Description

Technical Field

[0001] This utility model relates to roller screen technology, specifically a flexible and adjustable insert plate assembly for roller screens. Background Technology

[0002] The screen surface of a roller screen consists of many parallel rollers with screen discs mounted on them in an alternating pattern. The rollers rotate via sprockets or gears, and their rotation direction is the same as the material flow direction. Because the screen rollers are arranged at different working angles, the material moves faster at higher working angles and slower at lower working angles. When the material at these two different speeds converges at a certain point on the screen surface, it begins to move axially, thus ensuring a uniform distribution of material on the screen surface and improving screening efficiency.

[0003] In the material screening process, the fixed baffles of traditional roller screens may lead to low screening efficiency due to their inability to adapt to the characteristics of different materials. For example, when processing materials with high moisture content or high viscosity, the fixed baffles are prone to clogging, thus affecting the progress of the entire production process. Therefore, we propose a flexible and adjustable baffle assembly for roller screens to solve the above-mentioned problems. Utility Model Content

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figures 1-4 As shown, a flexible and adjustable insert plate assembly for a roller screen includes a screen frame 1, an oblique cut groove 2 on the screen frame 1, and a guide groove 3 at the middle of the rear side of the screen frame 1. The oblique cut groove 2 is used to install a guide rail frame 4, and the guide groove 3 is used to guide the push plate 11.

[0021] The adjustment assembly includes a guide rail frame 4 inserted into the inclined groove 2. The top and bottom inner walls of the guide rail frame 4 are provided with several sets of guide structures. The guide structure includes a fixed shaft 5 fixedly connected to the guide rail frame 4. A guide sleeve 6 is rotatably connected to the outer side of the fixed shaft 5. An insert plate body 7 is also provided inside the guide rail frame 4. An adjustable insert plate 8 is rotatably connected inside the insert plate body 7. A positioning plate 9 is fixedly connected to the upper side of the rear inner wall of the screen frame 1. A lead screw 10 is rotatably connected between the positioning plate 9 and the bottom inner wall of the screen frame 1. A push plate 11 is threadedly connected to the outer side of the lead screw 10. The push plate 11 is slidably connected to the inner side of the guide groove 3. A drive gear 12 is rotatably connected to the rear lower inner wall of the screen frame 1. A driven gear 13 is fixedly connected to the outer lower side of the lead screw 10. The drive gear 12 and the driven gear 13 mesh. A rotating wheel 14 is also fixedly connected to one end of the central shaft of the drive gear 12.

[0022] It should be noted that the guide rail frame 4 is used to install multiple fixed shafts 5 and facilitates connection with the screen frame 1. The fixed shafts 5 are used to install guide sleeves 6. The guide sleeves 6 are used to convert the sliding friction of the insert plate body 7 during movement into rolling friction, reducing friction. The adjustable insert plate 8 and the insert plate body 7 are designed separately, allowing the tilt angle of the insert plate 8 in the screen frame 1 to be changed as needed, facilitating the adaptation to different materials and guiding them. The positioning plate 9 is used to position and install the lead screw 10. The push plate 11 is used to lift and lower as the lead screw 10 rotates by threaded engagement with the lead screw 10, and is lifted or lowered by its end. The adjustable insert plate 8, the driving gear 12, and the driven gear 13 are all bevel gears. They mesh with each other to change the transmission direction. The rotating wheel 14 is easy for the operator to hold and rotate, which in turn drives the lead screw 10 to rotate. Through the set adjustment components, the angle and position of the insert plate can be given according to the specific conditions on site, ensuring that the material can pass through the roller screen smoothly, which greatly improves the screening efficiency, reduces downtime caused by blockage and other problems, and provides a strong guarantee for the continuous production of enterprises. At the same time, its easy installation and disassembly features also make maintenance work more convenient and reduce downtime maintenance time.

[0023] An arc groove 15 is provided on the insert plate body 7. A blocking disc 16 is rotatably connected inside the arc groove 15. The shape of the blocking disc 16 is the same as that of the arc groove 15. When it is completely located inside the arc groove 15, the insert plate body 7 can move within the guide rail frame 4. A positioning groove is provided on the guide rail frame 4. The radius of the positioning groove is adapted to the radius of the arc groove 15. When the blocking disc 16 rotates into the positioning groove, it will block the movement of the insert plate body 7 on the guide rail frame 4, thereby limiting the lateral movement of the insert plate body 7 during operation and improving the stability of the insert plate during operation.

[0024] The length of the adjustable insert plate 8 is adapted to the distance between the inner walls on the left and right sides of the screen frame 1. The upper side of the lower end of the adjustable insert plate 8 is a right angle. The right angle can avoid gaps between it and the guide rail frame 4, prevent raw materials from getting stuck in the gaps, thereby improving the stability during operation and facilitating cleaning.

[0025] The adjustable insert plate 8 and the insert plate body 7 both abut against several guide sleeves 6. One end of the push plate 11 abuts against the bottom of the adjustable insert plate 8. The rotation of the guide sleeves 6 can reduce the moving friction when pulling the insert plate body 7, making the operation simple and convenient.

[0026] In specific implementation of this utility model: before material feeding is required, the insert plate body 7, together with the adjustable insert plate 8, is pushed into the screen frame 1, and the blocking disc 16 is rotated to make it lock into the positioning groove. Then, according to the material requirements, the rotating wheel 14 is rotated to drive the drive gear 12 to rotate. The drive gear 12 meshes with the driven gear 13 to drive the lead screw 10 to rotate. Through the threaded engagement between the push plate 11 and the lead screw 10, and through the guide groove 3 to limit the push plate 11, the height of the push plate 11 is changed, so that one end pushes or releases the adjustable insert plate 8, thereby making the adjustable insert plate 8 rotate in the insert plate body 7 and change the angle.

[0027] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
