An edge-sealing device for high-hardness PVC boards Technical Field

[0001] This utility model relates to the field of edge banding technology, specifically to an edge banding device for high-hardness PVC boards. Background Technology

[0002] PVC sheets are widely used in many industries such as furniture manufacturing and building decoration due to their advantages such as low cost, ease of processing, and corrosion resistance. Edge banding is a crucial step in the processing of PVC sheets. It not only enhances the aesthetics of the sheets but also effectively prevents damage to the edges, extending their lifespan.

[0003] Existing PVC board edge banding devices on the market have many shortcomings. Most edge banding devices lack flexibility in design, have fixed structures, and are difficult to effectively band PVC boards of different thicknesses. When edge banding is required for boards of different thicknesses, a lot of time and manpower are often needed to replace the corresponding molds or adjust the parts of the device. This not only reduces production efficiency but also increases production costs. Therefore, we propose an edge banding device for high-hardness PVC boards. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an edge-sealing device for high-hardness PVC boards, which has the advantage of conveniently sealing the edges of boards of different thicknesses. This solves many problems existing in the market for PVC board edge-sealing devices. Most edge-sealing devices lack flexibility in design, have fixed structures, and are difficult to effectively seal the edges of PVC boards of different thicknesses. When it is necessary to perform edge-sealing operations on boards of different thicknesses, a lot of time and manpower are often required to replace the corresponding molds or adjust the parts of the device. This not only reduces production efficiency but also increases production costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing device for high-hardness PVC sheets, comprising a connecting frame, a housing fixedly connected to the top left side of the connecting frame, a lead screw movably connected to one side of the housing, a threaded sleeve threaded to the surface of the lead screw, movable rods movably connected to both the front and back of the threaded sleeve, a connecting seat movably connected to one side of the movable rod, an adjusting plate fixedly connected to one side of the connecting seat, a fixed rod fixedly connected to one side of the adjusting plate, a vertical plate fixedly connected to one side of the fixed rod, a fixed shaft fixedly connected to one side of the vertical plate, a material roller inserted into one side of the fixed shaft, a connecting rod fixedly connected to the other side of the vertical plate, a fixed frame fixedly connected to one side of the connecting rod, and a limit roller movably connected to one side of the fixed frame.

[0006] Preferably, a spring is fixedly connected to the right side of the top of the connecting frame, a horizontal plate is fixedly connected to the top of the spring, and a cutter is fixedly connected to one side of the horizontal plate.

[0007] Preferably, rectangular grooves are provided on both the front and back of the housing, and the inner cavity of the rectangular groove is slidably connected to the fixing rod.

[0008] Preferably, both sides of the inner cavity of the housing are movably connected to the lead screw via bearings, and a rotating handle is fixedly connected to the left side of the lead screw.

[0009] Preferably, an extrusion roller is movably connected to the inner side of the connecting frame, and a handle is fixedly connected to the top of the housing.

[0010] Preferably, a rectangular plate is slidably connected to the inner cavity of the horizontal plate, and the bottom of the rectangular plate is fixedly connected to the connecting frame.

[0011] Compared with the prior art, this utility model provides an edge sealing device for high-hardness PVC boards, which has the following beneficial effects:

[0012] 1. When adjustment is required, the lead screw is rotated, which drives the threaded sleeve to move. The threaded sleeve drives the movable rod to move, the movable rod drives the connecting seat to move, the connecting seat drives the adjusting plate to move, the adjusting plate drives the fixed rod to move, the fixed rod drives the vertical plate to move, and the vertical plate drives the fixed shaft to move. This moves the fixed shaft away from the material roller, making it easier to replace the material roller with one of different sizes. After replacement, the lead screw is rotated in the opposite direction to allow the fixed shaft to engage with the material roller. At the same time, the vertical plate drives the connecting rod to move, the connecting rod drives the fixed frame to move, and the fixed frame drives the limiting roller to move. As the fixed shaft engages with the material roller, the limiting roller moves to the working position, making it convenient to use.

[0013] 2. After the sealing is completed, press the horizontal plate down. The horizontal plate moves the cutter to cut the seal. Then release the horizontal plate. At this time, the spring pushes the horizontal plate up, so that the cutter returns to its original position. Attached Figure Description
