Description

Technical Field

[0001] This utility model belongs to the field of curved block processing technology, specifically relating to a curved block processing feeding mechanism. Background Technology

[0002] In the brewing process, the fermentation of koji (fermentation starter) is a crucial step. To improve the fermentation efficiency of the koji, it needs to be extruded into koji blocks. With the widespread use of automated equipment, most wineries now use automated koji block processing equipment to extrude loose koji into brick-shaped blocks. The working principle of existing koji block processing equipment is to fill loose koji into a mold box set on a rotary table in sequence, while each module passes under the pressing head in sequence. The hydraulic cylinder drives the pressing head to extrude the koji in the mold box, thereby obtaining the formed koji blocks.

[0003] The existing koji processing equipment has a drawback: the amount of koji added to the mold cannot be precisely controlled. This leads to inconsistent thickness of the final koji blocks, and the koji is often "popping out" inside the mold, with more koji in the middle and less at the edges. This results in differences in density between the middle and edge areas after the koji blocks are extruded. These differences in thickness and density directly lead to differences in fermentation efficiency between different koji blocks and different parts of the same koji block, ultimately affecting the quality of the brew. In addition, since the koji needs to move to the next station for extrusion after being added to the mold, and the koji is in a loose state inside the mold at this time, some koji inevitably spills out during the movement. This not only causes waste but also further increases the difference in the amount of koji added to different molds, which urgently needs to be addressed. Utility Model Content

[0004] This utility model provides a feeding mechanism for processing curved blocks, which aims to improve the consistency of curved block forming and reduce the waste of curved material spillage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A feeding mechanism for curved block processing is provided, used to sequentially feed materials into a ring of mold boxes arranged in a circular array on the rotary table of a curved block processing equipment. The mechanism includes a feeding box, an inserting assembly, and a pressing assembly. The feeding box is fixed to the frame of the curved block processing equipment and located on the rotation path of the mold boxes. The feeding box is vertically continuous, with its lower end forming an insertion slot with the rotary table. The inserting assembly is fixedly connected to the frame or the feeding box. The inserting assembly has a sealed state where it is inserted into the insertion slot to seal the feeding box, and an open state where it is withdrawn from the insertion slot. The pressing assembly is connected to the frame and has a receiving box at its top aligned vertically with the feeding box. The receiving box is used to connect vertically with the mold box that travels directly below the feeding box to form a pre-pressing cavity. The feeding box feeds materials into the pre-pressing cavity in the open state, and the pressing assembly presses all the curved material falling into the pre-pressing cavity into the mold box in the sealed state.

[0006] In one possible implementation, the top-pressing assembly includes a lifting drive fixedly connected to the frame, with the output end of the lifting drive facing upward and having a top-pressing template provided thereon; a receiving box fixedly connected to the frame or the lifting drive; the top-pressing template slidingly connected to the receiving box; in the sealing state, the lifting drive is used to drive the top-pressing template to rise to be flush with the top of the receiving box; in the open state, the lifting drive is used to drive the top-pressing template to descend to the bottom of the receiving box.

[0007] In some embodiments, the lifting drive includes a telescopic cylinder, a support frame, and a lifting frame; wherein, the telescopic cylinder is vertically fixed to the frame and has a protective cover on its outer periphery; the support frame is disposed on the protective cover and the top is used to connect to the receiving box; the lifting frame is slidably connected to the support frame and connected to the output end of the telescopic cylinder, and a top pressure template is connected to the lifting frame.

[0008] For example, the support frame includes a base plate and two guide columns; wherein, the base plate is fixedly connected to the top wall of the protective cover, and has a clearance hole in the center suitable for the output end of the telescopic cylinder to pass through; the two guide columns are symmetrically arranged on both sides of the clearance hole, the top ends of the two guide columns are connected to the receiving box, and both guide columns are slidably connected to the lifting frame.

[0009] For example, the lifting frame includes a sliding plate, at least two upright plates, and a connecting plate; wherein, two sliding sleeves are provided at intervals on the sliding plate, and the two sliding sleeves are respectively fitted onto one of the guide columns, and the center of the sliding plate is connected to the output end of the telescopic cylinder; each upright plate is provided at intervals on the sliding plate and is suitable to extend into the receiving box together; the connecting plate is fixedly connected to the top of each upright plate, and a top pressure template is attached and fixed to the connecting plate.

