Description

Technical Field

[0001] This utility model relates to the field of product packaging equipment technology, specifically to an automatic packaging machine. Background Technology

[0002] Packaging machinery plays a crucial role in modern industrial production and daily life. Especially in industries such as food, chemicals, and pharmaceuticals, precise packaging not only affects the appearance quality of products but also directly impacts their performance and shelf life. These industries often encounter situations where two different granular materials need to be mixed and packaged in specific proportions. For example, in the chemical industry, it may be necessary to mix chemical particles with different functions to improve product efficacy.

[0003] Traditional packaging machines typically open one end of a packaging bag, fill the bag with the material, and then seal it. This method is generally sufficient for packaging only one type of material. However, if two mixed materials are used, uneven mixing can lead to an imbalance in the final packaged material ratio. Therefore, we propose an automatic packaging machine to address this issue. Summary of the Invention

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] An automatic packaging machine, comprising:

[0006] A conveyor belt, on one side of which packaging bags are conveyed at equal intervals, the packaging bags having open ends;

[0007] L-shaped plates are symmetrically fixed on both sides of the middle part of the conveyor belt. Support rods are fixed at intervals on the side of the L-shaped plates closest to the conveyor belt, and mounting plates are fixed on the top of the support rods.

[0008] A storage cylinder is symmetrically embedded on both sides of the mounting plate. The lower end of the storage cylinder is conical and connected to a discharge pipe. A solenoid valve is installed on the body of the discharge pipe.

[0009] A bag-opening mechanism, mounted on the support rod, is used to open the bag opening of the packaging bag;

[0010] A feeding mechanism, mounted on the L-shaped plate, is used to convey materials into the packaging bag;

[0011] An ultrasonic sealing machine is installed at the unloading end of the conveyor belt, and is used to seal packaging bags.

[0012] Furthermore, the bag-supporting mechanism includes a movable plate slidably sleeved on the surface of the support rod. A first hydraulic cylinder is installed on the top of the mounting plate, and the piston end of the first hydraulic cylinder is connected to the movable plate. An air pump is installed in the middle of the top of the movable plate. First suction pipes are embedded at the four corners of the movable plate. A second suction pipe is embedded in the side plate of the conveyor belt at the position corresponding to the first suction pipe. The air inlet of the air pump is connected to a diverter pipe through a tee. Both ends of the diverter pipe are connected to air delivery hoses. The first and second suction pipes are both connected to the air delivery hoses.

[0013] Furthermore, the feeding mechanism includes a rectangular frame slidably mounted on the bottom plate of the L-shaped plate. A second hydraulic cylinder is installed on the side plate of the L-shaped plate. The piston end of the second hydraulic cylinder is connected to the outer wall of one side of the rectangular frame. Guide rods are fixed on both sides inside the rectangular frame. A slider is slidably sleeved on the surface of the guide rod. A receiving groove is constructed in the middle of the top of the slider. A spring is connected between the slider and the inner side wall of the rectangular frame. The spring is sleeved on the surface of the guide rod. Extension plates are fixed on both sides of the slider. Strip channels are constructed on both sides of the rectangular frame. The extension plate slides through the strip channels, and an abutment rod is connected to the side of the extension plate located outside the rectangular frame.

[0014] Furthermore, the receiving trough is arc-shaped, and its depth gradually increases from one end near the second hydraulic cylinder to the other end.

[0015] Furthermore, the top surface height of the conveyor belt is greater than the top surface height of the side plate of the conveyor belt, and the length of the packaging bag is greater than the width of the conveyor belt.

[0016] Furthermore, the conveyor belt has symmetrical rectangular notches on the unloading end side, and the ultrasonic sealing machine is installed at the rectangular notches.

[0017] The beneficial effects of this utility model are as follows:

[0018] In use, the two materials are stored in two separate storage cylinders. The release of the materials is controlled by a solenoid valve to achieve a precise ratio. When bagging, the bag-opening mechanism opens both ends of the packaging bag simultaneously, and the feeding mechanism feeds the two materials into the bag. Finally, the ultrasonic sealing machine seals both sides of the packaging bag simultaneously. This allows for efficient and accurate mixing and packaging of two different granular materials, meeting the needs of modern industrial production.

[0019] This utility model, by setting up a conveyor belt, a bag-supporting mechanism, a feeding mechanism, and an ultrasonic sealing machine, allows all parts of the mechanism to work together and operate automatically, improving packaging efficiency, reducing labor costs and errors, and making it highly practical.

The first suction pipe 804 and the second suction pipe 805 are both connected to the gas delivery hose 807.

