Description

Technical Field

[0001] The present invention relates to the technical field of packaging boxes, and in particular to a packaging box loading device and a box opening system. Background Art

[0002] Cartons used in logistics packaging typically arrive in cardboard form, flat sheets rather than folding into a three-dimensional structure. They are typically bundled with multiple layers of cardboard (flat nylon or PE straps) for easy transport, typically in bundles of 10. Therefore, during use, the ties must be cut before the individual cardboard sheets are opened and folded into a three-dimensional box. Initially, this was done manually, cutting and removing the ties, and then manually opening and folding each cardboard sheet into a box. With the development of the manufacturing economy, manual cardboard opening and folding has become inadequate for production needs. Consequently, automated carton openers have emerged, opening at speeds of approximately 5-10 boxes per minute. However, the operations of cutting the ties and loading the incoming cardboard bundles are still performed manually. Therefore, each carton opener requires one or two workers to load the cardboard. If operating in a two-shift system, two to four workers are required. While this ensures the normal operation of the carton opener, the labor cost is high.

[0003] In recent years, with the deepening and application of production automation, carton openers with a capacity of 5-10 cartons per minute are basically unable to meet the packaging requirements of the industry. The market has begun to develop high-speed horizontal carton openers, which can open cartons at a speed of 30-40 cartons per minute. At the same time, auxiliary equipment such as tape cutting equipment, robotic palletizers and automatic loaders are used to achieve combined loading of cardboard. Although this carton opening process can effectively replace manual loading and increase the speed of cardboard loading, it still has the following problems:

[0004] 1. The tape cutting equipment can generally only complete the tape cutting operation of the packaging tape. The cut packaging tape still needs to be manually assisted to be pulled out. Moreover, the tape cutting component and the hook component of the existing tape cutting equipment are generally located in the same component. The hook component is mainly used to hook the packaging tape before cutting. The cut packaging tape is easy to loosen or shift, which is not conducive to the extraction of the packaging tape.

[0005] 2. The loading speed of cardboard is limited by the coordination between the independent functional equipment. Although the loading speed is higher than that of manual loading, it still cannot meet the production capacity requirements of automatic unpacking equipment. The loading speed needs to be further improved.

[0006] 3. The introduction of various automated equipment not only greatly increases the equipment cost, but the assembled production line also often requires a larger production space; at the same time, it also increases the difficulty in equipment manufacturing, transportation, debugging, maintenance, etc.

[0007] In summary, researching a technology that can replace manual loading, reduce labor costs and difficulty of manual operation, and improve packaging efficiency is of great significance for accelerating the production capacity of various industries and promoting the development of various industries. Summary of the Invention

[0008] To address the shortcomings of the prior art, the present invention provides a packaging box loading device. The strap cutting mechanism located on the feed section at the top of the device frame not only automatically cuts the packaging paper placed thereon for strap cutting, but also promptly removes the packaging strap after strap cutting, effectively improving strap cutting efficiency. Furthermore, compared to prior art strap cutting mechanisms in which the strap cutting and hooking components are located in the same assembly and only hook the packaging strap for cutting, the strap cutting mechanism effectively positions the strap after cutting, preventing it from bouncing off after cutting and requiring secondary positioning for subsequent strap removal.

[0009] In terms of structural layout, the device is composed of a tape cutting mechanism, a material storage mechanism and a material dividing mechanism which are arranged on the device frame in sequence from top to bottom. It can not only automatically realize the operations of tape cutting, material storage and material dividing of packaging paper, but also effectively replace manual loading operations, reduce labor costs and increase the loading speed of packaging paper. Moreover, the top-down integrated device structure can effectively reduce the overall occupied space of the device and improve the overall integration level of the device compared with the independent functional equipment in the prior art, thereby reducing the time for packaging paper to be transferred between independent equipment and further increasing the loading speed of packaging paper to adapt to the high production capacity requirements of automatic unpacking equipment.

