Technical Field

[0001] This application relates to the field of pressing equipment technology, and in particular to a stacking device and a pressing production line. Background Technology

[0002] A pressing production line is a device for separating solids and liquids, mainly used in industries such as soy sauce brewing, winemaking, sugar refining, and chemicals. The production steps of a pressing production line typically include: stacking filter cloths while filling them with material; transferring the stacked filter cloths to a pressing device for pressing the filter cloths and the material they contain; collecting the pressed liquid; and separating the pressed residue from the filter cloths. However, during the stacking process, some liquid from the material encased in the filter cloths leaks out, requiring collection and processing, making the operation cumbersome and resulting in low pressing efficiency.

[0014] In one embodiment, for each of the synchronous pulleys located on any side of the filter cloth, the number of synchronous pulleys of each synchronous pulley is the same and their positions are arranged one-to-one along the axial direction of the synchronous pulleys. The first traction mechanism further includes a plurality of first connecting shafts. The plurality of synchronous pulleys corresponding to the positions along the axial direction of the synchronous pulleys are set as a group. Each group is arranged corresponding to each of the first connecting shafts, and all the synchronous pulleys of each group are coaxially mounted on the corresponding first connecting shaft.

[0018] A distance adjustment mechanism is provided, which is connected to at least one of the traction roller and the second connecting shaft. The distance adjustment mechanism can adjust the distance between the second connecting shaft and the traction roller, so that the clamping wheel cooperates with the traction roller to clamp or release the filter cloth.

[0019] A drive mechanism is provided, which is connected to at least one of the traction roller and the second connecting shaft, and is used to drive the traction roller and the second connecting shaft to rotate.

[0020] In one embodiment, the stacking device further includes a lifting mechanism and a material support plate; the bottom of the pressing cage is provided with an opening, the lifting part of the lifting mechanism can enter and exit the opening, and is used to drive the material support plate to move up and down; the material support plate is movably disposed inside the pressing cage to receive the stacked filter cloth and drive the filter cloth to descend or drive the filter cloth to rise after pressing.

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] See Figure 1 and Figure 2 , Figure 1 A structural view of a pressing production line according to an embodiment of this application is shown. Figure 2 It shows Figure 1 The diagram shows another structural view of the pressing production line. One embodiment of this application provides a stacking device 10, including: a pressing cage 11, a telescopic mechanism 12, and a first traction mechanism 13. The telescopic mechanism 12 is mounted on a frame 20 and located on one side of the pressing cage 11. The first traction mechanism 13 is used to pull the filter cloth 30 to move. The telescopic mechanism 12 is connected to the first traction mechanism 13, and the telescopic mechanism 12 drives the first traction mechanism 13 to reciprocate between an initial position and a feeding position, causing the filter cloth 30 to reciprocate and stack inside the pressing cage 11, with the direction of movement as shown in the diagram. Figure 1 As shown by the double arrow x in the diagram. When the first traction mechanism 13 is in the initial position, the first traction mechanism 13 is completely misaligned with the pressing cage 11 in the vertical direction; when the first traction mechanism 13 is in the feeding position, the first traction mechanism 13 is directly above the pressing cage 11.

[0044] The first traction mechanism 13 is completely offset from the pressing cage 11 in the vertical direction, meaning that the first traction mechanism 13 is not located directly above the pressing cage 11. In this way, the first traction mechanism 13 will not interfere with the operation of the press, and the press can enter the interior of the pressing cage 11 from the top and press the filter cloth 30 stacked inside the pressing cage 11.

[0045] The first traction mechanism 13 is located directly above the pressing cage 11, meaning that the first traction mechanism 13 overlaps with the pressing cage 11 in the vertical direction. In this way, the first traction mechanism 13 can pull the filter cloth 30 and allow the filter cloth 30 to be fed into the interior of the pressing cage 11.

