Description

Technical Field

[0001] This utility model specifically relates to a steering and conveying device. Background Technology

[0002] As core equipment in various mechanical fields requiring product transportation and route adjustment, such as logistics sorting, e-commerce warehousing, express delivery transit, packaging processing, machinery manufacturing, and food production, steering conveyor systems are crucial for the rapid diversion and route adjustment of goods, workpieces, and semi-finished products. Their performance directly affects production efficiency, space utilization, and operating costs. Existing steering conveyor systems have the following drawbacks: First, to achieve steering, traditional steering conveyor systems must rely on a combination structure of multiple conveyor belts and multiple steering mechanisms (e.g., bidirectional transfer requires 2 sets of steering mechanisms, 2 sets of receiving devices, and 2 conveyor belts). Furthermore, each conveyor belt requires an independent drive unit, resulting in numerous components and high costs. Second, when transferring products across belts, mismatched conveyor belt speeds and steering mechanism angle deviations can easily lead to jamming, tipping, or damage. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a steering conveying device with simplified structure, reduced parts, and improved steering reliability.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a steering and conveying device, comprising a frame, several steering mechanisms, and a single conveyor belt, wherein the several steering mechanisms are arranged sequentially at intervals, and the conveyor belt is sequentially wound around the steering mechanisms, and each pair of adjacent steering mechanisms divides the conveyor belt into a conveying section.

[0005] The beneficial effects of this invention are as follows: By adopting a combined structure of a single conveyor belt and multiple steering mechanisms, it replaces the complex configuration of traditional multi-belt, multi-steering systems, significantly reducing the number of independent drive devices and components, thereby lowering manufacturing costs and assembly complexity. This design avoids problems such as jamming, tipping, or product damage caused by speed mismatch and steering angle deviation in multi-belt systems, improving the stability and continuity of the conveying process. Furthermore, the integrated layout of a single conveyor belt optimizes space utilization, facilitates deployment in narrow or complex environments, simplifies maintenance procedures, and reduces potential failure points. As a preferred embodiment, the steering mechanism can employ a rotatable traction element and a steering element working in tandem. The traction element guides the conveyor belt to maintain linear motion in the conveying section, while the steering element achieves bending and turning at specific positions, thus achieving multi-directional flow splitting on a single belt without the need for additional transfer devices. As another preferred embodiment, the alternating arrangement of the conveying and steering sections allows products to flow continuously on the conveyor belt. The steering section smoothly transitions directions through an arc-shaped path, reducing the inertial impact of products during turning and improving adaptability to fragile or irregularly shaped workpieces.

[0006] Furthermore, the steering mechanism includes a first traction member and a second traction member arranged at intervals and rotatable. The steering mechanism also includes a steering member distributed between the first traction member and the second traction member and located below the middle of the first traction member and the second traction member. The steering member is rotatably mounted on the frame. A steering section is connected between each two adjacent conveying sections. The middle part of the steering section is wrapped around the outer periphery of the steering member. One end of the steering section passes through the middle of the first traction member and the second traction member and is wrapped around the first traction member. The other end of the steering section passes through the middle of the first traction member and the second traction member and is wrapped around the second traction member.

[0007] This steering mechanism design, through the coordinated layout of the first traction component, the second traction component, and the steering component, achieves an efficient transition of the conveyor belt between the conveying section and the steering section, avoiding the synchronization problems caused by the independent operation of multiple belts in traditional systems. The spaced arrangement of the first and second traction components provides stable tension support, ensuring the conveyor belt remains flat in straight sections, while the steering component, located in the lower center, guides the steering section to form a smooth arc, reducing belt stress and wear, thereby extending equipment life. Simultaneously, this structure reduces the risk of product deviation during steering, making it suitable for high-speed sorting scenarios. As a preferred approach, the steering component can employ a bushing combination with bearings, achieving low-resistance rotation through the rolling friction of the bearings, allowing the steering section to flexibly adapt to different steering angles without the need for complex adjustment mechanisms. Alternatively, the first and second traction components can be designed as a multi-bearing array layout to distribute the load and enhance belt guidance, ensuring the conveyor belt does not derail or slip during high-speed operation.

[0008] Furthermore, the steering component includes a steering positioning shaft and a steering sleeve sleeved on the steering positioning shaft. The steering sleeve is rotatably connected to the steering positioning shaft by installing several bearings. Both ends of the steering positioning shaft are connected to a first positioning plate. The first positioning plate has a first strip hole. The frame has a first screw positioning hole corresponding to the first strip hole.

