Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a pressure equalizing ring structure for an HDPE plastic bottle extruder. Background Technology

[0002] HDPE plastic bottles are widely used in the food and daily chemical packaging industries due to their corrosion resistance and lightweight properties. As the core production equipment, the extruder's pressure equalization ring structure directly determines the stability of the plastic melt extrusion, which in turn affects the uniformity of the bottle wall thickness and the molding quality.

[0003] However, common pressure equalization rings in extruders lack effective aggregating components, making it easy for plastic materials to disperse during extrusion and difficult to flexibly block and aggregate. This results in insufficient material flow from the extrusion orifice, leading to localized material shortages or overflows, which affects product consistency. At the same time, the compression spring inside the pressure equalization ring is difficult to adjust, and after long-term use, it becomes fatigued and unable to maintain the normal pressure of the aggregating components, causing the performance of the pressure equalization ring to deteriorate and reducing the operational stability of the extruder. Therefore, there is an urgent need for a pressure equalization ring structure for HDPE plastic bottle extruders to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pressure equalizing ring structure for an HDPE plastic bottle extruder, in order to solve the problem mentioned in the background art that common pressure equalizing rings for extruders lack effective aggregation components, making it easy for plastic materials to disperse during extrusion and difficult to flexibly block aggregation, resulting in insufficient material flow from the extrusion orifice.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure equalizing ring structure for an HDPE plastic bottle extruder, comprising an extrusion ring, one end of which has multiple extrusion holes, and further comprising: An agglomeration assembly, disposed on the inner wall of the extrusion ring, is used to elastically agglomerate the plastic before extrusion. An adjustment component, disposed on the inner wall of the extrusion ring, is used to adjust the elastic force of the agglomeration component.

[0006] Preferably, the aggregation component includes multiple aggregation heads, which are slidably connected to the inner wall of the extrusion orifice. The other end of the extrusion ring is provided with multiple mounting grooves, and the inner wall of the mounting grooves is provided with compression springs.

[0007] Preferably, when there is insufficient extruded material, the extrusion pressure of the material on the converging head decreases. As the extrusion pressure of the converging head decreases, the compression spring extends and pushes the converging head to move, thereby using the converging head to block the extrusion orifice and thus re-converge the injection molding material.

[0008] Preferably, the adjusting assembly includes a plurality of adjusting threaded tubes, the adjusting threaded tubes being disposed on the inner wall of the mounting groove, the inner wall of the mounting groove having a fixing groove, the inner wall of the fixing groove having a threaded fixing head, the inner wall of the threaded fixing head being threadedly connected to the surface of the adjusting threaded tube, and one end of the adjusting threaded tube abutting against one end of the compression spring.

[0009] Preferably, the inner wall of the mounting groove is provided with a sliding hole, a sliding column is slidably connected to the inner wall of the sliding hole, a force-bearing ring is fixedly connected to the surface of the sliding column, and one end of the sliding column is fixedly connected to one end of the converging head.

[0010] Preferably, the inner wall of the fixing groove is provided with multiple threaded grooves, and the threaded fixing head is detachably connected to the threaded grooves by bolts.

[0011] Preferably, the surface of the adjusting threaded tube is threaded with a fixing nut, one end of which abuts against one end of the threaded fixing head.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The agglomeration component allows for flexible blocking of the extruded plastic material, causing it to converge. As the converged material increases, it pushes the agglomeration head to move and open the obstruction to the extrusion orifice. This material convergence improves the flow rate and uniformity of the discharge from the extrusion orifice. Simultaneously, the adjustment component allows for adjustment of the compression spring's pressure, facilitating compensation for spring fatigue after long-term use and ensuring the agglomeration component maintains good performance.

[0015] 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.

[0016] Please see Figure 1 - Figure 3 The present invention provides a pressure equalizing ring structure for an HDPE plastic bottle extruder, comprising an extrusion ring 1, one end of which has a plurality of extrusion holes 2, and further comprising: An agglomeration component is disposed on the inner wall of the extrusion ring 1 and is used to elastically agglomerate the plastic before extrusion. An adjustment component is disposed on the inner wall of the extrusion ring 1 and is used to adjust the elastic force of the agglomeration component; By setting up the aggregation component, the material is brought together, thereby increasing the fullness of the flow rate during discharge inside the extrusion orifice 2 and improving the uniformity of discharge. At the same time, the setting up the adjustment component makes it easy to adjust the elastic force of the aggregation component according to the raw material extrusion pressure, and to compensate for the elastic fatigue of the compression spring 306 after long-term use, so that the aggregation component can maintain good performance.

