Description

Technical Field

[0001] This invention relates to the field of board processing equipment technology, specifically to a surface treatment equipment and process for modified wood board processing. Background Technology

[0002] In the wood processing industry, modified wood panels are widely used in furniture manufacturing, interior decoration and other fields due to their superior properties obtained after special treatment, such as higher stability, corrosion resistance and environmental friendliness.

[0003] Pre-treatment for wood panel modification requires sanding the surface. Sanding is a crucial step in the modified wood panel processing, directly affecting the surface smoothness, flatness, and quality of subsequent coating processes, and is of great significance in enhancing the product value of modified wood panels. However, current sanding devices for modified wood panels still have many problems in practical applications.

[0004] On the one hand, the sanding process of modified wood panels generates a large amount of sawdust and other debris. If this debris is not removed promptly and effectively, it easily adheres to the surface of the wood panel or accumulates in the contact area between the sanding tool and the wood panel. This not only leads to uneven sanding, resulting in scratches, unevenness, and other defects, affecting the aesthetics and precision of the modified wood panel surface, but may also exacerbate the wear and tear on the sanding tool due to the friction of the debris, shortening the equipment's lifespan and increasing production costs. Although some existing sanding devices are equipped with simple dust collection structures, they often suffer from limited suction range and insufficient suction power, making it difficult to effectively remove the debris generated during the sanding process. On the other hand, modified wood panels typically require thorough sanding on both sides to ensure overall processing quality. However, most sanding equipment currently lacks an automatic flipping function. After sanding one side of the panel, it must be manually flipped and repositioned. This process not only increases the labor intensity of operators but also reduces production efficiency.

[0005] Therefore, the present invention provides a surface treatment device and process for processing modified wood panels to solve the above problems. Summary of the Invention

[0006] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a surface treatment device for modified wood panel processing. This device effectively solves the problems of uneven sanding, scratches, unevenness, and other defects caused by the generation of large amounts of sawdust and dust during the sanding process, which affects the aesthetics and precision of the modified wood panel surface. Furthermore, the friction from the sawdust can exacerbate wear on sanding tools, shortening equipment lifespan and increasing production costs. Additionally, modified wood panels typically require comprehensive sanding on both sides to ensure overall processing quality. However, most current sanding devices lack automatic flipping functionality, requiring manual flipping and repositioning of the wood panel after sanding one side.

The main support frame is equipped with a discharge push plate for pushing the wooden board to slide upward away from the grinding chamber. The feeding push plate is located on the other side of the grinding chamber. The main support frame is equipped with a discharge push hydraulic cylinder for pushing the feeding push plate to slide.

[0016] A modified wood panel processing technology, using the aforementioned surface treatment equipment for modified wood panel processing, includes the following steps: Step 1: Place the wooden board to be processed onto the main support bracket. Use the feeding hydraulic cylinder to push the feeding push plate into the support frame. Then activate the clamping hydraulic cylinder. The extension shaft of the clamping hydraulic cylinder pushes the clamping plate out until it clamps both ends of the wooden board. At this time, the front of the wooden board is facing up. Step 2: Control the retraction of the support frame through the bearing hydraulic cylinder, start the downward pressing hydraulic cylinder to push the downward pressing plate to slide downward until the support groove and the support shaft contact each other, and then push the support plate to slide downward through the downward pressing hydraulic cylinder; Step 3: The hydraulic cylinder pushes the lower pressure plate downward. When the rotating gear and the drive rack mesh, the rotating gear drives the limit block to rotate 180° clockwise. At this time, the back of the wooden board is facing up until the back of the wooden board contacts the bottom sandpaper and brush. The bottom sandpaper is used to sand the front of the wooden board, and the side sanding frame is used to sand the side of the wooden board. At the same time, the brush is used to clean the debris attached to the front of the wooden board.