[0009] This steering component structure achieves low-friction, high-precision rotation through bearing connection, reducing energy loss and noise. Simultaneously, the combination of the steering sleeve and steering positioning shaft enhances overall rigidity, making it suitable for high-load conditions. The first slotted hole and the first screw positioning hole provide flexible installation and adjustment capabilities, facilitating fine-tuning of the steering component's position on the frame, compensating for manufacturing or assembly errors, ensuring the alignment and steering accuracy of the conveyor belt path, thereby improving overall conveying efficiency. As a preferred option, the steering sleeve can be made of wear-resistant composite material, with multiple rows of rolling bearings embedded internally to distribute radial and axial forces, achieving smooth steering motion. The steering positioning shaft is fixed to the frame via the first positioning plate, forming a stable support frame. Alternatively, the design of the first slotted hole allows for lateral or longitudinal adjustment of the steering component during installation, with quick positioning achieved through screw tightening, avoiding the need for re-machining the frame and simplifying maintenance and upgrade processes.

[0010] Furthermore, the first traction component includes a traction shaft and a plurality of traction bearings sequentially sleeved on the traction shaft along its axial direction, with both ends of the traction shaft mounted on the frame; the second traction component has the same structure as the first traction component.

[0011] This traction component design, through multiple axially distributed traction bearings, achieves uniform support and low-friction guidance for the conveyor belt, reducing the risk of localized wear and deformation of the belt. The rigid mounting of the traction shaft ensures overall stability, making it suitable for high-speed or heavy-load conveying scenarios. It also simplifies manufacturing and assembly processes, as the second traction component has the same structure as the first, improving component interchangeability and maintenance convenience. As a preferred option, the traction bearings can be sealed deep groove ball bearings to resist dust and moisture corrosion, extending their service life, while the traction shaft is fixed to the frame at its ends, forming a reliable pivot point. Alternatively, an array arrangement of multiple traction bearings can distribute the tension of the conveyor belt, preventing vibration or misalignment during high-speed operation, thus ensuring smooth and accurate product conveying.

[0012] Furthermore, the frame is equipped with a main drive device for driving the conveyor belt. The main drive device includes a positioning frame, a servo motor mounted on the positioning frame, a transmission assembly linked to the output end of the servo motor, and a main drive shaft linked to the transmission assembly. Two sets of auxiliary transmission sleeves are symmetrically arranged on one side of the main drive shaft. A transmission positioning shaft is rotatably connected to the auxiliary transmission sleeve through a bearing. Both ends of the main drive shaft are rotatably mounted on the positioning frame. Both ends of the transmission positioning shaft are mounted on the positioning frame. The conveyor belt is sequentially wound around one set of auxiliary transmission sleeves, the main drive shaft, and the other set of auxiliary transmission sleeves.

[0013] This main drive unit, through the linkage of a servo motor and transmission components, provides precise speed and torque control to adapt to different conveying needs. The symmetrical layout of the main drive shaft and the auxiliary drive sleeve ensures uniform drive of the conveyor belt, avoiding belt slippage or uneven tension problems caused by single-point drive. The bearing connection within the auxiliary drive sleeve ensures low-resistance rotation, reducing energy loss, while the overall structure is integrated into the positioning frame, simplifying installation and commissioning. As a preferred option, the transmission components can employ a gear or belt drive system, achieving smooth acceleration and deceleration through frequency conversion control of the servo motor. The cooperation between the main drive shaft and the auxiliary drive sleeve can distribute the driving force, improving the stability of the conveyor belt during long-distance transport. Alternatively, the auxiliary drive sleeve can be designed as detachable for easy replacement or maintenance, while the transmission positioning shaft is connected to the sleeve via bearings, forming redundant support to ensure no vibration or misalignment occurs during high-speed operation.

[0014] Furthermore, a second screw positioning hole is provided on the upper side of the positioning frame, and a second positioning plate is fixed on the frame corresponding to the upper side of the positioning frame. The second positioning plate is provided with a second strip hole corresponding to the second screw positioning hole.

[0015] This design, where the positioning bracket connects to the frame, utilizes the combination of the second screw positioning hole and the second slotted hole to enable rapid installation and fine-tuning of the main drive unit. This facilitates alignment and fixation during equipment deployment, reducing assembly time and errors. The second slotted hole provides adjustment leeway to accommodate variations in frame tolerances, ensuring alignment between the main drive shaft and the conveyor belt, thereby optimizing drive efficiency and lifespan. As a preferred option, the second positioning plate can be welded or bolted to the frame, forming a rigid connection, while the second slotted hole allows the positioning bracket to move longitudinally or laterally during installation, achieving precise positioning through screw locking. Alternatively, the combination of the second screw positioning hole and the second slotted hole can compensate for displacement caused by thermal expansion or vibration, maintaining long-term stability of the drive system without frequent adjustments.

[0016] Furthermore, a set of support plates is provided at each pair of adjacent conveyor sections, and the support plates are detachably installed on the frame by screws.

