Description

Technical Field

[0001] This utility model relates to the field of woodworking panel saw technology, specifically to a waste collection structure for a woodworking panel saw. Background Technology

[0002] CNC panel saws are essential equipment in the wood processing industry, mainly composed of a processing table, a moving frame, a tool holder, and cutter heads. The processing table serves as the load-bearing component, holding the wood workpiece to be processed. The moving frame moves related components along a preset trajectory, adjusting the processing position. The tool holder fixes and supports the cutter heads, which are the executing components that directly cut, groove, and perform other processing operations on the wood. High-speed rotation completes precise processing of the wood. During the processing of wood with a CNC panel saw, the resulting wood chips need to be collected and disposed of promptly to prevent wood chip splashing, which could pollute the working environment, affect processing accuracy, and harm the health of operators. Currently, the industry typically uses dust collection devices to cover the wood chips in the processing area and external vacuum cleaners to remove and collect them.

[0003] Existing dust collection devices generally adopt a ring-shaped brush design at the bottom, which uses the brush bristles to surround and cover the cutting head of the wood to prevent the wood chips from splashing and spreading during processing. However, in actual processing, when it is necessary to process a deeper part of the workpiece, the brush needs to descend synchronously with the cutting head. During this process, the brush will be squeezed against the surface of the workpiece, and its bristles are prone to lying down, tilting, or even locally stacking.

[0004] The problem of bristle deformation may cause gaps in the covering area of ​​the dust collection device, causing some wood chips to overflow from the gaps, which greatly reduces the dust collection efficiency. At the same time, continuous squeezing and friction will aggravate the wear of the brush, causing problems such as bristle bending and breakage. This not only shortens the service life of the brush, but also further affects the dust covering effect, making it difficult to meet the needs of efficient and stable waste collection. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a waste collection structure for a woodworking panel saw. This structure has the advantage of continuously adhering to the surface of the workpiece, improving the efficiency of waste collection. It solves the problem that in existing CNC panel saws, during wood processing, a dust collection device is typically used to cover the wood chips generated during processing, and an external dust collection device is used to suck them away. Existing dust collection devices generally use a ring-shaped brush design at the bottom to cover the cutting head and prevent wood chips from flying during processing. However, when processing deeper parts of the workpiece, the brush needs to descend synchronously with the cutting head. During this process, the brush is compressed, and its bristles tend to lie flat or tilt outwards, or even pile up locally. This may create gaps in the covered area, reducing dust collection efficiency and accelerating brush wear, causing bristle bending or breakage, thus affecting the dust covering effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste collection structure for a woodworking panel saw, comprising a processing table, a movable frame, a tool holder, and a tool head, wherein a waste collection mechanism is provided on the front side of the tool holder. The waste collection mechanism includes a support plate, the top of which is fixedly connected to the knife holder, and a dust collection assembly is provided at the bottom of the support plate. The outer surface of the dust collection component is evenly distributed with multiple bonding components, and the bottom of the dust collection component is provided with a movable component.

[0007] As a preferred embodiment of this utility model, the dust collection assembly includes a protective plate, an air extraction port is fixedly connected to the top of the protective plate, a connecting hose is fixedly connected to the top of the air extraction port, a telescopic hose is fixedly connected to the bottom of the protective plate, and a support block is fixedly connected to the curved surface of the protective plate.

[0008] In a preferred embodiment of this invention, the protective plate is sleeved on the surface of the blade, and the number of the support blocks is multiple, and they are evenly distributed in a ring array.

[0009] In a preferred embodiment of this invention, the bonding component includes a connecting block, a sliding column is fixedly connected to the top of the connecting block, a limit block is provided at the top of the sliding column, a spring is sleeved on the surface of the sliding column, and the top and bottom of the spring are fixedly connected to the support block and the connecting block, respectively.

[0010] In a preferred embodiment of this invention, the top of the sliding column penetrates the support block and extends to the outside of the support block, where it is fixedly connected to the limiting block, and is slidably connected to the penetration point of the support block via a linear bearing.

[0011] As a preferred embodiment of the present invention, the movable component includes a housing, the top of which is fixedly connected to a telescopic hose, a through hole at the bottom of which is provided, and a ball bearing is provided in the inner cavity of the housing. The side of the ball bearing closest to the inner wall of the housing contacts the inner wall of the housing, and the bottom of the curved surface passes through the through hole and extends to the outer side of the housing.

[0012] In a preferred embodiment of this invention, the number of balls is multiple and they are evenly distributed in a ring array, and the number of through holes is multiple, with a diameter smaller than that of the balls.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem of existing CNC cutting machines using a waste collection mechanism. In the process of wood processing, existing dust collection devices typically use a ring-shaped brush design at the bottom to cover the cutting head and prevent wood chips from flying during processing. However, when processing deeper parts of the workpiece, the brush needs to descend synchronously with the cutting head. During this process, the brush is compressed, causing the bristles to bend outwards, tilt, or even pile up locally. This can create gaps in the covered area, reducing dust collection efficiency and accelerating brush wear, leading to bristle bending or breakage, thus affecting the dust coverage. This new invention achieves the effect of continuously adhering to the surface of the workpiece during processing, effectively covering and collecting dust, reducing wear on the contact points with the workpiece, and extending the service life of the equipment.

