Description

Technical Field

[0001] This utility model relates to the field of mixing and stirring devices, and more specifically, to a bidirectional stirring mechanism for adhesive production. Background Technology

[0002] In the adhesive production process, multiple components need to be mixed and stirred to ensure that the components are fully and evenly mixed. Usually, a mixing tank is used for stirring. The mixed materials are placed into a mixing drum, and a drive motor drives the rotating shaft to stir the mixed components in the mixing drum.

[0003] In the existing mixing components, when the materials are placed into the mixing tank, they may fall rapidly downwards due to their own gravity. This may result in the materials accumulating at the bottom of the mixing tank or being discharged directly through the discharge port near the bottom of the mixing tank before they have been fully mixed, thus reducing the quality of the mixed product. This needs to be improved.

[0004] A search revealed a mixing mechanism for producing adhesives, disclosed in Chinese Patent Publication No. CN210278865U. This device features a baffle plate positioned above the mixing assembly along its height. Multiple slots are formed on the baffle plate. When materials are placed into the mixing tank, they first rest on the baffle plate and then flow through the slots to the mixing assembly, where they are agitated. The baffle plate effectively slows down the rate at which the materials fall downwards due to their own weight, and also allows for "multiple small-batch" mixing, effectively improving the quality of the mixed materials.

[0005] However, in actual use, when the above-mentioned mixing mechanism is used to mix the adhesive raw materials entering the bucket, the heavy and light raw materials are prone to stratification in the bucket. It requires repeated stirring for a long time to ensure that the raw materials are fully mixed, which will reduce the production efficiency and mixing uniformity of the adhesive. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bidirectional stirring mechanism for adhesive production to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A bidirectional stirring mechanism for adhesive production includes a tank and a base frame fixedly connected to the bottom of the tank. Two feed pipes are connected to the surface of the tank, and a discharge pipe is connected to the lower surface of the tank. A solenoid valve is installed inside the discharge pipe. Multiple toothed grooves are formed on the inner surface of the tank, arranged in a circular array. A bidirectional stirring mechanism is rotatably connected to the inner surface of the tank. The bidirectional stirring mechanism includes a turntable disposed inside the tank. A rotating shaft is vertically inserted through the turntable, and the turntable and the rotating shaft are fixedly connected. The top end of the rotating shaft penetrates the tank and extends above it. Gears are rotatably connected to both sides of the upper surface of the turntable. The surfaces of two gears mesh with multiple toothed grooves on the inner surface of the tank, and gears are meshed on one side of each of the two gears. The outer side of the second gear is rotatably connected to the upper surface of the turntable; both gears are fixedly connected to the bottom sides with a stirring frame, which includes a second rotating shaft, two supports, and multiple arc-shaped support plates; the bottom end of the second rotating shaft passes through the turntable and extends below it; the two supports are distributed from top to bottom on the outer side of the second rotating shaft, and multiple arc-shaped support plates are fixedly connected between the two supports, arranged in a ring array between the two supports; a spiral blade is fixedly connected to the outer side of the first rotating shaft; two load-bearing rods are fixedly connected to the bottom side of the first rotating shaft, and the upper surface of the load-bearing rods is rotatably connected to the bottom end of the second rotating shaft; a stirring frame is fixedly connected to the bottom end of the first rotating shaft, and the stirring frame is in contact with the bottom of the inner cavity of the tank; a servo motor for driving the first rotating shaft is fixedly connected to the top of the tank; an auxiliary fusion mechanism is provided inside the tank.

[0008] By adopting the above technical solution, two driven rotating agitators are used in combination with spiral blades to stir the adhesive raw materials upward, so that the adhesive raw materials form strong convection and exchange in the tank, thereby improving the mixing speed of the adhesive raw materials.

[0009] As a further description of the above technical solution: the auxiliary fusion mechanism includes a cavity opened inside the tank body, and a heater is provided inside the cavity. A liquid outlet pipe and a liquid inlet pipe are connected to one side of the tank body. The liquid outlet pipe and the liquid inlet pipe are distributed from top to bottom on one side of the tank body. One end of the liquid outlet pipe is connected to an external water outlet pipe, and one end of the liquid inlet pipe is connected to an external water supply pipe.

[0010] By adopting the above technical solution, using a heater, an outlet pipe, and an inlet pipe to heat the adhesive raw material inside the tank in a water bath, the temperature difference between different areas inside the tank is reduced.

[0011] The technical effects and advantages of this utility model are as follows: 1. By setting up a bidirectional stirring mechanism, compared with the existing technology, the two stirring frames will repeatedly perform radial mixing in a planetary motion with the main shaft, and then perform axial mixing in combination with the spiral blades. This continuously lifts the heavy raw materials deposited at the bottom to the upper part of the tank. By combining radial mixing and axial mixing, a three-dimensional and complex flow field is formed, which makes the adhesive raw materials generate strong convection and exchange in various parts of the tank, improving the mixing speed of the adhesive raw materials while maintaining a high degree of mixing uniformity. 2. By setting up an auxiliary fusion mechanism, compared with the existing technology, water bath heating is achieved through the heater and the water injected into the tank cavity, so that the entire inner wall of the tank is transferred with heat, so that the adhesive raw materials can be heated synchronously and stably from the outside to the inside, reducing the temperature difference between different areas in the tank and maintaining the mixing effect of the adhesive raw materials.

[0020] 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.

