Description

Technical Field

[0002] Quantitative packaging machines are specially designed for accurate measurement of packaging materials. For the packaging of powdered materials, the traditional packaging method is to pack them one by one manually, which requires a large amount of manpower and has low work efficiency. Therefore, a packaging machine is needed to quickly pack the materials into the required packaging materials, which can effectively reduce manpower investment and improve work efficiency. The existing packaging machines achieve quantitative packaging of powdered materials by setting up quantitative devices to ensure that the materials can be accurately packaged in the material packaging container. When performing small-value quantitative packaging, the powdered material flows out slowly in the guide nozzle, causing the powdered material to hang on the wall when moving, resulting in the powdered material not being easy to flow out smoothly during the packaging process. Therefore, the powdered material has poor fluidity in the guide nozzle, resulting in some powdered material remaining on the inner wall of the guide nozzle, resulting in differences in the weight of the powdered material entering the material packaging container, affecting the overall inspection quality of the material packaging container.

[0012] An automatic quantitative packaging machine and a method of using the same, comprising the following steps:

[0013] S1. First, place the material packaging container on the carrier platform, and the material packaging container is located directly below the quantitative feeding nozzle. Then, the packaging body starts to transport the material inside it to the inside of the quantitative feeding nozzle, and the quantitative feeding nozzle transports the material inside it to the inside of the material packaging container;

Then the second push ring moves downward along the quantitative feeding nozzle and drives the arc-shaped ring frame installed outside it to be inserted between the cleaning frame and the quantitative feeding nozzle, and one side of the cleaning frame is fitted with one side of the arc-shaped ring frame, and the limiting ring rotates synchronously under the drive of the collision assembly, so that the limiting ring moves along the outer circumference of the quantitative feeding nozzle, and the cleaning frame rotates along the outside of the arc-shaped ring frame under the rotation of the limiting ring, so as to clean the material outside the arc-shaped ring frame to achieve the best cleaning effect, thereby preventing the metering error caused by residual material in the quantitative feeding nozzle, ensuring that the weight of each package remains accurate, and allowing the load-bearing platform to more accurately capture changes in material weight.

[0017] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0018] By setting the quantitative component, it is possible to maintain hard contact with the material adsorbed inside the quantitative feeding nozzle, so that the residual material in the quantitative feeding nozzle can be cleaned in time, ensuring that the residual material inside the quantitative feeding nozzle can be collected by the material packaging container, avoiding the residue affecting the measurement of subsequent materials and causing inaccurate weight of each package, thereby improving the overall packaging accuracy and improving the overall inspection quality of the packaging container.

[0019] By setting up the material cleaning component, the limit ring, the second push ring and the quantitative feeding nozzle, the material cleaning component can cooperate with the second push ring to clean the material around the second push ring again, reduce the loss during material packaging, and further improve the packaging accuracy of the packaging machine for materials.

[0020] By setting the locking assembly, the cleaning frame, the limiting ring and the second push ring, the cleaning frame can be taken out from the limiting ring and the quantitative feeding nozzle, so that the cleaning frame can achieve a short connection with the second push ring in the quantitative feeding nozzle, which is convenient for taking out and cleaning the second push ring in the quantitative feeding nozzle, and can reduce product contamination caused by impurities or residues, thereby improving the material packaging quality.

[0021] By arranging the swing assembly, the first push ring, the second push ring and the quantitative feeding nozzle, the first push ring and the second push ring can be slowly moved outside and inside the quantitative feeding nozzle, so that the second push ring can achieve the best cleaning effect according to the characteristics of the material, thereby preventing the metering error caused by residual material in the quantitative feeding nozzle, ensuring that the weight of each package remains accurate, and allowing the support table to more accurately capture changes in material weight.

[0022] By setting the collision component, the swing component, the guide cavity and the quantitative feeding nozzle, it is possible to knock on different positions on the outside of the quantitative feeding nozzle, so that the material adsorbed on the inside of the quantitative feeding nozzle can be shaken off.

