Description
Technical Field
[0001] This utility model belongs to the technical field of smooth-surfaced deflector pulleys for belt conveyors, specifically relating to a smooth-surfaced deflector pulley for preventing belt misalignment. Background Technology
[0002] In the field of belt conveyors, preventing belt misalignment is a critical issue. In practical applications, belts are prone to misalignment due to various reasons such as uneven belt tension, uneven material loading, roller installation errors, or wear. Misalignment causes severe friction between the belt edge and the frame, resulting in premature belt wear, tearing, and even production accidents such as material spillage. To solve the misalignment problem, it is usually necessary to install additional self-aligning idlers, vertical rollers, and other correction devices, which are complex and sometimes unsatisfactory.
[0003] Traditional smooth-surfaced deflector pulleys are one-piece rollers with a smooth cylindrical surface of uniform diameter. These pulleys only serve to guide and increase the wrap angle; they do not prevent belt misalignment. Another technical solution attempts to create a one-piece "drum-shaped" roller (with a slightly larger diameter in the middle than at the ends), which offers some correction, but its protrusion remains fixed. Once worn or if operating conditions change (such as replacing with a different belt model), the entire roller must be replaced, resulting in high maintenance costs and poor flexibility. Furthermore, the overall machining of this type of pulley is more difficult than that of a regular roller, leading to higher manufacturing costs.
[0004] Traditional smooth-surface steering pulleys have a single function and cannot prevent belt misalignment. On the other hand, integral drum rollers with anti-misalignment function have drawbacks such as non-adjustability, high replacement and maintenance costs, and poor flexibility. Therefore, we propose a smooth-surface steering pulley to prevent belt misalignment. Utility Model Content
[0005] To address the shortcomings of traditional smooth-surface steering pulleys, which offer limited functionality and cannot prevent belt misalignment, and the limitations of integral drum-shaped rollers with anti-misalignment functions, such as lack of adjustability, high replacement and maintenance costs, and poor flexibility, this invention provides a smooth-surface steering pulley designed to prevent belt misalignment.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a smooth-surfaced deflection wheel for preventing belt misalignment, comprising a base, a smooth-surfaced wheel, and a traction wheel. A head wheel is installed on one side of the base, a tail wheel is installed on the other side of the base, smooth-surfaced wheels are installed on both sides of the base, and a traction wheel is sleeved on the outer middle of the smooth-surfaced wheel.
[0007] The inner wall of the traction wheel is fixed with a locking block, and the outer wall of the smooth wheel is correspondingly provided with an installation slot. One end of the connection end of the two traction wheels is fixed with a plug rod and a docking post, and the other end is provided with a plug hole and a docking groove. The end of the traction wheel near the docking groove is provided with a positioning screw hole, and a fixing bolt is installed in the positioning screw hole.
[0008] In a preferred embodiment of the smooth-surfaced redirecting wheel for preventing belt misalignment according to this utility model, the diameter of the traction wheel is larger than the diameter of the smooth-surfaced wheel.
[0009] As a preferred embodiment of the smooth-surfaced redirecting wheel for preventing belt misalignment according to this utility model, the locking block is adapted to the mounting slot.
[0010] As a preferred embodiment of the smooth-surfaced redirecting wheel for preventing belt misalignment according to this utility model, the plug rod is adapted to the plug hole, and the docking post is adapted to the docking groove.
[0011] As a preferred embodiment of the smooth-surfaced redirecting wheel for preventing belt misalignment according to this utility model, the fixing bolt passes through the positioning screw hole and extends into the docking column to fix the two traction wheels together.
[0012] As a preferred embodiment of the smooth-surfaced guide wheel for preventing belt misalignment according to this utility model, the traction wheel and the smooth-surfaced wheel are detachably connected, and the width and diameter of the traction wheel can be replaced and adjusted to adapt to belts of different widths and provide different correction forces.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By adding a traction wheel with a larger diameter in the middle, the central friction force is actively increased to form an effective traction belt, which can automatically and dynamically correct belt deviation, ensuring production safety and continuity. The traction wheel adopts a split and detachable design, and can be quickly installed and separated through the clamp, slot and plug structure. This design allows users to easily replace different specifications of traction wheel modules according to actual needs, thereby realizing flexible adjustment of the deviation correction capability, greatly enhancing the adaptability of the equipment, and preventing the problems of the integral drum roller being non-adjustable, having high replacement and maintenance costs, and poor flexibility.

[0021] 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.
[0022] Example 1
[0023] like Figures 1-5 As shown;
[0024] A smooth-surfaced deflector for preventing belt misalignment includes a base 1, smooth-surfaced wheels 4, and a traction wheel 5. A head wheel 2 is installed on one side of the base 1, and a tail wheel 3 is installed on the other side of the base 1. Smooth-surfaced wheels 4 are installed on both sides of the base 1. A traction wheel 5 is fitted on the outer side of the middle of the smooth-surfaced wheels 4. A locking block 8 is fixed to the inner wall of the traction wheel 5, and a mounting slot 7 is correspondingly opened on the outer wall of the smooth-surfaced wheels 4. A plug rod 10 and a docking post 12 are fixed to one end of the connection end of the two traction wheels 5, and a plug hole 9 and a docking groove 11 are opened on the other end. A positioning screw hole 13 is opened on the end of the traction wheel 5 near the docking groove 11, and a fixing bolt 6 is installed in the positioning screw hole 13.