[0046] Specifically, when stacking the filter cloth 30, the first traction mechanism 13 pulls the filter cloth 30 so that the filter cloth 30 moves toward the pressing cage 11. At the same time, the telescopic mechanism 12 drives the first traction mechanism 13 to reciprocate between the initial position and the traction position, thereby realizing the reciprocating stacking of the filter cloth 30 into the interior of the pressing cage 11.

[0047] To facilitate the reciprocating stacking of the filter cloth 30 into the pressing cage 11, the speed at which the first traction mechanism 13 moves the filter cloth 30 toward the pressing cage 11 is defined as V1, and the extension speed of the telescopic mechanism 12 is defined as V2. Optionally, V1 / V2 may be set to 1 to 1.2, specifically, for example, 1, 1.05, 1.1, 1.15, or 1.2, etc.

[0048] It should be noted that in this embodiment, the pressing cage 11 can be connected to the frame 20 or not connected to it, depending on the actual needs.

[0049] The aforementioned stacking device 10, telescopic mechanism 12, and first traction mechanism 13 work together to pull the filter cloth 30, causing it to be stacked in a Z-shape back and forth into the pressing cage 11. Thus, on the one hand, the filter cloth 30 completes the stacking operation inside the pressing cage 11, and the liquid generated during the stacking process can be directly collected by the liquid receiving tray below the pressing cage 11, facilitating the centralized collection and treatment of liquid flowing outwards during the stacking process; on the other hand, since the stacked filter cloth 30 is inside the pressing cage 11, and the first traction mechanism 13 is located outside the pressing cage 11 and will not interfere with the press, subsequent pressing operations can be carried out directly through the press, thus omitting the step of transferring the stacked filter cloth 30 into the pressing cage 11 in related technologies, thereby improving pressing efficiency.

[0050] The telescopic mechanism 12 in this embodiment has many specific structural forms, including but not limited to a motor gear rack structure, a motor lead screw, a cylinder or a hydraulic cylinder, etc., as long as it can drive the first traction mechanism 13 to reciprocate between the initial position and the feeding position, it is not limited here.

[0051] As an example, the telescopic mechanism 12 includes a first motor, a transmission gear, and a transmission rack. The first motor is mounted on the frame 20, the transmission gear is connected to the shaft of the first motor, and the transmission gear also meshes with the transmission rack. The transmission rack is movably mounted on the frame 20 and is connected to the first traction mechanism 13. When the first motor rotates forward or reverse, it can drive the transmission rack to move, and the transmission rack correspondingly drives the first traction mechanism 13 to extend or retract.

[0052] In one embodiment, the connection between the telescopic mechanism 12 and the first traction mechanism 13 can be either direct or indirect, as long as it can drive the first traction mechanism 13 to retract and extend as a whole. In this embodiment, the stacking device 10 also includes a support. The first traction mechanism 13 is mounted on the support, and the telescopic mechanism 12 is connected to the support. The telescopic mechanism 12 drives the support to move, thereby driving the first traction mechanism 13 to reciprocate and extend and extend.

[0053] To prevent material leakage from the opposite sides of the filter cloth 30 during the pressing process, in this embodiment, the filter cloth 30 is folded at least twice along its width. This ensures that the filter cloth 30 completely covers the internal material, preventing leakage from the opposite sides and effectively solving the leakage problem. For details, please refer to... Figures 3 to 5 , Figure 3 The diagram illustrates the filter cloth 30 divided into three equal parts along its width and in an unfolded state. The three equal parts correspond to three unit layers 31, and the width of the unit layers is the same or they are allowed to have a process deviation of less than 10%. Figure 4 This diagram illustrates the structure of three unit layers 31 folded together to enclose the material. Figure 4 As can be seen, the material is wrapped on both sides by filter cloth 30, thus preventing material leakage. Figure 5 This diagram illustrates the state in which the filter cloth 30 is folded by the folding mechanism 50 of this application in a manner similar to turning up a collar. Figure 5 From left to right, the filter cloth 30 gradually changes from one layer to three layers. Simultaneously, before the filter cloth 30 is folded, material can be fed into the middle portion of the filter cloth 30 via the feeder 90, specifically onto the unit layer 31 in the middle position of the filter cloth 30. The closer the feeding position is to the folding position of the filter cloth 30, the better it will prevent material from flowing outwards. In this embodiment, the feeding position is selected as follows... Figure 5 The left side of the unit layer 31 in the middle position is shown. In this way, after the material is put into the left side of the unit layer 31 in the middle position, it can be wrapped by the other two unit layers 31 of the filter cloth 30, thereby achieving a good wrapping effect and effectively preventing the material from flowing out.

