Description

Technical Field

[0001] The invention relates to automatic filling equipment for products such as glass glue, and in particular to automatic filling equipment for packaging tubes. Background Art

[0002] In 2021, our company developed a set of automatic filling equipment. The technical solution is shown in the Chinese utility model patent with patent number "202122557241.4" and the name is "An automatic filling equipment". After internal research, the company found that the automatic filling equipment has the following shortcomings:

[0003] (1) The rotating shaft of the conveyor pulley is offset at 45° relative to the horizontal workbench, which requires more materials to be used in the conveyor, making assembly and debugging more difficult and more expensive;

[0004] (2) The packaging tube is positioned and clamped by a complex quick fixture, which results in high costs and difficulty in adapting to packaging tubes of different diameters, resulting in poor versatility of the equipment;

[0005] (3) The motor of the filling component and the screw driving the extrusion cylinder are connected by a traditional reducer, which makes assembly and debugging difficult;

[0006] (4) The feeding device uses a packaging barrel receiving turntable to realize feeding one by one, which is easy to be short of material in actual use, reducing work efficiency;

[0007] (5) The capping device uses a cap receiving turntable to realize feeding one by one, which is prone to leakage in actual use, reducing work efficiency;

[0008] (4) The unloading mechanism is stacked inside the conveying device, which makes debugging difficult in the event of a fault.

The automatic filling equipment for packaging tubes of the present invention cyclically conveys the packaging tube positioning assembly for positioning the packaging tube through a dedicated packaging tube conveying device, automatically loads empty packaging tubes through a loading device, automatically fills materials through a filling device, automatically caps and seals through a capping device, and unloads the filled and capped packaging tubes through an automatic unloading device. The equipment can actively complete the filling and sealing of materials, and has the advantages of a high degree of automation and high work efficiency.

[0022] 2. The dedicated conveying device for packaging tubes includes: a pulley, a belt, and a motor A. A packaging tube positioning assembly is provided on the belt, and the rotating axis of the pulley is perpendicular to the horizontal workbench, so that the packaging tube positioned on the packaging tube positioning assembly always remains facing upward. It has the advantages of simple structure, low cost, and easy debugging.

[0023] 3. The dedicated conveying device for packaging tubes has the following advantages: (1) The packaging tube positioning assembly has the advantages of simple structure and low cost; (2) The positioning sleeve and the positioning frame are detachably connected. When it is necessary to adapt to packaging tubes of other diameters, it is only necessary to adapt the positioning sleeve of the corresponding model. In addition, the positioning sleeve adopts a public mold, which has the advantage of low cost; (3) The straightening guide rail can support the positioning frame so that the packaging tube on the packaging tube positioning assembly always remains horizontal and upward, which can improve the balance of the packaging tube positioning assembly, reduce the radial tension caused to the belt, increase the service life of the belt, and ensure the conveying accuracy; (4) The support rail supports the bottom of the packaging tube, which can reduce the friction of the packaging tube and facilitate subsequent unloading.

[0024] 4. When the packaging tube translation material receiving assembly is in use, as the linear drive drives the material receiving rack to reciprocate, the support part and the material receiving port of the material receiving rack will alternately move to the outlet of the packaging tube guide rack. When the material receiving port is facing the outlet of the packaging tube guide rack, the packaging tube in the packaging tube guide rack will fall into the material receiving port; when the support part is facing the outlet of the packaging tube guide rack, the support part can support the packaging tube in the packaging tube guide rack, so that the packaging tubes can be taken out from the packaging tube guide rack one by one without missing any and not easily getting stuck.

[0025] 5. When the packaging tube flipping and transferring assembly is in use, the clamping claw assembly A of the packaging tube flipping and transferring assembly first clamps the packaging tube that falls into the receiving port, and then the flip seat is driven by the flip seat driver to flip to the top of the packaging tube positioning assembly that moves to the loading station. Then the first lifting seat driver moves downward, the clamping claw assembly A opens, and the packaging tube enters the packaging tube positioning assembly that moves to the loading station, so that the packaging tube can be quickly clamped and transferred from the packaging tube in the receiving port to the packaging tube positioning assembly that moves to the loading station.

[0026] 6. When the filling device is filling, the packaging tube is first clamped by the first auxiliary positioning component and moved upward to align the packaging tube with the filling head before filling; when the filling is completed, the filling head is driven to rotate by the filling head driving component. When the packaging can is filled, the material can be quickly cut off by driving the filling head to rotate, avoiding the material from being "connected" between the packaging tube and the filling head.

[0027] 7. When assembling the motor B and the lead screw of the filling assembly, first insert the upper end of the lead screw into the coupling transmission hole B, and lock the special reducer on the frame. Then, insert the output shaft of motor B into the coupling transmission hole A, and lock motor B on the upper half shell. The assembly between the special reducer, the lead screw and the motor B is completed. Compared with the existing coupling, the structure is simple and the assembly efficiency is high.

[0028] 8. The automatic unloading device is not overlapped with other components, and has the advantages of simple structure and easy maintenance.

During blanking, the finger cylinder 712 first separates the two sets of support rails 36. The packaging tube 1000 between the two support slides 711 will fall from the drop port 2001 and enter the blanking guide 72. The packaging tube then slides along the blanking guide 72 onto the positioning block 734 on the conveyor belt 733 and is then transported downward. The automatic blanking device does not overlap with other components and has the advantages of simple structure and easy maintenance.

[0058] A buffering and resetting mechanism 74 is provided on the outer side of the conveyor belt 733 to prevent the packaging tube 1000 from sliding off the positioning block 734 after entering the positioning block 734. The buffering and resetting mechanism 74 comprises a baffle 741 rotatably connected to the frame 1, and a balancing weight 742 is provided on the outer side of the baffle 741. When a packaging tube slides along the blanking guide 72 and enters the positioning block 734, it first hits the baffle. The balancing weight on the baffle then, due to gravity, pulls the packaging tube back along its original path, ensuring that the packaging tube automatically returns to its original position after falling.

[0059] In this embodiment, a coding assembly 75 for coding the outer side of the finished product is provided at the tail end of the conveyor belt assembly 73 and is used for coding the packaging tube.

[0060] The above examples are merely provided to further illustrate the technical content of the present invention for easier understanding by the reader, but do not limit the embodiments of the present invention to these examples. Any extension or re-creation of the technology based on the present invention is protected by the present invention. The scope of protection of the present invention shall be determined by the claims.
