Description

Technical Field

[0001] This utility model belongs to the field of wood flooring manufacturing technology, and more specifically, it relates to a wood flooring polishing and deburring device. Background Technology

[0002] During the production of wood flooring, it needs to be cut according to the specified dimensions. After cutting, the edges need to be sanded to remove burrs, and the end face (usually the top end face) also needs to be sanded. Chinese utility model patent application number 202323272534.3 discloses a multi-layer solid wood flooring polishing and deburring device. This device "rotates the board using a rotating mechanism and polishes the other two sides of the board using another set of edge-trimming mechanisms, enabling all-around polishing and edge-trimming operations." However, it has the following shortcomings: First, this rotating operation causes relative displacement between the conveyor belt and the wood flooring, resulting in wear on both, which is detrimental to product quality assurance and equipment lifespan. Second, when the rotating mechanism rotates the wood flooring, the conveyor belt cannot transport the wood, preventing polishing and grinding, thus reducing work efficiency. Third, using a conveyor belt allows fine particles generated during deburring and polishing to easily enter the belt, affecting the stability of subsequent wood flooring transport, and its small internal space makes cleaning inconvenient. Fourth, the lack of a calibration mechanism to support the wood flooring makes it prone to tilting due to uneven force when using grinding rollers to polish the edges, affecting the quality of deburring. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wood floor polishing and deburring device, which realizes the horizontal and vertical transportation of wood flooring by setting up a first roller conveyor, a second roller conveyor, a third roller conveyor and a fourth roller conveyor, and realizes the centering and calibration of the position of the wood flooring by a calibration mechanism.

[0004] A wood floor polishing and deburring device includes a first conveying mechanism, a second conveying mechanism, and a controller. The first conveying mechanism includes a first roller conveyor and a second roller conveyor, and the second conveying mechanism includes a third roller conveyor and a fourth roller conveyor. The first and second roller conveyors are vertically aligned and convey the wood flooring in the same direction. The third and fourth roller conveyors are also vertically aligned and convey the wood flooring in the same direction. The direction in which the first and second conveying mechanisms convey the wood flooring is horizontal. The conveyor is arranged in a cross shape. The first or second conveyor includes a polishing mechanism, and the first and second conveyor each include a grinding mechanism. The polishing mechanism drives the polishing roller to rotate. The polishing roller's axis is parallel to the wood flooring. The grinding mechanism drives the grinding roller to rotate. The grinding roller is located on both sides of the wood flooring conveying direction, and its axis is perpendicular to the wood flooring. The first, second, third, and fourth roller conveyors are all electrically driven and controlled by a controller, which is connected to an external power source.

[0005] Preferably, the first roller conveyor includes a first support base and a first roller, the second roller conveyor includes a second support base and a second roller, and the third roller conveyor includes a third support base and a third roller.

[0006] Preferably, the No. 4 roller conveyor includes a No. 4 support base and a No. 4 roller. The No. 4 support base is rotatably connected to multiple No. 4 rollers. All No. 4 rollers are in the same horizontal plane and are parallel to each other. The polishing mechanism is located inside the No. 1 conveying mechanism.

[0007] Preferably, the polishing mechanism includes a first speed-regulating motor and a polishing roller. The second support base is fixed with the first speed-regulating motor and rotatably connected to the polishing roller. The first speed-regulating motor and the polishing roller are coaxially connected to achieve synchronous rotation. The polishing roller is parallel to the first roller and the second roller. The first speed-regulating motor is electrically connected to the controller.

[0008] Preferably, the sanding mechanism includes a second distance adjustment mechanism, a second speed-regulating motor, and a sanding roller. The first support base and the third support base are respectively equipped with the second distance adjustment mechanism. The second distance adjustment mechanism is used to adjust the distance between the second speed-regulating motor and the wooden floor. The rotating shaft of the second speed-regulating motor is coaxially connected with the sanding roller to achieve synchronous rotation. The circumferential part of the sanding roller contacts the two sides of the wooden floor in the direction of movement. Each of the second speed-regulating motors is electrically connected to the controller.

