Description

Technical Field

[0001] This utility model relates to the field of woodworking machinery technology, and in particular to a planer that automatically collects wood chips. Background Technology

[0002] The main function of a planer is to precisely plan the rough, uneven surface of wood to achieve the desired flatness and smoothness, obtain uniform thickness, and effectively remove burrs and imperfections from the wood surface. This lays a solid foundation for subsequent woodworking processes such as precise cutting, seamless splicing, fine carving, and surface finishing. Therefore, planers are widely used in furniture manufacturing, door and window production, and building decoration industries, and are key equipment for improving the quality and efficiency of wood processing.

[0003] Traditional planers generally suffer from insufficient chip collection capacity during operation. Due to the lack of effective chip collection and handling mechanisms, wood chips and debris generated during planing fly everywhere, severely polluting the working environment. The workshop is often filled with dust, significantly impacting workplace cleanliness and hygiene, and substantially increasing cleaning and maintenance costs and time. More importantly, accumulated wood chips in the work area pose a serious safety hazard. As a flammable material, wood chips can easily ignite a fire under certain conditions, directly threatening the lives of operators. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic debris recovery planer.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic debris recovery planer, comprising: a planer table with an opening at its top; a support frame for supporting the planer table; a side baffle fixed to one side of the top of the planer table; a width limiting component including a horizontal electric cylinder and a movable limiting plate, the telescopic end of the horizontal electric cylinder being connected to the movable limiting plate to drive the movable limiting plate to move closer to or away from the side baffle; and a height limiting component including a fixed frame, a vertical electric cylinder, a lifting plate, and a pressure roller, the fixed frame being fixed to the top of the planer table. The unit consists of a vertical electric cylinder fixed to a fixed frame, with its telescopic end connected to a lifting plate. A pressure roller is rotatably mounted on the lifting plate to drive the pressure roller to move up and down. The recycling component includes a recycling hopper, a motor, and a planer blade. The recycling hopper is located below the planer table, while the motor and planer blade are located on top of the planer table. The planer blade is located at the opening and is connected to the output shaft of the motor to drive the planer blade to rotate. Planing debris falls into the recycling hopper through the opening. A collection box is located below the recycling hopper to collect the debris discharged from the recycling hopper.

[0006] Furthermore, the height limiting component also includes a lifting frame, vertical sliding rods, and a buffer spring. Vertical sliding rods are slidably connected to both ends of the lifting plate, and the top two ends of the lifting frame are fixedly connected to the two vertical sliding rods respectively. The pressure roller is rotatably set at the bottom of the lifting frame, and the buffer spring is sleeved on the vertical sliding rods and located between the lifting plate and the lifting frame.

[0007] More specifically, the width limiting component also includes a lifting baffle, a vertical frame, a clamping wheel, a compression spring, and a sliding groove. A notch is provided on the movable limiting plate, a lifting baffle is provided at the bottom of the movable limiting plate, a vertical frame is provided on the lifting baffle, a clamping wheel is rotatably provided at the top of the vertical frame, the clamping wheel abuts against the bottom surface of the lifting plate, a sliding groove is provided on the lifting baffle, a compression spring is provided in the sliding groove, the upper end of the compression spring is connected to the vertical frame, and the lower end of the compression spring is connected to the inner wall of the bottom end of the notch.

[0008] Preferably, the recycling component further includes a support plate and a chip discharge port. Support plates are provided on both sides of the opening. The support plates are located on the top of the recycling hopper. The chip discharge port is provided on the support plate and communicates with the internal space of the recycling hopper. There are two support plates, which are symmetrically arranged on both sides of the planer blade.

[0009] More preferably, an inner groove is provided on one side of the lifting baffle, and the upper end of the compression spring retracts into the inner groove.

[0010] To enhance practicality, four support frames are provided, with each frame positioned at one of the four corners of the bottom of the planer.

[0011] For easy installation and fixation, the mounting bracket has an L-shaped structure. The horizontal part of the mounting bracket is fixed to the top of the planer, and the vertical electric cylinder is fixed to the horizontal end of the mounting bracket.

[0012] To facilitate smoother chip removal, the recycling hopper is tilted, with the chip removal end of the hopper facing the collection box.

