Description

Technical Field

[0001] The invention belongs to the technical field of koji block processing, and in particular relates to a disc koji making machine. Background Art

[0002] In the wine and sauce brewing process, the koji is typically placed into a mold and extruded to form a brick structure, in order to promote the growth and reproduction of microorganisms within the koji, thereby improving its fermentation efficiency. To transform loose koji into dense blocks, a common method currently uses a disc-shaped koji-making machine. This uses a rotating disk to intermittently rotate the mold box. With each rotation, the downward pressure die head above the mold box squeezes the koji within the mold box once, ultimately producing a formed block after several extrusions.

[0003] Considering that the thickness of the koji block and the consistency of the compaction effect of each part of the koji block are directly related to the fermentation efficiency, when the existing disc koji making equipment automatically adds material to the mold box, most of the koji material accumulates in the center of the mold box. On the one hand, this makes it difficult to unify the amount of koji material added to different mold boxes. On the other hand, during the rotation and switching of the mold box, koji material is easily scattered and wasted, further causing differences in the amount of koji material in different mold boxes. More importantly, the koji material presents a wave peak shape in the mold box, which causes the koji material in the middle of the mold box to be more compacted than the koji material in the edge area of the mold box. This series of problems will cause differences in the thickness and density of the koji block after molding, thereby affecting the unification and standardization of the koji block fermentation process conditions. Summary of the Invention

[0007] In some embodiments, the quantitative feeding mechanism also includes a first telescopic driving member, the output end of the first telescopic driving member is upward and connected to the top mold; wherein, the first telescopic driving member is used to drive the top mold down to a set position so that a quantitative cavity for calibrating the bent material is formed inside the calibration box, and is also used to drive the top mold up to the top of the calibration box to push all the bent material in the quantitative cavity into the mold box.

[0008] Exemplarily, a downwardly extending buffer section is provided at the bottom of the feed box, and a gap is formed between the lower end of the buffer section and the turntable; wherein the volume of the buffer section is greater than the sum of the volumes of the calibration box and any mold box.

[0009] For example, the quantitative feeding mechanism also includes a plug plate guard, which is fixedly connected to the support platform, and a second telescopic driving component is provided inside the plug plate guard; wherein the telescopic plug plate is slidably connected inside the plug plate guard and connected to the output end of the second telescopic driving component.

[0010] In one possible implementation, the rotary buckling mechanism also includes a scraper assembly, which is rotatably connected to the support platform and has a plurality of scrapers spaced apart along a circular trajectory, each scraper corresponding to each die respectively; wherein the scraper is used to scrape off the bent material adhered to the die when the die is lifted upward, and to move to the side of the die when the die is pressed downward.

[0011] In some embodiments, the scraper assembly includes: a first slewing support bearing, which is concentrically arranged with the circumferential track and has an inner ring fixed to the support platform; an outer ring of the first slewing support bearing is provided with a connecting plate, and each scraper is provided on the connecting plate; The first rotary driving member is fixed to the lower surface of the supporting platform, and the output end is transmission-connected to the outer ring of the first rotary support bearing, and is used to drive the connecting plate to reciprocate within a set angle range.

[0012] Exemplarily, the rotary buckling mechanism includes: The second slewing support bearing is coaxially sleeved on the periphery of the first slewing support bearing, and the outer ring is fixed to the support platform. The inner ring of the second slewing support bearing is coaxially connected to the slewing disk; The second rotary driving member is fixed to the lower surface of the supporting platform, and the output end thereof is transmission-connected to the inner ring of the second slewing support bearing.

[0013] In some embodiments, a threading hole is provided at the center of the connecting disk, and a first sleeve extending upward is provided around the threading hole; the frame has a loading platform located above the supporting platform, and a second sleeve extending downward is provided at the center of the loading platform, and the second sleeve is rotatably connected to the first sleeve; A plurality of third telescopic drive members are arranged at intervals along a circular track on the loading platform, and the output end of each third telescopic drive member faces downward and is respectively connected to one of the pressing dies; the power pipeline of each third telescopic drive member passes through the first sleeve and the second sleeve and extends to the bottom of the turntable.

