Description

Technical Field

[0001] This utility model relates to the field of packaging mechanism technology, and more specifically, to an automatic inner and outer packaging mechanism for nylon triangular bags. Background Technology

[0002] In today's product packaging industry, nylon triangular bags, as a unique packaging form, are widely used for packaging various products such as tea, coffee, and condiments due to their excellent flexibility, moisture resistance, and aesthetic appeal. However, with the continuous growth of market demand and the increasing requirements of consumers for product packaging quality and efficiency, traditional nylon triangular bag packaging methods are facing many challenges. Currently, when packaging tea using nylon triangular bag inner and outer packaging machines, the tea raw materials are generally poured into the feed hopper and discharged into the packaging bag through a guide tube. After packaging one tea bag, the device pauses, and the feeding component transports the packaging bag downwards. However, there is no limiting device on the guide tube, so the feeding cannot be stopped in time. As the packaging bag is transported downwards, residual raw materials fall out, affecting the normal packaging process.

[0003] To address the aforementioned issues, particularly the lack of a limiting device on the feed tube of existing nylon triangular bag packaging machines, which prevents timely stopping of feeding and causes residual material to fall out during downward transport of the bags, thus affecting normal packaging, extensive research revealed a patent publication number CN210882847U for an automatic inner and outer packaging mechanism for nylon triangular bags. This device, belonging to the tea bag packaging technology field, uses an electric push rod to control a baffle to move forward during packaging, allowing the material to be discharged from the feed outlet of the guide frame and the baffle into the bag. This guides the material flow, preventing excessive material from falling out at once. After packaging one triangular bag, the electric push rod pulls the baffle back, blocking the material inside the guide frame and preventing further downward fall during packaging pauses.

[0004] However, the aforementioned automatic inner and outer packaging mechanism for nylon triangular bags still has some problems. For example, when there is too much raw material in the storage box and discharge hopper, the movement of the baffle pushed by the electric push rod is hindered, which can easily cause the baffle to fail to reset, affecting the normal use of the device. To address these problems, this utility model proposes an automatic inner and outer packaging mechanism for nylon triangular bags. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide an automatic inner and outer packaging mechanism for nylon triangular bags.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic inner and outer packaging mechanism for nylon triangular bags, comprising a packaging machine body, a controller, a conveying system, a sealing system, and an outer packaging system, a fixed cylinder, which is a hollow structure with a feed hopper and a discharge hopper respectively connected to its upper and lower ends, a feed hopper and a discharge port that are connected to the feed hopper and discharge hopper respectively through the fixed cylinder, the discharge hopper being fixedly installed on the packaging machine body, the bottom of the discharge hopper being connected to the conveying system via a discharge pipe, and a first rotating shaft being rotatably connected inside the fixed cylinder, the first rotating shaft being circumferentially connected to the fixed cylinder. Multiple partitions are fixedly connected along the longitudinal direction, dividing the inside of the fixed cylinder into multiple cavities. An mounting plate is fixedly connected to the main body of the packaging machine. The mounting plate is provided with a grooved wheel mechanism that drives the first rotating shaft to rotate intermittently. The grooved wheel mechanism includes a drive plate, which is rotatably mounted on the mounting plate via a second rotating shaft driven by a motor. A drive rod and a driven disc are vertically fixedly connected to the drive plate and are sleeved and fixedly connected to the first rotating shaft. The driven disc has a drive groove of equal size to the cavity, and the drive rod can abut against the drive groove.

[0007] A further preferred embodiment: a turntable is sleeved and fixedly connected to the second rotating shaft, the driven disk is arranged parallel to the turntable, and the driven disk has a positioning groove of the same amount as the driving groove. The positioning groove is an arc-shaped structure and is coaxial with the turntable.

[0008] A further preferred embodiment: the diameter of the driven disk is equal to the diameter of the turntable.

[0009] A further preferred embodiment: the drive slot is located between adjacent positioning slots.

