[0049] The embodiment of the present application provides a box opening mechanism 100 of a carrier tape winding packaging line, which is used to open the unformed carton 200 on the carrier tape winding packaging line. In an embodiment, as shown in Figures 1-2As shown, in order to facilitate transportation and storage, the unformed carton 200 is in a folded state, which includes adjacent first side 210, second side 220, third side 230 and fourth side 240, when folded, the first side 210 and the second side 220 are coplanar, the third side 230 and the fourth side 240 are coplanar, when opened as a cube, each side is perpendicular to each other, and the first side 210 is opposite to the third side 230, and the second side 220 is opposite to the fourth side 240. The opening mechanism 100 of the carrier tape reel packaging line in this embodiment is to stabilize the fourth side 240, thereby simultaneously driving the third side 230 and the first side 210 to be turned up, and moving to a state perpendicular to the fourth side 240, thereby opening the unformed carton 200.

[0050] As shown, in an embodiment, the opening mechanism 100 of the carrier tape reel packaging line of the present application includes an opening platform 110, a left turning assembly, a right turning assembly, a connecting block 140 and a driving assembly 150. Figures 3-5

[0051] The opening platform 110 is used to place and fix the unformed carton 200. It can be fixed by vacuum adsorption or other means. The left turning assembly includes a left turning plate 121 and a left connecting rod 122, wherein the left turning plate 121 is rotationally connected to the left side of the opening platform 110, and the left connecting rod 122 is arranged below the left turning plate 121, with its first end rotationally connected to the bottom of the left turning plate 121. The right turning assembly includes a right turning plate 131 and a right connecting rod 132, wherein the right turning plate 131 is rotationally connected to the right side of the opening platform 110, and the right connecting rod 132 is arranged below the right turning plate 131, with its first end rotationally connected to the bottom of the right turning plate 131.

[0052] The connecting block 140 is arranged below the opening platform 110, and its left and right ends are rotationally connected to the second ends of the left and right connecting rods 122 and 132, respectively.

[0053] The driving assembly 150 is arranged below the connecting block 140 and connected to the connecting block 140. The driving assembly 150 is used to drive the connecting block 140 to move towards the opening platform 110, so as to drive the left turning plate 121 to be turned up by the left connecting rod 122, and at the same time, drive the right turning plate 131 to be turned up by the right connecting rod 132, thereby opening the unformed carton 200.

[0054] In this embodiment, the left and right connecting rods 132 and the left and right turning plates 131 are symmetrically arranged on both sides of the opening platform 110, so that the turning rhythm of the left and right turning plates 121 and 131 can be kept consistent during the turning up process.

[0055] ​In the box opening mechanism 100 of the carrier tape reel packaging line of the embodiment, the fourth side surface 240 of the unformed carton 200 is locked on the box opening platform 110, the driving assembly 150 drives the connecting block 140 to move towards the box opening platform 110, the connecting block 140 drives the left flap 121 to rotate upwards from a state parallel to the box opening platform 110 to drive the third side surface 230 of the unformed carton 200 to rotate upwards, thereby driving the entire unformed carton 200 to open, at the same time, the connecting block 140 also drives the right flap 131 to rotate upwards from a state parallel to the box opening platform 110, so that the unformed carton 200 is completely opened and supports the first side surface 210 of the unformed carton 200 from the right side in a state perpendicular to the box opening platform 110, at this time, the left flap 121 supports the third side surface 230 of the unformed carton 200 from the left side in a state perpendicular to the box opening platform 110, so that the unformed carton 200 can maintain an open state without deviation. The box opening mechanism 100 of the carrier tape reel packaging line of the embodiment has simple structure, low implementation cost, high synchronization of the left and right flaps, and improved precision and consistency of the packaging process.

[0056] As shown in Figures 3-5 In an embodiment, the driving assembly 150 includes a driving part 151, a driving rod 152, a guide rod 153, and a connecting plate 154. One end of the driving rod 152 is connected with the driving part 151, and the driving part 151 is used to drive the driving rod 152 to move linearly towards the box opening platform 110.

[0057] The other end of the driving rod 152 is connected with the connecting plate 154, the guide rod 153 includes two guide rods arranged parallel to the two sides of the driving rod 152 and connected with the connecting plate 154 respectively, and the connecting plate 154 is connected with the connecting block 140.

[0058] In the embodiment, the driving part 151 drives the driving rod 152 to drive the connecting plate 154 and the connecting block 140 to move linearly towards the box opening platform 110, the two sides of the driving rod 152 are respectively provided with the guide rods 153 used to guide the moving direction of the connecting plate 154, so that the deviation of the connecting plate 154 during forward movement can be limited. In the embodiment, the limiting of the guide rod 153 can be realized by the driving part 151 or by an externally arranged guide assembly, for example, a guide sleeve is arranged on the two sides of the driving part 151 to guide the guide rod 153.

[0059] The driving of the driving part 151 on the driving rod 152 in the embodiment can be realized by a pneumatic element or an electric element.

