Description

Technical Field

[0001] The utility model relates to the field of electric rollers, in particular to an integrated permanent magnet variable frequency electric roller. Background Art

[0002] Traditional electric drums place the motor and reducer together inside the drum body, with a limited speed range, and the gears and other devices have disadvantages such as easy wear, high noise, large volume, low efficiency, and high maintenance costs. For this reason, permanent magnet electric drums came into being. By replacing the motor and reducer with the internal magnetic system, the disadvantages of traditional electric drums such as high noise, large volume, low efficiency, and high maintenance costs are overcome. They are mainly used in belt conveyors and driven by the rotation of the drum, that is, the belt and the drum are in direct contact to form friction.

[0003] The existing integrated permanent magnet variable frequency electric roller generally uses the width of the roller itself to carry and transport objects. When it is necessary to carry objects of a larger width, the permanent magnet electric roller cannot adjust the diameter of the roller to meet the use requirements. In order to reduce wear, a coating is usually provided on the surface of the roller. After the coating is worn, it needs to be repaired as a whole, and the repair efficiency is low and the time is long. Utility Model Content

[0009] A further improvement of the technical solution of the utility model is that the inner support strips are arranged laterally and equidistantly inside the upper roller and the lower roller, and the inner support strips are attached to the outside of the permanent magnet electric drum body.

[0010] A further improvement of the technical solution of the utility model is that: both left and right sides of the upper roller and the lower roller are provided with limiting edges, and the anti-slip sleeve is arranged on the inner side of the limiting edges.

[0011] A further improvement of the technical solution of the utility model is that the outer diameter of the anti-slip rubber bag is larger than the limiting edge setting.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides an integrated permanent magnet variable frequency electric drum, comprising a permanent magnet electric drum body 1 and side end covers 2 arranged on both sides of the permanent magnet electric drum body 1, and the side end covers 2 are provided with limit slots 21 on the upper and lower sides inside the side end covers 2, and the inner part of the limit slots 21 is movably installed with an external expansion cylinder 3 located outside the permanent magnet electric drum body 1, and the outer part of the external expansion cylinder 3 is fixedly installed with an anti-slip sleeve 4.

[0024] By installing the external expansion cylinder 3 in the limiting slot 21 on the basis of the permanent magnet electric drum body 1, the external expansion cylinder 3 is arranged on the outside of the permanent magnet electric drum body 1. When the permanent magnet electric drum body 1 remains unchanged, the diameter size of the permanent magnet electric drum body 1 is expanded by using external expansion cylinders 3 of different sizes, so as to adjust the diameter size of the permanent magnet electric drum body 1 as needed to meet the transportation requirements of different objects. At the same time, when the anti-slip sleeve 4 arranged on the external expansion cylinder 3 is severely worn during use with the belt conveyor, the external expansion cylinder 3 can be replaced and disassembled to remove the anti-slip sleeve 4 from the outside of the external expansion cylinder 3 for replacement, which is convenient for maintenance and improves the repair efficiency.

[0025] like Figure 2 As shown, the external expansion cylinder 3 includes an upper roller 31 and a lower roller 32, and the left and right sides of the inner sides of the upper roller 31 and the lower roller 32 are fixedly connected with side clamping plates 33, the inner sides of the upper roller 31 and the lower roller 32 are fixedly connected with inner support bars 34, the outer sides of the side clamping plates 33 are fixedly connected with fixed ear plates 37, and the internal threads of the fixed ear plates 37 are connected with anti-detachment bolts 38.

[0026] The upper roller 31 and the lower roller 32 are clamped on the outside of the permanent magnet electric drum body 1 by using the side clamping plates 33 on both sides thereof to align with the limiting grooves 21 provided on the upper and lower sides of the side end cover 2, and the side clamping plates 33 are clamped into the limiting grooves 21, so that the upper roller 31 and the lower roller 32 are clamped on the outside of the permanent magnet electric drum body 1, so that the inner support bar 34 is in contact with the outer wall of the permanent magnet electric drum body 1 to provide support for the upper roller 31 and the lower roller 32, and the anti-slip bolts 38 are used to penetrate the fixing ear plates 37 on the outer sides of the opposite side clamping plates 33 from above to lock the fixing ear plates 37, so that the upper roller 31 and the lower roller 32 are connected and clamped on the outside of the permanent magnet electric drum body 1, thereby adjusting the diameter size of the permanent magnet electric drum body 1 to meet the conveying requirements of different objects.

