Description

Technical Field

[0001] This utility model relates to the technical field of protective plate mechanisms, specifically a scratch-resistant protective plate mechanism for drying lines. Background Technology

[0002] A drying line is an automated equipment used in industrial production to achieve "continuous conveying + batch drying." Essentially, it uses a "conveyor system" to uniformly feed workpieces (or materials) into a "heating and drying zone," where moisture and solvents are removed at a preset temperature and time, ultimately outputting a dried finished product. Its core value lies in replacing the intermittent operation of traditional "static drying (such as an oven)," significantly improving production efficiency, ensuring drying uniformity, and adapting to the continuous production needs of assembly lines.

[0003] In existing technologies, during the actual operation of a drying line, workpieces are prone to positional shifts due to fluctuations in conveying speed, shifts in the workpiece's center of gravity, or deviations in the conveying path calibration when moving on the conveying device. This shift not only leads to unstable workpiece conveying conditions but also causes direct collisions between the workpiece and the metal frame on the side of the conveying device, resulting in quality problems such as scratches on the workpiece surface and edge deformation, which seriously affects the finished product qualification rate. At the same time, traditional drying devices mostly have a single hot air vent at the top of the drying chamber, causing the hot air to flow in a straight line in a single direction after entering the chamber. This single airflow path is difficult to cover the entire chamber area and easily creates airflow dead zones in the corners of the chamber and in the workpiece stacking area. This results in significant differences in the degree of heating of workpieces at different locations. Some workpieces are not thoroughly dried due to insufficient heating, while others suffer material damage due to localized overheating, ultimately causing unstable overall drying results. Utility Model Content

[0004] The purpose of this utility model is to provide a scratch-resistant guard plate mechanism for drying lines, in order to solve the problems mentioned in the background art, where workpieces are prone to positional shifts due to fluctuations in conveying speed, center of gravity shifts, or path calibration deviations during the operation of the drying line. This not only leads to unstable conveying but also causes surface scratches and edge deformation due to collisions with the side metal frame, affecting the finished product qualification rate. At the same time, traditional drying devices often only have a single hot air vent at the top of the chamber, and the unidirectional flow of hot air makes it difficult to cover the entire area, easily forming airflow dead zones, causing uneven heating of the workpieces, resulting in incomplete drying or local overheating damage, leading to unstable overall drying effect.

[0009] According to the preferred embodiment of this technical solution, the synchronization component includes a transmission roller fixedly connected to the other end of the guide rod and a synchronization belt connected between the transmission rollers. The synchronization belt is used to drive the transmission rollers on both sides to rotate synchronously.

[0010] Based on the preferred embodiment of this technical solution, two sets of both the guide rod and the drive roller are provided, and the two sets of guide rod and drive roller are symmetrically distributed on the drying line frame.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6This utility model provides an embodiment of a scratch-resistant guard plate mechanism for a drying line, including a drying line frame 1, a drying assembly mounted on the drying line frame 1, a second drive assembly mounted on the drying assembly, a support plate 21 fixedly connected to the drying line frame 1, a guide rod 22 rotatably connected to the support plate 21, a synchronization assembly mounted between the guide rods 22, a rotating bracket 25 fixedly connected to the middle end of the guide rod 22, a movable bracket 26 rotatably connected at one end to the rotating bracket 25, a centering positioning frame 27 slidably connected to the support plate 21, a guard plate body 28 fixedly connected to the centering positioning frame 27, a rotating roller 29 rotatably connected to the guard plate body 28, and a first drive assembly mounted on the support plate 21. The other end of the movable bracket 26 is rotatably connected to the centering positioning frame 27. The rotating roller 29 and the guard plate body 28 are disposed on the drying line frame 1. The first drive assembly is used to drive... The guide rod 22 is rotated, and the synchronization component is used to drive the guide rods 22 on both sides to rotate synchronously. The drying component is used to dry the workpieces conveyed on the drying line frame 1. Through the synergistic effect of the first drive component and the synchronization component, the guide rods 22 on both sides of the drying component on the drying line frame 1 can be driven to rotate synchronously, thereby driving the rotating bracket 25 fixed in the middle of the guide rod 22 to rotate as well. Then, the movable bracket 26 rotatably connected to the rotating bracket 25 at one end drives the two sets of centering positioning brackets 27 slidably connected to the support plate 21 to move closer or further away from each other, thereby accurately achieving the centering positioning of the workpieces conveyed on the drying line frame 1, effectively avoiding the problem of unstable conveying caused by positional deviation during the conveying process of the workpieces. At the same time, through the rotating roller 29 rotatably connected to the guard plate body 28, the stability of the workpieces during conveying can be further improved, reducing quality defects such as scratches on the workpiece surface and edge deformation.

