Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to an adjustable diameter extrusion die device. Background Technology

[0002] An adjustable-diameter extrusion die is a component of an extrusion molding process. It is installed at the end of the extruder and works in conjunction with the barrel and screw. During extrusion, the material (such as plastic or rubber) is heated, mixed, and molten, then pushed into the extrusion die by the screw.

[0003] An adjustable-diameter extrusion die typically consists of an exit plate, an alignment mechanism, and an outlet. Therefore, when in use, the exit plate is the core component of the adjustable-diameter extrusion die, and its main function is to provide a shaped exit channel for the molten material. The main function of the alignment mechanism is to ensure the accurate installation and positioning of the exit plate on the extruder. The outlet is the final forming part of the adjustable-diameter extrusion die, and it is the key area where the molten material leaves the die and forms the final product shape.

[0004] However, in some existing devices, the diameter of the outlet plate is often fixed after manufacturing. This non-adjustable diameter design makes the device lack sufficient flexibility when facing the production needs of products with different specifications. It not only consumes a lot of time and labor costs, but also leads to material waste and equipment idleness in the production process. Therefore, an adjustable diameter extrusion die device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an adjustable diameter extrusion die device, which aims to improve the problem that some existing devices cannot adjust the diameter of the outlet plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable diameter extrusion die device includes an outlet plate, with adjustment mechanisms provided on both outer sides of the outlet plate, a groove provided on the outer side of the adjustment mechanism, and a cleaning mechanism provided inside the groove.

[0008] The adjusting mechanism includes multiple sliders, which are slidably connected to the outer sides of the outlet plate. Multiple sliding grooves are formed on the outer sides of the outlet plate. The sliders are fixedly connected to the inside of the sliding grooves. A connecting rod is fixedly connected to the outer side of the sliders. Two limiting rods are fixedly connected to the adjacent side of the connecting rods. The sliding grooves are formed inside the limiting rods. A positioning component is slidably connected to the front side of the outlet plate. Anti-detachment columns are slidably connected to the inside of the sliders. A placement plate is fixedly connected to the top of the anti-detachment columns. Rotating bolts are threaded into the inside of the connecting rods. Bolt holes are formed inside the sliding grooves.

[0009] As a further description of the above technical solution:

[0010] The positioning assembly includes multiple positioning rods, which are externally slidably connected to the front side of the outlet plate. Multiple positioning grooves are formed on the front side of the outlet plate, and the external sides of the multiple positioning rods are externally slidably connected to the interior of the positioning grooves.

[0011] As a further description of the above technical solution:

[0012] The cleaning mechanism includes a sliding block, the outside of which is slidably connected to the inside of the slide groove, and a rotating plate is rotatably connected to the front side of the outside of the sliding block;

[0013] As a further description of the above technical solution:

[0014] A movable column is rotatably connected to the outer front side of the rotating plate, and a support plate is fixedly connected to the outside of the movable column.

[0015] As a further description of the above technical solution:

[0016] A rotating column is rotatably connected to the top of the support plate, and a scraper is fixedly connected to the outside of the rotating column.

[0017] As a further description of the above technical solution:

[0018] The scraper is externally slidably connected to the front side of the outlet plate, and the sliding block is externally located on the front side of the outlet plate.

[0019] As a further description of the above technical solution:

[0020] The placement plate drives the anti-detachment column to slide externally to the top of the rotating bolt and the connecting rod;

[0021] As a further description of the above technical solution:

[0022] The rotating column drives the scraper to rotate, and then the movable column and the support plate rotate, which allows the scraper to be removed from the outer front groove of the outlet plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when it is necessary to adjust the diameter of the outlet plate, multiple sliders slide smoothly in the sliding groove, driving the connecting rod and the limiting rod to move smoothly, thereby accurately changing the opening width of the outlet plate. The adjustment process is easy and convenient, effectively meeting the extrusion requirements of materials of different sizes, improving production efficiency and flexibility, and enabling quick adjustment of the opening size.

[0025] 2. In this utility model, the sliding block slides flexibly to the designated position in the groove, and the rotating plate rotates smoothly to drive the movable column to slide. At the same time, the movable column itself can rotate flexibly, thereby making the support plate rotate stably. Finally, the scraper slides efficiently in the groove on the outer front side of the outlet plate for cleaning, which greatly improves the flexibility of cleaning operation and the convenience of equipment operation and maintenance, and effectively shortens the cleaning time.

[0032] 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.

[0033] Reference Figure 2 and Figure 3 An embodiment of this utility model is provided: an adjustable diameter extrusion die device, including an outlet plate 1, an adjustment mechanism 2 is provided on both sides of the outer side of the outlet plate 1, and a slide groove 3 is provided on the outer side of the adjustment mechanism 2. The design can provide good sliding space. At the same time, the slide groove 3 is designed near the bottom of the front side of the outlet plate 1, and a cleaning mechanism 4 is provided inside the slide groove 3.

