[0001] This utility model belongs to the technical field of metal box production equipment, and in particular relates to a metal box bottom stacking and feeding device. Background Technology

[0002] The production process of metal boxes involves stacking or loading the bottom of the box. The current practice is to stack the bottom boxes one by one on the material rack, or to take the bottom boxes out one by one from the material rack to achieve stacking or loading.

[0003] Current technology only provides a fixed material rack. Once the rack has finished its work, it needs to be replaced. Furthermore, the rack is limited by the size of the workspace, its height, and the amount of bottom material it can store. This results in poor production continuity and reduced work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a metal box bottom stacking and feeding device, which aims to solve the technical problem that the single material rack structure in the prior art has limited material stacking capacity, affecting the continuity and efficiency of work.

The first support plate and the second support plate are respectively connected and fixed to both sides of the vertical belt and are arranged in an up-down arrangement. When the material rack drive motor drives the vertical belt to rotate, the first support plate and the second support plate move in opposite directions along the vertical direction through the vertical belt.

[0006] Optionally, the material rack lifting mechanism further includes a first guide post, a first guide sleeve, a second guide post, and a second guide sleeve. The first guide post and the second guide post are both vertically spaced and fixed between the first and second material stacking areas of the base plate. The tops of the first guide post and the second guide post are connected and fixed through a top connecting block. The driven wheel is installed at the bottom of the top connecting block and located between the first guide post and the second guide post. The first guide sleeve is slidably sleeved outside the first guide post and connected and fixed to the side of the first support plate. One side of the vertical belt is locked and connected to the first guide post. The second guide sleeve is slidably sleeved outside the second guide post and connected and fixed to the side of the second support plate. The other side of the vertical belt is locked and connected to the second guide post.

[0008] Optionally, the first support plate has a first notch on the side near the second support plate to avoid the second guide post, and the second support plate has a second notch on the side near the first support plate to avoid the first guide post. The second notch and the first notch are arranged in a staggered manner, and the downward projection of the top connecting block falls into the first notch, while the other part falls into the second notch.

[0009] Optionally, the metal box bottom stacking device further includes a limit switch, which includes a movable arm and a trigger. The movable arm is mounted on the base plate, and the trigger is mounted on the first support plate or the second support plate and is used to contact or sense and cooperate with the movable arm to limit the minimum descent stroke of the first support plate or the second support plate.

[0010] Optionally, the metal box bottom stacking device further includes a rack translation mechanism. The rack translation mechanism includes a movable slider, a fixed guide rail, and a rack driving cylinder. The movable slider is connected and fixed to the bottom of the base plate. The fixed guide rail is slidably engaged with the movable slider and is arranged horizontally. The rack driving cylinder is arranged horizontally below the base plate. The piston rod end of the rack driving cylinder is connected and fixed to the bottom of the base plate through a bottom connecting block.

[0011] Optionally, the metal box bottom stacking device further includes a base frame, which is disposed below the base plate, and the fixed guide rail is fixedly installed on the base frame.

[0012] Optionally, the first material stacking area of ​​the base plate is provided with a plurality of first fixing holes at different positions for fixing the first material blocking column, and the second material stacking area of ​​the base plate is provided with a plurality of second fixing holes at different positions for fixing the second material blocking column.

[0013] The metal box bottom stacking device provided in this utility model embodiment has at least one of the following technical effects: In this utility model, the first support plate in the first stacking area is used to stack metal box bottoms in the area surrounded by multiple first baffles. Similarly, the second support plate in the second stacking area is used to stack metal box bottoms in the area surrounded by multiple second baffles. When the first and second support plates are in a lower position, it indicates that more metal box bottoms can be stacked. The height of the first and second support plates is driven by the material rack lifting mechanism. When the material rack drive motor drives the drive wheel to rotate, the vertical belt can rotate around the drive wheel and the driven wheel through the cooperation of the driven wheel. When the vertical belt rotates, it will pull the first and second support plates, which are on opposite sides and in different high and low positions, to move up and down. In this way, when the first support plate is in the lowest position, it can be filled with metal box bottoms. At this time, the second support plate can be used to stack metal box bottoms. By switching the stacking position in this way, the stacking of metal box bottoms is carried out, ensuring the continuity and high efficiency of stacking. Similarly, the feeding process is the opposite. After feeding the metal box bottom of the first support plate, the feeding can be switched to the metal box bottom of the second support plate, thus achieving continuous and efficient material feeding.

