Description

Technical Field

[0001] This invention relates to the field of wood recycling technology, specifically to a nail removal device for wood and its usage method. Background Technology

[0002] Wood recycling includes wood shredding and reprocessing as well as direct wood use. For direct wood use, nails need to be removed before the wood can be reused.

[0003] Among the existing technologies, patent application CN111805484A relates to the field of wood processing equipment, specifically a nail-picking device for wood processing. It includes a base, on which two uprights are fixed. A motor is fixed to the first upright, and a swing arm is rotatably connected to it. The motor and swing arm are connected in a transmission connection. A comb plate for picking up nails is provided on the second upright, which is also connected in a transmission connection to the swing arm. A third upright is fixed to the base, and a roller for conveying wood is rotatably connected to it. The roller is also connected in a transmission connection to the swing arm. A receiving mechanism for receiving nails is provided on the base. This nail-picking device for wood processing uses a motor to drive the roller to rotate, thereby automatically feeding the wood. The motor drives the comb plate through the swing arm to pull out nails from the wood, thus reducing the labor intensity of workers and improving work efficiency. The receiving mechanism driven by the swing arm automatically collects the nails pulled out of the wood by the comb plate, saving time and effort.

[0004] However, when removing nails from some recycled wood, the nail tips may be bent, which can cause serious damage to the wood if the nails are pulled out directly during the removal process. Furthermore, nails with bent tips are difficult to remove, which is not conducive to the recycling of wood. Therefore, a nail removal device for wood and its usage method are proposed. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a nail removal device for wood and its usage method, solving the problem of difficulty in removing nails with bent tips.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] In this invention, the nail removal device includes an upward-facing frame, on which a first mounting component and a second mounting component are mounted;

[0010] The second mounting component is equipped with a cutting mechanism, which includes a first slider and a cutting component mounted on the first slider. The cutting component is rotatably connected to the first slider via a rotating rod. The cutting component is driven by a drive motor, which provides driving force to the rotating rod. The cutting component includes a cutting disc.

[0011] A fixing mechanism is installed on the first mounting component, and a plate is installed on the fixing mechanism;

[0012] The plate has multiple nails distributed on it, each nail having a tip and a head.

[0013] The fixing mechanism includes a hollow placement frame, the plate is fixed to the placement frame by a negative pressure adsorption mechanism, and multiple nails are evenly distributed on the plate, each nail including a nail tip and a nail head.

[0014] During operation, the end of the board with the nail tip is located outside the placement frame, and the end of the board with the nail head is located inside the placement frame.

[0015] Furthermore, the first slider on the cutting mechanism moves horizontally via the first telescopic member, and the fixing mechanism moves vertically via the second telescopic member.

[0016] Furthermore, the first slider is slidably connected to the second mounting component via a groove.

[0017] Furthermore, a striking block is installed at the end of the cutting blade away from the first slider, and the distance between the edge of the striking block and the edge of the cutting blade is greater than the length of the plate.

[0018] Furthermore, the nail removal device also includes a nail pulling mechanism, which moves relative to the second mounting component via a third telescopic member. The nail pulling mechanism is provided with a mounting block, and the mounting block is provided with nail pulling components. The distance between two adjacent nail pulling components is greater than the diameter of the nail tip and less than the diameter of the nail head.

[0019] Furthermore, the nail-pulling assembly is provided with a second slider and a plurality of nail-pulling components. The plurality of nail-pulling components are slidably connected to the mounting block via the second slider. A threaded rod is rotatably connected to the mounting block. The second slider is threadedly sleeved on the threaded rod. The threaded rod can be driven by a first motor. The threaded rod is rotatably connected to the mounting block via a first connector.

[0020] Furthermore, the fixing mechanism has two plates, which are symmetrically arranged about the placement frame. The cutting mechanism has two sets, which cut the corresponding plates respectively. The nail pulling assembly has two sets, which correspond one-to-one with the plates. The mounting block is rotatably connected to a bidirectional threaded rod. The two second sliders are threaded onto the bidirectional threaded rod. The bidirectional threaded rod can be driven by a second motor. The bidirectional threaded rod is rotatably connected to the mounting block through a second connector.

