[0054] like Figure 1 As shown, a paper rubbing system provided by an embodiment of the present invention includes a frame 100, a paper feeding device 200 and a paper rubbing device 300. The paper feeding device 200 is used to convey a paper group (composed of multiple cardboard skins stacked together) to the paper rubbing device 300. The paper rubbing device 300 can rub out the cardboard skins in the paper group one by one.

[0055] like Figure 2 As shown, the paper feeding device 200 includes a paper feeding mechanism 210 and a paper aligning mechanism 220. The paper feeding mechanism 210 is used to convey a paper group to the paper picking device 300. The paper aligning mechanism 220 can align the multiple carton skins in the paper group before the paper group is fed into the paper picking device 300, so that the multiple carton skins in the paper group are aligned, which is beneficial to the subsequent paper picking process.

[0056] Combine Figure 2 and Figure 3 The paper feeding mechanism 210 can carry a paper group and can drive the paper group to move along a first direction or a second direction opposite to the first direction.

[0057] Specifically, the paper set can be carried by the paper feed mechanism 210 and transported by the paper feed mechanism 210. It is understood that the paper feed mechanism 210 can transport the paper set in either a first direction or a second direction, wherein the first direction and the second direction are opposite directions and are both horizontal. Of course, in other embodiments, the first direction and the second direction can also be at a certain angle to the horizontal. Specifically, when the paper set on the paper feed mechanism 210 moves in the first direction, it gradually approaches the paper pickup device 300, and when it moves in the second direction, it gradually moves away from the paper pickup device 300.

[0058] like Figure 3 As shown, in some embodiments, the paper feeding mechanism 210 includes a paper feeding assembly 211 and a translation drive assembly 212 driven and connected to the paper feeding assembly 211. The paper feeding assembly 211 can carry a paper group and can drive the paper group to move along the first direction or the second direction. The translation drive assembly 212 can drive the paper feeding assembly 211 to move along the first direction or the second direction.

[0059] It can be understood that the paper feeding assembly 211 can carry a paper group and transport the paper group individually along the first direction or the second direction; the translation drive assembly 212 can drive the paper feeding assembly 211 to move along the first direction or the second direction, and make the paper group on the paper feeding assembly 211 move along the first direction or the second direction.

[0060] like Figure 4 As shown, in some embodiments, the translation drive assembly 212 includes a first drive member 2122, a main transmission wheel 2123 driven to rotate by the first drive member 2122, a slave transmission wheel 2124 spaced apart from the main transmission wheel 2123 along the first direction, and a conveyor belt 2125 sleeved on the main transmission wheel 2123 and the slave transmission wheel 2124; wherein, the paper feeding assembly 211 is connected to the conveyor belt 2125.

[0061] It is understood that the first driving member 2122 can drive the main transmission wheel 2123 to rotate, thereby driving the conveyor belt 2125 to move. When the conveyor belt 2125 is running, it drives the secondary transmission wheel 2124 to rotate. When the conveyor belt 2125 is running, it can also drive the paper feeding assembly 211 to move. Specifically, by controlling the first driving member 2122 to adjust the rotation direction of the main transmission wheel 2123, the movement direction of the paper feeding assembly 211 is changed, thereby achieving the purpose of moving the paper feeding assembly 211 in the first direction or the second direction.

[0062] Specifically, there are two main transmission wheels 2123, and the two main transmission wheels 2123 are arranged at intervals along the third direction. There are also two slave transmission wheels 2124, and the two slave transmission wheels 2124 are also arranged at intervals along the third direction. The main transmission wheels 2123 and the slave transmission wheels 2124 arranged at intervals and in parallel along the first direction form a group. In addition, the third direction is perpendicular to the first direction. There are also two conveyor belts 2125, one of which is connected to a group of main transmission wheels 2123 and slave transmission wheels 2124 arranged at intervals and in parallel along the first direction, and the other is connected to another group of main transmission wheels 2123 and slave transmission wheels 2124 arranged at intervals and in parallel along the first direction.

[0063] Furthermore, the first driving member 2122 is a motor, and the first driving member 2122 is connected to a driving shaft 2126, which passes through the two main transmission wheels 2123. The first driving member 2122 can drive the driving shaft 2126 to rotate, thereby driving the two main transmission wheels 2123 to rotate, thereby driving the two conveyor belts 2125 to run.

[0064] It should be noted that the translation drive assembly 212 further includes a first mounting frame 2121 , the first driving member 2122 is disposed on the first mounting frame 2121 , and the main transmission wheel 2123 and the slave transmission wheel 2124 are both rotatably disposed on the first mounting frame 2121 .

[0065] Combine Figure 4 and Figure 5 Furthermore, the first mounting frame 2121 is also provided with two main bearing seats for providing support for the two main transmission wheels 2123 respectively, and two slave bearing seats 21241 for providing support for the two slave transmission wheels 2124 respectively.

[0066] It should be noted that the main bearing seat is fixed to the first mounting frame 2121; the first connecting block 21242 is fixedly connected to the secondary bearing seat 21241, and the second connecting block 21243 is provided on the first mounting frame 2121. The secondary bearing seat 21241 can be fixed by means of bolts passing through the first connecting block 21242 and the second connecting block 21243.

[0067] like Figure 4 As shown, the first mounting frame 2121 further includes two first mounting side plates 21211 spaced apart and arranged side by side along the third direction, wherein a set of main transmission wheels 2123 and slave transmission wheels 2124 are rotatably mounted on one of the first mounting side plates 21211, and the other set of main transmission wheels 2123 and slave transmission wheels 2124 are rotatably mounted on the other first mounting side plate 21211. Furthermore, the first mounting frame 2121 further includes a cross-bracing shaft 21212 connected between the two mounting side plates, the cross-bracing shaft 21212 being used to hold the two first mounting side plates 21211 and strengthen the structure.

[0068] It should be noted that a guide rail 2127 is also provided on the first mounting frame 2121, and the guide rail 2127 extends along the first direction. A slider 2128 is provided on the guide rail 2127, wherein the paper feeding assembly 211 is connected to the conveyor belt 2125, and the paper feeding assembly 211 is also connected to the slider 2128. The cooperation between the slider 2128 and the guide rail 2127 can improve the movement accuracy of the paper feeding assembly 211.

[0069] Among them, the guide rail 2127 is located above the conveyor belt 2125 and is arranged parallel to the conveyor belt 2125. The upper part of the conveyor belt 2125 is connected to the first connecting plate 2129. The first connecting plate 2129 is U-shaped and semi-surrounds the guide rail 2127. The bottom of the paper feeding assembly 211 is connected to the first connecting plate 2129, and the bottom of the paper feeding assembly 211 is also connected to the slider 2128.

