Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 Please see Figures 1 to 4 A toothed strip drying device includes a toothed strip drying rack 1, a draining tray 2 for pre-treating and draining the toothed strips on the toothed strip drying rack 1, a drying chamber 3 for drying the toothed strips on the toothed strip drying rack 1, and a roller shutter door 31 installed on the drying chamber 3. The inner wall of the drying chamber 3 is also provided with a flame-retardant heat-insulating cotton sandwich panel 35. When drying the toothed strips in the drying chamber 3, the roller shutter door 31 is closed to provide heat insulation. The drying chamber 3 is provided with a heating and drying mechanism 4, which is used to provide heating airflow inside the drying chamber 3. The drying chamber body 3 is provided with a conveying track 32, which is used to input the toothed strip drying rack 1 containing toothed strips into the drying chamber body 3; at the same time, in this application, the drying chamber body 3 is also provided with a winch unit, which provides power for the toothed strip drying rack 1 to move on the conveying track 32. The heating and drying mechanism 4 includes a natural gas pipeline 41, a natural gas heating main nozzle 42, a natural gas heating auxiliary nozzle, and a temperature control fan 44, all of which are installed on the drying chamber body 3. The temperature control fan 44 is used to control the internal temperature of the drying chamber body 3. The natural gas heating main nozzle 42 is ignited when all the drying teeth are delivered into the drying chamber body 3, and plays the main heating role. Meanwhile, a natural gas pipeline pressure controller is also installed on the natural gas pipeline 41, which controls the pressure of the natural gas pipeline 41 that supplies the natural gas to the main natural gas heating nozzle 42 and the auxiliary natural gas heating nozzle 43.

[0019] The natural gas heating auxiliary nozzle 43 and the natural gas heating main nozzle 42 heat to the specified temperature. After the fire is stopped, the natural gas heating auxiliary nozzle 43 is ignited to provide auxiliary heat preservation and heating. Temperature control fan 44 and natural gas pipeline 41 are used to supply gas to natural gas heating main nozzle 42 and natural gas heating auxiliary nozzle 43. When natural gas heating main nozzle 42 and natural gas heating auxiliary nozzle 43 are ignited, temperature control fan 44 is turned on to control the temperature inside drying chamber 3, so that the drying chamber 3 is heated evenly. The drying chamber body 3 is equipped with a temperature control probe 33 and a temperature control system 34. The temperature control probe 33 is electrically connected to the temperature control system 34. The temperature control probe 33 monitors the temperature inside the drying chamber body 3 and transmits the temperature data to the temperature control system 34. The temperature control system 34 is the existing temperature control system 34. Based on the temperature inside the drying chamber 3 transmitted by the temperature control probe 33, it controls whether the main natural gas heating nozzle 42 and the auxiliary natural gas heating nozzle 43 are ignited, as well as the natural gas pressure of the nozzle of the pressure controller of the natural gas pipeline 41. Specific implementation process: The toothed bar drying rack 1 is placed on the draining tray 2. The toothed bars to be dried are neatly arranged on the toothed bar drying rack 1 by a crane. The hoist unit uses a wire rope hook to drag the toothed bar drying rack 1 with the toothed bars to be dried into the drying chamber 3. After a certain number of toothed bars to be dried are placed, the roller shutter door 31 is closed. After the process temperature is set, the temperature control system 34 is started to ignite and heat up. The natural gas heating main nozzle 42 is ignited and heated up. After the temperature reaches the specified temperature, the temperature control system 34 controls the natural gas heating. The main nozzle 42 is shut down, and the start and stop of the natural gas heating auxiliary nozzle 43 is controlled for auxiliary heat preservation. Once the heat preservation process time is up, the temperature control system 34 controls the natural gas heating auxiliary nozzle 43 to shut down. After a period of time, the temperature of the drying chamber 3 returns to the indoor temperature. The roller shutter door 31 is opened, and the toothed strip drying rack 1, on which the dried toothed strips are placed, is pulled out of the drying chamber 3 from the end of the track via the wire rope hook using the winch unit. Subsequently, the dried toothed strips placed on the toothed strip drying rack 1 can be hoisted to the packaging area.

