[0001] The utility model relates to the technical field of chamfering machines, in particular to a PVC plastic mosaic chamfering machine. Background Technique

[0002] A chamfering machine is a small precision machine tool specialized for chamfering and deburring products processed by methods such as milling and planing in mold manufacturing, hardware machinery, machine tool manufacturing, hydraulic parts, valve manufacturing, and textile machinery. Currently, during the processing and production of PVC plastics, burrs will be generated on the edges, and a mosaic chamfering machine is required to polish and chamfer the workpieces.

[0003] When the existing mosaic chamfering machine is in use, generally, the workpieces are conveyed to the chamfering head through a conveyor belt for chamfering treatment. However, since the chamfering head is generally fixed to the machine frame by bolts, the position cannot be adjusted according to the width of the workpiece, resulting in poor use effect. Moreover, a large amount of debris will be generated during the chamfering process, and these debris will directly scatter into the surrounding environment, causing pollution to the surrounding environment. For this reason, we propose a PVC plastic mosaic chamfering machine. Content of the Utility Model

Detailed Embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Refer to Figures 1 - 4, a PVC plastic mosaic chamfering machine, including a base 1. A U-shaped frame 25 is installed on the top of the base 1. Guide grooves 8 are symmetrically opened at the top of the U-shaped frame 25. First strip-shaped connecting plates 5 are arranged inside the guide grooves 8. Both ends of each first strip-shaped connecting plate 5 extend out of the guide grooves 8. And fixed plates 4 are vertically installed at both ends of the top of each guide groove 8. A lead screw 7 is rotatably connected between each pair of fixed plates 4. And the two lead screws 7 have opposite helix directions. Each lead screw 7 passes through the corresponding first strip-shaped connecting plate 5 and is threadedly connected to the first strip-shaped connecting plate 5. A double-shaft motor 6 is installed on the top of the U-shaped frame 25. One end of each lead screw 7 is connected to the output shaft of the double-shaft motor 6. During actual use, the double-shaft motor 6 can drive the two lead screws 7 to rotate synchronously. Under the action of the lead screws 7, the two first strip-shaped connecting plates 5 can move relatively synchronously.

[0030] It should be noted that both sides of each first strip-shaped connecting plate 5 are slidably connected to the guide rails fixed on both sides of the guide groove 8 through sliders. This can guide the first strip-shaped connecting plate 5 and make the first strip-shaped connecting plate 5 keep stable.

[0031] As Figure 1 and Figure 2 shown, a second strip-shaped connecting plate 23 is installed at the bottom of each first strip-shaped connecting plate 5. Mounting seats 20 are installed on the adjacent surfaces of the two second strip-shaped connecting plates 23. A cutter head 16 is rotatably connected to the bottom of each mounting seat 20. A first driving motor 9 is connected to the top of each cutter head 16. The first driving motor 9 is fixed on the corresponding mounting seat 20. And a limiting plate 19 is installed at the other end of each second strip-shaped connecting plate 23. During actual use, the first driving motor 9 can drive the cutter head 16 to rotate to polish and chamfer the material to be chamfered. And during use, under the action of the double-shaft motor 6, the relative positions of the two cutter heads 16 can be adjusted. At the same time, the positions between the two limiting plates 19 can be adjusted, and materials with different widths can be limited and chamfered.

[0032] It should be noted that the bottom of the limiting plate 19 is higher than the upper part of the conveyor belt 3. And one end of each limiting plate 19 is inclined outward. In this way, the limiting plate 19 will not collide with the conveyor belt 3 during use.

[0033] It should be noted that the open end of the dust-proof cover 24 is flush with the side of the limiting plate 19 close to the conveyor belt 3. And the side of the cutter head 16 close to the conveyor belt 3 extends outside the dust-proof cover 24. In this way, during use, after the limiting plate 19 positions the material, the cutter head 16 can chamfer the edge of the material. And the dust-proof cover 24 will not interfere with the cutter head 16.

[0034] As Figure 1 and Figure 3As shown, strip-shaped fixing seats 32 are symmetrically installed on the top of the base 1. A number of support shafts 33 are rotatably connected between the two strip-shaped fixing seats 32. The support shafts 33 are connected by a conveyor belt 3, and one of the support shafts 33 at one end is connected to the second drive motor 34. The second drive motor 34 is fixed on the base 1. During actual use, the conveyor belt 3 can be driven by the second drive motor 34 to move and convey materials.

[0035] As Figure 1 and Figure 2 As shown, dust-proof covers 24 are installed on both sides inside the U-shaped frame 25. Strip-shaped mounting plates 18 are installed on both sides of the dust-proof covers 24 close to the opening, and the tops of the strip-shaped mounting plates 18 are fixed to the bottom of the second strip-shaped connecting plate 23. During actual use, the debris generated at the chamfering part will be blocked by the dust-proof cover 24 under the action of inertia, which can prevent the debris generated by chamfering from scattering into the surrounding environment, and the remaining debris will remain on the conveyor belt 3.

