Description

Technical Field

[0001] This application relates to the technical field of wood chip collection equipment for wooden door drilling, and in particular to a wood chip collection device for a wooden door drilling and forming production line. Background Technology

[0002] During the drilling process of wooden doors, the high-speed rotating drill bit rubs and cuts against the wood material, generating a large amount of wood chips and dust. Each standard wooden door produced can generate a large amount of chips. If these wood chips are not collected in a timely and effective manner, they can cause multiple problems. Scattered chips accumulate on the workbench and conveyor line, causing the wooden door positioning to be off. Dust floats in the workshop air, and long-term exposure can lead to pneumoconiosis and respiratory diseases among operators. Wood chips are flammable materials, and excessive accumulation poses a fire hazard. Therefore, an efficient wood chip dust collection system has become an essential facility for automated wooden door production lines. Its dust collection efficiency directly determines the production accuracy, the environmental protection level of the workshop, and the operating costs.

[0003] With tightening environmental policies and increasing demand for automated production, the industry is gradually promoting semi-enclosed dust collection systems that use dust hoods, pipes, and dust collectors. The core design involves setting up fixed or adjustable dust hoods around the drill bit of a drilling machine, and using negative pressure from a fan to draw sawdust into the dust collection pipes.

[0004] Regarding the aforementioned technologies, the inventors discovered that poor adaptability of the vacuum cleaner hoods leads to widespread gaps. Wooden doors vary greatly in size, while vacuum cleaner hoods are mostly fixed in size or only adjustable within a small range, making it impossible for them to completely fit the surface of the wooden door. Gaps form between the vacuum cleaner hood and the wooden door, and wood chips generated by high-speed drilling escape through these gaps under the influence of airflow. This results in low dust collection efficiency, requiring frequent sweeping of the workshop floor, and the problem of debris accumulation remains unresolved. Utility Model Content

[0005] To overcome the shortcomings of existing dust collection hoods, such as poor adaptability leading to gaps, the large differences in wooden door specifications, and the fact that most dust collection hoods are of fixed size or can only be adjusted within a small range, resulting in gaps between the dust collection hood and the wooden door, and the wood chips generated by high-speed drilling escaping through these gaps under the influence of airflow, resulting in low dust collection efficiency, frequent cleaning of the workshop floor, and unresolved chip accumulation problem, this application provides a wood chip collection device for a wooden door drilling and forming production line.

[0006] The sawdust collection device for a wooden door drilling and forming production line provided in this application adopts the following technical solution: A sawdust collection device for a wooden door drilling and forming production line includes a drilling device, a dust collection component, a suction pipe, and a collection component. The upper part of the drilling device is adjustablely equipped with a drilling arm, and a drilling motor is vertically fixed on the bottom surface of the drilling arm. The dust collection component includes a sleeve, a corrugated pipe, and a lower ring plate. The sleeve is vertically slidably fitted onto the drilling motor of the drilling arm, and a downward pressure spring is vertically fixed on the top surface of the sleeve, with the top end of the downward pressure spring fixed on the bottom surface of the drilling arm. The corrugated pipe is vertically connected and fixed to the bottom surface of the sleeve, and a lower ring plate is horizontally fixed on the bottom surface of the corrugated pipe. A rubber ring is vertically fixed on the bottom surface of the lower ring plate. A suction shell is connected and fixed to the outer wall of the sleeve, and a suction pipe is connected and fixed to one end of the suction shell. A bend is connected and fixed to the other end of the suction pipe, and a collection component is vertically connected and fixed to the bottom end of the bend.

[0007] By adopting the above technical solutions, and by setting up a drilling arm and a drilling motor, the drilling arm can be adjusted up and down according to actual processing needs, allowing the drilling motor to adapt to the processing requirements of wooden doors of different heights, thus improving the applicability and flexibility of the drilling equipment. Since the drilling motor is vertically fixed to the bottom of the drilling arm, the drilling motor remains stable during up and down adjustment, avoiding vibration or displacement caused by the adjustment process, thereby ensuring the accuracy and stability of the drilling. By setting up a dust collection component, a device composed of a sleeve and a downward pressure spring not only stably supports the dust collection component during the drilling process, but also ensures that the vertical position of the dust collection component changes synchronously when the drilling arm moves up and down, ensuring the stability of the dust collection effect. The corrugated pipe effectively improves the flexibility of the pipeline, allowing the vacuum cleaner to flexibly adapt to changes in angle and height during drilling, avoiding blockages or inconvenience caused by fixed pipelines. The combined use of the lower ring plate and the rubber ring enhances the adsorption force of sawdust at the drilling location, and the softness of the rubber ring better fills the gaps at the drilling location, further improving the dust collection effect. By designing the suction housing and suction pipe, a closed suction duct system is formed. This not only ensures the stability and efficiency of the suction effect but also reduces air resistance, resulting in more uniform suction between the suction and collection components and improving the efficiency of sawdust collection. The introduction of the curved pipe makes the airflow path more rational, helping to slow down and concentrate the airflow, thereby creating a larger negative pressure area in the collection component, making it easier for sawdust to enter and be effectively collected. The collection component provides a professional space for sawdust collection and storage.