The rotating gear drives the limit switch to rotate counterclockwise. At this time, the front of the wooden board is facing up. Continue until the lower hydraulic cylinder drives the lower pressure plate to slide upward to the initial position, and the pressing plate slides to the top under the action of the tension spring. Then, the control hydraulic cylinder pushes the rotating control frame to slide, so that the drive rack moves away from the rotating gear. At this time, the lower hydraulic cylinder pushes the lower pressure plate to slide downward again until the back of the wooden board and the bottom surface of the sandpaper come into contact, and the back of the wooden board is sanded. At the same time, the side sanding frame sands the side of the wooden board. After sanding, the lower hydraulic cylinder drives the lower pressure plate to slide upward, and the pressing plate slides to the top under the action of the tension spring. The control hydraulic cylinder pushes the rotating control frame to slide, so that the drive rack slides to the limit position in the direction close to the rotating gear. Step 5: The discharge pusher is pushed by the discharge pusher cylinder to push the discharge pusher plate away from the grinding chamber, thereby pushing the ground wood board out from above the grinding chamber.

[0017] The beneficial effects of this invention are as follows: This invention addresses the problem that modified wood boards generate a large amount of sawdust and dust during the sanding process.

By adding a limiting frame, a rotation control frame, a drive rack, an auxiliary limiting plate, a rotation slot, a rotation gear, and a control hydraulic cylinder, the problem of needing to sand both sides of modified wood panels to ensure overall processing quality can be solved. However, most sanding devices currently lack automatic flipping functionality, requiring manual flipping and repositioning of the wood panel after sanding one side. The bottom surface can be cleaned using sandpaper and brushes by adding a cleaning frame, cleaning brush, guide shaft, and guide groove; The sides of the wood board can be sanded by adding a side sanding stand, a side sanding plate, a sanding spring, and a side sanding cloth.

[0027] Refer to the instruction manual appendix Figure 1-12 A surface treatment device for processing modified wood panels includes a main support frame 1, a grinding chamber 2 is provided on the main support frame 1, a downward hydraulic cylinder 3 is fixedly connected to the upper end of the main support frame 1, a downward pressure plate 4 is fixedly connected to the extended shaft end of the downward hydraulic cylinder 3, the downward pressure plate 4 is located above the grinding chamber 2, and side support plates 5 are fixedly connected to both ends of the downward pressure plate 4, and a support groove 6 is provided at the lower end of the side support plate 5. A support frame 7 is slidably connected above the grinding chamber 2. The support frame 7 is controlled by a support hydraulic cylinder to slide horizontally above the grinding chamber 2. In the initial state, the support hydraulic cylinder pushes the support frame 7 to extend above the grinding chamber 2. At this time, the support frame 7 is used to support the wooden board. Both sides of the grinding chamber 2 are provided with limit grooves 8. A connecting bushing 9 is slidably connected inside the limit groove 8. A support plate 10 is rotatably connected to one end of the connecting bushing 9 near the inside of the grinding chamber 2. The support plate 10 is slidably connected to the inner wall of the grinding chamber 2. A tension spring 11 is installed between the support plate 10 and the grinding chamber 2. In the initial state, the tension spring 11 provides an upward pulling force to pull the support plate 10 upward to the top of the limit groove 8. A support shaft 12 that cooperates with the support groove 6 is fixedly connected to the support plate 10. In use, the lower pressure plate 4 is pushed down by the lower hydraulic cylinder 3 until it is in contact with the support groove 6 and the support shaft 12 at the lower end of the side support plate 5, thereby causing the lower pressure plate 4 to push the support plate 10 down through the support shaft 12.

[0028] A limiting block 13 is fixedly connected to one end of the connecting bushing 9 away from the interior of the grinding chamber 2. A clamping hydraulic cylinder 14 is fixedly installed on the side of the limiting block 13 away from the connecting shaft. A pressure plate 15 is fixedly connected to the extended shaft end of the clamping hydraulic cylinder 14. The pressure plate 15 is used to move towards the interior of the grinding chamber 2 to clamp the wooden board. The connecting bushing 9 is fitted onto the extended shaft of the clamping hydraulic cylinder 14. An extension shaft is fixedly connected to the extended shaft end of the clamping hydraulic cylinder 14, and the other end of the extension shaft is fixedly connected to the pressure plate 15. A long strip-shaped keyway is provided on the extension shaft, and a connecting key that slides in the keyway is fixedly connected inside the connecting bushing 9. This arrangement allows the extension shaft to slide inside the connecting bushing 9 when the extended shaft of the clamping hydraulic cylinder 14 extends, and the connecting key inside the connecting bushing 9 slides inside the keyway. At the same time, when the clamping hydraulic cylinder 14 is controlled to rotate at a certain angle, the connecting bushing 9 simultaneously drives the clamping hydraulic cylinder 14, the connecting bushing 9, and the pressure plate 15 to rotate through the connecting key and the keyway. This arrangement improves the stability of the rotation of the clamping hydraulic cylinder 14.