[0023] By setting up the swing component, power component, collision component, cleaning frame and quantitative feeding nozzle, the second push ring, cleaning frame and collision component can be used to maintain synchronous operation, which can reduce unnecessary energy transfer and thus improve the force transmission efficiency of the equipment. At the same time, the impact plate cooperates with the second push ring so that the material is pushed downward along the quantitative feeding nozzle by the second push ring. Then the material shakes at different positions in the quantitative feeding nozzle, so that the second push ring and the impact plate are synchronized. Without affecting the overall production rhythm, the efficient packaging speed of the packaging device body is improved, thereby reducing the time required for material packaging, improving the overall operating efficiency, and further improving the packaging efficiency of the packaging machine.

[0048] Through the above technical solution:

[0049] When in use;

[0050] In the first step, when the quantitative feeding nozzle 11 is conveying the material inside it into the material packaging container and there is material remaining inside the quantitative feeding nozzle 11, the servo motor 39 drives the second gear 38 to rotate, and then the second gear 38 rotates to mesh with the gear ring frame 37 and drives the first gear 36 to rotate. At this time, the first gear 36 rotates to drive the centering column 35 to rotate along the positioning seat 34, and the centering column 35 rotates to drive the connecting arm 33 to rotate, so that the connecting arm 33 moves in a circle along one side of the positioning seat 34, and the connecting arm 33 rotates along the guide cavity 26 and drives the swing arm 32 to rotate. As a result, the connecting arm 33 rotates and contacts with the swing arm 32, pushing or pulling the positioning shaft column 31 to move upward or downward along the guide cavity 26. As the positioning shaft column 31 moves, it drives the first push ring 24 to move downward along the outside of the quantitative feeding nozzle 11. Subsequently, the first push ring 24 moves and drives the second push ring 25 to move downward along the quantitative feeding nozzle 11. Subsequently, the second push ring 25 and the arc-shaped ring frame 52 contact and push the material adsorbed inside the quantitative feeding nozzle 11, so that the material adsorbed inside the quantitative feeding nozzle 11 is pushed outward along the quantitative feeding nozzle 11, and the pushed out material is collected by the material packaging container.

[0051] In the second step, when the connecting arm 33 and the swing arm 32 rotate along the guide cavity 26 and drive the first push ring 24 to move downward along the outside of the quantitative feeding nozzle 11, the gear ring frame 37 rotates to drive the rotating ring 41 installed inside it to rotate along the displacement groove 42, and then the rotating ring 41 rotates to drive the contact plate 43 to move synchronously. At this time, one side of the contact plate 43 approaches the outside of the convex ring 47 and forms contact with it, and the contact plate 43 contacts with the convex ring 47 under continuous movement and pushes the convex ring 47 to move horizontally along the displacement groove 42, and the movement of the convex ring 47 drives the moving column 45 to move along the through groove 44 and one of the positioning frames 48, so that the movement of the moving column 45 drives the other positioning frame 48 to move synchronously, and then the movement of the moving column 45 drives the impact plate 46 to collide with the outside of the quantitative feeding nozzle 11. When the impact plate 46 collides, it is offset from the connecting arm 33 and the swing arm 32. After the impact plate 46 collides with the outside of the quantitative feeding nozzle 11, the contact plate 43 and the convex ring 47 are offset from each other, and then the spring 49 elastically pushes the other positioning frame 48 to move along the through groove 44. Then the other positioning frame 48 drives the moving column 45 to move along one of the positioning frames 48 and the through groove 44, so that the convex ring 47 moves and resets along the displacement groove 42, and then the impact plate 46 is moved and reset and the impact plate 46 continues to maintain a staggered state with the connecting arm 33 and the swing arm 32 in the guide cavity 26. Therefore, each collision of the impact plate 46 can achieve knocking on different positions on the outside of the quantitative feeding nozzle 11, so that the material adsorbed on the inside of the quantitative feeding nozzle 11 can be shaken off.

