Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor line auxiliary equipment, and particularly relates to a belt deviation correcting device. Background Art

[0002] In cigarette production, tobacco cut and leaf storage cabinets are spread by a spreading vehicle before materials enter the cabinets. The primary function of a spreading vehicle is to evenly spread cut tobacco or other tobacco raw materials onto a designated carrier for subsequent processing and handling. Typically equipped with a conveyor belt or chain, this transports cut tobacco or other raw materials from a hopper or storage bin to the spreading area. The spreading mechanism, the core component of the spreading vehicle, is responsible for evenly spreading the cut tobacco onto the designated carrier. The spreading mechanism may include rotating drums, spreading plates, or an airflow spreading system to ensure uniform distribution of the tobacco on the carrier.

[0003] During operation, the tobacco spreading vehicle often experiences belt deviation (the center line does not coincide with the center line of the frame) due to factors such as frame processing and assembly errors, foundation level errors, belt manufacturing errors, and drive device adjustment errors. This causes uneven equipment load and even the belt to run to the outside of the frame and fail to transport materials normally. During use, the tobacco spreading vehicle may experience belt aging, deformation, and wear, which will cause the belt to deviate. Utility Model Content

[0028] To more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following describes specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the drawings described below are merely examples of the present invention. A person skilled in the art can, without inventive effort, derive other drawings and other embodiments from these drawings. Furthermore, design orientations only represent relative positional relationships between components, not absolute positional relationships.

[0029] The utility model provides a belt deviation correction device. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 , mainly includes roller 1, side plate 2, adjustment component 3 and distance measuring component 4.

[0030] See Figure 1-Figure 7 In the embodiment of the present application, a belt is sleeved on a roller 1, and the roller 1 drives the belt to move by self-rotation, thereby transporting tobacco or other tobacco raw materials. Side panels 2 are arranged at both ends of the roller 1, and the side panels 2 are rotatably connected to the roller 1. An adjustment component 3 and a distance measuring component 4 are fixed on the side of the side panel 2 away from the middle of the roller 1. There are multiple distance measuring components 4 arranged on the side panels 2. The distance measuring components 4 detect the position of the belt by contacting with the belt. The distance measuring components 4 convert the detected belt position information into an electrical signal and transmit it to the control unit. After the control unit receives the information transmitted by the distance measuring components 4, if the information transmitted by multiple distance measuring components 4 is different, the belt has shifted. The control unit controls the adjustment component 3 to adjust the belt so that the center line of the belt coincides with the center line of the frame, thereby driving the shifted belt to return to the center, thereby improving the stability of the tobacco paving vehicle in transporting materials.

[0031] Furthermore, there are multiple rollers 1 arranged in a staggered manner, the belt passes between the rollers 1 and contacts each roller 1, the number of adjustment components 3 is equal to the number of rollers 1, a first hole is opened on the side plate 2, and the two ends of the roller 1 pass through the first hole and are connected to the adjustment component 3.

[0032] In one embodiment, the first hole is a strip hole 21, and the adjustment assembly 3 includes a push rod 31. The fixed end of the push rod 31 is fixedly connected to the side plate 2, the telescopic end of the push rod 31 is rotatably connected to one end of the roller 1, and the other end of the roller 1 is rotatably connected to the support block 32. The support block 32 is fixedly connected to the side plate 2. The push rod 31 can push one end of the roller 1 so that one end of the roller 1 moves in the strip hole 21, and the entire roller 1 is offset, driving the belt in contact with the roller 1 to offset, so that the center line of the belt coincides with the center line of the frame, and then driving the offset belt to return to the center.

[0033] Specifically, the other end of the roller 1 can be connected to the support block 32 through a pin. Connecting planes are provided at both ends of the roller 1 to enhance the connection effect of the roller 1.

[0034] Preferably, the fixed end of the push rod 31 and the strip hole 21 are arranged at the same height, and the force direction of the push rod 31 is consistent with the moving direction of the roller 1, thereby shortening the adjustment time of the belt.