[0014] 2. By setting up a dust collection component, this utility model can cover the dust generated during the processing and collect it by external dust collection equipment.

[0015] 3. By setting up a bonding component, this utility model can ensure that the dust collection component can continuously adhere to the surface of the workpiece during the downward processing and moving cutting process of the cutter head, thus avoiding dust splashing.

[0016] 4. By setting a moving component, this utility model can reduce wear between the dust collection component and the workpiece during the movement of the dust collection component. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0023] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a waste collection structure for a woodworking panel saw, including a processing table 1, a movable frame 2, a cutter holder 3, and a cutter head 4. A waste collection mechanism 5 is provided on the front side of the cutter holder 3. The waste collection mechanism 5 includes a support plate 51, the top of which is fixedly connected to the knife holder 3, and a dust collection assembly 52 is provided at the bottom of the support plate 51. Multiple bonding components 53 are evenly distributed on the outer surface of the dust collection component 52, and a moving component 54 is provided at the bottom of the dust collection component 52.

[0024] Specifically, by setting up the dust collection component 52, the dust generated during the processing can be coated and collected by an external dust collection device; By setting the bonding component 53, the dust collection component 52 can be continuously bonded to the surface of the workpiece during the downward processing and moving cutting of the cutter head 4, thus preventing dust from splashing. By setting the moving component 54, wear between the dust collection component 52 and the workpiece can be reduced during the movement of the dust collection component 52. By setting the support plate 51, the dust collection component 52 can be supported, so that it can rise or move synchronously with the cutter holder 3 and the cutter head 4.

[0025] Furthermore, during operation, the waste collection mechanism 5 moves synchronously with the movement of the tool holder 3 and the tool head 4. The support plate 51 provides stable support for the dust collection component 52, which covers the processing area of ​​the tool head 4. The fitting component 53 ensures that the dust collection component 52 is in close contact with the workpiece surface, while the moving component 54 reduces frictional wear between the dust collection component 52 and the workpiece as the dust collection component 52 moves with the tool head 4, thus completing waste collection in conjunction with external dust collection equipment.

[0026] Example 2 In the second embodiment of this utility model, the dust collection assembly 52 includes a protective plate 521, an air extraction port 522 is fixedly connected to the top of the protective plate 521, a connecting hose 523 is fixedly connected to the top of the air extraction port 522, a telescopic hose 524 is fixedly connected to the bottom of the protective plate 521, and a support block 525 is fixedly connected to the curved surface of the protective plate 521.

[0027] The protective plate 521 is fitted onto the surface of the cutter head 4, and there are multiple support blocks 525, which are evenly distributed in a ring array.

[0028] Specifically, by setting up a protective plate 521 and a telescopic hose 524, the protective plate 521 and the telescopic hose 524 form a ring-shaped covering on the processing area of ​​the cutter head 4, effectively blocking sawdust and dust from splashing. The telescopic hose 524 can adapt to the height changes during the lifting and lowering process of the cutter head 4. By setting an air extraction port 522 and a connecting hose 523, the air extraction port 522 and the connecting hose 523 can work with an external vacuum cleaner to quickly remove waste from the covered area. By setting a support block 525, the bonding component 53 can be supported.

[0029] Furthermore, the protective plate 521 is fitted onto the surface of the cutter head 4 and moves synchronously with the cutter holder 3 and the cutter head 4 via the support plate 51. The sawdust and dust generated during processing are confined within the enclosed space formed by the protective plate 521. One end of the connecting hose 523 is connected to the air extraction port 522, and the other end is connected to a vacuum cleaner. Under the negative pressure of the vacuum cleaner, the waste material in the enclosed space is sucked into the external vacuum cleaner through the air extraction port 522 and the connecting hose 523. The telescopic hose 524 connects the bottom of the protective plate 521 to the moving component 54 and can extend and retract with the raising and lowering of the cutter head 4.

[0030] Example 3 In the third embodiment of this utility model, the bonding component 53 includes a connecting block 531, a sliding column 532 is fixedly connected to the top of the connecting block 531, a limit block 533 is provided on the top of the sliding column 532, and a spring 534 is sleeved on the surface of the sliding column 532. The top and bottom of the spring 534 are fixedly connected to the support block 525 and the connecting block 531, respectively.

[0031] The top of the sliding column 532 passes through the support block 525 and extends to the outside of the support block 525 to be fixedly connected to the limiting block 533, and is slidably connected to the through-hole of the support block 525 through a linear bearing.

[0032] Specifically, by setting spring 534, the elastic force of spring 534 ensures that the moving component 54 always remains in contact with the workpiece surface, so that even when the cutter head 4 is rising and falling, it can continuously cover the dust and ensure dust collection efficiency. By setting the sliding column 532, the spring 534 can be limited, and the linear bearing reduces the friction between the sliding column 532 and the support block 525. By setting the limiting block 533, the sliding column 532 can be prevented from falling off the support block 525.

