At the same time, the state of the raw materials is adjusted by heating, stirring and other structural adjustments to provide qualified base materials for subsequent molding processes.
[0003] Patent CN218576685U discloses a packaging bag production device, including a mixing chamber and a drive assembly. A top plate is fixedly installed on the top of the mixing chamber, and a mounting frame is fixedly installed on the top of the top plate. The drive assembly is located above the mounting frame. The drive assembly includes a motor mounting frame, a motor, second pulleys, a conveyor belt, and a drive belt. The bottom of the motor mounting frame is fixed to the top of the mounting frame. The motor is fixedly installed inside the motor mounting frame, with its output end facing downwards. A second stirring shaft is fixedly installed at the output end of the motor, penetrating the upper sidewall of the mounting frame and the top plate. Two second pulleys are fixedly installed above the center of the mounting frame. This packaging bag production device achieves uniform heating and reduces air in the melted virgin polypropylene granules, improving product quality and demonstrating good practicality.
[0004] During use, the aforementioned patent has poor device maintenance and disassembly convenience, and the replacement or maintenance of parts takes a long time. In addition, the first stirring shaft only rotates in a single rotation with the conveyor belt, which may lead to uneven mixing of materials in the corner areas of the mixing chamber. Based on this, a high-strength environmentally friendly packaging bag production device is proposed for improvement. Utility Model Content
[0005] In view of the poor convenience of inspection and disassembly of the existing device, the long time required for component replacement or maintenance, and the problem of uneven material mixing in the corner area of the mixing chamber, this utility model is proposed.
[0006] To solve the above technical problems, this utility model provides the following technical solution: a high-strength environmentally friendly packaging bag production device, including a mixing tank, with symmetrically arranged installation grooves at the top of the mixing tank, a plurality of positioning pins fixedly connected to the top of the mixing tank, a top cover at the top of the mixing tank, a positioning groove adapted to the positioning pins at the bottom of the top cover, a plurality of bolts on the top cover, the bottom ends of the bolts passing through the top of the top cover and threadedly connected to the inside of the positioning pins, and a sealing gasket fixedly connected to the bottom of the top cover, the bottom end of the sealing gasket contacting the top of the mixing tank;
[0007] The top cover includes a power mechanism. A motor is fixedly mounted on the top of the top cover via a mounting bracket. A transmission rod is fixedly sleeved on the output shaft of the motor. The transmission rod is rotatably connected to the inside of the top cover. An installation plate is fitted into the inner wall of the installation groove. Handles are symmetrically provided on the top of the installation plate. A first stirring shaft is rotatably connected to the center of the installation plate.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a high-strength environmentally friendly packaging bag production device, including a mixing tank 1. The top of the mixing tank 1 is symmetrically provided with mounting grooves 12. Several positioning pins 13 are fixedly connected to the top of the mixing tank 1. The top of the mixing tank 1 is provided with a top cover 2. The bottom of the top cover 2 is provided with a positioning groove 21 that is adapted to the positioning pins 13. Several bolts 22 are provided on the top of the top cover 2. The bottom of the bolts 22 passes through the top of the top cover 2 and is threaded into the inside of the positioning pins 13. A sealing gasket 23 is fixedly connected to the bottom of the top cover 2. The bottom of the sealing gasket 23 is in contact with the top of the mixing tank 1.
[0024] The top cover 2 includes a power mechanism 3. A motor 31 is fixedly mounted on the top of the top cover 2 via a mounting bracket. A transmission rod 32 is fixedly sleeved on the output shaft of the motor 31. The transmission rod 32 is rotatably connected to the inside of the top cover 2. An installation plate 41 is fitted into the inner wall of the installation groove 12. A handle 42 is symmetrically provided on the top of the installation plate 41. A first stirring shaft 43 is rotatably connected to the center of the installation plate 41. A connecting seat 44 is fixedly connected to the top of the first stirring shaft 43. The bottom end of the transmission rod 32 is fitted into the slot at the top of the connecting seat 44.
[0025] During use, the positioning groove 21 and the positioning pin 13 are engaged to achieve precise positioning of the top cover 2 on the mixing tank 1, avoiding installation misalignment; at this time, the sealing gasket 23 at the bottom of the top cover 2 contacts the top of the mixing tank 1, initially forming a seal, and the top cover 2 is firmly fixed on the mixing tank 1 by the tightening force of the bolt 22. At the same time, the sealing gasket 23 is compressed, enhancing the sealing between the mixing tank 1 and the top cover 2, and preventing material leakage.
