Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood flooring processing technology, specifically to a wood flooring trimming device. Background Technology
[0002] Wood flooring refers to flooring made of wood. Wood flooring produced in China is mainly divided into six categories: solid wood flooring, engineered wood flooring, multi-layer composite flooring, bamboo flooring, and cork flooring, as well as the emerging wood-plastic composite flooring. In order to obtain the required shape during the processing of wood flooring, the edges and corners need to be cut. Currently, cutting and trimming devices are generally used for cutting and processing. After cutting, burrs will remain on the edges, which need to be trimmed with corresponding devices to make the edges smooth.
[0003] During high-speed cutting, existing trimming devices tend to cause sawdust and dust to adhere to the surface of the trimming wheel, which increases the friction between the tool and the wood flooring, gradually worsening the cutting effect. Overheating may even affect the tool's lifespan. Currently, most trimming machines can only trim one side of the wood flooring at a time. After completing one side, it is necessary to manually flip or reposition the machine before trimming the other side, which is cumbersome and time-consuming. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a wood floor trimming device includes a base 1, a mounting seat 2 slidably mounted on the top of the base 1, two sets of symmetrically distributed fixing frames 5 inside the base 1, the two sets of fixing frames 5 being symmetrically distributed about the mounting seat 2, trimming wheels 7 being rotatably mounted on each of the two sets of fixing frames 5, and mounting frames 8 being rotatably mounted on each of the two sets of fixing frames 5. Two sets of symmetrically distributed dust brushes 9 are fixedly mounted on the mounting frames 8, the dust brushes 9 being fitted with the trimming wheels 7, and dusting brushes 13 are provided on the fixing frames 5, the dusting brushes 13 being fitted with the dust brushes 9 respectively, and the dusting brushes 13 being slidably connected to the fixing frames 5 via sliders 16. A cam 17 is rotatably mounted. Two sets of symmetrically distributed clamping blocks 3 are slidably mounted on the mounting base 2. A mounting rod 18 is fixedly mounted inside the base 1. A first push rod 19 is slidably mounted inside the mounting rod 18. A second push rod 20 is slidably mounted inside the first push rod 19. The end of the second push rod 20 away from the mounting rod 18 is fixedly connected to the right end of the mounting base 2. A gear 10 is sleeved below the mounting bracket 8. A rack 11 is slidably mounted inside the fixing bracket 5. A cylinder 12 is fixedly mounted inside the fixing bracket 5. The rack 11 is fixedly connected to the output end of the piston rod of the cylinder 12. The rack 11 meshes with the gear 10. A slide rod 14 is fixedly mounted on the fixing bracket 5. The slider 16 and the slide rod 14 are slidably connected. Two sets of symmetrically distributed springs 15 are sleeved on the slide rod 14. The two ends of the two sets of springs 15 are fixedly connected to the slider 16 and the fixing frame 5, respectively. The cam 17 is fitted to the slider 16. During the operation of the trimming wheel 7, it scrapes against the edge of the wooden floor, and a large amount of sawdust or dust will adhere to the surface. At the same time, the dust brush 9, which is in contact with the trimming wheel 7 during the operation, will clean the sawdust and dust adhering to the surface of the trimming wheel 7, so as to avoid a decrease in cutting efficiency and ensure that the trimming wheel 7 continues to maintain the best working condition. After a set of dust brushes 9 has been used for a period of time, the cylinder 12 in the fixing frame 5 carries The sliding rack 11, in conjunction with the gear 10, causes the mounting bracket 8 to rotate the two sets of dust brushes 9 by 180 degrees, completing the position exchange between the two sets of dust brushes 9. When the dust brush 9 after work corresponds to the dust brush 13, the motor on the fixed bracket 5 drives the cam 17 to rotate, which, in conjunction with the slide rod 14 and the spring 15, causes the slider 16 to drive the dust brush 13 to vibrate up and down on the fixed bracket 5. The dust brush 13 and the dust brush 9 in contact with it scrape each other, forcing the dust brush 9 to shake, cleaning the residue accumulated on the dust brush 9, facilitating the subsequent replacement of the dust brush 9, extending the effective cleaning cycle of the dust brush 9, and reducing manual intervention.
