[0048] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] In this application, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0050] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0051] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0052] Furthermore, the terms "first," "second," and the like are primarily used to distinguish between different devices, elements, or components, which may or may not have the same specific type and configuration, and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0053] As mentioned in the background art, in the related art, the deviation of the conveyor belt is completely observed and debugged by human eyes during the debugging process. However, the accuracy of visual observation is low, and it is difficult to accurately determine the specific value of the deviation.

[0054] In order to solve the above problems, an embodiment of the present application provides a conveyor belt detection device, wherein a first contact member and a second contact member are respectively used to abut against the two sides of the conveyor belt to be detected in a first direction, so that the displacement of the first contact member or the second contact member is accurately sensed through the sensing component, and the offset of the conveyor belt to be detected can be accurately measured, thereby greatly improving the detection accuracy.

[0055] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0056] See also Figures 1 to 3 , this embodiment provides a conveyor belt detection device 1, which includes: a frame 100, a first contact assembly 200 and a sensor assembly 300; the first contact assembly 200 includes a first contact piece 210 and a second contact piece 220, and the first contact piece 210 and the second contact piece 220 are movably arranged on the frame 100 along a first direction, and the first contact piece 210 and the second contact piece 220 are respectively used to abut against the two sides of the conveyor belt 2 to be detected in the first direction; the sensor assembly 300 is arranged on the movement trajectory of the first contact piece 210 and the second contact piece 220, when the conveyor belt 2 to be detected deviates in the first direction, the sensor assembly 300 is used to sense the displacement of the first contact piece 210 or the second contact piece 220 in the first direction; the transmission direction of the conveyor belt 2 to be detected is parallel to the length direction of the conveyor belt 2 to be detected, and the first direction is parallel to the width direction of the conveyor belt 2 to be detected.

[0057] The first direction is Figure 3 The direction indicated by the arrow X.

[0058] When inspecting the conveyor belt 2 to be inspected, the frame 100 of the conveyor belt detection device 1 is fixed in a suitable position to ensure that the first contact member 210 and the second contact member 220 are respectively used to abut against the two sides of the conveyor belt 2 to be inspected in the first direction, and drive the conveyor belt 2 to be inspected to move. If the conveyor belt 2 to be inspected has not deviated, the first contact member 210 and the second contact member 220 are respectively lightly abutted against the two sides of the conveyor belt 2 to be inspected. At this time, the sensor component 300 will not sense the displacement of the first contact member 210 or the second contact member 220 in the first direction. If the conveyor belt 2 to be inspected deviates in the first direction, the conveyor belt 2 to be inspected will push the first contact member 210 or the second contact member 220 to displace relative to the frame 100 in the first direction. For example, if the conveyor belt 2 to be inspected deviates to one side, it will squeeze the contact member on that side, causing it to deviate in the first direction. The first contact member 210 or the second contact member 220 is displaced in the first direction, and the sensor component 300 senses the displacement change and converts the displacement change into an offset. For example, the displacement information is transmitted to a related control system or display device so that the staff can clearly understand the offset of the conveyor belt 2 to be detected and adjust the conveyor belt 2 to be detected according to the offset. Compared with the naked eye observation method in the related art, the present embodiment accurately senses the displacement of the first contact member 210 or the second contact member 220 through the sensor component 300, and can accurately measure the offset of the conveyor belt 2 to be detected, thereby greatly improving the detection accuracy and being able to monitor the running status of the conveyor belt 2 to be detected in real time. Once an offset occurs, it can be detected in time so that the operator can quickly take adjustment measures to avoid equipment damage or production quality problems due to the long-term deviation of the conveyor belt 2 to be detected.

