Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to an automated packaging conveyor for the production of roasted gluten. Background Technology

[0002] Roasted gluten is a food made from gluten. It is spiral-shaped and has a chewy and crisp texture, making it popular with consumers. To meet market demand, the production process of roasted gluten has been automated. From raw material production, forming, to conveying and packaging, there are corresponding automated equipment involved. Taking conveying and packaging as an example, the conveyor belt packaging equipment used can meet the needs of long-distance and uninterrupted conveying, reducing labor intensity while maintaining continuous and efficient production.

[0003] However, conveyor belt packaging equipment also has some defects. For example, during long-term use, the internal conveyor belt may deviate due to factors such as vibration and uneven material distribution. As the deviation increases, there is a greater probability that the material output from the top of the conveyor belt will fall to the ground, which will lead to material contamination and increase production costs. Secondly, long-term deviated conveying will also shorten the life of the conveyor belt itself and increase the operating cost of the equipment. Summary of the Invention

[0004] This invention provides an automated packaging conveyor for the production of roasted gluten, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated packaging conveyor for roasted gluten production, comprising a workbench, a conveyor belt mechanism mounted on the top of the workbench, an offset measuring mechanism, and a detection triggering mechanism. The conveyor belt mechanism includes a conveyor belt and a power assembly. Drive rollers are fitted inside both sides of the conveyor belt, and roller frames are fitted at both ends of each drive roller. A clearance gap is provided between the two roller frames. The power assembly is mounted on one roller frame and drives the corresponding drive roller. XZ adjustment platforms are provided on both the front and rear ends of the top of the workbench, and these platforms are driven by the roller frames and can drive the roller frames to perform vertical or horizontal displacement. The offset measuring mechanism includes a first support frame located at the bottom of the conveyor belt. A second support frame is slidably connected to the top rear end of the first support frame. Several laser sensing components are arranged on the top of the second support frame, each of which is movably sleeved with the bottom side of the conveyor belt. A second lead screw transmission structure is connected to the middle of the second support frame. The laser sensing components can determine the offset distance of the conveyor belt by whether they receive a signal during the linear displacement of the second support frame driven by the second lead screw transmission structure. The detection triggering mechanism includes a curved receiving plate located outside the front and rear ends of the conveyor belt. A pressure sensor and a linkage structure are respectively arranged inside and outside the top of the curved receiving plate. After receiving the unloading material, the linkage structure can synchronously apply pressure to the pressure sensor and trigger the offset measuring mechanism by the pressure change of the pressure sensor.

[0006] Preferably, the power assembly includes a first brake servo motor, a synchronous belt, and two synchronous pulleys. The two synchronous pulleys are respectively fitted inside the top and bottom of the synchronous belt, and one of the synchronous belts is connected to the output end of the first brake servo motor mounted on the surface of the roller frame, while the other synchronous belt is mounted on the end of one end of the transmission roller.

[0007] Preferably, the end of the transmission roller is fitted to the top structure of the corresponding roller frame via a self-aligning bearing. Both ends of the transmission roller are provided with clearance space, and an angle sensor coaxial with the transmission roller is installed in the clearance space. A protective sleeve is installed on the top of the roller frame at the front end of the transmission roller, which is movably fitted with the corresponding end of the transmission roller. A conductive slip ring is installed in the protective sleeve, which is movably fitted with the end of the transmission roller and electrically connected to the angle sensor.

[0008] Preferably, the XZ adjustment platform includes a positioning support and a movable support. The movable support is snapped into the interior of the positioning support. Both the positioning support and the movable support are provided with a first lead screw transmission structure. The two first lead screw transmission structures respectively transmit horizontal displacement to the movable support and vertical displacement to the roller frame. The first lead screw transmission structure includes a second brake servo motor, a first lead screw, a first nut, and a first reducer. The second brake servo motor and the first reducer are mutually connected, and the output end of the first reducer is connected to one end of the first lead screw. The first nut is threaded onto the surface of the first lead screw, and a linkage plate is installed between the first nut and the bottom of the roller frame or the side of the movable support, and synchronous displacement is transmitted through the linkage plate.

