Description

Technical Field

[0001] This utility model belongs to the field of electric planer technology, and in particular relates to a high-efficiency electric planer with a dust removal and chip collection device. Background Technology

[0002] An electric planer is a power woodworking tool primarily used to plan the surface of wood, making it flat, smooth, or shaped into specific forms. It cuts wood using a high-speed rotating blade; during operation, a motor drives the blades to move across the wood surface, quickly removing excess material.

[0003] When an electric planer operates at high speed, the sharp blades rub violently against the wood, instantly producing a large amount of wood chips. These chips fly outwards at extremely high speeds, forming a messy rain of wood dust. The wood chips and debris are scattered everywhere, not only accumulating into a messy layer on the ground, but also bouncing into the gaps and corners around the workbench, and even sticking to the walls and equipment surfaces, making subsequent cleanup work tedious.

[0004] Even more worrying is the presence of fine wood dust, almost invisible to the naked eye. These particles float lightly in the air, drifting with the airflow and forming a hazy, misty area. These tiny particles are easily inhaled by operators, and prolonged exposure to such an environment can lead to more serious respiratory illnesses. Without effective protective measures in a woodworking workshop, the sawdust flying during electric planing not only affects the cleanliness of the work environment but also poses a potential threat to the health of the operators. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a high-efficiency electric planer with a dust collection device, which facilitates installation and disassembly while simultaneously cleaning and collecting debris, thus maintaining a clean and orderly working environment.

[0021] Please see Figures 1 to 7 The embodiments provided by this utility model are as follows: Example: A high-efficiency electric planer with a dust collection and chip removal device, comprising: The electric planer body 1 has a collection cylinder 7 installed inside it. A mounting ring 8 is fixed at the front end of the collection cylinder 7. A connecting ring 13 is inserted into the mounting ring 8. Positioning posts 25 are installed at the upper and lower ends of the outer wall of the connecting ring 13. The positioning posts 25 pass through the mounting ring 8. A collection tube 3 is fixed inside the connecting ring 13. A collection shell 2 is installed at the front end of the collection tube 3. A filter screen 19 is detachably installed inside the collection shell 2. A threaded cap 16 is detachably installed at the front end of the collection shell 2.

[0022] At the front end of the collecting cylinder 7, the fixed mounting ring 8 acts as a precise connecting hub, into which the connecting ring 13 can be inserted to form a stable connection structure. The positioning posts 25 at the upper and lower ends of the outer wall of the connecting ring 13 pass through the mounting ring 8, ensuring a secure fixation between the two and allowing for easy disassembly when needed, guaranteeing the stability of the collecting assembly installation and the convenience of assembly and disassembly. The collecting tube 3 fixed inside the connecting ring 13 acts as an efficient transmission channel, conveying the collected debris forward. The collecting shell 2 installed at its front end further processes the debris. The removable filter 19 inside the collecting shell 2 effectively filters sawdust and dust, intercepting larger debris to prevent it from entering subsequent channels and causing blockages, greatly improving the smoothness of the entire system. The removable threaded cap 16 at the front end of the collecting shell 2 greatly facilitates the cleaning and replacement of the filter 19, allowing maintenance work to be completed without complicated operations. This forms a complete closed loop from debris generation to collection, filtration, and maintenance, significantly improving the dust collection efficiency of the electric planer and making daily maintenance of the equipment simpler and more convenient.

[0023] The electric planer body 1 has a mounting hole 6 at the front end, a discharge port 5 inside the mounting hole 6, and a blade below the discharge port 5. The collecting cylinder 7 is installed inside the mounting hole 6, and a collecting groove 11 is opened at the front end of the collecting cylinder 7. A discharge port 12 is opened at one end of the inner wall of the collecting groove 11, and the discharge port 12 is aligned with the discharge port 5.

[0024] The mounting hole 6 at the front end of the electric planer body 1 provides precise positioning for the installation of the collecting cylinder 7, allowing the collecting cylinder 7 to perfectly fit the electric planer body 1. The discharge port 5 inside the mounting hole 6 is cleverly matched with the position of the blade below. When the blade is performing planing operations, the generated wood chips can directly enter the discharge port 5 under the action of its own inertia and working force, avoiding wood chips flying everywhere or accumulating randomly inside the electric planer. After the collecting cylinder 7 is installed in the mounting hole 6, the collecting groove 11 at its front end becomes an important space to receive the wood chips transported from the discharge port 5. The discharge port 12 at one end of the inner wall of the collecting groove 11 is precisely aligned with the discharge port 5, realizing a seamless connection of wood chips from the inside of the electric planer to the collecting cylinder 7. The wood chips can smoothly enter the collecting groove 11 along these two aligned discharge ports, reducing the residue of wood chips inside the electric planer, ensuring the continuity of the chip collection process, further improving chip collection efficiency, and ensuring that all chips are collected in a timely manner.

