Description

Technical Field

[0001] This utility model belongs to the technical field of curved block processing equipment, specifically relating to an online cleaning mechanism for the surface of a pressing hammer. Background Technology

[0002] In brewing and sauce-making processes, to promote the growth and reproduction of microorganisms in the koji (fermentation starter) and thus improve its fermentation efficiency, the koji is usually extruded into brick-shaped koji blocks using molds. To improve the efficiency of koji block processing, rotary koji-making equipment is currently widely used. This equipment consists of a ring of molds on a rotary mechanism, with a hydraulically driven pressing hammer for each mold. Every time the rotary mechanism rotates, the pressing hammer, which matches the size of the mold, compresses the koji filling the mold. This allows for multiple compressions of the koji within one rotation, resulting in dense koji blocks.

[0003] In actual production, the existing rotary koji-making equipment suffers from a drawback: the surface of the resulting koji blocks often exhibits unevenness. The root cause lies in the koji material's inherent viscosity. When the koji is pressed by the koji-pressing hammer, some material tends to adhere to the hammer surface, causing bulges and affecting the flatness of the koji block surface. Currently, this problem requires periodically scraping off the adhered material. However, this requires machine downtime, impacting production efficiency. Furthermore, the randomness of material adhesion to the hammer makes controlling the scraping frequency difficult; high frequency disrupts normal production, while low frequency exacerbates koji block defects. Therefore, the problem of material adhesion to the koji-pressing hammer has become a pressing issue in the industry. Utility Model Content

[0004] This utility model provides an online cleaning mechanism for the surface of a pressing hammer, which aims to improve the timeliness of scraping off the koji material adhering to the pressing hammer surface, thereby improving the processing efficiency and surface quality of the koji blocks.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An online cleaning mechanism for the pressing hammer surfaces is provided for online cleaning of each pressing hammer surface of a rotary koji-making equipment. The mechanism includes a rotary support assembly and several scraping plates. The rotary support assembly is connected to the support platform of the rotary koji-making equipment, and each scraping plate is spaced apart along the circumferential direction of the rotary support assembly. Each scraping plate corresponds to one pressing hammer surface, and each scraping plate is flush with the pressing hammer surface in the raised state.

[0006] The rotary support assembly is used to drive the scraper to scrape off the material adhering to the surface of the pressing hammer when the pressing hammer is in a raised state. The rotary support assembly is also used to drive each scraper to move to the side of the corresponding pressing hammer to form an avoidance state.

[0007] In one possible implementation, the slewing support assembly includes a slewing bearing, a slewing frame, and a rotary drive; the inner ring of the slewing bearing is fixedly connected to the bearing platform; the rotary drive is fixedly connected to the bearing platform and its output end is connected to the outer ring of the slewing bearing; the slewing frame is fixedly connected to the outer ring, and each scraper plate is connected to the slewing frame.

[0008] In some embodiments, a gear ring is fitted around the outer periphery of the slewing bearing, and the gear ring is fixedly connected to the outer ring; a drive gear is fitted around the output end of the rotary drive component, and the drive gear meshes with the gear ring; wherein, the rotary drive component is used to drive the gear ring to reciprocate within a set angle range through the drive gear.

[0009] For example, the rotating frame includes a sleeve and a face ring. The sleeve is coaxially connected to the top wall of the outer ring, and the inner cavity of the sleeve forms a pipeline channel. The face ring is coaxially connected to the top of the sleeve. Each scraper is spaced along the circumference of the face ring at the outer edge of the face ring.

[0010] For example, the face ring is provided with a pipeline cover, the inner cavity of the pipeline cover is connected to the pipeline channel, the pipeline cover is used to be inserted upward into the wire conduit of the frame of the rotary fermentation equipment, and there is a rotation gap between the pipeline cover and the wire conduit of the frame.

[0011] In some embodiments, the face ring has at least one inspection hole, and each inspection hole can be detachably connected to a cover plate.