The following description is based on the accompanying drawings. Figures 1-8 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this utility model.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0050] In one embodiment of this utility model, such as Figures 3-5 As shown, a metal box bottom stacking and feeding device 20 is provided. Specifically, the metal box bottom stacking and feeding device 20 is applied to, for example... Figures 1-2 The automatic loading and unloading processing equipment for metal box bottoms shown is used for illustration. This equipment includes a metal box bottom processing machine 10, a metal box bottom stacking and loading device 20, and a metal box bottom linear feeding device 30. The metal box bottom processing machine 10 has a processing cavity 11, and a processing platform 12 is formed below the processing cavity 11. The metal box bottom stacking and loading device 20 is located to the side of the metal box bottom processing machine 10 and is used to supply metal box bottoms for processing on the processing platform 12 or to stack metal box bottoms that have been processed on the processing platform 12. The metal box bottom linear feeding device 30 is installed in the metal box bottom processing machine 10 and picks up stacked metal box bottoms from the metal box bottom stacking and loading device 20 and places them onto the processing platform 12, or transports and stacks metal box bottoms that have been processed on the processing platform 12 into the metal box bottom stacking and loading device 20. Specifically, if there are metal box bottoms on the metal box bottom stacking and feeding device 20, the metal box bottom linear feeding device 30 can extend to the metal box bottom stacking and feeding device 20 to pick up the metal box bottoms and send them to the metal box bottom processing machine 10 for processing. Then, the processed metal box bottoms are transported back to the metal box bottom stacking and feeding device 20 for storage. For example, the metal box bottom stacking and feeding device 20 can be arranged on both sides of the metal box bottom processing machine 10. Of course, the metal box bottoms can also be taken out from other production processes by the metal box bottom linear feeding device 30 and sent to the metal box bottom processing machine 10 for processing. Then, the processed ones are transported and stored on the metal box bottom stacking and feeding device 20, thus completing the processing of the metal box bottoms.

[0051] Among them, the metal box bottom processing machine 10 can be a press, rolling machine, flanging machine, etc. Such mechanical equipment can all process the metal box bottom, and such mechanical equipment belongs to the existing technology, so it will not be described in detail here.