[0009] Preferably, the XZ adjustment platform further includes two limiting guide rods respectively installed on the front and rear ends of the bottom of the roller frame, and electromagnets respectively installed on the front and rear ends of the top of the positioning support. The bottom of the limiting guide rods is snapped through the top structure of the movable support, and the electromagnets are magnetically connected to a reinforcing plate fixed on the bottom surface of the roller frame.

[0010] Preferably, the laser sensing component consists of a laser emitter and a laser receiver, both of which are mounted on the rear end structure at the top of the second support frame. The second lead screw drive structure includes a third brake servo motor, a second reducer, a second lead screw, and a second nut. The third brake servo motor and the second reducer are mutually connected and are both mounted on the top rear end of the first support frame. The inner and outer sides of the second nut are threaded to the surface of the second lead screw and the inner side of the second support frame, respectively. One end of the second lead screw is connected to the output end of the second reducer. The bottom of the second support frame is engaged with a slide rail mounted on the top rear end of the first support frame.

[0011] Preferably, the bottom of the curved storage plate is fixed to the top of the first support frame. The linkage structure includes a pressure-sensing plate, which is movably sleeved inside the curved storage plate. Several T-shaped rods and detection rods penetrating the curved storage plate are arranged and installed at the bottom of the pressure-sensing plate. The detection rods are aligned with pressure sensors installed on the inner wall of the top of the curved storage plate. A return spring is fitted on one end of the T-shaped rod, and the two ends of the return spring are respectively fixed to the inner wall of the top of the curved storage plate and the end surface of one end of the T-shaped rod.

[0012] Preferably, the pressure-sensitive plate includes three pressure-sensitive plates, and the three pressure-sensitive plates divide the outer space of the top of the curved storage plate into a left-biased area, a middle area and a right-biased area from left to right. Each of the three pressure-sensitive plates has at least one T-shaped rod, a reset spring, a pressure sensor and a detection rod, and a curved spring sheet is installed between two adjacent pressure-sensitive plates.

[0013] Preferably, the bottom of each of the three pressure-sensing plates is provided with several damping pads installed on the top surface of the curved storage plate. The damping pads, in conjunction with the reset spring, dampen and buffer the vibration and impact of the pressure sensor beyond the initial pressure, thereby extending the service life of the pressure sensor and reducing the cost of use.

[0014] A method for using an automated packaging conveyor for roasted gluten production includes the following operating steps:

[0015] S1, Normal material feeding

[0016] The drive rollers associated with the power unit rotate synchronously, enabling the conveyor belt to rotate automatically and transport materials with the support of another drive roller and four roller frames;

[0017] S2, Abnormal material release

[0018] During the material conveying process of the conveyor belt, if either of the two curved receiving plates located at the front and rear ends of the conveyor belt receives material, it is determined to be an abnormality. When material is received, the linkage structure bears the weight and applies pressure to the pressure sensor synchronously. Subsequently, the offset ranging mechanism is triggered by the pressure sensor changing pressure.

[0019] S3, Offset Distance Measurement

[0020] After the offset measuring mechanism is triggered, the second lead screw drive structure drives the second support frame and multiple laser sensing components to automatically move away from the corresponding side of the conveyor belt. Simultaneously, the displacement distance value output by the second lead screw drive structure when each laser sensing component receives a signal is recorded. The change pattern of the multiple displacement distance values ​​is used to determine whether the conveyor belt has deviated.

[0021] S4, Offset Detection

[0022] The conveyor belt is determined by the changing pattern of multiple displacement distance values. If multiple displacement distance values ​​are roughly the same, it means that the conveyor belt is still in the designated conveying position. If multiple displacement distance values ​​show an increasing or decreasing phenomenon, it means that the conveyor belt has shifted.

[0023] S5, Reset Adjustment

[0024] By readjusting the transmission positions of the two drive rollers and the four roller frames through the four XZ adjustment platforms, the conveyor belt is restored to the correct conveying state.

