Description

Technical Field

[0001] The present invention relates to the technical field of baking equipment, and more specifically, it relates to a baking device for a plastic shell coating line of a fax machine and a method for using the same. Background Art

[0002] A fax machine is a communication device that uses scanning and optoelectronic conversion technologies to convert still images such as documents, charts, and photos into electrical signals, transmit them to the receiving end, and copy them in a recorded form. During the production of a fax machine, a plastic shell is usually used to protect the electronic components and circuits included in the fax machine. Therefore, during the production of a fax machine, it is usually necessary to carry out the production work of the plastic shell. However, during the production of the plastic shell, in order to ensure the aesthetics of the fax machine, it is usually necessary to spray paint and color the plastic shell of the fax machine. After the spraying and coloring are completed, a baking device for a plastic shell coating line of a fax machine is usually used to bake and dry the colored plastic shell.

[0003] According to the search of Baidu literature, the baking equipment of the plastic shell painting line for fax machines on the current market usually consists of a conveying device, a heating device, a baking chamber, a ventilation device, and a filtering device. Among these devices, the conveying device can move the sprayed plastic shell into the interior of the baking chamber, the heating device can bake the plastic shell entering the inner wall of the baking chamber, the ventilation device can ventilate the gas inside the baking chamber, and the filtering device can filter the impurities during the ventilation process. However, according to the search of Baidu literature, the entire painting production line is mainly divided into a pretreatment production line, a spraying production line, and a baking production line. In order to prevent external dust and other sundries from affecting the spraying, all three production lines are in a sealed state, and there is gas interconnection between the three production lines. Therefore, when the plastic shell in the spraying production line moves to the baking production line, some of the paint scattered during spraying may enter the baking production line. Therefore, during the filtering process of the filtering device on the gas transmitted by the ventilation device, paint may remain at the filtering device, which may then pose certain safety hazards. Moreover, after the filtering device has been used for a certain period of time, dust and other impurities will accumulate at the filtering device, which will in turn affect the filtering efficiency of the filtering device. Therefore, users usually need to clean the filtering device after it has been operating for a certain period of time. Because the filtering device is generally located inside the ventilation device, when users clean the filtering device, they often need to first disassemble some structures of the ventilation device, then take out the filtering device, and then clean the filtering device. However, when using this method, if the equipment is in an operating state, harmful gases and impurities will be discharged into the air, which will then cause damage to the staff and pollute the environment. If the equipment is in a shutdown state, a large amount of energy will be consumed for restarting work, which will in turn affect the energy saving of the equipment. Moreover, because the heating device directly increases the temperature inside the baking chamber, after the plastic shell enters the interior of the baking chamber, it will directly undergo high-temperature baking. However, there are still many flammable solvents and vapors attached to the plastic shell with wet paint. When the content of these vapors in the air reaches a certain concentration, encountering the fire source used for baking will cause the risk of explosion and fire, which will in turn affect the safety of the equipment.

[0015] The usage method of the baking equipment for the plastic shell of the above fax machine, the usage method includes the following steps:

[0016] Step 1: Through the operation of the first transfer pump, the air extraction pipe can extract air from the air collection plate, and then the second transfer pipe can extract air from the gas above the conveying device. Then, the gas is discharged into the internal of the air distribution plate through the exhaust pipe. Then, the burner is operated so that the burner can heat the first gas transmission pipe. Furthermore, the heat can be used to heat the air distribution plate. Then, the hot gas is discharged into the internal of the gas transmission cavity through the first gas transmission pipe. Finally, the hot gas passes through the filtration of the double-frame filter plate and is discharged above the conveying device, and then the internal of the sealing chamber can be heated;

[0017] Step 2: After the conveyor belt receives the plastic shell transmitted by the spraying line, the first drive motor can be operated so that the conveyor belt transports the plastic shell to the outside of the sealing chamber, and then the plastic shell can be baked through the heated sealing chamber;