[0052] Furthermore, such as Figures 3-5As shown, the metal box bottom stacking and feeding device 20 includes a base plate 21, a first material rack 22, a second material rack 23, and a material rack lifting mechanism 24. The base plate 21 is located on the lower side of the metal box bottom processing machine 10. The base plate 21 divides and arranges a first stacking area and a second stacking area side by side. The first material rack 22 includes a first support plate 221 and a plurality of first baffle posts 222. The second material rack 23 includes a second support plate 231 and a plurality of second baffle posts 232. Each first baffle post 222 is vertically fixed to the first stacking area of ​​the base plate 21. A support plate 221 is located on the first stacking area and has a first strip-shaped hole 2211 through which each of the first baffle posts 222 passes. Each of the second baffle posts 232 is vertically fixed on the second stacking area of ​​the base plate 21. A second support plate 231 is located on the second stacking area and has a second strip-shaped hole 2311 through which each of the second baffle posts 232 passes. Thus, the first support plate 221 can move up and down through the first strip-shaped hole 2211, and the second support plate 231 can move up and down through the second strip-shaped hole 2311. Furthermore, because the holes are strip-shaped, the positions of the first baffle posts 222 and the second baffle posts 232 in the length direction of the first strip-shaped hole 2211 and the second strip-shaped hole 2311, respectively, can be adjusted, thereby adjusting the area enclosed for stacking metal box bottoms to meet the limiting requirements for metal box bottoms of different sizes or shapes. The material rack lifting mechanism 24 includes a material rack drive motor 241, a drive wheel 242, a driven wheel 243, and a vertical belt (not shown). The material rack drive motor 241 is fixed to the bottom of the base plate 21. The drive wheel 242 is fixed to the main shaft of the material rack drive motor 241. The driven wheel 243 is located above the drive wheel 242 and positioned accordingly. The vertical belt connects the drive wheel 242 and the driven wheel 243. The first support plate 221 and the second support plate 231 are respectively connected and fixed to both sides of the vertical belt and arranged in an up-down configuration. When the material rack drive motor 241 drives the vertical belt to rotate, the vertical belt drives the first support plate 221 and the second support plate 231 to move in opposite directions along the vertical direction. Specifically, the first support plate 221 in the first stacking area is used to stack the bottom of the metal box in the area enclosed by multiple first baffles 222. Similarly, the second support plate 231 in the second stacking area is used to stack metal box bottoms in the area enclosed by multiple second baffles 232. When the first support plate 221 and the second support plate 231 are in a lower position, it indicates that a larger number of metal box bottoms can be stacked. The height of the first support plate 221 and the second support plate 231 is driven by the material rack lifting mechanism 24.When the material rack drive motor 241 drives the drive wheel 242 to rotate, the driven wheel 243, in conjunction with it, causes the vertical belt to rotate around the drive wheel 242 and the driven wheel 243. As the vertical belt rotates, it pulls the first support plate 221 and the second support plate 231, which are positioned at opposite heights, causing them to move up and down. Thus, when the first support plate 221 is at its lowest position, it is filled with metal box bottoms. At this point, the second support plate 231 can be used to fill the remaining metal box bottoms. This switching of stacking positions ensures continuous and efficient stacking. Similarly, loading is the opposite: after loading the metal box bottoms onto the first support plate 221, the second support plate 231 can be used for loading, achieving continuous and efficient stacking and loading.

[0053] Thus, the metal box bottom linear feeding device 30 can pick up the metal box bottom from the first support plate 221 or the second support plate 231 and process it on the processing platform 12, or pick up the processed metal box bottom from the processing platform 12 and stack it on the first support plate 221 or the second support plate 231.

[0054] In one embodiment of this utility model, such as Figures 3-5 As shown, the material rack lifting mechanism 24 further includes a first guide post 244, a first guide sleeve 245, a second guide post 246, and a second guide sleeve 247. The first guide post 244 and the second guide post 246 are both vertically spaced and fixed between the first and second material stacking areas of the base plate 21. The tops of the first guide post 244 and the second guide post 246 are connected and fixed through a top connecting block 248. The driven wheel 243 is installed at the bottom of the top connecting block 248 and located between the first guide post 244 and the second guide post 246. The first guide sleeve 245 is slidably sleeved outside the first guide post 244 and connected and fixed to the side of the first support plate 221. One side of the vertical belt is locked and connected to the first guide post 244. The second guide sleeve 247 is slidably sleeved outside the second guide post 246 and connected and fixed to the side of the second support plate 231. The other side of the vertical belt is locked and connected to the second guide post 246. Specifically, the first guide post 244 cooperates with the first guide sleeve 245 to guide the lifting and lowering of the first support plate 221, and the second guide post 246 cooperates with the second guide sleeve 247 to guide the lifting and lowering of the second support plate 231. Thus, when one side of the vertical belt pulls the first guide sleeve 245 up or down along the first guide post 244, the other side of the vertical belt pulls the second guide sleeve 247 down or up along the second guide post 246, moving in an up-and-down manner, ensuring that after one support plate completes its work, the other support plate can begin its work.

[0055] In one embodiment of this utility model, such as Figures 3-5 As shown, there are two first guide posts 244, and the first guide sleeves 245, which are sleeved on the two first guide posts 244, are connected and fixed by a first side connecting block 2451. The side of the first side connecting block 2451 is locked to one side of the vertical belt. There are two second guide posts 246, and the second guide sleeves 247, which are sleeved on the two second guide posts 246, are connected and fixed by a second side connecting block 2471. The side of the second side connecting block 2471 is locked to the other side of the vertical belt. Specifically, the first side connecting block 2451 connects the two first guide posts 244 together, which can improve the stability of the guide and increase the strength to be sufficient to pull the first support plate 221 that is piled up at the bottom of the metal box. At the same time, it can also be locked to the vertical belt. Similarly, the second side connecting block 2471 connects the two second guide posts 246 together, which can improve the stability of the guide and increase the strength to be sufficient to pull the second support plate 231 filled with metal box bottom up. At the same time, it can also be locked to the vertical belt.

