Description

Technical Field

[0001] This utility model relates to the field of scraper clamp technology, and in particular to a stamping pull-out clamp. Background Technology

[0002] In industrial production, processes such as papermaking, printing, and coating widely utilize equipment with roller surfaces. To maintain roller surface cleanliness and process quality, doctor blade clamps are commonly used to fix the doctor blades and remove residue from the roller surface. Traditional doctor blade clamps often employ rigid fixing methods, or while they may have simple lifting and lowering functions, replacing, maintaining, or adjusting the position of the doctor blades is often cumbersome and time-consuming. This requires manual adjustment using tools in multiple locations, increasing worker workload and extending equipment downtime, thus impacting overall production efficiency. Furthermore, traditional clamps struggle to quickly, accurately, and evenly adjust the contact pressure between the doctor blade and the roller surface. Insufficient pressure may lead to incomplete cleaning, while excessive pressure can accelerate wear on both the doctor blade and the roller surface. Utility Model Content

[0003] This utility model relates to a stamped pull-out clamp, which can achieve quick clamping, easy adjustment and a higher degree of automation in the operation of the scraper clamp.

[0004] In a first aspect, this utility model provides a stamping pull-out type fixture, specifically comprising: a roller surface; a scraper holder provided on one side of the roller surface; a pull-out component fixedly connected to the scraper holder by fixing bolts, and a fixture lower pressure plate fixedly connected to the upper end of the pull-out component; a fixture pivot fixedly provided at the middle of the upper end of the fixture lower pressure plate, and loading / unloading airbags and loading airbags respectively provided in the fixture lower pressure plates on the left and right sides of the fixture pivot; a fixture upper pressure plate rotatably mounted on the fixture pivot, and a fixture finger clamp fixedly mounted on the end of the fixture upper pressure plate near the roller surface, with a scraper blade fixedly mounted on the scraper blade in a horizontal state in contact with the roller surface.

[0005] Optionally, the width of the scraper blade is determined according to the width of the roller surface, and it is for full coverage, with the blade facing upward at the end of the scraper blade that contacts the roller surface.

[0006] Optionally, the clamping lower pressure plate has a "U" shaped structure, with the vertical plate at one end of the clamping lower pressure plate that is away from the roller surface being longer than the vertical plate at the other end.

[0007] Optionally, the side of the clamp pivot away from the roller surface is a loading airbag, and the other side is a loading and unloading airbag. When working, the clamp upper pressure plate and scraper blade are pressed down, the external air source is switched to the loading state, and the loading and unloading airbag is de-aired. When not working, the clamp upper pressure plate and scraper blade are raised, the external air source is switched to the unloading state, and the loading airbag is de-aired.

[0008] Optionally, the pull-out assembly includes two concave sliding rails and two convex fixed rails. The concave sliding rails are double-section right-angle bends, and the upper ends of the concave sliding rails are welded to the bottom of the clamping lower pressure plate. The convex fixed rails are U-shaped structures, and the two ends of the convex fixed rails are outward-turned barb structures. The two ends of the convex fixed rails are slidably engaged in the corresponding concave sliding rails, and the convex fixed rails slide between the two concave sliding rails.

[0009] This utility model provides a stamping pull-out type fixture, which has the following beneficial effects: First, a pneumatic actuator consisting of loading and unloading airbags and a clamping pivot enables rapid and automatic switching between the working and non-working states of the scraper blade. This process can be completed simply by switching the loading or unloading state via an external air source, offering rapid response and effortless operation, greatly simplifying the workflow and providing significant convenience for scraper blade replacement and maintenance. It also effectively prevents deformation and wear of the scraper blade caused by prolonged pressure during non-working periods. Second, the unique pull-out assembly, consisting of double-sided concave sliding rails welded to the bottom of the clamping lower plate and convex fixed rails fixed to the scraper holder, allows the entire clamping mechanism to move flexibly and smoothly along a direction parallel to the roller surface. This design allows operators to easily and precisely adjust the axial position of the scraper blade relative to the roller surface, making both initial installation and fine-tuning during the process very convenient. This ensures the effective coverage of the entire roller surface width by the scraper blade, while its barbed structure guarantees stability and limitation during sliding, preventing accidental dislodgement. Furthermore, the U-shaped structure of the clamp's lower pressure plate, especially its longer vertical plate design at the end furthest from the roller surface, not only enhances the overall structural rigidity and stability, providing a reliable mounting base for the airbag and pivot, but also creates ample operating space. Combined with the clamp's finger grippers' precise positioning and secure clamping of the scraper blades, and the optimized arrangement with the blade faces upwards, this ensures that the scraper blades form a uniform, stable, and efficient line contact with the roller surface during operation, significantly improving the scraping effect.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] Please refer to Figures 1 to 5 : A traditional scraper clamp includes: a roller surface 1; a scraper holder 10 is provided on one side of the roller surface 1; a clamp lower pressure plate 9 is fixedly connected to the scraper holder 10 by fixing bolts 8; a clamp pivot 6 is fixedly provided at the upper middle part of the clamp lower pressure plate 9, and loading / unloading airbags 5 and loading airbags 7 are respectively provided in the clamp lower pressure plates 9 on the left and right sides of the clamp pivot 6; a clamp upper pressure plate 4 is rotatably installed on the clamp pivot 6, and a clamp finger clamp 3 is fixedly installed at the end of the clamp upper pressure plate 4 near the roller surface 1, and a scraper blade 2 is fixedly installed on the clamp finger clamp 3, and the scraper blade 2 is in contact with the roller surface 1 in a horizontal state.

