[0016] In summary, the present invention mainly has the following beneficial effects: This design achieves efficient, uniform and safe drying of resin crafts by setting a drying rack and the synergistic effect of hot air conveying components, rotating components, mesh gauze and exhaust system. According to the shape and size of the crafts, they can be flexibly placed vertically or horizontally on the drying grid. The mesh gauze can be tightly covered on the surface of the crafts through the positioning bracket to prevent the displacement of the crafts due to gravity or centrifugal force during the drying process, thereby ensuring its stability. The hot air flow is guided to the top and bottom of the drying rack through the movable tube and the fixed tube, and is first divided by the mesh gauze to evenly cover the surface of the crafts, while reducing the intensity of the direct impact of the hot air to avoid local overheating or damage. The dividing effect of the mesh gauze not only increases the coverage rate of the hot air on the crafts, but also has a certain filtering effect, which can block impurities attached to the hot air during the drying process, ensure the cleanliness of the air flow, reduce the risk of pollution, and improve the appearance quality of the finished product. The rotating component rotates the connecting shaft intermittently, so that the drying rack and the crafts on it change their angles continuously, so that the hot air flow can fully cover all sides of the crafts, especially the hidden recessed parts and shielded areas, to avoid insufficient or excessive drying. In addition, in the gap when the connecting shaft stops rotating, the mesh gauze is allowed to leave the crafts to avoid long-term coverage leading to local heat accumulation and uneven drying. At the same time, the air is disturbed to promote the exchange of moist air and dry air, accelerate the discharge of moisture, and further improve the drying efficiency. The timely discharge of moist air avoids the secondary moisture absorption phenomenon on the surface of the crafts, ensuring a more thorough drying effect. Dynamic rotation avoids the mesh gauze from being fixed for a long time, reduces the accumulation of material fatigue, and prolongs its service life. The continuous operation of the exhaust fan enhances the air flow in the drying box, stably discharges moist air, forms a good cycle with the hot air flow, optimizes the internal air circulation environment, and improves the drying efficiency and uniformity. This design ensures that the resin crafts can be dried under dynamic heating conditions, solving the problem that most equipment in the prior art adopts a single ventilation structure design, and the hot air only flows along a fixed path. When faced with crafts with complex shapes, it is difficult to effectively cover all surfaces, especially recessed parts and blocked areas, which leads to uneven drying problems.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] refer to Figure 1-Figure 12 , a drying device for processing resin handicrafts, comprising: A drying box 100, a ventilation port 101 is provided at the bottom of the drying box 100, and a plurality of exhaust fans 102 are provided in the ventilation port 101 for exhausting the gas in the drying box 100 from the ventilation port 101; A connecting shaft 103 provided on the drying box body 100; A drying rack 104 is disposed on the connecting shaft 103, and the drying rack 104 has a plurality of drying grids 105; Two drying ducts 106 are provided on the drying box 100, one of which is provided with a movable pipe 107, and the other is provided with a fixed pipe 108 for conveying hot air, and the movable pipe 107 and the fixed pipe 108 are respectively provided with hot air openings 109 facing the drying rack 104; A mesh gauze 110 is arranged on a drying rack 104, and a positioning bracket 111 is arranged on the drying rack 104; The hot air conveying component provided on the drying box 100 is used to output the hot air into the drying duct 106; The positioning component disposed between the drying rack 104 and the positioning bracket 111 is used to press the mesh gauze 110 to make it tight on the drying rack 104 when the positioning bracket 111 moves downward to a preset position. When the positioning bracket 111 moves downward, the movable tube 107 can move with it; The rotating component disposed between the drying boxes 100 is used to intermittently rotate the connecting shaft 103 to adjust the angle of the drying rack 104; Wherein, the rotating component can move the positioning bracket 111 downward when the connecting shaft 103 is about to be rotated; The rotating component can also continuously rotate the plurality of exhaust fans 102 while intermittently rotating the connecting shaft 103; The positioning bracket 111 can allow the mesh gauze 110 to rotate on the drying rack 104 when it moves downward to a preset position and then returns upward; By setting up the drying rack 104, when it is used, the resin crafts can be