Description

Technical Field

[0001] This invention relates to the field of discharge angle adjustment technology, and in particular to a discharge device with adjustable scraping force. Background Technology

[0002] In many industrial sectors such as chemicals, printing, and coatings, the conveying and discharging of liquid materials (such as inks and slurries) is a crucial step in the production process, directly impacting production efficiency, finished product quality, and production continuity. Currently, multi-roller conveying and discharging equipment is widely used in the industry for conveying and discharging such liquid materials. This type of equipment achieves stable conveying of liquid materials through the coordinated rotation of multiple sequentially arranged rollers, with the last roller in the conveying direction completing the discharge operation. Due to its advantages such as stable conveying, low material loss, and strong adaptability, it has become one of the core pieces of equipment in the liquid material processing process.

[0003] In existing multi-roller liquid material discharging equipment, the discharging structure typically includes a discharge plate located on the discharge side of the last roller. The end of the discharge plate is tightly fitted to the roller surface. Utilizing the rotation of the roller, the liquid material adhering to the roller surface is scraped off by the scraping action of the discharge plate end against the roller surface. The scraped material is then guided by the discharge plate to complete the discharge process, thus facilitating material collection and connection with subsequent processing steps. This discharging structure is simple in design and has low manufacturing costs, making it widely used in the conveying and discharging of low-viscosity, single-component liquid materials.

[0004] However, in actual production, the properties of liquid materials are affected by various factors such as production process, ambient temperature, and raw material ratio, resulting in significant fluctuations in viscosity. For example, in ink production, differences in the ratio of raw materials from different batches and variations in the uniformity of stirring can lead to significant changes in ink viscosity. In slurry production, adjustments to the solid-liquid ratio and increases or decreases in ambient temperature can alter the viscosity of the slurry, thereby affecting the adhesion strength of the material to the roller surface and the difficulty of scraping.

[0005] For liquid materials of different viscosities, the adhesion force between the discharge plate and the roller surface (i.e., scraping force) needs to be adjusted accordingly to ensure the discharge effect and protect equipment components: When the material viscosity is high, its adhesion to the roller surface is strong. If the adhesion force of the discharge plate is insufficient, the material on the roller surface cannot be completely scraped off, resulting in material waste. The residual material will also accumulate and solidify on the roller surface, affecting the conveying accuracy and discharge quality of subsequent materials, and may even lead to roller surface wear and equipment failure. When the material viscosity is low, its adhesion to the roller surface is weak. If the adhesion force of the discharge plate is too large, on the one hand, it will increase the resistance of the roller rotation and consume more power, and on the other hand, it will aggravate the wear at the end of the discharge plate and shorten the service life of the discharge plate. At the same time, excessive force may also damage the roller surface, affecting the rotational stability of the roller, and thus leading to problems such as leakage and spillage during material conveying.

[0006] Currently, most multi-roller liquid material discharging equipment uses fixed-installation discharge plates. The adhesion between the discharge plate and the roller surface cannot be flexibly adjusted according to changes in material viscosity, limiting its suitability to liquid materials with a single viscosity or very small viscosity fluctuations. When material viscosity changes significantly, operators can only indirectly adjust the adhesion by disassembling the equipment, replacing the discharge plate, or adjusting its installation position. This method is cumbersome, time-consuming, and labor-intensive, severely impacting production efficiency. Furthermore, the adjustment accuracy is low, failing to precisely match the scraping requirements of materials with different viscosities and making it difficult to guarantee the stability of the output quality.

[0007] Therefore, in view of the technical defects of existing multi-roller liquid material discharge equipment, such as the inability to flexibly adjust the discharge plate force, poor adaptability, and the impact on production efficiency and discharge quality, there is an urgent need for a technical solution that can flexibly adjust the contact force between the discharge plate and the roller according to the viscosity of the material, so as to meet the discharge requirements under different working conditions and improve the adaptability and production stability of the equipment. Summary of the Invention

[0008] The purpose of this invention is to provide a discharge device with adjustable scraping force, which can flexibly adjust the scraping force of the material plate to improve the discharge quality and production efficiency.

[0009] To achieve this objective, the present invention adopts the following technical solution: A discharge device with adjustable scraping force, comprising: A frame, on which a discharge plate is installed at the discharge end of the roller; A rotating base is rotatably mounted on the frame. The rotating base includes a connecting end, an adjusting end, and a rotating axis. The connecting end and the adjusting end are located on opposite sides of the rotating axis. The connecting end is connected to the discharge plate. An elastic element, one end of which is connected to the adjusting end; A drive assembly, connected to the other end of the elastic element, is used to stretch the elastic element, causing the adjusting end to rotate about the rotation axis.

