Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a waste treatment device for wood processing. Background Technology

[0002] Wood processing equipment generates a lot of wood waste during the wood processing process. This wood waste can be recycled and reused. The wood waste can be made into chip structures, and then the wood chips can be used to make various products such as wood chipboard, MDF, wood chip coal, and wood chip charcoal, so as to achieve the purpose of waste reuse and effectively save natural resources.

[0003] Existing wood waste is usually processed by shredding equipment. The shredded wood chips are piled up and then transported to the next processing equipment for further processing. However, there are gaps between the chips, which take up transportation space and they are easily blown away by the wind during transportation, which increases the cost of chip transportation. Utility Model Content

[0004] The purpose of this utility model is to provide a waste processing device for wood processing, so as to solve the problem mentioned in the background art that, in order to improve the accuracy of detection, it is generally necessary to measure and compare multiple groups of concrete. Changing the concrete in the measuring bowl requires opening the measuring device and replacing the concrete in the measuring bowl, which is time-consuming and labor-intensive, resulting in low measurement efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste processing device for wood processing, comprising an L-shaped housing, a feeding hopper fixedly provided at the upper end of the L-shaped housing, a discharge channel provided inside the L-shaped housing, and a crushing device, an anti-blocking mechanism, a wood chip pressing mechanism, and a discharge assembly installed on the L-shaped housing. The crushing device includes two crushing rollers that are meshed together and rotatably disposed inside the L-shaped housing via a shaft. The wood chip pressing mechanism includes an electric push rod, which is fixedly installed on the outer surface of the L-shaped housing. The piston rod of the electric push rod extends movably into the discharge channel and is fixedly connected to a pressure plate. The discharge assembly includes a stop block, which and the pressure plate are slidably disposed inside the discharge channel. The stop block is fixedly connected to two guide rods, which movably penetrate the outside of the L-shaped housing and are fixedly connected to a second limiting block. A return spring is fixedly connected between the second limiting block and the L-shaped housing, and the return spring is sleeved and installed on the outer surface of the guide rod.

[0006] Preferably, the discharge channel includes a crushing chamber, a T-shaped chamber and an inclined chamber. Two crushing rollers are rotatably installed in the crushing chamber. A stop block and a pressure plate are slidably installed at the bottom of the T-shaped chamber, and the surfaces of the stop block and the pressure plate are in contact with the inner wall of the bottom of the T-shaped chamber.

[0007] Preferably, the shafts of the crushing rollers are all fixedly connected to gears, and two gears are meshed together. A mounting base is fixedly provided on the L-shaped housing, and a first motor is fixedly installed on the mounting base. The output end of the first motor is driven by a belt mechanism, and the pulley at the upper end of the belt mechanism is driven by the shaft of one crushing roller.

[0008] Preferably, a damping sleeve is fixedly fitted on the outer surface of each guide rod to delay the reset spring from forcing the stop block to reset.

[0009] Preferably, two sliding rods are fixedly provided on the pressure plate. The sliding rods movably pass through the outside of the L-shaped housing and are fixedly connected to a first limiting block. The width of the pressure plate is greater than the vertical cavity width of the T-shaped cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This waste processing device can crush the waste generated from wood processing into chips inside the L-shaped shell through two crushing rollers. The electric push rod forces the pressure plate to move towards the stop block, compressing the chips into a block structure. Furthermore, by utilizing the fact that the reset speed of the stop block is less than that of the pressure plate, the pressed chip blocks can be smoothly discharged. During the pressing process, the pressure plate can prevent chips from entering between the pressure plate and the stop block, achieving the purpose of intermittent pressing. This makes the pressure plate forming structure uniform, reduces the space occupied by the crushed wood chips, and facilitates transportation for subsequent production and processing.

[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] See also Figures 1 to 3This utility model provides a technical solution: a waste processing device for wood processing, including an L-shaped housing 1. A feed hopper 11 is fixedly mounted on the upper end of the L-shaped housing 1. A discharge channel 12 is provided inside the L-shaped housing 1. A crushing device 2, an anti-blocking mechanism 3, a wood chip pressing mechanism 4, and a discharge assembly 5 are installed on the L-shaped housing 1. The crushing device 2 includes two crushing rollers 25, which are meshed together and rotatably mounted inside the L-shaped housing 1 via shafts. The wood chip pressing mechanism 4 includes an electric push rod 41, which is fixedly mounted on the outer surface of the L-shaped housing 1. The piston rod of the electric push rod 41 extends movably into the discharge channel 12 and is fixedly connected to a pressure plate 42. The discharge assembly 5 includes a stop block 51, which, along with the pressure plate 42, is slidably disposed inside the discharge channel 12. Two guide rods 52 are fixedly connected to the stop block 51. The guide rods 52 movably penetrate the outside of the L-shaped housing 1 and are fixedly connected to a second limiting device. The second limiting block 521 is fixedly connected to the L-shaped housing 1 by a return spring 53, which is sleeved on the outer surface of the guide rod 52. Waste generated from wood processing is fed into the discharge channel 12 inside the L-shaped housing 1 through the feed hopper 11. It is crushed by two meshing and counter-rotating crushing rollers 25. The crushed material falls between the stop block 51 and the pressure plate 42. The piston rod of the electric push rod 41 drives the pressure plate 42 to move towards the stop block 51, causing the crushed material to be crushed. The wood chips are pressed into a block structure. The stop block 51 drives the two guide rods 52 to slide along the L-shaped housing 1 and causes the return spring 53 to deform. When the piston rod of the electric push rod 41 returns to its original position, the stop block 51 returns to its original position under the action of the return spring 53. Due to the frictional resistance between the guide rod 52 and the L-shaped housing 1, the return speed of the stop block 51 is slow, which causes the wood chips pressed into a block structure to be discharged from the L-shaped housing 1. This reduces the space occupied by the crushed wood chips and facilitates transportation for subsequent production and processing.

