Description

Technical Field

[0001] This utility model relates to the fields of food brewing and environmental protection technology, specifically to a folding unit. Background Technology

[0002] In the traditional soy sauce pressing process, the material needs to be wrapped in filter cloth before being fed into the pressing device. However, for solid materials (materials with low moisture content and no or very low fluidity), directly wrapping the material in filter cloth for pressing results in a low juice yield.

[0003] The existing method of folding filter cloth involves evenly spreading the material on a large, unfolded filter cloth, placing a smaller filter cloth on top of the spread material, and then overlapping the four sides of the large filter cloth with the smaller filter cloth to wrap the material, forming a long strip or square filter cloth block wrapped with the material. This process is repeated to stack several identical filter cloth blocks along their height, and finally, the stacked filter cloth blocks are fed into a pressing device to extract the juice.

[0004] Among the above methods of fabrication, manual application and folding of the filter cloth are required, which results in high labor costs and low work efficiency. Utility Model Content

[0005] To address the above problems, this utility model provides a folding unit that can replace manual folding of filter cloth.

[0006] The folding unit provided by this utility model includes a main support, a sliding device, a rotating roller, and a synchronous walking platform. The sliding device is slidably mounted on the main support, and the central axis of the rotating roller is fixed to the sliding device. The filter cloth overlaps the surface of the rotating roller, and is output from the output side of the rotating roller as the sliding device reciprocates, forming a filter cloth block. The synchronous walking platform is located upstream of the rotating roller, and the filter cloth is conveyed on the synchronous walking platform along the conveying direction. The synchronous walking platform has a fixed section and a telescopic section, the telescopic section extending / retracting along the conveying direction.

[0007] According to the technical solution of this utility model, the filter cloth wrapped with material is first supported by the fixed section of the synchronous walking platform, and then conveyed to the rotating roller shaft by the extension and retraction of the telescopic section. The rotating roller shaft moves back and forth along the main support in the conveying direction under the drive of the sliding device, thereby continuously conveying the filter cloth and repeatedly folding it to form a filter cloth block. The folding of material is completed by mechanical equipment, which is more suitable for solid materials, reduces labor costs, and improves the working efficiency of the cloth in the pressing process of solid materials.

[0008] Furthermore, the synchronous walking platform ensures that the filter cloth is always conveyed to the corresponding position on the rotating roller shaft, regardless of how the sliding device moves, thus guaranteeing the flatness of the filter cloth throughout the conveying process. This significantly improves the regularity of the folded filter cloth block and increases the juice extraction rate of solid materials.

[0009] As an optional technical solution, the telescopic section of the synchronous walking platform extends and retracts synchronously with the movement of the sliding device, so that the end of the telescopic section is directly above the rotating roller.

[0010] According to this optional technical solution, the synchronous walking platform can continuously support the filter cloth, keeping it flat until the filter cloth is directly above the rotating roller shaft. The filter cloth can then fall directly onto the surface of the rotating roller shaft and be supported by it, thereby maximizing the flatness of the filter cloth before folding.

[0011] As an optional technical solution, the fixed section of the synchronous walking platform is fitted outside the telescopic section, and multiple protruding walking wheels are formed on the outer surface of the telescopic section.

[0012] According to this optional technical solution, the telescopic section can extend and retract along the length direction of the fixed section (i.e. the conveying direction of the filter cloth). When the telescopic section extends and retracts, the outer surface of the telescopic section does not move directly with the inner surface of the fixed section through sliding friction, but rather moves by rolling on the inner surface of the fixed section through the traveling wheels, making the movement of the telescopic section of the synchronous traveling platform smoother.

[0013] As an optional technical solution, the folding unit also includes a pressing device, with multiple pressing devices hinged to both sides of the sliding device for downward rotation to press the filter cloth.

[0014] According to the optional technical solution, by rotating multiple pressing devices, the freshly folded filter cloth can be pressed firmly onto the filter cloth support plate or filter cloth block, keeping the folded filter cloth block flat and facilitating uniform force distribution during subsequent pressing. Furthermore, by hinged multiple pressing devices to both sides of the sliding device, the filter cloth can be pressed by rotating the corresponding pressing device regardless of whether the folding unit is in the conveying direction or in the opposite direction.

