Description

Technical Field

[0001] The invention relates to the technical field of gas cylinder spinning, and in particular to an anti-sticking material scraper device for spinning an aluminum liner gas cylinder and a use method thereof. Background Art

[0002] According to relevant national standards and specifications, the inner liner of a wrapped gas cylinder adopts a seamless structure. In fact, most of them are made of seamless aluminum tubes, and the two ends are formed by hot spinning. At present, a special shape of the spinning wheel is used for spinning of aluminum liner gas cylinders. Since the arc angle of the spinning wheel is relatively special and the contact area with the aluminum tube is small, it is easy for the material to stick to the arc angle during the spinning process, causing the equipment to vibrate during the spinning process. The arc surface after spinning produces uneven pits, and the dents will cause the fibers to be unable to closely combine with the inner liner surface and there will be gaps, which seriously affects the quality of the aluminum bottle winding. There are hidden dangers to the safety of the use of aluminum liner gas cylinders, which may cause serious accidents such as explosions during the use of wrapped gas cylinders.

[0003] The existing spinning wheel can spin finished gas cylinders with aluminum liner, but the spinning effect is not good and there are the following disadvantages: (1) Since the arc of the existing spinning wheel of the aluminum cylinder is small, the contact area with the aluminum tube during the spinning process is small, and it is easy to cause sticking. (2) Since there is no device to remove the sticking on the surface of the spinning wheel, the surface finish of the arc of the gas cylinder after spinning is not good. (3) Due to the sticking on the surface of the spinning wheel, pits appear on the arc surface of the gas cylinder, and the fiber winding cannot fit the arc surface of the aluminum liner, which poses a safety hazard.

[0004] Publication No.: CN116652053A A composite gas cylinder closing device The composite gas cylinder closing device also includes a grinding block and a return spring 5, wherein the grinding block is slidably connected to the support swing arm, the grinding block is in contact with the arc roller, and a return spring 5 is connected between the grinding block and the support swing arm. In this invention, the grinding block is in contact with the arc roller, and the grinding block moves back and forth on the surface of the arc roller to remove the sticky material on the surface, which accelerates the wear of the arc roller and the cleaning effect is poor. Moreover, when the arc roller vibrates, the pressure between the grinding block and the support swing arm changes, the force on the support swing arm is uneven, and the structural reliability and stability are not high.

[0005] In view of this situation, it is necessary to invent an anti-sticking scraper device for aluminum cylinder spinning. Under the premise of ensuring safety, the sticking material on the surface of the spinning wheel can be scraped off in time during the spinning process, the pits on the arc surface can be reduced, the smoothness of the arc surface of the aluminum liner can be improved, the vibration of the equipment during the spinning process can be reduced, and the defects such as pits on the arc surface can be avoided to affect the quality of the aluminum liner. Summary of the invention

[0006] In view of this, the present invention aims to propose an anti-sticking scraper device for aluminum liner gas cylinder spinning and a method of using the same, so as to solve the quality problem of the arc surface pits caused by the inability to safely scrape off the sticky material on the surface of the spinning wheel during the existing spinning process.

[0007] The present application is applied to the technical field of gas cylinder spinning.

The scraper blade acts on the spinning wheel, so that the scraper blade can remove the sticky material on the surface of the spinning wheel during the spinning process. After the spinning process is completed, no grinding is performed. The arc surface of the gas cylinder is smooth and has no pits. At the same time, a gap of 0.1mm is maintained between the scraper blade and the spinning wheel. The spinning wheel and the scraper blade will not collide and break the blade, and the safety performance is relatively high.

[0008] In addition, the present application also defines the scraper blade edge angle α and opening angle β in view of the particularity of the gas cylinder spinning production process, so that the scraper blade can achieve a good balance between cleaning effect, mechanical strength and maintenance convenience.

[0009] The technical solution of the present invention is achieved as follows: a scraper device for anti-sticking material of aluminum liner gas cylinder spinning and a method of using the same, used to remove sticking material on the surface of the spinning wheel, comprising a handle fixing base, a fixing plate and a scraper blade;

[0015] Furthermore, the scraper groove is provided with a cutting edge, the cutting edge of the scraper groove is arranged downward, and the cutting edge angle α of the scraper groove is in the range of 20°-40°.