[0014] For example, a discharge conveyor is provided on the frame, which is located below the turntable and aligned with the discharge port; one of the pressing dies is provided directly above the discharge port as a discharge die, and the discharge die is used to press the curved block extruded in the die box moving below it onto the discharge conveyor.

[0015] The beneficial effect of the disc koji making machine provided by the present invention is that compared with the prior art, the disc koji making machine of the present invention has a support platform arranged on the frame, which can seal the lower end of the mold box by using the support platform and cooperate with the pressing die to extrude the koji material in the mold box when the turntable drives each mold box to rotate along the circular trajectory; when each mold box moves along the circumferential trajectory in turn to be aligned with the feed port, the koji material in the feed box will fall into the mold box and the calibration box due to the existence of the feed port, and on this basis, the top die is used to push the koji material in the calibration box upward, so that all the koji material enters the mold box aligned above the calibration box and obtains a pre-pressing effect, so that the koji material is evenly filled in the mold box, and then the turntable continues to rotate until the next mold box is aligned with the feed port, and each pressing die is pressed into the mold box below each, thereby realizing further extrusion of the koji material in the mold box, and this process is repeated after the same mold box passes under each pressing die in turn, and the koji material is extruded multiple times, thereby obtaining the final required koji block and being discharged from the discharge port.

[0016] In the above process, since the calibration box has carried out quantitative processing on the koji material entering the mold box, it can ensure that the feeding amount of each mold box is consistent. On this basis, the loose koji material is pre-pressed by the top mold to make the koji material evenly filled in the mold box, thereby ensuring the thickness consistency and density uniformity of the koji blocks formed after multiple extrusions by the die. In addition, since the koji material has been pre-pressed by the top mold, it can avoid the koji material from being scattered outwards due to the movement of the mold box before being squeezed by the die. It can not only avoid the waste problem caused by the koji material being scattered out, but also further avoid the difference in the amount of koji material in the mold box that affects the thickness consistency and density uniformity of the koji block, thereby improving the quality of the koji block molding, which is conducive to the unification and standardization of the koji block fermentation process conditions.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of this application, "multiple" means two or more, unless otherwise specifically defined.

[0021] Please also refer to Figures 1 to 7 The disc koji making machine provided by the present invention is now described. The disc koji making machine includes a frame 10, a quantitative feeding mechanism 20 and a rotary buckling mechanism 30 provided on the frame 10; a support platform 11 is provided on the frame 10, and a feed port 111 and a discharge port 112 are provided on the support platform 11, which are located on the same circular trajectory; The rotary buckling mechanism 30 includes a rotary disk 31 located above the support platform 11, and a plurality of pressing dies 32 spaced apart along a circumferential path above the rotary disk 31. A plurality of mold boxes 311 are spaced apart along the circumferential path of the rotary disk 31. The mold boxes 311 are open at their upper and lower ends, and their lower ends slide against the support platform 11. Each pressing die 32 is used to press into a corresponding mold box 311 that is traveling below it. The quantitative feeding mechanism 20 includes a feed box 21, a calibration box 22 and a top mold 23. The feed box 21 and the calibration box 22 are aligned and arranged on the upper and lower sides of the feed port 111 respectively; the top mold 23 is slidably connected to the calibration box 22 and is used to push the curved material falling from the feed box 21 into the calibration box 22 and move it to the mold box 311 above it.

[0022] It should be noted that the number of mold boxes 311 distributed on the above-mentioned rotary buckling mechanism 30 is related to the number of times the bent material needs to be extruded. For example, if the process requires five extrusion actions on the bent material in each mold box 311, then at least seven mold boxes 311 should be evenly distributed on the turntable 31. Here, considering the layout space requirements, an empty space can be added between the feed port 111 and the discharge port 112, that is, eight mold boxes 311 are set on the turntable, and the angle of rotation of the turntable 31 each time is forty-five degrees, and the feed port 111 and the discharge port 112 are facing one of the mold boxes 311 in the pause state after each rotation. On this basis, after the same mold box 311 is added with the koji material through the quantitative feeding mechanism at the feed port 111, it will be squeezed by the five pressing dies 32 in turn to form a koji block and finally reach the discharge port 112. Since the bottom of the mold box 311 at the discharge port 112 lacks the support of the support platform 11, the pressing die 32 aligned with the discharge port 112 can directly press the koji block out of the mold box 311; this can be repeated to achieve continuous processing of the koji block.