[0010] In one possible implementation, the insert assembly includes a telescopic drive and an insert plate; the telescopic drive is fixed to the frame along the radial direction of the rotary table; the insert plate is fixedly connected to the output end of the telescopic drive and is horizontally aligned with the insert slot; wherein, when the telescopic drive drives the insert plate to insert into the insert slot, it forms an inserted closed state, and when the telescopic drive drives the insert plate to withdraw from the insert slot, it forms an open state.

[0011] In some embodiments, the insert assembly further includes a housing fixed to the frame, a telescopic drive component fixedly connected inside the housing, and a guide rod slidably connected to the side of the telescopic drive component inside the housing, the guide rod being connected to the insert plate.

[0012] For example, the end edge of the insert plate opposite to the telescopic drive member has a chamfer.

[0013] For example, the bottom edge of the feed box is covered with wear-resistant strips, and when in the insertion and sealing state, the upper and lower surfaces of the insert plate are respectively attached to the wear-resistant strips and the rotary table.

[0014] In some embodiments, at least one side wall of the feed hopper is provided with a viewing window.

[0015] The beneficial effects of the curved block processing feeding mechanism provided by this utility model are as follows: Compared with the prior art, in the curved block processing feeding mechanism of this utility model, the rotary table of the curved material processing equipment drives each mold box distributed in a circular array to pass under the feeding box in sequence. When each mold box travels to the bottom of the feeding box, it is aligned with the receiving box to form a pre-compression cavity. At this time, the inserting component is pulled out of the insertion slot to form an open state. The loose curved material in the feeding box can slide down into the feeding box to fill the pre-compression cavity. Then the inserting component is inserted into the insertion slot to form a sealing state, thereby sealing the lower end of the feeding box and the upper end of the pre-compression cavity. At this time, the pressing component pushes the curved material falling into the receiving box upward, so that the loose curved material gradually becomes dense and enters the mold box.

[0016] Throughout the process, the action of switching the insert component from an open state to a sealed state not only ensures that the koji material forms a flat top surface within the mold box, but also guarantees a consistent amount of koji material falling into the pre-compression chamber each time. This ensures, on the one hand, the consistent thickness of the koji blocks extruded into each mold box, and on the other hand, the consistent density of the center and edges of the same koji block after extrusion, thereby improving the consistency of koji block formation and solving the problem of differences in fermentation efficiency between different koji blocks and different parts of the same koji block, which is beneficial to improving the quality of brewing. Since the koji material can be pre-compressed by the top pressure component after entering the pre-compression chamber, thus making the koji material denser, it can prevent the koji material from spilling outwards during the movement of the mold box with the rotary table. This not only reduces the waste of koji material spillage, but also avoids the difference in the amount of koji material caused by spillage, further improving the consistency of koji block formation.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please refer to the following: Figures 1 to 6 The present invention provides a feeding mechanism for curved block processing. This feeding mechanism is used to sequentially feed materials into a ring of mold boxes 100 arranged in a circular array on the rotary table 10 of the curved block processing equipment. It includes a feeding box 20, an inserting assembly 30, and a pressing assembly 40. The feeding box 20 is fixed to the frame of the curved block processing equipment and is located on the rotation path of the mold box 100. The feeding box 20 is vertically continuous, and its lower end forms an insertion slot 200 with the rotary table 10. The inserting assembly 30 is fixedly connected to the frame or the feeding box 20, and the inserting assembly 30 has an insertion slot 200. The machine has a sealed state for the feed box 20 and an open state for the insertion slot 200 to be pulled out; the top pressing assembly 40 is connected to the frame and has a receiving box 41 at the top that is vertically aligned with the feed box 20. The receiving box 41 is used to connect vertically with the mold box 100 that travels to the bottom of the feed box 20 to form a pre-pressing cavity 411; wherein, the feed box 20 is used to feed material into the pre-pressing cavity 411 when it is in the open state, and the top pressing assembly 40 is used to press all the material falling into the pre-pressing cavity 411 into the mold box 100 when it is in the sealed state.