[0012] In one possible implementation, the lower end of the sleeve is provided with a connecting flange, which is fixedly connected to the outer ring; wherein, the connecting flange is provided with a number of first reinforcing ribs distributed at intervals along its circumference, and each of the first reinforcing ribs is fixedly connected to the inner circumferential wall of the sleeve.

[0013] In some embodiments, the lower surface of the face ring is provided with a plurality of second reinforcing ribs spaced apart along its circumference, and each second reinforcing rib is fixedly connected to the outer peripheral wall of the sleeve.

[0014] For example, the outer circumference of the face ring is provided with a protective cover, which extends toward the support platform and forms a rotational gap with the support platform.

[0015] For example, the scraper includes a connecting arm and a scraper body. The connecting arm is overlapped and fixed to the upper surface of the rotary support assembly. The scraper body includes a flexible scraper and a rigid support plate. The rigid support plate is connected to the connecting arm and located on the outer periphery of the rotary support assembly. The flexible scraper is attached and fixed to the rigid support plate. The upper end of the flexible scraper is higher than the bending hammer surface in the raised state, and the upper end of the rigid support plate is lower than the bending hammer surface in the raised state.

[0016] The beneficial effects of the online cleaning mechanism for the pressing hammer surfaces provided by this utility model are as follows: Compared with the prior art, in the normal processing of koji blocks by the rotary koji-making equipment, after each pressing hammer surface is pressed downwards and then lifted back to its initial position, the rotary support component drives each scraper plate to rotate. Since the scraper plate is at the same height as the pressing hammer surface at this time, each scraper plate can scrape off its corresponding pressing hammer surface in one pass, thereby promptly removing the koji material adhering to the pressing hammer surface and preventing the pressing hammer surface from being affected by the adhering koji material, thus ensuring its surface flatness. This improves the surface quality of the final shaped blocks. The scraping and cleaning process of the scraping plate on the pressing hammer surface can be synchronized with the mold box repositioning process of the rotary shaped block making equipment. After each scraping and cleaning of the pressing hammer surface, the scraping plate rotates to the side of the pressing hammer surface under the drive of the rotary support component to form a clearance state, which can provide space for the pressing hammer surface to perform the next pressing action. This not only saves the time spent on downtime cleaning, but also allows for cleaning of the pressing hammer surface after each pressing, thus achieving online cleaning of the pressing hammer surface, which is beneficial to improving the shaped block processing efficiency.

[0025] Please refer to the following: Figures 1 to 5 The online cleaning mechanism for the pressing hammer surfaces 10 provided by this utility model will now be described. The online cleaning mechanism for the pressing hammer surfaces 10 is used to clean each pressing hammer surface 10 of the rotary koji-making equipment online. It includes a rotary support assembly 20 and several scraper plates 30. The rotary support assembly 20 is connected to the support platform 40 of the rotary koji-making equipment. Each scraper plate 30 is spaced apart along the circumferential direction of the rotary support assembly 20. Each scraper plate 30 corresponds one-to-one with each pressing hammer surface 10, and each scraper plate 30 is flush with the pressing hammer surface 10 in the raised state.

[0026] The rotary support assembly 20 is used to drive the scraper plate 30 to scrape off the bent material adhering to the bending hammer surface 10 when the bending hammer surface 10 is in the raised state. The rotary support assembly 20 is also used to drive each scraper plate 30 to move to the side of the corresponding bending hammer surface 10 to form an avoidance state.

