Description

Technical Field

[0001] The present application relates to the technical field of fish fillet packaging, and in particular to a fish fillet weighing and packaging machine. Background Art

[0002] Fish are cold-blooded aquatic vertebrates covered with bony scales, breathing with gills, swimming through the swinging of the tail and trunk and the coordinated action of the fins, and feeding with the upper and lower jaws. They belong to the subphylum Vertebrata in the phylum Chordata, and are also delicious food on people's tables. With the continuous improvement of living standards, fish fillets have gradually appeared in people's field of vision. Dried fish fillets need to be packaged during the production process.

[0003] The prior art also proposes an improved solution for fish fillet packaging. For example, publication number CN111392105A discloses a fish fillet weighing continuous conveying packaging device including a fish fillet conveying device, a positioning marking part, a fish fillet weighing device and a fish fillet receiving bucket; wherein the fish fillet conveying device includes a fish fillet conveyor belt for conveying fish fillets; a plurality of positioning marking parts are arranged on the surface of the fish fillet conveyor belt and are evenly distributed along the moving direction of the fish fillet conveyor belt; a plurality of fish fillet weighing devices are distributed on both sides of the fish fillet conveyor device. The provided fish fillet weighing continuous conveying packaging device has a simple design and layout, is efficient in bagging and packaging fish fillets, and is convenient for saving time.

[0004] Although the above technical solution can continuously package fish fillets, there are still other problems in the specific operation. For example, when packaging fish fillets, it is necessary to ensure that the weight of the fish fillets inside the packaging bag is constant, but the process of screening the fish fillets and selecting constant weight is relatively troublesome, which affects the packaging.

[0005] Therefore, it is necessary to provide a fish fillet weighing and packaging machine to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] The technical solution adopted by the present application to solve its technical problems is: a fish fillet weighing and packaging machine, including a workbench, the workbench is composed of a plurality of fixed brackets, a feed tray is installed above the workbench through a support plate, and the feed tray is used to transport the fish fillets evenly; an inclined dividing plate is installed on the side above the workbench close to the feed tray, a conveyor belt is provided on the side above the workbench close to the inclined dividing plate, a packaging mechanism is provided on the side above the workbench close to the conveyor belt, the packaging mechanism is used to package the fish fillets, a dividing mechanism is provided inside the inclined dividing plate, and the dividing mechanism is used to screen the fish fillets for uniformity; a recovery belt is provided above the workbench and below the packaging mechanism.

[0008] Furthermore, an L-shaped support plate is fixedly installed above the workbench, the lower end surface of the feed tray is rotatably set on the end of the L-shaped support plate, and the bottom of the feed tray is connected to the output end of the motor, and an annular plate is fixedly installed on the side of the workbench above the L-shaped support plate, a notch is opened on the surface of the annular plate, and the notch corresponds to the inclined dividing plate, an annular baffle is installed on the inner side of the annular plate, the annular plate and the annular baffle are arranged above the feed tray, and the bottom ends of the annular plate and the annular baffle are in contact with the upper surface of the feed tray but not fixedly connected.

[0009] Furthermore, the interior of the conveyor belt is transported by two groups of transmission wheels, and the end of one group of transmission wheels is connected to the output end of the motor; the inclined surface of the inclined material dividing plate is provided with a shielding groove, and a shielding plate 1 is slidably arranged inside the shielding groove, and a shielding plate 2 is arranged on the lower side of the inclined surface of the inclined material dividing plate; a driving unit is arranged at the end of one group of transmission wheels, and the driving unit is used to control the movement of shielding plates 1 and 2.

[0010] Furthermore, the driving unit includes a belt arranged on the outer surface of one group of transmission wheels, a rotating shaft is rotatably arranged on one side above the workbench close to the transmission wheel, the belt is sleeved on the rotating shaft and the outer peripheral surface of one group of transmission wheels, a cam is fixedly connected to the outer peripheral surface of the rotating shaft, and a support frame is commonly installed on the outer walls of the baffle plate 1 and the baffle plate 2, and an arc block is installed at the bottom of the support frame at the position corresponding to the cam.

