Description

Technical Field

[0001] This utility model relates to the field of quantitative packaging structures, specifically a multi-channel quantitative packaging mechanism. Background Technology

[0002] A channel refers to the area where materials participate in combined weighing. Commonly used channel numbers include single-channel, dual-channel, triple-channel, four-channel, and five-channel. Existing technology combines multiple channels onto the same machine, such as... Figure 1 As shown, each channel is placed close together, forcing the main vibrator to be positioned as close as possible, resulting in limited space for the main vibrator plate mounted on it. Therefore, multi-channel main vibrator plates are mostly fan-shaped structures. Figure 7 As shown in (a), the fan-shaped structure cannot hold a large amount of material. At the same time, the combination of the fan-shaped structure and the main vibrator is not conducive to the movement of material (the main vibrator causes the material to spread along the circumference), resulting in material jamming and uneven material distribution in terms of flowability. Utility Model Content

[0003] The purpose of this invention is to provide a multi-channel quantitative packaging mechanism to solve the problems of easy material jamming, uneven material distribution, and inconvenience in use of existing multi-channel feeding and weighing equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-channel quantitative packaging mechanism, comprising multiple weighing channels, wherein the weighing channels include: The feed hopper, installed on the frame, is used to receive materials conveyed by the upper-level equipment; The main vibrating plate is located below the feed hopper and is used to vibrate and disperse the material so that the material is evenly dispersed. V-shaped linear vibratory feeders are set around the main vibratory feeder to catch materials falling from the main vibratory feeder. The weighing hopper assembly is located at the outlet of the V-shaped vibrating disc and is used for weighing and measurement. An inclined guide trough is installed at the outlet of the weighing hopper assembly; The center-to-center distance between any two main oscillators shall be at least twice the radius of the main oscillator.

[0005] As a further improvement to the above technical solution: The main vibrating plate includes a conical plate and a vibrating structure, which are connected to the conical plate. The cone angle of the conical plate ranges from 100° to 175°. The cone angle range is selected according to the material conditions to ensure that the material can move towards the edge and fall onto the V-shaped vibrating plate under the vibration of the vibrating structure.

[0006] A baffle is provided on the edge of the cone disk, and the baffle is located on the side where the V-shaped oscillator is not installed.

[0007] A buffer hopper assembly is provided between the V-shaped linear vibrating plate and the weighing hopper assembly. The buffer hopper assembly can avoid the problem of inaccurate weighing data caused by the direct drop of materials. By using the buffer hopper assembly for buffering, the material drops without initial velocity, ensuring the accuracy of the weighing data.

[0008] The number of weighing channels is 3-5.

[0009] The lower parts of the multiple inclined guide grooves converge at the branch outlet.

[0010] The inclined guide grooves of the multiple weighing channels converge to the main outlet.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The main vibratory plate features ample design space and enhanced adaptability: by setting the center distance between any two main vibratory plates to at least twice their radius, the design limitations caused by space constraints in traditional mechanisms are completely overcome. The main vibratory plate is designed as a complete circle, which on the one hand ensures more even force distribution on the material during vibration, allowing for full dispersion on the conical plate surface, significantly reducing the risk of material accumulation and blockage, and enabling smoother material entry into the V-shaped vibratory plate; on the other hand, the complete circular structure significantly increases the material storage capacity of the main vibratory plate, providing continuous and sufficient material support for high-speed weighing, avoiding equipment downtime or speed reduction due to insufficient material supply, and ensuring production continuity from the source. Baffles are installed at the edge of the conical plate, guiding the material towards the edge through a reasonable cone angle, and effectively preventing accidental material drop during vibration, ensuring that the material falls into the V-shaped vibratory plate, further improving the stability and reliability of material conveying. Thanks to the increased space provided by the increased spacing between the main vibrating discs, the number of weighing hoppers that can be arranged in each weighing channel has significantly increased. More weighing hoppers participating in weight combinations greatly improves the success rate of weight matching, and this increased success rate directly drives up the machine's weighing speed, effectively improving overall production efficiency. At the same time, the removal of space constraints means that the weighing hopper volume is no longer limited to small capacities; larger capacity weighing hoppers can be designed according to actual production needs, providing stable assurance for weighing large volumes of materials and broadening the adaptability of the mechanism to different batches of material packaging. The mechanism is equipped with multiple independent weighing channels, and each channel can simultaneously carry out material receiving, vibration dispersion, weighing and conveying operations. Compared with single-channel or multi-channel mechanisms, the overall material handling capacity is increased exponentially. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 2 and Figure 5 As shown, the multi-channel quantitative packaging mechanism of this embodiment has three weighing channels; the weighing channels include: Feed hopper 1, installed on frame body 10, is used to receive materials conveyed by the upper-level equipment; The main vibrating plate 2 is a circular structure and is located below the feed hopper 1. It is used to vibrate and disperse the material so that the material is evenly dispersed. V-shaped vibrating plate 3 is set around the main vibrating plate 2 to catch materials falling from the main vibrating plate 2; Weighing hopper assembly 4 is located at the outlet of V-shaped vibrating plate 3 and is used for weighing and measurement. Inclined guide chute 5 is located at the outlet of weighing hopper assembly 4; The center-to-center distance between any two main oscillating disks 2 must be at least twice the radius of the main oscillating disk 2. For example... Figure 2 The center distance here is 3r, and r is the radius of the main oscillator.