[0018] Step 3: After Step 1 runs for a certain period of time, the second drive motor is operated so that the double-frame filter plate can move. Then, the plate body of the double-frame filter plate on one side of the gas transmission cavity can be moved to the first cleaning chamber or the second cleaning chamber. Furthermore, the plate body on the other side of the double-frame filter plate can be moved to the gas transmission cavity, so that a new plate body on the other side can filter the gas. Finally, the second transfer pump is operated so that the liquid extraction pipe can extract the liquid in the liquid storage tank, and then the liquid is transmitted into the internal of the liquid distribution plate through the liquid discharge pipe. Finally, the liquid is discharged through the first magnetic valve pipe and the nozzle, and then the part of the double-frame filter plate located in the first cleaning chamber or the second cleaning chamber can be cleaned;

[0019] Step 4: After Step 3 runs to completion, two third drive motors can be operated, and then the two sleeve rods can drive the two cleaning plates to move backward. Furthermore, the two cleaning plates can clean and push the impurities above the double-frame filter plate. The operation of the two third drive motors can also make the two first L-shaped plates drive the second sealing plate and the first sealing plate to move upward. The upward movement of the second sealing plate makes the filtration box communicate with the dust removal box, and then the impurities pushed by the cleaning plates can be discharged into the internal of the dust removal box. The upward movement of the first sealing plate will seal the dust discharge port of the dust removal box, thus preventing gas leakage during the dust discharge process of the equipment;

[0020] Step 5: After the operation in Step 4 ends, the two third driving motors can be run in reverse, so that the two sleeve rods can drive the two cleaning plates to move backward. At this time, due to the blockage of the movable plate, the two cleaning plates will not contact the double-frame filter plate, thus preventing the cleaning plates from pushing the newly generated impurities back to the position where they cannot be discharged. The two third driving motors running in reverse will also cause the two second sealing plates and the first sealing plate to move downward. The downward movement of the second sealing plate will make the filtering box and the dust removal box in a closed state, while the downward movement of the first sealing plate will make the dust discharge port of the dust removal box in an unfolded state, so that the dust removal box can carry out separate dust discharge work. Finally, the second magnetic valve pipe is opened, so that the liquid generated by cleaning is also discharged into the interior of the dust removal box, and then can be discharged from the interior of the filtering box together.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. For the baking equipment and its usage method of the plastic shell coating line of the fax machine, through the use of the air guiding component, when the first delivery pump is operating, the second delivery pipe can extract the gas around it, and then extract the dust and other impurities inside the sealed chamber. And due to the extraction of the second delivery pipe, the hot air on the side of the second delivery pipe away from the first driving motor will not move to the first driving motor, so that the temperature at the first driving motor will not change too much. Then, after the plastic shell after spraying enters the interior of the sealed chamber, it will be baked at normal temperature first and then at high temperature, thus reducing the potential safety hazards caused by direct high-temperature baking.

[0023] 2. For the baking equipment and its usage method of the plastic shell coating line of the fax machine, through the use of the second driving motor, the first gear can rotate, so that the double-frame filter plate can move left and right, and then both plates of the double-frame filter plate can move into the air transmission cavity. Then, after one plate of the double-frame filter plate filters for a period of time, the other plate can filter the transmitted gas, thus ensuring the gas filtration efficiency. The combined use of the liquid delivery component, the spray head, the liquid distribution plate and the first magnetic valve pipe can clean some of the double-frame filter plates located at the first cleaning chamber or the second cleaning chamber. Then, after the other plate operates for a period of time, the cleaned plate can continue to filter, thereby further improving the filtration efficiency of the double-frame filter plate. And the use of this cleaning method completely eliminates the time and labor consumed by shutdown cleaning, thus improving the overall working efficiency of the equipment.

[0024] 3. The baking equipment of the plastic shell coating line of the fax machine and its usage method. Through the coordinated use of the third driving motor, the second gear, the sleeve rod, and the first L-shaped plate, the cleaning plate can be moved back and forth, and the second sealing plate and the first sealing plate can be moved up and down. Thus, after the impurities in the internal gaps of the double-frame filter plate are cleaned by the nozzle, the impurities accumulated above the double-frame filter plate can be hermetically discharged. Furthermore, the overall cleaning quality of the equipment can be ensured, and the working efficiency of the equipment can be further guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