[0032] A feeding mechanism 9 is mounted on an L-shaped plate 3 and is used to transport materials into a packaging bag 2. The feeding mechanism 9 includes a rectangular frame 901 slidably mounted on the bottom plate of the L-shaped plate 3. A second hydraulic cylinder 902 is mounted on the side plate of the L-shaped plate 3. The piston end of the second hydraulic cylinder 902 is connected to the outer wall of one side of the rectangular frame 901. Guide rods 907 are fixedly mounted on both sides inside the rectangular frame 901. A slider 903 is slidably mounted on the surface of the guide rods 907. A receiving groove 9031 is constructed in the middle of the top of the slider 903. A spring 904 is connected between the slider 903 and the inner side wall of the rectangular frame 901. The spring 904 is mounted on the surface of the guide rods 907. Extension plates 905 are fixedly mounted on both sides of the slider 903.

[0033] An ultrasonic sealing machine 10 is installed at the unloading end of the conveyor belt 1. The ultrasonic sealing machine 10 is used to seal the packaging bag 2.

[0034] Working principle and process description:

[0035] (1) Initialization phase:

[0036] Conveyor belt 1 starts running, conveying packaging bags 2 to the work area at equal intervals;

[0037] The storage cylinder 6 is filled with two different granular materials.

[0038] (2) Bag-filling stage:

[0039] After the packaging bag 2 on the conveyor belt 1 reaches the designated position, the air pump 803 of the bag-supporting mechanism 8 is started.

[0040] The air pump 803 generates negative pressure through the air delivery hose 807, the diversion pipe 806 and the suction pipe, which adsorbs and opens the upper and lower ports of the packaging bag 2.

[0041] (3) Loading stage:

[0042] The solenoid valve of the storage cylinder 6 opens according to the set ratio and time, and the material falls into the receiving trough 9031 through the discharge pipe 7 (at this time, one side of the slider 903 is in contact with the rectangular frame 901, and the material cannot fall from the rectangular frame 901).

[0043] The second hydraulic cylinder 902 of the feeding mechanism 9 pushes the rectangular frame 901 to move towards the packaging bag 2. When the two rectangular frames 901 approach each other (extend into the opening of the packaging bag 2), the abutting rods 906 abut against each other, causing the spring 904 to compress. The slider 903 moves closer to the side of the spring 904. At this time, the material can slide down from the receiving groove 9031, pass through the rectangular frame 901, and fall into the middle of the packaging bag 2. Then, the second hydraulic cylinder 902 of the feeding mechanism 9 pulls the rectangular frame 901 away from the packaging bag 2. In this way, the two different materials are loaded in the middle of the packaging bag 2 in a certain proportion.

[0044] (4) Sealing stage:

[0045] The packaging bag 2 filled with materials is moved to the unloading end of the conveyor belt 1;

[0046] The ultrasonic sealing machine 10 seals both ends of the packaging bag 2 to ensure a tight seal.

[0047] (5) Completion stage:

[0048] The sealed packaging bag 2 is conveyed by conveyor belt 1 to the collection area or subsequent processing area;

[0049] The equipment is ready for the next packaging cycle.

[0050] This automatic packaging machine, through the combined design of conveyor belt 1, bag-supporting mechanism 8, feeding mechanism 9 and ultrasonic sealing machine 10, can efficiently and accurately complete the mixed packaging of two different granular materials, meeting the needs of modern industrial production.

[0051] like Figure 3 As shown, in some embodiments, the receiving groove 9031 is arc-shaped, and its depth gradually increases from one end near the second hydraulic cylinder 902 to the other end. More specifically, since the receiving groove 9031 is arc-shaped and shallow on one side and deep on the other side, it helps to utilize the gravity of the material to make it slide down naturally, pass through the rectangular frame 901, and smoothly enter the packaging bag 2.

[0052] like Figure 1As shown, in some embodiments, the top surface height of the conveyor belt 1 is greater than the top surface height of the side plate of the conveyor belt 1, and the length of the packaging bag 2 is greater than the width of the conveyor belt 1. More specifically, the top surface height of the conveyor belt 1 is greater than the top surface height of the side plate of the conveyor belt 1. In this way, the main body of the packaging bag 2 is supported by the conveyor belt, which can reduce the friction between the packaging bag 2 and the side plate and make its movement smoother. In addition, the bag supporting mechanism 8 is set on the side plate of the conveyor belt 1, and the length of the packaging bag 2 is greater than the width of the conveyor belt 1, so that the bag supporting mechanism 8 can work normally.

[0053] like Figure 1 As shown, in some embodiments, the unloading end of the conveyor belt 1 is symmetrically constructed with rectangular notches, and the ultrasonic sealing machine 10 is installed at the rectangular notches. More specifically, by setting the rectangular notches, the ultrasonic sealing machine 10 can seal the bag closer to the center of the packaging bag 2, thereby improving the packaging effect. It should be noted that the ultrasonic sealing machine 10 is existing technology, and its working principle and circuit connection will not be described in detail.

[0054] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
