emitted by the first photoelectric emitter, it transmits a signal to the PLC controller, which then controls the opening mechanism to open.

[0004] However, in this technical solution, the glass transport is suspended when blockage needs to be cleared, which affects the efficiency of glass tempering. In addition, when the glass spontaneously breaks, it produces small fragments that may fall onto adjacent glass. The device cannot clean up the smaller glass fragments that fall onto the glass, thus affecting the glass's entry into the next process and consequently affecting the efficiency of glass tempering.

[0005] Therefore, it is necessary to solve the above problems by means of a device that prevents glass from clogging the tempering furnace. Utility Model Content

[0006] The purpose of this invention is to provide a device for preventing glass from clogging in a tempering furnace, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for preventing glass from clogging the tempering furnace air vent, comprising a support frame, on which a transport component and a turning component are provided, and on which a tempering box and an air vent box are also provided, with a cleaning component provided on the side of the air vent box away from the tempering box, and the glass body is placed on the transport component and the turning component.

[0008] The cleaning assembly includes a sliding plate, a scraper fixedly mounted on the bottom of the sliding plate, and a buffer spring mounted on the side of the sliding plate near the outlet of the air grating box.

[0009] Preferably, sliders are fixedly provided at both ends of the translation plate, and a sliding groove is provided on the inner side of the air grating box. The sliders are engaged in the sliding groove and slide back and forth along the sliding groove.

[0010] Preferably, the end of the buffer spring away from the translation plate is fixedly connected to a fixing plate, and the fixing plate is fixedly connected to the inner side of the air grating box.

[0011] Preferably, the flipping assembly includes a passive roller, with rotating arms rotatably mounted at both ends of the passive roller, and a short shaft fixedly mounted at the end of the rotating arm away from the passive roller.

[0012] Preferably, the short shaft is rotatably mounted on the support frame, and a rotary motor is fixedly connected to the end of the short shaft away from the rotating arm. A fixing frame is fixedly mounted on the outside of the rotary motor, and the fixing frame is fixedly mounted on the support frame.

[0013] Preferably, the transport assembly includes a drive roller with both ends rotatably mounted on a support frame, and a gear is fixedly connected to either end of the drive roller, with a chain wound around the circumference of the gear.

[0014] Preferably, a transport motor is fixedly connected to the gear located on the far side, and the transport motor is fixedly mounted on the support frame by a mounting bracket.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, a cleaning component is set up to clean up the glass fragments generated by the spontaneous breakage of adjacent glass on the glass body. At the same time, it can also identify the broken glass blocking the air grille box, thereby controlling the flipping component to flip the congested broken glass and make it fall off the transport component. There is no need to stop the transport component to transport the glass body before clearing the blockage, thus ensuring the efficiency of glass tempering.

[0017] 2. In this utility model, by setting a translation plate and a buffer spring, the translation plate sweeps away glass fragments on the glass body; at the same time, when there are accumulated glass fragments, they will abut against the translation plate and push it to move, thereby compressing the buffer spring. At this time, the flipping component is controlled to flip the accumulated glass fragments off, ensuring that the intact glass body can be continuously transported, avoiding the need to stop the machine to clear the blockage of the air grid box, which would affect the tempering 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] To address the problems in existing technologies where glass transport needs to be paused during unblocking, affecting the efficiency of glass tempering, and where the device cannot clean up fine glass shards that fall onto the glass, thus affecting the glass's entry into the next process and consequently the efficiency of glass tempering, the following embodiments are proposed.

[0026] This utility model provides, for example Figures 1 to 5The device shown is for preventing glass from clogging the tempering furnace air vent. It includes a support frame 1, on which a transport component 2 and a turning component 6 are mounted. A recycling box can be installed directly below the transport component 2 and the turning component 6 to collect glass fragments and debris. The support frame 1 is also equipped with a tempering box 3 and an air vent box 4. The air vent box 4 is located at the outlet of the tempering box 3. A cleaning component 5 is installed on the side of the air vent box 4 away from the tempering box 3. The glass body 7 is placed on the transport component 2 and the turning component 6.

[0027] By setting up the cleaning component 5 to clean up the glass fragments generated by the spontaneous breakage of adjacent glass on the glass body 7, it can also identify the broken glass blocking the air grille box 4, thereby controlling the flipping component 6 to flip the congested broken glass and make it fall off the transport component 2. There is no need to stop the transport component 2 to transport the glass body 7 before clearing the blockage, thus ensuring the efficiency of glass tempering.

[0028] like Figures 2-3 As shown, the cleaning component 5 is located at the outlet of the air grating box 4. The cleaning component 5 includes a sliding plate 501, and a scraper 502 is fixedly installed at the bottom of the sliding plate 501. The scraper 502 is located five millimeters above the glass body 7 to facilitate the removal of debris from the glass body 7. A buffer spring 503 is installed on the side of the sliding plate 501 near the outlet of the air grating box 4. Slider blocks are fixedly installed at both ends of the sliding plate 501. A sliding groove is opened on the inner side of the air grating box 4. The sliders are engaged in the sliding groove and slide back and forth along the sliding groove. A fixing plate 504 is fixedly connected to the end of the buffer spring 503 away from the sliding plate 501. The fixing plate 504 is fixedly connected to the inner side of the air grating box 4.

