Description

Technical Field

[0001] This utility model relates to the field of thermoplastic tube extrusion molding, and in particular to a tube extrusion molding die head. Background Technology

[0002] As is well known, extrusion molding, also known as plastic extrusion, is a versatile, widely used, and prevalent processing method in the field of thermoplastic material processing. Extrusion molding involves conveying, compressing, melting, and plasticizing plastic between a rotating screw and barrel, and then quantitatively passing it through a die and shaping device at the extruder head to produce continuous profiles. Tube forming typically requires a tube extrusion molding die. The prior art CN 220095470 U discloses a pipe extrusion molding die head, which can intuitively show which part of the extruded tube has uneven material output, facilitating quick adjustment of the die head and improving debugging efficiency. The die head includes an extrusion head at the front end, a flow divider inside the die head, several adjusting screws on the side wall of the die head, a sleeve installed on the outside of the extrusion head, several flow channels at the front of the sleeve, and several drive rods on the side wall of the sleeve. The number of flow channels is the same as the number of adjusting screws. The outer wall of the extrusion head has external threads, and the inner wall of the sleeve has internal threads. The sleeve and the extrusion head are connected by threads. Each drive rod is equipped with a heat insulation sleeve.

[0003] Although the aforementioned patent document uses the length of material flowing out from several channels to determine the discharge situation and make adjustments, the patent design has a flaw. The material extruded in the channels first converges between the extruder head and the channels, filling the entire extruder head and sleeve before flowing out from the channels. As a result, judging or adjusting the positional relationship based on the length of material flowing out from the channels is not accurate. Utility Model Content

[0004] One objective of this invention is to provide a pipe extrusion molding head that at least solves any of the above-mentioned technical problems.

[0005] A further objective of this invention is to prevent material from converging and being squeezed between the extruder head and the flow channel, thus affecting the judgment length.

[0006] Another further objective of this invention is to improve the initial discharge effect, observe different areas, and improve the efficiency of judgment.

[0007] In particular, this utility model provides a pipe extrusion molding die head, including an extrusion head, wherein a flow divider is provided inside the extrusion head; A sleeve is disposed at the discharge port of the extrusion head, and the sleeve includes a cylindrical body, the cylindrical body of which is provided with a partition plate.

[0008] Furthermore, the cross-section of the partition plate is cross-shaped.

[0009] Furthermore, a corresponding cross-shaped blade is provided between the partition plate and the diverter.

[0010] Furthermore, the cross-section of the partition plate is shaped like a star.

[0011] Furthermore, a corresponding cross-shaped blade is provided between the partition plate and the diverter.

[0012] Furthermore, a drive rod is provided on the outer periphery of the cylinder, and the drive rod is arranged in a circular array with the cylinder as the center.

[0013] Furthermore, the surface of the partition plate is provided with a coating.

[0014] The technical effects and advantages of this utility model are as follows: This invention utilizes multiple equally divided and intersecting partition plates within the sleeve for segmentation. Corresponding equally divided blades, such as cross blades or star-shaped blades, are positioned between the partition plates and the distributor of the extruder head. These equally divided blades divide the material extruded by the distributor into equal portions. As the extruder head continuously extrudes and pushes the material out, it becomes clear whether the length and thickness of each extruded portion are consistent. This allows for adjustment of the extruder head based on the output of each portion. After adjustment, when the extruder head is rotated and removed, the cross blades can directly grind and cut off the excess material, eliminating the need for specialized grinding with a cutting tool.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a front view structural diagram of the present utility model. Figure 3 This utility model Figure 2 Schematic diagram of the cross-sectional structure along the AA direction.

[0021] The solution in this embodiment provides a pipe extrusion molding die head, such as... Figure 1-3 As shown, it includes an extrusion head 1 and a sleeve 2. The extrusion head 1 is provided with a flow divider 3. The sleeve 2 is located at the discharge port of the extrusion head 1 and includes a cylinder 202. The cylinder 202 is provided with a partition plate 203. The cross-section of the partition plate 203 is cross-shaped. A corresponding cross blade 2031 is provided between the partition plate 203 and the flow divider 3. The cross blade 2031 is used to cut the extrusion can body. At the same time, the thrust during extrusion pushes the cut tube body to move, so that the uniformity of the output can be observed according to the length and thickness of the output material.

[0022] Example 2 It should be further explained that the cross-section of the partition plate 203 is in the shape of a star. By setting multiple partition plates 203, it is possible to more accurately determine which part has uneven thickness and uneven material output.

[0023] It should be further explained that a corresponding cross-shaped blade 2031 is provided between the partition plate 203 and the diverter 3, and the blade 2031 is used for partition cutting.

[0024] It should be further explained that a drive rod 201 is also provided on the outer periphery of the cylinder 202, and the drive rod 201 is arranged in a ring array with the cylinder 202 as the center.

[0025] It should be further noted that the surface of the partition plate 203 is provided with a coating, which is polytetrafluoroethylene.

[0026] Working principle of this utility model: In use, the material is divided by multiple equally divided and intersecting partition plates 203 inside the sleeve 2. At the same time, corresponding equally divided blades 2031, such as cross blades 2031 or star blades 2031, are set between the partition plates 203 and the distributor 3 of the extruder head 1. The equally divided blades 2031 divide the material extruded by the distributor 3 into equal parts. As the extruder head 1 continuously squeezes and sends out the material, the material is continuously pushed out. At the same time as pushing out, it can be clearly seen whether the length and thickness of each part of the material being extruded are consistent. Thus, the extruder head 1 can be adjusted according to the output of each part. After adjustment, when the extruder head 1 is rotated and removed, the cross blades 2031 can directly grind and cut off the excess material that has been extruded, without the need for special grinding with a knife.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
