Description

Technical Field

[0001] This invention belongs to the technical field of dust removal equipment, specifically relating to a dust removal device for a decorative panel carving machine. Background Technology

[0002] A decorative panel engraving machine is a device used for engraving decorative panels. It places and fixes the panel onto a processing platform according to design requirements, then moves the processing head according to the engraving pattern, using cutting tools to engrave various patterns, text, or shapes on the surface of the decorative panel to meet different decorative needs. An engraving machine typically includes a processing platform, a gantry that moves on the processing platform, and a processing head that can move along the length of the gantry.

[0003] Therefore, some engraving machines are not equipped with dust removal devices after being purchased and brought back to the factory. After the decorative panel engraving is completed, manual cleaning of the debris generated during the engraving process is usually required. On the one hand, this operation is tedious and consumes a lot of manpower; on the other hand, the fine debris can easily spread inside the processing workshop, affecting the working environment. To improve the on-site processing environment, a dust suction hood is added to the processing head to remove debris in a timely manner. However, currently, the dust suction hood is usually placed above the processing head, and due to the obstruction of the dust suction hood and debris, it is not convenient for on-site operators to observe the engraving process. Summary of the Invention

[0004] This invention provides a dust removal device for a decorative panel engraving machine, which aims to solve the problem that adding a dust hood to a decorative panel engraving machine in the prior art makes it inconvenient for on-site operators to observe and monitor the engraving process.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a dust removal device for a decorative panel engraving machine, comprising: A dust collection hood is installed at the bottom of the gantry of the engraving machine and on one side of the processing head. The length of the dust collection hood is arranged along the length of the gantry, and the dust collection port of the dust collection hood is located on the side closer to the processing head. Multiple longitudinal partitions are fixedly installed at intervals inside the dust hood along its length to divide the dust hood into multiple dust chambers. An air suction chamber is provided on the same side of the multiple dust chambers, and the air suction chamber is connected to the multiple dust chambers. A control component is disposed at the connection between the dust collection chamber and the air suction chamber, and is used to realize the connection between the dust collection chamber and the air suction chamber when the processing head moves to the dust suction port of the dust collection chamber.

[0006] In one possible implementation, a horizontal partition is also fixedly installed inside the dust collection chamber, which is used to divide the dust collection chamber into an upper exhaust channel and a lower exhaust channel, wherein the width of the dust inlet of the lower exhaust channel is smaller than the width of the dust inlet of the upper exhaust channel.

[0007] In one possible implementation, the control component includes: A baffle is installed on the side of the dust collection chamber near the air intake chamber. The baffle can cover the connection between the dust collection chamber and the air intake chamber to seal off the flow of the dust collection chamber. An adjustment component is disposed between the baffle and the suction chamber for adjusting the movement of the baffle in a direction closer to or further away from the suction chamber.

[0008] In one possible implementation, the regulating component includes: A sliding seat is fixedly installed on the baffle plate. The sliding seat is slidably disposed inside the air suction chamber, and the sliding direction of the sliding seat is inclined upward in the direction away from the dust suction chamber. The lifting component is slidably disposed on the air intake chamber in a vertical direction, and the top of the sliding seat is slidably disposed on the lifting component in a direction that is horizontal and perpendicular to the baffle. A push-pull assembly is disposed between the lifting member and the processing head, and is used to drive the lifting member to move up and down on the air intake chamber.

[0009] In one possible implementation, the push-pull component includes: The tray is fixedly installed on the lifting member; A lifting plate is fixedly installed at the bottom of the processing head. Both ends of the lifting plate are bent downwards, and the lifting plate can be moved to the bottom of the support plate to push the support plate upwards. An elastic element is installed between the lifting member and the air intake chamber to push the lifting member downward.

[0010] In one possible implementation, a buffer member is fixedly installed on the top of the air intake chamber, a buffer chamber is provided inside the buffer member, a piston part is provided in the middle of the lifting member and is slidably disposed inside the buffer chamber, and a buffer structure is provided inside the buffer chamber for buffering the downward movement of the piston part.

