Detailed implementation mode

[0041] Referring to an embodiment herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0042] Embodiment 1: An automatic stacking press for processing composite boards, refer to Figures 1 - 12 , including:

[0043] The main frame 1, on which a press body 2 is installed, and the press body 2 includes an upper hot pressing plate 21 and a lower hot pressing plate 22, as shown in Figure 6 and Figure 7As shown, the lower hot pressing plate 22 is provided with a through groove 221, and a plurality of through holes 222 are provided at the rear of the lower hot pressing plate 22;

[0044] The rear hot pressing plate 3 is fixedly connected at the through holes 222;

[0045] The front hot pressing plate 4 is movable in the Z-axis and is arranged at the through groove 221;

[0046] The side hot pressing plates 5, the number of which is two, are movable in the Z-axis and are arranged at the through groove 221. The rear hot pressing plate 3, the front hot pressing plate 4 and the side hot pressing plates 5 are all hollow and open at the bottom, so that the steam inside the lower hot pressing plate 22 can enter the rear hot pressing plate 3, the front hot pressing plate 4 and the side hot pressing plates 5;

[0047] The connecting frame 6 is welded to the left side of the main frame 1;

[0048] The electric conveying roller 7 and the electric conveying roller 8 are installed in the middle of the connecting frame 6;

[0049] The lifting rod 9 is movable in the XZ plane and is arranged above the electric conveying roller 8. Two rows of recessed parts 81 are provided on the electric conveying roller 8. The two lifting rods 9 are respectively located at the two rows of recessed parts 81, and the top surface height of the lifting rod 9 is lower than the top height of the electric conveying roller 8, so that the lifting rod 9 does not affect the conveying of the composite board 14 by the electric conveying roller 8;

[0050] The right-angle rods 10, the number of which is two, are movable in the Y-axis and are arranged on the left side of the connecting frame 6;

[0051] The vertical rods 11, the number of which is two, are respectively fixedly connected to the middle parts of the two right-angle rods 10. As Figure 12 shown, right-angle grooves 100 matching the composite board 14 are provided on both the right-angle rods 10 and the vertical rods 11. A slope 110 is provided at the top end of the vertical rod 11. When the two right-angle rods 10 approach each other and the two vertical rods 11 approach each other, the position of the composite board 14 is restricted by the right-angle grooves 100 and the slope 110, so that the composite board 14 is stacked neatly.

[0052] Reference Figures 1 - 4 also includes a pushing mechanism for pushing out the pressed composite board 14. The pushing mechanism includes an electric push rod 54, a connecting rod 55 and a pushing plate 56. The electric push rod 54 is bolted to the right side of the main frame 1. A connecting rod 55 is fixedly connected to the telescopic rod of the electric push rod 54. A pushing plate 56 is fixedly connected to the left end of the connecting rod 55. When the pushing plate 56 moves leftward, it can push the composite board 14 on the lower hot pressing plate 22.

[0053] Reference Figures 1 - 6, further comprising a driving mechanism for driving the front hot pressing plate 4 and the side hot pressing plates 5 to move in the Z-axis direction. The driving mechanism includes an electric push rod 41, guide rods 51, a lifting frame 52, and a pressing block 53. The electric push rod 41 is bolted to the front side of the main frame 1, and the telescopic rod of the electric push rod 41 is fixedly connected to the front hot pressing plate 4. A pair of guide rods 51 are fixedly connected to the left and right sides of the main frame 1 respectively. The lifting frame 52 is slidably connected to the four guide rods 51, and a return spring is fixedly connected between the lifting frame 52 and the main frame 1. The two side hot pressing plates 5 are fixedly connected to the lifting frame 52, and a pressing block 53 is fixedly connected to the right part of the lifting frame 52. An inclined part is provided on the upper part of the pressing block 53. When the push plate 56 and the connecting rod 55 move leftward, the push plate 56 will squeeze the inclined part to cause the pressing block 53 to descend. When the push plate 56 and the connecting rod 55 continue to move leftward, the connecting rod 55 will press the pressing block 53 to keep the pressing block 53 in a descending state.

[0054] Reference Figure 1 、 Figure 8 、 Figure 9 and Figure 10 , further comprising a control mechanism for controlling the movement of the lifting rod 9. The control mechanism includes a connecting plate 90 and a two-dimensional moving platform 91. The two-dimensional moving platform 91 is provided on the upper part of the connecting frame 6, and the connecting plate 90 is provided on the two-dimensional moving platform 91. The two-dimensional moving platform 91 controls the connecting plate 90 to move in the XZ plane, and the two lifting rods 9 are fixedly connected to the connecting plate 90.

