Description

Technical Field

[0001] This invention relates to the field of resin product drying technology, specifically to a drying apparatus and method for processing resin handicrafts. Background Technology

[0002] Resin crafts, with their advantages of being lightweight, highly malleable, and diverse in appearance, have been widely used in home decoration, gift making, and other fields. Because resin material has excellent processing properties, it can be molded into products of various shapes and rich details, thus gaining widespread market popularity.

[0003] However, to ensure the quality of resin crafts, a series of complex and rigorous processes are required during production, among which the drying process is particularly critical.

[0004] Hot air drying is a widely used technique in the production of resin crafts. It mainly relies on the flow of hot air within the drying chamber to rapidly evaporate and remove moisture and volatile components from the surface of the product. Most existing equipment uses a single ventilation structure design, with hot air flowing only along a fixed path. For crafts with complex shapes, it is difficult to effectively cover all surfaces, especially recessed areas and obstructed areas, leading to uneven drying. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a drying apparatus and method for processing resin handicrafts, aiming to alleviate the aforementioned problems to at least some extent.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A drying apparatus for processing resin handicrafts, comprising:

[0008] The drying chamber has an air vent at the bottom and multiple exhaust fans inside the air vent to exhaust the gas inside the drying chamber.

[0009] The connecting shaft is located on the drying chamber.

[0010] A drying rack is mounted on the connecting shaft, and the drying rack has multiple drying compartments;

[0011] Two drying pipes are provided on the drying chamber, one of which has a movable pipe and the other has a fixed pipe for conveying hot air. The movable pipe and the fixed pipe are respectively provided with hot air openings facing the drying rack.

[0012] A mesh gauze is placed on the drying rack, and the drying rack is provided with a positioning bracket;

[0013] A hot air conveying component installed on the drying chamber is used to output hot air into the drying duct;

[0014] A positioning component located between the drying rack and the positioning bracket is used to press the mesh gauze to tighten it on the drying rack when the positioning bracket moves downward to a preset position. When the positioning bracket moves downward, the movable tube can follow the movement.

[0016] The rotating component is capable of moving the positioning bracket downwards when the connecting shaft is about to rotate;

[0017] The rotating component is also capable of continuously rotating multiple exhaust fans while intermittently rotating the connecting shaft;

[0018] The positioning bracket allows the mesh gauze to rotate on the drying rack when it moves downward to a preset position and then returns to its original position.

[0019] Preferably, the positioning component includes multiple guide shafts a connected to the bottom of the drying rack, multiple guide shafts b provided at the top of the drying rack, the mesh gauze wrapped around the guide shafts a and b and sleeved on the drying rack, a multi-stage spring telescopic rod connected to the top of the drying rack, multiple elastic telescopic rods connected to the positioning bracket, positioning rods connected to the bottom two sides of the positioning bracket, the elastic telescopic rods located between two positioning rods, multiple positioning ribs adapted to the positioning rods and the elastic telescopic rods connected to the drying rack, the multiple positioning ribs dividing the top of the drying rack into multiple drying compartments, the multiple elastic telescopic rods having different lengths, wherein the elastic telescopic rods adjacent to the positioning rods are longer than the positioning rods, and the length of the elastic telescopic rods gradually increases along the direction towards the connecting shaft.

[0020] Preferably, the positioning component further includes traction bars slidably connected to both sides of the drying rack. A side opening is provided on one side of the traction bar, through which the mesh gauze passes. Clamping plates are slidably connected to the top and bottom of the side opening, respectively. A lead screw a is rotatably connected to the traction bar, and the clamping plate is threadedly connected to the lead screw a.

[0021] Preferably, the positioning component further includes a lead screw b rotatably connected to the connecting shaft, a spring a connected between the lead screw b and the connecting shaft, a positioning bracket slidably connected to the connecting shaft and threadedly connected to the lead screw b, lead screws c rotatably connected to both sides of the drying rack, a traction bar threadedly connected to the lead screw c, a traction shaft connected to the lead screw c, a spring b connected between the traction shaft and the drying rack, a traction rope wound on the traction shaft, one end of the traction rope connected to the positioning bracket, a rack connected to one side of the drying rack, and a gear a connected to the lead screw a that meshes with the rack.

[0022] Preferably, the inner wall of the gear a is provided with multiple top grooves, the outer wall of the lead screw a is provided with multiple connecting grooves, a push rod is slidably connected in the connecting groove, a spring c is connected between the push rod and the connecting groove, the top groove is a hemispherical groove, and the end of the push rod that mates with the top groove is a hemispherical shape.

