Abstract
Description
Technical Field
[0001] This utility model relates to the field of extruder technology, and in particular to a profile customization extruder with quick mold change capability. Background Technology
[0002] Extruders are core equipment for processing polymer materials such as plastics and rubber. They mainly consist of a barrel, screw, heating and cooling system, and forming die. Their working principle is as follows: after the material enters the barrel from the hopper, it is conveyed forward by the rotating screw. At the same time, it is melted and plasticized by the heating system, then pressurized and homogenized by the screw compression section, and finally extruded through a die of a specific shape. After cooling and shaping, products such as pipes, films, and profiles are obtained. Common types include single-screw and twin-screw extruders, which are widely used in packaging, building materials, automobiles, electronics and other industries. They are key equipment for realizing continuous material forming.
[0003] As a key forming component of an extruder, the die head's structure directly determines the cross-sectional shape of the product and is a core component for processing diverse products such as pipes and profiles.
[0004] Currently, the industry commonly uses bolt connections to fix the die head to the end of the extruder barrel. While this method ensures connection stability, it has significant limitations in actual production. When switching to produce products of different specifications or shapes, multiple fastening bolts must be disassembled one by one using tools, making the operation cumbersome. Especially in flexible production scenarios with small batches and multiple product categories, a single die change often takes a long time, and repeated disassembly of bolts can easily lead to stripping and positioning deviations, requiring additional calibration afterward, further increasing working hours and extending equipment downtime. This severely restricts the continuous production efficiency of the extruder, creating a prominent contradiction with the current manufacturing industry's demand for rapid changeover and efficient production.
[0005] Therefore, it is necessary to invent a profile customization extruder with quick mold change capability to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a profile customization extruder with rapid die change capability, in order to solve the problem mentioned in the background art, where the industry currently uses bolt connections to fix the die head to the end of the extruder barrel. Although this method can ensure connection stability, it has significant limitations in actual production. When it is necessary to switch to produce products of different specifications or shapes, multiple fastening bolts must be disassembled one by one with the help of tools. The operation process is cumbersome. Especially in flexible production scenarios with small batches and multiple categories, a single die change often takes a long time. Moreover, repeated disassembly of bolts can easily lead to stripping and positioning deviations, requiring additional calibration afterward, which further increases the working time and extends the equipment downtime. This seriously restricts the continuous production efficiency of the extruder, creating a prominent contradiction with the current manufacturing industry's demand for rapid die change and efficient production.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a profile customization extruder with quick die change capability, comprising an extruder body, a bottom plate fixedly connected to the bottom end of the extruder body, a feeding pipe provided on one side of the extruder body, a feed hopper fixedly connected to the top end of the feeding pipe, a customization die head provided on one side of the feeding pipe, side plates fixedly connected to both sides of the customization die head, and positioning holes provided on both sides of the top end of the side plates; A frame is provided at the top of the material conveying pipe near the customized mold head, and a support plate is fixedly connected to one side of the frame. The support plate is fixedly connected to the top of the material conveying pipe. A cylinder is fixedly connected to the top of the frame, and a mounting plate is fixedly connected to the output end of the cylinder. Positioning rods are fixedly connected to both sides of the bottom end of the mounting plate, and the positioning rods are set to correspond to the positioning holes.
[0008] As a preferred embodiment, L-shaped plates are fixedly connected to both sides of the bottom end of the support plate, and a guide rod is fixedly connected to one side of the L-shaped plate.
[0009] As a preferred embodiment, a fixing ring is fixedly connected to the outer side of the guide rod, and a spring is fixedly connected to one side of the fixing ring, with the spring sleeved on the outer side of the guide rod.
[0010] As a preferred embodiment, a retaining ring is slidably provided on the outer side of the guide rod, and the retaining ring is fixedly connected to one side of the spring.
[0011] As a preferred embodiment, the customized mold head has symmetrical through holes on both sides, and the through holes are correspondingly set with the guide rod.