[0019] Please see Figure 3 A further solution based on this embodiment is as follows: the support plate 21 has a sliding groove at the corresponding position of the centering positioning frame 27, and the centering positioning frame 27 is slidably connected to the sliding groove of the support plate 21. By opening the sliding groove on the support plate 21 at the position corresponding to the centering positioning frame 27, a clear guiding path is provided for the sliding of the centering positioning frame 27, which can effectively avoid the centering positioning frame 27 from deviating or getting stuck when sliding, and ensure that the centering positioning frame 27 can stably drive the guard plate body 28 to adjust its position, thereby ensuring the accuracy of centering the workpiece and reducing the workpiece conveying deviation problem caused by the unstable sliding of the centering positioning frame 27.

[0020] Please see Figure 3A further solution based on this embodiment is as follows: the support plate 21 has a through groove at the corresponding position of the centering positioning frame 27, and the centering positioning frame 27 is slidably connected to the through groove of the support plate 21. By opening a through groove on the support plate 21 at the position corresponding to the centering positioning frame 27, it is convenient to rotate and connect with the movable bracket 26, thereby improving practicality and enhancing the protective effect on the drying line frame 1.

[0021] Please see Figure 3 A further solution based on this embodiment is as follows: The first drive assembly includes a worm gear 210 fixedly connected to one end of the guide rod 22, a semi-circular block 212 fixedly connected to the top of the support plate 21 and a motor 211, and a worm 213 rotatably connected to the semi-circular block 212. The worm 213 is fixedly connected to the output end of the motor 211. The worm gear 210 meshes with the worm 213. The motor 211 is used to drive the worm 213 to rotate. Power is provided by the motor 211 in the first drive assembly to drive the worm 213. The 13 rotates stably on the semicircular block 212. By using the meshing transmission between the worm gear 213 and the worm wheel 210 at one end of the guide rod 22, the rotation speed and angle of the guide rod 22 can be precisely controlled, avoiding inaccurate positioning caused by excessive rotation or angular deviation of the guide rod 22. At the same time, the structure of the worm wheel 210 and worm gear 213 has a self-locking characteristic. After the motor 211 stops working, it can firmly fix the position of the guide rod 22, preventing the guide rod 22 from rotating due to external force and causing the centering positioning frame 27 to shift, thus ensuring the stable positioning state of the guard plate body 28 for the workpiece.

[0022] Please see Figure 2 A further solution based on this embodiment is as follows: The synchronization component includes a transmission roller 23 fixedly connected to the other end of the guide rod 22 and a synchronization belt 24 drivingly connected between the transmission rollers 23. The synchronization belt 24 is used to drive the transmission rollers 23 on both sides to rotate synchronously. The transmission rollers 23 on the other end of the guide rods 22 on both sides are connected through the synchronization belt 24 in the synchronization component. When the first drive component drives one side of the guide rod 22 to rotate, the transmission roller 23 will drive the other side of the transmission roller 23 and the guide rod 22 to rotate synchronously through the synchronization belt 24, ensuring that the rotation rhythm of the two guide rods 22 is consistent, avoiding the deviation of the centering positioning frame 27 due to the asynchronous rotation of the two guide rods 22, thereby ensuring that the positioning force of the two sets of guard plate bodies 28 on both sides of the workpiece is balanced, and the workpiece can be centered and positioned when entering the drying area of ​​the drying component and leaving, thus improving the protection.

