Description

Technical Field

[0001] This utility model relates to the technical field of cable processing equipment, and in particular to a vacuum pumping device for the extruder head. Background Technology

[0002] Extruders play a vital role in modern industrial production, widely used in industries such as cables and plastics. Extruder vacuuming, a common process operation, has many important functions. As a crucial process, extruder vacuuming plays an irreplaceable role in extrusion production. By removing gases from materials, improving material flowability, saving energy, and increasing product density and strength, extruder vacuuming helps improve product quality and reduce production costs, making it an indispensable key technology in modern industrial production.

[0003] However, existing extruders only have a vacuuming device installed, which cannot guarantee a good vacuuming effect because some air will enter from the extruder's inlet, thus affecting the quality of the vacuuming. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum device for the extruder head, which solves the technical problem that excessive air easily enters during vacuuming of the extruder in the prior art.

[0005] This application discloses a vacuum pumping device for the extruder head, comprising:

[0006] Extruder;

[0007] A sleeve, wherein a wire channel is provided inside the sleeve, and one end of the sleeve is threadedly connected to the die head of the extruder;

[0008] A vacuum fan, wherein the vacuum fan is connected to the sleeve;

[0009] A windbreak mechanism is provided at the end of the wiring channel;

[0010] A line stabilizing mechanism is installed at the end of the sleeve away from the extruder, and the line stabilizing mechanism is located outside the windbreak mechanism.

[0011] This application designs a vacuum blower with a wind-blocking mechanism installed at the end of the blower head to reduce the amount of air entering the blower head. Then, a cable stabilizing mechanism is used to prevent the cable from swaying, thereby improving the processing quality of the cable.

[0012] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0013] Furthermore, the free end of the sleeve is trumpet-shaped;

[0014] The windbreak mechanism includes:

[0015] Multiple wind deflectors are installed at the ends of the cable routing channel, and the wind deflectors are combined to form a horn shape that is wider on the outside and narrower on the inside;

[0016] The locking bolt passes through the sleeve and connects to the wind baffle. The advantage of this step is that the wind baffle can complete the wind-blocking operation, preventing air from entering the extruder during vacuuming.

[0017] Furthermore, the windproof component is a rubber baffle. The beneficial effect of this step is that the rubber baffle can block the wind while preventing damage to the cable.

[0018] Furthermore, the end of the windbreak extends into the wiring channel. The beneficial effect of this step is that the windbreak effect can be further improved through the design of the windbreak position.

[0019] Furthermore, a cleaning sponge is installed inside the sleeve, and the cleaning sponge cooperates with the wiring channel.

[0020] Furthermore, the stabilizing mechanism is a grid-shaped guide wheel mechanism. The beneficial effect of this step is that the grid-shaped guide wheel mechanism can effectively ensure the stability of the cable during extrusion.

[0021] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0022] 1. By setting up a windbreak mechanism and a wire stabilizing mechanism, this application can reduce the amount of air entering the machine head during vacuuming, thereby improving the processing quality of cable products.

[0023] 2. This application designs the structure of the windbreak mechanism, which, through the rubber components, not only protects the cable but also further reduces the entry of air, thereby improving the quality of the cable. Attached Figure Description

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0034] Example:

[0035] like Figure 1-2 As shown in the figure, this application discloses a vacuum device for the extruder head to realize vacuum operation. At the same time, the air inlet of the vacuum device is designed so that it can wrap the wire core during vacuuming, thereby ensuring product quality. That is, it can remove gas from the material, improve the fluidity of the base material, save energy and reduce production costs.

[0036] The specific structure of this application includes:

[0037] The extruder 1 has a sleeve installed at its die head. The semi-finished cable enters the extruder die head at a linear velocity F and exits through the cable passage 3 of the sleeve 2. After subsequent vacuuming, the viscosity of the molten material can be reduced, thereby improving the quality of the product. Specifically, this extruder is an existing extruder.

[0038] Sleeve 2, the sleeve 2 is provided with a wire channel 3 inside, and one end of the sleeve 2 is threadedly connected to the die head of the extruder 1, which facilitates the assembly of the sleeve 2, that is, the connection is made by threaded connection;

[0039] Vacuum blower 4 is connected to sleeve 2. The vacuum blower 4 can perform vacuuming, that is, vacuuming the die head area, so that the extruder 1 forms negative pressure, thereby reducing the gas in the material and helping to ensure product quality.