[0093] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0094] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0095] Example 1:

[0096] Please see the attached Figure 1 The packaging box loading device of the embodiment of the present invention includes a device frame 100, and a tape cutting mechanism 200, a storage mechanism 300, and a material separation mechanism 400 arranged on the device frame 100 from top to bottom. The device frame 100 includes a feeding portion located at the top and a discharging portion located at the bottom. Furthermore, the tape cutting mechanism 200 is arranged on the feeding portion located at the top and is mainly used for cutting and pulling out the strapping packaging band; the material separation mechanism 300 is arranged below the tape cutting mechanism 200 and is mainly used for storing the packaging paper skin after the tape is cut; the material separation mechanism 400 is arranged on the discharging portion located at the bottom and is mainly used for separating multiple stacked paper skins so as to feed the single separated paper skins to the automatic box opening device.

[0097] Please refer to the attached Figure 2 The tape cutting mechanism 200 includes a first movable material stop assembly 210 and a second movable material stop assembly 220 which are relatively arranged at the same height on both sides of the device frame 100, a first push plate assembly 230 and a second push plate assembly 240 which are relatively arranged on both sides of the device frame 100 and form a tape cutting station between the first movable material stop assembly 210 and the second movable material stop assembly 220, a tape cutting assembly 250 arranged on the side where the first push plate assembly 230 is located, and a hook and pull tape assembly 260 arranged on the side where the second push plate assembly 240 is located. Among them, the first movable material stop assembly 210 and the second movable material stop assembly 220 are combined to be used for placing and limiting the packaging paper skin, so as to limit the bundling of the packaging paper skin in the vertical direction; the first push plate assembly 230 is arranged corresponding to the first movable material stop assembly 210, and the second push plate assembly 240 is arranged corresponding to the second movable material stop assembly 220. The two push plate assemblies are combined to be used for arranging and further limiting the bundling of packaging paper skin, and the two push plate assemblies and the two movable material stop assemblies are combined to form a tape cutting station; the tape cutting assembly 250 is used for cutting the packaging tape; the hook and pull tape assembly 260 is mainly used to pull the cut packaging tape out to a preset position, and to hook the packaging tape before cutting the tape to ensure the quality of the tape cutting.

[0098] The strap cutting mechanism 200 of this embodiment not only automatically cuts the packaging paper placed on it for cutting, but also promptly removes the packaging tape after cutting, effectively improving cutting efficiency. Furthermore, compared to conventional strap cutting mechanisms in which the strap cutting and hooking components are integrated into a single assembly and only hook the packaging tape for cutting, the strap cutting mechanism 200 effectively positions the severed packaging tape, preventing it from bouncing off after cutting and requiring secondary positioning for subsequent stripping.

[0099] Please refer to the attached Figure 3 In some embodiments, the first movable material stopper assembly 210 and the second movable material stopper assembly 220 each include a material stopper drive unit 221 disposed on the device frame 100, a material stopper unit 222 connected to the drive end of the material stopper drive unit 221 and movably disposed on the device frame 100, and a material stopper guide pin and guide sleeve unit 223 connected between the device frame 100 and the material stopper unit 222. Furthermore, the material stopper unit 222 includes a material stopper mounting plate 2221 connected to the drive end of the material stopper drive unit 221, and a plurality of material stopper modules 2222 disposed side by side on the material stopper mounting plate 2221 and passing through the device frame 100 to movably support the packaging box. Preferably, the material stopper drive unit 221 is a cylinder drive unit, and the material stopper modules 2222 are material stopper support roller modules.