[0070] Combine Figure 3 and Figure 6In some embodiments, the paper feeding assembly 211 includes a second driving member 2112 and a plurality of conveying rollers 2113 driven by the second driving member 2112 to rotate synchronously, wherein the plurality of conveying rollers 2113 are arranged in parallel and at intervals along a first direction, and a paper group can be carried on the plurality of conveying rollers 2113. When the second driving member 2112 drives the plurality of conveying rollers 2113 to rotate simultaneously, it can drive the paper group to move along the first direction or the second direction.

[0071] It should be noted that the second driving member 2112 can simultaneously drive multiple conveying rollers 2113 to rotate forward or reverse. When the multiple conveying rollers 2113 rotate forward at the same time, the multiple conveying rollers 2113 can drive the paper group to move along the first direction. When the multiple conveying rollers 2113 reverse at the same time, the multiple conveying rollers 2113 can drive the paper group to move along the second direction.

[0072] Furthermore, the two / several conveying rollers 2113 located at the front and the back are rubber-coated conveying rollers, which have greater friction with the paper group and can more stably convey the paper group.

[0073] Combine Figure 6 and Figure 7 The paper feeding assembly 211 further includes a second mounting frame 2111 , a plurality of conveying rollers 2113 are rotatably disposed on the second mounting frame 2111 , and the second driving member 2112 simultaneously drives the plurality of conveying rollers 2113 to rotate through the transmission member 2114 .

[0074] Specifically, the second driving member 2112 is a motor, and the second driving member 2112 is connected to a driving sprocket 21121. One end of each conveying roller 2113 is rotatably connected to the second mounting frame 2111, and the other end is provided with a driven sprocket. The transmission component 2114 is a chain, which is wound around the driving sprocket 21121 and the driven sprockets on all the conveying rollers 2113. When the second driving member 2112 is working, it can drive the driving sprocket 21121 to rotate, thereby driving each conveying roller 2113 to rotate through the transmission component 2114.

[0075] A tensioning sprocket 2115 is further provided on the second mounting frame 2111 , and the chain is also wound around the tensioning sprocket 2115 .

[0076] It should be noted that the chain cooperates with the upper side of each driven sprocket, wherein a chain pressure plate 2116 is also provided on the second mounting frame 2111, and the chain pressure plate 2116 is used to limit the chain on the upper side of the driven sprocket on each conveying roller 2113 to prevent chain jumping.

[0077] Combine Figure 2 and Figure 8The paper aligning mechanism 220 includes a position switching component 221 and a paper aligning member 222 driven and connected to the position switching component 221. The position switching component 221 can drive the paper aligning member 222 to move to the paper blocking position, and can also drive the paper aligning member 222 to move to the avoidance position.

[0078] Specifically, when the paper aligner 222 is at the paper blocking position, the paper feeding mechanism 210 can drive the paper group to move along the second direction so that the paper group abuts against the paper aligner 222; when the paper aligner 222 is at the avoidance position, the paper aligner 222 avoids the moving path of the paper group.

[0079] It can be understood that when the paper group is carried by the paper feeding mechanism 210, under the action of the paper feeding mechanism 210, when moving along the first direction, it gradually approaches the paper picking device 300, and when moving along the second direction, it gradually moves away from the paper picking device 300. Therefore, before the paper group is delivered to the paper picking device 300, the position switching component 221 can first drive the paper aligning member 222 to move to the paper blocking position, and then the paper group can be transported along the second direction so that the paper group abuts the paper aligning member 222, which can achieve the effect of aligning multiple carton skins of the paper group. After the multiple carton skins are aligned, the paper group can be transported in the first direction again so that the paper group reaches the paper picking device 300.

[0080] It should be noted that the paper aligner 222 has an aligning panel, which is arranged perpendicular to the first direction. The aligning panel is used to abut against the paper group to align the multiple papers in the paper group.

[0081] like Figure 1 As shown, further, the paper feeding device 200 also includes a paper feeding mechanism 230, the conveying end of the paper feeding mechanism 230 is connected to the conveying head end of the paper feeding mechanism 210, and the paper feeding mechanism 230 can carry the paper group and drive the paper group to move along the first direction and be transferred by the paper feeding mechanism 210.

[0082] It is understandable that the paper set can be placed on the paper feeding mechanism 230 manually or automatically, and then the paper feeding mechanism 230 transports the paper set to the paper feeding mechanism 210 .

[0083] Specifically, the paper feed mechanism 230 can be a roller conveyor or a belt conveyor. The paper feed mechanism 230 and the paper feeding mechanism 210 are arranged sequentially along a first direction. The paper feed mechanism 230 can carry the paper set and drive the paper set to move along the first direction so that the paper set is transferred by the paper feeding mechanism 210. The conveying head end of the paper feeding assembly 211 is arranged opposite to the conveying end end of the paper feed mechanism 230. Driven by the translation drive assembly 212, the paper feed assembly 211 can move toward the conveying end end of the paper feed mechanism 230, so that the conveying head end of the paper feed assembly 211 is connected to the conveying end end of the paper feed mechanism 230.

[0084] Combine Figure 1 and Figure 2 Furthermore, the paper aligning mechanism 220 is arranged at the intersection of the paper feeding mechanism 230 and the paper feeding mechanism 210. When the paper aligning member 222 is in the paper blocking position, the paper aligning member 222 can also prevent the paper group on the paper feeding mechanism 230 from being transported to the paper feeding mechanism 210; when the paper aligning member 222 is in the avoidance position, the paper aligning member 222 does not prevent the paper group on the paper feeding mechanism 230 from being transported to the paper feeding mechanism 210.

[0085] It can be understood that when the paper feeding device 200 of the present invention is in use, first, the paper aligner 222 moves to the avoidance position under the action of the position switching component 221. At this time, the paper group on the paper feeding mechanism 230 can be conveyed to the paper feeding mechanism 210, and then the paper feeding mechanism 210 conveys the paper group along the first direction so that the paper group passes the intersection position between the paper feeding mechanism 230 and the paper feeding mechanism 210. After that, the position switching component 221 moves the paper aligner 222 to the paper blocking position. After that, the paper feeding mechanism 210 conveys the paper group along the second direction so that the paper group rests on the paper aligner 222, thereby aligning the multiple carton skins in the paper group. After that, the paper feeding mechanism 210 conveys the paper group along the first direction so that the paper group reaches the paper picking device 300.