[0035] In one embodiment, the distance measuring assembly 4 includes a calibration part 41 and a measuring part 42. A calibration wheel 43 is provided on one side of the calibration part 41. The calibration wheel 43 is rotatably connected to the calibration part 41. After the calibration wheel 43 abuts against the edge of the belt, the measuring part 42 detects the position of the calibration part 41 to detect whether the belt is deflected. Specifically, the calibration wheel 43 can be an H-shaped wheel. The distance between the two sides of the calibration wheel 43 is greater than the thickness of the belt, which facilitates the abutment of the calibration wheel 43 with the belt and makes it easier to detect the deflection state of the belt. In addition, the calibration wheel 43 can detect the deflection of the belt at any time when the tobacco spreading vehicle is transporting materials, and can promptly drive the deviated belt to return to the right position, thereby improving the stability of the tobacco spreading vehicle in transporting materials.

[0036] Furthermore, the calibration component 41 includes a first frame body 411, a driving block 412, a connecting rod 413 and a calibration plate 414. The first frame body 411 is fixedly connected to the side panel 2. A calibration hole is arranged on the first frame body 411. The driving block 412 is arranged inside the first frame body 411, and the driving block 412 is fixedly connected to the first frame body 411. The connecting rod 413 is inserted into the calibration hole. One end of the connecting rod 413 passes through the side panel 2 and is rotatably connected to the calibration wheel 43, and the other end is fixedly connected to the calibration plate 414. The driving block 412 is used to drive the connecting rod 413 to move so that the calibration wheel 43 abuts against the belt. After the calibration wheel 43 abuts against the belt, the measuring component 42 detects the position of the calibration plate 414. If the positions detected by multiple ranging components 4 are inconsistent, it means that the belt is offset.

[0037] Since the connecting rod 413 is inserted into the calibration hole, the contact area between the first frame 411 and the connecting rod 413 is small, and the connecting rod 413 may shake. In order to improve the stability of the connecting rod 413, a linear bearing is fixedly connected to the side of the calibration hole of the first frame 411 away from the connecting rod 413, and the connecting rod 413 is sleeved inside the linear bearing.

[0038] Specifically, the drive block 412 includes a motor 4121, a connecting wire 4123, and a calibration bearing 4122. The motor 4121 is fixed inside the first frame 411. Two motors 4121 are arranged symmetrically along the centerline of the first frame 411. The calibration bearing 4122 is fixed to the motor shaft of the motor 4121. A second hole is opened on the surface of the first frame 411. One end of the connecting wire 4123 is fixed to the calibration bearing 4122, and the other end passes through the second hole and is tied to the edge of the calibration plate 414. The rotation of the motor 4121 causes the connecting wire 4123 to retract, pulling the calibration plate 414 and the calibration wheel 43 toward the direction of the belt, causing the calibration wheel 43 to abut the belt edge, thereby detecting the belt's deflection. When the belt deflects and the calibration wheel 43 moves toward the first frame 411, the calibration plate 414 moves away from the motor 4121. Since the connecting wire 4123 is fixed to the calibration bearing 4122, the calibration bearing 4122 rotates, releasing the connecting wire 4123. It should be noted that the calibration bearing 4122 can be a tapered roller bearing, a deep groove ball bearing, or the like.

[0039] Preferably, a V-shaped groove is provided on the calibration bearing 4122, and the connecting wire 4123 can be embedded inside the V-shaped groove. The V-shaped structure of the groove can make the connecting wire 4123 fall stably at the bottom of the groove when it starts to shrink. In the subsequent shrinkage process, the connecting wires 4123 are stacked layer by layer, thereby avoiding the connecting wires 4123 from being entangled with each other.

[0040] Furthermore, the measuring part 42 includes a second frame 421 and a sensor. The second frame 421 is arranged on the periphery of the first frame 411, and the second frame 421 is fixedly connected to the side panel 2. The sensor is fixed on the second frame 421. The sensor is used to detect the distance between the sensor and the calibration plate 414. When the positions detected by each sensor are inconsistent, it means that the belt is offset.

[0041] Furthermore, the distance measuring component 4 further includes a reinforcing rib 44 , one end of which is fixedly connected to the first frame 411 , and the other end of which is fixedly connected to the second frame 421 .
