Utility model content

DETAILED DESCRIPTION

[0021] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0022] The embodiment of the present application discloses a plywood hot-pressing device with an automatic stacking mechanism. Referring to Figure 1 , Figure 2 and Figure 3The plywood hot pressing device with the automatic stacking mechanism comprises a hot pressing device 1 body and a stacking table 2 arranged at one side of the hot pressing device 1 body, a mounting rack 3 is arranged at the side of the stacking table 2 away from the hot pressing device 1 body, a feeding table 4 and a conveying roller 41 are arranged between the mounting rack 3 and the hot pressing device 1 body to convey materials to the stacking table 2, a baffle 21 is fixed to the side of the stacking table 2 away from the feeding table 4, a supporting table 5 is arranged at the opposite side of the hot pressing device 1 and the mounting rack 3, a supporting plate 6 is fixed below the supporting table 5 and located between the mounting rack 3 and the hot pressing device 1 body, and the stacking table 2 is arranged on the supporting plate 6 in a lifting mode.

[0023] A control assembly is arranged between the stacking table 2 and the supporting plate 6 to lower the stacking table 2 onto the supporting table 5 when the stacking table 2 is stacked with corresponding materials, a pushing assembly is arranged on the mounting rack 3 to push the materials stacked on the stacking table 2 to the lower pressing plate of the hot pressing device 1, and the pushing assembly is in control connection with the control assembly.

[0024] In the plywood production, the materials to be hot pressed are placed on the feeding table 4, and the conveying roller 41 is started to convey the materials to the stacking table 2. The baffle 21 on the stacking table 2 can guide the materials to ensure that the materials are correctly moved to the stacking table 2 during the conveying process and help to position the materials to keep the materials neat during stacking. At the same time, under the action of the control assembly, the stacking table 2 is gradually lowered to stack the materials layer by layer on the stacking table 2. When the stacking table 2 is stacked with corresponding materials, the stacking table 2 is lowered onto the supporting table 5. At this time, the pushing assembly is activated to push the stacked materials to the lower pressing plate of the hot pressing device 1, effectively improving the problem of manual stacking of plywood in the plywood production, which is time-consuming and laborious and also leads to low production efficiency of the plywood.

[0025] Specifically referring to Figure 1 , Figure 2 and Figure 3 , the control assembly comprises a plurality of positioning columns 22 fixed to the lower end surface of the stacking table 2, a plurality of positioning holes 61 corresponding to the plurality of positioning columns 22 are arranged on the supporting plate 6, the positioning columns 22 extend into the positioning holes 61, and a plurality of elastic members are arranged between the stacking table 2 and the supporting plate 6; when the stacking table 2 is lowered onto the supporting table 5, the elastic members are in a deformed state.

[0026] Such an arrangement not only ensures the stability of the stacking table 2 during the stacking of the materials, but also provides a buffering effect to reduce the impact of the materials on the stacking table 2, and can also adapt to the stacking of materials of different heights to improve the flexibility and reliability of the entire hot pressing device 1.

[0027] And referring to Figure 1The elastic member is a spring 23, and the plurality of springs 23 are in one-to-one correspondence with the plurality of positioning columns 22 and are sleeved outside the positioning columns 22. Such a layout allows the spring 23 to provide the necessary elastic force when the positioning column 22 rises and falls, without affecting the positioning function of the positioning column 22, further improving the stability of the material stacking table 2 during the material stacking process; and since the spring 23 is independent, when a certain spring 23 fails, it can be replaced individually, and the maintenance is relatively simple.

[0028] Further, with reference to Figure 1 and Figure 2 , the pushing assembly includes a pneumatic cylinder 31 fixed on the mounting frame 3 and arranged along the width direction of the material conveying table 4, and a pushing plate 32 is fixed on the piston rod of the pneumatic cylinder 31.

[0029] The piston rod of the pneumatic cylinder 31 is provided with a limiting plate 33 close to one side of the pneumatic cylinder 31, and the piston rod horizontally penetrates through the limiting plate 33 and is fixed thereto.

[0030] And a plurality of supporting rods 34 are fixed between the pushing plate 32 and the limiting plate 33.

[0031] In this way, when the pneumatic cylinder 31 drives the pushing plate 32 to push the stacked materials to the lower pressing plate of the hot pressing device 1, since the supporting rods 34 are fixed between the pushing plate 32 and the limiting plate 33, structural support can be provided, the stability of the pushing plate 32 is enhanced, deformation or vibration of the pushing plate 32 when pushing the materials is avoided, and at the same time, the partial spring 23 is also avoided from being deformed when pushing the materials and the piston rod is retracted, so as to affect the smoothness of the whole system.

[0032] In addition, with reference to Figure 1 , the pneumatic cylinder 31 is sleeved with a fixed sleeve 311 fixed on the mounting frame 3, and the fixed sleeve 311 is designed to provide a firm support structure for the pneumatic cylinder 31, which helps to improve the stability and reliability of the whole pushing assembly.

[0033] The implementation principle of the plywood hot pressing device 1 with the automatic plate stacking mechanism according to the embodiment of the present application is as follows:

[0034] In the production of plywood, the plywood material to be hot-pressed is placed on the conveying table 4, and the transmission roller 41 is started to convey the material to the stacking table 2. The baffle 21 on the stacking table 2 can help guide the material and ensure that the material can be correctly moved to the stacking table 2 during conveying, and help position the material to keep the material neat when stacking. At the same time, under the action of the control assembly, the stacking table 2 gradually descends so that the material is stacked layer by layer on the stacking table 2. When the stacking table 2 is stacked with corresponding material, the stacking table 2 is lowered to the support 5. At this time, the pushing assembly is activated, and the air cylinder 31 drives the pushing plate 32 to push the stacked material to the lower pressing plate of the hot-pressing device 1, effectively improving the problem of manual stacking of plywood during plywood production, which is time-consuming and laborious and also leads to low plywood production efficiency.