[0012] As a preferred embodiment, the material conveying pipe is fixedly connected to an outlet on the side near the customized die head, and limit blocks are fixedly connected to both sides of the outlet. The inner side of the customized die head near the material conveying pipe is provided with a groove corresponding to the outlet and the limit blocks.
[0013] The technical effects and advantages of this utility model are as follows: This invention features a frame, cylinder, mounting plate, and positioning rod. The positioning rod can be inserted into the inside of the positioning hole. After the customized die head is fitted onto the outside of the discharge port, the positioning rod effectively limits the position of the customized die head, ensuring that the customized die head is stably positioned on the side of the conveying pipe without the need for bolts for fixing. When the customized die head needs to be replaced, simply slide the positioning rod out from the inside of the positioning hole to remove the limiting effect on the customized die head. This effectively limits the position of the customized die head while quickly disassembling it, facilitating rapid replacement. This invention features a discharge port and a limiting block on one side of the feeding pipe, and a groove corresponding to the discharge port and the limiting block on one side of the customized die head relative to the feeding pipe. This allows the customized die head to be fitted onto the outside of the discharge port and the limiting block, effectively limiting the position of the customized die head. This ensures that the customized die head can stably and at a fixed angle communicate with the discharge port, keeping the side plate in a horizontal position, which facilitates subsequent snap-fit and limiting of the customized die head.

Detailed Implementation
[0016] 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.
[0017] Please see the appendix Figure 1 - Appendix Figure 4 A profile customization extruder with quick die change capability includes an extruder body 1, a bottom plate 11 fixedly connected to the bottom end of the extruder body 1, a feed pipe 12 provided on one side of the extruder body 1, a feed hopper 13 fixedly connected to the top end of the feed pipe 12, a customization die head 2 provided on one side of the feed pipe 12, and side plates 21 fixedly connected to both sides of the customization die head 2, with positioning holes 22 opened on both sides of the top end of the side plates 21. A frame 3 is provided at the top of the feed pipe 12 near the customized mold head 2. A support plate 31 is fixedly connected to one side of the frame 3. The support plate 31 is fixedly connected to the top of the feed pipe 12. A cylinder 32 is fixedly connected to the top of the frame 3. A mounting plate 33 is fixedly connected to the output end of the cylinder 32. Positioning rods 34 are fixedly connected to both sides of the bottom end of the mounting plate 33. The positioning rods 34 are set to correspond to the positioning holes 22.
[0018] Specifically, after the customized mold head 2 is fitted onto the side of the feed pipe 12, the cylinder 32 can be used to drive the mounting plate 33 to move downwards, so that the positioning rod 34 is inserted into the inside of the positioning hole 22, so that the customized mold head 2 is stably set on the side of the feed pipe 12 without the need for bolts for limiting and fixing. When it is necessary to replace the customized mold head 2, simply slide the positioning rod 34 out from the inside of the positioning hole 22 to cancel the limiting of the customized mold head 2. This can effectively limit the customized mold head 2 while quickly disassembling it, making it easy to replace quickly.
[0019] Please see the appendix Figure 4 L-shaped plates 35 are fixedly connected to both sides of the bottom end of the support plate 31. A guide rod 36 is fixedly connected to one side of the L-shaped plate 35. A fixing ring 37 is fixedly connected to the outside of the guide rod 36. A spring 38 is fixedly connected to one side of the fixing ring 37. The spring 38 is sleeved on the outside of the guide rod 36. A retaining ring 39 is slidably provided on the outside of the guide rod 36. The retaining ring 39 is fixedly connected to one side of the spring 38.