[0016] Furthermore, the cross-section of the tool handle fixing base is an inverted U-shaped groove, and the tool handle fixing base is provided with a plurality of threaded holes for fixing the fixing plate and adjusting the position of the fixing plate.

[0017] Furthermore, the open end of the tool handle fixing base is connected to the rotating wheel seat by welding.

[0018] Furthermore, the tool handle fixing base is provided with six threaded holes, three threaded holes are used for the tool handle fixing base to mount the fixing plate, and three threaded holes are used for precisely adjusting the position of the fixing plate.

[0019] Furthermore, the fixing plate is arranged in a groove of the knife handle fixing base, and the fixing plate is connected to the knife handle fixing base via an adjusting rod.

[0020] Furthermore, the scraper blade is connected to the fixing plate by bolt connection.

[0021] Another object of the present invention is to disclose a method for using a scraper device for spinning anti-sticking material of an aluminum liner gas cylinder. Based on any of the above-mentioned scrapers for spinning anti-sticking material of an aluminum liner gas cylinder, the specific steps are as follows:

[0038] In order to make the technical means, objectives and effects of the present invention easy to understand, the embodiments of the present invention are described in detail below with reference to specific drawings.

[0039] It should be noted that all the terms used in the present invention to indicate directionality and positionality, such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside", "top", "lower", "lateral", "longitudinal", "center", etc., are only used to explain the relative positional relationship and connection status between the components in a certain state, and are only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0042] One purpose of the present invention is to disclose an aluminum liner gas cylinder spinning anti-sticking scraper device, which is used to remove sticking materials on the surface of a spinning wheel 4, and includes a handle fixing base 1, a fixing plate 2 and a scraper blade 3;

[0043] The knife handle fixing base 1 is arranged on the rotating wheel base 5;

[0044] One end of the fixing plate 2 is connected to the knife handle fixing base 1, and the other end of the fixing plate 2 away from the knife handle fixing base 1 is connected to the scraper blade 3;

[0045] A scraper groove 301 is provided at one end of the scraper blade 3 away from the fixed plate 2 , and the scraper groove 301 is used to clean the sticky material on the arc of the rotary wheel 4 .

[0046] The knife handle fixed base 1 is installed on the rotary wheel seat 5 of the spinning machine as the basic support of the whole device. One end of the fixed plate 2 is connected to the knife handle fixed base 1, and the other end is connected to the scraper blade 3, which plays a connecting and supporting role. The end of the scraper blade 3 with the scraper groove 301 is away from the fixed plate 2. The scraper groove is specially designed so that the sticky material on the surface of the rotary wheel 4 can be removed in real time during the spinning process. The whole device is composed of a few key components, and the assembly and disassembly are convenient and fast. If the scraper blade 3 is worn or damaged, a new part can be quickly replaced without affecting the normal operation of the production line. By adjusting the position and angle of the fixed plate 2, the scraper blade 3 can be adapted to the rotary wheels 4 of different specifications, which is suitable for the production needs of aluminum liner gas cylinders of various sizes. The sticky material cleaning work can be automatically completed without human intervention, which improves production efficiency and reduces the uncertainty caused by human factors.

[0047] This arrangement prevents the gradual accumulation of sticky materials on the rotating wheel 4 to form pits or other defects, ensures the cleanliness and flatness of the surface of the rotating wheel 4, thereby reducing the possibility of defects on the surface of the finished product, improving the overall quality of the aluminum gas cylinder, and helping to maintain stable processing parameters to ensure the consistency and reliability of each product. Regular and effective cleaning of sticky materials can reduce the wear on the rotating wheel 4 and other related parts, reduce the frequency of maintenance, extend the service life of the equipment, reduce the defective rate caused by sticky material problems, and reduce the cost of waste disposal; at the same time, due to the reduction in equipment downtime, production and maintenance costs are indirectly saved.

