By arranging a main upper vibrating pipe, a retaining piece and an auxiliary vibrating pipe on the vibrating pipe, the inside of the concrete is enabled to reach a uniform state; the hydraulic rod and the trowelling piece are mounted on the leveling device, so that working performance of the trowelling piece can be improved.

The invention relates to a painting production line for leveling natural stone paint external thermal insulation decorative boards, which sequentially includes a substrate conveyor belt, a primer spraying machine, a conveyor belt after primer spraying, a multi-color natural stone paint spraying machine, a stone paint spraying conveyor belt, and a stone paint spraying machine. Quality paint layer drying room, top paint spraying machine, conveyor belt after top paint spraying, primer drying room and cooling fan are installed on the conveyor belt after primer spraying, and the conveyor belt after spraying stone paint is a flexible wide belt with air holes , and a gas vibrator is arranged under the conveyor belt, and a topcoat drying chamber is arranged on the conveyor belt after the topcoat is sprayed. The painting production line has high production efficiency, low cost, and low labor intensity. The primer, natural stone paint, and top paint are sprayed and dried separately, and the paint layer is stable and firm. Flattening and drying cooperate with each other, which not only ensures the flatness, but also realizes the realistic simulation effect. The paint recycling rate is high, and the pollution to the environment is avoided, and the environmental protection is good.

The invention discloses a circulative drying and deodorizing desizing machine which belongs to the technical field of fabric desizing. The circulative drying and deodorizing desizing machine comprisesguide rollers, seal parts and an outer box, wherein the outer box is of a square box body structure, one inner cavity of the outer box is separated into a receiving guide cavity, a deodorizing cavity, a drying cavity and a heating cavity, the rear wall of one inner cavity of the left portion of the deodorizing cavity is provided with liquid injecting pipelines, an overflowing pipeline and liquiddischarging pipelines, a heat insulation plate is arranged between the drying cavity and the heating cavity, and one inner cavity of the upper right portion of the drying cavity is provided with a support plate. According to the circulative drying and deodorizing desizing machine, fabrics enter into the deodorizing cavity to be subjected to soaking-rolling deodorizing and then enter into the drying cavity to be dried, the fabric wave-rising phenomenon can be reduced by a wave flattening device, the flattening effect of squeeze rollers on the fabrics is guaranteed, namely appearance of the situation of the fabrics being pleated is reduced, and increasing of the qualified rate of the fabrics is facilitated.

The invention relates to a high-frequency induction welding method for terminals of storage batteries. The high-frequency induction welding method comprises the following working steps of a, a prepressing and feeding-in procedure is performed, namely, the to-be-welded storage batteries are moved to a position right below a set position of a welding gun in sequence, a gun head is driven by a driving mechanism to move downwards till a welding assembly abuts against one storage battery, the gun head moves downwards continually till a control unit above the welding assembly makes contact with a pressure sensor, and posts on the storage battery are heated by the welding assembly through a high-frequency electromagnetic induction heating method; b, a reshaping procedure is performed, namely, thegun head moves downwards continually, the heated and softened posts on the storage battery are pressed down synchronously by the welding assembly till the posts make contact with wiring pieces of theterminals, and the flattening of the end portions of the posts is completed; c, a welding procedure is performed, namely, after step b is completed, in the process that the gun head is driven by thedriving mechanism to move upwards to the initial position, the welding assembly breaks away from the posts, and the surface fusion welding of the posts is completed. By means of the high-frequency induction welding method for the terminals of the storage batteries, the conventional storage battery welding procedure is simplified, and the automated and continuous production of the storage batteriesis facilitated.

The invention relates to a high-frequency welding induction gun head and a welding gun with the gun head applied. The welding gun comprises a gun body, a drive mechanism and the gun head; the gun head comprises a connection cover and a casing pipe; the gun body comprises a gun head base, a welding assembly and a control assembly; the welding assembly is installed on the front end portion of the gun head base and comprises a magnetic conductive bar and an electromagnetic induction coil surrounding the magnetic conductive bar; the control assembly is arranged on the rear side of the welding assembly and comprises a control unit and a pressure sensor arranged on the rear side of the control unit; the front end of the control unit is in abutting connection with the magnetic conductive bar; and the rear end of the control unit is in non-contact connection with the pressure sensor. Shaping and fusion welding on a post terminal are completed synchronously in the welding process of a storage battery connecting terminal through cooperation of a high-frequency electromagnetic induction heating mode and lifting movement of the gun head, the traditional welding procedure is simplified, and full-automatic and mechanical welding production of the storage battery connecting terminal is easily achieved by being matched with a mechanical arm.

The invention provides a plastic film preparation and leveling machine, which belongs to the technical field of plastic film leveling. Connected to the front and rear ends of the bottom plate, and any side of the regular polygon side plate is completely connected to the bottom plate, and the symmetrical regular polygon side plates are connected with a first leveling component and a second leveling component. The summation is equal to the number of sides of the regular polygon side plates, and they are respectively connected to the corners of the regular polygon side plates correspondingly in rotation, and a central inflatable piece is connected between the symmetrical regular polygon side plates. The plastic film preparation and leveling machine can effectively tension and level the wrinkles in the longitudinal direction and the transverse direction of the plastic film at the same time, which fully improves the leveling effect of the plastic film. The flat combination improves the controllability of the plastic film leveling process.
