Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, in particular to a non-powered and decelerating magnetic roller for preventing material impact. Background Art

[0002] Inclined conveyor lines are often seen in major industries such as transportation, packaging, handling, logistics and textiles. For example, when unloading luggage at an airport, the unloading roller conveyor is inclined. In inclined conveying, due to the influence of gravity, the speed difference is formed, so that the materials are easy to collide with each other. In this process, the conveyor belt cannot provide limited buffering for the materials, causing wear and tear on the materials and conveyor rollers. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that materials are easily impacted and have no buffering during the existing roller slope transportation. A non-powered and decelerating magnetic roller is provided to prevent material impact. The function of buffering is provided during the material transportation process to avoid the speed difference caused by the influence of the material's own weight and the collision of the materials. The roller has the same long service life as the conveying roller and will not generate external magnetic discharge force.

The plastic end cover is connected to the iron sleeve, and the outer diameter of the iron sleeve is smaller than the inner diameter of the cylinder.

[0008] The magnet fixing hexagonal sleeves are provided as a pair, which are relatively sleeved on the central axis and form an interference fit with the central axis. One end of each magnet fixing hexagonal sleeve is provided with a group of gears, and the other end is provided as a small head end. A magnet adsorption hexagonal body is connected between the two magnet fixing hexagonal sleeves, and six magnets are connected to the magnet adsorption hexagonal body. Each magnet is provided between the gears of the two magnet fixing hexagonal sleeves, so as to keep the six magnets separated and evenly distributed in the circumferential direction.

[0009] The small end of each magnet-fixed hexagonal sleeve is connected to a deep groove ball bearing, and the two form an interference fit. The deep groove ball bearing on the left is arranged in a bearing fixing seat, and the deep groove ball bearing on the right is arranged in a toothed bearing seat. A copper sleeve is connected between the bearing fixing seat and the toothed bearing seat. The magnet-fixed hexagonal sleeve, the magnet adsorption hexagon and the magnet are all arranged in the copper sleeve. The copper sleeve is arranged in the iron sleeve and its outer diameter is smaller than the inner diameter of the iron sleeve to avoid friction and wear.

[0010] The toothed bearing seat is located at the rightmost end of the magnetic damper, and the tooth groove at the right end thereof is meshed with the tooth claw of the bearing seat assembly so as to drive the copper sleeve to rotate simultaneously when the cylinder rotates.

[0011] Furthermore, the bearing seat assembly includes a plastic bearing seat, a first bearing and a transparent cover that cooperate with each other. The hexagonal hole of the transparent cover and the central axis are interference fit, the outer diameter of the transparent cover and the inner ring of the first bearing are interference fit, the first bearing is connected to the plastic bearing seat, and an interference fit is formed between the plastic bearing seat and the cylinder through the shrink tube mouth.

[0012] Furthermore, the teeth and claws are connected to the inner side of the plastic bearing seat, and the teeth and claws are evenly distributed radially outwards with the center line of the plastic bearing seat as the center.

[0013] Furthermore, one end of the return spring presses against the first punch ear, and the other end presses against the transparent cover of the bearing seat assembly.

[0014] Furthermore, the teeth and claws of the bearing seat assembly are arranged on the side of the plastic bearing seat facing the cylinder, and the tooth grooves of the toothed bearing seat are correspondingly meshed with the teeth and claws of the plastic bearing seat.

[0015] Furthermore, the central axis is a stainless steel rod to prevent magnetic conduction.

[0016] Furthermore, the magnet fixing hexagonal sleeve is a plastic sleeve including six gears, the magnet adsorption hexagonal body is an iron block, and the hexagonal hole of the magnet fixing hexagonal sleeve cooperates with the outer hexagonal surface of the magnet adsorption hexagonal body to be used for axial positioning and radial positioning of the magnet adsorption hexagonal body.

[0017] Furthermore, the axes of the bearing seat assembly, the magnetic damper, the cylinder and the central axis coincide with each other.

[0018] In the technical solution of the present invention, when the toothed bearing seat and the plastic bearing seat are meshed with each other, the rotation of the cylinder will drive the copper sleeve to rotate at the same time, and the magnets are distributed as follows: Figure 5As shown, at this time, an annular magnetic field line is formed around the magnet; and the copper sleeve is a diamagnetic material, and its rotation forms a movement that cuts the magnetic field line, that is, an induced current is generated. The magnetic field generated by this current must offset the original magnetic field, that is, when the closed loop cuts the magnetic field line in the magnetic field, it must be resisted by the original magnetic field; therefore, when the toothed bearing seat and the plastic bearing seat are meshed with each other, magnetic resistance is generated. The device of the present invention provides a buffering function during the material conveying process, avoiding the speed difference caused by the weight of the material and colliding with each other. The product has a compact structure, realizes maintenance-free and wear-free operation, has the same long service life as the conveying roller, and does not generate external magnetic discharge force.

[0030] The central axis 2 is connected with a first punching ear 4 and a second punching ear 5 from left to right in sequence. A return spring 6 is sleeved on the left side of the central axis 2. One end of the return spring 6 presses against the first punching ear 4 and the other end presses against the transparent cover 33 of the bearing seat assembly 3.

[0031] See also Figure 1 , Figures 3-5 A magnetic damper 7 is provided on the right side of the middle shaft 2, and the magnetic damper 7 includes a plastic end cover 71, an iron sleeve 72, a deep groove ball bearing 73, a bearing fixing seat 74, a magnet fixing hexagonal sleeve 75, a copper sleeve 76, a magnet adsorption hexagonal body 77, a magnet 78 and a toothed bearing seat 79;

[0032] The plastic end cap 71 is sleeved on the central axis 2 and is located just on the right side of the second punching ear 5. The plastic end cap 71 and the central axis 2 are in interference fit. The plastic end cap 71 is connected to the iron sleeve 72. The outer diameter of the iron sleeve 72 is smaller than the inner diameter of the cylinder 1.

[0033] The magnet fixing hexagonal sleeve 75 is configured as a pair of plastic sleeves, which are relatively sleeved on the central axis 2 and form an interference fit with the central axis 2. One end of each magnet fixing hexagonal sleeve 75 is provided with six gears 75a, and the other end is configured as a small head end 75b;

[0034] A magnet adsorption hexagonal body 77 is connected between the two magnet fixed hexagonal sleeves 75. The magnet adsorption hexagonal body 77 is an iron block. The hexagonal hole of the magnet fixed hexagonal sleeve 75 cooperates with the outer hexagonal surface of the magnet adsorption hexagonal body 77 to be used for axial positioning and radial positioning of the magnet adsorption hexagonal body.

[0035] There are six magnets 78 connected to the magnet adsorption hexagon 77, and the magnets are distributed in the form of Figure 5 As shown, each magnet 78 is disposed between the gears 75a of two magnet fixing hexagonal sleeves 75, so as to keep the six magnets separated and evenly positioned in the circumferential direction;

[0036] The small end 75b of each magnet fixed hexagonal sleeve 75 is connected to a deep groove ball bearing 73, and the two form an interference fit. The deep groove ball bearing 73 on the left is arranged in a bearing fixing seat 74, and the deep groove ball bearing 73 on the right is arranged in a toothed bearing seat 79.