[0048] Specifically, the cross-sectional arc line of the scraper groove 301 is parallel to the circular arc of the rotating wheel 4 .

[0049] The shape and size of the scraper groove 301 are precisely calculated to ensure that its inner surface can maintain a consistent distance from the outer arc of the rotating wheel 4, which not only ensures that the scraper blade 3 does not cause direct friction damage to the rotating wheel 4, but also effectively removes the material adhering to the rotating wheel 4.

[0050] The cross-sectional arc of the scraper groove 301 is completely consistent with the circular arc of the spinning wheel 4, which can continuously and evenly remove any material adhering to it during the spinning process, avoiding scratches or other forms of damage to the surface of the spinning wheel 4 caused by incorrect angles or uneven pressure, significantly reducing the risk of defects such as pits on the surface of the finished product, improving the overall quality and appearance of the aluminum gas cylinder, and protecting expensive processing equipment.

[0051] Specifically, the arc center of the scraper groove 301 is coaxial with the arc center of the rotating wheel 4 .

[0052] When the center of the scraper groove 301 is in the same plane as the center of the arc of the spinning wheel 4, the distance between the entire scraper blade 3 and the spinning process is kept constant, which ensures that the scraper blade 3 can effectively clean the sticky material in the entire working range, avoiding the problem of incomplete cleaning or excessive wear of some areas due to position deviation.

[0053] This setup sets clear installation standards, facilitates easier adjustment and calibration during installation and maintenance, and ensures optimal results every time you use it.

[0054] Specifically, the gap between the scraper groove 301 and the surface of the rotating wheel 4 is 0.1 mm.

[0055] Through precise adjustment and installation, the distance between the scraper groove 301 and the arc surface of the rotary wheel 4 is always maintained at 0.1mm. This tiny gap prevents the scraper blade 3 from directly rubbing against the surface of the rotary wheel 4, reducing the wear between the two, and ensuring that any material adhering to the surface of the rotary wheel 4 can be effectively removed by the scraper blade 3. In addition, in a high temperature environment, metal parts may undergo thermal expansion. The 0.1mm gap provides a buffer space for this expansion, avoiding excessive contact or jamming caused by temperature changes, and ensuring the stability of the device under different working conditions.

[0056] This arrangement ensures that the scraper blade 3 can act on the surface of the rotating wheel 4 in a consistent manner throughout the entire working range, making various parameters in the processing process, such as rotation speed, pressure, etc., more stable and controllable, improving the consistency and reliability of processing, reducing unnecessary mechanical stress and wear, protecting expensive processing equipment, especially the rotating wheel 4 and other key components, extending their service life, reducing maintenance costs, and significantly reducing the possibility of pits or other defects on the surface of the finished product, thereby improving the overall quality of the aluminum gas cylinder, especially in terms of appearance and performance.

[0057] Specifically, the scraper groove 301 is provided with a cutting edge, and the cutting edge of the scraper groove 301 is arranged downward.

[0058] The blade edge of the scraper groove 301 is used to facilitate the cleaning of sticky materials. The blade edge is directed downward, and the blade edge in the scraper groove faces the surface of the rotary wheel, ensuring that the blade tip is located at the bottom. The scraper blade 3 can directly contact and scrape off the sticky materials on the surface of the rotary wheel 4 during the spinning process. Due to the effect of gravity, the scraped material will fall naturally and will not adhere to the rotary wheel 4 or the scraper blade 3 again, ensuring the cleaning effect. The scraped sticky materials fall to the ground or other collection devices due to gravity, reducing the risk of the sticky materials splashing again or adhering to other parts, and avoiding the possibility of secondary contamination. The blade edge of the scraper blade 3 facing downward can fit the surface of the rotary wheel 4 more stably, ensuring that a consistent contact state can be maintained throughout the entire working range, improving the cleaning efficiency and stability.

[0059] The blade edge directly facing the surface of the rotating wheel 4 can effectively scrape off the sticky material during each rotation, ensuring that the surface of the rotating wheel 4 is clean as new after each processing, significantly improving the cleaning efficiency, avoiding secondary pollution and the problem of re-adhesion of sticky materials, significantly reducing the possibility of pits or other defects on the surface of the finished product, and improving the overall quality of the aluminum gas cylinder.

