Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, specifically to a drying oven for processing plastic products. Background Technology

[0002] Plastic is a material mainly composed of synthetic or natural polymer compounds that can be molded under certain conditions (such as temperature and pressure) and can maintain its shape at room temperature. When plastic is produced into plastic products, a drying oven is needed to dry the paint sprayed on its surface. However, existing drying ovens have some shortcomings in use. In order to meet the needs of the market, a drying oven for processing plastic products is needed.

[0003] Existing drying ovens suffer from insufficient drying efficiency. Furthermore, the inconvenience of cleaning and replacing the filter screens prevents the oven from filtering dust and impurities from the air entering the oven, hindering user cleaning and replacement. Additionally, the overall sealing of existing ovens is inadequate, allowing hot air to escape through gaps between the oven body and the sealing door, resulting in energy waste and reduced overall airtightness. Moreover, the drying process is uneven, preventing the even distribution of hot air within the oven and reducing the drying efficiency of the paint on the workpiece surface. Utility Model Content

A removable baffle is provided on the surface of the filter box. Temperature sensors are installed inside both the furnace body and the heating box. An exhaust pipe assembly is installed on the surface of the furnace body. The bottom end of the exhaust pipe assembly extends into the interior of the furnace body.

[0007] Preferably, the cleaning and replacement mechanism consists of guide blocks, anti-loosening sleeves, mounting studs, sliders, and support plates. Guide blocks are symmetrically installed on both sides of the filter screen, and the guide blocks slide against the inner wall of the U-shaped seat. Two sets of sliders are symmetrically installed at the bottom of the filter screen, and a support plate is installed on the surface of the U-shaped seat, with the support plate sliding against the surface of the sliders.

[0008] Preferably, the surface of the U-shaped seat is fitted with an anti-loosening screw sleeve, and the surface of the anti-loosening screw sleeve is threadedly connected with a mounting stud.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the drying oven for processing plastic products not only filters dust and impurities in the air entering the oven body during use, but also facilitates the user's cleaning and replacement of the filter screen. It prevents hot air from flowing out through the gap between the oven body and the sealing door, thus avoiding energy waste. It also improves the overall sealing of the drying oven and allows the hot air to be evenly diffused into the interior of the oven body, resulting in higher drying efficiency of the paint on the surface of the workpiece.

[0014] 1. With a cleaning and replacement mechanism, the filter screen moves along the guide block on the inner wall of the U-shaped seat. When the filter screen moves, it moves the slider on the surface of the support plate. Under the combined action of the guide block and the slider, the filter screen is guided. The user tightens the mounting studs, which then install the filter screen on the surface of the U-shaped seat. The anti-loosening sleeve and the mounting studs work together to prevent the mounting studs from accidentally coming loose, making the filter screen more stable when installed on the U-shaped seat. This enables the drying oven to clean and replace the filter screen, allowing it to filter dust and impurities from the air entering the oven. It also makes it convenient for the user to clean and replace the filter screen.

[0015] 2. By incorporating a high-sealing mechanism, the sealing gasket on the inner wall of the sealing door moves into the sealing groove. The sealing groove and the sealing gasket work together to seal the furnace body and the sealing door. The rubber gasket on the inner wall of the sealing door moves to contact the surface of the silicone gasket on the inner wall of the furnace body. The combined action of the rubber and silicone gaskets seals the furnace body and the sealing door, resulting in a higher sealing performance between them. Simultaneously, it improves the internal insulation of the furnace body, achieving a high-sealing function for the drying oven. This prevents hot air from leaking out through the gaps between the furnace body and the sealing door, thus avoiding energy waste and enhancing the overall sealing performance of the drying oven.

[0016] 3. By setting up a uniform drying mechanism, the controller controls the opening of the second valve on the surface of the tube body. The hot air inside the heating box enters the interior of the drying plate through the tube body, and then is evenly sprayed onto the surface of the workpiece body inside the furnace body through the air outlet. This makes the hot air more evenly distributed inside the furnace body, resulting in higher drying efficiency for the paint on the surface of the workpiece body. This achieves the function of uniform drying in the drying oven, allowing the hot air to be evenly diffused into the interior of the furnace body during use, thus making the drying efficiency of the paint on the surface of the workpiece body higher.