[0015] Example: This utility model proposes a stamping pull-out type fixture, including: a roller surface 1; a scraper holder 10 is provided on one side of the roller surface 1; a pull-out component is fixedly connected to the scraper holder 10 by fixing bolts 8, and a fixture lower pressure plate 9 is fixedly connected to the upper end of the pull-out component; a fixture pivot 6 is fixedly provided in the middle of the upper end of the fixture lower pressure plate 9, and loading and unloading airbags 5 and loading airbags 7 are respectively provided in the fixture lower pressure plates 9 on the left and right sides of the fixture pivot 6; a fixture upper pressure plate 4 is rotatably installed on the fixture pivot 6, and a fixture finger clamp 3 is fixedly installed on the end of the fixture upper pressure plate 4 near the roller surface 1, and a scraper blade 2 is fixedly installed on the fixture finger clamp 3, and the scraper blade 2 is in contact with the roller surface 1 in a horizontal state.

[0016] The width of the scraper blade 2 is determined according to the width of the roller surface 1, and it is for full coverage. The blade of the scraper blade 2 is facing upward at the end that contacts the roller surface 1.

[0017] Among them, the clamping lower pressure plate 9 has a "U" shaped structure, and the vertical plate at one end of the clamping lower pressure plate 9 that is away from the roller surface 1 is longer than the vertical plate at the other end.

[0018] Among them, the side of the clamp pivot 6 away from the roller surface 1 is the loading airbag 7, and the other side is the loading and unloading airbag 5. When working, the clamp upper pressure plate 4 and the scraper blade 2 are pressed down, the external air source is switched to the loading state, and the loading and unloading airbag 5 is empty. When not working, the clamp upper pressure plate 4 and the scraper blade 2 are raised, the external air source is switched to the unloading state, and the loading airbag 7 is empty.

[0019] The pull-out component includes two concave sliding rails 11 and two convex fixed rails 12. There are two concave sliding rails 11, which are double-section right-angle bent structures. The upper end of the concave sliding rail 11 is welded to the bottom of the clamping lower pressure plate 9. The convex fixed rail 12 is a "U" shaped structure. The two ends of the convex fixed rail 12 are outward-turned barb structures. The two ends of the convex fixed rail 12 are respectively slidably engaged in the corresponding concave sliding rails 11. The convex fixed rail 12 slides between the two concave sliding rails 11.