[0060] Specifically, the blade angle α of the scraper groove 301 is in the range of 20°-40°, preferably 34°.

[0061] For the aluminum liner gas cylinder spinning anti-sticking scraper device, it is recommended to use a blade angle α range of 20° to 40°. This range can achieve a good balance between cleaning effect, mechanical strength and maintenance convenience.

[0062] Specifically, the opening angle β of the scraper groove 301 is in the range of 15°-45°, preferably 30°.

[0063] The opening angle β ranges from 15° to 45°, which is a common opening angle range and is suitable for most application scenarios. The preferred opening of 30° can ensure that the cutting edge effectively contacts the surface of the rotary wheel to achieve efficient cleaning, while maintaining sufficient mechanical strength and reducing the risk of wear and damage. At the same time, the 30° angle also facilitates the installation and removal of the cutting edge, simplifying maintenance work.

[0064] Specifically, the cross section of the tool handle fixing base 1 is an inverted U-shaped groove, and the tool handle fixing base 1 is provided with a plurality of threaded holes for fixing and adjusting the position of the fixing plate 2 .

[0065] The design of multiple threaded holes allows the operator to flexibly adjust the position of the fixed plate 2 according to actual conditions to adapt to different specifications of the rotating wheel 4 or different processing requirements, thereby improving the versatility and flexibility of the equipment. By selecting appropriate threaded holes and fastening with bolts, the angle and height of the fixed plate 2 can be accurately adjusted to ensure that the center of the scraper groove 301 is on the same plane as the center of the arc of the rotating wheel 4, and a tiny gap of 0.1 mm is maintained, thereby achieving the best cleaning effect.

[0066] This setting is easier to adjust and calibrate during installation and maintenance, ensuring optimal results every time it is used, ensuring consistency and reliability in processing, and meeting more diverse production requirements. The convenient installation and disassembly mechanism reduces maintenance time and costs, while also facilitating quick replacement of worn parts, extending the overall service life of the equipment.

[0067] Preferably, the tool handle fixing base 1 is provided with six threaded holes, three threaded holes are used for installing the fixing plate 2 on the tool handle fixing base 1 , and three threaded holes are used for accurately adjusting the position of the fixing plate 2 .

[0068] The arrangement has six threaded holes, three of which are used for fixing and three for adjustment, which not only provides a solid foundation for the entire anti-sticking scraper device, but also makes the installation and removal of the fixing plate 2 more convenient and quick, reducing maintenance time and cost. At the same time, when the scraper blade 3 or other parts need to be replaced, they can also be adjusted quickly without affecting the normal operation of the production line. It can adapt to various specifications of the rotary wheel 4, increasing the versatility and flexibility of the equipment, and is suitable for the production needs of aluminum liner gas cylinders of different models and sizes.

[0069] Preferably, three threaded holes are sequentially arranged on the top surface of the handle fixing base 1 along the length direction, and three threaded holes are sequentially arranged on the side surface of the handle fixing base 1 parallel to the length direction.

[0070] The rectangular plate design provides a larger contact area, enhances the welding strength between the handle fixing base 1 and the rotating wheel seat 5, and ensures the stability of the entire device during operation. The three threaded holes on the top surface allow the fixing plate 2 to be fixed at multiple points, increasing the firmness and reliability of the connection and preventing loosening or displacement under high-speed rotation and high-pressure environments. The three threaded holes on the side allow the operator to fine-tune the angle and height of the fixing plate 2 by adjusting the bolts, ensuring that the center of the scraper groove 301 is on the same plane as the center of the arc of the rotating wheel 4, and maintaining a tiny gap of 0.1 mm, thereby achieving the best cleaning effect.

[0071] This setting enhances the effect of welding fixation, ensures the stability and durability of the entire device under harsh working conditions, reduces failures caused by vibration or impact, and the convenient installation and removal mechanism reduces maintenance time and cost, while also facilitating the rapid replacement of worn parts, extending the overall service life of the equipment.

