[0002] A tape machine is a machine used to produce tape or similar tape products. Due to the differences in performance of different types of tape products, there are many types of tape machines. Depending on the tape's base material, the properties of the coating liquid, and processing requirements, the structure and configuration of the tape machine often vary greatly. The production process of tape is to apply glue to the base material, so it is usually called a coating machine in the industry.

[0003] Whether the existing belt conveyors use proximity switches or stall switches to detect the belt speed, when they fail, it is impossible to truly determine on the host computer screen whether the belt conveyor is actually slipping or stuck. This will cause trouble to the operator and confusion to the maintenance personnel, requiring the machine to be stopped to check the actual status of the belt, causing economic losses to normal production and affecting the normal production of the blast furnace.

[0028] Specifically, the outer surfaces of the driving wheel 2 and the driven wheel 3 are provided with a transmission belt 6, the driving wheel 2 and the driven wheel 3 are connected to each other through the transmission belt 6, and the driving wheel 2 and the driven wheel 3 are movably connected to the bearing seat 4 through the connecting shaft 5.

[0029] In this embodiment, the detection mechanism can detect whether the operation of the driving wheel 2 and the driven wheel 3 is normal, and prompt to perform maintenance or stop the operation of the belt conveyor according to the detection result.

[0030] like Figure 2 As shown, there are two groups of bearing seats 4, each group of bearing seats 4 has two bearing seats 4 and are symmetrically distributed on the two bases 1, the two groups of bearing seats 4 are respectively located on the left and right sides of the driving wheel 2 and the driven wheel 3, and mounting holes are opened around the top of the bearing seat 4. Bolts that penetrate the bearing seat 4 and extend to the inside of the base 1 are provided in the mounting holes, and the bearing seat 4 is fixedly connected to the base 1 through the mounting holes and the bolts.

[0031] In this embodiment, the provision of the bolts facilitates the installation and disassembly of the bearing seat 4 .

[0032] like Figure 2-3 As shown, there are two stop irons 7, which are respectively arranged on the driving wheel 2 and the driven wheel 3. There are two groups of proximity switches 8, each group of proximity switches 8 has two proximity switches 8, which are symmetrically distributed on the front and back sides of the two left bearing seats 4, and the four proximity switches 8 are all located on the same horizontal line.

[0033] In this embodiment, a plurality of proximity switches 8 are provided so that the detection results of the plurality of proximity switches 8 can be mutually verified, thereby preventing an accidental shutdown command due to a failure of the proximity switch 8 as much as possible.

[0034] like Figure 2-3 As shown, a driving motor 9 is arranged on the right side of the right base 1, and the output shaft of the driving motor 9 extends to the inside of the corresponding bearing seat 4 and is connected to the connecting shaft 5.

[0035] In this embodiment, the driving motor 9 can drive the driving wheel 2 to operate, and the mounting seat 10 can fix the driving motor 9 .

[0036] The method of using the utility model is as follows:

[0037] The real-time speed detection of the driving wheel 2 is realized by the corresponding gear iron 7 and the proximity switch 8. At the same time, the address code of the driving wheel 2 is numbered in the PLC program so as to determine the specific location of the problem in real time.

The counting range value of the proximity switch 8 when the driving wheel 2 is operating normally is calculated according to the number comparison. Similarly, the counting range value of the proximity switch 8 when the driven wheel 3 is operating normally is calculated. If the values ​​detected by the two proximity switches 8 corresponding to the driving wheel 2 are both within the normal range at the same time, it means that the driving wheel 2 is operating normally.

The proximity switches 8 corresponding to the driving wheel 2 and the driven wheel 3 will verify each other. When the value obtained by any proximity switch 8 in one group is different from the normal range count value, a warning reminder is output, requiring maintenance personnel to detect whether the proximity switch 8 is faulty, but no command to stop the belt conveyor will be issued. When the values ​​detected by all bearing seats 4 are not within the normal counting range, the PLC will issue a command to stop the belt conveyor.

[0038] The PLC program judgment logic is:

[0039] 1. One or two proximity switches 8 corresponding to the driving wheel 2 are both within the normal counting range, and one or two proximity switches 8 corresponding to the driven wheel 3 are both within the normal counting range, that is, the belt conveyor is operating normally, and the host computer displays the normal operating prompt of the driving and driven wheels with the corresponding address numbers;

[0040] 2. One or two proximity switches 8 corresponding to the driving wheel 2 are within the normal counting range, and the count value of one or two proximity switches 8 corresponding to the driven wheel 3 is greater than 0 and less than the normal counting range, that is, the driven wheel 3 slips, and the PLC outputs a stop belt conveyor instruction, and displays a slip alarm prompt of the driven wheel 3 corresponding to the address number on the host computer;

[0041] 3. One or two proximity switches 8 corresponding to the driving wheel 2 are within the normal counting range, and the count value of one or two proximity switches 8 corresponding to the driven wheel 3 is equal to 0, that is, the driving wheel 2 slips, the PLC outputs the command to stop the belt conveyor, and displays the driving wheel 2 slip alarm prompt corresponding to the address number on the host computer;

[0042] 4. The count values ​​of the two proximity switches 8 corresponding to the driving wheel 2 are equal to 0, and the count values ​​of the two proximity switches 8 corresponding to the driven wheel 3 are equal to 0, that is, the driving wheel 2 and the driven wheel 3 are blocked. The PLC outputs the command to stop the tape machine and displays the blocking alarm prompt of the driving wheel 2 and the driven wheel 3 with the corresponding address number on the host computer.
