Description

Technical Field

[0001] This utility model mainly relates to the field of conveying device technology, specifically to a conveyor belt width adjustment structure. Background Technology

[0002] In industrial scenarios such as logistics sorting, food processing, and electronic component conveying, conveyor belts are core equipment for continuous material transfer, and their width adaptability directly affects production efficiency and material conveying stability. Traditional conveyor belts mostly adopt a fixed width design. When materials of different sizes need to be conveyed, the entire conveyor belt assembly needs to be replaced, which not only increases equipment procurement costs but also requires downtime for disassembly and reassembly, leading to production interruptions and making it difficult to meet the needs of flexible production.

[0003] With the improvement of industrial automation, production lines are placing higher demands on the dynamic adjustment capabilities of conveyor belts. Automation of width adjustment is required to reduce manual intervention and adapt to the rapid production changeover needs of the production line. Furthermore, the adjustment process must maintain synchronization and stability to avoid equipment wear or material damage caused by imbalance in the movement of the conveyor components. Currently, some adjustable-width conveyor belts use single-rail support for the conveyor components, which are prone to tilting due to uneven force during movement, causing the synchronous belt to deviate. Moreover, they lack effective position detection mechanisms, relying solely on manual visual judgment of the adjustment endpoint, which easily leads to over-adjustment, causing collisions and deformation of the conveyor profiles, further reducing equipment lifespan, and failing to meet the high-efficiency, precise, and safe conveying requirements of modern production lines.

[0020] See attached document Figure 1-4 A conveyor belt width adjustment structure includes a first conveyor component and a second conveyor component arranged in parallel, extending symmetrically along the material conveying direction to form a conveying plane for carrying materials. The first conveyor component is fixedly equipped with a drive mechanism to provide power for the operation of the conveyor belt; the second conveyor component is correspondingly equipped with a width adjustment mechanism to drive the second conveyor component to move relative to the first conveyor component to adjust the width; a sliding support mechanism is also bolted to the lower end of the second conveyor component to provide guidance and support for its movement; a position detection component is fixedly mounted on a bracket at the end of the second conveyor component away from the width adjustment mechanism to monitor its movement position in real time and achieve safety limiting.

[0021] The width adjustment mechanism includes an adjustment motor 1 fixed to the side of the second conveying assembly via a motor mounting base, and an adjustment screw 2 arranged horizontally perpendicular to the conveying direction. The output shaft end of the adjustment motor 1 and one end of the adjustment screw 2 are both fixedly fitted with synchronous pulleys A3 via a key connection. A synchronous belt is wound between the two synchronous pulleys A3 to form a belt drive structure, so that the torque of the adjustment motor 1 can be transmitted to the adjustment screw 2 through the synchronous pulleys A3 and the synchronous belt, driving the adjustment screw 2 to rotate around its own axis.

[0022] The drive mechanism includes a drive motor 4 fixed to the bottom of the first conveying assembly by a motor bracket, and a transmission shaft 5 extending horizontally along the conveying direction. The output shaft end of the drive motor 4 and one end of the transmission shaft 5 are both fitted with synchronous pulleys B6 by a flat key. A synchronous belt is wound between the two synchronous pulleys B6 to form a belt drive structure, so that the power of the drive motor 4 can be transmitted to the transmission shaft 5 through the synchronous pulleys B6 and the synchronous belt, driving the transmission shaft 5 to rotate.

[0023] The sliding support mechanism includes linear slide rails A7 and B8, which are parallel to each other at both ends of the second conveying component along a direction perpendicular to the conveying direction. The lower ends of linear slide rails A7 and B8 are fixed to the equipment base by expansion bolts. The upper ends of linear slide rails A7 and B8 are slidably fitted with moving blocks 9. Moving blocks 9 can move smoothly along the length of the slide rails, and the upper end of moving blocks 9 is fixedly connected to the bottom of the second conveying component by bolts, so that the second conveying component can move synchronously with moving blocks 9. At the same time, the double slide rail support ensures stability during the movement and avoids tilting or jamming.

[0024] Both the first and second conveying components include a conveying profile 10, a plurality of pulleys A11 rotatably disposed inside the conveying profile 10, and a pulley B12 rotatably disposed at the lower end of the conveying profile 10. The surfaces of pulleys A11 and B12 are provided with synchronous belt grooves, and a conveying synchronous belt is wound between them to form a closed conveying loop. When pulley A11 or pulley B12 rotates, it can drive the conveying synchronous belt to circulate and convey materials.

