Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor belt position offset technology, and in particular to a conveyor belt position offset sensor. Background Technology
[0002] With the development of automated production conveyor systems, conveyor belts, as key components in material handling, are widely used in manufacturing, warehousing, packaging, and other fields. During long-term operation, the operational stability of the conveyor belt and the accuracy of material transport directly affect production efficiency and safety. Therefore, effective monitoring and control of the conveyor belt's operating status has become a crucial technological approach to improving system reliability.
[0003] In existing technologies, items moving on conveyor belts are typically detected by installing photoelectric sensors, limit switches, or infrared detectors. These sensors achieve position recognition or edge offset detection through non-contact sensing of the item's surface. Some systems also use cameras combined with image recognition algorithms to determine the item's position. However, because conveyor belts operate in high-frequency, high-cycle conditions, the installation structure of traditional sensing methods is relatively complex, and the sensing accuracy is easily affected by external environmental factors such as dust and light. This limits the timeliness of sensor response and the effectiveness of practical applications.
[0004] However, in existing technologies, when an item shifts in position, the sensor structure is often not combined with a mechanical structure for physical assistance in sensing. A single electronic sensing device has problems such as slow response or inaccurate identification when responding to the item shift, which means that the item shift cannot be identified in a timely and accurate manner during the conveying process. This affects the continuity of the conveying process and the timely processing ability of the operators, and reduces the actual application efficiency of the sensor. Therefore, a conveyor belt position shift sensor is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a conveyor belt position offset sensor, which aims to improve the existing technology where the sensor structure is not combined with a mechanical structure for physical auxiliary sensing, and the single electronic sensing device has the problems of slow response or inaccurate recognition when responding to the offset of the object.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveyor belt position offset sensor, comprising an L-shaped bracket, a sleeve provided on one side of the L-shaped bracket, a positioning plate fixedly connected to one side of the outer wall of the L-shaped bracket, and a contact component installed inside the sleeve;
[0007] The contact assembly includes a slide rod, a circular pressure plate, a mounting base, and a pressure plate sensor. The outer wall of the slide rod is slidably connected to the inside of a sleeve. One side of the outer wall of the circular pressure plate is fixedly connected to one end of the slide rod. A pressure block is fixedly connected to one side of the outer wall of the slide rod. A spring is sleeved on the outer wall of the slide rod. A threaded groove is opened inside the sleeve. A locking ring is threadedly connected inside the sleeve. The outer wall of the mounting base is threadedly connected to the inner wall of the threaded groove. One side of the outer wall of the pressure plate sensor is fixedly connected to the inside of the mounting base. A positioning assembly is installed on the outer wall of the mounting base.
[0008] Furthermore, the positioning assembly includes a connecting cylinder, a sliding block, a rotating plate, and a locking block. One side of the outer wall of the connecting cylinder is fixedly connected to one side of the outer wall of the mounting base. The outer wall of the sliding block is slidably connected to the inner wall of the connecting cylinder. One side of the outer wall of the rotating plate is rotatably connected to one side of the outer wall of the sliding block. The other side of the outer wall of the rotating plate is rotatably connected to one side of the inner wall of the locking block. A sliding rod is fixedly connected to one side of the outer wall of the sliding block.
[0009] Furthermore, a second spring is sleeved on the outer wall of the sliding rod, and a pull ring is provided at one end of the sliding rod.
[0010] Furthermore, one end of the second spring abuts against one side of the outer wall of the sliding block, and the other end of the second spring abuts against one side of the inner wall of the connecting cylinder.
[0011] Furthermore, one side of the outer wall of the card block is rotatably connected to one side of the inner wall of the connecting cylinder, and the outer wall of the card block is engaged with the inner wall of the positioning plate.
[0012] Furthermore, a reinforcing block is fixedly connected to one side of the outer wall of the L-shaped bracket, and mounting bolts are provided inside the L-shaped bracket.
[0013] Furthermore, one end of the spring abuts against one side of the outer wall of the pressure block, and the other end of the spring abuts against one side of the outer wall of the locking ring, and the outer wall of the locking ring is threaded into the inside of the threaded groove.
