The directional terms used are for better and clearer explanation and understanding of the present invention, rather than indicating or implying the orientation that the present invention must have, and therefore cannot be understood as limitations on the present invention.

[0020] The utility model is implemented as follows Figures 1 to 4As shown in the figure, a conveyor belt counting device includes a bearing cover 1 for covering the conveyor belt roller bearing. The conveyor belt is any existing belt conveyor, which is mainly composed of a conveyor belt, a driving component, a roller, etc. The conveyor belt is usually made of a composite of multiple layers of fiber fabric and rubber layers and can withstand heavy pressure and impact; the driving component usually adopts a transmission mechanism such as a motor and a reducer to provide power drive for the conveyor belt; the roller is a roller composed of two bearings and a cylindrical metal tube, and is usually divided into different types such as a main roller connected to a motor and a supporting roller connected to the main roller. When the counting device is used, the bearing cover 1 of the counting device is installed at the position corresponding to the bearing of the main roller, such as the bearing mounting seat for installing the main roller bearing, or the position on the support of the conveyor belt opposite to the main roller bearing. After the bearing cover 1 is installed, the bearing cover 1 covers the bearing of the conveyor belt roller to prevent it from being exposed to the outside and being damaged by collision. A transparent window 2 is provided on the bearing cover 1. Through the transparent window 2, the operation of the conveyor belt roller can be viewed intuitively, and potential problems of the conveyor belt roller can be discovered in a timely and convenient manner. The transparent window 2 is provided on the bearing cover 1, which means that a through hole is provided on the bearing cover 1, and then a window made of a transparent acrylic plate can be installed in the through hole. In order to facilitate the observation of the end face of the bearing of the conveyor belt roller, the transparent window 2 is It is arranged on the surface of the bearing cover 1 which is perpendicular to the axis of the conveyor roller bearing; the bearing cover 2 is provided with a photoelectric sensor 3 which can emit light to the conveyor roller bearing, such as a distance measuring sensor or a reflective photoelectric sensor for distance monitoring. For the distance measuring sensor, the bearing cover 1 is also provided with a counting piece 4 which rotates synchronously with the conveyor roller bearing and cooperates with the photoelectric sensor 3 for counting. The counting piece 4 is a fan blade which is coaxial with the conveyor roller bearing and moves synchronously. A plurality of blades are arranged on the fan blade at intervals, so that the light emitted by the photoelectric sensor 3 generates different conditions when it is irradiated to the gap between the blades, thereby calculating the number of rotations of the conveyor roller according to the number of times different conditions occur, and then the transmission distance of the conveyor belt is obtained, and the transmission speed of the conveyor belt can also be obtained;For the reflective photoelectric sensor 3, it integrates a transmitter and a receiver and detects objects by receiving light reflected by the detected object. The reflective photoelectric sensor 3 is set on the bearing cover 1, and the light emitted by its transmitter is directed to the bearing of the roller and reflected back to the receiver to complete the detection. At this time, the information detected by the photoelectric sensor 3 is displayed on an external display screen. The external display screen is provided with a microprocessor for processing the information detected by the photoelectric sensor 3 and controlling the display screen. The microprocessor is connected to the photoelectric sensor 3 for collecting counting information and displaying the results on the display screen. In order to reflect the light emitted by the photoelectric sensor 3 back to the photoelectric sensor 3, a counting piece 4 that rotates synchronously with the conveyor roller bearing and cooperates with the photoelectric sensor for counting is also provided in the bearing cover 1. The counting piece 4 adopts a reflective piece that can reflect the light emitted by the photoelectric sensor 3 back to the photoelectric sensor 3. The counting piece 4 is installed on the bearing of the conveyor belt roller or on the rotating shaft of the bearing, so that the counting piece 4 is coaxial with the roller and rotates synchronously. The counting piece 4 is a fan blade that is coaxial with the bearing of the conveyor belt roller and moves synchronously. The fan blade is provided with at least one reflective blade that can reflect the light emitted by the photoelectric sensor 3. That is to say, a plurality of blades are arranged on the fan blade, and at least one of the blades is a reflective blade that can reflect the light emitted by the photoelectric sensor 3 back. For example, three blades are arranged at equal intervals on the fan blade, and one of the three blades is a reflective blade. In this way, when the counting piece 4 rotates coaxially and synchronously with the conveyor belt roller, it can stir the surrounding air to avoid dust accumulation at the bearing of the conveyor belt roller and maintain its normal operation. Such a counting device counts the number of revolutions of the conveyor belt roller. One revolution causes the transmission belt to move the same distance as its circumference. The circumference of the conveyor belt roller is fixed, so the transmission distance of the conveyor belt can be obtained by the number of revolutions, and the transmission speed of the conveyor belt can also be obtained, so as to avoid the counting device being set on both sides of the conveyor belt from being damaged by the collision of the conveyed goods. It is easy to use and more suitable for automatic transmission. Moreover, according to the length of the conveyor belt, the time required for the items placed on the conveyor belt to be transported from one end of the conveyor belt to the other end can be obtained according to the speed of the conveyor belt, and the amount of goods that can be transported in a fixed time can also be obtained. ;