[0025] S6, Re-inspection Feedback

[0026] Repeat steps S3 and S4 above to check if the conveyor belt has been successfully restored. If not, repeat all the above steps until the conveyor belt is restored to the correct conveying state. If the conveyor belt is successfully restored, the conveyor belt can continue to be used normally.

[0027] The present invention has the following beneficial effects:

[0028] 1. This automated packaging conveyor for roasted gluten production, through the coordinated operation of a conveyor belt mechanism, an offset measuring mechanism, and a detection triggering mechanism, not only meets the requirements for long-distance, uninterrupted automatic conveying and packaging of roasted gluten materials, but also, in the event of material spillage during the conveyor belt process, the detection triggering mechanism covers and collects the roasted gluten material that has detached from the conveyor belt to prevent contamination and waste. At the same time, the detection triggering mechanism will also be activated in real time based on changes in pressure detection, enabling it to automatically detect the offset of the side of the conveyor belt, promptly identify abnormalities, and reduce losses.

[0029] 2. The automated packaging conveyor for roasted gluten production has a reset mechanism formed by four roller frames and their corresponding XZ adjustment platforms. After acquiring data from the offset measuring mechanism and two tilt sensors and performing comprehensive calculations, the four XZ adjustment platforms can control the corresponding roller frames to automatically lift or automatically move horizontally, thereby restoring the conveyor belt to its normal conveying state.

[0030] 3. The automated packaging conveyor for roasted gluten production is equipped with a detection triggering mechanism. The pressure-sensing plate inside the mechanism can mark the position of roasted gluten material falling off the conveyor belt by sensing pressure in different areas. This further optimizes the triggering conditions of the offset measuring mechanism, reduces the number of useless operations of the offset measuring mechanism, and lowers the overall operating cost of the device.

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-5 An automated packaging conveyor for roasted gluten production includes a workbench 1, a conveyor belt mechanism, an offset measuring mechanism, and a detection triggering mechanism set on the top of the workbench 1. The conveyor belt mechanism includes a conveyor belt 2 and a power component 5. Transmission rollers 3 are fitted inside both sides of the conveyor belt 2, and roller frames 4 are fitted at both ends of the transmission rollers 3. A clearance gap is provided between the two roller frames 4. The power component 5 is set on one roller frame 4 and is connected to the corresponding transmission roller 3 for transmission.

[0045] The power assembly 5 includes a first brake servo motor 51, a synchronous belt 52, and two synchronous pulleys 53. The two synchronous pulleys 53 are respectively fitted inside the top and bottom of the synchronous belt 52. One of the synchronous belts 52 is connected to the output end of the first brake servo motor 51 mounted on the surface of the roller frame 4. The other synchronous belt 52 is mounted on the end of one end of the transmission roller 3. This provides a means of powering the two transmission rollers 3 to rotate and output power in coordination with the transmission conveyor belt 2, thus initially improving the automation effect of the overall device.

[0046] The end of the drive roller 3 is fitted to the top structure of the corresponding roller frame 4 via a self-aligning bearing. Both ends of the drive roller 3 are provided with clearance space, and an inclination sensor 18 coaxial with the drive roller 3 is installed in the clearance space. This satisfies the requirement to detect the height change of the two drive rollers 3 during continuous use. The top of the roller frame 4 at the front end of the drive roller 3 is equipped with a protective sleeve 19 that is movably fitted with the corresponding end of the drive roller 3. A conductive slip ring 17 that is movably fitted with the end of the drive roller 3 and electrically connected to the inclination sensor 18 is installed in the protective sleeve 19. This ensures the power supply to the inclination sensor 18 while the drive roller 3 rotates without interference.

[0047] In use, to meet the automatic output requirements of conveyor belt 2, the first brake servo motor 51 is started, and the first brake servo motor 51 drives the corresponding synchronous belt 52 to rotate synchronously. Then, under the linkage of synchronous pulley 53 and another synchronous belt 52, the transmission roller 3 corresponding to the power component 5 will also rotate synchronously. Similarly, under the linkage support of another transmission roller 3, the conveyor belt 2 will be driven and rotated in a cycle for output.

