Description

Technical Field

[0001] This utility model belongs to the field of glass conveying equipment, and specifically relates to a glass conveying system with an adjustable conveying surface. Background Technology

[0002] In existing mold forming production lines, the forming mold must be paired with a conveying system to realize the feeding, forming and unloading of glass sheets. The existing conveying system has a complex structure and is inconvenient to install and adjust. Once assembled, when the shape or size of the glass changes and the shape of the conveying surface needs to be adjusted, the adjustment or disassembly and installation is complicated, resulting in inflexible adjustment of the conveying surface and unstable power transmission during the adjustment process. Utility Model Content

[0003] The purpose of this invention is to provide a glass conveying system with an adjustable conveying surface, which can adjust the shape of the conveying surface by lifting and lowering, and can ensure stable power transmission to the conveying surface before and after adjustment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a glass conveying system with an adjustable conveying surface, including a frame and a main transmission mechanism mounted on the frame. Multiple centralized transmission units are mounted on the frame and are connected to the main transmission mechanism. At least three centralized transmission units are connected to multiple independent transmission units along their respective length directions. The lower part of each independent transmission unit is engaged with the power output component of the centralized transmission unit, and the upper part of each independent transmission unit is connected to a conveying element. Multiple conveying elements perpendicular to the glass conveying direction form a conveying group, and multiple conveying groups along the glass conveying direction together form a conveying surface. The power of the main transmission mechanism is transmitted to the multiple independent transmission units connected to it via the centralized transmission units, and then the independent transmission units drive the connected conveying elements to rotate. A lifting mechanism is also connected below the centralized transmission unit to individually control the height of each centralized transmission unit in order to adjust the shape of the conveying surface.

[0005] Its beneficial effects are as follows: This conveying system, through a four-stage transmission setup consisting of a main drive mechanism, a centralized drive unit, independent drive units, and conveying elements, enables the modular assembly of conveying elements. It allows control over the position of each conveying element and the posture of each conveying group, thus forming a conveying surface of a specific shape from multiple conveying groups. When the shape or size of the glass to be conveyed changes, different conveying surfaces can be formed by selecting the centralized drive unit that needs to be connected to the independent drive unit, adjusting the position of the independent drive unit in the glass conveying direction, changing the specifications and number of conveying elements, and controlling the lifting and lowering of the centralized drive unit. This facilitates replacement and adjustment. Furthermore, the lower part of the independent drive unit meshes with the power output component of the centralized drive unit, making the replacement, position adjustment, and power input of the independent drive unit more convenient. The conveying system has a more ingenious structure and more stable power transmission. The specifications of the conveying elements include the length and diameter of the roller track, the number of rollers, and the diameter of the rollers.

[0006] Furthermore, the centralized transmission unit includes a support tube, a power output component mounted on the support tube, and a transmission tensioning mechanism. The power output component in the power output component and the strip-type transmission component in the transmission tensioning mechanism are connected together on a common transmission component, and the strip-type transmission component is also meshed with the active transmission wheel on the active transmission mechanism. Its beneficial effect is that the shared transmission assembly can connect the transmission tensioning mechanism and the power output assembly to realize the power transmission of the main transmission mechanism.

[0007] Furthermore, the transmission tensioning mechanism also includes a linear telescopic mechanism, a slider, a slide rail, and a first tensioning wheel. The belt-type transmission component is meshed with the first tensioning wheel. The first tensioning wheel is rotatably mounted on the slider. The slider slides along the slide rail. The slide rail and the linear telescopic mechanism are both fixed to the lower surface of the support tube. The telescopic end of the linear telescopic mechanism is hinged to the slider.

[0008] Its beneficial effects are: the shared transmission assembly can connect the transmission tensioning mechanism and the power output assembly to realize the power transmission of the main transmission mechanism; the transmission tensioning mechanism can control the position of the tensioning wheel so that the belt transmission component can still be tensioned after the centralized transmission unit is raised or lowered, thus ensuring the stable and reliable power transmission, thereby realizing the transmission of power from the main transmission mechanism to multiple centralized transmission units with different lifting heights.

