DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] The purpose of the present invention is to provide a modular mesh belt and a conveying system to solve the problems existing in the above-mentioned related technologies, so that the modular mesh belt can adapt to various conveying conditions, improve the working efficiency of the modular mesh belt, and enhance the adaptability of the modular mesh belt and the conveying system.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1

[0042] This embodiment provides a modular mesh belt, please refer to Figures 1-11, including a supporting unit and a conveying unit, the supporting unit includes multiple groups of mesh belt modules 1, and adjacent mesh belt modules 1 are detachably connected; the conveying unit includes conveying rollers 2, which are rotatably connected to the mesh belt modules 1, and the conveying rollers 2 are protruding from the mesh belt modules 1. The circumferential surface of the conveying rollers 2 can contact the conveyed items, and the conveying rollers 2 can drive the conveyed items to move; there are many types of conveying rollers 2, and the conveying rollers 2 are detachably connected to the mesh belt modules 1.

[0043] The modular mesh belt of the present invention, the support unit provides stable support for the conveying unit, and the two cooperate to drive the conveyed items to move to achieve the purpose of conveying. The support unit of the present invention includes multiple groups of mesh belt modules 1, and adjacent mesh belt modules 1 are detachably connected. The mesh belt modules 1 can be assembled according to different conveying conditions and conveying requirements, so as to adjust the structure and specifications of the support unit; at the same time, there are many types of conveying rollers 2 of the conveying unit, and different conveying rollers 2 can be selected according to different conveying conditions and conveying requirements, or different conveying rollers 2 can be selected in different conveying sections, further improving the adaptability of the modular mesh belt to various conveying conditions, thereby improving conveying efficiency, solving various problems that arise when conveying different items, ensuring conveying quality, and extending the service life of the modular mesh belt. It needs to be explained here that the modular mesh belt also includes a frame, a drive unit, etc. to drive the conveying unit to move. Setting the drive unit and selecting a suitable driver are common means for those skilled in the art, and will not be repeated here.

[0044] Specifically, the conveying roller 2 includes a first roller 3, and the first roller 3 includes a first pin 301, a first bushing 302 and a first lining 303. The first pin 301 is connected to the mesh belt module 1, and the first pin 301 is a cylindrical structure. The first bushing 302 can be rotatably mounted on the outside of the first pin 301. The first lining 303 is a tubular structure. The first lining 303 can be rotatably mounted on the first bushing 302 and the outside of the first pin 301. There are two groups of first bushings 302, and the first bushings 302 are rotatably connected to the axial ends of the first lining 303 respectively. A first protective layer 304 is provided on the outer peripheral surface of the first lining 303, and the first protective layer 304 is made of elastic material. In the first roller 3 of the present invention, the first bushing 302 and the first pin 301 form a first-level rotation mechanism, while the first bushing 302 and the first inner liner 303 form a second-level rotation mechanism. When conveying items similar to woven bags, during the conveying process, loose threads from the woven bags will gradually become entangled in the gap between the first bushing 302 and the mesh belt module 1 as the first roller 3 rotates, until the rotation of the first bushing 302 is blocked. At this time, the first inner liner 303 can still rotate relative to the first bushing 302, and the second-level rotation mechanism can still function, allowing the modular mesh belt and conveying system to operate normally, adapting to the conveyance of items such as woven mesh bags that are prone to tangling threads, and improving the adaptability of the modular mesh belt. If the tangled threads continue to increase and block the movement of the second-level rotation mechanism, tools such as diagonal pliers can be used to remove the tangled threads. The gap between the first bushing 302 and the mesh belt module 1 is appropriately set to allow tools to reach in and remove the tangled threads. A first protective layer 304 is provided on the outer peripheral surface of the first inner lining 303 of the first roller 3 of the present invention. The first protective layer 304 is made of an elastic material. The first protective layer 304 can be made of materials such as rubber to effectively protect the conveyed items and improve the conveying quality. In actual applications, the first protective layer 304 can also be made of other elastic materials to achieve the purpose of protecting different types of conveyed items.