[0013] To reduce costs, the collection bins are made of cloth bags.

[0014] To improve machining quality, the planer cutter uses a helical cutter shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model innovatively sets an opening at the top of the planer table and cleverly configures a recycling hopper and collection box below the opening, constructing a highly efficient automatic chip collection system. When the planer is working, the chips generated during the planing process can smoothly pass through the opening and finally fall into the collection box via the recycling hopper, thereby achieving effective collection and centralized processing of the chips. This design fundamentally solves the problem of wood chips and debris flying everywhere during the operation of traditional planers, seriously polluting the working environment, significantly improving the cleanliness of the workshop working environment, greatly reducing cleaning and maintenance costs, and eliminating potential safety hazards such as fire risks caused by chip accumulation, providing operators with a safer and healthier working environment.

[0017] 2. This utility model also innovatively introduces a collaborative working mechanism between a width-limiting component and a height-limiting component. The width-limiting component can be precisely adjusted according to the width of the wood to be processed, achieving effective lateral restraint of the wood. The height-limiting component can be adjusted according to the thickness of the wood, applying stable downward pressure to the wood through the pressure roller, ensuring that the wood remains in close contact with the planer table throughout the planing process. The collaborative action of the width-limiting and height-limiting components ensures reliable fixation of the wood during planing, eliminating the need for operators to continuously apply additional downward pressure. This greatly reduces the labor intensity of operators, significantly improves the convenience and comfort of operation, and effectively guarantees the stability of the wood planing process, thereby improving the processing efficiency and quality of the wood.

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] like Figures 1 to 7 The planer shown includes an automatic debris recovery machine, comprising:

[0028] Planer table 2, with an opening 8 on its top;

[0029] Support frame 1 is used to support the planer table 2;

[0030] Side baffle 3 is fixed to one side of the top of planer 2;

[0031] Width limiting component 5 includes a horizontal electric cylinder 501 and a movable limiting plate 502. The telescopic end of the horizontal electric cylinder 501 is connected to the movable limiting plate 502 to drive the movable limiting plate 502 to move closer to or away from the side baffle 3.

[0032] The height limiting component 4 includes a fixed frame 401, a vertical electric cylinder 402, a lifting plate 403, and a pressure roller 407. The fixed frame 401 is fixed to the top of the planer table 2, the vertical electric cylinder 402 is fixed to the fixed frame 401, the telescopic end of the vertical electric cylinder 402 is connected to the lifting plate 403, and the pressure roller 407 is rotatably mounted on the lifting plate 403 to drive the pressure roller 407 to move up and down.

[0033] The recycling component 7 includes a recycling hopper 701, a motor 702, and a planer blade 703. The recycling hopper 701 is located below the planer table 2, and the motor 702 and planer blade 703 are located on top of the planer table 2. The planer blade 703 is located at the opening 8 and is connected to the output shaft of the motor 702 to drive the planer blade 703 to rotate. The planing debris falls into the recycling hopper 701 through the opening 8.

[0034] Collection box 6 is located below recycling hopper 701 and is used to collect debris discharged from recycling hopper 701.

[0035] Compared with existing technologies, the automatic chip recovery planer proposed in this invention has significant technical advantages in achieving automatic chip recovery and stable wood compaction. Traditional planers produce chips that fly everywhere during operation, creating a harsh working environment, making cleaning and maintenance difficult, and posing safety hazards. This invention, however, constructs an efficient chip recovery system by setting an opening 8 on the planer table 2, and placing a recovery hopper 701 and a collection box 6 below the opening 8. This effectively collects the chips generated during planing, maintaining a clean working environment, reducing cleaning costs, and eliminating safety hazards. Furthermore, traditional planers rely mainly on manual compaction for wood fixation, which is labor-intensive and makes it difficult to guarantee processing accuracy. This invention, by setting a width limiting component 5 and a height limiting component 4, achieves automatic adjustment and stable compaction of the wood width and thickness, eliminating the need for excessive manual pressure, reducing the operator's labor intensity, and improving processing efficiency and quality.

