Description

Technical Field

[0001] This invention relates to the field of tablecloth production technology, and in particular to a continuous inspection, folding, and packaging device for tablecloths. Background Technology

[0002] Tablecloths are used to cover tabletops or desktops to prevent stains or enhance their appearance. During tablecloth production, after cutting and sealing to the required size and specifications, the tablecloths undergo soiling and damage inspection. Only after passing this inspection are they folded and packaged for warehousing and transportation. Currently, the inspection, folding, and packaging of tablecloths are mostly carried out separately and rely on manual visual inspection and operation. This not only affects the accuracy of the results but also results in long hours of labor, low efficiency, and an inability to guarantee the continuity of tablecloth inspection, folding, and packaging. Summary of the Invention

[0003] The purpose of this invention is to provide a continuous inspection, folding and packaging device for tablecloths, which can continuously and automatically inspect, fold and package tablecloths, ensuring the accuracy of inspection results, the quality of folding and packaging, realizing continuous production of tablecloths, improving production efficiency and reducing manual labor intensity.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A continuous inspection, folding, and packaging device for tablecloths includes an inspection mechanism, a sorting mechanism, a folding mechanism, a packaging mechanism, and a control console, wherein the control console is controlled and connected to the inspection mechanism, the sorting mechanism, the folding mechanism, and the packaging mechanism.

[0006] The folding mechanism includes an operating table. At one end of the operating table near the loading end, there are loading clamps on both sides along its length direction, which slide along the length of the operating table. At both ends of the operating table are horizontal guide frames arranged along its width direction. Each horizontal guide frame has end folding clamps at both ends, which slide along the length of the horizontal guide frame. On both sides of the operating table are side guide frames arranged along its length direction, and two horizontal guide frames slide along the length of the side guide frames. Between the two horizontal guide frames are two side folding clamps, each close to and located between the side guide frames, which slide along the length of the horizontal guide frames and are mounted on the operating table.

[0007] The testing mechanism includes a testing frame disposed on one side of the operating table, and a testing component disposed on the testing frame along the width direction of the operating table and located above the operating table. The testing component is slidably mounted on the testing frame along the length direction of the operating table.

[0008] The sorting mechanism includes a sorting box located on one side of the operating table, and a sorting component that cooperates with the sorting box is provided on the operating table. The detection component is controlled and connected to the sorting component via a control console.

[0009] The packaging mechanism includes a packaging component disposed at the end of the operating table away from the feeding clamp, and a discharging component that cooperates with the packaging component and the operating table.

[0010] The end folding clamp includes an end folding seat slidably mounted on a horizontal guide frame. An end lifting seat is vertically slidably mounted on the end folding seat. An end suction plate is rotatably mounted on the side of the end lifting seat away from the side guide frame it is close to. The end suction plate is rotatably mounted on the end lifting seat, and its rotation axis is set along the length direction of the horizontal guide frame.

[0011] The side folding clamp includes a side folding seat that is slidably mounted on the operating table along the length of the horizontal guide frame. A side lifting seat is vertically slidably mounted on the side folding seat. A side suction plate that is eccentrically mounted on the side lifting seat along the length of the side guide frame is arranged along the length of the side guide frame and is located on the side of the side folding clamp away from the side guide frame that is close to it.

[0012] By adopting the above technical solution, initially, the two end-folding clamps on the horizontal guide near the feeding end slide closer to each other to make way for the feeding clamp. The feeding clamp clamps the end of the tablecloth from the feeding end and slides along the length of the operating table to lay the tablecloth flat on the operating table. Then, according to the length and width of the tablecloth, the positions of the four end-folding clamps are adjusted by sliding the end-folding clamps along the horizontal guide and the horizontal guide along the side guide, so that they correspond one-to-one with the four corners of the tablecloth. By vertically sliding the end suction plates, the end suction plates of the two end-folding clamps near the feeding end of the operating table are positioned above the tablecloth, and the end suction plates of the two end-folding clamps away from the feeding end of the operating table are positioned below the tablecloth. The tablecloth is fixed by the four corners of the tablecloth using the four end-folding clamps. After the feeding clamp delivers the tablecloth, it resets to avoid affecting the folding of the tablecloth by the four end-folding clamps. At the same time, by fine-tuning the end-folding clamps along the length of the horizontal guide and the horizontal guide along the length of the side guide, the tablecloth is neatly flattened.

[0013] The drive detection component slides along the length of the operating table. As the detection component slides from one end of the operating table to the other, it slides over the tablecloth and detects defects on the surface of the tablecloth. If a defect is detected, the communication feedback controls the sorting component to work, remove the tablecloth with defects and put it into the sorting box. If no defects are detected, the end folding clamp and the side folding clamp work together to fold the tablecloth.

[0014] When folding the tablecloth, the end suction plates in the two end clamps near the loading end of the operating table rotate 180°, flipping the lower surface of the tablecloth end near the loading end of the operating table upwards. That is, the end clamps at that point change from being above the tablecloth to being in the middle of the tablecloth. The horizontal guide frame near the loading end of the operating table moves away from the loading end along the side guide frame, pulling one end of the tablecloth to the other end until the two ends of the tablecloth are aligned. The end suction plates release the tablecloth and move it out from between the two layers of the tablecloth. Then, the end suction plates move upwards and the corresponding horizontal guide frame slides back to the loading end of the operating table, completing the first fold in the length direction of the tablecloth. The tablecloth is now folded into two layers.

[0015] The end suction plates in the two end clamps away from the loading end of the operating table are rotated 180°, turning the lower surface of the tablecloth away from the loading end of the operating table upwards. That is, the end clamps at this point change from being above the tablecloth to being above the tablecloth. At the same time, the two side suction plates fix the two layers of tablecloth at the end closest to the loading end of the operating table. The entire horizontal guide frame away from the loading end of the operating table moves along the side guide frame towards the loading end, moving one end of the tablecloth to the other end until the two ends of the tablecloth are aligned. The end suction plates are released and the tablecloth falls. Then the entire horizontal guide frame slides back to the loading end away from the operating table, completing the second fold along the length of the tablecloth. The tablecloth is now folded into four layers.

[0016] Similarly, when using the side folding clips to fold the tablecloth in the width direction, the side folding clips adhere to the lower left surface of the tablecloth, the side suction plate rotates eccentrically, and then the left side of the tablecloth is pulled along the width direction of the worktable by sliding the left side folding seat, aligning the right side of the tablecloth with the left side. The side suction plate releases the tablecloth and the left side folding seat returns to its original position, completing the first fold in the width direction of the tablecloth, folding the tablecloth into eight layers. Similarly, the right side folding clips adhere to the lower right surface of the tablecloth, the corresponding side suction plate rotates eccentrically, and then the right side of the eight-layer tablecloth is pulled along the width direction of the worktable by sliding the right side folding seat, aligning the right side with the left side. After the side suction plate releases, the right side folding clip returns to its original position, completing the second fold in the width direction of the tablecloth, folding the tablecloth into sixteen layers, thus completing the tablecloth folding process.

