[0053] like Figure 1 As shown, an embodiment of the present invention provides a paper-crushing device 100, which can crush a stack of cardboard boxes one by one.

[0054] Combination Figure 1 and Figure 2 The paper feeding device 100 includes a paper feeding mechanism 110, which includes a drive assembly 111 and a paper feeding assembly 112. The drive assembly 111 and the paper feeding assembly 112 are driven together. The paper feeding mechanism 110 is mounted on the base frame 150.

[0055] Combination Figure 3 and Figure 4 The paper feed assembly 112 includes a mounting frame 1121, two drive wheels 1122, and a paper feed belt 1123.

[0056] Mounting bracket 1121 serves as the mounting base, which can be fixed to the base frame 150 and also provide mounting positions for other components.

[0057] Two drive wheels 1122 are spaced apart on the mounting frame 1121 along a preset direction.

[0058] Specifically, two drive wheels 1122 are arranged side by side and spaced apart along a preset direction, and the axes of the two drive wheels 1122 are parallel to each other. Each drive wheel 1122 is rotatable relative to the mounting bracket 1121, and each drive wheel 1122 can rotate around its own axis.

[0059] The mounting bracket 1121 includes a mounting block 11211 and mounting side plates 11212 arranged side by side on both sides of the mounting block 11211 at intervals. Two drive wheels 1122 are arranged between the two mounting side plates 11212 and are spaced apart along a preset direction.

[0060] Furthermore, the mounting bracket 1121 also includes a mounting shaft 11213 connected between two mounting side plates 11212. The two mounting shafts 11213 are arranged side by side and spaced apart along a preset direction, and two transmission wheels 1122 are rotatably sleeved on the two mounting shafts 11213 respectively.

[0061] It should be noted that one of the transmission wheels 1122 is defined as the driving wheel 11221, and the other transmission wheel 1122 is defined as the driven wheel 11222. One of the mounting shafts 11213 is defined as the first mounting shaft 112131, and the other mounting shaft 11213 is defined as the second mounting shaft 112132. The driving wheel 11221 is rotatably mounted on the first mounting shaft 112131, and the driven wheel 11222 is rotatably mounted on the second mounting shaft 112132.

[0062] Furthermore, a first bearing is provided between the driving wheel 11221 and the first mounting shaft 112131, and a second bearing is provided between the driven wheel 11222 and the second mounting shaft 112132.

[0063] The paper feed belt 1123 is fitted around the two drive wheels 1122.

[0064] Specifically, the two ends of the paper feed belt 1123 are respectively sleeved on the two drive wheels 1122. The paper feed belt 1123 and the two drive wheels 1122 mesh with each other. When the drive wheel 11221 rotates, the paper feed belt 1123 can run. When the paper feed belt 1123 runs, it drives the driven wheel 11222 to rotate.

[0065] The drive assembly 111 is connected to the drive wheel 11221. The drive assembly 111 is used to drive the drive wheel 11221 to rotate, thereby causing the paper feed belt 1123 to run.

[0066] Furthermore, the outer side of the paper feed belt 1123 can be coated with glue to increase the friction between it and the cardboard box, making it easier to feed the paper.

[0067] Combination Figure 3 and Figure 4The paper feed assembly 112 also includes a tensioning unit 1124, which includes a bracket 11241 rotatably connected to the mounting frame 1121 and a tensioning wheel 11242 connected to the bracket 11241. The tensioning wheel 11242 abuts against the inner wall of the paper feed belt 1123. The bracket 11241 is configured to rotate so that the position of the tensioning wheel 11242 can be adjusted to change the tension of the paper feed belt 1123.

[0068] Understandably, the tensioning wheel 11242 abuts against the inner wall of the paper feed belt 1123, thus keeping the paper feed belt 1123 taut and improving transport efficiency. Of course, by rotating the bracket 11241, the position of the tensioning wheel 11242 can be adjusted, thereby changing the tension of the paper feed belt 1123. Furthermore, the position of the tensioning wheel 11242 can be adjusted to accommodate paper feed belts 1123 of different lengths, ensuring that the tension of the paper feed belt 1123 is within a suitable range.

[0069] Combination Figure 3 and Figure 4 In some embodiments, the paper feed assembly 112 further includes a support 1125 connected to the mounting bracket 1121 and located within the space formed around the paper feed belt 1123, and a retainer 1126 disposed on the support 1125, the retainer 1126 abutting against the bracket 11241 so that the tension wheel 11242 abuts against the inner wall of the paper feed belt 1123.