[0036] As a further embodiment of this utility model, the height limiting component 4 also includes a lifting frame 404, a vertical sliding rod 405, and a buffer spring 406. The two ends of the lifting plate 403 are slidably connected to the vertical sliding rod 405. The top two ends of the lifting frame 404 are respectively fixedly connected to the two vertical sliding rods 405. The pressure roller 407 is rotatably disposed at the bottom of the lifting frame 404. The buffer spring 406 is sleeved on the vertical sliding rod 405 and located between the lifting plate 403 and the lifting frame 404.

[0037] In practice, the function of the buffer spring 406 is that when the pressure roller 407 is pressing the wood, if there is unevenness or local protrusion on the wood surface, the buffer spring 406 can provide a certain buffer stroke and buffer force, allowing the pressure roller 407 to make a slight floating in the vertical direction, thereby avoiding the pressure roller 407 from applying too much impact force to the wood surface, effectively protecting the wood surface, preventing the formation of indentations or damage, and improving the surface quality of the planing process.

[0038] By introducing components such as lifting frame 404, vertical slide bar 405 and buffer spring 406 into the height limiting component 4, the pressure roller 407 has a buffer function when pressing the wood, which can effectively adapt to the unevenness of the wood surface, avoid damage to the wood surface due to excessive pressing force, and thus better protect the wood and improve the planing quality. Its advantages are more obvious, especially when processing some wood with high surface quality requirements.

[0039] As a further embodiment of this utility model, the width limiting component 5 also includes a lifting baffle 507, a vertical frame 506, a pressing wheel 505, a compression spring 503, and a sliding groove 508. A notch is provided on the movable limiting plate 502, and the lifting baffle 507 is provided at the bottom of the movable limiting plate 502. The vertical frame 506 is provided on the lifting baffle 507, and the pressing wheel 505 is rotatably provided at the top of the vertical frame 506. The pressing wheel 505 abuts against the bottom surface of the lifting plate 403. A sliding groove 508 is provided on the lifting baffle 507, and a compression spring 503 is provided in the sliding groove 508. The upper end of the compression spring 503 is connected to the vertical frame 506, and the lower end of the compression spring 503 is connected to the inner wall of the bottom end of the notch.

[0040] In practical implementation, the function of the lifting baffle 507 is that when the pressure roller 407 is raised, the lifting baffle 507 also rises, providing sufficient space for the feeding and movement of wood; while when the pressure roller 407 presses the wood down, the lifting baffle 507 descends synchronously, effectively blocking the notch on the moving limiting plate 502, thereby preventing debris from splashing out from the notch and improving the debris recycling effect. To achieve the linkage between the lifting movement of the lifting baffle 507 and the lifting movement of the pressure roller 407, this invention designs a sophisticated linkage mechanism. This linkage mechanism mainly includes components such as a vertical frame 506, a pressing wheel 505, a compression spring 503, and a sliding groove 508. The vertical frame 506 is fixed to the top of the lifting baffle 507, serving as the main supporting component of the linkage mechanism. The pressing wheel 505 is rotatably mounted on the top of the vertical frame 506 and always maintains contact with the bottom surface of the lifting plate 403 in the height limiting component 4. A compression spring 503 is disposed within a groove 508 of the lifting baffle 507, with its upper end connected to the vertical frame 506 and its lower end connected to the inner wall of the bottom of the groove 508. The groove 508 is disposed on the lifting baffle 507 to provide guidance and constraint for the movement of the compression spring 503 and the vertical frame 506.

[0041] As a further embodiment of this utility model, the recycling component 7 also includes a support plate 704 and a chip discharge port 705. Support plates 704 are provided on both sides of the opening 8. The support plates 704 are located on the top of the recycling hopper 701. The chip discharge port 705 is provided on the support plate 704 and communicates with the internal space of the recycling hopper 701. There are two support plates 704, and the two support plates 704 are symmetrically arranged on both sides of the planer blade 703.

[0042] In practice, by adding components such as a tray 704 and a chip discharge port 705 to the recycling component 7, the chips generated by planing can fall more smoothly and accurately into the recycling hopper 701 under the guidance of the tray 704, effectively avoiding the accumulation and splashing of chips around the opening 8.

[0043] As a further embodiment of this utility model, an inner groove 504 is provided on one side of the lifting baffle 507, and the upper end of the compression spring 503 is retracted into the inner groove 504.

