[0025] Refer to Figures 1 to 6 As shown, a high-speed turning bag mechanism in an embodiment provided by the present invention includes a frame component, a transmission component and a turning bag component. The transmission component and the turning bag component are both arranged on the frame component; the turning bag component includes a central shaft 3-2, turning bag wheels and a plurality of turning bag plate assemblies. The two ends of the central shaft 3-2 are respectively connected to the frame component. The turning bag wheels are sleeved on the central shaft 3-2. A cam 3-11 is sleeved on the central shaft 3-2. The plurality of turning bag plate assemblies are arranged circumferentially along the cam 3-11. The turning bag plate assemblies are hinged to the turning bag wheels through connecting shafts 3-8. The inner sides of the turning bag plate assemblies are in contact with the edges of the cam 3-11; the transmission component is connected to the turning bag wheels to drive the turning bag wheels to rotate around the central shaft 3-2. During the rotation of the turning bag plate assemblies with the turning bag wheels, the inner sides of the turning bag plate assemblies continuously contact the edges of the cam 3-11. The turning bag plate assemblies contact different positions of the edges of the cam 3-11 to form a certain angle of flipping.

[0026] Further, the turning bag wheels are connected to the central shaft 3-2 through bearings. The central shaft 3-2 is fixedly connected to the frame component through fixing blocks, or the turning bag wheels are fixedly connected to the central shaft, and the central shaft is connected to the frame component through bearings.

[0027] Further, the number of the turning bag plate assemblies is 4 to 8, and the optimal number of the turning bag plate assemblies is 6.

[0028] Further, the turning bag plate assembly includes a turning bag plate 3-9, a pushing plate 3-6, a spring 3-10 and a rotating shaft seat 3-12.

The two ends of the spring 3-10 are respectively connected to the rotating shaft seat 3-12 and the pushing plate 3-6.

[0029] Further, the spring 3-10 is sleeved on the turning shaft 3-13.

[0030] Further, a receiving groove is provided on the outer side of the turnover plate 3-9, and the turnover plate 3-9 is L-shaped; the L-shaped groove faces outward, and the L-shaped groove is used to receive and hold materials. The long side of the L-shaped turnover plate 3-9 is the bag receiving surface 3-14, and the ear seat 3-15 is arranged on the short side of the L-shaped turnover plate 3-9.

The protrusions 3-17 are arranged corresponding to the jacks 3-16. When the turnover plate 3-9 rotates to the long axis of the cam 3-11, the cam 3-11 pushes the corresponding push plate 3-6 of the turnover plate 3-9 outwards. The protrusions 3-17 on the push plate 3-6 pass through the jacks 3-16 of the turnover plate 3-9, and the materials in the turnover plate 3-9 are pushed out, so as to unload the materials onto the docking conveying equipment. When the turnover plate 3-9 rotates to the short axis of the cam 3-11, the push plate 3-6 of the turnover plate 3-9 retracts, so that the protrusions 3-17 on the push plate 3-6 withdraw from the jacks 3-16 of the turnover plate 3-9, facilitating the upstream conveying equipment to convey the materials onto the turnover plate 3-9.

[0032] Further, rollers 3-18 are provided on the push plate 3-6, and the push plate 3-6 is in contact connection with the cam 3-11 through the rollers 3-18.

[0033] Further, the roller 3-18 can be a rotating wheel or a semi-circular fixed wheel.

[0034] Further, the long axis of the cam 3-11 is arranged horizontally or obliquely downward; so as to facilitate the smooth unloading of materials and fall onto the docking conveying equipment.

[0035] Further, the number of turnover wheels is 2, namely a left turnover wheel and a right turnover wheel. The 2 turnover wheels are sequentially arranged on the central shaft 3-2, and are respectively arranged on both sides of the turnover plate assembly and the cam 3-11.

[0036] Further, the transmission component includes a synchronous belt 2-2, two synchronous belt pulleys 3-1 and a motor reducer 2-1. The two synchronous belt pulleys 3-1 are connected by the synchronous belt 2-2. One synchronous belt pulley 3-1 is connected to the turnover wheel, and the other synchronous belt pulley 3-1 is connected to the motor reducer 2-1.

[0037] Further, the synchronous belt 2-2 and the synchronous belt pulley 3-1 are replaced by a chain and a sprocket, or replaced by a belt and a pulley.

[0038] Further, the frame member includes a left side plate 1-1, a right side plate 1-5, and a left and right side plate connecting plate 1-4. The left side plate 1-1 and the right side plate 1-5 are arranged in parallel. Both ends of the central shaft 3-2 are connected to the left side plate 1-1 and the right side plate 1-5 respectively. Both ends of the left and right side plate connecting plate 1-4 are connected to the left side plate 1-1 and the right side plate 1-5 respectively. The motor reducer 2-1 is fixedly connected to the left and right side plate connecting plate 1-4 through the motor reducer mounting plate 1-3.