[0017] Furthermore, the aggregation assembly includes multiple aggregation heads 301, which are slidably connected to the inner wall of the extrusion orifice 2. Multiple mounting grooves 302 are provided at the other end of the extrusion ring 1. Compression springs 306 are provided on the inner wall of each mounting groove 302. Sliding holes 303 are provided on the inner wall of each mounting groove 302. Sliding pillars 304 are slidably connected to the inner wall of each sliding hole 303. A force-bearing ring 305 is fixedly connected to the surface of each sliding pillar 304. One end of each sliding pillar 304 is fixedly connected to one end of the aggregation head 301. Through the aggregation assembly, the aggregation head 301 is pushed by the elastic action of the compression springs 306, causing the aggregation head 301 to abut against the inner wall of the extrusion orifice 2. This facilitates flexible blocking of the extruded plastic material, allowing the material to aggregate. When enough extruded plastic material has aggregated, the continuous extrusion of the extruder causes the material to aggregate. Under the continuous mutual compression, the density between the aggregated plastic materials decreases, and the amount of aggregated material continues to increase, thus pushing the converging head 301 to move and open the obstruction to the extrusion orifice 2. This allows the aggregated material to flow outward through the interior of the converging head 301. Through the mutual aggregation of materials, the fullness of the flow rate during discharge from the extrusion orifice 2 is improved, and the uniformity of discharge is enhanced. When the extruded material is insufficient, the extrusion pressure on the converging head 301 decreases. As the extrusion pressure of the converging head 301 decreases, the compression spring 306 extends and pushes the converging head 301 to move, thereby using the converging head 301 to block the extrusion orifice 2 and thus re-aggregate the injection molding material. The sliding column 304 and the force ring 305 work together to facilitate the precise transfer of elastic potential energy from the compression spring 306 to the converging head 301.

[0018] Furthermore, the adjustment assembly includes multiple adjusting threaded tubes 401, which are disposed on the inner wall of the mounting groove 302. A fixing groove 402 is formed on the inner wall of the mounting groove 302, and a threaded fixing head 403 is disposed on the inner wall of the fixing groove 402. The inner wall of the threaded fixing head 403 is threadedly connected to the surface of the adjusting threaded tube 401. One end of the adjusting threaded tube 401 abuts against one end of the compression spring 306. A fixing nut 404 is threadedly connected to the surface of the adjusting threaded tube 401, and one end of the fixing nut 404 abuts against one end of the threaded fixing head 403. Through the adjustment assembly, the adjusting threaded tube 401... The surface of the threaded tube 401 is threadedly connected to the inner wall of the threaded fixing head 403, so that when the adjusting threaded tube 401 rotates, it moves to compress the compression spring 306, thereby changing the elastic force of the compression spring 306. This makes it easy to adjust the elastic force of the compression spring 306 according to the extrusion pressure of the raw material, and also makes it easy to compensate for the elastic fatigue of the compression spring 306 after long-term use, so that the aggregation component maintains good performance. The fixing nut 404 makes it easy to constrain the adjusting threaded tube 401 after adjustment, thereby improving the stability of the adjusting threaded tube 401 in use.

[0019] Furthermore, the inner wall of the fixing groove 402 is provided with multiple threaded grooves 405. The threaded fixing head 403 is detachably connected to the threaded grooves 405 by bolts. The detachable connection between the threaded fixing head 403 and the threaded grooves 405 facilitates the disassembly of the threaded fixing head 403 and the adjusting threaded tube 401 to replace or maintain the compression spring 306, thereby improving the convenience of replacement or maintenance.

[0020] Working principle: During use, the aggregation component, under the elastic action of the compression spring 306, pushes the aggregation head 301, causing it to abut against the inner wall of the extrusion orifice 2. This facilitates flexible obstruction of the extruded plastic material, allowing it to aggregate. When enough extruded plastic material has accumulated, the continuous extrusion of the extruder causes mutual compression between the materials, reducing the density between them. The increasing amount of aggregated material pushes the aggregation head 301 to move and open the obstruction of the extrusion orifice 2, allowing the aggregated material to flow outward through the interior of the aggregation head 301. This mutual aggregation of materials improves the flow rate and uniformity of the discharge from the extrusion orifice 2.

[0021] Meanwhile, the adjustable component allows the surface of the adjustable threaded tube 401 to be threadedly connected to the inner wall of the threaded fixing head 403. This causes the adjustable threaded tube 401 to rotate and move, squeezing the compression spring 306, thereby changing the elastic force of the compression spring 306. This facilitates the adjustment of the elastic force of the compression spring 306 according to the material extrusion pressure, and also facilitates compensation for elastic fatigue of the compression spring 306 after long-term use, thus ensuring that the aggregation component maintains good performance.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
