Detailed Implementation

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0023] like Figures 1 to 6 As shown, this utility model provides a technical solution: The above description is merely an example of a wood toy raw material baking device with a low-temperature baking temperature circulation function, comprising a baking oven 1. The baking oven 1 is equipped with a rotating assembly 2 rotatably connected to the side walls at both ends of the baking oven 1. The bottom of the baking oven 1 is equipped with a heating assembly 3 communicating with the interior of the baking oven 1. The rotating assembly 2 includes a rotating shaft 22 disposed inside the baking oven 1 and an mounting sleeve 23 fixedly sleeved on the surface of the rotating shaft 22. The circumferential surface of the mounting sleeve 23 is provided with a plurality of fixing components 4 distributed in a rotationally symmetrical manner. The fixing components 4 include a fixing frame 41 connected to the mounting sleeve 23, an upper U-shaped fixing frame 43 disposed at the top of the frame inside the fixing frame 41, and a lower U-shaped fixing frame 44 disposed at the bottom of the frame inside the fixing frame 41. Wood fixing parts 47 are respectively disposed in the upper U-shaped fixing frame 43 and the lower U-shaped fixing frame 44.

[0024] Furthermore, in the above structure, the top of the baking oven 1 is provided with an exhaust pipe 11 that communicates with the interior of the baking oven 1, a control panel 12 is installed on the outer side wall of the tail end of the baking oven 1, and a door 13 is hinged to the body of the baking oven 1.

[0025] Furthermore, in the above structure, the two ends of the rotating shaft 22 are rotatably connected to the side wall of the baking oven 1, and the rotating assembly 2 is equipped with a motor 21 on the outer side wall of the front end of the baking oven 1, and the power output shaft of the motor 21 is connected to the rotating shaft 22.

[0026] It should be noted that the present invention should also include several temperature sensors installed inside the baking oven 1. The control panel 12 is electrically connected to the temperature sensors, the fan 32 and the heating rod 33 respectively to realize the temperature circulation function during the baking process.

[0027] This invention features an exhaust pipe 11 at the top of the baking oven 1 that can promptly expel moisture generated during the baking process, preventing internal humidity buildup from affecting the baking effect. The hinged door 13 of the oven body facilitates the insertion or removal of wood materials by workers. The rotating component 2 cooperates with the side walls at both ends of the baking oven 1. After the motor 21 installed on the outer side of the front end of the baking oven 1 is started, its power output shaft drives the rotating shaft 22 to rotate. The mounting sleeve 23 fixedly fitted on the surface of the rotating shaft 22 rotates synchronously. Several fixed components 4, which are circumferentially symmetrically distributed around the mounting sleeve 23, will carry the wood toy materials and rotate together, ensuring that all surfaces of the wood can be exposed to heat, thus solving the problem of uneven heating under traditional conveying methods.

[0028] In the fixing component 4, the fixing frame 41 provides installation support for the upper U-shaped fixing frame 43 and the lower U-shaped fixing frame 44. The wood fixing parts 47 inside both can firmly clamp the wood and prevent the wood from shifting during rotation. At the same time, several temperature sensors installed inside the baking oven 1 monitor the temperature inside the oven in real time and transmit the data to the control panel 12. The control panel 12 is electrically connected to the temperature sensors, the fan 32 and the heating rod 33 respectively. When the temperature deviates from the set range, the control panel 12 can adjust the heating power of the heating rod 33 and the wind speed of the fan 32. The hot air delivered by the heating component 3 through the uniform through-hole at the bottom of the baking oven 1 realizes the temperature circulation of low-temperature baking, ensuring that the wood is baked to a uniform degree and improving the structural stability of the wood.

[0029] As one of the preferred embodiments of this utility model, such as Figure 1 As shown, the heating assembly 3 includes a heating box 31 disposed at the bottom of the baking oven 1, a plurality of fans 32 disposed through the bottom side wall of the heating box 31, and a plurality of heating rods 33 disposed above the fans 32 and mounted on the heating box 31. The bottom side wall of the baking oven 1 is provided with a plurality of through holes for communicating with the heating box 31, and the through holes are evenly distributed on the bottom side wall of the baking oven 1.