A suction pipe 21 is fixedly connected to the bottom of the first conveying pump 20. The bottom of the suction pipe 21 penetrates through the gas collecting plate 19 and extends to its inside. An exhaust pipe 22 is fixedly connected to the top of the first conveying pump 20. One end of the exhaust pipe 22 penetrates through the sealing chamber 2 and the gas transmission box 10 and extends to the inside of the gas distribution plate 12. A second conveying pipe 23 is fixedly connected to the bottom of the gas collecting plate 19. The bottom of the second conveying pipe 23 penetrates through the sealing chamber 2 and extends to the outside thereof;

[0043] In this embodiment, the operation of the first conveying pump 20 can enable the second conveying pipe 23 to extract the gas and impurities inside the sealing chamber 2, and then it can be discharged into the inside of the gas distribution plate 12 through the exhaust pipe 22. Then, in cooperation with the operation of the burner 11, the gas inside the gas distribution plate 12 can be heated. In cooperation with the use of the first gas transmission pipe 13, the heated gas can be discharged into the inside of the filtering component 9. Furthermore, through the gas transmission of the filtering component 9, the hot gas can be led into the inside of the sealing chamber 2, so that the inside of the sealing chamber 2 can be heated. Then, after the plastic shell enters the inside of the sealing chamber 2, the plastic shell can be baked;

[0044] Such as Figure 4 、 Figure 5 、 Figure 7 、 Figure 12 、 Figure 13 and Figure 14As shown, the driving assembly 6 includes a second driving motor 37. The surface of the output rod of the second driving motor 37 is fixedly connected with a first gear 38. The surface of the first gear 38 meshes with the bottom of the rack 31. The infusion assembly 8 includes a liquid storage tank 24. The top of the liquid storage tank 24 is fixedly connected with a second delivery pump 25. The bottom of the second delivery pump 25 is fixedly connected with a liquid suction pipe 26. The bottom of the liquid suction pipe 26 penetrates through the liquid storage tank 24 and extends to its interior. The top of the second delivery pump 25 is fixedly connected with a liquid discharge pipe 27. One end of the liquid discharge pipe 27 penetrates through the liquid distribution plate 32 and extends to its interior. The filtering assembly 9 includes a filtering box 28. The interior of the filtering box 28 is provided with a first cleaning chamber, a gas transmission chamber and a second cleaning chamber. The tops of the first cleaning chamber and the second cleaning chamber are both fixedly connected with spray heads 29. A double-frame filter plate 30 is installed inside the filtering box 28. Both sides of the double-frame filter plate 30 are fixedly connected with racks 31. The top of the filtering box 28 is fixedly connected with a liquid distribution plate 32. Both sides of the bottom of the liquid distribution plate 32 are fixedly connected with first solenoid valve pipes 33. One end of the first solenoid valve pipe 33 is connected with the spray head 29. Shifting plate grooves are opened on both sides of the first cleaning chamber, the gas transmission chamber and the second cleaning chamber. Adjusting channels are opened at the bottoms of the shifting plate grooves. A torsion spring rod 34 is rotatably installed inside the adjusting channels. The surface of the torsion spring rod 34 is fixedly connected with a movable plate 35. Second solenoid valve pipes 36 are fixedly connected to one side of the first cleaning chamber and the second cleaning chamber close to the dust guiding assembly 4. Moving grooves are opened on both sides of the first cleaning chamber, the gas transmission chamber and the second cleaning chamber close to the rack 31. The rack 31 is located inside the moving grooves;

[0045] In this embodiment, the operation of the second driving motor 37 enables the first gear 38 to rotate, and further enables the double-frame filter plate 30 to move left and right. As a result, both plates of the double-frame filter plate 30 can move into the gas transmission chamber. Thus, after one plate of the double-frame filter plate 30 filters for a period of time, the other plate can perform the filtering work, ensuring the gas filtering efficiency. The operation of the second delivery pump 25 enables the liquid inside the liquid storage tank 24 to be transported into the liquid distribution plate 32. Then, in cooperation with the activation of the first solenoid valve pipe 33 and the spray head 29, automatic water washing of a part of the double-frame filter plate 30 located at the first cleaning chamber or the second cleaning chamber can be carried out. Finally, through the opening and closing of the second solenoid valve pipe 36, the impurities generated by the water washing can be discharged into the dust guiding assembly 4;

