Description

Technical Field

[0001] This utility model relates to the field of transfer and transportation device technology, specifically to a lifting roller with lifting and transferring platform function, a transfer machine base equipped with the lifting roller, and a transfer machine equipped with the base. Background Technology

[0002] A transfer machine is a common transport device in a transmission system. After passing through the transfer machine, the original direction of travel of the relevant items can be changed. In this way, the transfer machine can realize the connection between multiple conveyor lines.

[0003] For example, patent application number 202322056993.1 discloses an ultra-long conveyor fork embedded transfer machine, which includes a frame, a conveying mechanism and a transfer mechanism disposed within the frame. The conveying mechanism includes multiple spaced conveying rollers and a conveying roller drive assembly. The transfer mechanism includes a lifting assembly, multiple conveying forks disposed on the lifting assembly, and a conveying fork drive assembly. The multiple conveying forks are respectively disposed at the intervals of the conveying rollers. At least one end of the conveying fork extends out of the frame, and a transition plate is provided on the frame at the extended end of the conveying fork. The transition plate is provided with a conveying fork avoidance groove.

[0004] In use, the aforementioned transfer machine can be installed on the first conveyor line and connected to the frame of the adjacent and parallel second conveyor line via a transition plate. When the item is conveyed to the conveyor roller of this transfer machine via the first conveyor line, the lifting component moves to lift the conveyor fork, which in turn lifts the item. Subsequently, the conveyor fork moves to transfer the item to the second conveyor line, thereby realizing the transfer of items between different conveyor lines.

[0005] Most of the aforementioned transfer machines, as well as those commonly available on the market, employ cams and bearings to form their lifting components. However, long-term use has revealed that when these lifting components raise and lower the conveyor forks and other transport components, the lifting arc on the outer wall of the cam, composed of multiple interlocking arcs, can result in an uneven lifting trajectory. Consequently, when the lifting component of the transfer machine is operating at its height, it can easily cause vibrations in the transport components above it. This can lead to positional shifts or even tipping over of high-center-of-gravity, heavy, or high-value items during transport, ultimately resulting in damage or other accidents. Utility Model Content

[0006] One of the purposes of this invention is to provide a lifting roller with a smoother lifting trajectory, thereby enabling the object to be lifted to rise and fall smoothly.

[0007] The second objective of this utility model is to provide a transfer machine base equipped with the aforementioned lifting rollers, which enables the smooth lifting and lowering of the transmission components.

[0008] The third objective of this utility model is to provide a transfer machine equipped with the aforementioned base for a transfer machine, which, while having a transfer function, ensures the smooth lifting and lowering of the transported items.

[0009] This utility model is achieved through the following technical solution: In a first aspect, the present invention provides a lifting roller, comprising: a main roller and a plurality of lifting sections mounted on the main roller; each set of lifting sections includes at least two sets of eccentric wheels, the plurality of eccentric wheels being fitted onto the main roller through drive through holes, and each set of eccentric wheels having an eccentric top that is furthest away from the main roller; wherein, a first included angle is formed between the eccentric shafts of at least two sets of eccentric wheels, such that at least two sets of lifting points formed by the eccentric tops of the eccentric wheels are formed within the same set of lifting sections, and a lifting drop is formed between the plurality of sets of lifting points.

[0010] The eccentric wheel has a geometric center formed according to its outer contour; and since it is mounted on the main roller through a drive through hole, a rotation center is formed within the drive through hole as it rotates with the main roller. The axis formed by connecting the rotation center and the geometric center is the eccentric shaft. Because the geometric center and the rotation center of the eccentric wheel do not coincide, the distance between the outer wall surface of the eccentric wheel and the rotation center varies at different points. An eccentric top is formed on the outer wall surface at the intersection point extending outward from the rotation center along the eccentric shaft to the outer wall surface of the eccentric wheel. This eccentric top is the part of the outer wall surface with the greatest distance from the rotation center.

[0011] When the eccentric wheel is installed on the main roller through the drive through hole, the distance between its outer wall surface and the axis of the main roller varies at different points, with the top of the eccentric wheel being the point farthest from the main roller. Since the outer wall surface of the eccentric wheel is used to contact the component being lifted, when the main roller drives the eccentric wheel to rotate, the distance between the axis of the component being lifted and the axis of the main roller also changes accordingly, thereby realizing the lifting and lowering of the component relative to the main roller.

