[0041] First Embodiment

[0042] Referring to Figures 1 to 3 As shown in the figure, it is an automatic dust-free cloth folding device in the first embodiment of the present application, including a workbench 10 and a folding assembly 20; the top of the workbench 10 is provided with a receiving groove 11, the bottom of the receiving groove 11 is provided with a lifting piece 12, and the two side walls of the receiving groove 11 are respectively provided with a first telescopic piece 13; the folding assembly 20 includes a first lifting driving piece 21 and a pressing piece 22 mounted on one end of the first lifting driving piece 21, and the first lifting driving piece moves towards the direction of the lifting piece, when the lifting piece moves below the middle axis of the two first telescopic pieces, the two first telescopic pieces move relatively.

[0043] The first lifting driving piece 21 is used to drive the pressing piece 22 to extrude the lifting piece 12, so as to switch the working state of the lifting piece 12 and the working state of the first telescopic piece 13, wherein the working state of the lifting piece 12 and the first telescopic piece 13 includes the compressed state and the initial state, when the lifting piece 12 is switched from the initial state to the compressed state, the first telescopic piece 13 is switched from the compressed state to the initial state.

[0044] In the embodiment, the length of the accommodating groove 11 is greater than the width of the dust-free cloth to be folded, the width of the accommodating groove 11 is less than the length of the dust-free cloth to be folded, and the restoring elastic force of the first telescopic member 13 is less than the restoring elastic force of the lifting member 12. In actual application, first, the dust-free cloth is laid horizontally on the workbench 10 (that is, the two long edges of the dust-free cloth extend out of the accommodating groove 11 of the workbench 10, and the middle sections of the two wide edges are located on the lifting member 12 in the accommodating groove 11 of the workbench 10), at this time, the workbench 10 is in the initial state (that is, the upper surface of the lifting member 12 is flush with the upper surface of the accommodating groove 11, the first telescopic member 13 is in the compressed state, and the lifting member 12 is in the initial state), then the upper computer controls the first lifting driving member 21 to extend, so that the pressing member 22 presses on the lifting member 12 and also presses on the dust-free cloth on the lifting member 12, thereby causing the lifting member 12 to descend into the accommodating groove 11 together with the dust-free cloth, at this time, the two ends of the dust-free cloth extending out of the lifting member 12 are folded towards the middle, when the pressing member 22 is pressed to the latter half of the stroke, due to the arc-shaped side wall structure of the arc-shaped column 17, the first telescopic member 13 begins to slowly rebound, the arc-shaped column 17 on the first telescopic member 13 extends out, and the lifting member 12 is compressed; when the lifting member 12 descends to below the two sides of the first telescopic member 13 (the predetermined extension amount of the first lifting driving member 21 can be set), the first lifting driving member 21 stops extending, at this time, the first telescopic member 13 returns to the natural state; then the first lifting driving member 21 is controlled to shorten, at this time, the lifting member 12 rises under the action of the restoring force, but since the lifting member 12 will be pressed with the arc-shaped column 17 of the two sides of the first telescopic member 13, and the pressing member 22 has no interference with the arc-shaped column 17, the rising speed of the pressing member 22 will be faster than that of the lifting member 12, that is, the pressing member 22 is separated from the lifting member 12, and the pressing member 22 can be pulled out from the inner side of the folded dust-free cloth, until the pressing member 22 returns to the initial position; during the rising process of the pressing member 22, since the elastic force of the lifting member 12 is greater than that of the first telescopic member 13, the arc-shaped column 17 will be gradually pressed back into the accommodating bin (limiting groove 15), and the folded dust-free cloth is folded towards the middle under the mutual pressing action of the arc-shaped column 17 and the edge of the lifting member 12; when the pressing member 22 returns to the initial position, the two long edges of the dust-free cloth on the pressing block have completed the folding; thereby completing the first folding.

