Description

Technical Field

[0001] This application relates to the field of polishing technology, and in particular to an integrated polishing machine. Background Technology

[0002] Polishing is the process of using polishing tools and abrasive particles or other polishing media to modify the surface of a workpiece, thereby obtaining a smooth surface or a mirror-like gloss. Sometimes it is also used to eliminate gloss.

[0003] In existing polishing operations, workers need to hold the workpiece by hand to polish it. During the polishing process, the friction on the workpiece surface generates high temperatures and emits toxic gases, which can endanger the health of workers. Summary of the Invention

[0004] To address the issue of high temperatures generated by friction on the workpiece surface, this application provides an integrated polishing machine.

[0005] This application provides a polishing integrated machine, which adopts the following technical solution:

[0006] A polishing machine includes a body, a first grinding wheel, a second grinding wheel, a sanding belt, and a spray pipe. The body has a grinding chamber. The first grinding wheel and the second grinding wheel are rotatably connected to the inner wall of the grinding chamber at intervals. The sanding belt is tensioned and connected to the first grinding wheel and the second grinding wheel. The surface of the sanding belt can grind and polish the surface of the workpiece. The spray pipe is connected to the inner wall of the grinding chamber, and water can be sprayed onto the surface of the sanding belt through the spray pipe.

[0007] By adopting the above technical solution, the worker holds the workpiece and places it against the surface of the sanding belt. Grinding wheel one and grinding wheel two rotate on the inner wall of the grinding chamber. The sanding belt is tensioned and connects grinding wheel one and grinding wheel two. The sanding belt grinds and polishes the surface of the workpiece, achieving polishing treatment. At the same time, water is sprayed from the spray pipe onto the surface of the sanding belt. The sanding belt exchanges heat with the water, achieving cooling of the sanding belt. This makes it less likely for the surface of the workpiece to heat up when rubbed, and less likely to emit toxic gases, thereby protecting the health of the workers.

[0008] Optionally, a fan is connected to the machine body, with the air inlet of the fan facing the grinding chamber, and the fan can draw air from the grinding chamber.

[0009] By adopting the above technical solution, the air inlet of the fan faces the grinding chamber. The fan draws air from the grinding chamber and drives outside air into the grinding chamber, thereby achieving airflow in the grinding chamber. This makes it less likely for workers to inhale the air in the grinding chamber, further protecting the health of the workers.

[0010] Optionally, the machine body is connected to a filtration device, which includes a first filter screen, a second filter screen, a drain pipe, and multiple sieve blocks. A drain channel is formed on the inner wall of the grinding chamber. The first filter screen is connected to the inner wall of the drain channel near the grinding chamber. The second filter screen is slidably connected to the inner wall of the drain channel. The filter holes of the first and second filter screens are spaced apart. Multiple sieve blocks are spaced apart on the surface of the second filter screen facing the first filter screen. Each sieve block corresponds one-to-one with the filter hole of the first filter screen. The end of the drain pipe is connected to the machine body, and the inner cavity of the drain pipe communicates with the drain channel. Water in the grinding chamber passes through the first and second filter screens sequentially before entering the drain channel, and the water in the drain channel is discharged through the drain pipe.

[0011] By adopting the above technical solution, water is sprayed onto the surface of the sanding belt through the spray pipe. The water drips onto the bottom wall of the grinding chamber due to its own gravity. The water in the grinding chamber passes through filter screen one and filter screen two in sequence and then enters the drainage channel. The water in the drainage channel is discharged through the drainage pipe, thus draining the water in the grinding chamber. When the filter holes on filter screen one are blocked by impurities, filter screen two is driven to slide closer to filter screen one. Screen block one is embedded into the filter holes of filter screen one, and the screen block drives the impurities in the filter holes to be discharged, thus cleaning filter screen one and ensuring the stability of water filtration by filter screen one.

[0012] Optionally, the filtering device further includes a transmission assembly, which includes an elastic element, a transmission rod, and a cam. The cam is rotatably connected to the inner wall of the grinding chamber, and the cam axis is perpendicular to the axis of the second grinding wheel. One end of the transmission rod is connected to the surface of the second filter screen, and the other end of the transmission rod passes through the first filter screen and abuts against the cam wheel surface. One end of the elastic element in the elastic direction is connected to the inner wall of the drainage channel, and the other end of the elastic element in the elastic direction is connected to the surface of the second filter screen. The elastic element has an elastic force that drives the second filter screen to slide closer to the first filter screen, and the transmission rod surface tends to press against the cam wheel surface.