[0025] Furthermore, such as Figure 2 and Figure 4As shown, a cleaning and replacement mechanism 2 is provided on the surfaces of the U-shaped seat 119 and the filter screen plate 120. The cleaning and replacement mechanism 2 consists of a guide block 21, an anti-detachment sleeve 22, a mounting stud 23, a slider 24, and a support plate 25. Guide blocks 21 are symmetrically installed on both sides of the filter screen plate 120. The guide blocks 21 slide against the inner wall of the U-shaped seat 119. Two sets of sliders 24 are symmetrically installed at the bottom of the filter screen plate 120. A support plate 25 is installed on the surface of the U-shaped seat 119.

The anti-detachment sleeve 22 and the mounting stud 23 cooperate with each other.

[0026] During implementation, the filter screen 120 drives the guide block 21 to slide on the inner wall of the U-shaped seat 119. When the filter screen 120 moves, it drives the slider 24 to slide on the surface of the support plate 25. Under the combined action of the guide block 21 and the slider 24, the filter screen 120 is guided. The user tightens the mounting stud 23, and the filter screen 120 is installed on the surface of the U-shaped seat 119 under the action of the mounting stud 23. With the cooperation of the anti-loosening sleeve 22 and the mounting stud 23, the phenomenon of accidental loosening of the mounting stud 23 can be avoided, making the filter screen 120 more stable when installed on the surface of the U-shaped seat 119, so as to realize the function of cleaning and replacing the filter screen 120 by the drying oven.

[0027] Furthermore, such as Figure 2 and Figure 5 As shown, the inner walls of the furnace body 1 and the sealing door 12 are provided with a high-sealing mechanism 3. The high-sealing mechanism 3 includes a rubber gasket 31, a silicone gasket 32, a sealing groove 33, and a sealing pad 34. The sealing pad 34 is installed on the inner wall of the sealing door 12. The sealing groove 33 is opened on the surface of the furnace body 1. One end of the sealing pad 34 extends into the interior of the sealing groove 33 and contacts the inner wall of the sealing groove 33. The silicone gasket 32 ​​is installed on the inner wall of the furnace body 1, and the rubber gasket 31 is installed on the inner wall of the sealing door 12. The surfaces of the rubber gasket 31 and the silicone gasket 32 ​​are in close contact.

[0028] During implementation, the sealing gasket 34 on the inner wall of the sealing door 12 moves into the interior of the sealing groove 33. With the combined action of the sealing groove 33 and the sealing gasket 34, a seal is formed between the furnace body 1 and the sealing door 12. The rubber gasket 31 on the inner wall of the sealing door 12 moves to fit against the surface of the silicone gasket 32 ​​on the inner wall of the furnace body 1. With the combined action of the rubber gasket 31 and the silicone gasket 32, a seal is formed between the furnace body 1 and the sealing door 12, resulting in higher sealing performance between the furnace body 1 and the sealing door 12. At the same time, it can improve the heat preservation effect inside the furnace body 1, so as to achieve the high sealing performance of the drying oven.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, a uniform drying mechanism 4 is provided inside the furnace body 1 and on the surface of the heating box 113. The uniform drying mechanism 4 consists of a second valve 41, a pipe 42, an air outlet 43, and a drying plate 44. The pipe 42 is installed on the surface of the heating box 113, and the bottom end of the pipe 42 extends into the interior of the furnace body 1. The second valve 41 is fitted on the surface of the pipe 42. The second valve 41 can be of the TM series. The input end of the second valve 41 is electrically connected to the output end of the controller 11. The drying plate 44 is installed inside the furnace body 1 and is connected to the pipe 42. Multiple sets of air outlets 43 are arrayed on the surface of the drying plate 44.

[0030] During implementation, when the temperature inside the heating chamber 113 reaches the set value, the controller 11 controls the second valve 41 on the surface of the tube 42 to open. The hot air inside the heating chamber 113 enters the interior of the drying plate 44 through the tube 42, and then is evenly sprayed onto the surface of the workpiece body 16 inside the furnace body 1 through the air outlet 43. This makes the hot air more evenly distributed inside the furnace body 1, and the drying efficiency of the paint on the surface of the workpiece body 16 is higher, so as to achieve the function of uniform drying of the drying oven.

