Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0032] Please also refer to Figures 1 to 3 The following describes an automatic waste bag rejection device provided in an embodiment of the present application. The automatic waste bag rejection device includes a platform 101, a lifting column 102, a weighing sensor 103, a machine clamp 104, and a clamping drive mechanism.

[0033] The table 101 is set to a horizontal state; the lifting column 102 is vertically connected to the table 101 and is used to lift and lower relative to the table 101 along its own axis; the weighing sensor 103 is connected to the end of the lifting column 102 and is used for weighing; the machine clamp 104 and the weighing sensor 103 are located on the same side of the table 101 and are spaced apart from the table 101, and the weighing sensor 103 is located directly below the machine clamp 104 in the vertical direction; the clamping drive mechanism is transmission-connected to the machine clamp 104 and is used to drive the machine clamp 104 to open, and the weighing sensor 103 is communicatively connected to the clamping drive mechanism.

[0034] According to the above-mentioned structure provided in this embodiment, in the automatic waste bag rejection device provided in this embodiment, since the table 101 is set in a horizontal state and the lifting column 102 vertically connected to the table 101 can be raised and lowered relative to the table 101 along its own axis, and since the weighing sensor 103 connected to the lifting column 102 is located directly below the machine clamp 104 in the vertical direction, as the lifting column 102 drives the weighing sensor 103 to gradually rise relative to the table 101, the weighing sensor 103 can lift the target package bag clamped in the machine clamp 104 and accurately obtain the weight of the target package bag after the machine clamp 104 loses its force on the target package bag. In this way, the clamping drive mechanism connected to the weighing sensor 103 can automatically control whether the machine clamp 104 opens to release the defective package bag from the machine clamp 104 based on the weight detection signal of the weighing sensor 103, thereby significantly improving the waste bag rejection efficiency, far superior to the existing technology.

[0035] In another embodiment of this application, please refer to Figures 1 to 3 The machine clamp 104 includes a fixed clamp 141 and a dynamic clamp 142 that are arranged in a matching manner, and also includes a sleeve 143 connected to the fixed clamp 141, a push rod 144 connected to the dynamic clamp 142, and a push column 145 connected to the push rod 144. The push rod 144 is movably installed in the interior of the sleeve 143 and can move along the axial direction of the sleeve 143 to drive the dynamic clamp 142 away from the fixed clamp 141. The push column 145 penetrates the side wall of the sleeve 143 along the radial direction of the sleeve 143 and extends from the interior of the sleeve 143 to the outside of the sleeve 143. A long groove 146 for the push column 145 to move is formed on the side wall of the sleeve 143; the clamping drive mechanism includes a column 151 vertically connected to the table 101, a column 151 installed on the column 151, and a push column 145 on the bottom of the sleeve 143. The pushing cylinder 152 and the pushing plate 153 connected to the power end of the pushing cylinder 152, the output direction of the pushing cylinder 152 is parallel to the axial direction of the sleeve 143 and the part of the pushing column 145 extending out of the sleeve 143 is located on the moving path of the pushing plate 153; usually, a hollow retaining ring 148 is provided at one end of the sleeve 143 close to the fixed clamp 141, and the spring 147 is sleeved on the pushing rod 144, and its two ends in the elastic deformation direction are respectively abutted between the retaining ring 148 and the pushing column 145, so that after the external force pushing the dynamic clamp 142 away from the fixed clamp 141 disappears, the pushing rod 144 retreats to automatically move the dynamic clamp 142 closer to the fixed clamp 141, so that the dynamic clamp 142 and the fixed clamp 141 remain in a clamped state.

[0036] According to the above structure provided in this embodiment, when the weighing sensor 103 detects a packaging bag that fails to meet the weight requirements, it can transmit a detection signal to the pushing cylinder 152. Since the portion of the push pin 145 extending out of the sleeve 143 is located on the moving path of the push plate 153, the pushing cylinder 152 can push the push pin 145 to move in the long slot 146 on the sleeve 143 through the push plate 153, and the push rod 144 connected to the push pin 145 can also follow the push pin 145 to move axially along the sleeve 143, and move the dynamic clamp 142 connected to the push rod 144 away from the fixed clamp 141 connected to the sleeve 143. In this way, the release operation of the target packaging bag can be completed quickly, which is conducive to further improving the efficiency of rejecting packaging bags.

