Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea packaging machinery, specifically to a rejection mechanism for tea packaging. Background Technology
[0002] In the tea packaging industry, ensuring the accuracy and consistency of tea packaging weight is crucial, as it not only affects the product's quality and image but also directly impacts the company's production efficiency and cost control. To achieve this goal, a tea packaging weighing device has been developed, integrating core components such as an electronic scale, a feeding mechanism, a discharge conveyor belt, and a discharge hopper, forming a relatively complete tea feeding and sorting system.
[0003] Specifically, the electronic scale, as the core component for weight detection, can detect the weight of the tea leaves being fed into the machine and determine whether it meets the preset packaging standards. The feeding mechanism, based on the feedback from the electronic scale, feeds the qualified tea leaves (i.e., "good products") to the discharge conveyor belt, or feeds the unqualified tea leaves (i.e., "defective products") to the discharge hopper. The discharge conveyor belt is responsible for transporting the good tea leaves to the subsequent packaging process, while the discharge hopper serves as a recycling channel for defective products, guiding them back upstream of the feeding conveyor belt for re-weighing and redistribution.
[0004] However, although existing tea packaging weighing devices are functionally quite complete, some inconveniences still exist in actual operation. Firstly, after the tea has passed the weighing test, the good quality tea cannot be directly fed into the tea bags by the feeding mechanism; instead, it requires an additional conveyor belt to complete the unloading process. This process not only increases the complexity and time cost of operation but also results in a larger space requirement for the entire device, which is not conducive to a compact layout and efficient operation of the production line. Secondly, the feeding mechanism feeds the tea horizontally along the weighing surface of the electronic scale, causing tea residue to easily remain on the scale, affecting the accuracy of the tea packaging weight.
[0005] In view of the above problems, it is necessary to develop a rejection mechanism for tea packaging. This mechanism aims to achieve direct and efficient feeding of tea, reduce the overall space occupied, effectively avoid the problem of tea residue during the feeding process, and ensure the accuracy and consistency of tea packaging weight. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] This invention provides a rejection mechanism for tea packaging, which can at least solve the technical problem of how to achieve direct and efficient feeding of tea leaves while reducing the overall space occupied.
[0008] (II) Technical Solution
[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rejection mechanism for tea packaging, comprising:
[0010] Hollow receiving cylinder;
[0011] The first baffle and the second baffle are respectively rotatably mounted on both sides of the receiving cylinder;
[0012] A drive mechanism is located outside the receiving cylinder and is connected to the first baffle and the second baffle in a transmission manner, used to drive the first baffle and the second baffle to rotate toward or away from the first direction;
[0013] When good products are unloaded, the drive mechanism drives the first baffle and the second baffle to rotate in the first direction, and a good product discharge channel communicating with the receiving cylinder is formed between the first baffle, the second baffle and the receiving cylinder; when defective products are unloaded, the drive mechanism drives the first baffle and the second baffle to rotate away from the first direction, and a defective product discharge channel communicating with the receiving cylinder is formed between the first baffle, the second baffle and the receiving cylinder. The good product discharge channel and the defective product discharge channel are respectively inclined downward in two opposite directions.
[0014] Further, the bottom of the aforementioned receiving cylinder is provided with a first inclined surface and a second inclined surface on both sides respectively. The first inclined surface and the second inclined surface are connected on opposite sides, and the other side is inclined upward towards the first baffle and the second baffle respectively. Good product outlet and defective product outlet are respectively formed on the first inclined surface and the second inclined surface.
[0015] When good products are being fed, the first baffle opens the outlet for good products, and the second baffle contacts the second inclined surface and covers the outlet for defective products; when defective products are being fed, the second baffle opens the outlet for defective products, and the first baffle contacts the first inclined surface and covers the outlet for good products.
[0016] Further configuration: the aforementioned receiving cylinder includes two symmetrically arranged first side plates and two symmetrically arranged second side plates. The upper two sides of the first side plates are integrally connected to one side of each of the two second side plates. The lower part of the first side plates is arranged in an inverted triangular shape. The lower parts of the two first side plates and the two second side plates together form a good product outlet and a defective product outlet. The first baffle and the second baffle correspond one-to-one with the two second side plates and are rotatably arranged on the outside of the corresponding second side plates.
[0017] Furthermore, the area of the first baffle is greater than the area of the first inclined surface, and the area of the second baffle is greater than the area of the second inclined surface.
[0018] Specifically, when good products are being fed, the second baffle completely covers the second inclined surface and extends beyond the second inclined surface; when defective products are being fed, the first baffle completely covers the first inclined surface and extends beyond the first inclined surface.
