Description

Technical Field

[0001] This invention belongs to the field of ton bag technology, specifically a ton bag packaging device. Background Technology

[0002] A ton bag is a flexible, medium-sized bulk container, convenient for transporting large quantities of bulk powdery materials. It features large volume, light weight, easy loading and unloading, and efficient use of space. However, because of its flexibility, ton bags are best suited for lifting during transport. If forklifts are needed for handling, relatively rigid supports (such as plastic supports) are generally required. But when unpacking and feeding are needed, the ton bags must be removed from the supports, a cumbersome process that hinders automation. Summary of the Invention

[0003] To address the aforementioned problems in existing technologies, the purpose of this invention is to provide a ton bag packaging device. When unpacking is required, the cap is pushed open to expose the feeding channel. Then, a bag-piercing knife is inserted through the feeding channel to puncture the ton bag, allowing the material inside to fall automatically. There is no need to remove the ton bag from the pallet before feeding, simplifying the process and facilitating production automation. The top surface of the pallet body is concave, providing more stable support for the ton bag. During feeding, the concave top surface guides the material inside the ton bag, directing it towards the feeding channel to ensure sufficient material falls. The PTFE bushing on the inner wall of the feeding channel has low friction, further facilitating smooth material flow. The overall structure of the device is simple and compact.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A ton bag packaging device includes a ton bag and a pallet. The pallet is used to support and connect the ton bag. The ton bag includes an inner bag and an outer bag. The inner bag is placed inside the outer bag, and the material is placed inside the inner bag. The pallet includes a pallet body and a cover. The pallet body has a feeding channel in the middle that runs through the thickness direction of the pallet body. The cover can be driven to close or open the feeding channel. The top surface of the pallet body is concave in the middle, and the ton bag directly contacts the top surface of the pallet body.

[0006] As a further improvement to the above technical solution:

[0007] The bottom surface of the pallet body is provided with multiple legs, which protrude from the bottom surface of the pallet body.

[0008] A slide is provided at the outlet of the unloading channel on the bottom surface of the pallet body. The slide protrudes from the bottom surface of the pallet body, the unloading channel passes through the center of the slide, and the cover slides on the slide.

[0009] The slide table is provided with two second slide grooves and / or two second slide rails. Along the length direction of the second slide grooves, the cross-section of the second slide grooves increases or decreases sequentially. Along the length direction of the second slide rails, the cross-section of the second slide rails increases or decreases sequentially.

[0010] Two second chutes are located on both sides of the material discharge channel outlet, and two second slide rails are located on both sides of the material discharge channel outlet.

[0011] The cover is provided with two first slide rails and / or two first slide grooves, the two first slide rails are respectively engaged with two second slide grooves, and the two first slide grooves are respectively engaged with two second slide rails.

[0012] The slide table has a cuboid outline, which includes a top surface, a bottom surface, and four side surfaces. The top surface of the slide table is fixedly connected to the bottom surface of the tray body. The outlet of the material unloading channel is located on the bottom surface of the slide table. The slide table is provided with two second slide grooves, which are respectively opened on two opposite side surfaces of the slide table and penetrate through the other two opposite side surfaces of the slide table.

[0013] The wall of the second chute includes a bottom surface and two side surfaces. The bottom surface is connected to the two side surfaces, which are the upper side surface and the lower side surface, respectively. The upper side surface and the lower side surface are perpendicular to the bottom surface. The plane containing the bottom surface is parallel to the center line of the feeding channel. The plane containing the upper side surface is parallel to the bottom surface of the slide table. The lower side surface and the upper side surface are not parallel.

[0014] Each second slide rail divides one end of the slide table into upper and lower parts. The lower part is the second slide rail, the bottom surface of which is part of the bottom surface of the slide table, and the lower side surface is the top surface of the second slide rail.