[0046] Such as Figure 3 、 Figure 6 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 14 and Figure 15As shown in the figure, the dust guiding component 4 includes a dust removal box 39. A connecting frame 40 is fixedly connected to one side of the dust removal box 39 away from the sealing chamber 2. A telescopic rod 41 is fixedly connected to the top of the connecting frame 40. A first sealing plate 42 is fixedly connected to the bottom of the telescopic rod 41. A limiting groove is formed in the side wall of the bottom plate of the connecting frame 40. Both sides of the first sealing plate 42 are located inside the limiting groove. The dust discharging component 5 includes a first U-shaped frame 43. A fixing plate 52 is fixedly connected to the top of the first U-shaped frame 43. A second limiting rod 53 is fixedly connected to the inside of the fixing plate 52. A third moving block 54 is slidably connected to the surface of the second limiting rod 53. A first L-shaped plate 55 is fixedly connected to the side of the third moving block 54 close to the sealing chamber 2. A supporting plate 56 is fixedly connected to the bottom of the first L-shaped plate 55. A second sealing plate 57 is fixedly connected to the bottom of the supporting plate 56. A second L-shaped plate 58 is fixedly connected to the side of the supporting plate 56 close to the dust guiding component 4. The side of the second L-shaped plate 58 close to the dust guiding component 4 is connected to the first sealing plate 42. An internal tooth groove is formed in the first L-shaped plate 55. One side of the internal tooth groove is meshed with the surface of a second gear 46. A partition plate 44 is fixedly connected to the center of the first U-shaped frame 43. A third driving motor 45 is fixedly connected to the side of the first U-shaped frame 43 away from the sealing chamber 2. A second gear 46 is fixedly connected to the surface of the output rod of the third driving motor 45. A sleeve rod 47 is slidably sleeved on the surface of the output rod of the third driving motor 45. An activity groove is formed in the side of the sleeve rod 47 away from the second gear 46. A first limiting rod 48 is fixedly connected to the bottom of the activity groove. A first moving block 49 is slidably connected to the surface of the first limiting rod 48. A cleaning plate 50 is fixedly connected to the side of the first moving block 49 away from the sleeve rod 47. Second moving blocks 51 are fixedly connected to both sides of the cleaning plate 50. The second moving blocks 51 are located inside the moving plate grooves;

[0047] In this embodiment, the limiting groove formed in the connecting frame 40 can limit the movement of the first sealing plate 42. The operation of the third driving motor 45 can not only cause the second gear 46 to rotate, but also cause the sleeve rod 47 to move back and forth. The rotation of the second gear 46 can cause the first L-shaped plate 55 to move up and down. The up and down movement of the first L-shaped plate 55 will cause the support plate 56 and the second L-shaped plate 58 to move up and down, thereby driving the second sealing plate 57 and the first sealing plate 42 to move up and down. When both the second sealing plate 57 and the first sealing plate 42 move upward, the filter box 28 and the dust removal box 39 can be in a communicating state, and the dust discharge port of the dust removal box 39 can be in a sealed state. When the second sealing plate 57 and the first sealing plate 42 move downward, the filter box 28 and the dust removal box 39 can be in a sealed state, and the dust discharge port of the dust removal box 39 can be in an externally communicating state. The back and forth movement of the sleeve rod 47 will drive the cleaning plate 50 to move back and forth. When the cleaning plate 50 moves backward, the cleaning plate 50 can push the impurities above the double-frame filter plate 30 backward. Because the filter box 28 and the dust removal box 39 are in a communicating state, the cleaning plate 50 can discharge the impurities above the double-frame filter plate 30 into the interior of the dust removal box 39. Among them, the second moving block 51 connected to the cleaning plate 50 will generate a backward force on the movable plate 35 during the backward movement of the cleaning plate 50, thereby causing the movable plate 35 to rotate backward. Because the torsion spring rod 34 has a torsion spring, when the second moving block 51 no longer contacts the movable plate 35, the movable plate 35 will reset. When the cleaning plate 50 moves forward, because the movable plate 35 contacts the inclined channel, the movable plate 35 will not move forward. Therefore, after the second moving block 51 contacts the movable plate 35, the second moving block 51 will generate an upward moving force on the cleaning plate 50. Then, with the help of the first limiting rod 48 and the first moving block 49, the cleaning plate 50 can move to the upper channel. Then, after moving to the initial position, due to the action of gravity, the cleaning plate 50 will reset and move. During this period, because the cleaning plate 50 is in the upper position, the cleaning plate 50 will not work on the newly generated impurities above the double-frame filter plate 30, thereby ensuring that the subsequent cleaning of the cleaning plate 50 will not be affected;

