Description

Technical Field

[0001] The utility model relates to the field of Christmas tree processing, in particular to a velvet spraying system for Christmas trees. Background Art

[0002] In Europe and the United States, Christmas trees are widely used as decorations during Christmas celebrations. Spraying Christmas trees to create a snowy effect can enhance the festive atmosphere. Currently, most Christmas tree velvet is sprayed manually, and then the trees are left to air dry or placed in a drying oven for baking. Natural drying is inefficient, and undried trees cannot be stored or boxed, which takes up a large area of the factory floor and affects the efficiency of the spraying process. During baking, trees are often transported on carts, requiring workers to load them onto the carts. This is inefficient, and the carts lack fixed tracks, causing them to wobble during movement, causing undried spray to fall, affecting the "snowflake" effect. Furthermore, because heat is concentrated in traditional baking ovens, the position of the tree remains constant during baking. This can lead to uneven heating, which affects the baking effect, resulting in low drying efficiency and high energy consumption. Utility Model Content

[0003] Based on this, the purpose of the present invention is to overcome the defects or shortcomings of the prior art and provide a spraying system for a Christmas tree.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a velvet spraying system for a Christmas tree, comprising:

[0005] A spray room, having an entrance and an exit, and at least one velvet spraying device installed in the spray room;

[0006] The curing room comprises a wall, a heating structure and an air duct. The wall is provided with a curing room entrance and a curing room exit in the width direction. The inner side of the wall is provided with a heat-insulating layer. The heating structure is provided on a side of the curing room body away from the curing room entrance. The air duct is provided on the top and side of the wall and is connected to the heating structure. The wall is provided with a plurality of air inlets, which are connected to the air duct to transport the high temperature generated by the heating structure into the curing room. The air duct is provided with a fan valve for adjusting the air volume of the air inlet.

[0007] The conveying track extends sequentially through the spraying room entrance, the spraying room exit, the baking room entrance and the baking room exit to the outside of the baking room exit;

[0008] The conveying structure is provided in plurality and moves along the conveying track. The conveying structure is provided with a fixing structure for fixing the Christmas tree.

[0009] Compared to existing technologies, the Christmas tree velvet spraying system provided by the present invention utilizes rails to transport Christmas trees between the spraying and drying rooms, making the transportation process more stable and reliable, with high efficiency, and reducing the risk of sprayed velvet falling from the trees due to shaking during manual handling. Furthermore, the present Christmas tree velvet spraying system uses a fan to transport the high temperature generated by the heating structure into the air ducts on the top and sides of the wall, distributing the hot air onto the inner walls of the drying room, evenly drying the sprayed velvet on the Christmas tree, improving the drying effect, and thereby shortening the drying time of the tree, achieving energy-saving effects.

[0010] In one embodiment, the conveyor track includes a curing room floor track located within the curing room, the curing room floor track being in the shape of a bow; the curing room floor track includes a first floor track, the first floor track being parallel to and adjacent to a side surface of the wall and extending along the side surface to the curing room entrance; the air duct includes a first side air duct, the first side air duct being located on the outside or inside of the side surface of the wall; the side surface of the wall or the first side air duct, adjacent to the first floor track, having a plurality of side air inlets formed along the direction of travel of the first floor track, the side air inlets being slightly higher than the first floor track, such that air from the side air inlets flows from the bottom of the Christmas tree to the top of the Christmas tree. This arrangement preheats and dries the Christmas tree from the bottom up, preventing air from the side air inlets from directly contacting the upper surfaces of the branches and leaves of the newly sprayed Christmas tree, which would affect the shape and distribution of the sprayed Christmas tree and, consequently, the spraying effect of the Christmas tree.

[0011] In one embodiment, the baking room rail further comprises an intermediate rail and a second rail, the ends of the intermediate rail being connected to the first rail and the second rail respectively, the second rail being parallel to and adjacent to the side of the wall away from the first rail, and extending along the side to the outside of the baking room exit; a plurality of top air inlets are provided in the area of the top of the wall corresponding to the intermediate rail, the angle between the air outlet direction of the top air inlets and the running direction of the corresponding intermediate rail being greater than or equal to 90°; the air duct comprises a top air duct, which is provided on the outside of the top of the wall and connected to the top air inlet. Through this setting, the high temperature generated by the heating structure is evenly transported into the baking room and directly contacts the upper surface of the preheated Christmas tree, further increasing the temperature of the Christmas tree and the air flow rate on the surface of the Christmas tree, thereby improving the drying effect of the Christmas tree spray.