[0020] The drying principle of the toothed strip: When the toothed strip is produced from the electroplating line, its surface is rich in moisture. When it is placed on the toothed strip drying rack 1, some of the moisture will naturally flow down through the drain tray 2. Subsequently, in the drying chamber 3, the natural gas nozzle is ignited to ensure that the drying temperature is reached in the drying chamber 3. The temperature control fan 44 affects the temperature of the entire drying chamber 3 through airflow to achieve uniform temperature. The temperature in the drying chamber 3 dries all the remaining moisture on the surface of the toothed strip.

[0021] The toothed bar drying rack 1 is provided with a reinforcing support plate 5, and multiple drying fixing mechanisms 6 are arranged in an array on the reinforcing support plate 5. The drying fixing mechanisms 6 are used to support multiple toothed bars during drying.

[0022] Please see Figures 4 to 15 The drying and fixing mechanism 6 includes a rotating shaft 61, a supporting circular plate 62, a circular frame 63, and a closing and clamping mechanism 7. One end of the rotating shaft 61 passes through the reinforcing support plate 5, and the rotating shaft 61 is rotatably connected to the reinforcing support plate 5. A rotating drive component 64 is connected to one end of the rotating shaft 61 located on the back of the reinforcing support plate 5. The rotary drive component 64 includes a rotary block 641 and rotary fan blades 642. The rotary block 641 is fixedly installed at one end of the rotary shaft 61. Multiple rotary fan blades 642 are provided, and are evenly distributed on the outer side of the rotary block 641. In this application, during the drying process of the toothed rod inside the drying chamber 3, the temperature control fan 44 continuously operates along with the operation of the main natural gas heating nozzle 42 and the auxiliary natural gas heating nozzle 43. As the temperature control fan 44 operates, it keeps the temperature-controlled airflow inside the drying chamber 3... The wind force generated by the heating airflow can ensure that the heating airflow drives the rotating fan blade 642, thereby enabling the rotating fan blade 642 to rotate fully. Furthermore, the mutual turbulence between multiple rotating fan blades 642 further accelerates the airflow at the toothed rack 1, thereby causing the fan blades to drive the rotating shaft 61 to rotate fully. Meanwhile, the rotating drive 64 in this application is suitable for drying smaller toothed racks. If larger toothed racks are being dried, the rotating drive is electrically driven to drive the rotating shaft 61. The other end of the rotating shaft 61 is fixedly connected to the supporting circular plate 62, and the circular frame 63 is fixedly connected to the supporting circular plate 62. The circular frame 63 is provided with multiple arc-shaped grooves 631, and the toothed strip is located at the arc-shaped grooves 631. In this application, multiple open arc-shaped grooves 631 are provided on the circular frame 63, which can ensure that the toothed strip is not only fixed during the drying process, but also that the hot airflow is fully distributed on the outside of the toothed strip, so as to achieve efficient drying of the toothed strip. A prepositioning element 65 is provided at the position of the supporting circular plate 62 corresponding to the arc groove 631, and the prepositioning element 65 is used to position one end of the toothed bar; Please see Figures 10 to 15 The closing clamping mechanism 7 is mounted on the circular frame 63, and the closing clamping mechanism 7 cooperates with multiple arc-shaped grooves 631 to clamp the other end of the toothed bar at the arc-shaped grooves 631.