[0015] As an optional technical solution, the clamping device includes a rotating arm and a rotating arm drive device. The rotating arm is hinged to the side of the sliding device, and the rotating arm drive device is used to drive the rotating arm to rotate.

[0016] According to the optional technical solution, the filter cloth is pressed down by simply rotating the end of the drive rotating arm. The structure is simple, the control is convenient, and it will not interfere with the output of the filter cloth, so that the filter cloth can be output and folded smoothly and evenly.

[0017] As an optional technical solution, the end of the rotating arm is bent to form a pressing end, and when the rotating arm rotates to a vertically downward position, the lower surface of the pressing end is horizontal.

[0018] According to the optional technical solution, when the rotating arm rotates to the vertically downward position, the lower surface of the pressing end can press the filter cloth to a horizontal position, further ensuring the flatness of the filter cloth block.

[0019] As an optional technical solution, the folding unit also includes fixing blocks fixed to both sides of the filter cloth block, and a telescopically arranged insertion rod between the two fixing blocks. When the insertion rod is extended, the filter cloth is clamped between the fixing blocks and the insertion rod.

[0020] According to this optional technical solution, by setting the fixing block and the insertion rod, it can be ensured that the folded ends of the filter cloth are consistent each time, so that the filter cloth block after final folding forms a regular cuboid, which is more conducive to subsequent pressing.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In this invention, "above" and "below" refer to the vertical arrangement relative to the direction of gravity, but do not directly limit the arrangement of two features in a vertically cumulative manner. The "above" or "below" of the first feature to 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," "on top of," and "over" the first feature to 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. "Below," "below," and "under" the first feature to the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] First Embodiment

[0038] Figure 1 This is a schematic diagram of the overall structure of the automated fabric distribution system provided in the first embodiment of this utility model. Figure 1 As shown, the automated fabric feeding system provided in this embodiment includes a filter cloth driving unit 1, a three-fold unit 2, a discharge unit 3, and a folding unit 4.

[0039] The filter cloth driving unit 1 can be any device capable of driving the filter cloth to be conveyed along the conveying direction. For example, it can be one or more rotating shafts linked to a motor, with the motor driving the rotating shafts to rotate. The filter cloth can be attached to the surface of the rotating shaft, or it can pass through the gap between two rotating shafts to drive the filter cloth to be conveyed by friction. The filter cloth driving unit 1 can be set at any position in the system, or it can include one or more filter cloth driving mechanisms at different positions to drive the filter cloth to be continuously conveyed along the conveying direction at any position in the overall process.

[0040] Before the filter cloth is fed into the three-fold unit 2, the filter cloth remains in an unfolded state. The discharge port 32 of the discharge unit 3 is set towards the unfolded filter cloth (i.e., the filter cloth at the entrance of the three-fold unit 2). The entrance of the three-fold unit 2 here does not refer to a specific dividing position. Any position where the filter cloth is unfolded and conveyed to the three-fold unit 2 can be regarded as the entrance position of the three-fold unit 2. The discharge unit 3 continuously conveys material to the unfolded filter cloth, so that as the filter cloth moves at a uniform speed, the material can be evenly spread in the center of the unfolded filter cloth.

[0041] The three-fold unit 2 is used to fold the two long sides of the filter cloth inward. Its structure is not limited here. It should be noted that the long sides of the filter cloth refer to the two edges of the filter cloth that are parallel to the conveying direction. That is, the three-fold unit 2 supports the long sides of the filter cloth and folds it towards the side of the filter cloth where the material is placed until it completely covers and wraps the material, and finally obtains a long strip of filter cloth wrapped with the material.

[0042] The folding unit 4 is located downstream of the three-fold unit 2. The specific structure of the folding unit 4 is not limited here. Those skilled in the art will understand that any structure capable of reciprocating in the conveying direction and capable of receiving the filter cloth can be used for this automated fabric feeding system. The filter cloth containing material conveyed by the three-fold unit 2 is received by the folding unit 4. As the folding unit 4 reciprocates, the continuously conveyed filter cloth is repeatedly folded to form filter cloth blocks. The folded filter cloth blocks can be received by containers such as filter cloth frames and filter cloth plates before being sent into the pressing system for pressing.

