Description

Technical Field

[0001] This utility model relates to the field of solar screen baking technology, and in particular to a baking device for solar screen production with a protective structure. Background Technology

[0002] Solar-powered screen printing typically consists of a screen frame and a screen mesh. The screen frame holds the screen mesh in place, ensuring its stability during the printing process. The screen mesh, in turn, supports and transfers the printing ink.

[0003] During the production process, solar screen panels need to be baked. When general baking equipment bakes multiple screen panels simultaneously, the statically arranged screen panels in the baking equipment will be heated differently depending on their position. Screen panels that are close to the heat source may be over-baked during static baking, which can damage the screen panels. Utility Model Content

[0004] This utility model discloses a baking device for solar screen production with a protective structure, which aims to solve the technical problem that multiple screens are heated unevenly during the baking process, and that screens close to the heat source may be over-baked during static baking, causing damage to the screens.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A baking device for producing solar screens with a protective structure includes a baking chamber and a door movably connected to the outer wall of one side of the baking chamber. The baking chamber is also equipped with a placement mechanism, a central air guide mechanism located in the middle of the placement mechanism, side air guide mechanisms located on both sides of the placement mechanism, and a baking machine installed on the side air guide mechanisms.

[0007] The installation mechanism includes a square support frame, multiple protective frames movably connected to the square support frame, multiple through slots penetrating the protective frames, a load-bearing block fixedly connected to the outer wall of the bottom end of the protective frame, a connecting seat fixedly connected to the center position of the bottom end of the square support frame, a second branch shaft fixed to the connecting seat, and a motor connected to one end of the second branch shaft.

[0008] The inner walls of the opposite sides of the square support frame are provided with multiple connection holes, and the outer walls of the opposite sides of each protective frame are fixedly connected with connecting rods, and the multiple connecting rods are respectively movably arranged in the connection holes.

[0009] The bottom inner wall of the baking chamber is fixedly connected to a side bracket, and a second support shaft passes through the side bracket. The motor is fixedly connected to one side outer wall of the side bracket.

[0010] The structure incorporates a mounting mechanism in which a motor drives a square support frame to reciprocate, causing the two sides of the frame to swing up and down. During this swing, the multiple protective frames, after being staggered, reduce the obstruction between adjacent frames, allowing the internal mesh to better contact with the hot air. Simultaneously, a certain amount of hot air flow is generated. Compared to direct baking with hot air, the hot air flow acting on the mesh surface effectively improves drying efficiency. Since the meshes on both sides are close to the baking machine, the surface of the mesh may be over-baked and damaged during static baking. Furthermore, the partial obstruction by the protective frames allows the structure to simultaneously protect the mesh.

[0011] In a preferred embodiment, the central air guide mechanism includes a third support shaft, multiple second fan blades, multiple third fan blades, a first synchronous pulley, a second synchronous pulley, and a synchronous belt;

[0012] Multiple second fan blades are equidistantly arranged on the outer wall of the second support shaft, and multiple third fan blades are equidistantly arranged on the outer wall of the third support shaft, the two ends of the third support shaft being movably connected to the side bracket;

[0013] The first synchronous pulley is fixedly connected to one end of the third support shaft, and the second synchronous pulley is fixedly connected to the same end of the second support shaft. The synchronous belt is simultaneously sleeved on the first synchronous pulley and the second synchronous pulley.

[0014] By incorporating a central air guide mechanism, the reciprocating motion of the second support shaft driven by the motor simultaneously rotates multiple second and third fan blades, guiding the hot air to better contact the solar grid in the staggered protective frame on this side, thereby further optimizing drying efficiency.

[0015] In a preferred embodiment, the side air guide mechanism includes a side support, a first support shaft, a plurality of first fan blades, a plurality of gears, a plurality of racks, and a plurality of connecting rods;

[0016] One end of each of the multiple connecting rods is hinged to the outer wall of the square support frame located at the four corners, and the other end of each connecting rod is hinged to multiple racks, and the multiple racks correspond one-to-one with multiple gears and mesh with each other;

[0017] The two ends of the first support shaft are respectively connected to two gears located on the same side, and multiple first fan blades are equidistantly arranged on the outer wall of the first support shaft. The baking machine is fixedly connected to the inner wall of the side support.