[0030] In the heating assembly 3, the heating box 31 is fixed to the bottom of the baking oven 1, and the fan 32 passes through the bottom side wall of the heating box 31. After starting, it can draw outside air into the heating box 31. Several heating rods 33 above the fan 32 are installed on the heating box 31. After being powered on, they can quickly release heat to heat the drawn-in air. Several through holes are evenly distributed on the bottom side wall of the baking oven 1, which can evenly deliver the hot air in the heating box 31 to the interior of the baking oven 1, avoid local hot air accumulation, and ensure that all areas of the wood are heated evenly.

[0031] The heating element 3 and control panel 12 work together to achieve a temperature circulation function during the wood baking process. Specifically, the temperature sensor inside the baking oven 1 collects the internal temperature in real time and transmits the data synchronously to the control panel 12. Operators can preset multiple baking parameters on the control panel 12, such as setting a baking time of 25 minutes at 50℃, followed by 20 minutes at 45℃, forming a temperature circulation process. When the current temperature reaches the set duration, the control panel 12 automatically adjusts the heating power of the heating rod 33 to switch to the next target temperature, and simultaneously adjusts the fan speed of the fan 32 according to the target temperature to ensure that the hot air temperature matches the delivery efficiency. If the temperature sensor detects that the internal temperature deviates from the target value, it will immediately feed back to the control panel 12, which will then quickly fine-tune the power of the heating rod 33 and the speed of the fan 32 to ensure temperature stability, thereby achieving alternating cyclic baking at different temperatures.

[0032] As one of the preferred embodiments of this utility model, such as Figure 1 , Figures 3 to 6 As shown, the bottom of the fixed frame 41 is provided with an installation base plate 42 connected to the fixed frame 41. The installation base plate 42 is provided with an installation groove 421. The lower U-shaped fixed frame 44 is provided in the installation groove 421. A number of telescopic members 45 are evenly distributed between the lower U-shaped fixed frame 44 and the bottom of the installation groove 421.

[0033] Furthermore, in the above structure, the telescopic member 45 includes an outer sleeve 451 whose lower end is connected to the bottom of the mounting groove 421, a top rod 452 whose lower end is disposed inside the outer sleeve 451 and whose upper end is connected to the bottom surface of the lower U-shaped fixing frame 44, and a first spring 453 disposed inside the outer sleeve 451. The two ends of the first spring 453 are respectively connected to the bottom inner wall of the outer sleeve 451 and the bottom end of the top rod 452. A limiting groove 454 is provided on the inner wall of the outer sleeve 451, and a slider 455 that can slide in cooperation with the limiting groove 454 is provided on the circumferential surface of the top rod 452 near the bottom end.

[0034] The bottom of the fixed frame 41 provides a mounting base for the lower U-shaped fixed frame 44 via the mounting base plate 42. The mounting groove 421 on the mounting base plate 42 restricts the position of the lower U-shaped fixed frame 44 and prevents it from shifting. Several telescopic components 45 between the lower U-shaped fixed frame 44 and the bottom of the mounting groove 421 support the lower U-shaped fixed frame 44 and allow for elastic adjustment. Among the telescopic components 45, the outer sleeve 451 is fixed to the bottom of the mounting groove 421, the lower end of the push rod 452 is embedded in the outer sleeve 451 and the upper end is connected to the lower U-shaped fixed frame 44, the first spring 453 provides elastic support, and the limiting slide groove 454 on the inner wall of the outer sleeve 451 cooperates with the slider 455 of the push rod 452 to prevent the push rod 452 from disengaging from the outer sleeve 451 and ensure its vertical sliding.

[0035] If the width of the wood shrinks after baking, the first spring 453 will push the top rod 452 to slide upward, causing the lower U-shaped fixing frame 44 to move upward, so that the wood fixing piece 47 in the lower U-shaped fixing frame 44 always fits the wood, thereby adapting to the change in the width of the wood after baking and maintaining stable clamping.

[0036] As one of the preferred embodiments of this utility model, such as Figure 1 , Figures 3 to 6 As shown, symmetrical adjusting screws 46 are longitudinally arranged on the left and right sides of the fixed frame 41. The upper end of the adjusting screw 46 is placed above the top of the fixed frame 41, and the lower end of the adjusting screw 46 is rotatably connected to the top surface of the mounting base plate 42. The two ends of the upper U-shaped fixed frame 43 are threadedly connected to the adjusting screw 46.