[0011] Furthermore, a limit plate is arranged on one side above the workbench near the support frame, and the support frame is slidably arranged on the side wall of the limit plate by a sliding rod, and a spring is arranged at the contact position between the sliding rod and the inner wall of the limit plate, and the shape of the baffle plate 1 is adapted to the shape of the baffle groove; during operation, when the support frame moves, the support frame will move on the side wall of the limit plate through the sliding rod, and the sliding rod will drive the spring in contact with it to stretch, and when the convex surface of the cam is separated from the arc block, under the gravity of the support frame, the elastic force of the spring and the limitation of the sliding rod by the limit plate, the baffle plate 1 and the baffle plate 2 can be restored to their initial positions, thereby facilitating the constant weight transportation of fish fillets.

[0012] Furthermore, the packaging mechanism includes two frames installed above the workbench, and a temporary storage ring is arranged between the two frames. The two temporary storage rings are used to place packaging bags, and the openings of the temporary storage rings correspond to the conveyor belt.

[0013] Furthermore, the packaging mechanism also includes an electric push rod slidably arranged inside the two frames, and heat sealing strips are installed at the ends of the two electric push rods. A recycling unit is arranged inside the two frames, and the recycling unit is used to recycle the heat-sealed packaging bags.

[0014] Furthermore, the recovery unit includes rotating plates respectively installed on the outer walls of the temporary storage ring, and the rotating plates are rotatably arranged inside the frame through a rotating rod. An L-shaped pressure block is fixedly installed on the telescopic end of the electric push rod, and extrusion blocks are installed on the surface of the rotating plate corresponding to the end of the L-shaped pressure block.

[0015] Furthermore, a rotating groove adapted to the rotating plate is opened inside the frame, a torsion spring is arranged in the rotating groove, and the torsion spring is sleeved on the surface of the rotating rod at the end of the rotating plate; when working, when the rotating plate rotates, the rotating plate will simultaneously drive the rotating rod at its end to rotate, and drive the torsion spring to contract. When the packaged fish fillets fall, the two electric push rods are controlled to approach each other, so that the L-shaped pressing block is away from the extrusion block. Then, under the recovery of the elastic force of the torsion spring, the two temporary storage rings will return to the initial position, thereby facilitating the subsequent continued packaging of the fish fillets.

[0016] Furthermore, the recovery belt is connected through an external transmission roller, and the top of the temporary storage ring is connected to an external packaging bag conveyor line; when the packaged fish fillets fall onto the recovery belt below, new packaging bags are placed inside the two restored temporary storage rings through the external packaging bag conveyor line, and at this time, the fish fillets after the material is divided just fall from the top of the conveyor belt, so that continuous packaging of the fish fillets can be achieved; it should be noted that the way the external packaging bag conveyor line conveys the new packaging bags is a prior art and will not be described in detail in the embodiments of the present invention.

[0017] The beneficial effect of the present application is as follows: in a fish fillet weighing and packaging machine provided by the present application, the transmission wheel will drive the baffle plate 2 and the baffle plate 1 to move upwards through the driving unit, at which time the baffle plate 2 no longer blocks the fish fillets, and the baffle plate 1 will block the fish fillets on the other side, so the fish fillets between the baffle plate 2 and the baffle plate 1 will fall onto the conveyor belt; subsequently, through the action of the driving unit, the baffle plate 1 and the baffle plate 2 can be restored, so that under the intermittent push of the baffle plate 1 and the baffle plate 2, the amount of fish fillets falling each time is the amount between the baffle plate 1 and the baffle plate 2, so the amount of fish fillets conveyed each time is constant, that is, the weight is constant, which is convenient for the subsequent packaging of fish fillets of constant weight.

