Description

Technical Field

[0001] This utility model relates to the field of quantitative packaging structure, specifically a quantitative discharging device for strip-shaped materials. Background Technology

[0002] When packaging strip-shaped materials in quantitative quantities, the materials need to be weighed and combined for packaging. Due to their special shape, jamming is prone to occur in the combined weighing and metering equipment. Therefore, a material sorting structure needs to be designed to sort the materials and arrange them neatly. The existing structure cannot completely complete the posture correction and sorting (vibration alone cannot guarantee the sorting effect), resulting in some materials still being cross-stacked and arranged messily, directly causing low efficiency in subsequent packaging and processing processes. Utility Model Content

[0003] The purpose of this invention is to provide a quantitative discharge device for strip-shaped materials to solve the problem that the materials are stacked and arranged in a messy manner, which directly leads to low efficiency in subsequent packaging and processing procedures.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quantitative discharge device for strip-shaped materials, comprising: 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. An inclined guide trough is installed at the outlet of the weighing hopper assembly; The feeding unit is located below the inclined guide trough. The feeding unit includes a non-conforming channel, a conforming channel, a screening hopper, and a sorting hopper. The screening hopper is located below the inclined guide trough and is used to receive the combined materials and select the non-conforming channel or the conforming channel for feeding. The sorting hopper is located above the conforming channel.

[0005] As a further improvement to the above technical solution: The sorting hopper includes a hanger, a support plate, a centralized feeding cylinder, a sorting cylinder, and a baffle. The support plate is connected to the hanger, and the hanger is connected to the frame. The support plate is provided with a slide rail assembly and a position change driving assembly. The sorting cylinder is slidably engaged with the slide rail assembly. The position change driving assembly is connected to the sorting cylinder and drives the sorting cylinder to switch positions between the qualified channel and the baffle.

[0006] The main vibrating plate includes a conical plate and a vibration structure, the vibration structure being connected to the conical plate, and the cone angle of the conical plate being in the range of 160°-170°.

[0007] The screening bucket is hinged to the hanger, and a screening drive component is provided between the hanger and the screening bucket. The two ends of the screening drive component are respectively hinged to the hanger and the screening bucket.

[0008] The baffle is mounted on the support plate by a first spring, and a vibrator is provided on the baffle.

[0009] A vibrator is installed on the outer wall of the sorting cylinder. The vibrator is used here to ensure smooth material movement and assist in adjusting the material's posture.

[0010] 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.

[0011] The sorting cylinder is provided with a through groove, and a clamping arm assembly is movably arranged in the through groove. A clamping drive mechanism is provided on the outside of the clamping arm assembly.

[0012] The clamping arm assembly includes two opposing clamping arms, each with cross-arranged comb teeth. Non-fully enclosed clamping arms cannot properly handle all materials in the sorting cylinder, while fully enclosed clamping arms would cause movement interference. Therefore, a cross-arranged comb tooth structure clamping arm is used, allowing the two clamping arms to operate normally when clamping inwards, thus correcting material deviation.

[0013] The clamping arm assembly consists of at least two sets. Typically, there is one set of clamping arms at the top and one set at the bottom of the sorting cylinder. Since the deflection position is at both ends, at least two sets of clamping arms are used for position correction.

[0014] Compared with the prior art, the beneficial effects of this utility model are: Highly efficient dispersion and anti-jamming: The large cone angle design of the main vibrating plate, combined with the vibration structure, ensures uniform material dispersion; the sorting hopper is equipped with a pneumatic vibrator to effectively avoid material blockage and ensure process continuity.

[0015] Innovative sorting mechanism: The sorting cylinder is adjustable in position or features a baffle switch design to adapt to different discharge modes, offering high flexibility. The clamping arm assembly and cross-comb structure achieve all-around wrapping and sorting of strip-shaped materials, solving the problems of cross-stacking and messy arrangement, and ensuring neatness of the output. Through the end-of-line sorting function, neatly arranged materials are directly output, avoiding inefficiencies in subsequent packaging processes caused by messy materials, and significantly improving overall production efficiency.

[0018] 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.

[0020] 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.

[0021] 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.

[0022] like Figures 1 to 3 As shown, the strip-shaped material quantitative discharge device of this embodiment includes: Feed hopper 1, installed on frame body 10, is used to receive materials conveyed by the upper-level equipment; The main vibrating disc 2, located below the feed hopper 1, is used to vibrate and disperse the material, ensuring uniform dispersion. The main vibrating disc 2 includes a conical disc and a vibrating structure connected to it. The cone angle of the conical disc ranges from 160° to 170°. The vibrating structure drives the conical disc to vibrate, causing the material on the disc to disperse and fall off. The vibrating structure is connected to the frame body 10 via springs. The vibrating structure is a commercially available component and is not detailed here.