[0019] Furthermore, the aforementioned rejection mechanism for tea packaging also includes a guide plate fixed on the receiving cylinder. The guide plate is located below the good product discharge channel or the defective product discharge channel and extends downwards and outwards from the receiving cylinder.
[0020] In a further embodiment, the aforementioned rejection mechanism for tea packaging also includes a receiving funnel, which is inserted at the top of the receiving cylinder and connected to the receiving cylinder. The receiving funnel is used to supply tea to the receiving cylinder.
[0021] In a further configuration, the aforementioned driving mechanism includes a baffle driving component, which is located on the outside of the receiving cylinder, and the output end of the baffle driving component is connected to the first baffle and the second baffle.
[0022] In a further configuration, the aforementioned driving mechanism includes two baffle driving components, which are located on the outside of the receiving cylinder. The output end of one baffle driving component is connected to the first baffle, and the output end of the other baffle driving component is connected to the second baffle.
[0023] (III) Beneficial Effects
[0024] Compared with the prior art, the rejection mechanism for tea packaging provided by this utility model has the following beneficial effects:
[0025] 1. This rejection mechanism for tea packaging has two modes: defective product feeding and good product feeding. In use, a certain weight of tea to be packaged is poured into the receiving cylinder. If the weight of the tea is within a preset weight range, the good product feeding mode is activated. The drive mechanism rotates the first and second baffles in the first direction, forming a good product discharge channel. The tea in the receiving cylinder is guided to move directly downwards through this channel and then directly into the tea bag for packaging. If the weight of the tea exceeds the preset weight range (too light or too heavy), the defective product feeding mode is activated. The drive mechanism rotates the first and second baffles away from the first direction, forming a defective product discharge channel. The tea in the receiving cylinder is guided to move directly downwards through this channel and then can be moved to a defective product container or returned to the upstream process for reweighting. As can be seen, compared with the existing technology, this utility model can directly guide the tea leaves entering the receiving cylinder into the good product discharge channel or the defective product discharge channel without the need for an additional conveying process, thereby achieving direct and efficient feeding of tea leaves and effectively reducing the overall space occupied.
[0026] 2. The rejection mechanism for tea packaging forms a downward-sloping discharge channel for good or bad products by combining a first baffle, a second baffle, and a receiving cylinder. This not only guides the direction of tea feeding but also slows down the falling speed of the tea, effectively preventing tea from splashing out and affecting the accuracy and consistency of the tea packaging weight.

[0035] 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.
[0036] This invention provides a rejection mechanism for tea packaging, which solves the problem of how to achieve direct and efficient tea feeding while reducing the overall space occupied.
[0037] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a perspective view of the rejection mechanism used for tea packaging in the embodiment. Figure 2 This is a cross-sectional view of the rejection mechanism for tea packaging in the embodiment, showing the defective product unloading state. Figure 3 The image shows a cross-sectional view of the rejection mechanism for tea packaging in the good product feeding state. The rejection mechanism for tea packaging includes a receiving cylinder 1, a first baffle 2, a second baffle 3, and a driving mechanism 4.
[0038] The first baffle 2 and the second baffle 3 are rotatably connected to both sides of the receiving cylinder 1.
[0039] The drive mechanism 4 is installed outside the receiving cylinder 1 by welding or screwing, and is connected to the first baffle 2 and the second baffle 3 in a transmission manner. The drive mechanism 4 is used to drive the first baffle 2 and the second baffle 3 to rotate toward or away from the first direction.
[0040] When good products are unloaded, the drive mechanism 4 drives the first baffle 2 and the second baffle 3 to rotate in the first direction, forming a good product discharge channel 5 connected to the receiving cylinder 1. When defective products are unloaded, the drive mechanism 4 drives the first baffle 2 and the second baffle 3 to rotate away from the first direction, forming a defective product discharge channel 6 connected to the receiving cylinder 1. The good product discharge channel 5 and the defective product discharge channel 6 extend downwards at an angle in two opposite directions.
