DETAILED DESCRIPTION

[0035] See attached Figures 1 to 11 The utility model is further described in detail for a napkin paper stacking machine.

[0036] A napkin stacking machine comprises a stacking frame 1, wherein the stacking frame 1 is provided with a stacking platform 3 and a feeding channel 2 for conveying napkins; the stacking frame 1 is provided with a partitioning component 4 for separating napkins and a transfer component 5 for transferring the separated napkins to the stacking platform 3;

[0037] The separation assembly 4 includes a separation wheel 42 and a separation driver 41 (wherein the separation driver 41 may be a power source such as a motor or a cylinder). The separation wheel 42 is placed at the outlet of the feed channel 2. The separation driver 41 drives the separation wheel 42 to insert between the napkins on the feed channel 2 to separate the napkins to the transfer assembly 5.

[0038] The separating wheel 42 is provided with a separating leaf 421, which is inclined toward one side of the transfer rack 52, and the thickness of the separating leaf 421 gradually increases along the rotation direction; the separating leaf 421 rotates with the separating wheel 42, pressing the separated napkins toward the transfer rack 52, so that the stack of napkins is turned down together with the transfer rack 52; the separating wheel is provided with a positioning plate 422, and the positioning plate 422 positions the napkins at the outlet of the feed channel 2; after the transfer rack 52 is turned down, the napkins at the outlet of the feed channel 2 are blocked by the positioning plate 422 to prevent the napkins from falling down by themselves;

[0039] The transfer assembly 5 includes a transfer frame 52 and a transfer driver 51 for driving the transfer frame 52 to rotate (wherein the rotation driver may be a power source such as a motor or a cylinder). The transfer frame 52 is arranged opposite to the separation wheel 42. The transfer driver 51 can drive the transfer frame 52 to flip toward the stacking platform 3 to transfer the separated napkins to the stacking platform 3.

[0040] When the stacking machine stacks napkins, the separating wheel 42 placed at the entrance of the feeding channel 2 rotates downward under the drive of the separating driver 41, and the separating wheel 42 is inserted between the napkins in the feeding channel 2. The separating wheel 42 cooperates with the transfer rack 52 to clamp the napkins in front, and automatically separates the napkins at the exit of the feeding channel 2; then, the transfer rack 52 is driven by the transfer driver 51 to flip toward the stacking platform 3, and the separated napkins are placed and transferred to the stacking platform 3, so as to realize automatic stacking of napkins; it replaces the manual stacking of workers, improves the stacking efficiency of napkins, and reduces the production cost of napkins.

[0041] After the transfer of the napkins is completed, the transfer rack 52 is flipped upward under the drive of the transfer driver 51, and the separation wheel 42 will continue to rotate under the drive of the separation driver 41 to separate from the napkins at the outlet of the feed channel 2. At the same time, the napkins in the feed channel 2 will be transported by the outlet and rest against the transfer rack 52 again.

[0042] In order to make the distance between the separating wheel 42 and the feeding channel 2 adjustable, the separating component 4 is vertically slidably arranged on the vertical guide rail 11 of the stacking frame 1 through a vertical slider 43, and the stacking frame 1 is provided with an adjusting hand wheel 13 for driving the separating component 4 to slide; the separating component 4 is driven by the adjusting hand wheel 13 and moves up and down on the vertical guide rail 11 along with the vertical slider 43; it can be adjusted according to the actual height of the napkins, so that the stacking machine can be used to stack napkins of different heights, and has stronger applicability.

[0043] The stacking platform 3 is provided with a first pushing assembly 31, which includes a vertically arranged first pushing frame 311 and a first pushing driver 312 (the first pushing driver 312 can be a power source such as a motor or a cylinder), and the first pushing frame 311 is arranged opposite to the transfer frame 52; the stacking platform 3 is provided with an avoidance hole for the first pushing frame 311 to move back and forth to avoid interference; the first pushing driver 312 drives the first pushing frame 311 to push the napkins on the transfer frame 52 to the receiving tray 32 arranged in front of the stacking platform 3; the stacking platform 3 is provided with a horizontal guide rail 12, and the first pushing frame 311 is slidably arranged on the horizontal guide rail 12 through a horizontal slider 3111; so that the first pushing frame 311 can slide back and forth along the two ends of the discharge channel more smoothly;

[0044] The first material pushing driver 312 drives the first material pushing frame 311 to move back and forth through the transmission assembly 313, and the transmission assembly 313 includes a front articulated arm 3131 connected to the output shaft of the first material pushing driver 312, a rear articulated arm 3132 rotatably disposed on the horizontal slider 3111, and a linkage arm 3133;

[0045] One end of the linkage arm 3133 is hinged to the front articulated arm 3131, and the other end is hinged to the rear articulated arm 3132; the first pushing drive drives the front articulated arm 3131 to rotate, and the front articulated arm 3131 drives the rear articulated arm 3132 to rotate through the linkage arm 3133, and the rear articulated arm 3132 drives the horizontal slider 3111 to drive the first pushing rack 311 to slide along the horizontal guide rail 12, thereby realizing the transmission between the first pushing drive 312 and the first pushing rack 311.

[0046] In order to facilitate the reversal of the napkins, the lower end of the receiving tray is connected to a rotating cylinder 321 that drives the receiving tray 32 to rotate, so that the napkins pushed onto the receiving tray 32 can be reversed; because the cutting edges of the two stacks of napkins are opposite after the napkins are cut, one of the stacks of napkins needs to be reversed, that is, the receiving tray 32 is driven to rotate 180 degrees by the rotating cylinder 321 to achieve rapid and automatic reversal of one stack of napkins, so as to facilitate bagging of the napkins.

[0047] A discharge conveyor belt 7 is provided at the front end of the stacking frame 1, and a second pushing assembly 6 is provided on the stacking platform 3; the second pushing assembly 6 includes a second pushing driver 61 (the second pushing driver 61 can be a power source such as a motor or a cylinder) and a second pushing rack 62, and the second pushing rack 62 pushes the napkins on the receiving tray 32 to the discharge conveyor belt 7 under the drive of the second pushing driver 61; the discharge conveyor belt 7 transports the napkins to the packaging area for bagging; the second pushing driver 61 drives the second pushing rack 62 through a transmission belt and a transmission gear (existing transmission technology), so that the second pushing rack 62 can quickly feed back and forth between the discharge transmission belt and the receiving tray 32.

[0048] The stacking frame 1 is provided with two parallel feeding channels 2, wherein the two feeding channels 2 convey the napkins simultaneously; wherein a partitioning assembly 4 and a transfer assembly 5 are provided in front of each feeding channel 2, wherein the two partitioning assemblies 4 are driven by the same partitioning driver 41, and the partitioning driver 41 realizes synchronous driving of the two partitioning wheels 42 through a transmission belt;

[0049] The two transfer components 5 are driven by a unified transfer driver 51, wherein two transfer racks 52 are connected to a unified connecting shaft. The transfer driver 51 drives the connecting shaft to rotate, thereby driving the two transfer racks 52 to flip synchronously, thereby achieving synchronous separation and transfer of the napkins in the two feed channels 2, thereby improving production efficiency.

[0050] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