[0017] The unloading component moves the folded tablecloth from the operating table to the packaging component, which then packages the folded tablecloth for warehousing and transportation.

[0018] This invention establishes an automated production line for tablecloth inspection, folding, and packaging by setting up a folding mechanism including an operating table, a feeding clamp, a horizontal guide frame, an end folding clamp, a side guide frame, and a side folding clamp; an inspection mechanism including an inspection frame and inspection components; a sorting mechanism including a sorting box and sorting components; and a packaging mechanism including an output component and a packaging component. The inspection mechanism, sorting mechanism, folding mechanism, and packaging mechanism are controlled and linked by a control console to achieve automated operation and linkage. This sequentially and continuously realizes the feeding and flattening of tablecloths, defect detection, sorting of defective tablecloths, folding of defect-free tablecloths, and output and packaging of folded tablecloths. This ensures the accuracy of inspection results, the quality of folding and packaging, improves production efficiency, and reduces manual labor intensity.

[0019] Furthermore, the detection component includes a detection plate arranged along the width direction of the operating table, and the detection plate is slidably mounted on the detection frame along the length direction of the operating table; a plurality of image acquisition devices and light emitters are arranged along the length direction of the lower end face of the detection plate, the image acquisition devices and light emitters are arranged at intervals, and the field of view of the plurality of image acquisition devices and the illumination range of the light emitters both cover the width direction of the operating table; a processor is provided on the control console, the plurality of image acquisition devices are communicatively connected to the processor, and the processor is connected to the sorting component for feedback control.

[0020] By adopting the above technical solution, after the tablecloth is flattened, the detection plate slides along the length of the operating table on the detection frame. The image acquisition device acquires image information of the tablecloth surface from above at a certain frequency according to the moving speed of the detection plate, and transmits it to the processor for image processing to obtain information on tablecloth surface defects. Based on the defect information, the sorting component is controlled to work. Based on the visual recognition of the image acquisition device and the data processing of the processor, online detection of tablecloth surface defects is achieved, ensuring the accuracy of defect detection and reducing manual labor intensity. Specifically, the light emitter increases the brightness of the tablecloth surface to ensure the accuracy of the images acquired by the image acquisition device.

[0021] Furthermore, the sorting assembly includes at least two vertically downward-arranged sorting rods, which are vertically slidably mounted above the operating table. The operating table is provided with sorting holes that correspond one-to-one with the sorting rods and penetrate vertically through the operating table. The bottom of the operating table is provided with sorting connectors that correspond one-to-one with the sorting holes. Each sorting connector is detachably equipped with a sorting pipe that corresponds one-to-one with two sorting boxes. The sorting pipe is connected to a negative pressure fan. The sorting connector is provided with a sensor that is communicatively connected to the corresponding negative pressure fan.

[0022] By adopting the above technical solution, based on the defect detection results fed back by the detection component, the feedback control sorting rod moves vertically downwards, inserting the tablecloth into the corresponding sorting hole. When the sensor detects a tablecloth entering the sorting tube, the feedback control activates the negative pressure fan, using negative pressure adsorption to suck the tablecloth from the sorting hole and sorting tube into the corresponding sorting box, thus achieving the sorting of defective tablecloths. Specifically, depending on whether the defect is manageable (i.e., soiled defects or hole defects), the two sorting rods can be controlled to work accordingly, sorting soiled and hole-defective tablecloths into different sorting boxes for subsequent different processing of tablecloths without re-sorting. If defect classification is not required, the two sorting boxes can serve as backups for each other, eliminating the need for frequent replacement.

[0023] Furthermore, the horizontal guide frame is provided with a horizontal guide groove arranged along its length direction, and a horizontal lead screw arranged along its length direction is rotatably installed in the horizontal guide groove. The end fold seats at both ends of the horizontal guide frame are slidably installed in the horizontal guide groove. The horizontal lead screw is threadedly connected to the end fold seats at both ends with opposite thread directions. One end of the horizontal lead screw is connected to a horizontal motor that drives its positioning rotation.

[0024] The side guide frame is provided with an upper side guide groove and a lower side guide groove that are arranged along its length and staggered vertically. The two ends of the horizontal guide frame away from the loading end of the operating table are slidably installed in the upper side guide groove, and the two ends of the horizontal guide frame near the loading end of the operating table are slidably installed in the lower side guide groove. Both the upper side guide groove and the lower side guide groove are provided with a side rack arranged along its length. A side gear that meshes with the corresponding side rack is rotatably installed at one end of the horizontal guide frame. The rotation axis of the side gear is arranged along the length of the horizontal guide frame and is connected to a side motor that drives its rotation.

[0025] By adopting the above technical solution, the end folding seats at both ends of the horizontal guide frame are slidably installed in the horizontal guide groove, so that the end folding clamps can be slidably installed on the horizontal guide frame. Under the limiting and guiding effect of the horizontal guide groove on the end folding seats and the threaded connection between the horizontal screw and the end folding seats, when the horizontal motor drives the horizontal screw to rotate, since the threaded connection between the two end folding seats and the horizontal screw rotates in opposite directions, the two end folding seats can be driven to slide synchronously in opposite directions, so as to adjust the distance between the two end folding clamps. This allows the four corners of tablecloths of different widths to be fixed so that the tablecloths can be flattened and folded. The structure is simple, easy to operate and has a wide range of applications.

[0026] Furthermore, the operating table is provided with a clearance groove that is arranged along its length and cooperates with the side folding clamp. The side folding seat slides in the clearance groove along its length, and each side folding seat is connected to a side folding cylinder that drives its sliding.

[0027] The side folding seat is provided with a vertically arranged side lowering groove, and the side lifting seat is provided with a side lowering block that is vertically slidably installed in the side lowering groove. A vertically arranged side lowering spring is connected between the upper side of the side lowering block and the upper side of the side lowering groove. A side suction block and a side electromagnetic rod that cooperate with each other are respectively provided between the bottom of the side lowering block and the bottom of the side lowering groove.

[0028] By adopting the above technical solution, the side folding seat is slidably installed in the relief groove, allowing the side folding clip to be slidably installed on the operating table along the width direction. The side folding cylinder drives the entire side folding clip to slide along the relief groove, achieving folding of the tablecloth in the width direction. The side lowering block is vertically slidably installed in the side lowering groove, allowing the side lifting seat to be vertically slidably installed on the side folding seat. Under the combined action of the side lowering spring, the side suction block, and the side electromagnetic rod, the height of the side lifting seat, i.e., the side suction plate, can be adjusted and fixed by adjusting the magnetic force of the side electromagnetic rod, so as to move the side suction plate above or below the tablecloth to ensure smooth folding of the tablecloth.