[0043] In this embodiment, mechanical equipment is used to lay and fold the material, which is more suitable for solid materials. It can significantly improve the juice extraction rate of solid materials, reduce labor costs, and improve the efficiency of material laying during the pressing process of solid materials (e.g., vinegar residue, distiller's grains).

[0044] The following, in conjunction with the accompanying drawings, further illustrates in detail the specific structure of the four units (filter cloth driving unit 1, three-fold unit 2, discharge unit 3, and folding unit 4) of the automated fabric feeding system in this embodiment.

[0045] [Discharge Unit 3]

[0046] The discharge unit 3 may include a storage device 31 and a discharge port 32. The storage device 31 contains solid materials. The outlet at the bottom of the storage device 31 is connected to the discharge port 32, and the discharge port 32 is located below the storage device 31. Thus, as long as the outlet of the storage device 31 is opened, the material can fall naturally to the discharge port 32 under the action of gravity, without the need for manual material spreading.

[0047] Furthermore, in some optional embodiments, a spreading machine 33 that conveys along the conveying direction can be provided between the outlet of the storage device 31 and the discharge port 32. The material output from the outlet of the storage device 31 is first evenly spread by the spreading machine 33, and then falls into the discharge port 32 from the outlet of the spreading machine 33. This makes the material entering the discharge port 32 more uniform and prevents the material from accumulating and affecting the flatness of the filter cloth.

[0048] [Tri-fold Unit 2]

[0049] Figure 2 This is a schematic diagram illustrating the folding process of a three-fold unit 2 provided in this embodiment. (In conjunction with...) Figure 1 and Figure 2 The three-fold unit 2 can include a base plate 21 and folding wings 22, with the folding wings 22 extending from the long sides of the base plate 21. First, the unfolded filter cloth is conveyed to the inlet of the three-fold unit 2, with the middle portion of the material placed on the upper surface of the base plate 21 and the two long sides placed on the upper surface of the folding wings 22, the middle portion of the filter cloth adhering to the base plate 21 during conveying. In the conveying direction, the folding wings 22 gradually fold towards the base plate 21 from the unfolded position. That is... Figure 2 As shown, the folding wing 22 is in a fully deployed state ( Figure 2 (at the very top), gradually folding inwards ( Figure 2 (Central), the filter cloth on the last two folding wings 22 completely covers the packaged material ( Figure 2 At the bottom, a long strip of filter cloth is obtained to wrap the material. No manual operation is required, further saving labor costs and improving production efficiency.

[0050] [Folding Unit 4]

[0051] Figures 3-6 An example is shown illustrating the structure of the folding unit 4 in four different states. In the first example, combined with... Figures 3-6 The folding unit 4 may include a main support 41, a sliding device 42, and a rotating roller 43. The main support 41 is disposed on a fixed surface and has legs 411 and a frame 412. The legs 411 are supported on the fixed surface (e.g., the ground), and the frame 412 is formed above the legs 411. Optionally, the height of the frame 412 may be aligned with the filter cloth output position of the three-fold unit 2 to facilitate the subsequent sliding device 42 receiving the filter cloth conveyed by the three-fold unit 2.

[0052] The sliding device 42 is slidably mounted on the frame 412 of the main support 41. For example, the frame 412 may have a crossbar (not shown in the figure) extending along the conveying direction. The sliding device 42 is mounted on the crossbar via pulleys, so that the sliding device 42 can reciprocate between the first end and the second end of the crossbar along the conveying direction. Furthermore, crossbars are formed on both sides corresponding to the long side of the filter cloth, and the two sliding devices 42 are respectively fixed on the two crossbars. When viewed from the side of the automated fabric feeding system (i.e., the viewing direction facing the paper in the figure), the two sliding devices 42 overlap.

[0053] The central axis of the rotating roller shaft 43 is fixed to the sliding device 42. In the case of two sliding devices 42, the two ends of the central axis of the rotating roller shaft 43 are respectively vertically fixed to the two sliding devices 42, so that the filter cloth conveyed by the three-fold unit 2 can just overlap the surface of the rotating roller shaft 43, and as the sliding device 42 moves, the filter cloth is output from the output side of the rotating roller shaft 43 (the right side of the rotating roller shaft 43 in the figure).

