Description

Technical Field

[0001] This invention relates to the field of automated conveying equipment technology, specifically a modular high-speed chain conveying system. Background Technology

[0002] In automated production lines, double-speed chains have been widely used due to their excellent continuous conveying capacity and load-bearing performance. However, traditional double-speed chain conveying devices usually integrate the driving sprocket, driven sprocket, and conveyor chain into one unit. For example, patent CN1055110146B discloses a modular double-speed chain conveyor belt, which has a rotating shaft inside a protective cover at one end. The driving sprocket is clamped onto the rotating shaft and connected to the drive motor. The other end of the protective cover contains a driven sprocket, tensioning device, guide wheel, guide block, and other structures. However, this traditional integrated speed-multiplying chain module structure is not flexible enough, especially since the width of the speed-multiplying chains on both sides of the module is usually fixed. Therefore, it can generally only be used on specific production lines. In addition, since the driven sprockets at the end are usually fixed on the same shaft, when the chain becomes uneven in tension or deviates due to installation errors, uneven wear, or load offset, it can generally only be adjusted by using additional tension sprockets or other mechanisms, such as the tensioning device in patent CN1055110146B. This device includes clamping bolts, tensioning blocks, and other structures. However, this also makes the speed-multiplying chain module structure complex, and adjusting the tension in a confined space is relatively laborious. Summary of the Invention

[0003] The purpose of this invention is to provide a split modular double-speed chain transmission system, in which the active module can adjust the distance between the two active sprockets as needed, while the driven module can adjust the distance between the two driven sprockets. Furthermore, the driven sprockets can also achieve axial and radial fine-tuning to ensure the tension and normal operation of the double-speed chain.

[0004] The objective of this invention is achieved through the following technical solution: A modular, multi-speed chain transmission system includes an active module and a driven module.

[0006] The upper end of the first base is provided with a first adjustment component, which includes a first lead screw and a first adjustment device. The two ends of the first lead screw are rotatably mounted on both sides of the upper end of the first base by bearing support. The first adjustment device is located on the outside of the first base, and the first lead screw is driven to rotate by the first adjustment device. The first lead screw is provided with two first lead screw sections with opposite rotation directions. The lower end of the first adjustment slide is provided with a first lead screw nut, and the first lead screw nut is fitted onto the first lead screw section on the corresponding side.

[0007] The drive shaft includes a first shaft segment and a second shaft segment. The first shaft segment includes a sprocket mounting part and an insertion part. The drive sprocket on the corresponding side of the first shaft segment is fitted onto the free end of the sprocket mounting part. The second shaft segment has an insertion hole inside, and the insertion part is inserted into the insertion hole. The inner wall of the insertion hole has a keyway, and the outer wall of the insertion part has a sliding key, and the sliding key is placed in the corresponding keyway.

[0008] The sprocket mounting portion of the first shaft segment has the same diameter as the second shaft segment.

[0009] The upper end of the second base is provided with a second adjustment component, which includes a second lead screw and a second adjustment device. The two ends of the second lead screw are rotatably mounted on both sides of the upper end of the second base by bearing support. The second adjustment device is located on the outside of the second base, and the second lead screw is driven to rotate by the second adjustment device. The second lead screw is provided with two sections of the second lead screw with opposite rotation directions. The lower end of the second adjustment slide is provided with a second lead screw nut, and the second lead screw nut is fitted onto the corresponding section of the second lead screw.

[0010] The driven sprocket assembly includes a driven sprocket, a mounting base, an adjusting sleeve, and an axial adjusting shaft. The mounting base has an adjusting groove, and the adjusting sleeve includes an internally threaded sleeve portion disposed in the adjusting groove. One end of the internally threaded sleeve portion has a first limiting plate that contacts one side of the outer wall of the mounting base, and the other end has a second limiting plate that contacts the other side of the outer wall of the mounting base. The axial adjusting shaft includes a smooth shaft portion and a threaded portion. The driven sprocket is rotatably mounted on the smooth shaft portion, and the threaded portion passes through the internally threaded sleeve portion.

