A twin-screw self-cleaning screw assembly / disassembly platform

Abstract

This utility model discloses a self-cleaning screw assembly / disassembly platform for a twin-screw extruder, relating to the field of twin-screw extruder technology. It includes an assembly / disassembly table, a disassembly / disassembly plate fixedly mounted on the top of the table, a placement strip fixedly mounted on the side wall of the disassembly / disassembly plate, and a fixing component fixedly mounted at the end of the disassembly / disassembly plate. The placement strip includes a sliding groove fixedly mounted on the side wall of the disassembly / disassembly plate, and a left-side fixing block fixedly mounted on the inner wall of the sliding groove. In this utility model, when unloading a threaded unit, a manually rotated torsion ring drives the screw tube to rotate, thereby causing the threaded block to move synchronously towards the left-side fixing block along with the adjusting block. When the inner wall partition sidewall of the adjusting block near the left-side fixing block abuts against the sidewall of the threaded unit, the rotation of the torsion ring stops, at which point the first threaded unit is stably fixed. Subsequent threaded units are then placed sequentially in other grooves according to the removal order, ensuring that each threaded unit is stably fixed.

Description

Technical Field

[0001] This utility model relates to the field of twin-screw extruder technology, specifically to a twin-screw extruder barrel self-cleaning screw assembly / disassembly platform. Background Technology

[0002] In the maintenance and repair of twin-screw extruder equipment, the disassembly and assembly of the screw is a critical and frequent operation. Currently, the common method used in the disassembly and assembly of the screw in twin-screw extruders is to place the screw directly on a flat surface to carry out the work.

[0003] When disassembling the screw, the threaded units usually need to be removed and arranged one by one in a specific order. However, in the current operating environment, there is a lack of a device specifically for fixing the threaded units. If the arrangement order of the threaded units is disordered during the disassembly process, due to the complex screw structure of the twin-screw extruder and the precise and tight assembly relationship between each threaded unit, an incorrect sequence may cause the screw to be unable to be properly installed back into the barrel. Even if it is installed with difficulty, improper assembly may affect the normal operation of the equipment, reduce production efficiency, or even cause equipment failure, resulting in greater economic losses.

[0004] The shape of the threaded unit makes it extremely prone to rolling. When disassembling and assembling on a normal flat surface, the threaded unit may roll randomly due to accidental collisions or slight touches by the operator. This not only increases the difficulty for the operator to manage the threaded unit, but may also lead to the loss or damage of the threaded unit, further affecting the disassembly and assembly progress and quality of the screw.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this utility model is to provide a twin-screw barrel self-cleaning screw disassembly and assembly platform to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a twin-screw barrel self-cleaning screw disassembly and assembly platform, including a disassembly and assembly table, a disassembly and assembly plate fixedly installed on the top of the disassembly and assembly table, a placement strip fixedly installed on the side wall of the disassembly and assembly plate, and a fixing component fixedly installed at the end of the disassembly and assembly plate;

[0008] The placement strip includes a slide groove fixedly installed on the side wall of the disassembly plate. A left-side fixing block is fixedly installed on the inner wall of the slide groove. A screw tube is rotatably installed on the bottom inner wall of the left-side fixing block. A torsion ring is fixedly installed on the side end of the screw tube. A threaded block is threadedly installed on the outer wall of the screw tube away from the torsion ring. The number of threaded blocks can be increased or decreased according to the number of thread units. An adjusting block is fixedly installed on the top of the threaded block. A partition is fixedly installed in the middle section of the inner wall of the adjusting block. A right-side fixing block is threadedly connected to the end of the screw tube away from the left-side fixing block.

[0009] A connecting rod is rotatably mounted at the bottom of the threaded block, and another connecting rod is rotatably mounted at both ends of the connecting rod. Another threaded block is rotatably mounted in the middle section of the other connecting rod.

[0010] Furthermore, another guide block is fixedly installed on the side of the lower pressing block away from the guide block, and a clamping block two is slidably installed on the side wall of the other guide block. The internal structure of the clamping block two is the same as that of the clamping block one. A gasket is fixedly installed on the top of the lower pressing block. An arc-shaped groove is opened on the top of the gasket. A rubber pad is provided on the inner wall of the clamping plate. An integrally formed anti-slip texture is opened on the surface of the rubber pad.

[0011] Furthermore, the fixing component includes two limiting frames fixedly installed on the side of the disassembly plate. Each of the two limiting frames has a clamping block slidably installed on its inner wall. Each clamping block includes a guide groove. A pressing block is slidably installed on the side wall of the guide groove. A translation block is provided on the side wall of the guide groove. A guide block is slidably installed on the inner wall of the translation block. The guide block is fixedly connected to the side wall of the pressing block. A clamping plate is fixedly installed on the top of the clamping block.