[0029] Furthermore, the side guide frame is provided with a feeding guide groove arranged along its length and located below the lower side guide groove. The feeding clamp includes a feeding seat that is slidably installed in the feeding guide groove along the length of the side guide frame. The feeding seat is provided with a feeding telescopic cylinder arranged along the width of the operating table. The piston rod end of the feeding telescopic cylinder is away from the side guide frame and is provided with a lower suction block. An upper suction block is provided above the lower suction block. The upper suction block is slidably installed on the lower suction block along the length of the side guide frame, and a clamping gap is formed between the lower suction block and the upper suction block. An electromagnetic block is embedded in the lower end face of the upper suction block, and a vertically arranged clamping spring is provided between the upper end of the electromagnetic block and the upper suction block.

[0030] By adopting the above technical solution, the feeding seat is slidably installed in the feeding guide groove, realizing the overall feeding clamp slidingly installed on the side guide frame along the length direction of the side guide frame. The feeding guide groove is located below the lower side guide groove, avoiding interference between the sliding feeding of the feeding clamp and the horizontal guide frame and end clamp. The feeding telescopic cylinder can be used to adjust the distance between the two feeding clamps, enabling the feeding of tablecloths of different widths and improving the applicability. Under normal conditions, the electromagnetic block is de-energized. Under the action of the clamping spring, the lower end face of the upper suction block is away from the upper end face of the lower suction block, and the upper suction block is located to one side of the lower suction block, facilitating the feeding of the tablecloth end into the clamping gap. Once the tablecloth end is fed into the clamping gap, the upper suction block moves to directly above the lower suction block, the electromagnetic block is energized, and under the attraction of the lower suction block, it overcomes the tension of the clamping spring. Under the attraction and fixing action of the electromagnetic block and the lower suction block, the tablecloth end is fixed in the clamping gap, allowing the entire feeding clamp to move along the length direction of the side guide frame and lay the tablecloth flat on the operating table.

[0031] Furthermore, the two sides of the operating table are also provided with support assemblies close to the corresponding side guides. The support assembly includes a support seat that is slidably installed on the side guide along the length direction of the side guide. A support telescopic cylinder that is vertically slidably installed on the support seat along the width direction of the operating table is provided. The piston rod end of the support telescopic cylinder is away from the side guide and is provided with a support bar that is arranged along its length direction.

[0032] By adopting the above technical solution, when folding the tablecloth, the support bracket moves along the length of the side guide until the side of the support bar closest to the direction the tablecloth came from aligns with the folding center line of the tablecloth. The support extension cylinder drives the support bar to move above the tablecloth. In this way, when the tablecloth is folded, the support bar holds the tablecloth in place at the folding center line, ensuring the folding effect of the tablecloth. After folding, the support extension cylinder drives the support bar to move away from the tablecloth, and then the support bracket is moved to the folding center line of the tablecloth for the next time. The above steps are repeated.

[0033] Furthermore, an upper plate assembly is provided on one side of the operating table. The upper plate assembly includes a vertically arranged upper plate frame. An adjustment plate that slides along the length of the operating table is provided at the upper end of the upper plate frame. A horizontally arranged upper plate telescopic cylinder is provided on the adjustment plate. The end of the upper plate telescopic cylinder away from its piston rod is eccentrically mounted on the adjustment plate, and its rotation axis is vertically arranged. A vertically downward-arranged upper plate lifting cylinder is installed at the piston rod end of the upper plate telescopic cylinder. A paper suction plate is installed at the piston rod end of the upper plate lifting cylinder. A cardboard stacking rack that cooperates with the paper suction plate is provided on one side of the upper plate frame.

[0034] By adopting the above technical solution, appropriate cardboard is selected and stacked on the cardboard stacking rack according to the final folded size of the tablecloth. When the tablecloth is folded for the last time along its length, the upper plate assembly places the cardboard at the final folded position of the tablecloth. In this way, through the final fold along the length of the tablecloth and the fold along its width, the cardboard is wrapped inside the tablecloth, using the cardboard to support the tablecloth and prevent it from collapsing or loosening during unloading and packaging, and also preventing the cardboard from detaching from the tablecloth. Specifically, when the upper plate assembly is working, the upper plate telescopic cylinder rotates eccentrically around its rotation axis, and the upper plate lifting cylinder moves vertically downward. The paper suction plate picks up the cardboard stacked on the top layer of the cardboard stacking rack. Then, the upper plate telescopic cylinder rotates eccentrically until the paper suction plate moves the cardboard directly above the tablecloth. Through the movement of the adjusting plate and the extension and retraction of the upper plate telescopic cylinder, the cardboard is moved to the final folded position of the tablecloth. The upper plate lifting cylinder moves vertically downward until the cardboard is in contact with the upper surface of the tablecloth. The paper suction plate releases the cardboard, placing it on the tablecloth, and the upper plate assembly resets.

[0035] Furthermore, the packaging assembly includes a packaging frame disposed at the end of the operating table away from the feeding end. A conveyor belt that moves in a closed loop along the length of the operating table is installed on the packaging frame. An upper packaging roller and a lower packaging roller, with their axes arranged along the width of the operating table and located above and below the conveyor belt, are also rotatably mounted on the packaging frame near the operating table. A sealing plate is vertically slidably mounted on the packaging frame. A rectangular sealing frame is detachably mounted on the bottom of the sealing plate. A heating sealing strip is provided on each of the four sides of the bottom of the rectangular sealing frame. A take-up roller is also provided on the side of the sealing plate away from the upper packaging roller. The take-up roller is parallel to the upper packaging roller and is rotatably mounted on the packaging frame.

[0036] By adopting the above technical solution, the unloading component removes the folded tablecloth from the operating table and feeds it between two layers of unsealed packaging bags loosened by the upper and lower packaging rollers, leaving the tablecloth on the conveyor belt. The conveyor belt moves the tablecloth to below the rectangular sealing frame, and the sealing plate slides vertically downwards until the rectangular sealing frame is in contact with the packaging bag. Under the action of the heated sealing strip, the packaging bag is sealed on all four sides, forming an independent package. The individually packaged tablecloth is then conveyed out by the conveyor belt, and the remaining material after removing the packaging bag is wound up by the take-up roller.

[0037] Furthermore, the operating table is provided with a clearance opening that extends vertically through it and is located between the two side folding clips. A support plate is vertically slidably installed at the clearance opening. The support plate is provided with several support grooves along the width direction of the operating table. The support grooves extend vertically through the support plate and also extend through the support plate on the side near the packaging rack.

