[0021] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model. On the contrary, the embodiments of the present utility model include all variations, modifications and equivalents falling within the spirit and scope of the appended claims.

[0022] The plywood stacking device according to an embodiment of the present utility model will be described below in conjunction with the drawings.

[0023] As Figures 1 - 4 shown, the plywood stacking device according to an embodiment of the present utility model includes an outer shell 1, a movable seat 2, a trolley 3, a caster mechanism 4, a stacking mechanism 5 and two sets of lifting mechanisms 6.

[0024] Among them, an inlet plate opening 11 is provided at one end of the outer shell 1, and an outlet 12 is provided at the other end of the outer shell 1.

[0025] It should be noted that the board inlet 11 allows the plywood to enter the shell 1 for stacking, and the outlet 12 is used to take out the plywood after stacking. Since a large number of plywood need to be taken out after stacking, the area of ​​the outlet 12 is larger. The board inlet 11 is in the upper end area of ​​the shell 1 and is used to connect the conveyor belt.

[0026] The movable seat 2 is arranged in the housing 1 , a snap-fitting groove is provided on the movable seat 2 , and the trolley 3 is arranged on the movable seat 2 , and the bottom of the trolley 3 is located in the snap-fitting groove.

[0027] It should be noted that the movable seat 2 supports the cart 3 and the plywood to be stacked. The engaging grooves on the movable seat 2 are used to accommodate the wheels of the cart 3 to restrict the cart 3 on the movable seat 2. The cart 3 is used to support and stack the plywood. The stacked plywood can be directly transported and transferred by the cart 3. No additional means are needed to transport the plywood, making it easier to move and transport the stacked plywood.

[0028] The trolley 3 is provided with a handle, which can prevent the plywood from moving further and perform a position limit constraint at one end of the plywood.

[0029] The wheel clamping mechanism 4 is disposed on the movable seat 2 , and includes a baffle 41 and a push structure 42 .

[0030] The baffle plate 41 is disposed on the movable seat 2 , the baffle plate 41 is located in the engaging groove and at one side of the trolley 3 , the pushing structure 42 is disposed on the movable seat 2 , and the pushing structure 42 is located at the bottom end of the baffle plate 41 .

[0031] It should be noted that the baffle 41 is a long strip of plate that can block the wheels of the cart 3 and directly restrict the cart 3 in the engaging groove of the movable seat 2, ensuring that the cart 3 is more stable when stacking plywood and will not shake or fall off the movable seat 2.

[0032] It can be understood that the pushing structure 42 is at the bottom end of the baffle 41, and has a control function of pushing and retracting the baffle 41. When the baffle 41 is needed to block the cart 3, the baffle 41 is pushed into the engagement groove. When the cart 3 and the plywood need to be taken out, the baffle 41 is retracted and controlled to fall down to cancel the blocking of the cart 3.

[0033] The stacking mechanism 5 is disposed in the housing 1 . The stacking mechanism 5 is located above the movable seat 2 . The stacking mechanism 5 includes a guide roller set 51 , two guide wheel sets 52 and two first drivers 53 .

[0034] Among them, the guiding roller set 51 is arranged above the movable seat 2. The top surface of the guiding roller set 51 is connected to the inner wall of the outer shell 1. The two guiding wheel sets 52 are respectively arranged on both sides of the trolley 3. The two first drivers 53 are respectively arranged at both ends of the outer shell 1, and the two first drivers 53 are respectively connected to the two groups of guiding wheel sets 52.

[0035] It should be noted that the guiding roller set 51 can be composed of multiple guiding rollers, brackets, gears and motors. The multiple guiding rollers are rotatably arranged on the brackets. The gears are connected to one end of the guiding rollers. An additional gear is arranged between the gears for transmission. When the motor controls the rotation of one of the gears, the entire guiding roller set 51 can generate a conveying force on the plywood surface when it fits the plywood surface, so as to conduct guiding and conveying.

[0036] The guiding wheel set 52 can be composed of multiple guiding wheels, brackets, gears and motors. The multiple guiding wheels are rotatably arranged on the brackets. The gears are connected to one end of the guiding wheels. An additional gear is arranged between the gears for transmission. When the motor controls the rotation of one of the gears, the entire guiding wheel set 52 can generate a conveying force on the plywood surface when it fits the plywood surface, so as to conduct guiding and conveying.

[0037] The first driver 53 can be a cylinder, which is used to control the movement of the two guiding wheel sets 52, and the first driver 53 can be driven synchronously.

[0038] It can be understood that both the guiding roller set 51 and the guiding wheel set 52 can drive the plywood to completely move into the outer shell 1, solve the problem that the plywood is stuck at the board inlet 11 after losing the conveying force of the conveyor belt. At the same time, the guiding wheel set 52 is controlled by the set first driver 53, and the position of the plywood can be adjusted to ensure that the plywood continuously entering the outer shell 1 is always stacked at the same position on the trolley 3, ensuring the neatness of the stacking and avoiding the occurrence of disorderly stacking problems.

[0039] Among them, the two groups of lifting mechanisms 6 are respectively arranged at both ends of the movable seat 2.

[0040] It can be understood that when the movable seat 2 rises and falls, it drives the trolley 3 to rise and fall. Only when the trolley 3 can descend in position will it not block the board inlet 11, and the plywood can continuously enter and be stacked on the trolley 3. The lifting mechanism 6 controls the trolley 3 by controlling the lifting of the movable seat 2.

