[0002] The belt conveyor is mainly composed of two end rollers and a conveyor belt tightly sleeved on the end rollers.

[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0036] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0038] Furthermore, it is required that the present application be understood not only by the actual terms used but also by the meanings connoted by each term.

[0039] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0040] The embodiment of the present application provides a conveyor belt auxiliary deviation adjustment device. Figures 1 to 9 The conveyor belt auxiliary deviation adjustment device 100 provided in the embodiment of the present application includes: a seat body 110, a slider 120 and a distance detector 130.

[0041] The slider 120 is slidably connected to the base 110, and the slider 120 is used to be connected to the conveyor belt 230, so that when the conveyor belt 230 deviates, the deviated conveyor belt 230 drives the slider 120 to slide relative to the base 110 along the deviated direction of the conveyor belt 230. The distance detector 130 is connected to the base 110, and the distance detector 130 faces the slider 120, and the distance detector 130 is used to detect the displacement of the slider 120.

[0042] It should be noted that the distance detector 130 can be any device capable of detecting the displacement of the slider 120. For example, the distance detector 130 can be a laser distance sensor. It should also be noted that the use of a distance detector to detect the displacement of a to-be-detected member is a prior art, and therefore, the principle of using the distance detector 130 to detect the displacement of the slider 120 will not be described in detail here.

[0043] In this way, in the embodiment of the present application, since the slider 120 is connected to the conveyor belt 230, the offset distance of the conveyor belt 230 is equal to the displacement of the slider 120. Then, the offset distance of the conveyor belt 230 can be determined by the distance detector 130 detecting the displacement of the slider 120. Furthermore, the conveyor belt 230 can be adjusted based on the offset distance of the conveyor belt 230. Since the detection accuracy of the distance detector 130 is greater than the accuracy of human eye estimation, the detection accuracy of the offset distance of the conveyor belt 230 can be improved.

[0044] refer to Figure 1 and Figure 6In some embodiments, the conveyor belt auxiliary deviation adjustment device 100 also includes a driver 140. Exemplarily, the driver 140 may be a linear motor, a cylinder or a hydraulic cylinder. Alternatively, the driver 140 may include a driving element such as a rotary motor, a pneumatic motor or a hydraulic motor that can output a rotational driving force, and a transmission mechanism such as a screw nut mechanism or a gear rack mechanism that can convert a rotational motion into a linear motion. The driver 140 is used to drive the deviation adjustment roller 220 that is in rolling contact with the conveyor belt 230 to move. In this way, the tension on both sides of the conveyor belt 230 can be adjusted by driving the deviation adjustment roller 220 to move, so that the tension on both sides of the conveyor belt 230 is substantially equal, thereby solving the problem of "deviation" of the conveyor belt 230.

[0045] In some embodiments, the driver 140 can be controlled by a remote controller, so that the operator can adjust the extension and contraction of the driver 140, thereby facilitating adjustment of the offset of the deviation adjustment roller 220. It should be noted that a driver that can be controlled by a remote controller can be provided in combination with common knowledge in the art, and its working principle is not described in detail here, and reference can be made to the existing principles.

[0046] refer to Figure 1 In some embodiments, the seat body 110 is provided with a slide rail 150. Exemplarily, the extension direction of the slide rail 150 is parallel to the offset direction of the conveyor belt 230. The slider 120 is slidably connected to the slide rail 150. In this way, the slider 120 can slide relative to the seat body 110 by slidingly connecting the slider 120 with the slide rail 150 provided on the seat body 110. Of course, in other embodiments, the seat body 110 can be provided with a slide groove, and the slider 120 can be embedded in the slide groove, so that the slider 120 can slide relative to the seat body 110 under the limiting effect of the slide groove.

[0047] In some embodiments, the conveyor belt auxiliary deviation adjustment device 100 further includes an elastic element 160. For example, the elastic element 160 can be a spring. The elastic element 160 is respectively connected to the slider 120 and the seat body 110, and the elastic element 160 is used to apply a force to the slider 120 so that the slider 120 elastically abuts against the side of the conveyor belt 230.

[0048] It should be noted that the side of the conveyor belt 230 refers to any one of the sides of the conveyor belt 230. It should also be noted that, when the belt conveyor 200 includes a first end roller 240 and a second end roller 250, and the conveyor belt 230 is respectively wound around the first end roller 240 and the second end roller 250, the two sides of the conveyor belt 230 refer to the two sides of the conveyor belt 230 that are opposite to the axial direction of the first end roller 240 (or the second end roller 250). The side of the conveyor belt 230 can be any one of the two sides of the conveyor belt 230. In addition, those skilled in the art can also understand the side of the conveyor belt 230 based on common knowledge in the art.

[0049] refer to Figure 1 and Fig. 9 In some embodiments, a side of the slider 120 that is away from the distance detector 130 is provided with an arc surface 121. The arc surface 121 is convex toward the side away from the distance detector 130, and the arc surface 121 is used to abut against the side of the conveyor belt 230. In this way, during the operation of the conveyor belt 230, the side of the conveyor belt 230 can move relatively smoothly relative to the slider 120.

