Description

Technical Field

[0001] The utility model relates to the technical field of foam board traction, in particular to a traction machine for producing PVC foam boards. Background Art

[0002] The main component of PVC foam board is polyvinyl chloride, which is used in many industries such as building materials, packaging, and medicine. PVC foam board has become a popular and widely used synthetic material today because of its unique characteristics such as waterproofness, fire resistance, and easy molding, as well as its simple production process. The production of PVC foam board generally involves feeding the raw materials into the extruder through a feeding device for mixing and foaming, and then extruding them into a molding mold for molding. The formed board will be cooled and shaped in a setting machine, and then pulled by a traction device to the cutting machine for cutting to a fixed width and length to obtain the product. Usually, the thickness of the PVC foam board after being shaped in the setting machine is relatively thin, and the problem of uneven cooling will occur when the board is cooled in the setting machine. When the board comes out of the setting machine, the thinner board is prone to deformation, resulting in an uneven surface of the board, which affects the quality of the PVC foam board product.

[0003] Patent 202022161012.6 discloses a PVC foam board traction machine with a board heating function, which belongs to the technical field of PVC foam board production equipment, and includes a roller frame and a traction device arranged at the output end of the roller frame; the roller frame is provided with a heating roller group and several guide rollers, and the traction plane of the traction device is at the same height as the upper end surface of the guide roller; the heating roller group includes an upper heating roller and a lower heating roller, and the upper heating roller and the lower heating roller are jointly connected to an oil temperature machine; the upper heating roller is used to heat the upper surface of the PVC foam board, and the lower heating roller is used to heat the lower surface of the PVC foam board.

[0004] The above technical solution uses upper and lower heating rollers to heat and form the PVC foam board. However, due to the gap between the upper and lower heating rollers and the lack of positioning mechanisms at both ends of the upper and lower heating rollers, the PVC foam board is prone to bending when moving to the gap between the upper and lower heating rollers. In addition, the PVC foam board is squeezed by the upper and lower heating rollers and there is a risk of thinning and lateral movement. Utility Model Content

[0005] The purpose of the utility model is to address the shortcomings of the existing technology and provide a traction machine for the production of PVC foam boards. The sealed shaping box structure is combined with an adjustable extrusion plate structure to achieve the positioning function of shaping the PVC foam boards, thereby solving the problem of deformation of the PVC foam boards due to insufficient extrusion after being softened by heat.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a traction machine for producing PVC foam boards, comprising a base and a shaping box with a trapezoidal structure fixed to the top of the base, a traction plate being provided at the top of the base, and a traction mechanism connected to the traction plate being provided on the side wall of the base, a PVC foam board main body fixed to the traction plate being embedded in the shaping box, and extrusion plates tightly connected to the PVC foam board main body being provided on both sides of the inner wall of the shaping box, wherein a water tank is embedded and fixed to the side walls of the shaping box and the base, a heating plate being installed on the outer wall of the water tank, and screws connected to the extrusion plates being threadedly inserted at both ends of the shaping box.

[0007] Preferably, both ends of the extrusion plate are in an arc-shaped structure, and a positioning rod that is slidably inserted into the shaping box is fixed to the outer wall of the extrusion plate.

[0008] Furthermore, a knob is fixed on the screw rod, and the screw rod is rotatably inserted into the extrusion plate through a bearing.

[0009] Furthermore, mounting plates are symmetrically fixed on the base, and the traction mechanism includes a driving shaft rotatably arranged between the two mounting plates and a winding roller fixedly sleeved on both ends of the driving shaft.

[0010] Furthermore, a motor is fixed to the side wall of the mounting plate, and the shaft of the motor is fixedly connected to the drive shaft.

[0011] Furthermore, the traction plate is in an L-shaped structure, and a plurality of connecting plates inserted into the PVC foam board body are fixed to the side wall of the traction plate.

[0012] Furthermore, a through hole is provided at the center of the connecting plate, and a fastening pin is provided in the PVC foam board body and is inserted into the through hole for damping.

[0013] Furthermore, a traction rope is wound around the winding roller, and a connecting seat is rotatably connected to the traction rope.

[0014] Furthermore, screw holes are symmetrically provided at the bottom end of the pulling plate, and the connecting seat is threadedly inserted into the screw holes.

[0015] The beneficial effects of the present invention are:

[0016] (1) The utility model is provided with a shaping box at the top of the base, and the base and the water storage tank on the shaping box heat and soften the PVC foam board body, and the PVC foam board body is shaped by the inner wall of the shaping box and the extrusion plate.

It is suitable for the extrusion shaping of PVC foam board bodies of different sizes, and is convenient for positioning the traction shaping of the PVC foam board body, thereby avoiding the PVC foam board body from becoming deformed after being heated and softened. After the heating plate heats the water in the water storage tank, the hot water heats the surface of the PVC foam board body, thereby avoiding the PVC foam board body from melting due to the excessive temperature of the heating plate.

[0017] (2) The utility model has a mounting plate symmetrically fixed on the side wall of the base, and a drive shaft is rotatably arranged on the mounting plate. When the PVC foam board body is towed, the connecting plate is inserted into it, and at the same time, the fastening pin passes through the top of the PVC foam board body and is inserted into the through hole with a damping function, so that the traction plate and the PVC foam board body are kept fixed, and the driving shaft is driven to rotate by the starting motor, and the winding roller rewinds the traction rope during the rotation, so that the traction plate drives the PVC foam board body to move, which is convenient for relocating the PVC foam board body and improving the convenience of transporting the PVC foam board body. The traction plate can be easily disassembled and replaced by unscrewing the connecting seat. BRIEF DESCRIPTION OF THE DRAWINGS