[0012] The eccentric top of a single set of eccentric wheels can independently form a lifting point; if the eccentric shafts of multiple sets of eccentric wheels coincide, the eccentric tops of the multiple sets of eccentric wheels together form a lifting point. When the eccentric shaft is vertical and the eccentric top is above the main roller, the lifting component contacts the eccentric top and is then lifted to its highest height. At this time, the lifting point in the lifting section formed by the eccentric tops of the eccentric wheels plays its supporting role for the lifting component, which is then lifted to its highest point by the lifting component. In this invention, at least two sets of eccentric wheels have a first included angle between their eccentric shafts. Therefore, when the lifting point formed by one set of eccentric wheels, or multiple sets of eccentric wheels with overlapping eccentric shafts, plays its lifting role, the lifting points formed by the remaining eccentric wheels will be lower than the lifting section that plays its lifting role, thus creating a lifting height difference between the two.

[0013] In this invention, the outer wall surface of the eccentric wheel used for the lifting roller has a relatively complete curvature, which ensures that the lifting trajectory is a complete arc shape when it is lifting, and the transition of the arc surface is smoother, further ensuring that the lifting process of the lifted component is more stable.

[0014] On the other hand, the same lifting section of the lifting roller contains at least two lifting points, which can realize the lifting and lowering of multiple sets of lifting components separately, and ensure the succession of the supporting function of the lifting components. Specifically, when the lifting roller is used in the transfer machine to control the lifting and lowering of two sets of transmission components, after the main roller rotates, one set of transmission components will descend, while the other set of transmission components will rise synchronously due to the lifting of the eccentric wheel. This allows the items being transferred on the transfer machine to be quickly lifted and raised again by the rising other set of transmission components after a slight descent with one set of transmission components, thereby reducing the total lifting height of the items during the transfer operation.

[0015] As a further improvement of this utility model, a friction-reducing kit is provided on the outside of the eccentric wheel. When the main roller drives the eccentric wheel to rotate, thereby driving the lifting component to rise and fall, the lifting component will slide relative to the outer surface of the eccentric wheel, thus generating friction. The friction-reducing kit can reduce the magnitude of the friction between the two, thereby reducing the friction force that the main roller needs to overcome when rotating, and also reducing the power consumption. This friction-reducing kit can be a component or kit that converts sliding friction into rolling friction, such as a movable bushing fitted around the eccentric wheel or a rolling bearing fitted around the eccentric wheel.

[0016] As a further improvement of this utility model, the friction-reducing kit includes a rotating ring block fitted outside the eccentric wheel, and a plurality of friction-reducing balls embedded between the rotating ring block and the outer wall surface of the eccentric wheel.

[0017] As a further improvement of this utility model, it also includes a transmission part disposed on the main roller, the transmission part including at least a mounting base fitted on the main roller. After the transmission part is provided, when using multiple sets of lifting rollers, only one set of lifting rollers can be set as the driving roller, and the remaining rollers are connected through the transmission part to ensure the consistency of operating parameters such as rotation angle. For example, the transmission part may include a rigid transmission rod, the two ends of which are movably connected to the mounting base, so that when the driving roller rotates, it drives the remaining main rollers to rotate synchronously through the transmission rod; the transmission part may also include a transmission gear and a transmission ring belt fitted outside the transmission gear, so that when the driving roller rotates, it drives the remaining main rollers to rotate synchronously through the meshing of the teeth between the transmission gear and the transmission ring belt.

[0018] As a further improvement of this utility model, the transmission part also includes a transmission gear fitted on the mounting base.

[0019] Secondly, this utility model provides a base for a transfer machine, which includes a main frame and several sets of any of the above-mentioned lifting rollers disposed on the main frame.

[0020] As a further improvement of this utility model, it also includes a transmission ring belt adapted to the transmission gears. The transmission ring belt is fitted onto several sets of transmission gears to drive several sets of lifting rollers to rotate synchronously.