[0086] Specifically, first, the paper aligner 222 moves to the avoidance position under the action of the position switching component 221. At this time (the conveying head end of the paper feeding component 211 and the conveying end end of the paper feeding mechanism 230 are in a docking state), the paper group on the paper feeding mechanism 230 can be conveyed to the paper feeding component 211. As long as part of the paper group contacts the paper feeding component 211 (the paper group is in the feeding position at this time), the paper feeding mechanism 230 can stop conveying. Subsequently, the paper feeding component 211 drives the paper group to move in the first direction, so that the entire paper group is carried by the paper feeding component 211 and is located in the first waiting position (at this time, the paper group passes the intersection of the paper feeding mechanism 230 and the paper feeding mechanism 210). The paper feeding component 211 stops running. Thereafter , the position switching component 221 moves the paper aligning member 222 to the paper blocking position, and then the paper feeding component 211 conveys the paper group along the second direction so that the paper group rests on the paper aligning member 222 (at this time the paper group is in the paper alignment position), thereby aligning the multiple carton skins in the paper group, and then the paper feeding component 211 conveys the paper group along the first direction until the paper group is in the second waiting position, and then, when the paper picking device 300 needs to pick up the paper, the translation drive component 212 drives the paper feeding component 211 to move along the first direction again, so that the paper group gradually approaches the paper picking device 300, and then, the paper feeding component 211 drives the paper group to move along the first direction again, so that the paper group approaches the paper picking device 300 and is transferred by the paper picking device 300.

[0087] It should be noted that the paper feeding assembly 211 is provided with a first position sensor and a second position sensor. The first position sensor is used to detect whether the paper group has reached the feeding position, and the second position sensor is used to detect whether the paper group has reached the first waiting position. In addition, taking the paper feeding assembly 211 as a reference system, when the paper group is in the first waiting position and the second waiting position, the relative position of the paper group and the paper feeding assembly 211 is the same, and the second position sensor can also be used to detect whether the paper group has reached the second waiting position.

[0088] The first position sensor is located near the conveying head end of the paper feeding assembly 211 (close to the paper feeding mechanism 230 ), and the second position sensor is located near the conveying end end of the paper feeding assembly 211 (far away from the paper feeding mechanism 230 ).

[0089] Combine Figure 2 and Figure 8 As shown, in some embodiments, the paper feeding device 200 is arranged on the frame 100, wherein the position switching component 221 is arranged on the frame 100 and avoids the conveying path of the paper group, and the position switching component 221 is used to drive the paper aligner 222 to move to the paper blocking position or the avoidance position.

[0090] Specifically, the position switching component 221 is arranged above the paper feeding mechanism 210, and there is a space for the paper group to pass between the position switching component 221 and the paper feeding mechanism 210. The paper aligner 222 is located below the position switching component 221. The position switching component 221 can drive the paper aligner 222 to rise and fall, so that the paper aligner 222 moves to the paper blocking position or the avoidance position.

[0091] More specifically, the position switching component 221 is arranged above the paper feeding component 211, and there is a space for the paper group to pass between the position switching component 221 and the paper feeding component 211. The paper aligner 222 is located below the position switching component 221. The position switching component 221 can drive the paper aligner 222 to rise and fall, so that the paper aligner 222 moves to the paper blocking position or the avoidance position.

[0092] Furthermore, a vertical guide member 223 is provided on the frame 100 , and a vertical guide groove is provided on the vertical guide member 223 . The side of the paper aligner 222 is inserted into the vertical guide groove. The vertical guide member 223 can guide the lifting and lowering movement of the paper aligner 222 .

[0093] Furthermore, the position switching assembly 221 includes a protective frame 2211, a third driving member 2212 arranged on the protective frame 2211, a first cable 2213 connected to the third driving member 2212, and a second cable 2214 connected to the third driving member 2212. The first cable 2213 and the second cable 2214 are respectively connected to the tops of the two ends of the paper aligning member 222 along the third direction. The third driving member 2212 can simultaneously drive the first cable 2213 and the second cable 2214 to rise and fall, thereby driving the paper aligning member 222 to rise and fall.

[0094] Specifically, the third driving member 2212 is a telescopic driving member, which can be a cylinder or a hydraulic cylinder. The telescopic shaft of the third driving member 2212 is connected to the first cable 2213 and the second cable 2214; the position switching assembly 221 also includes an idler group, one end of the first cable 2213 is connected to the telescopic shaft of the third driving member 2212, the first cable 2213 bypasses at least part of the idler in the idler group and is connected to the top of one end of the paper tidying member 222, one end of the first cable 2213 is connected to the telescopic shaft of the third driving member 2212, the second cable 2214 bypasses at least part of the idler in the idler group and is connected to the top of the other end of the paper tidying member 222.

[0095] Combine Figure 8 and Figure 9 , wherein the idler wheel group includes a first idler wheel 2216 and a second idler wheel 2217 arranged along the first direction, a third idler wheel 2218 and a fourth idler wheel 2219 arranged along the third direction with the second idler wheel 2217, one end of the first cable 2213 is connected to the telescopic shaft of the third driving member 2212, and the first cable 2213 bypasses the first idler wheel 2216 and is connected to the top of one end of the paper aligning member 222, one end of the second cable 2214 is connected to the telescopic shaft of the third driving member 2212, the second cable 2214 bypasses the second idler wheel 2217, the third idler wheel 2218 and the fourth idler wheel 2219 and is connected to the top of the other end of the paper aligning member 222.

[0096] It should be noted that the telescopic shaft of the third driving member 2212 is also provided with a first adjusting screw and a second adjusting screw 2215 that can be adjusted axially. The first cable 2213 is connected to the first adjusting screw, and the second cable 2214 is connected to the second adjusting screw 2215. By adjusting the axial position of the first adjusting screw and the second adjusting screw 2215 relative to the telescopic shaft of the third driving member 2212, the tightness of the first cable 2213 and the second cable 2214 can be made consistent, so that the paper tidying member 222 can be raised and lowered without tilting.

[0097] like Figure 10As shown, the paper feeding device 200 is used to convey the paper group to the paper picking device 300, and the paper picking device 300 can pick out the carton skins of the paper group one by one. Wherein, the paper picking device 300 is arranged on the frame.

[0098] like Figure 11 As shown, the paper picking device 300 includes a paper picking mechanism 310 and a first paper stopping mechanism 320. A paper picking gap is formed between the paper picking mechanism 310 and the first paper stopping mechanism 320. The paper picking mechanism 310 can carry the paper group and drive the paper group to move along the first direction, so that multiple carton skins on the paper group are picked out one by one from bottom to top through the paper picking gap.

[0099] It is understandable that the paper feeding device 200 can feed the paper set to the paper pickup mechanism 310 .

[0100] like Figure 12 As shown, the paper pickup mechanism 310 includes a paper pickup drive component 311 and a paper pickup component 312 , and the paper pickup drive component 311 is drivingly connected to the paper pickup component 312 .

[0101] Combine Figure 13 and Figure 14 The paper pickup assembly 312 includes a third mounting frame 3121 , two transmission wheels 3122 and a paper pickup belt 3123 .

[0102] The two transmission wheels 3122 are spaced apart and arranged on the third mounting frame 3121 along the first direction.