[0055] Reference Figure 8 、 Figure 10 and Figure 11 , further comprising slide rods 101 and triangular blocks 102. A pair of slide rods 101 are slidably connected to the front and rear parts of the connecting frame 6 respectively, and return springs are fixedly connected between the slide rods 101 and the connecting frame 6. The two right-angle rods 10 are fixedly connected to the two pairs of slide rods 101 respectively, and triangular blocks 102 are fixedly connected to the middle parts of the right-angle rods 10. The triangular blocks 102 are all abutted against the connecting plate 90. When the connecting plate 90 moves leftward, the two right-angle rods 10 approach each other under the action of the return springs. When the connecting plate 90 resets, the connecting plate 90 will squeeze the two triangular blocks 102 to cause the two right-angle rods 10 to move away from each other.

[0056] Initially, a composite board 14 to be pressed is placed on the lower hot pressing plate 22, and the rear hot pressing plate 3, the front hot pressing plate 4, and the two side hot pressing plates 5 are respectively in contact with the four side surfaces of the composite board 14; the triangular blocks 102 are all abutted against the connecting plate 90, and the return springs are in a compressed state; a support plate 13 for placing the composite board 14 is placed below the right-angle rods 10.

[0057] The pressing method of the press body 2 is a prior art. In this embodiment, the heat medium of the press body 2 is specifically steam. First, control the press body 2 to lower the upper hot pressing plate 21. The upper hot pressing plate 21 and the lower hot pressing plate 22 press the composite board 14. At the same time, since the rear hot pressing plate 3, the front hot pressing plate 4, and the side hot pressing plates 5 are all hollow and open at the bottom, the steam inside the lower hot pressing plate 22 enters the rear hot pressing plate 3 through the through holes 222, and the steam inside the lower hot pressing plate 22 enters the front hot pressing plate 4 and the side hot pressing plates 5 through the through grooves 221. Thus, the surfaces of the rear hot pressing plate 3, the front hot pressing plate 4, and the side hot pressing plates 5 are all in a high-temperature state. The four sides of the composite board 14 can be heated by the rear hot pressing plate 3, the front hot pressing plate 4, and the two side hot pressing plates 5, so that the composite board 14 is fully heated, avoiding the problem of delamination at the edge of the composite board 14, and the pressing effect is good.

[0058] When the pressing of the composite board 14 is completed, control the electric push rod 41 to drive the front hot pressing plate 4 to descend along the Z-axis, control the electric push rod 54 to drive the connecting rod 55 to move leftward along the X-axis, and the push plate 56 moves together with the connecting rod 55. When the push plate 56 contacts the inclined part of the lower pressing block 53, the push plate 56 will squeeze the lower pressing block 53 to descend along the Z-axis, and the lifting frame 52 and the two side hot pressing plates 5 descend together with the lower pressing block 53, and the return spring is compressed. At this time, both the front hot pressing plate 4 and the side hot pressing plates 5 are separated from the composite board 14. The push plate 56 continues to move leftward, the push plate 56 will cross over the lower pressing block 53, and the connecting rod 55 will continue to press the lower pressing block 53 to keep the lower pressing block 53 in the descending state. The push plate 56 can then push the composite board 14 onto the electric conveying roller 7; then control the electric push rod 54 to drive the connecting rod 55 to move rightward along the X-axis to reset, the push plate 56 moves rightward, the push plate 56 will cross over the lower pressing block 53. When the push plate 56 is separated from the lower pressing block 53, the return spring restores, driving the lifting frame 52, the side hot pressing plate 5, and the lower pressing block 53 to rise and reset. Then place the next composite board 14 to be pressed on the lower hot pressing plate 22, and control the electric push rod 41 to drive the front hot pressing plate 4 to rise and reset. Similarly, the press body 2 can be controlled to press the next composite board 14.

[0059] Control the electric conveying roller 7 to convey the pressed composite board 14 leftward onto the electric conveying roller 8. Since the two lifting rods 9 are respectively located at the two rows of recessed parts 81, the top surface height of the lifting rods 9 is lower than the top height of the electric conveying roller 8, and the lifting rods 9 will not block the composite board 14. Control the electric conveying roller 8 to rotate counterclockwise, so that the composite board 14 is conveyed above the two lifting rods 9.