[0013] By adopting the above technical solution, the elastic element one drives the filter screen two to slide towards the filter screen one, and the transmission rod surface abuts against the cam wheel surface. The cam has a large end and a small end. When the cam rotates on the inner wall of the grinding chamber, the large end of the cam abuts against the transmission rod surface, driving the filter screen two to slide away from the filter screen one. The screen block disengages from the filter holes on the filter screen one. The small end of the cam abuts against the transmission rod surface, driving the filter screen two to slide towards the filter screen one. The screen block embeds into the filter holes on the filter screen one. The screen block drives the impurities in the filter holes on the filter screen one to detach, thereby realizing the automated cleaning of the filter screen one.

[0014] Optionally, the transmission assembly further includes a worm, a worm wheel, a rotating rod, two synchronous pulleys, and a synchronous belt used in conjunction with the synchronous pulleys. The rotating rod is rotatably connected to the inner wall of the grinding chamber, and the axis of the rotating rod is parallel to the axis of the cam. One of the synchronous pulleys is coaxially connected to the cam rotating shaft, and the other synchronous pulley is coaxially connected to the rotating rod. The synchronous belt tensions and connects the two synchronous pulleys. The worm is coaxially connected to the rotating shaft of the grinding wheel, and the worm wheel is coaxially connected to the rotating rod. The worm wheel meshes with the worm.

[0015] By adopting the above technical solution, when the second grinding wheel rotates on the inner wall of the grinding chamber, the worm gear meshes with the worm wheel, driving the transmission rod to rotate on the inner wall of the grinding chamber. The synchronous belt tensions and connects the two synchronous pulleys, driving the cam to rotate on the inner wall of the grinding chamber. No external power device is needed to drive the cam to rotate, reducing energy consumption and thus embodying the concept of energy saving.

[0016] Optionally, the filtration device further includes a cleaning component, which includes a scraper slidably connected to a surface of the filter screen, and the scraping end of the scraper is capable of scraping off impurities from the surface of the filter screen.

[0017] By adopting the above technical solution, the scraper slides on the surface of the filter screen, and the scraping end of the scraper can press against the surface of the filter screen and scrape off the impurities on the surface of the filter screen, thereby cleaning the filter screen and making it less prone to clogging, thus ensuring the stability of the filter screen's water filtration.

[0018] Optionally, the cleaning assembly further includes a connecting rope and an elastic element two. One end of the connecting rope is connected to the surface of the filter screen two, and the other end of the connecting rope passes through the filter screen one and is connected to the scraper plate surface. One end of the elastic element two in the elastic direction is connected to the inner wall of the grinding chamber, and the other end of the elastic element two in the elastic direction is connected to the scraper plate surface. The elastic element two has the elasticity to drive the scraper to slide away from the transmission rod, and the connecting rope maintains a taut tendency.

[0019] By adopting the above technical solution, when filter screen two slides towards filter screen one, the connecting rope loosens, and the elastic element two drives the scraper to slide away from the transmission rod, keeping the connecting rope taut. The scraping end of the scraper presses against the surface of filter screen one and scrapes away impurities from the surface of filter screen one. When filter screen two slides away from filter screen one, the connecting rope receives the power of filter screen two and drives the scraper to slide towards the transmission rod, realizing the back-and-forth sliding of the scraper on the surface of filter screen one. No external power device is needed to drive the scraper to slide, reducing energy consumption and thus embodying the concept of energy saving.

[0020] Optionally, the cleaning assembly further includes a sieve plate, a contact switch, a warning light, and an elastic element three. The inner wall of the grinding chamber facing the scraper has a collection groove for the sieve plate to slide. One end of the elastic element three in the elastic direction is connected to the bottom wall of the collection groove, and the other end of the elastic element three in the elastic direction is connected to the surface of the sieve plate. The elastic element three has the elasticity to drive the sieve plate to slide towards the grinding chamber, and the surface of the sieve plate tends to be flush with the inner wall of the grinding chamber. The warning light is connected to the surface of the machine body, and the contact switch is connected to the inner wall of the collection groove. The warning light is electrically connected to the contact switch. When the contact switch abuts against the sieve plate and conducts, the warning light is energized and illuminates.

