Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly to a glyphosate large-bag packaging machine. Background Art

[0002] Glyphosate is an effective active chemical component in many widely used herbicides. Glyphosate has no direct relation with genetically modified crops. Non-genetically modified crops also need to apply glyphosate herbicide. During the production process of glyphosate, a packaging machine is required to perform necessary packaging treatment on glyphosate materials.

[0003] However, the existing packaging machines for glyphosate production are usually small-bag packaging. The existing small-bag packaging equipment is not applicable to large-bag packaging. Small-bag packaging materials are directly packaged on the packaging machine after being folded from a coil. Due to size reasons, large bags cannot be installed with large-sized coils. Therefore, it is necessary to load the pre-processed large-bag packaging materials. Moreover, there is no positioning during the loading of packaging materials in the large-bag packaging process, which easily causes the bags to be skewed, resulting in the inclination of the packaging materials and affecting the bagging. When the product is discharged, the connection surface of the large-bag packaging material is in the same direction as the conveying direction, which will cause the position of the product on the conveyor belt to be uncertain, with poor consistency and affecting subsequent boxing. There is a lack of a continuous operation packaging equipment for glyphosate large bags on the market. Summary of the Invention

[0004] According to the above technical problems to be solved, a glyphosate large-bag packaging machine is provided.

[0005] To achieve the above object, the present invention discloses a glyphosate large-bag packaging machine, including a frame with a ladder. A conveying mechanism is horizontally installed at the bottom of the frame.

[0009] Furthermore, the filling mechanism includes a horizontally arranged first fixing plate and a feed pipe installed at the bottom of the feeding mechanism. The feed pipe is located at the center of the first fixing plate. A dust removal component is movably installed outside the feed pipe. The dust removal component is connected to the output end of a cylinder fixed on the first fixing plate to realize lifting. On both the front and rear sides of the first fixing plate at the bottom of the feed pipe, bag opening components are symmetrically installed. The bag opening components are located on both sides of the packaging material. The bag opening components include a bag opening cylinder fixed at the bottom of the first fixing plate and a connecting arm connected to the output end of the bag opening cylinder. A bag opening suction cup is installed at a position where the connecting arm is close to the feed pipe. Second jaws are arranged on both the left and right sides of the bag opening components.

[0010] Furthermore, the sealing mechanism includes a second fixing plate installed in the same direction as the filling mechanism. A degassing component is installed at the center of the second fixing plate. The degassing component includes a lifting guide rail installed on the top of the second fixing plate.

The two ends of the flat pipe structure are chamfered to form a pointed nozzle. Third jaws are arranged on both the left and right sides of the degassing component. Sealing plates are respectively installed on the tops of the third jaws. The outer sides of the sealing plates are connected to a cylinder component. A bent guide plate is installed on the end face of the sealing mechanism close to the filling mechanism. A cylinder slide rail component is arranged on the top of the third jaw far from the guide plate. The third jaw on the right and the cylinder slide rail component form a bag wiping mechanism.

[0011] Further, the steering mechanism includes a lifting cylinder assembly and a rotating cylinder assembly disposed below the lifting cylinder assembly. A clamping jaw cylinder assembly is installed at the bottom of the rotating cylinder assembly, and a clamping plate is installed at the output end of the clamping jaw cylinder assembly.

