Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] See Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of a slip detection device provided in an embodiment of this application. Figure 2 This is a partial schematic diagram of a slip detection device provided in an embodiment of this application. Figure 3 This is a schematic diagram illustrating the interaction between a slip detection device and a conveyor belt according to an embodiment of this application. The slip detection device according to an embodiment of this application includes a support arm 100, a mating wheel 200, a marking part 300, and a detection element 400. The support arm 100 has a first end 110 and a second end 120 disposed opposite each other in its extending direction. The first end 110 is mounted on a mounting surface 510. The mating wheel 200 is rotatably connected to the second end 120 and is used to abut against the conveyor belt 520, rotating under the drive of the conveyor belt 520. The marking part 300 is disposed on the mating wheel 200. The detection element 400 is mounted on the support arm 100 and is used to detect the frequency of occurrence of the marking part 300.

[0033] Specifically, by providing a mating wheel 200 at the second end 120 of the support arm 100 that abuts against the conveyor belt 520, the conveyor belt 520 can drive the mating wheel 200 to rotate during rotation. The frequency of the marking portion 300 on the mating wheel 200 can be detected by the detection element 400 to detect the rotational speed of the conveyor belt 520, thereby determining the slippage of the conveyor belt 520. The first end 110 and the second end 120, which connect to the mounting surface 510, are positioned opposite each other in the extending direction of the support arm 100, allowing the support arm 100 to connect to the mounting surface 510 located anywhere below the conveyor belt 520. This makes the installation position of the slippage detection device unrestricted, improving its ease of installation and adaptability. In this application, the conveyor belt 520 can be a belt.

[0034] See Figure 1 and Figure 2 In one embodiment, the support arm 100 is provided with a mating groove 145, and the detection element 400 is at least partially accommodated in the mating groove 145 and located on the side of the mating wheel 200 near the first end 110.

[0035] Specifically, when the slip detection device is located below the conveyor belt 520, the detection element 400 is located below the mating wheel 200. The detection element 400 is at least partially accommodated in the mating groove 145, thereby protecting the detection element 400 and reducing the size of the slip detection device, thus miniaturizing the slip detection device.

[0036] See Figure 1 and Figure 2 In one embodiment, the mating wheel 200 has a mounting groove 210 on its surface, and the marking part 300 is mounted in the mounting groove 210. This allows the detection element 400 and the mating wheel 200 to be positioned opposite each other in the extending direction of the support arm 100, reducing the radial dimension of the support arm 100 and further miniaturizing the slippage detection device. In other embodiments, the marking part 300 may also be provided on the side wall of the mating wheel 200.

[0037] Furthermore, the groove wall of the mounting groove 210 has threads, and the marking part 300 is threadedly connected to the groove wall of the mounting groove 210, thereby improving the stability of the marking part 300 installed in the mounting groove 210, and at the same time improving the convenience of installing and removing the marking part 300 relative to the mounting groove 210.

[0038] Furthermore, the mating wheel 200 has multiple spaced grooves 220 on its surface, which increases the friction between the mating wheel 200 and the conveyor belt 520, allowing the mating wheel 200 to rotate stably under the drive of the conveyor belt 520, thereby improving the accuracy of the slippage detection device's detection results.

[0039] In one embodiment, the detection element 400 is a proximity switch, the marking part 300 is made of metal, and the mating wheel 200 is made of non-metallic material. Thus, as the marking part 300 rotates synchronously with the mating wheel 200, the detection element 400 can detect the frequency of the marking part 300's appearance. Preferably, the marking part 300 is a metal rivet.

[0040] See Figure 1 and Figure 2 In one embodiment, the support arm 100 includes a base 130, a support seat 140, and an elastic member 150. A first end 110 is located on the base 130, and a second end 120 is located on the support seat 140. One end of the elastic member 150 is connected to the support seat 140, and the other end of the elastic member 150 is connected to the base 130. The elastic member 150 is used to apply a pushing force that moves the base 130 and the support seat 140 away from each other.

[0041] Specifically, the base 130 is used to connect with the mounting surface 510 below the conveyor belt 520. The mating wheel 200 is mounted on the end of the support 140 away from the base 130. An elastic element 150 applies a reciprocating thrust to the base 130 and the support 140, allowing the mating wheel 200 to press firmly against the conveyor belt 520, thus ensuring stable rotation under the drive of the conveyor belt 520 and improving the accuracy of the slippage detection device's results. Preferably, the elastic element 150 is a spring.

[0042] See Figure 1 and Figure 2 In one embodiment, the base 130 and the support 140 are slidably connected, and one of the base 130 and the support 140 is provided with a limiting block 141, and the other of the base 130 and the support 140 is provided with a limiting wall 131. The limiting wall 131 is used to abut against the limiting block 141 to limit the base 130 and the support 140 from moving away from each other.

[0043] Specifically, the base 130 and the support 140 are slidably connected, allowing them to stably move away from each other under the force of the elastic element 150, thus ensuring that the mating wheel 200 abuts against the conveyor belt 520. Furthermore, the limiting block 141 and the limiting wall 131 ensure that when the base 130 and the support 140 are moved to their extreme positions, the limiting wall 131 abuts against the limiting block 141, preventing the base 130 or the support 140 from separating and improving the reliability of the slippage detection device.

[0044] See Figure 1 and Figure 2In one embodiment, one of the base 130 and the support 140 is provided with a receiving groove 133. The groove wall of the receiving groove 133 is provided with an elongated hole 132 communicating with the outside. The side of the hole wall of the elongated hole 132 near the mating wheel 200 is configured as a limiting wall 131. The other of the base 130 and the support 140 is inserted into the receiving groove 133 and is provided with a limiting block 141. The limiting block 141 is used to be inserted into the elongated hole 132.

