[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the present application, not all the implementation modes. Based on the implementation mode in the present application, all other implementation modes obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0029] See also Figure 1 , a box opening device 10 provided in an embodiment of the present application, comprises a bracket 100 and an unfolding and forming mechanism 200, wherein the unfolding and forming mechanism 200 is mounted on the bracket 100. The unfolding and forming mechanism 200 is used to unfold a packaging box 5 in a folded state, and to restrict the unfolded packaging box 5 from detaching from the bracket 100 and restoring the unfolded shape.

[0030] See also Figure 2 The bracket 100 is provided with a box body cavity 110 and a cavity inlet and outlet 115, so that the packaging box 5 enters the box body cavity 110 from the cavity inlet and outlet 115. The shape and size of the box body cavity 110 are consistent with the packaging box 5, so that the packaging box 5 can enter the box body cavity 110, and the box body cavity 110 is used to position the packaging box 5. The bracket 100 is provided with a notch 120, and the notch 120 is opposite to the cavity inlet and outlet 115. The bracket 100 has a limiting surface 125, and the limiting surface 125 surrounds the notch 120, and the limiting surface 125 is arc-shaped. Such a setting allows the limiting surface 125 to guide the deformation of the opening of the packaging box 5, and the edge of the box opening fits the limiting surface 125, so that the width of the box opening is increased, so that in the subsequent material entry operation, the material can enter the packaging box 5 more conveniently.

[0031] The unfolding and forming mechanism 200 includes a box unfolding and forming member 210 and a box shaping assembly 220. The box unfolding and forming member 210 is located at the cavity inlet and outlet 115 and is suitable for guiding the packaging box 5 to unfold and form. After passing through the box unfolding and forming member 210, the packaging box 5 is unfolded and formed and enters the box cavity 110 through the cavity inlet and outlet 115 and is positioned in the box cavity 110. In one embodiment, the box unfolding and forming member 210 has an arc surface 2101, and the arc center of the arc surface 2101 is located on the side of the arc surface 2101 away from the cavity inlet and outlet 115. When the packaging box 5 passes through the box unfolding and forming member 210, the arc surface 2101 of the box unfolding and forming member 210 guides the packaging box 5 to be formed along the fold of the packaging box 5.

[0032] In one embodiment, the box body unfolding forming member 210 may include a plurality of forming blocks, and the plurality of forming blocks are arranged on the bracket 100 corresponding to the packaging box 5, so that when the packaging box 5 passes through the forming blocks, the forming blocks squeeze the unexpanded packaging box 5, so that the packaging box 5 is unfolded into a desired shape according to the designed folds. The forming blocks are arranged on both sides of the bracket 100, and the forming blocks may have different heights. A clearance position 105 may be reserved between the forming blocks in the horizontal direction of the bracket 100, which helps to avoid obstruction to other structures of the box opening device 10, for example, the box taking mechanism 400 of the box opening device 10 may pass through the clearance position 105 when driving the packaging box 5 to move.

[0033] In one embodiment, the box body shaping component 220 has a box body separation state and a box body abutment state. When the packaging box 5 enters the box body cavity 110 from the cavity inlet and outlet 115 and is positioned in the box body cavity 110, the box body shaping component 220 is in the box body abutment state. The box body shaping component 220 in the box body abutment state is suitable for abutting against the packaging box 5 located in the box body cavity 110 to limit the packaging box 5 from the cavity inlet and outlet 115 to separate from the box body cavity 110. The box body shaping component 220 can abut against the packaging box 5 from different directions and apply forces to the packaging box 5 from different directions to position and limit the packaging box 5 to the box body cavity 110 to prevent the packaging box 5 from returning to an unexpanded shape.

[0034] The box body shaping component 220 in the box body separation state is suitable for being spaced apart from the packaging box 5. Before the packaging box 5 has not completely entered the box body cavity 110 and is positioned in the box body cavity 110, the box body shaping component 220 is in the box body separation state, and the box body shaping component 220 is not in contact with the packaging box 5. After the packaging box 5 is loaded with products, the box body shaping component 220 can be in the box body separation state to be spaced apart from the packaging box. At this time, the box body shaping component 220 does not abut against the packaging box 5, which is convenient for the packaging box to proceed to the next process.