[0059] In one possible embodiment, see Figure 3 and Figure 4 The conveyor belt detection device 1 also includes a movable mounting member 110 movably mounted on the frame 100 along a first direction, and a first contact member 210 and a second contact member 220 are arranged on the movable mounting member 110; the sensing assembly 300 includes a first sensor 310 and a second sensor 320. Along the first direction, the movable mounting member 110 is arranged between the first sensor 310 and the second sensor 320. When the conveyor belt 2 to be detected is skewed toward the first contact member 210 in the first direction, the first contact member 210 drives the movable mounting member 110 to move toward the first sensor 310, so that the first sensor 310 senses the displacement of the movable mounting member 110. When the conveyor belt 2 to be detected is skewed toward the second contact member 220 in the first direction, the second contact member 220 drives the movable mounting member 110 to move toward the second sensor 320, so that the second sensor 320 senses the displacement of the movable mounting member 110.

[0060] Therefore, if the conveyor belt 2 to be detected is skewed in the first direction toward the first contact member 210, the conveyor belt 2 to be detected will squeeze the first contact member 210, so that the first contact member 210 drives the movable mounting member 110 to move toward the first sensor 310. When the movable mounting member 110 moves to a certain position, the first sensor 310 senses and detects the displacement of the movable mounting member 110. Similarly, if the conveyor belt 2 to be detected is skewed in the first direction toward the second contact member 220, the second contact member 220 drives the movable mounting member 110 toward the second sensor 320. The second sensor 320 senses and detects the displacement of the movable mounting member 110, so that the specific direction and amount of the deviation of the conveyor belt 2 to be detected can be accurately detected through the cooperation of the movable mounting member 110 with the first sensor 310 and the second sensor 320. Moreover, once the conveyor belt 2 to be detected is skewed, the movable mounting member 110 can quickly drive the contact member to move, so that the first sensor 310 or the second sensor 320 can quickly sense the displacement change, thereby achieving rapid response and taking adjustment measures in time to reduce the adverse effects caused by the skew.

[0061] Of course, the above structure is not a limitation to the conveyor belt detection device 1 in this embodiment. For example, the first contact member 210 and the second contact member 220 can be directly slidably disposed on the frame 100 .

[0062] In one possible embodiment, see Figure 3 and Figure 4 The first sensor 310 and the second sensor 320 are both external spring self-resetting displacement sensors. The external spring self-resetting displacement sensors include a sensor body, a spring and a measuring rod. One end of the spring is connected to the sensor body and the other end is connected to the measuring rod. When the first contact member 210 moves in the first direction toward the first sensor 310, the movable mounting member 110 pushes the measuring rod of the first sensor 310. When the second contact member 220 moves in the first direction toward the second sensor 320, the movable mounting member 110 pushes the measuring rod of the second sensor 320.

[0063] Therefore, when the conveyor belt 2 to be detected is operating normally and has not deviated, the movable mounting part 110 is in the middle position. At this time, the measuring rods of the two external spring self-resetting displacement sensors are also in the initial position, the springs are in a natural state, and the sensors do not detect obvious displacement. When the conveyor belt 2 to be detected is skewed in the first direction toward the first contact member 210, the conveyor belt 2 to be detected will squeeze the first contact member 210, and the first contact member 210 drives the movable mounting part 110 to move toward the first sensor 310. The movable mounting part 110 gradually approaches and pushes the measuring rod of the first sensor 310, causing the measuring rod to compress the spring and produce displacement. Similarly, when the conveyor belt 2 to be detected is skewed in the first direction toward the second contact member 220, the second contact member 220 drives the movable mounting part 110 to move toward the second sensor 320, and the movable mounting part 110 pushes the measuring rod of the second sensor 320, so that The measuring rod and the spring generate corresponding displacements. The sensor body changes through the displacement of the measuring rod and can convert the displacement signal into an electrical signal and transmit it to the control system or display device. The combination of the spring and the measuring rod makes the sensor very sensitive to tiny displacement changes and can accurately detect tiny offsets of the conveyor belt 2 to be detected, which helps to timely discover and correct the early offset of the conveyor belt 2 to be detected, and avoid further expansion of the offset to affect the production quality and equipment operation stability. Moreover, the high sensitivity and stability of the sensor ensure the accuracy and reliability of the test results, and provide precise data support for subsequent adjustments and controls. In addition, the self-resetting characteristics of the spring enable the measuring rod to automatically return to its initial position after the offset of the conveyor belt 2 to be detected is eliminated, and it is ready for the next test at any time, which can realize continuous and uninterrupted monitoring of the conveyor belt 2 to be detected without manual intervention and reset, greatly improving the efficiency and reliability of the detection.