[0037] The symmetrical adjusting screws 46 running longitudinally through the left and right sides of the fixed frame 41 extend above the top of the fixed frame 41, making it convenient for operators to manually rotate them. The lower end is rotatably connected to the top surface of the mounting base plate 42 to ensure the stability of the screws when they rotate. The two ends of the upper U-shaped fixed frame 43 are threadedly connected to the adjusting screws 46, forming a screw drive structure.

[0038] When faced with wood of different initial widths before baking, the operator rotates the adjusting screw 46. Under the action of the threaded engagement, the upper U-shaped fixing frame 43 moves up and down along the adjusting screw 46, thereby changing the distance between the upper U-shaped fixing frame 43 and the lower U-shaped fixing frame 44. According to the actual initial width of the wood, the distance is adjusted to the appropriate size, so that the wood fixing parts 47 inside the two can stably clamp the wood, thus achieving the adaptation for wood of different initial widths.

[0039] As one of the preferred embodiments of this utility model, such as Figure 1 , Figures 3 to 6As shown, the wood fixing component 47 includes a bidirectional screw 471 horizontally penetrating the front and rear side walls of the upper U-shaped fixing frame 43 and the lower U-shaped fixing frame 44, two adjusting plates 472 and two fixing plates 473 respectively disposed within the upper U-shaped fixing frame 43 and the lower U-shaped fixing frame 44, with the fixing plates 473 disposed between the adjusting plates 472. The adjusting plates 472 and the fixing plates 473 are mirror-symmetrical about the central axis of the width direction of the fixing frame 41. The bidirectional screw 471 is symmetrically disposed at both ends of the upper U-shaped fixing frame 43 and the lower U-shaped fixing frame 44. The two ends of the adjusting plates 472 are threadedly connected to one end of the bidirectional screw 471. The front and rear side walls of the mounting base plate 42 are provided with through grooves 422 at positions corresponding to the bidirectional screw 471 for vertical movement of the bidirectional screw 471.

[0040] Furthermore, in the above structure, a plurality of evenly distributed second springs 475 are provided between the adjusting plate 472 and the fixing plate 473. The two ends of the second springs 475 are respectively connected to the adjusting plate 472 and the fixing plate 473. A plurality of evenly distributed fixing teeth 474 are provided on the inner surface of the fixing plate 473.

[0041] In the wood fastener 47, the bidirectional lead screw 471 horizontally penetrates the front and rear side walls of the upper U-shaped fixing frame 43 and the lower U-shaped fixing frame 44 respectively, and is symmetrically arranged at both ends in the two U-shaped fixing frames; the two adjusting plates 472 and the two fixing plates 473 of the upper U-shaped fixing frame 43 and the lower U-shaped fixing frame 44 are mirror-symmetrical about the central axis of the width direction of the fixing frame 41. The fixing plate 473 is located between the adjusting plates 472. The two ends of the adjusting plate 472 are threaded to one end of the bidirectional lead screw 471 respectively. Several second springs 475 between the adjusting plate 472 and the fixing plate 473 provide elastic support. The fixing teeth 474 on the inner side of the fixing plate 473 enhance the contact friction with the wood.

[0042] When adapting to changes in the initial thickness of the wood before baking, rotating the bidirectional lead screw 471 causes the two adjusting plates 472 to move symmetrically closer or further apart due to the opposite thread directions at both ends of the bidirectional lead screw 471. This adjusts the distance between the two fixing plates 473 to accommodate woods of different initial thicknesses. If the wood shrinks or slightly deforms after baking, the second spring 475 will elastically extend and retract, pushing the fixing plates 473 to remain in contact with the wood surface and maintain clamping force. When fixing the wood, the fixing teeth 474 embed into the wood surface to prevent slippage, while the elastic pressure of the second spring 475 continuously clamps the wood. This dual action ensures the wood remains stable during rotational baking, preventing displacement that could affect the uniformity of baking.

[0043] In choosing the implementation method, it should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
