[0038] Example 1

[0039] See also Figures 1 to 5 As shown:

[0040] The utility model provides a folding mechanism, comprising: a pressing component C installed above a box body A, an abutting component D, a transverse folding component E and a vertical folding component F.

[0041] In actual application, the transverse folding component E is used to fold the folded edge B of the processed box body A that protrudes from the frame from a vertical state to a horizontal state; the vertical folding component F is used to fold the folded edge B from a horizontal state to fit the inner wall of the frame; and the pressing component C is used to fix the box body A, and the abutment component D is used to press the side wall of the folded edge B of the box body A from the inside of the side wall, so that when the transverse folding component E and the vertical folding component F fold the folded edge B, the abutment component D can fix and support the side wall of the folded edge B, so that the overall folding effect is better.

[0042] Through such an arrangement, the problem that the existing box body A is easily deformed due to lack of support when folding is solved, and the folding effect of the entire folding mechanism is improved.

[0043] It also includes a first driving mechanism and a second driving mechanism; the first driving mechanism connects the pressing component C, the abutting component D and the transverse folding component E; the second driving mechanism connects the vertical folding component F.

[0044] Through such an arrangement, the folding mechanism can simultaneously perform pressing, abutting support and folding actions when folding the edge B to be folded of the box body A, thereby saving the process and time of folding the box body A in steps in the past, and improving the folding efficiency of the box body A by the entire mechanism.

[0045] In actual application, the first driving mechanism is mainly composed of a driving fixing plate 10 , a motor 20 and a transmission bracket 11 .

[0046] The driving fixed plate 10 is arranged in the vertical direction and fixed on the bracket of the production line. One end of the transmission bracket 11 is fixedly connected to one side of the driving fixed plate 10; the first crank 22 and the second crank 23 are respectively disposed on both sides of the other end of the transmission bracket 11.

[0047] A synchronous belt 21 is provided inside the transmission bracket 11, and the motor 20 is installed at the connection between the driving fixed plate 10 and the transmission bracket 11, and the motor shaft of the motor 20 is connected to one end of the synchronous belt 21; the other end of the synchronous belt 21 is connected to both the first crank 22 and the second crank 23.

[0048] Through such an arrangement, the motor 20 can drive the first crank 22 and the second crank 23 to rotate at the same time.

[0049] The pressing assembly C is connected to the second crank 23, and the abutting assembly D is connected to both the first crank 22 and the second crank 23. The abutting assembly D can not only move in the vertical direction under the drive of the first crank 22 and the second crank 23, but also apply a horizontal thrust to the side wall of the box body A to be folded B, so that it can be pressed tightly; and the transverse folding assembly E is connected to the first crank 22, and moves in the horizontal direction under the drive of the first crank 22. Through such a design, the side wall of the box body A to be folded B can be fixed and folded in the horizontal direction at the same time, thereby saving the folding time and improving the folding efficiency.

[0050] The pressing assembly C is mainly composed of a horizontal connecting plate 41 , a vertical plate 42 , and a U-shaped pressing plate 43 ; the abutting assembly D is composed of a side wall supporting plate 44 and a first horizontal slide rail 45 .

[0051] One end of the horizontal connecting plate 41 is connected to the second crank 23, and the other end is vertically connected to one side of the vertical plate 42; and a vertical slide rail is provided between the vertical plate 42 and the driving fixed plate 10, so that the other side of the vertical plate 42 forms a sliding connection with one side of the driving fixed plate 10.

[0052] With this arrangement, when the second crank 23 rotates, it can drive the horizontal connecting plate 41 to reciprocate in the vertical direction, and further drive the vertical plate 42 to slide back and forth in the vertical direction on one side of the driving fixed plate 10 .

[0053] A U-shaped pressing plate 43 is vertically connected to the bottom of the vertical plate 42, so that the U-shaped pressing plate 43 can be driven to move synchronously during the reciprocating motion of the vertical plate 42 in the vertical direction. The U-shaped plate surface of the U-shaped pressing plate 43 can press the three edges of the box body A, thereby pressing and fixing the box body A.

[0054] In order to improve the pressing effect of the U-shaped pressing plate 43 on the box body A, vertical connecting rods 46 are arranged on both sides of the U-shaped pressing plate 43, and the vertical connecting rods 46 are vertically connected to both sides of the bottom of the vertical plate 42, and the length of the vertical connecting rods 46 can be adjusted. This allows the operator to adjust the length of the vertical connecting rods 46 before the folding mechanism works, thereby adjusting the distance between the U-shaped pressing plate 43 and the bottom of the vertical plate 42.

[0055] A slider is provided on the first horizontal slide rail 45, and the slider is fixedly connected to the bottom of the vertical plate 42. In actual use, the side wall support plate 44 is set to be bent, and the top of the side wall support plate 44 is connected to the bottom of one end of the first horizontal slide rail 45, and the bottom of the side wall support plate 44 is used to abut against the side wall of the folded edge B of the box body A; the other end of the first horizontal slide rail 45 is connected to the first crank 22 through a connecting piece.

