Description

Technical Field

[0001] This invention belongs to the field of conveyor belt technology, specifically relating to a conveyor belt device and its usage method that is easy to maintain. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Enterprises involve conveyor lines in the processing and packaging of products. Conveyor lines use conveyor belts as a power source. In actual production, in order to improve production efficiency, conveyor lines are often designed with different heights or a certain angle of inclination. Therefore, conveyor belts not only need to adapt to different types of conveyor lines, but also need to reduce the downtime of the conveyor line during conveyor maintenance and reduce production capacity loss. However, when repairing or replacing PU drive belts or bearings of existing conveyor belts, it is necessary to remove the bearings, sprockets, chains and other accessories on the frame before the drive shaft roller can be removed. The disassembly and assembly structure is complex and time-consuming.

[0004] CN113844837B discloses a folding conveyor belt device, including a first conveyor section, a second conveyor section, a third conveyor section, and a first telescopic mechanism; the third conveyor section is hinged to the end of the second conveyor section opposite to the first conveyor section; the telescopic end of the first telescopic mechanism is connected to the third conveyor section, and the fixed end is connected to the second conveyor section, so as to drive the third conveyor section to rotate around the hinge axis. It solves the problem that the conveyor belt cannot adapt to the conveyor lines of different heights, but cannot adapt to the situation where there is a certain tilt angle between the conveyor lines. At the same time, its shaft roller and belt installation structure is similar to the traditional conveyor belt structure, and the disassembly process is complicated. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a conveyor belt device and method for easy maintenance. By using a fixed support and a floating support, the same section of conveyor belt is supported by two support sections. The rotating plates on both sides of the floating support can rotate independently around the fixed support. This not only allows for the transition between conveyor lines of different heights and angles, but also enables the quick release of the drive shaft rollers through rapid belt release, reducing production line downtime and minimizing production capacity losses caused by mechanical failures.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] In a first aspect, the present invention provides a conveyor belt device that is easy to maintain, including a frame, a fixed support, a floating support, a drive shaft roller, a driven shaft roller, a segmented coupling, and a power input shaft;

[0008] The fixed bracket has a mounting base at its bottom, which is used to fix it to the conveyor belt frame. One end of the fixed bracket has a U-shaped fixing seat, and the other end has an arc-shaped waist hole and a first positioning hole. One end of the floating bracket has a fastening shaft hole and a second positioning hole. A positioning pin is installed in the first positioning hole and the second positioning hole. A fastener is installed in the fastening shaft hole. The fastener can slide in the arc-shaped waist hole, allowing the floating bracket to rotate independently around the positioning pin. The other end of the floating bracket has an adjustment groove for the conveyor belt.

[0009] The drive shaft roller is engaged with the U-shaped fixed seat, and the driven shaft roller is installed in the adjusting groove; the drive shaft roller is provided with transmission shafts at both ends, and the transmission shafts are connected to the power input shaft through a segmented coupling; the segmented coupling consists of a first coupling terminal, a cross slider, and a second coupling terminal, the first coupling terminal is inserted into the transmission shaft and can move axially along the transmission shaft, the second coupling terminal is inserted into the power input shaft and can move axially along the power input shaft, and the cross slider is installed between the first coupling terminal and the second coupling terminal.

[0010] Furthermore, the fixing bracket consists of two parallel and identical fixing plates. The U-shaped fixing seat, the arc-shaped waist hole and the first positioning hole are all set on the fixing plates, and the arc-shaped waist hole is set above the first positioning hole.

[0011] Furthermore, the floating support consists of two parallel and identical rotating plates, the adjusting groove is arranged on the rotating plates, the driven shaft roller has shaft heads at both ends, the shaft heads are installed in the adjusting groove, and a fisheye bearing is provided between the shaft head and the adjusting groove.

[0012] Furthermore, a rolling bearing and a bearing sleeve are provided between the drive shaft and the mounting base, the rolling bearing and the bearing sleeve being an interference fit, and the bearing sleeve having a V-shaped cross-section.

[0013] Furthermore, a flat key is provided between the drive shaft and the first coupling terminal for transmitting torque between the drive shaft and the first coupling terminal; a positioning hole is provided on the side of the first coupling terminal, and a positioning screw is provided in the positioning hole for axial positioning between the first coupling terminal and the drive shaft.

[0014] Furthermore, the end of the first coupling terminal is provided with a sliding groove, which cooperates with the slider on one side of the cross slider.

[0015] Furthermore, the second coupling terminal has the same structure as the first coupling terminal.

[0016] Furthermore, the power input shaft is fixedly mounted on the frame via a rotating assembly; a sprocket is fixedly connected to the end of the power input shaft away from the second coupling terminal, and the sprocket can be connected to the drive motor via a chain.

[0017] Furthermore, an adjustment assembly is provided at the end of the adjustment groove. The adjustment assembly consists of an adjustment screw and an adjustment screw seat. The adjustment screw seat is rotatably disposed on one side of the rotating plate. The adjustment screw seat is provided with a threaded hole that mates with the adjustment screw. One end of the adjustment screw is provided with an adjustment hinge seat, and the other end is provided with an adjustment column. The adjustment hinge seat is hinged to the end of the driven shaft roller.

