Abstract
Description
Technical Field
[0001] This invention relates to the field of transfer, specifically to a roller conveyor sample transfer device for raw materials and fuels. Background Technology
[0002] The transfer device can transport raw materials and fuel test samples contained in sealed containers, connecting sampling, sample preparation and testing stations in series, replacing manual transfer, and realizing sealed and efficient transfer of samples. The device uses rollers as the main conveyor and consists of a frame, drive motor, transmission mechanism, sample container, positioning sensor and control system. The container is placed on the roller conveyor, and the motor drives the roller to rotate through the chain or gear. The container moves smoothly by relying on friction, which can realize linear conveying and positioning. The overall structure is reliable, the load is stable and the maintenance is simple.
[0003] Existing roller conveyor sample transfer devices typically require setting the roller speed to a low level to ensure that the material container does not shake or tip over during transport. This low-speed operation maintains the stability of the material container, but it results in a long sample transport cycle, slow flow rate, and low overall transfer efficiency. If the roller speed is increased to improve efficiency, the material container is easily affected by inertia and vibration during start-up, stopping, and operation, leading to deviation, shaking, or even tipping over. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a roller conveyor sample transfer device for raw materials and fuels, which solves the problem that existing devices can only ensure the stability of the material bucket by reducing the roller speed, resulting in long conveying cycles and low transfer efficiency.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a roller conveyor sample transfer device for raw materials and fuels, comprising a roller conveyor base and a plurality of rollers, and further comprising: The slide is fixed relative to the roller conveyor seat. The two sets of slides are set at an angle, and sliding plates are slidably installed in both sets of slides.
[0006] The rotating wheels are mounted on the sliding plate, and a buffer belt for supporting the material bucket is installed between the two rotating wheels.
[0007] The toothed synchronous belt is installed at the end of the slide rail via a synchronous pulley, and the outer circumferential surface of the toothed synchronous belt is provided with several protrusions.
[0008] In the initial state, the buffer strip is at the beginning of the slide. When the buffer strip and the sliding plate slide along the slide to the end, the sliding plate abuts against the protrusion.
[0009] Preferably, the two sets of slides are symmetrically arranged, and each set of slides is fixedly connected to a support block.
[0010] Preferably, the contact surface between the sliding plate and the slide rail is set as a rough surface.
[0011] Preferably, the outer circumferential surface of the rotating wheel is provided with a plurality of annular grooves, and the two ends of the buffer belt are wound and fixed in the relatively hard annular grooves.
[0012] Preferably, each of the sliding plates is fixedly installed with a plurality of fasteners, and a coil spring is fixedly installed between the inner ring of the fastener and the outer circumferential surface of the rotating wheel. When the coil spring is in a stationary state, the buffer belt is in a taut state.
[0013] Preferably, the slide rail has a groove inside that is adapted to the sliding plate, and the length of the groove is equal to the length of the slide rail.
[0014] Preferably, the synchronous pulley is rotatably connected to the slide rail and driven to rotate by an external power source. The two synchronous belts are connected by a toothed synchronous belt drive, the toothed synchronous belt is in a taut state, and the two synchronous belts are symmetrically arranged.
[0015] Preferably, a support wheel is rotatably installed between the two sets of slides, and the support wheel abuts against its corresponding synchronous belt.
[0016] Preferably, the protrusions are distributed at equal intervals on the toothed synchronous belt.
[0017] Preferably, the buffer strip forms a "V" shape when squeezed by the material barrel.
[0018] Compared with the prior art, the present invention has the following advantages: By setting an inclined slide and using a buffer belt to support the material bucket, unlike the traditional roller conveyor device which requires constant control of roller rotation and continuous energy consumption, this device does not need to control roller rotation. It can achieve automatic transfer by relying solely on the inclined slide and the weight of the material bucket itself, resulting in lower energy consumption and lower operating costs. The buffer belt is squeezed by the material bucket to form a V-shaped support, which can automatically center and wrap and limit the material bucket, preventing it from shaking, shifting, or tipping over. It can also maintain stability even at high speeds. Through the cooperation of the inclined slide, sliding plate, and toothed synchronous belt with protrusions, gravity-driven transfer and flexible buffer deceleration are achieved, solving the problems of low efficiency at low speeds and easy material tipping at high speeds in traditional devices.