[0015] The cover also includes a cover plate and a baffle. The cover plate is a plate-shaped structure, and the baffle is a long strip-shaped plate-shaped structure. The baffle is perpendicular to the cover plate and connected to one side of the cover plate. A limiting block is provided on the bottom surface of the tray body. The baffle is located between the limiting block and the slide. When the cover moves to one end and the baffle contacts the limiting block, the cover is prevented from moving further in this direction, and the feeding channel is fully open. When the cover moves to the other end and the baffle contacts the slide, the cover is prevented from moving further in this direction, and the feeding channel is completely blocked by the cover plate.

[0016] The beneficial effects of this invention are:

[0017] (1) When it is necessary to unpack, push the cap open to expose the feeding channel, and then pierce the ton bag through the feeding channel with the bag-breaking knife. The material inside the ton bag will fall automatically. There is no need to remove the ton bag from the pallet before feeding. The process is simple and facilitates the automation of production.

[0018] (2) The top surface of the pallet body is concave to provide more stable support for the ton bag. When feeding, the concave top surface guides the material in the ton bag and guides the material to move towards the feeding channel, ensuring that the material in the ton bag falls down fully. The PTFE bushing on the inner wall of the feeding channel has low friction, which is conducive to the smooth falling of the material.

[0019] (3) The device has a simple and compact overall structure. Attached Figure Description

[0028] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0030] A ton bag packaging device, such as Figures 1-8 As shown, the device includes a ton bag 2 and a pallet 1. The pallet 1 supports and connects the ton bag 2, facilitating its transfer. The ton bag 2 includes an inner bag 21 and an outer bag 22, with the inner bag 21 nested inside the outer bag 22. Material is contained within the inner bag 21. Both the inner bag 21 and the outer bag 22 are flexible rather than rigid. Thus, when the inner bag 21 contains material, it expands due to the material filling; when the inner bag 21 is empty, both the inner bag 21 and the outer bag 22 collapse and compress. Preferably, the upper end of the inner bag 21 extends beyond the outer bag 22. The outer bag 22 has multiple straps 23, at least some of which have looped upper ends for easy lifting, and the lower ends of the straps 23 extend outwards for connection to the pallet 1.

[0031] Tray 1 Figures 2-8 As shown, the tray includes a tray body 11 and a cover 12. The overall outline of the tray body 11 is a cuboid. The length and width of the cuboid are basically equal, and the thickness of the cuboid is less than its length and width, so that the tray body 11 is a relatively thin cuboid.

[0032] Of the two opposing faces of the cuboid outline of the pallet body 11 perpendicular to its thickness direction, one is the top surface and the other is the bottom surface. The ton bag 2 is supported on the top surface. The center of the top surface is concave; preferably, the concave surface is part of a sphere. Further, in a projection plane perpendicular to the thickness direction of the pallet body 11, the projection of the top surface is a square or a rectangle, and the projection of the concave surface is a circle or an ellipse. When the projection of the top surface is a square, the projection of the concave surface is a circle, and this circle is internally tangent to the square projection of the top surface; when the projection of the top surface is a rectangle, the projection of the concave surface is an ellipse, and this ellipse is internally tangent to the rectangle projection of the top surface.

[0033] The bottom surface of the pallet body 11 is provided with a plurality of support legs 112, which protrude from the bottom surface of the pallet body 11 and are arranged at intervals on the bottom surface of the pallet body 11. Preferably, the plurality of support legs 112 are arranged along the edge of the bottom surface of the pallet body 11, with one support leg 112 at each of the four corners of the bottom surface of the pallet body 11 and one support leg 112 at the middle of each side of the bottom surface of the pallet body 11.

[0034] The pallet body 11 has a through-hole discharge channel 111 in the middle, which extends through the thickness of the pallet body 11 and is not obstructed by the support legs 112. The discharge channel 111 is used to allow material in the ton bag 2 to fall through the discharge channel 111. Preferably, the discharge channel 111 is located at the center of the pallet body 11, that is, on the top surface of the pallet body 11, and the discharge channel 111 is located at the lowest point of the concave surface.

[0035] Preferably, the bottom surface of the pallet body 11 is further provided with a cover 12, which can be driven to close or open the unloading channel 111. Specifically, a slide 113 is provided at the outlet of the unloading channel 111 on the bottom surface of the pallet body 11. The slide 113 protrudes from the bottom surface of the pallet body 11, and the unloading channel 111 passes through the center of the slide 113. The cover 12 is slidably mounted on the slide 113.

