Technical Field
[0001] This invention relates to the field of handrail technology, specifically to a novel galvanized steel wire polyurethane handrail and its manufacturing method. Background Technology
[0002] The handrail system is an important safety component in escalators. Its primary function is to prevent passengers from accidentally slipping off the escalator. Secondly, because the handrail runs synchronously with the steps, it ensures that passengers can stand firmly and not fall. Escalators only gradually entered the practical stage after being equipped with handrail systems, and this is now a necessary device for escalators.
[0003] Existing polyurethane handrails are composed of polyurethane, copper-plated steel wire rope, and canvas. The copper-plated steel wire rope is coated with glue and dried before being extruded together with the polyurethane and canvas. Therefore, glue is required to ensure the pull-out force of the polyurethane and steel wire rope. The glue has high VOC pollution, high energy consumption during glue drying, and high glue and electricity costs. To address this, we provide a new type of galvanized steel wire polyurethane handrail and its manufacturing method. Summary of the Invention
[0004] The purpose of this invention is to provide a novel galvanized steel wire polyurethane handrail and its manufacturing method, in order to solve the problems mentioned in the background art, which are that the existing polyurethane handrail is composed of polyurethane, copper-plated steel wire rope and canvas. The copper-plated steel wire rope is coated with glue and dried before being extruded together with polyurethane and canvas. Therefore, glue is required to ensure the pull-out force of polyurethane and steel wire rope. The glue has high VOC pollution, high energy consumption during glue drying, and high glue and electricity costs.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel galvanized steel wire polyurethane handrail belt, comprising a handrail belt body, wherein a tensile layer is provided at the upper end of the handrail belt body, and a sliding layer is provided between the two ends of the handrail belt body and the lower part of the tensile layer, wherein the inner wall of the sliding layer is wrapped with canvas; Also includes: A steel wire layer is disposed inside the tensile layer, and a plurality of galvanized steel wire ropes are disposed inside the steel wire layer. The V-shaped block is located at the lower end of the tensile layer, and the V-shaped block and the handrail belt body are an integral structure.
[0006] Preferably, a first reinforcing layer is provided at the upper end of the steel wire layer, a second reinforcing layer is provided at the lower end of the steel wire layer, and a polyurethane surface layer is provided at the upper end of the first reinforcing layer.
[0007] Preferably, the manufacturing method of the novel galvanized steel wire polyurethane handrail includes the following steps: Step 1: Raw material selection. Select galvanized steel wire rope with suitable diameter and structure, install it on the unwinding machine, and pull it directly through the mold. Step 2: Drying TPU. Place the TPU granules in an oven for drying at 100-110℃ for 30 minutes to 2 hours. The maximum allowable moisture content of the material during TPU processing is 0.1%. Step 3: TPU extrusion. Add the dried TPU granules to the extruder and heat them. Set the temperature of the extruder barrel to 170-230℃. Step 4: Wrap the steel wire, then extrude the heated TPU material through an extruder and die to shape it, and then follow the instructions. Figure 2 The structure is wrapped around the galvanized steel wire rope selected in step 1; Step 5: Cover with canvas and install the canvas inside the handrail as shown in the diagram. Figure 2 ; Step Six: Cooling and Shaping. The processed handrail belt is pulled by a traction machine through a cooling water tank for cooling treatment. The water temperature in the cooling water tank is 10~20℃. Step 7: Cutting and splicing. The new galvanized steel wire polyurethane handrail belt is fed to the cutting machine, cut to the required length, and then spliced at both ends to form a ring to complete the finished product. The galvanized steel wire rope is composed of the following structure: the steel wire body is high-strength steel wire drawn into shape, and the surface is a hot-dip galvanized layer. Between the galvanized layer and the steel wire rope is a zinc-iron alloy layer. The galvanized layer and the zinc-iron alloy layer provide the steel wire with excellent corrosion resistance. The present invention uses a thick galvanizing process. The excess galvanized layer on the surface provides additional lubrication between the steel wires. This lubrication allows the steel wires to play a surface protection role when subjected to friction, avoiding fatigue fracture caused by local pitting corrosion and increasing service life. The galvanized steel wire cord has a 3+9 structure, with three 0.278mm diameter steel wires inside and nine 0.304mm diameter steel wires outside. The inner and outer twist directions of the steel wires are both S or Z, and the contact between the wires with the same twist direction changes from point contact to line contact. This increases the rate of damage caused by friction on the surface of the steel wire during fatigue bending, thereby extending the life of the steel wire. The number of outer steel wires has been reduced from the traditional six to nine, which also helps to improve the bending fatigue life of the steel cord. The fatigue life is increased by more than 2 times according to the three-roll bending fatigue test. With the above changes, adhesives are no longer used to bond the steel wire and polyurethane in the production process, reducing the use of solvent-based adhesives and greatly reducing VOC emissions. The thick galvanized surface of the steel wire has a rough surface that can form a mechanical interlock with the polyurethane. After bending fatigue, the higher fatigue performance of the steel wire can compensate for the decrease in bonding ability, so that the overall fatigue performance of the handrail is equivalent to that of the current product, but this product greatly reduces VOC emissions in the manufacturing process. The cutting machine includes a support base, a movable cavity at the center of the support base, connecting frames at both ends of the movable cavity and welded to the support base, a conveying mechanism inside the movable cavity, a transmission roller inside the conveying mechanism, and a cutting blade above the conveying mechanism.