[0025] In this implementation plan, by adding a larger diameter traction wheel 5 in the middle, the central friction is actively increased to form an effective traction belt, which can automatically and dynamically correct belt misalignment, ensuring production safety and continuity. The traction wheel 5 adopts a split and detachable design, and can be quickly installed and separated through the locking block 8, the locking slot and the plug-in structure. This design allows users to easily replace different specifications of traction wheel 5 modules according to actual needs, thereby realizing flexible adjustment of the correction capability and greatly enhancing the adaptability of the equipment.
[0026] In an optional embodiment, the diameter of the traction wheel 5 is larger than the diameter of the smooth wheel 4.
[0027] In this implementation scheme: the increased diameter causes a raised friction ring to form in the middle of the traction wheel 5, which significantly increases the friction in the central area of the belt. According to the belt drive characteristics, the belt will automatically center towards the central area with greater friction, thereby realizing an automatic, dynamic, and external power-free correction function, effectively preventing belt deviation and ensuring stable operation of the conveyor line.
[0028] In an optional embodiment, the card block 8 is adapted to the mounting slot 7.
[0029] In this implementation scheme: the cooperation between the locking block 8 and the locking slot enables rapid and accurate radial positioning and circumferential limiting between the traction wheel 5 and the smooth wheel 4, ensuring that the traction wheel 5 will not rotate or shift relative to the smooth wheel 4 after installation, thus guaranteeing the reliability of power transmission and the stability of the structure, and providing a foundation for subsequent axial connection.
[0030] In an optional embodiment, the plug rod 10 is adapted to the plug hole 9, and the mating post 12 is adapted to the mating groove 11.
[0031] In this implementation scheme: the plug-in and docking structure design enables the two semi-circular traction wheels 5 to achieve rapid and precise axial alignment when they are closed, ensuring that the two components can be seamlessly spliced into a perfect ring, avoiding belt wear, vibration or abnormal noise caused by misalignment, and ensuring the smooth and reliable operation of the entire device.
[0032] In an optional embodiment, the fixing bolt 6 passes through the positioning screw hole 13 and extends into the docking post 12 to fix the two traction wheels 5 together.
[0033] In this implementation plan: the bolted connection provides a strong locking force, which is the key to ensuring that the two traction wheels 5 will not loosen under high-speed operation and vibration conditions. Moreover, the bolted connection is extremely convenient to install and remove, and can be completed with ordinary tools, which greatly simplifies the replacement and maintenance process and reduces the skill requirements and labor intensity of the operators.
[0034] In an optional embodiment, the traction wheel 5 is detachably connected to the smooth wheel 4, and the width and diameter of the traction wheel 5 are interchangeable and adjustable to accommodate belts of different widths and provide different corrective forces.
[0035] In this implementation scheme: the detachable connection transforms the traction wheel 5 from a fixed component into an independent, quickly replaceable modular functional unit. When the traction wheel 5 wears out, there is no need to replace the expensive smooth wheel 4 assembly; only this module needs to be replaced, significantly reducing maintenance costs and spare parts inventory costs. Furthermore, users can select a traction wheel 5 of the appropriate width based on the actual belt width used to ensure effective coverage. At the same time, different diameter traction wheel 5 modules can be selected based on the required correction force, such as different load and speed conditions.
[0036] Working principle:
[0037] First, the belt is wound around the head pulley 2 and tail pulley 3 mounted on the base 1 for transmission. The smooth wheel 4 is installed on both sides inside the base 1, mainly for guiding and supporting.
[0038] The two semi-circular traction wheels 5 are radially positioned by engaging the internal locking blocks 8 with the mounting slots 7 on the outer wall of the smooth wheel 4. The two traction wheels 5 are precisely aligned and axially connected by inserting the plug rod 10 at one end into the plug hole 9 at the other end and embedding the docking post 12 into the docking groove 11. After alignment, the fixing bolt 6 is passed through the positioning screw hole 13 on the traction wheel 5 and screwed into the docking post 12 to firmly lock the two halves of the traction wheel 5 into a whole and fix it on the smooth wheel 4.
[0039] On the outer middle of the smooth pulley 4, a traction pulley 5 consisting of two halves is fitted. The diameter of the traction pulley 5 is larger than that of the smooth pulley 4 on both sides, thus forming a raised "friction ring" in the middle of the pulley. This raised friction ring contacts the middle of the belt more tightly, significantly increasing the friction in the central area of the belt operation, forming a strong central traction belt. According to the belt drive characteristics, the belt has a tendency to automatically center itself towards the area with higher linear speed and greater friction. Therefore, when the belt deviates, it will be automatically pulled back to the center position by this high-friction central traction belt, realizing a dynamic and automatic correction function.
[0040] When it is necessary to adapt to belts of different widths or adjust the correction force, simply remove the fixing bolts 6 to separate the entire traction wheel 5 assembly from the smooth wheel 4. Then, traction wheel 5 modules of different widths or diameters can be replaced, thereby quickly adjusting the working surface profile of the smooth steering wheel.
[0041] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
