[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0029] As Figures 1 to 4 shown, this embodiment proposes a multi-layer hot pressing feeding device for plywood, including

[0030] a conveying frame 1, and a conveying roller 2 is arranged on the conveying frame 1;

[0031] a length adjustment component 3, and the length adjustment component 3 is arranged on the conveying frame 1;

[0032] The stable feeding assembly 4 is arranged on one side of the upper end surface of the conveying rack 1;

[0033] The length adjustment assembly 3 includes a limit frame 3-1 which is arranged on the bottom surface of the conveying rack 1. A telescopic cylinder 3-2 is arranged on the lower end surface of the limit frame 3-1. The output end of the telescopic cylinder 3-2 passes through the limit frame 3-1. The output end of the telescopic cylinder 3-2 is connected with a limit plate 3-3. A clamping plate 3-4 is arranged on the side wall of the limit plate 3-3. A limit slideway 3-5 is arranged on the side surface of the limit frame 3-1. The opposite sides of the clamping plate 3-4 are embedded in the limit slideway 3-5. A portal frame 3-6 is arranged on the upper end surface of the limit frame 3-1. A lifting cylinder 3-7 is arranged on the portal frame 3-6. The output end of the lifting cylinder 3-7 is provided with a cutting motor 3-8. The output end of the cutting motor 3-8 is provided with a cutting cutter head 3-9.

[0034] In this embodiment, the plywood is placed on the conveying rack 1, and the conveying rollers 2 driven by the motor rotate, so as to realize the translational movement of the plywood. During the movement of the plywood, the telescopic cylinder 3-2 rises upward accordingly, thereby driving the limit plate 3-3 and the clamping plate 3-4 to move upward. At this time, the limit plate 3-3 is attached to the plywood. The lifting cylinder 3-7 drives the cutting motor 3-8 to descend, and the cutting motor 3-8 drives the cutting cutter head 3-9 to rotate. The cutting cutter head 3-9 cuts the plywood. During the cutting process, the clamping plate 3-4 can be used for limiting to avoid the problem that one side of the plywood is stressed while the other side is lifted.

[0035] Specifically, the number of the conveying rollers 2 is several, and multiple conveying rollers 2 are all driven by the motor. The rotation speeds and rotation directions of multiple conveying rollers 2 are the same.

[0036] Furthermore, a support plate 4-1 is arranged on the upper end surface of the conveying rack 1. A pressing plate 4-2 is pin-connected inside the support plate 4-1. A walking wheel 4-3 is arranged on the side wall of the pressing plate 4-2. An arc track 4-4 is opened on the inner surface of the support plate 4-1. A positioning shaft 4-5 is arranged on the outer side wall of the pressing plate 4-2, and the positioning shaft 4-5 is embedded in the arc track 4-4.

[0037] In this embodiment, the pressing plate 4-2 on the support plate 4-1 is limited in the arc track 4-4 through the positioning shaft 4-5, so that when the walking wheel 4-3 on the pressing plate 4-2 contacts the plywood, the pressing plate 4-2 has a swinging effect, and the walking wheel 4-3 on the pressing plate 4-2 is used for the stable effect during the progress of the plywood.

[0038] Furthermore, a counterweight 5 is arranged at the edge of the lower end surface of the pressing plate 4-2. Support feet 6 are arranged at the lower end surface of the transmission shaft, and the number of the support feet 6 is 4-6. The support feet 6 are evenly distributed on the lower end surface of the conveying rack 1.

[0039] In this embodiment, the counterweight 5 can make the walking wheel 4-3 always fit the plywood.

[0040] Further, the limiting plate 3-3 and the clamping plate 3-4 are located at the gap of the conveying roller 2. A relief groove 7 is formed on the upper end surface of the conveying frame 1. The bottom surface of the relief groove 7 is lower than the height of the conveying roller 2. The lifting cylinder 3-7 and the limiting frame 3-1 are connected by screwing bolts, and the lifting cylinder 3-7 and the gantry frame 3-6 are connected by screwing bolts.

[0041] In this embodiment, the relief groove 7 is used to keep the plywood on the conveying roller 2 during the movement. The height of the relief groove 7 is always lower than the height of the conveying roller 2, so that the plywood keeps moving on the conveying roller 2.

[0042] Further, an anti-slip rubber pad 8 is sleeved on the walking wheel 4-3. A conveying groove 9 is formed on the conveying frame 1. The conveying roller 2 is arranged in the conveying groove 9. The diameter of the cutting cutter head 3-9 matches the width of the conveying groove 9.

[0043] In this embodiment, the anti-slip rubber pad 8 is used to make the movement of the walking wheel 4-3 on the plywood more stable.

[0044] When feeding the plywood into the machine, place the plywood on the conveying frame 1. The conveying roller 2 driven by the motor rotates, so as to realize the translational movement of the plywood. During the movement of the plywood, the telescopic cylinder 3-2 rises upward accordingly, driving the limiting plate 3-3 and the clamping plate 3-4 to move upward. At this time, the limiting plate 3-3 fits the plywood. The lifting cylinder 3-7 drives the cutting motor 3-8 to descend, and the cutting motor 3-8 drives the cutting cutter head 3-9 to rotate. The cutting cutter head 3-9 cuts the plywood. During the cutting process, the clamping plate 3-4 can be used for limiting to avoid the problem that one side of the plywood is stressed while the other side is lifted. The walking wheel 4-3 on the pressing plate 4-2 is used to ensure the stability of the plywood during the movement and prevent the plywood from jumping.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
