Description

Technical Field

[0001] This utility model belongs to the field of furniture manufacturing technology, specifically relating to a dust reduction device for bedside table production. Background Technology

[0002] In the production and processing of bedside tables, saw cutting is an indispensable and crucial process, mainly used for cutting cabinet panels to a fixed length and width, as well as creating grooves. However, this process has the following two problems, affecting production efficiency, product quality, and the working environment.

[0003] First, there is the issue of dust pollution. When the saw blade rotates at high speed to cut wooden cabinet panels, it generates a large amount of sawdust and dust. This dust not only permeates the work area and harms the health of operators when inhaled, but also adheres to the surfaces of transmission parts and electrical components of the production equipment, accelerating equipment wear and increasing the failure rate. Furthermore, dust scattered on workbenches and floors requires additional manpower for cleaning, increasing production support costs.

[0004] Secondly, there is the issue of saw blade overheating. During high-speed cutting of cabinet panels, the saw blade experiences intense friction and collisions with the wood, generating a significant amount of heat. If this heat cannot be dissipated in time, the saw blade temperature will rise rapidly. At high temperatures, the mechanical properties of the saw blade will change, with decreased hardness and increased brittleness. This not only reduces cutting accuracy, leading to rough cut edges and dimensional deviations, affecting the assembly quality of the bedside table, but also shortens the saw blade's lifespan, increasing production costs due to frequent blade replacements. Currently, most measures for cooling saw blades employ a single air-cooling method, such as placing an air vent on one side of the saw blade to blow air directly onto it. However, this method has significant drawbacks: due to the high-speed rotation of the saw blade, a single-direction airflow cannot fully cover the saw blade surface, resulting in uneven cooling; if the airflow is too large and blown directly onto the hot saw blade, causing large local temperature differences, the saw blade is prone to deformation due to uneven thermal stress, further affecting cutting performance.

[0005] Therefore, there is an urgent need for a device that can effectively collect cutting dust while efficiently and uniformly cooling the saw blade, in order to solve the aforementioned technical problems faced in the saw blade cutting process during bedside table production. Utility Model Content

[0006] To address the above problems, the purpose of this utility model is to provide a dust collection device for bedside table production, which solves the problems of poor dust collection, uneven cooling of saw blades, and easy deformation in the existing technology during saw blade cutting in bedside table production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a dust removal and cooling device for bedside table production, comprising a dust removal and cooling mechanism, wherein the dust removal and cooling mechanism consists of a dust collection trough, a filter box, a fan, and a dual cooling component. The dust collection trough is composed of two angle steels arranged opposite to each other on both sides of a saw blade. The saw blade is fixed to one end of a drive shaft, which is rotatably mounted on a bearing seat and connected to a motor via a belt drive mechanism. The upper side of the saw blade passes through a slot opened at the top of the sawing machine frame. The dust collection trough, the motor, and the bearing seat are fixed on the sawing machine frame. One end of the dust collection trough is connected to the air inlet of the filter box through an air inlet pipe. The air outlet of the filter box is connected to the air inlet of the fan. The air outlet of the fan is connected to one end of a Venturi tube in the dual cooling component. The other end of the Venturi tube faces the saw blade. An exhaust pipe is installed at the throat of the Venturi tube, and the top end of the exhaust pipe faces the saw blade.

[0008] The beneficial effects of this utility model are as follows: while collecting the debris generated by the cutting cabinet plate under negative pressure, the dust removal and cooling mechanism cools the saw blade in three parts in three stages through the setting of the dust suction groove, venturi tube and air extraction pipe. By increasing the air cooling area and gradient cooling, the cooling efficiency is effectively improved, and saw blade deformation caused by excessive local cooling can be avoided.

[0009] To effectively collect sawdust generated during the cutting process by using a dust collection trough;

[0010] As a further improvement to the above technical solution: the air intake pipe includes an air collection groove and a bend. The end of the air collection groove that connects to the angle steel has a groove that is flush with the inner wall of the angle steel. The two ends of the bend are respectively connected to the air collection groove and the filter box. The end of the angle steel facing away from the air collection groove is welded with a square plate that is flush with the inner wall of the angle steel. The two angle steels are set on the outside of the groove for installing the saw blade on the saw frame.