[0040] The windbreak mechanism 5 is located at the end of the cable routing channel 3. The windbreak mechanism 5 achieves the effect of blocking, that is, preventing air from entering the machine head from the cable routing channel opening and entering the machine head, thus affecting the extrusion effect.

[0041] The cable stabilizing mechanism 6 is installed at the end of the sleeve 2 away from the extruder 1, and the cable stabilizing mechanism 6 is located outside the windproof mechanism 5. The cable stabilizing mechanism 6 can stabilize the cable, that is, ensure the cable can exit in the correct direction, and at the same time, prevent shaking, which would affect the windproof mechanism 5 and thus affect the windproof effect of the windproof mechanism 5.

[0042] In order to improve the wind-blocking effect, this application designs a wind-blocking mechanism, specifically, the free end of the sleeve 2 is trumpet-shaped;

[0043] The windbreak mechanism 5 includes:

[0044] Multiple wind deflectors 501 are installed at the end of the cable routing channel 3. The wind deflectors 501 are combined to form a horn shape that is wider at the outside and narrower at the inside. The wind deflectors 501 are mainly used to block the end of the cable routing channel of the machine head to prevent air from entering from the cable routing channel 3 when vacuuming.

[0045] A locking bolt 502 passes through the die head of the extruder 1 and connects to the windshield 501. The locking bolt 502 is used to fasten the windshield 501, ensure the stability of the windshield 501 assembly, and enable the windshield 501 to wrap the cable.

[0046] Because the cable needs to enter and exit through the flared opening formed by the wind deflector 501, specifically, the wind deflector 501 is a rubber baffle, this can prevent the cable from being damaged.

[0047] To further ensure the vacuuming effect, the end of the windproof member 501 described in this application extends into the wiring channel 3, which can further block the wiring channel and thus improve the windproofing effect.

[0048] In order to improve the extrusion quality, the sleeve 2 in this application is equipped with a wiping sponge 7, which cooperates with the wiring channel 3.

[0049] Specifically, the cable stabilizing mechanism 6 described in this application is a grid-shaped guide wheel mechanism. The grid-shaped guide wheel mechanism includes a mounting frame and multiple rollers. The multiple rollers form a grid shape, that is, the cable passes through the middle. In this way, the roller shafts limit the movement and ensure that the cable can pass through stably, thereby improving the processing quality of the cable.

[0050] This application utilizes vacuuming in an extruder to effectively remove gases from the material. During extrusion, air or other gases often become mixed in with the raw material, potentially causing defects such as bubbles and pores, which affect the quality of the final product. Vacuuming completely removes these gases, ensuring the purity of the material and improving product quality.

[0051] Secondly, vacuuming in an extruder can improve material flowability. During extrusion, the raw material needs to be continuously heated inside the barrel to reach a molten state, and then formed into the desired product shape through a die. If residual gas or impurities remain in the material, it will affect its flowability, resulting in an uneven product surface or a porous structure. Vacuuming effectively reduces the presence of impurities and air, improves material uniformity and flowability, and ensures the quality of the formed product.

[0052] In addition, vacuuming the extruder helps save energy and reduce production costs. During extrusion, the presence of a large amount of gas in the material increases the viscosity of the molten material, requiring the machine to consume more energy to complete the extrusion operation.

[0053] Further explanation regarding this application:

[0054] This application designs a vacuuming device, which uses a vacuum blower to perform vacuuming at the head of the extruder 1. In order to ensure the vacuuming effect, this application also provides a pressure gauge, which is specifically installed on the sleeve to monitor the vacuuming effect.

[0055] During cable production, the cable semi-finished product enters the extruder head at a linear speed F. By using a vacuum fan, a vacuum treatment is performed on the sleeve 2, creating a negative pressure inside the sleeve 2. Adjusting the locking bolt causes the wind baffle 501 to wrap around the cable semi-finished product inward along the wire feeding direction, thereby achieving a negative pressure and vacuum state inside the sleeve 2.

[0056] By removing these gases through vacuuming, the viscosity of the molten material can be reduced, thus reducing the energy consumption of extruder 1 during operation, thereby achieving energy savings and reducing production costs.