[0023] The disc koji making machine provided in this embodiment is compared with the prior art. The support platform 11 is provided on the frame 10. When the turntable 31 drives each mold box 311 to rotate along the circumferential trajectory, the support platform 11 is used to seal the lower end of the mold box 311 and cooperate with the pressing die 32 to realize the extrusion of the koji material in the mold box 311; when each mold box 311 moves along the circumferential trajectory in sequence to align with the feed port 111, the koji material in the feed box 21 will fall into the mold box 311 and the calibration box 22 due to the existence of the feed port 111. On this basis, the top die 23 is used to push the calibration box 22 upward. The bent material in the mold box 311 is made to enter the mold box 311 aligned above the calibration box 22 and obtain a pre-pressing effect, so that the bent material is evenly filled in the mold box 311, and then the turntable 31 continues to rotate until the next mold box 311 is aligned with the feed port 111, and each pressing die 32 is pressed into the mold box 311 below it, thereby achieving further extrusion of the bent material in the mold box 311. This is repeated in the same mold box 311. After the bent material passes under each pressing die 32 in turn, the bent material undergoes multiple extrusion processes, thereby obtaining the final required bent block and being discharged from the discharge port 112.

[0024] In the above process, since the calibration box 22 performs quantitative processing on the koji material entering the mold box 311, it is possible to ensure that the feed amount of each mold box 311 is consistent. On this basis, the top mold 23 is used to pre-press the loose koji material so that the koji material is evenly filled in the mold box 311, thereby ensuring the thickness consistency and density uniformity of the koji blocks formed after multiple extrusions by the pressure mold 32. In addition, since the koji material has been pre-pressed by the top mold 23, it can avoid the koji material from being scattered outward due to the movement of the mold box 311 before being squeezed by the pressure mold 32. Not only can it avoid the waste problem caused by the koji material being scattered outward, but it can also further avoid the difference in the quantity of the koji material in the mold box 311 and affecting the thickness consistency and density uniformity of the koji block molding, thereby improving the koji block molding quality, which is conducive to the unification and standardization of the koji block fermentation process conditions.

[0025] In some embodiments, see Figure 4 and Figure 5 The rotary disk 31 has a plurality of die openings 312 spaced apart along the circumferential track, and each die box 311 is respectively connected to the bottom of each die opening 312; there is an insertion gap 33 between the feed box 21 and the rotary disk 31; the quantitative feeding mechanism 20 also includes a telescopic plug-in plate 24, which has an insertion state of inserting the insertion gap 33 to seal the feed box 21 and the die opening 312, and an open state of withdrawing the insertion gap 33; in the open state, the feed box 21 is used to fill the mold box 311 and the calibration box 22 moving below it with the bent material; in the insertion state, the top mold 23 is used to push all the bent material in the calibration box 22 into the mold box 311 above it.

[0026] The cam 32 is pressed against the top of the mold 311 and the cam 33 is pressed against the top of the mold 311, thereby preventing the mold 311 from being directly subjected to the downward pressure of the cam 32 and increasing the risk of damage. The slot 33 between the feed box 21 and the rotary disk 31 is used for the insertion of the retractable plug plate 24, so that the lower end of the feed box 21 can be sealed by the retractable plug plate 24. That is, the retractable plug plate 24 is in the slot 33 state during the movement of the rotary disk 31, which can prevent the bent material cached in the feed box 21 from leaking out. When the box 311 is aligned with the feed port 111, the telescopic insert 24 switches to an open state. At this time, the bent material slides in the feed box 21 and fills the mold box 311 and the calibration box 22. After filling, the telescopic insert 24 returns to the plug-in state again, and then the top mold 23 moves upward to push all the bent material in the calibration box 22 into the mold box 311. During this process, the telescopic insert 24 can close the upper end of the mold box 311, thereby preventing the bent material from being pushed out of the mold box 311. After all the bent material is pushed into the mold box 311, the turntable 31 can return to the next rotation.