[0012] In one embodiment, a first partition is provided between the first and middle floor rails, and a second partition is provided between the middle and second floor rails. The first and second partitions are provided with an insulation layer and a second side air duct on the side closest to the middle floor rail. The second side air duct is provided with a plurality of air outlets, with the air outlet direction of the air outlets forming an angle of less than or equal to 90° with the direction of travel of the middle floor rail. This arrangement improves the uniformity of heat distribution between the first and second partitions within the drying room, reducing heat loss. Furthermore, the top and side air outlets increase the area of the Christmas tree directly exposed to the hot air, thereby enhancing the drying effect of the sprayed Christmas tree.

[0013] In one embodiment, a side of the wall near the second floor rail has several cold air inlets formed along the direction of travel of the second floor rail, and a cold air duct is provided on the exterior thereof, communicating with the cold air inlets. A fan is installed within the cold air duct, with the fan's outlet communicating with the cold air inlet and its inlet communicating with the exterior of the drying room, and a filter is provided at the inlet. This arrangement allows for high-volume cold air drying of Christmas trees that are nearing or already dried, lowering the temperature of the trees and allowing workers to directly unload them after they reach the unloading area. Furthermore, by increasing the air velocity over the surface of the trees, the air removes evaporated water vapor, thereby accelerating the drying process.

[0014] In one embodiment, the angle between the outlet direction of the side air inlet and the forward direction of the first ground rail is less than or equal to 90°. The wind speed or air volume of the side air inlet is less than the wind speed or air volume of the top air inlet and air outlet, and the wind speed or air volume of the cold air inlet is greater than the wind speed or air volume of the top air inlet and air outlet. With this configuration, as the sprayed velvet on the Christmas tree surface dries, the air flow velocity on the surface of the Christmas tree gradually increases, thereby improving the drying efficiency of the sprayed velvet on the Christmas tree and preventing excessive wind speed upon the tree entering the drying room from affecting the position and uniformity of the sprayed velvet on the Christmas tree.

[0015] In one embodiment, the intermediate rail includes several transverse rails, with a third partition disposed between them. On either side of the third partition are an insulation layer and a second side air duct. The second side air duct has several air outlets extending along the direction of travel of the transverse rails and the height of the Christmas tree. The air outlets on either side of the transverse rails are angled toward the direction of travel of the transverse rails, forming an obtuse angle with the direction of travel, so that the air outlets from the two air outlets converge at an angle. This arrangement increases the area and duration of direct wind exposure on the Christmas tree on the transverse rails, reduces temperature differences between different parts of the Christmas tree, and improves the uniformity of the Christmas tree's spray drying, thereby enhancing the drying effect, shortening drying time, and achieving energy savings.

[0016] In one embodiment, the drying rail further comprises a steering structure, comprising a fixed seat and a lifting device. A conveyor belt is disposed on the surface of the fixed seat. The lifting device is movably disposed within the fixed seat and rises and falls within a range of heights above and below the upper surface of the fixed seat. The lifting device is provided with rollers. The movement directions of the conveyor belt and the rollers are respectively consistent with the movement directions of the drying rail entering the steering device and exiting the steering structure. The upper surface of the conveyor belt is flush with the transport surface of the drying rail entering the steering device, and the upper surface of the roller can be flush with the transport surface of the drying rail exiting the steering structure. This configuration changes the forward surface of the Christmas tree on different transverse rails. Simultaneously, due to the relative change in the flow direction of the hot air on different transverse rails, the direct windward surface of the Christmas tree and the hot air changes, thereby improving the uniformity of the Christmas tree's spray drying, shortening the drying time, and achieving energy-saving effects.

[0017] In one embodiment, the heating structure includes a housing, a heating device, and a fan disposed within the housing. The housing is provided with an access door. A dehumidification fan and a temperature and humidity sensor are disposed between the first and second partitions. This arrangement reduces humidity within the drying room, promoting evaporation of moisture from the Christmas tree fleece, thereby shortening drying time.

[0018] In one embodiment, the drying room rails also include a third rail and a reversing mechanism. The ends of the third rail are connected to the middle rail and the second rail, respectively. A reversing mechanism is provided at the junction of the third rail, the middle rail, and the second rail, which controls the conveying mechanism's movement between the second rail and the third rail. This configuration allows for flexible control of the drying time of different Christmas trees in the drying room, allowing them to be dried simultaneously. This allows longer-lasting Christmas trees to remain on the rails or travel longer without affecting the drying of other trees.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] See also Figure 1 The embodiment of the present application provides a spraying system for Christmas trees, including a spraying room 10 and a baking room 20. A conveying track 30 is provided between the spraying room 10 and the baking room 20. A plurality of conveying structures 31 are provided on the conveying track 30. The conveying structure 31 is provided with a fixing structure for fixing the Christmas tree for transporting the Christmas tree.

