Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for installing transmission rollers, in particular to a guide machine for installing transmission rollers of a leaf threshing and redrying belt conveyor. Background Art

[0002] The leaf threshing and re-drying process is a tobacco processing process that requires the tobacco leaves to be broken up, separated, cleaned, dried, and re-roasted from their original state. Since the process is long and complicated, belt conveyors are required to transport raw materials between each link.

[0003] The belt conveyors used in tobacco processing are mostly horizontal smooth belt conveyors. The belts are driven by transmission rollers. When installing this type of belt conveyor, the transmission rollers need to be guided and calibrated to avoid deviation of tobacco raw materials on the belts. When installing and guiding the transmission rollers, a guide plate with arc-shaped concave edges is often used. The guide plate is inserted between the two sets of transmission rollers and pushed along the gap between the transmission rollers. If there is obvious resistance, it means that the transmission rollers are skewed and the guidance needs to be adjusted. In actual use, it relies more on the experience and feel of the installation workers, and the operation consumes a lot of physical strength. It does not have the function of automatic guidance and feedback.

[0004] In summary, there is an urgent need for a transmission roller installation and guide machine that can detect and provide feedback on the deflection of the transmission roller and can automatically correct the guide of the transmission roller. Utility Model Content

[0064] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of the present invention, it should be noted that the orientations or positional relationships indicated by the terms "left side", "right side", "upper side", "lower side", "above", "below", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0065] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0066] In addition, in the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0067] The utility model provides a guide machine for installing the transmission roller of the belt conveyor for threshing and redrying leaves. Figure 1 、 Figure 3 and Figure 6The utility model comprises, arranged from bottom to top, a movable base 1, a lifting mechanism 2, and a guide mechanism 3 for providing correct guidance for a drive roller 6. The guide mechanism 3 is also equipped with a pressure detection mechanism 5 for detecting the real-time pressure of the drive roller 6. Through this arrangement, the utility model detects and provides feedback on the deflection of the drive roller 6 of the threshing and re-roasting belt conveyor, and can automatically correct the deflection of the drive roller 6.

[0068] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 1 and Figure 4 The guide mechanism 3 includes a guide groove 31, a first driving member 32 disposed in the guide groove 31, and a guide block 34 connected to the drive shaft of the first driving member 32. For example, the first driving member 32 drives the guide block 34 to move along the extension direction of the guide groove 31. The first driving member 32 can be selected from any one of a stepping motor, a DC reduction motor, or a servo motor. Preferably, the first driving member 32 can adopt a servo motor + ball screw drive mode. Figure 3 The guide block 34 is provided with a guide fixing block 35, and the guide fixing block 35 is provided with a central fixing block 36 and an arcuate guide block 37. Generally speaking, the central fixing block 36 is provided at the central position of the upper surface of the guide fixing block 35, and the arcuate guide block 37 is located on the side perpendicular to the extension direction of the central fixing block 36 and the guide groove 31, and the arcuate surface of the arcuate guide block 37 faces away from the central fixing block 36. Figure 3 and Figure 6 The arcuate guide block 37 is detachably connected to the guide fixed block 35 , and the pressure detection mechanism 5 is arranged in the central fixed block 36 and is connected to the arcuate guide block 37 through the detection plate 52 . When the guide mechanism 3 is in use, the arc surface guide block 37 is pressed against the surface of the transmission roller 6 to be detected, and then the first drive motor is started. The first drive motor will drive the guide block 34 to move along the extension direction of the guide groove 31, that is, the extension direction of the transmission roller 6. During the movement, the pressure detection mechanism 5 detects the pressure applied by the transmission roller 6 to the arc surface guide mechanism 3 in real time. If the position of the transmission roller 6 does not deviate, the pressure data detected by the pressure detection mechanism 5 should remain stable within a certain range; if the position of the transmission roller 6 deviates, the pressure data detected by the pressure detection mechanism 5 will fluctuate greatly. If the deviation occurs in the direction close to the arc surface guide block 37, the pressure data will gradually increase, otherwise, the pressure data will gradually decrease; when the deviation occurs in the direction close to the arc surface guide block 37, the resistance generated by the arc surface guide block 37 during movement will push the transmission roller 6 away from the arc surface guide block 37, thereby correcting the position of the transmission roller 6. In a specific embodiment, refer to Figure 6, curved guide blocks 37 are provided on both sides of the central fixed block 36, allowing for simultaneous testing of both transmission shafts. Furthermore, when testing and correcting the transmission rollers 6, the transmission roller 6 mounting guide described in the present invention can be installed between different transmission rollers 6, saving time in testing and correcting the deviation of different transmission rollers 6. Furthermore, when the transmission roller 6 mounting guide described in the present invention is installed on both sides of a transmission roller 6, the transmission roller 6 is clamped between the two curved guide blocks 37. Regardless of the direction in which it deflects, the curved guide blocks 37 can directly correct its deviation.