[0023] like Figure 2 and Figure 5As shown, the mounting base 2 is equipped with a bidirectional screw 4, with both ends of the bidirectional screw 4 passing through the mounting base 2 and rotatably connected to the mounting base 2 via rolling bearings. Both ends of the bidirectional screw 4 pass through two sets of clamping blocks 3 and are threadedly connected to the two sets of clamping blocks 3 respectively. The base 1 is equipped with a bidirectional lead screw 6, with both ends of the bidirectional lead screw 6 passing through the base 1 and rotatably connected to the base 1 via rolling bearings. Both ends of the bidirectional lead screw 6 pass through two sets of fixing brackets 5 and are threadedly connected to the two sets of fixing brackets 5 respectively. A screw 21 is rotatably installed inside the mounting rod 18, passing through the first push rod 19 and threadedly connected to the first push rod 19. A screw tube 23 is rotatably installed inside the first push rod 19, passing through the second push rod 20 and threadedly connected to the second push rod 20. Two sets of axially extending symmetrical keyways 22 are formed on the surface of the screw 21. Two sets of symmetrically distributed key blocks 24 are provided inside the screw tube 23, with the key blocks 24 corresponding to the keyways 22. The screw tube 23 is connected to the keyways 24 via the key blocks 24. 22 is longitudinally slidably connected to screw 21. The rotation of the bidirectional screw 4 on the mounting bracket 8 can adjust the distance between the two sets of clamping blocks 3, thus fixing different types of wood flooring. According to the width of the wood flooring, the distance between the two sets of fixing brackets 5 and the distance between the two sets of trimming wheels 7 can be adjusted using the bidirectional lead screw 6 in the base 1, so that the two sets of trimming wheels 7 are synchronously attached to the two sides of the wood flooring waiting to be trimmed. During the rotation of screw 21 driven by the motor in the mounting rod 18, the first push rod 19 slides in the mounting rod 18. Under the action of key block 24 and keyway 22, the screw tube 23 rotates synchronously with screw 21. Then, under the limiting action of the first push rod 19, the second push rod 20 slides in the first push rod 19, pushing the mounting base 2 and the wood flooring fixed on the mounting base 2 at a uniform speed. The two sets of trimming wheels 7 are used to synchronously complete the double-sided trimming of the wood flooring, improving the efficiency of the wood flooring trimming work.
[0024] This utility model provides a wood floor trimming device. The specific working principle is as follows: During operation, the trimming wheel 7 scrapes against the edge of the wood floor, causing a large amount of sawdust or dust to adhere to its surface. Simultaneously, the dust-sweeping brush 9, which is in contact with the trimming wheel 7, cleans the sawdust and dust adhering to its surface, preventing a decrease in cutting efficiency and ensuring the trimming wheel 7 maintains optimal working condition. After a period of use, the cylinder 12 in the fixing frame 5 drives the rack 11 to slide, which, in conjunction with the gear 10, causes the mounting frame 8 to rotate the two sets of dust-sweeping brushes 9 by 180 degrees, completing the position exchange between the two sets of dust-sweeping brushes 9. When the dust-sweeping brush 9 aligns with the duster 13 after operation, the motor on the fixing frame 5 drives the cam 17 to rotate, which, in conjunction with the slide rod 14 and spring 15, causes the slider 16 to drive the duster 13 to vibrate up and down on the fixing frame 5. The duster 13 and the dust-sweeping brush 9 in contact scrape against each other, forcing the dust-sweeping brush 9 to shake, thus cleaning the residue accumulated on the dust-sweeping brush 9 and facilitating its operation. The subsequent replacement of the dust brush 9 extends its effective cleaning cycle and reduces manual intervention. The rotation of the bidirectional screw 4 on the mounting bracket 8 can adjust the distance between the two sets of clamping blocks 3, enabling the fixing of different types of wood flooring. According to the width of the wood flooring, the distance between the two sets of fixing brackets 5 and the distance between the two sets of trimming wheels 7 can be adjusted using the bidirectional lead screw 6 in the base 1, so that the two sets of trimming wheels 7 can synchronously fit with the two sides of the wood flooring waiting to be trimmed. During the rotation of the screw 21 driven by the motor in the mounting rod 18, the first push rod 19 slides in the mounting rod 18. Under the action of the key block 24 and the keyway 22, the screw tube 23 rotates synchronously with the screw 21. Then, under the limiting action of the first push rod 19, the second push rod 20 slides in the first push rod 19, pushing the mounting base 2 and the wood flooring fixed on the mounting base 2 at a uniform speed. The two sets of trimming wheels 7 synchronously complete the double-sided trimming of the wood flooring, improving the efficiency of the wood flooring trimming work.
