Description

Technical Field

[0001] This application relates to the technical field of plastic processing equipment, and in particular to an extruder feeding structure. Background Technology

[0002] In various industries such as plastics processing, chemicals, food, and pharmaceuticals, extruders are widely used as essential production equipment in the continuous extrusion molding process of various materials. The feeding structure of the extruder, as its core component, plays a crucial role in improving production efficiency, ensuring product quality, and reducing energy consumption. However, traditional extruder inlet feeding structures still have some shortcomings in practical applications. Material may easily accumulate or clog at the inlet, which not only reduces production efficiency. Utility Model Content

[0003] In order to reduce extruder inlet blockage and improve extruder feeding efficiency and production efficiency, this application provides an extruder feeding structure.

[0004] The extruder feeding structure provided in this application adopts the following technical solution:

[0005] An extruder feeding structure includes a transition cylinder disposed on a feed inlet, a guide slope disposed on the inlet wall of the feed inlet, a vibrating plate disposed on the inner wall of the transition cylinder, the vibrating plate being connected to the inner wall of the transition cylinder via an elastic cover, a connecting rod disposed on the vibrating plate extending to the outside of the transition cylinder, and a vibration motor being connected to the connecting rod.

[0006] By adopting the above technical solution, a vibrating plate is installed on the inner wall of the transition cylinder, and an elastic cover is connected between the vibrating plate and the inner wall of the transition cylinder. This allows the vibrating plate to maintain a certain amount of movement during vibration, avoiding direct contact with the inner wall of the transition cylinder and thus preventing wear. A connecting rod is installed on the vibrating plate and extends to the outside of the transition cylinder. A vibration motor is connected to the connecting rod. Driven by the vibration motor, the vibrating plate vibrates inside the transition cylinder, thereby promoting the uniform distribution and flow of materials, reducing blockage at the extruder feed inlet, and improving the feeding efficiency and production efficiency of the extruder.

[0007] Optionally, one or more sets of vibrating plates are provided inside the transition cylinder, and each set of vibrating plates is arranged opposite to each other inside the transition cylinder, and the vibrating plates in the same set are connected by connecting rods.

[0008] By adopting the above technical solution, the vibrating plates in the same group are connected by a connecting rod to enhance the vibration effect and allow the material to flow more smoothly in the transition cylinder.

[0009] Optionally, the vibrating plates are inclined, and the lower ends of the vibrating plates in the same group are inclined towards each other.

[0010] By adopting the above technical solution, the vibrating plates are set at an angle, and the lower ends of the vibrating plates in the same group are inclined towards each other. This design can effectively guide the material to slide down the inclined surface of the vibrating plates, and achieve uniform mixing of the material due to vibration during the sliding process. This design not only improves the uniformity of feeding, but also enhances the flowability of the material, avoiding the accumulation and blockage of material at the feed port, thereby improving the feeding efficiency and production efficiency of the extruder.

[0011] Optionally, a number of protruding rings are fixedly connected to the connecting rod.

[0012] By adopting the above technical solution, several protruding rings can also be fixedly connected to the connecting rod. The protruding rings can increase the contact area between the connecting rod and the material, thereby improving the disturbance effect of vibration on the material.

[0013] Optionally, the transition cylinder is provided with a guide plate for each of the vibration plates. The guide plate is located above the corresponding vibration plate and covers the upper surface of the corresponding elastic cover.

[0014] By adopting the above technical solution, the guide plate is located above the corresponding vibrating plate and covers the upper end face of the corresponding elastic cover, which is used to guide the material to be evenly distributed on the vibrating plate and prevent the material from accumulating or shifting during vibration.

[0015] Optionally, a buffer pad is provided on the side of the guide plate facing the corresponding vibration plate.

[0016] By adopting the above technical solution, a buffer pad can be set on the side of the guide plate facing the corresponding vibration plate. The buffer pad can absorb part of the vibration energy and protect the transition cylinder and vibration plate from damage.

[0017] Optionally, a support is provided outside the transition cylinder, and a buffer mechanism is provided on the support. The connecting rod is connected to the support through the buffer mechanism.

[0018] By adopting the above technical solution, a support is set outside the transition cylinder, and a buffer mechanism is set on the support. The connecting rod is connected to the support through the buffer mechanism. The setting of the buffer mechanism can further reduce the impact of vibration on the overall structure of the extruder and improve the stability and service life of the equipment.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. A vibrating plate is installed on the inner wall of the transition cylinder, and an elastic cover is connected between the vibrating plate and the inner wall of the transition cylinder. This allows the vibrating plate to maintain a certain amount of movement during vibration, avoiding direct contact with the inner wall of the transition cylinder and thus preventing wear. A connecting rod is installed on the vibrating plate and extends to the outside of the transition cylinder. A vibration motor is connected to the connecting rod. Driven by the vibration motor, the vibrating plate vibrates inside the transition cylinder, thereby promoting the uniform distribution and flow of materials.

