[0028] In modern industrial production, logistics warehousing, and automated assembly, conveying devices play a crucial role as core equipment for enabling the flow of materials between various workstations. As market demands become increasingly diversified and personalized, modern manufacturing production lines often need to accommodate products of various specifications and sizes. This necessitates that the conveying channels of the conveying devices be able to adjust their width according to actual production needs.

[0029] To achieve adjustable conveying width, traditional conveying equipment typically employs complex mechanical designs, such as multi-stage screw drives, numerous linear guides, handwheels, and complicated locking accessories. These additional structural components not only significantly increase the overall manufacturing cost and assembly difficulty, resulting in bulky and cumbersome equipment, but also make subsequent maintenance and upkeep extremely complicated.

[0030] To solve the above problems, please refer to... Figures 1 to 6 The present invention proposes a conveying device 100, including a frame 1, a conveying mechanism 2, and a width adjustment mechanism 3. The conveying mechanism 2 includes a first driving member 21, a transmission shaft 22, and two sets of double-speed chains 23. The two sets of double-speed chains 23 are connected to the transmission shaft 22 at intervals. The output end of the first driving member 21 is connected to the transmission shaft 22 and can drive the transmission shaft 22 to drive the two double-speed chains 23 to move synchronously to achieve conveying. The width adjustment mechanism 3 includes a second driving member 31 and a connecting component 32. The connecting component 32 is respectively connected to at least one set of double-speed chains 23 and the output end of the second driving member 31. The second driving member 31 drives the connecting component 32 to move the double-speed chain 23 closer to or away from the other double-speed chain 23.

[0031] The present invention provides a conveying device 100, mainly used in automated production lines, logistics sorting, electronic component assembly, food processing, and other fields. It is used to achieve continuous and stable conveying of workpieces, materials, and products, providing connection support for subsequent processing, sorting, assembly, and other processes. The conveying device 100 includes a frame 1, a conveying mechanism 2, and a width adjustment mechanism 3. The frame 1 provides basic support for the entire conveying device 100. The conveying mechanism 2 drives the material to achieve the conveying action. The width adjustment mechanism 3 adjusts the spacing of the two sets of double-speed chains 23 to adapt to the conveying needs of materials of different sizes. The three mechanisms work together to achieve efficient material conveying and flexible adaptation, improving the automation level and production efficiency of the production line.

[0032] The frame 1, as the basic supporting component of the conveying device 100, possesses sufficient load-bearing capacity and structural stability to withstand the weight of the conveying mechanism 2, the width adjustment mechanism 3, and the conveyed materials, preventing the equipment from tipping over, shaking, or deforming during operation. The dimensions of the frame 1 can be flexibly designed according to production scenarios and conveying requirements, with ample installation space reserved to facilitate the installation, commissioning, and subsequent maintenance of components such as the conveying mechanism 2 and the width adjustment mechanism 3. The surface of the frame 1 undergoes rust removal and anti-corrosion treatment to prevent rusting during long-term use and extend the equipment's service life. The frame 1 is equipped with multiple precise mounting holes and positioning structures to ensure the accurate installation of the drive shaft 22 of the conveying mechanism 2, the speed-multiplying chain 23, and the connecting assembly 32 of the width adjustment mechanism 3, guaranteeing the precision of the fit between components and ensuring stable operation of the equipment.

[0033] The conveying mechanism 2 includes a first drive component 21, a drive shaft 22, and two sets of double-speed chains 23. The first drive component 21 serves as the power source for the conveying mechanism 2 and employs a speed-adjustable servo motor or stepper motor, featuring strong power, stable speed, and precise control. It can flexibly adjust the conveying speed according to conveying requirements and adapt to the conveying requirements of materials of different weights and sizes. The drive shaft 22 is connected to the frame 1 and is made of high-strength, wear-resistant alloy steel, capable of withstanding the torque transmitted by the first drive component 21 and the tension of the double-speed chains 23, preventing bending, deformation, or breakage. The two sets of double-speed chains 23 are connected to the drive shaft 22 at intervals. The double-speed chains 23 adopt a high-strength chain structure 233, featuring strong load-bearing capacity, high transmission efficiency, and low wear, and can stably drive the material forward. The output end of the first drive unit 21 is connected to the drive shaft 22, and can drive the drive shaft 22 to drive the two sets of double speed chains 23 to move synchronously to achieve conveying. This driving method ensures that the movement speed of the two sets of double speed chains 23 is completely consistent, avoids material conveying deviation due to speed difference, and ensures the stability and accuracy of conveying.