[0021] As a further improvement of this utility model, a tensioning part is also included for tensioning the transmission ring belt. The tensioning part can be any component or kit that can ensure the meshing of the toothed blocks on the transmission ring belt with the toothed blocks on the transmission gear to avoid accidents such as tooth skipping. For example, the tensioning part can be a tensioning wheel structure that fits tightly against the transmission ring belt.

[0022] As a further improvement of this utility model, the tensioning part includes a telescopic kit, one end of which is fixedly connected to the main frame and the other end is fixedly connected to the end of the main roller, so as to control the spacing between two adjacent sets of lifting rollers.

[0023] Thirdly, this utility model provides a transfer machine, which includes any of the above-mentioned transfer machine bases, and a first transmission module and a second transmission module installed above the transfer machine base; the first transmission module has a working channel that allows the transmission surface of the second transmission module to rise and fall; a second included angle is formed between the transmission directions of the first transmission module and the second transmission module; a first docking portion is formed at the bottom of the first transmission module, and a second docking portion is formed at the bottom of the second transmission module; the first docking portion and the second docking portion are respectively connected to eccentric wheels with different lifting points on the lifting roller, so that the lifting portion drives the first transmission module and the second transmission module to rise and fall respectively through different eccentric wheels.

[0024] The beneficial effects of this utility model include: (1) The lifting roller utilizes the change in the distance between the outer wall of the eccentric wheel and the rotation center when the main roller rotates to realize the lifting function of the lifting component. The outer wall of the eccentric wheel is a complete arc, which ensures the smoothness of its lifting trajectory and makes the lifting and lowering process of the lifting component more stable. When performing high-frequency and high-speed lifting operations, the vibration amplitude is reduced.

[0025] (2) The same set of lifting parts of the lifting roller contains at least two sets of lifting points with lifting drop, which allows the lifting roller to simultaneously lift and lower the two sets of lifting components when rotating. When the lifting roller is used in the transfer machine, it can drive the other set of transmission components to rise while one set of transmission components is descending. This allows the items being transported on the transmission components to be supported by the other set of transmission components after a slight descent and to be lifted again as they are lifted, reducing the overall height variation of the items being transported. This reduces the probability of the center shift and overturning when the heavy, high-center-of-gravity items are transported.

[0026] (3) In the base of the transfer machine, a transmission part consisting of transmission gears and transmission belts can be used to ensure that the rotation angles of multiple lifting rollers are consistent. This ensures that during the lifting operation, the distance between the point of contact between the eccentric wheel of the multiple lifting rollers and the lifting component and the main roller is consistent, that is, the height supported by the lifting rollers on the lifting component is consistent. When the lifting component is a transmission component, it can ensure that the transmission surface of the transmission component is in a horizontal state to avoid displacement or even overturning of the items being transmitted on it.

[0027] (4) Regarding the base of the transfer machine, the existing technology commonly uses a rigid connecting rod structure to realize the transmission between two adjacent lifting rollers. On the one hand, during the high-efficiency operation of the transfer machine, it is necessary to maintain the rapid response of the lifting rollers. During the rapid rotation of the lifting rollers, it is easy for the relative movement between the connecting rod and the lifting rollers to be too fast, resulting in misalignment, which is usually called "overshoot". At this time, it is easy for the two ends of the connecting rod placed between the two sets of lifting rollers to be jammed with the two sets of lifting rollers respectively, thus causing the lifting rollers to be unable to rotate synchronously, requiring manual intervention for maintenance. On the other hand, in the connecting rod... During the synchronous rotation of the connecting rod and the two adjacent sets of lifting rollers, the connecting rod itself will undergo vertical displacement. This usually requires an operating space in the base to accommodate the connecting rod, resulting in a relatively high overall height of the transfer machine base, which is not conducive to its use in low-height spaces. In this utility model, the transmission part composed of transmission gears and transmission belts in the transfer machine base avoids the situation where the two adjacent sets of lifting rollers are jammed during the efficient operation of the transfer machine. At the same time, the operating space in the base can be saved, thereby reducing the overall height of the transfer machine base.

