Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically a modular toothed belt conveyor. Background Technology

[0002] Toothed belt conveyors are widely used in automated production processes, their core function being the conveying, positioning, and sorting of materials. Compared to traditional flat belt conveyors, toothed belts, through their surface-designed toothed structure, significantly enhance the contact friction with materials, effectively preventing slippage and maintaining stable operation in inclined or vertical conveying scenarios. This characteristic has led to their widespread application in food processing, electronics manufacturing, logistics sorting, and mechanical assembly. With the increasing demands for industrial automation, toothed belt conveyors, due to their high efficiency and reliability, are gradually becoming a key component of modern flexible production lines.

[0003] However, existing toothed belt conveyor systems suffer from significant technical challenges in practical applications. Traditional toothed belts typically employ a monolithic structure, meaning the entire belt is continuously molded from a single material. While this ensures initial operational stability, long-term use can lead to performance degradation due to localized wear. For example, in food processing, frequent material friction, detergent corrosion, or high-temperature environments can cause wear and even breakage of the toothed belt's surface. In logistics sorting, high-intensity, high-frequency operation accelerates fatigue aging. Because the toothed belt is an indivisible unit, any wear or damage in a localized area necessitates replacing the entire belt. This maintenance method not only incurs high spare parts costs but also significantly increases production line downtime. For instance, replacing a 10-meter-long monolithic toothed belt on a certain automotive parts assembly line requires an average downtime of 4-6 hours, directly impacting production plans and causing economic losses. Furthermore, the monolithic design limits the adaptability of the equipment: when the production line layout is adjusted or the specifications of the conveyed materials change, users cannot quickly adjust the length or local structure of the toothed belt and need to re-customize the entire toothed belt, which further increases time and economic costs.

[0004] Based on this, we propose a modular toothed belt conveyor system. Through structural optimization and modular design, the traditional integral toothed belt is broken down into multiple independently replaceable standard modules. This design not only enables rapid replacement of locally worn sections to reduce maintenance costs. Utility Model Content

[0005] The purpose of this invention is to provide a modular toothed belt conveyor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The modular toothed belt conveyor includes two symmetrically arranged H-shaped supports for overall support. The two H-shaped supports are connected to two symmetrically arranged fixed side plates for fixing the mounting positions of the drive roller, driven roller, and tensioning components. A drive roller is rotatably connected between the two fixed side plates at the right end, serving as the power input to drive the modular toothed belt. A motor is located on the rear side of the rear fixed side plate to drive the drive roller, providing power output and rotating the drive roller via a transmission mechanism. Furthermore, a tensioning element is located at the left end to adjust the tension of the toothed belt, preventing it from becoming too loose or too tight. When replacing the toothed belt, the belt can also be loosened to facilitate replacement by the staff. The tensioning element is connected to a U-shaped plate, which fixes the driven roller and transmits the displacement for tension adjustment. The driven roller is rotatably connected between the front and rear sides of the inner wall of the U-shaped plate, cooperating with the driving roller to support the toothed belt and form a closed-loop conveying path. The driving roller and the driven roller are connected together to multiple toothed belts that are connected end to end. The modular design allows for the replacement of worn parts in sections to reduce maintenance costs.

[0008] The top of the modular toothed belt has multiple toothed plates arranged equidistantly from left to right. The toothed structure increases friction with the material, improving conveying stability. The top left side of the modular toothed belt has two symmetrically arranged first connecting blocks that mate with the second connecting slots of adjacent modules to secure them together. The top left side of the modular toothed belt also has three equidistant first connecting slots to accommodate the second connecting blocks of adjacent modules for connection. The bottom of the inner wall of each first connecting slot has two first internally threaded fixing blocks, each threadedly connected to a first clamping bolt, which clamps the second connecting blocks to lock the module in place. The module toothed belt has three second connecting blocks arranged equidistantly on the top right side. Two second connecting grooves are symmetrically arranged on the top right side of the module toothed belt. Two second internally threaded fixing blocks are embedded at the bottom of the inner wall of each second connecting groove. These second internally threaded fixing blocks are threaded with second clamping bolts, which clamp the first connecting blocks to lock the module connection. The first connecting block of the right module toothed belt mates with the second connecting groove of the left module toothed belt, and vice versa. This staggered connection achieves bidirectional locking between modules, preventing misalignment.

