Description

Technical Field

[0001] This utility model relates to the field of wood product recycling technology, specifically an automatic sorting device for plywood scraps. Background Technology

[0002] Plywood is a sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets, and then gluing them together with adhesives. It typically uses an odd number of veneer layers, with the grain direction of adjacent veneers perpendicular to each other. During plywood production, to ensure the dimensions and flatness of the boards, the raw materials need to be cut into specified sizes. This process generates a lot of scrap material. If this waste is not disposed of promptly, it not only occupies a lot of space but also pollutes the environment.

[0003] However, plywood scraps are often of very high quality because they are made of multiple layers of wood panels, which are strong, wear-resistant, corrosion-resistant, and have good moisture resistance. Therefore, recycling and reprocessing are common methods of disposal. Thus, the disposal of plywood scraps is an important task, which can not only reduce space occupation but also bring certain economic benefits to enterprises.

[0004] When plywood is processed according to size, scraps of the same type are usually piled together for sorting. Plywood manufacturing plants need to produce a large number of boards every day, so scraps need to be sorted in a timely manner. However, the scraps cut from the edges are often irregular in shape and vary in size, so they can only be identified manually. At the same time, the scrap piles are mixed with a large amount of sawdust generated during the cutting process, causing some boards to be buried, which brings great inconvenience to the sorting personnel. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an automatic sorting device for plywood scraps, which solves the problems mentioned in the background.

[0006] This utility model provides the following technical solution: an automatic sorting device for plywood scraps, comprising: a sorting rack set in the sorting area, and a sorting sieve oscillating back and forth on the sorting rack;

[0007] A conveying mechanism is provided in front of the swinging part of the sorting screen, and a transverse transmission mechanism is provided between the sorting screen and the conveying mechanism. The transmission mechanism is located directly below the opening in front of the sorting screen, and a steering mechanism is installed on the sorting screen.

[0008] A pushing mechanism for ejecting broken materials is provided below the sorting screen, and a driving mechanism is provided behind the pushing mechanism, which is located behind the sorting frame and the sorting screen.

A screen ring is rotatably arranged inside the force-bearing ring through the slide rail, and a slide ring that cooperates with the slide rail is provided on the outer peripheral wall of the screen ring.

[0010] Preferably, the screen ring is provided with a screening frame for screening wood chips and scraps, and multiple sets of surrounding frames are provided at intervals along the edge of the top of the screen ring. The top of the surrounding frames forms an arc-shaped enclosure on the screen ring by an installed arc rod.

[0011] Preferably, a counterweight is provided at one end of the force ring on which the steering mechanism is installed.

[0012] Preferably, the steering mechanism includes a shaft frame mounted on a sorting screen, a worm gear rotatably mounted on the shaft frame, an external toothed ring meshing with the outer edge of the worm gear on the sorting screen, and a shaft core at one end of the worm gear passing through the shaft frame and mounted on the shaft frame with a first motor.

[0013] Preferably, a first ring is provided below the opening of the sorting screen, and a second ring is provided on the pushing mechanism. The first ring and the second ring are connected by a pull rope.

[0014] Preferably, the pushing mechanism includes a pusher plate disposed below the sorting screen, and the upper half of the pusher plate is curved. A reinforcing frame is disposed on one side of the pusher plate, and a positioning rod for interlocking and limiting the drive mechanism is disposed on the other side of the pusher plate. An inner threaded sleeve is integrally disposed at the center of the pusher plate, and an arc groove is formed on the pusher plate surrounding the upper half of the inner threaded sleeve. Rollers are disposed at the bottom of the reinforcing frame.

[0015] Preferably, the driving mechanism includes a frame disposed behind the sorting screen, the frame having a sliding hole for the material pushing mechanism to pass through, a lead screw rotatably disposed in the middle of the frame, the material pushing mechanism having a structural thread sleeved on the lead screw, a dust cover semi-enclosed above the lead screw, the dust cover passing through the material pushing mechanism and mounted on the frame, and a second motor mounted on the frame being disposed at one end of the lead screw passing through the frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This automatic plywood scrap sorting device uses a conveying mechanism to transport stacked plywood scraps into a sorting screen. As the scraps slide to the rear of the sorting screen, non-reproducible wood materials such as wood chips and sawdust are separated and fall off. Then, a drive mechanism controls a pushing mechanism to push out the wood chips and sawdust, simultaneously tilting the sorting screen forward. The sorted wood is then poured onto a conveying mechanism, completing the sorting of scraps. This eliminates the need for manual sorting and has the ability to sort most scraps, improving the automation of plywood scrap recycling.