[0011] In one possible implementation, the bottom of the buffer chamber is provided with a first vent and a second vent, the second vent having a conical structure, and a sealing ball for sealing the second vent is movably installed inside the second vent.

[0012] In one possible implementation, the baffle is provided with a protruding annular rib, which slides in conjunction with the inner wall of the upper exhaust channel.

[0013] In one possible implementation, a guide plate is fixedly installed on the inner wall of the air intake chamber, and the baffle is provided with a slot that slides with the guide plate.

[0014] In one possible implementation, the dust hood is slidably mounted on the gantry in a vertical direction, and both ends of the dust hood are rotatably mounted with support wheels that are rolled on the machine tool.

[0015] The solution shown in this application, compared with the prior art, features a long, narrow dust collection hood, typically installed at the bottom of the gantry of the engraving machine on the processing side, with the dust collection port facing the processing head. Multiple longitudinal partitions are fixedly installed inside the dust collection hood, dividing it into multiple dust collection chambers. An air suction chamber is also located inside the dust collection hood, situated on the same side of the multiple dust collection chambers and interconnected with them. Each dust collection chamber has its end connected to a dust collection port and an air suction chamber, respectively. A control component manages the connection between the dust collection chambers and the air suction chamber. When the processing head moves to the corresponding dust collection chamber, the control component opens the connection between the chamber and the air suction chamber, allowing the dust collection chamber to switch to suction mode and effectively draw debris generated during engraving into the air suction chamber. Furthermore, the dust suction port of the dust hood is located on one side of the processing head, which can remove the generated debris from one side without affecting the engraving process, making it easier for the operator to observe the status of the engraving process and the engraving status of the tool.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] Please refer to the following: Figures 1 to 6 The dust removal device for a decorative panel engraving machine provided by the present invention will now be described. The dust removal device for the decorative panel engraving machine includes a dust collection hood 2, longitudinal partitions 3, and a control component 4. The dust collection hood 2 is installed at the bottom of the gantry 11 of the engraving machine 1 and is located on one side of the processing head 12. The length direction of the dust collection hood 2 is along the length direction of the gantry 11, and the dust collection port of the dust collection hood 2 is located on the side closer to the processing head 12. Multiple longitudinal partitions 3 are fixedly installed at intervals inside the dust collection hood 2 along its length direction, dividing the dust collection hood 2 into multiple dust collection chambers 22. A suction chamber 21 is provided on the same side of each of the multiple dust collection chambers 22, and the suction chamber 21 is connected to the multiple dust collection chambers 22. The control component 4 is located at the connection between the dust collection chamber 22 and the suction chamber 21, and is used to connect the corresponding dust collection chamber 22 and the suction chamber 21 when the processing head 12 moves to the dust collection port of the dust collection chamber 22.

[0020] The dust removal device for the decorative panel engraving machine provided in this embodiment, compared with the prior art, features a long, narrow dust collection hood 2. The dust collection hood 2 is typically installed at the bottom of the gantry 11 of the engraving machine 1, located on the processing side, with the dust collection port on the dust collection hood 2 facing the processing head 12. Multiple longitudinal partitions 3 are fixedly installed inside the dust collection hood 2, dividing the interior of the dust collection hood 2 into multiple dust collection chambers 22. Furthermore, an air suction chamber 21 is also provided inside the dust collection hood 2, located on the same side of the multiple dust collection chambers 22 and interconnected with them. The two ends of each dust collection chamber 22 are connected to the dust collection port and the air suction chamber 21, respectively. The communication state between the dust collection chambers 22 and the air suction chamber 21 is controlled by a control component 4. When the processing head 12 moves to the side of the corresponding dust collection chamber 22, the control component 4 can be used to open the corresponding dust collection chamber 22 and maintain communication with the air suction chamber 21, allowing the corresponding dust collection chamber 22 to switch to dust collection mode and effectively suck the debris generated during the engraving process into the air suction chamber 21. Furthermore, the dust collection port of the dust collection hood 2 is located on one side of the processing head 12, allowing the generated debris to be drawn away from one side without affecting the engraving process, making it easier for the operator to observe the status of the engraving process and the cutting tool's engraving status.