[0010] Furthermore, the rotating seat includes: A rotating shaft, which is rotatably mounted on the frame; A lever, which is fixed to the pivot and is perpendicular to the pivot; The connecting end and the adjusting end are located at the two ends of the lever, respectively.

[0011] Furthermore, the connecting end of the lever is provided with a rotating seat, which is connected to the bottom of the discharge plate, enabling the discharge plate to rotate relative to the roller to scrape material by an angle.

[0012] Furthermore, the driving component includes: A lifting seat, wherein the end of the elastic element is connected to the lifting seat; A threaded shaft, wherein the threaded shaft is provided with an external thread, and the lifting seat is provided with a threaded hole adapted to the external thread, and the end of the threaded shaft is threadedly connected to the threaded hole; The threaded shaft is fixed in one of the gears of the gear set at the end away from the lifting seat. The threaded shaft is driven by the gear set and can rotate along its own axis.

[0013] Furthermore, the gear set includes a driving gear and a driven gear, which mesh with each other, and the threaded shaft is coaxially arranged with the driven gear.

[0014] Furthermore, a manual roller is coaxially mounted on the drive gear, and the manual roller is provided with anti-slip texture.

[0015] Furthermore, the lifting seat is provided with an indicator rod that can indicate its height, and the frame is provided with an indicator groove, the end of the indicator rod extending into the indicator groove.

[0016] Furthermore, there are two elastic elements, which are connected side by side between the adjusting end of the lever and the lifting seat, and the two elastic elements are symmetrically arranged about the axis of the threaded shaft.

[0017] Furthermore, it also includes a locking component, the locking component comprising: A mounting base is installed on the frame; A locking rod is slidably disposed within the fixed base, and one end of the locking rod can abut against the rotating base; An abutment spring, sleeved on the locking rod, provides elastic force to the locking rod, causing the end of the locking rod to abut against the rotating seat.

[0018] Furthermore, a handle is also provided on the rotating base.

[0019] The beneficial effects of this invention are: The present invention provides an adjustable scraping force discharge device comprising a frame, a discharge plate, a rotating seat, an elastic element, and a drive assembly. The discharge plate is located at the discharge end of the roller on the frame. The rotating seat is rotatably mounted on the frame and has a rotation axis and connecting ends and adjusting ends located on both sides of the axis. The connecting ends are connected to the discharge plate. One end of the elastic element is connected to the adjusting end, and the other end is connected to the drive assembly. By stretching the elastic element through the drive assembly, the preload of the elastic element can be easily adjusted, thereby flexibly changing the contact pressure between the discharge plate and the roller, achieving continuous adjustment of the scraping force. This adapts to different material characteristics, roller surface conditions, and discharge thickness requirements, thus broadening its applicability and providing a simple and intuitive adjustment operation. Simultaneously, the use of the elastic element as a force transmission component converts the rigid adjustment force into a flexible force applied to the rotating seat, ensuring that the discharge plate and roller surface maintain elastic contact. This effectively avoids roller surface scratches, discharge plate wear, and material crushing damage caused by rigid contact, extending the service life of the components. During operation, the elastic element can absorb the vibration and impact caused by the reaction force of the roller, offset the slight fluctuation displacement of the rotating seat, avoid problems such as material leakage and uneven scraping caused by the sudden increase or decrease of the scraping gap, reduce equipment operating noise, and ensure continuous and stable output.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0025] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0026] Reference Figures 1 to 5 This embodiment provides a discharge device with adjustable scraping force, which is mainly used in the scraping and discharge process of liquid materials such as ink, paint, and slurry at the end of a multi-roller conveyor. It can flexibly adjust the scraping pressure of the discharge plate 11 on the rollers according to the viscosity of the material, the conveying speed, and changes in working conditions. While ensuring that the scraping is clean and without residue, it effectively protects the roller surface and the discharge plate 11, thereby improving the applicability and operational stability of the equipment.

[0027] The adjustable scraping force discharge device includes a frame 1, a discharge plate 11, a rotating seat 2, an elastic element 3, and a drive assembly 4. The whole is mounted on the frame 1. Multiple rollers are set on the frame 1. Liquid materials are conveyed between the multiple rollers. The discharge plate 11 is set at the discharge end of the last roller in the material conveying direction. The discharge plate 11 is attached to the surface of the roller and is used to scrape off the liquid material attached to the roller during the conveying process and guide the material to be discharged stably along the plate surface.

[0028] The discharge plate 11 is mounted on the rotating seat 2. The adjustment mechanism, consisting of the rotating seat 2, the elastic element 3, and the drive assembly 4, can adjust the scraping angle and force of the discharge plate 11.