[0009] Preferably, the tensioning component includes a fixed longitudinal plate fixed between the fixed side plates, serving as the mounting base for the tension adjustment mechanism. The front and rear sides of the fixed longitudinal plate are respectively fixedly connected to the opposite sides of the two fixed side plates. A rectangular cover is provided in the middle of the right side of the fixed longitudinal plate. A threaded rod is rotatably connected inside the rectangular cover. The rectangular connecting column is moved laterally by rotation to achieve tension adjustment. The outer wall of the threaded rod is rotatably connected to the rectangular connecting column, which converts the rotational motion of the threaded rod into the lateral displacement of the U-shaped plate. The left side of the rectangular connecting column passes through the right side of the fixed longitudinal plate and is fixedly connected to the right side of the U-shaped plate, transmitting the adjustment displacement to the driven roller to change the tension of the module toothed belt.

[0010] Preferably, the tensioning component further includes a drive mechanism, which includes an L-shaped fixing plate to fix the drive mechanism and ensure transmission stability. The front side of the L-shaped fixing plate is fixedly connected to the rear side of the front fixed side plate. A rotating rod is rotatably connected to the rear side of the inner wall of the L-shaped fixing plate to transmit the rotational power of the knob to the driving bevel gear. The front end of the rotating rod passes through the rear side of the fixed side plate and is fixedly connected to the knob, providing a manual operation interface to control the tension adjustment. The rear end of the rotating rod passes through the inner side of the L-shaped fixing plate and is connected to the driving bevel gear, meshing with the driven bevel gear to transmit the rotational power to the threaded rod. The right end of the threaded rod passes through the right side of the inner wall of the rectangular cover and is connected to the driven bevel gear that meshes with the driving bevel gear, converting the power transmitted by the bevel gear into the rotational motion of the threaded rod.

[0011] Preferably, the right side of the U-shaped plate is provided with two positioning crossbars arranged symmetrically front to back. The right end of the positioning crossbars passes through the left side of the fixed longitudinal plate to restrict the U-shaped plate to move only in the horizontal direction and ensure adjustment accuracy.

[0012] Preferably, the bottom of the first connecting block has a first mounting hole through which the second internally threaded fixing block passes, and the second clamping bolt is pressed against the top of the first connecting block to achieve lateral fixation between the modules through threaded locking.

[0013] Preferably, the bottom of the second connecting block has a second mounting hole through which the first internally threaded fixing block passes, and the first clamping bolt is pressed against the top of the second connecting block to achieve lateral fixation between the modules through threaded locking.

[0014] Preferably, the bottom of the inner wall of the first connecting groove is provided with four first anti-detachment blocks arranged in a matrix, and the front and rear sides of the second connecting block are provided with second anti-detachment grooves for the first anti-detachment blocks to be inserted, so as to prevent the module from loosening during vibration and improve the impact resistance of the connecting structure.

[0015] Preferably, the bottom of the inner wall of the second connecting groove is provided with four second anti-detachment blocks arranged in a matrix, and the front and rear sides of the first connecting block are provided with first anti-detachment grooves for the second anti-detachment blocks to be inserted, so as to prevent the module from loosening during vibration and improve the impact resistance of the connecting structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This modular toothed belt conveyor system, through its modular toothed belt design, can decompose the traditional integral toothed belt into multiple independent and replaceable units. When the performance of a local area deteriorates due to wear, corrosion, or breakage, only the damaged module needs to be disassembled and replaced, avoiding the scrapping and repurchase of the entire toothed belt, reducing maintenance costs and downtime. The quick adjustment function of the tensioning parts can quickly loosen the modular toothed belt, further shortening maintenance operation time and reducing economic losses caused by production line downtime.

