Abstract
Description
Technical Field
[0001] This utility model belongs to the field of foaming technology, specifically relating to a secondary foaming production line. Background Technology
[0002] Foaming is the process of creating a microporous structure in plastics. Almost all thermosetting and thermoplastic plastics can be made into foamed plastics. Commonly used resins include: polystyrene resin, polyurethane resin, polyvinyl chloride resin, polyethylene resin, urea-formaldehyde resin, phenolic resin, etc.
[0003] Currently used foaming production lines typically rely on manual handling and transmission of the extruded sheets, which is time-consuming, labor-intensive, and inefficient. Utility Model Content
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a secondary foaming production line that can automatically transfer materials and increase production efficiency.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a secondary foaming production line, including a mixer, an elevator, an extrusion tableting mill, a first vertical open mill, a second vertical open mill, a slicer, and a slicer. The mixer, elevator, extrusion tableting mill, first vertical open mill, second vertical open mill, slicer, and slicer are arranged and connected in sequence. The first vertical open mill includes a base and two hollow rollers. The two hollow rollers are mounted on the base and rotate up and down. A first material guide module is attached to the hollow rollers.
[0006] The machine base has conveying components on both sides between the two hollow rollers.
[0007] The surface of the hollow roller is electroplated with a hard chrome layer.
[0008] The output port of the extrusion tablet press is equipped with an electric roller, and a second material guiding module is attached to the electric roller.
[0009] The surface of the electric roller is electroplated with a hard chrome layer.
[0010] A conductive cooling line is also provided between the vertical open mill and the slicer.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This utility model discloses a secondary foaming production line. During production, the sheet material is mixed in an internal mixer, then conveyed to an extrusion tableting machine via an elevator for extrusion. The sheet material is further mixed and conveyed by a first vertical open mill and a second vertical open mill. Finally, the sheet material is cut and stacked by a slicer and a sheet collecting machine, achieving automatic conveying and increasing production efficiency. Attached Figure Description

[0018] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.
[0019] like Figures 1-4 As shown, this embodiment provides a secondary foaming production line, including a mixer 1, an elevator 2, an extrusion tablet press 3, a first vertical open mill 4, a second vertical open mill 14, a slicer 5, and a slicer 6. The mixer 1, elevator 2, extrusion tablet press 3, first vertical open mill 4, second vertical open mill 14, slicer 5, and slicer 6 are arranged sequentially and connected. The first vertical open mill 4 includes a base 7 and two hollow rollers 8, which are mounted on the base 7 and rotate vertically. A first guide module 9 is attached to the hollow rollers 8. Specifically, the base 7 has conveying components 10 on both sides between the two hollow rollers 8. The slicer includes a heating roller with a cutter mounted on it. The structure of the second vertical open mill 14 is the same as that of the first vertical open mill 4. During production, the material is internally mixed using a mixer 1, then conveyed to an extrusion sheeter 3 via a hoist 2 for extrusion. The sheet is further processed and conveyed by a first vertical open mill 4 and a second vertical open mill 14. Finally, it is cut and stacked by a slicer 5 and a sheet receiver 6, achieving automated conveying and increasing production efficiency. A first guide module 9 effectively prevents the material from sticking to the rollers. Furthermore, water is circulated through the two hollow rollers 8 to maintain a constant temperature.
[0020] Furthermore, the surface of the hollow roller 8 is electroplated with a hard chrome layer, which makes the surface of the hollow roller 8 less prone to rusting.
[0021] Furthermore, the output port of the extrusion tablet press 3 is equipped with an electric roller 11, and a second material guide module 12 is attached to the electric roller 11. Specifically, the surface of the electric roller 11 is electroplated with a hard chrome layer. The sheet is extruded and transported through the electric roller 11 and the second material guide module 12.
[0022] Furthermore, a conductive cooling line 13 is provided between the vertical open mill 4 and the slicer 5. Specifically, the conductive cooling line includes a transmission belt, multiple guide rods, and multiple drive wheels. The transmission belt is placed on the multiple guide rods and multiple drive wheels, and the drive wheels are placed between adjacent guide rods. The diameter of the drive wheels is larger than the diameter of the guide rods. The extruded sheet is driven through the conductive cooling line 13 and cooled to room temperature.
[0023] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