[0064] Of course, the first sensor 310 and the second sensor 320 are not limited to the above-mentioned sensors. For example, the first sensor 310 and the second sensor 320 can also be inductive displacement sensors, which measure displacement by sensing the change in distance between a metal target (a metal sheet can be installed on the movable mounting part 110) and the sensor head. When the movable mounting part 110 moves due to the offset of the conveyor belt 2 to be detected, the distance between the metal sheet and the sensor head of the inductive displacement sensor changes, and the sensor senses the displacement; or a photoelectric displacement sensor, in which the light emitted by the light emitter is irradiated onto the reflective surface on the movable mounting part 110, and the receiver receives the reflected light. When the movable mounting part 110 moves, the angle or intensity of the reflected light changes, and the receiver detects the displacement based on the change in light.

[0065] For example, see Figure 4 Along the first direction, both ends of the movable mounting member 110 are respectively provided with abutting portions 1101 , and the two abutting portions 1101 are respectively used to abut the connecting rods of the first sensor 310 and the second sensor 320 .

[0066] In one possible embodiment, see Figure 4 and Figure 5 The first contact member 210 includes a first connecting member 2101 and a first contact head 2102 detachably arranged on the connecting member, the first contact head 2102 extends toward the conveyor belt 2 to be detected, the second contact member 220 includes a second connecting member 2201 and a second contact head 2202 arranged on the second connecting member 2201, the second contact head 2202 extends toward the conveyor belt 2 to be detected, the first contact head 2102 and the second contact head 2202 cooperate to clamp the two sides of the conveyor belt 2 to be detected in the first direction, and the second direction is perpendicular to the plane of detecting the conveyor belt 2 to be detected.

[0067] It is worth noting that the first contact head 2102 and the second contact head 2202 can be composed of cylindrical roller wheels, which are installed on the connecting parts through bearings, or they can be sliders of rectangular or other shapes, with smooth surfaces. The part that contacts the side of the conveyor belt 2 to be detected can be made of wear-resistant materials, etc., which are not limited here.

[0068] Since the first contact head 2102 and the second contact head 2202 extend toward the conveyor belt 2 to be detected, they can stably clamp the two sides of the conveyor belt 2 to be detected in the first direction, ensuring that when the conveyor belt 2 to be detected is offset, the contact head can promptly and accurately sense the offset force and transmit the force to the movable mounting member 110 through the connecting member, thereby improving the accuracy and reliability of the detection. In addition, the first contact head 2102 can be detachably arranged on the first connecting member 2101, which is convenient for replacement when the contact head is worn or damaged, thereby reducing maintenance costs. At the same time, it is also possible to replace the appropriate contact head according to the different types and specifications of the conveyor belt 2 to be detected, thereby improving the versatility of the detection device. In addition, by adjusting the relative positions of the first contact head 2102 and the second contact head 2202 in the first direction, it is possible to adapt to the detection requirements of conveyor belts 2 to be detected of different widths.

[0069] In one possible embodiment, see Figure 3The first connecting member 2101 is provided with a plurality of first adjustment holes 21011, and the first adjustment holes 21011 are used to install the first contact head 2102. The plurality of first adjustment holes 21011 are arranged at intervals along the extension direction of the first connecting member 2101; the second connecting member 2201 is provided with a plurality of second adjustment holes 22011, and the plurality of second adjustment holes 22011 are arranged at intervals along the extension direction of the second connecting member 2201, and the second adjustment holes 22011 are used to install the second contact head 2202. The plurality of second adjustment holes 22011 correspond one-to-one to the plurality of first adjustment holes 21011 along the first direction, and along the second direction, the spacing between the one-to-one corresponding first adjustment holes 21011 and the second adjustment holes 22011 in the first direction decreases to adapt to conveyor belts 2 to be detected with different widths, and the second direction is parallel to the length direction of the conveyor belt 2 to be detected.