[0027] The curved block processing feeding mechanism provided in this embodiment is used to work in conjunction with the rotary table 10 of the curved block processing equipment to perform the rotary switching operation. The specific working process is as follows:

[0028] The rotary table 10 of the material processing equipment drives the various mold boxes 100 distributed in a circular array to pass under the feeding box 20 in sequence. When each mold box 100 travels to the bottom of the feeding box 20, it aligns with the receiving box 41 to form a pre-compression cavity 411. At this time, the inserting component 30 is pulled out of the insertion slot 200 to form an open state. The loose material in the feeding box 20 can slide down into the feeding box 20 to fill the pre-compression cavity 411. Then the inserting component 30 is inserted into the insertion slot 200 to form a sealing state, thereby sealing the lower end of the feeding box 20 and the upper end of the pre-compression cavity 411. At this time, the pressing component 40 pushes the material falling into the receiving box 41 upward, so that the loose material gradually becomes dense and enters the mold box 100. During this process, the other stations of the rotary table 10 squeeze the pre-compressed material in other mold boxes 100 into blocks, which can ensure the smoothness and continuity of the whole machine operation.

[0029] When all the loose material in the pre-compression chamber 411 enters the mold 100 directly below the feed box 20, and the other molds 100 have completed extrusion or other actions at other stations, the rotary table 10 starts to rotate and switch stations. During this process, since the insert assembly 30 is in the inserting and sealing state, the loose material in the feed box 20 will not fall. Moreover, since the material in the mold 100 has been pre-compressed, it has a flat and dense surface, so it will not spill out of the mold 100 during the movement. By repeating the above process, material can be added to each mold 100 sequentially for pre-compression.

[0030] Compared with the prior art, the feeding mechanism for koji block processing provided in this embodiment, by switching the insert component 30 from an open state to an inserted and sealed state, not only enables the koji material to form a flat surface in the mold box 100, but also ensures that the amount of koji material falling into the pre-compression chamber 411 is consistent each time. This ensures that the thickness of the koji material extruded into koji blocks in each mold box 100 is consistent, and also ensures that the density of the middle and edges of the same koji block is consistent after extrusion, thereby improving the consistency of koji block forming and solving the problem of differences in fermentation efficiency between different koji blocks and different parts of the same koji block, which is beneficial to improving the quality of brewing. Since the koji material can be pre-compressed by the top pressure component 40 after entering the pre-compression chamber 411 to make the koji material dense, it can avoid the situation where the koji material spills outward during the movement of the mold box 100 with the rotary table 10. This not only reduces the waste of koji material spillage, but also avoids the difference in the amount of koji material caused by spillage, further improving the consistency of koji block forming.

[0031] In some embodiments, see Figure 3 and Figure 5 The top-pressing assembly 40 includes a lifting drive 42 fixedly connected to the frame, with the output end of the lifting drive 42 facing upward and equipped with a top-pressing template 424; a receiving box 41 fixedly connected to the frame or the lifting drive 42; the top-pressing template 424 slidingly connected to the receiving box 41; in the sealing state, the lifting drive 42 is used to drive the top-pressing template 424 to rise to be flush with the top of the receiving box 41; in the open state, the lifting drive 42 is used to drive the top-pressing template 424 to descend to the bottom of the receiving box 41.

[0032] The top-pressing module matches the cross-sectional shape of the inner cavity of the receiving box 41, and it is slidably connected inside the receiving box 41, which is equivalent to the bottom of the receiving box 41. When the mold box 100 and the feeding box 20 are vertically aligned, the lower end of the mold box 100 and the upper end of the receiving box 41 form a state of vertical contact or near contact, so that the inner cavity of the receiving box 41 and the inner cavity of the mold box 100 together form the pre-pressing cavity 411. At this time, the inserting assembly 30 switches from the inserted and sealed state to the open state, and the feeding box 20... After the loose material in the 0th cavity falls and fills the pre-compression cavity 411, the insert assembly 30 returns to the insertion and sealing state. Then, the lifting drive 42 drives the top pressing template 424 to move upward. When the top pressing template 424 moves to the top of the receiving box 41, it can press all the material inside the receiving box 41 into the mold box 100. Then, the rotary table 10 drives the mold box 100 to the next station. At the same time, the top pressing template 424 is driven by the lifting drive 42 to descend back to the initial position.

