Description

Technical Field

[0001] This invention relates to the field of cover rubber thickness detection technology, specifically to a conveyor belt cover rubber thickness detection device. Background Technology

[0002] The thickness of the conveyor belt cover rubber is a key factor determining its service life, operational performance, and cost. Too thin a cover rubber can lead to premature wear and damage to the core, and even belt breakage; too thick a cover rubber will increase the conveyor belt's weight and energy consumption, causing unnecessary waste. Therefore, developing an advanced conveyor belt cover rubber thickness detection device that meets the needs of industrial production has significant practical importance and application value.

[0003] Current conveyor belt cover rubber thickness testing devices on the market have many unresolved issues. Most devices have fixed detection component positions, making it difficult to flexibly adjust the detection angle and position according to conveyor belts of different widths and operating states. This results in a limited detection range, making it impossible to achieve comprehensive multi-directional detection, easily leading to blind spots and affecting the integrity of the detection results. In terms of detection, the installation and fixing methods are cumbersome, with poor adaptability, making it difficult to quickly adapt to different detection scenarios. Furthermore, the angle and position adjustment of the detection components are not flexible enough, failing to effectively complement other detection components, further affecting the accuracy of the detection data and making it difficult to meet the needs of industrial production for conveyor belt cover rubber thickness detection. Summary of the Invention

[0011] Preferably, the lifting assembly includes a lead screw rotatably mounted inside the adjusting groove and a bevel gear fixedly mounted on the lead screw, the movable seat is screwed onto the lead screw, and the mounting plate is provided with a cleaning mechanism for wiping the surfaces of the multiple auxiliary rangefinders.

[0012] Preferably, a drive motor is installed on one side of the fixed seat, and a second bevel gear that meshes with a first bevel gear is rotatably installed inside the adjusting groove. The main shaft of the drive motor passes through the fixed seat and is fixed to one side of the second bevel gear.

[0013] Preferably, the detection component includes a mounting frame fixedly installed on the top of the base and multiple mounting seats installed on one side of the mounting frame. Each of the multiple mounting seats is equipped with a laser rangefinder and a detection sensor on the side near the conveyor belt body. The laser rangefinder is located above the detection sensor. The mounting frame is provided with a moving component for moving the multiple mounting seats.

[0014] Preferably, the movable component includes an upper slide rail fixedly installed on the top of the mounting frame and a lower slide rail installed on one side of the mounting frame. A plurality of support rods are fixedly installed between the mounting frame and the lower slide rail. The plurality of support rods are used to fix the lower slide rail. A plurality of mounting slides are slidably installed on both the lower slide rail and the upper slide rail. The plurality of mounting slides correspond one-to-one with a plurality of mounting seats. One end of two mounting slides is connected to a mounting seat.

[0015] Preferably, the auxiliary component includes a stabilizing seat fixedly installed on the top of the base and an arc-shaped plate fixedly installed on the top of the stabilizing seat. Two bonding plates are installed on the arc-shaped plate, the bottom of the conveyor belt body is bonded to the two bonding plates, and a guide component for guiding the conveyor belt body is provided on the top of the arc-shaped plate.

[0016] Preferably, the guide assembly includes a lower roller rotatably mounted on the arc plate, two support rods fixedly mounted on the top of the arc plate, and an upper roller rotatably mounted between the two support rods.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] This invention, through the inclusion of an auxiliary detection mechanism, enables rapid installation and fixation, adapting to various detection scenarios. A drive motor engages bevel gear two with bevel gear one, causing the lead screw to rotate and thus moving the movable seat. Combined with the synergistic effect of the electric push rod and the hinged seat, the angle and position of the mounting plate and auxiliary rangefinder can be flexibly adjusted, ensuring multi-directional and precise auxiliary detection of the conveyor belt cover rubber thickness. This complements the laser rangefinder and detection sensor in the detection components, improving the reliability of the detection results and enhancing the comprehensiveness and accuracy of conveyor belt cover rubber thickness detection. Furthermore, the overall structure is easy to operate, ensuring the reliability and efficiency of conveyor belt cover rubber thickness detection.