[0070] Specifically, the paper feed belt 1123 is a closed structure with its ends connected. A support member 1125 is installed within the enclosed internal space formed by the belt. The support member 1125 is also connected to two mounting side plates 11212, used to increase the strength of the mounting frame 1121. A retaining member 1126 is provided on the support member 1125 and is used to abut against the bracket 11241, thereby allowing the bracket 11241 to apply force to the tension wheel 11242, causing the tension wheel 11242 to abut against the inner wall of the paper feed belt 1123, thus keeping the paper feed belt 1123 in a taut state.

[0071] Specifically, one end of the bracket 11241 is rotatably connected to the mounting bracket 1121, and the other end is connected to the tensioning wheel 11242.

[0072] like Figure 4 As shown, in one embodiment, the abutment 1126 is threadedly connected to the support 1125, and the abutment 1126 can be operatively driven to rotate the bracket 11241 to change the tension between the tension wheel 11242 and the paper feed belt 1123.

[0073] It is understandable that the abutment 1126 can be made of screws, which are threadedly connected to the support 1125. By rotating the abutment 1126, the position of the abutment 1126 can be changed. Since the abutment 1126 abuts against the bracket 11241, the change in the position of the abutment 1126 will adjust the angle of the bracket 11241, thereby changing the tightness between the tension wheel 11242 and the paper feed belt 1123.

[0074] Specifically, one end of the bracket 11241 is rotatably connected to the second mounting shaft 112132, and the other end of the bracket 11241 is connected to the tension wheel 11242. The tension wheel 11242 is used to abut against the inner wall of the lower side of the paper feed belt 1123. The abutment 1126 is threadedly connected to the support 1125. Rotating the abutment 1126 can make the abutment 1126 rise and fall. After the abutment 1126 rises, the force between the tension wheel 11242 and the paper feed belt 1123 decreases. After the abutment 1126 falls, the force between the tension wheel 11242 and the paper feed belt 1123 increases.

[0075] It should be noted that after the position of the tension wheel 11242 is adjusted, other screws can be used to lock the end of the bracket 11241 away from the tension wheel 11242 to the second mounting shaft 112132, further improving the stability of the bracket 11241.

[0076] In other embodiments, the abutment 1126 is a telescopic member, such as an electric push rod, which can drive the bracket 11241 to rotate to change the tightness between the tension wheel 11242 and the paper feed belt 1123.

[0077] like Figure 4 As shown, the tensioning wheel 11242 is rotatably connected to the bracket 11241, and the tensioning wheel 11242 rolls with the inner wall of the paper feed belt 1123.

[0078] It is understandable that the tensioning wheel 11242 can rotate relative to the support 11241. When the paper feed belt 1123 is running, the paper feed belt 1123 drives the tensioning wheel 11242 to roll, which helps to reduce the friction between the tensioning wheel 11242 and the paper feed belt 1123 and reduce wear.

[0079] Combination Figure 4 and Figure 5 In some embodiments, the paper feed assembly 112 further includes a first gear 1128 coaxially arranged and connected to the drive wheel 11221; the drive assembly 111 includes a first rotary drive member 1111, a drive shaft 1112 drivenly connected to the first rotary drive member 1111, and a second gear 1113 sleeved on the drive shaft 1112, the second gear 1113 meshing with the first gear 1128.

[0080] It is understood that the first rotary drive 1111 is used to drive the transmission shaft 1112 to rotate around the axis of the transmission shaft 1112, thereby driving the second gear 1113 to rotate. The second gear 1113 can drive the first gear 1128 to rotate, thereby driving the drive wheel 11221 to rotate, thus realizing the operation of the paper feed belt 1123.

[0081] Specifically, the first gear 1128 is coaxially arranged and fixedly connected with the drive wheel 11221, the second gear 1113 is sleeved on the transmission shaft 1112 and can rotate with the transmission shaft 1112, and the first rotary drive component 1111 is a motor used to drive the transmission shaft 1112 to rotate.

[0082] like Figure 5 As shown, in some embodiments, the drive assembly 111 further includes a support bearing assembly 1114 sleeved on the middle of the drive shaft 1112.

[0083] Understandably, the support bearing assembly 1114 is used to support the middle part of the drive shaft 1112, thereby reducing the degree of bending of the drive shaft 1112.