[0018] 2. This modular toothed belt conveyor, through its staggered connection and bidirectional locking design, combined with the insertion relationship between the first connecting block and the second connecting groove, and the second connecting block and the first connecting groove, ensures a stable connection between modules. The design of the first anti-detachment block and the second anti-detachment groove prevents the modules from loosening during vibration or frequent operation, improving the impact resistance of the connection structure. The staggered connection and bidirectional locking design between modules ensures that there is no misalignment or loosening between modules, thus improving the stability of the conveying process.

[0019] 3. This modular toothed belt conveyor uses a threaded rod and bevel gear transmission mechanism for the tensioning component. The tension of the modular toothed belt can be precisely controlled by manual fine adjustment via a knob, avoiding conveying stability issues caused by improper tension. The cooperation between the positioning crossbar and the fixed longitudinal plate restricts the U-shaped plate to move only in the horizontal direction, ensuring adjustment accuracy and preventing equipment operation deviations caused by inaccurate adjustment.

[0029] Please see Figures 1-6 This utility model provides a technical solution:

[0030] The modular toothed belt conveyor includes two symmetrically arranged H-shaped supports 1 for providing overall support. The two H-shaped supports 1 are connected to two symmetrically arranged fixed side plates 2 for fixing the mounting positions of the drive roller 5, driven roller 6, and tensioning element 3. The drive roller 5 is rotatably connected between the two fixed side plates 2 at the right end, serving as the power input to drive the modular toothed belt 8. A motor 7 is located on the rear side of the rear fixed side plate 2 to drive the drive roller 5, providing power output and rotating the drive roller 5 via a transmission mechanism. A tensioning element 3 is located at the left end to adjust the tension of the modular toothed belt 8, preventing it from becoming too loose or too tight. When replacing the modular toothed belt 8, it can also be loosened to facilitate replacement by the staff. The tensioning element 3 is connected to a U-shaped plate 4, which fixes the driven roller 6 and transmits the displacement for tension adjustment. The driven roller 6 is rotatably connected between the front and rear sides of the inner wall of the U-shaped plate 4, and cooperates with the driving roller 5 to support the modular toothed belt 8 to form a closed-loop conveying path. The driving roller 5 and the driven roller 6 are connected together to multiple modular toothed belts 8 that are connected end to end. The modular design allows for the replacement of worn parts in sections to reduce maintenance costs.

[0031] The top of the modular toothed belt 8 is provided with multiple toothed plates 80 arranged equidistantly from left to right. The toothed structure increases the friction with the material, improving conveying stability. The top left side of the modular toothed belt 8 has two first connecting blocks 81 arranged symmetrically front to back, which mate with the second connecting grooves 84 of adjacent modules to fix the modules together. The top left side of the modular toothed belt 8 has three first connecting grooves 83 arranged equidistantly from front to back, accommodating the second connecting blocks 82 of adjacent modules for connection.

The staggered connection achieves bidirectional locking between modules and prevents misalignment.

[0032] In this embodiment, the tensioning component 3 includes a fixed longitudinal plate 30, which is fixed between the fixed side plates 2 and serves as the mounting base for the tension adjustment mechanism. The front and rear sides of the fixed longitudinal plate 30 are respectively fixedly connected to the opposite sides of the two fixed side plates 2. A rectangular cover 31 is provided in the middle of the right side of the fixed longitudinal plate 30. A threaded rod 32 is rotatably connected inside the rectangular cover 31. The rectangular connecting column 33 is rotatably connected to the outer wall of the threaded rod 32, which converts the rotational movement of the threaded rod 32 into the lateral displacement of the U-shaped plate 4. The left side of the rectangular connecting column 33 passes through the right side of the fixed longitudinal plate 30 and is fixedly connected to the right side of the U-shaped plate 4, transmitting the adjustment displacement to the driven roller 6 to change the tension of the module toothed belt 8.