[0052] In the third step, when the rotating ring 41 is rotating and the second push ring 25 and the arc-shaped ring frame 52 continue to move downward along the inside of the quantitative feeding nozzle 11, the second push ring 25 and the arc-shaped ring frame 52 move downward and are inserted between the cleaning frame 51 and the quantitative feeding nozzle 11, and then the cleaning frame 51 fits the outside of the arc-shaped ring frame 52. At this time, the rotation of the rotating ring 41 drives the support arm 23 to rotate and drives the limit ring 21 to rotate along the bottom of the quantitative feeding nozzle 11, and the rotation of the limit ring 21 drives the cleaning frame 51 to rotate synchronously, and the cleaning frame 51 rotates to form a conflict with the arc-shaped ring frame 52 and clean the material on the arc-shaped ring frame 52, thereby reducing the loss during material packaging and further improving the packaging accuracy of the packaging machine for materials.

[0053] The fourth step is that when it is necessary to take out the second push ring 25 in the quantitative feeding nozzle 11, the two push plates 64 are triggered to move it relatively along the hollow groove 62, and then the two push plates 64 move to drive the two latch columns 56 to move along the two latch grooves 57 and the latch holes 54 toward the inside of the locking cylinder 61. At this time, the two latch columns 56 are disengaged from the two latch grooves 57 and the two latch holes 54, which is used to prevent the latch plate 55 from losing its connection with the mounting groove 53. As the cleaning frame 51 is pulled, the latch plate 55 is driven to move along the mounting groove 53, so that the latch plate 55 is disengaged from the mounting groove 53 and the cleaning frame 51 is taken out of the quantitative feeding nozzle 11 and the limit ring 21, and then the second push ring 25 is triggered to magnetically separate it from the first push ring 24, and then the second push ring 25 is taken out of the quantitative feeding nozzle 11, which is convenient for taking out and cleaning the second push ring 25 in the quantitative feeding nozzle 11, which can reduce product contamination caused by impurities or residues, thereby improving the material packaging quality.

[0054] An automatic quantitative packaging machine and a method of using the same, comprising the following steps:

[0055] S1. First, place the material packaging container on the carrier 12, and the material packaging container is located directly below the quantitative feeding nozzle 11. Then, the packaging body 1 starts to transport the material inside it to the inside of the quantitative feeding nozzle 11, and the quantitative feeding nozzle 11 transports the material inside it to the inside of the material packaging container;

[0056] S2, after the quantitative feeding nozzle 11 has completed conveying the material inside and there is residual material adsorbed inside the quantitative feeding nozzle 11, the swing assembly 3 is then driven to drive the first push ring 24 to move downward along the outside of the quantitative feeding nozzle 11. At this time, the downward movement of the first push ring 24 drives the second push ring 25 to move downward along the inside of the quantitative feeding nozzle 11 synchronously, so as to push the material adsorbed inside the quantitative feeding nozzle 11 outward from the inside of the quantitative feeding nozzle 11, and the pushed material is collected by the material packaging container;

[0057] S3, the collision component 4 is driven by the swing component 3 to move, and then the collision component 4 is staggered with the swing component 3 and collides with the outside of the quantitative feeding nozzle 11, so as to shake the material adsorbed inside the quantitative feeding nozzle 11, and cooperate with the material pushed downward by the first push ring 24 to shake the material inside the quantitative feeding nozzle 11 into the material packaging container;

[0058] S4. Then, the second push ring 25 moves downward along the quantitative feeding nozzle 11 and drives the arc-shaped ring frame 52 installed outside it to be inserted between the cleaning frame 51 and the quantitative feeding nozzle 11, and one side of the cleaning frame 51 is in contact with one side of the arc-shaped ring frame 52, and the limiting ring 21 rotates synchronously under the drive of the collision component 4, so that the limiting ring 21 moves along the outer circumference of the quantitative feeding nozzle 11, and the cleaning frame 51 rotates along the outside of the arc-shaped ring frame 52 under the rotation of the limiting ring 21, so as to clean the material outside the arc-shaped ring frame 52 to achieve the best cleaning effect, thereby preventing the metering error caused by residual material in the quantitative feeding nozzle 11, ensuring that the weight of each package remains accurate, so that the supporting platform 12 can more accurately capture the change in material weight.
