Description

Technical Field

[0001] This application relates to the field of hot melt pressing machines, and more specifically, to a hot melt pressing machine for preventing adhesion. Background Technology

[0002] Hot melt pressing machines are widely used in garment processing, footwear manufacturing, bag production, and composite material manufacturing. Their working principle is mainly to melt materials such as hot melt adhesive film and hot melt adhesive mesh through heating and pressure, thereby firmly bonding two or more layers of substrate together.

[0003] Currently, existing hot melt pressing machines generally suffer from the problem of the hot press plate sticking to the workpiece. During the pressing process, the molten adhesive is prone to overflow and solidify on the surface of the hot press plate, or the workpiece may be attracted by static electricity. This not only causes the workpiece to be lifted, the product to be deformed and scrapped, but also requires frequent machine shutdowns for manual cleaning, which seriously restricts production efficiency and affects the stability of product quality. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, the present invention proposes an anti-adhesion hot melt pressing machine, comprising: a base, the base including an operating table and a pad, both of which are mounted on the base; a hot pressing assembly, the hot pressing assembly including a drive cylinder, a power supply box, multiple guide columns, a connecting plate, and a hot pressing plate, the drive cylinder being mounted on the top of the power supply box, and the output shaft of the drive cylinder passing through the power supply box; the upper ends of the multiple guide columns being fixedly connected to the bottom surface of the power supply box, and the lower ends being fixedly connected to the upper surface of the pad; the connecting plate being slidably mounted on the guide columns, and the upper surface of the connecting plate being fixedly connected to the output shaft of the drive cylinder; the hot pressing plate being fixedly mounted on the lower surface of the connecting plate; the lower surface of the hot pressing plate having multiple mounting holes, each mounting hole containing an ejector assembly, the ejector assembly including an ejector spring and an ejector block, one end of the ejector spring being fixedly connected to the bottom wall of the mounting hole, and the other end being fixedly connected to the ejector block.

[0006] In this technical solution, the base includes an operating table and a pad, both of which are mounted on the base. The operating table controls the hot melt pressing machine, facilitating operator operation. The pad supports molds for different hot-pressed products. The hot-pressing assembly includes a drive cylinder, a power supply box, multiple guide columns, a connecting plate, and a hot-pressing plate. The drive cylinder is located on top of the power supply box, and its output shaft passes through the power supply box. The drive cylinder provides power to the connecting plate, enabling its lifting and lowering. The power supply box provides electrical support to all components in the hot melt pressing machine. The upper ends of the multiple guide columns are fixedly connected to the bottom surface of the power supply box, and their lower ends are fixedly connected to the upper surface of the pad. The connecting plate is slidably mounted on the guide columns, and its upper surface is fixedly connected to the output shaft of the drive cylinder. The hot-pressing plate is fixedly mounted on the lower surface of the connecting plate. The guide columns support the power supply box and the drive cylinder. Furthermore, it provides guidance for the lifting and lowering of the connecting plate. The drive cylinder drives the connecting plate to rise and fall in the axial direction of the guide column through the output shaft. The connecting plate drives the hot press plate to rise and fall, thereby completing the hot pressing operation. The lower surface of the hot press plate has multiple mounting holes, and each mounting hole is equipped with an ejector assembly. The ejector assembly includes an ejector spring and an ejector block. One end of the ejector spring is fixedly connected to the bottom wall of the mounting hole, and the other end is fixedly connected to the ejector block. The ejector assembly is used to eject the material from the surface of the hot press plate after the hot melt pressing is completed. When the hot melt pressing machine is working, after the hot press plate comes into contact with the material, the ejector block is compressed by pressure and enters the mounting hole. When the hot press plate leaves the material, the ejector spring returns to its natural state, and the ejector block ejects the material from the surface of the hot press plate, preventing the material from sticking to the hot press plate, thereby avoiding material deformation and scrap, improving the quality of hot-pressed products, and ensuring product stability.

[0007] In addition, the technical solution provided according to the embodiments of this utility model may also have the following additional technical features:

[0008] In the above technical solution, the ejection assembly also includes a limiting block, which is circular and is set in the mounting hole. The ejection spring passes through the central through hole of the limiting block and is connected to the ejection block.