The clamping and conveying assembly includes a mounting rack arranged at the top of the roller assembly. Two sets of bag clamping mechanisms are arranged on one side of the mounting rack close to the conveying mechanism. A spacing of one working station is arranged between the two sets of bag clamping mechanisms. The output end of the bag clamping cylinder located on the upper layer is connected to a long clamping plate, and a through hole is formed in the center of the long clamping plate through which an edge degassing pipe passes. The output end of the bag clamping cylinder located on the lower layer is connected to a wide clamping plate for clamping the packaging material. The belt drive assembly is located below the steering mechanism. A tray with a lifting function is arranged directly below the conveying mechanism, the filling mechanism, and the sealing mechanism.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] An embodiment of the present invention is as follows Figure 1 and Figure 2 As shown, a conveying mechanism 20 is horizontally installed at the bottom of the frame 10. A pedal capable of weighing is provided at the top of the frame. Along the conveying direction inside the frame 10, a filling mechanism 50, a sealing mechanism 60, and a turning mechanism 70 are sequentially arranged on the top of the conveying mechanism 20. An upper bagging mechanism 30 is arranged inside the frame 10 behind the filling mechanism 50. The upper bagging mechanism 30 is connected to the filling mechanism 50 through a swing arm mechanism 40. An inlet mechanism is arranged directly above the filling mechanism 50 at the top of the frame 10. The inlet mechanism includes a hopper 11 and an automatic metering unit 12 arranged at the bottom of the hopper 11. The automatic metering unit 12 is connected to the filling mechanism 50. During the upper bagging process, it is positioned by a suction cup. The first clamping jaw grabs the position of the packaging material sorted on the whole bag mechanism to avoid deviation. The swing arm mechanism clamps and flips the sorted packaging material by 90° and moves it to directly below the filling mechanism for subsequent filling and sealing operations. After sealing, the product is rotated by 90° through the turning mechanism so that the part with a larger area faces the conveyor belt and falls, ensuring the consistency of the product during the conveying process, realizing the continuous packaging operation for large bags of glyphosate, improving production efficiency, and having a high production yield.

[0030] As Figure 3 and Figure 4 As shown, the upper bagging mechanism 30 includes a placement table 31 located behind the sealing mechanism 60. A whole bag mechanism 32 is installed on the side of the placement table 31 behind the filling mechanism 50. A bag grasping mechanism 33 is arranged above the whole bag mechanism 32. A first guide rod 312 is installed at the bottom of the placement table 31 and the whole bag mechanism 32. A push bag cylinder assembly 313 is movably installed on the first guide rod 312. The push bag cylinder assembly includes a horizontal cylinder structure installed in the same direction as the first guide rod and a vertical cylinder structure installed at the output end of the horizontal cylinder structure. The output end of the push bag cylinder assembly 313 is connected to a push bag rod 311 vertically arranged through the placement table 31. A waist-shaped groove corresponding to the position of the push bag rod 311 is opened on the surface of the placement table 31. The whole bag mechanism 32 includes a table surface fixed to the side of the placement table 31. A conveyor belt 321 perpendicular to the first guide rod 312 is installed at the center of the table surface. Whole bag plates 322 are symmetrically arranged on the left and right sides of the conveyor belt 321. The bottom of the whole bag plates 322 on the same side is connected to a whole bag cylinder through a connecting plate to complete the synchronous clamping and unfolding action. A baffle 34 is arranged on one side of the table surface close to the filling mechanism 50.

[0031] The bag grasping mechanism 33 includes a first transverse movement module 331 installed in the same direction as the first guide rod 312. A first gripper 332 is installed on the slider at the bottom of the first transverse movement module 331. The first gripper 332 is installed offset from the lower bag shaping plate 322 to ensure no interference during movement. At one end of the first transverse movement module 331 close to the placing table 31, a bag sucking mechanism 333 is installed. The bag sucking mechanism 333 includes a connecting rod fixed on the end face of the first transverse movement module 331. A lifting cylinder is vertically installed on the connecting rod. The output end of the lifting cylinder is installed with suction cups corresponding to the number of the first grippers 332. The suction cups are located on the top of the placing table 31. The suction cups descend to adsorb the packaging material on the side of the placing table close to the bag shaping mechanism and then rise. The first gripper moves to the position of the packaging material, clamps it and then resets to place the packaging material on the surface of the conveyor belt. Subsequently, the bag shaping plate shapes and positions the packaging material.