[0029] In use, the clamping hydraulic cylinder 14 pushes the pressing plates 15 toward each other, thereby clamping the wooden board between the pressing plates 15. When the lower pressing plate 4 pushes the support plate 10 downward through the support shaft 12, the wooden board can move downward synchronously with the connecting sleeve 9, the support plate 10 and the clamping hydraulic cylinder 14.

[0030] Both sides of the grinding chamber 2 are equipped with rotation control structures for controlling the clamping hydraulic cylinder 14 to rotate at a certain angle; The rotation control structure includes a limiting frame 16 fixedly connected to both sides of the grinding chamber 2, a limiting block 13 set as a square, and the limiting block 13 slidably connected inside the limiting frame 16. Both sides of the grinding chamber 2 are slidably connected to a rotation control frame 17. A drive rack 18 is fixedly connected to one side of the rotation control frame 17, and an auxiliary limiting plate 19 is fixedly connected to the other side of the rotation control frame 17. Both sides of the limiting frame 16 are provided with rotation slots 20 that respectively cooperate with the drive rack 18 and the auxiliary limiting plate 19. The end of the limiting block 13 near the clamping hydraulic cylinder 14 is fixedly connected to a rotating gear 21 that cooperates with the drive rack 18. Both sides of the grinding chamber 2 are fixedly connected to a control hydraulic cylinder 22 that pushes the rotation control frame 17 to slide horizontally.

[0031] The drive rack 18 is installed on the side of the rotation control frame 17 away from the grinding chamber 2, so that the rotation of the limit block 13 is not affected when the drive rack 18 and the rotating gear 21 mesh. In the initial state, the control hydraulic cylinder 22 controls the rotation control frame 17 to move to the initial position, so that the drive rack 18 slides to the position where it can mesh with the rotating gear 21.

[0032] The sanding chamber 2 is equipped with a sanding device for sanding wood boards. The sanding device includes a sanding sliding frame 23 that is horizontally slidably connected inside the sanding chamber 2. The sanding chamber 2 is equipped with a linear drive hydraulic cylinder 24 for pushing the sanding sliding frame 23 to slide back and forth inside the sanding chamber 2. Multiple sanding structures are horizontally distributed inside the sanding sliding frame 23. The sanding structure includes two sanding rollers 25 arranged in parallel inside the sanding sliding frame 23. A belt 26 is fitted between the two sanding rollers 25. The belt 26 is spaced with bottom sanding sandpaper 27 and brush 28. The sanding rollers 25 are connected to a circumferential drive device. The circumferential drive device can be a drive motor to directly drive the sanding rollers 25 to rotate.

[0033] In use, the drive motor drives the grinding roller 25 to rotate, and the grinding roller 25 drives the belt 26 to start rotating. The bottom surface grinding sandpaper 27 and brush 28 installed on the belt 26 start to move synchronously with the belt 26. During installation, the height of the brush 28 is slightly higher than that of the bottom surface grinding sandpaper 27, so that the brush 28 can produce a small deformation when subjected to the pressure of the wooden board, thereby cleaning the debris on the surface of the wooden board, without affecting the grinding of the wooden board surface by the bottom surface grinding sandpaper 27. The linear drive hydraulic cylinder 24 pushes the grinding sliding frame 23 to slide back and forth inside the grinding chamber 2, thereby repeatedly grinding the surface of the wooden board and improving the grinding effect.

[0034] The grinding chamber 2 is slidably connected to a cleaning frame 29, which is located below the grinding sliding frame 23. The cleaning frame 29 is equipped with multiple cleaning brushes 30 for cleaning the bottom surface sanding cloth 27 and brush 28. Both ends of the grinding sliding frame 23 are fixedly connected to guide shafts 31, and both ends of the cleaning frame 29 are provided with guide grooves 32 that are slidably connected to the guide shafts 31. The guide grooves 32 are inclined and parallel to each other at both ends of the cleaning frame 29.