[0084] Specifically, the support bearing assembly 1114 includes a support bearing 11141 sleeved in the middle of the drive shaft 1112 and a support 11142 supporting the support bearing 11141, wherein the support 11142 is disposed on the base frame 150.

[0085] like Figure 1 As shown, in some embodiments, the paper feeding device 100 further includes a first paper-stopping mechanism 120, which is disposed on the base frame 150 and combined with... Figure 1 and Figure 6 The first paper-blocking mechanism 120 includes a first paper-blocking component 121 disposed opposite to the paper-flicking mechanism 110. A paper-passing gap is formed between the first paper-blocking component 121 and the paper-flicking mechanism 110. The paper-flicking mechanism 110 is used to carry the carton skin and drive the carton skin to move along a preset direction to pass through the paper-passing gap.

[0086] It should be noted that a paper passage gap is formed between the first paper stop assembly 121 and the paper feed belt 1123. The paper feed belt 1123 is used to carry the carton skin and drive the carton skin to move along a preset direction to pass through the paper passage gap.

[0087] Understandably, the distance between the first paper stop assembly 121 and the paper feeding belt 1123, i.e., the width of the paper feeding gap, is greater than the thickness of one cardboard box and less than the thickness of two cardboard boxes. When a stack of cardboard boxes is transported by the paper feeding belt 1123, the bottommost cardboard box can pass through the paper feeding gap. Thus, under the action of the paper feeding mechanism 110, the cardboard boxes can be fed out one by one.

[0088] Combination Figure 7 and Figure 8 Furthermore, the first paper-stopping assembly 121 includes a first paper-stopping member 1211 and a paper-pressing member 1212 arranged sequentially along a preset direction.

[0089] Understandably, the distance between the first paper stop 1211 and the paper feeding belt 1123 is greater than the thickness of one cardboard box skin but less than the thickness of two cardboard box skins. Similarly, the distance between the pressing component 1212 and the paper feeding belt 1123 is also greater than the thickness of one cardboard box skin but less than the thickness of two cardboard box skins. When a stack of cardboard box skins is transported by the paper feeding belt 1123, due to the obstruction of the first paper stop 1211, only the bottommost cardboard box skin enters the gap between the first paper stop 1211 and the paper feeding belt 1123 under the transport action of the paper feeding mechanism 110. As the bottommost cardboard box skin continues to be transported, it enters the gap between the pressing component 1212 and the paper feeding belt 1123. The pressing component 1212 acts as a limiter for the cardboard box skin, which can improve the problem of the cardboard box skin jumping during transport and help it enter subsequent processes in a more stable posture.

[0090] Furthermore, the side of the paper pressing component 1212 closest to the paper feed gap is the paper pressing plane 12121. The paper pressing plane 12121 is parallel to the carton skin entering the paper feed gap, and the contact area between the paper pressing plane 12121 and the carton skin is large, which helps to suppress the jumping of the carton skin during transportation.

[0091] like Figure 3 As shown, in some embodiments, the paper feed assembly 112 further includes a pad 1127 connected to the mounting bracket 1121, wherein the pad 1127 may be connected to the mounting side plate 11212 or disposed on the support member 1125.

[0092] Furthermore, the paper feed belt 1123 has a paper feed portion 11231 disposed opposite to the first paper stop assembly 121. The paper feed assembly 112 also includes a pad 1127 connected to the mounting bracket 1121. The pad 1127 is supported on the paper feed portion 11231 to make the paper feed portion flat.

[0093] Understandably, when a stack of cardboard boxes is transported by the paper feeding belt 1123, the bottommost cardboard box can pass through the gap between the first paper stop 1211 and the paper feeding section 11231. Thus, under the action of the paper feeding assembly 112, the cardboard boxes can be fed out one by one. The use of the pad 1127 to support the paper feeding section 11231 makes the section flatter, which is beneficial for paper feeding.

[0094] Combination Figure 7 and Figure 8In some embodiments, the first paper-stopping mechanism 120 further includes a gap adjustment component 122 that is tractively connected to the first paper-stopping assembly 121. The gap adjustment component 122 is operable to adjust the distance between the first paper-stopping assembly 121 and the paper-feeding mechanism 110 to adjust the width of the paper feed gap.

[0095] Understandably, the distance between the first paper stop assembly 121 and the paper feeding mechanism 110 can be adjusted according to the thickness of the cardboard box, thereby adjusting the width of the paper feed gap to accommodate cardboard boxes of different thicknesses.