[0054] The sliding device 42 is directly slidably installed on both sides of the main support 41, which is simple in structure and reliable in fixation, and can also reduce spatial interference between the sliding device 42 and the filter cloth block when it moves. The rotating roller 43 fixed to the sliding device 42 can allow the filter cloth to overlap, and through the rotation of the rotating roller 43, the filter cloth overlapping on the rotating roller 43 can move back and forth with the sliding device 42 and be continuously output, and can also keep the filter cloth flat during the folding process.

[0055] In the second example, the basic structure of the folding unit 4 is the same as that in the first example, and will not be described again here. The difference from the first example is that the folding unit 4 in the second example may also include a pressing device 44, and multiple pressing devices 44 are respectively hinged to both sides of the sliding device 42 (the left and right sides in the figure).

[0056] The pressing device 44 can be any structure capable of actively rotating downwards from a horizontal position. For the purpose of making the structure of the folding unit 4 simpler and more compact, the pressing device 44 can optionally be a rotating arm 441 and a rotating arm drive mechanism 442, such as... Figures 3-6 As shown, the rotating arm 441 is hinged to the surface of the sliding device 42, the rotating arm drive mechanism 442 is fixed to the sliding device 42, and the drive end of the rotating arm 441 is connected to the far end of the rotating arm 441. By extending and retracting the drive end, the far end of the rotating arm 441 can be driven to rotate around the hinge position.

[0057] By rotating multiple pressing devices 44, the freshly folded filter cloth can be pressed firmly onto the filter cloth support plate (not shown) or the filter cloth block, keeping the folded filter cloth block flat and facilitating uniform force distribution during subsequent pressing. Furthermore, by hinged to both sides of the sliding device 42, the filter cloth can be pressed by rotating the corresponding pressing device 44, regardless of whether the folding unit 4 is in the conveying direction or in the opposite direction.

[0058] In the third example, the basic structure of the folding unit 4 is the same as in the first example, and will not be described again here. Unlike the first example, the folding unit 4 in the third example may also include a clamping device 45, located on the output side of the rotating roller 43 (to the right of the rotating roller 43 in the figure), with the filter cloth passing through the center of the clamping device 45. The clamping device 45 can be any structure capable of holding the filter cloth on its surface to keep it flat. Through the clamping of the clamping device 45, the material in the filter cloth can be evenly distributed, maintaining the flatness of the filter cloth before folding, which is beneficial for subsequent pressing.

[0059] Furthermore, during the folding process, as the sliding device 42 moves and the pressing device 44 rotates and presses down, the angle of the filter cloth on the output side of the rotating roller 43 continuously changes (see...). Figures 3-6 Therefore, in order to ensure that the filter cloth can always pass through the clamping device 45 smoothly and evenly, the clamping end of the clamping device 45 also needs to move with the movement of the filter cloth.

[0060] like Figure 7 As shown, the clamping device 45 may further include a clamping wheel 451 and an arc-shaped groove 453. The arc-shaped groove 453 is disposed on the sliding device 42, and the end of the clamping wheel 451 is formed as a snap-fit ​​shaft 452, which snaps into the arc-shaped groove 453. In the case of two sliding devices 42, two arc-shaped grooves 453 may also be formed, respectively arranged on both sides of the long side of the filter cloth. Both ends of the clamping wheel 451 are formed with snap-fit ​​shafts 452, which snap into the arc-shaped grooves 453 on both sides, further improving the structural stability of the clamping device 45.

[0061] Through the cooperation of the arc-shaped groove 453 and the snap-fit ​​shaft 452, the clamping wheel 451 can slide in the arc-shaped groove 453 and swing around the snap-fit ​​shaft 452, thereby freely adjusting the angle to adapt to the angle change of the filter cloth.

