Description

Technical Field

[0001] The utility model relates to the technical field of transmission belts, in particular to a driving device of a belt conveyor and a belt conveyor. Background Art

[0002] In the field of logistics sorting, the driving devices of belt conveyors on the market currently mostly use motors to drive the driving rollers at the head through chains, and the driving rollers then drive the belts, so that the belts convey goods. However, there are many problems with this structure. First, such a structure has high requirements for the rotation speed. Since the driving rollers are driven by chains, the transmission process is noisy and requires high maintenance. Transmission parts such as chains and gears need to be lubricated regularly to maintain a good operating state, otherwise they may wear out faster. At the same time, due to the chain gap and other mechanical losses, the transmission efficiency of chain transmission may not be as good as other types of transmission systems, and the installation and adjustment of chains and gears are relatively complicated, requiring professional technology and tools. Secondly, the chain needs to be oiled and maintained for long-term use. On the other hand, the use of chain drive also requires the installation of additional tensioning rollers and adjustment devices for adjusting the belts. The various devices are scattered and cannot be integrated. This has a great impact on the production efficiency of the assembly line, and it is inconvenient to maintain it later. It is necessary to provide additional protection for parts such as motors and drive sprockets.

[0003] Therefore, it is necessary to study a belt conveyor drive device with high integration, low noise and easy maintenance. Utility Model Content

[0004] The utility model provides a driving device of a belt conveyor and a belt conveyor, aiming to solve one or more of the above problems and other potential problems.

[0005] The utility model provides a driving device for a belt conveyor in the first aspect, comprising a motor, characterized in that it also comprises: a main body, the motor is mounted on the main body, the main body is provided with a driving mechanism for driving the belt transmission and adjusting the belt tension, and a synchronous mechanism for driving the driving mechanism to rotate with the motor, wherein the synchronous mechanism comprises a driving wheel connected to the output end of the motor, a driven wheel connected to the driving mechanism, and a synchronous belt connected to the driving wheel and the driven wheel through an arc surface transmission and driving the driven wheel to rotate with the driving wheel; the driving mechanism comprises a driving roller connected to the driven wheel and rotating with the driven wheel, a tensioning roller for cooperating with the driving roller to drive the belt transmission and adjust the belt tension, and an adjustment part for adjusting the installation position of the tensioning roller on the main body.

[0006] The driving device provided by the utility model adopts a lower-layer installation and can be installed at any position below the belt conveyor, and has a wide range of applications. In this embodiment, a motor is used to drive the driving mechanism through a synchronous belt, which ensures high-intensity rotation while avoiding chain noise. Furthermore, the driving mechanism adjusts the tension of the belt while driving the belt transmission, ensuring that the belt can be adjusted to a suitable tension.

[0007] The utility model utilizes a tensioning roller to transfer the belt on the belt conveyor to a driving roller, which drives the belt to be driven, and by changing the installation position of the adjustment part on the main body, the tension is adjusted according to the transmission condition of the belt, ensuring that the belt is adjusted to a suitable tension and improving the stability of the belt transmission.

[0008] In some embodiments, an observation mechanism for observing the working status of the synchronization mechanism and the driving mechanism is also included.

[0009] The utility model integrates the motor, the driving mechanism, the synchronization mechanism, the observation mechanism, etc., thereby improving the assembly efficiency and the convenience of subsequent maintenance.

[0010] In some embodiments, the adjustment part includes a sliding member arranged at both ends of the tensioning roller and connected to the main body, a guide member installed on the main body for the sliding member to move, the guide member is provided with an elastic member for providing a buffering force to the sliding member, and a positioning member for fixing the position of the sliding member on the guide member, and the tensioning roller is rotatably arranged relative to the sliding member.

[0011] In some embodiments, the positioning member, the elastic member, and the sliding member are sleeved on the guiding member one by one, and two ends of the elastic member are respectively connected to the sliding member and the positioning member.

[0012] In the embodiment, the positioning member, the elastic member, and the sliding member are sleeved on the guide member one by one, and the sliding member moves on the guide member to adjust the installation position of the tensioning roller on the main body, thereby adjusting the distance between the tensioning roller and the driving roller, and the tension of the belt is controlled by the distance between the tensioning roller and the driving roller to make it at an appropriate tension level. After determining the position of the sliding member on the guide member, the moving range of the sliding member is locked by tightening the positioning member.

