First, the scope of application:
1. Scope of application of tensile testing machine: Tensile testing machine is also called tensile machine. It is mainly used for various physical and mechanical properties of plastic sheet, pipe, profile, plastic film and rubber, wire and cable, waterproof coil, wire and other materials. Test, tensile machine is used for mechanical reinforcement of tensile and compression, bending, shearing, peeling and other mechanical properties of metal materials and non-metal materials. The tensile machine fixture is an important part of the instrument, and different materials need different The fixture is also an important factor in whether the test can be carried out smoothly and the accuracy of the test results is high or low.
2. Scope of application of peeling force testing machine: suitable for plastic film, composite material, soft packaging material, plastic hose, adhesive, adhesive tape, self-adhesive, medical patch, protective film, release paper, combination cover , metal foil, separator, back sheet material, non-woven fabric, rubber, paper fiber and other products such as stretching, peeling, deformation, tearing, heat sealing, bonding, puncture force, opening force, low speed unwinding force, dialing Performance tests such as force.
Second, the structure principle:
1. Tensile testing machine structure principle: The tensile testing machine consists of one or two vertical carrying columns and a liquid crystal display. The supporting column is mounted on a fixed horizontal base with a movable horizontal beam at the top. In most of today's electronic tensile machines, the struts are typically driven by a lead screw to determine the position of the moving beam.
The specifications of the tensile tester are expressed by the combination of the maximum load that the frame can withstand and the maximum load of the load cell. The load unit is mounted on a motor driven or hydraulically driven moving beam. The load cell connected to the fixture measures the force and can be read from a digital display or computer. Many electronic tensile testing machines have interchangeable sensors that match the material to be tested.
2, peeling force testing machine structure principle: the horizontal structure, high-precision gear reduction electronic speed motor drag load chuck, load performance is stable. The whole machine is composed of a drag motor, a main body casing, a microcomputer controller, a micro printer, etc., and the force measuring unit is composed of a high-precision force value sensor and a digital control system using a single chip microcomputer as a central processing unit.
Wine box, usually refers to the box that holds bottled wine. Materials are: Wooden Box, leather box, metal box and paper box. Different shapes for shock and decoration.
Wine box, also known as red wine box, is usually called wine packaging box or red wine packaging box. As the name implies, it is the outer packaging of wine (red wine), which has the function of protecting red wine for convenient transportation and storage, and at the same time, it is beneficial to wine ( red wine).
1. Wine wooden box (red wine wooden box)
Usually include log wine boxes (multi-purpose materials include pine, paulownia, etc.), imitation mahogany wine boxes (multi-purpose materials include MDF, etc.), and the shapes are diverse and are mostly used for medium and high-end wine packaging.
2. Wine leather box (red wine leather box)
Most of the wine leather boxes (red wine leather boxes) are made of PU, PVC and other artificial leather. The leather packaging is more suitable for the characteristics of wine, and can be divided into single-pack, double-pack, four-pack and six-pack in terms of capacity.
3. Metal wine box (metal wine box)
There are few metal wine boxes in the market and are not widely used. Most of them are made of aluminum alloy, iron, and other alloys.
4. Wine carton (red wine carton)
Wine cartons are mostly made of cardboard, corrugated paper, special paper, etc. Since the raw materials are paper, which is convenient for secondary recycling, the shape can be diversified, and other processes are convenient, so wine cartons are widely used in wine packaging.