[0027] The retractable plug plate 24 has three functions in the process of feeding the mold box 311: first, it maintains the plug-in state to block the lower end drop-out port of the feed box 21 when the turntable 31 moves, thereby preventing the bent material in the feed box 21 from leaking out; second, it maintains the plug-in state to block the upper end of the mold box 311 when the top mold 23 moves, thereby providing a barrier for the bent material in the mold box 311; third, after the bent material fills the mold box 311 and the calibration box 22 in the open state, the retractable plug plate 24 can form a flat upper surface in the mold box 311 during the insertion of the insertion gap 33. On the one hand, this can ensure the consistency of the amount of bent material in the center and edge areas of the mold box 311, thereby improving the uniformity of the density of the bent block after subsequent extrusion molding; on the other hand, it can ensure the consistency of the amount of bent material added to the mold box 311 and the calibration box 22 each time, thereby improving the thickness consistency of the bent block after extrusion molding.

[0028] The function of the calibration box 22 is to cooperate with the telescopic plug plate 24 in the plug-in state to enable the mold box 311 aligned with it and its own internal space to form a cavity with a fixed capacity. Therefore, the amount of bent material falling into the cavity each time the telescopic plug plate 24 is opened is consistent, thereby meeting the demand for quantitative feeding. On this basis, since the top mold 23 can avoid the bent material from remaining on the inner wall of the calibration box 22 during the process of sliding upward in the calibration box 22, the consistency of the amount of bent material entering the calibration box 22 each time can be further guaranteed. In addition, since the bent material in the feed box 21 is in a loose state, when After entering the mold box 311 for extrusion, there will be a great change in volume, which is specifically manifested as compression in the thickness direction. The purpose of setting the calibration box 22 and the mold box 311 together for feeding rather than directly feeding into the mold box 311 is to increase the feed amount, and then use the top mold 23 to pre-compress the loose curved material, so that the curved material fills the mold box 311 in a relatively dense state. This can reduce the compression amount of the curved material by the subsequent die 32, which can not only improve the space utilization rate of the mold box 311, but also reduce the downward pressing stroke of the die 32, which is beneficial to improving the movement stability of the die 32 and the processing efficiency of the curved block.

[0029] As a specific embodiment of the quantitative feeding mechanism 20, please refer to Figures 1 to 4 The quantitative feeding mechanism 20 also includes a first telescopic driving member 25, the output end of the first telescopic driving member 25 is upward and connected to the top mold 23; wherein, the first telescopic driving member 25 is used to drive the top mold 23 to descend to a set position so that a quantitative cavity 221 for calibrating the bent material is formed inside the calibration box 22, and is also used to drive the top mold 23 to rise to the top of the calibration box 22 to push all the bent material in the quantitative cavity 221 into the mold box 311.

[0030] The first telescopic drive member 25 can be a telescopic cylinder, a hydraulic cylinder or an electric telescopic cylinder. In order to facilitate the control of the telescopic stroke, an electric telescopic cylinder can be preferably used. By adjusting the telescopic stroke of the first telescopic drive member 25, the position of the top mold 23 driven to descend can be changed, thereby adjusting the volume of the quantitative cavity 221, thereby adjusting the feeding amount, and then obtaining curved blocks of different specifications and thicknesses; when the first telescopic drive member 25 drives the top mold 23 to move downward to the set position, a space for accommodating the curved material falling from the feed box 21 can be formed inside the calibration box 22. Since the position where the top mold 23 is driven to descend by the first telescopic drive member 25 is fixed, this space can be used as a calibration curve for the quantitative cavity 221. When the top mold 23 is flush with the top of the calibration box 22, all the bent materials in the quantitative cavity 221 can be pushed into the mold box 311. In addition, the top mold 23 and the telescopic plug plate 24 in the sealing state jointly extrude the loose bent materials into a block-shaped whole that is consistent with the shape of the inner cavity of the mold box 311. In this way, the extrusion stroke of the bent materials by the subsequent pressing mold 32 can be reduced, and at the same time, the bent materials in the mold box 311 can be avoided from being wasted during the movement of the turntable 31, thereby further ensuring the consistency of the amount of bent materials in the mold box 311.

