Example 1

As shown in fig. 1 and fig. 2, the mesh bag set conveying system of the present embodiment includes a core barrel 1, a driving roller assembly and a driven roller assembly, and the mesh bag to be conveyed is set on the core barrel 1. The main power roller assembly comprises a first main power roller 21 and a second main power roller 22, wherein the first main power roller 21 and the second main power roller 22 are respectively arranged on two sides of the core barrel 1, limit is carried out on the core barrel 1 in the vertical direction and the circumferential direction, and meanwhile, the mesh bag is driven to move upwards. The driven roller assembly is positioned below the driving roller assembly and comprises a first driven roller 31 and a second driven roller 32, and the first driven roller 31 and the second driven roller 32 are respectively arranged at two sides of the core barrel 1 and limit the core barrel 1 in the horizontal direction. The core barrel 1 in a suspended state can be fixed by the mutual matching of the main power roller assembly and the driven power roller assembly. In traditional design, adopt two sets of drive arrangement to drive, when two sets of drive arrangement are asynchronous, the pocket receives easily to tear and damaged. In the design, only one group of power rollers is needed for driving, and the risk of tearing the mesh bag caused by asynchronous driving can be effectively avoided.

Specifically, the first driving roller 21 and the second driving roller 22 have the same structure and are both cylindrical. The core barrel is characterized in that limiting grooves 4 are formed in the core barrel 1 symmetrically, a first main power roller 21 and a second main power roller 22 are arranged in the corresponding limiting grooves 4 and are arranged in parallel, and the first main power roller 21 and the second main power roller 22 limit the core barrel 1 from two sides. Meanwhile, since the limiting groove 4 is a groove as a whole, the movement of the cartridge 1 in the vertical direction and the rotation in the axial direction thereof are also limited. In short, the core barrel 1 can move in a wide range only in the axial direction of the first main power roller 21 by the cooperation of the first main power roller 21, the second main power roller 22, and the stopper groove 4.

As shown in fig. 2, 4 and 7, the limiting groove 4 is an arc-shaped groove as a whole, and the cross section of the limiting groove is an arc 41, and the arc 41 has a radian matched with the arc part of the driving roller limited in the limiting groove 4. By the design, the main power roller is more uniformly attached to the limiting groove 4, so that each part of the mesh bag is relatively balanced by the friction force from the main power roller, and the stable rising of the mesh bag is ensured. In order to stably limit the core barrel 1 in the vertical direction, the limiting groove 4 needs to have a certain depth, the depth of the limiting groove 4 cannot be too small, and if the depth is too small, the limiting effect of the core barrel 1 in the vertical direction cannot be achieved, so that the core barrel 1 is easy to fall off; the mesh bag can not be too large, if the depth is too large, the deformation of the mesh bag at the position of the limiting groove 4 is too large, and the mesh bag is easy to block. Preferably, the opening depth H of the limiting groove 4 is 1/3 to 5/12 of the diameter of the core barrel 1.

As shown in fig. 5 and 6, the driven roller assembly of the present embodiment includes a first driven roller 31 and a second driven roller 32, the first driven roller 31 and the second driven roller 32 have the same structure and are symmetrically disposed on both sides of the core barrel 1, the first driven roller 31 has a dumbbell shape as a whole, and includes a first end portion 311, a second end portion 312, and an intermediate portion 313 connecting both end portions, and the intermediate portion 313 is a concave curved surface. Thus, the first driven roller 31 and the second driven roller 32 wrap the core barrel 1 from both sides, and the core barrel 1 is restricted from moving forward, backward, leftward and rightward in the horizontal plane. In addition, the core barrel 1 is limited by the driving force roller assembly in the vertical degree of freedom and the rotational degree of freedom, so that the core barrel 1 can be ensured to be in a stable state in the working process. Preferably, the first driven roller 21 is arranged perpendicularly to the first driven roller 31.

To further ensure smooth movement of the mesh bag, the concave curved surface of the intermediate portion 313 is fitted to the outer peripheral wall of the core barrel 1 wrapped by the first driven roller 31, and is concentric therewith. Preferably, the arc of the first driven roller 31 wrapping the outer peripheral wall portion of the core barrel 1 is 90 ° to 150 °. If the wrapped part of the core barrel 1 is too small, the limiting effect of the driven roller assembly on the core barrel 1 is poor, and the position of the core barrel 1 is easy to deviate after being stressed in the working process; if the wrapped part of the core barrel 1 is too large, even the outer peripheral wall of the whole core barrel 1 is completely wrapped, so that the frictional resistance of the mesh bag from a power roller is increased, and the mesh bag is not beneficial to rising; in addition, the size of the power roller assembly also needs to be increased, thereby occupying a large space.