[0012] Furthermore, a spring is fixedly connected to the bottom of the pressing block, and the bottom of the spring is fixedly connected to the bottom of the inner wall of the limiting frame.

[0013] Furthermore, the top of the disassembly plate has two disassembly grooves, the inner walls of which are consistent with the curvature of the inner wall of the clamping plate, the adjusting block is made of rubber, and the thickness of the adjusting block is 1cm.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When removing the threaded unit, manually rotate the torsion ring to rotate the threaded tube, which in turn causes the threaded block to move synchronously towards the left fixed block. When the inner wall of the partition plate of the adjusting block near the left fixed block abuts against the side wall of the threaded unit, stop rotating the torsion ring. At this time, the first threaded unit is stably fixed. Then, place the subsequent threaded units in other grooves in the order of removal to ensure that each threaded unit is stably fixed, which facilitates the accurate installation of the subsequent screw and ensures the normal operation of the equipment.

[0016] 2. By opening a disassembly and assembly groove on the top of the disassembly and assembly plate, and cooperating with the fixing components, the screw is stably fixed, which effectively prevents the screw from shaking or shifting during disassembly and assembly. Compared with the screw being placed directly on an ordinary flat surface, which is prone to shaking and shifting, this utility model can provide a stable working environment for screw disassembly and assembly, and improve the accuracy and safety of disassembly and assembly operations.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-5This utility model provides a technical solution: a self-cleaning screw assembly / disassembly platform for a twin-screw extruder, comprising an assembly / disassembly table 1, an assembly / disassembly plate 2 fixedly mounted on the top of the assembly / disassembly table 1, a placement strip 3 fixedly mounted on the side wall of the assembly / disassembly plate 2, and a fixing component 4 fixedly mounted at the end of the assembly / disassembly plate 2. The placement strip 3 includes a sliding groove 301 fixedly mounted on the side wall of the assembly / disassembly plate 2, a left-side fixing block 302 fixedly mounted on the inner wall of the sliding groove 301, a screw tube 308 rotatably mounted on the bottom inner wall of the left-side fixing block 302, and a torsion ring 303 fixedly mounted on the side end of the screw tube 308. A threaded block 306 is installed on the outer wall thread of the solenoid 308 away from the torsion ring 303. The number of threaded blocks 306 can be increased or decreased according to the number of thread units. In the actual assembly and disassembly process of twin-screw extruders, the number of thread units equipped with different specifications and models of screws varies. The traditional method often uses a fixed number and spacing of placement slots to place thread units. When the number of thread units changes, there will be insufficient or wasted placement space. However, this utility model, through the increaseable and decreaseable threaded blocks 306 and the corresponding adjusting blocks 304, can adjust the number of thread units according to the actual situation. The precise adjustment of the thread unit placement space ensures that each thread unit has a suitable placement position, improving the versatility and practicality of the equipment. The number of thread blocks 306 can be increased or decreased according to the number of thread units. An adjusting block 304 is fixedly installed on the top of the thread block 306, and a partition 305 is fixedly installed in the middle section of the inner wall of the adjusting block 304. When the thread unit is placed in the groove of the adjusting block 304, the partition 305 can provide a certain support and limit to the thread unit from the side. By rotating the torsion ring 303, the thread tube 308 is driven to rotate, thereby making the thread block 306 rotate. 6. The adjusting block 304 is moved, allowing the partition 305 to abut tightly against the side wall of the threaded unit, thus achieving stable fixation of the threaded unit. The end of the threaded tube 308 away from the left fixing block 302 is threadedly connected to the right fixing block 309. A connecting rod 307 is rotatably mounted on the bottom of the threaded block 306. Another connecting rod 307 is rotatably mounted on both ends of the connecting rod 307. Another threaded block 306 is rotatably mounted on the middle section of the other connecting rod 307. The number of threaded blocks 306 can be increased or decreased according to the number of threaded units. When the rotating torsion ring 303 drives the threaded tube 308 to rotate, one of the threaded units... When the threaded block 306 moves, the other threaded blocks 306 will move synchronously through the transmission action of the connecting rod 307, ensuring that all adjusting blocks 304 can simultaneously fix or loosen the threaded unit. The operator only needs to rotate the torsion ring 303 to fix and loosen the threaded unit without complicated tools or cumbersome steps. The design of the adjusting block 304 and the partition 305 makes the placement and use of the threaded unit very convenient. The operator can clearly see the position of each threaded unit and quickly and accurately complete the disassembly and assembly work.