[0009] Furthermore, a first reversing wheel is provided below the support tube. The first reversing wheel is located on one side of the meshing position between the belt drive component and the drive wheel, and is used to mesh with the lower layer of the belt drive component.

[0010] Its beneficial effect is that the first reversing wheel can ensure that the belt-type transmission component meshes better with the active transmission wheel.

[0011] Furthermore, the active transmission mechanism includes a drive motor and a main transmission shaft. The length of the main transmission shaft is perpendicular to the length direction of the centralized transmission unit, and the active transmission wheel on the main transmission shaft is connected to the centralized transmission unit one-to-one.

[0012] Its beneficial effect is that it can realize the power transmission of one main transmission mechanism to multiple centralized transmission units.

[0013] Furthermore, the independent transmission unit includes a mounting plate, a lower shaft, a lower transmission wheel, a meshing transmission wheel, an upper shaft, and an upper transmission wheel. The lower shaft is rotatably mounted on the lower part of the mounting plate, and the meshing transmission wheel and the lower transmission wheel are fixedly connected to the lower shaft. The upper shaft is rotatably mounted on the upper part of the mounting plate, and the upper transmission wheel is fixedly mounted on one end of the upper shaft. The other end of the upper shaft is connected to the conveying element. The upper transmission wheel and the lower transmission wheel are connected by a transmission belt. The lower part of the meshing transmission wheel is meshed with the power output component of the power output assembly on the centralized transmission unit to realize the access of power.

[0014] Its beneficial effects are: the independent transmission unit can be installed on the corresponding centralized transmission unit as needed, and is easy and flexible to disassemble and assemble. After installation, the lower part of the meshing transmission wheel meshes with the power output component of the power output assembly of the centralized transmission unit to ensure stable and reliable power transmission.

[0015] Furthermore, the mounting plate is also provided with a second tensioning mechanism, which includes a spring, a rocker arm assembly, and a second tensioning wheel. The rocker arm assembly includes a first rocker arm, a connecting shaft, and a second rocker arm. The upper end of the spring is fixed to the mounting plate, and the lower end of the spring is connected to the movable end of the first rocker arm. The fixed end of the first rocker arm is fixedly connected to the connecting shaft that passes through the mounting plate. The other end of the connecting shaft is fixedly connected to the fixed end of the second rocker arm located on the other side of the mounting plate. The movable end of the second rocker arm is fixedly connected to the axle of the second tensioning wheel.

[0016] Its beneficial effects are: the second tensioning mechanism uses a spring and rocker arm assembly to enable the second tensioning pulley to maintain a suitable pressure on the transmission belt, ensuring reliable power transmission to the upper transmission pulley.

[0017] The conveying element is a roller or a roller conveyor. When the conveying element is a roller conveyor, one end of the roller conveyor is connected to the corresponding independent transmission unit, and the other end is connected to a fixed bracket. The lower end of the fixed bracket is fixed on the corresponding centralized transmission unit. When the conveying element is a roller, each roller is connected to the corresponding independent transmission unit.

[0018] Its advantages are: it provides two specific structures for conveying elements; rollers require less installation space than roller conveyors; the adjustment of the conveying surface is more flexible; and more complex conveying surfaces can be formed. Therefore, the appropriate conveying element can be selected according to the actual situation.

[0019] Furthermore, at least one of the conveyor groups comprises three of the roller conveyors.

[0020] Its beneficial effects are: it provides a specific structural option for the conveyor group, with fewer components and simpler posture adjustment of the conveyor group.

[0021] Furthermore, at least one conveying group includes rollers and roller conveyors, with the roller conveyor located in the middle of the conveying group and arranged horizontally, and multiple rollers arranged on both sides of the roller conveyor along its length.

