Compared with the traditional flipping which requires picking up and lifting, the flipping structure of this application simplifies the flipping steps, thereby improving the flipping efficiency. The setting of the first transmission component facilitates the automatic transmission of the sheet material to the gap between two adjacent flipping frames, thereby saving labor costs.

[0028] Currently, flipping components are widely used in product production lines. However, most flipping components use rotary cylinders and vacuum suction cups to pick up and lift products, and then perform a 180-degree flip. This requires a large space structure and the flipping process is cumbersome, which is not conducive to improving the efficiency of product production. The cost of equipment such as rotary cylinders and vacuum suction cups is high, which further increases the cost of product production and processing.

[0029] Based on this, this application proposes a flipping structure and system that can reduce the space required for flipping and simplify the flipping steps, thereby improving the production efficiency of the product.

[0030] It is understood that the flipping structure of this application includes a flipping assembly, a first driving assembly 160, a first transmission assembly, and a second transmission assembly. The flipping assembly includes a flipping shaft 100, on which at least two flipping frames 110 are provided. A gap 111 exists between two adjacent flipping frames 110, and the gap 111 is used to accommodate the sheet material to be flipped. The first driving assembly 160 is located on one side of the flipping shaft 100 and is used to drive the flipping shaft 100 to rotate in a first direction, so as to drive the flipping frames 110 to flip the sheet material contained in the gap 111 in the first direction. The first transmission assembly is located on one side of the flipping shaft 100 in the first direction and is used to transport the sheet material to the gap 111. The second transmission assembly is located on the side of the flipping shaft 100 away from the first transmission assembly in the first direction and is used to receive the sheet material after it has been flipped in the first direction.

[0031] The beneficial effects of the flipping structure in this application embodiment can be manifested as follows: by setting multiple flipping frames 110 on the flipping shaft 100, the sheet material can be placed in the gap 111 between two adjacent flipping frames 110. The setting of the first driving component 160 facilitates driving the flipping shaft 100 to rotate in the first direction, so as to drive the flipping frame 110 to perform a flipping operation on the sheet material. Compared with the traditional flipping which requires picking up and lifting, the flipping structure of this application simplifies the flipping steps and thus improves the flipping efficiency. The setting of the first transmission component facilitates the automatic transmission of the sheet material to the gap 111 between two adjacent flipping frames 110, thereby saving labor costs. The setting of the second transmission component facilitates the automatic disengagement of the sheet material from the gap 111 between two adjacent flipping frames 110 when the flipping frame 110 flips the sheet material onto the second transmission component, so that the sheet material can be transmitted to the next module through the second transmission component, thereby saving labor costs and improving efficiency.

[0032] For example, in some embodiments, reference is made to Figure 1 and Figure 3In this embodiment, the first drive assembly 160 is a combination of a servo motor and a reducer to provide stable speed and sufficient torque. The first drive assembly 160 is connected to the flipping shaft 100 via a first connecting rod, so that when the first drive assembly 160 is driven, it drives the flipping shaft 100 to rotate in the first direction via the first connecting rod. The flipping shaft 100 is provided with at least two flipping frames 110. The gap 111 between two adjacent flipping frames 110 is convenient for accommodating the sheet material to be flipped. The first transmission assembly is provided to facilitate the transport of the sheet material to the gap 111. The second transmission assembly is provided to facilitate the carrying of the sheet material that falls off from the gap 111 and to transport the sheet material to the next stage via the second transmission assembly. The specific flipping process is as follows: Initially, the gap 111 between two adjacent flipping frames 110 is at the same level as the sheet material transported by the first transmission assembly, so that when the first transmission assembly transports the sheet material to the flipping frame 110, the sheet material can slide into the gap 111 more easily. In step 1, when the sheet material slides into the gap 111, the first drive assembly 160 starts to drive the flipping shaft 100 to rotate in the first direction. Then, the flipping frame 110 drives the sheet material to rotate 180 degrees in the first direction until the sheet material at the gap 111 contacts the second transmission assembly. The second transmission assembly, which is transmitting in the first direction, drives the sheet material to gradually detach from the gap 111. At the same time, the flipping shaft 100 continues to rotate in the first direction, thereby prompting the sheet material to detach from the gap 111 onto the second transmission assembly more quickly. Then, the second transmission assembly transmits the sheet material to the next stage, while the flipping frame 110 continues to rotate in the first direction until it rotates back to its initial position, ready for the next sheet material flipping. This achieves a 180-degree flipping of the sheet material in a small space, saving space costs and simplifying the flipping steps. The sheet material can be flipped using only the gap 111 between the flipping frames 110 and the rotation of the flipping shaft 100, thereby improving the efficiency of sheet material flipping.

