Abstract

Technical Field
[0001] The utility model relates to the field of lasting machines, in particular to an electric grinding system of lasting machines. Background Art
[0002] The upper of injection molded shoes is generally first formed on the upper mold, and then the upper mold and the upper are put into the injection molding machine together to injection mold the sole so that the sole and the upper are firmly bonded together. Since a lot of labor is reduced in the production process, the price is affordable, and since no glue is used in the sole molding process, the harm of glue to the human body can be avoided.
[0003] In order to achieve semi-automatic or even automated production, multiple sets of sole mold clamping mechanisms and shoe lasts can be set on a rotating platform, and each clamping mechanism and shoe last are evenly distributed around the rotating platform. However, since each clamping mechanism, shoe last lifting mechanism, etc. require electricity, if the traditional circuit structure of pulling wires is used, as the rotating platform rotates, the wires will become entangled, causing the lines to age quickly or even break, and the maintenance cost is high. Utility Model Content
[0004] The utility model aims to provide an electric grinding system for a lasting machine, which can effectively prevent the line from breaking due to winding and ensure the normal power supply of the equipment.

[0006] As a further improvement of the utility model, the conductive ring is provided with a first terminal, and the conductive brush assembly is provided with a second terminal.
[0007] As a further improvement of the utility model, the fixed bracket includes connected end fixing rings and multiple first insulating connecting rods, the conductive rings are spaced apart from each other and connected to the first insulating connecting rods, a first insulating sleeve is provided between adjacent conductive rings, and the first insulating sleeve is provided on the first insulating connecting rod.
[0008] As a further improvement of the present invention, the rotating bracket includes an end rotating ring and a second insulating connecting rod connected to each other, and the conductive brush assembly is arranged on the second insulating connecting rod.
[0009] As a further improvement of the utility model, at least two conductive brush assemblies are arranged on the same second insulating connecting rod, a second insulating sleeve is arranged between adjacent conductive brush assemblies, and the second insulating sleeve is sleeved on the second insulating connecting rod.

[0011] As a further improvement of the present invention, the conductive ring is a copper ring.
[0012] Beneficial Effects
[0013] Compared with the prior art, the advantages of the grinding system of the lasting machine of the utility model are:
[0014] 1. When the rotating bracket rotates around the fixed bracket, the conductive brush assembly is always in contact with the conductive ring, ensuring that the conductive brush assembly and the conductive ring are always electrically connected. Since this part does not use wires, the problem of wire entanglement caused by rotation can be avoided. The power supply is electrically connected to the conductive ring through the wires, and the conductive brush assembly is electrically connected to the corresponding electrical equipment through the wires.
[0015] 2. The conductive rings are spaced apart from each other and connected to the first insulating connecting rod, which can ensure that the multiple conductive rings are installed firmly.

[0016] 3. At least two conductive brush assemblies are arranged on the same second insulating connecting rod. The number of conductive brush assemblies can be increased without increasing the number of second insulating connecting rods, thus avoiding an increase in floor space.
[0017] 4. In the conductive brush assembly, the spring is pre-stretched, and the contraction trend of the spring keeps the carbon brush close to the conductive ring to avoid poor contact.