[0037] In another embodiment of this application, please refer to Figures 1 to 3 The clamps 104 are arranged in pairs and spaced apart. The push plates 153 have a preset width and are capable of synchronously pushing the two push pins 145 in each pair of clamps 104. According to the structure provided in this embodiment, the paired clamps 104 ensure good clamping stability of the target package bag, while the push plates 153, which can synchronously push the two push pins 145 in each pair of clamps 104, enable each pair of clamps 104 to synchronously release the target package bag, thereby further improving the efficiency of rejecting waste packages.

[0038] In another embodiment of this application, please refer to Figures 1 to 3 The automatic bag rejection device further includes a turntable 106 rotatably mounted on the table 101; the rotation axis of the turntable 106 is perpendicular to the table 101, and multiple groups of machine clamps 104 are connected to the edge of the turntable 106 and are evenly arranged around the rotation axis of the turntable 106. The turntable 106 has a preset radius so that the push pins 145 in each group of machine clamps 104 can be sequentially located in the movement path of the push plate 153 during the rotation of the turntable 106 relative to the table 101. According to the above structure provided in this embodiment, the turntable 106 can sequentially drive the push pins 145 in multiple groups of machine clamps 104 to the movement path of the push plate 153 by rotating around the rotation axis perpendicular to the table 101. In this way, the inspection and rejection process of another group of target packaging bags can be carried out simultaneously while other operation processes are being performed on another group of target packaging bags, which is conducive to further improving the efficiency of packaging bag rejection.

[0039] In another embodiment of this application, please refer to Figures 1 to 3The automatic bag rejection device further includes a flip plate 107 hinged on the load cell 103 and a flip drive mechanism that is transmission-connected to the flip plate 107 and is used to drive the flip plate 107 to rotate relative to the load cell 103. The flip plate 107 is located on the side of the load cell 103 near the clamp 104 and can be controlled by the flip drive mechanism to tilt relative to the table 101 or to be parallel to the table 101. According to the above structure provided in this embodiment, the flip plate 107 can be horizontally placed between the load cell 103 and the target bag during the process of the load cell 103 weighing the target bag. When the target bag fails the weight test and the clamp 104 is opened, the flip plate can be driven by the flip drive mechanism to flip to a tilted position relative to the table 101. In this way, the target bag abutting the flip plate 107 can automatically slide along the inclined surface formed by the flip plate 107 into the defective product collection container, which is conducive to further improving the efficiency of bag rejection.

[0040] In another embodiment of this application, please refer to Figures 1 to 3 The flip drive mechanism further includes a fixed base 181 connected to the lifting column 102, and a flip cylinder 182 mounted on the fixed base 181 and communicatively connected to the load cell 103. At least a portion of the flip plate 107 is located in the extension path of the piston rod in the flip cylinder 182. According to the structure provided in this embodiment, the flip cylinder 182, which is communicatively connected to the load cell 103, can automatically control whether its piston rod extends based on the detection signal from the load cell 103. Since at least a portion of the flip plate 107 is located in the extension path of the piston rod in the flip cylinder 182, the flip cylinder 182 can tilt the flip plate 107 by extending the piston rod, which further improves the efficiency of rejecting packaging bags.

[0041] In another embodiment of this application, please refer to Figures 1 to 3 The flip drive mechanism further includes a support base 183 provided between the flip plate 107 and the weighing sensor 103; the support base 183 is close to the hinge axis between the flip plate 107 and the weighing sensor 103 and can allow the flip plate 107 to be suspended on the side away from the support base 183. According to the above structure provided in this embodiment, since the support base 183 provided between the flip plate 107 and the weighing sensor 103 can allow the flip plate 107 to be suspended on the side away from the support base 183, this, on the one hand, allows the weighing sensor 103 to obtain the weight detection result of the target package more quickly and accurately during the process of the flip plate 107 contacting the target package, and on the other hand, it can also achieve the automatic reset effect of the flip plate 107 under the action of gravity, which is conducive to further improving the efficiency of rejecting waste bags.

[0042] In another embodiment of this application, please refer to Figures 1 to 3 The flip drive mechanism further includes a support plate 184 connected to the support base 183 and stacked with the flip plate 107. According to the structure provided in this embodiment, the support plate 184 stacked with the flip plate 107 can provide stable support for the flip plate 107, which can significantly increase the load capacity of the flip plate 107 and further improve the efficiency of rejecting waste bags.

[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