[0045] In this specific embodiment, the axial cross-section of the first bushing 302 is T-shaped, the first inner liner 303 has a mounting groove adapted to the first bushing 302, the larger diameter end of the first bushing 302 is rotatably disposed in the mounting groove, and a gap is provided between the outer peripheral surface of the larger diameter end of the first bushing 302 and the side wall of the mounting groove. The first bushing 302 is configured as a stepped structure so that the wire wound in the gap between the first bushing 302 and the mesh belt module 1 first contacts the axial end surface of the larger diameter portion of the first bushing 302, thereby preventing the wire wound in the gap between the first bushing 302 and the mesh belt module 1 from contacting the axial end surface of the first inner liner 303 from the beginning and affecting the rotation of the first inner liner 303, thereby improving the working reliability of the two-layer rotation mechanism of the first roller 3, enhancing the anti-winding ability of the first roller 3, and improving the adaptability of the conveying roller 2.

[0046] In other specific embodiments that can be implemented by the present invention, the first roller 3 also includes a first spacer 305. The first spacer 305 is arranged inside the first liner 303. The two first bushings 302 are respectively arranged at the axial ends of the first spacer 305. The first spacer 305 can support the two first bushings 302 so that there is a gap between the first bushings 302 and the first liner 303, and the gap is uniform. During the modular mesh belt conveying process, when there are many wires wrapped around the gap between the first bushing 302 and the mesh belt module 1, the first bushing 302 will press against the side of the first liner 303, reducing the smoothness of the operation of the first roller 3 and affecting the conveying efficiency. The first spacer 305 is provided to maintain the gap between the first bushing 302 and the first liner 303, ensuring the smoothness of the rotation of the first roller 3, which is conducive to further improving the structural stability and reliability of the first roller 3. In this specific embodiment, the gap between the first bushing 302 and the first inner liner 303 is 0.5 mm. In actual applications, the gap between the first bushing 302 and the first inner liner 303 can be adjusted according to specific working conditions.

[0047] Among them, the first spacer 305 is a tubular structure, and the first spacer 305 is plugged into the first bushing 302, which facilitates the disassembly and assembly of the first roller 3, ensures that the first spacer 305 can provide stable support for the first bushing 302, and prevents the first spacer 305 from affecting the normal rotation of the first lining 303 and the first bushing 302.

[0048] More specifically, the conveying roller 2 includes a second roller 4, the second roller 4 includes a second pin 401, a second bushing 402 and a second lining 403, the second pin 401 is connected to the mesh belt module 1, the second pin 401 is a cylindrical structure, the second bushing 402 is rotatably mounted on the outside of the second pin 401, the second lining 403 is mounted on the outside of the second pin 401 and the second bushing 402, there is a gap between the second pin 401 and the inner wall of the second lining 403, the outer peripheral surface, axial end face and inner wall of the second lining 403 in contact with the second bushing 402 are all provided with a second protective layer 404, and the second protective layer 404 is made of elastic material. The second roller 4 is provided with a second protective layer 404 on the outer peripheral surface, axial end surface and inner wall in contact with the second sleeve 402 of the second lining 403, so that the second protective layer 404 is provided on the parts where the second lining 403 contacts other components, thereby achieving large-area coverage of the second protective layer 404. The second protective layer 404 is made of elastic material, which effectively reduces the operating noise of the second roller 4, further improves the adaptability of the modular mesh belt to different conveying conditions, and at the same time improves the conveying stability of the modular mesh belt, thereby extending the service life of the modular mesh belt. It should also be noted that the second roller 4 of the present invention is provided with a second sleeve 402 between the second lining 403 and the second pin 401, which can improve the rotation smoothness of the second lining 403 and the second pin 401 (the friction coefficient between the second lining 403 and the second pin 401 is greater than the friction coefficient between the second sleeve 402 and the second pin 401), and can also extend the service life of the second roller 4 (the second roller 4 will generate heat when running at high speed. The material of the second sleeve 402 is reasonably selected so that the second sleeve 402 can meet this operating condition without significantly increasing the operating noise).

[0049] At the same time, the conveying roller 2 includes a third roller 5, which includes a third pin 501 and a third lining. The third pin 501 is connected to the mesh belt module 1, and the third lining is rotatably mounted on the outside of the third pin 501. The third lining is a split structure. A third protective layer 502 is provided on the outer peripheral surface of the third lining, and the third protective layer 502 is made of elastic material. When the modular mesh belt conveys large goods, is impacted by external forces, or the conveying roller 2 is abnormally obstructed, the conveying roller 2 is first destroyed, playing a buffering role, thereby protecting the mesh belt module 1. The third lining of the third roller 5 adopts a split structure. When maintaining the damaged conveying roller 2, there is no need to disassemble the mesh belt module 1. The split third roller 5 can be installed on the conveying mesh belt, thereby realizing convenient replacement of the conveying roller 2, improving the maintenance convenience of the modular mesh belt, and helping to improve the working efficiency of the modular mesh belt and extend the service life of the modular mesh belt.

