Description

Technical Field

[0001] The invention relates to the field of ton bags, and in particular to a fully automatic ton bag unpacking machine. Background Art

[0002] Ton bag is a flexible transport packaging container, generally made of polyester fibers such as polyolefins and polyethylene. It has the characteristics of simple structure, light weight, foldability, small space occupied by empty space, and low price. Ton bag can be equipped with a crane or forklift to realize containerized unit transportation. It can be widely used in the packaging of various powdery, granular and blocky items such as chemicals, building materials, plastics and minerals.

[0003] The existing ton bag unpacking is mostly done manually. The crane drives the lifting hoist to the designated position, and then the ton bag is moved to the designated unpacking area by the lifting hoist. The workers manually unpack the ton bag. In this process, since the ton bag is in the lifted state, materials are piled up at the bottom, making it difficult for the workers to unpack, which wastes overall manpower and material resources and reduces the overall unpacking efficiency. At the same time, some materials will not be discharged from the ton bag during the discharge process, which will cause a lot of material waste.

[0004] In summary, the above structure wastes manpower and material resources in the actual unpacking process, reduces the overall unpacking efficiency, and after the unpacking is completed, some materials will still not be discharged in the ton bag, thus causing a large amount of material waste. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a fully automatic ton bag unpacking machine to solve the technical problem that the above structure wastes manpower and material resources in the actual unpacking process, and after unpacking is completed, some materials will still remain in the ton bag, thereby causing a large amount of material waste.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a fully automatic ton bag unpacking machine comprises a box body, a conveying plate is slidably arranged on the inner side of the box body, one end of the conveying plate is connected to a gear rod, and a crank is rotatably connected to one side of the gear rod through gear meshing, and the other end of the crank is connected to a crushing wheel, a slide groove is arranged on the top of the box body, and a grabbing mechanism is slidably arranged in the slide groove, a slide plate is arranged on the top of the grabbing mechanism, a top plate is elastically arranged on the top of the slide plate, a plug rod is symmetrically arranged on the bottom of the top plate, and one end of the plug rod passes through the slide plate, a plug hole for the plug rod to be inserted is opened in the slide groove, an array of tooth block groups is equidistantly arranged on one side of the plug rod, and a fixed gear is meshed on one side of the tooth block group, a worm gear is transmission-arranged on one side of the fixed gear, and a racket rod is installed at the bottom of the worm gear.

[0007] By adopting the above technical solution, the crank is driven to rotate under the meshing with the driven gear during transportation, and the cutting work on the front end of the ton bag is completed at this time. When the ton bag continues to move to one side through the grabbing mechanism, the crushing wheel passively contacts the two sides of the ton bag, thereby completing the unpacking of the ton bag during the movement. As the gravity of the ton bag itself will gradually decrease, the top plate will drive the insertion rod to slide upward under the action of the elastic component. Therefore, with the cooperation of the worm wheel and the worm, the ton bag is continuously beaten to ensure that all the materials in the ton bag are discharged.

[0008] The present invention is further configured such that a driving slider is slidably arranged in the slide groove and is connected to the slide plate at the top of the driving slider.

[0009] By adopting the above technical solution, the driving slider will slide back and forth in the slide groove, thereby driving the slide plate and the grabbing mechanism at the bottom to move, thereby completing the mobile transportation of the ton bag.

[0010] The present invention is further configured such that a side wall of the box body is provided with a slot for the conveying plate to slide, and a gear rod is slidably arranged in the slot.

[0011] By adopting the above technical solution, the conveying plate drives the ton bag to slide horizontally on the inner side of the box body under the action of the slot. At the same time, the conveying plate also drives the gear rod to move in the slot to ensure the stability of subsequent crushing wheel adjustment.

[0012] The present invention is further configured such that the grasping mechanism comprises a clamping claw, a cylinder and a guide driving rod, the output end of the cylinder is connected to the clamping claw, and the guide driving rod is installed on the top of the clamping claw.

[0013] By adopting the above technical solution, the claw is driven downward to the top of the ton bag under the action of the cylinder, and the claw is ensured to slide in the vertical direction through the guide drive rod. The claw is subsequently driven to complete the grabbing of the ton bag, thereby accelerating the overall grabbing efficiency of the ton bag.

