Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, specifically to mixing equipment for the production of biodegradable plastics. Background Technology

[0002] Biodegradable plastics are a type of green and environmentally friendly plastic that can be completely degraded by microorganisms in nature into carbon dioxide, methane, water, mineralized inorganic salts of its constituent elements, and other harmless substances. With the continuous upgrading of plastic restriction orders, biodegradable plastics have come into the public eye. Biodegradable plastics are synthetic polymer chemical products made by mixing and stirring raw materials under certain temperature and pressure conditions, undergoing physical and chemical reactions. The mixing effect and control of reaction conditions have a significant impact on production quality.

[0003] First, various raw materials are added to a high-speed mixer according to a specific ratio. The mixing blades in the mixer stir and mix the raw materials. However, when the sealing cover is opened after mixing, the raw materials adsorbed on the sealing cover's rubber gasket may roll down to the edge of the mixer. When the sealing cover is closed, the granular raw materials may damage the rubber gasket on the sealing cover. Before each sealing cover is closed, workers need to wipe the edge of the mixer with a towel to remove any residual raw materials. This process of wiping the edge of the mixer every time is inconvenient for workers to walk around the mixer. Therefore, we propose a mixing equipment for biodegradable plastic production. Summary of the Invention

[0004] The purpose of this invention is to provide a mixing device for the production of biodegradable plastics, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for the production of biodegradable plastics, comprising: a mixing machine body;

[0006] The closing assembly is fixedly installed on the main body of the mixer and is used to protect the sealing gasket.

[0007] The cleaning component is fixedly mounted on the closure component and is used to clean the sealing gasket of the closure component.

[0008] Preferably, the main body of the mixer includes a mounting side plate, on which a drive motor is fixedly mounted. A lifting column is provided at the output end of the drive motor, and an extension plate is fixedly provided at the other end of the lifting column. A sealing cover is fixedly provided on one side of the extension plate.

[0009] Preferably, the closing component includes a mixing drum ring fixedly connected to the main body of the mixer, a protective ring is provided on the mixing drum ring, and an inner retaining ring is provided on the inner side of the protective ring, which is integrally fixed with the mixing drum ring. The height dimension of the inner retaining ring is the same as the thickness dimension of the protective ring.

[0010] Preferably, a fan-shaped force-bearing plate is fixedly provided on one side of the protective ring, and a drive tooth plate is provided on the other side of the force-bearing plate, with the drive tooth plate meshing with the force-bearing plate.

[0011] Preferably, the cleaning component includes guide posts fixedly connected to the closing component. Several guide posts are provided, and the guide posts are evenly distributed and inclined in a counterclockwise direction.

[0012] Preferably, the guide column has an internal gas storage chamber, the top of the gas storage chamber is fixedly equipped with a sealing ring, and the gas storage chamber has a push column that is slidably connected to the guide column.

[0013] Preferably, the outer wall of the pusher column is provided with a number of equidistant air passages, and the pusher column is provided with jet holes that communicate with the number of air passages. The number of pusher columns and the guide column have the same inclination direction and angle.

[0014] Preferably, a push plug is fixedly installed at the other end of the push column, and a push spring is installed below the push plug. The two ends of the push spring are fixedly connected to the push plug and the guide column, respectively.

[0015] Preferably, auxiliary components are fixedly embedded in the upper wall of the mixing drum ring.

[0016] Preferably, the auxiliary component includes a gasket ring, the outer wall of which has a plurality of air jets, the interior of which a plurality of reset rings are fixedly disposed, and the gasket ring has a plurality of equidistant through-holes, the through-holes being not connected to the interior of the gasket ring.

[0017] The present invention has at least the following beneficial effects:

[0018] In this invention, when the sealing cover is opened after mixing, the raw materials adsorbed on the sealing cover gasket may roll to the edge of the mixer. When the sealing cover is closed, the particulate raw materials may damage the gasket on the sealing cover. Before each sealing cover is closed, the operator needs to wipe the edge of the mixer with a towel to remove the residual raw materials. This is inconvenient for the operator to wipe the edge of the mixer every time. Therefore, when the sealing cover is opened, the cleaning component drives the protective ring of the closing component to rise and rotate a certain distance. This causes the upper surface of the protective ring to rub slightly against the sealing gasket of the opening sealing cover, thereby rubbing away the raw material residue adsorbed on the edge of the sealing gasket. At the same time, the cleaning component can blow air onto the sealing gasket to clean it. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-7 The present invention provides a technical solution: Embodiment 1, a mixing equipment for the production of biodegradable plastics, comprising: a mixing machine body 1;

[0029] Closure component 2 is fixedly installed on the main body 1 of the mixer and is used to protect the sealing gasket.

[0030] The cleaning component 3 is fixedly installed on the closing component 2. The cleaning component 3 is used to clean the sealing gasket of the closing component 2. First, various raw materials are added to the high-speed mixer according to the proportion. The mixing blades in the mixer mix the various raw materials. However, when the sealing cover 16 is opened after mixing, the raw materials adsorbed on the sealing cover 16 gasket may roll to the edge of the mixer. When the sealing cover 16 is closed, the particulate raw materials may damage the gasket on the sealing cover 16. Before each closing of the sealing cover 16, the staff needs to wipe the edge of the mixer with a towel to clean off the residual raw materials. The staff needs to wipe the edge of the mixer every time, which is inconvenient for the staff to wipe around the mixer. Therefore, when the sealing cover 16 is opened, the cleaning component 3 drives the protective ring 22 of the closing component 2 to rise and rotate a certain distance. This causes the upper surface of the protective ring 22 to rub slightly against the sealing gasket of the opening sealing cover 16, which can rub off the raw material residue adsorbed on the edge of the sealing gasket. At the same time, the cleaning component 3 can blow air onto the sealing gasket to clean it.