[0029] like Figure 4 As shown, the flipping assembly 6 includes a passive roller 601, with rotating arms 602 rotatably mounted at both ends of the passive roller 601. A short shaft 603 is fixedly mounted at the end of the rotating arm 602 away from the passive roller 601. The short shaft 603 is rotatably mounted on the support frame 1. A rotary motor 604 is fixedly connected to the end of the short shaft 603 away from the rotating arm 602. A fixing frame 605 is fixedly mounted on the outside of the rotary motor 604. The fixing frame 605 is fixedly mounted on the support frame 1.

[0030] When in use, as the glass body 7 with shards on its surface passes under the scraper 502, the scraper 502 blocks the shards on the glass body 7. As the glass body 7 is continuously transported by the transport assembly 2, the shards are swept away by the scraper 502 and fall from between the drive rollers 201 into the recycling box. During this process, the buffer spring 503 hardly generates any compression, or only generates slight compression.

[0031] When the buffer spring 503 is compressed, and the compression gradually increases, it indicates that there is glass blockage at the outlet of the air grille box 4, with glass fragments accumulating. This will push the translation plate 501 along the slide rail, thereby compressing the buffer spring 503. At this time, if... Figure 5 As shown, the rotary motor 604 is reversed, which drives the rotating arm 602 to rotate upward through the short shaft 603. This causes the passive roller 601 to rotate upward around the short shaft 603, thereby turning over the congested glass fragments. After the passive roller 601 is turned up, a larger gap is formed, and the glass fragments fall into the recycling box from the gap, thus completing the clearing of the glass blockage. At the same time, there is no need to stop the transportation of the intact glass body 7, ensuring the efficiency of glass tempering.

[0032] By setting up a translation plate 501 and a buffer spring 503, the translation plate 501 sweeps away glass fragments on the glass body 7; at the same time, when there are accumulated glass fragments, they will abut against the translation plate 501 and push it to move, thereby compressing the buffer spring 503. At this time, the control flipping component 6 flips the accumulated glass fragments to ensure that the intact glass body 7 can be continuously transported, avoiding the need to stop the machine to clear the blockage of the air grid box 4, which would affect the tempering efficiency.

[0033] like Figure 5 As shown, there are two transport components 2. One transport component 2 is located below the tempered glass box 3. The glass inside the tempered glass box 3 needs to be moved back and forth for heating, so it is controlled separately from the transport component 2 below the air grille box 4. The other transport component 2 is located below the air grille box 4. The transport component 2 includes a drive roller 201. Both ends of the drive roller 201 are rotatably mounted on the support frame 1. A gear 202 is fixedly connected to either end of the drive roller 201. A chain 203 is wound around the circumference of the gear 202. A transport motor 204 is fixedly connected to the gear 202 located on the outermost side. The transport motor 204 is fixedly mounted on the support frame 1 through a mounting bracket 205.

[0034] When in use, the transport motor 204 is turned on, which drives the gear 202 fixedly connected to its output shaft to rotate, thereby driving the other gears 202 to rotate through the chain 203, which in turn causes the drive roller 201 to rotate, thus transporting and conveying the glass body 7.

[0035] The working principle of this utility model is as follows: First, the transport motor 204 is turned on, which drives the gear 202 fixedly connected to its output shaft to rotate. This drives the other gears 202 to rotate through the chain 203, thereby causing the drive roller 201 to rotate and transport the glass body 7 into the tempering box 3 for heating and tempering.

[0036] Secondly, after the glass body 7 is heated and tempered, it enters the air grid box 4 for cooling. After cooling, when the glass body 7 with slag on its surface passes under the scraper plate 502, the scraper plate 502 sweeps off the slag on the glass body 7. The slag falls from between the active rollers 201 into the recycling box. During this process, the buffer spring 503 hardly generates any compression, or only generates slight compression.

[0037] Then, the congestion is identified and cleared. When the buffer spring 503 is compressed and the compression gradually increases, it indicates that there is glass congestion at the outlet of the air grille box 4, with glass fragments accumulating. This will push the translation plate 501 to move along the slide, thereby compressing the buffer spring 503. At this time, if... Figure 5 As shown, the rotary motor 604 is reversed, which drives the rotary arm 602 to rotate upward through the short shaft 603. This causes the passive roller 601 to rotate upward around the short shaft 603, thereby turning over the congested glass fragments. After the passive roller 601 is turned up, a larger gap is formed, and the glass fragments fall into the recycling box from the gap, thus completing the clearing of the glass blockage.

[0038] Finally, the intact glass body 7 is transported to the next process for processing via the transport component 2 below the air grille box 4.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