[0018] When the raised surface of the cam separates from the arc block, under the action of gravity, baffle plate 1 and baffle plate 2 will return to their initial positions, thereby facilitating the subsequent constant screening of fish fillets. This design can ensure that the number and weight of fish fillets falling between baffle plate 1 and baffle plate 2 are the same each time, and can be just packaged in subsequent packaging bags.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0034] like Figure 1-9 As shown, the present application provides a fish fillet weighing and packaging machine, comprising a workbench 1, the workbench 1 is composed of a plurality of fixed brackets, a feeding tray 2 is installed above the workbench 1 through a support plate, and the feeding tray 2 is used to transport the fish fillets uniformly; an inclined material dividing plate 3 is installed above the workbench 1 on a side close to the feeding tray 2, a conveyor belt 4 is arranged above the workbench 1 on a side close to the inclined material dividing plate 3, a packaging mechanism is arranged above the workbench 1 on a side close to the conveyor belt 4, and the packaging mechanism is used to package the fish fillets, and a material dividing mechanism is arranged inside the inclined material dividing plate 3, and the material dividing mechanism is used to screen the fish fillets uniformly; a recovery belt 5 is arranged above the workbench 1 and below the packaging mechanism;

[0035] During operation, in the initial state, the piles of fish fillets are located inside the feeding tray 2. The feeding tray 2 can feed the fish fillets one by one onto the inclined dividing plate 3. The dividing mechanism can then screen the fish fillets according to a constant weight. The conveyor belt 4 then conveys the fish fillets of constant weight to the packaging mechanism. Finally, the packaged fish fillets can be recycled through the recycling belt 5 to facilitate subsequent operations. The dividing mechanism can ensure that the weight of the fish fillets packaged each time is constant, ensuring that they are packaged in subsequent packaging bags. The dividing mechanism can also enable the fish fillets to be automatically packaged and recycled, saving the labor of the staff.

[0036] An L-shaped support plate 101 is fixedly installed above the workbench 1, the lower end surface of the feed tray 2 is rotatably set at the end of the L-shaped support plate 101, and the bottom of the feed tray 2 is connected to the output end of the motor, and an annular plate 6 is fixedly installed on the side of the workbench 1 close to the L-shaped support plate 101, and a notch is opened on the surface of the annular plate 6, and the notch corresponds to the inclined dividing plate 3, and an annular baffle 7 is installed on the inner side of the annular plate 6, and the annular plate 6 and the annular baffle 7 are arranged above the feed tray 2, and the bottom ends of the annular plate 6 and the annular baffle 7 are in contact with the upper surface of the feed tray 2 but are not fixedly connected;

[0037] During operation, when the pile of fish fillets is placed above the feeding tray 2, the feeding tray 2 is controlled to rotate by the motor. Since the bottom ends of the annular plate 6 and the annular baffle 7 are in contact with the upper surface of the feeding tray 2 but not fixed, when the feeding tray 2 rotates, the annular plate 6 and the annular baffle 7 will limit the fish fillets to a certain extent, and enter the smaller gap between the annular plate 6 and the annular baffle 7 along the side wall of the annular baffle 7. Figure 2 As shown, the fish fillets will then fall along the notch on the surface of the annular plate 6 to the inclined surface of the inclined dividing plate 3 below. This design can facilitate the release of the fish fillets one by one, which is beneficial for subsequent screening and packaging of the fish fillets according to a constant weight, and the operation is more convenient.

[0038] The interior of the conveyor belt 4 is transported by two groups of transmission wheels 401, and the end of one group of transmission wheels 401 is connected to the output end of the motor; the inclined surface of the inclined material dividing plate 3 is provided with a shielding groove 8, and a shielding plate 1 9 is slidably arranged inside the shielding groove 8, and a shielding plate 2 10 is arranged on the lower side of the inclined surface of the inclined material dividing plate 3, and a driving unit is arranged at the end of one group of transmission wheels 401, and the driving unit is used to control the movement of the shielding plate 1 9 and the shielding plate 2 10;

