[0007] The clipping device comprises a conveying part and a clipping part, wherein the conveying part transports the stacked towels to the clipping part through a first driving mechanism, and the towels are bound by a paper clipping machine;

[0008] The stacking device includes a lifting column and a pair of receiving plates. The first conveying device includes a plurality of conveyor belts arranged in parallel and at intervals. The plurality of lifting columns are correspondingly arranged in the intervals between the plurality of conveyor belts and are lifted and lowered by a second driving mechanism. The pair of receiving plates are driven by a third driving mechanism to move away from or close to the center of the first conveying device.

[0009] Preferably, the receiving plate comprises a plurality of support plates arranged in parallel and at intervals, wherein the support plates extend toward the center of the first conveying device, and when the lifting columns are raised, the plurality of support plates are cross-arranged with the plurality of lifting columns.

[0010] Preferably, the pair of receiving plates are symmetrical with respect to the first conveying device, and when the pair of receiving plates move toward each other, the corresponding supporting plates abut against each other.

[0011] Preferably, there is a height difference between the support plate and the conveyor belt, and when the towels are not moved onto the first conveying device, the heights from top to bottom are the support plate, the conveyor belt, and the lifting column.

[0012] Preferably, the transfer plate includes a plurality of spaced-apart connecting plates, wherein the width of the connecting plates is smaller than the space between two adjacent conveyor belts, so that the connecting plates can be inserted in the space corresponding to the adjacent conveyor belts.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with specific embodiments:

[0031] like Figure 1-Figure 4 As shown, a towel folding and carding machine comprises a stacking device 1, a first conveying device 2, a second conveying device 3, a third conveying device 4, a transfer plate 7 and a carding device 8. The third conveying device 4, the second conveying device 3 and the first conveying device 2 are connected in sequence. The towel first passes through the third conveying device 4, and is folded for the first time by the first folding mechanism 5. Then, the towel passes through the second conveying device 3, and is folded for the second time by the second folding mechanism 6. Finally, the towel enters the first conveying device 2. The multiple towels conveyed to the first conveying device 2 are stacked by the stacking device 1. Then, the first conveying device 2 continues to convey the stacked towels forward. The transfer plate 7 moves the stacked towels to the carding device 8. The conveying part 81 clamps and moves the stacked towels to the carding part 82. Finally, the stacked towels are bound by the carding machine 9.

[0032] The first conveying device 2 includes a plurality of conveyor belts 21 arranged in parallel and at intervals, and a plurality of lifting columns 11 are correspondingly arranged between the intervals of the plurality of conveyor belts 21. The second driving mechanism 13 drives the lifting columns 11 to perform lifting movements. When the towel moves to the top of the lifting columns 11, the lifting columns 11 lift the towel off the surface of the conveyor belt 21. When the height exceeds the receiving plate 12, the third driving mechanism 14 drives the two receiving plates 12 to approach the towel and move to the bottom of the towel. At this time, the lifting columns 11 descend and wait for the next towel to arrive at the position. The towel falls on the receiving plate 12. When the lifting columns 11 lift the towel up again When the towels are stacked, the receiving plate 12 is driven by the third driving mechanism 14 to move away from the conveyor belt 21, so that the towels on the receiving plate 12 fall down, completing the stacking of two towels. Repeating the above movement can eventually complete the stacking of multiple towels. Because towels are easily subjected to friction and extrusion during transportation and stacking, which may cause fiber damage or deformation, stacking by directly dropping them reduces friction and collision between towels, reduces the risk of damage, and helps to maintain the integrity and service life of the towels. At the same time, it can also ensure that the towels can be stacked together quickly and neatly, which is convenient for subsequent transportation and binding, and improves stacking efficiency.

[0033] Specifically, the receiving plate 12 includes a plurality of support plates 121 arranged in parallel and at intervals, and the support plates 121 extend toward the center of the first conveying device 2, so that the support plates 121 can lift the towels. When the two receiving plates 12 move toward each other, the corresponding support plates abut against each other. When the ends of the two symmetrical support plates 121 abut against each other, a more stable support structure is formed, which can prevent the towels from collapsing or shifting during the stacking process, and prevent the towels from deforming on the two receiving plates 12.

[0034] Furthermore, when the lifting column 11 is raised, the plurality of support plates 121 and the lifting column 11 are cross-arranged to ensure that the lifting column 11 will not collide or interfere with the support plates 121 during the rising or falling process, thereby affecting the stacking of towels and the stability of the equipment.