[0031] The main body 1 of the mixer includes a mounting side plate 13, on which a drive motor 19 is fixedly mounted. A lifting column 14 is provided at the output end of the drive motor 19, and an extension plate 15 is fixedly provided at the other end of the lifting column 14. A sealing cover 16 is fixedly provided on one side of the extension plate 15. When it is necessary to open the sealing cover 16, the drive motor 19 drives the lifting column 14 to rise a short distance, and then rotates the sealing cover 16 ninety degrees to disengage it from the main body 1 of the mixer. The outer wall of the sealing cover 16 is provided with several locking plates 17 for locking. The main body 1 of the mixer also includes a fixed barrel base 11 located below the main body 1 of the mixer. A machine base 12 is fixedly mounted below the fixed barrel base 11. A stirring motor 18 is provided on one side of the fixed barrel base 11. The stirring motor 18 drives the belt inside the machine base 12 to rotate, thereby driving the rotation of the stirring blade inside the main body 1 of the mixer to stir various plastic raw materials.

[0032] The closing component 2 includes a mixing drum ring 21 fixedly connected to the main body 1 of the mixer. A protective ring 22 is provided on the mixing drum ring 21. An inner retaining ring 23 is provided on the inner side of the protective ring 22 and is integrally fixed to the mixing drum ring 21. The height dimension of the inner retaining ring 23 is the same as the thickness dimension of the protective ring 22.

[0033] The cleaning component 3 includes guide posts 31 that are fixedly connected to the closing component 2. Several guide posts 31 are provided, and the several guide posts 31 are evenly distributed and inclined in a counterclockwise direction.

[0034] The guide column 31 has an internal gas storage chamber 34, the top of the gas storage chamber 34 is fixedly provided with a sealing ring 35, and the gas storage chamber 34 has an internal push column 32 that is slidably connected to the guide column 31.

[0035] The outer wall of the pusher post 32 is provided with several equidistant air passage holes 36. The pusher post 32 is provided with jet holes 33 that communicate with the several air passage holes 36. The top of the pusher post 32 passes through the protective ring 22. The several pusher posts 32 and the guide post 31 have the same tilt direction and angle.

[0036] A push plug 37 is fixedly installed at the other end of the push column 32. A push spring 38 is installed below the push plug 37. The two ends of the push spring 38 are fixedly connected to the push plug 37 and the guide column 31, respectively. When the sealing cover 16 is opened and lifted by the driven motor 19, several push springs 38 push several push columns 32 simultaneously, causing the push plug 37 to slide upward inside the air storage chamber 34. The push plug 37 compresses the air in the air storage chamber 34 into the air passage 36 and sprays it out from the jet hole 33. This sprays the air onto the sealing gasket on the sealing cover 16, which automatically cleans the sealing gasket. At the same time, the push column 32 extends from the guide column 31 and lifts the sealing cover 16, causing the sealing cover 16 to rotate a short distance. As the sealing cover 16 rotates, the sealing gasket rubs against the protective ring 22, which cleans the residue.

[0037] According to the above embodiments, in Embodiment 2, a fan-shaped force-bearing plate 24 is fixedly provided on one side of the protective ring 22, and a drive tooth plate 25 is provided on the other side of the force-bearing plate 24. The drive tooth plate 25 and the force-bearing plate 24 mesh with each other, and the other side of the drive tooth plate 25 is fixedly connected to the lifting column 14. Based on Embodiment 1, when the sealing cover 16 is opened and lifted by the drive machine 19, the drive tooth plate 25 can be driven to mesh with the force-bearing plate 24 while the lifting column 14 is rising. Thus, when the drive machine 19 rotates the sealing cover 16 ninety degrees, it drives the drive tooth plate 25 to rotate, thereby driving the force-bearing plate 24 to rotate through the drive tooth plate 25. This can provide power to the protective ring 22, causing the protective ring 22 to rotate a short distance along the path of the push column 32 extending from the guide column 31.

[0038] According to the above embodiments, in Embodiment 3, an auxiliary component 4 is fixedly embedded in the upper wall of the mixing drum ring 21.

[0039] The auxiliary component 4 includes a gasket 41. The outer wall of the gasket 41 has several air jets 42. Several reset rings 44 are fixedly installed inside the gasket 41. Several column holes 43 are evenly distributed on the gasket 41. The column holes 43 are not connected to the interior of the gasket 41. Based on the first embodiment, when the sealing cover 16 closes and presses the protective ring 22 to descend and reset, the protective ring 22 squeezes the gasket 41, causing the air in the gasket 41 to be ejected from the air jets 42. This can blow away the residue between the protective ring 22 and the mixing drum ring 21. Several guide columns 31 pass through the column holes 43. The air jets 42 are distributed between two adjacent guide columns 31.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