[0020] This invention, through the design of a cleaning mechanism, allows a push plate to move a cleaning pad at one end stably, enabling targeted wiping of the surfaces of multiple auxiliary rangefinders on one side of the mounting plate. This structure allows cleaning without disassembling the auxiliary rangefinders, making it convenient to operate and not affecting the continuity of the testing process. It effectively removes dust, impurities, and other stains that may adhere to the surface of the auxiliary rangefinders, preventing stains from obstructing or interfering with the ranging signal, ensuring that the auxiliary rangefinders maintain an accurate testing state at all times, and preventing deviations in testing data caused by dirt on the equipment surface. This, in turn, ensures the accuracy of the auxiliary testing mechanism's auxiliary testing results for the thickness of the conveyor belt cover rubber. At the same time, the cleaning pad can be directly removed and replaced, thereby increasing the cleaning effect on the auxiliary rangefinders and facilitating their long-term use.

[0031] 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.

[0032] Please refer to Figure 1 and Figure 2A conveyor belt cover rubber thickness detection device includes: a base 1, a plurality of support plates 2 fixedly installed on the top of the base 1, wherein a rotating roller 8 is rotatably installed between two support plates 2, a conveyor belt body 3 is wound around the two rotating rollers 8, a detection component is provided on the top of the base 1, and an auxiliary component is also provided on the top of the base 1.

[0033] Please refer to Figure 7 and Figure 8 An auxiliary testing mechanism is located on one side of one of the support plates 2 and is used to assist in the testing of the thickness of the conveyor belt cover rubber. The auxiliary testing mechanism includes multiple fixing slots 21 formed on one side of one of the support plates 2 and a connecting plate 5 installed on one side of one of the support plates 2. One end of the connecting plate 5 is inserted into the interior of one of the fixing slots 21. A fixing seat 22 is fixedly installed on one side of the connecting plate 5. A mounting plate 6 is provided on the top of the fixing seat 22. Multiple auxiliary rangefinders 28 are installed on one side of the mounting plate 6. The top of the connecting plate 5 is provided with a device for measuring the thickness of the conveyor belt cover rubber. The adjustment assembly for adjusting the mounting plate 6 includes an adjustment groove on the top of the connecting plate 5, a movable seat 31 slidably installed inside the adjustment groove, and an adjustment seat 27 movably installed on the top of the connecting plate 5. One end of the adjustment seat 27 is fixed to the mounting plate 6. A stabilizing component for adjusting and stabilizing the mounting plate 6 is provided on one side of the movable seat 31. The stabilizing component includes a hinge seat 29 fixedly installed on one side of the movable seat 31 and the bottom of the adjustment seat 27, and an electric push rod 30 installed between the two hinge seats 29. A lifting component for lifting the movable seat 31 is provided inside the adjustment groove.

[0034] First, place the base 1 stably in the working area, ensuring that the multiple support plates 2 fixedly installed on its top are in a vertical and stable state. Then, wrap the conveyor belt body 3 around the two rotating rollers 8, ensuring that the conveyor belt body 3 can rotate smoothly with the rotating rollers 8. Next, align one end of the connecting plate 5 of the auxiliary detection mechanism with any one of the multiple fixing slots 21 opened on one side of one of the support plates 2, insert and fix it, so that the connecting plate 5 is stably fixed on the support plate 2. At this time, the fixing seat 22 fixedly installed on one side of the connecting plate 5 and the mounting plate 6 on the top of the fixing seat 22 are also positioned accordingly. The multiple auxiliary rangefinders 28 on one side of the mounting plate 6 can be initially used for auxiliary detection of the thickness of the conveyor belt cover rubber. When it is necessary to adjust the position of the auxiliary rangefinders 28... When adapted to different testing needs, the adjustment component on the top of the operating plate 5 can be used to push the movable seat 31 to slide in the adjustment groove, or the movement state of the adjustment seat 27 can be directly adjusted to drive the mounting plate 6 and the auxiliary rangefinder 28 to initially change their position and angle. To ensure that the mounting plate 6 and the auxiliary rangefinder 28 are stable and accurate after adjustment, the electric push rod 30 is activated. Its extension and retraction will drive the movable seat 31 and the adjustment seat 27 to move in coordination through the two hinge seats 29, further fine-tuning the angle and position of the mounting plate 6. At the same time, the lifting component inside the adjustment groove can lift the movable seat 31 to help achieve accurate positioning of the mounting plate 6 and the auxiliary rangefinder 28 and ensure the accuracy of the auxiliary testing.