[0021] Specifically, in this embodiment, a telescopic tube communicating with the middle of the air intake chamber 21 is also installed on the machine tool. The telescopic tube is connected to a vacuum cleaner. After the debris during the carving process is sucked into the air intake chamber 21, it can be transported to the vacuum cleaner through the telescopic tube. The vacuum cleaner includes a dust collection bag for collecting debris.

[0022] Specifically, in this embodiment, the negative pressure generated inside the suction chamber 21 is produced by the vacuum cleaner's suction.

[0023] Preferably, in this embodiment, the dust hood 2 is divided into multiple dust chambers 22 by the partition plate 3, so that when the dust chamber 22 close to the processing head 12 is working, the other dust chambers 22 are closed, which can effectively utilize the negative pressure inside the suction chamber 21 to ensure the suction effect inside the dust chamber 22 in the open state.

[0024] In some embodiments, the above-mentioned dust collection chamber 22 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3The dust collection chamber 22 is also fixedly equipped with a horizontal partition 5, which divides the dust collection chamber 22 into an upper exhaust channel and a lower exhaust channel. The width of the dust inlet of the lower exhaust channel is smaller than that of the dust inlet of the upper exhaust channel. Through the partition 5, the dust collection chamber 22 can be divided into an upper exhaust channel and a lower exhaust channel. Furthermore, the exhaust area of ​​the dust inlet of the upper exhaust channel is larger than that of the dust inlet of the lower exhaust channel. In practical applications, the exhaust channels can suck up larger particles and debris that fall onto the decorative panel, while the upper exhaust channel is used to suck up debris that diffuses into the air during the carving process.

[0025] Specifically, in this embodiment, the dust outlets of the upper and lower exhaust channels have the same air outlet area, which increases the suction force of the lower exhaust channel. Correspondingly, large particles of debris can be effectively drawn into the suction chamber 21, ensuring effective dust removal.

[0026] In some embodiments, the control component 4 described above may employ, for example... Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The control component 4 includes a baffle 41 and an adjustment component 42. The baffle 41 is installed on the side of the suction chamber 22 near the air intake chamber 21, and can cover the connection between the suction chamber 22 and the air intake chamber 21 to seal the flow of air in the suction chamber 22. The adjustment component 42 is disposed between the baffle 41 and the air intake chamber 21, and is used to adjust the movement of the baffle 41 towards or away from the suction chamber 22. The baffle 41 is installed at the dust outlet of the suction chamber 22, and is slidably disposed inside the air intake chamber 21, moving towards or away from the suction chamber 22. By adjusting the position of the baffle 41 using the adjustment component 42, the baffle 41 can be made to fit against the dust outlet of the suction chamber 22, sealing the dust outlet and achieving a closed effect on the suction chamber 22. When the processing head 12 moves to the corresponding dust collection chamber 22, the baffle 41 can be moved away from the dust collection chamber 22 by adjusting the component 42, so that the dust outlet of the dust collection chamber 22 is connected to the air suction chamber 21, and the working state is achieved.

