DETAILED DESCRIPTION

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] A bag body steering device for paper bag packaging equipment includes a turntable 2, a rotating pressure block 3 and a pushing mechanism. The turntable 2 is transmission-connected with a rotating driving component, and the rotating driving component is arranged on a frame. The discharge end of the bag making machine is connected with the feed end of the turntable 2. The paper bag making machine sends the bag body to the turntable 2 through a conveying device. The turntable 2 can rotate unidirectionally or bidirectionally. When the bag mouth of the bag body faces left or right, the turntable 2 only needs to rotate unidirectionally intermittently, that is, the first bag body is pushed out by the push plate 41 without rotating, and the second bag body is rotated and then pushed out by the push plate 41. When the bag mouth of the bag body faces forward or backward, the turntable 2 rotates bidirectionally. The turntable 2 rotates forward or reversely to make the bottom of the bag body alternately face left or right. The bags can be turned one by one or in small batches. In order to improve efficiency, batch delivery is usually adopted. The rotating pressing block 3 is connected to the first lifting driving component that drives the rotating pressing block 3 to move up and down. The rotating pressing block 3 is arranged above the turntable 2. The rotating pressing block 3 cooperates with the turntable 2 to turn the bag mouth of the bag body. The rotating pressing block 3 descends and presses the bag body on the turntable 2. The two rotate and cooperate to turn the bag body to prevent the bag body from floating during the bag body turning process. Specifically, the first lifting driving component drives the rotating pressing block 3 to descend and press the bag body. The rotating driving component drives the turntable 2 to drive the bag body to rotate forward or reversely, so that the bag body is placed horizontally, and the bag mouth of the bag body after rotation is opposite to the bag mouth of the previous batch of rotating bags. The push plate 41 is connected to the driving component that drives the push plate 41 to move, and the driving component can drive the push plate 41 to push the bag body.

[0020] Among them, Figure 1 and Figure 2 As shown, the turntable 2 is arranged on the rotating station 11 of the material receiving and conveying platform 1, and the material receiving and conveying platform 1 has a through hole for the turntable 2 to pass through, as shown in FIG. Figure 2As shown, the through hole is for installing the turntable 2; a bag pressing station 12 and a discharging station 13 are further provided in front of the rotating station 11. The turntable 2 is arranged on the rotating station 11, and when the turntable 2 works, the working plane is not lower than the material receiving plane of the material receiving conveying platform 1. At the bag pressing station 12, there is a liftable bag pressing plate 6. The bag pressing plate 6 is arranged above the material receiving conveying platform 1. There is a telescopic air cylinder on the frame, and the driving rod of the telescopic air cylinder is connected to the bag pressing plate 6. The bag pressing plate 6 is arranged between the push plates 41 on both sides to press down the bag body pushed to the bag pressing station 12, reducing the volume of a small batch of bag bodies, and the bag pressing plate 6 flattens the bag body. Flattening helps to ensure that the bonding part of the bag body receives sufficient and uniform pressure, enabling the glue or adhesive to better combine with the paper fibers and improving the firmness of bonding. Push plates 41 are arranged at the rotating station 11, the bag pressing station 12, and the discharging station 13. To avoid interference between the push plates 41 and the bag bodies during the return process, the push plates 41 are respectively arranged on both sides of the turntable 2. The driving assembly includes an avoidance driving component and a material pushing driving component. The avoidance driving component drives the push plate 41 to avoid the bag body, and the material pushing driving component drives the push plate 41 to push the bag body. The push plate 41 has an avoidance state and a material pushing state. In the avoidance state, the push plate 41 can avoid the bag body; in the material pushing state, the push plate 41 can push the bag body. The first push plate 41 at the rotating station 11 returns after pushing the rotated bag body into the bag pressing station 12. The second push plate 41 at the bag pressing station 12 returns after pushing the flattened bag body into the discharging station 13. The third push plate 41 at the discharging station 13 returns after pushing the bag body into the next process. Multiple groups of push plates 41 cooperate to feed the material simultaneously, improving the working efficiency.

