[0002] In the field of modern industrial production and logistics transportation, material conveying system plays a vital role. Traditional conveying equipment such as convex point anti-skid type mesh belt gradually exposes many limitations in practical application. First, the convex point anti-skid type mesh belt is prone to violent vibration when running at high speed due to uneven contact between convex points and materials. This vibration not only causes the position of materials to deviate during conveying, affecting conveying accuracy, but also accelerates the wear of mesh belt and related mechanical parts, reduces the service life of equipment, increases maintenance cost and downtime, and seriously affects the quality and yield of materials. For some materials with relatively fragile surfaces, such as optical lenses and precision ceramic products, the convex point structure is prone to scratching and bumping the surface of materials during contact, which seriously affects the quality and yield of materials. This is unacceptable in industries with extremely high requirements for product surface quality, such as optical instrument manufacturing and high-end ceramic processing.

[0030] Embodiment 1

[0031] Refer to Figure 1 , a flat grid type mesh belt conveying module of the embodiment, comprising:

[0032] A plurality of mesh belt links, the mesh belt link is long strip flat grid shape and is equipped with the rectangular grid of uniform distribution on the surface, the mesh belt link is equipped with the connecting flange on one side, the mesh belt link is equipped with the connecting groove corresponding with the connecting flange on the other side, the connecting flange and the connecting groove are staggered distribution along the length direction in proper order, the top of the connecting flange and the connecting groove is equipped with the positioning hole, the connecting flange of the mesh belt link is embedded in the connecting groove of the adjacent mesh belt link, and is fixed through the connecting shaft and the positioning hole, the both ends of the mesh belt link are equipped with the fixed block, and the both ends of the mesh belt link are fixed.

[0033] Specifically,

[0034] As Figure 1 Shown, first, the mesh belt link prepared is taken out one by one, and is assembled in the clean, dry environment, the connecting flange 2 of a link is aligned with the connecting groove 4 of the adjacent link and is slowly inserted, the pawl is initially aligned with the insertion port, and the insertion port on the both sides of the mesh belt body is staggered distribution along the length direction in proper order, since the length of the flange is greater than the depth of the groove, when the flange is inserted into the groove, the surface of the flange and the surface of the groove contact and form the flow guide hole 5, during the insertion process, the work fixture is positioned with the aid, the connecting flange 2 is ensured to be completely embedded in the connecting groove 4, and the pawl is accurately embedded in the insertion port, at this time, the gap between the pawl and the insertion port is controlled to be less than 0.05mm, so as to ensure the tightness and stability of the connection.

[0035] Check the connection of adjacent chain links, confirm no error, the connecting shaft 8 is inserted into the connecting flange 2 and the positioning hole 1 at the top of the connecting groove 4 in turn, the connecting shaft 8 is installed in place, and the nut is screwed on both ends. The nut is selected as high-strength hexagonal nut, the tightening torque is determined by calculation according to the diameter and material strength of the connecting shaft 8, generally 50-100 N·m, and the chain link connection is preliminarily fixed.

[0036] As shown in Figure 3 The lock washer is installed between the connecting shaft 8 and the edge of the connecting groove 4, the lock washer is sleeved on the connecting shaft 8, and the lock washer is tightly fitted with the edge of the connecting groove 4, so that there is no misalignment and no wrinkle between the metal sheets, and then the micro strain sensor is installed at the connecting groove 4 and the lock washer. A small amount of high-strength structural adhesive is applied to the specified position of the connecting groove 4, the strain gauge at the bottom of the sensor is aligned with the lock washer, and the strain gauge is pressed gently to make it tightly fit, so that the contact area between the sensor and the lock washer is greater than 80%, and then the sensor is temporarily fixed with adhesive tape or clamp. Wait for the structural adhesive to solidify to ensure the firmness and measurement accuracy of the sensor installation.

[0037] As shown in Figure 4 The fixing block 7 is installed at both ends of the mesh belt chain link, the connecting hole at the bottom end of the fixing block 7 is aligned with the corresponding position of the chain link, and is slowly inserted until the fixing block 7 is tightly fitted with the chain link. Check whether the installation position of the fixing block 7 is accurate and whether the connecting hole is aligned with the internal structure of the chain link. If there is deviation, the fixing block 7 can be slightly prised to make fine adjustment. If it is necessary to adjust the whole mesh belt, adjust the screw rod is installed outside the fixing block 7, the threaded part of the adjust screw rod is coated with appropriate amount of lubricating grease, such as lithium-based lubricating grease, and then is screwed into the threaded hole of the fixing block 7. The one end of the adjust screw rod is inserted into the mesh belt chain link, and the other end extends out of the fixing block 7, and the adjust screw rod passes through the mesh belt chain link through the positioning hole 1, so as to realize the accurate fine adjustment of the position of the single mesh belt chain link. The one end inserted into the mesh belt chain link is provided with an elastic buffer, and the elastic buffer in this embodiment is made of high-elasticity rubber. When it is necessary to adjust the position between adjacent mesh belt chain links, the operator adjusts the position by loosening the adjust screw bolt, which is installed at the end of the adjust screw rod extending out of the fixing block 7 and perpendicularly intersects with the adjust screw rod, and is connected through threads.

