Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a feeding mechanism of a particle packer and the particle packer. Background Art

[0002] The granule packer is a modern packaging device widely used in the packaging of various granular materials. Its high efficiency, precision, and stability have strongly supported the development of my country's packaging industry. The granule packer's operating principle primarily involves four steps: material measurement, bag opening, material filling, and bag sealing. First, a measuring system accurately measures the material to ensure consistent weight each time it is filled. Then, a control system controls the filling speed and quantity based on the set bag weight and the measurement results. Next, a bag opener opens the bag to allow the material to be poured into it. Finally, a sealing device seals the bag, completing the packaging process.

[0003] The feeding of the pellet packer is mainly carried out by conveying the pellets from the raw material warehouse or the front end of the production line to the packaging equipment. Generally, the appropriate conveying equipment is selected according to the properties of the pellets and production requirements, such as belt conveyors, bucket elevators, vibrating conveyors, etc.

[0004] The patent "Large Bag Granule Packaging Machine" (authorization publication number CN219790701U, hereinafter referred to as Prior Art 1) discloses a packaging machine. Prior Art 1 utilizes a material barrel and four clamping plates to support the packaging bag, facilitating the collection of granular material. A solenoid valve controls the opening and closing of a flow guide tube, facilitating the controlled flow of granular material and allowing for the delivery of granular material of varying weights within the bag. Furthermore, a multi-stage telescopic hydraulic cylinder drives the flow guide tube to slowly ascend from the bottom of the bag cavity, allowing the granular material to first fill the bottom of the bag before gradually adding more material upwards. This prevents excessive impact from the granular material being discharged, which could damage the bag. Furthermore, a servo motor drives the rotation of a stirring paddle, which disperses the granular material within the packaging machine's main body, preventing it from clumping and impacting packaging efficiency. This machine requires no manual operation, saving time and effort. After packaging is complete, the operator pulls the material barrel to the front of the base, sequentially loosens the four clamping plates, and seals the bag's opening. In the prior art 1, the feed is easily blocked, so an additional stirring device is used to stir the material. However, the feed still needs to be packaged through a material pipe, and the material may accumulate and block in the material pipe, making it difficult to discharge. Utility Model Content

[0031] Embodiment 1

[0032] Please refer to Figure 1 , the embodiments of the present utility model provide a blanking mechanism for a particle wrapper, which includes a material box 100 and a storage cavity 110 provided inside the material box 100; the storage cavity 110 is provided in a through manner. The top of the storage cavity 110 is a feed inlet 120; the bottom of the storage cavity 110 is a discharge outlet 130. A first material limiting plate 140 and a second material limiting plate 150 are respectively provided on both sides of the discharge outlet 130.

[0033] Please refer to Figure 1 and Figure 3 , the inside of the material box 100 is provided in a through and hollow manner and is provided with a storage cavity 110. When the inside of the material box 100 is through, the internal storage cavity 110 cannot complete the separate storage work. The storage cavity 110 is closed by the following first material gate 310 and second material gate 320 to assist in its storage. The discharge outlet 130 and the feed inlet 120 are through, so that the material is not easily blocked during feeding, and the blanking speed is relatively fast. The feed inlet 120 is provided with a relatively large opening diameter, so that a high efficiency can be maintained when feeding materials into the storage cavity 110.

[0034] Please refer to Figure 2 or Figure 5 , on both sides of the fuselage of the bin 100, a first blanking cylinder 210 and a second blanking cylinder 220 are respectively provided; the bottoms of the first blanking cylinder 210 and the second blanking cylinder 220 are respectively connected with a first material gate 310 and a second material gate 320 through a first hinge part and a second hinge part. Since the first material gate 310 and the second material gate 320 are arranged on the bin 100 and the discharge port 130 is closed, and their opening and closing are controlled by the cooperation of the cylinder and the following components, when the first material gate 310 and the second material gate 320 are opened, there may be gaps at their joints, causing material leakage. Therefore, a first material limiting plate 140 and a second material limiting plate 150 are provided. The first material limiting plate 140 and the second material limiting plate 150 are arranged in an inclined manner. Firstly, it makes up for the part where there may be gaps when the first material gate 310 and the second material gate 320 are opened. Secondly, it can guide the material to be discharged from the positions of the first material gate 310 and the second material gate 320.

