Description

Technical Field

[0001] This invention relates to the field of smart sofa manufacturing technology, and in particular to a flipping device for smart sofa manufacturing. Background Technology

[0002] Smart sofas are a new type of sofa that integrates technology with the functions of traditional furniture. In the manufacturing process of smart sofas, especially for those with wooden frames, the sofa frame often needs to be flipped to facilitate processing, assembly, and inspection of the bottom, sides, backrest, and other aspects. Currently, the flipping of the sofa frame in the existing production process relies on a simple mechanical structure. Therefore, the flipping axis of the existing sofa frame is usually relatively fixed and cannot meet the flexible needs of multi-directional and multi-angle flipping in the production of sofa frames. This results in the need for manual adjustment after the sofa frame is mechanically flipped, which leads to poor operational convenience in the production process of sofa frames. Summary of the Invention

[0003] In order to overcome the shortcomings mentioned in the background art, the present invention provides a flipping device for intelligent sofa production.

[0004] The technical solution is as follows: A flipping device for intelligent sofa production includes a worktable, a rotating frame rotatably connected to the worktable, a motor mounted on the worktable, and a gear transmission between the output shaft of the motor and the rotating frame. Two symmetrically distributed first electric push rods are mounted on the worktable, and sliding pins are fixedly connected to the telescopic portions of the first electric push rods. Two symmetrically distributed top frames are slidably connected to the rotating frame, and each top frame has a sliding groove. The sliding pins slide within adjacent sliding grooves. Support blocks are rotatably connected to each top frame, and torsion springs are fixedly connected between the support blocks and adjacent top frames. The two support blocks are respectively used to push the sofa frame base and backrest to flip the sofa frame. The rotating frame drives the two top frames to rotate, thereby adjusting the rotation axis of the sofa frame during flipping, allowing the sofa frame to flip in multiple directions.

[0005] Preferably, the sliding groove is semi-circular, and the axis of the circle containing the sliding groove is collinear with the rotation axis of the rotating frame.

[0006] Preferably, the rotating frame is rotatably connected to a support frame, the support frame having a V-shaped surface, and the support frame is used to limit the position of the sofa frame.

[0007] Preferably, the axis of the support frame is perpendicular to the rotation axis of the rotating frame.

[0008] Preferably, the support frame is fixedly connected to two symmetrically distributed second electric push rods, the telescopic parts of the second electric push rods are detachably connected to connecting plates, and limit blocks are fixedly connected to opposite sides of the two connecting plates.

[0009] Preferably, the axis of the limiting block is misaligned with that of the second electric push rod, so that the limiting block is misaligned with the backrest of the sofa frame.

[0010] Preferably, the thickness of the limiting block gradually increases from near the axis of the rotating frame to far away from it.

[0011] Preferably, the limiting block is fixedly connected to a flexible block, the flexible block being used to fit the sofa frame, and a flexible part is provided above the top frame, the flexible part being used to fit the sofa frame.

[0012] Preferably, the upper side of the flexible part is lower than the upper side of the rotating frame.

[0013] Preferably, the support frame is slidably connected to a sliding plate, the sliding plate is fixedly connected to a flexible pad, and the flexible pad is provided with a plurality of protrusions.

[0014] The beneficial effects of this invention are as follows: This invention flips the sofa frame by pushing it with two support blocks, and by changing the position of the support blocks, the rotation axis of the sofa frame during flipping is adjusted, allowing the sofa frame to flip in multiple directions. This increases the flippable shape of the sofa frame and improves the ease of operation during the sofa frame production process. Before flipping the sofa frame, two limiting blocks are used to fix different models of sofa frames to reduce the probability of displacement or even injury to operators during the subsequent flipping process, thereby improving the safety of the sofa frame flipping process. Furthermore, during the flipping process, the automatic rotation of the support blocks ensures that the flexible part of the support blocks always fits the sofa frame, increasing the stress area of ​​the sofa frame and dispersing the stress points on the surface of the sofa frame, thereby reducing the probability of the sofa frame being crushed. When the sofa frame moves horizontally, the sofa frame drives the flexible pad and sliding plate to move horizontally through the protrusions, reducing the probability of relative displacement between the sofa frame and the supported points, thereby reducing the probability of wear caused by movement during the production process and improving the quality of the sofa frame after production.

Detailed Implementation

[0024] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0025] Example 1

[0026] Currently, most sofa frames are flipped using simple, general-purpose flipping machines. However, the flipping axis of these machines is usually fixed and cannot meet the flexible requirements of multi-directional and multi-angle flipping in sofa frame production. After the sofa frame is flipped, its position needs to be manually fine-tuned. This not only makes the operation in the sofa frame production process inconvenient, but also poses a risk of hand injury from the wooden sofa frame when manually adjusting its position. Therefore, the convenience and safety of existing sofa frame flipping devices are poor.