selectively placed vertically or horizontally on the drying grid 105 according to their shapes and sizes, and the hot air conveying component is started. The hot air conveying component outputs the hot air flow into the two drying pipes 106, and is guided by the drying pipes 106, the movable pipe 107, and the fixed pipe 108 to blow to the bottom and the top of the drying rack 104. During drying, the rotating component intermittently rotates the connecting shaft 103. When the connecting shaft 103 is about to rotate, the position of the positioning bracket 111 can be moved downward, so that the mesh gauze 110 is deformed. When the positioning bracket 111 moves downward to the preset position, the positioning component can press a section of mesh gauze 110 located on the top of the drying rack 104, so that it is deformed and covers the resin crafts in the drying grid 105. At this time, the taut mesh gauze 110 can fix the crafts on the drying grid 105 to prevent the crafts from being displaced due to gravity or centrifugal force during the subsequent rotation process, thereby ensuring the stability of the crafts. In addition, when the fixed tube 108 and the movable tube 107 blow hot air flow to the drying rack 104, the hot air flow will first pass through the mesh gauze 110 before reaching the handicraft, and the mesh gauze 110 can divide the hot air flow so that the hot air flow is dispersed into a plurality of small air flow beams, thereby evenly covering the surface of the resin handicraft. This design not only improves the coverage rate of the handicraft with hot air, but also slows down the direct impact of the hot air, avoiding local overheating or damage to the surface of the handicraft. The hot air flow after division can more efficiently penetrate into the recessed parts and complex structures of the handicraft, further improving the uniformity and comprehensiveness of drying. In addition, the mesh gauze 110 also plays a certain filtering effect, which can block the impurities that may be attached to the hot air during the drying process, and ensure that the air flow blowing to the handicraft is cleaner, thereby reducing the risk of pollution and improving the appearance quality of the finished product. When the rotating part rotates the connecting shaft 103, the drying rack 104 can drive the handicraft on it to change its angle, while the positions of the fixed tube 108 and the movable tube 107 do not change. This design can adjust the position of the handicraft so that the hot air flow can cover all sides of the handicraft, including the hidden recessed parts and the shielding area, so as to achieve a comprehensive and uniform drying effect. Through the rotation adjustment, the handicraft is always in a dynamic heating state during the drying process, avoiding the situation where the fixed position causes insufficient or excessive drying of certain areas. After the rotating part rotates the connecting shaft 103 to the preset angle each time, it will stop for a period of time. During this process, the positioning bracket 111 will reset. When the positioning bracket 111 can reset upward after moving downward to the preset position, it can allow the mesh gauze 110 to rotate on the drying rack 104. The purpose of this design is to restore a section of the mesh gauze 110 at the top of the drying rack 104 to its original state and leave the handicraft. At this time, the moist air generated by drying around the handicraft can overflow, thereby further reducing the humidity around the handicraft and improving the drying efficiency.The timely discharge of moist air can also avoid the secondary moisture absorption phenomenon on the surface of the handicraft due to moisture retention, ensuring that the drying effect is more thorough. The rotating action of the mesh gauze 110 can disturb the air around the handicraft, so that the moist air is exchanged with the dry air faster, while avoiding the formation of a local air retention area. The mesh gauze 110 is prevented from being fixed for a long time by dynamic rotation, the accumulation of material fatigue is reduced, and its service life is extended. This dynamic operation of the mesh gauze 110 not only improves the utilization efficiency of hot air, but also reduces the risk of local heat accumulation and uneven drying that may be caused by long-term coverage. Further, the rotating component can also continuously rotate multiple exhaust fans 102 while intermittently rotating the connecting shaft 103, enhance the air flow effect in the drying box 100, accelerate the discharge of moist air, and when the connecting shaft 103 stops rotating and the mesh gauze 110 leaves the handicraft, a stable time window is provided for the discharge of moist air, and the synergy with the exhaust fan 102 further optimizes the air circulation environment inside the drying box 100. This design ensures the circulation speed of hot air, so that the humidity environment around the crafts is always low, further improving the drying efficiency and uniformity.