[0008] Optionally, multiple insert rods are vertically fixed on the sleeve, and multiple insert tubes are vertically fixed on the top surface of the lower ring plate, with the multiple insert tubes and multiple insert rods being vertically slidably inserted into each other.

[0009] By adopting the above technical solution, and by setting multiple vertical inserts and tubes, the inserts and tubes are connected by a vertical sliding insertion method, which serves the function of connecting the sleeve and the lower ring plate.

[0010] Optionally, multiple inserts are vertically fitted with compression springs, and the upper and lower ends of the compression springs are respectively fixed to the adjacent end faces of the sleeve and the lower ring plate.

[0011] By adopting the above technical solution, a compression spring is vertically sleeved on the outside of the insertion rod, and the upper and lower ends of the compression spring are respectively fixed to the adjacent end faces of the sleeve and the lower ring plate. When the insertion rod and the insertion tube are inserted, the compression spring will deform, thereby generating downward pressure to make it more tightly embedded, thus enhancing the stability and sealing of the overall structure.

[0012] Optionally, rollers are horizontally rotatably connected to both sides of the lower ring plate, and a rubber ring is horizontally fixed on the bottom surface of the lower ring plate.

[0013] By adopting the above technical solution, rollers are horizontally rotatably connected to both sides of the lower ring plate. These rollers can rotate flexibly during movement, reducing frictional resistance in the direction of motion. Furthermore, a rubber ring is horizontally fixed to the bottom surface of the lower ring plate. This rubber ring possesses good elasticity and wear resistance, providing continuous support and shock absorption during operation.

[0014] Optionally, the collection component includes a collection box, with a through-hole at the top of the collection box, and the through-hole at the top of the collection box is connected and fixed to the bottom of the bend.

[0015] By adopting the above technical solution, and by setting up a collection box and a connecting port, with the connecting port of the collection box connected and fixed to the bottom end of the bend, gas or other fluids can be smoothly introduced into the collection box from the bend. Since a suction pump is connected and fixed to the exhaust pipe of the collection box, the gas or fluid in the collection box can be effectively discharged through the suction action of the pump. Specifically, the suction pump generates negative pressure, causing the gas or fluid in the collection box to be drawn into the suction pump and discharged through the connecting port and the bend. This allows for efficient collection and discharge of gas or fluid, preventing it from escaping into the external environment.

[0016] Optionally, an exhaust pipe is vertically connected and fixed to the bottom surface of the collection box, and a suction pump is connected and fixed to the exhaust pipe of the collection box.

[0017] By adopting the above technical solution and setting up a suction pump, the gas in the collection box is effectively discharged to the outside due to the negative pressure generated by the suction pump. This effectively discharges gas or fluid, keeps the working environment clean, and prevents pollution.

[0018] Optionally, a filter screen is horizontally fixed inside the collection box, and a vertical cylinder is vertically connected and fixed in the middle of the top surface of the filter screen.

[0019] By adopting the above technical solution, a filter screen is horizontally fixed inside the collection box, and a vertical cylinder is vertically connected to the top of the filter screen. Cloth pads are respectively fitted on the outer walls of the filter screen and the vertical cylinder. This is because the filter screen can efficiently filter the debris collected in the collection box, while the vertical cylinder provides a guiding path for the debris, making the collection more concentrated.

[0020] Optionally, cloth pads are fitted on the top surface of the filter screen and the outer wall of the vertical cylinder.

[0021] By adopting the above technical solution, the presence of the cloth pad increases the contact area and friction between the filter screen and the vertical cylinder, which allows the debris entering the vertical cylinder to be guided more stably and reduces the scattering of debris.

[0022] In summary, this application includes at least one of the following beneficial technical effects: A composite elastic system consisting of a downward spring and a tightening spring ensures that the drive sleeve and lower ring plate assembly remain firmly in contact with the wooden door surface throughout the drilling process. The rubber ring deforms under pressure, perfectly filling the microscopic gaps between the dust collection hood and various irregular wooden door surfaces, forming a dynamic, leak-free sealing ring that fundamentally cuts off the path for sawdust to escape from the bottom of the dust collection hood. It boasts excellent dimensional and working condition adaptability and is highly versatile, using a fabric corrugated tube as a connecting component. Its excellent extensibility allows the dust collection hood to freely extend and retract within a wide range of strokes. This structure enables the device to perfectly adapt to the drilling depth requirements of wooden doors of different thicknesses and to cope with height changes during the downward and upward movements of the drilling arm, achieving full coverage for processing various sizes of wooden doors.