[0050] The present application embodiment provides a belt conveyor device. Figures 2 to 9 The belt conveyor equipment 10 provided in the embodiment of the present application includes: a belt conveyor 200 and any one of the conveyor belt auxiliary deviation adjustment devices 100 provided in the embodiment of the present application. Exemplarily, the belt conveyor equipment 10 may be a security inspection conveyor equipment.

[0051] In some embodiments, the belt conveyor 200 includes a frame 210, a deflection adjustment roller 220, and a conveyor belt 230. The deflection adjustment roller 220 is rotatably connected to the frame 210, the conveyor belt 230 is wound around the deflection adjustment roller 220, and the seat 110 is connected to the frame 210. The slider 120 abuts against the side of the conveyor belt 230. Therefore, the offset distance of the conveyor belt 230 can be determined by detecting the displacement of the slider 120 by the distance detector 130. Further, the conveyor belt 230 can be deflected based on the offset distance of the conveyor belt 230.

[0052] In some embodiments, the frame 210 is provided with a first support 211 and a second support 212. The two ends of the deflection adjustment roller 220 are rotatably connected to the first support 211 and the second support 212 respectively. The first support 211 can move relative to the frame 210 in a direction perpendicular to the rotation axis of the deflection adjustment roller 220, and the driver 140 of the conveyor belt auxiliary deflection adjustment device 100 is drivingly connected to the first support 211. Figure 6 or Figure 7In this way, the deviation adjustment roller 220 can be deflected by driving the first support 211 to move, thereby adjusting the tension of the side of the conveyor belt 230. Therefore, the problem of "deviation" of the conveyor belt 230 can be solved by making the tension of the two sides of the conveyor belt 230 basically consistent.

[0053] In some embodiments, the belt conveyor 200 further includes a first end roller 240 and a second end roller 250. The first end roller 240 and the second end roller 250 are respectively rotatably connected to the frame 210. The rotating shaft of the first end roller 240, the rotating shaft of the deflection adjustment roller 220, and the rotating shaft of the second end roller 250 are arranged in parallel. The deflection adjustment roller 220 is located between the first end roller 240 and the second end roller 250.

[0054] The conveyor belt 230 is respectively wound around the first end roller 240 and the second end roller 250. The conveyor belt 230 is respectively wrapped around the first end roller 240 and the second end roller 250. Figure 3 The parts of the conveyor belt 230 located between the first end roller 240 and the second end roller 250 are respectively the upper section 231 and the lower section 232. The deflection adjustment roller 220 is located on the side of the lower section 232 away from the upper section 231, and the deflection adjustment roller 220 presses against the lower section 232.

[0055] In some embodiments, there are two deviation adjustment rollers 220 , there are two conveyor belt auxiliary deviation adjustment devices 100 , and the two deviation adjustment rollers 220 are arranged between the first end roller 240 and the second end roller 250 .

[0056] Further, the number of the first supports 211 is two, and the number of the second supports 212 is two. Figure 2 The frame 210 has a first side portion 213 and a second side portion 214 opposite to each other along the rotation axis direction of the first end roller 240. Figure 3 The two first supports 211 are respectively arranged on the first side portion 213 and the second side portion 214; the two second supports 212 are respectively arranged on the first side portion 213 and the second side portion 214. The first supports 211 and the second supports 212 are arranged opposite to each other in a one-to-one correspondence. The second end roller 250 is rotatably connected to a pair of oppositely arranged first supports 211 and second supports 212 in a one-to-one correspondence. The driver 140 is drivingly connected to the first supports 211 in a one-to-one correspondence.

[0057] In this way, the two deviation adjustment rollers 220 can be used to adjust the tension on both sides of the conveyor belt 230 respectively, so that the problem of "deviation" of the conveyor belt 230 can be solved by making the tension on both sides of the conveyor belt 230 basically consistent.

[0058] In some embodiments, the belt conveyor 200 further includes a rotary drive. The rotary drive is drivingly connected to one of the first end roller 240 and the second end roller 250 to drive the first end roller 240 or the second end roller 250 to rotate, thereby driving the conveyor belt 230 to move. Exemplarily, the rotary drive includes a device capable of outputting a rotary driving force, such as a rotary motor, a pneumatic motor, or a hydraulic motor.

[0059] It should be noted that, in some embodiments, the deviation adjustment roller 220 may not be separately provided. Figure 3 , the tension on the right side of the conveyor belt 230 can be increased by driving the right end of the second end roller 250 to move away from the first end roller 240. From this example, it can be seen that in other embodiments, when the belt conveyor 200 is not provided with a dedicated deviation adjustment roller, the first end roller 240 or the second end roller 250 can also be used as a deviation adjustment roller. Therefore, the tension on both sides of the conveyor belt 230 can be basically consistent by adjusting the deviation adjustment roller, so as to solve the problem of "deviation" of the conveyor belt 230.

[0060] In order to help those skilled in the art to better understand the solution provided by the embodiment of the present application, the process of adjusting the deviation of the belt conveyor device 10 is briefly introduced below.

[0061] In some embodiments, when the belt conveyor 200 is in the original state, the conveyor belt 230 is installed at the target position. In other words, the conveyor belt 230 is not offset.