[0018] Secondly, the present invention also provides a method for using a conveyor belt device that is easy to maintain, comprising the following steps:

[0019] S1. When the height of the conveyor lines is different: When the height of the conveyor lines at both ends of the conveyor belt is inconsistent, loosen the fastener at one end of the floating bracket, manually adjust the other end of the floating bracket, and tighten the fastener when it is adjusted to the required height. At this time, the conveyor belt is in a slack state. Rotate the adjusting column until the belt is in a taut state.

[0020] S2. When maintaining the conveyor belt: Loosen the positioning screw on the first coupling terminal, push the first coupling terminal to move axially along the drive shaft, so that the first coupling terminal is disengaged from the cross slider. Then loosen the fastener at one end of the floating bracket and manually lift the other end of the floating bracket. At this time, the conveyor belt is in a slack state and the drive shaft is disconnected from the power input shaft. Remove the drive shaft roller from the U-shaped fixed seat and remove the driven shaft roller from the adjustment groove at the same time. If a different size belt is replaced, simply adjust the adjustment screw to tension the belt.

[0021] Compared with the prior art, the advantages and positive effects of this invention are:

[0022] This invention breaks away from the traditional conveyor belt structure. Instead of a single conveyor belt section being supported by two brackets—a fixed bracket and a floating bracket—the invention utilizes arc-shaped waist holes and positioning hinge holes to allow the floating bracket to rotate around the fixed bracket. By incorporating fisheye bearings at both ends of the driven shaft roller, it not only facilitates transitions between conveyor lines of different heights and angles but also enables rapid belt release and quick disassembly of the drive shaft roller. The drive shaft roller engages with the fixed bracket, and can be removed simply by folding the bracket at a small angle, facilitating belt replacement. When replacing the drive shaft roller or related belt components, there is no need to disassemble the power input shaft and rotating components. Simply loosen the screws on the first or second coupling terminal, remove the cross slider, and the drive shaft roller can be removed, significantly reducing production line downtime and minimizing production losses due to mechanical failures.

[0023] The floating support of this invention can not only rotate around the positioning pin and adjust and fix the angle through fasteners, but also adjust the wheel distance between the drive shaft roller and the driven shaft roller by cooperating with the pitch adjustment component. This allows the conveyor belt to adapt to conveyor lines of different heights and to tension belts of different sizes, thus improving the versatility of the conveyor belt device.

[0029] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] This embodiment discloses a conveyor belt device that is easy to maintain, such as... Figures 1-2 As shown, the system includes a frame, a fixed support 1, a floating support 2, a drive shaft roller 3, a driven shaft roller 4, a segmented coupling 8, and a power input shaft 5. The fixed support 1 has a mounting base 14 at its bottom, which fixes it to the conveyor belt frame. One end of the fixed support 1 has a U-shaped fixing seat 7, and the other end has an arc-shaped waist hole 11 and a first positioning hole. One end of the floating support 2 has a fastening shaft hole and a second positioning hole. Positioning pins 9 are installed in the first and second positioning holes, and fastening pins are installed in the fastening shaft hole. Component 10, the fastener 10 is movable in the arc-shaped waist hole 11, allowing the floating bracket 2 to rotate around the positioning pin 9; the other end of the floating bracket 2 is provided with a conveyor belt adjustment groove 6; the drive shaft roller 3 is engaged with the U-shaped fixed seat 7, the driven shaft roller 4 has shaft heads at both ends, the shaft heads are installed in the adjustment groove 6, a fisheye bearing 16 is provided between the shaft head and the adjustment groove 6, the drive shaft roller 3 has transmission shafts at both ends, the transmission shafts are connected to the power input shaft 5 through a segmented coupling 8; such as Figure 3 As shown, the segmented coupling 8 consists of a first coupling terminal 8-1, a cross slider 8-3, and a second coupling terminal 8-2. The first coupling terminal 8-1 is inserted into the drive shaft and can move axially along the drive shaft. The second coupling terminal 8-2 is inserted into the power input shaft 5 and can move axially along the power input shaft 5. The cross slider 8-3 is installed between the first coupling terminal 8-1 and the second coupling terminal 8-2.