[0035] The first material gate 310 and the second material gate 320 are respectively arranged on one side of the bin 100 adjacent to the first material limiting plate 140 and the second material limiting plate 150. When the first material gate 310 and the second material gate 320 are closed, the discharge cavity is closed by the four-sided cooperation with the first material limiting plate 140 and the second material limiting plate 150, making it impossible for the bin 100 to leak materials.

[0036] Please refer to Figure 1 , the first material gate 310 and the second material gate 320 are respectively hinged to both sides of the bin 100; the first blanking cylinder 210 and the second blanking cylinder 220 form a control through their hinge parts with the first material gate 310 and the second material gate 320. When the first material gate 310 and the second material gate 320 are to be opened, the piston rods 211 of the first blanking cylinder 210 and the second blanking cylinder 220 extend downward. Through the hinge of the first material gate 310 and the second material gate 320 with the bin 100, the ends of the first material gate 310 and the second material gate 320 are in an open state for material leakage. The longer the piston rods 211 extend, the farther the positions where the first material gate 310 and the second material gate 320 are pushed out, and the faster the material leakage speed. When the first material gate 310 and the second material gate 320 are in a natural vertical state, due to gravity and the hinge with the bin 100, the ends of the first material gate 310 and the second material gate 320 are in a closed state. At this time, the piston rods 211 reinforce their closed state. The piston rods 211 contract upward. At this time, the first material gate 310 and the second material gate 320 are in a clamped closed state, making the materials in the bin 100 unable to leak out.

[0037] Please refer to Figure 2 or Figure 5 , the first blanking cylinder 210 and the second blanking cylinder 220 are respectively installed through the first cylinder mounting plate 230 and the second cylinder mounting plate 240. The first blanking cylinder 210 and the second blanking cylinder 220 are respectively arranged on both sides of the material box 100 and are respectively installed through the first cylinder mounting plate 230 and the second cylinder mounting plate 240 fixed on the material box 100. The first blanking cylinder 210 and the second blanking cylinder 220 can be stably arranged on the material box 100. Both the first cylinder mounting plate 230 and the second cylinder mounting plate 240 are in an "L" shape, and a boss for setting the first blanking cylinder 210 and the second blanking cylinder 220 is formed at the bottom, and the first blanking cylinder 210 and the second blanking cylinder 220 are fixed on it.

[0038] Please refer to Figure 1 , the first door 310 and the second door 320 surround the discharge port 130; the first door 310 and the second door 320 control the first hinge part and the second hinge part to open and close through the first blanking cylinder 210 and the second blanking cylinder 220. When the first blanking cylinder 210 and the second blanking cylinder 220 directly push the box door, when the first door 310 and the second door 320 are directly stressed, the moment arm is short and it is not easy to push the first door 310 and the second door 320, so the first hinge part and the second hinge part are provided to assist in pushing the first door 310 and the second door 320 respectively.

[0039] Furthermore, a particle wrapper is also provided, including a blanking mechanism as described above, and the particle wrapper is packaged through the blanking of the blanking mechanism; the ends of the first door 310 and the second door 320 are provided with sharp corners, which are convenient for joining with the packaging bag of the particle wrapper and make it easier to discharge the internal material into the packaging bag. And the sharp corner settings at the ends of the first door 310 and the second door 320 can increase the opening of the packaging bag with a smaller opening, enabling more efficient packaging work.

[0040] Embodiment 2

[0041] Please refer to Figure 1 0, the embodiment of the present utility model provides a blanking mechanism of a particle wrapper, and an inclined setting is formed between the first limiting plate 140 and the second limiting plate 150 and the material box 100; the bottoms of the first limiting plate 140 and the second limiting plate 150 are inclined towards the end close to each other.

[0042] Generally speaking, the inclined design can improve the fluidity of materials in the bin 100, avoiding material accumulation and blockage. In this case, the bottoms of the first material limiting plate 140 and the second material limiting plate 150 are inclined towards the end where they approach each other, so that the flow direction and speed of the materials can be better controlled. When the materials enter the bin 100, due to the effect of the inclined plate, they will naturally converge towards one end, facilitating subsequent material discharging. In addition, this design also helps the first material door 310 and the second material door 320 to seal the inside of the storage cavity 110, avoiding material leakage through gaps. Moreover, due to the existence of the inclined plate, the materials inside the bin 100 can exhibit a higher density under the same volume. This means that the limited material storage space can be utilized more efficiently.