[0019] like Figure 6As shown, Figure (a) is a schematic diagram of the internal structure of an existing multi-channel device, and Figure (b) is a schematic diagram of the internal structure of this utility model. L1 is the distance between vibration centers. Existing multi-channel devices are circular vibrating discs divided into multiple independent vibrating discs with small spacing. Each channel is close together, forcing the main vibration mechanism to be placed as close as possible, resulting in limited space for the main vibrating discs mounted on the main vibrating machine. This leads to material jamming and uneven material distribution in terms of material flow. L2 is the center distance of the vibrating discs. L2 is much larger than L1. By adopting a circular structure, the spacing of the main vibrating discs 2 is increased, giving the main vibrating discs 2 sufficient space. The main vibrating discs 2 can be designed into matching shapes according to different materials. Because there is sufficient space in the position of the main vibrating discs 2, the main vibrating discs 2 can be designed as a complete circle. The circular main vibrating discs 2 make the material more evenly stressed, and the material is fully vibrated on the surface of the main vibrating discs 2. This makes it easier for the material to enter the V-shaped vibrating discs 3, and the increased storage capacity of the main vibrating discs 2 provides sufficient material support for high-speed weighing of the machine. Thanks to the increased spacing between the main vibrating discs 2, the number of hoppers arranged in each channel can be increased. This increased number of hoppers allows for more hoppers to participate in the combination, improving the combination success rate. A higher combination success rate directly leads to a higher weighing speed. Also thanks to the increased spacing between the main vibrating discs 2, the volume of hoppers that can be arranged in each channel is increased. Previously, due to space limitations, the volume of each hopper was limited to a small capacity. This technical solution allows for an increase in hopper capacity, ensuring large-capacity weighing. The main vibrating disc 2 includes a conical disc 21 and a vibration structure 22. The vibration structure 22 is connected to the conical disc 21; therefore, the center-to-center distance of the conical discs 21 is greater than twice the radius. Figure 8 As shown, the cone angle B of the cone disk 21 ranges from 100° to 175°.

[0020] like Figure 7 As shown in Figure (a), the existing fan-shaped main vibrating plate structure has a relatively small load-bearing capacity. Furthermore, the existing vibration structure uses a unidirectional circular vibrator (causing the material to rotate in a single direction along the circle), which makes it difficult for the material to fall from the fan-shaped main vibrating plate. The black dots in the figure represent the material. Figure (b) shows the circular main vibrating plate structure of this invention, which has a large load-bearing capacity and ensures that the material falls quickly and evenly, thus improving the equipment's working efficiency.

[0021] A baffle 23 is provided on the edge of the cone disk 21, and the baffle 23 is located on the side where the V-shaped linear vibrating plate 3 is not provided. The baffle prevents the material from falling. Under the vibration of the vibration structure 22, the material falls from the cone disk 21 onto the V-shaped linear vibrating plate 3.

[0022] In some embodiments, a buffer bucket assembly 6 is provided between the V-shaped linear vibrating plate 3 and the weighing bucket assembly 4. The buffer bucket assembly 6 is used to buffer the impact of the material on the V-shaped linear vibrating plate 3, ensuring the weighing accuracy of the weighing bucket assembly 4. Using multiple weighing bucket assemblies facilitates weight matching. The structure of the weighing bucket assembly is a conventional structure in the market (part of its structure has been disclosed in our company's patent), including a bucket body, an opening and closing door, a controller, a driver, and a drive structure. The drive structure is a multi-link structure that drives the opening and closing door to open and close. The controller sends commands to the driver, causing the driver to drive the multi-link structure to open and close the bucket body. A weight sensor is used for weighing. The controller is also included here to record the weight of the material in each bucket and select the appropriate bucket to release the material according to the preset weight. This combination of technologies is conventional in the field and is not described in detail here. The structure of the buffer bucket assembly 6 is the same as that of the weighing bucket assembly 4. It does not need to have a weighing function; its purpose is to buffer the material to ensure the weighing accuracy of the weighing bucket assembly 4.

[0023] In one embodiment, the lower parts of multiple inclined guide channels 5 converge to the branch outlet 7. Therefore, this provides multiple weighing channels corresponding to multiple outlets, allowing for the individual bagging of different materials.

[0024] In another embodiment, the inclined guide troughs 5 of multiple weighing channels converge to a main outlet. Here, a single outlet or multiple outlets converge to a main outlet, which is mainly used for uniform bagging of materials of different shapes.

[0025] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