[0029] Specifically, to achieve continuous adjustment of the scraping force, the rotating seat 2 is rotatably mounted on the frame 1 and connected to the bottom of the discharge plate 11. The rotating seat 2 itself forms a fixed rotation axis 23, and with this rotation axis 23 as the boundary, a connecting end 21 and an adjusting end 22 are formed on both sides of the rotation axis 23, respectively. The connecting end 21 is used to connect to the discharge plate 11, and the adjusting end 22 is connected to one end of the elastic element 3, while the other end of the elastic element 3 is connected to the drive assembly 4. The drive assembly 4 applies a stretching force to the elastic element 3, changing the magnitude of the tension in the elastic element 3, causing the adjusting end 22 to deflect around the rotation axis 23 under the action of the tension, thereby driving the connecting end 21 and the discharge plate 11 to swing synchronously, thus precisely adjusting the clamping force between the discharge plate 11 and the rollers, and achieving controllable adjustment of the scraping force.

[0030] In this embodiment, the rotating seat 2 adopts a lever structure, specifically including a rotating shaft 24 and a lever 25. Both ends of the rotating shaft 24 can be mounted on the frame 1 via bearings. The axis of the rotating shaft 24 is parallel to the axes of multiple rollers, ensuring that when the discharge plate 11 abuts against the roller surface, the contact edge of the discharge plate 11 is flush with the roller surface, reducing material falling through the gap between them. The lever 25 is fixedly installed on the rotating shaft 24, either by bolt connection or welding, and the extension direction of the lever 25 is perpendicular to the axis of the rotating shaft 24, forming a stable rotating structure. The two ends of the lever 25 are a connecting end 21 and an adjusting end 22, respectively, which can smoothly transmit tension during rotation, avoiding force deviation or jamming, making the scraping force adjustment more linear and precise.

[0031] In other embodiments, the rotating seat 2 can be a one-piece structure, that is, the lever 25 and the rotating shaft 24 are integrally formed.

[0032] Reference Figure 3 and Figure 4 A rotating seat 251 is also provided at the connecting end 21 of the lever 25. The rotating seat 251 can be a shaft and hole mating structure. The rotating seat 251 is connected to the bottom of the discharge plate 11. The discharge plate 11 can rotate relative to the connecting end 21 of the lever 25 through the rotating seat 251. The rotating seat 251 can drive the discharge plate 11 to adjust the angle relative to the roller, so that the discharge plate 11 can be set to the optimal scraping angle according to the viscosity of the material, the roller diameter and the discharge direction. This ensures that the material is fully scraped and the residue is reduced, and also avoids material splashing or accumulation due to improper angle, further improving the smoothness of discharge.

[0033] Meanwhile, a handle 26 is provided on the rotating seat 2, which is connected to the rotating shaft 24, making it convenient for operators to manually swing quickly during debugging or emergency situations, so as to achieve coarse adjustment of force and angle and improve the flexibility of on-site operation.

[0034] The drive assembly 4 adopts a threaded lifting and gear transmission structure, including a lifting seat 41, a threaded shaft 42, and a gear set 43. The end of the elastic element 3 furthest from the rotating seat 2 is fixed to the lifting seat 41. The top of the threaded shaft 42 is provided with an external thread 421, and a matching threaded hole 411 is opened on the lifting seat 41. The threaded shaft 42 is connected to the lifting seat 41 by a threaded engagement. The end of the threaded shaft 42 furthest from the lifting seat 41 is fixed to a gear in the gear set 43. Driven by the gear set 43, the threaded shaft 42 can rotate stably around its own axis, thereby causing the lifting seat 41 to rise or fall, changing the stretch of the elastic element 3, and achieving fine adjustment of the scraping force.

[0035] The elastic element 3 is preferably a spring, but it can also be a rubber strip. The elastic element 3 can transform the rigid displacement of the lifting seat 41 into a flexible displacement, which can keep the discharge plate 11 and the roller surface in an adaptive fit. This effectively avoids problems such as scratches on the roller surface, deformation and wear of the discharge plate 11, or material leakage and poor conveying caused by excessive contact force between the end of the discharge plate 11 and the roller surface due to processing errors, assembly deviations, or component wear. At the same time, it can buffer the vibration and impact generated during the rotation of the roller surface and the material conveying process, reduce operating noise, extend the service life of the discharge plate 11 and the roller body, ensure stable and continuous peeling and conveying of materials, and improve the reliability and stability of the whole machine operation.

[0036] The gear set 43 includes a driving gear 431 and a driven gear 432 that mesh with each other. The threaded shaft 42 is coaxially fixed to the driven gear 432 and rotates synchronously. A manual roller 433 is coaxially mounted on the driving gear 431. The diameter of the roller is larger than that of the driving gear 431, and the surface of the roller is provided with anti-slip texture 4331 to facilitate manual rotation by the operator. Through the speed reduction and torque increase effect of the gear set 43, the adjustment process is more effortless and smooth, avoiding over-adjustment or difficulty in control, and significantly improving the adjustment accuracy.