[0032] The fixed bracket 1 consists of two parallel fixed plates. The mounting base 14 is located at one end of the fixed plate, and the arc-shaped waist hole 11 and the first positioning hole are located at the other end of the fixed plate. The arc-shaped waist hole 11 is located above the first positioning hole. The two fixed plates have the same structure. The mounting base 14 is used to install the drive shaft roller 3. The drive shaft roller 3 is mainly used to drive the belt 13 to rotate. The transmission shaft at its end is used for support and power source. A rolling bearing and a bearing sleeve 15 are provided between the transmission shaft and the mounting base 14. The rolling bearing and the bearing sleeve 15 are interference fit. The cross section of the bearing sleeve 15 is V-shaped, which can effectively prevent the axial movement of the drive shaft roller 3. The segmented coupling 8 consists of a first coupling terminal 8-1, a cross slider 8-3, and a second coupling terminal 8-2. The first coupling terminal 8-1 is inserted into the transmission shaft and can move along the axial direction of the transmission shaft. A flat key is provided between the first coupling terminal 8-1 and the drive shaft for torque transmission between the drive shaft and the first coupling terminal 8-1. A positioning hole is provided on the side of the first coupling terminal 8-1, and a positioning screw 8-4 is provided in the positioning hole. The positioning screw 8-4 is only used for positioning between the first coupling terminal 8-1 and the drive shaft and does not need to transmit torque. A sliding groove 8-5 is provided at the end of the first coupling terminal 8-1. The sliding groove 8-5 cooperates with the slider 8-6 on one side of the cross slider 8-3 for transmitting torque between the first coupling terminal 8-1 and the second coupling terminal 8-2. The second coupling terminal 8-2 has the same structure as the first coupling terminal 8-1. The second coupling terminal 8-2 is inserted into the power input shaft 5 and can move along the axial direction of the power input shaft 5. The cross slider 8-3 is installed between the first coupling terminal 8-1 and the second coupling terminal 8-2.

[0033] A sprocket is fixedly connected to the end of the power input shaft 5 away from the second coupling terminal 8-2. The sprocket can be connected to the drive motor via a chain. The power input shaft 5 is fixedly mounted on the frame via a rotating assembly. When it is necessary to replace the drive shaft roller 3 or belt 13 and related components, it is not necessary to disassemble the power input shaft 5 and the rotating assembly. Simply loosen the positioning screw 8-4 on the first coupling terminal 8-1 or the screw on the second coupling terminal 8-2, and gently push the first coupling terminal 8-1 or the second coupling terminal 8-2 to disengage it from the cross slider 8-3. After removing the cross slider 8-3, the drive shaft roller 3 can be removed. This significantly reduces the downtime of the production line and reduces the production capacity loss caused by mechanical failure.

[0034] Each floating support 2 consists of two parallel rotating plates. A fastening shaft hole and a second positioning hole are located at one end of each rotating plate. A fastener 10, a semi-threaded bolt, is installed in the fastening shaft hole and can move within the arc-shaped waist hole 11, allowing the floating support 2 to rotate around the positioning pin 9. The positioning pin 9 hinges the first and second positioning holes, allowing the floating support 2 to rotate relative to the fixed support 1. The fastener 10 enables angle adjustment and fixation between the floating support 2 and the fixed support 1. The other end of the floating support 2 is provided with a conveyor belt adjustment groove 6, which cooperates with the fisheye bearing 16, enabling the driven roller to rotate around the adjustment groove 6 in multiple directions. The rotation of the drive shaft roller 3 and the driven shaft roller 4 is achieved by adjusting the distance between the drive shaft roller 3 and the driven shaft roller 4. The drive shaft roller 3 is connected to the end of the fixed bracket 1, which consists of an adjusting screw and an adjusting screw seat. The adjusting screw seat is rotatably mounted on one side of the rotating plate and has an internal threaded hole for engaging with the adjusting screw. One end of the adjusting screw is provided with an adjusting hinge seat, which is hinged to the end of the driven shaft roller 4. The other end is provided with an adjusting column. By turning the adjusting column, the wheelbase between the drive shaft roller 3 and the driven shaft roller 4 can be adjusted, so that the conveyor belt can adapt to conveyor lines of different heights and can tension belts 13 of different sizes. Since the drive shaft roller 3 is engaged with the fixed bracket 1, the drive shaft roller 3 can be removed and the belt 13 replaced simply by folding the bracket at a small angle.

[0035] How to use:

[0036] S1. When the height of the conveyor lines is different: When the height of the conveyor lines at both ends of the conveyor belt is inconsistent, loosen the fastener 10 at one end of the floating bracket 2, manually adjust the other end of the floating bracket 2, and tighten the fastener 10 when it is adjusted to the required height. At this time, the belt 13 of the conveyor belt is in a slack state. Use a tool to rotate the adjusting column on the adjusting screw. Under the push of the adjusting screw, the hinge seat drives the driven shaft roller 4 to move until the belt 13 is in a taut state.

[0037] S2. When maintaining the conveyor belt: Loosen the positioning screw 8-4 on the first coupling terminal 8-1, push the first coupling terminal 8-1 to move axially along the drive shaft, so that the first coupling terminal 8-1 is disengaged from the cross slider 8-3. Then loosen the fastener 10 at one end of the floating bracket 2, manually lift the other end of the floating bracket 2. At this time, the conveyor belt 13 is in a slack state, and the drive shaft is disconnected from the power input shaft 5. Remove the drive shaft roller 3 from the U-shaped fixed seat 7, and at the same time remove the driven shaft roller 4 from the adjustment groove 6. Then the belt 13 can be replaced and the shaft roller can be maintained. If a belt 13 of a different size is replaced, the belt 13 can be tensioned by simply adjusting the adjustment screw.

[0038] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
