Description

Technical Field

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

[0002] With the widespread application of engineered wood products in furniture manufacturing, construction and decoration industries, traditional general-purpose circular saws can no longer meet the demands of modern processing technology in terms of processing precision and production efficiency. The market has gradually introduced panel saws to improve the precision and efficiency of wood cutting. However, the sawdust and dust generated during wood cutting have impacted the working environment and the health of operators. After the machine finishes cutting the boards, sawdust and dust remain on the worktable.

[0003] The current structural design uses a pressure beam suction port for dust collection, but because the distance between the suction port and the workbench is far, and the pressure beam and the workbench are not completely sealed, the dust collection effect is not satisfactory. Utility Model Content

[0004] The purpose of this invention is to provide a dust collection structure for a panel saw that can quickly and effectively remove wood chips and dust accumulated on the workbench, improve the dust removal efficiency of the panel saw, and prevent particulate matter from damaging the surface of the board.

The workbench has a saw kerf and several air outlets. The straightedge has a first dust collection port, and the pressure beam has a second dust collection port. Some of the air outlets are equipped with pneumatic floats, and the remaining air outlets are equipped with air outlet components. The air outlet components are directed towards the first dust collection port.

[0008] In some embodiments, the air outlet assembly includes an air duct assembly and a flexible switch, the air duct assembly having an air inlet, an air duct and an air outlet that are interconnected, and the air duct assembly is disposed on the mounting hole;

[0009] The elastic switch is located on the air duct assembly. When the elastic switch is in a compressed state, the air outlet is connected to the air duct; when the elastic switch is in a relaxed state, the air outlet is closed.

[0011] In some embodiments, the resilient switch includes a ball and a spring, with a first end of the spring connected to the ball and a second end connected to the bottom wall of the lower valve sleeve. The ball is embedded in the air outlet, and the diameter of the ball is larger than the diameter of the air outlet, so that a portion of the ball protrudes outside the air outlet.

[0012] The inner diameter of the lower valve sleeve is larger than the diameter of the ball.

[0013] In some embodiments, the upper valve sleeve and the lower valve sleeve are snap-fitted together.

[0029] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0032] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Woodworking sawing equipment generates a significant amount of wood chips and dust during sawing, which are dispersed outwards. If the dust collection system is ineffective, this accumulation of chips and dust can damage bearings, cylinders, motors, and other components, impacting equipment performance, lifespan, and stability. Furthermore, wood dust permeating the workshop can harm the health of operators. To improve the dust collection efficiency of panel saws, this invention provides a dust extraction structure that quickly and effectively removes accumulated wood dust from the workbench, enhancing dust collection efficiency and preventing particulate matter from damaging the surface of the wood panels.

[0034] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0035] Figure 1 This is a schematic diagram of the dust collection structure of the panel saw 1 shown in this embodiment of the present invention.

[0036] like Figures 1 to 5 As shown in the figure, the present invention provides a dust collection structure for a panel saw, including a workbench 2, a straightedge 3, and a pressure beam 4 on the panel saw 1. The workbench 2 has a saw kerf 20 and a plurality of air outlets 21 located on both sides of the saw kerf 20. The straightedge 3 is provided with a first dust collection port 30, and the pressure beam 4 is provided with a second dust collection port 40. Some of the air outlets 21 are provided with pneumatic floats, and the remaining air outlets 21 are provided with air outlet components 22. The air outlet components 22 are directed towards the first dust collection port 30.

