Description
Technical Field
[0001] This utility model relates to the field of chipping machine technology, specifically to an automatic blade adjustment device for an intelligent chipping machine. Background Technology
[0002] Caustic soda flakes are caustic soda in flake form. The production of caustic soda flakes involves multiple steps, including evaporation and concentration, solid alkali forming, and flake making. Among these, solid alkali forming and flake making are completed using an intelligent automatic flake forming machine. The molten alkali that has been evaporated and concentrated is temporarily stored in the alkali tank of the flake forming machine. The rotation of the drum of the flake forming machine causes the molten alkali in the alkali tank to adhere to the outer surface of the drum, allowing it to cool and form solid alkali. Then, a scraper is used to scrape the solid alkali off the drum in flakes to produce caustic soda flakes.
[0003] During operation, the drum is subjected to significant torque. Simultaneously, the drum surface is covered with molten alkali at temperatures reaching several hundred degrees Celsius, while the interior contains cooling liquid. This results in extreme temperature variations. Under the influence of torque and temperature differences, the drum surface is prone to deformation, dents, or bulges, causing changes in the distance between the drum surface and the scraper. If the distance is too large, the scraper will struggle to remove the solid alkali, leading to ineffective scraping. If the distance is too small, the scraper is prone to colliding with the drum surface, which can damage or even break the scraper, and also scratch the drum surface. This undoubtedly accelerates corrosion and damage to the drum, severely impacting its service life.
[0004] Therefore, adjusting the distance between the scraper and the drum is very important. However, currently, the scraper is adjusted by directly pushing the cylinder to move linearly. Since the cylinder and the scraper are rigidly connected, it is difficult to control the scraper or the adjustment accuracy is not high. It is very easy for the scraper to advance too much, which can lead to scraper breakage or drum wear, or for the scraper to retreat too much, which can lead to ineffective alkali scraping. Utility Model Content
[0005] The present invention aims to provide an automatic blade adjustment device for an intelligent sheet forming machine, so as to facilitate the position adjustment of the scraper and improve the adjustment accuracy of the scraper.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic blade adjustment device for an intelligent slagging machine, including a scraper, a support, a blade holder, and a blade adjustment mechanism. The blade holder is rotatably connected to the support, the scraper is fixed on the blade holder, and a connecting shaft is fixed on the blade holder. The connecting shaft is located between the scraper and the support. The blade adjustment mechanism includes a drive shaft and a drive source. One end of the drive shaft is hinged to the connecting shaft, and the other end is connected to the drive source. The drive source is used to drive the drive shaft to reciprocate linearly.
[0007] The principle and advantages of this solution are as follows: The scraper is mounted and fixed on the tool holder. When the scraper position needs to be adjusted, the drive source drives the drive shaft to move linearly. The drive shaft actuates the connecting shaft hinged to it. Since the connecting shaft is fixed to the tool holder, and the tool holder is rotatably mounted on the support, the connecting shaft pushes the tool holder to rotate on the support, causing the scraper to move in an arc direction for adjustment. The entire process is converted into a small-angle oscillation of the tool holder through the transmission of the connecting shaft, allowing the scraper to move only a small distance. This makes the scraper adjustment easier to control, more precise, and improves the scraper position adjustment effect. Simultaneously, since the connecting shaft is located between the scraper and the support, when the drive shaft actuates the tool holder through the connecting shaft, the thrust can act directly on the tool holder itself. Compared to the traditional method of using a lever structure (i.e., the driving force acts on one side of the lever fulcrum, and the driven component is located on the other side), this driving method can achieve accurate control of the tool holder, further improving the scraper adjustment accuracy.
[0008] Preferably, as an improvement, an elastic isolation sleeve is fitted on the outer side of the part where the connecting shaft and the drive shaft are hinged, and the two ends of the elastic isolation sleeve are fixed on the drive shaft and the connecting shaft, respectively.
