The invention discloses a western-style clothes front shirt and liner molding die and a manufacturing method thereof. The western-style clothes front shirt and liner molding die comprises a first template, a clamping plate and a second template; the first template, the clamping plate and the second template are successively superposed and form turnover movable connection at one end, and needle walking grooves are formed in the first template, the clamping plate and the second template; the portions between the clamping plate and the first and second templates are respectively used for clampinga liner and a front shirt; a first protrusion, a second protrusion, a third protrusion and a fourth protrusion are arranged on the clamping plate along the needle walking grooves; the first protrusion is used for increasing remaining amount of a lapel corner of the liner; the second protrusion is used for increasing folding amount of a fold line of a lapel; the third protrusion is used for increasing loose amount of a lapel seam allowance end; the fourth protrusion is used for making a lower hem of the front shirt be concave after molding of the lower hem of the front shirt. Smoothness of theprepared western-style clothes front shirt and liner is better, the close-fitting characteristic of the lower hem of the front shirt and lapel is better, the lapel at the lapel corner position and the lapel fold line position is more close-fitting and cannot easily upwarp, the operation is simple, the production efficiency is higher, and the consistence of product quality is better.

The invention relates to a drying treatment device for feed production and processing, which includes a drying mechanism and an air drying mechanism. The air drying mechanism is installed directly below the drying mechanism, and the lower end of the air drying mechanism is installed on the existing working ground. The invention adopts the design concept of double drying structure and phase structure to carry out the drying treatment of feed production and processing. The set drying machine and air drying mechanism can adopt two drying modes for the feed, and the drying effect of the feed increases step by step. The method of blowing hot air and drying the feed adopted by the drying mechanism can make the feed receive a more comprehensive drying treatment in a loose state, so that the drying speed and drying molding quality of the feed can be greatly improved.

The invention relates to the technical field of fiber preparation and production, in particular to a drying treatment machine for the preparation of regenerated protein cellulose fibers, including a drying box, a limit block, a pulling device, a driving motor, a barrier device and an air intake device. The drying box It has a rectangular structure, and the inner wall of the drying box is symmetrically installed with a limit block up and down near the left end, and a pulling device is arranged on the right side of the limit block. The invention can solve the problem that the existing machinery usually directly dries the fiber by hot air when drying the regenerated protein cellulose fiber, but the hot air cannot directly dry the inner fiber, thereby reducing the fiber drying rate and the like. The pulling device used in the drying treatment machine for the preparation of regenerated protein cellulose fibers provided by the present invention can pull the fibers up and down, thereby increasing the gap between the fibers, allowing the inside and outside of the fibers to be dried quickly at the same time, improving the The rate at which fibers are dried.

The invention provides a system device for directly and effectively spray-drying high-solid-content sludge, which comprises a hopper, wherein the hopper is connected with a feed pump and used for feed agitation, the feed pump is connected with one end of a nozzle in a spray drying tower through a pipeline, and the other end of the nozzle is connected with an air compressor; an air inlet at the lower part of the spray drying tower is connected with a hot blast furnace through the pipeline, the top of the spray drying tower is connected with a dust remover through the pipeline, the dust removeris connected with a smoke gas wet recovery tower through the pipeline provided with an exhaust fan, and the recovery tower is communicated with a pool arranged at the bottom of the recovery tower anda nozzle at the top through the pipeline provided with a water pump. The invention also provides a method adopting the system device for directly and effectively spray-drying the high-solid-content sludge. The invention has the effects that the energy consumption is low by using the method, and the atomized sludge has small grains, uniform diameter, good drying effect, high loosening degree and high porosity and is markedly superior to other drying forms. The produced drying sludge is adaptable to the paths of combustion heating, cement manufacture, greening, landfill and the like.

The invention discloses a plate-belt composite bulk material ship loader, which comprises a bed frame, a transport plate frame and a long block. The transport plate frame is installed on the top of the bed frame, and the front and rear inner walls of the transport plate frame are installed with A long block, the outer wall of one side of the bed frame is equipped with a main frame, and the top of the main body frame is equipped with a column; the top of the column is equipped with a conveying structure, and the inside of the conveying structure is equipped with a conveying frame. An extension frame is installed on the bottom of the delivery frame, fixing plates are installed on both sides of the delivery frame, and connecting plates are installed on both sides of the extension frame. When the present invention is in use, its feeding pipe can be adjusted to the center position of the hull, and the hull can avoid rollover during the material discharge process. At the same time, when the feeding pipe is blocked, two ways of squeezing and rotating can be used to dredge the pipeline. The device can screen materials during feeding to avoid larger block materials from entering the device, which will cause blockage of the feeding pipe in the later stage.