[0037] Specifically, the workbench 2 on the panel saw 1 is used to support the board material. The air outlet 21 on the workbench 2 is used to install pneumatic floats or an air outlet assembly 22. The pneumatic floats are used to roll and contact the board material, allowing the pusher device of the panel saw 1 to push the board material onto the workbench 2 without damage. The air outlet assembly 22 is used to exhaust air to clean sawdust and dust from the workbench 2. The straightedge 3 is located below the pressure beam 4 and at the end of the saw kerf 20. The straightedge 3 is designed as a hollow structure and has multiple first suction ports 30 on the side facing the board material. Both the first suction ports 30 of the straightedge 3 and the second suction ports 40 of the pressure beam 4 are connected to suction devices, such as centrifugal fans. The straightedge 3 serves as a reference surface during the board material sawing process, with one side of the board material abutting against the straightedge 3 during sawing. In this embodiment, to improve the dust removal efficiency of the panel saw 1 and prevent the accumulated wood dust on the workbench 2 from affecting the rolling performance of the pneumatic float or causing large wood chips to scratch the board, part of the air outlet 21 is replaced with an air outlet assembly 22, which is connected to an air outlet device, such as a blower. When the board enters the workbench 2 and abuts against the guide ruler 3, the pressure beam 4 descends to press the board, forming an air channel between the board and the workbench 2. The saw blade travels along the kerf 20 to cut the board, and the air outlet assembly 22 blows the wood dust in the air channel toward the first suction port 30. Because the gap between the board and the workbench is small, the airflow has a relatively strong force to move the wood dust when flowing in the air channel. After the wood dust is blown to the first suction port 30 of the guide ruler 3, it is sucked into the cavity inside the guide ruler 3 under negative pressure and collected by a collection device. The pressure beam 3 is also hollow to facilitate the sawing channel of the sawing mechanism. After the pressure beam 4 descends, it forms a relatively sealed space with the upper surface of the board. During the sawing process, the suction device performs negative pressure suction through the second suction port 40 on the pressure beam 4. In some embodiments, in order to ensure that the original air outlet 21 can achieve the suspension design of the board, the air outlet component 22 can be alternately set with the pneumatic float, or the air outlet 21 closest to both sides of the saw kerf 20 can be replaced with the air outlet component 22. The air outlet direction of the air outlet component 22 is towards the first suction port 30 of the guide ruler 3. When the saw blade moves to cut the board, the air outlet component 22 can blow the wood dust towards the first suction port 30 and form an air wall on both sides of the saw kerf 20 to prevent the wood dust from splashing or being blown to a farther place. With this setting, the dust collection effect can be improved and the frequency of manual cleaning can be reduced.

[0038] In this embodiment, the working process of the air outlet assembly 22, the first dust suction port 30, and the second dust suction port 40 is as follows: During the sawing process of the board, wood dust splashes and escapes from the saw kerf 20, the saw blade, and its surrounding area. At this time, the air outlet assembly 22, located on the workbench, blows the wood dust between the board and the workbench towards the first dust suction port 30. Subsequently, the first dust suction port 30 and the second dust suction port 40, with the aid of a suction device, remove the accumulated wood dust on the workbench. In addition, the design of the air outlet assembly 22 takes into account the distribution and direction of the airflow, ensuring that the dust can be effectively guided to the dust suction port. The combined suction of the first dust suction port 30 and the second dust suction port 40 can better cover the areas on the workbench 2 where a large amount of dust may accumulate, ensuring the cleaning effect of wood dust.

[0039] In a preferred embodiment, a plurality of air outlet components 22 are arranged side by side on both sides of the saw kerf 20 along the length of the saw kerf 20.

[0040] The workbench 2 has an air cavity and several mounting holes communicating with the air cavity, and the air outlet assembly 22 is disposed on the mounting holes.

[0041] Based on the above specific embodiments, the air outlet assembly 22 includes an air duct assembly 220 and a flexible switch 221. The air duct assembly 220 has an air inlet, an air duct and an air outlet that are interconnected. The air duct assembly 220 is disposed on the mounting hole.

[0042] The elastic switch 221 is mounted on the air duct assembly 220. When the elastic switch 221 is in a compressed state, the air outlet is connected to the air duct; when the elastic switch 221 is in a relaxed state, the air outlet is closed. After the board enters the workbench, the board presses down on the elastic switch 221, compressing it and connecting the air outlet to the air duct, thus allowing air to flow. When the elastic switch 221 is not in contact with the board, it is in a relaxed state, blocking the air outlet.

[0043] Furthermore, the air duct assembly 220 includes an upper valve sleeve 2200 and a lower valve sleeve 2201. The lower valve sleeve 2201 is embedded in the upper valve sleeve 2200. The upper valve sleeve 2200 is snap-fitted to the workbench 2. The upper valve sleeve 2200 has the air outlet. The outer periphery of the lower valve sleeve 2201 is provided with a hollow structure, which is the air inlet. The elastic switch 221 is disposed in the lower valve sleeve 2201.

[0044] The upper valve sleeve 2200 and the lower valve sleeve 2201 are connected by snap-fits, and the upper valve sleeve 2200 is also connected to the worktable 2 by snap-fits. The upper valve sleeve 2200 has snap-fits on its outer periphery and grooves on its inner sidewall. The inner sidewall of the mounting hole is designed with a slot for inserting and engaging with the snap-fits, while the outer periphery of the lower valve sleeve 2201 has a hook for engaging with the groove. After the upper valve sleeve 2200 is snapped into the slot by the snap-fits, its rotation angle can be manually adjusted. The lower valve sleeve 2201 is fixed after engaging with the upper valve sleeve 2200. Both the upper valve sleeve 2200 and the lower valve sleeve 2201 have a cylindrical structure. One end of the upper valve sleeve 2200 is open, and the other end has an air outlet. The diameter of the air outlet is smaller than the inner diameter of the upper valve sleeve 2200. The lower valve sleeve 2201 fits into the upper valve sleeve 2200. One end of the lower valve sleeve facing the air outlet is also open, while the other end can be a sealed surface or have a corresponding perforated structure. The flexible switch 221 is housed within the lower valve sleeve 2201, with its end abutting against the end face of the lower valve sleeve 2201. The upper valve sleeve 2200 and the lower valve sleeve 2201 together define an air outlet cavity for accommodating the flexible switch 221. When no material is placed on the workbench 2, the flexible switch 221 is in an expanded state, closing the air outlet. When the flexible switch 221 deforms due to the weight of the material, it contracts, opening the air outlet and allowing air to escape.

