The invention discloses a miniature cash processing system, which belongs to the technical field of financial equipment and comprises a sorter, a cash bundle conveying device, a cash bundle processingsystem, a plastic packaging device and a control center for coordinating and controlling the devices. According to the invention, cash bundle sorting processing and stacking pre-wrapping are integrated, and the pre-wrapped cash bundle stacks are directly output or conveyed to a plastic packaging device, so that modular design is realized; when the cash bundle stack is pre-wrapped, any cash bundleis pre-bundled by adopting different control programs according to different numbers of cash; a multi-channel cash sorting device can achieve the purpose of sorting four cash bundles at the same time. A cash bundle position adjusting device in the multi-channel cash sorting device can adjust the position of a cash bundle before the cash bundle enters the cash receiving channel. The system ensuresthat cash bundles smoothly enter the channel, has self-adaptability, can process cash of all denominations of 1-100 yuan, can convey the cash bundles of the cash of different denominations to the stacking device, achieves mixed stacking of the stacking device, and completes pre-wrapping of a specified amount of cash.

The invention discloses a mounting structure of an automobile carbon tank. The mounting structure comprises the carbon tank and a mounting support. Guide grooves are formed in the edges of the two sides of the front face of a support body of the mounting support, the distance between the guide grooves in the two sides becomes narrow gradually from top to bottom, two guide rails in corresponding fit with the guide grooves of the mounting support are arranged on the outer wall of the carbon tank, the distance between the two guide rails becomes narrow gradually from top to bottom, each guide rail is divided into two sections longitudinally, and the carbon tank and the guide grooves support body are clamped and fixed through the guide rails. The mounting structure can stably and reliably fix the carbon tank, the carbon tank can be conveniently mounted and dismounted, and the requirement for mounting and dismounting operation space is low.

The invention provides a three-phase five-column type amorphous alloy transformer. The three-phase five-column type amorphous alloy transformer comprises an amorphous alloy, a coil, a clip, a transformer frame and a transformer tank, wherein the clip is divided into an upper clip, a lower clip and a side clip; the transformer further comprises a noise reducing device; the noise reducing device comprises a strengthening bar and a shock-absorbing device; the shock-absorbing device is divided into a first shock-absorbing device and a second shock-absorbing device; the second shock-absorbing device comprises a lower fixing plate and lower shock absorbers; the lower fixing plate is connected with the transformer tank via the lower shock absorbers; a shock-absorbing cavity is disposed on the lower fixing plate; the lower shock absorbers are disposed inside the shock-absorbing cavity; the number (N) of the the lower shock absorbers at the bottom of the lower clip is no less than three; the central location of the bottom of the transformer frame is provided with the lower shock absorber all the time; and the rest of the shock absorbers are centrally symmetric in distribution with respect to the central shock absorber. According to the transformer provided by the invention, the shock passing between the amorphous alloy and the transformer tank is reduced to the maximum by adopting multiple shock absorption, and the anti-shock performance of the noise-reducing device is effectively improved; and the assembling of the shock absorbing device is simple and easy.

The invention discloses a rack for communication equipment, relates to the technical field of racks for communication equipment, comprising a first main body frame and a second main body frame, the inner bottom end of the first main body frame and the inner top end of the second main body frame All have the first chute. The sliding support bar of the present invention can slide from the first chute to the second chute, and then four sets of sliding support bars support and fix multiple sets of turning arms to form the main frame of the communication device, and then the four sets of first folding arms Turn over 90 degrees so that the end of the first folding arm just fits into the inside of the sliding support rod, and then turn the two sets of second folding arms inside each set of first folding arms to the outside at 90 degrees, and then every two sets of folding arms The second folding arm forms a placement area for communication equipment. The whole of the present invention does not need to be fixed by screws or welded when it is installed and unfolded, and when the whole of the present invention is folded, the space occupied by the whole is greatly reduced, which is convenient for transportation and after folding secondary transport.

The invention discloses a plastic circular loom, and belongs to the field of plastic weaving machinery, which solves the problem that dust is easy to accumulate on the lower surface of an upper door ring and the upper surface of a lower door ring in the prior art.
