It should be understood that the thickness, length, and other dimensions of various components in the embodiments of this application shown in the drawings, as well as the overall thickness, length, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0033] As part of the inventive concept of this application, before describing the embodiments of this application, it is necessary to analyze the reasons for the fault problem that the chain and sprocket are prone to disengagement during the operation of the conveying device in the related art, and obtain the technical solution of the embodiments of this application through reasonable analysis.

[0034] In related technologies, during the continuous production of chemical products such as water-reducing agents and polyethers, conveying devices are required to transport materials. (Refer to...) Figure 1 The existing conveying device includes a support 1 and multiple conveying rollers mounted on the support 1. The multiple conveying rollers are arranged sequentially along the conveying direction of the conveying device. Each conveying roller is equipped with two sprockets. When the sprockets rotate, they drive the conveying rollers to rotate.

[0035] A chain drive connects any two adjacent conveyor rollers along the conveying direction. Specifically, the two adjacent conveyor rollers are the first conveyor roller and the second conveyor roller. A sprocket on the first conveyor roller is connected to a sprocket on the second conveyor roller by a chain 4. The chain 4 meshes with the two sprockets. When one sprocket rotates, the chain 4 can drive the other sprocket to rotate synchronously.

[0036] One of the sprockets on the conveyor roller located at one end of the conveying direction is connected to the sprocket on the adjacent conveyor roller via chain 4, and the other sprocket is connected to the sprocket on the drive assembly via chain 4. The drive unit is used to provide power for the rotation of the sprockets.

[0037] Since a chain 4 is used to drive any two adjacent conveyor rollers, there are many chains 4 and sprockets, the transmission structure is complex and the reliability is poor. If any chain 4 fails, the machine needs to be stopped for maintenance. During the maintenance process, multiple conveyor rollers need to be disassembled and reassembled, and the maintenance time is long.

[0038] It should also be noted that the conveyor roller includes a cylinder and two roller shafts, which are located at opposite ends of the cylinder. The roller shafts are connected to the cylinder via bearings and can rotate relative to the cylinder. When the conveyor roller is mounted on a bracket, the bracket has grooves, and the roller shafts of the conveyor roller are placed in the grooves on the bracket from top to bottom, thus connecting the conveyor roller to the bracket.

[0039] Since the conveyor rollers are placed directly in the groove of the support, they will bounce up and down during operation. This bouncing can easily cause the sprocket to disengage from the chain 4, affecting the transmission between the conveyor rollers.

[0040] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0041] Reference Figure 2This application discloses a conveying device, including a support 1, a drive roller 2, a chain 4, and a plurality of conveying rollers. The plurality of conveying rollers are rotatably mounted on the support 1 about their own axes, and the plurality of conveying rollers are arranged sequentially along a first direction, which is the direction in which the conveying device conveys materials. The conveying roller includes a driving roller 2 and a plurality of driven rollers 3 arranged sequentially along a first direction. The driving roller 2 is provided with a driving sprocket 21, and each of the driven rollers 3 is provided with a driven sprocket 31. The chain 4 meshes with the drive sprocket 21 and the multiple driven sprockets 31, so that when the drive sprocket 21 rotates, it can drive the multiple driven sprockets 31 to rotate synchronously.

[0042] For ease of explanation, a first direction and a second direction are defined, where the first direction is the conveying direction of the conveying device, and also the length direction of the conveying device; the second direction is the width direction of the conveying device, and also the axial direction of the conveying roller. In the accompanying drawings, the first direction is represented by the X direction, and the second direction is represented by the Y direction.

[0043] For example, the support 1 is a frame placed on the ground, with its length along a first direction and its width along a second direction; the support 1 is used to support the driving roller 2 and the driven roller 3.

[0044] The axis of the conveying roller is arranged along the second direction, and the driving roller 2 and multiple driven rollers 3 included in the conveying roller are arranged sequentially along the first direction.