[0031] In some embodiments, as Figure 3 As shown, a downwardly extending cache section 211 is provided at the bottom of the feed box 21, and a gap 33 is formed between the lower end of the cache section 211 and the turntable 31; wherein, the volume of the cache section 211 is greater than the sum of the volumes of the calibration box 22 and any mold box 311.

[0032] By setting up a buffer section 211 to accommodate the bent material, material breakage can be avoided. At the same time, it is also beneficial to improve the efficiency of the material dropping from the feed box 21 to the quantitative cavity 221 and the mold box 311. On this basis, since the buffer section 211 accommodates more bent material than the total volume of the calibration box 22 and the mold box 311 above it, when the telescopic plug plate 24 is in the open state, the buffer section 211 still has bent material remaining after the bent material fills the quantitative cavity 221 and the mold box 311. At this time, the telescopic plug plate 24 is inserted into the slot 33 to separate the bent material. On the one hand, it can ensure that the bent material fills the mold box 311 and the quantitative cavity 221, ensuring consistent feed amount, thereby improving the consistency of the bent block forming thickness. On the other hand, it can make the bent material form a flat surface at the top of the mold box 311, thereby improving the filling uniformity of the bent material in the mold box 311, and further improving the uniformity of the density of each part of the bent block after extrusion molding.

[0033] Specifically, see Figure 3In this embodiment, the quantitative feeding mechanism 20 also includes a plug-in plate shield 26, which is fixedly connected to the support platform 11, and a second telescopic driving member 27 is provided in the plug-in plate shield 26; wherein the telescopic plug-in plate 24 is slidably connected in the plug-in plate shield 26 and is connected to the output end of the second telescopic driving member 27.

[0034] The second telescopic drive member 27 can specifically be a telescopic cylinder, a hydraulic cylinder or an electric telescopic cylinder. Considering that the power required for the telescopic plug plate 24 is relatively small, a telescopic cylinder can be preferably used. On the one hand, it saves cost and installation space. On the other hand, the telescopic cylinder has an advantage in movement speed, which can increase the speed of switching the telescopic plug plate 24 between the plugged state and the open state, which is beneficial to improving feeding efficiency.

[0035] The provision of the plug plate shield 26 can prevent the second telescopic driving member 27 and the telescopic plug plate 24 from being exposed, which not only avoids the risk of injury to the operator caused by the moving parts, but also can utilize the plug plate shield 26 to provide sliding constraints on the telescopic plug plate 24, thereby improving the movement stability of the telescopic plug plate 24, and avoiding the situation where the telescopic plug plate 24 cannot be accurately inserted into the insertion slot 33 due to vibration caused by unstable connection, thereby ensuring a smooth and stable feeding process.

[0036] For some possible implementations, see Figure 1 and Figure 5 The rotary buckling mechanism 30 also includes a scraper assembly 34, which is rotatably connected to the support platform 11 and has a plurality of scrapers 341 spaced apart along a circular trajectory, each scraper 341 corresponding to each die 32; wherein the scraper 341 is used to scrape off the bent material adhered to the die 32 when the die 32 is lifted upward, and to move to the side of the die 32 when the die 32 is pressed downward.

