The invention is especially suitable for material selection of big-gap dewatering asphalt pavement.

The invention relates to a method in connection with a change process of a reel-up of a fibre-web machine, which method is applied when performing a change of reeling of a web (W) from a web roll (11) being completed to a new web roll for reeling the next roll around a reeling shaft (12). In the method, for fastening the surface layer/surface layers of the web roll (11) to the web roll (11) beingcompleted, at least one two-sided tape (20) is adhered from its one side to the web (W) being passed to the web roll (11) being completed or to the surface of the web roll (11) and said tape (20) is adhered from its other side to the surface of the web roll (11) being completed/to the surface of the web (W) being reeled onto the web roll (11) being completed due to the effect of a reeling nip between the reel drum (13) and the web roll (11) or a pressing-roll nip between the web roll (11) and a pressing roll (14) or due to the effect of the tightness (T) of the web.

The invention relates to the technical field of medicine pressing accessory devices, in particular to a tabletting device for producing medical drugs. The tabletting device can conveniently control the pressed dosage and take out pressed tablets to reduce the using boundedness, can improve the compactness of the pressed tablets to reduce loosening of the tablets and improve the using reliability,and comprises a working table, a group of lower dies, a group of upper dies and a lower pressing plate and further comprises a base, a group of support columns, a group of lower support rods, a groupof support springs and a group of adjusting threaded rods; a group of rotary plates are arranged at the bottom ends of the group of adjusting threaded rods separately; the tabletting device further comprises a group of upper support rods, a group of limiting rods, a group of limiting rings, a top plate, a group of positioning springs, a lower pressing threaded rod, a runner and a rotary handle; athrough hole is formed in the center of the top plate; internal threads corresponding to the group of lower pressing threaded rods are formed in the through hole; and the bottom ends of the lower pressing threaded rods are mounted through threads and penetrate through the through hole.

The invention relates to an assembly device for an intravenous needle catheter and a needle handle, which includes a frame, a catheter assembly device arranged on the frame, a needle handle discharging device and a material transfer mechanism; wherein, the needle handle discharging device includes a feeder and a needle handle. A conveying channel for conveying needle handles, the feeder has one or a group of output ports, the feeder is fixed on the frame and can transport the needle handles to the conveying port in a unified direction and in an orderly manner along the output port. On the feeding channel; the needle handle discharge device also includes a limiting device and a positioning plate; the positioning plate and the limiting device are sequentially arranged at the end of the conveying material channel, and are driven to move up and down by the driving device.

Compared with manual loading, the work efficiency is improved.

The invention relates to the technical field of agricultural plating, and discloses a seedling-raising disc for storing and transporting seedlings. The seedling-raising disc comprises a hole tray, wherein liquid holes are formed in the upper part of the outer wall of the hole tray; a pressure plate is rotably connected to the edge of the top of the hole tray; an annular cavity located outside theliquid holes is formed in the outer wall of the hole tray; a base is arranged at the bottom of the hole tray; a main magnetic block is fixedly connected to the lower part of the base; and a sliding seat is arranged in the base. Nutrition liquid is continuously conveyed into a medium by virtue of vibration of a vehicle, so that water and liquid are adequately supplied to the seedlings, and meanwhile, the problem that manual irrigation is required in a transportation process can be avoided; and besides, the irrigated nutrition liquid is atomized by virtue of a thin channel formed in the hole tray, so that the volumes of the nutrition liquid drops are reduced, the adsorption force of the nutrition liquid drops to the medium is enhanced, the dropping speed of the nutrition liquid is decreased,the contact time of the nutrition liquid and roots of the seedlings is prolonged, and sufficient nutrients are provided for growth of the seedlings.

The invention relates to a stable assembly structure of a partition assembly. The partition assembly is composed of a plurality of detachable disassembly and assembly plates which are detachably and fixedly connected. A containing cavity is formed among the multiple disassembly and assembly plates after the disassembly and assembly plates are fixed, a reinforcing plate is arranged in the containing cavity, and an anti-falling part is arranged at the end of the reinforcing plate. Anti-falling matching parts are arranged on the plurality of disassembly and assembly plates; and the reinforcing plate is arranged on the anti-falling matching parts in an elastic anti-falling manner from the outer side through the anti-falling part, so that the reinforcing plate is stably assembled in the containing cavity. Through the cooperation between the anti-falling part and the anti-falling matching parts, the assembling stability of the reinforcing plate is improved, the phenomenon of bending deformation of the reinforcing plate can be reduced, and therefore the appearance regularity of the partition assembly is improved; due to the fact that the reinforcing plates can be stably assembled, the multiple disassembly and assembly plates can be reinforced and stabilized after being assembled, the overall structural strength of the partition assembly is improved, the problems that the partition assembly is twisted and loosened after being assembled are solved, and the use experience of a user is improved.