[0048] As Figure 8 shown, the conveying device 1 includes a conveying frame 14. One side of the conveying frame 14 is fixedly connected with a first driving motor 15. The surface of the output rod of the first driving motor 15 is connected with a conveyor belt 16. The other side of the conveying frame 14 away from the first driving motor 15 is rotatably connected with a passive rod 17. The surface of the passive rod 17 is connected with one side of the conveyor belt 16. The center of the conveying frame 14 is rotatably connected with a support rod 18. The top and bottom of the support rod 18 are both in contact with the conveyor belt 16;

[0049] In this embodiment, the operation of the first driving motor 15 enables the conveyor belt 16 to convey the plastic housing above it, so that the heat inside the sealing chamber 2 can bake the plastic housing. During this period, the support rod 18 can support the middle position of the conveyor belt 16, thereby preventing the height of the plastic housing from shifting;

[0050] The usage method of the baking equipment for the plastic outer shell of the above fax machine includes the following steps:

[0051] Step 1: Through the operation of the first delivery pump 20, the air extraction pipe 21 can extract air from the air collection plate 19, then the second delivery pipe 23 can extract air from the gas above the conveying device 1, and then the gas is discharged into the air distribution plate 12 through the exhaust pipe 22. Then, the burner 11 is operated so that the burner 11 can heat the first gas delivery pipe 13, and then the air distribution plate 12 can be heated by this heat. Then, the hot air is discharged into the air transmission cavity through the first gas delivery pipe 13. Preferably, the hot air is filtered by the double-frame filter plate 30 and then discharged above the conveying device 1, and then the inside of the sealing chamber 2 can be heated;

[0052] Step 2: After the conveyor belt 16 receives the plastic housing transmitted from the spraying line, the first driving motor 15 can be operated to make the conveyor belt 16 convey the plastic housing to the outside of the sealing chamber 2, and then the plastic housing can be baked by the heated sealing chamber 2;

[0053] Step 3: After Step 1 runs for a certain period of time, the second driving motor 37 is operated so that the double-frame filter plate 30 can move, and then the plate body of the double-frame filter plate 30 on one side of the air transmission cavity can be moved to the first cleaning cavity or the second cleaning cavity, and then the plate body on the other side of the double-frame filter plate 30 can be moved to the air transmission cavity, so that the brand-new plate body on the other side can filter the gas. Finally, the second delivery pump 25 is operated so that the liquid extraction pipe 26 can extract the liquid inside the liquid storage tank 24, and then the liquid is transmitted into the liquid distribution plate 32 through the liquid discharge pipe 27, and finally the liquid is discharged through the first magnetic valve pipe 33 and the spray head 29, and then the part of the double-frame filter plate 30 located at the first cleaning cavity or the second cleaning cavity can be cleaned;

[0054] Step 4: After the operation in Step 3 is completed, two third driving motors 45 can be operated, so that the two sleeve rods 47 can drive the two cleaning plates 50 to move backward, so that the two cleaning plates 50 can clean and push the impurities above the double-frame filter plate 30. The operation of the two third driving motors 45 can also make the two first L-shaped plates 55 drive the second sealing plate 57 and the first sealing plate 42 to move upward. The upward movement of the second sealing plate 57 makes the filter box 28 communicate with the dust removal box 39, so that the impurities pushed by the cleaning plate 50 can be discharged into the interior of the dust removal box 39. The upward movement of the first sealing plate 42 seals the dust discharge port of the dust removal box 39, thus preventing gas leakage during the dust discharge process of the equipment.