[0037] Taking into account the stickiness of the koji, the lower surface of the die 32 may stick to the koji when the die 32 is lifted up after squeezing the koji downwards, which will affect the flatness of the lower surface of the die 32, and further cause the die 32 to make the upper surface of the koji uneven during the subsequent extrusion of the koji, affecting the surface flatness of the koji block after it is formed, which is also not conducive to the fermentation efficiency of the koji block. Therefore, in this embodiment, a scraper assembly 34 is provided, and a scraper 341 is used to scrape off the koji adhered to the lower surface of the die 32 each time the die 32 is lifted, thereby ensuring that the die 32 has a flat lower surface before pressing the koji each time, thereby ensuring the surface flatness of the koji block after it is formed, and further ensuring that the density of each part of the koji block after it is formed is uniform and consistent.

[0038] As a specific embodiment of the scraper assembly 34, please refer to Figures 5 to 7The scraper assembly 34 includes a first rotary support bearing 342 and a first rotary driving member 343; the first rotary support bearing 342 is arranged concentrically with the circumferential track and the inner ring is fixed to the support platform 11, the outer ring of the first rotary support bearing 342 is provided with a connecting disk 3421, and each scraper 341 is provided on the connecting disk 3421; the first rotary driving member 343 is fixed to the lower surface of the support platform 11, and the output end is transmission-connected to the outer ring of the first rotary support bearing 342, for driving the connecting disk 3421 to rotate back and forth within a set angle range.

[0039] The rotary support bearing is a large bearing with complex load-bearing capacity. The first rotary support bearing 342 is used as the installation base of the connecting disk 3421, and each scraper 341 is installed on the connecting disk 3421. The outer ring of the first rotary support bearing 342 is driven to rotate by the first rotary drive member 343, such as a motor, thereby driving the connecting disk 3421 to rotate to realize the scraping action of each scraper 341 on the corresponding die 32; considering that the feed box 21 is aligned and arranged above the feed port 111, if the connecting disk 3421 rotates continuously in one direction, the scraper 341 will interfere with the feed box 21. Therefore, the first rotary drive member 343 is used to drive the connecting disk 3421 to perform reciprocating rotational motion within a set angle range. The specific set angle range is suitable for the scraper 341 to swing from one side of the die 32 to the other side.

[0040] Specifically, the output end of the first rotary driving member 343 is provided with a first driving gear 3431 , the outer ring of the first slewing support bearing 342 is provided with a first gear ring, and the first driving gear 3431 is meshed and connected with the first gear ring.

[0041] Please note that Figure 6 and Figure 7 The above-mentioned rotary buckling mechanism 30 also includes a second rotary support bearing 35 and a second rotary driving member 36; the second rotary support bearing 35 is coaxially sleeved on the periphery of the first rotary support bearing 342, and the outer ring is fixed to the support platform 11, and the inner ring of the second rotary support bearing 35 is coaxially connected to the rotary disk 31; the second rotary driving member 36 is fixed to the lower surface of the support platform 11, and the output end is transmission-connected to the inner ring of the second rotary support bearing 35.

[0042] The second rotary support bearing 35 and the first rotary support bearing 342 are identical in structure and differ only in size. Here, the second rotary support bearing 35 has a larger diameter and is mounted on the outer circumference of the first rotary support bearing 342, which can improve space utilization and ensure the compactness of the overall structure. The outer ring of the second rotary support bearing 35 is fixed to the support table, and the inner ring serves as the installation base of the turntable 31. As a result, the inner ring of the second rotary support bearing 35 can be driven to rotate by a second rotary driving member 36, such as a motor, thereby driving the turntable 31 to rotate. Specifically, the output end of the second rotary driving member 36 is provided with a second driving gear 361, and the inner circumferential wall of the inner ring of the second rotary support bearing 35 is provided with a second gear ring, and the second driving gear 361 is meshed with the second gear ring.

[0043] It should be understood that, in this embodiment, the inner ring of the first slewing support bearing 342 serves as the fixed end and the outer ring serves as the rotating end, while the outer ring of the second slewing support bearing 35 serves as the fixed end and the inner ring serves as the rotating end. As a result, the first rotary drive member 343 and the second rotary drive member 36 are both arranged between the outer ring of the first slewing support bearing 342 and the inner ring of the second slewing support bearing 35, thereby improving the compactness of the overall structure.