[0034] The width adjustment mechanism 3 includes a second drive component 31 and a connecting component 32. The second drive component 31 uses a servo motor or a stepper motor, featuring precise adjustment and rapid response. It can accurately control the movement distance of the connecting component 32, thereby achieving precise adjustment of the spacing between the speed-multiplying chains 23. The connecting component 32 connects at least one set of speed-multiplying chains 23 to the output end of the second drive component 31. The connecting component 32 adopts a high-strength transmission structure to ensure stable power transmission and avoid loosening or slippage. The second drive component 31 drives the connecting component 32 to move the speed-multiplying chains 23 closer to or further away from the other set of speed-multiplying chains 23. When conveying materials of different widths, the second drive component 31 adjusts the spacing between the two sets of speed-multiplying chains 23 to adapt to the width of the materials, ensuring that the materials can be placed stably on the two sets of speed-multiplying chains 23 and preventing the materials from falling or deviating during the conveying process. The structural design of the connecting component 32 takes into account both transmission stability and adjustment flexibility, and can drive the double-speed chain 23 to move smoothly under the drive of the second drive component 31 without problems such as jamming or deviation.

[0035] The frame 1 provides stable mounting support for the conveying mechanism 2 and the width adjustment mechanism 3, ensuring precise coordination and stable operation of all components. The first drive component 21 of the conveying mechanism 2 drives the transmission shaft 22 to rotate, and the transmission shaft 22 drives two sets of double-speed chains 23 to move synchronously, realizing continuous material conveying. The second drive component 31 of the width adjustment mechanism 3 drives the double-speed chains 23 to move through the connecting component 32, adjusting the distance between the two sets of double-speed chains 23 to adapt to materials of different sizes. The conveying device 100 in this embodiment ensures conveying stability through two sets of synchronously moving double-speed chains 23, and achieves flexible distance adjustment through the width adjustment mechanism 3. It effectively solves the problems of fixed distance, poor adaptability, and easy material deviation in traditional conveying devices 100, improves the accuracy and flexibility of conveying, reduces manual intervention, improves the automation efficiency and production quality of the production line, and adapts to the conveying needs of various specifications of materials.

[0036] Furthermore, in one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 Each speed-multiplying chain 23 includes a drive wheel 231, an idler wheel 232, and a chain 233. The drive wheel 231 and the idler wheel 232 are located at opposite ends along the conveying direction of the speed-multiplying chain 23. The chain 233 is wound around the drive wheel 231 and the idler wheel 232 and meshes with the drive wheel 231 and the idler wheel 232. The drive wheel 231 is connected to the drive shaft 22.

[0037] Both the driving wheel 231 and the idler wheel 232 are made of high-strength, wear-resistant metal materials, and their surfaces are hardened to withstand the tension of the chain 233 and the pressure of the material, preventing wear and deformation. The driving wheel 231 and idler wheel 232 are located at opposite ends along the conveying direction of the double-speed chain 23, providing stable support and guidance for the chain 233 and ensuring its smooth operation. The chain 233 is wound around the driving wheel 231 and idler wheel 232 and meshes with them. This meshing transmission ensures precise power transmission without slippage. When the driving wheel 231 rotates, it drives the chain 233 through meshing, which in turn drives the idler wheel 232 to rotate synchronously, forming a complete closed-loop transmission. The driving wheel 231 is connected to the drive shaft 22. When the drive shaft 22 rotates, it drives the driving wheel 231 to rotate synchronously, which in turn drives the chain 233 and idler wheel 232, realizing the conveying action of the double-speed chain 23. This structural design makes the transmission of the double-speed chain 23 more stable, and the chain 233 runs smoothly without problems such as deviation or jamming. At the same time, the meshing transmission efficiency is high, which can effectively transmit power, ensure the continuity and stability of material conveying, adapt to the conveying needs of materials of different weights, and extend the service life of the double-speed chain 23.

[0038] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 4 as well as Figure 5 The conveying mechanism 2 also includes a first mounting box 24, a profile 25, and a second mounting box 26 arranged sequentially along the conveying direction. The profile 25 covers the circumference of the chain 233, and the top of the chain 233 is exposed in the profile 25. The first mounting box 24 forms a first mounting cavity, and the drive wheel 231 is disposed in the first mounting cavity, and the chain 233 portion at the top of the drive wheel 231 is exposed in the top of the first mounting box 24. The second mounting box 26 forms a second mounting cavity, and the idler wheel 232 is disposed in the second mounting cavity, and the chain 233 portion at the top of the idler wheel 232 is exposed in the top of the second mounting box 26.