[0009] Preferably, the second adjustment mechanism includes a second servo motor, a second bidirectional lead screw, a guide groove, a second main sliding seat, a second auxiliary sliding seat, and a second compression spring. The first and third support seats are respectively fixed with the second servo motor and the guide groove. The first and third support seats are respectively rotatably connected to the second bidirectional lead screw. The external threads of the two axial parts of the second bidirectional lead screw have opposite directions of rotation. The extension direction of the second bidirectional lead screw is the same as that of the adjacent guide groove. The guide groove slides along its extension direction with two second main sliding seats and two second auxiliary sliding seats. The two second main sliding seats within the guide groove... The moving seat and the second auxiliary sliding seat are located on both sides of the wooden floor moving direction. The two second main sliding seats in the same guide groove are axially threaded to the two parts of the second bidirectional lead screw. The second auxiliary sliding seat is interlocked with the second bidirectional lead screw. The second auxiliary sliding seat is closer to the edges of the wooden floor moving direction than the second main sliding seat. The second auxiliary sliding seat and the second main sliding seat are fixed together by a second compression spring. Under the elastic repulsive force of the second compression spring, the second auxiliary sliding seat tends to move closer to the edges of the wooden floor moving direction. The second servo motor is electrically connected to the controller.

[0010] Preferably, the second and third support bases are each equipped with a calibration mechanism. The calibration mechanism includes a third servo motor, a third bidirectional lead screw, a guide rod, a third main sliding seat, a third auxiliary sliding seat, a third compression spring, and a contact roller. The second and third support bases are each fixed with a third servo motor and rotatably connected to a third bidirectional lead screw. The third servo motor is electrically connected to a controller. The shaft of the third servo motor and the third bidirectional lead screw are coaxially connected to achieve synchronous rotation. The external threads on the two axial portions of the third bidirectional lead screw have opposite directions of rotation. The second and third support bases are each fixed with multiple guide rods, and the two axial portions of the same guide rod are axially slidably connected to a third guide rod. The main sliding seat and the third auxiliary sliding seat, two third main sliding seats and two third auxiliary sliding seats on the two axial portions of the same guide rod are located on both sides of the wood flooring's movement direction. A third compression spring is fixed between the third main sliding seat and the third auxiliary sliding seat. Under the elastic repulsive force of the third compression spring, the third auxiliary sliding seat tends to move closer to the edges on both sides of the wood flooring's movement direction. The two axial portions of the third bidirectional lead screw are respectively threaded through to the third main sliding seat. The third auxiliary sliding seat is rotatably connected to a contact roller. The contact roller is set perpendicular to the wood flooring and located on both sides of the third bidirectional lead screw's axial direction. The contact rollers on the same third auxiliary sliding seat are arranged correspondingly to each other in the wood flooring's movement direction.

[0011] Preferably, the outer circumference of the polishing roller is provided with a coaxial and annular flared groove, the minimum width of which is greater than the thickness of the wood flooring and corresponds horizontally to the edge of the wood flooring.

[0012] Preferably, the wood floor polishing and deburring device further includes a lifting mechanism, which includes a base, an upper electric push rod, and a lower electric push rod. The base is fixed to a first support seat and a third support seat. Multiple upper electric push rods are fixed to the upper part of the base, and multiple lower electric push rods are fixed to the bottom. The bottom end of each upper electric push rod is fixed to a second support seat, and the top end of each lower electric push rod is fixed to a fourth support seat. The fourth support seat is vertically and horizontally inserted into the first support seat. The fourth roller and the first roller are staggered. The first roller corresponds vertically to the second roller, and the third roller corresponds vertically to the fourth roller.

