DETAILED DESCRIPTION

[0032] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0033] See also Figures 1 to 14The embodiment of the present invention discloses an automatic net bag baling machine, which mainly includes a frame 1, and a blanking device, a clamping device, a pushing device, a binding device and auxiliary equipment arranged on the frame 1. The frame 1 is a rectangular structure to reduce the occupied space. The material dropping device is located at the top of the frame 1, and includes a receiving hopper 101 and multiple receiving tubes 102. The receiving hopper 101 is used to receive materials to be packaged, such as fruits, vegetables, etc. The receiving tubes 102 are evenly distributed below the receiving hopper 101 to ensure that the materials can fall into the net bag smoothly. A turntable 104 is arranged on the top of the receiving tube 102. The turntable 104 is provided with multiple receiving holes connected to the receiving tube 102. The turntable 104 is driven by a driving device (such as a motor and a reducer) to realize the rotation of the receiving tube 102. During use, a longer net bag is completely sleeved on the receiving tube 102. During the packaging process, the net bag is cut by the cutter 8 in the sealing device. The multiple receiving tubes 102 enable the net bag to be manually sleeved on the receiving tube 102 by another receiving tube 102 when one receiving tube 102 is working, so that continuous packaging production can be achieved. The rotating shaft 105 is arranged in the middle position of the rotating disk 104 to support the rotating disk 104 and improve stability. The rotating disk 104 is connected to the motor through a belt. The motor is used to rotate the connecting tube 102 during driving to ensure stable use. The clamping device is located below the connecting tube 102, and includes a rotating drum 103 rotatably connected to the rotating shaft 105 and an elastic clamping rod 1031. The rotating drum 103 rotates synchronously with the rotating disk 104. The middle position of the rotating drum 103 is rotatably arranged on the rotating shaft 105, so that the longer connecting tube 102 remains stable. The elastic clamping rod 1031 abuts against the side wall of the connecting tube 102 through its elastic force, thereby stably fixing the net bag sleeved on the connecting tube 102, and pulling the net bag downward according to the push of the pushing device, maintaining a stable supply of net bags, improving the stability of use during packaging, ensuring the packaging effect, and improving production efficiency.

[0034] The pushing device is arranged below the material receiving pipe 102, and the pushing device includes a pushing rod and a pushing plate 2 horizontally arranged on the frame 1, a sliding bar 201 is arranged below the pushing plate 2, and the pushing plate 2 is connected to the sliding bar 201 through a slider, so that the pushing plate 2 can slide stably and directionally on the sliding bar 201, and the pushing rod is driven by a motor, and a rocking arm 202 is arranged at the output end of the motor, and a connecting rod 203 is hinged at the end of the rocking arm 202, and the connecting rod 203 is hinged to the pushing plate 2, and the pushing plate 2 is relatively arranged with two pieces, which are supported by a bracket in the middle. When the motor rotates, the sliding of the pushing plate 2 is realized by the swing of the connecting rod 203 and the connecting rod 203. When in use, the connecting rod 203 contracts, and a gap for accommodating a net bag is left between the pushing plate 2 and the limit plate 6, and the bottom of the net bag will be moved before it is sleeved. The net bag is sealed to prevent material from falling during the first packaging. Due to the action of the clamping rod 1031, the net bag will not continue to fall. After the net bag is loaded with materials, the pushing plate 2 is started to push the net bag loaded with materials toward the limit plate 6. The bottom of the net bag has a certain weight after loading, which is convenient for the pushing plate 2 to push. The two pushing plates 2 can ensure the stability of the net bag during the pushing process. During the pushing process, the net bag is pulled downward to provide space for the next material. The entire processing process is stable and continuous to ensure the production effect. The height of the pushing plate 2 can be adjusted by the bracket between the pushing plates 2, which is convenient for adapting to different production between different materials. The adjustment is simple and the production is convenient. After the pushing plate 2 is retracted, there is space between it and the bottom of the material receiving pipe 102 to ensure that the material can fall into the net bag evenly and accurately.