[0038] The discharge assembly includes a discharge rack disposed between the operating table and the packaging rack. An eccentrically mounted discharge seat with a vertically aligned rotation axis is mounted on the discharge rack. A horizontally mounted discharge telescopic cylinder is mounted on the discharge seat. A discharge plate is mounted on the piston rod end of the discharge telescopic cylinder. Several discharge slots are horizontally arrayed on the discharge plate along a direction perpendicular to the discharge telescopic cylinder. Each discharge slot penetrates the discharge plate vertically and horizontally, with one end also penetrating the discharge plate away from the discharge seat. The discharge slots and support slots are arranged alternately at intervals. A horizontally mounted pressure plate is provided between the upper packaging roller and the sealing plate. The pressure plate is vertically slidably mounted on the packaging rack.

[0039] By adopting the above technical solution, after the tablecloth is folded, the drive support plate moves vertically upward, lifting the folded tablecloth above the discharge plate. The discharge seat rotates eccentrically, and the discharge telescopic cylinder extends, moving the discharge plate directly below the support plate. The drive support plate moves vertically downward, and under the misalignment of the support groove and the discharge groove, the support plate moves from the discharge groove to below the discharge plate and resets, leaving the folded tablecloth on the discharge plate. The discharge seat rotates eccentrically, and the discharge telescopic cylinder retracts, moving the folded tablecloth close to the conveyor belt. The discharge telescopic cylinder extends, feeding the tablecloth between two layers of unsealed packaging bags loosened by the upper and lower packaging rollers. The pressure plate moves vertically downward, pressing down on the tablecloth. After the discharge telescopic cylinder retracts and resets, the tablecloth remains on the conveyor belt. The pressure plate then resets upward, thus discharging the tablecloth.

[0040] In summary, the present invention has the following beneficial effects:

[0041] 1. This invention sets up an automated production line for tablecloth inspection, folding, and packaging by setting up a folding mechanism, inspection mechanism, sorting mechanism, and packaging mechanism that are controlled by a console. The folding mechanism sequentially and continuously realizes the feeding and flattening of tablecloths, defect detection, sorting of defective tablecloths, folding of flawless tablecloths, and unloading and packaging of folded tablecloths. This ensures the accuracy of inspection results, the quality of folding and packaging, improves production efficiency, and reduces the intensity of manual labor.

[0042] 2. The folding mechanism of the present invention includes an operating table, a feeding clamp, a horizontal guide frame, end folding clamps, side guide frames, and side folding clamps. The feeding clamp slides along the operating table to feed the tablecloth. The four end folding clamps and the side folding clamps slide along the length and width directions of the operating table, and the tablecloth is folded in the length and width directions by moving the tablecloth. The end folding clamps can slide along the length direction of the horizontal guide frame, and the horizontal guide frame can slide along the length direction of the side guide frame, which can meet the folding requirements of tablecloths of different lengths and widths.

[0043] 3. The present invention provides a support assembly including a support seat, a support telescopic cylinder and a support bar. When the tablecloth is folded in the length direction, the support assembly supports the tablecloth at the center line of the fold to ensure the folding effect of the tablecloth.

[0044] 4. The present invention includes an upper plate assembly comprising an upper plate frame, an adjusting plate, an upper plate telescopic cylinder, an upper plate lifting cylinder, a paper suction plate, and a cardboard stacking rack. The upper plate assembly is used to place cardboard that matches the size of the last folded tablecloth onto the tablecloth before the last side of the tablecloth is folded in the length direction. In this way, the cardboard is wrapped in the tablecloth by folding the last side of the tablecloth in the length direction and folding the tablecloth in the width direction. The cardboard supports the tablecloth and prevents the tablecloth from collapsing and loosening during the unloading and packaging process, and also prevents the cardboard from falling out of the tablecloth.

[0045] 5. The detection mechanism in this invention includes a detection frame, a detection plate, an image acquisition unit, a light emitter, and a processor. The detection plate slides along the length of the operating table on the detection frame. The image acquisition unit acquires image information of the tablecloth surface from above the tablecloth at a certain frequency according to the moving speed of the detection plate, and transmits it to the processor for image processing to obtain information on tablecloth surface defects. Based on the defect information, the sorting component is controlled to work. Based on the visual recognition of the image acquisition unit and the data processing of the processor, online detection of tablecloth surface defects is realized, ensuring the accuracy of defect detection.

[0046] 6. In this invention, a sorting mechanism is set up to directly sort the tablecloths with defects according to the defect detection results of the detection mechanism, and then process them uniformly. Compared with online defect processing, this avoids delaying the folding efficiency and avoids the tablecloths with inconsistent surface quality after online processing.

[0047] 7. The packaging mechanism in this invention includes a packaging component and a discharging component, which realizes automatic discharging and packaging of the folded backing fabric. The operation of the packaging component does not interfere with the operation of the folding mechanism, thus ensuring production efficiency. Attached Figure Description

[0056] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0057] A continuous inspection and folding packaging device for tablecloths, such as Figure 1As shown, the system includes a detection mechanism 01, a sorting mechanism 02, a folding mechanism 03, a packaging mechanism 04, and a control console 05. The control console 05 is connected to the detection mechanism 01, sorting mechanism 02, folding mechanism 03, and packaging mechanism 04. The control console 05 controls the automated operation and linkage of the detection mechanism 01, sorting mechanism 02, folding mechanism 03, and packaging mechanism 04 through automatic control technology such as PLC. The automatic control technology such as PLC is existing technology and will not be described in detail. Furthermore, in this embodiment, the positioning rotation or eccentric rotation of each component is controlled by a motor, which will also not be described in detail; it is only shown schematically in the accompanying drawings.

[0058] Specifically, such as Figure 2 As shown, the folding mechanism 03 includes an operating table 1. At the end of the operating table 1 near the loading end, there are loading clamps 2 located on both sides along its length. The loading clamps 2 slide along the length of the operating table 1, laying the sewn tablecloth flat onto the operating table 1. At both ends of the operating table 1, there are horizontal guide frames 3 arranged along its width. Each horizontal guide frame 3 has end folding clamps 4 at both ends, which are slidably mounted on the horizontal guide frame 3 along its length. On both sides of the operating table 1, there are side guide frames 5 arranged along their length, and the two horizontal guide frames 3 are slidably mounted on the side guide frames 5 along their length. Additionally, between the two horizontal guide frames 3, there are two side folding clamps 6 located near and between the side guide frames 5, which are slidably mounted on the operating table 1 along the length of the horizontal guide frames 3.