[0048] The height change of the two drive rollers 3 during use can be calculated by the horizontal tilt angle fed back in real time by the two tilt sensors 18;

[0049] Please see Figure 1 , Figure 6 The workbench 1 is equipped with XZ adjustment platforms 6 on both sides of the front and rear ends of the top, and the XZ adjustment platforms 6 are connected to the roller frame 4 and can drive the roller frame 4 to make vertical or horizontal displacement.

[0050] The XZ adjustment platform 6 includes a positioning support 61 and a movable support 62. The movable support 62 is snapped into the interior of the positioning support 61. Both the positioning support 61 and the movable support 62 are equipped with a first lead screw transmission structure 63. The two first lead screw transmission structures 63 respectively transmit horizontal displacement to the movable support 62 and vertical displacement to the roller frame 4. This satisfies the requirement for the roller frame 4 to automatically reset and adjust the conveyor belt 2 in different directions after it has shifted. This ensures the adjustment accuracy while also reducing the difficulty of operation for the operator and improving the efficiency of the reset and adjustment.

[0051] The first lead screw transmission structure 63 includes a second brake servo motor 631, a first lead screw 632, a first nut 633, and a first reducer 634. The second brake servo motor 631 and the first reducer 634 are mutually connected, and the output end of the first reducer 634 is connected to one end of the first lead screw 632. The first nut 633 is threaded onto the surface of the first lead screw 632, and a linkage plate is installed between the first nut 633 and the bottom of the roller frame 4 or the side of the movable support 62, and synchronous transmission displacement is achieved through the linkage plate. This provides a technical means to implement the first lead screw transmission structure 63 and improve the automation performance of the overall device.

[0052] The XZ adjustment platform 6 also includes two limiting guide rods 65 respectively installed on the front and rear ends of the bottom of the roller frame 4, and electromagnets 64 respectively installed on the front and rear ends of the top of the positioning support 61. The bottom of the limiting guide rod 65 is snapped through the top structure of the movable support 62. The limiting guide rod 65 can use its snap-fit ​​with the movable support 62 to provide auxiliary support and anti-deviation constraint for the roller frame 4 that is being reciprocated and adjusted. The electromagnet 64 is magnetically connected to a reinforcing plate 20 fixed on the bottom surface of the roller frame 4. Thus, while further improving the stable support of the roller frame 4 for its corresponding transmission roller 3, it will not interfere with the subsequent movement adjustment of the roller frame 4.

[0053] When in use, if it is necessary to adjust the horizontal or vertical movement of the roller frame 4 through the XZ adjustment platform 6, the following steps shall be followed.

[0054] In the vertical direction of the roller frame 4, the first lead screw transmission structure 63 set inside the movable support 62 performs lifting and lowering transmission on the roller frame 4.

[0055] First, turn off the electromagnet 64, which temporarily releases the magnetic attraction to the reinforcing plate 20. Then, start the second brake servo motor 631 in the first lead screw transmission structure 63. The second brake servo motor 631 drives the first lead screw 632 to rotate synchronously through the first reducer 634. Then, the first lead screw 632 engages with the first nut 633, which drives the roller frame 4 and the corresponding transmission roller 3 through its corresponding linkage plate to automatically adjust the height. The limit guide rod 65 engages with the moving support 62 to provide auxiliary support and guidance for the roller frame 4 during the movement. After reaching the designated position;

[0056] In the horizontal direction of the roller frame 4, the first lead screw transmission structure 63 set inside the positioning support 61 performs lifting and lowering transmission on the assembly formed by the roller frame 4 and the movable support 62.

[0057] The second brake servo motor 631 inside the first lead screw transmission structure 63 is started. The second brake servo motor 631 drives the first lead screw 632 to rotate synchronously through the first reducer 634. Then, the first lead screw 632 engages with the first nut 633, so that the first nut 633 drives the roller frame 4, the corresponding transmission roller 3, the movable support 62, and the first lead screw transmission structure 63 set in the movable support 62 to perform automatic horizontal displacement adjustment through its corresponding linkage plate. After completion, the electromagnet 64 is restarted to restore the magnetic attraction and limiting effect of the electromagnet 64 on the roller frame 4, ensuring the stable support effect of the adjusted roller frame 4 on the corresponding transmission roller 3.