[0070] Among them, the second direction is Figure 3 The direction indicated by arrow Y.

[0071] By providing a plurality of first adjustment holes 21011 on the first connecting member 2101 for mounting the first contact head 2102, and similarly providing a plurality of second adjustment holes 22011 on the second connecting member 2201 for mounting the second contact head 2202, the plurality of first adjustment holes 21011 correspond one-to-one with the plurality of second adjustment holes 22011 along the first direction, and along the second direction, the spacing between the one-to-one corresponding first adjustment holes 21011 and the second adjustment holes 22011 in the first direction decreases gradually, so that when it is necessary to adapt to different widths of the conveyor belt 2 to be detected, a suitable combination of the first adjustment holes 21011 and the second adjustment holes 22011 can be selected for installation according to the actual width of the conveyor belt 2 to be detected. For example, for a wider conveyor belt 2 to be detected, a pair of first adjustment holes 21011 and second adjustment holes 22011 with a larger spacing can be selected. 011; For a narrower conveyor belt 2 to be detected, a pair with a smaller spacing is selected. During the detection process, this adjustable structure can quickly adapt to conveyor belts 2 to be detected of different widths without replacing the entire conveyor belt detection device 1, thereby improving the flexibility and versatility of the detection. By selecting appropriate adjustment holes to install the first contact head 2102 and the second contact head 2202, it can be ensured that the first contact head 2102 and the second contact head 2202 can be tightly clamped on both sides of the conveyor belt 2 to be detected, thereby improving the stability and accuracy of the detection, so that the conveyor belt detection device 1 can be applicable to conveyor belts 2 to be detected of various widths, meeting the needs of different production scenarios, and can be adjusted according to actual conditions whether in a small production line or a large-scale automated production system, thereby improving the adaptability and practicality of the conveyor belt detection device 1.

[0072] In one possible embodiment, see Figure 3One end of the first connecting member 2101 is rotatably connected to the movable mounting member 110, and a first contact head 2102 is provided on the other end, and the rotation axis of the first connecting member 2101 is parallel to the second direction; one end of the second connecting member 2201 is rotatably connected to the movable mounting member 110, and a second contact head 2202 is provided on the other end, and the rotation axis of the second connecting member 2201 is parallel to the second direction; the locking structure 400, the locking structure 400 is used to lock the first connecting member 2101 and the second connecting member 2201 to the movable mounting member 110, or unlock them from the movable mounting member 110.

[0073] By making one end of the first connecting member 2101 and the second connecting member 2201 rotatably connected to the movable mounting member 110 respectively, and the rotation axis is parallel to the second direction, the first connecting member 2101 and the second connecting member 2201 can be rotated around the axis, thereby adjusting the position and angle of the first contact head 2102 and the second contact head 2202, and the locking structure 400 can lock the first connecting member 2101 and the second connecting member 2201 on the movable mounting member 110 to ensure that their positions are stable during the detection process. When it is necessary to adjust the distance between the first contact head 2102 and the second contact head 2202, the connecting member can be unlocked by the locking structure 400 and the corresponding operation can be performed, so that the first contact head 2102 and the second contact head 2202 can be adjusted by rotating the connecting member. The contact positions of the first contact head 2102 and the second contact head 2202 with both sides of the conveyor belt 2 to be detected ensure that the offset of the conveyor belt 2 to be detected can be accurately detected. This flexibility can adapt to conveyor belts 2 to be detected of different specifications and shapes, thereby improving the versatility of the detection device. By flexibly adjusting the distance between the first contact head 2102 and the second contact head 2202, it can be ensured that the contact heads are in closer and more accurate contact with both sides of the conveyor belt 2 to be detected, thereby improving the detection accuracy of the detection device for the offset of the conveyor belt 2 to be detected. The design of the rotating connection and locking structure 400 enables the detection device to adapt to conveyor belts 2 to be detected of different types and specifications, as well as different working environments and operating conditions, thereby improving the adaptability and reliability of the conveyor belt detection device 1.