[0062] In the fourth example, the basic structure of the folding unit 4 is the same as in the first example, and will not be described again here. The difference from the first example is that the folding unit 4 in the fourth example also includes a synchronous walking platform 46. For example... Figure 8As shown, the synchronous walking platform 46 has a fixed section 461 and a telescopic section 462. The fixed section 461 is correspondingly arranged to the outlet of the three-fold unit 2, and the telescopic section 462 extends / retracts along the conveying direction. Between the three-fold unit 2 and the sliding device 42, the extension and retraction of the telescopic section 462 of the synchronous walking platform 46 can convey the filter cloth to the position corresponding to the rotating roller shaft 43, maintaining support for the filter cloth and keeping it flat.

[0063] The connection structure between the telescopic section 462 and the fixed section 461 is not limited here. Those skilled in the art will understand that as long as the telescopic section 462 can extend / retract relative to the fixed section 461 in the conveying direction, it is applicable to this utility model. For example, in some embodiments, the telescopic section 462 can be sleeved with the fixed section 461 (the telescopic section 462 is sleeved on the outer surface of the fixed section 461, or the fixed section 461 is sleeved on the outer surface of the telescopic section 462). In other embodiments, the surface of the telescopic section 462 can be provided with guide ribs along the conveying direction, and the surface of the fixed section 461 is correspondingly provided with guide grooves. The telescopic connection is achieved through the snap-fit ​​cooperation of the guide ribs and the guide grooves. All of the above are within the protection scope of this utility model.

[0064] In some preferred embodiments, the fixed segment 461 is sleeved on the outside of the telescopic segment 462, and a plurality of protruding traveling wheels 463 are formed on the outer surface of the telescopic segment 462. Thus, when the telescopic segment 462 extends or retracts, the outer surface of the telescopic segment 462 does not move directly against the inner surface of the fixed segment 461 through sliding friction, but rather rolls on the inner surface of the fixed segment 461 through the traveling wheels 463, making the movement of the telescopic segment 462 of the synchronous walking platform 46 smoother.

[0065] Furthermore, the telescopic section 462 of the synchronous walking platform 46 can extend and retract synchronously with the movement of the sliding device 42. The upper plane of the synchronous walking platform 46 is flush with the tangent point on the rotating roller shaft 43, meaning that the end of the telescopic section 462 can always remain aligned with the rotating roller shaft 43. Thus, before the filter cloth wrapped with material is conveyed from the three-fold unit 2 to the folding unit 4, the synchronous walking platform 46 can support the filter cloth, preventing it from falling directly. Moreover, by extending and retracting the telescopic section 462 of the synchronous walking platform 46 synchronously with the reciprocating movement of the folding unit 4, the filter cloth wrapped with material can be smoothly moved from the synchronous walking platform 46 to the folding unit 4, maintaining a uniform material shape.

[0066] In this embodiment, such as Figure 3 As shown, at this time, the sliding device 42 is at the first end (left end in the figure), the filter cloth overlaps the rotating roller shaft 43, and passes obliquely to the right through the clamping device 45 from the output side of the rotating roller shaft 43, maintaining tension. Then, the rotating arm drive mechanism 442 on the right side of the sliding device 42 drives the distal end of the rotating arm 441 to rotate downwards and press. Figure 4As shown, the clamping wheel 451 of the clamping device 45 swings to a vertically downward position within the arc-shaped slide groove 453, flattening the inclined filter cloth onto the lower plane. Then, the insert rod 6 presses the filter cloth against the fixing block 5 on the left side, preventing the already pressed filter cloth from being dragged during the subsequent back-and-forth movement of the sliding device 42. Next, the sliding device 42 is driven to move from the first end to the second end.

[0067] like Figure 5 As shown, at this time, the sliding device 42 is at the second end (right end in the figure), the filter cloth overlaps the rotating roller shaft 43, and passes obliquely to the left through the clamping device 45 from the output side of the rotating roller shaft 43, maintaining tension. Then, the rotating arm drive mechanism 442 on the left side of the sliding device 42 drives the distal end of the rotating arm 441 to rotate downward and press. Figure 6 As shown, the clamping wheel 451 of the clamping device 45 swings to a vertically downward position within the arc-shaped slide groove 453, flattening the inclined filter cloth onto the lower plane. Then, the insert rod 6 presses the filter cloth against the fixing block 5 on the right side, preventing the already pressed filter cloth from being dragged during the subsequent back-and-forth movement of the sliding device 42. Next, the sliding device 42 is driven to move from the second end to the first end.

