[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Please refer to Figures 1 to 6 , and now the wax mold production cleaning and air-drying device provided by the present invention will be described. The wax mold production cleaning and air-drying device includes a conveyor frame 1, a hook 2, a cleaning tank 111 and an air blowing pipe 3. A conveyor chain 121 that moves along the length direction of the conveyor frame 1 is installed on the conveyor frame 1; the number of hooks 2 is multiple, and the multiple hooks 2 are evenly spaced on the conveyor chain 121 and are used for installing wax molds; along the conveying direction of the conveyor chain 121, a cleaning section 11 and an air-drying section 12 are sequentially arranged on the conveyor frame 1. A cleaning tank 111 is installed below the cleaning section 11, and air blowing pipes 3 are installed on both sides of the air-drying section 12. An air outlet gap is provided on the side of the air blowing pipe 3 close to the air-drying section 12, and the length direction of the air outlet gap is inclined downward along the conveying direction of the conveyor chain 121.

[0032] The wax mold production cleaning and air-drying device provided by this embodiment, compared with the prior art, is provided with a conveying rack 1. A conveying chain 121 is installed on the conveying rack 1, and the conveying chain 121 moves along the length direction of the conveying rack 1. A hook 2 is connected to the conveying chain 121. The assembled wax mold can be installed on the hook 2 and move together with the movement of the conveying chain 121. The conveying rack 1 includes a cleaning section 11 and an air-drying section 12, and the air-drying section 12 is located behind the cleaning section 11. The cleaning section 11 is provided with a bent portion that bends downward. When the hook 2 passes through the bent portion, the wax mold on the hook 2 enters the inside of the cleaning tank 111 for cleaning. When the wax mold is output from the inside of the cleaning tank 111, it passes through the air-drying section 12. In this application, air blowing pipes 3 are provided on both sides of the air-drying section 12. An air outlet gap is provided on the side of the air blowing pipe 3 close to the air-drying section 12, and the air outlet gap is inclined. Thus, when the wax mold is being conveyed, the excess cleaning liquid on the wax mold can be blown dry from top to bottom, and the air blowing pipe 3 can be connected to the air outlet end of an external air compressor, reducing the use of fans. It can both air-dry the whole wax mold and reduce the use of the hair dryer 6, reducing the loss during the wax mold cleaning process, thereby reducing the production cost.

[0033] In some embodiments, the above air blowing pipe 3 can adopt a structure such as Figure 1 , Figure 2 shown. Referring together to Figure 1 , Figure 2 , the air blowing pipe 3 is arranged to be inclined downward along the conveying direction of the conveying chain 121. An air inlet pipe 31 is rotatably arranged inside the air blowing pipe 3. Two spiral blades 32 are hermetically connected to the outside of the air inlet pipe 31. The two spiral blades 32 are slidably connected to the inner wall of the air blowing pipe 3, and a ventilation flow channel is formed between the two spiral blades 32. The air blowing pipe 3 is communicated with the ventilation flow channel, and the ventilation flow channel and the air outlet gap form an air blowing port for conveying air to the wax mold. The air inlet pipe 31 is coaxially arranged with the air blowing pipe 3, and the air inlet pipe 31 is rotatably arranged inside the air blowing pipe 3. Two groups of spiral blades 32 are fixedly installed on the outside of the air inlet pipe 31. The two groups of spiral blades 32 are arranged at intervals along the axial direction of the air inlet pipe 31 to form a ventilation flow channel, and the outer sides of the spiral blades 32 are attached to the inner wall of the air blowing pipe 3. A plurality of air outlet holes are provided on the side wall of the air inlet pipe 31, and the plurality of air outlet holes are located inside the ventilation flow channel, so that most of the air flows out through the ventilation flow channel and is blown out through the air blowing port.

[0034] Specifically, in this embodiment, the conveying direction of the conveying chain 121 in the air-drying section 12 is defined as the first direction. When the air inlet pipe 31 drives the spiral blade 32 to rotate, the position of the air blowing port will displace along the length direction of the air blowing pipe 3. At the same time, the moving speed of the air blowing port along the first direction is the same as the conveying speed of the conveying chain 121 along the first direction. And when the wax mold moves to the side of the air blowing pipe 3, the air outlet formed by the ventilation flow channel and the air outlet gap is located on one side of the wax mold, so that the air outlet is always located on one side of the wax mold, and with the movement of the wax mold, the position of the air outlet relative to the wax mold changes from top to bottom. This can make the air act effectively on the wax mold, playing the role of energy conservation and consumption reduction.

