Description

Technical Field

[0001] This utility model relates to the field of inline feeding technology for duct extrusion, specifically to an inline feeding device for duct extrusion. Background Technology

[0002] A car door trim is a decorative component inside a car door, typically used to cover the inside of the door to improve the comfort and aesthetics of the interior. The name "tweed trim" comes from the material it is made of – wool, a high-end velvet fabric. When this fabric is mixed with rubber, the resulting trim not only has good sealing properties but also a better feel and is softer.

[0003] Existing extrusion equipment for fabric grooves often suffers from uneven mixing or clogging of the discharge port due to the use of multiple materials during the feeding process. Furthermore, the molds require various die head designs for easy replacement and use. For example, Chinese Patent Publication No. CN220904057U discloses a door fabric groove mold with a sliding material auxiliary function, comprising a feeding module and a forming module. The feeding module includes a skeleton feeding mandrel and a fluid feeding unit. The skeleton feeding mandrel has a skeleton channel, and the fluid feeding unit has a main channel, a secondary channel, and a sliding material channel. The forming module includes a first forming plate, a second forming plate, and a third forming plate. The first forming plate has a primary forming channel, a sliding material transition channel, and a primary distribution channel; the second forming plate has a secondary forming channel and a secondary distribution channel; and the third forming plate has a through-type final forming channel. The door groove mold described above can complete the addition of the sliding material while extruding, which has the advantages of convenient processing and high efficiency. In this solution, the mold needs to be installed on the extrusion equipment and multiple models need to be designed for use when extruding products.

[0004] Therefore, it is necessary to invent a trough extrusion device to solve the above problems. Utility Model Content

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figures 1-5 The device shown is a fabric extrusion line feeding device, including a main body 1, a drive mechanism 2, a feeding mechanism 3, a feeding hopper 301, a distribution hopper 4, a heating mechanism 6, an extrusion head 7, and a quick-release die head 8. The drive mechanism 2 is installed inside the main body 1. A auger conveyor rod 201 is connected to the drive mechanism 2 via a motor. A linkage shaft 202 is connected to the auger conveyor rod 201 via a sprocket. The linkage shaft 202 extends into the feeding mechanism 3. A distribution hopper 4 is installed at the top of the feeding mechanism 3. Multiple hooks 5 are installed on the edge of the distribution hopper 4. The hooks 5 are fixed to through holes on an external material conveying pipe. The bottom of the feeding mechanism 3 is connected through the feeding hopper 301. 01 The material is conveyed to the surface of the auger conveyor rod 201. The end of the auger conveyor rod 201 is sleeved in the heating mechanism 6 through a metal pipe. The end of the heating mechanism 6 is provided with an extrusion head 7. A quick-release mold head 8 is connected to the extrusion head 7 by a plug-in method. A shaping clamp 9 is placed on the quick-release mold head 8. The shaping clamp 9 is an elastic mechanism. The shaping clamp 9 can arbitrarily clamp the surface of the extrusion head 7 or the quick-release mold head 8. The shaping clamp 9 is used to clamp the end of the rubber part extruded in the quick-release mold head 8. The shaping clamp 9 clamps the end of the rubber part until it is fixed to the traction mechanism or the take-up roller. When the shaping clamp 9 is not in use, it is clamped on the quick-release mold head 8.

[0018] The linkage shaft 202 is located at the connection between the feeding mechanism 3 and the distributing bin 4, and multiple limiting plates 204 are fixedly connected to the linkage shaft 202. The multiple limiting plates 204 are arranged in a ring array about the linkage shaft 202, and the bottom of the partition in the distributing bin 4 has space for the limiting plates 204 to rotate. A fixing ring 205 is fixedly sleeved in the middle of the linkage shaft 202, and a striking rod 206 is fixedly connected to the fixing ring 205. The end of the striking rod 206 can contact the elastic reset lever 401.

[0019] Elastic reset levers 401 are respectively installed on opposite sides of the two material distribution bins 4, and multiple elastic reset levers 401 are provided. The elastic reset levers 401 are connected to the side of the material distribution bin 4 through reset springs. The elastic reset levers 401 rotate after being propelled by an external force. When the external force is removed, the elastic reset levers 401 can be reset under the action of the reset springs. Multiple elastic reset levers 401 can contact the end of the striking rod 206. The elastic reset levers 401 are inverted E-shaped, and both ends of the elastic reset levers 401 can extend into the material distribution bin 4. The feeding mechanism 3 has a shape that is wider at the top and narrower at the bottom, and the upper part is fixedly connected to the two material distribution bins 4. The size of the upper part of the feeding mechanism 3 is nearly ten times the size of the bottom feeding bin opening 301. The heating mechanism 6 heats and melts the material conveyed by the auger conveyor rod 201 through a heating metal tube.

[0020] The working principle of this utility model is as follows: First, the required plastic material is connected through the independent channels separated by each partition in the multiple material distribution bins 4. The through holes on the edge of the channel pipes can be fixed with the hooks 5. After the material is conveyed in through the independent channels in the multiple material distribution bins 4, it is fed onto the surface of the auger conveyor rod 201 by the feeding mechanism 3 and continuously conveyed into the heating mechanism 6. After being heated and melted, it is extruded into the required shape from the extrusion head 7 and the quick-release die head 8. Different extrusion requirements for different groove shapes can be met by changing the quick-release die head 8 of different models and shapes. The rubber strip extruded from the quick-release die head 8 is clamped and fixed at the end of the shaping clamp 9. Often, the end that is just extruded is waste material and is not used. Alternatively, the end can be fixed to a distant winding mechanism or traction mechanism so that the rubber strip is continuously stretched out from the quick-release die head 8 and maintains a stable output.

[0021] To prevent material blockage and ensure uniform feeding during the feeding process, the continuous rotation of the auger conveyor rod 201 drives the rotation of the sprocket and linkage shaft 202, so that the rotation of the limit plate 204 evenly mixes the material inside the distribution bin 4 while preventing blockage. At the same time, the rotation of the linkage shaft 202 drives the rotation of the fixing ring 205 and the striking rod 206, which continuously strikes the elastic reset lever 401 to generate vibration, so that there is only one vibration force when the two distribution bins 4 feed material to the feeding mechanism 3, which improves the effect of preventing material blockage and uniform feeding.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