[0068] [Filter Cloth Drive Unit 1]

[0069] The filter cloth drive unit 1 can be positioned at any location in the automated fabric feeding system to drive the fabric to be conveyed along the conveying direction. Optionally, the filter cloth drive unit 1 may include a first filter cloth drive mechanism 11 and a second filter cloth drive mechanism 12. The first filter cloth drive mechanism 11 is fixed to the upstream side of the three-fold unit 2, and its structure is not limited. The second filter cloth drive mechanism 12 is fixed to the outlet of the three-fold unit 2, and includes multiple drive rollers (not shown in the figure) that are vertically opposite each other and spaced apart. The filter cloth passes through the gaps between the drive rollers under their drive.

[0070] In this embodiment, the first filter cloth driving mechanism 11 can convey the unfolded filter cloth to the three-fold unit 2 so that the subsequent discharge unit 3 can evenly distribute the material. The second filter cloth driving mechanism 12 drives the three-folded filter cloth to continue to be conveyed to the folding unit 4. It is worth mentioning that the second filter cloth driving mechanism 12 conveys the filter cloth through the gap in the middle of the driving roller shaft, which can further evenly compact the material in the filter cloth while conveying the filter cloth, so as to keep the filter cloth shape flat.

[0071] In other embodiments of this utility model, such as Figure 9 As shown, the automated fabric application system may also include fixing blocks 5 fixed to both sides of the filter cloth block, and insert rods 6 telescopically disposed between the two fixing blocks 5. When the insert rods 6 are extended, the filter cloth is clamped between the fixing blocks 5 and the insert rods 6.

[0072] Specifically, such as Figure 4 As shown, when the sliding device 42 is at the first end and the inclined filter cloth is flatly pressed onto the lower plane, the insertion rod 6 at the first end extends, and the insertion rod 6 at the second end retracts, allowing the filter cloth at the first end to be fixed between the insertion rod 6 at the first end and the fixing block 5. At this time, the sliding device 42 moves from the first end to the second end, and the filter cloth at the first end remains fixed, thereby causing the filter cloth to be inclinedly stretched between the rotating roller shaft 43 and the insertion rod 6. Similarly, as... Figure 6 As shown, when the sliding device 42 is at the second end and the inclined filter cloth is pressed against the lower plane, the insertion rod 6 at the first end retracts, the insertion rod 6 at the second end extends, and the filter cloth at the second end is fixed between the insertion rod 6 at the second end and the fixing block 5.

[0073] By setting the fixing block 5 and the insertion rod 6, it can be ensured that the folded ends of the filter cloth are consistent each time, and the folded filter cloth will not be displaced as the folding unit 4 moves, so that the finally folded filter cloth block forms a regular cuboid, which is more conducive to subsequent pressing.

[0074] In this embodiment, by setting up the filter cloth driving unit 1, the discharge unit 3, the three-fold unit 2 and the folding unit 4, the entire process of solid material feeding and filter cloth folding can be automated, minimizing labor costs and producing more regular filter cloth blocks, which is beneficial for subsequent pressing.

[0075] Second Embodiment

[0076] Figure 10 This is a flowchart of an automated fabric distribution method provided in the second embodiment of the present invention. This automated fabric distribution method can be applied to any automated fabric distribution system in the first embodiment, but is not limited thereto. Any automated fabric distribution system having a filter cloth driving unit 1 and a folding unit 4, even without the three-fold unit 2, discharge unit 3, and other structures in the above-mentioned automated fabric distribution system, is also applicable to the automated fabric distribution method provided in this embodiment.

[0077] Combination Figure 1 and Figure 10 The automated fabric distribution method provided in the second embodiment of this utility model includes at least the following steps:

[0078] In conveying step S1, the filter cloth driving unit 1 continuously conveys the filter cloth along the conveying direction;

[0079] In the discharge step S2, material is conveyed onto the unfolded filter cloth;

[0080] In wrapping step S3, after the discharge step, the long sides of the unfolded filter cloth are folded inward to wrap the material.

[0081] In step S4, the folding unit 4 is driven to move to receive the filter cloth output from the wrapping step, and then the folding unit 4 is driven to reciprocate in the conveying direction to repeatedly fold the filter cloth to form a filter cloth block.