[0031] The spray room 10 includes a spray room body 11 and a spray room ground rail 12. The spray room body 11 is provided with a spray room entrance and a spray room exit for Christmas trees to enter and exit the spray room 11. At least one spraying device is provided in the spray room body 11. The spray room ground rail 12 extends outward from the entrance of the spray room 11 to form a loading area, and is connected to the conveying rail 30 at the exit. The spray room ground rail 12 runs in the direction from the entrance of the spray room 10 to the exit of the spray room 10. The conveying structure 31 is transferred to the baking room 20 along the spray room ground rail 12 and the conveying rail 30.

[0032] The curing barn 20 includes a main body 21 and a curing room floor rail 22. The main body 21 is provided with a curing room entrance and a curing room exit. The curing room floor rail 22 is arched and connects to the conveyor rail 30 at the curing room entrance. It extends from the curing room exit to the outside of the curing room 20, forming a loading area. The curing room floor rail 22 runs from the curing room entrance to the curing room exit, and the conveyor structure 31 moves along the conveyor rail 30 and curing room floor rail 22 to the loading area. Preferably, the curing room main body 20 is rectangular in shape, with the curing room entrance and exit located on the same side, at opposite ends of the width of the curing room main body 20. The shapes of the curing room entrance and exit complement the shapes of the rail and the Christmas tree to minimize heat loss within the curing room.

[0033] Furthermore, baffles are provided on the outside of the conveying track 30, the baking room track 22, and the spraying room track 12 to limit the position of the conveying structure 31 and prevent it from sliding off the side of the track.

[0034] Specifically, the curing barn body 21 includes a wall 211, the inner side of which is provided with an insulation layer. The curing barn 20 also includes a heating structure 23 and an air duct 24. The heating structure 23 is located on a side of the curing barn body 21 away from the curing barn entrance and exit. The heating structure 23 includes a housing 231, a heating device 232 disposed within the housing 231, and a fan 233. The heating device 232 can be a heating furnace, a burner, or the like. The air duct 24 is provided with a fan valve for adjusting the air volume. The heating device 232 is connected to the air duct 24, and a vent is provided between the heating device 232 and the air duct 24. Furthermore, the housing 231 serves as a combustion chamber, which is equipped with an access door 234 to facilitate maintenance of the heating device 232.

[0035] In some embodiments, the air duct 24 is fixed on the inner side of the wall 211 of the baking room body 21, and a plurality of air inlets 213 are opened on the side of the air duct 24 close to the baking room rail 22 to transport the high temperature generated by the heating structure 23 to the inner wall of the baking room body 21, thereby drying the sprayed wool on the Christmas tree more evenly and improving the drying effect.

[0036] In some embodiments, an air inlet 213 is opened on the wall 211, and the air duct 24 is fixed on the outside of the wall 211 of the baking room body 21 and is connected to the air inlet 213 of the wall 211. The air duct 24 includes a first side air duct 241 and a top air duct 242, which transports the high temperature generated by the heating structure 23 to the inner wall of the baking room body 21, thereby drying the sprayed wool on the Christmas tree more evenly and improving the drying effect.

[0037] Specifically, the baking room entrance is arranged at the end of the baking room body 21 in the width direction, and the baking room ground rail 22 includes a first ground rail 221 connected to the conveying rail 30, several intermediate ground rails 222 connected to the first ground rail 221, and a second ground rail 223 connecting the intermediate ground rail and the lower piece area. The first ground rail 221 is parallel to the length direction of the baking room body 21 and is adjacent to one of the walls in the length direction of the baking room body 21. The first side air duct 241 is arranged on the outside of the wall adjacent to the first ground rail 221. Several side air inlets 213a are opened at the connection position between the wall and the first side air duct 241, and the side air inlet 213a is provided with an air guide structure protruding from the inside of the wall. The angle between the air outlet direction of the air guide structure and the running direction of the first ground rail 221 is less than or equal to 90°, so that the air outlet of the first side air duct 241 does not directly contact the undried Christmas tree when heating the Christmas tree, thereby preventing the hot air from blowing off the sprayed fluff of the Christmas tree or causing the sprayed fluff to shift in position. Preferably, the heating structure 23 is located on a side of the curing barn 20 away from the curing barn entrance. The spacing between the plurality of side air inlets 213a decreases gradually along the direction from the curing barn entrance to the heating structure 23, and the air outlet angle of the side air inlets 213a gradually shifts from parallel to the Christmas tree to perpendicular to the Christmas tree. In some embodiments, the angle between the air outlet direction of the side air inlets 213a and the forward direction of the first ground rail is 20-70 degrees. By increasing the distance between the air outlet and the Christmas tree, the wind speed at the Christmas tree is reduced, reducing the amount of hot air that blows down the spray pile and helping to reduce heat loss from the curing barn entrance.

