Description

Technical Field

[0001] This utility model relates to the field of polyurethane adhesive technology, and in particular to an automated packaging equipment for polyurethane adhesive products. Background Technology

[0002] In the packaging process of polyurethane adhesive products, the uniformity of mixing and the degree of automation in packaging have a significant impact on product quality and production efficiency.

[0003] However, in the existing technology, the existing mixing mechanism is simple in design and the movement of the mixing rod is simple, which makes it difficult to ensure that the rubber is fully mixed and easily leads to unstable product quality; the rubber discharge process lacks a precise detection mechanism, making it impossible to accurately determine whether the packaging barrel is in place, which can easily cause rubber waste or packaging deviation; manual operation of valves and the start and stop of mixing equipment have low time control precision, which not only results in low packaging efficiency, but also makes it difficult to ensure packaging consistency. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide an automated packaging equipment for polyurethane adhesive products, which solves the problems of the simple design of the stirring mechanism and the simple movement of the stirring rod in the prior art, which makes it difficult to ensure that the adhesive is fully mixed and easily leads to unstable product quality; the lack of a precise detection mechanism in the adhesive discharge process makes it impossible to accurately determine whether the packaging barrel is in place, which easily leads to adhesive waste or packaging deviation; and the low precision of time control in manually operating valves and starting and stopping the stirring equipment, which not only results in low packaging efficiency but also makes it difficult to ensure packaging consistency.

[0005] The technical solution of this utility model is as follows: an automated packaging equipment for polyurethane adhesive products includes a mixing tank, a turntable rotatably connected inside the mixing tank, gears rotatably connected at equal intervals to the top of the turntable, toothed grooves equally spaced on the inner wall of the mixing tank, and the gears meshing with the corresponding toothed grooves. A stirring rod is rotatably connected at equal intervals to the bottom of the turntable, and stirring bars are fixedly connected at equal intervals to the outer sides of the stirring rods. The tops of the stirring rods penetrate the turntable and are fixedly connected to the corresponding gears. A fixed shaft is fixedly connected inside the mixing tank, and an auger is rotatably connected to the bottom of the fixed shaft. A connecting shaft is fixedly connected to the bottom of the turntable, with the bottom of the connecting shaft rotatably connected to the fixed shaft, and the top of the auger fixedly connected to the connecting shaft.

[0006] Through the aforementioned technical solution, the unique combined revolution and rotation of the gears enables the stirring rod and stirring bar to stir the polyurethane adhesive in the mixing tank from multiple angles, ensuring thorough mixing and avoiding dead zones or uneven mixing. Meanwhile, the rotation of the auger assists in conveying the adhesive at the bottom of the mixing tank, preparing it for smooth discharge into the packaging tank and improving the continuity of the overall packaging process.

[0007] In a preferred embodiment, a conical tube is fixedly connected to the bottom of the mixing tank, a discharge pipe is fixedly connected to the bottom of the conical tube, a valve is installed and connected to the outside of the discharge pipe, and the bottom of the auger extends through the conical tube into the interior of the discharge pipe.

[0008] The above technical solution, combining the conical tube and the discharge pipe, effectively guides the concentrated discharge of the adhesive material, reducing residue and stagnation at the bottom of the mixing tank. The auger's pushing action further ensures smooth discharge of the adhesive material, preventing problems such as adhesive stickiness that could hinder discharge, thereby improving packaging efficiency and ensuring a stable and efficient packaging process.

[0009] In a preferred embodiment, support columns are fixedly connected to both sides of the mixing tank, and a support plate is fixedly connected between the two support columns and below the mixing tank. The support plate is fixedly connected to the outer side of the conical tube.

[0010] The aforementioned technical solution, through the support structure formed by the support columns and support plates, greatly enhances the stability of the mixing tank and conical tube, effectively preventing shaking or displacement of the equipment during operation. This stable structural design not only helps ensure the precise execution of processes such as mixing, conveying, and discharging, but also reduces component wear caused by shaking, extends the service life of the equipment, and lowers maintenance costs.

[0011] In a preferred embodiment, a detection photoelectric sensor is fixedly connected to one side of one of the support columns, and a reflector is installed and connected to the other support column near the detection photoelectric sensor. The detection photoelectric sensor and the reflector are used in conjunction.

