Detailed Implementation

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0023] In the description of this application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or state relationship based on the orientation or state relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0024] Furthermore, in addition to indicating location or state relationships, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0025] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] Furthermore, unless otherwise explicitly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.

[0028] Please see Figure 1 , Figure 2 and Figure 3 This application provides an unpacking device 100, which is applied to a packaging box 200. Specifically, the unpacking device 100 is used to open the packaging box 200 (see reference 200) in a folded state. Figure 2 ) Open to obtain a three-dimensional packaging box 200 (reference) Figure 3 The packaging box 200 is roughly flat in its folded state, and has a top plate 21 and a bottom plate 22 that are offset from each other in the folded state. It should be noted that the top plate 21 refers to the top plate-like structure of the packaging box 200 in the folded state, and the bottom plate 22 refers to the bottom plate-like structure of the packaging box 200 in the folded state. "Offset" means that when the packaging box 200 is folded and placed horizontally, the projections of the top plate 21 and the bottom plate 22 in the vertical direction do not completely coincide.

[0029] Please see Figure 1 ,Figure 2 and Figure 3 The unpacking device 100 includes a bracket 10, a first connecting mechanism 11, a second connecting mechanism 12, a first moving mechanism 13, and a second moving mechanism 14. The bracket 10 is the main frame structure of the unpacking device 100, used to connect and install other mechanisms and parts of the unpacking device 100. The first connecting mechanism 11 is used to connect to the top plate 21 of the packaging box 200 in its folded state (see reference). Figure 2 The first connecting mechanism 11 is connected to the bottom plate 22 of the folded packaging box 200 to complete the opening operation. It should be noted that the connection between the first connecting mechanism 11 and the top plate 21 is a detachable fixed connection; that is, when the first connecting mechanism 11 is connected to the top plate 21, the two are relatively fixed, and the first connecting mechanism 11 can also be separated from the top plate 21. Similarly, the connection between the second connecting mechanism 12 and the bottom plate 22 is a detachable fixed connection; that is, when the second connecting mechanism 12 is connected to the bottom plate 22, the two are relatively fixed, and the second connecting mechanism 12 can also be separated from the bottom plate 22. A first moving mechanism 13 is disposed on the bracket 10 and connected to the first connecting mechanism 11. The first moving mechanism 13 is used to drive the first connecting mechanism 11 to move along the first direction X to complete the opening operation. The second moving mechanism 14 is disposed on the bracket 10 and connected to the second connecting mechanism 12. The second moving mechanism 14 is used to drive the second connecting mechanism 12 to move along the second direction Y to complete the unpacking operation. The second direction Y is perpendicular to the first direction X. It should be noted that the first direction X and the second direction Y can be any two mutually perpendicular directions. However, in the actual use scenario of the unpacking device 100, the unpacking device 100 is usually placed on a horizontal plane. At this time, the first direction X is the vertical direction and the second direction Y is the horizontal direction.

[0030] When the aforementioned unpacking device 100 is in operation, the first connecting mechanism 11 is connected to the top plate 21 of the folded packaging box 200, and the second connecting mechanism 12 is connected to the bottom plate 22 of the folded packaging box 200. Then, the first moving mechanism 13 and the second moving mechanism 14 are activated simultaneously. The first moving mechanism 13 drives the first connecting mechanism 11 to move the top plate 21 away from the bottom plate 22 along the first direction X. The second moving mechanism 14 drives the second connecting mechanism 12 to move the bottom plate 22 towards the top plate 21 along the second direction Y. The first moving mechanism 13 and the second moving mechanism 14 stop when the bottom plate 22 moves to the position corresponding to the top plate 21. At this time, the packaging box 200 is fully opened and fixed, and the entire unpacking process ends. In summary, the above-mentioned box opening device 100 can automatically open the packaging box 200 in a folded state, and can immediately fix the packaging box 200 in an open state after the opening operation is completed. Therefore, the above-mentioned box opening device 100 has the beneficial effects of high box opening efficiency, saving manpower, and being able to fix the packaging box 200 immediately after opening.