[0045] A drive sprocket 21, rotating synchronously with the drive roller 2, is fixed on the drive roller 2. A driven sprocket 31, rotating synchronously with the driven roller 3, is fixed on the driven roller 3. A chain 4 is sleeved on the drive sprocket 21 and the driven sprocket 31 of the end roller 32. (See figure) Figure 5 The end roller 32 is the driven roller 3 that is furthest from the driving roller 2 along the first direction on the same chain 4, and the chain 4 also meshes with other driven sprockets 31.

[0046] When the drive roller 2 rotates around itself, the drive sprocket 21 rotates, the chain 4 rotates synchronously, the chain 4 drives multiple driven sprockets 31 to rotate, and the driven sprockets 31 drive the corresponding driven rollers 3 to rotate synchronously, so that the material placed on the drive roller 2 and the driven rollers 3 is conveyed forward along the first direction.

[0047] In the prior art, two sprockets are set on the same conveyor roller, and two adjacent conveyor rollers arranged in sequence along the conveying direction are driven by a chain 4. There are many chains 4. When the number of conveyor rollers is N, the number of chains 4 is N-1. There are many meshing positions between the chain 4 and the sprocket, and the risk of failure due to failure at the chain 4 and the sprocket is high.

[0048] This application adopts a single chain 4 to directly drive the driving sprocket 21 and multiple driven sprockets 31, which simplifies the transmission structure, reduces the number of chains 4 and sprockets, and reduces the risk of failure caused by the failure of the connection between the chain 4, the driving sprocket 21 and the multiple driven sprockets 31, thereby improving the overall reliability of the equipment.

[0049] The conveying device has a simplified structure and a significantly reduced failure rate. In actual use, the failure rate can be reduced by more than 90%, and maintenance time is greatly shortened to 16% of the original time, ultimately achieving continuous and efficient operation of the production line. It also brings significant economic benefits, with an average annual increase of approximately 812.5 tons in the production of water-reducing agent polyether, generating economic benefits of 6.5 million yuan per year.

[0050] Reference Figure 2 The conveying roller includes a roller 22 and two roller shafts 23, and the drive sprocket 21 is coaxially fixed with the roller 22.

[0051] Roller 22 and roller shaft 23 are coaxially arranged. The diameter of roller 22 is larger than the diameter of roller shaft 23. A bearing is sleeved on roller shaft 23 and embedded in the inner cavity of roller 22, allowing roller 22 to rotate relative to roller shaft 23. The axis of rotation of roller 22 is the axis of roller 22. Two roller shafts 23 are located at both ends of roller 22 along the first direction and are respectively mounted on bracket 1.

[0052] In this application, the fact that the conveying roller is rotatably mounted on the bracket 1 around its own axis means that the conveying roller is mounted on the bracket 1 and all rollers 22 can rotate around their own axes so that the material placed above the rollers 22 can move in the first direction.

[0053] Whether the roller 23 can rotate around its own axis is not limited. In this embodiment, the roller 23 cannot rotate around its own axis. In another embodiment, the roller 23 can rotate around its own axis. Specifically, the roller 23 can be a cylindrical shaft, and bearings fixed on the bracket 1 are sleeved on the outer side of the roller 23.

[0054] For clarity, the sprocket is represented by a circular wheel in the attached diagram, and the chain 4 is represented by an annular belt.

[0055] Reference Figure 2 As an optional solution, the support 1 includes a base frame 11 and two connectors 12 fixed on the base frame 11, with the two connectors 12 located at both ends of the drive roller 2 in the width direction.

[0056] The upper end of the connector 12 is provided with a connecting groove 121, which passes through the opposite ends of two connectors 12. Multiple connecting grooves 121 are arranged sequentially along the first direction. The connecting grooves 121 are used to accommodate the end of the conveying roller.

[0057] Two roller shafts 23 are located at the two ends of the roller 22 respectively, and are rotatably connected to the roller 22.

[0058] For example, the base frame 11 is fixed on the ground, the connector 12 is a steel plate with a length along the first direction and a thickness along the second direction, the connector 12 is fixed on the base frame 11, the two connectors 12 are spaced apart along the second direction and are located at both ends of the drive roller 2 along the second direction.