[0023] The V-shaped linear vibrating plate 3 is located around the main vibrating plate 2 and is used to catch materials falling from the main vibrating plate 2. This structure is a conventional technology in this field and will not be described in detail here.

[0024] Weighing hopper assembly 4 is located at the outlet of V-shaped vibrating plate 3. A buffer hopper assembly 7 is positioned between V-shaped vibrating plate 3 and weighing hopper assembly 4. The purpose of buffer hopper assembly 7 is to catch material falling from above, preventing it from falling directly into the weighing hopper assembly and causing weighing errors. Using multiple weighing hopper assemblies facilitates weight matching. The structure of the weighing hopper assembly is a conventional market structure (part of which has been disclosed in our company's patents), including a hopper body, an opening / closing door, a controller, a driver, and a drive structure. The drive structure is a multi-link structure that drives the opening / 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 hopper body. A weight sensor is used for weighing. The controller is also included here to record the weight of the material in each hopper and selects the appropriate hopper to release the material based on a preset weight. This technology combination is conventional in the field and is not detailed here. The structure of buffer hopper assembly 7 is the same as that of weighing hopper assembly 4, but it does not need to have a weighing function; its purpose is to buffer the material to ensure the weighing accuracy of weighing hopper assembly 4.

[0025] An inclined guide chute 5 is located at the outlet of the weighing hopper assembly 4; the inclined guide chute 5 is used to guide the material to the unloading unit 6. For example... Figure 4 As shown, a centralized feeding cylinder 642 is provided below the inclined guide chute 5, and the feeding unit 6 is connected through the centralized feeding cylinder 642. The centralized feeding cylinder includes an upper unit and a lower unit. The upper unit is used to connect to the inclined guide chute 5, and the lower unit is used to centrally collect materials, merging multiple channels into one channel for material discharge.

[0026] The feeding unit 6 is located below the inclined guide chute 5. The feeding unit 6 includes a non-conforming channel 61, a conforming channel 62, a screening hopper 63, and a sorting hopper 64. The screening hopper 63, located below the inclined guide chute 5, receives the combined material and selects either the non-conforming channel 61 or the conforming channel 62 for feeding. The sorting hopper 64 is located above the conforming channel 62. The screening hopper 63 is hinged to a hanger 640, and a screening drive component 630 is provided between the hanger 640 and the screening hopper 63. Both ends of the screening drive component 630 are hinged to the hanger 640 and the screening hopper 63, respectively. If the weight measured in a single weighing exceeds a pre-set error range, it needs to be discharged. The discharged material is considered non-conforming and is discharged through the outlet of the screening hopper 63 towards the non-conforming channel 61. If the weight is within the pre-set weight error range, the outlet of the screening hopper 63 is directed towards the sorting hopper 64, conveying the product to the sorting hopper 64. The above design is not significantly different from the design in the prior art. However, since the packaging bag is placed directly below the qualified channel 62, the products are not neatly arranged, which cannot guarantee smooth feeding and thus affects production efficiency.

[0027] Based on this, such as Figure 5As shown, the sorting hopper 64 in this embodiment includes a hanger 640, a support plate 641, a centralized feeding cylinder 642, a sorting cylinder 643, and a baffle 644. The support plate 641 is connected to the hanger 640, and the hanger 640 is connected to the frame body 10. A slide rail assembly 645 and a position change drive assembly 646 are provided on the support plate 641. The sorting cylinder 643 is slidably engaged with the slide rail assembly 645. The position change drive assembly 646 is connected to the sorting cylinder 643 and drives the sorting cylinder 643 to switch positions between the qualified channel 62 and the baffle 644. The baffle 644 is mounted on the support plate 641 by a first spring 647, and a vibrator 648 is provided on the baffle 644.

[0028] like Figure 6 and Figure 7 As shown, with Figure 5 The difference in structure is that in this embodiment, the baffle 644 is connected to the position change drive component 646, and the qualified channel 62 is directly set below the sorting cylinder 643. The movement of the baffle acts as a material discharge switch. Due to the simplified structure, a vibrator 648 is provided on the outer wall of the sorting cylinder 643. The vibrator 648 is a pneumatic vibrator, which is used to avoid the situation where material cannot be discharged due to jamming, so that the packaging material can move normally.