[0021] By adopting the above technical solution, the opening of the collection tank faces the scraper. The scraper scrapes against a surface of the filter screen and drives the impurities on the surface of the filter screen into the collection tank. The impurities accumulate on the screen plate surface. The screen plate slides towards the contact switch under the pressure of the impurities. The contact switch presses against the screen plate and conducts electricity. The warning light is energized and illuminates, alerting the staff to clean the impurities on the screen plate surface in time, thereby achieving directional cleaning of the screen plate.

[0022] Optionally, a cooling fan is rotatably connected to the inner wall of the grinding chamber, with the air outlet of the cooling fan facing the surface of the sanding belt.

[0023] By adopting the above technical solution, the exhaust end of the cooling fan faces the surface of the sanding belt, driving the air to impact the surface of the sanding belt, so that the air and the sanding belt can fully contact each other and exchange heat, further improving the heat dissipation efficiency of the sanding belt, making it less likely for the workpiece to overheat during grinding and polishing, thereby ensuring the stability of workpiece processing.

[0024] Optionally, a starting assembly is connected between the cooling fan and the rotating rod. The axis of the rotating rod and the axis of the cooling fan are parallel to each other. The starting assembly includes a first starting gear, a second starting gear, and a thermal expansion and contraction rod. The end of the thermal expansion and contraction rod is coaxially connected to the end of the rotating rod. The first starting gear is coaxially connected to the end of the thermal expansion and contraction rod. The second starting gear is coaxially connected to the rotating shaft of the cooling fan. When the thermal expansion and contraction rod heats up and expands, the first starting gear approaches the second starting gear, and the first starting gear meshes with the second starting gear.

[0025] By adopting the above technical solution, when the thermal expansion rod heats up and expands, the starting gear one approaches the starting gear two, the starting gear one meshes with the starting gear two, the rotating rod rotates on the inner wall of the grinding chamber, driving the cooling fan to rotate on the inner wall of the grinding chamber, thus realizing the directional start of the cooling fan. No external power device is needed to drive the cooling fan to rotate, reducing energy consumption and thus embodying the concept of energy saving.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The arrangement of grinding wheel one, grinding wheel two, sanding belt and spray pipe allows the sanding belt to exchange heat with water, thereby cooling the sanding belt and making it less likely for the workpiece surface to heat up when rubbed, thus preventing the emission of toxic gases and protecting the health of the workers.

[0028] 2. The fan is designed to draw outside air into the grinding chamber, thereby improving airflow within the chamber and making it less likely for workers to inhale air from inside the chamber, thus further protecting their health.

[0029] 3. The installation of filter screen one, filter screen two, drainage pipe and screen block. The screen block drives the impurities in the filter holes to be discharged, thereby cleaning filter screen one and ensuring the stability of water filtration by filter screen one.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses an integrated polishing machine. (Refer to...) Figure 1 and Figure 2The polishing machine includes a body 1, a grinding wheel 1 2, a grinding wheel 2 3, a sanding belt 4, and a spray pipe 5. The bottom of the body 1 abuts against the bottom surface to form a support. The body 1 has a grinding chamber 11. The grinding wheel 1 2 and the grinding wheel 2 3 are rotatably connected to the inner wall of the grinding chamber 11. The axis of the grinding wheel 1 2 is parallel to the length direction of the body 1, and the axis of the grinding wheel 1 2 is parallel to the axis of the grinding wheel 2 3. The sanding belt 4 is tensioned and connected to the grinding wheel 1 2 and the grinding wheel 2 3. The surface of the sanding belt 4 can grind and polish the surface of the workpiece. The diameter of the grinding wheel 1 2 is larger than that of the grinding wheel 2 3, which reduces the contact area between the grinding wheel 1 2 and the grinding wheel 2 3, reduces the contact pressure and friction, reduces energy loss, and increases the rotational speed of the grinding wheel 1 2 and the grinding wheel 2 3.

