Description

Technical Field

[0001] The present invention relates to the technical field of bag turning mechanisms, and more specifically to a large-sized canvas bag turning structure. Background Art

[0002] A canvas bag is a sturdy and durable packaging bag with a strong bearing capacity, having a large thickness and weight. However, when a large-sized canvas bag needs to be turned over during use, it can be very troublesome. In certain application scenarios, to ensure that there is no residue inside the canvas bag, it is necessary to turn the canvas bag inside out to fully expose the interior and ensure no remaining items. At the same time, the canvas bag is sturdy and durable and suitable for repeated use, so the inside-out turning should be carried out without damaging the canvas bag.

[0003] Currently, the inside-out turning of canvas bags is basically carried out manually. However, manual turning often fails to turn over completely, resulting in the retention of internal items and documents. If thorough turning is required, it will take more time and the efficiency is low. Moreover, in some special industries, it is necessary to minimize the participation of personnel, such as the transportation and destruction processes of important documents. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a large-sized canvas bag turning structure to solve the technical problems in the prior art that manual turning of canvas bags is prone to incomplete turning and low efficiency, and is not suitable for use in some special industries.

[0005] To solve the above technical problems, the present invention provides a large-sized canvas bag turning structure, which includes side plates, a bottom plate, and a top plate. The top plate is connected to the side plates, the bottom plate is slidably connected to the side plates and is located below the top plate. The bottom plate is connected with a first driving mechanism for driving the bottom plate to slide towards or away from the top plate. The bottom end of the top plate is connected with a fixed plate and a moving plate, and the top plate is connected with a second driving mechanism for driving the moving plate to move towards or away from the fixed plate. The bottom plate is connected with a bag turning component. When the bag turning component moves upward, it can move between the fixed plate and the moving plate. The bag turning component includes a corner supporting power plate, two columns, and two corner supporting blocks. The two columns are vertically connected to the bottom plate, and each column is rotatably connected with a corner supporting block, and the rotation center axis of the corner supporting block is arranged along the sliding direction of the moving plate. The corner supporting power plate is movably connected between the two columns. The turning structure further includes a third driving mechanism for driving the corner supporting power plate to move up and down. When the corner supporting power plate moves upward, it abuts against the two corner supporting blocks and causes the two corner supporting blocks to rotate away from each other. A reset mechanism for causing the two corner supporting blocks to close is connected to the two corner supporting blocks.

[0006] After adopting the above structure, the large-sized sailcloth bag turning structure of the present invention has the following advantages: The fixing plate and the moving plate are used as the bag-sleeving part. The sailcloth bag is sleeved on the fixing plate and the moving plate from bottom to top by a manipulator. Then, the moving plate moves away from the fixing plate, causing the sailcloth bag to expand. At this time, the turning component moves upward, and the two corner-supporting blocks rise and turn the sailcloth bag over. At this time, the turned-over sailcloth bag is sleeved on the two corner-supporting blocks. Then, the corner-supporting power plate moves upward, causing the two corner-supporting blocks to rotate away from each other, thereby further propping up the bottom of the sailcloth bag, ensuring that the sailcloth bag is turned over thoroughly and avoiding the residue of items and documents. It not only has high efficiency, but also does not require manual operation during the turning process, reducing personnel participation and being suitable for some special industries that require confidentiality.

[0007] As an improvement, the distribution direction of the two columns is perpendicular to the moving direction of the moving plate. The two sides of the corner-supporting power plate are slidably connected to the two columns. The front and rear end faces of the two corner-supporting blocks are flush. The third driving mechanism is connected to the columns or the bottom plate. With this structure, the up-and-down movement of the corner-supporting power plate is more stable.

[0008] As an improvement, both sides of the corner-supporting power plate are provided with first inclined surfaces that slope upward from bottom to top and inward toward the corner-supporting power plate. The upper ends of the two first inclined surfaces meet to form the top of the corner-supporting power plate, and the top is located below the two corner-supporting blocks. Both lower ends of the two corner-supporting blocks are provided with second inclined surfaces that slope upward from bottom to top in the direction of approaching the other corner-supporting block. With this structure, when the corner-supporting power plate moves upward, the rotation of the two corner-supporting blocks can be synchronized, ensuring that the bottom of the sailcloth bag can be stably propped up.

[0009] As an improvement, the reset mechanism includes an elastic band. The elastic band is connected to the upper ends of the two corner-supporting blocks. When the corner-supporting power plate moves downward, the elastic band makes the opposite end faces of the two corner-supporting blocks stick together. With this structure, the elastic band is used to make the corner-supporting blocks close together when the corner-supporting power plate retracts.

[0010] As an improvement, a protruding rounded corner is provided at the upper end of each corner-supporting block and at the corner far from the other corner-supporting block. With this structure, when the corner-supporting blocks rise, the two corners of the sailcloth bag can be propped up, and further, when the corner-supporting blocks rotate, the bottom of the sailcloth bag can be propped up, ensuring that the sailcloth bag is turned over thoroughly.

[0011] As an improvement, air outlets are provided on the two opposite end faces of the fixing plate and the moving plate. The air outlets are connected to a blower, and the air outlets are arranged obliquely downward toward the inside of the fixing plate and the moving plate. With this structure, the blower and the air outlets are used to blow off the residual items and documents on the sailcloth bag after the sailcloth bag is turned over, ensuring no residue.

[0012] As an improvement, a first guide groove is provided vertically on the side plate, and a protruding part is connected to the bottom plate and the protruding part is slidably connected in the first guide groove. With this structure, the movement of the bottom plate is more stable.

