Description

Technical Field

[0001] The utility model relates to the technical field of automatic coating of a large-arc plastic part with an anti-wrapped mesh fabric, and particularly relates to an automatic edge-wrapping hot-melt device. Background Art

[0002] For wrapping a mesh fabric on a large-arc (convex) plastic part with the fabric being anti-wrapped on the inner side wall, it is all completed by manual operation, which has many problems. When in use, the fabric will be enlarged to avoid the deviation of manual wrapping. After the fabric is anti-wrapped, the excess material still needs to be trimmed manually. Through manual wrapping, the force is uneven, the traces of the horn holes on the plastic are highlighted, and at the same time, the fabric texture is uneven. When the fabric is anti-wrapped to the inner side wall, it needs to be brushed with glue and pasted manually, which takes a long time and will cause poor surface glue, resulting in the use of glue for the product, which is not environmentally friendly. Therefore, an automatic edge-wrapping hot-melt device will be used.

[0003] When the existing edge-wrapping hot-melt device is in use, due to its inconvenient folding of the edge, manual wrapping is time-consuming and laborious. At the same time, the fabric is prone to uneven force, which is inconvenient to reduce the quality defects of uneven fabric texture and the highlighting of horn hole traces, making its working efficiency low when in use. Summary of the Utility Model

[0008] At the edge of the top end of the bottom mold, a folding edge structure is installed. The folding edge structure includes a fixed seat, an electric push rod, a sliding rod, and an arc-shaped push block. The fixed seat is fixed at the edge of the top end of the bottom mold. On one side inside the fixed seat, the electric push rods penetrate through. At one end of each electric push rod, an arc-shaped push block is fixed. The sliding rods penetrate through the inside of the fixed seat on one side of each electric push rod.

The bottom of the flow distribution seat is provided with an air inlet. The air suction frame is fixed on one side of the top of the top plate. A fan is installed inside the air suction frame. One side of the air suction frame is fixed with a connecting pipe. Start the fan to make the gas enter the inside of the connecting pipe through the air inlet. Under the action of the protective net and the dust-proof net, impurities are prevented from damaging the fan. At this time, the ejector pin rises under the action of suction. Under the action of the limit block, the ejector pin and the bottom die are prevented from separating from each other.

[0011] Preferably, a dust-proof net is fixed on the side of the air suction frame away from the connecting pipe. The end of the connecting pipe away from the air suction frame is communicated with the air inlet. The top of the connecting rod extends above the top plate. A protective net is arranged at the bottom of the air inlet. The convex plastic part is reversely adsorbed at the bottom end of the adsorption head. The fabric is laid flat on the cavity on the top of the bottom die. The 8 holes at the edge of the fabric are sleeved outside the ejector pin for fixation. Start the first hydraulic telescopic rod. The first hydraulic telescopic rod drives the adsorption head to move downward. The adsorption head drives the convex plastic part to fit with the fabric.

The moving seat drives the bottom die to move, so that the bottom die moves below the hot-melt head.

[0014] Preferably, the top end of the movable seat extends to the outside of the base and is fixedly connected to the bottom end of the bottom mold. The movable seat and the base form a sliding structure through the movable slot. One end of the threaded rod extends to the outside of the base and is fixedly connected to the output end of the servo motor. When the servo motor is started, the servo motor drives the threaded rod to rotate inside the movable slot. The threaded rod drives the movable seat to move. Through the sliding structure formed by the movable seat and the movable slot, it is avoided that the movable seat rotates following the threaded rod. The movable seat drives the bottom mold to move, so that the bottom mold moves below the hot melt head.

[0018] By setting an adsorption structure, the fan is started, so that the gas enters the inside of the connecting pipe through the air inlet. Under the action of the protective net and the dust-proof net, impurities are prevented from damaging the fan. At this time, the ejector pin rises under the action of suction. Under the action of the limit block, the ejector pin and the bottom mold are prevented from separating from each other. The convex plastic part is reversely adsorbed at the bottom end of the suction head. The fabric is laid flat on the cavity on the top of the bottom mold. The 8 holes at the edge of the fabric are sleeved outside the ejector pin for fixation. The first hydraulic telescopic rod is started.

At this time, the fan is turned off, and the ejector pin will move downward and return to its original position, realizing the function of the device being convenient for adsorption, thereby improving the applicability of the automatic edge-wrapping hot melt device during use;

[0019] By setting up a moving structure, the servo motor is started. The servo motor drives the threaded rod to rotate inside the movable slot. The threaded rod drives the moving seat to move. Since the moving seat and the movable slot form a sliding structure, the moving seat is prevented from rotating along with the threaded rod.