[0072] Specifically, the open end of the handle fixing base 1 is connected to the roller seat 5 by welding.

[0073] The inverted U-shaped groove design provides a larger installation area, enhances the welding fixation effect, ensures the stability and durability of the entire device under harsh working conditions, and the internal space of the U-shaped groove can easily accommodate and fix the fixing plate 2 and other related components, simplifies the installation process, and provides a good positioning reference.

[0074] The structure of the arrangement is simple, and the position of the fixing plate 2 can be adjusted conveniently as required, which helps to improve the stability and reliability of the device and achieve better use effects.

[0075] Preferably, the knife handle fixing base 1 is arranged adjacent to the rotating wheel 4 , and the length direction of the knife handle fixing base 1 is parallel to the axis of the rotating wheel 4 .

[0076] The arrangement close to the rotating wheel 4 enables the scraper blade 3 to contact and remove the sticky material on the surface of the rotating wheel 4 in real time during the spinning process, avoiding the problem of incomplete cleaning due to excessive distance. The design that the length direction is parallel to the axis of the rotating wheel 4 reduces the potential interference between the scraper device and other components, ensuring the smoothness and safety of the equipment operation. Since the handle fixing base 1 is parallel to the axis of the rotating wheel 4, the fixing plate 2 and the scraper blade 3 can maintain a stable positional relationship within the entire working range, avoiding unstable factors caused by angle deviation. The parallel layout helps to ensure that the center of the scraper groove 301 is on the same plane as the center of the arc of the rotating wheel 4, and maintain a small gap of 0.1 mm, thereby achieving the best cleaning effect.

[0077] This setting not only provides the best working conditions for the entire anti-sticking scraper device, but also enhances its versatility and flexibility, ensures that the scraper blade 3 can be accurately aligned with the surface of the rotating wheel 4, realizes efficient sticky material cleaning, simplifies installation and maintenance work, and improves operational safety and production efficiency.

[0078] Specifically, the fixing plate 2 is connected to the tool handle fixing base 1 through the adjusting rod 6 .

[0079] The adjusting rod 6 is used to abut the fixing plate 2, so that the fixing plate 2 can be firmly mounted on the tool handle fixing base 1, ensuring that it will not loosen or move during the entire working process, thereby enhancing the overall stability of the device. The bolt connection allows the operator to flexibly adjust the position of the fixing plate 2 according to actual needs to adapt to different specifications of the rotating wheel 4 or different processing requirements.

[0080] Specifically, a plurality of adjusting rods 6 are provided, threads are provided on the surface of the adjusting rods 6 , a protrusion is provided at one end of the adjusting rods 6 , and the adjusting rods 6 pass through the threaded holes on the tool handle fixing base 1 and abut against the fixing plate 2 .

[0081] The multiple adjustment rods 6 not only provide a stable foundation for the entire anti-sticking scraper device, but also make the installation and removal of the fixed plate 2 more convenient and quick, reducing maintenance time and cost. At the same time, when the scraper blade 3 or other parts need to be replaced, they can also be adjusted quickly without affecting the normal operation of the production line. It can adapt to various specifications of the rotary wheel 4, increase the versatility and flexibility of the equipment, and is suitable for the production needs of aluminum liner gas cylinders of different models and sizes.

[0082] Preferably, the adjusting rod 6 is a bolt.

[0083] Specifically, the scraper blade 3 is connected to the fixing plate 2 by bolt connection.

[0084] The scraper blade 3 can be fine-tuned by adjusting the bolt to ensure the best cleaning effect, and can be easily disassembled and replaced, simplifying the maintenance and repair process. When the scraper blade 3 is worn or damaged, it can be quickly replaced with a new part, reducing downtime.

[0085] Specifically, the size range of the processed aluminum tube is: outer diameter φ428-φ509mm, aluminum tube wall thickness 6-15mm, aluminum tube length 2000-6000mm.

