Description

Technical Field

[0001] This utility model relates to the field of wood scrap processing technology, specifically a screening machine for wood scrap processing. Background Technology

[0002] Screening is a process that uses a sieve to allow fine particles smaller than the sieve openings to pass through the sieve surface, while coarse particles larger than the sieve openings remain on the sieve surface, thus completing the separation of coarse and fine materials. This separation process can be regarded as consisting of two stages: material stratification and fine particle screening.

[0003] Currently used screening machines for processing wood scraps consist of a screening frame with a screening plate installed on the inner wall. The frame is equipped with springs and a vibration motor. When the vibration motor starts, it generates a vibration force, which, along with the spring's bounce, enables the wood scraps to be screened vertically. However, when the wood scraps are poured onto the screening plate and during the screening process, they are not evenly distributed, causing them to accumulate in one place. This excessive accumulation hinders the normal screening progress. To improve the screening efficiency of wood scraps, a new screening machine for processing wood scraps has been proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screening machine for processing wood scraps, which has the advantage of accelerating the screening efficiency of wood scraps.

[0005] To achieve the above-mentioned goal of accelerating the screening efficiency of wood scraps, this utility model provides the following technical solution: a screening machine for processing wood scraps, including a base carriage and a screening box, a screening plate is fixedly installed on the inner side wall of the screening box, a dual-shaft motor is fixedly installed on the bottom of the screening box, a rotating shaft is fixedly installed on the output shaft of the dual-shaft motor, and mounting blocks are fixedly installed on the bottom of the screening box and near the front and rear walls of the screening box. A reciprocating pushing component for accelerating the screening efficiency of wood scraps is provided on the screening box, the rotating shaft and the mounting blocks.

[0006] The reciprocating drive assembly includes a disc, a swing rod, a drive hole, a movable seat, a drive column, and a lever. The disc is fixedly mounted on the end of the rotating shaft. The swing rod is rotatably connected to the mounting block. The drive hole is opened on the swing rod, and each swing rod has two drive holes. The movable seat is slidably connected to the top wall of the screening box. The drive column is fixedly connected to the disc and the movable seat. The drive column is movably connected to the inner wall of the drive hole. The lever is fixedly connected to the bottom of the movable seat.

[0007] Furthermore, the screening plate has screening holes, the rotating shaft is rotatably connected to the mounting block and passes through the mounting block, the driving column extends into the inner wall of the driving hole, and the actuating rod is cylindrical in shape.

[0008] Furthermore, a locking pin is fixedly installed on the mounting block and rotatably connected to the swing arm; a stop block corresponding to the swing arm is fixedly installed on the drive column; and a slide rail that is slidably connected to the movable seat is fixedly installed on the top of the screening box. The side of the slide rail is dovetail-shaped.

[0009] Furthermore, a vertical rod is fixedly installed on the top of the chassis, and connecting blocks are fixedly installed on the front and rear walls of the screening box. The connecting blocks are slidably connected to the outer surface of the vertical rod, and a limiting block corresponding to the connecting block is fixedly connected to the top of the vertical rod.

[0010] Furthermore, a vibration assembly is provided on the base car, the rotating shaft, and the connecting block. The vibration assembly includes an eccentric block and a spring. The eccentric block is fixedly installed on the outer surface of the rotating shaft, and the spring is fixedly installed between the base car and the connecting block on opposite sides. The eccentric block is fan-shaped, and the vertical rod is located inside the spring.

[0011] Furthermore, the side wall of the screening box has two discharge ports, and the inner wall of the discharge ports is fitted with baffles. Bolts threaded into the baffles are inserted into the baffles and connected to the screening box. The top view of the baffles is T-shaped.

[0012] Compared with the prior art, this utility model provides a screening machine for processing wood scraps, which has the following advantages:

[0013] This wood scrap screening machine, through the use of a reciprocating push component, uses a rotating disc to drive a swing rod that swings back and forth along the axis of the locking pin. This causes a movable seat with the drive column to move back and forth along the outer surface of the slide rail, allowing a lever below the movable seat to move back and forth as well. This, in turn, moves the wood scraps on the screening plate, preventing them from gathering in one place and ensuring they are evenly spread on the screening plate. This allows the wood scraps to be screened more quickly, improving the screening efficiency. Moreover, using only a single dual-axis motor, both the movement and vibration screening of the wood scraps can be achieved, making it more energy-efficient and effective.

[0018] 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.

[0019] Please see Figure 1-3 A screening machine for processing wood scraps includes a base car 1 and a screening box 2. A screening plate 3 is fixedly installed on the inner side wall of the screening box 2. Screening holes are opened on the screening plate 3 for screening wood scraps. Large wood scraps are intercepted on the screening plate 3, while small wood scraps pass through the screening holes and fall into the inner bottom wall of the screening box 2. Two discharge ports are opened on the side wall of the screening box 2. Baffles 15 are inserted into the inner wall of the discharge ports to prevent wood scraps from being discharged during the screening process. Baffles 15 abut against the screening plate 3. Bolts 16 threadedly connected to the screening box 2 are inserted through the baffles 15 for installation and removal. After removal, the screened wood scraps can be discharged. The top view of the baffles 15 is T-shaped.

[0020] The bottom of the screening box 2 is fixedly equipped with a dual-axis motor 4, and the output shaft of the dual-axis motor 4 is fixedly equipped with a rotating shaft 5. When the dual-axis motor 4 is started, the rotating shaft 5 rotates, gradually vibrating and screening the wood scraps. The bottom of the screening box 2 and the front and rear walls of the screening box 2 are fixedly equipped with mounting blocks 6. The rotating shaft 5 is rotatably connected to the mounting blocks 6 and the mounting blocks 6 pass through it to support the rotating shaft 5.