[0054] Because the material is wrapped in the filter cloth 30, the weight of the filter cloth 30 will increase, and the material inside the filter cloth 30 will be difficult for the first traction mechanism 13 to clamp, thus affecting the traction effect of the first traction mechanism 13 on the filter cloth 30. Specifically, during the process of pulling the filter cloth 30 from the initial position to the feeding position, if the clamping force of the first traction mechanism 13 on the filter cloth 30 is too large, the material will easily leak out; conversely, if the clamping force of the first traction mechanism 13 on the filter cloth 30 is too small, it will be unable to move the filter cloth 30 from the initial position to the feeding position.

[0055] Based on this, in order to ensure the traction effect of the filter cloth 30 containing the material moving towards the pressing cage 11, this embodiment provides some technical solutions for the first traction mechanism 13, which can ensure a good traction effect of the filter cloth 30. The first traction mechanism 13 will be described in detail below.

[0056] Please see Figure 1 , Figures 6 to 8 In one embodiment, the first traction mechanism 13 includes a traction unit 131, a distance adjustment mechanism 132, and a drive mechanism 133. The traction unit 131 includes two synchronous pulleys 134, located on opposite upper and lower sides of the filter cloth 30. Each synchronous pulley 134 includes at least two synchronous wheels 1341 and a synchronous belt 1342 surrounding the at least two synchronous wheels 1341. The synchronous belt 1342 is used to contact the filter cloth 30. The two synchronous pulleys 1341 of the two synchronous pulleys 134 are of the same number and their positions correspond one-to-one. The distance adjustment mechanism 132 is connected to at least one synchronous pulley 134 in the traction unit 131. The distance adjustment mechanism 132 can adjust the distance between the two synchronous pulleys 134 in the traction unit 131, so that the two synchronous pulleys 134 clamp or release the filter cloth 30. The drive mechanism 133 is connected to at least one synchronous pulley 134 in the traction unit 131 and is used to drive the synchronous pulley 134 to rotate.

[0057] When the first traction mechanism 13 is in operation, if the filter cloth 30 needs to be tractioned, the distance adjustment mechanism 132 adjusts the distance between the two synchronous pulleys 134 so that the synchronous pulleys 134 clamp the filter cloth 30. Then, the drive mechanism 133 drives the synchronous pulleys 134 to rotate, thereby enabling the filter cloth 30 to move towards the pressing cage 11. Conversely, when the filter cloth 30 does not need to be tractioned, the distance adjustment mechanism 132 adjusts the distance between the two synchronous pulleys 134 so that the synchronous pulleys 134 release the filter cloth 30. The synchronous belts 1342 of the two synchronous pulleys 134 clamp the filter cloth 30 on the upper and lower opposite sides respectively. Driven by the drive mechanism 133, the friction between the two synchronous belts 1342 and the filter cloth 30 enables the filter cloth 30 to move towards the pressing cage 11. At the same time, the clamping force of the synchronous belts 1342 on the filter cloth 30 is relatively reduced, so the material wrapped inside the filter cloth 30 is less likely to leak out.