[0038] When the adjustment operation is performed, if a lateral deviation is found between the adjacent chain links, the operator first determines the deviation direction, and then uses a tool to loosen or tighten the adjustment bolt. For example, when the chain link deviates to the left, the adjustment bolt is loosened, so that the adjustment screw rod is slightly axially displaced to the left under the limitation of the threaded hole of the fixing block 7, and the chain link is pushed to move to the left. Conversely, if the chain link deviates to the right, the adjustment bolt is tightened, and the adjustment screw rod moves to the right to drive the chain link to return to position. Since the one end of the adjustment screw rod is inserted into the inside of the chain link and is in contact with the chain link through the elastic buffer, during the adjustment process, the elastic buffer absorbs part of the impact force generated by the adjustment, prevents the chain link from being damaged due to sudden force, and also ensures that the adjustment action is smooth and gradual, realizes the accurate adjustment of the position between the adjacent mesh belt chain links, and maintains the high precision and stability of the overall operation of the mesh belt chain.

[0039] Finally, the assembled conveying module is preliminarily debugged, the installation of the lock washer and the miniature strain sensor is observed, it is ensured that there is no looseness and displacement; the adjustment screw rod is rotated, and after the debugging is completed, the adjustment screw rod is removed. When the conveying module is connected to a power source (such as a motor driving a driving sprocket through a speed reducer) and started, the driving sprocket starts to rotate, drives the entire mesh belt chain to move forward through the friction force with the mesh belt chain links, and the materials are placed on the rectangular grid 3 of the mesh belt chain links. Due to the uniform distribution and reasonable size design of the grid, the materials can be stably supported, avoiding shaking, accumulation or sliding during the conveying process. In high-speed or heavy-load conveying, the reinforcing ribs in the chain links play a key role in effectively dispersing the pressure generated by the weight of the materials, preventing the chain links from deforming, and ensuring that the materials move smoothly and continuously forward along the predetermined straight trajectory.

[0040] As shown in Figure 2 , the chain links are tightly connected through the cooperation of the connecting flanges 2, the connecting grooves 4, the clamping teeth and the plug-in interfaces. In the running process, the contact surface of the connecting flange 2 and the connecting groove 4 is coated with a nano self-lubricating coating, and the friction force is significantly reduced, not only reducing wear, but also making the relative movement of the chain links more smooth and reducing energy loss. At the same time, the connecting shaft 8 penetrates and fixes the positioning holes 1 of the adjacent chain links, bears the tensile force and shear force between the chain links, and ensures the stability of the connection of the chain links in the longitudinal direction.

[0041] The lock washer plays a crucial role in preventing loosening between the connecting shaft 8 and the edge of the connecting groove 4. When the connecting shaft 8 has a tendency to loosen due to external forces such as vibrations and impacts generated during equipment operation, the lock washer, with its elastic deformation and self-locking properties, automatically adjusts the gripping force to prevent the connecting shaft 8 from loosening. At this time, the micro strain sensor at the connection between the connecting groove 4 and the lock washer monitors the tightness of the lock washer in real time. Once the displacement exceeds the preset safety threshold (e.g., deviation less than 0.1 mm), an electrical signal is transmitted through the shielded wire to the central control system. Upon receiving the signal, the central control system alerts the operator to check and maintain the equipment in a timely manner. On the other hand, the system can record fault information according to the preset program, providing data support for subsequent equipment maintenance and fault analysis, ensuring the reliability and continuity of the conveying process.

[0042] In actual operation, due to installation errors, uneven material distribution, equipment aging or changes in operating environment, individual mesh belt links may experience positional deviation. When this occurs, the operator can manually adjust the adjusting screw outside the fixed block 7 to make fine adjustments. The adjusting screw rotates within the threaded hole of the fixed block 7 and produces axial displacement. Since one end of the adjusting screw is inserted into the link and connected to the elastic buffer, the axial displacement is transmitted to the link, pushing the link to produce a small adjustment in the horizontal or vertical direction, precisely compensating for the positional deviation.

[0043] The elastic buffer plays a crucial role in buffering and protecting during this adjustment process. When the adjusting screw applies force, the elastic buffer first absorbs part of the impact force, preventing direct impact on the internal structure of the link and preventing damage. For example, if the adjusting screw is rotated quickly, the instantaneous impact force is large. The elastic buffer of the rubber pad or spring structure can buffer the energy in the form of elastic deformation, allowing the link to smoothly and slowly adjust its position, maintaining the overall running accuracy of the mesh belt chain and ensuring the accuracy and stability of material conveying.

[0044] The matching fillets inside the connecting groove 4 and at the top of the connecting flange 2 have multiple functions. When conveying fragile, easily scratched or high-surface-precision materials, the fillet design effectively reduces stress concentration at the contact points between the material and the link, preventing damage to the material during conveying due to collisions and scratches. At the same time, the fillet also reduces wear and tear on the link connection during movement, extending the service life of the link.

[0045] The drip hole 6 at the upper end of the fixed block 7 plays an important role in the conveying of water-containing materials. When conveying materials such as fruits, vegetables after cleaning, or mineral products after water washing, the water carried by the materials can be quickly discharged through the drip hole 6, the guide hole 5 formed, and the rectangular grid 3, preventing water accumulation on the chain links, avoiding problems such as material sticking, chain link corrosion, or bacterial growth caused by water accumulation. This not only helps to maintain the quality and hygiene of the materials, but also reduces the frequency and difficulty of equipment cleaning and maintenance, improves the wide adaptability of the conveying module to different material characteristics, reduces operating costs, and improves production efficiency.

[0046] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made in terms of structure, shape, and principle should be covered within the scope of protection of the present application.
