Description

Technical Field

[0001] This utility model belongs to the technical field of circular wire extruders, and particularly relates to a circular wire extruder. Background Technology

[0002] A circular wire extruder is a mechanical device used to heat and melt polymer materials such as plastics and extrude them into circular wire products. It has many structural parts, and the die head is one of the components in a circular wire extruder.

[0003] The die head has orifices of a specific shape and size. Molten plastic is extruded through these orifices under pressure to form a circular filament. The diameter and shape of the orifices determine the thickness and cross-sectional shape of the filament. Traditionally, the die head is directly clamped to the machine body. Although this clamping method can ensure the stability between the die head and the machine body, in actual operation, the orifices inside the die head for material extrusion often become clogged due to material adhesion. Therefore, it is often necessary to disassemble and repair it. Sometimes, due to the high temperature inside the die head and its installation position, disassembly by hand is extremely inconvenient, affecting the ease and safety of disassembly and thus reducing the effectiveness of the equipment. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a circular wire extruder, which solves the problem that the existing equipment is not convenient to disassemble because the die head temperature is too high and the installation position is inconvenient.

[0005] This utility model is implemented as follows: a circular wire extruder includes a fixed frame applied to the machine body, on which a die head is movably attached via a snap-fit ​​component, and a rotating arm is fixedly connected to the fixed frame. It also includes:

[0006] An adjusting plate, which is slidably set inside the fixed frame, is used for adjusting the position of the die head;

[0007] A fixing component is installed between the adjusting plate and the rotating arm to limit the movement of the adjusting plate;

[0008] A rotating assembly, positioned between the adjusting plate and the die head, is used to adjust the angle of the die head, including a connector mounted on the die head.

[0009] In a preferred embodiment of this invention, the adjusting plate and the rotating arm are connected by a sliding assembly, which includes sliding grooves on both sides of the rotating arm, and a pulley that is slidably disposed in the sliding groove is installed on each side of the adjusting plate.

[0010] As a preferred embodiment of this invention, the fixing component includes a locking arm rotatably mounted on the rotating arm, and the locking arm is fixedly connected to the adjusting plate by a screw.

[0012] As a preferred embodiment of this invention, a guide groove is provided on the mold head, and two limiting rods that slide within the guide groove are fixedly provided on the lower side of the adjusting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention effectively drives the die head and locking components away from the machine body via an adjustment plate in the equipment, thereby creating a certain distance between the die head and locking components and facilitating the maintenance of the die head and locking components.

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, the present invention provides a circular wire extruder, including a fixed frame 1 applied on a machine body 2, a die head 3 movably connected to the machine body 2 via a snap-fit ​​component 4, a rotating arm 15 fixedly connected to the fixed frame 1, and further including:

[0025] An adjusting plate 5 is slidably set inside the fixed frame 1 for adjusting the position of the mold head 3;

[0026] A fixing component is provided between the adjusting plate 5 and the rotating arm 15 for limiting the position of the adjusting plate 5;

[0027] A rotating assembly, disposed between the adjusting plate 5 and the die head 3, is used to adjust the angle of the die head 3, including a connector 9 mounted on the die head 3.

[0028] As a preferred embodiment of this utility model, the adjusting plate 5 and the rotating arm 15 are connected by a sliding assembly, including a sliding groove 6 formed on both sides of the rotating arm 15, and a pulley 7 slidably disposed in the sliding groove 6 on each side of the adjusting plate 5 to maintain the sliding direction of the adjusting plate 5, while reducing the sliding resistance of the adjusting plate 5, making it more convenient to adjust the position.

[0029] As a preferred embodiment of this utility model, the fixing component includes a locking arm 8 rotatably mounted on the rotating arm 15. The locking arm 8 is fixedly connected to the adjusting plate 5 by a screw, which can effectively fix the adjusting plate 5, ensure the position of the adjusting plate 5, and prevent the adjusting plate 5 from sliding when the mold head 3 is fixed to the machine body 2, thereby affecting the connection stability between the mold head 3 and the machine body 2.

[0030] As a preferred embodiment of this utility model, the rotating assembly also includes a drive motor 10 mounted on the adjusting plate 5. A reduction gearbox 11 is mounted on the output end of the drive motor 10, and a universal joint 12 is mounted on the output end of the reduction gearbox 11. The end of the universal joint 12 is located in the connector 9, which facilitates the driving of the mold head 3 to swing, thereby facilitating the maintenance, cleaning and replacement of the mold head 3.

[0031] As a preferred embodiment of this utility model, a guide groove 13 is provided on the mold head 3, and two limiting rods 14 that slide in the guide groove 13 are fixedly provided on the lower side of the adjusting plate 5, making it more convenient for the mold head 3 to rotate and avoiding the situation of tilting when the mold head 3 rotates.

[0032] The working principle of this utility model:

[0033] refer to Figure 1 and Figure 2The die head 3 is movably attached to the machine body 2 via the snap-fit ​​component 4. Through the operation inside the machine body 2, the material is conveyed to the die head 3 and extruded. Since the machine body 2 is existing technology, it will not be described in detail here.

[0034] When the mold head 3 needs maintenance, the locking piece 4 is separated from the machine body 2, and at the same time... Figure 3 The locking arm 8 is disassembled. Specifically, the screws on the locking arm 8 are separated from the rotating arm 15. At this time, the adjusting plate 5 is separated from the rotating arm 15. Then, the adjusting plate 5 is pulled and slid on the rotating arm 15. Figure 5 and Figure 4 The pulley 7 slides in the groove 6, causing the adjusting plate 5 to gradually move away from the machine body 2. When the adjusting plate 5 moves away from the machine body 2, the mold head 3 drives the locking piece 4 to move away from the machine body 2 at the same time. When the adjusting plate 5 moves away to a certain distance, the drive... Figure 5 When the drive motor 10 is working, it drives the reduction gearbox 11 to decelerate when the drive motor 10 rotates in the forward direction. At the same time, the reduction gearbox 11 drives the universal joint 12 to rotate. When the universal joint 12 rotates, it drives the connector 9 to rotate the mold head 3. This causes the snap-fit ​​part 4 on one side of the mold head 3 to deflect towards the side of the rotating arm 15. When the snap-fit ​​part 4 deflects to a certain position, the drive motor 10 stops working. At this time, the mold head 3 and the snap-fit ​​part 4 can be inspected and replaced, thus ensuring convenient replacement. This avoids the impact of excessive temperature of the mold head 3 and the close distance between the mold head 3 and the machine body 2 on replacement and inspection. After the mold head 3 and the snap-fit ​​part 4 are inspected and repaired, the drive motor 10 can be reversed to reset the mold head 3 and the snap-fit ​​part 4. Then, the sliding adjustment plate 5 can be used to snap the snap-fit ​​part 4 back into the machine body 2, allowing the equipment to work again.

[0035] This invention effectively drives the mold head 3 and the snap-fit ​​component 4 away from the machine body 2 through the adjustment plate 5 in the equipment, thereby creating a certain distance between the mold head 3 and the snap-fit ​​component 4 and the mold head 3, which facilitates the maintenance of the mold head 3 and the snap-fit ​​component 4. Furthermore, by driving the rotating component, the angle of the mold head 3 and the snap-fit ​​component 4 can be effectively changed, so that the mold head 3 and the snap-fit ​​component 4 will not be too hot during maintenance, or affected by the machine body 2, thus preventing the maintenance and replacement from being inconvenient. This further improves the maintenance and replacement efficiency of the equipment and makes the equipment more convenient to use.
