Description

Technical Field

[0001] This application relates to the technical field of wooden door processing, and more particularly to a wooden door sanding device. Background Technology

[0002] Solid wood doors, as a mainstream high-end product in home decoration, not only possess natural wood grain textures and colors, but also offer diverse styles and exquisite carvings. Sanding is a crucial step in the production of wooden doors. Sanding is required between the unfinished door, each coat of primer, and the topcoat (generally at least two coats of primer). The quality of sanding directly affects the surface quality and overall appearance of the wooden door.

[0003] Typically, sanders can only perform single-sided sanding on boards (such as wooden doors and panels). In related technologies, some solutions use two sanders working in conjunction with a tilting conveyor mechanism to achieve continuous double-sided sanding of the boards; other solutions use only one sander with two sanding mechanisms arranged symmetrically inside to achieve a double-sided sanding effect.

[0004] However, all of these methods inevitably require an increase in the number of sanding units. As a key component of sanding operations, sanding units are characterized by high costs and complex subsequent maintenance, all of which directly impact the overall cost. Summary of the Invention

[0014] In one embodiment of this application, the plurality of auxiliary rollers, the plurality of suction heads, and the plurality of brush rollers are arranged in a corresponding staggered manner.

[0015] In one embodiment of this application, the second drive assembly is disposed within the mounting housing, and the second drive assembly includes a second drive motor, a plurality of sprockets and a chain, wherein the second drive motor is connected to one of the sprockets; the plurality of sprockets are respectively disposed at the ends of the corresponding auxiliary roller and the brush roller; and the chain is sleeved on the outside of two adjacent sprockets.

[0016] In one embodiment of this application, each of the conveyors is mounted on the housing via a lifting mechanism.

[0017] In one embodiment of this application, a support plate is provided on the outer side of the opening of the upper channel, and one end of the support plate is provided on the box body.

[0031] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0032] The following describes the wooden door sanding device according to an embodiment of this application with reference to the accompanying drawings.

[0033] like Figures 1-7 As shown, the wood door sanding device of this application embodiment may include a housing 10 and a sanding mechanism (not shown in the figure).

[0034] The housing 10 has two horizontally penetrating channels 11, which are arranged vertically. Each channel 11 contains a conveyor 20. The housing 10 also has a working space 12 located between and connected to the two channels 11. Support plates 80 are provided on the outer side of the openings of the upper channel 11. One end of each support plate 80 is attached to the housing 10 to support the sheet material 90 entering the upper channel 11, and the support plate 80 is located below the upper channel 11.

[0035] It should be noted that the conveyor 20 described in this embodiment adopts a belt conveyor method, and its components may include a frame 22, a conveyor belt 21, a drive system, etc., wherein the conveyor belt 21, the drive system, etc. are all mounted on the frame 22. The conveyor 20 is prior art and will not be described in detail here.

[0036] It is worth noting that the two conveyors 20 have opposite conveying directions. Within the same channel 11, the auxiliary roller 70, brush roller 41, and corresponding drive roller 32 rotate in the same direction, while the conveying direction of the conveyor belt 21 is opposite to that of the auxiliary roller 70. This design allows the conveyor belt 21 and the auxiliary roller 70 to work together, contacting and conveying the sheet 90 from both sides.

[0037] Furthermore, each conveyor 20 is mounted on the housing 10 via a lifting component 23. The lifting component 23 described in this embodiment can be a cylinder, a telescopic motor, etc. The frame 22 on the conveyor 20 is connected to the output end of the lifting component 23. The height of the conveyor 20 connected to it can be adjusted via the lifting component 23, thereby flexibly adjusting the height of the corresponding channel 11 according to the required thickness of the sheet material 90 to be sanded.