[0035] See also Figure 3In one embodiment, the box shaping component 220 includes a first abutting unit 2210, which is installed on the box unfolding molding 210. The first abutting unit 2210 can be installed above the box unfolding molding 210 or below the box unfolding molding 210. In one embodiment, the height of the box unfolding molding 210 is less than the height of the packaging box 5, so that the first abutting unit 2210 can abut against the packaging box 5. In one embodiment, the packaging box 5 includes adjacent first and second surfaces 501 and 502. The first surface 501 is the surface of the packaging box 5 facing the cavity inlet and outlet 115, and the first abutting unit 2210 abuts against the first surface 501 of the packaging box 5.

[0036] When the box body shaping component 220 is in the box body abutting state, the first abutting unit 2210 presses against the packaging box 5 along the first direction D1, and the first direction D1 is the direction from the cavity inlet and outlet 115 toward the box body cavity 110. The first direction D1 corresponds to the first surface 501 of the packaging box 5, and the first abutting unit 2210 abuts against the first surface 501 of the packaging box 5, and a force is applied to the first surface 501 of the packaging box 5, and the direction of the force is from the cavity inlet and outlet 115 to the box body cavity 110, so as to limit the packaging box 5 from being separated from the box body cavity 110.

[0037] See also Figure 4 In one embodiment, the first abutment unit 2210 includes a first abutment member 2211 and a first main body 2212. The first abutment member 2211 is telescopically mounted on the first main body 2212. The shape of the first main body 2212 may be the same as the cross-sectional shape of the box body unfolding molding member 210. The edge of the first main body 2212 may be flush with the edge of the arc surface 2101 of the box body unfolding molding member 210, so that when the packaging box 5 passes through the box body unfolding molding member 210, the first abutment member 2211 may guide the packaging box 5 to be formed together with the box body unfolding molding member 210, and the first abutment member 2211 plays a role in assisting the box body to be formed in this process.

[0038] In one embodiment, the first main body 2212 includes a shell 2201 and an elastic member 2202, the shell 2201 is provided with a shell accommodating space 2203, the first counter member 2211 is rotatably installed on the shell 2201, the first counter member 2211 can be selectively rotated relative to the shell 2201 to the shell accommodating space 2203 or protrude out of the shell accommodating space 2203, the elastic member 2202 is connected between the shell 2201 and the first counter member 2211, and in the process of the packaging box 5 unfolding the forming member 210 through the box body, due to the interaction between the first counter unit 2210 and the packaging box 5, the first counter member 2211 can be squeezed into the shell accommodating space 2203 under the action of the second surface 502 of the packaging box 5 until it is completely accommodated by the shell accommodating space 2203. After the packaging box 5 passes through the box body unfolding molding 210 and is positioned in the box body cavity 110, the second surface 502 of the packaging box 5 no longer acts on the first abutting unit 2210, and the elastic force of the elastic member 2202 drives the first abutting member 2211 to rotate to protrude out of the shell receiving space 2203. The setting of the elastic member 2202 allows the first abutting unit 2210 to be retracted into the shell receiving space 2203 under the action of the second surface 502 of the packaging box 5, which helps the packaging box 5 to smoothly enter the box body cavity 110 from the cavity inlet and outlet 115; at the same time, after the packaging box 5 enters the box body cavity 110, the first abutting member 2211 can automatically pop out to abut against the packaging box 5, thereby limiting the packaging box 5 from leaving the box body cavity 110 from the cavity inlet and outlet 115.

[0039] When the packaging box 5 is positioned in the box body cavity 110, the box body shaping component 220 is in a box body abutting state, the first abutting member 2211 protrudes out of the shell accommodating space 2203, the first abutting member 2211 is protruded outside the first main body 2212 and abuts against the first surface 501 of the packaging box 5 facing the cavity inlet and outlet 115, and in the process of the packaging box 5 passing through the box body unfolding molding member 210, the direction of the action of the packaging box 5 on the first abutting member 2211 is perpendicular to the direction in which the first abutting member 2211 abuts against the packaging box 5 when the box body shaping component 220 is in a box body abutting state.

