Description

Technical Field

[0001] This utility model relates to the field of plastic bottle production technology, and in particular to a mixing device for plastic bottle production. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials. After adding the corresponding organic solvents, they are heated at high temperatures and then molded into plastic containers through blow molding, extrusion blow molding, or injection molding. They are mainly used as disposable plastic packaging containers for liquids or solids such as beverages, food, pickles, honey, dried fruits, edible oils, and agricultural and veterinary drugs. Plastic bottles have the characteristics of being unbreakable, low cost, high transparency, and made from food-grade raw materials.

[0003] Chinese utility model patent with publication number CN219618227U discloses a plastic bottle raw material preparation device, belonging to the technical field of plastic bottle production equipment. It includes a processing tank with a processing chamber. The inner wall of the processing chamber is connected to a feeding sloping plate. The processing tank is equipped with an accelerating stirring component and a volume control mechanism. The upper end of the processing tank is connected to a feeding pipe, which is arranged corresponding to the volume control mechanism. A melting furnace is arranged at the inner end of the processing chamber. The melting furnace is located below the feeding sloping plate and is connected to the feeding sloping plate. The inner wall of the processing chamber is equipped with multiple evenly distributed heating plates. The accelerating stirring component and the volume control mechanism are both arranged above the melting furnace.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: during the mixing process, the ingredients tend to adhere to the inner wall of the processing tank. At this point, workers need to clean the ingredients adhering to the inner wall of the processing tank. However, the processing tank in the aforementioned device is completely sealed, which increases the difficulty of cleaning and thus raises the workload for the workers. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a mixing device for plastic bottle production.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mixing device for plastic bottle production, comprising a mixing tank with an open top, a plurality of support legs arranged in an array on the bottom surface of the mixing tank, a motor fixedly mounted on the bottom surface of the support legs, the output shaft of the motor passing through the mixing tank and extending into the mixing tank, a main stirring rod fixedly mounted at the end of the output shaft of the motor, a plurality of secondary stirring rods arranged in an array on the outer wall of the main stirring rod, a discharge pipe installed at the bottom of the mixing tank, and a cleaning component for cleaning the inner wall of the mixing tank mounted on the secondary stirring rods.

[0007] By adopting the above technical solution, when workers need to stir the plastic bottle raw materials, they need to put the plastic bottle raw materials into the stirring tank. Then, the workers need to start the motor, which causes the motor output shaft to rotate. This causes the main stirring rod to rotate under the action of the motor output shaft, and the auxiliary stirring rod to rotate following the main stirring rod, thus stirring the plastic bottle raw materials together. After stirring is complete, workers can clean the inner wall of the stirring tank using the cleaning component, thereby reducing the difficulty of cleaning the inner wall of the stirring tank.

[0008] Furthermore, a groove is provided on the side wall of the auxiliary stirring rod away from the main stirring rod. The cleaning assembly includes a sliding rod slidably disposed in the groove, a cleaning plate fixedly disposed on the side wall of the sliding rod away from the main stirring rod, and a threaded rod rotatably disposed in the groove. The threaded rod is threadedly connected to the sliding rod.

[0009] By adopting the above technical solution, when workers need to clean the inner wall of the mixing tank, they need to rotate the threaded rod, which causes the sliding rod to slide under the action of the threaded rod, thereby causing the cleaning plate to press against the inner wall of the mixing tank under the action of the sliding rod. At this time, workers need to start the motor, which causes the auxiliary stirring rod to rotate under the action of the motor, thereby causing the cleaning plate to scrape the inner wall of the mixing tank, thus reducing the difficulty of cleaning the inner wall of the mixing tank.