[0025] The pulley B12 is positioned at the lower end of the conveying profile 10 via a positioning seat 13. The positioning seat 13 is fixedly connected to the outer wall of the conveying profile 10 by bolts and has a bearing embedded inside. The axle of the pulley B12 is rotatably connected to the positioning seat 13 via the bearing, enabling the pulley B12 to rotate flexibly. The pulleys A11 and B12 are connected by a conveying synchronous belt, and the pulleys A11, B12, and the conveying synchronous belt are all located inside the conveying profile 10. Multiple pulleys A11 are limited by multiple spaced limiting strips on the side wall of the profile to prevent the conveying synchronous belt from deviating during operation.

[0026] The lower end of the conveying profile 10 in the second conveying assembly is threadedly connected to the adjusting screw 2 via an external linkage plate. The upper end of the linkage plate is welded and fixed to the conveying profile 10, and the lower end has an internal threaded hole through which the adjusting screw 2 passes and forms a threaded fit. When the adjusting screw 2 rotates, the linkage plate can move along the screw axis, thereby driving the second conveying assembly to move synchronously. The two ends of the second conveying assembly are fixedly connected to the moving block 9 by bolts, so that the moving block 9 slides along the linear slide rail A7 and the linear slide rail B8, providing guidance for the movement of the second conveying assembly and ensuring that it always remains parallel to the first conveying assembly.

[0027] Both ends of the drive shaft 5 pass through the positioning seat 13 and are interference-fitted with the inner ring of the bearing in the positioning seat 13, so that the drive shaft 5 can rotate stably relative to the positioning seat 13. Two pulleys B12 are respectively connected and sleeved on both ends of the drive shaft 5 by flat keys. The flat keys are embedded between the keyway of the drive shaft 5 and the hub keyway of the pulleys B12 to achieve circumferential fixation, ensuring that the drive shaft 5 can synchronously drive the two pulleys B12 to rotate when rotating, so as to drive the synchronous belts of the first and second conveying components to run synchronously and ensure the consistency of material conveying.

[0028] The width adjustment mechanism also includes a bearing seat 14 and an adjusting screw mounting seat 15 for supporting the adjusting screw 2, and two belt tension bearings 16 for tensioning the synchronous belt between the synchronous pulleys A3. The bearing seat 14 and the adjusting screw mounting seat 15 are fixed on the equipment base, and bearings are embedded inside them. The two ends of the adjusting screw 2 pass through the inner rings of the bearings in the adjusting screw mounting seat 15 to achieve stable rotation of the adjusting screw 2. The two belt tension bearings 16 are fixed on the bearing seat 14 and set between the two synchronous pulleys A3, and are distributed at intervals with the synchronous pulleys A3. Their wheel surfaces abut against the inner side of the synchronous belt. By adjusting the position of the belt tension bearings 16, the tension of the synchronous belt can be changed to avoid slippage during transmission.

[0029] The position detection component includes a sliding strip 17 fixed to the equipment base along the length of the linear slide rail, and origin photoelectric sensor 18, limit photoelectric sensor A19, and limit photoelectric sensor B20 spaced apart on one side of the sliding strip 17. It also includes a sensing plate 21 that moves synchronously with the moving block 9. The origin photoelectric sensor 18 is located between the limit photoelectric sensor A19 and the limit photoelectric sensor B20. All three are fixed to the sliding strip 17 by a bracket, and their detection ends face the moving block 9. The sensing plate 21 is fixed to the side of the moving block 9 near the sliding strip 17 by bolts. When the moving block 9 moves, it can pass through the detection areas of the origin photoelectric sensor 18, the limit photoelectric sensor A19, and the limit photoelectric sensor B20 in sequence. The origin photoelectric sensor 18 is used to detect the position of the second conveying component. The limit photoelectric sensor A19 and the limit photoelectric sensor B20 correspond to the maximum and minimum width limit positions of the conveyor belt, respectively. When the sensing plate 21 triggers the limit photoelectric sensor, it can send a signal to the control system to stop the operation of the regulating motor 1 and prevent overtravel damage to the equipment.

[0030] The lower end of the first conveying component is provided with a support plate A22 and a support plate B23 fixedly connected thereto. The support plates A22 and B23 are distributed at intervals along the conveying direction. Their upper ends are fixedly connected to the bottom of the conveying profile 10 of the first conveying component by bolts, and their lower ends are welded and fixed to the equipment base to form a stable support structure, ensuring that the first conveying component remains fixed during operation.

[0031] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