[0069] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 3 The central fixing block 36 is provided with a sensor slot 36.1. The pressure detection mechanism 5 includes a pressure detection sensor 51 disposed in the sensor slot 36.1. The pressure detection sensor 51 is connected to the arcuate guide block 37 via a detection plate 52. For illustration, the pressure detection sensor 51 can be a conventional pressure sensor, and the pressure detection plate 52 can be made of a material with good force transmission properties to more accurately transmit the pressure exerted on the arcuate guide block 37 to the pressure detection sensor 51.

[0070] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 2 、 Figure 7 and Figure 8 The guide fixing block 35 is provided with a slide rail 35.1 extending perpendicularly to the direction in which the guide groove 31 extends. A slider 37.1 is provided at the bottom of the cambered guide block 37 to match the slide rail 35.1. The slide rail 35.1 and the slider 37.1 are slidably connected. For illustration, generally speaking, different models of leaf threshing and redrying conveyor belt conveyors use different models of drive rollers 6. Therefore, a suitable cambered guide block 37 can be selected based on the model of the leaf threshing and redrying conveyor belt conveyor to match the curvature of the drive roller 6. Although different cambered guide blocks 37 vary in shape and curvature, the slider 37.1 at the bottom should adopt a standardized design to make the cambered guide block 37 more modular and facilitate replacement of the cambered guide block 37 by the operator. In one specific embodiment, the slider 37.1 and the slide rail 35.1 are T-shaped sliders 37.1 and 37.1, which can increase the friction between the slider 37.1 and the slide rail 35.1 and improve the stability of the cambered guide block 37 during use.

[0071] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 3 and Figure 4The guide slot 31 is further provided with a guide rod 33 extending along the guide slot 31. The adapter block is provided with a guide rod through-slot 34.1 that matches the guide rod 33. The guide rod 33 is slidably connected to the guide rod through-slot 34.1. For illustration, the guide rod 33 can provide guidance for the first drive member 32 and provide stability for the guide block 34 during movement. Generally speaking, a guide rod 33 is provided on each side of the first drive member 32 to further enhance the stability of the guide block 34 during movement.

[0072] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 1 and Figure 5 The guide mechanism 3 further includes a positioning frame 4 disposed on the guide groove 31 and detachably connected to the guide groove 31. The positioning frame 4 includes a truss 41 disposed above the guide groove 31 and connecting plates 42 disposed at both ends of the truss 41 and perpendicular to the truss 41. The connecting plates 42 are detachably connected to the corresponding side plates of the guide groove 31. As an illustration, the positioning frame 4 is in the shape of a concave character, and the truss 41 can be erected above the guide groove 31. Generally speaking, the height of the guide block 34 plus the guide fixing block 35 will be higher than the highest horizontal surface of the guide groove 31. Therefore, when the first driving member 32 drives the guide block 34 to move a certain distance, it will touch the truss 41, thereby limiting the movement of the guide block 34 and the guide fixing block 35. In a specific embodiment, two positioning frames 4 are provided on the guide groove 31, one in front and one behind. The "one in front and one behind" here is based on the extension direction of the guide groove 31. The guide block 34 is provided between the two positioning frames 4, and the guide block 34 moves within the range framed by the two positioning frames 4.

[0073] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 1 and Figure 5The connecting plate 42 is provided with a first fixing hole 42.1, and the side plates of the guide trough 31 are provided with a plurality of second fixing holes 31.1 arranged sequentially along the extending direction of the guide trough 31. The first fixing holes 42.1 and the second fixing holes 31.1 are connected by fixing screws 43. For example, the required movement distance of the guide block 34 can be inferred based on the length of the drive roller 6 of different leaf threshing and redrying conveyor belts. Based on this distance, two positioning brackets 4 can be provided on the guide trough 31 to limit the movement distance of the guide block 34. Subsequently, two second fixing holes 31.1 with a distance matching the length of the drive roller 6 are selected, and the first fixing holes 42.1 on the connecting plate 42 are aligned with the second fixing holes 31.1. Finally, the connecting plate 42 and the side plates of the guide trough 31 are fixedly connected by fixing screws 43. Through the above arrangement, the present invention achieves position limiting of the guide slider 37.1 and can adjust the movement distance of the guide slider 37.1 according to the length of the drive roller 6 of different leaf threshing and redrying conveyor belts.