[0013] The mounting base is provided with a fixed base plate at its lower end, and the fixed base plate is provided with mounting holes at both ends for connecting to the second adjusting slide plate on the corresponding side.

[0014] The advantages and positive effects of this invention are as follows: 1.

[0015] 2. When installing the double-speed chain or after each width adjustment, the driven sprocket can be used for axial and radial fine-tuning to ensure the tension of the double-speed chain. After the installation of the double-speed chain or each width adjustment is completed, a test run of the double-speed chain is required. If the chain is found to be off-track, the driven sprocket can also be used for timely adjustment to ensure the normal operation of the double-speed chain.

[0016] 3. The present invention separates the active module and the driven module, which can adapt to different transmission lengths. In addition, the width of both the active sprocket and the driven sprocket can be adjusted, which can further improve the flexibility and applicability of the present invention. At the same time, the present invention uses the independently set driven sprocket at the end to fine-tune and ensure the tension of the double speed chain, which simplifies the structure and makes adjustment more convenient.

Detailed Implementation

[0019] The invention will now be described in further detail with reference to the accompanying drawings.

[0020] like Figures 1-7 As shown, the present invention includes an active module and a passive module, wherein, as Figure 1 As shown, the active module has adjustable first adjustment slide plates 2 on both sides of its upper end and a double-speed chain drive assembly in the middle. The double-speed chain drive assembly includes a telescopically adjustable drive shaft 6, and the two ends of the drive shaft 6 are respectively supported by bearing seats and rotatably mounted on the corresponding first adjustment slide plates 2. Drive sprockets 7 are provided at both ends of the drive shaft 6. Figure 4As shown, the driven module has two movable and adjustable second adjustment slide plates 10 on its upper sides, and the second adjustment slide plates 10 are equipped with driven sprocket assemblies 11. The driven sprocket assembly 11 includes a driven sprocket 1101 with two degrees of freedom of adjustment, axial and radial. One end of the speed-multiplying chain is fitted onto the corresponding driving sprocket 7, and the other end is fitted onto the corresponding driven sprocket 1101. When the invention is working, the first adjustment slide plates 2 on both sides of the driving module can open and close according to actual needs, thereby adjusting the width of the driving sprockets 7 on both sides. At the same time, the drive shaft 6 can extend and retract in coordination, and the second adjustment slide plates 10 on both sides of the driven module open and close synchronously, thereby adjusting the width of the driven sprockets 1101 on both sides, that is, realizing the width adjustment of the speed-multiplying chain on both sides. After the width adjustment of the double-speed chain is completed, the driven sprocket 1101 ensures the tension of the double-speed chain on both sides by axial or radial fine adjustment. If deviation or other issues are found during the trial operation of the double-speed chain, timely adjustment can also be made by axial or radial fine adjustment of the driven sprocket 1101, thereby ensuring the normal operation of the double-speed chain.

[0021] like Figure 1 As shown, in this embodiment, the active module includes a first base 1, and a fixed support plate 101 is provided at the upper center of the first base 1. The speed-multiplying chain drive assembly is disposed on the fixed support plate 101. In this embodiment, the speed-multiplying chain drive assembly includes a speed-multiplying chain drive device 4 and a transmission sprocket assembly 5, wherein the transmission sprocket assembly 5 includes a first transmission sprocket, a second transmission sprocket, and a transmission chain. The first transmission sprocket is mounted on the output shaft of the speed-multiplying chain drive device 4, the second transmission sprocket is mounted on the drive shaft 6, and the first and second transmission sprockets are connected by the transmission chain. In this embodiment, the speed-multiplying chain drive device 4 may be a geared servo motor.