[0010] Furthermore, a rotating groove is formed on the upper surface of the main stirring rod, and a receiving groove is formed on the inner bottom wall of the rotating groove. A connecting groove is formed through the inner wall of the sliding groove, and the connecting groove passes through the main stirring rod and communicates with the receiving groove. A rotating rod is rotatably arranged in the rotating groove, and the lower end of the rotating rod extends into the receiving groove. A first bevel gear is sleeved on the outer wall of the rotating rod, and the first bevel gear is fixed to the rotating rod. The end of the threaded rod away from the cleaning plate extends into the receiving groove and is fixedly arranged with a second bevel gear. The first bevel gear and the second bevel gear mesh with each other.

[0011] By adopting the above technical solution, when the worker needs to rotate the threaded rod, the worker needs to rotate the rotating rod, which in turn causes the first bevel gear to rotate synchronously with the rotating rod under the action of the rotating rod. This causes the second bevel gear to rotate under the action of the first bevel gear, which in turn causes the threaded rod to rotate under the action of the second bevel gear. This causes the slide rod to slide under the action of the threaded rod. In this process, the difficulty for the worker to slide the slide rod is reduced, thereby reducing the difficulty of the worker's work.

[0012] Furthermore, an annular groove is formed on the inner wall of the rotating groove, and an annular block is rotatably arranged in the annular groove, the annular block being fixed to the rotating rod.

[0013] By adopting the above technical solution, when the operator rotates the rotating rod, the annular block rotates under the action of the rotating rod. During this process, the annular block limits the rotating rod, thereby reducing the probability of the rotating rod sliding, which in turn reduces the probability of the first bevel gear and the second bevel gear separating from each other, thus improving the stability of the device.

[0014] Furthermore, a limiting plate is fixedly installed on the inner wall of the slide groove, the threaded rod passes through the limiting plate and is rotatably connected to the limiting plate, and two limiting rings are sleeved on the outer wall of the threaded rod, with the side walls of the two limiting rings approaching each other abutting against the two opposite side walls of the limiting plate.

[0015] By adopting the above technical solution, the limiting ring and the limiting plate limit the threaded rod, thereby reducing the probability of the threaded rod slipping and improving the stability of the device.

[0016] Furthermore, a limiting groove is formed on the inner wall of the slide, and a limiting block is slidably arranged in the limiting groove, with the limiting block and the slide rod being fixed to each other.

[0017] By adopting the above technical solution, when the slide bar slides, the limiting block slides synchronously with the slide bar. During this process, the limiting block limits the slide bar, thereby reducing the probability that the slide bar will rotate synchronously with the threaded rod, thus improving the stability of the device.

[0018] Furthermore, a valve is installed on the discharge pipe.

[0019] By adopting the above technical solution, the valve reduces the difficulty for workers to open and close the discharge pipe, thereby reducing the difficulty of their work.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, when workers need to stir the plastic bottle raw materials, they must place the raw materials into the stirring tank. Then, the workers must start the motor, causing the motor output shaft to rotate. This causes the main stirring rod to rotate under the action of the motor output shaft, and the auxiliary stirring rod to rotate following the main stirring rod, thus stirring the plastic bottle raw materials together. After stirring is complete, workers can clean the inner wall of the stirring tank using the cleaning component, thereby reducing the difficulty of cleaning the inner wall of the stirring tank.

[0022] 2. In this application, when the worker needs to clean the inner wall of the mixing tank, the worker needs to rotate the threaded rod, which causes the sliding rod to slide under the action of the threaded rod, thereby causing the cleaning plate to press against the inner wall of the mixing tank under the action of the sliding rod. At this time, the worker needs to start the motor, which causes the auxiliary stirring rod to rotate under the action of the motor, thereby causing the cleaning plate to scrape the inner wall of the mixing tank, thus reducing the difficulty for the worker to clean the inner wall of the mixing tank;