[0032] As Figure 5 and Figure 6 shown, the swing arm mechanism 40 is installed on the frame 10 between the bag shaping mechanism 32 and the filling mechanism 50. The swing arm mechanism 40 includes a rotating shaft 41 arranged perpendicular to the conveying direction of the conveyor belt 321. A driving motor is installed at one end of the rotating shaft 41. A swing arm 42 is installed on the rotating shaft. First grippers are oppositely installed at the end of the swing arm 42. The driving motor makes the swing arm 42 rotate within a range of 90°. The packaging material is grabbed from the bag shaping mechanism 32 to directly below the filling mechanism 50 by the first grippers. After the packaging material is sorted out at the bag shaping mechanism, the swing arm mechanism can move the packaging material to the bottom of the filling mechanism, which is suitable for loading large-sized packaging materials.

[0033] As Figure 7 and Figure 8As shown, the stuffing mechanism 50 includes a horizontally arranged first fixed plate 51 and a feed pipe 52 installed at the bottom of the feeding mechanism. The feed pipe is a telescopic structure. The feed pipe 52 is located at the center of the first fixed plate 51. A dust removal component 53 is movably installed outside the feed pipe 52. The dust removal component 53 is connected to the output end of a cylinder fixed on the first fixed plate 51 to realize lifting and lowering. The dust removal component moves up and down synchronously with the movable section of the feed pipe. The dust removal component adsorbs dust during the stuffing process to avoid generating dust and other factors that affect the production environment. On the front and rear sides of the first fixed plate 51 at the bottom of the feed pipe 52, bag opening components 54 are symmetrically installed. The bag opening components 54 are located on both sides of the packaging material. The bag opening component 54 includes a bag opening cylinder 541 fixed at the bottom of the first fixed plate 51 and a connecting arm 542 connected to the output end of the bag opening cylinder 541. A bag opening suction cup 543 is installed at a position where the connecting arm 542 is close to the feed pipe 52. Second clamping claws 55 are arranged on the left and right sides of the bag opening component 54. The surface of the second clamping claws is provided with corrugated claw teeth to ensure the clamping stability. A conveyor belt component 56 surrounding the feed pipe 52 is arranged on the top of the first fixed plate 51. The belt of the conveyor belt component 56 is fixedly connected to the fixed blocks at the top of the second clamping claws 55. The fixed blocks are slidably installed on the slide rails 57 at the top of the first fixed plate 51. The slide rails 57 are symmetrically arranged on the front and rear sides of the feed pipe 52 to ensure the moving stability of the second clamping claws 55. The fixed blocks at the tops of the two groups of second clamping claws are respectively arranged on the front and rear sides of the conveyor belt of the conveyor belt component. When the conveyor belt component operates, the two groups of second clamping claws can perform opposite or reverse actions to complete the bag wiping action. When the swing arm mechanism moves the packaging material to the bottom of the stuffing mechanism, the second clamping claws clamp the bag mouth. The conveyor belt component operates to complete the bag wiping and open the bag mouth. The feed pipe descends to complete the stuffing and then resets. The third clamping claws reset. The transfer of the packaging material is completed through the clamping and conveying component on the conveying mechanism.

