DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 and Figure 2As shown, a mixing device for producing air column packaging bags includes a mixing tank 1, a feeding port 4 connected to the inner cavity of the mixing tank 1 is fixedly connected to the upper end of the mixing tank 1, a heating structure 3 fixedly connected to the front of the outer surface of the mixing tank 1 is arranged at the lower part of the inner cavity, a discharge pipe 2 connected to the inner cavity of the mixing tank 1 is fixedly connected to the rear part of the outer surface of the mixing tank 1, a conversion structure 5 is arranged at the upper part of the inner cavity of the mixing tank 1, a hedging structure 6 is arranged at the lower end of the conversion structure 5, and a stirring structure 7 is arranged on the inner surface of the conversion structure 5.

[0035] The air column packaging bag is made of nylon film. During the manufacturing process, nylon particles need to be dissolved in a solvent to form a nylon film solvent, and then heated to form a viscous colloid and extruded through an extruder to form the nylon film raw material of the air column packaging bag.

[0036] Specifically, to achieve heating of the air column packaging bag raw materials, refer to Figure 3 The heating structure 3 includes an isolation plate 33 fixedly connected to the lower part of the inner cavity of the mixing tank 1, a plurality of heating rods 34 are fixedly connected to the upper end of the isolation plate 33 in a circular distribution, a distribution pipe 32 is fixedly connected to the lower ends of the plurality of heating rods 34, the front surface of the outer surface of the distribution pipe 32 passes through the front part of the inner cavity of the mixing tank 1, extends to the front end of the mixing tank 1 and is fixedly connected to a heating controller 31 fixedly connected to the front surface of the outer surface of the mixing tank 1.

[0037] The above-mentioned heating controller 31 is a conventional electric heating control device, which has been widely used in the prior art. In the present invention, it is only used to control the temperature change of the heating rod 34 to heat the nylon membrane solution to promote its reaction. The heating controller 31 is connected to the distribution pipe 32 through a wire tube, and enters each heating rod 34 through the distribution pipe 32. The heat exchange effect of the heating rod 34 is used to heat the solution in the inner cavity of the mixing tank 1, and during the heating process, the uniformity of the heating of the nylon membrane solvent is further ensured by cooperating with the hedge structure 6 and the stirring structure 7.

[0038] Simultaneously, the heating controller 31 can control the heating temperature range of the heating rod 34 to avoid a large difference between the temperature and the reaction temperature of the nylon membrane solution.

[0039] During the operation of this embodiment, nylon particles and solvent are first fed into the inner cavity of the mixing tank 1 through the feed port 4, and the stirring structure 7 is driven by a driving motor to stir the solvent and nylon particles. The stirring structure 7 is simultaneously driven to operate with the cooperation of the conversion structure 5 and the hedging structure 6 to mix the nylon particles with the solvent, and the mixed solvent is heated under the action of the heating controller 31 and the heating rod 34. During the heating process, the counter-stirring of the hedging structure 6 and the stirring structure 7 promotes the hedging of the nylon particles and the solvent, thereby accelerating the mixing efficiency and improving the uniformity of the mixture.

[0040] Embodiment 2: Based on Embodiment 1, this embodiment drives the transmission shaft 71 to rotate through a driving motor, and during the rotation of the transmission shaft 71, the connecting plate 72 and the connecting rod 73 are used to drive the stirring component 74 to rotate rapidly in the solvent, thereby stirring the solvent, and during the stirring process, the nylon membrane mixed solution at the bottom is transported upward through the action of the stirring component 74, so that it is fully mixed and dissolved with the upper solvent and nylon particles, thereby improving the mixing efficiency and uniformity, shortening the processing time, and improving the continuous production efficiency.

[0041] Specifically, in order to achieve the stirring of the air column packaging nylon film raw material, refer to Figure 4 and Figure 5 The stirring structure 7 includes a transmission shaft 71 fixedly connected to the inner surface of the bevel gear 52 located at the upper part, a connecting plate 72 is fixedly connected to the lower part of the outer surface of the transmission shaft 71, and a plurality of connecting rods 73 are fixedly connected to the outer surface of the connecting plate 72 in an annular distribution. The ends of the plurality of connecting rods 73 away from the connecting plate 72 are fixedly connected to a stirring assembly 74. The lower end of the transmission shaft 71 passes through the upper end of the isolation plate 33 and extends to the lower end of the isolation plate 33 and is fixedly connected to a driving motor fixedly connected to the bottom wall of the inner cavity of the mixing tank 1.