[0058] Please see Figure 1 , Figure 7 The offset measuring mechanism includes a first support frame 7 located at the bottom of the conveyor belt 2, and a second support frame 8 is slidably connected to the top rear end of the first support frame 7. Several laser sensing components 9 are arranged on the top of the second support frame 8, all of which are movably sleeved with the bottom side of the conveyor belt 2. A second screw drive structure 10 is drivenly connected to the middle of the second support frame 8. The several laser sensing components 9 can measure the offset distance of the conveyor belt 2 by whether they receive a signal during the linear displacement process of the second support frame 8 driven by the second screw drive structure 10.

[0059] The laser sensing component 9 consists of a laser emitter and a laser receiver, both of which are mounted on the rear end structure at the top of the second support frame 8. The second lead screw transmission structure 10 includes a third brake servo motor 101, a second reducer 102, a second lead screw 103, and a second nut 104. The third brake servo motor 101 and the second reducer 102 are interconnected and are both mounted on the top rear end of the first support frame 7. The inner and outer sides of the second nut 104 are threaded to the surface of the second lead screw 103 and the inner side of the second support frame 8, respectively. One end of the second lead screw 103 is connected to the output end of the second reducer 102. This provides a technical means for the specific implementation of the second lead screw transmission structure 10, improving the automated operation performance of displacement adjustment of the second support frame 8 and multiple laser sensing components 9. The bottom of the second support frame 8 is engaged with a slide rail mounted on the top rear end of the first support frame 7, thereby improving the stability of the second support frame 8 and multiple laser sensing components 9 during reciprocating movement.

[0060] In use, when it is necessary to detect whether the conveyor belt 2 is deviated, the current position of the laser sensing component 9 is taken as the zero point position. The third brake servo motor 101 is started. The third brake servo motor 101 drives the second lead screw 103 to rotate synchronously through the second reducer 102. Then, the second lead screw 103 engages with the second nut 104, so that the second nut 104 drives the second support frame 8 and multiple laser sensing components 9 to move synchronously. During the displacement process, the displacement distance value of each laser sensing component 9 from no signal to receiving a signal is recorded in real time. Subsequently, the conveyor belt 2 is judged to be deviated based on the changes in multiple displacement distance values.

[0061] Please see Figure 1 , Figures 8-10 The detection triggering mechanism includes a curved receiving plate 11 located outside the front and rear ends of the conveyor belt 2. A pressure sensor 15 and a linkage structure are respectively installed on the inner and outer sides of the top of the curved receiving plate 11. After receiving the unloaded material, the linkage structure can synchronously apply pressure to the pressure sensor 15 and trigger the offset measuring mechanism by the pressure change of the pressure sensor 15. The bottom of the curved receiving plate 11 is fixed to the top of the first support frame 7. The linkage structure includes a pressure sensing plate 13, which is movably sleeved inside the curved receiving plate 11. Several T-shaped rods 12 and detection rods 16 are arranged and installed at the bottom of the pressure sensing plate 13, penetrating the curved receiving plate 11. The detection rods 16 are aligned with the pressure sensors 15 installed on the inner wall of the top of the curved receiving plate 11. A return spring 14 is sleeved on one end of the T-shaped rod 12. The two ends of the return spring 14 are respectively fixed to the inner wall of the top of the curved receiving plate 11 and the end surface of one end of the T-shaped rod 12, thereby meeting the real-time detection requirements for unloaded material.

[0062] In use, when the conveyor belt 2 automatically deflects and the material is unloaded onto the top of the curved receiving plate 11, the pressure-sensing plate 13 will apply pressure to the material and, through linkage with the T-shaped rod 12 and the detection rod 16, cause the detection rod 16 to synchronously press and drive the corresponding pressure sensor 15. Then, the pressure sensor 15 changes from a no-pressure data output state to a pressure data output state, which serves as a condition for triggering the offset ranging mechanism to open, thus avoiding the offset ranging mechanism being in a normally open state and reducing the cost of use.