[0100] When the blocking drive unit 221 is opened once, the blocking mounting plate 2221 connected thereto can be driven by it to move in a horizontal direction, thereby driving the multiple blocking modules 2222 connected thereto to extend between the two sides of the device frame 100, so that the blocking modules 2222 arranged on both sides of the device frame 100 form a storage platform for placing and vertically limiting the bundled packaging paper sheets loaded into the device. When the blocking drive unit 221 is opened a second time, the blocking mounting plate 2221 connected thereto can be driven by it to move in an opposite horizontal direction, thereby driving the multiple blocking modules 2222 connected thereto to retract into the device frame 100, so that the packaging paper sheets can fall onto the storage mechanism 300 after the strips are cut.

[0101] Please refer to the attached Figure 4 In some embodiments, the first push plate assembly 230 includes a first push plate 231 corresponding to the first movable material stop assembly 210, which is used to limit one side of the packaging paper in the tape cutting station, and a first push plate driving unit 232 that drives the first push plate 231 to move toward the tape cutting station; and the first push plate 231 is provided with a tape cutting groove 2312 for the tape cutting assembly 250 to at least partially pass through to cut and bundle the packaging tape.

[0102] Specifically, the first push plate driving unit 232 includes a first push plate driving module 2321 and a first slide rail slider group 2322 corresponding to the first movable material blocking assembly 210 and arranged on the device frame 100, and the driving end of the first push plate driving module 2321 and the slider of the first slide rail slider group 2322 are respectively connected to the first push plate 231; preferably, the first push plate driving module 2321 is a cylinder driving module, and its driving direction is parallel to the driving direction of the material blocking driving unit 221 in the first movable material blocking assembly 210; the sliding direction of the first slide rail slider group 2322 is parallel to the driving direction of the first push plate driving module 2321.

[0103] Furthermore, the first push plate 231 includes a first push plate body 2311 for realizing the shaping and limiting of the packaging paper, and a cutting groove 2312 corresponding to the cutting assembly 250 and opened on the first push plate body 2311; the design of the cutting groove 2312 can effectively avoid the cutting component in the cutting assembly 250, so that the cutting component can extend out of the first push plate body 2311 to cut the packaging tape used to bundle the packaging paper.

[0104] Please refer to the attached Figure 5 and 6 The second push plate assembly 240 includes a second push plate 241 corresponding to the second movable material blocking assembly 220, which is used to limit the other side of the packaging paper in the tape cutting station, and a second push plate driving unit 242 that drives the second push plate 241 to move toward the tape cutting station; and the second push plate 241 is provided with a hook groove 2412 for the hook and pull belt assembly 260 to at least partially pass through to hook the binding packaging belt.

[0105] Specifically, the second push plate driving unit 242 includes a second push plate driving module 2421 and a second slide rail slider group 2422 corresponding to the second movable stopper assembly 220, which are arranged on the device frame 100, and the sliders of the second push plate driving module 2421 and the second slide rail slider group 2422 are respectively connected to the second push plate 241; preferably, the second push plate driving module 2421 is a cylinder driving module, and its driving direction is parallel to the driving direction of the stopper driving unit 221 in the second movable stopper assembly 220; the sliding direction of the second slide rail slider group 2422 is parallel to the driving direction of the second push plate driving module 2421.

[0106] Furthermore, the second push plate 241 includes a second push plate body 2411 for combining with the first push plate 231 to realize the shaping and limiting of the packaging paper, and a hook belt groove 2412 corresponding to the hook belt assembly 260 and opened on the second push plate body 2411; the design of the hook belt groove 2412 can effectively avoid the hook belt component in the hook belt assembly 260, so that the hook belt component can reciprocate through the second push plate body 2411 to hook and pull out the packaging belt for bundling the packaging paper.

[0107] When the first push plate drive module 2321 is turned on, the first push plate 231 connected thereto can be driven by it to move toward the packaging paper until it contacts one side of the packaging paper. During this movement, the first slide block assembly 2322 can further guide the movement of the first push plate 231 to improve the accuracy and stability of the movement of the first push plate 231. Similarly, the second push plate 241 can be driven by the second push plate drive module 2421 and guided by the second slide block assembly 2422 to move toward the packaging paper until it contacts the other side of the packaging paper. The combination of the first push plate 231 and the second push plate 241 can further limit the packaging paper placed on the first movable material stop assembly 210 and the second movable material stop assembly 220, effectively preventing the packaging paper from shifting during the subsequent tape cutting process.