[0022] like Figure 1 As shown, in this embodiment, the first base 1 has a first sliding support beam on the front and rear sides of its upper end, and a first linear slide rail on the first sliding support beam. The lower surfaces of the first adjusting slide plate 2 on both sides are provided with a first linear slider, and the first linear slider cooperates with the first linear slide rail on the corresponding side to realize the sliding connection between the first adjusting slide plate 2 and the first base 1. The front and rear ends of the fixed support plate 101 can be fixed to the first sliding support beam on the corresponding side respectively.

[0023] like Figure 1As shown, the upper end of the first base 1 is provided with a first adjustment component 3. In this embodiment, the first adjustment component 3 includes a first lead screw 302 and a first adjustment device 301. The two ends of the first lead screw 302 are rotatably mounted on both sides of the upper end of the first base 1 by bearing support. The first adjustment device 301 is located on the outside of the first base 1, and the first lead screw 302 is driven to rotate by the first adjustment device 301. The first lead screw 302 has two first lead screw segments with opposite rotation directions. The lower end of the first adjustment slide plate 2 is provided with a first lead screw nut, and the first lead screw nut is fitted onto the corresponding first lead screw segment. Since the two first lead screw segments on the first lead screw 302 have opposite rotation directions, when the first adjustment device 301 drives the first lead screw 302 to rotate, the first lead screw 302 drives the first adjustment slide plates 2 on both sides to open and close. In this embodiment, the first adjustment device 301 can be a geared servo motor.

[0024] like Figures 1-3 As shown, in this embodiment, the drive shaft 6 includes a first shaft segment 601 and a second shaft segment 602. The first shaft segment 601 includes a sprocket mounting portion 6011 and an insertion portion 6012. The drive sprocket 7 on the corresponding side of the first shaft segment 601 is fitted onto the free end of the sprocket mounting portion 6011. The second shaft segment 602 has an insertion hole inside, and the insertion portion 6012 is inserted into the insertion hole. Figure 3 As shown, keyways are evenly distributed along the circumferential direction on the inner wall of the insertion hole, and sliding keys 6013 are evenly distributed along the circumferential direction on the insertion part 6012. The sliding keys 6013 are respectively placed in the corresponding keyways and can realize the relative sliding between the insertion part 6012 and the second shaft segment 602.

[0025] This invention first requires ensuring that the insertion part 6012 has a sufficient diameter and a sufficient length for insertion and mating. This is to ensure that when the second adjusting slide plates 2 on both sides are opened to their maximum distance, the first shaft segment 601 and the second shaft segment 602 remain in the insertion state. It also ensures that the overall support strength of the drive shaft 6 meets the driving requirements of the double-speed chain. Secondly, regardless of how the drive shaft 6 extends or retracts, the first shaft segment 601 and the second shaft segment 602 can always maintain synchronous rotation through the sliding key 6013 and the keyway, thereby ensuring synchronous rotation of the drive sprockets 7 on both sides. Furthermore... Figure 2 As shown, the sprocket mounting portion 6011 of the first shaft segment 601 of the present invention has the same diameter as the second shaft segment 602. This ensures that the drive sprockets 7 on both sides have the same mounting dimensions, eliminating the need for sprockets with different inner diameters. Furthermore, as... Figure 1As shown, in this embodiment, the second transmission sprocket in the transmission sprocket assembly 5 is mounted on the second shaft segment 602, and the fixed support plate 101 can be configured with an auxiliary support slide to support the second shaft segment 602 according to actual needs.

[0026] like Figure 4 As shown, in this embodiment, the driven module includes a second base 8, and the upper end of the second base 8 is provided with a second sliding support beam 801 on both the front and rear sides. The second sliding support beam 801 is provided with a second linear slide rail. The second adjusting slide plate 10 is provided with a second linear slider on both sides, and the second linear slider cooperates with the second linear slide rail on the corresponding side, thereby realizing the sliding connection between the second adjusting slide plate 10 and the second base 8.