[0050] It should be explained here that the first pin 301, the second pin 401 and the third pin 501 are all fixedly connected to the mesh belt module 1. One end of the first pin 301, the second pin 401 and the third pin 501 is tightly fitted with the mesh belt module 1, and the other end has straight or reticulated knurling. The end with the knurling is interference fit with the mesh belt module 1, thereby fixing the first pin 301, the second pin 401 and the third pin 501 to the mesh belt module 1. In actual applications, the first pin 301, the second pin 401 and the third pin 501 can also be connected to the mesh belt module 1 using other connection methods.

[0051] In this specific embodiment, the third inner liner includes two inner liner blocks 503, which are connected by snapping. This convenient snapping connection facilitates assembly and disassembly of the third roller 5. It should also be noted that in this specific embodiment, the inner liner block 503 includes two liner segments 504, each of which is a semi-cylindrical structure. The radial cross-sections of the two liner segments 504 are connected, and the angle between the axial cross-sections of the two liner segments 504 is 90°. This ensures that the two inner liner blocks 503 can be smoothly snapped together while improving the structural strength of the inner liner block 503. The end of the liner segment 504 away from the other liner segment 504 has a rotation groove that is compatible with the third pin 501. When the third pin 501 of the inner liner block 503 is assembled, the staggered arrangement of the two liner segments 504 of the inner liner block 503 further improves assembly convenience. In practical applications, the circumferential surfaces of the two inner lining blocks 503 of the third roller 5 can be provided with a third protective layer 502 according to actual working conditions, thereby improving the flexibility and adaptability of the third roller 5 while meeting various conveying requirements.

[0052] The conveying roller 2 of the present invention includes a first roller 3, a second roller 4 and a third roller 5. In actual application, one or several conveying rollers 2 of different types can be selected according to different conveying conditions and conveying requirements, and suitable types of conveying rollers 2 can be selected in different conveying sections to improve the adaptability of the modular mesh belt to various conveying conditions, improve the conveying efficiency, and extend the service life of the modular mesh belt.

[0053] It should also be noted here that in actual application, the ends of the first pin 301, the second pin 401 and the third pin 501 can be provided with knurling patterns to ensure the firm connection between the first roller 3, the second roller 4 and the third roller 5 and the mesh belt module 1.

[0054] Furthermore, the mesh belt module 1 of the present invention has mesh belt teeth on both sides perpendicular to the rotation axis of the conveyor roller 2, and connecting tooth grooves 6 adapted to the mesh belt teeth are formed between adjacent mesh belt teeth, and the mesh belt teeth have through holes that allow connecting pins to pass through; when adjacent mesh belt modules 1 are connected, the mesh belt teeth extend into the connecting tooth grooves 6 of the adjacent mesh belt modules 1 and are connected by connecting pins; adjacent mesh belt modules 1 use mesh belt teeth to insert into the connecting tooth grooves 6, and use connecting pins to pass through the through holes of the mesh belt teeth of the adjacent mesh belt modules 1 to achieve connection, and the disassembly and assembly operations are convenient, while improving the flexibility of the support unit structure, the construction efficiency of the support unit is improved. When the conveyor unit needs to be repaired, only the mesh belt module 1 in the area that needs to be repaired can be removed, thereby improving the convenience of use and maintenance of the modular mesh belt. It should be explained here that when the third roller 5 needs to be repaired, the mesh belt module 1 does not need to be removed, and the third roller 5 can be directly replaced.