[0020] See also Figure 3 and Figure 4 The discharge channel 12 includes a crushing chamber 121, a T-shaped chamber 122, and an inclined chamber 123. Two crushing rollers 25 are rotatably installed inside the crushing chamber 121. A stop block 51 and a pressure plate 42 are slidably installed at the bottom of the T-shaped chamber 122, and the surfaces of the stop block 51 and the pressure plate 42 are in contact with the inner wall of the bottom of the T-shaped chamber 122. Wood waste enters the crushing chamber 121 and is crushed by the two crushing rollers 25. The debris falls into the T-shaped chamber 122 for buffering. The electric push rod 41 can be activated intermittently to move the pressure plate 42 along the bottom of the T-shaped chamber 122 toward the stop block 51, so that the debris is squeezed into blocks.

[0021] See also Figure 3 and Figure 4The shafts of the shredder rollers 25 are all fixedly connected to gears 24, and the two gears 24 are meshed together. The L-shaped housing 1 is fixedly provided with a mounting base 22, and a first motor 21 is fixedly installed on the mounting base 22. The output end of the first motor 21 is driven by a belt mechanism 23. The pulley at the upper end of the belt mechanism 23 is driven by a shaft of one shredder roller 25. The output end of the first motor 21 drives the belt mechanism 23 to rotate, which can realize the synchronous reverse rotation of the two gears 24, thereby causing the two shredder rollers 25 to crush the wood waste.

[0022] See also Figure 3 and Figure 4 The outer surface of the guide rod 52 is fixedly fitted with a damping sleeve to delay the reset spring 53 from forcing the stop block 51 to reset. After the guide rod 52 moves with the stop block 51, the reset spring 53 can be deformed. When the pressure plate 42 resets, the reset spring 53 forces the stop block 51 to reset. Because there is frictional resistance between the damping sleeve on the guide rod 52 and the L-shaped housing 1, the reset speed of the stop block 51 can be delayed, thereby causing the pressed block fragments to fall into the inclined cavity 123.

[0023] See also Figure 3 and Figure 4 Two sliding rods 43 are fixedly provided on the pressure plate 42. The sliding rods 43 move through the outside of the L-shaped housing 1 and are fixedly connected to the first limiting block 431. The width of the pressure plate 42 is greater than the vertical cavity width of the T-shaped cavity 122. When the pressure plate 42 moves, it can be guided and slid by the two sliding rods 43. The maximum movement stroke of the pressure plate 42 can be limited by setting the first limiting block 431.

[0024] See also Figure 3 and Figure 4 The vertical cross-sections of the pressure plate 42 and the stop block 51 are both rectangular structures with the same area. When the pressure plate 42 starts to squeeze the debris, the upper surface of the pressure plate 42 moves along the inner wall of the T-shaped cavity 122, which can block the T-shaped cavity 122 and prevent debris from entering the space between the pressure plate 42 and the stop block 51.

[0025] See also Figure 1 and Figure 3 The anti-blocking mechanism 3 includes a second motor 31, which is fixedly mounted on the outer surface of the L-shaped housing 1. The output end of the second motor 31 extends movably into the vertical cavity of the T-shaped cavity 122 and is fixedly provided with multiple stirring rods 32. In order to avoid the phenomenon of debris blocking the vertical cavity of the T-shaped cavity 122, the output end of the second motor 31 drives the multiple stirring rods 32 to rotate, which can stir and process the debris in the vertical cavity of the T-shaped cavity 122.

[0026] Working principle: Waste generated from wood processing is fed into the discharge channel 12 inside the L-shaped housing 1 through the feed hopper 11. It is crushed by two meshing and counter-rotating crushing rollers 25. The chips fall between the stop block 51 and the pressure plate 42. The piston rod of the electric push rod 41 drives the pressure plate 42 to move towards the stop block 51, so that the chips are squeezed into a block structure. The stop block 51 drives the two guide rods 52 to slide along the L-shaped housing 1 and deforms the return spring 53. When the piston rod of the electric push rod 41 returns to its original position, the stop block 51 returns to its original position under the action of the return spring 53. Under the frictional resistance between the guide rods 52 and the L-shaped housing 1, the return speed of the stop block 51 is slow, so that the chips that have been crushed into a block structure are discharged from the L-shaped housing 1. This reduces the space occupied by the crushed wood chips and facilitates transportation for subsequent production and processing.

[0027] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] 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.