[0017] This support plate design, through its detachable installation, provides additional support for the conveyor belt at the junction of conveyor sections, preventing sagging or deformation of the belt due to load or speed changes, thereby maintaining the flatness and stability of the conveyor path. The support plate reduces vibration and noise, making it suitable for transporting precision workpieces or fragile products, while also facilitating daily cleaning and maintenance, as the screw connection allows for quick disassembly and replacement. As a preferred option, the support plate can be made of wear-resistant steel plate with a smooth surface to reduce friction, and fixed to the frame with screws to form a modular structure, allowing for easy adjustment of the support point position according to conveying requirements. Alternatively, the support plate can be designed as curved or flat to accommodate different conveyor section angles, ensuring that the conveyor belt does not experience stress concentration in the turning transition zone, thereby extending belt life and improving overall reliability.

[0018] The beneficial effects of this utility model are: In response to the complex configuration of traditional devices with "multiple belts and multiple steering mechanisms, and independent drive", this utility model adopts a combination of a single conveyor belt and multiple steering mechanisms, which greatly reduces the number of independent drive devices and parts, and reduces manufacturing costs and assembly complexity.

[0019] To avoid the problems of jamming, tipping or damage caused by "speed mismatch and angle deviation" during traditional cross-belt transfer, the conveyor belt is guided to form a smooth turning section through the steering mechanism (first / second traction component, steering component), which improves the stability and continuity of the conveying, and is especially suitable for high-speed sorting scenarios.

[0020] The integrated layout of a single conveyor belt saves space and facilitates deployment in narrow environments; the slotted design of the steering components allows for fine-tuning of the position, compensating for assembly errors, and eliminating the need to rework the frame.

[0021] The steering component uses bearing connection to achieve low-friction rotation, which is suitable for heavy-load conditions; the multi-bearing array layout of the traction component distributes the load, prevents the belt from running off-track, and improves the adaptability to fragile / irregularly shaped workpieces.

Its technical effect is to achieve smooth steering of the conveyor belt 3, reduce friction and wear, and improve conveying efficiency. The conveyor belt 3 is sequentially wound around the steering mechanism 2. Each pair of adjacent steering mechanisms 2 divides the conveyor belt 3 into a conveying section 31. A steering section 32 is connected between adjacent conveying sections 31. The middle part of the steering section 32 is wound around the outer periphery of the steering member 23. One end of the steering section 32 passes through the middle of the first traction member 21 and the second traction member 22 and is wound around the first traction member 21. The other end also passes through and is wound around the second traction member 22. The technical effect is to form a continuous conveying path, adapt to multi-directional transportation needs, and improve space utilization.

[0026] The steering component 23 includes a steering positioning shaft 231 and a steering sleeve 232 sleeved on the steering positioning shaft 231. The steering sleeve 232 is rotatably connected to the steering positioning shaft 231 by installing several bearings, which reduces rotational resistance and extends service life. Both ends of the steering positioning shaft 231 are connected to first positioning plates 234. The first positioning plates 234 have first slotted holes 235, and the frame 1 has first screw positioning holes 11 corresponding to the first slotted holes 235. This facilitates adjustment and fixing of the steering component 23, adapting to different installation requirements. The first traction component 21 includes a traction shaft 211 and several traction bearings 212 sequentially sleeved on the traction shaft 211 along its axial direction. Both ends of the traction shaft 211 are mounted on the frame 1. The second traction component 22 has the same structure as the first traction component 21, including a similar traction shaft and traction bearings. Its technical effect is to provide stable traction force, ensure smooth operation of the conveyor belt 3, and reduce slippage.

A transmission positioning shaft 452 is rotatably connected to the auxiliary transmission sleeve 45 through a bearing. Both ends of the main drive shaft 44 are rotatably mounted on the positioning frame 41, and both ends of the transmission positioning shaft 452 are mounted on the positioning frame 41. The conveyor belt 3 is wound around one set of auxiliary transmission sleeves 45, the main drive shaft 44, and the other set of auxiliary transmission sleeves 45 in sequence.

A set of support plates 5 is provided at each pair of adjacent conveyor sections 31. The support plates 5 are detachably installed on the frame 1 by screws. The technical effect is to provide additional support, prevent the conveyor belt 3 from sagging, and ensure conveying stability.

[0028] The working principle of the steering conveyor is as follows: The servo motor 42 drives the main drive shaft 44 to rotate through the transmission assembly 43, which in turn drives the conveyor belt 3 to move. When the conveyor belt 3 passes through the steering mechanism 2, the first traction member 21 and the second traction member 22 guide the conveyor belt 3 to turn by rotation. The steering member 23 assists in completing the mid-section turning, forming a continuous conveying section 31 and a turning section 32, realizing multi-directional material conveying. The support plate 5 provides support at key positions to prevent the conveyor belt 3 from deforming. The entire device is fixed by the frame 1 to ensure smooth operation. During assembly, first install the steering mechanism 2 and the main drive device 4 onto the frame 1, adjust the positions of the first positioning plate 234 and the second positioning plate 12 to align the screw holes, then fix the conveyor belt 3, and finally install the support plate 5 to complete the overall assembly.