[0039] The first mounting box 24, the profile 25, and the second mounting box 26 are all made of high-strength, lightweight aluminum alloy, balancing structural strength and lightweight requirements, and facilitating installation and adjustment. The profile 25 covers the circumference of the chain 233, protecting it from contamination and impacts from external impurities, and preventing loosening or detachment during operation. The profile 25 also guides the chain 233, ensuring it runs along a preset trajectory. The top of the chain 233 protrudes from the profile 25, ensuring contact with materials for material transport. The first mounting cavity formed by the first mounting box 24 accommodates the drive wheel 231, providing a sealed protection against dust and debris, and fixing its position for stable operation. The chain 233 at the top of the driving wheel 231 is exposed at the top of the first mounting box 24, ensuring that the chain 233 can mesh and transmit power normally and support materials properly. The second mounting cavity formed by the second mounting box 26 is used to accommodate the idler wheel 232, and its function is the same as that of the first mounting box 24, ensuring the stable operation of the idler wheel 232. This structural design makes the double-speed chain 23 more compact, stable, and better protected, ensuring the normal operation of the chain 233, extending the service life of the double-speed chain 23, and improving the reliability of the conveying device 100.

[0040] Further, please refer to Figure 3 , Figure 4 as well as Figure 5 The first mounting box 24 includes a first box body 241, a first cover 242, and a first sealing plate 243. The first cover 242 and the first sealing plate 243 are respectively disposed on opposite sides of the first box body 241 along the vertical direction. The drive wheel 231 and part of the chain 233 are disposed on the first box body 241. The first cover 242 has a through hole to expose the chain 233 at the top of the drive wheel 231. The second mounting box 26 includes a second box body 261, a second cover 262, and a second sealing plate 263. The second cover 262 and the second sealing plate 263 are respectively disposed on opposite sides of the second box body 261 along the vertical direction. The idler wheel 232 and part of the chain 233 are disposed on the second box body 261. The second cover 262 has a through hole to expose the chain 233 at the top of the idler wheel 232.

[0041] The first housing 241, first cover 242, and first sealing plate 243 are all made of aluminum alloy and are fixedly connected by bolts to ensure a firm connection and structural stability. This split-type assembly and disassembly structure facilitates the installation of the drive wheel 231, transition wheel, and chain 233. The first cover 242 and the first sealing plate 243 are respectively located on opposite sides of the first housing 241 along the vertical direction, forming a closed first mounting cavity, which provides comprehensive protection for the drive wheel 231 and part of the chain 233, preventing external impurities from entering. The through hole formed by the first cover 242 is adapted to the size of the chain 233, allowing the chain 233 at the top of the drive wheel 231 to be exposed, ensuring that the chain 233 can properly mesh and transmit power and support materials without affecting material conveying. The structure of the second housing 261, second cover 262, and second sealing plate 263 is the same as that of the first mounting box 24. The split-type assembly and disassembly structure facilitates the installation of the idler wheel 232 and chain 233. The second cover 262 and the second sealing plate 263 are respectively disposed on opposite sides of the second housing 261 along the vertical direction, forming a closed second mounting cavity, which provides sealing protection for the idler wheel 232 and part of the chain 233. The through hole formed by the second cover 262 is used to expose the chain 233 at the top of the idler wheel 232, ensuring its normal operation. This structural design makes the protection of the first mounting box 24 and the second mounting box 26 more comprehensive and the assembly more convenient. It protects the core components of the double-speed chain 23 without affecting its normal operation, further improving the structural reliability of the conveying device 100.

[0042] In one embodiment, please refer to Figure 3 , Figure 4 as well as Figure 5 The conveying mechanism 2 also includes a first transition wheel 27 and a second transition wheel 28. The first transition wheel 27 and the second transition wheel 28 are arranged between two adjacent double speed chains 23 along the conveying direction of the double speed chain 23. The first transition wheel 27 is located inside the first mounting box 24 and is partially exposed at the top of the first mounting box 24. The first transition wheel 27 is located on the side of the moving wheel 231 facing away from the idler wheel 232 and is connected to the drive shaft 22. The second transition wheel 28 is located inside the second mounting box 26 and is partially exposed at the top of the second mounting box 26. The second transition wheel 28 is located on the side of the idler wheel 232 facing away from the moving wheel 231 and is rotatably connected to the side wall of the second mounting box 26.

