[0002] Plastic is a synthetic polymer material with plasticity. Plastic products are a general term for products made from plastic as the main raw material. After plastic products are shaped, they need to be dried quickly to keep them in a suitable position. Conventional plastic products take a long time to dry naturally, so they need to be dried quickly using a drying device.

[0003] For example, according to patent announcement number CN220417951U, this invention discloses a plastic product drying device, including a drying chamber, a turntable, a heat-conducting cylinder, and an ultraviolet lamp. A first motor is installed at the center of the bottom of the drying chamber, and a turntable is installed at the output shaft end of the first motor. An annular groove is provided inside the top of the turntable, and locking blocks are evenly spaced inside the annular groove. The annular groove and the locking blocks are movably connected. A movable block is fixedly connected to one side of each locking block, and a spring is fixedly connected to one side of each movable block. This invention, by providing an annular groove at the top of the turntable and inserting the bottom of the heat-conducting cylinder into the annular groove, and by engaging the locking blocks on the annular groove with the locking slots on the heat-conducting cylinder, allows the heat-conducting cylinder to be fitted over the plastic product at the top of the turntable. The first motor drives the turntable to rotate, and in conjunction with the heating of the electric heating plate, the plastic product can be dried evenly while preventing overheating.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up an exhaust trough, an exhaust pipe, and a filter plate, utilizes the combination of the exhaust pipe and the filter plate to perform preliminary filtration of the exhaust gas containing VOCs and plastic dust generated during the drying process, intercepting solid particulate matter in the exhaust gas and reducing the content of pollutants directly emitted. Furthermore, the exhaust trough facilitates the installation of the filter plate by the user. This solves the problem that the drying device does not have an exhaust gas filtration structure, which would allow pollutants to be directly discharged into the atmosphere. Under sunlight, VOCs will undergo photochemical reactions with nitrogen oxides to form secondary pollutants such as ozone and PM2.5, exacerbating air pollution problems. This invention achieves the effect of exhaust gas filtration.

[0015] 2. This invention, by setting up an installation component and utilizing the sliding fit between the installation groove and the installation block, provides a convenient operation method for the installation, disassembly, and replacement of the filter plate. This effectively solves the problems of cumbersome disassembly and assembly and low maintenance efficiency in traditional exhaust gas filtration structures. When the filter plate becomes clogged or its filtration effect decreases due to long-term use, operators can directly pull the installation block out along the installation groove to quickly disassemble, clean, or replace the filter plate without the need for specialized tools, significantly shortening equipment downtime for maintenance. Simultaneously, the structural design of the fixed connection between the installation block and the filter plate ensures the stability of the filter plate within the exhaust pipe, preventing displacement or detachment of the filter plate due to exhaust gas flow impact. This ensures the continuity and reliability of the exhaust gas filtration process, improving both the ease of equipment maintenance and the effectiveness of exhaust gas filtration, thus achieving the effect of facilitating filter plate disassembly and assembly.

[0016] 3. This invention, through the inclusion of an auxiliary mechanism, utilizes a connecting groove, connecting block, and exhaust fan in conjunction with the exhaust fan. This achieves flexible assembly and disassembly of the exhaust fan, facilitating its maintenance and replacement. Furthermore, the forced exhaust effect of the exhaust fan significantly improves the device's exhaust gas emission efficiency and drying effect. During operation, the exhaust fan accelerates the flow of hot and exhaust gases within the chamber, allowing moisture and exhaust gases generated during drying to be quickly discharged through the exhaust pipe. This prevents humidity buildup within the chamber from affecting drying efficiency and ensures more even heat distribution, reducing uneven drying of plastic products due to localized high humidity. The electrical connection between the control panel and the exhaust fan allows operators to precisely adjust the fan speed according to the drying requirements of the plastic products, enabling controllable adjustment of the exhaust intensity. This adapts to the drying process requirements of different materials and shapes of plastic products, further enhancing the device's intelligence and adaptability, thus achieving the effect of auxiliary exhaust.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth. Example 1

[0023] Reference Figure 1-5This first embodiment of the invention provides a drying device for plastic product manufacturing, including a box body 1, a box door 2, a heating plate 3, an ultraviolet lamp holder 4, and a heat-conducting cylinder 5. The left side of the front of the box body 1 is movably connected to the left side of the box door 2 via a pivot pin. The outer side of the heating plate 3 is fixedly connected to both sides of the inner wall of the box body 1. The top of the ultraviolet lamp holder 4 is movably connected to the top of the inner wall of the box body 1. The bottom of the heat-conducting cylinder 5 is movably connected to the bottom of the inner wall of the box body 1. An air outlet groove 6 is provided on the rear side of the top of the box body 1, extending to the top of the inner wall of the box body 1. An air outlet pipe 7 is movably connected to the rear side of the top of the box body 1. The bottom surface of the air outlet pipe 7 is slidably connected to the inner wall of the air outlet groove 6. A filter plate 8 is slidably connected to the inner wall of the air outlet pipe 7. An installation assembly 9 is provided on the left side of the air outlet pipe 7. Auxiliary mechanisms 10 are provided on the bottom of both sides of the inner wall of the air outlet pipe 7.