[0033] It is understood that: the first transmission component includes three sets of first transmission units, each of which includes a first conveyor belt and a first transmission frame 120. The first conveyor belt is fitted onto the first transmission frame 120. The three sets of first transmission units are arranged side by side along an axis parallel to the flip axis 100. The second transmission component includes three sets of second transmission units, each of which includes a second conveyor belt and a second transmission frame 140. The second conveyor belt is fitted onto the second transmission frame 140. The three sets of second transmission units are arranged side by side along an axis parallel to the flip axis 100. The three sets of first transmission units correspond one-to-one with the three sets of second transmission units.

[0034] For example, in some embodiments, reference is made to Figure 1 and Figure 2In this embodiment, two flipping shafts 100 are provided, arranged sequentially along the axial direction. This ensures that during flipping, the flipping frames 110 corresponding to both sets of flipping shafts 100 can support the sheet material, thereby further stabilizing the flipping process. The arrangement of three sets of first conveying units allows the sheet material to contact all three sets of first conveyor belts simultaneously when conveyed by the first conveying component. That is, the first conveyor belts of the three sets of first conveying units synchronously transport the sheet material. Compared to traditional conveying equipment, some conveying equipment only has one set of conveyor belts, resulting in insufficient support for the sheet material, which may lead to sheet material deviation and jamming. Two sets of conveyor belts can easily cause the sheet material to collapse in the middle. Therefore, the first conveying component of this application, by setting three sets of first conveyor belts to contact the sheet material, promotes... The first transmission component can transport the sheet material more stably, thereby improving the efficiency of sheet material flipping. Similarly, the arrangement of the three sets of first transmission units in the second transmission component facilitates the contact between the flipped sheet material and the three sets of second transmission belts. That is, the second transmission units of the three sets of second transmission units transport the sheet material synchronously to ensure the stable transmission of the sheet material by the second transmission component. The three sets of first transmission units correspond one-to-one with the three sets of second transmission units. That is, the three sets of first transmission units and the three sets of second transmission units are symmetrically arranged on opposite sides of the flipping axis 100 with the flipping axis 100 as the center of symmetry. Both ends of the first and second transmission belts are provided with limiting slots 124. The two ends of the limiting slots 124 are higher than the surface of the first or second transmission belt to prevent the first or second transmission belt from deviating in the horizontal direction.

[0035] It should be noted that all three sets of first transmission units are driven by the second drive component 130, and all three sets of second transmission units are driven by the third drive component 150.

[0036] Furthermore, in some other embodiments, a roller is also provided in the limiting slot 124. The outer wall of the roller contacts the first conveyor belt or the second conveyor belt, making the transmission of the first conveyor belt or the second conveyor belt smoother. At the same time, the roller and the limiting slot 124 are connected by a double bearing, making the connection between the two more firm and stable.

[0037] It is understood that the flipping structure of this application also includes a first baffle 170 and a second baffle 171. The first baffle 170 and the second baffle 171 are respectively disposed on both sides of the flipping shaft 100 along the axial direction of the flipping shaft 100. The first transmission component and the second transmission component are both disposed between the first baffle 170 and the second baffle 171.

[0038] For example, in some embodiments, reference is made to Figure 1In this embodiment, the first baffle 170 and the second baffle 171 are respectively disposed on opposite sides of the flipping shaft 100 along the axial direction of the flipping shaft 100. When the gap 111 between two adjacent flipping frames 110 accommodates the sheet material, the sheet material will also be located between the first baffle 170 and the second baffle 171, thereby limiting the sheet material and preventing it from detaching from the gap 111 along the axial direction of the flipping shaft 100. This further restricts and stabilizes the position and state of the sheet material during the flipping process, thereby improving the efficiency of sheet material flipping.

[0039] It is understandable that the flip shaft 100 is provided with eight flip frames 110, and the eight flip frames 110 and the flip shaft 100 form a disc structure, with a gap 111 between each adjacent flip frame 110.

[0040] For example, in some embodiments, reference is made to Figure 1 In this embodiment, there are eight flipping frames 110. The eight flipping frames 110 and the flipping shaft 100 form a disc structure. There is a gap 111 between two adjacent flipping frames 110. This allows the material to be loaded into the gap 111 of the first transmission component and unloaded into the gap 111 of the second transmission component at the same time during the flipping process. Along the first direction, there are three gaps 111 between the two gaps 111. Each of the three gaps 111 contains a set of sheet material, that is, three sets of sheet material are buffered for unloading. This causes the buffered sheet material to be unloaded at the same time as the flipping frame 110 performs the loading operation, thereby further improving the flipping efficiency.