[0045] Furthermore, the upper valve sleeve 2200 and the lower valve sleeve 2201 can be manufactured using an integrated injection molding process. In a preferred embodiment, nylon or polycarbonate is selected as the manufacturing material. This type of structure is particularly suitable for high-strength assembly requirements. Using recycled materials, the material can be directly injection molded on an injection molding machine, enabling the recycling of recycled plastics.

[0046] To improve the durability of the resilient switch 221, the resilient switch 221 includes a ball 2210 and a spring 2211. The first end of the spring 2211 is connected to the ball 2210, and the second end is connected to the bottom wall of the lower valve sleeve 2201. The ball 2210 is embedded in the air outlet, and the diameter of the ball 2210 is larger than the diameter of the air outlet, so that a portion of the ball 2210 protrudes outside the air outlet. The inner diameter of the lower valve sleeve 2201 is larger than the diameter of the ball 2210. The ball 2210 can be made of metal or plastic. In some embodiments, the ball 2210 can be made of steel ball or nylon ball. When steel ball is used, the spring 2211 is welded to the steel ball. When nylon ball is used, the spring 2211 and the nylon ball can be integrated through injection molding to improve the connection strength between the nylon ball and the spring 2211.

[0047] In another feasible solution, the elastic switch 221 can also be a magnetic switch. Specifically, the magnetic switch includes an iron ball, a spring, a coil, and an iron core. The two ends of the spring are connected to the iron ball and the iron core, respectively. The coil is wound around the iron core, which is installed on the bottom wall of the lower valve sleeve. Both the iron ball and the spring are located inside the lower valve sleeve. The magnetic switch is controlled electronically to close or open the air outlet. Preferably, to achieve automated design of the magnetic switch, save energy consumption, and adapt it to different sizes of sheet metal, ensuring that the air outlet structure of the un-saved area can close during the sawing process and not participate in the blowing, the magnetic switch is also connected to a controller and several through-beam photoelectric sensors. Several detection holes adjacent to the air duct assembly 220 are provided on the air-floating platform 2, and the detection holes are opposite to the pressure beam 4. The transmitting end of the through-beam photoelectric sensor is set on the detection hole, and the receiving end of the through-beam photoelectric sensor is set on the pressure beam 4. When the board is fed to the sawing position, the pressure beam 4 mechanism descends and presses the board. Part of the receiving end of the through-beam photoelectric sensor is blocked by the board, preventing it from receiving the signal from the transmitting end. After the controller obtains the signal information from the through-beam photoelectric sensor, it controls the corresponding magnetic switch to de-energize, causing the spring to reset and the iron ball to rise and block the air duct between the lower valve sleeve 2201 and the upper valve sleeve 2200, thereby shutting off the air outlet of the air duct assembly 220. This setting reduces the working pressure of the air outlet device, decreases the air volume of the panel saw 1, and thus saves energy consumption.

[0048] Based on the above specific embodiments, the air outlet assembly 22 further includes an air guide hood 222, which is located above the air outlet. The air guide hood 222 is connected to the elastic switch 221. The air guide hood 222 has a chamber for receiving the air duct assembly 220. The air guide hood 222 can slide up and down relative to the air duct assembly 220. One side of the air guide hood 222 is provided with an air guide outlet facing the first dust suction port 30. The air guide hood 222 is a hollow cylindrical structure with one end open and the other end closed. A guide outlet is provided on the outside of the closed end. The open end of the air guide hood 222 is embedded in the upper valve sleeve. The elastic switch 221 is connected to the inner wall of the closed end. Under this configuration, the air guide hood 222 slides with the elastic switch 221. The interior of the air guide hood 2222 has an arc-shaped air guide surface for guiding airflow, which faces the first dust suction port 30.

[0049] It is understood that the suction device and the exhaust device are existing technologies and are well known to those skilled in the art, so they will not be described in detail here.

[0050] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