[0027] It should be noted that the online cleaning mechanism for the pressing hammer surface 10 provided in this embodiment is applied to existing rotary koji-making equipment. The main structure of the rotary koji-making equipment can be combined with... Figure 2 The structure includes a support platform 40, a rotary table 60 that rotates on the support platform 40, a ring of mold boxes 600 arranged in a circular array on the rotary table 60, and multiple pressing mechanisms 70 corresponding to each mold box 600 above the rotary table 60. Each pressing mechanism 70 has a pressing hammer at its lower end, and the lower surface of the pressing hammer is the pressing hammer surface 10. Considering the feeding and unloading of materials into the mold boxes 600, two mold boxes 600 on the rotary table 60 correspond to the feeding and unloading stations respectively, so pressing mechanisms 70 may not be required. For example, if there are eight mold boxes 600 on the rotary table 60, then six pressing mechanisms 70 are required. The rotary table 60 rotates 45 degrees each time, and each rotation of the pressing mechanism 70 squeezes the material in the mold box 600 once. Thus, the material in the same mold box 600 can be squeezed six times during one rotation of the pressing table, ultimately forming a shaped block which is then discharged by the unloading mechanism. Of course, these are all existing technologies and will not be described in detail here.

[0028] Based on the aforementioned rotary koji-making equipment, the center of the rotary table 60 can be hollowed out (the mold box 600 is normally located near the edge of the rotary table 60; most conventional rotary tables 60 are also annular structures with a hollowed-out center) to create a space suitable for installing the rotary support assembly 20. It should be understood that, considering the loading and unloading stations may not have enough space for the scraper plate 30 to rotate through, the rotary support assembly 20 can reciprocate within a set angle range. That is, each time the pressing hammer surface 10 is raised to its initial position, this… The time is when the rotary table 60 rotates. The rotary support assembly 20 uses this time to drive each scraper 30 to scrape and clean along the pressing hammer surface 10. A single scraping action can be a reciprocating cycle, or it can swing from one side of the pressing hammer surface 10 to the other side. After the scraping action is completed, the scraper 30 moves to the side of the pressing hammer surface 10, so as to squeeze the koji material in the mold box 600 on the rotary table 60 after it has rotated past the target angle for the next time. During this process, the rotary koji-making equipment is always in normal operation, thus realizing online scraping and cleaning of each pressing hammer surface 10.

[0029] Compared with the prior art, the online cleaning mechanism for the pressing hammer surface 10 provided in this embodiment, during the normal processing of koji blocks in the rotary koji-making equipment, after each pressing hammer surface 10 is pressed downwards and then lifted upwards to its initial position, the rotary support assembly 20 drives each scraper plate 30 to rotate. Since the scraper plate 30 is at the same height as the pressing hammer surface 10 at this time, each scraper plate 30 can scrape off its corresponding pressing hammer surface 10 once, thereby scraping off the koji material adhering to the pressing hammer surface 10 in a timely manner, avoiding the impact of the adhering koji material on the surface flatness of the pressing hammer surface 10, and thus improving the final obtained koji block. The surface quality; the scraping and cleaning process of the scraper plate 30 on the pressing hammer surface 10 can be synchronized with the rotation and repositioning process of the mold box 600 of the rotary koji-making equipment. After each scraping and cleaning of the pressing hammer surface 10, the scraper plate 30 rotates to the side of the pressing hammer surface 10 under the drive of the rotary support component 20 to form a clearance state, which can provide room for the pressing hammer surface 10 to perform the next pressing action. This not only saves the time spent on downtime cleaning, but also allows the pressing hammer surface 10 to be cleaned after each pressing, thereby realizing online cleaning of the pressing hammer surface 10, which is conducive to improving the processing efficiency of koji blocks.

[0030] As one specific embodiment of the aforementioned slewing support assembly 20, please refer to... Figure 1 and Figure 2 Understandably, the slewing support assembly 20 includes a slewing bearing 21, a slewing frame 22, and a rotary drive component 23; the inner ring of the slewing bearing 21 is fixedly connected to the bearing platform 40; the rotary drive component 23 is fixedly connected to the bearing platform 40 and its output end is connected to the outer ring of the slewing bearing 21; the slewing frame 22 is fixedly connected to the outer ring, and each scraper plate 30 is connected to the slewing frame 22.