[0103] Specifically, the two transmission wheels 3122 are arranged side by side and spaced apart along the first direction, and the axes of the two transmission wheels 3122 are parallel to each other. Each transmission wheel 3122 can rotate relative to the third mounting frame 3121, and each transmission wheel 3122 can rotate around its own axis.

[0104] Among them, the third mounting frame 3121 includes a mounting block 31211 and two second mounting side plates 31212 spaced apart and arranged in parallel on both sides of the mounting block 31211 along the third direction, and the two transmission wheels 3122 are both arranged between the two second mounting side plates 31212 and spaced apart along the first direction.

[0105] Furthermore, the third mounting frame 3121 also includes a mounting shaft 31213 connected between the two second mounting side plates 31212 . The two mounting shafts 31213 are arranged in parallel and at intervals along the first direction, and the two transmission wheels 3122 are rotatably mounted on the two mounting shafts 31213 .

[0106] It should be noted that one of the transmission wheels 3122 is defined as the driving wheel 31221, and the other transmission wheel 3122 is defined as the driven wheel 31222, one of the mounting shafts 31213 is defined as the first mounting shaft 312131, and the other mounting shaft 31213 is defined as the second mounting shaft 312132, the driving wheel 31221 is rotatably mounted on the first mounting shaft 312131, and the driven wheel 31222 is rotatably mounted on the second mounting shaft 312132.

[0107] The pickup belt 3123 is sleeved outside the two transmission wheels 3122 .

[0108] Specifically, both ends of the pickup belt 3123 are respectively sleeved on the two transmission wheels 3122, and the pickup belt 3123 and the two transmission wheels 3122 are engaged with each other. When the driving wheel 31221 rotates, the pickup belt 3123 can run, and when the pickup belt 3123 runs, it drives the driven wheel 31222 to rotate.

[0109] The pickup drive assembly 311 is drivably connected to the driving wheel 31221, and the pickup drive assembly 311 is used to drive the driving wheel 31221 to rotate, thereby causing the pickup belt 3123 to operate. It is understood that the paper feeding device 200 can feed the paper set to the pickup belt 3123, and the pickup belt 3123 can carry the paper set and drive the paper set to move along the first direction during operation.

[0110] Furthermore, the outer side of the paper rubbing belt 3123 can be coated with glue to increase the friction between the belt and the carton skin, making it easier to rub the paper.

[0111] Combine Figure 13 and Figure 14 The paper pickup assembly 312 also includes a tensioning unit 3124, which includes a bracket 31241 rotatably connected to the third mounting bracket 3121, and a tensioning wheel 31242 connected to the bracket 31241, and the tensioning wheel 31242 is abutted against the inner wall of the paper pickup belt 3123; wherein the bracket 31241 is configured to be rotatable so that the position of the tensioning wheel 31242 can be adjusted to change the tightness of the paper pickup belt 3123.

[0112] It is understood that the tensioning wheel 31242 abuts against the inner wall of the pickup belt 3123, thereby keeping the pickup belt 3123 taut and improving the transport efficiency. Of course, by rotating the bracket 31241, the position of the tensioning wheel 31242 can be adjusted, thereby changing the tightness of the pickup belt 3123. Furthermore, the position of the tensioning wheel 31242 can be adjusted to accommodate pickup belts 3123 of different lengths, ensuring that the tightness of the pickup belt 3123 remains within an appropriate range.

[0113] Combine Figure 13 and Figure 14In some embodiments, the paper pickup assembly 312 further includes a first support member 3125 connected to the third mounting bracket 3121 and located in a space formed by the paper pickup belt 3123, and a supporting member 3126 provided on the first support member 3125, wherein the supporting member 3126 is in contact with the bracket 31241 so that the tensioning wheel 31242 is in contact with the inner wall of the paper pickup belt 3123.

[0114] Specifically, the pickup belt 3123 is a closed structure connected end to end. A first support member 3125 is disposed within the enclosed interior space. The first support member 3125 is also connected to two second mounting side panels 31212, which serve to enhance the strength of the third mounting bracket 3121. A supporting member 3126 is disposed on the first support member 3125 and is configured to abut against the bracket 31241, thereby enabling the bracket 31241 to exert a force on the tensioning wheel 31242, causing the tensioning wheel 31242 to abut against the inner wall of the pickup belt 3123, thereby maintaining a taut state for the pickup belt 3123.

[0115] Specifically, one end of the bracket 31241 is rotatably connected to the third mounting frame 3121 , and the other end is connected to the tensioning wheel 31242 .

[0116] like Figure 14 As shown, in one embodiment, the resisting member 3126 is threadedly connected to the first supporting member 3125 , and the resisting member 3126 can be operated to drive the bracket 31241 to rotate to change the tightness between the tensioning wheel 31242 and the paper pickup belt 3123 .

[0117] It can be understood that the supporting member 3126 can be a screw, which is threadedly connected to the first support member 3125. By rotating the supporting member 3126, the position of the supporting member 3126 can be changed. Since the supporting member 3126 supports the bracket 31241, the angle of the bracket 31241 will be adjusted after the position of the supporting member 3126 is changed, thereby changing the tightness between the tensioning wheel 31242 and the paper pickup belt 3123.

[0118] Specifically, one end of the bracket 31241 is rotatably connected to the second mounting shaft 312132, and the other end of the bracket 31241 is connected to the tensioning wheel 31242, and the tensioning wheel 31242 is used to abut against the inner wall of the lower side of the paper pickup belt 3123; the abutting member 3126 is threadedly connected to the first support member 3125, and rotating the abutting member 3126 can make the abutting member 3126 rise and fall. After the abutting member 3126 rises, the force between the tensioning wheel 31242 and the paper pickup belt 3123 decreases. After the abutting member 3126 falls, the force between the tensioning wheel 31242 and the paper pickup belt 3123 increases.

[0119] It should be noted that after the position adjustment of the tensioning wheel 31242 is completed, the end of the bracket 31241 away from the tensioning wheel 31242 can be locked to the second mounting shaft 312132 with the help of other screws to further improve the stability of the bracket 31241.

[0120] In other embodiments, the supporting member 3126 is a telescopic member, such as an electric push rod, which can drive the bracket 31241 to rotate to change the tightness between the tensioning wheel 31242 and the paper pickup belt 3123.

[0121] like Figure 14 As shown, further, the tensioning wheel 31242 is rotatably connected to the bracket 31241, and the tensioning wheel 31242 is rollingly engaged with the inner wall of the paper pickup belt 3123.

[0122] It is understandable that the tensioning wheel 31242 can rotate relative to the bracket 31241. When the paper pickup belt 3123 is running, the paper pickup belt 3123 drives the tensioning wheel 31242 to roll, which helps to reduce the friction between the tensioning wheel 31242 and the paper pickup belt 3123 and reduce wear.