[0058] It should be noted that the number of synchronous pulleys 1341 in each synchronous pulley 134 is, but is not limited to, two (e.g., Figure 7 As shown), three, four (as shown) Figure 8 (As shown), six or more. When the number of synchronous pulleys 134 is greater, the length of the synchronous belt 1342 is correspondingly longer, and the contact area between the synchronous belt 1342 and the filter cloth 30 will be larger, thus increasing the frictional force between them and the filter cloth 30, thereby improving the traction force on the filter cloth 30. Conversely, when the number of synchronous pulleys 134 is less, the length of the synchronous belt 1342 is correspondingly smaller, and the traction force of the synchronous pulleys 134 on the filter cloth 30 decreases. The specific number of synchronous pulleys 134 can be flexibly adjusted and set according to the characteristics of the material wrapped by the filter cloth 30 and the single extension length of the telescopic mechanism 12, and is not specifically limited here.

[0059] Based on the aforementioned embodiment, the outer surface of the timing belt 1342 is provided with anti-slip texture. In this way, the anti-slip texture can increase the friction between the timing belt 1342 and the filter cloth 30, thereby ensuring the traction effect on the filter cloth 30 and preventing slippage during the traction process of the filter cloth 30.

[0060] The anti-slip texture can be in various forms such as patterns, designs, or raised dots, as long as it can increase the friction between the anti-slip texture and the filter cloth 30. The specific form is not limited here.

[0061] Please see Figure 1 , Figures 6 to 8Based on the aforementioned embodiments, there are at least two traction units 131, which are arranged sequentially at intervals along the width direction of the filter cloth 30. The position adjustment mechanism can synchronously adjust the distance between the two synchronous pulleys 134 of each traction unit 131, and the drive mechanism 133 can synchronously drive each traction unit 131. Thus, when tractioning the filter cloth 30, each traction unit 131 operates synchronously under the drive of the drive mechanism 133. The synchronous belts 1342 of each traction unit 131 synchronously contact the filter cloth 30 and pull the filter cloth 30 toward the pressing cage 11, resulting in a large traction force on the filter cloth 30 and a good traction effect. Moreover, since each traction unit 131 is arranged at intervals along the width direction of the filter cloth 30, after each traction unit 131 squeezes and clamps the filter cloth 30, the material wrapped in the filter cloth 30 can be squeezed into the area between two adjacent traction units 131. This ensures a large traction force while reducing the material being squeezed to the outside of the filter cloth 30, effectively solving the problem of the filter cloth 30 being difficult to clamp when wrapped with material. In addition, the position adjustment mechanism can synchronously adjust the distance between the two synchronous pulleys 134 of each traction unit 131, making the overall structure simple and the clamping force in each position consistent, thereby improving the traction effect of the filter cloth 30.

[0062] In some embodiments, similar to the telescopic mechanism 12, the distance adjustment mechanism 132 has various specific structural forms, including but not limited to a motor gear rack structure, a motor lead screw, a cylinder, or a hydraulic cylinder, etc. As long as it can drive any one of the synchronous pulleys 134 of the traction unit 131 to move up and down, thereby adjusting the distance between the two synchronous pulleys 134, the specific setting is not limited here. The adjustment range of the distance adjustment mechanism 132 on the synchronous pulleys 134 includes, but is not limited to, 5mm, 6mm, 8mm, 10mm, 12mm, or 15mm, etc. The specific size can be adjusted and set according to the specific thickness of the filter cloth 30, and is not limited here. When the distance adjustment mechanism 132 adjusts the synchronous pulleys 134 to a distance that reaches its preset lifting range, it can clamp the filter cloth 30 and achieve traction of the filter cloth 30; conversely, when the distance adjustment mechanism 132 adjusts the synchronous pulleys 134 to a distance that reaches its preset lifting range, it can release the filter cloth 30. Furthermore, the direction of the distance adjustment mechanism 132 adjusting the synchronous pulleys 134 is as follows: Figure 1 The double arrow z in the diagram is shown.

