A base frame 402 is fixedly provided at the bottom of the feeding table 401. Two fixed plates 403 arranged at a front-to-back interval are fixedly provided on the top of the feeding table 401. Two clamps 404 arranged at a front-to-back interval and capable of being adjusted front and back are provided between the two fixed plates 403. The bottom of the clamp 404 slides against the feeding table 401. The two clamps 404 are used to store vertically stacked black wolfberry self-supporting bags. A guide plate 405 is fixedly provided at the right end of the clamp 404. The guide plate 405 can guide the black wolfberry self-supporting bags transported to the right.

[0036] A conveying mechanism is provided on the feeding mechanism 4, and the conveying mechanism is used to convey the black wolfberry self-supporting bag to the conveyor 1. Specifically, the conveying mechanism includes two second rotating shafts 501 rotatably arranged in the feeding platform 401, and a roller 502 is fixed on the second rotating shaft 501. The top end of the roller 502 passes through the feeding platform 401, and the roller 502 can convey the black wolfberry self-supporting bag when rotating.

[0037] The feeding mechanism 4 is provided with a second driving mechanism, which is transmission-connected with the two second rotating shafts 501, and the second driving mechanism is used to drive the second rotating shafts 501 to rotate. Specifically, the front end of the second rotating shaft 501 on the left passes through the feeding platform 401 and is fixedly provided with a first single-wheel universal wheel 503, and the front end of the second rotating shaft 501 on the right passes through the feeding platform 401 and is fixedly provided with a double-wheel universal wheel 504, the first single-wheel universal wheel 503 is transmission-connected with the double-wheel universal wheel 504 through a belt, and the driving roller 104 on the left passes through the frame 102 and is fixedly provided with a first single-wheel universal wheel 503. There is a second single-wheel universal wheel 505, which is connected to the double-wheel universal wheel 504 through a belt; the first single-wheel universal wheel 503 and the double-wheel universal wheel 504 have the same wheel diameter, the second single-wheel universal wheel 505 has a smaller wheel diameter than the double-wheel universal wheel 504, and the outer diameter of the roller 502 is the same as the outer diameter of the end of the conveyor belt 105, so that the conveying speed of the roller 502 for the black wolfberry self-supporting bag is lower than the conveying speed of the conveyor belt 105, so that the black wolfberry self-supporting bag can be conveyed at intervals, avoiding problems in subsequent flattening and labeling due to the black wolfberry self-supporting bags being too close.

[0038] When the driving motor 106 drives the driving shaft 103, the driving roller 104 and the conveyor belt 105 for transmission, the driving shaft 103 on the left drives the two second rotating shafts 501 and the roller 502 to rotate through the first single-wheel universal wheel 503, the double-wheel universal wheel 504, the second single-wheel universal wheel 505 and the belt, so that the conveyor 1 drives the roller 502 to rotate at the same time during the transmission process, so as to transport the black wolfberry self-supporting bags on the feeding table 401, thereby reducing costs.

[0039] A rod 409 extending forward is fixedly provided on the fixed plate 403 located at the rear, and an arc plate 410 is fixedly provided at the front end of the rod 409. The arc plate 410 is located between the two guide plates 405. The arc plate 410 is arranged to be inclined in an arc shape from top to bottom and from left to right. A gap is left between the right end bottom of the arc plate 410 and the feeding table 401 for a black wolfberry self-supporting bag to pass through, so that the black wolfberry self-supporting bags vertically stacked between the clamping plates 404 can be affected by the arc slope of the arc plate 410 during the rightward conveying process, thereby generating downward pressure on the stacked black wolfberry self-supporting bags, so that the black wolfberry self-supporting bag at the bottom can be firmly attached to the roller 502.

[0040] Two guide rods 406 are fixedly arranged between the two fixed plates 403, and the guide rods 406 are slidably penetrated on the top of the guide plate 405, and the guide rods 406 are used to guide the guide plate 405 to move horizontally forward and backward; an adjustment mechanism is provided on the clamping plate 404 for adjusting the clamping plate 404 forward and backward, specifically, the adjustment mechanism includes a bidirectional screw 407 rotatably arranged between the two fixed plates 403, the bidirectional screw 407 includes a front threaded rod and a rear threaded rod, and the front threaded rod and the rear threaded rod have opposite thread directions, and the right ends of the two guide plates 405 are provided with front and rear transparent internal threaded holes, and the thread squares of the two internal threaded holes are opposite, and the two guide plates 405 are respectively threadedly sleeved on the front threaded rod and the rear threaded rod of the bidirectional screw 407 through the two internal threaded holes, and the rear end of the bidirectional screw 407 passes through the fixed plate 403 and is fixed with a handle 408.

[0041] By manually turning the handle 408 to drive the bidirectional screw 407 to rotate, the two guide plates 405 and the two clamping plates 404 are driven to move relative to or towards each other along the guide rod 406, thereby changing the distance between the two guide plates 405 and the two clamping plates 404, so that the feeding mechanism 4 can feed black wolfberry self-supporting bags of different widths.

[0042] Working principle: When in use, the size of the black wolfberry self-supporting bag is determined by rotating the handle 408 to drive the bidirectional screw 407 to rotate, thereby driving the two guide plates 405 and the two clamping plates 404 to move relative to or toward each other along the guide rod 406, changing the distance between the two guide plates 405 and the two clamping plates 404, making the distance between the two clamping plates 404 the same as the width of the black wolfberry self-supporting bag, and then placing the vertically stacked black wolfberry self-supporting bags between the two clamping plates 404.

[0043] When labeling the black wolfberry self-supporting bag, the driving motor 106 is started to drive the driving shaft 103 to rotate, and then the driving roller 104 and the conveyor belt 105 are driven to rotate. At the same time, the driving shaft 103 on the left drives the two second rotating shafts 501 and the roller 502 to rotate through the first single-wheel universal wheel 503, the double-wheel universal wheel 504, the second single-wheel universal wheel 505 and the belt, so that the black wolfberry self-supporting bag at the bottom is moved to the right and transported to the conveyor belt 105; at the same time, the driving shaft 103 on the left drives the second straight gear 205 to rotate. The two spur gears 206 rotate, driving the first rotating shaft 202, the roller 203 and the plurality of ribs 204 to rotate, so that when the right end of the black wolfberry self-supporting bag entering the left end of the conveyor belt 105 is tilted, the right end of the black wolfberry self-supporting bag is inserted between the two ribs 204, and the rotating ribs 204 flatten the end of the black wolfberry self-supporting bag and convey it together with the conveyor belt 105. After the black wolfberry self-supporting bag passes under the roller 203 and the ribs 204, the front and rear sides of the black wolfberry self-supporting bag are pressed under the pressure rod 209 and continue to be conveyed to the right to the labeling device for labeling.