[0022] Its advantages are: it provides a specific structural option for the conveyor group, which is composed of multiple rollers and roller conveyors, making it suitable for use in situations with limited space, and the shape of the conveyor surface can also be adjusted more flexibly and complexly.

[0023] Furthermore, at least one conveying element in the conveying group is the roller mentioned above.

[0024] Its advantages are: it provides a specific structural option for the conveyor group, which is composed of multiple rollers, making it suitable for use in situations where space is limited, and the shape of the conveyor surface can also be adjusted more flexibly and complexly.

[0025] Furthermore, at least two roller conveyors located at both ends of the conveyor group are tiltable drive roller conveyors. The tiltable drive roller conveyor includes a roller body and an intermediate shaft disposed within the roller body. One end of the intermediate shaft is disposed within the roller body and connected to the roller body via a bearing. The other end of the intermediate shaft is machined into a ball head and extends out of one end of the roller body. The other end of the roller body is connected to the universal drive assembly.

[0026] Its beneficial effects are: while ensuring the tilting rotation of the roller conveyor, the intermediate shaft can remain relatively stationary, thus avoiding wear between the intermediate shaft and the fixed support and extending the service life of the roller conveyor.

[0027] Furthermore, the frame is provided with two conveying surfaces, which are arranged at intervals along the glass conveying direction.

[0028] Its beneficial effects are: of the two conveying surfaces, the first conveying surface can receive the pre-bent glass and, through cooperation with the second conveying surface, send the glass to a hollow mold that is larger than the second conveying surface. The hollow mold then transfers the glass to the next process to complete the subsequent processing.

[0029] The beneficial effects of this utility model are as follows: Through a four-stage transmission system consisting of a main transmission mechanism, a centralized transmission unit, independent transmission units, and conveying elements, this utility model enables the assembly of conveying elements in a modular fashion. It allows control over the position of each conveying element and the posture of each conveying group, thereby forming a conveying surface of a specific shape from multiple conveying groups. When the shape or size of the glass to be conveyed changes, different conveying surfaces can be formed by selecting a centralized transmission unit connected to an independent transmission unit, adjusting the position of the independent transmission unit in the glass conveying direction, adjusting the specifications and quantity of the conveying elements, and controlling the lifting and lowering of the centralized transmission unit. This facilitates replacement and adjustment. The conveying system has a more ingenious structure and more stable power transmission. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0032] Example 1 See attached document Figure 1-3 As shown, an adjustable glass conveying system includes a frame 5 and a centralized transmission unit 1, independent transmission units 2, conveying elements 3, and a main transmission mechanism 4 mounted on the frame 5. The main transmission mechanism 4 is the power source of the conveying system. There are multiple centralized transmission units 1, and multiple independent transmission units 2 are connected to selected centralized transmission units 1 according to the conveying needs. The independent transmission units 2 are connected to the conveying elements 3. The power of the main transmission mechanism 4 is transmitted to the multiple independent transmission units 2 connected to it through the centralized transmission units 1, and then the independent transmission units 2 drive the connected conveying elements 3 to rotate, thereby realizing the conveying of glass.

[0033] Specifically, at least three centralized transmission units 1 are connected to multiple independent transmission units 2 along their respective length directions. Each independent transmission unit 2 is connected to a conveying element 3. Multiple conveying elements 3 perpendicular to the glass conveying direction form a conveying group, and multiple conveying groups along the glass conveying direction together form a conveying surface. Each centralized transmission unit 1 is equipped with a lifting mechanism 6 at its lower part, which can realize independent lifting control of each centralized transmission unit 1. By controlling the multiple centralized transmission units 1 to lift and lower to a specific height, the position of the conveying element 3 and the posture of the conveying group are controlled, so that the multiple conveying groups form a conveying surface of a specific shape.