[0034] As Figure 9 and Figure 10As shown, the sealing mechanism 60 includes a second fixed plate 61 installed in the same direction as the filling mechanism 50. A degassing component 62 is installed at the center of the second fixed plate 61. The degassing component 62 includes a lifting guide rail 621 installed on the top of the second fixed plate 61. A degassing pipe 622 is installed on the slider of the lifting guide rail 621. The bottom of the degassing pipe 622 is of a flat pipe structure, and the two ends of the flat pipe structure at the end are chamfered to form a spout. Third clamping jaws 63 are arranged on the left and right sides of the degassing component 62. Tooth structures with a density greater than that of the second clamping jaws are arranged on the surfaces of the third clamping jaws to ensure the flatness of the bag mouth before sealing. Sealing plates 64 are respectively installed at the tops of the third clamping jaws 63. A thermocouple is connected to the top of the sealing plate. The packaging material is sealed by electric heating. The specific sealing structure belongs to the working medium attempts in this field and will not be elaborated here. The outside of the sealing plate 64 is connected to a cylinder assembly. A high-temperature-resistant bearing is arranged between the sealing plate and the cylinder assembly. A bent guide plate is installed on one end face of the sealing mechanism 60 close to the filling mechanism 50. A cylinder slide rail assembly 65 is arranged on the top of the third clamping jaw 63 far from the guide plate. The third clamping jaw 63 on the right and the cylinder slide rail assembly 65 form a bag smoothing mechanism. When the packaging material moves from the filling mechanism to the right, the degassing component is at the topmost position. The packaging material reaches directly below the sealing mechanism after passing through the guide plate on the left side of the sealing mechanism. The bag mouth is clamped by the third clamping jaws. The third clamping jaw on the right moves towards the third clamping jaw on the left through the cylinder slide rail assembly to open the bag mouth and complete the bag smoothing action. The degassing component descends to insert the flat pipe at the bottom of the degassing pipe into the packaging material to complete degassing. After degassing is completed, the degassing pipe rises, and the third clamping jaws reset. The sealing plate completes the sealing of the packaging material.

[0035] As Figure 11 shown, the turning mechanism 70 includes a lifting cylinder assembly 71 and a rotating cylinder assembly 72 arranged below the lifting cylinder assembly 71. A clamping jaw cylinder assembly 73 is installed at the bottom of the rotating cylinder assembly 72. A clamping plate is installed at the output end of the clamping jaw cylinder assembly 73. The length of the clamping plate is greater than 50% of the length of the packaging material. The lifting cylinder assembly is used to adjust the height to avoid interference during the movement of the packaging material. The rotating cylinder assembly rotates the position where the packaging surface of the original packaging material faces directly forward by 90°, so that the packaging surface of the packaging material faces the conveying direction, ensuring that the bags can maintain consistency between bags when the packaging material falls on the belt drive assembly, which is convenient for subsequent packing.

[0036] As Figure 12As shown, the conveying mechanism 20 includes a chain drive assembly 21 and a belt drive assembly 22. At the center bottom of the chain drive assembly 21, a second transverse movement module arranged in the same direction as the conveying direction is installed. A second guide rod 23 is arranged outside the chain drive assembly 21. The second transverse movement module includes a roller assembly 24 movably installed on the second guide rod 23. At the top of the roller assembly 24, there is a clamping and conveying assembly 25 symmetrically arranged above the conveying mechanism 20. After the clamping and conveying assembly clamps the packaging material, power is provided by the chain drive assembly, and it reciprocates on the second guide rod through the roller assembly to realize the transfer of products between workstations. The clamping and conveying assembly 25 includes a mounting frame arranged at the top of the roller assembly 24. On one side of the mounting frame close to the conveying mechanism 20, there are two groups of bag clamping mechanisms. There is a spacing of one workstation between the two groups of bag clamping mechanisms. The output end of the clamping cylinder located in the upper layer is connected to a long clamping plate 251. A through hole is opened in the center of the long clamping plate to facilitate the passing of the air extraction pipe 622. The output end of the clamping cylinder located in the lower layer is connected to a wide clamping plate 252 for clamping the packaging material. The long clamping plate is used for clamping the bag mouth, and the wide clamping plate is used for clamping the bag body. The belt drive assembly 22 is located below the steering mechanism 70. A tray 26 with a lifting function is arranged directly below the conveying mechanism 20, the filling mechanism 50, and the sealing mechanism 60. When the bag clamping mechanism on the left clamps the packaging material below the filling mechanism, at this time, the bag clamping mechanism on the right is located below the sealing mechanism. The clamping and conveying assembly moves to the right to move the packaging material below the sealing mechanism. At this time, the bag clamping mechanism on the right moves the packaging material originally located below the sealing mechanism below the steering mechanism.

[0037] The following points need to be explained: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected. The terms "upper", "lower", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the object being described changes, the relative position relationship may change. Second, in this article, relational terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.