[0108] Please refer to the attached Figure 5 and 6 In some embodiments, the hook-and-tie assembly 260 includes a first hook-and-tie assembly 260a and a second hook-and-tie assembly 260b, and the first hook-and-tie assembly 260a and the second hook-and-tie assembly 260b are symmetrically arranged about a first horizontal direction, wherein the first horizontal direction is parallel to the direction of the hook-and-tie assembly 260 toward the strap cutting station. Furthermore, each of the first hook-and-tie assembly 260a and the second hook-and-tie assembly 260b includes a hook-and-tie unit 261 that moves along the first horizontal direction to hook the strapping strap and moves along the second horizontal direction to pull the strapping strap to a predetermined position, and a hook-and-tie drive unit that drives the hook-and-tie unit 261 to move along the first horizontal direction and / or the second horizontal direction; wherein the second horizontal direction is perpendicular to the first horizontal direction.

[0109] Taking the example of a hook-pull drive unit capable of driving the hook belt unit 261 to move along the first and second horizontal directions, the hook-pull drive unit specifically includes a belt drive module 2621 disposed on the device frame 100 with its driving direction parallel to the first horizontal direction, a belt slide rail slider assembly 2622 connected to the driving end of the belt drive module 2621 and disposed on the second push plate 241, a belt module mounting plate 2623 disposed on the slider of the belt slide rail slider assembly 2622, a belt slide rail slider assembly 2624 disposed on the belt module mounting plate 2623 with its sliding direction parallel to the second horizontal direction, and a belt drive module 2625 connected to the belt unit 261 and disposed on the belt module mounting plate 2623. Preferably, the belt drive module 2621 is a cylinder drive module, and the belt drive module 2625 is a belt pulley drive module.

[0110] Please refer to the attached Figure 7The hook belt unit 261 includes a unit linkage plate 2611 that is respectively connected to the belt in the belt pulley drive module and the slider in the hook belt slide rail slider group 2624, a hook belt driving sub-module 2612 arranged on the unit linkage plate 2611 and with a driving direction parallel to the first horizontal direction, a belt hook 2613 connected to the driving end of the hook belt driving sub-module 2612, and a belt pressing module 2614 that is opposite to the hook belt part of the belt hook 2613 and is arranged on the unit linkage plate 2611; preferably, the hook belt driving sub-module 2612 is a cylinder driving module, and the belt pressing module 2614 is a support column module.

[0111] During the tape cutting process, the drawstring drive module 2621 is turned on once, driving the hook tape module mounting plate 2623 connected thereto to move along the slide rail of the drawstring slide rail slider group 2622 toward the packaging paper skin, thereby driving the hook tape slide rail slider group 2624, the hook tape drive module 2625 and the hook tape unit 261 installed on the hook tape module mounting plate 2623 to move toward the packaging paper skin until the hook tape unit 261 and the packaging paper skin are against each other; subsequently, the hook tape unit 261 is driven by the hook tape drive module 2625 and guided by the hook tape slide rail slider group 2624. The hook belt driving submodule 2612 is opened, and the belt hook 2613 connected to it and hooking the packaging belt moves away from the packaging paper, and the packaging belt is pressed between the belt hook 2613 and the belt pressing module 2614; then, the belt pulling driving module 2621 is opened for the second time, pulling the packaging belt away from the packaging paper, until the packaging belt adjacent to the side of the belt cutting assembly 250 is close to the side of the packaging paper, so as to facilitate the cutting of the packaging belt and prevent the packaging belt from shifting or shrinking into the gap between the stacked packaging paper during the cutting process.