[0063] Please see Figure 10 The pressure-sensitive plate 13 includes three pressure-sensitive plates 131, and the three pressure-sensitive plates 131 divide the space on the top outer side of the curved storage plate 11 from left to right into a left-biased area, a middle area, and a right-biased area. Each of the three pressure-sensitive plates 131 has at least one T-shaped rod 12, a reset spring 14, a pressure sensor 15, and a detection rod 16, and a curved spring sheet 132 is installed between two adjacent pressure-sensitive plates 131.

[0064] In practice, considering that there are many reasons why materials may be ejected from the conveyor belt 2, among which belt deviation is the most likely factor, there are other factors such as vibration and human error. Therefore, taking into account the characteristics of belt deviation ejection, namely that the probability of ejection in the two sides of the conveyor belt 2 is greater than that in the middle, the bearing area of ​​the pressure-sensing plate 13 is further distinguished. When the pressure-sensing plate 131 in the left bias area of ​​the pressure-sensing plate 13 bears pressure and the corresponding pressure sensor 15 outputs pressure data, or when the pressure-sensing plate 131 in the right bias area bears pressure and outputs pressure data, it can be directly used as the trigger condition for the operation of the offset ranging mechanism. If the pressure-sensing plate 131 in the middle area of ​​the pressure-sensing plate 13 bears pressure three times in a row and the pressure sensor 15 associated with it outputs pressure data three times in a short period of time, it can be used as the trigger condition for the operation of the offset ranging mechanism.

[0065] Please see Figures 8-10 Each of the three pressure-sensing plates 131 has several damping pads 21 installed on the top surface of the curved storage plate 11. The damping pads 21, in conjunction with the reset spring 14, dampen and buffer the vibration impact of the pressure sensor 15 beyond the initial pressure, thereby extending the service life of the pressure sensor 15 and reducing the cost of use.

[0066] In use, considering that the reciprocating deformation of the return spring 14 will cause the pressure-sensing plate 13 and the detection rod 16 to reciprocate and impact the pressure sensor 15, which will result in the pressure sensor 15 being impacted even after it initially outputs pressure data, thus reducing its service life, a damping pad 21 is set to work in conjunction with the pressure-sensing plate 13 and the return spring 14. This damping pad does not interfere with the pressure sensor 15 outputting the pressure data from the initial impact of the falling material, but instead provides damping and buffering protection against subsequent vibrations and impacts, thereby extending the service life of the pressure sensor 15.

[0067] Please see Figure 11 A method for using an automated packaging conveyor for roasted gluten production includes the following operating steps:

[0068] S1, Normal material feeding

[0069] The drive roller 3 associated with the power component 5 rotates synchronously, so that the conveyor belt 2 automatically rotates and feeds materials with the support of another drive roller 3 and four roller frames 4, and the feeding direction is divided into upstream and downstream from left to right;

[0070] Furthermore, for the specific conveying and transmission operation of the conveyor belt 2, the power assembly 5 disclosed above can be used to operate the transmission steps of the conveyor belt 2 through the associated transmission roller 3 and roller frame 4;

[0071] S2, Abnormal material release

[0072] During the material conveying process of conveyor belt 2, if either of the two curved receiving plates 11 located at the front and rear ends of conveyor belt 2 receives material, it is determined to be abnormal. When material is received, the linkage structure bears the weight and applies pressure to the pressure sensor 15 synchronously. Subsequently, the offset measuring mechanism is triggered by the pressure change of the pressure sensor 15.

[0073] Furthermore, the specific triggering principle can be achieved through the coordinated operation steps of the curved storage plate 11, pressure-sensing plate 13, T-shaped rod 12, reset spring 14, pressure sensor 15 and detection rod 16 disclosed above.

[0074] S3, Offset Distance Measurement

[0075] After the offset ranging mechanism is triggered, the second lead screw transmission structure 10 drives the second support frame 8 and multiple laser sensing components 9 to automatically move away from the corresponding side of the conveyor belt 2. Simultaneously, the displacement distance value output by the second lead screw transmission structure 10 when each laser sensing component 9 receives a signal is recorded. The change pattern of the multiple displacement distance values ​​is used to determine whether the conveyor belt 2 has deviated.

