The bag threading device comprises a machine platform and a net support component, a fixed clamp component, a turning material platform, a movable clamp component, a material pressing clamp component, a cutting component and a net bag traction component arranged on the machine platform. The net support component is arranged at the head end of the machine platform, the net support component can be opened and closed and can be moved along the left and right directions of the machine platform. The fixed clamp component is fixedly connected to the machine platform. When the net support component moves to the working position, the fixed clamp component is located at the front and rear sides of the net support component. The fixed clamp component is used to clamp and release the net support component. The turning material platform is arranged on the machine platform on the side of the net support component away from the head end of the machine platform. The turning material platform is rotatably connected to the machine platform, and the rotation axis is along the left and right directions of the machine platform. The net bag moves on the turning material platform. The mesh bag is movable, a mesh supporting rod for holding open the mesh bag is arranged inside the front end of the mesh bag, a movable clamping assembly which can move left and right along the machine table is arranged on the front and rear sides of the turning material table, the movable clamping assembly is used to clamp and loosen the mesh bag sleeved on the outside of the mesh supporting rod, a pressing clamping assembly which can move downward to press the mesh bag and materials is arranged above the turning material table near the head end of the machine, a cutting assembly which can move left and right and up and down along the machine table is arranged on the side of the pressing clamping assembly away from the head end of the machine, the cutting assembly is used to cut the mesh bag, and the mesh bag traction assembly is arranged at the tail end of the machine table, for conveying the mesh bag to the turning material table. The working process of the automatic bag threading machine is as follows: in the initial position, the mesh supporting assembly is located in the working position, the mesh supporting rod is located on the inner side of the head end of the mesh bag, and the mesh supporting assembly is arranged on the inner side of the head end of the mesh bag. The end portion rests on the head end surface of the net-supporting rod, and the movable clamping assembly moves to both sides of the net-supporting rod to clamp the net bag on the outside of the net-supporting rod, and the movable clamping assembly clamping the net bag and the net-supporting rod moves in the direction of the net-supporting assembly. Since the net-supporting rod is supported by the net-supporting assembly, it cannot move, and the net bag slides on the outside of the net-supporting rod under the drive of the movable clamping assembly.

The upper surface of the above-mentioned material table main body 21 can be evenly provided with grooves arranged along the front and rear directions of the material table main body 21 along the length direction of the material table main body 21. The mesh bag is located on the upper surface of the material table main body 21. When the electric wire cuts, the electric wire can be aligned with the groove for cutting, and the electric wire can move downward into the groove to completely cut the mesh bag.

[0041] The above-mentioned mesh bag traction assembly 12 includes a driving roller, a bag pressing wheel 33 located above the driving roller and a driving motor 35 drivingly connected to the driving roller. A gap for the mesh bag to pass through is left between the driving roller and the bag pressing wheel 33. When the driving roller rotates, the bag pressing wheel 33 increases the friction between the mesh bag and the driving roller and drives the mesh bag to move forward. A plurality of bag supporting wheels 34 can also be arranged on both sides of the driving roller. The rotation axes of the driving roller, the bag pressing wheel 33 and the bag supporting wheels 34 can all be along the front and rear directions of the machine table 4, and the plurality of bag supporting wheels 34 can be on the same horizontal plane as the axis of the driving roller.

[0042] The above-mentioned feeding device 2 can be a chain plate feeder. The chain plate feeder includes a chain plate and rollers arranged in the front-rear direction of the machine table 4, one being a driving roller and the other being a driven roller. The driving roller can be controlled to rotate by a servo motor. Both rollers extend in the left-right direction of the machine table 4. Sprockets cooperating with the chain plate are arranged on each roller. A discharging groove 36 extending in the left-right direction of the machine table 4 is arranged on each chain plate. The discharging groove 36 can be arc-shaped or trapezoidal in structure. When multiple net supporting pieces 16 are opened radially, the bottom end of the top surface of the discharging groove 36 in the working position can be flush with the bottom end of the inner side surface of the lowermost net supporting piece 16. Such a setting can align the channel formed by the material placed on the discharging groove 36 and the multiple net supporting pieces 16, and the material can be directly pushed into the channel. An introducing plate extending downward at the head end of the machine table 4 can be arranged at the head ends of the two net supporting pieces 16 in the up-down direction. The bottom end of the introducing plate can extend below the bottom end of the discharging groove 36 to make it easier for the material to enter the channel.

[0043] The above-mentioned material pushing device can include a push rod 37 and a third driving device 38 for driving the movement of the push rod 37. The axis of the push rod 37 is collinear with the axis of the through hole. In this way, the axes of the push rod 37, the material, and the through hole are collinear, and the push rod 37 pushes the material into the through hole in a straight-line motion. The third driving device 38 can include a mounting housing 39. The push rod 37 passes through the mounting housing 39 in the left-right direction of the machine table 4. Rollers 40 are arranged on the upper and lower sides of the positions where the left and right ends of the mounting housing 39 are in contact with the push rod 37 to make the sliding of the push rod 37 smoother. A driving wheel 41 with an axis in the vertical direction is arranged on the front side or the rear side of the push rod 37. The driving wheel is rotatably connected to the mounting housing 39. A motor 42 can be installed at the bottom of the driving wheel 41. When the driving wheel 41 rotates, it drives the push rod 37 to move by means of friction.

[0044] The automatic bagging machine further includes a PLC controller for controlling and coordinating the movements of the above-mentioned various mechanisms. The above-mentioned motor 42, the servo motor for controlling the rotation of the driving roller, the first cylinder 17, the second cylinder 18, the third cylinder 20, the fourth cylinder 22, the first driving device 24, the fifth cylinder 25, the sixth cylinder 27, the second driving device 30, the seventh cylinder 31, and the driving motor 35 are all communicatively connected to the PLC controller, and the PLC controller controls the movement processes of the various mechanisms uniformly.