[0056] In one embodiment of this utility model, such as Figures 3-5 As shown, the first support plate 221 has a first notch 2212 on the side near the second support plate 231 to avoid the second guide post 246, and the second support plate 231 has a second notch 2312 on the side near the first support plate 221 to avoid the first guide post 244. The second notch 2312 and the first notch 2212 are arranged in a staggered manner. The downward projection of the top connecting block 248 falls into the first notch 2212, and the other part falls into the second notch 2312. Specifically, the first notch 2212 provides space to avoid the second guide post 246, and similarly, the second notch 2312 provides space to avoid the first guide post 244. This allows the first support plate 221 and the second support plate 231 to cooperate with each other through the notches, so that the first support plate 221 and the second support plate 231 are not too far apart due to the first guide post 244 and the second guide post 246 in the middle. This allows the materials piled on the first support plate 221 and the second support plate 231 to be as close as possible, which facilitates switching of working areas.

[0057] In one embodiment of this utility model, such as Figure 3As shown, the metal box bottom stacking device 20 also includes a limit switch 25. The limit switch 25 includes a movable arm 251 and a trigger 252. The movable arm 251 is mounted on the base plate 21, and the trigger 252 is mounted on the first support plate 221 or the second support plate 231, and is used to contact or sense the movable arm 251 to limit the minimum descent stroke of the first support plate 221 or the second support plate 231. Specifically, when the first support plate 221 or the second support plate 231 descends to a set height position, the trigger 252 on it will trigger the movable arm 251 at the corresponding position. This sends a signal to the material rack drive motor 241 of the material rack lifting mechanism 24, causing it to stop controlling the first support plate 221 or the second support plate 231 to continue descending, thus meeting the requirements of safe production.

[0058] In one embodiment of this utility model, such as Figures 4-5 As shown, the metal box bottom stacking and feeding device 20 also includes a rack translation mechanism 26. The rack translation mechanism 26 includes a movable slider 261, a fixed guide rail 262, and a rack driving cylinder 263. The movable slider 261 is fixedly connected to the bottom of the base plate 21. The fixed guide rail 262 is slidably engaged with the movable slider 261 and is horizontally arranged. The rack driving cylinder 263 is horizontally arranged below the base plate 21, and the piston rod end of the rack driving cylinder 263 is fixedly connected to the bottom of the base plate 21 via a bottom connecting block 264. Specifically, the purpose of the rack translation mechanism 26 is to control the movement of the entire base plate 21 in a horizontal position, thereby controlling the movement positions of the first support plate 221 and the second support plate 231, switching between stacking and feeding. When the piston rod of the material rack drive cylinder 263 moves back and forth, the bottom connecting block 264 moves back and forth, which in turn drives the base plate 21 to move back and forth. Guided by the cooperation of the movable slider 261 and the fixed guide rail 262, the base plate 21 moves stably. After the first support plate 221 has completed its work in conjunction with the metal box bottom linear feeding device 30, the material rack drive cylinder 263 drives the base plate 21 to move the second support plate 231 to a suitable position to continue the work in conjunction with the metal box bottom linear feeding device 30. This switching keeps production continuous and efficient.

[0059] In one embodiment of this utility model, such as Figures 3-5 As shown, the metal box bottom stacking device 20 also includes a base frame 27, which is disposed below the base plate 21, and the fixed guide rail 262 is fixedly installed on the base frame 27. Specifically, the base frame 27 provides the installation space for the material rack drive cylinder 263 and the fixed guide rail 262, supports the entire metal box bottom stacking device 20, and facilitates the movement of the metal box bottom stacking device 20 by moving the base frame 27.