[0059] The upper end of the connector 12 is provided with a connecting groove 121. Multiple connecting grooves 121 are provided, and each connecting groove 121 corresponds to a roller 23. The roller 23 is placed in the connecting groove 121.

[0060] Reference Figure 4 One end of the roller shaft 23 is rotatably connected to the roller 22, and the other end is used to place in the connecting groove 121. The cross-sectional area of ​​the end of the roller shaft 23 connected to the roller 22 is larger than the cross-sectional area of ​​the end connected to the connecting groove 121. The cross-section of the end of the roller shaft 23 used to place in the connecting groove 121 is elongated. The bottom cross-sectional shape of the connecting groove 121 is semi-circular, and the top cross-sectional shape is rectangular. The connecting groove 121 passes through both ends of the connector 12 along the second direction.

[0061] In another embodiment, the connector 12 can be a channel steel, and the connecting groove 121 can also pass through only one end of the two connectors 12 that are opposite each other in the second direction.

[0062] The roller 23 is placed in the connecting groove 121. The two side walls of the roller 23 along the first direction abut against the two side walls of the connecting groove 121 along the first direction. The roller 23 is subjected to its own gravity, so that the bottom abuts against the bottom of the connecting groove 121.

[0063] The connection groove 121 enables quick connection between the conveyor roller and the connector 12, and facilitates quick disassembly and installation when the chain 4 and sprocket on the conveyor roller fail.

[0064] Reference Figure 4 As an alternative, the roller 23 is embedded in the connecting groove 121, and the uppermost part of the roller 23 is flush with the upper end surface of the connector 12.

[0065] For example, the uppermost part of roller 23 refers to the uppermost part of roller 23 used for connecting to the connecting groove 121. The uppermost part of roller 23 is flush with the upper end face of connector 12. When roller 23 jumps in the vertical direction, roller 23 will protrude from the upper end face of connector 12, which facilitates inspection or detection of whether roller 23 has jumped in the vertical direction.

[0066] Reference Figure 3 as well as Figure 4 As an optional solution, the conveying device further includes a pressure plate 5, which is located above the connector 12 and is detachably fixed to the connector 12 to press the roller 23 into the connecting groove 121.

[0067] For example, the pressure plate 5 is a long strip plate disposed above the connector 12. The pressure plate 5 is detachably fixed to the connector 12 and presses against the upper end face of the roller 23.

[0068] Compared with the prior art where the roller shaft is placed directly in the groove on the support, this application adds a pressure plate 5. The pressure plate 5 can press the roller shaft 23 tightly onto the connector 12, which can effectively press the driving roller 2 and the driven roller 3, reducing the "gear skipping" phenomenon during operation, that is, the driving sprocket 21 or the driven sprocket 31 disengaging from the chain 4 due to the up and down vibration of the conveyor roller, thus ensuring the smoothness of the chain 4 transmission.

[0069] Reference Figure 4 As an optional solution, the conveying device further includes a clamping bolt 6, which is threadedly connected to the connector 12, and the clamping bolt 6 presses and fixes the pressure plate 5 onto the connector 12.

[0070] For example, the clamping bolts 6 are arranged in a vertical direction, the screw of the clamping bolts 6 passes through the pressure plate 5 and is threadedly connected to the connector 12, and the nut of the clamping bolts 6 presses the pressure plate 5 onto the connector 12. Multiple clamping bolts 6 are arranged at intervals along the first direction.

[0071] The pressure plate 5 and the connector 12 are detachably connected by the clamping bolt 6. When the conveyor roller or chain 4 fails, it is easy to remove the pressure plate 5 from the connector 12 and install it, which shortens the maintenance time and reduces the losses caused by downtime.

[0072] Reference Figure 3 as well as Figure 4 As an optional solution, the pressure plate 5 includes a first plate 51 and a second plate 52 arranged sequentially along a first direction; a semi-circular hole 53 is respectively opened at one end of the first plate 51 and the second plate 52, and the two semi-circular holes 53 on the first plate 51 and the second plate 52 form a first hole.

[0073] The screw of the clamping bolt 6 passes through the first hole and is threadedly connected to the connector 12.

