Description

Technical Field

[0001] This utility model relates to the field of grooving machine technology, and in particular to a chip removal device for a grooving machine. Background Technology

[0002] During the grooving process of wooden boards, depending on the board size, processing accuracy, and shape requirements, the boards to be processed are often placed on the grooving machine's worktable in either a vertical or horizontal position. In these two processing scenarios, the location of chip generation, the splash path, and the accumulation area differ significantly, posing specific requirements for the adaptability of the chip removal device.

[0003] Existing chip removal devices for grooving machines are mostly integrated fixed structures, typically designed with chip removal channels and negative pressure adsorption structures adapted to only one processing posture. When switching processing scenarios, the original chip removal device cannot effectively cover the processing area under the new posture, and the negative pressure adsorption force cannot accurately act on the point where fine chips are generated. As a result, a large amount of fine chips cannot be removed in time, which not only scatter and accumulate on the worktable and in the gaps of the equipment, affecting the positioning accuracy of subsequent processing, but may also spread as dust with airflow, endangering the respiratory health of operators.

[0004] Some chip removal devices that attempt to accommodate multiple processing scenarios suffer from complex negative pressure connection structures and lack flexible switching capabilities between the chip removal channel and the negative pressure equipment. Furthermore, because the connections often rely on bolts and other fastening methods, disassembly with specialized tools is required to clean the accumulated sawdust within the chip removal channel, making the process cumbersome and time-consuming. Over time, fine chips adhering to the inner walls of the channel can easily cause blockages, further weakening the chip removal effect and hindering daily maintenance and production efficiency improvements.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0020] Please see Figures 1 to 2 As shown, this utility model provides a chip removal device for a grooving machine, which includes a positioning plate 1, a support plate 2, and a negative pressure connecting pipe 3; The positioning plate 1 is vertically fixed on the worktable 7 of the grooving machine and is used to stop and limit the wood board to be processed; the side of the positioning plate 1 that contacts the wood board to be processed is provided with a plurality of negative pressure grooves 11, and the plurality of negative pressure grooves 11 converge and connect to the first negative pressure hole 12. The support plate 2 is detachably installed on the positioning plate 1. The support plate 2 is provided with a second negative pressure hole 21. One end of the second negative pressure hole 21 is sealed and connected to a retractable chip removal tube 4. The negative pressure connecting pipe 3 is connected to the external negative pressure chip removal equipment, and can be detachably connected to either the first negative pressure hole 12 or the second negative pressure hole 21. When the wood board to be processed is placed vertically for processing, the negative pressure connecting pipe 3 is detachably connected to the first negative pressure hole 12. The wood board to be processed is attached to the positioning plate 1 to block the negative pressure groove 11 and the first negative pressure hole 12, forming a negative pressure environment, so that the fine debris generated during the grooving process is sucked away and removed in sequence through the negative pressure groove 11, the first negative pressure hole 12 and the negative pressure connecting pipe 3. When the wooden board to be processed is placed horizontally for processing, the negative pressure connecting pipe 3 is detachably connected to the second negative pressure hole 21. The chip removal pipe 4 extends and moves downwards close to the wooden board to be processed to form a negative pressure environment, so that the fine chips generated by the grooving process are sucked away and removed in sequence through the chip removal pipe 4, the second negative pressure hole 21 and the negative pressure connecting pipe 3.

[0021] In actual processing, when the wood board to be processed is placed vertically, the support plate 2 is removed from the positioning plate 1 to avoid the support plate 2 affecting the placement and feeding movement of the wood board.

When the wood board to be processed is placed horizontally, the support plate 2 is installed on the positioning plate 1, and the connection between the negative pressure connecting pipe 3 and the first negative pressure hole 12 is disconnected. Then, the negative pressure connecting pipe 3 is connected to the second negative pressure hole 21, and the chip removal pipe 4 is pulled down and brought close to the wood board to be processed. The external negative pressure chip removal equipment is turned on to suck away and clean the fine chips generated during the grooving process. The chip removal device of this grooving machine can flexibly adapt to two different processing positions of wooden boards, vertical and horizontal. It can meet the needs of different processing scenarios without changing the entire chip removal structure, thus improving adaptability. At the same time, the fine chips generated in both processing states can be directly sucked away through the corresponding negative pressure channels, effectively preventing the fine chips from scattering and accumulating, making chip removal more timely. Furthermore, the selective detachable connection of the negative pressure connecting pipe 3, combined with the overall structural design, makes subsequent cleaning and maintenance operations more convenient, further ensuring the cleanliness of the processing environment and improving work efficiency.

[0022] In this embodiment, the grooving machine selected is the Ma's MX5117B grooving machine. The positioning plate 1 is fixed to the worktable 7 of the grooving machine by welding or screws. Several negative pressure grooves 11 are arranged at intervals from top to bottom. The length direction of the negative pressure grooves 11 is parallel to the worktable 7 of the grooving machine. The first negative pressure hole 12 is located at one end of the positioning plate 1. The diameter of the first negative pressure hole 12 is greater than the distance between the groove walls of the two negative pressure grooves 11 at the highest and lowest points, so that all negative pressure grooves 11 are connected to the first negative pressure hole 12. The support plate 2 and the positioning plate 1 are detachably plugged in. When it is necessary to place the wooden board vertically for grooving, the support plate 2 is removed from the positioning plate 1 to avoid interfering with the placement and feeding of the wooden board to be processed. The main body of the negative pressure connecting pipe 3 adopts a telescopic corrugated pipe 41. Its flexibility and telescopicity are conducive to changing the installation position and pipeline layout, improving adaptability. The chip removal tube 4 is attached to the wall of the second negative pressure hole 21 and sealed with glue to prevent air leakage and affect the negative pressure effect.