[0123] Combine Figure 14 and Figure 15 In some embodiments, the paper pickup assembly 312 also includes a first gear 3128 coaxially arranged and connected to the driving wheel 31221; the paper pickup drive assembly 311 includes a fourth driving member 3111, a transmission shaft 3112 drivingly connected to the fourth driving member 3111, and a second gear 3113 sleeved on the transmission shaft 3112, and the second gear 3113 is engaged with the first gear 3128.

[0124] It can be understood that the fourth driving member 3111 is used to drive the transmission shaft 3112 to rotate around the axis of the transmission shaft 3112, thereby driving the second gear 3113 to rotate, and the second gear 3113 can drive the first gear 3128 to rotate, thereby driving the driving wheel 31221 to rotate, thereby realizing the operation of the paper pickup belt 3123.

[0125] Specifically, the first gear 3128 is coaxially arranged and fixedly connected to the driving wheel 31221, the second gear 3113 is sleeved on the transmission shaft 3112 and can rotate with the transmission shaft 3112, and the fourth driving member 3111 is a motor for driving the transmission shaft 3112 to rotate.

[0126] like Figure 15 As shown, in some embodiments, the paper pickup drive assembly 311 further includes a support bearing assembly 3114 sleeved on the middle portion of the transmission shaft 3112 .

[0127] It can be understood that the support bearing assembly 3114 is used to support the middle portion of the transmission shaft 3112, thereby reducing the degree of bending of the transmission shaft 3112.

[0128] Specifically, the support bearing assembly 3114 includes a support bearing 31141 sleeved on the middle portion of the transmission shaft 3112 and a support 31142 supporting the support bearing 31141 , wherein the support 31142 is disposed on the frame 100 .

[0129] like Figure 16 As shown, the first paper stopper mechanism 320 includes a first paper stopper assembly 321 disposed opposite the paper pickup mechanism 310. A paper pickup gap is formed between the first paper stopper assembly 321 and the paper pickup mechanism 310. The paper pickup mechanism 310 is configured to carry the paper stack and move the paper stack in a first direction to pass through the paper pickup gap. Specifically, a paper pickup gap is formed between the first paper stopper assembly 321 and the paper pickup belt 3123. The paper pickup belt 3123 is configured to carry the paper stack and move the paper stack in the first direction, thereby pulling multiple carton wrappers from the paper stack upward through the paper pickup gap one by one.

[0130] It is understood that the distance between the first paper stop assembly 321 and the paper pickup belt 3123, i.e., the width of the paper pickup gap, is greater than the thickness of one carton skin and less than the thickness of two carton skins. When a stack of carton skins is being transported by the paper pickup belt 3123, the carton skin at the bottom can pass through the paper pickup gap. In this way, the carton skins can be pulled out one by one under the action of the paper pickup mechanism 310.

[0131] Combine Figure 17 and Figure 19 Furthermore, the first paper stopper assembly 321 includes a first paper stopper 3211 and a paper pressing member 3212 sequentially arranged along the first direction.

[0132] It is understood that the distance between the first paper stopper 3211 and the paper rubbing belt 3123 is greater than the thickness of one carton skin and less than the thickness of two carton skins, and the distance between the paper pressing member 3212 and the paper rubbing belt 3123 is also greater than the thickness of one carton skin and less than the thickness of two carton skins. When the paper group is being transported by the paper rubbing belt 3123, due to the blocking effect of the first paper stopper 3211, only the carton skin at the bottom enters the gap between the first paper stopper 3211 and the paper rubbing belt 3123 under the transportation action of the paper rubbing mechanism 310. As the bottom carton skin continues to be transported, the carton skin enters the gap between the paper pressing member 3212 and the paper rubbing belt 3123. The paper pressing member 3212 acts as a limiter for the carton skin, which can alleviate the problem of the carton skin jumping during transportation and help the carton skin enter the subsequent process in a more stable posture.

[0133] Furthermore, the side of the paper pressing member 3212 close to the paper picking gap is a paper pressing plane 32121. The paper pressing plane 32121 is parallel to the carton skin entering the paper picking gap, and the contact area between the paper pressing plane 32121 and the carton skin is large, which is conducive to suppressing the carton skin from jumping during transportation.

[0134] like Figure 14 As shown, in some embodiments, the paper pickup assembly 312 further includes a pad 3127 connected to the third mounting bracket 3121 , wherein the pad 3127 can be connected to the second mounting side plate 31212 or be disposed on the first support member 3125 .

[0135] Combine Figure 14 and Figure 16 Furthermore, the paper pickup belt 3123 has a paper pickup portion 31231 arranged opposite to the first paper blocking assembly 321, and the pad 3127 is supported on the paper pickup portion 31231 to make the paper pickup portion 31231 flat.

[0136] It can be understood that when the paper group is being transported by the paper rubbing belt 3123, the carton skin at the bottom can pass through the gap between the first paper stop 3211 and the paper rubbing part 31231. In this way, under the action of the paper rubbing assembly 312, the carton skins can be rubbed out one by one. By using the pad 3127 to support the paper rubbing part 31231, the paper rubbing part 31231 becomes flatter, which is conducive to paper rubbing.

[0137] Combine Figure 18 and Figure 19 In some embodiments, the first paper stop mechanism 320 further includes a gap adjustment component 322 that is transmission-connected to the first paper stop component 321. The gap adjustment component 322 can operably adjust the distance between the first paper stop component 321 and the paper picking mechanism 310 to adjust the width of the paper picking gap.

[0138] It is understandable that, according to the thickness of the carton skin, the distance between the first paper stop assembly 321 and the paper picking mechanism 310 can be adjusted, thereby adjusting the width of the paper picking gap to adapt to carton skins of different thicknesses.

[0139] Combine Figure 18 and Figure 19The first adjusting rod 3222 is arranged perpendicular to the second adjusting rod 3223, and the first adjusting rod 3223 is arranged perpendicular to the second adjusting rod 3223. The first adjusting rod 3222 is threadably connected to the first paper stopper assembly 321. The axial direction of the adjusting screw 3224 is parallel to the width direction of the paper-rubbing gap. The end of the adjusting screw 3224 away from the paper-rubbing gap is provided with a first bevel gear, and the axial direction of the second adjusting rod 3223 is parallel to the first direction. The second adjusting rod 3223 is sleeved with a second bevel gear meshing with the first bevel gear, and a third bevel gear is sleeved with the second bevel gear along the axial direction of the second adjusting rod 3223. The first adjusting rod 3222 is arranged perpendicular to the second adjusting rod 3223, and the first adjusting rod 3222 is sleeved with a fourth bevel gear meshing with the third bevel gear.

