[0023] During operation, when it is necessary to conduct random inspections on the goods, the second screw 34 is first driven by the second motor 22 to move the second moving block 35 and the first weighing platform 39 connected thereto to the bottom of the tool 32. Due to the presence of the slide bar 33 and the fifth moving block 38, the first weighing platform 39 can remain stable. A first weighing piece 40 is installed on the upper surface of the first weighing platform 39 for measuring the weight of the goods, thereby improving work efficiency.
[0024] Furthermore, a first weighing piece 40 is installed on the upper surface of the first weighing platform 39, a connecting plate 42 is fixed between the two side surfaces of the second moving block 35 and the fifth moving block 38, and a second vacuum generator 45 is installed on the bottom surface of the connecting plate 42. Three groups of second suction cups 41 are provided on the first weighing platform 39, and the output end of the second vacuum generator 45 is connected to a second air pipe 46, and the other end of the second air pipe 46 is connected to the three groups of suction cups. A fourth support frame 36 is installed on the outer surface of the second moving block 35, and a fourth motor 37 is installed on the fourth support frame 36. The output end of the fourth motor 37 is connected to a rotating shaft 43, and the rotating shaft 43 is installed between the second moving block 35 and the fifth moving block 38. A cam 44 is installed on the rotating shaft 43, and the cam 44 is located below the first weighing platform 39. When the cam 44 rotates to the highest point, the first weighing platform 39 is in a horizontal state.
[0025] During operation, when it is necessary to fix the goods, the second vacuum generator 45 is started. The second vacuum generator 45 provides negative pressure to the three groups of suction cups through the second air pipe 46, so that the suction cups are tightly adsorbed on the surface of the goods. Before weighing, the fourth motor 37 drives the rotating shaft 43 to rotate, so that the cam 44 rotates to its highest point. At this time, due to the shape and position design of the cam 44, the first weighing platform 39 will be in a horizontal state to ensure the accuracy of weighing. When the product packaging bag is broken, the fourth motor 37 is started. The fourth motor 37 drives the rotating shaft 43 to rotate, and the rotation of the rotating shaft 43 drives the cam 44 to rotate. When the cam 44 rotates, the first weighing platform 39 is in a semi-inclined state, thereby pouring the goods out of the packaging bag, thereby improving work efficiency.
[0026] Furthermore, a console 10 is installed above the second support plate 11, a first trough body 12 is installed on the side of the second support plate 11, a first slide groove 48 is opened on the inner wall of the first trough body 12, a first support frame 18 is installed on the outer end surface of the first trough body 12, a first motor 19 is installed on the first support frame 18, the output end of the first motor 19 is connected to the first screw 51, a first moving block 50 is installed on the first screw 51, first sliders 49 are installed on both sides of the first moving block 50, the first sliders 49 are slidably set in the first slide groove 48, the bottom surface of the first moving block 50 is connected to the first cylinder 15, the output end of the first cylinder 15 is connected to the first telescopic rod 16, the bottom surface of the first telescopic rod 16 is installed with a first suction cup 17, the top surface of the first trough body 12 is installed with a first vacuum generator 13, the output end of the first vacuum generator 13 is connected to the first air pipe 14, and the other end of the first air pipe 14 is connected to the first suction cup 17.
[0027] During operation, when it is necessary to conduct random inspection of the goods, the first motor 19 is started through the console 10, and the motor drives the first screw 51 to rotate. The rotation of the screw causes the first moving block 50 to move along the screw. At the same time, the first slider 49 slides in the first slide groove 48 to ensure the stability of the moving block. After the moving block moves to the specified position, the motor stops working and the first cylinder 15 is started through the console 10. The cylinder drives the first telescopic rod 16 to extend downward. The extension of the telescopic rod causes the first suction cup 17 to approach and contact the goods. At the same time, the first vacuum generator 13 is started to generate negative pressure and transmit it to the suction cup through the first air pipe 14. The suction cup tightly adsorbs the goods under the action of negative pressure. After the goods are adsorbed, the goods are placed on the first weighing platform 39 under the control of the console 10, which improves work efficiency.
[0028] Furthermore, a second cylinder 23 is installed under the first trough body 12, and the output end of the second cylinder 23 is connected to the second telescopic rod 24, and the bottom end of the second telescopic rod 24 is installed with a second trough body 25, and a second slide groove 28 is provided on the inner wall of the second trough body 25. A third support frame 26 is installed on the outer side of the second trough body 25, and a third motor 27 is installed on the third support frame 26. The output end of the third motor 27 is connected to a third screw 30, and the third screw 30 is installed in the second trough body 25. A third moving block 31 is installed on the third screw 30, and second sliders 29 are connected on both sides of the third moving block 31. The second slider 29 is slidably set in the second slide groove 28, and a tool 32 is installed on the bottom surface of the third moving block 31, and the tool 32 is located above the first weighing platform 39.