[0031] The slewing bearing 21 is a large bearing capable of withstanding comprehensive loads. Here, the inner ring of the slewing bearing 21 is fixed on the bearing platform 40, and its outer ring can serve as the connection base of the slewing frame 22 and rotate under the drive of the rotary drive component 23. This drives the scraping plates 30 connected to the slewing frame 22 to scrape the pressure hammer surface 10. The slewing bearing 21 not only improves the connection stability of the slewing frame 22 and thus enhances the smoothness of the movement of each scraping plate 30, but also has a compact overall structure, making it convenient to use the internal space of the turntable 60 for installation layout.

[0032] In some embodiments, see Figure 1 A gear ring 211 is sleeved on the outer circumference of the slewing bearing 21, and the gear ring 211 is fixedly connected to the outer ring; a drive gear 231 is sleeved on the output end of the rotary drive component 23, and the drive gear 231 meshes with the gear ring 211; wherein, the rotary drive component 23 is used to drive the gear ring 211 to reciprocate within a set angle range through the drive gear 231.

[0033] Please refer to the above-mentioned rotating frame 22 for a specific structural example. Figure 3 and Figure 4 The rotating frame 22 includes a sleeve 221 and a face ring 222. The sleeve 221 is coaxially connected to the top wall of the outer ring, and the inner cavity of the sleeve 221 forms a pipeline channel 2211. The face ring 222 is coaxially connected to the top of the sleeve 221. Each scraper 30 is spaced along the circumference of the face ring 222 at the outer edge of the face ring 222.

[0034] The purpose of the sleeve 221 is to extend into the turntable 60 and be fixedly connected to the outer ring of the turntable bearing 21. At the same time, it can extend upward to support the face ring 222 above the turntable 60, so that the scraper 30 connected to the face ring 222 can scrape and clean the raised pressing hammer surface 10 above the face ring 222, avoiding motion interference between the scraper 30 and the turntable 60.

[0035] Considering that the pressing mechanism 70 of the rotary koji-making equipment is mostly driven by hydraulic cylinders, which can ensure that the pressing hammer 10 can apply sufficient extrusion force to the koji material in the mold box 600, and the power of the hydraulic cylinder (hydraulic pump station) is usually arranged in the space below the rotary table 60, in this embodiment, the inner cavity of the sleeve 221 can be used as the pipeline channel 2211, and the oil pipes, wires and other things used to connect the pressing mechanism 70 can be arranged through the pipeline channel 2211, thereby improving the concealment of the pipeline layout of the whole machine and avoiding the pipelines from being exposed.

[0036] For some possible implementations, please refer to [link / reference]. Figure 3 The face ring 222 is equipped with a pipeline cover 2221. The inner cavity of the pipeline cover 2221 is connected to the pipeline channel 2211. The pipeline cover 2221 is used to insert upward into the frame conduit 50 of the rotary drum making equipment, and there is a rotational clearance between the pipeline cover 2221 and the frame conduit 50. The function of the pipeline cover 2221 is equivalent to a further extension of the pipeline channel 2211. By setting the pipeline cover 2221, the pipeline and wire can be directly concealed from below the rotary table 60 through the pipeline channel 2211 and extended into the frame conduit 50, thereby avoiding the pipeline being directly exposed above the face ring 222. In addition, in order to avoid motion interference between the pipeline cover 2221 and the frame conduit 50, the diameter of the pipeline cover 2221 can be smaller than that of the frame conduit 50, thereby obtaining a rotational clearance between the two and avoiding problems such as rotational wear and friction noise.

[0037] It should be noted that, in this embodiment, as Figure 1As shown, the face ring 222 has at least one inspection hole, and each inspection hole is detachably connected to a cover plate 2222. The cover plate 2222 can be installed on the face ring 222 by screws to cover the inspection hole. When it is necessary to inspect the components below the face ring 222, such as the slewing bearing 21 and the turntable 60, it is only necessary to remove the cover plate 2222 to carry out the operation, which can improve the convenience and efficiency of the inspection work.

