Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a packaging device for resin granules. Background Technology

[0002] In the packaging of resin granules, a screw conveyor inside a transfer tube transports the granules. The rotating screw generates a driving force that allows the granules to move stably and orderly along the transfer tube. An electronic scale is installed below the packaging bag. Before conveying the granules into the bag, the predetermined weight (in kilograms) is set based on the requirements of subsequent production and sales stages regarding granule usage and packaging specifications. During this process, the electronic scale monitors the weight changes of the granules in the bag in real time, stopping conveying when the specified weight is reached. The electronic scale controls the amount of granules added, ensuring that each bag meets the predetermined weight standard. The packaging bag is then removed for repackaging. In existing technologies, only one screw conveyor is typically used for transporting resin granules. However, in actual granule transport, inaccurate control of the conveying volume can easily occur, potentially leading to excessive granules being introduced into the packaging bag. This makes it difficult to strictly adhere to the pre-set weight standard, negatively impacting the standardization of subsequent granule packaging and the overall orderliness of the production process.

[0027] Example 1

[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a packaging device for resin granules. The packaging device for resin granules includes a main component 100 and a conveying component 200. The two work together to precisely control the conveying volume, avoid overfilling, and ensure that the filling standards and processes are standardized and orderly.

[0029] The main component 100 includes a transmission box 101, a mounting bracket 102 is provided below the transmission box 101, and an electronic scale 103 is provided below the mounting bracket 102.

[0030] A feed inlet is provided at the top of the transfer box 101. The resin to be transported is poured into the transfer box 101 through the feed inlet, and then transported by the transfer box 101 to the packaging bag. The packaging bag can be fixed on the mounting frame 102. The resin particles transported in the packaging bag can be weighed by the electronic scale 103. Both the transfer box 101 and the mounting frame 102 are fixed on the outer fixed frame. The installation of the transfer box 101 and the mounting frame 102 is prior art and common knowledge to those skilled in the art, so it will not be described in detail.

[0031] The conveying assembly 200 is disposed on the transfer box 101 and includes a conveying component 201. The conveying component 201 includes a conveying pipe 2011, which is fixed to one side of the transfer box 101. A spiral rod 2012 is disposed inside the conveying pipe 2011, and a sealing door 2013 is hinged inside the conveying pipe 2011. A connecting pipe 2014 is disposed inside the transfer box 101.

[0032] Two sets of conveying components 201 are installed on the transfer box 101. The two conveying pipes 2011 and the screw rod 2012 are of different sizes. The connecting pipe 2014 is connected to the two conveying pipes 2011. When resin particles are added, they are conveyed to the two conveying pipes 2011 through the connecting pipe 2014. First, the closing door 2013 on one side of the large screw rod 2012 is opened, and then the large screw rod 2012 can rotate to convey the resin particles. When the amount of resin particles conveyed in the packaging bag is close to the threshold, the closing door 2013 on one side of the large screw rod 2012 is closed, and the large screw rod 2012 stops rotating, sealing the large conveying pipe 2011. Then the closing door 2013 on one side of the small screw rod 2012 is opened, and then the small screw rod 2012 can rotate to convey the resin particles, thus conveying less resin and making it easier to control the threshold.

[0033] Example 2

[0034] Reference Figures 2-5This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the conveying assembly 200 also includes a moving part 202, which includes a turntable 2021. The turntable 2021 is fixed to the top of the closed door 2013, and a cylinder 2022 is hinged to one side of the turntable 2021.

[0036] There are two sets of moving parts 202, both of which are installed on the closed door 2013. The turntable 2021 is rotatably connected to the transmission box 101 via a rotating shaft. The turntable 2021 is fixed to the top of the closed door 2013. There are two cylinders 2022, both of which are fixed to one side of the transmission box 101. When the closed door 2013 needs to be moved, the cylinders 2022 are activated. At this time, the cylinders 2022 can drive the turntable 2021 to rotate. The rotation of the turntable 2021 can drive the closed door 2013 to move. When the closed door 2013 is opened, the screw rod 2012 can rotate. When the closed door 2013 is closed, the screw rod 2012 will stop.

[0037] Specifically, a hinge rod 2023 is provided on the top of the turntable 2021. The hinge rod 2023 is hinged to the top of the turntable 2021, and a drive frame 2024 is hinged to one end of the hinge rod 2023.

[0038] When the turntable 2021 rotates, it can drive the hinge rod 2023 to move. At this time, the movement of the hinge rod 2023 can drive the drive frame 2024 to move. The movement of the drive frame 2024 can stop the rotation of the screw rod 2012.

[0039] Specifically, a first rotating rod 2025 is fixed to one side of the screw rod 2012, and a second rotating rod 2026 is fixed to one side of the first rotating rod 2025.

[0040] Rotating the second rotating rod 2026 can drive the first rotating rod 2025 to rotate. The first rotating rod 2025 is inserted into one side of the transmission box 101. The first rotating rod 2025 is rotatably connected to one side of the transmission box 101 through a rotating shaft. Rotating the first rotating rod 2025 can drive the screw rod 2012 to rotate.

[0041] Specifically, a rotating sleeve 2027 is fitted on the outer side of the first rotating rod 2025, and the rotating sleeve 2027 and the first rotating rod 2025 are movably connected.