[0014] Furthermore, the outer wall of the slide rod is slidably connected to the inside of the locking ring, and the other end of the slide rod is located on one side of the tablet pressure sensor.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, by setting L-shaped brackets on both sides of the conveyor belt, the conveyed items come into contact with the circular pressure plate, causing the slide rod to drive the pressure block to squeeze the spring and simultaneously abut against the outside of the pressure plate sensor. At this time, the pressure plate sensor sends a signal to remind the staff that the items have shifted. By setting the slide rod and the circular pressure plate, the sensing range of the sensor is increased, thereby improving the practicality of the sensor.
[0017] 2. In this utility model, pulling the pull ring causes the sliding rod to drive the sliding block to compress the second spring and retract. The movement of the sliding block facilitates the rotation of the rotating plate. The rotation of the rotating plate then facilitates the retraction of the locking block into the connecting cylinder. The height of the sliding connecting cylinder is adjusted inside the L-shaped bracket. After adjusting to the desired position, releasing the pull ring, the reaction force of the second spring, causes the sliding block to push the locking block on the outside of the rotating plate into the positioning plate. This achieves rapid adjustment according to the height of the goods, thereby improving the practicality of the sensor. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-4This utility model provides an embodiment of a conveyor belt position offset sensor, including an L-shaped bracket 17. A sleeve 1 is provided on one side of the L-shaped bracket 17, which is used to accommodate and guide a contact component. A positioning plate 18 is fixedly connected to one side of the outer wall of the L-shaped bracket 17. The positioning plate 18 is used to install and fix the entire sensor structure to the side of the conveyor belt to ensure stability during operation. A contact component is installed inside the sleeve 1. The contact component includes a slide rod 2, a circular pressure plate 3, a mounting base 8, and a pressure plate sensor 9. The outer wall of the slide rod 2 is slidably connected inside the sleeve 1. The slide rod 2 is used to move axially when an item shifts. The movement transmits the sensing action. A circular pressure plate 3 is fixedly connected to one end of a slide rod 2 on one side of its outer wall. When the conveyor belt items shift, the circular pressure plate 3 contacts and pushes the slide rod 2. A pressure block 4 is fixedly connected to one side of the slide rod 2. The pressure block 4 is used to compress the spring 5 during sliding to generate elastic feedback. The spring 5 is sleeved on the outer wall of the slide rod 2, providing the restoring force so that the circular pressure plate 3 can return to its original position after sensing ends. A threaded groove 6 is opened inside the sleeve 1. The threaded groove 6 is used to install an internal locking structure to adjust the preload of the slide rod 2. A locking ring 7 is threaded inside the sleeve 1 to press the mounting base 8 to prevent... To prevent loosening under vibration, the outer wall of the mounting base 8 is threadedly connected to the inner wall of the threaded groove 6. The mounting base 8 supports the tablet pressure sensor 9 and allows its position to be adjusted. One side of the outer wall of the tablet pressure sensor 9 is fixedly connected to the inside of the mounting base 8. The tablet pressure sensor 9 receives trigger signals from the circular tablet 3 and outputs electrical signals for alarm or prompt. A positioning assembly is installed on the outer wall of the mounting base 8. The positioning assembly includes a connecting cylinder 10, a sliding block 12, a rotating plate 14, and a locking block 15. One side of the outer wall of the connecting cylinder 10 is fixedly connected to one side of the outer wall of the mounting base 8. The connecting cylinder 10 guides the sliding block 12, allowing the outer wall of the sliding block 12 to slide. Connected to the inner wall of the connecting cylinder 10, the sliding block 12 can move axially within the connecting cylinder 10 to adjust the state of the locking block 15. One side of the outer wall of the rotating plate 14 is rotatably connected to one side of the outer wall of the sliding block 12. The rotating plate 14 can rotate under the drive of the sliding block 12 to control the opening or closing of the locking block 15. The other side of the outer wall of the rotating plate 14 is rotatably connected to one side of the inner wall of the locking block 15. The locking block 15 is used to cooperate with the positioning structure to achieve quick assembly and disassembly or position fixation. A sliding rod 11 is fixedly connected to one side of the outer wall of the sliding block 12. The sliding rod 11 facilitates the application of force to push the sliding block 12 to slide in the connecting cylinder 10 to adjust the position and locking state of the locking block 15.
