Description

Technical Field

[0001] The utility model relates to auxiliary equipment technology of a conveyor belt, in particular to a conveyor steel belt assembly with a deviation correcting device. Background Art

[0002] Before brewing liquor, the grains need to be husked, which is usually done by placing the grains in a bran sifter. The bran sifter is equipped with a conveying steel belt with holes. Some bran sifters separate the husks above the steel belt, and the separated husks fall onto the conveying steel belt. The husks are generally formed into powder or finer particles after strong vibration and centrifugation, and fall into the husk collection box through the holes on the conveying steel belt. The grains stay on the conveying steel belt and are transported to the bran sifter outlet for collection. Some bran sifters directly set a vibrating screening device on the conveying steel belt. During the operation of the conveying steel belt, the grains on the conveying steel belt can complete the husk separation process, and the husks can be sieved through the holes on the conveying steel belt and fall into the husk collection box.

[0003] The existing bran screening machine has a conveyor belt width of 0.6 to 1 meter or more, and a length of 3 to 10 meters or more. The steel belt is very rigid and brittle, and is prone to left and right deviations during the rotation of the roller. After the conveyor belt deviates left and right, it will collide with the protective steel on both sides of the frame, causing the curling of the conveyor belt to be damaged, shortening the service life of the steel belt and increasing the replacement cost.

[0004] There are also devices for correcting the deviation of steel strips in the prior art, but it is usually found that the deviation position is not accurate enough. In particular, when a long steel strip deviates, the deviation scale is not the same along the entire length. There is always a section with a larger deviation scale, and it is difficult for the correction device to adjust the position, because it is also difficult to avoid the situation where part of the steel strip curls due to untimely correction; and correction is often performed at the point where the deviation scale is the largest, so that the correction can be completed in the shortest time, which can save energy and achieve the best correction effect.

[0005] To this end, the utility model provides a conveyor steel belt assembly with a deviation correction device to solve the above-mentioned problems of the prior art. Summary of the invention

[0029] The conveyor steel belt 3 can be defined in sections according to the position to which it runs, that is, the section of the conveyor steel belt 3 running to the position between the horizontal vertices of the two rotating rollers 2 is called the upper section steel belt 31, and the section of the conveyor steel belt 3 running to the position between the horizontal lowest points of the two rotating rollers 2 is called the lower section steel belt 32. The upper section steel belt 31 and the lower section steel belt 32 here do not refer to a specific section of the conveyor steel belt 3, but refer to the subsections of any part of the conveyor steel belt 3 when it rotates to the above-mentioned specified position.

[0030] like Figure 1 , 6 As shown in Figures 7 and 8, the frame 1 includes an upper cross frame 11 and a lower cross frame 12, and both the upper cross frame 11 and the lower cross frame 12 are arranged along the length direction of the conveyor steel belt 3. There are two upper cross frames 11, which are respectively located on the left and right outer sides of the upper section steel belt 31, and the upper cross frames 11 and the conveyor steel belt 3 are parallel to each other. A group of collision sensing array groups are respectively installed on the two upper cross frames 11, and the collision sensing array group is composed of a plurality of collision sensing members 5 arranged at intervals along a straight line.

[0031] like Figure 2 As shown, the specific structure of the collision sensing member 5 is as follows: it includes a central axis column 51, which is vertically fixedly mounted on the upper cross frame 11. The outer periphery of the central axis column 51 is rotatably sleeved with a rotating sleeve 53 through a first bearing 52. A collision sensor 55 is fixedly installed between the rotating sleeve 53 and the central axis column 51, and the collision sensor 55 is located on the side of the outer periphery of the central axis column 51 close to the conveyor belt 3.

The buffer layer 54 can be rubber or any elastic buffer material to prevent the collision sensor 51 and other components from being damaged by collision.

[0032] A position sensor 56 is also installed on the top of the central axis column 51, and the position sensor 56 is also connected to the PLC control module signal. The position sensor 56 is provided with an independent position number signal for each collision sensing element 5 where it is located, that is, Figure 6As shown, collision sensing array groups "L" and "R" are respectively arranged on the two upper horizontal frames 11. Gaps are left between the two collision sensing array groups and the left and right side walls of the conveyor steel belt 3. In the collision sensing array group "L", the positions of each collision sensing element 5 are named "L1", "L2" ... "Ln" in sequence; in the collision sensing array group "R", the positions of each collision sensing element 5 are named "R1", "R2" ... "Rn" in sequence; wherein, the collision sensing elements of "L1" and "R1" are arranged opposite to each other, and so on.

[0033] like Figure 3-5 As shown, the specific structure of the deviation correction device 6 is as follows: the deviation correction device 6 includes a fixed bracket 61. Sliding wheels 62 are fixedly installed on the left and right outer side walls of the fixed bracket 61. The lower cross frame 12 is provided with a frame slide groove 121, and the sliding wheels 62 on both sides of the fixed bracket 61 are respectively installed on the frame slide groove 121 on both sides, and the sliding wheels 62 can slide back and forth on the frame slide groove 121.