[0059] like Figure 2 and Figure 3 As shown, initially, the two end-folding clips 4 on the horizontal guide frame 3 near the feeding end slide closer to each other to make way for the feeding clip 2. The feeding clip 2 clamps the end of the tablecloth from the feeding end and slides along the length of the operating table 1 to lay the tablecloth flat on the operating table 1. Then, according to the length and width of the tablecloth, the positions of the four end-folding clips 4 are adjusted by sliding the end-folding clips 4 along the horizontal guide frame 3 and the horizontal guide frame 3 along the side guide frame 5, so that they correspond one-to-one with the four corners of the tablecloth. The tablecloth is then fixed by the four end-folding clips 4 adsorbing it from the four corners. After the feeding clip 2 delivers the tablecloth, it resets to avoid affecting the folding of the tablecloth by the four end-folding clips 4. At the same time, the tablecloth is neatly flattened by fine-tuning the end-folding clips 4 sliding along the length of the horizontal guide frame 3 and the horizontal guide frame 3 sliding along the length of the side guide frame 5.

[0060] Specifically, such as Figure 2 and Figure 3As shown, a feeding guide groove 56 is provided on the side guide frame 5 along its length direction. The feeding clamp 2 includes a feeding seat 21 that is slidably installed in the feeding guide groove 56 along the length direction of the side guide frame 5. A feeding telescopic cylinder 22 is provided on the feeding seat 21 along the width direction of the operating table 1. The piston rod end of the feeding telescopic cylinder 22 is away from the side guide frame 5 and is provided with a lower suction block 23. An upper suction block 24 is provided above the lower suction block 23. The upper suction block 24 is slidably installed on the lower suction block 23 along the length direction of the side guide frame 5, and a clamping gap 25 is formed between the lower suction block 23 and the upper suction block 24. An electromagnetic block 26 is embedded in the lower end face of the upper suction block 24. A vertically arranged clamping spring 27 is provided between the upper end of the electromagnetic block 26 and the upper suction block 24.

[0061] Among them, such as Figure 2 and Figure 3 As shown, in order to achieve the sliding installation of the upper suction block 24, a micro groove 231 is provided on the lower suction block 23 along the length direction of the feeding guide groove 56. A micro guide block 241 is provided on one side of the upper suction block 24, which is slidably installed in the micro groove 231. A micro electromagnetic rod 242 is provided on the feeding end of the micro guide block 241 near the operating table 1 and the end of the micro groove 231 near it respectively. A micro tension spring 243 is connected between the other end of the micro guide block 241 and the end of the micro groove 231 near it. When the micro electromagnetic rod 242 is de-energized, the upper suction block 24 is located above the lower suction block 23 under the action of the micro tension spring 243.

[0062] like Figure 2 and Figure 3 As shown, based on the width of the tablecloth, the distance between the two feeding clamps 2 is adjusted using the feeding telescopic cylinder 22. The electromagnetic block 26 and the miniature electromagnetic rod 242 are de-energized. Under the action of the miniature tension spring 243 and the clamping spring 27, the upper suction block 24 is positioned above one side of the lower suction block 23, and the lower end face of the electromagnetic block 26 is far away from the upper end face of the lower suction block 23, making it easier for the end of the tablecloth to be fed into the clamping gap 25. After the end of the tablecloth is fed into the clamping gap 25, the miniature electromagnetic rod 242 and the electromagnetic block 26 are energized. The upper suction block 24 moves to directly above the lower suction block 23, and under the attraction of the electromagnetic block 26 and the lower suction block 23, it overcomes the tension of the clamping spring 27. Under the attraction and fixing action of the electromagnetic block 26 and the lower suction block 23, the end of the tablecloth is fixed in the clamping gap 25, so that the entire feeding clamp 2 can move along the length direction of the side guide frame 5 and lay the tablecloth flat on the operating table 1.

[0063] Among them, such as Figure 2 and Figure 3As shown, in order to realize the overall sliding of the feeding clamp 2 along the side guide frame 5, the feeding guide groove 56 passes through both sides of the side guide frame 5. The feeding guide groove 56 is provided with a feeding rack 57 arranged along its length direction. The feeding gear 58 that meshes with the feeding rack 57 is rotatably mounted on the feeding seat 21. The rotation axis of the feeding gear 58 is arranged horizontally perpendicular to the feeding rack 57. The feeding gear 58 is connected to a feeding motor 59 that drives its rotation and is located outside the feeding guide groove 56.

[0064] The following describes in detail the specific structure of each component in the inspection mechanism 01, sorting mechanism 02, folding mechanism 03, and packaging mechanism 04, following the sequential inspection, sorting, folding, and packaging processes.

[0065] like Figure 1 and Figure 4 As shown, the detection mechanism 01 includes a detection frame 9 disposed on one side of the operating table 1 and arranged along the length of the operating table 1. A detection component 91 is disposed on the detection frame 9 and arranged along the width of the operating table 1, located above the operating table 1. Specifically, the detection component 91 includes a detection plate 92 arranged along the width of the operating table 1, which is slidably mounted on the detection frame 9 along the length of the operating table 1. Several image acquisition devices 93 and light emitters 94 are disposed on the lower end face of the detection plate 92 along its length. The image acquisition devices 93 and light emitters 94 are spaced apart, and the field of view of the image acquisition devices 93 and the illumination range of the light emitters 94 both cover the width of the operating table 1. A processor 95 is disposed on the control console 05. The image acquisition devices 93 are communicatively connected to the processor 95, and the processor 95 is connected to the sorting mechanism 02 for feedback control.

[0066] like Figure 1 and Figure 4 As shown, after the tablecloth is flattened, the detection plate 92 slides along the length of the operating table 1 on the detection frame 9. The image acquisition unit 93 acquires image information of the tablecloth surface from above at a certain frequency according to the moving speed of the detection plate 92. The light emitter 94 provides sufficient light source brightness for the image acquisition unit 93 to acquire the image. The tablecloth surface image information acquired by the image acquisition unit 93 is transmitted to the processor 95 for image processing to obtain tablecloth surface defect information. Based on the defect information, the sorting component 101 is controlled to work. Based on the visual recognition of the image acquisition unit 93 and the data processing of the processor 95, online detection of tablecloth surface defects is realized, ensuring the accuracy of defect detection and reducing the intensity of manual labor.

[0067] Among them, such as Figure 1 and Figure 4As shown, in this embodiment, the image acquisition device 93 is a high-speed camera, and the light emitter 94 is an illumination lamp. To achieve the movement drive of the detection plate 92, a detection lead screw 96 is rotatably mounted on the detection frame 9 along its length. One end of the detection lead screw 96 is connected to a detection motor 97 that drives its rotation. One end of the detection plate 92 is limited and slidably mounted on the detection frame 9 and threadedly connected to the detection lead screw 96. Furthermore, the processor 95 receiving image information from the image acquisition device 93 and performing image processing to obtain defect information is existing technology. In this embodiment, a fabric area defect identification method disclosed in the invention with authorization publication number CN115330770B can be used to classify defects into dirt defects and hole defects. Further details are not provided in this embodiment.