[0013] Preferably, the fourth support base is further rotatably connected at equal intervals to multiple fifth rollers. The spacing between the fifth rollers is smaller than that between the fourth rollers. The fifth rollers are in the same plane and parallel to the fourth rollers. The top edge of the outer circumferential wall of the fifth roller is coplanar with the top edge of the outer circumferential wall of the fourth roller. Furthermore, because the spacing between the fifth rollers is smaller than that between the fourth rollers, the fourth rollers can more smoothly transport the wooden floor to the left when lifting and conveying it, while the larger spacing between the fourth rollers meets the needs of the calibration and sanding mechanisms.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Using roller conveyors No. 1 and No. 2, the upper and lower ends of the wooden floorboards can be clamped for forward transport. When the wooden floorboards move to roller conveyor No. 3, roller conveyors No. 3 and No. 4 clamp the upper and lower ends of the wooden floorboards for leftward transport. Compared with conveyor belts, this method provides more open space and is easier to clean. Compared with existing technologies, it eliminates the need to rotate the wooden floorboards, which is beneficial for ensuring product quality and extending the service life of the device. Furthermore, the No. 1 and No. 2 conveyor mechanisms do not interfere with each other, meaning that different wooden floorboards can move forward and to the left simultaneously without reducing work efficiency.

[0015] 2. By controlling the forward and reverse rotation of servo motor No. 3, and utilizing the threaded connection between the No. 3 bidirectional lead screw and the No. 3 main sliding seat, the contact rollers on both sides of the wood flooring's movement direction can be brought closer and further apart, thereby adjusting the position of the wood flooring and ensuring that the movement direction of the wood flooring is parallel to the edge to be sanded. The No. 3 compression spring allows the distance between the No. 3 auxiliary sliding seat and the No. 3 main sliding seat to decrease and increase back to its original position. This ensures that when the contact rollers come into contact with the wood flooring, they will not cause damage to the device or the wood flooring due to the continued approach of the No. 3 main sliding seat, thus providing a safety margin and facilitating timely manual control of servo motor No. 3 to stop. At the same time, the pressure applied by the contact rollers on both sides of the wood flooring's movement direction tends to be uniform under the elastic repulsive force of the No. 3 compression spring, thus achieving centering and calibration of the wood flooring's position and preventing the wood flooring from tilting.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] As attached Figure 1 -Appendix Figure 4As shown, a wood floor polishing and deburring device includes a first conveying mechanism 1, a second conveying mechanism 2, and a controller. The first conveying mechanism 1 includes a first roller conveyor 4 and a second roller conveyor 5. The second conveying mechanism 2 includes a third roller conveyor 6 and a fourth roller conveyor 7. The first roller conveyor 4 and the second roller conveyor 5 are vertically aligned and convey the wood flooring in the same direction. The third roller conveyor 6 and the fourth roller conveyor 7 are also vertically aligned and convey the wood flooring in the same direction. The direction in which the first conveying mechanism 1 conveys the wood flooring and the direction in which the second conveying mechanism 2 conveys the wood flooring form a horizontal cross shape. Mechanism 1 or conveyor 2 includes a polishing mechanism. Both conveyor 1 and conveyor 2 include a grinding mechanism. The polishing mechanism drives the polishing roller 10 to rotate. The polishing roller 10 is axially parallel to the wood flooring. The grinding mechanism drives the grinding roller 11 to rotate. The grinding roller 11 is located on both sides of the wood flooring conveying direction and its axial direction is perpendicular to the wood flooring. The roller conveyor 4, roller conveyor 5, roller conveyor 6, and roller conveyor 7 are electrically driven and controlled by a controller. The controller is connected to an external power supply and is a known existing technology, such as a microcontroller, PLC, or industrial computer.

[0020] In use, the wooden floorboards are placed between roller conveyor 4 (number one) and roller conveyor 5 (number two), with the length of the floorboards in the direction of movement. Roller conveyors 4 and 5 clamp the top and bottom ends of the floorboards (the vertical distance between roller conveyors 4 and 5 needs to be determined based on the thickness of the floorboards during manufacturing), enabling forward conveying. When the floorboards move to roller conveyor 6 (number three), roller conveyor 6 and roller conveyor 7 clamp the top and bottom ends of the floorboards (the vertical distance between roller conveyors 6 and 7 needs to be determined based on the thickness of the floorboards during manufacturing). The vertical spacing of roller conveyor 7 is adjusted to allow for leftward conveying. During forward or leftward conveying, the polishing mechanism drives the polishing roller 11 to polish the upper surface of the wood flooring. During forward and leftward conveying, two polishing mechanisms drive the polishing roller 11 to polish the left and right edges and front and back edges of the wood flooring to remove burrs. Compared with existing technologies, this does not require the wood flooring to be rotated, which is beneficial to product quality assurance and the extension of the service life of the device. Furthermore, the first conveying mechanism 1 and the second conveying mechanism 2 do not interfere with each other, meaning that the forward and leftward movement of different wood flooring can be carried out simultaneously without reducing work efficiency.

