The utility model provides a carton cutting workbench convenient to clean, and relates to the technical field of carton processing, the carton cutting workbench convenient to clean comprises a workbench box body, supporting plates are fixedly installed at the two ends of the two surfaces of a through groove, a moving assembly is arranged in an inner cavity of the workbench box body, and fixing assemblies are arranged at the tops of the two sides of the workbench box body. The tops of the two supporting plates are fixedly connected with a portal frame. Two first connecting columns are supported through four extending connecting blocks, a portal frame is supported through two supporting plates, two workbench panels are connected through the two first connecting columns, opening and closing of the two workbench panels are controlled through a moving assembly, and therefore paper boards on the surfaces of the workbench panels can be conveniently cut into strips and chippings. A paperboard is supported through the two workbench panels, and the paperboard is fixed through the fixing assemblies. The air cylinder and the cutting knife are supported through the portal frame.

This invention discloses a channel equalization method for an SC-IFDMA system, comprising the following steps: transforming the received data of the SC-IFDMA system to the frequency domain; obtaining pilot symbols and data symbols according to the system frame structure; estimating the current signal-to-noise ratio (SNR) and current channel characteristics based on the pilot symbols to obtain estimated SNR and channel estimation parameters; calculating channel equalizer coefficients based on the estimated SNR and channel estimation parameters; passing the data symbols through the channel equalizer, setting the number of iterations, and iteratively equalizing the data symbols using the channel equalizer coefficients; transforming the equalized data symbols to the time domain and making a decision; determining whether the current number of iterations is the set number; if the set number is reached, outputting the current data symbol as the final iterative equalization result. The method disclosed in this invention improves equalization performance while keeping most of the processing in the frequency domain, reducing the complexity of signal processing.

The invention relates to the technical field of EPS foam boards, and discloses an automatic water removal device for unloading an EPS foam board forming machine, comprising a forming device, a transport device is arranged at the bottom of the forming device, an operating table is arranged at the bottom of the transport device, and a laser cutting device is arranged on the top of the operating table; the automatic water removal device for unloading the EPS foam board forming machine, through the coordinated use of a fixed frame, a fixed plate, a telescopic rod and a clamping plate, when the machine is turned on, the rotation of the rotating shaft can make the foam board transported forward to a front position, and a gravity sensor is arranged inside the roller on the side farthest from the transport device, and the gravity sensor is electrically connected to the telescopic rod. When the foam board is transported forward to contact with the roller, the gravity sensor senses the change in gravity and can control the telescopic rod to stretch, so that the clamping plate contacts the two side surfaces of the foam board, thereby achieving the effect of fixing the foam board.

This application discloses a molecular sieve pelletizing machine, relating to the field of pelletizing machines. The present invention provides a molecular sieve pelletizing machine, relating to the technical field of pelletizing machines. The molecular sieve pelletizing machine includes a base, a support frame on top of the base, and a rotating box rotatably connected to one side of the support frame. A rotary motor is located on one side of the support frame. In this application, raw materials are first added to the interior of the rotating box through a feeding port. Then, the rotary motor is started to rotate the rotating box. Next, a water pump box is started, causing water in the water pump box to be sprayed into the rotating box from a spray nozzle on a water spray pipe connected to the water pump box. A baffle is provided to prevent raw material powder agitated by the water spray from the spray nozzle, thus preventing this raw material powder from splashing everywhere and affecting the working environment. A cleaning device can be used to clean the bottom surface of the baffle and the inner wall of the rotating box to remove the wet raw material powder adhering to them, preventing wet powder residue from sticking to the inner wall of the rotating box and the bottom surface of the baffle and being difficult to clean.
