[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown, an embodiment of the present utility model proposes a sawdust recovery device for furniture processing, which is used to compress sawdust generated during the production process of wooden furniture to facilitate subsequent recycling and reuse of the sawdust.

[0025] Please refer to Figure 1 and Figure 2The wood chip recovery device for furniture processing includes a box body 1, wherein the box body 1 has a compression chamber 11 for accommodating wood chips, a top of the box body 1 is provided with a feed port 12 communicated with the compression chamber 11, and a bottom of the box body 1 is provided with a discharge port 13 communicated with the compression chamber 11, wood chips are put into the compression chamber 11 from the feed port 12, and the compressed wood chips are discharged from the discharge port 13; a liftable upper pressing plate 2 is provided in the compression chamber 11, and a first driving component 3 is provided on the box body 1 that is transmission-connected with the upper pressing plate 2, the first driving component 3 drives the upper pressing plate 2 to approach or move away from the discharge port 13 in the vertical direction, and the wood chips in the compression chamber 11 can be compacted by driving the upper pressing plate 2 downward by the first driving component 3, and a rotatable supporting plate 4 and a second driving component 5 transmission-connected with the supporting plate 4 are also provided on the box body 1. The support plate 4 covers the opening of the discharge port 13, and the support plate 4 is driven by the second driving component 5 to rotate to control the opening or closing of the discharge port 13; a material receiving rack 6 and a discharge conveyor belt 7 are also provided under the box body 1, and the material receiving rack 6 includes a material receiving plate 61 and the height of the end of the material receiving plate 61 close to the discharge port 13 is higher than the height of the end of the material receiving plate 61 away from the discharge port 13, and the discharge conveyor belt 7 is located on the side of the material receiving plate 61 away from the discharge port 13 and the end of the material receiving plate 61 away from the discharge port 13 is located above the discharge conveyor belt 7. After the discharge port 13 is opened, the compressed block wood chips in the compression chamber 11 fall on the material receiving plate 61 and move along the material receiving plate 61 to the discharge conveyor belt 7. At this time, the block wood chips can be transported to the designated position through the discharge conveyor belt 7.

[0026] Specifically, the working process of the wood chip recovery device for furniture processing provided in this embodiment is as follows: wood chips are poured into the compression chamber 11 from the feed port 12, and when a sufficient amount of wood chips is accumulated in the compression chamber 11, the first driving component 3 drives the upper pressure plate 2 to descend. At this time, the wood chips in the compression chamber 11 are compressed into blocks after being subjected to the pressure of the upper pressure plate 2, and the block wood chips are accumulated on the support plate 4 near the discharge port 13. The first driving component 3 drives the upper pressure plate 2 to rise and fall back and forth several times for compression. After the compression is completed, the second driving component 5 drives the support plate 4 to rotate and open the discharge port 13. At this time, the block wood chips are discharged from the discharge port 13 under the action of gravity and fall along the support plate 4 onto the receiving plate 61. The block wood chips slide along the receiving plate 61 until they fall on the discharge conveyor belt 7. The block wood chips are transported to the designated position for storage by the discharge conveyor belt 7, and the discharge can be automatically completed. The wood chip recovery device for furniture processing provided in this embodiment can automatically discharge the compressed block wood chips and transport them to a designated location, thereby improving the degree of automation of the equipment, and helping to reduce the labor intensity of workers and save manpower.

[0027] like Figure 1 、 Figure 2 and Figure 5 As shown, the box body 1 is provided with a feed pipe 14 connected to the feed port 12, and a feed hopper 15 connected to the feed pipe 14 is provided at one end of the feed pipe 14 away from the box body 1. The feed pipe 14 and the feed hopper 15 are provided on the box body 1 and are connected to the feed port 12 in sequence. When wood chips are poured into the feed hopper 15, the wood chips can be guided through the feed port 12 into the compression chamber 11 through the feed pipe 14, so that the wood chips can be poured into the box body 1 and prevented from being scattered outside the box body 1 during the process of being poured into the box body 1.

[0028] In detail, the compression chamber 11 includes a accommodating portion 16, a material guiding portion 17 and a compression portion 18 which are connected in sequence from top to bottom. The feed pipe 14 is connected to the accommodating portion 16. The shape of the cross section of the compression portion 18 is consistent with the shape of the upper pressure plate 2 and the discharge port 13 is located at one end of the compression portion 18 away from the material guiding portion 17. After passing through the feed port 12 along the feed pipe 14, the wood chips first enter the accommodating portion 16, and slide into the compression portion 18 along the inner wall of the guide portion 17 so that the wood chips are accumulated in the compression portion 18, and the cross-sectional area of ​​the compression portion 18 is consistent with the shape of the upper pressing plate 2, so that the wood chips in the compression portion 18 can all be compressed by the upper pressing plate 2, and after the upper pressing plate 2 rises and exits the compression portion 18, the wood chips in the accommodating portion 16 continue to enter the compression portion 18 along the guide portion and accumulate, so that the upper pressing plate 2 continues to compact the wood chips in the compression chamber 11 during the reciprocating lifting process, which is beneficial to improving the reliability of the wood chip recovery device for furniture processing.