[0031] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, the support 10 includes a first guide rail 101 extending along a first direction X. The first guide rail 101 is at least a partial structure of the support 10. The first connecting mechanism 11 includes a first connecting component 111 and a first mounting component 112 connected together. The first connecting component 111 is a part of the first connecting mechanism 11 for connecting with the top plate 21 of the packaging box 200 in a folded state, and is disposed on the first mounting component 112. The first mounting component 112 is movably disposed on the first guide rail 101. The first connecting component 111 is used to connect to the top plate 21 of the packaging box 200 in a folded state. A first moving mechanism 13 is disposed on the first guide rail 101 and connected to the first mounting component 112 for driving the first mounting component 112 and the first connecting component 111 to move synchronously along the first direction X.

[0032] With the above settings, when the unpacking device 100 is working, the first connecting component 111 is connected to the top plate 21 of the folded packaging box 200, and the first moving mechanism 13 drives the first mounting component 112 and the first connecting component 111 to move synchronously along the first direction X away from the bottom plate 22 of the folded packaging box 200, thereby completing some of the actions required to open the packaging box 200.

[0033] In some embodiments, the first moving mechanism 13 includes a drive motor 131 and a ball screw 132. The ball screw 132 includes a screw 1321 and a nut seat 1322 disposed on the screw 1321. The screw 1321 is disposed on the bracket 10 along a first direction X, and the screw 1321 is rotatably connected to the bracket 10. The drive motor 131 is connected to the screw 1321 to drive the screw 1321 to rotate. The nut seat 1322 is threaded onto the screw 1321 and is connected to the first mounting assembly 112. As a specific example, in this embodiment, the output shaft of the drive motor 131 and the screw 1321 are connected by a drive wheel 133, a driven wheel 134, and a timing belt 135. Specifically, the drive wheel 133 is coaxially connected to the output shaft of the drive motor 131, the driven wheel 134 is coaxially connected to the screw 1321 and is coplanar with the drive wheel 133, and the timing belt 135 is sleeved between the drive wheel 133 and the driven wheel 134. Therefore, when the output shaft of the drive motor 131 rotates, the screw 1321 will also be driven to rotate, thereby driving the nut seat 1322 to move synchronously in the first direction X along the first mounting assembly 112 and the first connecting assembly 111. By controlling the forward and reverse rotation of the drive motor 131, the direction of movement of the nut seat 1322 can be changed. In other embodiments, the output shaft of the drive motor 131 may be directly coaxially connected to the screw 1321, or the transmission connection with the screw 1321 may be achieved through gear meshing. This embodiment does not limit the specific connection form between the output shaft of the drive motor 131 and the screw 1321.

[0034] With the above settings, when the unpacking device 100 is working, the first connecting component 111 is connected to the top plate 21 of the folded packaging box 200, and the drive motor 131 drives the screw 1321 to rotate, so that the nut seat 1322 drives the first mounting component 112 and the first connecting component 111 to move synchronously along the first direction X away from the bottom plate 22 of the folded packaging box 200, thereby completing some of the actions required to open the packaging box 200.

[0035] In some other embodiments, the first moving mechanism 13 may also be a rodless cylinder or a conventional cylinder connected to the first mounting assembly 112 along the first direction X. The first moving mechanism 13 can directly drive the first mounting assembly 112 and the first connecting assembly 111 to move synchronously along the first direction X. This embodiment does not limit the specific structure and type of the first moving mechanism 13.

[0036] Please see Figure 1 , Figure 2 and Figure 5In some embodiments, the first connecting assembly 111 includes a connected first suction cup 1111 and a first vacuum generator (not shown in the figure). The first suction cup 1111 is used to directly contact the top plate 21 of the packaging box 200 in the folded state, and the first vacuum generator is used to create a negative pressure environment within the first suction cup 1111 so that the first suction cup 1111 adsorbs the top plate 21 to achieve the connection between the first suction cup 1111 and the top plate 21. The first mounting assembly 112 includes a connected first mounting plate 1121 and a first mounting bracket 1122. The first mounting plate 1121 is generally flat and is substantially perpendicular to the first direction X. The first mounting bracket 1122 is a specific structure for mounting the first suction cup 1111. The first suction cup 1111 is connected to the first mounting bracket 1122, and the first mounting plate 1121 is connected to the nut seat 1322.

