Description

Technical Field

[0001] This application belongs to the field of conveyor belt equipment, and specifically relates to an adjustment device for the reversing roller of a belt conveyor. Background Technology

[0002] Conveyor belts are commonly used to transport materials needed in industrial production. During continuous operation, factors such as temperature can cause changes in the hardness of the conveyor belt, thus affecting its tension. Furthermore, during operation, factors such as insecure installation, vibration, load variations, and impact from falling materials can also cause changes in belt tension, leading to belt misalignment. This prevents the conveyor belt from transporting materials normally and disrupts production. Therefore, it is necessary to adjust the conveyor belt tension during production to correct belt misalignment. Utility Model Content

[0003] The purpose of this invention is to provide an adjustment device for the reversing roller of a belt conveyor, which can meet the need for rapid adjustment of the tension of the conveyor belt during the production process.

[0004] To achieve the above objectives, this application provides the following technical solution: an adjustment device for a reversing roller of a belt conveyor, characterized in that: both ends of the reversing roller are rotatably supported by bearing seats, the bearing seats are located on the outer side of the frame support plate, the frame support plate has a strip hole in the long axis direction perpendicular to the core of the reversing roller, the bolt on the bearing seat passes through the strip hole and is connected to the slider, the slider is located on the inner side of the frame support plate and is linearly displaced in the direction defined by the guide rail and the displacement direction is perpendicular to the core of the reversing roller, the nut hole on the slider is connected to the adjusting bolt, the adjusting bolt passes through the through hole opened on the limiting baffle provided at the end of the guide rail, and the bolt head of the adjusting bolt is located on the plate surface of the limiting baffle on the side away from the guide rail.

[0005] The above technical solution uses a rotating adjusting bolt to move the slider within the guide rail, which in turn moves the bearing seat connected to the slider by the bolt. When the bearing seat moves to the point where the conveyor belt surface tightens, the rotating adjusting bolt is stopped and the bolt on the bearing seat is tightened to determine the position of the reversing roller. This achieves rapid adjustment of the reversing roller of the belt conveyor with low operation difficulty. Attached Figure Description

[0011] This application provides an adjustment device for the reversing roller of a belt conveyor, combined with Figure 1 , 2 As shown in Figures 3, 4, and 5, the two ends of the reversing roller 10 are rotatably supported by bearing seats 20. The bearing seats 20 are located on the outer side of the frame support plate 30. The frame support plate 30 has a strip hole 31 with its long diameter direction perpendicular to the roller core of the reversing roller 10. The bolt 21 on the bearing seat 20 passes through the strip hole 31 and is connected to the slider 40. The slider 40 is located on the inner side of the frame support plate 30 and is linearly displaced in the direction defined by the guide rail 32, with the displacement direction perpendicular to the roller core of the reversing roller 10. The nut hole on the slider 40 is connected to the adjusting bolt 50. The adjusting bolt 50 passes through the through hole 331 opened on the limiting baffle 33 at the end of the guide rail 32. The bolt head 51 of the adjusting bolt 50 is located on the plate surface of the limiting baffle 33 on the side away from the guide rail 32.

[0012] The so-called inside and outside positional relationship is based on the frame support plate 30 as the boundary. The outside that directly faces the bearing seat 20 is the outside, and the inside that faces the slider 40 is the inside.

[0013] In the above scheme, the bearing housing 20 and the slider 40 are connected by bolts 21 to achieve synchronous displacement. When it is necessary to adjust the belt tension of the belt conveyor, only the position of the reversing roller 10 needs to be adjusted. The power roller of the belt conveyor is fixed because it is connected to the motor.

[0014] Tighten bolt 21 to prevent excessive pressure on the inner and outer surfaces of the bearing housing 20, slider 40 and frame support plate 30. Then tighten adjusting bolt 50 to drive slider 40 to move linearly and simultaneously drive bearing housing 20 to move in the same direction. When bearing housing 20 is moved to the belt A in a suitable tension state, tighten bolt 21 to ensure that bearing housing 20, slider 40 and inner and outer surfaces of frame support plate 30 are pressed and fixed.