[0140] Rotating the first adjusting rod 3222 can drive the second adjusting rod 3223 to rotate, thereby driving the adjusting screw rod 3224 to rotate, thereby driving the first paper stop assembly 321 to move axially along the adjusting screw rod 3224, thereby adjusting the distance between the first paper stop assembly 321 and the paper pickup mechanism 310.

[0141] It should be noted that the gap adjustment assembly 322 also includes a second support member 3221 disposed on the frame 100. The second support member 3221 is provided with a first bearing seat 3225 and a second bearing seat 3226. The first adjustment rod 3222 is disposed through the first bearing seat 3225, which is used to support the first adjustment rod 3222. The second adjustment rod 3223 is disposed through the second bearing seat 3226, which is used to support the second adjustment rod 3223. The second support member 3221 is fixed to the frame 100.

[0142] It should be noted that the first paper stop assembly 321 is restricted from rotating along with the adjusting screw 3224 by a limiting structure. When the adjusting screw 3224 rotates, it can only drive the first paper stop assembly 321 to move axially along the adjusting screw 3224, wherein the limiting structure can be a guide rail.

[0143] like Figure 19As shown, the first paper stopper 3211 is integrally connected to a third connecting block 3214, and the paper pressing member 3212 is connected to the third connecting block 3214. The third connecting block 3214 may be provided with a strip-shaped hole, the length of which is parallel to the width of the pickup gap. The paper pressing member 3212 is secured to the connecting block with bolts. The strip-shaped hole allows the position of the paper pressing member 3212 to be adjusted, thereby adjusting the gap between the paper pressing block and the pickup belt 3123. Furthermore, the third connecting block 3214 is connected to the first connecting portion 3215, which is connected to the second connecting portion 3216. The second connecting portion 3216 is screwed to a mounting plate 3217, wherein the mounting plate 3217 is secured to the frame 100.

[0144] The first paper stop assembly 321 further includes a second connecting plate 3213 connected to the third connecting block 3214 , and the second connecting plate 3213 is provided with a screw hole for the adjusting screw rod 3224 to pass through.

[0145] Combine Figure 16 and Figure 17 It should be noted that the first paper stopper mechanism 320 further includes a paper stopper 323. The paper stopper 323 and the first paper stopper assembly 321 are arranged sequentially along the first direction. The end of the paper stopper 323 closer to the paper pickup mechanism 310 is farther from the paper pickup mechanism 310 than the end of the first paper stopper assembly 321 closer to the paper pickup mechanism 310. Specifically, the end of the paper stopper 323 closer to the paper pickup belt 3123 is farther from the paper pickup mechanism 310 than the end of the first paper stopper assembly 321 closer to the paper pickup belt 3123. The paper stopper 323 can limit the position of the paper group placed on the paper pickup assembly 312.

[0146] It can be understood that after being aligned, the paper group can be transported along the first direction by the paper feeding mechanism 210, so that it leans against the paper stop 323. The paper stop 323 is used to limit the paper group. When the paper group is against the paper stop 323, the paper group as a whole is located above the paper pickup mechanism 310 (paper pickup belt 3123).

[0147] It should be noted that if Figure 18 As described above, the paper retaining plate 323 is connected to the first connecting frame 324 , and the first connecting frame 324 is fixed to the frame 100 .

[0148] like Figure 11 As shown, in some embodiments, the paper picking device 300 further includes a second paper stopping mechanism 330 , and the second paper stopping mechanism 330 and the first paper stopping mechanism 320 are sequentially and spaced apart along the first direction.

[0149] It is understood that the paper set can be confined between the first paper stopper 320 and the second paper stopper 330. Specifically, after the paper set is aligned, it can be transported by the paper feed mechanism 210 in a first direction so that it rests on the paper stopper 323. Thereafter, the translation drive assembly 212 drives the paper feed assembly 211 to move in a second direction, so that the paper set can fall along the paper stopper 323 and the second paper stopper 330 onto the paper pickup mechanism 310.

[0150] More specifically, after the paper group is aligned, the translation drive assembly 212 drives the paper feeding assembly 211 to move along the first direction until the paper feeding assembly 211 is in the paper feeding position. At this time, the paper feeding assembly 211 is basically located above the paper picking mechanism 310; then, the paper feeding assembly 211 transports the paper group along the first direction again until the paper group hits the first paper stop 323 of the first paper stop mechanism 320. Thereafter, the paper feeding assembly 211 continues to operate, and the translation drive assembly 212 drives the paper feeding assembly 211 to move along the second direction until the paper feeding assembly 211 moves to the third waiting position. The translation drive assembly 212 stops driving the paper feeding assembly 211, and the paper feeding assembly 211 also stops providing driving force to the paper group. During this process, the paper group will fall onto the paper picking mechanism 310. When the paper group falls, the paper group will stick to the paper stop 323 and the second paper stop mechanism 330 to ensure the positioning accuracy after falling.

[0151] It should be noted that the translation drive assembly 212 is provided with a third position sensor and a fourth position sensor. The third position sensor is used to detect whether the paper feeding assembly 211 reaches the paper feeding position, and the fourth position sensor is used to detect whether the paper feeding assembly 211 reaches the third waiting position.

[0152] Specifically, the third position sensor is disposed at an end of the translation drive assembly 212 close to the first paper blocking mechanism 320 , and the fourth position sensor is disposed at an end of the first paper blocking mechanism 320 away from the first paper blocking mechanism 320 .

[0153] Combine Figure 10 and Figure 20 Furthermore, the second paper stopper mechanism 330 includes a distance adjustment assembly 331 and a second paper stopper assembly 332 in transmission connection with the distance adjustment assembly 331. The second paper stopper assembly 332 and the first paper stopper assembly 321 are arranged sequentially and spaced apart along the first direction. The distance adjustment assembly 331 is operable to adjust the distance between the second paper stopper assembly 332 and the first paper stopper assembly 321. This allows for positioning of cartons of different sizes.

[0154] like Figures 20 to 22As shown, specifically, the distance adjustment assembly 331 includes a fifth driving member 3311 and a distance adjustment screw rod 3312 drivingly connected to the fifth driving member 3311 , and the second paper blocking assembly 332 is threadedly connected to the distance adjustment screw rod 3312 .

[0155] Among them, the fifth driving member 3311 can be a motor, which is used to drive the distance adjustment screw 3312 to rotate. The axial direction of the distance adjustment screw 3312 is parallel to the first direction. When the distance adjustment screw 3312 rotates, it drives the second paper stop assembly 332 to approach or move away from the first paper stop assembly 321.

[0156] Among them, the distance adjustment component 331 also includes a guide shaft 3313 extending along the first direction. The guide shaft 3313 is passed through the second paper stop component 332. The guide shaft 3313 guides the second paper stop component 332 and can also limit the second paper stop component 332 from being driven to rotate by the distance adjustment screw 3312.