[0037] With the above settings, when the box opening device 100 is working, the first moving mechanism 13 first drives the first connecting mechanism 11 to move, so that the first suction cup 1111 contacts the top plate 21 of the folded packaging box 200. Then, the first vacuum generator forms a negative pressure inside the first suction cup 1111 to achieve the connection between the first suction cup 1111 and the top plate 21, so that the opening operation of the packaging box 200 can continue.

[0038] In some other embodiments, the first connecting component 111 may also be any kind of component such as a mechanical gripper, a magnetic component (used to open the packaging box 200 made of magnetic material), as long as it can achieve connection with the top plate 21 of the packaging box 200 in the folded state.

[0039] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, multiple sets of the first suction cup 1111 and the first mounting bracket 1122 can be correspondingly arranged. For example, in this embodiment, four sets of the first suction cup 1111 and the first mounting bracket 1122 are correspondingly arranged, with the four first suction cups 1111 respectively corresponding to the four corners of the top plate 21, which can improve the stability and reliability of the first suction cup 1111 adhering to the top plate 21. In other embodiments, the first suction cup 1111 and the first mounting bracket 1122 can also be correspondingly arranged in one, two, three, five, or any number of sets. This embodiment does not limit the number of the first suction cup 1111 and the first mounting bracket 1122.

[0040] In some embodiments, the first mounting plate 1121 is provided with a first mounting groove 1123 extending along the second direction Y. The first mounting bracket 1122 is connected to the first mounting plate 1121 by fasteners such as bolts and nuts and is embedded in the first mounting groove 1123. The first mounting bracket 1122 can move along the extension direction of the first mounting groove 1123 (i.e., the second direction Y) to adjust the position of the first mounting bracket 1122 and the first suction cup 1111. The first mounting bracket 1122 is also provided with a first mounting hole 1124 extending along a third direction Z. The third direction Z is perpendicular to the first direction X and intersects the second direction Y. The first suction cup 1111 is connected to the first mounting bracket 1122 by fasteners such as bolts and nuts and passes through the first mounting hole 1124. The first suction cup 1111 can move along the extension direction of the first mounting hole 1124 (i.e., the third direction Z) to change its relative position with the first mounting bracket 1122.

[0041] With the above settings, the operator can adjust the position of the first mounting bracket 1122 relative to the first mounting plate 1121 along the second direction Y, and can also adjust the position of the first suction cup 1111 relative to the first mounting bracket 1122 along the third direction Z. Therefore, the relative positions of multiple first suction cups 1111 can be adjusted so that the first suction cups 1111 can adsorb the top plate 21 of packaging boxes 200 of different sizes, so that the first connecting mechanism 11 can be adapted to packaging boxes 200 of different sizes.

[0042] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 In some embodiments, the bracket 10 further includes a second guide rail 102 extending along the second direction Y. The second guide rail 102 is at least a part of the structure of the bracket 10. The second guide rail 102 is connected to the first guide rail 101, and the second guide rail 102 and the first guide rail 101 may be integrally formed, welded, or fixedly connected by fasteners such as bolts. The second connecting mechanism 12 includes a connected second connecting component 121 and a second mounting component 122. The second connecting component 121 is a component of the second connecting mechanism 12 used to connect with the bottom plate 22 of the packaging box 200 in the folded state, and it is disposed on the second mounting component 122. The second mounting component 122 is movably disposed on the second guide rail 102. The second connecting component 121 is used to connect to the bottom plate 22 of the packaging box 200 in the folded state. The second moving mechanism 14 is disposed on the second guide rail 102 and connected to the second mounting component 122 to drive the second mounting component 122 and the second connecting component 121 to move synchronously along the second direction Y.

[0043] With the above settings, when the unpacking device 100 is working, the second connecting component 121 is connected to the bottom plate 22 of the folded packaging box 200, and the second moving mechanism 14 drives the second mounting component 122 and the second connecting component 121 to move synchronously along the second direction Y toward the top plate 21 of the folded packaging box 200, thereby completing some of the actions required to open the packaging box 200.