[0027] like Figure 4 As shown, the upper end of the second base 8 is provided with a second adjustment component 9. In this embodiment, the second adjustment component 9 includes a second lead screw 902 and a second adjustment device 901. The two ends of the second lead screw 902 are rotatably mounted on both sides of the upper end of the second base 8 by bearing support. The second adjustment device 901 is located on the outside of the second base 8, and the second lead screw 902 is driven to rotate by the second adjustment device 901. The second lead screw 902 has two sections with opposite rotation directions. The lower end of the second adjustment slide plate 10 is provided with a second nut, and the second nut is fitted onto the corresponding second lead screw section. Since the two sections of the second lead screw 902 have opposite rotation directions, when the second adjustment device 901 drives the second lead screw 902 to rotate, the second lead screw 902 drives the second adjustment slide plates 10 on both sides to open and close. In this embodiment, the second adjustment device 901 can be a geared servo motor.

[0028] like Figures 4-7 As shown, in this embodiment, the driven sprocket assembly 11 includes a driven sprocket 1101, a mounting base 1103, an adjusting sleeve 1104, and an axial adjusting shaft 1105. The mounting base 1103 has an adjusting groove 11031. The adjusting sleeve 1104 includes an internally threaded sleeve portion 11045, which is disposed in the adjusting groove 11031. One end of the internally threaded sleeve portion 11045 has a first limiting disc 11043 that contacts one side of the outer wall of the mounting base 1103, and the other end has a second limiting disc 11044 that contacts the other side of the outer wall of the mounting base 1103. The axial adjusting shaft 1105 includes a smooth shaft portion 11052 and a threaded portion. The driven sprocket 1101 is rotatably mounted on the smooth shaft portion 11052, and the threaded portion passes through the internally threaded sleeve portion 11045. Figure 7As shown, radial screws 11041 are provided on both sides of the internal thread sleeve portion 11045, and the radial screws 11041 pass through the groove wall on the corresponding side of the adjusting groove 11031 and are threadedly connected to the corresponding radial locking nut 11042.

[0029] like Figures 5-6 As shown, in this embodiment, the driven sprocket 1101 is rotatably mounted on the optical shaft portion 11052 of the axial adjustment shaft 1105 via a sprocket bearing 1102. The optical shaft portion 11052 has a shoulder, and one side of the driven sprocket 1101 is limited by the shoulder, while the other side is limited by a retaining ring 11011 mounted on the optical shaft portion 11052. After removing the retaining ring 11011 with a tool, driven sprockets 1101 of different diameters can be replaced as needed. The retaining ring 11011 is a known technology in the art. Furthermore, in this embodiment, the installation method of the driving sprocket 7 is the same as that of the driven sprocket 1101.

[0030] like Figures 5-6 As shown, in this embodiment, the threaded portion of the axial adjustment shaft 1105 is provided with a nut 11051 at the end away from the optical axis portion 11052 to facilitate screwing and adjustment.

[0031] like Figures 5-6 As shown, in this embodiment, the mounting base 1103 is provided with a fixed base plate 11032 at its lower end, and the fixed base plate 11032 is provided with mounting holes at both ends for fixed connection with the second adjusting slide plate 10 on the corresponding side. In this way, when the driven sprocket assembly 11 on one side fails, the mounting base 1103 as a whole can be disassembled and separated from the second adjusting slide plate 10 on the corresponding side and a new driven sprocket assembly 11 can be replaced.

[0032] The working principle of this invention is as follows: The installation of this invention includes the following steps: Step 1: Transport the first base 1 and the second base 8 to their respective positions on the automated production line by hoisting or other means. The first base 1 and the second base 8 are equipped with connecting seats and other structures to achieve a fixed connection with the adjacent production line frame, while ensuring the initial positioning of the two bases.

[0033] In addition, the present invention can be equipped with protective covers and other structures on each adjusting slide plate and on adjacent production line frames as needed, which is a well-known technology in the field.

[0034] Step 2: Adjust the distance between the first adjusting slide plates 2 on both sides of the upper end of the first base 1 and the distance between the second adjusting slide plates 10 on both sides of the upper end of the second base 8 according to the specific conditions of the automated production line.