[0018] One end of each rack is fixedly connected to a limiting rod, and the outer wall of the side support is fixedly connected to a limiting frame, with the limiting rod movably inserted into the limiting frame.

[0019] By incorporating a side air guide mechanism, the rack moves back and forth as the square support frame moves up and down, causing the first support shaft to rotate. During this rotation, the first support shaft expands its contact area with the hot air under the action of the first fan blades. This allows the hot air around the oven to be guided based on the different rotation directions of the first support shaft, so that the generated airflow can directly act on multiple protective frame positions, or be guided in the opposite direction to one end of the baking chamber to balance the temperature within the entire baking chamber, thereby optimizing the baking effect of the hot airflow.

[0020] As described above, a baking device for solar screen production with a protective structure includes a baking chamber and a door movably connected to the outer wall of one side of the baking chamber. The baking chamber also includes a placement mechanism, a central air guide mechanism located in the middle of the placement mechanism, side air guide mechanisms located on both sides of the placement mechanism, and a baking machine mounted on the side air guide mechanisms. The placement mechanism includes a square support frame, multiple protective frames movably connected to the square support frame, multiple through slots penetrating the protective frames, a load-bearing block fixedly connected to the outer wall of the bottom end of the protective frames, a connecting seat fixedly connected to the center position of the bottom end of the square support frame, a second support shaft fixed to the connecting seat, and a motor connected to one end of the second support shaft. The solar screen production baking device with a protective structure provided by this utility model effectively improves drying efficiency while providing protection for the screen.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] The baking device for solar screen production with a protective structure disclosed in this utility model is mainly used in the baking of solar screens.

[0028] Reference Figures 1-3A baking device for producing solar screens with a protective structure includes a baking chamber 2 and a door 1 movably connected to the outer wall of one side of the baking chamber 2. The baking chamber 2 also includes a mounting mechanism 4, a central air guide mechanism 5 located in the middle of the mounting mechanism 4, side air guide mechanisms 3 located on both sides of the mounting mechanism 4, and a baking machine 6 mounted on the side air guide mechanisms 3. The mounting mechanism 4 includes a square support frame 401, multiple protective frames 407 movably connected to the square support frame 401, multiple through slots 408 penetrating the protective frames 407, a load-bearing block 409 fixedly connected to the outer wall of the bottom end of the protective frames 407, a connecting seat 403 fixedly connected to the center position of the bottom end of the square support frame 401, a second support shaft 406 fixed to the connecting seat 403, and a motor 404 connected to one end of the second support shaft 406. In the mounting mechanism 4, the multiple protective frames 407 are movably connected to the square support frame 401. The inner wall of the rectangular support frame 401 is driven by the motor 404 to reciprocate, causing the two sides of the rectangular support frame 401 to swing back and forth. Based on the setting of the load block 409, multiple rectangular support frames 401 can be kept vertical. During the swing, multiple protective frames 407 on both sides can be staggered accordingly. The staggered multiple protective frames 407 can reduce the obstruction of adjacent protective frames 407, allowing the internal screen to have better contact with hot air. At the same time, the swing can also activate the surrounding hot air and generate a certain amount of hot air flow. Compared with direct baking by hot air, the hot air flow acting on the screen surface can effectively improve the drying efficiency. At the same time, since the screens on both sides are close to the baking machine 6, the screen surface may be over-baked and damaged during static baking. Based on the partial obstruction of the protective frame 407, the structure can also protect the screen.

[0029] Reference Figure 2 and Figure 3 In a preferred embodiment, the inner walls of the opposite sides of the square support frame 401 are provided with a plurality of connection holes 402, and the outer walls of the opposite sides of each protective frame 407 are fixedly connected with a connecting rod 410, and the plurality of connecting rods 410 are respectively movably disposed in the connection holes 402.

[0030] Reference Figure 2 In a preferred embodiment, a side support 405 is fixedly connected to the bottom inner wall of the baking chamber 2, and a second support shaft 406 passes through the side support 405. The motor 404 is fixedly connected to one side outer wall of the side support 405.

[0031] Reference Figure 2 In a preferred embodiment, the central air guide mechanism 5 includes a third branch shaft 503, a plurality of second fan blades 501, a plurality of third fan blades 503, a first synchronous pulley 504, a second synchronous pulley 506, and a synchronous belt 505.