[0014] The present invention is further configured such that a worm is connected to one side of the fixed gear, and a worm wheel is rotatably arranged on one side of the worm, one end of the fixed gear is connected to a torsion spring, and a tooth block is partially arranged on the fixed gear itself.

[0015] By adopting the above technical scheme, in the process of the fixed gear rotating through the tooth block group, the worm will rotate accordingly, and through the cooperation of the worm and the worm wheel, it is realized to drive the racket at the bottom of the worm wheel to rotate at a certain angle. At the same time, since the fixed gear is connected to the torsion spring, in the process of the tooth block group driving the fixed gear to rotate, the gap between the two groups of tooth block groups allows the fixed gear to reset and rotate, and the fixed gear is partially provided with tooth blocks. In the process of the insertion rod moving downward through the insertion hole, the fixed gear itself will not rotate, and the fixed gear will only rotate accordingly when the insertion rod is reset upward.

[0016] The present invention is further configured such that an elastic component is symmetrically arranged on the top of the slide plate, and the other end of the elastic component is connected to the top plate.

[0017] By adopting the above technical solution, when the ton bag is grabbed by the grabbing mechanism, the top plate slides downward due to the action of the ton bag's own gravity, thereby completing the compression of the elastic component at the bottom. In the subsequent discharge process, the top plate will drive the insertion rod to reset and slide upward due to the resetting action of the elastic component itself.

[0018] The present invention is further configured such that a driving gear is meshed on one side of the gear rod, and a driven gear is meshed on one side of the driving gear, and the top of the driven gear is connected to the crank.

[0019] By adopting the above technical solution, when the gear rod moves following the conveying plate, it will drive the driving gear on one side to rotate. Through the meshing action between the driving gear and the driven gear, the driven gear drives the crank to rotate, thereby completing the adjustment of the crushing wheel.

[0020] The present invention is further configured such that the outer wall of the racket rod is provided with a flexible protective sleeve.

[0021] By adopting the above technical solution, the flexible protective cover can prevent the racket rod from directly contacting the outer wall of the ton bag. The flexible protective cover can also increase the contact area between the racket rod and the ton bag, further improving the discharge effect during the beating process of the racket rod.

[0022] The present invention is further configured such that an array of micro-protrusions are provided on the top of the conveying plate, and the contact surface between the conveying plate and the card slot is configured to be smooth.

[0023] By adopting the above technical solution, the micro-protrusions on the top of the conveying plate can easily increase the friction between the ton bag and the conveying plate, preventing the ton bag from shifting at the top of the conveying plate during transportation. At the same time, the smooth setting between the slot and the conveying plate effectively reduces the sliding friction between the two, making it easier for the subsequent conveying plate to follow the ton bag after discharge for resetting.

[0024] The present invention is further configured such that the crushing wheel is located at the inner bottom of the box body, and the rappel rod is located between the crushing wheel and the grabbing mechanism.

[0025] By adopting the above technical solution, the crushing wheel at the bottom is convenient for crushing the bottom of the ton bag, which is convenient for subsequent material discharge. At the same time, the beating rod is located in the middle position of the ton bag, and the overall discharge effect is further improved during the beating process.

[0026] In summary, the present invention mainly has the following beneficial effects:

[0027] 1. The present invention places the to-be-unpacked ton bag on the top of the conveying plate, and then grabs the top of the ton bag through the grabbing mechanism, and drives the ton bag to slide to one side of the box body under the action of the driving slider. When the ton bag moves to the crushing wheel, the gear rod on one side of the conveying plate will mesh with the driving gear, and then drive the crank to rotate under the meshing with the driven gear during transportation, and then the cutting work of the front end of the ton bag is completed, and then the crushing wheels are located on both sides of the ton bag. In the process of the ton bag continuing to move to one side through the grabbing mechanism, the crushing wheels passively contact the two sides of the ton bag, so that the bottom of the ton bag is cut into three quarters, so that the unpacking of the ton bag is completed during the movement. This process speeds up the overall unpacking efficiency and reduces the unpacking burden of the staff;

