Description

Technical Field

[0001] This utility model belongs to the field of fire-retardant packaging technology, and in particular relates to a fire-retardant packaging filling mechanism. Background Technology

[0002] During the production or packaging of fire-retardant bags, the filling material needs to be quantitatively added to the packaging according to a certain amount. In the existing technology, manual or simple hopper feeding methods are commonly used, which makes it difficult to accurately control the amount of filling each time. This can easily lead to excessive feeding at one time, resulting in spillage and waste or uneven filling. At the same time, during the actual filling process, the outlet is often blocked due to material accumulation, requiring frequent manual intervention to clean it, which reduces production efficiency and affects the filling quality. Utility Model Content

[0003] This utility model provides a fire-retardant packaging filling mechanism, which aims to solve the problem.

[0004] This utility model is implemented as follows: a fire-retardant packaging filling mechanism includes: a base and a connecting cylinder, the connecting cylinder is installed on the base, a hopper is installed on the connecting cylinder, a discharge nozzle is fixedly connected to one side of the connecting cylinder, a scraping device is assembled inside the connecting cylinder, and a pushing device is assembled on the base.

[0005] The scraping device includes a first electric push rod and a rotating plate. A rotating rod is connected through the rotating plate. A scraping cylinder is fixedly connected to one end of the rotating rod. A scraping hole is opened in the scraping cylinder. The scraping cylinder is rotatably connected to the connecting cylinder.

[0006] Preferably, a locking rod is connected through the rotating plate, a sleeve is provided on the locking rod, a connecting rod is fixedly connected to the outside of the sleeve, and the connecting rod is fixedly connected to the output end of the first electric push rod.

[0007] Preferably, a rotating shaft is fixedly connected to one side of the first electric push rod, and a connecting seat is provided on the outer sleeve of the rotating shaft. The rotating shaft and the connecting seat form a rotatable connection, and the connecting seat is fixedly connected to the upper surface of the base.

[0008] Preferably, the pushing device includes a vertical plate, which is fixedly connected to the base. A second electric push rod is fixedly connected to one side of the vertical plate, and a pushing block is fixedly connected to the output end of the second electric push rod.

[0009] Preferably, an air cylinder is connected through the vertical plate, a piston is installed inside the air cylinder, a push rod is fixedly connected to one side of the piston, and the push rod is fixedly connected to one side of the push block.

[0010] Preferably, a slider is fixedly connected to the lower part of the push block, and a sliding frame is slidably connected to the outside of the slider, with the sliding frame fixedly connected to the upper surface of the base.

[0011] Preferably, a one-way air inlet valve is installed inside the piston, and a one-way air outlet valve is installed at the output end of the air cylinder, with the one-way air outlet valve fixedly connected inside the connecting cylinder.

[0012] Compared with related technologies, the fire-retardant packaging filling mechanism provided by this utility model has the following beneficial effects:

[0013] 1. In this utility model, by setting a scraping device, quantitative and stable material output can be achieved. When the operator starts the first electric push rod, the first electric push rod drives the connecting rod at its output end to move back and forth. The connecting rod pushes the outer sleeve, which in turn drives the internal locking rod to move synchronously. The locking rod is installed inside the rotating plate. When it moves, it drives the rotating plate to rotate. The rotating plate then drives the scraping cylinder to rotate inside the connecting cylinder through the rotating rod inside. During the rotation of the scraping cylinder, the scraping hole on its cylinder body contacts the material below the hopper, realizing continuous scraping of material and quantitative discharge through the discharge nozzle. Since the scraping amount driven by each rotation is limited by the volume of the scraping cylinder and the area of ​​the scraping hole, the problem of material overflow or spillage caused by excessive material discharge at one time in the traditional feeding method is avoided.

[0014] 2. In this utility model, when the scraper hole is in a horizontal ventilation state, the air cylinder can push the air in the connecting cylinder through the internal piston. When the operator starts the second electric push rod, the push rod drives the push block to move along the slide rail. The push block simultaneously drives the push rod and piston connected to its side to make a linear pushing action in the air cylinder. The movement of the piston quickly pushes the air in the air cylinder into the connecting cylinder through the one-way air outlet valve, forming a stable airflow. This blows the residual material on the inner wall of the connecting cylinder and the discharge nozzle, ensuring that the material is smoothly discharged from the discharge nozzle. This structure effectively prevents the blockage caused by material accumulation and improves the reliability of continuous operation and the efficiency of equipment use. Attached Figure Description

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a fire-retardant packaging filling mechanism, such as... Figure 1-4 As shown, it includes: a base 1 and a connecting cylinder 2. The connecting cylinder 2 is installed on the base 1. The hopper 3 is installed on the connecting cylinder 2. A discharge nozzle 4 is fixedly connected to one side of the connecting cylinder 2. A scraping device 5 is assembled inside the connecting cylinder 2. A pushing device 6 is assembled on the base 1.