[0063] Please see Figures 6 to 8For example, for each synchronous pulley 134 located on any side of the filter cloth 30, the number of synchronous pulleys 1341 of each synchronous pulley 134 is the same and their positions are arranged one-to-one along the axial direction of the synchronous pulleys 1341. The first traction mechanism 13 also includes multiple first connecting shafts 135. Multiple synchronous pulleys 1341 corresponding to each other along the axial direction of the synchronous pulleys 1341 are set as a group, and each group is arranged corresponding to each first connecting shaft 135. All synchronous pulleys 1341 of each group are coaxially mounted on the corresponding first connecting shaft 135. At least one first connecting shaft 135 of the traction unit 131 is connected to the drive mechanism 133, which is used to drive the two synchronous pulleys 134 of the traction unit 131 to rotate in opposite directions. Thus, when the drive mechanism 133 is working, it can drive the first connecting shaft 135 to rotate. Under the transmission action of the synchronous belt 1342 and the first connecting shaft 135, all the synchronous pulleys 134 of the traction units 131 can simultaneously perform traction actions, thereby ensuring the traction effect of the filter cloth 30. In addition, it can simplify the overall structure of the first traction mechanism 13, thereby reducing costs.

[0064] Please see Figure 1 , Figure 9 and Figure 10 In another embodiment, the first traction mechanism 13 includes: a traction roller 136, a second connecting shaft 137, a plurality of clamping wheels 138, a distance adjustment mechanism 132, and a drive mechanism 133. The traction roller 136 contacts the lower side of the filter cloth 30. The plurality of clamping wheels 138 are sequentially spaced and coaxially arranged on the second connecting shaft 137, and each clamping wheel 138 contacts the upper side of the filter cloth 30. The distance adjustment mechanism 132 is connected to at least one of the traction roller 136 and the second connecting shaft 137, and the distance adjustment mechanism 132 can adjust the distance between the second connecting shaft 137 and the traction roller 136 so that the clamping wheels 138 cooperate with the traction roller 136 to clamp or release the filter cloth 30. The drive mechanism 133 is connected to at least one of the traction roller 136 and the second connecting shaft 137, and the drive mechanism 133 is used to drive the traction roller 136 and the second connecting shaft 137 to rotate.

[0065] When the first traction mechanism 13 is in operation, if the filter cloth 30 needs to be tractioned, the distance adjustment mechanism 132 adjusts to reduce the distance between the second connecting shaft 137 and the traction roller 136, so that multiple clamping wheels 138 cooperate with the traction roller 136 to clamp the filter cloth 30. Then the drive mechanism 133 makes the traction roller 136 and the second connecting shaft 137 rotate, thereby enabling the filter cloth 30 to move towards the pressing cage 11. Conversely, when the filter cloth 30 does not need to be tractioned, the distance adjustment mechanism 132 adjusts to increase the distance between the second connecting shaft 137 and the traction roller 136, and the filter cloth 30 can be released. The filter cloth 30 is clamped on the upper and lower opposite sides by a traction roller 136 and multiple clamping wheels 138 respectively. Driven by the drive mechanism 133, the filter cloth 30 can be pulled towards the pressing cage 11 by the friction between the traction roller 136 and multiple clamping wheels 138 and the filter cloth 30. At the same time, the material wrapped in the filter cloth 30 can be squeezed into the area between two adjacent clamping wheels 138, so that the material wrapped inside the filter cloth 30 is not easy to leak out.

[0066] It should be noted that the number of clamping wheels 138 may include, but is not limited to, two, three, four, six, or more. A greater number of clamping wheels 138 results in a larger contact area between the entire assembly of the clamping wheels 138 and the filter cloth 30, thereby increasing the friction and thus improving the traction force on the filter cloth 30. Conversely, a smaller number of clamping wheels 138 reduces the contact area between the entire assembly of the clamping wheels 138 and the filter cloth 30, thus reducing the traction force on the filter cloth 30. The specific number of clamping wheels 138 can be flexibly adjusted and set according to the characteristics of the material wrapped by the filter cloth 30 and the single extension length of the telescopic mechanism 12, and is not specifically limited here.

