Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a wood scrap recycling device with a screening function. Background Technique

[0002] Scrap is named according to its source. It comes from the corners of wood and is usually a by-product generated during the production of wooden furniture. During the woodworking cutting process, scrap is usually accompanied by it. The scrap needs to be separated, screened, processed and treated from wood chips and sawdust before it can be reused.

[0003] In the prior art, the wood scrap recycling device includes a box body. An inlet is opened at the top of the box body. A stirring and separating device is arranged on the upper layer inside the box body. A vibrating mechanism for a sieve plate is fixed at the bottom of the inner cavity of the box body. For example, the patent named "A Scrap Screening Device for Wood Processing" with the patent number "201810677957.8" discloses a scrap screening device for wood processing.

[0004] However, due to the different shapes and edges of the wood scraps generated during the cutting of different furniture, the sizes of the recyclable scraps are also different. The sizes of the sieve holes of the existing sieve plates are fixed, which cannot meet the screening work of scraps during the production of diverse furniture. And during the screening process, some special-shaped scraps will hook or block the sieve holes, thereby clogging the sieve mesh and affecting the smooth screening work of the wood scraps.

[0017] (III) Beneficial effects

[0018] The present utility model provides a wood scrap recycling device with a screening function. It has the following

[0019] Beneficial effects:

[0020] 1. In the utility model, the hole-adjusting motor can be used to make the special-shaped screen plate slide horizontally on the lower side of the fixed screen plate under the action of the screw nut mechanism. Since the special-shaped screen holes are set as conical special-shaped holes with inner diameter width gradually decreasing from left to right, the connection area between the special-shaped screen holes and the fixed screen holes will change during the sliding process of the special-shaped screen holes, thereby changing the size of the screen holes for screening wood scraps to meet the different sizes of recyclable wood scraps generated during the cutting process of different furniture.

[0021] 2. In the utility model, the inner wall of the special-shaped screen hole is set as a shearing slope inclined from top to bottom and outward. When the special-shaped screen plate and the fixed screen plate are fitted with each other, the shearing slope forms a shearing opening with the fixed screen hole of the fixed screen plate. When the special-shaped scraps will hook or get stuck in the main screen hole, some edges and corners of the wood scraps will be inserted into the fixed screen hole, thus forming a situation of hooking the fixed screen plate. The shearing cylinder reciprocates and expands and contracts, which can reciprocate the shearing of the special-shaped screen hole and the fixed screen hole, and cut off the edges and corners of the scraps stuck on the fixed screen hole, which can ensure that the wood scraps can slide out of the screening opening smoothly under vibration.

[0022] 3. In addition, two driving devices, a hole-adjusting motor and a shearing cylinder, are respectively provided. The hole-adjusting motor can independently control the size of the sieve holes of the required wood scraps to be fixed, and the shearing cylinder can independently control the shearing. The two do not interfere with each other, ensuring that there is no conflict in the screening and shearing processes. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Working principle: In the working process of the wood scrap recycling device with screening function in the present utility model, the mixed wood scraps are put into the box body 1 from the feed port. The wood scraps enter the guide separation cavity 4. Under the action of the separation motor, the stirring paddle stirs the wood scraps, so that the sawdust attached to the wood scraps can be separated from the wood scraps. Then, it falls on the fixed sieve plate 52 through the separation port. The installation shell 51 vibrates up and down driven by the cam 15 mechanism. During the vibration, the smaller wood chips and sawdust fall along the communication part of the fixed sieve holes 6 and the special-shaped sieve holes 7 to the bottom of the box body 1 and slide out from the slag outlet 3 at the bottom of the box body 1;

[0032] When it is necessary to change the size of the recycled wood scraps, start the hole-adjusting motor 8. Under the action of the lead screw nut mechanism, the special-shaped sieve holes 7 slide, changing the communication area between the special-shaped sieve holes 7 and the fixed sieve holes 6, so as to meet the requirements of different sizes of recycled wood scraps;

[0033] In addition, when the edges and corners of the wood scraps are inserted into the fixed sieve holes 6 and hooked or stuck in the fixed sieve holes 6, start the shearing cylinder 12. The shearing cylinder 12 pushes the shearing inclined surface 11 at the bottom of the fixed sieve plate 52 to cut off the edges and corners of the shearing inclined surface 11 inserted into the fixed sieve holes 6, preventing the wood scraps from jamming the fixed sieve plate 52, so that the recyclable wood scraps slide out from the screening port along the inclined fixed sieve plate 52 under the vibration action.