[0035] Furthermore, such as Figure 7 and Figure 8 As shown, the lifting assembly includes a lead screw 24 rotatably mounted inside the adjusting groove and a bevel gear 25 fixedly mounted on the lead screw 24. A movable seat 31 is screwed onto the lead screw 24. A cleaning mechanism for wiping the surfaces of multiple auxiliary rangefinders 28 is provided on the mounting plate 6. A drive motor is mounted on one side of the fixed seat 22. A bevel gear 26, which meshes with the bevel gear 25, is rotatably mounted inside the adjusting groove. The main shaft of the drive motor passes through the fixed seat 22 and is fixed to one side of the bevel gear 26. Based on this, the drive motor main shaft first passes through the fixed seat 22, driving the bevel gear 26 fixed thereto to rotate. The movement is caused by the meshing of bevel gear 26 with bevel gear 25, which is rotatably mounted in the adjustment groove. Bevel gear 25 rotates with bevel gear 26 and drives screw 24 to rotate stably in the adjustment groove. When screw 24 rotates, it converts the rotational motion into the linear lifting motion of moving seat 31 along the adjustment groove. After moving seat 31 is lifted, it drives adjusting seat 27 and mounting plate 6 fixed to adjusting seat 27 to lift synchronously through hinge seat 29 on one side and electric push rod 30. This adjusts the height of auxiliary rangefinder 28 on mounting plate 6. Once the height is adjusted to a suitable height for detecting the thickness of conveyor belt cover rubber, the drive motor can be turned off.

[0036] Furthermore, such as Figure 4 and Figure 5As shown, the detection assembly includes a mounting frame 7 fixedly mounted on the top of the base 1 and multiple mounting seats 14 mounted on one side of the mounting frame 7. Each mounting seat 14 has a laser rangefinder 15 and a detection sensor 16 mounted on the side near the conveyor belt body 3. The laser rangefinder 15 is located above the detection sensor 16. The mounting frame 7 is equipped with a moving assembly for moving the multiple mounting seats 14. The moving assembly includes an upper slide rail 11 fixedly mounted on the top of the mounting frame 7 and a lower slide rail 13 mounted on one side of the mounting frame 7. Multiple support rods 17 are fixedly mounted between the mounting frame 7 and the lower slide rail 13, and the support rods 17 are used to fix the lower slide rail 13. Multiple mounting blocks 12 are slidably mounted on both the lower slide rail 13 and the upper slide rail 11. Each mounting block 12 corresponds one-to-one with a mounting seat 14, and one end of each mounting block 12 is connected to a mounting seat 14. First, confirm that the mounting bracket 7 fixedly installed on the top of the base 1 is in a stable state. Then, assemble multiple mounting seats 14 on one side of the mounting bracket 7, and install a laser rangefinder 15 and a detection sensor 16 on the side of each mounting seat 14 near the conveyor belt body 3. Ensure that the laser rangefinder 15 is above the detection sensor 16 and that the two are aligned. When the detection position needs to be adjusted, push the mounting seat 14 so that it drives the corresponding mounting slide 12 to slide smoothly along the upper slide rail 11 and the lower slide rail 13 until the laser rangefinder 15 and the detection sensor 16 move to the target position that matches the thickness detection of the cover rubber of the conveyor belt body 3. Finally, fix the position of the mounting slide 12, and the laser rangefinder 15 and the detection sensor 16 can be started for detection. Moreover, the multiple bearing rods 17 can stably support the lower slide rail 13 to ensure the stability of the lower slide rail 13 during use.