[0020] Specifically, L-shaped plates 35 are fixedly connected to both sides of the bottom end of the support plate 31. A guide rod 36 is fixedly connected to one side of the L-shaped plate 35. A fixing ring 37 is fixedly connected to the outer side of the guide rod 36. A spring 38 is fixedly connected to one side of the fixing ring 37. The spring 38 is sleeved on the outer side of the guide rod 36. A retaining ring 39 is slidably arranged on the outer side of the guide rod 36. The retaining ring 39 is fixedly connected to one side of the spring 38. The fixing ring 37 is fixed on the outer side of the guide rod 36. When the retaining ring 39 is compressed, the retaining ring 39 moves along the outer side of the guide rod 36 toward the L-shaped plate 35, causing the spring 38 to be compressed and contracted.
[0021] Please see the appendix Figure 1 and Figure 4 The customized mold head 2 has symmetrical through holes 23 on both sides, and the through holes 23 are set in correspondence with the guide rod 36.
[0022] Specifically, through holes 23 are symmetrically provided on both sides of the customized mold head 2, and the through holes 23 are correspondingly set with the guide rod 36. In actual use, after the customized mold head 2 is sleeved on the outside of the discharge port 14, the through holes 23 are aligned with the guide rod 36 and the guide rod 36 is slidably set inside the through holes 23, which effectively limits the position of the side plate 21. While the side plate 21 slides on the outside of the guide rod 36, the retaining ring 39 moves towards the L-shaped plate 35, so that the spring 38 is compressed.
[0023] Please see the appendix Figure 1 , Figure 2 and Figure 3 The material conveying pipe 12 is fixedly connected to the discharge port 14 on the side near the customized mold head 2. Limiting blocks 15 are fixedly connected to both sides of the discharge port 14. The inner side of the customized mold head 2 near the material conveying pipe 12 is provided with a groove corresponding to the discharge port 14 and the limiting block 15.
[0024] Specifically, by providing an outlet 14 and a limiting block 15 on one side of the conveying pipe 12, and providing a groove on the side of the customized die head 2 corresponding to the outlet 14 and the limiting block 15 relative to the conveying pipe 12, the customized die head 2 can be sleeved on the outside of the outlet 14 and the limiting block 15, thereby effectively limiting the position of the customized die head 2, so that the customized die head 2 can stably and at a fixed angle communicate with the outlet 14, and the side plate 21 can maintain a horizontal position, which is convenient for subsequent snap-fit limiting of the customized die head 2.
[0025] The working principle of this utility model is as follows: When it is necessary to install the customized mold head 2, an outlet 14 and a limiting block 15 are provided on one side of the feeding pipe 12. The customized mold head 2 is provided with a groove corresponding to the outlet 14 and the limiting block 15 on the side opposite to the feeding pipe 12. This allows the customized mold head 2 to be sleeved on the outside of the outlet 14 and the limiting block 15, thereby effectively limiting the position of the customized mold head 2. This allows the customized mold head 2 to be stably and at a fixed angle connected to the outlet 14, so that the side plate 21 can be kept in a horizontal position, which is convenient for subsequent snap-fit and limiting of the customized mold head 2. Meanwhile, the side plate 21 is slidably disposed on the outside of the guide rod 36 through the through hole 23, so that the retaining ring 39 is pushed to move along the guide rod 36 towards the L-shaped plate 35. When the retaining ring 39 is squeezed, the retaining ring 39 moves along the outside of the guide rod 36 towards the L-shaped plate 35, so that the spring 38 is squeezed and contracted. The cylinder 32 drives the mounting plate 33 to move downward, so that the positioning rod 34 is inserted into the inside of the positioning hole 22 to limit the position of the customized mold head 2, and no bolts are needed for limiting and fixing. When the custom mold head 2 needs to be replaced, simply slide the positioning rod 34 out from the inside of the positioning hole 22 to cancel the limit of the custom mold head 2. The spring 38 pushes the retaining ring 39 to drive the side plate 21 to slide out from the outside of the guide rod 36, so that the custom mold head 2 can quickly slide down from the side of the feed tube 12, which is convenient for subsequent replacement.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