[0040] See also Figure 5 In one embodiment, the box body shaping component 220 includes a second abutting unit 2220, and the second abutting unit 2220 is installed on the bracket 100. When the box body shaping component 220 is in the box body abutting state, the second abutting unit 2220 presses against the packaging box 5 along the second direction D2, and the second direction D2 is perpendicular to the first direction D1. In one embodiment, the second abutting unit 2220 is installed on the left or right side of the bracket 100, and the second abutting unit 2220 is staggered with the avoidance position 105. When the box body shaping component 220 is in the box body abutting state, the second abutting unit 2220 can press against the packaging box 5 from the second surface 502 of the packaging box 5.

[0041] When the second abutting unit 2220 cooperates with other box shaping components 220 such as the first abutting unit 2210, the second abutting unit 2220 and the first abutting unit 2210 are pressed against different surfaces of the packaging box 5. The second unit 2220 can not only act on the packaging box 5 from different surfaces to maintain the unfolded shape of the packaging box 5, but also because the action directions of the first abutting unit 2210 and the second abutting unit 2220 are perpendicular, the second abutting unit 2220 can increase the friction force of the first abutting unit 2210 on the packaging box 5 to maintain the unfolded shape of the packaging box 5 and limit the packaging box 5 from detaching from the box body cavity 110. In one embodiment, the setting of the box shaping component 220 can be selected according to the actual application, and different abutting units can be flexibly selected to achieve a better shaping effect on the packaging box 5.

[0042] The second abutting unit 2220 includes a second abutting member 2221 and a second main body 2222 connected to each other. The second main body 2222 drives the second abutting member 2221 to slide back and forth. When the second main body 2222 of the second abutting unit 2220 drives the second abutting member 2221 to abut against the packaging box 5, the box body shaping assembly 220 is in a box body abutting state, and the second abutting member 2221 abuts against the second surface 502. In one embodiment, the second main body 2222 is a linear cylinder, the cylinder barrel of the second main body 2222 is mounted on the bracket 100, and the piston rod of the second main body 2222 is connected to the second abutting member 2221.

[0043] See also Figure 3 In one embodiment, the box body shaping component 220 also includes a third abutting unit 2230, and the third abutting unit 2230 is installed on the bracket 100. When the box body shaping component 220 is in the box body abutting state, the third abutting unit 2230 presses against the packaging box 5 along the first direction D1, and the third abutting unit 2230 abuts against the first surface 501 of the packaging box 5. The third abutting unit 2230 and the first abutting unit 2210 are staggered, and the third abutting unit 2230 and the first abutting unit 2210 respectively abut at different positions of the first surface 501 of the packaging box 5.

[0044] In one embodiment, when the box body shaping component 220 is in a box body abutting state, the third abutting unit 2230 has a larger contact area with the packaging box 5 than the first abutting unit 2210, so that the third abutting unit 2230 can press the first surface 501 of the packaging box 5 more directly and effectively in the D1 direction, so that the packaging box 5 fits tightly with the box body cavity 110 to prevent the packaging box 5 from detaching from the box body cavity 110.

[0045] In one embodiment, the setting of the box body shaping component 220 can be selected according to the actual application, and different offset units can be flexibly selected to achieve a better shaping effect on the packaging box 5. The first offset unit 2210, the second offset unit 2220, and the third offset unit 2230 of the box body shaping component 220 can act alone or in combination to achieve the effect of maintaining the unfolded shape of the packaging box 5 and limiting the packaging box 5 from detaching from the box body cavity 110.

[0046] In one embodiment, the third offset unit 2230 includes a third offset member 2231 and a third main body 2232 connected to each other. The third main body 2232 drives the third offset member 2231 to rotate reciprocatingly. When the third main body 2232 drives the third offset member 2231 to offset against the packaging box 5, the box body shaping assembly 220 is in a box body offset state, and the third offset member 2231 offsets against the surface of the packaging box 5 facing the cavity inlet and outlet 115.

