Description

Technical Field

[0001] The invention relates to the technical field of wood floor processing, and in particular to a wood floor grooving device and a grooving method thereof. Background Art

[0002] Grooving technology is a critical link in the manufacture and installation of wooden floors. It not only affects the tightness and flatness of the floor splicing, but also affects the adaptability of the floor to environmental changes. It is one of the important processes to ensure the beauty, stability and long service life of wooden floors. The depth of the groove is usually to partially penetrate the wood and stop after reaching a certain depth to ensure the stability and strength of the floor structure. This incompletely penetrating groove design can achieve a firm connection between the floors without weakening the overall structure of the floor, maintaining the integrity and durability of the floor.

[0003] In the existing wooden floor grooving device, although the grooving method has evolved from a single-line to a three-axis movable grooving tool to adapt to more complex and changeable grooving requirements, such as arc grooving and multi-point grooving on the back of the wooden floor, when the grooving tool moves flexibly in the three-axis direction, the distance between its grooving point and the dust suction port at a fixed position changes dynamically. This change will cause the wood chips and dust generated in the grooving process to not be effectively removed in time when the tool moves to a position away from the dust suction port. The accumulation of wood chips and dust will not only hinder the normal operation of the grooving tool and reduce the processing accuracy, but more importantly, when these accumulations come into contact with the high-speed rotating grooving tool, friction heat will be generated to form local high temperature, which will not only accelerate the wear of the tool and reduce its service life, but more seriously, the high temperature will cause thermal damage to the wooden floor material. Based on this, the present invention purposely provides a wooden floor grooving device and a grooving method thereof, in which the dust suction system can efficiently and timely remove wood chips and dust under the premise of dynamic changes in the grooving point position.

[0013] Beneficial effects of the present invention: 1. In the present invention, a telescopic tube is slidably sleeved on the dust suction tube, and a scraper is arranged at the bottom of the telescopic tube, so that when the wooden floor is in the grooving position, the scraper always abuts against the surface of the wooden floor. When the three-axis displacement component drives the grooving tool component to accurately groove the top surface of the wooden floor, it will drive the telescopic tube to move synchronously through the linkage component to ensure that the relative distance between the suction end of the telescopic tube and the grooving position of the grooving tool component is constant, thereby ensuring the consistency of dust suction efficiency and avoiding the attenuation of suction force caused by distance change. At the same time, when the grooving tool component grooves different positions on the wooden floor, when the telescopic tube moves synchronously, the scraper will scrape and clean the top surface of the wooden floor in real time, effectively removing the debris left on the board surface during the last grooving, ensuring that the debris can be sucked into the telescopic tube in time, so that during the entire grooving process, the working area of ​​the grooving tool component is always in a relatively clean state, significantly reducing the accumulation of debris, and improving the grooving accuracy and processing efficiency; 2. In the present invention, when the slotting tool assembly slots the wooden floor, the scraper always abuts against the wooden floor, and the scraper can synchronously scrape and clean the wooden floor surface as the telescopic tube moves, and the scraper also applies pressure to the wooden floor, and cooperates with the clamping assembly to further improve the stability of the wooden floor when being slotted, thereby improving the slotting accuracy; 3. In the present invention, a cold air chamber is added to the suction end of the telescopic tube. The cold air blown out of the cold air chamber can, on the one hand, disperse the wood chips and dust generated by the grooving to avoid the concentration of impurities at the grooving location, and the blown out wind can lift up the impurities scraped off by the scraper, making it easier to be sucked into the telescopic tube. On the other hand, the cold air can directly cool the grooving location to avoid overheating of the grooving tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 10 As shown, the present invention is a wooden floor grooving device, comprising: A processing table 1 is provided with a slotting tool assembly 11, a linkage assembly 12 and a locking assembly 13 on the top thereof; a lifting plate 2 is provided between the processing table 1 and the slotting tool assembly 11; a wooden floor 3 is placed on the top of the lifting plate 2 through a limiting assembly, and the lifting plate 2 is driven to be lifted and lowered by a first telescopic member fixedly installed in the processing table 1; There are two carrying frames 8, both of which are fixedly mounted on the processing table 1, and the two carrying frames 8 are symmetrically arranged, and a three-axis moving assembly is arranged between the two carrying frames 8, and the three-axis moving assembly is used to drive the slotting tool assembly 11 to move; Dust suction pipes 4, two of which are fixedly mounted on the processing table 1 and arranged symmetrically, the connecting line of the two dust suction pipes 4 being perpendicular to the connecting line of the two bearing frames 8, the dust suction pipes 4 being connected to the dust suction device, the suction end of each dust suction pipe 4 being slidably sleeved with a telescopic pipe 5, the bottom edge of the suction end of each telescopic pipe 5 being fixedly mounted with a scraper 6, and the width of the suction end thereof being not less than the width of the wooden floor 3, when the lifting plate 2 rises to the highest horizontal height, the top surface of the wooden floor 3 thereon abuts against the scraper 6; and When the telescopic tube 5 is connected to the locking assembly 13, it is disconnected from the linkage assembly 12, and the two telescopic tubes 5 are driven by the locking assembly 13 to move toward each other; when the telescopic tube 5 is connected to the linkage assembly 12, it is disconnected from the locking assembly 13, and the suction ends of the two telescopic tubes 5 are both facing the contact point between the slotting tool assembly 11 and the wooden floor 3, and when the three-axis displacement assembly drives the slotting tool assembly 11 to move longitudinally and drives the slotting tool assembly 11 to move in a direction perpendicular to the sliding direction of the telescopic tube 5, the telescopic tube 5 remains stationary, and when the three-axis displacement assembly drives the slotting tool assembly 11 to move in a direction parallel to the sliding direction of the telescopic tube 5, it drives the telescopic tube 5 to move synchronously through the linkage assembly 12.