[0068] like Figure 4 and Figure 5 As shown, the sorting mechanism 02 includes a sorting box 10 disposed on one side of the operating table 1, and a sorting assembly 101 cooperating with the sorting box 10 is disposed above the operating table 1. Specifically, the sorting assembly 101 includes two vertically downward-arranged sorting rods 102, and each sorting rod 102 is connected to a vertically downward-arranged sorting lifting cylinder 1022 at its upper end. The processor 95 (marked in...) Figure 1 The sorting rod 1022 is connected to the sorting lifting cylinder 1022 for communication control. Above the side guide frame 5 is a sorting frame 1021 with an L-shaped structure and an opening facing downwards. The sorting lifting cylinder 1022 is installed on the corresponding sorting frame 1021, enabling the vertical sliding installation of the sorting rod 102. The operating table 1 has sorting holes 12 that correspond one-to-one with the sorting rods 102 and vertically penetrate the operating table 1. At the bottom of the operating table 1 is a sorting connector 103 that communicates one-to-one with the sorting holes 12. Figure 6 (There are also markings in the middle), the sorting connector 103 is detachably installed with sorting pipes 105 that are connected to the two sorting boxes 10 respectively. The sorting pipes 105 are connected to negative pressure fans 106, and the sorting connector 103 is equipped with a sensor 104 that is connected to the corresponding negative pressure fans 106 for communication control.

[0069] like Figure 4 and Figure 5As shown, based on the detection results of dirt or hole defects by the detection component 91, the corresponding sorting lifting cylinder 1022 is controlled to drive the sorting rod 102 to move vertically downward, inserting the tablecloth into the corresponding sorting hole 12. When the sensor 104 detects that a tablecloth has entered the sorting tube 105, the negative pressure fan 106 is controlled to work, using negative pressure adsorption to suck the tablecloth from the sorting hole 12 and the sorting tube 105 into the corresponding sorting box 10, thus achieving the sorting of defective tablecloths. Dirty and defective tablecloths and tablecloths with holes are sorted into different sorting boxes 10 respectively, so that tablecloths with different defects can be processed differently later without needing to be sorted again. If it is not necessary to classify according to defects, the two sorting boxes 10 can be used as backups for each other, without frequent replacement.

[0070] In this embodiment, as Figure 2 and Figure 3 As shown, the end folding clamp 4 includes an end folding seat 41 slidably mounted on the horizontal guide frame 3. An end lifting seat 42 is vertically slidably mounted on the end folding seat 41, and the end lifting seat 42 is connected to an end lifting cylinder 43 that drives its vertical sliding. An end suction plate 44 is rotatably mounted on the side of the end lifting seat 42 away from the side guide frame 5 that is close to it. The end suction plate 44 is rotatably mounted on the end lifting seat 42, and its rotation axis is set along the length direction of the horizontal guide frame 3 and connected to a micro motor that drives its rotation. Among them, the end suction plate 44 near the feeding end is slightly smaller than the end suction plate 44 away from the feeding end to avoid interference between the end folding clamps 4 at both ends of the operating table 1 during operation.

[0071] like Figure 3 As shown, the side folding clamp 6 includes a side folding seat 61 slidably mounted on the operating table 1 along the length of the horizontal guide frame 3. A side lifting seat 64 is vertically slidably mounted on the side folding seat 61. A side suction plate 69, eccentrically rotatably mounted on the side lifting seat 64, is arranged along the length of the side guide frame 5. The eccentric rotation axis of the side suction plate 69 is arranged along the length of the side guide frame 5 and is located on the side of the side folding clamp 6 away from the side guide frame 5 that is close to it. The end suction plate 44 and the side suction plate 69 utilize vacuum adsorption to move away from the adsorption tablecloth, and are connected to a miniature vacuum machine. This is existing technology and is only briefly illustrated in the figure.

[0072] like Figure 3As shown, to achieve vertical sliding of the drive side lifting seat 64, the side folding seat 61 is provided with a vertically arranged side lowering groove 63. The side lifting seat 64 is provided with a side lowering block 65 vertically slidably installed within the side lowering groove 63. A vertically arranged side lowering spring 66 connects the upper side of the side lowering block 65 and the upper side of the side lowering groove 63. A side suction block 67 and a side electromagnetic rod 68, respectively cooperating with each other, are provided between the bottom of the side lowering block 65 and the bottom of the side lowering groove 63. Additionally, the operating table 1 is provided with a clearance groove 11 arranged along its length and cooperating with the side folding clip 6. The side folding seat 61 slides within the clearance groove 11 along its length, and each side folding seat 61 is connected to a side folding cylinder 62 that drives its sliding. Normally, the entire side folding clip 6 is located within the clearance groove 11, below the upper surface of the operating table 1, to avoid interference or affecting the neatness of the tablecloth during folding.

[0073] like Figure 2 or Figure 3 As shown, in order to realize the sliding of the drive end folding clamp 4 along the horizontal guide frame 3, a horizontal guide groove 31 is provided on the horizontal guide frame 3 along its length direction. A horizontal lead screw 32 along its length direction is rotatably installed in the horizontal guide groove 31. The end folding seats 41 at both ends of the horizontal guide frame 3 are slidably installed in the horizontal guide groove 31. The horizontal lead screw 32 is threadedly connected to the end folding seats 41 at both ends and the threads are opposite in direction. One end of the horizontal lead screw 32 is connected to a horizontal motor 33 that drives its positioning rotation.

[0074] like Figure 2 and Figure 3 As shown, to enable the horizontal guide frame 3 to slide along the length of the side guide frame 5, an upper side guide groove 51 and a lower side guide groove 52 are provided on the side guide frame 5, which are arranged along its length and staggered vertically. The lower side guide groove 52 is located above the feeding guide groove 56. The two ends of the horizontal guide frame 3 away from the feeding end of the operating table 1 are slidably installed in the upper side guide groove 51, and the two ends of the horizontal guide frame 3 near the feeding end of the operating table 1 are slidably installed in the lower side guide groove 52. A side rack 53 is provided in both the upper side guide groove 51 and the lower side guide groove 52, arranged along its length. A side gear 54 is rotatably mounted on one end of the horizontal guide frame 3, meshing with the corresponding side rack 53. The rotation axis of the side gear 54 is arranged along the length of the horizontal guide frame 3 and connected to a side motor 55 that drives its rotation.