[0043] Please refer to Figure 1 , the first material door 310 is formed by folding a plate multiple times. This design can effectively resist the pressure and impact of the internal materials and extend the service life of the material door. The first material door 310 is provided with a joint end 311 and a material discharging end 312; the first material door 310 and the second material door 320 are arranged in the same way. The first material door 310 has two important ports, namely the joint end 311 and the material discharging end 312. The joint end 311 is mainly responsible for connecting with the bin 100 to ensure the integrity of the entire bin 100. The material discharging end 312 is responsible for controlling the flow and discharging of the materials to ensure the smooth progress of the packaging process. The design of the first material door 310 is also consistent with that of the second material door 320, achieving seamless cooperation between the two, thereby improving the overall working efficiency. In this way, the two material doors can work together to meet various packaging requirements.

[0044] Please refer to Figure 1 , the material discharging ends 312 of the first material door 310 and the second material door 320 are inclined towards the end where they approach each other; when the ends of the first material door 310 and the second material door 320 approach each other, the discharge port 130 is closed. Through the inclined setting of the first material door 310 and the second material door 320, the friction and resistance of the materials during transportation can be reduced, energy loss can be decreased, and the transportation efficiency can be improved. It is beneficial to the rapid discharge of the materials and avoids transportation blockage caused by material accumulation. And when the ends of the first material door 310 and the second material door 320 approach each other and their inclined ends are joined, the discharge port 130 can be completely closed.

[0045] Please refer to Figure 2 、 Figure 4 and Figure 5, the first hinge part includes a first connecting member 411, a first connecting shaft 412, a first hinge plate 413 and a second hinge plate 414. The second hinge part includes a second connecting member 421, a second connecting shaft 422, a third hinge plate 423 and a fourth hinge plate 424. The first hinge part and the second hinge part are arranged identically. The first hinge part and the second hinge part form a mechanism through the above components to assist the first material door 310 and the second material door 320 in rotating. The same sides of the first material door 310 and the second material door 320 are respectively connected to the first blanking cylinder 210 and the second blanking cylinder 220 through the first hinge plate 413 and the second hinge plate 414, the third hinge plate 423 and the fourth hinge plate 424.

[0046] Preferably, mating holes 419 are respectively provided at both ends of the first hinge plate 413 and the second hinge plate 414; the mating holes 419 at one end of the first hinge plate 413 and the second hinge plate 414 are hinged to the connection holes 418 of the first connection end 415 through the first connecting shaft 412. The first hinge plate 413 and the second hinge plate 414 are respectively hinged to the same side of the first material door 310 and the second material door 320, and the third hinge plate 423 and the fourth hinge plate 424 are respectively hinged to the other side of the first material door 310 and the second material door 320. The tops of the first hinge plate 413 and the second hinge plate 414 after being hinged to the first material door 310 and the second material door 320 are in contact, and the bottoms are respectively hinged to the first material door 310 and the second material door 320.

[0047] Please refer to Figure 1 , both sides of the first material door 310 and the second material door 320 are connected to both sides of the first hinge plate 413 and the second hinge plate 414 and the material box 100 through two connection positions; the first material door 310 and the second material door 320 are rotatably connected to the first hinge plate 413 and the second hinge plate 414, and the first material door 310 and the second material door 320 are rotatably connected to the material box 100. When the piston rod moves, it drives the rotational connection between the first material door 310 and the second material door 320 and the first hinge plate 413 and the second hinge plate 414, thereby driving the rotational connection between the first material door 310 and the second material door 320 and the material box 100, so that the first material door 310 and the second material door 320 are opened or closed.

[0048] Please refer to Figure 2 , mounting holes 313 adapted to the mating holes 419 are respectively provided at the joint ends 311 of the first material door 310 and the second material door 320; the first material door 310 and the second material door 320 are respectively hinged to the first hinge plate 413 and the second hinge plate 414, the third hinge plate 423 and the fourth hinge plate 424 through the mounting holes 313.

When the piston rods 211 of the first blanking cylinder 210 and the second blanking cylinder 220 extend, through the hinges between the first hinge plate 413 and the second hinge plate 414, the third hinge plate 423 and the fourth hinge plate 424 and the piston rods 211, the first hinge plate 413 and the second hinge plate 414, the third hinge plate 423 and the fourth hinge plate 424 are driven downward.

When the piston rod 211 contracts, the first hinge plate 413 and the second hinge plate 414, the third hinge plate 423 and the fourth hinge plate 424 are driven to rotate upward, thereby driving the material gate to rotate based on the material box 100, so that the first material gate 310 and the second material gate 320 are closed.