[0023] Please see Figure 2A further solution based on this embodiment is as follows: two sets of guide rods 22 and transmission rollers 23 are provided. The two sets of guide rods 22 and transmission rollers 23 are symmetrically distributed on the drying line frame 1. By symmetrically distributing the two sets of guide rods 22 and transmission rollers 23 on the drying line frame 1, the central positioning frame 27, guard plate body 28 and other components on both sides of the drying line frame 1 can form a symmetrical positioning structure, apply a uniform guiding force to both sides of the workpiece, and avoid the workpiece from tilting or shifting due to excessive force on one side; at the same time, the symmetrical distribution structure can keep the workpiece in the central position of the drying line frame 1 during the conveying process.

[0024] Please see Figure 4-6 A further embodiment of this solution is as follows: The drying assembly includes a drying chamber 31 fixedly connected to the center of the drying line frame 1, a temperature sensor 32 fixedly connected to the drying chamber 31, a controller 33 fixedly connected to one side of the drying chamber 31, a heat-insulating cloth strip 34 fixedly connected at one end to the inlet and outlet of the drying chamber 31, a rotating rod 35 rotatably connected to the drying chamber 31, a square frame 36 fixedly connected to the inner side of the rotating rod 35, and an electric heating tube 37 and a blower fan 38 fixedly connected to the inner side of the square frame 36. The temperature sensor 32 is electrically connected to the controller 33, the electric heating tube 37 is electrically connected to the controller 33, and the blower fan 38 is electrically connected to the controller 33. The second drive assembly is used to drive... The rotating rods 35 on both sides swing back and forth synchronously. The temperature sensor 32 in the drying assembly monitors the temperature inside the drying chamber 31 in real time and transmits the data to the controller 33. The controller 33 can automatically adjust the heating state of the electric heating tube 37 according to the set temperature to ensure a stable temperature inside the drying chamber 31 and prevent the workpiece from being damaged due to excessive temperature or not drying thoroughly due to excessive temperature. The heat insulation strip 34 can reduce heat loss at the entrance and exit of the drying chamber 31 and reduce energy consumption. In conjunction with the second drive assembly, the rotating rods 35, the square frame 36, the electric heating tube 37, and the blower fan 38 swing back and forth, which can make the hot air diffuse evenly in the drying chamber 31, avoid the formation of airflow dead zones, ensure that all parts of the workpiece are heated evenly, and improve the drying quality.

[0025] Please see Figure 5A further embodiment of this solution is as follows: The second drive assembly includes a circular gear 39 fixedly connected to one end of the rotating rod 35, a rack 310 slidably connected to the drying chamber 31, a connecting rod 311 fixedly connected to the inner side of the rack 310, a fixing lug 312 fixedly connected to the center of the connecting rod 311, and a hydraulic telescopic rod 313 fixedly connected to the same side of the drying chamber 31 and the circular gear 39. The circular gear 39 meshes with the rack 310. The fixing lug 312 is fixedly connected to the telescopic end of the hydraulic telescopic rod 313. The hydraulic telescopic rod 313 is electrically connected to the controller 33, and the controller 33 in the second drive assembly controls the hydraulic telescopic rod 313. The telescopic mechanism allows the fixed lug 312, connecting rod 311, and rack 310 to slide on the drying chamber 31. The meshing transmission between the rack 310 and the circular gear 39 at one end of the rotating rod 35 precisely controls the swing angle and frequency of the rotating rod 35, preventing excessive or insufficient swing amplitude from affecting the hot air coverage. The hydraulic telescopic rod 313 provides stable power, ensuring that the rotating rod 35 drives the square frame 36, electric heating tube 37, and blower fan 38 to swing smoothly, reducing transmission failures. Simultaneously, the high transmission precision of the rack and pinion 310 allows the rotating rods 35 on both sides to move synchronously, further ensuring uniform hot air distribution within the drying chamber 31 and improving the workpiece drying effect.