[0021] In addition, a vertical rod 11 is fixedly installed on the top of the bottom car 1, and connecting blocks 12 are fixedly installed on the front and rear walls of the screening box 2. The connecting blocks 12 are slidably connected to the outer surface of the vertical rod 11. The connecting blocks 12 can move up and down along the outer surface of the vertical rod 11 to realize the vibration screening of wood scraps. A limiting block 13 corresponding to the connecting block 12 is fixedly connected to the top of the vertical rod 11 to prevent the connecting block 12 from completely detaching from the vertical rod 11, thus playing a limiting role.

[0022] Specifically, a vibration assembly 14 is provided on the base car 1, the rotating shaft 5 and the connecting block 12. The vibration assembly 14 includes an eccentric block 141 and a spring 142. The eccentric block 141 is fixedly installed on the outer surface of the rotating shaft 5. The eccentric block 141 rotates with the rotating shaft 5, generating centrifugal force to obtain excitation force. The spring 142 is fixedly installed between the base car 1 and the connecting block 12 on opposite sides. The excitation force causes the spring 142 to be squeezed during the rotation of the eccentric block 141 and can bounce repeatedly, allowing the screening plate 3 and the screening plate 3 to vibrate up and down to screen wood scraps. The eccentric block 141 is fan-shaped, and the vertical rod 11 is located inside the spring 142.

[0023] Please see Figure 1-3 The screening box 2, the rotating shaft 5, and the mounting block 6 are equipped with a reciprocating push assembly 7 to accelerate the screening efficiency of wood scraps. The reciprocating push assembly 7 includes a disc 71, a swing rod 72, a drive hole 73, a movable seat 74, a drive column 75, and a toggle rod 76. The disc 71 is fixedly installed at the end of the rotating shaft 5 and can rotate with the rotating shaft 5. The swing rod 72 is rotatably connected to the mounting block 6. A locking pin 8 is fixedly installed on the mounting block 6 and is rotatably connected to the swing rod 72. The swing rod 72 can swing around the axis of the locking pin 8. The drive hole 73 is opened on the swing rod 72 and can swing with the swing rod 72. Each swing rod 72 has two drive holes 73.

[0024] Furthermore, the movable seat 74 is slidably connected to the top wall of the screening box 2, and the movable seat 74 moves laterally on the top wall of the screening box 2. The top of the screening box 2 is fixedly installed with a slide rail 10 that is slidably connected to the movable seat 74 for guiding and supporting the movable seat 74. The side of the slide rail 10 is dovetail shaped. The drive column 75 is fixedly connected to the disc 71 and the movable seat 74. The drive column 75 is movably connected to the inner wall of the drive hole 73. The drive column 75, which moves with the disc 71, can push the swing rod 72 with the drive hole 73 back and forth. The top of the swing rod 72 pushes the movable seat 74 connected to the drive column 75 back and forth, so that the movable seat 74 can move laterally back and forth.

[0025] Meanwhile, a stop 9 corresponding to the swing arm 72 is fixedly installed on the drive column 75 to limit the swing arm 72 and prevent the drive column 75 from separating from the swing arm 72. The drive column 75 extends into the inner wall of the drive hole 73. The actuating rod 76 is fixedly connected to the bottom of the movable seat 74 and can move back and forth laterally with the movable seat 74. The reciprocating lateral movement of the actuating rod 76 can move the wood scraps, reduce the accumulation of wood scraps, and make the wood scraps be screened by the screening hole as soon as possible. The actuating rod 76 is cylindrical in shape.

[0026] In this embodiment, wood scraps are poured onto the screening plate 3, and the dual-shaft motor 4 is started. The rotating shaft 5, eccentric block 141, and disc 71 rotate. The rotation of eccentric block 141 generates centrifugal force, which excites the screening box 2, causing it to shake up and down. The spring 142 is compressed and bounces, causing the wood scraps on the screening plate 3 to be vibrated and screened. The movement of the drive column 75 on the disc 71 pushes the swing rod 72 to swing around the axis of the locking nail 8. This causes the top drive column 75, which extends into the drive hole 73, to drive the movable seat 74 to move back and forth laterally along the outer surface of the slide rail 10. The actuating rod 76 is also driven to move back and forth laterally, thereby moving the wood scraps on the screening plate 3 back and forth. This reduces the accumulation of wood scraps in one place and allows the wood scraps to be spread as flat as possible on the screening plate 3, improving the screening efficiency of wood scraps.

[0027] The beneficial effects of the above embodiments are as follows:

[0028] This wood scrap screening machine, through the setting of a reciprocating push component 7, after the reciprocating push component 7 is used, under the rotation of the disc 71, the drive column 75 on the disc 71 drives the swing rod 72 to swing back and forth along the axis of the locking nail 8, causing the movable seat 74 with the drive column 75 to move back and forth along the outer surface of the slide rail 10, so that the actuating rod 76 under the movable seat 74 can move back and forth, thereby agitating the wood scraps on the screening plate 3, avoiding the wood scraps from gathering in one place, and allowing the wood scraps to be evenly spread on the screening plate 3, so that the wood scraps can be screened as quickly as possible, improving the screening efficiency of wood scraps. Moreover, only a dual-shaft motor 4 is used to realize both the agitation of wood scraps and the vibration screening of wood scraps, which is more energy-saving and efficient.

[0029] The dual-axis motor 4 mentioned in the text is electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be elaborated in the text.