[0043] The first transition wheel 27 and the second transition wheel 28 are designed to assist in supporting the material, preventing it from being suspended or jammed between the two sets of double-speed chains 23. They also further improve the stability of material conveying, ensuring smooth passage through the gap between the two sets of double-speed chains 23. The first transition wheel 27 and the second transition wheel 28 are made of smooth, wear-resistant metal. Their outer diameter is the same as the height of the top of the chain 233, ensuring that the material can be placed stably on the transition wheel and chain 233 without any height difference causing the material to shake or fall. The first transition wheel 27 and the second transition wheel 28 are positioned between adjacent double-speed chains 23 along the conveying direction of the double-speed chains 23. Specifically, the first transition wheel 27 and the driving wheel 231 are spaced apart within the first housing 241 and connected to the drive shaft 22 via a belt drive. The first cover 242 also has corresponding through holes, allowing the first transition wheel 27 to partially expose itself so that it can contact the material above it. The second transition wheel 28 and idler wheel 232 are spaced apart within the second housing 261 and rotatably connected to the side wall of the second housing 261. A corresponding through hole is also provided on the second cover 262, allowing the second transition wheel 28 to partially protrude from the cover 262 so that it can contact the material above. The first transition wheel 27 and the second transition wheel 28 are positioned between adjacent double-speed chains 23 along the conveying direction of the double-speed chain 23. In actual conveying production lines, due to the length of the conveying path, the entire conveying production line may consist of two or more conveying mechanisms 2 connected along the conveying direction. The first transition wheel 27 and the second transition wheel 28 are positioned at the gap between the connections to prevent material jamming at the connection point when conveying smaller materials. For example, at the docking point, the driving wheel 231 of the first set of double-speed chains 23 corresponds to the idler wheel 232 of the second set of double-speed chains 23. The first transition wheel 27 on the first set of double-speed chains 23 is driven by the driving wheel 231, and the second transition wheel 28 and idler wheel 232 on the second set of double-speed chains 23 are spaced apart, forming a transmission path of driving wheel 231-first transition wheel 27-second transition wheel 28-idler wheel 232 at the docking position. Since the first transition wheel 27 is driven by the drive shaft 22 and also has conveying power, when conveying some small-sized materials, the first transition wheel provides power to move them closer to the second transition wheel 28, and then conveys them to the next set of double-speed chains 23 to continue moving forward. This ensures that the material receives stable support and conveying power throughout the entire conveying process. The first transition wheel 27 and the second transition wheel 28 fill the gap between the two sets of double-speed chains 23, solving the problem of materials being easily suspended or jammed in the gap, further improving the stability and smoothness of material conveying, ensuring that materials can be conveyed completely and stably to the target position, and improving the practicality and reliability of the conveying device 100.

[0044] Further, please refer to Figure 5The conveying mechanism 2 also includes an idler shaft 29, with an idler 232 rotatably connected to the idler shaft 29. The side wall of the second mounting box 26 has a through adjustment hole 261a, which extends along the extension direction of the speed-multiplying chain 23. The idler shaft 29 is connected to the second mounting box 26 and passes through the adjustment hole 261a. The idler shaft 29 can be adjusted in its installation position within the adjustment hole 261a to adjust the distance between the idler 232 and the moving wheel 231.

[0045] The idler shaft 29 is made of high-strength metal material, which can stably support the idler wheel 232 and ensure that the idler wheel 232 can rotate flexibly. The idler wheel 232 is rotatably connected to the idler shaft 29, and a bearing is provided between the two to reduce rotational friction and ensure that the idler wheel 232 can rotate smoothly and synchronously with the chain 233. The adjustment hole 261a formed in the side wall of the second mounting box 26 extends along the extension direction of the double-speed chain 23, providing space for the movement of the idler shaft 29. The idler shaft 29 is connected to the second mounting box 26 and passes through the adjustment hole 261a, and is fixed in the adjustment hole 261a by bolts or other fasteners. When it is necessary to adjust the tension of the chain 233, the fasteners are loosened, and the idler shaft 29 is pushed to move along the extension direction of the adjustment hole 261a, thereby adjusting the distance between the idler wheel 232 and the drive wheel 231. When the chain 233 reaches the appropriate tension, the fasteners are tightened to fix the position of the idler shaft 29. This adjustment method is simple and convenient, allowing for the adjustment of chain 233 tension without disassembling the speed-reducing chain 23, saving maintenance time and improving operational efficiency. Simultaneously, by adjusting the position of the idler wheel 232, it ensures that the chain 233 maintains appropriate tension at all times, guaranteeing the transmission stability of the speed-reducing chain 23, reducing chain 233 wear, extending the service life of the chain 233, idler wheel 232, and drive wheel 231, and further improving the operational stability of the conveyor device 100.