[0067] Optionally, the telescopic mechanism 12 is indirectly or directly connected to the distance adjustment mechanism 132 and / or the drive mechanism 133, which can be flexibly adjusted and set according to actual needs.

[0068] For example, the stacking device 10 also includes a lifting mechanism and a support plate. The bottom of the pressing cage 11 has an opening, through which the lifting part of the lifting mechanism can enter and exit, and is used to drive the lifting movement of the support plate. The support plate is movably disposed inside the pressing cage 11, used to receive the stacked filter cloths 30 and to lower or raise the pressed filter cloths 30. Thus, during the stacking of the filter cloths 30, the lifting mechanism can first raise the support plate to the top of the pressing cage 11; then, through the cooperation of the telescopic mechanism 12 and the traction mechanism, the filter cloths 30 are stacked onto the support plate; as the filter cloths 30 are stacked on the support plate, the lifting mechanism gradually lowers the height of the support plate until the filter cloths 30 fill the entire pressing cage 11. Therefore, the lifting action of the lifting mechanism facilitates the neat stacking of the filter cloths 30 on the support plate. In addition, after the filter cloth 30 inside the pressing cage 11 has completed the pressing operation, during the process of pulling the filter cloth 30 outward, the filter cloth 30 can be gradually lifted by the lifting mechanism, so as to better complete the reverse slag removal process of the filter cloth 30.

[0069] For example, the stacking device 10 also includes a support beam. The support beam is located at the bottom of the pressing cage 11, and supports the material support plate when it moves to the bottom of the pressing cage 11. With this configuration, when the lifting mechanism moves the material support plate to the bottom of the pressing cage 11, the filter cloths 30 inside the pressing cage 11 are stacked. During the pressing process of the filter cloths 30 inside the pressing cage 11 by the press, the support beam and material support plate provide support for the filter cloths 30, thus ensuring the smooth completion of the pressing operation. Furthermore, it prevents the force of the press from being transmitted to the lifting mechanism, thus preventing damage to the lifting mechanism.

[0070] Optionally, the support beam can be fixed to the press or to the frame 20. The specific design can be flexibly adjusted and set according to actual needs, and no limitation is made here.

[0071] Optionally, the lifting mechanism may include, but is not limited to, lifting cylinders, motor lead screws, etc.

[0072] Please see Figure 1 and Figure 2 In one embodiment, this application also provides a pressing production line, which includes the stacking device 10 of any of the above embodiments, and further includes a frame 20, a press, and a liquid receiving device. A telescopic mechanism 12 is mounted on the frame 20. The press is used to press the filter cloth 30 inside the pressing cage 11. The liquid receiving device is located below the pressing cage 11 and is used to collect the liquid generated by the pressing cage 11. Optionally, the liquid receiving device includes, but is not limited to, a liquid receiving tray.

[0073] In the aforementioned pressing production line, the telescopic mechanism 12 and the first traction mechanism 13 work together to pull the filter cloth 30, causing it to be stacked in a Z-shape back and forth inside the pressing cage 11. Thus, on the one hand, the filter cloth 30 completes the stacking operation inside the pressing cage 11, and the liquid generated during the stacking process can be directly collected by the liquid receiving tray below the pressing cage 11; on the other hand, since the stacked filter cloth 30 is inside the pressing cage 11, and the first traction mechanism 13 is located outside the pressing cage 11 and will not interfere with the press, subsequent pressing operations can be carried out directly through the press. This eliminates the step of transferring the stacked filter cloth 30 into the pressing cage 11 in related technologies, thereby improving pressing efficiency.

[0074] For example, the pressing production line also includes a second traction mechanism 40. The second traction mechanism 40 is mounted on the frame 20 and is used to pull the filter cloth 30 so that the pressed filter cloth 30 is removed from the pressing cage 11. Thus, not only can the first traction mechanism 13 pull the filter cloth 30, but the second traction mechanism 40 can also pull the filter cloth 30, thereby adjusting the tension of the filter cloth 30. Furthermore, when removing the pressed filter cloth 30 from the pressing cage 11, to prevent the material from being crushed when the first traction mechanism 13 clamps the filter cloth 30, the first traction mechanism 13 can release the filter cloth 30, and the second traction mechanism 40 can then pull the filter cloth 30.