[0039] In one embodiment of the present invention, a high-speed bag turning mechanism includes a frame member, a transmission member, and a bag turning member. The transmission member includes a motor reducer 2-1, a synchronous belt 2-2, and a synchronous pulley 3-1. The bag turning member includes a left bag turning wheel 3-4, a right bag turning wheel 3-7, a central shaft 3-2, bearings, a bag turning plate 3-9, a connecting shaft 3-8, and bag turning plate fixing screws 3-5. Both the motor reducer 2-1 and the central shaft 3-2 are respectively fixed on the frame member. The motor reducer 2-1 drives the rotation of the bag turning member through the synchronous belt 2-2.

[0040] The bag turning method of the present invention is as follows: The soft bag materials conveyed from the front end fall onto the bag turning plate. As the bag turning plate rotates, the materials are flipped 180° and fall onto the subsequent conveying equipment, realizing the function of flipping the materials by 180 degrees. Due to the intermittent bag turning technology of driving the bag turning member by the motor reducer, the bag turning speed of the materials is significantly improved, and the production efficiency of the entire production line is increased.

[0041] Further, the central shaft 3-2 passes through the left bag turning wheel 3-4 and the right bag turning wheel 3-7. The left bag turning wheel 3-4 and the right bag turning wheel 3-7 are mirror-structured and are installed on both sides of the central shaft 3-2 and are connected to the central shaft 3-2 through bearings. The inner ring of the bearing is in interference fit with the central shaft 3-2, and the outer ring is in transitional fit with the central inner hole of the left bag turning wheel 3-4 and the right bag turning wheel 3-7, so that the left bag turning wheel 3-4 and the right bag turning wheel 3-7 can rotate around the central shaft 3-2. A synchronous pulley 3-1 is fixed on the outer side of the left bag turning wheel 3-4.

[0042] Further, six bag turning plates 3-9 with the same structure are arranged at 60 degrees to each other between the left bag turning wheel 3-4 and the right bag turning wheel 3-7. Each bag turning plate 3-9 is designed with two ear seats 3-15. The connecting shaft 3-8 passes through these two ear seats 3-15 and is connected to the left bag turning wheel 3-4 and the right bag turning wheel 3-7. The bag turning plate 3-9 and the connecting shaft 3-8 are both fixed on the left bag turning wheel 3-4 and the right bag turning wheel 3-7 through screws, so that the bag turning plate 3-9, the connecting shaft 3-8, the left bag turning wheel 3-4, and the right bag turning wheel 3-7 form an integral body.

[0043] Further, as can be seen from the cross-section perpendicular to the central axis 3-2, the turning-over plate 3-9 forms a certain angle with the plane formed by the central axis 3-2 and the connecting shaft 3-8. This angle can ensure smooth bag receiving and discharging, and can be adjusted according to different materials.

[0044] Further, the central axis installed with the left turning-over wheel 3-4, the right turning-over wheel 3-7, bearings, the turning-over plate 3-9, and the connecting shaft 3-8 is installed on the left side plate 1-1 and the right side plate 1-5 of the frame component. The central axis 3-2 is fixed on the side plates through the fixing blocks 3-3 fixed on the side plates, so that the central axis 3-2 cannot rotate, while the turning-over component can rotate around the central axis 3-2 through the bearings.

[0045] Further, the motor speed reducer 2-1 is fixed on the frame component. A synchronous pulley is installed at the output shaft end of the motor speed reducer 2-1 and is connected to the synchronous pulley 3-1 fixed outside the left turning-over wheel 3-4 through the synchronous belt 2-2. When the motor speed reducer 2-1 rotates, it drives the turning-over component to rotate.

[0046] Further, the frame component includes a left side plate 1-1, a right side plate 1-5, a motor speed reducer mounting plate 1-3, a left and right side plate connecting plate 1-4, and a sealing plate 1-2. The motor speed reducer 2-1 is fixed on the motor speed reducer mounting plate 1-3. The motor speed reducer mounting plate 1-3 is installed between the two left and right side plate connecting plates, so that the left side plate 1-1, the right side plate 1-5, the motor speed reducer mounting plate 1-3, and the left and right side plate connecting plates 1-4 form a stable overall structure. The sealing plate 1-2 is fixed on the opening of the left and right side plates.

[0047] The working principle of the present invention: The soft bag materials conveyed from the front fall onto the turning-over plate. As the turning-over plate rotates, the materials are turned over by 180° and fall onto the subsequent conveying equipment, realizing the function of turning over the materials by 180 degrees. Due to the intermittent turning-over technology of driving the turning-over component by the motor speed reducer, the turning-over speed of the materials is significantly improved, and the production efficiency of the entire production line is improved.

[0048] The above are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited by this. Therefore, the equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