[0044] In some embodiments, the second moving mechanism 14 includes a rodless cylinder 141, which includes a cylinder barrel 1411 and a cylinder slider 1412. The cylinder barrel 1411 is disposed on the bracket 10 along the second direction Y, and the cylinder slider 1412 is slidably disposed on the cylinder barrel 1411. The cylinder slider 1412 is connected to the second mounting assembly 122. The cylinder slider 1412 can drive the second mounting assembly 122 and the second connecting assembly 121 to move along the extension direction of the cylinder barrel 1411 (i.e., the second direction Y).

[0045] With the above settings, when the box opening device 100 is working, the second connecting component 121 is connected to the bottom plate 22 of the folded packaging box 200, and the cylinder slider 1412 of the rodless cylinder 141 can drive the second mounting component 122 and the second connecting component 121 to move synchronously along the second direction Y toward the top plate 21 of the folded packaging box 200, thereby completing some of the actions required to open the packaging box 200.

[0046] In other embodiments, the second moving mechanism 14 may be a conventional cylinder connected to the second mounting assembly 122 and arranged along the second direction Y. Alternatively, the second moving mechanism 14 may include a drive motor and a ball screw, with the drive motor driving the screw of the ball screw to rotate, thereby driving the nut seat on the screw to move the second mounting assembly and the second connecting assembly synchronously along the second direction Y. This embodiment does not limit the specific structure and type of the second moving mechanism 14.

[0047] Please see Figure 1 , Figure 2 and Figure 6In some embodiments, the second connecting assembly 121 includes a connected second suction cup 1211 and a second vacuum generator (not shown in the figure). The second suction cup 1211 is used to directly contact the bottom plate 22 of the packaging box 200 in the folded state, and the second vacuum generator is used to create a negative pressure environment within the second suction cup 1211 so that the second suction cup 1211 adsorbs the bottom plate 22 to achieve the connection between the second suction cup 1211 and the bottom plate 22. The second mounting assembly 122 includes a connected second mounting plate 1221 and a second mounting bracket 1222. The second mounting plate 1221 is generally flat and is substantially perpendicular to the first direction X. The second mounting bracket 1222 is a specific structure for mounting the second suction cup 1211. The second suction cup 1211 is connected to the second mounting bracket 1222, and the second mounting plate 1221 is connected to the cylinder slider 1412.

[0048] With the above settings, when the box opening device 100 is working, the folded packaging box 200 is first placed on the second suction cup 1211 so that the second suction cup 1211 contacts the bottom plate 22 of the folded packaging box 200. Then, the second vacuum generator creates a negative pressure inside the second suction cup 1211 to achieve the connection between the second suction cup 1211 and the bottom plate 22, so that the opening operation of the packaging box 200 can be continued.

[0049] In some other embodiments, the second connecting component 121 may also be any kind of component such as a mechanical gripper, a magnetic component (used to open the packaging box 200 made of magnetic material), as long as it can achieve connection with the bottom plate 22 of the packaging box 200 in the folded state.

[0050] Please see Figure 1 , Figure 2 and Figure 6 In some embodiments, multiple sets of the second suction cup 1211 and the second mounting bracket 1222 can be correspondingly provided. For example, in this embodiment, four sets of the second suction cup 1211 and the second mounting bracket 1222 are correspondingly provided, with the four second suction cups 1211 corresponding to the four corners of the base plate 22, which can improve the stability and reliability of the second suction cup 1211 adhering to the base plate 22. In other embodiments, the second suction cup 1211 and the second mounting bracket 1222 can also be correspondingly provided in any number of sets, such as one, two, three, or five sets. This embodiment does not limit the number of the second suction cup 1211 and the second mounting bracket 1222.

[0051] In some embodiments, the second mounting plate 1221 is provided with a second mounting groove 1223 extending along the second direction Y. The second mounting bracket 1222 is connected to the second mounting plate 1221 by fasteners such as bolts and nuts and is embedded in the second mounting groove 1223. The second mounting bracket 1222 can move along the extension direction of the second mounting groove 1223 (i.e., the second direction Y) to adjust the position of the second mounting bracket 1222 and the second suction cup 1211. The second mounting bracket 1222 is also provided with a second mounting hole 1224 extending along a third direction Z. The third direction Z is perpendicular to the first direction X and intersects the second direction Y. The second suction cup 1211 is connected to the second mounting bracket 1222 by fasteners such as bolts and nuts and passes through the second mounting hole 1224. The second suction cup 1211 can move along the extension direction of the second mounting hole 1224 (i.e., the third direction Z) to change its relative position with the second mounting bracket 1222.