[0034] In this embodiment, there are 10 or 20 centralized transmission units, with 3 of these centralized transmission units each connected to multiple independent transmission units. Alternatively, there are 20 centralized transmission units, with 8 of these centralized transmission units each connected to multiple independent transmission units. Specifically, the number of centralized transmission units can be designed based on the range of glass sizes being transported, and the number and position of the centralized transmission units connected to the independent transmission units can be selected based on the size of the glass being transported.

[0035] like Figure 2 As shown, the centralized transmission unit 1 includes a support tube 10, a power output assembly 13, and a transmission tensioning mechanism 11. The support tube 10 is a hollow square tube. The power output assembly 13 includes two transmission wheels and a power output component connected to the two transmission wheels. The two transmission wheels are located at both ends of the support tube 10. The upper layer of the power output component is located above the support tube 10, and the lower layer of the power output component is connected to a common transmission assembly 12 below the support tube 10 via two second reversing wheels 14 disposed within the support tube 10. The common transmission assembly 12 is a double-row transmission wheel assembly, or two transmission wheels mounted on a single shaft.

[0036] The transmission tensioning mechanism 11 is used to stably transmit the power of the main transmission mechanism 4 to the corresponding power output component 13. The transmission tensioning mechanism 11 is located below the support tube 10 and includes a linear telescopic mechanism 111, a slider 112, a belt drive component 113, a first reversing wheel 114, a slide rail 115, and a first tensioning wheel 116. One end of the belt drive component 113 is connected to the common transmission component 12, and the other end is connected to the first tensioning wheel 116. The first tensioning wheel 116 is rotatably mounted on the slider 112, and the slider 112 is slidably mounted on the slide rail 115. The slide rail 115 and the linear telescopic mechanism 111 are both fixed to the lower surface of the support tube 10. The telescopic end of the linear telescopic mechanism 10 is hinged to the slider 112 to drive the slider 112 to move along the slide rail 115, thereby controlling the tension of the belt drive component 113 and facilitating power transmission. The first reversing wheel 114 engages with the lower layer of the belt drive 113, so that the belt drive 113 can engage with the drive wheel on the main drive shaft in the main drive mechanism 4. Figure 2 (at point A in the diagram), thereby enabling the power of the main transmission mechanism 4 to be transmitted to the common transmission assembly 12 via the belt transmission component 113, and then to the power output assembly 13.

[0037] With the adoption of the transmission tensioning mechanism 11, when the centralized transmission unit 1 is raised to different heights, the linear telescopic mechanism 111 can be controlled to drive the slider 112 to slide, maintaining the tension on the belt transmission component 113, and ensuring that the power is stably and reliably transmitted to the power output component 13.

[0038] Specifically, the linear telescopic mechanism 111 is a cylinder, hydraulic cylinder, or electric push rod, etc.; the belt drive component 113 is a chain; the power output component 13 is a chain drive component; correspondingly, the first tensioning pulley 116, the first reversing pulley 114, and the second reversing pulley 14 are all sprockets; the common transmission component 12 is a double-row sprocket, or the common transmission component 12 is two single-row sprockets mounted on the same shaft. Similarly, the belt drive component 113 is a synchronous belt; the power output component 13 is a synchronous belt drive component; correspondingly, the first tensioning pulley 116, the first reversing pulley 114, and the second reversing pulley 14 are all synchronous belt pulleys; the common transmission component 12 is a double-row pulley, or the common transmission component 12 is two single-row pulleys mounted on the same shaft.

[0039] The main transmission mechanism 4 includes a drive motor and a main transmission shaft 41. One end of the main transmission shaft 41 is connected to the drive motor, and the other end is rotatably supported on the frame 5. The main transmission shaft 41 is equipped with active transmission wheels 42, each corresponding to a centralized transmission unit 1. The active transmission wheels 42 are engaged with the belt-type transmission component 113 and connected to the transmission tensioning mechanism 11, thereby driving the power output component 13 on the centralized transmission unit 1. Therefore, one main transmission mechanism 4 can simultaneously transmit power to multiple centralized transmission units 1, driving the corresponding power output components 13. Furthermore, multiple centralized transmission units 1 with different lifting heights can engage more securely with the main transmission mechanism 4 through their corresponding transmission tensioning mechanisms 11, ensuring stable and reliable power transmission.