[0112] After the tape is cut, the tape drive module 2621 is activated three times, driving the hook unit 261 to continue moving away from the packaging paper to pull out the cut packaging tape. During the tape pulling process, the hook unit 261 can continue to move to a preset position under the drive of the hook drive module 2625 and the guidance of the hook rail slider assembly 2624. For example, if the preset position is between the first hook tape assembly 260a and the second hook tape assembly 260b, the hook unit 261 can continue to move to a position between the first hook tape assembly 260a and the second hook tape assembly 260b under the drive of the hook drive module 2625 and the guidance of the hook rail slider assembly 2624 to facilitate the centralized unloading of the packaging tape.

[0113] Please refer to the attached Figure 4In some embodiments, the tape cutting assembly 250 includes a tape cutting unit 251 that at least partially moves through the first push plate 231 and cuts the strapping packaging tape set in the tape cutting station, and a tape cutting drive unit 252 that drives the tape cutting unit 251 to move toward the tape cutting station.

[0114] Specifically, the belt cutting drive unit 252 includes a belt cutting drive module 2521 and a belt cutting slide rail slider group 2522, which are arranged on the first push plate 231 in the first push plate assembly 230 and whose movement direction is parallel to the second horizontal direction; preferably, the belt cutting drive module 2521 includes a belt pulley drive sub-module and a drag chain sub-module adjacent to each other on the first push plate 231, and a belt cutting linkage mounting plate whose one end is respectively connected to the belt pulley drive module sub-module and the drag chain sub-module and the other end is connected to the slider in the belt cutting slide rail slider group 2522.

[0115] At least two sets of strap cutting units 251 are spaced apart on the first push plate assembly 230 to simultaneously cut multiple strips of packaging paper, improving strap cutting efficiency. Furthermore, the strap cutting units 251 include a strap cutting drive submodule 2511, whose drive direction is parallel to the first horizontal direction and is mounted on the slider of the strap cutting rail slider assembly 2522, and a strap cutting module 2512, which is mounted on the driving end of the strap cutting drive submodule 2511. Preferably, the strap cutting drive submodule 2511 is a cylinder drive module, while the strap cutting module 2512 is a rotary shearing module or a punching module. The specific choice can be based on actual production needs, and any module that can perform the corresponding shearing function in the existing technology can be used.

[0116] When the packaging tape to be cut is pulled close to the side of the packaging paper by the first and second hook and pull assemblies 260a and 260b near the tape cutting assembly 250, the tape cutting drive module 2521 is activated, driving the tape cutting unit 251 along the tape cutting slide block assembly 2522 to a position corresponding to the packaging tape. Subsequently, the tape cutting drive submodule 2511 is activated, driving the tape cutting module 2512 disposed on the driving end of the tape cutting drive submodule 2511 through the tape cutting slot 2312 of the first push plate 231. The tape cutting module 2512 is then activated to cut the packaging tape. After cutting is completed, the tape cutting module 2512 is closed, and the tape cutting drive submodule 2511 is activated again, causing it to reset the tape cutting module 2512.

[0117] Please refer to the attached Figure 2 In some embodiments, the strap cutting mechanism 200 further includes a discharge assembly 270 for discharging the cut strapping packaging strap; preferably, the discharge assembly 270 is disposed at a preset position, for example, the preset position is between the first hook and pull strap assembly 260a and the second hook and pull strap assembly 260b. Figure 5 and 6Specifically, the discharge assembly 270 includes an entrainment conveying unit 271 disposed between the first hook-pull belt assembly 260a and the second hook-pull belt assembly 260b, a belt-pulling unit disposed on the second push plate assembly 240 corresponding to the feed end of the entrainment conveying unit 271, and a pushing unit 274 mounted on the device frame 100 corresponding to the discharge end of the entrainment conveying unit 271. Preferably, the belt-pulling unit includes a first belt-pulling unit 272 and a second belt-pulling unit 273 symmetrically disposed on both sides of the second push plate assembly 240.