[0052] With the above settings, the operator can adjust the position of the second mounting bracket 1222 relative to the second mounting plate 1221 along the second direction Y, and can also adjust the position of the second suction cup 1211 relative to the second mounting bracket 1222 along the third direction Z. Therefore, the relative positions of multiple second suction cups 1211 can be adjusted so that the second suction cups 1211 can adsorb the bottom plate 22 of packaging boxes 200 of different sizes, so that the second connecting mechanism 12 can be adapted to packaging boxes 200 of different sizes, and then the box opening device 100 can open packaging boxes 200 of different sizes in a folded state.

[0053] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6In some embodiments, the unpacking device 100 further includes a first guiding mechanism 15 and a second guiding mechanism 16. The first guiding mechanism 15 is disposed on the first guide rail 101 of the bracket 10 along the first direction X to guide the first connecting mechanism 11 along the first direction X. The second guiding mechanism 16 is disposed on the second guide rail 102 of the bracket 10 along the second direction Y to guide the second connecting mechanism 12 along the second direction Y. The first guiding mechanism 15 includes a first guiding member 151 and a first movable member 152. The first guiding member 151 is disposed on the bracket 10 (specifically on the first guide rail 101) along the first direction X. The first movable member 152 is movably connected to the first guiding member 151 and is connected to the first connecting mechanism 11. The second guiding mechanism 16 includes a second guide member 161 and a second movable member 162. The second guide member 161 is disposed on the bracket 10 (specifically on the second guide rail bracket 102) along the second direction Y. The second movable member 162 is movably connected to the second guide member 161 and is connected to the second connecting mechanism 12. As a specific example, in this embodiment, both the first guide member 151 and the second guide member 161 are guide rails, the first movable member 152 is a slider slidably disposed on the first guide member 151, and the second movable member 162 is a slider slidably disposed on the second guide member 161. In other embodiments, the first guide 151 and the second guide 161 can also be guide grooves, the first movable member 152 can be a guide slider embedded in the first guide 151, and the second movable member 162 can be a guide slider embedded in the second guide 161; alternatively, the first guide 151 and the second guide 161 can also be fixed slide rails, the first movable member 152 is a movable slide rail slidably disposed on the first guide 151, and the second movable member 162 is a movable slide rail slidably disposed on the second guide 161. The first guide 151 and the second guide 161 can be of the same or different types, and the first movable member 152 and the second movable member 162 can be of the same or different types.

[0054] In some embodiments, multiple first guide mechanisms 15 and multiple second guide mechanisms 16 may be provided. For example, in this embodiment, two first guide mechanisms 15 are provided, and the two first guide mechanisms 15 are arranged relatively apart, which can improve the guiding effect of the first guide mechanisms 15 on the movement of the first connecting mechanism 11 and the first moving mechanism 13; two second guide mechanisms 16 are also provided, and the two second guide mechanisms 16 are arranged relatively apart, which can improve the guiding effect of the second guide mechanisms 16 on the movement of the second connecting mechanism 12 and the second moving mechanism 14. In other embodiments, one, three, four, or any number of first guide mechanisms 15 and two second guide mechanisms 16 may be provided, and the number of first guide mechanisms 15 and second guide mechanisms 16 may be the same or different.