[0010] A further preferred embodiment: the first rotating shaft passes through and is rotatably mounted on the mounting plate, an auxiliary disk is sleeved on the first rotating shaft, and the auxiliary disk is provided with an arc-shaped groove and an auxiliary groove that respectively match the positioning groove and the driving groove.

[0011] A further preferred embodiment: a sealing gasket is fixedly connected to one end of each of the multiple partitions that contacts the inner wall of the fixed cylinder.

[0012] Beneficial effects:

[0013] 1. By incorporating a Geneva wheel mechanism, partitions, and a first rotating shaft, the Geneva wheel mechanism controls the intermittent rotation of the first rotating shaft, allowing multiple cavities to be intermittently connected to the inlet and outlet. The overall structure is simple to operate and highly automated. The Geneva wheel mechanism enables the intermittent rotation of the first rotating shaft, thereby accurately controlling the quantitative separation and conveying of materials. This avoids the problem of inaccurate measurement caused by a large amount of material flowing out at once, improves the accuracy of material measurement during the packaging process, helps ensure the consistency of product quantity in each nylon triangular bag, and enhances product quality and packaging standardization.

[0014] 2. By setting up positioning grooves, turntables, and auxiliary discs, the intermittency and stability of the first rotating shaft are further ensured through the cooperation of the positioning grooves, auxiliary discs, and turntables. This prevents the first rotating shaft from rotating unnecessarily due to external forces or inertia in the non-drive state, improves the reliability and accuracy of the entire metering and conveying system, reduces metering errors caused by equipment failure or instability, and helps to improve the continuity of packaging production and the stability of product quality.

[0015] 3. By incorporating a sealing gasket, the sealing performance of the internal cavity of the fixed cylinder is improved, ensuring the independence and integrity of the material in each cavity, avoiding cross-contamination and measurement errors, further enhancing the accuracy of material measurement, ensuring the precision of the product quantity in each nylon triangular bag, and also helping to maintain a clean working environment, reducing material waste and cleaning work.

Detailed Implementation

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-5 In this embodiment of the present invention, an automatic inner and outer packaging mechanism for nylon triangular bags includes a packaging machine body 1, a controller 5, a conveying system 2, a sealing system 3, and an outer packaging system 4. A fixed cylinder 10 is hollow and has a feed hopper 6 and a discharge hopper 13 connected to its upper and lower ends, respectively. The fixed cylinder 10 has a feed hopper 6 and a discharge port 15 that are connected to the feed hopper 6 and discharge hopper 13 respectively. The discharge hopper 13 is fixedly installed on the packaging machine body 1. The bottom of the discharge hopper 13 is connected to the conveying system 2 via a discharge pipe 7. A first rotating shaft 11 is rotatably connected inside the fixed cylinder 10, and the first rotating shaft 11 is fixedly connected along its circumference. There are multiple partitions 8, which divide the inside of the fixed cylinder 10 into multiple cavities 22. A mounting plate 12 is fixedly connected to the packaging machine body 1. The mounting plate 12 is provided with a grooved wheel mechanism 9 that drives the first rotating shaft 11 to rotate intermittently. The grooved wheel mechanism 9 includes a drive plate 92, which is rotatably mounted on the mounting plate 12 via a second rotating shaft 94. The second rotating shaft 94 is driven by a motor 91. A drive rod 93 and a driven disc 95 are vertically fixedly connected to the drive plate 92. The driven disc 95 is sleeved and fixedly connected to the first rotating shaft 11. A drive groove 96 with the same amount as the cavity 22 is opened on the driven disc 95. The drive rod 93 can abut against the drive groove 96.