[0026] Specifically, through the coordinated operation of the above structures, when an item on the conveyor belt shifts position and touches the circular pressure plate 3, the slide bar 2 slides inward under force. Simultaneously, the pressure block 4 compresses the spring 5, triggering the pressure plate sensor 9 to send a signal, reminding the staff to adjust in time. This achieves accurate perception and response to item shifting. The device has a simple structure and rapid response, enhancing the intelligence and practicality of the conveyor system.
[0027] Reference Figures 1-4 A second spring 13 is fitted on the outer wall of the sliding rod 11 to provide restoring force during sliding, ensuring that the sliding rod 11 can automatically reset. A pull ring 16 is provided at one end of the sliding rod 11 for easy manual pulling to control the sliding mechanism. One end of the second spring 13 abuts against one side of the outer wall of the sliding block 12, serving as a sliding elastic support point to ensure uniform force during sliding. The other end of the second spring 13 abuts against one side of the inner wall of the connecting cylinder 10, providing stable elastic support to prevent the sliding rod 11 from shaking or getting stuck. One side of the outer wall of the locking block 15 is rotatably connected to one side of the inner wall of the connecting cylinder 10 to form a limiting and locking function with the positioning structure, improving the structural stability. The outer wall of the locking block 15 is engaged with the inner wall of the positioning plate 18, achieving position positioning and preventing accidental sliding through the engaging structure. One side of the outer wall of the L-shaped bracket 17 is fixedly connected to... A reinforcing block 19 is used to enhance the rigidity and strength of the support and prevent deformation under stress. The L-shaped support 17 has mounting bolts 20 inside, which are used to achieve stable connection and installation between structural components. One end of the spring 5 abuts against one side of the outer wall of the pressure block 4, which is used to provide rebound force during the pressure block 4 under force, so as to achieve buffer reset. The other end of the spring 5 abuts against one side of the outer wall of the locking ring 7, which is used to provide elastic support for the locking ring 7 and assist in completing the limit locking function. The outer wall of the locking ring 7 is threaded to the inside of the threaded groove 6, which realizes the position fine adjustment and fastening locking through the threaded connection. The outer wall of the slide rod 2 is slidably connected to the inside of the locking ring 7, which is used to guide the sliding in the structure and ensure smooth operation. The other end of the slide rod 2 is set on one side of the pressure sensor 9, which is used to trigger or cooperate with the sensor to realize position detection or status feedback.
[0028] Specifically, the structure achieves controllable sliding and resetting functions through the sliding rod 11 and the cooperating spring 13. The cooperation between the locking block 15 and the positioning plate 18 provides a stable locking effect, enhancing positioning accuracy and safety. The L-shaped bracket 17 ensures the overall strength and connection reliability of the structure through the reinforcing block 19 and the mounting bolts 20. The spring 5 provides elastic support between the pressure block 4 and the locking ring 7, improving the structure's adjustment and limiting capabilities. The cooperation between the sliding rod 2 and the pressure plate sensor 9 enables action feedback or electrical control, providing the structure with intelligent response capabilities. The overall structure is compact, flexible in adjustment, and facilitates stable control and status monitoring.
[0029] Working principle: When the sensor is needed, the L-shaped bracket 17 is installed on the outside of the conveyor belt using the mounting bolt 20. Then, by pulling the pull ring 16, the sliding rod 11 drives the rotating plate 14 on one side of the sliding block 12 to rotate. The rotating plate 14 then drives the locking block 15 to retract into the connecting cylinder 10. By pulling the connecting cylinder 10, it slides inside the L-shaped bracket 17, thereby achieving the effect of adjusting according to the height of the conveyed item / conveyor belt. Then, by releasing the pull ring 16, the reaction force of the second spring 13 causes the locking block 15 on one side of the rotating plate 14 to engage inside the positioning plate 18 for fixation. When the conveyed item or conveyor belt contacts the circular pressure plate 3, the circular pressure plate 3 drives the outer pressure block 4 of the sliding rod 2 to squeeze the first spring 5, thereby achieving the effect of passing through the locking ring 7 and contacting the pressure plate sensor 9. After receiving the pressure, the pressure plate sensor 9 can send a signal to remind the staff of the deviation of the conveyed item.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
