[0002] Multi-station carton unfolding equipment, also known as multi-station carton opener, is an important equipment on the carton automated packaging production line. It can automatically complete the processes of carton unfolding, forming, bottom sealing, etc. according to the preset program without manual operation one by one, which greatly improves the packaging efficiency.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0041] like Figure 1-10 As shown, the present application provides a multi-station carton unfolding device, comprising: a processing frame 1, a placement structure 101 installed on one side of the processing frame 1, a suction structure 102 installed inside the processing frame 1, a closing structure 103, a handling structure 104 and a conveying structure 105;

[0042] The unfolding mechanism 2 is arranged inside the processing frame 1, and the unfolding mechanism 2 includes a rotating shaft 203 located above the processing frame 1, an unfolding plate 1 204 fixedly installed on the outer wall of the rotating shaft 203, and an unfolding plate 211 arranged on one side of the unfolding plate 1 204, which is used to squeeze and unfold the carton;

[0043] Specifically, Figure 1-8 As shown, a rotating cylinder 201 is fixedly installed on the top surface of the processing frame 1, and a rotating plate 202 is fixedly installed on the output end of the rotating cylinder 201. The rotating plate 202 is of a special shape, and the top surface of the rotating plate 202 is fixedly connected to the bottom surface of the rotating shaft 203.

[0044] In this embodiment: the rotating plate 202 is driven to rotate by the rotating cylinder 201, and the rotating plate 202 drives the rotating shaft 203 and the unfolding plate 1 204 to rotate, and the unfolding plate 1 204 and the unfolding plate 2 211 are used to squeeze the two sides of the carton to ensure that the carton is quickly unfolded with high efficiency.

[0045] Specifically, Figure 1-8 As shown, a fixing block 1 205 and a fixing block 207 are fixedly installed on the top surface of the processing frame 1, and the fixing block 1 205 and the fixing block 2 207 are in a vertical position. A stop column 1 206 and a stop column 208 are fixedly installed through the side surface of the fixing block 1 205 and the side surface of the fixing block 2 207 respectively.

[0046] In this embodiment: when the rotating plate 202 rotates, the rotating plate 202 contacts the stop post 1 206 and the stop post 208. Since the stop post 1 206 is perpendicular to the stop post 208, and the stop post 1 206 and the stop post 208 jointly limit the rotating plate 202 to rotate 90 degrees, and ensure that the rotating plate 202 drives the upper unfolding plate 1 204 not to rotate too large an angle to cause the carton to bend, thereby improving the quality of the unfolding of the carton.

[0047] Specifically, Figure 1-8 As shown, a support frame 209 is fixedly installed on the top surface of the processing frame 1, a linear cylinder 210 is fixedly installed on the side of the support frame 209, a connecting plate 212 is fixedly installed on the output end of the linear cylinder 210, and the side of the connecting plate 212 is fixedly connected to the side of the second unfolding plate 211.

[0048] In this embodiment: the linear cylinder 210 drives the connecting plate 212 to move, the connecting plate 212 drives the second unfolding plate 211 to move, and the second unfolding plate 211 and the first unfolding plate 204 are used together to squeeze and unfold the carton.

[0049] The anti-folding mechanism 3 is arranged on one side of the unfolding plate 211. The anti-folding mechanism 3 includes an anti-folding plate 1 301 fixedly installed on the side of the unfolding plate 211. A rotating rod 310 is arranged on one side of the anti-folding plate 1 301. An anti-folding plate 2 315 is fixedly installed on the outer wall of one end of the rotating rod 310 through a fixing sleeve 316, so as to prevent the side of the carton from bending during the unfolding process;

[0050] Specifically, Figure 1-10 As shown, a T-shaped slot 303 is provided on the side of the anti-folding plate 301, a T-shaped block 302 is slidably connected to the inner wall of the T-shaped slot 303, an elastic member 304 is fixedly installed on the side of the T-shaped block 302, the other end of the elastic member 304 is fixedly connected to the inner wall of one end of the T-shaped slot 303, and a supporting hole 305 is provided on the side of the T-shaped block 302.

[0051] In this embodiment: by setting the anti-folding plate 301, the other side of the carton can be partially limited to prevent over-folding, and by setting the T-slot 303, the T-block 302 is limited, and the elastic member 304 can push the T-block 302 to move smoothly in a straight line without being easily offset, thereby improving the subsequent transmission quality.

[0052] Specifically, Figure 1-10 As shown, a support plate 306 is fixedly installed on the side of the support frame 209, a mounting plate 307 is fixedly installed on the side of the support plate 306, a support rod 308 is fixedly installed on the side of the mounting plate 307, and the outer wall of one end of the support rod 308 is slidably connected to the inner wall of the support hole 305.

[0053] In this embodiment: through the setting of the support rod 308, when the anti-folding plate 301 drives the T-shaped block 302 to move, the support rod 308 can cooperate with the support hole 305 on the T-shaped block 302 to stably support the T-shaped block 302, ensuring that when the T-shaped block 302 moves toward the support rod 308, the T-shaped block 302 can move relatively inside the T-shaped groove 303.

[0054] Specifically, Figure 1-10 As shown, two hinged rods 309 are hinged on the side of T-shaped block 1 302, there are two rotating rods 310, the other ends of the two hinged rods 309 are hinged to one end of the two rotating rods 310 respectively, the outer walls of the two rotating rods 310 are hinged to the side of anti-folding plate 1 301, and there are two anti-folding plates 2 315.