[0013] Furthermore, since an elastic member is provided between the sliding member and the positioning member, the sliding member can slide left and right on the guiding member as the elastic member expands and contracts. When the belt is transmitted between the tensioning roller and the driving roller, the belt will exert forces in opposite directions on the tensioning roller and the driving roller. At this time, the elastic member will stretch or compress under the action of the force, providing a buffer force and a buffer space for the sliding member. As the elastic member stretches or compresses, the sliding member moves within the elastic range of the elastic member and drives the tensioning roller to move relative to the driving roller, so as to balance the forces on the tensioning roller and the driving roller, reduce the loss of the driving roller and the tensioning roller caused by the force during the belt transmission, and extend the life of the driving mechanism. The tensioning roller is arranged to rotate relative to the sliding member to prevent the movement of the sliding member during the belt transmission from affecting the rotation of the tensioning roller and affecting the use effect.

[0014] In some embodiments, the main body includes a drive compartment for installing the drive mechanism and a power compartment for installing the motor, the drive compartment is fixedly connected to the power compartment, a sliding groove is provided on the side of the drive compartment, and the sliding member passes through the sliding groove and is connected to the guide member.

[0015] In the embodiment, the drive mechanism and the motor are placed in different compartments of the main body, and the drive mechanism or the motor can be inspected by disassembling the drive compartment or the power compartment separately. When in use, the power compartment is fixedly connected to the drive compartment to prevent the movement of the two from affecting the normal transmission of the belt. Furthermore, by setting a sliding groove on the drive compartment to limit the sliding track of the tensioning roller, the tensioning roller is prevented from being separated from the main body due to the force of the belt, which affects the transmission effect.

[0016] In some embodiments, a rotating shaft is provided at the center of the driving roller, a driven connecting portion is provided on the side of the driving bin, the driven wheel is mounted on the driven connecting portion, and the rotating shaft is connected to the driven wheel through the driven connecting portion.

[0017] In the embodiment, the driven wheel is connected to the rotating shaft of the driving roller. The driven wheel rotates with the driving wheel, driving the rotating shaft to rotate, thereby driving the driving roller to rotate. The belt is wound between the tensioning roller and the driving roller. After being adjusted to a suitable tension level, the friction between the belt and the driving roller is utilized to make the belt transmit power as the driving roller rotates.

[0018] In some embodiments, an active connection portion is provided on the side of the power compartment, the driving wheel is mounted on the active connection portion, and the output end of the motor is connected to the driving wheel through the active connection portion.

[0019] In the embodiment, the motor is fixed in the power compartment and the output end of the motor is connected to the active connection part of the power compartment. After the motor is started, the output end of the motor drives the active wheel on the active connection part to rotate, and the active wheel drives the driven wheel to rotate through the synchronous belt, thereby starting the drive mechanism.

[0020] In some embodiments, the viewing mechanism includes a first transparent viewing piece installed on the main body and covering the synchronization mechanism, and a second transparent viewing piece for covering the adjustment part.

[0021] In the embodiment, the synchronization mechanism and the adjustment part are respectively covered with a first transparent observation piece and a second transparent observation piece, so that the staff can observe the working status of the synchronization mechanism and the adjustment part respectively and remove them for adjustment at any time.

[0023] In some embodiments, the belt conveyor further includes a deviation correction mechanism for guiding the belt transmission trajectory.

[0024] In the embodiment, the belt conveyor is further provided with a deviation correction mechanism, and the belt contacts the deviation correction mechanism for transmission and limits the transmission trajectory of the belt, thereby preventing the belt from moving left and right on the driving roller or the tensioning roller and detaching from the driving mechanism.

[0025] By implementing the above technical solution, the utility model has the following advantages:

[0026] 1. The driving device provided by the utility model adopts a lower-layer installation and can be installed at any position below the belt conveyor.