[0035] In this embodiment, there is a height difference between the support plate 121 and the conveyor belt 21. When the towels are not moved onto the first conveyor device 2, the heights of the support plate 121, the conveyor belt 21, and the lifting column 11 are arranged from top to bottom. The lifting column 11 lifts the towels on the conveyor belt 21 through the height difference, and the lifted towels are supported by the support plate 121, so that multiple towels are stacked without displacement in the horizontal direction, thereby avoiding mutual friction between the towels and improving product quality.

[0036] Furthermore, if Figure 8 As shown, the transfer plate 7 includes a plurality of connecting plates 72 arranged at intervals, and the width of the connecting plates 72 is smaller than the interval between two adjacent conveyor belts 21. When the towels are stacked, driven by the driving device 71, the plurality of connecting plates 72 are located in the intervals of the conveyor belts 21, and then the towels are lifted and placed on the placement plate 812. At this time, the towels are still on the conveyor belt 21, and the connecting plates 72 are inserted between the intervals of the conveyor belt 21 to prevent the connecting plates 72 from being located at the end of the conveyor belt 21, so that the towels are partially located on the conveyor belt 21 and partially on the connecting plates 72, resulting in different forces on the two parts of the towels, which are offset due to the influence of friction, causing the stacked towels to be misplaced or tipped over.

[0037] In this embodiment, Figure 5-Figure 7 As shown, the conveying portion 81 includes a pair of clamping assemblies 811 and a placement plate 812, and a plurality of parallel placement holes 813 are provided on the prevention hole, and the plurality of placement holes 813 correspond one-to-one to the plurality of connecting holes. When the transfer plate 7 moves the towel to the placement plate 812, the connecting plate 72 passes through the placement hole 813 to make the towel fall on the placement plate 812. In order to enable the transfer plate 7 to move out of the placement hole 813 without touching the towel after completing the transfer of the towel, the length of the placement hole 813 is greater than the sum of the lengths of the connecting plate 72 and the towel, thereby preventing the towel from being offset, causing friction or tipping over.

[0038] Furthermore, the placement plate 812 is provided with grooves 814 on both side edges parallel to the direction of movement of the towel. When the transfer plate 7 places the towel on the placement plate 812, the two side edges of the towel are respectively located on the two grooves 814. A pair of clamping assemblies 811 can clamp the towel and move it toward the punching part 82 under the drive of the first driving mechanism 83 without colliding with the towel when clamping it, causing the towel to tilt or shift, making the stacked towels uneven and affecting the binding of the towels. The punching part 82 is located directly below the cardboard punching machine 9. The cardboard punching machine 9 moves downward to bind the cardboard on the stacked towels to complete the binding.

[0039] The implementation principle of this embodiment:

[0040] When folding and punching paper of the towel, the towel passes through the third conveying device 4 and the second conveying device 3, and passes through the first folding mechanism 5 and the second folding mechanism 6 to complete the first folding and the second folding of the towel. After the towel that has completed the two foldings enters the first transmission device, it moves only above the lifting column 11 under the transmission of the conveyor belt 21. The lifting column 11 lifts the towel under the drive of the second driving mechanism 13. When it exceeds the receiving height, the receiving plate 12 approaches the conveyor belt 21 under the drive of the third driving mechanism 14 and is located at the bottom of the towel. Then the lifting column 11 descends to make the towel fall on the receiving plate 12. When the next towel moves above the lifting column 11, the lifting column 11 lifts the towel again. At this time, the receiving plate 12 is away from the conveyor belt 21 and makes the towel fall on the lifting column 11. After the stacking of two towels is completed, when the height of the lifting column 11 exceeds the receiving plate 12 again, the receiving plate 12 moves toward each other again to lift the towels, and the above movement is repeated until the stacking of the towels is completed. After completion, the lifting column 11 descends and places the stacked towels on the conveyor belt 21, and the conveyor belt 21 continues to drive the towels to move. The transfer plate 7 is inserted in the gap between the transmission belts under the drive of the driving device 71, and lifts the towels away from the transmission belts. When the transfer plate 7 moves to above the placement plate 812, the connecting plate 72 passes through the placement hole 813 to place the stacked towels on the placement plate 812, and the clamping assembly 811 passes through the two slots 814 and is driven by the first driving mechanism 83 to clamp and move the towels to the punching part 82, and then the paper punching machine 9 binds the paper jams to the stacked towels.

[0041] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