[0024] Specifically, the motor 91 is fixedly mounted on the mounting plate 12. Empty nylon triangular bags are conveyed to the bottom of the discharge pipe 7 via the conveying system 2. At this time, material enters the fixed cylinder 10 from the feed hopper 6. Since the partition 8 on the first rotating shaft 11 divides the fixed cylinder 10 into multiple cavities 22, when the motor 91 drives the second rotating shaft 94 to rotate, it drives the drive plate 92 to rotate. The drive rod 93 on the drive plate 92 rotates accordingly. When the drive rod 93 enters the drive groove 96 of the driven disc 95, it pushes the driven disc 95 to rotate at a certain angle, thereby driving the first rotating shaft 11 to rotate. The rotation of the first rotating shaft 11 changes the position of one of the cavities 22 connected to the feed inlet 14 and the discharge outlet 15, achieving intermittent quantitative feeding of the material. The material is separated and conveyed. When the material in the cavity 22 rotates to the discharge port 15 as the first rotating shaft 11 rotates, it falls onto the conveying system 2 through the discharge pipe 7 at the bottom of the discharge hopper 13 for subsequent packaging. Then, the triangular bags filled with the product are sequentially conveyed to the sealing system 3 and the outer packaging system 4, and finally conveyed out along the packaging machine body 1. The overall structure is simple to operate and highly automated. The intermittent rotation of the first rotating shaft 11 is achieved through the groove wheel mechanism 9, which can accurately control the quantitative separation and conveying of the material, avoid the problem of inaccurate measurement caused by a large amount of material flowing out at once, improve the accuracy of material measurement during the packaging process, help ensure the consistency of the product quantity in each nylon triangular bag, and improve product quality and packaging standardization.

[0025] It should be noted that in this embodiment, the structure, installation, and operation of the packaging machine body 1, controller 5, conveying system 2, sealing system 3, and outer packaging system 4 are all existing technologies. The conveying system 2 typically includes a conveyor belt and a transmission device. The conveyor belt is generally made of wear-resistant rubber or plastic and is used to transport nylon triangular bags from one working area to another. The transmission device typically consists of a motor 91, a reducer, and a roller. The motor 91 provides power, and the speed is adjusted by the reducer to drive the roller to rotate, thereby making the conveyor belt run. The sealing system 3 typically consists of a heat sealing device or an ultrasonic sealing device. The outer packaging system 4 can be a carton forming machine, a wrapping machine, etc. The carton forming machine can fold flat carton material into a box shape and put the nylon triangular bags containing the product into the box. The wrapping machine uses plastic film to wrap multiple nylon triangular bags or cartons containing triangular bags, which serves to prevent moisture and dust. The controller 5 typically consists of a PLC (Programmable Logic Controller 5) and sensors.

[0026] In this embodiment of the utility model, such as Figure 3 , Figure 4 and Figure 5As shown, a turntable 17 is sleeved and fixedly connected to the second rotating shaft 94. A driven disk 95 is arranged parallel to the turntable 17. The driven disk 95 has a positioning groove 18 of equal size to the driving groove 96. The positioning groove 18 has an arc-shaped structure and is coaxial with the turntable 17. The diameter of the driven disk 95 is equal to the diameter of the turntable 17. The driving groove 96 is located between adjacent positioning grooves 18. Specifically, the rotation of the second rotating shaft 94 drives the turntable 17 to rotate. When the driving rod 93 disengages from the driving groove 96 of the driven disk 95, the turntable 17 interacts with the positioning groove 18. Because the positioning groove 18 has an arc-shaped structure and is coaxial with the turntable 17, the turntable 17 rotates... During the process, the driven disc 95 can enter the positioning groove 18, thereby restricting the rotation of the driven disc 95 and keeping the first rotating shaft 11 stationary until the drive rod 93 enters the next drive groove 96 again. This achieves precise positioning and intermittent control of the rotation of the driven disc 95. The cooperation between the positioning groove 18 and the turntable 17 further ensures the intermittency and stability of the rotation of the first rotating shaft 11, preventing unnecessary rotation of the first rotating shaft 11 due to external force or inertia in the non-drive state. This improves the reliability and accuracy of the entire metering and conveying system 2, reduces metering errors caused by equipment failure or instability, and helps to improve the continuity of packaging production and the stability of product quality.