[0021] A method of using a nail removal device for wood, comprising the nail removal device for wood, including the following two cases: nail removal of one board and simultaneous nail removal of two boards.

[0022] Furthermore, removing nails from a board specifically includes the following steps:

[0023] S1: Fixing the board: A board is placed on the placement frame near the end of the cutting mechanism of the fixing mechanism, and the negative pressure adsorption mechanism adsorbs and fixes the board.

[0024] S2: Cutting the bent part of the nail tip. The first telescopic component controls the movement of the cutting blade to adjust the relative horizontal position of the cutting mechanism and the fixed mechanism. The second telescopic component controls the movement of the fixed mechanism to adjust the vertical displacement between the cutting mechanism and the fixed mechanism. The drive motor is started to control the rotation of the cutting blade. During the rotation, the cutting blade moves towards the fixed mechanism, and the cutting blade cuts the bent part of the nail tip.

[0025] S3: Adjustment of the distance between the nail head and the board surface. The first telescopic component controls the hammering block to hammer the nail tip after the bent part is cut, increasing the distance between the nail head and the board surface.

[0026] S4: The nail-removing mechanism removes nails from the board. The second telescopic component controls the movement of the fixing mechanism to adjust the relative vertical height between the fixing mechanism and the nail-removing mechanism. The third telescopic component controls the movement of the nail-removing mechanism to adjust the horizontal displacement between the nail-removing mechanism and the fixing mechanism. After being adjusted to the appropriate position, the nail-removing component on the nail-removing mechanism is inserted into the gap between the nail head and the surface of the board. The threaded rod rotates, controlling the nail-removing component to move towards the nail head, thus realizing the nail removal operation of the board.

[0027] Furthermore, the removal of nails from the two boards specifically includes the following steps:

[0028] S1: Fixing the plates: The two plates are placed on the placement frame near the end of the fixing mechanism and the negative pressure adsorption mechanism adsorbs and fixes the plates.

[0029] S2: Cutting the bent portion of the nail tip. The first telescopic component controls the movement of the cutting blade to adjust the relative horizontal position of the cutting mechanism and the fixed mechanism. The second telescopic component controls the movement of the fixed mechanism to adjust the vertical displacement between the cutting mechanism and the fixed mechanism. The drive motor is started to control the rotation of the cutting blade. During the rotation, the cutting blade moves towards the fixed mechanism. The two cutting blades cut the bent portion of the nail tip on the corresponding plates, achieving synchronous cutting of the bent portion of the nail tip on the two plates.

[0030] S3: Adjustment of the distance between the nail head and the board surface. The first telescopic component controls the hammering block to hammer the nail tip after the bent part is cut, increasing the distance between the nail head and the board surface. The two hammering blocks simultaneously hammer the nails on the corresponding boards.

[0031] S4: The nail-pulling mechanism pulls nails from the board. The second telescopic component controls the movement of the fixing mechanism to adjust the relative vertical height between the fixing mechanism and the nail-pulling mechanism. The third telescopic component controls the movement of the nail-pulling mechanism to adjust the horizontal displacement between the nail-pulling mechanism and the fixing mechanism. After being adjusted to the appropriate position, the nail-pulling component on the nail-pulling mechanism is inserted into the gap between the nail head and the surface of the board. The bidirectional threaded rod rotates, controlling the nail-pulling components on the two sets of nail-pulling assemblies to move towards each other, realizing the synchronous nail-pulling operation of the two boards.

[0032] (III) Beneficial Effects

[0033] This invention provides a nail removal device for wood and a method for using it. Compared with the prior art, it has the following advantages:

[0034] By setting up a cutting mechanism and a fixing mechanism, the cutting blade cuts the nail tip during the rotation process, cutting off the bent part of the nail tip, which facilitates the subsequent nail removal operation of the board. This solves the problem in the prior art that the nail tip may be bent, which will cause serious damage to the board when the nail is pulled out directly during the nail removal process, and the nail with the bent tip is difficult to remove.

Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] This application provides a nail removal device for wood and its usage method, which solves the problem of nails with bent tips being difficult to remove, and achieves efficient recycling of wood panels.

[0057] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0058] like Figures 1-5 As shown, a nail removal device for wood includes an upward-facing frame 10, on which a first mounting member 101 and a second mounting member 102 are mounted.

[0059] The second mounting component 102 is equipped with a cutting mechanism 20. The cutting mechanism 20 includes a first slider 21 and a cutting component 22 mounted on the first slider 21. The cutting component 22 is rotatably connected to the first slider 21 through a rotating rod. The cutting component 22 is driven by a drive motor 23, which provides driving force to the rotating rod. The cutting component 22 includes a cutting disc 221.

[0060] A fixing mechanism 30 is installed on the first mounting component 101, and a plate 50 is installed on the fixing mechanism 30;

[0061] The plate 50 has a plurality of nails distributed on it, each nail having a tip 501 and a head 502, and the frame 10 is used to collect the removed nails.

[0062] The fixing mechanism 30 includes a hollow placement frame. The plate 50 is fixed to the placement frame by a negative pressure adsorption mechanism 301. Multiple nails are evenly distributed on the plate 50. Each nail includes a nail tip 501 and a nail head 502.

[0063] During operation, the end of the plate 50 with the nail tip 501 is located outside the placement frame, and the end of the plate 50 with the nail head 502 is located inside the placement frame.

[0064] The first slider 21 on the cutting mechanism 20 moves horizontally via the first telescopic member 211, and the first slider 21 is slidably connected to the second mounting member 102 via the slide groove 212. The fixing mechanism 30 moves vertically via the second telescopic member 302.

[0065] During operation, the second telescopic member 302 controls the fixing mechanism 30 to move vertically toward the cutting mechanism 20. The fixing mechanism 30 moves to the corresponding position above the cutting mechanism 20 and stops moving. Then, the first telescopic member 211 controls the cutting mechanism 20 to move toward the fixing mechanism 30. At the same time, the drive motor 23 is started, and the cutting piece 22 starts to rotate under the action of the drive motor 23. The second telescopic member 302 controls the fixing mechanism 30 to move, and the plate 50 on the fixing mechanism 30 moves toward the cutting blade 221. During the movement of the plate 50, the rotating cutting blade 221 cuts the nail tip 501, cutting off the bent part of the nail tip 501, which facilitates the subsequent nail removal operation of the plate 50. This solves the problem in the prior art that, due to the bending of the nail tip 501, directly pulling out the nail during the nail removal process will cause serious damage to the wooden board, and the nail with the bent tip is difficult to remove.

[0066] like Figures 1-9 , Figures 11-14 As shown, a striking block 222 is installed at the end of the cutting blade 221 away from the first slider 21, and the distance between the edge of the striking block 222 and the edge of the cutting blade 221 is greater than the length of the plate 50.

[0067] By setting a striking block 222, and ensuring that the distance between the edge of the striking block 222 and the edge of the cutting blade 221 is greater than the length of the plate 50, the striking block 222 will not interfere with the cutting of the nail tip 501 when the cutting blade 221 is cutting it. Furthermore, after the cutting blade 221 has finished cutting the nail tip 501, the first telescopic member 211 controls the striking block 222 to strike the remaining nail tip 501. Thus, after the nail tip 501 is partially cut and struck, the position between the nail tip 501 and the plate 50 changes from... Figure 12 Transform into Figure 14As shown in the figure, the distance between the nail head 502 and the board 50 increases, which facilitates the subsequent nail removal operation.

[0068] It should be noted that during the operation of the cutting mechanism 20 and the fixing mechanism 30, the distance can be controlled by a displacement sensor. Adjusting the control of the intelligent system through sensors and other devices is a conventional method and will not be elaborated here.

[0069] like Figure 1 , Figure 10 and Figure 16 As shown, the nail removal device also includes a nail pulling mechanism 40, which moves relative to the second mounting member 102 via a third telescopic member 401. The nail pulling mechanism 40 is provided with a mounting block 41, and the mounting block 41 is provided with a nail pulling assembly.