[0019] In one case of the present embodiment, the first telescopic member can be an electric cylinder, an electric telescopic rod and other components, and the dust collection equipment can be a single-machine bag dust collector, an industrial vacuum cleaner and other equipment, which are not specifically limited in the present embodiment; it should be noted that the slotting tool assembly 11 described in the present invention includes a motor, a rotary drill bit, an electrical control box, a clamp, etc., and the above components are all prior art, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0020] In practical application, if Figure 1 and Figure 2 As shown, the lifting plate 2 is lowered to a position where the wooden floor 3 can be installed by the first telescopic member, and the two telescopic tubes 5 are controlled to move to the farthest position by the locking assembly 13, and then the wooden floor 3 is fixed on the lifting plate 2 by the limiting assembly, and then Figure 3 As shown in FIG. 1 , the lifting plate 2 is driven up by the first telescopic member until the top edge of the wooden floor 3 abuts against the scraper 6, and then the vacuum device is turned on. The suction force generated by the vacuum device forms a negative pressure in the telescopic tube 5 through the vacuum tube 4. At this time, the debris near the suction end of the telescopic tube 5 will be sucked in. Then, as shown in FIG. Figure 4 As shown, the two telescopic tubes 5 are controlled by the locking assembly 13 to move toward the middle of the wooden floor 3 until the two scrapers 6 are in contact. During this process, the scrapers 6 are always in contact with the top surface of the wooden floor 3, so that the top surface of the wooden floor 3 can be cleaned once, and the scraped impurities will be sucked away by the telescopic tubes 5; Then Figure 5 As shown, the two telescopic tubes 5 are controlled to move away from each other by the locking assembly 13, so that the wooden floor 3 to be processed is leaked out between the two scrapers 6, and the connection between the telescopic tube 5 and the locking assembly 13 is released, so that the telescopic tube 5 is connected to the linkage assembly 12, and the suction end of the telescopic tube 5 is facing the slotting tool assembly 11. Finally, as shown in FIG. Figure 6 As shown, the slotting tool assembly 11 can be driven by the three-axis moving assembly to slot the top surface of the wooden floor 3. At the same time, when the three-axis displacement assembly drives the slotting tool assembly 11 to move longitudinally and drives the slotting tool assembly 11 to move along the sliding direction perpendicular to the telescopic tube 5, the telescopic tube 5 remains stationary. When the three-axis displacement assembly drives the slotting tool assembly 11 to move along the sliding direction parallel to the telescopic tube 5, it drives the telescopic tube 5 to move synchronously through the linkage assembly 12. Because the width of the suction end of the telescopic tube 5 is not less than the width of the wooden floor 3, no matter where the slotting tool assembly 11 moves along the sliding direction perpendicular to the telescopic tube 5, the telescopic tube 5 can suck in the wood chips and dust generated during the slotting. In addition, during the movement of the telescopic tube 5, the scraper 6 will also scrape and clean the top surface of the wooden floor 3, scrape off the wood chips and dust adsorbed on the top surface of the wooden floor 3 that cannot be sucked in by the telescopic tube 5, so that they are all sucked in by the telescopic tube 5, or pushed into the already opened grooves, to avoid them being retained in the area to be slotted on the top surface of the wooden floor 3. The scraper 6 always abuts against the upper wooden floor 3, and can exert pressure on the wooden floor 3, thereby improving the stability of the wooden floor 3 when grooving; The telescopic tube 5 is slidably sleeved on the dust suction tube 4, and a scraper 6 is arranged at the bottom of the telescopic tube 5, so that when the wooden floor 3 is in the grooving position, the scraper 6 always abuts against the surface of the wooden floor 3. When the three-axis displacement component drives the grooving tool assembly 11 to accurately groove the top surface of the wooden floor 3, it will drive the telescopic tube 5 to move synchronously through the linkage assembly 12, ensuring that the relative distance between the suction end of the telescopic tube 5 and the grooving position of the grooving tool assembly 11 is constant, thereby ensuring the consistency of dust suction efficiency and avoiding the attenuation of suction force caused by distance change. At the same time, when the grooving tool assembly 11 grooves different positions on the wooden floor 3, when the telescopic tube 5 moves synchronously, the scraper 6 will scrape and clean the top surface of the wooden floor 3 in real time, effectively removing the debris left on the board surface during the last grooving, ensuring that the debris can be sucked into the telescopic tube 5 in time, so that during the entire grooving process, the working area of ​​the grooving tool assembly 11 is always in a relatively clean state, significantly reducing the accumulation of debris, and improving the grooving accuracy and processing efficiency.