[0029] like Figure 2 and Figure 5 As shown, a feed conveyor 8 is provided on the feed pipe 14. The feed conveyor 8 includes a motor 81 and a conveying rod 82 provided at the output end of the motor 81. The conveying rod 82 extends into the feed pipe 14, and a spiral blade 83 is provided on the portion of the conveying rod 82 located within the feed pipe 14. The feed conveyor 8 provided on the feed pipe 14 is used to continuously feed wood chips from the feed hopper 15 into the compression chamber 11. The motor 81 drives the conveying rod 82 to rotate, thereby driving the spiral blade 83 to rotate, thereby driving the wood chips from the feed hopper 15 to the feed port 12, and preventing wood chips from accumulating in the feed pipe 14 and causing the feed pipe 14 to be blocked, thereby ensuring the smooth operation of the wood chip recovery device for furniture processing.

[0030] Please combine Figure 2 and Figure 3 The first driving assembly 3 includes a first oil cylinder 31 and a first piston rod 32 provided at the output end of the first oil cylinder 31. One end of the first piston rod 32 extends into the compression chamber 11 and cooperates with the upper pressing plate 2. The first oil cylinder 31 drives the first piston rod 32 to extend or retract into the first oil cylinder 31, thereby driving the upper pressing plate 2 to rise and fall vertically in the compression chamber 11. When the first piston rod 32 extends from the first oil cylinder 31, the upper pressing plate 2 descends vertically. At this time, the upper pressing plate 2 applies pressure to the wood chips in the compression chamber 11 and compacts the wood chips. When the first piston rod 32 retracts into the first oil cylinder 31, the upper pressing plate 2 rises vertically. At this time, the upper pressing plate 2 is reset and enables the wood chips in the compression chamber 11 to move toward the discharge port 13.

[0031] In this embodiment, a connecting plate 33 is provided at one end of the first piston rod 32 extending into the compression chamber 11. The connecting plate 33 is provided with a plurality of first through holes at intervals. The upper pressing plate 2 is provided with a first connecting rod 21 that cooperates with the first through holes. A first spring 22 is sleeved on the first connecting rod 21. The opposite ends of the first spring 22 in the direction of expansion and contraction respectively abut against the connecting plate 33 and the upper pressing plate 2, thereby driving the upper pressing plate 2 to move away from the connecting plate 33. When the wood chips in the compression chamber 11 are compacted and the upper pressing plate 2 continues to descend, the upper pressing plate 2 moves toward the connecting plate 33 and the first spring 22 is further compressed. The first spring 22 acts as a buffer, preventing the upper pressing plate 2 from continuing to press downward and causing damage to the wood chip recovery device for furniture processing. When the upper pressing plate 2 rises under the drive of the first driving assembly 3, the first spring 22 returns to its original length and pushes the upper pressing plate 2 to return to its original position, thereby improving the stability of the wood chip recovery device for furniture processing.

[0032] like Figure 2 As shown, two guide plates 19 are spaced apart on the box body 1. The two guide plates 19 are located on opposite sides of the feed port 12 and extend toward the receiving plate 61. The two guide plates 19 provided on the box body 1 are used to guide the block wood chips to fall onto the receiving plate 61, preventing the block wood chips from sliding off the support plate 4 and outside the receiving rack 6 when discharged from the discharge port 13, thereby ensuring that the block wood chips are smoothly transported to the designated location on the wood chip recovery device for furniture processing.

[0033] Please refer to Figure 2 and Figure 5 The second driving assembly 5 includes a second oil cylinder 51 and a second piston rod 52 provided at the output end of the second oil cylinder 51. The end of the second oil cylinder 51 away from the second piston rod 52 is rotatably connected to the housing 1, and the end of the second piston rod 52 away from the second oil cylinder 51 is rotatably connected to the support plate 4. The second oil cylinder 51 drives the second piston rod 52 to extend or retract the second oil cylinder 51 to drive the support plate 4 to rotate on the housing 1. When the second oil cylinder 51 drives the second piston rod 52 to extend the second oil cylinder 51, the support plate 4 rotates to a position that closes the discharge port 13. The second piston rod 52 supports the support plate 4 so that the support plate 4 remains in the position that closes the discharge port 13 while the upper pressing plate 2 is pressing the wood chips. When the second oil cylinder 51 drives the second piston rod 52 to retract the second oil cylinder 51, the support plate 4 rotates to a position that opens the discharge port 13. At this time, the blocky wood chips in the compression chamber 11 are discharged and discharged.

[0034] like Figure 4 and Figure 5 As shown, baffles 62 are respectively provided on opposite sides of the receiving plate 61, and the distance between the two baffles 62 is smaller than the width of the discharge conveyor belt 7. The baffles 62 provided on both sides of the receiving plate 61 are used to block the block wood chips moving on the receiving plate 61, preventing the block wood chips from falling outside the receiving rack 6 when falling, and ensuring that the block wood chips are stably fed into the discharge conveyor.

[0035] Specifically, the receiving frame 6 further includes a frame body 63, on which a plurality of second through holes are spaced apart, and the receiving plate 61 is provided with a second connecting rod 64 that matches the second through holes. A second spring 65 is sleeved on the second connecting rod 64, and opposite ends of the second spring 65 in the direction of expansion and contraction respectively abut against the frame body 63 and the receiving plate 61, thereby driving the receiving plate 61 to move away from the frame body 63. When the block of wood chips falls on the receiving plate 61 along the support plate 4, the impact on the receiving plate 61 causes the second spring 65 to further shorten and then return to its original length, so as to provide a buffer through the expansion and contraction of the second spring 65, thereby preventing the block of wood chips from scattering after colliding with the support plate 4, and thus maintaining a compact shape of the block of wood chips during the unloading process, thereby preventing the block of wood chips from scattering and causing the wood chips to fall.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