[0040] like Figure 3 As shown, the independent transmission unit 2 includes a mounting plate 20, a lower shaft 21, a lower transmission wheel 22, a meshing transmission wheel 23, an upper shaft 24, and an upper transmission wheel 25. The lower shaft 21 is rotatably mounted on the lower part of the mounting plate 20. The meshing transmission wheel 23 and the lower transmission wheel 22 are fixedly mounted on the lower shaft 21. The meshing transmission wheel 23 and the lower transmission wheel 22 can be located on the same side of the mounting plate 20 or on opposite sides of the mounting plate 20. The upper shaft 25 is rotatably mounted on the upper part of the mounting plate 20. The upper transmission wheel 24 is fixedly mounted on one end of the upper shaft 25, and the other end of the upper shaft 25 is connected to the conveying element 3. The upper transmission wheel 24 and the lower transmission wheel 22 are connected by a transmission belt. The lower end of the mounting plate 20 is fixed to the support tube 10 of the corresponding centralized transmission unit 1 with screws. After the mounting plate 20 is fixed to the centralized transmission unit 1, the lower part of the meshing transmission wheel 23 meshes with the power output component of the power output assembly 13 of the centralized transmission unit 1, realizing power access. Therefore, the required number of independent transmission units 2 can be selected and installed on the centralized transmission unit 1 as needed. After the independent transmission units 2 are installed, power can be transmitted from the centralized transmission unit 1 to the independent transmission units 2. The structure is simple and the power access is stable. The transmission belt in the independent transmission unit 2 is a chain or synchronous belt, and the upper transmission wheel 24 and the lower transmission wheel 22 are selected as sprockets or pulleys.

[0041] The conveying element 3 is a roller conveyor or a roller wheel. For example... Figure 1As shown, in this embodiment, the conveying element 3 is a roller conveyor 31. Each conveying group includes three roller conveyors 31. Each roller conveyor 31 has a fixed support and an independent transmission unit 2 at both ends. The lower ends of the fixed support and the independent transmission unit 2 are connected to the support pipe 10 of the corresponding centralized transmission unit 1. By adjusting the lifting height of the connected centralized transmission unit 1 through the lifting mechanism 6, the tilt angle of the two roller conveyors 31 on both sides of the conveying group can be adjusted. Preferably, the lifting mechanism 6 only needs to control the lifting of the centralized transmission unit 1 corresponding to the outer ends of the two roller conveyors 31 on both sides of the conveying group to achieve the adjustment of the tilt angle, so that multiple conveying groups form a conveying surface of a specific shape, such as a "︺" conveying surface. This conveying group has fewer components and is easy to adjust. Alternatively, the conveying group can also be composed of more than three roller conveyors 31. In this example, the total number of centralized transmission units 1 is greater than the number of centralized transmission units 1 connected to independent transmission units 2, which facilitates the adjustment of the centralized transmission units and their positions, as well as the specifications of the roller conveyors 31, thereby achieving the adjustment of the shape of the conveying surface.

[0042] When the conveying element 3 uses a roller conveyor 31, both ends of the roller conveyor 31 are connected to the corresponding independent transmission unit 2 and a fixed support to ensure that the roller conveyor 31 can stably transmit power and rotate smoothly. In some embodiments, one end of the roller conveyor 31 is connected to the independent transmission unit 2 through a universal joint assembly, and the other end is connected to the fixed support through a ball joint structure or universal joint assembly, which can ensure stable power transmission when the roller conveyor 31 is tilted. The universal joint assembly is two connected universal joint forks, or a ball cage coupling. Regardless of the connection method, the end of the roller conveyor 31 connected to the fixed support is the driven end and does not need to be connected to power.