[0038] The sanding mechanism is located within the working space 12. The sanding mechanism may include a sanding component 30 and a dust removal component 40. The sanding component 30 may include a sanding belt 31 and multiple drive rollers 32. The upper and lower surfaces of the sanding belt 31 are both horizontally oriented, and both surfaces face the two channels 11 respectively. A mounting shell 13 is provided outside the housing 10. Multiple drive rollers 32 are respectively located on the inner and outer sides of the sanding belt 31, and each drive roller 32 is longitudinally oriented and connected to the first drive component 50 within the mounting shell 13.

[0039] Each drive roller 32 is movably disposed inside the housing 10. It should be noted that the first drive assembly 50 described in this embodiment has the function of controlling the synchronous rotation of multiple drive rollers 32. Specifically, the first drive assembly 50 may include a first drive motor 51, a synchronous belt 52 and multiple synchronous pulleys 53. The synchronous pulleys 53 correspond one-to-one with the drive rollers 32, and one end of the drive roller 32 movably passes through the corresponding mounting shell 13 and is connected to the corresponding synchronous pulley 53. The synchronous belt 52 is stretched on the multiple synchronous pulleys 53. The first drive motor 51 is disposed inside the mounting shell 13, and the output end of the first drive motor 51 is connected to one of the synchronous pulleys 53.

[0040] In this embodiment, six drive rollers 32 are provided. Four drive rollers 32 are arranged in a rectangular shape and are all located inside the sanding belt 31. The remaining two drive rollers 32 are respectively located between the two upper drive rollers 32 and the two lower drive rollers 32, and are all located outside the sanding belt 31. In addition, four corresponding synchronous pulleys 53 are located inside the synchronous belt 52, and the remaining two synchronous pulleys 53 are located outside the synchronous belt 52.

[0041] The first drive motor 51 can directly control the rotation of the synchronous pulley 53 connected to it. Under the action of the synchronous belt 52, multiple synchronous pulleys 53 rotate synchronously. Among them, the synchronous pulleys 53 located on the inner and outer sides of the synchronous belt 52 rotate in opposite directions, thereby causing multiple transmission rollers 32 to rotate accordingly, thereby driving the sand belt 31 to run smoothly.

[0042] It should be noted that both the first drive motor 51 and the second drive motor 61 described in this embodiment can be servo motors.

[0043] The dust removal assembly 40 may include multiple brush rollers 41 and multiple suction heads 42. Each brush roller 41 is longitudinally arranged within the working space 12 via a second drive assembly 60. Each brush roller 41 has cleaning components distributed on its outer side, which may be soft brushes, cleaning sponges, etc. The multiple suction heads 42 are arranged horizontally side by side. Each suction head 42 is mounted on the inner wall of the housing 10. Each suction head 42 has a first suction channel 421 and a second suction channel 422 that are symmetrically arranged vertically. The first suction channel 421 and the second suction channel 422 are respectively provided with multiple suction ports 423. The multiple first suction channels 421 are connected by a first pipe 43, and the multiple second suction channels 422 are connected by a second pipe 44. The first pipe 43 and the second pipe 44 respectively pass through the housing 10, and the first pipe 43 and the second pipe 44 are connected to the exhaust end of the vacuum cleaner 45 via a three-way valve 46.

[0044] In this embodiment, the three branches of the three-way valve 46 are respectively connected to the exhaust end of the vacuum cleaner 45, the first pipe 43 and the second pipe 44, and each of the first pipe 43 and the second pipe 44 can be provided with a valve for controlling opening and closing.

[0045] It should be noted that the vacuum cleaner 45 described in this embodiment is prior art. The vacuum cleaner 45 can generate suction on the first pipe 43 and / or the second pipe 44 through the three-way valve 46, thereby enabling multiple first suction channels 421 and / or second suction channels 422 to effectively absorb and remove impurities in the working space 12 through multiple suction ports 423.

[0046] It may also include multiple auxiliary rollers 70 arranged side by side in the same direction, wherein the auxiliary rollers 70, brush rollers 41 and drive rollers 32 are parallel to each other, and the outer surface of the auxiliary rollers 70 may be provided with a friction layer, wherein the friction layer may be made of rubber or the like, and each auxiliary roller 70 is connected to the second drive assembly 60.