[0023] 3. In this application, when the worker needs to rotate the threaded rod, the worker needs to rotate the rotating rod, which causes the first bevel gear to rotate synchronously with the rotating rod under the action of the rotating rod, thereby causing the second bevel gear to rotate under the action of the first bevel gear, which in turn causes the threaded rod to rotate under the action of the second bevel gear, thereby causing the slide rod to slide under the action of the threaded rod. In this process, the difficulty for the worker to slide the slide rod is reduced, thereby reducing the difficulty of the worker's work. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-4As shown in the illustration, this application discloses a mixing device for plastic bottle production, including a mixing tank 1, support legs 11, a motor 12, a main stirring rod 13, a secondary stirring rod 14, a discharge pipe 15, a cleaning assembly 3, a rotating rod 4, a first bevel gear 41, a second bevel gear 42, and an annular block 5. The mixing tank 1 is a cylindrical structure with an open top and a vertical axis. The support legs 11 are cylindrical rod-shaped structures with a vertical axis, and multiple support legs 11 are arranged in a parallel array on the bottom surface of the mixing tank 1. The motor 12 is fixedly mounted on the bottom surface of the support legs 11, and the axis of its output shaft coincides with the axis of the mixing tank 1. The output shaft of the motor 12 passes through the mixing tank 1 and extends into the mixing tank 1. The main stirring rod 13 is a cylindrical rod-shaped structure with its axis coincident with the axis of the output shaft of the motor 12, and the main stirring rod 13 is fixedly mounted at the end of the output shaft of the motor 12. The secondary stirring rod 14 is a cylindrical rod-shaped structure with a horizontal axis, and multiple secondary stirring rods 14 are arranged in a parallel array on the outer wall of the main stirring rod 13. The discharge pipe 15 is a rectangular tubular structure and is installed at the bottom of the mixing tank 1.

[0031] When workers need to stir the plastic bottle raw materials, they must place the raw materials into the stirring tank 1. Then, the workers must start the motor 12, causing its output shaft to rotate. This, in turn, causes the main stirring rod 13 to rotate, which in turn causes the auxiliary stirring rod 14 to rotate under the influence of the main stirring rod 13. Thus, the main stirring rod 13 and the auxiliary stirring rod 14 stir the plastic bottle raw materials. After stirring is complete, workers can clean the inner wall of the stirring tank 1 using the cleaning component 3, reducing the difficulty of cleaning the inner wall of the stirring tank 1.

[0032] A groove 2 is formed on the side wall of the auxiliary stirring rod 14 away from the main stirring rod 13. A cleaning component 3 is installed on the auxiliary stirring rod 14 for cleaning the inner wall of the mixing tank 1. The cleaning component 3 includes a slide rod 31, a cleaning plate 32, and a threaded rod 33. The slide rod 31 is a round rod structure, and its axis coincides with the axis of the auxiliary stirring rod 14. The slide rod 31 is slidably disposed in the groove 2. The cleaning plate 32 is fixedly disposed on the side wall of the slide rod 31 away from the main stirring rod 13 for cleaning the inner wall of the mixing tank 1. The threaded rod 33 is rotatably disposed in the groove 2, and its axis coincides with the axis of the slide rod 31. The threaded rod 33 is threadedly connected to the slide rod 31.

[0033] When the worker needs to clean the inner wall of the mixing tank 1, the worker needs to rotate the threaded rod 33, which causes the sliding rod 31 to slide under the action of the threaded rod 33, thereby causing the cleaning plate 32 to press against the inner wall of the mixing tank 1 under the action of the sliding rod 31. At this time, the worker needs to start the motor 12, which causes the auxiliary stirring rod 14 to rotate under the action of the motor 12, thereby causing the cleaning plate 32 to scrape the inner wall of the mixing tank 1, thus reducing the difficulty of cleaning the inner wall of the mixing tank 1.

