Abstract
Description
Technical Field
[0001] This application relates to the field of plastic extrusion molding technology, and in particular to an extruder head for die-casting pallet blanks. Background Technology
[0002] Waste plastic extrusion die casting technology is an important method for recycling urban waste plastics. Waste plastic is melted and recast using a press to obtain usable pallet products. However, the extruded blanks are thick and wide, making them difficult to cut. The cut blanks also vary in size and quality, resulting in low cutting efficiency. Therefore, there is an urgent need for a high-speed cutter specifically designed for pallet blanks to solve these problems. Summary of the Invention
[0003] The purpose of this invention is to provide a die-casting pallet blank extruder head to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this application adopts the following technical solution:
[0005] This application provides a die-casting pallet blank extruder head, including an extrusion die head connected to an extruder. The extrusion die head has a pair of dies and a distribution channel inside. A narrow material extrusion port is located between the pair of dies. A pair of mounting plates are connected to the left and right sides of the front of the extrusion die head. A cylinder is fixedly connected between the pair of mounting plates. The cylinder has a slide rod parallel to the material extrusion port, and one or more cylinder sliders are slidably connected to the slide rod. A pair of pressure plates are connected to the cylinder sliders, and a blade is fixed between the pair of pressure plates.
[0006] In one possible implementation, a plurality of cylinder sliders are slidably fitted on the slide rod, and the stroke of the cylinder is less than the distance between two adjacent pressure plates.
[0007] In one possible implementation, the mounting plate has a horizontal portion extending horizontally and a vertical portion perpendicular to the horizontal portion, and the cylinder is mounted on the vertical portion.
[0008] In one possible implementation, the material extrusion port faces forward, and the blade is perpendicular to the extrusion direction of the material extrusion port.
[0009] In one possible implementation, the surface of the blade has an anti-stick coating.
[0010] In one possible implementation, the anti-stick coating is a polytetrafluoroethylene coating.
[0011] The beneficial effects of this utility model are as follows: the extruder head has a compact and simple structure, is easy to install, works efficiently, and the cutting process is stable and reliable, which facilitates the subsequent die casting and molding of the blank.

[0016] To illustrate the technical content, structural features, achieved objectives, and effects of this application in detail, the technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of this application. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of an exemplary embodiment may be used or implemented in another exemplary embodiment without departing from the inventive concept.
[0017] In the description of this application, unless otherwise stated, "a plurality of" means two or more. Furthermore, in this application, spatial relative terms such as "above," "on," "above," "higher," and "side" (e.g., in "left side," "right side") are used to describe the relationship between one element and another (other) element as shown in the figures. Spatial relative terms are intended to include different orientations of the device in use, operation, and / or manufacture other than those depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "under" other elements or features would then be positioned "above" said other elements or features.
[0018] See Figure 1As shown, this application provides a die-casting pallet blank extruder head, including an extrusion die head 1 connected to an extruder, wherein the extrusion die head 1 has a pair of dies 9. The extrusion die head 1 has a distribution channel inside, and there is a narrow material extrusion port between the pair of dies 9. The material extrusion port faces forward, so the material moves forward after extrusion. When a movable receiving platform is used to receive the material, the extruded material can be spread flat on the receiving platform.
[0019] See Figure 2 , 3 As shown, a pair of mounting plates 2 are connected to the left and right sides of the front part of the extrusion die 1, respectively. The mounting plate 2 has a horizontal part 5 extending horizontally and a vertical part 6 perpendicular to the horizontal part 5. A cylinder 7 is fixedly connected between the vertical parts 6 of the pair of mounting plates 2.
[0020] See Figure 2 As shown, the cylinder 7 has a slide rod 10 extending in a left-right direction, which is also parallel to the material extrusion port. Multiple cylinder sliders 8 are slidably connected to the slide rod 10. A pair of pressure plates 3 are connected to each cylinder slider 8, and a blade 4 is fixed between the two pressure plates 3. The blade is clamped between the two pressure plates 3, and the pressure plates 3 press against each other to clamp the blade 4, thereby fixing the blade 4. The blade 4 has sharp edges on both sides.
[0021] Furthermore, the stroke of the cylinder 7 should be less than the distance between two adjacent pressure plates 3. By employing a multi-blade cutting structure, the entire blank can be cut quickly with a relatively short cylinder stroke.
[0022] In one possible implementation, the material extrusion port faces forward, and the blade 4 is perpendicular to the extrusion direction of the material extrusion port, so that the material blank can be cut vertically.
[0023] To prevent the extruded material from sticking to the blade surface during high-temperature extrusion, the blade 4 also has an anti-stick coating. In one possible implementation, the anti-stick coating is a polytetrafluoroethylene (PTFE) coating.
[0024] Furthermore, the mounting plate 2 is connected to the extrusion die 1 by bolts, and one end of the mounting plate 2 is attached to the surface of the extrusion die 1 and fixed by bolts, while the other end is connected to the cylinder 7 for fixation. The cylinder 7 is parallel to the extrusion die 1 and is located at the discharge port of the extrusion die 1.
[0025] During operation: When the blank needs to be cut, the cylinder works by inlet or outlet of air to push the cylinder slider to the left or right, thereby driving the blade to cut the blank at the extrusion die outlet, completing the entire cutting process of the blank.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the inventive spirit and scope. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
