[0030] In addition, Figure 1-Figure 4 As shown, the present application also provides a first pressing platform 2 and a second pressing platform 3 for stacking the bonded writing boards. The first pressing platform 2 and the second pressing platform 3 are both slidably arranged on the bottom plate 10 along the length direction of the bottom plate 10, and the second pressing platform 3 and the first pressing platform 2 can be alternately moved to the bottom of the pressing plate 13, so that the pressing plate 13 can press the writing board on the corresponding pressing platform. Specifically, as shown in 1 and Figure 4As shown, two inner slide grooves 16 and two outer slide grooves 17 are provided on the bottom plate 10; the inner slide grooves 16 and the outer slide grooves 17 are both arranged along the length direction of the bottom plate 10, and the two inner slide grooves 16 are symmetrically arranged on the bottom plate 10 along the length direction of the bottom plate 10, and the two outer slide grooves 17 are symmetrically arranged on both sides of the inner slide grooves 16.

When the present application is actually used, a part of the bonded writing board can be stacked on the first pressing platform 2, and then the first pressing platform 2 can be slid to the bottom of the pressing plate 13, and the pressing plate 13 can be pressed against the bonded writing board, and then the pressing time can be set. While the pressing plate 13 is pressing the part of the writing board, the bonded writing board can be stacked on the second pressing platform 3. When the writing board on the first pressing platform 2 is pressed, the writing board can be taken away, and then the first pressing platform 2 is moved to the Figure 1 Slide the second pressing platform 3 to the right side of the pressing plate 13, and at the same time slide the second pressing platform 3 to the bottom of the pressing plate 13, that is, Figure 1 The second pressing platform 3 and the first pressing platform 2 are respectively connected to different slide grooves for sliding, and the first pressing platform 2 is slightly lower than the second pressing platform 3, so the first pressing platform 2 can slide under the second pressing platform 3 without affecting each other.

[0031] Specifically, Figure 1 , Figure 2 and Figure 5 As shown, in the present application, the four corners of the bottom of the first press-fitting platform 2 are respectively vertically and fixedly provided with first connecting rods 20, and the first connecting rods 20 on both sides of the first press-fitting platform 2 respectively pass through the two inner slide grooves 16 and are slidably connected with the inner slide grooves 16. A first plate 21 is passed through the bottom of the first connecting rod 20, and a first slider 22 is provided on the upper side of the first plate 21, and a first slide rail 23 cooperating with the first slider 22 is correspondingly provided on the bottom surface of the bottom plate 10. Figure 5 As shown, in this embodiment, the first flat plate 21 is also rectangular, and first sliders 22 are fixedly disposed on both sides of the upper surface of the first flat plate 21, and two first slide rails 23 cooperating with the two first sliders 22 are correspondingly disposed on the bottom surface of the bottom plate 10. Figure 1 , Figure 3 and Figure 5As shown, the four corners of the bottom of the second press-fitting platform 3 are respectively vertically and fixedly provided with second connecting rods 30, and the second connecting rods 30 on both sides of the second press-fitting platform 3 respectively pass through the two outer slide grooves 17 and are slidably connected with the outer slide grooves 17. A second flat plate 31 is passed through the bottom of the second connecting rod 30, and in this embodiment, the second flat plate 31 is also rectangular, and vertical plates 34 are respectively fixedly provided on both sides of the second flat plate 31, and a second slider 32 is fixedly provided on the top of the vertical plate 34, and a second slide rail 33 matching the second slider 32 is correspondingly provided on the bottom surface of the bottom plate 10.

[0032] In this embodiment, the first flat plate 21 can be slidably set at the bottom of the base plate 10 through the cooperation of the first slide rail 23 and the first slider 22. The first connecting rod 20 at the bottom of the first press-fitting platform 2 is penetrated on the first flat plate 21. When the first flat plate 21 slides, the first press-fitting platform 2 is also driven to slide through the first connecting rod 20. In addition, the second flat plate 31 can be slidably set at the bottom of the base plate 10 through the cooperation of the second slide rail 33 and the second slider 32; and the second connecting rod 30 at the bottom of the second press-fitting platform 3 is penetrated on the second flat plate 31. When the second flat plate 31 slides, the second press-fitting platform 3 is also driven to slide through the second connecting rod 30. In this embodiment, the lower surface of the first press-fitting platform 2 contacts the upper surface of the base plate 10 and is slidably connected to the upper surface of the base plate 10. Two second cylinders 35 are symmetrically arranged above the second flat plate 31. The output ends of the two second cylinders 35 are respectively fixedly connected to the bottom of the second press-fitting platform 3 through the outer slide groove 17, as shown in FIG. Figure 1 and Figure 4 As shown. In this embodiment, the height of the second press-fitting platform 3 can be adjusted by extending and retracting the output end of the cylinder. When the second press-fitting platform 3 is located below the pressing plate 13, the output end of the second cylinder 35 can drive the second press-fitting platform 3 to descend, and make the bottom of the second press-fitting platform 3 contact the bottom plate 10, so that the bottom plate 10 can fully bear the pressure of the pressing plate 13, and will not cause damage to the second cylinder 35 and the second connecting rod 30. When the second press-fitting platform 3 needs to leave the bottom of the pressing plate 13, the output end of the second cylinder 35 can drive the second press-fitting platform 3 to rise, and rise to a position higher than the first press-fitting platform 2, so that the second press-fitting platform 3 can slide over the top of the first press-fitting platform 2.