[0021] The first roller conveyor 4 includes a first support base 12 and a first roller 13; the second roller conveyor 5 includes a second support base 14 and a second roller 15; and the third roller conveyor 6 includes a third support base 16 and a third roller 17. Multiple first rollers 13 are rotatably connected to the first support base 12; multiple second rollers 15 are rotatably connected to the second support base 14; and multiple third rollers 17 are rotatably connected to the third support base 16. All first rollers 13 are located on the same horizontal plane and are parallel to each other. All second rollers 15 are located on the same horizontal plane. All three rollers 17 are parallel to each other and lie on the same horizontal plane. Each of the first support base 12, second support base 14, and third support base 16 is fixed with a first servo motor 18 and is rotatably connected to a worm gear 19. The first servo motor 18 and the worm gear 19 are coaxially connected to achieve synchronous rotation. Each of the first rollers 13, second roller 15, and third roller 17 is coaxially fixed with a worm wheel 20. The worm gear 19 meshes with the worm wheel 20. Each of the first servo motors 18 is electrically connected to the controller.

[0022] like Figure 1 and Figure 2 As shown, by controlling the rotation of the first servo motor 18, the meshing of the worm gear 19 and the worm wheel 20 can cause the first roller 13, the second roller 15, and the third roller 17 to rotate. The self-locking characteristic of the worm wheel 20 and worm gear 19 transmission can prevent the first roller 13, the second roller 15, and the third roller 17 from rotating accidentally on their own, thus ensuring more stable and controllable conveying of wood flooring.

[0023] The No. 4 roller conveyor 7 includes a No. 4 support base 21 and a No. 4 roller 22. The No. 4 support base 21 is rotatably connected to a plurality of No. 4 rollers 22. Each No. 4 roller 22 is in the same horizontal plane and parallel to each other. The polishing mechanism is located in the No. 1 conveying mechanism 1.

[0024] The polishing mechanism includes a first speed-regulating motor 23 and a polishing roller 10. The second support base 14 has the first speed-regulating motor 23 fixed to it and is rotatably connected to the polishing roller 10. The first speed-regulating motor 23 and the polishing roller 10 are coaxially connected to achieve synchronous rotation. The polishing roller 10 is parallel to the first roller 13 and the second roller 15. The first speed-regulating motor 23 is electrically connected to the controller.

[0025] like Figure 3 and Figure 4 As shown, the polishing mechanism can adopt the above structure. By controlling the rotation of the first speed-regulating motor 23, the polishing roller 10 can be driven to rotate, thereby using the polishing roller 10 to contact and rub against the surface of the wood floor to achieve polishing.

[0026] The sanding mechanism includes a second distance adjustment mechanism, a second speed-regulating motor 25, and a sanding roller 11. The first support base 12 and the third support base 16 are respectively equipped with the second distance adjustment mechanism. The second distance adjustment mechanism is used to adjust the distance between the second speed-regulating motor 25 and the wooden floor. The rotating shaft of the second speed-regulating motor 25 is coaxially connected with the sanding roller 11 to achieve synchronous rotation. The circumferential part of the sanding roller 11 is in contact with the two sides of the wooden floor in the direction of movement. Each of the second speed-regulating motors 25 is electrically connected to the controller.

[0027] Furthermore, the sanding mechanism can adopt the above structure. During the process of conveying the wood flooring using the first conveying mechanism 1 and the second conveying mechanism 2, the distance between the second servo motor 26 and the sanding roller 11 and the two sides of the wood flooring movement direction can be adjusted by controlling the second distance adjustment mechanism. This allows the sanding roller 11 to match wood flooring of different widths. The second speed-regulating motor 25 drives the sanding roller 11 to rotate rapidly, so that the sanding roller 11 moves rapidly relative to the edge of the wood flooring, thereby achieving the effect of sanding and deburring.