[0037] To enable visualization of the adjustment position, an indicator rod 44 is installed on the lifting seat 41, and a corresponding indicator groove 45 extending along the lifting direction is opened on the frame 1. The length direction of the indicator groove 45 is parallel to the vertical movement direction of the lifting seat 41. The end of the indicator rod 44 extends into the indicator groove 45 and moves synchronously with the lifting seat 41 to ensure that their movements do not interfere with each other. At the same time, the indicator groove 45 also provides guidance for the lifting seat 41 and counteracts the rotation of the lifting seat 41. The operator can intuitively judge the scraping force by the position of the indicator rod 44, which facilitates quick reset to the optimal parameters under different working conditions and improves production consistency.

[0038] In this embodiment, two elastic elements 3 are preferably used. The two elastic elements 3 are arranged side by side between the adjusting end 22 of the lever 25 and the lifting seat 41, and are symmetrically distributed with the threaded shaft 42 as the center. The two elastic elements 3 apply an upward elastic force to the lifting seat 41 from above, and the direction of the elastic force is parallel to the axial direction of the threaded shaft 42. The lever 25 is subjected to balanced force during rotation, avoiding excessive force on one side that may cause swaying, jamming, or uneven scraping, and ensuring that the pressure on the discharge plate 11 in the axial direction of the roller is uniform, and the discharge is continuous and stable.

[0039] It should be noted that in this embodiment, the rotation of the gear is converted into the rotation of the threaded shaft 42 by rotating the roller, and the rotation of the threaded shaft 42 is converted into the vertical linear movement of the lifting seat 41. During this process, the lifting seat 41 is restricted from rotation due to the positioning of the ends of the two elastic elements 3 and the guidance of the indicator groove 45, while allowing the lifting seat 41 to move vertically. The position of the threaded shaft 42 is fixed and can only rotate. Therefore, through the action of the thread, the rotational motion can be converted into the linear motion of the lifting seat 41, thereby controlling the tightness of the discharge plate 11.

[0040] Conversely, when the upper rollers exert a reaction force on the discharge plate 11, causing the lever 25 to rotate slightly, the up-and-down fluctuations of the adjusting end 22 of the lever 25 are transmitted to the elastic element 3 and absorbed by the elastic element 3, preventing the lifting seat 41 from moving up and down. Furthermore, the linear motion of the lifting seat 41 is difficult to convert into the rotational motion of the threaded shaft 42, thus possessing a certain degree of self-locking effect. Therefore, after the height and clearance adjustment of the discharge plate 11 are completed, the position of the lifting seat 41 can be reliably locked, preventing external forces and vibrations from causing the lifting seat 41 to slip on its own, ensuring that the working posture of the discharge plate 11 remains constant over a long period.

[0041] Combination Figure 5 To ensure that the scraping force does not shift during operation, the equipment is also equipped with a locking assembly 5. The locking assembly 5 includes a fixed base 51 fixedly mounted on the frame 1, a locking rod 52 slidably disposed within the fixed base 51, and an abutment spring 53 sleeved on the outside of the locking rod 52. The sliding direction of the locking rod 52 is perpendicular to the rotating shaft 24. The abutment spring 53 continuously applies an elastic thrust to the locking rod 52, ensuring that the end of the locking rod 52 is always pressed against the rotating shaft 24 of the rotating seat 2, limiting its accidental rotation. This ensures that the clamping force of the discharge plate 11 is stable and reliable, unaffected by equipment vibration, material impact, or other factors. When adjustment is required, simply pull the locking rod 52 outward to release the lock; after adjustment, releasing it will automatically reset and lock the device. Operation is simple and positioning is reliable.

[0042] The working principle of the adjustable scraping force discharge device provided in this embodiment is as follows: During actual operation, the rollers continuously rotate and convey liquid materials. The discharge plate 11 closely adheres to the surface of the rollers, scraping the materials off and allowing them to flow out along the plate surface. When the viscosity of the material increases, the tension of the elastic element 3 can be increased through the drive assembly 4, thereby increasing the clamping force of the discharge plate 11 to ensure that high-viscosity materials are thoroughly scraped off, avoiding residue accumulation that could affect subsequent conveying. When the viscosity of the material is low, the clamping force can be appropriately reduced to decrease the rotational resistance of the rollers, reduce power consumption, and simultaneously reduce wear between the discharge plate 11 and the roller surface, extending service life.

[0043] Overall, this equipment, through a structural design combining lever transmission, elastic tension adjustment, gear precision drive, and locking positioning, achieves continuous adjustment, precise control, and stable maintenance of scraping force. It can adapt to the discharge conditions of liquid materials with different viscosities and properties, significantly improving the equipment's versatility and production adaptability. At the same time, it effectively reduces component wear, minimizes material waste, and improves output quality and equipment operational reliability.

Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
