Further, the sensing device is a photoelectric switch.

Further, the drive roller drive device includes a reducer and a motor, and the motor drives the drive roller to rotate through the reducer.

Further, an angle wrapping roller is also provided on the right side of the driving roller.

The beneficial effects of the utility model are:

The utility model is provided with a tensioning device and a deviation correcting device. The tensioning device uses a tensioning cylinder to drive the driven roller to move left and right. When the conveyor belt is elongated and loose, the tensioning cylinder is always at a constant pressure value. Once the conveyor belt becomes loose, the pressure from the driven roller to the conveyor belt will decrease, and this is the tension cylinder will push the driven roller to move to the left, so that the conveyor belt is always in a tensioned state, avoiding the conveyor belt Loosening and slipping makes the conveyor belt stop moving; when the deviation correction device detects the deviation of the conveyor belt through the photoelectric switch, according to the direction of deviation, the deviation correction cylinder is used to drive the deviation correction roller to form a certain angle and press the conveyor belt to move to the other side. After the conveyor belt returns to the original normal conveying position, the photoelectric switch will feed back a signal to the correction cylinder to stop moving. By installing deviation correcting devices on the driving roller and the driven roller respectively, the conveyor belt is guaranteed to run along the normal position of the center line; avoiding the deviation of the conveyor belt and interrupting normal production. The utility model solves the problems of elongation and deviation of the conveyor belt of the oven during the conveying process, thus ensuring the normal operation and continuous normal production of the conveyor belt.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 to 3, an oven conveying device includes a first workbench 1, a second workbench 2, a driving roller 3, a driven roller 4, a conveyor belt 5 and a driving roller driving device 9. One end of the conveyor belt 5 is installed on the driving roller, and the other end is installed on the driven roller 4. It also includes a tensioning device 6 and a deviation correction device 7. The tensioning device 6 is arranged on the second workbench 2 Above, the tensioning device 6 includes a guide rail 61 installed on the second workbench 2, a first moving seat 62 mounted on the guide rail 61 that can slide left and right, and a tensioner that can drive the first moving seat 62 to move left and right. Cylinder 63, the driven roller 4 is rotatably installed on the first moving seat 62, the right side of the first moving seat 62 is also provided with a fixed seat 64, and one end of the tensioning cylinder 63 is fixed on the fixed seat 64, the other end of the tensioning cylinder 63 is connected with the first moving seat 62, the tensioning device 6 is provided with two groups, and is respectively arranged on both sides of the conveyor belt 5, when the conveyor belt 5 is heated and stretched When there is no tension after long loosening, the driven roller 4 is driven to move to the left by two sets of tensioning cylinders 63 of the tensioning device, so that the driven roller 4 maintains a certain tension so that the conveyor belt 5 is always at the tense state. The tensioning device 6 has the function of tensioning first and automatically relaxing when the equipment stops running before driving the equipment, mainly for protecting the service life of the conveyor belt.

The deviation correcting devices 7 are respectively arranged on the first workbench 1 and the second workbench 2, and can respectively correct the upper side and the lower side of the conveyor belt 5 respectively. The deviation correction device 7 includes a second moving seat 71, a deviation correction roller 72, a deviation correction cylinder 73 and an induction device 74, and the second movement seat 71 and the induction device 74 are respectively arranged on both sides of the conveyor belt 5, and the deviation correction roller 72 Installed on the two second moving seats 71, the deviation correcting cylinder 73 is arranged on one side of the conveyor belt 5, and the deviation correcting cylinder 73 can drive the second moving seat 71 to move left and right, thereby driving one end of the deviation correcting roller 72 to perform Move left and right. The sensing device 74 is a photoelectric switch.

Keep a certain distance between the conveyor belt 5 and the photoelectric switches on both sides. When the conveyor belt 5 deviates to one side, the photoelectric switch on one side detects that the conveyor belt 5 deviates to one side, and then immediately feeds back information to the deviation correction cylinder 73 to correct the deviation.