[0042] The above-mentioned driving motor is a driving device commonly used in existing equipment. In the present invention, it is only used to drive the transmission shaft 71 to rotate, and its model, size, installation method, wiring method, etc. are not described in detail.

[0043] The motor drives the transmission shaft 71 to rotate, and the transmission shaft 71 drives the connecting plate 72 to rotate and thereby drives the connecting rod 73 to rotate around the central axis of the transmission shaft 71. At this time, the stirring assembly 74 is driven by the connecting rod 73 to stir the inner cavity of the mixing tank 1.

[0044] Further, to facilitate mixing of the solvent with the nylon particles, see Figure 5 , Figure 6 , Figure 7 and Figure 8 The stirring assembly 74 includes a Y-shaped spoiler 741, a liquid inlet 746 is provided in the middle of the lower end of the triangular part of the Y-shaped spoiler 741, a mounting groove 751 is provided at the tail end of the liquid inlet 746, a conical groove 749 is provided on the side of the mounting groove 751 away from the liquid inlet 746, a straight groove 750 is provided on the side of the conical groove 749 away from the mounting groove 751, and a guide groove 747 connected to the inclined surface of the triangular part is symmetrically provided along the liquid inlet 746 at the lower end of the triangular part of the Y-shaped spoiler 741; the Y-shaped spoilers 741 are all inclined, and they are inclined at an angle of 45 degrees to the bottom wall of the inner cavity of the mixing tank 1.

[0045] The Y-shaped spoiler 741 can be regarded as a Y-shaped structure with two closed branches, and the whole is in an inclined state. During the stirring process, its triangular part is located at the bottom, and the rotation direction is consistent with the direction of the triangular part. During the rotation process, the Y-shaped spoiler 741 will rotate around the transmission shaft 71 against the water flow, and guide the solvent to enter the Y-shaped spoiler 741 through the liquid inlet 746 and the guide groove 747. The remaining unperforated parts of the triangular part of the Y-shaped spoiler 741 will collide with the solvent. In the direction of rotation of the solvent, the rotation speed of the impacted part of the solvent will be accelerated and impact into other mixed liquids, thereby causing the nylon particles and the solvent in the mixed liquid to collide and dissolve with each other, thereby accelerating its mixing rate.

[0046] Further, to guide the flow direction of the fluid, see Figure 6 , Figure 7 and Figure 8 The stirring assembly 74 also includes a straight groove 750 whose inner surface is linearly distributed and staggered with injection ports 743 connected to the outer surface of the Y-shaped spoiler 741. A plurality of injection ports 743 are fixedly connected to a diverter plate 748 on one side away from the conical groove 749. The arc surfaces of a plurality of diverter plates 748 are all oriented in the direction of the conical groove 749. An overflow port 744 connected to the straight groove 750 is provided at the upper end of the vertical portion of the Y-shaped spoiler 741. The inclined surfaces on both sides of the triangular portion of the Y-shaped spoiler 741 are fixedly connected with drainage ports 742 opening upward and connected to the guide groove 747 on the same side.

[0047] Further, in order to achieve the purpose of slowing down the solvent and disturbing the liquid flow trajectory to make it fully mixed, refer to Figure 7 The inner surface of the mounting groove 751 is symmetrically rotated along the liquid inlet 746 and connected with a resistance brush 745 , and the inner arc surface of the blade on the outer surface of the resistance brush 745 faces the direction of the liquid inlet 746 .

[0048] During the impact process, part of the solvent will enter the installation groove 751 through the liquid inlet 746, and impact on the blades of the resistance brush 745 under the action of inertial speed, and drive the resistance brush 745 to rotate. The resistance brush 745 will rotate faster and faster under the accumulated speed, and continue to squeeze the solvent in the installation groove 751 to accelerate its mixing. At the same time, the solvent squeezed by the resistance brush 745 enters the straight groove 750 along the tapered groove 749;

[0049] The solvent in the straight groove 750 will gradually move upward under the centrifugal force generated by the rotation of the Y-shaped spoiler 741, and will gradually be ejected outward along the injection port 743 under the distribution action of the diverter plate 748 and the injection port 743, and the excess solvent will be ejected to the upper part from the overflow port 744, and the solvent will enter the external mixed liquid at a certain speed, thereby impacting the nylon particles in the external solvent and reacting with them, thereby accelerating the dissolution.

[0050] At the same time, the solvent entering the drainage port 742 through the diversion groove 747 will also collide with this part of the solvent, further accelerating its reaction rate.