[0029] During operation, when it is necessary to cut the product packaging bag, the second cylinder 23 is started through the console 10, and the second cylinder 23 drives the second telescopic rod 24 to extend downward, driving the second trough 25 and its internal components to drop vertically. After the second trough 25 drops to a suitable position, the second cylinder 23 stops working to keep the position stable. When the tool 32 moves to the top of the product and is aligned, the third motor 27 is started, and the third motor 27 drives the third screw 30 to rotate. The rotation of the third screw 30 causes the third moving block 31 to move horizontally along the third screw 30. At the same time, the second slider 29 slides in the second slide groove 28 to ensure the stability of the third moving block 31, thereby realizing the cutting of the product packaging bag by the tool 32, thereby improving work efficiency.
[0030] Furthermore, a second weighing platform 4 is installed on the workbench 1, a second weighing piece 5 is installed in the second weighing platform 4, the second weighing platform 4 is located below the rectangular frame 20, a fixed block 7 is fixed to the outside of the first support plate 6, a mounting frame 8 is installed on the fixed block 7, and a counter 9 is installed on the mounting frame 8.
[0031] During operation, after the product packaging bag is cut by the knife 32, the first weighing platform 39 is transferred to the top of the second weighing platform 4 through the fifth moving block 38 and the second moving block 35. The first weighing platform 39 is rotated by rotating the cam 44, so that the product in the packaging bag is poured into the second weighing platform 4, and the net content of the product is weighed by the second weighing piece 5. A counter 9 is installed on the first support plate 6 for recording the number of products sampled, thereby improving work efficiency.
[0032] Furthermore, four groups of support columns 2 are provided below the workbench 1 , and bosses 3 are installed below the four groups of support columns 2 .
[0033] When working, it is supported on the ground by four groups of support columns 2. Bosses 3 are installed under the support columns 2 to increase stability.
[0034] Working principle: When it is necessary to conduct random inspection on the goods, the first motor 19 is started through the control console 10, and the motor drives the first screw 51 to rotate. The rotation of the screw causes the first moving block 50 to move along the screw. At the same time, the first slider 49 slides in the first slide groove 48 to ensure the stability of the moving block. After the moving block moves to the specified position, the motor stops working and the first cylinder 15 is started through the control console 10. The cylinder drives the first telescopic rod 16 to extend downward. The extension of the telescopic rod makes the first suction cup 17 approach and contact the goods. At the same time, the first vacuum generator 13 is started. The first vacuum generator 13 adopts the ZL6MF04 model to generate negative pressure and pass through the first air pipe 14 The suction cups tightly adsorb the goods under the action of negative pressure. After the goods are adsorbed, the control console 10 controls the goods to be placed on the first weighing platform 39. When the goods need to be fixed, the second vacuum generator 45 is started. The second vacuum generator 45 adopts the ZL3H04-B model. The second vacuum generator 45 provides negative pressure to the three groups of suction cups through the second air pipe 46, so that the suction cups are tightly adsorbed on the surface of the goods. Before weighing, the fourth motor 37 drives the rotating shaft 43 to rotate, so that the cam 44 rotates to its highest point. At this time, due to the shape and position design of the cam 44, the first weighing platform 39 will be in a horizontal state, ensuring the accuracy of weighing;
[0035] When it is necessary to cut the product packaging bag, the second cylinder 23 is started through the console 10, and the second cylinder 23 drives the second telescopic rod 24 to extend downward, driving the second trough 25 and its internal components to descend vertically. After the second trough 25 descends to a suitable position, the second cylinder 23 stops working to keep the position stable. When the cutter 32 moves to the top of the product and is aligned, the third motor 27 is started, and the third motor 27 drives the third screw 30 to rotate. The rotation of the third screw 30 causes the third moving block 31 to move horizontally along the third screw 30, and at the same time the second slider 29 slides in the second slide groove 28. , ensuring the stability of the third moving block 31, so that the tool 32 can cut the product packaging bag. After the cutting is completed, the second screw 34 is driven by the second motor 22 to move the second moving block 35 and the first weighing platform 39 connected thereto to the top of the second weighing platform 4, and the fourth motor 37 is started. The fourth motor 37 drives the rotating shaft 43 to rotate, and the rotation of the rotating shaft 43 drives the cam 44 to rotate. When the cam 44 rotates, the first weighing platform 39 is in a semi-inclined state, thereby pouring the product out of the packaging bag, and completing the weighing of the net content of the product through the second weighing piece 5, thereby improving work efficiency.