[0118] Please refer to the attached Figure 8 The entrainment conveying unit 271 is used to convey the packaging belt to the outside of the device in a centralized manner. Its structure includes a first conveyor belt module 2711 arranged between the first hook belt assembly 260a and the second hook belt assembly 260b, which is driven in the reverse direction of the first horizontal direction; a conveyor belt driving module 2712 connected to the first conveyor belt module 2711 and arranged on the device frame 100; and a second conveyor belt module 2713 whose conveying end face is against the conveying end face of the first conveyor belt module 2711 and is mounted above the first conveyor belt module 2711; preferably, the conveyor belt driving module 2712 is a motor driving module.

[0119] The conveyor belt drive module 2712 is turned on, driving the upper conveying end surface of the first conveyor belt module 2711 connected to it to transmit in the opposite direction of the first horizontal direction, that is, to convey it away from the tape cutting station; when the packaging belt moves to the upper conveying end surface of the first conveyor belt module 2711, it can move away from the tape cutting station as the upper conveying end surface is conveyed; at the same time, the lower conveying end surface of the second conveyor belt module 2713, which is in contact with the upper conveying end surface of the first conveyor belt module 2711, can clamp the packaging belt between the two conveying end surfaces to convey the packaging belt to the outside of the device.

[0120] Please refer to the attached Figure 5 The first belt-pulling unit 272 and the second belt-pulling unit 273 both include a belt-pulling driving module 2721 arranged on the second push plate 241, and a swinging belt-pulling member 2722 connected to the driving end of the belt-pulling driving module 2721 and swingably arranged on the second push plate 241; preferably, the belt-pulling driving module 2721 is a cylinder driving module.

[0121] Since there is generally a certain distance between adjacent strapping bands, if the strapping bands are directly conveyed to the entrainment conveying unit 271 via the first and second hook-pull band assemblies 260a and 260b, the strapping bands between the second push plate 241 and the first and second hook-pull band assemblies 260a and 260b will form an angle with the conveying direction of the entrainment conveying unit 271, which can easily cause the strapping bands to flow out of the entrainment conveying unit 271 during conveyance. Therefore, the design of the first and second strapping units 272 and 273 can effectively shift the strapping bands adjacent to the second push plate 241 to a position close to the conveying centerline of the entrainment conveying unit 271, thereby further achieving centralized conveyance of the strapping bands and preventing the strapping bands from flowing out of the entrainment conveying unit 271 during conveyance.

[0122] Please refer to the attached Figure 6 The pushing unit 274 is used to push the packaging belt conveyed to the discharge end, further effectively improving the unloading of the packaging belt; its specific structure includes a pushing mounting frame 2741 mounted above the discharge end of the entrainment conveying unit 271, a pushing driving module 2742 arranged on the pushing mounting frame 2741, and a pushing plate 2743 arranged on the driving end of the pushing driving module 2742; preferably, the pushing driving module 2742 is a cylinder driving module.

[0123] In some embodiments, the discharge assembly 270 further includes a discharge hopper 275 connected to the pushing unit 274 for guiding the discharge of the packaging tape, as shown in the attached Figure 5 shown.

[0124] Example 2:

Among them, the device frame 100 includes a feeding part located at the top and a discharging part located at the bottom; further, the tape cutting mechanism 200 is arranged on the feeding part located at the top, and is mainly used for cutting and pulling out the strapping packaging tape; the material dividing mechanism 300 is arranged below the tape cutting mechanism 200, and is mainly used for storing the packaging paper skin after tape cutting; the material dividing mechanism 400 is arranged on the discharging part at the bottom, and is mainly used for dividing multiple stacked paper skins, so as to load the single divided paper skins onto the automatic box opening device. The main difference is that, based on Example 1, this embodiment further designs the storage mechanism 300 and the material dividing mechanism 400, and the specific design is as follows:

[0126] Please refer to the attached Figure 2The material storage mechanism 300 includes a first material storage assembly 310 and a second material storage assembly 320, which are arranged at the same height on both sides of the device frame 100, a first material transfer assembly 330 corresponding to the first material storage assembly 310 and arranged on the device frame 100, and a second material transfer assembly 340 corresponding to the second material storage assembly 320 and arranged on the device frame 100. The first material storage assembly 310 and the second material storage assembly 320 are used to store and store the packaging paper after cutting, and the first material transfer assembly 330 and the second material transfer assembly 340 are used to transfer the packaging paper to a pre-set reference position.