[0021] like Figures 1-10 As shown, a roller conveyor sample transfer device for raw materials and fuels includes a roller conveyor base 1 and a plurality of rollers 2, the rollers 2 being rotatably mounted on the roller conveyor base 1, and further includes: The slide 3 is fixed relative to the roller seat 1. Two sets of slide 3 are inclined. Sliding plates 4 are slidably installed in both sets of slide 3. There are several sets of sliding plates 4. The two sets of slide 3 are symmetrically arranged, and a support block is fixedly connected between the two sets of slide 3. The slider near the roller seat 1 is fixedly connected to the roller seat 1 to improve the stability of the two sets of slide 3. The contact surface between the sliding plate 4 and the slide 3 is set as a rough surface to increase the friction between them. When the sliding plate 4 is installed in the slide 3, the friction keeps the sliding plate 4 stable. When the material bucket slides along the slide 3 by its own weight, it will overcome the friction between the sliding plate 4 and the slide 3, and thus the sliding plate 4 and the buffer belt 6 will slide together. The slide 3 has a groove inside that matches the sliding plate 4. The length of the groove is equal to the length of the slide 3, so that the sliding plate 4 can be installed inside the slide 3 through the groove. The sliding plate 4 can also slide out from the end of the slide 3.
[0022] A rotating wheel 5 is rotatably mounted on a sliding plate 4. A buffer belt 6 for supporting the material bucket containing raw materials is installed between two rotating wheels 5. The outer circumferential surface of the rotating wheel 5 is provided with several annular grooves 9. The two ends of the buffer belt 6 are wrapped and fixed in the relatively rigid annular grooves 9. The annular grooves 9 on the outer circumference of the rotating wheel 5 are provided to position and fix the buffer belt 6, which can prevent the buffer belt 6 from axially moving or loosening during the stretching and resetting process. Several fixing parts 10 are fixedly installed on each sliding plate 4. A coil spring 11 is fixedly installed between the inner ring of the fixing part 10 and the outer circumferential surface of the rotating wheel 5. When the coil spring 11 is in a stationary state, the buffer belt 6 is in a taut state. Through the cooperation of the fixing part 10 and the coil spring 11, the buffer belt 6 can automatically tighten and reset when it is not under the pressure of the material bucket, realizing the automatic tensioning and recycling of the buffer belt 6, avoiding slack and sagging, and ensuring continuous and stable support for the material bucket. A toothed synchronous belt 7 is installed at the end of the slide rail 3 via a synchronous pulley 8. Several protrusions 13 are provided on the outer circumference of the toothed synchronous belt 7. The synchronous pulley 8 is rotatably connected to the slide rail 3 and driven to rotate by an external power source, such as a servo motor. The two synchronous belts are connected via the toothed synchronous belt 7, which is in a taut state. The two synchronous belts are symmetrically arranged. Support wheels 12 are rotatably installed between the two sets of slide rails 3, and each support wheel 12 abuts against its corresponding synchronous belt. When the toothed synchronous belt 7 is under force, it can compress the support wheel 12, preventing the toothed synchronous belt 7 from collapsing inward under force, thus improving the stability of the protrusions 13. Several protrusions 13 are evenly distributed on the toothed synchronous belt 7, ensuring uniform and consistent force distribution on the buffer limit position of the sliding plate 4, facilitating the control of the material barrel's deceleration and stopping. When the buffer belt 6 is compressed by the material barrel, it forms a "V" shape. The U-shaped structure can automatically center and support the material bucket, effectively suppressing bucket shaking, deviation and tipping, and further improving the stability during conveying.
[0023] In the initial state, the buffer strip 6 is at the beginning of the slide 3. When the buffer strip 6 and the sliding plate 4 slide along the slide 3 to the end, the sliding plate 4 abuts against the protrusion 13.