[0041] It is understood that the first conveyor frame 120 is provided with a second drive assembly 130, a first transmission wheel 121 and a first tensioning shaft 122. The second drive assembly 130 is used to drive the first transmission wheel 121 to drive the first conveyor belt to rotate in the first direction. The first tensioning shaft 122 is used to press the first conveyor belt. The second conveyor assembly is also provided with a third drive assembly 150, a second transmission wheel 141 and a second tensioning shaft 142. The third drive assembly 150 is used to drive the second transmission wheel 141 to drive the second conveyor belt to rotate in the first direction. The second tensioning shaft 142 is used to press the second conveyor belt.

[0042] For example, in some embodiments, reference is made to Figure 1 and Figure 2In this embodiment, both the second drive assembly 130 and the third drive assembly 150 are speed reducers to increase the torque of the first and second conveyor belts, thereby improving the load tolerance of the first and second conveyor belts. The second drive assembly 130 is fixedly connected to the first transmission wheel 121 via a second connecting rod, facilitating the driving of the first transmission wheel 121 by the second drive assembly 130 to drive the first conveyor belt to move in the first direction. The third drive assembly 150 is fixedly connected to the second transmission wheel 141 via a third connecting rod, facilitating the driving of the second transmission wheel 141 by the third drive assembly 150 to drive the second conveyor belt to move in the first direction. The first tensioning wheel is used to press the first conveyor belt to adjust its tension and prevent it from over-tensioning. The first conveyor belt may slip due to excessive slack, meaning insufficient friction between it and the first drive wheel 121 could prevent the first drive wheel 121 from rotating, or it may be overly taut, increasing the load on the first drive wheel 121, thus reducing its lifespan and increasing maintenance costs. Similarly, the second tension wheel is used to tighten the second conveyor belt to adjust its tension, preventing slippage caused by excessive slack. This slippage occurs when the second conveyor belt is too loose, preventing insufficient friction between it and the second drive wheel 141, which could also prevent the second drive wheel 141 from rotating, or when it is overly taut, increasing the load on the second drive wheel 141, thus reducing its lifespan and increasing maintenance costs.

[0043] Furthermore, in other embodiments, the first drive wheel 121 is connected to the second connecting rod via a first knurled shaft and a first keyless expansion sleeve, so that by adjusting the first keyless expansion sleeve and the first knurled shaft, the position of the three sets of first conveying units on the second connecting rod can be adjusted, thereby achieving rapid adjustment of the overall width of the three sets of first conveyor belts in the first transmission assembly to adapt to different specifications of sheet materials. The second drive wheel 141 is connected to the third connecting rod via a second knurled shaft and a second keyless expansion sleeve, so that by adjusting the second keyless expansion sleeve and the second knurled shaft, the position of the three sets of second conveying units on the third connecting rod can be adjusted, thereby achieving rapid adjustment of the overall width of the three sets of second conveyor belts in the second transmission assembly to adapt to different specifications of sheet materials.

[0044] It should be noted that the second drive assembly 130 is connected to the second connecting rod via a double bearing and a bearing combination, and the third drive assembly 150 is connected to the third connecting rod via a double bearing and a bearing combination, making the connection more robust and stable.

[0045] It is understood that the first conveyor 120 is also equipped with a first sensor, and the second conveyor 140 is also equipped with a second sensor. When the first sensor senses the sheet material, it controls the first drive assembly 160 to drive the flipping shaft 100 to rotate in the first direction, so as to drive the flipping frame 110 to flip the sheet material on the first conveyor belt to the second conveyor belt. When the second sensor senses the sheet material, it controls the first drive assembly 160 to drive the flipping shaft 100 to rotate in the first direction, so as to drive the flipping frame 110 to detach the sheet material from the second conveyor belt.