[0012] By employing the aforementioned technical solution, the combined use of photoelectric sensors and reflectors enables precise detection of the packaging drum's positioning, ensuring that the adhesive discharge action is triggered only when the drum is correctly positioned. This precise detection mechanism prevents aimless or erroneous adhesive discharge, reducing waste and simultaneously improving the automation and precision of the packaging process, making the entire process more intelligent and reliable.

[0013] In a preferred embodiment, fixed supports are fixedly connected to both sides of the support column, and fixed holes are opened at the bottom of each fixed support. A drive motor is fixedly connected to the top of the mixing tank, and the output shaft of the drive motor is fixedly connected to the turntable.

[0014] The above technical solutions, with their design of fixed supports and holes, make equipment installation simple and secure, adaptable to different work site requirements, and ensure stability during operation. The direct connection between the drive motor and the turntable reduces energy loss during power transmission, making power transmission more efficient. This ensures stable and reliable operation of mixing and conveying actions, providing a solid power foundation for the entire packaging process.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model provides a technical solution: including a mixing tank 1, a turntable 2 rotatably connected inside the mixing tank 1, gears 3 rotatably connected at equal intervals to the top of the turntable 2, toothed grooves 4 rotatably opened on the inner wall of the mixing tank 1, and gears 3 meshing with corresponding toothed grooves 4, stirring rods 5 rotatably connected at equal intervals to the bottom of the turntable 2, stirring rods 6 rotatably fixedly connected to the outer side of the stirring rods 5, the top of the stirring rods 5 penetrating the turntable 2 and fixedly connected to the corresponding gears 3, a fixed shaft 8 fixedly connected inside the mixing tank 1, an auger 9 rotatably connected to the bottom of the fixed shaft 8, a connecting shaft 7 fixedly connected to the bottom of the turntable 2, the bottom of the connecting shaft 7 rotatably connected to the fixed shaft 8, and the top of the auger 9 fixedly connected to the connecting shaft 7.

[0025] In this embodiment, when the packaging barrel reaches the sensing range of the detection photoelectric sensor 16 and the reflector 17, the detection photoelectric sensor 16 transmits a signal to trigger the drive motor 13 to start, and its output shaft drives the turntable 2 to rotate. At this time, the gears 3 evenly distributed on the top of the turntable 2 mesh with the tooth grooves 4 on the inner wall of the mixing barrel 1. This meshing relationship causes the gears 3 to not only revolve with the turntable 2, but also rotate on their own due to the interaction between the teeth, thereby driving the stirring rod 5 fixedly connected to the gears 3 and the stirring rod 6 on the outside of the stirring rod 5 to rotate synchronously. At the same time, the connecting shaft 7 at the bottom of the turntable 2 rotates with the turntable, driving the auger 9 fixedly connected to the connecting shaft 7 to rotate.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a conical tube 10 is fixedly connected to the bottom of the mixing tank 1, and a discharge pipe 11 is fixedly connected to the bottom of the conical tube 10. A valve 12 is installed and connected to the outside of the discharge pipe 11, and the bottom of the auger 9 extends through the conical tube 10 to the inside of the discharge pipe 11.

[0027] In this embodiment, during the rotation of the auger 9, its spiral blades push the well-stirred polyurethane adhesive in the mixing tank 1 downwards. The adhesive is then guided by the converging tube 10 and flows to the discharge pipe 11. When the detection photoelectric sensor 16 senses that the packaging tank is in place and triggers the valve 12 to open automatically, the adhesive flows out from the discharge pipe 11 and enters the packaging tank for packaging.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, support columns 14 are fixedly connected to both sides of the mixing tank 1, and a support plate 15 is fixedly connected between the two support columns 14 and below the mixing tank 1. The support plate 15 is fixedly connected to the outer side of the tapered tube 10.

