This utility model relates to the field of mold technology, and in particular to a continuous pipe clamp mold that avoids long and short sides. The continuous pipe clamp mold includes an upper mold assembly and a lower mold assembly. The upper mold assembly includes an upper mold base, an upper forming male, a movable forming male, a cutter, and a stripper plate. The upper forming male and the cutter are fixedly connected to the upper mold base. The movable forming male and the stripper plate are movably disposed on the upper mold base. The cutter, the movable forming male, and the upper forming male are arranged sequentially along the feeding direction. This continuous pipe clamp mold that avoids long and short sides prevents material slippage during bending, resulting in high stability in material bending and forming, high product dimensional stability, and effectively shortens the cutter length, extending the cutter's service life. It solves the technical problems of existing pipe clamp molds, such as the easy occurrence of long and short sides during forming, poor product compatibility, and easy cutter breakage and failure.

This invention discloses a method for precise tension control in the winding process of low rolling resistance tires, relating to the field of tire manufacturing technology. It aims to solve the problem of uneven rubber distribution and reduced rolling resistance caused by inaccurate tension control during the tread winding process in existing technologies. The method includes the following steps: S1, integrating a high-response sensor network into the independent tension actuator of each winding feeding unit. The high-response sensor network includes a release tension sensor, a conveying tension sensor, and a bonding tension sensor, corresponding to the three processes of rubber strip conveying, release, and bonding, respectively, to collect the instantaneous tension value of the rubber strip throughout the entire process in real time; S2, based on the material properties of the rubber strip and its motion state during the winding process, establishing a material rheology-tension coupling model through indoor experiments on the correlation between the rheological properties of the rubber strip and tension changes under different working conditions. This invention has the advantage of achieving adaptive adjustment of the rubber strip tension.

The invention relates to the technical field of building construction, in particular to a novel anti-floating anchor rod waterproof joint treatment method which comprises the steps that an anti-floating anchor rod and peripheral inter-pile soil are cleaned, the end of the anchor rod is treated, pile heads are chiseled, and a waterproof base layer is obtained; determining whether the qualification of the waterproof base layer meets the requirement or not based on the flatness deviation ratio of the waterproof base layer at the end of the anchor rod; the base layer is subjected to concrete pouring, the surface of the base layer is coated with a cement-based capillary crystalline waterproof coating to obtain a waterproof groove, and an SBS coiled material reinforcing ring is arranged on the periphery of the waterproof groove; filling the waterproof groove with a non-cured rubber asphalt waterproof coating to obtain a waterproof filling layer; the filling compactness of the waterproof filling layer is obtained, and the brushing thickness of the waterproof additional layer is determined; the surfaces of the waterproof filling layer and the reinforcing ring are coated with asphalt waterproof paint to obtain a waterproof additional layer; and determining the temperature correction value of the hot melting edge of the SBS coiled material based on the deviation value of the lap width of the waterproof additional layer. The sealing impermeability of the waterproof joint at the end of the anti-floating anchor rod is improved.

The utility model relates to the technical field of PP plate processing equipment, and discloses a PP plate traction device which comprises a first mounting frame and a second mounting frame, positioning blocks are fixedly connected to the upper edges of the inner sides of the first mounting frame and the second mounting frame, and an adjusting assembly is arranged between the first mounting frame and the second mounting frame. The height of the traction assembly between the lead screw sliding frame and the lifting sliding frame can be adjusted through the adjusting assembly and rotation of the electric lead screw, the distance between the upper electric rotating roller and the lower electric rotating roller can be adjusted through lifting sliding of the first electric lifting sliding base and the second electric lifting sliding base, and meanwhile the distance between the upper electric rotating roller and the lower electric rotating roller can be adjusted.