[0060] In one embodiment of this utility model, such as Figure 3 As shown, the first stacking area of ​​the base plate 21 has multiple first fixing holes 211 at different positions for fixing the first baffle post 222, and the second stacking area of ​​the base plate 21 has multiple second fixing holes 212 at different positions for fixing the second baffle post 232. Specifically, the variation in the number and position of the first fixing holes 211 is to install the first baffle post 222 in different positions, thus forming different areas to limit the stacking of different metal box bottoms by fixing the first baffle post 222 in different positions. Similarly, the variation in the number and position of the second fixing holes 212 is to install the second baffle post 232 in different positions, thus forming different areas to limit the stacking of different metal box bottoms by fixing the second baffle post 232 in different positions.

[0061] In one embodiment of this utility model, such as Figures 6-8As shown, the metal box bottom linear feeding device 30 includes a frame 31, a suction cup 32, a suction cup bracket 33, a material picking and placing lifting mechanism 34, and a material picking and placing translation mechanism 35. The frame 31 is installed in the metal box bottom processing machine 10 and extends into the processing cavity 11. The material picking and placing lifting mechanism 34 is installed on the frame 31. The material picking and placing translation mechanism 35 includes a mounting base 35a, a translation drive motor 35b, a driving gear 35c, a driven gear 35d, a rack 35e, a first pulley 35f, a second pulley 35g, and a horizontal belt 35h. The mounting base 35a is connected to the driving end of the material picking and placing lifting mechanism 34 and is driven by the material picking and placing lifting mechanism 34 to achieve upward and downward movement. The translation drive motor 35b is vertically installed on the mounting base 35a. The driving gear 35c... A horizontal rack 35e is horizontally positioned below the mounting base 35a and connected to the main shaft of the translation drive motor 35b. The driven gear 35d meshes with the driving gear 35c. The rack 35e is horizontally positioned and meshes with the driven gear 35d. The first pulley 35f and the second pulley 35g are respectively installed at both ends of the rack 35e along its length. The horizontal belt 35h is wound around and connected between the first pulley 35f and the second pulley 35g. The upper side of the horizontal belt 35h is locked to the mounting base 35a. The suction cup bracket 33 is locked to the lower side of the horizontal belt 35h and extends away from the rack 35e. The suction cup 32 is installed on the suction cup bracket 33 and is used to adsorb the bottom of the metal box. The suction cup 32 is located above the processing platform 12. Specifically, the material handling lifting mechanism 34 can control the entire material handling translation mechanism 35 to lift in the height direction through its drive end, thereby driving the suction cup 32 on the suction cup bracket 33 to lift in the height direction. The purpose is to control the metal box bottom picked up by the suction cup 32 to be placed on the processing platform 12 or picked up from the processing platform 12. In the material handling and translation mechanism 35, the translation drive motor 35b drives the drive gear 35c to rotate, the drive gear 35c drives the driven gear 35d to rotate, and the driven gear 35d drives the rack 35e to move horizontally back and forth. The reciprocating motion area of ​​the rack 35e is between the processing platform 12 and the material handling point or stacking point. The reciprocating motion of the rack 35e drives the first pulley 35f and the second pulley 35g connected to it to reciprocate. Since the upper part of the horizontal belt 35h is fixed on the mounting base 35a, the lower part of the horizontal belt 35h will reciprocate with the rack 35e, thereby driving the suction cup bracket 33 locked under the horizontal belt 35h to reciprocate. Thus, the suction cup 32 on the suction cup bracket 33 also reciprocates. This reciprocating motion controls the metal box bottom picked up by the suction cup 32 to be placed on the processing platform 12 or picked up from the processing platform 12.

[0062] More specifically, the suction cup 32 picks up the metal box bottom and places it on the processing platform 12, or picks it up from the processing platform 12. This means picking up the metal box bottom from the first support plate 221 or the second support plate 231 and placing it on the processing table for processing, or picking up the processed metal box bottom from the processing platform 12 and placing it on the first support plate 221 or the second support plate 231. The first support plate 221 and the second support plate 231 can be switched in position to ensure the continuity of material stacking and feeding.