[0031] Working Principle: In use, first place the furnace body 1 in the designated position. The bottom of the furnace body 1 is supported by the support frame 14. The user opens the sealing door 12 and starts the controller 11, causing the controller 11 to control the conveying assembly 15 inside the conveying track 13. Under the action of the conveying assembly 15, the conveyor frame 152 and the painted workpiece body 16 to be dried are conveyed into the interior of the furnace body 1. After reaching the designated position, the controller 11 controls the conveying assembly 15 to close, and the user closes the sealing door 12 to seal the interior of the furnace body 1. The controller 11 then controls the air pump 19 to operate, drawing external air through the air inlet pipe 110 into the filter box 111. Dust and impurities in the air are filtered by the filter screen 120. Subsequently, the filtered air enters the heating box 113 through the through-hole. The controller 11 controls the heating plate 112 to operate, and the heating plate 112 heats the workpiece. The air inside the heating chamber 113 is heated after treatment. The temperature inside the heating chamber 113 is monitored in real time by the temperature sensor 17. When the air inside the heating chamber 113 is heated to the set temperature value, the controller 11 controls the first valve 116 to work. The hot air inside the heating chamber 113 enters the air guide pipe 18 through the air outlet pipe 114, and is then sprayed onto the surface of the workpiece body 16 inside the furnace body 1 through the air outlet nozzle 115 to dry the paint sprayed on the surface of the workpiece body 16. The temperature inside the furnace body 1 is monitored in real time by the temperature sensor 17. Since the material of the furnace body 1 adopts a heat-insulating structure, it can play a good heat-insulating role. When the conveying component 15 conveys the workpiece body 16 into the furnace body 1, the controller 11 controls the rotating component 118 inside the support platform 151 to start, driving the conveyor frame 152 and the workpiece body 16 to rotate inside the furnace body 1, so that the drying efficiency of the surface of the workpiece body 16 is higher.

[0032] Subsequently, after prolonged use, the filter screen 120 inside the filter box 111 is prone to clogging, requiring regular cleaning or replacement. The user opens the door on the surface of the filter box 111 and pulls the filter screen 120 inside, causing it to slide along the guide block 21 on the inner wall of the U-shaped seat 119. As the filter screen 120 moves, it drives the slider 24 to slide on the surface of the support plate 25. The combined action of the guide block 21 and the slider 24 guides the filter screen 120. Tighten the mounting stud 23. Under the action of the mounting stud 23, the filter screen 120 is installed on the surface of the U-shaped seat 119. With the cooperation of the anti-loosening sleeve 22 and the mounting stud 23, the installation stud 23 can be prevented from accidentally loosening. This makes the filter screen 120 more stable when installed on the surface of the U-shaped seat 119, so as to realize the function of cleaning and replacing the filter screen 120 in the drying oven. This allows the drying oven to filter dust and impurities in the air entering the oven body 1 during use. At the same time, it makes it convenient for users to clean and replace the surface of the filter screen 120.

[0033] Subsequently, when the sealing door 12 is closed, the sealing gasket 34 on the inner wall of the sealing door 12 moves into the interior of the sealing groove 33. With the joint cooperation of the sealing groove 33 and the sealing gasket 34, the furnace body 1 and the sealing door 12 are sealed. The rubber gasket 31 on the inner wall of the sealing door 12 moves to fit against the surface of the silicone gasket 32 ​​on the inner wall of the furnace body 1. With the joint action of the rubber gasket 31 and the silicone gasket 32, the furnace body 1 and the sealing door 12 are sealed, resulting in higher sealing performance between the furnace body 1 and the sealing door 12. At the same time, it can improve the heat preservation effect inside the furnace body 1, so as to achieve the high sealing function of the drying oven. This prevents hot air from flowing out through the gap between the furnace body 1 and the sealing door 12 during the use of the drying oven, thus avoiding energy waste and making the overall sealing performance of the drying oven higher.

[0034] Subsequently, when the temperature inside the heating chamber 113 reaches the set value, the controller 11 controls the second valve 41 on the surface of the tube 42 to open. The hot air inside the heating chamber 113 enters the interior of the drying plate 44 through the tube 42, and then is evenly sprayed onto the surface of the workpiece body 16 inside the furnace body 1 through the air outlet 43. This makes the hot air more evenly distributed inside the furnace body 1, resulting in higher drying efficiency for the paint on the surface of the workpiece body 16. This achieves the function of uniform drying in the drying oven, allowing the hot air to be evenly diffused into the interior of the furnace body 1 during use, thus making the drying oven more efficient at drying the paint on the surface of the workpiece body 16, and finally completing the use of the drying oven.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
