In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0068] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0070] The present invention provides a guide machine for installing the transmission roller of the belt conveyor for leaf threshing and redrying, referring to Figure 1 , Figure 3and Figure 6 , comprising a movable base 1, a lifting mechanism 2 and a guide mechanism 3 which are arranged in sequence from bottom to top and are suitable for providing correct guidance for the transmission roller 6, wherein the guide mechanism 3 is also provided with a pressure detection mechanism 5 which is suitable for detecting the real-time pressure of the transmission roller 6. The present invention realizes the detection and feedback of the deflection of the transmission roller 6 of the leaf threshing and re-roasting belt conveyor through the above arrangement, and can automatically correct the guide of the transmission roller 6.

[0071] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to 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 driving shaft of the first driving member 32. For illustration, 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 driving mode of a servo motor + a ball screw. 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 arranged 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 arc surface guide block 37 is detachably connected to the guide fixed block 35 , and the pressure detection mechanism 5 is disposed in the central fixed block 36 and connected to the arc surface 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 has not shifted, 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 has shifted, the pressure data detected by the pressure detection mechanism 5 will fluctuate greatly. If the shift 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 shift 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, arc-surface guide blocks 37 are provided on both sides of the central fixed block 36, so that two transmission shafts can be detected at the same time. In addition, when detecting and correcting the transmission roller 6, the transmission roller 6 installation guide machine described in the present invention can be set between different transmission rollers 6, which is conducive to saving the time of detecting and correcting different transmission rollers 6 of the present invention. In addition, when the transmission roller 6 installation guide machine described in the present invention is provided on both sides of a transmission roller 6, the transmission roller 6 is clamped in the middle of the two arc-surface guide blocks 37, and the arc-surface guide block 37 can directly correct the deviation of the transmission roller 6 no matter in which direction it deflects.

[0072] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to Figure 3 , a sensor slot 36.1 is provided in the central fixing block 36, and the pressure detection mechanism 5 includes a pressure detection sensor 51 provided in the sensor slot 36.1, and the pressure detection sensor 51 is connected to the arc surface guide block 37 through a detection plate 52. As an 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 performance, so as to more accurately transmit the pressure on the arc surface guide block 37 to the pressure detection sensor 51.

[0073] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to Figure 2 , Figure 7 and Figure 8 , the guide fixing block 35 is provided with a slide rail 35.1 perpendicular to the extending direction of the guide groove 31, and the bottom of the arc surface guide block 37 is provided with a slider 37.1 matching the slide rail 35.1, and the slide rail 35.1 is slidably connected to the slider 37.1. As an illustration, generally speaking, the models of the transmission roller 6 used in the threshing and re-roasting conveyor belt machines of different models are different. Therefore, a suitable arc surface guide block 37 can be selected according to the model of the threshing and re-roasting conveyor belt machine to match the curvature of the transmission roller 6. Although different arc surface guide blocks 37 have differences in shape and curvature, the slider 37.1 at the bottom should adopt a standardized design, so that the arc surface guide block 37 is more modular and convenient for operators to replace the arc surface guide block 37. In a specific embodiment, the slider 37.1 and the slide rail 35.1 are T-shaped sliders 37.1 and T-shaped sliders 37.1, which can increase the friction between the slider 37.1 and the slide rail 35.1 and improve the stability of the arc surface guide block 37 when in use.

[0074] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to Figure 3 and Figure 4The guide groove 31 is also provided with a guide rod 33 arranged along the extending direction of the guide groove 31, and the adapter block is provided with a guide rod through groove 34.1 matching the guide rod 33, and the guide rod 33 is slidably connected to the guide rod through groove 34.1. As an illustration, the guide rod 33 can provide guidance for the first driving member 32 and provide stability for the guide block 34 during movement. Generally speaking, a guide rod 33 is respectively provided on both sides of the first driving member 32, so that the stability of the guide block 34 during movement is further improved.

[0075] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to Figure 1 and Figure 5 , the guide mechanism 3 also 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 a connecting plate 42 disposed at both ends of the truss 41 and perpendicular to the truss 41, and the connecting plate 42 is detachably connected to the side plate of the corresponding guide groove 31. As an illustration, the positioning frame 4 is in a concave shape, 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 plane 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.