[0023] Please see Figures 7 to 10 An arc-shaped opening 632 is provided on the circular frame 63 at the position corresponding to the arc-shaped groove 631. A lifting frame 8 is slidably connected to the arc-shaped opening 632, and multiple arc-shaped inclined plates 81 are provided on the lifting frame 8. The multiple arc-shaped inclined plates 81 form inclined openings 811 with each other. Multiple ventilation holes are provided on the arc-shaped inclined plates 81. This arrangement can be applied to the continuous threaded protrusions on the outside of the toothed bar, and can generate irregular airflow for the threaded protrusions of the pressure bar, so as to fully dry the toothed bar. A synchronous guide 82 is fixedly connected to one side of the lifting frame 8, and a limiting support 83 is provided on the outer side of the supporting circular plate 62. The limiting support 83 is installed on the reinforcing support plate 5 and is used to limit the multiple synchronous guides 82.

[0024] The limiting support member 83 includes a limiting sleeve 831, which is located outside the supporting circular plate 62 and is sleeved on the outside of the rotating shaft 61. The limiting sleeve 831 is fixedly installed on the reinforcing support plate 5. A continuous V-groove 832 is provided around the outside of the limiting sleeve 831, and the synchronous guide member 82 is connected to the V-groove 832.

[0025] The synchronous guide 82 includes an extension plate 821 and a guide rod 822. The extension plate 821 is L-shaped, and one end of the extension plate 821 is fixedly connected to the support frame 8. A movable opening is provided on the support circular plate 62 at a position corresponding to the extension plate 821. The extension plate 821 slides through the movable opening, and the other end of the extension plate 821 is fixedly connected to the guide rod 822. The guide rod 822 is slidably connected to the V-groove 832.

[0026] Specific implementation process: In this application, during the drying of the toothed strip, due to the positioning action of the prepositioning member 65, the toothed strip fixed at the arc groove 631 does not contact the arc groove 631 and the arc opening 632, that is, the toothed strip is in a relatively "suspended" state. When the rotating shaft 61 rotates, it drives the supporting circular plate 62 to rotate. When the supporting circular plate 62 rotates, the toothed strip at the arc groove 631 rotates synchronously. As the circular frame 63 rotates, the lifting frame 8 at the arc opening 632 is limited by the extension plate 821. In this application, while the extension plate 821 rotates, it reciprocates along the V-groove 832 on the limiting sleeve 831 via the guide rod 822, thereby driving the lifting frame 8 to reciprocate along the arc groove 631. As the lifting frame 8 reciprocates, multiple bevels 811 continuously move relative to the pressure strip. The hot airflow exiting the bevels 811 flows around the outside of the toothed strip, achieving a thorough drying effect on the toothed strip. At the same time, the bevels 811 in this application enable the exited airflow to achieve corresponding drying according to the spiral protrusions of the toothed strip. Please see Figures 10 to 15 The closing clamping mechanism 7 includes a surrounding frame 71, a supporting center plate 72, an adjusting component 73, a closing plate 74, and a position fixing component 75. The surrounding frame 71 is slidably sleeved on the outside of the circular frame 63. An arc-shaped protrusion 711 is provided on the surrounding frame 71 at the position corresponding to the arc-shaped groove 631, and a circular insertion port 712 is provided at the arc-shaped protrusion 711. The circular frame 63 is also provided with two connection ports 633. The supporting center plate 72 passes through the two connection ports 633, and both ends of the supporting center plate 72 are fixedly connected to the surrounding frame 71. The adjusting component 73 is provided on the supporting circular plate 62, and the adjusting component 73 is used to adjust the supporting center plate 72. The adjusting component 73 includes an adjusting screw 731 and a rotating block 732. One end of the adjusting screw 731 is rotatably connected to the supporting circular plate 62, and the other end of the adjusting screw 731 is located outside the circular frame 63 and is fixedly connected to the rotating block 732. The supporting center plate 72 is threaded onto the outside of the adjusting screw 731. Then, by rotating the hand-held rotating block 732, the adjusting screw 731 is rotated. When the adjusting screw 731 rotates, it provides driving force to the support center plate 72. As the support center plate 72 is limited by the connection port 633, the support center plate 72 drives the surrounding frame 71 to move along the circular frame 63.