[0055] Step 5: After the operation in Step 4 is completed, the two third driving motors 45 can be operated in reverse, so that the two sleeve rods 47 can drive the two cleaning plates 50 to move backward. At this time, due to the block of the movable plate 35, the two cleaning plates 50 will not contact the double-frame filter plate 30, thus preventing the cleaning plates 50 from pushing the newly generated impurities back to the position where they cannot be discharged. The two third driving motors 45 operated in reverse will also make the two second sealing plates 57 and the first sealing plate 42 move downward. The downward movement of the second sealing plate 57 makes the filter box 28 and the dust removal box 39 in a closed state. The downward movement of the first sealing plate 42 makes the dust discharge port of the dust removal box 39 in an open state, so that the dust removal box 39 can perform independent dust discharge work. Finally, the second magnetic valve tube 36 is opened, so that the liquid generated by cleaning is also discharged into the interior of the dust removal box 39, and then can be discharged from the interior of the filter box 28 together.

The above specific implementation manners are only illustrative and not restrictive. Under the inspiration of this example, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this example.

7. The usage method of a baking device for a fax machine plastic shell coating line according to claim 6, characterized in that The usage method includes the following steps: Step 1: By operating the first transfer pump (20), the air suction pipe (21) can perform air suction work on the air collecting plate (19), and then the second transfer pipe (23) can perform air suction work on the gas above the conveying device (1). Then, the gas is discharged into the internal of the air distribution plate (12) through the exhaust pipe (22). Then, operate the burner (11) so that the burner (11) can heat the first gas transmission pipe (13). Furthermore, the heat can be used to heat the air distribution plate (12). Then, the hot gas is discharged into the internal of the gas transmission cavity through the first gas transmission pipe (13). The hot gas is filtered by the double-frame filter plate (30) and then discharged above the conveying device (1), and then the inside of the sealing chamber (2) can be heated. Step 2: After the conveyor belt (16) receives the plastic outer shell transmitted by the spraying line, operate the first driving motor (15) so that the conveyor belt (16) conveys the plastic outer shell to the outside of the sealing chamber (2), and then the plastic outer shell can be baked through the heated sealing chamber (2). Step 3: After running for a certain period of time in Step 1, run the second driving motor (37) so that the double-frame filter plate (30) can move. Subsequently, the plate body of the double-frame filter plate (30) on one side of the air transmission cavity can be moved to the first cleaning cavity or the second cleaning cavity, and then the plate body on the other side of the double-frame filter plate (30) can be moved to the air transmission cavity. Thus, the brand-new plate body on the other side can filter the gas. Finally, run the second delivery pump (25) so that the liquid extraction pipe (26) can extract the liquid inside the liquid storage tank (24), and then transmit the liquid to the inside of the liquid distribution plate (32) through the liquid discharge pipe (27). Finally, discharge the liquid through the first magnetic valve pipe (33) and the nozzle (29), and then the part of the double-frame filter plate (30) located at the first cleaning cavity or the second cleaning cavity can be cleaned; Step 4: After the operation in Step 3 is completed, run two third driving motors (45). Subsequently, the two sleeve rods (47) can drive the two cleaning plates (50) to move backward. Thus, the two cleaning plates (50) can clean and push the impurities above the double-frame filter plate (30). Moreover, the operation of the two third driving motors (45) can also drive the two first L-shaped plates (55) to move upward with the second sealing plate (57) and the first sealing plate (42). The upward movement of the second sealing plate (57) makes the filter box (28) communicate with the dust removal box (39). Subsequently, the impurities pushed by the cleaning plates (50) can be discharged into the dust removal box (39). The upward movement of the first sealing plate (42) seals the dust discharge port of the dust removal box (39), thus preventing gas leakage during the dust discharge process of the equipment; Step 5: After the operation in Step 4 is completed, run the two third driving motors (45) in reverse. Subsequently, the two sleeve rods (47) can drive the two cleaning plates (50) to move backward. At this time, due to the blockage of the movable plate (35), the two cleaning plates (50) will not contact the double-frame filter plate (30), thus preventing the cleaning plates (50) from pushing the newly generated impurities back to the position where they cannot be discharged. The reverse operation of the two third driving motors (45) can also drive the two second sealing plates (57) and the first sealing plate (42) to move downward. The downward movement of the second sealing plate (57) makes the filter box (28) and the dust removal box (39) in a closed state. The downward movement of the first sealing plate (42) makes the dust discharge port of the dust removal box (39) in an open state. Thus, the dust removal box (39) can perform separate dust discharge work. Finally, open the second magnetic valve pipe (36) so that the liquid generated by cleaning is also discharged into the dust removal box (39), and then it can be discharged from the inside of the filter box (28) together.