[0035] Specifically, in this embodiment, the two spiral blades 32 are arranged at intervals along the circumferential direction of the air inlet pipe 31 to form a spiral ventilation flow channel, and both ends of the ventilation flow channel are of a closed structure to prevent air from flowing out.

[0036] In some embodiments, the above air blowing pipe 3 can adopt a structure as Figure 2 shown. Refer to Figure 2 , cover plates 33 are hermetically connected to both ends of the air blowing pipe 3. The air inlet pipe 31 is rotatably arranged between the two cover plates 33, and air outlet holes communicating with the ventilation flow channel are arranged on the side wall of the air inlet pipe 31. Both ends of the air inlet pipe 31 are air inlet ends. A sealing ring is arranged between the cover plate 33 and the inner wall of the air blowing pipe 3. Both ends of the air inlet pipe 31 are rotatably arranged on the two cover plates 33. And the air inlet pipe 31 is hermetically connected to the cover plate 33, and both ends of the air inlet pipe 31 penetrate through the two cover plates 33, so that both ends of the air inlet pipe 31 are communicated with the air outlet ends of the external air compressor, increasing the internal pressure of the air blowing pipe 3 and ensuring a stable air output volume inside the air blowing pipe 3.

[0037] In some embodiments, the above air blowing port can adopt a structure as Figure 1 、 Figure 2 and Figure 3 shown. Refer to Figure 1 、 Figure 2 and Figure 3The air outlet and the hook 2 move at the same speed along the conveying direction of the conveyor chain 121. The air outlet is located on the side of the air duct closest to the hook 2. A transmission assembly 4 is provided between the conveyor chain 121 and the air inlet pipe 31. The air outlet moves at the same speed as the hook 2 in the first direction. The rotational speed of the air inlet pipe 31 on the air duct 3 determines the air outlet's movement speed. The speed of the conveyor chain 121, in turn, determines the conveying speed of the wax model. By providing the transmission assembly 4 between the conveyor chain 121 and the air inlet pipe 31, the movement of the conveyor chain 121 drives the air inlet pipe 31 to rotate. This reduces the need for a separate drive source to rotate the air inlet pipe 31, saving equipment production costs. Furthermore, it maintains a stable transmission ratio between the conveyor chain 121 and the air inlet pipe 31. When the speed of the conveyor chain 121 increases or decreases, the rotational speed of the air inlet pipe 31 is adjusted synchronously, ensuring that the air outlet and the wax model move at the same speed in the first direction. This ensures that wind effectively acts on the wax model.

[0038] In some embodiments, the transmission assembly 4 may be configured as follows: Figure 3 、 Figure 4 See also Figure 3 、 Figure 4 The transmission assembly 4 includes a sprocket 41, a first synchronous wheel 42, a second synchronous wheel 43 and a synchronous belt 44. The sprocket 41 is rotatably mounted on the conveyor frame 1, and the conveyor chain 121 is meshed with the sprocket 41; the first synchronous wheel 42 is rotatably mounted on the conveyor frame 1 and is in transmission connection with the sprocket 41; there are two second synchronous wheels 43, which are fixedly mounted on the two intake pipes 31 respectively; the synchronous belt 44 is meshed with the first synchronous wheel 42 and the second synchronous wheel 43. A tooth groove is provided on the conveyor chain 121 for accommodating the teeth on the sprocket 41, so that the sprocket 41 can be driven to rotate during the movement of the conveyor chain 121. The sprocket 41 is rotatably connected to the first synchronous wheel 42, which is rotatably mounted on the top of the conveyor frame 1. The second synchronous wheel 43 is fixedly mounted at the end of the intake pipe 31. During operation, when the conveyor chain 121 moves on the conveyor frame 1, it will drive the sprocket 41 to rotate, the sprocket 41 will drive the first synchronous wheel 42 to rotate, and drive the two second synchronous wheels 43 to rotate through the synchronous belt 44, thereby realizing the transmission connection between the conveyor chain 121 and the air intake pipe 31.