[0027] The arc-shaped protrusion 711 is provided with a groove 713, and the closing plate 74 is slidably connected to the groove 713. The closing plate 74 opens and closes the circular insertion port 712. The position fixing member 75 is provided on the surrounding frame 71, and the position fixing member 75 is used to synchronously adjust multiple closing plates 74.

[0028] As a supplementary explanation, the position fixing component 75 includes an internal gear ring 751, a rotating gear 752, a rotating shaft 753, a movable rack 754, a drive gear 755, a worm gear 756, a worm 757, and a handle 758. The internal gear ring 751 is rotatably connected to the outer periphery of the surrounding frame 71. Multiple rotating shafts 753 are provided. One end of the rotating shaft 753 is rotatably connected to the groove 713. The rotating gear 752 and the drive gear 755 are respectively fixedly sleeved on the outside of the rotating shaft 753. The rotating gear 752 is meshed with the internal gear ring 751. The drive gear 755 is meshed with the movable rack 754. The movable rack 754 is fixedly installed on the closing plate 74. One end of one of the rotating shafts 753 extends to the other side of the surrounding frame 71, and the worm gear 756 is fixedly installed on the rotating shaft 753. The surrounding frame 71 is provided with a protective shell, and the worm 757 is rotatably connected to the protective shell. The worm 757 is meshed with the worm gear 756, and the handle 758 is fixedly installed on one end of the worm 757. Specific implementation process: When multiple toothed rods are placed into the arc-shaped grooves 631 of the circular frame 63, one end of the toothed rod is inserted into the prepositioning member 65 through the circular insertion port 712. The prepositioning member 65 then performs initial positioning of the toothed rod. Subsequently, when multiple toothed rods are placed, the handle 758 is turned to rotate the worm gear 757, which in turn drives the worm wheel 756 to rotate, further causing one of the rotating shafts 753 to rotate. When the rotating shaft 753 rotates, it drives the rotating gear 752 to rotate, thereby causing the inner gear ring 751 to rotate synchronously. At this time, multiple rotating gears 752 rotate inside the groove 713. When the rotating gears 752 rotate, they drive the gear 755 to rotate, and by moving the rack 754, the closing plate 74 moves along the circular insertion port 712, thereby achieving the function of closing the circular insertion port 712. Subsequently, manually drive the rotating block 732 to move the circular frame 63 toward the multiple toothed bars until the multiple closing plates 74 at the circular frame 63 and the supporting circular plate 62 clamp and fix the toothed bars. In this state, it can be ensured that the toothed bars can be stably dried on the toothed bar drying rack 1.

[0029] Example 2 Please see Figures 7 to 8 Example 2 further supplements the description of the prepositioning component 65 in Example 1. Specifically, the prepositioning component 65 includes a positioning plate 651, a moving block 652, and a buffer spring 653. Multiple positioning plates 651 are provided, and the multiple positioning plates 651 are located at one end of the arc groove 631. The multiple positioning plates 651 are slidably connected to the supporting circular plate 62. The other side of the positioning plate 651 is fixedly connected to the moving block 652. The supporting circular plate 62 is provided with a positioning port corresponding to the position of the moving block 652. The moving block 652 slides through the positioning port. One end of the buffer spring 653 is fixedly connected to the inner wall of the positioning port, and the other end of the buffer spring 653 is fixedly connected to the moving block 652. The positioning plate 651 in this application has an inclined surface at one end facing the circular frame 63, and the setting of the inclined surface facilitates the insertion of one end of the toothed bar between multiple positioning plates 651. Specifically, when drying the toothed strip, one end of the toothed strip is inserted into the arc-shaped groove 631 through the circular insertion port 712. The circular insertion port 712 ensures that the pressure strip is located between the multiple positioning plates 651 at the arc end. Once one end of the toothed strip is inserted between the multiple positioning plates 651, the multiple positioning plates 651 initially clamp and position one end of the toothed strip under the connecting action of the buffer spring 653.
