Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a structural schematic diagram of the present invention from another angle; Figure 3 This is a cross-sectional structural diagram of the present invention. It includes: a housing 1, a pressing mechanism, a pushing mechanism, a negative pressure mechanism, and a dust extraction mechanism.

[0020] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3 As shown, one side of the housing 1 has an air inlet 14, and the other side has an exhaust outlet 7. A matching dustproof net 17 is installed inside the exhaust outlet 7. The front end of the housing 1 is fixedly connected to a discharge pipe 2, and an electric gate valve 3 is installed on the discharge pipe 2. A pressing mechanism is installed on the upper surface of the housing 1. The pressing mechanism includes a cylinder 19 and a pressing plate 18. The cylinder 19 is installed on the upper surface of the housing 1, and the output end of the cylinder 19 passes through the upper surface of the housing 1 and is fixedly connected to a device that matches the inner cavity of the housing 1. The rear end face of the housing 1 is connected to a push mechanism, which includes a cover 12, an electric push rod 11, and a push plate 16. The rear end face of the housing 1 is fixedly connected to the cover 12. The rear end face of the cover 12 is equipped with an electric push rod 11. The output end of the electric push rod 11 passes through the side of the cover 12 and is fixedly connected to the push plate 16. One side of the housing 1 is connected to a negative pressure mechanism, which is connected to the exhaust port 7. One side of the housing 1 is connected to a dust extraction mechanism, which is connected to the air inlet 14.

[0021] It should be noted that during use, the operator first secures the opening of an empty packaging bag to the outside of the discharge pipe 2 on the side of the equipment housing 1 using methods such as bundling, clamps, or elastic rings. During operation, a negative pressure mechanism creates negative pressure inside the housing 1, drawing sawdust dust into the housing 1 through the dust extraction mechanism. The sawdust dust is filtered by the dust filter 17 and collected inside the housing 1. When the sawdust dust in the collection box reaches a preset height, the cylinder 19 is activated, causing the pressure plate 18 to move downwards until it is flush with the upper surface of the discharge pipe 2. This forcefully compresses the loose dust at the bottom of the housing 1 into a shape and density. The block is pressed, then the cylinder 19 returns to its original position, causing the pressure plate 18 to reset. Then the electric gate valve 3 is activated, opening the channel from the inside of the box 1 to the outer packaging bag. Then the electric push rod 11 is activated, which drives the push plate 16 to move horizontally, so that the block is smoothly and completely pushed horizontally from the bottom of the box 1 into the discharge pipe 2, and finally directly fills the inside of the already packaged bag. When the block is completely inside the packaging bag, the electric push rod 11 is activated to reset the push plate 16, and then the electric gate valve 3 is closed. At this time, the operator only needs to untie the bag opening tied to the discharge pipe 2, and a clean packaging bag containing the compacted wood chips is completed. The operator can seal and transfer it at any time.

[0022] refer to Figure 1 As shown, the negative pressure mechanism includes a fan 9, an exhaust pipe 10, and an exhaust hopper 8. The fan 9 is installed on one side of the housing 1. The inlet of the fan 9 is fixedly connected to the exhaust pipe 10. The other end of the exhaust pipe 10 is fixedly connected to the exhaust hopper 8. The exhaust hopper 8 is fixedly connected to the exhaust port 7.

[0023] It should be noted that when performing negative pressure operation, the fan 9 is started. The fan 9 draws air through the exhaust pipe 10 and the exhaust duct 8, which creates negative pressure inside the box 1.

[0024] refer to Figure 1 and Figure 2 As shown, the dust extraction mechanism includes a hose 5 and a suction head 6. The air inlet 14 is fixedly connected to the hose 5, and the other end of the hose 5 is fixedly connected to the suction head 6.

[0025] It should be noted that when negative pressure is generated inside the chamber 1, the hose 5 and the suction head 6 will draw air in, drawing the gas containing wood dust into the chamber 1.

[0026] refer to Figure 2 As shown, a matching coarse screen 15 is fixedly connected inside the suction head 6. The coarse screen 15 prevents excessive impurities from being sucked in and causing blockage of the pipe.

[0027] refer to Figure 2 As shown, an observation port is provided on one side of the box 1, and a matching observation window 13 is installed inside the observation port. Through the observation window 13, it is convenient to see the volume of wood chips and dust inside the box 1, so as to facilitate timely compression and packaging.

[0028] refer to Figure 1 As shown, a matching rectangular baffle 4 is fixedly connected to the discharge pipe 2. The rectangular baffle 4 serves to prevent the packaging bag from slipping, so that the packaging bag fixed on the discharge pipe 2 can be more stable during the packaging process.

[0029] The working principle of this utility model is as follows: In use, the operator first secures the opening of an empty packaging bag to the outside of the discharge pipe 2 on the side of the equipment housing 1 using a tie, clamp, or elastic ring. During use, the blower 9 is started. The blower 9 draws air through the exhaust pipe 10 and exhaust duct 8, creating a negative pressure inside the housing 1. This causes the hose 5 and suction head 6 to draw air in, drawing the gas containing wood dust into the housing 1. The wood dust is then filtered through the dustproof net 17. The dust collector collects wood chips and dust inside the collection box 1. When the wood chips and dust in the collection box reach a preset height, the cylinder 19 is activated, causing the pressure plate 18 to move downwards until it is flush with the upper surface of the discharge pipe 2. This forcefully compresses the loose dust at the bottom of the collection box 1 into a block with a certain shape and density. Then, the cylinder 19 returns to its original position, causing the pressure plate 18 to reset. Next, the electric gate valve 3 is activated, opening the channel from the inside of the collection box 1 to the outer packaging bag. Finally, the electric push rod 11 is activated. The electric push rod 11 drives the push plate 16 to move horizontally, so that the compressed block is smoothly and completely pushed horizontally from the bottom of the box 1 into the discharge pipe 2, and finally directly filled into the already packaged bag. After the compressed block is completely in the packaging bag, the electric push rod 11 is activated to reset the push plate 16, and then the electric gate valve 3 is closed. At this time, the operator only needs to untie the bag opening tied to the discharge pipe 2, and a clean packaging bag containing the compressed wood chips is processed. The operator can seal and transfer it at any time. In summary, this device can automatically complete the compression and packaging of wood chips. Moreover, the entire packaging process, from compression to filling, is completed in the closed environment of the box 1, the discharge pipe 2, and the packaging bag, and is never exposed to the open environment. This completely solves the problem of secondary dust generated when manually dumping and transferring wood chips, greatly improves the working environment, and by automating the compression and filling, the manual shoveling and bagging operations are eliminated, which not only reduces labor intensity but also improves efficiency.

[0030] In this utility model, cylinder 19 is connected to an existing pneumatic system (including an air compressor, an air tank, a filter pressure reducing valve, a directional control valve, and pneumatic pipelines). After the compressed air is dried and purified, the airflow direction and pressure are adjusted by the control valve to drive the cylinder piston to move. This is prior art and will not be described in detail here. Other circuits and controls involved are also prior art and will not be described in detail here either.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