[0074] Reference Figure 4For example, the pressure plate 5 includes multiple segments. Two adjacent segments along the first direction are a first plate 51 and a second plate 52. Each of the first plate 51 and the second plate 52 has a semi-circular hole at one opposite end along the first direction. The two semi-circles have the same diameter, and the diameter of the two semi-circular holes is smaller than the width of the pressure plate 5 along the second direction. When the two end faces of the first plate 51 along the second direction are flush with the two end faces of the second plate 52 along the second direction, the two semi-circular holes are coaxial, and at this time, the two semi-circular holes form the first hole.

[0075] The screw of the clamping bolt 6 passes through the first hole and is threaded to the connector 12, and the nut presses against the first plate 51 and the second plate 52 respectively.

[0076] While the clamping bolt 6 presses the first plate 51 and the second plate 52 vertically onto the connector 12, the screw in the first hole blocks the movement of the pressure plate 5 in the second direction, thus achieving a stable connection between the first plate 51 and the second plate 52 and the connector 12.

[0077] By fixing multiple sections of the pressure plate 5 to the connector 12, the length of the pressure plate 5 can be reduced, which helps to reduce the cost of the pressure plate 5 and facilitates the installation and disassembly of the pressure plate 5.

[0078] When the conveyor roller malfunctions, the corresponding pressure plate 5 can be disassembled separately, without having to remove the entire pressure plate 5 from the connector 12, thus improving maintenance efficiency.

[0079] When the pressure plate 5 is too long, the middle of the pressure plate 5 is prone to warping and separating from the connecting piece 12, which affects the pressing effect of the pressure plate 5 on the roller shaft 23. The setting of multiple first plates 51 and second plates 52 can improve the fit between the pressure plate 5 and the roller shaft 23 and reduce the occurrence of "gear skipping" phenomenon during operation.

[0080] Furthermore, a washer is fitted on the clamping bolt 6, and the washer is positioned between the nut and the connector 12.

[0081] Reference Figure 2 As an optional solution, the conveying device further includes a drive assembly 9, which includes a reducer 91, a first drive sprocket 92, a second drive sprocket 93, and a drive chain 94.

[0082] The first drive sprocket 92 is coaxially and fixedly connected to the output end of the reducer 91; the second drive sprocket 93 is coaxially and fixedly connected to the drive sprocket 21; the drive chain 94 meshes with the first drive sprocket 92 and the second drive sprocket 93.

[0083] For example, the second drive sprocket 93 is coaxially fixed with the roller 22 of the drive roller 2. Specifically, the second drive sprocket 93 and the drive sprocket 21 are coaxially fixed on a round tube, which is sleeved on the outside of the roller 22 and welded to the roller 22.

[0084] The drive chain 94 is sleeved on the outside of the first drive sprocket 92 and the second drive sprocket 93 and meshes with the first drive sprocket 92 and the second drive sprocket 93 to realize chain transmission between the reducer 91 and the drive roller 2.

[0085] The drive roller 2 is rotated by the reducer 91, which helps to increase the torque output of the drive assembly 9. The chain drive between the reducer 91 and the drive roller 2 is achieved by the first drive sprocket 92, the second drive sprocket 93 and the drive chain 94, which has a simple structure and high transmission efficiency.

[0086] Reference Figure 2 As an optional solution, the drive assembly 9 also includes a motor 95, the output shaft of which is connected to the input end of the reducer 91.

[0087] Specifically, the output shaft of motor 95 and the input end of reducer 91 are coaxially fixed using a coupling. When motor 95 starts, it drives the input end of reducer 91 to rotate. The output speed of reducer 91 is relatively lower than that of motor 95, but the torque is relatively higher. Motor 95 provides power to reducer 91, which increases the torque output of drive assembly 9, enabling reducer 91 to drive the second drive sprocket 93 to rotate via drive chain 94.

[0088] Reference Figure 2 As an optional solution, the bracket 1 also includes two angle steels 13, which are respectively located on opposite sides of the two connectors 12. The two angle steels 13 are fixedly connected to the two connectors 12 in a one-to-one correspondence, and both angle steels 13 are fixedly connected to the base frame 11.