[0075] like Figure 2 and Figure 3As shown, when laying and stretching the tablecloth, the vertical sliding of the end suction plate 44 causes the end suction plate 44 of the two end folding clamps 4 near the feeding end of the operating table 1 to be positioned above the tablecloth, and the end suction plate 44 of the two end folding clamps 4 away from the feeding end of the operating table 1 to be positioned below the tablecloth. The tablecloth is fixed by adsorbing it from the four corners of the tablecloth using the four end folding clamps 4. After the feeding clamp 2 delivers the tablecloth, it resets to avoid affecting the folding of the tablecloth by the four end folding clamps 4. At the same time, the tablecloth is neatly stretched flat by the fine adjustment of the end folding clamps 4 sliding along the length of the horizontal guide 3 and the fine adjustment of the horizontal guide 3 sliding along the length of the side guide 5.

[0076] like Figure 2 and Figure 3 As shown, in this embodiment, the tablecloth is folded in two equal parts in the length direction and in two equal parts in the width direction. Folding in the length direction means reducing the length of the tablecloth, and folding in the width direction means reducing the width of the tablecloth.

[0077] like Figure 2 and Figure 3 As shown, the end suction plates 44 in the two end folding clamps 4 near the loading end of the operating table 1 are rotated 180°, turning the lower surface of the tablecloth end near the loading end of the operating table 1 upward, that is, the end folding clamp 4 at this point changes from being above the tablecloth to being in the middle of the tablecloth. The horizontal guide frame 3 near the loading end of the operating table 1 moves away from the loading end along the side guide frame 5, pulling one end of the tablecloth to the other end until the two ends of the tablecloth are aligned. The end suction plates 44 release the tablecloth and move it out from between the two layers of the tablecloth. Then the end suction plates 44 move upward and the corresponding horizontal guide frame 3 slides back to the loading end of the operating table 1, completing the first fold in the length direction of the tablecloth. The tablecloth is folded into two layers.

[0078] like Figure 2 and Figure 3 As shown, the end suction plates 44 in the two end folding clamps 4 away from the loading end of the operating table 1 are rotated 180°, turning the lower surface of the tablecloth away from the loading end of the operating table 1 upward. That is, the end folding clamp 4 at this point changes from being above the tablecloth to being above the tablecloth. At the same time, the suction plates 69 on both sides fix the two layers of tablecloth at the end near the loading end of the operating table 1. The horizontal guide frame 3 away from the loading end of the operating table 1 moves along the side guide frame 5 towards the loading end, moving one end of the tablecloth to the other end until the two ends of the tablecloth are aligned. The end suction plates 44 are released and the tablecloth falls. Then the horizontal guide frame 3 slides back to the loading end away from the operating table 1, completing the second fold in the length direction of the tablecloth. The tablecloth is folded into four layers.

[0079] like Figure 2 and Figure 3As shown, after the left-side folding clip 6 adheres to the lower left surface of the tablecloth, the side suction plate 69 rotates eccentrically. Then, by sliding the left-side folding seat 61 along the width direction of the operating table 1, the left side of the tablecloth is pulled to align with the right side. The side suction plate 69 releases the tablecloth, and the left-side folding seat 61 returns to its original position, completing the first fold in the width direction of the tablecloth, resulting in eight layers. Similarly, the right-side folding clip 6 adheres to the lower right surface of the tablecloth, and the corresponding side suction plate 69 rotates eccentrically. Then, by sliding the right-side folding seat 61 along the width direction of the operating table 1, the right side of the eight-layer tablecloth is pulled to align with the left side. After the side suction plate 69 releases, the right-side folding clip 6 returns to its original position, completing the second fold in the width direction of the tablecloth, resulting in sixteen layers. This completes the folding of the tablecloth. Of course, in other embodiments, the tablecloth can also be folded in other ways by the cooperation of the end folding clip 4 and the side folding clip 6.

[0080] like Figure 3 As shown, to ensure the folding effect when folding along the length of the tablecloth, support components 7 are provided on both sides of the worktable 1 near the corresponding side guides 5. The support components 7 include a support seat 71 that is slidably installed on the side guides 5 along the length of the side guides 5. The support seat 71 is connected to a support adjustment cylinder 72 that drives it to slide. A support telescopic cylinder 73 that is vertically slidably installed on the support seat 71 along the width of the worktable 1 is provided. The support telescopic cylinder 73 is connected to a support lifting cylinder 74 that drives it to slide vertically. The piston rod end of the support telescopic cylinder 73 is away from the side guides 5 and is provided with a support bar 75 that is arranged along its length. When folding the tablecloth, the support seat 71 moves along the length of the side guide 5 until the side of the support bar 75 closest to the direction the tablecloth came from is aligned with the folding center line of the tablecloth. The support lifting cylinder 74 drives the support telescopic cylinder 73 to rise and fall, and the support telescopic cylinder 73 drives the support bar 75 to move above the tablecloth. In this way, when the tablecloth is folded, the support bar 75 holds the tablecloth in place at the folding center line, ensuring the folding effect of the tablecloth. After folding, the support telescopic cylinder 73 moves the support bar 75 away from the tablecloth, and then the support seat 71 is moved to the folding center line of the tablecloth for the next time. The above steps are repeated.

[0081] like Figure 5 As shown, to further ensure the quality of the tablecloth after folding, an upper plate assembly 8 is also provided on one side of the operating table 1. According to the final folded size of the tablecloth, a suitable cardboard is selected and stacked on the cardboard stack rack 86. When the tablecloth is folded for the last time in the length direction, the upper plate assembly 8 is used to place the cardboard at the final folded position of the tablecloth. In this way, through the last fold in the length direction and the fold in the width direction of the tablecloth, the cardboard is wrapped in the tablecloth. The cardboard is used to support the tablecloth, preventing the tablecloth from collapsing and loosening during the unloading and packaging process, and preventing the cardboard from falling out of the tablecloth.

[0082] Specifically, such as Figure 5As shown, the upper plate assembly 8 includes a vertically arranged upper plate frame 81. An adjustment plate 82, which slides along the length of the operating table 1, is located at the upper end of the upper plate frame 81. The adjustment plate 82 is connected to an adjustment telescopic cylinder 821 that drives its horizontal sliding. A horizontally arranged upper plate telescopic cylinder 83 is located on the adjustment plate 82. The end of the upper plate telescopic cylinder 83 away from its piston rod is eccentrically mounted on the adjustment plate 82, and its rotation axis is vertically arranged. A vertically downward-arranged upper plate lifting cylinder 84 is installed at the piston rod end of the upper plate telescopic cylinder 83. A paper suction plate 85 is installed at the piston rod end of the upper plate lifting cylinder 84. A cardboard stacking rack 86, which cooperates with the paper suction plate 85, is located on one side of the upper plate frame 81.