[0023] The scraping device 5 includes a first electric push rod 503 and a rotating plate 505. A rotating rod 506 is connected through the rotating plate 505. One end of the rotating rod 506 is fixedly connected to a scraping cylinder 507. A scraping hole 508 is opened in the scraping cylinder 507. The scraping cylinder 507 is rotatably connected to the connecting cylinder 2.

[0024] In a further preferred embodiment of this utility model, a locking rod 509 is connected through the rotating plate 505, a sleeve 510 is provided on the locking rod 509, a connecting rod 504 is fixedly connected to the sleeve 510, the connecting rod 504 is fixedly connected to the output end of the first electric push rod 503, a rotating shaft 502 is fixedly connected to one side of the first electric push rod 503, a connecting seat 501 is provided on the rotating shaft 502, the rotating shaft 502 and the connecting seat 501 form a rotatable connection, and the connecting seat 501 is fixedly connected to the upper surface of the base 1.

[0025] In this embodiment, the scraper cylinder 507 has multiple scraping holes 508 inside. When the scraper cylinder 507 rotates with the rotating rod 506, the scraping holes 508 intermittently communicate with the bottom of the hopper 3 to achieve segmented scraping of the material. This structure can achieve quantitative material discharge with each rotation, controlling the discharge amount while preventing continuous material leakage that could lead to waste or overflow. One end of the rotating rod 506 is fixedly connected to the scraper cylinder 507, and the other end passes through the rotating plate 505 and is driven by the first electric push rod 503. This can drive the scraper cylinder 507 to rotate inside the connecting cylinder 2. This relationship realizes the force transmission path from the first electric push rod 503 to the scraping action. The structure is compact and the response is sensitive, which helps to achieve fast and stable scraping control.

[0026] In a further preferred embodiment of this utility model, the pushing device 6 includes a vertical plate 601, which is fixedly connected to the base 1. A second electric push rod 602 is fixedly connected to one side of the vertical plate 601. A pushing block 603 is fixedly connected to the output end of the second electric push rod 602. An air cylinder 604 is connected through the vertical plate 601. A piston 605 is installed inside the air cylinder 604. A pushing rod 606 is fixedly connected to one side of the piston 605. The pushing rod 606 is fixedly connected to one side of the pushing block 603. A slider 607 is fixedly connected below the pushing block 603. A sliding frame 608 is slidably connected to the outside of the slider 607. The sliding frame 608 is fixedly connected to the upper surface of the base 1. A one-way air inlet valve is installed inside the piston 605. A one-way air outlet valve is installed at the output end of the air cylinder 604 and is fixedly connected inside the connecting cylinder 2.

[0027] In this embodiment, a push rod 606 is fixedly connected to one side of the piston 605. When the push block 603 moves back and forth under the drive of the second electric push rod 602, it drives the push rod 606 to slide synchronously, thereby driving the piston 605 to move inside the air cylinder 604. This cooperation accurately converts the electric driving force into air pressure change, which is the key power source for airflow output and ensures the smooth execution of subsequent blowing functions. A slider 607 is provided below the push block 603. The slider 607 is nested in the slide frame 608 to realize linear guided movement along the trajectory of the slide frame 608. This cooperation structure can limit the movement of the push block 603 in one direction, prevent deviation or jamming, and improve the stability and transmission efficiency of the entire push mechanism.

[0028] In summary, when the operator activates the first electric push rod 503, the first electric push rod 503 drives the connecting rod 504 at its output end to move back and forth. The connecting rod 504 pushes the outer sleeve 510, which in turn drives the internal locking rod 509 to move synchronously. The locking rod 509 is installed inside the rotating plate 505. When it moves, it drives the rotating plate 505 to rotate. The rotating plate 505 then drives the scraper cylinder 507 to rotate inside the connecting cylinder 2 through the rotating rod 506 inside it. During the rotation of the scraper cylinder 507, the scraping hole 508 on its cylinder body contacts the material below the hopper 3, realizing continuous scraping of material, and quantitative discharge through the discharge nozzle 4. When the scraper hole 508 is in a horizontal ventilation state, the air cylinder 604 can push the air in the connecting cylinder 2 through the internal piston 605. When the operator starts the second electric push rod 602, the push rod 606 drives the push block 603 to move along the slide rail. The push block 603 simultaneously drives the push rod 606 and piston 605 connected to its side to make a linear pushing action in the air cylinder 604. The movement of the piston 605 quickly pushes the air in the air cylinder 604 into the connecting cylinder 2 through the one-way air outlet valve, forming a stable airflow, which blows the residual material on the inner wall of the connecting cylinder 2 and the discharge nozzle 4 to ensure that the material is smoothly discharged from the discharge nozzle 4.
