Then, the staff will express package placed in the left side of the transmission belt 203 in turn, and the express needs to be placed between the two boundary strips 204, and the express package enters the inside of the fixed frame 11 with the movement of the transmission belt 203, and when the infrared sensor 14 detects the express package, the control chip built-in infrared sensor 14 controls the output end of the transmission motor 205 to stop rotating, so that the transmission belt 203 stops moving, and the right side of the express package corresponds to the position of the infrared sensor 14, and since the infrared sensor 14 is located in the right position inside the support frame 10, the express package is approximately located below the labeling machine body 13, thereby achieving the effect of preliminary positioning, and the size, position and height of the express package are accurately detected by the photoelectric sensor.

[0025] Reference Figures 2-4 , the inside of the fixed frame 11 is provided with a positioning mechanism 30, the positioning mechanism 30 includes mounting groove 301 respectively opened in the front and back sides of the inside of the fixed frame 11, and the opposite sides of the two mounting grooves 301 are provided with positioning blocks 309 which can move towards and away from each other.

[0026] Specifically, reference Figure 4The inside left side of the installation slot 301 is fixedly connected with a connecting box 302, the inside left and right sides of the connecting box 302 are jointly rotatably connected with a one-way threaded rod 303, the outside of the one-way threaded rod 303 is threadedly connected with a moving block 304, the rear side of the moving block 304 is hingedly connected with a left cross arm 306 through a hinge, the right side of the connecting box 302 is fixedly installed with a position adjusting motor 305, the position adjusting motor 305 is fixedly connected with the one-way threaded rod 303; the right side of the installation slot 301 is fixedly connected with a positioning frame 307, the inside of the positioning frame 307 is hingedly connected with a right cross arm 308 through a movable shaft, the left cross arm 306 and the right cross arm 308 are cross-disposed and coincide, and the left cross arm 306 and the right cross arm 308 are hingedly connected through a rotating shaft at the coinciding position; the front left side of the positioning block 309 is fixedly connected with a sliding box 311, the inside of the sliding box 311 is hollow and the front side is open, the inside left and right sides of the sliding box 311 are jointly fixedly connected with sliding rods, the outside of the sliding rods is slidingly connected with a connecting block 312, the front side of the connecting block 312 is hingedly connected with the other end of the right cross arm 308 through a hinge, the front right side of the positioning block 309 is fixedly connected with a movable frame 310, and the inside of the movable frame 310 is hingedly connected with the other end of the left cross arm 306 through a rotating shaft.

[0027] After the photoelectric sensor detects the size and position of the express delivery, the control chip built-in the photoelectric sensor starts two positioning motors 305 through external power supply, the output end of the two positioning motors 305 drives the rotation of the one-way threaded rod 303, thereby driving the moving block 304 to move from left to right, thereby making the left end of the left cross arm 306 slowly move to the right and making the left cross arm 306 reverse counterclockwise. Since the left cross arm 306 is hinged with the right cross arm 308, the right cross arm 308 will be reversed in the opposite direction, and the right cross arm 308 will rotate clockwise around the pivot inside the positioning frame 307, making the left end of the right cross arm 308 drive the connecting block 312 to slide along the surface of the sliding rod from left to right, thereby gradually reducing the angle between the left cross arm 306 and the right cross arm 308, making the overall length of the X-shaped bracket formed by the left cross arm 306 and the right cross arm 308 longer, and driving the two positioning blocks 309 to move towards each other. And according to the size of the express delivery package feedback by the photoelectric sensor, the speed and rotation time of the output end of the positioning motor 305 are controlled correspondingly, thereby controlling the distance of the two positioning blocks 309 moving towards each other, so that the two positioning blocks 309 drive the express delivery package to the middle position inside the fixed frame 11 without damaging the outer packaging of the express delivery package. Similarly, when the express delivery is labeled, the control chip built-in the photoelectric sensor reverses the output end of the positioning motor 305, thereby driving the moving block 304 to move from right to left, making the left end of the left cross arm 306 move in the same direction, and making the left cross arm 306 rotate clockwise, thereby driving the right cross arm 308 to rotate counterclockwise around the pivot inside the positioning frame 307, and making the left end of the right cross arm 308 move from right to left while driving the connecting block 312 to move along the surface of the sliding rod from right to left, thereby making the overall length of the X-shaped bracket formed by the left cross arm 306 and the right cross arm 308 shorter, and driving the two positioning blocks 309 to move away from the surface of the express delivery package, until the two positioning blocks 309 return to the initial position. The positioning mechanism 30 adopts cross expansion instead of directly using a cylinder because even in the state that the output end of the cylinder does not extend, it will occupy a large longitudinal space, so after installing the positioning block 309 and other components on the cylinder, it will affect the transmission of the large express box body through the transmission belt 203, so more space is needed in the design, which makes the overall device need more floor space.

[0028] Further, with reference to Figure 4 , the rear side of the positioning block 309 is fixedly connected with a group of mounting seats 313, and the inside of the mounting seat 313 is installed with a roller 314; in use, the two positioning blocks 309 move towards each other, and the rollers 314 on both sides contact the express delivery package, moving the front and rear sides of the express delivery package to the middle position.

[0030] After positioning the front and back sides of the express package, the control chip built-in the photoelectric sensor starts the positioning motor 319 through the external power supply, the output end of the positioning motor 319 drives the bidirectional threaded rod 315 to rotate, thereby driving the two L-shaped blocks 316 and the push blocks 317 to move towards each other, the push blocks 317 drive the express package to move to the central position, the positioning motor 319 is controlled according to the size of the express package feedback by the photoelectric sensor, thereby controlling the moving distance of the two push blocks 317, the two push blocks 317 move the express to the middle position without damaging the surface of the express package, meanwhile, the express slides along the surface of the roller 314 without separating from the center, thereby reducing the friction of the positioning block 309, so as to achieve accurate positioning of the express package, then the body 13 of the labeling machine is lowered to the appropriate position through the extension of the output end of the air cylinder 12, the central position of the express package is labeled by the body 13 of the labeling machine, then the positioning mechanism 30 returns to the initial position, the express after labeling is removed through the opening of the conveying mechanism 20, the next express package is moved to the inside of the fixed frame 11, and the above operation is repeated to achieve the effect of labeling the express.

[0031] The working principle of the utility model is: after the photoelectric sensor detects the size and position of the express, the control chip built-in the photoelectric sensor starts two position adjusting motors 305 through the external power supply, the output end of the two position adjusting motors 305 drives the rotation of the unidirectional threaded rod 303, thereby driving the moving block 304 to move from left to right, thereby making the left end of the left cross arm 306 slowly move right, and making the left cross arm 306 counterclockwise turn over, because the left cross arm 306 is hinged with the right cross arm 308, so the right cross arm 308 will turn over in the opposite direction, and the right cross arm 308 clockwise turns over with the pivot in the inside of the positioning frame 307 as the center, making the left end of the right cross arm 308 drive the connecting block 312 to slide along the surface of the sliding rod from left to right, thereby making the included angle between the left cross arm 306 and the right cross arm 308 gradually reduce, making the whole X-shaped support formed by the left cross arm 306 and the right cross arm 308 lengthen, driving the two positioning blocks 309 to move towards each other, the control chip built-in the photoelectric sensor starts the positioning motor 319 through the external power supply, the output end of the positioning motor 319 drives the rotation of the bidirectional threaded rod 315, thereby driving the two L-shaped blocks 316 and the push blocks 317 to move towards each other, the push blocks 317 drive the express package to move to the central position, thereby achieving the effect of accurate positioning.
