The utility model provides a kind of tubular object manufacturing device, the device of the utility model includes: the first slitting assembly of original strip material is divided into at least one wide strip and at least two narrow strips;The glue assembly of one strip surface of the wide strip or narrow strip is coated with glue;The glue coating surface of each wide strip is bonded with at least two adjacent narrow strips with the way that narrow strip is in the same plane through glue coating surface to be double-layer bonded strip bonding assembly;The second slitting assembly of double-layer bonded strip is divided into double-layer strip along the gap between adjacent narrow strips;Forming assembly is curled into continuous double-layer tubular object with the axis parallel to the conveying direction of double-layer strip.This utility model's device effectively improves tubular object roundness, hardness, reduces raw material consumption, and the two layers of double-layer tubular object are completely consistent, can reduce product difference rate, improve product quality, while multi-channel parallel forming can multiply production efficiency.

This utility model relates to the technical field of grinding devices, specifically disclosing a grinding device for sheet metal processing. It includes a wide-surface grinding mechanism for the sheet metal, a long-side grinding mechanism for the sheet metal on one side of the wide-surface grinding mechanism, and a sheet metal conveying mechanism at the end of the wide-surface grinding mechanism away from the long-side grinding mechanism. The wide-surface grinding mechanism of this design uses adjustable grinding rollers arranged symmetrically. The height of the lifting frame is precisely controlled by a cylinder, ensuring close contact between the grinding rollers and sheets of different thicknesses, guaranteeing uniform grinding pressure distribution. Simultaneously, the high-speed rotation of the grinding rollers driven by dual motors, combined with the continuous feeding of the conveyor belt, allows for fine grinding of the entire wide-surface area in one pass, avoiding the surface unevenness caused by uneven force in traditional manual grinding. For the long-side, a linkage structure between a threaded sleeve and a limiting rod allows the two grinding discs to adaptively adjust their spacing, precisely clamping the edge of the sheet metal and grinding it synchronously.

This utility model relates to the field of road and bridge construction technology, and in particular to a road paving device for road and bridge construction. The device includes a vehicle body, a mixing tank fixedly installed on the upper front side of the vehicle body, a discharge mechanism on the lower front side of the vehicle body, a material cylinder rotatably installed at the middle position of the upper end of the vehicle body, a curing film wound onto the material cylinder, and compaction mechanisms on the front and rear sides of the material cylinder. A connecting rod rotatably installs at the end of the vehicle body, and a first roller is rotatably connected to the lower end of the connecting rod. The first roller is driven by a third servo motor mounted on the connecting rod, and its direction of travel is opposite to that of the vehicle body. This application, through the design of mixing, discharge control, and multi-roller operation, achieves a comprehensive improvement in the uniformity, flatness, and curing quality of concrete paving. The mixing system prevents concrete from solidifying, the discharge mechanism precisely controls the amount of material used, and the multiple rollers sequentially complete the paving, film covering, and air bubble elimination, forming a continuous and efficient construction process.