[0062] Furthermore, the conveyor belt auxiliary deviation adjustment device 100 can be installed on the frame 210 of the belt conveyor 200. The side of the slider 120 facing away from the distance detector 130 can be made to abut against the side of the conveyor belt 230. Furthermore, the distance detector 130 can be used to detect the distance between the distance detector 130 and the slider 120. Exemplarily, for example, if the distance between the distance detector 130 and the slider 120 is 150 mm, the current position of the slider 120 can be taken as the "zero point". Furthermore, when the slider 120 is driven by the conveyor belt 230 and moves relative to the distance detector 130, the deviation of the slider 120 relative to the "zero point" can be determined based on the detection result of the distance detector 130.

[0063] Furthermore, the conveyor belt 230 can be moved in a direction opposite to the deviation direction by adjusting the deviation adjustment roller 220. During the adjustment of the deviation adjustment roller 220, the distance between the distance detector 130 and the slider 120 can be monitored in real time until the slider 120 returns to the "zero point".

[0064] Exemplarily, in some embodiments, the driver 140 can be a stepper motor, and the belt conveyor device 10 can include a programmable logic controller (PLC). The distance detector 130 and the stepper motor can be electrically connected to the programmable logic controller. Thus, the programmable logic controller can control the working state of the stepper motor based on the detection result of the distance detector 130 to achieve the effect of automatic deviation adjustment. It should be noted that the use of a programmable logic controller to control the working state of the motor can refer to the prior art, and therefore, the working principle of the programmable logic controller controlling the working state of the stepper motor based on the detection result of the distance detector 130 is no longer described here. In addition, the control technology for controlling the stepper motor can also be purchased directly from the corresponding technical service provider. Of course, in other embodiments, the driver 140 can be controlled by a remote controller, and the operator can adjust the deviation by controlling the remote controller based on the data detected by the distance detector 130.

[0065] refer to Fig.10 In some embodiments, the distance detector 130 includes a first distance detector 130a and a second distance detector 130b. The belt conveyor device 10 includes a programmable logic controller 170. The first distance detector 130a and the second distance detector 130b are respectively connected to the programmable logic controller 170, so that the programmable logic controller 170 can determine whether the conveyor belt 230 is deviated based on the detection results of the first distance detector 130a and the second distance detector 130b. In the case that the conveyor belt 230 is deviated, the offset amount and offset direction of the conveyor belt 230 can be determined.

[0066] Furthermore, the belt conveyor device 10 further includes a first deflection adjustment motor driver 180a and a second deflection adjustment motor driver 180b, wherein the first deflection adjustment motor driver 180a may be a first driving circuit board, and the second deflection adjustment motor driver 180b may be a second driving circuit board.

[0067] The driver 140 includes a first deflection adjustment motor 140a and a second deflection adjustment motor 140b. The first deflection adjustment motor driver 180a and the second deflection adjustment motor driver 180b are respectively connected to the programmable logic controller 170. The first deflection adjustment motor 140a is connected to the first deflection adjustment motor driver 180a, and the second deflection adjustment motor 140b is connected to the second deflection adjustment motor driver 180b.

[0068] For example, the first yaw motor driver 180a and the second yaw motor driver 180b may be connected to a 48V power source, respectively.

[0069] After the belt conveyor 200 is started normally, the belt conveyor device 10 can automatically forward or reverse. When the belt conveyor 200 is working normally, if the conveyor belt 230 is not offset from the center position, the conveyor belt auxiliary deviation adjustment device 100 does not send a control signal, and the first deviation adjustment motor 140a and the second deviation adjustment motor 140b do not operate.

[0070] When the belt conveyor 200 is in forward transmission, the conveyor belt 230 deviates to the left as a whole, and the conveyor belt 230 drives the slider 120 to move to the left as a whole. The first distance detector 130a and the second distance detector 130b can detect that the position of the corresponding slider 120 has changed. The first distance detector 130a and the second distance detector 130b can send the detection data to the programmable logic controller 170 in the form of an electrical signal. The programmable logic controller 170 can send a high-frequency pulse signal to the first deflection adjustment motor driver 180a, so that the first deflection adjustment motor 140a drives the first support 211 on the left to move, so that the left side of the conveyor belt 230 is tightened. At the same time, the programmable logic controller 170 can send a low-frequency pulse signal to the second deflection adjustment motor driver 180b, so that the second deflection adjustment motor 140b drives the first support 211 on the right to move, so that the right side of the conveyor belt 230 is relaxed. Until the data detected by the first distance detector 130a and the second distance detector 130b are basically consistent. Thus, the first deflection adjustment motor 140a and the second deflection adjustment motor 140b are controlled to stop. If the conveyor belt 230 deviates to the right, the working process is opposite to this, which will not be described in detail.

[0071] It should be noted that those skilled in the art may refer to the relevant user manual of the programmable logic controller 170 and use the programmable logic controller 170 to control the first deviation adjustment motor 140 a and the second deviation adjustment motor 140 b .

[0072] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0073] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the embodiments of the present application, and the scope of the embodiments of the present application is defined by the appended claims and their equivalents.