[0023] The dust collection hood is integrated directly onto the outside of the drilling motor, maximizing the proximity of the suction port to the sawdust-generating point. Under the negative pressure generated by the suction pump, sawdust is instantly drawn into the sealed channel formed by the corrugated pipe, achieving near-source capture through immediate collection. Combined with dual filtration of a filter screen and cloth pad, sawdust is efficiently retained in the collection box, fundamentally solving the problem of debris accumulation on the workshop floor. The entire sawdust collection system and drilling equipment are integrated into a coordinated operating unit. The pressing, sealing, and follow-up processes of the dust collection hood are entirely automated by the mechanical structure, requiring no manual intervention. This simplifies the operation process, ensures the stability and consistency of dust collection, and significantly reduces the labor intensity of workers and the frequency of workshop cleaning.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a sawdust collection device for a wooden door drilling and forming production line. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A sawdust collection device for a wooden door drilling and forming production line includes a drilling device 1, a dust collection component 2, a suction pipe 3, and a collection component 4. The upper part of the drilling device 1 is adjustablely equipped with a drilling arm 11, and a drilling motor is vertically fixed on the bottom surface of the drilling arm 11. The dust collection component 2 includes a sleeve 21, a corrugated pipe 23, and a lower ring plate 27. The sleeve 21 is vertically slidably mounted on the drilling motor of the drilling arm 11, and a downward pressure spring 22 is vertically fixed on the top surface of the sleeve 21. The top of 22 is fixed to the bottom surface of the drilling arm 11. The corrugated pipe 23 is vertically connected and fixed to the bottom surface of the sleeve 21. A lower ring plate 27 is horizontally fixed to the bottom surface of the corrugated pipe 23. A rubber ring 28 is vertically fixed to the bottom surface of the lower ring plate 27. A suction shell 29 is connected and fixed to the outer wall of the sleeve 21. A suction pipe 3 is connected and fixed to the end of the suction shell 29. A bend pipe 31 is connected and fixed to the other end of the suction pipe 3. A collection piece 4 is vertically connected and fixed to the bottom end of the bend pipe 31.

[0028] By adopting the above technical solution, and by setting up the drilling arm 11 and the drilling motor, the drilling arm 11 can be adjusted up and down according to actual processing needs, allowing the drilling motor to adapt to the processing requirements of wooden doors of different heights, thus improving the applicability and flexibility of the drilling equipment 1. Since the drilling motor is vertically fixed to the bottom surface of the drilling arm 11, the drilling arm 11 ensures the stability of the drilling motor during up and down adjustment, avoiding vibration or displacement caused during adjustment, thereby ensuring the accuracy and stability of the drilling. By setting up the dust collection component 2, the device composed of the sleeve 21 and the downward pressure spring 22 not only stably supports the dust collection component 2 during the drilling process, but also ensures that the vertical position of the dust collection component 2 changes synchronously when the drilling arm 11 moves up and down, ensuring the stability of the dust collection effect. The corrugated pipe 23 effectively improves the flexibility of the pipe, allowing the vacuum cleaner to flexibly adapt to changes in angle and height during the drilling process, avoiding blockages or inconvenience caused by fixed pipes. The combined use of the lower ring plate 27 and the rubber ring 28 enhances the adsorption force on sawdust at the drilled hole. The softness of the rubber ring 28 allows it to better fill the gaps in the drilled hole, further improving the dust collection effect. By setting up the suction shell 29 and the suction pipe 3, a closed suction duct system is formed, which not only ensures the stability and efficiency of the dust collection effect but also reduces air resistance, making the suction force between the suction component 2 and the collection component 4 more uniform and improving the efficiency of sawdust collection. The introduction of the curved pipe 31 makes the airflow path more reasonable, helping to slow down and concentrate the airflow, thereby creating a larger negative pressure area in the collection component 4, making it easier for sawdust to enter and be effectively collected. The collection component 4 provides a professional space for sawdust collection and storage.

[0029] Reference Figure 4 Multiple insertion rods 25 are vertically fixed on the sleeve 21, and multiple insertion tubes 24 are vertically fixed on the top surface of the lower ring plate 27. The insertion tubes 24 are vertically slidably inserted into the multiple insertion rods 25. By setting multiple vertical insertion rods 25 and insertion tubes 24, the insertion rods 25 and insertion tubes 24 are connected by vertical sliding insertion, thus connecting the sleeve 21 and the lower ring plate 27. A compression spring 26 is vertically fitted around the outside of the multiple insertion rods 25, and the upper and lower ends of the compression spring 26 are respectively fixed to the adjacent end faces of the sleeve 21 and the lower ring plate 27. When the insertion rods 25 and insertion tubes 24 are inserted, the compression spring 26 deforms, generating downward pressure to make them embed more tightly, thereby enhancing the stability and sealing of the overall structure.