[0044] In specific implementation, by setting an inner groove 504 on the lifting baffle 507 and retracting the upper end of the compression spring 503 into the inner groove 504, the compression spring 503 can maintain a stable posture during operation, avoiding bending or displacement. This effectively improves the working stability and service life of the compression spring 503, thereby ensuring the reliability and accuracy of the lifting action of the lifting baffle 507. Optimizing the installation structure of the compression spring 503 further enhances the overall reliability and durability of the width limiting component 5, enabling the planer to maintain stable performance and good working condition even during long-term use.

[0045] As a further embodiment of this utility model, there are four support frames 1, which are respectively set at the four corners of the bottom of the planer table 2.

[0046] In practice, the support frame 1 provides balanced and stable support for the planer table 2, effectively improving the overall stability and reliability of the planer.

[0047] As a further embodiment of this utility model, the fixing frame 401 has an L-shaped structure, the horizontal part of the fixing frame 401 is fixed to the top of the planer table 2, and the vertical electric cylinder 402 is fixed to the horizontal end of the fixing frame 401.

[0048] In practical implementation, by designing the fixed frame 401 as an L-shaped structure and installing the vertical electric cylinder 402 on the horizontal end of the fixed frame 401, the installation of the vertical electric cylinder 402 is made simpler and faster. At the same time, it ensures that the fixed frame 401 has sufficient strength and stability to reliably support the working load of the vertical electric cylinder 402 and the pressure roller 407, ensuring the stable operation of the height limiting component 4. Through the optimization of the structure of the fixed frame 401, the structural compactness and installation convenience of the height limiting component 4 are further improved, contributing to the overall structural optimization and performance improvement of the planer.

[0049] As a further embodiment of this utility model, the recycling hopper 701 is inclined, and the chip discharge end of the recycling hopper 701 is directed toward the collection box 6.

[0050] In practice, the tilted installation of the recycling bucket 701 can be achieved through various structures. For example, a tilt angle adjustment mechanism can be set on the mounting bracket of the recycling bucket 701, or the body of the recycling bucket 701 can be designed as a tilted shape and fixed below the planer 2.

[0051] As a further embodiment of this utility model, the collection box 6 is a cloth bag.

[0052] In practice, the opening of the bag-type collection box 6 can be sealed with a drawstring, zipper, or Velcro to prevent the collected debris from scattering during handling or dumping. To facilitate the replacement and cleaning of the bag-type collection box 6, its opening can be designed as a detachable structure, allowing users to easily remove the bag from the recycling hopper 701 for dumping or washing.

[0053] As a further embodiment of this utility model, the planer 703 is a spiral cutter shaft.

[0054] In practice, the material and structure of the blades of the spiral cutter shaft can be selected and designed according to different processing needs. For example, the blades can be made of wear-resistant materials such as cemented carbide or high-speed steel, and the shape of the blades can be designed as rectangular, rhomboid, or arc to adapt to the processing of different types and hardness of wood.

[0055] Working principle of this utility model:

[0056] When processing wood using the automatic chip recovery planer of this invention, the operator first adjusts the width limiting component 5 and the height limiting component 4 according to the width and thickness of the wood to be processed, places the wood on the planer table 2, with one side abutting against the movable limiting plate 502 and the top positioned below the pressure roller 407. Then, the motor 702 in the recovery component 7 is started, driving the planer blade 703 to rotate at high speed, beginning the planing process. During planing, the planer blade 703 cuts the bottom surface of the wood, smoothing the surface. The planing chips, guided by the side baffle 3 and the movable limiting plate 502, and under their own weight, fall through the opening 8 at the top of the planer table 2 into the recovery hopper 701 located below. The recovery hopper 701 collects and guides the chips, finally discharging them into the collection box 6 below for centralized storage. After processing, the operator turns off the planer, removes the processed wood, and periodically cleans the debris from collection box 6 to keep the equipment clean and running normally. Throughout the processing, debris is effectively controlled within the recycling system, preventing it from scattering everywhere. The working environment remains clean, and operators no longer need to exert effort to compress the wood, making operation easier and more efficient.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