[0023] Please see Figures 1 to 3As shown, a snap-fit ​​plate 5 is movably sleeved on the outer side of the negative pressure connecting pipe 3. A first clearance groove 51 is provided on the wall of the hole in the snap-fit ​​plate 5. A first positioning protrusion 31 is provided on the outer side of the negative pressure connecting pipe 3. The first clearance groove 51 allows the first positioning protrusion 31 to pass through, thereby adjusting the position of the snap-fit ​​plate 5 on the negative pressure connecting pipe 3. The end of the first positioning protrusion 31 is used to stop and limit the snap-fit ​​plate 5. In this embodiment, the negative pressure connecting pipe 3 and the first positioning protrusion 31 are an integral structure. Two retaining rings 32, also integrally formed with the negative pressure connecting pipe 3, are also spaced apart on the outer side of the negative pressure connecting pipe 3. The first positioning protrusion 31 is fixedly connected to one of the retaining rings 32 and located between the two retaining rings 32. The snap-fit ​​plate 5 is located between the two retaining rings 32. The snap-fit ​​plate 5 has a square outer shape and a round inner shape, and the first clearance groove 51 is provided on the wall of the hole. When connecting the negative pressure connecting pipe 3 to the first negative pressure hole 12 or the second negative pressure hole 21, first align the first positioning protrusion 31 with the first clearance groove 51, move the snap-fit ​​plate 5 so that the first positioning protrusion 31 enters the first clearance groove 51, and then insert the snap-fit ​​plate 5 into the first mounting groove 13 or the second mounting groove 22 so that the negative pressure connecting pipe 3 is aligned with the first negative pressure hole 12 or the second negative pressure hole 21. Push the negative pressure connecting pipe 3 so that the first positioning protrusion 31 exits the first clearance hole and the end of the negative pressure connecting pipe 3 is inserted into the first negative pressure hole 12 or the second negative pressure hole 21. Rotate the negative pressure connecting pipe 3 at a certain angle so that the end of the first positioning protrusion 31 abuts against the snap-fit ​​plate 5, thereby achieving axial positioning of the negative pressure connecting pipe 3 and ensuring that the hole wall of the first negative pressure hole 12 or the second negative pressure hole 21 radially positions the negative pressure connecting pipe 3, so as to prevent the negative pressure connecting pipe 3 from deviating from the first negative pressure hole 12 or the second negative pressure hole 21 and affecting the negative pressure chip removal effect.

The openings of the two second mounting grooves 22 are arranged opposite each other and are equidistant from the center of the second negative pressure hole 21, so as to accurately align the negative pressure connecting pipe 3 with the second negative pressure hole 21 when it is installed.

[0026] Please see Figures 1 to 2 As shown, the lower end of the positioning plate 1 is provided with a through hole 14. The through hole 14 is used for the working part of the grooving machine cutter 6 to pass through the positioning plate 1 to perform grooving on the wood to be processed. In this embodiment, the grooving machine cutter 6 is disc-shaped, and the length of the through hole 14 is equal to the diameter of the cutter 6, to prevent the working part of the cutter 6 from contacting the hole wall of the through hole 14 when rotating, thereby preventing damage to the cutter 6 or the positioning plate 1. The length of the working part of the cutter 6 protruding from the positioning plate 1 is equal to the required groove depth of the wood to be processed. The positioning plate 1 abuts against the wood to be processed for limiting, which can make the grooving depth more accurate.

[0027] Please see Figure 2 As shown, the positioning plate 1 has two third mounting grooves 15 on the side away from the negative pressure groove 11, and the two third mounting grooves 15 are located above the through hole 14. In this embodiment, the third mounting grooves 15 and the positioning plate 1 are integrally formed. The openings of the two third mounting grooves 15 are arranged opposite each other and are equidistant from the center of the through hole 14, so that the chip removal tube 4 of the support plate 2 corresponds to the working part of the tool 6, which is beneficial for adsorbing and removing fine chips generated during processing.

[0028] Please see Figures 2 to 3 As shown, the bottom surface of the support plate 2 is provided with an insert plate 23, and the two third mounting slots 15 respectively accommodate the two side edges of the insert plate 23 to realize the detachable installation of the support plate 2 and the positioning plate 1. In this embodiment, the insert plate 23 and the support plate 2 are fixed by welding. The insert plate 23 is perpendicular to the support plate 2 and parallel to the positioning plate 1. The width of the insert plate 23 is equal to the distance between the bottom walls of the two third mounting slots 15. The detachable insertion of the insert plate 23 into the third mounting slots 15 realizes the detachable connection between the support plate 2 and the positioning plate 1, improving the flexibility and adaptability of the device.

[0029] Please see Figures 1 to 3As shown, the chip removal pipe 4 includes a retractable corrugated pipe 41 and a flared mouth 42.
