[0034] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0035] The present application provides a conveying belt replacement device, comprising: an unwinder 100, a curling machine 200, a conveying belt clamping plate 300 and a conveying belt connecting mechanism 400; the unwinder 100 and the curling machine 200 are located on both sides of the conveying belt connecting mechanism 400; the conveying belt connecting mechanism 400 conveys one end of the old belt to the vicinity of the unwinder 100, clamps the new belt with the old belt using the belt clamping plate, and conveys the other end of the old belt to the curling machine 200, and the old belt is wound up by the curling machine 200.

[0036] In this way, the old belt and the new belt, which originally operate independently, are connected by the conveying belt connecting mechanism 400, so that they can be separated from the conveying belt 10 and rotated, so that the old belt can be replaced by the new belt, and the replacement of the old belt and the new belt can be realized.

[0037] In an embodiment, the conveying belt clamping plate 300 is composed of two steel plates, and both ends have screw holes.

[0038] In an embodiment, the conveying belt replacement device further comprises an outer pinch roller 500 installed on the outer side of the conveying belt connecting mechanism 400 for clamping and fixing the belt.

[0039] In an embodiment, the conveying belt connecting mechanism 400 comprises a three-dimensional frame 410, three belt transmission chain plates 420, a rotating roller 430 and a guide plate 440; the three belt transmission chain plates 420 are installed in sequence below the three-dimensional frame 410, and the belt transmission chain plates 420 on both sides can be rotated to a vertical state by the rotating roller 430; the guide plate 440 is installed on both sides of the three-dimensional frame 410. The conveying belt connecting mechanism 400 further comprises an inner pinch roller 450 installed at one end of the belt transmission chain plates 420 on both sides. The conveying belt replacement device further comprises two guide tables 600, one guide table 600 is installed between the unwinder 100 and the conveying belt connecting mechanism 400, and the other guide table 600 is installed between the curling machine 200 and the conveying belt connecting mechanism 400.

[0040] Exemplary, the uncoiler 100 and coiler 200 are symmetrically located on both sides of the three-dimensional frame 410, the conveying belt connecting device is located in the middle of the three-dimensional frame 410, and the conveying belt is connected by the inner pinch roller 450 at both ends. The conveying belt connecting device and the uncoiler 100 are connected by the guide table 600, thereby forming a whole.

[0041] In an embodiment, the conveying belt replacement device further comprises a cutting machine; the cutting machine is used to cut the old belt.

[0042] After cutting the old belt, one end of the old belt is fixed with the new belt using the conveying belt clamping plate 300.

[0044] The laser positioning device requires accurate positioning of the conveying belt, and the running accuracy is high. Therefore, the pinch roller motor, the uncoiler 100 and the coiler 200 motor all adopt servo motors. Such motors control the running accuracy through pulse signals, accurately control physical quantities such as speed and angle, and respond quickly, which can greatly meet the actual needs of the device. When there is no pulse signal input, the motor itself will be in a self-locking state. Even if external force is applied, it will remain in a self-locking state if the torque is less than the rated torque. When the device is working, the safety factor is greatly increased.

[0045] In an embodiment, the uncoiler 100 comprises a winding drum 110, a guide belt 120 and a movable pressure roller 130; the guide belt 120 is located below the winding drum 110 and can move back and forth; and the movable pressure roller 130 is located obliquely above the winding drum 110 and can be pressed towards the center of the winding drum 110 as the unwinding diameter of the conveying belt decreases.

[0046] Exemplary, the guide belt 120 in the tight state is in a straight line type and is made of a magnetic material.

[0048] Exemplary, the movable pressure roller 130 is connected with a hydraulic rod through a bearing seat, and can be pressed towards the center of the winding drum 110 as the unwinding diameter of the conveying belt decreases.

[0049] Exemplary, the winding drum 110 adopts a four-piece structure of the winding drum 110 expansion and contraction mechanism, and the inclined wedge expansion and contraction type is driven by a hydraulic driven mandrel to drive the inclined wedge and sleeve to move axially, so as to expand and contract the winding drum 110 and ensure the tension of the belt.

[0050] In an embodiment, the coiler 200 has the same structure as the uncoiler 100.

[0051] In an embodiment, the conveyor belt replacement device further comprises an outer frame 800, the unwinder 100, the coiler 200, the conveying belt clamping plate 300 and the conveying belt connecting mechanism 400 are installed inside the outer frame 800.

[0052] All the roller devices of the device are controlled by motors, and the control end is operated by a computer system, so that more manpower is saved, and only electric energy is required, and a large-capacity battery can be arranged on the device or wired power supply can be adopted.

[0053] The specific use mode is as follows: the device is installed at the position of the conveyor belt 10 where the belt needs to be replaced, the old belt is clamped by the inner pinch roller 450 in the conveying belt connecting device to prevent it from falling off during cutting. In the conveying belt connecting device, a cutting machine is used to cut the old belt. One end of the old belt on the left side is rotated to a vertical state, and the old belt is conveyed to the guide table 600 on one side of the unwinder 100. Then, the new belt is clamped and connected with the old belt by using the conveying belt clamping plate 300 and the matched bolts. The unwinder 100 is rotated, the guide belt 120 and the movable pressure roller 130 are operated to convey the old belt to the right, at the same time, one end of the old belt on the right side is rotated to a vertical state, and the old belt is wound on the coiler 200 through the outer pinch roller 500 and the guide plate 440. The auxiliary devices of the unwinder 100 and the coiler 200, the guide belt 120 and the pressure roller of the unwinder 100 move towards the center of the winding drum 110 as the belt gradually decreases, and the guide belt 120 and the pressure roller of the coiler 200 move away from the center of the winding drum 110 as the belt gradually increases, so that the belt is tightly pressed during replacement, the braking torque is increased, and normal unwinding and coiling are facilitated.

[0054] When the new belt is gradually separated from the guide plate table, the inner pinch roller 450 clamps the belt, the turning roller is rotated to a horizontal state, the outer pinch roller 500 pushes the new belt to below the curing machine 700, and the new belt is pushed to the specified position through the laser positioner. When the old belt is coiled on the coiler, part of the old belt is located on the guide plate table, the inner pinch roller 450 clamps the belt, the conveying belt clamping plate 300 is removed, the turning roller is rotated to a horizontal state, the outer pinch roller 500 pushes the new belt to below the curing machine 700, and the new belt is pushed to the specified position through the laser positioner.

[0055] After the new belt is located on the conveying belt 10, the curing machine 700 above is pressed downward to connect the vulcanized belt, and after successful vulcanization, the new belt replacement is successful.