[0070] The nail-pulling assembly is provided with a second slider 42 and a plurality of nail-pulling components 421. The plurality of nail-pulling components 421 are slidably connected to the mounting block 41 via the second slider 42. A threaded rod 43 is rotatably connected to the mounting block 41. The second slider 42 is threadedly sleeved on the threaded rod 43. The threaded rod 43 can be driven by a first motor. The threaded rod 43 is rotatably connected to the mounting block 41 via a first connector.

[0071] In order to remove the nail by the nail puller 421, the distance between two adjacent nail pullers 421 is greater than the diameter of the nail tip 501 and less than the diameter of the nail head 502.

[0072] During operation, the second telescopic component 302 controls the movement of the placement frame until the distance between the nail head 502 and the plate 50 corresponds to the nail puller 421. Then, the third telescopic component 401 controls the nail puller 421 to be inserted between the nail head 502 and the plate 50. The first motor drives the threaded rod 43 to rotate, and the nail puller 421 moves in the opposite direction of the nail insertion into the plate 50, thereby pulling out the nail and completing the nail removal operation.

[0073] In another embodiment, such as Figure 15 and Figure 17 As shown, the fixing mechanism 30 has two plates 50, and the two plates 50 are symmetrically arranged about the placement frame. The cutting mechanism 20 has two sets, which are respectively used to cut the corresponding plates 50. The nail pulling assembly has two sets, and the nail pulling assembly corresponds to each plate 50.

[0074] A bidirectional threaded rod 44 is rotatably connected to the mounting block 41. Both second sliders 42 are threaded onto the bidirectional threaded rod 44. The bidirectional threaded rod 44 can be driven by a second motor. The bidirectional threaded rod 44 is rotatably connected to the mounting block 41 through a second connector.

[0075] During operation, the second telescopic component 302 controls the movement of the placement frame until the distance between the nail head 502 and the plate 50 corresponds to the nail puller 421. Then, the third telescopic component 401 controls the nail puller 421 to insert between the nail head 502 and the plate 50. The second motor drives the bidirectional threaded rod 44 to rotate, and the bidirectional threaded rod 44 controls the two second sliders 42 to move towards each other. Thus, the nail puller 421 moves in the opposite direction of the nail insertion into the plate 50, realizing the nail removal operation and completing the nail removal operation. The nail removal operation of two plates 50 is completed at one time, improving the nail removal efficiency of the plates 50.

[0076] It should be noted that when the bidirectional threaded rod 44 is set to simultaneously remove nails from the two plates 50, the second slider 42 corresponds one-to-one with the position of the plate 50, thereby achieving the synchronous nail removal operation of the two plates 50.

[0077] In practical applications, in order to maintain the stability of the fixing mechanism 30, the placement frame can be slidably connected to the second mounting component 102.

[0078] A method of using a nail removal device for wood includes the following two scenarios: nail removal from one board 50 and simultaneous nail removal from two boards 50.

[0079] like Figure 1 , Figure 14 and Figure 16 As shown, removing nails from a 50mm board specifically includes the following steps:

[0080] S1: Fixing of plate 50: A plate 50 is placed on the placement frame of the fixing mechanism 30 near the end of the cutting mechanism 20, and the negative pressure adsorption mechanism 301 adsorbs and fixes the plate 50.

[0081] S2: Cutting the bent portion of the nail tip 501. The first telescopic member 211 controls the movement of the cutting blade 221 to adjust the relative horizontal position of the cutting mechanism 20 and the fixing mechanism 30. The second telescopic member 302 controls the movement of the fixing mechanism 30 to adjust the vertical displacement between the cutting mechanism 20 and the fixing mechanism 30. The drive motor 23 is started to control the rotation of the cutting blade 221. During the rotation, the cutting blade 221 moves towards the fixing mechanism 30, and the cutting blade 221 cuts the bent portion of the nail tip 501.

[0082] S3: Adjustment of the distance between the nail head 502 and the surface of the plate 50. The first telescopic component 211 controls the hammering block 222 to hammer the nail tip 501 after the bent part is cut, thereby increasing the distance between the nail head 502 and the surface of the plate 50.