[0045] As shown in Figures 4 to 6 the lifting member 12 includes a first lifting part 121 and a second lifting part 122, the first lifting part 121 is close to the second lifting part 122 and has a second telescopic member 14, the pressing member 22 includes a first pressing plate 221 and a second pressing plate 222, the first pressing plate 221 is connected with the first lifting driving member 21 through a second lifting driving member 23, so that the second pressing plate can move towards the second lifting part independently, when the second pressing plate moves below the middle axis of the second telescopic member, the second telescopic member moves away from the first pressing plate.

[0046] The second lifting driving member 23 is used for driving the first pressing plate 221 to move away from the first lifting part 121, so that the second pressing plate 222 can independently extrude the second lifting part 122, and when the second pressing plate 222 extrudes the second lifting part 122, the working state of the second telescopic member 14 is switched, and the working state of the second telescopic member 14 includes a compression state and an initial state.

[0047] In the actual application process, the host computer controls the second lifting driving member 23 to be shortened, the first pressing plate 221 moves upward, the height difference between the first pressing plate 221 and the second pressing plate 222 is greater than or equal to the height of the first lifting part 121 and does not interfere with the subsequent folding of the dust-free cloth, the electric telescopic member 30 is elongated, the free end of the electric telescopic member 30 is inserted into the blind hole of the first lifting part 121, the first lifting part 121 can be limited to move up and down, the first lifting driving member 21 is elongated, the first pressing plate 221 and the second pressing plate 222 move downward, the second pressing plate 222 extrudes the dust-free cloth folded on the second lifting part 122, and the first lifting part 121 remains stationary, the first lifting part 121 and the second lifting part 122 form a height difference and extrude the dust-free cloth to bend from the center line; when moving to the lower half, the second telescopic member 14 and the two first telescopic members 13 on the three sides of the second lifting part 122 begin to slowly elongate, and the corresponding three arc-shaped columns 17 slowly extend into the containing bin; when the second lifting part 122 is lowered until it is lower than the three arc-shaped columns 17 on the sides (a predetermined elongation of the first lifting driving member 21 can be set), the first lifting driving member 21 stops elongating, the second telescopic member 14 and the two first telescopic members 13 on the three sides of the second lifting part 122 return to the natural state, the first pressing plate 221 is located above the first lifting part 121 and the gap between the two fully meets the free folding of the dust-free cloth, does not interfere with the folding of the dust-free cloth, the first lifting driving member 21 is shortened, the second lifting part 122 rises under the action of the elastic force, but because the second lifting part 122 will be extruded with the three arc-shaped columns 17, the movable plate of the second pressing plate 222 will not interfere with the arc-shaped column 17 due to the retreat, the rising speed of the second pressing plate 222 will be faster than that of the second lifting part 122, that is, the second pressing plate 222 and the second lifting part 122 are separated, the second pressing plate 222 can be pulled out from the inside of the folded dust-free cloth, until the second pressing plate 222 returns to the initial position; during the rising process of the second lifting part 122, because the elastic force of the second lifting part 122 is greater than that of the three elastic telescopic members, the arc-shaped column 17 will be gradually pressed back into the containing bin, and the dust-free cloth will be folded twice under the mutual extrusion of the arc-shaped column 17 and the edge of the second lifting part 122, achieving the effect of automatic folding, replacing manual folding and improving work efficiency and saving labor.

[0048] It is worth mentioning that the first lifting part 121 and the second lifting part 122 are arranged close to each other, and when the first folding is performed, the pressing part 22 simultaneously presses the first lifting part 121 and the second lifting part 122 downward, so that the second telescopic part 14 is kept in a compressed state.

[0049] Further, the two sides of the pressing part 22 are respectively provided with a limiting part 31 through an electric telescopic part 30, the limiting part 31 is matched with the first telescopic part 13, so that when the electric telescopic part 30 switches the working state, the working state of the first telescopic part 13 is switched, wherein the working state of the electric telescopic part 30 includes an elongation state and a shortening state. Specifically, when the electric telescopic part 30 is in the elongation state, the outer side wall of the limiting part 31 is on the same vertical plane as the inner wall of the accommodating groove 11, and when the electric telescopic part 30 is in the shortening state, the outer side wall of the limiting part 31 does not contact the first telescopic part 13.

