Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building material production, in particular to an adjustable limiting power roller group for a concrete self-insulating building block conveyor line. Background Art
[0002] This application is mainly used in aerated concrete production lines, and is used for the driven transportation and positioning of the mold box trolley or the side panels of the blank in the curing section of the concrete self-insulating block casting. When transporting the side panels with the blank, the roller group is composed entirely of powered rollers, and when transporting the empty bottom plate, it is composed of powered and unpowered rollers. In actual production, due to the long transportation process and the large difference in transportation load-bearing capacity between those with and without the blank, the load-bearing center and wear position of the transport rollers are complex and uncontrollable, so there is also the problem of deviation during the transportation of the side panels, which poses a great safety threat and correction operation cost to the operators.
[0003] There are two main measures to prevent deviation from the conveyor belt field: one is to use anti-deviation transmission rollers (transmission drums), for example, disc-shaped baffles are fixed on the edges of both sides of the transmission rollers; the other is to use anti-deviation roller groups, that is, a three-section roller group is used to form a grooved roller group, so that the conveyor belt has an inner groove shape, thereby preventing deviation.
[0004] However, in practice, the above roller settings still have some problems in our company's transport side panels: 1. The disc-shaped baffles are fixed on the edges of both sides of the transmission rollers. Although they can prevent the side panels from running off and falling off to a certain extent, hard collisions will occur during the twisting process, forcing the side panels to be diverted, causing significant wear on the side panels and baffles, seriously affecting the billet forming and the service life of the conveyor line. 2. The improvement of the three-section roller assembly to form a trough-type roller group. Although our company has further improved the groove angle to form a micro-groove setting, which also has the effect of adjusting the deviation to a certain extent, the side panels are flat-plate conveying parts with a large load-bearing capacity. The trough-type roller group still cannot bear the force on the entire plane. The force points are concentrated on the rollers on both sides, causing significant damage to the rollers and side panels. In addition, the transportation is not stable, resulting in loose ingredients and affecting the billet forming. Utility Model Content
[0005] The technical problem to be solved by the utility model is to solve the problem that in the actual production process, our company arranges a three-section roller to form a trough type roller group, which has the function of adjusting the deviation to a certain extent, but the side plate and the trough type roller group cannot be subjected to force in the whole plane, and the force points are concentrated on the rollers on both sides, which causes great damage to the rollers and the side plates, and the transportation is not stable, resulting in loose ingredients and affecting the forming of the blanks. The utility model provides a new concrete self-insulating block conveyor line with adjustable limit power roller group.
[0006] The utility model aims to provide an adjustable limited power roller group for a concrete self-insulating block conveyor line, comprising a driving motor, the driving motor is connected to a coupling, the coupling is connected to a transmission shaft, the transmission shaft is mounted on a roller group mounting seat, a synchronously rotating roller is arranged in the middle of the transmission shaft, both sides of the synchronously rotating roller are connected to freely rotating movable rollers through bearings, both sides of the movable roller are provided with deflection adjustment wheels, the circumference of the deflection adjustment wheel is provided with adjustment protrusions, the adjustment protrusions are distributed in a non-closed spiral trajectory along the circumference of the deflection adjustment wheel, and the spiral trajectories of the adjustment protrusions of the two deflection adjustment wheels on both sides are mirror-imaged relative to the central axis of the roller group.
[0007] Preferably, the spiral tracks of the adjusting protrusions of the two deflection adjusting wheels are arranged to be inclined toward the inner central axis along the transmission direction of the roller.
[0008] Preferably, a limit plug is provided at each end of the transmission shaft, and the limit plug is passed through the two ends of the transmission shaft.

[0013] Preferably, the spiral tracks of the two adjustment grooves are arranged to be inclined toward the inner central axis along the transmission direction of the roller.