[0021] 2. The vibrating plates in the same group are connected by connecting rods to enhance the vibration effect, allowing the material to flow more smoothly in the transition cylinder and reducing blockage;

[0022] 3. The inclined setting of the vibrating plate can effectively guide the material to slide down the inclined surface of the vibrating plate, which not only improves the uniformity of feeding, but also enhances the flowability of the material and avoids the accumulation and blockage of the material at the feeding port.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses an extruder feeding structure. For example... Figure 1 and Figure 2 The extruder feeding structure includes a guide ramp 1 disposed on the wall of the feed inlet 17. In this embodiment, multiple sets of guide ramps 1 are provided, with two guide ramps 1 in the same set, arranged opposite each other. The upper ends of the two guide ramps 1 are inclined in opposite directions, which guides the material. This design helps the material enter the extruder more smoothly and reduces the accumulation and blockage of material at the feed inlet 17.

[0029] like Figure 1 and Figure 3A transition cylinder 11 is provided on the feed inlet 17 of the extruder. A vibrating plate 12 is installed on the inner wall of the transition cylinder 11, and a connecting rod 14 is fixed on the vibrating plate 12. The connecting rod 14 extends to the outside of the transition cylinder 11 and is connected to the outer wall of the transition cylinder 11 through a buffer mechanism 2. A vibration motor 15 is connected to the connecting rod 14.

[0030] To ensure a stable connection between the vibratory motor 15 and the connecting rod 14, and to reduce the impact of vibration on the overall structure of the extruder, a bracket 16 is provided outside the transition cylinder 11 in this embodiment. The bracket 16 is fixed to the connecting rod 14 via a buffer mechanism 2. The buffer mechanism 2 can be a spring buffer mechanism 2, a rubber buffer mechanism 2, or a pneumatic buffer mechanism 2. This ensures effective driving of the vibratory motor 15 while effectively isolating vibration from interfering with other parts of the extruder, thus improving the stability and durability of the overall structure.

[0031] The vibrating plate 12 is flexibly connected to the inner wall of the transition cylinder 11 via an elastic cover 13, ensuring that the vibrating plate 12 can maintain a certain degree of freedom during vibration, while reducing the direct impact of vibration on the structure of the transition cylinder 11. Driven by the vibration motor 15, the reciprocating vibration of the vibrating plate 12 is realized, thereby effectively promoting the uniform distribution and flow of materials in the transition cylinder 11.

[0032] In this embodiment, the vibrating plate 12 is arranged in one or more sets within the transition cylinder 11, with two vibrating plates 12 in each set, positioned opposite each other within the transition cylinder 11 to create a bidirectional vibration effect on the material, further improving the material dispersion effect. The lower ends of the vibrating plates 12 in the same set are inclined towards each other. This design makes it easier for the material to slide down the vibrating plate 12 under vibration, effectively avoiding material retention and accumulation within the transition cylinder 11, and further enhancing the flowability of the material during vibration.

[0033] Furthermore, the vibrating plates 12 in the same group are connected by connecting rods 3 to ensure that the vibration of each group of vibrating plates 12 is coordinated and consistent during vibration, thereby enhancing the vibration effect. Several protruding rings 31 are fixedly connected to the connecting rods 3. The presence of the protruding rings 31 increases the contact area between the connecting rods 3 and the material. When the material flows through the connecting rods 3, the protruding rings 31 can play a further role in stirring and dispersing, thereby improving the uniformity of the material.

[0034] To protect the elastic cover 13 from direct impact from materials, in this embodiment, guide plates 32 are provided inside the transition cylinder 11 at positions corresponding to each vibrating plate 12. The guide plates 32 are located above the corresponding vibrating plate 12 and cover the upper surface of the corresponding elastic cover 13, effectively preventing materials from directly impacting the elastic cover 13, extending the service life of the elastic cover 13, and also reducing the accumulation of materials on the upper surface of the elastic cover 13.

[0035] A buffer pad 33 is provided on the side of the guide plate 32 facing the corresponding vibrating plate 12. The buffer pad 33 is made of a soft and wear-resistant material. The buffer pad 33 is used to reduce the impact of the vibrating plate 12 on the guide plate 32, thereby reducing the mutual wear between the guide plate 32 and the vibrating plate 12.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