[0075] For example, the pressing production line also includes a folding mechanism 50. The folding mechanism 50 is mounted on the frame 20 and is used to fold the filter cloth 30 moving toward the pressing cage 11 into at least two layers in the width direction, or to unfold the filter cloth 30 taken out from inside the pressing cage 11. Thus, on the one hand, during the stacking of the filter cloth 30, the filter cloth 30 is pulled and moves forward toward the pressing cage 11. When the undisturbed filter cloth 30 passes through the folding mechanism 50, it can be folded from a single layer into at least two layers, and material is applied simultaneously with the folding of the filter cloth 30. On the other hand, after the pressing operation of the filter cloth 30 is completed, during the process of pulling the filter cloth 30 out of the pressing cage 11 from the inside in the opposite direction, when the filter cloth 30 wrapped with residue passes through the folding mechanism 50 in the opposite direction, the folding mechanism 50 can unfold the filter cloth 30 and expose the wrapped residue.

[0076] Based on the foregoing embodiments, the pressing production line also includes a slag scraping mechanism 60, for example. The slag scraping mechanism 60 is disposed on the frame 20 and is used to scrape slag from the unfolded filter cloth 30.

[0077] Based on the foregoing embodiments, the pressing production line also includes a slag conveying device 70, for example. The slag conveying device 70 is located below the slag scraping mechanism 60 and is used to receive the slag scraped off by the slag scraping mechanism 60 and convey the slag to a collecting device.

[0078] To ensure that the filter cloth 30 is folded from a single layer into three layers via the folding mechanism 50, that is, as shown in the figure... Figure 3 The filter cloth shown is folded 30 times as follows Figure 4 As shown in the folded configuration, the tightness of the filter cloth 30 needs to be adjusted and controlled within a manageable range. Please refer to [link / reference needed]. Figure 1 and Figure 11 For example, the pressing production line also includes a tension adjustment mechanism 80. The tension adjustment mechanism 80 is mounted on the frame 20, located between the first traction mechanism 13 and the second traction mechanism 40. The tension adjustment mechanism 80 is used to adjust the tension of the filter cloth 30. Thus, the tension adjustment mechanism 80 ensures that the filter cloth 30 is taut at a suitable tension level, thereby improving the folding quality of the filter cloth 30.

[0079] Specifically, the tension adjustment mechanism 80 includes a fabric support frame 81, a guide roller 82, a counterweight 83, and a position sensor 84. The fabric support frame 81 is rotatably mounted on the frame 20. One end of the fabric support frame 81 is connected to the counterweight 83, and the other end is connected to the guide roller 82. The guide roller 82 presses against the filter cloth 30. The position sensor 84 can sense the swing position of the fabric support frame 81. When the filter cloth 30 gradually relaxes, the counterweight 83 drives the fabric support frame 81 to rotate under the action of gravity, thereby lifting the filter cloth 30 and increasing the tension of the filter cloth 30; conversely, when the tension of the filter cloth 30 increases, the filter cloth 30 presses against the guide roller 82, correspondingly driving the fabric support frame 81 to rotate in the opposite direction.

[0080] The position sensor 84 senses the swing position of the fabric frame 81 and sends the swing position of the fabric frame 81 to the controller. The controller can determine whether the filter cloth 30 is in a relaxed state based on the swing position. When it is determined that the filter cloth 30 is in a relaxed state, it controls the first traction mechanism 13 and / or the second traction mechanism 40 to adjust the traction speed of the filter cloth 30, thereby adjusting the tension of the filter cloth 30 accordingly, so that the tension of the filter cloth 30 is controlled at an appropriate level, thereby ensuring that the filter cloth 30 has a good folding and forming effect when folded by the folding mechanism 50.

[0084] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