[0027] In some embodiments, the adjustment component 42 may employ, for example... Figure 3 , Figure 4 The structure shown. See also... Figure 3 , Figure 4The adjusting assembly 42 includes a sliding seat 421, a lifting member 422, and a push-pull assembly 43. The sliding seat 421 is fixedly mounted on the baffle 41 and slidably disposed inside the suction chamber 21, with its sliding direction inclined upwards away from the suction chamber 22. The lifting member 422 is slidably disposed vertically on the suction chamber 21, with the top of the sliding seat 421 slidably disposed horizontally and perpendicular to the baffle 41 on the lifting member 422. The push-pull assembly 43 is disposed between the lifting member 422 and the processing head 12, used to drive the lifting member 422 to move up and down on the suction chamber 21. The sliding seat 421 is fixedly mounted on the side of the baffle 41 away from the suction chamber 22, and slides against the inner wall of the bottom of the suction chamber 21. The lifting member 422 includes two mounting plates with elongated holes on each plate. A guide rod is fixedly mounted on the sliding seat 421, and the guide rod slidably disposed inside the corresponding elongated holes on the two mounting plates. The sliding seat 421 is tilted and slidably disposed inside the suction chamber 21, so that when the lifting member 422 moves up and down, it can simultaneously drive the sliding seat 421 to move closer to or away from the suction chamber 22.

[0028] Specifically, in this embodiment, when the dust hood 2 is installed on the gantry frame 11, the inner wall of the bottom of the suction chamber 21 is inclined. This allows it to move synchronously away from the dust chamber 22 when the push-pull assembly 43 pulls the sliding seat 421 upward.

[0029] Specifically, in this embodiment, a push-pull assembly 43 is provided between the processing head 12 and the lifting member 422, so that the processing head 12 provides a force on the lifting member 422. Thus, the working state of the dust collection chamber 22 can be indirectly adjusted according to the position of the processing head 12.

[0030] In some embodiments, the push-pull assembly 43 may employ, for example... Figure 3 The structure shown. See also Figure 3The push-pull assembly 43 includes a support plate 431, a lifting plate 432, and an elastic element 433. The support plate 431 is fixedly mounted on the lifting member 422; the lifting plate 432 is fixedly mounted on the bottom of the processing head 12, with both ends bent downwards, and the lifting plate 432 is movable below the support plate 431 to push the support plate 431 upwards; the elastic element 433 is installed between the lifting member 422 and the suction chamber 21 to push the lifting member 422 downwards. Two guide rods are fixedly mounted on the top of the lifting member 422, slidingly disposed on the top of the suction chamber 21 and passing through the top of the suction chamber 21. The support plate 431 is fixedly mounted on the top of the two guide rods, spaced apart from the top of the suction chamber 21. The length direction of both the support plate 431 and the lifting plate is along the length direction of the gantry 11 of the engraving machine 1. The lifting plate 432 is mounted on the processing head 12 of the engraving machine 1. When the processing head 12 moves on the gantry 11, the end of the lifting plate 432 first moves to below the support plate 431, and drives the support plate 431 to move upward through the guide at the end, thereby driving the lifting member 422 to move upward. When the processing head 12 moves and causes the lifting plate 432 to disengage from the support plate 431, it can push the lifting member 422 downward under the action of the elastic member 433.

[0031] Specifically, in this embodiment, the processing head 12 of the engraving machine 1 is a part that can only move along the length of the gantry 11 on the gantry frame 11. A clamping head for clamping tools is also installed on the processing head 12, which can slide in the vertical direction.

[0032] Preferably, in this embodiment, the length of the lifting plate 432 excluding the inclined portions at both ends is greater than the length of the support plate 431, and the support plates 431 corresponding to two adjacent dust collection chambers 22 are connected end to end. This allows the lifting plate 432 to simultaneously lift the support plates 431 corresponding to three adjacent dust collection chambers 22, enabling the three adjacent dust collection chambers 22 to achieve the dust collection effect and increasing the dust collection area.

[0033] In some embodiments, the lifting member 422 may be adopted as follows: Figure 3 , Figure 5 The structure shown. See also... Figure 3 , Figure 5 A buffer member 6 is fixedly installed on the top of the suction chamber 21. A buffer chamber is provided inside the buffer member 6. A piston part 423 is slidably disposed inside the buffer chamber in the middle of the lifting member 422. A buffer structure is provided inside the buffer chamber to buffer the downward movement of the piston part 423. A guide rod is fixedly installed on the top of the lifting member 422. The guide rod is fixedly connected to the piston part 423 and slidably disposed at both ends of the buffer member 6.