[0036] Reference Figure 2 The number of spray pipes 5 can be one, two or more. In this embodiment, there are two spray pipes 5. The two spray pipes 5 are installed at intervals on the inner wall of the grinding chamber 11. The water inlet of the spray pipe 5 is connected to an external water source. The water outlet of the spray pipe 5 faces the surface of the sanding belt 4. Water from the external water source can be sprayed out from the water outlet of the spray pipe 5 and sprayed onto the surface of the sanding belt 4. The water and the sanding belt 4 exchange heat, making it difficult for the sanding belt 4 to heat up. This achieves the cooling of the sanding belt 4, making it difficult for the workpiece to heat up and generate toxic gases during the grinding and polishing process, thereby protecting the health of the workers.

[0037] Reference Figure 2 The machine body 1 is equipped with a fan 6, with the air inlet of the fan 6 facing the grinding chamber 11. The fan 6 can draw air from the grinding chamber 11 and drive outside air into the grinding chamber 11, thus promoting the air flow in the grinding chamber 11. This makes it less likely for workers to inhale air from the grinding chamber 11, thereby further improving the safety of workers.

[0038] Reference Figure 2 and Figure 3 The machine body 1 is equipped with a filter device 7, which can filter the water in the grinding chamber 11. The filter device 7 includes a filter screen 71, a filter screen 72, a drain pipe 73, a transmission component 74, a cleaning component 75, and multiple screen blocks 76. A drain channel 12 is opened in the inner wall of the grinding chamber 11. The filter screen 71 is welded and fixed to the inner wall of the drain channel 12 facing the grinding chamber 11. The filter screen 71 can filter impurities in the water in the grinding chamber 11. The filter screen 72 is slidably connected to the inner wall of the drain channel 12. The sliding direction of the filter screen 72 is parallel to the width direction of the machine body 1. The filter holes of the filter screen 71 and the filter holes of the filter screen 72 are spaced apart. Multiple screen blocks 76 are welded and fixed at intervals to the surface of the filter screen 72 facing the filter screen 71. The screen blocks 76 correspond one-to-one with the filter holes of the filter screen 71. The screen blocks 76 can be embedded in the filter holes of the filter screen 71 and scrape the impurities in the filter holes.

[0039] Reference Figure 2 and Figure 3One end of the drain pipe 73 is fixed to the surface of the machine body 1 via a flange, and the other end of the drain pipe 73 is connected to the water storage tank. The inner cavity of the drain pipe 73 is connected to the drain channel 12. When the filter screen 72 slides away from the filter screen 71, the screen block 76 disengages from the filter holes on the filter screen 71. The water in the grinding chamber 11 passes through the filter screen 71 and the filter screen 72 in sequence and then enters the drain channel 12. The water in the drain channel 12 is discharged into the water storage tank through the drain pipe 73, thereby achieving the removal of impurities and discharge of the water in the grinding chamber 11, realizing the reuse of water resources, reducing water waste, and thus embodying the concept of energy conservation.

[0040] Reference Figure 2 and Figure 3 When the filter holes on filter screen 71 are blocked, filter screen 72 is driven to slide closer to filter screen 71. Screen block 76 is embedded into the filter holes of filter screen 71 in a corresponding manner. Screen block 76 drives the impurities in the filter holes to detach, thereby cleaning the surface of filter screen 71 without disassembling filter screen 71, thus facilitating the cleaning of filter screen 71.

[0041] Reference Figure 2 and Figure 3 The transmission assembly 74 is installed between the second filter screen 72 and the second grinding wheel 3. The transmission assembly 74 can receive the power of the second grinding wheel 3 and drive the second filter screen 72 to slide. The transmission assembly 74 includes an elastic element 741, a transmission rod 742, a cam 743, a worm gear 744, a worm wheel 746, two synchronous pulleys 747, and a synchronous belt 748 used in conjunction with the synchronous pulleys 747. The cam 743 is rotatably connected to the inner wall of the grinding chamber 11. The axis of the cam 743 is parallel to the height direction of the machine body 1. One end of the transmission rod 742 is welded and fixed to the surface of the second filter screen 72, and the other end of the transmission rod 742... The filter screen 71 passes through the outer wall and abuts against the surface of the cam 743. The elastic element 741 can be a compression spring or a tension spring. In this embodiment, the elastic element 741 is a compression spring with a certain deformation capacity. One end of the elastic element 741 in the direction of elastic force is fixed to the inner wall of the drainage channel 12, and the other end of the elastic element 741 in the direction of elastic force is fixed to the surface of the filter screen 72. The direction of elastic force of the elastic element 741 is parallel to the width direction of the body 1. The elastic element 741 has the elastic force to drive the filter screen 72 to slide towards the filter screen 71, and the transmission rod 742 tends to press against the surface of the cam 743.