[0060] In a preferred embodiment, as shown in Figures 3-5As shown, the driving assembly 150 is a guide rod cylinder 160, the driving part 151 is a cylinder body 161 of the guide rod cylinder 160, the driving rod 152 is a piston rod 162 of the guide rod cylinder 160, the guide rod 153 is a guide rod 163 of the guide rod cylinder 160, and the connecting plate 154 is a guide plate 164 of the guide rod cylinder 160. In other embodiments, the driving assembly 150 can also be a common cylinder, and the common cylinder of this embodiment is provided with a guide assembly on the left and right sides thereof for guiding the guide rod 153.

[0061] In order to detect whether the left flap 121 and the right flap 131 are turned to the position, in an embodiment, as shown in Figure 3 The cylinder body 161 of the guide rod cylinder 160 is provided with a first magnetic switch 165 for detecting whether a magnetic ring on the piston inside the guide rod cylinder 160 moves to a first position. In this embodiment, when the piston inside the guide rod cylinder 160 moves to the first position, the left flap 121 and the right flap 131 are completely turned to be perpendicular to the box opening platform 110. If the first magnetic switch 165 does not detect that the magnetic ring on the piston inside the guide rod cylinder 160 moves to the first position after the guide rod cylinder 160 operates, it indicates that the left flap 121 and the right flap 131 fail to be completely turned to be opened, so that the carton cannot be supported from the left and right sides, and the carton cannot be kept in the shaped state after being opened.

[0062] In another embodiment, as shown in Figure 3 The cylinder body 161 of the guide rod cylinder 160 is further provided with a second magnetic switch 166 for detecting whether a magnetic ring on the piston inside the guide rod cylinder 160 moves to a second position, which is on the side away from the guide plate 164 from the first position.

[0063] In this embodiment, the second magnetic switch 166 can be arranged close to the first magnetic switch 165, so as to detect whether the magnetic ring on the piston inside the guide rod cylinder 160 moves to the second position close to the first position when the magnetic ring fails to move to the first position, so as to judge whether the left flap 121 and the right flap 131 are in the position close to the completely turned and opened position. If the second magnetic switch 166 detects the position of the piston of the guide rod cylinder 160 and the first magnetic switch 165 fails to detect the position of the piston, it indicates that the guide rod cylinder 160 encounters certain obstruction or hysteresis, so that the stroke of the piston cannot be completely in place.

[0064] In other embodiments, the second magnetic switch 166 can also be arranged at the position corresponding to the reset of the piston of the guide rod cylinder 160, so as to detect whether the piston is completely reset, and further judge whether the left flap 121 and the right flap 131 are reset, so as to judge whether the unshaped carton 200 can be smoothly placed on the box opening platform 110.

[0065] AsFigures 3-5 As shown, in one embodiment, a first lever arm 1211 is provided at the bottom of the left flap 121, and a second lever arm 1311 is provided at the bottom of the right flap 131; the first end of the left connecting rod 122 is rotatably connected to the first lever arm 1211, and the first end of the right flap 131 is rotatably connected to the second lever arm 1311; the distance between the first end of the left connecting rod 122 and the first end of the right connecting rod 132 is greater than the distance between the second end of the left connecting rod 122 and the second end of the right connecting rod 132.

[0066] In this embodiment, the left and right distance of the connecting block 140 is set to be shorter, so that the lower parts of the left connecting rod 122 and the right connecting rod 132 are both contracted inward, which can reduce the space occupied by the overall opening mechanism 100 of the carrier tape reel packaging line.

[0067] like Figures 3-5 As shown, in one embodiment, the box opening platform 110 includes a base plate 111, a top cover 112, and a vacuum adsorption assembly 113; the top cover 112 is disposed on the base plate 111 and has a plurality of suction holes 1121; the vacuum adsorption assembly 113 is disposed on the base plate 111 and includes a suction nozzle 1131, which is used to drive the suction nozzle 1131 upward into the suction hole 1121 to adsorb the unformed paper box 200.

[0068] Preferred, such as Figures 3-5 As shown, the unpacking mechanism 100 of the carrier tape reel packaging line in this embodiment also includes a fixing plate 170; the driving part 151 and the base plate 111 are respectively fixedly connected to the fixing plate 170, and the fixing plate 170 simultaneously supports the driving part 151 and the unpacking platform 110, avoiding the complex structure caused by setting up separate support mechanisms.

[0069] like Figure 5 As shown, to enhance fixation, in one embodiment, the unpacking mechanism 100 of the carrier reel packaging line of this application further includes a reinforcing plate 180. The reinforcing plate 180 is perpendicular to the back side of the mounting drive unit 151 mounted on the fixing plate 170. The upper end of the reinforcing plate 180 is also fixedly connected to the base plate 111. Through the reinforcing plate 180, the fixed connection between the fixing plate 170 and the unpacking platform 110 can be strengthened, enhancing the stability of the overall structure. Preferably, the width of the reinforcing plate 180 gradually decreases downward from the part connected to the base plate 111, thereby ensuring a stable connection to the base plate 111 while also saving materials.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the application, several modifications and improvements can be made, which all belong to the protection scope of the application. Therefore, the protection scope of the application should be subject to the appended claims, and the description can be used to explain the content of the claims.