[0039] When working, in the initial state, the positions of the shielding plate 1 9 and the shielding plate 2 10 are as shown in the figure. Figure 4 and Figure 5 As shown, when the feeding plate 2 drops the fish fillets uniformly onto the inclined surface of the inclined material distribution plate 3, the fish fillets will slide down to the side of the shielding plate 2 10 in an array. When the transmission wheel 401 is rotating, the transmission wheel 401 will drive the shielding plate 2 10 and the shielding plate 1 9 to move up to the position shown in the attached figure through the driving unit. Figure 6 As shown in the figure, at this time, the shielding plate 10 no longer blocks the fish fillet, and the shielding plate 19 blocks the fish fillet on the other side, so the fish fillet between the shielding plate 10 and the shielding plate 19 will fall onto the conveyor belt 4; then, through the action of the driving unit, the shielding plate 19 and the shielding plate 10 can be restored to the state shown in the figure. Figure 4 and Figure 5 In the initial position, the shielding plate 1 9 and the shielding plate 2 10 are pushed intermittently, that is, the amount of fish fillets falling each time is the amount between the shielding plate 1 9 and the shielding plate 2 10, so the amount of fish fillets conveyed each time is constant, that is, the weight is constant, which is convenient for subsequent packaging of fish fillets of constant weight.

[0040] It should be noted that the weight and shape of each fish fillet in the present invention are the same.

[0041] The driving unit includes a belt 402 arranged on the outer surface of one group of transmission wheels 401, a rotating shaft 11 is rotatably arranged on one side of the workbench 1 close to the transmission wheel 401, the belt 402 is sleeved on the rotating shaft 11 and the outer peripheral surface of one group of transmission wheels 401, a cam 12 is fixedly connected to the outer peripheral surface of the rotating shaft 11, and a support frame 13 is installed on the outer walls of the shielding plate 1 9 and the shielding plate 2 10, and an arc block 14 is installed at the bottom of the support frame 13 at a position corresponding to the cam 12;

[0042] During operation, when the transmission wheel 401 drives the conveyor belt 4 to rotate, the transmission wheel 401 drives the rotating shaft 11 to rotate through the belt 402, and the rotating shaft 11 drives the cam 12 on its surface to rotate. During the rotation of the cam 12, its convex surface contacts and squeezes the arc surface of the arc block 14, so that the arc block 14 drives the support frame 13, the shielding plate 1 9 and the shielding plate 2 10 to move up to the attached Figure 6 As shown, the fish fillets will slide to the surface of the conveyor belt 4 as described above, and when the raised surface of the cam 12 is separated from the arc block 14, under the action of gravity, the baffle plate 1 9 and the baffle plate 2 10 will return to their initial positions, thereby facilitating the subsequent constant screening of the fish fillets. Such a design can ensure that the number and weight of the fish fillets falling between the baffle plate 1 9 and the baffle plate 2 10 are the same each time, and can be just packaged in the subsequent packaging bags.

[0043] A limit plate 15 is arranged on one side above the workbench 1 near the support frame 13, and the support frame 13 is slidably arranged on the side wall of the limit plate 15 by a sliding rod, and a spring is arranged at the contact position between the sliding rod and the inner wall of the limit plate 15, and the shape of the baffle plate 19 is adapted to the shape of the baffle groove 8; during operation, when the support frame 13 moves, the support frame 13 will move on the side wall of the limit plate 15 through the sliding rod, and the sliding rod will drive the spring in contact with it to stretch, and when the convex surface of the cam 12 is separated from the arc block 14, under the gravity of the support frame 13, the elastic force of the spring and the limitation of the sliding rod by the limit plate 15, the baffle plate 19 and the baffle plate 2 10 can be restored to their initial positions, thereby facilitating the constant weight conveying of fish fillets.

[0044] The packaging mechanism includes two frames 16 installed above the workbench 1, and a temporary storage ring 17 is arranged between the two frames 16. The two temporary storage rings 17 are used to place packaging bags, and the openings of the temporary storage rings 17 correspond to the conveyor belt 4;

[0045] During operation, when fish fillets of constant weight are transmitted by the conveyor belt 4, the fish fillets will fall into the packaging bags in the two temporary storage rings 17, and then the opening of the packaging bag can be heat-sealed by the packaging mechanism to facilitate subsequent operations on the fish fillets.

[0046] The packaging mechanism also includes an electric push rod 18 slidably arranged inside the two frames 16, and heat-sealing strips 181 are installed at the ends of the two electric push rods 18. A recovery unit is arranged inside the two frames 16, and the recovery unit is used to recycle the packaging bags that have been heat-sealed. During operation, when fish fillets of a constant weight fall into the packaging bag, the two electric push rods 18 are controlled to move so that the telescopic ends of the two electric push rods 18 drive the heat-sealing strips 181 to approach each other, and then the two heat-sealing strips 181 will seal the opening of the packaging bag. Subsequently, under the action of the recovery mechanism, the packaging bag that has been heat-sealed can be recovered and fall above the recovery belt 5, thereby realizing the function of automatic packaging of fish fillets.