[0018] 2. This automatic sorting device for plywood scraps uses a steering mechanism on the sorting screen to enable it to rotate left and right. When the sorting screen is used to sort plywood scraps, it rotates back and forth, increasing the sliding speed of the scraps falling on it. At the same time, when there are long and thin pieces of wood that cannot be reused, it can provide a swinging force to these pieces, allowing them to be thrown out from the edge of the sorting screen, thereby improving the sorting effect.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 An automatic sorting device for plywood scrap includes: a sorting rack 1 set in the sorting area, and a sorting screen 2 that is oscillating back and forth on the sorting rack 1;

[0029] A conveying mechanism 4 is provided in front of the swinging part of the sorting screen 2, and a transverse transmission mechanism 5 is provided between the sorting screen 2 and the conveying mechanism 4. The transmission mechanism 5 is located directly below the opening in front of the sorting screen 2. A steering mechanism 3 is installed on the sorting screen 2.

[0030] Below the sorting screen 2 is a pushing mechanism 7 for pushing out broken materials. Behind the pushing mechanism 7 is a driving mechanism 6, which is located behind the sorting frame 1 and the sorting screen 2.

[0031] The sorting screen 2 includes a force-bearing ring 21 arranged in a ring shape on the sorting frame 1. A swing shaft 22 that rotates with the sorting frame 1 is integrally arranged on the outer edge of the force-bearing ring 21. A slide rail 25 is provided on the inner wall of the force-bearing ring 21. A screen ring 23 is rotatably arranged inside the force-bearing ring 21 through the slide rail 25. A slide ring 24 that cooperates with the slide rail 25 is provided on the outer peripheral wall of the screen ring 23.

[0032] The screen ring 23 is equipped with a screening frame 26 for screening wood chips and scraps. Multiple sets of surrounding frames 27 are spaced along the edge of the top of the screen ring 23. The top of the surrounding frames 27 forms an arc-shaped enclosure on the screen ring 23 through the installed arc rods 28.

[0033] Among them, the force ring 21 is equipped with a counterweight at one end where the steering mechanism 3 is installed.

[0034] That is, after the accumulated residual material is transported to the sorting screen 2 by the conveying mechanism 4, the residual material will slide directly to the rear of the sorting screen 2 due to the influence of the counterweight block at the rear end of the force ring 21. During the sliding process, all small pieces and wood chips will be screened out through the gaps on the sorting screen 2.

[0035] It should be noted that rubber pads are provided on the outer shells on both sides of the conveying mechanism 4 near the top, for overlapping at the front opening of the sorting screen 2. Without affecting the operation of the conveying mechanism 4, the rubber pads limit the front of the sorting screen 2, so that the tilt angle of the sorting screen 2 to the rear is controlled within a certain range. At the same time, it ensures that the front of the sorting screen 2 is stably positioned at the docking point with the top of the conveying mechanism 4.

[0036] The steering mechanism 3 includes a shaft frame 31 mounted on the sorting screen 2, a worm gear 32 rotatably mounted on the shaft frame 31, an external toothed ring 34 meshing with the outer edge of the worm gear 32 on the sorting screen 2, and a shaft core at one end of the worm gear 32 passing through the shaft frame 31 and a first motor 33 mounted on the shaft frame 31.

[0037] That is, when sorting the plywood scraps using the sorting screen 2, the sorting screen 2 rotates back and forth by the steering mechanism 3, providing a swinging force to some slender and unreusable wood, thereby improving the sorting effect of the sorting screen 2.

[0038] The sorting screen 2 has a first ring buckle 8 located below the opening, and the pushing mechanism 7 has a second ring buckle 9. The first ring buckle 8 and the second ring buckle 9 are connected by a pull rope 10.

[0039] The pushing mechanism 7 includes a pusher plate 71 located below the sorting screen 2. The upper half of the pusher plate 71 is curved. A reinforcing frame 73 is provided on one side of the pusher plate 71, and a positioning rod 72 for interlocking and limiting the drive mechanism 6 is provided on the other side of the pusher plate 71. An inner threaded sleeve 75 is integrally provided at the center of the pusher plate 71, and an arc groove 76 is provided on the pusher plate 71 surrounding the upper half of the inner threaded sleeve 75. A roller 74 is provided at the bottom of the reinforcing frame 73.

[0040] The drive mechanism 6 includes a frame 61 located behind the sorting screen 2. The frame 61 has a sliding hole 62 for the pusher mechanism 7 to pass through. A lead screw 63 is rotatably mounted in the middle of the frame 61. The pusher mechanism 7 is threaded onto the lead screw 63. A dust cover 65 is semi-enclosed above the lead screw 63. The dust cover 65 passes through the pusher mechanism 7 and is mounted on the frame 61. One end of the lead screw 63 passes through the frame 61 and is mounted on the frame 61 with a second motor 64.

[0041] That is, such as Figure 6 , Figure 7 As shown, the lead screw 63 is threaded in the inner thread sleeve 75. The movement position of the pushing mechanism 7 is controlled by the start of the second motor 64. While pushing out the wood that has been screened, the traction rope 10 can also be used to pull the sorting screen 2 to pour the screened wood onto the conveying mechanism 5, thus achieving the effect of linkage operation.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