[0023] Preferably, the rotating component includes a motor located at the bottom of the drying chamber, a gear b connected to the drive shaft of the motor, a transmission shaft connected to the exhaust fan, and the bottom of the transmission shaft passing through the drying chamber and connected to a gear c that meshes with the gear b.

[0024] Preferably, the rotating component further includes a gear d connected to the lead screw b, a rotating shaft connected to the bottom of the drying chamber, a gear e adapted to the gear d connected to the rotating shaft, the gear e being an incomplete gear, and a chain drive mechanism provided between the rotating shaft and one of the transmission shafts.

[0025] Preferably, the hot air conveying component includes a hot air blower located on one side of the drying chamber, and a conveying pipe is connected to the air outlet of the hot air blower, and the drying pipe is connected to the conveying pipe.

[0026] Preferably, the hot air conveying component further includes a connection port opened on one side of one of the drying pipes, the movable tube is slidably connected to the connection port, a sealing tube slidably connected to the drying pipe is connected to the movable tube to cover the connection port, a follower frame is rotatably connected to the positioning bracket, and a portion of the movable tube extending to the top of the positioning bracket is inserted into the follower frame.

[0027] A method for drying resin handicrafts, applicable to the drying apparatus for processing resin handicrafts as described in any of the above claims, comprises the following steps:

[0028] Step 1: Depending on the shape and size of the resin crafts, selectively place them vertically or horizontally on the drying rack, ensuring that the crafts are securely placed in the drying compartment, and prepare to start the equipment;

[0029] Step 2: Start the hot air conveying component. The hot air flow enters from the hot air blower through the drying pipe, and then passes through the movable pipe and the fixed pipe, guiding the hot air flow to the bottom and top of the drying rack to ensure that the hot air can evenly cover the surface of the crafts.

[0030] Step 3: Driven by the rotating component, the connecting shaft is rotated intermittently. Just as the connecting shaft is about to rotate, the positioning bracket moves downward to the preset position. The positioning component will press the mesh gauze to ensure that it deforms and covers the craft, thereby fixing the craft and preventing displacement during rotation.

[0031] Step 4: Under the action of the rotating parts, the drying rack rotates with the rotation of the connecting shaft, the angle of the handicraft changes, and the hot air can fully cover all surfaces of the handicraft, including its concave parts and obstructed areas.

[0032] Step 5: After each rotation to the preset angle, the connecting shaft will pause for a period of time. At this time, the positioning bracket will return to its original position and allow the mesh fabric to leave the craft, allowing the humid air to escape.

[0033] Step Six: After the drying process is complete, use the motor to adjust the position of the drying rack, remove the crafts from the drying rack, and place new resin crafts on top.

[0034] In summary, the present invention has the following main beneficial effects:

[0035] This invention achieves efficient, uniform, and safe drying of resin crafts through the synergistic effect of a drying rack, hot air conveying components, rotating parts, mesh fabric, and exhaust system. Depending on the shape and size of the crafts, they can be flexibly placed vertically or horizontally on the drying rack. The mesh fabric, secured by positioning supports, tightly covers the surface of the crafts, preventing displacement due to gravity or centrifugal force during drying and ensuring stability. Hot air is guided to the top and bottom of the drying rack through movable and fixed pipes, and is first divided by the mesh fabric, evenly covering the surface of the crafts while reducing the intensity of direct hot air impact, preventing localized overheating or damage. The dividing effect of the mesh fabric not only improves the coverage of hot air on the crafts but also has a certain filtering effect, blocking impurities adhering to the hot air during drying, ensuring clean airflow, reducing the risk of contamination, and improving the appearance quality of the finished product. The rotating component, through intermittent rotation of the connecting shaft, continuously changes the angle of the drying rack and the crafts on it. This ensures that the hot airflow comprehensively covers all surfaces of the crafts, especially hidden recesses and obstructed areas, preventing under-drying or over-drying. Furthermore, during the intervals when the connecting shaft stops rotating, the mesh fabric is removed from the crafts, preventing prolonged covering that could lead to localized heat buildup and uneven drying. Simultaneously, the agitated airflow promotes the exchange of humid and dry air, accelerating moisture removal and further improving drying efficiency. Timely removal of humid air prevents secondary moisture absorption from the crafts surface, ensuring a more thorough drying effect. Dynamic rotation prevents the mesh fabric from being fixed under stress for extended periods, reducing material fatigue and extending its lifespan. The continuously operating exhaust fan enhances airflow within the drying chamber, stably expelling humid air and creating a good circulation with the hot airflow. This optimizes the internal air circulation environment, improving drying efficiency and uniformity. This design ensures that resin crafts can be dried under dynamic heating conditions, overcoming the limitations of most existing equipment that uses a single ventilation structure where hot air flows only along a fixed path. When dealing with complex-shaped handicrafts, it is difficult to effectively cover all surfaces, especially recessed areas and obscured areas, leading to uneven drying. Attached Figure Description

[0053] 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.