[0046] In another embodiment, please refer to Figure 5 The second mounting box 26 is also equipped with a protective plate 291, which is connected to the idler shaft 29 and covers the adjustment hole 261a.

[0047] The protective plate 291 is designed to cover the adjustment hole 261a, preventing dust, debris, and other external impurities from entering the second mounting cavity through the adjustment hole 261a and contaminating the idler wheel 232, idler wheel shaft 29, and chain 233, thus avoiding interference with the normal operation of these components. It also provides auxiliary fixation for the idler wheel shaft 29, improving its installation stability. The protective plate 291 is made of wear-resistant and corrosion-resistant metal or plastic sheet, and its size is sufficient to completely cover the adjustment hole 261a, ensuring effective protection. The protective plate 291 is connected to the idler wheel shaft 29 and moves synchronously with it. Regardless of the position of the idler wheel shaft 29 within the adjustment hole 261a, the protective plate 291 always covers the adjustment hole 261a, preventing impurities from entering. The protective plate 291 fits tightly against the inner wall of the second mounting box 26, and a sealing gasket can be placed between them to further enhance the sealing and protection effect, preventing dust, oil, and other contaminants from entering the second mounting cavity. The protective plate 291 not only provides good protection and extends the service life of each component of the double-speed chain 23, but also helps to fix the idler shaft 29, preventing the idler shaft 29 from shaking during operation, ensuring the stability of the idler 232, thereby ensuring the transmission stability of the chain 233 and improving the reliability and service life of the conveying device 100.

[0048] In one embodiment, please refer to Figure 2 , Figure 3 as well as Figure 6 Each speed chain 23 is connected to at least one set of connecting components 32. The connecting components 32 include a lead screw 321 and a nut 322. The lead screw 321 is connected to the output end of the second drive member 31. The nut 322 is screwed to the lead screw 321 and detachably connected to the profile 25. The two lead screws 321 are connected to the output end of the second drive member 31 for transmission.

[0049] The lead screw 321 of the connecting assembly 32 is a high-strength, high-precision ball screw 321, characterized by precise adjustment, high transmission efficiency, and low wear. It can accurately transmit the power of the second drive component 31, realizing precise adjustment of the spacing of the double-speed chain 23. The nut 322 is screwed to the lead screw 321, using a ball nut 322, which cooperates with the ball screw 321 to reduce transmission friction and improve the smoothness and accuracy of adjustment. The nut 322 is detachably connected to the profile 25 and fixed by bolts, facilitating installation, disassembly, and maintenance. When it is necessary to replace or repair the double-speed chain 23, the nut 322 can be quickly removed to separate the connecting assembly 32 from the double-speed chain 23. Each double-speed chain 23 is connected to at least one set of connecting assemblies 32 to ensure that the double-speed chain 23 can be subjected to force smoothly and evenly, avoiding deviation during adjustment. Two lead screws 321 are connected to the output ends of the second drive unit 31 via a gearbox or coupling 4 for synchronous transmission. This ensures that when the second drive unit 31 starts, the two lead screws 321 rotate synchronously, thereby driving the two nuts 322 to move synchronously. This allows the two sets of double-speed chains 23 to move simultaneously, adjusting their positions to meet the material conveying needs of different workstations. When adjusting the distance between the two double-speed chains 23 to meet the conveying requirements of materials of different sizes, simply disengage the ball nuts 322 on one set of double-speed chains 23 from the corresponding profile 25. The second drive unit 31 then drives the other set of double-speed chains 23 to move, thus adjusting the distance between the two sets of double-speed chains 23. In this embodiment, second drive units 31 are provided at both ends along the conveying direction of the double-speed chains 23 to achieve synchronous adjustment of both ends of the double-speed chains 23, preventing positional deviations in the two sets of double-speed chains 23 during adjustment and avoiding material conveying deviation. Furthermore, each of the second drive components 31 is connected to the same end of the two sets of double speed chains 23 via belt drive, so as to realize the synchronous adjustment of the position of the two sets of double speed chains 23, or to realize the adjustment of one set of double speed chains 23 relative to the other set of double speed chains 23. This simplifies the structure of the conveying device 100 and facilitates the realization of width and position adjustment, thereby improving the versatility of the conveying device 100.