[0096] Combination Figure 8 and Figure 9 Specifically, the gap adjustment assembly 122 includes a first adjusting rod 1222, a second adjusting rod 1223 pulverizedly connected to the first adjusting rod 1222, and an adjusting screw 1224 pulverizedly connected to the second adjusting rod 1223. The adjusting screw 1224 is threadedly connected to the first paper stop assembly 121. The axial direction of the adjusting screw 1224 is parallel to the width direction of the paper gap. A first bevel gear is provided at the end of the adjusting screw 1224 away from the paper gap. The axial direction of the second adjusting rod 1223 is parallel to a preset direction. A second bevel gear meshing with the first bevel gear and a third bevel gear spaced apart from the second bevel gear along the axial direction of the second adjusting rod 1223 are sleeved on the second adjusting rod 1223. The first adjusting rod 1222 is perpendicular to the second adjusting rod 1223. A fourth bevel gear meshing with the third bevel gear is sleeved on the first adjusting rod 1222.

[0097] Rotating the first adjusting rod 1222 can drive the second adjusting rod 1223 to rotate, which in turn drives the adjusting screw 1224 to rotate, thereby causing the first paper stop assembly 121 to move along the axial direction of the adjusting screw 1224, thus adjusting the distance between the first paper stop assembly 121 and the paper feeding mechanism 110.

[0098] It should be noted that the gap adjustment assembly 122 also includes a support plate 1221 disposed on the base frame 150. The support plate 1221 is provided with a first bearing seat 1225 and a second bearing seat 1226. The first adjusting rod 1222 passes through the first bearing seat 1225, and the first bearing seat 1225 is used to support the first adjusting rod 1222. The second adjusting rod 1223 passes through the second bearing seat 1226, and the second bearing seat 1226 is used to support the second adjusting rod 1223.

[0099] It should be noted that the first paper stop assembly 121 is restricted to rotate with the adjusting screw 1224 by a limiting structure. When the adjusting screw 1224 rotates, it can only drive the first paper stop assembly 121 to move along the axial direction of the adjusting screw 1224. The limiting structure can be a guide rail.

[0100] like Figure 9As shown, further, the first paper stop 1211 is integrally connected to the connecting block 1214, and the paper pressing component 1212 is connected to the connecting block 1214. The connecting block 1214 may have a strip-shaped hole, the length of which is parallel to the width of the paper feed gap. The paper pressing component 1212 is fixed to the connecting block 1214 with bolts. By providing the strip-shaped hole, the position of the paper pressing component 1212 can be adjusted, thereby adjusting the gap between the paper pressing block and the paper feed belt 1123. Further, the connecting block 1214 is connected to the first connecting part 1215 by screws, the first connecting part 1215 is connected to the second connecting part 1216 by screws, and the second connecting part 1216 is connected to the mounting plate 1217 by screws. The mounting plate 1217 is fixed to the base frame 150.

[0101] The first paper-stopping assembly 121 also includes a connecting plate 1213 connected to the connecting block 1214, and the connecting plate 1213 is provided with a screw hole for the adjusting screw 1224 to pass through.

[0102] Combination Figure 6 and Figure 7 It should be noted that the first paper-stopping mechanism 120 also includes a paper stop plate 123. The paper stop plate 123 and the first paper-stopping assembly 121 are arranged sequentially along a preset direction, and the end of the paper stop plate 123 near the paper-feeding mechanism 110 is farther away from the paper-feeding mechanism 110 than the end of the first paper-stopping assembly 121 near the paper-feeding mechanism 110. Specifically, the end of the paper stop plate 123 near the paper-feeding belt 1123 is farther away from the paper-feeding mechanism 110 than the end of the first paper-stopping assembly 121 near the paper-feeding belt 1123. The paper stop plate 123 can limit the movement of a stack of paper placed on the paper-feeding assembly 112.

[0103] It should be noted that, as Figure 8 The baffle plate 123 is connected to the first connecting frame 124, and the first connecting frame 124 is fixed to the base frame 150, wherein the support plate 1221 is fixed to the base frame 150.

[0104] like Figure 1 As shown, in some embodiments, the paper feeding device 100 further includes a second paper blocking mechanism 130, which is arranged sequentially and at intervals with the first paper blocking mechanism 120 along a preset direction.