[0028] The second adjusting mechanism includes a second servo motor 26, a second bidirectional lead screw 27, a guide groove 28, a second main sliding seat 29, a second auxiliary sliding seat 30, and a second compression spring 31. The first support seat 12 and the third support seat 16 are respectively fixed with the second servo motor 26 and the guide groove 28. The first support seat 12 and the third support seat 16 are respectively rotatably connected to the second bidirectional lead screw 27. The external threads of the two axial parts of the second bidirectional lead screw 27 have opposite directions of rotation. The extension direction of the second bidirectional lead screw 27 is the same as that of the adjacent guide groove 28. The guide groove 28 is slidably connected to two second main sliding seats 29 and two second auxiliary sliding seats 30 along its extension direction. The two second main sliding seats 29 and two second auxiliary sliding seats 30 are connected within the guide groove 28. The primary sliding seat 29 and the secondary sliding seat 30 are located on both sides of the wooden floor moving direction. The two secondary sliding seats 29 in the same guide groove 28 are axially threadedly connected to the two parts of the secondary double-acting screw 27. The secondary sliding seat 30 is interlocked with the secondary double-acting screw 27. The secondary sliding seat 30 is closer to the edges of the wooden floor moving direction than the primary sliding seat 29. The secondary sliding seat 30 and the primary sliding seat 29 are fixed together by a compression spring 31. Under the elastic repulsive force of the compression spring 31, the secondary sliding seat 30 tends to move closer to the edges of the wooden floor moving direction. The servo motor 26 is electrically connected to the controller.

[0029] like Figure 3 and Figure 4As shown, the second adjustment mechanism can adopt the above structure. By controlling the second servo motor 26 to rotate forward and backward, and using the threaded connection between the second bidirectional lead screw 27 and the second main sliding seat 29, the two second main sliding seats 29 in the same guide groove 28 can move closer and further away from each other. Thus, through the second compression spring 31 and the second auxiliary sliding seat 30, the two second speed-regulating motors 25 and the grinding roller 11 can move closer and further away from each other, thereby adapting to wood flooring of different widths. The setting of the second compression spring 31 allows the distance between the second auxiliary sliding seat 30 and the second main sliding seat 29 to decrease and increase and then return to its original position. This ensures that when the grinding roller 11 contacts the wood flooring, it will not cause damage to the device or the wood flooring due to the continued approach of the second main sliding seat 29. That is, it provides a safety margin, which makes it easy to manually control the second servo motor 26 to stop in time. At the same time, it also makes the pressure applied by the grinding roller 11 on both sides of the wood flooring movement direction tend to be uniform under the elastic repulsive force of the second compression spring 31, ensuring that the deburring quality tends to be the same.

[0030] The second support base 14 and the third support base 16 are respectively equipped with calibration mechanisms. Each calibration mechanism includes a third servo motor 32, a third bidirectional lead screw 33, a guide rod 34, a third main sliding seat 35, a third auxiliary sliding seat 36, a third compression spring 37, and a contact roller 38. The second support base 14 and the third support base 16 are each fixed with a third servo motor 32, and are rotatably connected to the third bidirectional lead screw 33. The third servo motor 32 is electrically connected to a controller. The rotating shaft of the third servo motor 32 is coaxially connected to the third bidirectional lead screw 33 to achieve synchronous rotation. The external threads of the two axial portions of the third bidirectional lead screw 33 have opposite directions of rotation. The second support base 14 and the third support base 16 are each fixed with multiple guide rods 34. Three guide rods are slidably connected through the two axial portions of the same guide rod 34. The main sliding seat 35 and the auxiliary sliding seat 36 are located on both sides of the moving direction of the wooden floor. A compression spring 37 is fixed between the main sliding seat 35 and the auxiliary sliding seat 36. Under the elastic repulsive force of the compression spring 37, the auxiliary sliding seat 36 tends to move closer to the edges of the moving direction of the wooden floor. The two axial parts of the bidirectional lead screw 33 are respectively threaded through to the main sliding seat 35. The auxiliary sliding seat 36 is rotatably connected to a contact roller 38. The contact roller 38 is perpendicular to the wooden floor and located on both sides of the axial direction of the bidirectional lead screw 33. The contact roller 38 of the same auxiliary sliding seat 36 is arranged correspondingly to each other in the moving direction of the wooden floor.