[0021] As a further solution of the present invention, the positioning component includes a plurality of guide shafts a200 connected to the bottom of the drying rack 104, a plurality of guide shafts b201 are arranged on the top of the drying rack 104, the mesh gauze 110 bypasses the guide shafts a200 and is sleeved on the drying rack 104 with the guide shafts b201, a multi-stage spring telescopic rod 202 is connected to the top of the drying rack 104, a plurality of elastic telescopic rods 203 are connected to the positioning bracket 111, the bottom two sides of the positioning bracket 111 are respectively connected to positioning rods 204, the elastic telescopic rod 203 is located between the two positioning rods 204, a plurality of positioning ribs 205 adapted to the positioning rods 204 and the elastic telescopic rods 203 are connected to the drying rack 104, the plurality of positioning ribs 205 separate the top of the drying rack 104 into a plurality of drying grids 105, the plurality of elastic telescopic rods 203 have different lengths, wherein the length of the elastic telescopic rod 203 adjacent to the positioning rod 204 is greater than the positioning rod 204, and the length of the elastic telescopic rod 203 gradually increases in the direction toward the connecting shaft 103; By setting the guide shaft a200, the guide shaft b201, and the multi-stage spring telescopic rod 202, the mesh gauze 110 can be supported on the drying rack 104 and the mesh gauze 110 can be limited. The elastic potential energy of the elastic telescopic rod 203 is greater than that of the multi-stage spring telescopic rod 202, and the lengths of the multiple elastic telescopic rods 203 are different. The length of the elastic telescopic rod 203 adjacent to the positioning rod 204 is greater than that of the positioning rod 204, and the length of the elastic telescopic rod 203 gradually increases in the direction toward the connecting shaft 103. When the positioning bracket 111 moves downward, the elastic telescopic rod 203 close to the connecting shaft 103 will first contact the mesh gauze 110 and press the mesh gauze 110. Since the length of the mesh gauze 110 remains unchanged, at this time, the multi-stage spring telescopic rod 202 moves downward due to a section of the mesh gauze 110, and the multi-stage spring telescopic rod 202 contracts, releasing the mesh gauze 110. As the positioning bracket 111 moves downward, the mesh gauze 110 gradually forms a taut state covering the drying grid 105 under the pressure of the multiple elastic telescopic rods 203, which can stably fix the handicraft in the drying grid 105 to prevent displacement due to rotation or vibration. After the positioning bracket 111 is completely moved downward to the preset position, the force of the mesh gauze 110 is evenly distributed on the surface of the handicraft, which can prevent the handicraft from being separated from the drying grid 105 due to gravity or centrifugal force during rotation.

[0022] As a further solution of the present invention, the positioning component also includes a traction bar 206 slidably connected to both sides of the drying rack 104, a side opening 207 is opened on one side of the traction bar 206, the mesh gauze 110 passes through the side opening 207, and the top and bottom of the side opening 207 are respectively slidably connected with a clamping plate 208, and the traction bar 206 is rotatably connected with a screw a209, and the clamping plate 208 is threadedly connected to the screw a209; By setting the traction bar 206, the lead screw a209 can be rotated first in application to allow the two clamping plates 208 in the side opening 207 to move closer to each other until the mesh gauze 110 is clamped. Subsequently, by pushing the traction bar 206 to slide along the drying rack 104, the mesh gauze 110 can be pulled to rotate on the drying rack 104. The purpose of rotating the mesh gauze 110 on the drying rack 104 can be achieved. By dynamically rotating the mesh gauze 110 to avoid being fixed for a long time and being stressed, the accumulation of material fatigue can be reduced and its service life can be extended.

[0023] As a further solution of the present invention, the positioning component also includes a screw b300 rotatably connected to the connecting shaft 103, a spring a301 is connected between the screw b300 and the connecting shaft 103, a positioning bracket 111 is slidably connected to the connecting shaft 103, and is threadedly connected to the screw b300, both sides of the drying rack 104 are rotatably connected to the screw c302, the traction bar 206 is threadedly connected to the screw c302, the screw c302 is connected to the traction shaft 303, the spring b304 is connected between the traction shaft 303 and the drying rack 104, a traction rope 305 is wound on the traction shaft 303, one end of the traction rope 305 is connected to the positioning bracket 111, a rack 306 is connected to one side of the drying rack 104, and a gear a307 meshing with the rack 306 is connected to the screw a209; By setting the lead screw b300, when in use, the lead screw b300 can be rotated before the connecting shaft 103 rotates, and the lead screw b300 rotates to move the position of the positioning bracket 111 downward, and allows the spring a301 to generate potential energy. When the positioning bracket 111 moves downward to the extreme position to allow the mesh gauze 110 to be tightened on the drying rack 104, if the lead screw b300 continues to be rotated, the connecting shaft 103 can be rotated at this time. In the initial state, the spring b304 is in a torsion state and has potential energy. When the positioning bracket 111 moves downward, the traction shaft 303 is no longer pulled, and the traction shaft 303 and the lead screw c302 can rotate due to the potential energy of the spring b304. At this time, the traction bar 206 moves along the thread track of the lead screw c302, and the gear a307 and the lead screw a209 are acted upon by the rack 306 to move the clamping plate 208 to clamp the mesh gauze 110. With the movement of the traction bar 206, the mesh gauze 110 can be displaced on the drying rack 104. When the lead screw b300 stops rotating later, the lead screw b300 is reset and rotated due to the potential energy of the spring a301, so that the positioning bracket 111 moves upward, and the traction rope 305 pulls the traction shaft 303 to rotate, so that the traction bar 206 can be reset. When the traction bar 206 is reset, the gear a307 rotates in the opposite direction, releasing the clamping of the clamping plate 208 on the mesh gauze 110, loosening the mesh gauze 110, and returning to the initial position to prepare for the next round of rotation of the mesh gauze 110. This design allows the device to efficiently and accurately adjust the position of the mesh gauze 110 and achieve continuous cyclic work.