[0039] Specifically, in this embodiment, a third synchronous wheel is rotatably mounted below the first synchronous wheel 42. The synchronous belt 44 is a double-sided toothed synchronous belt 44, and is wound between the first synchronous wheel 42, the second synchronous wheel 43, and the third synchronous wheel. This allows the synchronous belt 44 to be divided into two parts located in the air-drying section 12, thereby avoiding the transportation of the wax pattern.

[0040] Preferably, in this embodiment, two support wheels are rotatably arranged at the bottom of the conveying chain 121. The two support wheels are located on both sides of the sprocket 41 and are used to support the conveying chain 121 so that the conveying chain 121 remains engaged with the sprocket 41.

[0041] In some embodiments, the above-mentioned transmission assembly 4 can adopt the structure as Figure 4 shown. Refer to Figure 4 . A worm gear 45 is fixedly installed on the rotating shaft of the first synchronous wheel 42. A worm 46 that meshes with the worm gear 45 is rotatably arranged on the conveying frame 1. The worm 46 is in transmission connection with the sprocket 41. The rotating shaft of the first synchronous wheel 42 is rotatably arranged at the top of the air-drying section 12. A worm gear 45 is fixedly installed on the rotating shaft of the first synchronous wheel 42. The axis of the rotating shaft of the first synchronous wheel 42 is arranged parallel to the axis of the air inlet pipe 31 at an interval. The axis of the worm 46 is arranged parallel to the axis of the sprocket 41 at an interval. When the sprocket 41 rotates, it drives the worm 46 to rotate. The worm 46 drives the first synchronous wheel 42 to rotate through meshing with the worm gear 45. At the same time, the worm gear 45 and the worm 46 can achieve self-locking to prevent the outlet pipe from rotating and affecting the relative position between the air outlet and the hook 2 in the shutdown state.

[0042] In some embodiments, the above-mentioned transmission assembly 4 can adopt the structure as Figure 3 , Figure 4 shown. Refer to Figure 3 , Figure 4 together. A main shaft for installing the sprocket 41 is rotatably arranged on the conveying frame 1. A first gear 47 is fixedly installed on the main shaft. A second gear 48 that meshes with the first gear 47 is fixedly installed on the worm 46. The sprocket 41 is fixedly installed in the middle of the main shaft. First gears 47 are fixedly installed at both ends of the main shaft. Second gears 48 are fixedly installed at both ends of the worm 46. The main shaft and the worm 46 are arranged parallel to each other at an interval. The first gear 47 and the second gear 48 are meshed with each other. Thus, when the sprocket 41 rotates, it can drive the first synchronous wheel 42 to rotate. The structure is simple and compact, saving occupied space.

[0043] Specifically, in this embodiment, a transmission box is fixedly installed at the top of the air-drying section 12 on the conveying frame 1. The main shaft, the worm gear 45, the worm 46, the first gear 47 and the second gear 48 are all rotatably arranged inside the transmission box. It is convenient for modular installation and has an effective dust-proof effect.

[0044] In some embodiments, the above-mentioned air-drying section 12 can adopt the structure as Figure 5 , Figure 6 shown. Refer to Figure 5 , Figure 6, on both sides of the air-drying section 12, connecting arms 13 are inclined outward along the conveying direction of the conveying chain 121. A sliding arm 5 extending downward is installed on the connecting arm 13. The sliding arm 5 is slidably arranged on the connecting arm 13 along the length direction of the connecting arm 13. A hair dryer 6 for blowing air onto the top surface of the wax mold is installed at the bottom end of the sliding arm 5. The connecting arm 13 is arranged at an angle with the air-drying section 12, and the connecting arm 13 is inclined away from the air-drying section 12 along the moving direction of the conveying chain 121. The sliding arm 5 is slidably arranged on the connecting arm 13, and the hair dryer 6 is installed at the bottom end of the sliding arm 5. When the wax mold passes through the position of the connecting arm 13, the hair dryer 6 is used to blow air on the wax mold. And the moving speed of the sliding arm 5 in the first direction is the same as the moving speed of the wax mold in the first direction. When the wax mold moves along with the conveying chain 121, the hair dryer 6 moves relative to the wax mold in a horizontal direction and perpendicular to the first direction, so as to blow the cleaning liquid on the top of the wax mold to the side of the wax mold, and then further blow off and air-dry it through the blow pipe 3 at the rear. Through the setting of the hair dryer 6, the cleaning liquid on the top of the wax mold can be blown to both sides. The drying degree of the top of the wax mold is improved.

