Otherwise, it is actually a mixture of shavings of countless materials, and the quality of the final molded board cannot be guaranteed at all. Therefore, if the wood shavings are pre-treated by classification, shavings of similar density are classified into one category, and then crushed to similar specifications, they can be used as a good raw material.

DETAILED DESCRIPTION

[0023] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0024] See also Figure 1 to Figure 2 The utility model provides a wood shavings screening device, including a material frame 100, a vibration plate 200 and a vibration mechanism 300.

[0025] Specifically, the top of the material frame 100 is open, and the side wall of one side of the material frame 100 is a sliding plate 110, which can slide up and down. The vibration plate 200 divides the material frame 100 into an upper chamber and a lower chamber that are not connected to each other, and the vibration plate 200 can move up and down and left and right in the material frame 100. The vibration mechanism 300 is arranged in the lower chamber and connected to the vibration plate 200, and is used to drive the vibration plate 200 to vibrate up and down.

[0026] When in use, the shavings are first added from the material frame 100, and then the vibration mechanism 300 is started. The vibration mechanism 300 drives the vibration plate 200 to vibrate continuously. During the vibration process, the shavings will be automatically layered under the vibration. When the lengths are similar, the shavings with high density and heavy weight are located at the bottom, followed by the next layer, and the top layer is the lowest density and lightest weight. After stopping the vibration, the sliding plate 110 is slid down to form a discharge port, and the shavings can be moved from the discharge port layer by layer from top to bottom.

[0027] By adopting the above device, the wood shavings can be quickly and conveniently classified, thereby facilitating subsequent processing needs.

[0028] In addition, during specific implementation, the material frame 100 can be set to be transparent to facilitate the penetration of the internal wood shavings layering.

[0029] In this embodiment, the vibration plate 200 includes a plate body 210 and a flexible buffer pad 220. The flexible buffer pad 220 wraps the side wall of the plate body 210 along the periphery of the plate body 210, and the plate body 210 is in sealing contact with the material frame 100 through the flexible buffer pad 220. The setting of the buffer pad can not only play a sealing role, but also facilitate the vibration of the vibration plate 200 up, down, left and right.

[0030] In this embodiment, the vibration mechanism 300 includes a support plate 310, a vibration block 320 and a horizontal motion driving source 330. The support plate 310 is fixedly arranged below the vibration plate 200. The vibration block 320 can be laterally slidably clamped on the support plate 310. The horizontal motion driving source 330 is connected to the vibration block 320 and is used to drive the vibration plate 200 to slide laterally on the support plate 310. A plurality of convex strips 230 are arranged at intervals on the bottom surface of the vibration plate 200. The plurality of convex strips 230 are arranged at intervals along the movement direction of the vibration block 320. The distance between two connected convex strips 230 is greater than the width of the vibration block 320, and the two connected convex strips 230 are smoothly connected.

[0031] When the horizontal motion driving source 330 drives the vibration block 320 to move horizontally, under the action of the convex strips 230, the vibration plate 200 can be driven to shake up and down and left and right to achieve the purpose of vibration.

[0032] In this embodiment, the horizontal motion driving source 330 includes a rotary power source 331, a first crank 332, a second crank 333, a third crank 334 and a swing rod 335. The first crank 332 is connected to the rotary power source 331 in rotation, the first crank 332 and the second crank 333 are hinged to the first crank 332, the end of the second crank 333 is hinged to the third crank 334, and the end of the third crank 334 is fixed. That is, the rotary power source 331, the first crank 332, the second crank 333 and the third crank 334 form a four-bar linkage. One end of the swing rod 335 is hinged to the hinge point of the second crank 333 and the third crank 334, and the other end of the swing rod 335 is hinged to the vibration block 320. When the rotary power source 331 rotates, the swing rod 335 can be driven to move through the first crank 332, the second crank 333 and the third crank 334.

[0033] During use, when the rotating power source 331 is started, the vibration block 320 can be driven to move horizontally and non-transportingly to the left and right through the first crank 332, the second crank 333, the third crank 334 and the rocker 335, thereby further improving the vibration effect.

[0034] It should be noted that, in other embodiments, the horizontal motion driving source 330 may also be other forms of mechanisms, such as a chain mechanism, or a direct horizontal telescopic mechanism.

[0035] As a preferred embodiment, the device further comprises a pushing structure 400 which is movably arranged in the material frame 100 and opposite to the sliding plate 110 for pushing out the topmost layer of shavings from the notch of the sliding plate 110 which slides downward.

[0036] In this embodiment, the pushing structure 400 includes a pushing plate 410 and a pushing source 420. The pushing plate 410 is vertically arranged in the material frame 100, and the pushing plate 410 is arranged opposite to the sliding plate 110. The pushing plate 410 can move laterally toward the sliding plate 110. The pushing source 420 is connected to the pushing plate 410, and drives the pushing plate 410 to move laterally toward the sliding plate 110.

[0037] Specifically, the driving source 420 includes a guide rail 421, a lifting driving source 422, a mounting plate 423 and a telescopic power source 424. The guide rail 421 is vertically arranged on the side wall opposite to the sliding plate 110. The mounting plate 423 is arranged on the guide rail 421 and slides up and down along the guide rail 421. The lifting driving source 422 is connected to the mounting plate 423 to drive the mounting plate 423 to move up and down. The telescopic power source 424 is installed on the mounting plate 423. The telescopic shaft of the telescopic power source 424 is connected to the push plate 410. The telescopic power source 424 can push the push plate 410 to move laterally toward the sliding plate 110.

[0038] When the shavings need to be pushed out layer by layer from top to bottom, the sliding plate 110 is first driven downward until the upper end of the sliding plate 110 is flush with the bottom surface of the uppermost layer of shavings, and then the mounting plate 423 is driven up and down by the lifting drive source 422 until the lower end of the push plate 410 is flush with the upper end of the sliding plate 110, and then the telescopic power source 424 is started to drive the push plate 410 to push in the direction of the sliding plate 110, so that the shavings can be pushed out from the discharge port formed by sliding under the sliding plate 110.

[0039] It should be noted that in this embodiment, both the lifting drive source 422 and the telescopic power source 424 can be telescopic motors commonly used in the prior art.

[0040] The use of the above-mentioned wood shavings screening device:

[0041] When in use, the shavings are first added from the material frame 100, and then the rotating power source 331 is started to drive the vibration plate 200 to vibrate continuously. During the vibration process, the shavings will automatically be layered under the vibration. When the length is similar, the shavings with high density and heavy mass are at the bottom, followed by the next, and the top layer is the lowest density and lightest mass.

[0042] After the vibration stops, the sliding plate 110 is slid down to form a discharge port, and then the push plate 410 is moved to a suitable height, and the shavings can be pushed out of the discharge port layer by layer from top to bottom.

[0043] By adopting the above device, the wood shavings can be quickly and conveniently classified, thereby facilitating subsequent processing needs.