[0055] In this embodiment, the mesh belt teeth include first mesh belt teeth 7 and second mesh belt teeth 8. The first and second mesh belt teeth 7 and 8 have different thicknesses, and the connecting tooth grooves 6 are compatible with the first and second mesh belt teeth 7 and 8. The present invention utilizes first and second mesh belt teeth 7 and 8 with different thicknesses, with the first mesh belt teeth 7 being thicker than the second mesh belt teeth 8. Accordingly, the connecting tooth grooves 6 formed by adjacent mesh belt teeth are also of two different sizes to match the first and second mesh belt teeth 7 and 8. The different sizes of the mesh belt teeth ensure that the mesh belt module 1 is assembled in a regular manner, providing a foolproof method and preventing misalignment of the mesh belt module 1, which could affect the structural reliability of the support unit. In this embodiment, the thicker first mesh belt teeth 7 are located at the thick ribs of the mesh belt module 1, while the thinner second mesh belt teeth 8 can be evenly distributed throughout the remaining locations of the mesh belt module 1 or arranged according to a specific pattern to further enhance the flexibility and adaptability of the support unit. It should be explained here that the mesh belt module 1 has thick ribs and thin ribs, which is common knowledge among those skilled in the art and will not be described in detail here.

[0056] In this specific embodiment, the mesh belt module 1 includes an intermediate mesh belt 9 and an end mesh belt 10. The intermediate mesh belt 9 is arranged between the two end mesh belts 10 in a direction perpendicular to the rotation axis of the conveyor roller 2. The specifications of the intermediate mesh belt 9 can be set to a variety to meet the construction of support units of different types and specifications. The end of the end mesh belt 10 away from the intermediate mesh belt 9 has a connecting hole 11, so that the mesh belt module 1 is connected to other structures of the module mesh belt using the connecting hole 11. In other specific embodiments that can be implemented by the present invention, the end of the end mesh belt 10 away from the intermediate mesh belt 9 also has a transition slope 12. In the direction gradually away from the intermediate mesh belt 9, the transition slope 12 is inclined from the top surface of the end mesh belt 10 to the bottom surface of the end mesh belt 10, thereby reducing the conveying resistance of the module mesh belt. For example, when the module mesh belt is used in a sorting system, the inclined transition slope 12 is helpful in reducing the sorting resistance on the side of the module mesh belt.

[0057] Example 2

[0058] This embodiment provides a modular mesh belt, in which the length of the roller is increased from 41.3 mm in the prior art to 59.5 mm, an increase of 18.2 mm, and the pitch of the modular mesh belt is increased from 63.5 mm in the prior art to 80.8 mm, an increase of 17.3 mm.

[0059] For example, when transporting a box of 300 mm in length, the contact area between the modular mesh belt of this embodiment and the box is increased by about 10.2% compared with the small pitch mesh belt in the prior art. Figure 11 , the upper part of the figure is the modular mesh belt with an increased pitch of this embodiment, and the lower part is the mesh belt with a smaller pitch in the prior art.

[0060] The length of the conveyor roller 2 in this embodiment is lengthened, and the pitch of the modular mesh belt is correspondingly increased, so that when the modular mesh belt transports the same items, the conveyed items can be supported by more conveyor rollers 2, increasing the contact points, which is beneficial to improving the sorting, separation and merging efficiency of the modular mesh belt.

[0061] In other embodiments of the present invention, the pitch of the modular mesh belt and the length of the conveyor rollers can be adjusted according to actual working conditions, thereby enhancing the support efficiency of conveyed items while also improving the flexibility and adaptability of the modular mesh belt. It should be noted that in one embodiment, the pitch of the modular mesh belt is fixed, and the lengths of various types of conveyor rollers are adapted to the pitch of the modular mesh belt.

[0062] The other structures of the modular mesh belt of this embodiment are the same as those of the first embodiment and will not be described again here.

[0063] Example 3

[0064] This embodiment provides a conveying system, including the modular mesh belt of embodiment one or embodiment two.

[0065] In actual applications, the conveying system can be assembled according to actual conveying and sorting requirements. While using modular mesh belts, friction rollers, support bars and other structures can also be set to meet various conveying conditions.

[0066] The modular mesh belt of the present invention increases the pitch of the modular mesh belt, and the mesh belt module 1 is provided with an anti-fool structure, thereby effectively improving the assembly efficiency of the modular mesh belt, and at the same time improving the sorting, channeling and merging performance of the conveyed goods during operation; the modular mesh belt of the present invention can be combined with different types of conveying rollers 2 and mesh belt modules 1 according to different conveying conditions to form modular modular mesh belts with different performances to meet the needs of different industries and working conditions, greatly improving the flexible adaptability of the modular mesh belt, and is conducive to improving the conveying efficiency of the modular mesh belt, solving various problems arising when conveying different items, ensuring the conveying quality, and extending the service life of the modular mesh belt.

[0067] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
