The invention discloses an automatic spring puncture needle sampling structure. The automatic spring puncture needle sampling structure comprises an upper guide sleeve, a lower guide sleeve, an automatic spring, a needle fixing base and a puncture needle; the lower guide sleeve is in sliding and sleeving connection with the lower end of the upper guide sleeve; the lower end of the needle fixing base is fixedly connected with the upper end of the upper guide sleeve in a sleeving way; the automatic spring is arranged in the upper guide sleeve; the upper end of the automatic spring is connected with the needle fixing base and the lower end of the automatic spring is connected with the lower guide sleeve; the puncture needle is arranged in the upper guide sleeve; the upper end of the punctureneedle penetrates through and is fixed in the needle fixing base; and the lower end of the puncture needle penetrates through the lower guide sleeve. The automatic spring puncture needle sampling structure is suitable for sampling of sealed sample bottles with different height, realizes high-precision sampling and is low in manufacturing cost.

The invention relates to a wheel sticking prevention SBS modified emulsified asphalt used for tack coat. The wheel sticking prevention SBS modified emulsified asphalt is prepared from, by weight, 100-120 parts of asphalt, 1-3 parts of furfural extract oil, 3-5 parts of an SBS high-molecular polymer modifier, 0.3-0.5 parts of a quick-cracking and quick-setting emulsifier, 0.1 parts of an emulsified asphalt stabilizer, 2-5 parts of an organosilicone resin interface reinforcing agent and 100 parts of water. The SBS high-molecular polymer modifier, the quick-cracking and quick-setting emulsifier and the organosilicone resin interface reinforcing agent added to the wheel sticking prevention modified emulsified asphalt commonly improve the pavement performance and the construction performance of the modified emulsified asphalt used for tack coat, make the modified emulsified asphalt be suitable for being used in roads, and can prolong the service life of the roads.

The invention provides a multi-stroke dustproof pulse cloth bag type dust removal device which comprises a supporting base, a sleeve and a stroke plate. The top of the supporting base is fixedly connected to the bottom of the whole dust removal device through bolts. A dust storage box in an inverted isosceles trapezoid shape is welded to the bottom of a dust removal box. Due to an air inlet flow guide plate and an exhaust end guide plate, after air flow with dust enters the dust removal box, the mixed air flow can move up under the guide effect of the air inlet flow guide plate, and dust accumulated in the dust storage box on the lower side can be protected and is prevented from being brought away by the air flow again; due to the exhaust end guide plate, when the mixed air flow reaches the side wall of the right end of the dust removal box and enters a gentle state, the air can be guided to flow upward with the aid of the exhaust end guide plate, and the dust can fall downward into the dust storage box under the gravity effect.

The invention provides a metal packaging structure and preparation method, a packaging method of a display panel, and a display device, and relates to the field of display technology, which can significantly improve the adhesion between the metal film and the adhesive layer, and avoid the need to protect the protective film on the surface of the adhesive layer. The adhesive film is lifted up during peeling to reduce production costs and improve production yield. The preparation method includes: providing a metal film, the metal film has an opposite first surface and a second surface; forming a silane film on the first surface; the surface of the silane film far away from the metal film has active groups a group; attaching the first surface formed with the silane film to the adhesive layer, so that the active groups react with the adhesive layer to combine.

The invention discloses a tearable cleaning-free plastic baffle. A plurality of layers of tearable films are overlaid on a base plate. The side edges of the tearable films are provided with tear strips used for tearing the tearable films away from the base plate. The tear strips on the tearable films are sequentially arranged in a staggered manner along the side edge from top to bottom. The side edge, on the same side with the tear strips, of the base plate is provided with a protective device used for holding the tear strips. One side of the protective device is open, wherein the tear strips can be placed in the protective device through the open side. The opening faces the base plate. Partition plates are arranged in the protective device and used for separating the tear strips. Broken lines capable of being snapped are arranged at the intersection position between the partition plates and the upper surface of the protective device. The tearable cleaning-free plastic baffle has the advantages of being convenient to use and avoiding misalignment after tearing.

The invention discloses a blood collection tube rotating and compressing device. The blood collection tube rotating and compressing device comprises a driving mechanism, a pushing plate, a first sliding block, a second sliding block, a rotating mechanism, a compressing mechanism, a first elastic piece and a second elastic piece; the pushing plate moves vertically under the driving of the driving mechanism; the first sliding block and the second sliding block move vertically under the driving of the pushing plate; the rotating mechanism is used for vibrating a blood collection tube; the compressing mechanism is used for pressing the blood collection tube; the first elastic piece is used for connecting the driving mechanism and the first sliding block; the second elastic piece is used for connecting the driving mechanism and the compressing mechanism. When blood is sampled, the rotating mechanism and the compressing mechanism work under the control of the driving device; a blood sample is vibrated uniformly through the rotating mechanism; meanwhile, the blood collection tube is prevented from being pulled when a puncture needle is pulled out because of the action of the compressing mechanism. According to the blood collection tube rotating compressing device, the labour intensity caused by vibrating and compressing the blood collection tube manually is avoided; the sampling requirements of the blood collection tubes with different lengths can be met, so that a sampling process is simple and convenient, the labour intensity is reduced, and the work efficiency is improved.