[0082] It should be noted that the step numbers S1, S2, S3, S11, etc., are only for ease of explanation and do not limit the order in which the steps are executed. For example, the conveying step S1 can be executed before or after any step, simultaneously with any step, or continuously throughout the automated material feeding process, all of which fall within the protection scope of this utility model.

[0083] In some optional embodiments, the conveying step S1 may include the following sub-steps:

[0084] In the first conveying step S11, before the discharge step S2, the first filter cloth driving mechanism 11 continuously conveys the unfolded filter cloth along the conveying direction.

[0085] In the second conveying step S12, after the wrapping step S3, the second filter cloth driving mechanism 12 drives the filter cloth through the gap in the middle of the second filter cloth driving mechanism 12 and conveys the filter cloth to the folding unit 4 along the conveying direction.

[0086] In some alternative embodiments, the automated fabric application method may further include:

[0087] In the synchronous fabric supply step S5, after the wrapping step, the filter cloth is conveyed synchronously with the movement of the folding unit 4 to transport the filter cloth to the folding unit 4. The synchronous fabric supply step S5 is performed via the synchronous walking platform 46. After the material is wrapped, the filter cloth is first supported by the fixed section 461 of the synchronous walking platform 46, and then conveyed to the folding unit 4 by the extension and retraction of the telescopic section 462. Thus, the telescopic section 462 can continuously support the filter cloth before folding, keeping the filter cloth flat. To further ensure the flat transport of the filter cloth, in the synchronous fabric supply step S5, the telescopic section 462 extends and retracts synchronously with the movement of the folding unit 4 to transport the filter cloth directly above the folding unit 4. The filter cloth can then move smoothly to the folding unit 4, achieving direct docking between the filter cloth and the synchronous walking platform 46 and the folding unit 4.

[0088] Specifically, firstly, the first filter cloth driving mechanism 11 performs the first conveying step S11, continuously conveying the unfolded filter cloth to the three-fold unit 2.

[0089] Then, the discharge unit 3 performs the discharge step S2, spreading material from the discharge port 32 to the center of the continuously conveyed unfolded filter cloth. As the filter cloth moves, the material is evenly spread on the filter cloth.

[0090] Then, the three-fold unit 2 performs the wrapping step S3, flipping and folding the long side of the filter cloth to form a long strip of filter cloth wrapped with material.

[0091] Subsequently, the second filter cloth driving mechanism 12 performs the second conveying step S12, and the filter cloth output by the three-fold unit 2 passes through the gap in the middle of the second filter cloth driving mechanism 12 and continues to be conveyed to the folding unit 4 along the conveying direction.

[0092] Then, the synchronous walking platform 46 performs the synchronous fabric feeding step S5, and moves synchronously with the folding unit 4 via the telescopic section 462 to transport the filter cloth directly above the rotating roller 43 of the folding unit 4.

[0093] Finally, the folding unit 4 performs the folding step S4. After the long strip of filter cloth wrapped in the wrapping step S3 enters the folding unit 4, the folding unit 4 moves back and forth in the conveying direction, so that the continuously conveyed filter cloth is repeatedly folded under the drive of the folding unit 4 to form a filter cloth block.

[0094] In this embodiment, a control method for a fully automatic material spreading system is provided, which can complete the entire process of material laying and folding with the assistance of mechanical equipment. It is more suitable for solid materials, can significantly improve the juice extraction rate of solid materials, reduce labor costs, and improve the efficiency of material spreading during the pressing process of solid materials.

[0095] Figure 11 This is a flowchart of a folding step provided in the second embodiment of this utility model. (In conjunction with...) Figure 3-6 From point 11, the folding step S4 can include the following sub-steps:

[0096] In the moving step S41, the folding unit 4 is driven to move from the first end to the second end, or the folding unit 4 is driven to move from the second end to the first end.

[0097] In the pressing step S42, after the moving step S41, the filter cloth is pressed down and folded. Optionally, in the pressing step S42, the end of the pressing device 44 is driven to rotate to fold and press the filter cloth.