[0034] A support plate 13 is provided on the frame 1, and a servo motor 71 is installed on the support plate 13. The output end of the servo motor 71 is transmission-connected to a screw rod 72, and the other end of the screw rod 72 is rotatably mounted on the lower cross frame 12 through a bearing. The screw rod 72 is located on an outer side of the conveyor steel belt 3, and is arranged parallel to the front-to-back direction of the conveyor steel belt 3. A threaded hole 63 is provided on the fixed bracket 61 of the deviation correction device 6, which runs horizontally therethrough. The screw rod 72 is inserted into the threaded hole 63 and matches each other, that is, the deviation correction device 6 is realized by the servo motor 71 to slide back and forth on the lower cross frame 12 along the front-to-back direction of the conveyor steel belt 3. The servo motor 71 is connected to the PLC control module by telecommunication, and the front-to-back movement of the deviation correction device 6 can be controlled by the PLC control module.

[0035] A cavity is formed on the fixed bracket 61, which runs through from top to bottom. The front and rear opposite inner walls in the middle of the cavity are fixedly mounted with symmetrically arranged second bearings 64. A connecting rod 65 is connected and installed between the two second bearings 64. The connecting rod 65 is arranged along the front and rear directions of the conveyor steel belt 3, and can rotate with the center line of the two second bearings 64 as the central axis. A movable plate frame 66 is fixedly installed on the connecting rod 65, and the connecting rod 65 is located in the middle of the movable plate frame 66. The movable plate frame 66 is arranged along the left and right directions of the conveyor steel belt 3, and forms a lever-type rotatable structure with the connecting rod 65 as the central fulcrum. Vertical bearings 68 are respectively installed at the bottom of the left and right ends of the movable plate frame 66, and a correction roller 69 is installed between the two vertical bearings 68. The length of the correction roller 69 is not less than the width of the conveyor steel belt 3. The deviation correction roller 69 is located above the lower section steel belt 32, and the movable plate frame 66 can be lever-shaped and rotated with the connecting rod 65 as the central fulcrum, thereby driving the deviation correction roller 69 to press down on the left or right surface of the conveyor steel belt 3, thereby correcting the conveyor steel belt 3.

[0036] A cylinder 67 is also fixedly mounted on the fixed bracket 61. The output end of the cylinder 67 is fixedly connected to the left or right end of the movable plate frame 66. In this embodiment, the output end of the cylinder 67 is located on the side close to the collision sensing array group "R", that is, it is fixedly connected to the right end of the movable plate frame 66. The cylinder 67 can drive the deviation correction roller 69 to press down to the left or right side. The cylinder 67 is connected to the PLC control module by telecommunication, and the deviation correction roller 69 can be controlled by the PLC control module to press down to the left or right surface of the conveyor steel belt.

[0037] The deviation correction device 6 is provided with a signal sensor 8 matched with the collision sensor 55 and the position sensor 56. The collision sensor 55, the position sensor 56 and the signal sensor 8 are respectively connected to the PLC control module by signal.

[0038] The working principle of this embodiment is:

[0039] When the conveyor steel belt 3 deviates in the left and right directions, it will first touch the collision sensor 5. Especially for the conveyor steel belt 3 with a longer length, the deviation amplitude of a certain section is the largest. In this embodiment, the upper section steel belt 31 collides with the collision sensor 5. When multiple collision sensors 5 are collided, the data of the collision force will be transmitted to the PLC control module. On the one hand, the PLC control module receives the collision signal and controls the drive motor 4 to stop or reduce the speed, so that the conveyor steel belt 3 stops or slows down. On the other hand, the PLC control module analyzes the data of multiple collision sensors 5, and specifically locates the position where the conveyor steel belt 3 deviates the most, and starts the servo motor 71 to operate the deviation correction device 6; through the position sensor 56 positioning, the signal receiver 8 receives the corresponding position signal, so that the deviation correction device 6 runs quickly to the corresponding position; then the cylinder 67 is started to perform deviation correction.

[0040] For example: Figure 6 and 7For example, when the collision sensing element 5 at the "L2" position is subjected to the maximum collision force, the upper section steel belt 31 of the conveyor steel belt 3 deviates toward the "L" side of the collision sensing array group, and at the same time, the lower section steel belt 32 deviates toward the "R" side of the collision sensing array group, and the maximum deviation amplitude is approximately located near the "L2" position. When the PLC control module receives the signal, it starts the servo motor 7, so that the correction device 6 moves as a whole to the vicinity of the "L2" position. Since the cylinder 67 of this embodiment is set near the "R" side of the collision sensing array group, the action of the cylinder 67 should be to lift up so that the correction roller 69 applies pressure near the "L2" position. Due to the extrusion deformation of the correction roller 69, the tension of the left steel belt of the conveyor steel belt 3 is greater than the tension of the right side, which causes the conveyor steel belt 3 to move to the right during operation. Similarly, when the conveyor steel belt 32 deviates in the opposite direction, the cylinder 67 presses down, and the conveyor steel belt 3 deviates in the opposite direction of the pressed direction.
