A tamper-evident container generally includes a tray having an opening with a step section formed around the opening and including a first protrusion section that is provided with a first coupling unit with a first perforation line formed therebetween. The first coupling unit includes a coupling trough. A cover includes a concave groove having a bottom and an outside surface engageable with the step section to close the opening. The cover includes a second protrusion section and a second coupling unit between which a second perforation line is formed and projecting beyond the first perforation line. The second coupling unit has a coupling member receivable in and engageable with the coupling trough. Tearing off the first and second perforation lines allows the first and second coupling units to detach from the tray and the cover, respectively with the second protrusion section projecting outside the tray for easy gripping.

The invention discloses a sucking-upward and turning-downward cake demolding device. The device includes a support, a conveyor line unit, a turning-downward unit, an adsorption unit and a moving unit;the conveyor line unit is arranged on the lower side of the support, and can perform continuous conveying on formed cakes; the turning-downward unit is arranged on one side of the conveyor line unitand on the support, and can turn over the conveyed cakes to make the cakes fall on a cooling tray on the lower side through an overturn motion; the adsorption unit is arranged above the conveyor lineunit, and can adsorb the cakes on the conveyor line unit to the turning-downward unit by moving horizontally and up and down; and the moving unit is arranged on the upper side of the support, and canhorizontally move along the support and drive the adsorption unit to move horizontally and up and down. Through the arrangement of the moving unit, the adsorption unit and the turning-downward unit from top to bottom, the cakes can be turned over so that cake crusts can be on the top side after the cakes are formed, and appearance damages to the cake crusts caused by the contact with carries can be avoided.

The invention discloses a particle feed grease spraying machine in the field of feed production, which includes a base, an atomizer is fixedly connected to the upper surface of the base, a connecting pipe is fixedly connected to one side of the atomizer, and a single pipe is arranged on the outer surface of the connecting pipe. The top of the base is fixedly connected with a support frame, the top of the support frame is fixedly connected with a spraying box, the top of the spraying box is fixedly connected with an air intake pipe, the inner top wall of the spraying box is fixedly connected with a mounting seat, and the bottom of the mounting seat is fixedly connected There is a sleeve, the inner wall of the sleeve is plugged with a moving rod, the bottom of the moving rod is fixedly connected with a piston, the top of the support frame is fixedly connected with an air pump, and the output end of the air pump is fixedly connected with a connecting air pipe; in the present invention, by setting the atomization Machine, connecting pipe, one-way valve, spraying box, air intake pipe, sleeve, moving rod, piston, air pump and connecting air pipe. This design ensures the complete shape of the feed while injecting animal and vegetable oil into the pellet feed, avoiding Contour breakage during grease application.

The invention discloses an easy-pulled bottle cap pull ring riveting edges gapless cutting and molding method. A pull ring comprises an annular pull handle portion and a riveting portion connected with the inner side of the annular pull handle portion and used for riveting and being matched with a bottle cap. A specific molding method comprises the steps that a pull ring blank plate of which a contour is cut of the edges and molded is disposed between an upper die and a lower die of a stamping die, and the edges of the contour trimming edge of the pull ring blank plate are folded through declining and stamping of the lower die; the upper die cooperates with the lower die, a transition between a profiling inner depression of the annular pull handle portion, the lower end edge of the profiling inner depression of the riveting portion and an upper die main body is an arc-shaped chamfering transition, and the transition between a profiling protrusion of the annular pull handle portion, theupper end face edge of the profiling protrusion of the riveting portion and a lower die main body is an arc-shaped chamfering transition, so that when the upper die and the lower die cooperate with each other, the dies are not prone to be scraped and noticeable scratch marks are not prone to be left on the surface of the contour trimming edge of the pull ring blank plate.

Dust collection structure for collecting the dust removed from an air filter of an indoor unit has been devised to reduce user's labor in collecting the dust as much as possible. An indoor unit (13) includes, in a casing (34), an indoor heat exchanger (37), an indoor fan (39) for sucking air from inside of a room, and blowing the air to the inside of the room, and an air filter (40) arranged on an inlet side of the indoor fan (39). The dust trapped on the air filter (40) is removed by the dust removing means (50), and is contained in the dust containing part (60). A nozzle connector (78) for arranging a nozzle (95a) of a cleaner (95) at a predetermined position where suction of the contained dust is allowed is provided at a downstream outlet of a dust collection path (77) as a transfer path for transferring the dust in collecting the contained dust.

A visual vacuum carrier is characterized a carrier plate serves as a body, a plurality of metal weights arranged at equal intervals are fixed to the front of the carrier plate, the center of each metal weight is provided with a vacuum hole penetrating the carrier plate, the metal weights are used for attracting a part to be carried, the surfaces of the metal weights match with the bottom of the part to be carried, the four edges of the back of the carrier plate are cut edges, the carrier plate is provided with a plurality of elongated vacuum slots in the horizontal direction, each elongated vacuum slot accommodates one vacuum hole arranged horizontally, a bottom tray is tightly connected with the back of the carrier plate through the cut edges, and the face, in contact with the elongated vacuum slots, of the bottom tray is provided with vacuum entries. The visual vacuum carrier is good in fixing effect, high in precision and effective in preventing the part to be carried, from appearance loss and material loss.

The invention discloses a manufacture method of a light-cured composite resin film, comprising the following steps of: (1) providing a plastic substrate, light-cured composite resin, a printing ink layer and plastic, wherein the plastic substrate is provided with an upper surface and a lower surface; (2) coating the upper surface of the plastic substrate with the light-cured composite resin; (3) impressing and solidifying the light-cured composite resin to form a plurality of patterns; (4) forming the plastic substrate and the plurality of patterns; (5) coating the printing ink layer on the lower surface of the plastic substrate; and (6) ejecting and attaching the plastic on the printing ink layer.

The invention relates to a manufacturing process of a soft printed circuit board with different appearances at upper and lower layers, which is used for manufacturing a first stack and a second stack of the soft printed circuit board with different appearances at upper and lower layers. The manufacturing process comprises the following steps of: (1) adding an auxiliary layer between the first stack and the second stack, wherein the auxiliary layer is provided with hollow dodging areas in identical-appearance areas of the first stack and the second stack; (2) after the first stack and the second stack having duplicate layers are manufactured based on a general flow, unfolding edge area cavities of the identical-appearance areas of the first stack and the second stack; (3) die cutting the first stack and the second stack according to the appearances of the first stack and the second stack respectively; and (4) drawing out the auxiliary layer to obtain the soft printed circuit board withdifferent appearances at upper and lower layers. Since the auxiliary layer is added between the stacks with different appearances in the invention, appearance damage caused by mutual interference of the appearances is avoided, and soft circuit boards with different appearances are integrated together to reduce the cost and assembly space of adapting parts.