[0009] In this technical solution, the ejection assembly also includes a limiting block, which is circular and set inside the mounting hole. The ejection spring passes through the central through hole of the limiting block and connects with the top block. The circular setting of the limiting block ensures that the ejection spring passes through the limiting block, preventing interference between the ejection spring and the limiting block. Furthermore, the limiting block can block the top block, preventing the top block from completely entering the mounting hole and causing a depression on the lower surface of the hot press plate, which would affect the hot pressing effect.

[0010] In any of the above technical solutions, the limiting block is fixedly installed in the mounting hole, and the vertical distance between the lower surface of the limiting block and the lower surface of the hot press plate is equal to the thickness of the top block.

[0011] In this technical solution, the vertical distance between the lower surface of the limiting block and the lower surface of the hot press plate is equal to the thickness of the top block. This ensures that the lower surface of the top block and the lower surface of the hot press plate are on the same plane during the pressing process, thus guaranteeing the flatness of the lower surface of the hot press plate and preventing the top block from protruding on the lower surface of the hot press plate.

[0012] In any of the above technical solutions, when the ejector spring is in its natural state, the upper surface of the ejector block is located inside the mounting hole, and its lower surface protrudes from the mounting hole.

[0013] In this technical solution, when the ejector spring is in its natural state, the upper surface of the ejector block is located inside the mounting hole, and its lower surface protrudes from the mounting hole. This setting ensures that the ejector block can smoothly enter the mounting hole when the hot press plate is pressed down.

[0014] In any of the above technical solutions, the hot pressing assembly also includes multiple sleeves, which are slidably fitted onto the guide post, and the lower surfaces of the multiple sleeves are fixedly connected to the connecting plate.

[0015] In this technical solution, multiple sleeves are slidably fitted onto the guide post, and the lower surfaces of the multiple sleeves are fixedly connected to the connecting plate. The arrangement of multiple sleeves ensures that the connecting plate remains horizontal during the lifting process, preventing the hot press plate set on the lower surface of the connecting plate from tilting due to the tilting of the connecting plate.

[0016] In any of the above technical solutions, there are also multiple air pumps, which are fixedly installed on the side wall of the power supply box, and air delivery hoses are connected to the air outlets of the multiple air pumps.

[0017] In this technical solution, multiple air pumps are fixedly installed on the side wall of the power supply box, and air delivery hoses are connected to the air outlets of the multiple air pumps. The air pumps are used to apply airflow to the material that has completed the hot pressing and fusion, so that the material is completely separated from the hot pressing plate.

[0018] In any of the above technical solutions, the end of the gas delivery hose away from the gas pump is connected to a rigid gas delivery pipe. The rigid gas delivery pipe is fixedly installed on the side of the connecting plate, and the end of the rigid gas delivery pipe away from the gas delivery hose is close to the lower surface edge of the hot press plate.

[0019] In this technical solution, the end of the air delivery hose away from the air pump is connected to a rigid air delivery pipe. The rigid air delivery pipe is fixedly installed on the side of the connecting plate, and the end of the rigid air delivery pipe away from the air delivery hose is close to the lower surface edge of the hot press plate. The air delivery hose can stretch or contract as the connecting plate rises and falls. The rigid air delivery pipe is used to ensure that the final airflow can accurately act on the connection between the hot press plate and the material, so that the material is blown away from the hot press plate by the airflow and prevents the material from sticking to the hot press plate.

[0034] In the above configuration, the ejector assembly 300 also includes a limiting block 330, which is annular and is disposed within the mounting hole 251. The ejector spring 310 passes through the central through hole of the limiting block 330 and is connected to the top block 320. The annular design of the limiting block 330 ensures that the ejector spring 310 passes through the limiting block 330, preventing interference between the ejector spring 310 and the limiting block 330. Furthermore, the limiting block 330 can block the top block 320, preventing the top block 320 from completely entering the mounting hole 251 and causing a depression on the lower surface of the hot press plate 250, which would affect the hot pressing effect.
