[0041] Example:
[0042] like Figure 1-6 As shown, this application discloses a paper tray folding fixture, comprising:
[0043] A fixing part 10 includes two fixing devices 11. Specifically, the fixing device 11 includes a fixing base 111 and a sealing plate 112. A material groove is provided on the upper surface of the fixing base 111. The material groove is adapted to the shape of the paper tray. The sealing plate 112 is detachably sealed to the material groove. During operation, the non-folded end of the paper tray, i.e. the main body of the paper tray, is placed in the material groove. The sealing plate 112 is sealed to the material groove by a snap fastener, so that the paper tray is restricted in the material groove.
[0044] A clamping part 20 is disposed opposite to the fixing part 10. It includes a clamping plate 21, which includes six clamping heads 22, wherein every three clamping heads 22 correspond to a fixing device 11, thereby enabling the clamping part 20 to apply clamping force evenly to the paper tray, ensuring that the paper tray can be bent evenly. During operation, the clamping heads 22 clamp the folded part of the paper tray near the bending point, wherein the bending point is located between the folded part and the non-folded part of the paper tray.
[0045] A drive source 30 drives the clamping part 20 to rotate. Specifically, the drive source 30 is a motor. When working, the motor drives the clamping part 20 to rotate, and the clamping head 22 on the clamping part 20 drives the folding part of the paper tray to fold. After folding, the folding part of the paper tray is folded together with the non-folding part, which not only has high production efficiency, but also makes it easier to maintain the shape after folding.
[0046] Specifically, it also includes a Hall sensor 40 and a magnet 961 for measuring the rotation angle of the clamping part 20. Since a magnet 961 is provided on the rotating shaft 96, when the rotating shaft rotates, the Hall sensor 40 will detect the change in the direction or intensity of the magnetic field, and then calculate the rotation angle of the rotating shaft, and then measure the rotation angle of the clamping plate 21. Therefore, in order to make it easier for the paper tray to maintain its shape after folding, the Hall sensor 40 usually sends a signal to the control system when it detects that the rotation angle of the rotating shaft 96 is 181-185 degrees, and the control system controls the motor to stop working.
[0047] Specifically, it also includes a base plate 50 and a first upright plate 60, a second upright plate 70, and a third upright plate 80 arranged side by side on the base plate 50. The first upright plate 60 and the second upright plate 70 are disposed at one end of the base plate 50, and the third upright plate 80 is disposed at the other end of the base plate 50. The fixing part 10 and the clamping part 20 are both disposed between the second upright plate 70 and the third upright plate 80. The second upright plate 70 and the third upright plate 80 are used to support the clamping part. The driving source 30 is disposed on the side of the first upright plate 60 opposite to the second upright plate 70. The first upright plate 60 is used to support the driving source. A first housing 61 is sealed between the first upright plate 60 and the second upright plate 70. A second housing 81 is sealed on the side of the third upright plate 80 opposite to the second upright plate 70.
[0048] Specifically, a transmission structure 90 is provided between the drive source 30 and the clamping part 20. The transmission structure 90 includes a first driving wheel 91, a first driven wheel 92, a second driven wheel 93, a third driven wheel 94, and a first rotating rod 95. The first driving wheel 91 is located on the side of the first upright plate 60 opposite to the drive source 30 and is connected to the drive source 30. The first driven wheel 92 meshes with the first driving wheel 91. The second driven wheel 93 is coaxially arranged with the first driven wheel 92. The third driven wheel 94 meshes with the second driven wheel 93 and is coaxially arranged with the first rotating rod 95. The first rotating rod 95 is located on the side of the second upright plate 60 opposite to the drive source 30. On one side of the third driven wheel 94, the pitch circle diameter of the first driving wheel 91 is smaller than that of the second driven wheel 93, and the pitch circle diameter of the second driven wheel 93 is smaller than that of the first driven wheel 92. The pitch circle diameters of the second driven wheel 93, the third driven wheel 94, the fourth driven wheel 97, and the fifth driven wheel 99 are the same. Through the above structural design, by pairing gears of different sizes, high-speed, low-torque motion on the input shaft can be converted into low-speed, high-torque motion on the output shaft, and vice versa. At the same time, it is more efficient than other forms of power transmission such as belts or chains because the slippage between them is very small, which means less energy loss and more efficient transmission of power from one component to another.
[0049] Specifically, the second driven wheel 93 and the first driven wheel 92 are coaxially arranged via a rotating shaft 96. The rotating shaft 96 is rotatably mounted on the first upright plate 60, the second upright plate 70, and the third upright plate 80 via bearings. A fourth driven wheel 97 is arranged on the side of the third upright plate 80 away from the second upright plate 70. The rotating shaft 96 is provided with a magnet 961. The rotation angle of the rotating shaft 96 is detected by the cooperation of the magnet 961 and the Hall sensor 40.
[0050] Specifically, the first rotating rod 95 is connected to one end of the clamping plate 21, and the other end of the clamping plate 21 is connected to a second rotating rod 98. The second rotating rod 98 is coaxially arranged with a fifth driven wheel 99. The fifth driven wheel 99 is located on the side of the third upright plate 80 away from the second upright plate 70, and the fifth driven wheel 99 meshes with the fourth driven wheel 97.
[0051] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, high efficiency, and strong practicality.
[0052] As a further embodiment of this utility model, the above description, in conjunction with specific preferred embodiments, provides a more detailed explanation of the utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this utility model, and all such modifications and substitutions should be considered within the scope of protection of this utility model.
