The invention relates to an electrical cabinet. The electrical cabinet comprises a main cabinet body and a cabinet door, wherein the cabinet door is installed at the front portion of the main cabinet body, the rear side of the main cabinet body is provided with a through hole; the through hole is provided with a radiator, the radiator comprises a heat dissipation vent and an air inlet, the heat dissipation vent and the air inlet are internally provided with filter screens, the bottom of the main cabinet body is provided with multiple rolling wheels, the rolling wheels are provided with brakes, and the left side and the right side of the main cabinet body are provided with insulating handles. According to the invention, the rear side of the main cabinet body is provided with the radiator so that the heat dissipation problem of the electrical cabinet can be well solved; at the same time, the bottom of the main cabinet body is provided with the rolling wheels so that the moving of the electrical cabinet is facilitated; the rolling wheels are provided with the brakes so that when the electrical cabinet need not to be moved, the rolling wheels are clamped and prevented from moving; and the left side and the right side of the main cabinet body are provided with the insulating handles so that the electrical cabinet can be safely and conveniently moved.

The invention provides a closed three-roll air cushion conveyer. According to the closed three-roll air cushion conveyer, a charge port is arranged in one side of a shell, and a discharge port is arranged in the other side of the shell; a drive roller is arranged in the shell at one side of the discharge port; a driven roller is arranged in the shell at one side of the charge port; the drive roller is connected with the driven roller through a belt; an air inlet port is arranged in the shell; a plurality of inclined carrier rolls and horizontal carrier rolls are arranged on the shell along an advance direction of the belt; each two paired inclined carrier roll and horizontal carrier roll are arranged in a staggered manner; an air chamber is arranged in a bottom plate of the shell; the air chamber is arranged along a length direction of the shell; the air inlet port communicates with the air chamber through a pipeline; air outlet holes are arranged in the bottom plate of the shell; and the air outlet holes are corresponding to the bottom surface of the belt. According to the closed three-roll air cushion conveyer provided by the invention, an air blowing device is arranged at the bottom of the airtight shell, the return belt is blown through the air blowing device during return of the conveyer belt, and an air cushion is formed between the return conveyer belt and the inner bottom surface of the shell, thus friction between the return conveyer belt and the inner bottom surface of the shell is prevented, the service life of the belt is ensured, and the energy consumption of the conveyer is reduced.

The invention relates to an open mill roller rubber block plate device. The open mill roller rubber block plate device comprises a rack and a first rubber block plate, a second rubber block plate, a third rubber block plate and a fourth rubber block plate which form a feeding port, wherein the third rubber block plate and the fourth rubber block plate are fixedly arranged on the rack radially, the first rubber block plate and the second rubber block plate are arranged axially, the two ends of the upper portion of the first rubber block plate and the two ends of the upper portion of the second rubber block plate are fixedly provided with rotating shafts respectively, and the rotating shafts are arranged on the rack in a hinged mode; the two sides of the lower portions of the first rubber block plate and the two sides of the lower portions of the second rubber block plate are provided with locking devices respectively, and each locking device comprises a machine base, an air cylinder, a first locking wedge block and a second wedge block, wherein the machine base is fixedly arranged on the rack, the air cylinder is fixedly arranged on the machine base, the first locking wedge blocks are fixedly arranged at the lower portions of the first rubber block plate and the second rubber block plate, the inclined plane of the first locking wedge block is opposite to the inclined plane of the second locking wedge block, and the other plane of the second locking wedge block is connected with a piston rod of the air cylinder. According to the open mill roller rubber block plate device, an open mill is of a fully-enclosed structure, and therefore rubber materials inside are kept in.
