Description

Technical Field

[0001] This invention belongs to the field of floor cutting technology, and more specifically, relates to a floor cutting device and its usage method. Background Technology

[0002] Epoxy flooring is a high-strength, wear-resistant, and aesthetically pleasing flooring option. It boasts advantages such as seamless construction, solid texture, excellent chemical resistance, corrosion resistance, dust resistance, easy maintenance, and low maintenance costs. Therefore, epoxy floor paint is commonly used for flooring construction in emergency exits, parking lots, shopping malls, factories, and other similar locations.

[0003] In the construction of epoxy self-leveling flooring, the cutting process is a crucial step in ensuring the flatness and aesthetics of the floor. During cutting, it is usually necessary to adjust the distance between the two cutting blades and their height. Effectively ensuring the stability of this adjustment is essential for guaranteeing cutting quality. However, when using existing cutting devices for adjustment, inaccurate blade adjustment or unstable blade movement during lifting and lowering often occurs. This not only affects cutting accuracy but may also damage the equipment itself. Furthermore, the cutting blade may vibrate vertically or horizontally during lifting and lowering, resulting in an uneven cut surface or even damaging the already laid flooring material. Summary of the Invention

After cutting is completed, all motors are turned off and the cutting operation is stopped.

[0027] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0028] (1) This invention provides a floor cutting device. By optimizing the structure of the floor cutting device, especially optimizing the spacing and height adjustment structure of the cutting blades, the stability of the spacing and height adjustment of the cutting blades can be effectively improved. This solves the problems of unstable lifting and lowering of the cutting blades and easy shaking that exist in traditional cutting devices. In particular, it can effectively prevent the cutting blades from shaking up and down or shifting left and right during the lifting process, thus helping to ensure the flatness of the cutting surface and the integrity of the floor material.

[0029] (2) In this invention, the outer plate is slidably engaged with the base on both sides by a sliding plate. The outer plate and the sliding plates at both ends together form an integral frame. The cutting blade is connected to the side column through the integral frame. This can improve the structural stability and strength of the overall device, thus improving the stability of floor cutting. On the other hand, the outer plate is moved by sliding the two sliding plates. Through the setting of the telescopic sliding connection unit and structural optimization, the stability of the cutting blade during cutting can be further improved. In particular, the cooperation of the sleeve plate, support rod and limit spring can effectively prevent the cutting blade from shaking or shifting when adjusting the height of the cutting blade. At the same time, it can also reduce the risk of damage to the equipment due to shaking.

[0030] (3) The present invention further optimizes the design of the spacing adjustment structure of the cutting blade. By driving the active gear with the toothed edge on the slide plate through the frequency conversion motor, the spacing of the cutting blade can be precisely electrically adjusted. Compared with the existing manual or simple mechanical adjustment methods, the accuracy and stability of the spacing adjustment are significantly improved, avoiding errors caused by human factors, ensuring the cutting edge is flat, and improving the overall quality of the floor. At the same time, it can also reduce the workload of construction personnel to frequently adjust and repeatedly check the spacing of the cutting blade, which is conducive to improving construction efficiency.

[0031] (4) The present invention uses a lifting plate to drive the outer plate and the cutting blade to move up and down together. It utilizes the spiral transmission method of the threaded rod and the internal threaded groove, and is supplemented by the cooperation of the sliders on both sides of the lifting plate and the first slide groove, so as to ensure the smooth lifting of the lifting plate. The design of the limit spring and the sleeve plate can also provide stable support and buffer for the movable column, further ensuring the smoothness of the lifting process.

[0032] (5) When adjusting the spacing of the cutting blades, the telescopic sliding connection unit can slide telescopically along the movable groove. By the cooperation of the limiting slide strips on both sides of the moving plate and the limiting groove, not only can the stability of the cutting blade lifting adjustment be guaranteed, but also the stable movement of the cutting blades can be guaranteed when the spacing is adjusted, thereby accurately controlling the spacing between the two cutting blades.

