7results about How to "Improve stacking effect" patented technology

This utility model belongs to the field of towel production technology and discloses an automatic towel stacking device, including a worktable. The top of the worktable has an inverted U-shaped groove. A pair of first sliders are symmetrically installed on both sides of the inverted U-shaped groove. A base plate is installed on the top of the opposite side of the pair of first sliders. A pair of first guide rods are symmetrically installed on the top of the pair of first sliders. A pressing plate is slidably installed between the pair of first guide rods. A first mounting plate is installed on the top of the pair of first guide rods. An electric telescopic rod is installed on the top of the first mounting plate. This device, through the fixing of the pressing plate and the base plate and the movement of the first sliders, pulls the towels onto the surface of the placement table for stacking. During the movement, protrusions help to flatten the towels. Simultaneously, the towels can be quickly removed after stacking, thereby reducing the labor cost of towel stacking and improving the work efficiency and stacking effect.

The utility model discloses a portable municipal sewage wellhead warning indicator which comprises a main supporting rod and an auxiliary supporting rod, the main supporting rod and the auxiliary supporting rod are rotationally connected through a stand column base, a stand column is arranged at one end of the stand column base through an adjusting fastening assembly, and a warning lamp is arranged on one side of the top end of the stand column.

According to the warning indicator, the portability can be improved to the maximum extent through the folding design, the stacking performance is excellent after the whole structure is stored, the integrality is high, the weight is light, the warning capacity is high, and therefore operation and maintenance teams can rapidly deploy a large number of devices.

The utility model relates to the technical field of bread processing equipment, and discloses a stackable baking tray, which comprises a baking tray main body and an edge tray, an oil discharge groove is arranged at the edge position in the baking tray main body, a concave circular groove is arranged on the top surface of the edge tray, a positioning column is fixed at the bottom of the edge tray, and the positioning column is fixed at the bottom of the edge tray. The circular groove and the positioning column are located on the same vertical face, and the outer side wall of the baking tray body and the outer side wall of the edge tray are coated with Teflon coatings. The round grooves are formed in the top of the edge disc, the round grooves are circularly distributed into four groups, the positioning columns are fixed to the bottom face of the edge disc, the round grooves and the positioning columns are also circularly distributed into four groups, at the moment, the round grooves and the positioning columns are located on the same vertical face, and one positioning column falls into one round groove; and the four positioning columns fall into the circular grooves, so that the four positioning columns can be stacked upwards in sequence after being positioned, the purpose of facilitating stacking is achieved, the stability after stacking is improved, and therefore the stacking effect is well improved in the working process.

The invention pertains to a sheet-like composite (100), comprising: a. a carrier layer (103), b. a barrier layer (105), c. an inner polymer layer F (108), and d. an inner polymer layer H (109); wherein the barrier layer (105) comprises - a barrier material layer (106), and - a barrier substrate layer (107) comprising a polyolefin; characterised in that the inner polymer layer F (108) comprises at least 40 wt.-% of a mPE, based in each case on the total weight of the inner polymer layer F (108). The invention further pertains to methods (300, 600, 700) for producing a sheet-like composite (100), a container precursor (400), and a closed container (500), to a container precursor (400), a closed container (500), and uses of the sheet-like composite (100), of a mPE, of a LDPE and of a combination of a mPE and a LDPE.

This invention discloses an amino compound with a benzophenanthrene furan group and an organic light-emitting device, selected from compounds of formula 1: Al-A 10 One of the groups is derived from Formula 2, where * represents a bond connected to the basic skeleton in Formula 1. When A2 is derived from a group in Formula 2, L1 is a para-phenylene group, R1 and R2 are derived from single bonds, substituted or unsubstituted C5-C24 aromatic hydrocarbon groups, substituted or unsubstituted C5-C24 heteroaromatic hydrocarbon groups, and Ar1 and Ar2 are derived from C5-C30 aromatic hydrocarbon groups, substituted or unsubstituted C5-C30 heteroaromatic hydrocarbon groups. In this invention, the triarylamine is para-linked to a transition benzene ring with benzo[a]phenanthrenefuran. This benzene ring linkage enhances the overall stability of the target molecule, strengthens the conjugation of the molecule, and increases the stacking property of the molecule in organic light-emitting materials. This invention also sets phenanthrene, naphthyl, or dibenzothiophene groups on the other two substituents of the triarylamine, affecting the electron affinity and electron transport properties of the triarylamine and further extending its lifespan.

The application relates to a coal mine plugging gelatinizing agent and a preparation method thereof, and relates to the technical field of coal mine plugging materials. The coal mine plugging gelatinizing agent comprises the following components in parts by weight: modified bentonite 60-75 parts, calcium chloride 10-25 parts, a filler 1-10 parts and cellulose 0.5-5 parts. The modified bentonite is obtained by mixing and magnetizing modification of bentonite and sodium silicate; and the filler is composed of spherical aluminum powder and hydrotalcite powder. The modified bentonite prepared by mixing and magnetizing modification of bentonite and sodium silicate is used as the main component, so that the compressive strength of the gelatinizing system is improved, and the overall adhesion is strengthened; in combination with the filler composed of spherical aluminum powder and hydrotalcite powder, calcium chloride and cellulose, the viscoelasticity, compactness and piling property of the mud can be effectively improved, so that the problems of poor compressive strength and poor air plugging effect of the existing inorganic plugging gelatinizing agent are effectively solved.