[0033] It should be understood that since the top pressing template 424 is always at the same position (i.e., the initial position) at the bottom of the receiving box 41 when the feeding box 20 feeds material into the pre-compression chamber 411, the feeding amount of the pre-compression chamber 411 can be kept consistent each time. Moreover, since the feeding box 20 and the pre-compression chamber 411 form a single cavity that runs vertically through each other when the inserting component 30 is in the open state, the loose curved material can be inserted when the inserting component 30 is inserted into the inserting slot 200, and the feeding box 20 and the pre-compression chamber 411 can be sealed at the same time. Therefore, the inserting component 30 can ensure that the loose curved material forms a flat upper surface in the mold box 100. After pre-compression on this basis, the thickness and density of the curved material can be kept consistent at different positions in the mold box 100. At the same time, the risk of spillage caused by the protrusion of the curved material added in the mold box 100 can be avoided.

[0034] It should be noted that in this embodiment, the feed amount of the pre-compression chamber 411 can be adjusted by adjusting the lower limit position of the lifting drive component 42, that is, adjusting the initial position of the top pressure template 424, thereby realizing the adjustment of the forming thickness of the curved block as needed, thus meeting the requirements of different forming processes of curved blocks.

[0035] As one specific embodiment of the aforementioned lifting drive component 42, please refer to Figure 3 The lifting drive component 42 includes a telescopic cylinder 421, a support frame 422, and a lifting frame 423. The telescopic cylinder 421 is vertically fixed to the frame and has a protective cover 4211 on its outer periphery. The support frame 422 is mounted on the protective cover 4211 and its top is used to connect to the receiving box 41. The lifting frame 423 is slidably connected to the support frame 422 and connected to the output end of the telescopic cylinder 421. A top pressing template 424 is connected to the lifting frame 423.

[0036] The telescopic cylinder 421 can be electrically telescopic, pneumatically telescopic, or hydraulically telescopic. Here, an electrically telescopic cylinder 421 is preferred, thereby avoiding dependence on high-pressure air sources and hydraulic pump stations. The protective cover 4211 on the outer periphery of the telescopic cylinder 421 serves two purposes: firstly, to prevent the telescopic cylinder 421 from being exposed, and secondly, to use the protective cover 4211 as an installation base to fix the receiving box 41. Specifically, the receiving box 41 is fixed to the top of the support frame 422 set on the protective cover 4211. At the same time, the lifting frame 423 is slidably connected on the support frame 422. On this basis, the top pressing template 424 is installed on the lifting frame 423. The sliding guide of the lifting frame 423 by the support frame 422 can improve the movement stability of the top pressing template 424 and avoid uneven force on the top pressing template 424, which would cause movement jamming.

[0037] Specifically, please refer to Figure 3 In this embodiment, the optional structure of the support frame 422 is as follows: the support frame 422 includes a base plate 4221 and two guide columns 4222; wherein, the base plate 4221 is fixedly connected to the top wall of the protective cover 4211, and has a clearance hole in the center suitable for the output end of the telescopic cylinder 421 to pass through; the two guide columns 4222 are symmetrically arranged on both sides of the clearance hole, the top ends of the two guide columns 4222 are connected to the receiving box 41, and both guide columns 4222 are slidably connected to the lifting frame 423.

[0038] The base plate 4221, the two guide columns 4222 and the receiving box 41 together form a rigid frame structure, which is beneficial to improving the overall structural strength. At the same time, the two guide columns 4222 can be used as the installation base for the lifting frame 423. The telescopic cylinder 421 passes through the clearance hole and connects to the lifting frame 423, thereby driving the lifting frame 423 to slide up and down along the two guide columns 4222. The overall structure is simple and compact, which can ensure the stability of the lifting movement of the lifting frame 423, thereby improving the smoothness of the movement of the top pressure template 424.

[0039] Optionally, please refer to Figure 3In this embodiment, the lifting frame 423 includes a sliding plate 4231, at least two upright plates 4233, and a connecting plate 4234. The sliding plate 4231 is provided with two sliding sleeves 4232 at intervals, and the two sliding sleeves 4232 are respectively sleeved on one of the guide columns 4222. The center of the sliding plate 4231 is connected to the output end of the telescopic cylinder 421. Each upright plate 4233 is provided at intervals on the sliding plate 4231 and is suitable to extend into the receiving box 41 together. The connecting plate 4234 is fixedly connected to the top of each upright plate 4233, and a top pressure template 424 is attached and fixed on the connecting plate 4234.