[0083] like Figure 5 As shown, when the upper plate assembly 8 is working, the upper plate telescopic cylinder 83 rotates eccentrically around its rotation axis, and the upper plate lifting cylinder 84 moves vertically downward. The paper suction plate 85 is used to pick up the cardboard stacked on the top layer of the cardboard rack 86. Then, the upper plate telescopic cylinder 83 rotates eccentrically until the paper suction plate 85 moves the cardboard directly above the tablecloth. Through the movement of the adjusting plate 82 and the extension and retraction of the upper plate telescopic cylinder 83, the cardboard is moved to the position where the tablecloth is finally folded. The upper plate lifting cylinder 84 moves vertically downward until the cardboard is in contact with the upper surface of the tablecloth. The paper suction plate 85 releases the cardboard and places it on the tablecloth. The upper plate assembly 8 then resets.

[0084] like Figure 1 As shown, the packaging mechanism 04 includes a packaging component 20 disposed at the end of the operating table 1 away from the feeding clamp 2, and a discharging component 30 that cooperates with the packaging component 20 and the operating table 1. Specifically, as shown... Figure 6 As shown, the operating table 1 is provided with a clearance opening 13 that runs vertically through it and is located between the two side clamps 6. A support plate 14 is vertically slidably installed at the clearance opening 13. The support plate 14 is connected to a discharge lifting cylinder 16 that drives it to slide vertically. Several support grooves 15 are provided on the support plate 14 along the width direction of the operating table 1. The support grooves 15 run vertically through the support plate 14 and also run through the support plate 14 on the side near the packaging rack 201.

[0085] like Figure 7As shown, the packaging assembly 20 includes a packaging frame 201 located at the end of the operating table 1 away from the feeding end. A conveyor belt 202, moving in a closed loop along the length of the operating table 1, is mounted on the packaging frame 201. An upper packaging roller 203 and a lower packaging roller 204, with their axes aligned along the width of the operating table 1 and located above and below the conveyor belt 202 respectively, are also rotatably mounted on the packaging frame 201 near the operating table 1. Single-layer packaging bag rolls are mounted on the upper packaging roller 203 and the lower packaging roller 204. A sealing plate 205 is vertically slidably mounted on the packaging frame 201. A sealing lifting cylinder 2051, vertically downward-oriented and driving the sealing plate 205 to slide vertically, is connected to the upper end of the sealing plate 205. A rectangular sealing frame 206 is detachably mounted at the bottom of the sealing plate 205, and heated sealing strips 207 are detachably mounted on the four sides of the bottom of the rectangular sealing frame 206. A take-up roller 208 is also provided on the side of the sealing plate 205 away from the upper packaging roller 203. The take-up roller 208 is parallel to the upper packaging roller 203 and is rotatably mounted on the packaging frame 201.

[0086] like Figure 6 and Figure 7 As shown, the discharge assembly 30 includes a discharge rack 301 disposed between the operating table 1 and the packaging rack 201. A discharge seat 302 with its rotation axis vertically rotatably mounted on the discharge rack 301 is mounted eccentrically. A horizontally mounted discharge telescopic cylinder 303 is mounted on the discharge seat 302. A discharge plate 304 is mounted on the piston rod end of the discharge telescopic cylinder 303. A plurality of discharge slots 305 are horizontally arranged on the discharge plate 304 along a direction perpendicular to the discharge telescopic cylinder 303. The discharge slots 305 penetrate the discharge plate 304 vertically, and one end of each slot, away from the discharge seat 302, also penetrates the discharge plate 304. The discharge slots 305 and the support slots 15 are arranged alternately. Additionally, a horizontally mounted pressure plate 306 is disposed between the upper packaging roller 203 and the sealing plate 205. The pressure plate 306 is vertically slidably mounted on the packaging rack 201, and its upper end is connected to a vertically downward-mounted pressing lifting cylinder 307.

[0087] like Figure 6 and Figure 7As shown, after the tablecloth is folded, the drive support plate 14 moves vertically upward, lifting the folded tablecloth above the discharge plate 304. The discharge seat 302 rotates eccentrically, and the discharge telescopic cylinder 303 extends, moving the discharge plate 304 directly below the support plate 14. The drive support plate 14 moves vertically downward, and under the misalignment of the support groove 15 and the discharge groove 305, the support plate 14 moves from the discharge groove 305 to below the discharge plate 304 and resets, leaving the folded tablecloth on the discharge plate 304. The discharge seat 302 rotates eccentrically and the discharge telescopic cylinder 303 retracts, moving the folded tablecloth close to the conveyor belt 202. The discharge telescopic cylinder 303 extends and feeds the tablecloth between the two layers of unsealed packaging bags loosened by the upper packaging roller 203 and the lower packaging roller 204. The pressure plate 306 moves vertically downward, pressing down on the tablecloth. Then the discharge telescopic cylinder 303 retracts and resets, leaving the tablecloth on the conveyor belt 202 before resetting.

[0088] like Figure 7 As shown, the conveyor belt 202 moves the tablecloth to below the rectangular sealing frame 206, and the sealing plate 205 slides vertically downward until the rectangular sealing frame 206 is in contact with the packaging bag. Under the action of the heated sealing strip 207, the packaging bag is sealed on all sides and formed into an independent package. The tablecloth after being individually packaged is sent out by the conveyor belt 202, and the remaining material after removing the packaging bag is wound up by the winding roller 208.

[0089] Working principle and usage of this invention:

[0090] The tablecloth is pulled flat onto the operating table 1 by two feeding clamps 2 near the feeding end of the operating table 1. The tablecloth is then fixed to the four corners of the operating table 1 by the adsorption of the four corners of the tablecloth by the four end folding clamps 4 at the four corners of the operating table 1, and the tablecloth is neatly flattened by the fine adjustment of the end folding clamps 4 sliding along the length of the horizontal guide 3 and the fine adjustment of the horizontal guide 3 sliding along the length of the side guide 5.

[0091] As the detection component 91 slides along the length of the operating table 1, it detects defects on the surface of the tablecloth. If a defect is detected, the communication feedback controls the sorting component 101 to work, removing the tablecloth with defects and placing it into the sorting box 10. If no defect is detected, the end folding clamp 4 and the side folding clamp 6 work together to fold the tablecloth.

[0092] By flipping the end suction plate 44 and sliding the end folding clamp 4 along the length of the operating table 1, the tablecloth can be folded multiple times along its length. By flipping the side suction plate 69 and sliding the side folding clamp 6 along the width of the operating table 1, the tablecloth can be folded multiple times along its width, thus folding the tablecloth to a certain size.

[0093] During the folding of the tablecloth along its length, the support assembly 7 tightens the tablecloth from the center line of the fold to ensure a smooth folding effect. Additionally, during the final fold along the length of the tablecloth, the upper plate assembly 8 places the cardboard at the final fold position. Through the final fold along the length of the tablecloth and the fold along its width, the cardboard is wrapped within the tablecloth, providing support and preventing the tablecloth from collapsing or loosening during unloading and packaging, and also preventing the cardboard from detaching from the tablecloth.