[0038] Furthermore, the height of the first side air duct 241 is slightly higher than the height of the first ground rail 221, and the height of the first side air duct 241 is close to or slightly lower than the height of the base of the branches of the Christmas tree transported on the first ground rail 221. This allows the air from the side air inlet 213a to flow from the base of the Christmas tree to the top of the Christmas tree, thereby preheating the entire Christmas tree. This heating method helps reduce direct contact between the airflow and the sprayed down on the upper surfaces of the Christmas tree branches and leaves, avoiding affecting the sprayed down effect, thereby heating the sprayed down on the Christmas tree. The first side air duct 241 is equipped with a side fan valve 241a, which controls the airflow or wind speed of the first side air duct 241 to be lower than the airflow or wind speed of the first top air duct 242.

[0039] The top air duct 242 is arranged at the top of the baking room main body 21 and is parallel to the middle ground rail 222. A plurality of top air inlets 213b are opened between the top air duct 242 and the baking room main body 21. The plurality of top air inlets 213b are arranged at intervals along the running direction of the middle guide rail 222, and the air inlet direction of the top air inlet 213b is vertically downward, or the air inlet direction of the top air inlet 213b is inclined downward. The top air inlet 213b is provided with an air guide structure protruding from the inner side of the wall. The opening of the air guide structure is arranged toward the direction of the Christmas tree close to the top air inlet 213b, that is, the angle between the air outlet direction of the air guide structure and the forward direction of the Christmas tree is greater than or equal to 90°, so that the hot air from the top air inlet 213b and the Christmas tree close to the top air inlet 213b can quickly convect, further increasing the temperature of the Christmas tree, and by increasing the flow rate of air on the surface of the Christmas tree, the evaporated water vapor is taken away, thereby achieving the drying of the sprayed wool on the Christmas tree. Preferably, the middle ground rail includes a plurality of transverse ground rails, the plurality of top air ducts 242 correspond to the plurality of transverse ground rails respectively, and the plurality of top air ducts 242 are in communication with the heating structure 23 .

[0040] Furthermore, a dehumidification fan 25 is provided on the wall of the baking room 20 away from the heating structure 23. The dehumidification fan 25 discharges the high-humidity hot air in the baking room 20 out of the baking room 20. A fresh air inlet is provided in the heating structure 23, and a filtering device is provided at the fresh air inlet. The fresh air outside the baking room 20 is filtered by the filtering device of the fresh air inlet and then enters the heating structure 23. Then, after being heated by the heating structure 23, it enters the baking room 20 through the side air duct 241 and the top air duct 242 to circulate the hot air.

[0041] Furthermore, a first partition 214 is provided between the first floor rail 221 and the middle floor rail, and a second partition 215 is provided between the middle floor rail 222 and the second floor rail 223. The first partition 214 and the second partition 215 are provided with an insulation layer and a second side air duct 243, respectively, on the side facing the middle floor rail 222. The second side air duct 243 is connected to the top air duct 242 or the heating structure 23. The second side air duct 243 is provided with a plurality of air outlet nozzles 243a on the side facing the middle floor rail. The plurality of air outlet nozzles 243a are spaced apart along the height of the Christmas tree and / or the direction of travel of the middle floor rail 222. The air outlet nozzles 243a are arranged to discharge air perpendicular to the middle floor rail 222, or are inclined toward the forward direction of the Christmas tree, i.e., the angle between the air outlet direction of the air outlet nozzles 243a and the direction of travel of the adjacent middle floor rail is less than or equal to 90 degrees, thereby increasing the area directly exposed to the wind or the time directly exposed to the wind on the Christmas tree.