[0028] (5) In the transfer machine, the base contains the above-mentioned lifting roller, and the eccentric wheel on it can realize the lifting function of the first transmission module and the second transmission module respectively; when the distance between the two sets of lifting points in the lifting part and the main roller is the same, it can be ensured that when the first transmission module or the second transmission module is lifted to the highest height, the relative height that the two can reach on the transfer machine is the same, thereby ensuring that the transmission surface height of the conveyor line connected to the first transmission module or the second transmission module can be kept consistent, and thus ensuring that the transmission surface height of the whole transmission system can be kept consistent, so that the overall transmission system can be more suitable for the transmission of heavy, high-center-of-gravity items, etc. Attached Figure Description

[0030] Among them Figure 7 In order to demonstrate the working channel structure, some structures such as the transmission belt in the second transmission module are hidden; Figure 8 In order to demonstrate the structures such as the first and second docking parts, the side plates and other structures of the transfer machine base are concealed.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Example

[0033] This embodiment provides a lifting roller A, such as Figure 1 As shown, the structure includes a main roller 1 and two sets of lifting sections 2 located at both ends of the main roller 1. Each lifting section 2 includes two sets of eccentric wheels 201, both sets of eccentric wheels 201 being fitted onto the main roller 1 through drive through holes; a first included angle α is formed between the eccentric shafts 201-2 on the two sets of eccentric wheels 201, which in this embodiment is 180°, thus achieving the separation of the two sets of eccentric tops 201. Under this structure, a set of lifting points 2-1 is formed by the eccentric tops 201 on a single set of eccentric wheels 201, resulting in a total of two sets of lifting points 2-1 in the lifting section 2.

[0034] In this design, two sets of eccentric wheels 201 contact different components being lifted via their respective outer walls, thus providing support for the components. The distance between the contact point on the outer wall of the eccentric wheel 201 and the main roller 1 determines the height of the lifted component. The eccentric top 201-1 on the eccentric wheel 201 represents the point with the greatest distance between its outer wall and the main roller. When a first included angle α is formed between the eccentric shafts 201-2 on the two sets of eccentric wheels 201, ensuring that the eccentric top 201-1 of one set of eccentric wheels is at its highest point supporting the lifted component, the other set of eccentric wheels 201 will not support the other lifted component via its eccentric top 201-1. This ensures a difference in the distance between each set of lifted components and the main roller 1, resulting in a height difference between the two sets of lifted components.

[0035] Preferably, in this embodiment, a friction-reducing kit 202 is provided outside the eccentric wheel 201. More preferably, such as... Figure 2As shown, the friction-reducing kit 202 includes a rotating ring block 202-1 fitted around the eccentric wheel 201, and multiple friction-reducing balls 202-2 embedded between the rotating ring block 202-1 and the outer wall of the eccentric wheel 201. With this structure, when the main roller 1 drives the eccentric wheel 201 to rotate, the sliding friction that would normally occur between the outer wall of the eccentric wheel 201 and the object being lifted is transformed into rolling friction. This reduces the amount of friction that the lifting roller A needs to overcome during lifting operations, thereby reducing the power consumption required for lifting operations. It also reduces the occurrence of situations where the lifting roller A is obstructed due to friction, causing the lifting operation to stall, and then rapidly resumes the lifting operation, resulting in significant vibration of the lifted component.

[0036] Preferably, the lifting roller A further includes a transmission part 3 disposed on the main roller 1, and the transmission part 3 includes at least a mounting base fitted onto the main roller 1. This mounting base can be a pre-reserved area for mounting the transmission part 3, or a pre-reserved structure such as a mounting through hole to facilitate the installation of other components of the transmission part 3. More preferably, in this embodiment, the mounting base is a pre-reserved area disposed at both ends of the main roller 1, such as... Figure 1 As shown, the transmission unit 3 also includes a transmission gear 301 fitted onto the mounting base, i.e., the preset area. After the transmission unit 3 is provided, multiple sets of lifting rollers A can rotate synchronously through the transmission unit 3, thereby facilitating multiple sets of lifting rollers A to jointly serve the same lifted component.