[0024] Specifically, the use of the air outlet 6, air outlet pipe 7, and filter plate 8 together can prevent harmful particles generated during the drying of plastic from being released into the air.

[0025] Furthermore, by using the air outlet pipe 7 and the filter plate 8 together, the exhaust gas containing VOCs and plastic dust generated during the drying process can be initially filtered, intercepting solid particulate matter in the exhaust gas and reducing the content of pollutants directly emitted. The air outlet trough 6 can also be used to facilitate the installation of the filter plate 8 by the user. Example 2

[0026] In the second embodiment of the present invention, the mounting component 9 includes a mounting groove 91, which is opened on the left side of the air outlet pipe 7. A mounting block 92 is slidably connected to the inner wall of the mounting groove 91, and the right side of the mounting block 92 is fixedly connected to the left side of the filter plate 8.

[0027] Specifically, the installation component 9 allows users to quickly install and remove the filter plate 8.

[0028] Furthermore, the sliding fit between the mounting groove 91 and the mounting block 92 provides a convenient way to install, disassemble, and replace the filter plate 8, effectively solving the problems of cumbersome disassembly and assembly and low maintenance efficiency of traditional exhaust gas filtration structures. When the filter plate 8 becomes clogged and its filtration effect decreases due to long-term use, the operator can directly pull out the mounting block 92 along the mounting groove 91 to quickly disassemble, clean, or replace the filter plate 8 without the need for professional tools, greatly shortening the equipment downtime for maintenance. At the same time, the structural design of the fixed connection between the mounting block 92 and the filter plate 8 can ensure the installation stability of the filter plate 8 in the exhaust pipe 7, avoiding displacement or detachment of the filter plate 8 due to exhaust gas flow impact, ensuring the continuity and reliability of the exhaust gas filtration process, improving the convenience of equipment maintenance and ensuring the effect of exhaust gas filtration. Example 3

[0029] In the third embodiment of the present invention, the auxiliary mechanism 10 includes a connecting groove 101, which is opened at the bottom of both sides of the inner wall of the air outlet pipe 7. A connecting block 102 is slidably connected to the inner wall of the connecting groove 101, and an air outlet fan 103 is fixedly connected to the inner side of the connecting block 102. The surface of the air outlet fan 103 is slidably connected to the inner wall of the air outlet pipe 7. A control panel 104 is fixedly connected to the bottom of the front of the housing 1. The control panel 104 is electrically connected to the air outlet fan 103 through a wire.

[0030] Specifically, the auxiliary mechanism 10 can be used to accelerate the discharge speed of harmful particles inside the box 1.

[0031] Furthermore, by utilizing the connecting groove 101, connecting block 102, and exhaust fan 103 in conjunction, the exhaust fan 103 can be flexibly disassembled and assembled, facilitating its maintenance and replacement. Simultaneously, the forced exhaust effect of the exhaust fan 103 significantly improves the exhaust gas emission efficiency and drying effect of the device. When the exhaust fan 103 is working, it accelerates the flow rate of hot air and exhaust gas within the chamber 1, allowing the moisture and exhaust gas generated during drying to be quickly discharged through the exhaust pipe 7, preventing humidity accumulation within the chamber 1 from affecting drying efficiency. It also ensures more uniform heat distribution within the chamber 1, reducing uneven drying of plastic products due to excessively high local humidity. The electrical connection between the control panel 104 and the exhaust fan 103 allows operators to precisely adjust the speed of the exhaust fan 103 according to the drying requirements of the plastic products, achieving controllable adjustment of the exhaust intensity. This adapts to the drying process requirements of plastic products of different materials and shapes, further enhancing the intelligence and adaptability of the device. Working principle:

[0032] By integrating the housing 1, heating plate 3, ultraviolet lamp holder 4, heat conduction cylinder 5, and waste gas treatment-related structures, an integrated design of drying function and preliminary waste gas purification is achieved. This effectively solves the problems of low drying efficiency and direct emission of waste gas polluting the environment in traditional drying devices. The sliding fit between the mounting groove 91 and the mounting block 92 provides a convenient way to install, disassemble, and replace the filter plate 8, effectively solving the problems of cumbersome disassembly and assembly and low maintenance efficiency in traditional waste gas filtration structures. When the filter plate 8 becomes clogged due to long-term use and its filtration effect decreases, the operator can directly pull out the mounting block 92 along the mounting groove 91 to quickly disassemble, clean, or replace the filter plate 8 without the need for specialized equipment. The industrial tools significantly shorten the equipment downtime for maintenance. Meanwhile, the structural design of the fixed connection between the mounting block 92 and the filter plate 8 ensures the stability of the filter plate 8 within the exhaust pipe 7, preventing displacement or detachment of the filter plate 8 due to exhaust gas flow impact. This ensures the continuity and reliability of the exhaust gas filtration process, improving both the ease of equipment maintenance and the effectiveness of exhaust gas filtration. The connection groove 101, connecting block 102, and exhaust fan 103 work together to achieve flexible disassembly and assembly of the exhaust fan 103, facilitating its inspection and replacement. Furthermore, the forced exhaust effect of the exhaust fan 103 significantly improves the device's exhaust gas emission efficiency and drying effect.When the exhaust fan 103 is working, it can accelerate the flow speed of hot air and exhaust gas inside the chamber 1, allowing the moisture and exhaust gas generated during drying to be quickly discharged through the exhaust pipe 7. This prevents humidity accumulation inside the chamber 1 from affecting drying efficiency and also makes the heat distribution inside the chamber 1 more uniform, reducing uneven drying of plastic products due to excessively high local humidity. The electrical connection between the control panel 104 and the exhaust fan 103 allows operators to precisely adjust the speed of the exhaust fan 103 according to the drying requirements of the plastic products, achieving controllable adjustment of the exhaust intensity. This adapts to the drying process requirements of plastic products of different materials and shapes, further enhancing the intelligence and adaptability of the device. During the operation of the device, the drying... The resulting airflow impact and vibration of the exhaust fan 103 may cause the exhaust pipe 7 to shift. The reinforcing rod 13, screwed into the reinforcing groove 12 of the fixing block 11 and the housing 1, firmly secures the exhaust pipe 7 to the exhaust groove 6 at the top of the housing 1, preventing gaps between the exhaust pipe 7 and the housing 1 and preventing exhaust gas leakage that could pollute the workshop environment. Simultaneously, the threaded connection facilitates the overall disassembly of the exhaust pipe 7. When thorough cleaning or replacement of the exhaust pipe 7 is required, simply unscrew the reinforcing rod 13 to pull the exhaust pipe 7 out of the exhaust groove 6. This balances connection strength with ease of assembly and disassembly. When the user completely moves the connecting block 102 into the connecting groove 101... When the shielding strip 17 is fully moved into the shielding groove 16, it is inserted into the inner wall of the shielding groove 16. At this time, the shielding strip 17 will block the bottom of the surface of the connecting groove 101, preventing the connecting block 102 from moving downwards, thus making the exhaust fan 103 more stable. When the bottom of the surface of the exhaust pipe 7 is fully moved into the exhaust groove 6, the inner wall of the exhaust groove 6 can restrict the movement of the shielding strip 17, preventing the shielding strip 17 from detaching from the shielding groove 16, thereby avoiding the unstable installation of the exhaust fan 103. When the user needs to remove the shielding strip 17 from the shielding groove 16, the user moves their finger into the auxiliary groove 18 and uses the auxiliary strip 17 to remove the shielding strip 17. 9 increases the contact area between the user and the shielding strip 17, giving the user a larger point of force application. After the filter plate 8 is installed into the exhaust pipe 7 via the mounting block 92, the hook 21 is snapped into the connecting buckle 21, which can limit and fix the mounting block 92, preventing the mounting block 92 from sliding out along the mounting groove 91 when impacted by exhaust gas flow or when the equipment vibrates, ensuring the installation of the filter plate 8 in the exhaust pipe 7 is firm. At the same time, the snap-fit ​​method of the hook 21 and the connecting buckle 21 is easy to operate, and the operator can quickly complete the snap-fit ​​and unlocking without increasing the cumbersome disassembly and assembly of the filter plate 8. While improving the structural stability, it maintains the convenience of equipment maintenance, thereby achieving the effect of exhaust gas filtration.

[0033] In summary: by setting up the air outlet 6, the air outlet pipe 7, and the filter plate 8, the exhaust gas containing VOCs and plastic dust generated during the drying process can be initially filtered, intercepting solid particulate matter in the exhaust gas and reducing the content of pollutants directly emitted. Furthermore, the air outlet 6 makes it easy for users to install the filter plate 8, thus achieving the desired exhaust gas filtration effect.