[0047] In one embodiment, the third body 2232 includes a rotary drive member 2233 and a connecting member 2234, and the rotary drive member 2233 is installed on the bracket 100. The rotary drive member 2233 can be a structure such as a cylinder or a motor. The connecting member 2234 is connected between the output shaft of the rotary drive member 2233 and the third abutting member 2231, and the third abutting member 2231 deviates from the axis of the output shaft of the rotary drive member 2233. The rotary drive member 2233 drives the connecting member 2234 and the third abutting member 2231 to reciprocate, and the range of rotation is greater than 90°. The end point of the reciprocating rotation of the connecting member 2234 and the third abutting member 2231 abuts against the first surface 501 of the packaging box 5. Such an arrangement makes the third abutting member 2231 not cause obstacles to the unfolding and forming of the packaging box 5 and the entry of the packaging box 5 from the cavity inlet and outlet 115 into the box body cavity 110 during the reciprocating rotation process.

[0048] See also Figure 5 In one embodiment, the box opening device 10 further includes a processor (not shown) and a box opening detection sensor 205. The box opening detection sensor 205 is disposed on the bracket 100. The box opening detection sensor 205 is disposed corresponding to the box body cavity 110, so that the box opening detection sensor 205 can detect that the packaging box 5 that is not fully unfolded is partially blocked in the length direction, such as the second direction D2.

[0049] The processor is electrically connected to the box opening detection sensor 205 and the box body shaping component 220. When the packaging box 5 fails to be fully unfolded and formed, the processor can receive the detection signal of the box opening detection sensor 205 and control the box body shaping component 220 to change to the box body abutting state according to the detection signal.

[0050] When the packaging box 5 is fully unfolded and formed, the box opening detection sensor 205 is not blocked in the length direction, such as the second direction D2. The processor can receive the detection signal of the box opening detection sensor 205 and control the box body qualitative component 220 to change to the box body separation state according to the detection signal.

[0051] See also Figure 6 In one embodiment, the box opening device 10 also includes a box supply mechanism 300 and a box taking mechanism 400. The unfolding and molding mechanism 200 is located between the box supply mechanism 300 and the bracket 100. The box taking mechanism 400 is suitable for driving the packaging box 5 located in the box supply mechanism 300 to enter the box body cavity 110 from the cavity inlet and outlet 115 through the box body unfolding molding part 210. The box taking mechanism 400 moves within the range of the bracket 100 via the avoidance position 105.

[0052] In one embodiment, the processor is electrically connected to the box taking mechanism 400 . When the packaging box 5 fails to be fully unfolded, upon receiving a detection signal from the box opening detection sensor 205 , the processor can control the box taking mechanism 400 to redirect the packaging box 5 to be positioned in the box body cavity 110 from the first direction D1 .

[0053] The box opening device 10 provided in the embodiment of the present application includes a bracket 100 and an unfolding and forming mechanism 200, the bracket 100 is provided with a box body cavity 110 and a cavity inlet and outlet 115, the unfolding and forming mechanism 200 is installed on the bracket 100, the unfolding and forming mechanism 200 is located at the cavity inlet and outlet 115 and is suitable for guiding the packaging box 5 to unfold and form, so that the automated forming of the packaging box 5 is more efficient and convenient. The unexpanded packaging box 5 is unfolded and formed after passing through the unfolding and forming mechanism 200, and then enters the box body cavity 110 from the cavity inlet and outlet 115. The unfolding and forming mechanism 200 includes a box body unfolding and forming member 210 and a box body shaping component 220, and the box body shaping component 220 is used to maintain the unfolding and forming state of the packaging box 5, so as to prevent the packaging box 5 from restoring the unexpanded shape before loading the product. The box body shaping component 220 has a box body separation state and a box body counter state. When the packaging box 5 has not yet entered the box body cavity 110, the box body shaping component 220 is in a box body separation state and is spaced from the packaging box 5. After the packaging box 5 enters the box body cavity 110 from the self-cavity inlet and outlet 115, the box body shaping component 220 is in a box body abutting state, abutting against the packaging box 5, and the packaging box 5 is fixed to the box body cavity 110 and maintains an expanded molding state, preventing the packaging box 5 from escaping from the box body cavity 110 from the self-cavity inlet and outlet 115, avoiding the failure of the product entering the box caused by the packaging box 5 restoring its unexpanded shape before the product is loaded, and improving the success rate of product entering the box.
