Description

Technical Field

[0001] This utility model relates to the field of roller screen technology, and in particular to a scale baffle device for quickly adjusting the gap between roller screens. Background Technology

[0002] In fields such as ore screening and grain processing, roller screens are key equipment for material grading, and the accuracy of the gap between the screen rollers directly affects the screening quality. Traditional roller screen gap adjustment relies heavily on manual movement of each roller, followed by bolt fixing, a cumbersome process that makes it difficult to ensure consistent gaps across multiple sets of rollers. As industrial production demands higher screening efficiency and precision, frequent gap adjustments based on material particle size variations are required, and traditional methods are no longer sufficient for continuous and automated production. Currently, while some equipment uses mechanical structures for gap adjustment, it struggles to balance the synchronicity of roller movement with the continuity of rotation, affecting the stability of the screening effect.

[0003] Existing roller screen gap adjustment devices require machine shutdown for adjustment and are mostly for independent adjustment of a single roller. This is not only time-consuming and labor-intensive but also prone to causing inconsistent gaps between adjacent rollers, affecting screening accuracy. While some linkage adjustment structures can achieve synchronous movement of multiple rollers, they are often independent of the roller rotation drive system, requiring rotation to be interrupted during adjustment and making real-time fine-tuning impossible during screening operations. Furthermore, the fixed structure after adjustment is prone to loosening due to vibration, causing the gap to change again, requiring frequent calibration, increasing maintenance costs and downtime, and hindering the improvement of production efficiency.

[0004] Therefore, a new scale baffle device for quickly adjusting the gap between roller screens is proposed to solve the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this invention is to provide a scale baffle device for quickly adjusting the gap between roller screens. By incorporating a detection component, it solves the problems of existing roller screen gap adjustment devices requiring machine stoppage for adjustment, and often involving independent adjustment of a single roller. This is not only time-consuming and labor-intensive but also prone to causing inconsistent gaps between adjacent screen rollers, affecting screening accuracy. While some linkage adjustment structures can achieve synchronous movement of multiple rollers, they are often independent of the rotation drive system of the screen rollers, requiring rotation interruption during adjustment and making real-time fine-tuning impossible during screening operations. Furthermore, the fixed structure after adjustment is prone to loosening due to vibration, causing the gap to change again, requiring frequent calibration, increasing maintenance costs and downtime, and hindering the improvement of production efficiency.

[0007] 2. Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0011] Furthermore, a first motor is installed at the end of the bidirectional lead screw away from the first bearing, and the end of the first motor away from the bidirectional lead screw is connected to the right end of the mounting frame. This design can drive the operation of the entire device.

[0012] Furthermore, a first sliding groove is provided on the inner side wall of the mounting frame, and two sliding rods are symmetrically installed in the first sliding groove.

[0013] Furthermore, a second sliding groove is provided on the support plate, and two sliders are symmetrically installed in the second sliding groove, with each slider being connected to the corresponding third bearing.

[0014] Furthermore, the mounting frame is equipped with four crossbars at the bottom, and a set of symmetrical brackets is installed on each of the two crossbars at both ends. A collection box is installed at the bottom of the four crossbars.

This design can effectively prevent the material being screened from leaking out, and both second baffles can move synchronously with the screen roller to adjust the gap.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] The beneficial effects of this invention lie in achieving rapid and synchronous adjustment of the screen roller gap without affecting the rotation of the screen rollers.

[0035] Mounting frame 210, with connecting hole 213, through which a bidirectional lead screw 111 is installed. Two symmetrical moving blocks 115 are mounted on the bidirectional lead screw 111, and a connecting rod 114 is mounted on either moving block 115. A second bearing 121 is mounted on the other end of the left connecting rod 114, and a second motor 120 is mounted on the other end of the right connecting rod 114. A rotating shaft 122 is mounted on the end of both the second bearing 121 and the second motor 120 away from the bidirectional lead screw 111. Any one of the rotating shafts 122... Each of the two third bearings 124 is mounted on a third bearing 124. A support plate 220 is mounted on the end of each third bearing 124 away from the screen roller 123. A first pulley 130 is mounted on the right end of the rotating shaft 122, and a second pulley 131 is mounted on the left end of the rotating shaft 122. A mounting plate 140 is mounted on the end of the support plate 220 closest to the screen roller 123. A cylinder 141 is mounted on the bottom of the mounting plate 140. A pneumatic rod 142 is mounted on the cylinder 141. A mounting rod 143 is mounted on the end of the pneumatic rod 142 closest to the screen roller 123. The mounting rod 143 is located away from the pneumatic rod 141. A limiting ring 144 is installed at one end of the 2, and a third pulley 132 is installed on the limiting ring 144. Belts 133 are installed on the first pulley 130, the second pulley 131, and the third pulley 132. A first bearing 112 is installed at the left end of the bidirectional lead screw 111, and the end of the first bearing 112 near the bidirectional lead screw 111 is connected to the left end of the mounting frame 210. A first motor 110 is installed at the end of the bidirectional lead screw 111 away from the first bearing 112, and the end of the first motor 110 away from the bidirectional lead screw 111 is connected to the right end of the mounting frame 210. A first sliding groove 214 is provided on the inner sidewall of the 210, and two sliding rods 113 are symmetrically installed in the first sliding groove 214. Each sliding rod 113 is connected to a corresponding moving block 115. A second sliding groove 221 is provided on the support plate 220, and two sliders 125 are symmetrically installed in the second sliding groove 221. Each slider 125 is connected to a corresponding third bearing 124. Four crossbars 230 are installed at the bottom of the mounting frame 210, and a set of symmetrical brackets 240 is installed on each of the two crossbars at both ends. A collection box 250 is installed at the bottom of the four crossbars 230.

[0036] Working principle: When material screening is required, the gap between the two screen rollers 123 is adjusted according to the size of the material to be screened. Adjustment is achieved by starting the motor, which drives the bidirectional lead screw 111 to rotate. The rotation of the bidirectional lead screw 111 causes two moving blocks 115 to move relative to or relative to each other, adjusting the distance between the screen tubes. Then, the second motor 120 is started. The rotation of the second motor 120 drives the corresponding rotating shaft 122 to rotate. The rotation of the rotating shaft 122 drives the belt 133 to rotate via the first pulley 130. 3. When rotating, it drives the second pulley 131 to rotate, and the second pulley 131, in turn, drives another rotating shaft 122 to rotate. In this design, when the two rotating shafts 122 rotate synchronously, they can also drive the two screen rollers 123 to rotate in the same direction. Furthermore, the cylinder 141 pushes its air rod 142 downward. When the air rod 142 moves downward, it drives the limiting ring 144 to move downward through the mounting rod 143. When the limiting ring 144 moves, it pulls the belt 133 downward through the connected third pulley 132, so that the belt 133 always maintains sufficient tension.

[0037] Two symmetrical first baffles 310 are installed on the crossbar 230. Each of the first baffles 310 has a third sliding groove 340 and a fourth sliding groove 350. Two symmetrical second baffles 330 are installed between the two first baffles 310. Each of the rotating shafts 122 passes through the third sliding groove 340. Each of the second baffles 330 has a symmetrical support rod 360 installed on it. Each of the support rods 360 has an installation ring 370 installed at its bottom end. Each of the support rods 360 passes through the fourth sliding groove 350. Each of the installation rings 370 is installed on the corresponding rotating shaft 122.

[0038] Working principle: When the two rotating shafts 122 move, the two sets of mounting rings 370 installed on the rotating shafts 122 will drive the corresponding second baffles 330 to move synchronously, so that the corresponding material can always be kept on the upper end of the screen rollers 123 for screening.