[0027] In this embodiment of the utility model, such as Figure 5 As shown, a first rotating shaft 11 is rotatably mounted on a mounting plate 12. An auxiliary disk 19 is sleeved on the first rotating shaft 11. The auxiliary disk 19 has arc-shaped grooves 21 and auxiliary grooves 20 that respectively match the positioning groove 18 and the drive groove 96. Specifically, the first rotating shaft 11 passes through the mounting plate 12 and the auxiliary disk 19 is sleeved on it. When the first rotating shaft 11 rotates, the auxiliary disk 19 rotates accordingly. The arc-shaped grooves 21 and auxiliary grooves 20 on the auxiliary disk 19 match the positioning groove 18 and the drive groove 96 respectively. During the process of the turntable 17 cooperating with the positioning groove 18 and the drive rod 93 cooperating with the drive groove 96, the auxiliary disk 19 plays a role in assisting positioning and guiding movement, further enhancing the stability and accuracy of the entire transmission system.

[0028] In this embodiment of the utility model, such as Figure 2 As shown, sealing gaskets 16 are fixedly connected to the ends of the multiple partitions 8 that contact the inner wall of the fixed cylinder 10. Specifically, the sealing gaskets 16 improve the sealing performance of the internal cavity 22 of the fixed cylinder 10, ensuring the independence and integrity of the material in each cavity 22, avoiding cross-contamination and measurement errors, further improving the accuracy of material measurement, ensuring the precision of the product quantity in each nylon triangular bag, and also helping to maintain a clean working environment, reducing material waste and cleaning work.

[0029] Working principle: Empty nylon triangular bags are conveyed to the bottom of the discharge pipe 7 via the conveying system 2. At this time, the material enters the fixed cylinder 10 from the feed hopper 6. Since the partition 8 on the first rotating shaft 11 divides the fixed cylinder 10 into multiple cavities 22, when the motor 91 drives the second rotating shaft 94 to rotate, it drives the drive plate 92 to rotate. The drive rod 93 on the drive plate 92 rotates accordingly. When the drive rod 93 enters the drive groove 96 of the driven plate 95, it pushes the driven plate 95 to rotate at a certain angle, which in turn drives the first rotating shaft 11 to rotate. The rotation of the first rotating shaft 11 changes the position of one of the cavities 22 connected to the feed port 14 and the discharge port 15, realizing the intermittent quantitative separation and conveying of the material. When the material separated in the cavity 22 reaches the discharge port 15 position as the first rotating shaft 11 rotates, it falls onto the conveying system 2 through the discharge pipe 7 at the bottom of the discharge hopper 13 for subsequent packaging. At the same time, the rotation of the second rotating shaft 94 drives the turntable 17 to rotate. After the moving rod 93 disengages from the drive groove 96 of the driven disc 95, the turntable 17 interacts with the positioning groove 18. Since the positioning groove 18 is an arc-shaped structure and is coaxially set with the turntable 17, the turntable 17 can enter the positioning groove 18 during rotation, thereby restricting the rotation of the driven disc 95 and keeping the first rotating shaft 11 stationary until the driving rod 93 enters the next drive groove 96 again. This achieves precise positioning and intermittent control of the rotation of the driven disc 95. Finally, the triangular bags filled with the product are sequentially conveyed to the sealing system 3 and the outer packaging system 4, and then conveyed out along the packaging machine body 1. The overall structure is simple to operate and highly automated. The intermittent rotation of the first rotating shaft 11 is achieved through the groove wheel mechanism 9, which can accurately control the quantitative separation and conveying of materials, avoid the problem of inaccurate measurement caused by a large amount of material flowing out at once, improve the accuracy of material measurement during the packaging process, help ensure the consistency of the product quantity in each nylon triangular bag, and improve product quality and packaging standardization.