[0008] Preferably, the upper end of the cutting blade is provided with a blade fixing frame, and the cutting blade is fixed to the blade fixing frame by an external bolt, and a cutting frame is provided on the upper exterior of the blade fixing frame.
[0009] Preferably, the cutting frame has an internal mounting base plate, a servo motor is provided on one side of the mounting base plate, a ball screw is provided at one end of the servo motor, a screw moving seat is provided outside the ball screw, and the screw moving seat moves laterally along the ball screw. The blade fixing frame is fixed to the screw moving seat by external bolts.
[0010] Preferably, the lower surface of the cutting frame is provided with a movable opening, and the movable opening is an integral structure with the cutting frame.
[0011] Preferably, the upper end of the cutting frame is provided with a protective plate, and both ends of the protective plate are provided with protective plate fixing pieces, and the protective plate fixing pieces are threadedly connected to the cutting frame by external bolts.
[0012] Preferably, both ends of the cutting frame are provided with a heightening frame, and the heightening frame and the cutting frame are an integral structure. A side fixing plate is provided on one side of the heightening frame, and the side fixing plate and the heightening frame are an integral structure. The side fixing plate is threadedly connected to the support seat by threaded fasteners.
[0013] Preferably, the conveying mechanism is provided with fixed clamps on both sides, and an electric push rod mechanism is provided on one side of the fixed clamp. The connection end of the electric push rod mechanism and the fixed clamp is provided with a fixed plate, and the fixed plate is welded to the electric push rod mechanism. Fixed bolts are provided around the fixed plate, and the fixed plate is threadedly connected to the fixed clamp through the fixed bolts.
[0014] Preferably, the electric push rod mechanism is provided with a push rod fixing frame on the outside, and both ends of the push rod fixing frame are provided with hexagonal bolts, and the push rod fixing frame is fixedly connected to the support base by the hexagonal bolts.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention incorporates a steel wire layer within the tensile layer of the handrail belt body, and a galvanized steel wire rope within this layer. The internal tensile layer of the handrail belt body is a high-strength galvanized steel wire rope with a suitable diameter and structure, ensuring the tensile strength of the handrail belt. The galvanized surface layer ensures the adhesion between the steel wire rope and the polyurethane. The galvanized steel wire rope has a diameter of 1.13mm, a structure of 3*0.2+9*0.35, a breaking strength of over 1800N, and the same twist direction for both inner and outer layers. The galvanized weight is 20-40g / kg. The identical twist direction ensures line contact between the wire rope strands, reducing the possibility of early fatigue peeling due to mutual friction. The thicker galvanized layer not only protects the steel wires from punctures but also increases the self-lubricating ability between the wires, providing a longer service life. The relatively rough structure of the hot-dip galvanized surface enhances the initial adhesion to the polyurethane. Because the galvanized steel wire strands are relatively thin… Therefore, the bending fatigue performance of the steel wire is better than that of the traditional structure. In summary, the basic product does not require the addition of a special adhesive coating. The new polyurethane handrail belt of this application is composed of polyurethane, galvanized steel wire rope, and canvas. It can be formed by directly passing the galvanized steel wire rope through the mold and extruding it together with the polyurethane and canvas. The galvanized layer of the steel wire has good adhesion to the polyurethane, which can meet the usage requirements. Compared with the existing copper steel wire rope, which requires glue to ensure the pull-out force of the polyurethane and steel wire rope, its advantages are: environmentally friendly performance with no VOC pollution, low energy consumption without heating and drying, and low cost. This application reduces the VOC of glue to 0, the energy consumption of glue drying to 0, and the glue cost to about 20%. That is, compared with copper plating, the cost increase of galvanizing is only about 20% of the glue and electricity costs. At the same time, the adhesion between the glue-free galvanized steel wire rope and polyurethane is 1.6 times that of the glue-free copper steel wire rope and polyurethane, exceeding the required specifications by 20%.
[0016] 2. The main body of the handrail is made of polyurethane, a high-elastic material that is fatigue-resistant and bend-resistant, ensuring the bending operation of the handrail. Furthermore, the main body of the handrail is made of polyurethane material with good hygiene properties, which can come into direct contact with the human body. The inner side of the main body of the handrail is equipped with a friction-resistant and anti-static canvas layer, which uses 0.8mm thick nylon canvas with conductive fibers to achieve wear-resistant and anti-static effects, improving service life and safety of use.
[0017] 3. By installing V-shaped blocks of polyurethane material on the lower side of the sliding layer of the handrail body, the handrail is ensured to remain centered during operation. The excellent wear resistance of polyurethane material ensures the service life of the handrail. TPU material with a hardness of 85~95A is used. Attached Figure Description