[0015] like Figure 5As shown, the through-holes 31 on the frame support plate 30 are vertically oriented, and two slotted slots 31 are spaced apart, with their major diameters collinear. The vertical orientation of the slots 31 ensures that the bolts 21 connecting the bearing housing 20 and the slider 40 are vertically arranged, providing a horizontal support surface for the bearing housing 20. This horizontal support surface supports the bearing housing 20 without requiring the bolts 21 to bear the weight of the belt conveyor. The bolts 21 bear the tensile force when fixing the bearing housing 20 and the slider 40, thus avoiding shear force.

[0016] To provide a horizontal support surface for the bearing housing 20, this application provides two preferred options:

[0017] One is: such as Figure 4A As shown, the slider 40 is a concave block with its opening facing downwards. The nut hole on the slider 40 is opened on the end plate 42, which is placed downwards on one side of the top plate 41. The end plate 42 and the top plate 41 of the slider 40 are engaged with the limiting surface on the guide rail 32.

[0018] Secondly: such as Figure 4B As shown, the slider 40 is an angular block, and the nut hole on the slider 40 is opened on the end plate 42 that is placed downward on one side of the top plate 41. The end plate 42 and the top plate 41 of the slider 40 are engaged with the limiting surface on the guide rail 32.

[0019] In the above schemes one and two, the only difference is the shape of the slider 40. This allows for selection based on the available raw materials and spare parts. The purpose is to adjust the position of the bearing seat 20 using the screw-nut-slider mechanism. The adjusting bolt 50 engages with the nut hole on the slider 40, ensuring that the adjusting bolt 50 rotates without axial displacement. Therefore, the bolt head 51 of the adjusting bolt 50 always rests against the outer side of the limit baffle 33, ensuring the compactness of the adjustment structure and avoiding adverse effects on the operator's normal activity space. Furthermore, the machining of the nut hole on the slider 40 is extremely convenient, ensuring the machining accuracy between the threaded core and the mating surface of the slider 40 with the guide rail 32. Conversely, if a threaded hole is opened in the limit baffle 33, the tolerance accuracy between the position of the threaded hole on the limit baffle 33 and the guide rail 32 on the frame support plate 30 is difficult to guarantee because the limit baffle 33 needs to be connected to the frame support plate 30.

[0020] Preferred, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, the frame support plate 30 is an angular profile and has a strip hole 31 on the horizontal plate 34. The vertical plate 35 is located on the outer side of the horizontal plate 34 and extends downward.

[0021] The use of angled profile frame support plate 30 facilitates the installation of a horizontal support surface to support the bearing seat 20. The strip hole 31 on the horizontal plate 34 provides a reliable support surface to support the bearing seat 20. The vertical plate 35 extends downward to facilitate connection with the frame.

[0022] As shown in Figures 4 and 5, the guide rail 32 is a shallow groove on the lower horizontal surface of the frame support plate 30.

[0023] The guide rail 32 needs to be kept in a horizontal position to ensure that the slider 40 maintains a horizontal displacement during adjustment. This is to ensure that when the bearing seat 20 is in a horizontal displacement, the amount of displacement required by the slider 40 to achieve synchronous displacement with the bearing seat 20 is basically the same as that of the bearing seat 20.

[0024] As shown in Figures 4 and 5, the guide rail 32 is a shallow groove located on the lower surface of the horizontal groove bottom plate of the frame support plate 30. As previously described, the guide rail 32 maintains a horizontal orientation to ensure that the slider 40 maintains its horizontal displacement during the adjustment process.

[0025] like Figure 3 As shown in Figures 4 and 5, the limiting baffle 33 is bolted to the end face of the channel profile that constitutes the frame support plate 30. This makes it easy to keep the plate surface of the limiting baffle 33 perpendicular to the direction of the guide rail 32, which is beneficial to ensure that the bolt head 51 of the adjusting bolt 50 is always in contact with the outer plate surface of the limiting baffle 33, avoiding the adjusting bolt 50 from being subjected to bending moment and keeping it in an ideal tensile stress state.
