Description

Technical Field

[0001] This utility model relates to the field of flipping machine technology, and in particular to an automatic flipping mechanism for a flipping machine. Background Technology

[0002] In the furniture manufacturing process, when processing boards, both ends of the boards need to be treated. Traditionally, if the other side needs to be processed after one side of the workpiece has been processed, the workpiece is flipped over manually, which is very labor-intensive for workers.

[0003] Chinese patent publication CN107416484A discloses a sheet metal flipping machine. This machine uses two parallel rods forming parallel forks to clamp the sheet metal within a cavity between the rods. This prevents relative movement of the sheet metal as it is flipped by multiple sets of parallel forks aligned on the same line, keeping it stable within the cavity and preventing it from detaching from the forks during flipping. It also prevents interference between the parallel forks and the sheet metal, facilitating continuous conveying. However, the size of the cavity for clamping the sheet metal is fixed, limiting its applicability to sheets of a fixed thickness. Utility Model Content

[0004] The present invention aims to solve, at least to some extent, one of the problems existing in the prior art. To this end, the present invention proposes an automatic flipping mechanism for a flipping machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic flipping mechanism for a flipping machine includes a double-speed chain conveyor for conveying boards and a flipping mechanism mounted on the double-speed chain conveyor for flipping the boards. The flipping mechanism includes a rotatably mounted flipping shaft and a power mechanism for driving the flipping shaft to rotate. A cross flipping assembly is mounted on the flipping shaft. The cross flipping assembly includes four mounting seats evenly distributed along the circumference of the outer wall of the flipping shaft. A flipping block is mounted on each mounting seat. The flipping block is provided with a flipping slot that allows the conveyed boards to enter. The opening size of the flipping slot is adjustable.

[0007] In some embodiments, a support plate is provided at the outer end of the mounting base, and a slide rail is provided on the outer side of the support plate. The flip block includes sliders that slide at intervals on the slide rail. A flip plate is provided on each of the two sliders, and a flip groove is formed between the two flip plates. A fixing bolt is also threadedly connected to the slider, and the threaded end of the fixing bolt can abut against the support plate.

[0008] In some embodiments, a scale line is also provided on one side of the support plate.

[0009] In some embodiments, an outwardly tilted guide plate is provided at the outer end of the flip plate.

[0012] In some embodiments, a flow strip for supporting and conveying the sheet metal is provided on the double-speed chain conveyor and between two sets of cross-turning assemblies.

[0013] In some embodiments, the power mechanism includes a first pulley disposed on the tilting shaft, a motor disposed on the double-speed chain conveyor, a second pulley disposed on the output shaft of the motor, and a belt sleeved between the first pulley and the second pulley.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When the board is flipped, it is conveyed by a double-speed chain conveyor and fed into the flipping slot of the flipping block. Then, the board is flipped 180° by the rotation of the flipping shaft. After flipping, the board continues to be conveyed on the double-speed chain conveyor to achieve continuous processing of the board.

[0016] 2. The opening size of the flipping slot used to accommodate the board is adjustable, so that the size of the flipping slot can be adjusted according to the thickness of the board. It is suitable for flipping most boards and is highly practical. Attached Figure Description

[0022] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0023] like Figures 1-5 An automatic flipping mechanism for a flipping machine is shown, comprising a double-speed chain conveyor 1 for conveying a plate 10 and a flipping mechanism disposed on the double-speed chain conveyor 1 for flipping the plate 10. The flipping mechanism includes a rotatable flipping shaft 2 and a power mechanism for driving the flipping shaft 2 to rotate. A cross flipping assembly 3 is disposed on the flipping shaft 2. The cross flipping assembly 3 includes four mounting seats 4 evenly distributed along the circumference of the outer wall of the flipping shaft 2. A flipping block 5 is disposed on each mounting seat 4. The four flipping blocks 5 are combined to form a cross-shaped structure. A flipping slot 6 is disposed on the flipping block 5 to allow the conveyed plate 10 to enter. The opening size of the flipping slot 6 is adjustable.

[0024] When the flipping machine of this utility model flips the board 10, the board 10 is conveyed by the double-speed chain conveyor 1 and conveyed into the flipping slot 6 of the flipping block 5. Then, by rotating the flipping shaft 2, the board 10 is flipped 180°. After the board is flipped, it continues to be conveyed on the double-speed chain conveyor 1 to realize the continuous processing of the board.

[0025] In addition, the opening size of the flip groove 6 used to accommodate the board 10 is adjustable, so that the size of the flip groove 6 can be adjusted according to the thickness of the board 10, which is suitable for flipping most boards and is highly practical.

[0026] See Figure 1 As shown, the power mechanism includes a first pulley 81 mounted on the tilting shaft 2, a motor 82 mounted on the double-speed chain conveyor 1, a second pulley 83 mounted on the output shaft of the motor 82, and a belt 84 connected between the first pulley 81 and the second pulley 83. Thus, the tilting shaft 2 is driven to rotate through the transmission of the first pulley 81, the second pulley 83, and the belt 84.

[0027] See Figure 1 , Figure 4 , Figure 5As shown, a support plate 21 is provided at the outer end of the mounting base 4, and a slide rail 22 is provided on the outer side of the support plate 21. The flipping block 5 includes sliders 23 that slide at intervals on the slide rail 22. A flipping plate 24 is provided on each of the two sliders 23, and a flipping slot 6 is formed between the two flipping plates 24. A fixing bolt 25 is also threadedly connected to the slider 23, and the threaded end of the fixing bolt 25 can be pressed against the support plate 21.

[0028] When adjusting the opening size of the flip slot 6, the slider 23 slides along the slide rail 22 to adjust the distance between the two flip plates 24, thereby adjusting the opening size of the flip slot 6. After the position is adjusted, the slider 23 is fixed by tightening the fixing bolt 25 so that the threaded end of the fixing bolt 25 presses against the support plate 21.

[0029] In order to clearly know the size of the opening of the flip slot 6, a scale line 31 is also provided on one side of the support plate 21.

[0030] In order to allow the plate 10 to smoothly enter the flipping slot 6, an outwardly tilted guide plate 41 is provided at the outer end of the flipping plate 24.

[0031] In order to protect the plate 10 and prevent it from being scratched, a soft rubber plate 51 is provided on the inner wall of the flip groove 6.

[0032] See Figure 1 , Figure 2 As shown, the cross-shaped flipping assembly 3 is provided in two sets at axial intervals along its flipping axis 2, thereby improving the stability of the plate during flipping.

[0033] Furthermore, a flow bar 71 for supporting and conveying the sheet material 10 is provided on the double-speed chain conveyor 1 and between the two sets of cross-turning components 3, thereby improving the stability of the sheet material when it is conveyed on the double-speed chain conveyor 1.
