[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] Depend on Figure 1 , Figure 2 and Figure 3As shown, a quantitative weighing component of a packaging machine includes a fixed side plate 1 and a workbench 2. The workbench 2 is symmetrically fixedly installed on the side of the fixed side plate 1. A material bag 3 is arranged on the top of the workbench 2. An adsorption mechanism 4 is fixedly installed on the upper surface of the workbench 2. The adsorption mechanism 4 includes a conductive cylinder 41, a connecting end 42, and a suction cup 43. The top of the workbench 2 is located on the side of the material bag 3 and is provided with a conductive cylinder 41. The connecting end 42 is fixedly installed at the end of the conductive cylinder 41, and the suction cup 43 is fixedly installed at the other end of the conductive cylinder 41. The top of the suction cup 43 is fixedly connected to the conductive cylinder 41. The side of the material bag 3 is fitted and adsorbed. During use, the material bag 3 is placed on the top of the workbench 2, and the connecting end 42 is connected to the pump body pipeline. Then, the air pressure inside the conductive tube 41 is reduced through the operation of the pump body, and a negative pressure space is formed inside the conductive tube 41. At this time, the suction cup 43 is fitted to the side of the material bag 3. The suction cup 43 can stably adsorb the side surface of the material bag 3. In conjunction with the use of other components, the opening of the material bag 3 can be stably opened, which is convenient for the stable input of materials into the interior.

[0030] By the attached Figure 2 As shown, in this embodiment, the adsorption mechanism 4 also includes a matching ring 44, a pushing component 45 and a positioning component 46. The matching ring 44 is fixedly installed on the outside of the conductive tube 41, the pushing component 45 is fixedly installed on the side of the bottom end of the matching ring 44, and the positioning component 46 is fixedly installed on the bottom end of the pushing component 45. The bottom end of the positioning component 46 is fixedly connected to the surface of the workbench 2. During use, the adsorption mechanism 4 can be installed as a whole to the upper end of the workbench 2 through the use of the positioning component 46. Driven by the operation of the pushing component 45, the matching ring 44 moves synchronously with the output end of the pushing component 45. During the movement, the conductive tube 41 and the parts on the side of the conductive tube 41 can be driven to move synchronously, and the distance between the suction cup 43 and the material bag 3 can be flexibly controlled, which is convenient for the subsequent control of the opening size of the material bag 3.

[0031] By the attached Figure 3 As shown, in this embodiment, the pushing assembly 45 includes a cylinder 451, a sliding rod 452 and a moving block 453. The cylinder 451 is fixedly installed on the side of the positioning assembly 46, the sliding rod 452 is fixedly installed at the output end of the cylinder 451, and the moving block 453 is fixedly installed at the end of the sliding rod 452. The moving block 453 is fixedly connected to the bottom end of the matching ring 44. During use, through the operation of the cylinder 451, the sliding rod 452 follows the output end of the cylinder 451 to perform telescopic movement synchronously, and the moving block 453 moves synchronously under the drive of the sliding rod 452, and provides power for the operation of the matching ring 44 and the upper end components during the movement of the moving block 453.

[0032] By the attached Figure 3As shown, in this embodiment, the positioning assembly 46 includes a base plate 461, a receiving arm 462, a reinforcement rod 463, a fixing rod 464 and a fixing groove 465. The base plate 461 is fixedly mounted at the end of the cylinder 451, and the receiving arm 462 is symmetrically arranged on the side of the base plate 461. The receiving arm 462 and the base plate 461 are threadedly mounted with the reinforcement rod 463, and the fixing rod 464 is threadedly mounted on the side of the end of the receiving arm 462 away from the reinforcement rod 463. The upper surface of the workbench 2 is symmetrically provided with fixing grooves 465, and the fixing grooves 465 are symmetrically arranged with the fixing grooves 465. The fixing rod 464 is threadedly connected. During use, the reinforcing rod 463 is used to stably connect and fit the receiving arm 462 to the base plate 461. Then, the receiving arm 462 is moved according to the position of the pushing component 45, the conductive cylinder 41, the suction cup 43 itself and the distance from the side surface of the material bag 3. The receiving arm 462 is moved to the target position at the upper end of the workbench 2, and the fixing rod 464 is passed through the receiving arm 462 and transferred into the fixing groove 465 to complete the fixation of the receiving arm 462 itself, which is convenient for locking the position of the overall components of the adsorption mechanism 4.