[0043] In this embodiment, each independent transmission unit 2 is connected to one conveying element 3. In other embodiments, at least one independent transmission unit 2 may be connected to two or three conveying elements 3. When an independent transmission unit is connected to multiple conveying elements, the lower part of the independent transmission unit is provided with a lower shaft 21, and the upper part is provided with multiple upper shafts 25. Each upper shaft 25 is connected to the conveying element 3 and the upper transmission wheel 24 at both ends, and the multiple upper transmission wheels 24 and a lower transmission wheel 22 are connected by a transmission belt.

[0044] In this embodiment, the lifting mechanism 6 controls the connected centralized transmission unit 1 to lift and lower at different heights to adjust the conveying surface. After adjustment, the main transmission mechanism 4 can transmit power to multiple centralized transmission units 1 with different lifting levels. The centralized transmission unit 1 transmits power to multiple independent transmission units 2 fixed on it. The independent transmission units 2 transmit power to the conveying element 3 to realize the conveying of the glass on the conveying surface.

[0045] This utility model is used in the process of forming automotive windshields to receive curved glass from a glass pre-bending furnace and place the curved glass on a hollow mold. The conveying surface is smaller than the curved glass, and the conveying surface moves up and down relative to the hollow mold at the hollow position of the hollow mold so as to place the curved glass on the hollow mold.

[0046] Example 2 Based on Embodiment 1, the independent transmission unit 2 in this embodiment further includes a second tensioning mechanism, which is used to maintain the tension of the transmission belt between the upper transmission wheel and the lower transmission wheel to ensure stable power transmission.

[0047] like Figure 4 , 5 As shown, the second tensioning mechanism includes a spring 261, a rocker arm assembly, and a second tensioning wheel 262. The rocker arm assembly includes a first rocker arm 263, a connecting shaft 264, and a second rocker arm 265. The spring 261 is in a stretched state, with its upper end fixed to one side of the mounting plate 20. The lower end of the spring 261 is connected to the movable end of the first rocker arm 263. The fixed end of the first rocker arm 263 is fixedly connected to one end of the connecting shaft 264, which passes through the mounting plate 20. The other end of the connecting shaft 264 is fixedly connected to the fixed end of the second rocker arm 265, which is located on the other side of the mounting plate 20. The movable end of the second rocker arm 265 is fixedly connected to the second tensioning wheel 262. The spring 261 and the rocker arm assembly are used to ensure that the second tensioning wheel 262 maintains a suitable pressure on the transmission belt. It should be noted that the "movable end" refers to the end that can swing relative to the belt, while the "fixed end" refers to the end that can only rotate around the connected shaft 264 and cannot swing.

[0048] In other embodiments, unlike in Embodiment 2 where the lower transmission wheel 22 and the meshing transmission wheel 23 are respectively arranged on both sides of the mounting plate 20, the lower transmission wheel 22 and the meshing transmission wheel 23 can be arranged on the same side of the mounting plate 20, which can also realize the transmission of power.

[0049] Example 3 Based on Example 1 or 2, such as Figure 6 As shown, at least one of the conveying groups includes several roller conveyors 31 and several rollers 32. Preferably, the roller conveyors 31 are horizontally arranged and located in the middle of the conveying group. The two ends of the roller conveyors 31 are respectively connected to a fixed support and an independent transmission unit 2. Several rollers 32 are arranged on both sides of the length direction of the roller conveyors 31. Each roller 32 is connected to an independent transmission unit 2. Several roller conveyors 31 and several rollers 32 can jointly form a conveying group that can form a specific posture. The multiple conveying groups form a conveying surface of a specific shape, such as a conveying surface of “︺”.

[0050] In this embodiment, there may be one or more roller conveyors 31, which can be determined according to the size of the glass being conveyed or the length of the roller conveyor 31.