[0037] In the lifting roller A structure of this embodiment, when changing the height relationship between the two sets of lifting components, the lifting roller A can rotate continuously in either clockwise or counterclockwise direction without being driven to perform reciprocating motion in the clockwise or counterclockwise direction. Furthermore, when using the transmission unit 3 or similar components to achieve the coordinated operation of multiple sets of lifting rollers A, the operation mode of the lifting roller A in this embodiment can reduce wear and tear on the transmission unit 3 and similar components during long-term operation. Example

[0038] This embodiment provides a lifting roller A, which differs from that in Embodiment 1 in that, in this embodiment, a lifting section 2 includes four sets of eccentric wheels 201, all of which are fitted onto the main roller 1 through drive through holes; and the eccentric shafts 201-2 of each pair of eccentric wheels 201 overlap to form two sets of eccentric wheels. Figure 3 As shown, a first included angle α is formed between the eccentric shafts 201-2 of the two sets of eccentric wheel sets. In this embodiment, the first included angle α is 120°.

[0039] In this structure, the two sets of eccentric wheels 201 that overlap on the eccentric shaft 201-2 can jointly support a set of lifting components. The eccentric tops 201-1 of the two together form a set of lifting points 2-1. In this way, the two sets of eccentric wheels 201 can provide stronger support for the lifting components, so as to adapt to the lifting work of heavy lifting components. Example

[0040] This embodiment provides a lifting roller A, which differs from that in Embodiment 1 in that each lifting part 2 includes two sets of eccentric wheels 201, both sets of eccentric wheels 201 being fitted onto the main roller 1 through drive through holes; a first included angle α is formed between the eccentric shafts 201-2 on the two sets of eccentric wheels 201, such as... Figure 4 As shown, in this embodiment, the first included angle α is 60°, which means that the two sets of lifting points 2-1 are moved away from each other.

[0041] In the lifting roller A structure of this embodiment, only a 60° rotation of the main roller 1 is needed to achieve a change in the relative height of the two sets of objects to be lifted in the vertical direction. This driving angle is small, which allows for a faster rotational response speed of the lifting roller A. Furthermore, this results in a faster response speed for the lifting operation, and a smaller range of height position changes between the two sets of objects to be lifted before and after the change.

[0042] When used in a transfer machine, it is suitable for lifting and lowering between different transmission modules at high frequency and speed, thereby enabling rapid transfer operations. At the same time, it ensures that the lifting range of the two sets of transmission modules is reduced, which makes the change in the center of gravity of the items carried on them smaller during the transfer operation, greatly reducing the occurrence of items shifting their center of gravity. Example

[0043] This embodiment provides a base for a transfer machine, such as... Figure 5 As shown, the base of the transfer machine includes a main frame and two lifting rollers A as described in Embodiment 1, which are mounted on the main frame. After the two sets of lifting rollers A are installed on the main frame, the eccentric shafts 201-2 of the two sets of lifting rollers A on the same side, which have two sets of eccentric wheels 201, have the same orientation and initial angle. This ensures that when the transfer machine is assembled, a total of four sets of eccentric wheels 201 in the two sets of lifting rollers A can simultaneously support one transfer component, thereby ensuring the smooth operation of the lifting and lowering of the transfer component.

[0044] Preferably, such as Figures 5-6 As shown, the transfer machine base also includes a transmission ring belt 4 adapted to the transmission gear 301. Specifically, the transmission ring belt 4 is provided with toothed surfaces, and the toothed blocks on the toothed surfaces can mesh with the transmission gear 301. Therefore, after the transfer machine base is installed, as shown... Figure 5As shown, the transmission ring belt 4 on the same side is fitted onto the two sets of transmission gears 301 on the same side of the two lifting rollers A.

[0045] In this structure, only one lifting roller A needs to be installed as the driving roller in the base of the transfer machine. The other lifting roller A rotates synchronously with the transmission unit 3 and the transmission belt 4. This improves the rotational synchronization between the two sets of lifting rollers A. Compared with the method of arranging two sets of driving rollers to drive them to rotate synchronously, this structure can ensure the smooth lifting of the transmission component during long-term use and ensure that the transmission surface of the transmission component remains horizontal after long-term use. At the same time, the use of the transmission belt 4 and the transmission gear 301 to cooperate with the transmission belt 4 ensures that the user can make more precise control over the rotation angle of the lifting roller A, and thus more accurately control the lifting height of the transmission component.