[0038] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0039] The present embodiment provides a driving device for a belt conveyor, comprising a motor a, characterized in that it also comprises: a main body 1, wherein the motor a is mounted on the main body 1, and the main body 1 is provided with a driving mechanism 2 for driving a belt b1 for transmission and adjusting the tension of the belt b1, and a synchronous mechanism 3 for driving the driving mechanism 2 to rotate with the motor a, wherein the synchronous mechanism 3 comprises a driving wheel 31 connected to the output end a1 of the motor a, a driven wheel 32 connected to the driving mechanism 2, and a synchronous belt 33 connected to the arc surface of the driving wheel 31 and the driven wheel 32 for driving the driven wheel 32 to rotate with the driving wheel 31; the driving mechanism 2 comprises a driving roller 21 connected to the driven wheel 32 and rotating with the driven wheel 32, a tensioning roller 22 for cooperating with the driving roller 21 to drive the belt transmission and adjust the tension of the belt b1, and an adjusting portion 23 for adjusting the installation position of the tensioning roller 22 on the main body 1.

[0040] like Figures 1 to 4 As shown, in some embodiments, the driving device is installed in a lower layer and can be installed at any position below the belt conveyor. The belt b1 is connected to the driving mechanism 2, and the driving mechanism 2 is connected to the driven wheel 32 and transmits the belt b1 as the driven wheel 32 rotates. The driven wheel 32 and the driving wheel 31 are connected by a synchronous belt 33 to synchronize the rotation states of the two. The driving device uses a motor a to drive the driving mechanism 2 through a synchronous belt 33, which ensures high-intensity rotation while avoiding chain noise.

[0041] In some embodiments, the driving mechanism 2 utilizes a tensioning roller 22 to transfer the belt b1 on the belt conveyor to the driving roller 21, and the driving roller 21 drives the belt b1 to transmit. By changing the installation position of the adjustment part 23 on the main body 1, the belt b1 is driven to transmit and the tension is adjusted according to the transmission condition of the belt b1, ensuring that the belt b1 is adjusted to the appropriate tension, thereby improving the stability of the belt b1 transmission.

[0042] In some embodiments, an observation mechanism 4 is further included for observing the working status of the synchronization mechanism 3 and the drive mechanism 2. This embodiment integrates the motor a, the drive mechanism 2, the synchronization mechanism 3, the observation mechanism 4, etc., to improve the assembly efficiency and the convenience of subsequent maintenance.

[0043] In some embodiments, Figure 2 As shown, the adjustment part 23 includes a sliding member 231 arranged at both ends of the tensioning roller 22 and connected to the main body 1, a guide member 232 installed on the main body 1 for the sliding member 231 to move, an elastic member 233 is provided on the guide member 232 to provide a buffering force to the sliding member 231, and a positioning member 234 is used to fix the position of the sliding member 231 on the guide member 232, and the tensioning roller 22 is rotatably arranged relative to the sliding member 231.

[0044] In some embodiments, the positioning member 234 , the elastic member 233 , and the sliding member 231 are sleeved on the guide member 232 one by one, and two ends of the elastic member 233 are connected to the sliding member 231 and the positioning member 234 respectively.

[0045] In the embodiment, the positioning member 234, the elastic member 233, and the sliding member 231 are sleeved on the guide member 232 one by one, and the installation position of the tensioning roller 22 on the main body 1 is adjusted by moving the sliding member 231 on the guide member 232, thereby adjusting the distance between the tensioning roller 22 and the driving roller 21, and controlling the tension of the belt b1 by the distance between the tensioning roller 22 and the driving roller 21, so that it is at an appropriate tension. After determining the position of the sliding member 231 on the guide member 232, the moving range of the sliding member 231 is locked by tightening the positioning member 234.

[0046] In some embodiments, the guide member 232 is spirally connected to the positioning member 234 , and the positioning member 234 cannot move left or right on the guide member 232 after being locked.