[0031] like Figure 3 and Figure 4As shown, by controlling the forward and reverse rotation of the No. 3 servo motor 32, and utilizing the threaded connection between the No. 3 bidirectional lead screw 33 and the No. 3 main sliding seat 35, the No. 3 main sliding seats 35 on the same guide rod 34 can move closer and further apart. This, in turn, drives the contact rollers 38 on both sides of the wood flooring's movement direction to move closer and further apart via the No. 3 compression spring 37 and the No. 3 auxiliary sliding seat 36, thereby adjusting the position of the wood flooring and ensuring that the movement direction of the wood flooring is parallel to the edge to be sanded. The No. 3 compression spring 37 allows the distance between the No. 3 auxiliary sliding seat 36 and the No. 3 main sliding seat 35 to decrease and then increase back to its original position. This ensures that when the contact rollers 38 contact the wood flooring, they will not cause damage to the device or the wood flooring due to the continued approach of the No. 3 main sliding seat 35, thus providing a safety margin and facilitating timely manual control of the No. 3 servo motor 32 to stop. At the same time, the pressure applied by the contact rollers 38 on both sides of the wood flooring's movement direction tends to be uniform under the elastic repulsive force of the No. 3 compression spring 37, thus achieving the centering and calibration of the wood flooring's position.

[0032] The sanding roller 11 has a coaxial and annular flared groove 39 on its outer circumference. The minimum width of the flared groove 39 is greater than the thickness of the wood flooring and corresponds horizontally to the edge of the wood flooring. The flared groove 39 contacts and rubs against the edge of the wood flooring to remove burrs, avoiding accidental contact between other parts of the sanding roller 11 and the upper and lower surfaces of the wood flooring, which would reduce the quality of the wood flooring.

[0033] The wood floor polishing and deburring device also includes a lifting mechanism, which includes a base 40, an upper electric push rod 41, and a lower electric push rod 42. The base 40 is fixed to a first support seat 12 and a third support seat 16. Multiple upper electric push rods 41 are fixed to the upper part of the base 40, and multiple lower electric push rods 42 are fixed to the bottom. The bottom end of each upper electric push rod 41 is fixed to a second support seat 14, and the top end of each lower electric push rod 42 is fixed to a fourth support seat 21. The fourth support seat 21 is inserted into the first support seat 12 with a vertical gap. The fourth roller 22 and the first roller 13 are staggered. The first roller 13 corresponds vertically to the second roller 15, and the third roller 17 corresponds vertically to the fourth roller 22.

[0034] like Figure 3 and Figure 4As shown, by controlling the extension and retraction of the upper electric push rod 41 and the lower electric push rod 42, the No. 2 roller conveyor 5 and the No. 4 roller conveyor 7 can be controlled to move up and down respectively, thus adapting to wood flooring of different thicknesses. When the wood flooring moves to the front of the No. 1 roller conveyor 4, by controlling the extension of the lower electric push rod 42, the wood flooring can be lifted and moved closer to the No. 3 roller conveyor 6, thereby using the No. 3 roller conveyor 6 and the No. 4 roller conveyor 7 to transport the wood flooring to the left. Since the No. 4 support seat 21 and the No. 1 support seat 12 are interlocked, a certain amount of floor space can be saved, thus saving costs.

[0035] The fourth support 21 is also equidistantly rotatably connected to a plurality of fifth rollers 43. The spacing between the fifth rollers 43 is smaller than the spacing between the fourth rollers 22. The fifth rollers 43 are in the same plane and parallel to the fourth rollers 22. The top of the outer circumferential wall of the fifth roller 43 is coplanar with the top of the outer circumferential wall of the fourth roller 22.

[0036] Furthermore, since the spacing of roller 5 43 is smaller than that of roller 4 22, roller 4 22 can more smoothly transport the wood flooring to the left when lifting and conveying it. The larger spacing of roller 4 22 also meets the needs of the calibration and sanding mechanisms. Synchronous rotation can be achieved through coaxial connection using known existing technologies such as fixing, welding, couplings, and fastening.

[0037] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