[0009] The above solution uses an elastic isolation sleeve to isolate and protect the hinged area between the connecting shaft and the drive shaft, thereby preventing alkali dust from falling onto the hinged area and affecting the transmission of the structure. The isolation sleeve is elastic, which can avoid hindering the relative movement of the drive shaft and the connecting shaft and is more adaptable to the relative movement of the structure.
[0010] Preferably, as an improvement, the elastic isolation sleeve is a rubber sleeve or a silicone sleeve.
[0011] Through the above solutions, the rubber or silicone sleeves not only have good elasticity, ensuring smooth relative movement between the connecting shaft and the drive shaft, but also have good anti-alkali corrosion effect, resulting in a longer service life for the elastic isolation sleeve.
[0012] Preferably, as an improvement, the tool holder includes a first clamping part rotatably connected to the support and a second clamping part detachably connected to the first clamping part. The first clamping part and the second clamping part have a gap to form a scraper mounting position. One end of the scraper is located in the scraper mounting position, and the other end extends outward from the scraper mounting position and protrudes from the first clamping part and the second clamping part.
[0013] With the above solution, the scraper is clamped and installed by the first clamping part and the second clamping part. When it is necessary to adjust the length of the scraper tip protruding from the first clamping part and the second clamping part, or when it is necessary to replace the scraper, it is only necessary to separate the first clamping part and the second clamping part, adjust the position of the scraper or put in a new scraper, and then reassemble the first clamping part and the second clamping part to fix it, which makes the adjustment and replacement of the scraper more convenient.
[0014] Preferably, as an improvement, the first clamping part, the second clamping part, and the scraper are provided with mounting holes that can be aligned, and fastening bolts are inserted into the mounting holes, so that the first clamping part, the second clamping part, and the scraper are fixedly connected together by the fastening bolts.
[0015] The above solution uses fastening bolts to simultaneously fix the first clamping part, the second clamping part, and the scraper together, thus achieving a better fixation effect for the scraper.
[0016] Preferably, as an improvement, the rear end of the scraper is provided with an adjusting bolt, which is threadedly connected to the scraper holder, and the mounting hole on the scraper is an elongated hole extending along the length of the scraper.
[0017] With the above scheme, the adjusting bolt is used to adjust the length of the scraper extending to the first clamping part and the second clamping part, or after the tip of the scraper is worn or broken, the part originally located in the scraper mounting position is pushed out of the first clamping part and the second clamping part, so that it can be used as a new scraper tip to scrape off caustic soda flakes. The design of the adjusting bolt makes the adjustment operation of the scraper more convenient.
[0018] Preferably, as an improvement, a guide plate is also fixed on the tool holder, the guide plate being located below the tip of the scraper and close to the scraper.
[0019] The above scheme guides the caustic soda flakes scraped off by the scraper, causing them to fall in a fixed direction, which facilitates the collection and packaging of the caustic soda flakes.
[0020] Preferably, as an improvement, the drive source includes an electric cylinder, a reducer, and a motor. The input end of the reducer is connected to the output end of the motor, the output end of the reducer is connected to the input end of the electric cylinder, and the output end of the electric cylinder is connected to the drive shaft.
[0021] The above solution, through the cooperation of electric cylinder, reducer and motor, can reduce the travel of drive shaft per unit time, thereby making the scraper move a smaller distance each time it is adjusted, improving the adjustment accuracy of the scraper and making it easier to control the position of the scraper.
[0022] Preferably, as an improvement, a disc spring is provided between the electric cylinder and the drive shaft.
[0023] The above solution addresses the issue that, due to the typically specialized and expensive material of the drum, it's crucial to minimize maintenance costs by preventing the scraper from scratching it. In this solution, when the scraper is close to or even in contact with the drum surface, it experiences a significant counterforce from the drum surface. This counterforce is transmitted to the drive shaft via the connecting shaft, triggering a disc spring that rapidly retracts the drive shaft. This, in turn, causes the scraper to quickly return to its original position and move away from the drum, thus preventing further scratching. Attached Figure Description

[0027] The following detailed description provides further details on specific embodiments, but the embodiments of this utility model are not limited thereto. Unless otherwise specified, the technical means used in the following embodiments are conventional means well known to those skilled in the art; the experimental methods used are all conventional methods; and the materials and reagents used are all commercially available.