[0054] refer to Figures 1-12 A drying apparatus for processing resin handicrafts, comprising:

[0055] The drying chamber 100 has an air vent 101 at the bottom and multiple exhaust fans 102 inside the air vent 101 to exhaust the gas inside the drying chamber 100 from the air vent 101.

[0056] A connecting shaft 103 is provided on the drying chamber 100;

[0057] A drying rack 104 is provided on the connecting shaft 103, and the drying rack 104 has a plurality of drying compartments 105;

[0058] Two drying pipes 106 are provided on the drying chamber 100. One drying pipe 106 is provided with a movable pipe 107 and the other drying pipe 106 is provided with a fixed pipe 108 for conveying hot air. The movable pipe 107 and the fixed pipe 108 are respectively provided with hot air openings 109 facing the drying rack 104.

[0059] A mesh gauze 110 is provided on a drying rack 104, and a positioning bracket 111 is provided on the drying rack 104;

[0060] A hot air conveying component installed on the drying chamber 100 is used to output hot air into the drying duct 106;

[0061] The positioning component located between the drying rack 104 and the positioning bracket 111 is used to press the mesh gauze 110 to tighten it on the drying rack 104 when the positioning bracket 111 moves downward to the preset position. When the positioning bracket 111 moves downward, the movable tube 107 can move accordingly.

[0062] A rotating component located between the drying chambers 100 is used to intermittently rotate the connecting shaft 103 to adjust the angle of the drying rack 104;

[0063] The rotating component is able to move the positioning bracket 111 downward when the connecting shaft 103 is about to rotate.

[0064] The rotating component can also continuously rotate multiple exhaust fans 102 while intermittently rotating the connecting shaft 103;

[0065] Among them, the positioning bracket 111 can rotate the mesh gauze 110 on the drying rack 104 when it moves downward to the preset position and then moves upward to reset;

[0066] By setting up the drying rack 104, during application, resin crafts can be selectively placed vertically or horizontally on the drying compartment 105 according to their shape and size. The hot air conveying component is then activated, outputting hot air flow into the two drying pipes 106. The hot air is guided by the drying pipes 106, the movable pipe 107, and the fixed pipe 108, blowing towards the bottom and top of the drying rack 104. During drying, the rotating component intermittently rotates the connecting shaft 103. Just before the connecting shaft 103 is about to rotate, the positioning bracket 111 can be moved downward, causing the mesh gauze 110 to deform. When the positioning bracket 111 moves downward to the preset position, the positioning component can press the section of mesh gauze 110 located at the top of the drying rack 104, causing it to deform and cover the resin crafts in the drying compartment 105. At this time, the taut mesh gauze 110 can fix the crafts on the drying compartment 105, preventing the crafts from shifting due to gravity or centrifugal force during subsequent rotation, thus ensuring the stability of the crafts. Furthermore, when the fixed pipe 108 and the movable pipe 107 blow hot air into the drying rack 104, the hot air first passes through the mesh fabric 110 before reaching the crafts. The mesh fabric 110 can segment the hot air flow, dispersing it into multiple fine airflow beams, thereby evenly covering the surface of the resin crafts. This design not only improves the coverage of the hot air on the crafts but also reduces the direct impact of the hot air, avoiding localized overheating or damage to the surface of the crafts. The segmented hot air flow can penetrate more efficiently into the recessed areas and complex structures of the crafts, further improving the uniformity and comprehensiveness of drying. In addition, the mesh fabric 110 also has a certain filtering effect, blocking impurities that may adhere to the hot air during the drying process, ensuring that the airflow blowing towards the crafts is cleaner, thereby reducing the risk of contamination and improving the appearance quality of the finished product. When the rotating component rotates the connecting shaft 103, the drying rack 104 can change the angle of the crafts on it, while the positions of the fixed tube 108 and the movable tube 107 remain unchanged. This design allows the position of the crafts to be adjusted so that the hot airflow can cover all surfaces of the crafts, including hidden recesses and obstructed areas, thereby achieving a comprehensive and uniform drying effect. Through rotational adjustment, the crafts are always in a dynamic heating state during the drying process, avoiding the situation where certain areas are under-dried or over-dried due to a fixed position. After rotating the connecting shaft 103 to a preset angle, the rotating component will pause for a period of time. During this process, the positioning bracket 111 will move back to its original position. When the positioning bracket 111 moves downward to a preset position and then moves upward to reset, it allows the mesh gauze 110 to rotate on the drying rack 104. The purpose of this design is to allow the section of mesh gauze 110 at the top of the drying rack 104 to return to its original state and leave the crafts. At this time, the humid air generated around the crafts due to drying can escape, thereby further reducing the humidity around the crafts and improving the drying efficiency.The timely removal of humid air also prevents secondary moisture absorption caused by moisture retention on the surface of the handicrafts, ensuring a more thorough drying effect. The rotation of the mesh gauze 110 agitates the air around the handicrafts, allowing humid air to exchange with dry air more quickly, while avoiding the formation of localized air stagnation zones. Dynamic rotation prevents the mesh gauze 110 from being fixed under stress for extended periods, reducing material fatigue and extending its service life. This dynamic operation of the mesh gauze 110 not only improves the utilization efficiency of hot air but also reduces the risk of localized heat accumulation and uneven drying that may result from prolonged covering. Furthermore, the rotating components can continuously rotate multiple exhaust fans 102 while intermittently rotating the connecting shaft 103, enhancing the airflow within the drying chamber 100 and accelerating the removal of humid air. When the connecting shaft 103 stops rotating and the mesh gauze 110 leaves the handicrafts, a stable time window for humid air removal is provided, and the synergistic effect with the exhaust fans 102 further optimizes the airflow environment inside the drying chamber 100. This design ensures a high circulation speed of hot air, maintaining a consistently low humidity environment around the crafts, further improving drying efficiency and uniformity.