In order to ensure the moving efficiency of the mesh bag, the surfaces of the core barrel 1, the first driven roller 31 and the second driven roller 32 need to be subjected to surface treatment so as to reduce the friction coefficient with the plastic foaming mesh bag and reduce the friction resistance. The first driving roller 21 and the second driving roller 22 need to be made of materials with high friction coefficients to improve the friction driving force between the plastic foaming mesh bag and the driving roller. In this embodiment, the first driving roller 21 and the second driving roller 22 are both rubber-coated driving rollers, and the rubber-coated portion is made of rubber with a large friction resistance coefficient, and transmits an upward traction force through friction, so as to achieve the purpose of bagging the foamed mesh bag. In order to further reduce the frictional resistance of the mesh bag, unpowered roller beads 5 are arranged in the limiting groove 4 and/or on the surface of the core barrel 1. Specifically, in this embodiment, 1 set of unpowered roller beads 5 is disposed in the limiting groove 4 and distributed along the vertical direction. The unpowered roller beads 5 of the part, wrapped by the first driven power roller 31 and the second driven power roller 32, on the core barrel 1 are kidney-shaped roller beads, the kidney-shaped roller beads are provided with 6 groups along the circumferential direction of the core barrel 1, and each group of kidney-shaped roller beads are also distributed along the vertical direction. The protruding cambered surface of waist shape roller pearl can carry out better laminating with the indent curved surface of first follow power roller 31 to guarantee that the atress of pocket is even. The foaming mesh bag penetrates through a gap between the dumbbell-shaped secondary power roller and the waist-shaped roller bead to form a line contact mode, so that the frictional resistance is reduced. The two ends of the dumbbell-shaped unpowered roller are arranged on the bearings, a driving device does not need to be added, and the dumbbell-shaped unpowered roller is simple in structure.

In order to conveniently install the unpowered roller balls 5, the unpowered roller balls 5 are designed in a special structure. Specifically, referring to fig. 4, the unpowered roller 5 is provided with a stepped hole therein, and both ends of the unpowered roller are respectively provided with a non-telescopic middle rotating shaft 51 and a telescopic middle rotating shaft 52. The non-telescopic middle rotating shaft 51 is made of stainless steel, one end (far away from the non-telescopic middle rotating shaft 51) of the telescopic middle rotating shaft 52 is a stainless steel shaft, a compression spring is arranged at the other end, and the telescopic middle rotating shaft 52 can be contracted into the step hole by pressing the end of the stainless steel shaft. The notch for installing the unpowered roller bead 5 is correspondingly provided with shaft holes for installing two ends of the unpowered roller bead 5.

In order to further facilitate the opening of the shaft hole, the core barrel 1 in this embodiment is integrally formed, and a 3D printing technology may be adopted. When the installation is carried out, the non-telescopic middle rotating shaft 51 is firstly installed in the corresponding shaft hole, then the telescopic middle rotating shaft 52 is pressed, the spring is contracted, the stainless steel shaft end is aligned to the opposite shaft hole, and the hand is loosened immediately. Under the action of the restoring force of the spring, the end part of the telescopic middle rotating shaft 52 is clamped into the shaft hole, and the installation operation is completed.

In addition, in order to facilitate the disassembly, a disassembly hole is correspondingly arranged at the shaft hole of the telescopic middle rotating shaft 52. When the roller ball 5 is disassembled, the top is used for applying certain pressure to the stainless steel shaft end of the telescopic middle rotating shaft 52 to force the spring to extrude, so that the stainless steel shaft end is separated from the shaft hole, the disassembly of the unpowered roller ball 5 is completed, and the operation is convenient and rapid.

In the embodiment, the lower end of the core barrel 1 is provided with a guide section 11, and the upper end is provided with an expansion section 12, wherein the guide section 11 is in a conical structure, a truncated cone structure or a wedge-shaped structure; the expanding section 12 is in a cone frustum-shaped structure, and a containing part 6 is arranged in the expanding section 12, and the containing part 6 is used for containing fruits to be packaged.

When the device works, the mesh bag is sleeved on the core barrel 1, and the first main power roller 21 and the second main power roller 22 extrude the mesh bag and drive the mesh bag to move upwards. Under the common limiting action of the main power roller assembly and the driven power roller assembly, the core barrel 1 can be always in a stable state. In addition, due to the arrangement of the unpowered roller beads 5, the frictional resistance on the mesh bag is reduced, and the mesh bag can move upwards. In the ascending process of the mesh bag, the core barrel 1 is continuously subjected to upward friction traction force, and in order to further ensure the stability of the transmission process, the core barrel 1 can be provided with a certain self-weight block according to the requirement so as to overcome the upward friction traction force.

The dumbbell-shaped driven roller wraps the outer surface of the core barrel 1, and the stability of the core barrel is obviously improved. In addition, the dumbbell-shaped driven power roller is in line contact with the foaming mesh bag, the frictional resistance is suddenly reduced, and meanwhile, the mesh bag is extruded and deformed only once in the conveying process, so that the foaming mesh bag is slightly damaged.