[0041] Among them, a guiding support block 13 is arranged on the outer shell 1, and the guiding support block 13 is located at the bottom of the board inlet 11.

[0042] It can be understood that the guiding support block 13 is of a triangular block structure, which can fit the conveyor belt for conveying plywood outside, equivalent to an extension of the board inlet 11, ensuring that the plywood can be stably guided and supported and then enter the outer shell 1.

[0043] Specifically, the relevant staff set the device at the end of the conveyor belt, making the top surface of the guiding support block 13 flush with the surface of the conveyor belt. The conveyor belt transports the completed plywood, and the guiding support block 13 supports it. The conveying force of the conveyor belt controls the plywood to enter the feeding port 11. The relevant staff operate the guiding roller group 51, two groups of guiding wheel groups 52 and two first drivers 53, and continuously transport the plywood to the cart 3 after it is released from the control of the conveyor belt until the plywood is completely restricted by the handle limit of the cart 3 and cannot move. The first driver 53 pushes the guiding wheel group 52 to stack the plywood in the fixed area on the cart 3.

[0044] The relevant staff operate the lifting mechanism 6 to control the movable seat 2 to drive the cart 3 to descend by the thickness distance of one plywood. The plywood on the cart 3 follows the descent. The second plywood enters from the feeding port 11, and the above process is continuously repeated until the movable seat 2 moves to the bottom of the housing 1 and the plywood can no longer enter the feeding port 11, completing the stacking of a group of plywood.

[0045] The relevant staff control the pushing structure 42 to contract and drive the baffle 41 to descend, releasing the restriction on the cart 3. The cart 3 and the plywood on it are transported out of the housing 1 through the handle, and then a new cart 3 is replaced. The pushing structure 42 pushes the baffle 41 out to restrict the cart 3, and the height of the movable seat 2 and the cart 3 is lifted to continue stacking the plywood.

[0046] In an embodiment of the present utility model, as Figure 2 、 Figure 3 and Figure 4 shown, the pushing structure 42 includes a control groove 421, a horizontal support plate 422, a plurality of guide rods 423 and a plurality of springs 424.

[0047] Among them, the control groove 421 is opened on the movable seat 2, the horizontal support plate 422 is arranged in the control groove 421, one end of the horizontal support plate 422 extends outside the control groove 421, the top surface of the horizontal support plate 422 is connected to the bottom end of the baffle 41, a plurality of guide rods 423 are arranged in parallel in the control groove 421 and penetrate through the horizontal support plate 422, and a plurality of springs 424 are respectively sleeved on the plurality of guide rods 423 and are located at the bottom of the horizontal support plate 422.

[0048] It can be understood that the guide rods 423 are arranged in the control groove 421 and penetrate through the horizontal support plate 422 at the same time, which can ensure the stable vertical lifting movement of the horizontal support plate 422 in the control groove 421. The springs 424 are located at the bottom of the horizontal support plate 422, and the horizontal support plate 422 is pushed by the reaction force of the springs 424, that is, the baffle 41 is always pushed in the clamping groove to restrict the cart 3.

[0049] One end of the horizontal support plate 422 extends to the outside of the control groove 421, facilitating directly controlling the descent of the horizontal support plate 422 from the outside, driving the baffle 41 to descend, releasing the restriction on the trolley 3, and facilitating the replacement of the trolley 3.

[0050] Specifically, when relevant staff need to take out the palletized trolley 3 and replace it, they step on the horizontal support plate 422 through the outlet 12. The horizontal support plate 422 is stressed and descends, and the baffle 41 follows and descends, releasing the restriction on the trolley 3. Then, the trolley 3 is pushed out through the grip. After sending the new trolley 3 onto the movable seat 2, the stepped-on horizontal support plate 422 is released. Affected by the reaction force of the spring 424, the baffle 41 is pushed into the engaging groove to restrict the trolley 3.

[0051] In an embodiment of the present utility model, as Figure 2 and Figure 3 shown, the lifting mechanism 6 includes a connecting block 61, a lead screw 62, and a second driver 63.

[0052] Among them, the connecting block 61 is arranged at one end of the movable seat 2. The lead screw 62 is arranged on the connecting block 61 and is threadedly connected to the connecting block 61. The bottom end of the lead screw 62 is rotatably connected to the bottom surface of the housing 1, and the second driver 63 is arranged at the top end of the lead screw 62, and the second driver 63 is connected to the inner wall of the housing 1.

[0053] It should be noted that the second driver 63 can be a motor for controlling the rotation of the lead screw 62.

[0054] It can be understood that the bottom of the lead screw 62 is rotatably connected to the housing 1 and is threadedly connected to the connecting block 61 at the same time. The connecting block 61 is connected to the movable seat 2. When the lead screw 62 rotates, the connecting block 61 is restricted by the movable seat 2 and cannot rotate, and can only move up and down, thereby realizing the up and down control of the trolley 3. The second driver 63 directly controls the rotation of the lead screw 62.

[0055] Specifically, when relevant staff need the trolley 3 to descend or rise, they start the second driver 63 to control the rotation of the lead screw 62, and the lead screw 62 drives the connecting block 61 to drive the movable seat 2 and the trolley 3 to perform lifting adjustment.

[0056] In summary, for the plywood palletizing device in the embodiment of the present utility model, during the plywood palletizing process, the plywood will not fall and break due to the height difference, ensuring the quality of the plywood. At the same time, the palletized plywood is more convenient to move and transfer.