[0042] The first rotating rod 2025 and the second rotating rod 2026 are both inserted into the rotating sleeve 2027 and are movably connected to the rotating sleeve 2027. A retaining strip is fixed on one side of the second rotating rod 2026, and a retaining groove corresponding to the retaining strip is opened on one side of the rotating sleeve 2027. A sliding strip is fixed on one side of the first rotating rod 2025, and a sliding groove corresponding to the sliding strip is opened on one side of the rotating sleeve 2027.

[0043] When the closed door 2013 opens the drive frame 2024, it can drive the rotating sleeve 2027 to move. At this time, the slide can slide on the slide bar. Then, the rotating sleeve 2027 can drive the slot to move and engage with the slot bar. Then, the rotation of the second rotating rod 2026 drives the slot bar to rotate and presses the slot bar, causing the rotating sleeve 2027 to rotate. When the rotating sleeve 2027 rotates, it can drive the slide to press the slide bar, causing the first rotating rod 2025 to rotate. The rotation of the first rotating rod 2025 can drive the screw rod 2012 to rotate.

[0044] Specifically, a spring 2028 is fixed on one side of the rotating sleeve 2027, and a drive ring 2029 is sleeved on the outside of the rotating sleeve 2027. The drive ring 2029 and the rotating sleeve 2027 are rotatably connected by a rotating shaft.

[0045] When the rotating sleeve 2027 moves, it can apply a squeezing force to the spring 2028. The spring 2028 rebounds and drives the rotating sleeve 2027 back to its original position. When the drive frame 2024 moves, it can drive the drive ring 2029 to move. The movement of the drive ring 2029 can drive the rotating sleeve 2027 to move.

[0046] Specifically, the conveying assembly 200 also includes a connector 203, which includes a connecting plate 2031, and the connecting plate 2031 is fixed to the top of the drive ring 2029.

[0047] The connecting plate 2031 is fixed to one side of the drive frame 2024. When the drive frame 2024 moves, it can drive the connecting plate 2031 to move. At this time, the movement of the connecting plate 2031 can drive the drive ring 2029 to move.

[0048] Example 3

[0049] Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, a pulley 2032 is fixed to one end of the second rotating rod 2026, and a belt 2033 is installed inside the pulley 2032.

[0051] There are two pulleys 2032, both fixed to one end of the second rotating rod 2026. The rotation of the pulleys 2032 can drive the second rotating rod 2026 to rotate. When the pulleys 2032 rotate, they can drive the belt 2033 to rotate. At this time, the rotation of the belt 2033 can drive the other pulley 2032 to rotate, so that the two pulleys 2032 can rotate at the same time.

[0052] Specifically, a protective cover 2034 is fixed on one side of the transmission box 101. The protective cover 2034 is sleeved on the outside of the connecting plate 2031, and the protective cover 2034 and the connecting plate 2031 are movably connected.

[0053] The protective cover 2034 can protect the pulley 2032, preventing the pulley 2032 and related components from being exposed and damaged by external debris.

[0054] Specifically, a motor 2035 is fixed to one side of the pulley 2032, and a positioning plate 2036 is fixed to the bottom of the motor 2035. The positioning plate 2036 is fixed to one side of the protective cover 2034.

[0055] The motor 2035 is plugged into one side of the protective cover 2034. The motor 2035 and the protective cover 2034 are rotatably connected by a rotating shaft. By starting the motor 2035, the pulley 2032 can be driven to rotate. The positioning plate 2036 can support the motor 2035 and prevent the motor 2035 from shifting.

[0056] In operation, resin particles are first fed into the transfer box 101. These particles are then conveyed to two separate transfer pipes 2011 via the connecting pipe 2014. Next, the closing door 2013 on one side of the large spiral rod 2012 is activated. The starting cylinder 2022 drives the turntable 2021 to rotate, which in turn moves the closing door 2013 to open it. Simultaneously, the rotation of the turntable 2021 moves the hinge rod 2023, which in turn moves the drive frame 2024. The movement of the drive frame 2024 drives the connecting plate 2031 to move, which in turn drives the drive ring 2029 to move. The drive ring 2029 then drives the rotating sleeve 2027 to move, allowing the slide groove to slide on the slide bar. The rotating sleeve 2027 then drives the slot to move and engage with the slide bar. At this point, the motor 2035 is started, driving the pulley 2032 to rotate. The rotation of the pulley 2032 then drives the second rotating rod 2026 to rotate. The rotation of 26 causes the card strip to rotate, pressing against the card slot and causing the rotating sleeve 2027 to rotate. The rotation of the rotating sleeve 2027, in turn, causes the slide groove to press against the slide strip, causing the first rotating rod 2025 to rotate. The rotation of the first rotating rod 2025 then drives the screw rod 2012 to rotate, thus conveying the resin granules. When the resin granules in the bag are close to the threshold, the cylinder 2022 is activated to rotate the turntable 2021, which closes the sealing door 2013 on one side of the large screw rod 2012. The drive frame 2024 can be driven back to its original position, which in turn can cause the rotating sleeve 2027 to return to its original position. At this time, the rotating sleeve 2027 can cause the slot and the strip to separate. When the rotating sleeve 2027 rotates, it will not drive the first rotating rod 2025 to rotate, thus preventing the large spiral rod 2012 from rotating. At this time, the cylinder 2022 on the small spiral rod 2012 is activated, which can open the closed door 2013 on one side of it and make the small spiral rod 2012 rotate to transport the resin particles so as to control the threshold.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
