Description

Technical Field

[0001] This utility model relates to the field of extrusion cylinder cleaning technology, and in particular to an extrusion cylinder residual aluminum cleaning device. Background Technology

[0002] In the modern aluminum profile processing industry, extrusion molding is a key process for producing various aluminum products. As the core component of extrusion equipment, the extrusion cylinder often has a large amount of aluminum chips and solidified metal residues left on its inner wall after the reverse extrusion process. These residues not only affect the quality of the next extruded product, but also cause the inner wall of the extrusion cylinder to wear more quickly, shortening the service life of the equipment. Therefore, an efficient and reliable extrusion cylinder residual aluminum cleaning device has become an important piece of equipment to ensure the continuity of aluminum profile production and product quality. Its performance directly affects the production efficiency and operating costs of enterprises.

[0003] Currently, common extrusion cylinder residual aluminum cleaning devices mainly adopt fixed or easily disassembled mechanical structures. For example, some devices fix the support frame to the top of the extruder with bolts, and the cleaning components are installed on the support frame. During cleaning, a hydraulic or pneumatic system is used to drive the cleaning tool to scrape and clean the inner wall of the extrusion cylinder. Other devices adopt an integrated design, integrating the cleaning mechanism with the extruder. The cleaning components are rotated by a motor to remove residual aluminum. The support frame fixing method of these traditional devices mostly relies on bolts and nuts and other connecting parts, requiring the use of various tools such as wrenches and screwdrivers for installation and disassembly. The cylinder gasket is usually fixed by welding or tightening screws to ensure its stability during the cleaning process.

[0004] However, existing extrusion cylinder residual aluminum cleaning devices have significant drawbacks in practical applications, especially in the fixing of the support frame. Due to the use of traditional bolt and nut connections, operators not only need to frequently use multiple tools when installing and disassembling the support frame, making the operation process cumbersome and complicated, but also consuming a lot of time and manpower. When the equipment needs maintenance or the cleaning device needs to be repositioned, this fixing method cannot achieve quick disassembly, which seriously affects the maintenance efficiency of the equipment and the continuity of production, making it difficult to meet the needs of modern aluminum profile processing enterprises for efficient production and convenient maintenance. Therefore, an extrusion cylinder residual aluminum cleaning device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a residual aluminum cleaning device for extrusion cylinders, which aims to improve the problem that multiple tools are required to fix the support frame in the prior art, making disassembly inconvenient.

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

[0007] An extrusion cylinder residual aluminum cleaning device includes a support frame, a drive rod fixedly connected to the outer wall of the support frame, a connecting rod fixedly connected to the output end of the drive rod, a connecting component provided at the bottom of the support frame, and a fixing component provided inside the connecting rod;

[0008] The connecting component includes a locking block, the top of which is disposed at the bottom of the support frame. A connecting block is fixedly connected to the bottom of the support frame.

A push rod is fixedly connected to the top of the connecting disc. The outer wall of the push rod is slidably connected to the inside of the sliding groove. A reset component is provided inside the connecting block.

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

[0010] The reset assembly includes a spring, one end of which is fixedly connected to the inside of the connecting block, and the other end of which is fixedly connected to the outer wall of the connecting disk.

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

[0012] The fixing component includes a locking post, the outer wall of which is slidably connected to the inside of the connecting rod.

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

[0014] The connecting rod is rotatably connected to a rotating rod inside, and a knob is fixedly connected to one end of the rotating rod.

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

[0016] The other end of the rotating rod is fixedly connected to a turntable, and the outer wall of the turntable is rotatably connected inside the connecting block.

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

[0018] The turntable has a limiting groove inside, and the connecting rod has a moving groove inside.

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

[0020] One end of the locking pin is fixedly connected to a limiting disc, and the outer wall of the limiting disc is slidably connected inside the moving groove.

[0027] This utility model has the following beneficial effects:

[0028] 1. In this utility model, the locking block achieves its movement function by pushing the push rod.

[0037] 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.