[0042] In some embodiments, the middle ground rail 222 includes a plurality of transverse ground rails, a middle partition 216 is provided between the plurality of transverse ground rails, a second side air channel 243 is provided on both sides of the middle partition 216, and a plurality of air outlet nozzles 243a are provided on the second side air channel 243, and the plurality of air outlet nozzles 243a are spaced apart along the height direction of the Christmas tree and / or the running direction of the middle ground rail 222. Preferably, refer to Figure 4-5 The air outlet direction of the air outlet nozzle 243a is perpendicular to the middle ground rail 222, or the air outlet direction of the air outlet nozzle 243a is inclined toward the forward direction of the Christmas tree, so that the direct wind-exposed surface of the Christmas tree is increased and is always in a directly wind-exposed state.

[0043] Preferably, see Figure 5 The air outlet directions of the air outlet nozzles 243a on both sides of the transverse ground rail are inclined toward the forward direction of the Christmas tree, forming an acute angle with the running direction of the middle ground rail 222, so that the air outlets on both sides form an angle intersection. Specifically, on the first transverse ground rail, the first side a of the Christmas tree is the front side, and the second side b is the rear side. At this time, the air outlet of the top air duct 242 is perpendicular to the top of the Christmas tree, or contacts the first side a of the Christmas tree, and the air outlet of the second side air duct 243 contacts the second side b of the Christmas tree, thereby increasing the direct wind-exposed surface of the Christmas tree and avoiding the air outlet of the second side air duct 243 only contacting the left and right sides of the Christmas tree without contacting the rear side. When the Christmas tree runs to the second transverse ground rail, the first side a of the Christmas tree is the rear side, and the second side b is the front side. The air outlet of the top air duct 242 is perpendicular to the top of the Christmas tree, or contacts the second side b of the Christmas tree, and the air outlet of the second side air duct 243 contacts the first side a of the Christmas tree, thereby increasing the direct wind-exposed surface of the Christmas tree. When the Christmas tree is located on different transverse ground rails, the direct wind-exposed surfaces of the Christmas tree to the second side air duct 243 and the top air duct 242 are constantly changing, so that during the running of the Christmas tree on the middle ground rail 222, the entire Christmas tree is exposed to wind and heat more evenly, thereby improving the drying effect of the spray pile. Preferably, the angle between the air outlet direction of the air outlet nozzle 243a and the running direction of the adjacent middle ground rail is 30-70°.

[0044] Furthermore, the second ground rail 223 is adjacent to the wall of the drying room body 21, which is located farther from the first ground rail 221. A cold air duct 244 is provided on the exterior of the wall. Several cold air inlets 217 are provided at the junction of the cold air duct 244 and the wall 211. A fan is provided within the cold air duct 244. The fan's outlet communicates with the cold air inlet 217, while the fan's inlet communicates with the outside world. A filter is provided to filter dust and other impurities from the air. The wind speed of the cold air inlet 217 is greater than the speed of the hot air from the first ground rail 221 and the middle ground rail 222. The air flowing through the surface of the Christmas tree removes evaporated water vapor, thereby accelerating the drying process. Furthermore, the cold air convects with the hot air on the surface of the Christmas tree, cooling the tree and allowing workers to directly contact the tree as it is being transported to the unloading area for unloading. Preferably, the cold air inlets 217 are spaced apart along the height of the Christmas tree and / or along the direction of travel of the second ground rail.

[0045] Furthermore, the conveying structure 31 is provided with a rotating structure for controlling the rotation of the Christmas tree. The rotating structure is a rotating structure in the prior art. When the Christmas tree runs along the second ground rail, the rotating structure controls the rotation of the Christmas tree to achieve uniform drying and uniform cooling of the Christmas tree.

[0046] The baking room 20 is also provided with a temperature and humidity sensor (not shown in the figure). The temperature and humidity sensor is set in the area between the first partition 214 and the second partition 215. The temperature and humidity sensor controls the start and stop of the heating and dehumidification fans through data processing software and hardware, and can independently control the temperature and humidity of the baking room and the operation and residence time of the conveying structure.