[0013] As an improvement, a second guide groove is provided on the top plate, and the movable plate is connected to the movable sub-plate through a connecting part. The movable sub-plate is located on the upper end surface of the top plate, the connecting part is slidably connected in the second guide groove, and the second driving mechanism is connected to the movable sub-plate; this structure makes the movement of the movable plate more stable.

[0019] like Figure 1 As shown, the bottom end of the top plate 3 is connected to the fixed plate 4 and the movable plate 5, wherein the fixed plate 4 is located at the front side and the movable plate 5 is located at the rear side of the fixed plate 4. The top plate 3 is connected to a second driving mechanism 6 for driving the movable plate 5 to move closer to or away from the fixed plate 4, that is, the movable plate 5 moves forward and backward; Figure 2As shown in the figure, a second guide groove 15 is provided on the top plate 3. The moving plate 5 is connected with a moving auxiliary plate 16 through a connecting portion 17. The moving auxiliary plate 16 is located on the upper end surface of the top plate 3. The connecting portion 17 is slidably connected in the second guide groove 15. The second driving mechanism 6 is connected with the moving auxiliary plate 16. In this embodiment, two connecting portions 17 are connected to the top end of the moving plate 5. Correspondingly, two second guide grooves 15 are provided on the top plate 3. The two connecting portions 17 are respectively slidably connected in the two second guide grooves 15. The second driving mechanism 6 is preferably a cylinder or an electric push rod.

[0020] As Figure 1 shown in the figure, a bag turning component 7 is connected to the bottom plate 2. When the bag turning component 7 moves upward, it can move between the fixed plate 4 and the moving plate 5, that is, the bag turning component 7 is located between the projections of the fixed plate 4 and the moving plate 5 on the bottom plate 2. The bag turning component 7 includes a corner supporting power plate 71, two upright columns 72 and two corner supporting blocks 73. The two upright columns 72 are vertically connected to the bottom plate 2, and the distribution direction of the two upright columns 72 is perpendicular to the moving direction of the moving plate 5, that is, the two upright columns 72 are distributed in the left-right direction. A corner supporting block 73 is rotatably connected to each upright column 72, and the rotation central axis of the corner supporting block 73 is arranged along the sliding direction of the moving plate 5. In this embodiment, the lower end of the corner supporting block 73 is rotatably connected to the upper end of the upright column 72. The front and rear end faces of the two corner supporting blocks 73 are flush. And in the initial state, the two opposite end faces of the two corner supporting blocks 73 are in contact with each other. The corner supporting power plate 71 is movably connected between the two upright columns 72. The two sides of the corner supporting power plate 71 are slidably connected to the two upright columns 72. The corner supporting power plate 71 moves up and down through a third driving mechanism (not shown in the figure). The third driving mechanism is preferably a cylinder or an electric push rod, and the third driving mechanism is connected to the upright column 72 or the bottom plate 2.

[0021] As Figure 1 shown in the figure, first inclined surfaces 8 that slope upward and inward toward the corner supporting power plate 71 are provided on both sides of the corner supporting power plate 71. The upper ends of the two first inclined surfaces 8 meet to form the top end of the corner supporting power plate 71, and the top end is located below the space between the two corner supporting blocks 73. It should be noted that the top end is not necessarily a sharp angle shape and can also be an arc shape. Second inclined surfaces 9 that slope upward and toward the direction of approaching another corner supporting block 73 are provided at the lower ends of the two corner supporting blocks 73.

[0022] When the corner supporting power plate 71 moves upward, the corner supporting power plate 71 abuts against the two corner supporting blocks 73 and causes the two corner supporting blocks 73 to rotate away from each other. A reset mechanism for causing the two corner supporting blocks 73 to close is connected to the two corner supporting blocks 73. As Figure 1 shown in the figure, the reset mechanism includes an elastic band 10. The elastic band 10 is connected to the upper ends of the two corner supporting blocks 73. When the corner supporting power plate 71 moves downward, the elastic band 10 causes the opposite end faces of the two corner supporting blocks 73 to be in contact with each other. As Figure 1As shown, a protruding rounded corner 11 is provided at the upper end of each corner support block 73 and at the corner far from the other corner support block 73; as Figure 2 As shown, air outlets 12 are provided on the two opposite end faces of the fixed plate 4 and the moving plate 5. The air outlets 12 are connected to a blower. The air outlets 12 are arranged obliquely downward towards the inner sides of the fixed plate 4 and the moving plate 5. Among them, the respective air outlets 12 on the fixed plate 4 and the moving plate 5 are respectively connected through a channel. Both channels are connected to an air pipe and are connected to the blower through the air pipe.

[0023] With the fixed plate 4 and the moving plate 5 as the bag - sleeving part, the canvas bag is sleeved on the fixed plate 4 and the moving plate 5 from bottom to top by a manipulator. Then, the moving plate 5 moves away from the fixed plate 4 to expand the canvas bag. At this time, the bottom plate 2 drives the bag - turning component 7 to move upward, and the two corner support blocks 73 rise and turn the canvas bag over. At this time, the turned - over canvas bag is sleeved on the two corner support blocks 73. Then, the corner support power plate 71 moves upward, causing the two corner support blocks 73 to rotate away from each other, thereby further propping up the bottom of the canvas bag to ensure that the canvas bag is turned over completely. Then, the blower blows air to blow off the items or documents remaining in the canvas bag, avoiding the remaining of items and documents. It not only has high efficiency, but also does not require manual operation during the turning - over process, reducing personnel participation, and is suitable for some special industries that require confidentiality.