[0021] There are many ways for the push plate 41 to avoid the bag body. For example, the push plates 41 on both sides rise to avoid. The push plates 41 of each specific station are arranged on the first avoidance moving plate. The push plates 41 are arranged above the material conveying platform 1. The push plates 41 are arranged on both sides of the rotating pressing block 3. The first avoidance moving plate is connected to the avoidance driving component that drives it to move up and down. The avoidance driving component is a lifting driving component. The avoidance driving component is arranged on the first material pushing mounting seat. The first material pushing mounting seat is connected to the pushing driving component. The avoidance driving component is fixedly arranged on the first material pushing mounting seat, and the driving rod of the avoidance driving component is connected to the first avoidance moving plate. The push plates 41 of each station descend to enter the material pushing state. The material pushing driving component drives the push plate 41 on the first material pushing mounting seat to push the bag body. The avoidance driving component drives the push plate 41 to rise so that the push plate 41 enters the avoidance state to avoid interference. Alternatively, the push plates 41 on both sides are relatively far away from each other for avoidance. Specifically, the two sides of the material conveying platform 1 are provided with second pusher mounting seats 51, which are transmission-connected with the pusher driving component, and there are guide rods 54 between the second pusher mounting seats 51. The push plate 41 is arranged on the second avoidance movable plate 52, and the second avoidance movable plate 52 is slidably arranged on the guide rods 54. The avoidance driving component is a transverse driving component, and the avoidance driving component is transmission-connected with the second avoidance movable plate 52. The avoidance driving component is fixedly arranged below the material conveying platform 1, and the driving rod of the avoidance driving component is connected with the second avoidance movable plate 52, and the second avoidance movable plate 52 is slidably arranged on the guide rods 54. The second avoidance driving plate drives the push plate 41 to move left and right, and the second pusher mounting seats 51 move at the same time, driving the push plates 41 on both sides to push the bag body. The power source of the avoidance driving component can be a motor or a cylinder, and the pusher driving component can be a screw drive or a conveyor belt drive or a cylinder, etc.

[0022] On the basis that the push plate 41 can move laterally, the push plate 41 and the side baffle 42 are vertically arranged, the push plate 41 contacts the rear side of the bag body, and the side baffle 42 contacts the side of the bag body. The side baffle 42 is arranged on the outside of the push plate 41. When the push plates 41 are close to each other, the side baffles 42 on both sides organize the bag bodies to ensure that the bags are neatly stacked during transportation. Specifically, the push plate 41 and the side baffle 42 are integrally formed. For example, the push plate 41 is an L-shaped plate, and the side baffle 42 can also be fixedly arranged on the push plate 41. Example 1

[0023] The conveying device of the paper bag making machine feeds the longitudinally placed bag bodies onto the turntable 2. The rotating pressing block 3 descends to press the bag bodies. The turntable 2 and the rotating pressing block 3 cooperate to rotate the bag bodies forward by 90°, making the bag openings face left. The push plates 41 at the rotating station 11 move closer to each other, and the side baffles 42 regularize the two sides of the bag bodies. The push plates 41 and the side baffles 42 push the bag bodies to the bag pressing station 12. During the pushing process, the side baffles 42 ensure that the bag bodies are stacked neatly. After reaching the position, the bag pressing plate 6 descends to press the bag bodies and flatten them. The push plates 41 move away from each other left and right and return to the rotating station 11. The push plates 41 at the bag pressing station 12 return from the discharging station 13. When the bag bodies at the bag pressing station 12 are sent to the discharging station 13, the side baffles 42 at the bag pressing station 12 regularize the bag bodies again. Subsequently, the push plates 41 send the flattened bag bodies into the discharging station 13. After the compacted bag bodies are sent out, the push plates 41 at the rotating station 11 send the bag bodies after reverse rotation (i.e., the bag bodies with the bag openings facing right) into the bag pressing station 12. The forward and reverse bag bodies are sent out in sequence at the rotating station 11, ensuring that the subsequent stack of bag bodies is flat and laying a foundation for subsequent packing of the bag bodies. Embodiment 2

[0024] The paper bag making machine feeds the longitudinally arranged bag bodies onto the turntable 2. The rotating pressing block 3 descends to press the bag bodies. The turntable 2 and the rotating pressing block 3 cooperate to rotate the bag bodies forward by 90°, making the bag openings face left. The push plates 41 descend and move to the rear of the bag bodies. The pushing driving component drives the push plates 41 to push the bag bodies to the bag pressing station 12. The bag pressing plate 6 descends to press the bag bodies and flatten them. The push plates 41 rise and return. The push plates 41 at the bag pressing station 12 descend together and move to the rear of the compacted bag bodies. The push plates 41 at the bag pressing station 12 send the compacted bag bodies to the discharging station 13. At the same time, the push plates 41 at the rotating station 11 send the bag bodies after reverse rotation by 90° (i.e., the bag bodies with the bag openings facing right) into the bag pressing station 12. Such repeated conveying sends the forward and reverse bag bodies out in sequence, ensuring that the subsequent stacked bag bodies are flat and laying a foundation for subsequent packing of the stacked bag bodies.