[0034] Specifically, in this embodiment, the design of the buffer 6 allows the lifting member 422 to move slowly downwards under the action of the elastic member 433 after the lifting plate 432 disengages from the support plate 431. This achieves the slow closing of the dust collection chamber 22. In practical applications, when the processing head 12 moves to the corresponding dust collection chamber 22, some debris will still remain inside the dust collection chamber 22. By slowly closing the dust collection chamber 22, the suction time for debris can be extended, thereby reducing the residue of debris inside the dust collection chamber 22.

[0035] In some embodiments, the above-described buffer structure may employ, for example... Figure 5 The structure shown. See also Figure 5 The buffer structure includes a first vent 61 and a second vent 62 located at the bottom of the buffer chamber. The second vent 62 has a conical structure, and a sealing ball 63 for sealing the second vent 62 is movably installed inside the second vent 62. The middle part of the buffer member 6 is hollow, and the piston part 423 in the middle of the lifting member 422 is slidably disposed inside the buffer chamber, and the top of the buffer member 6 has a hollow structure. This makes the top of the piston part 423 an open cavity, which does not affect the vertical movement of the piston part 423 inside the buffer chamber. The bottom of the buffer member 6 is a sealed structure, and the first vent 61 and the second vent 62 are provided at the bottom of the buffer member 6, communicating with the buffer chamber. When the piston part 423 moves upward, the sealing ball 63 moves into the buffer chamber, thereby keeping the second vent 62 in communication with the buffer chamber. Gas can enter the buffer chamber through the first vent 61 and the second vent 62 together, thereby preventing negative pressure from forming below the buffer member 6 and ensuring that the piston part 423 can move upward smoothly.

[0036] When the piston 423 moves downward, the sealing ball 63 moves outward inside the second exhaust port 62, preventing the gas inside the buffer chamber from escaping through the second exhaust port 62. It can only escape through the first exhaust port 61. As the piston 423 moves downward, a positive pressure is generated inside the buffer chamber below the piston 423, reducing the downward speed of the piston 423. Then, after the lifting plate 432 on the processing head 12 disengages from the support plate 431 on the lifting member 422, the piston 423 moves slowly downward due to the inability of the gas inside the buffer chamber to escape quickly, pushed by the elastic member 433. This allows the baffle 41 to gradually close the connection between the dust collection chamber 22 and the suction chamber 21, maintaining the suction process in the dust collection chamber 22 for a period of time. This is used to suck up residual debris inside the dust collection chamber 22.

[0037] Preferably, in this embodiment, a small spring is also installed inside the buffer 6 to push the sealing ball 63 into the second exhaust hole 62 and cause the second exhaust hole 62 to be in a closed state.

[0038] In some embodiments, the baffle 41 may be as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 An annular rib 411 protrudes from the baffle 41 and slides against the inner wall of the upper exhaust duct. The annular rib 411 is located on the side of the baffle 41 closest to the dust collection chamber 22. A grille with multiple ventilation holes is installed at the air outlet of the upper exhaust duct. The number of annular ribs 411 on the baffle 41 corresponds one-to-one with the number of ventilation holes. When the baffle 41 moves closer to the dust collection chamber 22, the annular ribs 411 on the baffle 41 preferentially slide into the ventilation holes on the grille. This preferentially seals the upper exhaust duct, while a gap remains between the baffle 41 and the lower exhaust duct, thus strengthening the suction of the lower exhaust duct.