[0083] S4: The nail-pulling mechanism 40 pulls nails from the board 50. The second telescopic member 302 controls the movement of the fixing mechanism 30 to adjust the relative vertical height between the fixing mechanism 30 and the nail-pulling mechanism 40. The third telescopic member 401 controls the movement of the nail-pulling mechanism 40 to adjust the horizontal displacement between the nail-pulling mechanism 40 and the fixing mechanism 30. After adjusting to the appropriate position, the nail-pulling part 421 on the nail-pulling mechanism 40 is inserted into the gap between the nail head 502 and the surface of the board 50. The threaded rod 43 rotates to control the nail-pulling part 421 to move towards the nail head 502, thereby realizing the nail-pulling operation of the board 50.

[0084] like Figure 15 and Figure 17 As shown, removing nails from two 50mm boards specifically includes the following steps:

[0085] S1: Fixing of the plate 50: The two plates 50 are placed on the placement frame of the fixing mechanism 30 near the end of the cutting mechanism 20, and the negative pressure adsorption mechanism 301 adsorbs and fixes the plates 50.

[0086] S2: Cutting of the bent portion of the nail tip 501. The first telescopic component 211 controls the movement of the cutting blade 221 to adjust the relative horizontal position of the cutting mechanism 20 and the fixing mechanism 30. The second telescopic component 302 controls the movement of the fixing mechanism 30 to adjust the vertical displacement between the cutting mechanism 20 and the fixing mechanism 30. The drive motor 23 is started to control the rotation of the cutting blade 221. During the rotation, the cutting blade 221 moves towards the fixing mechanism 30. The two cutting blades 221 cut the bent portion of the nail tip 501 on the corresponding plate 50, realizing synchronous cutting of the bent portion of the nail tip 501 on the two plates 50.

[0087] S3: Adjustment of the distance between the nail head 502 and the surface of the plate 50. The first telescopic component 211 controls the hammering block 222 to hammer the nail tip 501 after the bent part is cut, increasing the distance between the nail head 502 and the surface of the plate 50. The two hammering blocks 222 simultaneously hammer the nails on the corresponding plate 50.

[0088] S4: The nail-pulling mechanism 40 pulls nails from the board 50. The second telescopic component 302 controls the movement of the fixing mechanism 30 to adjust the relative vertical height between the fixing mechanism 30 and the nail-pulling mechanism 40. The third telescopic component 401 controls the movement of the nail-pulling mechanism 40 to adjust the horizontal displacement between the nail-pulling mechanism 40 and the fixing mechanism 30. After adjusting to the appropriate position, the nail-pulling component 421 on the nail-pulling mechanism 40 is inserted into the gap between the nail head 502 and the surface of the board 50. The bidirectional threaded rod 44 rotates to control the nail-pulling components 421 on the two sets of nail-pulling assemblies to move towards each other, so as to realize the synchronous nail-pulling operation of the two boards 50.

[0089] In summary, compared with existing technologies, it has the following beneficial effects:

[0090] 1. By setting up a cutting mechanism 20 and a fixing mechanism 30, the cutting blade 221 cuts the nail tip 501 during the rotation process, cutting off the bent part of the nail tip 501, thereby facilitating the subsequent nail removal operation of the board 50. This solves the problem in the prior art that, due to the bending of the nail tip 501, directly pulling out the nail during the nail removal process would cause serious damage to the board, and that nails with bent tips are difficult to remove.

[0091] 2. By setting the striking block 222, after the cutting blade 221 has partially cut the nail tip 501, the first telescopic member 211 controls the striking block 222 to strike the remaining nail tip 501 after cutting. As a result, after the nail tip 501 is partially cut and struck, the distance between the nail head 502 and the plate 50 increases, which facilitates the subsequent nail removal operation.

[0092] 3. By controlling the two second sliders 42 to move towards each other through the bidirectional threaded rod 44, the nail puller 421 moves in the opposite direction of the nail insertion into the plate 50, thereby pulling out the nail and completing the nail removal operation. The nail removal operation of two plates 50 is completed at one time, improving the nail removal efficiency of the plate 50.