[0047] Multiple auxiliary rollers 70, multiple suction heads 42, and multiple brush rollers 41 are arranged in a staggered manner. As one possible scenario, refer to... Figure 2 Both sides of the sanding belt 31 are equipped with brush rollers 41 and dust suction heads 42, which can clean and vacuum the board 90 before and after sanding respectively, thereby ensuring the sanding effect of the board 90.

[0048] It should be noted that the second drive assembly 60 described in this embodiment has the function of controlling multiple brush rollers 41 and multiple auxiliary rollers 70 to rotate synchronously and in the same direction. Specifically, the second drive assembly 60 may include a second drive motor 61, multiple sprockets 62 and a chain 63. The second drive motor 61 is connected to one of the sprockets 62, the multiple sprockets 62 are respectively disposed at the ends of the corresponding auxiliary rollers 70 and brush rollers 41, and the chain 63 is sleeved on the outside of two adjacent sprockets 62.

[0049] Understandably, the second drive motor 61 controls the sprocket 62 connected to it to rotate. Under the action of multiple chains 63 and sprockets 62, the multiple sprockets 62 rotate synchronously and in the same direction, thereby causing the multiple auxiliary rollers 70 and brush rollers 41 to rotate synchronously and in the same direction.

[0050] In the embodiments of this application, reference is made to Figure 3 Since auxiliary rollers 70 and brush rollers 41 are provided on both sides of the sanding assembly 30, the output end of the first drive motor 51 can pass through the corresponding chain 63 and connect with the corresponding transmission roller 32. This design ensures that the operation of the first drive assembly 50 and the second drive assembly 60 can proceed without interference, provided that they operate smoothly.

[0051] As one possible scenario, refer to Figure 7 At least two sets of sanding components 30 can be set up. The two sets of sanding components 30 work together to better sand the sheet 90.

[0052] Specifically, when double-sided sanding of sheet 90 is required, the operator first selects a channel 11 and inserts the first end of sheet 90 into one side opening of channel 11, allowing it to fall onto the conveyor belt 21 of the corresponding conveyor 20. Driven by the conveyor belt 21, sheet 90 enters channel 11 and finally exits from the other side opening of channel 11.

[0053] During the conveying process of sheet metal 90 within channel 11, it undergoes conveying operations by conveyor belt 21 and auxiliary roller 70, sanding operations by sanding belt 31, cleaning operations of the surface of sheet metal 90 (the side requiring sanding) by brush roller 41, and removal of impurities (including dust before sanding and debris after sanding) from the surface of sheet metal 90 by dust suction head 42. Conveyor belt 21, auxiliary roller 70, sanding belt 31, brush roller 41, and dust suction head 42 work together to complete the single-sided sanding operation of sheet metal 90.

[0054] On the same side of the housing 10, after the operator receives the sheet metal 90 after single-sided sanding, the sheet metal 90 can be immediately raised or lowered to pass through another channel 11. This allows the other channel 11 to sand the other side of the sheet metal 90 without needing to flip it over. This design enables the sanding assembly 30 to sand the sheet metal 90 in both the upper and lower channels 11, effectively reducing the investment and operating costs of the sanding assembly 30 while improving sanding efficiency, truly achieving the goal of cost reduction and efficiency improvement.

[0055] As one possibility, the two channels 11 in this embodiment can simultaneously accommodate the corresponding sheet metal 90. Specifically, the operator can place the two sheet metal 90 into the two channels 11 from both sides of the housing 10, thereby further improving the sanding efficiency of the sheet metal 90.

[0056] In summary, the wood door sanding device of this application embodiment has sanding components that can perform sanding operations on the boards in the upper and lower channels respectively, thereby achieving cost reduction and efficiency improvement.