[0047] The recovery unit includes rotating plates 19 respectively installed on the outer wall of the temporary storage ring 17, and the rotating plates 19 are rotatably arranged inside the frame 16 through a rotating rod. An L-shaped pressing block 20 is fixedly installed at the telescopic end of the electric push rod 18, and an extrusion block 21 is installed on the surface of the rotating plate 19 and at the end of the L-shaped pressing block 20;

[0048] During operation, when the heat sealing of the packaging bag is completed, the two heat sealing strips 181 are moved away from each other by controlling the telescopic ends of the two electric push rods 18 to move away from each other, and the two electric push rods 18 will drive the L-shaped pressing block 20 to move toward the side close to the extrusion block 21, and then the L-shaped pressing block 20 presses the extrusion block 21, and the extrusion block 21 drives the rotating plate 19 to rotate, and the rotating plate 19 drives the temporary storage ring 17 to rotate. At this time, the two temporary storage rings 17 will rotate away from each other, and then the packaged fish fillets will fall along the gap between the two temporary storage rings 17 to the top of the recovery belt 5 below, so as to realize the recycling of the packaged fish fillets.

[0049] The frame 16 is provided with a rotating groove adapted to the rotating plate 19 inside, and a torsion spring 22 is arranged in the rotating groove, and the torsion spring 22 is sleeved on the surface of the rotating rod at the end of the rotating plate 19; when working, when the rotating plate 19 rotates, the rotating plate 19 will simultaneously drive the rotating rod at its end to rotate, and drive the torsion spring 22 to contract. When the packaged fish fillets fall, the two electric push rods 18 are controlled to approach each other, so that the L-shaped pressing block 20 is away from the extrusion block 21, and then the elastic force of the torsion spring 22 is restored, and the two temporary storage rings 17 are restored to the initial position, so as to facilitate the subsequent continued packaging of the fish fillets.

[0050] The recovery belt 5 is connected through an external transmission roller transmission, and the top of the temporary storage ring 17 is connected to the external packaging bag conveyor line; when the packaged fish fillets fall onto the recovery belt 5 below, new packaging bags are placed inside the two restored temporary storage rings 17 through the external packaging bag conveyor line, and at this time, the fish fillets after the material is divided just fall from the top of the conveyor belt 4, so that continuous packaging of the fish fillets can be achieved; it should be noted that the external packaging bag conveyor line conveys the new packaging bag in a prior art manner, which will not be described in detail in the embodiments of the present invention.

[0051] Working principle: in the initial state, the piles of fish fillets are located inside the feeding tray 2. The feeding tray 2 can feed the fish fillets one by one onto the inclined dividing plate 3. Then, the dividing mechanism can screen the fish fillets according to a constant weight. Subsequently, the fish fillets of constant weight are conveyed to the inside of the packaging mechanism by the conveyor belt 4. Finally, the packaged fish fillets can be recovered by the recovery belt 5, which is convenient for subsequent operations. The dividing mechanism can ensure that the weight of the fish fillets packaged each time is constant, ensuring that they are packaged in subsequent packaging bags. Moreover, the dividing mechanism can automatically package and recycle the fish fillets, saving the labor of the staff. When the piles of fish fillets are placed above the feeding tray 2, the feeding tray 2 is controlled to rotate by a motor. Since the bottom ends of the annular plate 6 and the annular baffle 7 are in contact with the upper surface of the feeding tray 2 but not fixedly connected, when the feeding tray 2 rotates, the annular plate 6 and the annular baffle 7 will play a certain limiting role on the fish fillets, and enter the smaller gap between the annular plate 6 and the annular baffle 7 along the side wall of the annular baffle 7. See attached Figure 2 As shown, the fish fillets will then fall along the notch on the surface of the annular plate 6 to the inclined surface of the inclined material dividing plate 3 below. This design can facilitate the release of the fish fillets one by one, which is conducive to the subsequent screening and packaging of the fish fillets according to a constant weight, and the operation is more convenient;