[0037] Furthermore, such as Figure 3 and Figure 6As shown, the auxiliary assembly includes a stabilizing seat 9 fixedly installed on the top of the base 1 and an arc-shaped plate 4 fixedly installed on the top of the stabilizing seat 9. Two bonding plates 20 are installed on the arc-shaped plate 4. The bottom of the conveyor belt body 3 is bonded to the two bonding plates 20. A guide assembly for guiding the conveyor belt body 3 is provided on the top of the arc-shaped plate 4. The guide assembly includes a lower roller 18 rotatably installed on the arc-shaped plate 4, two support rods 19 fixedly installed on the top of the arc-shaped plate 4, and an upper roller 10 rotatably installed between the two support rods 19. The upper roller 10 and the lower roller 18 are both located between the two bonding plates 20. One end of the conveyor belt body 3 passes through the space between the upper roller 10 and the lower roller 18. Based on this, the auxiliary assembly is first... The stabilizing seat 9, fixedly installed on the top of the base 1, is adjusted to a horizontal and stable state, ensuring that the position of the arc plate 4 fixed on its top is accurate. Then, the two bonding plates 20 on the arc plate 4 are installed in place, ensuring that the bottom of the conveyor belt body 3 can be tightly bonded to the two bonding plates 20, thereby providing stable support for the conveyor belt body 3 and preventing it from affecting the detection accuracy due to shaking during the detection process. Then, one end of the conveyor belt body 3 is slowly passed through the gap between the upper roller 10 and the lower roller 18, so that the conveyor belt body 3 can maintain a stable conveying trajectory during operation through the guiding action of the upper roller 10 and the lower roller 18. With the support of the bonding plates 20, it provides stable conveying for the subsequent detection components to accurately detect the thickness of the conveyor belt cover rubber.

[0038] Please also refer to... Figure 9 The cleaning mechanism includes guide grooves 32 at the top and bottom of the mounting plate 6 and a push plate 23 mounted on one side of the mounting plate 6. A removable cleaning pad 33 is mounted on one end of the push plate 23, and the end of the cleaning pad 33 relative to the push plate 23 contacts the surface of the auxiliary rangefinder 28. Auxiliary slide blocks 34 are slidably mounted inside both guide grooves 32, and one end of each auxiliary slide block 34 passes through the guide groove 32 and is fixed to the push plate 23. Based on this, the push plate 23 is first connected to the two auxiliary slide blocks 34, so that one end of each auxiliary slide block 34 passes through the corresponding guide groove 32 and is firmly fixed to the push plate 23. At this time, the end of the cleaning pad 33 relative to the push plate 23 needs to be aligned with the surface of the mounting plate 6. The auxiliary rangefinder 28 is in close contact with the surface of the auxiliary rangefinder 28. When dust, impurities, or other contaminants affecting the detection accuracy adhere to the surface of the auxiliary rangefinder 28, manually push the push plate 23. The push plate 23 will drive the auxiliary slide 34 to slide smoothly along the guide groove 32. At the same time, the cleaning pad 33 will wipe the surface of the auxiliary rangefinder 28. After the contaminants on the surface of the auxiliary rangefinder 28 are cleaned, push the push plate 23 to reset. If the cleaning pad 33 becomes worn or heavily soiled after a period of use, it can be removed from the push plate 23 for replacement or cleaning. After replacement, reinstall it to ensure the cleaning effect of the auxiliary rangefinder 28 and ensure that the auxiliary rangefinder 28 always maintains a good detection condition.