[0089] For example, the angle steel 13 is used to fix the connector 12 to the base frame 11. The two angle steels 13 are spaced apart along the second direction. The two angle steels 13 are respectively located on opposite sides of the two connectors 12. The length of the angle steel 13 is set along the first direction.

[0090] Angle steel 13 is detachably fixed to base frame 11 using bolts, and angle steel 13 is welded to connector 12. In another embodiment, angle steel 13 and connector 12 are fixedly connected using bolts.

[0091] The angle steel 13 facilitates the connection and fixation of the connecting piece 12 to the base frame 11. The angle steel 13 and the connecting piece 12 are connected by bolts, which facilitates the installation and disassembly of the conveyor roller in the conveying device and the maintenance of the conveying device. The angle steel 13 is located on the opposite side of the two connecting pieces 12, which can prevent the connecting pieces 12 from moving away from each other in the second direction, thereby improving the stability of the conveyor roller connected to the connecting piece 12.

[0092] Reference Figure 5 as well as Figure 6 As an alternative, the connecting groove 121 includes an adjusting groove 1211, which is used to accommodate the roller shaft 23 of the end roller 32, which is the driven roller 3 on the same chain 4 that is furthest from the driving roller 2 in the first direction.

[0093] The conveying device also includes a fixing plate 7 and an adjusting bolt 8. The fixing plate 7 is fixed to the connecting member 12 and is located on the side of the adjusting groove 1211 facing the drive roller 2 in the first direction. The adjusting bolt 8 is threadedly connected to the fixing plate 7 and presses against the roller shaft 23 of the end roller 32 in the first direction.

[0094] Reference Figure 6 For example, the cross-section of the adjustment groove 1211 is rectangular, and the cross-section represents a plane perpendicular to the second direction. The adjustment groove 1211 extends through both ends of the connector 12 along the second direction. The gap between the two side walls of the adjustment groove 1211 along the first direction is greater than the distance between the two end faces of the roller shaft 23 of the end roller 32 along the first direction.

[0095] The fixing plate 7 is fixed to the two connecting members 12. In this embodiment, the fixing plate 7 is fixed to the two connecting members 12 on opposite sides along the second direction. In another embodiment, the fixing plate 7 is fixed to the two connecting members 12 on opposite sides along the second direction. The fixing plate 7 is provided with a threaded hole along the first direction. The screw of the adjusting bolt 8 passes through the threaded hole on the fixing plate 7 and then abuts against the roller shaft 23 of the end roller 32 along the first direction.

[0096] The roller shaft 23 of the end roller 32 can move along the first direction within the adjusting groove 1211. By rotating the adjusting bolt 8, the pressing position between the adjusting bolt 8 and the roller shaft 23 of the end roller 32 is adjusted, thereby adjusting the position of the end roller 32 along the first direction.

[0097] The end roller 32 moves away from the drive roller 2 along the first direction, which can tension the chain 4 and reduce or prevent the chain 4 from disengaging from the driven sprocket 31. The end roller 32 moves closer to the drive roller 2 along the first direction, which can relax the chain 4, making it easier to separate the chain 4 from the driven sprocket 31 during maintenance, and also making it easier to install the chain 4 on the driven sprocket 31 of the end roller 32, thus improving maintenance efficiency.

[0098] Reference Figure 7 Furthermore, there are two fixing plates 7 and two adjusting bolts 8. The two fixing plates 7 are set on both sides of the adjusting groove 1211 along the first direction. The two adjusting bolts 8 are threadedly connected to the two fixing plates 7 respectively. The two adjusting bolts 8 are set opposite to each other. After the screws of the two adjusting bolts 8 pass through the fixing plates 7, they abut against the two end faces of the roller shaft 23 of the end roller 32 along the first direction.

[0099] The two adjusting bolts 8 press against the two ends of the roller shaft 23 of the end roller 32 along the first direction, which can improve the stability of the connection between the adjusting bolts 8 and the roller shaft 23, reduce the vibration of the end roller 32 during use, and reduce the occurrence of the chain 4 and the end roller 32 separating.