[0026] When inspecting or replacing components, first loosen bolt 22 so that the bottom end of bolt 22 is disengaged from the locating pin 13, thus releasing the fixation between the top cover 2 and the mixing tank 1. Then lift the top cover 2 upwards so that the locating groove 21 at the bottom of the top cover 2 is separated from the locating pin 13 at the top of the mixing tank 1. At the same time, the bottom end of the transmission rod 32 is disengaged from the slot at the top of the connecting seat 44. Remove the top cover 2 and the power mechanism 3 at the top as a whole, exposing the mounting groove 12 at the top of the mixing tank 1 and the internal mixing mechanism 4 and other components.
[0027] Finally, grasp the handle 42 at the top of the mounting plate 41 and lift the mounting plate 41 upwards to remove it from the mounting slot 12 of the mixing tank 1. At this time, the mixing mechanism 4 and other components can be inspected. If there is any damage, replace them directly.
[0028] This design allows the top cover 2 to be removed simply by loosening the bolts 22 during equipment maintenance. The separation design of the positioning groove 21 and the positioning pin 13 enables the top cover 2 and the power mechanism 3 to be quickly removed without complicated disassembly steps. The mounting plate 41 can be directly removed from the mounting groove 12 via the handle 42, facilitating the quick disassembly of the stirring mechanism 4. This significantly shortens the time for maintenance or replacement of parts, reducing equipment downtime losses. The initial contact of the sealing gasket 23 forms the first seal, and the tightening of the bolts 22 generates a compressive force on the sealing gasket 23, forming a second reinforced seal, which significantly improves the sealing performance of the mixing tank 1.
[0029] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the mixing tank 1 includes a mixing mechanism 4, and a toothed ring 48 is fixedly connected to the upper part of the inner wall of the mixing tank 1.
[0030] A connecting plate 45 is fixedly sleeved on the upper surface of the first stirring shaft 43, and a second stirring shaft 46 is rotatably connected to both ends of the connecting plate 45.
[0031] A gear 47 is fixedly sleeved on the upper surface of the second stirring shaft 46, and the surface of the gear 47 meshes with the inner side of the gear ring 48.
[0032] During use, the motor 31 is started, and its output shaft drives the transmission rod 32 to rotate. The transmission rod 32 drives the first stirring shaft 43 to rotate at the center of the mounting plate 41 through the connecting seat 44, which can stir the material in the central area of the mixing tank 1.
[0033] When the first stirring shaft 43 rotates, the connecting plate 45 will rotate synchronously with it, thereby driving the two second stirring shafts 46 to revolve around the first stirring shaft 43. When the second stirring shafts 46 revolve with the connecting plate 45, the gear 47 will roll on the tooth surface of the gear ring 48, thereby generating a rotational motion. This allows the area near the inner wall of the mixing tank 1 to be covered during the revolution, while the rotation itself further shears and mixes the surrounding materials, effectively avoiding the insufficient mixing of materials near the inner wall of the mixing tank 1 by traditional single stirring.
[0034] This design achieves all-round mixing of materials in the mixing tank 1 by combining the central stirring of the first stirring shaft 43 with the revolution and rotation of the second stirring shaft 46. This improves the uniformity of material mixing, eliminates the need to drive the second stirring shaft 46 separately, simplifies the structure, reduces energy consumption, and further adapts to the requirements of raw material mixing accuracy and efficiency in the production of high-strength environmentally friendly packaging bags.
[0035] Reference Figures 1-4 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that a heating plate 5 is fixedly installed on the inner wall of the mixing tank 1, and a heater 51 is provided on one side of the mixing tank 1. After the heater 51 is started, the heat generated by it is transferred to the heating plate 5. The heating plate 5 is in direct contact with the material in the mixing tank 1 to achieve heating or heat preservation of the material. This can prevent the material from cooling and clumping during the mixing process, and ensure uniform mixing and smooth subsequent discharge.
[0036] Several support legs 11 are fixedly connected to the bottom of the mixing tank 1, and a discharge valve 14 is provided at the center of the bottom of the mixing tank 1. The support legs 11 provide stable support for the device. When the material is fully mixed by the mixing mechanism 4 and reaches the required temperature, the discharge valve 14 is opened, and the mixed material flows out from the bottom of the tank under the action of gravity. The flow rate and discharge speed are controlled by the discharge valve 14.
[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. 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.