[0021] like Figure 1-Figure 6As shown, as a preferred embodiment of the present invention, the three-axis displacement assembly includes a moving table 9 and a moving frame 10, the two moving tables 9 are respectively slidably installed in the carrying frame 8, and are driven to move by a first driving source fixedly installed on the carrying frame 8, and their moving direction is consistent with the sliding direction of the telescopic tube 5, the moving frame 10 is slidably installed between the two moving tables 9, and is driven to rise and fall by a second driving source built into the moving table 9, the slotting tool assembly 11 is slidably installed in the moving frame 10, and is driven to move by a third driving source fixedly installed on the moving frame 10, and the moving direction of the slotting tool assembly 11 is perpendicular to the moving direction of the moving table 9.

[0022] In one case of this embodiment, the first driving source, the second driving source and the third driving source can all be electric cylinders, electric telescopic rods and other components, and other mechanisms that can achieve linear reciprocating motion can also be selected, and this embodiment does not make specific limitations here.

[0023] In actual application of this embodiment, when the third driving source drives the slotting tool assembly 11 to move in the moving frame 10, the slotting tool assembly 11 moves along a direction perpendicular to the sliding direction of the telescopic tube 5, and when the second driving source drives the moving frame 10 to rise and fall on the moving platform 9, the slotting tool assembly 11 rises and falls synchronously, and when the first driving source drives the moving platform 9 to move in the carrying frame 8, the slotting tool assembly 11 will move synchronously along a direction parallel to the sliding direction of the telescopic tube 5. In this way, through the coordinated work of the three driving sources, the slotting tool assembly 11 can move freely in three-dimensional space and realize its positioning at any position on the top surface of the wooden floor 3. This positioning capability enables the slotting tool assembly 11 to accurately design slots on the top surface of the wooden floor 3.

[0024] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, the linkage assembly 12 includes a vertical plate 501 and a through hole 1001. The vertical plate 501 is fixedly mounted on the top surface of the telescopic tube 5 and is located at the suction end of the telescopic tube 5. The through hole 1001 is opened on the moving frame 10. When the vertical plate 501 is located below the through hole 1001 and the second driving source drives the moving frame 10 to descend, the vertical plate 501 is inserted into the through hole 1001.

[0025] In practical application, if Figure 4 As shown in FIG. 1 , when the second driving source drives the moving frame 10 to rise to the highest horizontal position in the moving platform 9, the vertical plate 501 on the telescopic tube 5 is located below the moving frame 10, so that the telescopic tube 5 can pass through the moving frame 10. Figure 5As shown, when the vertical plate 501 is located below the through hole 1001, the second driving source drives the moving frame 10 to descend, and the vertical plate 501 will be inserted into the through hole 1001 to form a snap-fit ​​fixation. At this time, when the moving frame 10 moves left and right, it will also drive the telescopic tube 5 to move left and right accordingly, so that the distance between the telescopic tube 5 and the slotting tool assembly 11 is constant, avoiding the problem that the slotting tool assembly 11 moves away from the suction end of the telescopic tube 5, resulting in reduced suction, and the wood chips and dust cannot be sucked in and cleaned in time.