[0011] The beneficial effects of this improvement are as follows: the two angle steels together form a guide channel, which, under negative pressure, allows the wood chips generated during the saw blade cutting process to be effectively sucked into the air intake pipe, while the saw blade is cooled for the first time by the flowing air.

[0012] In order to effectively collect sawdust through the use of a filter box;

[0013] As a further improvement to the above technical solution: the filter box includes an outer shell, the top side of the outer shell is connected to one end of a bend, the bottom end of the outer shell is threaded with a cover, a filter cartridge is sandwiched between the cover and the outer shell, and a through hole is opened on the top of the outer shell inside the filter cartridge to connect with the air inlet of the fan.

[0014] The beneficial effects of this improvement are: when the fan is working, the wood chips are sucked into the interior of the outer casing and isolated by the filter cartridge, thereby effectively collecting the wood chips.

[0015] To ensure the filtration effect of the filter cartridge;

[0016] As a further improvement to the above technical solution: sealing gaskets are bonded to both ends of the filter cartridge.

[0017] The beneficial effect of this improvement is that the sealing gasket achieves an effective sealing effect after being elastically deformed by the compression between the cover, the outer shell and the filter cartridge.

[0018] In order to effectively cool the saw blade again by using a venturi tube;

[0019] As a further improvement to the above technical solution: the axis of the venturi tube is tangent to the circle containing the outer edge of the saw blade.

[0020] The beneficial effect of this improvement is that the airflow from the venturi tube can effectively cool the saw blade again.

[0021] In order to effectively cool the saw blade again by using an exhaust pipe;

[0022] As a further improvement to the above technical solution: the axis of the air extraction pipe is tangent to the circle containing the outer edge of the saw blade.

[0023] The beneficial effect of this improvement is that the airflow drawn into the extraction pipe under negative pressure can effectively cool the saw blade again.

[0024] To ensure the stability of the saw blade rotation;

[0025] As a further improvement to the above technical solution: the driving pulley and the driven pulley in the belt drive mechanism are respectively installed at one end of the output shaft and the drive shaft of the motor.

[0026] The beneficial effect of this improvement is that the motor can drive the saw blade to rotate stably through the belt drive mechanism.

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0034] Example 1:

[0035] like Figure 1As shown in Figure 4: A dust removal device for bedside table production includes a dust removal and cooling mechanism 1. The dust removal and cooling mechanism 1 consists of a dust collection trough 2, a filter box 4, a fan 5, and a dual cooling component 6. The dust collection trough 2 is composed of two angle steels 21 arranged opposite to each other on both sides of a saw blade 9. The saw blade 9 is fixed to one end of a drive shaft 10. The drive shaft 10 is rotatably mounted on a bearing seat 11 and is connected to a motor 13 via a belt drive mechanism 12. The upper side of the saw blade 9 passes through a slot opened at the top of a sawing machine frame 8. The dust collection trough 2, the motor 13, and the bearing seat 11 are fixed on the sawing machine frame 8. One end of the dust collection trough 2 is connected to the air inlet of the filter box 4 via an air inlet pipe 3. The air outlet of the filter box 4 is connected to the air inlet of the fan 5. The air outlet of the fan 5 is connected to one end of the Venturi tube 61 in the dual cooling assembly 6. The other end of the Venturi tube 61 faces the saw blade 9. An extraction pipe 62 is installed at the throat of the Venturi tube 61, and the top of the extraction pipe 62 faces the saw blade 9. While collecting debris generated by the cutting cabinet plate under negative pressure, the dust removal and cooling mechanism 1 cools the saw blade 9 in three stages at three locations through the arrangement of the dust collection groove 2, the Venturi tube 61, and the extraction pipe 62. By increasing the air-cooled area and using gradient cooling, the cooling efficiency is effectively improved, and saw blade deformation caused by excessively rapid local cooling can be avoided. The air inlet pipe 3 includes an air collection groove 31 and a bend 32. The end of the air collection groove 31 that connects to the angle steel 21 has a bend flush with the inner wall of the angle steel 21. The slot is formed by connecting the two ends of the bend 32 to the air collection slot 31 and the filter box 4, respectively. A square plate with its inner wall flush with the side of the angle steel 21 facing away from the air collection slot 31 is welded to the end of the angle steel 21. Two angle steels 21 are positioned outside the slot for mounting the saw blade 9 on the saw frame 8. The two angle steels 21 together form a guide channel, effectively drawing the wood chips generated during the saw blade 9's cutting process into the air intake pipe 3 under negative pressure. Simultaneously, the flowing air performs the first cooling treatment on the saw blade 9. The filter box 4 includes an outer shell 41, the top of which is connected to one end of the bend 32. A cover 42 is threaded to the bottom of the outer shell 41, and a filter cylinder 43 is sandwiched between the cover 42 and the outer shell 41. The top of the outer shell 41 inside the filter cartridge 43 has a through hole that connects to the air inlet of the blower 5. When the blower 5 is working, sawdust is sucked into the interior of the outer shell 41 and isolated by the filter cartridge 43, thus effectively collecting the sawdust. Both ends of the filter cartridge 43 are glued with sealing gaskets. The sealing gaskets undergo elastic deformation under the pressure between the cover 42, the outer shell 41, and the filter cartridge 43, thus providing an effective seal. The axis of the venturi tube 61 is tangent to the circle containing the outer edge of the saw blade 9. The airflow blown out by the venturi tube 61 can effectively cool the saw blade 9 again. The axis of the exhaust pipe 62 is tangent to the circle containing the outer edge of the saw blade 9. Under negative pressure, the airflow sucked into the exhaust pipe 62 can effectively cool the saw blade 9 again.The driving pulley and driven pulley in the belt drive mechanism 12 are respectively installed at one end of the output shaft of the motor 13 and one end of the drive shaft 10. The motor 13 can drive the saw blade 9 to rotate stably through the belt drive mechanism 12.

[0036] The working principle of this technical solution is as follows: The motor 13 is started, and the motor 13 drives the drive shaft 10 to rotate through the belt transmission mechanism 12, which in turn drives the saw blade 9 to rotate at high speed under the support of the bearing seat 11. At this time, the upper side of the saw blade 9 passes through the slot at the top of the saw frame 8 and is in the state of waiting to be cut. Then the fan 5 is started, and the operator pushes the cabinet panel to be cut to the saw blade 9 for cutting. During the cutting process, a large amount of wood chips and dust are generated and flow along the dust collection groove 2 composed of two angle steels 21 under the action of negative pressure. Since the end of the angle steel 21 facing away from the air collection groove 31 is welded with a square plate that is flush with the inner wall, it can effectively prevent dust from escaping from the end. After being guided by the angle steel 21, the dust enters the air collection groove 31 of the air inlet pipe 3. The slot that is flush with the inner wall of the angle steel 21 ensures that the dust can enter smoothly. Then the dust enters the outer shell 41 of the filter box 4 through the bent pipe 32.

[0037] Inside the filter box 4, dust is isolated and collected by the filter cartridge 43. The sealing gaskets at both ends of the filter cartridge 43 undergo elastic deformation under the pressure of the cover 42 and the outer shell 41, achieving a good seal and preventing unfiltered dusty airflow from entering the fan 5. The filtered clean airflow enters the Venturi tube 61 of the secondary cooling component 6 under the action of the fan 5. The airflow accelerates within the Venturi tube 61 and is ejected from one end toward the saw blade 9. Since the axis of the Venturi tube 61 is tangent to the outer edge of the saw blade 9, the ejected airflow can accurately act on the saw teeth of the saw blade 9, performing a second cooling on the saw blade 9. At the same time, under the negative pressure generated at the throat of the Venturi tube 61, the exhaust pipe 62 will draw in outside air. The axis of the exhaust pipe 62 is also tangent to the outer edge of the saw blade 9. When the airflow flows over the surface of the saw blade 9, it performs a third cooling on the saw teeth.