[0034] The adjusting mechanism 2 includes multiple sliders 21, designed to provide good sliding capability. The sliders 21 are externally slidably connected to both sides of the outlet plate 1. Multiple sliding grooves 22 are formed on both sides of the outlet plate 1, designed to provide ample sliding space, allowing the sliders 21 to slide smoothly within the sliding grooves 22. The sliders 21 are externally fixedly connected to the inside of the sliding grooves 22, and connecting rods 23 are externally fixedly connected to the sliders 21, designed to provide good support. The sliding of the sliders 21 within the sliding grooves 22 allows for... The connecting rod 23 can slide together with it. Two limiting rods 24 are fixedly connected to the outer adjacent side of the connecting rod 23. Its design can provide good limiting ability. At the same time, the surface of the limiting rod 24 can fit against the outer front side of the outlet plate 1. The outer side of the slide groove 3 is opened inside the limiting rod 24. A positioning assembly is slidably connected to the outer front side of the outlet plate 1. The positioning assembly includes multiple positioning rods 27. Its design can provide good positioning ability, so that the outlet plate 1 can be quickly aligned. The outer sides of the multiple positioning rods 27 are slidably connected to the outer front side of the outlet plate 1.

[0035] Multiple positioning grooves 28 are provided on the outer front side of the outlet plate 1. This design provides ample sliding space, allowing the positioning rods 27 to slide within the positioning grooves 28 for quick mechanical alignment and fixation of the outlet plate 1. The external surfaces of the multiple positioning rods 27 are slidably connected to the interior of the positioning grooves 28. Multiple sliders 21 are internally slidably connected to anti-detachment posts 210, providing good support and locking capabilities. Placement plates 26 are fixedly connected to the tops of the multiple anti-detachment posts 210, enabling the multiple anti-detachment posts 210 to be removed and placed together. The internal surfaces of the multiple connecting rods 23... The threaded connection includes a rotating bolt 25, which is designed to provide good limiting capability. Multiple sliding grooves 22 have bolt holes 29 inside, which are designed to provide good positioning capability. This allows the rotating bolt 25 to be threaded into the connecting rod 23 and the slider 21 in one operation, and then threaded into the bolt hole 29. This allows the slider 21 to be positioned at different heights, and the opening and closing of the two limiting rods 24 can be fixed. The placement plate 26 drives the anti-detachment column 210 to slide externally on the top of the rotating bolt 25 and the connecting rod 23, which prevents the rotating bolt 25 from loosening during processing.

[0036] Reference Figure 1 and Figure 4 The cleaning mechanism 4 includes a sliding block 41, designed to provide good sliding ability. The sliding block 41 is externally slidably connected to the inside of the slide groove 3, allowing the sliding block 41 to slide smoothly within the slide groove 3. A rotating plate 42 is rotatably connected to the front of the sliding block 41, designed to provide good rotation ability, allowing it to rotate smoothly outside the sliding block 41. A movable column 43 is rotatably connected to the front of the rotating plate 42, designed to provide good rotation ability. A support plate 44 is fixedly connected to the outside of the movable column 43, allowing the support plate 44 to rotate smoothly by rotating the movable column 43. The top of the support plate 44 is rotatably connected to a rotating column 45, which is designed to provide good rotational capability. A scraper 46 is fixedly connected to the outside of the rotating column 45. By rotating the rotating column 45, the scraper 46 can be rotated for recycling. At the same time, the scraper 46 can slide and clean through the internal opening of the outlet plate 1. The outside of the scraper 46 is slidably connected to the front outside of the outlet plate 1. The outside of the sliding block 41 is on the front outside of the outlet plate 1. By rotating the rotating column 45, the scraper 46 is rotated. Then, the movable column 43 and the support plate 44 rotate, which can remove the scraper 46 from the groove on the front outside of the outlet plate 1.

[0037] Working principle: At the start of operation, the positioning rod 27 slides within the positioning groove 28, achieving rapid alignment and fixation of the outlet plate 1. When the diameter of the outlet plate 1 needs to be adjusted, multiple sliders 21 slide within the sliding grooves 22 on both sides of the outlet plate 1, causing the connecting rod 23 to slide together. The connecting rod 23 causes the two limiting rods 24 to move closer or further apart, changing the opening width of the outlet plate 1. After adjustment, the rotating bolt 25 is threaded onto the connecting rod 23 and the slider 21, and inserted into the bolt hole 29 in the sliding groove 22 to position the slider 21 at different heights. At the same time, the anti-detachment column 210 and the placement plate 26 prevent the slider 21 from detaching and prevent the rotating bolt 25 from loosening during processing.

[0038] When the diameter of the outlet plate 1 is adjusted after processing, the sliding block 41 slides to the designated position in the groove 3. The rotating plate 42 rotates, which in turn drives the movable column 43 to slide. At the same time, the movable column 43 can rotate itself. The rotation of the movable column 43 causes the support plate 44 to rotate, which in turn drives the rotating column 45 to rotate. The rotation of the rotating column 45 causes the scraper 46 to slide in the groove on the outer front side of the outlet plate 1 to clean the groove. After cleaning, the rotating column 45 drives the scraper 46 to rotate in the opposite direction. At the same time, the movable column 43 and the support plate 44 rotate in coordination, placing the scraper 46 on the outer front side of the outlet plate 1 for easy cleaning at any time.

[0039] 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.
