[0015] The present invention also discloses a method for detecting foreign matter in intelligent butter packaging, which uses the above-mentioned intelligent butter packaging foreign matter detection device, and comprises the following steps:

[0016] S1. When the output end of the third driving motor drives the first one-way threaded screw to rotate, so that the slider drives the packaging bag to move to the position below the feeding pipe for filling, the first driving motor can be started, and the output end of the first driving motor drives the second one-way threaded screw to rotate, thereby driving the movable block to drive the first connecting plate to move downward, so that the first connecting plate drives the end of the discharge nozzle to move to the inside of the packaging bag. When filling, under the control of the PLC controller, the output end of the first driving motor is slowly rotated in the opposite direction, thereby driving the first connecting plate to drive the discharge nozzle to move slowly upward, so that the packaging bag is slowly filled from the bottom upward, thereby reducing the entry of foreign matter in the outside air brought in by direct filling from the top, thereby avoiding interference during the detection process, thereby ensuring the accuracy of the detection;

[0017] S2. When the packaging bag is being filled, the irradiation lamp and the second drive motor are started, the irradiation lamp generates light to irradiate the butter inside the packaging bag, and then the high-speed camera is used to take pictures to detect whether there is foreign matter. The output end of the second drive motor can rotate forward and reverse. The output end of the second drive motor rotates forward to drive the moving block to drive the high-speed camera to move horizontally, thereby expanding the detection range, so as to ensure the accuracy of the detection;

[0018] S3, when the power rod moves downward, it drives the auxiliary plate downward. When the roller contacts the inner inclined groove of the cylinder, the cylinder is pushed to drive the latch to move outside the power rod under the action of the inner inclined groove of the cylinder. When the power rod drives the auxiliary plate to stop moving, the latch moves out from the inside of the auxiliary plate, so that the auxiliary plate is no longer fixed, and then the traction spring drives the second connecting plate to drive the traction rod to move upward, thereby pulling the traction rope through the T-shaped slide bar to drive the spur rack to move horizontally, and then drives the spur gear to drive the sealing plate to move away from the end of the discharge nozzle through the rotating shaft. When the second connecting plate stops moving When the power rod is moved, the sealing plate rotates 180 degrees, so that the discharge port of the discharge nozzle is opened. When the discharge nozzle is reset upward, the second connecting plate is blocked by the L-shaped frame, so that the auxiliary plate can slide relative to the power rod, so that when the power rod moves to the initial position, the latch is aligned with the inner fixing hole of the auxiliary plate, so that the latch can be inserted into the inner side of the auxiliary plate again, so that after the power rod is reset, the sealing plate can cover the discharge port of the discharge nozzle, thereby ensuring that the butter at the discharge port of the discharge nozzle will not adhere to foreign matter in the surrounding environment during the next filling, thereby further improving the accuracy of detection in the subsequent filling process;

[0019] S4. When the auxiliary frame moves downward, the first spherical rod contacts the inclined surface of one side of the arch block, so that the first spherical rod is pushed by the arch block to drive the connecting seat to move horizontally, so that the connecting seat can avoid the U-shaped frame when the auxiliary frame moves downward. After the connecting seat avoids the U-shaped frame, the first spherical rod moves from the highest point of the arch block to the lowest point for reset, thereby ensuring that the high-speed camera is always close to the packaging bag during detection, thereby improving the overall practicality of the device;