[0038] Reference Figures 1-3 This utility model provides an embodiment of an extrusion cylinder residual aluminum cleaning device, including a support frame 1. A drive rod 2 is fixedly connected to the outer wall of the support frame 1. The drive rod 2 adopts a hydraulic rod structure and is used to output linear driving force. It can accurately control the movement stroke and speed of the connecting rod 4, realize the rapid positioning and stable pushing of the cylinder cleaning gasket in the extrusion cylinder, and can smoothly feed the cylinder cleaning gasket into the extrusion cylinder at a speed of 0.5-2m / min. The output end of the drive rod 2 is fixedly connected to the connecting rod 4. The connecting rod 4 is a hollow rectangular tubular structure, made of 45# high-quality carbon structural steel, with good strength and rigidity, and can withstand the scraping resistance and friction reaction force during the cleaning process, ensuring that the cylinder cleaning gasket remains stable during the cleaning operation. A connecting component is provided at the bottom of the support frame 1, and a fixing component is provided inside the connecting rod 4.

[0039] The connecting assembly includes a locking block 8, the top of which is positioned at the bottom of a support frame 1. A connecting block 5 is fixedly connected to the bottom of the support frame 1. A sliding groove 7 is provided inside the support frame 1. A transmission block 19 is fixedly connected to one end of the locking block 8, and the outer wall of the transmission block 19 is slidably connected to the inside of the connecting block 5. A connecting disc 9 is fixedly connected to the other end of the transmission block 19. A push rod 6 is fixedly connected to the top of the connecting disc 9. The push rod 6 is a plate, and its outer wall is slidably connected to the sliding groove 7 inside the support frame 1. By pushing the push rod 6, the operator can drive the connecting disc 9, the transmission block 19, and the locking block 8 to slide inside the connecting block 5, thereby extending and retracting the locking block 8. The outer wall of the push rod 6 is slidably connected to the inside of the sliding groove 7. A reset assembly is provided inside the connecting block 5. The reset assembly includes a spring 10, one end of which is fixedly connected to the inside of the connecting block 5, and the other end of which is fixedly connected to the outer wall of the connecting disc 9.

[0040] Specifically, when cleaning the extrusion cylinder is required, the operator first places the support frame 1 stably at the preset position on top of the extruder. At this time, the push rod 6 located on the side of the support frame 1 is pushed, causing it to slide along the inside of the slide groove 7, which drives the connected disc 9 to move synchronously. During this process, the spring 10 is compressed, accumulating elastic potential energy. At the same time, the displacement of the connected disc 9 drives the transmission block 19 to move through the transmission structure. The transmission block 19 then transmits power to the locking block 8, causing the locking block 8 to move inside the connecting block. As the locking block 8 moves, it gradually embeds into the slot on top of the extruder. At this time, the support frame 1 is initially connected to the top of the extruder. After the position is confirmed to be correct, the push rod 6 is released, and the compressed spring 10 quickly rebounds. The resulting elastic force drives the locking block 8 to further engage in the slot inside the extruder, forming a stable mechanical connection. This ensures that the support frame 1 remains stable during subsequent cleaning operations, effectively avoiding the impact of shaking on the cleaning effect and equipment safety.

[0041] Reference Figure 1 , Figure 4 and Figure 5 The fixing component includes a locking pin 3, which is a cylindrical pin-shaped structure. Its outer wall is clearance-fitted with a through hole inside the connecting rod 4, and is used to insert into a pre-set slot in the cylinder cleaning gasket to achieve a fixed connection between the cylinder cleaning gasket and the connecting rod 4. This ensures that the cylinder cleaning gasket will not loosen or fall off when cleaning residual aluminum from the extrusion cylinder. The outer wall of the locking pin 3 is slidably connected to the inside of the connecting rod 4. A rotating rod 14 is rotatably connected inside the connecting rod 4. A knob 11 is fixedly connected to one end of the rotating rod 14. The surface of the knob 11 is provided with anti-slip texture to facilitate the operator to apply force to rotate it. A turntable 15 is fixedly connected to the other end of the rotating rod 14. The outer wall of the turntable 15 is rotatably connected to the inside of the connecting block 5. A limit groove 16 is provided inside the turntable 15. A moving groove 18 is provided inside the connecting rod 4. One end of the locking post 3 is fixedly connected to a limiting disc 12. The limiting disc 12 is a circular plate structure, and its outer wall is in sliding fit with the inner wall of the moving groove 18. It is used to limit the movement direction of the locking post 3 and ensure that the locking post 3 can only slide along the axial direction of the moving groove 18. The outer wall of the limiting disc 12 is slidably connected to the inside of the moving groove 18. A transmission column 20 is fixedly connected to the bottom of the limiting disc 12. The outer wall of the transmission column 20 is slidably connected to the outer wall of the turntable 15. A sliding column 17 is fixedly connected inside the transmission column 20. The outer wall of the sliding column 17 is slidably connected to the inside of the limiting groove 16. A second spring 13 is sleeved on the outer wall of the transmission column 20. One end of the second spring 13 is fixedly connected to the inner wall of the moving groove 18, and the other end of the second spring 13 is fixedly connected to the outer wall of the limiting disc 12.