[0063] In one embodiment of this utility model, such as Figure 6 and 8 As shown, the material handling and translation mechanism 35 further includes an upper guide rail 35i, a lower guide rail 35j, an upper slider 35k, and a lower slider 351. The upper guide rail 35i and the lower guide rail 35j are respectively fixed to the top and bottom of the rack 35e. The upper slider 35k and the lower slider 351 are slidably engaged with the upper guide rail 35i and the lower guide rail 35j, respectively. The upper slider 35k is fixedly connected to the bottom of the mounting base 35a, and the lower slider 351 is locked to the lower side of the horizontal belt 35h. Specifically, the upper guide rail 35i and the lower guide rail 35j reciprocate left and right with the rack 35e, and the reciprocating left and right movement is guided by the upper slider 35k fixedly connected to the mounting base 35a. At the same time, the lower slider 351 also moves left and right, and its lower side, along with the horizontal belt 35h, reciprocates left and right with half of the following rack 35e, thus driving the suction cup 32 to reciprocate left and right.

[0064] In one embodiment of this utility model, such as Figures 6-8As shown, the suction cup bracket 33 includes a central connecting block 331, a long strip block 332, a first cantilever bar 333, and a second cantilever bar 334. The central connecting block 331 is locked between the lower slider 351 and the lower side of the horizontal belt 35h. The long strip block 332 is horizontally fixed to the front side of the central connecting block 331. The first cantilever bar 333 and the second cantilever bar 334 are horizontally arranged and vertically connected to the long strip block 332 near its two ends. The suction cup 32 is installed at the bottom of both the first cantilever bar 333 and the second cantilever bar. Specifically, the central connecting block 331 is used to centrally connect the lower slider 351 and the lower side of the horizontal belt 35h, thus connecting the lower side of the horizontal belt 35h and the lower slider 351 into a whole, so as to achieve reciprocating movement with the rack 35e. Furthermore, the elongated block 332 is designed to have sufficient length for the installation of the first cantilever bar 333 and the second cantilever bar 334, allowing the first cantilever bar 333 and the second cantilever bar 334 to be spaced sufficiently apart. This ensures that when the suction cup 32 installed on the first cantilever bar 333 is positioned on the processing platform 12, the suction cup 32 installed on the second cantilever bar 334 can be positioned on the first support plate 221 or the second support plate 231, enabling reciprocating conveying of material loading or stacking to the processing position.

[0065] In one embodiment of this utility model, such as Figures 6-8 As shown, there are two upper sliders 35k and two lower sliders 351. The arrangement of two upper sliders 35k and two lower sliders 351 can improve the stability and reliability of the guide.

[0066] In one embodiment of this utility model, such as Figures 6-8 As shown, the material handling lifting mechanism 34 includes a lifting drive motor 341, a lifting plate 342, a lead screw 343, and a movable nut 344. The lead screw 343 is vertically and rotatably mounted on the frame 31. The lifting drive motor 341 is located at the top of the frame 31 and connected to the lead screw 343. The movable nut 344 is threaded onto the lead screw 343. The lifting plate 342 is connected and fixed to the movable nut 344 and extends outside the frame 31. The mounting base 35a is connected and fixed to the side of the lifting plate 342. Specifically, the lifting drive motor 341 drives the lead screw 343 to rotate, converting the rotational force into controlling the up-and-down movement of the movable nut 344. In this way, the movable nut 344 drives the lifting plate 342 to move up and down, and the lifting plate 342 drives the mounting base 35a to move up and down, thus realizing the control of the up-and-down movement of the entire material handling translation mechanism 35.

[0067] In one embodiment of this utility model, such as Figure 6 and 8As shown, the material handling lifting mechanism 34 further includes a vertical guide rail 345 and a guide slider 346. The vertical guide rail 345 is installed on the front side of the frame 31, and the guide slider 346 is installed on the rear side of the mounting base 35a and slides in cooperation with the vertical guide rail 345. Specifically, the cooperation between the vertical guide rail 345 and the guide slider 346 can ensure that the up and down movement of the mounting base 35a is more stable and reliable.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