[0034] A rotating groove 21 is formed on the upper surface of the main stirring rod 13. A receiving groove 22 is formed on the inner bottom wall of the rotating groove 21. A connecting groove 23 is formed through the inner wall of the sliding groove 2, and the connecting groove 23 passes through the main stirring rod 13 and communicates with the receiving groove 22. The rotating rod 4 is a round rod structure, and its axis coincides with the axis of the main stirring rod 13. The rotating rod 4 is rotatably set in the rotating groove 21, and its lower end extends into the receiving groove 22. The first bevel gear 41 is sleeved on the outer wall of the rotating rod 4, and its axis coincides with the axis of the rotating rod 4. The first bevel gear 41 and the rotating rod 4 are fixed to each other. The end of the threaded rod 33 away from the cleaning plate 32 extends into the receiving groove 22. The second bevel gear 42 is fixedly set on the side wall of the threaded rod 33 away from the cleaning plate 32, and its axis coincides with the axis of the threaded rod 33. The first bevel gear 41 and the second bevel gear 42 mesh with each other.

[0035] When the worker needs to rotate the threaded rod 33, the worker needs to rotate the rotating rod 4, which causes the first bevel gear 41 to rotate synchronously with the rotating rod 4 under the action of the rotating rod 4. This causes the second bevel gear 42 to rotate under the action of the first bevel gear 41, which in turn causes the threaded rod 33 to rotate under the action of the second bevel gear 42. This causes the slide rod 31 to slide under the action of the threaded rod 33. In this process, the difficulty for the worker to slide the slide rod 31 is reduced, thereby reducing the difficulty of the worker's work.

[0036] An annular groove 24 is provided on the inner wall of the rotating groove 21. The annular block 5 is rotatably disposed in the annular groove 24, and its axis coincides with the axis of the rotating rod 4. The annular block 5 and the rotating rod 4 are fixed to each other.

[0037] When the operator rotates the rotating rod 4, the annular block 5 rotates under the action of the rotating rod 4. During this process, the annular block 5 limits the rotating rod 4, thereby reducing the probability of the rotating rod 4 sliding, which in turn reduces the probability of the first bevel gear 41 and the second bevel gear 42 separating from each other, thus improving the stability of the device.

[0038] To improve the stability of the device, a limiting plate 6 is fixedly installed on the inner wall of the slide 2. The threaded rod 33 passes through the limiting plate 6 and is rotatably connected to it. Two limiting rings 61 are sleeved on the outer wall of the threaded rod 33, and the sidewalls of the two limiting rings 61 that are close to each other abut against the two opposite sidewalls of the limiting plate 6. The limiting rings 61 and the limiting plate 6 limit the threaded rod 33, thereby reducing the probability of the threaded rod 33 slipping and improving the stability of the device.

[0039] To improve the stability of the device, a limiting groove 25 is formed on the inner wall of the slide 2, and a limiting block 7 is slidably disposed in the limiting groove 25. The limiting block 7 is fixed to the slide rod 31. When the slide rod 31 slides, the limiting block 7 slides synchronously with the slide rod 31. During this process, the limiting block 7 limits the slide rod 31, thereby reducing the probability that the slide rod 31 will rotate synchronously with the threaded rod 33, thus improving the stability of the device.

[0040] To reduce the difficulty of the workers' work, a valve 8 is installed on the discharge pipe 15. Valve 8 reduces the difficulty for workers to open and close the discharge pipe 15, thereby reducing the difficulty of the workers' work.

[0041] The operating principle of the mixing device for plastic bottle production in this embodiment is as follows: When the operator needs to stir the plastic bottle raw materials, the operator needs to put the raw materials into the mixing tank 1. Then, the operator needs to start the motor 12, which causes the output shaft of the motor 12 to rotate. This causes the main stirring rod 13 to rotate under the action of the motor 12 output shaft, and the auxiliary stirring rod 14 to rotate following the main stirring rod 13. Thus, the main stirring rod 13 and the auxiliary stirring rod 14 stir the plastic bottle raw materials. After stirring is complete, the operator can clean the inner wall of the mixing tank 1 using the cleaning component 3, thereby reducing the difficulty of cleaning the inner wall of the mixing tank 1.

[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