[0067] As a further embodiment of the present invention, the positioning component includes multiple guide shafts a200 connected to the bottom of the drying rack 104, multiple guide shafts b201 provided on the top of the drying rack 104, mesh gauze 110 passing around the guide shafts a200 and sleeved on the drying rack 104 along with the guide shafts b201, a multi-stage spring telescopic rod 202 connected to the top of the drying rack 104, multiple elastic telescopic rods 203 connected to the positioning bracket 111, positioning rods 204 respectively connected to the bottom two sides of the positioning bracket 111, the elastic telescopic rods 203 located between the two positioning rods 204, multiple positioning ribs 205 adapted to the positioning rods 204 and the elastic telescopic rods 203 connected to the drying rack 104, the multiple positioning ribs 205 dividing the top of the drying rack 104 into multiple drying compartments 105, the lengths of the multiple elastic telescopic rods 203 are different, 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 along the direction toward the connecting shaft 103;

[0068] By setting guide shaft a200, guide shaft b201, and 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. The lengths of the multiple elastic telescopic rods 203 are different. Among them, the elastic telescopic rod 203 adjacent to the positioning rod 204 is longer than the positioning rod 204. The length of the elastic telescopic rod 203 gradually increases along the direction towards the connecting shaft 103. When the positioning bracket 111 moves downward, the elastic telescopic rod 203 near the connecting shaft 103 will first contact the mesh gauze 110 and compress the mesh gauze 110. Since the length of the mesh gauze 110 remains unchanged, the multi-stage spring telescopic rod 202 contracts due to the downward movement of a section of the mesh gauze 110, releasing the mesh gauze 110. As the positioning bracket 111 moves downward, the mesh gauze 110 gradually forms a taut state covering the drying rack 105 under the compression of the multiple elastic telescopic rods 203, which can stably fix the handicrafts in the drying rack 105 and prevent displacement due to rotation or vibration. After the positioning bracket 111 moves completely downward to the preset position, the force on the mesh gauze 110 is evenly distributed on the surface of the craft, which can prevent the craft from falling off the drying rack 105 due to gravity or centrifugal force during rotation.

[0069] As a further embodiment 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 provided on one side of the traction bar 206. The mesh gauze 110 passes through the side opening 207. The top and bottom of the side opening 207 are respectively slidably connected to a clamping plate 208. A lead screw a209 is rotatably connected to the traction bar 206. The clamping plate 208 is threadedly connected to the lead screw a209.