[0025] An annular groove 9 is provided at the front end of the mounting ring 8, and positioning holes 10 are provided at the upper and lower ends of the mounting ring 8. A circular groove 23 is provided at the upper and lower ends of the connecting ring 13. A spring 24 is fixed in the circular groove 23, and the spring 24 fixes the positioning post 25. The positioning post 25 passes through the positioning hole 10.

[0026] The annular groove 9 at the front end of the mounting ring 8 provides a clear guide for the installation of the connecting ring 13. When the connecting ring 13 is inserted into the mounting ring 8, the annular groove 9 guides the connecting ring 13 into place accurately, avoiding misalignment and deviation during installation, and greatly improving the efficiency and accuracy of installation. The positioning holes 10 at the upper and lower ends of the mounting ring 8 cooperate with the circular grooves 23 at the upper and lower ends of the connecting ring 13. The spring 24 fixed in the circular groove 23 pushes the positioning post 25 outward. When the connecting ring 13 is installed in place, the positioning post 25 passes through the positioning hole 10 under the force of the spring 24, realizing the automatic locking and fixing of the connecting ring 13 and the mounting ring 8. The whole process does not require additional fixing tools and is simple and quick to operate. When disassembly is required, simply press the positioning post 25 gently to compress the spring 24 and make it exit the positioning hole 10, so that the connecting ring 13 can be easily separated from the mounting ring 8. This simplifies the disassembly and assembly process between the collection pipe 3 and the collection cylinder 7, making equipment maintenance and component replacement more efficient and saving a lot of time and labor costs.

[0027] The rear end of the collection tube 3 penetrates into the collection trough 11.

[0028] The rear end of the collecting pipe 3 extends into the collecting trough 11, allowing it to directly reach the core collecting area of ​​the collecting cylinder 7—the collecting trough 11. This ensures that sawdust in the collecting trough 11 enters the collecting pipe 3 in the shortest possible distance, reducing the residence time and accumulation of sawdust within the trough 11. This prevents blockage of the collecting trough 11 due to excessive sawdust accumulation, ensuring unobstructed flow of the sawdust collection channel and enhancing the overall smoothness of the sawdust collection system. Simultaneously, the direct penetration improves the efficiency of sawdust entering the collecting pipe 3, allowing for continuous and efficient collection, further enhancing the overall dust and sawdust collection efficiency.

[0029] The front end of the collection pipe 3 is fixed with pipe 22, and the front end of pipe 22 is fixed with collection shell 2.

[0030] The pipe 22, fixed at the front end of the collecting pipe 3, plays a crucial connecting and supporting role in the entire chip collection system. The design of pipe 22 extends the chip collection path, allowing for more time and space for the transport of sawdust and dust, preventing chip congestion caused by a short path. Simultaneously, pipe 22 provides stable installation support for the front-end collecting shell 2, ensuring it is firmly fixed in the appropriate position and will not shift or loosen due to vibrations during electric planing operation. This allows the collecting shell 2 to more accurately collect sawdust and dust from the collecting pipe 3, ensuring the stability of the chip collection process, effectively preventing leakage of sawdust during transport, and improving the success rate of chip collection.

[0031] The front end of the collection shell 2 is provided with a collection groove 14, and a fixing plate 15 is fixed on the inner wall of the collection groove 14. The front end of the fixing plate 15 is provided with a threaded hole 21, and a threaded plate 20 is connected to the threaded hole 21. The filter screen 19 is fixed to the threaded plate 20.

[0032] The collection groove 14 at the front end of the collection shell 2 provides space for further processing of wood chips. The fixed plate 15 and threaded plate 20, fixed to its inner wall, are threadedly connected via threaded holes 21, facilitating the installation and removal of the filter screen 19. The filter screen 19 is fixed to the threaded plate 20. When the filter screen 19 becomes clogged with wood chips due to prolonged use or needs cleaning, simply rotate the threaded plate 20 to unscrew it from the fixed plate 15, and the filter screen 19 can be removed along with it. The operation is simple and convenient, requiring no professional tools or skills. The filter screen 19 effectively filters out larger wood chips, preventing these large particles from entering subsequent pipes and causing blockages. This ensures the normal operation of the entire chip collection system, significantly improves the durability of the chip collection device, and extends the service life of the equipment.

[0033] The front end of the collection shell 2 has a threaded groove, and the threaded cover 16 is threaded into the threaded groove. The front end of the threaded cover 16 is fixed to the pipe 18, and the front end of the pipe 18 is fitted with a flexible hose 4.

[0034] The threaded groove at the front end of the collecting shell 2 and the threaded connection of the threaded cover 16 make the installation and removal of the threaded cover 16 very convenient. Simply rotating the threaded cover 16 allows it to be separated from or connected to the collecting shell 2. This greatly facilitates cleaning the inside of the collecting shell 2. When a certain amount of debris accumulates inside the collecting shell 2, the threaded cover 16 can be quickly opened for cleaning, ensuring the normal operation of the collecting shell 2. The pipe 18 fixed to the front end of the threaded cover 16 and the flexible hose 4 connected to its front end expand the debris collection range. Filtered fine dust or excess sawdust can be guided to the external collection container through the pipe 18 and the flexible hose 4. This not only prevents fine dust from spreading into the working environment and reduces air pollution, but also allows for centralized collection and processing of debris, improving the cleanliness of the working environment and providing operators with a healthier and more comfortable working environment.