[0044] In addition, considering the intermittent rotary motion characteristics of the rotary disk 31 of the rotary buckling mechanism 30, in this embodiment, the station detection component 37 is set using the space between the outer ring of the first rotary support bearing 342 and the inner ring of the second rotary support bearing 35.

[0045] Specifically, such as Figure 6 As shown, a station detection assembly 37 is provided on the support platform 11, located between the outer ring of the first slewing support bearing 342 and the inner ring of the second slewing support bearing 35. The station detection assembly 37 includes a first synchronous pulley 371 rotatably connected to the support platform 11, a second synchronous pulley 372 coaxially connected to the second drive gear 361, and a rotation angle sensor connected to the first synchronous pulley 371. The second synchronous pulley 372 and the first synchronous pulley 371 are connected by a timing belt 373. The rotation angle sensor detects the rotation angle of the first synchronous pulley 371, and then the rotation angle of the second synchronous pulley 372 and the second drive gear 361 is obtained by the transmission ratio between the first synchronous pulley 371 and the second synchronous pulley 372. This rotation angle is used to control the start and stop timing of the second rotary drive member 36, thereby ensuring that the second rotary drive member 36 can accurately drive the turntable 31 according to the intermittent motion angle requirements of each mold box 311.

[0046] In some embodiments, such as Figure 3As shown, the center of the connecting plate 3421 is provided with a threading hole, and the connecting plate 3421 is provided with a first sleeve 3422 extending upwardly around the threading hole; the frame 10 has a loading platform 12 located above the supporting platform 11, and the center of the loading platform 12 is provided with a second sleeve 121 extending downwardly, and the second sleeve 121 is rotatably connected to the first sleeve 3422; A plurality of third telescopic drive members 122 are arranged at intervals along a circular trajectory on the loading platform 12, and the output end of each third telescopic drive member 122 faces downward and is respectively connected to one of the pressing dies 32; the power pipeline of each third telescopic drive member 122 passes through the first sleeve 3422 and the second sleeve 121 and extends to the bottom of the turntable 31.

[0047] The center of the connecting disk 3421 is provided with a threading hole that can cooperate with the inner ring of the first rotary support bearing 342 to form a channel for wiring up and down at the center position of the rotary buckling mechanism 30; a loading platform 12 is provided on the top of the frame 10 to install the third telescopic drive member 122. The third telescopic drive member 122 can specifically be a pneumatic cylinder, an oil cylinder or an electric push rod. Considering that the pressure required for the buckling action is relatively large, an oil cylinder can be preferably used. The power of the oil cylinder comes from the pressure of the hydraulic oil, so it needs to be powered by a hydraulic pump station. Considering the stability and compactness of the overall structure, the hydraulic pump station can be integrated on the frame 10 and located below the support platform 11. The hydraulic oil pipe of the hydraulic pump station passes through the first sleeve 3422 and the second sleeve 121 and then extends to the top of the loading platform 12 to connect with each third telescopic drive member 122. This can avoid the power pipeline from being exposed and the phenomenon of power pipeline entanglement during the movement of the rotary disk 31, thereby improving the movement stability of the rotary buckling mechanism 30.

[0048] It is important to understand that Figure 1 In this embodiment, a discharge conveyor 13 is provided on the frame 10, which is located below the turntable 31 and aligned with the discharge port 112; one of the pressing dies 32 is provided as a discharge die 321 directly above the discharge port 112, and the discharge die 321 is used to press the curved block extruded in the mold box 311 moving below it onto the discharge conveyor 13.

[0049] After being squeezed multiple times by each pressing die 32 in sequence, the loose curved material is formed into a dense curved block and reaches the discharge port 112. At this time, the bottom of the curved block loses the support of the support platform 11 due to the existence of the discharge port 112. When the discharge die 321 moves downward and presses into the mold box 311 below it, the formed curved block can be squeezed downward out of the mold box 311, and then fall onto the discharge conveyor 13. The curved block is discharged through the discharge conveyor 13, thereby realizing the full automation of feeding, pressing, forming and discharging, which is beneficial to improving the processing efficiency of the curved block.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