[0035] The binding device is located below the pushing device, and includes a receiving frame, a conveying device, a guiding device and a sealing device. The receiving frame includes two relatively arranged limit plates 6. The limit plates 6 are arranged on the upper and lower surfaces of the guide block 7. A V-shaped notch is arranged in the middle position of the limit plate 6. When the pushing plate 2 pushes the net bag over, the scattered net bag is gathered inside the V-shaped notch through the V-shaped notch and guided into the binding process.

[0036] The conveying device includes a material tray 5, a guide tube 501 and a conveying box 502 arranged on the side of the frame 1 for placing the binding wire. The binding wire is an aluminum strip, which is sleeved on the material tray 5. The guide tube 501 is bent, and the binding wire extends from the material tray 5 and passes through the guide tube 501 to eliminate the bending stress. After passing through the guide tube 501, the binding wire enters the hole on the side of the conveying box 502 and enters the driven wheel 503 inside the conveying box 502 and the driving wheel 504 connected to the motor. The driven wheel 503 is provided with a accommodating groove for accommodating the conveyed binding wire. The binding wire is conveyed forward by squeezing and rotating the driving wheel 504 and the driven wheel 503. A plurality of tooth blades are provided on the side of the driving wheel 504 for processing indentations on the binding wire. Processing the indentation on one side facilitates bending in the guide groove 702 along the direction of the guide groove 702 to improve the binding effect. The setting of the tooth blade increases the power when the binding wire is conveyed to prevent slipping during the conveying process. The conveying length can be set according to the needs of use, the control is accurate, and the structure is reliable. The tooth blade is provided with an upper tooth 5041 and a lower tooth 5042, the top of the upper tooth 5041 is higher than the lower tooth 5042 by 0.5-1mm, and the hinge of the upper tooth 5041 and the lower tooth 5042 is arranged at the upper part of the receiving groove, so that when the binding wire is conveyed and moved, the upper tooth 5041 acts on the upper part of the side of the binding wire, and the depth is slightly deeper, so that when the binding wire moves downward along the guide groove 702, the upper side of the binding wire can also be stretched according to the moving distance, offsetting a part of the material stress and improving the processing effect. A grinding wheel 505 for grinding the tooth blade is arranged on the side of the driving wheel 504, and the grinding teeth on the side of the grinding wheel 505 are meshed with the tooth blade. After a certain period of use, the motor connected to the grinding wheel 505 is started, and the grinding wheel 505 is driven to slide up and down along the tooth blade through the rocker arm 5051 and the eccentric wheel 5052, and the tooth blade is polished by the up and down sliding of the grinding wheel 505, thereby extending the maintenance time and extending the service life.

[0037] The guide device includes a guide plate and a guide block 7. A hole for passing the binding wire is provided on the guide plate. After the binding wire passes through the driving wheel 504, it passes through the guide plate and enters the inside of the guide block 7. A receiving hole 701 is provided in the middle position of the guide block 7. A spiral downward guide groove 702 is provided on the inner wall. The inlet of the guide groove 702 is opposite to the outlet of the conveying box 502. The design of the guide groove 702 ensures that the binding wire can be smoothly wound along the edge of the net bag. An opening is provided on the side of the receiving hole 701. After the push plate 2 pushes the net bag to the bottom of the V-shaped notch on the limiting plate 6, the squeezed net bag enters the inside of the receiving hole 701 through the V-shaped notch, forming an effect of squeezing the bundle. The binding wire moves along the guide groove 702 so that the binding wire rotates around the net bag at least twice. The starting position of the guide groove 702 is set to be closed by a sealing plate 7021, and an opening is set on the side of the guide groove 702 after the binding wire passes through the opening, and the opening angle is 120-160 degrees. The diameter depth of the guide groove 702 at the opening part is greater than the diameter of the binding wire, and the side wall of the opening where the binding wire passes through the accommodating port is set to a trumpet shape, so that the binding wire can quickly enter the guide groove 702 when passing through the opening and move along the guide groove 702. The opening angle of the guide groove 702 is 120-160 degrees. The binding wire has a certain resistance when it moves inside to escape, so as to prevent it from being hooked with the net bag. The binding wire can escape from the guide groove 702 only when it is subjected to force, thereby ensuring the winding effect of the binding wire screen. When in use, the binding wire is transported by the driving wheel 504 and enters the interior of the guide block 7 along the guide groove 702. After the net bag enters the accommodating hole 701, the binding wire is transported and moves along the guide groove 702. After winding around the net bag for at least two weeks, the binding wire is squeezed and cut to form a sealing effect on the net bag. The part of the binding wire at the upper part of the guide groove 702 after cutting will remain inside, and part of it will block the opening of the accommodating hole 701. At this time, the driving wheel 504 rotates in the opposite direction, and this part of the binding wire enters the interior of the guide groove 702 with the sealing plate 7021. The setting of the sealing plate 7021 ensures the moving direction of the binding wire. After the net bag enters the accommodating hole 701, the driving wheel 504 rotates forward, and then the net bag continues to be wound, realizing repeated production, ensuring the control effect of the binding wire, and improving the sealing effect.