[0050] Specifically, in application, first, the electric telescopic part 30 is driven to be in the elongation state, so that the outer side wall of the limiting part 31 is on the same vertical plane as the inner wall of the accommodating groove 11, so that when the pressing part 22 performs the first extrusion on the lifting part 12, the outer side of the limiting part 31 is in contact with the inner wall of the accommodating groove 11, facilitating the folding of the dust-free cloth, when the pressing part 22 needs to be retracted, first, the electric telescopic part 30 is retracted to be in the shortening state, at this time, the limiting part 31 is away from the first telescopic part 13, so that the first telescopic part 13 starts to stretch, the arc-shaped column 17 on the first telescopic part 13 folds the dust-free cloth, through the cooperation of the electric telescopic part 30, the limiting part 31 and the first elastic telescopic part, the dust-free cloth is folded more neatly.

[0051] Specifically, the first telescopic part 13 and the second telescopic part 14 each include a limiting groove 15 and an arc-shaped column 17 arranged in the limiting groove 15 (accommodation bin) through a second elastic part 16. More specifically, the cross section of the arc-shaped column 17 is arranged in an arc shape. It can be understood that the limiting groove 15 of the first telescopic part 13 is opened on the workbench 10, and the limiting groove 15 of the second telescopic part 14 is opened on the side of the first lifting part 121 close to the second lifting part 122.

[0052] It is worth mentioning that the side of the second pressing plate 222 close to the first pressing plate 221 is also understood as the limiting piece 31 matched with the second telescopic piece 14, in specific application, when the second pressing plate 222 extrudes the second lifting part 122 downward, the electric telescopic piece 30 is in initial state, the limiting piece 31 is in the same vertical plane with one side of the second lifting part 122, so that the limiting piece 31 extrudes the second telescopic piece 14 downward, when the second pressing plate 222 needs to be retracted, the electric telescopic piece 30 is first retracted to shorten, at this time, the limiting piece 31 is away from the second telescopic piece 14, so that the second telescopic piece 14 starts to stretch, at this time, the arc-shaped column 17 on the second telescopic piece 14 folds the dust-free cloth, through the cooperation of the electric telescopic piece 30, the limiting piece 31 and the second elastic telescopic piece, the dust-free cloth is folded more neatly the second time. In the embodiment, the electric telescopic piece 30 is an electric telescopic rod 211.

[0053] Specifically, two first telescopic pieces 13 are provided, and the four first telescopic pieces 13 are symmetrically arranged in pairs, so that the two sides of the first lifting part 121 and the second lifting part 122 each correspond to a first telescopic piece 13. Two first telescopic pieces 13 respectively cooperate with the two sides of the first lifting part 121. The other two first telescopic pieces 13 respectively cooperate with the two sides of the first lifting part 121.

[0054] Further, the first lifting part 121 and the second lifting part 122 each include a first elastic piece 123 and a laying plate 124 fixed to one end of the first elastic piece 123, wherein the sum of the sizes of the two laying plates 124 corresponds to the size of the accommodating groove 11. In the embodiment, the first elastic piece 123 and the second elastic piece 16 are both return springs.

[0055] Specifically, the folding device further includes a rack 40, the rack 40 includes a bottom plate 41, a top plate 42 and a plurality of vertical columns 43 arranged between the bottom plate 41 and the top plate 42, the workbench 10 is arranged on the bottom plate 41, and the first lifting driving piece 21 is installed on the top plate 42. The first lifting driving piece 21 includes an electric telescopic rod 211 and a mounting plate 212 connected with the electric telescopic rod 211, a side wall of the mounting plate 212 is in sliding connection with the vertical columns 43; the mounting plate 212 is arranged between all the vertical columns 43, and a slide groove 431 is formed in a side edge of the vertical column 43 close to the mounting plate 212, and the slide groove 431 is in sliding connection with the side wall of the mounting plate 212. The mounting plate 212 is connected with the first pressing plate 221 through the second lifting driving piece 23, and the mounting plate 212 is connected with the second pressing plate 222 through the supporting rod.