[0036] As Figure 1 and Figure 4 As shown, second through grooves 17 are symmetrically opened on both sides of the top of the base 1. Each second through groove 17 is located inside the corresponding dust-proof cover 24. A first through groove 2 is opened on the top of the base 1 and at the bottom of the conveyor belt 3. Both sides of the first through groove 2 are connected to the second through groove 17. The debris blocked by the dust-proof cover 24 will be discharged from the second through groove 17 under the action of gravity, and the debris falling on the conveyor belt 3 will be discharged from the first through groove 2 under the action of gravity.

[0037] As Figure 1 and Figure 3 As shown, a number of pairs of legs 26 are installed on both sides of the bottom of the base 1. A storage plate 28 is provided at the bottom of the base 1. The storage plate 28 is located below the U-shaped frame 25, and both sides of the storage plate 28 are fixed to the legs 26. A collection box 27 is provided on the top of the storage plate 28. One side of the top of the collection box 27 is installed with a guide plate 31 through a bracket. The guide plate 31 is located below the first through groove 2. During actual use, the debris discharged from the second through groove 17 will directly fall into the collection box 27 for collection. The debris falling on the conveyor belt 3 will fall on the guide plate 31 and fall into the collection box 27 along the guide plate 31.

[0038] It should be noted that the guide plate 31 is inclined, and strip-shaped baffles 30 are installed on both sides of the top of the guide plate 31. In this way, during actual use, the debris falling on the guide plate 31 from the conveyor belt 3 will fall into the collection box 27 along the guide plate 31 under the action of gravity and will not remain on the guide plate 31. And under the action of the strip-shaped baffles 30, the debris can be prevented from scattering from both sides of the guide plate 31.

[0039] It should be noted that as Figure 1As shown in the figure, vertical plates 21 are symmetrically installed at the top of the base 1. A partition plate 22 is installed between the two vertical plates 21. There is a gap between the bottom of the partition plate 22 and the conveyor belt 3, and this gap is greater than the thickness of a single material to be chamfered and less than the thickness of two stacked materials to be chamfered. During actual use, the staff can stack the materials to be chamfered and place them on one side of the partition plate 22. Under the action of the conveyor belt 3, the lowermost material can be driven to move, so that the lowermost material passes through the partition plate 22 and moves to the tool head 16 for chamfering. The remaining materials will fall on the conveyor belt 3 under the action of gravity. In this way, under the action of the conveyor belt 3, the lowermost material is conveyed to the tool head 16 for chamfering again, and the feeding is convenient.

[0040] Specifically, when the present utility model is in use, the staff controls the double-shaft motor 6 to work. The double-shaft motor 6 drives the two lead screws 7 to rotate synchronously, so that the two first strip-shaped connecting plates 5 move relatively synchronously, and the tool head 16 and the limiting plate 19 move synchronously following the first strip-shaped connecting plate 5. Thus, the tool head 16 and the limiting plate 19 can be adjusted to the preset position according to the width of the material to be chamfered. After that, the staff stacks the materials on one side of the partition plate 22, and then drives the conveyor belt 3 to move through the second driving motor 34. Under the action of the conveyor belt 3, the materials can be sequentially conveyed to the tool head 16 for chamfering. Some of the chips generated by chamfering will be blocked by the dust-proof cover 24, and this part of the chips will be discharged into the collection box 27 below along the second through groove 17 for collection. The remaining chips will remain on the conveyor belt 3. When the part of the conveyor belt 3 with chips moves to the lower part, under the action of gravity, the chips will fall onto the guiding plate 31 and fall into the collection box 27 along the guiding plate 31 for collection.

[0041] Furthermore, the dust-proof cover 24 is made of a flexible and telescopic material. During use, the dust-proof cover 24 can be telescopically adjusted according to the position of the tool head 16, so that the dust-proof cover 24 can maintain a normal dust-proof effect.

[0042] Furthermore, as Figure 3 shown, scraping plates 10 are installed on the adjacent surfaces of the two strip-shaped baffles 30. One end of the scraping plate 10 is in contact with the bottom of the conveyor belt 3. There is a gap between the bottom of the scraping plate 10 and the guiding plate 31. The chips adhered to the surface of the conveyor belt 3 can be scraped off by the scraping plate 10. The scraped chips will fall onto the guiding plate 31 under the action of gravity and fall into the collection box 27 along the guiding plate 31 for collection.

[0043] Furthermore, as Figure 2As shown in the figure, a sliding rod 11 is vertically installed inside the U-shaped frame 25. A sliding sleeve 29 is slidably sleeved at the bottom of the sliding rod 11. The bottom of the sliding sleeve 29 is fixed on the U-shaped seat 14. And a pressing wheel 15 is rotatably connected inside the U-shaped seat 14. The pressing wheel 15 is located above the conveyor belt 3. Connecting rings 13 are installed on the side of the sliding rod 11 and the top side of the sliding sleeve 29. A spring 12 is sleeved on the side of the sliding rod 11. The spring 12 is located between the two connecting rings 13. And the two ends of the spring 12 are respectively fixed on the corresponding connecting rings 13. During actual use, the elastic force of the spring 12 can make the bottom of the pressing wheel 15 contact the material on the conveyor belt 3 to limit the material and prevent the material from shifting in position.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