[0105] Understandably, a stack of cardboard boxes can be confined between the first paper-blocking mechanism 120 and the second paper-blocking mechanism 130.

[0106] Combination Figure 1 and Figure 10Furthermore, the second paper-stopping mechanism 130 includes a distance adjustment component 131 and a second paper-stopping component 132 tractively connected to the distance adjustment component 131. The second paper-stopping component 132 and the first paper-stopping component 121 are arranged sequentially and at intervals along a preset direction. The distance adjustment component 131 can be operably adjusted to adjust the distance between the second paper-stopping component 132 and the first paper-stopping component 121. In this way, it can be applied to the limiting of carton skins of different sizes.

[0107] like Figures 10 to 12 As shown, specifically, the distance adjustment assembly 131 includes a second rotary drive 1311 and a distance adjustment screw 1312 drivenly connected to the second rotary drive 1311, and the second paper stop assembly 132 is threadedly connected to the distance adjustment screw 1312.

[0108] The second rotary drive 1311 can be a motor, used to drive the distance adjusting screw 1312 to rotate. The axis of the distance adjusting screw 1312 is parallel to a preset direction. When the distance adjusting screw 1312 rotates, it drives the second paper stop assembly 132 to move closer to or further away from the first paper stop assembly 121.

[0109] The distance adjustment component 131 also includes a guide shaft 1313 extending in a preset direction. The guide shaft 1313 passes through the second paper stop component 132 and guides the second paper stop component 132. At the same time, it can also limit the rotation of the second paper stop component 132 driven by the distance adjustment screw 1312.

[0110] The guide shaft 1313 is connected to two second connecting frames 133 at both ends. The second connecting frames 133 are mounted on the base frame 150, and the two ends of the distance adjusting screw 1312 are respectively mounted on the two second connecting frames 133 via bearings.

[0111] In some embodiments, the second paper-stopping assembly 132 includes a connecting frame 1321, a second paper-stopping element 1322 disposed on the connecting frame 1321, and a distance adjustment assembly 131 connected to the connecting frame 1321.

[0112] Specifically, the connecting frame 1321 is provided with a threaded sleeve 13212 through which the distance adjusting screw 1312 passes, and a through hole through which the guide shaft 1313 passes.

[0113] Furthermore, the number of second paper guides 1322 can be set to multiple, and the multiple second paper guides 1322 are spaced apart along a direction parallel to a preset direction, and the distance between two adjacent second paper guides 1322 is adjustable, so as to adapt to various sizes of cardboard boxes.

[0114] The second paper-stopping assembly 132 also includes an adjusting tube 1323 disposed on the connecting frame 1321. The second paper-stopping component 1322 is disposed on the adjusting tube 1323 via a connecting clamp 1324. The connecting clamp 1324 is locked by a locking bolt. When the locking bolt is removed, the position of the second paper-stopping component 1322 can be adjusted.

[0115] It should be noted that the second paper guide 1322 can also lift the carton skin, making the carton skin at a certain angle, which is conducive to passing through the paper feed gap.

[0116] In some embodiments, the paper feeding device 100 further includes a paper holder mechanism 140, which is disposed between the second paper stop assembly 132 and the first paper stop assembly 121.

[0117] Understandably, the paper support mechanism 140 can support the cardboard box skin. On the one hand, it can reduce the risk of the cardboard box skin collapsing due to its softness. On the other hand, it can also make the front end of the cardboard box skin tilt downwards, making it easier for the cardboard box skin to be twisted out through the paper feed gap.

[0118] Specifically, the paper tray mechanism 140 includes a clamping block 142 and a support rod 141 disposed on the clamping block 142. A connecting screw 143 is disposed below the clamping block 142, and the connecting screw 143 is threadedly connected to the mounting bracket 1121.

[0119] like Figure 14 As shown, in some embodiments, the paper feeding device 100 further includes a side paper blocking mechanism 160, which is used to limit the left and right sides of the carton skin located on the paper feeding mechanism 110. In this way, under the combined action of the first paper blocking mechanism 120, the second paper blocking mechanism 130 and the side paper blocking mechanism 160, the carton skin can be limited in all four directions.

[0120] like Figure 15 As shown, the side paper blocking mechanism 160 includes two side paper blocking components 161 that are spaced apart and arranged opposite to each other. The spacing direction of the two side paper blocking components 161 is horizontal and perpendicular to a preset direction. The two side paper blocking components 161 can respectively limit the left and right sides of the carton skin.