[0070] By setting the traction bar 206, during application, the lead screw a209 can be rotated first to move the two clamping plates 208 inside the side opening 207 closer together until the mesh fabric 110 is clamped. Then, by pushing the traction bar 206 to slide along the drying rack 104, the mesh fabric 110 can be pulled, causing it to rotate on the drying rack 104. This achieves the purpose of rotating the mesh fabric 110 on the drying rack 104. Dynamic rotation avoids prolonged fixed stress on the mesh fabric 110, reducing material fatigue accumulation and extending its service life.

[0071] As a further embodiment of the present invention, the positioning component further includes a lead screw b300 rotatably connected to the connecting shaft 103, a spring a301 connected between the lead screw b300 and the connecting shaft 103, a positioning bracket 111 slidably connected to the connecting shaft 103 and threadedly connected to the lead screw b300, lead screws c302 rotatably connected to both sides of the drying rack 104, a traction bar 206 threadedly connected to the lead screw c302, a traction shaft 303 connected to the lead screw c302, a spring b304 connected between the traction shaft 303 and the drying rack 104, a traction rope 305 wound on the traction shaft 303, one end of the traction rope 305 connected to the positioning bracket 111, a rack 306 connected to one side of the drying rack 104, and a gear a307 meshing with the rack 306 connected to the lead screw a209.

[0072] By setting the lead screw b300, during application, the lead screw b300 can be rotated before the connecting shaft 103 rotates. The lead screw b300 rotates and moves the position of the positioning bracket 111 downward, and the spring a301 generates potential energy. When the positioning bracket 111 moves downward to the limit position so that the mesh gauze 110 is taut on the drying rack 104, if the lead screw b300 is rotated further, the connecting shaft 103 can be rotated. Initially, spring b304 is in a torsional state and possesses potential energy. When the positioning bracket 111 moves downward, it no longer pulls on the traction shaft 303. The traction shaft 303 and the lead screw c302 can rotate due to the potential energy of spring b304. At this time, the traction bar 206 moves along the threaded trajectory of the lead screw c302. The gear a307 and the lead screw a209, under the action of the rack 306, cause the clamping plate 208 to move and clamp the mesh fabric 110. As the traction bar 206 moves, it can drive the mesh fabric 110 to move on the drying rack 104. When the lead screw b300 stops rotating, the lead screw b300 is reset by the potential energy of spring a301, causing the positioning bracket 111 to move upward. The traction rope 305 pulls the traction shaft 303 to rotate, which can reset the traction bar 206. When the traction bar 206 resets, the gear a307 rotates in the opposite direction, releasing the clamping plate 208 from holding the mesh gauze 110, loosening the mesh gauze 110, and returning it to its initial position, preparing for the next rotation of the mesh gauze 110. This design allows the equipment to efficiently and accurately adjust the position of the mesh gauze 110 and achieve continuous cyclic operation.

[0073] As a further embodiment of the present invention, the inner wall of gear a307 is provided with a plurality of top grooves 308, the outer wall of lead screw a209 is provided with a plurality of connecting grooves 309, a push rod 310 is slidably connected in the connecting groove 309, a spring c311 is connected between the push rod 310 and the connecting groove 309, the top groove 308 is a hemispherical groove, and the end of the push rod 310 that cooperates with the top groove 308 is hemispherical;

[0074] By setting spring c311, spring c311 can apply a cooperating force to the top rod 310 and the top groove 308, and create a certain friction between the top rod 310 and the top groove 308. When gear a307 rotates under the action of rack 306, this friction can cause lead screw a209 to rotate. After the two clamping plates 208 move to their limit positions to clamp the mesh gauze 110, the rotation of lead screw a209 is restricted. As the traction bar 206 continues to move, the rotation of gear a307 can overcome the friction applied by spring c311, allowing the top groove 308 to disengage from the top rod 310. Gear a307 idles outside lead screw c302, avoiding jamming and ensuring smooth operation of the system. In addition, when the traction bar 206 moves back to its original position, the friction provided by spring c311 can promptly cause lead screw a209 to rotate in the opposite direction, loosening the mesh gauze 110 in time, preparing for the next rotation of the mesh gauze 110.

[0075] As a further embodiment of the present invention, the rotating component includes a motor 400 disposed at the bottom of the drying chamber 100, a gear b401 connected to the drive shaft of the motor 400, a transmission shaft 402 connected to the exhaust fan 102, and the bottom of the transmission shaft 402 passing through the drying chamber 100 and connected to a gear c403 that meshes with the gear b401.