[0086] The wide range of sizes available allows the device to be used on different production lines, reducing the need for specialized equipment, improving equipment utilization and return on investment, reducing additional costs due to replacement of equipment or tools, reducing overall production costs, and being able to meet the different needs of more customers. It reduces the types of specialized tools and equipment that need to be stocked, simplifies inventory management and maintenance, eliminates the need for frequent equipment replacement or setting adjustments, saves time and labor costs, and improves the overall efficiency of the production line.

[0087] Another object of the present invention is to disclose a method for using a scraper device for spinning anti-sticking material of an aluminum liner gas cylinder. Based on the above-mentioned scraper device for spinning anti-sticking material of an aluminum liner gas cylinder, the specific steps are as follows:

[0088] S1: Fix the tool handle fixing base 1 on the rotating wheel base 5;

[0089] S2: Install the fixing plate 2 and the scraper blade 3, with the scraper groove 301 opening downward, and ensure that after installation, the center of the scraper groove 301 on the scraper blade 3 and the arc center of the rotating wheel 4 are on the same plane;

[0090] S3: Adjust the six bolts on the blade fixing base 1, change the position of the fixing plate 2, and ensure that the scraper groove 301 and the arc of the rotating wheel 4 are exactly matched with a gap of 0.1 mm;

[0091] S4: Manually rotate the rotary wheel 4, so that the circular arc of the rotary wheel 4 and the scraper groove 301 of the scraper blade 3 do not scratch or interfere with each other;

[0092] S5: After spinning, check the edge of the scraper blade 3 in time. If there is any crack or severe wear, replace it with a new scraper blade 3 in time.

[0093] Fix the knife handle fixed base 1 firmly on the rotating wheel seat 5 by welding to ensure its stable position and provide a reliable support platform for subsequent installation. Install the fixed plate 2 on the knife handle fixed base 1 and connect the scraper blade 3 to the fixed plate 2. Make sure that the scraper groove 301 opens downward. After installation, adjust the position so that the center of the scraper groove 301 and the arc center of the rotating wheel 4 are on the same plane to ensure the best cleaning effect. By adjusting the 6 bolts on the knife handle fixed base 1, change the position of the fixed plate 2 to ensure that the scraper groove 301 and the arc of the rotating wheel 4 just match and leave a small gap of 0.1mm. This precise gap setting is the key to achieving efficient cleaning. Check whether there is any scratch or interference before applying pressure to ensure the safety and stability of the equipment during operation and avoid unnecessary mechanical wear. After each spinning, check the edge state of the scraper blade 3 in time. If the edge is found to be cracked or severely worn, a new scraper blade 3 should be replaced in time to maintain the best working condition and cleaning effect of the equipment.

[0094] The method of using the aluminum liner gas cylinder spinning anti-sticking scraper device ensures the precise installation and efficient operation of the equipment through a series of detailed installation and adjustment steps, which not only improves the effect of cleaning sticky materials, enhances the safety and reliability of the equipment, but also simplifies maintenance work, prolongs the service life of the equipment, and optimizes the production process.

[0095] Example 1

[0096] like Figure 2 As shown, the present invention is mainly composed of a tool handle fixing base 1, a fixing plate 2, a scraper blade 3, a scraper blade fixing plate bolt, and a scraper blade fixing bolt. The tool handle fixing base 1 is welded and fixed on the spinning machine rotating wheel seat 5, the fixing plate 2 is fixed to the tool handle fixing base 1 with a scraper blade fixing bolt, and the scraper blade 3 is fixed to the fixing plate 2 with a scraper blade fixing bolt. Finally, the arc center of the scraper blade 3 is aligned with the arc center of the rotating wheel, and is fixed and locked with the scraper blade fixing bolt through the position of the fixing plate 2. After being fixed in this way, it can effectively ensure that the sticky material on the rotating wheel arc is promptly removed by the scraper blade 3 during the spinning process, remove the upper pit of the aluminum liner arc, and ensure the arc spinning quality.

[0097] The specific operation process of the aluminum liner gas cylinder spinning anti-sticking material scraper device of the present invention is briefly introduced as follows through a specific example:

[0098] For aluminum tubes with an outer diameter of φ509mm, the following steps are used to scrape the material during the spinning process:
