Description

Technical Field

[0001] This utility model relates to the field of packaging machines, specifically to a packaging machine and its feeding device. Background Technology

[0002] In existing packaging machines, material is fed from a material hopper to a receiving tray and from a material cup to a receiving hopper below. For example, in a high-speed packaging machine and its feeding device disclosed in CN 219339794 U on July 14, 2023, the material enters the material cup through a sweeping component in the housing. When the sweeping component passes the material cup, the material is level with the cup opening. After the sweeping component passes the cup, the material in the cup falls, resulting in the material being below the cup opening. This means that the packaging bag does not receive the predetermined amount of material. Therefore, there is an urgent need for a feeding structure that keeps the material level with the cup opening after the sweeping component passes through the cup. Utility Model Content

[0035] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0036] As shown in the figure, a feeding device for a packaging machine includes a support 1, a material bucket 2 mounted on the support 1, and a receiving tray 3 located below the material bucket 2. The receiving tray 3 is provided with a plurality of material cups 31 arranged circumferentially. The support 1 is equipped with a feeding seat 4 and a scraping mechanism 5 communicating with the material bucket 2. The feeding seat 4 and the scraping mechanism 5 correspond to the rotation path of the material cups 31. The bottom of the feeding seat 4 is provided with a discharge channel 42 on the side facing the scraping mechanism 5. The feeding seat 4 is also provided with a material control component that controls the material flow by vertically adjusting the cross-sectional area of ​​the discharge channel. In this technical solution, the material in the material bucket enters the feeding seat, and then the material is discharged through the material cups as the receiving tray rotates. A portion of the material in the feeding seat will be discharged from the discharge channel to the outside of the feeding seat. The scraping mechanism collects this material and scrapes it into the material cups, realizing the function of replenishing material. It has the advantages of good replenishing effect and good practicality.

[0037] The material control component includes:

[0038] Adjustment block 41 is vertically slidably installed in the feeding seat 4;

[0039] The adjusting screw 43 is threadedly engaged with the adjusting block 41.

[0040] The driving component is mounted on the feeding seat 4 and is linked to the adjusting screw 43;

[0041] The adjusting block 41 is inserted into the discharge channel 42. The driving component drives the adjusting block to move up and down through the adjusting screw. The height of the adjusting block determines the flow rate of the material in the discharge channel. When the adjusting block descends, less material flows out of the discharge channel, and when the adjusting block rises, more material flows out of the discharge channel.

[0042] In addition, such as Figure 4 As shown in the figure, the adjustment block is inserted into the discharge channel, which is a long strip that connects the inside and outside of the feeding seat.

[0043] The driving component includes a reduction gearbox 44 and a handwheel 45. The reduction gearbox 44 is linked to the handwheel 45 and the adjusting screw 43. The operator rotates the handwheel, which in turn drives the adjusting screw to rotate through the reduction gearbox.

[0044] The scraping mechanism 5 includes a scraper 46 that is in close contact with the upper surface of the receiving tray 3. The scraper 46 has a protrusion 47 at its bottom for scraping material. Figure 3 As shown, the boss is V-shaped, which can gather the material in the middle and scrape it into the material cup.

[0045] The scraping mechanism 5 further includes:

[0046] The scraper 51 is rotatably mounted on the bracket 1;

[0047] The first driving component 52 is fixedly installed at one end of the scraper frame 51 and its output end is connected to the scraper 46.

[0048] A plunger adjusting block 53 is fixedly installed on the bracket 1;

[0049] The knob plunger 54 has its lower end passing through the other end of the scraper frame 51 and inserted into the plunger adjusting block 53. The first driving component is a cylinder, hydraulic cylinder or linear motor, which can drive the scraper on the scraper frame to rise and fall. When working, the scraper is driven by the first driving component to a position that fits against the surface of the receiving tray. When not working and disassembly is required, the scraper can be raised by the first driving component, and then the knob plunger can be pulled out from the plunger adjusting block to allow the scraper frame to rotate around the hinge point, so that the scraper moves away from the top of the receiving tray, making it convenient to disassemble the receiving tray.

[0050] The bottom periphery of the feeding seat 4 is provided with an embedded scraper pad 48. The scraper pad 48 is hollowed out at the position corresponding to the discharge channel 42 to guide the material into the material cup. Figure 4As shown, the scraper pad surrounds the bottom of the feeding seat and scrapes the material into the material cup. One end of the scraper pad is hollowed out to guide the material into the material cup, so that the discharge channel can connect the inside and outside of the feeding seat and allow the material in the feeding seat to be discharged.

[0051] A communication component is also provided between the material hopper 2 and the feeding seat 4. The communication component includes:

[0052] A support plate 61 is mounted on the bracket 1 and has an opening at its end;

[0053] A conveying pipe 62 is disposed between the support plate 61 and the feeding seat 4;

[0054] The feeding seat 4 is provided with a pipe body 49 that connects to the conveying pipe 62. The material bucket 2, the support plate 61, the conveying pipe 62 and the pipe body 49 are connected in sequence to form a channel for material to fall. It has good fluidity. The material enters the feeding seat from the material bucket through the channel. In this technical solution, there are two forms of material: powder and granular material. Powdered material tends to stick to the wall and does not fall, while granular material does not have this problem. Therefore, different communication components of different embodiments are required for different materials.

[0055] Example 1: Mounting rings 66 are provided on the upper and lower sides of the end of the support plate 61. The pipe body 49 and the conveying pipe 62, the conveying pipe 62 and the lower mounting ring, and the bottom of the material bucket 2 and the upper mounting ring are connected in sequence, and clamps 67 for fixing are provided at each connection position. This example is suitable for granular materials. The material falls directly through the channel, and the clamps can ensure the stability of the connection.

[0056] Example 2: Mounting rings 66 are provided on the upper and lower sides of the end of the support plate 61. The pipe body 49 and the conveying pipe 62 are sequentially connected, and the conveying pipe 62 and the mounting ring on the lower side are connected in sequence. Clamps 67 for fixing are provided at each connection position. A second driving component is provided between the support plate 61 and the material bucket 2. The second driving component adopts a motor 63 and a reducer 64. The output end of the reducer 64 is provided with a rotating rod 65 set in the channel and used to scrape off the material in the channel. This example is suitable for powdery materials. When the rotating rod rotates, it will scrape off the material on the inner wall of the channel, ensuring the stable feeding of the material.

[0057] The present invention also provides another technical solution, a packaging machine, which includes a film-joining device 71, a packaging bag forming device 72, a longitudinal sealing device 73, a sealing device 74, a filling device 75, and a finished product output device 76, and further includes a feeding device as described above located above the filling device 75, having all the beneficial effects of the feeding device described above.