[0030] Reference Figure 3Both sides of the lower ring plate 27 are horizontally rotatably connected to rollers 271, and a rubber ring 28 is horizontally fixed on the bottom surface of the lower ring plate 27. By setting the rollers 271 horizontally rotatably connected to both sides of the lower ring plate 27, the rollers 271 can rotate flexibly during movement, reducing frictional resistance in the direction of movement. In addition, the rubber ring 28 horizontally fixed on the bottom surface of the lower ring plate 27 has good elasticity and wear resistance, and can provide continuous support and shock absorption during operation.

[0031] Reference Figure 4 and Figure 5 The collecting component 4 includes a collecting box 41, with a connecting port 42 extending through its top end. This connecting port 42 is fixedly connected to the bottom end of a bent pipe 31. By configuring the collecting box 41 and the connecting port 42, and ensuring the connection between the connecting port 42 and the bottom end of the bent pipe 31, gas or other fluids can be smoothly introduced into the collecting box 41 from the bent pipe 31. Since a suction pump 43 is fixedly connected to the exhaust pipe of the collecting box 41, the suction action of the suction pump 43 effectively removes the gas or fluid from the collecting box 41. Specifically, the suction pump 43 generates negative pressure, causing the gas or fluid in the collecting box 41 to be drawn into the suction pump 43 through the connecting port 42 and the bent pipe 31 and then discharged. This efficiently collects and discharges the gas or fluid, preventing it from escaping into the external environment. An exhaust pipe is vertically fixed to the bottom surface of the collecting box 41, and the suction pump 43 is fixedly connected to the exhaust pipe. By installing a suction pump 43, the negative pressure generated by the pump effectively discharges the gas inside the collection box 41 to the outside, thus effectively discharging gas or fluid, maintaining a clean working environment, and preventing pollution. A filter screen 44 is horizontally fixed inside the collection box 41, and a vertical cylinder 45 is vertically connected and fixed to the center of the top surface of the filter screen 44. The filter screen 44 is horizontally fixed inside the collection box 41, and the vertical cylinder 45 is vertically connected to the center of the top surface of the filter screen 44. Both the filter screen 44 and the outer wall of the vertical cylinder 45 are fitted with cloth pads 46. This is because the filter screen 44 can efficiently filter the debris collected in the collection box 41, while the vertical cylinder 45 provides a guiding path for the debris, making the collection more concentrated. The cloth pads 46 increase the contact area and friction between the filter screen 44 and the vertical cylinder 45, allowing debris entering the vertical cylinder 45 to be guided more stably and reducing debris scattering.

[0032] The implementation principle of a sawdust collection device for a wooden door drilling and forming production line according to an embodiment of this application is as follows: First, the sleeve 21 of the vacuum cleaner 2 is vertically sleeved on the outside of the drilling motor of the drilling arm 11. Then, the top of the compression spring 22 on the top surface of the sleeve 21 is fixed to the top surface of the drilling arm 11. Then, one end of the suction pipe 3 is connected to the end of the suction shell 29 on the vacuum cleaner 2. Then, the bent pipe 31 is connected to the suction pipe 3 and assembled. At the same time, the collection box 41 of the collection component 4 is connected to the other end of the bent pipe 31 and assembled. The vacuum cleaner 2, the suction pipe 3 and the collection component 4 are connected and assembled to form a wood chip collection and dust removal channel. Then, when drilling holes in the wooden door, the drilling arm 11 is started and moved vertically downward, driving the drilling motor to drive the drill rod to drill into the wooden door. The drilling arm 11 drives the dust collection component 2 to move downward as well. At the same time, the deformation force of the lower pressure spring 22 pushes the sleeve 21 to slide vertically downward on the drilling motor, so that the rubber ring 28 on the bottom surface of the lower ring plate 27 deforms and presses against the surface of the wooden door, so that there is no leakage gap between the wooden door and the rubber ring 28. At the same time, when the drilling motor drives the drill rod to move upward, the pressure spring 26 pushes the lower ring plate 27 to always press against the wooden door. The corrugated pipe 23 made of cloth can be extended and expanded. Finally, when collecting sawdust, start the suction pump 43 on the exhaust pipe on the bottom surface of the collection box 41 to create negative pressure in the corrugated pipe 23, which will drive air into the corrugated pipe 23 and carry the sawdust generated by drilling from the suction shell 29 into the suction pipe 3. The sawdust is then guided into the collection box 41 from the bend pipe 31. The sawdust is filtered and removed by the filter screen 44 and the cloth pad 46 and left in the collection box 41. Finally, the air is discharged from the exhaust pipe on the bottom surface of the collection box 41.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