[0026] like Figure 8-Figure 10 As shown, as a preferred embodiment of the present invention, the locking assembly 13 includes an extension plate 502, a bidirectional screw rod 14, a slider 15 and a U-shaped block 16. The extension plate 502 is fixedly installed on the telescopic tube 5, and it faces the supporting frame 8. The bidirectional screw rod 14 is rotatably installed in the supporting frame 8, and it is driven to rotate by an output source fixedly installed on the supporting frame 8. The two sliders 15 are slidably installed in the supporting frame 8, and the two sliders 15 are threadedly connected to both ends of the bidirectional screw rod 14. The U-shaped block 16 is fixedly connected to the movable end of the second telescopic member fixedly installed in the slider 15. When the second telescopic member contracts, the U-shaped block 16 separates from the extension plate 502. When the slider 15 moves until the U-shaped block 16 is aligned with the extension plate 502, the second telescopic member extends, and the U-shaped block 16 is clamped and fixed to the extension plate 502.

[0027] In one case of this embodiment, the second telescopic member can be an electric cylinder, an electric telescopic rod and other components, and can also be other mechanisms capable of realizing linear reciprocating motion. The output source can be a servo motor, a servo motor and other components, and this embodiment does not make any specific limitations here.

[0028] When the U-shaped block 16 is aligned with the extension plate 502, the second telescopic member is extended, and the U-shaped block 16 is fixedly connected to the extension plate 502. At this time, the output source drives the bidirectional screw rod 14 to rotate. Since the bidirectional screw rod 14 is threadedly connected to the slider 15, and the characteristics of the bidirectional screw rod 14 determine that it can drive the sliders 15 at both ends to move toward each other, and then drive the telescopic tube 5 to move synchronously with the slider 15 through the connection between the U-shaped block 16 and the extension plate 502. In this way, the slider 15 can be actively moved from the edge of the wooden floor 3 to the middle of the wooden floor 3, so that before the wooden floor 3 is grooved, the top surface of the wooden floor 3 is cleaned once, and it can be moved to the connection between the telescopic tube 5 and the linkage assembly 12, so that the telescopic tube 5 and the linkage assembly 12 and the locking assembly 13 can be switched.

[0029] like Figure 8-Figure 9As shown, as a preferred embodiment of the present invention, a cold air chamber 7 is provided at the suction end of the telescopic tube 5, and the cold air chamber 7 is connected to an external cold air device through a connecting pipe 701, and its outlet end faces the contact point between the grooving tool assembly 11 and the wooden floor 3.

[0030] In one case of this embodiment, the external cold air device may be a cold air duct system, an air conditioning system, etc., which is not specifically limited in this embodiment.

[0031] In actual application, this embodiment is provided with a cold air chamber 7 at the suction end of the telescopic tube 5. The cold air blown out of the cold air chamber 7 can, on the one hand, disperse the wood chips and dust generated by the grooving to avoid the concentration of impurities at the grooving location, and the blown out wind can lift up the impurities scraped off by the scraper 6 to make it easier to be sucked into the telescopic tube 5. On the other hand, the cold air can directly cool the grooving location to avoid overheating of the grooving tool.

[0032] like Figure 2 As shown, as a preferred embodiment of the present invention, the limiting assembly includes a long plate 201 and a short plate 202, the two long plates 201 and the two short plates 202 are fixedly installed on the top surface of the lifting plate 2, and the wooden floor 3 is located between the two long plates 201 and the two short plates 202. When the scraper 6 abuts against the top surface of the wooden floor 3, the height of the long plate 201 is flush with the height of the scraper 6, and the short plate 202 is located below the scraper 6.

[0033] In actual application of this embodiment, the wooden floor 3 can be installed by directly placing it between two long boards 201 and two short boards 202, and when the scraper 6 abuts against the top surface of the wooden floor 3, the height of the long board 201 is flush with the height of the scraper 6, and the short board 202 is located below the scraper 6. The long board 201 can prevent impurities scraped off by the scraper 6 from leaking out from the edge of the wooden floor 3, while the short board 202 avoids hindering the movement of the scraper 6.