[0046] For example, in some embodiments, reference is made to Figure 3 In this embodiment, both the first sensor and the second sensor are diffuse reflection sensors. The first sensor includes a first transmitter and a first receiver. The first receiver is mounted on the first conveyor frame 120 near the flip shaft 100 via a first mounting bracket 123 and is located below the first conveyor belt. The first transmitter is located above the first receiver so that the light emitted by the first transmitter can be received by the first receiver. The second sensor includes a second transmitter and a second receiver. The second receiver is mounted on the second conveyor frame 140 near the flip shaft 100 via a second mounting bracket 143 and is located below the second conveyor belt. The second transmitter is located above the second receiver so that the light emitted by the second transmitter can be received by the second receiver. In practical applications: When the sheet material is about to be transferred to gap 111 by the first transmission component, the sheet material blocks the first receiver, causing diffuse reflection of the light emitted by the first transmitter, which then scatters in all directions. At this time, the light emitted by the first transmitter is no longer completely received by the first receiver. The first receiver switches from having a sensing signal to having no sensing signal, thereby controlling the first drive component 160 to rotate, which in turn drives the flipping component to rotate in the first direction. At this time, the sheet material is just transferred to gap 111 by the first transmission component, and the sheet material is also driven to rotate in the first direction until the sheet material no longer blocks the first receiver. At this time, the sheet material is temporarily buffered at gap 111. A total of three sets of sheet materials can be buffered. When the sheet material is flipped 180 degrees to the second transmission component, the sheet material blocks the second receiver again. The second receiver switches from having a sensing signal to having no sensing signal, thereby controlling the first drive component 160 to rotate, which in turn drives the flipping component to rotate in the first direction, thus completely detaching the sheet material from gap 111 onto the second transmission component. This achieves full automation of loading and unloading, thereby saving labor costs and improving the flipping efficiency of the product.

[0047] It is understandable that the first baffle 170 and the second baffle 171 are both provided with a Teflon-plated layer on the side near the flip shaft 100.

[0048] For example, in some embodiments, reference is made to Figure 1In this embodiment, the side of the first baffle 170 and the second baffle 171 closest to the flipping shaft 100, that is, the side of the first baffle 170 and the second baffle 171 that contacts the sheet material, is coated with a layer of Teflon to prevent the sheet material from sticking to the first baffle 170 or the second baffle 171, thereby affecting the process and efficiency of sheet material flipping.

[0049] It is understood that the flipping structure of this application also includes a peeling component, which is connected to the end of the first transmission component away from the flipping axis 100. The peeling component is used to peel the sheet material onto the first transmission component.

[0050] For example, in some embodiments, reference is made to Figure 1 In this embodiment, the peeling assembly includes a fourth drive assembly 180, a pressure roller 181, a drive roller 182, and a peeling blade 183. One end of the bottom film carrying the sheet is located between the pressure roller 181 and the drive roller 182, and the other end is located at the peeling blade 183. The pressure roller 181 and the drive roller 182 are tightly abutted to prevent increasing the friction between the drive roller 182 and the bottom film. When peeling, the fourth drive assembly 180 drives the drive roller 182 to rotate in the opposite direction of the first direction, so as to drive the bottom film to start moving, thereby causing the bottom film at the peeling blade 183 to separate from the sheet, so that the sheet is peeled off from the bottom film and enters the first transmission assembly, thereby realizing automatic peeling and saving labor costs.

[0051] It is understandable that both the first and second conveyor belts are polyester canvas flat belts.

[0052] For example, in this embodiment, both the first conveyor belt and the second conveyor belt are made of polyester canvas flat belts in order to increase the friction between the sheet material and the first and second conveyor belts, thereby increasing the speed of sheet material conveying and avoiding sliding friction that would affect the conveying efficiency.

[0053] The system according to the second aspect of the application includes the flip structure of the first aspect of the application described above.

[0054] According to the system of this application embodiment, by setting multiple flipping frames 110 on the flipping shaft 100, the sheet material can be placed in the gap 111 between two adjacent flipping frames 110. The setting of the first driving component 160 facilitates the driving of the flipping shaft 100 to rotate in the first direction, so as to drive the flipping frames 110 to perform flipping operation on the sheet material. Compared with the traditional flipping which requires picking up and lifting, the flipping structure of this application simplifies the flipping steps, thereby improving the flipping efficiency. The setting of the first transmission component facilitates the automatic transmission of the sheet material to the gap 111 between two adjacent flipping frames 110, thereby saving labor costs. The setting of the second transmission component facilitates the automatic disengagement of the sheet material from the gap 111 between two adjacent flipping frames 110 when the flipping frame 110 flips the sheet material onto the second transmission component, so as to transfer the sheet material to the next module through the second transmission component, thereby saving labor costs and improving efficiency. By introducing the flipping structure of this application, the flipping process required by the system of this application is shorter, thereby improving the product flipping efficiency.

[0055] Since the system includes the flip structure of the first aspect embodiment, the corresponding contents of the flip structure in the first aspect embodiment can be applied to the system of the second aspect, and have the same implementation principle and technical effect. To avoid redundancy, they will not be described in detail here.

[0056] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