[0036] like Figures 4-7As shown, the slide table 113 is generally a thin cuboid, comprising a top surface, a bottom surface, and four side surfaces. The top surface of the slide table 113 is fixedly connected to the bottom surface of the tray body 11. The outlet of the unloading channel 111 is located on the bottom surface of the slide table 113. The slide table 113 is provided with two second slide grooves 1132, which are respectively opened on two opposite side surfaces of the slide table 113 and extend through the other two opposite side surfaces of the slide table 113. Therefore, each second slide groove 1132 effectively divides one end of the slide table 113 into upper and lower parts, with the lower part being the second slide rail 1131, the bottom surface of which is part of the bottom surface of the slide table 113. The two second slide grooves 1132 are arranged in parallel and are located on both sides of the unloading channel 111. The second chute 1132 is recessed into one side of the slide table 113, and its two ends extend to two other opposite sides along its length. The wall of the second chute 1132 includes a bottom surface and two side surfaces, with the bottom surface connecting to the two side surfaces. The two side surfaces are the upper side surface d and the lower side surface c, both of which are perpendicular to the bottom surface. The plane containing the bottom surface is parallel to the central axis of the feeding channel 111, the plane containing the upper side surface d is parallel to the bottom surface of the slide table 113, and the lower side surface c is not parallel to the upper side surface d, i.e., the lower side surface c is an inclined plane relative to the upper side surface d. The lower side surface c corresponds to the top surface of the second slide rail 1131.

[0037] The cover 12 and the slide 113 cooperate, such as Figure 8As shown, the cover 12 includes a cover plate 121, a baffle 122, a first slide rail 123, a first slide groove 124, a pusher wing 125, and a side baffle 126. The cover plate 121 is a plate-shaped structure, and the baffle 122 is a long strip-shaped plate-shaped structure, perpendicular to the cover plate 121, and connected to one side of the cover plate 121. The first slide rail 123 is a long strip-shaped block structure, and there are two first slide rails 123. The side baffle 126 is a long plate-shaped structure, and there are two side baffles 126. The two side baffles 126 are integrally connected to the two first slide rails 123 respectively, and the whole connected structure is a long strip-shaped structure with an L-shaped or "7"-shaped cross-section. The top surface b and bottom surface a of the first slide rail 123 are both perpendicular to the side baffle 126, but the top surface b and bottom surface a of the first slide rail 123 are not parallel. The side baffle 126 is perpendicular to the cover plate 121 and the baffle 122, and the two side baffles 126 are respectively connected to two opposite sides of the cover plate 121. One end of the side baffle 126 is perpendicularly connected to the baffle 122. The two first slide rails 123 are arranged parallel and spaced apart. One end of the first slide rail 123 is connected to the baffle 122, and the other end is overhanging. There is a gap between the first slide rail 123 and the cover plate 121. The top surface b of the first slide rail 123 is parallel to the cover plate 121, while the bottom surface a of the first slide rail 123 is not parallel to the cover plate 121. The bottom surface a of the first slide rail 123 is closer to the cover plate 121 than the top surface b of the first slide rail 123. The first slide rail 123 and the cover plate 121 are located on the same side of the baffle 122. Based on the above structure, the bottom surface a of the first slide rail 123, the side baffle 126, and the cover plate 121 form a groove, which is the first slide groove 124. The openings of the two first slide grooves 124 are arranged face to face. From the direction closer to the baffle 122 to the direction farther away from the baffle 122, the cross-section of the first slide groove 124 gradually increases. Two push wings 125 are provided. The push wings 125 are a single-piece structure. The two push wings 125 are integrally connected to the two side baffles 126 respectively. The push wings 125 are connected to the end of the side baffle 126 away from the baffle 122. The push wings 125 and the first slide rail 123 are located on both sides of the side baffle 126 respectively.