[0021] The embodiments disclosed in this application are as follows: Figures 1-7 The illustrated bidirectional stirring mechanism for adhesive production includes a tank 1 and a base frame 2 fixedly connected to the bottom side of the tank 1. Two feed pipes 3 are connected to the surface of the tank 1, and a discharge pipe 4 is connected to the lower surface of the tank 1. A solenoid valve is installed inside the discharge pipe 4. Multiple toothed grooves 14 are formed on the inner surface of the tank 1, arranged in a circular array. A bidirectional stirring mechanism is rotatably connected to the inner side of the tank 1. The bidirectional stirring mechanism includes a turntable 5 disposed inside the tank 1, with vertically penetrating the turntable 5. A rotating shaft 6 is installed, and a rotating disk 5 is fixedly connected to the rotating shaft 6. The top end of the rotating shaft 6 passes through the tank body 1 and extends to the top of the tank body 1. Gears 7 are rotatably connected to both sides of the upper surface of the rotating disk 5. The surfaces of the two gears 7 mesh with multiple tooth grooves 14 on the inner surface of the tank body 1. Gears 8 are meshed on one side of each of the two gears 7. The outer side of the gears 8 is rotatably connected to the upper surface of the rotating disk 5. A stirring frame is fixedly connected to the bottom side of each of the two gears 8. The stirring frame includes a rotating shaft 9, two supports 10, and multiple arcs. A shaped support plate 11 is provided; the bottom end of the second rotating shaft 9 passes through the turntable 5 and extends below the turntable 5; two supports 10 are distributed from top to bottom on the outside of the second rotating shaft 9, and multiple arc-shaped support plates 11 are fixedly connected between the two supports 10. Multiple arc-shaped support plates 11 are arranged in a ring array between the two supports 10; a spiral blade 12 is fixedly connected to the outside of the first rotating shaft 6; two load-bearing rods are fixedly connected to the bottom side of the first rotating shaft 6, and the upper surface of the load-bearing rods is rotatably connected to the bottom end of the second rotating shaft 9; an agitator 13 is fixedly connected to the bottom end of the first rotating shaft 6. The stirring frame 13 is fitted to the bottom of the inner cavity of the tank 1, and a servo motor 18 for driving the rotating shaft 6 is fixedly connected to the top of the tank 1. An auxiliary fusion mechanism is provided inside the tank 1. Two gears 7 and 8 rotate planetarily with the rotation of the turntable 5. Combined with the rotation of the spiral blade 12, the adhesive raw material can flow up and down inside, which improves the shear force on the adhesive raw material and reduces the mixing dead angle inside the tank 1, thereby improving the mixing efficiency and uniformity of the adhesive raw material.

[0022] Reference Figure 1 , Figure 3 and Figure 6As shown, the auxiliary fusion mechanism includes a cavity opened inside the tank body 1, and a heater 15 is provided inside the cavity. A liquid outlet pipe 16 and a liquid inlet pipe 17 are connected to one side of the tank body 1. The liquid outlet pipe 16 and the liquid inlet pipe 17 are distributed from top to bottom on one side of the tank body 1. One end of the liquid outlet pipe 16 is connected to an external water outlet pipe, and one end of the liquid inlet pipe 17 is connected to an external water supply pipe. By using the liquid outlet pipe 16, the liquid inlet pipe 17, and the heater 15 in the cavity of the tank body 1, stable water bath heating of the adhesive raw material inside the tank body 1 is achieved, so that the adhesive raw material maintains effective fluidity.

[0023] The working principle of this utility model is as follows: In the process of adhesive production, various adhesive raw materials are first put into the tank 1 through two feed pipes 3, and the external water supply pipe is opened to continuously input water into the inside of the liquid inlet pipe 17 so that the water completely fills the cavity inside the tank 1. Then the heater 15 is started to heat the water to a certain extent so that the adhesive raw materials inside the tank 1 maintain effective flow. Then, the servo motor 18 is started to drive the rotating shaft 6 to rotate the turntable 5 inside the tank 1. When the turntable 5 rotates, the two gears 7 on the upper surface of the turntable 5 will revolve with the turntable 5. Then, the two gears 7 will mesh with the multiple tooth grooves 14 on the inner surface of the tank 1 and be driven to rotate on their own axis. The two gears 7 will mesh with the gear 8 on one side to transmit power. Then, the two gears 8 will drive the two rotating shafts 9 to rotate inside the tank 1. The two rotating shafts 9 will drive the two supports 10 and multiple arc-shaped support plates 11 on their surfaces to repeatedly stir the adhesive material inside the tank 1. At the same time, the spiral blades 12 on the surface of the rotating shaft 6 will continuously stir the adhesive material on the bottom side of the tank 1 upwards in a spiral motion, so that the adhesive material is vertically stirred, and thus the adhesive material is fully stirred. It is worth noting that the adhesive raw material is fully agitated inside the tank 1, and the hot water in the cavity of the tank 1 keeps the adhesive raw material inside the tank 1 in an effective flow, thereby making the agitation of the adhesive raw material more thorough and accelerating the production efficiency of the adhesive. Meanwhile, when outputting the adhesive, the solenoid valve inside the discharge pipe 4 is opened first, so that the adhesive raw material flows out through the discharge pipe 4. The agitator 13 at the bottom of the rotating shaft 6 scrapes the adhesive raw material at the bottom of the tank 1 to assist in the feeding of the adhesive raw material, thus maintaining the continuous feeding of the adhesive raw material.
