The invention belongs to the technical field of tire manufacturing, and particularly relates to a rubber material supply assembly and a rubber coating device for anti-puncture tire production, and the rubber material supply assembly comprises a second base, a feeding assembly, a rubber melting assembly, a fourth base and a rotary clamping assembly. The feeding assembly comprises a first motor, a rotary disc and a plurality of glue containing boxes. The glue melting assembly comprises a glue sprayer, a box body and a glue containing assembly; the glue containing assembly comprises an upper glue containing plate and a lower glue containing plate; and the upper glue containing plate and the lower glue containing plate are movably mounted in the box body. The fourth base comprises a second bottom plate and a second side plate; and the rotary clamping assembly comprises a third motor, a third connecting plate and a fourth connecting plate. Manual feeding is avoided through the feeding assembly, the safety of feeding work is ensured, glue melting is quicker through the glue melting assembly, and finally the inner surface of a tire is coated with glue more uniformly through the rotary clamping assembly, so that the glue coating quality is high.

The invention discloses a novel slice type semiconductor ultra-thin packaging device comprising a fixed base. A conveying assembly line extending left and right is arranged in the middle of the upperend surface of the fixed base. Sealing space is formed in the left side inside a fixed case; a hydraulic rod is fixedly connected to the central position of the lower end surface of a sealing plate; the lower end of the hydraulic rod passes through the lower end wall of the sealing space and is fixedly connected with a press-fit plate; a resin conveying device is arranged right below the press-fitplate and includes a winding mechanism and a pulling mechanism. When the packaging device is working, an extruding plate moves up and down along a guiding rod without falling based on cooperation ofan annular clamp plate and an annular clamp slot; the extruding plate can fall to be in contact with the lower end wall of glue storage space to prevent plugging of a glue coating needle due to solidification of lower-end glue liquid not in use for long time; and the resin sheet that is not used can be switched automatically, so that precision is improved and the work efficiency is enhanced.

The invention relates to a vehicle for automatically replacing a battery box. The vehicle for automatically changing a battery box includes a vehicle frame. The vehicle frame is provided with a bracket for placing the battery box. The bracket and the push-pull mechanism for pulling the charged battery box back to the bracket, the push-pull mechanism has a connection structure for pushing and pulling the battery box to perform corresponding actions. Compared with the prior art, the vehicle provided by the present invention integrates a push-pull mechanism. When the battery box needs to be replaced manually, the vehicle for automatically replacing the battery box provided by the present invention can automatically push or pull the battery box back to the bracket, avoiding manual replacement. Loading the battery box reduces the workload of the operator, and at the same time avoids the hidden danger that the battery box may fall when removing or installing the battery box, which may endanger the safety of the operator.

The invention discloses a multi-station reinforcing sheet laminating device for flexible circuit board production, which comprises a fixing support, and is characterized in that a welding bottom plateis fixedly connected between two side walls of the bottom end of the fixing support, a workbench is arranged at the upper end of the welding bottom plate, a plurality of sliding grooves are evenly formed in the surface, which is away from the welding bottom plate, of the workbench, a first sliding block is slidably connected in each sliding groove, the upper end of the first sliding block is fixedly connected with a first connecting rod, and a movable carrier plate is arranged above the workbench. According to the invention, the movable carrier plate is arranged and is matched with an electric sucker, so that the reinforcing sheet can be fed, the manual feeding is avoided, the manual labor time is saved, and the production cost of the factory is reduced. Meanwhile, compaction rollers aredriven down by a single-track servo electric cylinder, and the laminating effect of the reinforcing sheet can be increased under the movement of the movable carrier plate. The mechanism adopted in thedesign is simple, high in efficiency and easy to repair and maintain, the workload of workers can be reduced, and the laminating operation efficiency is greatly improved.

The invention discloses an automatic prestress clamp which comprises a force bearing upright, a force applying mechanism and a force bearing mechanism, wherein the force applying mechanism and the force bearing mechanism are fixed on the force bearing upright, and are combined to apply prestress to a workpiece; the force bearing mechanism is composed of a group of symmetric mechanical force arms; the two mechanical force arms are fixed at the proper positions of the side surface of the force bearing upright respectively; the front ends of the two mechanical force arms are bent respectively to form force bearing points; the other end of each mechanical force arm extends out to form two fixed points; the main body of the force applying mechanism is a worm gear jack; the body of the work gear jack is fixed on the force bearing upright and positioned in the center of the connection line of the two mechanical force arms; the front end of an ejector rod of the work gear jack serves as a force applying point, and the other end of the ejector rod extends into a cavity of the force bearing upright; a limiting switch of the ejector rod is fixed in the cavity of the force bearing upright.

The invention discloses a compound loading test system for a power transmission infrastructure. The compound loading test system for the power transmission infrastructure comprises a rigid frame, and is characterized by also comprising a vertical guide device; the vertical guide device and the rigid frame are fixedly connected with a vertical mobile platform; a horizontal guide device is placed on the vertical mobile platform and is fixedly connected with the vertical mobile platform; a horizontal mobile frame is fixedly connected with the horizontal guide device in a sleeving manner; a vertical loading device is placed at the lower end of the horizontal mobile frame and is fixedly connected with the lower end of the horizontal mobile frame; a horizontal loading device is hinged to the vertical loading device; a test piece clamp is placed below the vertical loading device and is hinged to the vertical loading device. When the compound loading test system for the power transmission infrastructure works: (1) the horizontal loading device applies horizontal force or horizontal displacement to a test component; (2) the vertical loading device provides the same vertical load to act on the test component directly; (3) the vertical loading device applies different vertical displacement to realize moment loading; (4) the pre-applied three-component load is split to obtain a loading displacement function, so as to realize a compound action of a horizontal load (H), a vertical load (V) and a moment load (M).