[0027] like Figure 5 As shown, the anti-skid cover 4 includes an anti-skid rubber coating 41 , and a connecting surface 42 is provided on the inner side of the anti-skid rubber coating 41 . The anti-skid rubber coating 41 is respectively bonded to the outside of the upper cover roller 31 and the lower cover roller 32 through the connecting surface 42 .

[0028] The anti-skid rubber bag 41 is bonded to the outside of the upper roller 31 and the lower roller 32 by the connecting surface 42, and the anti-skid rubber bag 41 is in contact and frictionally transmitted with the belt. When the anti-skid rubber bag 41 is worn too much, the anti-skid rubber bag 41 can be peeled off from the upper roller 31 and the lower roller 32 through the connecting surface 42 for quick replacement, without the need for overall repair, thereby improving the repair efficiency.

[0029] like Figure 2 and Figure 3 As shown, a positioning convex edge 35 is provided on the top of the lower roller 32 , and a docking groove 36 is provided on the bottom of the upper roller 31 . The positioning convex edge 35 is movably engaged in the interior of the docking groove 36 .

[0030] When the upper roller 31 and the lower roller 32 are aligned and connected, the alignment protrusion 35 is inserted into the docking groove 36 to limit the upper roller 31 and the lower roller 32, thereby improving the connection accuracy.

[0031] like Figure 2 and Figure 3 As shown, the inner support bars 34 are arranged laterally and equidistantly inside the upper roller 31 and the lower roller 32 , and the inner support bars 34 are attached to the outside of the permanent magnet electric drum body 1 .

[0032] The transversely arranged inner support bar 34 is attached to the outside of the permanent magnet electric drum body 1 , and the inner support bar 34 provides stable support to the upper roller 31 and the lower roller 32 to ensure stable conveying of objects.

[0033] like Figure 4 and Figure 5 As shown, both left and right sides of the upper roller 31 and the lower roller 32 are provided with limiting edges 39 , and the anti-slip sleeve 4 is arranged inside the limiting edges 39 .

[0034] The outer diameter of the anti-skid rubber coating 41 is larger than the limiting edge 39 .

[0035] The anti-skid sleeve 4 is arranged inside the limiting edge 39 and the outer diameter of the anti-skid rubber bag 41 is larger than the limiting edge 39 , so that the anti-skid rubber bag 41 contacts with the belt for transmission.

[0036] like Figure 5 As shown, the outside of the anti-slip rubber coating 41 is provided with a concave-convex surface 43 .

[0037] The friction force is increased by providing the concave-convex surface 43 .

[0038] The following is a detailed description of the working principle of the integrated permanent magnet variable frequency electric drum.

[0039] like Figures 1 to 5 As shown, by selecting a suitable external expansion cylinder 3, the upper roller 31 and the lower roller 32 respectively use the side clamping plates 33 on both sides to align the limiting grooves 21 set on the upper and lower sides of the side end cover 2, and by clamping the side clamping plates 33 into the limiting grooves 21, the upper roller 31 and the lower roller 32 are clamped on the outside of the permanent magnet electric drum body 1, and the alignment convex edge 35 on the top of the lower roller 32 is clamped into the docking groove 36 at the bottom of the upper roller 31 for docking, and at the same time, the inner support bar 34 is fitted with the outer wall of the permanent magnet electric drum body 1 to provide support for the upper roller 31 and the lower roller 32, and the upper roller 31 and the lower roller 32 are connected by using the anti-slip bolts 38 to penetrate the fixed ear plates 37 on the outside of the opposite side clamping plates 33 from above the fixed ear plates 37 to lock. It is connected and fixed to the outside of the permanent magnet electric drum body 1, so that the size and diameter of the permanent magnet electric drum body 1 are expanded by combining the upper roller 31 with the lower roller 32, and the permanent magnet electric drum body 1 is adapted to different usage requirements by selecting external expansion cylinders 3 of different sizes. The belt is located on the outside of the external expansion cylinder 3 for contact and transportation. When the anti-skid sleeve 4 located on the outside of the upper roller 31 and the lower roller 32 is worn and damaged during use, the external expansion cylinder 3 is disassembled and the anti-skid rubber bag 41 is removed from the outside of the upper roller 31 and the lower roller 32 using the connecting surface 42, and the anti-skid sleeve 4 is replaced to fit the replaced anti-skid rubber bag 41 to the outside of the upper roller 31 and the lower roller 32 using the connecting surface 42.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