[0060] Then control the two-dimensional moving platform 91 to raise the connecting plate 90 and the lifting rod 9 in the Z-axis direction. The two lifting rods 9 lift the composite plate 14, separating the composite plate 14 from the second electric conveying roller 8. Then control the two-dimensional moving platform 91 to move the connecting plate 90, the lifting rod 9, and the composite plate 14 to the left in the X-axis direction. When the connecting plate 90 separates from the triangular block 102, the return spring restores, driving the pair of front sliding rods 101 to move backward and driving the pair of rear sliding rods 101 to move forward. The triangular block 102, the right-angle rod 10, and the vertical rod 11 move synchronously with the sliding rod 101. The two right-angle rods 10 approach each other, and the two vertical rods 11 approach each other. When the lifting rod 9 moves the composite plate 14 to directly above the support plate 13, control the two-dimensional moving platform 91 to lower the connecting plate 90, the lifting rod 9, and the composite plate 14 in the Z-axis direction. The inclined surface 110 can correct the position of the composite plate 14 in the X-axis direction, so that the four corners of the composite plate 14 are all located in the right-angle grooves 100. Then control the two-dimensional moving platform 91 to continue moving the connecting plate 90 and the lifting rod 9 to the left. Since the four corners of the composite plate 14 are all located in the right-angle grooves 100, the composite plate 14 will be blocked by the right-angle rod 10, and the lifting rod 9 can be separated from the composite plate 14. The composite plate 14 falls and is neatly stacked on the support plate 13. The stacking is automated and the working efficiency is high. Control the two-dimensional moving platform 91 to raise the connecting plate 90 and the lifting rod 9 and then move them to the right to the initial position. When the connecting plate 90 contacts the triangular block 102, the connecting plate 90 will squeeze the two triangular blocks 102. The two triangular blocks 102 move away from each other, driving the two right-angle rods 10 to move away from each other and driving the two vertical rods 11 to move away from each other. The return spring is compressed, and the four corners of the composite plate 14 on the support plate 13 leave the right-angle grooves 100. If the stacking of the composite plates 14 on the support plate 13 is completed at this time, the staff can fork away the support plate 13 with a forklift.

[0061] Embodiment 2: On the basis of Embodiment 1, referring to Figure 1 , Figure 8 and Figure 13 , it further includes a support plate conveying mechanism. The support plate conveying mechanism includes a belt conveyor and a placement frame 123. A belt conveyor is installed at the lower part of the connecting frame 6. The belt conveyor includes a conveyor belt 121. Multiple pushing parts 122 are arranged at intervals on the conveyor belt 121. The lower part of the connecting frame 6 is connected with a placement frame 123 located above the conveyor belt 121. A material passing opening for the pushing part 122 to pass through is opened at the lower part of the placement frame 123.

[0062] After the pallet 13 of the stacked composite board 14 is lifted by a forklift, control the belt conveyor to rotate the conveyor belt 121 counterclockwise. The pusher 122 pushes a pallet 13 at the material passing opening to move leftward, and the lowermost pallet 13 in the placement frame 123 will continue to fall to the material passing opening. Thus, through the cooperation of the pusher 122 and the placement frame 123, the pallet 13 is automatically moved under the right-angle rod 10, and the composite board 14 can continue to be neatly stacked on the pallet 13, making the processing of the composite board 14 more automated.

[0063] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.

Then control the two-dimensional moving platform to move the connecting plate, the material lifting rod and the composite board to the left along the X-axis. After the connecting plate separates from the triangular block, the return spring restores, driving a pair of front slide rods to move backward and driving a pair of rear slide rods to move forward. The triangular block, the right-angle rod and the vertical rod move synchronously with the slide rods. The two right-angle rods approach each other, and the two vertical rods approach each other. After the material lifting rod moves the composite board to directly above the pallet, control the two-dimensional moving platform to lower the connecting plate, the material lifting rod and the composite board along the Z-axis. The position of the composite board in the X-axis direction can be corrected through the inclined plane, so that the four corners of the composite board are all located in the right-angle grooves. Then control the two-dimensional moving platform to continue moving the connecting plate and the material lifting rod to the left. Since the four corners of the composite board are all located in the right-angle grooves, the composite board will be blocked by the right-angle rods, and the material lifting rod can be separated from the composite board. The composite board falls and is neatly stacked on the pallet.
