Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of geomembrane production equipment, in particular to a die head for the calendering and forming of geomembranes. Background Art
[0002] A geomembrane is a waterproof barrier material with high molecular polymer as the basic raw material, which is widely used in construction projects as a waterproof and toughening material. Geomembranes can be divided into blow molding process and calendering process according to different production and manufacturing methods. Among them, the geomembrane produced by the calendering process is the calendered geomembrane. The surface of the calendered geomembrane is bright and relatively smooth, and the production speed is relatively fast. During production, first, raw materials such as polyethylene particles, moisture-proof agents, color masterbatches, and carbon black are mixed in a certain proportion. After the raw materials are stirred evenly, they are added to the silo, and then the polyethylene and other granular materials are heated and melted into a fluid state by an extruder, passed through the die head, and then cooled and formed by a cooling roller with a coolant added. The width of the existing die head for calendered geomembranes is fixed, and only geomembranes of a single width specification can be produced. Each width specification of geomembrane requires a separate set of die heads, resulting in a relatively high production cost investment. In addition, the length of the existing die head is fixed, and the flow channels inside the die head are fixed, making it impossible to modify the existing die head. In view of the problems in the prior art, we propose a die head for the calendering and forming of geomembranes. Content of the Utility Model
[0003] The utility model aims at the above problems in the prior art and provides a die head for the calendering and forming of geomembranes, which is achieved through the following technical solutions:
[0004] A die head for the calendering and forming of geomembranes includes a support plate. A forming component is arranged on one side of the support plate, and a cutting component is arranged on the other side. The forming component includes two rotatable rollers arranged in parallel. The two ends of the support plate are respectively fixedly connected with first support plates, and the rotatable rollers are rotatably connected between the two first support plates. The two rotatable rollers rotate towards each other. The cutting component includes a second support plate, and the second support plates are respectively fixedly connected to the two ends of the support plate. A first support shaft is fixedly connected between the two second support plates. Two groups of support rods are slidably connected to the first support shaft. One end of each support rod is fixedly connected with a sliding sleeve, and the other end is rotatably connected with a cutting knife. The sliding sleeve is sleeved on the first support shaft, and a fastening bolt is threadedly connected to the side wall of the sliding sleeve. One end of the fastening bolt abuts against the first support shaft. The axis of the rotation shaft of the cutting knife is parallel to the axis of the first support shaft, and the cutting knife abuts against the side wall of one of the rotatable rollers.
[0005] The utility model is further arranged as follows: The first support shaft is marked with dimension lines.
[0006] The present utility model is further configured such that: a second support shaft is fixedly connected between the two second support plates, the second support shaft is arranged parallel to the first support shaft, a clamping groove is formed on the support rod, and the second support shaft is clamped in the clamping groove.
[0007] In summary, the beneficial technical effects of the present utility model are:
[0008] The forming width of the geomembrane is controlled by two cutting knives. During production, the distance between the two cutting knives can be adjusted according to different width requirements of the geomembrane. One set of die heads can meet the production of geomembranes with different width requirements, thereby reducing the number of mold openings and reducing the production cost of enterprises.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0013] Embodiment
[0014] As Figure 1-2As shown in the figure, a die head for plastic coating forming of geomembrane disclosed by the present utility model includes a fixing plate 1. A forming component is arranged on one side of the fixing plate 1, and a cutting component is arranged on the other side thereof. The forming component includes two rotatable rollers 2 arranged in parallel. Two ends of the fixing plate 1 are respectively fixedly connected with first support plates 3. The rotatable rollers 2 are rotatably connected between the two first support plates 3. The two rotatable rollers 2 rotate towards each other. The cutting component includes second support plates 4. The second support plates 4 are respectively fixedly connected to two ends of the fixing plate 1. A first support shaft 5 is fixedly connected between the two second support plates 4. The axis of the first support shaft 5 is parallel to the axis of the rotatable rollers 2. Two groups of support rods 6 are slidably connected to the first support shaft 5. One end of the support rod 6 is fixedly connected with a sliding sleeve 7, and the other end thereof is rotatably connected with a cutting knife 8. The sliding sleeve 7 is sleeved on the first support shaft 5. A fastening bolt 9 is threadedly connected to the side wall of the sliding sleeve 7. One end of the fastening bolt 9 abuts against the first support shaft 5 for fixing the sliding sleeve 7 on the first support shaft 5. The rotation axis of the cutting knife 8 is parallel to the axis of the first support shaft 5. The cutting knife 8 abuts against the side wall of one of the rotatable rollers 2. Before the plastic-coated geomembrane is formed, according to the width required for the formation of the geomembrane, the distance between the two cutting knives 8 is adjusted so that the forming width of the geomembrane meets the production requirements. This die head meets the forming requirements of geomembranes with different widths, thereby reducing the number of mold openings and reducing the input of enterprise costs. During production, the material melted into a fluid state by an extruder falls between the two rotatable rollers 2. The two rotatable rollers 2 rotate towards each other. The material is extruded and adhered to the side walls of the rotatable rollers 2. The two cutting knives 8 rotate along with the rotatable roller 3 to cut the material into the required width, and then one end of the material adhered to the rotatable roller 2 is sequentially passed through mechanisms such as a cooling roller in existing equipment for cooling and forming. In order to facilitate the adjustment of the distance between the two cutting knives 8, the first support shaft 5 is marked with a scale line 10.
[0015] A second support shaft 11 is fixedly connected between the two second support plates 4. The second support shaft 11 is arranged parallel to the first support shaft 5. A clamping groove 12 is formed on the support rod 6. The second support shaft 11 is clamped in the clamping groove 12. The second support shaft 11 mainly serves to support the geomembrane material coming out between the two rotatable rollers 2. In addition, the second support shaft 11 plays a role in limiting the support rod 6.
[0016] The driving mode of the two rotatable rollers adopts the same driving mode as that of the cooling roller in the prior art (not shown in the figure).