[0098] The moving step S41 and the pressing step S42 are performed in a loop. Figure 10 (Not shown in the figure) This allows the freshly folded filter cloth to be pressed firmly onto the filter cloth support plate (not shown) or the filter cloth block, keeping the folded filter cloth block flat and making it easier for the filter cloth block to be evenly stressed during subsequent pressing.

[0099] Optionally, the folding step S4 may further include a clamping step S43, performed simultaneously with the moving step S41 and the pressing step S42, clamping the filter cloth during the folding process and allowing it to pass through. Taking the automated fabric system in the first embodiment as an example, in the clamping step S43, the clamping wheel 451 clamps the continuously output filter cloth, and as the filter cloth moves, the clamping wheel 451 swings along the arc-shaped groove 453.

[0100] By simultaneously performing the clamping step S43 during the moving step S41 and the pressing step S42, the filter cloth must pass through the clamping device 45 before being pressed. This ensures that the material is evenly distributed during the folding process of the filter cloth, resulting in a flat filter cloth shape that is beneficial for subsequent pressing.

[0101] Further optionally, the folding step S4 may also include a filter cloth fixing step S44, in which the pressed filter cloth is fixed at the first end / second end after the pressing step S42. Taking the automated cloth feeding system in the first embodiment as an example, in the filter cloth fixing step S44, after the filter cloth is fixed and pressed at the first end / second end, the corresponding insertion rod 6 at the first end / second end extends and cooperates with the fixing block 5 to clamp the filter cloth.

[0102] After the pressing step S42 and before the next moving step S41, the filter cloth fixing step S44 is performed. By controlling the fixing block 5 and the insertion rod 6, it can be ensured that the folded ends of the filter cloth are consistent each time, and the filter cloth at the folded end will not be displaced as the folding unit 4 moves. This ensures that the filter cloth is kept pressed in the filter cloth block and will not become uneven such as curling edges as the folding unit 4 moves.

[0103] Specifically, such as Figure 3 As shown, at this time, the sliding device 42 is at the first end (left end in the figure), the filter cloth overlaps the rotating roller shaft 43, and passes obliquely to the right through the clamping device 45 from the output side of the rotating roller shaft 43, maintaining tension. Then, the pressing step S42 is executed, and the rotating arm drive mechanism 442 of the pressing device 44 on the right side of the sliding device 42 drives the distal end of the rotating arm 441 to rotate downward to press the filter cloth. Figure 4 As shown, clamping step S43 is executed simultaneously. The clamping wheel 451 of the clamping device 45 swings to a vertically downward position within the arc-shaped slide groove 453, and the inclined filter cloth is flatly pressed onto the lower plane. Then, filter cloth fixing step S44 is executed. The insertion rod 6 at the first end extends, and the insertion rod 6 at the second end retracts, fixing the pressed filter cloth at the first end. Afterward, moving step S41 is executed, and clamping step S43 is executed simultaneously, driving the sliding device 42 to move from the first end to the second end, and the filter cloth is inclined and tightened.

[0104] like Figure 5 As shown, at this time, the sliding device 42 is at the second end (right end in the figure), the filter cloth overlaps the rotating roller shaft 43, and passes obliquely to the left through the clamping device 45 from the output side of the rotating roller shaft 43, maintaining tension. Then, the pressing step S42 is executed, and the rotating arm drive mechanism 442 of the pressing device 44 on the left side of the sliding device 42 drives the distal end of the rotating arm 441 to rotate downward to press the filter cloth. Figure 6As shown, clamping step S43 is performed simultaneously. The clamping wheel 451 of the clamping device 45 swings to a vertically downward position in the arc-shaped slide groove 453. The inclined filter cloth is flatly pressed onto the lower plane. Then, filter cloth fixing step S44 is performed. The insertion rod 6 at the first end retracts and the insertion rod 6 at the second end extends. The pressed filter cloth is fixed at the second end. After that, moving step S41 is performed, and clamping step S43 is performed simultaneously. The sliding device 42 is driven to move from the second end to the first end.

[0105] In this embodiment, an automated material distribution method is provided that can be applied to an automated material distribution system for solid materials. By controlling the fully automated equipment, no manual labor is required, which can greatly save costs and improve work efficiency.

[0106] The above are merely preferred embodiments of the present utility model and are 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.
