Correspondingly, when the support part 521 rotates inward, the net mouth of the net sleeve output downward becomes smaller, and the fruits and vegetables with small outer diameters can be netted. When the first sensor 9 is detected, When the visual system is used, the outer diameter of the fruit and vegetable can be measured, and the second driving mechanism 6 in the workstation rotates the supporting part 521 to adapt the mesh opening to the outer diameter of the fruit and vegetable.

The sliding base 731 of one power roller assembly 73 is connected to the upper side of the transmission belt 741, and the sliding base 731 of the other power roller assembly 73 is connected to the lower side of the transmission belt 741. The second motor 743 has torque feedback and automatic braking functions.

[0059] Through the above settings, first, the second motor 743 can control the power roller 732 to approach or move away from the movement body 51 without manual adjustment, which is convenient for putting the movement body 51 on the Internet; second, when the power roller 732 squeezes the movement body 51, the torque of the second motor 743 increases. When the torque increases to a preset value, the second motor 743 can automatically brake to make the clamping force of the power roller 732 on the movement body 51 moderate; third, the second motor 743 can drive the two power roller assemblies 73 to move at the same time.

[0060] Specifically, the support seat 71 can be installed in the mesh-covering equipment by bolts. The support seat 71 is basically rectangular, and a notch is provided in the support seat 71 to facilitate the vertical passage of the mesh. The track mechanism 72 is used to guide the sliding base 731 so that the two sliding bases 731 can only move in a straight line. The power rollers 732 of the two power roller assemblies 73 are parallel to each other, and the sliding direction of the sliding base 731 of the power roller assembly 73 is perpendicular to the axis of the power roller 732. When driving the mesh, the power roller 732 clamps the movement, and the mesh is located between the movement and the power roller. When the power roller rotates, the mesh is driven to move downward along the movement. After the mesh is used up, when adding a mesh, the second motor 743 drives the power roller assembly 73 away from the movement body 51, so that a larger gap is generated between the power roller assembly 73 and the movement body 51, and the mesh is covered on the movement body 51 from top to bottom. The movement body 51 supports the inner wall of the mesh. At this time, the mesh is located between the movement body 51 and the power roller 732. The two power roller assemblies The power roller 732 of 73 is at the same distance from the movement body 51; the upper and lower sides of the transmission belt 741 are parallel to the sliding direction of the sliding base 731. When the second motor 743 drives the second pulley 742, the upper and lower sides of the transmission belt 741 move at equal speeds but in opposite directions. One of the power roller assemblies 73 moves toward the movement body 51 along the upper side of the transmission belt 741, and the other power roller assembly 73 moves toward the movement body 51 along the lower side of the transmission belt 741 at the same speed. Finally, the power rollers 732 of the two power roller assemblies 73 contact the outer wall of the mesh sleeve at the same time and gradually clamp the movement body 51. The clamping force gradually increases, and the torque of the corresponding second motor 743 increases. When the torque of the second motor 743 increases to a preset value, the second motor 743 stops and automatically brakes to lock the clamping force. Among them, the second motor 743 with automatic braking and torque feedback functions can be purchased from the market, and the preset value is set by technicians in this field according to actual needs.

[0062] Through the above arrangement, firstly, it is convenient to surf the net; secondly, the active roller 152 and the driven roller 154 can stably clamp the net sleeve to prevent the net sleeve from loosening; thirdly, the encoder 153 is used for counting, and the counting accuracy is high.

[0063] Specifically, the second base 151 can be installed on the mesh device by bolts; the through hole 1511 is square, the active roller 152 is located on the upper side of the second base 151 and is parallel to one side of the through hole 1511; the horizontal projection of the side of the active roller 152 close to the driven roller 154 is located within the horizontal projection of the through hole 1511, so that the mesh sleeve will not contact the hole wall of the through hole 1511 when it moves vertically downward from between the active roller 152 and the driven roller 154; the driven roller 154 is located in the horizontal projection of the through hole 1511. The axis is consistent in height with the axis of the active roller 152; one end of the spring 1554 is connected to the fixed block 1553, and the other end of the spring 1554 is connected to the slider 1552. The spring 1554 is in a compressed state. The spring 1554 pushes the driven roller 154 through the slider 1552. The driven roller 154 and the active roller 152 clamp the mesh sleeve. When the mesh sleeve moves downward, the active roller 152 and the driven roller 154 rotate accordingly, and the active roller 152 and the driven roller 154 give the mesh sleeve a certain resistance. The force is used to keep the mesh sleeve in a tensioned state. The encoder 153 can calculate the number of revolutions of the active roller 152, and then combined with the circumference of the active roller 152, the length of the mesh sleeve output downward can be calculated; when the length of the mesh sleeve output downward is close to the total length of the mesh sleeve, the counting guide mechanism 15 issues an alarm to remind the operator to add a mesh sleeve. When adding a mesh sleeve, the operator manually pushes the driven roller 154, the driven roller 154 moves away from the active roller 152, the slider 1552 approaches the fixed block 1553, and the spring 1554 is compressed. At this time, the driven roller 154 and the active roller 152 are separated, so that the new mesh sleeve is conveniently passed downward between the active roller 152 and the driven roller 154 and sleeved on the movement body 51. After releasing the hand, the spring 1554 automatically recovers, and the spring 1554 pushes the driven roller 154 to move toward the active roller 152 through the slider 1552. The driven roller 154 and the active roller 152 clamp the mesh sleeve again. The process of surfing the Internet does not require the counting guide mechanism 15 to be disassembled and assembled, and surfing the Internet is convenient.