[0027] A flipping device for producing smart sofas, such as Figures 1-5As shown, the system includes a worktable 1 with several spaced-apart rotating rollers for conveying the sofa frame. A control terminal (not shown) is mounted on the worktable 1. A rotating frame 2 is rotatably connected to the worktable 1, supporting the sofa frame. A motor 3, electrically connected to the control terminal, is mounted on the worktable 1. The output shaft of the motor 3 is driven by a gear set to the rotating frame 2, consisting of two spur gears. The output shaft of the motor 3 is fixedly connected to one spur gear, and the rotating frame 2 is fixedly connected to the other spur gear. Two first electric push rods 4 are symmetrically distributed front and rear on the worktable 1. The push rod 4 is electrically connected to the control terminal. A sliding pin 5 is fixedly connected to the telescopic part of the first electric push rod 4. The telescopic part of the first electric push rod 4 is used to drive the sliding pin 5 to move. The rotating frame 2 is slidably connected to two symmetrically distributed top frames 6. Each top frame 6 is provided with a sliding groove 601. The sliding pin 5 slides within adjacent sliding grooves 601. A support block 7 is rotatably connected to each top frame 6. A torsion spring 701 is fixedly connected between the support block 7 and the adjacent top frame 6. As the support block 7 moves upward, pushing the sofa frame to move, the support block 7 gradually rotates, and the torsion spring 701 gradually twists and stores force to increase the contact area between the flexible part 13 and the sofa frame, dispersing... The sofa frame surface has stress points to reduce the probability of the sofa frame being crushed. When the support block 7 moves downward and resets, the torsion spring 701 resets and drives the support block 7 to rotate and reset. The two support blocks 7 are used to push the sofa frame base and backrest respectively to flip the sofa frame, thereby improving the convenience of the sofa frame flipping process during production. The rotating frame 2 drives the two top frames 6 to rotate, thereby adjusting the rotation axis of the sofa frame during flipping. Using mechanical flipping, while protecting the operator, the sofa frame can be flipped in multiple directions, thereby improving the convenience of the sofa frame flipping process. The sliding groove 601 is a semi-circular ring, sliding... The axis of the circle containing groove 601 is collinear with the rotation axis of the rotating frame 2. During the rotation of the two top frames 6 driven by the rotating frame 2, the sliding pin 5 moves within the adjacent sliding groove 601, and the maximum sliding angle of the sliding pin 5 is less than 180° to prevent the sliding pin 5 from sliding out of the adjacent sliding groove 601. When the rotating frame 2 drives the sofa frame to rotate, the telescopic part of the first electric push rod 4 can still drive the top frame 6 to move upward through the sliding pin 5. The support block 7 drives the sofa frame to flip, thereby changing the position of the sofa frame flip axis, thus increasing the flippable shape of the sofa frame and improving the ease of operation in the sofa frame production process.

[0028] like Figure 4 , Figure 6 and Figure 7As shown, the rotating frame 2 is rotatably connected to the support frame 8. The support frame 8 is provided with a V-shaped surface. During the processing of the sofa frame, the support frame 8 limits the sofa frame to reduce the probability of displacement of the sofa frame, thereby reducing the probability of the operator's hand being cut due to the position of the sofa frame, and thus improving the safety of the device. The axis of the support frame 8 is perpendicular to the rotation axis of the rotating frame 2 so that the axis of the sofa frame flipping is perpendicular to the rotation axis of the rotating frame 2.

[0029] like Figure 4 , Figure 6 and Figure 7 As shown, the support frame 8 is fixedly connected to two second electric push rods 9 symmetrically distributed on the left and right. The second electric push rods 9 are electrically connected to the control terminal. The telescopic part of the second electric push rod 9 is detachably connected to the connecting plate 10. The axis of the limiting block 11 is misaligned with that of the second electric push rod 9 so that the limiting block 11 is misaligned with the backrest of the sofa frame. The two connecting plates 10 are fixedly connected to opposite sides of the limiting block 11. The telescopic part of the second electric push rod 9 is used to drive the adjacent connecting plate 10 to move so that the limiting block 11 moves. The distance between the two limiting blocks 11 is adjusted so as to fix sofa frames of different widths, increase the stability of the sofa frame during the flipping process, and thus improve the safety of the sofa frame production process. Furthermore, the movement of the two limiting blocks 11 pushes the sofa frame to move horizontally, thereby improving the convenience of moving the sofa frame. The thickness of the limiting block 11 gradually increases from the axis of the rotating frame 2 to the distance away so that the limiting block 11 can fix sofa frames of different thicknesses.

[0030] The specific working principle is as follows:

[0031] When the operator needs to use this device to flip the sofa frame, the operator removes the connecting plate 10 from the telescopic part of the second electric push rod 9. The sofa frame is then transported to the rotating frame 2 via the rotating roller of the worktable 1. The connecting plate 10 is then installed onto the telescopic part of the second electric push rod 9. At this time, the sofa frame base is located on the front support block 7, and the corner of the sofa frame is located on the support frame 8. The operator activates the two second electric push rods 9 via the control terminal. The telescopic parts of the two second electric push rods 9 retract, and the telescopic parts of the second electric push rods 9 move the limiting blocks 11 via the connecting plate 10. The two limiting blocks 11 move in opposite directions to fix the left and right sides of the sofa frame. Then, the operator closes the two second electric push rods 9 via the control terminal. By fixing the sofa frame, the probability of displacement or even injury to the operator during the subsequent sofa frame flipping process is reduced, thereby improving the safety of the sofa frame flipping process.