[0076] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to Figure 1 and Figure 5, the connecting plate 42 is provided with a first fixing hole 42.1, the side plate of the guide groove 31 is provided with a plurality of second fixing holes 31.1 arranged in sequence along the extending direction of the guide groove 31, and the first fixing hole 42.1 and the second fixing hole 31.1 are connected by fixing screws 43. As an illustration, the distance that the guide block 34 needs to move can be inferred according to the length of the transmission roller 6 of different leaf threshing and redrying conveyor belt machines, and then two positioning frames 4 can be set on the guide groove 31 according to the distance to limit the moving distance of the guide block 34, and then two second fixing holes 31.1 with a distance matching the length of the transmission roller 6 are selected, and the first fixing hole 42.1 on the connecting plate 42 is aligned with the second fixing hole 31.1, and finally the connecting plate 42 and the side plate of the guide groove 31 are fixedly connected by fixing screws 43. Through the above arrangement, the present invention realizes the limiting of the guide slider 37.1, and can adjust the moving distance of the guide slider 37.1 according to the length of the transmission roller 6 of different models of leaf threshing and redrying belt conveyors.

[0077] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to Figure 1 , Figure 2 and Figure 5 , an extension plate 35.2 is provided on the side of the guide fixing block 35 that is in the same extension direction as the guide groove 31, a signal transmitter 35.3 is provided on the extension plate 35.2, and a receiving plate 44 is provided on the side of the truss 41 close to the extension plate 35.2, and a receiver is provided on the receiving plate 44. As an illustration, the signal transmitter 35.3 can be an infrared transmitter or an RFID transmitter, preferably an infrared transmitter, and the signal receiver 44.1 can be an infrared receiver or an RFID receiver, preferably an infrared receiver. In a specific embodiment, the guide fixing block 35 is provided with two extension plates 35.2, one in front and one in back, and the guide groove 31 is provided with two positioning frames 4, one in front and one in back, where "one in front and one in back" is based on the extension direction of the guide groove 31, and the positioning frames 4 are provided with receiving plates 44. When in 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 for the transmission roller 6 and improving the degree of automation of the device.

[0078] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to 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 top of the push cylinder 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 top of the push cylinder 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 present invention 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 present invention.

[0079] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to 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 guiding mechanism 3 and the pressure detection mechanism 5.

[0080] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to Figure 1 The movable base is provided with a traction rod 13, and a universal wheel 11 is also provided below the movable base. When in use, the operator can pull the traction rod 13 to move the movable base below the transmission roller 6 to be detected.

[0081] In the guide machine for installing the driving roller of the belt conveyor for leaf threshing and redrying provided by the present invention, refer to Figure 1 , the movable base is provided with a controller 14, the controller 14 is connected with the lifting mechanism 2, the guide mechanism 3 and the pressure detection mechanism 5 through a circuit, and the controller 14 can monitor and control the lifting mechanism 2, the guide mechanism 3 and the pressure detection mechanism 5. Through the above arrangement, the present invention enables the operator to control each actuator and monitor the pressure data fed back by the pressure detection mechanism 5 in real time, and can make a guidance reference based on the pressure data, so as to facilitate the fine adjustment of the transmission roller 6 at a later stage.

[0082] This embodiment also provides a method for using a guide machine for installing a drive roller of a leaf threshing and redrying belt conveyor, which includes at least the following steps:

[0083] Step 1) Move the movable base 1 to below the drive roller 6 to be tested on the leaf threshing and re-roasting belt conveyor. Further, the operator can pull the traction rod 13 to move the movable base to below the drive roller 6 to be tested.

[0084] Step 2) The guide mechanism 3 is raised to one side of the transmission roller 6 by the lifting mechanism 2. Further, the second driving motor drives the scissor-type lifting frame 22 to rise upward, and the guide mechanism 3 is raised to one side of the transmission roller 6.

[0085] Step 3) The guide mechanism 3 is close to the transmission roller 6 and moves along the extension direction of the transmission roller 6. During the movement, the pressure detection mechanism 5 detects the pressure of the transmission roller 6 in real time. Further, the position of the movable base 1 is adjusted so that the arc surface guide block 37 in the guide mechanism 3 can be close to the transmission roller 6 to be detected, and then the first drive motor is started. The first drive motor drives the guide block 34 to move along the extension direction of the guide groove 31. At the same time, the arc surface guide block 37 also moves close to the transmission roller 6. During the movement of the arc surface guide block 37, the pressure detection sensor 51 obtains the pressure of the transmission roller 6 on the arc surface guide block 37 in real time, and feeds back the pressure data to the controller 14. The operator can manually adjust the transmission roller 6 according to the pressure data on the controller 14. When the extension plate 35.2 moves to the top of 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, and the signal generator feeds back the data to the controller 14, and the controller 14 can automatically issue the first drive motor to stop driving. When the transmission roller 6 installation guide machine described in the present invention 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 along the extension direction of the transmission roller 6 at the same time. 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 deviation correction of the arc guide block 37.

[0086] 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 substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