[0033] Specifically, the tensioning component 3 also includes a drive mechanism 34, which includes an L-shaped fixing plate 340. The drive mechanism 34 is fixed and ensures transmission stability. The front side of the L-shaped fixing plate 340 is fixedly connected to the rear side of the front fixed side plate 2. The rear side of the inner wall of the L-shaped fixing plate 340 is rotatably connected to a rotating rod 341, which transmits the rotational power of the knob 343 to the driving bevel gear 342. The front end of the rotating rod 341 passes through the rear side of the fixed side plate 2 and is fixedly connected to the knob 343, providing a manual operation interface to control the tension adjustment. The rear end of the rotating rod 341 passes through the inner side of the L-shaped fixing plate 340 and is connected to the driving bevel gear 342, which meshes with the driven bevel gear 320, transmitting the rotational power to the threaded rod 32. The right end of the threaded rod 32 passes through the right side of the inner wall of the rectangular cover 31 and is connected to the driven bevel gear 320, which meshes with the driving bevel gear 342, converting the power of the bevel gear transmission into the rotational motion of the threaded rod 32.

[0034] Furthermore, two positioning crossbars 40 are provided on the right side of the U-shaped plate 4, which are arranged symmetrically front to back. The right end of the positioning crossbars 40 passes through the left side of the fixed longitudinal plate 30 to restrict the U-shaped plate 4 to move only in the horizontal direction and ensure adjustment accuracy.

[0035] Furthermore, the bottom of the first connecting block 81 is provided with a first mounting hole 811 through which the second internal threaded block 87 passes, and the second clamping bolt 88 is pressed against the top of the first connecting block 81, thereby achieving lateral fixation between modules through threaded locking.

[0036] Furthermore, the bottom of the second connecting block 82 is provided with a second mounting hole 821 for the first internal threaded fixing block 85 to pass through, and the first clamping bolt 86 is pressed against the top of the second connecting block 82 to achieve lateral fixation between modules through threaded locking.

[0037] Furthermore, the bottom of the inner wall of the first connecting groove 83 is provided with four first anti-detachment blocks 830 arranged in a matrix, and the front and rear sides of the second connecting block 82 are provided with second anti-detachment grooves 820 for the first anti-detachment blocks 830 to be inserted into, so as to prevent the module from loosening during vibration and improve the impact resistance of the connection structure.

[0038] Furthermore, the bottom of the inner wall of the second connecting groove 84 is provided with four second anti-detachment blocks 840 arranged in a matrix. The front and rear sides of the first connecting block 81 are provided with first anti-detachment grooves 810 for the second anti-detachment blocks 840 to be inserted into, so as to prevent the module from loosening during vibration and improve the impact resistance of the connection structure.

[0039] In this embodiment, when using the modular toothed belt conveyor, the first connecting block 81 of the right module needs to be aligned with the second connecting groove 84 of the left module during installation of the modular toothed belt 8. The second connecting block 82 of the left module is interleaved with the first connecting groove 83 of the right module. Then, the first internal threaded fixing block 85 is screwed into the first clamping bolt 86 and tightened, and the second internal threaded fixing block 87 is screwed into the second clamping bolt 88 and tightened. At this time, the first anti-detachment block 830 in the first connecting groove 83 is inserted into the second anti-detachment groove 820 of the second connecting block 82, and the second anti-detachment block 840 in the second connecting groove 84 is inserted into the first anti-detachment groove 810 of the first connecting block 81 to achieve bidirectional anti-detachment locking. Adjust the modular toothed belt. When the tension of the U-shaped belt 8 is adjusted, the knob 343 of the tensioning element 3 drives the rotating rod 341 to engage the driving bevel gear 342 and the driven bevel gear 320, causing the threaded rod 32 to rotate within the rectangular cover 31 and push the rectangular connecting column 33 to move laterally, thereby causing the U-shaped plate 4 and the driven roller 6 to move horizontally. At the same time, the positioning crossbar 40 passes through the fixed longitudinal plate 30 to restrict the U-shaped plate 4 to move only in the horizontal direction to ensure adjustment accuracy. When a local module is worn and needs to be replaced, the module toothed belt 8 can be loosened by the tensioning element 3, the damaged module can be removed, a new module can be replaced, the clamping bolts can be tightened again, and the tension can be adjusted to quickly restore operation. The entire process achieves efficient maintenance through modular design and staggered connection mechanism, significantly reducing downtime and maintenance costs.