[0026] The temperature sensor 32 is model CWDZ11, and the working principles of the temperature sensor 32, controller 33, electric heating tube 37, blower fan 38 and hydraulic telescopic rod 313 are common technical means in this field, so they will not be described in detail.

[0027] The synchronization component can also adopt other structures in the existing technology, such as sprockets and chains, which replace the transmission roller 23 and the timing belt 24. The advantages are: the transmission ratio of sprockets and chains is more precise, which can further ensure the synchronicity of the rotation of the smooth rods 22 on both sides of the drying line frame 1, and avoid inconsistent movement of the centering positioning frame 27 due to transmission deviation; and its wear resistance and tensile strength are better. At the same time, sprockets and chains have a high tolerance for impurities and are not prone to slippage due to dust contamination like the timing belt 24. They can always maintain stable transmission and ensure the reliability of centering and positioning of the workpiece.

[0028] Working principle: First, the workpiece is conveyed on the drying line frame 1. At this time, the motor 211 in the first drive assembly starts first, driving the worm 213 fixed at its output end to rotate stably on the semi-circular block 212 on the top of the support plate 21. Since the worm 213 meshes with the worm wheel 210 at one end of the guide rod 22, it drives the guide rod 22 to rotate on the support plate 21. At the same time, the synchronization assembly ensures that the two sets of symmetrically distributed guide rods 22 rotate synchronously through the synchronous belt 24 between the transmission rollers 23 at the other end of the two guide rods 22, so that the workpiece can be in a centered state when entering and leaving the drying chamber 31. To improve the stability of workpiece conveying, the rotation of the guide rod 22 drives the rotating bracket 25 fixed in its middle to move synchronously. The rotating bracket 25, through the movable bracket 26 rotatably connected at one end, pulls the centering positioning frame 27 slidably connected to the sliding groove and through groove of the support plate 21, causing the two sets of centering positioning frames 27 to move closer or further apart, thereby accurately centering the workpiece during conveying. The guard plate body 28 fixed on the centering positioning frame 27 and the rotating roller 29 rotatably connected to the guard plate body 28 will further conform to both sides of the workpiece, reducing friction during workpiece conveying and preventing it from colliding with the drying line frame 1, ensuring... The workpiece enters the drying assembly stably and without scratches. Once the workpiece enters the drying chamber 31, which is fixed in the center of the drying line frame 1, the drying assembly begins operation. The temperature sensor 32 on the drying chamber 31 monitors the indoor temperature in real time and transmits the data to the controller 33 on one side. The controller 33 automatically adjusts the heating power of the electric heating tube 37 inside the square frame 36 according to the preset temperature. Simultaneously, the blower fan 38 starts blowing hot air. At this time, the second drive assembly starts under the control of the controller 33. The hydraulic telescopic rod 313 extends and retracts, driving the fixed lug 312 and connecting rod 311 fixed at its telescopic end to move. The connecting rod 311 carries... The rack 310, which is slidably connected to the drying chamber 31, slides. Since the rack 310 meshes with the circular gear 39 at one end of the rotating rod 35, it drives the rotating rod 35 to swing back and forth synchronously on the drying chamber 31. The rotating rod 35 then drives the inner square frame 36 and the electric heating tube 37 and blower fan 38 inside the frame to swing together, so that the hot air is evenly diffused in the drying chamber 31, avoiding the formation of airflow dead zones and ensuring that all parts of the workpiece are heated evenly. The heat insulation cloth strips 34 at the entrance and exit of the drying chamber 31 can reduce the loss of heat in the chamber. Finally, the workpiece is stably conveyed and protected from scratches while completing a uniform and efficient drying process.

[0029] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