[0076] By setting up motor 400, motor 400 can be turned on during application. The rotation of the drive shaft of motor 400 can cause the transmission shaft 402 to rotate through gears b401 and c403. The rotation of 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 the handicrafts to dry evenly and avoids the drying effect being affected by moisture retention.

[0077] As a further embodiment of the present invention, the rotating component also includes a gear d404 connected to the lead screw b300, a rotating shaft 405 connected to the bottom of the drying chamber 100, a gear e406 adapted to the gear d404 connected to the rotating shaft 405, the gear e406 being an incomplete gear, and a chain drive mechanism 407 provided between the rotating shaft 405 and one of the drive shafts 402.

[0078] By setting up a chain drive mechanism 407, when gear b401 rotates, the rotating shaft 405 can rotate through gear b401, gear c403, and the chain drive mechanism 407. When the rotating shaft 405 rotates to a preset angle, gear e406 meshes with gear d404, and gear d404 rotates with the lead screw b300. After the lead screw b300 rotates to a preset angle, the positioning bracket 111 moves downward to its limit position. When the lead screw b300 continues to rotate, it can rotate the connecting shaft 103 until gear e406 disengages from gear d404. This achieves 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 compartment 105 through the positioning component, and intermittently rotating the connecting shaft 103. During this process, the angle of the drying rack 104 is adjusted so that the handicrafts can receive uniform hot air coverage.

[0079] As a further embodiment of the present invention, the hot air conveying component includes a hot air blower 500 disposed on one side of the drying chamber 100, and a conveying pipe 501 connected to the air outlet of the hot air blower 500, and the drying pipe 106 is connected to the conveying pipe 501.

[0080] By setting up a hot air blower 500, the hot air blower 500 plays the role of continuously supplying hot air flow. Through the connection between the conveying pipe 501 and the drying pipe 106, the hot air flow can be evenly guided to the drying pipe 106 and further distributed to the top and bottom of the drying rack 104, ensuring the flow of hot air during the drying process.

[0081] As a further embodiment of the present invention, the hot air conveying component also includes a connection port 502 opened on one side of one of the drying pipes 106, a movable pipe 107 slidably connected to the connection port 502, a sealing pipe 503 slidably connected to the drying pipe 106 connected to the movable pipe 107 to cover the connection port 502, a follower frame 504 rotatably connected to the positioning bracket 111, and a portion of the movable pipe 107 extending to the top of the positioning bracket 111 being inserted into the follower frame 504.

[0082] By setting up a follower frame 504, when the positioning bracket 111 moves downward, the follower frame 504 can drive the movable tube 107 to move downward, so as to ensure that when the positioning bracket 111 moves downward to above the craft, the hot air blown out by the movable tube 107 can blow onto the mesh gauze 110, thereby achieving high-quality drying of the craft.

[0083] A method for drying resin handicrafts, applicable to any of the above-mentioned drying apparatuses for processing resin handicrafts, comprises the following steps:

[0084] Step 1: Depending on the shape and size of the resin crafts, selectively place them vertically or horizontally on the drying rack 104. Ensure the crafts are securely placed in the drying compartment 105, then prepare to start the equipment;

[0085] Step 2: Start the hot air conveying component. The hot air flow enters from the hot air blower 500 through the drying pipe 106, and passes through the movable pipe 107 and the fixed pipe 108, guiding the hot air flow to the bottom and top of the drying rack 104 to ensure that the hot air can evenly cover the surface of the craft.

[0086] Step 3: Driven by the rotating component, the connecting shaft 103 is rotated intermittently. Just before the connecting shaft 103 is about to rotate, the positioning bracket 111 moves downward to a preset position. The positioning component presses down on the mesh gauze 110, ensuring its deformation and covering of the craft, thereby fixing the craft and preventing displacement during rotation.

[0087] Step 4: Under the action of the rotating component, the drying rack 104 rotates with the rotation of the connecting shaft 103, the angle of the handicraft changes, and the hot air can fully cover all surfaces of the handicraft, including its recessed parts and obstructed areas.

[0088] Step 5: After each rotation to the preset angle, the connecting shaft 103 will pause for a period of time. At this time, the positioning bracket 111 will return to its original position and allow the mesh gauze 110 to leave the craft, allowing the humid air to escape.

[0089] Step Six: After the drying process is completed, use the motor 400 to adjust the position of the drying rack 104, remove the crafts from the drying compartment 105, and place new resin crafts on it.

[0090] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