[0029] Furthermore, in order to improve the uniformity of the output, such as Figures 8 to 10 As shown, a through groove 6431 is provided on the sorting cylinder 643, and a clamping arm assembly 6432 is movably disposed within the through groove 6431. A clamping drive mechanism 6433 is provided on the outside of the clamping arm assembly 6432. If the through groove 6431 is integral, then part of the clamping arm assembly 6432 is welded to the sorting cylinder 643. (This section does not describe an integral structure.) The clamping drive mechanism 6433 is used to drive the clamping arms to rotate around the hinge point. The clamping drive mechanism 6433 uses a cylinder or a multi-link combined cylinder drive structure. There are at least two clamping arm assemblies 6432. Generally, there is one set at the top and one at the bottom. Since the correction part of the strip-shaped material is at both ends, correction of the middle cannot achieve the correction effect. Using single top correction or single bottom correction cannot guarantee the overall neatness. Therefore, at least two assemblies are provided here. Before clamping, the clamping arm should not protrude from the inner wall of the sorting cylinder 643. The optimal position is flush with the inner wall. Before operation, the clamping arm should be inclined to completely wrap around the material. If it is not completely wrapped, it will be unable to clamp all the material during operation.

[0030] To ensure implementation, such as Figure 11As shown, the clamping arm structure includes two opposing clamping arms with cross-arranged comb teeth. This cross-arranged comb teeth allow for the wrapping of all materials within the sorting cylinder 643, thus enabling the sorting of strip-shaped materials. This solves the problem of materials being stacked and arranged haphazardly, directly causing low efficiency in subsequent packaging and processing steps. The range of motion of the clamping arms should be set according to the dimensions of the material combination. The enclosing dimension formed by the clamping arms must be larger than the dimensions of the material combination to prevent the clamping arms from damaging the materials. The purpose of the clamping arms here is to guide the materials closer together, avoiding a messy situation.

[0031] The working process of this utility model includes: S1. Feeding and Initial Dispersion: The material is conveyed from the upper-level equipment to the feed hopper 1, and then falls into the main vibrating plate 2. The cone of the main vibrating plate 2 vibrates under the drive of the vibrating structure, so that the material is evenly dispersed and falls into the V-shaped linear vibrating plate 3 below.

[0032] S2. Buffering, Conveying, and Weighing: The V-shaped vibrating disc 3 receives the material falling from above and guides it into the buffer hopper assembly 7. The buffer hopper assembly 7 buffers the material, preventing it from falling directly into the weighing hopper assembly and causing weighing errors in the weight sensor due to impact. The controller sends a command to the driver, which drives the multi-link structure to open and close the hoppers. The hoppers receive the material and are weighed in real time by the weight sensor. The controller records the weight of the material in each hopper and compares it with the preset target weight. It selects the hopper with the closest weight to the target weight and opens the hopper gate through the multi-link drive structure, releasing the material into the inclined guide chute 5.

[0033] S3. Qualification Screening and Guiding: The inclined guide chute 5 guides the material to the screening hopper 63. The controller drives the screening drive component 630 based on the weight judgment result: (A pre-set error range is set for the weight of the quantitative weighing; weights within the error range are qualified, and weights exceeding the set error range are unqualified). If the weight is unqualified, the screening hopper 63 turns to the unqualified channel 61 to discharge the material; if it is qualified, it turns to the qualified channel 62, and the material falls into the sorting hopper 64 for sorting.

[0034] S4. Material Sorting and Discharge: Sorting hopper 64 ensures neat material discharge through two methods: Option 1 ( Figure 5 The position change drive assembly 646 drives the sorting cylinder 643 to move between the qualified channel 62 and the baffle 644. When the sorting cylinder 643 is aligned with the qualified channel 62, the material falls in; initially, the outlet of the sorting cylinder 643 is above the baffle 644, and the vibrator 648 is activated to prevent material jamming. The baffle 644 is buffered by the first spring 647 to ensure stability.

[0035] Option 2 ( Figure 6-7The qualified channel 62 is located directly below the sorting cylinder 643, and the baffle 644 is controlled by the position change drive assembly 646 as a switch. The vibrator 648 is directly installed on the outer wall of the sorting cylinder 643 to prevent material jamming.

[0036] Clamping and sorting ( Figure 8-11 To improve neatness, the sorting cylinder 643 is equipped with a through groove 6431 and a clamping arm assembly 6432. The clamping drive mechanism 6433 drives the clamping arms to rotate around the hinge point. Through the cross comb tooth structure, the upper and lower ends of the strip material are brought close together. Under the vibration of the vibrator 648, the strip material can be straightened and arranged as vertically and neatly as possible.

[0037] S5. Final discharge: The sorted materials enter the packaging bag through qualified channel 62, completing the quantitative and neat discharge process.