[0047] Furthermore, the baking room rail 22 is bent to form a bow shape, and each bending portion of the baking room rail 22 is provided with a steering structure 26, see Figure 6-8The bending part includes a first section of straight rail A and a second section of straight rail B. The transport surface of the second section of straight rail B is higher than the transport surface of the first section of straight rail A. The turning structure 26 is arranged on the second section of straight rail B and is located in front of the first section of straight rail A. The conveying structure 31 enters the turning structure 26 from the first section of straight rail A and is transported to the second section of straight rail B through the turning structure 26. Specifically, the steering structure 26 includes a fixed seat 261 and a lifting device 262. The fixed seat 261 is provided with a conveyor belt 263 whose running direction is consistent with the running direction of the first section of straight rail A, and the conveyor belt 263 is flush with the conveying surface of the first section of straight rail A. The lifting device 262 rises and falls between its first position and second position. The lifting device 262 is provided with a roller 264 which is consistent with the running direction of the second section of straight rail B. When the lifting device 262 is in its first position, the lifting device 262 protrudes from the fixed seat 261 and is flush with the transport surface of the second section of straight rail B, and the upper surface of the roller 264 in the first position is flush with the transport surface of the second section of straight rail B, thereby transporting the conveying structure 31 to the second section of straight rail B. The upper surface of the lifting device 262 in the second position is lower than the upper surface of the conveyor belt 263, so that the conveying structure 31 can be transported from the first section of straight rail A to the steering structure 26. The steering structure 26 is further provided with a position sensor or a pressure sensor for detecting whether the conveying structure 31 completely enters or completely leaves the steering structure 26 .

[0048] Furthermore, the drying room rail 22 also includes a third rail 224 and a reversing structure 225. The ends of the third rail 224 are respectively connected to the middle rail 222 and the second rail 223. The reversing structure 225 is provided at the connection between the third rail 224 and the middle rail 222. By adjusting the reversing structure 225, the trajectory of the Christmas tree in the drying room rail 22 can be controlled, thereby adjusting the drying time of the Christmas tree. When the Christmas tree is large and requires a longer drying time, the trajectory of the Christmas tree in the drying room is the first rail 221, the middle rail 222, the third rail 224, and the second rail 223. When the Christmas tree requires a shorter drying time, the trajectory of the Christmas tree in the drying room is the first rail 221, the middle rail 222, the third rail 224, and the second rail 223.

[0049] In some embodiments, a detection device is provided at the reversing structure 225 for detecting the dryness of the sprayed down on the Christmas tree. When the sprayed down on the Christmas tree is dry or nearly dry, the reversing structure 225 controls the Christmas tree to move along the middle ground rail 222 to the second ground rail 223. When the sprayed down on the Christmas tree is dry, the reversing structure 225 controls the Christmas tree to move along the third ground rail 224 and / or stay on the third ground rail 225. When the sprayed down on the Christmas tree is dry or nearly dry, the reversing structure 225 controls the Christmas tree to move along the third ground rail 224 to the second ground rail 223. In some embodiments, the detection device is a humidity sensor that determines the dryness of the Christmas tree by measuring the humidity on the surface of the Christmas tree.

[0050] Furthermore, a plurality of UV lamps 27 are provided on the top of the baking room 20 for curing the glue on the Christmas tree, thereby accelerating the drying of the sprayed fleece on the Christmas tree.

[0051] In some embodiments, a fire hose is installed on the outer wall of the spray booth 10. The other end of the fire hose passes through the top wall of the spray booth and is connected to a fire sprinkler. When an open fire occurs, the fire hose and the fire sprinkler can be used to extinguish the fire, thereby improving safety. A flame detector is installed on the inner top wall of the spray booth 10. The flame detector can detect flames and issue an alarm.

[0052] Compared with the existing technology, the beneficial effects of the technical solution of the utility model are as follows:

[0053] (1) The relative change of the flow direction of the hot air on different ground rails causes the direct windward surface of the Christmas tree to change, which reduces the temperature difference between different parts of the Christmas tree during the drying process, improves the uniformity, thereby improving the drying effect, shortening the drying time, and achieving energy-saving effects.

[0054] (2) By adjusting the temperature and wind speed of the airflow on different ground rails, the direct wind exposure of the Christmas tree when it first enters the drying room is reduced, thereby avoiding affecting the spraying effect of the Christmas tree and reducing the loss of heat energy from the entrance of the drying room. After the Christmas tree is preheated and the spraying is dried for a certain period of time, the direct wind exposure surface of the Christmas tree is increased to improve the drying efficiency of the Christmas tree. When the Christmas tree is about to be dried, a large amount of cold air is used to dry the Christmas tree to reduce the temperature of the Christmas tree so that the workers can directly unload the Christmas tree after the Christmas tree reaches the unloading area. At the same time, by increasing the air flow rate on the surface of the Christmas tree, the evaporated water vapor is taken away, thereby accelerating the drying process of the Christmas tree.

[0055] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
