Working Principle ①, The garment linear vibration friction embossing machine uses the frictional heat energy generated on the contact surface of the two workpieces to be welded to melt the plastic. The thermal energy comes from the reciprocating movement of a workpiece on the other surface with a certain displacement or amplitude under a certain pressure. Once the desired degree of heat sealing is achieved, the vibration will stop, and at the same time, a certain pressure will still be exerted on the two workpieces, so that the just-sealed parts will cool and solidify, thereby forming a tight bond. ②, Garment orbital vibration friction embossing machine is a method of heat sealing using frictional heat energy. During orbital vibratory friction sealing, the upper workpiece orbits at a fixed speed-circular motion in all directions. The movement can generate thermal energy, so that the heat-bonding part of the two plastic parts reaches the melting point. Once the plastic begins to melt, the movement stops and the heat-bonded parts of the two workpieces solidify and firmly jo

    Application of Hot Melt Glue Machine in Cable and Optical Cable

    Hot melt gluers are not only widely used in the packaging industry, but are also often used in some public equipment. Like some cables or fiber optic cables, due to the exposure to wind and sun over the years, good waterproof and moisture resistance is required to ensure the performance and design life of the cable and cable. At present, the number of metal communication cables produced and used in China is the largest in the city. The conductive medium of urban communication cables is copper conductors. The polyolefin material is extruded on the surface of the copper wire as an insulating layer, and the entire cable is encapsulated with the polyolefin material. Polyolefin material is a kind of polymer material. The gap between polyolefin molecules is large, and the diameter of water molecules is small. Therefore, polyolefin materials cannot prevent the penetration of water molecules. The waterproof and moisture-proof performance of cables is very important. Moisture will reduce the insulation resistance of the cable core wire, other electrical parameters will also change, and it will also cause corrosion of the copper wire. Metal tape (aluminum tape or steel tape, etc.) is often used as a moisture barrier for cable jackets. The metal bars are filled with dry air or grease to keep the core dry. In the sheathing process for cable production, straight metal strips are rolled into cylinders through longitudinal wrapping dies, so there are overlapping seams. In order to improve the flexibility and lateral pressure resistance of the cable, the metal strip is often embossed. Influence of water and humidity resistance. At the same time, after the contact area of the metal tape is reduced, the peeling force of the lap joint of the metal tape is reduced, resulting in unqualified cables. In order to solve the above problems and ensure the normal service life of the cable, people often use a hot melting point glue machine to connect the meta

    Introduction to the Industry Application Classification of Hydraulic Press

    There are many types of hydraulic presses in various structures. The purpose is also different from the structure type of the machine. So today we come to understand the application classification of hydraulic presses. 1. Three-beam and four-column hydraulic press. This is the most common type of structure, especially a structure type commonly used by large free forging hydraulic presses. 2. Integral frame hydraulic press. The main frame is integrally welded or integrally cast, as shown in the following pull-type free forging hydraulic press. 3. Single-arm hydraulic press. This structure is mostly used for stamping hydraulic presses or small correction hydraulic presses. The frame of the single-arm hydraulic press is an integral cast steel structure or a steel plate welded structure. The structure is simple, and the workpiece can be approached from three directions when working, and the operation is simple and convenient. In order to ensure that the frame has sufficient strength and rigidity, sometimes the frame is made relatively cumbersome, but the accuracy of the machine stamping and calibration work is guaranteed, and the processing efficiency is improved at the same time. 4. Three-beam and multi-column combined type. For large-scale die forging hydraulic presses, the large tonnage makes the design of the body structure more complicated. Due to the constraints of manufacturing, installation, and transportation, the split combined structure is often used. 5. Multi-board combined frame type. For large multi-directional die forging hydraulic presses, its large tonnage and higher requirements for press rigidity make the body structure design more complicated. 6. Steel belt winding frame type. The frame of the pre-stressed hydraulic press made of steel belt winding has the characteristics of light st