[0038] Specifically, in order to improve the structural strength and connection stability of the slewing frame 22, such as Figure 4 As shown, the lower end of the sleeve 221 is provided with a connecting flange 2212, which is fixedly connected to the outer ring; wherein, the connecting flange 2212 is provided with a plurality of first reinforcing ribs 2213 distributed at intervals along its circumference, and each first reinforcing rib 2213 is fixedly connected to the inner circumferential wall of the sleeve 221.

[0039] It should be noted that, since the diameter of the face ring 222 is larger than the diameter of the sleeve 221, most of the area of ​​the face ring 222 is suspended outside the sleeve 221. Since the face ring 222 serves as the mounting base for each scraper plate 30, its structural strength and stability are crucial. Therefore, in this embodiment, a number of second reinforcing ribs 2223 are distributed circumferentially along the lower surface of the face ring 222, and each second reinforcing rib 2223 is fixedly connected to the outer peripheral wall of the sleeve 221. Figure 4 As shown, by setting a second reinforcing rib 2223, support can be provided for the suspended part of the face ring 222, thereby improving the overall structural strength of the face ring 222 and ensuring the stability of the face ring 222 in driving the movement of each scraper plate 30.

[0040] It is important to understand that you should refer to [the relevant documentation / reference]. Figure 4 In this embodiment, a protective cover 2224 is provided around the outer periphery of the face ring 222. The protective cover 2224 extends toward the support platform 40 and forms a rotational gap with the support platform 40. Since the face ring 222 is higher than the support platform 40, there will be a gap between the face ring 222 and the support platform 40, exposing the slewing bearing 21 below the face ring 222. This not only poses a safety hazard of mechanical rotation injury, but also makes it easy for dirt to fall into the slewing bearing 21, affecting the smoothness of the slewing bearing 21's movement. Therefore, the protective cover 2224 is provided to seal the gap between the face ring 222 and the support platform 40. Of course, in order to avoid friction noise between the protective cover 2224 and the support platform 40 when the face ring 222 rotates, a rotational gap is left between the lower end of the protective cover 2224 and the support platform 40, thereby avoiding motion interference problems.

[0041] For example, please refer to Figure 2 and Figure 5Understandably, the aforementioned scraper 30 includes a connecting arm 31 and a scraper body 32. The connecting arm 31 is overlapped and fixed to the upper surface of the rotary support assembly 20. The scraper body 32 includes a flexible scraper 321 and a rigid support plate 322. The rigid support plate 322 is connected to the connecting arm 31 and located on the outer periphery of the rotary support assembly 20. The flexible scraper 321 is attached and fixed to the rigid support plate 322. The upper end of the flexible scraper 321 is higher than the pressing hammer surface 10 in the raised state, and the upper end of the rigid support plate 322 is lower than the pressing hammer surface 10 in the raised state.

[0042] The scraper body 32 can be connected to the outer area of ​​the rotary support assembly 20 by using the connecting arm 31, thereby ensuring that the scraper body 32 can be circumferentially aligned with the bending hammer surface 10. This ensures that when the scraper body 32 moves from one side of the bending hammer surface 10 to the other side based on the rotary motion of the rotary support assembly 20, it can fully contact the entire bending hammer surface 10, thereby improving the cleaning efficiency of the bending hammer surface 10.

[0043] The scraper body 32 is formed by the rigid support plate 322 and the flexible scraper 321 being attached and fixed together. The main function of the rigid support plate 322 is to fix it to the connecting arm 31 and to support the flexible scraper 321. The flexible scraper 321 can form motion interference with the bending hammer surface 10 based on the position of its upper edge. This not only helps to improve the cleanliness of the scraping of the bent material adhering to the bending hammer surface 10 by the flexible scraper 321, but also avoids large friction noise during the scraping process by utilizing its flexibility, thereby reducing the overall operating noise of the machine.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