[0039] Preferably, in this embodiment, during actual application, the cutting head 12 on the engraving machine 1 generates flying debris at the cutting position. Therefore, the upper and lower exhaust ducts need to operate simultaneously to achieve effective dust reduction. When the cutting head 12 moves away from the processing position, some larger debris will fall onto the decorative panel. Then, the upper exhaust duct will close, reducing the connection area between the dust collection chamber 22 and the air suction chamber 21. Therefore, the suction power of the lower exhaust duct will increase, effectively drawing larger debris into the air suction chamber 21 through the lower exhaust duct.

[0040] Specifically, in this embodiment, the working process is as follows: when the processing head 12 of the engraving machine 1 moves to the corresponding dust collection chamber 22, the baffle 41 of the corresponding dust collection chamber 22 is opened, and the upper and lower exhaust channels operate simultaneously. The flying debris and the debris that falls on the decorative board are sucked into the suction chamber 21 together through the upper and lower exhaust channels. When the processing head 12 moves away from the corresponding dust collection chamber 22, the baffle 41 slowly moves towards the dust collection chamber 22, and the upper exhaust channel is closed first by the annular rib 411, thereby increasing the suction force on the lower exhaust channel and effectively sucking away the debris that falls on the decorative board.

[0041] In some embodiments, the mounting structure of the baffle 41 and the air intake chamber 21 can be as follows: Figure 4 The structure shown. See also Figure 4A guide plate 23 is fixedly installed on the inner wall of the air intake chamber 21, and a slot is provided on the baffle 41 to slide with the guide plate 23. The guide plate 23 is fixedly installed on the inner wall of the bottom of the air intake chamber 21, and the guide plate 23 is arranged parallel to the inner wall of the bottom of the air intake chamber 21 at intervals. A slot to slide with the guide plate 23 is provided on the side of the baffle 41, and a wing plate is also bent on the baffle 41 and slidably disposed between the guide plate 23 and the inner wall of the air intake chamber 21, so that the baffle 41 can be guided to slide in a direction parallel to the inner wall of the bottom of the air intake chamber 21.

[0042] Specifically, in this embodiment, when the dust hood 2 is installed on the gantry 11 of the engraving machine 1, the bottom inner wall of the suction chamber 21 is inclined upward in the direction away from the dust chamber 22.

[0043] Preferably, in this embodiment, a retractable dust cover (not shown in the drawings) is provided on the outer side of the portion of the sliding seat 421 and the lifting member 422 located inside the air intake chamber 21. This can prevent debris from affecting the movement of the baffle 41 and can guide the debris to be effectively discharged from inside the air intake chamber 21.

[0044] In some embodiments, the above-mentioned dust hood 2 may be adopted as follows: Figure 1 , Figure 6 The structure shown. See also... Figure 1 , Figure 6 The dust collection hood 2 is vertically slidably mounted on the gantry frame 11, and both ends of the dust collection hood 2 are rotatably equipped with support wheels 7 that are rolled on the machine tool. Vertically aligned guide columns are fixedly mounted on the side walls of the dust collection hood 2, and guide sleeves that slide in cooperation with the guide columns are installed on the side walls of the gantry frame 11. The sliding cooperation between the guide columns and guide sleeves reduces deformation of the dust collection hood 2. Simultaneously, support wheels 7 are rotatably mounted at both ends of the dust collection hood 2. Supported by the support wheels 7 on both sides of the loading table of the engraving machine 1, the dust collection hood 2 is effectively supported at both ends, improving the stability of its installation.

[0045] Preferably, in this embodiment, connecting plates are fixedly installed at both ends of the dust collection hood 2, and uprights are slidably mounted on the connecting plates. Two fasteners are threaded onto the uprights, located on opposite sides of the connecting plates. This allows adjustment of the relative position of the support wheel 7 and the dust collection hood 2 by adjusting the position of the two fasteners on the uprights, thereby adjusting the height of the dust collection hood 2 on the loading platform of the engraving machine 1. The height of the dust collection hood 2 can be adjusted according to the thickness of the material, thus enabling the dust collection hood 2 to achieve optimal dust collection performance.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