[0035] When in use, as the grinding sliding frame 23 slides back and forth inside the grinding chamber 2, the guide shaft 31 slides inside the guide groove 32 to push the cleaning frame 29 to slide in a direction perpendicular to the grinding sliding frame 23, thereby achieving the cleaning of the bottom grinding sandpaper 27 and brush 28 by the cleaning brush 30.

[0036] The bottom of the grinding chamber 2 is detachably connected to a waste collection chamber 33, which is located below the cleaning frame 29 and is used to collect the debris from the grinding process.

[0037] A side sanding frame 34 is fixedly connected to one side of the sanding sliding frame 23. A side sanding plate 35 is slidably connected inside the side sanding frame 34. The side sanding plate 35 has an isosceles trapezoidal cross section. A sanding spring 36 is installed between the side sanding plate 35 and the side sanding frame 34. A side sanding cloth 37 is fixedly connected to the side sanding plate 35. In the initial state, the side sanding plate 35 is pushed to slide closer to the side of the wood board under the action of the sanding spring 36, with the inclined surface of the side sanding plate 35 facing upward.

[0038] In use, when the hydraulic cylinder 3 pushes the lower pressure plate 4 downward to contact the surface and bottom sanding cloth 27 of the wooden board, the side of the wooden board contacts the inclined surface of the side sanding plate 35. After being guided by the inclined surface of the side sanding plate 35, the side of the wooden board pushes the side sanding plate 35 towards the side sanding frame 34 to compress the sanding spring 36. When the hydraulic cylinder 3 pushes the lower pressure plate 4 downward to contact the surface and bottom sanding cloth 27 of the wooden board, the side of the wooden board contacts the side of the side sanding plate 35. When the sanding sliding frame 23 slides inside the sanding chamber 2, the side sanding frame 34 moves synchronously with the sanding sliding frame 23. The side sanding frame 34 drives the side sanding plate 35 to move synchronously, and the side sanding cloth 37 sands the side of the wooden board.

[0039] A sliding plate 38 is slidably connected below the lower pressure plate 4. An auxiliary hydraulic cylinder 39 is provided between the sliding plate 38 and the lower pressure plate 4. A lower pressure rod 40 is fixedly connected to the lower end face of the sliding plate 38.

[0040] Multiple sliding plates 38 are provided on the lower pressure plate 4, and each of the lower pressure plates 4 is rotatably connected to a lower pressure roller 41.

[0041] In the initial state, when the pressing hydraulic cylinder 3 pulls the pressing plate 4 to its highest position, the auxiliary hydraulic cylinder 39 drives the sliding plate 38 to its highest position. After the pressing hydraulic cylinder 3 pushes the pressing plate 4 downward to a predetermined height, the side support plate 5 pushes the support plate 10 downward to its lowest position. After the surface of the wooden board and the bottom sanding cloth 27 come into contact, the pressing hydraulic cylinder 3 stops, and the auxiliary hydraulic cylinder 39 starts to push the sliding plate 38 downward, so that the pressing rod 40 and the upper surface of the wooden board are in contact to provide stable pressure, so that the wooden board is evenly stressed and the sanding stability is improved. A pressure sensor can be installed on the pressing roller 41. When the pressure on the pressing roller 41 reaches a fixed value, the auxiliary hydraulic cylinder 39 stops. When the grinding is completed, when the lower hydraulic cylinder 3 pulls the lower pressure plate 4 to slide upward, the auxiliary hydraulic cylinder 39 first pulls the sliding plate 38 upward to the limit position; this setting makes it easier for the pressure plate 15 to drive the wooden board to rotate, and prevents the lower pressure rod 40 from interfering with it.

[0042] The main support 1 is provided with a feeding push plate 42 for pushing the wooden board to slide closer to the upper part of the grinding chamber 2. The feeding push plate 42 is located on one side of the grinding chamber 2. The main support 1 is provided with a feeding push hydraulic cylinder 43 for pushing the feeding push plate 42 to slide. When in use, place the wooden board on the main support bracket 1, start the feeding push plate 42 to push the wooden board into the support frame 7, and then the clamping plate 15 clamps the two ends of the wooden board.