Detailed Implementation

[0043] To further understand the content of this invention, it will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0045] like Figure 1 , Figure 2 As shown, this embodiment of the invention provides a floor cutting device, which includes a base 1, and two side columns 6 that are perpendicular to the base 1 and distributed in parallel on the top of the base 1; each of the two side columns 6 has an outer plate 8 on its opposite side, and two cutting blades 9 that are parallel to each other and symmetrically distributed are connected to the opposite side of the two outer plates 8, and the two cutting blades 9 are used to cut the two sides of the floor.

[0046] The two side pillars 6, facing away from each other, each have a sliding lifting plate 13 that can slide up and down along the side pillars 6. The lifting plate 13 is connected to a lifting drive unit. A movable plate 26 is slidably installed inside the outer plate 8. A retractable sliding connecting unit is located at one end of the lifting plate 13 near the outer plate 8. One end of the retractable sliding connecting unit is slidably installed inside the lifting plate 13, and the other end is fixedly connected to the movable plate 26. The cutting blade 9 is mounted on the movable plate 26. The lifting drive unit drives the lifting plate 13 to slide up and down along the side pillars 6, thereby causing the movable plate 26 to slide up and down inside the outer plate 8 via the retractable sliding connecting unit, which in turn drives the cutting blade to move up and down, achieving height adjustment. The combined effect of the lifting plate 13 and the movable plate 26 also helps improve the smoothness and stability of the cutting blade's lifting and lowering movement.

[0047] In this embodiment, the outer plate 8 is slidably engaged with the base 1 on both sides by a sliding plate 30. The sliding plate 30 is driven by a spacing adjustment drive unit, which moves the outer plate 8 and the cutting blade 9 along the direction of approaching or moving away from the side column 6. On the one hand, the sliding plates 30 on both sides of the outer plate 8 and the outer plate 8 form an integral frame, which can effectively improve the stability of the cutting blade installation and improve the structural stability and strength of the entire device. On the other hand, the two sliding plates 30 are driven by the spacing adjustment drive unit to slide along the base 1, thereby moving the outer plate 8 and the cutting blade 9 together along the direction of approaching or moving away from the side column 6, which can also effectively improve the stability of the cutting blade spacing adjustment and prevent skewing.

[0048] As a preferred embodiment of the present invention, such as Figure 3 , Figure 7 As shown, the lifting plate 13 has a movable groove 17 machined on the side near the outer plate 8. The retractable sliding connection unit is retractably and slidably installed in the movable groove 17, and the retractable sliding connection unit includes:

[0049] The movable column 18 has one end that can be slidably installed in the movable groove 17 and has a support groove 19 machined at that end. The other end of the movable column 18 extends to the outside of the movable groove 17 and is connected to the connecting plate 23. The connecting plate 23 is fixedly connected to the movable plate 26.

[0050] Support rod 20, one end of which is fixedly installed on the inner wall of the movable groove 17, and the other end of which is slidably installed in the support groove 19 on the movable column 18;

[0051] A sleeve 21 is fitted over the outside of the support rod 20 and is in contact with one end of the movable column 18 located in the movable groove 17; a limit spring 22 is also fitted over the outside of the support rod 20 between the sleeve 21 and the inner wall of the movable groove 17.

[0052] When the spacing of the cutting blades is adjusted, the movable column 18 is pushed to slide along the movable groove 17 by the outer plate 8. The stability of the sliding of the movable column 18 can be further improved by the setting and cooperation of the support rod 20 and the sleeve plate 21. In addition, when the height of the cutting blades is adjusted, the design of the limit spring and the sleeve plate can provide stable support and buffer for the movable column, further ensuring the smoothness of the lifting process. This solves the problems of unstable lifting and shaking in traditional cutting devices, effectively preventing the cutting blades from shaking up and down or shifting left and right during the lifting process, and ensuring the flatness of the cutting surface and the integrity of the floor material.

[0053] Specifically, in this embodiment, each of the two side columns 6 opposite to each other is provided with a lifting groove 11. The lifting plate 13 is slidably installed in the lifting groove 11, and sliders 16 are provided on both sides of the lifting plate 13. The side column 6 is provided with a sliding groove 12 on both sides of the lifting groove 11, which is slidably engaged with the slider 16. The cooperation between the slider 16 and the sliding groove 12 helps to further improve the stability of the lifting movement of the lifting plate 13.