[0055] In this embodiment: the two hinged rods 309 are driven to move by the T-shaped block 1 302, and the two hinged rods 309 respectively drive one end of the two rotating rods 310 to rotate. When the other ends of the two rotating rods 310 rotate, they respectively drive the two anti-folding plates 315 to rotate a certain angle. The two anti-folding plates 315 cooperate with the anti-folding plate 1 301 to limit the side of the carton, ensuring that the carton is not easily over-folded and creases appear, thereby improving the quality of the carton. When the anti-folding plates 315 are driven by the rotating rod 310 to rotate to the original position, the anti-folding plates 315 can be prevented from blocking the feeding of the carton, thereby ensuring the smooth processing of the carton and improving the efficiency.

[0056] Specifically, Figure 1-10 As shown, a fixed rod 311 is fixedly installed on the outer wall of one end of the two rotating rods 310, and a rotating block 312 is fixedly installed on one end of the two fixed rods 311. Two arc grooves 313 are opened on the side of the anti-folding plate 301, and the inner walls of the two arc grooves 313 are respectively slidably connected to the outer walls of the two rotating blocks 312. The inner walls of the two arc grooves 313 are respectively fixedly installed with an arc rod 314, and the inner walls of the two rotating blocks 312 are respectively slidably connected to the outer walls of the two arc rods 314.

[0057] In this embodiment: when the rotating rod 310 rotates, the fixed rod 311 and the rotating block 312 are driven to rotate, and the rotating block 312 rotates on the inner wall of the arc groove 313. Through the setting of the arc rod 314, the rotating block 312 can be further limited to ensure that the rotating block 312 rotates more smoothly, thereby ensuring that the rotating rod 310 rotates more smoothly and improving stability.

[0058] The smoothing mechanism 4 is arranged on both sides of the second unfolding plate 211. The smoothing mechanism 4 includes smoothing plates 406 arranged on the upper and lower sides of the second unfolding plate 211, and is used to smooth the folds of the carton.

[0059] Specifically, Figure 1-10 As shown, the outer walls of the two rotating rods 310 are respectively provided with adjustment grooves 402, the inner walls of the two adjustment grooves 402 are respectively hinged with adjustment rods 401, the other ends of the two adjustment rods 401 are respectively hinged with T-shaped blocks 403, and the side of the anti-folding plate 301 is provided with two T-shaped grooves 404, and the outer walls of the two T-shaped blocks 403 are respectively slidably connected with the inner walls of the two T-shaped grooves 404.

[0060] In this embodiment, the rotating rod 310 rotates to drive the adjusting rod 401 to move, and the adjusting rod 401 drives the second T-shaped block 403 to move. The second T-shaped groove 404 limits the second T-shaped block 403 to ensure that the second T-shaped block 403 can move smoothly in a straight line.

[0061] Specifically, Figure 1-10As shown, two T-shaped blocks 403 are respectively fixedly installed with L-shaped rods 405 away from the side, and the other ends of the two L-shaped rods 405 are respectively fixedly connected to the sides of two smoothing plates 406.

[0062] In this embodiment: when the T-shaped block 403 moves, it drives the L-shaped rod 405 to move, and the L-shaped rod 405 drives the smoothing plate 406 to move, so that the folds of the carton can be pressurized and smoothed, and the carton can be further squeezed and unfolded to ensure that the carton unfolds more smoothly.

[0063] The specific solution is as follows: a carton is placed on the placement structure 101, and the carton is sucked to the unfolding position by the suction structure 102. The rotating cylinder 201 drives the rotating plate 202 and the rotating shaft 203 to rotate, and the rotating shaft 203 drives the unfolding plate 1 204 to rotate. At the same time, the linear cylinder 210 drives the connecting plate 212 and the unfolding plate 211 to move. Under the joint action of the unfolding plate 1 204 and the unfolding plate 211, the carton is squeezed and unfolded, and there is no need to manually unfold the carton, which reduces the labor of workers. When the unfolding plate 211 moves, it drives the anti-folding plate 1 301 to move, and the anti-folding plate 1 301 with The movable T-shaped block 1 302 moves away from the support rod 308. Under the action of the elastic member 304, the T-shaped block 1 302 is pushed to slide relatively in the T-shaped groove 1 303. The T-shaped block 1 302 drives the two hinged rods 309 to move. The two hinged rods 309 drive one end of the two rotating rods 310 to rotate. The other ends of the two rotating rods 310 respectively drive the fixed sleeve 316 and the two anti-folding plates 2 315 to rotate 90 degrees. Under the joint action of the two anti-folding plates 2 315 and the anti-folding plate 1 301, one side of the carton is limited and blocked, and the two sides of the carton are evenly stressed and not easy to bend outward excessively Folding, ugly creases are not easy to appear on the side of the carton, ensuring the overall structural strength and aesthetics of the carton, thereby improving the quality of the carton, the two rotating rods 310 rotate at the same time, driving the two adjusting rods 401 to move, the two adjusting rods 401 respectively drive the two T-shaped blocks 403 to move, the two T-shaped blocks 403 respectively drive the two L-shaped rods 405 to move away from each other, the two L-shaped rods 405 respectively drive the two smoothing plates 406 to move away from each other, the two smoothing plates 406 move and squeeze and smooth the creases of the carton at the same time, and further unfold the carton to ensure that the side of the carton is unfolded The opening is more stable, and the quality of the unfolding is improved. Then, the unfolding plate 1 204 and the unfolding plate 2 211 are restored to their original positions, and the support hole 305 on the T-shaped block 1 302 contacts the support rod 308, so that the T-shaped block 1 302 moves in the T-shaped slot 1 303 to squeeze the elastic member 304. The T-shaped block 1 302 drives the rotating rod 310 and the anti-folding plate 2 315 to rotate to a vertical state through the structure, and will not block the entry of the next carton. The bottom of the carton is closed by the closing structure 103, and the carton is moved to the conveying structure 105 by the carrying structure 104, and then transported to the required position.