[0040] The sliding sleeve 4232 on the slide plate 4231 forms a sliding fit with the guide post 4222, which not only ensures smooth and easy sliding, but also improves the connection stability. The connecting plate 4234 is supported above the slide plate 4231 by two upright plates 4233, which ensures that the top pressing template 424 attached to the connecting plate 4234 can extend into the receiving box 41, avoiding motion interference between the slide plate 4231 and the receiving box 41, thereby improving the stability of the movement of the telescopic cylinder 421 driving the lifting frame 423 and then driving the top pressing template 424.

[0041] As one specific embodiment of the above-mentioned insert assembly 30, please refer to Figure 2 and Figure 4 The insert assembly 30 includes a telescopic drive 31 and an insert plate 32. The telescopic drive 31 is fixed to the frame along the radial direction of the rotary table 10. The insert plate 32 is fixedly connected to the output end of the telescopic drive 31 and is horizontally aligned with the insert slot 200. When the telescopic drive 31 drives the insert plate 32 to insert into the insert slot 200, it forms a sealed state. When the telescopic drive 31 drives the insert plate 32 to withdraw from the insert slot 200, it forms an open state.

[0042] The telescopic drive component 31 can be a telescopic cylinder, a telescopic hydraulic cylinder, or an electric telescopic rod. The telescopic drive component 31 drives the insert plate 32 to insert into the slot 200 to block the lower end of the feed box 20 and the upper end of the mold box 100, thus forming a sealing state. When the telescopic drive component 31 retracts, it drives the insert plate 32 to pull away from the slot 200, so that the loose material in the feed box 20 can slide freely into the top pressure cavity. The overall structure is simple and compact, and it can ensure the reliability of the sealing of the feed box 20 by the insert plate 32, and avoid material leakage at the lower end of the feed box 20 during the movement of the mold box 10 driven by the rotary table 10.

[0043] For some possible implementations, please refer to [link / reference]. Figure 2 The insert assembly 30 also includes a housing 33 fixed to the frame, a telescopic drive 31 fixedly connected inside the housing 33, and a guide rod 34 slidably connected to the side of the telescopic drive 31 inside the housing 33, the guide rod 34 being connected to the insert plate 32.

[0044] By setting the housing 33, the insertion assembly 30 can be prevented from being exposed, which not only ensures the neatness of the overall appearance, but also avoids the risk of injury to the operator from moving parts; on this basis, by setting the guide rod 34 inside the housing 33, the insertion plate 32 can be connected together with the output end of the telescopic drive component 31 using the guide rod 34, thereby improving the movement stability of the insertion plate 32.

[0045] Based on the above, in order to improve the smoothness of insertion of the insert plate 32 into the insertion slot 200, such as Figure 6 As shown, the end edge of the insert plate 32 facing away from the telescopic drive member 31 is provided with a chamfer 321. Considering the risk of loose material leaking out of the insert 200 after the insert plate 32 is withdrawn, the width of the insert 200 should be as small as possible. In order to ensure that the insert plate 32 can be stably inserted into the insert 200, the edge of the insert plate 32 is provided with a chamfer 321. This ensures that the end of the insert plate 32 is thinner, thereby ensuring that the insert plate 32 can be inserted into the insert 200 even if there is a certain vertical deviation during movement, thus improving the operational stability.

[0046] It should be noted that, as Figure 1 As shown, in this embodiment, at least one side wall of the feed box 20 is provided with a viewing window 22. By setting the viewing window 22, the material level in the feed box 20 can be observed at any time, avoiding the situation where the material level in the feed box 20 is too low, resulting in the pre-compression chamber 411 not being able to fill the loose material, thereby ensuring the continuity of the whole machine operation.

[0047] In some embodiments, such as Figure 3 As shown, the bottom edge of the feed box 20 is covered with a wear-resistant strip 21. In the insertion and sealing state, the upper and lower surfaces of the insert plate 32 are respectively in contact with the wear-resistant strip 21 and the rotary table 10. In order to improve the sealing performance of the insertion plate 32 and the insertion gap 200 and reduce the leakage of curved material, the upper and lower surfaces of the insert plate 32 need to be in close contact with the lower end of the feed box 20 and the disc surface of the rotary table 10. At the same time, in order to avoid the insert plate 32 from wearing down the end face of the feed box 20, the lower end of the feed box 20 is covered with a wear-resistant strip 21. The wear-resistant strip 21 can be made of polytetrafluoroethylene.

[0048] 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.
