Technical Field

[0001] The utility model relates to the field of turnover mechanisms, in particular to a turnover mechanism for a belt threading device. Background Art

[0002] The strapping device is mainly used for auxiliary packaging of pallet goods. The strapping device changes the extension angle of the chain through the flipping mechanism, so that the strapping belt passes through the bottom of the pallet goods and extends to the top of the goods, which is convenient for the staff to operate.

[0003] When the flip mechanism in the existing belt threading device is in use, the belt guide is reset by the upper drag chain, and when resetting, it touches the limit mechanism on one side, so that the limit mechanism is reset. However, the limit mechanism is prone to instability and usually needs to be reset manually. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a turning mechanism for a belt threading device to solve the technical problems mentioned in the above background technology.

[0005] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0006] By adopting the above technical solution, when the cargo pallet touches the movable plate or the seesaw when the flipping mechanism is moving, the triangular block on one side of the seesaw pushes the guide rod, and the pulley at one end of the guide rod disengages from the blocking block and slides along the limit plate to rotate the angle, so that the connecting sleeve is reset from 90 degrees to a horizontal state. When the belt guide slides on the connecting sleeve, the movable block and the spring elastic force on the belt guide are insufficient and fail to touch the guide rod in place, the connecting sleeve may also be reset to a horizontal state through any touch of the seesaw or the movable plate.

[0007] The present invention is further configured such that a first spring is provided on the other side of the seesaw, and the other end of the first spring is connected to the connecting sleeve.

[0008] By adopting the above technical solution, the first spring provided on the seesaw is connected to the connecting sleeve, so that the first spring can drive the seesaw to reset.

[0009] The utility model is further configured such that a guide plate is movably mounted on the end portion of the base plate.

[0010] By adopting the above technical solution, the bottom plate can be guided in a direction by the guide plate when it moves, thereby avoiding the problem of the bottom plate getting stuck due to uneven ground when it slides on the ground.

[0011] The utility model is further configured such that a limiting plate is fixed on one side of the top of the bottom plate, and a blocking block is fixed on the end of the limiting plate.

[0012] By adopting the above technical solution, the end of the guide rod can be limited by the provided limiting plate and the blocking block, thereby preventing the end of the guide rod from flipping over at an excessively large angle.

[0013] The utility model is further configured such that a pulley is movably mounted on one end of the guide rod.

[0014] By adopting the above technical solution, the friction between the guide rod and the limit plate and the blocking block can be reduced by the provided pulley.

[0015] The utility model is further configured such that a movable block is movably installed on one side of the top of the belt guide, and a mounting groove is provided on the top of the belt guide, a mounting rod is provided inside the mounting groove, a mounting hole is provided at the bottom of the movable block, and a second spring is fixed on one side of the movable block, and one end of the second spring is fixedly connected to the inner wall of the mounting groove.

[0016] By adopting the above technical solution, the movable block can squeeze the end of the guide rod when the belt guide is reset, causing the guide rod to rotate. The movable block also rotates on the inner wall of the installation groove, rotating around the installation rod as a circle, allowing the belt guide and the movable block to slide within the connecting sleeve.

[0017] The present invention is further configured such that a vertical groove is provided on one side of the belt guide, and an oblique groove is provided at the bottom end of the inner wall of the vertical groove.

[0018] By adopting the above technical solution, the vertical groove can facilitate the sliding of the end of the touch rod inside it. When the end of the touch rod contacts the inner wall of the inclined groove, it will squeeze the touch rod to move outward, thereby causing the end of the guide rod to rotate.

[0019] The utility model is further configured such that a clamping plate is provided at the end of the movable plate, and long holes are opened on both sides of the movable plate.

[0020] By adopting the above technical solution, the torsion spring can be limited by the provided clamping plate, so that one end of the torsion spring can give an elastic force to the end of the movable plate, and the long hole can be opened so that when the movable plate moves, the limiting column can move inside it.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The utility model is provided with a movable plate, a rocker plate, a connecting arm and a triangular block. When the movable plate or the rocker plate touches the pallet cargo during the movement of the flip mechanism, the triangular block at one end of the rocker plate drives the guide rod. The pulley at one end of the guide rod disengages from the blocking block and slides along the limit plate to rotate the angle, so that the connecting sleeve is reset to a horizontal state from 90 degrees. When the belt guide slides on the connecting sleeve, if the elastic force of the movable block and the spring on the belt guide are insufficient and the guide rod is not in place, the connecting sleeve may be reset to a horizontal state by any contact of the rocker plate or the movable plate.