[0043] The main support 1 is provided with a discharge push plate 44 for pushing the wooden board to slide upward away from the grinding chamber 2. The feeding push plate 42 is located on the other side of the grinding chamber 2. The main support 1 is provided with a discharge push hydraulic cylinder 45 for pushing the feeding push plate 42 to slide.

[0044] After the sanding is completed, the discharge push plate 44 pushes the wooden board off the support frame 7, so that the wooden board returns to the main support frame 1.

[0045] A modified wood panel processing technology, employing a surface treatment device for modified wood panel processing, includes the following steps: Step 1: Place the wooden board to be processed onto the main support 1. Push the feeding push plate 42 into the bearing frame 7 by the feeding push hydraulic cylinder 43. Then start the clamping hydraulic cylinder 14. The extension shaft of the clamping hydraulic cylinder 14 pushes the clamping plate 15 to extend until the two ends of the wooden board are clamped. At this time, the front of the wooden board is facing up. Step 2: Control the bearing frame 7 to retract by the bearing hydraulic cylinder, start the pressing hydraulic cylinder 3 to push the pressing plate 4 to slide downward until the support groove 6 and the support shaft 12 contact, and then push the support plate 10 to slide downward by the pressing hydraulic cylinder 3. Step 3: The hydraulic cylinder 3 pushes the pressure plate 4 downward. When the rotating gear 21 and the drive rack 18 mesh, the rotating gear 21 drives the limit block 13 to rotate 180° clockwise. At this time, the back of the wooden board is facing up until the back of the wooden board contacts the bottom sanding cloth 27 and the brush 28. The bottom sanding cloth 27 is used to sand the front of the wooden board, and the side sanding frame 34 is used to sand the side of the wooden board. At the same time, the brush 28 is used to clean the debris attached to the front of the wooden board. Step 4: After cleaning for a certain period of time, the lower hydraulic cylinder 3 drives the lower pressure plate 4 to slide upward until the rotating gear 21 and the drive rack 18 mesh. The rotating gear 21 drives the limit to rotate counterclockwise by 180°. At this time, the front of the wooden board is facing up. The lower hydraulic cylinder 3 drives the lower pressure plate 4 to slide upward to the initial position. The pressing plate 15 slides to the top under the action of the tension spring 11. Then, the control hydraulic cylinder 22 pushes the rotating control frame 17 to slide, so that the drive rack 18 moves away from the rotating gear 21. At this time, the lower hydraulic cylinder 3 pushes the lower pressure plate 4 to slide downward again until the back of the wooden board and the bottom sandpaper 27 contact, and the back of the wooden board is sanded. At the same time, the side sanding frame 34 sands the side of the wooden board. After the sanding is completed, the lower hydraulic cylinder 3 drives the lower pressure plate 4 to slide upward. The pressing plate 15 slides to the top under the action of the tension spring 11. The control hydraulic cylinder 22 pushes the rotating control frame 17 to slide, so that the drive rack 18 slides to the limit position in the direction close to the rotating gear 21. Step 5: The discharge pusher cylinder 45 pushes the discharge pusher plate 44 away from the grinding chamber 2, thereby pushing the ground wood board out from above the grinding chamber 2.

[0046] In practical use, the wooden board to be processed is placed on the main support 1. The feeding hydraulic cylinder 43 pushes the feeding push plate 42 into the bearing frame 7. Then, the clamping hydraulic cylinder 14 is activated. The extension shaft of the clamping hydraulic cylinder 14 pushes the pressure plate 15 to extend until the two ends of the wooden board are clamped. At this time, the front of the wooden board is facing up. The bearing hydraulic cylinder pushes the bearing frame 7 to retract. The lower pressure plate 4 is pushed down by the lower hydraulic cylinder 3 and slides down to fit into the support groove 6 and support shaft 12 at the lower end of the side support plate 5. This causes the lower pressure plate 4 to push the support plate 10 down through the support shaft 12, thus stretching the tension spring 11.