[0076] Furthermore, the transmission adjustment of the second lead screw drive structure 10 to the second support frame 8 and multiple laser sensing components 9 shall be carried out in accordance with the steps disclosed above. The following will be illustrated by taking the three laser sensing components 9 to detect the left, middle and right sides of the conveyor belt 2 respectively.

[0077] From left to right of conveyor belt 2, the three laser sensing components 9, under the combined transmission of the second screw drive structure 10 and the second support frame 8, successively obtained distance values ​​of upstream D1=6.2, middle D2=9.5, and downstream D3=14.1. The curves drawn from the three sets of data show a clear upward trend, indicating that the edge of conveyor belt 2 gradually shrinks inward, which is equivalent to the conveyor belt 2 as a whole deviating to the right.

[0078] Read the tilt angle data output by the tilt angle sensor 18 on the upstream drive roller 3 of conveyor belt 2. Horizontal direction: tilt angle A1=0.12°, vertical direction B1=0.05°. Read the tilt angle data output by the tilt angle sensor 18 on the downstream drive roller 3 of conveyor belt 2. Horizontal direction: tilt angle A2=0.08°, vertical direction B2=0.03°. Based on the comprehensive comparison, multiple distance values ​​indicate that the downstream end has a larger deviation, indicating that the downstream drive roller 3 is the main problem point. The tilt angle data shows that the right side of the downstream drive roller 3 is slightly higher, but the deviation direction is to the right, which contradicts the "higher deviation, not lower deviation" rule. Therefore, the vertical direction is not the main cause. Thus, it is judged that the downstream drive roller 3 may have a horizontal deviation, that is, the front roller frame 4 of the drive roller 3 is biased to the right, causing the conveyor belt to deviate inward.

[0079] S4, Offset Detection

[0080] The change pattern of multiple displacement distance values ​​is used to determine whether the conveyor belt 2 has shifted. If the multiple displacement distance values ​​are roughly the same, it means that the conveyor belt 2 is still in the specified conveying position. If the multiple displacement distance values ​​show an increasing or decreasing phenomenon, it means that the conveyor belt 2 has shifted.

[0081] Furthermore, after cross-comparing multiple sets of data measured in step S3 above, it was confirmed that conveyor belt 2 was tilted.

[0082] S5, Reset Adjustment

[0083] By readjusting the transmission positions of the two drive rollers 3 and the four roller frames 4 through the four XZ adjustment platforms 6, the conveyor belt 2 is restored to the correct conveying state.

[0084] Further, calculate the adjustment amount;

[0085] Based on comprehensive judgment, the deviation of conveyor belt 2 is likely due to a horizontal skew in the downstream drive roller 3. Therefore, the offset of the roller frame 4 at the front end of the downstream drive roller 3 is first calculated. Using the empirical coefficient method, the required horizontal adjustment is calculated based on the distance value, that is, the maximum distance value minus the minimum distance value, and then 80% of the difference is taken, finally yielding a value of 6.32mm. Subsequently, the roller frame 4 is horizontally displaced to the left by the corresponding XZ adjustment platform 6 through the roller frame 4 by the specified value. The specific transmission principle can be found in the above content.

[0086] Similarly, the front roller frame 4 corresponding to the upstream drive roller 3 needs to be raised to make up for the small height difference. The specific algorithm is to multiply the sine value of 0.05° with the width value of the drive roller 3. At this time, the width value of the drive roller 3 is set to 1200mm, and the final value is about 1nn. Similarly, the drive roller frame 4 is moved vertically upward to the above value using the XZ adjustment platform 6 relative to the roller frame 4.

[0087] S6, Re-inspection Feedback

[0088] Repeat steps S3 and S4 above to check if conveyor belt 2 has been successfully restored. If not, repeat all the above steps until conveyor belt 2 is restored to the correct conveying state. If conveyor belt 2 is successfully restored, then conveyor belt 2 can continue to be used normally.