[0157] Both ends of the guide shaft 3313 are connected to the second connecting frames 333 , and the second connecting frames 333 are arranged on the frame 100 . Both ends of the distance adjustment screw rod 3312 are also respectively arranged on the two second connecting frames 333 through bearings.

[0158] In some embodiments, the second paper stopper assembly 332 includes a connecting frame 3321 and a second paper stopper 3322 disposed on the connecting frame 3321. The distance adjustment assembly 331 is connected to the connecting frame 3321.

[0159] Specifically, the connection frame 3321 is provided with a threaded sleeve 33212 for the distance adjustment screw rod 3312 to pass through, and a through hole for the guide shaft 3313 to pass through.

[0160] Furthermore, the number of the second paper stops 3322 can be set to multiple, and the multiple second paper stops 3322 are arranged at intervals along the third direction, and the distance between two adjacent second paper stops 3322 is adjustable, so that it can adapt to carton shells of various sizes.

[0161] Among them, the second paper stop assembly 332 also includes an adjusting tube 3323 arranged on the connecting frame 3321, and the second paper stop 3322 is arranged on the adjusting tube 3323 through the connecting hoop 3324, and the connecting hoop 3324 is locked by a locking bolt. When the locking bolt is removed, the position of the second paper stop 3322 can be adjusted.

[0162] It should be noted that the second paper stopper 3322 can also support the carton skin, so that the carton skin is at a certain angle (the end of the carton skin close to the paper rubbing gap is lower than the end of the carton skin away from the paper rubbing gap), which is conducive to passing through the paper rubbing gap.

[0163] like Figure 16 As shown, in some embodiments, the paper picking device 300 further includes a paper support mechanism 340 , which is disposed between the second paper stop assembly 332 and the first paper stop assembly 321 , and the top of the paper support mechanism 340 is higher than the top of the paper picking gap.

[0164] It can be understood that the paper support mechanism 340 can support the carton skin. On the one hand, it can reduce the risk of the carton skin collapsing due to its softness. On the other hand, it can also make the front end of the carton skin tilt downward, making it easier for the carton skin to be rubbed out through the paper rubbing gap.

[0165] Combine Figure 16 and Figure 23 Specifically, the paper support mechanism 340 includes a clamping block 342 and a support rod 341 provided on the clamping block 342. A connecting screw 343 is provided below the clamping block 342, and the connecting screw 343 is threadedly connected to the third mounting bracket 3121.

[0166] like Figure 24 As shown, in some embodiments, the paper picking device 300 also includes a side paper stop mechanism 350, which is used to limit the left and right sides of the carton skin located on the paper picking mechanism 310. In this way, under the joint action of the first paper stop mechanism 320, the second paper stop mechanism 330 and the side paper stop mechanism 350, the carton skin can be limited in all directions.

[0167] like Figure 25 As shown, the side paper stop mechanism 350 includes two side paper stop assemblies 351 that are spaced apart and arranged opposite to each other. The spacing direction of the two side paper stop assemblies 351 is the third direction, and the two side paper stop assemblies 351 can limit the left and right sides of the carton skin respectively.

[0168] Furthermore, the distance between the two side paper stop assemblies 351 is adjustable, so as to adapt to carton skins of different sizes.

[0169] Specifically, the side paper stop mechanism 350 also includes two width adjustment screw rods 352 extending along the third direction, defining one side paper stop assembly 351 as a left paper stop assembly, and the other side paper stop assembly 351 as a right paper stop assembly, one width adjustment screw rod 352 as a first width adjustment screw rod, and the other width adjustment screw rod 352 as a second width adjustment screw rod, wherein the left half of the first width adjustment screw rod is a threaded section, and the right half is a smooth section, and the left half of the second width adjustment screw rod is a smooth section, and the right half is a threaded section, wherein both side paper stop assemblies 351 are passed through by the two width adjustment screw rods 352, and the left paper stop assembly is threadedly connected to the threaded section of the first width adjustment screw rod, the left paper stop assembly is slidingly matched with the smooth section of the second width adjustment screw rod, the right paper stop assembly is threadedly connected to the threaded section of the second width adjustment screw rod, and the right paper stop assembly is slidingly matched with the smooth section of the first width adjustment screw rod.

[0170] It can be understood that by rotating the first width adjustment screw rod, the left paper stop assembly can be moved, and by rotating the second width adjustment screw rod, the right paper stop assembly can be moved. The two side paper stop assemblies 351 can be adjusted separately.

[0171] Specifically, a threaded sleeve and a sliding sleeve are provided on the left paper stop assembly and the right paper stop assembly, wherein the threaded sleeve on the left paper stop assembly is for the threaded section of the first width adjustment screw rod to pass through, and the sliding sleeve on the left paper stop assembly is for the smooth section of the second width adjustment screw rod to pass through, the threaded sleeve on the right paper stop assembly is for the threaded section of the second width adjustment screw rod to pass through, and the sliding sleeve on the right paper stop assembly is for the smooth section of the first width adjustment screw rod to pass through.

[0172] Furthermore, hand wheels are provided on the two width-adjusting screw rods 352 to facilitate operators to rotate the width-adjusting screw rods 352 .

[0173] In some embodiments, the side stop mechanism 350 further includes two side stop mounting brackets 356 and two side stop mounting blocks 357, respectively mounted on the two side stop mounting brackets 356. Both ends of the two width adjustment screw rods 352 are mounted on the two side stop mounting blocks 357 via bearings, allowing both width adjustment screw rods 352 to rotate. The side stop mounting brackets 356 are fixed to the frame 100.

[0174] Furthermore, the side paper stop mechanism 350 also includes a first screw middle support bracket 353 and a second screw middle support bracket 354. The first screw middle support bracket 353 is screwed to the frame 100, and the second screw middle support bracket 354 is fixed to the first screw middle support bracket 353. The second screw middle support bracket 354 is fixedly connected to a screw middle support block 355. The screw middle support block 355 is provided with two bearings for two width adjustment screws 352 to pass through respectively. The screw middle support block 355 is used to support the middle part of the width adjustment screw 352.

[0175] Furthermore, the side paper stop assembly 351 includes a side stop mounting block 3511 and a side stop 3512 connected to the side stop mounting block 3511. The side stop mounting block 3511 is mounted on the width adjustment screw rod 352, and the side stop mounting block 3511 is used for allowing two width adjustment screw rods 352 to pass through.

[0176] Furthermore, a side baffle auxiliary support member 3513 is provided on the side baffle 3512 . The side baffle auxiliary support member 3513 can be supported by the support rod 341 , and the support rod 341 can assist in supporting the side baffle 3512 .