[0127] Please refer to the attached Figure 3 In some embodiments, both the first and second material storage assemblies 310 and 320 include a material storage drive unit 311 mounted on the device frame 100, a material storage unit 312 connected to the drive end of the material storage drive unit 311 and movably disposed on the device frame 100, and a material storage guide pin and sleeve unit 313 connected between the device frame 100 and the material storage unit 312. The material storage unit 312 includes a material storage mounting plate 3121 connected to the drive end of the material storage drive unit 311, and a plurality of material storage modules 3122 arranged side by side on the material storage mounting plate 3121 and passing through the device frame 100 to movably support the packaging box. Preferably, the material storage drive unit 311 is a cylinder drive unit, and the material storage modules 3122 are support roller modules. The operating principles of the first and second material storage assemblies 310 and 320 for material storage are the same as those of the first and second movable material blocking assemblies 210 and 220, and therefore will not be further described here.

[0128] Please refer to the attached Figure 3 In some embodiments, the first material shifting assembly 330 and the second material shifting assembly 340 each include a material shifting slide block unit 331 disposed on the device frame 100, with its movement direction parallel to the second horizontal direction; a material shifting drive unit 332 connected to the slider in the material shifting slide block unit 331 and disposed on the device frame 100; a position detection unit 333 disposed on the device frame 100 corresponding to the first material storage assembly 310 and the second material storage assembly 320; and a corner material shifting member 334 connected to the slider in the material shifting slide block unit 331 and used to shift the packaging box to the reference position. Preferably, the material shifting drive unit 332 is a cylinder drive unit; the position detection unit 333 is a photoelectric sensor unit, primarily used to detect the placement of the packaging cardboard to facilitate position adjustment of the packaging cardboard.

[0129] When the trimmed wrapper falls onto the first and second stocking assemblies 310 and 320, the position detection unit 333 detects its position. The material shifting drive unit 332 activates once, driving the connected corner shifting member 334 to shift the wrapper, further adjusting its position. Subsequently, the material shifting drive unit 332 activates a second time, driving the corner shifting member 334 to return to its position, extending outside the device frame 100.

[0130] Please refer to the attached Figure 2 The material distribution mechanism 400 is a pin distribution mechanism, comprising a first pin distribution assembly 410 and a second pin distribution assembly 420 which are arranged at the same height on both sides of the device frame 100 and are used to distribute the multiple stacked packaging paper sheets from the bottom to the bottom of the device in sequence. Figure 3 The first ejector material distribution assembly 410 and the second ejector material distribution assembly 420 both include an ejector linkage unit 411 mounted on the device frame 100, an upper ejector unit 412 and a lower ejector unit 413 connected to the ejector linkage unit 411 and alternately arranged at different heights on the device frame 100, and an ejector drive unit 414 connected to the ejector linkage unit 411 and arranged on the device frame 100; preferably, the ejector drive unit 414 is a cylinder drive unit.