[0074] In one possible embodiment, see Figure 3The locking structure 400 includes a first locking structure 410 and a second locking structure 420. The first locking structure 410 includes a first adjusting portion 4101, a first locking hole 4102 and a first fastener. The first adjusting portion 4101 is arranged on the end portion of one end connected to the frame 100. A first arc-shaped groove 41011 is opened on the first adjusting portion 4101. The center of the first arc-shaped groove 41011 is located on the rotation axis of the first connecting member 2101. The locking hole is provided on the frame 100 and corresponds to the first arc-shaped groove 41011. The first fastener is used to pass through the first arc-shaped groove 41011 and extend into the first locking hole 4102 to lock the first connecting member 2101 to the movable mounting member 110; the second locking The stopping structure 420 includes a second adjustment portion 4201, a second locking hole 4202 and a second fastener. The second adjustment portion 4201 is arranged on the end portion of one end where the second connecting member 2201 is connected to the frame 100. A second arc-shaped groove 42011 is opened on the second adjustment portion 4201. The center of the second arc-shaped groove 42011 is located on the rotation axis of the second connecting member 2201. The second locking hole 4202 is arranged on the frame 100 and corresponds to the second arc-shaped groove 42011. The second fastener is used to pass through the second arc-shaped groove 42011 and extend into the second locking hole 4202 when the second connecting member 2201 is adjusted to the second preset angle, so as to lock the second connecting member 2201 to the movable mounting member 110.

[0075] The fasteners may be any fasteners such as bolts, screws, etc., which are not limited here.

[0076] When it is necessary to adjust the distance between the first contact head 2102 and the second contact head 2202, rotate the first connecting member 2101 and the second connecting member 2201, and adjust the angles of the first contact head 2102 and the second contact head 2202 so that the first contact head 2102 and the second contact head 2202 can be well abutted against the two sides of the conveyor belt 2 to be detected. During the adjustment process, the first arc groove 41011 on the first adjustment part 4101 and the second arc groove 42011 on the second adjustment part 4201 allow the first connecting member 2101 and the second connecting member 2201 to rotate within a certain range to find the best contact position. After adjusting to a suitable angle, use the first fastener to pass through the first arc groove 41011 and extend into the first locking hole 4102 to lock the first connecting member 2101 to the movable mounting member 110; at the same time, use the second fastener to pass through the second arc groove 4201 1 and extends into the second locking hole 4202 to lock the second connecting member 2201 to the movable mounting member 110, wherein the fastener can be a bolt, a screw, etc., and by tightening the fastener, the connecting member is tightly connected to the frame 100 to achieve the locking function. When it is necessary to adjust again, first loosen the first fastener and the second fastener to withdraw them from the locking hole. After loosening the fastener, the first connecting member 2101 and the second connecting member 2201 can rotate freely. At this time, the angle of the first contact member 210 and the second connecting member 2201 can be adjusted again as needed. In this embodiment, the use of the first fastener and the second fastener makes the locking and unlocking process simple and fast. The operator can complete the locking and unlocking operations of the connecting member in a short time, which is convenient for adjusting, maintaining or replacing the contact head of the conveyor belt detection device 1, reducing the downtime of the conveyor belt detection device 1 and improving production efficiency.

[0077] Of course, the locking structure 400 is not limited to the above structure. For example, the locking structure 400 can also be a cam locking structure 400. A locking block is installed at each end of the first connecting member 2101 and the second connecting member 2201 connected to the frame 100, and a rotatable cam handle is installed at the corresponding position of the frame 100. The cam is connected to the cam handle. When locking is required, the cam handle is rotated to press the cam on the locking block. The cam handle is rotated in the opposite direction, and the cam gradually releases the pressure on the locking block. Under the action of the reset spring, the cam handle quickly returns to the initial position to achieve unlocking.