[0025] Please see Figure 3 , Figure 4This utility model provides a technical solution: a twin-screw self-cleaning screw assembly / disassembly platform, including a fixing assembly 4 comprising two limiting frames 401 fixedly installed on the side of the disassembly / disassembly plate 2. Each limiting frame 401 has a clamping block 402 slidably installed on its inner wall. Clamping block 402 and clamping block 405 are slidably installed within the two limiting frames 401 respectively. Clamping block 402 includes a guide groove 4023, and a pressing block 403 is slidably installed on the side wall of the guide groove 4023. When the pressing block... When force is applied to 403, clamping blocks 402 and 405 move from both sides toward the middle, achieving bidirectional clamping of the fixed component. This operation method is simple and intuitive, requiring no complicated operating steps or professional tools, thus improving operating efficiency. A translation block 4022 is provided on the side wall of the guide groove 4023, and a guide block 4031 is slidably installed on the inner wall of the translation block 4022. The guide block 4031 is fixedly connected to the side wall of the lower pressure block 403. A clamping block is fixedly installed on the top of clamping block 402. The contact area between the plate 4021 and the fixed part is large, which can disperse the fixing force and avoid damage to the fixed part due to local stress concentration. Another guide block 4031 is fixedly installed on the side of the lower pressure block 403 away from the guide block 4031. The second clamping block 405 is slidably installed on the side wall of the other guide block 4031. Since the first clamping block 402 and the second clamping block 405 can slide within the limiting frame 401, and different clamping distances can be achieved by adjusting the lower pressure block 403, the fixing component 4 can adapt to fixed parts of different sizes. Whether the screw is thick or thin, stable fixing can be achieved by adjusting the position and pressure of the clamping blocks. The internal structure of the second clamping block 405 is the same as that of the first clamping block 402. A spring 404 is fixedly connected to the bottom of the lower pressure block 403. The bottom of the spring 404 is fixedly connected to the bottom of the inner wall of the limiting frame 401. When the lower pressure block 403 is released, the clamping block will automatically release under the action of the spring 404.

[0026] Please see Figure 4 This utility model provides a technical solution: a twin-screw self-cleaning screw assembly / disassembly platform, including a pressure block 403 with a pad 4032 fixedly installed on its top. The pad 4032 provides the operator with a clear and specific force application position. The top of the pad 4032 has an arc-shaped groove. When it is necessary to press down the pressure block 403 to drive the clamping block to move and fix the component, the operator can use the area where the arc-shaped groove is located to quickly and accurately place his finger or other tool on the pad 4032 to apply pressure, without having to spend time finding a suitable pressing position, thus improving operating efficiency.

[0027] Please see Figure 1 , Figure 3This utility model provides a technical solution: a twin-screw self-cleaning screw assembly / disassembly platform, including an assembly / disassembly plate 2 with two assembly / disassembly slots 201 on the top. The assembly / disassembly slots 201 and the clamping plate 4021 have the same curvature, which provides a clear positioning reference for the operator. The inner wall of the assembly / disassembly slots 201 is consistent with the inner wall of the clamping plate 4021. The operator can quickly and accurately place the fixed parts in the assembly / disassembly slots 201 and align them with the clamping plate 4021.

[0028] Working principle: Two screws to be cleaned are placed in the disassembly groove 201 on the top of the disassembly plate 2. The bottom surface of the screw end abuts against the gasket 4032 on the top of the pressure block 403 in the limiting frame 401 of the fixing assembly 4. Under the action of the screw's gravity, the pressure block 403 moves downward, and the spring 404 is compressed. At the same time, the two guide blocks 4031 on the side wall of the pressure block 403 move in the guide grooves 4023 of the clamping block 1 402 and the clamping block 2 405 respectively, causing the clamping block 1 402 and the clamping block 2 405 to move relative to each other, so that the clamping plate 4021 clamps the outer wall of the screw end, thereby fixing the screw. Then, the threaded unit is removed, and the first threaded unit removed is placed on the left side of the placement bar 3. Within the groove of the side fixing block 302, manually rotate the torsion ring 303 on the side end of the screw tube 308, which is rotatably mounted on the inner wall of the bottom of the left fixing block 302. The rotation of the screw tube 308 causes the threaded block 306, which is threaded on its outer wall, to move synchronously towards the left fixing block 302. When the side wall of the partition plate 305 on the inner wall of the adjusting block 304 near the left fixing block 302 abuts against the side wall of the threaded unit, stop rotating the torsion ring 303. At this time, the first threaded unit is fixed. Afterward, place the subsequent threaded units in other grooves in sequence according to the removal order. This can accommodate different numbers of threaded units and ensure stable fixation, avoiding disorder and rolling, improving the efficiency and accuracy of screw assembly and disassembly, and ensuring the normal operation of the equipment.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