[0032] After the sofa frame is fixed, the operator processes the sofa frame. When the operator needs to flip the sofa frame, the two first electric push rods 4 are activated through the control terminal. The telescopic parts of the two first electric push rods 4 drive the adjacent top frame 6 to move upward through the adjacent sliding pins 5. The top frame 6 drives the adjacent support block 7 to move upward. The front support block 7 drives the sofa frame base to move upward, so that the sofa frame gradually flips. The sofa frame drives the support frame 8 to rotate. As the sofa frame flips, the backrest of the sofa frame gradually presses against the rear support block 7.

[0033] When the two support blocks 7 are respectively attached to the sofa frame base and the backrest of the sofa frame, the operator controls the telescopic part of the rear first electric push rod 4 to move downward through the control terminal, while the telescopic part of the front first electric push rod 4 continues to move upward. The telescopic part of the rear first electric push rod 4 drives the adjacent support block 7 to move downward through the adjacent sliding pin 5 and the adjacent top frame 6. The rear support block 7 supports the sofa frame, allowing the sofa frame to be slowly flipped backward to reduce the probability of damage during the flipping process. The sofa frame is flipped by the push of the two support blocks 7. After the sofa frame has finished flipping, the telescopic part of the front first electric push rod 4 drives the adjacent support block 7 to move downward and reset through the adjacent sliding pin 5 and the adjacent top frame 6. The operator then closes the two first electric push rods 4 through the control terminal.

[0034] During the production of the sofa frame, if it is necessary to process the side of the sofa frame, taking the processing of the left side of the sofa frame as an example, the motor 3 is turned on by the control terminal. The output shaft of the motor 3 drives the rotating frame 2 to rotate through the gear shaft. The rotating frame 2 drives the two top frames 6 to rotate. The sliding pin 5 moves in the adjacent sliding groove 601. After the rotating frame 2 drives the sofa frame to rotate, the telescopic part of the first electric push rod 4 can still drive the top frame 6 to move upward through the sliding pin 5. The support block 7 drives the sofa frame to flip, so that the position of the flip axis of the sofa frame changes, thereby increasing the flip-able form of the sofa frame and improving the ease of operation in the production process of the sofa frame.

[0035] During the production of the sofa frame, the above steps are repeated to flip the sofa frame, facilitating processing of various parts of the sofa frame. After the sofa frame is processed, the operator controls the output shaft of motor 3 to rotate and reset via the control terminal. The output shaft of motor 3 drives the rotating frame 2 to reset. Then, the operator activates the two first electric push rods 4 via the control terminal, controlling the telescopic parts of the two first electric push rods 4 to move downwards and reset. The telescopic parts of the first electric push rods 4 drive the top frame 6 to reset via the sliding pin 5. The top frame 6 drives the support block 7 to reset. One of the support blocks 7 supports the sofa frame during the reset process. After the support block 7 is reset, the operator closes the two first electric push rods 4 and activates the two second electric push rods 9 via the control terminal. The telescopic parts of the second electric push rods 9 drive the limit block 11 to reset via the connecting plate 10. The connecting plate 10 is removed from the telescopic parts of the second electric push rods 9, and the sofa frame is transported by the rotating rollers of the worktable 1. After the sofa frame is removed, the connecting plate 10 is installed on the telescopic parts of the second electric push rods 9.

[0036] Example 2

[0037] Based on Example 1, such as Figure 5 and Figure 7 As shown, a flexible block 12 is fixed to the limiting block 11. The flexible block 12 is used to fit the sofa frame. A flexible part 13 is provided above the top frame 6. The flexible part 13 is used to fit the sofa frame to reduce the probability of the wooden sofa frame being worn or even crushed during the flipping process, thereby improving the quality of the wooden sofa frame after production. The upper side of the flexible part 13 is lower than the upper side of the rotating frame 2 so that the sofa can be moved above the flexible part 13.

[0038] Example 3

[0039] Based on Example 2, such as Figure 7 and Figure 8 As shown, the support frame 8 is slidably connected to a sliding plate 15, and a flexible pad 16 is fixedly connected to the sliding plate 15. The flexible pad 16 is provided with several protrusions 17. The protrusions 17 increase the frictional resistance encountered when the sofa frame moves. During the horizontal movement of the sofa frame (such as when the extension and retraction parts of the two second electric push rods 9 drive the limit block 11 to move through the connecting plate 10 to adjust the position of the sofa frame and make the sofa frame move horizontally), the sofa frame drives the flexible pad 16 and the sliding plate 15 to move horizontally through the protrusions 17, so as to reduce the probability of relative displacement between the sofa frame and the supported point, thereby reducing the probability of wear caused by movement during the production process of the sofa frame, and thus improving the quality of the sofa frame after production.

[0040] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