[0028] 2. The present invention is provided with a top plate sliding on the top of the grabbing mechanism, and a plug rod is connected to the driving slider penetrating through the top of the top plate. After the ton bag is unpacked, the grabbing mechanism moves the ton bag to the designated position for unloading. At this time, the plug rod will be inserted into the insertion hole in the slide slot. As the materials in the ton bag are gradually released, the gravity of the ton bag itself will gradually decrease. At this time, the top plate will drive the plug rod to slide upward under the action of the elastic component. An array of tooth block groups are equidistantly arranged on one side of the plug rod. At the same time, the fixed gear is rotated by a torsion spring. Therefore, under the action of the tooth block group, the fixed gear itself will reciprocate. Under the cooperation of the worm wheel and the worm, the slapping rod itself will reciprocate, thereby continuously slapping the ton bag to ensure that all the materials in the ton bag are discharged, effectively preventing the waste of materials.

DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] The following describes an embodiment of the present invention based on its overall structure.

[0040] Embodiment 1

[0041] A fully automatic ton bag unpacking machine, such as Figure 1-Figure 8 As shown, it includes a box body 1, a top plate 2, a sliding mechanism, a grabbing mechanism 6, a crushing mechanism and a discharging mechanism. The staff places the ton bag to be unpacked on the top of the conveying plate 21. A slot 20 for the conveying plate 21 to slide is provided on the side wall of the box body 1. The conveying plate 21 drives the ton bag to slide horizontally to the top of the grabbing mechanism 6 on the inner side of the box body 1 under the action of the slot 20. A slide groove 7 is provided on the top of the box body 1, and a grabbing mechanism 6 is slidably provided in the slide groove 7. The top of the ton bag is grabbed under the action of the grabbing mechanism 6. A slide plate 18 is provided on the top of the grabbing mechanism 6, wherein the top plate 2 is elastically provided on the top of the slide plate 18. At this time, the top plate 2 slides downward under the action of the ton bag's own gravity, and then the ton bag is moved to one side through the slide groove 7. A gear rod 15 is slidably provided in the slot 20, and is connected to the gear rod 15 at one end of the conveying plate 21.

[0042] When the grabbing mechanism 6 drives the ton bag to move to the crushing wheel 10, one side of the gear rod 15 is meshed with the driving gear 16, and one side of the gear rod 15 is meshed with the driving gear 16, and one side of the driving gear 16 is meshed with the driven gear 17, and the top of the driven gear 17 is connected to the crank 4. In the process of continuing to move, the gear rod 15 will drive the driving gear 16 on one side to rotate. Through the meshing action between the driving gear 16 and the driven gear 17, the driven gear 17 drives the crank 4 to rotate, thereby completing the cutting work on the front end of the ton bag. After the driven gear 17 drives the crushing wheel 10 to adjust, the crushing wheel 10 is located on both sides of the ton bag. In the process of the ton bag continuing to move to one side through the grabbing mechanism 6, the crushing wheel 10 passively contacts the two sides of the ton bag, thereby cutting three quarters of the bottom of the ton bag, thereby completing the unpacking of the ton bag during the movement. This process speeds up the overall unpacking efficiency and reduces the unpacking burden of the staff.

[0043] When the bag is packed with the bag materials, the bag 3 will be easily packed with the bag materials in the bag.

[0044] See also Figure 1 and Figure 3 A driving slider 19 is slidably provided in the slide groove 7, and the top of the driving slider 19 is connected to the slide plate 18. Under the action of the driving slider 19, it will slide back and forth in the slide groove 7, thereby driving the slide plate 18 and the grabbing mechanism 6 at the bottom to move, thereby completing the movement and transportation of the ton bag, and the insertion rod 3 penetrates the slide plate 18 and the driving slider 19, so when it moves to the socket 8 in the slide groove 7, the insertion rod 3 will be stuck in the inside of the socket 8.

[0045] See also Figure 1 and Figure 4The grabbing mechanism 6 includes a claw 601, a cylinder 602 and a guide driving rod 603. The claw 601 is connected to the output end of the cylinder 602, and the guide driving rod 603 is installed on the top of the claw 601. Under the action of the cylinder 602, the claw 601 is driven to move downward to the top of the ton bag. The guide driving rod 603 ensures that the claw 601 slides in the vertical direction, and then drives the claw 601 to complete the grabbing of the ton bag, thereby accelerating the overall grabbing efficiency of the ton bag.