[0051] Embodiment 3: Based on embodiment 2, this embodiment further drives the hedging structure 6 through the cooperation of the conversion structure 5 and the stirring structure 7 to synchronously drive the fan plate 61 to rotate during the rotation of the transmission shaft 71, and drives the hedging stirring component 64 to operate through the interaction between the spur gear 62 and the gear ring 63. During the rotation of the fan plate 61, the hedging stirring component 64 is synchronously used to stir the solvent in the opposite direction, thereby causing the mixed liquid of the inner ring and the outer ring to heave, and by promoting the collision between the solvent and nylon particles in the mixed liquid, the nylon particles are dissolved in the solvent, thereby accelerating its reaction rate and dissolution efficiency and shortening the reaction time.

[0052] Specifically, in order to utilize the conversion structure 5 to drive the hedging structure 6 to operate synchronously with the power of the stirring structure 7, refer to Fig. 9 The conversion structure 5 includes a rectangular shell 51 fixedly connected to the top wall of the inner cavity of the mixing tank 1, and bevel gears 52 are rotatably connected to the upper and lower sides and one side of the inner surface of the rectangular shell 51. The three bevel gears 52 are meshed in pairs. The inner surface of the upper bevel gear 52 is fixedly connected to the stirring structure 7, and the lower end of the lower bevel gear 52 is fixedly connected to a connecting pipe 53. The outer surface of the connecting pipe 53 is fixedly connected to the hedging structure 6, and the inner surface of the connecting pipe 53 is rotatably connected to the stirring structure 7.

[0053] During the rotation of the transmission shaft 71, the upper bevel gear 52 will be driven to rotate, and the lower bevel gear 52 will be driven to rotate through the meshing of the three bevel gears 52. The transmission shaft 71 is directly connected to the bottom drive motor through the lower bevel gear 52, so the rotation of the lower bevel gear 52 and the transmission shaft 71 will not affect each other, thereby achieving the reverse rotation of the lower bevel gear 52 and the transmission shaft 71 through the meshing of the three bevel gears 52.

[0054] Further, in order to realize the operation of the follow-up stirring structure 7 and drive the counter-stirring component 64, refer to Fig. 9 and Fig.10 The hedging structure 6 includes a fan plate 61 fixedly connected to the outer surface of the connecting pipe 53 and a gear ring 63 fixedly connected to the upper inner surface of the mixing tank 1. The fan plate 61 is Y-shaped and a hedging stirring assembly 64 connected to the gear ring 63 is annularly arranged on its inner surface. Three spur gears 62 are rotatably connected to the upper end of the fan plate 61 in a ring-shaped manner, and the three spur gears 62 are all meshed with the gear ring 63.

[0055] When the fan plate 61 rotates following the lower bevel gear 52, the upper spur gear 62 meshes with the gear ring 63 and rotates following the rotation of the fan plate 61, thereby driving the counter-acting stirring assembly 64 to operate.

[0056] Further, in order to achieve sufficient mixing of the solvent material by stirring the nylon membrane solvent, refer to Fig.10 The counter-agitation assembly 64 includes a synchronous wheel 641 and a rotating shaft 643 fixedly connected to the lower end of the spur gear 62. The upper end of the rotating shaft 643 passes through the lower end of the fan plate 61 and extends to the inner cavity of the fan plate 61. The outer surface of the synchronous wheel 641 is wrapped with a belt 642 wrapped with the outer surface of the rotating shaft 643. The lower part of the outer surface of the rotating shaft 643 is fixedly connected to a mounting plate 644. The inner surface of the mounting plate 644 is annularly distributed and fixedly connected to a number of flow disturbance rods 645.

[0057] During the rotation of the spur gear 62, the synchronous wheel 641 will be synchronously driven to rotate. The synchronous wheel 641 is connected to the rotating shaft 643 by a belt 642. When the synchronous wheel 641 rotates, the rotating shaft 643 will be synchronously driven to rotate through the belt 642. The mounting plate 644 installed on the rotating shaft 643 will synchronously drive the spoiler rod 645 installed around it to rotate around the axis of the rotating shaft 643. During this process, the spoiler rod 645 will continue to stir the nylon particles and solvent in the inner cavity of the mixing tank 1, but under the action of the conversion structure 5, its rotation direction is opposite to that of the stirring component 74, and the solvent mixture is reversely stirred in the inner circle, so that the solvents in the inner and outer circles are impacted together due to the reverse stirring, thereby accelerating the reaction rate and shortening the reaction time.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