[0052] In the initial state, the positions of the shielding plate 1 9 and the shielding plate 2 10 are as shown in the attached figure. Figure 4 and Figure 5 As shown, when the feeding plate 2 drops the fish fillets uniformly onto the inclined surface of the inclined material distribution plate 3, the fish fillets will slide down to the side of the shielding plate 2 10 in an array. When the transmission wheel 401 is rotating, the transmission wheel 401 will drive the shielding plate 2 10 and the shielding plate 1 9 to move up to the position shown in the attached figure through the driving unit. Figure 6 As shown in the figure, at this time, the shielding plate 10 no longer blocks the fish fillet, and the shielding plate 19 blocks the fish fillet on the other side, so the fish fillet between the shielding plate 10 and the shielding plate 19 will fall onto the conveyor belt 4; then, through the action of the driving unit, the shielding plate 19 and the shielding plate 10 can be restored to the state shown in the figure. Figure 4 and Figure 5 Initial position, so that the shielding plate 1 9 and the shielding plate 2 10 are intermittently pushed, that is, the amount of fish fillets falling each time is the amount between the shielding plate 1 9 and the shielding plate 2 10, so the amount of fish fillets conveyed each time is constant, that is, the weight is constant, which is convenient for subsequent packaging of fish fillets of constant weight;

[0053] When the transmission wheel 401 drives the conveyor belt 4 to rotate, the transmission wheel 401 drives the rotating shaft 11 to rotate through the belt 402, and the rotating shaft 11 drives the cam 12 on its surface to rotate. During the rotation of the cam 12, its convex surface contacts and squeezes the arc surface of the arc block 14, so that the arc block 14 drives the support frame 13, the shielding plate 1 9 and the shielding plate 2 10 to move up to the attached Figure 6 As shown, the fish fillets will slide onto the surface of the conveyor belt 4 as described above, and when the convex surface of the cam 12 is separated from the arc block 14, under the action of gravity, the baffle plate 1 9 and the baffle plate 2 10 will return to their initial positions, thereby facilitating the subsequent constant screening of the fish fillets. Such a design can ensure that the number and weight of the fish fillets falling between the baffle plate 1 9 and the baffle plate 2 10 are the same each time, and can be just packaged in the subsequent packaging bags; when the support frame 13 moves, the support frame 13 will move on the side wall of the limiting plate 15 through the sliding rod, and the sliding rod will drive the spring in contact with it to stretch. When the convex surface of the cam 12 is separated from the arc block 14, under the gravity of the support frame 13, the elastic force of the spring and the limiting of the sliding rod by the limiting plate 15, the baffle plate 1 9 and the baffle plate 2 10 can be restored to their initial positions, thereby facilitating the constant weight conveying of the fish fillets;

[0054] When the fish fillet of constant weight falls into the packaging bag, the two electric push rods 18 are controlled to move so that the telescopic ends of the two electric push rods 18 drive the heat sealing strips 181 to approach each other, and then the two heat sealing strips 181 will seal the opening of the packaging bag, and then under the action of the recycling mechanism, the heat-sealed packaging bag can be recovered and dropped above the recycling belt 5, so as to realize the function of automatic packaging of the fish fillet; when the heat sealing of the packaging bag is completed, the telescopic ends of the two electric push rods 18 are controlled to move away from each other so that the two heat sealing strips 181 move away from each other, and the two electric push rods 18 will drive the L-shaped pressing block 20 to move toward the side close to the extrusion block 21, and then the L-shaped pressing block 20 presses the extrusion block 21, and the extrusion block 21 drives the rotating plate 19 to rotate, and the rotating plate 19 drives the temporary storage ring 17 to rotate, and at this time, the two temporary storage rings 17 will rotate in the direction of moving away from each other, and then the packaged fish fillet will fall along the gap between the two temporary storage rings 17 to the top of the recycling belt 5 below, so as to realize the recycling of the packaged fish fillet.

[0055] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