[0078] In one possible embodiment, see Figures 5 to 9 The conveyor belt detection device 1 also includes a second contact assembly 500, which includes a third connecting member 510, a third contact head 520 and a fourth contact head 530 arranged on the movable mounting member 110, and the third contact head 520 and the fourth contact head 530 are arranged on the third connecting member 510.

[0079] Since the third contact head 520 and the fourth contact head 530 are arranged on the third connecting member 510, and the third connecting member 510 is arranged on the movable mounting member 110, the second contact assembly 500 can be applicable to the conveyor belt 2 to be detected of smaller size, thereby improving the conveyor belt detection device 1 during the detection process. When the conveyor belt 2 to be detected deviates during operation, the third contact head 520 and the fourth contact head 530 will be subjected to the lateral force of the conveyor belt 2 to be detected. According to the direction and degree of the deviation, the third contact head 520 and the fourth contact head 530 will transmit the force to the movable mounting member 110 through the third connecting member 510, thereby triggering the sensor assembly 300 of the detection device to detect the deviation of the conveyor belt 2 to be detected.

[0080] For example, the first contact assembly 200 is suitable for a conveyor belt 2 to be detected with a width of 20 mm to 940 mm, and the second contact assembly 500 is suitable for a conveyor belt 2 to be detected with a width of 10 mm to 60 mm.

[0081] In one possible embodiment, see Figure 8 The third connecting member 510 is provided with an adjustment slot 5101 , which extends along the first direction. The third contact head 520 and the fourth contact head 530 are movably installed in the adjustment slot 5101 .

[0082] By opening an adjustment groove 5101 extending along the first direction on the third connecting member 510, and movably installing the third contact head 520 and the fourth contact head 530 in the adjustment groove 5101, the distance between the third contact head 520 and the fourth contact head 530 can be adjusted to adapt to conveyor belts 2 to be detected with different widths. In addition, during the detection process, the positions of the third contact head 520 and the fourth contact head 530 in the adjustment groove 5101 can be adjusted according to the actual operating conditions and offset characteristics of the conveyor belt 2 to be detected to find the optimal contact point and improve the accuracy of the detection.

[0083] In one possible embodiment, see Figure 10 and Figure 11 The conveyor belt detection device 1 also includes a control module 600, which includes: a control cabinet 610 and a control component 620. The control cabinet 610 is used to drive the conveyor belt 2 to be detected to move along the conveying direction; the control component 620 is electrically connected to the control cabinet 610 and to the sensor component 300. When the sensor component 300 does not detect the deviation of the conveyor belt 2 to be detected within the preset detection time, the control component 620 is used to control the control cabinet 610 to close.

[0084] Among them, the preset detection time is set according to actual conditions and is not limited here.

[0085] Therefore, when the conveyor belt 2 to be detected is in normal working condition, the sensor component 300 continues to detect the position of the conveyor belt 2 to be detected. If the sensor component 300 does not detect the deviation of the conveyor belt 2 to be detected within the preset detection time, it means that the conveyor belt 2 to be detected is running stably and there is no abnormality. In this case, the control component 620 will control the control cabinet 610 to shut down, which can avoid unnecessary energy waste. At the same time, it can also reduce the operating time of the conveyor belt detection device 1, extend the service life of the conveyor belt detection device 1, and reduce the wear and heat generation of the conveyor belt detection device 1, thereby improving the operating efficiency of the conveyor belt detection device 1. In addition, the control module 600 realizes the automatic control of the conveyor belt 2 system to be detected. Without manual intervention, the system can automatically determine whether the control cabinet 610 needs to be shut down based on the signal of the sensor component 300, thereby improving the degree of automation and reliability of production.

[0086] In addition, the control module 600 in this embodiment can directly provide a control electrical cabinet 610 for the conveyor belt 2 to be tested. When the components of the conveyor belt 2 to be tested are assembled, the power is turned on so that the conveyor belt 2 to be tested can be put into operation during the assembly. There is no need to debug after the whole machine is assembled and powered on, which avoids waiting for too long and debugging difficulties caused by equipment space problems after the whole machine is assembled.