[0033] like Figure 4 and Figure 5As shown, in this embodiment, a control mechanism 4 is further provided below the bottom plate 10 to drive the first pressing platform 2 and the second pressing platform 3 to move alternately to the position directly below the pressing plate 13. The control mechanism 4 includes a transmission belt 40, two transmission wheels 41 and a motor 42. The transmission wheels 41 are respectively rotatably arranged at both ends of the length direction of the bottom plate 10. The motor shaft of the motor 42 is fixedly connected to the center of one of the transmission wheels 41. The transmission belt 40 is sleeved on the two transmission wheels 41 and is divided into two sides, namely, a transmission belt A side 400 and a transmission belt B side 401. The bottom of the first flat plate 21 is fixedly connected to the transmission belt 40 on one side, that is, fixedly connected to the transmission belt A side 400. The bottom of the second flat plate 31 is fixedly connected to the transmission belt 40 on the other side, that is, fixedly connected to the transmission belt B side 401. Specifically, a first connector 25 is provided at the bottom of the first press-fitting platform 2, and the first connector 25 is fixedly connected to the transmission belt 40 on one side; a second connector 36 is provided at the bottom of the second press-fitting platform 3, and the second connector 36 is fixedly connected to the transmission belt 40 on the other side.

[0034] In this embodiment, the motor 42 provides power to drive the transmission wheel 41 and the transmission belt 40 to rotate; wherein the motor 42 can be a stepper motor, and when the transmission belt 40 rotates, the first connector 25 and the second connector 36 respectively drive the first plate 21 and the second plate 31 to move in opposite directions, thereby realizing the first press-fitting platform 2 and the second press-fitting platform 3 to move alternately to the bottom of the pressing plate 13. In this application, the motor 42 is set to a mode of alternating forward and reverse rotation, thereby realizing the alternating movement of the first press-fitting platform 2 and the second press-fitting platform 3. Embodiment 2

[0035] In this embodiment, if Figure 1 and Figure 2As shown, a central through slot 18 is provided at the center of the bottom plate 10, and the central through slot 18 is provided along the length direction of the bottom plate 10, and the central through slot 18 is located between the two inner slide slots 16. In addition, a third cylinder 24 is fixedly provided on the first flat plate 21, and the output end of the third cylinder 24 passes through the central through slot 18 and is fixedly connected to the first press-fitting platform 2. In this embodiment, the height of the first press-fitting platform 2 can be adjusted by the third cylinder 24; that is, when the first press-fitting platform 2 is located below the pressing plate 13, the output end of the third cylinder 24 can be retracted, driving the first press-fitting platform 2 to descend, so that the bottom of the first press-fitting platform 2 contacts the bottom plate 10, that is, the same state as the first press-fitting platform 2 in the embodiment, thereby enabling the bottom plate 10 to fully bear the pressure of the pressing plate 13 during the pressing process, and will not cause damage to the third cylinder 24 and the first connecting rod 20. When the first press platform 2 needs to leave from under the press plate 13, the output end of the third cylinder 24 can drive the first press platform 2 to rise slightly, so that only the bottom surface of the first press platform 2 leaves the upper surface of the base plate 10, but the first press platform 2 is still lower than the second press platform 3. Therefore, when the first press platform 2 moves, its bottom surface will not rub against the upper surface of the base plate 10, and both will not wear out.

[0036] It is worth noting that a controller may be provided in the present application, wherein the first cylinder 14, the second cylinder 35, the third cylinder 24 and the motor 42 are all electrically connected to the controller, and the operation process and state thereof are uniformly controlled by the controller.