[0055] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, the first guide mechanism 15 further includes at least two first limiting members 153. The at least two first limiting members 153 are respectively distributed at both ends of the first guide member 151, and both first limiting members 153 are located on the movement path of the first movable member 152 to engage with the first movable member 152, thereby limiting the movement range of the first movable member 152 on the first guide member 151. As a specific example, in this embodiment, the first limiting member 153 is a block structure, and two first limiting members 153 are provided in each first guide mechanism 15. Both first limiting members 153 are connected to the bracket 10 (specifically the first guide rail bracket 101) and are respectively distributed at both ends of the first limiting member 153. When the first movable member 152 moves to the position of the first limiting member 153, the first limiting member 153 can engage with the first movable member 152 to prevent the first movable member 152 from continuing to move, thereby limiting the movement range of the first movable member 152 and the first connecting mechanism 11 in the first direction X. In other embodiments, the first limiting member 153 can also be a rod-shaped structure, a strip-shaped structure or any other shape. The first limiting member 153 can also be provided in any number of three, four, five or so. The first limiting member 153 can also be provided on the first guide member 151, as long as the first limiting member 153 is provided at both ends of the first guide member 151 and can be engaged with the first movable member 152.

[0056] The second guide mechanism 16 further includes at least two second limiting members 163. The at least two second limiting members 163 are respectively distributed at both ends of the second guide member 161, and are located on the movement path of the second movable member 162 to engage with it, thereby limiting the movement range of the second movable member 162 on the second guide member 161. As a specific example, in this embodiment, the second limiting member 163 is a block structure, and each second guide mechanism 16 has two second limiting members 163. Both second limiting members 163 are connected to the bracket 10 (specifically the second guide rail bracket 102) and are respectively distributed at both ends of the second limiting member 163. When the second movable member 162 moves to the position of the second limiting member 163, the second limiting member 163 can engage with the second movable member 162 to prevent it from continuing to move, thereby limiting the movement range of the second movable member 162 and the second connecting mechanism 12 in the second direction Y. In other embodiments, the second limiting member 163 can also be a rod-shaped structure, a strip-shaped structure or any other shape. The second limiting member 163 can also be provided in any number of three, four, five or so. The second limiting member 163 can also be provided on the second guide member 161, as long as the second limiting member 163 is provided at both ends of the second guide member 161 and can be engaged with the second movable member 162.

[0057] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The unpacking device 100 also includes a shaping base 17, which is connected to the first connecting mechanism 11 and is used to shape and fix the opened packaging box 200 after it is fully opened. The shaping base 17 includes a limiting plate 171 and a pressing plate 172, both of which are generally plate-shaped. The limiting plate 171 is connected to the first connecting mechanism 11, specifically to the first mounting plate 1121. The limiting plate 171 is perpendicular to the second direction Y. The pressing plate 172 is connected to the limiting plate 171 and is perpendicular to it. The pressing plate 172 is located on the side of the limiting plate 171 away from the bracket 10. When the first connecting mechanism 11 is in contact with the top plate 21 of the folded packaging box 200, the limiting plate 171 is in contact with the folded packaging box 200, and the pressing plate 172 is in contact with the top plate 21 of the folded packaging box 200.

[0058] With the above configuration, when the unpacking device 100 is working, the first moving mechanism 13 drives the first connecting mechanism 11 and the top plate 21 to move away from the bottom plate 22 along the first direction X, and the second moving mechanism 14 drives the second connecting mechanism 12 and the bottom plate 22 to move closer to the top plate 21 along the second reverse direction Y. During the above process, the pressing plate 172 is always in contact with the top plate 21. As the packaging box 200 is continuously opened, a side plate of the packaging box 200 located between the top plate 21 and the bottom plate 22 and close to the limiting plate 171 will continuously move closer to the limiting plate 171 until the side plate is in contact with the limiting plate 171. Since the top plate 21 and the pressing plate 172 are always in contact, and the pressing plate 172 and the limiting plate 171 are set perpendicularly, the side plate is also perpendicular to the top plate 21 of the packaging box 200 at this time, and the packaging box 200 is in a fully open state (see reference). Figure 3 Furthermore, because the clamping plate 172 and the limiting plate 171 jointly compress the fully opened packaging box 200, the fully opened packaging box 200 can be shaped and fixed. In summary, the above-mentioned box opening device 100 can not only automatically open the packaging box 200 in a folded state, but also immediately shape and fix the opened packaging box 200 after the opening operation is completed, thereby greatly improving the opening efficiency and shaping efficiency of the packaging box 200, and facilitating the batch processing of the packaging box 200.