[0045] Specifically, in this embodiment, a sliding block is fixedly installed on the top of the sliding arm 5, and a long-shaped chute for accommodating the sliding block is arranged on the connecting arm 13. The length direction of the long-shaped chute is arranged along the length direction of the connecting arm 13. And a limiting plate for limiting the sliding block inside the long-shaped chute is also installed on the top of the sliding block.

[0046] In some embodiments, the above-mentioned hook 2 can adopt structures such as Figure 3 , Figure 5 as shown. See also Figure 3 , Figure 5, two push plates 21 arranged at an angle are fixedly installed on the hook 2, and the length direction of the push plate 21 is arranged at an angle with the moving direction of the conveying chain 121. The two sliding arms 5 form a guiding gap for accommodating the push plate 21, and an elastic member 7 for pushing the two sliding arms 5 to move towards the relatively close direction is further arranged on the connecting arm 13. The length direction of the push plate 21 is arranged at an angle with the length direction of the air-drying section 12. The connection part of the two push plates 21 is located on the hook 2. When the push plate 21 moves to the guiding gap, the connection part of the two push plates 21 preferentially enters the inside of the guiding gap. As the hook 2 moves, the distance between the two push plates 21 gradually becomes larger, thereby pushing the two sliding arms 5 to move outward. The hair dryers 6 located on the sliding arms 5 move outward synchronously. The connecting arm 13 is inclined outward along the first direction. Under the push of the push plate 21, the sliding arm � moves synchronously with the hook 2 along the first direction, and at the same time moves outward relative to the wax mold perpendicular to the first direction. When the hook 2 moves to the connecting arm 13 along with the conveying chain 121, during the subsequent movement, the automatic movement of the two blowers can be realized, so as to achieve the effect of automatically air-drying the top of the wax mold after the hook 2 passes through the two connecting arms 13.

[0047] Specifically, in this embodiment, the elastic member 7 is a spring. The two ends of the elastic member 7 respectively abut against the end of the long-shaped chute and the sliding block. When the push plate 21 disengages from the two sliding arms 5, the elastic member 7 can push the sliding arms 5 to move towards the relatively close direction to realize the reset of the hair dryer 6.

[0048] Preferably, in this embodiment, a buffer block is installed on the side of the sliding arm 5 away from the elastic member 7, which can play a buffering role during the reset process of the sliding arm 5 and improve the stability of the installation position of the hair dryer 6.

[0049] Specifically, in this embodiment, guide plates are further installed on the relatively close sides of the two sliding arms 5, and the guide plates on the two sliding arms 5 form a guiding gap.

[0050] In some embodiments, the above hair dryer 6 can adopt a structure such as Figure 5 , Figure 6 shown. Referring to Figure 5 , Figure 6 together, the position of the hair dryer 6 on the sliding arm 5 has the freedom to adjust along the pitch angle, and when the sliding arm 5 moves on the connecting arm 13, the hair dryer 6 rotates synchronously on the sliding arm 5. In the free state, the air outlet of the hair dryer 6 is arranged directly downward. When the sliding arm 5 moves away from the air-drying section 12, the air outlet of the hair dryer 6 swings outward, so that the cleaning liquid located on the top of the wax mold can be blown to both sides. Reduce the residue of the cleaning liquid on the top of the wax mold.

[0051] Specifically, in this embodiment, a mounting plate is rotatably provided at the bottom of the sliding arm 5. A first shaft body is fixedly installed on the mounting plate, and the axis of the first shaft body is arranged horizontally. A second shaft body is also rotatably provided on the sliding arm 5, and the axis of the second shaft body is arranged vertically. The first shaft body and the second shaft body are connected by bevel gear transmission. A third gear is fixedly installed on the first shaft body, and a rack is fixedly installed on the connecting arm 13. The length direction of the rack is arranged along the sliding direction of the sliding arm 5. When the sliding arm 5 moves on the connecting arm 13, the third gear will rotate accordingly and drive the second shaft body to rotate. When the first shaft body rotates, it will drive the first shaft body and the mounting plate to rotate through the transmission connection of the bevel gear, so as to realize the angle adjustment of the hair dryer 6.

[0052] In this embodiment, neither the movement of the hair dryer 6 nor the flipping of the angle requires an additional power source, and by moving the hair dryer 6 and flipping the angle, it is possible to dry the top of the wax mold by installing a single blower on each side of the air drying section 12.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