[0029] Example 1
[0030] The automatic blade adjusting device for the intelligent slagging machine in this embodiment has the following structure: Figure 1 As shown, the device includes a scraper 1, a support 2, a blade holder 3, and a blade adjusting mechanism. The blade holder 3 is rotatably connected to the support 2 via a rotating shaft. The scraper 1 is fixed on the blade holder 3. A connecting shaft 4 is fixed on the blade holder 3. The connecting shaft 4 is located between the scraper 1 and the support 2. The blade adjusting mechanism includes a drive shaft 5 and a drive source. One end of the drive shaft 5 is hinged to the connecting shaft 4, and the other end is connected to the drive source. The drive source is used to drive the drive shaft 5 to perform linear reciprocating motion. In this embodiment, the drive source is a cylinder, but other commonly used linear drive mechanisms can also be used instead.
[0031] An elastic isolation sleeve 6 is fitted around the hinged portion of the connecting shaft 4 and the drive shaft 5. The two ends of the elastic isolation sleeve 6 are fixed to the drive shaft 5 and the connecting shaft 4, respectively. In this embodiment, the elastic isolation sleeve 6 is a rubber sleeve; in practical applications, it can also be a silicone sleeve or an isolation sleeve made of other materials with elasticity and corrosion resistance.
[0032] The tool holder 3 includes a first clamping part 7 rotatably connected to the support 2 and a second clamping part 8 detachably connected to the first clamping part 7. The first clamping part 7 and the second clamping part 8 have a gap to form a scraper mounting position. One end of the scraper 1 is located in the scraper mounting position, and the other end extends outward from the scraper mounting position, protruding from the first clamping part 7 and the second clamping part 8. The first clamping part 7, the second clamping part 8, and the scraper 1 are provided with mounting holes that can be aligned. Fastening bolts 9 pass through the mounting holes, and the first clamping part 7, the second clamping part 8, and the scraper 1 are fixedly connected together by the fastening bolts 9. An adjusting bolt 10 is provided at the rear end of the scraper 1, and the adjusting bolt 10 is threadedly connected to the tool holder 3. The mounting hole on the scraper 1 is an elongated hole extending along the length direction of the scraper 1.
[0033] A guide plate 11 is also bolted to the blade holder 3. The guide plate 11 is located at the tip of the scraper 1 (i.e., Figure 1 It is located on the lower side of the upper end shown and close to the scraper 1.
[0034] In this embodiment, during the preparation of caustic soda flakes, the drum 16 rotates, and the scraper 1 scrapes off the solid caustic soda on the drum 16 in flake form.
[0035] When dents or bulges appear on the surface of the drum 16, the position of the scraper 1 needs to be adjusted. At this time, the drive source drives the drive shaft 5 to move horizontally. The drive shaft 5, through the connecting shaft 4, pushes the scraper holder 3 to rotate on the support 2, causing the tip of the scraper 1 to move closer to or further away from the drum 16, thus adjusting the position of the scraper 1. After adjustment, the scraper 1 maintains a suitable distance from the dents or bulges on the drum 16. Then, the scraper 1 scrapes off the solid alkali adhering to the surface of the drum 16 in flakes. The scraped alkali flakes are guided by the guide plate 11 and collected uniformly. The elastic isolation sleeve 6 isolates and protects the connection between the drive shaft 5 and the connecting shaft 4, preventing alkali dust from falling into the connection and causing equipment jamming or corrosion.
[0036] When the position of the depression or bulge on the drum 16 moves away from the scraper 1, the blade distance changes again. At this time, the drive source controls the scraper 1 to move again to adjust the blade distance.