[0034] like Figure 2-Figure 7 As shown, as a preferred embodiment of the present invention, a push rod 17 is fixedly installed on the processing table 1. When the lifting plate 2 is lowered to the lowest horizontal height, the push rod 17 passes through the lifting plate 2 and its height is not lower than the height of the long plate 201.

[0035] In practical application, if Figure 7 As shown, when the grooved wooden floor 3 descends together with the lifting plate 2, the push rod 17 will penetrate the lifting plate 2 to lift up the wooden floor 3, so that the wooden floor 3 can be easily removed and the problem of the wooden floor 3 being stuck between the long board 201 and the short board 202 and being inconvenient to remove can be avoided.

[0036] See also Figure 1-Figure 10As shown, the present invention is a grooving method for a wooden floor grooving device, the method is applied to a wooden floor grooving device as described in the above embodiment, and the method comprises the following steps: Step S1: Connect the telescopic tube 5 to the locking assembly 13, and control the two telescopic tubes 5 to move to the farthest position through the locking assembly 13; Step S2: The lifting plate 2 is controlled to descend by the first telescopic member, and then the wooden floor 3 is fixed on the top surface of the lifting plate 2 by the limit assembly, and the side to be grooved is ensured to face upward, and then the lifting plate 2 is controlled to rise by the first telescopic member, so that the edge of the top surface of the wooden floor 3 abuts against the scraper 6; Step S3: Turn on the vacuum cleaner and control the two telescopic tubes 5 to move from the edge of the wooden floor 3 to the middle of the wooden floor 3 through the locking assembly 13 until the two scrapers 6 are in contact; Step S4: Control the two telescopic tubes 5 to move to the moving frame 10 through the locking assembly 13, then release the connection between the telescopic tubes 5 and the locking assembly 13, and then connect the telescopic tubes 5 to the linkage assembly 12, at which time the suction end of the telescopic tubes 5 faces the slotting tool assembly 11; Step S5: The slotting tool assembly 11 is driven by the three-axis moving assembly to slot the top surface of the wooden floor 3. At the same time, the linkage assembly 12 is used to drive the telescopic tubes 5 on both sides to cooperate with the slotting tool assembly 11 to ensure that the slotting position of the slotting tool assembly 11 and the suction end of the telescopic tube 5 are at a constant distance. During the movement of the telescopic tube 5, the scraper 6 is used to scrape and clean the top surface of the wooden floor 3 to prevent wood chips and dust from being adsorbed on the top surface of the wooden floor 3, and then the wood chips and dust generated by the slotting are sucked in through the telescopic tube 5; Step S6: After the grooving of the wooden floor 3 is completed, the wooden floor 3 can be removed by lowering the first telescopic member, and the telescopic tube 5 and the linkage assembly 12 are disconnected.

[0037] Working principle of the present invention: The above embodiment of the present invention provides a wooden floor grooving device and a grooving method thereof, wherein the two telescopic tubes 5 are controlled to move away from each other by a locking assembly 13, so that the wooden floor 3 to be processed leaks out between the two scrapers 6, and the connection between the telescopic tube 5 and the locking assembly 13 is released, so that the telescopic tube 5 is connected to the linkage assembly 12, at which time the suction end of the telescopic tube 5 faces the grooving tool assembly 11, and the grooving tool assembly 11 is driven by the three-axis moving assembly to groove the top surface of the wooden floor 3, and at the same time, when the three-axis displacement assembly drives the grooving tool assembly 11 to move longitudinally and drives the grooving tool assembly 11 to move along a direction perpendicular to the sliding direction of the telescopic tube 5, the telescopic tube 5 does not move, and when the three-axis displacement assembly When the slotting tool assembly 11 is driven to move along the sliding direction parallel to the telescopic tube 5, it drives the telescopic tube 5 to move synchronously through the linkage assembly 12. Because the width of the suction end of the telescopic tube 5 is not less than the width of the wooden floor 3, no matter where the slotting tool assembly 11 moves to along the sliding direction perpendicular to the telescopic tube 5, the telescopic tube 5 can suck in the wood chips and dust generated during slotting. In the process of moving the telescopic tube 5, the scraper 6 will also scrape and clean the top surface of the wooden floor 3, and scrape off the wood chips and dust adsorbed on the top surface of the wooden floor 3 that cannot be sucked in by the telescopic tube 5, so that they are all sucked in by the telescopic tube 5, or pushed into the already opened groove, to avoid them staying in the area to be slotted on the top surface of the wooden floor 3.