Pins 52 are provided on both sides of the limit block 51, and the pins 52 are movably connected to the connecting sleeve 6. A triangular block 4 is fixed to one side of the rocker 5. At this time, the rocker 5 will contact the bottom of the cargo pallet. According to the principle of leverage, the rocker 5 rotates with the pin 52 as the center of the circle, and the triangular block 54 on one side of the rocker 5 pushes the guide rod 8. At the same time, the first spring 53 on the other side of the rocker 5 is compressed. According to the principle of leverage, the pulley at the end of the guide rod 8 will move away from the blocking block 12. When the connecting sleeve 6 is reset to a horizontal state, the guide rod 8 is separated from the triangular block 54 on one side of the rocker, and the first spring 53 pulls the rocker 5 to reset. The inner sleeve of the connecting sleeve 6 is provided with a guide 7. The connecting sleeve 6, the connecting arm 31, the guide rod 8 and the limit sleeve 3 constitute a flip assembly.

[0031] See also Figure 3 A first spring 53 is provided on the other side of the seesaw 5, and the other end of the first spring 53 is connected to the connecting sleeve 6. The seesaw 5 is connected to the connecting sleeve 6 through the provided first spring 53, so that the first spring 53 can drive the seesaw 5 to reset.

[0032] See also Figure 2 A guide plate 2 is movably installed at the end of the base plate 1. When the base plate 1 moves, the guide plate 2 can guide the direction, thereby avoiding the problem of jamming caused by uneven ground when the base plate 1 slides on the ground.

[0033] See also Figure 2 A limiting plate 11 is fixed on one side of the top of the base plate 1, and a blocking block 12 is fixed at the end of the limiting plate 11. The limiting plate 11 and the blocking block 12 can limit the end of the guide rod 8 to prevent the end of the guide rod 8 from flipping at too large an angle.

[0034] See also Figure 2 A pulley 81 is movably mounted on one end of the guide rod 8 , and the pulley 81 can reduce the friction between the guide rod 8 and the limiting plate 11 and the blocking block 12 .

[0035] See also Figure 4 The movable block 71 is movably installed on one side of the top of the belt guide 7, and a mounting groove 73 is provided on the top of the belt guide 7, and a mounting rod 77 is provided inside the mounting groove 73. A mounting hole 76 is provided at the bottom of the movable block 71, and a second spring 72 is fixed to one side of the movable block 71, and one end of the second spring 72 is fixedly connected to the inner wall of the mounting groove 73. The movable block 71 can squeeze the end of the guide rod 8 when the belt guide 7 is reset, and the movable block 71 will rotate on the inner wall of the mounting groove 73. The movable block 71 rotates with the mounting rod 77 as the center, so that the belt guide 7 and the movable block 71 can slide inside the connecting sleeve 6.

[0036] See also Figure 4 A vertical groove 74 is provided on one side of the guide member 7, and an inclined groove 75 is provided at the bottom end of the inner wall of the vertical groove 74. The vertical groove 74 can facilitate the sliding of the end of the touch rod 82 inside it. When the end of the touch rod 82 contacts the inner wall of the inclined groove 75, it will squeeze the touch rod 82 to move outward, thereby causing the end pulley 81 of the guide rod 8 to rotate along the limit plate 11.

[0037] See also Figure 1 and Figure 2 A clamping plate 42 is provided at the end of the movable plate 4, and long holes 41 are opened on both sides of the movable plate 4. The clamping plate 42 can limit the torsion spring 32, so that one end of the torsion spring 32 can give an elastic force to the end of the movable plate 4. The long hole 41 can make the limit column 33 move inside the movable plate 4 when the movable plate 4 moves.

[0038] When the belt guide 7 is in operation, the lower drag chain drives the bottom plate 1 to move. When it reaches the specified position, the upper drag chain drives the belt guide 7 to move. When the belt guide 7 moves, the belt guide 7 slides inside the connecting sleeve 6. When the belt guide 7 moves, it drives the connecting sleeve 6 to flip. When the connecting sleeve 6 flips, the connecting arm 31 on one side will also change its angle. When the connecting sleeve 6 rotates to 90 degrees, the belt guide 7 will continue to move. When the belt guide 7 continues to move, the contact rod 82 will slide in the vertical groove 74 on one side of the belt guide 7. When the contact rod 82 contacts the inner wall of the inclined groove 75, the contact rod 82 is squeezed to one side under the action of the inclined groove 75. According to the lever principle, the end of the guide rod 8 will rotate to one side, and the pulley 81 at the end of the guide rod 8 will stop rotating under the limiting action of the blocking block 12, and then the belt guide 7 will continue to move.

[0039] When the guide rod 8 drives the connecting sleeve 6 to return to the horizontal state, the first spring 53 drives the rocker 51 to return to the original state.

[0040] Or when the cargo pallet collides with the movable plate 4, the end of the movable plate 4 moves downward to push the rocker. At this time, the clamping plate 42 squeezes the torsion spring 32, and the end of the movable plate 4 squeezes the rocker 5, so that the triangular block 54 on one side of the rocker 5 pushes the guide rod 8. According to the principle of leverage, the pulley at the end of the guide rod 8 will move away from the blocking block 12, so that the guide rod 8 drives the connecting sleeve 6 to return to a horizontal state.