[0020] The following further explains and illustrates the function and effect of each structure mentioned above, so that those skilled in the art can better understand the technical solution: The roller surface 1 serves as the surface to be cleaned or treated, and the scraper blade 2 directly contacts it to remove impurities or residues. A scraper holder 10 is provided on one side of the roller surface 1. The scraper holder 10 serves as the supporting base of the overall fixture and is fixedly connected to the fixture lower pressure plate 9 by fixing bolts 8. The fixing bolts 8 ensure that the fixture lower pressure plate 9 is stably installed on the scraper holder 10, preventing displacement during operation. The fixture lower pressure plate 9 adopts a "U"-shaped structure, with a longer vertical plate at the end furthest from the roller surface 1. This design enhances structural rigidity and facilitates the accommodation of other components. A fixture pivot 6 is fixedly provided at the upper center of the fixture lower pressure plate 9. The fixture pivot 6 serves as a rotation fulcrum, allowing the fixture upper pressure plate 4 to rotate around it, thereby realizing the lifting and pressing actions of the scraper blade 2. The clamping lower pressure plates 9 on both sides of the clamping pivot 6 are respectively equipped with loading / unloading airbags 5 and loading airbags 7. The loading / unloading airbag 5 is located on the side closer to the roller surface 1, and the loading airbag 7 is located on the side farther away from the roller surface 1. Controlled by an external air source, when working, the external air source switches to the loading state, the loading airbag 7 is inflated while the loading / unloading airbag 5 is deflated, pushing the clamping upper pressure plate 4 down, so that the scraper blade 2 contacts the roller surface 1; when not working, the external air source switches to the unloading state, the loading / unloading airbag 5 is inflated while the loading airbag 7 is deflated, the clamping upper pressure plate 4 and the scraper blade 2 are lifted, making it easy to replace or maintain. The clamping upper pressure plate 4 is rotatably mounted on the clamping pivot 6, and the clamping finger clamp 3 is fixedly installed on its end close to the roller surface 1. The clamping finger clamp 3 specifically fixes the scraper blade 2, ensuring that the scraper blade 2 is accurately and stably positioned. The scraper blade 2 is designed to fully cover the width of the roller surface 1, with the cutting edge of its end in contact with the roller surface 1 facing upwards, so as to efficiently scrape the material on the roller surface 1.

[0021] In this embodiment, a pull-out assembly is fixedly connected to the scraper holder 10 by fixing bolts 8. The upper end of the pull-out assembly is fixedly connected to the clamping lower pressure plate 9. The pull-out assembly includes two concave sliding rails 11 and two convex fixed rails 12. There are two concave sliding rails 11, which are double-section right-angle bend structures. Their upper ends are welded to the bottom of the clamping lower pressure plate 9 to provide sliding guidance. The convex fixed rail 12 has a "U"-shaped structure, with outward-turned barb structures at both ends, which slide and engage with the corresponding concave sliding rails 11, allowing the convex fixed rail 12 to slide between the two concave sliding rails 11. This pull-out design allows the clamping lower pressure plate 9 to move along the rails, thereby adjusting the position of the scraper blade 2 relative to the roller surface 1. This facilitates installation, disassembly, and fine-tuning, greatly improving maintenance efficiency and operational flexibility, while ensuring the stability and accuracy of the clamp during operation.

[0022] Working principle: In the initial non-working state, the external air source is switched to the unloading state. At this time, the loading and unloading airbag 5 is inflated, while the loading airbag 7 is in a deflated state. The inflated loading and unloading airbag 5 will push up the end of the clamp upper pressure plate 4 around the clamp pivot 6 near the roller surface 1, causing the clamp upper pressure plate 4 to rotate. The end of the clamp with the clamp finger clamp 3 and the scraper blade 2 is lifted, thereby disengaging the scraper blade 2 from contact with the roller surface 1. This state facilitates the replacement, inspection or maintenance of the scraper blade 2, while avoiding deformation or wear of the scraper blade 2 due to prolonged pressure.

[0023] When it is time to start work, the operator can first make a rough adjustment to the overall position of the scraper blade 2 using the pull-out assembly. Specifically, by applying force to the lower pressure plate 9 of the clamp, it causes the double-sided concave sliding rail 11 welded to the bottom to slide relative to the convex fixed rail 12 fixed on the scraper holder 10. The barb structure at both ends of the convex fixed rail 12 engages with the double-sided concave sliding rail 11, ensuring smoothness and limiting the sliding process and preventing it from coming off. After the scraper blade 2 is adjusted to the appropriate working position, the working procedure can be started.

[0024] At this point, the external air source switches to loading mode, and the loading airbag 7 begins to inflate, while the loading / unloading airbag 5 deflates and contracts. The inflated loading airbag 7 acts on the clamping plate 4, forcing it to rotate in the opposite direction around the clamping pivot 6, meaning that the end with the scraper blade 2 is stably pressed against the roller surface 1. The clamping finger clamps 3 ensure that the scraper blade 2 is firmly held and maintains the correct angle, so that the scraper blade 2, with its cutting edge facing upwards, makes full contact with the roller surface 1 and applies uniform pressure, thereby efficiently completing the task of scraping off residues or coatings on the roller surface 1. The entire working process is automated and rapidly responsive through pneumatic control of the scraper blade 2's pressing and lifting, while the pull-out structure provides the equipment with important position adjustment capabilities.

[0026] 2. Where there is no conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other to obtain new embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