[0038] Based on the above structure, the cover 12 can cooperate with the slide table 113, and the cover 12 can slide on the slide table 113. Specifically, the two first slide rails 123 can be inserted into the two second slide grooves 1132 respectively, and the two second slide rails 1131 can be inserted into the two first slide grooves 124 respectively. After cooperation, the upper side d is in contact with the top surface b of the first slide rail 123, the lower side c is in contact with the bottom surface a of the first slide rail 123, and the two side baffles 126 cover the sides of the two second slide rails 1131 respectively. The cover plate 121 covers the bottom surface of the slide table 113, thereby blocking and closing the outlet of the feeding channel 111. When the cover 12 moves on the slide table 113, it moves along the length direction of the second slide groove 1132 or the first slide groove 124. When the pallet 1 is operating normally and being stored, the bottom surface of the slide 113 is parallel to the horizontal plane. The cover 12 and the slide 113 form an inclined or wedge-shaped fit, enabling a self-locking function. That is, the cover 12 will not move along the slide 113 under its own weight; a certain force must be applied to push the cover 12. This ensures that the cover 12 remains stable and does not move during transport, and that when the cover 12 is pushed, its movement is faster and smoother.

[0039] Based on the above structure and cooperation, the cover 12 will not slip off the slide table 113. Specifically, the slide rail and the slide groove will not disengage from each other, and the movement range of the cover 12 relative to the slide table 113 is limited, so that the cover 12 and the slide table 113 will not disengage. One end of the first slide groove 124 is blocked by the baffle 122, and a limiting block 114 is provided on the bottom surface of the tray body 11. The baffle 122 is located between the limiting block 114 and the slide table 113. Thus, when the cover 12 moves towards one end and one end of the baffle 122 of the cover 12 contacts the limiting block 114, the cover 12 is prevented from continuing to move in this direction, and at this time the feeding channel 111 is fully open; when the cover 12 moves towards the other end and the baffle 122 of the cover 12 contacts the slide table 113, the cover 12 is prevented from continuing to move in this direction, and at this time the feeding channel 111 is completely blocked by the cover 12.

[0040] Preferably, an automatic drive unit can be set up in the ton bag unpacking process to automatically push the cap 12 to move back and forth.

[0041] The pallet body 11 is also provided with multiple strapping holes 115. Preferably, each strapping hole 115 penetrates the same side of the pallet body 11, that is, the inlet and outlet of the strapping hole 115 are both on the same side of the pallet body 11. For ease of manufacturing, the pallet body 11 can be set as two interconnected layers. The strapping holes 115 of the upper layer penetrate its side and bottom surface, and the strapping holes 115 of the lower layer penetrate its side and top surface. When the two layers are stacked, the strapping holes 115 of the upper layer and the strapping holes 115 of the lower layer are connected to form a large strapping hole 115 with both the inlet and outlet on the side of the pallet body 11. At this time, the bottom opening of the strapping hole 115 of the upper layer is aligned with the top opening of the strapping hole 115 of the lower layer. Multiple strapping holes 115 are arranged at intervals along the circumference of the pallet body 11. The strapping holes 115 are used to tie the ton bag 2 to the pallet body 11 using straps 23, that is, the lower end of the strap 23 on the outer bag 22 passes through the strapping hole 115 and is then tied tightly.

[0042] Furthermore, the top and bottom surfaces of the tray body 11 are provided with multiple small anti-slip protrusions or anti-slip grooves.

[0043] Preferably, the inner wall of the feeding channel 111 is fitted with a PTFE (polytetrafluoroethylene) bushing, which is resistant to high temperature and has a low coefficient of friction, making it easy for materials to fall smoothly.

[0044] Based on the above structure, the ton bag 2 is supported and connected to a relatively rigid pallet 1 made of plastic or other materials. When it is necessary to unpack, the cap 12 is pushed open to expose the discharge channel 111. Then, the bag-breaking knife is inserted through the discharge channel 111 to puncture the ton bag 2, and the material inside the ton bag 2 will fall out automatically.

[0045] Finally, it is necessary to state that the above embodiments are only used to further illustrate the technical solution of the present invention in detail, and should not be construed as limiting the scope of protection of the present invention. Any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention shall fall within the scope of protection of the present invention.