[0054] Furthermore, in some embodiments, the lifting drive unit includes a variable frequency motor 7 and a threaded rotating rod 15. The output end of the variable frequency motor 7 is fixedly connected to the threaded rotating rod 15 to drive the threaded rotating rod 15 to rotate. The top of the lifting plate 13 is machined with an internal threaded groove 14, and the other end of the threaded rotating rod 15 is threadedly engaged with the internal threaded groove 14. By adopting a helical transmission method of the threaded rotating rod and the internal threaded groove, combined with the sliding guide of the slider in the groove, the smooth lifting of the lifting plate is achieved. At the same time, the design of the limit spring and the sleeve plate provides stable support and buffer for the movable column, further ensuring the smoothness of the lifting process. With this lifting drive structure, when the spacing of the cutting blades is adjusted, the lifting plate 13 can also be locked in the height direction by the threaded engagement of the threaded rotating rod 15 and the threaded groove 14 to prevent shaking.

[0055] like Figure 4 , Figure 6 , Figure 8 As shown, in some embodiments, the outer plate 8 is machined with a moving groove 24, and the moving plate 26 can be slidably installed in the moving groove 24. To further improve the stability of the moving plate 26's up-and-down movement, limiting slide bars 27 are provided on both sides of the moving plate 26, and limiting grooves 25 are provided on both sides of the outer plate 8 located in the moving groove 24, which slide in cooperation with the limiting slide bars 27. In addition, when adjusting the spacing of the cutting blades, the cooperation between the limiting slide bars 27 and the limiting grooves 25 helps to further ensure the stability of the cutting blade adjustment. Furthermore, a variable frequency motor 35 is fixedly installed on each of the moving plates 26, and the cutting blade 9 is connected to the output end of the corresponding variable frequency motor 35. The variable frequency motor 35 can drive the cutting blade 9 to rotate, thereby cutting the epoxy self-leveling floor.

[0056] As a further preferred embodiment, such as Figure 2 , Figure 5As shown, a second slide groove 28 is machined on each side of the side column 6 on the base 1, and one end of the slide plate 30 can be slidably installed in the second slide groove 28; the spacing adjustment drive unit includes a second variable frequency motor 10 and a drive gear 34, wherein a gear groove 29 communicating with the second slide groove 28 is also machined on the outside of the base 1, and the drive gear 34 is rotatably installed in the gear groove 29 and connected to the output end of the second variable frequency motor 10. The two slide plates 30 on both sides of the outer plate 8 are provided with toothed mouths 31 on opposite sides, and the toothed mouths 31 are respectively meshed with a drive gear 34. The variable frequency motor 210 drives the drive gear 34 to rotate, thereby pushing the slide plate 30 to move the outer plate 8 and the cutting blade together through the meshing of the drive gear 34 and the toothed edge 31. This adjustment structure achieves precise electric adjustment of the cutting blade spacing. Compared with the existing manual or simple mechanical adjustment methods, it improves the accuracy and stability of the spacing adjustment, avoids errors caused by human factors, and thus ensures a smooth cutting edge, improving the overall quality of the floor. At the same time, it can also reduce the workload of construction personnel to frequently adjust and repeatedly check the cutting blade spacing, improving construction efficiency. Furthermore, the top of the slide groove 28 is provided with a support rod 33, and the bottom of the slide plate 30 is correspondingly machined with a support groove 32 that slides and engages with the support rod 33. The cooperation between the support rod 33 and the support groove 32 further improves the sliding stability of the slide plate 30.

[0057] To further reduce the amount of smoke and dust during the cutting process, such as Figure 1 As shown, the base 1 is further preferably provided with a processing box 36 on each side of the cutting blade 9. The processing box 36 is provided with an air-guiding unit and a filter unit. The air-guiding unit guides the smoke and dust generated during the cutting process to the filter unit for filtration.

[0058] Specifically, such as Figure 9 As shown, in this embodiment, the air extraction unit includes an exhaust fan 38. The inlet side of the exhaust fan 38 is connected to a dust inlet hood 39 via a dust inlet pipe 40. The dust inlet hood 39 is located on the side of the cutting blade 9. The output end of the exhaust fan 38 is connected to the filter unit via a dust exhaust pipe 41. The filter unit includes a filter box 37, which contains at least two filter screens. In this embodiment, two filter screens are provided: filter screen one 43 and filter screen two 44.

[0059] To facilitate movement and cutting of the flooring at different locations, this embodiment preferably includes casters 2 at each of the four corners of the base 1, and a push rod 3 on one side of the upper part of the base 1. Furthermore, support plates 4 are provided on both sides of the side pillars of the base 1, and a protective plate 5 is installed between the two support plates 4. For ease of operation, a control panel can be installed on the protective plate 5.

[0060] This invention also provides a method of using any of the above-mentioned floor cutting devices, including:

[0061] Step 1: Drive the slide plate 30 along the base 1 through the spacing adjustment drive unit, thereby driving the telescopic sliding connection unit to telescopically slide within the lifting plate 13, so that the outer plate 8 moves in the direction of approaching or moving away from the side column 6, thereby adjusting the spacing between the two cutting blades 9.

[0062] Specifically, the variable frequency motor 10 is started, which drives the drive gear 34 to rotate in the gear groove 29. The drive gear 34 meshes with the teeth 31 on the left and right slide plates 30, causing the slide plates 30 to slide in the slide groove 28. The movement of the slide plates 30 drives the movable column 18 to move in the movable groove 17 through the connecting plate 23. At the same time, the limiting slide bar 27 limits the movement in the limiting groove 25, thereby ensuring the stable movement of the cutting blade 9 and achieving precise control of the distance between the two cutting blades 9.

[0063] Step 2: Drive the lifting plate 13 to slide up and down along the side column 6 through the lifting drive unit. During the up and down sliding process of the lifting plate 13, drive the moving plate 26 to rise and fall along the inside of the outer plate 8 through the telescopic sliding connection unit, thereby realizing the adjustment of the height of the cutting blade 9.

[0064] Specifically, the variable frequency motor 7 is started, which drives the threaded rotating rod 15 to rotate in the internal thread groove 14. The rotation of the threaded rotating rod 15 causes the lifting plate 13 to move up and down in the lifting groove 11. At the same time, the slider 16 slides in the sliding groove 12 to ensure the smooth lifting of the lifting plate 13. The movement of the lifting plate 13 drives the moving plate 26 to rise and fall in the moving groove 24 in the outer plate 8 through the movable column 18 and the connecting plate 23, thereby adjusting the height of the cutting blade 9.

[0065] Step 3: After adjusting the cutting blade 9 to the appropriate height and spacing, start the variable frequency motor 7. The variable frequency motor 7 drives the threaded rotating rod 15 to rotate in the internal thread groove 14. The rotation of the threaded rotating rod 15 causes the lifting plate 13 to move up and down in the lifting groove 11. At the same time, the slider 16 slides in the sliding groove 12 to ensure the smooth lifting of the lifting plate 13. The movement of the lifting plate 13 drives the moving plate 26 to rise and fall in the moving groove 24 in the outer plate 8 through the movable column 18 and the connecting plate 23, thereby adjusting the height of the cutting blade 9.

[0066] More preferably, during the cutting process, the dust generated during cutting is guided to the filter unit by the induced draft unit for filtration and then discharged. Specifically, the induced draft fan 38 is used to discharge the dust generated during cutting into the filter box 37 through the dust inlet hood 39, the dust inlet pipe 40 and the dust outlet pipe 41. The dust is purified and filtered through multiple layers of filter screens in sequence, and finally discharged through the air outlet pipe 42. After cutting is completed, all motors are turned off and the cutting operation is stopped.

[0067] It should also be noted that the terms "installation," "setup," "equipped with," and "connection" used in this application should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts.