[0056] Through such an arrangement, the side wall support plate 44 can move in the vertical direction driven by the vertical plate 42, so that it can enter the box body A. At the same time, the first horizontal slide rail 45 moves in the horizontal direction driven by the first crank 22, thereby driving the side wall support plate 44 to move in the horizontal direction, so that the side wall of the box body A to be folded B can be tightened.

[0057] The transverse folding assembly E is mainly composed of a vertical connecting frame 32, a transverse folding shovel 33, a connecting rod 34, a lever 35 and a Y-shaped horizontal connecting plate 37.

[0058] The vertical connecting frame 32 is set in a Y shape, and second horizontal guide rails 31 are provided on both sides of the top of the vertical connecting frame 32, and the top sides of the vertical connecting frame 32 are slidably connected with the second horizontal guide rails 31. The second horizontal guide rails 31 are fixed on the production line bracket, and the second horizontal guide rails 31 are perpendicular to the surface of the driving fixed plate 10.

[0059] The transverse folding shovel 33 is used to push the folded edge B of the box body A from a vertical state to a horizontal state, and the top of the transverse folding shovel 33 is connected to the bottom of the vertical connecting frame 32, and the transverse folding shovel 33 and the side wall support plate 44 move toward each other.

[0060] One end of the connecting rod 34 is hinged to the top of the vertical connecting frame 32, and the other end is hinged to one end of the lever 35; the other end of the lever 35 is hinged to one side of the Y end of the Y-shaped horizontal connecting plate 37, and the middle part of the lever 35 is hinged to the top surface of the fixed block 36, and the fixed block 36 constitutes the fulcrum of the lever 35.

[0061] The other side of the Y end of the Y-shaped horizontal connecting plate 37 is slidably connected to the connecting piece on the first crank 22 along the vertical direction. The other end of the Y-shaped horizontal connecting plate 37 is hinged to the production line bracket.

[0062] When the first crank 22 drives the connecting part to swing, it will pull one side of the Y end of the Y-shaped horizontal connecting plate 37 to swing in the horizontal direction, and then synchronously pull one end of the lever 35, and the connection between the lever 35 and the fixed block 36 becomes the turning point of the pulling force, and then the other end of the lever 35 pulls the connecting rod 34, and the connecting rod 34 pulls the vertical connecting frame 32 to reciprocate along the second horizontal guide rail 31, so that the horizontal folding shovel 33 at the bottom of the vertical connecting frame 32 also reciprocates in the horizontal direction driven by the vertical connecting frame 32.

[0063] The connecting member on the first crank 22 includes a vertical connecting plate 38 and an L-shaped connecting plate 39. The top of the vertical connecting plate 38 is connected to the first crank 22, the bottom of the vertical connecting plate 38 is connected to the top of the L-shaped connecting plate 39, and the side of the vertical connecting plate 38 is slidably connected to the other side of the Y end of the Y-shaped horizontal connecting plate 37 along the vertical direction; the bottom of the L-shaped connecting plate 39 is fixedly connected to one end of the first horizontal slide rail 45.

[0064] Through such an arrangement, the first crank 22 can drive the vertical connecting plate 38 to move in the vertical direction and swing in the horizontal direction during its rotation; since the side edge of the vertical connecting plate 38 is slidingly connected to the other side of the Y end of the Y-shaped horizontal connecting plate 37 in the vertical direction, the vertical connecting plate 38 will not have a vertical influence on the Y-shaped horizontal connecting plate 37, but can drive the Y end of the Y-shaped horizontal connecting plate 37 to swing.

[0065] When the vertical connecting plate 38 moves and swings in the vertical direction, it drives the first horizontal slide rail 45 to move in the vertical direction, and simultaneously pushes the first horizontal slide rail 45 to move in the horizontal direction, thereby driving the side wall support plate 44 to move in the horizontal direction.

[0066] The vertical folding assembly F is mainly composed of a vertical sliding component and a shoveling component. The vertical sliding component and the shoveling component are connected; the second driving mechanism is connected to the vertical sliding component, and drives the vertical sliding component to drive the shoveling component to fold the folded edge B of the box body A from a horizontal shape to fit the inner wall of the frame.

[0067] The second driving mechanism is mainly composed of a vertical driving motor 50, a third crank 51 and a connecting rod. The vertical sliding component can be set as a vertical guide rail and a vertical plate; the shoveling and folding component can be set as a vertical push plate 52.

[0068] The vertical drive motor 50 is installed on one side of the drive fixed plate 10, and the motor shaft of the vertical drive motor 50 passes through the drive fixed plate 10 and is connected to the third crank 51; the third crank 51 is connected to one end of the connecting rod, and the other end of the connecting rod is connected to the vertical plate, and the vertical plate is connected to the drive fixed plate 10 through a vertical guide rail, and the bottom of the vertical plate is connected to the vertical push plate 52.

[0069] The vertical drive motor 50 drives the third crank 51 to rotate, thereby driving the connecting rod to move back and forth in the vertical direction. Driven by the connecting rod, the vertical push plate 52 folds the folded edge B of the box body A from a horizontal shape to fit the inner wall of the frame.

[0070] The vertical drive motor 50 may also be replaced by a cylinder; the cylinder may be directly connected to the vertical push plate 52, or may be connected to a vertical guide rail, which is then connected to the vertical push plate 52 and drives the vertical push plate 52 to reciprocate in the vertical direction.