[0047] Furthermore, since an elastic member 233 is provided between the sliding member 231 and the positioning member 234, the sliding member 231 can slide left and right on the guide member 232 as the elastic member 233 expands and contracts. The elastic member 233 can be selected from a spring, a silicone, or a resin. When the belt b1 is transmitted between the tensioning roller 22 and the driving roller 21, the belt b1 will exert forces in opposite directions on the tensioning roller 22 and the driving roller 21. At this time, the elastic member 233 will be stretched or compressed under the action of the force, providing a buffer force and a buffer space for the sliding member 231. As the elastic member 233 is stretched or compressed, the sliding member 231 moves within the elastic range of the elastic member 233 and drives the tensioning roller 22 to move relative to the driving roller 21, so as to balance the forces on the tensioning roller 22 and the driving roller 21, reduce the loss of the forces on the driving roller 21 and the tensioning roller 22 when the belt b1 is transmitted, and extend the life of the driving mechanism 2. The tensioning roller 22 is rotatably arranged relative to the sliding member 231 to prevent the movement of the sliding member 231 from affecting the rotation of the tensioning roller 22 and affecting the use effect during the transmission process of the belt b1.

[0048] In some embodiments, the main body 1 includes a drive compartment 12 for installing the drive mechanism 2 and a power compartment 11 for installing the motor a. The drive compartment 12 is fixedly connected to the power compartment 11. A sliding groove 121 is provided on the side of the drive compartment 12. The sliding member 231 passes through the sliding groove 121 and is connected to the guide member 232.

[0049] In some embodiments, the main body 1 is fixed to the bottom of the belt conveyor by bolts, and the drive compartment 12 and the power compartment 11 are fixedly connected by bolts to facilitate disassembly and installation.

[0050] In the embodiment, the drive mechanism 2 and the motor a are placed in different compartments of the main body 1, and the drive mechanism 2 or the motor a can be inspected by separately disassembling the drive compartment 12 or the power compartment 11. When in use, the power compartment 11 is fixedly connected to the drive compartment 12 to prevent the movement of the two from affecting the normal transmission of the belt b1. Furthermore, by setting a sliding groove 121 on the drive compartment 12 to limit the sliding track of the tensioning roller 22, the tensioning roller 22 is prevented from being separated from the main body 1 due to the force of the belt b1, thereby affecting the transmission effect.

[0051] In some embodiments, a rotating shaft 211 is provided at the center of the driving roller 21 , a driven connecting portion 122 is provided on the side of the driving bin 12 , the driven wheel 32 is mounted on the driven connecting portion 122 , and the rotating shaft 211 is connected to the driven wheel 32 via the driven connecting portion 122 .

[0052] In the embodiment, the driven wheel 32 is connected to the rotating shaft 211 of the driving roller 21. The driven wheel 32 rotates with the driving wheel 31, driving the rotating shaft 211 to rotate, thereby driving the driving roller 21 to rotate. The belt b1 is wound between the tensioning roller 22 and the driving roller 21. After being adjusted to a suitable tensioning degree, the friction between the belt b1 and the driving roller 21 is utilized to make the belt b1 transmit along with the rotation of the driving roller 21.

[0053] In some embodiments, an active connection portion 111 is provided on the side of the power compartment 11 , the driving wheel 31 is mounted on the active connection portion 111 , and the output end a1 of the motor a is connected to the driving wheel 31 through the active connection portion 111 .

[0054] In the embodiment, motor a is fixed in the power bin 11 and the output end a1 of motor a is connected to the active connection part 111 of the power bin 11. After motor a is started, the output end a1 of motor a drives the active wheel 31 on the active connection part 111 to rotate, and the active wheel 31 drives the driven wheel 32 to rotate through the synchronous belt 33, thereby starting the driving mechanism 2.

[0055] In some embodiments, the observation mechanism 4 includes a first transparent observation piece 41 installed on the main body 1 and covering the synchronization mechanism 3 and a second transparent observation piece 42 for covering the adjustment part 23 .

[0056] In the embodiment, the synchronization mechanism 3 and the adjustment part 23 are respectively covered with a first transparent observation piece 41 and a second transparent observation piece 42 . The staff can observe the working status of the synchronization mechanism 3 and the adjustment part 23 through the observation mechanism 4 , and remove and adjust them at any time.

[0057] This embodiment provides a belt conveyor, and the belt conveyor includes the driving device.

[0059] In some embodiments, the belt conveyor is also provided with a deviation correction mechanism b2, such as Figure 4 As shown, the belt b1 contacts the deviation-correcting mechanism b2 to transmit the transmission and limit the transmission track of the belt b1 , thereby preventing the belt b1 from moving left and right on the driving roller 21 or the tensioning roller 22 and detaching from the driving mechanism 2 .