[0042] Reference Figure 2 and Figure 3The cam 743 has a large end and a small end. When the rod surface of the transmission rod 742 abuts against the large end of the cam 743, it drives the filter screen 72 to slide away from the filter screen 71, and the screen block 76 disengages from the filter holes on the surface of the filter screen 71. When the rod surface of the transmission rod 742 abuts against the small end of the cam 743, it drives the filter screen 72 to slide closer to the filter screen 71, and the screen block 76 embeds into the filter holes on the surface of the filter screen 71, and scrapes away the impurities in the filter holes, thereby achieving directional cleaning of the inner wall of the filter holes.

[0043] Reference Figure 2 and Figure 3 The rotating rod 745 is rotatably connected to the inner wall of the grinding chamber 11. The axis of the rotating rod 745 and the axis of the cam 743 are parallel to each other. One synchronous pulley 747 is coaxially fixed on the rotating shaft of the cam 743, and the other synchronous pulley 747 is coaxially fixed on the rotating rod 745. The synchronous belt 748 tensions and connects the two synchronous pulleys 747. The worm gear 744 is coaxially fixed on the rotating shaft of the second grinding wheel 3, and the worm wheel 746 is coaxially fixed on the rotating rod 745. The worm wheel 746 meshes with the worm gear 744. When the second grinding wheel 3 rotates on the inner wall of the grinding chamber 11, the worm gear 744 meshes with the worm wheel 746, driving the rotating rod 745 to rotate around its own axis. The synchronous belt 748 tensions and connects the two synchronous pulleys 747, driving the cam 743 to rotate on the inner wall of the grinding chamber 11. No external power device is needed to drive the cam 743 to rotate, reducing energy consumption and thus embodying the concept of energy saving.

[0044] Reference Figure 2 and Figure 3 The cleaning component 75 is installed on the inner wall of the grinding chamber 11. The cleaning component 75 can clean impurities from the surface of the filter screen 71. The cleaning component 75 includes a scraper 751, a connecting rope 752, an elastic element 753, a sieve plate 754, a contact switch 755, a warning light 756, and an elastic element 757. The scraper 751 is slidably connected to the surface of the filter screen 71. The sliding direction of the scraper 751 is parallel to the height direction of the machine body 1. The scraping end of the scraper 751 presses against the surface of the filter screen 71 and scrapes away impurities. One end of the connecting rope 752 is fixed to the filter screen 71. 72 faces the surface of filter screen 71, and the other end of the connecting rope 752 passes through the surface of filter screen 71 and is fixed to the scraper 751. The elastic element 753 can be a compression spring or a tension spring. In this embodiment, the elastic element 753 is a compression spring and has a certain deformation capacity. One end of the elastic element 753 in the direction of elastic force is fixed to the inner wall of the grinding cavity 11, and the other end of the elastic element 753 in the direction of elastic force is fixed to the scraper 751. The elastic element 753 has the elastic force to drive the scraper 751 to slide away from the transmission rod 742, and the connecting rope 752 remains taut.

[0045] Reference Figure 2 and Figure 3When the large end of cam 743 abuts against the rod surface of transmission rod 742, it drives filter screen 2 72 to slide away from filter screen 1 71, and screen block 76 disengages from the filter holes of filter screen 1 71. Connecting rope 752 receives the power of filter screen 2 72 and drives scraper 751 to slide closer to transmission rod 742. Scraper 751 scrapes away impurities from the surface of filter screen 1 71. When the small end of cam 743 abuts against the rod surface of transmission rod 742, it drives filter screen 1 71 to slide closer to filter screen 1 71, and the screen holes are embedded in the filter holes of filter screen 1 71. Connecting rope 752 is in a slack state, and elastic element 2 753 drives scraper 751 to slide away from transmission rod 742. Scraper 751 scrapes away impurities from the surface of filter screen 1 71, realizing the back-and-forth sliding of scraper 751 on the surface of filter screen 1 71, thereby ensuring directional cleaning of the surface of filter screen 1 71.