[0021] Further improvements such as Figure 1 , Figure 2 and Figure 4As shown in , an extension arm 10 perpendicular to the outer wall of the bearing cover 1 is extended on the outer wall of the bearing cover 1, and a mounting hole 11 for mounting the bearing cover 1 is provided on the extension arm 10. The bearing cover 1 is mounted on the bearing support by screws passing through the mounting holes 11, which facilitates the installation of the bearing cover 1. The extension arm 10 is two extension arms of a strip structure arranged at both ends of the outer wall of the bearing cover 1 at radial symmetry. It is installed on both sides of the bearing cover 1. The installation structure is firm and reliable, and a mounting hole 11 can be set on it, or the extension arm 10 is an extension arm of a conical structure arranged on the outer wall of the bearing cover 1. The cone is formed by extending one end distance outward from the bearing cover 1 along a certain width and then gradually reducing the width. Three mounting holes 11 are arranged on the extension arm 10. The three mounting holes 11 are arranged in the form of three vertices of a triangle, and then the bearing cover 1 is mounted on the bearing support of the conveyor belt roller by three screws corresponding to the three mounting holes 11. The three-point fixation makes the installation structure of the bearing cover 1 more stable.

[0022] Further improvements such as Figure 1 , Figure 2 and Figure 4As shown in the figure, the bearing cover 1 is a cylindrical column, and the side wall of the bearing cover 1 extends out with a mounting seat 12 for mounting the photoelectric sensor 3; the transparent window 2 is arranged at either end of the bearing cover 1, and the transparent window 2 is arranged at the upper end of the column. At this time, when the extension arm 10 is extended on the column, the extension arm 10 extends from the lower end of the outer side wall of the column, and the extension arm 10 and the transparent window 2 are located on opposite sides of the column, that is, the upper and lower sides. At the same time, the mounting seat 12 is arranged in a square structure, which is also extended from the outer side wall of the column and is located in an adjacent position to the extension arm 10, which facilitates the installation of the photoelectric sensor 3 on the bearing cover 1. After the photoelectric sensor 3 is installed on the mounting seat 12, it is located inside the bearing cover 1, which is convenient for detecting the rotation of the conveyor belt roller. Since the diameters of the conveyor belt rollers are different, in order to meet various needs, a mounting plate 5 that can adjust the distance from the photoelectric sensor 3 to the axial center line of the bearing cover 1 is provided on the mounting seat 12. The photoelectric sensor 3 is mounted on the mounting plate 5. By adjusting the position of the mounting plate 5 on the mounting seat 12, the position of the photoelectric sensor 3 relative to the conveyor belt roller can be adjusted to an appropriate position, that is, the roller will not touch the photoelectric sensor 3 when rotating, and at the same time, the photoelectric sensor 3 can transmit light well with the counting sheet 4.As for the installation of the photoelectric sensor 3 on the mounting seat 12, one is that the mounting seat 12 is a solid structure, a through hole connected to the inside of the bearing cover 1 is set on the mounting seat 12, and the photoelectric sensor 3 is installed in the through hole. Another is that the mounting seat 12 is provided with a notch 13 connected to the inside of the bearing cover 1, such as setting a bearing cover notch on the side wall of the bearing cover 1, and then extending the mounting seat 12 from the outer ends of the two side walls of the bearing cover notch, the mounting seat 12 is an n-type mounting seat, and the mounting plate 5 is a U-shaped structure matched and installed at the notch 13 The mounting plate 5 is composed of a bottom plate and two side plates bent from opposite sides of the bottom plate. At this time, the vertical line of the bottom plate of the mounting plate 5 is perpendicular to the axis line of the bearing cover 1, and the mounting seat 12 is stuck in the opening of the U-shaped structure of the mounting plate 5 in a manner perpendicular to the mounting plate 5. The mounting plate 5 covers the end of the mounting seat 12 away from the center of the bearing cover 1 through its bottom plate. The photoelectric sensor 3 is installed at the bottom of the U-shaped structure on the mounting plate 5, that is, it is installed on the bottom plate of the mounting plate 5. After the photoelectric sensor 3 is installed on the mounting plate 5, the light emitted by it The light can be projected onto the counting sheet in the bearing cover 1 through the notch 13 of the mounting seat 12. The mounting plate 5 is provided with strip through holes 50 on both side walls of the U-shaped structure for adjusting the distance from the photoelectric sensor 3 to the axial center line of the bearing cover 1. The mounting plate 5 is connected to the mounting seat 12 by screws passing through the strip through holes 50; that is, the strip through holes 50 are arranged on the side plates of the mounting plate 5, and the strip through holes 50 extend in a direction perpendicular to the bottom plate of the mounting plate 5. At this time, two identical strip through holes 50 are arranged in parallel and at intervals on the side plates on each side. The strip-shaped through hole 50 prevents the mounting plate 5 from rotating relative to the mounting seat 12, thereby maintaining the stability of the mounting structure. Correspondingly, a side wall through hole corresponding to the strip-shaped through hole 50 is provided on the side wall of the mounting seat 12, and then the bolt is passed through the side wall through hole and the corresponding strip-shaped through hole 50 and locked with a nut, thereby fixing the mounting plate 5 on the mounting seat 12. When the distance from the photoelectric sensor 3 to the axis of the bearing cover 1 needs to be adjusted, the nut is loosened, the mounting plate 5 is pulled a certain distance away from the mounting seat 12, and then the nut is tightened.