[0029] In this embodiment, the support column 14 serves as the main support structure for the mixing tank 1, providing a solid support foundation for the mixing tank 1 and its internal components. The support plate 15 is fixedly connected between the two support columns 14 and tightly fixed to the outside of the tapered tube 10. During equipment operation, the support columns 14 and the support plate 15 jointly bear the weight of the mixing tank 1, the adhesive material, and the internal rotating parts, as well as the forces generated during operation.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a detection photoelectric sensor 16 is fixedly connected to one side of one of the support columns 14, and a reflector 17 is installed and connected to the other support column 14 near the detection photoelectric sensor 16. The detection photoelectric sensor 16 and the reflector 17 are used together.

[0031] In this embodiment, when the packaging barrel is conveyed between the detection photoelectric sensor 16 and the reflector 17, the light emitted by the detection photoelectric sensor 16 is reflected or blocked by the packaging barrel. The detection photoelectric sensor 16 senses the signal that the packaging barrel is in place and transmits the signal to the control system. After receiving the signal, the control system immediately triggers the drive motor 13 to start and simultaneously controls the valve 12 to open automatically, so that the adhesive in the mixing barrel 1 can accurately flow into the packaging barrel for packaging.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, fixed supports 18 are fixedly connected to both sides of the support column 14, and fixed holes 19 are opened at the bottom of the fixed supports 18. A drive motor 13 is fixedly connected to the top of the mixing tank 1, and the output shaft of the drive motor 13 is fixedly connected to the turntable 2.

[0033] In this embodiment, the fixed supports 18 on both sides of the support column 14 are used to securely install the equipment at the designated location in the work area through the fixing holes 19 at the bottom, using bolts or other connecting parts, ensuring that the equipment will not shift or shake during operation. The output shaft of the drive motor 13 is directly fixedly connected to the turntable 2. When the drive motor 13 is powered on, its output power is directly transmitted to the turntable 2 through the output shaft, causing the turntable 2 and its connected components to rotate.

[0034] Working principle:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, when the packaging barrel reaches the sensing range of the detection photoelectric sensor 16 and the reflector 17, the detection photoelectric sensor 16 transmits a signal to trigger the drive motor 13 to start, and its output shaft drives the turntable 2 to rotate. At this time, the gears 3 evenly distributed on the top of the turntable 2 mesh with the tooth grooves 4 on the inner wall of the mixing barrel 1. This meshing relationship causes the gears 3 to not only revolve with the turntable 2, but also rotate on their own due to the interaction between the teeth, thereby driving the stirring rod 5 fixedly connected to the gears 3 and the stirring rod 6 on the outside of the stirring rod 5 to rotate synchronously. At the same time, the connecting shaft 7 at the bottom of the turntable 2 rotates with the turntable, driving the auger 9 fixedly connected to the connecting shaft 7 to rotate. During the rotation of the auger 9, its spiral blades push the mixed polyurethane adhesive in the mixing barrel 1 downwards. The adhesive is guided by the converging tube 10 and flows to the discharge pipe 11. When the photoelectric sensor 16 detects the packaging drum's arrival and triggers the valve 12 to open automatically, the adhesive flows out from the discharge pipe 11 and enters the packaging drum for packaging. The support column 14, as the main support structure of the mixing drum 1, provides a solid support foundation for the mixing drum 1 and its internal components. The support plate 15 is fixedly connected between the two support columns 14 and tightly fixed to the outside of the tapered tube 10. During equipment operation, the support columns 14 and support plate 15 jointly bear the weight of the mixing drum 1, the adhesive, and the internal rotating parts, as well as the forces generated during operation. When the packaging drum is conveyed between the photoelectric sensor 16 and the reflector 17, the light emitted by the photoelectric sensor 16 is reflected or blocked by the packaging drum. The photoelectric sensor 16 senses the signal that the packaging drum is in place and transmits this signal to the control system. Upon receiving the signal, the control system immediately triggers the drive motor 13 to start, and simultaneously controls the valve 12 to open automatically, allowing the adhesive in the mixing tank 1 to accurately flow into the packaging tank for packaging. The fixed supports 18 on both sides of the support column 14, through the fixing holes 19 at the bottom, use bolts and other connecting parts to securely install the equipment in the designated location at the work site, ensuring that the equipment will not shift or shake during operation. The output shaft of the drive motor 13 is directly fixedly connected to the turntable 2. When the drive motor 13 is powered on, its output power is directly transmitted to the turntable 2 through the output shaft, driving the turntable 2 and its connected components to rotate.