[0051] In this embodiment, a conveying group is formed by multiple rollers 32 and roller conveyors 31, which is suitable for use in situations where space is limited, and the shape of the conveying surface can also be adjusted more flexibly and complexly.

[0052] In other embodiments, the positions of the roller conveyor 31 and roller 32 within the conveyor group can be adjusted and combined according to actual conditions.

[0053] In this embodiment, all conveying groups in the conveying system adopt the structure described in this example, that is, the conveying group includes a plurality of roller conveyors 31 and a plurality of rollers 32. In other embodiments, some conveying groups in the conveying system adopt the structure described in this example, while other conveying groups adopt the structure of Embodiment 1.

[0054] Example 4 Based on embodiment 1 or 2, at least one of the conveying groups comprises multiple conveying elements, each of which is a roller 32. Each roller 32 is connected to an independent transmission unit 2. The multiple rollers 32, through the lifting and lowering of their connected centralized transmission unit 1, cause the conveying group to assume a specific posture. The multiple conveying groups form a conveying surface of a specific shape, such as a conveying surface in the shape of a "︺". Using multiple rollers 32 to form a conveying group is suitable for use in situations with limited space, and the shape of the conveying surface can be adjusted more flexibly and complexly.

[0055] In this embodiment, all conveying groups in the conveying system adopt the structure described in this example, that is, the conveying group includes multiple rollers 32. In other embodiments, some conveying groups in the conveying system adopt the structure of this example, while other conveying groups adopt the structure of Embodiment 1 and / or Embodiment 2.

[0056] Example 5 In the above embodiments 1-4, the conveying system is provided with one conveying surface. In this embodiment, two conveying surfaces can be provided in the conveying system. The conveying surface near the glass pre-bending furnace is used to receive the glass pre-bent by the glass pre-bending furnace and send it to the other conveying surface. The other conveying surface is located in the lower mold hollow position of the mold trolley and is used to place the glass being carried on the lower mold.

[0057] The two conveying surfaces in this embodiment can be composed of any of the conveying surfaces described in embodiments 1-4 above, in order to meet the application requirements of different usage scenarios.

[0058] Example 6 In the above embodiments, when the conveying element is a roller conveyor 31, at least the power end of the roller conveyor 31 is connected to the independent transmission unit 2 through a universal joint mechanism, and the driven end is connected to the fixed support through a ball joint structure. With prolonged use of the roller conveyor 31, wear will occur between the ball joint structure and the fixed support, affecting the shape accuracy of the conveying surface and the stability of the roller conveyor 31's rotation.

[0059] To address this issue, this embodiment proposes further improvements to the structure of the roller conveyor 31. Specifically, as follows... Figure 7 As shown, roller conveyor 31 is a tiltable drive roller conveyor, which includes a roller body 310, a universal drive assembly 311, and an intermediate shaft 312. One end of the intermediate shaft 312 is disposed inside the roller body 310 and rotates relative to the roller body 310 via a bearing 313, while the other end extends from one end of the roller body 310 and is machined into a ball head. The inner end of the universal drive assembly 311 is embedded inside the other end of the roller body 310. This roller conveyor 31 can drive the roller body 310 to rotate via the universal drive assembly 311, while the intermediate shaft 312 does not rotate, thus satisfying the installation and rotation of tiltable drive roller conveyors at different tilt levels. Moreover, the intermediate shaft 312 does not wear under long-term use in a tilted posture, and the structure is simple and durable.

[0060] Specifically, one end of the tiltable drive roller conveyor is connected to the independent drive unit 2 via a universal joint assembly 311, and the other end is connected to the fixed support via the ball joint of its intermediate shaft 312. The fixed support is provided with a spherical space structure, such as a ball socket, to accommodate the ball joint. More specifically, the universal joint assembly 311 is a universal joint assembly, including two universal joint forks that are mated together.