[0015] The utility model realizes linear full-contact power drive in the middle through the synchronous rotating wheel, the force is fully and evenly distributed, the transmission is smooth, the conveying vibration of the blank is small, and the forming is good; the two sides of the synchronous rotating roller are connected to the freely rotating movable rollers through bearings, and the movable roller serves as a first-level adjusting wheel. When the side plate is slightly offset, the movable wheel deviated to one side will increase the load, thereby increasing the rotation speed of the movable wheel on this side to be almost synchronized with the synchronous rotating wheel, while the movable wheel on the other side is subjected to less or no force, and tends to have a slower rotation speed, thereby weakening the conveying drive on the other side, and then performing the first-level deviation correction on the side plate; deviation adjustment wheels are arranged on both sides of the movable roller, and adjustment protrusions are arranged on the circumference of the deviation adjustment wheel. The adjustment protrusions are distributed in a non-closed spiral trajectory along the circumference of the deviation adjustment wheel, and the spiral trajectories of the adjustment protrusions of the two deviation adjustment wheels on both sides are mirror-set relative to the central axis of the roller group, and the force trajectory of the load-bearing object on the deviation adjustment wheel also runs in a non-closed spiral trajectory as the adjusting protrusion tilts inward, thereby exerting inward symmetrical force on both sides of the side plate, further effectively suppressing the deviation of the side plate.

The spiral tracks of the adjustment protrusions 601 of the two deflection adjustment wheels 6 are tilted toward the inner central axis along the roller transmission direction.
[0021] The present embodiment realizes full contact power drive in the middle part through synchronously rotating rollers, the force is fully and evenly distributed, the transmission is smooth, the conveying vibration of the blanks is small, and the forming is good; the two sides of the synchronously rotating rollers are connected to the freely rotating movable rollers through bearings, and the movable rollers serve as the first-level adjusting wheels. When the side plate is slightly offset, the movable wheel deviated to one side will increase the load, thereby increasing the rotation speed of the movable wheel on this side to be almost synchronized with the synchronously rotating wheel, while the movable wheel on the other side is subjected to less or no force, and tends to have a slower rotation speed, thereby weakening the conveying drive on the other side, and then performing the first-level deviation correction on the side plate; deviation adjustment wheels are arranged on both sides of the movable roller, and adjustment protrusions are arranged on the circumference of the deviation adjustment wheel. The adjustment protrusions are distributed along the circumference of the deviation adjustment wheel in a non-closed spiral trajectory, and the spiral trajectories of the adjustment protrusions of the two deviation adjustment wheels on both sides are mirror-set relative to the central axis of the roller group, and the force trajectory of the load-bearing object on the deviation adjustment wheel also runs in a non-closed spiral trajectory as the adjustment protrusion tilts inward, thereby exerting inward symmetrical forces on both sides of the side plate, further effectively suppressing the deviation of the side plate.
[0022] In other specific embodiments, a limiting plug 7 is provided at each end of the transmission shaft 3, and the limiting plug 7 is passed through the two ends of the transmission shaft 3. The limiting plug 7 is connected to the transmission shaft 3 through a bearing. The limiting plug 7 includes a limiting end disk portion 701 and a limiting cone portion 702, the bottom surface of the limiting cone portion 702 is connected to the limiting end disk portion 701, the limiting end disk portion 701 is arranged on the outside, and the limiting cone portion 702 is arranged on the inside. An adjustment groove 703 is provided on the conical surface of the limiting cone portion 702, and the adjustment groove 703 is distributed along the conical surface in a non-closed spiral trajectory, and the adjustment grooves 703 on both sides are symmetrically arranged relative to the central axis of the roller group, and the spiral trajectory of the adjustment groove 703 is inclined along the transmission direction of the roller toward the inner central axis. The present embodiment sets a three-level deviation correction mechanism. When the side panel is offset to a large extent, such as during the return of the side panel, if more blanks are adhered to one side of the side panel, resulting in a large difference in the weight of the side panel, it will cause serious lateral deviation in the conveying diagram. In this case, the side panel may break through the first and second level deviation correction measures and further deflect to the position of the limit plugs at both ends. Through the setting of the present embodiment, when the side panel deflects to the position of the limit plug, it will not directly cut off the lateral deflection force of the side panel at one time like the traditional disc-type baffle, thereby causing a large impact force and damage. Instead, the lateral deflection force of the side panel is slowly weakened through the conical guide and the non-closed-loop spiral groove guide of the present application. On the one hand, hard collisions are avoided and damage to the side panel and the blocking member is reduced. On the other hand, the third level deviation correction can be effectively performed in a process-type manner, which once again assists the adjustable limit-type conveying of the side panel in the concrete self-insulating block conveying line, which helps to ensure smooth transportation, safety and efficiency.