[0050] In another embodiment, please refer to Figure 1 , Figure 3 as well as Figure 4 The conveying mechanism 2 also includes a coupling 4, with the two ends of the coupling 4 connected axially to the transmission shaft 22 and the output end of the first driving member 21, respectively.

[0051] The coupling 4 is used to achieve a flexible connection between the first driving component 21 and the transmission shaft 22. While transmitting power, it compensates for coaxiality deviation between the output end of the first driving component 21 and the transmission shaft 22, preventing excessive vibration and noise during equipment operation due to coaxiality deviation and extending the equipment's service life. The coupling 4 is made of high-strength, high-toughness metal material, preferably an elastic coupling 4, possessing a certain elastic deformation capacity to absorb vibration and impact during equipment operation, reducing damage to the first driving component 21 and the transmission shaft 22. The two axial ends of the coupling 4 are respectively fixedly connected to the output ends of the transmission shaft 22 and the first driving component 21 by bolts, ensuring a firm connection and effectively transmitting the torque of the first driving component 21. This ensures that the power of the first driving component 21 can be stably transmitted to the transmission shaft 22, driving the transmission shaft 22 and the speed-multiplying chain 23 to move synchronously. The flexible connection characteristics of the elastic coupling 4 can effectively compensate for installation deviations between the first driving component 21 and the transmission shaft 22. Even if there is a slight coaxiality deviation, it will not affect the stability of power transmission, avoiding problems such as jamming and abnormal noise. The coupling 4 improves the power transmission stability of the conveying mechanism 2, reduces vibration and noise during equipment operation, protects the first drive component 21 and the transmission shaft 22, extends the service life of the entire conveying mechanism 2, and ensures that the conveying device 100 can operate stably for a long time. Furthermore, the coupling 4 also helps improve the versatility of the conveying device 100, facilitating subsequent component updates and maintenance. For example, when it is necessary to replace a different model of drive component, only the component at one end of the coupling 4 needs to be disassembled and replaced.

[0052] Further, please refer to Figure 1 , Figure 2 as well as Figure 3 The conveying device 100 also includes a guide assembly 5, which includes a guide rail 51 and a slider 52. The guide rail 51 extends along the extension direction of the connecting assembly 32, and the slider 52 is connected to the connecting assembly 32 and can slide along the extension direction of the guide rail 51. The speed-multiplying chain 23 is connected to the slider 52.

[0053] The guide component 5 provides precise guidance for the movement of the speed-adjusting chain 23, ensuring that the speed-adjusting chain 23 moves smoothly along the preset direction during the width adjustment process, avoiding deviation and jamming, and ensuring the adjustment accuracy and stability of the width adjustment mechanism 3. The guide rail 51 is a high-strength, wear-resistant linear guide rail, extending along the extension direction of the connecting component 32 and fixedly connected to the frame 1. The smooth surface of the guide rail 51 reduces friction when the slider 52 slides, ensuring smooth sliding. The slider 52 slides in conjunction with the guide rail 51 and is connected to the connecting component 32. The slider 52 is made of wear-resistant material and has internal ball bearings to further reduce sliding friction and improve the smoothness and stability of sliding. The speed-adjusting chain 23 is connected to the slider 52. When the second drive component 31 drives the connecting component 32 to move, the connecting component 32 drives the slider 52 to slide along the guide rail 51. The slider 52 then drives the speed-adjusting chain 23 to move closer to or further away from another set of speed-adjusting chains 23, achieving spacing adjustment. The guide component 5 ensures the accuracy of the movement direction of the double speed chain 23, preventing the double speed chain 23 from deviating during the width adjustment process, which could lead to asynchronous movement of the two sets of double speed chains 23 and material conveying deviation. At the same time, it reduces the stress on the connecting component 32, preventing deformation and damage to the connecting component 32, improving the adjustment accuracy and structural reliability of the width adjustment mechanism 3, and further optimizing the overall performance of the conveying device 100.