[0032] Reference Figure 2In a preferred embodiment, a plurality of second fan blades 501 are equidistantly disposed on the outer wall of the second support shaft 406, and a plurality of third fan blades 503 are equidistantly disposed on the outer wall of the third support shaft 503, the two ends of the third support shaft 503 being movably connected to the side bracket 405.

[0033] Reference Figure 2 In a preferred embodiment, the first synchronous pulley 504 is fixedly connected to one end of the third support shaft 503, and the second synchronous pulley 506 is fixedly connected to the same end of the second support shaft 406. The synchronous belt 505 is simultaneously sleeved on the first synchronous pulley 504 and the second synchronous pulley 506. In the central air guiding mechanism 5, as the motor 404 drives the second support shaft 406 to reciprocate, the first synchronous pulley 504 and the second synchronous pulley 506 are linked together to drive the third support shaft 503 to rotate in the same direction. This drives multiple second fan blades 501 and third fan blades 502 to rotate, guiding the hot air. Based on this linkage structure, when one side of the square support frame 401 falls and multiple protective frames 407 are staggered and approach the bottom of the baking chamber 2, the air guiding direction of the second fan blades 501 and third fan blades 502 is exactly corresponding to it, so that the hot air can better contact the solar grid in the staggered protective frame 407 on that side, further optimizing the drying efficiency.

[0034] Reference Figure 4 In a preferred embodiment, the side air guide mechanism 3 includes a side support 301, a first support shaft 306, a plurality of first fan blades 305, a plurality of gears 307, a plurality of racks 304, and a plurality of connecting rods 308.

[0035] Reference Figure 4 In a preferred embodiment, one end of each of the multiple connecting rods 308 is hinged to the outer wall of the square support frame 401 at the four corners, and the other end of each connecting rod 308 is hinged to a multiple racks 304, and the multiple racks 304 correspond one-to-one with a multiple gears 307 and mesh with each other.

[0036] Reference Figure 4 In a preferred embodiment, the two ends of the first support shaft 306 are respectively connected to two gears 307 located on the same side, and a plurality of first fan blades 305 are equidistantly arranged on the outer wall of the first support shaft 306, and the baking machine 6 is fixedly connected to the inner wall of the side support 301.

[0037] Reference Figure 4In a preferred embodiment, one end of each rack 304 is fixedly connected to a limiting rod 303, and the outer wall of the side support 301 is fixedly connected to a limiting frame 302, with the limiting rod 303 movably inserted into the limiting frame 302. In the side air guide mechanism 3, as the two sides of the square support frame 401 move up and down, the rack 304 can be driven to reciprocate under the action of the connecting rod 308 and the action of the limiting rod 303 translating within the limiting frame 302. During the reciprocating motion of the rack 304... In the process, based on the meshing state of the rack 304 and the gear 307, the first support shaft 306 can be driven to rotate. During the rotation of the first support shaft 306, the contact area with the hot air can be expanded under the action of the first fan blade 305. Thus, the hot air around the baking machine 6 can be guided according to the different rotation directions of the first support shaft 306, so that the generated airflow can directly act on the positions of multiple protective frames 407, or be guided in the opposite direction to one end of the baking chamber 2 so that the temperature in the entire baking chamber 2 tends to be balanced, thereby optimizing the baking effect of the hot airflow.

[0038] Working principle: In the mounting mechanism 4, multiple protective frames 407 are movably connected to the inner wall of the square support frame 401. The square support frame 401 is driven to reciprocate by the motor 404, which can make the two sides of the square support frame 401 swing back and forth. Based on the setting of the load block 409, the multiple square support frames 401 can be kept vertical. During the swing, the multiple protective frames 407 on both sides can be staggered accordingly. The staggered multiple protective frames 407 can reduce the obstruction of adjacent protective frames 407, so that the internal screen can better contact the hot air. At the same time, the swing can also activate the surrounding hot air and generate a certain amount of hot air flow. Compared with direct baking by hot air, the hot air flow can effectively improve the drying efficiency by acting on the screen surface. At the same time, since the screens on both sides are close to the baking machine 6, the screen surface may be over-baked and damaged during static baking. Based on the partial shielding of the protective frame 407, the structure can also protect the screen.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