[0042] Specifically, after the support frame 1 is securely connected to the top of the extruder, the cylinder cleaning gasket installation begins. The operator places the cylinder cleaning gasket stably on the outer wall of the connecting rod 4, and then rotates the knob 11. The rotation of the knob 11 drives the rotating rod 14 to rotate synchronously through the internal shaft system. The rotating rod 14 then drives the turntable 15 to rotate. The turntable 15 is equipped with a unique limiting groove 16. As the turntable 15 rotates, the limiting groove 16 forms a special trajectory, which drives the sliding column 17 to move. The displacement of the sliding column 17 is transmitted to the transmission column 20 through the mechanical linkage structure, so that the transmission column 20 slides in a specific track. The sliding of the transmission column 20 then drives the limiting disc 12 to slide smoothly inside the moving groove 18. During this process, the second spring 13 is gradually compressed, accumulating elastic potential energy. At the same time, the locking column 3 slowly slides into the connecting rod 4 under this series of transmissions. Once the cylinder head gasket is placed in the precise installation position, the operator releases knob 11. The compressed spring 13 quickly releases its elastic potential energy, generating a strong rebound force that precisely engages the locking pin 3 within the pre-set groove inside the cylinder head gasket, securing it firmly. After securing, the drive rod 2 is activated. As the core of the power transmission, the drive rod 2 drives the connecting rod 4 to move smoothly, precisely delivering the cylinder head gasket into the extrusion cylinder. Once the gasket reaches the designated position, the extrusion cylinder is moved, ensuring a tight fit between the gasket and the inner wall. Utilizing the special scraping structure and friction material on the gasket's surface, residue on the inner wall of the extrusion cylinder is efficiently peeled off during relative movement, achieving deep cleaning of the extrusion cylinder and ensuring efficient and stable subsequent production of the extrusion equipment.

[0043] Working principle: When the extrusion cylinder needs to be cleaned, first place the support frame 1, push the push rod 6 to slide inside the slide groove 7, then the push rod 6 drives the connecting disc 9 to move, compressing the spring 10, and the connecting disc 9 drives the transmission block 19 to move, and then the transmission block 19 drives the locking block 8 to move, so that the support frame 1 can be fixed on the top of the extruder. Then release the push rod 6, and the spring 10 rebounds to drive the locking block 8 to engage inside the extruder for fixation, maintaining stability and preventing shaking during cleaning;

[0044] In addition, the cylinder head gasket needs to be placed on the outer wall of the connecting rod 4. First, turn the knob 11, which drives the rotating rod 14 to rotate. Then, the rotating rod 14 drives the rotating disk 15 to rotate. Then, the rotating disk 15 drives the internal limiting groove 16 to rotate synchronously, which drives the sliding column 17 to move, thereby driving the transmission column 20 to slide. Then, the transmission column 20 drives the limiting disc 12 to slide inside the moving groove 18, compressing the spring 13, so that the locking column 3 can slide into the connecting rod 4. After the cylinder head gasket is placed in the appropriate position, release the knob 11. The spring 13 rebounds and drives the locking column 3 to engage inside the cylinder head gasket for fixation. Then, start the drive rod 2, which drives the connecting rod 4 to move the cylinder head gasket into the extrusion cylinder. Then, move the extrusion cylinder. The cylinder head gasket fits tightly against the inner wall of the extrusion cylinder. The residue is removed through scraping and friction, and the cylinder is cleaned.