[0045] Specifically, the base 130 or the support 140 is inserted into the receiving groove 133 to achieve a sliding connection between the base 130 and the support 140. The limiting block 141 is inserted into the elongated hole 132, allowing for a direct observation of the position between the support 140 and the base 130 to determine if they are properly installed, thus improving the reliability of the slippage detection device.

[0046] See Figure 1 and Figure 2 In one embodiment, the elongated hole 132 extends along the extension direction of the support arm 100, and the limiting block 141 is slidably connected to the hole wall of the elongated hole 132, thereby limiting the limiting block 141 so that the base 130 and the support seat 140 can only slide relative to each other along the extension direction of the support arm 100, thereby restricting the rotation of the support seat 140 relative to the base 130. This ensures that the axis of the mating wheel 200 is perpendicular to the transmission direction of the conveyor belt 520, so that the mating wheel 200 rotates stably under the drive of the conveyor belt 520, and the slippage of the conveyor belt 520 can be accurately measured by the rotation speed of the mating wheel 200.

[0047] See Figure 1 and Figure 2 In one embodiment, the elastic element 150 is housed in the receiving groove 133, thereby protecting the elastic element 150 and limiting the elastic element 150 to stably extend and retract along the extension direction of the support arm 100.

[0048] See Figure 1 and Figure 2 In one embodiment, the receiving groove 133 is disposed on the base 130, and the support base 140 includes a fixing plate 142 and two support pieces 143. The two support pieces 143 are connected to the side of the fixing plate 142 away from the second end 120 and are spaced apart. The two support pieces 143 are at least partially accommodated in the receiving groove 133, and the limiting block 141 is disposed on the side of the support pieces 143 that are far apart from each other.

[0049] Specifically, since the two support plates 143 are spaced apart, and the side of each support plate 143 near the second end 120 is connected to the fixing plate 142, while the side of each support plate 143 near the first end 110 is not restricted, the side of each support plate 143 near the first end 110 can undergo elastic deformation to move closer together. This facilitates the insertion of the limiting block 141 on the support plate 143 into the receiving groove 133 as the support plate 143 deforms, so as to cooperate with the elongated hole 132, thus improving the ease of installation and disassembly of the slip detection device. One end of the elastic element 150 abuts against the bottom wall of the receiving groove 133, and the other end abuts against the fixing plate 142.

[0050] Furthermore, each of the two support plates 143 has a limiting block 141 on its opposite side, and the limiting block 141 is located on the side of the support plate 143 closer to the first end 110.

[0051] See Figure 1 and Figure 2 In one embodiment, the fixing plate 142 has a mounting hole, which is configured as a groove of a mating groove 145. The area between the two support plates 143 is configured as a mating groove 145. The detection element 400 passes through the mounting hole, and part of the detection element 400 is located between the two support plates 143.

[0052] Furthermore, the slippage detection device also includes two fixing rings 146, both of which are threadedly connected to the detection piece 400 and respectively abut against both sides of the fixing plate 142 to stably fix the detection piece 400 on the fixing plate 142.

[0053] See Figure 1 and Figure 2 In one embodiment, the support base 140 further includes two ear plates 144, both of which are connected to the side of the fixing plate 142 away from the fixing plate 142 and are spaced apart. A rotating shaft 147 is provided between the two ear plates 144, and a mating wheel 200 is located between the two ear plates 144 and is rotatably connected to the rotating shaft 147.

[0054] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the base 130 includes a fixing part 134 and an adjusting part 135. A first end 110 is located on the fixing part 134. One end of the adjusting part 135 is connected to an elastic member 150, and the other end is threadedly connected to the fixing part 134. The adjusting part 135 is configured to rotate relative to the fixing part 134 to adjust the length of the base 130 in the extension direction of the support arm 100.

[0055] Specifically, the receiving groove 133 is provided in the adjusting part 135, and the adjusting part 135 is threadedly connected to the fixing part 134, so that the length of the base 130 in the extension direction of the support arm 100 can be changed, thereby adjusting the height of the support arm 100 to adapt to different mounting surfaces 510 below the conveyor belt 520, thus improving the adaptability of the slip detection device.

[0056] Furthermore, the adjustment part 135 includes a first rod segment 136 and a second rod segment 137. The radial dimension of the second rod segment 137 is larger than the radial dimension of the first rod segment 136. The receiving groove 133 is disposed in the second rod segment 137. The first rod segment 136 is threadedly connected to the fixing part 134, thereby reducing the volume of the adjustment part 135 and realizing the lightweighting of the slip detection device.

[0057] Furthermore, the fixing part 134 also includes a support plate 138 and an adjusting rod 139 connected to each other. The adjusting rod 139 is threaded onto the support plate 138, which is used to connect with the mounting surface 510. The radial dimension of the support plate 138 is larger than that of the adjusting rod 139, thereby increasing the contact area between the fixing part 134 and the mounting surface 510 and improving the installation stability.

[0058] The support plate 138 has multiple spaced fixing holes, which can be connected to the mounting surface 510 by screws or other fasteners, thereby improving the installation stability of the slippage detection device. It should be noted that the orientation of the mating wheel 200 can be determined first, and then the support plate 138 can be fixed to the mounting surface 510, thus ensuring that the axis of the mating wheel 200 is perpendicular to the transmission direction of the conveyor belt 520.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