[0037] When it is necessary to adjust the length of the scraper 1 tip protruding beyond the first clamping part 7 and the second clamping part 8, or when the scraper 1 tip is worn or broken, loosen the fastening bolt 9 and push the scraper 1 to move by adjusting the bolt 10. The fastening bolt 9 moves in the elongated hole so that the scraper 1 is partially moved from the first clamping part 7 and the second clamping part 8 to outside the first clamping part 7 and the second clamping part 8. After adjustment, tighten the fastening bolt 9 again.
[0038] Example 2
[0039] The difference between this embodiment and Embodiment 1 lies in the structure of the driving source, such as... Figure 2 As shown, the drive source in this embodiment includes an electric cylinder 12, a reducer 13, and a motor 14. The input end of the reducer 13 is connected to the output end of the motor 14, and the output end of the reducer 13 is connected to the input end of the electric cylinder 12. The output end of the electric cylinder 12 is connected to the drive shaft 5. A disc spring 15 is also provided between the electric cylinder 12 and the drive shaft 5. In practical applications, an elastic isolation sleeve 6 can also be provided at the connection between the electric cylinder 12 and the drive shaft 5 to isolate and protect the connection and prevent alkali dust from falling in.
[0040] In this embodiment, the motor 14 provides initial power, which is then reduced by the reducer 13 and transmitted to the electric cylinder 12. The electric cylinder 12 converts the rotational power into linear power and drives the drive shaft 5 to move laterally. The cooperation of the motor 14, reducer 13, and electric cylinder 12 allows the drive source to drive the drive shaft 5 to achieve a small displacement per unit time, thereby improving the movement accuracy of the scraper 1 during blade adjustment, improving the adjustment accuracy of the scraper 1, and making it easier to control the position of the scraper 1. When the scraper 1 is close to or even in contact with the surface of the drum 16, the scraper 1 is subjected to a large counter-force from the surface of the drum 16. At this time, the scraper 1 transmits the counter-force to the drive shaft 5 through the connecting shaft 4. The drive shaft 5 triggers the disc spring 15 to work, causing the disc spring 15 to drive the drive shaft 5 to retract quickly, thereby allowing the scraper 1 to immediately and quickly reset and move away from the drum 16, thus preventing or preventing the scraper 1 from continuing to scratch the drum 16.
[0041] Example 3
[0042] This embodiment is based on the foregoing embodiments, such as... Figure 3As shown, a push joint is fixedly provided at the rear end of the scraper 1. The push joint includes a first part 17 and a second part 18 that are welded and fixedly connected together. The rear end of the scraper 1 is set perpendicular to the joint of the first part 17 and the second part 18. This ensures that both ends of the scraper 1 have sufficient length to abut against the first part 17 and the second part 18 respectively, thereby ensuring that the push joint can forcefully push the scraper 1. The first part 17 and the second part 18 are symmetrical semi-conical structures, making the push joint as a whole conical shape. A conical sleeve 19 is snapped or welded to one end of the adjusting bolt 10 near the scraper 1. The sleeve 19 is fitted onto the push joint.
[0043] By fitting the sleeve 19 onto the push joint, the adjusting bolt 10 has a larger force area when pushing the scraper 1, making it easier to adjust the scraper 1. Furthermore, since both the sleeve 19 and the push joint are conical, this will not affect the rotation of the adjusting bolt 10.
[0044] Furthermore, since the push joint is formed by combining two symmetrical semi-conical structures, and the rear end of the scraper 1 is perpendicular to the joint of the first part 17 and the second part 18, it is easier to align the scraper 1 when installing the push joint onto it. Simultaneously, when adjusting the scraper 1, the first part 17 and the second part 18 can push the scraper 1 together. The sleeve 19, fitted over the outside of the push joint, also limits the movement of the first part 17 and the second part 18, preventing them from easily separating and allowing for a powerful push on the scraper 1. Moreover, the use of the sleeve 19 and the push joint results in a beveled contact surface, ensuring the scraper 1 is aligned and always located along the central axis of the sleeve 19 and the axis of the adjusting bolt 10, preventing any deviation of the scraper 1.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
