Description

Technical Field

[0001] This invention relates to the field of wood processing, and more specifically, to a polishing device for wood door processing and production. Background Technology

[0002] The process of polishing wooden doors mainly includes cleaning the surface, sanding, applying polishing agent, and final polishing. The polishing process of wooden doors can be divided into two types: manual polishing and mechanical polishing. Manual polishing refers to polishing the wood by hand with sandpaper, abrasive or polishing agent. This method is suitable for polishing small areas, complex or curved wooden products and can handle the details of the wood surface more precisely. Mechanical polishing uses mechanical equipment for polishing, mainly including planers, polishing machines and sanders. Mechanical polishing can improve work efficiency and is suitable for polishing large areas of flat wooden products.

[0003] Sanding is the most time-consuming and meticulous part of the polishing process. When sanding, the appropriate sanding paper and sanding tools should be selected according to the actual condition of the wooden door. Generally speaking, coarse sanding is performed first, using coarser sanding paper to remove unevenness and old paint layers from the surface of the wooden door. Then, medium sanding is performed, using medium-coarse sanding paper to further refine the surface. Finally, fine sanding is performed, using the finest sanding paper to finely sand the surface of the wooden door, making the surface of the wooden door smooth and delicate. During the sanding process, it should be done along the grain of the wooden door to avoid crossing the grain and causing scratches.

[0004] In existing technology, when rough grinding a wooden door, there is a difference in grinding speed between the edge and the center. The edge is usually thinner and more prone to wear. If the same force and speed are used as the center, it will lead to over-polishing, deformation or chipping. If the grinding tool is at the edge of the wooden door and the speed is suddenly reduced, the cutting force will increase instantly, resulting in greater compression and friction on the edge of the wooden door, which will lead to burrs or increased roughness. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a polishing equipment for wooden door processing and production.

[0006] To solve the above problems, the present invention adopts the following technical solution, which can realize the position of the grinding part in real time by measuring the height of the roller during the polishing process of the door panel, and adjust the rotation speed of the grinding part in time to avoid the cutting force from increasing suddenly due to a sudden decrease in the rotation speed of the grinding part.

[0007] A polishing device for wooden door processing and production includes a machine body and cylinders arranged in a rectangular array inside the upper part of the machine body. The telescopic ends of the cylinders are provided with an electric guide rail. Grinding parts are slidably connected inside the electric guide rail. A measuring component is provided on the upper side of the horizontal part of the machine body.

[0008] The measuring component includes a fixed frame disposed on the front and rear sides of the lower end of the electric guide rail. A movable groove is provided through the lower side of the fixed frame. A movable strip is slidably connected inside the movable groove. A connecting frame is fixedly connected to the lower side of the movable strip. Telescopic rods are fixedly connected to the left and right sides of the lower end of the connecting frame. Rollers are rotatably connected to the telescopic ends of the telescopic rods. Guide grooves are arranged in a rectangular array on the upper side of the machine body. After the rollers move, they are rolled and connected inside the guide grooves. A pressure sensor is disposed at the center of the lower side of the movable groove. After the movable strip moves downward, it presses and contacts the upper side of the pressure sensor.

[0009] Furthermore, the grinding part mainly consists of a drive motor and detachable grinding blades. The electric guide rail is I-shaped, and the front and rear fixed frames are located on the front and rear sides of the grinding part. The outer surface of the roller rolls over the upper side of the machine body, and the pressure sensor is electrically connected to an external power supply.

[0010] Furthermore, the inner and outer sides of the body are provided with a support assembly, which includes a first movable groove located at the center of the body.

[0011] Furthermore, an electric push rod is provided on the lower side of the interior of the first moving slot, and a connecting plate is fixedly connected to the telescopic end of the electric push rod. A support frame is fixedly connected to the upper side of the connecting plate. The connecting plate is slidably connected inside the first moving slot. A second moving slot is provided inside the body, and the support frame is slidably connected inside the second moving slot.

[0012] Furthermore, the shape of the first movable groove is adapted to the shape of the connecting plate, the shape of the support frame is rectangular, the shape of the support frame is adapted to the shape of the second movable groove, and the first movable groove and the second movable groove are connected.

[0013] Furthermore, the outer side of the machine body is provided with a cleaning component, which includes pressure springs arranged in a horizontal linear array and fixedly connected to the upper side of the movable bar.

[0014] Furthermore, the other end of the pressure spring is fixedly connected to the upper side inside the movable groove, a cleaning brush is fixedly connected to the lower side of the connecting frame, and collection frames are fixedly connected to both the front and rear sides of the machine body. The upper half of the second movable groove is connected to the collection frames.

[0015] Furthermore, the front and rear cleaning brushes are respectively located on the front and rear sides of the grinding workpiece, the distance between the cleaning brush and the grinding blade is 2 to 5 centimeters, and the support frame is always lower than the upper horizontal plane of the workpiece.

[0016] Furthermore, a rejection component is provided on the upper side of the horizontal part of the machine body, and the rejection component includes a fixed frame that is fixedly connected between the left and right vertical parts of the machine body.

[0017] Furthermore, the fixing frame is C-shaped, and the inner surface of the fixing frame is fixedly connected with a horizontal linear array of rejection strips. After the cleaning brush moves, it slides in staggered contact with the rejection strips.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) The present invention uses a roller to roll on the horizontal surface of the upper side of the machine body, and determines the position of the grinding part at this time based on the height of the roller during the rolling process. Since the position of the grinding part is measured in real time by the height of the roller during the polishing process of the door panel, and the rotation speed of the grinding part is quickly adjusted when the grinding part is detected to be at the edge of the door panel, the sudden reduction of the rotation speed of the grinding part is avoided, which would cause the cutting force to increase instantaneously. This reduces the squeezing and friction on the edge of the wooden door and reduces the possibility of burrs or increased roughness on the door panel.

[0020] (2) The present invention provides support for the outside of the door panel by setting a support frame when the grinding part moves to the edge of the door panel. When the grinding part is detected to start polishing the edge of the door panel, the support frame moves upward to surround the door panel and support the outside of the door panel, thus avoiding damage to the edge of the door panel caused by the sudden increase in cutting force after the grinding part suddenly reduces its speed. This ensures the polishing quality of the door panel.

[0021] (3) The present invention uses a cleaning brush to shield the splashed debris and also to clean the debris on the upper side of the door panel. During the polishing process of the grinding part on the door panel, the cleaning brush can shield the debris splashed by the grinding part during the polishing process to avoid the working environment around the machine being polluted. On the other hand, it can clean the debris that stays on the upper side of the door panel to prevent the debris that stays on the door panel surface from increasing the gap between the grinding part and the door panel, causing excessive wear on the door panel surface during the polishing process of the grinding part.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8 A polishing device for processing and producing wooden doors includes a body 1 and cylinders 11 arranged in a rectangular array inside the upper part of the body 1. The telescopic ends of multiple cylinders 11 are provided with an electric guide rail 12. Grinding parts 13 are slidably connected inside the electric guide rail 12. A measuring component 2 is provided on the upper side of the horizontal part of the body 1.

[0034] The measuring component 2 includes a fixed frame 21 set on the front and rear sides of the lower end of the electric guide rail 12. A movable groove 22 is opened through the lower side of the fixed frame 21. A movable bar 23 is slidably connected inside the movable groove 22. A connecting frame 231 is fixedly connected to the lower side of the movable bar 23. Telescopic rods 24 are fixedly connected to the left and right sides of the lower end of the connecting frame 231. Rollers 25 are rotatably connected to the telescopic ends of the telescopic rods 24. Guide grooves 26 are arranged in a rectangular array on the upper side of the machine body 1. After the rollers 25 move, they roll and connect inside the guide grooves 26. A pressure sensor 27 is set at the center of the lower side of the movable groove 22. After the movable bar 23 moves downward, it presses and contacts the upper side of the pressure sensor 27.

[0035] The grinding part 13 is mainly composed of a drive motor and a detachable grinding blade. The electric guide rail 12 is I-shaped. The front and rear fixed frames 21 are located on the front and rear sides of the grinding part 13. The outer surface of the roller 25 rolls and overlaps on the upper side of the machine body 1. The pressure sensor 27 is electrically connected to an external power supply.

[0036] By adopting the above technical solution, the door panel is placed above the horizontal part of the body 1. Then, the height of the electric guide rail 12 is adjusted by the cylinder 11. When the grinding part 13 contacts the surface of the door panel, the grinding part 13 is activated. Then, the grinding part 13, together with the electric guide rail 12, polishes the door panel. During this process, the movable bar 23 inside the fixed frame 21 moves downward inside the movable groove 22 due to the weight of the connecting frame 231. At this time, the telescopic rod 24 on the lower side of the connecting frame 231 rolls on the upper side of the horizontal part of the body 1 through the roller 25. As the electric guide rail 12 drives the grinding part 13 to move, the roller 25 also rolls on the upper side of the horizontal part of the body 1. When the roller 25 on either side enters the guide groove 26, the movable bar 23 moves downward inside the movable groove 22. When the movable bar 23 squeezes the pressure sensor 27 inside the movable groove 22, it indicates that the grinding part 13 has polished to the edge of the door panel. Then the pressure... Sensor 27 transmits information to the machine body 1. Then, the machine body 1 controls the grinding part 13 to reduce its rotation speed. After the electric guide rail 12 drives the grinding part 13 to move in the opposite direction, the roller 25 inside the guide groove 26 will roll back to the upper side of the horizontal part of the machine body 1. As the height of the roller 25 rises, the telescopic rod 24 drives the movable bar 23 to move upward inside the movable groove 22 through the connecting plate 283. When the movable bar 23 is disengaged from the pressure sensor 27, the rotation speed of the grinding part 13 gradually increases. Since the position of the grinding part 13 is measured in real time by the height of the roller 25 during the polishing process of the door panel, and the rotation speed of the grinding part 13 is quickly adjusted when it is detected that the grinding part 13 is at the edge of the door panel, the sudden reduction of the rotation speed of the grinding part 13 will prevent the cutting force from increasing instantaneously. This reduces the squeezing and friction on the edge of the wooden door and reduces the possibility of burrs or increased roughness on the door panel.

[0037] like Figures 5 to 8 As shown, the inner and outer sides of the body 1 are provided with a support component 28, and the support component 28 includes a first movable groove 281 opened at the center of the interior of the body 1.

[0038] An electric push rod 282 is provided on the lower side of the interior of the first moving slot 281. A connecting plate 283 is fixedly connected to the telescopic end of the electric push rod 282. A support frame 284 is fixedly connected to the upper side of the connecting plate 283. The connecting plate 283 is slidably connected inside the first moving slot 281. A second moving slot 285 is provided inside the body 1. The support frame 284 is slidably connected inside the second moving slot 285.

[0039] The shape of the first moving groove 281 is adapted to the shape of the connecting plate 283, the shape of the support frame 284 is rectangular, the shape of the support frame 284 is adapted to the shape of the second moving groove 285, and the first moving groove 281 and the second moving groove 285 are connected.

[0040] By adopting the above technical solution, as the movable bar 23 squeezes the pressure sensor 27 inside the movable groove 22, the pressure sensor 27 transmits information to the machine body 1, and the machine body 1 controls the cylinder 11 inside the first moving groove 281 to push the connecting plate 283 upward. As the connecting plate 283 slides inside the first moving groove 281, the support frame 284 fixed on the upper side of the connecting plate 283 begins to move upward under the push of the connecting plate 283 until it surrounds the outside of the door panel, but is always lower than the horizontal height of the upper side of the door panel. When the grinding part 13 polishes the edge of the door panel, the support frame 284 applies additional support force to the edge of the door panel. Since the support frame 284 moves upward to surround the door panel and support the outside of the door panel when it is detected that the grinding part 13 has started to polish the edge of the door panel, this avoids the instantaneous increase of cutting force after the grinding part 13 suddenly reduces its speed, which would cause damage to the edge of the door panel, thereby ensuring the polishing quality of the door panel.

[0041] like Figure 2 and Figures 5 to 8 As shown, the outer side of the body 1 is provided with a cleaning component 29, which includes pressure springs 291 arranged in a horizontal linear array and fixedly connected to the upper side of the movable bar 23.

[0042] The other end of the pressure spring 291 is fixedly connected to the upper side inside the movable groove 22. A cleaning brush 292 is fixedly connected to the lower side of the connecting frame 231. Collection frames 293 are fixedly connected to both the front and rear sides of the body 1. The upper part of the second movable groove 285 is connected to the collection frame 293.

[0043] The front and rear cleaning brushes 292 are located on the front and rear sides of the grinding workpiece 13, respectively. The distance between the cleaning brushes 292 and the grinding blade is 2 to 5 centimeters. The support frame 284 is always lower than the upper horizontal plane of the workpiece.

[0044] By adopting the above technical solution, when the electric guide rail 12 drives the grinding part 13 to start moving, the cleaning brush 292 on the lower side of the connecting frame 231 will move synchronously with the grinding part 13. The two cleaning brushes 292 are respectively located on the front and rear sides of the grinding part 13. Simultaneously, the pressure spring 291 inside the movable groove 22 always pushes the movable strip 23 downwards, ensuring that the cleaning brush 292 is always in contact with the surface of the door panel. When the grinding part 13 generates waste during the polishing process of the door panel, the cleaning brush 292 can shield the splashed waste and clean the waste remaining on the door panel surface. The cleaning brush 292 cleans the debris on the surface and collects the debris swept by the cleaning brush 292 through the collection box 293. During the polishing process of the grinding part 13 on the door panel, the cleaning brush 292 can block the debris splashed by the grinding part 13 during the polishing process to avoid contamination of the working environment around the machine body 1. On the other hand, it can clean the debris that stays on the upper part of the door panel to prevent the debris that stays on the door panel surface from increasing the gap between the grinding part 13 and the door panel, which would cause excessive wear on the door panel surface during the polishing process of the grinding part 13.

[0045] like Figure 3 and Figure 4 As shown, a rejection component 3 is provided on the upper side of the horizontal part of the machine body 1. The rejection component 3 includes a fixed frame 31 that is fixedly connected between the left and right vertical parts of the machine body 1.

[0046] The fixing frame 31 is C-shaped, and the inner surface of the fixing frame 31 is arranged in a horizontal linear array and fixedly connected with the removal strips 32. After the cleaning brush 292 moves, it slides in staggered contact with the removal strips 32.

[0047] By adopting the above technical solution, during the movement of the cleaning brush 292 driven by the electric guide rail 12, if the cleaning brush 292 comes into contact with the removal strip 32 inside the fixing frame 31, the cleaning brush 292 and the removal strip 32 will make staggered contact, so that the removal strip 32 can remove the waste debris that is stuck inside the cleaning brush 292 and collect it inside the collection frame 293. As the cleaning brush 292 continues to move, the cleaning brush 292 on the other side will also pass through the fixing frame 31 and the removal strip 32, and finally collect the waste debris again through the collection frame 293. Since the cleaning brush 292 can remove the waste debris generated during the polishing process of the grinding part 13 after cleaning the waste debris generated during the polishing process, the removal strip 32 can remove the waste debris that is stuck inside the cleaning brush 292, which prevents the waste debris inside the cleaning brush 292 from falling off when cleaning the waste debris on the upper side of the door panel in the future, thus ensuring the polishing quality of the door panel by the grinding part 13.

[0048] Working principle: The door panel is placed above the horizontal part of the machine body 1. Then, the height of the electric guide rail 12 is adjusted by the cylinder 11, and the door panel is polished in conjunction with the electric guide rail 12. During this process, the telescopic rod 24 on the lower side of the connecting frame 231 rolls on the upper side of the horizontal part of the machine body 1 via the roller 25. When the roller 25 on either side enters the guide groove 26, the movable bar 23 will move downward inside the movable groove 22. If the movable bar 23 squeezes the pressure sensor 27 inside the movable groove 22, it indicates that the grinding part 13 has polished to the edge of the door panel. The machine body 1 controls the grinding part 13 to reduce its speed. At the same time, the machine body 1 controls the cylinder 11 inside the first moving groove 281 to push the connecting plate 283 upward. The support frame 284 fixed on the upper side of the connecting plate 283 begins to move upward under the push of the connecting plate 283 until it surrounds the door panel. The cleaning brush 292 on the lower side of the connecting frame 231 moves synchronously with the grinding part 13 when the electric guide rail 12 drives the grinding part 13 to start moving. The two cleaning brushes 292 are located on the front and rear sides of the grinding part 13 respectively. Because the pressure spring 291 inside the movable groove 22 always pushes the movable strip 23 downward, the cleaning brush 292 is always in contact with the surface of the door panel. When the grinding part 13 produces waste during the polishing process of the door panel, the cleaning brush 292 can block the splashed waste and sweep the waste that stays on the surface of the door panel. The waste swept by the cleaning brush 292 is collected by the collection frame 293. If the cleaning brush 292 contacts the removal strip 32 inside the fixed frame 31, the removal strip 32 can remove the waste that stays in the cleaning brush 292 and collect it inside the collection frame 293.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