[0177] Combine Figure 26 and Figure 27 In some embodiments, the paper picking system also includes a pressure roller device 400 arranged on the frame 100, and the pressure roller device 400 includes a pressure roller bracket 410, a pressure roller connecting rod 420, a pressure roller swing arm 430, a counterweight 440, a handle 450 and a pressure roller group 460; the pressure roller bracket 410 is arranged on the frame 100; the pressure roller connecting rod 420 is fixed to the pressure roller bracket 410 and can adjust the locking position along the first direction; one end of the pressure roller swing arm 430 is rotatably connected to the pressure roller connecting rod 420, and the pressure roller swing arm 430 can swing; the counterweight 440 is fixedly installed on the pressure roller swing arm 430, and the installation position of the counterweight 440 can be adjusted up and down to provide paper pressing force; the handle 450 is axially connected to the paper roller swing arm, the handle 450 is rotatable, and a handle is installed at one end of the handle; the pressure roller group 460 is installed on the pressure roller swing arm 430 and can rotate.

[0178] It can be understood that: the paper pressing wheel device 400 provides passive paper pressing pressure; when the carton skin is transported from the conveying plane of the paper picking device 300 to the top of the roller 500 at the paper feeding entrance of the climbing belt of the wrapping machine main body, the paper pressing wheel group 460 contacts the roller 500 and is lifted up by the carton skin. The paper pressing wheel group 460 contacts the top of the carton skin and provides a certain pressure to prevent the carton skin from moving or jumping; among them, by adjusting the locking position of the paper pressing wheel connecting rod 420 along the first direction, it can be ensured that the paper pressing wheel group 460 is aligned with the roller 500; the operator can lift the handle 450 shaft for easy debugging and observation.

[0179] The specific working principle of the paper pickup system of the present invention is as follows:

[0180] When the machine is turned on, the paper feeding assembly 211 is located on the side of the translation drive assembly 212 close to the paper feeding mechanism 230, the paper feeding assembly 211 is docked with the paper feeding mechanism 230, and the paper aligner 222 is in the avoidance position; when the paper pickup system is running, the paper feeding mechanism 230 feeds the paper group to the paper feeding assembly 211, and when part of the paper group is transferred to the paper feeding assembly 211 (the paper group is detected by the first position sensor), the paper feeding mechanism 230 stops running, and thereafter, the paper feeding assembly feeds the paper group in the first direction until the paper group moves to the first waiting position (at this time, the paper group is located above the side of the paper feeding assembly 211 away from the paper feeding mechanism 230, and the paper group is detected by the second position sensor ), at this time, the paper feeding assembly 211 stops running and the paper group stops; then, the position switching assembly 221 drives the paper aligning member 222 to move to the paper blocking position; thereafter, the paper feeding assembly 211 conveys the paper group in the second direction, so that the paper group hits the paper aligning member 222, so that the multiple carton skins in the paper group are aligned; thereafter, the paper feeding assembly 211 conveys the paper group in the first direction again until the paper group is in the second waiting position (at this time, the paper group is located above the side of the paper feeding assembly 211 away from the paper feeding mechanism 230, and the paper group is detected by the second position sensor). During this process, the position switching assembly 221 can drive the paper aligning member 222 to move to the avoidance position;

[0181] Afterwards, when the paper picking device 300 is out of paper, the translation drive assembly 212 drives the paper feeding assembly 211 to move along the first direction until the paper feeding assembly 211 is in the paper feeding position (at this time the paper feeding assembly 211 is detected by the third position sensor). At this time, the paper feeding assembly 211 is basically located above the paper picking mechanism 310; then, the paper feeding assembly 211 conveys the paper group along the first direction again until the paper group hits the paper stopper 323 of the first paper stopper mechanism 320. Thereafter, the paper feeding assembly 211 continues to operate, and the translation drive assembly 212 drives the paper feeding assembly 211 to move along the second direction until the paper feeding assembly 211 moves to the third waiting position (at this time the paper feeding assembly 211 is detected by the fourth position sensor) (in this process, it is only necessary to ensure that the paper stopper 323 has a blocking effect on the paper group, and the paper stopper 323 does not need to be set similar to the paper stopper in the publication number CN110937374A The strip grid of the grid plate can improve the problem of denting, deformation or even tearing of the carton skin), the translation drive component 212 stops driving the paper feeding component 211, and the paper feeding component 211 also stops providing driving force to the paper group (after that, the paper feeding mechanism 210 waits for the paper on the paper feeding mechanism 230 to be transferred again). In this process, the paper group will fall onto the paper picking mechanism 310. When the paper group falls, the four sides of the paper group will be respectively attached to the paper stop 323, the second paper stop 3322 and the side stop 3512 to ensure the positioning accuracy after falling. Among them, the second paper stop 3322 will lift the side of the paper group close to the second paper stop 3322, so that the paper group forms a certain angle, and the carton skin of the bottom layer of the paper group forms a certain angle to enter the paper picking gap; at this time, the paper picking component 312 can rub the carton skins in the paper group one by one between the roller 500 and the paper pressure wheel group 460.

[0182] When the sensor (not shown in the figure, it can be a photoelectric sensor) detects that there is no carton cover on the paper picking mechanism 310, the paper feeding mechanism 230 then transports the paper group to the paper feeding mechanism 210.

[0183] The present invention also provides a paper rubbing method, which is applied to the above-mentioned paper rubbing system. The paper rubbing method includes:

[0184] When the paper group reaches the feeding position, the paper feeding assembly 211 drives the paper group to move along the first direction, so that the entire paper group is carried by the paper feeding assembly 211 and is located at the first waiting position;

[0185] The position switching component 221 moves the paper aligning member 222 to the paper blocking position;

[0186] The paper feeding assembly 211 drives the paper group to move along the second direction, so that the paper group abuts against the paper aligning member 222;

[0187] The paper feeding assembly 211 drives the paper group to move along the first direction until the paper group is in the second waiting position;

[0188] The translation drive assembly 212 drives the paper feeding assembly 211 to move along the first direction until the paper feeding assembly 211 is in the paper feeding position;

[0189] The paper feeding assembly 211 drives the paper set to move along the first direction so that the paper set abuts against the paper stopper 323;

[0190] The paper feeding assembly 211 continuously provides a driving force to move the paper group in the first direction, and the translation driving assembly 212 drives the paper feeding assembly 211 to move in the second direction until the paper feeding assembly 211 moves to the third waiting position and causes the paper group to fall onto the paper pickup mechanism 310;

[0191] The paper picking mechanism 310 picks out the multiple carton wrappers in the paper group from bottom to top through the paper picking gap in sequence.

[0192] It should be noted that, in other embodiments, the paper group on the paper feeding assembly 211 may not be neatly processed, and the paper picking method includes:

[0196] The paper feeding assembly 211 continuously provides a driving force to move the paper group in the first direction, and the translation driving assembly 212 drives the paper feeding assembly 211 to move in the second direction until the paper feeding assembly 211 moves to the third waiting position and causes the paper group to fall onto the paper pickup mechanism 310;
