A pvc composite film plate production device

Abstract

The invention relates to a production device for PVC composite film board, which includes a track and a raw material mixing device, and the raw material mixing device is arranged in front of the track; device, a cooling roller table, a roller temperature machine, a traction device, a sheet material dividing device, and a sheet material stacking device; the calendering compound device includes a calender and a composite film continuous splicing guide system. Through the composite film continuous connection guide system of the present invention: the continuous connection function of the composite film continuous connection device and the pressing function of the composite film tension device reduce the burden on the staff to replace and calibrate the composite film on the calender, greatly improving safety ;The composite film is automatically spliced, and there is no need to stop and restart the calender, which reduces the waste of energy and materials and improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of thermoplastic product preparation, in particular to a PVC composite film board production device. Background technique [0002] The main component of PVC is polyvinyl chloride, which is light yellow, translucent and shiny. P V C , the full name is Polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. It is the second most used synthetic material worldwide. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption average 1.4 million tons. PVC is being produced and applied all over the world a...

Problems solved by technology

[0003] PVC sheet is now a hot product. In the production of PVC sheet, it is necessary to press the composite film (patterned film and protective film) onto the PVC bottom plate. During this process, the PVC bottom plate is produced by an extruder. The existing technology It is possible to continuously extrude the PVC bottom plate. However, the composite film (patterned film and protective film) is basically a roll of film, which needs to be replaced in time after it is exhausted. This replacement process is not only difficult but also consumes a lot of working time. , it is often necessary to stop the work of the calender, so that the temperature of the calender roll is lowered to replace the composite film (patterned film and protective film), which greatly reduces the production efficiency