[0024] By setting an inclined slide 3, a sliding plate 4, a buffer belt 6, and a toothed synchronous belt 7 with protrusions 13 on one side of the roller conveyor, the material barrel's own weight can be used to drive the buffer belt 6 and the sliding plate 4 to slide along the slide 3 during the material barrel conveying process. The protrusions 13 limit and buffer the sliding plate 4, which can not only ensure the stability of the material barrel conveying, but also improve the roller conveyor speed. This solves the problems of instability at low speed and easy overturning at high speed in the existing device, achieving both high efficiency and safety. In addition, when the sliding plate 4 abuts against the protrusions 13, the inertia of the material barrel will cause the part of the buffer belt 6 that is in contact with it to move a certain distance. The part of the buffer belt 6 that is wound on the rotating wheel 5 will release a part of the buffer belt 6. Under the elastic action of multiple coil springs 11, it can play a buffering role. Moreover, the protrusions 13 move with the toothed synchronous belt 7, which can also reduce the instantaneous impact force between the protrusions 13 and the sliding plate 4. During the movement of several protrusions 13 with the toothed synchronous belt 7, they can also catch other sliding plates 4 that slide in.
[0025] When in use, the material barrel containing the raw materials is placed on the buffer belt 6. Two sets of inclined and symmetrically arranged slides 3 provide a stable support base for the material barrel. The support blocks between the slides 3 can improve the overall structural rigidity, avoid deformation under stress, and ensure the reliable operation of the sliding plate 4 and the buffer belt 6.
[0026] Unlike traditional roller conveyor systems that require constant control of roller 2 rotation and consume continuous energy, this device does not require control of roller 2 rotation. It can achieve automatic transfer by relying solely on the inclined slide 3 and the gravity of the material bucket itself, making it more energy-efficient and effective.
[0027] In the initial state, the sliding plate 4 is located at the starting end of the slide 3. The rough contact surface between the sliding plate 4 and the slide 3 forms a preset friction force, which keeps the sliding plate 4 and the buffer belt 6 stationary when there is no pressure from the material bucket, preventing random movement and ensuring the stability of the feeding position. After the material bucket is pressed on the buffer belt 6, the buffer belt 6 is squeezed to form a V-shaped support structure, which automatically centers and wraps the material bucket to limit its movement, suppressing shaking, deviation and tipping from the source, and providing a prerequisite guarantee for high-speed transfer.
[0028] Under the action of its own weight, the material bucket drives the buffer belt 6 and the sliding plate 4 to slide downward along the groove in the slide rail 3. The groove and the sliding plate 4 are matched to ensure smooth sliding and facilitate assembly and maintenance. During the sliding of the sliding plate 4, the rotating wheel 5 moves synchronously with the buffer belt 6. The annular groove 9 on the rotating wheel 5 positions and constrains the buffer belt 6 to prevent it from deviating or loosening, and to ensure reliable support.
[0029] When the sliding plate 4 moves to the end of the slide rail 3, it will abut against the protrusion 13 on the toothed synchronous belt 7 to achieve limit deceleration. At this time, under the inertia of the material barrel, the buffer belt 6 is further stretched, and the coil spring 11 undergoes elastic torsion. It absorbs the impact energy through elastic deformation to achieve flexible buffering and avoid rigid impact that could cause the material barrel to tip over or damage the equipment.
[0030] The toothed synchronous belt 7 is driven by a power source to rotate at a constant speed. The protrusion 13 moves continuously with the synchronous belt. On the one hand, it can reduce the instantaneous impact with the sliding plate 4. On the other hand, it can sequentially support the sliding plate 4 that slides in later, so as to achieve continuous and orderly buffering and limiting, and improve the overall transfer efficiency. The support wheel 12 supports the toothed synchronous belt 7 to prevent the synchronous belt from being concave due to force, and ensures that the position of the protrusion 13 is stable and the contact is reliable.
[0031] After buffering is complete, the sliding plate 4 and the material bucket are removed, the coil spring 11 is elastically reset, driving the rotating wheel 5 to rotate and the buffer belt 6 is tightened again. The sliding plate 4 can be reset to the starting end and enter the next working cycle. Alternatively, multiple sliding plates 4 and buffer belts 6 can be prepared in advance. The whole process does not require complex control or manual intervention. Relying on the weight of the material bucket, elastic reset and synchronous buffering, high-speed transfer is achieved while ensuring that the material bucket is stable and does not tip over throughout the process. This fundamentally solves the problem that existing devices cannot balance efficiency and stability.
