Abstract
Description
Technical Field
[0001] This utility model relates to the field of sawing machine technology, and more specifically, it relates to an automatic waste collection device for a double-end sawing machine. Background Technology
[0002] Double-end saws are used in wood processing to cut off both ends of wood. During operation, they generate a lot of waste (such as wood chips, sawdust, and short pieces of wood). In the early days, manual cleaning was used, which was inefficient. The waste accumulated around the machine, which could easily cause tripping hazards. Some of it was collected by a simple conveyor belt, but wood chips could easily get stuck in the gaps of the conveyor belt, requiring frequent shutdowns for maintenance.
[0003] Traditional collection devices lack a screening structure, resulting in a mixture of sawdust, short pieces of wood, and large particles of waste. This requires manual sorting, which has a relatively high recycling rate. However, traditional screening structures lack active cleaning, and sawdust easily clogs the screen holes, causing fine waste to accumulate on the screening plate. Traditional cleaning boxes are mostly fixed with bolts, and each cleaning takes 10-15 minutes. Furthermore, frequent disassembly and reassembly lead to severe wear on the connecting parts. Utility Model Content
[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides an automatic waste collection device for a double-end saw to solve the technical problems mentioned in the background art.

[0006] The present invention is further configured such that the bottom of the screening plate and the guide plate are provided with sliding blocks, and the first cleaning box and the second cleaning box are provided with sliding grooves that cooperate with the sliding blocks, so as to facilitate the installation of the first cleaning box and the second cleaning box.
[0007] The present invention is further configured such that a drive motor is provided on one side of the swing disk, and the motor shaft of the drive motor is fixedly connected to the swing disk, so as to facilitate the rotation of the swing disk.
[0008] The present invention is further configured such that the limiting device includes a limiting box, the limiting box is fixedly installed on the outer wall of the collection box, the first cleaning box and the second cleaning box are provided with limiting blocks, the limiting box is slidably provided with a snap-fit plate, the snap-fit plate is provided with a snap-fit block, and the limiting block is provided with a snap-fit hole that cooperates with the snap-fit block, so as to facilitate fixing the position of the first cleaning box and the second cleaning box.
[0009] The present invention is further configured such that a compression spring is provided between the snap-fit plate and the limiting box, so that the snap-fit block has a continuous and stable elastic force pointing towards the snap-fit hole.
[0010] The present invention is further configured such that the limiting box is provided with a pressing rod, the bottom of the pressing rod is provided with a pressing block, the bottom of the pressing block is in close contact with the snap-fit plate, so as to facilitate the movement of the snap-fit block and thus the movement of the limiting block.
[0011] The present invention is further configured such that one side of the snap-fit block is an inclined surface, and the contact surface between the limiting block and the squeezing block is an inclined surface, which facilitates the movement of the snap-fit block and the limiting block.
[0012] The present invention is further provided with a protective net on one side of the dust collector to prevent debris from entering the dust collector.
[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides an automatic waste collection device for a double-ended saw, which has the following beneficial effects: 1. The screening plate, in conjunction with the cleaning brush, can separate fine wood chips from large waste particles. The fine waste particles enter the second cleaning box through the guide plate and can be used directly as biomass fuel. The large waste particles enter the first cleaning box, and short wood segments can be processed again, resulting in a high overall recycling rate.
[0014] 2. The drive motor drives the swing disc to rotate, and the swing rod is linked with the swing groove to make the cleaning brush swing back and forth along the screen plate. The brush bristles (nylon material, 0.3mm in diameter) can penetrate deep into the screen holes to remove the wood chips that are clogging the screen holes, reducing the screen hole clogging rate and stabilizing the negative pressure suction, thus avoiding downtime for cleaning due to clogging.
[0015] 3. The limiting device uses a spring to drive the locking block to automatically engage with the locking hole of the limiting block, thus fixing the cleaning box. When removing the box, simply press the squeezing rod, the squeezing block will push the locking plate down, the locking block will disengage from the locking hole, and at the same time push the cleaning box outward, resulting in high efficiency in a single operation.

[0021] Please see Figures 1-5An automatic waste collection device for a double-end saw includes a collection box 1. A dust extraction fan 2 is provided on one side of the collection box 1. A screening plate 3 and a guide plate 4 are provided on the collection box 1. The screening plate 3 and the guide plate 4 are symmetrically arranged in the collection box 1 at an angle downwards. A first cleaning box 5 is provided between the screening plates 3, and a second cleaning box 6 is provided between the guide plates 4. Limiting devices are provided between the first cleaning box 5, the second cleaning box 6 and the collection box 1. A swing plate 7 and a swing disk 8 are rotatably provided on the side wall of the collection box 1. A cleaning shaft 9 is provided at the bottom of the swing plate 7. A cleaning brush 10 is provided on the cleaning shaft 9, a swing rod 11 is eccentrically provided on the swing disk 8, a swing groove 12 that cooperates with the swing rod 11 is provided on the swing plate 7, a sieve hole 13 is provided on the first cleaning box 5 and the sieve plate 3, a sliding block 14 is provided at the bottom of the sieve plate 3 and the guide plate 4, a sliding groove 15 that cooperates with the sliding block 14 is provided on the first cleaning box 5 and the second cleaning box 6, a drive motor 16 is provided on one side of the swing disk 8, the motor shaft of the drive motor 16 is fixedly connected to the swing disk 8, and a protective net 25 is provided on one side of the dust collector fan 2.