[0035] The screw cap 16 has handles 17 fixed on both sides of its front end.

[0036] The handles 17 fixed on both sides of the front end of the threaded cap 16 provide convenient points of force for rotating and disassembling the threaded cap 16. The handles 17 allow the operator to apply force more effortlessly, making both tightening and loosening of the threaded cap 16 easier. Especially when the threaded cap 16 has accumulated a lot of dust due to prolonged use, making it difficult to rotate, the advantage of the handles 17 is even more obvious, effectively preventing the operator from slipping during the application of force, thus improving the safety and efficiency of operation.

[0037] In this embodiment, when the operator is about to use the electric planer, the blades at the bottom of the electric planer will quickly generate a large amount of wood chips the moment they come into contact with the wood at high speed. If these wood chips are not dealt with in time, they will not only affect the operator's field of vision, but may also fly around and pollute the environment. At this point, the operator only needs to align the connecting ring 13 with the annular groove 9 at the front end of the mounting ring 8 and gently apply a pushing force. The connecting ring 13 will then smoothly enter the installation position along the guide of the annular groove 9. During this process, the springs 24 in the circular grooves 23 at both ends of the connecting ring 13 will undergo elastic deformation due to the compression of the inner wall of the mounting ring 8, causing the positioning post 25 to retract inward. When the connecting ring 13 is fully in place, the positioning post 25 corresponds exactly to the positioning hole 10 on the mounting ring 8. The spring 24 then returns to its original shape, pushing the positioning post 25 outward so that it accurately passes through the positioning hole 10, thereby firmly locking the connecting ring 13 and the mounting ring 8. This ensures that the entire collection assembly remains stable even when the electric planer is running at high speed, without any loosening or displacement. Next, the operator attaches one end of the hose 4 to the pipe 18 at the front end of the threaded cap 16, and the other end to the external power storage device. When the power storage device is activated, it creates a continuous negative pressure suction throughout the chip collection channel, providing strong power for the transport of wood chips. Under the suction, the wood chips generated by the electric planer blades enter the collection trough 11 of the collection cylinder 7 through the discharge port 5 inside the electric planer body 1, and then enter the rear end of the collection pipe 3 that runs through it through the discharge port 12 on the inner wall of the collection trough 11. Wood chips entering the collection pipe 3 are conveyed forward along the pipe under negative pressure, and smoothly enter the collection tank 14 inside the collection shell 2 via the pipe 22 fixed at the front end of the collection pipe 3. The filter screen 19 is fixed on the threaded disc 20, and the threaded disc 20 is tightly connected to the fixed disc 15 on the inner wall of the collection tank 14 through the threaded hole 21, forming a strong filtration barrier. Larger wood chips are effectively intercepted by the filter screen 19 and temporarily stored in the collection tank 14 to prevent them from entering the subsequent pipes and causing blockages; while the finer chips and dust can pass smoothly through the filter screen 19 and continue to move forward, entering the hose 4 through the pipe 18 on the threaded cover 16, and finally being sucked into the power storage device for centralized collection. Throughout the process, from the generation of wood chips by the blades, to the rapid locking of the connecting ring 13 and the mounting ring 8, and then to the suction force generated by the power storage device through the hose 4, driving the wood chips sequentially through the collection pipe 3 and the second pipe 22 into the collection shell 2, where they are filtered by the filter screen 19 to achieve coarse and fine separation, all structural components work together in a coordinated manner to form an efficient and continuous wood chip processing flow. Whether it is the stable connection between the connecting ring 13 and the mounting ring 8 ensuring the sealing of the channel, the precise filtration of the filter screen 19 achieving the graded processing of wood chips, or the cooperation between the hose 4 and the power storage device providing continuous power, the electric planer can maintain a clean and orderly working environment while operating efficiently. When the work is finished or cleaning is required, the operator only needs to press the positioning post 25 to release the lock between the connecting ring 13 and the mounting ring 8, facilitating maintenance of components such as the collection pipe 3. To clean larger wood chips from the filter screen 19, the handle 17 at the front end of the threaded cover 16 can be rotated to unscrew the threaded cover 16 from the threaded groove at the front end of the collection shell 2. Then, the threaded disc 20 can be rotated to separate it from the fixed disc 15, allowing the filter screen 19 to be easily removed for cleaning or replacement. The entire operation is simple and convenient, requiring no complicated tools, fully meeting the needs of efficient operation and convenient maintenance. It achieves the effect of easy installation and disassembly, while also allowing for the collection and cleaning of debris, maintaining a clean and orderly working environment.