[0020] S5. When the first connecting plate moves downward to the inside of the packaging bag, it drives the shielding rubber block to move synchronously. When the first connecting plate moves to the specified position, the second connecting plate moves upward and drives the circular pressure frame to move upward. When the circular pressure frame is separated from the four shielding rubber blocks, the four shielding rubber blocks are reset and expanded to form a cover on the inside of the packaging bag with the first connecting plate, thereby preventing foreign matter from falling into the packaging bag during the filling process, thereby ensuring the stability of the filling.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting a progressive auxiliary mechanism, the output end of the first drive motor drives the second unidirectional threaded screw to rotate, and then drives the movable block to drive the first connecting plate to move downward, so that the first connecting plate drives the end of the discharge nozzle to move to the inside of the packaging bag. During filling, under the control of the PLC controller, the output end of the first drive motor slowly rotates in the opposite direction, thereby driving the first connecting plate to drive the discharge nozzle to move slowly upward, so that the packaging bag is slowly filled from the bottom upward, thereby reducing the entry of foreign matter in the outside air brought by direct filling from the top, thereby avoiding interference during the detection process, thereby ensuring the accuracy of the detection;

[0023] 2. By setting a pushing component, when the auxiliary frame moves downward, the first spherical rod contacts the inclined surface of one side of the arch block, so that the first spherical rod is pushed by the arch block to drive the connecting seat to move horizontally, so that the connecting seat can avoid the U-shaped frame when the auxiliary frame moves downward. After the connecting seat avoids the U-shaped frame, the first spherical rod moves from the highest point of the arch block to the lowest point for reset, thereby ensuring that the high-speed camera is close to the packaging bag during detection, thereby improving the overall practicality of the device;

[0024] 3. By setting a shielding protection member, the sealing plate can be shielded at the discharge port of the discharge nozzle, thereby ensuring that the butter at the discharge port of the discharge nozzle will not adhere to foreign matter in the surrounding environment during the next filling, thereby further improving the accuracy of detection in the subsequent filling process;

[0025] 4. By setting the cooperation of parts such as the circular pressure frame, the first connecting plate moves to the inside of the packaging bag at a certain distance from the bottom of the packaging bag. When the first connecting plate moves downward to the inside of the packaging bag, it drives the shielding rubber block to move synchronously. When the first connecting plate moves to the specified position, the second connecting plate moves upward and drives the circular pressure frame upward. When the circular pressure frame is separated from the four shielding rubber blocks, the four shielding rubber blocks are reset and expanded to form a cover on the inside of the packaging bag with the first connecting plate, thereby preventing foreign matter from falling into the packaging bag during the filling process, thereby ensuring the stability of the filling.

[0050] On the basis of Example 1, the intelligent butter packaging foreign body detection device provided in this embodiment further includes an isolation protection component, which is arranged on the outer wall of the discharge nozzle 39 and is used to isolate the filling. The isolation protection component includes shielding rubber blocks 23 respectively fixedly connected to the four sides of the first connecting plate 9, each shielding rubber block 23 is attached to each other, and a circular pressing frame 24 is fixedly connected to the bottom of the second connecting plate 37, and a slope 38 is arranged on one side of the circular pressing frame 24;

[0051] The first connecting plate 9 moves to a certain distance from the bottom of the packaging bag 3. When the first connecting plate 9 moves downward to the interior of the packaging bag 3, it drives the shielding rubber block 23 to move synchronously. When the first connecting plate 9 moves to the specified position, the second connecting plate 37 moves upward and drives the circular pressing frame 24 to move upward. When the circular pressing frame 24 is separated from the four shielding rubber blocks 23, the four shielding rubber blocks 23 are reset and expanded to form a cover on the interior of the packaging bag 3 with the first connecting plate 9, thereby preventing foreign matter from falling into the interior of the packaging bag 3 during the filling process, thereby ensuring the stability of the filling.

[0052] In combination with the above-mentioned intelligent butter packaging foreign body detection device, an intelligent butter packaging foreign body detection method is provided, which specifically includes the following steps:

[0053] S1. When the output end of the third drive motor 53 drives the first one-way threaded screw 6 to rotate, so that the slider 7 drives the packaging bag 3 to move to the position below the feed pipe 4 for filling, the first drive motor 11 can be started, and the output end of the first drive motor 11 drives the second one-way threaded screw 14 to rotate, thereby driving the movable block 27 to drive the first connecting plate 9 to move downward, so that the first connecting plate 9 drives the end of the discharge nozzle 39 to move to the inside of the packaging bag 3. When filling, under the control of the PLC controller, the output end of the first drive motor 11 is slowly rotated in the opposite direction, thereby driving the first connecting plate 9 to drive the discharge nozzle 39 to move slowly upward, so that the packaging bag 3 is slowly filled from the bottom upward, thereby reducing the entry of foreign matter in the outside air brought by direct filling from the top, thereby avoiding interference during the detection process, thereby ensuring the accuracy of the detection;

[0054] S2. When the packaging bag 3 is being filled, the irradiation lamp 26 and the second drive motor 31 are started. The irradiation lamp 26 generates light to irradiate the butter inside the packaging bag 3. Then, the high-speed camera 33 is used to take pictures to detect whether there are foreign objects. The output end of the second drive motor 31 can rotate forward and reverse. The output end of the second drive motor 31 rotates forward to drive the moving block 32 to drive the high-speed camera 33 to move horizontally, thereby expanding the detection range, so as to ensure the accuracy of the detection.

[0055] S3, the power rod 30 moves downward and drives the auxiliary plate 28 downward. When the roller 17 contacts the inner inclined groove of the cylinder 29, the cylinder 29 is pushed to drive the latch 49 to move to the outside of the power rod 30 under the action of the inner inclined groove of the cylinder 29. When the power rod 30 drives the auxiliary plate 28 to stop moving, the latch 49 moves out from the inside of the auxiliary plate 28, so that the auxiliary plate 28 is no longer fixed, and then the traction spring 54 drives the second connecting plate 37 to drive the traction rod 22 to move upward, thereby pulling the traction rope 42 to drive the spur rack 46 to move horizontally through the T-shaped slide bar 47, and then drives the spur gear 45 to drive the sealing plate 15 to move away from the end of the discharge nozzle 39 through the rotating shaft 44. When the second connecting plate 37 stops moving When the power rod 30 is moved, the sealing plate 15 rotates 180 degrees, so that the discharge port of the discharge nozzle 39 is opened. When the discharge nozzle 39 is reset upward, the second connecting plate 37 is blocked by the L-shaped frame 16, so that the auxiliary plate 28 can slide relative to the power rod 30, so that when the power rod 30 moves to the initial position, the latch 49 is aligned with the inner fixing hole of the auxiliary plate 28, so that the latch 49 can be inserted into the inner side of the auxiliary plate 28 again, so that after the power rod 30 is reset, the sealing plate 15 can cover the discharge port of the discharge nozzle 39, thereby ensuring that the butter at the discharge port of the discharge nozzle 39 will not adhere to foreign matter in the surrounding environment during the next filling, thereby further improving the accuracy of detection in the subsequent filling process;

[0056] S4. When the auxiliary frame 13 moves downward, the first spherical rod 35 contacts the inclined surface of one side of the arch block 18, so that the first spherical rod 35 is pushed by the arch block 18 to drive the connecting seat 19 to move horizontally, so that the connecting seat 19 can avoid the U-shaped frame 10 during the downward movement of the auxiliary frame 13. After the connecting seat 19 avoids the U-shaped frame 10, the first spherical rod 35 moves from the highest point of the arch block 18 to the lowest point for reset, thereby ensuring that the high-speed camera 33 is always close to the packaging bag 3 during detection, thereby improving the overall practicality of the device;

[0057] S5. When the first connecting plate 9 moves downward to the inside of the packaging bag 3, it drives the shielding rubber block 23 to move synchronously. When the first connecting plate 9 moves to the specified position, the second connecting plate 37 moves upward and drives the circular pressing frame 24 to move upward. When the circular pressing frame 24 is separated from the four shielding rubber blocks 23, the four shielding rubber blocks 23 are reset and expanded to form a cover on the inside of the packaging bag 3 with the first connecting plate 9, thereby preventing foreign matter from falling into the packaging bag 3 during the filling process, thereby ensuring the stability of the filling.

[0058] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