[0041] The above technical solution for the tea packaging rejection mechanism has two modes: defective product feeding and good product feeding. In use, a certain weight of tea to be packaged is poured into the receiving cylinder 1. If the weight of the tea is within a preset weight range, the good product feeding mode is activated. The drive mechanism 4 drives the first baffle 2 and the second baffle 3 to rotate in the first direction, forming a good product discharge channel 5. The tea in the receiving cylinder 1 is guided to move directly downwards through the good product discharge channel 5 and exit the receiving cylinder 1, thus directly entering the tea bag for packaging. If the weight of the tea exceeds the preset weight range (the tea is too light or too heavy), the defective product feeding mode is activated. The drive mechanism 4 drives the first baffle 2 and the second baffle 3 to rotate away from the first direction, forming a defective product discharge channel 6. The tea in the receiving cylinder 1 is guided to move directly downwards through the defective product discharge channel 6 and exit the receiving cylinder 1, thus moving to the defective product container or flowing back to the upstream process for reweighting. As can be seen, compared with the prior art, this utility model can directly guide the tea leaves entering the receiving cylinder 1 into the good product discharge channel 5 or the defective product discharge channel 6 without an additional conveying process, achieving direct and efficient tea leaf discharge and effectively reducing the overall space occupied. Furthermore, the rejection mechanism for tea packaging, through the combination of the first baffle 2, the second baffle 3, and the receiving cylinder 1, forms an inclined downward-extending good product discharge channel 5 or defective product discharge channel 6, which not only guides the direction of tea leaf discharge but also slows down the falling speed of the tea leaves, effectively preventing tea leaves from splashing out and affecting the accuracy and consistency of the tea packaging weight.
[0042] The rejection mechanism for tea packaging described above should also include a weight sieving device (not shown in the figure). The weight sieving device is installed inside or above the receiving cylinder 1 to detect whether the weight of the tea is within a preset range, and to sieve good and bad products based on the detection results. If the detected weight value is within the preset range, the good product feeding mode is activated; if the detected weight value exceeds the preset range, the bad product feeding mode is activated, thereby separating good and bad products and classifying the feeding to prevent the packaged tea from not meeting the specified weight. This weight sieving device can be formed by combining an existing weighing device and controller to switch between the good product feeding mode and the bad product feeding mode based on the weighing results.
[0043] See Figure 2 and Figure 3 As shown, in one embodiment of the receiving cylinder 1, a first inclined surface 11 and a second inclined surface 12 are respectively provided on both sides of the bottom of the receiving cylinder 1. The first inclined surface 11 and the second inclined surface 12 are connected on opposite sides, the other side of the first inclined surface 11 extends upward towards the first baffle 2, and the other side of the second inclined surface 12 extends upward towards the second baffle 3. A good product outlet 111 and a defective product outlet 121 are respectively formed on the first inclined surface 11 and the second inclined surface 12. When good products are discharged, the first baffle 2 opens the good product outlet 111, and the second baffle 3 contacts the second inclined surface 12 and covers the defective product outlet 121; when defective products are discharged, the second baffle 3 opens the defective product outlet 121, and the first baffle 2 contacts the first inclined surface 11 and covers the good product outlet 111. Thus, when good tea is discharged, the second baffle 3 contacts the second inclined surface 12, completely sealing the defective product outlet 121. It also slows the falling speed of the tea leaves in the receiving cylinder 1 and guides the tea leaves to tilt downwards towards the good product outlet 111, effectively preventing tea residue or leakage from the receiving cylinder 1 into the defective product storage area, thus avoiding an excessively light tea packaging weight. Conversely, when defective tea is discharged, the first baffle 2 contacts the first inclined surface 11, completely sealing the good product outlet 111. It also slows the falling speed of the tea leaves in the receiving cylinder 1 and guides the tea leaves to tilt downwards towards the defective product outlet 121, effectively preventing tea residue or leakage from the receiving cylinder 1 into the good product storage area, where it mixes with the next batch of qualified tea in the same tea bag, resulting in an excessively heavy tea packaging weight. In summary, the rejection mechanism provided in this embodiment effectively prevents tea residue or leakage, thereby ensuring the accuracy and consistency of the tea packaging weight.
[0044] See Figure 1 , Figure 2 and Figure 3As shown, based on the above embodiment, the receiving cylinder 1 includes two symmetrically arranged first side plates 13 and two symmetrically arranged second side plates 14. The upper two sides of the first side plates 13 are integrally connected to one side of each of the two second side plates 14. The lower part of the first side plates 13 is arranged in an inverted triangular shape. The lower parts of the two first side plates 13 and the two second side plates 14 enclose each other to form a good product outlet 111 and a defective product outlet 121. The first baffle 2 and the second baffle 3 correspond one-to-one with the two second side plates 14 and are rotatably connected to the outside of the corresponding second side plates 14. It can be seen that the receiving cylinder 1 forms a hollow square cylinder structure by the enclosed space of the two first side plates 13 and the second side plates 14. The lower part of the first side plate 13 is inverted triangular in shape to form a first inclined surface 11 with a good product outlet 111 and a second inclined surface 12 with a defective product outlet 121. The receiving cylinder 1 has a simple structure and is easy to manufacture.