[0035] Among them, such as Figure 1 and Figure 4As shown, in this step, the first adjusting device 301 and the second adjusting device 901, which complete the electrical circuit connection, can be controlled to operate synchronously by the control system, thereby realizing the synchronous opening and closing movement of the first adjusting slide plate 2 and the second adjusting slide plate 10. At the same time, the screw and nut cooperation can also ensure accurate control of the adjustment movement distance.

[0036] Other examples Figures 2-3 As shown, since the first shaft segment 601 and the second shaft segment 602 of the drive shaft 6 are plug-in, the drive shaft 6 can extend and retract when the first adjusting slide plates 2 on both sides move. At the same time, the plug-in part 6012 of the first shaft segment 601 is engaged with the keyway on the inner wall of the plug-in hole of the second shaft segment 602 through the sliding key 6013, thereby ensuring that the subsequent two drive sprockets 7 rotate synchronously.

[0037] Step 3: Install one end of the speed-multiplying chain onto the corresponding drive sprocket 7 and the other end onto the corresponding driven sprocket 1101.

[0038] In this step, firstly as follows Figures 5-7 As shown, the position of the internal threaded sleeve 11045 in the adjusting groove 11031 should ensure that the double speed chain can be smoothly fitted onto the driven sprocket 1101, but the double speed chain is not tensioned.

[0039] Secondly, during the installation of the double-speed chain, the operator can rotate the axial adjustment shaft 1105 to move the axial adjustment shaft 1105 relative to the internal threaded sleeve portion 11045, thereby fine-tuning the axial position of the driven sprocket 1101 to ensure the installation of the double-speed chain.

[0040] Step 4: Tighten the radial locking nut 11042 outward and fine-tune the position of the internal thread sleeve 11045 in the adjusting groove 11031, thereby fine-tuning the position of the driven sprocket 1101 to ensure the tension of the double speed chain.

[0041] Among them, such as Figure 6As shown, during fine-tuning, the operator can screw the radial locking nut 11042 on either side outwards without disengaging it from the corresponding radial screw 11041, or screw both radial locking nuts 11042 outwards without disengaging them from the radial screw 11041. This ensures that the internal threaded sleeve 11045 has a certain fine-tuning space within the adjusting groove 11031. Then, the operator pushes the driven sprocket 1101 to tension the double-speed chain. During this process, due to the limiting effect of the first limiting plate 11043 and the second limiting plate 11044, the adjusting sleeve 11... The internal threaded sleeve 11045 of 04 can only move and fine-tune along the adjusting groove 11031, thereby ensuring that the axial angle of the driven sprocket 1101 will not change. When the internal threaded sleeve 11045 moves into place, the operator supports the driven sprocket 1101 with one hand to keep the double-speed chain tensioned, and with the other hand, screws the radial locking nuts 11042 inward, so that the radial locking nuts 11042 on both sides re-clamp the mounting base 1103 to fix the position of the adjusting sleeve 1104, that is, to fix the position of the driven sprocket 1101.

[0042] Step 5: Start the automated production line for trial operation and observe the running trajectory of the double-speed chains on both sides. If the chain transmission is found to be off-track, stop the machine and adjust the driven sprocket 1101 axially by turning the axial adjustment shaft 1105, or adjust the driven sprocket 1101 radially by turning the radial locking nut 11042 so that the internal thread sleeve part 11045 drives the driven sprocket 1101.

[0043] In addition, after the above installation is completed, the width spacing of the two double speed chains can be adjusted according to actual needs in normal operation through step two above. After each width adjustment, the operator can make axial or radial fine adjustments to the driven sprocket 1101 to ensure the tension of the two double speed chains. After each adjustment, a test run of the double speed chain is required. If deviation is found, timely adjustment can be achieved through axial or radial fine adjustments of the driven sprocket 1101.