[0131] Please refer to the attached Figure 9 The ejector linkage unit 411 includes two ejector linkage mounting plates 4111 relatively arranged on the same side of the device frame 100, an upper ejector linkage slide rail slider group 4112 and a lower ejector linkage slide rail slider group 4113 arranged at different heights on the ejector linkage mounting plates 4111, an upper ejector linkage limiting column 4114 arranged on the slider of the upper ejector linkage slide rail slider group 4112, a lower ejector linkage limiting column 4115 arranged on the slider of the lower ejector linkage slide rail slider group 4113, and a linkage rotating shaft 4116 rotatably arranged between the two opposite ejector linkage mounting plates 4111; the middle part is connected to the linkage rotating shaft 4116, one end of which is sleeved on the upper ejector linkage limiting column 4114 and the other end of which is sleeved on the lower ejector linkage limiting column 4115, and a material dividing linkage component 4118 arranged on the linkage rotating shaft 4116 and connected to the driving end of the ejector drive unit 414.

[0132] When the material distribution starts, the ejector drive unit 414 is turned on once, and the lower ejector unit 413 is driven to move toward the side close to the packaging paper skin through the linkage action of the ejector linkage unit 411 to support the multiple stacked packaging paper skins dropped into the mechanism. At this time, the upper ejector unit 412 is retreated to the outside of the device frame 100 under the action of the ejector linkage unit 411, without affecting the dropping of the packaging paper skins; subsequently, the ejector drive unit 414 is turned on for the second time, and the upper ejector unit 412 is driven to move toward the side close to the packaging paper skin through the linkage action of the ejector linkage unit 411, and inserted into the gap between the stacked packaging paper skins. At the same time, the lower ejector unit 413 is retreated to the outside of the device frame 100, causing the packaging paper skins below the upper ejector unit 412 to fall, thereby realizing the distribution and loading of the packaging paper skins.

[0133] A loading method applicable to the packaging box loading device in Examples 1 and 2 comprises the following steps:

[0134] S10, loading the bundled packaging paper into the tape cutting mechanism 200, using the tape cutting mechanism 200 to cut the packaging tape of the bundled packaging paper and then pulling it out;

[0135] S20, after the tape cutting is completed, the packaging paper skin falls into the storage mechanism 300 below the tape cutting mechanism 200 for collection and storage;

[0136] S30, using the material distribution mechanism 400 to distribute the multiple stacked packaging paper sheets from the bottom to the bottom of the device in sequence.

[0137] The step S10 includes the following steps:

[0138] S11. After loading the bundled packaging paper onto the storage platform formed by the first movable material blocking assembly 210 and the second movable material blocking assembly 220, the first push plate assembly 230 and the second push plate assembly 240 are started to further limit and arrange the bundled packaging paper.

[0139] S12. The first hook and pull belt assembly 260a and the second hook and pull belt assembly 260b, which are connected to the second push plate assembly 240 and are arranged on the same side of the device frame 100, hook one side of the packaging belt and pull it away from the packaging paper, so that the packaging belt adjacent to the side of the first push plate assembly 230 is close to the side edge of the packaging paper; then, the belt cutting assembly 250 arranged on the first push plate assembly 230 cuts the packaging belt.

[0140] S13, after the tape is cut, the first hook and pull tape assembly 260a and the second hook and pull tape assembly 260b pull the packaging tape toward the discharge assembly 270;

[0141] S14, the discharge assembly 270 discharges the cut packaging tape out of the device.

[0142] The specific actions of each mechanism and component have been explained in the structure section, so they will not be repeated here.

[0143] The packaging box loading device in Examples 1 and 2 is composed of a tape cutting mechanism 200, a material storage mechanism 300 and a material dividing mechanism 400 that are arranged on the device frame 100 in sequence from top to bottom. It can not only automatically realize the operations of tape cutting, material storage and material dividing of packaging paper from top to bottom, effectively replace manual loading operations, reduce labor costs, and increase the loading speed of packaging paper; and the top-down integrated device structure, compared with the various independent functional devices in the prior art, can effectively reduce the overall occupied space of the device and improve the overall integration level of the device, thereby reducing the time for packaging paper to be transferred between independent devices, and further increasing the loading speed of packaging paper to adapt to the high production capacity requirements of automatic unpacking equipment.