[0033] Furthermore, when the cutting head 4 descends for processing, the moving component 54 contacts and is compressed against the workpiece surface. The connecting block 531 pushes the sliding column 532 upward, and the sliding column 532 slides upward along the linear bearing within the support block 525. At the same time, the spring 534 is compressed and generates a reverse elastic force. Under the action of the elastic force, the connecting block 531 drives the moving component 54 to always press tightly against the workpiece surface and maintain a close fit. When the cutting head 4 rises, the spring 534 returns to its original position and extends, pushing the sliding column 532 downward so that the moving component 54 continues to maintain contact with the workpiece surface.

[0034] Example 4 In the fourth embodiment of this utility model, the movable component 54 includes a housing 541. The top of the housing 541 is fixedly connected to the telescopic hose 524. A through hole 542 is provided at the bottom of the housing 541. A ball bearing 543 is provided in the inner cavity of the housing 541. The side of the ball bearing 543 near the inner wall of the housing 541 contacts the inner wall of the housing 541, and the bottom of the curved surface passes through the through hole 542 and extends to the outer side of the housing 541.

[0035] There are multiple balls 543, which are evenly distributed in a ring array. There are multiple through holes 542, and their diameter is smaller than that of the balls 543.

[0036] Specifically, by setting the ball bearings 543, the sliding friction between the dust collection component 52 and the workpiece surface is converted into the rolling friction of the ball bearings 543, which greatly reduces the wear of the contact parts and extends the service life of the equipment. The multiple ring-shaped ball bearings 543 can evenly distribute the pressure and ensure the stability of the contact between the moving component 54 and the workpiece surface. By providing a housing 541 and a through hole 542, the housing 541 can accommodate and limit the ball 543, while the diameter of the through hole 542 is smaller than the diameter of the ball 543 to prevent the ball 543 from falling out of the housing 541, while ensuring that the bottom of the ball 543 is in effective contact with the workpiece surface.

[0037] Furthermore, the housing 541 is connected to the protective plate 521 of the dust collection assembly 52 via a telescopic hose 524 and moves synchronously with the protective plate 521. During processing, the ball bearing 543 at the bottom of the housing 541 contacts the workpiece surface. When the cutter head 4 moves the dust collection assembly 52, the ball bearing 543 rolls on the workpiece surface, causing the housing 541 to slide synchronously with the direction of movement of the cutter head 4. The ball bearing 543 can rotate freely in the inner cavity of the housing 541. By rolling, friction loss with the workpiece surface is reduced. The through hole 542 limits the ball bearing 543, preventing the ball bearing 543 from detaching from the housing 541, while ensuring that the bottom of the ball bearing 543 is always in contact with the workpiece surface, and achieving continuous adhesion with the elasticity of the bonding assembly 53.

[0038] Working principle: When the waste collection mechanism 5 of the woodworking cutting machine is working, the waste collection mechanism 5 is fixedly connected to the cutter holder 3 through the support plate 51, and moves synchronously with the cutter holder 3 and the cutter head 4. After processing begins, the protective plate 521 of the dust collection assembly 52 is fitted onto the surface of the cutter head 4, and forms a ring-shaped covering on the processing area of ​​the cutter head 4 through the telescopic hose 524 to prevent sawdust and dust from splashing. The air extraction port 522 at the top of the protective plate 521 is connected to an external dust collection device through the connecting hose 523. Under negative pressure, the waste generated during processing is sucked into the air extraction port 522 and transported to the external dust collection device for collection through the connecting hose 523. When the cutter head 4 descends to process or move for cutting, the ball 543 of the moving component 54 contacts and is squeezed against the workpiece surface. The connecting block 531 pushes the sliding column 532 to slide upward along the linear bearing in the support block 525. The spring 534 is compressed to generate elastic force. The elastic force is transmitted to the ball 543 through the connecting block 531 and the housing 541, so that the ball 543 always presses tightly against the workpiece surface, avoiding a large gap between the telescopic hose 524 and the workpiece, and preventing dust from spilling out. During the movement of the cutter head 4, the balls 543 of the moving component 54 roll on the workpiece surface, converting sliding friction into rolling friction, reducing wear on the workpiece surface. At the same time, the multiple annularly distributed balls 543 ensure the stability of the movement process. The telescopic hose 524 extends and retracts flexibly with the rise and fall of the cutter head 4, ensuring the sealing of the enclosed space. When the cutter head 4 rises, the spring 534 of the contact component 53 returns to its original position and extends, pushing the sliding column 532 downward to keep the moving component 54 in continuous contact with the workpiece.

[0039] In summary, by setting up the waste collection mechanism 5, the equipment can continuously adhere to the surface of the workpiece during processing, cover and collect the dust generated during processing, reduce wear on the parts in contact with the workpiece, and extend the service life of the equipment.