[0047] When the support plate 10 moves downward, causing the limiting block 13 to slide downward to the rotating slot 20, the rotating gear 21 and the drive rack 18 mesh. At this time, the driving rack 18 and the rotating gear 21 drive the limiting block 13 to rotate 180° clockwise, so that the front of the wooden board faces down. Then, the lower pressure plate 4 continues to slide downward, at which point the bottom sanding cloth 27 and the front of the wooden board are in contact. The drive motor drives the belt 26 to rotate, so that the bottom sanding cloth 27 polishes the front of the wooden board. The brush 28 cleans the debris on the wooden board. When the sandpaper 27 contacts the front and bottom surfaces of the wooden board, the side of the wooden board contacts the inclined surface of the side sanding plate 35. After being guided by the inclined surface of the side sanding plate 35, the side of the wooden board pushes the side sanding plate 35 towards the side sanding frame 34 to compress the sanding spring 36. The side sanding frame 34 moves synchronously with the sanding sliding frame 23, and the side sanding frame 34 drives the side sanding plate 35 to move synchronously. The side of the wooden board is sanded by the side sandpaper 37.

[0048] Subsequently, the hydraulic cylinder 3 pulls the lower plate 4 upward. When the limit block 13 slides upward to the rotating slot 20, the rotating gear 21 and the drive rack 18 mesh. Through the drive rack 18 and the rotating gear 21, the limit block 13 rotates counterclockwise by 180°, so that the back of the wooden board faces down. The hydraulic cylinder 3 pulls the lower plate 4 to continue sliding upward. The support groove 6 at the lower end of the side support plate 5 and the support shaft 12 disengage. Through the tension spring 11, the support plate 10 is pulled upward to the limit position, so that the connecting bushing 9 and the top of the limit groove 8 are in contact.

[0049] Subsequently, the hydraulic cylinder 22 is activated to pull the rotating control frame 17 horizontally, causing the drive rack 18 to move away from the rotating gear 21. The auxiliary limiting plate 19 is then engaged with the rotating slot 20 to prevent the limiting block 13 from rotating freely when it slides to the position of the rotating slot 20, which would cause the back of the wooden board to not face down and affect the sanding effect. Then, the pressing hydraulic cylinder 3 pushes the pressing plate 4 downward to slide down until it is in contact with the support groove 6 at the lower end of the side support plate 5 and the support shaft 12. This allows the pressing plate 4 to push the support plate 10 downward through the support shaft 12, stretching the tension spring 11. The side support plate 5 pushes the support plate 10 downward to its limit position. The back and bottom surfaces of the wooden board are brought into contact with the sanding cloth 27. When the back and bottom surfaces of the wooden board are in contact with the sanding cloth 27, the side of the wooden board is in contact with the inclined surface of the side sanding plate 35. After being guided by the inclined surface of the side sanding plate 35, the side of the wooden board pushes the side sanding plate 35 towards the side sanding frame 34 to compress the sanding spring 36. The side sanding frame 34 moves synchronously with the sanding sliding frame 23. The side sanding frame 34 drives the side sanding plate 35 to move synchronously. The other side of the wooden board is sanded by the side sanding cloth 37. The back of the wooden board is polished by the bottom sanding cloth 27. The debris on the wooden board is cleaned by the brush 28.

[0050] Then, the lower pressure plate 4 is pulled upward by the lower hydraulic cylinder 3 until the support groove 6 at the lower end of the side support plate 5 and the support shaft 12 are disengaged. The support plate 10 is pulled upward to the limit position by the tension spring 11, so that the connecting bushing 9 and the top of the limiting groove 8 are engaged. The hydraulic cylinder 22 is then activated to pull the rotating control frame 17 to move horizontally, so that the drive rack 18 moves towards the direction of the rotating gear 21 and stops at the initial position.

[0051] Then, the bearing frame 7 is extended by the bearing hydraulic cylinder and inserted under the wooden board. The clamping hydraulic cylinder 14 extends and pulls the clamping plate 15 back. At this time, the polished template falls onto the bearing frame 7. The discharge pushing hydraulic cylinder 45 pushes the discharge pushing plate 44 away from the polishing chamber 2, thereby pushing the polished wooden board out from above the polishing chamber 2.

[0052] The aforementioned pressing hydraulic cylinder 3, bearing hydraulic cylinder, clamping hydraulic cylinder 14, control hydraulic cylinder 22, linear drive hydraulic cylinder 24, auxiliary hydraulic cylinder 39, feeding push hydraulic cylinder 43, and discharging push hydraulic cylinder 45 are all connected to the control module, which controls the extension and retraction of their extended ends.

[0053] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
