[0002] Belt drive can produce continuous rotational motion, transmitting force from one transmission wheel to another. However, in the process of transmission, the traditional belt is easily offset and slides on the driving spindle due to the rotational connection between the belt and the driving spindle during operation, which can easily cause detachment and increase the subsequent labor intensity of the staff.

[0003] The utility model with publication number CN 214166382 U discloses a belt anti-deviation mechanism, including a driving spindle, a belt, two sets of adjustment components and two sets of guide components, the belt is correspondingly sleeved on the outside of the driving spindle, the two sets of adjustment components are correspondingly installed on both sides of the driving spindle, the two sets of guide components are correspondingly sleeved on both sides of the driving spindle, and the output ends of the two sets of guide components are in contact with both sides of the belt.

[0004] As shown in the above-mentioned utility model, the existing belt anti-deviation mechanism uses a positioning ring and a rotating ring to block both sides of the belt to avoid the belt from falling off during operation. However, this method is generally suitable for transport belts with shorter strokes. For belts with longer strokes, this method cannot prevent the middle belt from deviating. Moreover, the existing belt anti-deviation structure is not equipped with a monitoring and alarm mechanism, so that the staff needs to patrol back and forth to determine the location of the fault and the processing cycle is long, which seriously affects the work efficiency.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides two technical solutions:

[0027] Figure 1-Figure 3 The first embodiment is shown: a belt anti-deviation structure with monitoring and early warning functions, comprising:

[0028] The fixing seat 1 is set to an L-shaped structure. Four equally spaced guide grooves 12 are opened at the upper end of the fixing seat 1. A through groove 13 is opened in the middle of the upper end of the fixing seat 1. A receiving plate 14 is arranged below one side opening of the through groove 13. One end of the receiving plate 14 is fixedly connected to the fixing seat 1. A dovetail groove 15 is opened on the upper surface of the receiving plate 14. One end of the dovetail groove 15 extends into the through groove 13. A screw groove 16 is arranged above one side opening of the through groove 13. The screw groove 16 is opened on the fixing seat 1;

[0029] The anti-deviation warning component 2 is connected to the fixed seat 1 through the guide groove 12. The anti-deviation warning component 2 includes a mounting frame 21, and a guide wheel 22 is connected to the mounting frame 21 through a movable shaft. The guide wheel 22 fits with the edge of the belt and does not hinder the operation of the belt when fitting. The anti-deviation warning component 2 includes a mounting frame 21, and the mounting frame 21 is arranged as a horizontal U-shaped structure. A plurality of guide wheels 22 are arranged, and the plurality of guide wheels 22 are horizontally distributed in the inner cavity of the mounting frame 21 at equal intervals. A guide rod 23 is fixed at the four corners of one side of the mounting frame 21, and one end of the guide rod 23 passes through the guide groove 12 and is fixed with a limiting plate. The guide rod 23 and the guide groove 12 cooperate to play a guiding role, so that the mounting frame 21 maintains horizontal linear movement. A spring 24 is sleeved on the outer side of the guide rod 23, and the spring 24 is located between the fixed seat 1 and the mounting frame 21. The setting of the spring 24 plays a slight preliminary correction role when the belt deviates.

[0030] The alarm device 4 is fixed at the middle of the top end of the fixing seat 1 and is used to sound an alarm when the belt is prevented from deflecting.

[0031] Figure 1 and Figure 4A second embodiment is shown, which is different from the first embodiment in that it includes an anti-bias adjustment component 3, which is arranged at the middle of the upper end of the fixed seat 1 and is used for anti-bias adjustment of the belt. The anti-bias adjustment component 3 includes a movable plate 31, one end of the movable plate 31 is connected with the through groove 13, and a dovetail slider 32 is fixed to the lower surface of the movable plate 31, and the dovetail slider 32 is located in the dovetail slide groove 15. The dovetail slider 32 and the dovetail slide groove 15 cooperate to play a limiting role, so that the movable plate 31 maintains horizontal linear movement and will not separate from the receiving plate 14. A motor 33 is fixed to one end of the upper surface of the movable plate 31, and a screw rod 34 is fixed to the output end of the motor 33. One end of the screw rod 34 is connected with the screw groove 16, and the motor 33 drives the screw rod 34 to rotate, and the screw rod 34 cooperates with the screw groove 16 to drive the movable plate 31 to move. A mounting plate 35 is fixed to the other end of the belt, one end of the screw rod 34 is movably connected to one side of the mounting plate 35 through a bearing, a rubber pad 36 is bonded to the lower end of the other side of the mounting plate 35, the setting of the rubber pad 36 prevents the mounting plate 35 from rigidly contacting the mounting frame 21, and distance sensors 37 are fixed on both sides of the upper end of one side of the mounting plate 35, through holes 38 are opened on both sides of the upper end of one side of the mounting plate 35, and the probe of the distance sensor 37 is located in the through hole 38. The distance sensor 37 can monitor the distance between the mounting plate 35 and the mounting frame 21 in real time through the through hole 38. When the belt deviates greatly, it will drive the mounting frame 21 to move, shortening the distance between the mounting frame 21 and the mounting plate 35. When the distance between the mounting frame 21 and the mounting plate 35 is less than a preset threshold, the distance sensor 37 transmits data to an external PLC controller, and the PLC controller controls the motor 33 to start.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0033] The guide wheel 22 on the mounting frame 21 contacts the normally running belt under the action of the spring 24. When the belt deviates slightly, the reaction force generated by the spring 24 plays a corrective role. When the belt deviates seriously, the guide wheel 22 drives the mounting frame 21 to move, shortening the distance between the mounting frame 21 and the mounting plate 35. At this time, the distance sensor 37 monitors the distance between the mounting frame 21 and the mounting plate 35 in real time. When the distance between the mounting frame 21 and the mounting plate 35 is less than the preset threshold, the distance sensor 37 transmits abnormal data to the external PLC controller. The LC controller controls the alarm 4 to sound an alarm to remind the staff to come quickly. At the same time, the PLC controller controls the motor 33 to start, and the motor 33 drives the screw rod 34 to rotate. The screw rod 34 cooperates with the screw groove 16 to drive the motor 33 to move, and then drives the movable plate 31 to move. The movable plate 31 drives the mounting plate 35 to move until the rubber pad 36 on the mounting plate 35 contacts the mounting frame 21, and then drives the mounting frame 21 to move until the belt is moved to its original position. Then the PLC controller controls the motor 33 to reverse, driving the mounting plate 35 to move to its original position.