[0024] As a further solution of the present invention, the inner wall of the gear a307 is provided with a plurality of top grooves 308, the outer wall of the lead screw a209 is provided with a plurality of connecting grooves 309, a top rod 310 is slidably connected in the connecting groove 309, a spring c311 is connected between the top rod 310 and the connecting groove 309, the top groove 308 is a semi-spherical groove, and one end of the top rod 310 that cooperates with the top groove 308 is semi-spherical; By setting the spring c311, the spring c311 can apply a matching force to the top rod 310 and the top groove 308, and form a certain friction force between the top rod 310 and the top groove 308. When the gear a307 is rotated by the rack 306, the friction force can be used to rotate the lead screw a209. After the two clamps 208 move to the limit position to clamp the mesh gauze 110, the rotation of the lead screw a209 is restricted. With the continuous movement of the traction bar 206, the rotation of the gear a307 can overcome the friction force applied by the spring c311, so that the top groove 308 and the top rod 310 are separated, and the gear a307 idles outside the lead screw c302, avoiding stagnation and ensuring the smooth operation of the system. In addition, when the subsequent traction bar 206 moves back to the original position, the friction force provided by the spring c311 can be used to timely allow the lead screw a209 to rotate in the opposite direction, and the mesh gauze 110 can be loosened in time to prepare for the next rotation of the mesh gauze 110.

[0025] As a further solution of the present invention, the rotating component includes a motor 400 disposed at the bottom of the drying box 100, a gear b401 is connected to the driving shaft of the motor 400, a transmission shaft 402 is connected to the exhaust fan 102, and the bottom of the transmission shaft 402 passes through the drying box 100 and is connected to a gear c403 meshing with the gear b401; By setting the motor 400, when in use, the motor 400 can be turned on, and the driving shaft of the motor 400 can rotate through the gear b401 and the gear c403 to rotate the transmission shaft 402. The rotation of the transmission shaft 402 can drive the exhaust fan 102 to rotate. As the exhaust fan 102 rotates, the humid air in the box is discharged in time, which helps to evenly dry the handicrafts and avoid affecting the drying effect due to moisture retention.

[0026] As a further solution of the present invention, the rotating component also includes a gear d404 connected to the lead screw b300, a rotating shaft 405 is connected to the bottom of the drying box 100, a gear e406 adapted to the gear d404 is connected to the rotating shaft 405, the gear e406 is an incomplete gear, and a chain transmission mechanism 407 is provided between the rotating shaft 405 and one of the transmission shafts 402; By setting the chain transmission mechanism 407, when the gear b401 rotates, the gear b401, gear c403, and chain transmission mechanism 407 can rotate the shaft 405. When the shaft 405 rotates to a preset angle, the gear e406 can mesh with the gear d404, and the gear d404 can rotate with the lead screw b300. After the lead screw b300 rotates by a preset angle to move the positioning bracket 111 downward to the limit position, the lead screw b300 can rotate the connecting shaft 103 when the lead screw b300 continues to rotate until the gear e406 is disengaged from the gear d404, so as to achieve the purpose of rotating the lead screw b300 to move the positioning bracket 111 when the connecting shaft 103 is about to rotate, positioning the handicrafts in the drying grid 105 through the positioning component, and intermittently rotating the connecting shaft 103. In this process, the angle of the drying rack 104 is adjusted so that the handicrafts can be evenly covered by hot air.
