Description

Technical Field

[0001] The utility model relates to the technical field of industrial equipment, in particular to a roller system with magnetic suspension friction reduction. Background Art

[0002] A roller system is a mechanical system widely used in logistics, manufacturing, packaging and many other industrial fields; it usually consists of a series of rollers arranged horizontally or tilted, which can rotate independently to transport, guide or position various items.

[0003] For example, announcement number CN220765539U discloses a roller belt structure for a palletizer, which uses a conveyor belt that rotates in the opposite direction. After the material is transmitted to the material smooth transmission mechanism through the material transmission mechanism, the material will slowly move to the material smooth transmission mechanism because the movement speeds of the two conveyor belts are the same but the contact areas are different; for example, announcement number CN219278626U discloses a lightweight, pressure-resistant, unpowered roller, which drives the pull rod to move by pulling a circular pull plate, and at the same time, the circular limit plate blocks the limit block, and then the extended roller is pulled from the outer wall of the roller body, thereby realizing the length of the roller that can be adjusted to multiple sizes, and its structure is tightly connected and firmly connected, and is more stable during adjustment and use.

[0004] The above two groups of existing technologies output power to the drum manually and electrically respectively. During this process, the transmission component is in a rigid stress state. In long-term use, the loss caused by friction is relatively large. Therefore, we propose a drum system based on electromagnetic mutual induction as a power source, aiming to solve the problem of high energy consumption and high friction loss in drum rotation. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The purpose of the utility model is to provide a roller system with magnetic levitation friction reduction, so as to solve the problem that the transmission component proposed in the above background technology is in a rigid stress state, and the loss caused by friction is large during long-term use. For this reason, we propose a roller system based on electromagnetic mutual induction as a power source, aiming to solve the problem of large energy consumption and high friction loss in roller rotation.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roller system with magnetic suspension friction reduction, comprising a main body mechanism, a braking mechanism and a protective mechanism, wherein the braking mechanism is located at the inner end of the main body mechanism, and the protective mechanism is located at the outer end of the main body mechanism, wherein the main body mechanism comprises a supporting shell, a roller body, a rotor assembly and a magnetic induction coil, wherein the roller body is movably mounted on the outer end of the slotted surface of the supporting shell; the rotor assembly is fixedly mounted at the head and tail ends of the roller body to drive the roller body to rotate; the magnetic induction coil is fixedly mounted on the inner wall of the roller body and the rotor assembly;

[0009] The main structure also includes a bearing bracket, a stator assembly and a transformer. The bearing bracket is fixedly installed inside the rotor assembly to connect the magnetic induction coil inside the rotor assembly; the stator assembly is fixedly installed on the inner end of the support shell, and the transformer is fixedly installed on the lower end of the stator assembly.

[0010] Preferably, the braking mechanism includes a transmission belt part, a control panel, a first information processing part, a power module, a second information processing part, an angular velocity sensor and a battery part, and the transmission belt part is fixedly mounted on the inner end of the left grooved surface of the support shell, and the transmission belt part includes but is not limited to a transmission belt body and an electric drive part.

[0011] Preferably, the control panel is fixedly mounted on the front surface of the supporting shell, the first information processing unit is fixedly mounted inside the supporting shell, and the first information processing unit includes but is not limited to an embedded processor and a wireless receiver; the power supply module is fixedly mounted on the outer end of the first information processing unit.

[0012] Preferably, the second information processing unit is movably installed inside the drum body, and the second information processing unit includes but is not limited to a circuit board and a radio frequency module; the angular velocity sensor is fixedly installed at the inner end of the second information processing unit, and the battery unit is fixedly installed at the lower end of the second information processing unit.

[0013] Preferably, the protection mechanism comprises a limit plate, a rubber pad, a silicon steel sheet and an electrode sheet, the limit plate is fixedly arranged on the upper end of the support shell, and the rubber pad is fixedly arranged on the outer end of the upper surface of the limit plate.

[0014] Preferably, one end of the silicon steel sheet is connected to the drum body, and the other end is connected to the rotor assembly; the electrode sheet is fixedly arranged at the inner end of the rotor assembly.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The roller system with magnetic suspension friction reduction is fixedly installed through the main body mechanism. When the transformer changes the voltage strength of the input stator assembly, the stator assembly generates a magnetic field due to electromagnetic mutual induction. The magnetic field lines pass through the magnetic induction coil in the roller body, causing the roller body to generate a unidirectional magnetic force, so that the roller body floats in the support shell to stay away from the stator assembly. Two groups of symmetrically arranged rotor assemblies are used to balance and orient the roller body. At the same time, the magnetic induction coil in the rotor assembly is rotated along the bearing bracket under the force of the magnetic field, thereby driving the roller body to rotate. In this process, energy consumption and wear caused by mechanical transmission are reduced, making the equipment more stable during production.

[0017] 2. The roller system with magnetic suspension friction reduction is fixedly installed by the brake mechanism. When the product enters the supporting shell along the transmission belt, the user inputs the command to the first information processing unit through the control panel to control the power supply voltage of the power module to the transformer. At the same time, the kinetic energy generated by the rotation of the roller body is generated by the magnetic field interaction between the rotor assembly and the stator assembly to generate electricity, which is supplied to the battery unit through the second information processing unit, so that the energy consumption generated by the movement of the roller body and the calculation of the angular velocity sensor is provided passively, which effectively improves the energy saving of the roller system;

[0018] 3. The roller system with magnetic suspension friction reduction is fixedly installed by the protective mechanism. The radial direction of the roller body is larger than the rotor assembly. When the equipment is in the start-stop stage, the rubber pad protects and supports the roller body. The use of silicon steel sheets minimizes the magnetic field interference between the rotor assembly and the stator assembly to ensure the stable operation of the roller system.