[0038] The sealing device includes a sliding rod 601, a telescopic motor 602, a cutter 8 and a driving cylinder 801. The sliding rod 601 is driven by the telescopic motor 602. A limit block 603 is arranged on the outer side of the sliding rod 601 to limit the movement of the sliding rod 601. A pressing block 9 is arranged on the output end of the sliding rod 601. A guide groove 702 on the side of the pressing block 9 is arranged on the pressing block 9. When the pressing block 9 is reset, the guide groove 702 is connected as a whole. After the binding wire passes through, the telescopic motor 602 is actuated. The sliding rod 601 moves to the right, and the pressing block 9 on the left drives the binding wire on the left to be squeezed to the right. Two pressing blocks 9 are provided, which are convenient for forming two sealing places on the net bag. A cutting knife 901 for cutting the net bag is also provided between the two pressing blocks 9. When the pressing block 9 is extended, the cutting knife 901 is extended at the same time, and the net bag is cut after the binding wire is pressed and sealed, so that no seal is formed on the net bag loaded with materials at the bottom, and the upper net bag is used as the bottom of the next net bag for sealing, which is convenient for the next production, forms continuous production, and improves processing efficiency. The cutter 8 is arranged on the other side of the accommodating hole 701, and two cutters 8 are arranged. The upper cutter 8 is used to cut the connection between the binding wire on the material tray 5 and the upper net bag, and the lower cutter 8 is convenient for cutting the binding wire between the two net bags. The knife hole of the cutter 8 is arranged on the path of the guide groove 702. When the cutter 8 is cutting, the two cutters 8 are driven to move to the right side at the same time by the driving cylinder 801, so as to achieve the effect of cutting the binding wire. The clamping block 9 and the cutter 8 can move at the same time so that the cutter 8 does not affect the movement of the clamping block 9. After the clamping block 9 is reset, the cutter 8 is reset to complete a sealing operation. A material receiving trough 3 is arranged below the limit plate 6, and a lifting screw rod 301 is arranged at the lower part of the material receiving trough 3. After the net bag after packaging is sealed, it falls into the inside of the material receiving trough 3. The height of the material receiving trough 3 is adjusted by the lifting screw rod 301 to reduce the falling and injury of the material and ensure the processing effect.

[0039] In order to improve the traceability and aesthetics of the product, a labeling device is arranged above the guide block 7, and the output end of the labeling device is arranged above the accommodating hole 701. When in use, the labeling machine 4 transports the bottom edge of the label to the inside of the accommodating space, and the binding wire also presses the bottom of the label inside after being squeezed and compressed by the pressing block 9. Even if part of the label is stuck on the binding wire at the bottom during cutting by the cutting knife 901, it will not be affected. The information of the label is on the upper part, and the two labels are provided with shear marks. When the upper net bag falls toward the material receiving pipe 102, the knife at the bottom of the labeling machine 4 will cut the label along the shear mark. After completion, the labeling machine 4 will act to transport the bottom of the next label to the inside of the accommodating hole 701 for the next production. The net bag can be labeled when the sealing is completed, completing the sealing and labeling of the whole set of net bags, realizing a fully automated process from blanking, clamping, pushing, binding to labeling, greatly improving the packaging efficiency and production continuity, reducing labor costs, and reducing the waste of packaging materials.