[0022] In this embodiment, the vacuum fan 2 is started. The protective net 25 on one side of the vacuum fan 2 prevents waste from entering the vacuum fan 2. After the double-end saw cuts the wood, under the negative pressure of the vacuum fan 2, the debris and dust fall onto the sieve plate 3 in the collection box 1. The drive motor 16 is started, and the drive motor 16 drives the swing disk 8 to rotate. The swing rod 11 on the swing disk 8 rotates, and the swing rod 11 drives the swing plate 7 to swing back and forth in the swing groove 12. The swing plate 7 drives the cleaning shaft 9 and the cleaning brush 10 to swing back and forth, cleaning the upper surface of the sieve plate 3. This allows small debris to fall through the sieve hole 13 onto the guide plate 4 and move along the guide plate 4 to the second cleaning box 6 for collection. Large particles of impurities and waste slide into the first cleaning box 5 for collection under the cleaning effect of the cleaning shaft 9 and the cleaning brush 10. After the limiting device is opened, the first cleaning box 5 and the second cleaning box 6 are taken out and cleaned by the cooperation of the sliding block 14 and the sliding groove 15.
[0023] Please see Figure 5 As one embodiment of the limiting device: the limiting device includes a limiting box 17, which is fixedly installed on the outer wall of the collection box 1. The first cleaning box 5 and the second cleaning box 6 are provided with limiting blocks 18. A snap-fit plate 19 is slidably provided inside the limiting box 17. A snap-fit block 20 is provided on the snap-fit plate 19. A snap-fit hole 21 that cooperates with the snap-fit block 20 is provided on the limiting block 18. A compression spring 22 is provided between the snap-fit plate 19 and the limiting box 17. A pressing rod 23 is provided on the limiting box 17. A pressing block 24 is provided at the bottom of the pressing rod 23. The bottom of the pressing block 24 is in close contact with the snap-fit plate 19. One side of the snap-fit block 20 is an inclined surface. The contact surface between the limiting block 18 and the pressing block 24 is an inclined surface.
[0024] More specifically, when installing the first cleaning box 5 and the second cleaning box 6 onto the collection box 1, align the sliding groove 15 of the first cleaning box 5 and the second cleaning box 6 with the sliding block 14, and insert the first cleaning box 5 and the second cleaning box 6, along with the limiting block 18, into the limiting box 17. The limiting block 18 presses the locking block 20 and the locking plate 19 downwards through the inclined surface, while the locking plate 19 presses down the compression spring 22. When the locking block 20 is aligned with the locking hole 21, the locking plate 19, under the elastic force of the compression spring 22, drives the locking block 20 to extend into the locking hole 21, fixing the position of the limiting block 18, and thus fixing the position of the first cleaning box 5 and the second cleaning box 6. When opening the limiting device, press down the squeezing rod 23 and the squeezing block 24. The squeezing block 24 moves the locking plate 19 downwards, which can drive the locking block 20 away from the locking hole 21. At the same time, through the inclined surface, the squeezing block 24 squeezes the limiting block 18 outwards, making it easier for the first cleaning box 5 and the second cleaning box 6 to move and be removed.
[0025] In summary, during the use or operation of the entire equipment: The dust extraction fan 2 is started. The protective net 25 on one side of the dust extraction fan 2 prevents waste from entering the dust extraction fan 2. After the double-end saw cuts the wood, under the negative pressure of the dust extraction fan 2, the debris and dust fall onto the screening plate 3 in the collection box 1. The drive motor 16 is started, which drives the swing disk 8 to rotate. The swing rod 11 on the swing disk 8 rotates, and the swing rod 11 drives the swing plate 7 to reciprocate within the swing groove 12. The swing plate 7 drives the cleaning shaft 9 and cleaning brush 10 to swing back and forth, cleaning the upper surface of the screening plate 3. This causes fine debris to fall through the screening holes 13 onto the guide plate 4 and move along the guide plate 4 to the second cleaning box 6 for collection. Large particles of impurities and waste slide into the first cleaning box 5 for collection under the cleaning effect of the cleaning shaft 9 and cleaning brush 10. After the limiting device is opened, the first cleaning box 5 and the second cleaning box 6 are taken out and cleaned through the cooperation of the sliding block 14 and the sliding groove 15.
[0026] When installing the first cleaning box 5 and the second cleaning box 6 onto the collection box 1, align the sliding groove 15 of the first cleaning box 5 and the second cleaning box 6 with the sliding block 14, and insert the first cleaning box 5 and the second cleaning box 6, along with the limiting block 18, into the limiting box 17. The limiting block 18 presses the locking block 20 and the locking plate 19 downwards through the inclined surface. At the same time, the locking plate 19 presses down the compression spring 22. When the locking block 20 is aligned with the locking hole 21, the locking plate 19, under the elastic force of the compression spring 22, drives the locking block 20 to extend into the locking hole 21, fixing the position of the limiting block 18, and thus fixing the position of the first cleaning box 5 and the second cleaning box 6. When opening the limiting device, press down the squeezing rod 23 and the squeezing block 24. The squeezing block 24 moves the locking plate 19 downwards, which can drive the locking block 20 away from the locking hole 21. At the same time, through the inclined surface, the squeezing block 24 squeezes the limiting block 18 outwards, making it easier for the first cleaning box 5 and the second cleaning box 6 to be moved and removed.
