The utility model discloses a device for quickly pasting a marine antifouling coating, which comprises a moving trolley, the cloth roll frame, the rubber wheel and the compaction wheel are sequentially arranged on the moving trolley; the cloth roll frame is used for erecting a sticking type antifouling coating; the rubber wheel is used for brushing an adhesive to the bottom of the sticking type antifouling coating; the compaction wheel is used for compacting and sticking the glued sticking type antifouling coating to a to-be-stuck surface; when the movable trolley moves forwards, the adhesive type antifouling coating on the cloth roll frame along with the trolley is pulled out, the upper side of the rubber wheel drives the rubber wheel to roll and brush glue, and then the compaction wheel is driven to roll and compact the surface to be adhered through friction of the non-glued surface of the adhesive type antifouling coating below the compaction wheel. According to the utility model, the construction efficiency of the adhesive antifouling coating can be improved.

The utility model relates to the technical field of paint surface detection, in particular to a friction roller and a friction assembly structure for a paint surface wear experiment. The friction roller for the paint surface wear experiment comprises a friction belt and a roller core, the roller core is of a cylindrical structure and forms a rotating center of the friction roller; a friction belt is fixed and wound on the roller core, and the wound friction belt and the roller core form a cylindrical structure with a friction layer on the side face to form the friction roller. When detection is needed, the friction roller is driven to rotate stably, the friction layer on the side wall of the friction roller is made to make contact with the paint surface sample, the rotating direction of the friction belt is made to be consistent with the winding direction, and the rotating friction roller rubs the paint surface sample. A uniform friction trace is formed by moving a sample, and then detection and evaluation are performed. When the side face of the friction roller is abraded, a paint surface sample cannot be accurately evaluated, and the abraded friction belt can be uncovered and torn off, so that the service life of the friction roller can be prolonged, and the experiment cost is reduced.

This invention provides a method for controlling constant tension on a wrapping reel and a wrapping reel with a constant tension control mechanism. The constant tension is controlled using a mechanical structure, which is simple and ingenious, requiring no complex electrical control components. When the wrapping reel is fully loaded with insulating tape, a cam lifts the adjusting rod. As the wrapping progresses, the diameter of the reel gradually decreases, and the pressure roller moves closer to the inside of the reel, causing a swing arm to oscillate. The cam at the other end of the swing arm rotates with the swing arm, causing the adjusting rod to rotate as well. Because the adjusting rod rotates eccentrically, and the longer side of the adjusting rod is closer to the friction wheel, the friction tape is loosened with a larger vertical displacement; the shorter side of the adjusting rod is farther from the friction wheel, tightening the friction tape with a smaller vertical displacement. Overall, the friction tape is loosened, thus reducing the clamping friction torque. This achieves constant tension as the wrapping reel gradually reduces the amount of tape being wrapped.

The invention discloses a length-adjustable operating grab handle and a using method, the length-adjustable operating grab handle comprises a plurality of sleeves (1) which are arranged in an inner and outer nesting mode, a mounting cavity (2) is formed between every two adjacent sleeves (1), a limiting assembly is arranged in each mounting cavity (2), and the outer portions of the limiting assemblies are connected with the two sleeves (1) respectively and used for enabling the two sleeves (1) to be in mutual friction limiting; the limiting assembly comprises a first friction belt (3) and a second friction belt (4), the first friction belt (3) is located on the inner wall, on the outer side of the mounting cavity (2), of the sleeve (1), the second friction belt (4) is located on the outer wall, on the inner side of the mounting cavity (2), of the sleeve (1), and the first friction belt (3) and the second friction belt (4) are staggered in the circumferential direction of the sleeve (1). The telescopic clothes hanger has the advantages of being capable of freely stretching out and drawing back and convenient to carry.

The utility model relates to precoat film technical field, specifically disclose a kind of precoat film daubing roller's rubber baffle, including support, the middle part of support is connected with daubing roller, the middle part of support is connected with press roll below daubing roller, the middle part of support is connected with two-way screw rod, the sidewall of daubing roller is connected with rubber baffle, the middle part of rubber baffle is connected and is arranged with limited ring groove, the middle part of limited ring groove is connected with rotating ring, the sidewall of rotating ring is provided with inlay ring, and the sidewall of inlay ring is connected with ball. Rotating ring can be let daubing roller rotate when being arranged in the device, will friction drive rotating ring to rotate, avoid daubing roller when rotating and rubber baffle not rotating, cause abrasion to the middle part inner wall of rubber baffle, to produce gap and let adhesive leak. Solve the problem that plastic film is pre-coated when passing through daubing roller, daubing roller will rub the rubber baffle of both sides when rotating, cause rubber baffle abrasion to produce gap, and let adhesive leak.

The utility model discloses an electric take-up and pay-off crosspiece cloth winding device, and belongs to the technical field of crosspiece cloth winding. The device comprises a platform, a motor is installed at the top end of the platform, a winding drum is rotatably installed on the side wall of the platform, blocking cloth is wound on the side wall of the winding drum, a fixing assembly is fixedly installed on the side wall of the platform, sweeping assemblies are symmetrically installed in the fixing assembly, and a protection assembly is installed on the side wall of the fixing assembly.