[0046] Reference Figure 2 and Figure 3 The inner wall of the grinding chamber 11 facing the scraper 751 is provided with a collection groove 13 for the sieve plate 754 to slide. The sliding direction of the sieve plate 754 is parallel to the height direction of the machine body 1. The surface of the sieve plate 754 is for impurities to accumulate. Water in the impurities enters the collection groove 13 after being screened by the sieve plate 754. The elastic element 757 can be a compression spring or a tension spring. In this embodiment, the elastic element 757 is a compression spring with a certain deformation capability. One end of the elastic element 757 in the elastic direction is fixed to the surface of the sieve plate 754, and the other end of the elastic element 757 in the elastic direction is fixed to the bottom wall of the collection groove 13. The elastic element 757 has the elastic force to drive the sieve plate 754 to slide towards the grinding chamber 11, and the surface of the sieve plate 754 tends to be flush with the bottom wall of the grinding chamber 11.

[0047] Reference Figure 2 and Figure 3 The collection tank 13 is connected to the drainage channel 12, and a one-way valve 8 is installed on the inner wall of the collection tank 13 near the drainage channel 12.

The warning light 756 is installed on the surface of the machine body 1, and the contact switch 755 is installed on the inner wall of the collection tank 13. The contact switch 755 is electrically connected to the warning light 756. When the contact switch 755 abuts against the screen plate 754 and conducts, the warning light 756 is energized and illuminates, alerting the staff to clean the impurities on the surface of the screen plate 754 in time, thereby improving the ease of use of the polishing machine for the staff.

[0048] Reference Figure 2 and Figure 3A cooling fan 9 is rotatably connected to the bottom wall of the grinding chamber 11. The air outlet of the cooling fan 9 faces the surface of the sanding belt 4. The axis of the cooling fan 9 and the axis of the rotating rod 745 are parallel to each other. The cooling fan 9 drives the air to impact the surface of the sanding belt 4. The sanding belt 4 exchanges heat with the air, further improving the cooling efficiency of the sanding belt 4 and making it less likely to overheat during operation, thereby ensuring the stability of grinding and polishing the workpiece.

[0049] Reference Figure 2 and Figure 3 A starting assembly 10 is installed between the cooling fan 9 and the rotating rod 745.

The starting assembly 10 includes a starting gear 101, a starting gear 102, and a thermal expansion and contraction rod 103. The thermal expansion and contraction rod 103 can be made of rubber or nylon. In this embodiment, the thermal expansion and contraction rod 103 is made of nylon, which has a certain coefficient of thermal expansion. One end of the thermal expansion and contraction rod 103 is coaxially fixed to the end of the rotating rod 745. The other end of the rod 103 is coaxially fixed to the starting gear 101, and the starting gear 2 102 is coaxially fixed to the rotating shaft of the cooling fan 9. When the temperature inside the grinding chamber 11 rises, the thermal expansion and contraction rod 103 expands due to the increased temperature. The thermal expansion and contraction rod 103 drives the starting gear 101 to approach the starting gear 2 102. The starting gear 101 meshes with the starting gear 2 102, driving the cooling fan 9 to rotate on the bottom wall of the grinding chamber 11. No external power device is needed to drive the cooling fan 9 to rotate, reducing energy consumption and thus embodying the concept of energy saving.

[0050] The implementation principle of the polishing integrated machine in this application embodiment is as follows: the operator holds the workpiece and puts it against the surface of the sanding belt 4. The first grinding wheel 2 and the second grinding wheel 3 rotate on the inner wall of the grinding chamber 11. The sanding belt 4 is tensioned and connected to the first grinding wheel 2 and the second grinding wheel 3. The sanding belt 4 grinds and polishes the surface of the workpiece to achieve the polishing treatment of the workpiece. At the same time, water is sprayed from the spray pipe 5 onto the surface of the sanding belt 4. The sanding belt 4 exchanges heat with the water to cool down the sanding belt 4, so that the surface of the workpiece is not easy to heat up when it is rubbed and is not easy to emit toxic gases, thereby protecting the health of the operator.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