[0121] Furthermore, the distance between the two side paper-blocking assemblies 161 is adjustable, thus accommodating carton skins of different sizes.

[0122] Specifically, the side paper-blocking mechanism 160 also includes two width-adjusting screws 162 extending along the interval direction of the two side paper-blocking assemblies 161. One side paper-blocking assembly 161 is defined as the left side paper-blocking assembly, and the other side paper-blocking assembly 161 is defined as the right side paper-blocking assembly. One width-adjusting screw 162 is a first width-adjusting screw, and the other width-adjusting screw 162 is a second width-adjusting screw. The left half of the first width-adjusting screw is a threaded section, and the right half is a smooth section. The left half of the second width-adjusting screw is a smooth section, and the right half is a threaded section. Both side paper-blocking assemblies 161 are passed through by the two width-adjusting screws 162. The left side paper-blocking assembly is threadedly connected to the threaded section of the first width-adjusting screw, and the left side paper-blocking assembly is slidably engaged with the smooth section of the second width-adjusting screw. The right side paper-blocking assembly is threadedly connected to the threaded section of the second width-adjusting screw, and the right side paper-blocking assembly is slidably engaged with the smooth section of the first width-adjusting screw.

[0123] It is understandable that by rotating the first width adjusting screw, the left paper stop assembly can be moved, and by rotating the second width adjusting screw, the right paper stop assembly can be moved. The two side paper stop assemblies 161 can be adjusted independently.

[0124] Specifically, both the left and right paper stop assemblies are provided with threaded sleeves and sliding sleeves. The threaded sleeve on the left paper stop assembly is for the threaded section of the first width adjusting screw to pass through, and the sliding sleeve on the left paper stop assembly is for the smooth section of the second width adjusting screw to pass through. The threaded sleeve on the right paper stop assembly is for the threaded section of the second width adjusting screw to pass through, and the sliding sleeve on the right paper stop assembly is for the smooth section of the first width adjusting screw to pass through.

[0125] Furthermore, handwheels are also provided on the two width adjusting screws 162 to facilitate the operator to rotate the width adjusting screws 162.

[0126] In some embodiments, the side paper blocking mechanism 160 further includes two side paper blocking mounting brackets 166 and two side paper blocking mounting blocks 167 respectively disposed on the two side paper blocking mounting brackets 166. Both ends of two width adjusting screws 162 are respectively mounted on the two side paper blocking mounting blocks 167 via bearings, and both width adjusting screws 162 can rotate. The side paper blocking mounting brackets 166 are fixed to the base frame 150.

[0127] Furthermore, the side paper-blocking mechanism 160 also includes a first lead screw support bracket 163 and a second lead screw support bracket 164. The first lead screw support bracket 163 is screwed to the base frame 150, and the second lead screw support bracket 164 is fixed to the first lead screw support bracket 163. The second lead screw support bracket 164 is fixedly connected to a lead screw support block 165. The lead screw support block 165 is provided with two bearings for the two width-adjusting lead screws 162 to pass through, and the lead screw support block 165 is used to support the middle part of the width-adjusting lead screws 162.

[0128] Furthermore, the side baffle assembly 161 includes a side baffle mounting block 1611 and a side baffle 1612 connected to the side baffle mounting block 1611. The side baffle mounting block 1611 is mounted on the width adjusting screw 162 and is used for two width adjusting screws 162 to pass through.

[0129] Furthermore, a side baffle 1612 is provided with a side baffle auxiliary support plate 1613, which can be supported by a support rod 141, and the support rod 141 can assist in supporting the side baffle 1612.

[0130] This utility model also provides a carton wrapping machine, which includes the paper feeding device 100 of the above embodiment.

[0131] The carton wrapping machine of this utility model has the aforementioned paper-feeding device 100. When a stack of carton skins is transported by the paper-feeding mechanism 110, due to the blocking effect of the first paper stop 1211, only the bottommost carton skin enters the gap between the first paper stop 1211 and the paper-feeding belt 1123 under the transport action of the paper-feeding mechanism 110. As the bottommost carton skin continues to be transported, the carton skin enters the gap between the paper pressing component 1212 and the paper-feeding belt 1123. The paper pressing component 1212 plays a limiting role on the carton skin, which can improve the problem of the carton skin jumping during the transport process and help the carton skin enter the subsequent process in a more stable posture.