[0074] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 1 、 Figure 2 and Figure 5 An extension plate 35.2 is provided on the side of the guide fixing block 35 extending in the same direction as the guide slot 31. A signal transmitter 35.3 is provided on the extension plate 35.2. A receiving plate 44 is provided on the side of the truss 41 near the extension plate 35.2. A receiver is provided on the receiving plate 44. By way of illustration, the signal transmitter 35.3 can be an infrared transmitter or an RFID transmitter, preferably an infrared transmitter. The signal receiver 44.1 can be an infrared receiver or an RFID receiver, preferably an infrared receiver. In a specific embodiment, two extension plates 35.2 are provided on the guide fixing block 35, one in front of the other. Two positioning brackets 4 are provided on the guide slot 31, one in front of the other. The "one in front of the other" here is based on the extending direction of the guide slot 31. Each positioning bracket 4 is provided with a receiving plate 44. During use, when the first driving member 32 drives the guide block 34 to move a certain distance along the extension direction of the guide groove 31, the extension plate 35.2 will move to the top of the receiving plate 44. At this time, the infrared signal emitted by the signal transmitter 35.3 on the extension plate 35.2 will be received by the signal receiver 44.1 on the receiving plate 44, so that the signal receiver 44.1 can transmit the signal to the external system to issue an instruction to the first driving member 32 to stop driving, thereby improving the detection and correction rate of the guide mechanism 3 on the transmission roller 6, and at the same time improving the degree of automation of the device.

[0075] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 1, the lifting mechanism 2 includes a second driving member 21 and a scissor-type lifting frame 22 connected to the driving shaft of the second driving member 21. As an illustration, the second driving member 21 is selected from any one of a stepping motor, a DC reduction motor, a servo motor or a push cylinder, preferably a push cylinder. When in use, the push cylinder is started, and when the push cylinder head is pushed upward, the scissor-type lifting frame 22 is stretched open, and the guide mechanism 3 moves upward under the push of the scissor-type lifting frame 22; when the push cylinder head is retracted downward, the scissor-type lifting frame 22 is retracted, and the guide mechanism 3 moves downward under the push of the scissor-type lifting frame 22. Through the above-mentioned arrangement, the utility model realizes the adjustment of the actual height of the guide mechanism 3, and can match the transmission rollers 6 of different heights, thereby improving the applicability of the utility model.

[0076] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 1 The movable base is provided with a power cord 12, and the power cord 12 is used to supply power to the lifting mechanism 2, the guide mechanism 3 and the pressure detection mechanism 5.

[0077] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 1 The movable base is provided with a traction rod 13, and a universal wheel 11 is also provided below the movable base. During use, the operator can pull the traction rod 13 to move the movable base below the transmission roller 6 to be detected.

[0078] The utility model provides a belt conveyor for threshing and redrying leaves. The drive roller is installed in the guide machine. Figure 1 The movable base is provided with a controller 14, which is connected to the lifting mechanism 2, the guide mechanism 3, and the pressure detection mechanism 5 via an electrical circuit. The controller 14 can monitor and control the lifting mechanism 2, the guide mechanism 3, and the pressure detection mechanism 5. Through the above-described arrangement, the present invention enables an operator to control each actuator and monitor the real-time pressure data fed back by the pressure detection mechanism 5. This pressure data can be used as a guide reference, facilitating fine-tuning of the transmission roller 6 later.

[0079] This embodiment also provides a method for using a guide machine for installing a drive roller of a leaf threshing and redrying belt conveyor, including at least the following steps:

[0080] Step 1) Move the movable base 1 to below the transmission roller 6 to be tested on the threshing and redrying belt conveyor. Further, the operator can pull the traction rod 13 to move the movable base to below the transmission roller 6 to be tested.

[0081] Step 2) The guide mechanism 3 is raised to one side of the transmission roller 6 by the lifting mechanism 2. Further, the second drive motor drives the scissor lift frame 22 to rise upward, and the guide mechanism 3 is raised to one side of the transmission roller 6.

[0082] Step 3) The guide mechanism 3 is in close contact with the transmission roller 6 and moves along the extension direction of the transmission roller 6. During this movement, the pressure detection mechanism 5 detects the pressure of the transmission roller 6 in real time. Furthermore, the position of the movable base 1 is adjusted so that the curved guide block 37 in the guide mechanism 3 is in close contact with the transmission roller 6 to be detected. The first drive motor is then activated, driving the guide block 34 to move along the extension direction of the guide groove 31. Simultaneously, the curved guide block 37 also moves in close contact with the transmission roller 6. During the movement of the curved guide block 37, the pressure detection sensor 51 detects the pressure of the transmission roller 6 on the curved guide block 37 in real time and feeds this pressure data back to the controller 14. The operator can manually adjust the transmission roller 6 based on the pressure data from the controller 14. When the extension plate 35.2 moves above the receiving plate 44, the signal emitted by the signal transmitter 35.3 on the extension plate 35.2 is received by the signal receiver 44.1 on the receiving plate 44. The signal generator feeds this data back to the controller 14, which then automatically instructs the first drive motor to stop. When the transmission roller 6 installation guide machine described in the utility model is deployed on both sides of a transmission roller 6, the first driving members 32 on both sides are started at the same time, driving the guide block 34 and the arc guide block 37 to move simultaneously along the extension direction of the transmission roller 6. At this time, no matter in which direction the transmission roller 6 deviates, it will be pushed in the opposite direction by the resistance generated by the movement of the arc guide block 37, thereby realizing automatic correction of the arc guide block 37.

[0083] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