[0045] See Figure 2 and Figure 3 As shown, based on any of the above embodiments, the area of the first baffle 2 is larger than the area of the first inclined surface 11, and the area of the second baffle 3 is larger than the area of the second inclined surface 12. Specifically, when good products are being fed, the second baffle 3 completely covers the second inclined surface 12 and extends beyond it; when defective products are being fed, the first baffle 2 completely covers the first inclined surface 11 and extends beyond it. Thus, the first baffle 2 and the second baffle 3 not only ensure complete sealing of the good product outlet 111 and the defective product outlet 121 respectively, but also extend the guiding stroke for the tea leaves, further preventing tea residue or leakage, thereby further ensuring the accuracy and consistency of the tea packaging weight.
[0046] See Figure 1 , Figure 2 and Figure 3 As shown, based on any of the above embodiments, the rejection mechanism for tea packaging also includes a guide plate 7. The guide plate 7 is fixed to the receiving cylinder 1 by welding, screwing, or integral connection. The guide plate 7 is located below the good product discharge channel 5 or the defective product discharge channel 6, and extends downwards and outwards from the receiving cylinder 1. In this way, the guide plate 7 can increase the distance between the good product discharge position and the defective product discharge position, effectively avoiding the situation where the good and defective product discharge positions are too close and mixed. In addition, the guide plate 7 can also facilitate bagging and receiving of materials.
[0047] See Figure 1 , Figure 2 and Figure 3As shown, based on any of the above embodiments, the rejection mechanism for tea packaging further includes a receiving funnel 8. The receiving funnel 8 is inserted into the top of the receiving cylinder 1 and communicates with the receiving cylinder 1. The receiving funnel 8 is used to supply tea to the receiving cylinder 1. In this way, the receiving funnel 8 can enlarge the opening at the top of the receiving cylinder 1, making it easier to accurately guide the tea into the receiving cylinder 1.
[0048] See Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of the drive mechanism 4, the drive mechanism 4 includes two baffle drive members 41. The baffle drive members 41 are disposed on the outside of the receiving cylinder 1 by means of welding or screwing. The output end of one baffle drive member 41 is connected to the first baffle 2 by means of welding or screwing, and the output end of the other baffle drive member 41 is connected to the second baffle 3 by means of welding or screwing. Thus, when good products are unloaded, the two baffle drive members 41 respectively drive the first baffle 2 and the second baffle 3 to rotate in the first direction, causing the first baffle 2 to flip outward from the receiving cylinder 1 and open the good product outlet 111, while the second baffle 3 contacts the second inclined surface 12 and covers the defective product outlet 121, thereby forming the good product outlet channel 5. When defective products are unloaded, the two baffle drive members 41 respectively drive the first baffle 2 and the second baffle 3 to rotate away from the first direction, causing the second baffle 3 to flip outward from the receiving cylinder 1 and open the defective product outlet 121, while the first baffle 2 contacts the first inclined surface 11 and covers the good product outlet 111, thereby forming the defective product outlet channel 6. It can be seen that the two baffle drive members 41 can independently control the flipping stroke of the first baffle 2 and the second baffle 3 without interfering with each other, so that the extreme positions of the flipping stroke of the first baffle 2 and the second baffle 3 can be adjusted separately.
[0049] Both of the aforementioned baffle drive components 41 can use existing servo motors, stepper motors, or rotary cylinders, etc., to facilitate precise control of the tilting stroke of the first baffle 2 and the second baffle 3.
[0050] In another embodiment of the drive mechanism 4, the drive mechanism 4 includes a baffle drive member 41. The baffle drive member 41 is disposed on the outside of the receiving cylinder 1 by means of welding or screwing, and the output end of the baffle drive member 41 is connected to the first baffle 2 and the second baffle 3 by means of welding or screwing. In this way, the drive mechanism 4 can simultaneously control the synchronous flipping movement of the first baffle 2 and the second baffle 3 through a single baffle drive member 41, which greatly saves drive costs.
[0051] The aforementioned baffle drive 41 can use existing servo motors, stepper motors, or rotary cylinders, etc., as rotary drive mechanisms 4, and is connected to the first baffle 2 and the second baffle 3 via a transmission mechanism such as a gear set, so as to simultaneously control the flipping motion of the first baffle 2 and the second baffle 3.
[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