[0056] Further, one side of the workbench 10 is provided with a telescopic limiting piece 5031 which can pass through the side wall of the workbench 10 and enter the accommodating groove 11 to limit the first lifting part 121, so as to prevent the first lifting part 121 from lifting when the dust-free cloth is folded for the second time, thereby improving the satisfaction of the second folding. In the embodiment, the telescopic limiting piece 5031 is an electric telescopic rod 211.

[0057] The principle of folding the dust-free cloth by using the folding device is as follows:

[0058] 1. Complete cleaning of the device;

[0059] 2. The rectangular dust-free cloth to be folded is laid flat on the first lifting part 121 and the second lifting part 122, the length of the dust-free cloth is less than the length of the first lifting part 121 and the second lifting part 122 added transversely, the width of the dust-free cloth is greater than the longitudinal width of the first lifting part 121 or the second lifting part 122, so that the two long edges of the dust-free cloth completely extend out of the first lifting part 121 and the second lifting part 122, and the middle sections of the two wide edges are located on the first lifting part 121 and the second lifting part 122, and the two ends of the wide edges extend out of the first lifting part 121 and the second lifting part 122;

[0060] 3. In the initial state, the upper surfaces of the first lifting part 121 and the second lifting part 122 are flush with the upper surface of the rectangular groove, the lower surfaces of the first pressing plate 221 and the second pressing plate 222 are flush, the outer contour of the limiting piece 31 connected with the first pressing plate 221 is consistent with the horizontal contour of the first lifting part 121, the outer contour of the limiting piece 31 connected with the second pressing plate 222 is consistent with the horizontal contour of the second lifting part 122, and all the arc-shaped columns 17 are located in the corresponding accommodating bin (limiting groove 15) and abut against the laying plate 124 of the corresponding first lifting part 121;

[0061] 4. The upper computer controls the first lifting driving piece 21 to extend, the limiting piece 31 connected with the first pressing plate 221 presses the dust-free cloth on the first lifting part 121, the limiting piece 31 connected with the second pressing plate 222 presses the dust-free cloth on the second lifting part 122, and they are simultaneously contacted and pressed downward, so that the first lifting part 121 and the second lifting part 122 are lowered, and the two extended long edges of the dust-free cloth are folded and close to each other;

[0062] 5. When the downward pressing is to the latter half, due to the arc-shaped side wall structure of the arc-shaped column 17, the spring A (elastic member) of the first telescopic piece 13 starts to slowly rebound, the arc-shaped columns 17 on both sides of the first lifting part 121 and the second lifting part 122 slowly extend out of the accommodating bin, the spring B (elastic member) of the first lifting part 121 and the second lifting part 122 is compressed, but the spring A (elastic member) of the second telescopic piece 14 between the first lifting part 121 and the second lifting part 122 is not deformed.

[0063] 6、When the first lifting part 121 and the second lifting part 122 are lowered until below the two arc-shaped columns 17 (a predetermined extension amount of the first lifting drive 21 can be set), the first lifting drive 21 stops extending, at which time the spring A returns to the natural state, and the upper computer controls the electric telescopic part 30 on both sides of the first lifting part 121 and the second lifting part 122 to shorten, and the limiting part 31 retreats until the limiting part 31 does not interfere with the arc-shaped column 17 in the natural state of the spring A;

[0064] 7、At this time, the first lifting drive 21 shortens, and the first lifting part 121 and the second lifting part 122 rise under the action of the elastic force of the spring B, but since the first lifting part 121 and the second lifting part 122 will be pressed against the two arc-shaped columns 17, and the limiting part 31 of the first pressing plate 221 and the second pressing plate 222 retreats and does not interfere with the arc-shaped column 17, the rising speed of the first pressing plate 221 and the second pressing plate 222 will be faster than that of the first lifting part 121 and the second lifting part 122, that is, the first pressing plate 221 and the second pressing plate 222 are separated from the first lifting part 121 and the second lifting part 122, respectively, and the first pressing plate 221 and the second pressing plate 222 can be pulled out from the inner side of the folded dust-free cloth until the first pressing plate 221 and the second pressing plate 222 return to the initial position;