[0046] Preferably, the base of the transfer machine also includes a tensioning part 5 to ensure that the transmission belt 4 meshes with the transmission gear 301 without easily causing tooth skipping or other phenomena. More preferably, such as... Figure 6 As shown, the tensioning part 5 includes a telescopic assembly 501. One end of the telescopic assembly 501 is fixedly connected to the main frame, and the other end is fixedly connected to the end of the main roller 1 to control the distance between two adjacent sets of lifting rollers A. When the distance between the two sets of lifting rollers A increases, the meshing between the transmission belt 4 and the transmission gear 301 is further strengthened. The telescopic assembly 501 can be any adjustable length component or assembly, such as a telescopic rod. Example

[0047] This embodiment provides a transfer machine, such as Figure 7 As shown, it includes the transfer machine base of Embodiment 4, and a first transmission module 6 and a second transmission module 7 mounted on the base. A second included angle β is formed between the transmission directions of the first transmission module 6 and the second transmission module 7; for example, in this embodiment, the second included angle β is 90° when viewed from a top-down perspective. Simultaneously, a working channel 601 is formed on the first transmission module 6, allowing the transmission surface of the second transmission module 7 to rise and fall, thereby ensuring that no conflict occurs when the relative height of the two changes. Furthermore, as... Figure 8 As shown, a first docking part 602 is formed at the bottom of the first transmission module 6, and a second docking part 701 is formed at the bottom of the second transmission module 7. The first docking part 602 and the second docking part 701 are respectively connected to eccentric wheels 201 with different lifting points 2-1 on the same lifting roller A, so that the same set of lifting parts 2 can drive the first transmission module 6 and the second transmission module 7 to rise and fall respectively through different eccentric wheels 201.

[0048] For example, such as Figure 7As shown, in this embodiment, the first transmission module 6 includes a first base and multiple sets of transmission rollers disposed on the first base, with a working channel 601 between adjacent sets of transmission rollers; the second transmission module 7 includes a second base and multiple sets of transmission forks disposed on the second base; after the transfer machine is assembled, the transmission forks can be raised and lowered through the working channel 601; thus, in this structure, by changing the height of the first transmission module 6 and the second transmission module 7, the transmission surfaces of the two modules can respectively contact the item, thereby driving the item to move in different transmission directions. Any other common transmission kits that can be installed on a transfer machine are compatible with this transfer machine.

[0049] For example, such as Figure 8 As shown, in this embodiment, the first docking part 602 and the second docking part 701 are respectively support plates disposed at the bottom of the first transmission module 6 and the second transmission module 7. The support plate is in contact with the outer wall surface of the eccentric wheel 201 on the lifting roller A, so that when the eccentric wheel 201 rotates with the main roller 1, the distance between the support plate and the main roller 1 changes, thereby driving the first transmission module 6 and the second transmission module 7 to rise and fall.

[0050] In this embodiment, the transfer machine, through the lifting roller A, enables the synchronous lifting and lowering of the first transmission module 6 and the second transmission module 7. For example, when the first transmission module 6 descends, the second transmission module 7 rises. This ensures that the items carried on the transfer machine, after a short descent, are supported by the rising transmission module and lifted again, reducing overall height variations. Furthermore, by selecting an eccentric wheel 201 of suitable specifications and dimensions, the height of the transmission surface formed by the first or second transmission module 7 remains constant before and after height changes, ensuring that the transmission surface heights of the two transmission lines connected by the transfer machine are consistent. In summary, when the transfer machine of this embodiment is used in the transmission system, the overall transmission surface height of the system remains consistent, reducing height variations of items during transmission. This significantly reduces the probability of item center shift and tipping when transferring heavy, high-center-of-gravity items.

[0051] Preferably, the transfer machine further includes a guide section for guiding the vertical movement of the first transfer module 6 and the second transfer module 7 to prevent horizontal offset. For example, in this embodiment, the guide section includes several guide posts disposed on the base of the transfer machine and guide holes formed on the first transfer module 6 and the second transfer module 7. The first transfer module 6 and the second transfer module 7 are fitted onto the guide posts through their respective guide holes. Any other components or kits that can guide the vertical movement of the first transfer module 6 and the second transfer module 7 are also compatible.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