[0046] See also Figure 1 and Figure 7 An elastic component 9 is symmetrically arranged on the top of the slide plate 18, and the other end of the elastic component 9 is connected to the top plate 2. When the ton bag is grabbed by the grabbing mechanism 6, the top plate 2 slides downward under the action of the ton bag's own gravity, thereby completing the compression of the elastic component 9 at the bottom. In the subsequent discharge process, the top plate 2 will drive the insertion rod 3 to reset and slide upward under the reset action of the elastic component 9 itself.

[0047] See also Figure 1 , Figure 2 and Figure 5 A flexible protective cover is provided on the outer wall of the racket bar 5, which can prevent the racket bar 5 from directly contacting the outer wall of the ton bag. The flexible protective cover can also increase the contact area between the racket bar 5 and the ton bag, further improving the discharge effect of the racket bar 5 during the beating process. At the same time, the crushing wheel 10 is located at the inner bottom of the box body 1, and the racket bar 5 is between the crushing wheel 10 and the grabbing mechanism 6. The crushing wheel 10 at the bottom is convenient for crushing the bottom of the ton bag, which is convenient for discharging subsequent materials. At the same time, the racket bar 5 is in the middle position of the ton bag, and the overall discharge effect is further improved during the beating process.

[0048] Embodiment 2

[0049] like Figure 5The fully automatic ton bag unpacking machine shown in the figure has an overall structure similar to that of the first embodiment, wherein a worm 12 is connected to one side of the fixed gear 11, and a worm wheel 14 is rotatably arranged on one side of the worm 12. In the process of the fixed gear 11 rotating through the tooth block group 13, the worm 12 will rotate accordingly. Through the cooperation of the worm 12 and the worm wheel 14, the flapper 5 at the bottom of the worm wheel 14 is driven to rotate at a certain angle. At the same time, since the fixed gear 11 is connected to the torsion spring, in the process of the tooth block group driving the fixed gear 11 to rotate, the gap between the two groups of tooth block groups 13 allows the fixed gear to reset and rotate, thereby realizing the continuous flapping of the outer wall of the ton bag during the rotation. In addition, the fixed gear 11 is partially provided with tooth blocks. In the process of the insertion rod 3 moving downward through the insertion hole 8, the fixed gear 11 itself will not rotate. Only when the insertion rod 3 is reset upward, the fixed gear 11 will rotate accordingly. In this process, the stability of the flapper 5 in the rotation inside the box body 1 is guaranteed.

[0050] The working principle of the present invention is as follows: when in use, the ton bag to be unpacked is placed on the top of the conveying plate 21, and then the grabbing mechanism 6 is moved to the top of the ton bag under the action of the driving slider 19, and the top of the ton bag is grabbed under the action of the claw 601, and then the grabbing mechanism 6 drives the ton bag to slide to the crushing wheel 10, and then continues to move, and the toothed rod 15 at one end of the conveying plate 21 drives the driving gear 16 to rotate, and the crank 4 drives the crushing wheel 10 to rotate a certain angle through the engagement with the driven gear 17, thereby completing the cutting of the front end of the ton bag, and at this time the crushing wheel 10 rotates to both sides of the ton bag, and when the grabbing mechanism 6 drives the ton bag to continue to move, the crushing wheel 10 is in passive contact with both sides of the ton bag, thereby causing the bottom of the ton bag to be cut in three quarters, thereby achieving the unpacking of the ton bag during the movement;

[0051] After the ton bag is unpacked, the grabbing mechanism 6 continues to move, so that the ton bag is moved to the specified position, and then the insertion rod 3 at the bottom of the top plate 2 is inserted into the insertion hole 8 under the action of the gravity of the ton bag. Since an array of tooth block groups 13 are equidistantly arranged on one side of the insertion rod 3, during the discharge of the ton bag, the self-gravity of the ton bag will gradually decrease. At this time, under the action of the elastic component 9, the top plate 2 drives the insertion rod 3 to slide upward. At this time, the tooth block group 13 will drive the fixed gear 11 to rotate. Since the fixed gear 11 is connected by a torsion spring, the worm gear 14 and the worm 12 cooperate to make the slapping rod 5 itself reciprocate, thereby continuously slapping the ton bag to ensure that all the materials in the ton bag are discharged, effectively preventing the waste of materials.

[0052] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention.