[0033] By the attached Figure 4 As shown, in this embodiment, the clamping mechanism 5 includes a clamping block 51, which is symmetrically arranged on the top of the workbench 2. The inner wall of the clamping block 51 is squeezed and fitted with the two sides of the material bag 3. During use, through the operation and cooperation of the various components of the clamping mechanism 5, the positions of multiple groups of clamping blocks 51 can be adjusted, and the distance between the clamping blocks 51 can be reduced, so that the clamping blocks 51 can clamp the two sides of the material bag 3 to ensure the stability of the material bag 3 when the material is infused.

[0034] By the attached Figure 5 As shown, in the present embodiment, the clamping mechanism 5 further comprises a swing arm 52, a steering rod 53, a pushing rod 54 and a rotating rod 55. The swing arm 52 is symmetrically fixedly mounted at the end of the clamping block 51, and the steering rod 53 is symmetrically fixedly mounted inside the workbench 2. The steering rod 53 is rotatably connected to the swing arm 52, the pushing rod 54 is rotatably mounted at the end of the steering rod 53, and the rotating rod 55 is rotatably mounted at the bottom end of the pushing rod 54. During use, the position height of the rotating rod 55 itself changes through the operation of the internal components of the clamping mechanism 5, and the rotating rod 55 moves toward the lower end. During the movement, the distance between the rotating rod 55 and the end of the swing arm 52 gradually decreases. The existence of the pushing rod 54 allows the end of the swing arm 52 to be squeezed and automatically rotate to the side away from the rotating rod 55. Through the conduction of the swing arm 52 and the use of the steering rod 53, the clamping block 51 moves toward the middle end instead, and clamps the outer side of the material bag 3 at the middle end.

[0035] By the attached Figure 5As shown, in this embodiment, the clamping mechanism 5 also includes a lifting block 56, a lifting component 57 and a weighing sensor 58. The lifting component 57 is fixedly installed inside the workbench 2. The lifting block 56 is fixedly installed at the output end of the lifting component 57. The lifting block 56 is rotatably connected to the rotating rod 55. A weighing sensor 58 is fixedly installed on one side of the workbench 2. During use, through the operation of the lifting component 57, the lifting block 56 as a whole will move downward under the drive of the lifting component 57, so as to control the overall position height of the rotating rod 55, which is convenient for changing and adjusting the angle and position of the clamping block 51. In addition, as the amount of material inside the material bag 3 gradually increases, the pressure on the lifting block 56 itself gradually increases. At this time, with the cooperation of the lifting component 57, the weighing sensor 58 can detect the size of such pressure in real time, which is convenient for real-time detection of the total weight of the material inside the material bag 3.

[0036] By the attached Figure 6 As shown, in this embodiment, the lifting assembly 57 also includes a lifting cylinder 571, a connecting port 572 and a pulling rod 573. The lifting cylinder 571 is fixedly installed inside the workbench 2, the connecting port 572 is symmetrically fixedly installed on the side of the lifting cylinder 571, the pulling rod 573 is fixedly installed at the output end of the lifting cylinder 571, and the top of the pulling rod 573 is fixedly connected to the lifting block 56. During use, the connection port 572 is used to provide power for the operation of the lifting cylinder 571 itself, and then the pulling rod 573 moves up and down at the top of the lifting cylinder 571 according to the pressure of the gas input inside the connecting port 572, so as to facilitate real-time changes in the position of the lifting block 56.

[0037] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions.
